The U.S. Global Change Research Program Sustained Assessment process benefits from long-term investments in Earth science research that enable the scientific community to conduct assessment-relevant science. To this end, NASA initiated several research programs over the past five years to support the Earth observation community in developing indicators, datasets, research products, and tools to support ongoing and future National Climate Assessments. These activities complement NASA's ongoing Earth science research programs. One aspect of the assessment portfolio funds four "enabling tools" projects at NASA research centers. Each tool leverages existing capacity within the center, but has developed tailored applications and products for National Climate Assessments. The four projects build on the capabilities of a global atmospheric reanalysis (MERRA-2), a continental U.S. land surface reanalysis (NCA-LDAS), the NASA Earth Exchange (NEX), and a Regional Climate Model Evaluation System (RCMES). Here, we provide a brief overview of each enabling tool, highlighting the ways in which it has advanced assessment science to date. We also discuss how the assessment community can access and utilize these tools for National Climate Assessments and other sustained assessment activities.

Xu, Hua; Anderson, Kristin; Grann, Victor R; Friedman, Carol

2004-01-01

Many ongoing clinical research projects, such as projects involving studies associated with cancer, involve manual capture of information in surgical pathology reports so that the information can be used to determine the eligibility of recruited patients for the study and to provide other information, such as cancer prognosis. Natural language processing (NLP) systems offer an alternative to automated coding, but pathology reports have certain features that are difficult for NLP systems. This paper describes how a preprocessor was integrated with an existing NLP system (MedLEE) in order to reduce modification to the NLP system and to improve performance. The work was done in conjunction with an ongoing clinical research project that assesses disparities and risks of developing breast cancer for minority women. An evaluation of the system was performed using manually coded data from the research project's database as a gold standard. The evaluation outcome showed that the extended NLP system had a sensitivity of 90.6% and a precision of 91.6%. Results indicated that this system performed satisfactorily for capturing information for the cancer research project.

Is It Time To Consider Global Sharing of Integral Physics Data?

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

Harold F. McFarlane

The innocent days of the Atoms for Peace program vanished with the suicide attack on the World Trade Center in New York City that occurred while the GLOBAL 2001 international nuclear fuel cycle conference was convened in Paris. Today’s reality is that maintaining an inventory of unirradiated highly enriched uranium or plutonium for critical experiments requires a facility to accept substantial security cost and intrusion. In the context of a large collection of benchmark integral experiments collected over several decades and the ongoing rapid advances in computer modeling and simulation, there seems to be ample incentive to reduce both themore » number of facilities and material inventory quantities worldwide. As a result of ongoing nonproliferation initiatives, there are viable programs that will accept highly enriched uranium for down blending into commercial fuel. Nevertheless, there are formidable hurdles to overcome before national institutions will voluntarily give up existing nuclear research capabilities. GLOBAL 2005 was the appropriate forum to begin fostering a new spirit of cooperation that could lead to improved international security and better use of precious research and development resources, while ensuring access to existing and future critical experiment data.« less

Developing a national health research system: participatory approaches to legislative, institutional and networking dimensions in Zambia.

PubMed

Chanda-Kapata, Pascalina; Campbell, Sandy; Zarowsky, Christina

2012-06-06

For many sub-Saharan African countries, a National Health Research System (NHRS) exists more in theory than in reality, with the health system itself receiving the majority of investments. However, this lack of attention to NHRS development can, in fact, frustrate health systems in achieving their desired goals. In this case study, we discuss the ongoing development of Zambia's NHRS. We reflect on our experience in the ongoing consultative development of Zambia's NHRS and offer this reflection and process documentation to those engaged in similar initiatives in other settings. We argue that three streams of concurrent activity are critical in developing an NHRS in a resource-constrained setting: developing a legislative framework to determine and define the system's boundaries and the roles all actors will play within it; creating or strengthening an institution capable of providing coordination, management and guidance to the system; and focusing on networking among institutions and individuals to harmonize, unify and strengthen the overall capacities of the research community.

To guide efficient investment of limited health resources in sub-Saharan Africa, local researchers need to be involved in, and guide, health system and policy research. While extensive survey and census data are available to health researchers and program officers in resource-limited countries, local involvement and leadership in research is limited due to inadequate experience, lack of dedicated research time and weak interagency connections, among other challenges. Many research-strengthening initiatives host prolonged fellowships out-of-country, yet their approaches have not been evaluated for effectiveness in involvement and development of local leadership in research. We developed, implemented and evaluated a multi-month, deliverable-driven, survey analysis training based in Rwanda to strengthen skills of five local research leaders, 15 statisticians, and a PhD candidate. Research leaders applied with a specific research question relevant to country challenges and committed to leading an analysis to publication. Statisticians with prerequisite statistical training and experience with a statistical software applied to participate in class-based trainings and complete an assigned analysis. Both statisticians and research leaders were provided ongoing in-country mentoring for analysis and manuscript writing. Participants reported a high level of skill, knowledge and collaborator development from class-based trainings and out-of-class mentorship that were sustained 1 year later. Five of six manuscripts were authored by multi-institution teams and submitted to international peer-reviewed scientific journals, and three-quarters of the participants mentored others in survey data analysis or conducted an additional survey analysis in the year following the training. Our model was effective in utilizing existing survey data and strengthening skills among full-time working professionals without disrupting ongoing work commitments and using few resources. Critical to our success were a transparent, robust application process and time limited training supplemented by ongoing, in-country mentoring toward manuscript deliverables that were led by Rwanda's health research leaders.

Collaborative Data Publication Utilizing the Open Data Repository's (ODR) Data Publisher

NASA Technical Reports Server (NTRS)

Stone, N.; Lafuente, B.; Bristow, T.; Keller, R. M.; Downs, R. T.; Blake, D.; Fonda, M.; Dateo, C.; Pires, A.

Introduction: For small communities in diverse fields such as astrobiology, publishing and sharing data can be a difficult challenge. While large, homogenous fields often have repositories and existing data standards, small groups of independent researchers have few options for publishing standards and data that can be utilized within their community. In conjunction with teams at NASA Ames and the University of Arizona, the Open Data Repository's (ODR) Data Publisher has been conducting ongoing pilots to assess the needs of diverse research groups and to develop software to allow them to publish and share their data collaboratively. Objectives: The ODR's Data Publisher aims to provide an easy-to-use and implement software tool that will allow researchers to create and publish database templates and related data. The end product will facilitate both human-readable interfaces (web-based with embedded images, files, and charts) and machine-readable interfaces utilizing semantic standards. Characteristics: The Data Publisher software runs on the standard LAMP (Linux, Apache, MySQL, PHP) stack to provide the widest server base available. The software is based on Symfony (www.symfony.com) which provides a robust framework for creating extensible, object-oriented software in PHP. The software interface consists of a template designer where individual or master database templates can be created. A master database template can be shared by many researchers to provide a common metadata standard that will set a compatibility standard for all derivative databases. Individual researchers can then extend their instance of the template with custom fields, file storage, or visualizations that may be unique to their studies. This allows groups to create compatible databases for data discovery and sharing purposes while still providing the flexibility needed to meet the needs of scientists in rapidly evolving areas of research. Research: As part of this effort, a number of ongoing pilot and test projects are currently in progress. The Astrobiology Habitable Environments Database Working Group is developing a shared database standard using the ODR's Data Publisher and has a number of example databases where astrobiology data are shared. Soon these databases will be integrated via the template-based standard. Work with this group helps determine what data researchers in these diverse fields need to share and archive. Additionally, this pilot helps determine what standards are viable for sharing these types of data from internally developed standards to existing open standards such as the Dublin Core (http://dublincore.org) and Darwin Core (http://rs.twdg.org) metadata standards. Further studies are ongoing with the University of Arizona Department of Geosciences where a number of mineralogy databases are being constructed within the ODR Data Publisher system. Conclusions: Through the ongoing pilots and discussions with individual researchers and small research teams, a definition of the tools desired by these groups is coming into focus. As the software development moves forward, the goal is to meet the publication and collaboration needs of these scientists in an unobtrusive and functional way.

Interactions between patients and dental care providers: does gender matter?

PubMed

Inglehart, Marita R

2013-04-01

Research findings concerning the role of gender in patient-physician interactions can inform considerations about the role of gender in patient-dental care provider interactions. Medical research showed that gender differences in verbal and nonverbal communication in medical settings exist and that they affect the outcomes of these interactions. The process of communication is shaped by gender identities, gender stereotypes, and attitudes. Future research needs to consider the cultural complexity and diversity in which gender issues are embedded and the degree to which ongoing value change will shape gender roles and in turn interactions between dental patients and their providers.

Implications of prioritizing HIV cure: new momentum to overcome old challenges in HIV.

PubMed

Tucker, Joseph D; Gilbertson, Adam; Lo, Ying-Ru; Vitória, Marco

2016-03-03

Curing HIV is a new strategic priority for several major AIDS organizations. In step with this new priority, HIV cure research and related programs are advancing in low, middle, and high-income country settings. This HIV cure momentum may influence existing HIV programs and research priorities. Despite the early stage of ongoing HIV cure efforts, these changes have directly influenced HIV research funding priorities, pilot programs, and HIV messaging. The building momentum to cure HIV infection may synergize with strategic priorities to better identify adults and infants with very early HIV infection. Although HIV cure represents a new goal, many existing programs and research techniques can be repurposed towards an HIV cure. HIV messages focused on engaging communities towards an HIV cure need to be careful to promote ARV adherence and retention within the HIV continuum of care. An increased emphasis within the AIDS field on finding an HIV cure has several important implications. Strengthening connections between HIV cure research and other areas of HIV research may help to catalyze research and facilitate implementation in the future.

Public Willingness to Participate in and Public Opinions About Genetic Variation Research: A Review of the Literature

PubMed Central

Sterling, Rene; Henderson, Gail E.; Corbie-Smith, Giselle

2006-01-01

Scientists are turning to genetic variation research in hopes of addressing persistent racial/ethnic disparities in health. Despite ongoing controversy, the advancement of genetic variation research is likely to produce new knowledge and technologies that will substantially change the ways in which we understand and value health. They also may affect the ways in which individuals and groups organize socially, politically, and economically. Addressing concerns that may exist in different communities is vital to the scientific and ethical advancement of genetic variation research. We review empirical studies of public willingness to participate in and opinions about genetic research with particular attention to differences in consent and opinion by racial/ethnic group membership.

Developing a Process for Sustained Climate Assessment in the US Southwest Region

NASA Astrophysics Data System (ADS)

Duncan, B.; Rick, U. K.; McNie, E. C.

2017-12-01

Climate information needs often vary across states, regions, and sectors. While a national assessment provides foundational guidance about the science and impacts of climate change, there is also value in an ongoing climate assessment process with a more targeted regional geographic scale and sectoral focus. Such a process could provide timely and relevant climate information that is sometimes more detailed than what can be included in a national assessment, while also providing a foundation of knowledge and relationships that can be drawn on in larger-scale assessment processes. In the Sustained Climate Assessment in the Southwest project, researchers are investigating opportunities for sustained assessment in the US Southwest National Climate Assessment (NCA) region - an area that consists of Arizona, California, Colorado, Nevada, New Mexico, and Utah. This work is focused on identifying key elements of an ongoing climate assessment process for the region in collaboration with climate service providers and users, with the goal of connecting providers and users to increase access to information and understanding of climate impacts in decision-making contexts. It is focused on four key sectors that represent a range of existing capacity in the region: water, oceans and coasts, agriculture, and transportation. Recommendations for an ongoing assessment process may vary by sector - a reflection of the capacity and opportunity associated with each. In this presentation, we will share case studies of particularly useful or successful existing assessment activities and identify common characteristics across the case studies. We will also share preliminary recommendations for a regional sustained climate assessment process that draws on the broad existing capacity for climate assessment in the region and complements national-scale assessment processes.

Renovating existing space to meet special needs for outpatient paediatric oncology.

PubMed

Rhodes, D A

1999-01-01

Many existing hospital buildings are inadequate to meet needs caused by a tremendous shift from inpatient to outpatient care. Expensive diagnostic and treatment facilities must still be shared by inpatients and outpatients, which in many cases makes renovations to existing facilities on site more appealing than new free-standing facilities; However, care must be taken in the planning and design to make sure that existing hospital operations can be maintained throughout this work. St. Jude Children's Research Hospital in Memphis, an internationally acclaimed institution devoted to the research and treatment of catastrophic illnesses in children has experienced a large growth in its outpatients' care due mainly to changes in treatment modalities and the development of more effective cures. The result has been an extreme overcrowding and unpleasant experiences for patient and family due to awkward patient flow and work processes attempting to respond to the inadequate facility conditions. This paper will not only review the planning issues, but will discuss the renovation which will require several phases in order to minimise disruption to the ongoing activities.

Castro, Felipe González; Kellison, Joshua G.; Boyd, Stephen J.; Kopak, Albert

2011-01-01

Mixed methods research has gained visibility within the last few years, although limitations persist regarding the scientific caliber of certain mixed methods research designs and methods. The need exists for rigorous mixed methods designs that integrate various data analytic procedures for a seamless transfer of evidence across qualitative and quantitative modalities. Such designs can offer the strength of confirmatory results drawn from quantitative multivariate analyses, along with “deep structure” explanatory descriptions as drawn from qualitative analyses. This article presents evidence generated from over a decade of pilot research in developing an integrative mixed methods methodology. It presents a conceptual framework and methodological and data analytic procedures for conducting mixed methods research studies, and it also presents illustrative examples from the authors' ongoing integrative mixed methods research studies.

2010-01-01

Genomics and bioinformatics are dynamic fields well-suited for capturing the imagination of undergraduates in both research laboratories and classrooms. Currently, raw nucleotide sequence is being provided, as part of several genomics research initiatives, for undergraduate research and teaching. These initiatives could be easily extended and much more effective if the source of the sequenced material and the subsequent focus of the data analysis were aligned with the research interests of individual faculty at undergraduate institutions. By judicious use of surplus capacity in existing nucleotide sequencing cores, raw sequence data could be generated to support ongoing research efforts involving undergraduates. This would allow these students to participate actively in discovery research, with a goal of making novel contributions to their field through original research while nurturing the next generation of talented research scientists.

The Patient-Centered Outcomes Research Institute has accelerated conversations about the importance of actively engaging stakeholders in all aspects of comparative effectiveness research (CER). Other scientific disciplines have a history of stakeholder engagement, yet few empirical examples exist of how these stakeholders can inform and enrich CER. Here we present a case study which includes the methods used to engage stakeholders, what we learned from them, and how we incorporated their ideas in a CER project. We selected stakeholders from key groups, built relationships with them and collected their feedback through interviews, observation and ongoing meetings during the four research process phases: proposal development, adapting study methods, understanding the context and information technology tool design and refinement.

The Patient-Centered Outcomes Research Institute has accelerated conversations about the importance of actively engaging stakeholders in all aspects of comparative effectiveness research (CER). Other scientific disciplines have a history of stakeholder engagement, yet few empirical examples exist of how these stakeholders can inform and enrich CER. Here we present a case study which includes the methods used to engage stakeholders, what we learned from them, and how we incorporated their ideas in a CER project. We selected stakeholders from key groups, built relationships with them and collected their feedback through interviews, observation and ongoing meetings during the four research process phases: proposal development, adapting study methods, understanding the context and information technology tool design and refinement.

This paper focuses on whether the on-going dramatic decrease in alcohol consumption in Italy, especially of wine, during 1961-2008, was associated with which parallel sociodemographic and economic changes and with alcohol control policies. The study, using both time series (TS) and artificial neural network (ANN)-based analyses documents that its selected sociodemographic and economic factors, and particularly urbanization, had a definite connection with wine consumption decrease, spirits decrease, and the increase in beer consumption over time. On the other hand, control policies showed no effect on the decline in alcohol consumption, since no alcohol control policy existed in Italy between 1960 and 1987. A few policies introduced since 1988 (BAC and sale restrictions during mass events) may have contributed to reducing or to maintaining the on-going reduction. Study limitations are noted and future needed research is suggested.

HERMIES-I: a mobile robot for navigation and manipulation experiments

The purpose of this paper is to report the current status of investigations ongoing at the Center for Engineering Systems Advanced Research (CESAR) in the areas of navigation and manipulation in unstructured environments. The HERMIES-I mobile robot, a prototype of a series which contains many of the major features needed for remote work in hazardous environments is discussed. Initial experimental work at CESAR has begun in the area of navigation. It briefly reviews some of the ongoing research in autonomous navigation and describes initial research with HERMIES-I and associated graphic simulation. Since the HERMIES robots will generally be composed ofmore » a variety of asynchronously controlled hardware components (such as manipulator arms, digital image sensors, sonars, etc.) it seems appropriate to consider future development of the HERMIES brain as a hypercube ensemble machine with concurrent computation and associated message passing. The basic properties of such a hypercube architecture are presented. Decision-making under uncertainty eventually permeates all of our work. Following a survey of existing analytical approaches, it was decided that a stronger theoretical basis is required. As such, this paper presents the framework for a recently developed hybrid uncertainty theory. 21 refs., 2 figs.« less

To describe the state of research ethics policies and practices in health research institutions in sub-Saharan African countries. A structured questionnaire was used to solicit information on research ethics from health research institutions. Forty-two sub-Saharan African countries. Key informants from the health research institutions. Existence of institutional ethics review policies and mechanisms. About half (51%) of respondent institutions reported having policies on research ethics and 58% had written policies requiring that researchers obtain informed consent of research participants. About one-third of respondent institutions (34%) had established ethics review committees, 42% required that studies went through ethics review committees and 46% had linkages with national or regional ethics organisations. Regarding operating procedures for ethics review committees, 53% had adopted standard operating procedures. Less than one-quarter of respondent institutions reported having policies in place to monitor ongoing research. Of the institutions that monitored ongoing research, 34% did an annual ethical review and 74% required a periodic written report. Only 36% provided any type of ethics training for staff, including those conducting health research and those who were not members of the ethics review committee. There are substantial gaps in the capacity of health research institutions in the WHO African Region to undertake ethical review of studies before, during and after studies conducted. There is a need to strengthen such capacity in order to ensure the wellbeing of individuals enrolled in studies and that of communities that host these studies. © The Royal Society of Medicine.

We describe two interim results from an ongoing effort to automate the acquisition, analysis, archiving, and distribution of satellite earth science data. Both results are applications of Artificial Intelligence planning research to the automatic generation of processing steps for image analysis tasks. First, we have constructed a linear conditional planner (CPed), used to generate conditional processing plans. Second, we have extended an existing hierarchical planning system to make use of durations, resources, and deadlines, thus supporting the automatic generation of processing steps in time and resource-constrained environments.

Guiding transcranial brain stimulation by EEG/MEG to interact with ongoing brain activity and associated functions: A position paper

Non-invasive transcranial brain stimulation (NTBS) techniques have a wide range of applications but also suffer from a number of limitations mainly related to poor specificity of intervention and variable effect size. These limitations motivated recent efforts to focus on the temporal dimension of NTBS with respect to the ongoing brain activity. Temporal patterns of ongoing neuronal activity, in particular brain oscillations and their fluctuations, can be traced with electro- or magnetoencephalography (EEG/MEG), to guide the timing as well as the stimulation settings of NTBS. These novel, online and offline EEG/MEG-guided NTBS-approaches are tailored to specifically interact with the underlying brain activity. Online EEG/MEG has been used to guide the timing of NTBS (i.e., when to stimulate): by taking into account instantaneous phase or power of oscillatory brain activity, NTBS can be aligned to fluctuations in excitability states. Moreover, offline EEG/MEG recordings prior to interventions can inform researchers and clinicians how to stimulate: by frequency-tuning NTBS to the oscillation of interest, intrinsic brain oscillations can be up- or down-regulated. In this paper, we provide an overview of existing approaches and ideas of EEG/MEG-guided interventions, and their promises and caveats. We point out potential future lines of research to address challenges. PMID:28233641

The design and development of a triaxial wear-testing joint simulator.

Green, A S; O'Connell, M K; Lyons, A S; James, S P

1999-01-01

Most of the existing wear testers created to wear test total hip replacements, specifically the acetabular component, are designed to exert only an axial force and provide rotation in a close approximation of the actual femoral movement. The Rocky Mountain Joint Simulator was designed to exert three orthogonal forces and provide rotations about the X-, Y- and Z-axes to more closely simulate the physiological forces and motions found in the human gait cycle. The RMJS was also designed with adaptability for other joints, such as knees or canine hips, through the use of hydraulics and a computer-programmable control system. Such adaptability and functionality allows the researcher to more closely model a gait cycle, thereby obtaining wear patterns that resemble those found in retrieved implants more closely than existing simulators. Research is ongoing into the tuning and evaluation of the machine and preliminary acetabular component wear test results will be presented at the conference.

EarthScope's Plate Boundary Observatory in Alaska: Building on Existing Infrastructure to Provide a Platform for Integrated Research and Hazard-monitoring Efforts

EarthScope's geodetic component in Alaska, the UNAVCO-operated Plate Boundary Observatory (PBO) network, includes 139 continuous GPS sites and 41 supporting telemetry relays. These are spread across a vast area, from northern AK to the Aleutians. Forty-five of these stations were installed or have been upgraded in cooperation with various partner agencies and currently provide data collection and transmission for more than one group. Leveraging existing infrastructure normally has multiple benefits, such as easier permitting requirements and costs savings through reduced overall construction and maintenance expenses. At some sites, PBO-AK power and communications systems have additional capacity beyond that which is needed for reliable acquisition of GPS data. Where permits allow, such stations could serve as platforms for additional instrumentation or real-time observing needs. With the expansion of the Transportable Array (TA) into Alaska, there is increased interest to leverage existing EarthScope resources for station co-location and telemetry integration. Because of the complexity and difficulty of long-term O&M at PBO sites, however, actual integration of GPS and seismic equipment must be considered on a case-by-case basis. UNAVCO currently operates two integrated GPS/seismic stations in collaboration with the Alaska Earthquake Center, and three with the Alaska Volcano Observatory. By the end of 2014, PBO and TA plan to install another four integrated and/or co-located geodetic and seismic systems. While three of these are designed around existing PBO stations, one will be a completely new TA installation, providing PBO with an opportunity to expand geodetic data collection in Alaska within the limited operations and maintenance phase of the project. We will present some of the design considerations, outcomes, and lessons learned from past and ongoing projects to integrate seismometers and other instrumentation at PBO-Alaska stations. Developing the PBO network as a platform for ongoing research and hazard monitoring equipment may also continue to serve the needs of the research community and the public beyond the sun-setting and completion of EarthScope science plan in 2018.

In its Energy Strategy 2050, Switzerland is revising its energy perspectives with a strong focus on renewable sources of energy and in particular hydropower. In this context, the Swiss Government funded a number of competence centers for energy research (SCCERs), including one on the Supply of Energy (SCCER-SoE), which develops fundamental research and innovative solutions in geoenergies and hydropower . Hydropower is already the major energy source in Switzerland, corresponding to approximately 55% of the total national electricity production (which was 69 TWh in 2014). The Energy Strategy 2050 foresees at least a net increase by 1.53 TWh/year in average hydrological conditions, in a context were almost all major river systems are already exploited and a straightforward application of recent environmental laws will impact (reduce) current hydropower production. In this contribution, we present the roadmap of the SCCER-SoE and an overview of our strategy to unravel currently non-exploited hydropower potential, in particular in river systems that are already used for hydropower production. The aim is hereby to quantify non-exploited natural flows, unnecessary water spills or storage volume deficits, whilst considering non-conventional approaches to water resources valuation and management. Such a better understanding of the current potential is paramount to justify future scenarios of adaptation of the existing hydropower infrastructure combining the increase of storage capacity with new connections between existing reservoirs, heightening or strengthening existing dams, increasing the operational volume of natural lakes (including new glacier lakes), or by building new dams. Tapping hidden potential shall also require operational changes to benefit from new flow patterns emerging under an evolving climate and in particular in the context of the ongoing glacier retreat. The paper shall present a broad view over the mentioned issues and first conclusions of ongoing research at the country scale.

But what will it Cost? The history of NASA cost estimating

Hamaker, Joseph W.

1994-01-01

Within two years of being chartered in 1958 as an independent agency to conduct civilian pursuits in aeronautics and space, NASA absorbed either wholly or partially the people, facilities, and equipment of several existing organizations. These included the laboratories of the National Advisory Committee of Aeronautics (NACA) at Langley Research Center in Virginia, Ames Research Center in California, and Lewis Research Center in Ohio; the Army Ballistic Missile Agency (ABMA) at Redstone Arsenal Alabama, for which the team of Wernher von Braun worked; and the Department of Defense Advanced Research Projects Agency (ARPA) and their ongoing work on big boosters. These were especially valuable resources to jump start the new agency in light of the shocking success of the Soviet space probe Sputnik in the autumn of the previous year and the corresponding pressure from an impatient American public to produce some response. Along with these inheritances, there came some existing systems engineering and management practices, including project cost estimating methodologies. This paper will briefly trace the origins of those methods and how they evolved within the agency over the past three decades.

Feasibility of using a knowledge-based system concept for in-flight primary flight display research

Ricks, Wendell R.

1991-01-01

A study was conducted to determine the feasibility of using knowledge-based systems architectures for inflight research of primary flight display information management issues. The feasibility relied on the ability to integrate knowledge-based systems with existing onboard aircraft systems. And, given the hardware and software platforms available, the feasibility also depended on the ability to use interpreted LISP software with the real time operation of the primary flight display. In addition to evaluating these feasibility issues, the study determined whether the software engineering advantages of knowledge-based systems found for this application in the earlier workstation study extended to the inflight research environment. To study these issues, two integrated knowledge-based systems were designed to control the primary flight display according to pre-existing specifications of an ongoing primary flight display information management research effort. These two systems were implemented to assess the feasibility and software engineering issues listed. Flight test results were successful in showing the feasibility of using knowledge-based systems inflight with actual aircraft data.

On-going collaborative priority-setting for research activity: a method of capacity building to reduce the research-practice translational gap.

International policy suggests that collaborative priority setting (CPS) between researchers and end users of research should shape the research agenda, and can increase capacity to address the research-practice translational gap. There is limited research evidence to guide how this should be done to meet the needs of dynamic healthcare systems. One-off priority setting events and time-lag between decision and action prove problematic. This study illustrates the use of CPS in a UK research collaboration called Collaboration and Leadership in Applied Health Research and Care (CLAHRC). Data were collected from a north of England CLAHRC through semi-structured interviews with 28 interviewees and a workshop of key stakeholders (n = 21) including academics, NHS clinicians, and managers. Documentary analysis of internal reports and CLAHRC annual reports for the first two and half years was also undertaken. These data were thematically coded. Methods of CPS linked to the developmental phase of the CLAHRC. Early methods included pre-existing historical partnerships with on-going dialogue. Later, new platforms for on-going discussions were formed. Consensus techniques with staged project development were also used. All methods demonstrated actual or potential change in practice and services. Impact was enabled through the flexibility of research and implementation work streams; 'matched' funding arrangements to support alignment of priorities in partner organisations; the size of the collaboration offering a resource to meet project needs; and the length of the programme providing stability and long term relationships. Difficulties included tensions between being responsive to priorities and the possibility of 'drift' within project work, between academics and practice, and between service providers and commissioners in the health services. Providing protected 'matched' time proved difficult for some NHS managers, which put increasing work pressure on them. CPS is more time consuming than traditional approaches to project development. CPS can produce needs-led projects that are bedded in services using a variety of methods. Contributing factors for effective CPS include flexibility in use and type of available resources, flexible work plans, and responsive leadership. The CLAHRC model provides a translational infrastructure that enables CPS that can impact on healthcare systems.

The Vision for Space Exploration marks the next segment of NASA's continuing journey to find answers to compelling questions about the origins of the solar system, the existence of life beyond Earth, and the ability of humankind to live on other worlds. The success of the Vision relies upon the ongoing research and development activities conducted at each of NASA's 10 field centers. In an effort to promote synergy across NASA as it works to meet its long-term goals, the Agency restructured its Strategic Enterprises into four Mission Directorates that align with the Vision. Consisting of Exploration Systems, Space Operations, Science, and Aeronautics Research, these directorates provide NASA Headquarters and the field centers with a streamlined approach to continue exploration both in space and on Earth.

Antifungal adjuvants: Preserving and extending the antifungal arsenal

PubMed Central

Butts, Arielle; Palmer, Glen E.; Rogers, P. David

2017-01-01

ABSTRACT As the rates of systemic fungal infections continue to rise and antifungal drug resistance becomes more prevalent, there is an urgent need for new therapeutic options. This issue is exacerbated by the limited number of systemic antifungal drug classes. However, the discovery, development, and approval of novel antifungals is an extensive process that often takes decades. For this reason, there is growing interest and research into the possibility of combining existing therapies with various adjuvants that either enhance activity or overcome existing mechanisms of resistance. Reports of antifungal adjuvants range from plant extracts to repurposed compounds, to synthetic peptides. This approach would potentially prolong the utility of currently approved antifungals and mitigate the ongoing development of resistance. PMID:27459018

Fetal tissue research: an ongoing story of professionally responsible success.

PubMed

Gelber, Shari E; McCullough, Laurence B; Chervenak, Frank A

2015-12-01

Therapies derived from fetal tissue research are some of the greatest success stories in medicine. Research using fetal tissue has allowed for development of vaccines for numerous diseases including polio, rubella, and measles. These vaccines have saved countless lives, improved quality of life, and decreased the need for induced abortion secondary to congenital infection. Research using cell lines derived from fetal tissue has assisted in better understanding disease pathogenesis and has served to produce human proteins as research reagents and therapies. Ongoing research points to the potential for fetal tissue to be used to cure debilitating diseases such as Parkinson disease. These scientific and medical advances are dependent on the use of fetal tissue from aborted fetuses. While the practice of induced abortion despite societal benefit may be theologically objectionable to some, these practices are professionally responsible. Federal regulations exist to discourage patients from being influenced by the societal benefit of fetal research in arriving at the decision to terminate as well as to prevent researchers from influencing a patient's decision. After a patient has chosen termination of pregnancy, it is consistent with professional responsibility to allow her to choose the disposition of the cadaveric fetal tissue. While some may view induced abortion and societal benefit from this practice as an ethical burden, the principle of justice makes it ethically obligatory to bear this ethical burden. The success story of cadaveric fetal tissue research and treatment should continue unhindered, to fulfill professional responsibility to current and future patients. Copyright © 2015 Elsevier Inc.

Purpose of Review To describe methodological challenges, gaps, and opportunities in U.S. transgender health research. Recent Findings Lack of large prospective observational studies and intervention trials, limited data on risks and benefits of gender affirmation (e.g., hormones and surgical interventions), and inconsistent use of definitions across studies hinder evidence-based care for transgender people. Systematic high-quality observational and intervention-testing studies may be carried out using several approaches, including general population-based, health systems-based, clinic-based, venue-based, and hybrid designs. Each of these approaches has its strength and limitations; however, harmonization of research efforts is needed. Ongoing development of evidence-based clinical recommendations will benefit from a series of observational and intervention studies aimed at identification, recruitment, and follow-up of transgender people of different ages, from different racial, ethnic, and socioeconomic backgrounds and with diverse gender identities. Summary Transgender health research faces challenges that include standardization of lexicon, agreed-upon population definitions, study design, sampling, measurement, outcome ascertainment, and sample size. Application of existing and new methods is needed to fill existing gaps, increase the scientific rigor and reach of transgender health research, and inform evidence-based prevention and care for this underserved population.

Skea, Zoë Christina; Treweek, Shaun; Gillies, Katie

2017-01-01

Objectives To explore trial site staff's perceptions regarding barriers and facilitators to local recruitment. Design Qualitative semi-structured interviews with a range of trial site staff from four trial sites in the UK. Interviews were analysed thematically to identify common themes across sites, barriers that could be addressed and facilitators that could be shared with other sites. Participants 11 members of staff from four trial sites: clinical grant Co-applicant (n=1); Principal Investigators (n=3); Consultant Urologist (n=1); Research Nurses (n=5); Research Assistant (n=1). Setting Embedded within an ongoing randomised controlled trial (the TISU trial). TISU is a UK multicentre trial comparing therapeutic interventions for ureteric stones. Results Our study draws attention to the initial and ongoing burden of trial work that is involved throughout the duration of a clinical trial. In terms of building and sustaining a research culture, trial staff described the ongoing work of engagement that was required to ensure that clinical staff were both educated and motivated to help with the process of identifying and screening potential participants. Having adequate and sufficient organisational and staffing resources was highlighted as being a necessary prerequisite to successful recruitment both in terms of accessing potentially eligible patients and being able to maximise recruitment after patient identification. The nature of the research study design can also potentially generate challenging communicative work for recruiting staff which can prove particularly problematic. Conclusions Our paper adds to existing research highlighting the importance of the hidden and complex work that is involved in clinical trial recruitment. Those designing and supporting the operationalisation of clinical trials must recognise and support the mitigation of this ‘work’. While much of the work is likely to be contextually sensitive at the level of local sites and for individual trials, some aspects are ubiquitous issues for delivery of trials more generally.

This is an artist's rendition of an antimatter propulsion system. Matter - antimatter arnihilation offers the highest possible physical energy density of any known reaction substance. It is about 10 billion times more powerful than that of chemical engergy such as hydrogen and oxygen combustion. Antimatter would be the perfect rocket fuel, but the problem is that the basic component of antimatter, antiprotons, doesn't exist in nature and has to manufactured. The process of antimatter development is on-going and making some strides, but production of this as a propulsion system is far into the future.

This paper describes the results of a cooperative study conducted by a team of researchers in formal methods at three NASA Centers to demonstrate FM techniques and to tailor them to critical NASA software systems. This pilot project applied FM to an existing critical software subsystem, the Shuttle's Jet Select subsystem (Phase I of an ongoing study). The present study shows that FM can be used successfully to uncover hidden issues in a highly critical and mature Functional Subsystem Software Requirements (FSSR) specification which are very difficult to discover by traditional means.

The National Science Foundation's (NSF) Research Experience for Undergraduates (REU) program provides undergraduate students with the opportunity to participate in ongoing scientific research. Existing either as stand-alone summer programs or as supplementary components to existing NSF research grants, the REU program focuses on introducing aspiring young scientists to the delights and complexities of science. Global Climate Change and Society (GCCS) is an intensive, 8-week REU program that began a 3-year run in the summer of 2001.Developed by a philosopher at the Colorado School of Mines, and a planetary scientist at Southwest Research Institute in Boulder, Colrado, GCCS is a unique experiment in research and pedagogy that introduces students to science by using a distinctive approach. Choosing as its topic the questions surrounding global climate change, the program explores the interwoven scientific, philosophical, and public policy issues that make the climate change debate such a volatile topic in contemporary society. Last summer, the program selected 12 undergraduates through a nationally advertised competition. Student interns came from diverse academic and cultural backgrounds and included physics, philosophy and public policy majors from elite liberal arts schools, major research institutions, and mainstream state universities. The program was held at the University of Colorado and the National Center for Atmospheric Research (NCAR), in Boulder, Colorado (Figure 1).

