UK society is undergoing a technological revolution, including meeting health needs through technology. Government policy is shifting towards a "digital by default" position. Studies have trialled health technology interventions for those experiencing psychosis and shown them to be useful. To gauge levels of engagement with mobile phones (Internet-enabled or cell phone), computers and the Internet in the specific population of community mental health rehabilitation. Two surveys were conducted: with service-users on use/non-use of technologies, and interest in technology interventions and support; and with placements on facilities and support available to service-users. Levels of engagement in this population were substantially less than those recorded in the general UK and other clinical populations: 40.2% regularly use mobiles, 17.5% computers, and 14.4% the Internet. Users of all three technologies were significantly younger than non-users. Users of mobiles and computers were significantly more likely to live in lower support/higher independence placements. Of surveyed placements, 35.5% provide a communal computer and 38.7% IT skills sessions. Community mental health rehabilitation service-users risk finding themselves excluded by a "digital divide". Action is needed to ensure equal access to online opportunities, including healthcare innovations. Clinical and policy implications are discussed.

Specialist supported accommodation services have become a key component of most community-based mental healthcare systems. While mental health policies highlight the importance of service user involvement in service development and care planning, there are no comprehensive literature reviews synthesising services users' perspectives on, or experiences of, supported accommodation services. This systematic review was undertaken to fill this gap. We searched electronic databases (January 2015, updated June 2017), conducted hand searches and used forward-backward snowballing to identify 13,678 papers. We inspected the full-text of 110 papers and included 50 of these in the final review. Data extraction and quality assessments were conducted. We used narrative synthesis to develop a conceptual model of service users' experiences that included structural, process, relational and contextual factors, such as the characteristics of the service, relationships with staff and other service users, the intensity and nature of support, the physical environment, and social and community integration. The review highlights the complex interplay of individual, service-level and community factors in shaping the lived experience of service users and their impact on personal identity and recovery. Our approach addressed some of the widely reported limitations of the quantitative research in this field, providing a conceptual model relevant to service user experiences across supported accommodation service types, population groups and countries. © 2018 John Wiley & Sons Ltd.

NASA continues to improve the Earth Science Directorate in the areas of thematic integration, stakeholder feedback and Project Applications Program tailoring for missions to transfer knowledge between scientists and projects. The integration of application themes and the implementation of application science activities in flight projects have evolved to formally include user feedback and stakeholder integration. NASA's new Flight Applied Science Program Guidelines are designed to bridge NASA Earth Science Directorates in Flight, Applied Sciences and Research and Development by agreeing to integrate the user community into mission life cycles. Thus science development and science applications will guide all new instruments launched by NASAs ESD. The continued integration with the user community has enabled socio-economic considerations into NASA Earth Science projects to advance significantly. Making users a natural part of mission science leverages future socio-economic impact research and provides a platform for innovative and more actionable product to be used in decision support systems by society. This presentation will give an overview of the new NASA Guidelines and provide samples that demonstrate how the user community can be a part of NASA mission designs.

It is now well established that pursuing generic solutions to what seem are common problems in Earth science data access and use can often lead to disappointing results for both system developers and the intended users. This presentation focuses on real-world experience of managing a large and complex data system, NASA's Earth Science Data and Information Science System (EOSDIS), whose mission is to serve both broad user communities and those in smaller niche applications of Earth science data and services. In the talk, we focus on our experiences with known data user obstacles characterizing EOSDIS approaches, including various technological techniques, for engaging and bolstering, where possible, user experiences with EOSDIS. For improving how existing and prospective users discover and access NASA data from EOSDIS we introduce our cross-archive tool: Earthdata Search. This new search and order tool further empowers users to quickly access data sets using clever and intuitive features. The Worldview data visualization tool is also discussed highlighting how many users are now performing extensive data exploration without necessarily downloading data. Also, we explore our EOSDIS data discovery and access webinars, data recipes and short tutorials, targeted technical and data publications, user profiles and and social media as additional tools and methods used for improving our outreach and communications to a diverse user community. These efforts have paid substantial dividends for our user communities by allowing us to target discipline specific community needs. The desired take-away from this presentation will be an improved understanding of how EOSDIS has approached, and in several instances achieved, removing or lowering the barriers to data access and use. As we look ahead to more complex Earth science missions, EOSDIS will continue to focus on our user communities, both broad and specialized, so that our overall data system can continue to serve the needs of science and applications users.

Joseph, Kenneth; Carley, Kathleen M.

2017-01-01

The Islamic State of Iraq and ash-Sham (ISIS) continues to use social media as an essential element of its campaign to motivate support. On Twitter, ISIS’ unique ability to leverage unaffiliated sympathizers that simply retweet propaganda has been identified as a primary mechanism in their success in motivating both recruitment and “lone wolf” attacks. The present work explores a large community of Twitter users whose activity supports ISIS propaganda diffusion in varying degrees. Within this ISIS supporting community, we observe a diverse range of actor types, including fighters, propagandists, recruiters, religious scholars, and unaffiliated sympathizers. The interaction between these users offers unique insight into the people and narratives critical to ISIS’ sustainment. In their entirety, we refer to this diverse set of users as an online extremist community or OEC. We present Iterative Vertex Clustering and Classification (IVCC), a scalable analytic approach for OEC detection in annotated heterogeneous networks, and provide an illustrative case study of an online community of over 22,000 Twitter users whose online behavior directly advocates support for ISIS or contibutes to the group’s propaganda dissemination through retweets.

The exponential growth of genomic data from next generation technologies renders traditional manual expert curation effort unsustainable. Many genomic systems have included community annotation tools to address the problem. Most of these systems adopted a "Wiki-based" approach to take advantage of existing wiki technologies, but encountered obstacles in issues such as usability, authorship recognition, information reliability and incentive for community participation. Here, we present a different approach, relying on tightly integrated method rather than "Wiki-based" method, to support community annotation and user collaboration in the Integrated Microbial Genomes (IMG) system. The IMG approach allows users to use existing IMG data warehouse and analysis tools to add gene, pathway and biosynthetic cluster annotations, to analyze/reorganize contigs, genes and functions using workspace datasets, and to share private user annotations and workspace datasets with collaborators. We show that the annotation effort using IMG can be part of the research process to overcome the user incentive and authorship recognition problems thus fostering collaboration among domain experts. The usability and reliability issues are addressed by the integration of curated information and analysis tools in IMG, together with DOE Joint Genome Institute (JGI) expert review. By incorporating annotation operations into IMG, we provide an integrated environment for users to perform deeper and extended data analysis and annotation in a single system that can lead to publications and community knowledge sharing as shown in the case studies.

Unidata's core mission is to serve academic research and education communities by facilitating access and use of real-time weather data. To this end, Unidata develops, distributes, and supports several Free and Open Source Software (FOSS) packages. These packages are largely focused on data management, access, analysis and visualization. This presentation will discuss the lessons Unidata has gathered over thirty years of FOSS development, support, and community building. These lessons include what it takes to be a successful FOSS organization, how to adapt to changing "best practices" and the emergence of new FOSS tools and services, and techniques for dealing with software end-of-life. We will also discuss our approach when supporting a varied user community spanning end users and software developers. Strong user support has been an important key to Unidata's successful community building.

Loyalty in Online Communities.

Loyalty is an essential component of multi-community engagement. When users have the choice to engage with a variety of different communities, they often become loyal to just one, focusing on that community at the expense of others. However, it is unclear how loyalty is manifested in user behavior, or whether certain community characteristics encourage loyalty. In this paper we operationalize loyalty as a user-community relation: users loyal to a community consistently prefer it over all others; loyal communities retain their loyal users over time. By exploring a large set of Reddit communities, we reveal that loyalty is manifested in remarkably consistent behaviors. Loyal users employ language that signals collective identity and engage with more esoteric, less popular content, indicating that they may play a curational role in surfacing new material. Loyal communities have denser user-user interaction networks and lower rates of triadic closure, suggesting that community-level loyalty is associated with more cohesive interactions and less fragmentation into subgroups. We exploit these general patterns to predict future rates of loyalty. Our results show that a user's propensity to become loyal is apparent from their initial interactions with a community, suggesting that some users are intrinsically loyal from the very beginning.

The National Snow and Ice Data Center (NSIDC) at the University of Colorado is known for its customer service. Through the User Services Office (USO) NSIDC provides end-to-end data support with timely, friendly, and professional assistance. This service includes expertise in selecting, obtaining, and handling of data, as well as the dissemination of information related to NSIDC’s cryospheric data and information. This dissemination happens across many mediums, such as email, newsletters, and Web-published data documentation. With surveys like the American Customer Service Index, we are learning more and more about what the user’s informational needs are, and beginning to anticipate what the user's needs might be in the future. In this presentation, we will examine the current USO processes for communicating with our user community, and explore how social networking tools, such as Twitter, Blogging, or Facebook may enhance the overall user experience. We will assess a communication approach that combines mainstream and emerging technologies in order to maintain a high standard of customer service with an expanding cryospheric user community.

Evolution of the EOSDIS Data User Communities

Since NASA's EOS Terra platform began operations in early FY2000, data centers affiliated with the EOS Data and Information System (EOSDIS) have distributed over 12.8 Petabytes (PB) and 1.2 billion files of data to over 2.3 million distinct users through the end of FY2010. Metrics on data ingest, archive, and distribution have been collected throughout the EOS era by different automated systems. The functionality of these systems has improved over the years, allowing more types of metrics analyses to be made with greater precision. The ESDIS Metrics System (EMS) replaced the earlier ESDIS Data Gathering and Reporting System (EDGRS) in FY2005. Since then it has collected increasingly more accurate information about data users obtaining products from the many EOSDIS data centers. The information allows characterization of the various EOSDIS user communities, and enables studies of how these communities have changed over time. User information obtained when an order is placed, or products are downloaded from a data center's FTP site, include the user's IP host (or IP address) and email address. The EMS system is able to resolve most IP addresses to specific domains. Combined with science discipline information associated with the data products themselves, users and data distributions to them can be characterized in a number of ways, including by countries, disciplines (e.g. Atmosphere, Ocean, Land), and [most readily for the United States] affiliations (Government, Education, Non-profit, or Commercial). The purpose of this investigation is to analyze patterns of data distributions within the different user groups mentioned above and to trace their evolution over time. Results show, for example, that the number of foreign users has increased greatly over the years, as has the number of countries receiving EOSDIS data products. These kinds of studies can be very useful to the various data centers. By gaining a better understanding of how their user communities are evolving, and how patterns of data product distributions are changing, data centers will be better able to serve the needs of the users.

Supporting Shared Resource Usage for a Diverse User Community: the OSG Experience and Lessons Learned

The Open Science Grid (OSG) supports a diverse community of new and existing users in adopting and making effective use of the Distributed High Throughput Computing (DHTC) model. The LHC user community has deep local support within the experiments. For other smaller communities and individual users the OSG provides consulting and technical services through the User Support area. We describe these sometimes successful and sometimes not so successful experiences and analyze lessons learned that are helping us improve our services. The services offered include forums to enable shared learning and mutual support, tutorials and documentation for new technology, and troubleshooting of problematic or systemic failure modes. For new communities and users, we bootstrap their use of the distributed high throughput computing technologies and resources available on the OSG by following a phased approach. We first adapt the application and run a small production campaign on a subset of “friendly” sites. Only then do we move the user to run full production campaigns across the many remote sites on the OSG, adding to the community resources up to hundreds of thousands of CPU hours per day. This scaling up generates new challenges - like no determinism in the time to job completion, and diverse errors due to the heterogeneity of the configurations and environments - so some attention is needed to get good results. We cover recent experiences with image simulation for the Large Synoptic Survey Telescope (LSST), small-file large volume data movement for the Dark Energy Survey (DES), civil engineering simulation with the Network for Earthquake Engineering Simulation (NEES), and accelerator modeling with the Electron Ion Collider group at BNL. We will categorize and analyze the use cases and describe how our processes are evolving based on lessons learned.

Patient and public involvement (PPI) in research has expanded nationally and internationally over the last decade, and recently there has been significant attention given to understanding its impact on research. Less attention has been given to the impact of PPI on the people involved, yet it has been shown that the success of PPI in research can be reliant on the processes of engagement between these individuals and communities. This paper therefore critically explores the impact of PPI on service users, researchers and communities involved in health and social care research. Searches were undertaken from 1995 to April 2012 in the electronic databases MEDLINE, EMBASE, PsycINFO, Cochrane library, CINAHL, HMIC and HELMIS. Searches were undertaken for grey literature using the databases InvoNet and NHS Evidence. Studies were included if they included the impact of PPI on individual service users, researchers or communities under research. Studies were excluded if they were in a foreign language (unless they were deemed critical to the systematic review) or were in children and adolescent services. Data were extracted using a narrative synthesis, and quality was assessed using the Critical Appraisal Skills Programme. Service users reported feeling empowered and valued, gaining confidence and life skills. Researchers developed a greater understanding and insight into their research area, gaining respect and a good rapport with the community. The community involved in research became more aware and knowledgeable about their condition. However, lack of preparation and training led some service users to feel unable to contribute to the research, while other service users and communities reported feeling overburdened with the work involved. Researchers reported difficulties in incorporating PPI in meaningful ways due to lack of money and time. This is the first international systematic review to focus on the impact of PPI on the people involved in the process. The beneficial and challenging impacts reported highlight the importance of optimising the context and processes of involvement, so creating the potential for PPI to impact positively on the research itself.

This annual update of the Information Gateway Plan incorporates changes recommended by the Socioeconomic Data and Applications Center (SEDAC) User Working Group (UWG) and reflects comments and suggestions from users, collaborators, and the Contracting Officer Technical Representative (COTR). The Information Gateway Plan is a concise and specific plan that outlines SEDAC activities and services in support of the earth and social sciences and other user communities. The SEDAC Information Gateway effort is a primary means by which the Earth Observing System Data and Information System (EOSDIS) can link meaningfully with a broad range of social science data sources and users in ways that lead to tangible benefits to the American people. The SEDAC Information Gateway provides interdisciplinary access to socioeconomic and physical science data and information resources held by SEDAC and numerous other institutions and networks around the world. The Plan describes the areas of research of earth scientists and socioeconomic scientists where interchange of data and information is most needed. It sets guidelines for the continued development of SEDAC's directory of social science datasets and establishes priorities for efforts to make data held by SEDAC or accessible through SEDAC available to the user community. The Plan also describes the means by which the SEDAC user community can access information products specified by the SEDAC Data and Applications Development Plan (DADP). Among other major activities, SEDAC will continue to enhance and operate a directory capability, interoperable with the Global Change Master Directory, that provides the socioeconomic community with information about earth science products and the earth science research community with information about socioeconomic data. The Information Gateway also serves as a unique and powerful access pathway for a wide range of users and potential users of socioeconomic and earth science data, including especially remote sensing data.

It is essential to involve service users in efforts to expand access to mental health care in integrated primary care settings in low- and middle-income countries (LMICs). However, there is little evidence from LMICs to guide this process. The aim of this study was to explore barriers to, and facilitators of, service user/caregiver involvement in rural Ethiopia to inform the development of a scalable approach. Thirty nine semi-structured interviews were carried out with purposively selected mental health service users (n = 13), caregivers (n = 10), heads of primary care facilities (n = 8) and policy makers/planners/service developers (n = 8). The interviews were audio-recorded and transcribed in Amharic, and translated into English. Thematic analysis was applied. All groups of participants supported service user and caregiver involvement in mental health system strengthening. Potential benefits were identified as (i) improved appropriateness and quality of services, and (ii) greater protection against mistreatment and promotion of respect for service users. However, hardly any respondents had prior experience of service user involvement. Stigma was considered to be a pervasive barrier, operating within the health system, the local community and individuals. Competing priorities of service users included the need to obtain adequate individual care and to work for survival. Low recognition of the potential contribution of service users seemed linked to limited empowerment and mobilization of service users. Potential health system facilitators included a culture of community oversight of primary care services. All groups of respondents identified a need for awareness-raising and training to equip service users, caregivers, service providers and local community for involvement. Empowerment at the level of individual service users (information about mental health conditions, care and rights) and the group level (for advocacy and representation) were considered essential, alongside improved, accessible mental health care and livelihood interventions. As Ethiopia increases access to mental health care, a fundamental barrier to service user involvement is beginning to be addressed. Our study identified further barriers that need to be tackled, including a supportive political climate, and receptiveness amongst stakeholders. The findings will inform the development of a model of service user involvement, which will be piloted and evaluated.

The Gemini Science User Support Department (SUSD) was formed a little more than a year ago to create a collaborative community of users and staff and to consolidate existing post-observing support throughout the observatory for more efficient use of resources as well as better visibility amongst our user community. This poster is an opportunity to exchange ideas about how Gemini can improve your experience while working with the Observatory and present details about new avenues of post-observing support coming soon. We encourage your feedback at any time.Shortly after its creation, the SUSD conducted a complete revision of the communication cycle between Gemini and its community of researchers. The cycle was then revisited from the perspective of an astronomer interested in using Gemini for their research. This exercise led to a series of proposed changes that are currently under development, and the implementation of a sub-selection is expected in 2016, including the following. (1) Email notifications: Gemini users will receive new forms of email communications that are more instructive and tailored to their program. The objective is to direct the users more efficiently toward the useful links and documentation all along the lifecycle of the program, from phaseII to after the data are completely reduced. (2) HelpDesk system: The HelpDesk will become more user-friendly and transparent. (3) Webpages: The organization of the Gemini webpages will be redesigned to optimize navigation; especially for anything regarding more critical periods likes phaseIs and phaseIIs. (4) Data Reduction User Forum: Following recommendations from Gemini users, new capabilities were added to the forum, like email notifications, and a voting system, in order to make it more practical. This forum's objective is to bring the Gemini community together to exchange their ideas, thoughts, questions and solutions about data reduction, a sort of Reddit, StackOverflow or Slashdot for Gemini data.

EPA Pesticide Factsheets

EPA’s Sustainable and Healthy Communities (SHC) Research Program is developing methodologies, resources, and tools to assist community members and local decision makers in implementing policy choices that facilitate sustainable approaches in managing their resources affecting the built environment, natural environment, and human health. In order to assist communities and decision makers in implementing sustainable practices, EPA is developing computer-based systems including models, databases, web tools, and web browsers to help communities decide upon approaches that support their desired outcomes. Communities need access to resources that will allow them to achieve their sustainability objectives through intelligent decisions in four key sustainability areas: • Land Use • Buildings and Infrastructure • Transportation • Materials Management (i.e., Municipal Solid Waste [MSW] processing and disposal) The Multi-Sector Sustainability Browser (MSSB) is designed to support sustainable decision-making for communities, local and regional planners, and policy and decision makers. Document is an EPA Technical Report, which is the user manual for the Multi-Sector Sustainability Browser (MSSB) tool. The purpose of the document is to provide basic guidance on use of the tool for users

Suicide ideation of individuals in online social networks.

Suicide explains the largest number of death tolls among Japanese adolescents in their twenties and thirties. Suicide is also a major cause of death for adolescents in many other countries. Although social isolation has been implicated to influence the tendency to suicidal behavior, the impact of social isolation on suicide in the context of explicit social networks of individuals is scarcely explored. To address this question, we examined a large data set obtained from a social networking service dominant in Japan. The social network is composed of a set of friendship ties between pairs of users created by mutual endorsement. We carried out the logistic regression to identify users' characteristics, both related and unrelated to social networks, which contribute to suicide ideation. We defined suicide ideation of a user as the membership to at least one active user-defined community related to suicide. We found that the number of communities to which a user belongs to, the intransitivity (i.e., paucity of triangles including the user), and the fraction of suicidal neighbors in the social network, contributed the most to suicide ideation in this order. Other characteristics including the age and gender contributed little to suicide ideation. We also found qualitatively the same results for depressive symptoms.

Communities of practice are increasingly recognized in rehabilitation as useful knowledge transfer tools; however, little is known about their users. This exploratory study describes the characteristics of participants and non-participants invited to engage in a pediatric rehabilitation virtual community of practice. In addition, we explored virtual community of practice utilization behaviors, engagement predictors, and the impact of strategies designed to foster engagement. Participants' demographics including information-seeking style and organization e-readiness, as well as online platform frequency of use data were collected and analyzed using descriptive, comparative, and predictive statistics. Seventy-four percent of those invited used the virtual community of practice. Users had less years of experience in pediatric rehabilitation than non-users. Among the users, 71% were classified as "lurkers," who engaged through reading content only; while 29% were classified as "posters," editing online content. Predictive factors were not uncovered, however an increased number of forum visits correlated with being a poster, a non-information seeker, an employee of an organization demonstrating e-readiness, and regularly working with children with the virtual community of practice specific condition. User-engagement strategies increased visits to the forum. These findings will assist rehabilitation leaders in leveraging rehabilitation-specific virtual community of practice to improve knowledge transfer and practice in pediatric rehabilitation and disability management. Implications for Rehabilitation Communities of practice are increasingly recognized as useful knowledge transfer tools for rehabilitation professionals and are made more accessible thanks to virtual technologies. Our virtual community of practice was found to be optimized in health care organizations with an electronic culture, when the topic area had daily relevance to its target audience, and was particularly beneficial for those who have limited years of experience in pediatric rehabilitation. A strongly committed, selected leadership team with the technological skills, content expertise, and designated time to maintain the site and to nurture discussion was deemed vital in fostering knowledge exchange in this context. User-focused engagement strategies showed promise in increasing visits to the virtual community of practice. Our study supports the importance of multi-pronged approaches in enhancing health care professional knowledge and skills Findings from this study will assist rehabilitation leaders in optimally leveraging rehabilitation-specific virtual community of practice to improve knowledge transfer in pediatric rehabilitation and disability management.

2009-05-01

Modeling Guru is an on-line knowledge-sharing resource for anyone involved with or interested in NASA's scientific models or High End Computing (HEC) systems. Developed and maintained by the NASA's Software Integration and Visualization Office (SIVO) and the NASA Center for Computational Sciences (NCCS), Modeling Guru's combined forums and knowledge base for research and collaboration is becoming a repository for the accumulated expertise of NASA's scientific modeling and HEC communities. All NASA modelers and associates are encouraged to participate and provide knowledge about the models and systems so that other users may benefit from their experience. Modeling Guru is divided into a hierarchy of communities, each with its own set forums and knowledge base documents. Current modeling communities include those for space science, land and atmospheric dynamics, atmospheric chemistry, and oceanography. In addition, there are communities focused on NCCS systems, HEC tools and libraries, and programming and scripting languages. Anyone may view most of the content on Modeling Guru (available at http://modelingguru.nasa.gov/), but you must log in to post messages and subscribe to community postings. The site offers a full range of "Web 2.0" features, including discussion forums, "wiki" document generation, document uploading, RSS feeds, search tools, blogs, email notification, and "breadcrumb" links. A discussion (a.k.a. forum "thread") is used to post comments, solicit feedback, or ask questions. If marked as a question, SIVO will monitor the thread, and normally respond within a day. Discussions can include embedded images, tables, and formatting through the use of the Rich Text Editor. Also, the user can add "Tags" to their thread to facilitate later searches. The "knowledge base" is comprised of documents that are used to capture and share expertise with others. The default "wiki" document lets users edit within the browser so others can easily collaborate on the same document, even allowing the author to select those who may edit and approve the document. To maintain knowledge integrity, all documents are moderated before they are visible to the public. Modeling Guru, running on Clearspace by Jive Software, has been an active resource to the NASA modeling and HEC communities for more than a year and currently has more than 100 active users. SIVO will soon install live instant messaging support, as well as a user-customizable homepage with social-networking features. In addition, SIVO plans to implement a large dataset/file storage capability so that users can quickly and easily exchange datasets and files with one another. Continued active community participation combined with periodic software updates and improved features will ensure that Modeling Guru remains a vibrant, effective, easy-to-use tool for the NASA scientific community.

This article presents a study that compared participation by elderly individuals living in the community according to primary transportation mode used, and estimated the association between transportation, personal factors, and environmental factors. Participants included 90 adults aged 65 and older (M=76.3 years; SD=7.7). They were classified according to their primary transportation mode: driver, passenger, public transport user, walk, or adapted transport/taxi user. Participation was measured with the Craig Handicap Assessment and Reporting Technique (CHART) and the Nottingham Leisure Questionnaire (NLQ). Overall, results indicated that drivers, public transport users, and walkers had higher participation levels compared to passengers and adapted transport/taxi users. This study suggests that clinicians should consider older adults' use of transportation in an attempt to encourage and maximize their participation.

The LSI community of users is large and varied. To reach all these users as well as potential instrument contributors this document has been organized by measurement parameters of interest such as Leaf Area Index and Land Surface Temperature. These measurement parameters and the data presented in this document are drawn from multiple sources, listed at the end of the document, although the two primary ones are "The Space-Based Global Observing System in 2010 (GOS-2010)" that was compiled for the World Meteorological Organization (WMO) by Bizzarro Bizzarri, and the CEOS Missions, Instruments, and Measurements online database (CEOS MIM). For each measurement parameter the following topics will be discussed: (1) measurement description, (2) applications, (3) measurement spectral bands, and (4) example instruments and mission information. The description of each measurement parameter starts with a definition and includes a graphic displaying the relationships to four general land surface imaging user communities: vegetation, water, earth, and geo-hazards, since the LSI community of users is large and varied. The vegetation community uses LSI data to assess factors related to topics such as agriculture, forest management, crop type, chlorophyll, vegetation land cover, and leaf or canopy differences. The water community analyzes snow and lake cover, water properties such as clarity, and body of water delineation. The earth community focuses on minerals, soils, and sediments. The geo-hazards community is designed to address and aid in emergencies such as volcanic eruptions, forest fires, and large-scale damaging weather-related events.

This paper will explore in detail the effects of context and group dynamics on the development of a multi-level community-based HIV prevention intervention for crack cocaine users in the San Salvador Metropolitan Area, El Salvador. Community partners included residents from marginal communities, service providers from the historic center of San Salvador and research staff from a non-profit organization. The community contexts from which partners came varied considerably and affected structural group dynamics, i.e. who was identified as community partners, their research and organizational capacity, and their ability to represent their communities, with participants from marginal communities most likely to hold community leadership positions and be residents, and those from the center of San Salvador most likely to work in religious organizations dedicated to HIV prevention or feeding indigent drug users. These differences also affected the intervention priorities of different partners. The context of communities changed over time, particularly levels of violence, and affected group dynamics and the intervention developed. Finally, strategies were needed to elicit input from stakeholders under-represented in the community advisory board, in particular active crack users, in order to check the feasibility of the proposed intervention and revise it as necessary. Because El Salvador is a very different context than that in which most CBPR studies have been conducted, our results reveal important contextual factors and their effects on partnerships not often considered in the literature.

The use of crystal methamphetamine (ice) and the associated harms for individuals, families, and communities across Australia has been the subject of growing concern in recent years. The provision of easily accessible, evidence-based, and up-to-date information and resources about crystal methamphetamine for the community is a critical component of an effective public health response. This paper aims to describe the codevelopment process of the Web-based Cracks in the Ice Community Toolkit, which was developed to improve access to evidence-based information and resources about crystal methamphetamine for the Australian community. Development of the Cracks in the Ice Community Toolkit was conducted in collaboration with community members across Australia and with experts working in the addiction field. The iterative process involved the following: (1) consultation with end users, including community members, crystal methamphetamine users, families and friends of someone using crystal methamphetamine, health professionals, and teachers (n=451) via a cross-sectional Web-based survey to understand information needs; (2) content and Web development; and (3) user testing of a beta version of the Web-based toolkit among end users (n=41) and experts (n=10) to evaluate the toolkit's acceptability, relevance, and appeal. Initial end user consultation indicated that the most commonly endorsed reasons for visiting a website about crystal methamphetamine were "to get information for myself" (185/451, 41.0%) and "to find out how to help a friend or a family member" (136/451, 30.2%). Community consultation also revealed the need for simple information about crystal methamphetamine, including what it is, its effects, and when and where to seek help or support. Feedback on a beta version of the toolkit was positive in terms of content, readability, layout, look, and feel. Commonly identified areas for improvement related to increasing the level of engagement and personal connection, improving the ease of navigation, and balancing a "low prevalence of use, yet high impact" message. A total of 9138 users visited the website in the 3 months immediately post launch, and over 25,000 hard-copy Cracks in the Ice booklets and flyers were distributed across Australia. Of these resources, 60.93% (15,525/25,480) were distributed to relevant organizations and mailing list subscribers, and 39.07% (9955/25,480) were ordered directly by individuals, services, and community groups via the Cracks in the Ice website. The codevelopment process resulted in an engaging Web-based resource for the Australian community to access up-to-date and evidence-based resources about crystal methamphetamine. The Cracks in the Ice Community Toolkit provides much-needed information and support for individuals, families, and communities. ©Katrina Elizabeth Champion, Cath Chapman, Nicola Clare Newton, Mary-Ellen Brierley, Lexine Stapinski, Frances Kay-Lambkin, Jack Nagle, Maree Teesson.

2014-01-01

Objective As part of the Heath Information Technology for Economic and Clinical Health (HITECH) Act, the Office of the National Coordinator for Health Information Technology (ONC) implemented its Workforce Development Program, which included initiatives to train health information technology (HIT) professionals in 12 workforce roles, half of them in community colleges. To achieve this, the ONC tasked five universities with established informatics programs with creating curricular materials that could be used by community colleges. The five universities created 20 components that were made available for downloading from the National Training and Dissemination Center (NTDC) website. This paper describes an evaluation of the curricular materials by its intended audience of educators. Methods We measured the quantity of downloads from the NTDC site and administered a survey about the curricular materials to its registered users to determine use patterns and user characteristics. The survey was evaluated using mixed methods. Registered users downloaded nearly half a million units or components from the NTDC website. We surveyed these 9835 registered users. Results 1269 individuals completed all or part of the survey, of whom 339 identified themselves as educators (26.7% of all respondents). This paper addresses the survey responses of educators. Discussion Successful aspects of the curriculum included its breadth, convenience, hands-on and course planning capabilities. Several areas were identified for potential improvement. Conclusions The ONC HIT curriculum met its goals for community college programs and will likely continue to be a valuable resource for the larger informatics community in the future. PMID:23831832

Objective To test the feasibility of implementing ask-advise-refer (AAR) in representative community chain pharmacies serving low socioeconomic areas, and to assess the effectiveness of a multimodal intervention on short-term implementation of AAR. Design Randomized controlled trial Settings Sixteen community chain pharmacies in South-central Wisconsin Intervention A multimodal intervention including: 1) training to implement AAR, 2) workflow integration recommendations, 3) a cessation poster to create awareness, and 4) a support visit. Main outcome measures Number of patrons asked about their tobacco use, number of tobacco users advised to quit, number of quitline cards given, and number of tobacco users enrolled in the quitline. Results As hypothesized, the multimodal intervention significantly predicted the number of patrons asked (estimate=4.84, incidence rate ratios[IRR]=127.2; p<0.001) tobacco users advised (estimate=2.12, IRR=8.33; p<0.01), quitline cards distributed (estimate=1.04, IRR=2.82; p<0.05), and tobacco users enrolled in the quitline (estimate=2.31, IRR=10.13; p<0.001). Conclusion This trial demonstrates the feasibility of implementing AAR in routine community pharmacy practice. This trial also indicates the short-term effectiveness of the intervention in facilitating AAR, implementation in partnership with other public health services and systems. More research is needed to evaluate the generalizability, effectiveness and sustainability of AAR, including factors influencing adoption and the impact on cessation. PMID:22825231

User-generated medical messages on Internet contain extensive information related to adverse drug reactions (ADRs) and are known as valuable resources for post-marketing drug surveillance. The aim of this study was to find an effective method to identify messages related to ADRs automatically from online user reviews. We conducted experiments on online user reviews using different feature set and different classification technique. Firstly, the messages from three communities, allergy community, schizophrenia community and pain management community, were collected, the 3000 messages were annotated. Secondly, the N-gram-based features set and medical domain-specific features set were generated. Thirdly, three classification techniques, SVM, C4.5 and Naïve Bayes, were used to perform classification tasks separately. Finally, we evaluated the performance of different method using different feature set and different classification technique by comparing the metrics including accuracy and F-measure. In terms of accuracy, the accuracy of SVM classifier was higher than 0.8, the accuracy of C4.5 classifier or Naïve Bayes classifier was lower than 0.8; meanwhile, the combination feature sets including n-gram-based feature set and domain-specific feature set consistently outperformed single feature set. In terms of F-measure, the highest F-measure is 0.895 which was achieved by using combination feature sets and a SVM classifier. In all, we can get the best classification performance by using combination feature sets and SVM classifier. By using combination feature sets and SVM classifier, we can get an effective method to identify messages related to ADRs automatically from online user reviews.

Heuristics for Relevancy Ranking of Earth Dataset Search Results

Lynnes, C.; Quinn, P.; Norton, J.

2016-12-01

As the Variety of Earth science datasets increases, science researchers find it more challenging to discover and select the datasets that best fit their needs. The most common way of search providers to address this problem is to rank the datasets returned for a query by their likely relevance to the user. Large web page search engines typically use text matching supplemented with reverse link counts, semantic annotations and user intent modeling. However, this produces uneven results when applied to dataset metadata records simply externalized as a web page. Fortunately, data and search provides have decades of experience in serving data user communities, allowing them to form heuristics that leverage the structure in the metadata together with knowledge about the user community. Some of these heuristics include specific ways of matching the user input to the essential measurements in the dataset and determining overlaps of time range and spatial areas. Heuristics based on the novelty of the datasets can prioritize later, better versions of data over similar predecessors. And knowledge of how different user types and communities use data can be brought to bear in cases where characteristics of the user (discipline, expertise) or their intent (applications, research) can be divined. The Earth Observing System Data and Information System has begun implementing some of these heuristics in the relevancy algorithm of its Common Metadata Repository search engine.

Despite the increase in media attention on “meth cooking” in rural areas of the United States, little is known about rural stimulant use, particularly the criminality associated with stimulant use. Data were collected from community stimulant users in rural Ohio, Arkansas, and Kentucky (N=709). Findings from three logistic regression models indicate that younger stimulant users (x =32.55, SD = 10.35), those with more convictions, and those who used crack frequently were significantly more likely to have been arrested for committing a substance-related crime, a property crime, or another crime in the 6-months before entering the study. Implications include the need for longitudinal studies to further understand rural stimulant use as well as increasing community and corrections-based drug abuse prevention and treatment interventions for stimulant users who live in rural areas.

Since the 1960s, we have witnessed the development and growth of community mental health care that continues to dominate mental health policy and practice. Several high-income countries have implemented community mental health care programmes but for many others, including mostly low- and middle-income countries, it remains an aspiration. Although community mental health care has been positive for many service users, it has also had severe shortcomings. Expectations that it would lead to fuller social integration have not been fulfilled and many service users remain secluded in sheltered or custodial environments with limited social contacts and no prospect of work. Others receive little or no service at all. In today’s complex landscape of increasingly specialised services for people with mental health problems, the number of possible interfaces between services is increasing. Together with existing uneven financing systems and a context of constant change, these interfaces are challenging us to develop effective care pathways adjusted to the needs of service users and their carers. This discussion paper reviews the developments in community mental health care over the recent years and puts forward the concept of “Meta-Community Mental Health Care”. “Meta-Community Mental Health Care” embraces pluralism in understanding and treating psychiatric disorders, acknowledges the complexities of community provision, and reflects the realities and needs of the current era of care.

More than a decade of conflict has weakened the health system in the Democratic Republic of Congo and decreased its ability to respond to the needs of the population. Community scorecards have been conceived as a way to increase accountability and responsiveness of service providers, but there is limited evidence of their effects, particularly in fragile and conflict-affected contexts. This paper describes the implementation of community scorecards within a community-driven reconstruction project in two provinces of eastern Democratic Republic of Congo. Between June 2012 and November 2013, 45 stories of change in the health system were collected from village development committee, health committee, community members (20 men and 18 women) and healthcare providers (n = 7) in 25 sites using the Most Significant Change technique. Stories were analyzed qualitatively for content related to the types and mechanisms of change observed. The most salient changes were related to increased transparency and community participation in health facility management, and improved quality of care. Quality of care included increased access to services, improved patient-provider relationships, improved performance of service providers, and improved maintenance of physical infrastructure. Changes occurred through many different mechanisms including provider actions in response to information, pressure from community representatives, or supervisors; and joint action and improved collaboration by health facility committees and providers. Although it is often assumed that confrontation is a primary mechanism for citizens to change state-provided services, this study demonstrates that healthcare providers may also be motivated to change through other means. Positive experiences of community scorecards can provide a structured space for interface between community members and the health system, allowing users to voice their opinions and preferences and bridge information gaps for both users and frontline healthcare providers. When solutions to problems identified through the scorecard are locally accessible, users and healthcare providers are able to work together to implement mutually acceptable solutions that improve quality of health services, and make them more responsive to users' needs.

'Reaching the hard to reach' - lessons learned from the VCS (voluntary and community Sector). A qualitative study

PubMed Central

2010-01-01

Background The notion 'hard to reach' is a contested and ambiguous term that is commonly used within the spheres of social care and health, especially in discourse around health and social inequalities. There is a need to address health inequalities and to engage in services the marginalized and socially excluded sectors of society. Methods This paper describes a pilot study involving interviews with representatives from eight Voluntary and Community Sector (VCS) organisations. The purpose of the study was to explore the notion of 'hard to reach' and perceptions of the barriers and facilitators to accessing services for 'hard to reach' groups from a voluntary and community sector perspective. Results The 'hard to reach' may include drug users, people living with HIV, people from sexual minority communities, asylum seekers, refugees, people from black and ethnic minority communities, and homeless people although defining the notion of the 'hard to reach' is not straight forward. It may be that certain groups resist engaging in treatment services and are deemed hard to reach by a particular service or from a societal stance. There are a number of potential barriers for people who may try and access services, including people having bad experiences in the past; location and opening times of services and how services are funded and managed. A number of areas of commonality are found in terms of how access to services for 'hard to reach' individuals and groups could be improved including: respectful treatment of service users, establishing trust with service users, offering service flexibility, partnership working with other organisations and harnessing service user involvement. Conclusions If health services are to engage with groups that are deemed 'hard to reach' and marginalised from mainstream health services, the experiences and practices for engagement from within the VCS may serve as useful lessons for service improvement for statutory health services.

Together, community-based participatory research (CBPR), user-centered design (UCD), and health information technology (HIT) offer promising approaches to improve health disparities in low-resource settings. This article describes the application of CBPR and UCD principles to the development of iDecide/Decido, an interactive, tailored, web-based diabetes medication education and decision support tool delivered by community health workers (CHWs) to African American and Latino participants with diabetes in Southwest and Eastside Detroit. The decision aid is offered in English or Spanish and is delivered on an iPad in participants' homes. The overlapping principles of CBPR and UCD used to develop iDecide/Decido include a user-focused or community approach, equitable academic and community partnership in all study phases, an iterative development process that relies on input from all stakeholders, and a program experience that is specified, adapted, and implemented with the target community. Collaboration between community members, researchers, and developers is especially evident in the program's design concept, animations, pictographs, issue cards, goal setting, tailoring, and additional CHW tools. The principles of CBPR and UCD can be successfully applied in developing health information tools that are easy to use and understand, interactive, and target health disparities.

ARM Climate Research Facility: Outreach Tools and Strategies

Roeder, L.; Jundt, R.

2009-12-01

Sponsored by the Department of Energy, the ARM Climate Research Facility is a global scientific user facility for the study of climate change. To publicize progress and achievements and to reach new users, the ACRF uses a variety of Web 2.0 tools and strategies that build off of the program’s comprehensive and well established News Center (www.arm.gov/news). These strategies include: an RSS subscription service for specific news categories; an email “newsletter” distribution to the user community that compiles the latest News Center updates into a short summary with links; and a Facebook page that pulls information from the News Center and links to relevant information in other online venues, including those of our collaborators. The ACRF also interacts with users through field campaign blogs, like Discovery Channel’s EarthLive, to share research experiences from the field. Increasingly, field campaign Wikis are established to help ACRF researchers collaborate during the planning and implementation phases of their field studies and include easy to use logs and image libraries to help record the campaigns. This vital reference information is used in developing outreach material that is shared in highlights, news, and Facebook. Other Web 2.0 tools that ACRF uses include Google Maps to help users visualize facility locations and aircraft flight patterns. Easy-to-use comment boxes are also available on many of the data-related web pages on www.arm.gov to encourage feedback. To provide additional opportunities for increased interaction with the public and user community, future Web 2.0 plans under consideration for ACRF include: evaluating field campaigns for Twitter and microblogging opportunities, adding public discussion forums to research highlight web pages, moving existing photos into albums on FlickR or Facebook, and building online video archives through YouTube.

2017-12-22

Current models of user participation in mental health services were developed within Western culture and thus may not be applicable to Chinese communities. To present a new model of user participation, which emerged from research within a Chinese community, for understanding the processes of and factors influencing user participation in a non-Western culture. Multiple qualitative methods, including focus groups, individual in-depth interviews, and photovoice, were applied within the framework of constructivist grounded theory and collaborative research. Diverging from conceptualizations of user participation with emphasis on civil rights and the individual as a central agent, participants in the study highlighted the interpersonal dynamics between service users and different players affecting the participation intensity and outcomes. They valued a reciprocal relationship with their caregivers in making treatment decisions, cooperated with staff to observe power hierarchies and social harmony, identified the importance of peer support in enabling service engagement and delivery, and emphasized professional facilitation in advancing involvement at the policy level. User participation in Chinese culture embeds dynamic interdependence. The proposed model adds this new dimension to the existing frameworks and calls for attention to the complex local ecology and cultural consistency in realizing user participation.

A New Architecture for Visualization: Open Mission Control Technologies

NASA Technical Reports Server (NTRS)

Trimble, Jay

2017-01-01

Open Mission Control Technologies (MCT) is a new architecture for visualisation of mission data. Driven by requirements for new mission capabilities, including distributed mission operations, access to data anywhere, customization by users, synthesis of multiple data sources, and flexibility for multi-mission adaptation, Open MCT provides users with an integrated customizable environment. Developed at NASAs Ames Research Center (ARC), in collaboration with NASAs Advanced Multimission Operations System (AMMOS) and NASAs Jet Propulsion Laboratory (JPL), Open MCT is getting its first mission use on the Jason 3 Mission, and is also available in the testbed for the Mars 2020 Rover and for development use for NASAs Resource Prospector Lunar Rover. The open source nature of the project provides for use outside of space missions, including open source contributions from a community of users. The defining features of Open MCT for mission users are data integration, end user composition and multiple views. Data integration provides access to mission data across domains in one place, making data such as activities, timelines, telemetry, imagery, event timers and procedures available in one place, without application switching. End user composition provides users with layouts, which act as a canvas to assemble visualisations. Multiple views provide the capability to view the same data in different ways, with live switching of data views in place. Open MCT is browser based, and works on the desktop as well as tablets and phones, providing access to data anywhere. An early use case for mobile data access took place on the Resource Prospector (RP) Mission Distributed Operations Test, in which rover engineers in the field were able to view telemetry on their phones. We envision this capability providing decision support to on console operators from off duty personnel. The plug-in architecture also allows for adaptation for different mission capabilities. Different data types and capabilities may be added or removed using plugins. An API provides a means to write new capabilities and to create data adaptors. Data plugins exist for mission data sources for NASA missions. Adaptors have been written by international and commercial users. Open MCT is open source. Open source enables collaborative development across organizations and also makes the product available outside of the space community, providing a potential source of usage and ideas to drive product design and development. The combination of open source with an Apache 2 license, and distribution on GitHub, has enabled an active community of users and contributors. The spectrum of users for Open MCT is, to our knowledge, unprecedented for mission software. In addition to our NASA users, we have, through open source, had users and inquires on projects ranging from Internet of Things, to radio hobbyists, to farming projects. We have an active community of contributors, enabling a flow of ideas inside and outside of the space community.

Why should we publish Linked Data?

NASA Astrophysics Data System (ADS)

Blower, Jon; Riechert, Maik; Koubarakis, Manolis; Pace, Nino

2016-04-01

We use the Web every day to access information from all kinds of different sources. But the complexity and diversity of scientific data mean that discovering accessing and interpreting data remains a large challenge to researchers, decision-makers and other users. Different sources of useful information on data, algorithms, instruments and publications are scattered around the Web. How can we link all these things together to help users to better understand and exploit earth science data? How can we combine scientific data with other relevant data sources, when standards for describing and sharing data vary so widely between communities? "Linked Data" is a term that describes a set of standards and "best practices" for sharing data on the Web (http://www.w3.org/standards/semanticweb/data). These principles can be summarised as follows: 1. Create unique and persistent identifiers for the important "things" in a community (e.g. datasets, publications, algorithms, instruments). 2. Allow users to "look up" these identifiers on the web to find out more information about them. 3. Make this information machine-readable in a community-neutral format (such as RDF, Resource Description Framework). 4. Within this information, embed links to other things and concepts and say how these are related. 5. Optionally, provide web service interfaces to allow the user to perform sophisticated queries over this information (using a language such as SPARQL). The promise of Linked Data is that, through these techniques, data will be more discoverable, more comprehensible and more usable by different communities, not just the community that produced the data. As a result, many data providers (particularly public-sector institutions) are now publishing data in this way. However, this area is still in its infancy in terms of real-world applications. Data users need guidance and tools to help them use Linked Data. Data providers need reassurance that the investments they are making in publishing Linked Data will result in tangible user benefits. This presentation will address a number of these issues, using real-world experience gathered from four recent European projects: MELODIES (http://melodiesproject.eu), LEO (http://linkedeodata.eu), CHARMe (http://linkedeodata.eu) and TELEIOS (http://www.earthobservatory.eu). These projects have all applied Linked Data techniques in practical, real-world situations involving the use of diverse data (including earth science data) by both industrial and academic users. Specifically, we will: • Identify a set of practical and valuable uses for Linked Data, focusing on areas where Linked Data fills gaps left by other technologies. These uses include: enabling the discovery of earth science data using mass-market search engines, helping users to understand data and its uses, combining data from multiple sources and enabling the annotation of data by users. • Enumerate some common challenges faced by developers of data-driven services who wish to use Linked Data in their applications. • Describe a new suite of tools for managing, processing and visualising Linked Data in earth science applications (including geospatial Linked Data).

User's Manual for the National Water-Quality Assessment Program Invertebrate Data Analysis System (IDAS) Software: Version 3

2003-01-01

The Invertebrate Data Analysis System (IDAS) software provides an accurate, consistent, and efficient mechanism for analyzing invertebrate data collected as part of the National Water-Quality Assessment Program and stored in the Biological Transactional Database (Bio-TDB). The IDAS software is a stand-alone program for personal computers that run Microsoft (MS) Windows?. It allows users to read data downloaded from Bio-TDB and stored either as MS Excel? or MS Access? files. The program consists of five modules. The Edit Data module allows the user to subset, combine, delete, and summarize community data. The Data Preparation module allows the user to select the type(s) of sample(s) to process, calculate densities, delete taxa based on laboratory processing notes, combine lifestages or keep them separate, select a lowest taxonomic level for analysis, delete rare taxa, and resolve taxonomic ambiguities. The Calculate Community Metrics module allows the user to calculate over 130 community metrics, including metrics based on organism tolerances and functional feeding groups. The Calculate Diversities and Similarities module allows the user to calculate nine diversity and eight similarity indices. The Data export module allows the user to export data to other software packages and produce tables of community data that can be imported into spreadsheet and word-processing programs. Though the IDAS program was developed to process invertebrate data downloaded from USGS databases, it will work with other data sets that are converted to the USGS (Bio-TDB) format. Consequently, the data manipulation, analysis, and export procedures provided by the IDAS program can be used by anyone involved in using benthic macroinvertebrates in applied or basic research.

The goals were to evaluate the use of touchscreen computer kiosks, containing only child health-promoting information, in urban, low-income, community settings and to characterize the users of these kiosks. Three user-driven touchscreen computer kiosks were placed in low-income urban locations in Seattle, Washington, from March 2005 to October 2005. The locations included a public library, a Department of Motor Vehicles office, and a McDonald's restaurant. Users selected age-appropriate modules with prevention information and screening tools. Users entered the age of the child and were presented with age-appropriate modules. On exiting, users were asked to rate their experience and to provide basic demographic data. In total, there were 1846 kiosk sessions. Almost one half occurred at McDonald's. Seventy-eight percent of users identified themselves as first-time users. Users sought information for children of all ages. Sixty-one percent of first-time users explored 1 module. First-time users were most interested in television/media use (16%), smoke exposure (14%), attention-deficit/hyperactivity disorder screening (12%), and asthma assessment (11%). At-risk children were identified in 52% of sessions. Eighty-seven percent of first-time users who completed the asthma assessment had children whose asthma was uncontrolled. Twenty-eight percent of users responded to > or = 1 question on the exit survey. Of those, 48% had less than a high school education, and 26% had never used the Internet. Approximately one half found the kiosk easy to use (57%) and the information easy to understand (55%); 66% said there was at least some new information. Fifty-five percent planned to try some of the things they had learned, and 49% intended to talk to their child's doctor about what they had learned. User-driven computer kiosks were used in community settings to obtain child health information. Users found the kiosks easy to use. Additional study on improving use and understanding the impact is needed.

Background In order to adapt to societal changes, healthcare systems need to switch from a disease orientation to a patient-centered approach. Virtual patient networks are a promising tool to favor this switch and much can be learned from the open and user innovation literature where the involvement of online user communities in the innovation process is well-documented. Objectives The objectives of this study were 1) to describe the use of online communities as a tool to capture and harness innovative ideas of end users or consumers; and 2) to point to the potential value and challenges of these virtual platforms to function as a tool to inform and promote patient-centered care in the context of chronic health conditions. Methods A scoping review was conducted. A total of seven databases were searched for scientific articles published in English between 1995 and 2014. The search strategy was refined through an iterative process. Results A total of 144 studies were included in the review. Studies were coded inductively according to their research focus to identify groupings of papers. The first set of studies focused on the interplay of factors related to user roles, motivations, and behaviors that shape the innovation process within online communities. Studies of the second set examined the role of firms in online user innovation initiatives, identifying different organizational strategies and challenges. The third set of studies focused on the idea selection process and measures of success with respect to online user innovation initiatives. Finally, the findings from the review are presented in the light of the particularities and challenges discussed in current healthcare research. Conclusion The present paper highlights the potential of virtual patient communities to inform and promote patient-centered care, describes the key challenges involved in this process, and makes recommendations on how to address them.

This report explores ways to meet the transportation needs of elderly and disabled people in a number of communities north of Boston, Massachusetts. The study uses a process which appears to have broad applicability in other jurisdictions. It examines the demographics in the communities involved first, projecting them into the future. It then conducts a detailed inventory of transportation services, including services for the general public and special users provided by the local transit authorities, private nonprofit services for special users, and privately provided services. Conducting a community-by-community review, the process notes overall levels of demand, concentrations of special usersmore » and their destinations, and the location of transportation routes relative to them. It then recommends new services or alterations to existing services to remedy present or future mismatches. The report should be of interest to transportation planners in communities of all sizes.« less

Unidata's mission is to provide the data services, tools, and cyberinfrastructure leadership that advance Earth system science, enhance educational opportunities, and broaden participation. The Unidata community has grown from around 250 individual participants in the early years to tens of thousands of users in over 150 countries. Today, Unidata's products and services are used on every continent and by every sector of the geoscience enterprise: universities, government agencies, private sector, and other non-governmental organizations. Certain traits and ethos are shared by and common to most successful organizations. They include a healthy organizational culture grounded by some core values and guiding principles. In that environment, there is an implicit awareness of the connection between mission of an organization, its values, and its day-to-day activities, and behaviours of a passionate staff. Distinguishing characteristics include: vigorous engagement of the community served by those organizations backed by strong and active governance, unwavering commitment to seek input and feedback from users, and trust of those users, earned over many years through consistent, dependable, and high-quality service. Meanwhile, changing data volumes and standards, new computing power, and expanding scientific questions sound continue to shape the geoscience community. These issues were the drivers for founding Unidata, a cornerstone data facility, in 1984. Advances in geoscience occur at the junction of community, science, and technology and this submission will feature lessons from Unidata's thirty year history operating at this nexus. Specifically, this presentation will feature guiding principles for the program, governance mechanisms, and approaches for balancing science and technology in a community-driven program.

