    Hypertension (HTN) is a prevalent and growing public health problem in the United States and worldwide. Video sharing Web sites such as YouTube could potentially influence patient behaviors via properties of interpersonal and mass media communication. We conducted this cross-sectional study to assess the accuracy and content of YouTube videos on HTN and understand how viewers interact with this online information. We analyzed 209 videos (31.57 hours) of which 63% were classified as useful, 33% as misleading, and 4% represented patient's personal experiences. Number of views per day and "likes" were significantly lower for useful videos. Approximately half the misleading videos contained product advertisements, 70% advocated unproven alternative treatments, and 91% targeted patients. Viewer engagement (number of views) was a poor predictor of usefulness and/or content whereas source of upload, and target audiences were good predictors of usefulness and/or content. Videos uploaded by university channels and/or professional organizations that targeted physicians had a 99.4% (P < .001) probability of being useful whereas videos uploaded by individuals with unknown credentials that targeted patients had a 21.2% (P < .001) probability of being useful. A majority of HTN-related videos on YouTube are useful. Viewer engagement is significantly higher with videos that contain misleading and/or erroneous information in comparison to videos that contain useful information.

    To assess the informational value, intention, source, and bias of videos related to orthodontics screened by the video-sharing Internet platform YouTube. YouTube (www.youtube.com) was scanned in July 2010 for orthodontics-related videos using an adequately defined search term. Each of the first 30 search results of the scan was categorized with the system-generated sorts "by relevance" and "most viewed" (total: 60). These were rated independently by three assessors, who completed a questionnaire for each video. The data were analyzed statistically using Friedman's test for dependent samples, Kendall's tau, and Fleiss's kappa. The YouTube scan produced 5140 results. There was a wide variety of information about orthodontics available on YouTube, and the highest proportion of videos was found to originate from orthodontic patients. These videos were also the most viewed ones. The informational content of most of the videos was generally judged to be low, with a rather poor to inadequate representation of the orthodontic profession, although a moderately pro-orthodontics stance prevailed. It was noticeable that the majority of contributions of orthodontists to YouTube constituted advertising. This tendency was not viewed positively by the majority of YouTube users, as was evident in the divergence in the proportions when sorting by "relevance" and "most viewed." In the light of the very large number of people using the Internet as their primary source of information, orthodontists should recognize the importance of YouTube and similar social media Web sites in the opinion-forming process, especially in the case of adolescents.

  5. Estimation of Web video multiplicity

    With ever more popularity of video web-publishing, many popular contents are being mirrored, reformatted, modified and republished, resulting in excessive content duplication. While such redundancy provides fault tolerance for continuous availability of information, it could potentially create problems for multimedia search engines in that the search results for a given query might become repetitious, and cluttered with a large number of duplicates. As such, developing techniques for detecting similarity and duplication is important to multimedia search engines. In addition, content providers might be interested in identifying duplicates of their content for legal, contractual or other business related reasons. In this paper, we propose an efficient algorithm called video signature to detect similar video sequences for large databases such as the web. The idea is to first form a 'signature' for each video sequence by selection a small number of its frames that are most similar to a number of randomly chosen seed images. Then the similarity between any tow video sequences can be reliably estimated by comparing their respective signatures. Using this method, we achieve 85 percent recall and precision ratios on a test database of 377 video sequences. As a proof of concept, we have applied our proposed algorithm to a collection of 1800 hours of video corresponding to around 45000 clips from the web. Our results indicate that, on average, every video in our collection from the web has around five similar copies.

    The internet is gaining importance in global wildlife trade and changing perceptions of threatened species. There is little data available to examine the impact that popular Web 2.0 sites play on public perceptions of threatened species. YouTube videos portraying wildlife allow us to quantify these perceptions. Focussing on a group of threatened and globally protected primates, slow lorises, we quantify public attitudes towards wildlife conservation by analysing 12,411 comments and associated data posted on a viral YouTube video 'tickling slow loris' over a 33-months period. In the initial months a quarter of commentators indicated wanting a loris as a pet, but as facts about their conservation and ecology became more prevalent this dropped significantly. Endorsements, where people were directed to the site by celebrities, resulted mostly in numerous neutral responses with few links to conservation or awareness. Two conservation-related events, linked to Wikipedia and the airing of a television documentary, led to an increase in awareness, and ultimately to the removal of the analysed video. Slow loris videos that have gone viral have introduced these primates to a large cross-section of society that would not normally come into contact with them. Analyses of webometric data posted on the internet allow us quickly to gauge societal sentiments. We showed a clear temporal change in some views expressed but without an apparent increase in knowledge about the conservation plight of the species, or the illegal nature of slow loris trade. Celebrity endorsement of videos showing protected wildlife increases visits to such sites, but does not educate about conservation issues. The strong desire of commentators to express their want for one as a pet demonstrates the need for Web 2.0 sites to provide a mechanism via which illegal animal material can be identified and policed.

    2015-12-01

    Full Text Available During the last years, video files showing different surgical procedures have become extremely available and popular on the internet. They are available on both free and unrestricted sites, as well as on dedicated sites which control the medical quality of the information. Honest presentation and a minimal video-editing to include information about the procedure are mandatory to achieve a product with a true educational value. The integration of the web-based video educational resources in the continuing medical information system seems to be limited and the true educational impact very difficult to assess. A review of the available literature dedicated on this subject shows that the main challenge is related to the human factor and not to the available technology.

    Due to the increasing user expectation on watching experience, moving web high quality video streaming content from the small screen in mobile devices to the larger TV screen has become popular. It is crucial to develop video quality metrics to measure the quality change for various devices or network conditions. In this paper, we propose an automated scoring system to quantify user satisfaction. We compare the quality of local videos with the videos transmitted to a TV. Four video quality metrics, namely Image Quality, Rendering Quality, Freeze Time Ratio and Rate of Freeze Events are used to measure video quality change during web content mirroring. To measure image quality and rendering quality, we compare the matched frames between the source video and the destination video using barcode tools. Freeze time ratio and rate of freeze events are measured after extracting video timestamps. Several user studies are conducted to evaluate the impact of each objective video quality metric on the subjective user watching experience.

    The BBC publishes large amounts of content online, as text, audio and video. As the amount of content grows, we need to make it easy for users to locate items of interest and to draw coherent journeys across them. In this chapter, we describe our use of Semantic Web technologies for achieving this goal. We focus in particular on three BBC Web sites: BBC Programmes, BBC Music and BBC Wildlife Finder, and how those Web sites effectively use the wider Web as their Content Management System.

    In order to promote NASA-wide educational outreach program to educate and inform the public of space exploration, NASA, at Kennedy Space Center, is seeking efficient ways to add more contents to the web by streaming audio/video files. This project proposes a high level overview of a framework for the creation, management, and scheduling of audio/video assets over the web. To support short-term goals, the prototype of a web-based tool is designed and demonstrated to automate the process of streaming audio/video files. The tool provides web-enabled users interfaces to manage video assets, create publishable schedules of video assets for streaming, and schedule the streaming events. These operations are performed on user-defined and system-derived metadata of audio/video assets stored in a relational database while the assets reside on separate repository. The prototype tool is designed using ColdFusion 5.0.

    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.

    In this paper, we describe a new telepresence system which enables a user to look around a virtualized real world easily in network environments. The proposed system includes omni-directional video viewers on web browsers and allows the user to look around the omni-directional video contents on the web browsers. The omni-directional video viewer is implemented as an Active-X program so that the user can install the viewer automatically only by opening the web site which contains the omni-directional video contents. The system allows many users at different sites to look around the scene just like an interactive TV using a multi-cast protocol without increasing the network traffic. This paper describes the implemented system and the experiments using live and stored video streams. In the experiment with stored video streams, the system uses an omni-directional multi-camera system for video capturing. We can look around high resolution and high quality video contents. In the experiment with live video streams, a car-mounted omni-directional camera acquires omni-directional video streams surrounding the car, running in an outdoor environment. The acquired video streams are transferred to the remote site through the wireless and wired network using multi-cast protocol. We can see the live video contents freely in arbitrary direction. In the both experiments, we have implemented a view-dependent presentation with a head-mounted display (HMD) and a gyro sensor for realizing more rich presence.

  5. Web-video-mining-supported workflow modeling for laparoscopic surgeries.

    2016-11-01

    As quality assurance is of strong concern in advanced surgeries, intelligent surgical systems are expected to have knowledge such as the knowledge of the surgical workflow model (SWM) to support their intuitive cooperation with surgeons. For generating a robust and reliable SWM, a large amount of training data is required. However, training data collected by physically recording surgery operations is often limited and data collection is time-consuming and labor-intensive, severely influencing knowledge scalability of the surgical systems. The objective of this research is to solve the knowledge scalability problem in surgical workflow modeling with a low cost and labor efficient way. A novel web-video-mining-supported surgical workflow modeling (webSWM) method is developed. A novel video quality analysis method based on topic analysis and sentiment analysis techniques is developed to select high-quality videos from abundant and noisy web videos. A statistical learning method is then used to build the workflow model based on the selected videos. To test the effectiveness of the webSWM method, 250 web videos were mined to generate a surgical workflow for the robotic cholecystectomy surgery. The generated workflow was evaluated by 4 web-retrieved videos and 4 operation-room-recorded videos, respectively. The evaluation results (video selection consistency n-index ≥0.60; surgical workflow matching degree ≥0.84) proved the effectiveness of the webSWM method in generating robust and reliable SWM knowledge by mining web videos. With the webSWM method, abundant web videos were selected and a reliable SWM was modeled in a short time with low labor cost. Satisfied performances in mining web videos and learning surgery-related knowledge show that the webSWM method is promising in scaling knowledge for intelligent surgical systems.

    In recent years, the task of event recognition from videos has attracted increasing interest in multimedia area. While most of the existing research was mainly focused on exploring visual cues to handle relatively small-granular events, it is difficult to directly analyze video content without any prior knowledge. Therefore, synthesizing both the visual and semantic analysis is a natural way for video event understanding. In this paper, we study the problem of Web video event recognition, where Web videos often describe large-granular events and carry limited textual information. Key challenges include how to accurately represent event semantics from incomplete textual information and how to effectively explore the correlation between visual and textual cues for video event understanding. We propose a novel framework to perform complex event recognition from Web videos. In order to compensate the insufficient expressive power of visual cues, we construct an event knowledge base by deeply mining semantic information from ubiquitous Web documents. This event knowledge base is capable of describing each event with comprehensive semantics. By utilizing this base, the textual cues for a video can be significantly enriched. Furthermore, we introduce a two-view adaptive regression model, which explores the intrinsic correlation between the visual and textual cues of the videos to learn reliable classifiers. Extensive experiments on two real-world video data sets show the effectiveness of our proposed framework and prove that the event knowledge base indeed helps improve the performance of Web video event recognition.

    1997-01-01

    We describe a visual information system prototype for searching for images and videos on the World-Wide Web. New visual information in the form of images, graphics, animations and videos is being published on the Web at an incredible rate. However, cataloging this visual data is beyond the capabilities of current text-based Web search engines. In this paper, we describe a complete system by which visual information on the Web is (1) collected by automated agents, (2) processed in both text and visual feature domains, (3) catalogued and (4) indexed for fast search and retrieval. We introduce an image and video search engine which utilizes both text-based navigation and content-based technology for searching visually through the catalogued images and videos. Finally, we provide an initial evaluation based upon the cataloging of over one half million images and videos collected from the Web.

  19. 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.

  3. Security scanning of Web sites at CERN

    CERN Multimedia

    IT Department

    2010-01-01

    As of early 2010, the CERN Computer Security Team will start regular scanning of all Web sites and Web applications at CERN, visible on the Internet, or on the General Purpose Network (office network). The goal of this scanning is to improve the quality of CERN Web sites. All deficits found will be reported by e-mail to the relevant Web site owners, and must be fixed in a timely manner. Web site owners may also request one-off scans of their Web site or Web application, by sending an e-mail to Computer.Security@cern.ch. These Web scans are designed to limit the impact on the scanned Web sites. Nevertheless, in very rare cases scans may cause undesired side-effects, e.g. generate a large number of log entries, or cause particularly badly designed or less robust Web applications to crash. If a Web site is affected by these security scans, it will also be susceptible to any more aggressive scan that can be performed any time by a malicious attacker. Such Web applications should be fixed, and also additionally...

  6. Web-based Video Annotation and its Applications

    Science.gov (United States)

    Yamamoto, Daisuke; Nagao, Katashi

    In this paper, we developed a Web-based video annotation system, named iVAS (intelligent Video Annotation Server). Audiences can associate any video content on the Internet with annotations. The system analyzes video content in order to acquire cut/shot information and color histograms. And it also automatically generates a Web page for editing annotations. Then, audiences can create annotation data by two methods. The first one helps the users to create text data such as person/object names, scene descriptions, and comments interactively. The second method facilitates the users associating any video fragments with their subjective impression by just clicking a mouse button. The generated annotation data are accumulated and managed by an XML database connected with iVAS. We also developed some application systems based on annotations such as video retrieval, video simplification, and video-content-based community support. One of the major advantages of our approach is easy integration of hand-coded and automatically-generated (such as color histograms and cut/shot information) annotations. Additionally, since our annotation system is open for public, we must consider some reliability or correctness of annotation data. We also developed an automatic evaluation method of annotation reliability using the users' feedback. In the future, these fundamental technologies will contribute to the formation of new communities centered around video content.

  9. Improving Web-Based Student Learning Through Online Video Demonstrations

    Science.gov (United States)

    Miller, Scott; Redman, S.

    2010-01-01

    Students in online courses continue to lag their peers in comparable face-to-face (F2F) courses (Ury 2004, Slater & Jones 2004). A meta-study of web-based vs. classroom instruction by Sitzmann et al (2006) discovered that the degree of learner control positively influences the effectiveness of instruction: students do better when they are in control of their own learning. In particular, web-based courses are more effective when they incorporate a larger variety of instructional methods. To address this need, we developed a series of online videos to demonstrate various astronomical concepts and provided them to students enrolled in an online introductory astronomy course at Penn State University. We found that the online students performed worse than the F2F students on questions unrelated to the videos (t = -2.84), but that the online students who watched the videos performed better than the F2F students on related examination questions (t = 2.11). We also found that the online students who watched the videos performed significantly better than those who did not (t = 3.43). While the videos in general proved helpful, some videos were more helpful than others. We will discuss our thoughts on why this might be, and future plans to improve upon this study. These videos are freely available on iTunesU, YouTube, and Google Video.

    The Princeton Plasma Physics Laboratory in collaboration with teachers and students has developed a variety of educational outreach activities to demonstrate basic physical science principles using a variety of instructive and entertaining science demonstrations at elementary, middle and high school levels. A new effort has been initiated to demonstrate this material using web based videos. This can be a resource for the teacher, parent or student. In addition, the video is coupled to web-based lesson plans for the educator. The goal of these videos and lesson plans is to create enthusiasm and stimulate curiosity among students and teachers, showing them that science is interesting, fun, and within their grasp. The first video demonstrates a number of activities one can accomplish using a half-coated fluorescent tube. Additional demonstrations will be added over time.

    Amsbary, Jonathan Howard; Powell, Larry

    2003-08-01

    This study investigated the effect of first-person and third-person perceptions of web site information. Responses from a telephone survey of 226 participants in a stratified random sample indicated that (1) most participants had higher evaluations for television news than for news received on the Internet; (2) a third-person effect was present in that most respondents generally thought that other people found the Internet easier to use than they did, and that other people were more likely to believe Internet information and trust the sources of Internet information than they would. Also, (3), evaluations of information on a particular web site could be increased by providing links to other web sites on the same topic. Perhaps links to other web sites may serve as either a "referencing" function or a social confirmation function to increase evaluations of web site information.

    Wallin, Wendy S

    2009-11-01

    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.

    Once a healthcare organization has decided to establish a Web site on the Internet, it must next determine its implementation strategy, based on a full understanding of the goals of the site and the range of Web content and service offerings available in the marketplace. Although some organizations may choose to develop and maintain a Web site using exclusively in-house resources, most healthcare organizations will find that they can minimize the costs associated with this effort by making judicious use of outsourcing services. Whichever approach is used, it is important that financial managers charged with allocating resources for Web-site development and maintenance understand the implications, including relative financial impact, of key issues and options.

    2004-08-01

    To assure a smooth transition to their new work environment, rotating students and housestaff require detailed orientations to the physical layout and operations of the emergency department. Although such orientations are useful for new staff members, they represent a significant time commitment for the faculty members charged with this task. To address this issue, the authors developed a series of short instructional videos that provide a comprehensive and consistent method of emergency department orientation. The videos are viewed through Web-based streaming technology that allows learners to complete the orientation process from any computer with Internet access before their first shift. This report describes the stepwise process used to produce these videos and discusses the potential benefits of converting to an Internet-based orientation system.

    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

    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.

    2016-03-01

    Internet video sharing sites allow the free dissemination of educational material. This study investigated the quality and educational content of videos of eye movement disorders posted on such sites. Educational neurological eye movement videos were identified by entering the titles of the eye movement abnormality into the search boxes of the video sharing sites. Also, suggested links were followed from each video. The number of views, likes, and dislikes for each video were recorded. The videos were then rated for their picture and sound quality. Their educational value was assessed according to whether the video included a description of the eye movement abnormality, the anatomical location of the lesion (if appropriate), and the underlying diagnosis. Three hundred fifty-four of these videos were found on YouTube and Vimeo. There was a mean of 6,443 views per video (range, 1-195,957). One hundred nineteen (33.6%) had no form of commentary about the eye movement disorder shown apart from the title. Forty-seven (13.3%) contained errors in the title or in the text. Eighty (22.6%) had excellent educational value by describing the eye movement abnormality, the anatomical location of the lesion, and the underlying diagnosis. Of these, 30 also had good picture and sound quality. The videos with excellent educational value had a mean of 9.84 "likes" per video compared with 2.37 for those videos without a commentary (P educational value with good picture and sound quality had a mean of 10.23 "likes" per video (P = 0.004 vs videos with no commentary). There was no significant difference in the mean number of "dislikes" between those videos that had no commentary or which contained errors and those with excellent educational value. There are a large number of eye movement videos freely available on these sites; however, due to the lack of peer review, a significant number have poor educational value due to having no commentary or containing errors. The number of "likes

    2012-04-01

    A HTTP based video transmission system has been built upon the p2p(peer to peer) network structure utilizing the Java technologies. This makes the video monitoring available to any host which has been connected to the World Wide Web in any method, including those hosts behind firewalls or in isolated sub-networking. In order to achieve this, a video source peer has been developed, together with the client video playback peer. The video source peer can respond to the video stream request in HTTP protocol. HTTP based pipe communication model is developed to speeding the transmission of video stream data, which has been encoded into fragments using the JPEG codec. To make the system feasible in conveying video streams between arbitrary peers on the web, a HTTP protocol based relay peer is implemented as well. This video monitoring system has been applied in a tele-robotic system as a visual feedback to the operator.

    To assess the content of food industry Web sites targeting children by describing strategies used to prolong their visits and foster brand loyalty; and to document health-promoting messages on these Web sites. A content analysis was conducted of Web sites advertised on 2 children's networks, Cartoon Network and Nickelodeon. A total of 290 Web pages and 247 unique games on 19 Internet sites were examined. Games, found on 81% of Web sites, were the most predominant promotion strategy used. All games had at least 1 brand identifier, with logos being most frequently used. On average Web sites contained 1 "healthful" message for every 45 exposures to brand identifiers. Food companies use Web sites to extend their television advertising to promote brand loyalty among children. These sites almost exclusively promoted food items high in sugar and fat. Health professionals need to monitor food industry marketing practices used in "new media." Published by Elsevier Inc.

    Science.gov (United States)

    Samora, Julie Balch; Lifchez, Scott D; Blazar, Philip E

    2016-01-01

    To understand the ethical and professional implications of physician behavior changes secondary to online physician-rating Web sites (PRWs). 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.

  16. 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

    Science.gov (United States)

    Fajardo, Inmaculada; Parra, Elena; Cañas, José J

    2010-01-01

    The efficacy of video-based sign language (SL) navigation aids to improve Web search for Deaf Signers was tested by two experiments. Experiment 1 compared 2 navigation aids based on text hyperlinks linked to embedded SL videos, which differed in the spatial contiguity between the text hyperlink and SL video (contiguous vs. distant). Deaf Signers' performance was similar in Web search using both aids, but a positive correlation between their word categorization abilities and search efficiency appeared in the distant condition. In Experiment 2, the contiguous condition was compared with a text-only hyperlink condition. Deaf Signers became less disorientated (used shorter paths to find the target) in the text plus SL condition than in the text-only condition. In addition, the positive correlation between word categorization abilities and search only appeared in the text-only condition. These findings suggest that SL videos added to text hyperlinks improve Web search efficiency for Deaf Signers.

    Paulus, Yannis M; Thompson, Noel P

    2012-06-01

    We have devised an inexpensive, web-based tele-ultrasound system using commercially-available video streaming equipment. We examined the spatial and grey scale resolution, and the delay time of the system. The receiving PC was tested at various distances from the transmitting site, from 3.2 km to 4828 km. Standard resolution targets and echocardiography movie strips recorded on DVDs were used to assess the image quality. A qualitative assessment was made by an expert sonographer. As the distance between the transmitter and the receiver increased, the scan smoothness decreased and the delay increased. At a distance of 3.2 km the delay was 2-3 s, and at 4828 km it was 10-15 s. The delay was short enough to allow realtime guidance of the scanning technician by telephone. The system allows inexpensive, readily available, realtime tele-ultrasonography.

    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.

    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.

    Full Text Available Video surveillance system (VSS is an monitoring system based-on IP-camera. VSS implemented in live streaming and serves to observe and monitor a site remotely. Typically, IP- camera in the VSS has a management software application. However, for ad hoc applications, where the user wants to manage VSS independently, application management software has become ineffective. In the IP-camera installation spread over a large area, an administrator would be difficult to describe the location of the IP-camera. In addition, monitoring an area of IP- Camera will also become more difficult. By looking at some of the flaws in VSS, this paper has proposed a VSS application for easy monitoring of each IP Camera. Applications that have been proposed to integrate the concept of web-based geographical information system with the Google Maps API (Web-GIS.

