Sexual reference display on a social networking web site (SNS) is associated with self-reported sexual intention; females are more likely to display sexually explicit content on SNSs. The purpose of this study was to investigate male college students' views towards sexual references displayed on publicly available SNSs by females. Focus groups. One large state university. Male college students age 18-23. All tape recorded discussion was fully transcribed, then discussed to determine thematic consensus. A trained male facilitator asked participants about views on sexual references displayed on SNSs by female peers and showed examples of sexual references from female's SNS profiles to facilitate discussion. A total of 28 heterosexual male participants participated in seven focus groups. Nearly all participants reported using Facebook to evaluate potential female partners. Three themes emerged from our data. First, participants reported that displays of sexual references on social networking web sites increased sexual expectations. Second, sexual reference display decreased interest in pursuing a dating relationship. Third, SNS data was acknowledged as imperfect but valuable. Females who display sexual references on publicly available SNS profiles may be influencing potential partners' sexual expectations and dating intentions. Future research should examine females' motivations and beliefs about displaying such references and educate women about the potential impact of these sexual displays.

Exposure to alcohol use in media is associated with adolescent alcohol use. Adolescents frequently display alcohol references on Internet media, such as social networking web sites. The purpose of this study was to conduct a theoretically based content analysis of older adolescents' displayed alcohol references on a social networking web site. We evaluated 400 randomly selected public MySpace profiles of self-reported 17- to 20-year-olds from zip codes, representing urban, suburban, and rural communities in one Washington county. Content was evaluated for alcohol references, suggesting: (1) explicit versus figurative alcohol use, (2) alcohol-related motivations, associations, and consequences, including references that met CRAFFT problem drinking criteria. We compared profiles from four target zip codes for prevalence and frequency of alcohol display. Of 400 profiles, 225 (56.3%) contained 341 references to alcohol. Profile owners who displayed alcohol references were mostly male (54.2%) and white (70.7%). The most frequent reference category was explicit use (49.3%); the most commonly displayed alcohol use motivation was peer pressure (4.7%). Few references met CRAFFT problem drinking criteria (3.2%). There were no differences in prevalence or frequency of alcohol display among the four sociodemographic communities. Despite alcohol use being illegal and potentially stigmatizing in this population, explicit alcohol use is frequently referenced on adolescents' MySpace profiles across several sociodemographic communities. Motivations, associations, and consequences regarding alcohol use referenced on MySpace appear consistent with previous studies of adolescent alcohol use. These references may be a potent source of influence on adolescents, particularly given that they are created and displayed by peers. (c) 2010 Society for Adolescent Health and Medicine.

This paper describes information technology being developed to improve the quality, sophistication, accessibility, and pedagogical simplicity of ecological network data, analysis, and visualization. We present designs for a WWW demonstration/prototype web site that provides database, analysis, and visualization tools for research and education related to food web research. Our early experience with a prototype 3D ecological network visualization guides our design of a more flexible architecture design. 3D visualization algorithms include variable node and link sizes, placements according to node connectivity and tropic levels, and visualization of other node and link properties in food web data. The flexible architecture includes an XML application design, FoodWebML, and pipelining of computational components. Based on users" choices of data and visualization options, the WWW prototype site will connect to an XML database (Xindice) and return the visualization in VRML format for browsing and further interactions.

Development of a laboratory niche Web site.

Science.gov (United States)

Dimenstein, Izak B; Dimenstein, Simon I

2013-10-01

This technical note presents the development of a methodological laboratory niche Web site. The "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) Web site is used as an example. Although common steps in creation of most Web sites are followed, there are particular requirements for structuring the template's menu on methodological laboratory Web sites. The "nested doll principle," in which one object is placed inside another, most adequately describes the methodological approach to laboratory Web site design. Fragmentation in presenting the Web site's material highlights the discrete parts of the laboratory procedure. An optimally minimal triad of components can be recommended for the creation of a laboratory niche Web site: a main set of media, a blog, and an ancillary component (host, contact, and links). The inclusion of a blog makes the Web site a dynamic forum for professional communication. By forming links and portals, cloud computing opens opportunities for connecting a niche Web site with other Web sites and professional organizations. As an additional source of information exchange, methodological laboratory niche Web sites are destined to parallel both traditional and new forms, such as books, journals, seminars, webinars, and internal educational materials.

WebScore: An Effective Page Scoring Approach for Uncertain Web Social Networks

Directory of Open Access Journals (Sweden)

Shaojie Qiao

2011-10-01

Full Text Available To effectively score pages with uncertainty in web social networks, we first proposed a new concept called transition probability matrix and formally defined the uncertainty in web social networks. Second, we proposed a hybrid page scoring algorithm, called WebScore, based on the PageRank algorithm and three centrality measures including degree, betweenness, and closeness. Particularly,WebScore takes into a full consideration of the uncertainty of web social networks by computing the transition probability from one page to another. The basic idea ofWebScore is to: (1 integrate uncertainty into PageRank in order to accurately rank pages, and (2 apply the centrality measures to calculate the importance of pages in web social networks. In order to verify the performance of WebScore, we developed a web social network analysis system which can partition web pages into distinct groups and score them in an effective fashion. Finally, we conducted extensive experiments on real data and the results show that WebScore is effective at scoring uncertain pages with less time deficiency than PageRank and centrality measures based page scoring algorithms.

The backdoor or information leak of Web servers can be detected by using Web Mining techniques on some abnormal Web log and Web application log data. The security of Web servers can be enhanced and the damage of illegal access can be avoided. Firstly, the system for discovering the patterns of information leakages in CGI scripts from Web log data was proposed. Secondly, those patterns for system administrators to modify their codes and enhance their Web site security were provided. The following aspects were described: one is to combine web application log with web log to extract more information, so web data mining could be used to mine web log for discovering the information that firewall and Information Detection System cannot find. Another approach is to propose an operation module of web site to enhance Web site security. In cluster server session, Density-Based Clustering technique is used to reduce resource cost and obtain better efficiency.

2013-01-01

Social networking sites like Facebook may be a powerful tool for increasing rates of live kidney donation. They allow for wide dissemination of information and discussion and could lessen anxiety associated with a face-to-face request for donation. However, sparse data exist on the use of social media for this purpose. We searched Facebook, the most popular social networking site, for publicly available English-language pages seeking kidney donors for a specific individual, abstracting information on the potential recipient, characteristics of the page itself, and whether potential donors were tested. In the 91 pages meeting inclusion criteria, the mean age of potential recipients was 37 (range: 2-69); 88% were US residents. Other posted information included the individual's photograph (76%), blood type (64%), cause of kidney disease (43%), and location (71%). Thirty-two percent of pages reported having potential donors tested, and 10% reported receiving a live-donor kidney transplant. Those reporting donor testing shared more potential recipient characteristics, provided more information about transplantation, and had higher page traffic. Facebook is already being used to identify potential kidney donors. Future studies should focus on how to safely, ethically, and effectively use social networking sites to inform potential donors and potentially expand live kidney donation. © 2013 John Wiley & Sons A/S.

Go ahead, visit those web sites, you can`t get hurt, can you?

Energy Technology Data Exchange (ETDEWEB)

Rothfuss, J.S.; Parrett, J.W.

1997-02-01

Browsing (surfing) the World Wide Web (the web) has exploded onto the Internet with an unprecedented popularity. Fueled by massive acceptance, the web client/server technology is leaping forward with a speed that competes with no other software technology. The primary force behind this phenomenon is the simplicity of the web browsing experience. People who have never touched a computer before can now perform sophisticated network tasks with a simple point-and-click. Unfortunately, this simplicity gives many, if not most, web wanderers the impression that the web browser is risk free, nothing more than a high powered television. This misconception is dangerous by creating the myth that a user visiting a web site is immune from subversive or malicious intent. While many want you to believe that surfing the web is as simple as using any other household appliance, it is not like surfing television channels, it is bi-directional. You can learn a lot of useful information from web sites. But, either directly or indirectly, others can also learn quite a bit about you. Of even more concern is a web sites` potential ability to exert control over the local computer. This paper tries to consolidate some of the current concerns that you should consider as you jump into the surf.

Full Text Available Social networking sites, a web-based application have permeated the boundary between personal lives and student lives. Nowadays, students in higher learning used social networking site such as Facebook to facilitate their learning through the academic collaboration which it further enhances students’ social capital. Social networking site has many advantages to improve students’ learning. To date, Facebook is the leading social networking sites at this time which it being widely used by students in higher learning to communicate to each other, to carry out academic collaboration and sharing resources. Learning through social networking sites is based on the social interaction which learning are emphasizing on students, real world resources, active students` participation, diversity of learning resources and the use of digital tools to deliver meaningful learning. Many studies found the positive, neutral and negative impact of social networking sites on academic performance. Thus, this study will determine the relationship between Facebook usage and academic achievement. Also, it will investigate the association of social capital and academic collaboration to Facebook usage.

2008-01-01

Today the World Wide Web is undergoing a subtle but profound shift to Web 2.0, to become more of a social web. The use of collaborative technologies such as blogs and social networking site (SNS) leads to instant online community in which people communicate rapidly and conveniently with each other. Moreover, there are growing interest and concern regarding the topological structure of these new online social networks. In this paper, we present empirical analysis of statistical properties of two important Chinese online social networks-a blogging network and an SNS open to college students. They are both emerging in the age of Web 2.0. We demonstrate that both networks possess small-world and scale-free features already observed in real-world and artificial networks. In addition, we investigate the distribution of topological distance. Furthermore, we study the correlations between degree (in/out) and degree (in/out), clustering coefficient and degree, popularity (in terms of number of page views) and in-degree (for the blogging network), respectively. We find that the blogging network shows disassortative mixing pattern, whereas the SNS network is an assortative one. Our research may help us to elucidate the self-organizing structural characteristics of these online social networks embedded in technical forms.

A review of influenza detection and prediction through social networking sites.

Science.gov (United States)

Alessa, Ali; Faezipour, Miad

2018-02-01

Early prediction of seasonal epidemics such as influenza may reduce their impact in daily lives. Nowadays, the web can be used for surveillance of diseases. Search engines and social networking sites can be used to track trends of different diseases seven to ten days faster than government agencies such as Center of Disease Control and Prevention (CDC). CDC uses the Illness-Like Influenza Surveillance Network (ILINet), which is a program used to monitor Influenza-Like Illness (ILI) sent by thousands of health care providers in order to detect influenza outbreaks. It is a reliable tool, however, it is slow and expensive. For that reason, many studies aim to develop methods that do real time analysis to track ILI using social networking sites. Social media data such as Twitter can be used to predict the spread of flu in the population and can help in getting early warnings. Today, social networking sites (SNS) are used widely by many people to share thoughts and even health status. Therefore, SNS provides an efficient resource for disease surveillance and a good way to communicate to prevent disease outbreaks. The goal of this study is to review existing alternative solutions that track flu outbreak in real time using social networking sites and web blogs. Many studies have shown that social networking sites can be used to conduct real time analysis for better predictions.

The absence of scientific data forces orthodontists to guess at how best to design Internet sites that persuade prospective patients to call for appointments. This study was conducted to identify the Web-site factors that lead prospective patients to make appointments or, conversely, to reject a practice. Ten participants actively looking online for an orthodontist were recruited to participate. They reviewed 64 orthodontic Web sites in their geographic areas and rated their likelihood of calling each practice for an appointment. The sessions were videotaped. Analysis of participant comments, navigation patterns, and ratings suggested 25 distinguishing factors. Statistical analysis showed 10 Web-site characteristics that predict the success of an orthodontic Web site in attracting new patients.

Clicking for friendship: social network sites and the medium of personhood

Directory of Open Access Journals (Sweden)

Rebecca Shryock

2010-11-01

Full Text Available Social networking sites such as MySpace and Facebook depend on familiar social resources, including language, reading/writing and established semantic constructs such as personhood, privacy and friends. However, the use of computers, the Web 2.0 platform, and the latest networking software are revolutionising how “personhood” and “friendship” are produced by communication. We refer to the media theory of Niklas Luhmann to identify specific differences in how communication is organised and reproduced on networking sites. The electronic medium appears to be changing the way participants selectively construct and bind expectations of personhood and communicative ties to themselves and others. Using software available on the Web, users confront each other as digital bodies, as participants in communication, available for friendship within a new “ether of interactivity”.

Web-based networking within the framework of ANENT

International Nuclear Information System (INIS)

Han, K.W.; Lee, E.J.; Kim, Y.T.; Nam, Y.M.

2004-01-01

Recognizing the importance of nuclear knowledge management, KAERI has been actively involved in the establishment of the IAEA Asian Network for Higher Education in Nuclear Technology (ANENT). The institute, on behalf of the Korean government, initiated discussions with the IAEA on the concept of ANENT and hosted an IAEA Consultant Meeting in July 2003, which was intended to prepare a draft report for the establishment of ANENT. From the preparatory stage, the institute volunteered to establish a website to support the ANENT activities. This led the ANENT Coordination Committee, at its first meeting in April 2004, to designate KAERI as the coordinating organization for a work package on the 'Web-based Exchange of Information and Material for Nuclear Education and Training'. The committee also identified four more work packages and the respective coordinators at the same meeting. To implement the task of the web-based exchange, a website (www.anent-tepm.org) was designed with three functional objectives. The first function was to provide the ANENT member websites with a comprehensive connection with each other as well as to other sites relevant to nuclear education and training. The second one was to provide the collected information and materials. The last one was to provide a systematic and sustainable means to add, revise, and share the information and materials of high quality. As a result, the web site has been structured to deal with the overall information about ANENT, group activities (e.g. Coordination Committee meetings and work packages), inter-organization (or network) link, thematic information/materials database (or link), and the management of human resources. The ANENT website has been temporarily operated and is being revised to fulfil the objectives and reach a consensus among the ANENT members. In parallel, a set of information about education and training courses and teaching materials available from the network members is being collected, which

Elliott, B; Elliott, G

2000-01-01

In 1998, 22 million individuals reported surfing the web for medical information, and this number will increase to over 30 million by 2000. Fifteen of the highest volume medical web sites are described in this paper. Sponsorship and/or ownership of the fifteen sites varied. The government sponsors one, and some are the products of well-known educational institutions. One site is supported by a consumer health organization, and the American Medical Association was in the top 15. However, the most common owners are commercial, for-profit businesses. Attributes of the ideal site were categorized, and include a robust privacy and disclosure statement with an emphasis on education and an appropriate role for advertising. The covering of Complementary and Alternative Medicine (CAM) should be in a balanced and unbiased manner. There has to be an emphasis on knowledge based evidence as opposed to testimonials, and sources should be timely and reviewed. Bibliographies of authors need to be available. Hyperlinking to other web resources is valuable, as even the largest of sites cannot come close to covering all of medicine.

A design method for an intuitive web site

Energy Technology Data Exchange (ETDEWEB)

Quinniey, M.L.; Diegert, K.V.; Baca, B.G.; Forsythe, J.C.; Grose, E.

1999-11-03

The paper describes a methodology for designing a web site for human factor engineers that is applicable for designing a web site for a group of people. Many web pages on the World Wide Web are not organized in a format that allows a user to efficiently find information. Often the information and hypertext links on web pages are not organized into intuitive groups. Intuition implies that a person is able to use their knowledge of a paradigm to solve a problem. Intuitive groups are categories that allow web page users to find information by using their intuition or mental models of categories. In order to improve the human factors engineers efficiency for finding information on the World Wide Web, research was performed to develop a web site that serves as a tool for finding information effectively. The paper describes a methodology for designing a web site for a group of people who perform similar task in an organization.

Program Director as Webmaster? Analysis of 131 Anesthesiology Department Web Sites and Program Director Web Site Involvement and Opinion Survey.

Science.gov (United States)

Daneshpayeh, Negin; Lee, Howard; Berger, Jeffrey

2013-01-01

The last formal review of academic anesthesiology department Web sites (ADWs) for content was conducted in 2009. ADWs have been rated as very important by medical students in researching residency training programs; however, the rapid evolution of sites require that descriptive statistics must be more current to be considered reliable. We set out to provide an updated overview of ADW content and to better understand residency program directors' (PD) role and comfort with ADWs. Two independent reviewers (ND and HL) analyzed all 131 Accreditation Council for Graduate Medical Education (ACGME) accredited ADWs. A binary system (Yes/No) was used to determine which features were present. Reviewer reliability was confirmed with inter-rater reliability and percentage agreement calculation. Additionally, a blinded electronic survey (Survey Monkey, Portland, OR) was sent to anesthesiology residency PDs via electronic mail investigating the audiences for ADWs, the frequency of updates and the degree of PD involvement. 13% of anesthesiology departments still lack a Web site with a homepage with links to the residency program and educational offerings (18% in 2009). Only half (55%) of Web sites contain information for medical students, including clerkship information. Furthermore, programs rarely contain up-to-date calendars (13%), accreditation cycle lengths (11%), accreditation dates (7%) or board pass rates (6%). The PD survey, completed by 42 of 131 PDs, noted a correlation (r = 0.36) between the number of years as PD and the frequency of Web site updates - less experienced PDs appear to update their sites more frequently (p = 0.03). Although 86% of PDs regarded a Web site as "very" important in recruitment, only 9% felt "very" comfortable with the skills required to advertise and market a Web site. Despite the overall increase in ADW content since 2009, privacy concerns, limited resources and time constraints may prevent PDs from providing the most up-to-date Web sites for

Ustjanauskas, A E; Harris, J L; Schwartz, M B

2014-10-01

Food marketing contributes to childhood obesity. Food companies commonly place display advertising on children's web sites, but few studies have investigated this form of advertising. Document the number of food and beverage display advertisements viewed on popular children's web sites, nutritional quality of advertised brands and proportion of advertising approved by food companies as healthier dietary choices for child-directed advertising. Syndicated Internet exposure data identified popular children's web sites and food advertisements viewed on these web sites from July 2009 through June 2010. Advertisements were classified according to food category and companies' participation in food industry self-regulation. The percent of advertisements meeting government-proposed nutrition standards was calculated. 3.4 billion food advertisements appeared on popular children's web sites; 83% on just four web sites. Breakfast cereals and fast food were advertised most often (64% of ads). Most ads (74%) promoted brands approved by companies for child-directed advertising, but 84% advertised products that were high in fat, sugar and/or sodium. Ads for foods designated by companies as healthier dietary choices appropriate for child-directed advertising were least likely to meet independent nutrition standards. Most foods advertised on popular children's web sites do not meet independent nutrition standards. Further improvements to industry self-regulation are required. © 2013 The Authors.

Usability Evaluation of Public Web Mapping Sites

Science.gov (United States)

Wang, C.