Past and Future Work on Radiobiology Mega-Studies: A Case Study At Argonne National Laboratory

2011-09-06

Between 1952 and 1992, more than 200 large radiobiology studies were conducted in research institutes throughout Europe, North America, and Japan to determine the effects of external irradiation and internal emitters on the lifespan and tissue toxicity development in animals. At Argonne National Laboratory, 22 external beam studies were conducted on nearly 700 beagle dogs and 50,000 mice between 1969 and 1992. These studies helped to characterize the effects of neutron and gamma irradiation on lifespan, tumorigenesis, and mutagenesis across a range of doses and dosing patterns. The records and tissues collected at Argonne during that time period have beenmore » carefully preserved and redisseminated. Using these archived data, ongoing statistical work has been done and continues to characterize quality of radiation, dose, dose rate, tissue, and gender-specific differences in the radiation responses of exposed animals. The ongoing application of newly-developed molecular biology techniques to the archived tissues has revealed gene-specific mutation rates following exposure to ionizing irradiation. The original and ongoing work with this tissue archive is presented here as a case study of a more general trend in the radiobiology megastudies. These experiments helped form the modern understanding of radiation responses in animals and continue to inform development of new radiation models. Recent archival efforts have facilitated open access to the data and materials produced by these studies, and so a unique opportunity exists to expand this continued research.« less

Hellstén, P; Nystén, T

2003-01-01

The migration of organic de-icers in the shallow aquifers typical in Finland is not well known and we need to find solutions to minimise the negative impacts of de-icing on groundwater quality. The objective of the MIDAS project is to find de-icers which have the least harmful impacts on groundwater quality. Migration of sodium chloride as a tracer and five alternative de-icers in aquifers was studied. The alternative de-icers were calcium chloride, magnesium chloride, calcium-magnesium-acetate, potassium acetate and potassium formate. The research consists of leaching of heavy metals from roadsides in the area of Highway 1 in southern Finland; an in vitro study, which represented the full length of winter at low temperatures; and the subsequent on-going field research in south-eastern Finland. So far, in our studies potassium formate caused fewer changes to the quality of the infiltrated water than the chlorides and acetates. After finishing the on-going research the results will be used to choose a preferred de-icer from the existing chemicals and for the development of new less harmful de-icers. The information will be used mainly in Scandinavia and North America where the hydrogeological conditions are similar to those in Finland.

Not in the mood? Men under- (not over-) perceive their partner's sexual desire in established intimate relationships.

2016-05-01

Men's sexual overperception bias-where men tend to perceive greater sexual interest in women's behavior than actually exists-is a well-documented finding in previous research. All of the existing research, however, has tested this effect in the context of initial encounters or for fictitious or unknown targets. No research currently exists on how people perceive their romantic partner's sexual desire in the context of ongoing, intimate relationships. In 3 dyadic studies, we provide evidence that men in established romantic relationships err in the direction of the opposite bias and underperceive their romantic partner's sexual desire. We also demonstrate that this underperception bias is functional (particularly for men) in that it is associated with their partner feeling more satisfied and committed to the relationship. In addition, people are particularly likely to underperceive their partner's desire on days when they are motivated to avoid sexual rejection, and men's underperception bias is, in part, accounted for by men's higher general levels of sexual desire than women. The current studies extend previous findings on sexual perceptual biases and demonstrate the important role of context in men's judgments of a partner's sexual interest.

The current challenges of instrumentation technology are to further develop systems packaging and component testing of specialized sensors, further develop instrumentation techniques on complex surfaces, improve sensor durability, and to address needs for extreme temperature applications. The technology research and development ongoing at NASA Glenn for applications to future launch vehicles, space vehicles, and ground systems is outlined.

Health disparities: a primer for public health social workers.

PubMed

Keefe, Robert H

2010-05-01

In 2001, the U.S. Department of Health and Human Services published Healthy People 2010, which identified objectives to guide health promotion and to eliminate health disparities. Since 2001, much research has been published documenting racial and ethnic disparities in healthcare. Although progress has been made in eliminating the disparities, ongoing work by public health social workers, researchers, and policy analysts is needed. This paper focuses on racial and ethnic health disparities, why they exist, where they can be found, and some of the key health/medical conditions identified by the U.S. Department of Health and Human Services to receive attention. Finally, there is a discussion of what policy, professional and community education, and research can to do to eliminate racial and ethnic disparities in healthcare.

The goals of the current study were to expand the content domain and further validate the Coercion Assessment Scale (CAS), a measure of perceived coercion for criminally involved substance abusers being recruited into research. Unlike the few existing measures of this construct, the CAS identifies specific external sources of pressure that may influence one's decision to participate. In Phase 1, we conducted focus groups with criminal justice clients and stakeholders to expand the instrument by identifying additional sources of pressure. In Phase 2, we evaluated the expanded measure (i.e., endorsement rates, reliability, validity) in an ongoing research trial. Results identified new sources of pressure and provided evidence supporting the CAS's utility and reliability over time as well as convergent and discriminative validity. © The Author(s) 2014.

Researcher-initiated biobanks based at academic institutions contribute valuable biomarker and translational research advances to medicine. With many legacy banks once supported by federal funding, reductions in fiscal support threaten the future of existing and new biobanks. When the Brain Bank at Duke University's Bryan Alzheimer's Disease Center (ADRC) faced a funding crisis, a collaborative, multidisciplinary team embarked on a 2-year biobank sustainability project utilizing a comprehensive business strategy, dedicated project management, and a systems approach involving many Duke University entities. By synthesizing and applying existing knowledge, Duke Translational Medicine Institute created and launched a business model that can be adjusted and applied to legacy and start-up academic biobanks. This model provides a path to identify new funding mechanisms, while also emphasizing improved communication, business development, and a focus on collaborating with industry to improve access to biospecimens. Benchmarks for short-term Brain Bank stabilization have been successfully attained, and the evaluation of long-term sustainability metrics is ongoing. © 2015 Wiley Periodicals, Inc.

Development of an Experiment High Performance Nozzle Research Program

NASA Technical Reports Server (NTRS)

2004-01-01

As proposed in the above OAI/NASA Glenn Research Center (GRC) Co-Operative Agreement the objective of the work was to provide consultation and assistance to the NASA GRC GTX Rocket Based Combined Cycle (RBCC) Program Team in planning and developing requirements, scale model concepts, and plans for an experimental nozzle research program. The GTX was one of the launch vehicle concepts being studied as a possible future replacement for the aging NASA Space Shuttle, and was one RBCC element in the ongoing NASA Access to Space R&D Program (Reference 1). The ultimate program objective was the development of an appropriate experimental research program to evaluate and validate proposed nozzle concepts, and thereby result in the optimization of a high performance nozzle for the GTX launch vehicle. Included in this task were the identification of appropriate existing test facilities, development of requirements for new non-existent test rigs and fixtures, develop scale nozzle model concepts, and propose corresponding test plans. Also included were the evaluation of originally proposed and alternate nozzle designs (in-house and contractor), evaluation of Computational Fluid Dynamics (CFD) study results, and make recommendations for geometric changes to result in improved nozzle thrust coefficient performance (Cfg).

Research on the cognitively impaired: lessons and warnings from the emergency research debate.

Karlawish, J H; Sachs, G A

1997-04-01

To demonstrate that the recent events in emergency research have broad implications for the conduct of human subjects research with the cognitively impaired. This essay illustrates the similarities between the two kinds of research and suggests how understanding these similarities might help to resolve issues in human subjects research on the cognitively impaired. A review of pertinent journal articles, books, regulations, and court cases. The emergency research controversy resulted in large part because of conflicting interpretations of arguably inadequate research regulations. The proposed Food and Drug Administration (FDA) regulations include advance informed consent, a broad role for family in approving a subject's participation, replacement of a threshold of permissible risk, called minimal risk, with a more sensible balancing of risks and benefits, and a role for the community in research approval. The current state of research on the cognitively impaired suggests that many of the same problems exist now that existed in emergency research before the FDA issued its proposed regulations. The ongoing case of T.D. et al. vs N.Y. State Office of Mental Health suggest that unless steps are taken similar to those taken in emergency research, much of clinical research on the cognitively impaired could cease. Representatives of the government, medicine, and the public must recognize the unresolved issues and inadequate regulations relating to research on the cognitively impaired. The proposed FDA regulations for emergency research may provide guidance for a settlement of these issues.

On Modeling Research Work for Describing and Filtering Scientific Information

NASA Astrophysics Data System (ADS)

Sicilia, Miguel-Ángel

Existing models for Research Information Systems (RIS) properly address the description of people and organizations, projects, facilities and their outcomes, e.g. papers, reports or patents. While this is adequate for the recording and accountability of research investments, helping researchers in finding relevant people, organizations or results requires considering both the content of research work and also its context. The content is not only related to the domain area, but it requires modeling methodological issues as variables, instruments or scientific methods that can then be used as search criteria. The context of research work is determined by the ongoing projects or scientific interests of an individual or a group, and can be expressed using the same methodological concepts. However, modeling methodological issues is notably complex and dependent on the scientific discipline and research area. This paper sketches the main requirements for those models, providing some motivating examples that could serve as a point of departure for future attempts in developing an upper ontology for research methods and tools.

PURPOSE. Although in the last decades primary care research has evolved with great success, there is a growing need to prioritize the topics given the limited resources available. Therefore, we constructed a nationwide database of ongoing primary care research projects in the Netherlands, and we assessed if the distribution of research topics matched with primary care practice. We conducted a survey among the main primary care research centres in the Netherlands and gathered details of all ongoing primary care research projects. We classified the projects according to research topic, relation to professional guidelines and knowledge deficits, collaborative partners and funding source. Subsequently, we compared the frequency distribution of clinical topics of research projects to the prevalence of problems in primary care practice. We identified 296 ongoing primary care research projects from 11 research centres. Most projects were designed as randomized controlled trial (35%) or observational cohort (34%), and government funded mostly (60%). Thematically, most research projects addressed chronic diseases, mainly cardiovascular risk management (8%), depressive disorders (8%) and diabetes mellitus (7%). One-fifth of the projects was related to defined knowledge deficits in primary care guidelines. From a clinical primary care perspective, research projects on dermatological problems were significantly underrepresented (P = 0.01). This survey of ongoing projects demonstrates that primary care research has a firm basis in the Netherlands, with a strong focus on chronic disease. The fit with primary care practice can improve, and future research should address knowledge deficits in professional guidelines more.

Electronic document distribution: Design of the anonymous FTP Langley Technical Report Server

Nelson, Michael L.; Gottlich, Gretchen L.

1994-01-01

An experimental electronic dissemination project, the Langley Technical Report Server (LTRS), has been undertaken to determine the feasibility of delivering Langley technical reports directly to the desktops of researchers worldwide. During the first six months, over 4700 accesses occurred and over 2400 technical reports were distributed. This usage indicates the high level of interest that researchers have in performing literature searches and retrieving technical reports at their desktops. The initial system was developed with existing resources and technology. The reports are stored as files on an inexpensive UNIX workstation and are accessible over the Internet. This project will serve as a foundation for ongoing projects at other NASA centers that will allow for greater access to NASA technical reports.

An extensive literature search was conducted and those experiments related to unsteady boundary layer behavior were cataloged. In addition, an international survey of industrial, university, and governmental research laboratories was made in which new and ongoing experimental programs associated with unsteady turbulent boundary layer research were identified. Pertinent references were reviewed and classified based on the technical emphasis of the various experiments. Experiments that include instantaneous or ensemble averaged profiles of boundary layer variables are stressed. The experimental apparatus and flow conditions are described and summaries of acquired data and significant conclusions are summarized. Measurements obtained from the experiments which exist in digital form were stored on magnetic tape. Instructions are given for accessing these data sets for further analysis.

The cannabis plant and its active ingredients (i.e., cannabinoids and terpenoids) have been socially stigmatized for half a century. Luckily, with more than 430,000 published scientific papers and about 600 ongoing and completed clinical trials, nowadays cannabis is employed for the treatment of many different medical conditions. Nevertheless, even if a large amount of high-throughput functional genomic data exists, most researchers feature a strong background in molecular biology but lack advanced bioinformatics skills. In this work, publicly available gene expression datasets have been analyzed giving rise to a total of 40,224 gene expression profiles taken from cannabis plant tissue at different developmental stages. The resource presented here will provide researchers with a starting point for future investigations with Cannabis sativa .

Cannabis is available from medical dispensaries for treating posttraumatic stress disorder (PTSD) in many states of the union, yet its efficacy in treating PTSD symptoms remains uncertain. To identify ongoing studies and review existing evidence regarding the benefits and harms of plant-based cannabis preparations in treating PTSD in adults. MEDLINE, the Cochrane Library, and other sources from database inception to March 2017. English-language systematic reviews, trials, and observational studies with a control group that reported PTSD symptoms and adverse effects of plant-based cannabis use in adults with PTSD. Study data extracted by 1 investigator was checked by a second reviewer; 2 reviewers independently assessed study quality, and the investigator group graded the overall strength of evidence by using standard criteria. Two systematic reviews, 3 observational studies, and no randomized trials were found. The systematic reviews reported insufficient evidence to draw conclusions about benefits and harms. The observational studies found that compared with nonuse, cannabis did not reduce PTSD symptoms. Studies had medium and high risk of bias, and overall evidence was judged insufficient. Two randomized trials and 6 other studies examining outcomes of cannabis use in patients with PTSD are ongoing and are expected to be completed within 3 years. Very scant evidence with medium to high risk of bias. Evidence is insufficient to draw conclusions about the benefits and harms of plant-based cannabis preparations in patients with PTSD, but several ongoing studies may soon provide important results.

Although the diagnosis of AD can be devastating, treatment options exist that can slow the disease's progression and allow patients to continue performing ADLs, thereby improving the quality of life for both patient and caregiver. Research is ongoing, and it is estimated by the Alzheimer's Association that finding a treatment that could delay onset by only 5 years could reduce the number of individuals with AD by nearly 50% over the next 50 years (Alzheimer's Association, 2007). Although pharmacotherapy is not yet a cure, it does remain an important part of a total approach to caring for patients and families affected by AD.

A Markov Chain-based quantitative study of angular distribution of photons through turbid slabs via isotropic light scattering

Li, Xuesong; Northrop, William F.

2016-04-01

This paper describes a quantitative approach to approximate multiple scattering through an isotropic turbid slab based on Markov Chain theorem. There is an increasing need to utilize multiple scattering for optical diagnostic purposes; however, existing methods are either inaccurate or computationally expensive. Here, we develop a novel Markov Chain approximation approach to solve multiple scattering angular distribution (AD) that can accurately calculate AD while significantly reducing computational cost compared to Monte Carlo simulation. We expect this work to stimulate ongoing multiple scattering research and deterministic reconstruction algorithm development with AD measurements.

The field of paper-based microfluidics has experienced rapid growth over the past decade. Microfluidic paper-based analytical devices (μPADs), originally developed for point-of-care medical diagnostics in resource-limited settings, are now being applied in new areas, such as environmental analyses. Low-cost paper sensors show great promise for on-site environmental analysis; the theme of ongoing research complements existing instrumental techniques by providing high spatial and temporal resolution for environmental monitoring. This review highlights recent applications of μPADs for environmental analysis along with technical advances that may enable μPADs to be more widely implemented in field testing.

Ontologies describe reality in specific domains in ways that can bridge various disciplines and languages. They allow easier access and integration of information that is collected by different groups. Ontologies are currently used in the biomedical sciences, geography, and law. A Biomedical Ethics Ontology (BMEO) would benefit members of ethics committees who deal with protocols and consent forms spanning numerous fields of inquiry. There already exists the Ontology for Biomedical Investigations (OBI); the proposed BMEO would interoperate with OBI, creating a powerful information tool. We define a domain ontology and begin to construct a BMEO, focused on the process of evaluating human research protocols. Finally, we show how our BMEO can have practical applications for ethics committees. This paper describes ongoing research and a strategy for its broader continuation and cooperation. PMID:19374479

Developing a quantitative understanding of the biogeochemical cycles of carbon as they have worked throughout Earth history on various time scales, how they have been affected by biological evolution, and how changes in the carbon content of ocean and atmosphere may have affected climate and the evolution of life are the goals of the research. Theoretical simulations were developed that can be tuned to reproduce such data as exist and, once tuned, can be used to predict properties that have not yet been observed. This is an ongoing process, in which models and results are refined as new data and interpretations become available and as understanding of the global system improves. Results of the research are described in several papers which were published or submitted for publication. These papers are summarized. Future research plans are presented.

In June 1996, the National Research Council (NRC) formed the Committee on Major U.S. Oceanographic Research Programs to foster coordination among the large programs (e.g., World Ocean Circulation Experiment, Ocean Drilling Program, Ridge Interdisciplinary Global Experiment, and others) and examine their role in ocean research. In particular, the committee is charged with (1) enhancing information sharing and the coordinated implementation of the research plans of the major ongoing and future programs; (2) assisting the federal agencies and ocean sciences community in identifying gaps, as well as appropriate followon activities to existing programs; (3) making recommendations on how future major ocean programs should be planned, structured and organized; and (4) evaluating the impact of major ocean programs on the understanding of the oceans, development of research facilities, education, and collegiality in the academic community. The activity was initiated at the request of the National Science Foundation (NSF) Division of Ocean Sciences, is overseen by the NRC's Ocean Studies Board (OSB), and is funded by both NSF and the Office of Naval Research.

Increased interest in the potential societal benefit of incorporating health economics as a part of clinical translational science, particularly nutrition interventions, led the Office of Dietary Supplements at the National Institutes of Health to sponsor a conference to address key questions about economic analysis of nutrition interventions to enhance communication among health economic methodologists, researchers, reimbursement policy makers, and regulators. Issues discussed included the state of the science, such as what health economic methods are currently used to judge the burden of illness, interventions, or health care policies, and what new research methodologies are available or needed to address knowledge and methodological gaps or barriers. Research applications included existing evidence-based health economic research activities in nutrition that are ongoing or planned at federal agencies. International and U.S. regulatory, policy and clinical practice perspectives included a discussion of how research results can help regulators and policy makers within government make nutrition policy decisions, and how economics affects clinical guideline development.

Service learning and study abroad opportunities have become increasingly popular in nursing education in the past decade. The purpose of this systematic review was to explore existing literature concerning global health experiences in nursing education. Twenty-three empirical articles from 2003 to 2010 were reviewed, building upon existing reviews of international nursing education literature. Research on two-way exchange experiences and models for best practice were found to be lacking. While an array of countries were represented as the visiting or hosting side of the experience, few co-authors from host countries were found, particularly in literature originating from the U.S. The authors recommend that two-way exchange programs be evaluated to identify successful strategies and barriers to success. Ongoing evaluation of exchanges is necessary to ensure continued sustainable partnership and exchange in immersion experiences for nursing students.

A Research Roadmap for Computation-Based Human Reliability Analysis

2015-08-01

The United States (U.S.) Department of Energy (DOE) is sponsoring research through the Light Water Reactor Sustainability (LWRS) program to extend the life of the currently operating fleet of commercial nuclear power plants. The Risk Informed Safety Margin Characterization (RISMC) research pathway within LWRS looks at ways to maintain and improve the safety margins of these plants. The RISMC pathway includes significant developments in the area of thermalhydraulics code modeling and the development of tools to facilitate dynamic probabilistic risk assessment (PRA). PRA is primarily concerned with the risk of hardware systems at the plant; yet, hardware reliability is oftenmore » secondary in overall risk significance to human errors that can trigger or compound undesirable events at the plant. This report highlights ongoing efforts to develop a computation-based approach to human reliability analysis (HRA). This computation-based approach differs from existing static and dynamic HRA approaches in that it: (i) interfaces with a dynamic computation engine that includes a full scope plant model, and (ii) interfaces with a PRA software toolset. The computation-based HRA approach presented in this report is called the Human Unimodels for Nuclear Technology to Enhance Reliability (HUNTER) and incorporates in a hybrid fashion elements of existing HRA methods to interface with new computational tools developed under the RISMC pathway. The goal of this research effort is to model human performance more accurately than existing approaches, thereby minimizing modeling uncertainty found in current plant risk models.« less

Loads and loads and loads: the influence of prospective load, retrospective load, and ongoing task load in prospective memory.

PubMed

Meier, Beat; Zimmermann, Thomas D

2015-01-01

In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load (OTL) can affect prospective memory performance. The existence of multiple target events increases prospective load (PL) and adding complexity to the to-be-remembered action increases retrospective load (RL). In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of PL on costs in the ongoing task for categorical targets (Experiment 2), but not for specific targets (Experiment 1). RL and OTL both affected remembering the retrospective component of the prospective memory task. We suggest that PL can enhance costs in the ongoing task due to additional monitoring requirements. RL and OTL seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially.

A recent mixed-methods study on the state of emergency medical services (EMS) research in Canada led to the generation of nineteen actionable recommendations. As part of the dissemination plan, a survey was distributed to EMS stakeholders to determine the anticipated impact and feasibility of implementing these recommendations in Canadian systems. An online survey explored both the implementation impact and feasibility for each recommendation using a five-point scale. The sample consisted of participants from the Canadian National EMS Research Agenda study (published in 2013) and additional EMS research stakeholders identified through snowball sampling. Responses were analysed descriptively using median and plotted on a matrix. Participants reported any planned or ongoing initiatives related to the recommendations, and required or anticipated resources. Free text responses were analysed with simple content analysis, collated by recommendation. The survey was sent to 131 people, 94 (71.8%) of whom responded: 30 EMS managers/regulators (31.9%), 22 researchers (23.4%), 15 physicians (16.0%), 13 educators (13.8%), and 5 EMS providers (5.3%). Two recommendations (11%) had a median impact score of 4 (of 5) and feasibility score of 4 (of 5). Eight recommendations (42%) had an impact score of 5, with a feasibility score of 3. Nine recommendations (47%) had an impact score of 4 and a feasibility score of 3. For most recommendations, participants scored the anticipated impact higher than the feasibility to implement. Ongoing or planned initiatives exist pertaining to all recommendations except one. All of the recommendations will require additional resources to implement.

The recent proliferation of strategies designed to increase the use of research in health policy (knowledge exchange) demands better application of contemporary conceptual understandings of how research shapes policy. Predictive models, or action frameworks, are needed to organise existing knowledge and enable a more systematic approach to the selection and testing of intervention strategies. Useful action frameworks need to meet four criteria: have a clearly articulated purpose; be informed by existing knowledge; provide an organising structure to build new knowledge; and be capable of guiding the development and testing of interventions. This paper describes the development of the SPIRIT Action Framework. A literature search and interviews with policy makers identified modifiable factors likely to influence the use of research in policy. An iterative process was used to combine these factors into a pragmatic tool which meets the four criteria. The SPIRIT Action Framework can guide conceptually-informed practical decisions in the selection and testing of interventions to increase the use of research in policy. The SPIRIT Action Framework hypothesises that a catalyst is required for the use of research, the response to which is determined by the capacity of the organisation to engage with research. Where there is sufficient capacity, a series of research engagement actions might occur that facilitate research use. These hypotheses are being tested in ongoing empirical work.

2017-08-11

To explore trial site staff's perceptions regarding barriers and facilitators to local recruitment. Qualitative semi-structured interviews with a range of trial site staff from four trial sites in the UK. Interviews were analysed thematically to identify common themes across sites, barriers that could be addressed and facilitators that could be shared with other sites. 11 members of staff from four trial sites: clinical grant Co-applicant (n=1); Principal Investigators (n=3); Consultant Urologist (n=1); Research Nurses (n=5); Research Assistant (n=1). Embedded within an ongoing randomised controlled trial (the TISU trial). TISU is a UK multicentre trial comparing therapeutic interventions for ureteric stones. Our study draws attention to the initial and ongoing burden of trial work that is involved throughout the duration of a clinical trial. In terms of building and sustaining a research culture, trial staff described the ongoing work of engagement that was required to ensure that clinical staff were both educated and motivated to help with the process of identifying and screening potential participants. Having adequate and sufficient organisational and staffing resources was highlighted as being a necessary prerequisite to successful recruitment both in terms of accessing potentially eligible patients and being able to maximise recruitment after patient identification. The nature of the research study design can also potentially generate challenging communicative work for recruiting staff which can prove particularly problematic. Our paper adds to existing research highlighting the importance of the hidden and complex work that is involved in clinical trial recruitment. Those designing and supporting the operationalisation of clinical trials must recognise and support the mitigation of this 'work'. While much of the work is likely to be contextually sensitive at the level of local sites and for individual trials, some aspects are ubiquitous issues for delivery of trials more generally.

2014-09-01

Research outputs increase inexorably. Health is now a required element in all policies of the European Union. There is a need for a system that helps to navigate the vast body of children's health research, identify pertinent research institutions, discover ongoing and recently funded research projects and identify gaps where there is little knowledge. The European Commission funded the Research Inventory of Child Health in Europe (RICHE) project through the Framework 7 Programme, to identify gaps in child health research in Europe. A necessary first step was to identify and index current research, for which a website repository was created. As a basis for this task, an innovative taxonomy was necessary to encompass the many arenas of children's health and development, including subjects outside the traditional areas of children's health. Drawing inspiration from existing taxonomies, library systems and other forms of classification, a multi-axial approach was selected as the best way to encompass the many influences on children's health. Six axes were identified and their contents defined. All of the axes can be viewed and searched independently, as well as in relation to each other. The axes encompass factors and service areas that impact on children, including health, education, justice, the environment and others. This has created a system that is consistent and impartial, but adaptable to an enormous variety of uses. The taxonomy has been tested and validated by a number of well-respected academics, researchers and practitioners across Europe. It forms the basis of an intuitive and accessible database. This allows research knowledge to be easily identified and for networking to take place. The RICHE taxonomy facilitates retrieval of knowledge - ongoing research as well as findings - in order to inform researchers and policy makers who wish to include children's health as an element of new policy. © 2013 John Wiley & Sons Ltd.

In recent years, fiber Bragg gratings (FBGs) are becoming increasingly attractive for sensing applications in biomechanics and rehabilitation engineering due to their advantageous properties like small size, light weight, biocompatibility, chemical inertness, multiplexing capability and immunity to electromagnetic interference (EMI). They also offer a high-performance alternative to conventional technologies, either for measuring a variety of physical parameters or for performing high-sensitivity biochemical analysis. FBG-based sensors demonstrated their feasibility for specific sensing applications in aeronautic, automotive, civil engineering structure monitoring and undersea oil exploration; however, their use in the field of biomechanics and rehabilitation applications is very recent and its practicality for full-scale implementation has not yet been fully established. They could be used for detecting strain in bones, pressure mapping in orthopaedic joints, stresses in intervertebral discs, chest wall deformation, pressure distribution in Human Machine Interfaces (HMIs), forces induced by tendons and ligaments, angles between body segments during gait, and many others in dental biomechanics. This article aims to provide a comprehensive overview of all the possible applications of FBG sensing technology in biomechanics and rehabilitation and the status of ongoing researches up-to-date all over the world, demonstrating the FBG advances over other existing technologies.

From in vivo to in vitro: How the Guatemala STD Experiments Transformed Bodies Into Biospecimens.

PubMed

Spector-Bagdady, Kayte; Lombardo, Paul A

2018-06-01

Policy Points: While most scholarship regarding the US Public Health Service's STD experiments in Guatemala during the 1940s has focused on the intentional exposure experiments, secondary research was also conducted on biospecimens collected from these subjects. These biospecimen experiments continued after the Guatemala grant ended, and the specimens were used in conjunction with those from the Tuskegee syphilis experiments for ongoing research. We argue there should be a public accounting of whether there are still biospecimens from the Guatemala and Tuskegee experiments held in US government biorepositories today. If such specimens exist, they should be retired from US government research archives because they were collected unethically as understood at the time. The US Public Health Service's Guatemala STD experiments (1946-1948) included intentional exposure to pathogens and testing of postexposure prophylaxis methods for syphilis, gonorrhea, and chancroid in over 1,300 soldiers, commercial sex workers, prison inmates, and psychiatric patients. Though the experiments had officially ended, the biospecimens collected from these subjects continued to be used for research at least into the 1950s. We analyzed historical documents-including clinical and laboratory records, correspondence, final reports, and medical records-for information relevant to these biospecimen experiments from the US National Archives. In addition, we researched material from past governmental investigations into the Guatemala STD experiments, including those of the US Presidential Commission for the Study of Bioethical Issues and the Guatemalan Comisión Presidencial para el Esclarecimiento de los Experimentos Practicados con Humanos en Guatemala. Identified spinal fluid, blood specimens, and tissue collected during the Guatemala diagnostic methodology and intentional exposure experiments were subsequently distributed to laboratories throughout the United States for use in ongoing research until at least 1957. Five psychiatric patient subjects involved in these biospecimen experiments died soon after experimental exposure to STDs. The same US government researchers working with the Guatemala biospecimens after the exposure experiments ended were also working with specimens taken from the Tuskegee syphilis study. There should be a complete public accounting of whether biospecimens from the Guatemala and Tuskegee experiments are held in US government biorepositories today. If they still exist, these specimens should be retired from such biorepositories and their future disposition determined by stakeholders, including representatives from the communities from which they were derived. © 2018 Milbank Memorial Fund.

Understanding and managing the food-energy-water nexus - opportunities for water resources research

NASA Astrophysics Data System (ADS)

Cai, Ximing; Wallington, Kevin; Shafiee-Jood, Majid; Marston, Landon

2018-01-01

Studies on the food, energy, and water (FEW) nexus lay a shared foundation for researchers, policy makers, practitioners, and stakeholders to understand and manage linked production, utilization, and security of FEW systems. The FEW nexus paradigm provides the water community specific channels to move forward in interdisciplinary research where integrated water resources management (IWRM) has fallen short. Here, we help water researchers identify, articulate, utilize, and extend our disciplinary strengths within the broader FEW communities, while informing scientists in the food and energy domains about our unique skillset. This paper explores the relevance of existing and ongoing scholarship within the water community, as well as current research needs, for understanding FEW processes and systems and implementing FEW solutions through innovations in technologies, infrastructures, and policies. Following the historical efforts in IWRM, hydrologists, water resources engineers, economists, and policy analysts are provided opportunities for interdisciplinary studies among themselves and in collaboration with energy and food communities, united by a common path to achieve sustainability development goals.

Schuster, David M.; Scott, Robert C.; Bartels, Robert E.; Edwards, John W.; Bennett, Robert M.

2000-01-01

As computational fluid dynamics methods mature, code development is rapidly transitioning from prediction of steady flowfields to unsteady flows. This change in emphasis offers a number of new challenges to the research community, not the least of which is obtaining detailed, accurate unsteady experimental data with which to evaluate new methods. Researchers at NASA Langley Research Center (LaRC) have been actively measuring unsteady pressure distributions for nearly 40 years. Over the last 20 years, these measurements have focused on developing high-quality datasets for use in code evaluation. This paper provides a sample of unsteady pressure measurements obtained by LaRC and available for government, university, and industry researchers to evaluate new and existing unsteady aerodynamic analysis methods. A number of cases are highlighted and discussed with attention focused on the unique character of the individual datasets and their perceived usefulness for code evaluation. Ongoing LaRC research in this area is also presented.

Enhancing citizens’ and communities’ resilience is critical to adapt successfully to ongoing challenges faced by communities, as well as acute shocks resulting from disasters. While significant progress has been made in this area, several research and practice gaps remain. A crucial next step to advance resilience is the development of a resilience-oriented workforce. This narrative review examines existing literature to determine key components of a resilience-oriented workforce, with a focus on organizational structures, training and education, and leadership models. Reviewed articles spanned a variety of study types, including needs assessments of existing workforce, program evaluations, and reviews/commentaries. A resilience-oriented workforce spans many disciplines and training programs will need to reflect that. It requires a collaborative organizational model that promotes information sharing structures. Leadership models should foster a balance between workforce autonomy and operation as a collective entity. Optimal strategies to develop a resilience-oriented workforce have yet to be realized and future research will need to collect and synthesize data to promote and evaluate the growth of this field.

Clinical Trials Infrastructure as a Quality Improvement Intervention in Low- and Middle-Income Countries.

PubMed

Denburg, Avram; Rodriguez-Galindo, Carlos; Joffe, Steven

2016-06-01

Mounting evidence suggests that participation in clinical trials confers neither advantage nor disadvantage on those enrolled. Narrow focus on the question of a "trial effect," however, distracts from a broader mechanism by which patients may benefit from ongoing clinical research. We hypothesize that the existence of clinical trials infrastructure-the organizational culture, systems, and expertise that develop as a product of sustained participation in cooperative clinical trials research-may function as a quality improvement lever, improving the quality of care and outcomes of all patients within an institution or region independent of their individual participation in trials. We further contend that this "infrastructure effect" can yield particular benefits for patients in low- and middle-income countries (LMICs). The hypothesis of an infrastructure effect as a quality improvement intervention, if correct, justifies enhanced research capacity in LMIC as a pillar of health system development.

Magnetohydrodynamic Turbulence and the Geodynamo

NASA Technical Reports Server (NTRS)

Shebalin, John V.

2014-01-01

The ARES Directorate at JSC has researched the physical processes that create planetary magnetic fields through dynamo action since 2007. The "dynamo problem" has existed since 1600, when William Gilbert, physician to Queen Elizabeth I, recognized that the Earth was a giant magnet. In 1919, Joseph Larmor proposed that solar (and by implication, planetary) magnetism was due to magnetohydrodynamics (MHD), but full acceptance did not occur until Glatzmaier and Roberts solved the MHD equations numerically and simulated a geomagnetic reversal in 1995. JSC research produced a unique theoretical model in 2012 that provided a novel explanation of these physical observations and computational results as an essential manifestation of broken ergodicity in MHD turbulence. Research is ongoing, and future work is aimed at understanding quantitative details of magnetic dipole alignment in the Earth as well as in Mercury, Jupiter and its moon Ganymede, Saturn, Uranus, Neptune, and the Sun and other stars.

In the past couple of years, there has been a growing focus on the need to make scientific output accessible to a greater number of people, especially in the field of clinical research. The public are being urged to become more well-informed and to ask their doctors about taking part in clinical trials. A key finding of a report from the Association of Medical Research Charities was that all published scientific papers would benefit from having a section in plain English. Researchers running a clinical trial are expected to provide a summary of their intended research at various stages of the research process. However, there is evidence that existing summaries are of variable length and quality and not always in plain English. As a result, the National Institute for Health Research (NIHR) commissioned a review of the guidance that is available to researchers. However, recent initiatives demonstrate that there are still a number of challenges in making current research both accessible and understandable by prospective participants. BioMed Central also has a number of ongoing initiatives involving trial registration services and journals.

When the Government of Ontario launched a comprehensive mental health and addictions strategy, the Institute for Clinical Evaluative Sciences (ICES) was tasked with developing a scorecard for ongoing monitoring of the child and youth mental health system. Using existing administrative and survey-based healthcare and education data, researchers at ICES developed a scorecard consisting of 25 indicators that described at-risk populations, child and youth mental healthcare and relevant outcomes. This scorecard is the first in Canada to report on performance indicators for the child and youth mental health system and provides a model for monitoring child and youth mental health using routinely collected administrative data.

A large gap exists between the completion of clinical research demonstrating the benefit of new treatment interventions and improved patient outcomes resulting from implementation of these interventions as part of routine clinical practice. This gap clearly affects patient safety and quality of care. Knowledge translation is important for addressing this gap, but evaluation of the most appropriate and effective knowledge translation methods is still ongoing. Through describing one model for knowledge translation and an example of its implementation, insights can be gained into systematic methods for advancing the implementation of evidence-based interventions to improve safety, quality, and patient outcomes.

The quantum theory of time, the block universe, and human experience

2018-01-01

Advances in our understanding of the physical universe have dramatically affected how we view ourselves. Right at the core of all modern thinking about the universe is the assumption that dynamics is an elemental feature that exists without question. However, ongoing research into the quantum nature of time is challenging this view: my recently introduced quantum theory of time suggests that dynamics may be a phenomenological consequence of a fundamental violation of time reversal symmetry. I show here that there is consistency between the new theory and the block universe view. I also discuss the new theory in relation to the human experience of existing in the present moment, able to reflect on the past and contemplate a future that is yet to happen.

In recent decades, scientists have observed and documented impacts from climate change that will impact multiple sectors, will be impacted by decisions from multiple sectors, and will change over time. This complex human-engineered system has a large number of moving, interacting parts, which are interdependent and evolve over time towards their purpose. Many of the existing resilience frameworks and vulnerability frameworks focus on interactions between the domains, but do not include the structure of the interactions. We present an engineering systems approach to investigate the structural elements that influence a community's ability to be resilient. In this presentation we will present and analyze four common methods for building community resilience, utilizing our common framework. For several existing case studies we examine the stress points in the system and identify the impacts on the outcomes from the case studies. In ongoing research we will apply our system tool to a new case in the field.