    The purpose of this study was to explore and describe content related to pacifier use on parenting Web sites. Sixteen parenting Web sites met the inclusion criteria of the study. Two checklists were used to evaluate and describe different aspects of the Web sites. The first checklist provided a quality assessment of the Web sites. The second checklist was constructed to identify content categories of pacifier use. The majority of sites met quality assessment criteria. Eleven content categories regarding pacifier use were identified. Nine of the 16 sites contained eight or more of the 11 content areas. The most common types of Web pages containing pacifier information included pacifier specific (articles), questions and answer pages, and related content pages. Most of the parenting Web sites met the quality measures for online information. The content categories reflected the current controversies and information regarding pacifier use found in the expert literature. The findings of this study suggest the need to establish pacifier recommendations in the United States to guide parents and health care providers with decision making.

    Pazzani, M.; Muramatsu, J.; Billsus, D. [Univ. of California, Irvine, CA (United States)

    1996-12-31

    We describe Syskill & Webert, a software agent that learns to rate pages on the World Wide Web (WWW), deciding what pages might interest a user. The user rates explored pages on a three point scale, and Syskill & Webert learns a user profile by analyzing the information on each page. The user profile can be used in two ways. First, it can be used to suggest which links a user would be interested in exploring. Second, it can be used to construct a LYCOS query to find pages that would interest a user. We compare six different algorithms from machine learning and information retrieval on this task. We find that the naive Bayesian classifier offers several advantages over other learning algorithms on this task. Furthermore, we find that an initial portion of a web page is sufficient for making predictions on its interestingness substantially reducing the amount of network transmission required to make predictions.

    2004-06-21

    The World Wide Web (WWW) has become an increasingly essential resource for health information consumers. The ability to obtain accurate medical information online quickly, conveniently and privately provides health consumers with the opportunity to make informed decisions and participate actively in their personal care. Little is known, however, about whether the content of this online health information is equally accessible to people with disabilities who must rely on special devices or technologies to process online information due to their visual, hearing, mobility, or cognitive limitations. To construct a framework for an automated Web accessibility evaluation; to evaluate the state of accessibility of consumer health information Web sites; and to investigate the possible relationships between accessibility and other features of the Web sites, including function, popularity and importance. We carried out a cross-sectional study of the state of accessibility of health information Web sites to people with disabilities. We selected 108 consumer health information Web sites from the directory service of a Web search engine. A measurement framework was constructed to automatically measure the level of Web Accessibility Barriers (WAB) of Web sites following Web accessibility specifications. We investigated whether there was a difference between WAB scores across various functional categories of the Web sites, and also evaluated the correlation between the WAB and Alexa traffic rank and Google Page Rank of the Web sites. We found that none of the Web sites we looked at are completely accessible to people with disabilities, i.e., there were no sites that had no violation of Web accessibility rules. However, governmental and educational health information Web sites do exhibit better Web accessibility than the other categories of Web sites (P health information Web sites shows that no Web site scrupulously abides by Web accessibility specifications, even for entities

    Health care professionals, trainees, and patients use the Internet extensively. Editable Web sites may contain inaccurate, incomplete, and/or outdated information that may mislead the public's perception of the topic. To evaluate the editable, online descriptions of clinical pharmacy and pharmacist and attempt to improve their accuracy. The authors identified key areas within clinical pharmacy to evaluate for accuracy and appropriateness on the Internet. Current descriptions that were reviewed on public domain Web sites included: (1) clinical pharmacy and the clinical pharmacist, (2) pharmacy education, (3) clinical pharmacy and development and provision for reimbursement, (4) clinical pharmacists and advanced specialty certifications/training opportunities, (5) pharmacists and advocacy, and (6) clinical pharmacists and interdisciplinary/interprofessional content. The authors assessed each content area to determine accuracy and prioritized the need for updating, when applicable, to achieve consistency in descriptions and relevancy. The authors found that Wikipedia, a public domain that allows users to update, was consistently the most common Web site produced in search results. The authors' evaluation resulted in the creation or revision of 14 Wikipedia Web pages. However, rejection of 3 proposed newly created Web pages affected the authors' ability to address identified content areas with deficiencies and/or inaccuracies. Through assessing and updating editable Web sites, the authors strengthened the online representation of clinical pharmacy in a clear, cohesive, and accurate manner. However, ongoing assessments of the Internet are continually needed to ensure accuracy and appropriateness.

  2. Developing Exhibit-based, Interactive Web Sites to Communicate Science

    Dusenbery, P. B.; Harold, J.

    2003-12-01

    New technologies are transforming the Web from a static medium to an interactive environment with tremendous potential for informal education and inquiry-based investigations. ASTC, the trade association of science museums, gave its 2000 innovation award to the Exploratorium's Web page rather than a physical exhibit. The increased power of the Web as an informal learning tool is partly the result of technologies (such as Java, Flash and Shockwave) that allow the development of inquiry-based, interactive experiences. Web site visitors can now "learn science by doing science." This report features two online projects funded by NSF and NASA: MarsQuest Online and the Space Weather Center. TERC, the Space Science Institute, and NASA's Jet Propulsion Laboratory are developing MarsQuest Online, an interactive, exploration-based Web site that extends the reach and scope of the MarsQuest exhibit. The Space Weather Center Web site is based on the Space Weather Center exhibit that was developed in partnership with scientists and educators at NASA/GSFC. Both exhibits represent a tremendous, collaborative effort by scientists, educators, and designers to communicate the essentials of Mars science and space weather to the public. As such, the graphics, text, and story developed for the exhibits represent a valuable resource that will provide the framework and base content for the public site. Given that framework, the Web sites can then expand both the content and audience of the exhibits in key ways. In particular, the sites will 1) extend the reach of the exhibit by making it available online, 2) extend the scope of the exhibit, linking to the latest imagery and results from ground and space-based missions, and 3) provide support and follow-up for the exhibit education programs, while making materials available to more teachers, parents, and museum educators and docents.

  3. Taking a traditional web site to patient portal technology.

    Labow, Kimberly

    2010-01-01

    In this era of consumer-driven healthcare, consumers (your current and potential patients) seek healthcare information on the Internet. If your practice doesn't have a Web site, or has one that's static and uninformative, you won't be found, and the patient will move on to the next practice Web site. Why? Because only the most graphically appealing, informative, and patient-centered Web sites will drive patients to your practice. Patients are demanding improved communication with their physician. A practice Web site is a start, but the adoption of a fully functional, interactive Web site with patient portal solutions will not only improve patient-to-provider relationships but will also give the patient access to your practice from anywhere, at any time of the day. Furthermore, these solutions can help practices increase efficiencies and revenue, while reducing operating costs. With the American Recovery and Reinvestment Act of 2009 and other incentives for healthcare information technology adoption, the time is right for your practice to consider implementing technology that will bring considerable value to your practice and also increase patient satisfaction.

  4. Changing Behaviors: Market Transformation Web Sites as Online Narrative

    2008-01-01

    This research paper explores the communicative practice of designing web sites to accelerate the market adoption of energy-efficient and renewable energy technologies within the U.S. home building industry. In today's world, the Internet is increasingly used as a communication tool in market transformation efforts. By studying the practice of web site design through the lens of grounded practical theory this paper develops a normative ideal that can be used to guide and contribute to the conduct, criticism, and increased effectiveness of this practice. Research results are derived from an ethnographic study of the evaluation and judging of web sites developed by the twenty teams competing in the 2007 Solar Decathlon and a rhetorical analysis of the top scoring web sites. The Solar Decathlon is a national competition for universities and colleges to design, build, and operate the most efficient, affordable, and livable solar-powered home. This paper identifies the primary characteristics that the jurors found essential to an effective market transformation web site, and proposes that a narrative paradigm can be best used to construct a normative model of this practice within this context.

    2015-01-01

    Videos, memes and images of pet slow lorises have become increasingly popular on the Internet. Although some video sites allow viewers to tag material as 'animal cruelty', no site has yet acknowledged the presence of cruelty in slow loris videos. We examined 100 online videos to assess whether they violated the 'five freedoms' of animal welfare and whether presence or absence of these conditions contributed to the number of thumbs up and views received by the videos. We found that all 100 videos showed at least 1 condition known as negative for lorises, indicating absence of the necessary freedom; 4% showed only 1 condition, but in nearly one third (31.3%) all 5 chosen criteria were present, including human contact (57%), daylight (87%), signs of stress/ill health (53%), unnatural environment (91%) and isolation from conspecifics (77%). The public were more likely to like videos where a slow loris was kept in the light or displayed signs of stress. Recent work on primates has shown that imagery of primates in a human context can cause viewers to perceive them as less threatened. Prevalence of a positive public opinion of such videos is a real threat towards awareness of the conservation crisis faced by slow lorises. © 2016 S. Karger AG, Basel.

    A social networking Web site, Facebook, was used to deliver long-term sport psychology consultation services to student-athletes (i.e., soccer players) in 30- to 60-min weekly sessions. Additional short-term team building, group cohesion, communication, anger management, injury rehabilitation, mental toughness, commitment, and leadership workshops were provided. Cohesion and overall relationships between both the student-athletes and the sport psychology consultants benefited from this process. Social networking Web sites offer a practical way of providing sport psychology consulting services that does not require use of major resources. (c) 2012 APA, all rights reserved.

    Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but unfortunately there are no guidelines for annotating these videos or agreed methods to measure the educational content and the safety of the procedure presented. Aim of this study is to systematically search the World Wide Web to determine the availability of laparoscopic colorectal surgery videos and to objectively establish their potential training value. A search for laparoscopic right hemicolectomy videos was performed on the three most used English language web search engines Google.com, Bing.com, and Yahoo.com; moreover, a survey among 25 local trainees was performed to identify additional websites for inclusion. All laparoscopic right hemicolectomy videos with an English language title were included. Videos of open surgery, single incision laparoscopic surgery, robotic, and hand-assisted surgery were excluded. The safety of the demonstrated procedure was assessed with a validated competency assessment tool specifically designed for laparoscopic colorectal surgery and data on the educational content of the video were extracted. Thirty-one websites were identified and 182 surgical videos were included. One hundred and seventy-three videos (95%) detailed the year of publication; this demonstrated a significant increase in the number of videos published per year from 2009. Characteristics of the patient were rarely presented, only 10 videos (5.4%) reported operating time and only 6 videos (3.2%) reported 30-day morbidity; 34 videos (18.6%) underwent a peer-review process prior to publication. Formal case presentation, the presence of audio narration, the use of diagrams, and snapshots and a step-by-step approach are all characteristics of peer-reviewed videos but no significant difference was found in the safety of the procedure. Laparoscopic videos can be a useful adjunct to operative training. There is a large and increasing amount of

    Leila R. Lax

    2011-09-01

    Full Text Available The cultural, legal and ethical aspects of medical practice in Canada can be problematic for International Medical Graduates (IMGs to access and learn. The professional behaviours that depend on effective communication often challenge IMGs as they attempt to enter the Canadian medical system. The Communication and Cultural Competence Program provides a complex interactive web-based environment in which IMGs can learn and practice skills required to navigate these specific elements of medical practice. The educational design of this web site is based on the theory of knowledge building (Scardamalia & Bereiter, 2003. This paper examines how video simulation is used on the web site to support this design. Experiential simulation pedagogy, typically used in high-fidelity face-to-face encounters, is analyzed. Strategies to translate this pedagogy to an e-learning format to operationalize authentic knowledge building are described. Commentaries replace live facilitation and a communication tool, the Observation Guide, allows learners to participate in the simulation. This examination provides insight into the complexity involved in creating on-line resources that extend beyond clinical content repositories, illustrating the potential for web-based programs to provide reflective and recursive learning. A wide skill set with a broad base of support was necessary to create a virtual environment with depth and authenticity. Translating the process from live simulation to a mid-fidelity digital video format allowed for deeper understanding of how the unique skills of experienced simulators impact the educational process. This multi-dimensional e-learning platform has potential for teaching complex skills in medical programs.Les médecins diplômés à l’étranger (MDE peuvent avoir des difficultés à accéder aux aspects culturels, légaux et éthiques de la pratique médicale au Canada et à les apprendre.

    Many general surgical residency programs lack a formal international component. We hypothesized that most surgery programs do not have international training or do not provide the information to prospective applicants regarding electives or programs in an easily accessible manner via Web-based resources. Individual general surgery program Web sites and the American College of Surgeons residency tool were used to identify 239 residencies. The homepages were examined for specific mention of international or global health programs. Ease of access was also considered. Global surgery specific pages or centers were noted. Programs were assessed for length of rotation, presence of research component, and mention of benefits to residents and respective institution. Of 239 programs, 24 (10%) mentioned international experiences on their home page and 42 (18%) contained information about global surgery. Of those with information available, 69% were easily accessible. Academic programs were more likely than independent programs to have information about international opportunities on their home page (13.7% versus 4.0%, P = 0.006) and more likely to have a dedicated program or pathway Web site (18.8% versus 2.0%, P Web sites. Benefits to high-income country residents were discussed more than benefits to low- and middle-income country residents (57% versus 17%). General surgery residency programs do not effectively communicate international opportunities for prospective residents through Web-based resources and should seriously consider integrating international options into their curriculum and better present them on department Web sites.

    To design a questionnaire to evaluate compliance with quality criteria on health web sites and to analyse its reliability. A descriptive study on the reliability of a questionnaire. Twenty web sites on health topics. Internet. The questionnaire was based on analysis of content of the criteria of the e-Europe 2002 code of conduct, comparing these with the criteria underlying the AMA, the Summit code and the e-Health Code of Ethics regulations and current directives. The dimensions studied were transparency, absence of conflicts of interest, authorship, data protection, updating, accountability, and accessibility. A preliminary questionnaire was drawn up for a pilot test conducted by 3 researchers for 20 web sites, its reliability was appraised, adjustments were made and the definitive questionnaire was designed. Reliability was evaluated again for 26 web sites evaluated by 3 researchers. To evaluate concordance in the answers of the participants, Cohen's Kappa index with a 95% confidence level was used. All the quality directives of e-Europe 2002, the European regulations and relevant points from other questionnaires were included in the questionnaire designed. Reliability was acceptable (kappa > or = 0.60) for 12 of the 18 quality criteria included. The least concordant aspects of the questionnaire were information update (kappa = 0.310) and accessibility (search for contents and access for persons with disability). Reliability of the questionnaire designed was acceptable.

    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.

    Human-activity recognition is one of the most challenging problems in computer vision. Researchers from around the world have tried to solve this problem and have come a long way in recognizing simple motions and atomic activities. As the computer vision community heads toward fully recognizing human activities, a challenging and labeled dataset is needed. To respond to that need, we collected a dataset of realistic scenarios in a multi-camera network environment (VideoWeb) involving multiple persons performing dozens of different repetitive and non-repetitive activities. This chapter describes the details of the dataset. We believe that this VideoWeb Activities dataset is unique and it is one of the most challenging datasets available today. The dataset is publicly available online at http://vwdata.ee.ucr.edu/ along with the data annotation.

  1. Action and Event Recognition in Videos by Learning From Heterogeneous Web Sources.

    Science.gov (United States)

    Niu, Li; Xu, Xinxing; Chen, Lin; Duan, Lixin; Xu, Dong

    2017-06-01

    In this paper, we propose new approaches for action and event recognition by leveraging a large number of freely available Web videos (e.g., from Flickr video search engine) and Web images (e.g., from Bing and Google image search engines). We address this problem by formulating it as a new multi-domain adaptation problem, in which heterogeneous Web sources are provided. Specifically, we are given different types of visual features (e.g., the DeCAF features from Bing/Google images and the trajectory-based features from Flickr videos) from heterogeneous source domains and all types of visual features from the target domain. Considering the target domain is more relevant to some source domains, we propose a new approach named multi-domain adaptation with heterogeneous sources (MDA-HS) to effectively make use of the heterogeneous sources. In MDA-HS, we simultaneously seek for the optimal weights of multiple source domains, infer the labels of target domain samples, and learn an optimal target classifier. Moreover, as textual descriptions are often available for both Web videos and images, we propose a novel approach called MDA-HS using privileged information (MDA-HS+) to effectively incorporate the valuable textual information into our MDA-HS method, based on the recent learning using privileged information paradigm. MDA-HS+ can be further extended by using a new elastic-net-like regularization. We solve our MDA-HS and MDA-HS+ methods by using the cutting-plane algorithm, in which a multiple kernel learning problem is derived and solved. Extensive experiments on three benchmark data sets demonstrate that our proposed approaches are effective for action and event recognition without requiring any labeled samples from the target domain.

    Assessment of clinical competencies by direct observation is problematic for two main reasons the identity of the examinee influences the assessment scores, and direct observation demands experts at the exact location and the exact time. Recording the performance can overcome these problems......; however, managing video recordings and assessment sheets is troublesome and may lead to missing or incorrect data. Currently, no existing software solution can provide a local solution for the management of videos and assessments but this is necessary as assessment scores are confidential information......, and access to this information should be restricted to select personnel. A local software solution may also ease the need for customization to local needs and integration into existing user databases or project management software.

    Enayati, Moein; Banerjee, Tanvi; Popescu, Mihail; Skubic, Marjorie; Rantz, Marilyn

    2014-01-01

    The purpose of this study was to implement a web based application to provide the ability to rewind and review depth videos captured in hospital rooms to investigate the event chains that led to patient's fall at a specific time. In this research, Kinect depth images are being used to capture shadow-like images of the patient and their room to resolve concerns about patients' privacy. As a result of our previous research, a fall detection system has been developed and installed in hospital rooms, and fall alarms are generated if any falls are detected by the system. Then nurses will go through the stored depth videos to investigate for possible injury as well as the reasons and events that may have caused the patient's fall to prevent future occurrences. This paper proposes a novel web application to ease the process of search and reviewing the videos by means of new visualization techniques to highlight video frames that contain potential risk of fall based on our previous research.

  6. A Unified Framework for Tracking Based Text Detection and Recognition from Web Videos.

    2017-04-12

    Video text extraction plays an important role for multimedia understanding and retrieval. Most previous research efforts are conducted within individual frames. A few of recent methods, which pay attention to text tracking using multiple frames, however, do not effectively mine the relations among text detection, tracking and recognition. In this paper, we propose a generic Bayesian-based framework of Tracking based Text Detection And Recognition (T2DAR) from web videos for embedded captions, which is composed of three major components, i.e., text tracking, tracking based text detection, and tracking based text recognition. In this unified framework, text tracking is first conducted by tracking-by-detection. Tracking trajectories are then revised and refined with detection or recognition results. Text detection or recognition is finally improved with multi-frame integration. Moreover, a challenging video text (embedded caption text) database (USTB-VidTEXT) is constructed and publicly available. A variety of experiments on this dataset verify that our proposed approach largely improves the performance of text detection and recognition from web videos.

    2012-04-01

    More and more seagoing scientific expeditions use video-controlled research platforms such as Remote Operating Vehicles (ROV), Autonomous Underwater Vehicles (AUV), and towed camera systems. These produce many hours of video material which contains detailed and scientifically highly valuable footage of the biological, chemical, geological, and physical aspects of the oceans. Many of the videos contain unique observations of unknown life-forms which are rare, and which cannot be sampled and studied otherwise. To make such video material online accessible and to create a collaborative annotation environment the "Video Annotation and processing platform" (V-App) was developed. A first solely web-based installation for ROV videos is setup at the German Center for Marine Environmental Sciences (available at http://videolib.marum.de). It allows users to search and watch videos with a standard web browser based on the HTML5 standard. Moreover, V-App implements social web technologies allowing a distributed world-wide scientific community to collaboratively annotate videos anywhere at any time. It has several features fully implemented among which are: • User login system for fine grained permission and access control • Video watching • Video search using keywords, geographic position, depth and time range and any combination thereof • Video annotation organised in themes (tracks) such as biology and geology among others in standard or full screen mode • Annotation keyword management: Administrative users can add, delete, and update single keywords for annotation or upload sets of keywords from Excel-sheets • Download of products for scientific use This unique web application system helps making costly ROV videos online available (estimated cost range between 5.000 - 10.000 Euros per hour depending on the combination of ship and ROV). Moreover, with this system each expert annotation adds instantaneous available and valuable knowledge to otherwise uncharted

    The study purpose was to determine the predictors of watching most of a Web-based streaming video and whether data characteristics differed for those watching most or only part of the video. A convenience sample of 650 students (349 Asian Americans and 301 non-Hispanic whites) was recruited from a public university in the United States. Study participants were asked to view a 27-minute suicide awareness streaming video and to complete online questionnaires. Early data monitoring showed many, but not all, watched most of the video. We added software controls to facilitate video completion and defined times for a video completion group (≥26 minutes) and video noncompletion (video noncompletion group, the video completion group included more females, undergraduates, and Asian Americans, and had higher individualistic orientation and more correct manipulation check answers. The video noncompletion group skipped items in a purposeful manner, showed less interest in the video, and spent less time completing questionnaires. The findings suggest that implementing software controls, evaluating missing data patterns, documenting the amount of time spent completing questionnaires, and effective manipulation check questions are essential to control potential bias in Web-based research involving college students.