2014-04-01

Web mapping sites are interactive maps that are accessed via Webpages. With the rapid development of Internet and Geographic Information System (GIS) field, public web mapping sites are not foreign to people. Nowadays, people use these web mapping sites for various reasons, in that increasing maps and related map services of web mapping sites are freely available for end users. Thus, increased users of web mapping sites led to more usability studies. Usability Engineering (UE), for instance, is an approach for analyzing and improving the usability of websites through examining and evaluating an interface. In this research, UE method was employed to explore usability problems of four public web mapping sites, analyze the problems quantitatively and provide guidelines for future design based on the test results. Firstly, the development progress for usability studies were described, and simultaneously several usability evaluation methods such as Usability Engineering (UE), User-Centered Design (UCD) and Human-Computer Interaction (HCI) were generally introduced. Then the method and procedure of experiments for the usability test were presented in detail. In this usability evaluation experiment, four public web mapping sites (Google Maps, Bing maps, Mapquest, Yahoo Maps) were chosen as the testing websites. And 42 people, who having different GIS skills (test users or experts), gender (male or female), age and nationality, participated in this test to complete the several test tasks in different teams. The test comprised three parts: a pretest background information questionnaire, several test tasks for quantitative statistics and progress analysis, and a posttest questionnaire. The pretest and posttest questionnaires focused on gaining the verbal explanation of their actions qualitatively. And the design for test tasks targeted at gathering quantitative data for the errors and problems of the websites. Then, the results mainly from the test part were analyzed. The

Social networking sites and older users - a systematic review.

Nef, Tobias; Ganea, Raluca L; Müri, René M; Mosimann, Urs P

2013-07-01

Social networking sites can be beneficial for senior citizens to promote social participation and to enhance intergenerational communication. Particularly for older adults with impaired mobility, social networking sites can help them to connect with family members and other active social networking users. The aim of this systematic review is to give an overview of existing scientific literature on social networking in older users. Computerized databases were searched and 105 articles were identified and screened using exclusion criteria. After exclusion of 87 articles, 18 articles were included, reviewed, classified, and the key findings were extracted. Common findings are identified and critically discussed and possible future research directions are outlined. The main benefit of using social networking sites for older adults is to enter in an intergenerational communication with younger family members (children and grandchildren) that is appreciated by both sides. Identified barriers are privacy concerns, technical difficulties and the fact that current Web design does not take the needs of older users into account. Under the conditions that these problems are carefully addressed, social networking sites have the potential to support today's and tomorrow's communication between older and younger family members.

Kinzie, Mable B.; Cohn, Wendy F.; Julian, Marti F.; Knaus, William A.

2002-01-01

As the Internet continues to grow as a delivery medium for health information, the design of effective Web sites becomes increasingly important. In this paper, the authors provide an overview of one effective model for Web site design, a user-centered process that includes techniques for needs assessment, goal/task analysis, user interface design, and rapid prototyping. They detail how this approach was employed to design a family health history Web site, Health Heritage . This Web site helps patients record and maintain their family health histories in a secure, confidential manner. It also supports primary care physicians through analysis of health histories, identification of potential risks, and provision of health care recommendations. Visual examples of the design process are provided to show how the use of this model resulted in an easy-to-use Web site that is likely to meet user needs. The model is effective across diverse content arenas and is appropriate for applications in varied media. PMID:12087113

Full Text Available As the Internet evolved, social networks (such as Facebook have bloomed and brought together an astonishing number of users. Mashing up mobile phones and sensors with these social environments enables the creation of people-centric sensing systems which have great potential for expanding our current social networking usage. However, such systems also have many associated technical challenges, such as privacy concerns, activity detection mechanisms or intermittent connectivity, as well as limitations due to the heterogeneity of sensor nodes and networks. Considering the openness of the Web 2.0, good technical solutions for these cases consist of frameworks that expose sensing data and functionalities as common Web-Services. This paper presents our RESTful Web Service-based model for people-centric sensing frameworks, which uses sensors and mobile phones to detect users’ activities and locations, sharing this information amongst the user’s friends within a social networking site. We also present some screenshot results of our experimental prototype.

2003-07-10

The BABAR Web site was established in 1993 at the Stanford Linear Accelerator Center (SLAC) to support the BABAR experiment, to report its results, and to facilitate communication among its scientific and engineering collaborators, currently numbering about 600 individuals from 75 collaborating institutions in 10 countries. The BABAR Web site is, therefore, a community Web site. At the same time it is hosted at SLAC and funded by agencies that demand adherence to policies decided under different priorities. Additionally, the BABAR Web administrators deal with the problems that arise during the course of managing users, content, policies, standards, and changing technologies. Desired solutions to some of these problems may be incompatible with the overall administration of the SLAC Web sites and/or the SLAC policies and concerns. There are thus different perspectives of the same Web site and differing expectations in segments of the SLAC population which act as constraints and challenges in any review or re-engineering activities. Web Engineering, which post-dates the BABAR Web, has aimed to provide a comprehensive understanding of all aspects of Web development. This paper reports on the first part of a recent review of application of Web Engineering methods to the BABAR Web site, which has led to explicit user and information models of the BABAR community and how SLAC and the BABAR community relate and react to each other. The paper identifies the issues of a community Web site in a hierarchical, semi-governmental sector and formulates a strategy for periodic reviews of BABAR and similar sites. A separate paper reports on the findings of a user survey and selected interviews with users, along with their implications and recommendations for future.

Food marketing on popular children's web sites: a content analysis.

Science.gov (United States)

Alvy, Lisa M; Calvert, Sandra L

2008-04-01

In 2006 the Institute of Medicine (IOM) concluded that food marketing was a contributor to childhood obesity in the United States. One recommendation of the IOM committee was for research on newer marketing venues, such as Internet Web sites. The purpose of this cross-sectional study was to answer the IOM's call by examining food marketing on popular children's Web sites. Ten Web sites were selected based on market research conducted by KidSay, which identified favorite sites of children aged 8 to 11 years during February 2005. Using a standardized coding form, these sites were examined page by page for the existence, type, and features of food marketing. Web sites were compared using chi2 analyses. Although food marketing was not pervasive on the majority of the sites, seven of the 10 Web sites contained food marketing. The products marketed were primarily candy, cereal, quick serve restaurants, and snacks. Candystand.com, a food product site, contained a significantly greater amount of food marketing than the other popular children's Web sites. Because the foods marketed to children are not consistent with a healthful diet, nutrition professionals should consider joining advocacy groups to pressure industry to reduce online food marketing directed at youth.

[Web-ring of sites for pathologists in the internet: a computer-mediated communication environment].

Science.gov (United States)

Khramtsov, A I; Isianov, N N; Khorzhevskiĭ, V A

2009-01-01

The recently developed Web-ring of pathology-related Web-sites has transformed computer-mediated communications for Russian-speaking pathologists. Though the pathologists may be geographically dispersed, the network provides a complex of asynchronous and synchronous conferences for the purposes of diagnosis, consultations, education, communication, and collaboration in the field of pathology. This paper describes approaches to be used by participants of the pathology-related Web-ring. The approaches are analogous to the tools employed in telepathology and digital microscopy. One of the novel methodologies is the use of Web-based conferencing systems, in which the whole slide digital images of tissue microarrays were jointly reviewed online by pathologists at distant locations. By using ImageScope (Aperio Technologies) and WebEx connect desktop management technology, they shared presentations and images and communicated in realtime. In this manner, the Web-based forums and conferences will be a powerful addition to a telepathology.

The effects of Web site structure: the role of personal difference.

Science.gov (United States)

Chung, Hwiman; Ahn, Euijin

2007-12-01

This study examined the effects of Web site structures in terms of advertising effectiveness- memory, attitude, and behavioral intentions. The primary research question for this study is, What type of Web site (Web ad) structure is most effective? In the pilot study, we tested the difference between two Web site structures, linear and interactive, in terms of traditional advertising effectiveness. Results from the pilot study did not support our research expectations. However, differences in terms of memory were noted between the two structures. After re-creating the Web site based on subjects' comments, in the final experiment, we examined the differences between the two structures and the moderating role of personality difference on the effects of Web site structure. The results confirm that participants' attitude, memory, and behavioral intentions were affected differently by the different Web site structures. However, some research hypotheses were not supported by the current data.

Digital libraries and World Wide Web sites and page persistence.

Directory of Open Access Journals (Sweden)

Wallace Koehler

1999-01-01

Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some

GASS-WEB: a web server for identifying enzyme active sites based on genetic algorithms.

Enzyme active sites are important and conserved functional regions of proteins whose identification can be an invaluable step toward protein function prediction. Most of the existing methods for this task are based on active site similarity and present limitations including performing only exact matches on template residues, template size restraints, despite not being capable of finding inter-domain active sites. To fill this gap, we proposed GASS-WEB, a user-friendly web server that uses GASS (Genetic Active Site Search), a method based on an evolutionary algorithm to search for similar active sites in proteins. GASS-WEB can be used under two different scenarios: (i) given a protein of interest, to match a set of specific active site templates; or (ii) given an active site template, looking for it in a database of protein structures. The method has shown to be very effective on a range of experiments and was able to correctly identify >90% of the catalogued active sites from the Catalytic Site Atlas. It also managed to achieve a Matthew correlation coefficient of 0.63 using the Critical Assessment of protein Structure Prediction (CASP 10) dataset. In our analysis, GASS was ranking fourth among 18 methods. GASS-WEB is freely available at http://gass.unifei.edu.br/. © The Author(s) 2017.

Web vulnerability study of online pharmacy sites.

Science.gov (United States)

Kuzma, Joanne

2011-01-01

Consumers are increasingly using online pharmacies, but these sites may not provide an adequate level of security with the consumers' personal data. There is a gap in this research addressing the problems of security vulnerabilities in this industry. The objective is to identify the level of web application security vulnerabilities in online pharmacies and the common types of flaws, thus expanding on prior studies. Technical, managerial and legal recommendations on how to mitigate security issues are presented. The proposed four-step method first consists of choosing an online testing tool. The next steps involve choosing a list of 60 online pharmacy sites to test, and then running the software analysis to compile a list of flaws. Finally, an in-depth analysis is performed on the types of web application vulnerabilities. The majority of sites had serious vulnerabilities, with the majority of flaws being cross-site scripting or old versions of software that have not been updated. A method is proposed for the securing of web pharmacy sites, using a multi-phased approach of technical and managerial techniques together with a thorough understanding of national legal requirements for securing systems.

Improving web site performance using commercially available analytical tools.

Science.gov (United States)

Ogle, James A

2010-10-01

It is easy to accurately measure web site usage and to quantify key parameters such as page views, site visits, and more complex variables using commercially available tools that analyze web site log files and search engine use. This information can be used strategically to guide the design or redesign of a web site (templates, look-and-feel, and navigation infrastructure) to improve overall usability. The data can also be used tactically to assess the popularity and use of new pages and modules that are added and to rectify problems that surface. This paper describes software tools used to: (1) inventory search terms that lead to available content; (2) propose synonyms for commonly used search terms; (3) evaluate the effectiveness of calls to action; (4) conduct path analyses to targeted content. The American Academy of Orthopaedic Surgeons (AAOS) uses SurfRay's Behavior Tracking software (Santa Clara CA, USA, and Copenhagen, Denmark) to capture and archive the search terms that have been entered into the site's Google Mini search engine. The AAOS also uses Unica's NetInsight program to analyze its web site log files. These tools provide the AAOS with information that quantifies how well its web sites are operating and insights for making improvements to them. Although it is easy to quantify many aspects of an association's web presence, it also takes human involvement to analyze the results and then recommend changes. Without a dedicated resource to do this, the work often is accomplished only sporadically and on an ad hoc basis.

Francomano, Jesse A; Harpin, Scott B

2015-01-01

Social networking site use has exploded among youth in the last few years and is being adapted as an important tool for healthcare interventions and serving as a platform for adolescents to gain access to health information. The aim of this study was to examine the strengths, weaknesses, and best practices of utilizing Facebook in adolescent health promotion and research via pragmatic literature review. We also examine how sites can facilitate ethically sound healthcare for adolescents, particularly at-risk youth. We conducted a literature review of health and social sciences literature from the past 5 years related to adolescent health and social network site use. Publications were grouped by shared content then categorized by themes. Five themes emerged: access to healthcare information, peer support and networking, risk and benefits of social network site use in care delivery, overcoming technological barriers, and social network site interventions. More research is needed to better understand how such Web sites can be better utilized to provide access to adolescents seeking healthcare. Given the broad reach of social network sites, all health information must be closely monitored for accurate, safe distribution. Finally, consent and privacy issues are omnipresent in social network sites, which calls for standards of ethical use.

Marcus, Bernd; Machilek, Franz; Schütz, Astrid

2006-06-01

This research examined the personality of owners of personal Web sites based on self-reports, visitors' ratings, and the content of the Web sites. The authors compared a large sample of Web site owners with population-wide samples on the Big Five dimensions of personality. Controlling for demographic differences, the average Web site owner reported being slightly less extraverted and more open to experience. Compared with various other samples, Web site owners did not generally differ on narcissism, self-monitoring, or self-esteem, but gender differences on these traits were often smaller in Web site owners. Self-other agreement was highest with Openness to Experience, but valid judgments of all Big Five dimensions were derived from Web sites providing rich information. Visitors made use of quantifiable features of the Web site to infer personality, and the cues they utilized partly corresponded to self-reported traits. Copyright 2006 APA, all rights reserved.

Patients can access laboratory results using various technologies. The aim of this study was to integrate the laboratory results into the hospital Web site based on patients' viewpoints and priorities and to measure patients' satisfaction. This descriptive-analytical study was conducted in 2015. First, a questionnaire was distributed among 200 patients to assess patients' priorities to receive laboratory results through the Web site. Second, those who agreed (n = 95) to receive their laboratory results through the Web site were identified. Then, the required changes were made to the hospital Web site based on patients' viewpoints and priorities. Third, patients were divided into two groups. The first group received their laboratory results through the Web site on the date had been announced during their visit to the laboratory. The second group was informed by SMS once their results were shown on the Web site. After receiving laboratory results, patients' satisfaction was evaluated. More than half of the participants (n = 53, 55.8%) were highly satisfied with receiving the results electronically. The higher number of people in SMS group (n = 9, 20.9%) reported that they were satisfied with time-saving compared to other group (n = 2, 3.8%) (P = .04).

Designing Industrial Networks Using Ecological Food Web Metrics.

Layton, Astrid; Bras, Bert; Weissburg, Marc

2016-10-18

Biologically Inspired Design (biomimicry) and Industrial Ecology both look to natural systems to enhance the sustainability and performance of engineered products, systems and industries. Bioinspired design (BID) traditionally has focused on a unit operation and single product level. In contrast, this paper describes how principles of network organization derived from analysis of ecosystem properties can be applied to industrial system networks. Specifically, this paper examines the applicability of particular food web matrix properties as design rules for economically and biologically sustainable industrial networks, using an optimization model developed for a carpet recycling network. Carpet recycling network designs based on traditional cost and emissions based optimization are compared to designs obtained using optimizations based solely on ecological food web metrics. The analysis suggests that networks optimized using food web metrics also were superior from a traditional cost and emissions perspective; correlations between optimization using ecological metrics and traditional optimization ranged generally from 0.70 to 0.96, with flow-based metrics being superior to structural parameters. Four structural food parameters provided correlations nearly the same as that obtained using all structural parameters, but individual structural parameters provided much less satisfactory correlations. The analysis indicates that bioinspired design principles from ecosystems can lead to both environmentally and economically sustainable industrial resource networks, and represent guidelines for designing sustainable industry networks.

2012-02-01

The Internet is a vast information resource for both patients and healthcare professionals. However, the quality and content often lack formal scrutiny, so we examined the quality of patient information regarding tinnitus on the Internet. Using the three most popular search engines (google.com, yahoo.com, and msn.com), we found pertinent Web sites using the search term tinnitus. Web sites\\' accountability and authorship were evaluated using previously published criteria. The quality of patient information about tinnitus was assessed using a new 10-point scale, the Tinnitus Information Value (TIV). Statistical analysis was performed using the independent sample t-test (p Web sites was constructed using the first 30 English-language Web sites identified by each search engine. After duplicates and sites only containing links to other Web sites were eliminated, 39 remained. The mean score for accountability was 2.13 on scale of 0 to 7. The mean TIV was 5.0 on a scale of 0 to 10. Only 12 sites (30.8%) had their authors clearly identified. Twenty-two (56.4%) sites were sponsored by commercial interests or represented private practices. The mean TIV was significantly higher (p = 0.037) for noncommercial (personal, academic institution, or charity) sites (5.88 +\\/- 2.39 SD) than those representing commercial interests (4.32 +\\/- 2.10 SD). Tinnitus information available on the Internet is indeed variable, and care should be taken in recommending tinnitus Web sites to patients.

Graber, Mark A; D'Alessandro, Donna M; Johnson-West, Jill

2002-07-01

Most individuals would like to maintain the privacy of their medical information on the World Wide Web (WWW). In response, commercial interests and other sites post privacy policies that are designed to inform users of how their information will be used. However, it is not known if these statements are comprehensible to most WWW users. The purpose of this study was to determine the reading level of privacy statements on Internet health Web sites and to determine whether these statements can inform users of their rights. This was a descriptive study. Eighty Internet health sites were examined and the readability of their privacy policies was determined. The selected sample included the top 25 Internet health sites as well as other sites that a user might encounter while researching a common problem such as high blood pressure. Sixty percent of the sites were commercial (.com), 17.5% were organizations (.org), 8.8% were from the United Kingdom (.uk), 3.8% were United States governmental (.gov), and 2.5% were educational (.edu). The readability level of the privacy policies was calculated using the Flesch, the Fry, and the SMOG readability levels. Of the 80 Internet health Web sites studied, 30% (including 23% of the commercial Web sites) had no privacy policy posted. The average readability level of the remaining sites required 2 years of college level education to comprehend, and no Web site had a privacy policy that was comprehensible by most English-speaking individuals in the United States. The privacy policies of health Web sites are not easily understood by most individuals in the United States and do not serve to inform users of their rights. Possible remedies include rewriting policies to make them comprehensible and protecting online health information by using legal statutes or standardized insignias indicating compliance with a set of privacy standards (eg, "Health on the Net" [HON] http://www.hon.ch).

Prescription drug brand Web sites: Guidance where none exists

Directory of Open Access Journals (Sweden)

Lewis Glinert, Ph.D

2010-01-01

Full Text Available This paper applies insights from linguistics and discourse analysis to prescription drug brand Web sites, with special reference to the 100 top-selling drugs. Such sites give the outward appearance of being a place to go for straightforward information about a specific brand. In reality, they present a confused mix of brand information, health information and hype, muddled organization, and poor indication of authority, creating an imbalance between benefit and risk content. In so doing, they breach the letter and spirit of the regulations governing direct-to-consumer advertising, which the FDA has by default applied to such Web sites but which were not designed for this special type of discourse. The many communicative difficulties proven to be caused by Web sites in general, in particular for the elderly and less literate, also pose ethical problems. A rethinking of the verbal and visual design of these drug sites is needed -- and new regulatory guidance, for which this paper offers recommendations. At stake is not just the quality of health information at brand drug sites but also their credibility.