The current Ebola Virus Disease (EVD) outbreak in West Africa is the largest in history. As of February 18(th) 2015, 23,258 cases of EVD have been cumulatively reported from Nigeria, Senegal, Guinea, Liberia, Mali, Sierra Leone, Spain, the United Kingdom and the United States of America resulting in more than 9,000 deaths. It is therefore exigent to develop prevention and treatment therapies for EVD. Several new EVD treatments are in clinical development at this time. Based on lessons learned, four critical processes need to be implemented before clinical trials begin. First, all global EVD research need to be coordinated to promote data sharing and synergistic overlap, while reducing unnecessary duplication of efforts. The World Health Organization is well-placed to undertake such an endeavor. Second, governments of affected nations where trials are being proposed need to lead discussions regarding immediate access to any proven medications for epidemics. Also, governments need to leverage international resources to support and expand existing national expertise to jointly conduct high-caliber clinical research; and resources must be used to enhance local technical skills and expand existing personnel. Third, ethics committees must review protocols, monitor the research process, and work closely with research scientists to insure the ethical integrity of research throughout the trials. Fourth, community advisory boards (CAB) need to be formed, linked with existing community leadership structures and organized in conjunction with trial implementation. These community structures should work together with ethics committees to facilitate the study design, informed consent process, and study implementation. We must facilitate communication and mutual understanding between trial communities and research teams, and promote positive collaborations between all stakeholders engaged in EVD research. The community engagement process for EVD research is crucial to address myths and misconceptions, and to promote study volunteers' understanding of the research details. The collaboration between all stakeholders is crucial for continued long term partnership to address EVD outbreak and none of the stakeholders should be left behind in ongoing efforts to develop EVD therapies.

The association of patient foramen ovale (PFO) and migraine headache (migraine) with aura (MA) is well established. Current research suggests a mechanistic link between platelet activation, paradoxical embolization and migraine in some patients. Clopidogrel, a platelet inhibitor, was added to existing migraine therapy, as a 4-week open-label trial in 15 women, aged 16-56 years, with severe migraine and documented right to left shunt (RLS). 13/15 had > 50% reduction or complete elimination of migraine symptoms. After completing the trial period, five responders remain on clopidogrel with ongoing benefit at 11.9 ± 4.5 months (6.5-20), one stopped clopidogrel because of side effects. Nine other responders underwent PFO closure and clopidogrel discontinuation. Eight of nine have had ongoing benefit. Clopidogrel may have a primary prophylactic role in migraine/RLS patients, but may also help select candidates who would benefit from PFO closure. A randomized clinical trial is being established. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Drug-coated balloon (DCB) technologies represent the latest and hottest development in the field of endovascular treatment of peripheral arterial disease. Initial experience with paclitaxel-coated balloon use in the femoral artery has demonstrated lower mid-term restenosis and superior mid-term clinical outcomes in terms of improved wound healing and reduced repeat angioplasty rates compared with standard balloon angioplasty. Many companies are presently developing and/or improving DCB catheters and therefore ongoing, technical improvements of the already existing platforms, new drugs, and innovative carriers are expected. The ongoing basic research studies and various multicenter randomized, controlled trials that are currently in progress will offermore » valuable scientific insights regarding the long-term effectiveness and other crucial issues, such as efficacy in various vascular beds, optimal balloon dosage, and post angioplasty antiplatelet therapy. Future applications of these devices also could include in-stent restenosis, anastomotic stenosis of surgical bypass, and benign stenoses of the central venous system. The authors envision that DCB angioplasty will evolve to a major paradigm shift in the endovascular treatment of occlusive vascular diseases.« less

Attention to change: A multilevel theory on the process of emergent continuous organizational change.

PubMed

Wee, Elijah X M; Taylor, M Susan

Increasingly, continuous organizational change is viewed as the new reality for organizations and their members. However, this model of organizational change, which is usually characterized by ongoing, cumulative, and substantive change from the bottom up, remains underexplored in the literature. Taking a multilevel approach, the authors develop a theoretical model to explain the mechanisms behind the amplification and accumulation of valuable, ongoing work-unit level changes over time, which then become substantial changes at the organizational level. Drawing on the concept of emergence, they first focus on the cognitive search mechanisms of work-unit members and managers to illustrate how work-unit level routine changes may be amplified to the organization through 2 unique processes: composition and compilation emergence. The authors then discuss the managers' role in creating a sense of coherence and meaning for the accumulation of these emergent changes over time. They conclude this research by discussing the theoretical implications of their model for the existing literature of organizational change.

Geoparsing text for characterizing urban operational environments through machine learning techniques

Garfinkle, Noah W.; Selig, Lucas; Perkins, Timothy K.; Calfas, George W.

Increasing worldwide internet connectivity and access to sources of print and open social media has increased near realtime availability of textual information. Capabilities to structure and integrate textual data streams can contribute to more meaningful representations of operational environment factors (i.e., Political, Military, Economic, Social, Infrastructure, Information, Physical Environment, and Time [PMESII-PT]) and tactical civil considerations (i.e., Areas, Structures, Capabilities, Organizations, People and Events [ASCOPE]). However, relying upon human analysts to encode this information as it arrives quickly proves intractable. While human analysts possess an ability to comprehend context in unstructured text far beyond that of computers, automated geoparsing (the extraction of locations from unstructured text) can empower analysts to automate sifting through datasets for areas of interest. This research evaluates existing approaches to geoprocessing as well as initiating the research and development of locally-improved methods of tagging parts of text as possible locations, resolving possible locations into coordinates, and interfacing such results with human analysts. The objective of this ongoing research is to develop a more contextually-complete picture of an area of interest (AOI) including human-geographic context for events. In particular, our research is working to make improvements to geoparsing (i.e., the extraction of spatial context from documents), which requires development, integration, and validation of named-entity recognition (NER) tools, gazetteers, and entity-attribution. This paper provides an overview of NER models and methodologies as applied to geoparsing, explores several challenges encountered, presents preliminary results from the creation of a flexible geoparsing research pipeline, and introduces ongoing and future work with the intention of contributing to the efficient geocoding of information containing valuable insights into human activities in space.

An increasing amount of research activity in computational fluid dynamics has been devoted to the development of efficient algorithms for parallel computing systems. The increasing performance to price ratio of engineering workstations has led to research to development procedures for implementing a parallel computing system composed of distributed workstations. This thesis proposal outlines an ongoing research program to develop efficient strategies for performing three-dimensional flow analysis on distributed computing systems. The PVM parallel programming interface was used to modify an existing three-dimensional flow solver, the TEAM code developed by Lockheed for the Air Force, to function as a parallel flow solver on clusters of workstations. Steady flow solutions were generated for three different wing and body geometries to validate the code and evaluate code performance. The proposed research will extend the parallel code development to determine the most efficient strategies for unsteady flow simulations.

An initial burst of enthusiasm resulted in more than 1000 expressions of interest and nearly 500 internationally coordinated proposals for polar research during IPY. An international committee has endorsed more than 200 of these proposals, and most other proposals and nearly all expressions of interest have found ways to join the endorsed programme. Ten nations have announced new IPY science funding totalling in excess of 300M USD for the two years of operations; several nations will make announcements soon. Most on-going funding for polar research, coming from at least 30 nations, approximately 1.6B USD over two years, will also support IPY activities. What should the thousands of scientists hoping to participate expect, personally and collectively? What should the overall science entity expect, during and after IPY? And, finally, what should the public expect, after much attention and the expenditure of 2B USD, not to mention the on-going and future costs of ice breakers and ice-monitoring satellites and polar bases? Many IPY scientists will initially experience disappointment. Funding, even with IPY infusions, will fall short of need, and initial proposal success rates will stay below 50% in almost every nation, far below in some nations. In many nations, however, a catch-up effect will occur, leading to more funds in 2008 or 2009 than in 2006 and 2007. A step-up effect will also occur, leading to increased on-going funds for polar research, although perhaps in smaller steps and in fewer countries than we might hope. Scientists should expect increased public attention to their work and increased demand for their cooperation and contribution to international data management and to public outreach. Individually and collectively, IPY scientists have the opportunity to interact with an amazing array of fellow scientists, exchanging experience and enthusiasm on topics from gravitational variations to genomic sequences to Gwich'in cultures. Science as an entity will feel the impact of IPY. IPY does not fit within any single science organisation, even one so vast as AGU. A true international IPY community will exist beyond existing organisational systems, and a full multidisciplinary IPY assembly will occur in partnership with but separate from existing events. IPY will stimulate and produce new data models and infrastructure that will allow future polar researchers and polar residents to access, share and explore gravitational, genomic, and Gwich'in information. IPY will also necessarily stir up murky issues between scientific research and the environment, including how mega-science programmes should reduce their own environmental impact and how science conducts its assessments of global environmental problems when its partners include commercial energy companies and when its information products might encourage expanded extractive activities. This IPY will inevitably produce an organisational, data and environmental legacy that will impact science and scientists of the future. The public will expect quick answers from IPY, to questions not necessarily of our choosing. We can expect that they will enjoy a wide array of films and programmes and books on polar themes. We will have failed if the global public does not also gain an improved understanding of polar science and of the global consequences of climate change, and an enhanced appreciation of the creativity, challenges, pleasures and disappointments of science and of the energies and enthusiasms of scientists.

Managers of transdisciplinary collaborative research lack suitable didactic material to support the implementation of research methodologies and to build ongoing partnerships with community representatives and peers, both between and within multiple academic centers. This article will provide insight on the collaborative efforts of project managers involved in multidisciplinary research and their subsequent development of a tool kit for research project managers and/or directors. Project managers from the 8 Centers for Population Health and Health Disparities across the nation participated in monthly teleconferences to share experiences and offer advice on how to achieve high participation rates and maintain community involvement in collaboration with researchers and community leaders to achieve the common goal of decreasing health inequities. In the process, managers recognized and seized the opportunity to produce a tool kit that was designed for future project managers and directors. Project managers in geographically distinct locations maintained a commitment to work together over 4 years and subsequently built upon an existing communications network to design a tool kit that could be disseminated easily to a diverse audience.

2000-01-01

NASA Glenn Research Center has been working with industry, academia, and other government agencies in assessing commercial communications protocols for satellite and space-based applications. In addition, NASA Glenn has been developing and advocating new satellite-friendly modifications to existing communications protocol standards. This paper summarizes recent research into the applicability of various commercial standard protocols for use over satellite and space- based communications networks as well as expectations for future protocol development. It serves as a reference point from which the detailed work can be readily accessed. Areas that will be addressed include asynchronous-transfer-mode quality of service; completed and ongoing work of the Internet Engineering Task Force; data-link-layer protocol development for unidirectional link routing; and protocols for aeronautical applications, including mobile Internet protocol routing for wireless/mobile hosts and the aeronautical telecommunications network protocol.

Multi-tissue DNA methylation age: Molecular relationships and perspectives for advancing biomarker utility.

Nwanaji-Enwerem, Jamaji C; Weisskopf, Marc G; Baccarelli, Andrea A

2018-04-23

The multi-tissue DNA methylation estimator of chronological age (DNAm-age) has been associated with a wide range of exposures and health outcomes. Still, it is unclear how DNAm-age can have such broad relationships and how it can be best utilized as a biomarker. Understanding DNAm-age's molecular relationships is a promising approach to address this critical knowledge gap. In this review, we discuss the existing literature regarding DNAm-age's molecular relationships in six major categories: animal model systems, cancer processes, cellular aging processes, immune system processes, metabolic processes, and nucleic acid processes. We also present perspectives regarding the future of DNAm-age research, including the need to translate a greater number of ongoing research efforts to experimental and animal model systems.

Biomagnetism using SQUIDs: status and perspectives

NASA Astrophysics Data System (ADS)

Sternickel, Karsten; Braginski, Alex I.

2006-03-01

Biomagnetism involves the measurement and analysis of very weak local magnetic fields of living organisms and various organs in humans. Such fields can be of physiological origin or due to magnetic impurities or markers. This paper reviews existing and prospective applications of biomagnetism in clinical research and medical diagnostics. Currently, such applications require sensitive magnetic SQUID sensors and amplifiers. The practicality of biomagnetic methods depends especially on techniques for suppressing the dominant environmental electromagnetic noise, and on suitable nearly real-time data processing and interpretation methods. Of the many biomagnetic methods and applications, only the functional studies of the human brain (magnetoencephalography) and liver susceptometry are in clinical use, while functional diagnostics of the human heart (magnetocardiography) approaches the threshold of clinical acceptance. Particularly promising for the future is the ongoing research into low-field magnetic resonance anatomical imaging using SQUIDs.

Teaching the Mantle Plumes Debate

NASA Astrophysics Data System (ADS)

Foulger, G. R.

2010-12-01

There is an ongoing debate regarding whether or not mantle plumes exist. This debate has highlighted a number of issues regarding how Earth science is currently practised, and how this feeds into approaches toward teaching students. The plume model is an hypothesis, not a proven fact. And yet many researchers assume a priori that plumes exist. This assumption feeds into teaching. That the plume model is unproven, and that many practising researchers are skeptical, may be at best only mentioned in passing to students, with most teachers assuming that plumes are proven to exist. There is typically little emphasis, in particular in undergraduate teaching, that the origin of melting anomalies is currently uncertain and that scientists do not know all the answers. Little encouragement is given to students to become involved in the debate and to consider the pros and cons for themselves. Typically teachers take the approach that “an answer” (or even “the answer”) must be taught to students. Such a pedagogic approach misses an excellent opportunity to allow students to participate in an important ongoing debate in Earth sciences. It also misses the opportunity to illustrate to students several critical aspects regarding correct application of the scientific method. The scientific method involves attempting to disprove hypotheses, not to prove them. A priori assumptions should be kept uppermost in mind and reconsidered at all stages. Multiple working hypotheses should be entertained. The predictions of a hypothesis should be tested, and unpredicted observations taken as weakening the original hypothesis. Hypotheses should not be endlessly adapted to fit unexpected observations. The difficulty with pedagogic treatment of the mantle plumes debate highlights a general uncertainty about how to teach issues in Earth science that are not yet resolved with certainty. It also represents a missed opportunity to let students experience how scientific theories evolve, warts and all. Working with students to enable them to participate in the evolution of the subject and to share in the excitement of major developments is surely the best way to attract them to science.

Economic performance of water storage capacity expansion for food security

Gohar, Abdelaziz A.; Ward, Frank A.; Amer, Saud A.

2013-03-01

SummaryContinued climate variability, population growth, and rising food prices present ongoing challenges for achieving food and water security in poor countries that lack adequate water infrastructure. Undeveloped storage infrastructure presents a special challenge in northern Afghanistan, where food security is undermined by highly variable water supplies, inefficient water allocation rules, and a damaged irrigation system due three decades of war and conflict. Little peer-reviewed research to date has analyzed the economic benefits of water storage capacity expansions as a mechanism to sustain food security over long periods of variable climate and growing food demands needed to feed growing populations. This paper develops and applies an integrated water resources management framework that analyzes impacts of storage capacity expansions for sustaining farm income and food security in the face of highly fluctuating water supplies. Findings illustrate that in Afghanistan's Balkh Basin, total farm income and food security from crop irrigation increase, but at a declining rate as water storage capacity increases from zero to an amount equal to six times the basin's long term water supply. Total farm income increases by 21%, 41%, and 42% for small, medium, and large reservoir capacity, respectively, compared to the existing irrigation system unassisted by reservoir storage capacity. Results provide a framework to target water infrastructure investments that improve food security for river basins in the world's dry regions with low existing storage capacity that face ongoing climate variability and increased demands for food security for growing populations.

PARTICLE_RISK was one of the first multidisciplinary projects funded by the European Commission's Framework Programme that was responsible for evaluating the implications of nanomaterial (NM) exposure on human health. This project was the basis for this review which identifies the challenges that exist within the assessment of NM risk. We have retrospectively reflected on the findings of completed nanotoxicology studies to consider what progress and advances have been made within the risk assessment of NMs, as well as discussing the direction that nanotoxicology research is taking and identifying the limitations and failings of existing research. We have reflected on what commonly encountered challenges exist and explored how these issues may be resolved. In particular, the following is discussed (i) NM selection (ii) NM physico-chemical characterisation; (iii) NM dispersion; (iv) selection of relevant doses and concentrations; (v) identification of relevant models, target sites and endpoints; (vi) development of alternatives to animal testing; and (vii) NM risk assessment. These knowledge gaps are relatively well recognised by the scientific community and recommendations as to how they may be overcome in the future are provided. It is hoped that this will help develop better defined hypothesis driven research in the future that will enable comprehensive risk assessments to be conducted for NMs. Importantly, the nanotoxicology community has responded and adapted to advances in knowledge over recent years to improve the approaches used to assess NM hazard, exposure and risk. It is vital to learn from existing information provided by ongoing or completed studies to avoid unnecessary duplication of effort, and to offer guidance on aspects of the experimental design that should be carefully considered prior to the start of a new study.

Ongoing training of community health workers in low-income and middle-income countries: a systematic scoping review of the literature

O’Donovan, Charles; Kuhn, Isla; Sachs, Sonia Ehrlich

2018-01-01

Objectives Understanding the current landscape of ongoing training for community health workers (CHWs) in low-income and middle-income countries (LMICs) is important both for organisations responsible for their training, as well as researchers and policy makers. This scoping review explores this under-researched area by mapping the current delivery implementation and evaluation of ongoing training provision for CHWs in LMICs. Design Systematic scoping review. Data sources MEDLINE, Embase, AMED, Global Health, Web of Science, Scopus, ASSIA, LILACS, BEI and ERIC. Study selection Original studies focusing on the provision of ongoing training for CHWs working in a country defined as low income and middle income according to World Bank Group 2012 classification of economies. Results The scoping review found 35 original studies that met the inclusion criteria. Ongoing training activities for CHWs were described as supervision (n=19), inservice or refresher training (n=13) or a mixture of both (n=3). Although the majority of studies emphasised the importance of providing ongoing training, several studies reported no impact of ongoing training on performance indicators. The majority of ongoing training was delivered inperson; however, four studies reported the use of mobile technologies to support training delivery. The outcomes from ongoing training activities were measured and reported in different ways, including changes in behaviour, attitudes and practice measured in a quantitative manner (n=16), knowledge and skills (n=6), qualitative assessments (n=5) or a mixed methods approach combining one of the aforementioned modalities (n=8). Conclusions This scoping review highlights the diverse range of ongoing training for CHWs in LMICs. Given the expansion of CHW programmes globally, more attention should be given to the design, delivery, monitoring and sustainability of ongoing training from a health systems strengthening perspective.

Cultivating cohort studies for observational translational research.

PubMed

Ransohoff, David F

2013-04-01

"Discovery" research about molecular markers for diagnosis, prognosis, or prediction of response to therapy has frequently produced results that were not reproducible in subsequent studies. What are the reasons, and can observational cohorts be cultivated to provide strong and reliable answers to those questions? Experimental Selected examples are used to illustrate: (i) what features of research design provide strength and reliability in observational studies about markers of diagnosis, prognosis, and response to therapy? (ii) How can those design features be cultivated in existing observational cohorts, for example, within randomized controlled clinical trial (RCT), other existing observational research studies, or practice settings like health maintenance organization (HMOs)? Examples include a study of RNA expression profiles of tumor tissue to predict prognosis of breast cancer, a study of serum proteomics profiles to diagnose ovarian cancer, and a study of stool-based DNA assays to screen for colon cancer. Strengths and weaknesses of observational study design features are discussed, along with lessons about how features that help assure strength might be "cultivated" in the future. By considering these examples and others, it may be possible to develop a process of "cultivating cohorts" in ongoing RCTs, observational cohort studies, and practice settings like HMOs that have strong features of study design. Such an effort could produce sources of data and specimens to reliably answer questions about the use of molecular markers in diagnosis, prognosis, and response to therapy.

Concern that "EMF" magnetic fields from power lines cause cancer.

PubMed

Repacholi, Michael

2012-06-01

In 2002, the International Agency for Research on Cancer (IARC, 2002) categorized extremely low frequency (ELF) (including the power frequencies of 50 and 60 Hz) magnetic fields as "possibly carcinogenic to humans." That was based on pooled analyses of epidemiological research that reported an association between exposure to low-level magnetic fields and childhood leukemia. In 2007 a task group of scientific experts convened by the World Health Organization (WHO) acknowledged the IARC categorization but found that the laboratory studies and other research results did not support the association. Taking all evidence into account WHO reported that it could not confirm the existence of any health consequences from exposure to low-level magnetic fields. There remains continuing concern by some people that exposure to power frequency magnetic fields may cause adverse health effects, particularly childhood leukemia. Public health authorities need to fully understand the reasons for that ongoing concern and effective ways to address it. This paper describes what drives the concern, including how people perceive risks, how WHO and other public health authorities assess scientific research to determine whether health risks exist and the conclusions they have reached about power frequency magnetic fields. This paper also addresses the scientific basis of international exposure guidelines for power frequency magnetic fields and what precautionary measures are warranted to address the concern.

Provide credible estimates of the start-up and ongoing effort and incremental practice expenses for the Advancing Care Together (ACT) behavioral health and primary care integration interventions. Expenditure data were collected from 10 practice intervention sites using an instrument with a standardized general format that could accommodate the unique elements of each intervention. Average start-up effort expenses were $44,076 and monthly ongoing effort expenses per patient were $40.39. Incremental expenses averaged $20,788 for start-up and $4.58 per patient for monthly ongoing activities. Variations in expenditures across practices reflect the differences in intervention specifics and organizational settings. Differences in effort to incremental expenditures reflect the extensive use of existing resources in implementing the interventions. ACT program incremental expenses suggest that widespread adoption would likely have a relatively modest effect on overall health systems expenditures. Practice effort expenses are not trivial and may pose barriers to adoption. Payers and purchasers interested in attaining widespread adoption of integrated care must consider external support to practices that accounts for both incremental and effort expense levels. Existing knowledge transfer mechanisms should be employed to minimize developmental start-up expenses and payment reform focused toward value-based, Triple Aim-oriented reimbursement and purchasing mechanisms are likely needed. © Copyright 2015 by the American Board of Family Medicine.

This paper describes ongoing research into modeling and simulation of humans for launch team analysis, training, and evaluation. The initial research is sponsored by the National Aeronautics and Space Administration's (NASA)'s Office of Safety and Mission Assurance (OSMA) and NASA's Exploration Program and is focused on current and future launch team operations at Kennedy Space Center (KSC). The paper begins with a description of existing KSC launch team environments and procedures. It then describes the goals of new Simulation and Analysis of Launch Teams (SALT) research. The majority of this paper describes products from the SALT team's initial proof-of-concept effort. These products include a nominal case task analysis and a discrete event model and simulation of launch team performance during the final phase of a shuttle countdown; and a first proof-of-concept training demonstration of launch team communications in which the computer plays most roles, and the trainee plays a role of the trainee's choice. This paper then describes possible next steps for the research team and provides conclusions. This research is expected to have significant value to NASA's Exploration Program.

It’s plain and simple: transparency is good for science and in the public interest

PubMed Central

2013-01-01

In the past couple of years, there has been a growing focus on the need to make scientific output accessible to a greater number of people, especially in the field of clinical research. The public are being urged to become more well-informed and to ask their doctors about taking part in clinical trials. A key finding of a report from the Association of Medical Research Charities was that all published scientific papers would benefit from having a section in plain English. Researchers running a clinical trial are expected to provide a summary of their intended research at various stages of the research process. However, there is evidence that existing summaries are of variable length and quality and not always in plain English. As a result, the National Institute for Health Research (NIHR) commissioned a review of the guidance that is available to researchers. However, recent initiatives demonstrate that there are still a number of challenges in making current research both accessible and understandable by prospective participants. BioMed Central also has a number of ongoing initiatives involving trial registration services and journals. PMID:23849479

Compared to chemotherapy, promising results have been obtained by blocking the PD-1 pathway using antibodies that inhibit programmed cell death protein 1 (PD-1) or programmed cell death protein ligand 1 (PD-L1). Furthermore, global researchers and doctors are exploring how to optimize this immunotherapy in 270 clinical studies. However, Chinese clinical trials of these agents remain in the early stages. We summarize the ongoing international and domestic clinical trials using PD-1 and PD-L1 inhibitors to treat lung cancer. This information can help researchers better understand the active and approved clinical trials in China, as well as the ongoing research regarding PD-1 and PD-L1 inhibitors.

2018-01-01

Transfusions of red blood cells (RBCs), platelets, and plasma are critical therapies for infants and neonates (particularly preterm neonates) in the neonatal intensive care unit, who are the most frequently transfused subpopulation across all ages. Although traditionally a significant gap has existed between the blood utilization and the evidence base essential to adequately guide transfusion practices in infants and neonates, pediatric transfusion medicine is evolving from infancy and gradually coming of age. It is entering an exciting era with recognition as an independent discipline, a new and evolving high-quality evidence base for transfusion practices, novel technologies and therapeutics, and national/international collaborative research, educational, and clinical efforts. Triggers and thresholds for red cell transfusion are accumulating evidence with current phase III clinical trials. Ongoing trials and studies of platelet and plasma transfusions in neonates are anticipated to provide high-quality evidence in years to come. This article aims to summarize the most current evidence-based practices regarding blood component therapy in neonates. Data on the use of specific components (RBCs, plasma, and platelets) are provided. We attempt to define thresholds for anemia, thrombocytopenia, and abnormal coagulation profile in neonates to highlight the difficulties in having a specific cutoff value in neonates and preterm infants. Indications for transfusion of specific products, transfusion thresholds, and current practices and guidelines are provided, and possible adverse outcomes and complications are discussed. Finally, the critical research knowledge gaps in these practices as well as ongoing and future research areas are discussed. In an era of personalized medicine, neonatal transfusion decisions guided by a strong evidence base must be the overarching goal, and this underlies all of the strategic initiatives in pediatric and neonatal transfusion research highlighted in this article.

Sarcopenia research may be hampered by the heterogeneity of populations and outcome measures used in clinical studies. The aim of this study was to describe the inclusion/exclusion criteria and outcome measures used in ongoing research in sarcopenia. All active intervention studies registered in the World Health Organization with the keyword sarcopenia were included. Study design, type of intervention, inclusion/exclusion criteria and outcome measures were registered and classified. In April 2014, 151 studies on sarcopenia were registered in the WHO database. One hundred twenty-three were intervention studies. Most trials (94.3 %) were single centre and randomized (93.5 %), 51.2 % were double blind. Nutritional interventions (36.6 %), physical exercise (12.2 %) or both (19.5 %) were the most common interventions tested. Only 54.4 % included subjects of both genders, and 46.3 % had an upper age limit. Definition of the target populations was heterogeneous, with 57.7 % including healthy subjects and none using recent definitions of sarcopenia. Lifestyle and the degree of physical activity of subjects were not described or considered in most cases (79.7 %). Subjects with cardiovascular, neuropsychiatric or metabolic disorders and those with physical disability were usually excluded. Muscle mass and muscle strength were the primary outcome variables in 28.5 and 29.5 % of studies and physical performance in 19.5 %, but only 4.1 % used the three variables used the three of them. An additional 26.8 % used biological outcome variables. Little information and agreement existed in the way muscle and physical performance parameters were measured. We found a large heterogeneity in trial design, definition of populations and outcome measures in present research.

Risk analysis for U.S. offshore wind farms: the need for an integrated approach.

PubMed

Staid, Andrea; Guikema, Seth D

2015-04-01

Wind power is becoming an increasingly important part of the global energy portfolio, and there is growing interest in developing offshore wind farms in the United States to better utilize this resource. Wind farms have certain environmental benefits, notably near-zero emissions of greenhouse gases, particulates, and other contaminants of concern. However, there are significant challenges ahead in achieving large-scale integration of wind power in the United States, particularly offshore wind. Environmental impacts from wind farms are a concern, and these are subject to a number of on-going studies focused on risks to the environment. However, once a wind farm is built, the farm itself will face a number of risks from a variety of hazards, and managing these risks is critical to the ultimate achievement of long-term reductions in pollutant emissions from clean energy sources such as wind. No integrated framework currently exists for assessing risks to offshore wind farms in the United States, which poses a challenge for wind farm risk management. In this "Perspective", we provide an overview of the risks faced by an offshore wind farm, argue that an integrated framework is needed, and give a preliminary starting point for such a framework to illustrate what it might look like. This is not a final framework; substantial work remains. Our intention here is to highlight the research need in this area in the hope of spurring additional research about the risks to wind farms to complement the substantial amount of on-going research on the risks from wind farms. © 2015 Society for Risk Analysis.

Research Ethics Education in the STEM Disciplines: The Promises and Challenges of a Gaming Approach.

2016-02-01

While education in ethics and the responsible conduct of research (RCR) is widely acknowledged as an essential component of graduate education, particularly in the STEM disciplines (science, technology, engineering, and math), little consensus exists on how best to accomplish this goal. Recent years have witnessed a turn toward the use of games in this context. Drawing from two NSF-funded grants (one completed and one on-going), this paper takes a critical look at the use of games in ethics and RCR education. It does so by: (a) setting the development of research and engineering ethics games in wider historical and theoretical contexts, which highlights their promise to solve important pedagogical problems; (b) reporting on some initial results from our own efforts to develop a game; and (c) reflecting on the challenges that arise in using games for ethics education. In our discussion of the challenges, we draw out lessons to improve this nascent approach to ethics education in the STEM disciplines .

A conceptual prototype for the next-generation national elevation dataset

2013-01-01

In 2012 the U.S. Geological Survey's (USGS) National Geospatial Program (NGP) funded a study to develop a conceptual prototype for a new National Elevation Dataset (NED) design with expanded capabilities to generate and deliver a suite of bare earth and above ground feature information over the United States. This report details the research on identifying operational requirements based on prior research, evaluation of what is needed for the USGS to meet these requirements, and development of a possible conceptual framework that could potentially deliver the kinds of information that are needed to support NGP's partners and constituents. This report provides an initial proof-of-concept demonstration using an existing dataset, and recommendations for the future, to inform NGP's ongoing and future elevation program planning and management decisions. The demonstration shows that this type of functional process can robustly create derivatives from lidar point cloud data; however, more research needs to be done to see how well it extends to multiple datasets.

2014-02-18

Malaria is one of the most important tropical diseases that has caused devastation throughout the history of mankind. Malaria eradication programmes in the past have had many positive effects but failed to wipe out malaria from most tropical countries, including Sri Lanka. Encouraged by the impressive levels of reduction in malaria case numbers during the past decade, Sri Lanka has launched a programme to eliminate malaria by year 2014. This article reviews the historical milestones associated with the malaria eradication programme that failed subsequently and the events that led to the launch of the ongoing malaria elimination plans at national-level and its strategies that are operational across the entire country. The existing gaps in knowledge are also discussed together with the priority areas for research to fill in these gaps that are posing as challenges to the envisaged goal of wiping out malaria from this island nation.

Is parental socio-economic status related to the initiation of substance abuse by young people in an English city? An event history analysis.

PubMed

Sutherland, Alex

2012-04-01

This paper aims to examine the relationship between parental socio-economic status (SES) and adolescent substance use. The central question posed in the title is approached in two stages. First, theoretical and empirical research in this area is reviewed. Second, data from an ongoing longitudinal study of young people in England (the Peterborough Adolescent and Young Adult Development Study--PADS+) are used to highlight the nature of this relationship in one city. Results from discrete-time event history analyses show that when examining what predicts initiation of substance use, familial and demographic factors emerge as important predictors, but SES does not appear to be relevant.

Moore, Michael S.; Price, Jeremy C.; Reinhart, Richard; Liebetreu, John; Kacpura, Tom J.

2005-01-01

This paper presents the tool chain, methodology, and results of an on-going study being performed jointly by Space Communication Experts at NASA Glenn Research Center (GRC), General Dynamics C4 Systems (GD), and Southwest Research Institute (SwRI). The team is evaluating the applicability and tradeoffs concerning the use of Software Defined Radio (SDR) technologies for Space missions. The Space Telecommunications Radio Systems (STRS) project is developing an approach toward building SDR-based transceivers for space communications applications based on an accompanying software architecture that can be used to implement transceivers for NASA space missions. The study is assessing the overall cost and benefit of employing SDR technologies in general, and of developing a software architecture standard for its space SDR transceivers. The study is considering the cost and benefit of existing architectures, such as the Joint Tactical Radio Systems (JTRS) Software Communications Architecture (SCA), as well as potential new space-specific architectures.

The experience of weight management in normal weight adults.

No prior research has been done with normal weight persons specific to their experience of weight management. The purpose of this research was to discover the experience of weight management in normal weight individuals. Glaserian grounded theory was used. Qualitative data (focus group) and quantitative data (food diary, study questionnaire, and anthropometric measures) were collected. Weight management was an ongoing process of trying to focus on living (family, work, and social), while maintaining their normal weight targets through five consciously and unconsciously used strategies. Despite maintaining normal weights, the nutritional composition of foods eaten was grossly inadequate. These five strategies can be used to develop new weight management strategies that could be integrated into existing weight management programs, or could be developed into novel weight management interventions. Surprisingly, normal weight individuals require dietary assessment and nutrition education to prevent future negative health consequences. Copyright © 2016 Elsevier Inc. All rights reserved.

Conventional and Non-Conventional Drosophila Toll Signaling

PubMed Central

Lindsay, Scott A.; Wasserman, Steven A.

2013-01-01

The discovery of Toll in Drosophila and of the remarkable conservation in pathway composition and organization catalyzed a transformation in our understanding of innate immune recognition and response. At the center of that picture is a cascade of interactions in which specific microbial cues activate Toll receptors, which then transmit signals driving transcription factor nuclear localization and activity. Experiments gave substance to the vision of pattern recognition receptors, linked phenomena in development, gene regulation, and immunity into a coherent whole, and revealed a rich set of variations for identifying non-self and responding effectively. More recently, research in Drosophila has illuminated the positive and negative regulation of Toll activation, the organization of signaling events at and beneath membranes, the sorting of information flow, and the existence of non-conventional signaling via Toll-related receptors. Here, we provide an overview of the Toll pathway of flies and highlight these ongoing realms of research. PMID:23632253

The Lancet Countdown: tracking progress on health and climate change is an international, multidisciplinary research collaboration between academic institutions and practitioners across the world. It follows on from the work of the 2015 Lancet Commission, which concluded that the response to climate change could be "the greatest global health opportunity of the 21st century". The Lancet Countdown aims to track the health impacts of climate hazards; health resilience and adaptation; health co-benefits of climate change mitigation; economics and finance; and political and broader engagement. These focus areas form the five thematic working groups of the Lancet Countdown and represent different aspects of the complex association between health and climate change. These thematic groups will provide indicators for a global overview of health and climate change; national case studies highlighting countries leading the way or going against the trend; and engagement with a range of stakeholders. The Lancet Countdown ultimately aims to report annually on a series of indicators across these five working groups. This paper outlines the potential indicators and indicator domains to be tracked by the collaboration, with suggestions on the methodologies and datasets available to achieve this end. The proposed indicator domains require further refinement, and mark the beginning of an ongoing consultation process-from November, 2016 to early 2017-to develop these domains, identify key areas not currently covered, and change indicators where necessary. This collaboration will actively seek to engage with existing monitoring processes, such as the UN Sustainable Development Goals and WHO's climate and health country profiles. The indicators will also evolve over time through ongoing collaboration with experts and a range of stakeholders, and be dependent on the emergence of new evidence and knowledge. During the course of its work, the Lancet Countdown will adopt a collaborative and iterative process, which aims to complement existing initiatives, welcome engagement with new partners, and be open to developing new research projects on health and climate change.

Criteria used by nurses to evaluate practice-related information on the World Wide Web.