    Full Text Available Websites have evolved into an excellent medium of information dissemination and visibility. Hence governments and organizations around the world have websites as primary medium for information communication. The information in government web sites, which are widely adopted in many countries, must be accessible for all people, easy to use, accurate and secure. Since the web is an important resource of information for millions of people at all levels, accessible websites can help people with disabilities too to participate and contribute more actively in society. In recent years, many people have devoted their efforts to the issue of quality of Web site. The Quality and reliability of the e-government website is a crucial factor for the successful implementation of the information society. In this study the effectiveness of various design parameters (HTML errors, load time and browser compatibility problems etc. on e-government website will be analysed by taking into considerations different website development standards recommended for them. The main objective of this study is to investigate the usability, accessibility and vulnerability of e-government web sites in Turkish Republic. Analysis was conducted using several automatic evaluation tools. The evaluation results show that the examined e-Government services have one or more accessibility issues. The results indicated that there is an urgent need to improve the design features of e-government website in order to be more effective and user-centric. The study also revealed security vulnerabilities in these web sites. Although the Turkish Ministry of Family and Social Policies as the framework for defining Web accessibility policy was launched at 2001, government web sites in the Turkish Republic have not been reviewed and still need great efforts to improve accessibility, usability and security. The author took 51 Government websites of Turkey, analyse their different parameters and on the

  17. State prescription drug price Web sites: how useful to consumers?

    Science.gov (United States)

    Tu, Ha T; Corey, Catherine G

    2008-02-01

    To aid consumers in comparing prescription drug costs, many states have launched Web sites to publish drug prices offered by local retail pharmacies. The current push to make retail pharmacy prices accessible to consumers is part of a much broader movement to increase price transparency throughout the health-care sector. Efforts to encourage price-based shopping for hospital and physician services have encountered widespread concerns, both on grounds that prices for complex services are difficult to measure and compare accurately and that quality varies substantially across providers. Experts agree, however, that prescription drugs are much easier to shop for than other, more complex health services. However, extensive gaps in available price information--the result of relying on Medicaid data--seriously hamper the effectiveness of state drug price-comparison Web sites, according to a new study by the Center for Studying Health System Change (HSC). An alternative approach--requiring pharmacies to submit price lists to the states--would improve the usefulness of price information, but pharmacies typically oppose such a mandate. Another limitation of most state Web sites is that price information is restricted to local pharmacies, when online pharmacies, both U.S. and foreign, often sell prescription drugs at substantially lower prices. To further enhance consumer shopping tools, states might consider expanding the types of information provided, including online pharmacy comparison tools, lists of deeply discounted generic drugs offered by discount retailers, and lists of local pharmacies offering price matches.

    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.

    When managing chronic illnesses, caregivers repeatedly seek online information about providing complex, long-term care but often neglect to find information about how to care for themselves. Poor health among caregivers is not only detrimental to their own well-being but may also result in harm to those for whom they care. For this reason, caregivers need access to information and activities about caring for themselves in addition to the information about managing home care they are already likely to seek. The HPN Family Caregivers Web site was developed to guide caregivers through the process of caring for themselves by establishing a caregiving routine, self-monitoring their mental and physical health, and practicing good sleep hygiene, while also managing the complexities of home care. While Web site information, activities, and algorithms for managing chronic illnesses need to be specific to each population, the content guiding caregivers to care for their own health is universal.

    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.

  10. Origins Of The Elements - An Educational Web Site

    Science.gov (United States)

    Samarasingha, Iranga; Ivans, I. I.

    2011-01-01

    This poster introduces a new and unique web site "ORIGINS OF THE ELEMENTS" to the astronomy and physics communities. The main objective of our site is to provide a useful reference guide to the origins of the elements for researchers, educators and students. Only a very few of the lightest elements have their origins at the earliest cosmological ages of the Universe, the Big Bang. Most of the elements found on the Earth, and in the rest of the Universe, owe their primary existence to stellar nucleosynthesis, either during the course of the energy generation lifetimes of stars, or in the exploding supernovae of stars at the end of their lives. A by-product of stellar energy generation and exploding supernovae is alchemy -- the ashes of the energy generation contribution of one element is another, more massive element. Although various reference sources are available to learn about nucleosynthesis, it's a challenging task to uncover appropriate study materials. In this single site, we present both data and recent research results in a concise and attractive structure. Using tables and charts, the material is presented in a multi-level style. For each of the elements in the periodic table, and for each of the stable isotopes in the chart of the nuclides, the site gives a clear visualization of their corresponding nucleosynthetic origins. As a consequence, the charts afford an insight into the patterns of nucleosynthesis. Moreover, the web site provides the student with an intuition to the relative distributions of those elements. Another important feature of our site is that users have direct access to the tabulated elemental abundances (both theoretical and observed) of stars and meteorites.

    2009-06-01

    Full Text Available The purpose of this study was to assess the pedagogical equivalence, as determined by knowledge gains, and the pedagogical effectiveness of certain components in a video-driven multimedia, web-based professional development training program as compared to a traditional, face-to-face program under real-world constraints of time and limited economic resources. The study focused on the use of video-driven multimedia, web-based instruction in the corporate environment to determine if the quality of the learning experience and the knowledge gained from the instruction were the same as with traditional methods. This experimental study assigned business professionals quasi-randomly to either a control group or an experimental group, where they attended either a live-instructed professional development program or a video-driven multimedia, web-based professional development program. Overall, results indicated that the video-driven multimedia, web-based instruction was not only pedagogically equivalent in terms of knowledge gains to the live instruction but that the knowledge gains were slightly higher among the web-based participants. Further, certain components in the web-based environment contributed more than components in the live environment to pedagogical effectiveness.

    2001-12-01

    Despite widespread use of lacustrine records to interpret paleolimnologic and paleoclimatic change, there is a large gap between the data published in peer-reviewed journals and those submitted for archive and available to other researchers online. A primary goal of the World Data Center (WDC) for paleoclimatology and the International Geosphere-Biosphere Programme (IGBP) - Past Global Changes (PAGES) core programme is to have full and open sharing of all data sets needed for global change studies. To help improve the quantity and quality of data submitted to the WDC for Paleoclimatology, we are developing online data submission and advanced interactive browse and access tools. Our poster presents a new web-site designed to make paleolimnology data more accessible by incorporating web-based data submission forms, a multi-proxy relational database, and interactive mapping tools. The WDC for Paleoclimatology is currently designing intuitive and streamlined web-based submission forms, which will allow investigators to quickly submit their data and metadata on-line. We are also importing all existing data and metadata in our archives into a multiproxy relational database that will allow users to quickly query and retrieve paleolimnological data, as well as display the data in various formats. Furthermore, we are implementing two Paleolimnology mapping tools that will allow users to search, display, and query data in a geographical format. The first tool, WebMapper, uses a Java applet to draw maps and display metadata. This will be supplemented by a plotting tool that will provide basic plotting functions to allow users to examine data before downloading them. The second mapping tool, ArcIMS, allows users to overlay paleoclimatic data with various GIS data sets in addition to providing basic spatial analysis functions. We believe that these new web-based features will encourage more extensive data sharing and submission, making paleolimnological data more available and

    Nursing students should exhibit competence in nursing skills in order to provide safe and quality patient care. This study describes the design and students' response to an interactive web-based course using streaming video technology tailored to students' needs and the course objectives of the fundamentals of nursing skills clinical course. A mixed-methodology design was used to describe the experience of 102 first-year undergraduate nursing students at a school of nursing in Jordan who were enrolled in the course. A virtual course with streaming videos was designed to demonstrate medication administration fundamental skills. The videos recorded the ideal lab demonstration of the skills, and real-world practice performed by registered nurses for patients in a hospital setting. After course completion, students completed a 30-item satisfaction questionnaire, 8 self-efficacy scales, and a 4-item scale solicited their preferences of using the virtual course as a substitute or a replacement of the lab demonstration. Students' grades in the skill examination of the procedures were measured. Relationships between the main variables and predictors of satisfaction and self-efficacy were examined. Students were satisfied with the virtual course (3.9 ± 0.56, out of a 5-point scale) with a high-perceived overall self-efficacy (4.38 ± 0.42, out of a 5-point scale). Data showed a significant correlation between student satisfaction, self-efficacy and achievement in the virtual course (r = 0.45-0.49, p streaming videos for clinical courses is a complex process that should be carefully designed to positively influence the learning experience. However, the learning benefits gained from such pedagogical approach are worth faculty, institution and students' efforts. Published by Elsevier Ireland Ltd.

    2000-08-01

    In the United States, Western Europe and other areas, groups opposing universal childhood immunization are reported to be gaining political momentum. A review was done of Internet sites opposing childhood immunization, with the goal of describing the philosophies and strategies used by the groups presenting them. A random sample of antivaccination Web sites was obtained using standard Internet search engines and the search terms "vaccination" and "immunization." These sites were analyzed for content, common themes, philosophy, affiliation with groups or organizations, and suggested strategies for avoiding vaccination. Twenty-six of the 51 sites found were randomly selected for review. Fifteen of these were associated with groups promoting the use of alternative medicine for preventing or treating infectious disease. Groups concerned with civil liberties were also represented, as were conspiracy theorists. Many groups have an interest in opposing universal childhood immunization, and some of them have a prominent presence on the Internet. Physicians and parents should be aware of the existence of these groups and their philosophies. Further research and educational efforts to counter their effects is necessary.

    2012-07-01

    Where on the Web can a middle school girl ask a female solar scientist about solar storms, the course and behavior of charged solar particles, and the origin of the Sun's dynamo—and also find out what the scientist was like as a child, whether the scientist has tattoos or enjoys snowboarding, what she likes and dislikes about her career, and how she balances her energy for work and family life? These kinds of exchanges happen at Solar Week (http://www.solarweek.org; see Figure 1). Established in 2000, Solar Week is an online resource for middle and lower high school students about the science of the Sun, sponsored by the Center for Science Education at the Space Sciences Laboratory (CSE@SSL) at the University of California, Berkeley (UC Berkeley). The Web site's goals are to educate students about the Sun and solar physics and to encourage future careers in science—especially for girls. One way is by giving solar scientists the chance to be relatable role models, to answer students' questions, and to share their experiences in an online forum.

The results of the research, based on the sample of medical libraries partaining to the Ljubljana medical circle, indicate that posibilities offered by databases accessible on internet are unutilizied. Medical libraries mostly use their web sites for presentation of their activities in a fairly rigid and unchanging format, including general information on the library, e-mail, mailing adresses, library regulations, but without much interactive information. The article indicates the necessity for improvement of the present state and offers a few advices on how to achieve the positive change.

    Based on a census of the 2015 Most Wired Hospitals, this content analysis aimed to find out how patient education has been integrated on these best IT hospitals' Web sites to serve the purposes of marketing and meeting online visitors' needs. This study will help hospitals to understand where the weaknesses are in their interactive patient education implementation and come up with a smart integration strategy. The study found that 70% of these hospitals had adopted interactive patient education contents, 76.6% of such contents were from a third-party developer, and only 20% of the hospitals linked their patient education contents to one or more of the hospital's resources while 26% cross-references such contents. The authors concluded that more hospitals should take advantage of modern information communication technology to cross-reference their patient education contents and to integrate such contents into their overall online marketing strategy to benefit patients and themselves.

    The purposes of this study were to develop a Social Cognitive Theory-based, structured Hip Fracture Prevention Web site for older adults and conduct a preliminary evaluation of its effectiveness. The Theory-based, structured Hip Fracture Prevention Web site is composed of learning modules and a moderated discussion board. A total of 245 older adults recruited from two Web sites and a newspaper advertisement were randomized into the Theory-based, structured Hip Fracture Prevention Web site and the conventional Web sites groups. Outcomes included (1) knowledge (hip fractures and osteoporosis), (2) self-efficacy and outcome expectations, and (3) calcium intake and exercise and were assessed at baseline, end of treatment (2 weeks), and follow-up (3 months). Both groups showed significant improvement in most outcomes. For calcium intake, only the Theory-based, structured Hip Fracture Prevention Web site group showed improvement. None of the group and time interactions were significant. The Theory-based, structured Hip Fracture Prevention Web site group, however, was more satisfied with the intervention. The discussion board usage was significantly correlated with outcome gains. Despite several limitations, the findings showed some preliminary effectiveness of Web-based health interventions for older adults and the use of a Theory-based, structured Hip Fracture Prevention Web site as a sustainable Web structure for online health behavior change interventions.

    Preparing images for publication has dealt with film and the photographic process. With picture archiving and communications systems, many departments will no longer produce film. This will change how images are produced for publication. DICOM, the file format for radiographic images, has to be converted and then prepared for traditional publication, 35-mm slides, the newest techniques of video projection, and the World Wide Web. Tagged image file format is the common format for traditional print publication, whereas joint photographic expert group is the current file format for the World Wide Web. Each medium has specific requirements that can be met with a common image-editing program such as Adobe Photoshop (Adobe Systems, San Jose, CA). High-resolution images are required for print, a process that requires interpolation. However, the Internet requires images with a small file size for rapid transmission. The resolution of each output differs and the image resolution must be optimized to match the output of the publishing medium.

    2014-01-01

    To update and extend prior work reviewing Web sites that discuss home drug testing for parents, and assess the quality of information that the Web sites provide, to assist them in deciding when and how to use home drug testing. We conducted a worldwide Web search that identified 8 Web sites providing information for parents on home drug testing. We assessed the information on the sites using a checklist developed with field experts in adolescent substance abuse and psychosocial interventions that focus on urine testing. None of the Web sites covered all the items on the 24-item checklist, and only 3 covered at least half of the items (12, 14, and 21 items, respectively). The remaining 5 Web sites covered less than half of the checklist items. The mean number of items covered by the Web sites was 11. Among the Web sites that we reviewed, few provided thorough information to parents regarding empirically supported strategies to effectively use drug testing to intervene on adolescent substance use. Furthermore, most Web sites did not provide thorough information regarding the risks and benefits to inform parents' decision to use home drug testing. Empirical evidence regarding efficacy, benefits, risks, and limitations of home drug testing is needed.

    2015-04-01

    To assess the accessibility and content of accredited hand surgery fellowship Web sites. A list of all accredited hand surgery fellowships was obtained from the online database of the American Society for Surgery of the Hand (ASSH). Fellowship program information on the ASSH Web site was recorded. All fellowship program Web sites were located via Google search. Fellowship program Web sites were analyzed for accessibility and content in 3 domains: program overview, application information/recruitment, and education. At the time of this study, there were 81 accredited hand surgery fellowships with 169 available positions. Thirty of 81 programs (37%) had a functional link on the ASSH online hand surgery fellowship directory; however, Google search identified 78 Web sites. Three programs did not have a Web site. Analysis of content revealed that most Web sites contained contact information, whereas information regarding the anticipated clinical, research, and educational experiences during fellowship was less often present. Furthermore, information regarding past and present fellows, salary, application process/requirements, call responsibilities, and case volume was frequently lacking. Overall, 52 of 81 programs (64%) had the minimal online information required for residents to independently complete the fellowship application process. Hand fellowship program Web sites could be accessed either via the ASSH online directory or Google search, except for 3 programs that did not have Web sites. Although most fellowship program Web sites contained contact information, other content such as application information/recruitment and education, was less frequently present. This study provides comparative data regarding the clinical and educational experiences outlined on hand fellowship program Web sites that are of relevance to residents, fellows, and academic hand surgeons. This study also draws attention to various ways in which the hand surgery fellowship application

    2013-01-01

    Little is known about veterans service organizations (VSOs) and their perspectives on veterans smoking or military tobacco control. Veterans have high smoking rates and many started smoking in the military, where a culture promoting use exists. A qualitative content analysis of VSO Web sites was conducted to classify health topics and identify tobacco-related information. Web sites were coded by trained raters from January to June of 2011. Data were entered, cleaned, and analyzed from July 2011 to January 2012. Twenty-four active VSO Web sites meeting inclusion criteria were rated independently. A comprehensive form was used to code 15 veteran-relevant health topics across multiple content areas/domains within the Web sites. Raters achieved 94.5% interrater agreement over nearly 5000 data points. Health content was coded as present or not within multiple VSO Web site areas/domains. The frequency of coverage by each VSO Web site and the number of VSO Web sites that mentioned a health topic in different Web site areas/domains were tabulated. A total of 277 health topics were addressed, with the top five being insurance/Tricare/Veterans Administration issues (28.2%), posttraumatic stress disorder (PTSD; 15.5%), disability/amputation/wounds (13.4%), Agent Orange (10.5%), and traumatic brain injury (9.0%). Tobacco was mentioned four times (1.4%) across all 24 VSO Web sites, and smoking cessation was never addressed. VSO Web sites provide little information on tobacco-related topics and none offered information about smoking cessation. Given the high rates of tobacco use among veterans and active-duty service members, and the interaction between smoking and PTSD symptoms and treatment outcomes, VSOs should consider making tobacco control and smoking cessation higher-priority health issues on their Web sites.

    2006-01-01

    We tested whether patients are more likely to pursue healthy behaviors (eg, physical activity, smoking cessation) if referred to a tailored Web site that provides valuable information for behavior change. In a 9-month pre-post comparison with nonrandomized control practices, 6 family practices (4 intervention, 2 control) encouraged adults with unhealthy behaviors to visit the Web site. For patients from intervention practices, the Web site offered tailored health advice, a library of national and local resources, and printouts for clinicians. For patients from control practices, the Web site offered static information pages. Patient surveys assessed stage of change and health behaviors at baseline and follow-up (at 1 and 4 months), Web site use, and satisfaction. During the 9 months, 932 patients (4% of adults attending the practice) visited the Web site, and 273 completed the questionnaires. More than 50% wanted physician assistance with health behaviors. Stage of change advanced and health behaviors improved in both intervention and control groups. Intervention patients reported greater net improvements at 1 month, although the differences approached significance only for physical activity and readiness to change dietary fat intake. Patients expressed satisfaction with the Web site but wished it provided more detailed information and greater interactivity with clinicians. Clinicians face growing pressure to offer patients good information on health promotion and other health care topics. Referring patients to a well-designed Web site that offers access to the world's best information is an appealing alternative to offering handouts or impromptu advice. Interactive Web sites can facilitate behavior change and can interface with electronic health records. Determining whether referral to an informative Web site improves health outcomes is a methodological challenge, but the larger question is whether information alone is sufficient to promote behavior change.

    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.

    2014-11-01

    To explore the role of Web-based platforms in behavioral health, the study examined usage of a Web site for supporting training and implementation of an evidence-based intervention. Using data from an online registration survey and Google Analytics, the investigators examined user characteristics and Web site utilization. Site engagement was substantial across user groups. Visit duration differed by registrants' characteristics. Less experienced clinicians spent more time on the Web site. The training section accounted for most page views across user groups. Individuals previously trained in the Cognitive-Behavioral Intervention for Trauma in Schools intervention viewed more implementation assistance and online community pages than did other user groups. Web-based platforms have the potential to support training and implementation of evidence-based interventions for clinicians of varying levels of experience and may facilitate more rapid dissemination. Web-based platforms may be promising for trauma-related interventions, because training and implementation support should be readily available after a traumatic event.

    Conesa-Fuentes, Maria C; Hernandez-Morante, Juan J

    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.

  19. Building a Playground: General Guidelines for Creating Educational Web Sites for Children.

    2010-11-01

    Since 2004, the number of children online has increased 18%, compared with a 10% increase in total users. Not only do children represent a growing segment of Internet users, much of what they do online has a specific purpose: education. To help technical communicators create educational Web sites for children, we offer a set of guidelines to direct the design process. Nine children participated in a usability test of the CARES Playground, an educational Web site geared toward 7- to 9-year-olds. The site was designed by a group of graduate students in professional writing based on a review of the (admittedly limited) literature dealing with designing Web sites for children. This paper matches common themes from existing literature to the results of the usability tests. Since all the information on designing Web sites for children emerged from the literature of designing Web sites for adults, the themes of navigation, appearance, and content are not unfamiliar. However, the interpretation of those common issues for children-as well as the children's reaction to them-may be surprising. Technical communicators need to be conscious and deliberate when designing Web sites for children. To ensure that educational Web sites are able to meet their learning goals, careful consideration of children's developmental abilities and Web preferences must be considered. We present several guidelines as a starting point, though further research is needed to confirm and expand upon them.

    National leaders are calling for opportunities to facilitate the Future of Nursing. Opportunities can be encouraged through state nurses association Web sites, which are part of the American Nurses Association, that are well designed, with appropriate content, and in a language professional nurses understand. The American Nurses Association and constituent state nurses associations provide information about nursing practice, ethics, credentialing, and health on Web sites. We conducted usability evaluations to determine compliance with heuristic and ethical principles for Web site design. We purposefully sampled 27 nursing association Web sites and used 68 heuristic and ethical criteria to perform systematic usability assessments of nurse association Web sites. Web site analysis included seven double experts who were all RNs trained in usability analysis. The extent to which heuristic and ethical criteria were met ranged widely from one state that met 0% of the criteria for "help and documentation" to states that met greater than 92% of criteria for "visibility of system status" and "aesthetic and minimalist design." Suggested improvements are simple yet make an impact on a first-time visitor's impression of the Web site. For example, adding internal navigation and tracking features and providing more details about the application process through help and frequently asked question documentation would facilitate better use. Improved usability will improve effectiveness, efficiency, and consumer satisfaction with these Web sites.

    2012-07-01

    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.

    Four of five families are affected by stroke. Many caregivers access the Internet and gather healthcare information from Web-based sources. The purpose of this descriptive evaluation was to assess the usage and design of the Caring∼Web site, which provides education/support for family caregivers of persons with stroke residing in home settings. Thirty-six caregivers from two Midwest states accessed this intervention in a 1-year study. The average participant was 54 years old, White, woman, and the spouse of the care recipient. In a telephone interview, four Web site questions were asked twice a month/bimonthly, and a 33-item survey at the conclusion of the study evaluated the Web site usage and design of its components. Descriptive analysis methods were used, and statistics were collected on the number of visits to the Web site. On average, participants logged on to the Web site 1-2 hours per week, although usage declined after several months for some participants. Participants positively rated the Web site's appearance and usability that included finding the training to be adequate. Web site designers can replicate this intervention for other health conditions.

    2008-10-01

    Appropriateness and adequacy of health information on the Internet varies. Given there is no validated instrument for web site evaluation focusing on elective general surgical procedures, our goal was to create a composite score as a web site quality rating system. The components of a composite score were developed through a literature review and included Agency for Healthcare Research and Quality guidelines of "Having Surgery? What You Need to Know" and previously published health-related web site scales. All criteria are given equal weight (0/1 scale). The composite score is reported as a percentage of a total possible 16 points. To pilot the rating scale, a web search for roux-en-y gastric bypass (RYGB) was used. Validation compared the composite score with an evaluation by surgeons. Mean composite score for 18 RYGB web sites was 48 per cent (range, 19% to 75%). Composite score validation used a cutoff value of 50 per cent. There was 100 per cent agreement (kappa = 1.0) between composite and surgeon scores. This is the first validated comprehensive composite score to evaluate the web site quality for patients undergoing elective surgery. This score shows promise in increasing efficiency of surgical practices by providing a way in which we can evaluate web sites and encourage our patients to become well informed by reading only high-quality web sites.