Full Text Available The most powerful marketing, service, and information-distribution tool a library has today is its Web site, but providing Web content in many languages is complex. Before allocating scarce technical and financial resources, it is valuable to learn about writing systems, types of writing, how computers render and represent writing systems, and to study potential problem areas and their possible solutions. The accepted Web standard for presenting languages is Unicode and a full understanding of its history and the coding tools it provides is essential to making appropriate decisions for specific multilingual and internationalization projects. Actual coding examples, as well as a sampling of existing multilingual library services, also serve to illuminate the path of implementation.

To map and investigate the relationships established on the web between leading health-research institutions around the world. Sample selection was based on the World Health Organization (WHO) Collaborating Centres (CCs). Data on the 768 active CCs in 89 countries were retrieved from the WHO's database. The final sample consisted of 190 institutions devoted to health sciences in 42 countries. Data on each institution's website were retrieved using webometric techniques (interlinking), and an asymmetric matrix was generated for social network analysis. The results showed that American and European institutions, such as the Centers for Disease Control and Prevention (CDC), the National Institutes of Health (NIH) and the National Institute of Health and Medical Research (INSERM), are the most highly connected on the web and have a higher capacity to attract hyperlinks. The Karolinska Institute (KI-SE) in Sweden is well placed as an articulation point between several integrants of the network and the component's core but lacks general recognition on the web by hyperlinks. Regarding the north-south divide, Mexico and Brazil appear to be key southern players on the web. The results showed that the hyperlinks exchanged between northern and southern countries present an abysmal gap: 99.49% of the hyperlinks provided by the North are directed toward the North itself, in contrast to 0.51% that are directed toward the South. Regarding the South, its institutions are more connected to its northern partners, with 98.46% of its hyperlinks directed toward the North, and mainly toward the United States, compared with 1.54% toward southern neighbors. It is advisable to strengthen integration policies on the web and to increase web networking through hyperlink exchange. In this way, the web could actually reflect international cooperation in health and help to legitimize and enhance the visibility of the many existing south-south collaboration networks.

Young, Bradley L; Cantrell, Colin K; Patt, Joshua C; Ponce, Brent A

2018-06-01

Accessible, adequate online information is important to fellowship applicants. Program web sites can affect which programs applicants apply to, subsequently altering interview costs incurred by both parties and ultimately impacting rank lists. Web site analyses have been performed for all orthopaedic subspecialties other than those involved in the combined adult reconstruction and musculoskeletal (MSK) oncology fellowship match. A complete list of active programs was obtained from the official adult reconstruction and MSK oncology society web sites. Web site accessibility was assessed using a structured Google search. Accessible web sites were evaluated based on 21 previously reported content criteria. Seventy-four adult reconstruction programs and 11 MSK oncology programs were listed on the official society web sites. Web sites were identified and accessible for 58 (78%) adult reconstruction and 9 (82%) MSK oncology fellowship programs. No web site contained all content criteria and more than half of both adult reconstruction and MSK oncology web sites failed to include 12 of the 21 criteria. Several programs participating in the combined Adult Reconstructive Hip and Knee/Musculoskeletal Oncology Fellowship Match did not have accessible web sites. Of the web sites that were accessible, none contained comprehensive information and the majority lacked information that has been previously identified as being important to perspective applicants.

Regional networking between services that provide mental health care in Brazil's decentralized public health system is challenging, partly due to the simultaneous existence of services managed by municipal and state authorities and a lack of efficient and transparent mechanisms for continuous and updated communication between them. Since 2011, the Ribeirao Preto Medical School and the XIII Regional Health Department of the Sao Paulo state, Brazil, have been developing and implementing a web-based information system to facilitate an integrated care throughout a public regional mental health care network. After a profound on-site analysis, the structure of the network was identified and a web-based information system for psychiatric admissions and discharges was developed and implemented using a socio-technical approach. An information technology team liaised with mental health professionals, health-service managers, municipal and state health secretariats and judicial authorities. Primary care, specialized community services, general emergency and psychiatric wards services, that comprise the regional mental healthcare network, were identified and the system flow was delineated. The web-based system overcame the fragmentation of the healthcare system and addressed service specific needs, enabling: detailed patient information sharing; active coordination of the processes of psychiatric admissions and discharges; real-time monitoring; the patients' status reports; the evaluation of the performance of each service and the whole network. During a 2-year period of operation, it registered 137 services, 480 health care professionals and 4271 patients, with a mean number of 2835 accesses per month. To date the system is successfully operating and further expanding. We have successfully developed and implemented an acceptable, useful and transparent web-based information system for a regional mental healthcare service network in a medium-income country with a decentralized

Prescription drug brand Web sites: Guidance where none exists

Directory of Open Access Journals (Sweden)

Lewis Glinert

2010-06-01

Full Text Available This paper applies insights from linguistics and discourse analysis to prescription drug brand Web sites, with special reference to the 100 top-selling drugs. Such sites give the outward appearance of being a place to go for straightforward information about a specific brand. In reality, they present a confused mix of brand information, health information and hype, muddled organization, and poor indication of authority, creating an imbalance between benefit and risk content. In so doing, they breach the letter and spirit of the regulations governing direct-to-consumer advertising, which the FDA has by default applied to such Web sites but which were not designed for this special type of discourse. The many communicative difficulties proven to be caused by Web sites in general, in particular for the elderly and less literate, also pose ethical problems. A rethinking of the verbal and visual design of these drug sites is needed -- and new regulatory guidance, for which this paper offers recommendations. At stake is not just the quality of health information at brand drug sites but also their credibility. Type: Original Research

Direct-to-consumer advertising via the Internet: the role of Web site design.

Science.gov (United States)

Sewak, Saurabh S; Wilkin, Noel E; Bentley, John P; Smith, Mickey C

2005-06-01

Recent attempts to propose criteria for judging the quality of pharmaceutical and healthcare Web sites do not distinguish between attributes of Web site design related to content and other attributes not related to the content. The Elaboration Likelihood Model from persuasion literature is used as a framework for investigating the effects of Web site design on consequents like attitude and knowledge acquisition. A between-subjects, 2 (high or low involvement)x2 (Web site designed with high or low aspects of visual appeal) factorial design was used in this research. College students were randomly assigned to these treatment groups yielding a balanced design with 29 observations per treatment cell. Analysis of variance results for the effects of involvement and Web site design on attitude and knowledge indicated that the interaction between the independent variables was not significant in both analyses. Examination of main effects revealed that participants who viewed the Web site with higher visual appeal actually had slightly lower knowledge scores (6.32) than those who viewed the Web site with lower visual appeal (7.03, F(1,112)=3.827, P=.053). Results of this research seem to indicate that aspects of Web site design (namely aspects of visual appeal and quality) may not play a role in attaining desired promotional objectives, which can include development of favorable attitudes toward the product and facilitating knowledge acquisition.

Doshi, Amol; Patrick, Kevin; Sallis, James F; Calfas, Karen

2003-01-01

Physical activity (PA) Web sites were assessed for their use of behavior change theories, including constructs of the health belief model, Transtheoretical Model, social cognitive theory, and the theory of reasoned action and planned behavior. An evaluation template for assessing PA Web sites was developed, and content validity and interrater reliability were demonstrated. Two independent raters evaluated 24 PA Web sites. Web sites varied widely in application of theory-based constructs, ranging from 5 to 48 on a 100-point scale. The most common intervention strategies were general information, social support, and realistic goal areas. Coverage of theory-based strategies was low, varying from 26% for social cognitive theory to 39% for health belief model. Overall, PA Web sites provided little assessment, feedback, or individually tailored assistance for users. They were unable to substantially tailor the on-line experience for users at different stages of change or different demographic characteristics.

Optometry and ophthalmology: the Internet connection--assessing consumer health web sites.

Science.gov (United States)

Soroka, M; Schachne, E; Saludes, I

2001-11-01

The Internet is a major conduit of health information. Consumers frequently rely on it without verifying its validity. The purpose of this study was to assess the accuracy and currency of Internet-based information on the roles and practice of optometrists, which has been found to be misleading, inaccurate, and often outdated. Using search engines and ranking directories, 16 popular health Web sites were examined for differentiation between optometry and ophthalmology. Each site's eye care content was reviewed for syndication, definitions, provider directories, linkages to eye organizations, and provider recommendations in treatment of certain conditions. Many Web sites use a syndicated source for their health content and several use Merriam-Webster as their primary dictionary. A majority of sites provided poor definitions for optometry. Most Web sites were biased in recommending ophthalmologists and do not include optometrists as licensed providers in treatment of certain eye diseases. For example, Intelihealth, Aetnaushc, and Noah-Health recommend only ophthalmologists for the treatment of conjunctivitis. Inaccuracies and misleading information about optometry do exist and undermine the role of optometrists in delivery of eye care. When alerted, several Web sites were receptive to proposed changes. While some efforts have been undertaken to monitor Web sites, the profession must develop a concrete effort to ensure that it is correctly represented on the Internet.

Guidelines for medical and health information sites on the internet: principles governing AMA web sites. American Medical Association.

Science.gov (United States)

Winker, M A; Flanagin, A; Chi-Lum, B; White, J; Andrews, K; Kennett, R L; DeAngelis, C D; Musacchio, R A

Access to medical information via the Internet has the potential to speed the transformation of the patient-physician relationship from that of physician authority ministering advice and treatment to that of shared decision making between patient and physician. However, barriers impeding this transformation include wide variations in quality of content on the Web, potential for commercial interests to influence online content, and uncertain preservation of personal privacy. To address these issues, the American Medical Association (AMA) has developed principles to guide development and posting of Web site content, govern acquisition and posting of online advertising and sponsorship, ensure site visitors' and patients' rights to privacy and confidentiality, and provide effective and secure means of e-commerce. While these guidelines were developed for the AMA Web sites and visitors to these sites, they also may be useful to other providers and users of medical information on the Web. These principles have been developed with the understanding that they will require frequent revision to keep pace with evolving technology and practices on the Internet. The AMA encourages review and feedback from readers, Web site visitors, policymakers, and all others interested in providing reliable quality information via the Web.

Web Page Classification Method Using Neural Networks

Science.gov (United States)

Selamat, Ali; Omatu, Sigeru; Yanagimoto, Hidekazu; Fujinaka, Toru; Yoshioka, Michifumi

Automatic categorization is the only viable method to deal with the scaling problem of the World Wide Web (WWW). In this paper, we propose a news web page classification method (WPCM). The WPCM uses a neural network with inputs obtained by both the principal components and class profile-based features (CPBF). Each news web page is represented by the term-weighting scheme. As the number of unique words in the collection set is big, the principal component analysis (PCA) has been used to select the most relevant features for the classification. Then the final output of the PCA is combined with the feature vectors from the class-profile which contains the most regular words in each class before feeding them to the neural networks. We have manually selected the most regular words that exist in each class and weighted them using an entropy weighting scheme. The fixed number of regular words from each class will be used as a feature vectors together with the reduced principal components from the PCA. These feature vectors are then used as the input to the neural networks for classification. The experimental evaluation demonstrates that the WPCM method provides acceptable classification accuracy with the sports news datasets.

The dashboard is accessible to users over the Hanford Local Area Network (HLAN) and provides a highly visual and straightforward status to management on the ideas provided, alleviating the need for resource intensive weekly and monthly reviews

Compilation and network analyses of cambrian food webs.

Directory of Open Access Journals (Sweden)

Jennifer A Dunne

2008-04-01

Full Text Available A rich body of empirically grounded theory has developed about food webs--the networks of feeding relationships among species within habitats. However, detailed food-web data and analyses are lacking for ancient ecosystems, largely because of the low resolution of taxa coupled with uncertain and incomplete information about feeding interactions. These impediments appear insurmountable for most fossil assemblages; however, a few assemblages with excellent soft-body preservation across trophic levels are candidates for food-web data compilation and topological analysis. Here we present plausible, detailed food webs for the Chengjiang and Burgess Shale assemblages from the Cambrian Period. Analyses of degree distributions and other structural network properties, including sensitivity analyses of the effects of uncertainty associated with Cambrian diet designations, suggest that these early Paleozoic communities share remarkably similar topology with modern food webs. Observed regularities reflect a systematic dependence of structure on the numbers of taxa and links in a web. Most aspects of Cambrian food-web structure are well-characterized by a simple "niche model," which was developed for modern food webs and takes into account this scale dependence. However, a few aspects of topology differ between the ancient and recent webs: longer path lengths between species and more species in feeding loops in the earlier Chengjiang web, and higher variability in the number of links per species for both Cambrian webs. Our results are relatively insensitive to the exclusion of low-certainty or random links. The many similarities between Cambrian and recent food webs point toward surprisingly strong and enduring constraints on the organization of complex feeding interactions among metazoan species. The few differences could reflect a transition to more strongly integrated and constrained trophic organization within ecosystems following the rapid

Jumping to (fatal) conclusions? An analysis of video film on a social networking web site of recreational jumping from height into water.

Science.gov (United States)

Moran, Kevin

2014-01-01

In high-income countries, death as a consequence of recreational jumping into water from height has not been well investigated partly because it traditionally has been a covert activity within youth culture. An observational study of video recordings posted on the YouTube web site was used to gather data on the nature of jumping activity in New Zealand and Australia. An analytical framework was developed to identify site- participant- social characteristics (10 variables) and online feedback (4 variables). Of the 389 videos recorded in New Zealand (n = 210) and Australia (n = 179), 929 jumpers were observed, and rivers were the most frequently reported site of jumping activity (New Zealand 47%; Australia 35%). One fifth (20%) of the jumps in New Zealand and one third (33%) in Australia were from heights estimated to be more than 12 m. The YouTube website portraying jumps from height were visited almost half a million times (495,686 hits). Ways of reducing recreational jumping risk via targeted education interventions may be best directed at young male adults. Use of social network sites to foster safe behaviours may be an effective way to educate young people of the inherent risks of jumping from height into water.

Prospective analysis of the quality of Spanish health information web sites after 3 years.

2016-12-01

Although the Internet has become an essential source of health information, our study conducted 3 years ago provided evidence of the low quality of Spanish health web sites. The objective of the present study was to evaluate the quality of Spanish health information web sites now, and to compare these results with those obtained 3 years ago. For the original study, the most visited health information web sites were selected through the PageRank® (Google®) system. The present study evaluated the quality of the same web sites from February to May 2013, using the method developed by Bermúdez-Tamayo et al. and HONCode® criteria. The mean quality of the selected web sites was low and has deteriorated since the previous evaluation, especially in regional health services and institutions' web sites. The quality of private web sites remained broadly similar. Compliance with privacy and update criteria also improved in the intervening period. The results indicate that, even in the case of health web sites, design or appearance is more relevant to developers than quality of information. It is recommended that responsible institutions should increase their efforts to eliminate low-quality health information that may further contribute to health problems.

Krisellen Maloney

2017-09-01

Full Text Available Users' needs and expectations regarding access to information have fundamentally changed, creating a disconnect between how users expect to use a library Web site and how the site was designed. At the same time, library technical infrastructures include legacy systems that were not designedf or the Web environment.

2014-12-01

Access to the medical literature has not kept pace with the mobile revolution. We aimed to (1) gauge interest in a smartphone-optimized Web site for conveniently accessing otolaryngology literature and (2) create an easy-to-access and convenient Web site that displays otolaryngology journal abstracts in a format optimized for smartphones. A survey was sent to physicians of a major US academic otolaryngology-head and neck surgery department. Demographics, literature-browsing habits, and barriers to staying updated were assessed. The response rate was 87%. Ninety-one percent of respondents used a smartphone, and 85% wished they could stay more up to date with the otolaryngology literature. Most respondents believed a convenient smartphone-optimized Web site could help them achieve this goal. A Web site was then developed in collaboration with a university creative department as a proof of concept. The site uses a simple RSS aggregator to display journal abstracts formatted for smartphone-sized screens (www.otosurg.com). © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

2005-12-01

Although large governmental web sites (e.g. USGS, NASA etc.) are important resources, particularly in relation to phenomena with global to regional significance (e.g. recent Tsunami and Hurricane disasters), smaller academic web portals continue to make substantive contributions to web-based learning in the geosciences. The strength of "home-grown" web sites is that they easily can be tailored to specific classes, they often focus on local geologic content, and they potentially integrate classroom, laboratory, and field-based learning in ways that improve introductory classes. Furthermore, innovative multimedia techniques including virtual reality, image manipulations, and interactive streaming video can improve visualization and be particularly helpful for first-time geology students. This poster reports on one such web site, Learning Tools in Earth Science (LTES, http://www.easternct .edu/personal/faculty/hyattj/LTES-v2/), a site developed by geoscience faculty at two state institutions. In contrast to some large web sites with media development teams, LTES geoscientists, with strong support from media and IT service departments, are responsible for geologic content and verification, media development and editing, and web development and authoring. As such, we have considerable control over both content and design of this site. At present the main content modules for LTES include "mineral" and "virtual field trip" links. The mineral module includes an interactive mineral gallery, and a virtual mineral box of 24 unidentified samples that are identical to those used in some of our classes. Students navigate an intuitive web portal to manipulate images and view streaming video segments that explain and undertake standard mineral identification tests. New elements highlighted in our poster include links to a virtual petrographic microscope, in which users can manipulate images to simulate stage rotation in both plane- and cross-polarized light.

The Internet is a common source of information for orthopaedic residents applying for sports medicine fellowships, with the web sites of the American Orthopaedic Society for Sports Medicine (AOSSM) and the San Francisco Match serving as central databases. We sought to evaluate the web sites for accredited orthopaedic sports medicine fellowships with regard to content and accessibility. We reviewed the existing web sites of the ninety-five accredited orthopaedic sports medicine fellowships included in the AOSSM and San Francisco Match databases from February to March 2012. A Google search was performed to determine the overall accessibility of program web sites and to supplement information obtained from the AOSSM and San Francisco Match web sites. The study sample consisted of the eighty-seven programs whose web sites connected to information about the fellowship. Each web site was evaluated for its informational value. Of the ninety-five programs, fifty-one (54%) had links listed in the AOSSM database. Three (3%) of all accredited programs had web sites that were linked directly to information about the fellowship. Eighty-eight (93%) had links listed in the San Francisco Match database; however, only five (5%) had links that connected directly to information about the fellowship. Of the eighty-seven programs analyzed in our study, all eighty-seven web sites (100%) provided a description of the program and seventy-six web sites (87%) included information about the application process. Twenty-one web sites (24%) included a list of current fellows. Fifty-six web sites (64%) described the didactic instruction, seventy (80%) described team coverage responsibilities, forty-seven (54%) included a description of cases routinely performed by fellows, forty-one (47%) described the role of the fellow in seeing patients in the office, eleven (13%) included call responsibilities, and seventeen (20%) described a rotation schedule.