PubMed

Cader, Raffik; Campbell, Steve; Watson, Don

2003-01-01

Existing criteria used to evaluate information on the World Wide Web often are not related to nursing, especially in relation to clinical and evidence-based practice. Published criteria have been found orientated to the health-consumer, medicine, or general information. In this study, the process by which nurses evaluate practice-related information and the associated evaluative nursing criteria were investigated using a grounded theory approach. In the first stage of this ongoing investigation, semistructured interviews were used to collect data from UK postregistration nursing students. The findings from this initial study provided indications of the process and the criteria for evaluating information on the World Wide Web. Participating students identified intuition as part of the evaluative process. They identified some criteria similar to existing standards, but critically, with additional criteria that are nursing practice related. Because these new criteria are significant for evaluating nursing information, further refinement of these findings is being undertaken through the next stage of the research program.

Genes and plays: bringing ELSI issues to life.

PubMed

Rothenberg, Karen H; Bush, Lynn W

2012-02-01

Ethical complexities surround the promise of genomic technology and the power of genetic information as they alter conceptions of identity and dynamics within personal and professional relationships. Creative approaches such as dramatic vignettes offer a unique analytical stage for imagining the bioethical past and future. Dramatic narratives can bring to life images of differing perspectives and values when experiencing innovations in medicine. Although the scientific landscape shifts, concerns expressed in theatre from 50 years ago parallel many contemporary ELSI (ethical, legal, and social implications) issues, highlighting the ongoing struggle to appreciate the impact of emerging genetic technologies on relationships. To illuminate these enduring concerns, we explore how perceptions and relationships have influenced-and been influenced by-genetics as portrayed through dramatic vignettes. We build on the legacy of using case vignettes as a clinical teaching modality, and believe similar value exists within the research ethics domain. The selection of dialogue discussed encompasses abbreviated excerpts from two existing and one original vignette that we staged at the ELSI 2011 Congress and various academic and health institutions.

Burke, James; Turner, Barbara; Vroom, James; Short, Nancy

2015-01-01

Abstract Researcher‐initiated biobanks based at academic institutions contribute valuable biomarker and translational research advances to medicine. With many legacy banks once supported by federal funding, reductions in fiscal support threaten the future of existing and new biobanks. When the Brain Bank at Duke University's Bryan Alzheimer's Disease Center (ADRC) faced a funding crisis, a collaborative, multidisciplinary team embarked on a 2‐year biobank sustainability project utilizing a comprehensive business strategy, dedicated project management, and a systems approach involving many Duke University entities. By synthesizing and applying existing knowledge, Duke Translational Medicine Institute created and launched a business model that can be adjusted and applied to legacy and start‐up academic biobanks. This model provides a path to identify new funding mechanisms, while also emphasizing improved communication, business development, and a focus on collaborating with industry to improve access to biospecimens. Benchmarks for short‐term Brain Bank stabilization have been successfully attained, and the evaluation of long‐term sustainability metrics is ongoing. PMID:25996355

Cochrane systematic reviews are useful to map research gaps for decreasing maternal mortality.

To use an "evidence-mapping" approach to assess the usefulness of Cochrane reviews in identifying research gaps in the maternal health. The article describes the general mapping, prioritizing, reconciling, and updating approach: (1) identifying gaps in the maternal health research using published systematic reviews and formulating research questions, (2) prioritizing questions using Delphi method, (3) reconciling identified research priorities with the existing literature (i.e., searching of ongoing trials in trials registries), (4) updating the process. A comprehensive search of Cochrane systematic reviews published or updated from January 2006 to March 2011 was performed. We evaluated the "Implications for Research" section to identify gaps in the research. Our search strategy identified 695 references; 178 systematic reviews identifying at least one research gap were used. We formulated 319 research questions, which were classified into 11 different categories based on the direct and indirect causes of maternal mortality: postpartum hemorrhage, abortion, hypertensive disorders, infection/sepsis, caesarean section, diabetes, pregnancy prevention, preterm labor, other direct causes, indirect causes, and health policies and systems. Most research questions concerned the effectiveness of clinical interventions, including drugs (42.6%), nonpharmacologic interventions (16.3%), and health system (14.7%). It is possible to identify gaps in the maternal health research by using this approach. Copyright © 2013 Elsevier Inc. All rights reserved.

2018-04-28

Understanding the current landscape of ongoing training for community health workers (CHWs) in low-income and middle-income countries (LMICs) is important both for organisations responsible for their training, as well as researchers and policy makers. This scoping review explores this under-researched area by mapping the current delivery implementation and evaluation of ongoing training provision for CHWs in LMICs. Systematic scoping review. MEDLINE, Embase, AMED, Global Health, Web of Science, Scopus, ASSIA, LILACS, BEI and ERIC. Original studies focusing on the provision of ongoing training for CHWs working in a country defined as low income and middle income according to World Bank Group 2012 classification of economies. The scoping review found 35 original studies that met the inclusion criteria. Ongoing training activities for CHWs were described as supervision (n=19), inservice or refresher training (n=13) or a mixture of both (n=3). Although the majority of studies emphasised the importance of providing ongoing training, several studies reported no impact of ongoing training on performance indicators. The majority of ongoing training was delivered inperson; however, four studies reported the use of mobile technologies to support training delivery. The outcomes from ongoing training activities were measured and reported in different ways, including changes in behaviour, attitudes and practice measured in a quantitative manner (n=16), knowledge and skills (n=6), qualitative assessments (n=5) or a mixed methods approach combining one of the aforementioned modalities (n=8). This scoping review highlights the diverse range of ongoing training for CHWs in LMICs. Given the expansion of CHW programmes globally, more attention should be given to the design, delivery, monitoring and sustainability of ongoing training from a health systems strengthening perspective. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Developing and Sustaining Recovery-Orientation in Mental Health Practice: Experiences of Occupational Therapists.

PubMed

Nugent, Alexandra; Hancock, Nicola; Honey, Anne

2017-01-01

Internationally, mental health policy requires clinicians to shift from a medical to a recovery-oriented approach. However, there is a significant lag in the translation of policy into practice. Occupational therapists have been identified as ideally situated to be recovery-oriented yet limited research exploring how they do this exists. This study aimed to explore Australian occupational therapists' experiences of developing and sustaining recovery-orientation in mental health practice. Semistructured, in-depth interviews were conducted with twelve occupational therapists working across different mental health service types. Participants identified themselves as being recovery-oriented. Data were analysed using constant comparative analysis. Occupational therapists described recovery-oriented practice as an active, ongoing, and intentional process of seeking out knowledge, finding fit between understandings of recovery-oriented practice and their professional identity, holding hope, and developing confidence through clinical reasoning. Human and systemic aspects of therapists' workplace environment influenced this process. Being a recovery-oriented occupational therapist requires more than merely accepting a specific framework. It requires commitment and ongoing work to develop and sustain recovery-orientation. Occupational therapists are called to extend current leadership activity beyond their workplace and to advocate for broader systemic change.

Mathematical biology modules based on modern molecular biology and modern discrete mathematics.

2010-01-01

We describe an ongoing collaborative curriculum materials development project between Sweet Briar College and Western Michigan University, with support from the National Science Foundation. We present a collection of modules under development that can be used in existing mathematics and biology courses, and we address a critical national need to introduce students to mathematical methods beyond the interface of biology with calculus. Based on ongoing research, and designed to use the project-based-learning approach, the modules highlight applications of modern discrete mathematics and algebraic statistics to pressing problems in molecular biology. For the majority of projects, calculus is not a required prerequisite and, due to the modest amount of mathematical background needed for some of the modules, the materials can be used for an early introduction to mathematical modeling. At the same time, most modules are connected with topics in linear and abstract algebra, algebraic geometry, and probability, and they can be used as meaningful applied introductions into the relevant advanced-level mathematics courses. Open-source software is used to facilitate the relevant computations. As a detailed example, we outline a module that focuses on Boolean models of the lac operon network.

Biosensor UUV payload for underwater detection

Kusterbeck, Anne W.; Charles, Paul T.; Melde, Brian J.; Trammell, Scott A.; Adams, André A.; Deschamps, Jeffrey R.

2010-04-01

Increased emphasis on maritime domain awareness and port security has led to the development of unmanned underwater vehicles (UUVs) capable of extended missions. These systems rely most frequently on well-developed side scan sonar and acoustic methods to locate potential targets. The Naval Research Laboratory (NRL) is developing biosensors for underwater explosives detection that complement acoustic sensors and can be used as UUV payloads to monitor areas for port and harbor security or in detection of underwater unexploded ordnance (UXO) and biochemical threats. The prototype sensor has recently been demonstrated to detect explosives in seawater at trace levels when run in a continuous sampling mode. To overcome ongoing issues with sample preparation and facilitate rapid detection at trace levels in a marine environment, we have been developing new mesoporous materials for in-line preconcentration of explosives and other small molecules, engineering microfluidic components to improve the signal, and testing alternative signal transduction methods. Additional work is being done to optimize the optical components and sensor response time. Highlights of these current studies and our ongoing efforts to integrate the biosensor with existing detection technologies to reduce false positives are described. In addition, we present the results of field tests that demonstrate the prototype biosensor performance as a UUV payload.

The fate of completed intentions.

PubMed

Anderson, Francis T; Einstein, Gilles O

2017-04-01

The goal of this research was to determine whether and how people deactivate prospective memory (PM) intentions after they have been completed. One view proposes that PM intentions can be deactivated after completion, such that they no longer come to mind and interfere with current tasks. Another view is that now irrelevant completed PM intentions exhibit persisting activation, and continue to be retrieved. In Experiment 1, participants were given a PM intention embedded within the ongoing task during Phase 1, after which participants were told either that the PM task had been completed or suspended until later. During Phase 2, participants were instructed to perform only the ongoing task and were periodically prompted to report their thoughts. Critically, the PM targets from Phase 1 reappeared in Phase 2. All of our measures, including thoughts reported about the PM task, supported the existence of persisting activation. In Experiment 2, we varied conditions that were expected to mitigate persisting activation. Despite our best attempts to promote deactivation, we found evidence for the persistence of spontaneous retrieval in all groups after intentions were completed. The theoretical and practical implications of this potential dark side to spontaneous retrieval are discussed.

Aim To review key studies evaluating stereotactic radiotherapy in the setting of early-stage non-small cell lung cancer (NSCLC) for inoperable or high-risk patients, and discuss areas of ongoing research and clinical trials. Background The use of stereotactic radiotherapy for the treatment of early stage non-small cell lung cancer (NSCLC) has increased rapidly over the past decade. Numerous studies have reported outcomes for patients treated with SBRT who are unfit for surgical resection, or at high risk of surgical complications. Materials and methods A narrative review. Results The preponderance of evidence suggests that SBRT is associated with excellent local control (∼90% at 3 years) and a favorable toxicity profile. In patients with higher operative risks, such as the elderly and patients with severe COPD, SBRT may provide a less-toxic treatment than surgery with similar oncologic outcomes. Ongoing studies are evaluating the use of SBRT for locally advanced or oligometastatic NSCLC. Conclusions A large body of evidence now exists to support the use of SBRT for early-stage NSCLC. Decisions regarding the optimal choice of treatment should be individualized, and made in the context of a multidisciplinary team. PMID:26696779

One mission of the Crosscutting Technology Research program at the National Energy Technology Laboratory is to develop a suite of sensors and controls technologies that will ultimately increase efficiencies of existing fossil-fuel fired power plants and enable a new generation of more efficient and lower emission power generation technologies. The program seeks to accomplish this mission through soliciting, managing, and monitoring a broad range of projects both internal and external to the laboratory which span sensor material and device development, energy harvesting and wireless telemetry methodologies, and advanced controls algorithms and approaches. A particular emphasis is placed upon harsh environment sensing for compatibility with high temperature, erosive, corrosive, and highly reducing or oxidizing environments associated with large-scale centralized power generation. An overview of the full sensors and controls portfolio is presented and a selected set of current and recent research successes and on-going projects are highlighted. A more detailed emphasis will be placed on an overview of the current research thrusts and successes of the in-house sensor material and device research efforts that have been established to support the program.

Focusing the research agenda for simulation training visual system requirements

NASA Astrophysics Data System (ADS)

Lloyd, Charles J.

2014-06-01

Advances in the capabilities of the display-related technologies with potential uses in simulation training devices continue to occur at a rapid pace. Simultaneously, ongoing reductions in defense spending stimulate the services to push a higher proportion of training into ground-based simulators to reduce their operational costs. These two trends result in increased customer expectations and desires for more capable training devices, while the money available for these devices is decreasing. Thus, there exists an increasing need to improve the efficiency of the acquisition process and to increase the probability that users get the training devices they need at the lowest practical cost. In support of this need the IDEAS program was initiated in 2010 with the goal of improving display system requirements associated with unmet user needs and expectations and disrupted acquisitions. This paper describes a process of identifying, rating, and selecting the design parameters that should receive research attention. Analyses of existing requirements documents reveal that between 40 and 50 specific design parameters (i.e., resolution, contrast, luminance, field of view, frame rate, etc.) are typically called out for the acquisition of a simulation training display system. Obviously no research effort can address the effects of this many parameters. Thus, we developed a defensible strategy for focusing limited R&D resources on a fraction of these parameters. This strategy encompasses six criteria to identify the parameters most worthy of research attention. Examples based on display design parameters recommended by stakeholders are provided.

Realistic computer network simulation for network intrusion detection dataset generation

NASA Astrophysics Data System (ADS)

Payer, Garrett

2015-05-01

The KDD-99 Cup dataset is dead. While it can continue to be used as a toy example, the age of this dataset makes it all but useless for intrusion detection research and data mining. Many of the attacks used within the dataset are obsolete and do not reflect the features important for intrusion detection in today's networks. Creating a new dataset encompassing a large cross section of the attacks found on the Internet today could be useful, but would eventually fall to the same problem as the KDD-99 Cup; its usefulness would diminish after a period of time. To continue research into intrusion detection, the generation of new datasets needs to be as dynamic and as quick as the attacker. Simply examining existing network traffic and using domain experts such as intrusion analysts to label traffic is inefficient, expensive, and not scalable. The only viable methodology is simulation using technologies including virtualization, attack-toolsets such as Metasploit and Armitage, and sophisticated emulation of threat and user behavior. Simulating actual user behavior and network intrusion events dynamically not only allows researchers to vary scenarios quickly, but enables online testing of intrusion detection mechanisms by interacting with data as it is generated. As new threat behaviors are identified, they can be added to the simulation to make quicker determinations as to the effectiveness of existing and ongoing network intrusion technology, methodology and models.

Graphene has recently enabled the dramatic improvement of portable electronics and electric vehicles by providing better means for storing electricity. In this Review, we discuss the current status of graphene in energy storage and highlight ongoing research activities, with specific emphasis placed on the processing of graphene into electrodes, which is an essential step in the production of devices. We calculate the maximum energy density of graphene supercapacitors and outline ways for future improvements. We also discuss the synthesis and assembly of graphene into macrostructures, ranging from 0D quantum dots, 1D wires, 2D sheets and 3D frameworks, to potentially 4D self-folding materials that allow the design of batteries and supercapacitors with many new features that do not exist in current technology.

Usability of Security Management:Defining the Permissions of Guests

NASA Astrophysics Data System (ADS)

Johnson, Matthew; Stajano, Frank

Within the scenario of a Smart Home, we discuss the issues involved in allowing limited interaction with the environment for unidentified principals, or guests. The challenges include identifying and authenticating guests on one hand and delegating authorization to them on the other. While the technical mechanisms for doing so in generic distributed systems have been around for decades, existing solutions are in general not applicable to the smart home because they are too complex to manage. We focus on providing both security and usability; we therefore seek simple and easy to understand approaches that can be used by a normal computer-illiterate home owner, not just by a trained system administrator. This position paper describes ongoing research and does not claim to have all the answers.

The Mouse Genome Informatics (MGI), resource ( www.informatics.jax.org ) has existed for over 25 years, and over this time its data content, informatics infrastructure, and user interfaces and tools have undergone dramatic changes (Eppig et al., Mamm Genome 26:272-284, 2015). Change has been driven by scientific methodological advances, rapid improvements in computational software, growth in computer hardware capacity, and the ongoing collaborative nature of the mouse genomics community in building resources and sharing data. Here we present an overview of the current data content of MGI, describe its general organization, and provide examples using simple and complex searches, and tools for mining and retrieving sets of data.

Refugee Health: An Ongoing Commitment and Challenge

Refugees represent a diverse group of displaced individuals with unique health issues and disease risks. The obstacles facing this population have their origins in war, violence, oppression, exploitation, and fear of persecution. Regardless of country of origin, a common bond exists, with refugees often confronting inadequate healthcare resources, xenophobia, discrimination, and a complex web of legal barriers in their new homelands. In many cases, the plight of refugees is multigenerational, manifesting as mental health issues, abuse, poverty, and family disruption. The health trajectory of refugees remains an ongoing commitment and challenge. PMID:29342831

Realising the economic potential of research institutions, including medical research institutes, represents a policy imperative for many Organisation for Economic Co-operation and Development nations. The assessment of research impact has consequently drawn increasing attention. Research impact assessment frameworks (RIAFs) provide a structure to assess research translation, but minimal research has examined whether alternative RIAFs realise the intended policy outcomes. This paper examines the objectives presented for RIAFs in light of economic imperatives to justify ongoing support for health and medical research investment, leverage productivity via commercialisation and outcome-efficiency gains in health systems, and ensure that translation and impact considerations are embedded into the research process. This paper sought to list the stated objectives for RIAFs, to identify existing frameworks and to evaluate whether the identified frameworks possessed the capabilities necessary to address the specified objectives. A scoping review of the literature to identify objectives specified for RIAFs, inform upon descriptive criteria for each objective and identify existing RIAFs. Criteria were derived for each objective. The capability for the existing RIAFs to realise the alternative objectives was evaluated based upon these criteria. The collated objectives for RIAFs included accountability (top-down), transparency/accountability (bottom-up), advocacy, steering, value for money, management/learning and feedback/allocation, prospective orientation, and speed of translation. Of the 25 RIAFs identified, most satisfied objectives such as accountability and advocacy, which are largely sufficient for the first economic imperative to justify research investment. The frameworks primarily designed to optimise the speed of translation or enable the prospective orientation of research possessed qualities most likely to optimise the productive outcomes from research. However, the results show that few frameworks met the criteria for these objectives. It is imperative that the objective(s) for an assessment framework are explicit and that RIAFs are designed to realise these objectives. If the objectives include the capability to pro-actively drive productive research impacts, the potential for prospective orientation and a focus upon the speed of translation merits prioritisation. Frameworks designed to optimise research translation and impact, rather than simply assess impact, offer greater promise to contribute to the economic imperatives compelling their implementation.

The main objective of the ongoing project CORDEX.be, "COmbining Regional Downscaling EXpertise in Belgium: CORDEX and Beyond", is to gather existing and ongoing Belgian research activities in the domain of climate modelling to create a coherent scientific basis for future climate services in Belgium. The project regroups 8 Belgian Institutes under a single research program of the Belgian Science Policy (BELSPO). The project involves three regional climate models: the ALARO model, the COSMO-CLM model and the MAR model running according to the guidelines of the CORDEX project and at convection permitting resolution on small domains over Belgium. The project creates a framework to address four objectives/challenges. First, this projects aims to contribute to the EURO-CORDEX project. Secondly, RCP simulations are executed at convection-permitting resolutions (3 to 5 km) on small domains. Thirdly, the output of the atmospheric models is used to drive land surface models (the SURFEX model and the Urbclim model) with urban modules, a crop model (REGCROP), a tides and storm model (COHERENS) and the MEGAN-MOHYCAN model that simulates the fluxes emitted by vegetation. Finally, one work package will translate the uncertainty present in the CORDEX database to the high-resolution output of the CORDEX.be project. The organization of the project will be presented and first results will be shown, demonstrating that convection-permitting models can add extra skill to the mesoscale version of the regional climate models, in particular regarding the extreme value statistics and the diurnal cycle.

To develop guidelines for management and treatment of maladaptive aggression in youth in the areas of psychosocial interventions, medication treatments, and side-effect management. Evidence was assembled and evaluated in a multistep process, including systematic reviews of published literature; an expert survey of recommended practices; a consensus conference of researchers, policymakers, clinicians, and family advocates; and review by the steering committee of successive drafts of the recommendations. The Center for Education and Research on Mental Health Therapeutics Treatment of Maladaptive Aggression in Youth guidelines reflect a synthesis of the available evidence, based on this multistep process. This article describes the content, rationale, and evidence for 11 recommendations. Key treatment principles include considering psychosocial interventions, such as evidence-based parent and child skills training as the first line of treatment; targeting the underlying disorder first following evidence-based guidelines; considering individual psychosocial and medical factors, including cardiovascular risk in the selection of agents if medication treatment (ideally with the best evidence base) is initiated; avoiding the use of multiple psychotropic medications simultaneously; and careful monitoring of treatment response, by using structured rating scales, as well as close medical monitoring for side effects, including metabolic changes. Treatment of children with maladaptive aggression is a "moving target" requiring ongoing assimilation of new evidence as it emerges. Based on the existing evidence, the Treatment of Maladaptive Aggression in Youth guidelines provide a framework for management of maladaptive aggression in youth, appropriate for use by primary care clinicians and mental health providers.

Objective Inefficiencies in clinical trial data collection cause delays, increase costs, and may reduce clinician participation in medical research. In this proof-of-concept study, we examine the feasibility of using point-of-care data capture for both the medical record and clinical research in the setting of a working clinical trial. We hypothesized that by doing so, we could increase reuse of patient data, eliminate redundant data entry, and minimize disruption to clinic workflow. Design We developed and used a point-of-care electronic data capture system to record data during patient visits. The standards-based system was used for clinical research and to generate the clinic note for the medical record. The system worked in parallel with data collection procedures already in place for an ongoing multicenter clinical trial. Our system was iteratively designed after analyzing case report forms and clinic notes, and observing clinic workflow patterns and business procedures. Existing data standards from CDISC and HL7 were used for database insertion and clinical document exchange. Results Our system was successfully integrated into the clinic environment and used in two live test cases without disrupting existing workflow. Analyses performed during system design yielded detailed information on practical issues affecting implementation of systems that automatically extract, store, and reuse healthcare data. Conclusion Although subject to the limitations of a small feasibility study, our study demonstrates that electronic patient data can be reused for prospective multicenter clinical research and patient care, and demonstrates a need for further development of therapeutic area standards that can facilitate researcher use of healthcare data.

The management of research data is now a major challenge for research organisations. Vast quantities of born-digital data are being produced in a wide variety of forms at a rapid rate in universities. This paper analyses the contribution of academic libraries to research data management (RDM) in the wider institutional context. In particular it: examines the roles and relationships involved in RDM, identifies the main components of an RDM programme, evaluates the major drivers for RDM activities, and analyses the key factors influencing the shape of RDM developments. The study is written from the perspective of library professionals, analysing data from 26 semi-structured interviews of library staff from different UK institutions. This is an early qualitative contribution to the topic complementing existing quantitative and case study approaches. Results show that although libraries are playing a significant role in RDM, there is uncertainty and variation in the relationship with other stakeholders such as IT services and research support offices. Current emphases in RDM programmes are on developments of policies and guidelines, with some early work on technology infrastructures and support services. Drivers for developments include storage, security, quality, compliance, preservation, and sharing with libraries associated most closely with the last three. The paper also highlights a 'jurisdictional' driver in which libraries are claiming a role in this space. A wide range of factors, including governance, resourcing and skills, are identified as influencing ongoing developments. From the analysis, a model is constructed designed to capture the main aspects of an institutional RDM programme. This model helps to clarify the different issues involved in RDM, identifying layers of activity, multiple stakeholders and drivers, and a large number of factors influencing the implementation of any initiative. Institutions may usefully benchmark their activities against the data and model in order to inform ongoing RDM activity.

Detecting and coping with disruptive shocks in Arctic marine systems: a resilience approach to place and people.

2012-02-01

It seems inevitable that the ongoing and rapid changes in the physical environment of the marine Arctic will push components of the region's existing social-ecological systems-small and large-beyond tipping points and into new regimes. Ongoing changes include warming, freshening, acidification, and alterations to food web structure. In anticipation we pose three distinct but interrelated challenges: (1) to explore existing connectivities within components of the marine system; (2) to seek indicators (if they exist) of approaching regime change through observation and modeling; and (3) to build functional resilience into existing systems through adaptation-oriented policy and to have in hand transformative options when tipping points are crossed and new development trajectories are required. Each of the above challenges is scale dependent, and each requires a much deeper understanding than we currently have of connectivity within existing systems and their response to external forcing. Here, we argue from a global perspective the need to understand the Arctic's role in an increasingly nonlinear world; then describe emerging evidence from new observations on the connectivity of processes and system components from the Canada Basin and subarctic seas surrounding northern North America; and finally posit an approach founded in "resilience thinking" to allow northern residents living in small coastal communities to participate in the observation, adaption and-if necessary-transformation of the social-ecological system with which they live.

Lyme disease is a tickborne illness that generates controversy among medical providers and researchers. One of the key topics of debate is the existence of persistent infection with the Lyme spirochete, Borrelia burgdorferi , in patients who have been treated with recommended doses of antibiotics yet remain symptomatic. Persistent spirochetal infection despite antibiotic therapy has recently been demonstrated in non-human primates. We present evidence of persistent Borrelia infection despite antibiotic therapy in patients with ongoing Lyme disease symptoms. In this pilot study, culture of body fluids and tissues was performed in a randomly selected group of 12 patients with persistent Lyme disease symptoms who had been treated or who were being treated with antibiotics. Cultures were also performed on a group of ten control subjects without Lyme disease. The cultures were subjected to corroborative microscopic, histopathological and molecular testing for Borrelia organisms in four independent laboratories in a blinded manner. Motile spirochetes identified histopathologically as Borrelia were detected in culture specimens, and these spirochetes were genetically identified as Borrelia burgdorferi by three distinct polymerase chain reaction (PCR)-based approaches. Spirochetes identified as Borrelia burgdorferi were cultured from the blood of seven subjects, from the genital secretions of ten subjects, and from a skin lesion of one subject. Cultures from control subjects without Lyme disease were negative for Borrelia using these methods. Using multiple corroborative detection methods, we showed that patients with persistent Lyme disease symptoms may have ongoing spirochetal infection despite antibiotic treatment, similar to findings in non-human primates. The optimal treatment for persistent Borrelia infection remains to be determined.

Analysis of Electric Power Board of Chattanooga Smart Grid Investment

Starke, Michael; Ollis, Ben; Glass, Jim

The deployment of a Smart Grid within the EPB electrical system has brought significant value to EPB customers and to EPB operations. The Smart Grid implementation has permitted the capability to automate many of the existing systems, increasing the overall efficiency and decreasing round trip time for many required operation functions. This has both reduced the cost of operations and increased the reliability of customer service. This boost in performance can be primarily linked to two main components: the communication network and the availability of data. The existence of a fiber communication backbone has opened numerous opportunities for EPB. Largemore » data sets from remote devices can be continuously polled and used to compute numerous metrics. The speed of communication has provided a pathway to sophisticated distribution automation that would not otherwise be possible. The data have been shown to provide a much broader view of the actual electrical system that was not previously available, opening many new opportunities in data analytics. This report documents many of the existing systems and operational features of the EPB system. Many of these systems have seen significant improvement with the deployment of Smart Grid technologies. The research behind this report found that in some cases, the value was directly computable or estimable for these enhancements. Currently, several ongoing research topics are under investigation within EPB. Through a grant from TVA, EPB is currently installing a 1.3MW solar photovoltaic system, which will be the first-generation asset owned by EPB.« less

Ongoing child welfare services: Understanding the relationship of worker and organizational characteristics to service provision.

Ongoing child welfare services are put in place after completion of the initial maltreatment investigation when there is a perceived need to mitigate the risk of future harm. The knowledge of how clinical, worker, and organizational characteristics interact with this decision to provide ongoing child welfare services is not well integrated in the research literature. Using secondary data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008, this study's primary objective is to understand the relationship of clinical, worker, and organizational characteristics to the decision to transfer a case to ongoing child welfare services and their relative contribution to the transfer decision in Canada. Findings indicate that several clinical level variables are associated with families receiving ongoing services. Additionally, organizational factors, such as type of services offered by the organization and the number of employee support programs available to workers, significantly predicted the decision to transfer a case to ongoing services. While no worker factors, such as education, amount of training, experience, or caseload, were associated with ongoing service receipt, the intraclass correlation coefficient of the final three-level parsimonious model indicated substantial clustering at the worker level. Results indicate that Canadian child welfare workers make decisions differently based on factors not available in the current study and that what would be deemed as important worker characteristics do not necessarily predict this outcome. Findings and implications for future research are discussed. Copyright © 2018 Elsevier Ltd. All rights reserved.

The Python Project: A Unique Model for Extending Research Opportunities to Undergraduate Students

Harvey, Pamela A.; Wall, Christopher; Luckey, Stephen W.; Langer, Stephen

2014-01-01

Undergraduate science education curricula are traditionally composed of didactic instruction with a small number of laboratory courses that provide introductory training in research techniques. Research on learning methodologies suggests this model is relatively ineffective, whereas participation in independent research projects promotes enhanced knowledge acquisition and improves retention of students in science. However, availability of faculty mentors and limited departmental budgets prevent the majority of students from participating in research. A need therefore exists for this important component in undergraduate education in both small and large university settings. A course was designed to provide students with the opportunity to engage in a research project in a classroom setting. Importantly, the course collaborates with a sponsor's laboratory, producing a symbiotic relationship between the classroom and the laboratory and an evolving course curriculum. Students conduct a novel gene expression study, with their collective data being relevant to the ongoing research project in the sponsor's lab. The success of this course was assessed based on the quality of the data produced by the students, student perception data, student learning gains, and on whether the course promoted interest in and preparation for careers in science. In this paper, we describe the strategies and outcomes of this course, which represents a model for efficiently providing research opportunities to undergraduates. PMID:25452492

Institutional Ethical Review and Ethnographic Research Involving Injection Drug Users: A Case Study

2014-01-01

Ethnographic research among people who inject drugs (PWID) involves complex ethical issues. While ethical review frameworks have been critiqued by social scientists, there is a lack of social science research examining institutional ethical review processes, particularly in relation to ethnographic work. This case study describes the institutional ethical review of an ethnographic research project using observational fieldwork and in-depth interviews to examine injection drug use. The review process and the salient concerns of the review committee are recounted, and the investigators’ responses to the committee’s concerns and requests are described to illustrate how key issues were resolved. The review committee expressed concerns regarding researcher safety when conducting fieldwork and the investigators were asked to liaise with the police regarding the proposed research. An ongoing dialogue with the institutional review committee regarding researcher safety and autonomy from police involvement, as well as formal consultation with a local drug user group and solicitation of opinions from external experts, helped to resolve these issues. This case study suggests that ethical review processes can be particularly challenging for ethnographic projects focused on illegal behaviours, and that while some challenges could be mediated by modifying existing ethical review procedures, there is a need for legislation that provides legal protection of research data and participant confidentiality.

Our objective was to construct a prospective high-quality and high-frequency database combining patient therapeutics and clinical variables in real time, automatically fed by the information system and network architecture available through fully electronic charting in our PICU. The purpose of this article is to describe the data acquisition process from bedside to the research electronic database. Descriptive report and analysis of a prospective database. A 24-bed PICU, medical ICU, surgical ICU, and cardiac ICU in a tertiary care free-standing maternal child health center in Canada. All patients less than 18 years old were included at admission to the PICU. None. Between May 21, 2015, and December 31, 2016, 1,386 consecutive PICU stays from 1,194 patients were recorded in the database. Data were prospectively collected from admission to discharge, every 5 seconds from monitors and every 30 seconds from mechanical ventilators and infusion pumps. These data were linked to the patient's electronic medical record. The database total volume was 241 GB. The patients' median age was 2.0 years (interquartile range, 0.0-9.0). Data were available for all mechanically ventilated patients (n = 511; recorded duration, 77,678 hr), and respiratory failure was the most frequent reason for admission (n = 360). The complete pharmacologic profile was synched to database for all PICU stays. Following this implementation, a validation phase is in process and several research projects are ongoing using this high-fidelity database. Using the existing bedside information system and network architecture of our PICU, we implemented an ongoing high-fidelity prospectively collected electronic database, preventing the continuous loss of scientific information. This offers the opportunity to develop research on clinical decision support systems and computational models of cardiorespiratory physiology for example.

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.

Population as a proxy for infrastructure in the determination of event response and recovery resource allocations

Research into modeling of the quantification and prioritization of resources used in the recovery of lifeline critical infrastructure following disruptive incidents, such as hurricanes and earthquakes, has shown several factors to be important. Among these are population density and infrastructure density, event effects on infrastructure, and existence of an emergency response plan. The social sciences literature has a long history of correlating the population density and infrastructure density at a national scale, at a country-to-country level, mainly focused on transportation networks. This effort examines whether these correlations can be repeated at smaller geographic scales, for a variety of infrastructure types,more » so as to be able to use population data as a proxy for infrastructure data where infrastructure data is either incomplete or insufficiently granular. Using the best data available, this effort shows that strong correlations between infrastructure density for multiple types of infrastructure (e.g. miles of roads, hospital beds, miles of electric power transmission lines, and number of petroleum terminals) and population density do exist at known geographic boundaries (e.g. counties, service area boundaries) with exceptions that are explainable within the social sciences literature. Furthermore, the correlations identified provide a useful basis for ongoing research into the larger resource utilization problem.« less

Do current European policies support soil multifunctionality?

NASA Astrophysics Data System (ADS)

Helming, Katharina; Glaesner, Nadia; de Vries, Wim

2017-04-01

Soils are multifunctional. Maximising one function, e.g. production of biomass, is often at the costs of the other functions, e.g. water purification, carbon sequestration, nutrient recycling, habitat provision. Sustainable soil management actually means the minimization of trade-offs between multiple soil functions. While Europe does not have a policy that explicitly focuses on soil functions, a number of policies exist in the agricultural, environmental and climate domains that may affect soil functions, in particular food production, water purification, climate change mitigation, biodiversity conservation. The objective of this study was to identify gaps and overlaps in existing EU legislation that is related to soil functions. We conducted a cross-policy analysis of 19 legislative policies at European level. Results revealed two key findings: (i) soil functions are addressed in existing legislation but with the approach to their conservation rather than their improvement. (ii) Different legislations addressed isolated soil functions but there is no policy in place that actually addressed the soil multifunctionality, which is the integrated balancing of the multitude of functions. Because soil degradation is ongoing in Europe, it raises the question whether existing legislation is sufficient for maintaining soil resources and achieving sustainable soil management. Addressing soil functions individually in various directives fails to account for the multifunctionality of soil. Here, research has a role to play to better reveal the interacting processes between soil functions and their sensitivity to soil management decisions and to translate such understanding into policy recommendation. We conclude the presentation with some insights into a research approach that integrates the soil systems into the socio-economic systems to improve the understanding of soil management pressures, soil functional reactions and their impacts on societal value systems, including resource efficiency, ecosystem services and intergenerational equity.

Abstract Background: The critical need to expand and develop the palliative care evidence base was recently highlighted by the Journal of Palliative Medicine's series of articles describing the Research Priorities in Geriatric Palliative Care. The Health and Retirement Study (HRS) is uniquely positioned to address many priority areas of palliative care research. This nationally representative, ongoing, longitudinal study collects detailed survey data every 2 years, including demographics, health and functional characteristics, information on family and caregivers, and personal finances, and also conducts a proxy interview after each subject's death. The HRS can also be linked with Medicare claims data and many other data sources, e.g., U.S. Census, Dartmouth Atlas of Health Care. Setting: While the HRS offers innumerable research opportunities, these data are complex and limitations do exist. Therefore, we assembled an interdisciplinary group of investigators using the HRS for palliative care research to identify the key palliative care research gaps that may be amenable to study within the HRS and the strengths and weaknesses of the HRS for each of these topic areas. Conclusion: In this article we present the work of this group as a potential roadmap for investigators contemplating the use of HRS data for palliative care research. PMID:24694096

The interface of self psychology, infant research, and neuroscience in clinical practice.