    The Internet contains a large amount of useful information on many subjects, but also information of doubtful quality. To help identify Web sites on vaccine safety that fulfil good practice, the Global Advisory Committee on Vaccine Safety of the World Health Organization (WHO) has published criteria to which sites should adhere and a listing of Web sites that fulfil them. There are no studies describing the common attributes of these sites. To examine the attributes, design characteristics and resources of Web sites belonging to the Vaccine Safety Net (VSN) of the WHO. A cross-sectional, descriptive observational study using an evaluation questionnaire was carried out applied to the VSN web sites listed in March-April 2007. Twenty-six Web sites accredited by the VSN by April 2007 were analysed. With respect to design and quality, all sites contained information about the site manager. Postal and Email addresses were available for 84.6% of the sites. About privacy and personal data processing, 73.1% of sites specified the data protection procedure used and stated that data were not sold or passed third parties. The most-used language was English (76.9%). 96.3% of sites had links to other pro-vaccination sites and 19.2% provided the addresses of vaccination centres. 63.6% of webs were aimed at general public and health care workers but there was no clear separation of documents or different entry routes. With respect to information on vaccine safety, 84.6% of sites had information on adverse effects. In the general information section, 92.3% of sites had a new developments section. Some sites had multiple sources of financing and in 57% of sites, the financing was public. The most-important plus factors found were the transparency of financing, the lack of links to the pharmaceutical industry, the transparency of site management and responsibility and the proven scientific quality and constant updating of contents.

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

    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.

    2016-07-01

    To evaluate the validity of fertility web sites and applications (apps) by comparing the predicted fertile window of these modalities to the actual fertile window of a standard 28-day cycle. This was a descriptive study. The top resulting free web sites and electronic apps downloadable to a cellular phone that provide calendars for fertility and ovulation prediction were assessed. Cycles were standardized to 28 days in length, 4 days of menses, and the last menstrual period was set to January 1, 2015. The predicted date of ovulation and fertility window generated were compared with an actual estimated date of ovulation on cycle day 15, January 15, and a fertile window consisting of cycle day 10 to cycle day 15, the day of ovulation plus the preceding 5 cycle days, January 10-15. Data from 20 web sites and 33 apps were collected. Of all the web sites and apps used, one web site and three apps predicted the precise fertile window. Web sites and electronic apps used by the general public to predict fertile windows are generally inaccurate, although the clinical effect of this inaccuracy is unknown. Although they all include the most fertile cycle day, the range of the fertility window varies widely. Patients who are trying to conceive with the assistance of calendars generated from web sites and electronic apps should be counseled on the inaccuracy of these modalities.

    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.

    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.

    Schabler, T. G.; Byrne, J. M.

    2013-12-01

    One of the common sources of information for public and classroom climate change education is YouTube. There is no way of knowing how well the information is being received and interpreted by users; and there is little knowledge as to how individuals and groups respond to science videos from reputable sources, or to denial videos that counter the science consensus. This two-part study is intended to (i) evaluate the science communication efficacy of the most viewed ';climate change' Youtube videos; and (ii) determine how selected high-view count videos on climate change influence university student opinions. Ninety-nine pro-climate change and climate denier videos were evaluated and subjectively scored by a senior university student familiar with the basics of climate science. All these videos come forward on YouTube under the search keywords 'climate change.' The videos were ranked by numbers of views, and under a range of subjective variables. A randomized selection of short videos with overall high rankings was shared with student populations, and before and after perspectives was recorded through a short group survey. We hope the results inform the science education community on perceptions of education videos, with an eventual goal of informing better video production to communicate climate change for public and classroom education.

    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.].

    Social networking Web sites such as Facebook have grown rapidly in popularity. It is unknown how such sites affect the ways in which medical trainees investigate and interact with graduate medical education (GME) programs. To evaluate the use of social networking Web sites as a means for osteopathic medical students, interns, residents, and fellows to interact with GME programs and report the degree to which that interaction impacts a medical trainee's choice of GME program. An anonymous, 10-item electronic survey on social networking Web sites was e-mailed to osteopathic medical student, intern, resident, and fellow members of the American College of Osteopathic Family Physicians. The weighted least squares test and the Fisher exact test were used for data analysis. A total of 9606 surveys were distributed, and 992 (10%) were completed. Nine hundred twenty-eight (93%) of the respondents used social networking Web sites, with the most popular services being Facebook (891 [90%]; P=.03), the Student Doctor Network (278 [28%]), and LinkedIn (89 [9%]; P=.03). Three hundred fifty-three respondents (36%; P=.52) were connected with a professional organization and 673 (68%; P=.73) used social networking Web sites for job searching related to GME programs or postresidency employment. Within the population of 497 third-, fourth-, and fifth-year osteopathic medical students, 136 (27%) reported gleaning information about programs through social networking Web sites (P=.01). Within the total population, 100 of 992 (10%) reported that this information influenced their decisions (P=.07). Of note, 144 (14%) of the total 992 respondents reported that the programs they applied to did not have any presence on social networking Web sites (P=.05). Our results indicate that social networking Web sites have a present and growing influence on how osteopathic medical students, interns, residents, and fellows learn about and select a GME program.

    Full Text Available We examine how accurately the belief system or cultural concepts of Maori, the indigenous people of New Zealand, is reconstructed in the virtual world of the Internet. 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.

  20. Soil food web changes during spontaneous succession at post mining sites: a possible ecosystem engineering effect on food web organization?

    Directory of Open Access Journals (Sweden)

    Jan Frouz

    Full Text Available Parameters characterizing the structure of the decomposer food web, biomass of the soil microflora (bacteria and fungi and soil micro-, meso- and macrofauna were studied at 14 non-reclaimed 1- 41-year-old post-mining sites near the town of Sokolov (Czech Republic. These observations on the decomposer food webs were compared with knowledge of vegetation and soil microstructure development from previous studies. The amount of carbon entering the food web increased with succession age in a similar way as the total amount of C in food web biomass and the number of functional groups in the food web. Connectance did not show any significant changes with succession age, however. In early stages of the succession, the bacterial channel dominated the food web. Later on, in shrub-dominated stands, the fungal channel took over. Even later, in the forest stage, the bacterial channel prevailed again. The best predictor of fungal bacterial ratio is thickness of fermentation layer. We argue that these changes correspond with changes in topsoil microstructure driven by a combination of plant organic matter input and engineering effects of earthworms. In early stages, soil is alkaline, and a discontinuous litter layer on the soil surface promotes bacterial biomass growth, so the bacterial food web channel can dominate. Litter accumulation on the soil surface supports the development of the fungal channel. In older stages, earthworms arrive, mix litter into the mineral soil and form an organo-mineral topsoil, which is beneficial for bacteria and enhances the bacterial food web channel.

    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.

    The Space Place is a successful NASA web site that benefits upper elementary school students and educators by providing games, activities, and resources to stimulate interest in science, technology, engineering, and mathematics, as well as to inform the audience of NASA’s contributions. As online social networking grows to be a central component of modern communication, The Space Place has explored the benefits of integrating social networks with the web site to increase awareness of materials the web site offers. This study analyzes the capabilities of social networks, and specifically the demographics of Twitter and Facebook. It then compares these results with the content, audience, and perceived demographics of The Space Place web site. Based upon the demographic results, we identified a target constituency that would benefit from the integration of social networks into The Space Place web site. As a result of this study, a Twitter feed has been established that releases a daily tweet from The Space Place. In addition, a Facebook page has been created to showcase new content and prompt interaction among fans of The Space Place. Currently, plans are under way to populate the Space Place Facebook page. Each social network has been utilized in an effort to spark excitement about the content on The Space Place, as well as to attract followers to the main NASA Space Place web site. To pursue this idea further, a plan has been developed to promote NASA Space Place’s social media tools among the target audience.

    1997-06-01

    The delivery of educational materials is undergoing a remarkable change from the traditional lecture method to dissemination of courses via the World Wide Web. This paradigm shift from a paper-based structure to an electronic one has profound implications for university faculty. Students are enrolling in classes with the expectation of using technology and logging on to the Internet, and professors are realizing that the potential of the Web can have a significant impact on classroom activities. An effective method of integrating electronic technologies into teaching and learning is to publish classroom materials on the World Wide Web. Already, many faculty members are creating their own home pages and Web sites for courses that include syllabi, handouts, and student work. Additionally, educators are finding value in adding hypertext links to a wide variety of related Web resources from online research and electronic journals to government and commercial sites. A number of issues must be considered when developing course-based Web sites. These include meeting the needs of a target audience, designing effective instructional materials, and integrating graphics and other multimedia components. There are also numerous technical issues that must be addressed in developing, uploading and maintaining HTML documents. This article presents a model for a university faculty who want to begin using the Web in their teaching and is based on the experiences of two College of Education professors who are using the Web as an integral part of their graduate courses.

    Video-sharing sites have become increasingly important in recent years in providing information and orienting people's decisions relating to their health. Adolescents and their families use internet to obtain information on pediatric oncological diseases. We describe the availability and type of video content and origin on YouTube relating to a particular set of pediatric neoplastic diseases, that is, rhabdomyosarcoma and soft-tissue sarcoma. A total of 149 videos were analyzed: 25 were considered as useful; only 1 video was produced by a doctor, whereas 82.5% were produced by patients or their families, in many cases for commemorating the death of a child. Our observations indicate that video-sharing sites have become tools, such as blogs and social media, that make it easier for patients to describe their impressions and experiences of the disease, and this could help other patients devise strategies for coping with the disease, providing them with support and opportunities for sharing information and resources.

  10. Interactive web site and app for early magnetic resonance education

    DEFF Research Database (Denmark)

    Hanson, Lars G.

    2016-01-01

    Teaching and understanding basic Magnetic Resonance (MR) is a challenge. This is clear from the educational literature that often repeats misinterpretations of quantum mechanics reminiscent of its earliest formulations (see www.drcmr.dk/MR that also links to the developed software). Modern quantum...... formulations of MR are much closer to classical descriptions than to typical quantum inspired myths frequent in literature. This opens for intuitive educational computer simulation using modern web technologies offering excellent interactive possibilities for experimentation....

    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 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.

    Walther, Joseph B; Wang, Zuoming; Loh, Tracy

    2004-09-03

    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. 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. 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. 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. 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.

  20. 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

  1. Quality, Range, and Legibility in Web Sites Related to Orofacial Functions

    2013-09-01

    Full Text Available Introduction: Plenty of information about health is available on the Internet; however, quality and legibility are not always evaluated. Knowledge regarding orofacial functions can be considered important for the population because it allows proper stimulus, early diagnosis, and prevention of the oral myofunctional alterations during early infancy. Objective: The aim was evaluate the quality, legibility, and range of Web sites available in Brazilian Portuguese regarding the orofacial functions. Methods: Selected Web sites with information directed to parents/caregivers of babies regarding breast-feeding, feeding after 6 months, deleterious oral habits, and breathing and speech were studied. The Web sites were evaluated through the application of Flesch Reading Ease Test and aspects of the Health on the Net (HON modified code (HONCode; the range of the subjects addressed was compared with other aspects of infant development. Results: From the access of 350 pages of the Internet, 35 Web sites were selected and 315 excluded because they did not meet the inclusion criteria. In relation to legibility, Web sites scored an average of 61.23% in the Flesch Test, and the application of the modified HONCode showed an average of 6.43 points; an average of 2.49 subjects were found per Web site evaluated, with information on breast-feeding being more frequent and subjects such as breathing and speech less frequent. Conclusions: Web sites that deal with orofacial functions presented standard legibility classification. Only half of the ethical principles were considered by the modified HONCode in their majority, and most addressed subjects after “breast-feeding” were presented with restricted range.

    This study content analyzed a randomly selected stratified national sample of 203 four-year United States colleges' counseling center Web sites to assess the degree to which such sites feature information and reference services for lesbian, gay, bisexual, and transgender (LGBT) collegians. Results revealed that LGBT-targeted communications were infrequent. For instance, fewer than one third of counseling center Web sites described individual counseling opportunities for LGBT students, fewer than 11% mentioned group counseling opportunities, and fewer than 6% offered a university crafted pamphlet with information about LGBT issues and resources. Findings are interpreted within the context of prior LGBT student health research.

    Sandia National Laboratories proposed using airborne synthetic aperture RADAR (SAR) collected in VideoSAR mode to characterize the Underground Nuclear Explosion Signature Experiment (UNESE) test bed site at the Nevada National Security Site (NNSS). The SNL SAR collected airborne, Ku-band (16.8 GHz center frequency), 0.2032 meter ground resolution over NNSS in August 2014 and X-band (9.6 GHz), 0.1016 meter ground resolution fully-polarimetric SAR in April 2015. This paper reports the findings of processing and exploiting VideoSAR for creating digital elevation maps, detecting cultural artifacts and exploiting full-circle polarimetric signatures. VideoSAR collects a continuous circle of phase history data, therefore, imagery can be formed over the 360-degrees of the site. Since the Ku-band VideoSAR had two antennas suitable for interferometric digital elevation mapping (DEM), DEMs could be generated over numerous aspect angles, filling in holes created by targets with height by imaging from all sides. Also, since the X-band VideoSAR was fully-polarimetric, scattering signatures could be gleaned from all angles also. Both of these collections can be used to find man-made objects and changes in elevation that might indicate testing activities. VideoSAR provides a unique, coherent measure of ground objects allowing one to create accurate DEMS, locate man-made objects, and identify scattering signatures via polarimetric exploitation. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.

    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.

    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.

    2004-01-01

    In the last years the rapid development of the Internet and new communication technologies has had a great impact on psychology and psychotherapy. Psychotherapists seem to rely with more and more interest on the new technological tools such as videophone, audio and video chat, e-mail, SMS and the new Instant Messaging Tools (IMs). All these technologies outline a stimulating as well as complex scenario: in order to effectively exploit their potential, it is important to study which is the possible role played by the Internet-based tools inside a psychotherapeutic iter. Could the technology substitute the health care practitioners or are these tools only a resource in addition to the traditional ones in the therapist's hand? The major aim of this chapter is to provide a framework for the integration of old and new tools in mental health care. Different theoretical positions about the possible role played by e-therapy are reported showing the possible changes that psychotherapy will necessarily face in a cyber setting. The VEPSY website, an integration of different Internet-based tools developed within the VEPSY UPDATED Project, is described as an example of clinical application matching between old (and functional) practices with new (and promising) media for the treatment of different mental disorders. A rationale about the possible scenarios for the use of the VEPSY website in the clinical process is provided.

    Many smokers are unable to access effective behavioral smoking cessation therapies due to location, financial limitations, schedule, transportation issues or other reasons. We report results from a prospective observational study in which a promising novel behavioral intervention, Mindfulness Training for Smokers was provided via web-based video instruction with telephone-based counseling support. Data were collected on 26 low socioeconomic status smokers. Participants were asked to watch eight video-based classes describing mindfulness skills and how to use these skills to overcome various core challenges in tobacco dependence. Participants received eight weekly phone calls from a smoking cessation coach who provided general support and answered questions about the videos. On the quit day, participants received two weeks of nicotine patches. Participants were a mean of 40.5 years of age, smoked 16.31 cigarettes per day for 21.88 years, with a mean of 6.81 prior failed quit attempts. Participants completed a mean of 5.55 of 8 online video classes with a mean of 23.33 minutes per login, completed a mean of 3.19 of 8 phone coach calls, and reported a mean meditation practice time of 12.17 minutes per day. Smoking abstinence was defined as self-reported abstinence on a smoking calendar with biochemical confirmation via carbon monoxide breath-test under 7 parts per million. Intent-to-treat analysis demonstrated 7-day point prevalence smoking abstinence at 4 and 6-months post-quit of 23.1% and 15.4% respectively. Participants showed a significant pre- to post-intervention increase in mindfulness as measured by the Five-Factor Mindfulness Questionnaire, and a significant pre- to post-intervention decrease in the Anxiety Sub-scale of the Depression Anxiety and Stress Scale. Results suggest that Mindfulness Training for Smokers can be provided via web-based video instruction with phone support and yield reasonable participant engagement on intervention practices and that

    O'Grady Laura A

    2006-02-01

    Full Text Available Abstract Background Members of the HIV/AIDS community are known to use web-based tools to support learning about treatment issues. Initial research indicated components such as message forums or web-based documentation were effectively used by persons with HIV/AIDS. Video has also shown promise as a technology to aid consumer health education. However, no research has been published thus far investigating the impact of web-based environments combining these components in an educational workshop format. Methods In this qualitative study HIV/AIDS community members provided feedback on an integrated web-based consumer health education environment. Participants were recruited through organizations that serve the HIV/AIDS community located in Toronto, Canada. Demographics, data on Internet use, including messages exchanged in the study environment were collected. A group interview provided feedback on usability of the study environment, preferences for information formats, use of the message forum, and other sources for learning about treatment information. Results In this pilot study analysis of the posted messages did not demonstrate use for learning of the workshop content. Participants did not generally find the environment of value for learning about treatment information. However, participants did share how they were meeting these needs. It was indicated that a combination of resources are being used to find and discuss treatment information, including in-person sources. Conclusion More research on the ways in which treatment information needs are being met by HIV/AIDS community members and how technology fits in this process is necessary before investing large amounts of money into web-based interventions. Although this study had a limited number of participants, the findings were unexpected and, therefore, of interest to those who intend to implement online consumer health education initiatives or interventions.

    2014-01-01

    To help people shop for lower cost providers, several states have created their own price transparency Web sites or passed legislation mandating health plans provide such information. New Hampshire's HealthCost Web site is on the forefront of such initiatives. Despite the growing interest in price transparency, little is known about such efforts, including how often these tools are used and for what reason. We examined the use of New Hampshire HealthCost over a 3-year period. Approximately 1% of the state's residents used the Web site, and the most common searches were for outpatient visits, magnetic resonance imaging (MRI) or computed tomography (CT) scans, and emergency department visits. The results provide a cautionary note on the level of potential interest among consumers in this information but may guide others on practically what are the most "shop-able" services for patients. © The Author(s) 2014.

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.

    Despite concerns about online health information and efforts to improve its credibility, how users evaluate and utilize such information presented in Web sites and online discussion groups may involve different evaluative mechanisms. This study examined credibility and homophily as two underlying mechanisms for social influence with regard to online health information. An original experiment detected that homophily grounded credibility perceptions and drove the persuasive process in both Web sites and online discussion groups. The more homophilous an online health information stimulus was perceived as being, the more likely people were to adopt the advice offered in that particular piece of information.

    Discovery of potentially deleterious sequence variants is important and has wide implications for research and generation of new hypotheses in human and veterinary medicine, and drug discovery. The GenProBiS web server maps sequence variants to protein structures from the Protein Data Bank (PDB), and further to protein-protein, protein-nucleic acid, protein-compound, and protein-metal ion binding sites. The concept of a protein-compound binding site is understood in the broadest sense, which includes glycosylation and other post-translational modification sites. Binding sites were defined by local structural comparisons of whole protein structures using the Protein Binding Sites (ProBiS) algorithm and transposition of ligands from the similar binding sites found to the query protein using the ProBiS-ligands approach with new improvements introduced in GenProBiS. Binding site surfaces were generated as three-dimensional grids encompassing the space occupied by predicted ligands. The server allows intuitive visual exploration of comprehensively mapped variants, such as human somatic mis-sense mutations related to cancer and non-synonymous single nucleotide polymorphisms from 21 species, within the predicted binding sites regions for about 80 000 PDB protein structures using fast WebGL graphics. The GenProBiS web server is open and free to all users at http://genprobis.insilab.org. © The Author(s) 2017. Published by Oxford University Press on behalf of Nucleic Acids Research.

    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.

    2017-06-01

    Research has demonstrated that breast milk significantly decreases morbidities that impact length of stay for preterm infants, but there is a need to test interventions to improve breastfeeding outcomes. Since many Americans are using technologies such as the Intranet and smartphones to find health information and manage health, a Web site was developed for mothers who provide breast milk for their preterm hospitalized infants. This study examined the efficacy of a Web site for mothers to educate them about breast milk expression and assist them in monitoring their breast milk supply. Quantitative and qualitative data were collected from mothers whose preterm infants were hospitalized in a level IV neonatal intensive care unit (NICU) or transitional care unit (TCU) in an urban academic medical center in the Midwest. Eighteen mothers participated in evaluation of the Web site. Thirteen mothers consistently logged on to the password-protected Web site (mean [standard deviation] = 13.3 [11.7]) times. Most participants, (69.2%), reported they used the breast milk educational information. Most mothers indicated that using the Web site log helped in tracking their pumping. These findings can be used to direct the design and development of web-based resources for mothers of preterm infants IMPLICATIONS FOR PRACTICE:: NICU and TCU staffs need to examine and establish approaches to actively involve mothers in monitoring the establishment and maintenance of an adequate supply of breast milk to improve neonatal health outcomes. An electronic health application that incorporates the features identified in this study should be developed and tested.

    People who use the Internet to research health topics do not usually find all the information they need and do not trust what they read. This study was designed to assess the reliability, accessibility, readability, and popularity of cancer Web sites in Spanish and to analyze the suitability of Web site content in accordance with the specific information needs of cancer patients. This was a two-phase, cross-sectional, descriptive study. The first phase involved data gathering through online searches and direct observation. The second phase involved individual structured interviews with 169 patients with breast, prostate, bladder, and kidney cancer. Spearman rank correlations were calculated between variables. Most sites belonged to nonprofit organizations, followed by universities or medical centers (14%). Thirty-one percent of the Web sites had quality seals, 59% provided details of authorship, 62% provided references to bibliographic sources, 38% identified their funding sources, and 54% showed the date of their last update. Twenty-one percent of the Web sites did not meet the minimum accessibility criteria. With regard to readability, 24% of the texts were considered to be "quite difficult." Patients' information needs vary depending on the type of cancer they have, although all patients want to know about the likelihood of a cure, survival rates, the side effects, and risks of treatment. The health information on cancer available on the Internet in Spanish is not very reliable, accessible, or readable and is not necessarily the information that breast, kidney, prostate, and bladder cancer patients require. The content of cancer Web sites needs to be assessed according to the information needs of patients.

