With the newspapers' recent move to online reporting, traditional norms and practices of news reporting have changed to accommodate the new realities of online news writing. In particular, online news is much more fluid and prone to change in content than the traditional hard-copy newspapers--online newspaper articles often change over the course of the following days or even weeks as they respond to criticisms and new information becoming available. This poses a problem for social scientists who analyse newspaper coverage of science, health and risk topics, because it is no longer clear who has read and written what version, and what impact they potentially had on the national debates on these topics. In this note I want to briefly flag up this problem through two recent examples of U.K. national science stories and discuss the potential implications for PUS media research.

Objective: In the past decades economic sanctions have been used by different countries or international organizations in order to deprive target countries of some transactions. While the sanctions do not target health care systems or public health structures, they may, in fact, affect the availability of health care in target countries. In this study, we used media analysis to assess the impacts of recent sanctions imposed by the Central Bank of Iran in 2012 on access to medicines in Iran. Methods: We searched different sources of written news media including a database of nonspecialized weeklies and magazines, online news sources, web pages of daily newspapers and healthcare oriented weeklies from 2011 to 2013. We searched the sources using the general term “medicine” to reduce the chances of missing relevant items. The identified news media were read, and categorized under three groups of items announcing “shortage of medicines,” “medicines related issues” and “no shortage.” We conducted trend analyzes to see whether the news media related to access to medicines were affected by the economic sanctions. Findings: A total number of 371 relevant news media were collected. The number of news media related to medicines substantially increased in the study period: 30 (8%), 161 (43%) and 180 (49%) were published in 2011, 2012 and 2013, respectively. While 145 (39%) of media items referred to the shortage of medicines, 97 (26%) reported no shortage or alleviating of concerns. Conclusion: Media analysis suggests a clear increase in the number of news media reporting a shortage in Iran after the sanctions. In 2013, there were accompanying increases in the number of news media reporting alleviation of the shortages of medicines. Our analysis provides evidence of negative effects of the sanctions on access to medicines in Iran. PMID:26645026

Unlike most online social networks where explicit links among individual users are defined, the relations among commercial entities (e.g. firms) may not be explicitly declared in commercial Web sites. One main contribution of this article is the development of a novel computational model for the discovery of the latent relations among commercial entities from online financial news. More specifically, a CRF model which can exploit both structural and contextual features is applied to commercial entity recognition. In addition, a point-wise mutual information (PMI)-based unsupervised learning method is developed for commercial relation identification. To evaluate the effectiveness of the proposed computational methods, a prototype system called CoNet has been developed. Based on the financial news articles crawled from Google finance, the CoNet system achieves average F-scores of 0.681 and 0.754 in commercial entity recognition and commercial relation identification, respectively. Our experimental results confirm that the proposed shallow natural language processing methods are effective for the discovery of latent commercial networks from online financial news.

The Internet is one of the fastest growing news sources for many worldwide (Pew Research Center's Project for Excellence in Journalism, 2011), and cancer news is one frequently consumed form of online health information (Google, Inc., 2007). This content analysis of online cancer news (n = 862) retrieved from the four most frequented news websites describes trends regarding specific cancers, stages in the cancer continuum, and types of news articles. In general, treatment information received the most attention in online cancer news. Breast cancer received the most attention of each specific cancer, followed by digestive and genitourinary cancers. Research reports and profiles of people (more than 60% of which were about celebrities) were the most common article types. Risk, uncertainty, and clinical trials were also present across several types of cancer news articles. Implications of content trends are discussed as relevant to consumers, producers, health campaign designers, and researchers alike.

Conservation science needs to engage the general public to ensure successful conservation interventions. Although online technologies such as Twitter and Facebook offer new opportunities to accelerate communication between conservation scientists and the online public, factors influencing the spread of conservation news in online media are not well understood. We explored transmission of conservation research through online news articles with generalized linear mixed-effects models and an information theoretic approach. In particular, we assessed differences in the frequency conservation research is featured on online news sites and the impact of online conservation news content and delivery on Facebook likes and shares and Twitter tweets. Five percent of articles in conservation journals are reported in online news, and the probability of reporting depended on the journal. There was weak evidence that articles on climate change and mammals were more likely to be featured. Online news articles about charismatic mammals with illustrations were more likely to be shared or liked on Facebook and Twitter, but the effect of news sites was much larger. These results suggest journals have the greatest impact on which conservation research is featured and that news site has the greatest impact on how popular an online article will be on Facebook and Twitter.
Reports indicate that as the Internet is displacing traditional news sources, younger users continue to be disconnected from the news. Fortunately, the Internet provides new ways of sharing and discussing news stories with others through social networking sites such as Facebook, which may be important for engaging users in the news they read…

Because the volume of information available online is growing at breakneck speed, keeping up with meaning and information communicated by the media and netizens is a new challenge both for scholars and for companies who must address public relations crises. Most current theories and tools are directed at identifying one website or one piece of online news and do not attempt to develop a rapid understanding of all websites and all news covering one topic. This paper represents an effort to integrate statistics, word segmentation, complex networks and visualization to analyze headlines’ keywords and words relationships in online Chinese news using two samples: the 2011 Bohai Bay oil spill and the 2010 Gulf of Mexico oil spill. We gathered all the news headlines concerning the two trending events in the search results from Baidu, the most popular Chinese search engine. We used Simple Chinese Word Segmentation to segment all the headlines into words and then took words as nodes and considered adjacent relations as edges to construct word networks both using the whole sample and at the monthly level. Finally, we develop an integrated mechanism to analyze the features of words’ networks based on news headlines that can account for all the keywords in the news about a particular event and therefore track the evolution of news deeply and rapidly.

The news media has substantial influence on public perceptions of social and health issues. This study conducted a video content analysis to examine portrayals of obese persons in online news reports about obesity. The authors downloaded online news videos about obesity (N = 371) from 5 major news websites and systematically coded visual portrayals of obese and nonobese adults and youth in these videos. The authors found that 65% of overweight/obese adults and 77% of overweight/obese youth were portrayed in a negative, stigmatizing manner across multiple obesity-related topics covered in online news videos. In particular, overweight/obese individuals were significantly more likely than were nonoverweight individuals to be portrayed as headless, with an unflattering emphasis on isolated body parts, from an unflattering rear view of their excess weight, eating unhealthy foods, engaging in sedentary behavior, and dressed in inappropriately fitting clothing. Nonoverweight individuals were significantly more likely to be portrayed positively. In conclusion, obese children and adults are frequently stigmatized in online news videos about obesity. These findings have important implications for public perceptions of obesity and obese persons and may reinforce negative societal weight bias.