PubMed

Rustin, Judith

2009-04-01

This article focuses on the integration of self psychology with findings from infant research and neuroscience. While Kohut's psychology of the self provides a useful theoretical model for psychoanalytic practice, aspects of infant research and neuroscience offer specificity and nuance to basic self-psychological concepts. Kohut proposed that self-psychological psychoanalysis ameliorates derailed development through patient-analyst interaction, while a listening stance of empathic immersion begins the curative process of derailed development and sets the stage for reparative psychoanalytic work. Findings from infant research delineate much more specifically the nature of attunement both in early mother-infant and analyst-patient interactions. Findings from neuroscientific research delineate how early mother-infant experiences are encoded in implicit memory and explicates the emotional substrate of affects and feelings. This emotional substrate exists at birth and provides a means of communication both in infancy and adulthood. Additionally, infant research delineates the mutuality of the interactive process. Thus, both infant research and neuroscience add subtlety and nuance to basic self-psychological concepts. This subtlety opens up new ways of understanding patients and expands the clinical repertoire. Three clinical vignettes demonstrate how this nuance and expansion of self-psychological concepts are applied in the context of an ongoing psychoanalytic treatment.

E-Health has attracted growing interests globally. The relative lack of facilities, skills, funds and information on existing e-Health initiatives has affected progress on e-Health in Africa. To review publicly available literature on e-Health in sub-Saharan Africa (sSA) towards providing information on existing and ongoing e-Health initiatives in the region. Searches of relevant literature were conducted on Medline, EMBASE and Global Health, with search dates set from 1990 to 2016. We included studies on e-Health initiatives (prototypes, designs, or completed projects) targeting population groups in sSA. Our search returned 2322 hits, with 26 studies retained. Included studies were conducted in 14 countries across the four sub-regions in sSA (Central, East, South and West) and spreading over a 12-year period, 2002-2014. Six types of e-Health interventions were reported, with 17 studies (65 %) based on telemedicine, followed by mHealth with 5 studies (19 %). Other e-Health types include expert system, electronic medical records, e-mails, and online health module. Specific medical specialties covered include dermatology (19 %), pathology (12 %) and radiology (8 %). Successes were 'widely reported' (representing 50 % overall acceptance or positive feedbacks in a study) in 10 studies (38 %). The prominent challenges reported were technical problems, poor internet and connectivity, participants' selection biases, contextual issues, and lack of funds. E-Health is evolving in sSA, but with poorly published evidence. While we call for more quality research in the region, it is also important that population-wide policies and on-going e-Health initiatives are contextually feasible, acceptable, and sustainable.

Ongoing exposure versus intense periodic exposure to military conflict and terror attacks in Israel.

The manifestation of posttraumatic stress disorder (PTSD) symptoms in two clinical samples in Israel (N = 212) was examined. Individuals suffering ongoing exposure to shelling were compared with subjects exposed to intense periodic exposure. Elevated arousal and avoidance symptoms, but not intrusion were reported in the ongoing exposure group. When compared by age, young participants in the ongoing exposure group had significantly lower PTSD scores, whereas no differences were found between participants among the intense periodic exposure age groups. No gender differences in symptoms were found among participants from intense periodic exposure, whereas in the other ongoing group the difference was in avoidance. Results are discussed in light of past research on exposure to terrorism. Copyright © 2010 International Society for Traumatic Stress Studies.

The use of clinical trials in comparative effectiveness research on mental health.

Blanco, Carlos; Rafful, Claudia; Olfson, Mark

2013-08-01

A large body of comparative effectiveness research (CER) focuses on the use of observational and quasi-experimental approaches. We sought to examine the use of clinical trials as a tool for CER, particularly in mental health. Examination of three ongoing randomized clinical trials in psychiatry addressing issues that would pose difficulties for nonexperimental CER methods. Existing statistical approaches to nonexperimental data appear insufficient to compensate for biases that may arise when the pattern of missing data cannot be properly modeled such as when there are no standards for treatment, when affected populations have limited access to treatment, or when there are high rates of treatment dropout. Clinical trials should retain an important role in CER, particularly in cases of high disorder prevalence, large expected effect sizes, difficult-to-reach populations, or when examining sequential treatments or stepped-care algorithms. Progress in CER on mental health will require careful consideration of appropriate selection between clinical trials and nonexperimental designs and on allocation of research resources to optimally inform key treatment decisions for each patient.

Osteoarthritis is a leading cause of disability in the United States. This article describes a prioritized research agenda about osteoarthritis management developed for the Patient-Centered Outcomes Research Institute. Evidence gaps were identified by reviewing existing literature and engaging diverse stakeholders to expand and refine gaps. Stakeholders ranked evidence gaps by importance from their perspectives.Prioritized evidence gaps included the need to determine or evaluate key patient-centered outcomes; optimal duration, intensity, and frequency of nonsurgical interventions; whether the comparative effectiveness of nonsurgical interventions varies by socioeconomic factors; when and how to transition from nonsurgical to surgical interventions; effective ways to engage patients in self-management and promote long-term behavior change; standardized screening tools that improve early diagnosis; biomechanical strategies that improve symptoms; mechanisms for promoting and delivering coordinated, longitudinal care; and comparative effectiveness of nonsurgical therapies. Searches of PubMed and ClinicalTrials.gov showed many recent and ongoing studies addressing comparative effectiveness of nonsurgical interventions; relatively few of these evaluated treatments across categories (for example, drug therapy vs. weight management) or combined categories of treatment. Few studies addressed other high-priority evidence gaps.

Focus Areas: Integrative Approaches to Care The purpose of this panel discussion is to share successful efforts from a practice-based research network (PBRN) including ten integrative medicine clinics. The BraveNet PBRN includes integrative medicine clinics with academic health centers, large health systems, and a stand-alone private practice clinic. While clinical care is prioritized across all of these centers, introducing research into clinical sites oriented to providing care poses challenges that vary by clinic environment. We will highlight some of the unique issues encountered when trying to standardize data collection in sites practicing a patient-centered, whole-systems approach to healing as well as the solutions used to overcome these issues. We will present some operational solutions and data collected from the PBRN's ongoing data registry, entitled PRIMIER. The panel will engage attendees in a dialogue centering on potential for future analyses of existing results, ideas for possible upcoming studies, and creative ways to expand the PBRN data registry to include additional sites that may have expertise and interest in participating.

Ancillary study management systems: a review of needs

PubMed Central

2013-01-01

Background The valuable clinical data, specimens, and assay results collected during a primary clinical trial or observational study can enable researchers to answer additional, pressing questions with relatively small investments in new measurements. However, management of such follow-on, “ancillary” studies is complex. It requires coordinating across institutions, sites, repositories, and approval boards, as well as distributing, integrating, and analyzing diverse data types. General-purpose software systems that simplify the management of ancillary studies have not yet been explored in the research literature. Methods We have identified requirements for ancillary study management primarily as part of our ongoing work with a number of large research consortia. These organizations include the Center for HIV/AIDS Vaccine Immunology (CHAVI), the Immune Tolerance Network (ITN), the HIV Vaccine Trials Network (HVTN), the U.S. Military HIV Research Program (MHRP), and the Network for Pancreatic Organ Donors with Diabetes (nPOD). We also consulted with researchers at a range of other disease research organizations regarding their workflows and data management strategies. Lastly, to enhance breadth, we reviewed process documents for ancillary study management from other organizations. Results By exploring characteristics of ancillary studies, we identify differentiating requirements and scenarios for ancillary study management systems (ASMSs). Distinguishing characteristics of ancillary studies may include the collection of additional measurements (particularly new analyses of existing specimens); the initiation of studies by investigators unaffiliated with the original study; cross-protocol data pooling and analysis; pre-existing participant consent; and pre-existing data context and provenance. For an ASMS to address these characteristics, it would need to address both operational requirements (e.g., allocating existing specimens) and data management requirements (e.g., securely distributing and integrating primary and ancillary data). Conclusions The scenarios and requirements we describe can help guide the development of systems that make conducting ancillary studies easier, less expensive, and less error-prone. Given the relatively consistent characteristics and challenges of ancillary study management, general-purpose ASMSs are likely to be useful to a wide range of organizations. Using the requirements identified in this paper, we are currently developing an open-source, general-purpose ASMS based on LabKey Server (http://www.labkey.org) in collaboration with CHAVI, the ITN and nPOD.

Managing climate change refugia for climate adaptation

USGS Publications Warehouse

Morelli, Toni L.; Jackson, Stephen T.

2016-01-01

Refugia have long been studied from paleontological and biogeographical perspectives to understand how populations persisted during past periods of unfavorable climate. Recently, researchers have applied the idea to contemporary landscapes to identify climate change refugia, here defined as areas relatively buffered from contemporary climate change over time that enable persistence of valued physical, ecological, and socio-cultural resources. We differentiate historical and contemporary views, and characterize physical and ecological processes that create and maintain climate change refugia. We then delineate how refugia can fit into existing decision support frameworks for climate adaptation and describe seven steps for managing them. Finally, we identify challenges and opportunities for operationalizing the concept of climate change refugia. Managing climate change refugia can be an important option for conservation in the face of ongoing climate change.

Rape as a weapon of war in the Democratic Republic of the Congo.

Brown, Carly

2012-01-01

The Democratic Republic of the Congo has been appropriately acknowledged as "the rape capital of the world." While the country has been trapped in conflict, the use of rape as a weapon of war has been rampant and unyielding. The sexual violence inflicted upon women has been nothing less than brutal and destructive, physically, socially, and psychologically. This paper analyzes the use of rape as a weapon of war in the Congo, taking into context the ongoing war, cultural and social situations that facilitate its existence, and the many consequences the victims are forced to endure. Drawing information from various academic journals, articles, and field research from international organizations, this paper paints a concise picture of the sexual atrocities occurring in the Democratic Republic of the Congo.

Supercooled and glassy water: Metastable liquid(s), amorphous solid(s), and a no-man's land

NASA Astrophysics Data System (ADS)

Handle, Philip H.; Loerting, Thomas; Sciortino, Francesco

2017-12-01

We review the recent research on supercooled and glassy water, focusing on the possible origins of its complex behavior. We stress the central role played by the strong directionality of the water-water interaction and by the competition between local energy, local entropy, and local density. In this context we discuss the phenomenon of polyamorphism (i.e., the existence of more than one disordered solid state), emphasizing both the role of the preparation protocols and the transformation between the different disordered ices. Finally, we present the ongoing debate on the possibility of linking polyamorphism with a liquid-liquid transition that could take place in the no-man's land, the temperature-pressure window in which homogeneous nucleation prevents the investigation of water in its metastable liquid form.

Is victim identity in genocide a question of science or law? The scientific perspective, with special reference to Darfur.

PubMed

Komar, Debra

2008-09-01

In genocide, victims must represent an ethnic, racial, religious or national group. But is victim identity a question of science or law? Must victims be a socially recognized group or can group identity exist solely in the mind of the perpetrator? This question is relevant to the on-going crisis in Darfur. The "Arab-on-African" violence depicted in the media encompasses identities not shared by Darfurians. This study details an evaluation of victim identity in Darfur, based on field research and literature review. Darfurians are defined by subsistence strategy and economic groups are not protected under genocide law. Whether Darfur is genocide depends on whether victims must conform to scientific group classifications or need only be defined by their relationship to the perpetrators.

HIV Prevention Among Transgender Populations: Knowledge Gaps and Evidence for Action.

PubMed

Poteat, Tonia; Malik, Mannat; Scheim, Ayden; Elliott, Ayana

2017-08-01

The purpose of this review is to summarize the available evidence-based HIV prevention interventions tailored for transgender people. A limited number of evidence-based HIV prevention interventions have been tested with transgender populations. Most existing interventions target behavior change among transgender women, with only one HIV prevention program evaluated for transgender men. Studies addressing biomedical interventions for transgender women are ongoing. Few interventions address social and structural barriers to HIV prevention, such as stigma, discrimination, and poverty. Evidence-based multi-level interventions that address the structural, biomedical, and behavioral risks for HIV among transgender populations, including transgender men, are needed to address disparities in HIV prevalence. Future research should address not only pre-exposure prophylaxis uptake and condom use but also structural barriers that limit access to these prevention strategies.

Although high-throughput sequencing methods have been proposed to identify splicing branch points in the human genome, these methods can only detect a small fraction of the branch points subject to the sequencing depth, experimental cost and the expression level of the mRNA. An accurate computational model for branch point prediction is therefore an ongoing objective in human genome research. We here propose a novel branch point prediction algorithm that utilizes information on the branch point sequence and the polypyrimidine tract. Using experimentally validated data, we demonstrate that our proposed method outperforms existing methods. Availability and implementation: https://github.com/zhqingit/BPP. djguo@cuhk.edu.hk.

To strengthen the quality of HIV care and achieve improved clinical outcomes, payers, providers, and policymakers should encourage the use of patient-centered medical homes (PCMHs), building on the Ryan White CARE Act Program established in the 1990s. The rationale for a PCMH with HIV-specific expertise is rooted in clinical complexity, HIV’s social context, and ongoing gaps in HIV care. Existing Ryan White HIV/AIDS Program clinicians are prime candidates to serve HIV PCMHs, and HIV-experienced community-based organizations can play an important role. Increasingly, state Medicaid programs are adopting a PCMH care model to improve access and quality to care. Stakeholders should consider several important areas for future action and research with regard to development of the HIV PCMH. PMID:24832431

Flavivirus RNAi suppression: decoding non-coding RNA.

PubMed

Pijlman, Gorben P

2014-08-01

Flaviviruses are important human pathogens that are transmitted by invertebrate vectors, mostly mosquitoes and ticks. During replication in their vector, flaviviruses are subject to a potent innate immune response known as antiviral RNA interference (RNAi). This defense mechanism is associated with the production of small interfering (si)RNA that lead to degradation of viral RNA. To what extent flaviviruses would benefit from counteracting antiviral RNAi is subject of debate. Here, the experimental evidence to suggest the existence of flavivirus RNAi suppressors is discussed. I will highlight the putative role of non-coding, subgenomic flavivirus RNA in suppression of RNAi in insect and mammalian cells. Novel insights from ongoing research will reveal how arthropod-borne viruses modulate innate immunity including antiviral RNAi. Copyright © 2014 Elsevier B.V. All rights reserved.

Ongoing research in occupational health and environmental epidemiology in developing countries

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

Levy, B.S.; Kjellstrom, T.; Forget, G.

Research in occupational health and environmental epidemiology can play an important role in furthering our understanding of occupational and environmental health problems. Research guides us in the recognition, management, and prevention of health problems. However, in developing countries, where rates of occupational and environmental illnesses and injuries are higher and where these problems are often more severe than in developed countries, research capabilities are less developed. In mid-1990, a project was undertaken to (a) document ongoing research in occupational health and environmental epidemiology in developing countries, (b) facilitate the exchange of information among researchers in this field, (c) stimulate research,more » and (d) avoid unnecessary duplication among researchers in this field. A questionnaire was mailed, the purpose of which was to learn the current status of research in developing countries and to develop a directory of such ongoing research. The questionnaire was sent to 1,528 individuals. Of the 500 research projects identified, 77% were investigating chemical hazards; 26%, physical hazards; 10%, biological hazards; 10%, psychosocial hazards (some projects addressed multiple hazards). The chemical hazards studied most frequently were dusts, pesticides, and lead. The greatest number of research projects were identified in China, India, Brazil, Korea, and Thailand. Most projects were descriptive or cross-sectional epidemiologic studies or industrial hygiene or exposure-assessment studies. The World Health Organization has published a directory of the specific research projects that were identified in this survey.« less

2017-09-18

The clinical research enterprise is not producing the evidence decision makers arguably need in a timely and cost effective manner; research currently involves the use of labor-intensive parallel systems that are separate from clinical care. The emergence of pragmatic clinical trials (PCTs) poses a possible solution: these large-scale trials are embedded within routine clinical care and often involve cluster randomization of hospitals, clinics, primary care providers, etc. Interventions can be implemented by health system personnel through usual communication channels and quality improvement infrastructure, and data collected as part of routine clinical care. However, experience with these trials is nascent and best practices regarding design operational, analytic, and reporting methodologies are undeveloped. To strengthen the national capacity to implement cost-effective, large-scale PCTs, the Common Fund of the National Institutes of Health created the Health Care Systems Research Collaboratory (Collaboratory) to support the design, execution, and dissemination of a series of demonstration projects using a pragmatic research design. In this article, we will describe the Collaboratory, highlight some of the challenges encountered and solutions developed thus far, and discuss remaining barriers and opportunities for large-scale evidence generation using PCTs. A planning phase is critical, and even with careful planning, new challenges arise during execution; comparisons between arms can be complicated by unanticipated changes. Early and ongoing engagement with both health care system leaders and front-line clinicians is critical for success. There is also marked uncertainty when applying existing ethical and regulatory frameworks to PCTS, and using existing electronic health records for data capture adds complexity.

Preceptor/mentor education: a world of possibilities through e-learning technology.

Preceptorship/mentorship is designed to socialize students into the nursing profession, promote their confidence/competence and foster their critical thinking ability. In today's global context, opportunities exist for local, rural, national and international student placements which provide exciting and mutually rewarding preceptorship experiences. Despite the recognized value of those involved in preceptorship/mentorship, however, little progress has been made regarding the development of an infrastructure that effectively supports their ongoing education. This project, piloted from October 2008 to February 2009, leveraged our established research and teaching experience in preceptorship with technologies that allowed us to create an accessible and engaging e-learning space designed to support preceptors in a seamless fashion, improve the quality of the student preceptorship and enhance professional teaching capacity. A purposive sample of 25 preceptors was selected with a total of 18 preceptors successfully completing the five month program. Upon completion, participants were surveyed and individually interviewed. Data analysis revealed the program to be informative, supportive and highly valued. Knowledge derived from this study can: a) further enrich the substantive nature and infrastructure of online preceptor education; and b) contribute to clarifying best practices for preceptor support, facilitation, and ongoing professional development with a view to enhancing the preceptorship experience.

A Swedish multi-centre study of women requesting an induced abortion. The Screen Questionnaire - Posttraumatic Stress Disorder was used for research diagnoses of PTSD and PTSS. Anxiety and depressive symptoms were evaluated by the Hospital Anxiety and Depression Scale (HADS). Of the 1514 respondents, almost half reported traumatic experiences. Lifetime- and point prevalence of PTSD were 7% (95% confidence interval [CI]: 5.8-8.5) and 4% (95% CI: 3.1-5.2), respectively. The prevalence of PTSS was 23% (95% CI: 21.1-25.4). Women who reported symptoms of anxiety or depression when requesting abortion were more likely to have ongoing PTSD or PTSS. Also single-living women and smokers displayed higher rates of ongoing PTSD. Although PTSD is rare among women who request an induced abortion, a relatively high proportion suffers from PTSS. Abortion seeking women with trauma experiences and existing or preexisting mental disorders need more consideration and alertness when counselled for termination.

Country, climate change adaptation and colonisation: insights from an Indigenous adaptation planning process, Australia.

Nursey-Bray, Melissa; Palmer, Robert

2018-03-01

Indigenous peoples are going to be disproportionately affected by climate change. Developing tailored, place based, and culturally appropriate solutions will be necessary. Yet finding cultural and institutional 'fit' within and between competing values-based climate and environmental management governance regimes remains an ongoing challenge. This paper reports on a collaborative research project with the Arabana people of central Australia, that resulted in the production of the first Indigenous community-based climate change adaptation strategy in Australia. We aimed to try and understand what conditions are needed to support Indigenous driven adaptation initiatives, if there are any cultural differences that need accounting for and how, once developed they be integrated into existing governance arrangements. Our analysis found that climate change adaptation is based on the centrality of the connection to 'country' (traditional land), it needs to be aligned with cultural values, and focus on the building of adaptive capacity. We find that the development of climate change adaptation initiatives cannot be divorced from the historical context of how the Arabana experienced and collectively remember colonisation. We argue that in developing culturally responsive climate governance for and with Indigenous peoples, that that the history of colonisation and the ongoing dominance of entrenched Western governance regimes needs acknowledging and redressing into contemporary environmental/climate management.

On the road to eliminate malaria in Sri Lanka: lessons from history, challenges, gaps in knowledge and research needs

PubMed Central

2014-01-01

Malaria is one of the most important tropical diseases that has caused devastation throughout the history of mankind. Malaria eradication programmes in the past have had many positive effects but failed to wipe out malaria from most tropical countries, including Sri Lanka. Encouraged by the impressive levels of reduction in malaria case numbers during the past decade, Sri Lanka has launched a programme to eliminate malaria by year 2014. This article reviews the historical milestones associated with the malaria eradication programme that failed subsequently and the events that led to the launch of the ongoing malaria elimination plans at national-level and its strategies that are operational across the entire country. The existing gaps in knowledge are also discussed together with the priority areas for research to fill in these gaps that are posing as challenges to the envisaged goal of wiping out malaria from this island nation.

Space Nutrition

Smith, Scott M.

2009-01-01

Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

What do we know about maternal-fetal attachment?

PubMed

Shieh, C; Kravitz, M; Wang, H H

2001-09-01

A review of the literature suggests that there are three critical attributes related to the concept of maternal-fetal attachment, including cognitive, affective, and altruistic attachment. Cognitive attachment is the desire to know the baby. Affective attachment is the pleasure associated with thoughts of or interaction with the fetus. Altruistic attachment refers to a desire to protect the unborn child. Existing measurements on maternal-fetal attachment are developed based on low-risk and white pregnant women and previous research has not yet resulted in a consistent theoretical model. Future research should focus on development of culturally sensitive instruments and combining qualitative and quantitative measures to broaden theoretical understanding of the concept. Nursing assessment of maternal-fetal attachment is an on-going process. The nurse's role is to reassure those who have developed attachment to their fetuses and to motivate those who are unaware of or unconcerned about their attachment to their fetuses. Collecting data from different attributes of attachment helps nurses identify each woman's attachment patterns and areas of concern.

Cancer represents a leading cause of death whose incidence is steadily increasing worldwide due to the population aging. The Global Health Observatory of the World Health Organization reported that approximately 13% of all deaths are caused by cancer. In the 2012 the estimated total number of cancer deaths was 1.75 million, 56% in men and 44% in women. Gender is recognized to play a role in cancer incidence, progression and response to therapy. Besides anatomical and hormonal disparities, genetic differences should be considered when assessing the effects of gender on cancer. Accumulating evidence also support the existence of sex-driven differences in immune responses. Until today clinical trials and research in animal models have been gender unbalanced. In consideration of the differences between sexes observed in cancer, sex should represent an important stratification factor to be included in all randomized clinical trials for a better understanding of biological differences between men and women, which may yield improved targeted therapies.

The objective of this study was to evaluate the factor structure, validity, and reliability of the Compulsive Exercise Test (CET) in an adolescent clinical eating disorder population. The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project, a prospective ongoing registry study comprising consecutive pediatric tertiary eating disorder referrals. Adolescents (N=104; 12-17years) with eating disorders completed the CET and other measures. Factor structure, convergent validity, and internal consistency were evaluated. Despite failing to identify a factor structure, the study provided clear evidence of the multidimensionality of the measure. The total score correlated significantly with measures of eating pathology, perfectionism, and frequency of exercise for shape and weight control (r=0.32-0.70, ps<0.05). More research into the multidimensional nature of compulsive exercise in clinical populations is needed. Further, research into compulsive exercise offers promise as an addition to existing cognitive behavioral models and treatments for eating disorders. Copyright © 2014 Elsevier Ltd.

Toward University Modeling Instruction—Biology: Adapting Curricular Frameworks from Physics to Biology

PubMed Central

Manthey, Seth; Brewe, Eric

2013-01-01

University Modeling Instruction (UMI) is an approach to curriculum and pedagogy that focuses instruction on engaging students in building, validating, and deploying scientific models. Modeling Instruction has been successfully implemented in both high school and university physics courses. Studies within the physics education research (PER) community have identified UMI's positive impacts on learning gains, equity, attitudinal shifts, and self-efficacy. While the success of this pedagogical approach has been recognized within the physics community, the use of models and modeling practices is still being developed for biology. Drawing from the existing research on UMI in physics, we describe the theoretical foundations of UMI and how UMI can be adapted to include an emphasis on models and modeling for undergraduate introductory biology courses. In particular, we discuss our ongoing work to develop a framework for the first semester of a two-semester introductory biology course sequence by identifying the essential basic models for an introductory biology course sequence.

Polyploidization is a key driving force that plays a vital role in the evolution of higher plants. Autopolyploid plants often demonstrate altered physiology phenomena due to the different genome composition and gene expression patterns. For example, autopolyploid plants are more resistant to stresses than their homologous diploid ancestors. Soil salinity and secondary salinization are two vital factors affecting crop production which severely limit the sustainable development of agriculture in China. Polyploid plants are important germplasm resources in crop genetic improvement due to their higher salt tolerance. Revealing the mechanism of salt tolerance in homologous plants will provide a foundation for breeding new plants with improved salt resistance. In this review, we describe the existing and ongoing characterization of the mechanism of salt tolerance in autopolyploid plants, including the salt tolerance evolution, physiology, biochemistry, cell structure and molecular level researches. Finally, we also discuss the prospects in this field by using polyploid watermelon as an example, which will be helpful in polyploid research and plant breeding.

ANGWIN (ANrctic Gravity Wave Instrument Network) is a new "scientist driven" research program designed to develop and utilize a network of Antarctic atmospheric gravity wave observatories, operated by different nations working together in a spirit of close scientific collaboration. Our research plan has brought together colleagues from several international institutions, all with a common goal to better understand the large "continental-scale" characteristics and impacts of gravity waves on the Mesosphere and Lower Thermosphere (MLT) environment over Antarctica. ANGWIN combines complementary measurements obtained using new and existing aeronomy instrumentation with new modeling capabilities. To date, our activities have focused on developing coordinated airglow image data of gravity waves in the MLT region at the following sites: McMurdo (US), Syowa (Japan), Davis (Australia), Halley (UK), Rothera (UK), and Comandante Ferraz (Brazil). These are all well-established international research stations that are uniformly distributed around the continental perimeter, and together with ongoing measurements at South Pole Station they provide unprecedented coverage of the Antarctic gravity wave field and its variability during the extended polar winter season. This presentation introduces the ANGWIN program and research goals, and presents first results on trans-Antarctic wave propagation using coordinated measurements during the winter season 2011. We also discuss future plans for the development of this exciting program for Antarctic research.

Biological research of Sus scrofa, the domestic pig, is of immediate relevance for food production sciences, and for developing pig as a model organism for human biomedical research. Publicly available data repositories play a fundamental role for all biological sciences, and protein data repositories are in particular essential for the successful development of new proteomic methods. Cumulative proteome data repositories, including the PeptideAtlas, provide the means for targeted proteomics, system-wide observations, and cross-species observational studies, but pigs have so far been underrepresented in existing repositories. We here present a significantly improved build of the Pig PeptideAtlas, which includes pig proteome data from 25 tissues and three body fluid types mapped to 7139 canonical proteins. The content of the Pig PeptideAtlas reflects actively ongoing research within the veterinary proteomics domain, and this article demonstrates how the expression of isoform-unique peptides can be observed across distinct tissues and body fluids. The Pig PeptideAtlas is a unique resource for use in animal proteome research, particularly biomarker discovery and for preliminary design of SRM assays, which are equally important for progress in research that supports farm animal production and veterinary health, as for developing pig models with relevance to human health research. © 2015 WILEY-VCH Verlag GmbH & Co.

A growing number of pulmonary and critical care medicine fellowship programs in the United States offer global health training opportunities. Formal, integrated global health programs within pulmonary and critical care fellowships are relatively new but are built on principles and ideals of global health that focus on the mutually beneficial exchange of knowledge and social justice. Although core competencies consistent with these overarching themes in global health education have not been formalized for pulmonary and critical care trainees, relevant competency areas include clinical knowledge, international research training, cultural competency, and clinical and research capacity building. Existing global health education in U.S. pulmonary and critical care medicine training programs can generally be classified as one of three different models: integrated global health tracks, global health electives, and additional research years. Successful global health education programs foster partnerships and collaborations with international sites that emphasize bidirectional exchange. This bidirectional exchange includes ongoing, equitable commitments to mutual opportunities for training and professional development, including a focus on the particular knowledge and skill sets critical for addressing the unique priorities of individual countries. However, barriers related to the availability of mentorship, funding, and dedicated time exist to expanding global health education in pulmonary and critical care medicine. The implementation of global health training within pulmonary and critical care medicine programs requires continued optimization, but this training is essential to prepare the next generation of physicians to address the global aspects of respiratory disease and critical illness.

It is well recognized that management of wastewater and sludge is a critical environmental issue in many countries. Wastewater treatment and sludge production take place under different technical, economic, and social contexts, thus requiring different approaches and involving different solutions. In most cases, a regular and environmentally safe wastewater treatment and associated sludge management requires the development of realistic and enforceable regulations, as well as treatment systems appropriate to local circumstances. The main objective of this paper is to provide useful information about the current wastewater and sludge treatment, management, regulations, and research in Oman. Based on the review and discussion, the wastewater treatment and sludge management in Oman has been evolving over the years. Further, the land application of sewage sludge should encourage revision of existing standards, regulations, and policies for the management and beneficial use of sewage sludge in Oman. Wastewater treatment and sludge management in Oman have been evolving over the years. Sludge utilization has been a challenge due to its association with human waste. Therefore, composting of sewage sludge is the best option in agriculture activities. Sludge and wastewater utilization can add up positively in the economic aspects of the country in terms of creating jobs and improving annual income rate. The number of research projects done on wastewater reuse and other ongoing ones related to the land application of sewage sludge should encourage revision of existing standards, regulations, and policies for the management and beneficial use of sewage sludge in Oman.

Acquiring accurate information on the spatio-temporal variability of soil moisture content (SM) and evapotranspiration (ET) is of key importance to extend our understanding of the Earth system's physical processes, and is also required in a wide range of multi-disciplinary research studies and applications. The utility and applicability of Earth Observation (EO) technology provides an economically feasible solution to derive continuous spatio-temporal estimates of key parameters characterising land surface interactions, including ET as well as SM. Such information is of key value to practitioners, decision makers and scientists alike. The PREMIER-EO project recently funded by High Performance Computing Wales (HPCW) is a research initiative directed towards the development of a better understanding of EO technology's present ability to derive operational estimations of surface fluxes and SM. Moreover, the project aims at addressing knowledge gaps related to the operational estimation of such parameters, and thus contribute towards current ongoing global efforts towards enhancing the accuracy of those products. In this presentation we introduce the PREMIER-EO project, providing a detailed overview of the research aims and objectives for the 1 year duration of the project's implementation. Subsequently, we make available the initial results of the work carried out herein, in particular, related to an all-inclusive and robust evaluation of the accuracy of existing operational products of ET and SM from different ecosystems globally. The research outcomes of this project, once completed, will provide an important contribution towards addressing the knowledge gaps related to the operational estimation of ET and SM. This project results will also support efforts ongoing globally towards the operational development of related products using technologically advanced EO instruments which were launched recently or planned be launched in the next 1-2 years.

Objectives A large body of research on comparative effectiveness research (CER) focuses on the use of observational and quasi-experimental approaches. We sought to examine the use of clinical trials as a tool for CER, particularly in mental health. Study Design and Setting Examination of three ongoing randomized clinical trials in psychiatry that address issues which would pose difficulties for non-experimental CER methods. Results Existing statistical approaches to non-experimental data appear insufficient to compensate for biases that may arise when the pattern of missing data cannot be properly modeled such as when there are no standards for treatment, when affected populations have limited access to treatment, or when there are high rates of treatment dropout. Conclusions Clinical trials should retain an important role in CER, particularly in cases of high disorder prevalence, large expected effect sizes, difficult to reach populations or when examining sequential treatments or stepped-care algorithms. Progress in CER in mental health will require careful consideration of appropriate selection between clinical trials and non-experimental designs and on allocation of research resources to optimally inform key treatment decisions for each individual patient.

This document presents a second report from the Atmospheric Effects of Stratospheric Aircraft (AESA) component of NASA's High-Speed Research Program (HSRP). This document presents a second report from the Atmospheric Effects of Stratospheric Aircraft (AESA) component of NASA's High Speed Research Program (HSRP). Market and technology considerations continue to provide an impetus for high-speed civil transport research. A recent United Nations Environment Program scientific assessment has shown that considerable uncertainty still exists about the possible impact of aircraft on the atmosphere. The AESA was designed to develop the body of scientific knowledge necessary for the evaluation of the impact of stratospheric aircraft on the atmosphere. The first Program report presented the basic objectives and plans for AESA. This second report presents the status of the ongoing research as reported by the principal investigators at the second annual AESA Program meeting in May 1992: Laboratory studies are probing the mechanism responsible for many of the heterogeneous reactions that occur on stratospheric particles. Understanding how the atmosphere redistributes aircraft exhaust is critical to our knowing where the perturbed air will go and for how long it will remain in the stratosphere. The assessment of fleet effects is dependent on the ability to develop scenarios which correctly simulate fleet operations.

Reusable data in public health data-bases-problems encountered in Danish Children's Database.

Denmark have unique health informatics databases e.g. "The Children's Database", which since 2009 holds data on all Danish children from birth until 17 years of age. In the current set-up a number of potential sources of errors exist - both technical and human-which means that the data is flawed. This gives rise to erroneous statistics and makes the data unsuitable for research purposes. In order to make the data usable, it is necessary to develop new methods for validating the data generation process at the municipal/regional/national level. In the present ongoing research project, two research areas are combined: Public Health Informatics and Computer Science, and both ethnographic as well as system engineering research methods are used. The project is expected to generate new generic methods and knowledge about electronic data collection and transmission in different social contexts and by different social groups and thus to be of international importance, since this is sparsely documented in the Public Health Informatics perspective. This paper presents the preliminary results, which indicate that health information technology used ought to be subject for redesign, where a thorough insight into the work practices should be point of departure.

Obesity impacts the U.S. military by affecting the health and readiness of active duty service members and their families. Preventing Obesity in Military Communities (POMC) is a comprehensive research program within Patient Centered Medical Homes (PCMHs) in three Military Training Facilities. This paper describes three pilot randomized controlled trials that target critical high risk periods for unhealthy weight gain from birth to young adulthood: (1) pregnancy and early infancy (POMC-Mother-Baby), (2) adolescence (POMC-Adolescent), and (3) the first tour of duty after boot camp (POMC-Early Career). Each study employs a two-group randomized treatment or prevention program with follow up. POMC offers a unique opportunity to bring together research and clinical expertise in obesity prevention to develop state-of-the-art programs within PCMHs in Military Training Facilities. This research builds on existing infrastructure that is expected to have immediate clinical benefits to DoD and far-reaching potential for ongoing collaborative work. POMC may offer an economical approach for widespread obesity prevention, from conception to young adulthood, in the U.S. military as well as in civilian communities. PMID:25648176

Peer support for people with chronic conditions in rural areas: a scoping review.