An important step in structure-based drug design consists in the prediction of druggable binding sites. Several algorithms for detecting binding cavities, those likely to bind to a small drug compound, have been developed over the years by clever exploitation of geometric, chemical and evolutionary features of the protein. Here we present a novel knowledge-based approach that uses state-of-the-art convolutional neural networks, where the algorithm is learned by examples. In total, 7622 proteins from the scPDB database of binding sites have been evaluated using both a distance and a volumetric overlap approach. Our machine-learning based method demonstrates superior performance to two other competitive algorithmic strategies. DeepSite is freely available at www.playmolecule.org. Users can submit either a PDB ID or PDB file for pocket detection to our NVIDIA GPU-equipped servers through a WebGL graphical interface. gianni.defabritiis@upf.edu.

Increasing Scalability of Researcher Network Extraction from the Web

Science.gov (United States)

Asada, Yohei; Matsuo, Yutaka; Ishizuka, Mitsuru

Social networks, which describe relations among people or organizations as a network, have recently attracted attention. With the help of a social network, we can analyze the structure of a community and thereby promote efficient communications within it. We investigate the problem of extracting a network of researchers from the Web, to assist efficient cooperation among researchers. Our method uses a search engine to get the cooccurences of names of two researchers and calculates the streangth of the relation between them. Then we label the relation by analyzing the Web pages in which these two names cooccur. Research on social network extraction using search engines as ours, is attracting attention in Japan as well as abroad. However, the former approaches issue too many queries to search engines to extract a large-scale network. In this paper, we propose a method to filter superfluous queries and facilitates the extraction of large-scale networks. By this method we are able to extract a network of around 3000-nodes. Our experimental results show that the proposed method reduces the number of queries significantly while preserving the quality of the network as compared to former methods.

The EarthScope Array Network Facility: application-driven low-latency web-based tools for accessing high-resolution multi-channel waveform data

Science.gov (United States)

Newman, R. L.; Lindquist, K. G.; Clemesha, A.; Vernon, F. L.

2008-12-01

Since April 2004 the EarthScope USArray seismic network has grown to over 400 broadband stations that stream multi-channel data in near real-time to the Array Network Facility in San Diego. Providing secure, yet open, access to real-time and archived data for a broad range of audiences is best served by a series of platform agnostic low-latency web-based applications. We present a framework of tools that interface between the world wide web and Boulder Real Time Technologies Antelope Environmental Monitoring System data acquisition and archival software. These tools provide audiences ranging from network operators and geoscience researchers, to funding agencies and the general public, with comprehensive information about the experiment. This ranges from network-wide to station-specific metadata, state-of-health metrics, event detection rates, archival data and dynamic report generation over a stations two year life span. Leveraging open source web-site development frameworks for both the server side (Perl, Python and PHP) and client-side (Flickr, Google Maps/Earth and jQuery) facilitates the development of a robust extensible architecture that can be tailored on a per-user basis, with rapid prototyping and development that adheres to web-standards.

Web 2.0 Sites for Collaborative Self-Access: The Learning Advisor vs. Google®

Directory of Open Access Journals (Sweden)

Craig D. Howard

2011-09-01

Full Text Available While Web 2.0 technologies provide motivated, self-access learners with unprecedented opportunities for language learning, Web 2.0 designs are not of universally equal value for learning. This article reports on research carried out at Indiana University Bloomington using an empirical method to select websites for self-access language learning. Two questions related to Web 2.0 recommendations were asked: (1 How do recommended Web 2.0 sites rank in terms of interactivity features? (2 How likely is a learner to find highly interactive sites on their own? A list of 20 sites used for supplemental and self-access activities in language programs at five universities was compiled and provided the initial data set. Purposive sampling criteria revealed 10 sites truly represented Web 2.0 design. To address the first question, a feature analysis was applied (Herring, The international handbook of internet research. Berlin: Springer, 2008. An interactivity framework was developed from previous research to identify Web 2.0 design features, and sites were ranked according to feature quantity. The method used to address the second question was an interconnectivity analysis that measured direct and indirect interconnectivity within Google results. Highly interactive Web 2.0 sites were not prominent in Google search results, nor were they often linked via third party sites. It was determined that, using typical keywords or searching via blogs and recommendation sites, self-access learners were highly unlikely to find the most promising Web 2.0 sites for language learning. A discussion of the role of the learning advisor in guiding Web 2.0 collaborative self-access, as well as some strategic short cuts to quick analysis, conclude the article.

2018-05-02

The purpose of this study was to utilize sentiment analysis to describe online opinions toward vaginal mesh. We hypothesized that sentiment in legal Web sites would be more negative than that in medical and reference Web sites. We generated a list of relevant key words related to vaginal mesh and searched Web sites using the Google search engine. Each unique uniform resource locator (URL) was sorted into 1 of 6 categories: "medical", "legal", "news/media", "patient generated", "reference", or "unrelated". Sentiment of relevant Web sites, the primary outcome, was scored on a scale of -1 to +1, and mean sentiment was compared across all categories using 1-way analysis of variance. Tukey test evaluated differences between category pairs. Google searches of 464 unique key words resulted in 11,405 URLs. Sentiment analysis was performed on 8029 relevant URLs (3472 legal, 1625 "medical", 1774 "reference", 666 "news media", 492 "patient generated"). The mean sentiment for all relevant Web sites was +0.01 ± 0.16; analysis of variance revealed significant differences between categories (P Web sites categorized as "legal" and "news/media" had a slightly negative mean sentiment, whereas those categorized as "medical," "reference," and "patient generated" had slightly positive mean sentiments. Tukey test showed differences between all category pairs except the "medical" versus "reference" in comparison with the largest mean difference (-0.13) seen in the "legal" versus "reference" comparison. Web sites related to vaginal mesh have an overall mean neutral sentiment, and Web sites categorized as "medical," "reference," and "patient generated" have significantly higher sentiment scores than related Web sites in "legal" and "news/media" categories.

Translating access into utilization: lessons from the design and evaluation of a health insurance Web site to promote reproductive health care for young women in Massachusetts.

Science.gov (United States)

Janiak, Elizabeth; Rhodes, Elizabeth; Foster, Angel M

2013-12-01

Following state-level health care reform in Massachusetts, young women reported confusion over coverage of contraception and other sexual and reproductive health services under newly available health insurance products. To address this gap, a plain-language Web site titled "My Little Black Book for Sexual Health" was developed by a statewide network of reproductive health stakeholders. The purpose of this evaluation was to assess the health literacy demands and usability of the site among its target audience, women ages 18-26 years. We performed an evaluation of the literacy demands of the Web site's written content and tested the Web site's usability in a health communications laboratory. Participants found the Web site visually appealing and its overall design concept accessible. However, the Web site's literacy demands were high, and all participants encountered problems navigating through the Web site. Following this evaluation, the Web site was modified to be more usable and more comprehensible to women of all health literacy levels. To avail themselves of sexual and reproductive health services newly available under expanded health insurance coverage, young women require customized educational resources that are rigorously evaluated to ensure accessibility. To maximize utilization of reproductive health services under expanded health insurance coverage, US women require customized educational resources commensurate with their literacy skills. The application of established research methods from the field of health communications will enable advocates to evaluate and adapt these resources to best serve their targeted audiences. © 2013.

Cambil-Martín, Jacobo; Flynn, Maria; Villaverde-Gutiérrez, Carmen

2011-09-01

This article presents a study that evaluated the physical accessibility, readability, and usability of Spanish nursing Web sites and discusses the quality assurance issues raised, which are relevant to the wider nursing community. The Internet is recognized as an important source of health information for both nurses and the general public. Although it makes health-related information universally available, the wide variation in the overall quality of health Web sites is problematic. This raises many questions for the nursing profession: about what constitutes a good-quality Web site, about the nature of the information that nurses are finding and using to support their professional education, research, and clinical practice, and about the impact that Internet information ultimately has on health interactions and nursing care. The process of completing this small study showed that it is possible to usefully assess dimensions of Web site quality and suggested that it may be feasible to develop tools to help nurses evaluate national and international nursing Web sites. More research is needed to understand how nurses use the Internet to support their everyday professional practices, but the development and application of international Web site quality assurance tools may be important for maintaining professional nursing standards in the Internet age.

The NIH and Department of Health & Human Services recommend online patient information (OPI) be written at a sixth grade level. We used a panel of readability analyses to assess OPI from NCI-Designated Cancer Center (NCIDCC) Web sites. Cancer.gov was used to identify 68 NCIDCC Web sites from which we collected both general OPI and OPI specific to breast, prostate, lung, and colon cancers. This text was analyzed by 10 commonly used readability tests: the New Dale-Chall Readability Formula, Flesch Reading Ease scale, Flesch-Kinaid Grade Level, FORCAST scale, Fry Readability Graph, Simple Measure of Gobbledygook test, Gunning Frequency of Gobbledygook index, New Fog Count, Raygor Readability Estimate Graph, and Coleman-Liau Index. We tested the hypothesis that the readability of NCIDCC OPI was written at the sixth grade level. Secondary analyses were performed to compare readability of OPI between comprehensive and noncomprehensive centers, by region, and to OPI produced by the American Cancer Society (ACS). A mean of 30,507 words from 40 comprehensive and 18 noncomprehensive NCIDCCs was analyzed (7 nonclinical and 3 without appropriate OPI were excluded). Using a composite grade level score, the mean readability score of 12.46 (ie, college level: 95% CI, 12.13-12.79) was significantly greater than the target grade level of 6 (middle-school: Preadability metrics (P<.05). ACS OPI provides easier language, at the seventh to ninth grade level, across all tests (P<.01). OPI from NCIDCC Web sites is more complex than recommended for the average patient.

2017-06-22

Electronic word-of-mouth on social network sites has been used successfully in marketing. In social marketing, electronic word-of-mouth about products as health behaviors has the potential to be more effective and reach more young adults than health education through traditional mass media. However, little is known about what motivates people to actively initiate electronic word-of-mouth about health behaviors on their personal pages or profiles on social network sites, thus potentially reaching all their contacts on those sites. This study filled the gap by applying a marketing theoretical model to explore the factors associated with electronic word-of-mouth on social network sites about leisure-time physical activity. A Web survey link was sent to undergraduate students at one of the Midwestern universities and 439 of them completed the survey. The average age of the 439 participants was 19 years (SD=1 year, range: 18-24). Results suggested that emotional engagement with leisure-time physical activity (ie, affective involvement in leisure-time physical activity) predicted providing relevant opinions or information on social network sites. Social network site users who perceived stronger ties with all their contacts were more likely to provide and seek leisure-time physical activity opinions and information. People who provided leisure-time physical activity opinions and information were more likely to seek opinions and information, and people who forwarded information about leisure-time physical activity were more likely to chat about it. This study shed light on the application of the electronic word-of-mouth theoretical framework in promoting health behaviors. The findings can also guide the development of future social marketing interventions using social network sites to promote leisure-time physical activity. ©Ni Zhang, Shelly Campo, Jingzhen Yang, Petya Eckler, Linda Snetselaar, Kathleen Janz, Emily Leary.

Wang, Zuoming; Loh, Tracy

2004-01-01

Background Concerns over health information on the Internet have generated efforts to enhance credibility markers; yet how users actually assess the credibility of online health information is largely unknown. Objective This study set out to (1) establish a parsimonious and valid questionnaire instrument to measure credibility of Internet health information by drawing on various previous measures of source, news, and other credibility scales; and (2) to identify the effects of Web-site domains and advertising on credibility perceptions. Methods Respondents (N = 156) examined one of 12 Web-site mock-ups and completed credibility scales in a 3 x 2 x 2 between-subjects experimental design. Factor analysis and validity checks were used for item reduction, and analysis of variance was employed for hypothesis testing of Web-site features' effects. Results In an attempt to construct a credibility instrument, three dimensions of credibility (safety, trustworthiness, and dynamism) were retained, reflecting traditional credibility sub-themes, but composed of items from disparate sources. When testing the effect of the presence or absence of advertising on a Web site on credibility, we found that this depends on the site's domain, with a trend for advertisements having deleterious effects on the credibility of sites with .org domain, but positive effects on sites with .com or .edu domains. Conclusions Health-information Web-site providers should select domains purposefully when they can, especially if they must accept on-site advertising. Credibility perceptions may not be invariant or stable, but rather are sensitive to topic and context. Future research may employ these findings in order to compare other forms of health-information delivery to optimal Web-site features. PMID:15471750

The ProBiS web server is a web server for detection of structurally similar binding sites in the PDB and for local pairwise alignment of protein structures. In this article, we present a new version of the ProBiS web server that is 10 times faster than earlier versions, due to the efficient parallelization of the ProBiS algorithm, which now allows significantly faster comparison of a protein query against the PDB and reduces the calculation time for scanning the entire PDB from hours to minutes. It also features new web services, and an improved user interface. In addition, the new web server is united with the ProBiS-Database and thus provides instant access to pre-calculated protein similarity profiles for over 29 000 non-redundant protein structures. The ProBiS web server is particularly adept at detection of secondary binding sites in proteins. It is freely available at http://probis.cmm.ki.si/old-version, and the new ProBiS web server is at http://probis.cmm.ki.si.

To compare how providers of testosterone replacement therapy (TRT) in large metropolitan cities promote androgen replacement on their patient-oriented Web sites. TRT provider Web sites were identified using Google search and the terms "Testosterone replacement" and the name of the 5 most populous US cities. These Web sites were assessed for (1) type or specialty of medical provider, (2) discussion of the benefits and risks of TRT, and (3) industry affiliations. In total, 75 Web sites were evaluated. Twenty-seven of the 75 clinics (36%) were directed by nonphysicians, 35 (47%) were overseen by nonurology or nonendocrine physicians, and only 13 (17%) were specialist managed. Fourteen of 75 (18.6%) Web sites disclosed industry relationships. Ninety-five percent of Web sites promoted the benefits of TRT including improved sex drive, cognitive improvement, increased muscle strength, and/or improved energy. Only 20 of 75 Web sites (26.6%) described any side effect of TRT. Web sites directed by specialists were twice as likely to discuss risks of TRT compared with nonspecialist providers (41% vs 20%; odds ratio = 2.77; P <.01). Nine of 75 (12%) of all Web sites actually refuted that TRT was associated with significant side effects. Urologists and endocrinologists are in the minority of providers promoting TRT on the Internet. Specialists are more likely to discuss risks associated with TRT although the majority of surveyed Web sites that promote TRT do not mention treatment risks. There is substantial variability in quality and quantity of information on provider Web sites, which may contribute to misinformation regarding this prevalent health issue.

The objective of this study was to find all the existing Web sites of Turkish community pharmacies and evaluate their "quality" in terms of Health on the Net (HON) Code of conduct principles. Multiple Internet search engines were used (google.com, yahoo.com, altavista.com, msn.com). While searching on the Internet, "eczane (pharmacy)" and "eczanesi (pharmacy of)" key words were used. The Internet search lasted for 2 months starting from March 1, 2007 until May 1, 2007. SPSS ver. 11.5 statistical program (SPSS, Inc., Chicago, IL) was used for data entry and analysis. At the end of the Internet search via all the indicated search engines, a total of 203 (all different from each other) community pharmacy Web sites were determined; of these, 14 were under construction and 6 were not accessible. As a result, 183 community pharmacy Web sites were included in the study. All of the Web sites could be accessed (100%). However, the availability of some characteristics of the pharmacies were quite poor. None of the pharmacies met all of the HON principles. Only 11 Web sites were appropriate in terms of complementarity (6.0%). Confidentiality criteria was met by only 14 pharmacies (7.7%). Nine pharmacies (4.9%) completed the "attribution" criteria. Among 183 pharmacy Web sites, the most met HON principle was the "transparency of authorship" (69 pharmacy Web sites; 37.7%). Because of the results of our study, the Turkish Pharmacists Association can take a pioneer role to apply some principles such as HON code of conduct in order to increase the quality of Turkish community pharmacists' Web sites.

Nasution, M. K. M.; Sitompul, O. S.; Noah, S. A.

The Web as a source of information has become part of the social behavior information. Although, by involving only the limitation of information disclosed by search engines in the form of: hit counts, snippets, and URL addresses of web pages, the integrated extraction method produces a social network not only trusted but enriched. Unintegrated extraction methods may produce social networks without explanation, resulting in poor supplemental information, or resulting in a social network of durmise laden, consequently unrepresentative social structures. The integrated superficial method in addition to generating the core social network, also generates an expanded network so as to reach the scope of relation clues, or number of edges computationally almost similar to n(n - 1)/2 for n social actors.

Building a sense of virtual community: the role of the features of social networking sites.

Science.gov (United States)

Chen, Chi-Wen; Lin, Chiun-Sin

2014-07-01

In recent years, social networking sites have received increased attention because of the potential of this medium to transform business by building virtual communities. However, theoretical and empirical studies investigating how specific features of social networking sites contribute to building a sense of virtual community (SOVC)-an important dimension of a successful virtual community-are rare. Furthermore, SOVC scales have been developed, and research on this issue has been called for, but few studies have heeded this call. On the basis of prior literature, this study proposes that perceptions of the three most salient features of social networking sites-system quality (SQ), information quality (IQ), and social information exchange (SIE)-play a key role in fostering SOVC. In particular, SQ is proposed to increase IQ and SIE, and SIE is proposed to enhance IQ, both of which thereafter build SOVC. The research model was examined in the context of Facebook, one of the most popular social networking sites in the world. We adopted Blanchard's scales to measure SOVC. Data gathered using a Web-based questionnaire, and analyzed with partial least squares, were utilized to test the model. The results demonstrate that SIE, SQ, and IQ are the factors that form SOVC. The findings also suggest that SQ plays a fundamental role in supporting SIE and IQ in social networking sites. Implications for theory, practice, and future research directions are discussed.

Social network extraction based on Web: 1. Related superficial methods

Often the nature of something affects methods to resolve the related issues about it. Likewise, methods to extract social networks from the Web, but involve the structured data types differently. This paper reveals several methods of social network extraction from the same sources that is Web: the basic superficial method, the underlying superficial method, the description superficial method, and the related superficial methods. In complexity we derive the inequalities between methods and so are their computations. In this case, we find that different results from the same tools make the difference from the more complex to the simpler: Extraction of social network by involving co-occurrence is more complex than using occurrences.

Using a Web Site to Support a Seismology Course Textbook

Science.gov (United States)

Wysession, M. E.; Stein, S.