This study compared news coverage of genetic cloning research in three online news sites (CNN.com, ABC.com, and MSNBC.com) and three national daily newspapers (The New York Times, The Washington Post, and USA Today). The study involved the analysis of 230 online and print news articles concerning genetic cloning published from 1996 through 1998. Articles were examined with respect to formats, sources, focus, tone, and assessments about the impact of cloning research. Findings indicated that while print news formats remained relatively constant for the duration of this study, online news formats changed significantly with respect to the kinds of media used to represent the news, the layouts used to represent cloning news, and the emphasis placed on audio-visual content. Online stories were as much as 20 to 70% shorter than print stories. More than 50% of the articles appearing online were composed by outside sources (wire services, guest columnists, etc.). By comparison, nearly 90% of the articles published by print newspapers were written "in-house" by science reporters. Online news sites cited fewer sources and cited a smaller variety of sources than the newspapers examined here. In both news outlets, however, the sources most frequently cited were those with vested interests in furthering cloning research. Both online and print news coverage of cloning tends to focus principally on the technical procedures and on the future benefits of cloning. More than 60% of the articles focused on the techniques and technologies of cloning. Less than 25% of the articles focused on social, ethical, or legal issues associated with cloning. Similarly, articles from all six sources (75%) tended to be both positive and future-oriented. Less than 5% of the total articles examined here had a strongly negative or critical tone. Moreover, both online and print news sources increasingly conveyed a strong sense of acceptance about the possibility of human cloning. Data from this study

This cross-national comparative case study of online news production analyzes the strategies of Cable News Network (CNN) and the Norwegian Broadcasting Corporation (NRK), aiming at understanding of the implications of organizational strategy on the role of journalists, explains why traditional media organizations have a tendency to develop a multi-platform approach (distributing content on several platforms, such as television, online, mobile) rather than developing the cross-media (with interplay between media types) or multimedia approach anticipated by both scholars and practitioners.

Hierarchical organization is prevalent in networks representing a wide range of systems in nature and society. An important example is given by the tag hierarchies extracted from large on-line data repositories such as scientific publication archives, file sharing portals, blogs, on-line news portals, etc. The tagging of the stored objects with informative keywords in such repositories has become very common, and in most cases the tags on a given item are free words chosen by the authors independently. Therefore, the relations among keywords appearing in an on-line data repository are unknown in general. However, in most cases the topics and concepts described by these keywords are forming a latent hierarchy, with the more general topics and categories at the top, and more specialized ones at the bottom. There are several algorithms available for deducing this hierarchy from the statistical features of the keywords. In the present work we apply a recent, co-occurrence-based tag hierarchy extraction method to sets of keywords obtained from four different on-line news portals. The resulting hierarchies show substantial differences not just in the topics rendered as important (being at the top of the hierarchy) or of less interest (categorized low in the hierarchy), but also in the underlying network structure. This reveals discrepancies between the plausible keyword association frameworks in the studied news portals. PMID:27802319

Purpose: The purpose of this study was to gain insight into public awareness of intimate partner violence (IPV) in late life by how individuals respond to incidents of IPV reported in the newspaper. Design and Methods: Using grounded theory techniques, online news items covering 24 incidents of IPV in late life, and the reader comments posted to them were analyzed. The news items were examined for incident details, story framing, and reporting style. An open coding process (Charmaz, K. . Constructing grounded theory: A practical guide through qualitative analysis. Thousand Oaks, CA: Sage Publications.) was used to generate a comprehensive understanding of themes and patterns in the comments posted by readers. Results: Few posters indicated that incidents were episodes of IPV. As many posters struggled to make sense of incidents, they attempted to remove guilt from the perpetrator by assigning blame elsewhere. Comments were influenced by personal assumptions and perspectives about IPV, relationships, and old age; reporting style of the news items; and comments posted by other posters. Implications: Altering public views of IPV in late life requires raising awareness through education, reframing the ways in which information is presented, and placing greater emphasis on the context of the violence. By engaging interactive news media, reporters, participatory journalists, and policymakers can enhance public recognition and understanding of IPV in late life. PMID:22547086

West Nile Virus (WNV) has been reported as one of the worst epidemics in US history. This study sought to understand how WNV news stories were framed and how risk information was portrayed from its 1999 arrival in the US through the year 2012. The authors conducted a quantitative content analysis of online news articles obtained through Google News (N = 428). The results of this analysis were compared to the CDC's ArboNET surveillance system. The following story frames were identified in this study: action, conflict, consequence, new evidence, reassurance and uncertainty, with the action frame appearing most frequently. Risk was communicated quantitatively without context in the majority of articles, and only in 2006, the year with the third-highest reported deaths, was risk reported with statistical accuracy. The results from the analysis indicated that at-risk communities were potentially under-informed as accurate risks were not communicated. This study offers evidence about how disease outbreaks are covered in relation to actual disease surveillance data.

The media has the ability to affect public opinion and policy direction. Prevalence of morbid obesity in Canada is increasing; as is the only effective long-term treatment, weight loss surgery (WLS). Limited research has explored media re/presentations of WLS. The purpose of this study was to examine national online news coverage (and reader comments) of WLS using content analysis. We sought to understand the dominant messages being conveyed within the news texts and reader comments, specifically whose voice was represented, who was the intended audience and what was the overall tone. Articles and comments were retrieved from the Canadian Broadcasting Corporation news web site and analysed using line-by-line techniques. Articles were predominantly 'positive/supportive' (63%) in tone and frequently presented the voices and opinions of 'experts' conveying a biomedical perspective. Comments were overwhelmingly 'negative' (56%) and often derogatory including such language as 'piggy' and 'fatty'. Comments were almost exclusively anonymous (99%) and were frequently directed at other commenters (33%) and 'fat' people (6%). The potentially problematic nature of media framing and reader comments, particularly as they could relate to weight-based stigmatization and discrimination is discussed.