The National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), part of the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder, will archive and distribute all primary data sets collected during the NASA SnowEx campaigns. NSIDC DAAC's overarching goal for SnowEx data management is to steward the diverse SnowEx data sets to provide a reliable long-term archive, to enable effective data discovery, retrieval, and usage, and to support end user engagement. This goal will be achieved though coordination and collaboration with SnowEx project management and investigators. NSIDC DAAC's core functions for SnowEx data management include: Data Creation: Advise investigators on data formats and structure as well as metadata creation and content to enable preservation, usability, and discoverability. Data Documentation: Develop comprehensive data set documentation describing the instruments, data collection and derivation methods, and data file contents. Data Distribution: Provide discovery and access through NSIDC and NASA data portals to make SnowEx data available to a broad user community Data & User Support: Assist user communities with the selection and usage of SnowEx data products. In an effort to educate and broaden the SnowEx user community, we will present an overview of the SnowEx data products, tools, and services which will be available at the NSIDC DAAC. We hope to gain further insight into how the DAAC can enable the user community to seamlessly and effectively utilize SnowEx data in their research and applications.

This study was designed to develop an evidence- and community based falls prevention program -- Tai Chi: Moving for Better Balance. A mixed qualitative and quantitative approach was used to develop a package of materials for program implementation and evaluation. The developmental work was conducted in 2 communities in the Pacific Northwest. Participants included a panel of experts, senior service program managers or activity coordinators, and older adults. Outcome measures involved program feasibility and satisfaction. Through an iterative process, a program package was developed. The package contained an implementation plan and class training materials (ie, instructor's manual, videotape, and user's guidebook). Pilot testing of program materials showed that the content was appropriate for the targeted users (community-living older adults) and providers (local senior service organizations). A feasibility survey indicated interest and support from users and providers for program implementation. A 2-week pilot evaluation showed that the program implementation was feasible and evidenced good class attendance, high participant satisfaction, and interest in continuing Tai Chi. The package of materials developed in this study provides a solid foundation for larger scale implementation and evaluation of the program in community settings.

Hydrology Applications of the GRACE missions

NASA Astrophysics Data System (ADS)

Srinivasan, M. M.; Ivins, E. R.; Jasinski, M. F.

2014-12-01

NASA and their German space agency partners have a rich history of global gravity observations beginning with the launch of the Gravity Recovery And Climate Experiment (GRACE) in 2002. The science goals of the mission include providing monthly maps of variations in the gravity field, where the major time-varying signal is due to water motion in the Earth system. GRACE has a unique ability to observe the mass flux of water movement at monthly time scales. The hydrology applications of the GRACE mission include measurements of seasonal storage of surface and subsurface water and evapotranspiration at the land-ocean-atmosphere boundary. These variables are invaluable for improved modeling and prediction of Earth system processes. Other mission-critical science objectives include measurements that are a key component of NASA's ongoing climate measuring capabilities. Successful strategies to enhance science and practical applications of the proposed GRACE-Follow On (GRACE-FO) mission, scheduled to launch in 2017, will require engaging with and facilitating between representatives in the science, societal applications, and mission planning communities. NASA's Applied Sciences Program is supporting collaboration on an applied approach to identifying communities of potential and of practice in order to identify and promote the societal benefits of these and future gravity missions. The objective is to engage applications-oriented users and organizations and enable them to envision possible applications and end-user needs as a way to increase the benefits of these missions to the nations. The focus of activities for this applications program include; engaging the science community in order to identify applications and current and potential data users, developing a written Applications Plan, conducting workshops and user tutorials, providing ready access to information via web pages, developing databases of key and interested users/scientists, creating printed materials (posters, brochures) that identify key capabilities and applications of the missions and data, and participation in key science meetings and decision support processes.

Social and place-focused communities in location-based online social networks

NASA Astrophysics Data System (ADS)

Brown, Chloë; Nicosia, Vincenzo; Scellato, Salvatore; Noulas, Anastasios; Mascolo, Cecilia

2013-06-01

Thanks to widely available, cheap Internet access and the ubiquity of smartphones, millions of people around the world now use online location-based social networking services. Understanding the structural properties of these systems and their dependence upon users' habits and mobility has many potential applications, including resource recommendation and link prediction. Here, we construct and characterise social and place-focused graphs by using longitudinal information about declared social relationships and about users' visits to physical places collected from a popular online location-based social service. We show that although the social and place-focused graphs are constructed from the same data set, they have quite different structural properties. We find that the social and location-focused graphs have different global and meso-scale structure, and in particular that social and place-focused communities have negligible overlap. Consequently, group inference based on community detection performed on the social graph alone fails to isolate place-focused groups, even though these do exist in the network. By studying the evolution of tie structure within communities, we show that the time period over which location data are aggregated has a substantial impact on the stability of place-focused communities, and that information about place-based groups may be more useful for user-centric applications than that obtained from the analysis of social communities alone.

The design and implementation of a national computing system and data grid has become a reachable goal from both the computer science and computational science point of view. A distributed infrastructure capable of sophisticated computational functions can bring many benefits to scientific work, but poses many challenges, both technical and socio-political. Technical challenges include having basic software tools, higher-level services, functioning and pervasive security, and standards, while socio-political issues include building a user community, adding incentives for sites to be part of a user-centric environment, and educating funding sources about the needs of this community. This paper details the areasmore » relating to Grid research that we feel still need to be addressed to fully leverage the advantages of the Grid.« less

How Social Communications Influence Advertising Perception and Response in Online Communities?

PubMed

Zeng, Fue; Tao, Ran; Yang, Yanwu; Xie, Tingting

2017-01-01

This research aims to explore how social communications of online communities affect users' perception and responses toward social media advertising. We developed a conceptual model based on the SBT, encapsulating 9 constructs and 10 hypothesis extracted from the extant social media advertising literature. Our research outcome proves that social communications can effectively boost users' behaviors to be in accordance with an online social community, thus facilitate their acceptance and responses toward social media advertising, with users' group intention as an intervening factor. From an operational standpoint, it's an effective way to build and maintain social bonds between users and the community by boosting social communications, supporting fluent interpersonal communications. In addition, managers of an online community should elaborate on users' group intentions to increase users' advertising acceptance and response.

The Access To Space (ATS) Group at NASA's Goddard Space Flight Center (GSFC) supports the science and technology community at GSFC by facilitating frequent and affordable opportunities for access to space. Through partnerships established with access mode suppliers, the ATS Group has developed an interactive Mission Design web site. The ATS web site provides both the information and the tools necessary to assist mission planners in selecting and planning their ride to space. This includes the evaluation of single payloads vs. ride-sharing opportunities to reduce the cost of access to space. Features of this site include the following: (1) Mission Database. Our mission database contains a listing of missions ranging from proposed missions to manifested. Missions can be entered by our user community through data input tools. Data is then accessed by users through various search engines: orbit parameters, ride-share opportunities, spacecraft parameters, other mission notes, launch vehicle, and contact information. (2) Launch Vehicle Toolboxes. The launch vehicle toolboxes provide the user a full range of information on vehicle classes and individual configurations. Topics include: general information, environments, performance, payload interface, available volume, and launch sites.

Predicting mosaics and wildlife diversity resulting from fire disturbance to a forest ecosystem

NASA Astrophysics Data System (ADS)

Potter, Meredith W.; Kessell, Stephen R.

1980-05-01

A model for predicting community mosaics and wildlife diversity resulting from fire disturbance to a forest ecosystem is presented. It applies an algorithm that delineates the size and shape of each patch from grid-based input data and calculates standard diversity measures for the entire mosaic of community patches and their included animal species. The user can print these diversity calculations, maps of the current community-type-age-class mosaic, and maps of habitat utilization by each animal species. Furthermore, the user can print estimates of changes in each resulting from natural disturbance. Although data and resolution level independent, the model is demonstrated and tested with data from the Lewis and Clark National Forest in Montana.

In the mood: the dynamics of collective sentiments on Twitter

Charlton, Nathaniel; Singleton, Colin; Greetham, Danica Vukadinović

2016-01-01

We study the relationship between the sentiment levels of Twitter users and the evolving network structure that the users created by @-mentioning each other. We use a large dataset of tweets to which we apply three sentiment scoring algorithms, including the open source SentiStrength program. Specifically we make three contributions. Firstly, we find that people who have potentially the largest communication reach (according to a dynamic centrality measure) use sentiment differently than the average user: for example, they use positive sentiment more often and negative sentiment less often. Secondly, we find that when we follow structurally stable Twitter communities over a period of months, their sentiment levels are also stable, and sudden changes in community sentiment from one day to the next can in most cases be traced to external events affecting the community. Thirdly, based on our findings, we create and calibrate a simple agent-based model that is capable of reproducing measures of emotive response comparable with those obtained from our empirical dataset.

Peer delivered, social oriented HIV prevention intervention designs are increasingly popular for addressing broader contexts of health risk beyond a focus on individual factors. Such interventions have the potential to affect multiple social levels of risk and change, including at the individual, network, and community levels, and reflect social ecological principles of interaction across social levels over time. The iterative and feedback dynamic generated by this multi-level effect increases the likelihood for sustained health improvement initiated by those trained to deliver the peer intervention. The Risk Avoidance Partnership (RAP), conducted with heroin and cocaine/crack users in Hartford, Connecticut, exemplified this intervention design and illustrated the multi-level effect on drug users' risk and harm reduction at the individual level, the social network level, and the larger community level. Implications of the RAP program for designing effective prevention programs and for analyzing long-term change to reduce HIV transmission among high-risk groups are discussed from this ecological and multi-level intervention perspective.

Community Structure in Online Collegiate Social Networks

Traud, Amanda; Kelsic, Eric; Mucha, Peter; Porter, Mason

2009-03-01

Online social networking sites have become increasingly popular with college students. The networks we studied are defined through ``friendships'' indicated by Facebook users from UNC, Oklahoma, Caltech, Georgetown, and Princeton. We apply the tools of network science to study the Facebook networks from these five different universities at a single point in time. We investigate each single-institution network's community structure, which we obtain through partitioning the graph using an eigenvector method. We use both graphical and quantitative tools, including pair-counting methods, which we interpret through statistical analysis and permutation tests to measure the correlations between the network communities and a set of characteristics given by each user (residence, class year, major, and high school). We also analyze the single gender subsets of these networks, and the impact of missing demographical data. Our study allows us to compare the online social networks for the five schools as well as infer differences in offline social interactions. At the schools studied, we were able to define which characteristics of the Facebook users correlate best with friendships.

To develop predictive models to allocate patients into frequent and low service users groups within the Italian Community-based Mental Health Services (CMHSs). To allocate frequent users to different packages of care, identifying the costs of these packages. Socio-demographic and clinical data and GAF scores at baseline were collected for 1250 users attending five CMHSs. All psychiatric contacts made by these patients during six months were recorded. A logistic regression identified frequent service users predictive variables. Multinomial logistic regression identified variables able to predict the most appropriate package of care. A cost function was utilised to estimate costs. Frequent service users were 49%, using nearly 90% of all contacts. The model classified correctly 80% of users in the frequent and low users groups. Three packages of care were identified: Basic Community Treatment (4,133 Euro per six months); Intensive Community Treatment (6,180 Euro) and Rehabilitative Community Treatment (11,984 Euro) for 83%, 6% and 11% of frequent service users respectively. The model was found to be accurate for 85% of users. It is possible to develop predictive models to identify frequent service users and to assign them to pre-defined packages of care, and to use these models to inform the funding of psychiatric care.

Community Identity and User Engagement in a Multi-Community Landscape.

A community's identity defines and shapes its internal dynamics. Our current understanding of this interplay is mostly limited to glimpses gathered from isolated studies of individual communities. In this work we provide a systematic exploration of the nature of this relation across a wide variety of online communities. To this end we introduce a quantitative, language-based typology reflecting two key aspects of a community's identity: how distinctive , and how temporally dynamic it is. By mapping almost 300 Reddit communities into the landscape induced by this typology, we reveal regularities in how patterns of user engagement vary with the characteristics of a community. Our results suggest that the way new and existing users engage with a community depends strongly and systematically on the nature of the collective identity it fosters, in ways that are highly consequential to community maintainers. For example, communities with distinctive and highly dynamic identities are more likely to retain their users. However, such niche communities also exhibit much larger acculturation gaps between existing users and newcomers, which potentially hinder the integration of the latter. More generally, our methodology reveals differences in how various social phenomena manifest across communities, and shows that structuring the multi-community landscape can lead to a better understanding of the systematic nature of this diversity.

The characteristics and experience of community food program users in arctic Canada: a case study from Iqaluit, Nunavut

PubMed Central

2012-01-01

Background Community food programs (CFPs), including soup kitchens and food banks, are a recent development in larger settlements in the Canadian Arctic. Our understanding of utilization of these programs is limited as food systems research has not studied the marginalised and transient populations using CFPs, constraining service planning for some of the most vulnerable community members. This paper reports on a baseline study conducted with users of CFPs in Iqaluit, Nunavut, to identify and characterize utilization and document their food security experience. Methods Open ended interviews and a fixed-choice survey on a census (n = 94) were conducted with of users of the food bank, soup kitchen, and friendship centre over a 1 month period, along with key informant interviews. Results Users of CFPs are more likely to be Inuit, be unemployed, and have not completed high school compared to the general Iqaluit population, while also reporting high dependence on social assistance, low household income, and an absence of hunters in the household. The majority report using CFPs for over a year and on a regular basis. Conclusions The inability of users to obtain sufficient food must be understood in the context of socio-economic transformations that have affected Inuit society over the last half century as former semi-nomadic hunting groups were resettled into permanent settlements. The resulting livelihood changes profoundly affected how food is produced, processed, distributed, and consumed, and the socio-cultural relationships surrounding such activities. Consequences have included the rising importance of material resources for food access, the weakening of social safety mechanisms through which more vulnerable community members would have traditionally been supported, and acculturative stress. Addressing these broader challenges is essential for food policy, yet CFPs also have an essential role in providing for those who would otherwise have limited food access. PMID:22720722

ISCE: A Modular, Reusable Library for Scalable SAR/InSAR Processing

NASA Astrophysics Data System (ADS)

Agram, P. S.; Lavalle, M.; Gurrola, E. M.; Sacco, G. F.; Rosen, P. A.

2016-12-01

Traditional community SAR/InSAR processing software tools have primarily focused on differential interferometry and Solid Earth applications. The InSAR Scientific Computing Environment (ISCE) was specifically designed to support the Earth Sciences user community as well as large scale operational processing tasks, thanks to its two-layered (Python+C/Fortran) architecture and modular framework. ISCE is freely distributed as a source tarball, allowing advanced users to modify and extend it for their research purposes and developing exploratory applications, while providing a relatively simple user interface for novice users to perform routine data analysis efficiently. Modular design of the ISCE library also enables easier development of applications to address the needs of Ecosystems, Cryosphere and Disaster Response communities in addition to the traditional Solid Earth applications. In this talk, we would like to emphasize the broader purview of the ISCE library and some of its unique features that sets it apart from other freely available community software like GMTSAR and DORIS, including: Support for multiple geometry regimes - Native Doppler (ALOS-1) as well Zero Doppler (ESA missions) systems. Support for data acquired by airborne platforms - e.g, JPL's UAVSAR and AirMOSS, DLR's F-SAR. Radiometric Terrain Correction - Auxiliary output layers from the geometry modules include projection angles, incidence angles, shadow-layover masks. Dense pixel offsets - Parallelized amplitude cross correlation for cryosphere / ionospheric correction applications. Rubber sheeting - Pixel-by-pixel offsets fields for resampling slave imagery for geometric co-registration/ ionospheric corrections. Preliminary Tandem-X processing support - Bistatic geometry modules. Extensibility to support other non-Solid Earth missions - Modules can be directly adopted for use with other SAR missions, e.g., SWOT. Preliminary support for multi-dimensional data products- multi-polarization, multi-frequency, multi-temporal, multi-baseline stacks via the PLANT and GIAnT toolboxes. Rapid prototyping - Geometry manipulation functionality at the python level allows users to prototype and test processing modules at the interpreter level before optimal implementation in C/C++/Fortran.

Living in supportive housing for people with serious mental illness: a paradoxical everyday life.

PubMed

Bengtsson-Tops, Anita; Ericsson, Ulf; Ehliasson, Kent

2014-10-01

Since the closure of large psychiatric institutions, various types of community-based supportive housing for people with serious mental illness (SMI) have been developed. There is currently limited knowledge about users' experiences of living in supportive housing. The aim of the present study was to describe user experiences of living in supportive housing for people with SMI. Twenty-nine people living in such facilities participated in open, qualitative interviews. Data were subjected to latent content analysis. Three main themes emerged from this analysis: (i) having a nest, which included the subthemes of a place to rest and having someone to attach to; (ii) being part of a group, with the subthemes of being brought together and a community spirit; and (iii) leading an oppressive life, including the subthemes of questioning one's identity, sense of inequality, and a life of gloom. It could be concluded that user experiences of living in supportive housing are complex and paradoxical. In order to provide supportive housing, staff need to recognize and work within social group processes, and perform continual and structural evaluations of users' social and emotional needs. © 2014 Australian College of Mental Health Nurses Inc.

Improving data discovery and usability through commentary and user feedback: the CHARMe project

Alegre, R.; Blower, J. D.

Earth science datasets are highly diverse. Users of these datasets are similarly varied, ranging from research scientists through industrial users to government decision- and policy-makers. It is very important for these users to understand the applicability of any dataset to their particular problem so that they can select the most appropriate data sources for their needs. Although data providers often provide rich supporting information in the form of metadata, typically this information does not include community usage information that can help other users judge fitness-for-purpose.The CHARMe project (http://www.charme.org.uk) is filling this gap by developing a system for sharing "commentary metadata". These are annotations that are generated and shared by the user community and include: Links between publications and datasets. The CHARMe system can record information about why a particular dataset was used (e.g. the paper may describe the dataset, it may use the dataset as a source, or it may be publishing results of a dataset assessment). These publications may appear in the peer-reviewed literature, or may be technical reports, websites or blog posts. Free-text comments supplied by the user. Provenance information, including links between datasets and descriptions of processing algorithms and sensors. External events that may affect data quality (e.g. large volcanic eruptions or El Niño events); we call these "significant events". Data quality information, e.g. system maturity indices. Commentary information can be linked to anything that can be uniquely identified (e.g. a dataset with a DOI or a persistent web address). It is also possible to associate commentary with particular subsets of datasets, for example to highlight an issue that is confined to a particular geographic region. We will demonstrate tools that show these capabilities in action, showing how users can apply commentary information during data discovery, visualization and analysis. The CHARMe project has implemented a set of open-source tools to create, store and explore commentary information, using open Web standards. In this presentation we will describe the application of the CHARMe system to the particular case of the climate data community; however the techniques and technologies are generic and can be applied in many fields.

Twitter tweets were sampled from July 2016 to September 2016 using #hearing, #hearingloss, #deaf, #hearingimpairment, #hardofhearing, #deafness, #hearingmatters, #hearinghealth, and #hearingimpaired tags. User and Twitter social community metrics were examined including temporal trends, tweet content, user activity, tweet reach, and an analysis of the tweets' social network. We identified and analyzed 49,208 tweets from July 2016 to September 2016 with tags relevant to hearing loss. Of the 100 most active Twitter accounts, organizations owned 67% compared to 33% owned by individuals. Commercial/for profit and informational organizations were the most common organization account owners (26% and 16%, respectively). Five unique tweets were identified as each having a reach of over 100,000 Twitter users, with the greatest reach exceeding 250,000 users. Temporal analysis identified marked retweet outliers (>300 retweets per hour) that corresponded with a widely publicized event involving the dismissal of a deaf employee from a fast-food chain store. Twitter accounts owned by organizations outnumbered individual accounts, and commercial/for profit user accounts were the most frequently active organization account type. Tweets pertaining to hearing loss may have a broad reach to a large community base. Analyses of social media use can be helpful in discovering issues of interest to the hearing loss community, as well as determining which users and organizations are dominating social network conversations.

Flexible, ready access to community health assessment data is a feature of innovative Web-based data query systems. An example is VistaPHw, which provides access to Washington state data and statistics used in community health assessment. Because of its flexible analysis options, VistaPHw customizes local, population-based results to be relevant to public health decision-making. The advantages of two innovations, dynamic grouping and the Custom Data Module, are described. Dynamic grouping permits the creation of user-defined aggregations of geographic areas, age groups, race categories, and years. Standard VistaPHw measures such as rates, confidence intervals, and other statistics may then be calculated for the new groups. Dynamic grouping has provided data for major, successful grant proposals, building partnerships with local governments and organizations, and informing program planning for community organizations. The Custom Data Module allows users to prepare virtually any dataset so it may be analyzed in VistaPHw. Uses for this module may include datasets too sensitive to be placed on a Web server or datasets that are not standardized across the state. Limitations and other system needs are also discussed.

Nowadays social network services have been popularly used in electronic commerce systems. Users on the social network can develop different relationships based on their common interests and activities. In order to promote the business, it is interesting to explore hidden relationships among users developed on the social network. Such knowledge can be used to locate target users for different advertisements and to provide effective product recommendations. In this paper, we define and study a novel community detection problem that is to discover the hidden community structure in large social networks based on their common interests. We observe that the users typically pay more attention to those users who share similar interests, which enable a way to partition the users into different communities according to their common interests. We propose two algorithms to detect influential communities using common interests in large social networks efficiently and effectively. We conduct our experimental evaluation using a data set from Epinions, which demonstrates that our method achieves 4-11.8% accuracy improvement over the state-of-the-art method.

Community outreach: from measuring the difference to making a difference with health information*

PubMed Central

Ottoson, Judith M.; Green, Lawrence W.

2005-01-01

Background: Community-based outreach seeks to move libraries beyond their traditional institutional boundaries to improve both access to and effectiveness of health information. The evaluation of such outreach needs to involve the community in assessing the program's process and outcomes. Purpose: Evaluation of community-based library outreach programs benefits from a participatory approach. To explain this premise of the paper, three components of evaluation theory are paired with relevant participatory strategies. Concepts: The first component of evaluation theory is also a standard of program evaluation: use. Evaluation is intended to be useful for stakeholders to make decisions. A useful evaluation is credible, timely, and of adequate scope. Participatory approaches to increase use of evaluation findings include engaging end users early in planning the program itself and in deciding on the outcomes of the evaluation. A second component of evaluation theory seeks to understand what is being evaluated, such as specific aspects of outreach programs. A transparent understanding of the ways outreach achieves intended goals, its activities and linkages, and the context in which it operates precedes any attempt to measure it. Participatory approaches to evaluating outreach include having end users, such as health practitioners in other community-based organizations, identify what components of the outreach program are most important to their work. A third component of evaluation theory is concerned with the process by which value is placed on outreach. What will count as outreach success or failure? Who decides? Participatory approaches to valuing include assuring end-user representation in the formulation of evaluation questions and in the interpretation of evaluation results. Conclusions: The evaluation of community-based outreach is a complex process that is not made easier by a participatory approach. Nevertheless, a participatory approach is more likely to make the evaluation findings useful, ensure that program knowledge is shared, and make outreach valuing transparent. PMID:16239958

Low vision and mobility scooters: the experiences of individuals with low vision who use mobility scooters.

McMullan, Keri S; Butler, Mary

2018-05-09

Older adults with low vision are a growing population with rehabilitation needs including support with community mobility to enable community participation. Some older adults with low vision choose to use mobility scooters to mobilize within their community, but there is limited research about the use by people with low vision. This paper describes a pilot study and asks the question: what are the experiences of persons with low vision who use mobility scooters? This study gathered the experiences of four participants with low vision, aged 51 and over, who regularly use mobility scooters. Diverse methods were used including a go-along, a semi-structured interview and a new measure of functional vision for mobility called the vision-related outcomes in orientation and mobility (VROOM). Four themes were found to describe experiences: autonomy and well-being, accessibility, community interactions and self-regulation. Discussion and implications: This study was a pilot for a larger study examining self-regulation in scooter users. However, as roles emerge for health professionals and scooters, the findings also provide evidence to inform practice, because it demonstrates the complex meaning and influences on performance involved in low vision mobility scooter use. Implications for rehabilitation Scooter use supports autonomy and well-being and community connections for individuals with both mobility and visual impairments. Low vision scooter users demonstrate self-regulation of their scooter use to manage both their visual and environmental limitations. Issues of accessibility experienced by this sample affect a wider community of footpath users, emphasizing the need for councils to address inadequate infrastructure. Rehabilitators can support their low vision clients' scooter use by acknowledging issues of accessibility and promoting self-regulation strategies to manage risks and barriers.

Center for Integrated Nanotechnologies 2011 Annual Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sanders, Antonya

We are pleased to share with you this 2011 edition of the Annual Report from the Center for Integrated Nanotechnologies (CINT) and the growing excitement we feel around cementing our brand as a leader in integration nanoscience. This can be seen most readily in the momentum we have achieved in our signature Integration Focus Activities (IFAs). These efforts unite our scientists across our four scientific Thrust areas with our users to concentrate research on larger-scale nanoscience integration challenges for specific classes of nanomaterials, systems, and phenomena. All three of our current IFAs (p. 10) now have a full head ofmore » steam, and nearly 30% of our current user projects map in some meaningful way to one of these IFAs. As part of our redoubled effort to increase our industrial user base, we are also looking to leverage these IFAs to build a stronger link to and spur recruitment within our industrial user community. We believe that the IFAs are a natural community-building tool with an intrinsic value proposition for industry; an R&D pipeline that can lead to more mature, more commercially well-positioned technologies. Finally, as nanoscience and nanotechnology are maturing, we as a research community are beginning to see our efforts extend in many exciting new directions. Our focus on nanoscience integration positions us very well to capitalize on new opportunities including the emerging Mesoscale Initiative within the DOE Office of Science. Many aspects of mesoscale science are embodied in the integration of nanoscale building blocks. We are equally proud of our continuing strong performance in support of our user program. We have fully transitioned to our new user proposal database providing enhanced convenience and flexibility for proposal submission and review. In our two regular proposal calls this year we received a total of 225 proposals, an increase of 10% over our 2010 performance. Our official count on number of users for the period remains at {approx}350 and continues to reflect full engagement of our scientific staff. We are also seeing a steady increase in our industrial user base, with the number of industrial proposals (including Rapid Access proposals) doubling in 2011. We attribute this in part of our outreach efforts including our focused industrial session in each of our past two annual User Conferences. The Center for Integrated Nanotechnologies (CINT) is a Department of Energy/Office of Science Nanoscale Science Research Center (NSRC) operating as a national user facility devoted to establishing the scientific principles that govern the design, performance, and integration of nanoscale materials. Jointly operated by Los Alamos and Sandia National Laboratories, CINT explores the continuum from scientific discovery to use-inspired research, with a focus on the integration of nanoscale materials and structures to achieve new properties and performance and their incorporation into the micro- and macro worlds. Through its Core Facility at Sandia National Laboratories and its Gateway Facility at Los Alamos National Laboratory, CINT provides open access to tools and expertise needed to explore the continuum from scientific discovery to the integration of nanostructures into the micro- and macro worlds. In its overall operations, CINT strives to achieve the following goals common to all Nanoscale Science Research Centers: (1) Conduct forefront research in nanoscale science; (2) Operate as a user facility for scientific research; (3) Provide user access to the relevant BES-supported expertise and capabilities at the host national laboratory; and (4) Leverage other relevant national laboratory capabilities to enhance scientific opportunities for the nanoscience user community. These additional goals are specific to the unique CINT mission: (5) Establish and lead a scientific community dedicated to solving nanoscale science integration challenges; and (6) Create a single user facility program that combines expertise and facilities at both Los Alamos and Sandia National Laboratories. The CINT user program provides the international scientific community with open access to world-class scientific staff and state-of-the-art facilities for theory and simulation, nanomaterials synthesis and characterization, and unique capabilities for nanoscale materials integration, from the level of nanoscale synthesis to the fabrication of micro- and macroscale structures and devices. The staff of CINT includes laboratory scientists, postdocs and technical support staff who are leaders in the nanoscience research programs in CINT scientific thrust areas: (1) Nanoscale Electronics and Mechanics, (2) Nanophotonics and Optical Nanomaterials, (3) Soft, Biological and Composite Nanomaterials, and (4) Theory and Simulation of Nanoscale Phenomena.« less

Although some articles have analysed the definitions of health and health promotion from the perspective of health-care users and health care professionals, no published studies include the simultaneous participation of health-care users, primary health care professionals and key community informants. Understanding the perception of health and health promotion amongst these different stakeholders is crucial for the design and implementation of successful, equitable and sustainable measures that improve the health and wellbeing of populations. Furthermore, the identification of different health assets and deficits by the different informants will generate new evidence to promote healthy behaviours, improve community health and wellbeing and reduce preventable inequalities. The objective of this study is to explore the concept of health and health promotion and to compare health assets and deficits as identified by health-care users, key community informants and primary health care workers with the ultimate purpose to collect the necessary data for the design and implementation of a successful health promotion intervention. A descriptive-interpretive qualitative research was conducted with 276 participants from 14 primary care centres of 7 Spanish regions. Theoretical sampling was used for selection. We organized 11 discussion groups and 2 triangular groups with health-care users; 30 semi-structured interviews with key community informants; and 14 discussion groups with primary health care workers. A thematic content analysis was carried out. Health-care users and key community informants agree that health is a complex, broad, multifactorial concept that encompasses several interrelated dimensions (physical, psychological-emotional, social, occupational, intellectual, spiritual and environmental). The three participants' profiles consider health promotion indispensable despite defining it as complex and vague. In fact, most health-care users admit to having implemented some change to promote their health. The most powerful motivators to change lifestyles are having a disease, fear of becoming ill and taking care of oneself to maintain health. Health-care users believe that the main difficulties are associated with the physical, social, working and family environment, as well as lack of determination and motivation. They also highlight the need for more information. In relation to the assets and deficits of the neighbourhood, each group identifies those closer to their role. Generally, participants showed a holistic and positive concept of health and a more traditional, individual approach to health promotion. We consider therefore crucial to depart from the model of health services that focuses on the individual and the disease toward a socio-ecological health model that substantially increases the participation of health-care users and emphasizes health promotion, wellbeing and community participation.

Tanning bed use is classified as carcinogenic and is associated with an increased risk of skin cancer. The aim of this cross-sectional survey was to identify the most commonly stated reasons for tanning bed use among a sample of male and female community college students in eastern North Carolina. A brief, self-administered survey was distributed to students during English, Art, or Psychology class periods in 5 eastern North Carolina community colleges during the 2010 fall semester. The 95% response rate consisted of 487 returned surveys. Of the 487 respondents, 12.7% (N = 62) were current users, 24.5% (N = 119) were past users, and 62.2% (N = 303) reported never using tanning beds. Women (79%) were more likely than men (18%) to be current or former tanning bed users. Three African Americans reported current tanning bed use (4.8%). Reasons for tanning bed use were similar among men and women, with "I think I look better when I am tan" being the most commonly cited reason (70.2%) for tanning bed use. A convenience sample limits generalizability to all North Carolina students attending community college. Current tanning bed use was not widely reported. However, educational strategies for preventing tanning bed initiation or recurrence among male and female community college students should include appearance-driven factors.

Sleepio is a proven digital sleep improvement program based on cognitive behavioral therapy techniques. Users have the option to join an online community that includes weekly expert discussions, peer-to-peer discussion forums, and personal message walls. The aim of this study was to conduct an online survey to (1) explore the reasons for deciding to engage with the Sleepio online community, (2) explore the potential benefits arising from engagement with the online community, and (3) identify and describe any problematic issues related to use of the online community. We developed an online survey and posted an invitation to the community discussion forum inviting users to participate. In addition, we sent an email invitation to 970 individuals who had previously or were currently working through the Sleepio program to participate in this study. In total, 100 respondents (70/100, 70% female; mean age 51 years, range 26-82 years) completed the online survey. Most respondents had started Sleepio with chronic sleep problems (59/100, 59% up to 10 years; 35/100, 35% >10 years) and had actively engaged with the online community (85/100, 85%) had made a discussion or wall post). At the time of the survey, respondents had used Sleepio for a median of 12 weeks (range from 3 weeks to 2 years). We analyzed responses to the open-ended questions using thematic analysis. This analysis revealed 5 initial drivers for engagement: (1) the desire to connect with people facing similar issues, (2) seeking personalized advice, (3) curiosity, (4) being invited by other members, and (5) wanting to use all available sleep improvement tools. Advantages of engagement included access to continuous support, a reduced sense of isolation, being part of a nonjudgmental community, personalized advice, positive comparisons with others, encouragement to keep going, and altruism. We found 5 potential disadvantages: design and navigation issues, uncertain quality of user-generated content, negative comparisons with others, excessive time commitments, and data privacy concerns. Participants related their community experiences to engagement with the Sleepio program, with many stating it had supported their efforts to improve their sleep, as well as helping with adherence and commitment to the program. Despite some concerns, members regarded the Sleepio community as a valuable resource. Online communities may be a useful means through which to support long-term engagement with Web-based therapy for insomnia.

While overdose is a common cause of mortality among opioid injectors worldwide, little information exists on opioid overdoses or how context may influence overdose risk in Russia. This study sought to uncover social and structural aspects contributing to fatal overdose risk in St. Petersburg and assess prevention intervention feasibility. Twenty-one key informant interviews were conducted with drug users, treatment providers, toxicologists, police, and ambulance staff. Thematic coding of interview content was conducted to elucidate elements of the overdose risk environment. Several factors within St. Petersburg's environment were identified as shaping illicit drug users' risk behaviours and contributing to conditions of suboptimal response to overdose in the community. Most drug users live and experience overdoses at home, where family and home environment may mediate or moderate risk behaviours. The overdose risk environment is also worsened by inefficient emergency response infrastructure, insufficient cardiopulmonary or naloxone training resources, and the preponderance of abstinence-based treatment approaches to the exclusion of other treatment modalities. However, attitudes of drug users and law enforcement officials generally support overdose prevention intervention feasibility. Modifiable aspects of the risk environment suggest community-based and structural interventions, including overdose response training for drug users and professionals that encompasses naloxone distribution to the users and equipping more ambulances with naloxone. Local social and structural elements influence risk environments for overdose. Interventions at the community and structural levels to prevent and respond to opioid overdoses are needed for and integral to reducing overdose mortality in St. Petersburg.

Structural Factors Influencing Patterns of Drug Selling and Use and HIV Risk in the San Salvador Metropolitan Area

2013-01-01

This article explores differences in the social context in which crack sales and use and HIV risk take place in seven low-income communities in San Salvador, and structural factors that may influence these differences. The organization of drug selling varied among the communities on a number of dimensions including: whether drug sales were open or closed systems; the type of drug-selling site; and the participation of drug users in drug-distribution roles. Drug-use sites also varied according to whether crack was used in private, semiprivate, or public spaces, and whether individuals used drugs alone or with other drug users. Three patterns of drug use and selling were identified based on the dimensions outlined above. Structural factors that influenced these patterns included the geographic location of the communities, their physical layout, gang involvement in drug sales, and police surveillance. Implications for HIV risk and prevention are explored for each pattern. PMID:20550091

Abstract The agriGO platform, which has been serving the scientific community for >10 years, specifically focuses on gene ontology (GO) enrichment analyses of plant and agricultural species. We continuously maintain and update the databases and accommodate the various requests of our global users. Here, we present our updated agriGO that has a largely expanded number of supporting species (394) and datatypes (865). In addition, a larger number of species have been classified into groups covering crops, vegetables, fish, birds and insects closely related to the agricultural community. We further improved the computational efficiency, including the batch analysis and P-value distribution (PVD), and the user-friendliness of the web pages. More visualization features were added to the platform, including SEACOMPARE (cross comparison of singular enrichment analysis), direct acyclic graph (DAG) and Scatter Plots, which can be merged by choosing any significant GO term. The updated platform agriGO v2.0 is now publicly accessible at http://systemsbiology.cau.edu.cn/agriGOv2/. PMID:28472432

NASA's Earth Observing System Data and Information System (EOSDIS) has been a central component of NASA Earth observation program for over 10 years. It is one of the largest civilian science information system in the US, performing ingest, archive and distribution of over 3 terabytes of data per day much of which is from NASA s flagship missions Terra, Aqua and Aura. The system supports a variety of science disciplines including polar processes, land cover change, radiation budget, and most especially global climate change. The EOSDIS data centers, collocated with centers of science discipline expertise, archive and distribute standard data products produced by science investigator-led processing systems. Key to the success of EOSDIS is the concept of core versus community requirements. EOSDIS supports a core set of services to meet specific NASA needs and relies on community-developed services to meet specific user needs. EOSDIS offers a metadata registry, ECHO (Earth Observing System Clearinghouse), through which the scientific community can easily discover and exchange NASA s Earth science data and services. Users can search, manage, and access the contents of ECHO s registries (data and services) through user-developed and community-tailored interfaces or clients. The ECHO framework has become the primary access point for cross-Data Center search-and-order of EOSDIS and other Earth Science data holdings archived at the EOSDIS data centers. ECHO s Warehouse Inventory Search Tool (WIST) is the primary web-based client for discovering and ordering cross-discipline data from the EOSDIS data centers. The architecture of the EOSDIS provides a platform for the publication, discovery, understanding and access to NASA s Earth Observation resources and allows for easy integration of new datasets. The EOSDIS also has developed several methods for incorporating socioeconomic data into its data collection. Over the years, we have developed several methods for determining needs of the user community including use of the American Customer Satisfaction Index and a broad metrics program.

Background Since 2000, there has been a dramatic increase in methamphetamine use in South Africa, but little is known about the experiences of out-of-treatment users. This mixed-methods study describes the substance use histories, addiction symptoms, and treatment experiences of a community-recruited sample of methamphetamine users in Cape Town. Methods Using respondent driven sampling, 360 methamphetamine users (44% female) completed structured clinical interviews to assess substance abuse and treatment history and computerized surveys to assess drug-related risks. A sub-sample of 30 participants completed in-depth interviews to qualitatively explore experiences with methamphetamine use and drug treatment. Results Participants had used methamphetamine for an average of 7.06 years (SD=3.64). They reported using methamphetamine on an average of 23.49 of the past 30 days (SD=8.90); 60% used daily. The majority (90%) met ICD-10 criteria for dependence, and many reported severe social, financial, and legal consequences. While only 10% had ever received drug treatment, 90% reported that they wanted treatment. In the qualitative interviews, participants reported multiple barriers to treatment, including beliefs that treatment is ineffective and relapse is inevitable in their social context. They also identified important motivators, including desires to be drug free and improve family functioning. Conclusion This study yields valuable information to more effectively respond to emerging methamphetamine epidemics in South Africa and other low- and middle-income countries. Interventions to increase uptake of evidence-based services must actively seek out drug users and build motivation for treatment, and offer continuing care services to prevent relapse. Community education campaigns are also needed. PMID:25977205

2009-01-01

Background Natural History science is characterised by a single immense goal (to document, describe and synthesise all facets pertaining to the diversity of life) that can only be addressed through a seemingly infinite series of smaller studies. The discipline's failure to meaningfully connect these small studies with natural history's goal has made it hard to demonstrate the value of natural history to a wider scientific community. Digital technologies provide the means to bridge this gap. Results We describe the system architecture and template design of "Scratchpads", a data-publishing framework for groups of people to create their own social networks supporting natural history science. Scratchpads cater to the particular needs of individual research communities through a common database and system architecture. This is flexible and scalable enough to support multiple networks, each with its own choice of features, visual design, and constituent data. Our data model supports web services on standardised data elements that might be used by related initiatives such as GBIF and the Encyclopedia of Life. A Scratchpad allows users to organise data around user-defined or imported ontologies, including biological classifications. Automated semantic annotation and indexing is applied to all content, allowing users to navigate intuitively and curate diverse biological data, including content drawn from third party resources. A system of archiving citable pages allows stable referencing with unique identifiers and provides credit to contributors through normal citation processes. Conclusion Our framework currently serves more than 1,100 registered users across 100 sites, spanning academic, amateur and citizen-science audiences. These users have generated more than 130,000 nodes of content in the first two years of use. The template of our architecture may serve as a model to other research communities developing data publishing frameworks outside biodiversity research. PMID:19900302

2016-12-01

In order to facilitate and enhance better understanding of how to conserve life on earth and the environment that sustains it, Data Observation Network for Earth (DataONE) develops, implements, and shares educational activities and materials as part of its commitment to the education of its community, including scientific researchers, educators, and the public. Creating and maintaining educational materials that remain responsive to community needs is reliant on careful evaluations in order to enhance current and future resources. DataONE's extensive collaboration with individuals and organizations has informed the development of its educational resources and through these interactions, the need for a comprehensive, customizable education evaluation instrument became apparent. In this presentation, the authors will briefly describe the design requirements and research behind a prototype instrument that is intended to be used by the community for evaluation of its educational activities and resources. We will then demonstrate the functionality of a web based platform that enables users to identify the type of educational activity across multiple axes. This results in a set of structured evaluation questions that can be included in a survey instrument. Users can also access supporting documentation describing the types of question included in the output or simply download a full editable instrument. Our aim is that by providing the community with access to a structured evaluation instrument, Earth/Geoscience educators will be able to gather feedback easily and efficiently in order to help maintain the quality, currency/relevancy, and value of their resources, and ultimately, support a more data literate community.

2016-04-01

The use of open data in research faces challenges not restricted to inherent properties such as data quality, resolution of open data sets. Often Open data is catalogued insufficiently or fragmented. Software tools that support the effective discovery including the assessment of the data's appropriateness for research have shortcomings such as the lack of essential functionalities like support for data provenance. We believe that one of the reasons is the neglect of real end users requirements in the development process of aforementioned software tools. In the context of the FP7 Switch-On project we have pro-actively engaged the relevant user user community to collaboratively develop a means to publish, find and bind open data relevant for hydrologic research. Implementing key concepts of data discovery and exploration we have used state of the art web technologies to provide an interactive software tool that is easy to use yet powerful enough to satisfy the data discovery and access requirements of the hydrological research community.

2016-12-09

To explore perspectives and reported experiences of service users, community providers and policymakers related to volunteer health-worker services provision in a rural area of Myanmar. A qualitative interview study was conducted in rural communities with 54 service users and 17 community providers in Ayeyarwady Region, Myanmar, and with 14 national managers and policymakers in Yangon Myanmar. Topics included reasons for seeking health services, views and experiences, and comparison with experiences of other services. Data were analysed thematically using deductive and inductive coding. Accessibility and affordability were important to all participants. Service users described the particular relevance of trust, familiarity and acceptability in choosing a provider. Perceived quality and effectiveness were necessary for trust to develop. Perceived value of volunteers was a cross-cutting dimension, which was interpreted differently by different participants. Results suggest that volunteers are appropriate and valued, and support 'availability', 'accessibility' and 'acceptability' as dimensions of health services access in this setting. However, social complexities should be considered to ensure effective service delivery. Further research into trust-building, developing quality perceptions and resulting service-user choices would be useful to inform effective policy and planning.

To explore factors affecting tobacco users' perceived appropriateness of a brief and proactive tobacco cessation counseling program, ask, advise, and refer (AAR), at community pharmacies. Inductive thematic analysis. Southern Wisconsin during fall 2008. 24 tobacco users who had recently received brief and proactive tobacco cessation counseling at a community pharmacy. Semistructured telephone interviews conducted by primary author. Perceptions of a brief and proactive tobacco cessation counseling program conducted at community pharmacies. In conducting the thematic analysis, eight distinct themes were identified. Display of information and resources at pharmacies for use by tobacco users as needed was identified as the most predominant theme and was found to be most helpful by many respondents. Other themes identified in decreasing order of prevalence were: tobacco users' perceptions of the role of pharmacists in health care, tobacco users' belief that smoking could interact with a current medication or health condition, tobacco users' sensitivity toward their tobacco use behavior or being told what to do, nonconfrontational and friendly approach of pharmacists, tobacco users' readiness to quit at the time of AAR counseling, tobacco user initiation of tobacco use discussion, and tobacco users' belief that tobacco use is bad. Overall, this qualitative investigation suggests that several factors might influence tobacco users' perceived appropriateness of AAR counseling at community pharmacies. AAR might be well received by tobacco users and pharmacy patrons as long as it is done in a professional and respectful manner.

2007-12-01

The new GPIPS website portal provides community users with an intuitive and powerful interface to query the data products of the Galactic Plane Infrared Polarization Survey. The website, which was built using PHP for the front end and MySQL for the database back end, allows users to issue queries based on galactic or equatorial coordinates, GPIPS-specific identifiers, polarization information, magnitude information, and several other attributes. The returns are presented in HTML tables, with the added option of either downloading or being emailed an ASCII file including the same or more information from the database. Other functionalities of the website include providing details of the status of the Survey (which fields have been observed or are planned to be observed), techniques involved in data collection and analysis, and descriptions of the database contents and names. For this initial launch of the website, users may access the GPIPS polarization point source catalog and the deep coadd photometric point source catalog. Future planned developments include a graphics-based method for querying the database, as well as tools to combine neighboring GPIPS images into larger image files for both polarimetry and photometry. This work is partially supported by NSF grant AST-0607500.

Land Cover Change Community-based Processing and Analysis System (LC-ComPS): Lessons Learned from Technology Infusion

NASA Astrophysics Data System (ADS)

Masek, J.; Rao, A.; Gao, F.; Davis, P.; Jackson, G.; Huang, C.; Weinstein, B.

2008-12-01

The Land Cover Change Community-based Processing and Analysis System (LC-ComPS) combines grid technology, existing science modules, and dynamic workflows to enable users to complete advanced land data processing on data available from local and distributed archives. Changes in land cover represent a direct link between human activities and the global environment, and in turn affect Earth's climate. Thus characterizing land cover change has become a major goal for Earth observation science. Many science algorithms exist to generate new products (e.g., surface reflectance, change detection) used to study land cover change. The overall objective of the LC-ComPS is to release a set of tools and services to the land science community that can be implemented as a flexible LC-ComPS to produce surface reflectance and land-cover change information with ground resolution on the order of Landsat-class instruments. This package includes software modules for pre-processing Landsat-type satellite imagery (calibration, atmospheric correction, orthorectification, precision registration, BRDF correction) for performing land-cover change analysis and includes pre-built workflow chains to automatically generate surface reflectance and land-cover change products based on user input. In order to meet the project objectives, the team created the infrastructure (i.e., client-server system with graphical and machine interfaces) to expand the use of these existing science algorithm capabilities in a community with distributed, large data archives and processing centers. Because of the distributed nature of the user community, grid technology was chosen to unite the dispersed community resources. At that time, grid computing was not used consistently and operationally within the Earth science research community. Therefore, there was a learning curve to configure and implement the underlying public key infrastructure (PKI) interfaces, required for the user authentication, secure file transfer and remote job execution on the grid network of machines. In addition, science support was needed to vet that the grid technology did not have any adverse affects of the science module outputs. Other open source, unproven technologies, such as a workflow package to manage jobs submitted by the user, were infused into the overall system with successful results. This presentation will discuss the basic capabilities of LC-ComPS, explain how the technology was infused, and provide lessons learned for using and integrating the various technologies while developing and operating the system, and finally outline plans moving forward (maintenance and operations decisions) based on the experience to date.

2017-05-01

Although research has explored the ways in which people form virtual communities to converse about media figures, television shows, and similar topics, little research has examined the link between virtual communities and the parasocial relationships (PSRs) that are often the focus of these conversations and users' experiences in those virtual communities. We examined sense of community (SOC) on Twitter and Instagram as a function of users' motives for use and users' PSR on the sites. In addition to examining the relative importance of different motives for using Twitter and Instagram, we predicted that PSR would mediate the association between motives for use and SOC. Results of an online survey revealed that Instagram users (n = 276) reported stronger social interaction motives than did Twitter users (n = 223). Social interaction and expressive information sharing motives were directly positively associated with SOC for users of both sites. Instagram users also exhibited indirect effects of expressive information sharing and companionship motives on SOC, through PSR. These findings suggest potentially influential differences between Twitter and Instagram, particularly regarding the role of PSR in fostering a general SOC.

Crowdsourced Contributions to the Nation's Geodetic Elevation Infrastructure

NASA Astrophysics Data System (ADS)

Stone, W. A.

2014-12-01

NOAA's National Geodetic Survey (NGS), a United States Department of Commerce agency, is engaged in providing the nation's fundamental positioning infrastructure - the National Spatial Reference System (NSRS) - which includes the framework for latitude, longitude, and elevation determination as well as various geodetic models, tools, and data. Capitalizing on Global Navigation Satellite System (GNSS) technology for improved access to the nation's precise geodetic elevation infrastructure requires use of a geoid model, which relates GNSS-derived heights (ellipsoid heights) with traditional elevations (orthometric heights). NGS is facilitating the use of crowdsourced GNSS observations collected at published elevation control stations by the professional surveying, geospatial, and scientific communities to help improve NGS' geoid modeling capability. This collocation of published elevation data and newly collected GNSS data integrates together the two height systems. This effort in turn supports enhanced access to accurate elevation information across the nation, thereby benefiting all users of geospatial data. By partnering with the public in this collaborative effort, NGS is not only helping facilitate improvements to the elevation infrastructure for all users but also empowering users of NSRS with the capability to do their own high-accuracy positioning. The educational outreach facet of this effort helps inform the public, including the scientific community, about the utility of various NGS tools, including the widely used Online Positioning User Service (OPUS). OPUS plays a key role in providing user-friendly and high accuracy access to NSRS, with optional sharing of results with NGS and the public. All who are interested in helping evolve and improve the nationwide elevation determination capability are invited to participate in this nationwide partnership and to learn more about the geodetic infrastructure which is a vital component of viable spatial data for many disciplines, including the geosciences.

The Utqiaġvik (Barrow) area of northern Alaska is one of the most intensely researched locations in the Arctic and the Barrow Area Information Database (BAID, www.barrowmapped.org) tracks and facilitates a gamut of research, management, and educational activities in the area. BAID is a cyberinfrastructure (CI) that details much of the historic and extant research undertaken within in the Barrow region in a suite of interactive web-based mapping and information portals (geobrowsers). The BAID user community and target audience for BAID is diverse and includes research scientists, science logisticians, land managers, educators, students, and the general public. BAID contains information on more than 18,000 Barrow area research sites that extend back to the 1940's and more than 640 remote sensing images and geospatial datasets. In a web-based setting, users can zoom, pan, query, measure distance, save or print maps and query results, and filter or view information by space, time, and/or other tags. Recent advances include provision of differential global positioning (dGPS) system and high resolution aerial imagery support to visiting scientists, analysis and multitemporal mapping of over 120 km of coastline for erosion monitoring; maintenance of a wireless micrometeorological sensor network; links to Barrow area datasets housed at national data archives; a NOAA funded community outreach program for citizen science and public outreach on costal erosion; and substantial upgrades to the BAID website. Web mapping applications that have launched to the public include: an Imagery Time Viewer that allows users to compare imagery of the Barrow area between 1948 and the present; a Coastal Erosion Viewer that allows users to view long-term (1955-2015) and recent (2013-2015) rates of erosion for the Barrow area; and a Community Planning tool that allows users to view and print dynamic reports based on an array of basemaps including a new 0.5m resolution wetlands map designed to enhance decision making for development and land management.