2004-12-01

We present a course in seismology that consists of a textbook with an accompanying web site (http://epscx.wustl.edu/seismology/book). The web site serves many different functions, and is of great importance as a companion to the curriculum in several different ways: (1) All of the more than 600 figures from the book are available on the web site. Geophysics is a very visually-oriented discipline, and many concepts are more easily taught with appropriate visual tools. In addition, many instructors are now using computer-based lecture programs such as PowerPoint. To aid in this, all of the figures are displayed in a common JPG format, both with and without titles. They are available to be used in a seismology course, or any kind of Earth Science course. This way, an instructor can easily grab a figure from the web site and drop it into a PowerPoint format. The figures are listed by number, but are also obtainable from menus of thumbnail sketches. If an instructor would like all of the figures, they can be obtained as large zip files, which can be unzipped after downloading. In addition, sample PowerPoint lectures using the figures as well the equations from the text will be available on the course web site. (2) Solutions to all of the homework problems are available in PDF format on the course website. Homework is a vital component of any quantitative course, but it is often a significant time commitment for instructors to derive all of the homework problems. In addition, it is much easier to select which homework problems are desired to be assigned if the solutions can be seen. The 64 pages of homework solutions are on a secure web site that requires a user ID and password that can be obtained from the authors. (3) Any errors found in the textbook are immediately posted on an "Errata" web page. Many of these errors are found by instructors who are using the curriculum (and they are given credit for finding the errors!). The text becomes an interactive process

The Web works in strange ways - unexpected results from MBARI's expanding use of online media and social networking

Science.gov (United States)

Fulton-bennett, K. W.

2011-12-01

As a relatively small organization, the Monterey Bay Aquarium Research Institute has gradually expanded its use of on-line and social media over the past few years. Our web site and expedition blogs have been available for over a decade. In 2009 we established a YouTube channel and RSS feeds. In early 2011 we set up Facebook and Twitter sites that are maintained through automated feeds (e.g. Twitterfeed) as well as by two employees who each spend about two hours a week adding items of interest. Although we do respond to comments, we have not actively encouraged interaction and discussion on our social networking sites, due to limited staff time. Prior to setting up our sites, I studied existing the Facebook pages for a number of marine research institutions and found that the frequency at which a research institution updated its social media site was directly correlated with the number of dedicated followers of that site. For this reason, MBARI set goals for keeping our sites updated on a regular basis-at least monthly for YouTube, and three to five times a week for Facebook and Twitter. While expanding our social media activities, we have also expanded our monitoring of all our on-line media. This monitoring has revealed some surprising findings. For example, although we have a steadily growing list of followers (over 1,000 "likes" on Facebook and almost 2,500 "subscribers" YouTube), the use of social media has not significantly increased traffic to our main institutional web site. For the last three years, this site has maintained fairly consistent traffic at 1,000 to 2,000 visits/day. We do see a few extreme spikes in traffic, which can be up to an order of magnitude above normal, when a major web site links to one of our news releases. Since initiating our social networking sites, we have seen an increase in these types of spikes, but it is too early to establish cause and effect in this case. Another unexpected finding is that we are reaching very different

In this paper, authors suggest a model that reflects the role played by the Web site characteristics and the previous level of satisfaction as determinant factors of trust in the Web site. Also, authors consider the moderating effects of consumers' motives and inhibitors to purchase online. Results show that satisfaction with previous purchases, the Web site security and privacy policies, and service quality are the main determinants of trust. Also, the motives and inhibitors the individuals perceive when buying online determine the type of signals they consider to trust.

Rosenkrantz, Andrew B; Doshi, Ankur M

2016-01-01

To assess information regarding radiology practices on public transparency Web sites. Eight Web sites comparing radiology centers' price and quality were identified. Web site content was assessed. Six of eight Web sites reported examination prices. Other reported information included hours of operation (4/8), patient satisfaction (2/8), American College of Radiology (ACR) accreditation (3/8), on-site radiologists (2/8), as well as parking, accessibility, waiting area amenities, same/next-day reports, mammography follow-up rates, examination appropriateness, radiation dose, fellowship-trained radiologists, and advanced technologies (1/8 each). Transparency Web sites had a preponderance of price (and to a lesser extent service quality) information, risking fostering price-based competition at the expense of clinical quality.

Wang, Weiwen; Sun, Ran; Mulvehill, Alice M; Gilson, Courtney C; Huang, Linda L

2017-02-01

Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information. A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests. Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (p = .005) and confidence in finding reliable Internet-based health information (p = .058) increased. Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [J Nurs Educ. 2017;56(2):110-114.].

2015-04-27

Traditionally, postal surveys or face to face interviews are the main approaches for health researchers to obtain essential research data. However, with the prevalence of information technology and Internet, Web-based surveys are gaining popularity in health research. This study aims to report the process and outcomes of recruiting Chinese migrants through social network sites in Australia and to examine the sample characteristics of online recruitment by comparing the sample which was recruited by an online survey to a sample of Australian Chinese migrants collected by a postal survey. Descriptive analyses were performed to describe and compare the process and outcomes of online recruitment with postal survey questionnaires. Chi square tests and t tests were performed to assess the differences between the two samples for categorical and continuous variables respectively. In total, 473 Chinese migrants completed the online health survey from July to October 2013. Out of 426 participants recruited through the three Chinese social network sites in Australia, over 86.6% (369/426) were recruited within six weeks. Participants of the Web-based survey were younger, with a higher education level or had resided in Australia for less time compared to those recruited via a postal survey. However, there was no significant difference in gender, marital status, and professional occupation. The recruitment of Chinese migrants through social network sites in our online survey was feasible. Compared to a postal survey of Chinese migrants, the online survey attracted different group of Chinese migrants who may have diverse health needs and concerns. Our findings provided insightful information for researchers who are considering employing a Web-based approach to recruit migrants and ethnic minority participants.

The Atlas of Chinese World Wide Web Ecosystem Shaped by the Collective Attention Flows.

Lou, Xiaodan; Li, Yong; Gu, Weiwei; Zhang, Jiang

2016-01-01

The web can be regarded as an ecosystem of digital resources connected and shaped by collective successive behaviors of users. Knowing how people allocate limited attention on different resources is of great importance. To answer this, we embed the most popular Chinese web sites into a high dimensional Euclidean space based on the open flow network model of a large number of Chinese users' collective attention flows, which both considers the connection topology of hyperlinks between the sites and the collective behaviors of the users. With these tools, we rank the web sites and compare their centralities based on flow distances with other metrics. We also study the patterns of attention flow allocation, and find that a large number of web sites concentrate on the central area of the embedding space, and only a small fraction of web sites disperse in the periphery. The entire embedding space can be separated into 3 regions(core, interim, and periphery). The sites in the core (1%) occupy a majority of the attention flows (40%), and the sites (34%) in the interim attract 40%, whereas other sites (65%) only take 20% flows. What's more, we clustered the web sites into 4 groups according to their positions in the space, and found that similar web sites in contents and topics are grouped together. In short, by incorporating the open flow network model, we can clearly see how collective attention allocates and flows on different web sites, and how web sites connected each other.

Evaluation of E-Learning Web Sites Using Fuzzy Axiomatic Design Based Approach

Directory of Open Access Journals (Sweden)

2010-04-01

Full Text Available High quality web site has been generally recognized as a critical enabler to conduct online business. Numerous studies exist in the literature to measure the business performance in relation to web site quality. In this paper, an axiomatic design based approach for fuzzy group decision making is adopted to evaluate the quality of e-learning web sites. Another multi-criteria decision making technique, namely fuzzy TOPSIS, is applied in order to validate the outcome. The methodology proposed in this paper has the advantage of incorporating requirements and enabling reductions in the problem size, as compared to fuzzy TOPSIS. A case study focusing on Turkish e-learning websites is presented, and based on the empirical findings, managerial implications and recommendations for future research are offered.

Hand Society and Matching Program Web Sites Provide Poor Access to Information Regarding Hand Surgery Fellowship.

2016-08-01

The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

Web 2.0 is a term used to describe recent developments on the World Wide Web. The term is often used to describe the increased use of the web for user-generated content, collaboration, and social networking. However, Web 2.0 is a weakly defined concept, and it is unclear exactly what kind...... of technologies it covers. The objective of the paper is to develop a typology that can be used to categorize Web 2.0 technologies. Further, the paper will discuss which of these technologies are unique to Web 2.0. Often, Web 2.0 is described by way of different kinds of software; for instance, blogs, wikis......, podcasts, RSS, and social networking sites. The problem with this type of description is that it fails to distinguish between different types or categories of technologies. As an alternative, the typology developed in the paper distinguishes between technologies on basis of, how - and in which contexts...

In the era where Internet technology has grown rapidly, information is now at your fingertips. Web site is considered as an important medium and widely used whether for the purposes of promoting products and services or as an effective way to disseminate general information about the organization, companies or individuals. Nowadays, a general term such as Web 2.0 is almost out of date and is now entering the era of the Real World Web. For government agencies for instance, official web site is an important and effective tool for dissemination and communication of information to the public. In the view of Web master for a government agency, a number of issues and challenges may arise. They might face the same issues and challenges but they way to handle them are differ from one agency to another, depending on the culture, special rules and regulations applied and shared values among the staff. This paper will discuss these issues and challenges as well as applicable solutions based on our experiences. (author)

Web-based recruitment: effects of information, organizational brand, and attitudes toward a Web site on applicant attraction.

Science.gov (United States)

Allen, David G; Mahto, Raj V; Otondo, Robert F

2007-11-01

Recruitment theory and research show that objective characteristics, subjective considerations, and critical contact send signals to prospective applicants about the organization and available opportunities. In the generating applicants phase of recruitment, critical contact may consist largely of interactions with recruitment sources (e.g., newspaper ads, job fairs, organization Web sites); however, research has yet to fully address how all 3 types of signaling mechanisms influence early job pursuit decisions in the context of organizational recruitment Web sites. Results based on data from 814 student participants searching actual organization Web sites support and extend signaling and brand equity theories by showing that job information (directly) and organization information (indirectly) are related to intentions to pursue employment when a priori perceptions of image are controlled. A priori organization image is related to pursuit intentions when subsequent information search is controlled, but organization familiarity is not, and attitudes about a recruitment source also influence attraction and partially mediate the effects of organization information. Theoretical and practical implications for recruitment are discussed. (c) 2007 APA

Randomized 2-group trial with local tobacco control coalitions as the unit of randomization. Local communities (ie, counties) within the State of Colorado. Leaders and members in 34 local tobacco control coalitions funded by the state health department in Colorado. Two technical assistance Web sites: A Basic Web site with text-based information and a multimedia Enhanced Web site containing learning modules, resources, and communication features. Use of the Web sites in minutes, pages, and session and evaluations of coalition functioning on coalition development, conflict resolution, leadership satisfaction, decision-making satisfaction, shared mission, personal involvement, and organization involvement in survey of leaders and members. Coalitions that were defunded but had access to the multimedia Enhanced Web site during the Fully Funded period and after defunding continued to use it (treatment group × funding status × period, F(3,714) = 3.18, P = .0234). Coalitions with access to the Basic Web site had low Web site use throughout and use by defunded coalitions was nearly zero when funding ceased. Members in defunded Basic Web site coalitions reported that their coalitions functioned worse than defunded Enhanced Web site coalitions (coalition development: group × status, F(1,360) = 4.81, P = .029; conflict resolution: group × status, F(1,306) = 5.69, P = .018; leadership satisfaction: group × status, F(1,342) = 5.69, P = .023). The Enhanced Web site may have had a protective effect on defunded coalitions. Defunded coalitions may have increased their capacity by using the Enhanced Web site when fully funded or by continuing to use the available online resources after defunding

Framing medical tourism: an examination of appeal, risk, convalescence, accreditation, and interactivity in medical tourism web sites.

Mason, Alicia; Wright, Kevin B

2011-02-01

This exploratory study analyzed the content of medical tourism Web sites in an attempt to examine how they convey information about benefits and risks of medical procedures, how they frame credibility, and the degree to which these Web sites include interactive features for consumers. Drawing upon framing theory, the researchers content analyzed a sample of 66 medical tourism Web sites throughout the world. The results indicated that medical tourism Web sites largely promote the benefits of medical procedures while downplaying the risks, and relatively little information regarding the credibility of these services appears. In addition, the presentation of benefits/risks, credibility, and Web site interactivity were found to differ by region and type of facility. The authors discuss the implications of these findings concerning the framing of medical tourism Web site content, future directions for research, and limitations.

2010-01-01

3-D conformal radiotherapy is based on accurate target volumes delineation. Radio-anatomy knowledge's are useful but sometimes difficult to obtain. Moreover, the sources of recommendations for volume definition are disparate. We thus developed a free radio-anatomy web site dedicated to volumes delineation for radiation-oncologists (www.siriade.org). This web site is a search engine allowing to access to delineation characteristics of main tumours illustrated with clinical cases. It does not aim to provide guidelines. Its main purpose is to provide an iconographic training support with frequent up-datings. We present the features of this web site and one year connexion statistics. (authors)

Zlatić, V.; Božičević, M.; Štefančić, H.; Domazet, M.

2006-07-01

Wikipedia is a popular web-based encyclopedia edited freely and collaboratively by its users. In this paper we present an analysis of Wikipedias in several languages as complex networks. The hyperlinks pointing from one Wikipedia article to another are treated as directed links while the articles represent the nodes of the network. We show that many network characteristics are common to different language versions of Wikipedia, such as their degree distributions, growth, topology, reciprocity, clustering, assortativity, path lengths, and triad significance profiles. These regularities, found in the ensemble of Wikipedias in different languages and of different sizes, point to the existence of a unique growth process. We also compare Wikipedias to other previously studied networks.

The age and size of the CMS collaboration at the LHC means it now has many hundreds of inhomogeneous web sites and services and more than 100,000 documents. We describe a major initiative to create a single coherent CMS internal and public web site. This uses the Drupal web Content Management System (now supported by CERN/IT) on top of a standard LAMP stack (Linux, Apache, MySQL, and php/perl). The new navigation, content and search services are coherently integrated with numerous existing CERN services (CDS, EDMS, Indico, phonebook, Twiki) as well as many CMS internal Web services. We describe the information architecture; the system design, implementation and monitoring; the document and content database; security aspects; and our deployment strategy which ensured continual smooth operation of all systems at all times.

Montathar Faraon

2014-11-01

Full Text Available This study aimed to examine differences in influence between online news (e.g., New York Times and social networking sites (e.g., Facebook and Twitter on attitudes in political campaigns. In a web-based experiment, campaign, polls and election between two fictitious candidates were simulated. Participants’ explicit and implicit attitudes as well as voting behavior were assessed using self-report items and the Implicit Association Test (IAT. The results reveal that information emanating from online news had a significant influence on explicit and implicit attitudes while that of social networking sites did not. Overall, negative items had a stronger impact than positive ones, more so in online news compared to social networking sites. Negative information from either type of media was more likely to change participants’ explicit attitudes in a negative direction and as a consequence also change their vote. Practical implications of the findings and limitations of the study are discussed.

Diagnostic MDCT imaging requires a considerable number of images to be read. Moreover, the doctor who diagnoses a medical image is insufficient in Japan. Because of such a background, we have provided diagnostic assistance methods to medical screening specialists by developing a lung cancer screening algorithm that automatically detects suspected lung cancers in helical CT images, a coronary artery calcification screening algorithm that automatically detects suspected coronary artery calcification and a vertebra body analysis algorithm for quantitative evaluation of osteoporosis. We also have developed the teleradiology network system by using web medical image conference system. In the teleradiology network system, the security of information network is very important subjects. Our teleradiology network system can perform Web medical image conference in the medical institutions of a remote place using the web medical image conference system. We completed the basic proof experiment of the web medical image conference system with information security solution. We can share the screen of web medical image conference system from two or more web conference terminals at the same time. An opinion can be exchanged mutually by using a camera and a microphone that are connected with the workstation that builds in some diagnostic assistance methods. Biometric face authentication used on site of teleradiology makes "Encryption of file" and "Success in login" effective. Our Privacy and information security technology of information security solution ensures compliance with Japanese regulations. As a result, patients' private information is protected. Based on these diagnostic assistance methods, we have developed a new computer-aided workstation and a new teleradiology network that can display suspected lesions three-dimensionally in a short time. The results of this study indicate that our radiological information system without film by using computer-aided diagnosis

2014-11-01

Full Text Available Online social networks have become a seamless and critical online communication platform for personal interactions. They are a powerful tool that businesses are using to expand among domestic markets. The increase in participation in online social networking can and has caused damage to individuals and organizations, and the issuance of trust has become a concern on the social web. The factors determining the reputation of persons (customers in the real world may relate to the factors of reputation on the social web, though relative to how trust is established in the physical world, establishing trust on the social web can be fairly difficult. Determining how to trust another individual’s online social profile becomes critical in initiating any interaction on the social web. Rather than focusing on content on the social network page, this research proposes and examines the application of user reputations to determine whether the trust should be issued on the social web. A top-level framework to establish trust in an identity on the Social Network Sites (SNS as a function of the users’ associations, usage patterns and reputation on the social web is presented.

2004-01-01

The Korea Atomic Energy Research Institute (KAERI) is actively participating in the Asian Network for Education in Nuclear Technology (ANENT), which is an IAEA activity to promote nuclear knowledge management. This has led KAERI to conduct a web-based networking for nuclear education and training in Asia. The networking encompasses the establishment of a relevant website and a system for a sustainable operation of the website. The established ANENT website features function as a database providing collected information, a link facilitating a systematic worldwide access to relevant websites, and an activity implementation for supporting the individual tasks of ANENT. The required information is being collected and loaded onto the database, and the website will be improved step by step. Consequently, networking is expected to play an important role, through cooperating with other networks, and thus contributing to a future global network for a sustainable development of nuclear technology.

Badarudeen, Sameer; Unes Kunju, Shebna

2008-01-01

One of the goals of the American Academy of Orthopaedic Surgeons (AAOS) is to disseminate patient education materials that suit the readability skills of the patient population. According to standard guidelines from healthcare organizations, the readability of patient education materials should be no higher than the sixth-grade level. We hypothesized the readability level of patient education materials available on the AAOS Web site would be higher than the recommended grade level, regardless when the material was available online. Readability scores of all articles from the AAOS Internet-based patient information Web site, “Your Orthopaedic Connection,” were determined using the Flesch-Kincaid grade formula. The mean Flesch-Kincaid grade level of the 426 unique articles was 10.43. Only 10 (2%) of the articles had the recommended readability level of sixth grade or lower. The readability of the articles did not change with time. Our findings suggest the majority of the patient education materials available on the AAOS Web site had readability scores that may be too difficult for comprehension by a substantial portion of the patient population.

In their own words: why teenagers don't use social networking sites.