Background The aim of this study was to understand online public perceptions of the debate surrounding the choice of annual influenza vaccinations or wearing masks as a condition of employment for healthcare workers, such as the one enacted in British Columbia in August 2012. Methods Four national and 82 local (British Columbia) Canadian online news sites were searched for articles posted between August 2012 and May 2013 containing the words “healthcare workers” and “mandatory influenza vaccinations/immunizations” or “mandatory flu shots and healthcare workers.” We included articles from sources that predominantly concerned our topic of interest and that generated reader comments. Two researchers coded the unedited comments using thematic analysis, categorizing codes to allow themes to emerge. In addition to themes, the comments were categorized by: 1) sentiment towards influenza vaccines; 2) support for mandatory vaccination policies; 3) citing of reference materials or statistics; 4) self-identified health-care worker status; and 5) sharing of a personal story. Results 1163 comments made by 648 commenters responding to 36 articles were analyzed. Popular themes included concerns about freedom of choice, vaccine effectiveness, patient safety, and distrust in government, public health, and the pharmaceutical industry. Almost half (48%) of commenters expressed a negative sentiment toward the influenza vaccine, 28% were positive, 20% were neutral, and 4% expressed mixed sentiment. Of those who commented on the policy, 75% did not support the condition to work policy, while 25% were in favour. Of the commenters, 11% self-identified as healthcare workers, 13% shared personal stories, and 18% cited a reference or statistic. Interpretation The perception of the influenza vaccine in the comment sections of online news sites is fairly poor. Public health agencies should consider including online forums, comment sections, and social media sites as part of their

Methods We searched English- and French-language Canadian news websites for 2012 articles that contained the terms “HPV” or “human papillomavirus.” Articles about HPV vaccinations that contained at least one comment were included. Two researchers independently coded comments, analyzing them for emerging themes. Results We identified 3073 comments from 1198 individuals in response to 71 news articles; 630 (52.6%) individuals expressed positive sentiments about HPV vaccination (2.5 comments/individual), 404 (33.7%) were negative (3.0 comments/individual), 34 (2.8%) were mixed (1.5 comments/individual) and 130 (10.8%) were neutral (1.6 comments/individual). Vaccine-supportive commenters believed the vaccine is safe and effective. Common themes in negative comments included concerns regarding HPV vaccine safety and efficacy, distrust of pharmaceutical companies and government, and belief that school-age children are too young for HPV vaccine. Many comments focused on whether the Catholic Church has the right to inform health policy for students, and discussion often evolved into debates regarding HPV and sexual behaviour. We noted that many individuals doubted the credibility of vaccine safety information. Conclusion The majority of commenters do not appear to be against HPV vaccination, but public health messaging that focuses on both the vaccine’s safety profile, and its use as a means to prevent cancer rather than sexually transmitted HPV infection may facilitate its acceptance.

Consumers facing barriers to healthcare access may use online health information seeking and online communication with physicians, but the empirical relationship has not been sufficiently analyzed. Our study examines the association of barriers to healthcare access with consumers' health-related information searching on the internet, use of health chat groups, and email communication with physicians, using data from 27,210 adults from the 2009 National Health Interview Survey. Individuals with financial barriers to healthcare access, difficulty getting timely appointments with doctors, and conflicts in scheduling during clinic hours are more likely to search for general health information online than those without these access barriers. Those unable to get timely appointments with physicians are more likely to participate in health chat groups and email physicians. The internet may offer a low-cost source of health information and could help meet the heightened demand for health-related information among those facing access barriers to care.

Providing access to the multiple databases essential to nursing practice and education is a challenge for universities and health care providers alike. Collaboration between Wayne State University and other institutions in the Detroit metropolitan area provides a unique system for user access to nursing information. Building on the Detroit Area Library Network (DALNET) structure, additional computer databases have been added to the Library User Information System (LUIS) to allow faculty and student access from remote locations. With university identification, faculty and students access up-to-date literature-searching tools and check the availability of desired journal articles at multiple locations throughout the large tri-county area.

The SAO/NASA Astrophysics Data System (ADS) provides various free services for finding, accessing, and managing bibliographic data, including a basic search form, the myADS notification service, and private library capabilities (a useful tool for building bibliographies), plus access to scanned pages of published articles. The ADS also provides powerful search capabilities, allowing users to find e.g. the most instructive or most important articles on a given subject . For the Planetary Sciences, the citation statistics of the ADS have improved considerably with the inclusion of the references from Elsevier journals, including Icarus, Planetary and Space Science, and Earth and Planetary Science Letters. We currently have about 78 journals convering the planetary and space sciences (Advances in Space Research, Icarus, Solar Physics, Astrophusics and Space Science, JGRE, Meteoritics, to name a few). Currently, this set of journals represents about 180,000 articles and 1.1 million references. Penetration into the Solar Physics, Planetary Sciences and Geophysics community has increased significantly. During the period 2004-2008, user access to JGR and Icarus increased by a factor of 4.4, while e.g. access to the Astrophysical Journal "only" increased by a factor of 1.8.

Objectives To investigate the effect of providing patients online access to their electronic health record (EHR) and linked transactional services on the provision, quality and safety of healthcare. The objectives are also to identify and understand: barriers and facilitators for providing online access to their records and services for primary care workers; and their association with organisational/IT system issues. Setting Primary care. Participants A total of 143 studies were included. 17 were experimental in design and subject to risk of bias assessment, which is reported in a separate paper. Detailed inclusion and exclusion criteria have also been published elsewhere in the protocol. Primary and secondary outcome measures Our primary outcome measure was change in quality or safety as a result of implementation or utilisation of online records/transactional services. Results No studies reported changes in health outcomes; though eight detected medication errors and seven reported improved uptake of preventative care. Professional concerns over privacy were reported in 14 studies. 18 studies reported concern over potential increased workload; with some showing an increase workload in email or online messaging; telephone contact remaining unchanged, and face-to face contact staying the same or falling. Owing to heterogeneity in reporting overall workload change was hard to predict. 10 studies reported how online access offered convenience, primarily for more advantaged patients, who were largely highly satisfied with the process when clinician responses were prompt. Conclusions Patient online access and services offer increased convenience and satisfaction. However, professionals were concerned about impact on workload and risk to privacy. Studies correcting medication errors may improve patient safety. There may need to be a redesign of the business process to engage health professionals in online access and of the EHR to make it friendlier and provide equity of

Online access to medical records and linked services, including requesting repeat prescriptions and booking appointments, enables patients to personalize their access to care. However, online access creates opportunities and challenges for both health professionals and their patients, in practices and in research. The challenges for practice are the impact of online services on workload and the quality and safety of health care. Health professionals are concerned about the impact on workload, especially from email or other online enquiry systems, as well as risks to privacy. Patients report how online access provides a convenient means through which to access their health provider and may offer greater satisfaction if they get a timely response from a clinician. Online access and services may also result in unforeseen consequences and may change the nature of the patient-clinician interaction. Research challenges include: (1) Ensuring privacy, including how to control inappropriate carer and guardian access to medical records; (2) Whether online access to records improves patient safety and health outcomes; (3) Whether record access increases disparities across social classes and between genders; and (4) Improving efficiency. The challenges for practice are: (1) How to incorporate online access into clinical workflow; (2) The need for a business model to fund the additional time taken. Creating a sustainable business model for a safe, private, informative, more equitable online service is needed if online access to records is to be provided outside of pay-for-service systems.