2015-01-01

Background Understanding how people participate in and contribute to online health communities (OHCs) is useful knowledge in multiple domains. It is helpful for community managers in developing strategies for building community, for organizations in disseminating information about health interventions, and for researchers in understanding the social dynamics of peer support. Objective We sought to determine if any patterns were apparent in the nature of user participation across online health communities. Methods The current study involved a systematic review of all studies that have investigated the nature of participation in an online health community and have provided a quantifiable method for categorizing a person based on their participation style. A systematic search yielded 20 papers. Results Participatory styles were classified as either multidimensional (based on multiple metrics) or unidimensional (based on one metric). With respect to the multidimensional category, a total of 41 different participation styles were identified ranging from Influential Users who were leaders on the board to Topic-Focused Responders who focused on a specific topic and tended to respond to rather than initiate posts. However, there was little overlap in participation styles identified both across OHCs for different health conditions and within OHCs for specific health conditions. Five of the 41 styles emerged in more than one study (Hubs, Authorities, Facilitators, Prime Givers, and Discussants), but the remainder were reported in only one study. The focus of the unidimensional studies was on level of engagement and particularly on high-engaged users. Eight different metrics were used to evaluate level of engagement with the greatest focus on frequency of posts. Conclusions With the exception of high-engaged users based on high post frequency, the current review found little evidence for consistent participatory styles across different health communities. However, this area of research is in its infancy, with most of the studies included in the review being published in the last 2 years. Nevertheless, the review delivers a nomenclature for OHC participation styles and metrics and discusses important methodological issues that will provide a basis for future comparative research in the area. Further studies are required to systematically investigate a range of participatory styles, to investigate their association with different types of online health communities and to determine the contribution of different participatory styles within and across online health communities.

The Road to Independently Understandable Information

NASA Astrophysics Data System (ADS)

Habermann, T.; Robinson, E.

2017-12-01

The turn of the 21st century was a pivotal time in the Earth and Space Science information ecosystem. The Content Standard for Digital Geospatial Metadata (CSDGM) had existed for nearly a decade and ambitious new standards were just emerging. The U.S. Federal Geospatial Data Committee (FGDC) had extended many of the concepts from CSDGM into the International community with ISO 19115:2003 and the Consultative Committee for Space Data Systems (CCSDS) had migrated their Open Archival Information System (OAIS) Reference Model into an international standard (ISO 14721:2003). The OAIS model outlined the roles and responsibilities of archives with the principle role being preserving information and making it available to users, a "designated community", as a service to the data producer. It was mandatory for the archive to ensure that information is "independently understandable" to the designated community and to maintain that understanding through on-going partnerships between archives and designated communities. Standards can play a role in supporting these partnerships as designated communities expand across disciplinary and geographic boundaries. The ISO metadata standards include many capabilities that might make critical contributions to this goal. These include connections to resources outside of the metadata record (i.e. documentation) and mechanisms for ongoing incorporation of user feedback into the metadata stream. We will demonstrate these capabilities with examples of how they can increase understanding.

We study properties of five different social systems: (i) internet society of friends consisting of over 106 people, (ii) social network consisting of 3 × 104 individuals, who interact in a large virtual world of Massive Multiplayer Online Role Playing Games (MMORPGs), (iii) over 106 users of music community website, (iv) over 5 × 106 users of gamers community server and (v) over 0.25 × 106 users of books admirer website. Individuals included in large social network form an Internet community and organize themselves in groups of different sizes. The destiny of those systems, as well as the method of creating of new connections, are different, however we found that the properties of these networks are very similar. We have found that the network components size distribution follow the power-law scaling form. In all five systems we have found interesting scaling laws concerning human dynamics. Our research has shown how long people are interested in a single task, how much time they devote to it and how fast they are making friends. It is surprising that the time evolution of an individual connectivity is very similar in each system.

Web-based magazine design for self publishers

NASA Astrophysics Data System (ADS)

Hunter, Andrew; Slatter, David; Greig, Darryl

2011-03-01

Short run printing technology and web services such as MagCloud provide new opportunities for long-tail magazine publishing. They enable self publishers to supply magazines to a wide range of communities, including groups that are too small to be viable as target communities for conventional publishers. In a Web 2.0 world where users constantly discover new services and where they may be infrequent patrons of any single service, it is unreasonable to expect users to learn the complex service behaviors. Furthermore, we want to open up publishing opportunities to novices who are unlikely to have prior experience of publishing and who lack design expertise. Magazine design automation is an ambitious goal, but recent progress with another web service, Autophotobook, proves that some level of automation of publication design is feasible. This paper describes our current research effort to extend the automation capabilities of Autophotobook to address the issues of magazine design so that we can provide a service to support professional-quality self publishing by novice users for a wide range of community types and sizes.

Established in 1998, the Science Archive Facility (SAF) stores both the raw data generated by all ESO instruments and selected processed (science-ready) data. The growth of the SAF user community is analysed through access and publication statistics. Statistics are presented for archival users, who do not contribute to observing proposals, and contrasted with regular and archival users, who are successful in competing for observing time. Archival data from the SAF contribute to about one paper out of four that use data from ESO facilities. This study reveals that the blend of users constitutes a mixture of the traditional ESO community making novel use of the data and of a new community being built around the SAF.

This study examined the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Study participants were 75 Education and Public Outreach community members of NASA's Science Mission Directorate Earth Forum. In this mixed methods study, online workspace metrics were used to track participation and a survey completed by 21 members was used to quantify participation. For a more detailed analysis, 15 community members (5 highly active users, 5 average users, and 5 infrequent users) selected based on survey responses, were interviewed. Finally, survey data was gathered from 7 online facilitators to understand their role in the community. Data collected from these 21 community members and 5 facilitating members suggest that highly active users (logging into the workspace daily), were more likely to have transformative experiences, co-create knowledge, feel ownership of community knowledge, have extended opportunities for community exchange, and find new forms of evaluation. Average users shared some similar characteristics with both the highly active members and infrequent users, representing a group in transition as they become more engaged and active in the online workspace. Inactive users viewed the workspace as having little value, being difficult to navigate, being mainly for gaining basic information about events and community news, and as another demand on their time. Results show the online workspace component of the Earth Science Education and Outreach Forum is playing an important and emerging role for this community by supporting knowledge building and knowledge sharing, and growing in value for those that utilizing it more frequently. The evidence suggests that with increased participation or "usage" comes increased value to the participant and the organization. This research illustrates the possible change in mindset held by participating community members when it comes to the nature of co-location. Additionally, it may be of particular importance in exploring changes in the community members' feelings of connection and belonging.

The Information Quality Cluster (IQC) within the Federation of Earth Science Information Partners (ESIP) was initially formed in 2011 and has evolved significantly over time. The current objectives of the IQC are to: 1. Actively evaluate community data quality best practices and standards; 2. Improve capture, description, discovery, and usability of information about data quality in Earth science data products; 3. Ensure producers of data products are aware of standards and best practices for conveying data quality, and data providers distributors intermediaries establish, improve and evolve mechanisms to assist users in discovering and understanding data quality information; and 4. Consistently provide guidance to data managers and stewards on how best to implement data quality standards and best practices to ensure and improve maturity of their data products. The activities of the IQC include: 1. Identification of additional needs for consistently capturing, describing, and conveying quality information through use case studies with broad and diverse applications; 2. Establishing and providing community-wide guidance on roles and responsibilities of key players and stakeholders including users and management; 3. Prototyping of conveying quality information to users in a more consistent, transparent, and digestible manner; 4. Establishing a baseline of standards and best practices for data quality; 5. Evaluating recommendations from NASA's DQWG in a broader context and proposing possible implementations; and 6. Engaging data providers, data managers, and data user communities as resources to improve our standards and best practices. Following the principles of openness of the ESIP Federation, IQC invites all individuals interested in improving capture, description, discovery, and usability of information about data quality in Earth science data products to participate in its activities.

To evaluate the effectiveness of a needle social marketing strategy to reduce needle sharing and hepatitis C Virus (HCV)/HIV transmission among injecting drug users (IDU) in China. Two-armed, prospective, community-randomized prevention trial. Four counties/townships in Guangxi and Guangdong provinces; one randomized to intervention the other to control in each province. Injecting drug users: 823 (443 intervention, 382 control) at baseline and 852 (415 intervention, 407 control) at the second cross-sectional survey 12 months later. A needle social marketing programme, including promotion of safe injection norms and increased access to clean needles over a 12 month period. Cross sectional surveys at baseline and follow-up compared changes in drug using behaviours and HIV and HCV rates in the intervention and control communities. Needle sharing behaviours were similar in the two groups at baseline (68.4 vs. 67.8%), and dropped significantly to 35.3% in the intervention community and remained relatively stable in the control community (62.3%; P < 0.001). In a subset of cohort of new injectors, the incidence of HCV was significant lower in intervention than in control in both provinces (P < 0.001, P = 0.014) and overall (P < 0.001) but HIV was only significantly lower in intervention in Guangdong (P = 0.011). Needle social marketing can reduce risky injecting behaviour and HIV/HCV transmission among injecting drug users in China and should be expanded.

This study investigated the utilization of social media by the hearing aid (HA) community. The purpose of this survey was to analyze the participation of HA community in the social media websites. A systematic survey of online HA-related social media sources was conducted. Such sources were identified using appropriate search terms. Social media participation was quantified on the basis of posts and "likes." Five hundred fifty-seven social media sources were identified, including 174 Twitter accounts, 172 YouTube videos, 91 Facebook pages, 20 Facebook groups, 71 blogs, and 29 forums. Twitter and YouTube platforms showed the highest level of activity among social media users. The HA-related community used social media sources for advice and support, information sharing, and service-related information. HA users, other individuals, and organizations interested in HAs leave their digital footprint on a wide variety of social media sources. The community connects, offers support, and shares information on a variety of HA-related issues. The HA community is as active in social media utilization as other groups, such as the cochlear implant community, even though the patterns of their social media use are different because of their unique needs.

Multilabel user classification using the community structure of online networks.

We study the problem of semi-supervised, multi-label user classification of networked data in the online social platform setting. We propose a framework that combines unsupervised community extraction and supervised, community-based feature weighting before training a classifier. We introduce Approximate Regularized Commute-Time Embedding (ARCTE), an algorithm that projects the users of a social graph onto a latent space, but instead of packing the global structure into a matrix of predefined rank, as many spectral and neural representation learning methods do, it extracts local communities for all users in the graph in order to learn a sparse embedding. To this end, we employ an improvement of personalized PageRank algorithms for searching locally in each user's graph structure. Then, we perform supervised community feature weighting in order to boost the importance of highly predictive communities. We assess our method performance on the problem of user classification by performing an extensive comparative study among various recent methods based on graph embeddings. The comparison shows that ARCTE significantly outperforms the competition in almost all cases, achieving up to 35% relative improvement compared to the second best competing method in terms of F1-score.

As part of Robert Wood Johnson Foundation's Healthy Kids, Healthy Communities (HKHC) national grant program, a technical assistance team designed the HKHC Community Dashboard, an online progress documentation and networking system. The Dashboard was central to HKHC's multimethod program evaluation and became a communication interface for grantees and technical assistance providers. The Dashboard was designed through an iterative process of identifying needs and priorities; designing the user experience, technical development, and usability testing; and applying visual design. The system was created with an open-source content management system and support for building an online community of users. The site developer trained technical assistance providers at the national program office and evaluators, who subsequently trained all 49 grantees. Evaluators provided support for Dashboard users and populated the site with the bulk of its uploaded tools and resource documents. The system tracked progress through an interactive work plan template, regular documentation by local staff and partners, and data coding and analysis by the evaluation team. Other features included the ability to broadcast information to Dashboard users via e-mail, event calendars, discussion forums, private messaging, a resource clearinghouse, a technical assistance diary, and real-time progress reports. The average number of Dashboard posts was 694 per grantee during the grant period. Technical assistance providers and grantees uploaded a total of 1304 resource documents. The Dashboard functions with the highest grantee satisfaction were its interfaces for sharing and progress documentation. A majority of Dashboard users (69%) indicated a preference for continued access to the Dashboard's uploaded resource documents. The Dashboard was a useful and innovative tool for participatory evaluation of a large national grant program. While progress documentation added some burden to local project staff, the system proved to be a useful resource-sharing technology.

There is a debate about the effects of pro-anorexia (colloquially referred to as pro-ana) websites. Research suggests that the effect of these websites is not straightforward. Indeed, the actual function of these sites is disputed, with studies indicating both negative and positive effects. This is the first study which systematically examined the differences between pro-anorexia web communities in four main aspects: web language used (posts); web interests/search behaviors (queries); users' self-reported weight status and weight goals; and associated self-reported mood/pathology. We collected three primary sources of data, including messages posed on three pro-ana websites, a survey completed by over 1000 participants of a pro-ana website, and the searches made on the Bing search engine of pro-anorexia users. These data were analyzed for content, reported demographics and pathology, and behavior over time. Although members of the main pro-ana website investigated appear to be depressed, with high rates of self-harm and suicide attempts, users are significantly more interested in treatment, have wishes of procreation and reported the highest goal weights among the investigated sites. In contrast, users of other pro-ana websites investigated, are more interested in morbid themes including depression, self-harm and suicide. The percentage of severely malnourished website users, in general, appears to be small (20%). Our results indicate that a new strategy is required to facilitate the communication between mental health specialists and pro-ana web users, recognizing the differences in harm associated with different websites.

Gaining trust from the scientific climate change community and increasing the visibility of their data

NASA Astrophysics Data System (ADS)

Pfeil, B.; Diepenbroek, M.

2017-12-01

Climate science has a major impact not just within the field, but also has immediate significant societal and economic implications. Scientists are well aware that their research results may be discussed by policy-makers and the media, sometimes with hostile intent from climate science deniers. Sustainable and scrutinized data management is the backbone for future scientific research and vital to maintain the integrity and reputation of the climate science community. In 2009 a lack of openness regarding data acquisition data treatment was one of the main factors in Climategate that severely damaged the community's image - and efficient data sharing and management can prevent this in the future. Data repositories can only operate effectively if they have the trust of their users: this includes both the data providers and data users. Both groups have to be assured that data treatment and quality control follows internationally agreed SOPs (standard operating procedures), is transparent, documented and traceable. Users want easy access to data and have to be assured that data is citable, allows reproducibility and can be used with confidence, which requires that both the data and accompanying metadata are of the highest possible quality. Building up trust from both communities takes time and requires collaboration, getting feedback from the community and addressing their needs. This presentation will show the basic needs and challenges for data repositories, and will illustrate how the marine carbon climate change community has successfully addressed these through the SOCAT (Surface Ocean CO2 Atlas) project. The project actively involves both data providers and users throughout the design and implementation of their infrastructures. Scientists are directly involved in quality control of the data and metadata, increasing trust in the data and encouraging international collaboration, which in turn increases the visibility of both the community and its data.

This study explores baby boomer-aged adults' experiences accessing an emotional health program (EHP) in a community-based seniors' center, examining differences between it and an older cohort of users. Data generation includes client-based surveys (n=118), in-depth qualitative interviews (n=20) with client users and professionally-trained counselors (n=2), and a focus group with peer support service worker (n=14). Key findings suggest EHPs as a preventative strategy to address familial abuse, the need for education and support on sexual health and dating, and the need to combat ageism to improve access. Community-based seniors' centers as a cost-effective approach to health promotion is also highlighted.

Air Quality uFIND: User-oriented Tool Set for Air Quality Data Discovery and Access

Historically, there have been major impediments to seamless and effective data usage encountered by both data providers and users. Over the last five years, the international Air Quality (AQ) Community has worked through forums such as the Group on Earth Observations AQ Community of Practice, the ESIP AQ Working Group, and the Task Force on Hemispheric Transport of Air Pollution to converge on data format standards (e.g., netCDF), data access standards (e.g., Open Geospatial Consortium Web Coverage Services), metadata standards (e.g., ISO 19115), as well as other conventions (e.g., CF Naming Convention) in order to build an Air Quality Data Network. The centerpiece of the AQ Data Network is the web service-based tool set: user-oriented Filtering and Identification of Networked Data. The purpose of uFIND is to provide rich and powerful facilities for the user to: a) discover and choose a desired dataset by navigation through the multi-dimensional metadata space using faceted search, b) seamlessly access and browse datasets, and c) use uFINDs facilities as a web service for mashups with other AQ applications and portals. In a user-centric information system such as uFIND, the user experience is improved by metadata that includes the general fields for discovery as well as community-specific metadata to narrow the search beyond space, time and generic keyword searches. However, even with the community-specific additions, the ISO 19115 records were formed in compliance with the standard, so that other standards-based search interface could leverage this additional information. To identify the fields necessary for metadata discovery we started with the ISO 19115 Core Metadata fields and fields that were needed for a Catalog Service for the Web (CSW) Record. This fulfilled two goals - one to create valid ISO 19115 records and the other to be able to retrieve the records through a Catalog Service for the Web query. Beyond the required set of fields, the AQ Community added additional fields using a combination of keywords and ISO 19115 fields. These extensions allow discovery by measurement platform or observed phenomena. Beyond discovery metadata, the AQ records include service identification objects that allow standards-based clients, such as some brokers, to access the data found via OGC WCS or WMS data access protocols. uFIND, is one such smart client, this combination of discovery and access metadata allows the user to preview each registered dataset through spatial and temporal views; observe the data access and usage pattern and also find links to dataset-specific metadata directly in uFIND. The AQ data providers also benefit from this architecture since their data products are easier to find and re-use, enhancing the relevance and importance of their products. Finally, the earth science community at large benefits from the Service Oriented Architecture of uFIND, since it is a service itself and allows service-based interfacing with providers and users of the metadata, allowing uFIND facets to be further refined for a particular AQ application or completely repurposed for other Earth Science domains that use the same set of data access and metadata standards.

2012-02-01

The study aimed to evaluate the impact of introducing designated care coordinators into an acute mental health inpatient unit in terms of service delivery, clinical outcomes, and service user and significant other perceptions. A pre-post-controlled design was implemented with a consecutive sample of 292 service users admitted and staying more than 5 days in two wards, with care coordinators introduced in one ward. Data were obtained from clinical records, standard measures, and service user and significant other surveys. Care coordinator input was associated with significant improvements in service delivery and stronger involvement of significant others and community resources. Care-coordinated clients showed significantly better clinical outcomes, including the Health of Nations Outcome Scales behaviour subscale, less time in the intensive care subunit, less community crisis team input in the week following discharge, and lower rates of readmission in the month following discharge. Care-coordinated service users and their significant others gave higher ratings of service delivery, outcome, and satisfaction. The results indicate that designated care coordinators significantly improve care processes, outcomes, and service user experience in acute inpatient mental health settings. © 2011 The Authors.

Librett, John J; Yore, Michelle M; Schmid, Thomas L

2006-11-01

The Task Force on Community Preventive Services strongly recommends environmental interventions that include enhanced access to opportunities for physical activity, such as walking and cycling trails. Although accumulating evidence indicates that trails can be effective in increasing physical activity, little is known about trail users. Cross-sectional analysis of a national sample of 3717 adults from the HealthStyles and ConsumerStyles surveys using logistic regression to determine physical activity patterns and sociodemographic correlates related to trail use, and to identify support regarding trail development policies. Almost 13% (12.7%) of the sample reported using trails at least once a month and 24.3% at least once a week. People who reported using trails at least once a week were twice as likely than people who reported rarely or never using trails to meet physical activity recommendations (odds ratio=2.3, 95% confidence interval=1.9-2.8). Nearly half (43.6%) of the non-trail users supported expanded public spaces for people to exercise, and 36.4% of the non-trail users reported that they would be willing to pay more taxes to build more parks and trails in their community. Community trails facilitate physical activity, and almost half of frequent trail users report that access to trails and other green space is important in choosing a place to live. These results support the need for prospective research on whether newly built trails promote physical activity in previously inactive people.

Although skilled birth care contributes significantly to the prevention of maternal and newborn morbidity and mortality, utilization of such care is poor in mid- and far-western Nepal. This study explored the perceptions of service users and providers regarding barriers to skilled birth care. We conducted 24 focus group discussions, 12 each with service users and service providers from different health institutions in mid- and far-western Nepal. All discussions examined the perceptions and experiences of service users and providers regarding barriers to skilled birth care and explored possible solutions to overcoming such barriers. Our results determined that major barriers to skilled birth care include inadequate knowledge of the importance of services offered by skilled birth attendants (SBAs), distance to health facilities, unavailability of transport services, and poor availability of SBAs. Other barriers included poor infrastructure, meager services, inadequate information about services/facilities, cultural practices and beliefs, and low prioritization of birth care. Moreover, the tradition of isolating women during and after childbirth decreased the likelihood that women would utilize delivery care services at health facilities. Service users and providers perceived inadequate availability and accessibility of skilled birth care in remote areas of Nepal, and overall utilization of these services was poor. Therefore, training and recruiting locally available health workers, helping community groups establish transport mechanisms, upgrading physical facilities and services at health institutions, and increasing community awareness of the importance of skilled birth care will help bridge these gaps.

2018-01-01

NASA's Earth Observing System Data and Information System (EOSDIS) has been a central component of the NASA Earth observation program since the 1990's. EOSDIS manages data covering a wide range of Earth science disciplines including cryosphere, land cover change, polar processes, field campaigns, ocean surface, digital elevation, atmosphere dynamics and composition, and inter-disciplinary research, and many others. One of the key components of EOSDIS is a set of twelve discipline-based Distributed Active Archive Centers (DAACs) distributed across the United States. Managed by NASA's Earth Science Data and Information System (ESDIS) Project at Goddard Space Flight Center, these DAACs serve over 3 million users globally. The ESDIS Project provides the infrastructure support for EOSDIS, which includes other components such as the Science Investigator-led Processing systems (SIPS), common metadata and metrics management systems, specialized network systems, standards management, and centralized support for use of commercial cloud capabilities. Given the long-term requirements, and the rapid pace of information technology and changing expectations of the user community, EOSDIS has evolved continually over the past three decades. However, many challenges remain. Challenges addressed in this paper include: growing volume and variety, achieving consistency across a diverse set of data producers, managing information about a large number of datasets, migration to a cloud computing environment, optimizing data discovery and access, incorporating user feedback from a diverse community, keeping metadata updated as data collections grow and age, and ensuring that all the content needed for understanding datasets by future users is identified and preserved.

A review of case studies about usability in eight Free/Libre/Open Source Software (FLOSS) projects showed that an important issue regarding a usability initiative in the project was the lack of user research. User research is a key component in the user-centered design (UCD) process and a necessary step for creating usable products. Reasons why FLOSS projects suffered from a lack of user research included poor or unclear project leadership, cultural differences between developer and designers, and a lack of usability engineers. By identifying these critical issues, the FLOSS usability community can begin addressing problems in the efficacy of usability activities and work towards creating more usable FLOSS products.

As more Earth science software tools and services move to the web--the design and usability of those tools become ever more important. A good user interface is becoming expected and users are becoming increasingly intolerant of websites and web applications that work against them. The Earthdata UI Pattern Library attempts to give these scientists and developers the design tools they need to make usable, compelling user interfaces without the associated overhead of using a full design team. Patterns are tested and functional user interface elements targeted specifically at the Earth science community and will include web layouts, buttons, tables, typography, iconography, mapping and visualization/graphing widgets. These UI elements have emerged as the result of extensive user testing, research and software development within the NASA Earthdata team over the past year.

The Web 2.0 digital environment is revolutionizing how users communicate and relate to each other, and how information is shared, created, and recreated within user communities. The social media technologies in the Web 2.0 digital ecosystem are fundamentally changing the opportunities and dangers in disseminating qualitative health research. The social changes influenced by digital innovations shift dissemination from passive consumption to user-centered, apomediated cooperative approaches, the features of which are underutilized by many qualitative researchers. We identify opportunities new digital media presents for knowledge dissemination activities including access to wider audiences with few gatekeeper constraints, new perspectives, and symbiotic relationships between researchers and users. We also address some of the challenges in embracing these technologies including lack of control, potential for unethical co-optation of work, and cyberbullying. Finally, we offer solutions to enhance research dissemination in sustainable, ethical, and effective strategies. © The Author(s) 2015.

Developing community networks to deliver HIV prevention interventions.

Outreach has a long history in health and social service programs as an important method for reaching at-risk persons within their communities. One method of "outreach" is based on the recruitment of networks of community members (or "networkers") to deliver HIV prevention messages and materials in the context of their social networks and everyday lives. This paper documents the experiences of the AIDS Community Demonstration Projects in recruiting networkers to deliver HIV prevention interventions to high-risk populations, including injecting drug users not in treatment; female sex partners of injecting drug users; female sex traders; men who have sex with men but do not self-identify as gay; and youth in high-risk situations. The authors interviewed project staff and reviewed project records of the implementation of community networks in five cities. Across cities, the projects successfully recruited persons into one or more community networks to distribute small media materials, condoms, and bleach kits, and encourage risk-reduction behaviors among community members. Networkers' continuing participation was enlisted through a variety of monetary and nonmonetary incentives. While continuous recruitment of networkers was necessary due to attrition, most interventions reported maintaining a core group of networkers. In addition, the projects appeared to serve as a starting point for some networkers to become more active in other community events and issues. PMID:8862156

I will discuss challenges faced by IRSA in the next decade due to changes in our user base: the dissolution of wavelength boundaries among astronomers, and the education of astronomers as data scientists. While the fraction of astronomers who use infrared data has increased drastically in the era of Spitzer, Herschel, and WISE, most people who do science with those data sets don’t use infrared data exclusively or identify as “Infrared astronomers”. Our archive, and others, need to be responsive to the needs of an increasingly multiwavelength community, and those exploring time domain astronomy. That means making the archives interlink seamlessly, while preserving expert knowledge so that data don’t get misused. As astronomical data sets grow in volume, users will increasingly expect server side resources, including both storage and analysis resources. These expectations come with a host of ramifications, from cost to security. Our archives must be built to satisfy the needs of both the power user and the beginning astronomer. I will discuss how IRSA plans to meet the evolving needs of our user community.

User's manual for the National Water-Quality Assessment Program Invertebrate Data Analysis System (IDAS) software, version 5

Cuffney, Thomas F.; Brightbill, Robin A.

2011-01-01

The Invertebrate Data Analysis System (IDAS) software was developed to provide an accurate, consistent, and efficient mechanism for analyzing invertebrate data collected as part of the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program. The IDAS software is a stand-alone program for personal computers that run Microsoft Windows(Registered). It allows users to read data downloaded from the NAWQA Program Biological Transactional Database (Bio-TDB) or to import data from other sources either as Microsoft Excel(Registered) or Microsoft Access(Registered) files. The program consists of five modules: Edit Data, Data Preparation, Calculate Community Metrics, Calculate Diversities and Similarities, and Data Export. The Edit Data module allows the user to subset data on the basis of taxonomy or sample type, extract a random subsample of data, combine or delete data, summarize distributions, resolve ambiguous taxa (see glossary) and conditional/provisional taxa, import non-NAWQA data, and maintain and create files of invertebrate attributes that are used in the calculation of invertebrate metrics. The Data Preparation module allows the user to select the type(s) of sample(s) to process, calculate densities, delete taxa on the basis of laboratory processing notes, delete pupae or terrestrial adults, combine lifestages or keep them separate, select a lowest taxonomic level for analysis, delete rare taxa on the basis of the number of sites where a taxon occurs and (or) the abundance of a taxon in a sample, and resolve taxonomic ambiguities by one of four methods. The Calculate Community Metrics module allows the user to calculate 184 community metrics, including metrics based on organism tolerances, functional feeding groups, and behavior. The Calculate Diversities and Similarities module allows the user to calculate nine diversity and eight similarity indices. The Data Export module allows the user to export data to other software packages (CANOCO, Primer, PC-ORD, MVSP) and produce tables of community data that can be imported into spreadsheet, database, graphics, statistics, and word-processing programs. The IDAS program facilitates the documentation of analyses by keeping a log of the data that are processed, the files that are generated, and the program settings used to process the data. Though the IDAS program was developed to process NAWQA Program invertebrate data downloaded from Bio-TDB, the Edit Data module includes tools that can be used to convert non-NAWQA data into Bio-TDB format. Consequently, the data manipulation, analysis, and export procedures provided by the IDAS program can be used to process data generated outside of the NAWQA Program.

The Iowa Flood Information System (IFIS) is a web-based platform developed by the Iowa Flood Center (IFC) to provide access to flood inundation maps, real-time flood conditions, flood forecasts both short-term and seasonal, flood-related data, information and interactive visualizations for communities in Iowa. The key element of the system's architecture is the notion of community. Locations of the communities, those near streams and rivers, define basin boundaries. The IFIS provides community-centric watershed and river characteristics, weather (rainfall) conditions, and streamflow data and visualization tools. Interactive interfaces allow access to inundation maps for different stage and return period values, and flooding scenarios with contributions from multiple rivers. Real-time and historical data of water levels, gauge heights, and rainfall conditions are available in the IFIS by streaming data from automated IFC bridge sensors, USGS stream gauges, NEXRAD radars, and NWS forecasts. Simple 2D and 3D interactive visualizations in the IFIS make the data more understandable to general public. Users are able to filter data sources for their communities and selected rivers. The data and information on IFIS is also accessible through web services and mobile applications. The IFIS is optimized for various browsers and screen sizes to provide access through multiple platforms including tablets and mobile devices. The IFIS includes a rainfall-runoff forecast model to provide a five-day flood risk estimate for around 500 communities in Iowa. Multiple view modes in the IFIS accommodate different user types from general public to researchers and decision makers by providing different level of tools and details. River view mode allows users to visualize data from multiple IFC bridge sensors and USGS stream gauges to follow flooding condition along a river. The IFIS will help communities make better-informed decisions on the occurrence of floods, and will alert communities in advance to help minimize damage of floods. This presentation provides an overview and live demonstration of the tools and interfaces in the IFIS developed to date to provide a platform for one-stop access to flood related data, visualizations, flood conditions, and forecast.

Cognitive impairment is very common in late-life depression, principally affecting executive skills and information processing speed. The aim of the study was to examine the effect of antidepressant treatment on cognitive performances over a 10-year period. The community-based cohort included 7381 participants aged 65 years and above. Five cognitive domains (verbal fluency, psychomotor speed, executive function, visuospatial skills and global cognition) were assessed up to five times over 10 years of follow-up. Treatment groups included participants under a specific antidepressant class at both baseline and the first follow-up and their follow-up cognitive data were considered until the last consecutive follow-up with a report of antidepressant use of the same class. Linear mixed models were used to compare baseline cognitive performance and cognitive decline over time according to antidepressant treatment. The models were adjusted for multiple confounders including residual depressive symptoms assessed by the Center for Epidemiologic Studies-Depression scale. At baseline, 4.0% of participants were taking antidepressants. Compared to non-users, tricyclic antidepressant users had lower baseline performances in verbal fluency, visual memory and psychomotor speed, and selective serotonin reuptake inhibitor users in verbal fluency and psychomotor speed. For the two other cognitive abilities, executive function and global cognition, no significant differences were found at baseline irrespective of the antidepressant class. Regarding changes over time, no significant differences were observed in comparison with non-users whatever the cognitive domain, except for a slight additional improvement over the follow-up in verbal fluency skills for tricyclic antidepressant users. In this large elderly general population cohort, we found no evidence for an association between antidepressant use and post-treatment cognitive decline over 10 years of follow-up in various cognitive domains.

Interventions for tobacco cessation in the dental setting.

Tobacco use has significant adverse effects on oral health. Oral health professionals in the dental office or community setting have a unique opportunity to increase tobacco abstinence rates among tobacco users. This review assesses the effectiveness of interventions for tobacco cessation delivered by oral health professionals and offered to cigarette smokers and smokeless tobacco users in the dental office or community setting. We searched the Cochrane Tobacco Addiction Group Specialized Register (CENTRAL), MEDLINE (1966-November 2011), EMBASE (1988-November 2011), CINAHL (1982-November 2011), Healthstar (1975-November 2011), ERIC (1967-November 2011), PsycINFO (1984-November 2011), National Technical Information Service database (NTIS, 1964-November 2011), Dissertation Abstracts Online (1861-November 2011), Database of Abstract of Reviews of Effectiveness (DARE, 1995-November 2011), and Web of Science (1993-November 2011). We included randomized and pseudo-randomized clinical trials assessing tobacco cessation interventions conducted by oral health professionals in the dental office or community setting with at least six months of follow-up. Two authors independently reviewed abstracts for potential inclusion and abstracted data from included trials. Disagreements were resolved by consensus. The primary outcome was abstinence from smoking or all tobacco use (for users of smokeless tobacco) at the longest follow-up, using the strictest definition of abstinence reported. The effect was summarised as an odds ratio, with correction for clustering where appropriate. Heterogeneity was assessed using the I² statistic and where appropriate a pooled effect was estimated using an inverse variance fixed-effect model. Fourteen clinical trials met the criteria for inclusion in this review. Included studies assessed the efficacy of interventions in the dental office or in a community school or college setting. Six studies evaluated the effectiveness of interventions among smokeless tobacco (ST) users, and eight studies evaluated interventions among cigarette smokers, six of which involved adult smokers in dental practice settings. All studies employed behavioral interventions and only one required pharmacotherapy as an interventional component. All studies included an oral examination component. Pooling all 14 studies suggested that interventions conducted by oral health professionals can increase tobacco abstinence rates (odds ratio [OR] 1.71, 95% confidence interval [CI] 1.44 to 2.03) at six months or longer, but there was evidence of heterogeneity (I² = 61%). Within the subgroup of interventions for smokers, heterogeneity was smaller (I² = 51%), but was largely attributable to a large study showing no evidence of benefit. Within this subgroup there were five studies which involved adult smokers in dental practice settings. Pooling these showed clear evidence of benefit and minimal heterogeneity (OR 2.38, 95% CI 1.70 to 3.35, 5 studies, I² = 3%) but this was a posthoc subgroup analysis. Amongst the studies in smokeless tobacco users the heterogeneity was also attributable to a large study showing no sign of benefit, possibly due to intervention spillover to control colleges; the other five studies indicated that interventions for ST users were effective (OR 1.70; 95% CI 1.36 to 2.11). Available evidence suggests that behavioral interventions for tobacco cessation conducted by oral health professionals incorporating an oral examination component in the dental office or community setting may increase tobacco abstinence rates among both cigarette smokers and smokeless tobacco users. Differences between the studies limit the ability to make conclusive recommendations regarding the intervention components that should be incorporated into clinical practice, however, behavioral counselling (typically brief) in conjunction with an oral examination was a consistent intervention component that was also provided in some control groups.

An online health-promoting community (OHPC) has the potential to promote health and advance new means of dialogue between public health representatives and the general public. The aim of this study was to examine what aspects of an OHPC that are critical for satisfying the needs of the user community and public health goals and service capabilities. Community-based participatory research methods were used for data collection and analysis, and participatory design principles to develop a case study OHPC for adolescents. Qualitative data from adolescents on health appraisals and perspectives on health information were collected in a Swedish health service region and classified into categories of user health information exchange needs. A composite design rationale for the OHPC was completed by linking the identified user needs, user-derived requirements, and technical and organizational systems solutions. Conflicts between end-user requirements and organizational goals and resources were identified. The most prominent health information needs were associated to food, exercise, and well-being. The assessment of the design rationale document and prototype in light of the regional public health goals and service capabilities showed that compromises were needed to resolve conflicts involving the management of organizational resources and responsibilities. The users wanted to discuss health issues with health experts having little time to set aside to the OHPC and it was unclear who should set the norms for the online discussions. OHPCs can be designed to satisfy both the needs of user communities and public health goals and service capabilities. Compromises are needed to resolve conflicts between users' needs to discuss health issues with domain experts and the management of resources and responsibilities in public health organizations.

Communities of Practice Transition Online - Lessons learned from NASA's EPO Online Workspace

The Earth Forum Education and Public Outreach (EP/O) community has long interacted to better their practice as a community as well as individually. Working together to share knowledge and grow, they function as a community of practice. In 2009, NASA designed and implemented an online workspace in hopes of promoting the communities continued interactions. This study examines the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Study participants were 75 Education and Public Outreach community members of NASA's Science Mission Directorate Earth Forum. In this mixed methods study, online workspace metrics were used to track participation and a survey completed by 21 members was used to quantify participation. For a more detailed analysis, 15 community members (five highly active users, five average users, and five infrequent users) selected based on survey responses, were interviewed. Finally, survey data was gathered from seven online facilitators to understand their role in the community. Data collected from these 21 community members and five facilitating members suggest that highly active users (logging into the workspace daily), were more likely to have transformative experiences, co-create knowledge, feel ownership of community knowledge, have extended opportunities for community exchange, and find new forms of evaluation. Average users shared some similar characteristics with both the highly active members and infrequent users, representing a group in transition as they become more engaged and active in the online workspace. Inactive users viewed the workspace as having little value, being difficult to navigate, being mainly for gaining basic information about events and community news, and as another demand on their time. Results show the online workspace component of the Earth Science Education and Outreach Forum is playing an important and emerging role for this community by supporting knowledge building and knowledge sharing, and growing in value for those that utilizing it more frequently. The evidence suggests that with increased participation or "usage" comes increased value to the participant and the organization. This research illustrates the possible change in mindset held by participating community members when it comes to the nature of co-location. Additionally, it may be of particular importance in exploring changes in the community members' feelings of connection and belonging.

Online communities are becoming increasingly important as platforms for large-scale human cooperation. These communities allow users seeking and sharing professional skills to solve problems collaboratively. To investigate how users cooperate to complete a large number of knowledge-producing tasks, we analyze Stack Exchange, one of the largest question and answer systems in the world. We construct attention networks to model the growth of 110 communities in the Stack Exchange system and quantify individual answering strategies using the linking dynamics on attention networks. We identify two answering strategies. Strategy A aims at performing maintenance by doing simple tasks, whereas strategy B aims at investing time in doing challenging tasks. Both strategies are important: empirical evidence shows that strategy A decreases the median waiting time for answers and strategy B increases the acceptance rate of answers. In investigating the strategic persistence of users, we find that users tends to stick on the same strategy over time in a community, but switch from one strategy to the other across communities. This finding reveals the different sets of knowledge and skills between users. A balance between the population of users taking A and B strategies that approximates 2:1, is found to be optimal to the sustainable growth of communities. PMID:26934733

The FP7 project "Climate Information Portal for Copernicus" (CLIPC) is developing a demonstration portal for the Copernicus Climate Change Service (C3S). This project is one of a suite of FP7 research activities which are administratively independent of Copernicus, focussed on creating the technical and scientific building blocks needed for the service. It is to be expected that at EGU 2015 there will be many presentations describing portals delivering new and innovative ranges of services. It would be unwise to seek to replace all this creative activity with a single portal -- instead CLIPC is designing a portal to make distributed resources more accessible through flexible discovery systems. CLIPC needs to deliver more than a directory of resources: resources need to be presented in common protocols so that users can access multiple datasets. More information about the project objectives is available at www.clipc.eu. The gulf between the climate science communities and the end user communities is a central challenge being addressed in the project. It is important to understand that there is significant diversity and multiple communication barriers within these two sets of communities as well as between them. The CLIPC services must presentation will provide a review of progress towards this ambitious goal, through a discussion of user requirements activities, an overview of the proposed architecture, work on assessing and adjusting model biasses, and a discussion of the climate impact indicators which will be provided through the portal. When looking at the usability of data for the various users, CLIPC will implement a set of services functioning as a "knowledge base" supplying information to users about the data, including definitions of terminology used, quality of datasets, versioning, and user annotations.

Growing recognition of the importance of sharing scientific data more widely and openly has refocused attention on the state of data repositories, including both discipline- or topic-oriented data centers and institutional repositories. Data creators often have several alternatives for depositing and disseminating their natural, social, health, or engineering science data. In selecting a repository for their data, data creators and other stakeholders such as their funding agencies may wish to consider the user community or communities served, the type and quality of data products already offered, and the degree of data stewardship and associated services provided. Some data repositories serve general communities, e.g., those in their host institution or region, whereas others tailor their services to particular scientific disciplines or topical areas. Some repositories are selective when acquiring data and conduct extensive curation and reviews to ensure that data products meet quality standards. Many repositories have secured credentials and established a track record for providing trustworthy, high quality data and services. The NASA Socioeconomic Data and Applications Center (SEDAC) serves users interested in human-environment interactions, including researchers, students, and applied users from diverse sectors. SEDAC is selective when choosing data for dissemination, conducting several reviews of data products and services prior to release. SEDAC works with data producers to continually improve the quality of its open data products and services. As a Distributed Active Archive Center (DAAC) of the NASA Earth Observing System Data and Information System, SEDAC is committed to improving the accessibility, interoperability, and usability of its data in conjunction with data available from other DAACs, as well as other relevant data sources. SEDAC is certified as a Regular Member of the International Council for Science World Data System (ICSU-WDS).

In order to help provide access to advanced micro-electro-mechanical systems (MEMS) technologies and lower the barriers for both industry and academia, the Microelectronic Center of North Carolina (MCNC) and ARPA have developed a program which provides users with access to both MEMS processes and advanced electronic integration techniques. The four distinct aspects of this program, the multi-user MEMS processes (MUMP's), the consolidated micro-mechanical element library, smart MEMS, and the MEMS technology network are described in this paper. MUMP's is an ARPA-supported program created to provide inexpensive access to MEMS technology in a multi-user environment. It is both a proof-of-concept and educational tool that aids in the development of MEMS in the domestic community. MUMP's technologies currently include a 3-layer poly-silicon surface micromachining process and LIGA (lithography, electroforming, and injection molding) processes that provide reasonable design flexibility within set guidelines. The consolidated micromechanical element library (CaMEL) is a library of active and passive MEMS structures that can be downloaded by the MEMS community via the internet. Smart MEMS is the development of advanced electronics integration techniques for MEMS through the application of flip chip technology. The MEMS technology network (TechNet) is a menu of standard substrates and MEMS fabrication processes that can be purchased and combined to create unique process flows. TechNet provides the MEMS community greater flexibility and enhanced technology accessibility.

Really Simple Syndication (RSS) Feeds have become more standard means of sharing information, and a DataCasting tool was created as a NASA Technology Infusion effort to make RSS-based technology for accessing Earth Science information available. The United States Geological Survey (USGS) has also started using social media to allow the community access to news feeds and real-time earthquake alerts; listen to podcasts; get updates on new USGS publications, videos, and photographs; and more. Twitter feeds have been implemented in 2011 for the USGS Land Cover and Landsat user communities. In early 2011, the NASA Land Processes Distributed Active Archive Center (LP DAAC) user working group suggested the investigation of concepts for creating and distributing "bundles" of data, which would aggregate theme-based data sets from multiple sources. The LP DAAC is planning to explore the use of standard social bookmarking tools to support community developed bundles through the use of tools such as Delicious, Digg, or StumbleUpon. This concept would allow science users to organize and discover common links to data resources based on community developed tags, or a folksonomy. There are challenges that will need to be addressed such as maintaining the quality of tags but a social bookmarking system may have advantages over traditional search engines or formal ontologies for identifying and labeling various data sets relevant to a theme. As classification is done by the community of scientists who understand the data, the tagged data sets will result in a growing inventory of useful bundles.

HIV prevention researchers have increasingly advocated structural interventions that address factors in the social, political and economic context to reduce disparities of HIV/AIDS among disadvantaged populations. This paper draws on data collected in three different types of low-income communities (n=6) in the San Salvador metropolitan area in El Salvador. Nine focus group discussions were conducted between January 2006 - July 2007, six with community leaders, and three with crack cocaine users, as well as in-depth interviews with 20 crack users and crack dealers. We explore opportunities and barriers to the implementation of a community-level, structural intervention. We first analyze the different forms of leadership, and other community resources including existing HIV prevention activities that could potentially be used to address the related problems of crack use and HIV in the communities, and the structural factors that may act as barriers to capitalizing on communities’ strengths in interventions. Each of the communities studied demonstrated different resources that stem from each community's unique history and geographic location. HIV testing and prevention resources varied widely among the communities, with resources concentrated in one Older Central community despite a strong need in all communities. In many communities, fear of gang violence and non-responsiveness by government agencies to communities’ needs have discouraged community organizing. In the discussion, we offer concrete suggestions for developing and implementing structural interventions to reduce HIV risks that use communities’ different but complementary resources.

In many African countries, user fees have failed to achieve intended access and quality of care improvements. Subsequent user fee reduction or elimination policies have often been poorly planned, without alternative sources of income for facilities. We describe early implementation of an innovative national health financing intervention in Kenya; the health sector services fund (HSSF). In HSSF, central funds are credited directly into a facility’s bank account quarterly, and facility funds are managed by health facility management committees (HFMCs) including community representatives. HSSF is therefore a finance mechanism with potential to increase access to funds for peripheral facilities, support user fee reduction and improve equity in access. We conducted a process evaluation of HSSF implementation based on a theory of change underpinning the intervention. Methods included interviews at national, district and facility levels, facility record reviews, a structured exit survey and a document review. We found impressive achievements: HSSF funds were reaching facilities; funds were being overseen and used in a way that strengthened transparency and community involvement; and health workers’ motivation and patient satisfaction improved. Challenges or unintended outcomes included: complex and centralized accounting requirements undermining efficiency; interactions between HSSF and user fees leading to difficulties in accessing crucial user fee funds; and some relationship problems between key players. Although user fees charged had not increased, national reduction policies were still not being adhered to. Finance mechanisms can have a strong positive impact on peripheral facilities, and HFMCs can play a valuable role in managing facilities. Although fiduciary oversight is essential, mechanisms should allow for local decision-making and ensure that unmanageable paperwork is avoided. There are also limits to what can be achieved with relatively small funds in contexts of enormous need. Process evaluations tracking (un)intended consequences of interventions can contribute to regional financing and decentralization debates. PMID:25920355

2014-01-01

The purpose of this study was to explore correlates of sexual sensation seeking (SSS) in a sample of rural African American cocaine users. Respondent-driven sampling was used to recruit 251 participants from two impoverished rural counties in eastern Arkansas. Consistent with previous investigations, SSS scores were associated with being younger, being male, having more sexual partners, and having more unprotected sexual encounters in the previous 30 days. Multiple regression revealed SSS was correlated with number of oral sex acts, transactional sex (exchanging sex for food, shelter, drugs, money, or other commodities), and Addiction Severity Index (ASI) drug composite. SSS continues to demonstrate a strong association with sexual risk behaviors in diverse populations, including vulnerable groups like this community. Interventions to reduce unsafe sexual behaviors among high-risk groups, including drug users and individuals who engage in transactional sex, should incorporate approaches that include high sensation seekers' needs for novelty and variety.

Does contracting of health care in Afghanistan work? Public and service-users' perceptions and experience

PubMed Central

2011-01-01

Background In rebuilding devastated health services, the government of Afghanistan has provided access to basic services mainly by contracting with non-government organisations (NGOs), and more recently the Strengthening Mechanism (SM) of contracting with Provincial Health Offices. Community-based information about the public's views and experience of health services is scarce. Methods Field teams visited households in a stratified random sample of 30 communities in two districts in Kabul province, with health services mainly provided either by an NGO or through the SM and administered a questionnaire about household views, use, and experience of health services, including payments for services and corruption. They later discussed the findings with separate community focus groups of men and women. We calculated weighted frequencies of views and experience of services and multivariate analysis examined the related factors. Results The survey covered 3283 households including 2845 recent health service users. Some 42% of households in the SM district and 57% in the NGO district rated available health services as good. Some 63% of households in the SM district (adjacent to Kabul) and 93% in the NGO district ordinarily used government health facilities. Service users rated private facilities more positively than government facilities. Government service users were more satisfied in urban facilities, if the household head was not educated, if they had enough food in the last week, and if they waited less than 30 minutes. Many households were unwilling to comment on corruption in health services; 15% in the SM district and 26% in the NGO district reported having been asked for an unofficial payment. Despite a policy of free services, one in seven users paid for treatment in government facilities, and three in four paid for medicine outside the facilities. Focus groups confirmed people knew payments were unofficial; they were afraid to talk about corruption. Conclusions Households used government health services but preferred private services. The experience of service users was similar in the SM and NGO districts. People made unofficial payments in government facilities, whether SM or NGO run. Tackling corruption in health services is an important part of anti-corruption measures in Afghanistan. PMID:22376191

The Barrow area of northern Alaska is one of the most intensely researched locations in the Arctic and the Barrow Area Information Database (BAID, www.barrowmapped.org) tracks and facilitates a gamut of research, management, and educational activities in the area. BAID is a cyberinfrastructure (CI) that details much of the historic and extant research undertaken within in the Barrow region in a suite of interactive web-based mapping and information portals (geobrowsers). The BAID user community and target audience for BAID is diverse and includes research scientists, science logisticians, land managers, educators, students, and the general public. BAID contains information on more than 12,000 Barrow area research sites that extend back to the 1940's and more than 640 remote sensing images and geospatial datasets. In a web-based setting, users can zoom, pan, query, measure distance, save or print maps and query results, and filter or view information by space, time, and/or other tags. Additionally, data are described with metadata that meet Federal Geographic Data Committee standards. Recent advances include the addition of more than 2000 new research sites, the addition of a query builder user interface allowing rich and complex queries, and provision of differential global position system (dGPS) and high-resolution aerial imagery support to visiting scientists. Recent field surveys include over 80 miles of coastline to document rates of erosion and the collection of high-resolution sonar data for bathymetric mapping of Elson Lagoon and near shore region of the Chukchi Sea. A network of five climate stations has been deployed across the peninsula to serve as a wireless net for the research community and to deliver near real time climatic data to the user community. Local GIS personal have also been trained to better make use of scientific data for local decision making. Links to Barrow area datasets are housed at national data archives and substantial upgrades have been made to the BAID website and web mapping applications to include the public release of a new multi-temporal Imagery Viewer that allow users to interact with and compare imagery of the Barrow area from 1949 to present.

Multilabel user classification using the community structure of online networks

Papadopoulos, Symeon; Kompatsiaris, Yiannis

We study the problem of semi-supervised, multi-label user classification of networked data in the online social platform setting. We propose a framework that combines unsupervised community extraction and supervised, community-based feature weighting before training a classifier. We introduce Approximate Regularized Commute-Time Embedding (ARCTE), an algorithm that projects the users of a social graph onto a latent space, but instead of packing the global structure into a matrix of predefined rank, as many spectral and neural representation learning methods do, it extracts local communities for all users in the graph in order to learn a sparse embedding. To this end, we employ an improvement of personalized PageRank algorithms for searching locally in each user’s graph structure. Then, we perform supervised community feature weighting in order to boost the importance of highly predictive communities. We assess our method performance on the problem of user classification by performing an extensive comparative study among various recent methods based on graph embeddings. The comparison shows that ARCTE significantly outperforms the competition in almost all cases, achieving up to 35% relative improvement compared to the second best competing method in terms of F1-score.

Scanning hard X-ray imaging allows simultaneous acquisition of multimodal information, including X-ray fluorescence, absorption, phase and dark-field contrasts, providing structural and chemical details of the samples. Combining these scanning techniques with the infrastructure developed for fast data acquisition at Synchrotron Soleil permits to perform multimodal imaging and tomography during routine user experiments at the Nanoscopium beamline. A main challenge of such imaging techniques is the online processing and analysis of the generated very large volume (several hundreds of Giga Bytes) multimodal data-sets. This is especially important for the wide user community foreseen at the user oriented Nanoscopium beamline (e.g. from the fields of Biology, Life Sciences, Geology, Geobiology), having no experience in such data-handling. MMX-I is a new multi-platform open-source freeware for the processing and reconstruction of scanning multi-technique X-ray imaging and tomographic datasets. The MMX-I project aims to offer, both expert users and beginners, the possibility of processing and analysing raw data, either on-site or off-site. Therefore we have developed a multi-platform (Mac, Windows and Linux 64bit) data processing tool, which is easy to install, comprehensive, intuitive, extendable and user-friendly. MMX-I is now routinely used by the Nanoscopium user community and has demonstrated its performance in treating big data.