PubMed

Lauckner, Heidi M; Hutchinson, Susan L

2016-01-01

Chronic conditions are a growing healthcare concern. People living in rural regions are particularly affected because many barriers exist to accessing services and supports. Peer support for chronic condition self-management, where people living with chronic conditions learn about how to care for themselves and maintain their health from people also living with chronic conditions, is one approach gaining recognition. What remains unknown are the unique challenges and strategies associated with peer support for chronic condition self-management in rural contexts. In order to inform the development of peer supports in the authors' local context in rural eastern Canada, a scoping review was undertaken to discover community-based peer support initiatives for adults in rural settings living with chronic conditions. The authors followed established scoping review methods to answer the research question What is known from the existing literature about the key features and potential formats of community-based peer support initiatives for adults living with chronic conditions in rural settings? Six databases (CINAHL, PubMed, Sociological Abstracts, Embase, Cochrane Libraries and PsycInfo) were searched using the following concepts: chronic conditions, peer support, community-based and rural context. Two researchers reviewed the titles and/or abstracts of the 1978 articles retrieved from the initial search to include articles that were in English, published in 2000 to 2014, and that explicitly discussed rural programs/interventions with peers that were community-based. The initial screen excluded 1907 articles, leaving 71 articles, which were read by two research members in light of the inclusion/exclusion criteria. Thirteen articles representing 10 separate programs were included and analyzed using qualitative content analysis. Included programs were from the USA, Australia and Canada. A range of formats (telecommunications only, in-person meetings only, or a combination of both) were used. Peer leaders had varied experiences with chronic conditions and received training in content and facilitation skills. Peer leaders were provided with ongoing support. Program participants received training on chronic conditions, and programs provided opportunities for social support and the development of new skills. Programs focused on creating social connections, reducing stigma, ensuring relevance and promoting empowerment. Of the nine programs that reported outcomes, eight reported positive outcomes and one reported mixed results. Consistent with the extant literature, the programs identified unique issues faced by people with chronic conditions in rural areas that these programs addressed. The key findings of this scoping review are as follows: 1. A combination of telecommunications with some face-to-face meetings can support the accessibility of peer support programs in rural areas. 2. Core elements of these programs are the provision of social support and skill development. 3. Peer leaders benefit from skills training and ongoing support. 4. Sustainability of such programs is complex and requires multiple strategies. Cultural relevance, ongoing support and the use of telecommunications were key features of rural peer support programs. Guiding questions to facilitate a community consultation around these findings are provided. Peer support chronic condition self-management programs require further research.

On July 10, 2007, the former Homestake Mine, Lead, South Dakota, was selected as the development site for the Deep Underground Science and Engineering Laboratory, to become the Sanford Underground Science and Engineering Laboratory at Homestake. Work on refurbishment and certification of the Ross Shaft began in August 2007 to effect pumping of water that had reached the 5000 level in late July. Completion of this work will allow a physics and geosciences laboratory to be constructed on the 4,850 ft level (1,478 m from the surface). Concurrent with reentry operations, several earth science research activities have been initiated. These early activities are as follows: (1) Seismic monitoring system: Accelerometers will be installed in surface boreholes and underground drifts as they become available as a result of the reentry work. (2) Evaluation of the 300 level (91 m), which has multiple locations for horizontal access, is ongoing. This near- surface level, with varying overburden thicknesses, offers excellent opportunities to investigate the "critical zone" in terms of hydrology, ecology, and geochemistry, yielding measurements of both moisture and carbon fluxes to evaluate fluid exchanges with the atmosphere. (3) Water and soil samples were collected in the Ross Shaft as part of the first reentry work. Molecular survey of microbial diversity showed the presence of mesophilic and thermophilic cellulose-degrading microorganisms. (4) Supercritical carbon dioxide injection experiments are being planned that will take advantage of three pairs of existing, nearly vertical, open 8-inch (0.2 m) boreholes that are easily accessible from the Ross Shaft. The candidate holes are located between the 1550 and the 2900 levels and are between 90 to 180 m in length (5) Monitoring of the response of the water during the dewatering operations will be facilitated by the use of existing boreholes. Ultimately, the dewatering operation provide access to the 8000 level (depth of 2,438 m), the deepest level. These five examples of ongoing research activities should provide a basis for many other earth science and engineering investigations at this multilevel facility, which already has extensive underground workings. These examples address different aspects of three main themes identified as important by deep underground research communities: restless earth for geo-science, ground truth for geo-engineering, and dark life for geo-microbiology.

The TRIDEC Project: Future-Saving FOSS GIS Applications for Tsunami Early Warning

NASA Astrophysics Data System (ADS)

Loewe, P.; Wächter, J.; Hammitzsch, M.

2011-12-01

The Boxing Day Tsunami of 2004 killed over 240,000 people in 14 countries and inundated the affected shorelines with waves reaching heights up to 30m. This natural disaster coincided with an information catastrophy, as potentially life-saving early warning information existed, yet no means were available to deliver it to the communities under imminent threat. Tsunami Early Warning Capabilities have improved in the meantime by continuing development of modular Tsunami Early Warning Systems (TEWS). However, recent tsunami events, like the Chile 2010 and the Tohoku 2011 tsunami demonstrate that the key challenge for ongoing TEWS research on the supranational scale still lies in the timely issuing of reliable early warning messages. Since 2004, the GFZ German Research Centre for Geosciences has built up expertise in the field of TEWS. Within GFZ, the Centre for GeoInformation Technology (CEGIT) has focused its work on the geoinformatics aspects of TEWS in two projects already: The German Indonesian Tsunami Early Warning System (GITEWS) funded by the German Federal Ministry of Education and Research (BMBF) and the Distant Early Warning System (DEWS), a European project funded under the sixth Framework Programme (FP6). These developments are continued in the TRIDEC project (Collaborative, Complex, and Critical Decision Processes in Evolving Crises) funded under the European Union's seventh Framework Programme (FP7). This ongoing project focuses on real-time intelligent information management in Earth management and its long-term application. All TRIDEC developments are based on Free and Open Source Software (FOSS) components and industry standards where-ever possible. Tsunami Early Warning in TRIDEC is also based on mature system architecture models to ensure long-term usability and the flexibility to adapt to future generations of Tsunami sensors. All open source software produced by the project consortium are foreseen to be published on FOSSLAB, a publicly available software repository provided by CEGIT. FOSSLAB serves as a platform for the development of FOSS projects in geospatial context, allowing to save, advance and reuse results achieved in previous and on-going project activities and enabling further development and collaboration with a wide community including scientists, developers, users and stakeholders. FOSSLABs potential to preserve and advance existing best practices for reuse in new scenarios is documented by a first case study: For TEWS education and public outreach a comprehensive approach to generate high resolution globe maps was compiled using GRASS GIS and the POV-Ray rendering software. The task resulted in the merging of isolated technical know-how into publicly available best practices, which had been previously maintained in disparate GIS- and rendering communities. Beyond the scope of TRIDEC, FOSSLAB constitutes an umbrella encompassing several geoinformatics-related activities, such as the documentation of Best Practices for experiences and results while working with Spatial Data Infrastructures (SDI), Geographic Information Systems (GIS), Geomatics, and future spatial processing on Computation Clusters and in Cloud Computing.

We discuss implications for instructors and researchers interested in improving students' science literacy scores and diagnosing alternative beliefs.

High-Resolution X-Ray Imaging of Colliding Radio-Jet Galaxies

NASA Technical Reports Server (NTRS)

Born, Kirk D.; Whitmore, Brad

1996-01-01

We received ROSAT data for four program objects:3C31,3C278,3C449,and NGC1044. The first three sources were observed with the ROSAT HRI instrument. Our plan was to use the HRI to image the hot gas distribution in a few pairs of strongly disturbed interacting elliptical galaxies which are also strong radio sources having a bent-jet source morphology. The PSPC was used for NGC1044 in order to obtain a flux measurement to use in planning future High Resolution Imager (HRI) observations of that source. Though we never requested such HRI observations of NGC1044, others have used those archival PSPC data from our project for other research projects and analyses. The goal of the program was to elucidate the detailed distribution of hot gas into which the jets flow. The X-ray data were consequently analyzed in conjunction with existing VLA radio maps, optical broad-band and H-alpha Charge Couple device (CCD) images, and optical kinematic data to constrain models for the propagation of ballistic jets in interacting galaxies. We were able to test and validate the claimed causal connection between tidal interaction, the presence of gas, and the onset of activity in galaxies. The full multi-wavelength multi-observatory analyses described here are still on-going and will be published in the future. Because of the relevance of this research to on-going work in the field of active galaxies, the grant was used to support travel to several scientific meetings where our x-ray analysis, numerical modeling, and related radio results were presented and discussed.

Access to improved water supply and sanitation is poor in low-income and middle-income countries. Persons living with HIV/AIDS (PLHIV) experience more severe diarrhea, hospitalizations, and deaths from diarrhea because of waterborne pathogens than immunocompetent populations, even when on antiretroviral therapy (ART). We examined the existing literature on the impact of water, sanitation, and hygiene (WASH) interventions on PLHIV for these outcomes: (1) mortality, (2) morbidity, (3) retention in HIV care, (4) quality of life, and (5) prevention of ongoing HIV transmission. Cost-effectiveness was also assessed. Relevant abstracts and articles were gathered, reviewed, and prioritized by thematic outcomes of interest. Articles meeting inclusion criteria were summarized in a grid for comparison. We reviewed 3355 citations, evaluated 132 abstracts, and read 33 articles. The majority of the 16 included articles focused on morbidity, with less emphasis on mortality. Contaminated water, lack of sanitation, and poor hygienic practices in homes of PLHIV increase the risk of diarrhea, which can result in increased viral load, decreased CD4 counts, and reduced absorption of nutrients and antiretroviral medication. We found WASH programming, particularly water supply, household water treatment, and hygiene interventions, reduced morbidity. Data were inconclusive on mortality. Research gaps remain in retention in care, quality of life, and prevention of ongoing HIV transmission. Compared with the standard threshold of 3 times GDP per capita, WASH interventions were cost-effective, particularly when incorporated into complementary programs. Although research is required to address behavioral aspects, evidence supports that WASH programming is beneficial for PLHIV.

Peace Corps Partnered Health Services Implementation Research in Global Health: Opportunity for Impact

Background: There is abundant evidence of the affordable, life-saving interventions effective at the local primary health care level in low- and middle-income countries (LMICs). However, the understanding of how to deliver those interventions in diverse settings is limited. Primary healthcare services implementation research is needed to elucidate the contextual factors that can influence the outcomes of interventions, especially at the local level. US universities commonly collaborate with LMIC universities, communities, and health system partners for health services research but common barriers exist. Current challenges include the capacity to establish an ongoing presence in local settings in order to facilitate close collaboration and communication. The Peace Corps is an established development organization currently aligned with local health services in many LMICs and is well-positioned to facilitate research partnerships. This article explores the potential of a community–Peace Corps–academic partnership approach to conduct local primary healthcare services implementation research. Discussion: The Peace Corps is well positioned to offer insights into local contextual factors because volunteers work closely with local leaders, have extensive trust within local communities, and have an ongoing, constant, well-integrated presence. However, the Peace Corps does not routinely conduct primary healthcare services implementation research. Universities, within the United States and locally, could benefit from the established resources and trust of the Peace Corps to conduct health services implementation research to advance access to local health services and further the knowledge of real world application of local health services in a diversity of settings. The proposed partnership would consist of (1) a local community advisory board and local health system leaders, (2) Peace Corps volunteers, and (3) a US-LMIC academic institutional collaboration. Within the proposed partnership approach, the contributions of each partner are as follows: the local community and health system leadership guides the work in consideration of local priorities and context; the Peace Corps provides logistical support, community expertise, and local trust; and the academic institutions offer professional technical and public health educational and training resources and research support. Conclusion: The Peace Corps offers the opportunity to enhance a community-academic partnership in LMICs through community-level guidance, logistical assistance, and research support for community based participatory primary health-care services implementation research that addresses local primary healthcare priorities.

Looney, B; Dawn S. Kaback, D; Eugene L. LeBoeuf, E

Beginning in 2006, the US Department of Energy (DOE) supported nine applied research projects to improve the protection of the Columbia River and mitigate the impacts of Hanford Site groundwater. These projects were funded through a supplemental Congressional budget allocation, and are now in various stages of completion in accordance with the research plans. The DOE Office of Environmental Management Groundwater and Soil Cleanup Technologies (EM-22) sponsored a technical peer review meeting for these projects in Richland WA, July 28-31, 2008. The overall objective of the peer review is to provide information to support DOE decisions about the status andmore » potential future application of the various technologies. The charge for the peer review panel was to develop recommendations for each of the nine 'technologies'. Team members for the July 2008 review were Brian Looney, Gene LeBoeuf, Dawn Kaback, Karen Skubal, Joe Rossabi, Paul Deutsch, and David Cocke. Previous project reviews were held in May 2007 and March-May of 2006. The team used the following four rating categories for projects: (a) Incorporate the technology/strategy in ongoing and future EM activities; (b) Finish existing scope of applied research and determine potential for EM activities when research program is finished; (c) Discontinue current development activities and do not incorporate technology/strategy into ongoing and future EM activities unless a significant and compelling change in potential viability is documented; and (d) Supplement original funded work to obtain the data needed to support a DOE decision to incorporate the technology into ongoing and future EM activities. The supplemental funding portfolio included two projects that addressed strontium, five projects that addressed chromium, one project that addressed uranium and one project that addressed carbon tetrachloride. The projects ranged from in situ treatment methods for immobilizing contaminants using chemical-based methods such as phosphate addition, to innovative surface treatment technologies such as electrocoagulation. Total funding for the nine projects was $9,900,000 in fiscal year (FY) 2006 and $2,000,000 in FY 2007. At the Richland meeting, the peer reviewers provided a generally neutral assessment of the projects and overall progress, and a generally positive assessment with regard to the principal investigators meeting their stated research objectives and performing the planned laboratory research and limited field work. Only one project, the Electrocoagulation Treatability Test, received a rating of 'discontinue' from the team because the project goals had not been met. Because this particular project has already ended, no action with respect to funding withdrawal is necessary. All other projects were recommended to be finished and/or incorporated into field efforts at Hanford. Specific technical comments and recommendations were provided by the team for each project.« less

The evolution of withdrawal: negotiating research relationships in biobanking.

PubMed

Melham, Karen; Moraia, Linda Briceno; Mitchell, Colin; Morrison, Michael; Teare, Harriet; Kaye, Jane

2014-01-01

The right to withdraw from research, along with the necessity of adequately informed consent, is at the heart of the post-Nuremburg code of ethical safeguards in biomedical research on human participants. As biomedical research moves away from direct interventional studies towards research using networks of linked human tissue samples and data, however, questions arise about what withdrawal can and should mean in these new contexts. Some of the more expansive traditional understandings, such as the right to withdraw from a study 'at any time' are limited in practice by the nature of biobank- supported research, particularly where it makes possible widespread dissemination and ongoing reuse of data. It is time for a more nuanced, granular arrangement for withdrawal, appropriate to the ongoing relationships between participants and long-term biobanking enterprises.

Ongoing Voluntary Settlement and Independent Agency: Evidence from China

Voluntary frontier settlement leads to independent agency. Since this type of research has not yet been implemented in ongoing voluntary settlement frontiers, we conducted several cultural tasks to investigate Shenzhen, known as China’s ongoing “South Frontier,” which is composed mostly of people that have emigrated from other Chinese provinces within the past 30 years. We hypothesized that residents of Shenzhen are more independent than those in other regions of Mainland China. As predicted, residents of Shenzhen scored higher than China inland residents in self-reported independent beliefs and scored lower in nepotism. The results indicate that, even in a short-term ongoing frontier, voluntary settlement is associated with independent agency. PMID:28798712

The Interrelationship between Research Integrity, Conflict of Interest, and the Research Environment

PubMed Central

Grinnell, Frederick

2014-01-01

Quite distinct regulatory measures have been established to try to deal with research misconduct and conflict of interest. To decrease research misconduct, the emphasis has been on education aimed at promoting an understanding of and commitment to research integrity. To decrease the impact of conflict of interest, the emphasis has been on management of the research environment. In this essay I discuss the idea that research misconduct and its close relative “questionable research practices” should be framed in the context of conflict of interest. If we take seriously the implication of conflict of interest regulations that even a $5,000 financial interest might bias the design, conduct, or reporting of research, then how much more risk of bias will be in play when what is at stake is ongoing funding of short-term research grants on which a researcher’s salary and job depend? Education is important and necessary to promote research integrity but by itself will not be sufficient. Placing problems of research misconduct and questionable research practices in the context of conflict of interest makes it clear that we also will need to develop new approaches to manage the structure of the research environment. One example of such a management strategy would be for NIH to phase in a limit on the overall percentage of a faculty member’s salary permitted to be supported with NIH grant funds, complementing the already existing upper dollar limit that can be used for faculty salaries.

Framework for Processing Citizens Science Data for Applications to NASA Earth Science Missions

NASA Technical Reports Server (NTRS)

Teng, William; Albayrak, Arif

2017-01-01

Citizen science (or crowdsourcing) has drawn much high-level recent and ongoing interest and support. It is poised to be applied, beyond the by-now fairly familiar use of, e.g., Twitter for natural hazards monitoring, to science research, such as augmenting the validation of NASA earth science mission data. This interest and support is seen in the 2014 National Plan for Civil Earth Observations, the 2015 White House forum on citizen science and crowdsourcing, the ongoing Senate Bill 2013 (Crowdsourcing and Citizen Science Act of 2015), the recent (August 2016) Open Geospatial Consortium (OGC) call for public participation in its newly-established Citizen Science Domain Working Group, and NASA's initiation of a new Citizen Science for Earth Systems Program (along with its first citizen science-focused solicitation for proposals). Over the past several years, we have been exploring the feasibility of extracting from the Twitter data stream useful information for application to NASA precipitation research, with both "passive" and "active" participation by the twitterers. The Twitter database, which recently passed its tenth anniversary, is potentially a rich source of real-time and historical global information for science applications. The time-varying set of "precipitation" tweets can be thought of as an organic network of rain gauges, potentially providing a widespread view of precipitation occurrence. The validation of satellite precipitation estimates is challenging, because many regions lack data or access to data, especially outside of the U.S. and in remote and developing areas. Mining the Twitter stream could augment these validation programs and, potentially, help tune existing algorithms. Our ongoing work, though exploratory, has resulted in key components for processing and managing tweets, including the capabilities to filter the Twitter stream in real time, to extract location information, to filter for exact phrases, and to plot tweet distributions. The key step is to process the "precipitation" tweets to be compatible with satellite-retrieved precipitation data. These key components for processing and managing "precipitation" tweets (and additional ones to be developed) are not limited to precipitation, nor are they limited to the Twitter social medium. Indeed, to maximize the value of our work for NASA earth science programs, these components should be generalized and be part of an overall framework for processing citizen science data for science research. In this paper, we outline such a framework.

A New U.S. Carbon Cycle Science Plan

The report "A U.S. carbon cycle science plan" (J. L. Sarmiento and S. C. Wofsy, U.S. Global Change Res. Program, Washington, D. C., 1999) outlined research priorities and promoted coordinated carbon cycle research across federal agencies in the United States for nearly a decade. Building on this framework and subsequent reports (http://www.carboncyclescience.gov/docs.php), a working group comprised of 27 scientists was formed in 2008 under the United States Carbon Cycle Science Program to review the 1999 Science Plan, and to develop an updated strategy for carbon cycle research for the period from 2010 to 2020. This comprehensive review is being conducted with wide input from the research and stakeholder communities. The recommendations of the Carbon Cycle Science Working Group (CCSWG) will go to U.S. agency managers who have collective responsibility for setting national carbon cycle science priorities and for sponsoring much of the carbon cycle research in the United States. This presentation will provide an update on the ongoing planning process, will outline the steps that the CCSWG is undertaking in building consensus towards an updated U.S. Carbon Cycle Science Plan, and will seek input on the best ways in which to coordinate efforts with ongoing and upcoming research in Canada and Mexico, as well as with ongoing work globally.

Institutional ethical review and ethnographic research involving injection drug users: a case study.

PubMed

Small, Will; Maher, Lisa; Kerr, Thomas

2014-03-01

Ethnographic research among people who inject drugs (PWID) involves complex ethical issues. While ethical review frameworks have been critiqued by social scientists, there is a lack of social science research examining institutional ethical review processes, particularly in relation to ethnographic work. This case study describes the institutional ethical review of an ethnographic research project using observational fieldwork and in-depth interviews to examine injection drug use. The review process and the salient concerns of the review committee are recounted, and the investigators' responses to the committee's concerns and requests are described to illustrate how key issues were resolved. The review committee expressed concerns regarding researcher safety when conducting fieldwork, and the investigators were asked to liaise with the police regarding the proposed research. An ongoing dialogue with the institutional review committee regarding researcher safety and autonomy from police involvement, as well as formal consultation with a local drug user group and solicitation of opinions from external experts, helped to resolve these issues. This case study suggests that ethical review processes can be particularly challenging for ethnographic projects focused on illegal behaviours, and that while some challenges could be mediated by modifying existing ethical review procedures, there is a need for legislation that provides legal protection of research data and participant confidentiality.

Two Antarctic projects developed by solid earth scientists in the GPS and seismology communities have rich education and outreach activities focused on disseminating information gleaned from this research and on including students from underrepresented groups. Members of the UNAVCO and IRIS research consortia along with international partners from Australia, Canada, Chile, Germany, Italy, New Zealand and the U.K. aim to deploy an ambitious GPS/seismic network to observe the Antarctic glaciological and geologic system using a multidisciplinary and internationally coordinated approach. The second project supports this network. UNAVCO and IRIS are designing and building a reliable power and communication system for autonomous polar station operation which use the latest power and communication technologies for ease of deployment and reliable multi-year operation in severe polar environments. This project will disseminate research results through an IPY/POLENET web-based museum style display based on the next-generation "Museum Lite" capability primarily supported by IRIS. "Museum Lite" uses a standard PC, touch-screen monitor, and standard Internet browsers to exploit the scalability and access of the Internet and to provide customizable content in an interactive setting. The unit is suitable for research departments, public schools, and an assortment of public venues, and can provide wide access to real-time geophysical data, ongoing research, and general information. The POLENET group will work with members of the two consortia to provide content about the project and polar science in general. One unit is to be installed at Barrow's Ilisagvit College through the Barrow Arctic Science Consortium, one at McMurdo Station in Antarctica, and two at other sites to be determined (likely in New Zealand/Australia and in the U.S.). In January, 2006, Museum Lite exhibit was installed at the Amundsen-Scott South Pole Station. Evaluation of this prototype is underway. These projects also have a special focus on engaging underrepresented groups in polar science through coalitions with existing recruitment networks and strong, currently operating programs such as the joint UNAVCO-IRIS-USGS program called Research Experiences in Solid Earth Science for Students (RESESS) that provides multi-year research experiences, ongoing mentorship, and a learning community. Undergraduate students will participate in polar research or in development of the new polar equipment.

This article discusses the identification, selection, and refinement of topics for comparative effectiveness systematic reviews within the Agency for Healthcare Research and Quality's Effective Health Care (EHC) program. The EHC program seeks to align its research topic selection with the overall goals of the program, impartially and consistently apply predefined criteria to potential topics, involve stakeholders to identify high-priority topics, be transparent and accountable, and continually evaluate and improve processes. A topic prioritization group representing stakeholder and scientific perspectives evaluates topic nominations that fit within the EHC program (are "appropriate") to determine how "important" topics are as considered against seven criteria. The group then judges whether a new comparative effectiveness systematic review would be a duplication of existing research syntheses, and if not duplicative, if there is adequate type and volume of research to conduct a new systematic review. Finally, the group considers the "potential value and impact" of a comparative effectiveness systematic review. As the EHC program develops, ongoing challenges include ensuring the program addresses truly unmet needs for synthesized research because national and international efforts in this arena are uncoordinated, as well as engaging a range of stakeholders in program decisions while also achieving efficiency and timeliness.

The Environmental Research Letters focus issue on ‘Cumulative Emissions, Global Carbon Budgets and the Implications for Climate Mitigation Targets’ was launched in 2015 to highlight the emerging science of the climate response to cumulative emissions, and how this can inform efforts to decrease emissions fast enough to avoid dangerous climate impacts. The 22 research articles published represent a fantastic snapshot of the state-or-the-art in this field, covering both the science and policy aspects of cumulative emissions and carbon budget research. In this Review and Synthesis, we summarize the findings published in this focus issue, outline some suggestions for ongoing research needs, and present our assessment of the implications of this research for ongoing efforts to meet the goals of the Paris climate agreement.

2011-05-01

The Expanded Owens Valley Solar Array (EOVSA) is now under construction near Big Pine, CA as a solar-dedicated microwave imaging array operating in the frequency range 1-18 GHz. The solar science to be addressed focuses on the 3D structure of the solar corona (magnetic field, temperature and density), on the sudden release of energy and subsequent particle acceleration, transport and heating, and on space weather phenomena. The project will support the scientific community by providing open data access and software tools for analysis of the data, to exploit synergies with on-going solar research in other wavelengths. The New Jersey Institute of Technology (NJIT) is expanding OVSA from its previous complement of 7 antennas to a total of 15 by adding 8 new antennas, and will reinvest in the existing infrastructure by replacing the existing control systems, signal transmission, and signal processing with modern, far more capable and reliable systems based on new technology developed for the Frequency Agile Solar Radiotelescope (FASR). The project will be completed in time to provide solar-dedicated observations during the upcoming solar maximum in 2013 and beyond. We provide an update on current status and our preparations for exploiting the data through modeling and data analysis tools. This research is supported by NSF grants AST-0908344, and AGS-0961867 and NASA grant NNX10AF27G to New Jersey Institute of Technology.

2008-01-01

Health behavior intervention studies have focused primarily on comparing new programs and existing programs via randomized controlled trials. However, numbers of possible components (factors) are increasing dramatically as a result of developments in science and technology (e.g., Web-based surveys). These changes dictate the need for alternative methods that can screen and quickly identify a large set of potentially important treatment components. We have developed and implemented a multiphase experimentation strategy for accomplishing this goal. We describe the screening phase of this strategy and the use of fractional factorial designs (FFDs) in studying several components economically. We then use 2 ongoing behavioral intervention projects to illustrate the usefulness of FFDs. FFDs should be supplemented with follow-up experiments in the refining phase so any critical assumptions about interactions can be verified. PMID:18556602

Occupational health surveillance: a means to identify work-related risks.

PubMed

Froines, J R; Dellenbaugh, C A; Wegman, D H

1986-09-01

The lack of successful disease surveillance methods has resulted in few reliable estimates of workplace-related disease. Hazard surveillance--the ongoing assessment of chemical use and worker exposure to the chemicals--is presented as a way to supplement occupational disease surveillance. Existing OSHA (Occupational Safety and Health Administration) and NIOSH (National Institute for Occupational Health) data systems are adapted to this function to characterize the distribution and type of hazardous industry in Los Angeles County. A new method is developed for ranking potentially hazardous industries in the county using actual exposure measurements from federal OSHA compliance inspections. The strengths of the different systems are presented along with considerations of industrial employment and types of specific chemical exposures. Applications for information from hazard surveillance are discussed in terms of intervention, monitoring exposure control, planning, research, and as a complement to disease surveillance.

A survey of laser lightning rod techniques

Barnes, Arnold A., Jr.; Berthel, Robert O.

1991-01-01

The work done to create a laser lightning rod (LLR) is discussed. Some ongoing research which has the potential for achieving an operational laser lightning rod for use in the protection of missile launch sites, launch vehicles, and other property is discussed. Because of the ease with which a laser beam can be steered into any cloud overhead, an LLR could be used to ascertain if there exists enough charge in the clouds to discharge to the ground as triggered lightning. This leads to the possibility of using LLRs to test clouds prior to launching missiles through the clouds or prior to flying aircraft through the clouds. LLRs could also be used to probe and discharge clouds before or during any hazardous ground operations. Thus, an operational LLR may be able to both detect such sub-critical electrical fields and effectively neutralize them.

Ongoing concerns over the rising cost of health care are driving large-scale changes in the way that health care is practiced and reimbursed in the United States. To effectively implement and thrive within this new health care delivery environment, academic medical institutions will need to modify financial and business models and adapt institutional cultures. In this paper, we review the expected features of the new health care environment from the perspective of academic radiology departments. Our review will include background on Accountable Care Organizations, identify challenges associated with the new managed care model, and outline key strategies—including expanding the use of existing information technology infrastructure, promoting continued medical innovation, balancing academic research with clinical care, and exploring new roles for radiologists in efficient patient management—that will ensure continued success for academic radiology.

Toward an understanding of global change: Initial priorities for US contributions to the International Geosphere-Biosphere Program

NASA Technical Reports Server (NTRS)

1988-01-01

A limited number of high-priority research initiatives are recommended for early implementation as part of the U.S. contribution to the preparatory phase of the International Geosphere-Biosphere Program. The recommendations are based on the committee's analysis of the most critical gaps in the scientific knowledge needed to understand the changes that are occurring in the earth system not being addressed by existing programs. The report articulates a number of important key issues and interactions that characterize global change in the geosphere-biosphere system on time scales of decades to centuries; identifies the knowledge that is the most urgently needed to improve understanding of those issues and interactions; and formulates initial priorities for initial U.S. contributions to the IGBP, recognizing the contributions of other ongoing and proposed programs.

Supercooled and glassy water: Metastable liquid(s), amorphous solid(s), and a no-man’s land

PubMed Central

Handle, Philip H.; Sciortino, Francesco

2017-01-01

We review the recent research on supercooled and glassy water, focusing on the possible origins of its complex behavior. We stress the central role played by the strong directionality of the water–water interaction and by the competition between local energy, local entropy, and local density. In this context we discuss the phenomenon of polyamorphism (i.e., the existence of more than one disordered solid state), emphasizing both the role of the preparation protocols and the transformation between the different disordered ices. Finally, we present the ongoing debate on the possibility of linking polyamorphism with a liquid–liquid transition that could take place in the no-man’s land, the temperature–pressure window in which homogeneous nucleation prevents the investigation of water in its metastable liquid form.

In an ongoing Swedish project studying economic crime in the areas of construction, engineering, and the music industry, 128 informants were interviewed regarding the personal character of the economic criminal compared to that of the law-abiding businessperson. Data were collected from five different regions in Sweden using the Big Five model, the personality model most often used within the field of personality research today. This article compares the results from the interviews with the few international studies that exist regarding economic crimes in these areas and common results are emphasized. It also presents nuanced analyses of the significance of personality in economic crime.

The number of internationally educated nurses is increasing in the Canadian workforce. Recruitment of internationally educated nurses is often seen as a solution to ongoing nursing shortages. However, international recruitment needs to be accompanied by strategies to ensure long-term retention. One of the criteria for successful retention is the availability and accessibility of career advancement and educational opportunities. Little research exists on the opportunities for career advancement and education for internationally educated nurses in Canada. This interpretive descriptive study was conducted to look at the perceptions of internationally educated nurses regarding career advancement and educational opportunities in Alberta, Canada. Eleven internationally educated nurses, working as registered nurses in Alberta, were interviewed using semi-structured interviews. Five themes were identified: motherhood as a priority, communication and cultural challenges, process of skill recognition, perceptions of opportunity and need for mentorship.

LITERATURE FORENSICS? DOOR TO WHAT WAS KNOWN ...

EPA Pesticide Factsheets

Science's all-consuming drive to make new discoveries often risks losing sight of what was already known at one time - that which already exists in the published literature. Inadequate attention to the published literature and insufficient time devoted to its mining and synthesis into new knowledge is a problem faced by all disciplines, especially highly interdisciplinary fields such as environmental forensics, whose knowledge base is fragmented across numerous disciplines. While the conduct of science applies principles of quality assurance to a wide array of its processes, how pervasive are quality controls designed to ensure that planned or ongoing research has not been undertaken before? Has sufficient energy been devoted to mining what has already been discovered and synthesizing it into a larger, more useful perspective? This paper touches on the liabilities associated with insufficient examination of an exponentially growing published literature (

Behavioral Health and Performance at NASA JSC: Recent Successes and Future Plan for BHP Research and Operations

NASA Technical Reports Server (NTRS)

Leveton, L. B.; VanderArk, S. T.

2014-01-01

The Behavioral Health and Performance discipline at NASA Johnson Space Center is organized into two distinct Divisions (Biomedical Research and Environmental Science Division and Space and Clinical Operations Division) but is integrated and interrelated in its day-to-day work. Ongoing operations supporting NASA's spaceflight goals benefit from the research portfolios that address risks to mission success. Similarly, these research portfolios are informed by operations to ensure investigations stay relevant given the dynamic environment of spaceflight. There are many success stories that can be presented where initial work begun as a BHP Research project, and funded through the Human Research Program, was fully implemented in operations or addressed an operational need. Examples include improving effectiveness of the debriefings used within Mission Control by the Mission Operations Directorate and countermeasures for fatigue management. There is also ongoing collaboration with research and operations for developing selection methods for future generation astronauts, and to enhance and inform the current family support function. The objective of this panel is to provide examples of recent success stories, describe areas where close collaboration is benefitting ongoing research and operations, and summarize how this will come together as NASA plans for the one year ISS mission - a unique opportunity for both BHP operations and research to learn more about preparing and supporting crewmembers for extended missions in space. The proposed panel will be comprised of six presentations, each describing a unique aspect of research or operations and the benefits to current and future spaceflight.

Takahashi, Fumiaki; Linteris, Gregory T.; Katta, Viswanath R.

2003-01-01

Longer duration missions to the moon, to Mars, and on the International Space Station (ISS) increase the likelihood of accidental fires. NASA's fire safety program for human-crewed space flight is based largely on removing ignition sources and controlling the flammability of the material on-board. There is ongoing research to improve the flammability characterization of materials in low gravity; however, very little research has been conducted on fire suppression in the low-gravity environment. Although the existing suppression systems aboard the Space Shuttle (halon 1301, CF3Br) and the ISS (CO2 or water-based form) may continue to be used, alternative effective agents or techniques are desirable for long-duration missions. The goal of the present investigation is to: (1) understand the physical and chemical processes of fire suppression in various gravity and O2 levels simulating spacecraft, Mars, and moon missions; (2) provide rigorous testing of analytical models, which include detailed combustion-suppression chemistry and radiation sub-models, so that the model can be used to interpret (and predict) the suppression behavior in low gravity; and (3) provide basic research results useful for advances in space fire safety technology, including new fire-extinguishing agents and approaches.

Supporting Interactive Teaching Methods at the New Faculty Workshop with Astronomy Lecture-Tutorials

NASA Astrophysics Data System (ADS)

Slater, T. F.; Brissenden, G.; Duestua, S.; Prather, E. E.

2004-05-01

Ongoing research by the Conceptual Astronomy and Physics Education Research (CAPER) Team at the University of Arizona Steward Observatory suggests that, although faculty realize that lecture-based instruction is ineffective for many students, they are not aware of what interactive teaching strategies are available, particularly for large enrollment courses. A major emphasis of the AAPT/AAS New Faculty Workshop was to introduce faculty to effective active-learning strategies based on an understanding of how people learn. Faculty were introduced to think-pair-share methods where students work together to explain difficult concepts to each other. Faculty were also introduced to authentic assessment strategies that go beyond using traditional multiple-choice tests. In particular, faculty were introduced to Lecture-Tutorials for Introductory Astronomy. The Lecture-Tutorials are instructional materials intended for use with collaborative student learning groups and are designed specifically to be easily integrated into existing courses centered on conventional lectures and do not require any outside equipment or a drastic course revision for implementation. The materials are based on research into student beliefs and reasoning difficulties and use effective instructional strategies that center on student learning. Each workshop presentation was complimented by a follow-up small group discussion session.

Story-Making as Methodology: Disrupting Dominant Stories through Multimedia Storytelling.

PubMed

Rice, Carla; Mündel, Ingrid

2018-05-01

In this essay, we discuss multimedia story-making methodologies developed through Re•Vision: The Centre for Art and Social Justice that investigates the power of the arts, especially story, to positively influence decision makers in diverse sectors. Our story-making methodology brings together majority and minoritized creators to represent previously unattended experiences (e.g., around mind-body differences, queer sexuality, urban Indigenous identity, and Inuit cultural voice) with an aim to building understanding and shifting policies/practices that create barriers to social inclusion and justice. We analyze our ongoing efforts to rework our storytelling methodology, spotlighting acts of revising carried out by facilitators and researchers as they/we redefine methodological terms for each storytelling context, by researcher-storytellers as they/we rework material from our lives, and by receivers of the stories as we revise our assumptions about particular embodied histories and how they are defined within dominant cultural narratives and institutional structures. This methodology, we argue, contributes to the existing qualitative lexicon by providing innovative new approaches not only for chronicling marginalized/misrepresented experiences and critically researching selves, but also for scaffolding intersectional alliances and for imagining more just futures. © 2018 Canadian Sociological Association/La Société canadienne de sociologie.