In the past, IPAC has developed its tools and maintained its data archives to be maximally useful to visiting scientists working with IRAS data. With the IRAS data now approaching the 10 year anniversary, IPAC is making the transition to an on-line archive in order to support not only the continuing demand for access to IRAS catalogs and images, but in preparation for providing support for future infrared missions. IPAC's goal is to make all of its key data and services accessible via the Internet. Xcatscan is an on-line service providing access to the IPAC catalogs. IRSKY is a tool for planning observations in the infrared, as well as for browsing the on-line IRAS data products. It is being developed to support the astronomy community in preparing proposals for the European Infrared Space Observatory early next year. These two new services became available on the network last June. We will discuss the design strategy and implementation of these and other systems planned for the future.

Objective: The objective of this study was to determine the number and topical range of available online medical books and to assess how health sciences libraries were providing access to these resources on their public Websites. Method: The collection-based evaluative technique of list checking was used to assess the number and topical range of online medical books of the six largest publishers. Publisher inventory lists were downloaded over a two-day period (May 16–17, 2004). Titles were counted and compared with the 2003 Brandon/Hill list. A sample of health sciences libraries was subsequently derived by consulting the 2004 “Top Medical Schools-Research” in U.S. News & World Report. Bibliographic and bibliothecal access methods were evaluated based on an inspection of the publicly available Websites of the sample libraries. Results: Of 318 currently published online medical books, 151 (47%) were Brandon/Hill titles covering 42 of 59 Brandon/Hill topics (71%). These 151 titles represented 22% (N = 672) of the Brandon/Hill list, which further broke down as 52 minimal core, 41 initial purchase, and 58 other recommended Brandon/Hill titles. These numbers represented 50%, 28%, and 12%, respectively, of all Brandon/Hill titles corresponding to those categories. In terms of bibliographic access, 20 of 21 of sampled libraries created catalog records for their online medical books, 1 of which also provided analytical access at the chapter level, and none provided access at the chapter section level. Of the 21 libraries, 19 had library Website search engines that provided title-level access and 4 provided access at the chapter level and none that at the chapter section level. For bibliothecal access, 19 of 21 libraries provided title-level access to medical books, 8 of which provided classified and alphabetic arrangements, 1 provided a classified arrangement only, and 10 provided an alphabetic arrangement only. No library provided a bibliothecal arrangement for

The Global Earth Observation System of Systems (GEOSS) seeks to address 9 societal benefit areas for Earth observations to address: disasters, health, energy, climate, agriculture, ecosystems, biodiversity, water, and weather. As governments and their partners continue to monitor the face of the Earth, the collection, storage, analysis, and sharing of these observations remain fragmented, incomplete, or redundant. Major observational gaps also remain (particularly as we seek to look beneath the surface of the land and the water). As such, GEO's credo is that "decision makers need a global, coordinated, comprehensive, and sustained system of observing systems." Not surprisingly, one of the largest block of issues facing GEOSS is in the area of data: the access to data (including the building services to make the data more accessible), inadequate data integration and interoperability, error and uncertainty of observations, spatial and temporal gaps in observations, and the related issues of user involvement and capacity building. This is especially for people who stand to gain the most benefit from the datasets, but don't have the resources or knowledge to use them. Esri has millions of GIS and imagery users in hundreds of thousands of organizations around the world that work in the aforementioned 9 GEO societal benefit areas. Esri is therefore proud to have entered into a partnership with GEOSS, more specifically by way of a Memorandum of Understanding (MOU) between Esri and the Earth and Space Science Informatics (ESSI) Laboratory of Prof. Stefano Nativi at the CNR (National Research Council of Italy) Institute of Atmospheric Pollution Research. Esri is working with the ESSI Lab to integrate ArcGIS Online by way of the ArcGIS Online API into the GEOSS Data Access Broker (DAB), resulting in the discoverability of all public content from ArcGIS Online through many of the search portals that participate in this network (e.g., DataOne, CEOS, CUAHSI, OneGeology, IOOS

Oregon State University's Spatial Climate Analysis Service (SCAS) is dedicated to the spatial analysis and mapping of climate. Using the well-known PRISM climate mapping system, SCAS has created digital climate data sets for the US, Canada, parts of Asia and Europe, and elsewhere. Major projects include official USDA precipitation maps for the US, and a new US climate atlas. SCAS also maintains and regularly updates an ongoing monthly time series of digital precipitation, temperature, and dew point maps for the conterminous US, spanning 1895-present. Many PRISM data sets are made accessible to the public online via Web tools that allow users to views map images, download grids, and explore the data. The Minnesota Mapserver has been implemented to allow users to view and query map layers, and create monthly climate time series over the past century for individual grid cells. Time series data are presented as downloadable graphs and tables. Mapserver is also being used by SCAS in a separate Web application, which is geared towards agriculture. In this application, spatial climate and soils data are used to produce suitability maps for various crop species. In the future, we envision greater use of MapServer capabilities for spatial data quality control activities. SCAS is cooperating with the several institutions in developing the WestMap initiative. WestMap aims to provide an easily accessible, comprehensive package of 1 km monthly (or better) resolution climate data series, with associated accuracy estimates, online analysis tools, and educational resources to the highly diverse user communities of climate data stakeholders in the United States.

Patients' access to their online medical records serves as one of the cornerstones in the efforts to increase patient engagement and improve healthcare outcomes. The aim of this article is to provide in-depth understanding of cancer patients' attitudes and experiences of online medical records, as well as an increased understanding of the complexities of developing and launching e-Health services. The study result confirms that online access can help patients prepare for doctor visits and to understand their medical issues. In contrast to the fears of many physicians, the study shows that online access to medical records did not generate substantial anxiety, concerns or increased phone calls to the hospital.

Background Online access to medical records by patients can potentially enhance provision of patient-centred care and improve satisfaction. However, online access and services may also prove to be an additional burden for the healthcare provider. Aim To assess the impact of providing patients with access to their general practice electronic health records (EHR) and other EHR-linked online services on the provision, quality, and safety of health care. Design and setting A systematic review was conducted that focused on all studies about online record access and transactional services in primary care. Method Data sources included MEDLINE, Embase, CINAHL, Cochrane Library, EPOC, DARE, King’s Fund, Nuffield Health, PsycINFO, OpenGrey (1999–2012). The literature was independently screened against detailed inclusion and exclusion criteria; independent dual data extraction was conducted, the risk of bias (RoB) assessed, and a narrative synthesis of the evidence conducted. Results A total of 176 studies were identified, 17 of which were randomised controlled trials, cohort, or cluster studies. Patients reported improved satisfaction with online access and services compared with standard provision, improved self-care, and better communication and engagement with clinicians. Safety improvements were patient-led through identifying medication errors and facilitating more use of preventive services. Provision of online record access and services resulted in a moderate increase of e-mail, no change on telephone contact, but there were variable effects on face-to-face contact. However, other tasks were necessary to sustain these services, which impacted on clinician time. There were no reports of harm or breaches in privacy. Conclusion While the RoB scores suggest many of the studies were of low quality, patients using online services reported increased convenience and satisfaction. These services positively impacted on patient safety, although there were variations of