Science.gov (United States)

Baker, Rosland K; White, Katherine M

2011-06-01

We explored common reasons for non-use of the rapidly growing popularity of social networking sites among a sample of Australian adolescents (N = 69). Transcripts were coded by grouping responses along similar themes for non-use that had been commonly stated by participants. The primary reasons offered by adolescents were: lack of motivation, poor use of time, preference for other forms of communication, preference for engaging in other activities, cybersafety concerns, and a dislike of self-presentation online. The identification of these themes allows for a greater understanding of teenagers' decisions not to engage in the popular medium of communication and points to possible strategies that could be utilised by Web site developers in efforts to appeal to a wider teenage audience.

Dynamics of a macroscopic model characterizing mutualism of search engines and web sites

Science.gov (United States)

Wang, Yuanshi; Wu, Hong

2006-05-01

We present a model to describe the mutualism relationship between search engines and web sites. In the model, search engines and web sites benefit from each other while the search engines are derived products of the web sites and cannot survive independently. Our goal is to show strategies for the search engines to survive in the internet market. From mathematical analysis of the model, we show that mutualism does not always result in survival. We show various conditions under which the search engines would tend to extinction, persist or grow explosively. Then by the conditions, we deduce a series of strategies for the search engines to survive in the internet market. We present conditions under which the initial number of consumers of the search engines has little contribution to their persistence, which is in agreement with the results in previous works. Furthermore, we show novel conditions under which the initial value plays an important role in the persistence of the search engines and deduce new strategies. We also give suggestions for the web sites to cooperate with the search engines in order to form a win-win situation.

Gesler, Wilbert M; Arcury, Thomas A; Skelly, Anne H; Nash, Sally; Soward, April; Dougherty, Molly

2006-12-01

This paper reports on the methods used and results of a study that identified specific places within a community that have the potential to be sites for a diabetes prevention program. These sites, termed diabetes knowledge network nodes (DKNNs), are based on the concept of socio-spatial knowledge networks (SSKNs), the web of social relationships within which people obtain knowledge about type 2 diabetes. The target population for the study was working poor African Americans, Latinos, and European Americans of both sexes in a small rural southern town who had not been diagnosed with diabetes. Information was collected from a sample of 121 respondents on the places they visited in carrying out their daily activities. Data on number of visits to specific sites, degree of familiarity with these sites, and ratings of sites as places to receive diabetes information were used to develop three categories of DKNNs for six subgroups based on ethnicity and sex. Primary potential sites of importance to one or more subgroups included churches, grocery stores, drugstores, the local library, a beauty salon, laundromats, a community service agency, and a branch of the County Health Department. Secondary potential sites included gas stations, restaurants, banks, and post offices. Latent potential sites included three medical facilities. Most of the DKNNs were located either in the downtown area or in one of two shopping areas along the most used highway that passed through the town. The procedures used in this study can be generalized to other communities and prevention programs for other chronic diseases.

Full Text Available In order to serve the Islamic researchers, providing a web site is inevitable for Islamic Universities which are in transition from the real to the virtual world and. Today, almost all the major universities in Islamic community have websites. But, in the realization of their mission, it is not clear to what extant these universities were successful in terms of information dissemination. The aim of this paper was to determine the core web sites and evaluate the effectiveness, ranking and collaboration rate among these websites. The formulas of core website determination, co-links and in-links analysis and revised web impact factor were used beside cluster and multidimensional analysis methods in this study. Results showed that "King Saud University" website in Saudi Arabia had the highest visibility and the most authoritative website among all university websites. Also, co-link analysis showed that major Islamic university websites had collaboration in 12 clusters based on clustering analysis and in 11 clusters based on multidimensional analysis, where two of them (Iran and Turkey were national clusters in cluster analysis method. Results analysis indicated that web designers in these universities must identify how to attract links and web traffic in order to promote the quality and content of websites. However, the ultimate success of a website was dependent upon factors such as quality, size, language, and the approximate age of a website which was not limited to one or two factors.

Expert knowledge in palliative care on the World Wide Web: palliativedrugs.org.

Science.gov (United States)

Gavrin, Jonathan

2009-01-01

In my last Internet-related article, I speculated that social networking would be the coming wave in the effort to share knowledge among experts in various disciplines. At the time I did not know that a palliative care site on the World Wide Web (WWW), palliativedrugs.com, already provided the infrastructure for sharing expert knowledge in the field. The Web site is an excellent traditional formulary but it is primarily devoted to "unlicensed" ("off-label") use of medications in palliative care, something we in the specialty often do with little to support our interventions except shared knowledge and experience. There is nothing fancy about this Web site. In a good way, its format is a throwback to Web sites of the 1990s. In only the loosest sense can one describe it as "multimedia." Yet, it provides the perfect forum for expert knowledge and is a "must see" resource. Its existing content is voluminous and reliable, filtered and reviewed by renowned clinicians and educators in the field. Although its origin and structure were not specifically designed for social or professional networking, the Web site's format makes it a natural way for practitioners around the world to contribute to an ever-growing body of expertise in palliative care.

Network topology: patterns and mechanisms in plant-herbivore and host-parasitoid food webs.

Science.gov (United States)

Cagnolo, Luciano; Salvo, Adriana; Valladares, Graciela

2011-03-01

1. Biological communities are organized in complex interaction networks such as food webs, which topology appears to be non-random. Gradients, compartments, nested subsets and even combinations of these structures have been shown in bipartite networks. However, in most studies only one pattern is tested against randomness and mechanistic hypotheses are generally lacking. 2. Here we examined the topology of regional, coexisting plant-herbivore and host-parasitoid food webs to discriminate between the mentioned network patterns. We also evaluated the role of species body size, local abundance, regional frequency and phylogeny as determinants of network topology. 3. We found both food webs to be compartmented, with interaction range boundaries imposed by host phylogeny. Species degree within compartments was mostly related to their regional frequency and local abundance. Only one compartment showed an internal nested structure in the distribution of interactions between species, but species position within this compartment was unrelated to species size or abundance. 4. These results suggest that compartmentalization may be more common than previously considered, and that network structure is a result of multiple, hierarchical, non-exclusive processes. © 2010 The Authors.

The studies of biological, disease, and pharmacological networks are facilitated by the systems-level investigations using computational tools. In particular, the network descriptors developed in other disciplines have found increasing applications in the study of the protein, gene regulatory, metabolic, disease, and drug-targeted networks. Facilities are provided by the public web servers for computing network descriptors, but many descriptors are not covered, including those used or useful for biological studies. We upgraded the PROFEAT web server http://bidd2.nus.edu.sg/cgi-bin/profeat2016/main.cgi for computing up to 329 network descriptors and protein-protein interaction descriptors. PROFEAT network descriptors comprehensively describe the topological and connectivity characteristics of unweighted (uniform binding constants and molecular levels), edge-weighted (varying binding constants), node-weighted (varying molecular levels), edge-node-weighted (varying binding constants and molecular levels), and directed (oriented processes) networks. The usefulness of the network descriptors is illustrated by the literature-reported studies of the biological networks derived from the genome, interactome, transcriptome, metabolome, and diseasome profiles.

Transition Region Explorer (TREx) is a ground-based sensor web of optical and radio instruments that is presently being deployed across central Canada. The project consists of an array of co-located blue-line, full-colour, and near-infrared all-sky imagers, imaging riometers, proton aurora spectrographs, and GNSS systems. A key goal of the TREx project is to create the world's first (artificial) intelligent sensor web for remote sensing space weather. The sensor web will autonomously control and coordinate instrument operations in real-time. To accomplish this, we will use real-time in-line analytics of TREx and other data to dynamically switch between operational modes. An operating mode could be, for example, to have a blue-line imager gather data at a one or two orders of magnitude higher cadence than it operates for its `baseline' mode. The software decision to increase the imaging cadence would be in response to an anticipated increase in auroral activity or other programmatic requirements. Our first test for TREx's sensor web technologies is to develop the capacity to autonomously alter the TREx operating mode prior to a substorm expansion phase onset. In this paper, we present our neural network analysis of historical optical and riometer data and our ability to predict an optical onset. We explore the preliminary insights into using a neural network to pick out trends and features which it deems are similar among substorms.

2003-01-01

The purpose of this study was to determine the current level of knowledge and awareness of hunger-related issues among a convenience sample of Delawareans. We also assessed whether raising knowledge and awareness of the hunger problem through the FBD's newly designed web site would encourage participation in antihunger activities. Via e-mail, 1,719 individuals were invited to participate in a three-phase, online survey, and 392 agreed. Phase-I questions were answered prior to viewing the web site, phase II (n=217) immediately afterward, and phase III (n=61) six weeks later. Responses indicated a high level of awareness about general hunger issues but specific knowledge proved to be at a lower level. No statistically significant differences were noted when data were collapsed across gender, age, educational level, or work setting. In a six-week post-survey, 41% of subjects were motivated by the web site to engage in an antihunger activity; 34% had told others about the web site and indicated it may be a useful tool in antihunger outreach efforts for the FBD.

Genomics provided us with an unprecedented quantity of data on the genes that are activated or repressed in a wide range of phenotypes. We have increasingly come to recognize that defining the networks and pathways underlying these phenotypes requires both the integration of multiple data types and the development of advanced computational methods to infer relationships between the genes and to estimate the predictive power of the networks through which they interact. To address these issues we have developed Predictive Networks (PN), a flexible, open-source, web-based application and data services framework that enables the integration, navigation, visualization and analysis of gene interaction networks. The primary goal of PN is to allow biomedical researchers to evaluate experimentally derived gene lists in the context of large-scale gene interaction networks. The PN analytical pipeline involves two key steps. The first is the collection of a comprehensive set of known gene interactions derived from a variety of publicly available sources. The second is to use these 'known' interactions together with gene expression data to infer robust gene networks. The PN web application is accessible from http://predictivenetworks.org. The PN code base is freely available at https://sourceforge.net/projects/predictivenets/.

Cooperation and contagion in web-based, networked public goods experiments.

Directory of Open Access Journals (Sweden)

Siddharth Suri

Full Text Available A longstanding idea in the literature on human cooperation is that cooperation should be reinforced when conditional cooperators are more likely to interact. In the context of social networks, this idea implies that cooperation should fare better in highly clustered networks such as cliques than in networks with low clustering such as random networks. To test this hypothesis, we conducted a series of web-based experiments, in which 24 individuals played a local public goods game arranged on one of five network topologies that varied between disconnected cliques and a random regular graph. In contrast with previous theoretical work, we found that network topology had no significant effect on average contributions. This result implies either that individuals are not conditional cooperators, or else that cooperation does not benefit from positive reinforcement between connected neighbors. We then tested both of these possibilities in two subsequent series of experiments in which artificial seed players were introduced, making either full or zero contributions. First, we found that although players did generally behave like conditional cooperators, they were as likely to decrease their contributions in response to low contributing neighbors as they were to increase their contributions in response to high contributing neighbors. Second, we found that positive effects of cooperation were contagious only to direct neighbors in the network. In total we report on 113 human subjects experiments, highlighting the speed, flexibility, and cost-effectiveness of web-based experiments over those conducted in physical labs.

Intoxigenic digital spaces? Youth, social networking sites and alcohol marketing.

Science.gov (United States)

Griffiths, Richard; Casswell, Sally

2010-09-01

To examine how young people in New Zealand engage with alcohol and reproduce alcohol marketing messages and alcohol-related branding in 'Bebo', a popular social networking site (SNS) on the Internet. Data are drawn from information posted on approximately 150 Bebo Web pages and analysed by way of textual analysis and cyberspace ethnography. Social networking sites, such as Bebo, provide young people with a digital space in which to share a range of alcohol marketing messages via peer-to-peer transmission. Bebo also enables youth to communicate to one another how they consume alcohol and their views of alcohol marketing messages. The information being shared by young people who use Bebo is openly provided in the form of personal information, forum comments, digital photographs and answering quizzes about their engagement with alcohol. Through this sharing of information in the digital Internet environment, young people are creating 'intoxigenic social identities' as well as 'intoxigenic digital spaces' that further contribute towards the normalisation of youth consumption of alcohol. A better understanding of how youth are using the Internet to share their experiences with alcohol and engagement with alcohol-related messages is crucial to public health research as alcohol marketing practices rapidly evolve.

Friedman, Daniela B; Koskan, Alexis; Rose, India D

2011-03-01

Little is known about prostate cancer (PrCA) screening information on participatory, interactive, and consumer-generated websites collectively referred to as Web 2.0. A content analysis was conducted of PrCA resources on four highly trafficked Web 2.0 social bookmarking sites. A total of 127 webpages were analyzed. Most content was from news websites (48.9%) and blogs (37.8%). PrCA screening was mentioned on 95.3% of pages; only 30.7% discussed the prostate-specific antigen test. Less than half (43.8%) mentioned current screening guidelines. PrCA content is inconsistent on Web 2.0 sites. Future research should assess the readability and usability of Web 2.0 cancer resources.

Plankton food-web functioning in anthropogenically impacted coastal waters (SW Mediterranean Sea): An ecological network analysis

The study is the first attempt to (i) model spring food webs in three SW Mediterranean ecosystems which are under different anthropogenic pressures and (ii) to project the consequence of this stress on their function. Linear inverse models were built using the Monte Carlo method coupled with Markov Chains to characterize the food-web status of the Lagoon, the Channel (inshore waters under high eutrophication and chemical contamination) and the Bay of Bizerte (offshore waters under less anthropogenic pressure). Ecological network analysis was used for the description of structural and functional properties of each food web and for inter-ecosystem comparisons. Our results showed that more carbon was produced by phytoplankton in the inshore waters (966-1234 mg C m-2 d-1) compared to the Bay (727 mg C m-2 d-1). The total ecosystem carbon inputs into the three food webs was supported by high primary production, which was mainly due to >10 μm algae. However, the three carbon pathways were characterized by low detritivory and a high herbivory which was mainly assigned to protozooplankton. This latter was efficient in channelling biogenic carbon. In the Lagoon and the Channel, foods webs acted almost as a multivorous structure with a tendency towards herbivorous one, whereas in the Bay the herbivorous pathway was more dominant. Ecological indices revealed that the Lagoon and the Channel food webs/systems had high total system throughput and thus were more active than the Bay. The Bay food web, which had a high relative ascendency value, was more organized and specialized. This inter-ecosystem difference could be due to the varying levels of anthropogenic impact among sites. Indeed, the low value of Finn's cycling index indicated that the three systems are disturbed, but the Lagoon and the Channel, with low average path lengths, appeared to be more stressed, as both sites have undergone higher chemical pollution and nutrient loading. This study shows that ecosystem models

The catalytic site identification web server provides the innovative capability to find structural matches to a user-specified catalytic site among all Protein Data Bank proteins rapidly (in less than a minute). The server also can examine a user-specified protein structure or model to identify structural matches to a library of catalytic sites. Finally, the server provides a database of pre-calculated matches between all Protein Data Bank proteins and the library of catalytic sites. The database has been used to derive a set of hypothesized novel enzymatic function annotations. In all cases, matches and putative binding sites (protein structure and surfaces) can be visualized interactively online. The website can be accessed at http://catsid.llnl.gov. PMID:23680785

A web server for analysis, comparison and prediction of protein ligand binding sites.

Singh, Harinder; Srivastava, Hemant Kumar; Raghava, Gajendra P S

2016-03-25

One of the major challenges in the field of system biology is to understand the interaction between a wide range of proteins and ligands. In the past, methods have been developed for predicting binding sites in a protein for a limited number of ligands. In order to address this problem, we developed a web server named 'LPIcom' to facilitate users in understanding protein-ligand interaction. Analysis, comparison and prediction modules are available in the "LPIcom' server to predict protein-ligand interacting residues for 824 ligands. Each ligand must have at least 30 protein binding sites in PDB. Analysis module of the server can identify residues preferred in interaction and binding motif for a given ligand; for example residues glycine, lysine and arginine are preferred in ATP binding sites. Comparison module of the server allows comparing protein-binding sites of multiple ligands to understand the similarity between ligands based on their binding site. This module indicates that ATP, ADP and GTP ligands are in the same cluster and thus their binding sites or interacting residues exhibit a high level of similarity. Propensity-based prediction module has been developed for predicting ligand-interacting residues in a protein for more than 800 ligands. In addition, a number of web-based tools have been integrated to facilitate users in creating web logo and two-sample between ligand interacting and non-interacting residues. In summary, this manuscript presents a web-server for analysis of ligand interacting residue. This server is available for public use from URL http://crdd.osdd.net/raghava/lpicom .

Network and User-Perceived Performance of Web Page Retrievals

Kruse, Hans; Allman, Mark; Mallasch, Paul

1998-01-01

The development of the HTTP protocol has been driven by the need to improve the network performance of the protocol by allowing the efficient retrieval of multiple parts of a web page without the need for multiple simultaneous TCP connections between a client and a server. We suggest that the retrieval of multiple page elements sequentially over a single TCP connection may result in a degradation of the perceived performance experienced by the user. We attempt to quantify this perceived degradation through the use of a model which combines a web retrieval simulation and an analytical model of TCP operation. Starting with the current HTTP/l.1 specification, we first suggest a client@side heuristic to improve the perceived transfer performance. We show that the perceived speed of the page retrieval can be increased without sacrificing data transfer efficiency. We then propose a new client/server extension to the HTTP/l.1 protocol to allow for the interleaving of page element retrievals. We finally address the issue of the display of advertisements on web pages, and in particular suggest a number of mechanisms which can make efficient use of IP multicast to send advertisements to a number of clients within the same network.

Digital imaging and communications in medicine (DICOM) 3.0 standard provides the baseline for the picture archiving and communication systems (PACS). The development of Internet and various communication media initiated demand for non-DICOM access to PACS systems. Ever-increasing utilization of the web browsers, laptops and handheld devices, as opposed to desktop applications and static organizational computers, lead to development of different web technologies. The DICOM standard officials accepted those subsequently as tools of alternative access. This paper provides an overview of the current state of development of the web access technology to the DICOM repositories. It presents a different approach of using HTML5 features of the web browsers through the JavaScript language and the WebSocket protocol by enabling real-time communication with DICOM repositories. JavaScript DICOM network library, DICOM to WebSocket proxy and a proof-of-concept web application that qualifies as a DICOM 3.0 device were developed.

This summer I assisted the RPT Program Office in developing a design plan to update their existing website to current NASA web standards. The finished website is intended for the general public, specifically potential customers interested in learning about NASA's chemical rocket test facility capabilities and test assignment process. The goal of the website is to give the public insight about the purpose and function of the RPT Program. Working on this project gave me the opportunity to learn skills necessary for effective project management. The RPT Program Office manages numerous facilities so they are required to travel often to other sites for meetings throughout the year. Maneuvering around the travel schedule of the office and the workload priority of the IT Department proved to be quite the challenge. I overcame the travel schedule of the office by frequently communicating and checking in with my mentor via email and telephone.