    To evaluate limited English proficiency (LEP) Latino caregiver asthma knowledge after exposure to an educational video designed for this target group. A cross-sectional, interventional study was performed. We aimed to evaluate the post-test impact on asthma knowledge from baseline after exposure to a patient-centered, evidence-based, and professionally produced Spanish asthma educational video. Participants included LEP Latino caregivers of children 2-12 years old with persistent asthma. Enrollment was performed during ED encounters or scheduled through a local community organization. Asthma knowledge was measured with a validated Spanish parental asthma knowledge questionnaire. Differences in mean scores were calculated with a paired t-test. Twenty caregivers were enrolled. Participants included mothers (100%) from Puerto Rico (75%), with a high-school diploma or higher (85%), with no written asthma action plan (65%), whose child's asthma diagnosis was present for at least 3 years (80%). Mean baseline asthma knowledge scores improved 8 points from 58.4 to 66.4 after watching the educational video (95% CI 5.3-10.7; t(19) = 6.21, p asthma knowledge for a Latino population facing communication barriers to quality asthma care.

    2016-12-14

    Men who have sex with men (MSM), particularly MSM who identify as African-American or Black (BMSM), are the sociodemographic group that is most heavily burdened by the human immunodeficiency virus (HIV) epidemic in the United States. To meet national HIV testing goals, there must be a greater emphasis on novel ways to promote and deliver HIV testing to MSM. Obstacles to standard, clinic-based HIV testing include concerns about stigmatization or recognition at in-person testing sites, as well as the inability to access a testing site due to logistical barriers. This study examined the feasibility of self-administered, at-home HIV testing with Web-based peer counseling to MSM by using an interactive video chatting method. The aims of this study were to (1) determine whether individuals would participate in at-home HIV testing with video chat-based test counseling with a peer counselor, (2) address logistical barriers to HIV testing that individuals who report risk for HIV transmission may experience, and (3) reduce anticipated HIV stigma, a primary psychosocial barrier to HIV testing. In response to the gap in HIV testing, a pilot study was developed and implemented via mailed, at-home HIV test kits, accompanied by HIV counseling with a peer counselor via video chat. A total of 20 MSM were enrolled in this test of concept study, 80% of whom identified as BMSM. All participants reported that at-home HIV testing with a peer counseling via video chat was a satisfying experience. The majority of participants (13/18, 72%) said they would prefer for their next HIV testing and counseling experience to be at home with Web-based video chat peer counseling, as opposed to testing in an office or clinic setting. Participants were less likely to report logistical and emotional barriers to HIV testing at the 6-week and 3-month follow-ups. The results of this study suggest that self-administered HIV testing with Web-based peer counseling is feasible and that MSM find it to be a

    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.

    Health Literacy Online: A Guide to Writing and Designing Easy-to-Use Health Web Sites is a practical and well-written resource for public health and health communication professionals and web designers. This guide builds on the principles of web usability and adds to existing best practices by providing research-based strategies for writing and designing health websites especially for users with limited literacy and health literacy skills. This guide synthesizes years of lessons learned from Office of Disease Prevention and Health Promotion's original research with hundreds of web users, experience with revising the healthfinder.gov, as well as strategies supported by the Research-Based Web Design and Usability Guidelines (Usability.gov). In the United States, roughly one third of adults have limited literacy skills, yet far more (as many as 90%) have limited health literacy skills, meaning they have trouble understanding complex health information. This how-to guide is timely and developed with the aim of creating easy-to-use health websites to reach as many web users as possible, especially those with limited literacy and health literacy skills.

    2013-07-01

    The importance and complexity of clinical trials is continuously increasing, especially in innovative specialties like ophthalmology. Therefore an efficient clinical trial site organisational structure is essential. In modern internet times, this can be accomplished by web-based applications. In total, 3 software applications (Vibe on Prem, Sharepoint and open source software) were evaluated in a clinical trial site in ophthalmology. Assessment criteria were set; they were: reliability, easiness of administration, usability, scheduling, task list, knowledge management, operating costs and worldwide availability. Vibe on Prem customised by the local university met the assessment criteria best. Other applications were not as strong. By introducing a web-based application for administrating and organising an ophthalmological trial site, studies can be conducted in a more efficient and reliable manner.

As the number of web sites increased over the years, the size of information also grew considerably. Search engines facilitating access to information utilize metadata for cataloging purposes. Metadata is data about data. The structure of web sites and their diversity require the cataloging of web sites. Despite this, no efforts have been made to catalog Turkish web sites created in our country. However, it is obvious that saving, organising, sharing information and converting it into new information by way of feedback will accelerate and increase productivity. İlk web sitesinin Ağustos 1991'de çevrim içi olmasından bu yana, internette yayın yapan web sitesi sayısı 200 milyonu aşmıştır. Ülkemizde Mayıs 2009 itibarıyla 191.631 web sitesi bulunmaktadır.

The first section that assesses reliability of the Web site was 4.38 over 5; mean score of the second section that measures the quality of the provided information on treatment/care options was 4.30, and mean score of the third section that gives a general evaluation of the material was 4.1. The Web site content achieved an average score of 3.47 over 4 after evaluation by experts. The Web site system usability score was found to be 79.4 over 100. The Web site was utilized mostly for exercises in bed (76.3%; n = 29), use of medications, and patient safety (68.4%; n = 26). It was determined that those who were younger and employed and had no previous experience of nursing any patient utilized relatively more from the section of patient nutrition and oral care and married family caregivers from the body hygiene section. The Web site quality and content were judged to be good and reliable to use. The Web site was efficiently used by caregivers.

    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 .

    Foodborne illness is a serious and preventable public health problem, with high health and economic tolls in the United States. Local governments play an important role in food safety, with local health departments (LHDs) responsible for licensing and inspecting restaurants. Foodborne illness complaints from the public result in identification of more serious and critical food safety violations than regularly scheduled inspections; however, few people report foodborne illness. Availability of existing methods for the public to report foodborne illness to LHDs across the United States was examined. In 2016, data were collected and analyzed from a nationally representative stratified sample of 816 LHDs. Each LHD Web site was examined to determine whether the Web site included a way for constituents to report a suspected foodborne illness. Just 27.6% of LHD Web sites included a way for constituents to report a suspected foodborne illness. LHDs with reporting mechanisms were serving significantly larger populations and had significantly more staff members, higher revenues, and higher expenditures. Health departments with reporting mechanisms were also significantly more likely to conduct environmental health surveillance activities, to regulate, inspect, and/or license food service establishments, and to be involved in food safety policy. Consumer reports of suspected foodborne illness help identify serious and critical food safety violations in food establishments; however, foodborne illness is vastly underreported by the US public. While more evidence is needed on how current systems are working, increasing the visibility and availability of Web-based reporting mechanisms through the following strategies is recommended: (1) test and modify search functions on LHD Web sites to ensure consumers find reporting mechanisms; (2) add a downloadable form as an option for reporting; (3) coordinate with state health departments to ensure clear instructions are available for

    2010-01-01

    Full Text Available Sensor networks have been a very active area of research in recent years. However, most of the sensors used in the development of these networks have been local and nonimaging sensors such as acoustics, seismic, vibration, temperature, humidity. The emerging development of video sensor networks poses its own set of unique challenges, including high-bandwidth and low latency requirements for real-time processing and control. This paper presents a systematic approach by detailing the design, implementation, and evaluation of a large-scale wireless camera network, suitable for a variety of practical real-time applications. We take into consideration issues related to hardware, software, control, architecture, network connectivity, performance evaluation, and data-processing strategies for the network. We also perform multiobjective optimization on settings such as video resolution and compression quality to provide insight into the performance trade-offs when configuring such a network and present lessons learned in the building and daily usage of the network.

    Web-based surveys are increasingly used to capture data essential for human immunodeficiency virus (HIV) prevention research. However, there are challenges in ensuring the informed consent of Web-based research participants. The aim of our study was to develop and assess the efficacy of alternative methods of administering informed consent in Web-based HIV research with men who have sex with men (MSM). From July to September 2014, paid advertisements on Facebook were used to recruit adult MSM living in the United States for a Web-based survey about risk and preventive behaviors. Participants were randomized to one of the 4 methods of delivering informed consent: a professionally produced video, a study staff-produced video, a frequently asked questions (FAQs) text page, and a standard informed consent text page. Following the behavior survey, participants answered 15 questions about comprehension of consent information. Correct responses to each question were given a score of 1, for a total possible scale score of 15. General linear regression and post-hoc Tukey comparisons were used to assess difference (P<.001) in mean consent comprehension scores. A mediation analysis was used to examine the relationship between time spent on consent page and consent comprehension. Of the 665 MSM participants who completed the comprehension questions, 24.2% (161/665) received the standard consent, 27.1% (180/665) received the FAQ consent, 26.8% (178/665) received the professional consent video, and 22.0% (146/665) received the staff video. The overall average consent comprehension score was 6.28 (SD=2.89). The average consent comprehension score differed significantly across consent type (P<.001), age (P=.04), race or ethnicity (P<.001), and highest level of education (P=.001). Compared with those who received the standard consent, comprehension was significantly higher for participants who received the professional video consent (score increase=1.79; 95% CI 1.02-2.55) and

    Full Text Available This paper describes a prototype instrumentation system for photogrammetric measuring of bed and ash layers, as well as for flying particle detection and pursuit using a single device (CCD web camera. The system was designed to obtain images of the combustion process in the interior of a domestic boiler. It includes a cooling system, needed because of the high temperatures in the combustion chamber of the boiler. The cooling system was designed using CFD simulations to ensure effectiveness. This method allows more complete and real-time monitoring of the combustion process taking place inside a boiler. The information gained from this system may facilitate the optimisation of boiler processes.

    A state budget shortfall defunded 10 local tobacco coalitions during a randomized trial but defunded coalitions continued to have access to 2 technical assistance Web sites. To test the ability of Web-based technology to provide technical assistance to local tobacco control coalitions. 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

    Argonne National Laboratory has developed an Internet web site providing access to critical information needed to support decisions on the management and disposal of wastes containing naturally occurring radioactive material (NORM). The NORM Technology Connection web site provides current information on (1) service companies that provide support on NORM issues (e.g., site characterization and remediation, sample analysis, radiation safety training, disposal) and (2) existing applicable NORM regulations and guidelines. A third element of the site is an electronic mail list that allows users to post or respond to questions about the management of NORM. Development of the NORM Technology Connection web site was funded by the U.S. Department of Energy, Office of Fossil Energy. It is hosted and maintained by the Interstate Oil and Gas Compact Commission. The web site is publicly available; access is free, as is participation by any of the service companies.

    2002-01-01

    We present here the usability assessment study of a medical web site dedicated to the Cataloguing and Indexing of French speaking Medical web Sites (CISMeF). We performed a usability inspection using heuristic evaluation and an empirical usability test using a portable lab. The results of the heuristic evaluation show usability flaws along guidance, prompting and legibility ergonomic criteria. The usability test confirms this result and gives some more hints about the severity rating of the problems. From these results, we draw up a set of recommendations for the re-engineering of the Human Computer Interface (HCI). We conclude on the necessity to integrate usability engineering early enough in the projects lifecycle.

    2012-05-01

    Recommended readability of patient education materials is sixth-grade level or lower. Readability of 212 patient education materials pertaining to adult reconstruction topics available from the American Academy of Orthopaedic Surgeons, American Association of Hip and Knee Surgeons, and 3 other specialty and private practitioner Web sites was assessed using the Flesch-Kincaid grade formula. The mean Flesch-Kincaid score was 11.1 (range, 3-26.5). Only 5 (2%) articles had a readability level of sixth grade or lower. Readability of most of the articles for patient education on adult reconstruction Web sites evaluated may be too advanced for a substantial portion of patients. Further studies are needed to assess the optimal readability level of health information on the Internet. Copyright © 2012 Elsevier Inc. All rights reserved.

    2012-01-01

    The purpose of this study is to provide evidence for strategic planning regarding e-health development in U.S. hospitals. A content analysis of a representative sample of the U.S. hospital Web sites has revealed how U.S. hospitals have taken advantage of the 21 patient-oriented interactive tools identified in this study. Significant gaps between various types of hospitals have also been found. It is concluded that although the majority of the U.S. hospitals have adopted traditional functional tools, they need to make significant inroad in implementing the core e-business tools to serve their patients/users, making their Web sites more efficient marketing tools.

    2008-05-01

    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.

    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.

    Metals play vital roles in both the mechanism and architecture of biological macromolecules. Yet structures of metal-containing macromolecules where metals are misidentified and/or suboptimally modeled are abundant in the Protein Data Bank (PDB). This shows the need for a diagnostic tool to identify and correct such modeling problems with metal binding environments. The "CheckMyMetal" (CMM) web server (http://csgid.org/csgid/metal_sites/) is a sophisticated, user-friendly web-based method to evaluate metal binding sites in macromolecular structures in respect to 7350 metal binding sites observed in a benchmark dataset of 2304 high resolution crystal structures. The protocol outlines how the CMM server can be used to detect geometric and other irregularities in the structures of metal binding sites and alert researchers to potential errors in metal assignment. The protocol also gives practical guidelines for correcting problematic sites by modifying the metal binding environment and/or redefining metal identity in the PDB file. Several examples where this has led to meaningful results are described in the anticipated results section. CMM was designed for a broad audience—biomedical researchers studying metal-containing proteins and nucleic acids—but is equally well suited for structural biologists to validate new structures during modeling or refinement. The CMM server takes the coordinates of a metal-containing macromolecule structure in the PDB format as input and responds within a few seconds for a typical protein structure modeled with a few hundred amino acids.

    An increasing amount of health education resources for patients and professionals are distributed via social media channels. For example, thousands of health education videos are disseminated via YouTube. Often, tags are assigned by the disseminator. However, the lack of use of standardized terminologies in those tags and the presence of misleading videos make it particularly hard to retrieve relevant videos. i) Identify the use of standardized medical thesauri (SNOMED CT) in YouTube Health videos tags from preselected YouTube Channels and demonstrate an information technology (IT) architecture for treating the tags of these health (video) resources. ii) Investigate the relative percentage of the tags used that relate to SNOMED CT terms. As such resources may play a key role in educating professionals and patients, the use of standardized vocabularies may facilitate the sharing of such resources. iii) Demonstrate how such resources may be properly exploited within the new generation of semantically enriched content or learning management systems that allow for knowledge expansion through the use of linked medical data and numerous literature resources also described through the same vocabularies. We implemented a video portal integrating videos from 500 US Hospital channels. The portal integrated 4,307 YouTube videos regarding surgery as described by 64,367 tags. BioPortal REST services were used within our portal to match SNOMED CT terms with YouTube tags by both exact match and non-exact match. The whole architecture was complemented with a mechanism to enrich the retrieved video resources with other educational material residing in other repositories by following contemporary semantic web advances, in the form of Linked Open Data (LOD) principles. The average percentage of YouTube tags that were expressed using SNOMED CT terms was about 22.5%, while one third of YouTube tags per video contained a SNOMED CT term in a loose search; this analogy became one tenth in

    2010-12-01

    The increasing use of the Internet for gathering information regarding preventative health measures creates a unique dilemma. Access to the Internet is almost universal in the USA. Web sites presenting health information regarding breast cancer must create information that is understandable to the general public, meaning a reading level of around seventh grade. Text was obtained from the National Cancer Institute's Web site, and an examination of the text's grade level was performed. The text was written at between a 10th and 12th grade level. This indicates that information regarding breast cancer prevention obtained from the National Cancer Institute's web site is written at far too high of a level.

    2016-11-01

    Full Text Available In this paper, a study of the perceived destination image created by promotional Web Pages is expounded in an attempt to identify their differences as generators of destination image in the consumers’ mind. Specifically, it seeks to analyse whether the web sites of different Spanish regions improve the image that consumers have of the destination, identifying their main dimensions and analysing its effect on satisfaction and intentions of the future behaviour of potential visitors. To achieve these objectives and verify the hypotheses, a laboratory experiment was performed, where it was determined what changes are produced in the tourist´s previous image after browsing the tourist webs of three different regions. Moreover, it analyses the differences in the effect of the perceived image on satisfaction and potential visitors´ future behavioural intentions. The results obtained enable us to identify differences in the composition of the perceived image according to the destination, while confirming the significant effect of different perceived image dimensions regarding satisfaction. The results allow managers to gain a better understanding of the effectiveness of their sites from a consumer perspective as well as suggestions to follow in order to achieve greater efficiency in their communication actions in order to improve the motivation of visitors to go to the destination.

    Sites that show specific conservation patterns within subsets of proteins in a protein family are likely to be involved in the development of functional specificity. These sites, generally termed specificity determining sites (SDS), might play a crucial role in binding to a specific substrate or proteins. Identification of SDS through experimental techniques is a slow, difficult and tedious job. Hence, it is very important to develop efficient computational methods that can more expediently identify SDS. Herein, we present Specificity prediction using amino acids' Properties, Entropy and Evolution Rate (SPEER)-SERVER, a web server that predicts SDS by analyzing quantitative measures of the conservation patterns of protein sites based on their physico-chemical properties and the heterogeneity of evolutionary changes between and within the protein subfamilies. This web server provides an improved representation of results, adds useful input and output options and integrates a wide range of analysis and data visualization tools when compared with the original standalone version of the SPEER algorithm. Extensive benchmarking finds that SPEER-SERVER exhibits sensitivity and precision performance that, on average, meets or exceeds that of other currently available methods. SPEER-SERVER is available at http://www.hpppi.iicb.res.in/ss/.

    Banning, James H.; Sexton, Julie; Most, David E.; Maier, Shelby

    Photographs found in the search for and exploration of 13 university mining engineering department Web sites were studied for their asymmetries of power by analyzing the role (student, instructor, secretarial staff, miner, and honoree) and posture (sitting, standing) of men and women in the photographs. The Web site photographs showed a higher rate of women occupying student roles than men did. Women had a lower rate of occupying instructor and miner roles. No women were portrayed as being honored. Men exhibited a higher rate of occupying the standing posture than did women. Women were more often shown sitting than men were. Implications of portraying a nonequitable power structure between men and women in the search for and exploration of mining engineering Web sites are discussed, including a recommendation that all academic departments should examine the portrayal of gender on their Web sites.

  1. Has Retrieval Technology in Vertical Site Search Systems Improved over the Years? A Holistic Evaluation for Real Web Systems

    Directory of Open Access Journals (Sweden)

    Mandl, Thomas

    2015-12-01

    Full Text Available Evaluation of retrieval systems is mostly limited to laboratory settings and rarely considers changes of performance over time. This article presents an evaluation of retrieval systems for internal Web site search systems between the years 2006 and 2011. A holistic evaluation methodology for real Web sites was developed which includes tests for functionality, search quality, and user interaction. Among other sites, one set of 20 Web site search systems was evaluated three times in different years and no substantial improvement could be shown. It is surprising that the communication between site and user still leads to very poor results in many cases. Overall, the quality of these search systems could be improved, and several areas for improvement are apparent from our evaluation. For a comparison, Google’s site search function was also tested with the same tasks.

    The Draper Semianalytic Satellite Theory (DSST) is a semianalytic orbit propagator, which was carried out on Fortran to run from a command line interface. The construction of DSST began at the Computer Sciences Corporation and continued at the Draper Laboratory in the late 1970's and early 1980's. There are two versions of this application. One of them can be found as an option within the Goddard Trajectory Determination System (GTDS), whereas the other is available as a Standalone Orbit Propagator Package. Both versions are constantly evolving and updating. This constant evolution and updating allows DSST to take into account a wide variety of perturbation forces, which can be selected by means of a non-trivial options system at run time, and makes DSST a useful tool for performing short-term high accuracy orbit determination as well as long-term evolution. DSST has been included as part of an open source project for Space Situational Awareness and space object catalog work. On the last IAC 2011 a first step was taken in this sense and DSST was included on the tastrody Web-Site prototype [3, 4], which provided DSST with a friendly web interface, thus simplifying its use for both expert and non-expert users. However, this prototype has evolved into a stable platform based on the Drupal open source content management system (http://drupal.org Drupal), which simplifies the integration of our own application server. Drupal is supported by a large group of developers and users. Furthermore, a significant number of web-sites have been created using Drupal. In this work we present the integration of DSST in the new web-site, the new facilities provide by this platform to create the research community based on DSST and the comparison tests between the GTDS DSST, DSST Standalone and DSST Web version. These tests will be available in order to facilitate the user with better understanding of DSST. REFERENCES [1] J. G. Neelon, P. J. Cefola, and R. J. Proulx, Current

    Many people may search for information about tobacco use, the largest cause of preventable mortality in the United States, on the Internet. In 1999, Philip Morris U.S.A. (PM), the country's biggest cigarette manufacturer, posted a Web site and launched a campaign to encourage people to obtain information about tobacco and health issues there. The company asserted that its goal was to deliver the messages of the public health community about tobacco. However, internal tobacco company documents reveal that the site was a public relations effort intended to help the company avoid punishment and regulation. Examination of the language on the Web site reveals many contradictions and omissions that may undermine public health messages. Among these are vague and confusing information about addiction, tar, and nicotine, a lack of motivators to quit smoking, and silence about tobacco-related mortality. By appearing to join with public health organizations in disseminating "responsible" messages about tobacco, PM may improve its image, thus facilitating its ability to continue to sell its lethal products. Public health nurses should be prepared to examine health information on the Internet for subtle biases, to counter PM's specific language about smoking to patients, and to challenge PM's larger corporate goals.

    We assessed the nutritional quality of branded food and beverage products advertised on 28 Web sites popular with children. Of the 77 advertised products for which nutritional information was available, 49 met Institute of Medicine criteria for foods to avoid, 23 met criteria for foods to neither avoid nor encourage, and 5 met criteria for foods to encourage. There is a need for further research on the nature and extent of food and beverage advertising online to aid policymakers as they assess the impact of this marketing on children.