Online databases have been increasingly used as a key resource in the search for health information. The current study aims to compare the use patterns of online databases between physicians and nurses. A structured questionnaire was mailed to physicians and nurses of randomly selected regional hospitals in Taiwan. Valid questionnaires with complete answers were collected from 544 physicians and 1,573 nurses from November 2008 to February 2009. In general, physicians made more use of online databases than nurses (p < 0.001). They more often accessed English-language online databases (p < 0.001), including MEDLINE, MD Consult, UpToDate, Cochrane Library and ProQuest. On the other hand, nurses accessed Chinese-language online databases more frequently than physicians (p < 0.001). Using a multivariate logistic regression model to adjust the personal characteristics, we found that nurses more often accessed Chinese-language online databases than physicians. Physicians used online databases to locate health information the most for clinical practice (76.6%), followed by instruction preparation (63.3%), and research (57.0%). Nevertheless, nurses used such databases more often for class assignments (66.4%) and clinical practice (55.8%). In conclusion, the behavior and motivation of access to online databases varied between physicians and nurses. Our findings provide evidence in the strategies to enhance the accessing of online databases.

The aim of this study was to investigate whether demographic characteristics and sexual behavior online and offline were associated with private, respectively, nonprivate access to the Internet in a Web sample of people who use the Internet for sexual purposes. A total of 1,913 respondents completed an online questionnaire about Internet sexuality, and 1,614 reported using the Internet for sexual purposes. The majority of these respondents reported having access to an Internet-connected computer no one else had access to (62 percent women and 70 percent men). The results showed that it is possible to differentiate between those who have access to an Internet-connected computer no one else has access to and those who have shared access to an Internet-connected computer. Not only did they differ in demographic characteristics, but also in the sexual activities they engaged in on the Internet. Different patterns were found for women and men. For example, men who had private access to Internet-connected computers were more likely than those who had shared access to seek information about sexual issues. Thus, having access to Internet computers no one else has access to may promote sexual knowledge and health for men. The results of this study along with the technological development implies that in future research, attention should be paid to where and how people access the Internet in relation to online behavior in general and online sexual behavior in particular.

The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is a program for low-income women and children under age five. The purpose of this study was to identify barriers to accessing online WIC resources among Latina WIC clients. Five focus groups were conducted with Spanish-speaking participants recruited from a single WIC clinic. Two key themes emerged relating to barriers in accessing WIC's online resources. The first theme, access issues, included three subthemes: lack of computer/Internet resources; family barriers to computer use; and computer literacy. The second theme, perceived value of the website, included three subthemes: limited time savings; preference for on-site education; and knowledge about the website. This is the first study to evaluate barriers to accessing online resources among Latina women in the WIC program. WIC sites attempting to increase utilization of online resources may be more successful if they serve clients with easy access to a computer with Internet access. They may also consider strategies to increase the value of the online resources, as compared to their current services offered to clients in a face-to-face setting.

Online partner seeking is associated with sexual risk behavior among young adults (specifically men who have sex with men), but this association has yet to be explored among a probability sample of adolescents. Moreover, cell phone internet access and sexual risk taking online and offline have not been explored. A probability sample (N = 1,831) of Los Angeles Unified School District high school students was collected in 2011. Logistic regression models assessed relationships between specific sexual risk behaviors (online sexual solicitation, seeking partners online, sex with internet-met partners, condom use) and frequency of internet use, internet access points, and demographics. Students with cell phone internet access were more likely to report being solicited online for sex, being sexually active, and having sex with an internet-met partner. Bisexual-identifying students reported higher rates of being approached online for sex, being sexually active, and not using condoms at last sex. Gay, lesbian, and questioning (GLQ) students were more likely to report online partner seeking and unprotected sex at last sex with an internet-met partner. Additionally, having sex with an internet-met partner was associated with being male, online sexual solicitation, and online partner seeking. Internet- and school-based sexual health programs should incorporate safety messages regarding online sexual solicitation, seeking sex partners online, and engaging in safer sex practices with all partners. Programs must target adolescents of all sexual identities, as adolescents may not yet be "out," and bisexual and GLQ adolescents are more likely to engage in risky sex behaviors.

Background In March 2012, the US Centers for Disease Control and Prevention (CDC) launched the first-ever paid national tobacco education campaign. At a cost of US $54 million, “Tips from Former Smokers” (Tips) ran for 3 months across multiple media, depicting the suffering experienced by smokers and their families in graphic detail. The potential impact and reach of the Tips campaign was not limited to that achieved through paid media placements. It was also potentially extended through “earned media”, including news and blog coverage of the campaign. Such coverage can shape public understanding of and facilitate public engagement with key health issues. Objective To better understand the contribution of earned media to the public’s engagement with health issues in the current news media environment, we examined the online “earned media” and public engagement generated by one national public health campaign. Methods We constructed a purposive sample of online media coverage of the CDC’s 2012 Tips from Former Smokers television campaign, focusing on 14 influential and politically diverse US news outlets and policy-focused blogs. We identified relevant content by combining campaign and website-specific keywords for 4 months around the campaign release. Each story was coded for content, inclusion of multimedia, and measures of audience engagement. Results The search yielded 36 stories mentioning Tips, of which 27 were focused on the campaign. Story content between pieces was strikingly similar, with most stories highlighting the same points about the campaign’s content, cost, and potential impact. We saw notable evidence of audience engagement; stories focused on Tips generated 9547 comments, 8891 Facebook “likes”, 1027 tweets, and 505 story URL shares on Facebook. Audience engagement varied by story and site, as did the valence and relevance of associated audience comments. Comments were most oppositional on CNN and most supportive on Yahoo

To better understand the dynamics of online student test taking, including the likelihood of cheating by large numbers of students, we examined test-taking patterns and outcomes of weekly online quizzes in two large undergraduate biology lecture courses. Students taking a quiz late in a 1-3-day quiz access period performed 10-15% worse on quizzes than the students who completed the quiz early. Quiz access time was also negatively correlated with performance in other course components and course grades. These patterns suggest that academic dishonesty was not a determinant in unsupervised online quiz performance. Students generally completed quizzes in late afternoon or evening hours, but students who completed quizzes between midnight and 8 a.m. had significantly lower quiz grades than their peers. In addition, upper-division students were more likely to characterize weekly online quizzes as more helpful for their learning than the lower-division students.

The LHCb collaboration consists of roughly 700 physicists from 52 institutes and universities. Most of the collaborating physicists - including subdetector experts - are not permanently based at CERN. This paper describes the architecture used to publish data internal to the LHCb experiment control- and data acquisition system to the World Wide Web. Collaborators can access the online (sub-) system status and the system performance directly from the institute abroad, from home or from a smart phone without the need of direct access to the online computing infrastructure.