Nine Maori web sites were searched using a list of 44 key concepts in Maori culture. We registered how many pages within a particular web site contain each of the key concepts. These numbers were set up in a data matrix for further statistical analysis. The Multidimensional Scaling method was used to construct a spatial representation of Maori web sites in the space generated by the key concepts in Maori culture. Using the correlation coefficients between derived dimensions and the key concepts we interpreted three dimensions as General Cultural, Intra-tribe Dynamics and Educational. The position of each Maori web site in this space has been located and described.

The web-based networked virtual instrument (NVI) system is designed by using the object oriented methodology (OOM). The architecture of the NVI system consists of two major parts: client-web server interaction and instrument server-virtual instrument (VI) communication. The web server communicates with the instrument server and the clients connected to it over the Internet, and it handles identifying the user's name, managing the connection between the user and the instrument server, adding, removing and configuring VI's information. The instrument server handles setting the parameters of VI, confirming the condition of VI and saving the VI's condition information into the database. The NVI system is required to be a general-purpose measurement system that is easy to maintain, adapt and extend. Virtual instruments are connected to the instrument server and clients can remotely configure and operate these virtual instruments. An application of The NVI system is given in the end of the paper

Full Text Available Corporate Web sites have become very popular media of information over the past decade. The Investor Relations Society published best practice Web site guidelines in December 2006 to guide companies seeking to improve the quality of their on-line communication with investors via their corporate Web sites. Guidelines were given for presentation (the way in which information is communicated and content (the information that is communicated. This study focused only on content. A 20-point checklist was developed from the prescribed best practice. The checklist focused on the six categories of best practice that entail company information, annual reports of the current year and archive, relevant news, shareholder information, bondholder information, corporate governance and corporate responsibility. Seventy-eight companies in Africa (40 from South Africa and 38 from the 'rest of Africa', that is Egypt, Kenya, Morocco, Nigeria and Tunisia were evaluated against this checklist. Companies from the 'rest of Africa' rated lower than South African companies in all categories on the checklist. Although South African companies received ratings above 90% for all categories, besides bondholder information, many of these companies do not supply shareholder, corporate governance and corporate responsibility information via dedicated sections on their corporate Web sites. The results for companies from the 'rest of Africa' were disappointing, especially with regard to communication of annual reports, shareholder information, bondholder information and corporate responsibility. Although possible reasons for these disappointing results are discussed in this study, further research should be conducted to determine the reason(s why important elements of information are not communicated via corporate Web sites.

Now day’s web applications are very high in the rate of usage due to their user friendly environment and getting any information via internet but these web applications are affected by lot of threats. CSRF attack is one of the serious threats to web applications which is based on the vulnerabilities present in the normal web request and response of HTTP protocol. It is hard to detect but hence still it is present in most of the existing web applications. In CSRF attack, without user knowledge the unwanted actions on a reliable websites are forced to happen. So it is placed in OWASP’s top 10 Web Application attacks list. My proposed work is to do a real time scan of CSRF vulnerability attack in given URL of the web applications as well as local host address for any organization using python language. Client side detection of CSRF is depended on Form count which is presented in that given web site.

Mimoza: web-based semantic zooming and navigation in metabolic networks.

Zhukova, Anna; Sherman, David J

2015-02-26

The complexity of genome-scale metabolic models makes them quite difficult for human users to read, since they contain thousands of reactions that must be included for accurate computer simulation. Interestingly, hidden similarities between groups of reactions can be discovered, and generalized to reveal higher-level patterns. The web-based navigation system Mimoza allows a human expert to explore metabolic network models in a semantically zoomable manner: The most general view represents the compartments of the model; the next view shows the generalized versions of reactions and metabolites in each compartment; and the most detailed view represents the initial network with the generalization-based layout (where similar metabolites and reactions are placed next to each other). It allows a human expert to grasp the general structure of the network and analyze it in a top-down manner Mimoza can be installed standalone, or used on-line at http://mimoza.bordeaux.inria.fr/ , or installed in a Galaxy server for use in workflows. Mimoza views can be embedded in web pages, or downloaded as COMBINE archives.

Sigi Goode

2002-11-01

Full Text Available There is little published research on the role of consultants in technology adoption. Given the increasing popularity of the World Wide Web in commercial environments and the number of consultants now offering web development services, some analysis into the effects of their engagement would be of benefit. In an extension of an ongoing study, an existing sample of 113 World Wide Web adopters was used to examine the nature of World Wide Web site use with respect to consultant and Internet Service Provider (ISP engagement. Analysis was also conducted into the use of consultants and ISPs as developers and maintainers of these sites. This preliminary research finds a number of interesting outcomes. No significant relationship is found between consultant or ISP engagement and World Wide Web site use, regardless of whether the consultant was engaged as site developer or site maintainer. The study raises a number of additional findings that are of interest but are not directly related to this study. These findings merit further research.

Transgenic crops among the most controversial "science and society" issues of recent years. Because of the complex techniques involved in creating these crops and the polarized debate over their risks and beliefs, a critical need has arisen for accessible and balanced information on this technology. World Wide Web sites offer several advantages for disseminating information on a fast-changing technical topic, including their global accessibility; and their ability to update information frequently, incorporate multimedia formats, and link to networks of other sites. An alliance between two complementary web sites at Colorado State University and the University of Nebraska-Lincoln takes advantage of the web environment to help fill the need for public information on crop genetic engineering. This article describes the objectives and features of each site. Viewership data and other feedback have shown these web sites to be effective means of reaching public audiences on a complex scientific topic.

2005-01-01

In siting a repository for high level radioactive wastes (HLW), it is essential for consensus building intelligibly and visually present why and how the area is selected as a suitable site. However 'information asymmetry' exists especially between society and an implementation body because various types of investigation, analysis and assessment are implemented in site characterization on the basis of a wide variety of advanced science and technology. Communication between experts (e.g. surveyors and modelers) is also important for efficient and reliable site investigation/ characterization. The Web-based Site Investigation Flow Diagram (SIFD) has been developed as a tool for information sharing among stake holders and society-jointed decision making. To test applicability of the SIFD, virtual site characterization ('dry run') is performed using the existing site investigation data. It is concluded that the web-based SIFD enhance traceability and transparency of the site investigation/ characterization, and therefore it would be a powerful communication tool among experts for efficient and reliable site investigation/characterization and among stake holders for consensus building

DECENTRALIZED SOCIAL NETWORK SERVICE USING THE WEB HOSTING SERVER FOR PRIVACY PRESERVATION

Directory of Open Access Journals (Sweden)

Yoonho Nam

2013-10-01

Full Text Available In recent years, the number of subscribers of the social network services such as Facebook and Twitter has increased rapidly. In accordance with the increasing popularity of social network services, concerns about user privacy are also growing. Existing social network services have a centralized structure that a service provider collects all the user’s profile and logs until the end of the connection. The information collected typically useful for commercial purposes, but may lead to a serious user privacy violation. The user’s profile can be compromised for malicious purposes, and even may be a tool of surveillance extremely. In this paper, we remove a centralized structure to prevent the service provider from collecting all users’ information indiscriminately, and present a decentralized structure using the web hosting server. The service provider provides only the service applications to web hosting companies, and the user should select a web hosting company that he trusts. Thus, the user’s information is distributed, and the user’s privacy is guaranteed from the service provider.

The DIMA web resource--exploring the protein domain network.

Science.gov (United States)

Pagel, Philipp; Oesterheld, Matthias; Stümpflen, Volker; Frishman, Dmitrij

2006-04-15

Conserved domains represent essential building blocks of most known proteins. Owing to their role as modular components carrying out specific functions they form a network based both on functional relations and direct physical interactions. We have previously shown that domain interaction networks provide substantially novel information with respect to networks built on full-length protein chains. In this work we present a comprehensive web resource for exploring the Domain Interaction MAp (DIMA), interactively. The tool aims at integration of multiple data sources and prediction techniques, two of which have been implemented so far: domain phylogenetic profiling and experimentally demonstrated domain contacts from known three-dimensional structures. A powerful yet simple user interface enables the user to compute, visualize, navigate and download domain networks based on specific search criteria. http://mips.gsf.de/genre/proj/dima

QuIN: A Web Server for Querying and Visualizing Chromatin Interaction Networks.

Asa Thibodeau

2016-06-01

Full Text Available Recent studies of the human genome have indicated that regulatory elements (e.g. promoters and enhancers at distal genomic locations can interact with each other via chromatin folding and affect gene expression levels. Genomic technologies for mapping interactions between DNA regions, e.g., ChIA-PET and HiC, can generate genome-wide maps of interactions between regulatory elements. These interaction datasets are important resources to infer distal gene targets of non-coding regulatory elements and to facilitate prioritization of critical loci for important cellular functions. With the increasing diversity and complexity of genomic information and public ontologies, making sense of these datasets demands integrative and easy-to-use software tools. Moreover, network representation of chromatin interaction maps enables effective data visualization, integration, and mining. Currently, there is no software that can take full advantage of network theory approaches for the analysis of chromatin interaction datasets. To fill this gap, we developed a web-based application, QuIN, which enables: 1 building and visualizing chromatin interaction networks, 2 annotating networks with user-provided private and publicly available functional genomics and interaction datasets, 3 querying network components based on gene name or chromosome location, and 4 utilizing network based measures to identify and prioritize critical regulatory targets and their direct and indirect interactions.QuIN's web server is available at http://quin.jax.org QuIN is developed in Java and JavaScript, utilizing an Apache Tomcat web server and MySQL database and the source code is available under the GPLV3 license available on GitHub: https://github.com/UcarLab/QuIN/.

Application of neural networks to waste site screening

International Nuclear Information System (INIS)

Dabiri, A.E.; Garrett, M.; Kraft, T.; Hilton, J.; VanHammersveld, M.

1993-02-01

Waste site screening requires knowledge of the actual concentrations of hazardous materials and rates of flow around and below the site with time. The present approach consists primarily of drilling boreholes near contaminated sites and chemically analyzing the extracted physical samples and processing the data. This is expensive and time consuming. The feasibility of using neural network techniques to reduce the cost of waste site screening was investigated. Two neural network techniques, gradient descent back propagation and fully recurrent back propagation were utilized. The networks were trained with data received from Westinghouse Hanford Corporation. The results indicate that the network trained with the fully recurrent technique shows satisfactory generalization capability. The predicted results are close to the results obtained from a mathematical flow prediction model. It is possible to develop a new tool to predict the waste plume, thus substantially reducing the number of the bore sites and samplings. There are a variety of applications for this technique in environmental site screening and remediation. One of the obvious applications would be for optimum well siting. A neural network trained from the existing sampling data could be utilized to decide where would be the best position for the next bore site. Other applications are discussed in the report

The use of social media by dermatology journals and professional and patient-centered dermatology organizations remains largely unknown and, to our knowledge, has yet to be fully evaluated. To evaluate and quantify the extent of involvement of dermatology journals, professional dermatology organizations, and dermatology-related patient advocate groups on social networking sites. We obtained an archived list of 102 current dermatology journals from SCImago on the World Wide Web and used the list to investigate Facebook, Twitter, and individual journal websites for the presence of social media accounts. We identified professional and patient-centered dermatology organization activity on social networks through queries of predetermined search terms on Google, Facebook, Twitter, and LinkedIn. The activity of each entity was documented by recording the following metrics of popularity: the numbers of Facebook "likes," Twitter "followers," and LinkedIn "members." The numbers of Facebook likes, Twitter followers, and LinkedIn members corresponding to each dermatology journal and each professional and patient-related dermatology organization. On July 17, 2012, of the 102 dermatology journals ranked by SCImago, 12.7% were present on Facebook and 13.7% on Twitter. We identified popular dermatology journals based on Facebook likes and Twitter followers, led by the Journal of the American Academy of Dermatology and Dermatology Times, respectively. Popular professional dermatology organizations included dermRounds Dermatology Network (11 251 likes on Facebook and 2900 followers on Twitter). The most popular dermatology patient-centered organizations were the Skin Cancer Foundation (20 119 likes on Facebook), DermaTalk (21 542 followers on Twitter), and the National Psoriasis Foundation (200 members on LinkedIn). Patient-centered and professional dermatology organizations use social networking sites; however, academic journals tend to lag behind significantly. Although some

The HIV Vaccine Trials Network (HVTN) is a global network of 28 clinical trial sites dedicated to identifying an effective HIV vaccine. Cryopreservation of high-quality peripheral blood mononuclear cells (PBMC) is critical for the assessment of vaccine-induced cellular immune functions. The HVTN PBMC Quality Management Program is designed to ensure that viable PBMC are processed, stored and shipped for clinical trial assays from all HVTN clinical trial sites. The program has evolved by developing and incorporating best practices for laboratory and specimen quality and implementing automated, web-based tools. These tools allow the site-affiliated processing laboratories and the central Laboratory Operations Unit to rapidly collect, analyze and report PBMC quality data. The HVTN PBMC Quality Management Program includes five key components: 1) Laboratory Assessment, 2) PBMC Training and Certification, 3) Internal Quality Control, 4) External Quality Control (EQC), and 5) Assay Specimen Quality Control. Fresh PBMC processing data is uploaded from each clinical site processing laboratory to a central HVTN Statistical and Data Management Center database for access and analysis on a web portal. Samples are thawed at a central laboratory for assay or specimen quality control and sample quality data is uploaded directly to the database by the central laboratory. Four year cumulative data covering 23,477 blood draws reveals an average fresh PBMC yield of 1.45×10(6)±0.48 cells per milliliter of useable whole blood. 95% of samples were within the acceptable range for fresh cell yield of 0.8-3.2×10(6) cells/ml of usable blood. Prior to full implementation of the HVTN PBMC Quality Management Program, the 2007 EQC evaluations from 10 international sites showed a mean day 2 thawed viability of 83.1% and a recovery of 67.5%. Since then, four year cumulative data covering 3338 specimens used in immunologic assays shows that 99.88% had acceptable viabilities (>66%) for use in

How Less Alienation Creates More Exploitation? Audience Labour on Social Network Sites.

Directory of Open Access Journals (Sweden)

Eran Fisher

2012-05-01

Full Text Available Abstract: The notion of audience labour has been an important contribution to Marxist political economy of the media. It revised the traditional political economy analysis, which focused on media ownership, by suggesting that media was also a site of production, constituting particular relations of production. Such analysis highlighted the active role of audience in the creation of media value as both commodities and workers, thus pointing to audience exploitation. Recently, in light of paradigmatic transformations in the media environment – particularly the emergence of Web 2.0 and social network sites – there has been a renewed interest in such analysis, and a reexamination of audience exploitation. Focusing on Facebook as a case-study, this article examines audience labour on social network sites along two Marxist themes – exploitation and alienation. It argues for a historical shift in the link between exploitation and alienation of audience labour, concurrent with the shift from mass media to social media. In the mass media, the capacity for exploitation of audience labour was quite limited while the alienation that such work created was high. In contrast, social media allows for the expansion and intensification of exploitation. Simultaneously, audience labour on social media – because it involves communication and sociability – also ameliorates alienation by allowing self-expression, authenticity, and relations with others. Moreover, the article argues that the political economy of social network sites is founded on a dialectical link between exploitation and alienation: in order to be de-alienated, Facebook users must communicate and socialize, thus exacerbating their exploitation. And vice-versa, in order for Facebook to exploit the work of its users, it must contribute to their de-alienation.

To provide information about Australian depression sites and the quality of their content; to identify possible indicators of the quality of site content; and determine the accessibility of Australian depression web sites. Cross-sectional survey of 15 Australian depression web sites. (i) Quality of treatment content (concordance of site information with evidence-based guidelines, number of evidence-based treatments recommended, discussion of other relevant issues, subjective rating of treatment content); (ii) potential quality indicators (conformity with DISCERN criteria, citation of scientific evidence); (iii) accessibility (search engine rank). Mean content quality scores were not high and site accessibility was poor. There was a consistent association between the quality-of-content measures and the DISCERN and scientific accountability scores. Search engine rank was not associated with content quality. The quality of information about depression on Australian websites could be improved. DISCERN may be a useful indicator of website quality, as may scientific accountability. The sites that received the highest quality-of-content ratings were beyondblue, BluePages, CRUfAD and InfraPsych.

A Ubiquitous Sensor Network Platform for Integrating Smart Devices into the Semantic Sensor Web

Science.gov (United States)

de Vera, David Díaz Pardo; Izquierdo, Álvaro Sigüenza; Vercher, Jesús Bernat; Gómez, Luis Alfonso Hernández

2014-01-01

Ongoing Sensor Web developments make a growing amount of heterogeneous sensor data available to smart devices. This is generating an increasing demand for homogeneous mechanisms to access, publish and share real-world information. This paper discusses, first, an architectural solution based on Next Generation Networks: a pilot Telco Ubiquitous Sensor Network (USN) Platform that embeds several OGC® Sensor Web services. This platform has already been deployed in large scale projects. Second, the USN-Platform is extended to explore a first approach to Semantic Sensor Web principles and technologies, so that smart devices can access Sensor Web data, allowing them also to share richer (semantically interpreted) information. An experimental scenario is presented: a smart car that consumes and produces real-world information which is integrated into the Semantic Sensor Web through a Telco USN-Platform. Performance tests revealed that observation publishing times with our experimental system were well within limits compatible with the adequate operation of smart safety assistance systems in vehicles. On the other hand, response times for complex queries on large repositories may be inappropriate for rapid reaction needs. PMID:24945678

to critically appraise the available literature and summarise the evidence relating to adolescent mothers' use of social networking sites in terms of any social support and social capital they may provide and to identify areas for future exploration. social networking sites have been demonstrated to provide social support to marginalised individuals and provide psycho-social benefits to members of such groups. Adolescent mothers are at risk of; social marginalisation; anxiety disorders and depressive symptoms; and poorer health and educational outcomes for their children. Social support has been shown to benefit adolescent mothers thus online mechanisms require consideration. a review of original research articles METHOD: key terms and Boolean operators identified research reports across a 20-year timeframe pertaining to the area of enquiry in: CINAHL, Cochrane Library, Medline, Scopus, ERIC, ProQuest, PsychINFO, Web of Science, Health Collection (Informit) and Google Scholar databases. Eight original research articles met the inclusion criteria for this review. studies demonstrate that adolescent mothers actively search for health information using the Internet and social networking sites, and that social support and social capital can be attributed to their use of specifically created online groups from within targeted health interventions. Use of a message board forum for pregnant and parenting adolescents also demonstrates elements of social support. There are no studies to date pertaining to adolescent mothers' use of globally accessible social networking sites in terms of social support provision and related outcomes. further investigation is warranted to explore the potential benefits of adolescent mothers' use of globally accessible social networking sites in terms of any social support provision and social capital they may provide.