    2009-12-31

    Techniques for analyzing protein-DNA interactions on a genome-wide scale have recently established regulatory roles for distal enhancers. However, the large sizes of higher eukaryotic genomes have made identification of these elements difficult. Information regarding sequence conservation, exon annotation and repetitive regions can be used to reduce the size of the search region. However, previously developed resources are inadequate for consolidating such information. CONVIRT is a web resource for the identification of transcription factor binding sites and also features comparative genomics. Genomic information on ortholog-independent conserved regions, exons, repeats and sequences is integrated into the virtual chromosome, and statistically over-represented single or combinations of transcription factor binding sites are sought. CONVIRT provides regulatory network analysis for several organisms with long promoter regions and permits inter-species genome alignments. CONVIRT is freely available at http://biosoft.kaist. ac.kr/convirt.

    This study explored the association between sociosexuality (behavior, attitudes, and desire) and commitment to understand sexual infidelity in current relationships. We also explored how these variables were associated with attitudes toward infidelity. Participants were romantically involved heterosexuals (N = 252; 51 women, 201 men; Mage = 41.13, SD = 9.82) registered on a dating Web site directed at romantically involved individuals. Results showed that sociosexuality, alongside commitment, was associated with sexual infidelity. Individuals who had (versus had not) previously engaged in infidelity reported more unrestricted sociosexuality, while reporting less commitment. For individuals reporting prior sexual infidelity, unrestricted sociosexual desire and lesser commitment were associated with more permissive perceptions of infidelity. For individuals reporting no prior sexual infidelity, greater commitment was always associated with more strict perceptions of infidelity. No gender differences emerged in the analyses. Also, no differences were found according to individual motivations (i.e., looking to know other people versus seeking casual sex) or relational motivations (i.e., individual registration versus registration as a couple) underlying individuals' registration on the Web site. These results are an important addition to the literature on infidelity by analyzing a specific sample motivated to engage in infidelity. Implications for future research are discussed.

    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.

    2009-12-01

    Despite the increasing popularity of social networking Web sites (SNWs), very little is known about the psychosocial variables that predict people's use of these Web sites. The present study used an extended model of the theory of planned behavior (TPB), including the additional variables of self-identity and belongingness, to predict high-level SNW use intentions and behavior in a sample of young people ages 17 to 24 years. Additional analyses examined the impact of self-identity and belongingness on young people's addictive tendencies toward SNWs. University students (N = 233) completed measures of the standard TPB constructs (attitude, subjective norm, and perceived behavioral control), the additional predictor variables (self-identity and belongingness), demographic variables (age, gender, and past behavior), and addictive tendencies. One week later, they reported their engagement in high-level SNW use during the previous week. Regression analyses partially supported the TPB: attitude and subjective norm significantly predicted intentions to engage in high-level SNW use with intention significantly predicting behavior. Self-identity, but not belongingness, significantly contributed to the prediction of intention and, unexpectedly, behavior. Past behavior also significantly predicted intention and behavior. Self-identity and belongingness significantly predicted addictive tendencies toward SNWs. Overall, the present study revealed that high-level SNW use is influenced by attitudinal, normative, and self-identity factors, findings that can be used to inform strategies that aim to modify young people's high levels of use or addictive tendencies for SNWs.

    Physical inactivity levels are unacceptably high and effective interventions that can increase physical activity in large populations at low cost are urgently needed. Web-based interventions that use computer-tailoring have shown to be effective, though people tend to 'skim' and 'scan' text on the Internet rather than thoroughly read it. The use of online videos is, however, popular and engaging. Therefore, the aim of this 3-group randomised controlled trial is to examine whether a web-based physical activity intervention that provides personally-tailored videos is more effective when compared with traditional personally-tailored text-based intervention and a control group. In total 510 Australians will be recruited through social media advertisements, e-mail and third party databases. Participants will be randomised to one of three groups: text-tailored, video-tailored, or control. All groups will gain access to the same web-based platform and a library containing brief physical activity articles. The text-tailored group will additionally have access to 8 sessions of personalised physical activity advice that is instantaneously generated based on responses to brief online surveys. The theory-based advice will be provided over a period of 3 months and address constructs such as self-efficacy, motivation, goal setting, intentions, social support, attitudes, barriers, outcome expectancies, relapse prevention and feedback on performance. Text-tailored participants will also be able to complete 7 action plans to help them plan what, when, where, who with, and how they will become more active. Participants in the video-tailored group will gain access to the same intervention content as those in the text-tailored group, however all sessions will be provided as personalised videos rather than text on a webpage. The control group will only gain access to the library with generic physical activity articles. The primary outcome is objectively measured physical activity

    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.

    As active and passive surface wave methods are getting popular for evaluating site response of earthquake ground motion, demand on the development of database for investigation results is also increasing. Seismic ground motion not only depends on 1D velocity structure but also on 2D and 3D structures so that spatial information of S-wave velocity must be considered in ground motion prediction. The database can support to construct 2D and 3D underground models. Inversion of surface wave processing is essentially non-unique so that other information must be combined into the processing. The database of existed geophysical, geological and geotechnical investigation results can provide indispensable information to improve the accuracy and reliability of investigations. Most investigations, however, are carried out by individual organizations and investigation results are rarely stored in the unified and organized database. To study and discuss appropriate database and digital standard format for the surface wave investigations, we developed a prototype of web-based database to store observed data and processing results of surface wave investigations that we have performed at more than 400 sites in U.S. and Japan. The database was constructed on a web server using MySQL and PHP so that users can access to the database through the internet from anywhere with any device. All data is registered in the database with location and users can search geophysical data through Google Map. The database stores dispersion curves, horizontal to vertical spectral ratio and S-wave velocity profiles at each site that was saved in XML files as digital data so that user can review and reuse them. The database also stores a published 3D deep basin and crustal structure and user can refer it during the processing of surface wave data.

    2017-09-28

    The National Collaborating Centre for Methods and Tools (NCCMT) offers workshops and webinars to build public health capacity for evidence-informed decision-making. Despite positive feedback for NCCMT workshops and resources, NCCMT users found key terms used in research papers difficult to understand. The Understanding Research Evidence (URE) videos use plain language, cartoon visuals, and public health examples to explain complex research concepts. The videos are posted on the NCCMT website and YouTube channel. The first four videos in the URE web-based video series, which explained odds ratios (ORs), confidence intervals (CIs), clinical significance, and forest plots, were evaluated. The evaluation examined how the videos affected public health professionals' practice. A mixed-methods approach was used to examine the delivery mode and the content of the videos. Specifically, the evaluation explored (1) whether the videos were effective at increasing knowledge on the four video topics, (2) whether public health professionals were satisfied with the videos, and (3) how public health professionals applied the knowledge gained from the videos in their work. A three-part evaluation was conducted to determine the effectiveness of the first four URE videos. The evaluation included a Web-based survey, telephone interviews, and pretest and posttests, which evaluated public health professionals' experience with the videos and how the videos affected their public health work. Participants were invited to participate in this evaluation through various open access, public health email lists, through informational flyers and posters at the Canadian Public Health Association (CPHA) conference, and through targeted recruitment to NCCMT's network. In the Web-based surveys (n=46), participants achieved higher scores on the knowledge assessment questions from watching the OR (P=.04), CI (P=.04), and clinical significance (P=.05) videos but not the forest plot (P=.12) video, as

    Sequence feature annotations (e.g., protein domain boundaries, binding sites, and secondary structure predictions) are an essential part of biological research. Annotations are widely used by scientists during research and experimental design, and are frequently the result of biological studies. A generalized and simple means of disseminating and visualizing these data via the web would be of value to the research community. Mason is a web site widget designed to visualize and compare annotated features of one or more nucleotide or protein sequence. Annotated features may be of virtually any type, ranging from annotating transcription binding sites or exons and introns in DNA to secondary structure or domain boundaries in proteins. Mason is simple to use and easy to integrate into web sites. Mason has a highly dynamic and configurable interface supporting multiple sets of annotations per sequence, overlapping regions, customization of interface and user-driven events (e.g., clicks and text to appear for tooltips). It is written purely in JavaScript and SVG, requiring no 3(rd) party plugins or browser customization. Mason is a solution for dissemination of sequence annotation data on the web. It is highly flexible, customizable, simple to use, and is designed to be easily integrated into web sites. Mason is open source and freely available at https://github.com/yeastrc/mason.

    Recently, the role of reputation information in on-line discussion groups and review sites has received much attention, and that has spurred a great deal of research on sentiment analysis of web documents. It is well known that collecting sentiment expressions, which tend to be domain-dependent, is useful for sentiment analysis. However, it can be prohibitively costly to manually collect expressions for each domain. The purpose of this paper is to propose an automatic method to acquire sentiment expressions on a specific subject from web documents. Our approach is based on a characteristic of sentiment expressions that often appear with their sentiment causes and both of them have cause-and-effect relationships. We develop a technique for recognizing cause-and-effect relationships between sentiment expressions and their sentiment causes using the results of dependency structure analysis. The proposed method uses this technique to extract sentiment causes starting from a small set of seed sentiment expressions, and extracts sentiment expressions from a set of sentiment causes. To evaluate this work, we conducted experiments using discussion board messages about hotels and sweets. The results demonstrate that the proposed method effectively extract diversified sentiment expressions relevant to each domain and possesses adequate precision. Precision is also found to be better for compound sentiment expressions.

    1998-09-01

    Since its inception, the world wide web (WWW) has possessed the potential for becoming a 'watershed' medium for conveying complex, structured information across vast temporal and geographical barriers. In 1995, the MedWorld project (http:(/)/medworld.stanford.edu) was created at the Stanford University School of Medicine in an effort to innovate and explore the design process of creating WWW applications specifically for medical education. Until recently, the evolution of WWW applications has been mainly driven by technological advances in client-server technology, enabling or translating traditional modes of collaborative medical education (e.g. voice, presence, print, motion) into WWW devices and applications. Many of these applications, while technologically advanced, lack focused development of interface and interactivity design, which may enhance learning experiences. WWW applications which incorporate design innovation in parity with advances in client-server technology have been termed, 'third generation' web sites and have the potential to improve the quality of WWW applications designed for medical education. This work describes how the MedWorld project has created a 'third generation' WWW application by utilizing innovation in information, interface and interactivity design to create innovative WWW technology for the medical education arena.

    The pro-anorexia community has emerged as a powerful cultural movement that takes an at least partially positive attitude toward anorexia nervosa and other eating disorders. A systematic review of the literature on pro-ana forums focused specifically on females with eating disorders. However, epidemiological data suggest that as much as 25% of the eating disorders population is male. In our review of pro-anorexia web sites, we found a substantial number of participants were male. We conducted a qualitative content analysis of male participation in pro-ana forums in an effort to learn more about male participation in these forums. In this article, we present the results of this analysis, highlighting themes of social support, community appreciation, and ambivalence, as well as themes that appear to be particular to the male experience of eating disorders, such as alienation and teasing.

    A web site dedicated to Mars Mineral Spectroscopy has been established at http://www.mtholyoke.edu/go/mars. Its goal is to provide an easily accessible data set of Mossbauer spectra of minerals collected over a range of temperatures, to provide suitable analog spectra for data acquired on remote surfaces such as Mars. Complementing these data (eventually) will be both reflectance FTIR data, collected at Brown University's RELAB facility, and Raman spectra to be collected by Jill Pasteris at Washington University St. Louis. Through our Education link, we provide information for those wishing to learn about how Mossbauer and other types of spectroscopy work. Our emphasis is to study only well-characterized mineral samples that represent typical rock-forming occurrences such as might exist on Mars and other terrestrial bodies in our solar system.

  8. A Queer Theorist's Critique of Online Domestic Violence Advocacy: Critically Responding to the National Coalition Against Domestic Violence Web Site.

    Shelton, Samuel Z

    2017-08-30

    Since the foundations of the contemporary anti-violence movement in the 1960s and 1970s, advocates have sought to establish a critical understanding of domestic violence that we can use to direct our efforts for social change. Yet many advocates and advocacy organizations continue to rely on a problematic narrative of sameness that marginalizes and erases diverse victims' experiences and needs. In this article, I conduct a critical discourse analysis of the National Coalition Against Domestic Violence Web site to identify outcomes of this narrative for the inclusivity of advocacy efforts. I argue that despite the organization's numerous claims to represent diverse victims' experiences, Web site content reveals that its purportedly general account of domestic violence normalizes the experiences of a small group of victims-namely, heterosexual, cisgender women. Further, the Web site's content greatly limits the potential for thinking about and discussing violence across difference. I conclude with recommendations for changes in advocacy practices.

    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.

    Americans are spending an increasing amount of time using "new media" like the Internet. There has been little research examining food and beverage Web sites' content and marketing practices, especially those that attract children and adolescents. The purpose of this study was to conduct a content analysis of food- and beverage-brand Web sites and the marketing techniques and advertising strategies present on these sites. The top five brands in eight food and beverage categories, 40 brands in total, were selected based on annual sales data from Brandweek magazine's annual "Superbrands" report. Data were collected using a standardized coding form. The results show a wide variety of Internet marketing techniques and advertising strategies targeting children and adolescents. "Advergaming" (games in which the advertised product is part of the game) was present on 63% of the Web sites. Half or more of the Web sites used cartoon characters (50%) or spokescharacters (55%), or had a specially designated children's area (58%) with a direct link from the homepage. With interactive media still in its developmental stage, there is a need to develop safeguards for children. Food and nutrition professionals need to advocate for responsible marketing techniques that will support the health of children.

    The Home Energy Saver (HES, http://HomeEnergySaver.lbl.gov) is an interactive web site designed to help residential consumers make decisions about energy use in their homes. This report describes the underlying methods and data for estimating energy consumption. Using engineering models, the site estimates energy consumption for six major categories (end uses); heating, cooling, water heating, major appliances, lighting, and miscellaneous equipment. The approach taken by the Home Energy Saver is to provide users with initial results based on a minimum of user input, allowing progressively greater control in specifying the characteristics of the house and energy consuming appliances. Outputs include energy consumption (by fuel and end use), energy-related emissions (carbon dioxide), energy bills (total and by fuel and end use), and energy saving recommendations. Real-world electricity tariffs are used for many locations, making the bill estimates even more accurate. Where information about the house is not available from the user, default values are used based on end-use surveys and engineering studies. An extensive body of qualitative decision-support information augments the analytical results.

    Full Text Available Over half of the Australian population does not meet physical activity guidelines and has an increased risk of chronic disease. Web-based physical activity interventions have the potential to reach large numbers of the population at low cost, however issues have been identified with usage and participant retention. Personalised (computer-tailored physical activity advice delivered through video has the potential to address low engagement, however it is unclear whether it is more effective in engaging participants when compared to text-delivered personalised advice. This study compared the attention and recall outcomes of tailored physical activity advice in video- versus text-format. Participants (n=41 were randomly assigned to receive either video- or text-tailored feedback with identical content. Outcome measures included attention to the feedback, measured through advanced eye-tracking technology (Tobii 120, and recall of the advice, measured through a post intervention interview. Between group ANOVA’s, Mann-Whitney U tests and Chi square analyses were applied. Participants in the video-group displayed greater attention to the physical activity feedback in terms of gaze-duration on the feedback (7.7 min vs. 3.6 min, p< 001, total fixation-duration on the feedback (6.0 min vs. 3.3 min, p< 001, and focusing on feedback (6.8 vs. 3.5 min, p< 001. Despite both groups having the same ability to navigate through the feedback, the video-group completed a significantly (p< .001 higher percentage of feedback sections (95% compared to the text-group (66%. The main messages were recalled in both groups, but many details were forgotten. No significant between group differences were found for message recall. These results suggest that video-tailored feedback leads to greater attention compared to text-tailored feedback. More research is needed to determine how message recall can be improved, and whether video-tailored advice can lead to greater health

    2015-03-01

    Self-evaluation and peer-feedback are important strategies within the reflective practice paradigm for the development and maintenance of professional competencies like medical communication. Characteristics of the self-evaluation and peer-feedback annotations of medical students' video recorded communication skills were analyzed. Twenty-five year 4 medical students recorded history-taking consultations with a simulated patient, uploaded the video to a web-based platform, marked and annotated positive and negative events. Peers reviewed the video and self-evaluations and provided feedback. Analyzed were the number of marked positive and negative annotations and the amount of text entered. Topics and specificity of the annotations were coded and analyzed qualitatively. Students annotated on average more negative than positive events. Additional peer-feedback was more often positive. Topics most often related to structuring the consultation. Students were most critical about their biomedical topics. Negative annotations were more specific than positive annotations. Self-evaluations were more specific than peer-feedback and both show a significant correlation. Four response patterns were detected that negatively bias specificity assessment ratings. Teaching students to be more specific in their self-evaluations may be effective for receiving more specific peer-feedback. Videofragmentrating is a convenient tool to implement reflective practice activities like self-evaluation and peer-feedback to the classroom in the teaching of clinical skills.

    A simplified narrow-band imaging (NBI) endoscopy classification of gastric precancerous and cancerous lesions was derived and validated in a multicenter study. This classification comes with the need for dissemination through adequate training. To address the learning curve of this classification by endoscopists with differing expertise and to assess the feasibility of a YouTube-based learning program to disseminate it. Prospective study. Five centers. Six gastroenterologists (3 trainees, 3 fully trained endoscopists [FTs]). Twenty tests provided through a Web-based program containing 10 randomly ordered NBI videos of gastric mucosa were taken. Feedback was sent 7 days after every test submission. Measures of accuracy of the NBI classification throughout the time. From the first to the last 50 videos, a learning curve was observed with a 10% increase in global accuracy, for both trainees (from 64% to 74%) and FTs (from 56% to 65%). After 200 videos, sensitivity and specificity of 80% and higher for intestinal metaplasia were observed in half the participants, and a specificity for dysplasia greater than 95%, along with a relevant likelihood ratio for a positive result of 7 to 28 and likelihood ratio for a negative result of 0.21 to 0.82, were achieved by all of the participants. No constant learning curve was observed for the identification of Helicobacter pylori gastritis and sensitivity to dysplasia. The trainees had better results in all of the parameters, except specificity for dysplasia, compared with the FTs. Globally, participants agreed that the program's structure was adequate, except on the feedback, which should have consisted of a more detailed explanation of each answer. No formal sample size estimate. A Web-based learning program could be used to teach and disseminate classifications in the endoscopy field. In this study, an NBI classification for gastric mucosal features seems to be easily learned for the identification of gastric preneoplastic

    Do you use video in your teaching? Do you make your own video? Interested in joining our growing community of geoscience educators designing and using video inside and outside the classroom? Over four months in Spring 2014, 22 educators of varying video design and development expertise participated in an NSF-funded On the Cutting Edge virtual workshop to review the best educational research on video design and use; to share video-development/use strategies and experiences; and to develop a website of resources for a growing community of geoscience educators who use video: http://serc.carleton.edu/NAGTWorkshops/video/workshop2014/index.html. The site includes links to workshop presentations, teaching activity collections, and a growing collection of online video resources, including "How-To" videos for various video editing or video-making software and hardware options. Additional web resources support several topical themes including: using videos to flip classes, handling ADA access and copyright issues, assessing the effectiveness of videos inside and outside the classroom, best design principles for video learning, and lists and links of the best videos publicly available for use. The workshop represents an initial step in the creation of an informal team of collaborators devoted to the development and support of an ongoing network of geoscience educators designing and using video.

    2017-08-29

    Recent legislation in states across the United States has required governmental health agencies to take on new and different roles in relation to abortion. While there has been media attention to health department roles in regulating abortion providers, there has been no systematic investigation of the range of activities in which state and local health departments are engaged. To systematically investigate health department activities related to abortion. We searched state health department Web sites of the 50 states and District of Columbia using key words such as "abortion" and "pregnancy termination". Two trained coders categorized 6093 documents using the 10 Essential Public Health Services (EPHS) framework. We then applied these methods to 671 local health department documents. State and local health department Web sites. N/A. On average, states engaged in 5.1 of 10 Essential Services related to abortion. Most (76%-98%) state health departments engaged in activities to Monitor Health Status (EPHS1), Enforce Laws (EPHS6), and Evaluate Effectiveness, Accessibility, and Quality (EPHS9). Many (47%-69%) engaged in activities to Inform and Educate (EPHS3), Develop Policies (EPHS5), and Link to Services (EPHS7). A minority (4%-29%) engaged in activities to Diagnose and Investigate Health Problems (EPHS2), Mobilize Community Partnerships (EPHS4), and Assure Competent Workforce (EPHS8). No state engaged in Innovative Research (EPHS10). Few local health departments engaged in abortion-related activities. While most state health departments engage in abortion-related activities, they appear to reflect what the law requires rather than the range of core public health activities. Additional research is needed to assess whether these services meet quality standards for public health services and determine how best to support governmental health agencies in their growing tasks. These findings raise important questions about the role of public health agencies and

  7. Improving the snow physics of WEB-DHM and its point evaluation at the SnowMIP sites

    Directory of Open Access Journals (Sweden)

    M. Shrestha

    2010-12-01

    Full Text Available In this study, the snow physics of a distributed biosphere hydrological model, referred to as the Water and Energy Budget based Distributed Hydrological Model (WEB-DHM is significantly improved by incorporating the three-layer physically based energy balance snowmelt model of Simplified Simple Biosphere 3 (SSiB3 and the Biosphere-Atmosphere Transfer Scheme (BATS albedo scheme. WEB-DHM with improved snow physics is hereafter termed WEB-DHM-S. Since the in-situ observations of spatially-distributed snow variables with high resolution are currently not available over large regions, the new distributed system (WEB-DHM-S is at first rigorously tested with comprehensive point measurements. The stations used for evaluation comprise the four open sites of the Snow Model Intercomparison Project (SnowMIP phase 1 with different climate characteristics (Col de Porte in France, Weissfluhjoch in Switzerland, Goose Bay in Canada and Sleepers River in USA and one open/forest site of the SnowMIP phase 2 (Hitsujigaoka in Japan. The comparisons of the snow depth, snow water equivalent, surface temperature, snow albedo and snowmelt runoff at the SnowMIP1 sites reveal that WEB-DHM-S, in general, is capable of simulating the internal snow process better than the original WEB-DHM. Sensitivity tests (through incremental addition of model processes are performed to illustrate the necessity of improvements over WEB-DHM and indicate that both the 3-layer snow module and the new albedo scheme are essential. The canopy effects on snow processes are studied at the Hitsujigaoka site of the SnowMIP2 showing that the snow holding capacity of the canopy plays a vital role in simulating the snow depth on ground. Through these point evaluations and sensitivity studies, WEB-DHM-S has demonstrated the potential to address basin-scale snow processes (e.g., the snowmelt runoff, since it inherits the distributed hydrological framework from the WEB-DHM (e.g., the slope-driven runoff

    2007-05-01

    Full Text Available Abstract Background The nucleotide sequence flanking the translation initiation codon (start codon context affects the translational efficiency of eukaryotic mRNAs, and may indicate the presence of an alternative translation initiation site (TIS to produce proteins with different properties. Multi-targeting may reflect the translational variability of these other protein forms. In this paper we present a web server that performs computations to investigate the usage of alternative translation initiation sites for the synthesis of new protein variants that might have different functions. Results An efficient web-based tool entitled TISs-ST (Translation Initiation Sites and Secretory Targets evaluates putative translation initiation sites and indicates the prediction of a signal peptide of the protein encoded from this site. The TISs-ST web server is freely available to both academic and commercial users and can be accessed at http://ipe.cbmeg.unicamp.br/pub/TISs-ST. Conclusion The program can be used to evaluate alternative translation initiation site consensus with user-specified sequences, based on their composition or on many position weight matrix models. TISs-ST provides analytical and visualization tools for evaluating the periodic frequency, the consensus pattern and the total information content of a sequence data set. A search option allows for the identification of signal peptides from predicted proteins using the PrediSi software.