With the continuous growth of internet usage, Google Trends has emerged as a source of information to investigate how social trends evolve over time. Knowing how the level of interest in conservation topics--approximated using Google search volume--varies over time can help support targeted conservation science communication. However, the evolution of search volume over time and the mechanisms that drive peaks in searches are poorly understood. We conducted time series analyses on Google search data from 2004 to 2013 to investigate: (i) whether interests in selected conservation topics have declined and (ii) the effect of news reporting and academic publishing on search volume. Although trends were sensitive to the term used as benchmark, we did not find that public interest towards conservation topics such as climate change, ecosystem services, deforestation, orangutan, invasive species and habitat loss was declining. We found, however, a robust downward trend for endangered species and an upward trend for ecosystem services. The quantity of news articles was related to patterns in Google search volume, whereas the number of research articles was not a good predictor but lagged behind Google search volume, indicating the role of news in the transfer of conservation science to the public.

Online reprint request (ORR) is the standard protocol to obtain the reprints (e-print/hard copy) using the internet (author's e-mail address) when the required literature is not available. The problem of higher cost of surface mail for the author and the reader, as well as the time taken to receive postal reprints, is overcome by ORR. This technique has its limitation in message failure, expiration of mail (e-mail decay), or journal not providing author's e-mail address. This article analyzes the available practical solution to overcome these barriers. This process facilitates the exchange of scientific information. In e-mail decay, reprint request can be sent in the following order: a) search and send to author's latest e-mail address, b) co-author's latest or affiliated institution's e-mail address, c) postal reprint request providing the requestor's e-mail address. This protocol can be practiced when library facilities or required literature is not available. Literature can be pooled and used for residency teaching programs, like group discussions, journal clubs, and e-learning exercises (teleeducation), to update the recent advances for practice and research.

Network-based facilities will allow researchers at different locations to collaborate on experiments as if they all were together in the same laboratory. The expected value of these geographically distributed environments includes substantially increased effectiveness in doing science, and an enabling capability for analytical and high-value production use by industry. The Distributed, Collaboratory Experiment Environments (DCEE) Program consists of four projects that were established to build prototype remote experiment and collaborative environments. The work undertaken in this project represents some of the research and development of the mechanisms and infrastructure required to make collaboratories a reality. Some of these mechanisms have already been developed. Several other mechanisms, such as data dissemination, resource management for the sharing of experiment control, safety and security, electronic notebooks, elements of telepresence, and integrated user interfaces need further research and development. The pilot application for these collaborative tools is the Advanced Light Source (ALS) Beamline 7.0 at the Ernest Orlando Lawrence Berkeley Laboratory. The ALS is a particle accelerator and is a source of very high brilliance soft X-ray beams. One experimental facility is the Spectro-Microscopy Facility Beamline 7.0. Through this project, the Spectro-Microscopy Facility will be opened up to users from a wide range of organizations. The goal is to build software that will not only put the ALS Beamline 7.0 on-line, but will also serve as building blocks for future collaboratory development.

Personal News Retrieval System is a client-server application that delivers news segments on demand in a variety of information networks. At the server side, the news stories are segmented out from the digitized TV broadcast then classified and filtered based on consumers' preferences. At the client side, the user can access the preferred video news through the Web and watch stored video news in preferred order. Browsing preferences can be set based on anchorperson, broadcaster, category, location, top- stories and keywords. This system can be used to set up a news service run by content providers or independent media distribution companies. However, in the news era of enhanced PC/TV appliances, it is foreseeable that the whole system can run in the living room on a personal device. This paper describes the chosen server architecture, limitation of the system and solutions that can be implemented in the future.

The purpose of the online resource presented here, POPcorn (Project Portal for corn), is to enhance accessibility of maize genetic and genomic resources for plant biologists. Currently, many online locations are difficult to find, some are best searched independently, and individual project websites often degrade over time—sometimes disappearing entirely. The POPcorn site makes available (1) a centralized, web-accessible resource to search and browse descriptions of ongoing maize genomics projects, (2) a single, stand-alone tool that uses web Services and minimal data warehousing to search for sequence matches in online resources of diverse offsite projects, and (3) a set of tools that enables researchers to migrate their data to the long-term model organism database for maize genetic and genomic information: MaizeGDB. Examples demonstrating POPcorn's utility are provided herein. PMID:22253616

Background Although today's youth are interested in using the internet to access and manage information related to their health, little information exists about parental attitudes towards the release of health information to adolescents. Methods Structured interviews were conducted with the parents of 83 adolescents detained at a large Northern California juvenile detention facility to examine parental perceptions toward allowing their children online access to their own health information. Results The majority of parents interviewed (70%) wanted their children to have online access to their own health information. Seventy-nine percent of these parents were also comfortable allowing their children to choose with whom they would share this information. Conclusions This study is one of the first to examine parental attitudes towards providing adolescents access to their own health information, and the first among parents of underserved youth. This study demonstrates that parents may be quite supportive of allowing their adolescent children to have secure online access to their own health information. PMID:27595043

Internet use is widespread, but little is known about Internet use for cancer information among Latinos, especially those who rely on safety net clinics. The authors investigated access to and intended use of the Internet for cancer information among low income, immigrant Latinos predominately from Central and South America. A cross-sectional study of 1,273 Latinos 21 years and older attending safety net clinics or health fairs was conducted from June 2007 to November 2008. The authors used logistic regression models to evaluate associations of age, acculturation, psychosocial factors and other covariates with Internet access and intended use of the Internet for cancer information among those with access. Of the sample, 44% reported Internet access. Higher information self-efficacy and greater trust in the Internet were independently associated with Internet access (p = .05 and p < .001, respectively). Among those with access, 53.8% reported they intended to seek cancer help online if they needed information. Those with younger age and higher acculturation, education and self-efficacy had higher odds of intended Internet use for cancer information, considering covariates. In addition, those with high (vs. low) perceived risk of cancer (OR = 1.76; 95% CI [1.14, 2.73]; p = .01) and higher levels of trust in online health information (OR = 1.47 per one-point increase; 95% [CI 1.19, 1.82]; p = .0004) were more likely to intend to seek cancer information online. These findings that Internet access is fairly high in the immigrant Latino population and that the Internet is a trusted source of cancer information suggest that the Internet may be a channel for cancer control interventions.