The American Society for Surgery of the Hand (ASSH) Ethics and Professionalism Committee surveyed the ASSH membership regarding PRWs. We sent a 14-item questionnaire to 2,664 active ASSH members who practice in both private and academic settings in the United States. We received 312 responses, a 12% response incidence. More than 65% of the respondents had a slightly or highly unfavorable impression of these Web sites. Only 34% of respondents had ever updated or created a profile for PRWs, although 62% had observed inaccuracies in their profile. Almost 90% of respondents had not made any changes in their practice owing to comments or reviews. One-third of respondents had solicited favorable reviews from patients, and 3% of respondents have paid to improve their ratings. PRWs are going to become more prevalent, and more research is needed to fully understand the implications. There are several ethical implications that PRWs pose to practicing physicians. We contend that it is morally unsound to pay for good reviews. The recourse for physicians when an inaccurate and potentially libelous review has been written is unclear. Some physicians have required patients to sign a waiver preventing them from posting negative comments online. We propose the development of a task force to assess the professional, ethical, and legal implications of PRWs, including working with companies to improve accuracy of information, oversight, and feedback opportunities. It is expected that PRWs will play an increasing role in the future; it is unclear whether there will be a uniform reporting system, or whether these online ratings will influence referral patterns and/or quality improvement.

2016-06-01

Full Text Available In today’s business environment, there is no chance for a corporation to be succeeded simply by doing profit oriented business. Corporations are the living entities along with their stakeholders therefore corporations are expected to be responsive on the cultural, environmental and economic issues of society. Socially responsible programs that corporations execute would contribute the corporate image and reputation. Furthermore, these programs benefit both corporations and society. The aim of this study is to examine the presence and organization of information on corporate responsibility present on the corporate web sites of companies which are in the Capital top 500 list. We will choose the top 100 companies on the top 500 list. By using content analysis, identified corporate responsibility issues will be analyzed. In this study, the information given in the web sites of these top 100 companies will be analyzed. We will be examining how the information is organized, presented, and related to the corporate responsibilities.

Effects of organizational scheme and labeling on task performance in product-centered and user-centered retail Web sites.

Science.gov (United States)

Resnick, Marc L; Sanchez, Julian

2004-01-01

As companies increase the quantity of information they provide through their Web sites, it is critical that content is structured with an appropriate architecture. However, resource constraints often limit the ability of companies to apply all Web design principles completely. This study quantifies the effects of two major information architecture principles in a controlled study that isolates the incremental effects of organizational scheme and labeling on user performance and satisfaction. Sixty participants with a wide range of Internet and on-line shopping experience were recruited to complete a series of shopping tasks on a prototype retail shopping Web site. User-centered labels provided a significant benefit in performance and satisfaction over labels obtained through company-centered methods. User-centered organization did not result in improved performance except when the label quality was poor. Significant interactions suggest specific guidelines for allocating resources in Web site design. Applications of this research include the design of Web sites for any commercial application, particularly E-commerce.

Ramakrishnan, I V; Ashok, Vikas; Billah, Syed Masum

2017-07-01

People with vision impairments typically use screen readers to browse the Web. To facilitate non-visual browsing, web sites must be made accessible to screen readers, i.e., all the visible elements in the web site must be readable by the screen reader. But even if web sites are accessible, screen-reader users may not find them easy to use and/or easy to navigate. For example, they may not be able to locate the desired information without having to listen to a lot of irrelevant contents. These issues go beyond web accessibility and directly impact web usability. Several techniques have been reported in the accessibility literature for making the Web usable for screen reading. This paper is a review of these techniques. Interestingly, the review reveals that understanding the semantics of the web content is the overarching theme that drives these techniques for improving web usability.

Slater, Amy; Tiggemann, Marika; Hawkins, Kimberley; Werchon, Douglas

2012-04-01

The current study provides a comprehensive analysis of the content of advertisements on Web sites targeted at adolescents, with a particular focus on the female beauty ideal. Advertisements (N = 631) from 14 Web sites popular with adolescents were analyzed with respect to product advertised, characteristics of people presented, and emphasis on appearance and the thin beauty ideal. Although a wide variety of products were featured, advertisements for cosmetics and beauty products were the most frequent. Further, many of the products advertised (e.g., dating services, weight loss products, gambling games) might be considered inappropriate for the intended audience (i.e., teenagers) of the Web site. People who were a part of advertisements were generally female, young, thin, and attractive. Advertisements for games, weight loss products, and cosmetic and beauty products strongly focused on appearance and laid emphasis on the thin ideal. Like advertisements in mainstream media, advertising on the Internet perpetuates the stereotypical ideal of feminine beauty. Adolescents using the Internet are likely to be exposed to numerous advertisements that reinforce the importance of beauty and thinness, which could have a detrimental impact on how they feel about their bodies.

AIDS web sites face censorship under new rating schemes.

Science.gov (United States)

1997-08-22

The American Civil Liberties Union (ACLU) issued a position paper regarding the software industry's proposed rating standards that will block and rate information judged unsuitable for minors. Following the U.S. Supreme Court's overturning of the Communications Decency Act, a ruling that maintains a high level of free speech protection over the Internet, the software industry began examining mechanisms to rate online content. Legislators are considering criminal penalties for those who misrate a web page. These moves are seen as damaging to HIV/AIDS prevention and safe sex information web sites that utilize jargon, street language, and explicit diagrams to teach safe sex practices to a wide audience. It is noted that related ratings and censorships do not apply to print material.

2013-05-15

Internet-based learning programs provide people with massive health care information and self-help guidelines on improving their health. The advent of Web 2.0 and social networks renders significant flexibility to embedding highly interactive components, such as games, to foster learning processes. The effectiveness of game-based learning on social networks has not yet been fully evaluated. The aim of this study was to assess the effectiveness of a fully automated, Web-based, social network electronic game on enhancing mental health knowledge and problem-solving skills of young people. We investigated potential motivational constructs directly affecting the learning outcome. Gender differences in learning outcome and motivation were also examined. A pre/posttest design was used to evaluate the fully automated Web-based intervention. Participants, recruited from a closed online user group, self-assessed their mental health literacy and motivational constructs before and after completing the game within a 3-week period. The electronic game was designed according to cognitive-behavioral approaches. Completers and intent-to-treat analyses, using multiple imputation for missing data, were performed. Regression analysis with backward selection was employed when examining the relationship between knowledge enhancement and motivational constructs. The sample included 73 undergraduates (42 females) for completers analysis. The gaming approach was effective in enhancing young people's mental health literacy (d=0.65). The finding was also consistent with the intent-to-treat analysis, which included 127 undergraduates (75 females). No gender differences were found in learning outcome (P=.97). Intrinsic goal orientation was the primary factor in learning motivation, whereas test anxiety was successfully alleviated in the game setting. No gender differences were found on any learning motivation subscales (P>.10). We also found that participants' self-efficacy for learning and

Analysis of co-occurrence toponyms in web pages based on complex networks

Zhong, Xiang; Liu, Jiajun; Gao, Yong; Wu, Lun

2017-01-01

A large number of geographical toponyms exist in web pages and other documents, providing abundant geographical resources for GIS. It is very common for toponyms to co-occur in the same documents. To investigate these relations associated with geographic entities, a novel complex network model for co-occurrence toponyms is proposed. Then, 12 toponym co-occurrence networks are constructed from the toponym sets extracted from the People's Daily Paper documents of 2010. It is found that two toponyms have a high co-occurrence probability if they are at the same administrative level or if they possess a part-whole relationship. By applying complex network analysis methods to toponym co-occurrence networks, we find the following characteristics. (1) The navigation vertices of the co-occurrence networks can be found by degree centrality analysis. (2) The networks express strong cluster characteristics, and it takes only several steps to reach one vertex from another one, implying that the networks are small-world graphs. (3) The degree distribution satisfies the power law with an exponent of 1.7, so the networks are free-scale. (4) The networks are disassortative and have similar assortative modes, with assortative exponents of approximately 0.18 and assortative indexes less than 0. (5) The frequency of toponym co-occurrence is weakly negatively correlated with geographic distance, but more strongly negatively correlated with administrative hierarchical distance. Considering the toponym frequencies and co-occurrence relationships, a novel method based on link analysis is presented to extract the core toponyms from web pages. This method is suitable and effective for geographical information retrieval.

L Schlenkrich

2012-09-01

Full Text Available Social networking sites are extremely popular online destinations that offer users easy ways to build and maintain relationships with each other, and to disseminate information in an activity referred to as social networking. Students, lecturers, teachers, parents and businesses, in increasing numbers, use tools available on social networking sites to communicate with each other in a fast and cost-effective manner. The use of social networking sites to support educational initiatives has received much attention. However, the full potential of social network sites has yet to be achieved as users continue to strive for optimal ways of using these sites, as well as battle to overcome the negative characteristics (for example, privacy, security, governance, user behaviour, information quality of these sites. This paper proposes factors for successful use of social networking sites in higher educational institutions. These success factors need to be adopted by users in order to develop the positive aspects of social networking, while at the same time mitigating the negative characteristics. An initial set of factors for successful use of social networking sites, as well as measures to test successful use of social networking sites were derived from the literature. These factors were tested by means of an online survey of students at a university, the results of which informed the final factors for successful use of social networking sites. The factors enable users to overcome the negative characteristics associated with social networking sites. If used successfully, social networking sites can offer lecturers and students a useful tool with which to develop their relationship and contribute to their learning experience.

ProBiS-ligands: a web server for prediction of ligands by examination of protein binding sites.

Konc, Janez; Janežič, Dušanka

2014-07-01

The ProBiS-ligands web server predicts binding of ligands to a protein structure. Starting with a protein structure or binding site, ProBiS-ligands first identifies template proteins in the Protein Data Bank that share similar binding sites. Based on the superimpositions of the query protein and the similar binding sites found, the server then transposes the ligand structures from those sites to the query protein. Such ligand prediction supports many activities, e.g. drug repurposing. The ProBiS-ligands web server, an extension of the ProBiS web server, is open and free to all users at http://probis.cmm.ki.si/ligands. © The Author(s) 2014.

2016-12-01

To investigate online search activity of suicide-related words in South Korean adolescents through data mining of social media Web sites as the suicide rate in South Korea is one of the highest in the world. Out of more than 2.35 billion posts for 2 years from January 1, 2011 to December 31, 2012 on 163 social media Web sites in South Korea, 99,693 suicide-related documents were retrieved by Crawler and analyzed using text mining and opinion mining. These data were further combined with monthly employment rate, monthly rental prices index, monthly youth suicide rate, and monthly number of reported bully victims to fit multilevel models as well as structural equation models. The link from grade pressure to suicide risk showed the largest standardized path coefficient (beta = .357, p < .001) in structural models and a significant random effect (p < .01) in multilevel models. Depression was a partial mediator between suicide risk and grade pressure, low body image, victims of bullying, and concerns about disease. The largest total effect was observed in the grade pressure to depression to suicide risk. The multilevel models indicate about 27% of the variance in the daily suicide-related word search activity is explained by month-to-month variations. A lower employment rate, a higher rental prices index, and more bullying were associated with an increased suicide-related word search activity. Academic pressure appears to be the biggest contributor to Korean adolescents' suicide risk. Real-time suicide-related word search activity monitoring and response system needs to be developed.

Ekstrand, A. L.; Haderman, M.; Chan, A.; Dye, T.; White, J. E.; Parajon, G.

2015-12-01

DMS is an environmental Data Management System to manage, quality-control (QC), summarize, document chain-of-custody, and disseminate data from networks ranging in size from a few sites to thousands of sites, instruments, and sensors. The server-client desktop version of DMS is used by local and regional air quality agencies (including the Bay Area Air Quality Management District, the South Coast Air Quality Management District, and the California Air Resources Board), the EPA's AirNow Program, and the EPA's AirNow-International (AirNow-I) program, which offers countries the ability to run an AirNow-like system. As AirNow's core data processing engine, DMS ingests, QCs, and stores real-time data from over 30,000 active sensors at over 5,280 air quality and meteorological sites from over 130 air quality agencies across the United States. As part of the AirNow-I program, several instances of DMS are deployed in China, Mexico, and Taiwan. The U.S. Department of State's StateAir Program also uses DMS for five regions in China and plans to expand to other countries in the future. Recent development has begun to migrate DMS from an onsite desktop application to WebDMS, a web-based application designed to take advantage of cloud hosting and computing services to increase scalability and lower costs. WebDMS will continue to provide easy-to-use data analysis tools, such as time-series graphs, scatterplots, and wind- or pollution-rose diagrams, as well as allowing data to be exported to external systems such as the EPA's Air Quality System (AQS). WebDMS will also provide new GIS analysis features and a suite of web services through a RESTful web API. These changes will better meet air agency needs and allow for broader national and international use (for example, by the AirNow-I partners). We will talk about the challenges and advantages of migrating DMS to the web, modernizing the DMS user interface, and making it more cost-effective to enhance and maintain over time.

Grid-optimized Web 3D applications on wide area network

2008-08-01

Geographical information system has come into the Web Service times now. In this paper, Web3D applications have been developed based on our developed Gridjet platform, which provides a more effective solution for massive 3D geo-dataset sharing in distributed environments. Web3D services enabling web users could access the services as 3D scenes, virtual geographical environment and so on. However, Web3D services should be shared by thousands of essential users that inherently distributed on different geography locations. Large 3D geo-datasets need to be transferred to distributed clients via conventional HTTP, NFS and FTP protocols, which often encounters long waits and frustration in distributed wide area network environments. GridJet was used as the underlying engine between the Web 3D application node and geo-data server that utilizes a wide range of technologies including the one of paralleling the remote file access, which is a WAN/Grid-optimized protocol and provides "local-like" accesses to remote 3D geo-datasets. No change in the way of using software is required since the multi-streamed GridJet protocol remains fully compatible with existing IP infrastructures. Our recent progress includes a real-world test that Web3D applications as Google Earth over the GridJet protocol beats those over the classic ones by a factor of 2-7 where the transfer distance is over 10,000 km.

Dykstra, D.; Blomer, J.; Blumenfeld, B.; De Salvo, A.; Dewhurst, A.; Verguilov, V.

2017-10-01

All four of the LHC experiments depend on web proxies (that is, squids) at each grid site to support software distribution by the CernVM FileSystem (CVMFS). CMS and ATLAS also use web proxies for conditions data distributed through the Frontier Distributed Database caching system. ATLAS & CMS each have their own methods for their grid jobs to find out which web proxies to use for Frontier at each site, and CVMFS has a third method. Those diverse methods limit usability and flexibility, particularly for opportunistic use cases, where an experiment’s jobs are run at sites that do not primarily support that experiment. This paper describes a new Worldwide LHC Computing Grid (WLCG) system for discovering the addresses of web proxies. The system is based on an internet standard called Web Proxy Auto Discovery (WPAD). WPAD is in turn based on another standard called Proxy Auto Configuration (PAC). Both the Frontier and CVMFS clients support this standard. The input into the WLCG system comes from squids registered in the ATLAS Grid Information System (AGIS) and CMS SITECONF files, cross-checked with squids registered by sites in the Grid Configuration Database (GOCDB) and the OSG Information Management (OIM) system, and combined with some exceptions manually configured by people from ATLAS and CMS who operate WLCG Squid monitoring. WPAD servers at CERN respond to http requests from grid nodes all over the world with a PAC file that lists available web proxies, based on IP addresses matched from a database that contains the IP address ranges registered to organizations. Large grid sites are encouraged to supply their own WPAD web servers for more flexibility, to avoid being affected by short term long distance network outages, and to offload the WLCG WPAD servers at CERN. The CERN WPAD servers additionally support requests from jobs running at non-grid sites (particularly for LHC@Home) which they direct to the nearest publicly accessible web proxy servers. The responses

CONTEXTUAL DIFFERENCES IN THE DYNAMIC MEASUREMENT OF TRUST IN WEB SITES ACROSS DOMAINS

2012-12-01

Full Text Available The purpose of this study was to better understand user trust in web sites designed for different contexts; commerce, health and news. This research evaluated changes in trust ratings as users interacted with website elements. Differences in user trust ratings were observed between websites, which suggests that these changes in trust ratings are likely related to the website context. Therefore, people may develop different thresholds for trust based on concepts of usability, privacy, and content that are related to the website context. Finally, these results can also be used to inform the design of web sites to foster user trust in websites designed for different contexts.

Lindquist, K. G.; Newman, R. L.; Nayak, A.; Vernon, F. L.; Nelson, C.; Hansen, T. S.; Yuen-Wong, R.

2003-12-01

As near-real-time sensor grids become more widespread, and processing systems based on them become more powerful, summarizing the raw and derived information products and delivering them to the end user become increasingly important both for ongoing monitoring and as a platform for cross-disciplinary research. We have re-engineered the dbrecenteqs program, which was designed to express real-time earthquake databases into dynamic web pages, with several powerful new technologies. While the application is still most fully developed for seismic data, the infrastructure is extensible (and being extended) to create a real-time information architecture for numerous signal domains. This work provides a practical, lightweight approach suitable for individual seismic and sensor networks, which does not require a full 'web-services' implementation. Nevertheless, the technologies here are extensible to larger applications such as the Storage-Resource-Broker based VORB project. The technologies included in the new system blend real-time relational databases as a focus for processing and data handling; an XML->XSLT architecture as the core of the web mirroring; PHP extensions to Antelope (the environmental monitoring-system context adopted for RoadNET) in order to support complex, user-driven interactivity; and VRML output for expression of information as web-browsable three-dimensional worlds.

The Fulton County medical examiner (FCME) has an office web site which includes information about unidentified decedents and cases for which next of kin are being sought. Information about unidentified deceased and cases in need of next of kin has been posted on the FCME web site for 3 years and 1 year, respectively. FCME investigators and staff medical examiners were surveyed about the web site's usefulness for making identifications and locating next of kin. No cases were recalled in which the web site led to making an identification. Two cases were reported in which next of kin were located, and another case involved a missing person being ruled out as one of the decedents. The web site page is visited by agencies interested in missing and unidentified persons, and employees do find it useful for follow-up because information about all unidentified decedents is located and easily accessible, electronically, in a single location. Despite low yield in making identifications and locating next of kin, the UID web site is useful in some respects, and there is no compelling reason to discontinue its existence. It is proposed that UID pages on office web sites be divided into "hot" (less than 30 days, for example) and "warm" (31 days to 1 year, for example) cases and that cases older than a year be designated as "cold cases." It is conceivable that all unidentified deceased cases nationally could be placed on a single web site designed for such purposes, to remain in public access until identity is established and confirmed.

The Linking Probability of Deep Spider-Web Networks

We consider crossbar switching networks with base $b$ (that is, constructed from $b\\times b$ crossbar switches), scale $k$ (that is, with $b^k$ inputs, $b^k$ outputs and $b^k$ links between each consecutive pair of stages) and depth $l$ (that is, with $l$ stages). We assume that the crossbars are interconnected according to the spider-web pattern, whereby two diverging paths reconverge only after at least $k$ stages. We assume that each vertex is independently idle with probability $q$, the v...