    Full Text Available Recent major political uprisings are indicating the extent to which social learning Web 2.0 technologies, can infl uence change in informal learning settings. Recognition and a discussion of the potential of that infl uence in formal learning settings have only just begun. This article describes a study of an international distance learning project in 2004, using a variety of Web 2.0 technologies, including video-based web conferencing, that sought to initiate and respond to this urgent need for dialogue in the research. Self-selected participants took part in a 5-week English as a foreign language (EFL program, a joint NATO sponsored Canadian and Romanian Ministry of Defense-supported initiative. Clear evidence of linguistic knowledge construction and of important changes to participants’ learner identities, indicates the power of these technologies to support the kind of learning that can lead to the development of global citizens and the skills they will increasingly require in the 21st century.

But, Internet also has proportionate opportunities to appear new intermediaries in the new hotel value chain (Connolly et al., 1998. A substantial portion of online room reservations continues to be accounted by the third-party Web sites (Law and Cheung, 2006. Hotels have been actively involved in multi-channel distribution in order to sell products and services more efficiently using a combination of traditional and electronic channels. It is important for organizations to rely on the channels that best match the organizational goals (O’Connor and Frew, 2004.The methodology for the experiment follows Statistical Design of Experiments (SDE. SDE is a statistical technique useful for developing, improving and optimizing processes and also has important applications in research into customer psychology and behaviour (Rosenbaum 1999. However, SDE is not a new tool in marketing; pioneering works such as those by Holland and Cravens (1973, Chevalier (1975 and more recently those of Starkey, Aughton and Brewin (1997, Almquist y Wyner (2001 have used full factorials and fractional factorial designs.

    2012-05-01

    To analzye adolescents' profiles on MyLol.net, a teen dating Web site, for risk content. We hypothesized that risk content would vary by age and gender. We selected and coded 752 publicly viewable profiles of adolescents aged 14-18 years for the following five risks: sex, alcohol, drugs, cigarettes, and violence. Of the total profiles, 27.7% contained risk-related content: 15.8% sexual behavior, 13.8% alcohol use, 1.6% drug use, 6.8% cigarette smoking, and .9% violence activity. Being female, "single" relationship status, and use of profanity (p < .05) were associated with risk content. Females' profiles were most likely to include risky content, especially sexual content. Adolescent females who have internalized social norms that place a high value on female sexuality may reflect this in their online profiles. Online mention of interest/involvement in risky behavior may have negative consequences (e.g., cyberbullies and sexual predators). Stronger universal Internet policies and education are needed to help protect adolescents. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    The electronic version of the γ-Ray Spectrum Catalogue, at the Web Site http://id.inel.gov/gamma/, has been extended to include additional radionuclides measured with modern Ge detectors. The set of data for each nuclide includes a new spectral plot, a complete decay scheme, and a table of γ-ray energies and intensities downloaded from the Evaluated Nuclear Structure Data File (ENSDF). Each γ-ray is color coded in the same way in each of these three presentations. γ rays from daughter activities are identified in the spectrum by labeling the peak with the isotope with which it belongs. X-rays, artifact peaks (e.g., sum peaks), and contaminant radionuclides are distinctly colored. For each available nuclide, any available spectra from the earlier NaI(Tl) and Ge(Li) Catalogues have been included. The date of all of the downloaded ENSDF data is also recorded to provide a pedigree. Actinide decay chains allow hot links to other members of the decay chain. Links to other user information resources have been included.

    2016-01-01

    Cellular mRNAs are predominantly translated in a cap-dependent manner. However, some viral and a subset of cellular mRNAs initiate their translation in a cap-independent manner. This requires presence of a structured RNA element, known as, Internal Ribosome Entry Site (IRES) in their 5′ untranslated regions (UTRs). Experimental demonstration of IRES in UTR remains a challenging task. Computational prediction of IRES merely based on sequence and structure conservation is also difficult, particularly for cellular IRES. A web server, IRESPred is developed for prediction of both viral and cellular IRES using Support Vector Machine (SVM). The predictive model was built using 35 features that are based on sequence and structural properties of UTRs and the probabilities of interactions between UTR and small subunit ribosomal proteins (SSRPs). The model was found to have 75.51% accuracy, 75.75% sensitivity, 75.25% specificity, 75.75% precision and Matthews Correlation Coefficient (MCC) of 0.51 in blind testing. IRESPred was found to perform better than the only available viral IRES prediction server, VIPS. The IRESPred server is freely available at http://bioinfo.net.in/IRESPred/. PMID:27264539

    2008-02-01

    Video streaming technology enables video content, held on the web sites, to be streamed via the web. We report the implementation and evaluation of video streaming in an undergraduate nursing program in a metropolitan university in Australia. Students (n=703) were emailed a survey with a 15% response rate. We found that 91% (n=74) of respondents stated that video streaming assisted their learning. Forty-six percent(n=50) of students had difficulty accessing video streaming (particularly at the beginning of the study period). Over a 97-day period there were 8440 "hits" to the site from 1039 different internet protocol (IP) addresses. There were 4475 video streaming sessions undertaken by users. Video streaming was used for reviewing previously attended lectures (52%, n=56), examination preparation (34%, n=37), viewing missed lectures (27%, n=29) and class preparation (9%, n=10). Our experience with the introduction of video streaming has met with general enthusiasm from both students and teaching staff. Video streaming has particular relevance for rural students.

    Mass media play an important role in the socialization of youth. Given its expanding nature and accessibility, the Internet may be at the forefront of this education. However, the extent of the Internet's impact on adolescent sexual attitudes and behaviors is not yet known. A total of 433 adolescents completed an anonymous survey at a health center in New York City. The cross-sectional survey assessed Internet accessibility, exposure to sexually explicit Web sites (SEWs), sexual behaviors, and sexually permissive attitudes. Of the participants, 96% had Internet access, and 55.4% reported ever visiting a SEW. Logistic regression analyses revealed that adolescents exposed to SEWs were more likely to have multiple lifetime sexual partners (OR=1.8, CI=1.2, 2.9), to have had more than one sexual partner in the last 3 months (OR=1.8, CI=1.1, 3.1), to have used alcohol or other substances at last sexual encounter (OR=2.8, CI=1.5, 5.2), and to have engaged in anal sex (OR=2.0, CI=1.2, 3.4). Adolescents who visit SEWs display higher sexual permissiveness scores compared with those who have never been exposed (2.3 vs. 1.9, p Internet pornography has potential implications for adolescent sexual relationships, such as number of partners and substance use. SEWs can serve an educational purpose and create an opportunity for adults to engage adolescents in discussions about sexual health and consumption of Internet material. Longitudinal research is needed to evaluate how exposure to SEWs influences youth attitudes and sexual behaviors.

    As healthcare consumers increasingly use the Internet as a source for health information, direct-to-consumer (DTC) prescription drug advertising online merits additional attention. The purpose of this research was to investigate media coverage of the joint marketing program linking the movie Happy Feet and the nonbranded disease education Web site FluFacts-a resource from Tamiflu flu treatment manufacturer Roche Laboratories Inc. Twenty-nine articles (n = 29) were found covering the Happy Feet-FluFacts marketing campaign. A coding guide was developed to assess elements of the articles, including those common in the sample and information that ideally would be included in these articles. Two coders independently coded the articles, achieving intercoder agreement of κ = 0.98 before resolving disagreements to arrive at a final dataset. The majority of articles reported that Roche operated FluFacts (51.7%) and mentioned the product Tamiflu (58.6%). Almost half (48.3%) reported FluFacts was an educational resource; yet, no articles mentioned other antiviral medications or nonmedical options for preventing the flu. Almost a quarter of the articles (24.1%) provided a call to action-telling readers to visit FluFacts or providing a link for them to do so. Findings suggest that journalists' coverage of this novel campaign-likely one of the goals of the campaign-helped spread the message of the Happy Feet-FluFacts relationship, often omitting other useful health information. Additional research is needed to better understand online DTC campaigns and how consumers react to these campaigns and resulting media coverage and to inform the policymakers' decisions regarding DTC advertising online.

    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.

    MyPyramid.gov, a major national Web site about healthful eating and physical activity, was analyzed for literacy, cultural, and linguistic factors relevant to consumers. The assessment used 4 standardized readability tests, 1 navigational test, availability of non-English content, and new criteria for cultural factors. Readability scores averaged between grade levels 8.8 and 10.8, and half the navigation criteria were met. The Web site was available in Spanish, but it had little cultural tailoring for English speakers. It is recommended that MyPyramid's readability, navigation, and cultural tailoring be improved. References are provided to help educators learn more about assessing and using Internet communication with diverse audiences.

    Although complementary and alternative medicine [CAM] is a term commonly used to denote practices that lie beyond the dominant medical orthodoxy, these practices are penetrating Israeli medical institutions. The purpose of the study was to evaluate CAM information on medical institutions' web sites in relation to the type of information considered to be significant by integrative physicians. The methods employed included evaluating CAM information on the websites of: all four health insurance agencies, the eleven largest hospitals in Israel, the Ministry of Health, and the Israeli Medical Association. This data was compared to the primary and most meaningful information stressed by integrative physicians at their conferences and work-meetings. The information on the insurance agencies' web sites is extensive and prominent, while on the other sites it is more concise and less prominent. A total of 31 diverse CAM methods are mentioned on all healthcare websites, while the Ministry of Health site mentions only four of them. Most sites list only advantages or drawbacks of these methods. Research findings on efficacy and safety, and information on the ethics and legality of CAM practitioners is virtually almost non-existent. While CAM is portrayed on some of the healthcare organizations' websites as an attractive commodity, on others it is presented as a separate area to be kept under biomedical scrutiny. One would expect healthcare institutions and the Ministry of Health to provide the public with balanced and sufficient information to enable patients to make informed choices and facilitate better integration of CAM with conventional treatments.

    2009-11-12

    New types of social Internet applications (often referred to as Web 2.0) are becoming increasingly popular within higher education environments. Although developed primarily for entertainment and social communication within the general population, applications such as blogs, social video sites, and virtual worlds are being adopted by higher education institutions. These newer applications differ from standard Web sites in that they involve the users in creating and distributing information, hence effectively changing how the Web is used for knowledge generation and dispersion. Although Web 2.0 applications offer exciting new ways to teach, they should not be the core of instructional planning, but rather selected only after learning objectives and instructional strategies have been identified. This paper provides an overview of prominent Web 2.0 applications, explains how they are being used within education environments, and elaborates on some of the potential opportunities and challenges that these applications present.

    While pharmaceutical companies provide abundant health and medical information on their Web sites, little is known about consumers' perceptions of pharmaceutical companies as a health information source and the impact of pharmaceutical Web sites on health-related attitudes and behaviors. Findings from this study suggest that a pharmaceutical company can be perceived to be just as credible as a government health agency, and that Web site interactivity and consumer involvement with online health information affect the persuasive effects of the pharmaceutical company's message. Implications for future research and for the role of pharmaceutical companies in health communication are discussed.

    Cancer centre Web sites can be a useful tool for distributing information about the benefits of physical activity for breast cancer (bca) survivors, and they hold potential for supporting health behaviour change. However, the extent to which cancer centre Web sites use evidence-based behaviour change techniques to foster physical activity behaviour among bca survivors is currently unknown. The aim of our study was to evaluate the presentation of behaviour-change techniques on Canadian cancer centre Web sites to promote physical activity behaviour for bca survivors. All Canadian cancer centre Web sites ( n = 39) were evaluated by two raters using the Coventry, Aberdeen, and London-Refined (calo-re) taxonomy of behaviour change techniques and the eEurope 2002 Quality Criteria for Health Related Websites. Descriptive statistics were calculated. The most common behaviour change techniques used on Web sites were providing information about consequences in general (80%), suggesting goal-setting behaviour (56%), and planning social support or social change (46%). Overall, Canadian cancer centre Web sites presented an average of M = 6.31 behaviour change techniques (of 40 that were coded) to help bca survivors increase their physical activity behaviour. Evidence of quality factors ranged from 90% (sites that provided evidence of readability) to 0% (sites that provided an editorial policy). Our results provide preliminary evidence that, of 40 behaviour-change techniques that were coded, fewer than 20% were used to promote physical activity behaviour to bca survivors on cancer centre Web sites, and that the most effective techniques were inconsistently used. On cancer centre Web sites, health promotion specialists could focus on emphasizing knowledge mobilization efforts using available research into behaviour-change techniques to help bca survivors increase their physical activity.

    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)

    To assess patients' usage of the Internet as a source of personal healthcare information and patients' perceptions of usefulness and content preferences of more locally focused online health-related material. A paper-based survey was undertaken by a convenience sample of cardiac outpatients. Age, gender, Internet access, Internet usage, perception of usefulness of online information, predicted intention to use a local cardiology Web site if available, and preferred components to be included were recorded. Univariate and bivariate statistics were used. Two hundred thirty-seven patients responded (62.1% males). One hundred seventy-six (74.3%) used the Internet, with 126 (63%) using it daily. For patients who did not have direct access to the Internet, 26 (50%) had a family member to do this on their behalf. Thus, the majority of patients (202 [85%]) had access to the Internet at home or someone who could access it on their behalf. Internet usage declined with age (Kendall's tau_b=0.321, p<0.001). There was no difference in use with gender (p=0.235). There was considerable interest expressed in a locally delivered Web-based information service. Online healthcare information services have the potential to reach the vast majority of cardiac patients either directly or through family support. The most elderly patients are less likely to use these services. Despite apparent satisfaction with existing online resources, there appears to be an unmet need for more information and considerable support for a locally based cardiac patient Web resource to deliver this. These findings may help guide future patient information Web site redesign.

    Protein-peptide interactions play essential functional roles in living organisms and their structural characterization is a hot subject of current experimental and theoretical research. Computational modeling of the structure of protein-peptide interactions is usually divided into two stages: prediction of the binding site at a protein receptor surface, and then docking (and modeling) the peptide structure into the known binding site. This paper presents a comprehensive CABS-dock method for the simultaneous search of binding sites and flexible protein-peptide docking, available as a user's friendly web server. We present example CABS-dock results obtained in the default CABS-dock mode and using its advanced options that enable the user to increase the range of flexibility for chosen receptor fragments or to exclude user-selected binding modes from docking search. Furthermore, we demonstrate a strategy to improve CABS-dock performance by assessing the quality of models with classical molecular dynamics. Finally, we discuss the promising extensions and applications of the CABS-dock method and provide a tutorial appendix for the convenient analysis and visualization of CABS-dock results.

    The grazing activities of phagotrophic protists on various microbial assemblages play key roles in determining the amount of carbon available for higher trophic levels and for export out of the photic zone. However, comparisons of the proportion of carbon consumed from the phytoplankton (cyanobacteria+photosynthetic eukaryotes) and heterotrophic bacteria (bacteria+archaea, excluding cyanobacteria) are rare. In this study, microbial community composition, phytoplankton growth and mortality rates (total chlorophyll a, Synechococcus, Prochlorococcus, and photosynthetic picoeukaryotes), and bacterial mortality rates were measured seasonally from 2012 to 2014 in the surface waters of three environmentally distinct sites in the San Pedro Channel, off the coast of southern CA, USA. Higher nutrient concentrations at the nearshore site supported community standing stocks that were 1.3-4.5x those found offshore, yet average growth and grazing rates of the phytoplankton and bacterial assemblages were generally similar between sites and across seasons. Thus, the amount of carbon consumed by the grazer assemblage was largely dictated by prey standing stocks. Heterotrophic bacteria constituted an important source of carbon for microbial consumers, particularly at the two offshore sites where bacterial carbon consumed was roughly equivalent to the amount of phytoplankton carbon consumed. Carbon removal by grazers at the nearshore station was predominantly from the diatoms, which were the primary component of the photosynthetic community at that site. This study highlights the significant contribution of protistan-bacterial trophic interactions to planktonic food webs and provides unique community composition and turnover data to inform biogeochemical models.

    Cancer patients want access to reliable information about currently recruiting clinical trials. Oncologists and their patients were randomly assigned to access a consumer-friendly cancer clinical trials web site [Australian Cancer Trials (ACT), www.australiancancertrials.gov.au] or to usual care in a cluster randomized controlled trial. The primary outcome, measured from audio recordings of oncologist-patient consultations, was the proportion of patients with whom participation in any clinical trial was discussed. Analysis was by intention-to-treat accounting for clustering and stratification. Thirty medical oncologists and 493 patients were recruited. Overall, 46% of consultations in the intervention group compared with 34% in the control group contained a discussion about clinical trials (P=0.08). The mean consultation length in both groups was 29 min (P=0.69). The proportion consenting to a trial was 10% in both groups (P=0.65). Patients' knowledge about randomized trials was lower in the intervention than the control group (mean score 3.0 versus 3.3, P=0.03) but decisional conflict scores were similar (mean score 42 versus 43, P=0.83). Good communication between patients and physicians is essential. Within this context, a web site such as Australian Cancer Trials may be an important tool to encourage discussion about clinical trial participation.

    Full Text Available In promoting the use of Information and Communication Technology (ICT in order to improve efficiency and effectiveness of government service institutions, the Government of Indonesia issued Presidential Instruction No. 3 of 2003 on e-Government. The directive requested that all government institutions in Indonesia should take advantage of ICT to improve public services. In line with this, the Ministry of Agriculture has launched several efforts to support the implementation of Presidential Instruction. One of these efforts is the implementation of the Web Site Competition between Work units under the Ministry. The contest has been held since 2004. The participants were grouped into three categories: 1. Directorate General / Agency 2. Provincial Agricultural Office 3. District Agriculture Office. To carry out the website competition, the Ministry of Agriculture has appointed a five person jury. To evaluate whether there are significant differences between the judges in scoring on the website which was considered and the factors that may affect the assessment, some analysis has been done. The variables included in the analysis was judge scores, level of institution, previous achievements in the competition, the location of both institutions in Java and outside Java. The statistical methods used in the analysis are Multiple Linear Regression and Variance Analysis. The analysis uses data from the Ministry of Agriculture Web Site Competition 2008-2010.

    Protein-peptide interactions play a key role in cell functions. Their structural characterization, though challenging, is important for the discovery of new drugs. The CABS-dock web server provides an interface for modeling protein-peptide interactions using a highly efficient protocol for the flexible docking of peptides to proteins. While other docking algorithms require pre-defined localization of the binding site, CABS-dock does not require such knowledge. Given a protein receptor structure and a peptide sequence (and starting from random conformations and positions of the peptide), CABS-dock performs simulation search for the binding site allowing for full flexibility of the peptide and small fluctuations of the receptor backbone. This protocol was extensively tested over the largest dataset of non-redundant protein-peptide interactions available to date (including bound and unbound docking cases). For over 80% of bound and unbound dataset cases, we obtained models with high or medium accuracy (sufficient for practical applications). Additionally, as optional features, CABS-dock can exclude user-selected binding modes from docking search or to increase the level of flexibility for chosen receptor fragments.

Although there are numerous Romanian initiatives of connecting to the Internet even smaller communities, like small towns or even communes, we have chosen the municipalities due to the positive relation between the number of inhabitants and the capacity to e-Government of the local public administration. All of the 103 Romanian municipalities have been analysed and the results obtained will be presented on each class (there are 5 different classes – e-doc, transparency, etc., but also by the final results.

    A web-based system for asynchronous multimedia messaging between shoulder replacement surgery patients at home and their surgeons was developed and tested. A web browser plug-in simplifies the process of capturing video and transferring it to a web site for novice computer users. The design of the video capture plug-in can be reused to acquire and securely transfer any type of data over the web. For example, readings from home biosensor instruments (e.g., glucometers and spirometers) that can be connected to a personal computer can be transferred to a home telemedicine web site. Both patients and doctors can access this web site to monitor health status longitudinally. Six patients, whose familiarity with computers ranged from no experience to expert users, used the system. All of the subjects were able to use the system to check treatment reminders and to send at least one message with video to their surgeons. The surgeons monitored the system regularly and always responded to messages within 24 h during the six-month trial period.