Critical operations capabilities in a high cost environment: a multiple case study

NASA Astrophysics Data System (ADS)

Sansone, C.; Hilletofth, P.; Eriksson, D.

2018-04-01

Operations capabilities have been a popular research area for many years and several frameworks have been proposed in the literature. The current frameworks do not take specific contexts into consideration, for instance a high cost environment. This research gap is of particular interest since a manufacturing relocation process has been ongoing the last decades, leading to a huge amount of manufacturing being moved from high to low cost environments. The purpose of this study is to identify critical operations capabilities in a high cost environment. The two research questions were: What are the critical operations capabilities dimensions in a high cost environment? What are the critical operations capabilities in a high cost environment? A multiple case study was conducted and three Swedish manufacturing firms were selected. The study was based on the investigation of an existing framework of operations capabilities. The main dimensions of operations capabilities included in the framework were: cost, quality, delivery, flexibility, service, innovation and environment. Each of the dimensions included two or more operations capabilities. The findings confirmed the validity of the framework and its usefulness in a high cost environment and a new operations capability was revealed (employee flexibility).

The approval of multiple checkpoint inhibitors (CPIs) for the treatment of advanced malignancies has sparked an explosion of research in the field of cancer immunotherapy. Despite the success of these medications, a large number of patients with advanced malignancy do not benefit from therapy. Early research indicates that a therapeutic combination of cancer vaccines with checkpoint inhibitors may lead to synergistic effects and higher response rates than monotherapy. Areas covered: This paper summarizes the previously completed and ongoing research on this exciting combination, including the use of the tumor lysate, particle-loaded dendritic cell (TLPLDC) vaccine combined with checkpoint inhibitors in advanced melanoma. Expert commentary: Increasing experience with CPIs has led to improved understanding of which patients may benefit and it is increasingly clear that the presence of a pre-existing immune response to the tumor, along with tumor-infiltrating lymphocytes, is key to the success of CPIs. One exciting possibility for the future is the addition of a cancer vaccine to CPI therapy, eliciting these crucial T cells, which can then be augmented and protected by the CPI. A number of current and future studies are addressing this very exciting combination therapy.

1993-01-01

A third report from the Atmospheric Effects of Stratospheric Aircraft (AESA) component of NASA's High-Speed Research Program (HSRP) is presented. Market and technology considerations continue to provide an impetus for high-speed civil transport research. A recent United Nations Environment Program scientific assessment showed that considerable uncertainty still exists about the possible impact of aircraft on the atmosphere. The AESA was designed to develop the body of scientific knowledge necessary for the evaluation of the impact of stratospheric aircraft on the atmosphere. The first Program report presented the basic objectives and plans for AESA. This third report marks the midpoint of the program and presents the status of the ongoing research on the impact of stratospheric aircraft on the atmosphere as reported at the third annual AESA Program meeting in June 1993. The focus of the program is on predicted atmospheric changes resulting from projected HSCT emissions. Topics reported on cover how high-speed civil transports (HSCT) might affect stratospheric ozone, emissions scenarios and databases to assess potential atmospheric effects from HSCT's, calculated results from 2-D zonal mean models using emissions data, engine trace constituent measurements, and exhaust plume/aircraft wake vortex interactions.

Thermal Protection Materials Branch (TPMB) has been involved in various research programs to improve the properties and structural integrity of the existing aerospace high temperature materials. Specimens from various research programs were brought into the analytical laboratory for the purpose of obtaining and refining the material characterization. The analytical laboratory in TPMB has many different instruments which were utilized to determine the physical and chemical characteristics of materials. Some of the instruments that were utilized by the SJSU students are: Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDX), X-ray Diffraction Spectrometer (XRD), Fourier Transform-Infrared Spectroscopy (FTIR), Ultra Violet Spectroscopy/Visible Spectroscopy (UV/VIS), Particle Size Analyzer (PSA), and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). The above mentioned analytical instruments were utilized in the material characterization process of the specimens from research programs such as: aerogel ceramics (I) and (II), X-33 Blankets, ARC-Jet specimens, QUICFIX specimens and gas permeability of lightweight ceramic ablators. In addition to analytical instruments in the analytical laboratory at TPMB, there are several on-going experiments. One particular experiment allows the measurement of permeability of ceramic ablators. From these measurements, physical characteristics of the ceramic ablators can be derived.

The increased use of human biological material for cell-based research and clinical interventions poses risks to the privacy of patients and donors, including the possibility of re-identification of individuals from anonymized cell lines and associated genetic data. These risks will increase as technologies and databases used for re-identification become affordable and more sophisticated. Policies that require ongoing linkage of cell lines to donors' clinical information for research and regulatory purposes, and existing practices that limit research participants' ability to control what is done with their genetic data, amplify the privacy concerns. To date, the privacy issues associated with cell-based research and interventions have not received much attention in the academic and policymaking contexts. This paper, arising out of a multi-disciplinary workshop, aims to rectify this by outlining the issues, proposing novel governance strategies and policy recommendations, and identifying areas where further evidence is required to make sound policy decisions. The authors of this paper take the position that existing rules and norms can be reasonably extended to address privacy risks in this context without compromising emerging developments in the research environment, and that exceptions from such rules should be justified using a case-by-case approach. In developing new policies, the broader framework of regulations governing cell-based research and related areas must be taken into account, as well as the views of impacted groups, including scientists, research participants and the general public. This paper outlines deliberations at a policy development workshop focusing on privacy challenges associated with cell-based research and interventions. The paper provides an overview of these challenges, followed by a discussion of key themes and recommendations that emerged from discussions at the workshop. The paper concludes that privacy risks associated with cell-based research and interventions should be addressed through evidence-based policy reforms that account for both well-established legal and ethical norms and current knowledge about actual or anticipated harms. The authors also call for research studies that identify and address gaps in understanding of privacy risks.

2015-12-02

The increasing emphasis on research, development and innovation for health in providing solutions to the high burden of diseases in the African Region has warranted a proliferation of studies including clinical trials. This changing public health landscape requires that countries develop adequate ethics review capacities to protect and minimize risks to study participants. Therefore, this study assessed the readiness of national ethics committees to respond to challenges posed by a globalized biomedical research system which is constantly challenged by new public health threats, rapid scientific and technological advancements affecting biomedical research and development, delivery and manufacture of vaccines and therapies, and health technology transfer. This is a descriptive study, which used a questionnaire structured to elicit information on the existence of relevant national legal frameworks, mechanisms for ethical review; as well as capacity requirements for national ethics committees. The questionnaire was available in English and French and was sent to 41 of the then 46 Member States of the WHO African Region, excluding the five Lusophone Member States. Information was gathered from senior officials in ministries of health, who by virtue of their offices were considered to have expert knowledge of research ethics review systems in their respective countries. Thirty three of the 41 countries (80.5 %) responded. Thirty (90.9 %) of respondent countries had a national ethics review committee (NEC); 79 % of which were established by law. Twenty-five (83.3 %) NECs had secretarial and administrative support. Over 50 % of countries with NECs indicated a need for capacity strengthening through periodic training on international guidelines for health research (including clinical trials) ethics; and allocation of funds for administrative and secretariat support. Despite the existing training initiatives, the Region still experiences a shortage of professionals trained in health research ethics/ethicists. Committees continue to face various capacity needs especially for evaluating clinical trials, for monitoring ongoing research, database management and for accrediting institutional ethics committees. Given the growing number of clinical trials involving human participants in the African Region, there is urgent need for supporting countries without NECs to establish them; capacity strengthening where they exist; and creation of a regional network and joint ethical review mechanisms, whose membership would be open to all NECs of the Region.

Ongoing developments in RSV prophylaxis: a clinician's analysis.

PubMed

Rezaee, Fariba; Linfield, Debra T; Harford, Terri J; Piedimonte, Giovanni

2017-06-01

Respiratory syncytial virus (RSV) is the most common respiratory pathogen in infants and young children worldwide. Lower respiratory tract infection due to RSV is one of the most common causes of hospitalization for infants, especially those born premature or with chronic lung or heart disease. Furthermore, RSV infection is an important cause of morbidity in adults, particularly in the elderly and immunocompromised individuals. The acute phase of this infection is often followed by episodes of wheezing that recur for months or years and usually lead to a physician diagnosis of asthma. RSV was discovered more than 50 years ago, and despite extensive research to identify pharmacological therapies, the most effective management of this infection remains supportive care. The trial of a formalin-inactivated RSV vaccine in the 1960s resulted in priming the severe illness upon natural infection. Currently, Palivizumab is the only available option for RSV prophylaxis, and because of restricted clinical benefits and high costs, it has been limited to a group of high-risk infants. There are several ongoing trials in preclinical, Phase-I, Phase-II, or Phase-III clinical stages for RSV vaccine development based on various strategies. Here we review the existing available prophylactic options, the current stages of RSV vaccine clinical trials, different strategies, and major hurdles in the development of an effective RSV vaccine.

This technical report responds to the recognition by the U.S. Global Change Research Program (USGCRP) and the National Climate Assessment (NCA) of the importance of understanding how land use and land cover (LULC) affects weather and climate variability and change and how that variability and change affects LULC. Current published, peer-reviewed, scientific literature and supporting data from both existing and original sources forms the basis for this report's assessment of the current state of knowledge regarding land change and climate interactions. The synthesis presented herein documents how current and future land change may alter environment processes and in turn, how those conditions may affect both land cover and land use by specifically investigating, * The primary contemporary trends in land use and land cover, * The land-use and land-cover sectors and regions which are most affected by weather and climate variability,* How land-use practices are adapting to climate change, * How land-use and land-cover patterns and conditions are affecting weather and climate, and * The key elements of an ongoing Land Resources assessment. These findings present information that can be used to better assess land change and climate interactions in order to better assess land management and adaptation strategies for future environmental change and to assist in the development of a framework for an ongoing national assessment.

Pulmonary fibrosis and exposure to steel welding fume.

Cosgrove, M P

2015-12-01

Arc welders who have been exposed to high concentrations of steel welding fume for prolonged periods of time may develop pulmonary fibrosis but the nature of the fibrotic changes has been debated over the last 80 years without any clear international consensus. To characterize the nature of the pulmonary fibrosis that develops in response to steel welding fume exposure and to provide a working hypothesis that would explain the findings of the existing research, to provide a platform for future research and to inform future occupational and clinical management of welders with pulmonary effects from welding fume. Review of the world literature on pulmonary fibrosis and welding of steel in all languages using PubMed, with further secondary search of references in the articles found in the primary search. Google and Reference Manager were used as further confirmatory search tools. Only case series and case reports were found but these provided consistent evidence that the consequence of exposure to steel welding fume at high levels for a prolonged period of time is a type of pulmonary fibrosis similar to, and possibly the same as, respiratory bronchiolitis which eventually develops into desquamative interstitial pneumonia with ongoing exposure. Steel welding fume may cause an occupational respiratory bronchiolitis which may develop into de squamative interstitial pneumonia with ongoing exposure. This concept may explain the difficulties in interpreting the wider literature on welding fume and lung function at lower exposures and may also explain the increased risk of lung cancer in welders. © The Author 2015.

2.1 Natural History of Highly Pathogenic Avian Influenza H5N1

PubMed Central

Sonnberg, Stephanie; Webby, Richard J.; Webster, Robert G.

2013-01-01

The ecology of highly pathogenic avian influenza (HPAI) H5N1 has significantly changed from sporadic outbreaks in terrestrial poultry to persistent circulation in terrestrial and aquatic poultry and potentially in wild waterfowl. A novel genotype of HPAI H5N1 arose in 1996 in southern China and through ongoing mutation, reassortment, and natural selection, has diverged into distinct lineages and expanded into multiple reservoir hosts. The evolution of Goose/Guangdong-lineage highly pathogenic H5N1 viruses is ongoing: while stable interactions exist with some reservoir hosts, these viruses are continuing to evolve and adapt to others, and pose an un-calculable risk to sporadic hosts, including humans.

Visually Evoked Spiking Evolves While Spontaneous Ongoing Dynamics Persist

Huys, Raoul; Jirsa, Viktor K.; Darokhan, Ziauddin; Valentiniene, Sonata; Roland, Per E.

2016-01-01

Neurons in the primary visual cortex spontaneously spike even when there are no visual stimuli. It is unknown whether the spiking evoked by visual stimuli is just a modification of the spontaneous ongoing cortical spiking dynamics or whether the spontaneous spiking state disappears and is replaced by evoked spiking. This study of laminar recordings of spontaneous spiking and visually evoked spiking of neurons in the ferret primary visual cortex shows that the spiking dynamics does not change: the spontaneous spiking as well as evoked spiking is controlled by a stable and persisting fixed point attractor. Its existence guarantees that evoked spiking return to the spontaneous state. However, the spontaneous ongoing spiking state and the visual evoked spiking states are qualitatively different and are separated by a threshold (separatrix). The functional advantage of this organization is that it avoids the need for a system reorganization following visual stimulation, and impedes the transition of spontaneous spiking to evoked spiking and the propagation of spontaneous spiking from layer 4 to layers 2–3.

The process by which climate models are evaluated has evolved substantially over the past decade, with the Coupled Model Intercomparison Project (CMIP) serving as a centralizing activity for coordinating model experimentation and enabling research. Scientists with a broad spectrum of expertise have contributed to the CMIP model evaluation process, resulting in many hundreds of publications that have served as a key resource for the IPCC process. For several reasons, efforts are now underway to further systematize some aspects of the model evaluation process. First, some model evaluation can now be considered routine and should not require "re-inventing the wheel" or a journal publication simply to update results with newer models. Second, the benefit of CMIP research to model development has not been optimal because the publication of results generally takes several years and is usually not reproducible for benchmarking newer model versions. And third, there are now hundreds of model versions and many thousands of simulations, but there is no community-based mechanism for routinely monitoring model performance changes. An important change in the design of CMIP6 can help address these limitations. CMIP6 will include a small set standardized experiments as an ongoing exercise (CMIP "DECK": ongoing Diagnostic, Evaluation and Characterization of Klima), so that modeling groups can submit them at any time and not be overly constrained by deadlines. In this presentation, efforts to establish routine benchmarking of existing and future CMIP simulations will be described. To date, some benchmarking tools have been made available to all CMIP modeling groups to enable them to readily compare with CMIP5 simulations during the model development process. A natural extension of this effort is to make results from all CMIP simulations widely available, including the results from newer models as soon as the simulations become available for research. Making the results from routine performance tests readily accessible will help advance a more transparent model evaluation process.

Photovoltaics: Energy for the New Millenium

NASA Astrophysics Data System (ADS)

Surek, Thomas

2000-04-01

Photovoltaics (PV) is a semiconductor-based technology that directly converts sunlight to electricity. The stimulus for terrestrial PV started more than 25 years ago in response to the oil crises of the 1970s, which resulted in major government programs in the United States, Europe, Japan, and elsewhere. Ongoing concerns with the global environment, as well as the worldwide efforts to seek alternate, indigenous sources of energy, continue to drive the investment in PV research and deployment. Today, the manufacture, sale, and use of PV has become a billion-dollar industry worldwide, with nearly 200 megawatts (MW) of PV modules shipped in 1999. The twenty five years of research and development led to the discovery of new PV materials, devices, and fabrication approaches; continuing improvements in the efficiency and reliability of solar cells and modules; and lower PV module and system costs. This talk reviews the rapid progress that has occurred in PV technology from the laboratory to the marketplace, including reviews of the leading technology options, status and issues, and key industry players. New processes for fabricating PV materials and devices, and innovative PV approaches with low-cost potential are elements of an ongoing research program aimed at future advancements in PV cost and performance While major market opportunities continue to exist in the developing countries, where sizable populations are without any electricity, today's manufacturing expansions are fueled by market initiatives for grid-connected PV in residential and commercial buildings. The combinations of increased production capacities, with the attendant cost reductions as a result of economies of scale, are expected to lead to sustainable markets. A key to achieving the ultimate potential of PV is to continue to increase the sunlight-to-electricity conversion efficiencies and translate the laboratory successes to cost-competitive products. Building a robust technology base is essential to overcoming this high-risk transition. Then PV will make a globally significant contribution to our energy supply and environment.

Knight-Jones, T J D; Robinson, L; Charleston, B; Rodriguez, L L; Gay, C G; Sumption, K J; Vosloo, W

2016-06-01

This study assessed knowledge gaps in foot-and-mouth disease (FMD) research in the field of diagnostics. The study took the form of a literature review (2011-15) combined with research updates collected in 2014 from 33 institutes from around the world. Findings were used to identify priority areas for future FMD research. Molecular and genetic technologies, including sequencing, are developing at an increasing rate both in terms of capability and affordability. These advances potentiate progress in many other fields of research, from vaccine development to epidemiology. The development of RT-LAMP represents an important breakthrough allowing greater use and access to molecular diagnostics. It is now possible to determine virus serotype using PCR, although only for certain virus pools, continued progress is needed to cover the global spectrum of FMD viruses. Progress has also been made in the development of pen-side rapid diagnostics, some with the ability to determine serotype. However, further advances in pen-side serotype or strain determination would benefit both FMD-free countries and endemic countries with limited access to well-resourced laboratories. Novel sampling methods that show promise include air sampling and baited ropes, the latter may aid sampling in wildlife and swine. Studies of infrared thermography for the early detection of FMD have not been encouraging, although investigations are ongoing. Multiplex tests have been developed that are able to simultaneously screen for multiple pathogens with similar clinical signs. Crucial for assessing FMDV freedom, tests exist to detect animals that have been infected with FMDV regardless of vaccination status; however, limitations exist, particularly when testing previously vaccinated animals. Novel vaccines are being developed with complementary DIVA tests for this purpose. Research is also needed to improve the current imprecise approaches to FMD vaccine matching. The development of simple, affordable tests increases access to FMD diagnostics, greatly benefiting regions with limited laboratory capacity. © 2016 Blackwell Verlag GmbH.

Health care professionals' views of the factors influencing the decision to refer patients to a stroke rehabilitation trial.

Effective recruitment is an essential element of successful research but notoriously difficult to achieve. This article examines health care professionals' views on the factors influencing decision-making regarding referral to a stroke rehabilitation trial. Semi-structured interviews and a card-sorting task were undertaken with stroke service staff in acute and community hospital trusts. Data analysis used a thematic framework approach. Twenty-seven qualified health care professionals from 12 (6 acute and 6 community) hospital trusts and one charity participated. Four main factors emerged: patient-related, professional views, the organisation and research logistics, which all contributed to staff's decision about whether to refer patients to a trial. Clinicians identified patient-related factors as the most frequent influence and considered themselves the patients' advocate. They used their knowledge of the patient to anticipate the patients' reaction to possible participation and tended to only refer those whom they perceived would respond positively. Participants also identified experience of research, a sense of ownership of the project and a positive view of the intervention being evaluated as factors influencing referral. The need to prioritise clinical matters, meet managerial demands and cope with constant change were organisational factors impacting negatively on referral. Staff often simply forgot about recruitment in the face of other higher priorities. Quick, simple, flexible research processes that were closely aligned with existing ways of working were felt to facilitate recruitment. Patient- and professional-related factors were the most frequent influence on clinicians' recruitment decisions, which often had a 'gate-keeping' effect. Managerial and clinical responsibility to juggle multiple (often higher) priorities was also an important factor. To facilitate recruitment, researchers need to develop strategies to approach potential participants as directly as possible to enable them to make their own decisions about participation; ensure that research processes are as quick and simple as possible; align with existing clinical pathways and systems; and give regular reminders and ongoing support to promote recruitment.

Druckenmiller, M. L.; Perovich, D. K.; Francis, J. A.

2017-12-01

Arctic sea ice supports and intersects a multitude of societal benefit areas, including regulating regional and global climates, structuring marine food webs, providing for traditional food provisioning by indigenous peoples, and constraining marine shipping and access. At the same time, sea ice is one of the most rapidly changing elements of the Arctic environment and serves as a source of key physical indicators for monitoring Arctic change. Before the present scientific interest in Arctic sea ice for climate research, it has long been, and remains, a focus of applied research for industry and national security. For generations, the icy coastal seas of the North have also provided a basis for the sharing of local and indigenous knowledge between Arctic residents and researchers, including anthropologists, biologists, and geoscientists. This presentation will summarize an ongoing review of existing synthesis studies of Arctic sea ice. We will chart efforts to achieve system-level understanding across geography, temporal scales, and the ecosystem services that Arctic sea ice supports. In doing so, we aim to illuminate the role of interdisciplinary science, together with local and indigenous experts, in advancing knowledge of the roles of sea ice in the Arctic system and beyond, reveal the historical and scientific evolution of sea-ice research, and assess current gaps in system-scale understanding.

A striking disparity exists across the globe, with essentially no large-scale longitudinal studies ongoing in regions that will be significantly affected by the oncoming non-communicable disease epidemic. The successful implementation of cohort studies in most low-resource research environments presents unique challenges that may be aided by coordinated training programs. Leaders of emerging cohort studies attending the First World Cohort Integration Workshop were surveyed about training priorities, unmet needs and potential cross-cohort solutions to these barriers through an electronic pre-workshop questionnaire and focus groups. Cohort studies representing India, Mexico, Nigeria, South Africa, Sweden, Tanzania and Uganda described similar training needs, including on-the-job training, data analysis software instruction, and database and bio-bank management. A lack of funding and protected time for training activities were commonly identified constraints. Proposed solutions include a collaborative cross-cohort teaching platform with web-based content and interactive teaching methods for a range of research personnel. An international network for research mentorship and idea exchange, and modifying the graduate thesis structure were also identified as key initiatives. Cross-cohort integrated educational initiatives will efficiently meet shared needs, catalyze the development of emerging cohorts, speed closure of the global disparity in cohort research, and may fortify scientific capacity development in low-resource settings.

Levy-Storms, Lené

2008-10-01

The purpose of this review is to critique contemporary experimental research and to recommend future directions for research interventions on nursing aides' therapeutic communication with older adults who have cognitive impairment and/or dementia in institutional long-term care settings. This literature review covers 13 journal articles (1999-2006) and focuses on the strengths and weaknesses of experimental research interventions to improve nursing aides' therapeutic communication with older adults who have cognitive impairment and/or dementia in long-term care settings. Based on this review, recommendations for improved experimental designs include a minimum of two groups with one being a control and randomization of subjects at the care unit level, an average 3-5h of total training, a minimum of a 6-month total evaluation period, and objective outcomes relevant to both nursing aides and residents. Findings from studies in this review indicate that the following therapeutic communication techniques can be taught and can benefit staffs and older adults' quality of life: verbal and non-verbal communication behaviors including open-ended questions, positive statements, eye contact, affective touch, and smiling. Some evidence exists to support that nursing aides can improve their therapeutic communication during care. Nursing aides need not only more training in therapeutic communication but also ongoing, dedicated supervision in psychosocial aspects of care.

Adapting an existing visualization application for browser-based deployment: A case study from the Tropical Rainfall Measuring Mission

NASA Astrophysics Data System (ADS)

Kelley, Owen A.

2013-02-01

THOR, the Tool for High-resolution Observation Review, is a data viewer for the Tropical Rainfall Measuring Mission (TRMM) and the upcoming Global Precipitation Measurement (GPM) mission. THOR began as a desktop application, but now it can be accessed with a web browser, making THOR one of the first online tools for visualizing TRMM satellite data (http://pps.gsfc.nasa.gov/thor). In this effort, the reuse of the existing visualization code was maximized and the complexity of new code was minimized by avoiding unnecessary functionality, frameworks, or libraries. The simplicity of this approach makes it potentially attractive to researchers wishing to adapt their visualization applications for online deployment. To enable THOR to run within a web browser, three new pieces of code are written. First, the graphical user interface (GUI) of the desktop application is translated into HTML, JavaScript, and CSS. Second, a simple communication mechanism is developed over HTTP. Third, a virtual GUI is created on the server that interfaces with the image-generating routines of the existing desktop application so that these routines do not need to be modified for online use. While the basic functionality of THOR is now available online, prototyping is ongoing for enhanced 3D imaging and other aspects of both THOR Desktop and THOR Online. Because TRMM data products are complex and periodically reprocessed with improved algorithms, having a tool such as THOR is important to analysts at the Precipitation Processing System where the algorithms are tested and the products generated, stored, and distributed. Researchers also have found THOR useful for taking a first look at individual files before writing their own software to perform specialized calculations and analyses.

This paper introduces a new cooperative research program of national scale that is focused on crucial research issues in the development of high energy microwave sources. These have many applications in the DOD and industry. The Air Force Office of Scientific Research (AFOSR), in cooperation with the Phillips Laboratory, the Naval Research Laboratory, and the Army Research Laboratory, has established a tri-service research consortium to investigate novel high energy microwave sources. To facilitate the rapid transition of research results into the industrial community, formal collaborative subcontracts are already in-place with James Benford at Physics International, Carter Armstrong at Northrop, andmore » Glen Huffman at Varian Associates. Although this new program officially only came into existence in mid-March of this year, it builds on over a decade of microwave research efforts funded by the plasma physics office at AFOSR. It also is synergistic with the ongoing Tri-Service Vacuum Electronics Initiative led by Robert Parker of NRL as well as with the AFOSR`s and Rome Laboratory`s long-standing Advanced Thermionic Research Initiative (ATRI). An overview will be given of the broad spectrum of research objectives encompassed by NUCOMR. Areas of collaboration and technology transfer will be highlighted. The areas in which the three university consortia will conduct research are described, and the connectivity to industry and to the DOD laboratories are discussed. There are a number of critical technical barriers to reaching the desired goals for high power and high energy sources. These are discussed and the planned focus of research to resolve them is also presented.« less

Advanced Scintillator Detectors for Neutron Imaging in Inertial Confinement Fusion

NASA Astrophysics Data System (ADS)

Geppert-Kleinrath, Verena; Danly, Christopher; Merrill, Frank; Simpson, Raspberry; Volegov, Petr; Wilde, Carl

2016-10-01

The neutron imaging team at Los Alamos National Laboratory (LANL) has been providing two-dimensional neutron imaging of the inertial confinement fusion process at the National Ignition Facility (NIF) for over five years. Neutron imaging is a powerful tool in which position-sensitive detectors register neutrons emitted in the fusion reactions, producing a picture of the burning fuel. Recent images have revealed possible multi-dimensional asymmetries, calling for additional views to facilitate three-dimensional imaging. These will be along shorter lines of sight to stay within the existing facility at NIF. In order to field imaging capabilities equivalent to the existing system several technological challenges have to be met: high spatial resolution, high light output, and fast scintillator response to capture lower-energy neutrons, which have scattered from non-burning regions of fuel. Deuterated scintillators are a promising candidate to achieve the timing and resolution required; a systematic study of deuterated and non-deuterated polystyrene and liquid samples is currently ongoing. A test stand has been implemented to measure the response function, and preliminary data on resolution and light output have been obtained at the LANL Weapons Neutrons Research facility.

Agentic women and communal leadership: how role prescriptions confer advantage to top women leaders.

PubMed

Rosette, Ashleigh Shelby; Tost, Leigh Plunkett

2010-03-01

The authors contribute to the ongoing debate about the existence of a female leadership advantage by specifying contextual factors that moderate the likelihood of the emergence of such an advantage. The investigation considered whether the perceived role incongruence between the female gender role and the leader role led to a female leader disadvantage (as predicted by role congruity theory) or whether instead a female leader advantage would emerge (as predicted by double standards and stereotype content research). In Study 1, it was only when success was internally attributed that women top leaders were evaluated as more agentic and more communal than men top leaders. Study 2 showed that the favorable ratings were unique to top-level positions and further showed that the effect on agentic traits was mediated by perceptions of double standards, while the effect on communal traits was mediated by expectations of feminized management skills. Finally, Study 2 showed that top women leaders were evaluated most favorably on overall leader effectiveness, and this effect was mediated by both mediators. Our results support the existence of a qualified female leadership advantage. 2010 APA, all rights reserved

Ceramic Composite Development for Gas Turbine Engine Hot Section Components

NASA Technical Reports Server (NTRS)

DiCarlo, James A.; VANrOODE, mARK

2006-01-01

The development of ceramic materials for incorporation into the hot section of gas turbine engines has been ongoing for about fifty years. Researchers have designed, developed, and tested ceramic gas turbine components in rigs and engines for automotive, aero-propulsion, industrial, and utility power applications. Today, primarily because of materials limitations and/or economic factors, major challenges still remain for the implementation of ceramic components in gas turbines. For example, because of low fracture toughness, monolithic ceramics continue to suffer from the risk of failure due to unknown extrinsic damage events during engine service. On the other hand, ceramic matrix composites (CMC) with their ability to display much higher damage tolerance appear to be the materials of choice for current and future engine components. The objective of this paper is to briefly review the design and property status of CMC materials for implementation within the combustor and turbine sections for gas turbine engine applications. It is shown that although CMC systems have advanced significantly in thermo-structural performance within recent years, certain challenges still exist in terms of producibility, design, and affordability for commercial CMC turbine components. Nevertheless, there exist some recent successful efforts for prototype CMC components within different engine types.

Universality of the logarithmic velocity profile restored

NASA Astrophysics Data System (ADS)

Luchini, Paolo

2017-11-01

The logarithmic velocity profile of wall-bounded turbulent flow, despite its widespread adoption in research and in teaching, exhibits discrepancies with both experiments and numerical simulations that have been repeatedly observed in the literature; serious doubts ensued about its precise form and universality, leading to the formulation of alternate theories and hindering ongoing experimental efforts to measure von Kármán's constant. By comparing different geometries of pipe, plane-channel and plane-Couette flow, here we show that such discrepancies can be physically interpreted, and analytically accounted for, through an equally universal higher-order correction caused by the pressure gradient. Inclusion of this term produces a tenfold increase in the adherence of the predicted profile to existing experiments and numerical simulations in all three geometries. Universality of the logarithmic law then emerges beyond doubt and a satisfactorily simple formulation is established. Among the consequences of this formulation is a strongly increased confidence that the Reynolds number of present-day direct numerical simulations is actually high enough to uncover asymptotic behaviour, but research efforts are still needed in order to increase their accuracy.

The University of Michigan's Michigan Institute for Clinical & Health Research and Fast Forward Medical Innovation (FFMI) partnered to develop a pilot program designed to teach CTSA hubs how to implement innovation and entrepreneurship programs at their home institutions. The program provided a 2-day onsite training experience combined with observation of an ongoing course focused on providing biomedical innovation, commercialization and entrepreneurial training to a medical academician audience (FFMI fast PACE). All 9 participating CTSA institutes reported a greater connection to biomedical research commercialization resources. Six launched their own version of the FFMI fast PACE course or modified existing programs. Two reported greater collaboration with their technology transfer offices. The FFMI fast PACE course and training program may be suitable for CTSA hubs looking to enhance innovation and entrepreneurship within their institutions and across their innovation ecosystems.

Peer support is a promising model of providing psychosocial support to parents of children with type 1 diabetes. This review seeks to discuss the findings of the existing literature in peer coaching as it relates to parents and diabetes as well as to identify gaps in knowledge for future intervention development and implementation. Peer support programs vary widely with regard to recruitment, training, and delivery protocols. Across most programs, ongoing support and supervision are provided to peer coaches. Despite inconsistent effects on psychosocial and child health outcomes, parent coaching is consistently a highly acceptable and feasible intervention with parents of children with T1D. Current evidence supports use of parent coaching as part of a multicomponent intervention or program to increase patient satisfaction, but more research is needed to determine if it can stand alone as an active mechanism for behavior change. The use of peer coach interventions for parents of young children with diabetes is feasible to implement and highly acceptable. However, more research is needed to understand the enduring impact for target parents and peer coaches alike, as well as impact on child outcomes.

This project represents a no-cost agreement between National Aeronautic Space Administration Goddard Space Flight Center (NASA GSFC) and the Pacific Northwest Laboratory (PNL). PNL is a Department of Energy (DOE) national laboratory operted by Battelle Memorial Institute at its Pacific Northwest Laboratories in Richland, Washington. The objective of this investigation is to evaluate LANDSAT's thematic mapper (TM) data quality and utility characteristics from an energy research and technological perspective. Of main interest is the extent to which repetitive TM data might support DOE efforts relating to siting, developing, and monitoring energy-related facilities, and to basic geoscientific research. The investigation utilizes existing staff and facility capabilities, and ongoing programmatic activities at PNL and other DOE national laboratories to cooperatively assess the potential usefulness of the improved experimental TM data. The investigation involves: (1) both LANDSAT 4 and 5 TM data, (2) qualitative and quantitative use consideration, and 3) NASA P (corrected) and A (uncorrected) CCT analysis for a variety of sites of DOE interest. Initial results were presented at the LANDSAT Investigator's Workshops and at specialized LANDSAT TM sessions at various conferences.

The Association of Physical Activity and Academic Behavior: A Systematic Review.

PubMed

Sullivan, Rachel A; Kuzel, AnnMarie H; Vaandering, Michael E; Chen, Weiyun

2017-05-01

In this systematic review, we assessed the existing research describing the effects of physical activity (PA) on academic behavior, with a special focus on the effectiveness of the treatments applied, study designs, outcome measures, and results. We obtained data from various journal search engines and 218 journal articles were downloaded that were relevant to PA and academic performance topics. The abstracts of all the articles were independently peer reviewed to assess whether they met the inclusion criteria for further analysis. The literature search was ongoing. Of the reviewed articles, 9 were chosen on the topic of PA effects on academic behavior. Each article was analyzed and summarized using a standard summary template. Overall, PA interventions commonly found positive effects on academic behavior, with few exceptions. There were additional unique findings regarding differences in outcome measures and PA treatments. The findings from these studies are significant and support the implementation or continuation of PA in schools to improve academic behavior and associated performance. More research needs to be conducted using the effective aspects of the treatments from this review with consistent outcome measures. © 2017, American School Health Association.

Building Power Between Polarities: On the Space-in-Between.

PubMed

Ventres, William B

2016-02-01

In this article, I introduce the concept of the space-in-between. This space-in-between is born of the realization that, between the expression of any two polarities (across dimensions such as emotion, thought, geography, and ideology), there exists a philosophical construct useful for framing thinking about practice, research, and managerial relationships in the health professions. Out of this construct emerge practical considerations useful for structuring the conduct of meaningful interpersonal and intercultural interactions. I describe how the idea of a space-in-between developed out of my medical practice, grew as a result of my experiences in international environments. and has found fulfillment in my ongoing work. I explore the application of a space-in-between in public health, medical anthropology, medical ethics, and global health. I review how, as a result of incorporating this space in their daily work, clinicians, educators, researchers, and managers can grow as leaders by sharing the presence that arises from the space-in-between them and the people in the communities they serve. © The Author(s) 2015.

Distribution of valuable research discoveries are needed for the continual advancement of patient care. Publication and subsequent reliance of false study results would be detrimental for patient care. Unfortunately, research misconduct may originate from many sources. While there is evidence of ongoing research misconduct in all it's forms, it is challenging to identify the actual occurrence of research misconduct, which is especially true for misconduct in clinical trials. Research misconduct is challenging to measure and there are few studies reporting the prevalence or underlying causes of research misconduct among biomedical researchers. Reported prevalence estimates of misconduct are probably underestimates, and range from 0.3% to 4.9%. There have been efforts to measure the prevalence of research misconduct; however, the relatively few published studies are not freely comparable because of varying characterizations of research misconduct and the methods used for data collection. There are some signs which may point to an increased possibility of research misconduct, however there is a need for continued self-policing by biomedical researchers. There are existing resources to assist in ensuring appropriate statistical methods and preventing other types of research fraud. These included the "Statistical Analyses and Methods in the Published Literature", also known as the SAMPL guidelines, which help scientists determine the appropriate method of reporting various statistical methods; the "Strengthening Analytical Thinking for Observational Studies", or the STRATOS, which emphases on execution and interpretation of results; and the Committee on Publication Ethics (COPE), which was created in 1997 to deliver guidance about publication ethics. COPE has a sequence of views and strategies grounded in the values of honesty and accuracy.