The GEOSS Science and Technology Stakeholder Network and Service Suite: Linking S&T Communities and GEOSS

2015-04-01

The Global Earth Observation System of Systems (GEOSS) developed by the Group on Earth Observations (GEO) aims to provide practice-relevant knowledge in support of decision making in a wide range of societal benefit areas. Generating this practice-relevant knowledge based on Earth observations, socio-economic data and models often depends on research, and utilization of the societal benefits of EOs requires the involvement of science and research communities. Building a GEOSS responding to the needs of a wide range of users necessitates contributions from many science and technology (S&T) communities. In particular, a strong engagement of science and technology (S&T) communities in both the development and use of GEOSS is necessary to address the complex issues associated with the on-going transition out of the Holocene. S&T support is needed to improve interoperability between global observing, modeling, and information systems; to enable data integration across disciplinary boundaries; to facilitate data sharing, archiving, dissemination, and reanalysis; to optimize the recording of observations, assimilation of data into models, and generation of data products; to enhance the value of observations from individual observing systems through their integration in the SBAs; and to harmonize well-calibrated, highly accurate, stable, sustained in-situ and satellite observations of the same variable recorded by different sensors and different agencies. Consequently, the GEO Work Plan includes several Tasks focusing on outreach to S&T communities, and most of the GEO Community of Practice have a strong S&T component. The GEOSS S&T Stakeholder Network facilitates input from S&T communities to GEO. Infrastructure serving and linking S&T users communities and GEOSS has been developed and is integrated into a GEOSS S&T Service Suite (GSTSS). The GSTSS has several outreach components for the demonstration of GEOSS and its value for S&T communities, and for services supporting S&T communities in their linkage to, and use of GEOSS. At the core of the GSTSS, the GEOSS S&T Portfolio includes examples showing GEOSS at work for S&T communities and provides an avenue for S&T groups to feature their contribution to GEOSS. The assessment of datasets is supported through an extensive feedback system. The User Requirements Registry (URR) allows users to publish what they do, how they do it, and what information and observations they need to do it. The URR is currently transitioned into a Socio-Economic and Environmental Information Needs Knowledge Base (SEE IN KB), which focuses on the linkage between societal goals and benefits on the one side and essential earth observations on the other side. The S&T Meeting Web Portal provides a workspace to coordinate and document GEO and GEOSS participation, side events, and presentations at relevant S&T meetings. The GEOSS S&T Stakeholder Network provides an umbrella for all S&T user and provider communities. The idea of a Stakeholder Network bringing together relevant S&T communities was developed by the EC-funded EGIDA project, and the underlying concept assumes that successful outreach to S&T communities requires demonstration of a benefit for these communities. The mission of the GEOSS S&T Stakeholder Network is twofold: to provide a voice for the needs and guidance of S&T communities to GEO, and to promote the use of GEOSS in these stakeholder communities. Workshops of the GEOSS S&T Stakeholder Network are organized within the GSTSS, among others with the goal to link societal goals, such as the Millennium Development Goals and the Sustainable Development Goals, and associated targets to a metric that then can be tied to essential variables to be provided by GEOSS.

Analysis and Visualization of Internet QA Bulletin Boards Represented as Heterogeneous Networks

Murata, Tsuyoshi; Ikeya, Tomoyuki

Visualizing and analyzing social interactions of CGM (Consumer Generated Media) are important for understanding overall activities on the internet. Social interactions are often represented as simple networks that are composed of homogeneous nodes and edges between them. However, related entities in real world are often not homogeneous. Such relations are naturally represented as heterogeneous networks composed of more than one kind of nodes and edges connecting them. In the case of CGM, for example, users and their contents constitute nodes of heterogeneous networks. There are related users (user communities) and related contents (contents communities) in the heterogeneous networks. Discovering both communities and finding correspondence among them will clarify the characteristics of the communites. This paper describes an attempt for visualizing and analyzing social interactions of Yahoo! Chiebukuro (Japanese Yahoo! Answers). New criteria for measuring correspondence between user communities and board communites are defined, and characteristics of both communities are analyzed using the criteria.

Background While overdose is a common cause of mortality among opioid injectors worldwide, little information exists on opioid overdoses or how context may influence overdose risk in Russia. This study sought to uncover social and structural aspects contributing to fatal overdose risk in St. Petersburg and assess prevention intervention feasibility. Methods Twenty-one key informant interviews were conducted with drug users, treatment providers, toxicologists, police, and ambulance staff. Thematic coding of interview content was conducted to elucidate elements of the overdose risk environment. Results Several factors within St. Petersburg’s environment were identified as shaping illicit drug users’ risk behaviors and contributing to conditions of suboptimal response to overdose in the community. Most drug users live and experience overdoses at home, where family and home environment may mediate or moderate risk behaviors. The overdose risk environment is also worsened by inefficient emergency response infrastructure, insufficient cardiopulmonary or naloxone training resources, and the preponderance of abstinence-based treatment approaches to the exclusion of other treatment modalities. However, attitudes of drug users and law enforcement officials generally support overdose prevention intervention feasibility. Modifiable aspects of the risk environment suggest community-based and structural interventions, including overdose response training for drug users and professionals that encompasses naloxone distribution to the users and equipping more ambulances with naloxone. Conclusion Local social and structural elements influence risk environments for overdose. Interventions at the community and structural levels to prevent and respond to opioid overdoses are needed for and integral to reducing overdose mortality in St. Petersburg. PMID:18774283

Addressing the needs of frequent users of emergency departments (EDs) is a health system priority in many jurisdictions. This study describes stakeholder perspectives on the implementation of a multi-organizational brief intervention designed to support integration and continuity of care for frequent ED users with mental health and addictions problems, focusing on perceived barriers and facilitators to early implementation in a large urban centre. Coordinating Access to Care from Hospital Emergency Departments (CATCH-ED) is a brief case management intervention bridging hospital, primary and community care for frequent ED users experiencing mental illness and addictions. To examine barriers and facilitators to early implementation of this multi-organizational intervention, between July and October 2012, 47 stakeholders, including direct service providers, managers and administrators participated in 32 semi-structured qualitative interviews and one focus group exploring their experience with the intervention and factors that helped or hindered successful early implementation. Qualitative data were analyzed using thematic analysis. Stakeholders valued the intervention and its potential to support continuity of care for this population. Service delivery system factors, including organizational capacity and a history of collaborative relationships across the healthcare continuum, and support system factors, such as training and supervision, emerged as key facilitators of program implementation. Operational challenges included early low program referral rates, management of a multi-organizational initiative, variable adherence to the model among participating organizations, and scant access to specialty psychiatric resources. Factors contributing to these challenges included lack of dedicated staff in the ED and limited local system capacity to support this population, and insufficient training and technical assistance available to participating organizations. A multi-organizational brief intervention is an acceptable model to support integration of hospital, primary and community care for frequent ED users. The study highlights the importance of early implementation evaluation to identify potential solutions to implementation barriers that may be applicable to many jurisdictions.

Objective This study explores the presence and actions of an electronic cigarette (e-cigarette) brand, Blu, on Twitter to observe how marketing messages are sent and diffused through the retweet (i.e., message forwarding) functionality. Retweet networks enable messages to reach additional Twitter users beyond the sender’s local network. We follow messages from their origin through multiple retweets to identify which messages have more reach, and the different users who are exposed. Methods We collected three months of publicly available data from Twitter. A combination of techniques in social network analysis and content analysis were applied to determine the various networks of users who are exposed to e-cigarette messages and how the retweet network can affect which messages spread. Results The Blu retweet network expanded during the study period. Analysis of user profiles combined with network cluster analysis showed that messages of certain topics were only circulated within a community of e-cigarette supporters, while other topics spread further, reaching more general Twitter users who may not support or use e-cigarettes. Conclusions Retweet networks can serve as proxy filters for marketing messages, as Twitter users decide which messages they will continue to diffuse among their followers. As certain e-cigarette messages extend beyond their point of origin, the audience being exposed expands beyond the e-cigarette community. Potential implications for health education campaigns include utilizing Twitter and targeting important gatekeepers or hubs that would maximize message diffusion. PMID:26684746

ECS DAAC Data Pools

Kiebuzinski, A. B.; Bories, C. M.; Kalluri, S.

2002-12-01

As part of its Earth Observing System (EOS), NASA supports operations for several satellites including Landsat 7, Terra, and Aqua. ECS (EOSDIS Core System) is a vast archival and distribution system and includes several Distributed Active Archive Centers (DAACs) located around the United States. EOSDIS reached a milestone in February when its data holdings exceeded one petabyte (1,000 terabytes) in size. It has been operational since 1999 and originally was intended to serve a large community of Earth Science researchers studying global climate change. The Synergy Program was initiated in 2000 with the purpose of exploring and expanding the use of remote sensing data beyond the traditional research community to the applications community including natural resource managers, disaster/emergency managers, urban planners and others. This included facilitating data access at the DAACs to enable non-researchers to exploit the data for their specific applications. The combined volume of data archived daily across the DAACs is of the order of three terabytes. These archived data are made available to the research community and to general users of ECS data. Currently, the average data volume distributed daily is two terabytes, which combined with an ever-increasing need for timely access to these data, taxes the ECS processing and archival resources for more real-time use than was previously intended for research purposes. As a result, the delivery of data sets to users was being delayed in many cases, to unacceptable limits. Raytheon, under the auspices of the Synergy Program, investigated methods at making data more accessible at a lower cost of resources (processing and archival) at the DAACs. Large on-line caches (as big as 70 Terabytes) of data were determined to be a solution that would allow users who require contemporary data to access them without having to pull it from the archive. These on-line caches are referred to as "Data Pools." In the Data Pool concept, data is inserted via subscriptions based on ECS events, for example, arrival of data matching a specific spatial context. Upon acquisition, these data are written to the Data Pools as well as to the permanent archive. The data is then accessed via a public Web interface, which provides a drilldown search, using data group, spatial, temporal and other flags. The result set is displayed as a list of ftp links to the data, which the user can click and directly download. Data Pool holdings are continuously renewed as the data is allowed to expire and is replaced by more current insertions. In addition, the Data Pool may also house data sets that though not contemporary, receive significant user attention, i.e. a Chernobyl-type of incident, a flood, or a forest fire. The benefits are that users who require contemporary data can access the data immediately (within 24 hours of acquisition) under a much improved access technique. Users not requiring contemporary data, benefit from the Data Pools by having greater archival and processing resources (and a shorter processing queue) made available to them. All users benefit now from the capability to have standing data orders for data matching a geographic context (spatial subscription), a capability also developed under the Synergy program. The Data Pools are currently being installed and checked at each of the DAACs. Additionally, several improvements to the search capabilities, data manipulation tools and overall storage capacity are being developed and will be installed in the First Quarter of 2003.

Facilitation of service user participation in the co-production of mental healthcare planning and service delivery is an integral component of contemporary mental health policy and clinical guidelines. However, many service users continue to experience exclusion from the planning of their care. This review synthesizes qualitative research about participation in mental healthcare and articulates essential processes that enable service user participation in mental health care. Electronic databases were systematically searched. Studies were included if they were peer reviewed qualitative studies, published between 2000 and 2015, examining participation in mental health care. The Critical Appraisal Skills Program checklist was used to assess the quality of each included study. Constant comparison was used to identify similar constructs across several studies, which were then abstracted into thematic constructs. The synthesis resulted in the identification of six principal themes, which articulate key processes that facilitate service user participation in mental healthcare. These themes included: exercising influence; tokenism; sharing knowledge; lacking capacity; respect; and empathy. This meta-synthesis demonstrates that service user participation in mental healthcare remains a policy aspiration, which generally has not been translated into clinical practice. The continued lack of impact on policy on the delivery of mental healthcare suggests that change may have to be community driven. Systemic service user advocacy groups could contribute critically to promoting authentic service user participation in the co-production of mental health services.

Lynch, Vickie E; Chen, Meili; Cobb, John W

The unique contributions of the Neutron Science TeraGrid Gateway (NSTG) are the connection of national user facility instrument data sources to the integrated cyberinfrastructure of the National Science FoundationTeraGrid and the development of a neutron science gateway that allows neutron scientists to use TeraGrid resources to analyze their data, including comparison of experiment with simulation. The NSTG is working in close collaboration with the Spallation Neutron Source (SNS) at Oak Ridge as their principal facility partner. The SNS is a next-generation neutron source. It has completed construction at a cost of $1.4 billion and is ramping up operations. The SNSmore » will provide an order of magnitude greater flux than any previous facility in the world and will be available to all of the nation's scientists, independent of funding source, on a peer-reviewed merit basis. With this new capability, the neutron science community is facing orders of magnitude larger data sets and is at a critical point for data analysis and simulation. There is a recognized need for new ways to manage and analyze data to optimize both beam time and scientific output. The TeraGrid is providing new capabilities in the gateway for simulations using McStas and a fitting service on distributed TeraGrid resources to improved turnaround. NSTG staff are also exploring replicating experimental data in archival storage. As part of the SNS partnership, the NSTG provides access to gateway support, cyberinfrastructure outreach, community development, and user support for the neutron science community. This community includes not only SNS staff and users but extends to all the major worldwide neutron scattering centers.« less

WPA President M. Maj established the Task Force on Best Practice in Working with Service Users and Carers in 2008, chaired by H. Herrman. The Task Force had the remit to create recommendations for the international mental health community on how to develop successful partnership working. The work began with a review of literature on service user and carer involvement and partnership. This set out a range of considerations for good practice, including choice of appropriate terminology, clarifying the partnership process and identifying and reducing barriers to partnership working. Based on the literature review and on the shared knowledge in the Task Force, a set of ten recommendations for good practice was developed. These recommendations were the basis for a worldwide consultation of stakeholders with expertise as service users, families and carers, and the WPA Board and Council. The results showed a strong consensus across the international mental health community on the ten recommendations, with the strongest agreement coming from service users and carers. This general consensus gives a basis for Task Force plans to seek support for activities to promote shared work worldwide to identify best practice examples and create a resource to assist others to begin successful collaboration.

Objective To investigate the predictors of early and late dropout among community users of the MoodGYM website, a five module online intervention for reducing the symptoms of depression. Method Approximately 82,000 users accessed the site in 2006, of which 27% completed one module and 10% completed two or more modules. Adherence was modeled as a trichotomous variable representing non-starters (0 modules), early dropouts (1 module) and late dropouts (2–5 modules). Predictor variables included age, gender, education, location, referral source, depression severity, anxiety severity, dysfunctional thinking, and change in symptom count. Results Better adherence was predicted by higher depression severity, higher anxiety severity, a greater level of dysfunctional thinking, younger age, higher education, being female, and being referred to the site by a mental health professional. In addition, users whose depression severity had improved or remained stable after the first intervention module had higher odds of completing subsequent modules. Conclusions While the effect of age and the null effect of location were in accordance with prior adherence research, the significant effects of gender, education and depression severity were not, and may reflect user characteristics, the content of the intervention and unique aspects of online interventions. Further research directions are suggested to investigate the elements of open access online interventions that facilitate adherence. PMID:19920949

The Family Health Strategy should be focused on the family unit and constructed operationally within the community sphere. The research assessed the family focus and community orientation as attributes of Primary Health Care, comparing if the responses differed among users, professionals and managers. It is an evaluative study of a population-based quantitative approach conducted between January 2010 and March 2011 in São Luís in the state of Maranhão. The study involved a population of 32 managers and 80 professionals with more than six months experience in the Family Health Strategy, and 883 users were selected by means of cluster sampling. Questionnaires validated in Brazil were used based on the components of the Primary Care Assessment Tool (PCATool). The composite index of the family focus was 2.7 for users, 4.9 for professionals and 5.3 for managers. In the posttest phase, differences were detected between users and professionals, and users and managers. The composite index of community orientation was 2.9 for users, 3.9 for professionals and 4.8 for managers (p < 0.001). Managers attributed higher percentages in all indicators, followed by professionals and lastly users. Both attributes were rated as being unsatisfactory in the perception of the users.

An incremental community detection method for social tagging systems using locality-sensitive hashing.

PubMed

Wu, Zhenyu; Zou, Ming

2014-10-01

An increasing number of users interact, collaborate, and share information through social networks. Unprecedented growth in social networks is generating a significant amount of unstructured social data. From such data, distilling communities where users have common interests and tracking variations of users' interests over time are important research tracks in fields such as opinion mining, trend prediction, and personalized services. However, these tasks are extremely difficult considering the highly dynamic characteristics of the data. Existing community detection methods are time consuming, making it difficult to process data in real time. In this paper, dynamic unstructured data is modeled as a stream. Tag assignments stream clustering (TASC), an incremental scalable community detection method, is proposed based on locality-sensitive hashing. Both tags and latent interactions among users are incorporated in the method. In our experiments, the social dynamic behaviors of users are first analyzed. The proposed TASC method is then compared with state-of-the-art clustering methods such as StreamKmeans and incremental k-clique; results indicate that TASC can detect communities more efficiently and effectively.

Background Although skilled birth care contributes significantly to the prevention of maternal and newborn morbidity and mortality, utilization of such care is poor in mid- and far-western Nepal. This study explored the perceptions of service users and providers regarding barriers to skilled birth care. Design We conducted 24 focus group discussions, 12 each with service users and service providers from different health institutions in mid- and far-western Nepal. All discussions examined the perceptions and experiences of service users and providers regarding barriers to skilled birth care and explored possible solutions to overcoming such barriers. Results Our results determined that major barriers to skilled birth care include inadequate knowledge of the importance of services offered by skilled birth attendants (SBAs), distance to health facilities, unavailability of transport services, and poor availability of SBAs. Other barriers included poor infrastructure, meager services, inadequate information about services/facilities, cultural practices and beliefs, and low prioritization of birth care. Moreover, the tradition of isolating women during and after childbirth decreased the likelihood that women would utilize delivery care services at health facilities. Conclusions Service users and providers perceived inadequate availability and accessibility of skilled birth care in remote areas of Nepal, and overall utilization of these services was poor. Therefore, training and recruiting locally available health workers, helping community groups establish transport mechanisms, upgrading physical facilities and services at health institutions, and increasing community awareness of the importance of skilled birth care will help bridge these gaps.

Preserving data is not only a technical challenge. Perhaps the best way to protect data is to use it. Grassroots efforts to make research-quality copies of federal data continue to energize communities of data users who often did not previously recognize themselves as open earth data users. Beyond "data rescue" events, the Data Refuge project researches how federal climate and environmental data are used downstream in a variety of local communities and municipal governments to address everyday issues: public health, municipal safety, and even the preservation of cultural heritage assets. Documenting the diverse uses made of open earth data beyond the earth sciences research community grows the community who, in making use of data, also helps to preserve it.

In this paper we report our investigation into how using and interacting with a local festival mobile app enhanced users’ festival experiences and connected them to other local users and their community. We explored the relationship between users’ perceived basic affordances of mobile technology, perceived opportunities of the festival app, and three elements that sustain the local community — attachment, engagement, and social support networks. Based on the usage logs of 348 active users, as well as survey responses from 80 users, we present a mobile-mediated local community framework and found that engagement is a key mediator of mobile experiencesmore » and facets of community.« less

Human perceptual deficits as factors in computer interface test and evaluation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bowser, S.E.

1992-06-01

Issues related to testing and evaluating human computer interfaces are usually based on the machine rather than on the human portion of the computer interface. Perceptual characteristics of the expected user are rarely investigated, and interface designers ignore known population perceptual limitations. For these reasons, environmental impacts on the equipment will more likely be defined than will user perceptual characteristics. The investigation of user population characteristics is most often directed toward intellectual abilities and anthropometry. This problem is compounded by the fact that some deficits capabilities tend to be found in higher-than-overall population distribution in some user groups. The testmore » and evaluation community can address the issue from two primary aspects. First, assessing user characteristics should be extended to include tests of perceptual capability. Secondly, interface designs should use multimode information coding.« less

2018-01-05

Traditional survey methods are limited in the study of hidden populations due to the hard to access properties, including lack of a sampling frame, sensitivity issue, reporting error, small sample size, etc. The rapid increase of online communities, of which members interact with others via the Internet, have generated large amounts of data, offering new opportunities for understanding hidden populations with unprecedented sample sizes and richness of information. In this study, we try to understand the multidimensional characteristics of a hidden population by analyzing the massive data generated in the online community. By elaborately designing crawlers, we retrieved a complete dataset from the "HIV bar," the largest bar related to HIV on the Baidu Tieba platform, for all records from January 2005 to August 2016. Through natural language processing and social network analysis, we explored the psychology, behavior and demand of online HIV population and examined the network community structure. In HIV communities, the average topic similarity among members is positively correlated to network efficiency (r = 0.70, p < 0.001), indicating that the closer the social distance between members of the community, the more similar their topics. The proportion of negative users in each community is around 60%, weakly correlated with community size (r = 0.25, p = 0.002). It is found that users suspecting initial HIV infection or first in contact with high-risk behaviors tend to seek help and advice on the social networking platform, rather than immediately going to a hospital for blood tests. Online communities have generated copious amounts of data offering new opportunities for understanding hidden populations with unprecedented sample sizes and richness of information. It is recommended that support through online services for HIV/AIDS consultation and diagnosis be improved to avoid privacy concerns and social discrimination in China.

Morgan, Kerri A; Engsberg, Jack R; Gray, David B

2017-01-01

The purpose of this project was to identify wheelchair skills currently being taught to new manual wheelchair users, identify areas of importance for manual wheelchair skills' training during initial rehabilitation, identify similarities and differences between the perspectives of health care professionals and manual wheelchair users and use the ICF to organize themes related to rehabilitation and learning how to use a manual wheelchair. Focus groups were conducted with health care professionals and experienced manual wheelchair users. ICF codes were used to identify focus group themes. The Activities and Participation codes were more frequently used than Structure, Function and Environment codes. Wheelchair skills identified as important for new manual wheelchair users included propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain. Health care professionals and manual wheelchair users identified the need to incorporate the environment (home and community) into the wheelchair training program. Identifying essential components for training the proper propulsion mechanics and wheelchair skills in new manual wheelchair users is an important step in preventing future health and participation restrictions. Implications for Rehabilitation Wheelchair skills are being addressed frequently during rehabilitation at the activity-dependent level. Propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain are important skills to address during wheelchair training. Environment factors (in the home and community) are important to incorporate into wheelchair training to maximize safe and multiple-environmental-setting uses of manual wheelchairs. The ICF has application to understanding manual wheelchair rehabilitation for wheelchair users and therapists for improving the understanding of manual wheelchair use.

The EPA's human exposure research program for assessing cumulative risk in communities.

Communities are faced with challenges in identifying and prioritizing environmental issues, taking actions to reduce their exposures, and determining their effectiveness for reducing human health risks. Additional challenges include determining what scientific tools are available and most relevant, and understanding how to use those tools; given these barriers, community groups tend to rely more on risk perception than science. The U.S. Environmental Protection Agency's Office of Research and Development, National Exposure Research Laboratory (NERL) and collaborators are developing and applying tools (models, data, methods) for enhancing cumulative risk assessments. The NERL's "Cumulative Communities Research Program" focuses on key science questions: (1) How to systematically identify and prioritize key chemical stressors within a given community?; (2) How to develop estimates of exposure to multiple stressors for individuals in epidemiologic studies?; and (3) What tools can be used to assess community-level distributions of exposures for the development and evaluation of the effectiveness of risk reduction strategies? This paper provides community partners and scientific researchers with an understanding of the NERL research program and other efforts to address cumulative community risks; and key research needs and opportunities. Some initial findings include the following: (1) Many useful tools exist for components of risk assessment, but need to be developed collaboratively with end users and made more comprehensive and user-friendly for practical application; (2) Tools for quantifying cumulative risks and impact of community risk reduction activities are also needed; (3) More data are needed to assess community- and individual-level exposures, and to link exposure-related information with health effects; and (4) Additional research is needed to incorporate risk-modifying factors ("non-chemical stressors") into cumulative risk assessments. The products of this research program will advance the science for cumulative risk assessments and empower communities with information so that they can make informed, cost-effective decisions to improve public health.

A power information user (PIU) model to promote information integration in Tennessee's public health community.

Observation and immersion in the user community are critical factors in designing and implementing informatics solutions; such practices ensure relevant interventions and promote user acceptance. Libraries can adapt these strategies to developing instruction and outreach. While needs assessment is typically a core facet of library instruction, sustained, iterative assessment underlying the development of user-centered instruction is key to integrating resource use into the workflow. This paper describes the Eskind Biomedical Library's (EBL's) recent work with the Tennessee public health community to articulate a training model centered around developing power information users (PIUs). PIUs are community-based individuals with an advanced understanding of information seeking and resource use and are committed to championing information integration. As model development was informed by observation of PIU workflow and information needs, it also allowed for informal testing of the applicability of assessment via domain immersion in library outreach. Though the number of PIUs involved in the project was small, evaluation indicated that the model was useful for promoting information use in PIU workgroups and that the concept of domain immersion was relevant to library-related projects. Moreover, EBL continues to employ principles of domain understanding inherent in the PIU model to develop further interventions for the public health community and library users.

The adoption of Firm-Hosted Online Communities: an empirical investigation into the role of service quality and social interactions

Online communities are a powerful device for collaborative creativity and innovation. Developments in Web 2.0 technologies have given rise to such interactions through firm-hosted online communities (FHOCs) - firm-run online information services that also provide self-help to a community. We devise a model that seeks to explain the factors that encourage people to become members of a FHOC and test the model using structural equation modelling based on data collected from 511 users of a FHOC. The study finds that: (a) an understanding of Perceived Usefulness (PU) plays a mediating role between Behavioural Intention (BI) to adopt FHOC and Trust, as well as Interface design; b) Networking among users has an indirect effect on BI; and c) design of the Interface has a direct influence on BI. A managerial implication is that Networking plays a role in the way supplementary services, including blogs and discussion forums, are perceived. Theoretically, when service quality is decomposed into components such as core services and supplementary services, it also positively influences PU.

Reducing substance use and risky sexual behaviour among drug users in Durban, South Africa: Assessing the impact of community-level risk-reduction interventions.

PubMed

Parry, C D H; Carney, T; Petersen Williams, P

2017-12-01

Alcohol and other drug (AOD) use is increasingly recognised as having a direct and indirect effect on the transmission of human immunodeficiency virus (HIV). However, there is evidence to suggest that drug- and sex-related HIV risk-reduction interventions targeted at drug users within drug treatment centres or via community outreach efforts can lead to positive health outcomes. This study aimed to test whether a community-level intervention aimed at AOD users has an impact on risky AOD use and sexual risk behaviour. In 2007, in collaboration with a local non-governmental organisation (NGO) in Durban, an initiative was begun to implement a number of harm reduction strategies for injection and non-injection drug users. The NGO recruited peer outreach workers who received intensive initial training, which was followed by six-monthly monitoring and evaluation of their performance. Participants had to be 16 years of age or older, and self-reported alcohol and/or drug users. Peer outreach workers completed a face-to-face baseline questionnaire with participants which recorded risk behaviours and a risk-reduction plan was developed with participants which consisted of reducing injection (if applicable) and non-injection drug use and sex-related risks. Other components of the intervention included distribution of condoms, risk-reduction counselling, expanded access to HIV Testing Services, HIV/sexually transmitted infection care and treatment, and referrals to substance abuse treatment and social services. At follow-up, the baseline questionnaire was completed again and participants were also asked the frequency of reducing identified risk behaviours. Baseline information was collected from 138 drug users recruited into the study through community-based outreach, and who were subsequently followed up between 2010 and 2012. No injection drug users were reached. The data presented here are for first contact (baseline) and the final follow-up contact with the participants. There were no decreases in drug use practices such as use of cannabis, heroin, cocaine and Ecstasy after the intervention with drug users; however, there was a significant reduction in alcohol use following the intervention. While there was a substantial increase in the proportion of participants using drugs daily as opposed to more often, the reduction in the frequency of drug use was not statistically significant. Following the intervention, drug users had significantly fewer sexual partners, but there were no significant differences following the intervention with regard to frequency of sex or use of condoms. Substance use in general and during sex was, however, decreased. While the findings were mixed, the study shows that it is possible to provide HIV risk-reduction services to a population of substance users who are less likely to receive services through community outreach, and provide risk-reduction information, condoms and condom demonstration and other services. More intensive interventions might be needed to have a substantial impact on substance use and substance use-related HIV risk behaviours.

Social media can provide a resource for characterizing communities and small populations through activities and content shared online. For instance, studying the language use in social media within military populations may provide insights into their health and wellbeing. In this paper, we address three research questions: (1) How do military populations use social media? (2) What do military users discuss in social media? And (3) Do military users talk about health and well-being differently than civilians? Military Twitter users were identified through keywords in the profile description of users who posted geo-tagged tweets at military installations. The data was anonymizedmore » for the analysis. User profiles that belong to military population were compared to the nonmilitary population. Our results indicate that military users talk more about events in their military life, whereas nonmilitary users talk more about school, work, and leisure activities. We also found that the online content generated by both populations is significantly different, including health-related language and communication behavior.« less

The US Geological Survey (USGS) Land Remote Sensing Program (LRSP) has collected user requirements from a range of applications to help formulate the Landsat 9 follow-on mission (Landsat 10) through the Requirements, Capabilities and Analysis (RCA) activity. The USGS is working with NASA to develop Landsat 10, which is scheduled to launch in the 2027 timeframe as part of the Sustainable Land Imaging program. User requirements collected through RCA will help inform future Landsat 10 sensor designs and mission characteristics. Current Federal civil community users have provided hundreds of requirements through systematic, in-depth interviews. Academic, State, local, industry, and international Landsat user community input was also incorporated in the process. Emphasis was placed on spatial resolution, temporal revisit, and spectral characteristics, as well as other aspects such as accuracy, continuity, sampling condition, data access and format. We will provide an overview of the Landsat 10 user requirements collection process and summary results of user needs from the broad land imagining community.

Research about service user involvement in research and education focuses on the purpose, the methods, the barriers and the impact of their involvement. Few studies report on the experience of the service users who get involved. This paper reports an exploration of the experience of service users who participated in an interprofessional educational initiative in primary care - the Learning to Improve the Management of Back Pain in the Community (LIMBIC) project. Service users attended workshops with practice teams and assisted them in developing small scale quality improvement projects to improve their provision of care for people with back pain. To explore the experience of service users involved in the LIMBIC project. Using the philosophical and methodological approaches of pragmatism this study analysed data from the wider LIMBIC project and collected primary data through semi structured interviews with service users. Secondary data were reanalysed and integrated with primary data to address the research question. The study was undertaken in the primary health care setting. Patients participated as service users in workshops and quality improvement projects with members from their practice teams. Interviews with service users were transcribed and analysed thematically. Document and thematic analyses of secondary data from the LIMBIC project included focus group transcripts, patient stories, film, emails, meeting notes, a wiki and educational material such as presentations. Themes identified through the analyses illustrated the importance, to the service users, of the sense of community, of clear communication, and of influencing change through involvement. A model for co-learning with service users resulted from the analyses. The experience of service users can be optimised by planning, preparation and support so that their wealth of expertise can be recognised and utilised. A model for co-learning was developed and is presented in this paper. Copyright © 2014 Elsevier Ltd. All rights reserved.

The NASA Regional Planetary Image Facility (RPIF) Network: A Key Resource for Accessing and Using Planetary Spatial Data

NASA Astrophysics Data System (ADS)

Hagerty, J. J.

2017-12-01

The role of the NASA Regional Planetary Image Facility (RPIF) Network is evolving as new science-ready spatial data products continue to be created and as key historical planetary data sets are digitized. Specifically, the RPIF Network is poised to serve specialized knowledge and services in a user-friendly manner that removes most barriers to locating, accessing, and exploiting planetary spatial data, thus providing a critical data access role within a spatial data infrastructure. The goal of the Network is to provide support and training to a broad audience of planetary spatial data users. In an effort to meet the planetary science community's evolving needs, we are focusing on the following objectives: Maintain and improve the delivery of historical data accumulated over the past four decades so as not to lose critical, historical information. This is being achieved by systematically digitizing fragile materials, allowing increased access and preserving them at the same time. Help users locate, access, visualize, and exploit planetary science data. Many of the facilities have begun to establish Guest User Facilities that allow researchers to use and/or be trained on GIS equipment and other specialized tools like Socet Set/GXP photogrammetry workstations for generating digital elevation maps. Improve the connection between the Network nodes while also leveraging the unique resources of each node. To achieve this goal, each facility is developing and sharing searchable databases of their collections, including robust metadata in a standards compliant way. Communicate more effectively and regularly with the planetary science community in an effort to make potential users aware of resources and services provided by the Network, while also engaging community members in discussions about community needs. Provide a regional resource for the science community, colleges, universities, museums, media, and the public to access planetary data. Introduce new strategies for visualizing planetary data and products (e.g., 3D printing and virtual reality platforms/experiences). We anticipate that in a few years virtual reality tools will be an integral part of data analysis, providing more intuitive understanding of multiple complex data sets.

DIRAC, the LHCb community Grid solution, was considerably reengineered in order to meet all the requirements for processing the data coming from the LHCb experiment. It is covering all the tasks starting with raw data transportation from the experiment area to the grid storage, data processing up to the final user analysis. The reengineered DIRAC3 version of the system includes a fully grid security compliant framework for building service oriented distributed systems; complete Pilot Job framework for creating efficient workload management systems; several subsystems to manage high level operations like data production and distribution management. The user interfaces of the DIRAC3 system providing rich command line and scripting tools are complemented by a full-featured Web portal providing users with a secure access to all the details of the system status and ongoing activities. We will present an overview of the DIRAC3 architecture, new innovative features and the achieved performance. Extending DIRAC3 to manage computing resources beyond the WLCG grid will be discussed. Experience with using DIRAC3 by other user communities than LHCb and in other application domains than High Energy Physics will be shown to demonstrate the general-purpose nature of the system.

The article presents an analysis of the use of focus groups in researching community mental health users, starting with the reasons for using them, their implementation in mental health service users' research, and the adaptations of focus group use when researching the experiences of users. Based on personal research experience and a review of scientific publications in the Google Scholar, Web of Science, ProQuest, EBSCOhost, and Scopus databases, 20 articles published between 2010 and 2016 were selected for targeted content analysis. A checklist for reporting on the use of focus groups with community mental health service users, aiming to improve the comparability, verifiability and validity was developed. Adaptations of the implementation of focus groups in relation to participants' characteristics were suggested. Focus groups are not only useful as a scientific research technique, but also for ensuring service users' participation in decision-making in community mental health and evaluating the quality of the mental health system and services .

Assessment of Soil Moisture Data Requirements by the Potential SMAP Data User Community: Review of SMAP Mission User Community

NASA Technical Reports Server (NTRS)

Brown, Molly E.; Escobar, Vanessa M.

2013-01-01

NASA's Soil Moisture Active and Passive (SMAP) mission is planned for launch in October 2014 and will provide global measurements of soil moisture and freeze thaw state. The project is driven by both basic research and applied science goals. Understanding how application driven end-users will apply SMAP data, prior to the satellite's launch, is an important goal of NASA's applied science program and SMAP mission success. Because SMAP data are unique, there are no direct proxy data sets that can be used in research and operational studies to determine how the data will interact with existing processes. The objective of this study is to solicit data requirements, accuracy needs, and current understanding of the SMAP mission from the potential user community. This study showed that the data to be provided by the SMAP mission did substantially meet the user community needs. Although there was a broad distribution of requirements stated, the SMAP mission fit within these requirements.

The current analysis examines whether opioid use is associated with insomnia in a community sample, as the consequences of the growing epidemic of prescription opioid use continue to cause public health concern. A cross-sectional study including 8433 members in a community outreach program, HealthStreet, in Northeast Florida. Community Health Workers (CHWs) assessed health information, including use of opioids (i.e., Vicodin®, Oxycodone, Codeine, Demerol®, Morphine, Percocet®, Darvon®, Hydrocodone) from community members during field outreach. Insomnia was determined based on self-report: "Have you ever been told you had, or have you ever had a problem with insomnia?" Summary descriptive statistics were calculated and logistic regression modeling was used to calculate adjusted odds ratios (ORs) with 95% confidence intervals for insomnia, by opioid use status, after adjustment for demographics and other covariates. Among 8433 community members recruited (41% male; 61% Black), 2115 (25%) reported insomnia, and 4200 (50.3%) reported use of opioids. After adjusting for covariates, opioid users were significantly more likely to report insomnia than non-users (adjusted OR, 1.42; 95% CI, 1.25-1.61). Insomnia was 42% more likely among those who reported using prescription opioids compared to those who did not. With one half of the sample reporting prescription opioid use, and a fourth reporting insomnia, it is important to further investigate the relationship between the two. Findings provide useful preliminary information from which to conduct further analyses. Copyright © 2017 National Sleep Foundation. Published by Elsevier Inc. All rights reserved.

Operating the EOSDIS at the land processes DAAC managing expectations, requirements, and performance across agencies, missions, instruments, systems, and user communities

NASA developed the Earth Observing System (EOS) during the 1990'S. At the Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS EROS Data Center, the EOS Data and Information System (EOSDIS) is required to support heritage missions as well as Landsat 7, Terra, and Aqua. The original system concept of the early 1990'S changed as each community had its say - first the managers, then engineers, scientists, developers, operators, and then finally the general public. The systems at the LP DAAC - particularly the largest single system, the EOSDIS Core System (ECS) - are changing as experience accumulates, technology changes, and each user group gains influence. The LP DAAC has adapted as contingencies were planned for, requirements and therefore plans were modified, and expectations changed faster than requirements could hope to be satisfied. Although not responsible for Quality Assurance of the science data, the LP DAAC works to ensure the data are accessible and useable by influencing systems, capabilities, and data formats where possible, and providing tools and user support as necessary. While supporting multiple missions and instruments, the LP DAAC also works with and learns from multiple management and oversight groups as they review mission requirements, system capabilities, and the overall operation of the LP DAAC. Stakeholders, including the Land Science community, are consulted regularly to ensure that the LP DAAC remains cognizant and responsive to the evolving needs of the user community. Today, the systems do not look or function as originally planned, but they do work, and they allow customers to search and order of an impressive amount of diverse data.

ESA has established a Planetary Science Archive User Group (PSA-UG), with the task of offering independent advice to ESA's Planetary Science Archive (e.g. Heather et al., 2013). The PSA-UG is an official and independent body that continuously evaluates services and tools provided by the PSA to the community of planetary data scientific users. The group has been tasked with the following top level objectives: a) Advise ESA on future development of the PSA. b) Act as a focus for the interests of the scientific community. c) Act as an advocate for the PSA. d) Monitor the PSA activities. Based on this, the PSA-UG will report through the official ESA channels. Disciplines and subjects represented by PSA-UG members include: Remote Sensing of both Atmosphere and Solid Surfaces, Magnetospheres, Plasmas, Radio Science and Auxilliary data. The composition of the group covers ESA missions populating the PSA both now and in the near future. The first members of the PSA-UG were selected in 2013 and will serve for 3 years, until 2016. The PSA-UG will address the community through workshops, conferences and the internet. Written recommendations will be made to the PSA coordinator, and an annual report on PSA and the PSA-UG activities will be sent to the Solar System Exploration Working Group (SSEWG). Any member of the community and planetary data user can get in touch with individual members of the PSA-UG or with the group as a whole via the contacts provided on the official PSA-UG web-page: http://archives.esac.esa.int/psa/psa-ug The PSA is accessible via: http://archives.esac.esa.int/psa

Numerous publications demonstrate the importance of community-based participatory research (CBPR) in community health research, but few target the Deaf community. The Deaf community is understudied and underrepresented in health research despite suspected health disparities and communication barriers. The goal of this paper is to share the lessons learned from the implementation of CBPR in an understudied community of Deaf American Sign Language (ASL) users in the greater Rochester, New York, area. We review the process of CBPR in a Deaf ASL community and identify the lessons learned. Key CBPR lessons include the importance of engaging and educating the community about research, ensuring that research benefits the community, using peer-based recruitment strategies, and sustaining community partnerships. These lessons informed subsequent research activities. This report focuses on the use of CBPR principles in a Deaf ASL population; lessons learned can be applied to research with other challenging-to-reach populations.

We investigated the knowledge and characteristics of herbal supplement usage of the customers of community pharmacies in a Malaysian population. Self-administered questionnaires (in English, Malay, or Chinese) were provided to customers at three community pharmacies in Malaysia (Ipoh, Perak). Questionnaire validation and translation validation were performed. A pilot study was conducted before actual questionnaire distribution. Informed consent was obtained from all participants. Total number of participants was 270 (99 males and 171 females) with majority from the 31-50 age group (41.5%). Among the participants, 45.6% were herbal users. The most commonly used herbal supplements were evening primrose oil (17.9%), ginkgo biloba (13.0%), and milk thistle (8.5%). The participants seemed to have sufficient knowledge regarding herbal supplements including safety, quality, and indication of use from medical literature. Participants obtained information about herbal supplements from pharmacists (26.9%), package inserts (25.2%), friends (20.5%), and the Internet (13.3%) more often than from their doctors (9.8%). Most herbal users did not inform their doctors about their usage of herbal supplements (68.3%) or the side effects (61.5%). Herbal supplement users also tended to be women, >50-year-old, and those with higher monthly household incomes. Community pharmacists have a vital role in educating their customers about the safe use of herbal supplements. The participants had sufficient knowledge about herbal supplement usage; therefore, customers of these community pharmacies may have benefitted from the advice of the pharmacists. Further studies could be carried out in future on the knowledge, skills and roles of community pharmacists in the safe use of herbal supplements. Copyright © 2017 Elsevier Ltd. All rights reserved.

Data publication and sharing using the SciDrive service

Mishin, Dmitry; Medvedev, D.; Szalay, A. S.; Plante, R. L.

2014-01-01

Despite the last years progress in scientific data storage, still remains the problem of public data storage and sharing system for relatively small scientific datasets. These are collections forming the “long tail” of power log datasets distribution. The aggregated size of the long tail data is comparable to the size of all data collections from large archives, and the value of data is significant. The SciDrive project's main goal is providing the scientific community with a place to reliably and freely store such data and provide access to it to broad scientific community. The primary target audience of the project is astoromy community, and it will be extended to other fields. We're aiming to create a simple way of publishing a dataset, which can be then shared with other people. Data owner controls the permissions to modify and access the data and can assign a group of users or open the access to everyone. The data contained in the dataset will be automaticaly recognized by a background process. Known data formats will be extracted according to the user's settings. Currently tabular data can be automatically extracted to the user's MyDB table where user can make SQL queries to the dataset and merge it with other public CasJobs resources. Other data formats can be processed using a set of plugins that upload the data or metadata to user-defined side services. The current implementation targets some of the data formats commonly used by the astronomy communities, including FITS, ASCII and Excel tables, TIFF images, and YT simulations data archives. Along with generic metadata, format-specific metadata is also processed. For example, basic information about celestial objects is extracted from FITS files and TIFF images, if present. A 100TB implementation has just been put into production at Johns Hopkins University. The system features public data storage REST service supporting VOSpace 2.0 and Dropbox protocols, HTML5 web portal, command-line client and Java standalone client to synchronize a local folder with the remote storage. We use VAO SSO (Single Sign On) service from NCSA for users authentication that provides free registration for everyone.

Recently online communities have attracted great interest and have become an important medium of information exchange between users. The aim of this work is to introduce a simple model of the evolution of online communities. This model describes (a) the time evolution of users' activity in a web service, e.g., the time evolution of the number of online friends or written posts, (b) the time evolution of the degree distribution of a social network, and (c) the time evolution of the number of active users of a web service. In the second part of the paper we investigate the influence of the users' lifespan (i.e., the total time in which they are active in an online community) on the process of rumor propagation in evolving social networks. Viral marketing is an important application of such method of information propagation.

2002-01-01

The last decade was a period of unprecedented acceptance of NASA developed electric propulsion by the user community. The benefits of high performance electric propulsion systems are now widely recognized, and new technologies have been accepted across the commonly. NASA clearly recognizes the need for new, high performance, electric propulsion technologies for future solar system missions and is sponsoring aggressive efforts in this area. These efforts are mainly conducted under the Office of Aerospace Technology. Plans over the next six years include the development of next generation ion thrusters for end of decade missions. Additional efforts are planned for the development of very high power thrusters, including magnetoplasmadynamic, pulsed inductive, and VASIMR, and clusters of Hall thrusters. In addition to the in-house technology efforts, NASA continues to work closely with both supplier and user communities to maximize the acceptance of new technology in a timely and cost-effective manner. This paper provides an overview of NASA's activities in the area of electric propulsion with an emphasis on future program directions.

The EVER-EST portal as support for the Sea Monitoring Virtual Research Community, through the sharing of resources, enabling dynamic collaboration and promoting community engagement

2017-04-01

EVER-EST offers a framework based on advanced services delivered both at the e-infrastructure and domain-specific level, with the objective of supporting each phase of the Earth Science Research and Information Lifecycle. It provides innovative e-research services to Earth Science user communities for communication, cross-validation and the sharing of knowledge and science outputs. The project follows a user-centric approach: real use cases taken from pre-selected Virtual Research Communities (VRC) covering different Earth Science research scenarios drive the implementation of the Virtual Research Environment (VRE) services and capabilities. The Sea Monitoring community is involved in the evaluation of the EVER-EST infrastructure. The community of potential users is wide and heterogeneous including both multi-disciplinary scientists and national/international agencies and authorities (e.g. MPAs directors, technicians from regional agencies like ARPA in Italy, the technicians working for the Ministry of the Environment) dealing with the adoption of a better way of measuring the quality of the environment. The scientific community has the main role of assessing the best criteria and indicators for defining the Good Environmental Status (GES) in their own sub regions, and implementing methods, protocols and tools for monitoring the GES descriptors. According to the Marine Strategy Framework Directive (MSFD), the environmental status of marine waters is defined by 11 descriptors, and forms a proposed set of 29 associated criteria and 56 different indicators. The objective of the Sea Monitoring VRC is to provide useful and applicable contributions to the evaluation of the descriptors: D1.Biodiversity, D2.Non-indigenous species and D6.Seafloor Integrity (http://ec.europa.eu/environment/marine/good-environmental-status/index_en.htm). The main challenges for the community members are: 1. discovery of existing data and products distributed among different infrastructures; 2. sharing methodologies about the GES evaluation and monitoring; 3. working on the same workflows and data; 4. adopting shared powerful tools for data processing (e.g. software and servers). The Sea Monitoring portal provides the VRC users with tools and services aimed at enhancing their ability to interoperate and share knowledge, experience and methods for GES assessment and monitoring, such as: •digital information services for data management, exploitation and preservation (accessibility of heterogeneous data sources including associated documentation); •e-collaboration services to communicate and share knowledge, ideas, protocols and workflows; •e-learning services to facilitate the use of common workflows for assessing GES indicators; •e-research services for workflow management, validation and verification, as well as visualization and interactive services. The current study is co-financed by the European Union's Horizon 2020 research and innovation programme under the EVER-EST project (Grant Agreement No. 674907).

Knowledge of sea ice is critical to the hunting, whaling, and cultural activities of many Indigenous communities in Northern and Western Alaska. Experienced hunters have monitored seasonal changes of the sea ice over many years, giving them a unique expertise in assessing the current state of the sea ice as well as any anomalies in seasonal sea ice conditions. The Seasonal Ice Zone Observing Network (SIZONet), in collaboration with the Exchange for Local Observations and Knowledge of the Arctic (ELOKA), has developed an online application for collecting, storing, and analyzing sea ice observations contributed by local experts from coastal Alaskan communities. Here we present the current iteration of the application, outline future plans and discuss how the development process and resulting system have improved our collective understanding of sea ice processes and changes. The SIZONet application design is based on the needs of the research scientists responsible for entering observation data into the database, the needs of local sea ice experts contributing their observations and knowledge, and the information needs of Alaska coastal communities. Entry forms provide a variety of input methods, including menus, check boxes, and free text input. Input options strive to balance flexibility in capturing concepts and details with the need for analytical consistency. Currently, research staff at the University of Alaska Fairbanks use the application to enter observations received via written or electronic communications from local sea ice experts. Observation data include current weather conditions, snow and ice quantity and quality, and wildlife sighted or taken. Future plans call for direct use of the SIZONet interface by local sea ice experts as well as students, both as contributors to the data collection and as users seeking meaning in the data. This functionality is currently available to a limited number of community members as we extend the application to support specific roles for particular users (or groups of users); this role-based access will be necessary to support a diverse user population while maintaining the integrity of the data and protecting personal information, or the location of sensitive sites, captured in the data records. Additionally, future improvements to the interface will include the ability to upload photos and videos to capture visual records of the environment. The SIZONet application was developed to provide a robust interface for working with observational data. The contributed nature of the data, however, presents a unique set of collaborative benefits and challenges as we work towards the final implementation of the application. The successful partnership supporting the observation network is a direct function of the long-term relationships established between university-based researchers and community members.

Community-based mental health services are emphasized in the World Health Organization’s Mental Health Action Plan , the World Bank’s Disease Control Priorities , and the Action Plan of the World Psychiatric Association. There is increasing evidence for effectiveness of mental health interventions delivered by non-specialists in community platforms in low- and middle-income countries (LMIC). However, the role of community components has yet to be summarized. Our objective was to map community interventions in LMIC, identify competencies for community-based providers, and highlight research gaps. Using a review-of-reviews strategy, we identified 23 reviews for the narrative synthesis. Motivations to employ community components included greater accessibility and acceptability compared to healthcare facilities, greater clinical effectiveness through ongoing contact and use of trusted local providers, family involvement, and economic benefits. Locations included homes, schools, and refugee camps, as well as technology-aided delivery. Activities included awareness raising, psychoeducation, skills training, rehabilitation, and psychological treatments. There was substantial variation in the degree to which community components were integrated with primary care services. Addressing gaps in current practice will require assuring collaboration with service users, utilizing implementation science methods, creating tools to facilitate community services and evaluate competencies of providers, and developing standardized reporting for community-based programs.

Desire to Be Underweight: Exploratory Study on a Weight Loss App Community and User Perceptions of the Impact on Disordered Eating Behaviors

Background Mobile health (mHealth) apps for weight loss (weight loss apps) can be useful diet and exercise tools for individuals in need of losing weight. Most studies view weight loss app users as these types of individuals, but not all users have the same needs. In fact, users with disordered eating behaviors who desire to be underweight are also utilizing weight loss apps; however, few studies give a sense of the prevalence of these users in weight loss app communities and their perceptions of weight loss apps in relation to disordered eating behaviors. Objective The aim of this study was to provide an analysis of users’ body mass indices (BMIs) in a weight loss app community and examples of how users with underweight BMI goals perceive the impact of the app on disordered eating behaviors. Methods We focused on two aspects of a weight loss app (DropPounds): profile data and forum posts, and we moved from a broader picture of the community to a narrower focus on users’ perceptions. We analyzed profile data to better understand the goal BMIs of all users, highlighting the prevalence of users with underweight BMI goals. Then we explored how users with a desire to be underweight discussed the weight loss app’s impact on disordered eating behaviors. Results We found three main results: (1) no user (regardless of start BMI) starts with a weight gain goal, and most users want to lose weight; (2) 6.78% (1261/18,601) of the community want to be underweight, and most identify as female; (3) users with underweight BMI goals tend to view the app as positive, especially for reducing bingeing; however, some acknowledge its role in exacerbating disordered eating behaviors. Conclusions These findings are important for our understanding of the different types of users who utilize weight loss apps, the perceptions of weight loss apps related to disordered eating, and how weight loss apps may impact users with a desire to be underweight. Whereas these users had underweight goals, they often view the app as helpful in reducing disordered eating behaviors, which led to additional questions. Therefore, future research is needed.