We developed an online multimedia event detection (MED) system. However, there are a secure access control issue and a large scale robust representation issue when we want to integrate traditional event detection algorithms into the online environment. For the first issue, we proposed a tree proxy-based and service-oriented access control (TPSAC) model based on the traditional role based access control model. Verification experiments were conducted on the CloudSim simulation platform, and the results showed that the TPSAC model is suitable for the access control of dynamic online environments. For the second issue, inspired by the object-bank scene descriptor, we proposed a 1000-object-bank (1000OBK) event descriptor. Feature vectors of the 1000OBK were extracted from response pyramids of 1000 generic object detectors which were trained on standard annotated image datasets, such as the ImageNet dataset. A spatial bag of words tiling approach was then adopted to encode these feature vectors for bridging the gap between the objects and events. Furthermore, we performed experiments in the context of event classification on the challenging TRECVID MED 2012 dataset, and the results showed that the robust 1000OBK event descriptor outperforms the state-of-the-art approaches.

There has been an explosive increase in the population of the OSN (online social network) in recent years. The OSN provides users with many opportunities to communicate among friends and family. Further, it facilitates developing new relationships with previously unknown people having similar beliefs or interests. However, the OSN can expose users to adverse effects such as privacy breaches, the disclosing of uncontrolled material, and the disseminating of false information. Traditional access control models such as MAC, DAC, and RBAC are applied to the OSN to address these problems. However, these models are not suitable for the dynamic OSN environment because user behavior in the OSN is unpredictable and static access control imposes a burden on the users to change the access control rules individually. We propose a dynamic trust-based access control for the OSN to address the problems of the traditional static access control. Moreover, we provide novel criteria to evaluate trust factors such as sociological approach and evaluate a method to calculate the dynamic trust values. The proposed method can monitor negative behavior and modify access permission levels dynamically to prevent the indiscriminate disclosure of information. PMID:25374943

The increasing need of remote medical investigation services in the framework of collaborative multidisciplinary meetings (e.g. cancer follow-up) raises the challenge of on-line remote access of (large amount of) radiologic data in a limited period of time. This paper proposes a scalable compression framework of DICOM images providing low-latency display through low speed networks. The developed approach relies on useless information removal from images (i.e. not related with the patient body) and the exploitation of the JPEG2000 standard to achieve progressive quality encoding and access of the data. This mechanism also allows the efficient exploitation of any idle times (corresponding to on-line visual image analysis) to download the remaining data at lossless quality in a way transparent to the user, thus minimizing the perceived latency.

Massive open online courses (MOOCs) are often characterized as remedies to educational disparities related to social class. Using data from 68 MOOCs offered by Harvard and MIT between 2012 and 2014, we found that course participants from the United States tended to live in more-affluent and better-educated neighborhoods than the average U.S. resident. Among those who did register for courses, students with greater socioeconomic resources were more likely to earn a certificate. Furthermore, these differences in MOOC access and completion were larger for adolescents and young adults, the traditional ages where people find on-ramps into science, technology, engineering, and mathematics (STEM) coursework and careers. Our findings raise concerns that MOOCs and similar approaches to online learning can exacerbate rather than reduce disparities in educational outcomes related to socioeconomic status.

Abstract Background Prospective orthopedic residency applicants commonly use one of three databases to identify potential programs: Accreditation Council of Graduate Medical Education (ACGME), American Medical Association (FREIDA), or Orthogate. org. In addition, institutional websites are typically the primary source of information once programs are identified. We sought to evaluate the databases and websites used by prospective orthopedic surgery applicants for content and accessibility. We hypothesized that information would be more available in comparison to previous studies but would still fail to provide complete, up to date program information for the prospective applicant. Methods Three online databases were queried in December 2014 to compile a list of orthopedic residency programs in the United States. This combined list was used as a basis for evaluating individual institution websites. Previously described criteria were used to evaluate the availability of information contained within orthopedic surgery residency websites. Results At the time of online review, 157 programs were identified. Depending on the database in question, up to 33% of programs either did not provide a link or listed a non-functioning link. Among the variety of evaluated criteria, inclusion of the information varied between 12% and 97% for the individual program websites. Conclusions Online databases are useful in listing programs, but individual program details and direct functional links are lacking. Most program websites contain varying degrees of desired information; however, not all programs maintain websites which consistently provide information to satisfy the evaluated criteria in this study. Improved online accessibility and availability of information for residency programs would increase their visibility and utility for prospective applicants. PMID:27528832

Social media is fundamentally altering how we access health information and make decisions about medical treatment, including for terminally ill patients. This specifically includes the growing phenomenon of patients who use online petitions and social media campaigns in an attempt to gain access to experimental drugs through expanded access pathways. Importantly, controversy surrounding expanded access and "compassionate use" involves several disparate stakeholders, including patients, manufacturers, policymakers, and regulatory agencies-all with competing interests and priorities, leading to confusion, frustration, and ultimately advocacy. In order to explore this issue in detail, this correspondence article first conducts a literature review to describe how the expanded access policy and regulatory environment in the United States has evolved over time and how it currently impacts access to experimental drugs. We then conducted structured web searches to identify patient use of online petitions and social media campaigns aimed at compelling access to experimental drugs. This was carried out in order to characterize the types of communication strategies utilized, the diseases and drugs subject to expanded access petitions, and the prevalent themes associated with this form of "digital" patient advocacy. We find that patients and their families experience mixed results, but still gravitate towards the use of online campaigns out of desperation, lack of reliable information about treatment access options, and in direct response to limitations of the current fragmented structure of expanded access regulation and policy currently in place. In response, we discuss potential policy reforms to improve expanded access processes, including advocating greater transparency for expanded access programs, exploring use of targeted economic incentives for manufacturers, and developing systems to facilitate patient information about existing treatment options. This includes

Advanced Very High Resolution Radiometer and Geostationary Operational Environmental Satellite imagery, received by antennas located at the University of Colorado, are made available to the Internet users through an on-line data access system. Created as a 'test bed' system for the National Aeronautics and Space Administration's future Earth Observing System Data and Information System, this test bed provides an opportunity to test both the technical requirements of an on-line data system and the different ways in which the general user community would employ such a system. Initiated in December 1991, the basic data system experiment four major evolutionary changes in response to user requests and requirements. Features added with these changes were the addition of on-line browse, user subsetting, and dynamic image processing/navigation. Over its lifetime the system has grown to a maximum of over 2500 registered users, and after losing many of these users due to hardware changes, the system is once again growing with its own independent mass storage system.