Bartsch, Hauke; Thompson, Wesley K.; Jernigan, Terry L.; Dale, Anders M.

2014-01-01

Clinical research studies generate data that need to be shared and statistically analyzed by their participating institutions. The distributed nature of research and the different domains involved present major challenges to data sharing, exploration, and visualization. The Data Portal infrastructure was developed to support ongoing research in the areas of neurocognition, imaging, and genetics. Researchers benefit from the integration of data sources across domains, the explicit representation of knowledge from domain experts, and user interfaces providing convenient access to project specific data resources and algorithms. The system provides an interactive approach to statistical analysis, data mining, and hypothesis testing over the lifetime of a study and fulfills a mandate of public sharing by integrating data sharing into a system built for active data exploration. The web-based platform removes barriers for research and supports the ongoing exploration of data. PMID:24723882

The Ethical, Legal, and Social Implications Program of the National Human Genome Research Institute: reflections on an ongoing experiment.

PubMed

McEwen, Jean E; Boyer, Joy T; Sun, Kathie Y; Rothenberg, Karen H; Lockhart, Nicole C; Guyer, Mark S

2014-01-01

For more than 20 years, the Ethical, Legal, and Social Implications (ELSI) Program of the National Human Genome Research Institute has supported empirical and conceptual research to anticipate and address the ethical, legal, and social implications of genomics. As a component of the agency that funds much of the underlying science, the program has always been an experiment. The ever-expanding number of issues the program addresses and the relatively low level of commitment on the part of other funding agencies to support such research make setting priorities especially challenging. Program-supported studies have had a significant impact on the conduct of genomics research, the implementation of genomic medicine, and broader public policies. The program's influence is likely to grow as ELSI research, genomics research, and policy development activities become increasingly integrated. Achieving the benefits of increased integration while preserving the autonomy, objectivity, and intellectual independence of ELSI investigators presents ongoing challenges and new opportunities.

Elite control of HIV: is this the right model for a functional cure?

PubMed

Cockerham, Leslie R; Hatano, Hiroyu

2015-02-01

A cure for HIV is still greatly needed and has become a global research priority. A unique subset of HIV-infected individuals who spontaneously control HIV exists, and these are known as 'elite controllers'. They may represent a natural model for a 'functional cure' in which there is long term control of viral replication and remission from symptoms of HIV infection in the absence of antiretroviral therapy. However, controllers have evidence of ongoing inflammation, CD4(+) T cell depletion, and perhaps even inflammation-associated cardiovascular disease, suggesting that this natural long term virologic control may be coming at an immunologic and clinical cost. These individuals may continue to provide continued insights into mechanisms of host control; however, they may not represent the best model of a functional cure, if we believe that a cure should require a disease-free (and not just a treatment-free) state.

How community action, science and common sense can work together to develop an alternative way to combat desertification.

PubMed

Bethune, Shirley; Schachtschneider, Klaudia

2004-12-01

The Spitzkoppe Community Campsite in western Namibia lies in an area with very limited water resources. Water scarcity places a constraint on community income generation and development opportunities. The existing water resources are overexploited and to ensure future water security, the community must take sustainable water management into consideration in their daily lives and business ventures, including tourism. This has been successfully achieved at the Spitzkoppe Community Campsite through a combination of high community motivation, organisation and action, the involvement of researchers and trainers in water resource management and support from developers. The most appropriate water management solutions were found through ongoing practical testing of different strategies and technologies over two years. This paper presents a case study of a community-based tourist camp at Spitzkoppe and traces the community's progress towards developing an alternative way to combat desertification and a potentially lucrative tourist business.

On the viability of supporting institutional sharing of remote laboratory facilities

NASA Astrophysics Data System (ADS)

Lowe, David; Dang, Bridgette; Daniel, Keith; Murray, Stephen; Lindsay, Euan

2015-11-01

Laboratories are generally regarded as critical to engineering education, and yet educational institutions face significant challenges in developing and maintaining high-quality laboratory facilities. Remote laboratories are increasingly being explored as a partial solution to this challenge, with research showing that - for the right learning outcomes - they can be viable adjuncts or alternatives to conventional hands-on laboratories. One consequential opportunity arising from the inherent support for distributed access is the possibility of cross-institutional shared facilities. While both technical feasibility and pedagogic implications of remote laboratories have been well studied within the literature, the organisational and logistical issues associated with shared facilities have received limited consideration. This paper uses an existing national-scale laboratory sharing initiative, along with a related survey and laboratory sharing data, to analyse a range of factors that can affect engagement in laboratory sharing. The paper also discusses the implications for supporting ongoing laboratory sharing.

Physics Teaching in Times of Change

NASA Astrophysics Data System (ADS)

Dykstra, Dewey

2006-05-01

Powerful political forces have been at play in building a mandate to change the schools. The latest, on-going manifestation is in the No Child Left Behind Act, but the mandate for change was being formulated in the early 1980s in the A Nation at Risk report. As physicists we may feel somewhat removed from such goings on, but our children attend school and their teachers come through our classrooms. Physics education research offers extensive, carefully collected data on the consequences of standard physics teaching. The data challenges conventional beliefs about physics learning. It is said that times of crisis represent both opportunity and danger. Because the mandates to change are up to the individual states, each of us in our own state has the opportunity to shift the focus in physics/science teaching toward something better. We also face the danger that existing physics/science teaching will be even more deeply entrenched than it already is.

Modeling the potential radionuclide transport by the Ob and Yenisey Rivers to the Kara Sea.

Paluszkiewicz, T; Hibler, L F; Richmond, M C; Bradley, D J; Thomas, S A

2001-01-01

A major portion of the former Soviet Union (FSU) nuclear program is located in the West Siberian Basin. Among the many nuclear facilities are three production reactors and the spent nuclear fuel reprocessing sites, Mayak, Tomsk-7, and Krasnoyarsk-26, which together are probably responsible for the majority of the radioactive contamination found in the Ob and Yenisey River systems that feed into the Arctic Ocean through the Kara Sea. This manuscript describes ongoing research to estimate radionuclide fluxes to the Kara Sea from these river systems. Our approach is to apply a hierarchy of simple models that use existing and forthcoming data to quantify the transport and fate of radionuclide contaminants via various environmental pathways. We present an initial quantification of the contaminant inventory, hydrology, meteorology, and sedimentology of the Ob River system and preliminary conclusions from portions of the Ob River model.

Our land, our language: connecting dispossession and health equity in an indigenous context.

2012-06-01

For contemporary Indigenous people, colonial relations (past and present) intersect with neoliberal policies and practices to create subtle forms of dispossession.These undermine the health of Indigenous peoples and create barriers restricting access to appropriate health services. Integrating insights from the critical geographer David Harvey, the authors demonstrate how the dispossession of land and language threaten health and well-being and worsen existing illness conditions. Drawing on the qualitative findings from a program of community-based research with the 'Namgis First Nation in the Canadian province of British Columbia, the authors argue for an account of how neoliberal mechanisms operate to further the "accumulation by dispossession" associated with historical and ongoing colonialism. Specifically, they show how neoliberal ideologies operate to sustain medical colonialism and health inequities for Indigenous peoples. The authors discuss the implications for nursing actions to achieve health equity in rural First Nations communities.

Pregnancy-related pelvic girdle pain: an update

PubMed Central

2011-01-01

A large number of scientists from a wide range of medical and surgical disciplines have reported on the existence and characteristics of the clinical syndrome of pelvic girdle pain during or after pregnancy. This syndrome refers to a musculoskeletal type of persistent pain localised at the anterior and/or posterior aspect of the pelvic ring. The pain may radiate across the hip joint and the thigh bones. The symptoms may begin either during the first trimester of pregnancy, at labour or even during the postpartum period. The physiological processes characterising this clinical entity remain obscure. In this review, the definition and epidemiology, as well as a proposed diagnostic algorithm and treatment options, are presented. Ongoing research is desirable to establish clear management strategies that are based on the pathophysiologic mechanisms responsible for the escalation of the syndrome's symptoms to a fraction of the population of pregnant women.

The development of a multi-target compiler-writing system for flight software development

NASA Technical Reports Server (NTRS)

Feyock, S.; Donegan, M. K.

1977-01-01

A wide variety of systems designed to assist the user in the task of writing compilers has been developed. A survey of these systems reveals that none is entirely appropriate to the purposes of the MUST project, which involves the compilation of one or at most a small set of higher-order languages to a wide variety of target machines offering little or no software support. This requirement dictates that any compiler writing system employed must provide maximal support in the areas of semantics specification and code generation, the areas in which existing compiler writing systems as well as theoretical underpinnings are weakest. This paper describes an ongoing research and development effort to create a compiler writing system which will overcome these difficulties, thus providing a software system which makes possible the fast, trouble-free creation of reliable compilers for a wide variety of target computers.

A method of producing high quality oxide and related films on surfaces

NASA Technical Reports Server (NTRS)

Ruckman, Mark W.; Strongin, Myron; Gao, Yongli

1991-01-01

Aluminum oxide or aluminum nitride films were deposited on molecular beam epitaxy (MBE) grown GaAS(100) using a novel cryogenic-based reactive thin film deposition technique. The process involves the condensation of molecular oxygen, ammonia, or other gases normally used for reactive thin film deposition on the substrate before the metal is deposited. The metal vapor is deposited into this layer and reacts with the molecular solid to form the desired compound or a precursor that can be thermally decomposed to generate the desired compound. The films produced by this method are free of impurities, and the low temperatures can be used to control the film and interfacial structure. The process can be easily integrated with existing MBE systems. Ongoing research using the same apparatus suggests that photon or electron irradiation could be used to promote the reactions needed to produce the intended material.

Financial dimensions of veterinary medical education: an economist's perspective.

PubMed

Lloyd, James W

2013-01-01

Much discussion has transpired in recent years related to the rising cost of veterinary medical education and the increasing debt loads of graduating veterinarians. Underlying these trends are fundamental changes in the funding structure of higher education in general and of academic veterinary medicine specifically. As a result of the ongoing disinvestment by state governments in higher education, both tuition rates and academic programs have experienced a substantial impact across US colleges and schools of veterinary medicine. Programmatically, the effects have spanned the entire range of teaching, research, and service activities. For graduates, both across higher education and in veterinary medicine specifically, the impact has been steadily increasing levels of student debt. Although the situation is clearly worrisome, viable repayment options exist for these escalating debt loads. In combination with recent income and employment trends for veterinarians, these options provide a basis for cautious optimism for the future.

Patient decision making among older individuals with cancer.

Strohschein, Fay J; Bergman, Howard; Carnevale, Franco A; Loiselle, Carmen G

2011-07-01

Patient decision making is an area of increasing inquiry. For older individuals experiencing cancer, variations in health and functional status, physiologic aspects of aging, and tension between quality and quantity of life present unique challenges to treatment-related decision making. We used the pragmatic utility method to analyze the concept of patient decision making in the context of older individuals with cancer. We first evaluated its maturity in existing literature and then posed analytical questions to clarify aspects found to be only partially mature. In this context, we found patient decision making to be an ongoing process, changing with time, reflecting individual and relational components, as well as analytical and emotional ones. Assumptions frequently associated with patient decision making were not consistent with the empirical literature. Careful attention to the multifaceted components of patient decision making among older individuals with cancer provides guidance for research, supportive interventions, and targeted follow-up care.

The aim was to explore the process of involving mental healthcare service users in a mental health promotion research project as research advisors and to articulate features of the collaboration which encouraged and empowered the advisors to make significant contributions to the research process and outcome. There is an increasing interest in evaluating aspects of service user involvement in nursing research. Few descriptions exist of features that enable meaningful service user involvement. We draw on experiences from conducting research which used the methodology interpretative phenomenological analysis to explore how persons with mental disorders perceived mental health. Aside from the participants in the project, five research advisors with service user experience were involved in the entire research process. We applied a case study design to explore the ongoing processes of service user involvement. Documents and texts produced while conducting the project (2012-2016), as well as transcripts from multistage focus group discussions with the research advisors, were analysed. The level of involvement was dynamic and varied throughout the different stages of the research process. Six features: leadership, meeting structure, role clarification, being members of a team, a focus on possibilities and being seen and treated as holistic individuals, were guiding principles for a salutogenic service user involvement. These features strengthened the advisors' perception of themselves as valuable and competent contributors. Significant contributions from research advisors were promoted by facilitating the process of involvement. A supporting structure and atmosphere were consistent with a salutogenic service user involvement. This article is protected by copyright. All rights reserved. This article is protected by copyright.

The US Air Force Office of Scientific Research convened a meeting of researchers in the fields of neuroscience, psychology, engineering, and medicine to discuss most pressing issues facing ongoing research in the field of transcranial direct current stimulation (tDCS) and related techniques. In this study, we present opinions prepared by participants of the meeting, focusing on the most promising areas of research, immediate and future goals for the field, and the potential for hormesis theory to inform tDCS research. Scientific, medical, and ethical considerations support the ongoing testing of tDCS in healthy and clinical populations, provided best protocols are used to maximize safety. Notwithstanding the need for ongoing research, promising applications include enhancing vigilance/attention in healthy volunteers, which can accelerate training and support learning. Commonly, tDCS is used as an adjunct to training/rehabilitation tasks with the goal of leftward shift in the learning/treatment effect curves. Although trials are encouraging, elucidating the basic mechanisms of tDCS will accelerate validation and adoption. To this end, biomarkers (eg, clinical neuroimaging and findings from animal models) can support hypotheses linking neurobiological mechanisms and behavioral effects. Dosage can be optimized using computational models of current flow and understanding dose–response. Both biomarkers and dosimetry should guide individualized interventions with the goal of reducing variability. Insights from other applied energy domains, including ionizing radiation, transcranial magnetic stimulation, and low-level laser (light) therapy, can be prudently leveraged. PMID:28210202

The common data elements (CDE) project was developed by the National Institute of Neurological Disorders and Stroke (NINDS) to provide clinical researchers with tools to improve data quality and allow for harmonization of data collected in different research studies. CDEs have been created for several neurological diseases; the aim of this project was to develop CDEs specifically curated for mitochondrial disease (Mito) to enhance clinical research. Nine working groups (WGs), composed of international mitochondrial disease experts, provided recommendations for Mito clinical research. They initially reviewed existing NINDS CDEs and instruments, and developed new data elements or instruments when needed. Recommendations were organized, internally reviewed by the Mito WGs, and posted online for external public comment for a period of eight weeks. The final version was again reviewed by all WGs and the NINDS CDE team prior to posting for public use. The NINDS Mito CDEs and supporting documents are publicly available on the NINDS CDE website ( https://commondataelements.ninds.nih.gov/ ), organized into domain categories such as Participant/Subject Characteristics, Assessments, and Examinations. We developed a comprehensive set of CDE recommendations, data definitions, case report forms (CRFs), and guidelines for use in Mito clinical research. The widespread use of CDEs is intended to enhance Mito clinical research endeavors, including natural history studies, clinical trial design, and data sharing. Ongoing international collaboration will facilitate regular review, updates and online publication of Mito CDEs, and support improved consistency of data collection and reporting.

Characterizing high-energy-density propellants for space propulsion applications

NASA Astrophysics Data System (ADS)

Kokan, Timothy

There exists wide ranging research interest in high-energy-density matter (HEDM) propellants as a potential replacement for existing industry standard fuels for liquid rocket engines. The U.S. Air Force Research Laboratory, the U.S. Army Research Lab, the NASA Marshall Space Flight Center, and the NASA Glenn Research Center each either recently concluded or currently has ongoing programs in the synthesis and development of these potential new propellants. In order to perform conceptual designs using these new propellants, most conceptual rocket engine powerhead design tools (e.g. NPSS, ROCETS, and REDTOP-2) require several thermophysical properties of a given propellant over a wide range of temperature and pressure. These properties include enthalpy, entropy, density, viscosity, and thermal conductivity. Very little thermophysical property data exists for most of these potential new HEDM propellants. Experimental testing of these properties is both expensive and time consuming and is impractical in a conceptual vehicle design environment. A new technique for determining these thermophysical properties of potential new rocket engine propellants is presented. The technique uses a combination of three different computational methods to determine these properties. Quantum mechanics and molecular dynamics are used to model new propellants at a molecular level in order to calculate density, enthalpy, and entropy. Additivity methods are used to calculate the kinematic viscosity and thermal conductivity of new propellants. This new technique is validated via a series of verification experiments of HEDM compounds. Results are provided for two HEDM propellants: quadricyclane and 2-azido-N,N-dimethylethanamine (DMAZ). In each case, the new technique does a better job than the best current computational methods at accurately matching the experimental data of the HEDM compounds of interest. A case study is provided to help quantify the vehicle level impacts of using HEDM propellants. The case study consists of the National Aeronautics and Space Administration's (NASA) Exploration Systems Architecture Study (ESAS) Lunar Surface Access Module (LSAM). The results of this study show that the use of HEDM propellants instead of hypergolic propellants can lower the gross weight of the LSAM and may be an attractive alternative to the current baseline hypergolic propellant choice.

Consistent detection and identification of individuals in a large camera network

In the wake of an increasing number of terrorist attacks, counter-terrorism measures are now a main focus of many research programmes. An important issue for the police is the ability to track individuals and groups reliably through underground stations, and in the case of post-event analysis, to be able to ascertain whether specific individuals have been at the station previously. While there exist many motion detection and tracking algorithms, the reliable deployment of them in a large network is still ongoing research. Specifically, to track individuals through multiple views, on multiple levels and between levels, consistent detection and labelling of individuals is crucial. In view of these issues, we have developed a change detection algorithm to work reliably in the presence of periodic movements, e.g. escalators and scrolling advertisements, as well as a content-based retrieval technique for identification. The change detection technique automatically extracts periodically varying elements in the scene using Fourier analysis, and constructs a Markov model for the process. Training is performed online, and no manual intervention is required, making this system suitable for deployment in large networks. Experiments on real data shows significant improvement over existing techniques. The content-based retrieval technique uses MPEG-7 descriptors to identify individuals. Given the environment under which the system operates, i.e. at relatively low resolution, this approach is suitable for short timescales. For longer timescales, other forms of identification such as gait, or if the resolution allows, face recognition, will be required.

The Perfect Storm: Preterm Birth, Neurodevelopmental Mechanisms, and Autism Causation.

PubMed

Erdei, Carmina; Dammann, Olaf

2014-01-01

A unifying model of autism causation remains elusive, and thus well-designed explanatory models are needed to develop appropriate therapeutic and preventive interventions. This essay argues that autism is not a static disorder, but rather an ongoing process. We discuss the link between preterm birth and autism and briefly review the evidence supporting the link between immune system characteristics and both prematurity and autism. We then propose a causation process model of autism etiology and pathogenesis, in which both neurodevelopment and ongoing/prolonged neuroinflammation are necessary pathogenetic component mechanisms. We suggest that an existing model of sufficient cause and component causes can be interpreted as a mechanistic view of etiology and pathogenesis and can serve as an explanatory model for autism causal pathways.

A qualitative study exploring the value of a catheter passport.

Many patients leaving hospital with a catheter do not have sufficient information to self-care and can experience physical and psychological difficulties. This study aimed to explore how a patient-held catheter passport affects the experiences of patients leaving hospital with a urethral catheter, the hospital nurses who discharge them and the community nurses who provide ongoing care for them. Qualitative methods used included interviews, focus groups and questionnaires, and thematic analysis. Three major themes were reported-informing patients, informing nurses; improving catheter care, promoting self-management; and supporting transition. The catheter passport can bridge the existing information gap, improve care, promote self-care and help patients adjust to their catheter, especially if complemented by ongoing input from a nurse or other health professional.

2015-01-01

The NASA Langley Aeroelasticity Branch is involved in a number of research programs related to fixed wing aeroelasticity and aeroservoelasticity. These ongoing efforts are summarized here, and include aeroelastic tailoring of subsonic transport wing structures, experimental and numerical assessment of truss-braced wing flutter and limit cycle oscillations, and numerical modeling of high speed civil transport configurations. Efforts devoted to verification, validation, and uncertainty quantification of aeroelastic physics in a workshop setting are also discussed. The feasibility of certain future civil transport configurations will depend on the ability to understand and control complex aeroelastic phenomena, a goal that the Aeroelasticity Branch is well-positioned to contribute through these programs.

Spousal Coping Strategies in the Shadow of Terrorism.

PubMed

Shechory-Bitton, Mally; Cohen-Louck, Keren

2017-11-01

The present study focuses on spousal differences in reaction to ongoing exposure to terror and security threats. Sixty-eight married couples with children living in a region exposed to ongoing security threats were evaluated. All participants completed questionnaires on objective exposure (number of incidents) and subjective exposure (sense of fear) to terrorism and security threats, posttraumatic stress disorder (PTSD) symptoms, and their coping strategies with this ongoing exposure. Mothers reported higher levels of fear and PTSD symptoms, although their objective levels of exposure did not differ from those of their husbands. Similarities were found in coping strategies adopted by mothers and fathers to cope with life in the shadow of terrorism. Both mothers and fathers integrated emotion- and problem-focused coping strategies, with greater use of the latter. These similarities partially contradict research findings suggesting gender differences in coping with exposure to security threats. The results support the need for further research into investigating the role of dyadic coping in the context of prolonged exposure to security threats.

2017-01-01

Evaluation capacity building (ECB) is a topic of great interest to many organizations as they face increasing demands for accountability and evidence-based practices. ECB is about building the knowledge, skills, and attitudes of organizational members, the sustainability of rigorous evaluative practices, and providing the resources and motivations to engage in ongoing evaluative work. There exists a solid foundation of theoretical research on ECB, however, understanding what ECB looks like in practice is relatively thin. Our purpose was to investigate what ECB looks like firsthand within a national medical educational organization. The context for this study was the Acute Critical Events Simulation (ACES) organization in Canada, which has successfully evolved into a national educational program, driven by physicians. We conducted an exploratory qualitative study to better understand and describe ECB in practice. In doing so, interviews were conducted with program leaders and instructors so as to gain a richer understanding of evaluative processes and practices. A total of 21 individuals participated in the semistructured interviews. Themes from our qualitative data analysis included the following: evaluation knowledge, skills, and attitudes, use of evaluation findings, shared evaluation beliefs and commitment, evaluation frameworks and processes, and resources dedicated to evaluation. The national ACES organization was a useful case study to explore ECB in practice. The ECB literature provided a solid foundation to understand the purpose and nuances of ECB. This study added to the paucity of studies focused on examining ECB in practice. The most important lesson learned was that the organization must have leadership who are intrinsically motivated to employ and use evaluation data to drive ongoing improvements within the organization. Leaders who are intrinsically motivated will employ risk taking when evaluation practices and processes may be somewhat unfamiliar. Creating and maintaining a culture of data use and ongoing inquiry have enabled national ACES to achieve a sustainable evaluation practice.

Large-scale implementation of evidence-based psychotherapies (EBPs) such as cognitive processing therapy (CPT) for posttraumatic stress disorder can have a tremendous impact on mental and physical health, healthcare utilization, and quality of life. While many mental health systems (MHS) have invested heavily in programs to implement EBPs, few eligible patients receive EBPs in routine care settings, and clinicians do not appear to deliver the full treatment protocol to many of their patients. Emerging evidence suggests that when CPT and other EBPs are delivered at low levels of fidelity, clinical outcomes are negatively impacted. Thus, identifying strategies to improve and sustain the delivery of CPT and other EBPs is critical. Existing literature has suggested two competing strategies to promote sustainability. One emphasizes fidelity to the treatment protocol through ongoing consultation and fidelity monitoring. The other focuses on improving the fit and effectiveness of these treatments through appropriate adaptations to the treatment or the clinical setting through a process of data-driven, continuous quality improvement. Neither has been evaluated in terms of impact on sustained implementation. To compare these approaches on the key sustainability outcomes and provide initial guidance on sustainability strategies, we propose a cluster randomized trial with mental health clinics (n = 32) in three diverse MHSs that have implemented CPT. Cohorts of clinicians and clinical managers will participate in 1 year of a fidelity oriented learning collaborative or 1 year of a continuous quality improvement-oriented learning collaborative. Patient-level PTSD symptom change, CPT fidelity and adaptation, penetration, and clinics' capacity to deliver EBP will be examined. Survey and interview data will also be collected to investigate multilevel influences on the success of the two learning collaborative strategies. This research will be conducted by a team of investigators with expertise in CPT implementation, mixed method research strategies, quality improvement, and implementation science, with input from stakeholders in each participating MHS. It will have broad implications for supporting ongoing delivery of EBPs in mental health and healthcare systems and settings. The resulting products have the potential to significantly improve efforts to ensure ongoing high quality implementation and consumer access to EBPs. NCT02449421 . Registered 02/09/2015.

The scientific status of childhood dissociative identity disorder: a review of published research.

PubMed

Boysen, Guy A

2011-01-01

Dissociative identity disorder (DID) remains a controversial diagnosis due to conflicting views on its etiology. Some attribute DID to childhood trauma and others attribute it to iatrogenesis. The purpose of this article is to review the published cases of childhood DID in order to evaluate its scientific status, and to answer research questions related to the etiological models. I searched MEDLINE and PsycINFO records for studies published since 1980 on DID/multiple personality disorder in children. For each study I coded information regarding the origin of samples and diagnostic methods. The review produced a total of 255 cases of childhood DID reported as individual case studies (44) or aggregated into empirical studies (211). Nearly all cases (93%) emerged from samples of children in treatment, and multiple personalities was the presenting problem in 23% of the case studies. Four US research groups accounted for 65% of all 255 cases. Diagnostic methods typically included clinical evaluation based on Diagnostic and Statistical Manual of Mental Disorder criteria, but hypnosis, structured interviews, and multiple raters were rarely used in diagnoses. Despite continuing research on the related concepts of trauma and dissociation, childhood DID itself appears to be an extremely rare phenomenon that few researchers have studied in depth. Nearly all of the research that does exist on childhood DID is from the 1980s and 1990s and does not resolve the ongoing controversies surrounding the disorder. Copyright © 2011 S. Karger AG, Basel.

Transitioning a Fundamental Research Program to Align with the NASA Exploration Initiative-Perspectives from Microgravity Combustion Science and Fluid Physics

NASA Technical Reports Server (NTRS)

Sutliff, Thomas J.; Kohl, Fred J.

2004-01-01

A new Vision for Space Exploration was announced earlier this year by U.S. President George W. Bush. NASA has evaluated on-going programs for strategic alignment with this vision. The evaluation proceeded at a rapid pace and is resulting in changes to the scope and focus of experimental research that will be conducted in support of the new vision. The existing network of researchers in the physical sciences - a highly capable, independent, and loosely knitted community - typically have shared conclusions derived from their work within appropriate discipline-specific peer reviewed journals and publications. The initial result of introducing this Vision for Space Exploration has been to shift research focus from a broad coverage of numerous, widely varying topics into a research program focused on a nearly-singular set of supporting research objectives to enable advances in space exploration. Two of these traditional physical science research disciplines, Combustion Science and Fluid Physics, are implementing a course adjustment from a portfolio dominated by "Fundamental Science Research" to one focused nearly exclusively on supporting the Exploration Vision. Underlying scientific and engineering competencies and infrastructure of the Microgravity Combustion Science and Fluid Physics disciplines do provide essential research capabilities to support the contemporary thrusts of human life support, radiation countermeasures, human health, low gravity research for propulsion and materials and, ultimately, research conducted on the Moon and Mars. A perspective on how these two research disciplines responded to the course change will be presented. The relevance to the new NASA direction is provided, while demonstrating through two examples how the prior investment in fundamental research is being brought to bear on solving the issues confronting the successful implementation of the exploration goals.

Reporting trends of spinal cord injury research representation: a media content analysis.

PubMed

Kehn, Matthew; Kroll, Thilo

2011-04-01

Over the past few decades, medical and technological advances in rehabilitation have improved the lives of people with spinal cord injury (SCI). More recently, promises of embryonic stem cell research has made finding a cure for SCI a real possibility, and the media and public have seemingly focused accordingly. Examining media reporting trends of SCI research can help interested researchers, clinicians, and policy makers understand how such research is framed for the public. We sought to identify potential differences in reporting trends between rehabilitation-focused and cure-focused SCI research and to juxtapose those trends with a timeline of other news events. LexisNexis search was performed on 5 U.S. newspapers to identify articles on SCI research between 1998 and 2007. Eligible articles were reviewed and data extracted including type and context of research, referenced institutions, quoted individuals, and other cited news events. The search identified 356 articles on SCI research; 80% were cure focused and mostly referenced in the context of funding or promotion, and 11% were rehabilitation focused and were mostly referenced in the context of ongoing conduction or application of findings. Commonly cited news events included President Bush's 2001 federal funding restriction on embryonic stem cell research and the injury and death of Christopher Reeve. Research focused on curing SCI has received more attention by some print media than research aimed at rehabilitating SCI. The context in which each is referenced differs significantly. Cure-focused research may have benefited from a stronger and more prominent coalition of advocates, its political and controversial nature, and the existence of reporting "triggers."

Five principles for the practice of knowledge exchange in environmental management.

PubMed

Reed, M S; Stringer, L C; Fazey, I; Evely, A C; Kruijsen, J H J

2014-12-15

This paper outlines five principles for effective practice of knowledge exchange, which when applied, have the potential to significantly enhance the impact of environmental management research, policy and practice. The paper is based on an empirical analysis of interviews with 32 researchers and stakeholders across 13 environmental management research projects, each of which included elements of knowledge co-creation and sharing in their design. The projects focused on a range of upland and catchment management issues across the UK, and included Research Council, Government and NGO funded projects. Preliminary findings were discussed with knowledge exchange professionals and academic experts to ensure the emerging principles were as broadly applicable as possible across multiple disciplines. The principles suggest that: knowledge exchange needs to be designed into research; the needs of likely research users and other stakeholders should be systematically represented in the research where possible; and long-term relationships must be built on trust and two-way dialogue between researchers and stakeholders in order to ensure effective co-generation of new knowledge. We found that the delivery of tangible benefits early on in the research process helps to ensure continued motivation and engagement of likely research users. Knowledge exchange is a flexible process that must be monitored, reflected on and continuously refined, and where possible, steps should be taken to ensure a legacy of ongoing knowledge exchange beyond initial research funding. The principles have been used to inform the design of knowledge exchange and stakeholder engagement guidelines for two international research programmes. They are able to assist researchers, decision-makers and other stakeholders working in contrasting environmental management settings to work together to co-produce new knowledge, and more effectively share and apply existing knowledge to manage environmental change.

The gap in the health of the nations' people seems to be widening and reflects existing social inequalities affecting the ongoing health of individuals. From a historical and practical perspective, certified nurse-midwives (CNMs) are one group of advanced practice registered nurses uniquely situated to address existing disparities related to maternal-child health. This article provides an overview of the historical development, current status, and use of CNMs in the United States health care system; the impact of CNMs on maternal-child health outcomes; and future trends in the education of CNMs. Copyright © 2012 Elsevier Inc.

KENNEDY SPACE CENTER, FLA. - The doors on the 39-year-0ld Vehicle Assembly Building are getting a needed face-lift to repair the damage caused by prolonged exposure to the Florida environment - one of the most corrosive in the nation. The North Transfer Aisle and the High Bay 3 Vertical and Horizontal doors have entered a 13-month restoration period. Extensive corrosion damage exists on the interior of the framework of the existing doors in both locations. All exterior siding is to be replaced, as well as all the hardware. The work contributes to the ongoing safety and infrastructure upgrade efforts at Kennedy Space Center.

We describe the development and implementation of a randomized controlled trial to investigate the impact of genomic counseling on a cohort of patients with heart failure (HF) or hypertension (HTN), managed at a large academic medical center, the Ohio State University Wexner Medical Center (OSUWMC). Our study is built upon the existing Coriell Personalized Medicine Collaborative (CPMC®). OSUWMC patient participants with chronic disease (CD) receive eight actionable complex disease and one pharmacogenomic test report through the CPMC® web portal. Participants are randomized to either the in-person post-test genomic counseling—active arm, versus web-based only return of results—control arm. Study-specific surveys measure: (1) change in risk perception; (2) knowledge retention; (3) perceived personal control; (4) health behavior change; and, for the active arm (5), overall satisfaction with genomic counseling. This ongoing partnership has spurred creation of both infrastructure and procedures necessary for the implementation of genomics and genomic counseling in clinical care and clinical research. This included creation of a comprehensive informed consent document and processes for prospective return of actionable results for multiple complex diseases and pharmacogenomics (PGx) through a web portal, and integration of genomic data files and clinical decision support into an EPIC-based electronic medical record. We present this partnership, the infrastructure, genomic counseling approach, and the challenges that arose in the design and conduct of this ongoing trial to inform subsequent collaborative efforts and best genomic counseling practices.

To determine whether recently published and ongoing systematic reviews of therapeutic interventions assess patient-important outcomes. For this methodological review, we searched MEDLINE via PubMed for recently published systematic reviews and online registry of systematic reviews (PROSPERO) for ongoing systematic reviews. We selected systematic reviews with meta-analyses of randomized controlled trials. We extracted all outcomes defined in the methods section and categorized them. Mortality, other clinical events, pain, quality of life, function, and therapeutic decisions were considered patient-important outcomes. We included 420 systematic reviews: 90 Cochrane reviews, 200 other published reviews, and 130 registered ongoing reviews. Primary outcomes were defined in 85 Cochrane reviews (95%), 98 (49%) other published reviews and all ongoing reviews. At least one patient-important outcome was defined as a primary outcome in 81/85 Cochrane reviews (95%), 78/98 other published reviews (80%), and 117/130 ongoing reviews (90%). Considering all outcomes assessed, at least one patient-important outcome was evaluated in 90/90 Cochrane reviews (100%), 189/200 other published reviews (95%), and 121/130 ongoing reviews (93%). Most recent systematic reviews aim to assess patient-important outcomes, which contrasts with RCTs. These results suggest some important gaps between primary and secondary research.

In Australia telephone surveys have been the method of choice for ongoing jurisdictional population health surveys. Although it was estimated in 2011 that nearly 20% of the Australian population were mobile-only phone users, the inclusion of mobile phone numbers into these existing landline population health surveys has not occurred. This paper describes the methods used for the inclusion of mobile phone numbers into an existing ongoing landline random digit dialling (RDD) health survey in an Australian state, the New South Wales Population Health Survey (NSWPHS). This paper also compares the call outcomes, costs and the representativeness of the resultant sample to that of the previous landline sample. After examining several mobile phone pilot studies conducted in Australia and possible sample designs (screening dual-frame and overlapping dual-frame), mobile phone numbers were included into the NSWPHS using an overlapping dual-frame design. Data collection was consistent, where possible, with the previous years' landline RDD phone surveys and between frames. Survey operational data for the frames were compared and combined. Demographic information from the interview data for mobile-only phone users, both, and total were compared to the landline frame using χ2 tests. Demographic information for each frame, landline and the mobile-only (equivalent to a screening dual frame design), and the frames combined (with appropriate overlap adjustment) were compared to the NSW demographic profile from the 2011 census using χ2 tests. In the first quarter of 2012, 3395 interviews were completed with 2171 respondents (63.9%) from the landline frame (17.6% landline only) and 1224 (36.1%) from the mobile frame (25.8% mobile only). Overall combined response, contact and cooperation rates were 33.1%, 65.1% and 72.2% respectively. As expected from previous research, the demographic profile of the mobile-only phone respondents differed most (more that were young, males, Aboriginal and Torres Strait Islanders, overseas born and single) compared to the landline frame responders. The profile of respondents from the two frames combined, with overlap adjustment, was most similar to the latest New South Wales (NSW) population profile. The inclusion of the mobile phone numbers, through an overlapping dual-frame design, did not impact negatively on response rates or data collection, and although costing more the design was still cost-effective because of the additional interviews that were conducted with young people, Aboriginal and Torres Strait Islanders and people who were born overseas resulting in a more representative overall sample.