Objectives China is facing the unprecedented challenge of rapidly increasing rural-to-urban migration. Migrants are in a vulnerable state when they attempt to access to primary care services. This study was designed to explore rural-to-urban migrants’ experiences in primary care, comparing their quality of primary care experiences under different types of medical institutions in Guangzhou, China. Methods The study employed a cross-sectional survey of 736 rural-to-urban migrants in Guangzhou, China in 2014. A validated Chinese version of Primary Care Assessment Tool—Adult Short Version (PCAT-AS), representing 10 primary care domains was used to collect information on migrants’ quality of primary care experiences. These domains include first contact (utilization), first contact (accessibility), ongoing care, coordination (referrals), coordination (information systems), comprehensiveness (services available), comprehensiveness (services provided), family-centeredness, community orientation and culturally competent. These measures were used to assess the quality of primary care performance as reported from patients’ perspective. Analysis of covariance was conducted for comparison on PCAT scores among migrants accessing primary care in tertiary hospitals, municipal hospitals, community health centers/community health stations, and township health centers/rural health stations. Multiple linear regression models were used to explore factors associated with PCAT total scores. Results After adjustments were made, migrants accessing primary care in tertiary hospitals (25.49) reported the highest PCAT total scores, followed by municipal hospitals (25.02), community health centers/community health stations (24.24), and township health centers/rural health stations (24.18). Tertiary hospital users reported significantly better performance in first contact (utilization), first contact (accessibility), coordination (information system), comprehensiveness (service available), and cultural competence. Community health center/community health station users reported significantly better experience in the community orientation domain. Township health center/rural health station users expressed significantly better experience in the ongoing care domain. There were no statistically significant differences across settings in the ongoing care, comprehensiveness (services provided), and family-centeredness domains. Multiple linear regression models showed that factors positively associated with higher PCAT total scores also included insurance covering parts of healthcare payment (P<0.001). Conclusions This study highlights the need for improvement in primary care provided by primary care institutions for rural-to-urban migrants. Relevant policies related to medical insurance should be implemented for providing affordable healthcare services for migrants accessing primary care. PMID:26474161

Hydroinformatics is a domain of science and technology dealing with the management of information in the field of hydrology (IWA, 2011). There is the need for innovative solutions to the challenges towards open information, integration, and communication in the Internet. This presentation provides an overview of the trends and challenges in the future of hydroinformatics, and demonstrates an information system, Iowa Flood Information System (IFIS), developed within the light of these challenges. The IFIS is a web-based platform developed by the Iowa Flood Center (IFC) to provide access to flood inundation maps, real-time flood conditions, flood forecasts both short-term and seasonal, flood-related data, information and interactive visualizations for communities in Iowa. The key element of the system's architecture is the notion of community. Locations of the communities, those near streams and rivers, define basin boundaries. The IFIS provides community-centric watershed and river characteristics, weather (rainfall) conditions, and streamflow data and visualization tools. Interactive interfaces allow access to inundation maps for different stage and return period values, and flooding scenarios with contributions from multiple rivers. Real-time and historical data of water levels, gauge heights, and rainfall conditions are available in the IFIS by streaming data from automated IFC bridge sensors, USGS stream gauges, NEXRAD radars, and NWS forecasts. 2D and 3D interactive visualizations in the IFIS make the data more understandable to general public. Users are able to filter data sources for their communities and selected rivers. The data and information on IFIS is also accessible through web services and mobile applications. The IFIS is optimized for various browsers and screen sizes to provide access through multiple platforms including tablets and mobile devices. The IFIS includes a rainfall-runoff forecast model to provide a five-day flood risk estimate for more than 1000 communities in Iowa. Multiple view modes in the IFIS accommodate different user types from general public to researchers and decision makers by providing different level of tools and details. River view mode allows users to visualize data from multiple IFC bridge sensors and USGS stream gauges to follow flooding condition along a river. The IFIS will help communities make better-informed decisions on the occurrence of floods, and will alert communities in advance to help minimize damage of floods.

Detection of Anomalous Insiders in Collaborative Environments via Relational Analysis of Access Logs

Collaborative information systems (CIS) are deployed within a diverse array of environments, ranging from the Internet to intelligence agencies to healthcare. It is increasingly the case that such systems are applied to manage sensitive information, making them targets for malicious insiders. While sophisticated security mechanisms have been developed to detect insider threats in various file systems, they are neither designed to model nor to monitor collaborative environments in which users function in dynamic teams with complex behavior. In this paper, we introduce a community-based anomaly detection system (CADS), an unsupervised learning framework to detect insider threats based on information recorded in the access logs of collaborative environments. CADS is based on the observation that typical users tend to form community structures, such that users with low a nity to such communities are indicative of anomalous and potentially illicit behavior. The model consists of two primary components: relational pattern extraction and anomaly detection. For relational pattern extraction, CADS infers community structures from CIS access logs, and subsequently derives communities, which serve as the CADS pattern core. CADS then uses a formal statistical model to measure the deviation of users from the inferred communities to predict which users are anomalies. To empirically evaluate the threat detection model, we perform an analysis with six months of access logs from a real electronic health record system in a large medical center, as well as a publicly-available dataset for replication purposes. The results illustrate that CADS can distinguish simulated anomalous users in the context of real user behavior with a high degree of certainty and with significant performance gains in comparison to several competing anomaly detection models.

The involvement of service users in health care provision in general, and specifically in substance use disorder treatment, is of growing importance. This paper explores the views of patients in a therapeutic community for alcohol dependence about clinical assessment, including general aspects about the evaluation process, and the specific characteristics of four measures: two individualised and two standardised. A focus group was conducted and data were analysed using a framework synthesis approach. Service users welcomed the experience of clinical assessment, particularly when conducted by therapists. The duration of the evaluation process was seen as satisfactory and most of its contents were regarded as relevant for their population. Regarding the evaluation measures, patients diverged in their preferences for delivery formats (self-report vs. interview). Service users enjoyed the freedom given by individualised measures to discuss topics of their own choosing. However, they felt that part of the standardised questions were difficult to answer, inadequate (e.g. quantification of health status in 0-20 points) and sensitive (e.g. suicide-related issues), particularly for pre-treatment assessments. Patients perceived clinical assessment as helpful for their therapeutic journey, including the opportunity to reflect about their problems, either related or unrelated to alcohol use. Our study suggests that patients prefer to have evaluation protocols administered by therapists, and that measures should ideally be flexible in their formats to accommodate for patient preferences and needs during the evaluation.

Design science research was used for the generation, use and evaluation of a model for knowledge sharing in the user community through open educational resources (OER). The focus of interest was on the development process of a model for knowledge sharing that emphasizes the characteristics and the needs of the user community; the empowerment and democratic issues of openness; the collaboration between institutions and dialog with society; and the consideration of quality and sustainability issues. Initially, the community needs were analyzed through surveys and workshops, and the findings used, through negotiations, to formulate the development process. An open-training platform served as an infrastructure and included a repository with OER, a wiki and a discussion forum. The purpose of this article is an attempt to provide universities with a plan and template for integrated knowledge sharing that responds to societal needs.

Wearable mobile health (mHealth) technologies offer approaches for targeting physical activity (PA) in resource-limited, community-based interventions. We sought to explore user characteristics of PA tracking, wearable technology among a community-based population within a health and needs assessment. In 2014-2015, we conducted the Washington, D.C., Cardiovascular Health and Needs Assessment in predominantly African-American churches among communities with higher obesity rates and lower household incomes. Participants received a mHealth PA monitor and wirelessly uploaded PA data weekly to church data collection hubs. Participants (n = 99) were 59 ± 12 years, 79% female, and 99% African-American, with a mean body mass index of 33 ± 7 kg/m 2 . Eighty-one percent of participants uploaded PA data to the hub and were termed "PA device users." Though PA device users were more likely to report lower household incomes, no differences existed between device users and non-users for device ownership or technology fluency. Findings suggest that mHealth systems with a wearable device and data collection hub may feasibly target PA in resource-limited communities.

NSLS 2006 ACTIVITY REPORT (NATIONAL SYNCHROTRON LIGHT SOURCE ACTIVITY REPORT 2006)

MILLER, L.

This past year has seen both challenges and fantastic new opportunities for the user community at the NSLS. The fantastic new opportunities are clear and abundant. We now have a five-year strategic plan for new development and continued operation of the NSLS. The NSLS continues to be an extremely productive facility, and the UEC is delighted at how NSLS Chair Chi-Chang Kao has consulted widely within the user community to develop a five-year plan for strategic upgrades and continued operation of the facility. The NSLS-II project, led by Associate Lab Director Steve Dierker, has done very well in its Departmentmore » of Energy (DOE) reviews and will hopefully soon receive Critical Decision-1 (CD-1) approval, which in DOE lingo gives a go-ahead to launch the detailed design of the facility. We also held the first joint user meeting between the NSLS and Brookhaven's Center for Functional Nanomaterials (CFN), for which the building is near completion. The joint user meeting is an important step toward the close collaboration of the two facilities. The CFN, led by Emilio Mendez, promises to provide capabilities and research foci that are complementary to those at the NSLS. Together, all of these developments give a clear path to an exciting future of synchrotron radiation research at Brookhaven! However, with opportunities come challenges! One of the largest of these faced in the past year involved congressional support for scientific research in general, and DOE user facilities in particular. As you likely know, Congress did not complete its usual budget process in 2006, with the exceptions of the departments of Defense and Homeland Security. This left science funding at the budget levels enacted in late 2005 for FY2006, and unfortunately, FY2006 was not a particularly memorable vintage for science support. The good news is that you, the user community, have spoken up with unprecedented vigor about this, and Congress appears to be listening. As we look at the FY2007 budget and the years to follow, we need to continue to educate our elected representatives about the benefits that are provided to our society and our economy by scientific investigation including research done at DOE user facilities like the NSLS. We face another interesting challenge as the NSLS-II project progresses: the formation of scientific research teams associated with particular beamlines at the new facility. In early 2007, the final draft of the conceptual design report will be available, which will describe the projected capabilities of NSLS-II, and we can expect a workshop in mid-2007 to launch the process leading to letters of intent for beamlines. This process will include lots of discussion about access modes, as we seek ways to allow scientific and technical innovators from the user community to play significant roles at NSLS-II.« less

Mobile phone text messaging has been shown to improve adherence to antiretroviral therapy and to improve communication between patients and health care workers. It is unclear which strategies are most appropriate for scaling up text messaging programmes. We sought to investigate acceptability and readiness for ownership (community members designing, sending and receiving text messages) of a text message programme among a community of clients living with human immunodeficiency virus (HIV) in Yaoundé, Cameroon and to develop a framework for implementation. We used the mixed-methods sequential exploratory design. In the qualitative strand we conducted 7 focus group discussions (57 participants) to elicit themes related to acceptability and readiness. In the quantitative strand we explored the generalizability of these themes in a survey of 420 clients. Qualitative and quantitative data were merged to generate meta-inferences. Both qualitative and quantitative strands showed high levels of acceptability and readiness despite low rates of participation in other community-led projects. In the qualitative strand, compared to the quantitative strand, more potential service users were willing to pay for a text messaging service, preferred participation of health personnel in managing the project and preferred that the project be based in the hospital rather than in the community. Some of the limitations identified to implementing a community-owned project were lack of management skills in the community, financial, technical and literacy challenges. Participants who were willing to pay were more likely to find the project acceptable and expressed positive feelings about community readiness to own a text messaging project. Community ownership of a text messaging programme is acceptable to the community of clients at the Yaoundé Central Hospital. Our framework for implementation includes components for community members who take on roles as services users (demonstrating clear benefits, allowing a trial period and ensuring high levels of confidentiality) or service providers (training in project management and securing sustainable funding). Such a project can be evaluated using participation rate, clinical outcomes, satisfaction with the service, cost and feedback from users.

In most developed nations, ageing migrants represent a growing proportion of the older population. Policies that emphasise care in the community depend on older migrants having access to formal services along with informal support, yet little is known about how older migrants experience community-based formal services. By examining the views of both Greek elders in Australia and those of formal service providers, this research fills an important gap in the literature around access to and acceptability of formal community-based services for older migrants. A research team including two Greek background researchers used existing social groups and a snowball sampling method to conduct face-to-face interviews and focus groups with seventy older Greeks in Adelaide, Australia. In addition, 22 community-based service providers were interviewed over the telephone. Results from users and providers showed that while many older Greeks experience service access issues, they also relied heavily on family for support and assistance at home. Reliance on family was both in preference to formal services or where formal services were used, to locate, negotiate and monitor such services. Common barriers identified by both groups included cost, transport and availability, but additional challenges were posed by language, literacy and cultural attitudes. Demographic changes including greater employment mobility and female workforce participation among adult children will have implications for both formal and informal care providers. Formal service providers need to ensure that services are promoted and delivered to take account of the important role of family in informal support while also addressing the access challenges posed by language and literacy. Research conducted by researchers from the same cultural background in the respondent's native language can further advance knowledge in this area. © 2012 Blackwell Publishing Ltd.

Background While a number of studies have looked at life on service users' experiences of life on psychiatric wards, no research exists that have approached these experiences from the user perspective since the introduction of community care. Methods This user-led study uses a participatory approach to develop an understanding of the processes and themes which define the user experience of hospitalisation. Nineteen service users who had all had inpatient stays in psychiatric hospitals in London were interviewed in the community. Results Relationships formed the core of service users' experiences. Three further codes, treatment, freedom and environment defined the role of hospital and its physical aspects. Themes of communication, safety, trust, coercion, and cultural competency contributed to the concept of relationships. Conclusion Relationships with an individual which comprised effective communication, cultural sensitivity, and the absence of coercion resulted in that person being attributed with a sense of trust. This resulted in the patient experiencing the hospital as a place of safety in terms of risk from other patients and staff. Barriers to positive relationships included ineffective and negative communication, a lack of trust, a lack of safety in terms of staff as ineffective in preventing violence, and as perpetrators themselves, and the use of coercion by staff. This unique perspective both acts as a source of triangulation with previous studies and highlights the importance of the therapeutic relationship in providing a safe and therapeutic milieu for the treatment of people with acute mental health problems.

Groups and individuals that seek to negatively influence public opinion about the safety and value of vaccination are active in online and social media and may influence decision making within some communities. We sought to measure whether exposure to negative opinions about human papillomavirus (HPV) vaccines in Twitter communities is associated with the subsequent expression of negative opinions by explicitly measuring potential information exposure over the social structure of Twitter communities. We hypothesized that prior exposure to opinions rejecting the safety or value of HPV vaccines would be associated with an increased risk of posting similar opinions and tested this hypothesis by analyzing temporal sequences of messages posted on Twitter (tweets). The study design was a retrospective analysis of tweets related to HPV vaccines and the social connections between users. Between October 2013 and April 2014, we collected 83,551 English-language tweets that included terms related to HPV vaccines and the 957,865 social connections among 30,621 users posting or reposting the tweets. Tweets were classified as expressing negative or neutral/positive opinions using a machine learning classifier previously trained on a manually labeled sample. During the 6-month period, 25.13% (20,994/83,551) of tweets were classified as negative; among the 30,621 users that tweeted about HPV vaccines, 9046 (29.54%) were exposed to a majority of negative tweets. The likelihood of a user posting a negative tweet after exposure to a majority of negative opinions was 37.78% (2780/7361) compared to 10.92% (1234/11,296) for users who were exposed to a majority of positive and neutral tweets corresponding to a relative risk of 3.46 (95% CI 3.25-3.67, P<.001). The heterogeneous community structure on Twitter appears to skew the information to which users are exposed in relation to HPV vaccines. We found that among users that tweeted about HPV vaccines, those who were more often exposed to negative opinions were more likely to subsequently post negative opinions. Although this research may be useful for identifying individuals and groups currently at risk of disproportionate exposure to misinformation about HPV vaccines, there is a clear need for studies capable of determining the factors that affect the formation and adoption of beliefs about public health interventions.

2017-01-01

Background Recent research has shown that of the 72% of American Internet users who have looked for health information online, 22% have searched for help to lose or control weight. This demand for information has given rise to many online weight management communities, where users support one another throughout their weight loss process. Whether and how user engagement in online communities relates to weight change is not totally understood. Objective We investigated the activity behavior and analyze the semantic content of the messages of active users in LoseIt (r/loseit), a weight management community of the online social network Reddit. We then explored whether these features are associated with weight loss in this online social network. Methods A data collection tool was used to collect English posts, comments, and other public metadata of active users (ie, users with at least one post or comment) on LoseIt from August 2010 to November 2014. Analyses of frequency and intensity of user interaction in the community were performed together with a semantic analysis of the messages, done by a latent Dirichlet allocation method. The association between weight loss and online user activity patterns, the semantics of the messages, and real-world variables was found by a linear regression model using 30-day weight change as the dependent variable. Results We collected posts and comments of 107,886 unique users. Among these, 101,003 (93.62%) wrote at least one comment and 38,981 (36.13%) wrote at least one post. Median percentage of days online was 3.81 (IQR 9.51). The 10 most-discussed semantic topics on posts were related to healthy food, clothing, calorie counting, workouts, looks, habits, support, and unhealthy food. In the subset of 754 users who had gender, age, and 30-day weight change data available, women were predominant and 92.9% (701/754) lost weight. Female gender, body mass index (BMI) at baseline, high levels of online activity, the number of upvotes received per post, and topics discussed within the community were independently associated with weight change. Conclusions Our findings suggest that among active users of a weight management community, self-declaration of higher BMI levels (which may represent greater dissatisfaction with excess weight), high online activity, and engagement in discussions that might provide social support are associated with greater weight loss. These findings have the potential to aid health professionals to assist patients in online interventions by focusing efforts on increasing engagement and/or starting discussions on topics of higher impact on weight change.

Community-engaged health informatics (CEHI) applies information technology and participatory approaches to improve the health of communities. Our objective was to translate the concept of CEHI into a usable and replicable informatics platform that will facilitate community-engaged practice and research. The setting is a diverse urban neighborhood in New York City. The methods included community asset mapping, stakeholder interviews, logic modeling, analysis of affordances in open-source tools, elicitation of use cases and requirements, and a survey of early adopters. Based on synthesis of data collected, GetHealthyHeigths.org (GHH) was developed using open-source LAMP stack and Drupal content management software. Drupal's organic groups module was used for novel participatory functionality, along with detailed user roles and permissions. Future work includes evaluation of GHH and its impact on agency and service networks. We plan to expand GHH with additional functionality to further support CEHI by combining informatics solutions with community engagement to improve health.

Illicit drug use (IDU) is an important risk factor for hepatitis A, but implementing vaccination programs among drug users is difficult. During January 2001-July 2002, 403 hepatitis A cases were reported in Polk County, Florida; 48% were drug users and of these, 80% were recently in jail. To assess the county jail as a potential vaccination venue, we interviewed 280 inmates and conducted a serologic survey during July--August 2002. Of these, 227 (81%) reported a past IDU history. Previous HAV infection was found in 33%. In communities with illicit drug users at risk for hepatitis A and who are frequently jailed, vaccination programs in jails could be an important component of a community-based strategy to control hepatitis A outbreaks among illicit drug users.

Applying Agile Methods to the Development of a Community-Based Sea Ice Observations Database

Local and traditional knowledge and community-based monitoring programs are increasingly being recognized as an important part of establishing an Arctic observing network, and understanding Arctic environmental change. The Seasonal Ice Zone Observing Network (SIZONet, http://www.sizonet.org) project has implemented an integrated program for observing seasonal ice in Alaska. Observation and analysis by local sea ice experts helps track seasonal and inter-annual variability of the ice cover and its use by coastal communities. The ELOKA project (http://eloka-arctic.org) is collaborating with SIZONet on the development of a community accessible, Web-based application for collecting and distributing local observations. The SIZONet project is dealing with complicated qualitative and quantitative data collected from a growing number of observers in different communities while concurrently working to design a system that will serve a wide range of different end users including Arctic residents, scientists, educators, and other stakeholders with a need for sea ice information. The benefits of linking and integrating knowledge from communities and university-based researchers are clear, however, development of an information system in this multidisciplinary, multi-participant context is challenging. Participants are geographically distributed, have different levels of technical expertise, and have varying goals for how the system will be used. As previously reported (Pulsifer et al. 2010), new technologies have been used to deal with some of the challenges presented in this complex development context. In this paper, we report on the challenges and innovations related to working as a multi-disciplinary software development team. Specifically, we discuss how Agile software development methods have been used in defining and refining user needs, developing prototypes, and releasing a production level application. We provide an overview of the production application that includes discussion of a hybrid architecture that combines a traditional relational database, schema-less database, advanced free text search, and the preliminary framework for Semantic Web support. The current version of the SIZONet web application is discussed in relation to the high-value features defined as part of the Agile approach. Preliminary feedback indicates a system that meets the needs of multiple user groups.

The main objectives of the system are to store space geodesy and geodynamics related data products in a central data bank, to maintain infom1ation about the archival of these data, and to disseminate these data and information in a timely mam1er to a global scientific research community. The archive consists of GNSS, laser ranging, VLBI, and OORIS data sets and products derived from these data. The coors is one of NASA's Earth Observing System Oata and Infom1ation System (EOSorS) distributed data centers; EOSOIS data centers serve a diverse user community and are tasked to provide facilities to search and access science data and products. The coors data system and its archive have become increasingly important to many national and international science communities, in pal1icular several of the operational services within the International Association of Geodesy (lAG) and its project the Global Geodetic Observing System (GGOS), including the International OORIS Service (IDS), the International GNSS Service (IGS), the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS), and the International Earth Rotation Service (IERS). The coors has recently expanded its archive to supp011 the IGS Multi-GNSS Experiment (MGEX). The archive now contains daily and hourly 3D-second and subhourly I-second data from an additional 35+ stations in RINEX V3 fOm1at. The coors will soon install an Ntrip broadcast relay to support the activities of the IGS Real-Time Pilot Project (RTPP) and the future Real-Time IGS Service. The coors has also developed a new web-based application to aid users in data discovery, both within the current community and beyond. To enable this data discovery application, the CDDIS is currently implementing modifications to the metadata extracted from incoming data and product files pushed to its archive. This poster will include background information about the system and its user communities, archive contents and updates, enhancements for data discovery, new system architecture, and future plans.

Background This study investigates whether a recovery management intervention (RMI) can improve the utilization of community drug treatment and wraparound services among heroin users in China and subsequently lead to positive recovery outcomes. Methods Secondary analysis was conducted drawing data from a randomized controlled trial; 100 heroin users with no severe mental health problems were recruited in two Shanghai districts (Hongkou and Yangpu) upon their release from compulsory rehabilitation facilities. A latent variable modeling approach was utilized to test whether the RMI influences heroin users' perceived motivation and readiness for treatment, enhances treatment and wraparound service participation, and, in turn, predicts better recovery outcomes. Results Enrollment in drug treatment and other social service utilization increased significantly as a result of RMI rather than an individual drug user's motivation and readiness for treatment. Increased service utilization thus led to more positive individual recovery outcomes. In addition to this mediation effect through service utilization, the RMI also improved participants' community recovery directly. Conclusions Findings suggest that better drug treatment enrollment, community service utilization and recovery outcomes can be potentially achieved among heroin users in China with carefully designed case management interventions.

Many cyberinfrastructure systems in the hydrologic and related domains emerged in the past decade with more being developed to address various data management and modeling needs. Although clearly beneficial to the broad user community, it is a challenging task to build interoperability across these systems due to various obstacles including technological, organizational, semantic, and social issues. This work presents our experience in developing interoperability between two hydrologic cyberinfrastructure systems - SWATShare and HydroShare. HydroShare is a large-scale online system aiming at enabling the hydrologic user community to share their data, models, and analysis online for solving complex hydrologic research questions. On the other side, SWATShare is a focused effort to allow SWAT (Soil and Water Assessment Tool) modelers share, execute and analyze SWAT models using high performance computing resources. Making these two systems interoperable required common sign-in through OAuth, sharing of models through common metadata standards and use of standard web-services for implementing key import/export functionalities. As a result, users from either community can leverage the resources and services across these systems without having to manually importing, exporting, or processing their models. Overall, this use case is an example that can serve as a model for the interoperability among other systems as no one system can provide all the functionality needed to address large interdisciplinary problems.

While Web-based interventions have proliferated recently, information in the literature is often lacking about how the intervention was developed. In response to that gap, this is a report of the development of a Web-based self-management intervention for intermittent urinary catheter users and pretesting with four adults with spinal cord injury living in the community. Two Web sites were created, one for recruitment and the other for the intervention itself. The intervention involved developing new Web-based technology, including an interactive urinary diary (with fluid intake/urine output and a journal), extensive catheter products information, three intervention nurse phone call consultations, and user-community discussion forums. Study participants completed an online survey and were interviewed twice about the enrollment process and their perceptions of their involvement in the intervention. Suggestions from the pretesting participants were used to revise the Web site applications prior to the next stage of research (a feasibility study). Numerous recommendations and comments were received related to content, interactivity of components, and usability. This article provides a description of how the Web sites were developed (including the technology and software programs used), issues encountered and what was done to address them, and how the Web-based intervention was modified for improvements.

The copper intrauterine device (IUD) is a safe, long-acting, and effective method of contraception that is under-utilized in many countries, including Malawi. A unique cohort of women who had enrolled in a trial of postpartum IUD use one year earlier gave insights into reasons for using, discontinuing, or not using the IUD. We conducted in-depth interviews with 18 women one year after they participated in a pilot study of a randomized controlled trial of postpartum IUD insertion, and 10 of their male partners. Women and their partners expressed a strong desire for family planning, and perceived numerous benefits of the IUD. However, fear of the IUD was common among successful users and non-users alike. This fear arose from rumours from friends and neighbors who were non-users. How women and their partners responded to this fear affected IUD adoption and continuation. Key themes included (1) Trust in information received from health care providers versus rumours from community members; (2) Partner involvement in IUD decision-making; and (3) Experience with side effects from short-term hormonal contraceptive methods. Broad community education about the IUD's benefits and safety, and proactive counseling to address couples' specific fears, may be needed to increase uptake of the method.

The use of web-based portals, while increasing in popularity in the fields of medicine and research, are rarely reported on in community-based rehabilitation programs. A program within the Pennsylvania Office of Vocational Rehabilitation’s Hiram G. Andrews Center, the Cognitive Skills Enhancement Program (CSEP), sought to enhance organization of program and participant information and communication between part- and full-time employees, supervisors and consultants. A telerehabilitation system was developed consisting of (1) a web-based portal to support a variety of clinical activities, and (2) the Versatile Integrated System for Telerehabilitation (VISYTER) video-conferencing system to support the collaboration and delivery of rehabilitation services remotely. This descriptive evaluation examines the usability of the telerehabilitation system incorporating both the portal and VISYTER. Telerehabilitation system users include CSEP staff members from three geographical locations and employed by two institutions. The IBM After-Scenario Questionnaire (ASQ) and Post-Study System Usability Questionnaire (PSSUQ), the Telehealth Usability Questionnaire (TUQ), and two demographic surveys were administered to gather both objective and subjective information. Results showed generally high levels of usability. Users commented that the telerehabilitation system improved communication, increased access to information, improved speed of completing tasks, and had an appealing interface. Areas where users would like to see improvements, including ease of accessing/editing documents and searching for information, are discussed. PMID:25945193

Quality control (QC) is crucial for any scientific method producing data. Applying adequate QC introduces new challenges in the genomics field where large amounts of data are produced with complex technologies. For DNA microarrays, specific algorithms for QC and pre-processing including normalization have been developed by the scientific community, especially for expression chips of the Affymetrix platform. Many of these have been implemented in the statistical scripting language R and are available from the Bioconductor repository. However, application is hampered by lack of integrative tools that can be used by users of any experience level. To fill this gap, we developed a freely available tool for QC and pre-processing of Affymetrix gene expression results, extending, integrating and harmonizing functionality of Bioconductor packages. The tool can be easily accessed through a wizard-like web portal at http://www.arrayanalysis.org or downloaded for local use in R. The portal provides extensive documentation, including user guides, interpretation help with real output illustrations and detailed technical documentation. It assists newcomers to the field in performing state-of-the-art QC and pre-processing while offering data analysts an integral open-source package. Providing the scientific community with this easily accessible tool will allow improving data quality and reuse and adoption of standards. PMID:23620278

Millar, Samantha L; Chambers, Mary; Giles, Melanie

2016-04-01

The concept of service user involvement is an evolving concept in the mental health-care literature. This study sought to explore and analyse the concept of service user involvement as used in within the field of mental health care. An evolutionary concept analysis was conducted using a literature-based sample extracted from an electronic database search. One hundred and thirty-four papers met the inclusion criteria and were analysed to discover key attributes, antecedents and consequences of service user involvement and to produce a definition of the concept. Five key attributes of service user involvement within the context of mental health care were identified: a person-centred approach, informed decision making, advocacy, obtaining service user views and feedback and working in partnership. Clarity of the attributes and definition of the concept of service user involvement aims to promote understanding of the concept among key stakeholders including mental health professionals, service users and community and voluntary organizations. The findings of the research have utility in the areas of theory and policy development, research on service user involvement in mental health care and service user involvement in mental health practice. Directions for further research regarding the concept are identified. © 2015 John Wiley & Sons Ltd.

SpecDB: The AAVSO’s Public Repository for Spectra of Variable Stars

NASA Astrophysics Data System (ADS)

Kafka, Stella; Weaver, John; Silvis, George; Beck, Sara

2018-01-01

SpecDB is the American Association of Variable Star Observers (AAVSO) spectral database. Accessible to any astronomer with the capability to perform spectroscopy, SpecDB provides an unprecedented scientific opportunity for amateur and professional astronomers around the globe. Backed by the Variable Star Index, one of the most utilized variable star catalogs, SpecDB is expected to become one of the world leading databases of its kind. Once verified by a team of expert spectroscopists, an observer can upload spectra of variable stars target easily and efficiently. Uploaded spectra can then be searched for, previewed, and downloaded for inclusion in publications. Close community development and involvement will ensure a user-friendly and versatile database, compatible with the needs of 21st century astrophysics. Observations of 1D spectra are submitted as FITS files. All spectra are required to be preprocessed for wavelength calibration and dark subtraction; Bias and flat are strongly recommended. First time observers are required to submit a spectrum of a standard (non-variable) star to be checked for errors in technique or equipment. Regardless of user validation, FITS headers must include several value cards detailing the observation, as well as information regarding the observer, equipment, and observing site in accordance with existing AAVSO records. This enforces consistency and provides necessary details for follow up analysis. Requirements are provided to users in a comprehensive guidebook and accompanying technical manual. Upon submission, FITS headers are automatically checked for errors and any anomalies are immediately fed back to the user. Successful candidates can then submit at will, including multiple simultaneous submissions. All published observations can be searched and interactively previewed. Community involvement will be enhanced by an associated forum where users can discuss observation techniques and suggest improvements to the database.

This paper describes the science operations model for the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. ASKAP is a radio interferometer currently being commissioned in Western Australia. It will be operated by a dedicated team of observatory staff with the support of telescope monitoring, control and scheduling software. These tools, as well as the proposal tools and data archive will enable the telescope to operate with little direct input from the astronomy user. The paper also discusses how close engagement with the telescope user community has been maintained throughout the ASKAP construction and commissioning phase, leading to positive outcomes including early input into the design of telescope systems and a vibrant early science program.

Stigma and discrimination against people with mental illness remain barriers to help seeking and full recovery for people in need of mental health services. Yet there is scarce research investigating the experiences of psychiatric stigma on mental health service users in low- and middle-income countries (LMICs). The aim of this study was therefore to explore the experiences of psychiatric stigma by service users in order to inform interventions to reduce such stigma and discrimination in one LMIC, namely South Africa. Participants comprised a total of 77 adults aged above 18 years, made up of service providers including professional nurses (10), lay counsellors (20), auxiliary social workers (2); and service users (45). Psychiatric stigma was found to be perpetuated by family members, friends, employers, community members and health care providers. Causes of psychiatric stigma identified included misconceptions about mental illness often leading to delays in help-seeking. Experiencing psychiatric stigma was reported to worsen the health of service users and impede their capacity to lead and recover a normal life. Media campaigns and interventions to reduce stigma should be designed to address specific stigmatizing behaviours among specific segments of the population. Counselling of families, caregivers and service users should include how to deal with experienced and internalized stigma.

2014-05-01

To explore the individual experience of being a scooter user and the ways in which scooters impact the individual's community and social engagement, daily activities and enhances mobility. A qualitative, constructive framework utilising purposive sampling and a semi structured interview was used with 14 individuals. Questions were categorised according to the International Classification of Functioning, Disability and Health framework into the three areas of activities, participation and environmental factors. The three main themes identified through the research were knowledge, engagement and environments. Knowledge included a lack of concise information, and adequate trialling and training prior to purchase. Engagement consisted of participation and interaction demonstrating scooter use resulted in increased participation, role maintenance, choice, freedom and social interaction. Environments highlighted discrimination from the wider population and building design and barriers. The research demonstrated a strong positive impact on individual's engagement from using a scooter, while highlighting a lack of adequate knowledge about scooters, batteries, skill ability and design along with environmental challenges of discriminatory attitudes and physical barriers. The research indicates the need for pre-purchase assessments and trials along with improvements in community attitudes and environments. Development of a pre-purchase assessment including specific core skills for scooter use is of great importance to minimise accidents and death as a consequence of scooter driving. Education and training of prescribers and suppliers of scooters is important to match needs and skills to enable a better fit of scooter to user. Incorporation of adjustability of features within the standard design of scooters, including type of driving controls, seat height, and adjustment of distance to controls, will enable greater fit of scooter to the user s needs.

Case reports and hospital-based case-control studies suggest that cannabis use may increase the risk of stroke. We examined the risk of non-fatal stroke or transient ischemic attack (TIA) among cannabis users in the general community. A general population survey of Australians aged 20-24 years (n=2,383), 40-44 years (n=2,525) and 60-64 years (n=2,547) was used to determine the odds of lifetime stroke or TIA among participants who had smoked cannabis in the past year while adjusting for other stroke risk factors. There were 153 stroke/TIA cases (2.1%). After adjusting for age cohort, past year cannabis users (n=1,043) had 3.3 times the rate of stroke/TIA (95% CI 1.8-6.3, p<0.001). The incidence rate ratio (IRR) reduced to 2.3 after adjustment for covariates related to stroke, including tobacco smoking (95% CI 1.1-4.5). Elevated stroke/TIA was specific to participants who used cannabis weekly or more often (IRR 4.7, 95% CI 2.1-10.7) with no elevation among participants who used cannabis less often. Heavy cannabis users in the general community have a higher rate of non-fatal stroke or transient ischemic attack than non-cannabis users. © 2015 Public Health Association of Australia.

Identifying and Tracing User Needs

To, C.; Tauer, E.

2017-12-01

Providing adequate tools to the user community hinges on reaching the specific goals and needs behind the intended application of the tool. While the approach of leveraging user-supplied inputs and use cases to identify those goals is not new, there frequently remains the challenge of tracing those use cases through to implementation in an efficient and manageable fashion. Processes can become overcomplicated very quickly, and additionally, explicitly mapping progress towards the achievement of the user demands can become overwhelming when hundreds of use-cases are at play. This presentation will discuss a demonstrated use-case approach that has achieved an initial success with a tool re-design and deployment, the means to apply use cases in the generation of a roadmap for future releases over time, and the ability to include and adjust to new user requirements and suggestions with minimal disruption to the traceability. It is hoped that the findings and lessons learned will help make use case employment easier for others seeking to create user-targeted capabilities.

2002-12-01

DLESE is a community-owned and governed digital library offering easy access to high quality electronic resources about the Earth system at all educational levels. Currently in its third year of development and operation, DLESE resources are designed to support systemic educational reform, and include web-based teaching resources, tools, and services for the inclusion of data in classroom activities, as well as a "virtual community center" that supports community goals and growth. "Community-owned" and "community-governed" embody the singularity of DLESE through its unique participatory approach to both library building and governance. DLESE is guided by policy development vested in the DLESE Steering Committee, and informed by Standing Committees centered on Collections, Services, Technology, and Users, and community working groups covering a wide variety of interest areas. This presentation highlights both current and projected status of the library and opportunities for community engagement. It is specifically structured to engage community members in the design of the next version of the library release. The current Version 1.0 of the library consists of a web-accessible graphical user interface connected to a database of catalogued educational resources (approximately 3000); a metadata framework enabling resource characterization; a cataloging tool allowing community cataloging and indexing of materials; a search and discovery system allowing browsing based on topic, grade level, and resource type, and permitting keyword and controlled vocabulary-based searches; and a portal website supporting library use, community action, and DLESE partnerships. Future stages of library development will focus on enhanced community collaborative support; development of controlled vocabularies; collections building and community review systems; resource discovery integrating the National Science Education Standards and geography standards; Earth system science vocabulary; georeferenced discovery; and ultimately, AAAS Benchmarks. DLESE is being designed from the outset to support resource discovery across a diverse, federated network of holdings and collections, including the Alexandria Digital Library Earth Prototype (ADL/ADEPT), NASA education collections, the DLESE reviewed collection, and other community-held resources that have been cataloged and indexed as part of the overall DLESE collections.

Healthcare user fees present an important barrier for accessing services for the poorest (indigents) in Burkina Faso and selective removal of fees has been incorporated in national healthcare planning. However, establishing fair, effective and sustainable mechanisms for the removal of user fees presents important challenges. A participatory action-research project was conducted in Ouargaye, Burkina Faso, to test mechanisms for identifying those who are indigents, and funding and implementing user fee removal. In this paper, we explore stakeholder perceptions of ethical considerations relating to participation and partnership arising in the action-research. We conducted 39 in-depth interviews to examine ethical issues associated with the action-research. Respondents included 14 individuals identified as indigent through the community selection process, seven members of village selection committees, six local healthcare professionals, five members of the management committees of local health clinics, five members of the research team, and four regional or national policy-makers. Using constant comparative techniques, we carried out an inductive thematic analysis of the collected data. The Ouargaye project involved a participatory model, included both implementation and research components, and focused on a vulnerable group within small, rural communities. Stakeholder perceptions and experiences relating to the participatory approach and reliance on multiple partnerships in the project were associated with a range of ethical considerations related to 1) seeking common ground through communication and collaboration, 2) community participation and risk of stigmatization, 3) impacts of local funding of the user fee removal, 4) efforts to promote fairness in the selection of the indigents, and 5) power relations and the development of partnerships. This investigation of the Ouargaye project serves to illuminate the distinctive ethical terrain of a participatory public health action-research project. In carrying out such projects, careful attention and effort is needed to establish and maintain respectful relationships amongst those involved, acknowledge and address differences of power and position, and evaluate burdens and risks for individuals and groups.

2018-04-05

The Internet provides an accessible context for online gambling and gambling-related online communities, such as discussion forums for gamblers. These communities may be particularly attractive to young gamblers who are active Internet users. The aim of this study was to examine the use of gambling-related online communities and their relevance to excessive gambling among 15-25-year-old Finnish Internet users (N = 1200). Excessive gambling was assessed by using the South Oaks Gambling Screen. Respondents were asked in a survey about their use of various kinds of gambling-related online communities, and sociodemographic and behavioral factors were adjusted. The results of the study revealed that over half (54.33%) of respondents who had visited gambling-related online communities were either at-risk gamblers or probable pathological gamblers. Discussion in these communities was mainly based on sharing gambling tips and experiences, and very few respondents said that they related to gambling problems and recovery. In three different regression models, visiting gambling-related online communities was a significant predictor for excessive gambling (with 95% confidence level) even after adjusting confounding factors. The association of visiting such sites was even stronger among probable pathological gamblers than among at-risk gamblers. Health professionals working with young people should be aware of the role of online communities in terms of development and persistence of excessive gambling. Monitoring the use of online gambling communities as well as utilizing recovery-oriented support both offline and online would be important in preventing further problems. Gambling platforms should also include warnings about excessive gambling and provide links to helpful sources.

The amount of hydrological data available from NASA remote sensing and modeling systems is vast and ever-increasing;but, one challenge persists:increasing the usefulness of these data for, and thus their use by, end user communities. The Hydrology Data and Information Services Center (HDISC), part of the Goddard Earth Sciences DISC, has continually worked to better understand the hydrological data needs of different end users, to thus better able to bridge the gap between NASA data and end user communities. One effective strategy is integrating the data in to end user community tools and environments. There is an ongoing collaborative effort between NASA HDISC, NASA Hydrological Sciences Branch, and CUAHSI to integrate NASA gridded hydrology data in to the CUAHSI Hydrologic Information System (HIS).

Objectives The Global Model of Public Mental Health is "global" not only in the sense of having an international perspective, but in regarding service users as actors at all levels of public mental health exerting collective and organized influence on the social determinants of health, in addition to being recipients of care. Having access to appropriate health and mental health care when needed is a fundamental human right. Having a say over the manner in which care is provided, including partnership in decision making in care planning and ongoing care, has gained increasing support among recipients and providers of care. Over the past few decades in the Canadian province of Quebec, patient participation and partnership in decision-making has been promoted through successive Mental Health Action Plans (MHAP) and other policies. In these documents, participation and partnership are associated with the exercise of citizenship and the promotion of service users' rights, including the rights to participate in one's own care. In this article, using the case example of a citizenship-oriented intervention, namely the Projet citoyen, we discuss the results to a new measure of citizenship, which was developed from a service users' perspective.Methods Employing a mixed methods approach, two types of data were collected from users of mental health care. Quantitative data were generated from administration of a 23-item measure of citizenship with service users in the province of Quebec (N=802), and qualitative data were collected from four focus groups with another sample of 18 service users. They were presented with results from the administration of the measure, and asked to comment on them in regard to their own experience of citizenship.Results Among the five dimensions of the measure of citizenship, participants scored lowest on the 'involvement in the community' dimension, and higher on the other dimensions of 'basic needs,' 'respect by others,' 'self-determination,' and 'access to services.' In focus groups, participants said that there is still prejudice in society and discrimination towards people with mental illnesses that limit their right to participate in public debate and mental health programming. Public health interventions at this level may help to change attitudes and social representations, as they are inclusive of persons with lived experience of mental illness. Public discussion of citizenship issues in relation to mental health also represent an opportunity for participants to confront existing problems, as a first step toward collective action.Conclusion People's lived experience of regaining a sense of citizenship and of belonging to their local neighborhoods and communities, including the scientific micro-community, can help to foster an evolution of public health from disease management to health promotion and community inclusion. More research is needed to compare the sense of citizenship to the rest of the population and to see if specific interventions can have an enduring impact (e.g.: pre/post design).

In order to provide the land cover user community a summary of the similarity and differences between the 2011 National Land Cover Dataset (NLCD) and the Landscape Fire and Resource Management Planning Tools Program Existing Vegetation 2010 Data (LANDFIRE EVT), the two datasets were compared at a national (conterminous U.S.) and regional (Eastern, Midwestern, and Western) extents (Figure 1). The comparisons were done by generalizing the LANDFIRE data to be consistent with mapped land cover classes in the NLCD (i.e., crosswalked). Summaries of the comparisons were based on areal extent including 1) the total extent of each land cover class, and 2) land cover classes in corresponding 900-m2 areas. The results from the comparisons provide the user community information regarding the utility of both datasets relative to their intended uses.

Near Real Time Operational Satellite Ocean Color Products From NOAA OSPO CoastWatch Okeanos System:: Status and Challenges

NASA Astrophysics Data System (ADS)

Banghua Yan, B.

2016-02-01

Near real-time (NRT) ocean color (OC) satellite operation products are generated and distributed in NOAA Okeanos Operational Product System, by using the CWAPS including the Multi-Sensor Level (MSL) 12 and the chlorophyll-a frontal algorithms. Current OC operational products include daily chlorophyll concentration (anomaly), water turbidity, remote sensing reflectance and chlorophyll frontal products from Moderate-resolution Imaging Spectroradiometer (MODIS)/Aqua. The products have been widely applied to USA local and state ecosystem research, ecosystem observations, and fisheries managements for coastal and regional forecasting of ocean water quality, phytoplankton concentrations, and primary production. Users of the products have the National Ocean Service, National Marine Fisheries Service, National Weather Service, and Oceanic and Atmospheric Research. Recently, the OC products are being extended to S-NPP VIIRS to provide global NRT ocean color products to user community suh as National Weatrher Service for application for Global Data Assimilation System and Real-Time Ocean Forecast System. However, there remain some challenges in application of the products due to certain product quality and coverage issues. Recent efforts were made to provide a comprehensive web-based Quality Assurance (QA) tool for monitoring OC products quality in near real time mode, referring to http://www.ospo.noaa.gov/Products/ocean/color_new/color.htm. The new QA monitoring tool includes but not limited to the following advanced features applicable for MODIS/Aqua and NPP/VIIRS OC products: 1) Monitoring product quality in NRT mode; 2) Monitoring the availability and quality of OC products with time; 3) Detecting anomalous OC products due to low valid pixels and other quality issues. As an example, potential application and challenges of the ocean color products to oceanic oil spill detection are investigated. It is thus expected that the Okeanos ocean color operational system in combination with the new QA monitoring tool will more efficiently ensure availability and quality of satellite operational OC products from Okeanos system to the user community. The QA tool also will provide much useful information of OC products quality and statistics to the OC user community.

Today s HPC centers user environments can be very complex. Centers often contain multiple large complicated computational systems each with their own user environment. Changes to a system s environment can be very impactful; however, a center s user environment is, in one-way or another, frequently changing. Because of this, it is vital for centers to notify users of change. For users, untracked changes can be costly, resulting in unnecessary debug time as well as wasting valuable compute allocations and research time. Communicating frequent change to diverse user communities is a common and ongoing task for HPC centers. This papermore » will cover the OLCF s current processes and methods used to communicate change to users of the center s large Cray systems and supporting resources. The paper will share lessons learned and goals as well as practices, tools, and methods used to continually improve and reach members of the OLCF user community.« less

Interventions for tobacco cessation in the dental setting

PubMed Central

Carr, Alan B; Ebbert, Jon

2014-01-01

Background Tobacco use has significant adverse effects on oral health. Oral health professionals in the dental office or community setting have a unique opportunity to increase tobacco abstinence rates among tobacco users. Objectives This review assesses the effectiveness of interventions for tobacco cessation delivered by oral health professionals and offered to cigarette smokers and smokeless tobacco users in the dental office or community setting. Search methods We searched the Cochrane Tobacco Addiction Group Specialized Register (CENTRAL), MEDLINE (1966-November 2011), EMBASE (1988-November 2011), CINAHL (1982-November 2011), Healthstar (1975-November 2011), ERIC (1967-November 2011), PsycINFO (1984-November 2011), National Technical Information Service database (NTIS, 1964-November 2011), Dissertation Abstracts Online (1861-November 2011), Database of Abstract of Reviews of Effectiveness (DARE, 1995-November 2011), and Web of Science (1993-November 2011). Selection criteria We included randomized and pseudo-randomized clinical trials assessing tobacco cessation interventions conducted by oral health professionals in the dental office or community setting with at least six months of follow-up. Data collection and analysis Two authors independently reviewed abstracts for potential inclusion and abstracted data from included trials. Disagreements were resolved by consensus. The primary outcome was abstinence from smoking or all tobacco use (for users of smokeless tobacco) at the longest follow-up, using the strictest definition of abstinence reported. The effect was summarised as an odds ratio, with correction for clustering where appropriate. Heterogeneity was assessed using the I2 statistic and where appropriate a pooled effect was estimated using an inverse variance fixed-effect model. Main results Fourteen clinical trials met the criteria for inclusion in this review. Included studies assessed the efficacy of interventions in the dental office or in a community school or college setting. Six studies evaluated the effectiveness of interventions among smokeless tobacco (ST) users, and eight studies evaluated interventions among cigarette smokers, six of which involved adult smokers in dental practice settings. All studies employed behavioral interventions and only one required pharmacotherapy as an interventional component. All studies included an oral examination component. Pooling all 14 studies suggested that interventions conducted by oral health professionals can increase tobacco abstinence rates (odds ratio [OR] 1.71, 95% confidence interval [CI] 1.44 to 2.03) at six months or longer, but there was evidence of heterogeneity (I2 = 61%). Within the subgroup of interventions for smokers, heterogeneity was smaller (I2 = 51%), but was largely attributable to a large study showing no evidence of benefit. Within this subgroup there were five studies which involved adult smokers in dental practice settings. Pooling these showed clear evidence of benefit and minimal heterogeneity (OR 2.38, 95% CI 1.70 to 3.35, 5 studies, I2 = 3%) but this was a posthoc subgroup analysis. Amongst the studies in smokeless tobacco users the heterogeneity was also attributable to a large study showing no sign of benefit, possibly due to intervention spillover to control colleges; the other five studies indicated that interventions for ST users were effective (OR 1.70; 95% CI 1.36 to 2.11). Authors’ conclusions Available evidence suggests that behavioral interventions for tobacco cessation conducted by oral health professionals incorporating an oral examination component in the dental office or community setting may increase tobacco abstinence rates among both cigarette smokers and smokeless tobacco users. Differences between the studies limit the ability to make conclusive recommendations regarding the intervention components that should be incorporated into clinical practice, however, behavioral counselling (typically brief) in conjunction with an oral examination was a consistent intervention component that was also provided in some control groups.

Unified Photo Enhancement by Discovering Aesthetic Communities From Flickr.

PubMed

Hong, Richang; Zhang, Luming; Tao, Dacheng

2016-03-01

Photo enhancement refers to the process of increasing the aesthetic appeal of a photo, such as changing the photo aspect ratio and spatial recomposition. It is a widely used technique in the printing industry, graphic design, and cinematography. In this paper, we propose a unified and socially aware photo enhancement framework which can leverage the experience of photographers with various aesthetic topics (e.g., portrait and landscape). We focus on photos from the image hosting site Flickr, which has 87 million users and to which more than 3.5 million photos are uploaded daily. First, a tagwise regularized topic model is proposed to describe the aesthetic topic of each Flickr user, and coherent and interpretable topics are discovered by leveraging both the visual features and tags of photos. Next, a graph is constructed to describe the similarities in aesthetic topics between the users. Noticeably, densely connected users have similar aesthetic topics, which are categorized into different communities by a dense subgraph mining algorithm. Finally, a probabilistic model is exploited to enhance the aesthetic attractiveness of a test photo by leveraging the photographic experiences of Flickr users from the corresponding communities of that photo. Paired-comparison-based user studies show that our method performs competitively on photo retargeting and recomposition. Moreover, our approach accurately detects aesthetic communities in a photo set crawled from nearly 100000 Flickr users.

Climate Change on Twitter: Topics, Communities and Conversations about the 2013 IPCC Working Group 1 Report

2014-01-01

In September 2013 the Intergovernmental Panel on Climate Change published its Working Group 1 report, the first comprehensive assessment of physical climate science in six years, constituting a critical event in the societal debate about climate change. This paper analyses the nature of this debate in one public forum: Twitter. Using statistical methods, tweets were analyzed to discover the hashtags used when people tweeted about the IPCC report, and how Twitter users formed communities around their conversational connections. In short, the paper presents the topics and tweeters at this particular moment in the climate debate. The most used hashtags related to themes of science, geographical location and social issues connected to climate change. Particularly noteworthy were tweets connected to Australian politics, US politics, geoengineering and fracking. Three communities of Twitter users were identified. Researcher coding of Twitter users showed how these varied according to geographical location and whether users were supportive, unsupportive or neutral in their tweets about the IPCC. Overall, users were most likely to converse with users holding similar views. However, qualitative analysis suggested the emergence of a community of Twitter users, predominantly based in the UK, where greater interaction between contrasting views took place. This analysis also illustrated the presence of a campaign by the non-governmental organization Avaaz, aimed at increasing media coverage of the IPCC report. PMID:24718388

Opportunities to travel from one place to another in the community, or community mobility, are especially important for mobility device users' ability to participate fully in society. However, contextual challenges to such mobility exist. This study summarizes the literature on existing community mobility barriers and facilitators of mobility device users created by services, systems, and policies as defined by the International Classification of Functioning, Disability, and Health (ICF). Arksey and O'Malley's approach for scoping studies was used for the review. The extraction chart was organized following the ICF, and frequency counts were used to report the data. The findings suggest that certain factors, such as transportation, open-space planning, and architecture and construction, influence community mobility opportunities. However, little attention has been paid to services, systems, and policies in the research literature, limiting the knowledge on the subject. Further research is needed to examine the relationship between specific services, systems, and policies and mobility device users' mobility within their communities.