News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include:
Total Pages Served 361,115
Total Visits 138,377
Total Unique Visitors 51,744
Total Repeat Visitors 11,536
Average Visit Length 03:05
Average Requests/Visit 10.8
Average Pages/Visit 2.6
Average Daily Visits 916 Online Rationale and Expectations JCE Online is a very important part of the whole Journal, but we do not expect it to supplant print: online and print are very different media. Usage of JCE Online is growing steadily; our subscribers are realizing what we have learned: it is not possible to deliver the Journal in the print medium alone- print is no longer adequate to accomplish our mission. Examples of things not possible in print include:

News on GNVQ science The Institute of Physics and the Royal Society of Chemistry are currently financing the compilation of a directory of resources to assist teachers in identifying and selecting suitable materials for teaching the new GNVQ science specifications. Work on the first part of the directory will soon be completed and it is hoped to publish the material in both print and electronic forms before the end of the summer term. This first part covers resources - all evaluated by practising GNVQ teachers - supporting the teaching of the compulsory units for Advanced GNVQ Science. A small team comprising a physics teacher, a chemistry teacher and a biology teacher, all involved with GNVQ programmes and led by Dr Ken Gadd, has carried out the work. They have established a network of teachers around the country to help with the evaluation of curriculum materials. The next part of the project will be to examine the feasibility of providing a similar listing for the optional units at this level. Future development, depending on the availability of funds, will extend the project to Intermediate level programmes in science, including the Part One, once its structure has been agreed at QCA. Further information about the Directory and the next phase of development will be available in the autumn. Activities Physics on Stage The future of science, technology and the ensuing wealth creation potential for Britain will depend on the quality of science education in schools today. Yet the numbers studying physics, which underpins science and engineering, are falling. This problem is currently

We present an organic materials database (OMDB) hosting thousands of Kohn-Sham electronic band structures, which is freely accessible online at http://omdb.diracmaterials.org. The OMDB focus lies on electronic structure, density of states and other properties for purely organic and organometallic compounds that are known to date. The electronic band structures are calculated using density functional theory for the crystal structures contained in the Crystallography Open Database. The OMDB web interface allows users to retrieve materials with specified target properties using non-trivial queries about their electronic structure. We illustrate the use of the OMDB and how it can become an organic part of search and prediction of novel functional materials via data mining techniques. As a specific example, we provide data mining results for metals and semiconductors, which are known to be rare in the class of organic materials. PMID:28182744

Little is known about how listeners represent another person's spatial perspective during language processing (e.g., two people looking at a map from different angles). Can listeners use contextual cues such as speaker identity to access a representation of the interlocutor's spatial perspective? In two eye-tracking experiments, participants received auditory instructions to move objects around a screen from two randomly alternating spatial perspectives (45° vs. 315° or 135° vs. 225° rotations from the participant's viewpoint). Instructions were spoken either by one voice, where the speaker's perspective switched at random, or by two voices, where each speaker maintained one perspective. Analysis of participant eye-gaze showed that interpretation of the instructions improved when each viewpoint was associated with a different voice. These findings demonstrate that listeners can learn mappings between individual talkers and viewpoints, and use these mappings to guide online language processing.

Advanced cyberinfrastructure capabilities are enabling end-to-end management of data flows in observing system networks and online access to very large data archives. We provide an overview of several projects in earth and environmental sciences that have developed and deployed cyberinfrastructure for collecting and organizing field observations and remote sensing data, to make them available to a community of users. The data cyberinfrastructure framework should cover the range from data acquisition, quality control, data archiving, discovery, access, integration, and modeling. Using examples from different earth and environmental science cyberinfrastructure efforts, we will describe the state of the art in data cyberinfrastructure and future directions and challenges. The Tropical Ecology, Assessment and Monitoring (TEAM) Network (http://teamnetwork.org), which is a network of forested sites—currently consisting of 15 sites, and growing—distributed across Central America, South America, Africa, and Asia. Each site implements a standardized set of data collection protocols, all under the control of a common cyberinfrastructure. The data are available via a portal from a central site, but with appropriate access controls. The TEAM Network is run by Conservation International, in partnership with the Wildlife Conservation Society, Smithsonian Institute, and the Missouri Botanical Gardens, and is funded by the Moore Foundation. The EarthScope Data Portal (portal.earthscope.org) implements a virtual metadata catalog and a data cart to provides a means for simultaneously exploring EarthScope's various instrument networks, as well as seamlessly downloading data from multiple stations and instrument types. The prototype of the US Geoinformatics Information Network (US GIN) project is implementing a federated catalog, using the Catalog Services for Web (CSW) standard. The NSF-funded Opentopography.org—a spinoff of the GEON project, www.geongrid.org—provides online
access to Physics World or Physics Education . We will endeavour to provide more details about this as soon as we can. Another recently approved idea is that of a new class of Institute membership for school students and this also will be explained at a later date.

Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

Online research methodologies may serve as an important mechanism for population-focused data collection in social work research. Online surveys have become increasingly prevalent in research inquiries with young people and have been acknowledged for their potential in investigating understudied and marginalized populations and subpopulations, permitting increased access to communities that tend to be less visible-and thus often less studied-in offline contexts. Lesbian, gay, bisexual, transgender, and queer (LGBTQ) young people are a socially stigmatized, yet digitally active, youth population whose participation in online surveys has been previously addressed in the literature. Many of the opportunities and challenges of online survey research identified with LGBTQ youths may be highly relevant to other populations of marginalized and hard-to-access young people, who are likely present in significant numbers in the online environment (for example, ethnoracialized youths and low-income youths). In this article, the utility of online survey methods with marginalized young people is discussed, and recommendations for social work research are provided.

Topography data acquired with lidar (light detection and ranging) technology are revolutionizing the way we study the Earth's surface and overlying vegetation. These data, collected from satellite, airborne, tripod, or mobile-mounted scanners have emerged as a fundamental tool for research on topics including earthquake hazards, hillslope processes, and cyrosphere change. The U.S. National Science Foundation-funded OpenTopography (OT) Facility (http://www.opentopography.org) is a web-based system designed to democratize access to earth science-oriented lidar topography data. OT provides free, online access to lidar data in a number of forms, including the point cloud and associated geospatial-processing tools for customized analysis. The point cloud data are co-located with on-demand processing tools to generate digital elevation models, and derived products and visualizations which allow users to quickly access data in a format appropriate for their scientific application. The OT system is built using a service-oriented architecture (SOA) that leverages cyberinfrastructure resources at the San Diego Supercomputer Center at the University of California San Diego to allow users, regardless of expertise, to access these massive lidar datasets and derived raster data products for use in research and teaching. OT hosts over 600 billion lidar returns covering more than 120,000 km2. These data are provided by a variety of partners under joint agreements and memoranda of understanding with OT. Partners include national facilities such as the NSF-funded National Center for Airborne Lidar Mapping (NCALM), as well as non-governmental organizations and local, state, and federal agencies. OT has become a hub for high-resolution topography resources. Datasets hosted by other organizations, as well as lidar-specific software, can be registered into the OT catalog, providing users a 'one-stop shop' for such information. OT is also a partner on the NASA Lidar Access System (NLAS