Non-adherence is a major obstacle to optimal treatment of schizophrenia. Community pharmacists are in a key position to detect non-adherence and put in place interventions. Their role is likely to be more efficient when individuals are loyal to a single pharmacy. To assess the association between the level of community pharmacy loyalty and persistence with and implementation of antipsychotic drug treatment among individuals with schizophrenia. A cohort study using databases from the Quebec health insurance board (Canada) was conducted among new antipsychotic users insured by Quebec's public drug plan. Level of community pharmacy loyalty was assessed as the number of pharmacies visited in the year after antipsychotics initiation. Persistence was defined as having an antipsychotic supply in the user's possession on the 730 th day after its initiation and implementation as having antipsychotics in the user's possession for ≥80% of the days in the second year after antipsychotics initiation (among persistent only). Generalized linear models were used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (95%CI). 6,251 individuals were included in the cohort and 54.1% had their drug prescriptions filled in >1 pharmacy. When compared to those who had their prescriptions filled in a single pharmacy, those who had their prescriptions filled in ≥4 different pharmacies were 22% more likely to be non-persistent (aPR = 1.22; 95%CI = 1.10-1.37) and 49% more likely to have an antipsychotic for <80% of the days (aPR = 1.49; 95%IC = 1.28-1.74). This first exploration of community pharmacy loyalty in the context of severe mental illness indicates that this healthcare organisation factor might be associated with antipsychotics persistence and implementation. Identification of individuals with low community pharmacy loyalty and initiatives to optimize community pharmacy loyalty could contribute to enhanced persistence and implementation.

This study explored underlying reasons for the expression of dissatisfaction with services among Bangladeshi and Pakistani social care users in England and investigated, using a collaborative approach, how these could be addressed. In-depth interviews were conducted in Birmingham, Leeds and London during 2012-2013 with 63 Bangladeshi, Pakistani and white British service users and 24 social care managers, social workers and care workers. A further 34 cognitive interviews were conducted within the same study. Following data analysis, three collaborative workshops involving service users and providers were held to validate the findings and to draw out policy and practice recommendations. Analysis of the cognitive interviews showed that higher dissatisfaction among Bangladeshi and Pakistani service users reported in social care surveys was not due to questionnaire design. Instead in-depth interviews showed that dissatisfaction across all three groups was expressed along the social care journey, including accessing care, communication with social workers and the nature of care received. While many issues were common to all three groups, cultural differences also emerged as affecting experiences of social care. These included misunderstandings about family roles in care; gender issues, especially relating to women; language and communication barriers, alongside the need for a more nuanced approach to ethnic 'matching'; and continuing limited cultural understanding among care workers. The collaborative workshops identified practical actions that could address some of the issues identified. These covered raising awareness of services within communities; improving support for informal carers; service user input to assessments; consistent and ongoing sharing of information; improving access; and more efforts to diversify and appropriately train the social care workforce. In conclusion, the paper presents the reality of dissatisfaction among these groups and argues for more action involving communities and service providers to address these persistent issues collaboratively. © 2016 John Wiley & Sons Ltd.

Current accounts of spatial cyberinfrastructure development tend to overemphasize technologies to the neglect of critical social and cultural issues on which adoption depends. Spatial cyberinfrastructures will have a higher chance of success if users of many types, including nonprofessionals, are made central to the development process. Recent studies in the history of infrastructures reveal key turning points and issues that should be considered in the development of spatial cyberinfrastructure projects. These studies highlight the importance of adopting qualitative research methods to learn how users work with data and digital tools, and how user communities form. The author's empirical research on data sharing networks in the Pacific Northwest salmon crisis at the turn of the 21st century demonstrates that ordinary citizens can contribute critical local knowledge to global databases and should be considered in the design and construction of spatial cyberinfrastructures.

The language of community is ubiquitous in academic, public health, and policy discourse about drug using populations. Yet, it has been argued that in some settings, the parameters of “the drug user community” are far from self-evident. We undertook this ethnographic investigation to explore experiences and understandings of a “drug user community” (sometimes referred to more specifically as a “street youth community”) among young people entrenched in Vancouver’s inner city drug scene. Our findings revealed that in this context, conventional notions of community—that is, a social network characterized by commonality, mutual responsibility, solidarity, and/or stability—resonated with some youth. However, most questioned the value of membership within this community, in which what they had in common with other youth were ongoing experiences of poverty, marginalization, and social exclusion. Many felt membership in the drug user community precluded their ability to be responsible and productive citizens within the wider community of “mainstream society.” Experiences of resource deprivation and everyday violence on the streets led many participants to emphasize the limited possibilities for community among their peers. We argue that it is important to critically examine heretofore essentializing assumptions about the nature of inner city drug user or street youth communities in order to better understand young people’s needs and desires in these settings.

Promoting scientific collaboration and research through integrated social networking capabilities within the OpenTopography Portal

Nandigam, V.; Crosby, C. J.; Baru, C.

2009-04-01

LiDAR (Light Distance And Ranging) topography data offer earth scientists the opportunity to study the earth's surface at very high resolutions. As a result, the popularity of these data is growing dramatically. However, the management, distribution, and analysis of community LiDAR data sets is a challenge due to their massive size (multi-billion point, mutli-terabyte). We have also found that many earth science users of these data sets lack the computing resources and expertise required to process these data. We have developed the OpenTopography Portal to democratize access to these large and computationally challenging data sets. The OpenTopography Portal uses cyberinfrastructure technology developed by the GEON project to provide access to LiDAR data in a variety of formats. LiDAR data products available range from simple Google Earth visualizations of LiDAR-derived hillshades to 1 km2 tiles of standard digital elevation model (DEM) products as well as LiDAR point cloud data and user generated custom-DEMs. We have found that the wide spectrum of LiDAR users have variable scientific applications, computing resources and technical experience and thus require a data system with multiple distribution mechanisms and platforms to serve a broader range of user communities. Because the volume of LiDAR topography data available is rapidly expanding, and data analysis techniques are evolving, there is a need for the user community to be able to communicate and interact to share knowledge and experiences. To address this need, the OpenTopography Portal enables social networking capabilities through a variety of collaboration tools, web 2.0 technologies and customized usage pattern tracking. Fundamentally, these tools offer users the ability to communicate, to access and share documents, participate in discussions, and to keep up to date on upcoming events and emerging technologies. The OpenTopography portal achieves the social networking capabilities by integrating various software technologies and platforms. These include the Expression Engine Content Management System (CMS) that comes with pre-packaged collaboration tools like blogs and wikis, the Gridsphere portal framework that contains the primary GEON LiDAR System portlet with user job monitoring capabilities and a java web based discussion forum (Jforums) application all seamlessly integrated under one portal. The OpenTopography Portal also provides integrated authentication mechanism between the various CMS collaboration tools and the core gridsphere based portlets. The integration of these various technologies allows for enhanced user interaction capabilities within the portal. By integrating popular collaboration tools like discussion forums and blogs we can promote conversation and openness among users. The ability to ask question and share expertise in forum discussions allows users to easily find information and interact with users facing similar challenges. The OpenTopography Blog enables our domain experts to post ideas, news items, commentary, and other resources in order to foster discussion and information sharing. The content management capabilities of the portal allow for easy updates to information in the form of publications, documents, and news articles. Access to the most current information fosters better decision-making. As has become the standard for web 2.0 technologies, the OpenTopography Portal is fully RSS enabled to allow users of the portal to keep track of news items, forum discussions, blog updates, and system outages. We are currently exploring how the information captured by user and job monitoring components of the Gridsphere based GEON LiDAR System can be harnessed to provide a recommender system that will help users to identify appropriate processing parameters and to locate related documents and data. By seamlessly integrating the various platforms and technologies under one single portal, we can take advantage of popular online collaboration tools that are either stand alone or software platform restricted. The availability of these collaboration tools along with the data will foster more community interaction and increase the strength and vibrancy of the LiDAR topography user community.

Designing the user interface: strategies for effective human-computer interaction

NASA Astrophysics Data System (ADS)

Shneiderman, B.

1998-03-01

In revising this popular book, Ben Shneiderman again provides a complete, current and authoritative introduction to user-interface design. The user interface is the part of every computer system that determines how people control and operate that system. When the interface is well designed, it is comprehensible, predictable, and controllable; users feel competent, satisfied, and responsible for their actions. Shneiderman discusses the principles and practices needed to design such effective interaction. Based on 20 years experience, Shneiderman offers readers practical techniques and guidelines for interface design. He also takes great care to discuss underlying issues and to support conclusions with empirical results. Interface designers, software engineers, and product managers will all find this book an invaluable resource for creating systems that facilitate rapid learning and performance, yield low error rates, and generate high user satisfaction. Coverage includes the human factors of interactive software (with a new discussion of diverse user communities), tested methods to develop and assess interfaces, interaction styles such as direct manipulation for graphical user interfaces, and design considerations such as effective messages, consistent screen design, and appropriate color.

#Stupidcancer: Exploring a Typology of Social Support and the Role of Emotional Expression in a Social Media Community.

Myrick, Jessica Gall; Holton, Avery E; Himelboim, Itai; Love, Brad

2016-01-01

Social network sites (SNSs) like Twitter continue to attract users, many of whom turn to these spaces for social support for serious illnesses like cancer. Building on literature that explored the functionality of online spaces for health-related social support, we propose a typology that situates this type of support in an SNS-based open cancer community based on the type (informational or emotional) and the direction (expression or reception) of support. A content analysis applied the typology to a 2-year span of Twitter messages using the popular hashtag "#stupidcancer." Given that emotions form the basis for much of human communication and behavior, including aspects of social support, this content analysis also examined the relationship between emotional expression and online social support in tweets about cancer. Furthermore, this study looked at the various ways in which Twitter allows for message sharing across a user's entire network (not just among the cancer community). This work thus begins to lay the conceptual and empirical groundwork for future research testing the effects of various types of social support in open, interactive online cancer communities.

The results of a survey of the ocean/coastal zone community to determine potential applications of a High Altitude Powered Platform (HAPP) are reported. Such a platform, capable of stationkeeping for periods up to a year over a given location, could make frequent and repeated high resolution observations over a given region or serve as a high-altitude regional communications link. Users were surveyed in person and via a questionnaire to determine the desirability of the HAPP within the ocean/coastal zone community. The results of the survey indicated that there is strong interest in all areas of the user community (research and development, operational agencies, and private industry) in having NASA develop the HAPP.

Despite the potential benefits of social media, health care providers are often hesitant to engage patients through these sites. Our aim was to explore how implementation of social media may affect patient engagement and satisfaction. In September 2016 a Facebook support group was created for liver transplant patients to use as a virtual community forum. Data including user demographics and group activity were reviewed. A survey was conducted evaluating users' perceptions regarding participation in the group. Over 9 months, 350 unique users (50% liver transplant patients, 36% caregivers/friends, 14% health care providers) contributed 339 posts, 2,338 comments, and 6,274 reactions to the group; 98% of posts were reacted to or commented on by other group members. Patients were the most active users compared with health care providers and caregivers. A total of 95% of survey respondents reported that joining the group had a positive impact on their care; and 97% reported that their main motivation for joining was to provide or receive support from other patients. This pilot study indicates that the integration of social media into clinical practice can empower surgeons to synthesize effectively a patient support community that augments patient engagement and satisfaction.

Food insecurity is a chronic problem affecting Inuit communities. The most comprehensive assessment of Inuit food security to-date, the Inuit Health Survey, reported that 70% of Inuit pre-school children lived in 'food insecure' households. Food banks and soup kitchens are relatively new in the Arctic but the number of users is increasing. Little is known about the experience and determinants of food insecurity among food program users who are often among the most marginalized (socially and economically) in communities. The use of participatory research methods when working in the north of Canada can promote meaningful knowledge exchange with community members and this approach was used in the present 'Photovoice' research. Photovoice uses photography to develop a baseline understanding of an issue, in this case the experience and determinants of food insecurity among users of community food programs in Iqaluit, Nunavut. The target population includes those who face significant social and economic marginalization, an often neglected group in Arctic food systems research. Eight regular users of food programs were recruited and engaged in a Photovoice research project to document factors determining their daily food consumption. The research method was introduced in workshops and discussion included the ethical concerns related to photography and how to take pictures. Participants were supplied with digital cameras, and asked to answer the following question using photography: 'What aspects of your everyday life affect what you eat and how much you have to eat?'. In the final workshop, photographs were discussed among the group and participants identified key themes in the photographs, offering an understanding of food insecurity from their perspectives. The group then discussed what should be done with the knowledge gained. Factors improving food security were the customary systems for sharing 'country food', and the presence of social support networks in the community, such as the Food Bank, the Soup Kitchen and the Tukisigiarvik Center. Factors identified as negatively affecting food security were the high cost of food in the Arctic, and substance abuse. The participants decided by consensus whether and how the knowledge from this project would be disseminated. They decided that a museum exhibit of the photographs in the summer of 2010 and promotion of the results among policy-makers in Nunavut were of high priority. The use of participatory research approaches such as Photovoice offers promise for exploring food security issues among similarly disadvantaged and vulnerable populations elsewhere in the Arctic. This approach was found to be a useful method for gathering and sharing research data because the data was generated and analysed by the participants. The clear and concise messages developed by the participants can be used to inform policy. This research method can assist in making a valuable contribution to health research, both in the Arctic and worldwide, because it promotes an understanding of the experiences of individuals from their own perspective.

The emergence of e-Science over the past decade as a paradigm for Internet-based science was an inevitable evolution of science that built upon the web protocols and access patterns that were prevalent at that time, including Web Services, XML-based information exchange, machine-to-machine communication, service registries, the Grid, and distributed data. We now see a major shift in web behavior patterns to social networks, user-provided content (e.g., tags and annotations), ubiquitous devices, user-centric experiences, and user-led activities. The inevitable accrual of these social networking patterns and protocols by scientists and science projects leads to U-Science as a new paradigm for online scientific research (i.e., ubiquitous, user-led, untethered, You-centered science). U-Science applications include components from semantic e-science (ontologies, taxonomies, folksonomies, tagging, annotations, and classification systems), which is much more than Web 2.0-based science (Wikis, blogs, and online environments like Second Life). Among the best examples of U-Science are Citizen Science projects, including Galaxy Zoo, Stardust@Home, Project Budburst, Volksdata, CoCoRaHS (the Community Collaborative Rain, Hail and Snow network), and projects utilizing Volunteer Geographic Information (VGI). There are also scientist-led projects for scientists that engage a wider community in building knowledge through user-provided content. Among the semantic-based U-Science projects for scientists are those that specifically enable user-based annotation of scientific results in databases. These include the Heliophysics Knowledgebase, BioDAS, WikiProteins, The Entity Describer, and eventually AstroDAS. Such collaborative tagging of scientific data addresses several petascale data challenges for scientists: how to find the most relevant data, how to reuse those data, how to integrate data from multiple sources, how to mine and discover new knowledge in large databases, how to represent and encode the new knowledge, and how to curate the discovered knowledge. This talk will address the emergence of U-Science as a type of Semantic e-Science, and will explore challenges, implementations, and results. Semantic e-Science and U-Science applications and concepts will be discussed within the context of one particular implementation (AstroDAS: Astronomy Distributed Annotation System) and its applicability to petascale science projects such as the LSST (Large Synoptic Survey Telescope), coming online within the next few years.

Modern molecular methods have increased our ability to describe microbial communities. Along with the advances brought by new sequencing technologies, we now require intensive computational resources to make sense of the large numbers of sequences continuously produced. The software developed by the scientific community to address this demand, although very useful, require experience of the command-line environment, extensive training and have steep learning curves, limiting their use. We created SEED 2, a graphical user interface for handling high-throughput amplicon-sequencing data under Windows operating systems. SEED 2 is the only sequence visualizer that empowers users with tools to handle amplicon-sequencing data of microbial community markers. It is suitable for any marker genes sequences obtained through Illumina, IonTorrent or Sanger sequencing. SEED 2 allows the user to process raw sequencing data, identify specific taxa, produce of OTU-tables, create sequence alignments and construct phylogenetic trees. Standard dual core laptops with 8 GB of RAM can handle ca. 8 million of Illumina PE 300 bp sequences, ca. 4GB of data. SEED 2 was implemented in Object Pascal and uses internal functions and external software for amplicon data processing. SEED 2 is a freeware software, available at http://www.biomed.cas.cz/mbu/lbwrf/seed/ as a self-contained file, including all the dependencies, and does not require installation. Supplementary data contain a comprehensive list of supported functions. daniel.morais@biomed.cas.cz. Supplementary data are available at Bioinformatics online. © The Author(s) 2018.

Lowering Entry Barriers for Multidisciplinary Cyber(e)-Infrastructures

Nativi, S.

2012-04-01

Multidisciplinarity is more and more important to study the Earth System and address Global Changes. To achieve that, multidisciplinary cyber(e)-infrastructures are an important instrument. In the last years, several European, US and international initiatives have been started to carry out multidisciplinary infrastructures, including: the Spatial Information in the European Community (INSPIRE), the Global Monitoring for Environment and Security (GMES), the Data Observation Network for Earth (DataOne), and the Global Earth Observation System of Systems (GEOSS). The majority of these initiatives are developing service-based digital infrastructures asking scientific Communities (i.e. disciplinary Users and data Producers) to implement a set of standards for information interoperability. For scientific Communities, this has represented an entry barrier which has proved to be high, in several cases. In fact, both data Producers and Users do not seem to be willing to invest precious resources to become expert on interoperability solutions -on the contrary, they are focused on developing disciplinary and thematic capacities. Therefore, an important research topic is lowering entry barriers for joining multidisciplinary cyber(e)-Infrastructures. This presentation will introduce a new approach to achieve multidisciplinary interoperability underpinning multidisciplinary infrastructures and lowering the present entry barriers for both Users and data Producers. This is called the Brokering approach: it extends the service-based paradigm by introducing a new a Brokering layer or cloud which is in charge of managing all the interoperability complexity (e.g. data discovery, access, and use) thus easing Users' and Producers' burden. This approach was successfully experimented in the framework of several European FP7 Projects and in GEOSS.

Over the last several years the availability of geospatial data has evolved from a scarce and expensive resource, primarily provided by governmental organizations to an abundant resource, often sourced at no or minimum charge by a much broader community including citizen scientists. In an upcoming workshop (October 28/29, 2014), the consequences of the changing technology, data, and policy landscape will be examined thus evaluating the emerging new data-driven paradigms, and advancing the state-of-the-art methodologies to measure the resulting socioeconomic impacts. Providers and users of geospatial data span a broad range of multi-disciplinary areas include policy makers and analysts, financial analysts, economists, geospatial practitioners and other experts from government, academia and the private sector. This presentation will focus on the emerging plan for a sustained, multi-disciplinary community to identify and pursue exemplary use cases for further research and applications. Considerations will include the necessary outreach enablers for such a project.

We estimated the causal effects of use of an online smoking cessation community on 30-day point prevalence abstinence at 3 months. Participants (N = 492) were adult current smokers in the enhanced Internet arm of The iQUITT Study, a randomized trial of Internet and telephone treatment for smoking cessation. All participants accessed a Web-based smoking-cessation program that included a large, established online community. Automated tracking metrics of passive (e.g., reading forum posts, viewing member profiles) and active (e.g., writing forum posts, sending private messages) community use were extracted from the site at 3 months. Self-selected community use defines the groups of interest: "None," "Passive," and "Both" (passive + active). Inverse probability of treatment weighting corrected for baseline imbalances on demographic, smoking, psychosocial, and medical history variables. Propensity weights estimated via generalized boosted models were used to calculate Average Treatment Effects (ATE) and Average Treatment effects on the Treated (ATT). Patterns of community use were: None = 198 (40.2%), Passive = 110 (22.4%), and Both = 184 (37.4%). ATE-weighted abstinence rates were: None = 4.2% (95% CI = 1.5-6.9); Passive = 15.1% (95% CI = 8.4-21.9); Both = 20.4% (95% CI = 13.9-26.8). ATT-weighted abstinence rates indicated even greater benefits of community use. Community users were more likely to quit smoking at 3 months than nonusers. The estimated benefit from use of online community resources was even larger among subjects with high propensity to use them. No differences in abstinence emerged between passive and passive/active users. Results suggest that lurking in online communities confers specific abstinence benefits. Implications of these findings for online cessation communities are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

More than 200,000 individuals worldwide have received a cochlear implant (CI). Social media Websites may provide a paramedical community for those who possess or are interested in a CI. The utilization patterns of social media by the CI community, however, have not been thoroughly investigated. The purpose of this study was to investigate participation of the CI community in social media Websites. We conducted a systematic survey of online CI-related social media sources. Using standard search engines, the search terms cochlear implant, auditory implant, forum, and blog identified relevant social media platforms and Websites. Social media participation was quantified by indices of membership and posts. Social media sources included Facebook, Twitter, YouTube, blogs, and online forums. Each source was assigned one of six functional categories based on its description. No intervention was performed. We conducted all online searches in February 2014. Total counts of each CI-related social media source were summed, and descriptive statistics were calculated. More than 350 sources were identified, including 60 Facebook groups, 36 Facebook pages, 48 Twitter accounts, 121 YouTube videos, 13 forums, and 95 blogs. The most active online communities were Twitter accounts, which totaled 35,577 members, and Facebook groups, which totaled 17,971 members. CI users participated in Facebook groups primarily for general information/support (68%). Online forums were the next most active online communities by membership. The largest forum contained approximately 9,500 topics with roughly 127,000 posts. CI users primarily shared personal stories through blogs (92%), Twitter (71%), and YouTube (62%). The CI community engages in the use of a wide range of online social media sources. The CI community uses social media for support, advocacy, rehabilitation information, research endeavors, and sharing of personal experiences. Future studies are needed to investigate how social media Websites may be harnessed to improve patient-provider relationships and potentially used to augment patient education.

At CERN a number of key database applications are running on user-managed MySQL database services. The database on demand project was born out of an idea to provide the CERN user community with an environment to develop and run database services outside of the actual centralised Oracle based database services. The Database on Demand (DBoD) empowers the user to perform certain actions that had been traditionally done by database administrators, DBA's, providing an enterprise platform for database applications. It also allows the CERN user community to run different database engines, e.g. presently open community version of MySQL and single instance Oracle database server. This article describes a technology approach to face this challenge, a service level agreement, the SLA that the project provides, and an evolution of possible scenarios.

Background In response to the overdose epidemic, a network of support groups for family members in Massachusetts has been providing overdose education and naloxone rescue kits (OEN). The aims of this study were to describe the characteristics, motivations and benefits of family members who receive OEN and to describe the frequency of naloxone used during an overdose rescue. Methods This cross-sectional, multisite study surveyed attendees of community support groups for family members of opioid users where OEN training was offered using a 42 item self-administered survey that included demographics, relationship to opioid user, experience with overdose, motivations to receive OEN, and naloxone rescue kit use. Results Of 126 attendees who completed surveys at 8 sites, most attendees were white (95%), female (78%), married or partnered (74%), parents of an opioid user (85%), and provide financial support for opioid user (52%). The OEN trainees (79%) were more likely than attendees not trained (21%) to be parents of an opioid user (91% v 65%, p <0.05), provide financial support to an opioid user (58% v 30%, p <0.05), and to have witnessed an overdose (35% v 12%, p=0.07). The major motivations to receive training were: wanting a kit in their home (72%), education provided at the meeting (60%) and hearing about benefits from others (57%). Sixteen parents reported witnessing their child overdose and five attendees had used naloxone successfully during an overdose rescue. Conclusions Support groups for families of people who use opioids are promising venues to conduct overdose prevention trainings, because attendees are motivated to receive training and will use naloxone to rescue people when witnessing an overdose. Further study is warranted to understand how to optimize this approach to overdose prevention in the community setting. PMID:25564892

Smartphone health applications ('apps') are widely available but experts remain cautious about their utility and safety. We reviewed currently available apps for the detection of melanoma (July 2014), aimed at general community, patient and generalist clinician users. A proforma was used to extract and assess each app that met the inclusion criteria, and we undertook content analysis to evaluate their content and the evidence applied in their development. Thirty-nine apps were identified with the majority available only for Apple users. Over half (n = 22) provided information or education about melanoma, ultraviolet radiation exposure prevention advice, and skin self-examination strategies, mainly using the ABCDE (A, Asymmetry; B, Border; C, Colour; D, Diameter; E, Evolving) method. Half (n = 19) helped users take and store images of their skin lesions either for review by a dermatologist or for self-monitoring to identify change, an important predictor of melanoma; a similar number (n = 18) used reminders to help users monitor their skin lesions. A few (n = 9) offered expert review of images. Four apps provided a risk assessment to patients about the probability that a lesion was malignant or benign, and one app calculated users' future risk of melanoma. None of the apps appeared to have been validated for diagnostic accuracy or utility using established research methods. Smartphone apps for detecting melanoma by nonspecialist users have a range of functions including information, education, classification, risk assessment and monitoring change. Despite their potential usefulness, and while clinicians may choose to use apps that provide information to educate their patients, apps for melanoma detection require further validation of their utility and safety. © 2015 The Authors.

Background Numerous publications demonstrate the importance of community-based participatory research (CBPR) in community health research, but few target the Deaf community. The Deaf community is understudied and underrepresented in health research despite suspected health disparities and communication barriers. Objectives The goal of this paper is to share the lessons learned from the implementation of CBPR in an understudied community of Deaf American Sign Language (ASL) users in the greater Rochester, New York, area. Methods We review the process of CBPR in a Deaf ASL community and identify the lessons learned. Results Key CBPR lessons include the importance of engaging and educating the community about research, ensuring that research benefits the community, using peer-based recruitment strategies, and sustaining community partnerships. These lessons informed subsequent research activities. Conclusions This report focuses on the use of CBPR principles in a Deaf ASL population; lessons learned can be applied to research with other challenging-to-reach populations. PMID:22982845

The growth of social networking services has enabled the sharing of electronic cigarette opinions and experiences via user-generated content. This exploratory study analyzed electronic cigarette content found on the visual social networking service, Instagram, in order to highlight public health challenges created by this content and support understanding of electronic cigarette promotion and usage. A qualitative content analysis was performed on Instagram posts made with the hashtags #ecig or #vape in October 2014. Images, text, and hashtags from 85 posts (43 #ecig, 42 #vape) were analyzed. In addition, the total number of posts made with eight key electronic cigarette hashtags was recorded at four points between March 2014 and October 2015. The total number of #vape posts on Instagram grew by 4,163,274 during the study period, while #ecig posts increased by 741,916. Of the posts examined in-depth, corporate users made up over half of posts. No posts were critical of electronic cigarettes. Few mentioned electronic cigarettes in the context of health benefits. No posts included major brands, and mod style electronic cigarettes were mentioned or depicted in over half of posts. A majority of posts included hashtags expressing vaping identity and community. In addition, users mentioned novel practices such as sub-ohming. Conclusions/Importance: Instagram users in our sample characterized electronic cigarettes primarily as novel devices rather than equivalents to cigarettes. Further, hashtag communities and identities appear to be forming around vaping. Future research should consider the public health implications of these hashtags, as well as novel electronic cigarette practices.

“Nothing is free”: A qualitative study of sex trading among methamphetamine users in Cape Town, South Africa

South Africa is facing an established epidemic of methamphetamine, known locally as “tik”. Globally, methamphetamine has been linked to high rates of sexual risk behaviors, including sex trading. The goal of this study was to qualitatively examine the experiences of sex trading among methamphetamine users in Cape Town, South Africa. Individual in-depth interviews were conducted with 30 active methamphetamine users (17 men and 13 women) recruited from the community. Interviews were conducted in local languages using a semi-structured guide that included questions on sex trading experiences and perceptions of sex trading among methamphetamine users. Interviews were audio-recorded, transcribed, and analyzed using analytic memos and coding with constant comparison techniques. The data revealed that in a setting of high levels of addiction and poverty, sex was an important commodity for acquiring methamphetamine. Women were more likely to use sex to acquire methamphetamine, but men reported opportunistic cases of trading sex for methamphetamine. Four models of sex trading emerged: negotiated exchange, implicit exchange, relationships based on resources, and facilitating sex exchange for others. The expectation of sex trading created a context in which sexual violence against female methamphetamine users was common. Multiple sexual partners and inconsistent condom use in acts of sex trading put methamphetamine users at high risk of HIV. Interventions in this setting should address addiction, which is the primary driver of sex trading among methamphetamine users. Harm reduction interventions may include education about HIV and other sexually transmitted infections, availability of condoms and HIV testing, and sexual violence prevention. PMID:25567071

Science software is integral to the scientific process and must be developed and managed in a sustainable manner to ensure future access to scientific data and related resources. Organizations that are part of the scientific enterprise, as well as members of the scientific community who work within these entities, can contribute to the sustainability of science software and to practices that improve scientific community capabilities for science software sustainability. As science becomes increasingly digital and therefore, dependent on software, improving community practices for sustainable science software will contribute to the sustainability of science. Members of the Earth science informatics community, including scientific data producers and distributers, end-user scientists, system and application developers, and data center managers, use science software regularly and face the challenges and the opportunities that science software presents for the sustainability of science. To gain insight on practices needed for the sustainability of science software from the science software experiences of the Earth science informatics community, an interdisciplinary group of 300 community members were asked to engage in simultaneous roundtable discussions and report on their answers to questions about the requirements for improving scientific software sustainability. This paper will present an analysis of the issues reported and the conclusions offered by the participants. These results provide perspectives for science software sustainability practices and have implications for actions that organizations and their leadership can initiate to improve the sustainability of science software.

Dependence and resistance in community mental health care-Negotiations of user participation between staff and users.

PubMed

Femdal, I; Knutsen, I R

2017-10-01

WHAT IS KNOWN ON THE SUBJECT?: Implementation of user participation is described as a change from a paternalistic healthcare system to ideals of democratization where users' voices are heard in relational interplays with health professionals. The ideological shift involves a transition from welfare dependency and professional control towards more active service-user roles with associated rights and responsibilities. A collaborative relationship between users and professionals in mental health services is seen as important by both parties. Nevertheless, the health professionals find it challenging in practice to reorient their roles and to find productive ways to cooperate. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study illuminates how user participation is negotiated and involves multiple and shifting subject positions in the collaboration between users and professionals in community mental health care. By taking different positions, the relationship between users and professionals develops through dynamic interaction. This study challenges understandings of equality and implicit "truths" in user participation by illuminating subtle forms of power and dilemmas that arise in user-professional negotiations. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Instead of denying the appearance of power, it is important to question the execution of power in the interplay between users and professionals. Focusing on the negotiation processes between users and professionals is important for increasing reflection on and improving understanding of the dynamic in collaboration and speech. By focusing on negotiations, power can be used in productive ways in user-professional relationships. Introduction Implementation of user participation is considered important in today's mental health care. Research shows, however, that user participation lacks clarity and provokes uncertainty regarding shifting roles. Aim To investigate negotiation of user participation in a microstudy of interplay between users and health professionals in community mental health care. Method This qualitative study is based on semi-structured in-depth interviews, involving ten service users and ten professionals in community mental health care in Norway. The analysis is inspired by Willig's model for Foucauldian discourse analysis. Results The study illuminates the dynamic nature of user participation that arises through negotiation between users' and professionals' positions as change enablers, dependents, resisters, persuaders and knowledge holders. Discussion Discourses of user participation allow for different subject positions in mental health care. User participation also involves government and questions of power, as well as ambitions of change and control. Professionals act in different ways to make and keep users active, participating, enterprising and self-governing, and users respond and take part within the same discursive framework. Implications for practice Awareness of subjects' positions in discourses is important to increase reflection on the dynamic interplay in user-professional collaboration. © 2017 John Wiley & Sons Ltd.

Detection of adverse drug reactions among ordinary users of liraglutide on the occasion of drug dispensing in the community pharmacy setting.

2013-12-01

Postmarketing studies of drugs forms an essential part of safety surveillance. In particular, this concerns new drugs as safety information of these by large rests on randomized clinical studies conducted on a limited number of subjects before licensing. Pharmacists in community pharmacies are in a unique position for detection of user experienced adverse drug reactions (ADRs) in relation to drug dispensing. The study reports from a research initiative exploring prompt and proactive ADR detection of liraglutide and reporting facilitated by pharmacy students undertaking internship in a community pharmacy in Denmark. Nineteen pharmacy students undertaking regular 6 months' internship--eighth semester--in a Danish community pharmacy participated in the data collection. Before the data collection, students attended an interactive training seminar addressing ADRs in general, organ symptoms, diagnostic classification, and pharmacovigilance systems. Pharmacy students approached recurrent drug users purchasing liraglutide. Participating users were asked about experienced ADRs linked to liraglutide use. Reported ADRs were collected and analyzed. Sixty-two liraglutide users participated in the study, of whom, 38 reported 84 ADRs possibly linked to liraglutide usage. Nausea was by far the most reported ADR followed by decreased appetite, diarrhea, fatigue, and abdominal pain (upper). The reported ADRs are in accordance with previously reported ADRs. The study has demonstrated the feasibility of community pharmacy driven pharmacovigilance. The study supports the thesis that community pharmacists in the future may play a proactive and prominent role in patient-centered pharmacovigilance.

While relatively rare events, abrupt disruptions in heroin availability have a significant impact on morbidity and mortality risk among those who are heroin dependent. A heroin shortage occurred in Coast Province, Kenya from December 2010 to March 2011. This qualitative analysis describes the shortage events and consequences from the perspective of heroin users, along with implications for health and other public sectors. As part of a rapid assessment, 66 key informant interviews and 15 focus groups among heroin users in Coast Province, Kenya were conducted. A qualitative thematic analysis was undertaken in Atlas.ti. to identify salient themes related to the shortage. Overall, participant accounts were rooted in a theme of desperation and uncertainty, with emphasis on six sub-themes: (1) withdrawal and strategies for alleviating withdrawal, including use of medical intervention and other detoxification attempts; (2) challenges of dealing with unpredictable drug availability, cost, and purity; (3) changes in drug use patterns, and actions taken to procure heroin and other drugs; (4) modifications in drug user relationship dynamics and networks, including introduction of risky group-level injection practices; (5) family and community response; and (6) new challenges with the heroin market resurgence. The heroin shortage led to a series of consequences for drug users, including increased risk of morbidity, mortality and disenfranchisement at social and structural levels. Availability of evidence-based services for drug users and emergency preparedness plans could have mitigated this impact. Published by Elsevier B.V.

Unidata's Vision for Providing Comprehensive and End-to-end Data Services

NASA Astrophysics Data System (ADS)

Ramamurthy, M. K.

2009-05-01

This paper presents Unidata's vision for providing comprehensive, well-integrated, and end-to-end data services for the geosciences. These include an array of functions for collecting, finding, and accessing data; data management tools for generating, cataloging, and exchanging metadata; and submitting or publishing, sharing, analyzing, visualizing, and integrating data. When this vision is realized, users no matter where they are or how they are connected to the Internetwill be able to find and access a plethora of geosciences data and use Unidata-provided tools and services both productively and creatively in their research and education. What that vision means for the Unidata community is elucidated by drawing a simple analogy. Most of users are familiar with Amazon and eBay e-commerce sites and content sharing sites like YouTube and Flickr. On the eBay marketplace, people can sell practically anything at any time and buyers can share their experience of purchasing a product or the reputation of a seller. Likewise, at Amazon, thousands of merchants sell their goods and millions of customers not only buy those goods, but provide a review or opinion of the products they buy and share their experiences as purchasers. Similarly, YouTube and Flickr are sites tailored to video- and photo-sharing, respectively, where users can upload their own content and share it with millions of other users, including family and friends. What all these sites, together with social-networking applications like MySpace and Facebook, have enabled is a sense of a virtual community in which users can search and browse products or content, comment and rate those products from anywhere, at any time, and via any Internet- enabled device like an iPhone, laptop, or a desktop computer. In essence, these enterprises have fundamentally altered people's buying modes and behavior toward purchases. Unidata believes that similar approaches, appropriately tailored to meet the needs of the scientific community, can be adopted to provide and share geosciences data and actively collaborate in the future. For example, future case-study data access systems, in addition to providing datasets and tools, will provide services that allow users to provide commentaries on a weather event, say a hurricane, as well as provide feedback on the quality, usefulness, and interpretation of the datasets through integrated blogs, forums, and Wikis, along with uploading and sharing products they derive, ancillary materials that users might have gathered (such as photos and videos from the storm), and publications and curricular materials they develop, all through a single data portal. In essence, such case study collections will be "living" or dynamic, allowing users to be also contributors as they add value to and grow existing case study collections.

African Americans are incarcerated at rates much higher than other racial and ethnic groups in the United States. We sought to qualitatively explore the relationships between ongoing involvement in the criminal justice system and continued drug use in a population of urban and rural African American cocaine users in a southern state. Semi-structured qualitative interviews were conducted among African American cocaine users in Arkansas between 2010 and 2012. Participants resided in both rural (two counties located in the eastern Arkansas Mississippi delta region) and urban (the county including the capital city of Little Rock) areas. Numerous important themes emerged from participants' narratives, including chronic involvement with the criminal justice system (being a "career criminal"), continued access to drugs while incarcerated, relapse, and reincarceration and lack of access to effective drug treatment. Conclusion/Importance: The themes which emerged from our data speak to the collective experience that many substance using populations in the United States face in dealing with the criminal justice system. Our findings highlight the need to better, more holistic ways of engaging African American substance users in community based substance use treatment and supportive services.

A Service Oriented Infrastructure for Earth Science exchange

Burnett, M.; Mitchell, A.

2008-12-01

NASA's Earth Science Distributed Information System (ESDIS) program has developed an infrastructure for the exchange of Earth Observation related resources. Fundamentally a platform for Service Oriented Architectures, ECHO provides standards-based interfaces based on the basic interactions for a SOA pattern: Publish, Find and Bind. This infrastructure enables the realization of the benefits of Service Oriented Architectures, namely the reduction of stove-piped systems, the opportunity for reuse and flexibility to meet dynamic business needs, on a global scale. ECHO is the result of the infusion of IT technologies, including those standards of Web Services and Service Oriented Architecture technologies. The infrastructure is based on standards and leverages registries for data, services, clients and applications. As an operational system, ECHO currently representing over 110 million Earth Observation resources from a wide number of provider organizations. These partner organizations each have a primary mission - serving a particular facet of the Earth Observation community. Through ECHO, those partners can serve the needs of not only their target portion of the community, but also enable a wider range of users to discover and leverage their data resources, thereby increasing the value of their offerings. The Earth Observation community benefits from this infrastructure because it provides a set of common mechanisms for the discovery and access to resources from a much wider range of data and service providers. ECHO enables innovative clients to be built for targeted user types and missions. There several examples of those clients already in process. Applications built on this infrastructure can include User-driven, GUI-clients (web-based or thick clients), analysis programs (as intermediate components of larger systems), models or decision support systems. This paper will provide insight into the development of ECHO, as technologies were evaluated for infusion, and a summary of how technologies where leveraged into a significant operational system for the Earth Observation community.

Data latency and the user community

NASA Astrophysics Data System (ADS)

Escobar, V. M.; Brown, M. E.; Carroll, M.

2013-12-01

The community using NASA Earth science observations in applications has grown significantly, with increasing sophistication to serve national interests. The National Research Council's Earth Science Decadal Survey report stated that the planning for applied and operational considerations in the missions should accompany the acquisition of new knowledge about Earth (NRC, 2007). This directive has made product applications at NASA an integral part of converting the data collected into actionable knowledge that can be used to inform policy. However, successfully bridging scientific research with operational decision making in different application areas requires looking into user data requirements and operational needs. This study was conducted to determine how users are incorporating NASA data into applications and operational processes. The approach included a review of published materials, direct interviews with mission representatives, and an online professional review, which was distributed to over 6000 individuals. We provide a complete description of the findings with definitions and explanations of what goes into measuring latency as well as how users and applications utilize NASA data products. We identified 3 classes of users: operational (need data in 3 hours or less), near real time (need data within a day of acquisition), and scientific users (need highest quality data, time independent). We also determined that most users with applications are interested in specific types of products that may come from multiple missions. These users will take the observations when they are available, however the observations may have additional applications value if they are available either by a certain time of day or within a period of time after acquisition. NASA has supported the need for access to low latency data on an ad-hoc basis and more substantively in stand-alone systems such as the MODIS Rapid Response system and more recently with LANCE. The increased level of support and advertising of that support has grown the community of individuals and organizations that use low-latency science data to supply decision making processes with updated information. These applications are increasingly high profile and have high societal value, which is of importance to NASA, the US Government and the broader society. The primary conclusions of this report revolve around clarifying NASA's intentions to support operations and near real time needs for quick access to data after acquisition. Specifically, clear statements from NASA Headquarters are needed to indicate the level of support that will be provided for low latency data products and whether that support should come directly from the missions or whether this support will come from separate stand-alone systems or direct broadcast. The results of the analysis clearly show the significant benefit to society for serving the needs of the agricultural, emergency response, environmental monitoring and weather communities who use low latency data today, and to grow the use of low latency NASA science data products into new communities in the future. These benefits can be achieved with a clear and consistent NASA policy on product latency.

Background It has been argued that quality improvements that result from user charges reduce their negative impact on utilization especially of the poor. In Uganda, because there was no concrete evidence for improvements in quality of care following the introduction of user charges, the government abolished user fees in all public health units on 1st March 2001. This gave us the opportunity to prospectively study how different aspects of quality of care change, as a country changes its health financing options from user charges to free services, in a developing country setting. The outcome of the study may then provide insights into policy actions to maintain quality of care following removal of user fees. Methods A population cohort and representative health facilities were studied longitudinally over 3 years after the abolition of user fees. Quantitative and qualitative methods were used to obtain data. Parameters evaluated in relation to quality of care included availability of drugs and supplies and; health worker variables. Results Different quality variables assessed showed that interventions that were put in place were able to maintain, or improve the technical quality of services. There were significant increases in utilization of services, average drug quantities and stock out days improved, and communities reported health workers to be hardworking, good and dedicated to their work to mention but a few. Communities were more appreciative of the services, though expectations were lower. However, health workers felt they were not adequately motivated given the increased workload. Conclusion The levels of technical quality of care attained in a system with user fees can be maintained, or even improved without the fees through adoption of basic, sustainable system modifications that are within the reach of developing countries. However, a trade-off between residual perceptions of reduced service quality, and the welfare gains from removal of user fees should guide such a policy change. PMID:18471297

Improving service user self-management: development and implementation of a strategy for the Richmond Response and Rehabilitation Team.

Sanders, Julie; Fitzpatrick, Joanne M

2017-01-01

Community rapid response and rehabilitation teams are used to prevent avoidable hospital admissions for adults living with multiple long-term conditions and to support early hospital discharge by providing short-term intensive multidisciplinary support. Supporting self-management is an important service intervention if desired outcomes are to be achieved. A Care Quality Commission inspection of the Richmond Response and Rehabilitation Team in 2014 identified that self-management plans were not routinely developed with service users and reported this as requiring improvement. This quality improvement project aimed to develop and implement a self-management strategy for service users and for 90% of service users to have a personalised self-management plan within 3 months. The quality improvement intervention used the Plan-Do-Study-Act model comprising: (1) the development of a self-management plan, (2) staff education to support service users to self-manage using motivational interviewing techniques, (3) piloting the self-management plan with service users, (4) implementation of the self-management plan and (5) monthly audit and feedback. Evaluation involved an audit of the number and quality of self-management plans developed with service users and a survey of staff knowledge and confidence to support service users to self-manage. Following implementation of the intervention, the number of self-management plans developed in collaboration with service users increased from 0 to 187 over a 4-week period. Monthly audit data confirmed that this improvement has been sustained. Results indicated that staff knowledge and confidence improved after an education intervention. Quality improvement methods facilitated development and operationalisation of a self-management strategy by a community rapid response and rehabilitation team. The next phase of the project is to evaluate the impact of the self-management strategy on key service outcomes including self-efficacy, unplanned and emergency hospital admissions and early discharges.

We examined the sociodemographic correlates of energy drink use and the differences between those who use them with and without alcohol in a representative community sample. A random-digit-dial landline telephone survey of adults in the Milwaukee, Wisconsin area responded to questions about energy drink and alcohol plus energy drink use. Almost one-third of respondents consumed at least one energy drink in their lifetime, while slightly over 25% used energy drinks in the past year and 6% were past-year alcohol plus energy drink users. There were important racial/ethnic differences in consumption patterns. Compared to non-users, past-year energy drink users were more likely to be non-Black minorities; and past-year alcohol plus energy drink users when compared to energy drink users only were more likely to be White and younger. Alcohol plus energy drink users also were more likely to be hazardous drinkers. Our results which are among the first from a community sample suggest a bifurcated pattern of energy drink use highlighting important population consumption differences between users of energy drinks only and those who use alcohol and energy drinks together.

Matsuo, Yutaka; Yasud, Yuki

Our purpose here is to (1) investigate the structure of the personal networks developed on mixi, a Japanese social networking service (SNS), and (2) to consider the governing mechanism which guides participants of a SNS to form an aggregate network. Our findings are as follows:the clustering coefficient of the network is as high as 0.33 while the characteristic path lenght is as low as 5.5. A network among central users (over 300 edges) consist of two cliques, which seems to be very fragile. Community-affiliation network suggests there are several easy-entry communities which later lead users to more high-entry, unique-theme communities. The analysis on connectedness within a community reveals the importance of real-world interaction. Lastly, we depict a probable image of the entire ecology on {\\\\em mixi} among users and communities, which contributes broadly to social systems on the Web.

Open Data, Jupyter Notebooks and Geospatial Data Standards Combined - Opening up large volumes of marine and climate data to other communities

Clements, O.; Siemen, S.; Wagemann, J.

2017-12-01

The EU-funded Earthserver-2 project aims to offer on-demand access to large volumes of environmental data (Earth Observation, Marine, Climate data and Planetary data) via the interface standard Web Coverage Service defined by the Open Geospatial Consortium. Providing access to data via OGC web services (e.g. WCS and WMS) has the potential to open up services to a wider audience, especially to users outside the respective communities. Especially WCS 2.0 with its processing extension Web Coverage Processing Service (WCPS) is highly beneficial to make large volumes accessible to non-expert communities. Users do not have to deal with custom community data formats, such as GRIB for the meteorological community, but can directly access the data in a format they are more familiar with, such as NetCDF, JSON or CSV. Data requests can further directly be integrated into custom processing routines and users are not required to download Gigabytes of data anymore. WCS supports trim (reduction of data extent) and slice (reduction of data dimension) operations on multi-dimensional data, providing users a very flexible on-demand access to the data. WCPS allows the user to craft queries to run on the data using a text-based query language, similar to SQL. These queries can be very powerful, e.g. condensing a three-dimensional data cube into its two-dimensional mean. However, the more processing-intensive the more complex the query. As part of the EarthServer-2 project, we developed a python library that helps users to generate complex WCPS queries with Python, a programming language they are more familiar with. The interactive presentation aims to give practical examples how users can benefit from two specific WCS services from the Marine and Climate community. Use-cases from the two communities will show different approaches to take advantage of a Web Coverage (Processing) Service. The entire content is available with Jupyter Notebooks, as they prove to be a highly beneficial tool to generate reproducible workflows for environmental data analysis.

This project was created to provide a National Community Solar Platform (NCSP) portal known as Community Solar Hub, that is available to any entity or individual who wants to develop community solar. This has been done by providing a comprehensive portal to make CEC’s solutions, and other proven community solar solutions, externally available for everyone to access – making the process easy through proven platforms to protect subscribers, developers and utilities. The successful completion of this project provides these tools via a web platform and integration APIs, a wide spectrum of community solar projects included in the platform, multiple groupsmore » of customers (utilities, EPCs, and advocates) using the platform to develop community solar, and open access to anyone interested in community solar. CEC’s Incubator project includes web-based informational resources, integrated systems for project information and billing systems, and engagement with customers and users by community solar experts. The combined effort externalizes much of Clean Energy Collective’s industry-leading expertise, allowing third parties to develop community solar without duplicating expensive start-up efforts. The availability of this platform creates community solar projects that are cheaper to build and cheaper to participate in, furthering the goals of DOE’s SunShot Initiative.

Community service contracting for older people in urban China: a case study in Guangdong Province.

PubMed

Lin, Wenyi

2016-01-01

Contracting of community services to non-governmental service-providing organisations - mainly social work agencies - is an emerging phenomenon and a social innovation with regard to delivering community services in urban China. Contracting of community services for the older person, which is the focus of this study, is embedded in the macro context of the development of social service contracting in China. Qualitative research techniques, including document analysis, case study, participant observation and in-depth interviews, were adopted for this study. Nine government officials, three staff working in Community Residents' Committees, 15 staff working in social work agencies and 41 older people were interviewed in an effort to understand the impact and challenges of community service contracting in urban China. The findings showed that the involvement of social work agencies in the community service provision system results in integration of community resources, expansion of service coverage and enhancement of older people's access to community services. However, several problems may impede the development of community service provision in the context of contracting in China. These include purchaser-oriented rather than user-oriented service provision, older people's negative attitude towards social work services, inappropriate performance measurement, reliance of non-government organisations on government funding and ambiguous definition of community services.

Similarity between community structures of different online social networks and its impact on underlying community detection

NASA Astrophysics Data System (ADS)

Fan, W.; Yeung, K. H.

2015-03-01

As social networking services are popular, many people may register in more than one online social network. In this paper we study a set of users who have accounts of three online social networks: namely Foursquare, Facebook and Twitter. Community structure of this set of users may be reflected in these three online social networks. Therefore, high correlation between these reflections and the underlying community structure may be observed. In this work, community structures are detected in all three online social networks. Also, we investigate the similarity level of community structures across different networks. It is found that they show strong correlation with each other. The similarity between different networks may be helpful to find a community structure close to the underlying one. To verify this, we propose a method to increase the weights of some connections in networks. With this method, new networks are generated to assist community detection. By doing this, value of modularity can be improved and the new community structure match network's natural structure better. In this paper we also show that the detected community structures of online social networks are correlated with users' locations which are identified on Foursquare. This information may also be useful for underlying community detection.

The GenABEL Project for statistical genomics.

2016-01-01

Development of free/libre open source software is usually done by a community of people with an interest in the tool. For scientific software, however, this is less often the case. Most scientific software is written by only a few authors, often a student working on a thesis. Once the paper describing the tool has been published, the tool is no longer developed further and is left to its own device. Here we describe the broad, multidisciplinary community we formed around a set of tools for statistical genomics. The GenABEL project for statistical omics actively promotes open interdisciplinary development of statistical methodology and its implementation in efficient and user-friendly software under an open source licence. The software tools developed withing the project collectively make up the GenABEL suite, which currently consists of eleven tools. The open framework of the project actively encourages involvement of the community in all stages, from formulation of methodological ideas to application of software to specific data sets. A web forum is used to channel user questions and discussions, further promoting the use of the GenABEL suite. Developer discussions take place on a dedicated mailing list, and development is further supported by robust development practices including use of public version control, code review and continuous integration. Use of this open science model attracts contributions from users and developers outside the "core team", facilitating agile statistical omics methodology development and fast dissemination.

In order to provide specifications for the automated Analytical Electrophoresis Facility (AAEF) that would satisfy the broadest variety of demands of a future user community, a survey was carried out of all those people who were identified as having published papers on cell electrophoresis in the past four years. A computer search was conducted of the relevant literature from which a list of 87 investigators was derived and defined as the user community for purposes of the mailing. A questionnaire was developed covering the areas of performance which required definition which was subsequently circulated to the user community. Based on the response to this survey performance specifications were assembled.

User-centered design to improve clinical decision support in primary care.

Brunner, Julian; Chuang, Emmeline; Goldzweig, Caroline; Cain, Cindy L; Sugar, Catherine; Yano, Elizabeth M

2017-08-01

A growing literature has demonstrated the ability of user-centered design to make clinical decision support systems more effective and easier to use. However, studies of user-centered design have rarely examined more than a handful of sites at a time, and have frequently neglected the implementation climate and organizational resources that influence clinical decision support. The inclusion of such factors was identified by a systematic review as "the most important improvement that can be made in health IT evaluations." (1) Identify the prevalence of four user-centered design practices at United States Veterans Affairs (VA) primary care clinics and assess the perceived utility of clinical decision support at those clinics; (2) Evaluate the association between those user-centered design practices and the perceived utility of clinical decision support. We analyzed clinic-level survey data collected in 2006-2007 from 170 VA primary care clinics. We examined four user-centered design practices: 1) pilot testing, 2) provider satisfaction assessment, 3) formal usability assessment, and 4) analysis of impact on performance improvement. We used a regression model to evaluate the association between user-centered design practices and the perceived utility of clinical decision support, while accounting for other important factors at those clinics, including implementation climate, available resources, and structural characteristics. We also examined associations separately at community-based clinics and at hospital-based clinics. User-centered design practices for clinical decision support varied across clinics: 74% conducted pilot testing, 62% conducted provider satisfaction assessment, 36% conducted a formal usability assessment, and 79% conducted an analysis of impact on performance improvement. Overall perceived utility of clinical decision support was high, with a mean rating of 4.17 (±.67) out of 5 on a composite measure. "Analysis of impact on performance improvement" was the only user-centered design practice significantly associated with perceived utility of clinical decision support, b=.47 (p<.001). This association was present in hospital-based clinics, b=.34 (p<.05), but was stronger at community-based clinics, b=.61 (p<.001). Our findings are highly supportive of the practice of analyzing the impact of clinical decision support on performance metrics. This was the most common user-centered design practice in our study, and was the practice associated with higher perceived utility of clinical decision support. This practice may be particularly helpful at community-based clinics, which are typically less connected to VA medical center resources. Published by Elsevier B.V.

Maintaining Quality and Confidence in Open-Source, Evolving Software: Lessons Learned with PFLOTRAN

Frederick, J. M.; Hammond, G. E.

2017-12-01

Software evolution in an open-source framework poses a major challenge to a geoscientific simulator, but when properly managed, the pay-off can be enormous for both the developers and the community at large. Developers must juggle implementing new scientific process models, adopting increasingly efficient numerical methods and programming paradigms, changing funding sources (or total lack of funding), while also ensuring that legacy code remains functional and reported bugs are fixed in a timely manner. With robust software engineering and a plan for long-term maintenance, a simulator can evolve over time incorporating and leveraging many advances in the computational and domain sciences. In this positive light, what practices in software engineering and code maintenance can be employed within open-source development to maximize the positive aspects of software evolution and community contributions while minimizing its negative side effects? This presentation will discusses steps taken in the development of PFLOTRAN (www.pflotran.org), an open source, massively parallel subsurface simulator for multiphase, multicomponent, and multiscale reactive flow and transport processes in porous media. As PFLOTRAN's user base and development team continues to grow, it has become increasingly important to implement strategies which ensure sustainable software development while maintaining software quality and community confidence. In this presentation, we will share our experiences and "lessons learned" within the context of our open-source development framework and community engagement efforts. Topics discussed will include how we've leveraged both standard software engineering principles, such as coding standards, version control, and automated testing, as well unique advantages of object-oriented design in process model coupling, to ensure software quality and confidence. We will also be prepared to discuss the major challenges faced by most open-source software teams, such as on-boarding new developers or one-time contributions, dealing with competitors or lookie-loos, and other downsides of complete transparency, as well as our approach to community engagement, including a user group email list, hosting short courses and workshops for new users, and maintaining a website.

Despite evidence supporting the ongoing provision of health education interventions in First Nations communities, there is a paucity of research that specifically addresses how these programs should be designed to ensure sustainability and long-term effects. Using a Community-Based Research approach, a collective case study was completed with three Canadian First Nations communities to address the following research question: What factors are related to sustainable health education programs, and how do they contribute to and/or inhibit program success in an Aboriginal context? Semi-structured interviews and a sharing circle were completed with 19 participants, including members of community leadership, external partners, and program staff and users. Seven factors were identified to either promote or inhibit program sustainability, including: 1) community uptake; 2) environmental factors; 3) stakeholder awareness and support; 4) presence of a champion; 5) availability of funding; 6) fit and flexibility; and 7) capacity and capacity building. Each factor is provided with a working definition, influential moderators, and key evaluation questions. This study is grounded in, and builds on existing research, and can be used by First Nations communities and universities to support effective sustainability planning for community-based health education interventions.

The Health Intervention Project: HIV risk reduction among African American women drug users.

PubMed Central

Sterk, Claire E.

2002-01-01

OBJECTIVE: This article describes the Health Intervention Project, an intervention for African American women in Atlanta, Georgia, who are crack cocaine users. METHODS:A formative phase involved ethnographic mapping of the physical and social infrastructure of the study communities and in-depth interviews with women crack cocaine users. Key findings that were incorporated into the intervention program included the exchange of sex for money or drugs, the women's experience with trauma and abuse, the role of men and male partners, the women's roles as mothers and members of extended families, their identity as African Americans, and their desire to reduce their risk for HIV/AIDS related to their drug use and sexual behavior. Individualized intervention sessions were designed to meet the women's needs. The motivation intervention emphasized self-motivation for behavioral change with the assistance of the interventionist, who facilitated the women's goal identification, action plan, and problem-solving skills. The negotiation intervention focused on improving technical and assertive communication skills. An action plan was developed, and the women worked on negotiation skills, self-control regarding sexual and drug-use encounters, assertiveness in sexual and drug-use interactions, and conflict resolution. CONCLUSION: Effective prevention and intervention programs must be framed within an appropriate racial, ethnic, and cultural context. Future research is needed to better understand risk in its social context, including the impact of community factors. PMID:12435832

It operates in 4 functions: Standard, Balance (raised on 2 rear wheels), 4 Wheel (for inclines, curbs, and uneven terrain), and Remote (for loading into a vehicle). The purpose of this study was to observe the IBOT at use in the home and in the community. Data were obtained via observations by trained clinicians, data recorded from a computerized data logger, and reports from each expert. Participants included 10 unimpaired nonwheelchair users (6 men, 4 women) and 4 expert wheelchair users (men with spinal cord injuries, T7-L1). The participants used the IBOT to perform a variety of activities, including holding eye-level discussions with colleagues and shopping by balancing on 2 wheels, going up and down steep ramps, traversing outdoor surfaces (eg, grass, dirt trails), and climbing curbs. The Balance and 4-Wheel functions were helpful and worked well. The IBOT required attention to control in the Standard function. The seat height was too high for most tables and desks, and the IBOT was challenging to use in the bathroom. The IBOT is a functional mobility device that expands the options of wheelchair users. It is most useful outdoors and where there is sufficient space to use its unique Balance function.

The purpose of the current study was to describe tuberculosis (TB) knowledge, beliefs, and experience with TB services among injecting drug users. Participants for this anonymous, cross-sectional study were recruited from a community based syringe exchange programme in Tallinn, Estonia. A structured questionnaire was completed and included information on socio-demographics, health history, drug use, and knowledge about TB and HIV. The study included 407 people (79% male, mean age 27.9 years, mean injection drug use 9.4 years). 32.9% of participants reported HIV infection and 1.7% lifetime history of TB. 26.4% participants (n=106) reported symptoms suggestive of TB. 93% of participants recognized correctly that TB is air-borne infection and 91% that HIV is a risk factor for TB. Only 40% of the participants knew that TB diagnostics and treatment in Estonia are free of charge for everybody and 58% reported they knew where to get health care services in case they suspected that they had TB. TB transmission and treatment adherence knowledge was better among those in contact with either health care or harm reduction services, e.g the community based syringe exchange programme. Similar to HIV services, TB prevention and education should be integrated into harm reduction and drug treatment programmes to facilitate early diagnosis and treatment of TB among injecting drug users.

This article describes the Health Intervention Project, an intervention for African American women in Atlanta, Georgia, who are crack cocaine users. A formative phase involved ethnographic mapping of the physical and social infrastructure of the study communities and in-depth interviews with women crack cocaine users. Key findings that were incorporated into the intervention program included the exchange of sex for money or drugs, the women's experience with trauma and abuse, the role of men and male partners, the women's roles as mothers and members of extended families, their identity as African Americans, and their desire to reduce their risk for HIV/AIDS related to their drug use and sexual behavior. Individualized intervention sessions were designed to meet the women's needs. The motivation intervention emphasized self-motivation for behavioral change with the assistance of the interventionist, who facilitated the women's goal identification, action plan, and problem-solving skills. The negotiation intervention focused on improving technical and assertive communication skills. An action plan was developed, and the women worked on negotiation skills, self-control regarding sexual and drug-use encounters, assertiveness in sexual and drug-use interactions, and conflict resolution. Effective prevention and intervention programs must be framed within an appropriate racial, ethnic, and cultural context. Future research is needed to better understand risk in its social context, including the impact of community factors.

For more than 20 years, the NASA Earth Observing System (EOS) has collected earth science data for thousands of scientific parameters now totaling nearly 15 Petabytes of data. In 2013, NASA's Global Imagery Browse Services (GIBS) formed its vision to "transform how end users interact and discover [EOS] data through visualizations." This vision included leveraging scientific and community best practices and standards to provide a scalable, compliant, and authoritative source for EOS earth science data visualizations. Since that time, GIBS has grown quickly and now services millions of daily requests for over 500 imagery layers representing hundreds of earth science parameters to a broad community of users. For many of these parameters, visualizations are available within hours of acquisition from the satellite. For others, visualizations are available for the entire mission of the satellite. The GIBS system is built upon the OnEarth and MRF open source software projects, which are provided by the GIBS team. This software facilitates standards-based access for compliance with existing GIS tools. The GIBS imagery layers are predominantly rasterized images represented in two-dimensional coordinate systems, though multiple projections are supported. The OnEarth software also supports the GIBS ingest pipeline to facilitate low latency updates to new or updated visualizations. This presentation will focus on the following topics: Overview of GIBS visualizations and user community Current benefits and limitations of the OnEarth and MRF software projects and related standards GIBS access methods and their in/compatibilities with existing GIS libraries and applications Considerations for visualization accuracy and understandability Future plans for more advanced visualization concepts including Vertical Profiles and Vector-Based Representations Future plans for Amazon Web Service support and deployments

The Partnership Network Knowledge Base (PNKB) is being developed to provide connectivity and deliver content for the research information needs of NASA's Applied Science Program and related scientific communities of practice. Data has been collected which will permit users to identify and analyze the current network of interactions between organizations within the community of practice, harvest research results fixed to those interactions, and identify potential collaborative opportunities to further research streams. The PNKB is being developed in parallel with the Research Projects Knowledge Base (RPKB) and will be deployed in a manner that is fully compatible and interoperable with the NASA enterprise architecture (EA). Information needs have been assessed through a survey of potential users, evaluations of existing NASA resource users, and collaboration between Stennis Space Center and The Mississippi Research Consortium (MRC). The PNKB will assemble information on funded research institutions and categorize the research emphasis of each as it relates to NASA's six major science focus areas and 12 national applications. The PNKB will include information about organizations that conduct NASA Earth Science research such as, principal investigators' affiliation, contact information, relationship-type with NASA and other NASA partners, funding arrangements, and formal agreements like memoranda-of-understanding. To further the utility of the PNKB, relational links have been integrated into the RPKB - which will contain data about projects awarded from NASA research solicitations, project investigator information, research publications, NASA data products employed, and model or decision support tools used or developed as well as new data product information. The combined PNKB and RPKB will be developed in a multi-tier architecture that will include a SQL Server relational database backend, middleware, and front end client interfaces for data entry.

Focus on service users' needs, coping and empowerment, user involvement, and comprehensiveness are supposed to be key elements of the Community Mental Health Centres in Norway. Taking a user-oriented approach means acknowledging the individual's own expectations, aims and hopes. However, studies that have investigated service users' expectations of treatment and support at Community Mental Health Centres are hard to find. The aim of the study was therefore to explore service users' expectations at the start of treatment at a Community Mental Health Centre. Within a collaborative framework, taking a hermeneutic-phenomenological approach, ten service users participated in in-depth interviews about their expectations, hopes and aims for treatment and recovery. The participants sought help due to various mental health issues that had interfered with their lives and created disability and suffering. A data-driven stepwise approach in line with thematic analysis was used. The study was approved by the Norwegian Social Science Data Services. The following four main themes representing participants' expectations at the start of treatment were elicited: hope for recovery, developing understanding, finding tools for coping and receiving counselling and practical assistance. Participants' expectations about treatment were tightly interwoven with their personal aims and hopes for their future life, and expectations were often related to practical and financial problems, the solution of which being deemed necessary to gain a safe basis for recovery in the long run. The transferability of the results may be limited by the small number of participants. The study emphasises how important it is that service users' personal aims and expectations guide the collaborative treatment process. In addition to providing treatment aimed at improving symptoms, Community Mental Health Centres should take a more comprehensive approach than today by providing more support with family issues, social life, education, work and financial issues. © 2016 Nordic College of Caring Science.

Forumclínic: the shaping of virtual communities to assist patients with chronic diseases.

Information and communication technologies (ICTs) provide new opportunities to complement traditional care while enhancing patient autonomy. With the objective to supplement patient care, a group of health professionals at the Hospital Clínic de Barcelona created Forumclínic, an online networking website in Spanish and Catalan. In 2008, seven web- and DVD-based chronic disease portals (Diabetes, Schizophrenia, Cardiac Ischemia, COPD, Depression, Breast Cancer and cardiovascular risk) were created with the following resources: multimedia patient education material; physician-specialist transcribed research (articles) news; an open question forum (for clinician-user and user-to-user interaction); and patient and specialist interview videos on the progress of disease, common diagnosis and treatment procedures; and information on the best or worst prognoses. Using data from Google Analytics, server logs were used to observe online behaviour patterns and user postings. This data combined with a mixed methods approach were used to evaluate the development of a virtual community (VC). A virtual community was developed when the number of forum visits was greater than those in the disease portal (definition). While nearly half of the visitors were from the Americas, the Schizophrenia, Breast Cancer, Depression and COPD forums met the criteria for and developed a virtual community. However, the Diabetes and Cardiac Ischemia forums did not reach VC status. It is also interesting to note that users in their late thirties and early forties were primarily women. The development of four virtual communities in Forumclínic seems to support the self-care needs of virtual patients. Users also reported appreciating the increased interaction with experts online and commonly collaborated with the forum moderator to guide and support other users with similar conditions in managing their health. Thence, we believe that Forumclínic is a good model to complement traditional patient care. A formal evaluation of this adjuvant form of care, from both the users' and moderators' perspective, is currently in its final stages.

This article is part of the study 'Illicit Drug Use in Seven Latin American Countries and Canada: Critical Perspectives of Family and Familiars' (7LACC), which investigated four domains: protective and risk factors; preventive initiatives; treatment facilities; and laws and policies. The article presents a section of the results based on four items of the laws and policies domain--as perceived by the family and acquaintances of illicit drug users living in the community. Participants were recruited in urban primary health care units located in Western Rio de Janeiro (city), Brazil. This multi-method, cross-temporal study performed interviews with 100 adults (18 years of age or older), all cognitively healthy. Results and key conclusions included non-compliance with the fundamental principles of the Unique Health System Legislation / Law 8.080/90 and the erroneous implementation of laws and public policies on illicit drug.

Analysis of satellite servicing cost benefits

NASA Technical Reports Server (NTRS)

Builteman, H. O.

1982-01-01

Under the auspices of NASA/JSC a methodology was developed to estimate the value of satellite servicing to the user community. Time and funding precluded the development of an exhaustive computer model; instead, the concept of Design Reference Missions was involved. In this approach, three space programs were analyzed for various levels of servicing. The programs selected fall into broad categories which include 80 to 90% of the missions planned between now and the end of the century. Of necessity, the extrapolation of the three program analyses to the user community as a whole depends on an average mission model and equivalency projections. The value of the estimated cost benefits based on this approach depends largely on how well the equivalency assumptions and the mission model match the real world. A careful definition of all assumptions permits the analysis to be extended to conditions beyond the scope of this study.

Hepatitis B vaccination for injection drug users--Pierce County, Washington, 2000.

PubMed

2001-05-18

Hepatitis B vaccination has been recommended for injection drug users (IDUs) since 1982, but vaccination coverage of IDUs remains low (1), and outbreaks of hepatitis B among IDUs continue to occur. An outbreak of hepatitis B primarily among IDUs in Pierce County, Washington, detected in April 2000, included 60 cases and resulted in three deaths among IDUs co-infected with hepatitis delta virus. A program to administer hepatitis B vaccine to IDUs was implemented to control the outbreak, and the number of cases identified decreased from 13 per month in May to two cases since November. This report describes a vaccination program during which IDUs accepted hepatitis B vaccination provided free of charge in community-based settings and illustrates how effective hepatitis B vaccination programs targeted at IDUs can be implemented through collaborations between departments of health and corrections and community organizations.

The study aims to evaluate an interprofessional community-based learning event, focussing on disability. The learning opportunity was based on the Leicester Model of Interprofessional Education, organised around the experiences and perceptions of service users and their carers. Programme participants were drawn from medicine and social work education in Leicester, UK, bringing together diverse traditions in the care of people with disabilities. Small student groups (3-4 students) worked from one of the eight community rehabilitation hospitals through a programme of contact with people with disabilities in hospital, at home or in other community settings. The evaluation, in March 2005, used a mixed methods approach, incorporating questionnaire surveys, focus group interviews with students and feedback from service users. Responses were collated and analysed using quantitative and qualitative measures. Fifty social work and 100 medical students completed the first combined delivery of the module. The findings indicated that the merging of social work and medical perspectives appear to create some tensions, although overall the student experience was found to be beneficial. Service users (16 responses) valued the process. They were not concerned at the prospect of meeting a number of students at home or elsewhere and were pleased to think of themselves as educators. Problems and obstacles still anticipated include changing the mindset of clinicians and practising social workers to enable them to support students from each other's disciplines in practice learning. The generally positive outcomes highlight that disability focussed joint learning offers a meaningful platform for interprofessional education in a practice environment.

Final report : PATTON Alliance gazetteer evaluation project.

2007-08-01

In 2005 the National Ground Intelligence Center (NGIC) proposed that the PATTON Alliance provide assistance in evaluating and obtaining the Integrated Gazetteer Database (IGDB), developed for the Naval Space Warfare Command Research group (SPAWAR) under Advance Research and Development Activity (ARDA) funds by MITRE Inc., fielded to the text-based search tool GeoLocator, currently in use by NGIC. We met with the developers of GeoLocator and identified their requirements for a better gazetteer. We then validated those requirements by reviewing the technical literature, meeting with other members of the intelligence community (IC), and talking with both the United States Geologic Surveymore » (USGS) and the National Geospatial Intelligence Agency (NGA), the authoritative sources for official geographic name information. We thus identified 12 high-level requirements from users and the broader intelligence community. The IGDB satisfies many of these requirements. We identified gaps and proposed ways of closing these gaps. Three important needs have not been addressed but are critical future needs for the broader intelligence community. These needs include standardization of gazetteer data, a web feature service for gazetteer information that is maintained by NGA and USGS but accessible to users, and a common forum that brings together IC stakeholders and federal agency representatives to provide input to these activities over the next several years. Establishing a robust gazetteer web feature service that is available to all IC users may go a long way toward resolving the gazetteer needs within the IC. Without a common forum to provide input and feedback, community adoption may take significantly longer than anticipated with resulting risks to the war fighter.« less

Financing geriatric programs in community health centers.

1991-01-01

There are approximately 600 Community and Migrant Health Centers (C/MHCs) providing preventive and primary health care services principally to medically underserved rural and urban areas across the United States. The need to develop geriatric programs within C/MHCs is clear. Less clear is how and under what circumstances a comprehensive geriatric program can be adequately financed. The Health Resources and Services Administration of the Public Health Service contracted with La Jolla Management Corporation and Duke University Center on Aging to identify successful techniques for obtaining funding by examining 10 "good practice" C/MHC geriatric programs. The results from this study indicated that effective techniques included using a variety of funding sources, maintaining accurate cost-per-user information, developing a marketing strategy and user incentives, collaborating with the area agency on aging and other community organizations, and developing special services for the elderly. Developing cost-per-user information allowed for identifying appropriate "drawing card" services, negotiating sound reimbursement rates and contracts with other providers, and assessing the financial impact of changing service mixes. A marketing strategy was used to enhance the ability of the centers to provide a comprehensive package of services. Collaboration with the area agency on aging and other community organizations and volunteers in the aging network was found to help establish referral networks and subsequently increase the number of elderly patients served. Finally, development of special services for the elderly, such as adult day care, case management, and health education, was found to increase program visibility, opportunities to work with the network of services for the aging, and clinical utilization.

Are ecstasy users biased toward endorsing somatic mental health symptoms? Results from a general community sample.

PubMed

George, Amanda M; Windsor, Tim D; Rodgers, Bryan

2011-04-01

Whether the reported poorer mental health of ecstasy users is due to a bias in endorsement of somatic symptoms has been postulated, but rarely examined. The purpose of this study is to investigate whether levels of ecstasy use were associated with differential probabilities of endorsing somatic mental health symptoms. Current ecstasy users aged 24-30 years (n = 316) were identified from a population-based Australian study. Measures included frequency of ecstasy, meth/amphetamine, and cannabis use and the Goldberg anxiety/depression symptom scales. Multiple indicator, multiple cause models demonstrated no bias towards endorsing somatic symptoms with higher ecstasy use, both with and without adjustment for gender, cannabis, and meth/amphetamine use. Other studies using alternate measures of mental health should adopt this approach to determine if there is a bias in the endorsement of somatic symptoms among ecstasy users.

In this paper, we present a method for predicting the value of virtual currencies used in virtual gaming environments that support multiple users, such as massively multiplayer online role-playing games (MMORPGs). Predicting virtual currency values in a virtual gaming environment has rarely been explored; it is difficult to apply real-world methods for predicting fluctuating currency values or shares to the virtual gaming world on account of differences in domains between the two worlds. To address this issue, we herein predict virtual currency value fluctuations by collecting user opinion data from a virtual community and analyzing user sentiments or emotions from the opinion data. The proposed method is straightforward and applicable to predicting virtual currencies as well as to gaming environments, including MMORPGs. We test the proposed method using large-scale MMORPGs and demonstrate that virtual currencies can be effectively and efficiently predicted with it.

2010-01-01

Since 1982. the Crustal Dynamics Data Information System (CDDIS) has supported the archive and distribution of geodetic data products acquired by the National Aeronautics and Space Administration (NASA) as well as national and international programs. The CDDIS provides easy, timely, and reliable access to a variety of data sets, products, and information about these data. These measurements. obtained from a global network of nearly 650 instruments at more than 400 distinct sites, include DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite), GNSS (Global Navigation Satellite System), SLR and LLR (Satellite and Lunar Laser Ranging), and VLBI (Very Long Baseline Interferometry). The CDDIS data system and its archive have become increasingly important to many national and international science communities, particularly several of the operational services within the International Association of Geodesy (IAG) and its observing system the Global Geodetic Observing System (GGOS), including the International DORIS Service (IDS), the International GNSS Service (IGS). the International Laser Ranging Service (ILRS), the International VLBI Service for Geodesy and Astrometry (IVS). and the International Earth rotation and Reference frame Service (IERS), Investigations resulting from the data and products available through the CDDIS support research in many aspects of Earth system science and global change. Each month, the CDDIS archives more than one million data and derived product files totaling over 90 Gbytes in volume. In turn. the global user community downloads nearly 1.2 TBytes (over 10.5 million files) of data and products from the CDDIS each month. The requirements of analysts have evolved since the start of the CDDIS; the specialized nature of the system accommodates the enhancements required to support diverse data sets and user needs. This paper discusses the CDDIS. including background information about the system and its. user communities. archive contents. available metadata, and future plans.

Integrated Medical Model Verification, Validation, and Credibility

The Integrated Medical Model (IMM) was designed to forecast relative changes for a specified set of crew health and mission success risk metrics by using a probabilistic (stochastic process) model based on historical data, cohort data, and subject matter expert opinion. A probabilistic approach is taken since exact (deterministic) results would not appropriately reflect the uncertainty in the IMM inputs. Once the IMM was conceptualized, a plan was needed to rigorously assess input information, framework and code, and output results of the IMM, and ensure that end user requests and requirements were considered during all stages of model development and implementation. METHODS: In 2008, the IMM team developed a comprehensive verification and validation (VV) plan, which specified internal and external review criteria encompassing 1) verification of data and IMM structure to ensure proper implementation of the IMM, 2) several validation techniques to confirm that the simulation capability of the IMM appropriately represents occurrences and consequences of medical conditions during space missions, and 3) credibility processes to develop user confidence in the information derived from the IMM. When the NASA-STD-7009 (7009) was published, the IMM team updated their verification, validation, and credibility (VVC) project plan to meet 7009 requirements and include 7009 tools in reporting VVC status of the IMM. RESULTS: IMM VVC updates are compiled recurrently and include 7009 Compliance and Credibility matrices, IMM VV Plan status, and a synopsis of any changes or updates to the IMM during the reporting period. Reporting tools have evolved over the lifetime of the IMM project to better communicate VVC status. This has included refining original 7009 methodology with augmentation from the NASA-STD-7009 Guidance Document. End user requests and requirements are being satisfied as evidenced by ISS Program acceptance of IMM risk forecasts, transition to an operational model and simulation tool, and completion of service requests from a broad end user consortium including Operations, Science and Technology Planning, and Exploration Planning. CONCLUSIONS: The VVC approach established by the IMM project of combining the IMM VV Plan with 7009 requirements is comprehensive and includes the involvement of end users at every stage in IMM evolution. Methods and techniques used to quantify the VVC status of the IMM have not only received approval from the local NASA community but have also garnered recognition by other federal agencies seeking to develop similar guidelines in the medical modeling community.

Novel Scientific Visualization Interfaces for Interactive Information Visualization and Sharing

Demir, I.; Krajewski, W. F.

2012-12-01

As geoscientists are confronted with increasingly massive datasets from environmental observations to simulations, one of the biggest challenges is having the right tools to gain scientific insight from the data and communicate the understanding to stakeholders. Recent developments in web technologies make it easy to manage, visualize and share large data sets with general public. Novel visualization techniques and dynamic user interfaces allow users to interact with data, and modify the parameters to create custom views of the data to gain insight from simulations and environmental observations. This requires developing new data models and intelligent knowledge discovery techniques to explore and extract information from complex computational simulations or large data repositories. Scientific visualization will be an increasingly important component to build comprehensive environmental information platforms. This presentation provides an overview of the trends and challenges in the field of scientific visualization, and demonstrates information visualization and communication tools in the Iowa Flood Information System (IFIS), developed within the light of these challenges. The IFIS is a web-based platform developed by the Iowa Flood Center (IFC) to provide access to and visualization of flood inundation maps, real-time flood conditions, flood forecasts both short-term and seasonal, and other flood-related data for communities in Iowa. The key element of the system's architecture is the notion of community. Locations of the communities, those near streams and rivers, define basin boundaries. The IFIS provides community-centric watershed and river characteristics, weather (rainfall) conditions, and streamflow data and visualization tools. Interactive interfaces allow access to inundation maps for different stage and return period values, and flooding scenarios with contributions from multiple rivers. Real-time and historical data of water levels, gauge heights, and rainfall conditions are available in the IFIS. 2D and 3D interactive visualizations in the IFIS make the data more understandable to general public. Users are able to filter data sources for their communities and selected rivers. The data and information on IFIS is also accessible through web services and mobile applications. The IFIS is optimized for various browsers and screen sizes to provide access through multiple platforms including tablets and mobile devices. Multiple view modes in the IFIS accommodate different user types from general public to researchers and decision makers by providing different level of tools and details. River view mode allows users to visualize data from multiple IFC bridge sensors and USGS stream gauges to follow flooding condition along a river. The IFIS will help communities make better-informed decisions on the occurrence of floods, and will alert communities in advance to help minimize damage of floods.

Abstract Objective  To systematically review feedback from pharmacy users on their perceptions and experiences of health‐related advice and services provided from community pharmacies. Methods  The focus of the review was community pharmacy activities in relation to promoting health and well‐being, preventing ill‐health and maintaining health. Searches were conducted for peer‐reviewed (international) and non‐peer‐reviewed (UK) research. Electronic databases searched included MEDLINE, EMBASE, Cochrane Library and International Pharmaceutical Abstracts; hand searches of key journals and conference abstracts, key informants. Key informants in the UK were contacted to identify unpublished studies. The inclusion period was 1990 onwards. Data extraction and synthesis  Data were abstracted into a matrix by one author with a sample checked by a second. The Health Development Agency's Evidence Base 2000 standards and the evidence categories used by the Department of Health in the National Service Frameworks were applied to each item. Main results  Seven peer reviewed papers and 13 non‐peer reviewed reports were identified for inclusion in the review. Consumer usage of pharmacies is almost universal with prescription supplies and purchase of over the counter medicines predominating. Evidence shows that not only is usage low for general health advice, but that pharmacists are perceived as ‘drugs experts’ rather than experts on health and illness. Emergency hormonal contraception and head lice management schemes have been well received. There is a need to consider privacy and confidentiality surrounding advice giving. Conclusions  Users of community pharmacy‐based health development initiatives express a high level of satisfaction. If community pharmacies are to be used to their full extent, then actions to extending the public's awareness and acceptance of the pharmacist's role in giving advice will be crucial. Further research will be needed to measure any change in premises development on the public's perception of the level of privacy in pharmacies. PMID:15327458

ESA has established a Planetary Science Archive User Group (PSA-UG), with the task of offering independent advice to ESA's Planetary Science Archive (e.g. Heather et al., 2013). The PSA-UG is an official and independent body that continuously evaluates services and tools provided by the PSA to the community of planetary data scientific users. The group has been tasked with the following top level objectives: a) Advise ESA on future development of the PSA. b) Act as a focus for the interests of the scientific community. c) Act as an advocate for the PSA. d) Monitor the PSA activities. Based on this, the PSA-UG will report through the official ESA channels. Disciplines and subjects represented by PSA-UG members include: Remote Sensing of both Atmosphere and Solid Surfaces, Magnetospheres, Plasmas, Radio Science and Auxilliary data. The composition of the group covers ESA missions populating the PSA both now and in the near future. The first members of the PSA-UG were selected in 2013 and will serve for 3 years, until 2016. The PSA-UG will address the community through workshops, conferences and the internet. Written recommendations will be made to the PSA coordinator, and an annual report on PSA and the PSA-UG activities will be sent to the Solar System Exploration Working Group (SSEWG). Any member of the community and planetary data user can get in touch with individual members of the PSA-UG or with the group as a whole via the contacts provided on the official PSA-UG web-page: http://archives.esac.esa.int/psa/psa-ug.

Big Earth observation data have been produced, archived and made available online, but discovering the right data in a manner that precisely and efficiently satisfies user needs presents a significant challenge to the Earth Science (ES) community. An emerging trend in information retrieval community is to utilize knowledge graphs to assist users in quickly finding desired information from across knowledge sources. This is particularly prevalent within the fields of social media and complex multimodal information processing to name but a few, however building a domain-specific knowledge graph is labour-intensive and hard to keep up-to-date. In this work, we update our progress on the Earth Science Knowledge Graph (ESKG) project; an ESIP-funded testbed project which provides an automatic approach to building a dynamic knowledge graph for ES to improve interdisciplinary data discovery by leveraging implicit, latent existing knowledge present within across several U.S Federal Agencies e.g. NASA, NOAA and USGS. ESKG strengthens ties between observations and user communities by: 1) developing a knowledge graph derived from various sources e.g. Web pages, Web Services, etc. via natural language processing and knowledge extraction techniques; 2) allowing users to traverse, explore, query, reason and navigate ES data via knowledge graph interaction. ESKG has the potential to revolutionize the way in which ES communities interact with ES data in the open world through the entity, spatial and temporal linkages and characteristics that make it up. This project enables the advancement of ESIP collaboration areas including both Discovery and Semantic Technologies by putting graph information right at our fingertips in an interactive, modern manner and reducing the efforts to constructing ontology. To demonstrate the ESKG concept, we will demonstrate use of our framework across NASA JPL's PO.DAAC, NOAA's Earth Observation Requirements Evaluation System (EORES) and various USGS systems.

2016-12-01

European Research Infrastructures (RI) are built using ESFRI process, which dictates the steps towards a common European RIs. Building each RI separately creates unnessary barriers towards service users (e.g. on differing standards) and is not effiicient in e.g. e-science tool or data system development. To answer these inter-RI issues, the European Commission has funded several large scale cluster projectsto bring these RIs together already in planning and development phases to develop common tools, standards and methodologies, as well as learn from the exisiting systems. ENVRIplus is the cluster project for the environmental RIs in Europe, and provides platform for common development and sharing within the RI community. The project is organized around different themes, each having several workpackages with specific tasks. Major themesof the ENVRIplus are: Technical innovation, including tasks such as RI technology transfer, new observation techniques, autonomous operation, etc.; Data for science, with tasks such as RI reference model development, data discovery and citation, data publication, processing, etc.; Access to RIs, with specific tasks on interdicplinary and transnational access to RI services, and common access governance; Societal relevance and understanding, tackling on ethical issues on RI operations and understanding on human-environmental system and citizen science approaches, among others; Knowledge transfer, particularly between the RIs, and with developing RI organizations, organizing training and staff exchange; and Communication and dissemination, working towards a common environmental RI community (ENVRI community platform), and creating an own advisory RI discussion board (BEERi), and disseminating the ENVRIplus products globally. Importantly, all ENVRIplus results are open to any users from any country. Also, collaboration with international RIs and user communities are crucial to the success of the ENVRI initiatives. Overall goal is to do science globally, to answer global and regional critical challenges. The presentation will not only present the project, its state after nearly 2 years of operation, but will alsop present ideas towards building international and even more interdiciplinary collaboration on research infrastructures and their users.

Large sample volume 5000 ton multi-anvil presses have contributed to the exploration of deep Earth and planetary interiors, synthesis of ultra-hard and other novel materials, and serve as a sample complement to pressure and temperature regimes already attainable by diamond anvil cell experiments. However, no such facility exists in the Western Hemisphere. We are establishing an open user facility for the entire research community, with the unique capability of a 5000 ton multi-anvil and deformation press, HERA (High pressure Experimental Research Apparatus), supported by a host of extant co-located experimental and analytical laboratories and research staff. We offer wide range of complementary and/or preparatory experimental options. Any required synthesis of materials or follow up experiments can be carried out controlled atmosphere furnaces, piston cylinders, multi-anvil, or experimental impact apparatus. Additionally, our division houses two machine shops that would facilitate any modification or custom work necessary for development of CETUS, one for general fabrication and one located specifically within our experimental facilities. We also have a general sample preparation laboratory, specifically for experimental samples, that allows users to quickly and easily prepare samples for ebeam analyses and more. Our focus as contract staff is on serving the scientific needs of our users and collaborators. We are seeking community expert input on multiple aspects of this facility, such as experimental assembly design, module modifications, immediate projects, and future innovation initiatives. We've built a cooperative network of 12 (and growing) collaborating institutions, including COMPRES. CETUS is a coordinated effort leveraging HERA with our extant experimental, analytical, and planetary process modelling instrumentation and expertise in order to create a comprehensive model of the origin and evolution of our solar system and beyond. We are looking to engage the community in how the CETUS facility can best serve your needs.

Objectives Increased rates of illicit drug inhalation are thought to expose opiate misusers (OMUs) to an enhanced risk of respiratory health problems. This pilot study aimed to determine the feasibility of undertaking respiratory screening of OMUs in a community clinic. Setting Single-centre UK community substance misuse clinic. Participants All clinic attendees receiving treatment for opiate misuse were eligible to participate. 36 participants (mean age=37) were recruited over a 5-week period. The sample included 26 males and 10 females. Outcome measures Spirometry without bronchodilation; health related quality of life EQ-5D-3L; Asthma Control Test; Mini Asthma Quality of Life; Clinical COPD Questionnaire and the Treatment Outcome Profile were used to assess the respiratory health of participants. Findings were discussed with staff and service users in 2 patient and public involvement events and feedback was analysed thematically. Results 34 participants reported that they had smoked heroin. 8 participants diagnosed with asthma, scored under 13 on the Asthma Control Test, suggesting poorly controlled asthma. Participants (n=28), without a diagnosis of asthma completed the Lung Function Questionnaire. Of these, 79% produced scores under 18, indicating symptoms associated with the development of chronic obstructive pulmonary disease. Spirometry showed 14% of all participants had forced expiratory volume in 1 s/forced vital capacity <0.7 (without bronchodilator), indicating potential obstructive lung disease. Feedback from service users and staff suggested a willingness and capacity to deliver respiratory health screening programmes. Insight towards the difficulties service users have in accessing services and the burden of respiratory health was also provided. Conclusions It is feasible to undertake respiratory health screening of OMUs in a community clinic. Larger screening studies are warranted to determine the prevalence of respiratory health problems in this population. Research regarding asthma medicines adherence and access to healthcare among OMUs is also required. PMID:27742632

Drug users and female sex workers are among the groups most vulnerable to HIV infection in Vietnam. To address the HIV epidemic within these communities, former drug users and sex workers established the first community-based organizations (CBOs) in 2009. The study provides a focused assessment of CBOs' expanding efforts to advocate for their members that identifies existing collaborations with Vietnamese government programs. This assessment explores the barriers to and facilitators of expansion in order to propose recommendations to improve the working relationship between CBOs and government programs. Thirty-two individuals from drug user and sex worker CBOs (n = 24) and relevant government programs (n = 8) participated in face-to-face interviews in Hanoi, Ho Chi Minh City, and Hai Phong. Coded interview transcripts were analyzed qualitatively concerning the purpose of CBOs, the interactions between CBOs and government programs, and the perceived barriers, facilitators, and feasibility of future CBO-government program collaborations. Services provided by the CBOs were considered to improve members' quality of life. The formation of coalitions among CBOs increased efficiency in meeting members' specific service needs, in addition to internal capacity building. Government field staff interacted with CBOs by providing CBOs with technical and legal support. CBOs and methadone maintenance treatment (MMT) clinics collaborated to help the clinics meet patient enrollment quotas and facilitate entry into treatment for CBO members. Barriers to CBO-government program collaboration included perceived conflicting missions on how to address drug use and sex work in the community, limited CBO-government program communication, CBO mistrust of the MMT system, and lack of legal status for CBOs. To reduce these barriers, we recommend (1) introduction of CBO consultative services at government healthcare centers, (2) enlistment of CBO outreach to ensure full access to the imminent scaled-up MMT program, and (3) establishment of standards by which CBOs can obtain legal status.

Benefits of using the visualization server approach are discussed. Some thoughts regarding desirable features for visualization server hardware architectures are also addressed. A brief discussion of the software environment is included. The paper concludes by summarizing certain observations which we have made regarding the implementation of such visualization environments.

European grid services for global earth science

NASA Astrophysics Data System (ADS)

Brewer, S.; Sipos, G.

2012-04-01

This presentation will provide an overview of the distributed computing services that the European Grid Infrastructure (EGI) offers to the Earth Sciences community and also explain the processes whereby Earth Science users can engage with the infrastructure. One of the main overarching goals for EGI over the coming year is to diversify its user-base. EGI therefore - through the National Grid Initiatives (NGIs) that provide the bulk of resources that make up the infrastructure - offers a number of routes whereby users, either individually or as communities, can make use of its services. At one level there are two approaches to working with EGI: either users can make use of existing resources and contribute to their evolution and configuration; or alternatively they can work with EGI, and hence the NGIs, to incorporate their own resources into the infrastructure to take advantage of EGI's monitoring, networking and managing services. Adopting this approach does not imply a loss of ownership of the resources. Both of these approaches are entirely applicable to the Earth Sciences community. The former because researchers within this field have been involved with EGI (and previously EGEE) as a Heavy User Community and the latter because they have very specific needs, such as incorporating HPC services into their workflows, and these will require multi-skilled interventions to fully provide such services. In addition to the technical support services that EGI has been offering for the last year or so - the applications database, the training marketplace and the Virtual Organisation services - there now exists a dynamic short-term project framework that can be utilised to establish and operate services for Earth Science users. During this talk we will present a summary of various on-going projects that will be of interest to Earth Science users with the intention that suggestions for future projects will emerge from the subsequent discussions: • The Federated Cloud Task Force is already providing a cloud infrastructure through a few committed NGIs. This is being made available to research communities participating in the Task Force and the long-term aim is to integrate these national clouds into a pan-European infrastructure for scientific communities. • The MPI group provides support for application developers to port and scale up parallel applications to the global European Grid Infrastructure. • A lively portal developer and provider community that is able to setup and operate custom, application and/or community specific portals for members of the Earth Science community to interact with EGI. • A project to assess the possibilities for federated identity management in EGI and the readiness of EGI member states for federated authentication and authorisation mechanisms. • Operating resources and user support services to process data with new types of services and infrastructures, such as desktop grids, map-reduce frameworks, GPU clusters.

Effects of a recovery management intervention on Chinese heroin users' community recovery through the mediation effect of enhanced service utilization.

2015-09-01

This study investigates whether a recovery management intervention (RMI) can improve the utilization of community drug treatment and wraparound services among heroin users in China and subsequently lead to positive recovery outcomes. Secondary analysis was conducted drawing data from a randomized controlled trial; 100 heroin users with no severe mental health problems were recruited in two Shanghai districts (Hongkou and Yangpu) upon their release from compulsory rehabilitation facilities. A latent variable modeling approach was utilized to test whether the RMI influences heroin users' perceived motivation and readiness for treatment, enhances treatment and wraparound service participation, and, in turn, predicts better recovery outcomes. Enrollment in drug treatment and other social service utilization increased significantly as a result of RMI rather than an individual drug user's motivation and readiness for treatment. Increased service utilization thus led to more positive individual recovery outcomes. In addition to this mediation effect through service utilization, the RMI also improved participants' community recovery directly. Findings suggest that better drug treatment enrollment, community service utilization and recovery outcomes can be potentially achieved among heroin users in China with carefully designed case management interventions. © The Author 2014.

Emotional competence and online game use in adolescents.

PubMed

Seo, Mia; Kang, Hee Sun; Chae, Sun-Mi

2012-12-01

The purpose of this study was to explore the relations between emotional competence and online game use in adolescents. This study is a cross-sectional descriptive survey using a convenience sample. The participants were 2199 adolescents in South Korea. Online game use and emotional competence including positive emotion, emotional expression, and emotional intelligence were measured. The study results indicated that emotional competence was negatively correlated with excessive online game use. All variables of emotional competence were significantly lower in high-risk users compared with general users. In addition, female adolescents were rated significantly higher in emotional competence among general users, but there were no significant gender differences among high-risk users. The results of our study imply that high-risk game users have lower levels of emotional intelligence than general users do. The results of this study suggest that emotion is an important factor to which practitioners in psychomedical fields and nursing should pay attention. Therefore, nurses in schools and communities should regularly screen the emotions of adolescents who habitually play online games and develop a program to enhance emotional competence associated with online games.

An Efficiency Comparison of Document Preparation Systems Used in Academic Research and Development

Knauff, Markus; Nejasmic, Jelica

2014-01-01

The choice of an efficient document preparation system is an important decision for any academic researcher. To assist the research community, we report a software usability study in which 40 researchers across different disciplines prepared scholarly texts with either Microsoft Word or LaTeX. The probe texts included simple continuous text, text with tables and subheadings, and complex text with several mathematical equations. We show that LaTeX users were slower than Word users, wrote less text in the same amount of time, and produced more typesetting, orthographical, grammatical, and formatting errors. On most measures, expert LaTeX users performed even worse than novice Word users. LaTeX users, however, more often report enjoying using their respective software. We conclude that even experienced LaTeX users may suffer a loss in productivity when LaTeX is used, relative to other document preparation systems. Individuals, institutions, and journals should carefully consider the ramifications of this finding when choosing document preparation strategies, or requiring them of authors. PMID:25526083

Public investment in community health centres (CHCs) has been increasing as a response to rapid urbanisation in China. The objectives of this study were: (1) to examine factors associated with CHC use among residents from a recently urbanised community in western China and (2) to describe satisfaction with CHC among users. Cross-sectional design. A community recently converted to urban status with a newly constructed CHC in Southwest China. A random sample of 2259 adults in the Hezuo community in Chengdu, China, completed the survey in 2013. Trained staff interviewed study participants in their homes using structured questionnaires. The survey included questions regarding sociodemographics, health status, access to and usage of healthcare, health behaviours and CHC use. The Andersen's behavioural model of health service use was used to guide multivariable logistic regression modelling in identifying predisposing, enabling and need factors associated with the likelihood of using CHC. Descriptive statistics were used to describe residents' satisfaction with the CHC. A total of 71.8% of the respondents reported using the CHC during the past year. Factors influencing adults' CHC use included: gender, marital status, education level and knowledge of one's blood pressure (predisposing factors); annual household per capita income and walking time to the CHC (enabling factors) and self-rated health as well as physical activities (need factors). CHC users reported modest satisfaction across various aspects of the CHC. Neighbourhood CHC in urban areas provides important services to these residents living in a recently urbanised community. All three categories of factors in the Andersen model help explain the likelihood of CHC use. There is much room for improvement in CHC to enhance customer satisfaction. Future research is needed to improve access to CHCs and promote their use in urbanised populations with low to modest education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2006-01-01

Autism diagnostic practices among school and clinical psychologists, particularly those using the Autism Diagnostic Observation Schedule (ADOS), were examined using national survey results (N = 132). School and clinical psychologists were similar in following the Best Practice Guidelines for screening, diagnosis and assessment, School psychologists were more likely to include a school or home observation and teacher report than clinical psychologists but evaluated significantly fewer children with autism spectrum disorders per year compared to clinical psychologists. School psychologists who were ADOS users were more likely to consider themselves autism experts and include a review of records than ADOS non-users. Perceived advantages of the ADOS included its strength in capturing ASD-specific behaviors and the standardized structure provided for observation, while diagnostic discrimination and required resources were the most commonly identified disadvantages.

Incorporating profile information in community detection for online social networks

NASA Astrophysics Data System (ADS)

Fan, W.; Yeung, K. H.

2014-07-01

Community structure is an important feature in the study of complex networks. It is because nodes of the same community may have similar properties. In this paper we extend two popular community detection methods to partition online social networks. In our extended methods, the profile information of users is used for partitioning. We apply the extended methods in several sample networks of Facebook. Compared with the original methods, the community structures we obtain have higher modularity. Our results indicate that users' profile information is consistent with the community structure of their friendship network to some extent. To the best of our knowledge, this paper is the first to discuss how profile information can be used to improve community detection in online social networks.

This paper explores community structural factors in different low-income communities in the San Salvador, El Salvador that account for differences in the social context in which crack is used and in the HIV risk behaviors among crack users. Results suggest that both more distal (type of low-income community, level of violent crime and poverty) and proximate structural factors (type of site where drugs are used, and whether drugs are used within or outside of community of residence) influence HIV risk behaviors among drug users. Additionally, our results suggest that community structural factors influence the historical and geographic variation in drug use sites. PMID:22217125

2016-12-01

A major limitation to planning for weather and climate extremes is the lack of maintained and readily available tools that can provide robust and well-communicated predictions and advice on their impacts. The National Center for Atmospheric Research is facilitating a collaborative international program to develop and support such tools within its Capacity Center for Climate and Weather Extremes aimed at improving community resilience planning and reducing weather and climate impacts. A Global Risk, Resilience and Impacts Toolbox is in development and will provide: A portable web-based interface to process work requests from a variety of users and locations; A sophisticated framework that enables specialized community tools to access a comprehensive database (public and private) of geo-located hazard, vulnerability, exposure, and loss data; A community development toolkit that enables and encourages community tool developments geared towards specific user man­agement and planning needs, and A comprehensive community sup­port facilitated by NCAR utilizing tutorials and a help desk. A number of applications are in development, built off the latest climate science, and in collaboration with private industry and local and state governments. Example applications will be described, including a hurricane damage tool in collaboration with the reinsurance sector, and a weather management tool for the construction industry. These examples will serve as starting points to discuss the broader potential of the toolbox.

Mental health service users are at high risk of domestic violence but this is often not detected by mental health services. To explore the facilitators and barriers to disclosure of domestic violence from a service user and professional perspective. A qualitative study in a socioeconomically deprived south London borough, UK, with 18 mental health service users and 20 mental health professionals. Purposive sampling of community mental health service users and mental healthcare professionals was used to recruit participants for individual interviews. Thematic analysis was used to determine dominant and subthemes. These were transformed into conceptual maps with accompanying illustrative quotations. Service users described barriers to disclosure of domestic violence to professionals including: fear of the consequences, including fear of Social Services involvement and consequent child protection proceedings, fear that disclosure would not be believed, and fear that disclosure would lead to further violence; the hidden nature of the violence; actions of the perpetrator; and feelings of shame. The main themes for professionals concerned role boundaries, competency and confidence. Service users and professionals reported that the medical diagnostic and treatment model with its emphasis on symptoms could act as a barrier to enquiry and disclosure. Both groups reported that enquiry and disclosure were facilitated by a supportive and trusting relationship between the individual and professional. Mental health services are not currently conducive to the disclosure of domestic violence. Training of professionals in how to address domestic violence to increase their confidence and expertise is recommended.

To identify predictors of frequent attenders (HF) in Primary Health Care (PHC) centres in a sample of frequent attenders (HF) in Emergency Departments (ED). This was an observational, retrospective, multicentre cohort study. The HF patients were selected from patients seen in the ED between January 1 and December 31, 2013. Setting Patients were recruited from 17 public hospitals of the Community of Madrid, Spain. Variables on the index visit to the ED were collected. The sample was analysed in terms of being or not being an HF user in PHC. An HF user is considered a patient who made at least 10 visits in each level of care for a year. A total of 1284 HF patients were included. An analysis was performed on 423 (32.9%) HF users in ED with 16 (12-25) visits to PHC vs. 861 (67.1%) non-HF users in ED, with 4 (2-6) visits to PHC. Independent predictors of HF in PHC: over 65 years (OR: 1.51; 95% CI: 1.07-2.13; P=.019), cognitive impairment (OR: 1.63; 95% CI: 1.01-2.65; P=.049), taking >3 drugs (OR: 1.56; 95% CI: 1.06-2.30; P=.025), and living in the community vs. nursing home or homeless (OR: 3.05; 95% CI: 1.14-8.16; P=.026). Among HF patients in the ED, the fact that of being over 65 years, taking 3or more drugs, suffering cognitive impairment, and living in the community, are also considered to be predictors of HF in PHC.

A number of developing countries have contracted out public health facilities to the Non-Government Organizations (NGOs) in order to improve service utilization. However, there is a paucity of in-depth qualitative information on barriers to access services as a result of contracting from service users' perspective. The objective of this study was to explore perceived barriers to utilizing Maternal and Neonatal Health (MNH) services, in health facilities contracted out by government to NGO for service provision versus in those which are managed by government (non-contracted). A community-based qualitative exploratory study was conducted between April to September 2012 at two contracted-out and four matched non-contracted primary healthcare facilities in Thatta and Chitral, rural districts of Pakistan. Using semi-structured guide, the data were collected through thirty-six Focus Group Discussions (FGDs) conducted with mothers and their spouses in the catchment areas of selected facilities. Thematic analysis was performed using NVivo version 10.0 in which themes and sub-themes emerged. Key barriers reported in contracted sites included physical distance, user charges and familial influences. Whereas, poor functionality of health centres was the main barrier for non-contracted sites with other issues being comparatively less salient. Decision-making patterns for participants of both catchments were largely similar. Spouses and mother-in-laws particularly influenced the decision to utilize health facilities. Contracting out of health facility reduces supply side barriers to MNH services for the community served but distance, user charges and low awareness remain significant barriers. Contracting needs to be accompanied by measures for transportation in remote settings, oversight on user fee charges by contractor, and strong community-based behavior change strategies. © 2015 by Kerman University of Medical Sciences.

Toolsets for Airborne Data (TAD): Enhanced Airborne Data Merging Functionality through Spatial and Temporal Subsetting

NASA Astrophysics Data System (ADS)

Early, A. B.; Chen, G.; Beach, A. L., III; Northup, E. A.

2016-12-01

NASA has conducted airborne tropospheric chemistry studies for over three decades. These field campaigns have generated a great wealth of observations, including a wide range of the trace gases and aerosol properties. The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in Hampton Virginia originally developed the Toolsets for Airborne Data (TAD) web application in September 2013 to meet the user community needs for manipulating aircraft data for scientific research on climate change and air quality relevant issues. The analysis of airborne data typically requires data subsetting, which can be challenging and resource intensive for end users. In an effort to streamline this process, the TAD toolset enhancements will include new data subsetting features and updates to the current database model. These will include two subsetters: temporal and spatial, and vertical profile. The temporal and spatial subsetter will allow users to both focus on data from a specific location and/or time period. The vertical profile subsetter will retrieve data collected during an individual aircraft ascent or descent spiral. This effort will allow for the automation of the typically labor-intensive manual data subsetting process, which will provide users with data tailored to their specific research interests. The development of these enhancements will be discussed in this presentation.

The appropriate utilization of community services by people with mental health difficulties is becoming increasingly important in Japan. The aim of the present study was to describe service needs, as perceived by people with mental health difficulties living in the community and their service providers. We analyzed the difference between two necessity ratings using paired data in order to determine implications related to needs assessment for mental health services. This cross-sectional study used two self-reported questionnaires, with one questionnaire administered to mental health service users living in the community and another questionnaire to staff members providing services to those users at community service facilities. The study was conducted in psychiatric social rehabilitation facilities for people with mental health difficulties in Japan. The paired client and staff responses rated needs for each kind of mental health and social service independently. The 19 services listed in the questionnaire included counseling and healthcare, housing, renting, daily living, and employment. Overall, 246 individuals with mental health difficulties were asked to participate in this study, and after excluding invalid responses, 188 client-staff response dyads (76.4% of recruited people, 83.6% of people who gave consent) were analyzed in this study. A Wilcoxon matched-pairs signed rank test was used to compare the perceived needs, and weighted and unweighted Kappa statistics were calculated to assess rating agreement within client-staff dyads. Over 75% of participants in our study, who were people with mental health difficulties living in the community, regarded each type of mental health service as "somewhat necessary," or "absolutely necessary" to live in their community. Most clients and staff rated healthcare facilities with 24/7 crisis consultation services as necessary. Agreement between client and staff ratings of perceived needs for services was low (Kappa = .02 to .26). Services regarding housing, renting a place to live, and advocacy had the same tendency in that clients perceived a higher need when compared to staff perceptions (p < .01). It is essential for the service providers to identify the services that each user needs, engage in dialogue, and involve clients in service planning and development.

Co-designing communication and hazard preparedness strategies at Turrialba volcano, Costa Rica

NASA Astrophysics Data System (ADS)

van Manen, Saskia; Avard, Geoffroy; Martinez, Maria

2014-05-01

Globally volcanic activity results in huge human, social, environmental and economic losses. Disaster risk reduction (DRR) is the concept and systematic practice of reducing disaster risks and associated losses through a wide range of strategies, including efforts to increase knowledge through education and outreach. However, recent studies have shown a substantial gap between risk reduction actions taken at national and local levels, with national policies showing little change at the community level. Yet it is at local levels are where DRR efforts can have the biggest impact. This research focuses on communicating hazard preparedness strategies at Turrialba volcano, Costa Rica. Located in the Central Cordillera just 35 km northeast of Costa Rica's capital city San Jose this 3,340 m high active stratovolcano looms over Costa Rica's Central Valley, the social and economic hub of the country. Following progressive increases in degassing and seismic activity Turrialba resumed activity in 1996 after more than 100 years of quiescence. Since 2007 it has continuously emitted gas and since 2010 intermittent phreatic explosions accompanied by ash emissions have occurred. Despite high levels of hazard salience individuals and communities are not or under-prepared to deal with a volcanic eruption. In light of Turrialba's continued activity engaging local communities with disaster risk management is key. At the local levels culture (collective behaviours, interactions, cognitive constructs, and affective understanding) is an important factor in shaping peoples' views, understanding and response to natural phenomena. As such an increasing number of academic studies and intergovernmental organisations advocate for the incorporation of cultural context into disaster risk reduction strategies, which firstly requires documenting people's perception. Therefore approaching community disaster preparedness from a user-centred perspective, through an iterative and collaborative approach, is likely to result in DRR strategies that are considered more applicable and user-friendly by end users. This work presents results of a disaster preparedness workshop held with local communities around Turrialba. The workshop engaged the community in ideation and designing of concepts to increase levels of hazard preparedness. The concepts resulting from the workshop will be used to develop, through further collaboration with the end-users, DRR strategies tailored to be more relevant and accessible to the public. The approach presented here can equally be applied to the communication of DRR strategies in relation to other (natural) hazards.

2017-12-01

For the last three years, a new ESA Data User Element (DUE) project had focussed on creating improved knowledge about the Essential Climate Variable Biomass. The main purpose of the DUE GlobBiomass project is to better characterize and to reduce uncertainties of AGB estimates by developing an innovative synergistic mapping approach in five regional sites (Sweden, Poland, Mexico, Kalimantan, South Africa) for the epochs 2005, 2010 and 2015 and for one global map for the year 2010. The project team includes leading Earth Observation experts of Europe and is linked through Partnership Agreements with further national bodies from Brazil, Canada, China, Russia and South Africa. GlobBiomass has demonstrated how EO observation data can be integrated with in situ measurements and ecological understanding to provide improved biomass estimates that can be effectively exploited by users. The target users had mainly be drawn from the climate and carbon cycle modelling communities and included users concerned with carbon emissions and uptake due to biomass changes within initiatives such as REDD+. GlobBiomass provided a harmonised structure that can be exploited to address user needs for biomass information, but will be capable of being progressively refined as new data and methods become available. This presentation will give an overview of the technical prerequisites and final results of the GlobBiomass project.

Wiki use in mental health practice: recognizing potential use of collaborative technology.

Web 2.0, the second-generation of the World Wide Web, differs to earlier versions of Web development and design in that it facilitates more user-friendly, interactive information sharing and mechanisms for greater collaboration between users. Examples of Web 2.0 include Web-based communities, hosted services, social networking sites, video sharing sites, blogs, mashups, and wikis. Users are able to interact with others across the world or to add to or change website content. This paper examines examples of wiki use in the Australian mental health sector. A wiki can be described as an online collaborative and interactive database that can be easily edited by users. They are accessed via a standard Web browser which has an interface similar to traditional Web pages, thus do not require special application or software for the user. Although there is a paucity of literature describing wiki use in mental health, other industries have developed uses, including a repository of knowledge, a platform for collaborative writing, a project management tool, and an alternative to traditional Web pages or Intranets. This paper discusses the application of wikis in other industries and offers suggestions by way of examples of how this technology could be used in the mental health sector.

The SeaWiFS Data Analysis System (SeaDAS) is a comprehensive software package for the processing, display, and analysis of ocean data from a variety of satellite sensors. Continuous development and user support by programmers and scientists for more than a decade has helped to make SeaDAS the most widely used software package in the world for ocean color applications, with a growing base of users from the land and sea surface temperature community. Full processing support for past (CZCS, OCTS, MOS) and present (SeaWiFS, MODIS) sensors, and anticipated support for future missions such as NPP/VIIRS, enables end users to reproduce the standard ocean archive product suite distributed by NASA's Ocean Biology Processing Group (OBPG), as well as a variety of evaluation and intermediate ocean, land, and atmospheric products. Availability of the processing algorithm source codes and a software build environment also provide users with the tools to implement custom algorithms. Recent SeaDAS enhancements include synchronization of MODIS processing with the latest code and calibration updates from the MODIS Calibration Support Team (MCST), support for all levels of MODIS processing including Direct Broadcast, a port to the Macintosh OS X operating system, release of the display/analysis-only SeaDAS-Lite, and an extremely active web-based user support forum.

While recreational cannabis use is common, medical cannabis programs have proliferated across North America, including a federal program in Canada. Few comparisons of medical and recreational cannabis users (RCUs) exist; this study compared these groups on key characteristics. Data came from a community-recruited sample of formally approved medical cannabis users (MCUs; n = 53), and a sub-sample of recreational cannabis users (RCUs; n = 169) from a representative adult survey in Ontario (Canada). Samples were telephone-surveyed on identical measures, including select socio-demographic, substance and medication use, and health and disability measures. Based on initial bivariate comparisons, multivariate logistical regression with a progressive adjustment approach was performed to assess independent predictors of group status. In bivariate analyses, older age, lower household income, lower alcohol use, higher cocaine, prescription opioid, depression and anxiety medication use, and lower health and disability status were significantly associated with medical cannabis use. In the multivariate analysis, final model, household income, alcohol use, and disability levels were associated with medical cannabis use. Conclusions/Scientific Significance: Compared to RCUs, medical users appear to be mainly characterized by factors negatively influencing their overall health status. Future studies should investigate the actual impact and net benefits of medical cannabis use on these health problems. © 2017 S. Karger AG, Basel.

Determinants of compliance with nasal continuous positive airway pressure treatment applied in a community setting.

PubMed

Ball, E M.; Banks, M B.

2001-05-01

Objectives: To assess determinants of nasal continuous positive airway pressure (CPAP) compliance when applied in a community setting.Background: One-third of obstructive sleep apnea patients eventually refuse CPAP therapy. Treatment outcomes may be improved by identifying predictors of CPAP failure, including whether management by primary care physicians without sleep consultation affects results.Methods: Polysomnogram, chart review, and questionnaire results for regular CPAP users (n=123) were compared with those returning the CPAP machine (n=26).Results: Polysomnographic data and the presence of multiple sleep disorders were only modestly predictive of CPAP compliance. Striking differences in questionnaire responses separated CPAP users from non-users, who reported less satisfaction with all phases of their diagnosis and management. Rates of CPAP use were not significantly different between patients managed solely by their primary care physician or by a sleep consultant.Conclusions: Polysomnographic findings are unlikely to identify eventual CPAP non-compliers in a cost-effective fashion. Improvements in sleep apnea management may result from addressing the role of personality factors and multiple sleep disorders in determining compliance. In this practice setting, management by primary care physicians did not significantly degrade CPAP compliance.

Developing Toolsets for AirBorne Data (TAD): Overview of Design Concept

NASA Astrophysics Data System (ADS)

2013-12-01

NASA has conducted airborne tropospheric chemistry studies for about three decades. These field campaigns have generated a great wealth of observations, including a wide range of the trace gases and aerosol properties. Even though the spatial and temporal coverage is limited, the aircraft data offer high resolution and comprehensive simultaneous coverage of many variables, e.g. ozone precursors, intermediate photochemical species, and photochemical products. The recent NASA Earth Venture Program has generated an unprecedented amount of aircraft observations in terms of the sheer number of measurements and data volume. The ASDC Toolset for Airborne Data (TAD) is being designed to meet the user community needs for aircraft data for scientific research on climate change and air quality relevant issues, particularly: 1) Provide timely access to a broad user community, 2) Provide an intuitive user interface to facilitate quick discovery of the variables and data, 3) Provide data products and tools to facilitate model assessment activities, e.g., merge files and data subsetting capabilities, 4) Provide simple utility 'calculators', e.g., unit conversion and aerosol size distribution processing, and 5) Provide Web Coverage Service capable tools to enhance the data usability. The general strategy and design of TAD will be presented.

Voting advice applications (VAAs) are online tools that have become increasingly popular and purportedly aid users in deciding which party/candidate to vote for during an election. In this paper we present an innovation to current VAA design which is based on the introduction of a social network element. We refer to this new type of online tool as a social voting advice application (SVAA). SVAAs extend VAAs by providing (a) community-based recommendations, (b) comparison of users' political opinions, and (c) a channel of user communication. In addition, SVAAs enriched with data mining modules, can operate as citizen sensors recording the sentiment of the electorate on issues and candidates. Drawing on VAA datasets generated by the Preference Matcher research consortium, we evaluate the results of the first VAA-Choose4Greece-which incorporated social voting features and was launched during the landmark Greek national elections of 2012. We demonstrate how an SVAA can provide community based features and, at the same time, serve as a citizen sensor. Evaluation of the proposed techniques is realized on a series of datasets collected from various VAAs, including Choose4Greece. The collection is made available online in order to promote research in the field.

2005-12-01

The goal of the GES-DISC Interactive Online Visualization and Analysis System (Giovanni) is to provide earth science users a means for performing data analysis on data in the Goddard Earth Sciences (GES) Distributed Active Archive Center (DAAC) without having to download the data. Through Giovanni, users are able to apply statistical analysis on many individual gridded global data products across multiple instruments and even inter-compare parameters from more than one instrument. Giovanni currently allows users to select a time window and a region of interest to generate many graphical output types including area plots (time-averaged), time-series (area-averaged), Hovmoller (latitude vs. time, longitude vs. time), and animations for area plots. A number of graphical output types are also available for parameter inter-comparisons. ASCII output is also available for those who want to apply their own analysis software. Using the knowledge gained from Giovanni, a user can minimize the amount of data they need to download while maximizing the amount of relevant content in those data. The design challenges of Giovanni are (1) to successfully balance a simple, intuitive Web interface with the complexity and heterogeneity of our data, (2) to have a simple and flexible configuration so that new data sets and parameters can be added and organized for particular user communities, (3) to be agnostic with respect to the analysis software and graphing software and, (4) scalability. In a short time, the original Giovanni (Giovanni 1) has grown from two instances to eight (Giovanni 2), each tailored for a specific user community. The demand, however, for Giovanni and its capabilities continues to increase and in order to meet those demands, a redesign effort of Giovanni, which we call Giovanni 3, is being undertaken.

Sowers, Wesley; Marin, Robert

2014-01-01

Transforming the mental health system into a recovery oriented, integrated system of care requires a psychiatric work force that understands the relationship between recovery processes and community living. Fellowship programs in public and community psychiatry contribute to this transformation by educating psychiatrists about recovery, system dynamics, leadership, effective administration and community involvement. This paper describes a novel approach to fellowship programming that accomplishes these aims through an organizational strategy that emphasizes community engagement. After describing the administrative background for the program, we describe how the content curriculum and teaching process focus on the engagement of community members-both service users and service providers-as participating faculty. The faculty includes over 100 consumers, family members, advocacy group representatives, clinicians, and administrators. We present evaluation data obtained from 45 of the 100 community and university faculty who participated in the first 2 years' of the fellowship and conclude with a critique and recommendations for further progress in community engaged fellowship training.

Community-university partnerships can lend themselves to the development of tools that encourage and promote future community health development. The electronic manual, "Building Farmacies," describes an approach for developing capacity and sustaining a community health center-based farmers' market that emerged through a community-university partnership. Manual development was guided by the Knowledge to Action Framework and experiences developing a multivendor, produce-only farmers' market at a community health center in rural South Carolina. The manual was created to illustrate an innovative solution for community health development. The manual was disseminated electronically through 25 listservs and interested individuals voluntarily completed a Web-based survey to access the free manual. During the 6-month dissemination period, 271 individuals downloaded the manual. Findings highlighted the value of translating community-based participatory research into user-friendly manuals to guide future intervention development and dissemination approaches, and demonstrate the need to include capacity building opportunities to support translation and adoption of interventions. © 2015 Wiley Periodicals, Inc.

Prison, a missing target to address issues related to drug detoxification and rehabilitation: Nepalese experiences.

PubMed

Kant Jha, Chandra; M Donovan, Dennis

2013-01-01

Drug use has numerous consequences on health, the economy, culture and the peace and security of families and communities. Drug users often engage in various criminal activities, including drug dealing, to sustain their drug use. Under Nepalese law, consumption, possession and sale of drugs are illegal, which increases the risk of incarceration for drug users. Using a phenomenological/qualitative approach, the paper explores how various activities can lead to the arrest of drug users, how they cope without taking drugs in custody and prison and how they plan abstinence after release. Participants engaged in various categories of criminal activity, including stealing, looting, etc. Most of the drug users were in custody and prison at least once. Drug use relapses led the participants to re-engage in criminal activities including drug dealing. Parents were often overburdened by their sons and daughter's drug use and were worried about their repeated relapses. Finally, some parents negotiated with their sons and daughters to keep them in prison where they would be able to stay without taking drugs and their involvement in crimes and conflicts would decrease. Keeping substance abusers in prison does not appear to be an effective strategy, as many participants relapse after release from prison. However, a prison-based educational and health promotion strategy would be beneficial for drug users to develop knowledge and skills on staying drug-free. However, to date, no effort has been made to provide such services to drug users and develop their coping strategy after release.

Illicit drug users account for the majority of cases of HCV infection in the developed world, but few have received treatment. We evaluated barriers to initiating HCV treatment -- including general treatment willingness -- and factors associated with these among HCV infected illicit drug users. Participants were recruited via convenience sampling from two community clinics in Canada. Individuals age >18 years with a history of illicit drug use completed interviewer-administered surveys. Those reporting positive HCV testing underwent additional questioning on willingness, uptake and barriers to treatment for HCV. Of 188 HCV positive illicit drug users, 16% (n=30) had received treatment for HCV. Factors associated with a decreased treatment uptake included current heroin use and HIV/HCV co-infection. Among those not having received therapy, 77% (117/153) indicated a willingness to receive HCV treatment. Factors associated with treatment willingness included not being infected with HIV, having not recently used drugs by injection and having reported physical health problems. Among those not having sought HCV treatment (n=107), the major reasons for not doing so were: lack of information about HCV or knowledge that treatment was available (23%), the absence of symptoms (20%) and the perceived side effects of treatment (14%). Among illicit drug users attending inner city clinics, we have observed a low uptake of HCV treatment, but a high willingness to receive therapy. An increased focus on improving education about the long-term consequences of HCV and the availability of effective treatment are important components for expanding HCV treatment among illicit drug users.

A new website with real-time dissemination of information on fire activity and meteorological fire danger in Portugal

2017-04-01

In Portugal, like in Mediterranean Europe, fire activity is a natural phenomenon linking climate, humans and vegetation and is therefore conditioned by natural and anthropogenic factors. Natural factors include topography, vegetation cover and prevailing weather conditions whereas anthropogenic factors encompass land management practices and fire prevention policies. Land management practices, in particular the inadequate use of fire, is a crucial anthropogenic factor that accounts for about 90% of fire ignitions. Fire prevention policies require adequate and timely information about wildfire potential assessment, which is usually based on fire danger rating systems that provide indices to be used on an operational and tactical basis in decision support systems. We present a new website designed to provide the user community with relevant real-time information on fire activity and meteorological fire danger that will allow adopting the adequate measures to mitigate fire damage. The fire danger product consists of forecasts of fire danger over Portugal based on a statistical procedure that combines information about fire history derived from the Fire Radiative Power product disseminated by the Land Surface Analysis Satellite Application Facility (LSA SAF) with daily meteorological forecasts provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). The aim of the website is fourfold; 1) to concentrate all information available (databases and maps) relevant to fire management in a unique platform so that access by end users becomes easier, faster and friendlier; 2) to supervise the access of users to the different products available; 3) to control and assist the access to the platform and obtain feedbacks from users for further improvements; 4) to outreach the operational community and foster the use of better information that increase efficiency in risk management. The website is sponsored by The Navigator Company, a leading force in the global pulp and paper market. Since the operational start of the website, the number of registered users has been steadily increasing up to a total of 300 users from a wide community that encompasses forest managers, firemen and civil protection officers, personnel from municipalities, academic researchers and private owners.

The community resource management area mechanism: a strategy to manage African forest resources for REDD+.

PubMed

Asare, Rebecca A; Kyei, Andrew; Mason, John J

2013-01-01

Climate change poses a significant threat to Africa, and deforestation rates have increased in recent years. Mitigation initiatives such as REDD+ are widely considered as potentially efficient ways to generate emission reductions (or removals), conserve or sustainably manage forests, and bring benefits to communities, but effective implementation models are lacking. This paper presents the case of Ghana's Community Resource Management Area (CREMA) mechanism, an innovative natural resource governance and landscape-level planning tool that authorizes communities to manage their natural resources for economic and livelihood benefits. This paper argues that while the CREMA was originally developed to facilitate community-based wildlife management and habitat protection, it offers a promising community-based structure and process for managing African forest resources for REDD+. At a theoretical level, it conforms to the ecological, socio-cultural and economic factors that drive resource-users' decision process and practices. And from a practical mitigation standpoint, the CREMA has the potential to help solve many of the key challenges for REDD+ in Africa, including definition of boundaries, smallholder aggregation, free prior and informed consent, ensuring permanence, preventing leakage, clarifying land tenure and carbon rights, as well as enabling equitable benefit-sharing arrangements. Ultimately, CREMA's potential as a forest management and climate change mitigation strategy that generates livelihood benefits for smallholder farmers and forest users will depend upon the willingness of African governments to support the mechanism and give it full legislative backing, and the motivation of communities to adopt the CREMA and integrate democratic decision-making and planning with their traditional values and natural resource management systems.

Recent advances have made these techniques practical and affordable for essentially any laboratory with experience in molecular biology. A variety of computational methods have been developed to decrease the amount of bioinformatics expertise necessary to analyze these data. Nevertheless, many barriers persist which discourage new labs from using functional genomics approaches. Since high-quality gene expression studies have enduring value as resources to the entire research community, it is of particular importance that small labs have the capacity to share their analyzed datasets with the research community. Here we introduce ExpressionDB, an open source platform for visualizing RNA-seq and microarray data accommodating virtually any number of different samples. ExpressionDB is based on Shiny, a customizable web application which allows data sharing locally and online with customizable code written in R. ExpressionDB allows intuitive searches based on gene symbols, descriptions, or gene ontology terms, and it includes tools for dynamically filtering results based on expression level, fold change, and false-discovery rates. Built-in visualization tools include heatmaps, volcano plots, and principal component analysis, ensuring streamlined and consistent visualization to all users. All of the scripts for building an ExpressionDB with user-supplied data are freely available on GitHub, and the Creative Commons license allows fully open customization by end-users. We estimate that a demo database can be created in under one hour with minimal programming experience, and that a new database with user-supplied expression data can be completed and online in less than one day.

Today's communications landscape is rich with new technologies. Cell phones and laptops are the constant companions of content consumers, and as we plan tomorrow's Education and Public Outreach programs, we need to consider how to most effectively utilize these technologies with their new, dynamic content possibilities - We need to use New Media. The field of New Media includes dynamic content sites such as: blogs, pod/vodcasts, Flickr, Facebook, Ustream, Twitter, and Second Life. The first part of this talk will summarize what New Media is available in the field of astronomy. All new media technologies have one thing in common: Users can easily create and input their own content and/or comments. These new media users and content contributors can just as easily be professional researchers, E/PO professionals, amateur astronomers, stay-at-home parents, and school kids. All are welcome in the online community, and today, all voices are digitally joined in the cacophony of astronomy new media content. This rich diversity supports many opportunities for learning, mentoring, content distribution, and discussion of ideas (including the debunking of bad ideas). In the second half of this talk, ways to use new media to build a community that shares, promotes, and comments on content is discussed, and techniques for dealing with the high flux of content are outlined. Also covered are the considerations that need to be made to make content as broadly accessible as possible.

A virtual professional community of practice (VCoP), HOBE+, has been set up to foster and facilitate innovation in primary care. It is aimed at all primary care professionals of the Basque Public Health Service (Osakidetza) in the provinces of Biscay and Araba. HOBE + is a VCoP that incorporates innovation management from the generation of ideas to their implementation in primary care practice. We used a case study method, based on the data provided by the technology platform that supports the VCoP, and from a survey completed by HOBE + users. The target population was all primary care staff (including all professional categories) from Araba and Biscay provinces of the Basque Country (Spain), who represent the target users of the VCoP. From a total of 5190 professionals across all the professional categories invited to join, 1627 (31.3%) actually registered in the VCoP and, during the study period, 90 (5.5% of the registered users) participated actively in some way. The total number of ideas proposed by the registered users was 133. Of these, 23 ideas (17.2%) are being implemented. Finally, 80% of the users who answered the satisfaction survey about their experience with HOBE + considered the initiative useful in order to achieve continuous improvement and real innovation in clinical and managerial processes. The experience shows that it is possible to create a virtual CoP for innovation in primary care where professionals from different professional categories propose ideas for innovation that are ultimately implemented.This manuscript objectives are to assess the process of developing and implementing a VCoP open to all primary care professionals in Osakidetza, including the take-up, participation and use of this VCoP in the first 15 months after its launch in October 2011. In addition, the usefulness of the VCoP was assessed through a survey gathering the opinions of the professionals involved.

Wild and Scenic Rivers provide a host of psychological, social, ecological, and economic benefits to local communities. In this study, we use data collected from recreational users of two Wild and Scenic Rivers to examine perceptions of the benefits provided by the rivers to local communities. Our purposes are (1) to determine if similar perceptions of community benefits exist across the two rivers, (2) to determine if individuals' proximity to the rivers are related to the benefits they perceive, (3) to determine if individuals' prior recreation experience on the river is related to variations in perceived benefits, (4) to determine if users' sociodemographic characteristics are related to perceived community benefits, and (5) to determine if the influence of these characteristics on perceived community benefits is similar across the two resource areas. Perceived benefits were found to be analogous across both rivers as individuals consistently ranked ecological/affective benefits as well as tangible benefits similarly. Recreationists living further from the river ranked ecological and affective benefits as significantly less important than those individuals living closer to the river. Women perceived the community benefits produced by the resource areas to be significantly more important when compared to men. Significant relationships were also found between perceived benefits and recreationists' previous use of the river, their age, and their level of education. With the exception of resource proximity and prior use history, the effects of user characteristics on perceived community benefits were not statistically different across the two rivers. These findings imply similar patterns of perceived community benefits exist across distinct resource areas and that the relationships between user characteristics and perceived benefits are also similar across the study rivers.

Tackling community integration in mental health home visit integration in Finland.

Integration - and its synonym inclusion - is emphasised in the western welfare states and in the European Union in particular. Integration is also a central topic in the social sciences and in current mental health and homelessness research and practice. As mental healthcare has shifted from psychiatric hospitals to the community, it has inevitably become involved with housing and integration issues. This article explores how community integration is understood and tackled in mental health floating support services (FSSs) and, more precisely, in service user-practitioner home visit interaction. The aim, through shedding light on how the idea of integration is present and discussed in front-line mental health practices, is to offer a 'template' on how we might, in a systematic and reflective way, develop community integration research and practice. The analysis is based on ethnomethodological and micro-sociological interaction research. The research settings are two FSSs located in a large Finnish city. The data contain 24 audio-recorded and transcribed home visits conducted in 2011 and 2012 with 16 different service users. The study shows how the participants in service user-practitioner interaction give meaning to community integration and make decisions about how it should (or should not) be enhanced in each individual case. This activity is called community integration work in action. Community integration work in action is based on various dimensions of integration: getting out of the house, participating in group activities and getting along with those involved in one's life and working life. Additionally, the analysis demonstrates how community integration work is accomplished by discursive devices (resistance, positioning, excuses and justifications, delicacy and advice-giving). The article concludes that community integration is about interaction: it is not only service users' individual challenge but also a social challenge, our challenge. © 2015 John Wiley & Sons Ltd.

The impact of realignment on utilization and cost of community-based mental health services in California.

Decentralization of California's public mental health system under program realignment has changed the utilization and cost of community-based mental health services. This study examined a sample of 75,951 users, representing 1.5 million adults who visited California's public mental health services during a 6-year period (FY 1988-1990 and FY 1992-1994). Regression analysis was performed to examine cost and utilization reduction over time, across regions, and across psychiatric diagnoses. Overall utilization and cost of community-based mental health services dropped significantly after the implementation of realignment. They were significantly lower for (a) 24-hour services in the urban industrialized Southern Region and (b) outpatient services in the agricultural Central Region of the state. Users diagnosed with mood disorders took a greater portion, but were associated with significantly less treatment and cost than other users in the post-realignment period. When local communities bear the financial risks and rewards, they find more efficient methods of delivering community-based mental health services.

An approach to and web-based tool for infectious disease outbreak intervention analysis

Infectious diseases are a leading cause of death globally. Decisions surrounding how to control an infectious disease outbreak currently rely on a subjective process involving surveillance and expert opinion. However, there are many situations where neither may be available. Modeling can fill gaps in the decision making process by using available data to provide quantitative estimates of outbreak trajectories. Effective reduction of the spread of infectious diseases can be achieved through collaboration between the modeling community and public health policy community. However, such collaboration is rare, resulting in a lack of models that meet the needs of the public health community. Here we show a Susceptible-Infectious-Recovered (SIR) model modified to include control measures that allows parameter ranges, rather than parameter point estimates, and includes a web user interface for broad adoption. We apply the model to three diseases, measles, norovirus and influenza, to show the feasibility of its use and describe a research agenda to further promote interactions between decision makers and the modeling community.

The involvement of mental health service users and their caregivers in health system policy and planning, service monitoring and research can contribute to mental health system strengthening, but as yet there have been very few efforts to do so in low- and middle-income countries (LMICs). This systematic review examined the evidence and experience of service user and caregiver involvement in mental health system strengthening, as well as models of best practice for evaluation of capacity-building activities that facilitate their greater participation. Both the peer-reviewed and the grey literature were included in the review, which were identified through database searches (MEDLINE, Embase, PsycINFO, Web of Knowledge, Web of Science, Scopus, CINAHL, LILACS, SciELO, Google Scholar and Cochrane), as well as hand-searching of reference lists and the internet, and a snowballing process of contacting experts active in the area. This review included any kind of study design that described or evaluated service user, family or caregiver (though not community) involvement in LMICs (including service users with intellectual disabilities, dementia, or child and adolescent mental health problems) and that were relevant to mental health system strengthening across five categories. Data were extracted and summarised as a narrative review. Twenty papers matched the inclusion criteria. Overall, the review found that although there were examples of service user and caregiver involvement in mental health system strengthening in numerous countries, there was a lack of high-quality research and a weak evidence base for the work that was being conducted across countries. However, there was some emerging research on the development of policies and strategies, including advocacy work, and to a lesser extent the development of services, service monitoring and evaluation, with most service user involvement having taken place within advocacy and service delivery. Research was scarce within the other health system strengthening areas. Further research on service user and caregiver involvement in mental health system strengthening in LMICs is recommended, in particular research that includes more rigorous evaluation. A series of specific recommendations are provided based on the review.

There is widespread use of the Internet to promote anorexia as a lifestyle choice. Pro-anorexia content can be harmful for people affected or at risk of having anorexia. That movement is actively engaged in sharing photos on social networks such as Flickr. To study the characteristics of the online communities engaged in disseminating content that encourages eating disorders (known as "pro-anorexia") and to investigate if the posting of such content is discouraged by the posting of recovery-oriented content. The extraction of pro-anorexia and pro-recovery photographs from the photo sharing site Flickr pertaining to 242,710 photos from 491 users and analyzing four separate social networks therein. Pro-anorexia and pro-recovery communities interact to a much higher degree among themselves than what is expected from the distribution of contacts (only 59-72% of contacts but 74-83% of comments are made to members inside the community). Pro-recovery users employ similar words to those used by pro-anorexia users to describe their photographs, possibly in order to ensure that their content appears when pro-anorexia users search for images. Pro-anorexia users who are exposed to comments from the opposite camp are less likely to cease posting pro-anorexia photographs than those who do not receive such comments (46% versus 61%), and if they cease, they do so approximately three months later. Our observations show two highly active communities, where most interaction is within each community. However, the pro-recovery community takes steps to ensure that their content is visible to the pro-anorexia community, both by using textual descriptions of their photographs that are similar to those used by the pro-anorexia group and by commenting to pro-anorexia content. The latter activity is, however, counterproductive, as it entrenches pro-anorexia users in their stance. Our results highlight the nature of pro-anorexia and pro-recovery photo sharing and accentuate the need for clinicians to be aware of such content and its effect on their patients. Our findings suggest that some currently used interventions are not useful in helping pro-anorexia users recover. Thus, future work should focus on new intervention methods, possibly tailored to individual characteristics.

There is a paucity of available strategies to increase visibility and engagement in social media (SM) within the neurosurgical community. The objective of this study was to investigate the possible factors for engagement and reach among SM users in neurosurgery. Data from Facebook and Twitter accounts of our institution were collected. We extracted data on demographics and attributes of our current users, including sex, country, age group, device used, and language. Attributes of SM posts were also collected, including time of post, type and content of post, impressions, and engagements. Nonparametric analyses were conducted to evaluate differences in metrics. Metrics were obtained on 192 Facebook and Twitter posts, published online between October 1, 2013, and March 13, 2016. On both platforms, there was a greater representation of male users relative to female users. Facebook users were predominantly in the 18-34 years age range (83%), with most users being from outside of North America. Conversely, users from Canada and the United States comprised the highest proportion of Twitter users. On both platforms, posts containing photos or videos scored significantly higher in engagements and impressions (P < 0.05). Posts on weekdays and during work hours achieved higher visibility and engagements. Moreover, Facebook posts demonstrated higher SM metrics if they mentioned faculty with more than 16 years' experience (P < 0.05). The current study demonstrates that our SM users predominantly comprise a younger demographic and that content optimization with media materials may lead to higher visibility and engagement. The impact of high SM reach on academic neurosurgical programs remains to be determined. Copyright © 2016 Elsevier Inc. All rights reserved.

The NCAR Research Data Archive's Hybrid Approach for Data Discovery and Access

NASA Astrophysics Data System (ADS)

Schuster, D.; Worley, S. J.

2013-12-01

The NCAR Research Data Archive (RDA http://rda.ucar.edu) maintains a variety of data discovery and access capabilities for it's 600+ dataset collections to support the varying needs of a diverse user community. In-house developed and standards-based community tools offer services to more than 10,000 users annually. By number of users the largest group is external and access the RDA through web based protocols; the internal NCAR HPC users are fewer in number, but typically access more data volume. This paper will detail the data discovery and access services maintained by the RDA to support both user groups, and show metrics that illustrate how the community is using the services. The distributed search capability enabled by standards-based community tools, such as Geoportal and an OAI-PMH access point that serves multiple metadata standards, provide pathways for external users to initially discover RDA holdings. From here, in-house developed web interfaces leverage primary discovery level metadata databases that support keyword and faceted searches. Internal NCAR HPC users, or those familiar with the RDA, may go directly to the dataset collection of interest and refine their search based on rich file collection metadata. Multiple levels of metadata have proven to be invaluable for discovery within terabyte-sized archives composed of many atmospheric or oceanic levels, hundreds of parameters, and often numerous grid and time resolutions. Once users find the data they want, their access needs may vary as well. A THREDDS data server running on targeted dataset collections enables remote file access through OPENDAP and other web based protocols primarily for external users. In-house developed tools give all users the capability to submit data subset extraction and format conversion requests through scalable, HPC based delayed mode batch processing. Users can monitor their RDA-based data processing progress and receive instructions on how to access the data when it is ready. External users are provided with RDA server generated scripts to download the resulting request output. Similarly they can download native dataset collection files or partial files using Wget or cURL based scripts supplied by the RDA server. Internal users can access the resulting request output or native dataset collection files directly from centralized file systems.

Dynamic robustness of knowledge collaboration network of open source product development community

2018-01-01

As an emergent innovative design style, open source product development communities are characterized by a self-organizing, mass collaborative, networked structure. The robustness of the community is critical to its performance. Using the complex network modeling method, the knowledge collaboration network of the community is formulated, and the robustness of the network is systematically and dynamically studied. The characteristics of the network along the development period determine that its robustness should be studied from three time stages: the start-up, development and mature stages of the network. Five kinds of user-loss pattern are designed, to assess the network's robustness under different situations in each of these three time stages. Two indexes - the largest connected component and the network efficiency - are used to evaluate the robustness of the community. The proposed approach is applied in an existing open source car design community. The results indicate that the knowledge collaboration networks show different levels of robustness in different stages and different user loss patterns. Such analysis can be applied to provide protection strategies for the key users involved in knowledge dissemination and knowledge contribution at different stages of the network, thereby promoting the sustainable and stable development of the open source community.

Quantarctica: A Unique, Open, Standalone GIS Package for Antarctic Research and Education

The Norwegian Polar Institute has developed Quantarctica, an open GIS package for use by the international Antarctic community. Quantarctica includes a wide range of cartographic basemap layers, geophysical and glaciological datasets, and satellite imagery in standardized file formats with a consistent Antarctic map projection and customized layer and labeling styles for quick, effective cartography. Quantarctica's strengths as an open science platform lie in 1) The complete, ready-to-use data package which includes full-resolution, original-quality vector and raster data, 2) A policy for freely-redistributable and modifiable data including all metadata and citations, and 3) QGIS, a free, full-featured, modular, offline-capable open-source GIS suite with a rapid and active development and support community. The Quantarctica team is actively seeking new contributions of peer-reviewed, freely distributable pan-Antarctic geospatial datasets for the next version release in 2017. As part of this ongoing development, we are investigating the best approaches for quickly and seamlessly distributing new and updated data to users, storing datasets in efficient file formats while maintaining full quality, and coexisting with numerous online data portals in a way that most actively benefits the Antarctic community. A recent survey of Quantarctica users showed broad geographical adoption among Antarctic Treaty countries, including those outside the large US and UK Antarctic programs. Maps and figures produced by Quantarctica have also appeared in open-access journals and outside of the formal scientific community on popular science and GIS blogs. Our experience with the Quantarctica project has shown the tremendous value of education and outreach, not only in promoting open software, data formats, and practices, but in empowering Antarctic science groups to more effectively use GIS and geospatial data. Open practices are making a huge impact in Antarctic GIS, where individual countries have historically maintained their own restricted Antarctic geodatabases and where a majority of the next generation of scientists are entering the field with experience in using geospatial thinking for planning, visualization, and problem solving.

Community-Supported Data Repositories in Paleobiology: A 'Middle Tail' Between the Geoscientific and Informatics Communities

Community-supported data repositories (CSDRs) in paleoecology and paleoclimatology have a decades-long tradition and serve multiple critical scientific needs. CSDRs facilitate synthetic large-scale scientific research by providing open-access and curated data that employ community-supported metadata and data standards. CSDRs serve as a 'middle tail' or boundary organization between information scientists and the long-tail community of individual geoscientists collecting and analyzing paleoecological data. Over the past decades, a distributed network of CSDRs has emerged, each serving a particular suite of data and research communities, e.g. Neotoma Paleoecology Database, Paleobiology Database, International Tree Ring Database, NOAA NCEI for Paleoclimatology, Morphobank, iDigPaleo, and Integrated Earth Data Alliance. Recently, these groups have organized into a common Paleobiology Data Consortium dedicated to improving interoperability and sharing best practices and protocols. The Neotoma Paleoecology Database offers one example of an active and growing CSDR, designed to facilitate research into ecological and evolutionary dynamics during recent past global change. Neotoma combines a centralized database structure with distributed scientific governance via multiple virtual constituent data working groups. The Neotoma data model is flexible and can accommodate a variety of paleoecological proxies from many depositional contests. Data input into Neotoma is done by trained Data Stewards, drawn from their communities. Neotoma data can be searched, viewed, and returned to users through multiple interfaces, including the interactive Neotoma Explorer map interface, REST-ful Application Programming Interfaces (APIs), the neotoma R package, and the Tilia stratigraphic software. Neotoma is governed by geoscientists and provides community engagement through training workshops for data contributors, stewards, and users. Neotoma is engaged in the Paleobiological Data Consortium and other efforts to improve interoperability among cyberinfrastructure in the paleogeosciences.

This paper describes a proposed best-practices system that will present expert knowledge in the use of CFD. The best-practices system will include specific guidelines to assist the user in problem definition, input preparation, grid generation, code selection, parameter specification, and results interpretation. The goal of the system is to assist all CFD users in obtaining high quality CFD solutions with reduced uncertainty and at lower cost for a wide range of flow problems. The best-practices system will be implemented as a software product which includes an expert system made up of knowledge databases of expert information with specific guidelines for individual codes and algorithms. The process of acquiring expert knowledge is discussed, and help from the CFD community is solicited. Benefits and challenges associated with this project are examined.

Recent findings showed that users on Facebook tend to select information that adhere to their system of beliefs and to form polarized groups - i.e., echo chambers. Such a tendency dominates information cascades and might affect public debates on social relevant issues. In this work we explore the structural evolution of communities of interest by accounting for users emotions and engagement. Focusing on the Facebook pages reporting on scientific and conspiracy content, we characterize the evolution of the size of the two communities by fitting daily resolution data with three growth models - i.e. the Gompertz model, the Logistic model, and the Log-logistic model. Although all the models appropriately describe the data structure, the Logistic one shows the best fit. Then, we explore the interplay between emotional state and engagement of users in the group dynamics. Our findings show that communities' emotional behavior is affected by the users' involvement inside the echo chamber. Indeed, to an higher involvement corresponds a more negative approach. Moreover, we observe that, on average, more active users show a faster shift towards the negativity than less active ones.

Kameleon Live: An Interactive Cloud Based Analysis and Visualization Platform for Space Weather Researchers

2015-12-01

The Community Coordinated Modeling Center (CCMC) provides hosting for many of the simulations used by the space weather community of scientists, educators, and forecasters. CCMC users may submit model runs through the Runs on Request system, which produces static visualizations of model output in the browser, while further analysis may be performed off-line via Kameleon, CCMC's cross-language access and interpolation library. Off-line analysis may be suitable for power-users, but storage and coding requirements present a barrier to entry for non-experts. Moreover, a lack of a consistent framework for analysis hinders reproducibility of scientific findings. To that end, we have developed Kameleon Live, a cloud based interactive analysis and visualization platform. Kameleon Live allows users to create scientific studies built around selected runs from the Runs on Request database, perform analysis on those runs, collaborate with other users, and disseminate their findings among the space weather community. In addition to showcasing these novel collaborative analysis features, we invite feedback from CCMC users as we seek to advance and improve on the new platform.

In their 2005 study, Adamic and Glance coined the memorable phrase 'divided they blog', referring to a trend of cyberbalkanization in the political blogosphere, with liberal and conservative blogs tending to link to other blogs with a similar political slant, and not to one another. As political discussion and activity increasingly moves online, the power of framing political discourses is shifting from mass media to social media. Continued examination of political interactions online is critical, and we extend this line of research by examining the activities of political users within the Wikipedia community. First, we examined how users in Wikipedia choose to display their political affiliation. Next, we analyzed the patterns of cross-party interaction and community participation among those users proclaiming a political affiliation. In contrast to previous analyses of other social media, we did not find strong trends indicating a preference to interact with members of the same political party within the Wikipedia community. Our results indicate that users who proclaim their political affiliation within the community tend to proclaim their identity as a 'Wikipedian' even more loudly. It seems that the shared identity of 'being Wikipedian' may be strong enough to triumph over other potentially divisive facets of personal identity, such as political affiliation.

India has 275 million adult tobacco users and tobacco use is estimated to contribute to more than a million deaths in the country each year. There is an urgent need to develop and evaluate affordable, practicable and scalable interventions to promote cessation of tobacco use. Because tobacco use is so harmful, an increase of as little as 1 percentage point in long-term quit success rates can have an important public health impact. This protocol paper describes the rationale and methods of a large randomized controlled trial which aims to evaluate the effectiveness of a brief scalable smoking cessation intervention delivered by trained health professionals as an outreach programme in poor urban communities in India. This is a pragmatic, two-arm, community-based cluster randomized controlled trial focused on tobacco users in low-income communities. The treatment arm is a brief intervention comprising brief advice including training in craving control using simple yogic breathing exercises (BA-YBA) and the control arm is very brief advice (VBA). Of a total of 32 clusters, 16 will be allocated to the intervention arm and 16 to the control arm. Each cluster will have 31 participants, making a total of 992 participants. The primary outcome measure will follow the Russell Standard: self-report of sustained abstinence for at least 6 months following the intervention confirmed at the final follow-up by salivary cotinine. This trial will inform national and international policy on delivery of scalable and affordable brief outreach interventions to promote tobacco use cessation in low resource settings where tobacco users have limited access to physicians and medications. © 2014 Society for the Study of Addiction.

People with disabilities are more likely to be obese, in poor health, and get less physical activity than the general population. However, research on community factors for physical activity has generally either excluded most people with disabilities, or overlooked relevant factors of community accessibility. This exploratory study investigated environmental factors affecting people with motor impairments and people with visual impairments in urban neighborhoods. Quantitative and qualitative methods were used with a nonrandom sample (n=134) of users of four types of assistive mobility technologies: guide dogs, long canes, and motorized and manual wheelchairs. From July 2005 to August 2006, the sample participated in two telephone surveys. Between the surveys, a stratified random subsample (n =32) engaged in an ethnographic phase of observation and interviews. Most participants in all groups using assistive mobility technologies rated their neighborhoods as accessible, although they also reported many specific barriers. Users of assistive mobility technologies differed in the amount of reported physical activity and on specific barriers. Problems with sidewalk pavement and puddles/poor drainage were the most frequently mentioned environmental barriers, by 90% and 80%, respectively. Users of assistive mobility technologies were more similar on main strategies for dealing with barriers. All groups reported having to plan routes for outings, to alter planned routes, to go more slowly than planned, or to wait for a different time. Despite legislative requirements for accommodation, people with disabilities face barriers to physical activity, both in the built and social environments. Determined people with disabilities were able to overcome barriers, but required additional expenditure of resources to do so. Community design that can include people with disabilities requires detailed understanding of barriers specific both to types of impairments and to different types of assistive mobility technologies.

Introduction While relatively rare events, abrupt disruptions in heroin availability have a significant impact on morbidity and mortality risk among those who are heroin dependent. A heroin shortage occurred in Coast Province, Kenya from December 2010 to March 2011. This qualitative analysis describes the shortage events and consequences from the perspective of heroin users, along with implications for health and other public sectors. Methods As part of a rapid assessment, 66 key informant interviews and 15 focus groups among heroin users in Coast Province, Kenya were conducted. A qualitative thematic analysis was undertaken in Atlas.ti. to identify salient themes related to the shortage. Results Overall, participant accounts were rooted in a theme of desperation and uncertainty, with emphasis on six sub-themes: (1) withdrawal and strategies for alleviating withdrawal, including use of medical intervention and other detoxification attempts; (2) challenges of dealing with unpredictable drug availability, cost, and purity; (3) changes in drug use patterns, and actions taken to procure heroin and other drugs; (4) modifications in drug user relationship dynamics and networks, including introduction of risky group-level injection practices; (5) family and community response; and (6) new challenges with the heroin market resurgence. Conclusions The heroin shortage led to a series of consequences for drug users, including increased risk of morbidity, mortality and disenfranchisement at social and structural levels. Availability of evidence-based services for drug users and emergency preparedness plans could have mitigated this impact. PMID:26470646

Background RNA sequencing (RNA-seq) is emerging as a critical approach in biological research. However, its high-throughput advantage is significantly limited by the capacity of bioinformatics tools. The research community urgently needs user-friendly tools to efficiently analyze the complicated data generated by high throughput sequencers. Results We developed a standalone tool with graphic user interface (GUI)-based analytic modules, known as eRNA. The capacity of performing parallel processing and sample management facilitates large data analyses by maximizing hardware usage and freeing users from tediously handling sequencing data. The module miRNA identification” includes GUIs for raw data reading, adapter removal, sequence alignment, and read counting. The module “mRNA identification” includes GUIs for reference sequences, genome mapping, transcript assembling, and differential expression. The module “Target screening” provides expression profiling analyses and graphic visualization. The module “Self-testing” offers the directory setups, sample management, and a check for third-party package dependency. Integration of other GUIs including Bowtie, miRDeep2, and miRspring extend the program’s functionality. Conclusions eRNA focuses on the common tools required for the mapping and quantification analysis of miRNA-seq and mRNA-seq data. The software package provides an additional choice for scientists who require a user-friendly computing environment and high-throughput capacity for large data analysis. eRNA is available for free download at https://sourceforge.net/projects/erna/?source=directory.

SESAR, the System for Earth Sample Registration, is an online registry for physical samples collected for Earth and environmental studies. SESAR generates and administers the International Geo Sample Number IGSN, a unique identifier for samples that is dramatically advancing interoperability amongst information systems for sample-based data. SESAR was developed to provide the complete range of registry services, including definition of IGSN syntax and metadata profiles, registration and validation of name spaces requested by users, tools for users to submit and manage sample metadata, validation of submitted metadata, generation and validation of the unique identifiers, archiving of sample metadata, and public or private access to the sample metadata catalog. With the development of SESAR v3, we placed particular emphasis on creating enhanced tools that make metadata submission easier and more efficient for users, and that provide superior functionality for users to manage metadata of their samples in their private workspace MySESAR. For example, SESAR v3 includes a module where users can generate custom spreadsheet templates to enter metadata for their samples, then upload these templates online for sample registration. Once the content of the template is uploaded, it is displayed online in an editable grid format. Validation rules are executed in real-time on the grid data to ensure data integrity. Other new features of SESAR v3 include the capability to transfer ownership of samples to other SESAR users, the ability to upload and store images and other files in a sample metadata profile, and the tracking of changes to sample metadata profiles. In the next version of SESAR (v3.5), we will further improve the discovery, sharing, registration of samples. For example, we are developing a more comprehensive suite of web services that will allow discovery and registration access to SESAR from external systems. Both batch and individual registrations will be possible through web services. Based on valuable feedback from the user community, we will introduce enhancements that add greater flexibility to the system to accommodate the vast diversity of metadata that users want to store. Users will be able to create custom metadata fields and use these for the samples they register. Users will also be able to group samples into 'collections' to make retrieval for research projects or publications easier. An improved interface design will allow for better workflow transition and navigation throughout the application. In keeping up with the demands of a growing community, SESAR has also made process changes to ensure efficiency in system development. For example, we have implemented a release cycle to better track enhancements and fixes to the system, and an API library that facilitates reusability of code. Usage tracking, metrics and surveys capture information to guide the direction of future developments. A new set of administrative tools allows greater control of system management.

Skilled website developers value usability testing to assure user needs are met. When the target audience differs substantially from the developers, it becomes essential to tailor both design and evaluation methods. In this study, researchers carried out a multifaceted usability evaluation of a website (Healthy Texas) designed for Hispanic audiences with lower computer literacy and lower health literacy. METHODS INCLUDED: (1) heuristic evaluation by a usability engineer, (2) remote end-user testing using WebEx software; and (3) face-to-face testing in a community center where use of the website was likely. Researchers found standard usability testing methods needed to be modified to provide interpreters, increased flexibility for time on task, presence of a trusted intermediary such as a librarian, and accommodation for family members who accompanied participants. Participants offered recommendations for website redesign, including simplified language, engaging and relevant graphics, culturally relevant examples, and clear navigation. User-centered design is especially important when website developers are not representative of the target audience. Failure to conduct appropriate usability testing with a representative audience can substantially reduce use and value of the website. This thorough course of usability testing identified improvements that benefit all users but become crucial when trying to reach an underserved audience.

Background African Americans are incarcerated at rates much higher than other racial and ethnic groups in the United States. Objectives We sought to qualitatively explore the relationships between ongoing involvement in the criminal justice system and continued drug use in a population of urban and rural African American cocaine users in a southern state. Methods Semi-structured qualitative interviews were conducted among African American cocaine users in Arkansas between 2010 and 2012. Participants resided in both rural (two counties located in the eastern Arkansas Mississippi delta region) and urban (the county including the capital city of Little Rock) areas. Results Numerous important themes emerged from participants’ narratives, including chronic involvement with the criminal justice system (being a “career criminal”), continued access to drugs while incarcerated, relapse, and reincarceration and lack of access to effective drug treatment. Conclusion/Importance The themes which emerged from our data speak to the collective experience that many substance using populations in the United States face in dealing with the criminal justice system. Our findings highlight the need to better, more holistic ways of engaging African American substance users in community based substance use treatment and supportive services. PMID:27486889