    Studies of the use of the World Wide Web to obtain medical knowledge have largely focused on patients. In particular, neither the international use of academic nephrology World Wide Web sites (websites) as primary information sources nor the use of search engines (and search strategies) to obtain medical information have been described. Visits ("hits") to the Walter Reed Army Medical Center (WRAMC) Nephrology Service website from April 30, 2000, to March 14, 2001, were analyzed for the location of originating source using Webtrends, and search engines (Google, Lycos, etc.) were analyzed manually for search strategies used. From April 30, 2000 to March 14, 2001, the WRAMC Nephrology Service website received 1,007,103 hits and 12,175 visits. These visits were from 33 different countries, and the most frequent regions were Western Europe, Asia, Australia, the Middle East, Pacific Islands, and South America. The most frequent organization using the site was the military Internet system, followed by America Online and automated search programs of online search engines, most commonly Google. The online lecture series was the most frequently visited section of the website. Search strategies used in search engines were extremely technical. The use of "robots" by standard Internet search engines to locate websites, which may be blocked by mandatory registration, has allowed users worldwide to access the WRAMC Nephrology Service website to answer very technical questions. This suggests that it is being used as an alternative to other primary sources of medical information and that the use of mandatory registration may hinder users from finding valuable sites. With current Internet technology, even a single service can become a worldwide information resource without sacrificing its primary customers.

    In randomized controlled trials, participants cannot choose their preferred intervention delivery mode and thus might refuse to participate or not engage fully if assigned to a nonpreferred group. This might underestimate the true effectiveness of behavior-change interventions. To examine whether receiving interventions either matched or mismatched with participants' preferred delivery mode would influence effectiveness of a Web-based physical activity intervention. Adults (n = 863), recruited via email, were randomly assigned to one of three intervention delivery modes (text based, video based, or combined) and received fully automated, Internet-delivered personal advice about physical activity. Personalized intervention content, based on the theory of planned behavior and stages of change concept, was identical across groups. Online, self-assessed questionnaires measuring physical activity were completed at baseline, 1 week, and 1 month. Physical activity advice acceptability and website usability were assessed at 1 week. Before randomization, participants were asked which delivery mode they preferred, to categorize them as matched or mismatched. Time spent on the website was measured throughout the intervention. We applied intention-to-treat, repeated-measures analyses of covariance to assess group differences. Attrition was high (575/863, 66.6%), though equal between groups (t(86) (3) =1.31, P =.19). At 1-month follow-up, 93 participants were categorized as matched and 195 as mismatched. They preferred text mode (493/803, 61.4%) over combined (216/803, 26.9%) and video modes (94/803, 11.7%). After the intervention, 20% (26/132) of matched-group participants and 34% (96/282) in the mismatched group changed their delivery mode preference. Time effects were significant for all physical activity outcomes (total physical activity: F(2,801) = 5.07, P = .009; number of activity sessions: F(2,801) = 7.52, P < .001; walking: F(2,801) = 8.32, P < .001; moderate physical

    The FLUXNET global network of regional flux tower networks serves to coordinate the regional and global analysis of eddy covariance based CO2, water vapor and energy flux measurements taken at more than 500 sites in continuous long-term operation. The FLUXNET database presently contains information about the location, characteristics, and data availability of each of these sites. To facilitate the coordination and distribution of this information, we redesigned the underlying database and associated web site. We chose the PostgreSQL database as a platform based on its performance, stability and GIS extensions. PostreSQL allows us to enhance our search and presentation capabilities, which will in turn provide increased functionality for users seeking to understand the FLUXNET data. The redesigned database will also significantly decrease the burden of managing such highly varied data. The website is being developed using the Drupal content management system, which provides many community-developed modules and a robust framework for custom feature development. In parallel, we are working with the regional networks to ensure that the information in the FLUXNET database is identical to that in the regional networks. Going forward, we also plan to develop an automated way to synchronize information with the regional networks.

    There is currently no validated method for assessing hospital disaster preparedness. We determine the degree of correlation between the results of 3 methods for assessing hospital disaster preparedness: administration of an on-site survey, drill observation using a structured evaluation tool, and video analysis of team performance in the hospital incident command center. This was a prospective, observational study conducted during a regional disaster drill, comparing the results from an on-site survey, a structured disaster drill evaluation tool, and a video analysis of teamwork, performed at 6 911-receiving hospitals in Los Angeles County, CA. The on-site survey was conducted separately from the drill and assessed hospital disaster plan structure, vendor agreements, modes of communication, medical and surgical supplies, involvement of law enforcement, mutual aid agreements with other facilities, drills and training, surge capacity, decontamination capability, and pharmaceutical stockpiles. The drill evaluation tool, developed by Johns Hopkins University under contract from the Agency for Healthcare Research and Quality, was used to assess various aspects of drill performance, such as the availability of the hospital disaster plan, the geographic configuration of the incident command center, whether drill participants were identifiable, whether the noise level interfered with effective communication, and how often key information (eg, number of available staffed floor, intensive care, and isolation beds; number of arriving victims; expected triage level of victims; number of potential discharges) was received by the incident command center. Teamwork behaviors in the incident command center were quantitatively assessed, using the MedTeams analysis of the video recordings obtained during the disaster drill. Spearman rank correlations of the results between pair-wise groupings of the 3 assessment methods were calculated. The 3 evaluation methods demonstrated

    2006-01-01

    Expanded newborn screening programs and subsequent detection of rare genetic disorders challenge parents and their medical providers to learn about the treatment and management of these disorders. Many people seek medical information on the Internet but may encounter requests for registration or fees, or find that resources are out of date, difficult to understand, or buried in advertisements. The U.S. National Library of Medicine (NLM), a component of the National Institutes of Health, provides web-based resources that address the challenges of newborn screening education. These resources include MedlinePlus, Genetics Home Reference, ClinicalTrials.gov, and PubMed. NLM websites are not commercial, do not require registration or fees, and provide varied levels of information for a continuum of audiences from low-literacy consumers to health professionals. Using phenylketonuria as an example, this study describes the information that parents and their medical providers can find through NLM resources. NLM has embraced the digital age and provides the public with reliable, accurate, and up-to-date educational materials. Copyright (c) 2006 Wiley-Liss, Inc.

    The widespread use of the World Wide Web by persons from different age groups, diverse cultures, and with different computer skills has put more emphasis in the process of ensuring that web sites and applications are usable. On the other hand we can see how plain text web pages have been replaced by ones in which multimedia information (images, video and audio) are an important part of them. In this context we have developed a multi-agent system for analysing web usability that performs both static and dynamic analysis of web sites. The static analysis can examine certain multimedia issues related to usability (mostly associated with images) and in this paper we also comment on the issues related with video and audio technologies.

    Response of dandelion (Taraxacum officinale Web) to heavy metals from mine sites: micromorphology of leaves and roots. Maleci L.1 , Bini C.2, Buffa G. 2, Fontana S2., Wahsha M.3 1 - Dept of Biology, University of Florence, Italy. 2 - Dept of Environmental Sciences, Informatics and Statistics. Ca'Foscari University, Venice - Italy. 3 - Marine Science Centre - University of Jordan, Aqaba section, Jordan. Heavy metal accumulation is known to produce significant physiological and biochemical responses in vascular plants. Yet, metabolic and physiological responses of plants to heavy metal concentration can be viewed as potentially adaptive changes of the plants during stress. From this point of view, plants growing on abandoned mine sites are of particular interest, since they are genetically tolerant to high metal concentrations, and can be utilized in soil restoration. Among wild plants, the common dandelion (Taraxacum officinale Web) has received attention as bioindicator plant, and has been also suggested in remediation projects. Wild specimens of Taraxacum officinale Web, with their soil clod, were gathered from three sites with different contamination levels by heavy metals (Cd, Cr, Cu, Fe, Pb, Zn) in the abandoned Imperina Valley mine (Northeast Italy). A control plant was also gathered from a not contaminated site nearby. Plants were cultivated in pots for one year at HBF, and appeared macroscopically not affected by toxic signals (reduced growth, leaf necrosis) possibly induced by soil HM concentration. Leaves and roots taken at the same growing season were observed by LM and TEM. Light microscopy observations carried out on the leaf lamina show a clear difference in the cellular organization of not-contaminated and contaminated samples. The unpolluted samples present a well organized palisade tissue and spongy photosynthetic parenchyma. Samples from contaminated sites, instead, present a palisade parenchyma less organized, and a reduction of leaf thickness

    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 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.

    Traditionally, telemedicine systems have been designed to improve access to care by allowing physicians to consult a specialist about a case without sending the patient to another location, which may be difficult or time-consuming to reach. The cost of the equipment and network bandwidth needed for this consultation has restricted telemedicine use to contact between physicians instead of between patients and physicians. Recently, however, the wide availability of Internet connectivity and client and server software for e- mail, world wide web, and conferencing has made low-cost telemedicine applications feasible. In this work, we present a web-based system for asynchronous multimedia messaging between shoulder replacement surgery patients at home and their surgeons. A web browser plug-in was developed to simplify the process of capturing video and transferring it to a web site. The video capture plug-in can be used as a template to construct a plug-in that captures and transfers any type of data to a web server. For example, readings from home biosensor instruments (e.g., blood glucose meters and spirometers) that can be connected to a computing platform can be transferred to a home telemedicine web site. Both patients and doctors can access this web site to monitor progress longitudinally. The system has been tested with 3 subjects for the past 7 weeks, and we plan to continue testing in the foreseeable future.

    Recruitment of young people for health research by traditional methods has become more expensive and challenging over recent decades. The Internet presents an opportunity for innovative recruitment modalities. To assess the feasibility of recruiting young females using targeted advertising on the social networking site Facebook. We placed an advertisement on Facebook from May to September 2010, inviting 16- to 25-year-old females from Victoria, Australia, to participate in a health study. Those who clicked on the advertisement were redirected to the study website and were able to express interest by submitting their contact details online. They were contacted by a researcher who assessed eligibility and invited them to complete a health-related survey, which they could do confidentially and securely either at the study site or remotely online. A total of 551 females responded to the advertisement, of whom 426 agreed to participate, with 278 completing the survey (139 at the study site and 139 remotely). Respondents' age distribution was representative of the target population, while 18- to 25-year-olds were more likely to be enrolled in the study and complete the survey than 16- to 17-year-olds (prevalence ratio=1.37, 95% confidence interval 1.05-1.78, P=.02). The broad geographic distribution (major city, inner regional, and outer regional/remote) and socioeconomic profile of participants matched the target population. Predictors of participation were older age, higher education level, and higher body mass index. Average cost in advertising fees per compliant participant was US $20, making this highly cost effective. Results demonstrate the potential of using modern information and communication technologies to engage young women in health research and penetrate into nonurban communities. The success of this method has implications for future medical and population research in this and other demographics.

    Oral and pharyngeal cancers are responsible for over 7600 deaths each year in the United States. Given the significance of the disease and the fact that many individuals increasingly rely on health information on the Internet, it is important that patients and others can access clear and accurate oral cancer information on the Web. The objective of this study was threefold: (a) develop an initial method to evaluate surface and content quality of selected English- and Spanish-language oral cancer Web sites; (b) conduct a pilot evaluation; and (c) discuss implications of our findings for dental public health. We developed a search strategy to find oral cancer sites frequented by the public using Medline Plus, Google, and Yahoo in English and Spanish. We adapted the Information Quality Tool (IQT) to perform a surface evaluation and developed a novel tool to evaluate site content for 24 sites each in English and Spanish. English-language sites had an average IQT score of 76.6 (out of 100) and an average content score of 52.1 (out of 100). Spanish-language sites had an average IQT score of 50.3 and an average content score of 25.6. The study produced a quality assessment of oral cancer Web sites useful for clinicians and patients. Sites provided more information on clinical presentation, and etiology, and risk factors, than other aspects of oral cancer. The surface and quality of Spanish-language sites was low, possibly putting Hispanic populations at a disadvantage regarding oral cancer information on the Web.

    N6-Methyladenosine (m6A) is the most prevalent and abundant modification in mRNA that has been linked to many key biological processes. High-throughput experiments have generated m6A-peaks across the transcriptome of A. thaliana, but the specific methylated sites were not assigned, which impedes the understanding of m6A functions in plants. Therefore, computational prediction of mRNA m6A sites becomes emergently important. Here, we present a method to predict the m6A sites for A. thaliana mRNA sequence(s). To predict the m6A sites of an mRNA sequence, we employed the support vector machine to build a classifier using the features of the positional flanking nucleotide sequence and position-independent k-mer nucleotide spectrum. Our method achieved good performance and was applied to a web server to provide service for the prediction of A. thaliana m6A sites. The server also provides a comprehensive database of predicted transcriptome-wide m6A sites and curated m6A-seq peaks from the literature for query and visualization. The AthMethPre web server is the first web server that provides a user-friendly tool for the prediction and query of A. thaliana mRNA m6A sites, which is freely accessible for public use at .

    2012-04-01

    In this follow-up study, we aimed to assess national and international pharmaceutical companies' Web sites using guidelines of The Association of Research-Based Pharmaceutical Companies (AIFD) and Pharmaceutical Manufacturers Association of Turkey (IEIS) to define whether there has been progress since 2004. We used two national guidelines in order to evaluate the Web sites of pharmaceutical companies in our study. The first guideline was from IEIS, and the second was from AIFD, which was issued recently. We collected our data between February 1 and April 30, 2011. Data analyses were performed using SPSS version 15.0. Chi squared test was done for comparing the two assessments in different years (2004 and 2011). In general, the progress that we were expecting was not satisfactory for both the international and national companies. The percentage of unmet criteria increased for "links" (from 48.0% to 52.0%) and for "mentioning the responsible person/firm for the Web site design" (from 40.6% to 59.4%) among national companies. We observed statistically significant progress only for the "information for the public" criterion (from 52.9% to 100%) among international companies. On the other hand, there was progress and a statistically significant difference in terms of not displaying any "drug ads" on the Web sites of national firms (from 55.9% to 87.5%), availability of "mail address" (from 88.2% to 100%), "telephone number" (from 88.2% to 100%), "indication of the target group" (from 23.5% to 52.1%), and "disclaimer stating the given information cannot replace a physician or pharmacist" (from 29.4% to 53.1%). Our major recommendation to pharmaceutical companies is to update their Web sites with evidence-based scientific information about themselves and their products using international and national standards. From the companies' perspective, this should be a priority responsibility based on the ethical aspect of individual and community health.

  3. QOI6/416: The Health On the Net Code of Conduct for Medical and Health-related Web sites: Three years on

    Boyer, C; Baujard, V; Nater, T; Scherrer, JR; Appel, RD

    1999-01-01

    Introduction The explosive growth of the World Wide Web has made it more and more urgent to monitor and improve the quality of the information circulating through the Internet. But assessing medical and health information on the Web is a difficult challenge. In recent years, some organisations have been working on this issue. The Health On the Net Foundation (HON), for its part, administers an eight-point Code of Conduct called the HONcode, initiated in 1996. This solution is different from the others. The HONcode does not intend to rate or assess the quality of information provided by a Web site. This article gives a general presentation of the HONcode and its status in 1999, three years after it was launched. Methods It defines a set of voluntary rules designed to help a Web developer site practice responsible and to make sure a reader always knows the source and the purpose of the information he or she is reading. These guidelines encourage the authority, complimentarity, confidentiality, proper attribution, justifiability and validity of the medical advice and information provided. Furthermore, sites that subscribe to the HONcode commit themselves to providing transparent information on site sponsorship and clearly separating advertising and editorial content. Results In 1998, the number of external links to the HONcode principles page grew by about 250% (e.g., from 2 to 5) . The rate of increase from January through April, 1999, suggests 300% this year. The growth in the number of links to the HONcode matches that of links to of the entire Web site, and is slightly higher than growth in links to HON's MedHunt search engine. Statistical analysis shows that approximately 50% of Web sites linked to the HONcode principles have a commercial domain name, 16% are from European countries, 15% are from non-profit organisations, and 7% are educational sites. Discussion This evolution shows a real need of guidelines for the developers of medical and health Web sites and

    Full Text Available The ever-increasing evolution of the Internet and the growing number of the resources accessible through this medium, has turned the issue of resource evaluation of the internet-based information into a controversial and cogent issue. By nature, the internet milieu is uncontrollable. It concomitantly contains both verifiable and unverifiable information. Thus it behooves the internet users to develop resource evaluation and critical thinking skills in order to discern appropriate quality resources. Through review and comparison of the available checklists, the present paper endeavors to offer criteria for website evaluation

    Despite the use of web-based information resources by both anesthesia departments and applicants, little research has been done to assess these resources and determine whether they are meeting applicant needs. Evidence is needed to guide anesthesia informatics research in developing high-quality anesthesia residency program Web sites (ARPWs). We used an anonymous web-based program (SurveyMonkey, Portland, OR) to distribute a survey investigating the information needs and perceived usefulness of ARPWs to all 572 Stanford anesthesia residency program applicants. A quantitative scoring system was then created to assess the quality of ARPWs in meeting the information needs of these applicants. Two researchers independently analyzed all 131 ARPWs in the United States to determine whether the ARPWs met the needs of applicants based on the scoring system. Finally, a qualitative assessment of the overall user experience of ARPWs was developed to account for the subjective elements of the Web site's presentation. Ninety-eight percent of respondents reported having used ARPWs during the application process. Fifty-six percent reported first visiting the Stanford ARPW when deciding whether to apply to Stanford's anesthesia residency program. Multimedia and Web 2.0 technologies were "very" or "most" useful in "learning intangible aspects of a program, like how happy people are" (42% multimedia and Web 2.0 versus 14% text and photos). ARPWs, on average, contained only 46% of the content items identified as important by applicants. The average (SD) quality scores among all ARPWs was 2.06 (0.59) of 4.0 maximum points. The mean overall qualitative score for all 131 ARPWs was 4.97 (1.92) of 10 points. Only 2% of applicants indicated that the majority (75%-100%) of Web sites they visited provided a complete experience. Anesthesia residency applicants rely heavily on ARPWs to research programs, prepare for interviews, and formulate a rank list. Anesthesia departments can improve their

  8. Video Pulses: User-Based Modeling of Interesting Video Segments

    Directory of Open Access Journals (Sweden)

    Markos Avlonitis

    2014-01-01

    Full Text Available We present a user-based method that detects regions of interest within a video in order to provide video skims and video summaries. Previous research in video retrieval has focused on content-based techniques, such as pattern recognition algorithms that attempt to understand the low-level features of a video. We are proposing a pulse modeling method, which makes sense of a web video by analyzing users' Replay interactions with the video player. In particular, we have modeled the user information seeking behavior as a time series and the semantic regions as a discrete pulse of fixed width. Then, we have calculated the correlation coefficient between the dynamically detected pulses at the local maximums of the user activity signal and the pulse of reference. We have found that users' Replay activity significantly matches the important segments in information-rich and visually complex videos, such as lecture, how-to, and documentary. The proposed signal processing of user activity is complementary to previous work in content-based video retrieval and provides an additional user-based dimension for modeling the semantics of a social video on the web.

    2013-10-01

    Knee arthrocentesis is a commonly performed diagnostic and therapeutic procedure in rheumatology and orthopedic surgery. Classic teaching of arthrocentesis skills relies on hands-on practice under supervision. Video-based online teaching is an increasingly utilized educational tool in higher and clinical education. YouTube is a popular video-sharing Web site that can be accessed as a teaching source. The objective of this study was to assess the educational value of YouTube videos on knee arthrocentesis posted by health professionals and institutions during the period from 2008 to 2012. The YouTube video database was systematically searched using 5 search terms related to knee arthrocentesis. Two independent clinical reviewers assessed videos for procedural technique and educational value using a 5-point global score, ranging from 1 = poor quality to 5 = excellent educational quality. As validated international guidelines are lacking, we used the guidelines of the Swiss Society of Rheumatology as criterion standard for the procedure. Of more than thousand findings, 13 videos met the inclusion criteria. Of those, 2 contained additional animated video material: one was purely animated, and one was a check list. The average length was 3.31 ± 2.28 minutes. The most popular video had 1388 hits per month. Our mean global score for educational value was 3.1 ± 1.0. Eight videos (62 %) were considered useful for teaching purposes. Use of a "no-touch" procedure, meaning that once disinfected the skin remains untouched before needle penetration, was present in all videos. Six videos (46%) demonstrated full sterile conditions. There was no clear preference of a medial (n = 8) versus lateral (n = 5) approach. A discreet number of YouTube videos on knee arthrocentesis appeared to be suitable for application in a Web-based format for medical students, fellows, and residents. The low-average mean global score for overall educational value suggests an improvement of future video

    To assess the frequency of impaired awareness of hypoglycaemia (IAH) using a specific questionnaire (Spanish version) in a free access diabetes-related web site. Data from a free access Spanish version of the Clarke test previously uploaded to the website of the Fundación para la Diabetes (March 2014-January 2015) were assessed. In addition to the eight questions in Clarke's questionnaire, information on type of diabetes, age, and disease duration was obtained. The Clarke test divided participants into three categories: normal awareness, uncertain and IAH. Of the 418 participants with type 1 diabetes, 51.2% were aged 36-55 years. In 34.7%, diabetes had been diagnosed >15 years before, while disease duration was 2 years in 11%. According to Clarke categories, 23.4% had IAH, 15.3% uncertain awareness, and 61.3% normal awareness. The longer the duration of diabetes, the higher the Clarke test score. According to the Clarke test, 14.1% of participants had experienced at least one episode of severe hypoglycaemia in the previous year, and half of these (7.4%) had suffered severe hypoglycaemia two or more times. All but one of the participants with two or more episodes of severe hypoglycaemia had IAH. Our study shows that the rate of IAH using an online survey is similar (25%) to that previously reported in other geographical areas, increases with diabetes duration, and identifies subjects prone to severe hypoglycaemia.

    While experts recommend that the readability of patient education materials should be less than the sixth grade level, the available information pertaining to orthopaedic diseases may be excessively complex for some to read and comprehend. The Flesch-Kincaid grade level is the most widely used tool to evaluate the readability score of a given text, with a lower grade level suggesting easier readability. The goal of our study was to assess the readability of pediatric orthopaedic patient education materials that were developed by the American Academy of Orthopaedic Surgeons (AAOS) and the Pediatric Orthopaedic Society of North America (POSNA) and were accessible to the general public through the Internet. All articles from the "Children" section of the patient education library, "Your Orthopaedic Connection," on the AAOS web site and the "Parent/Patient" section on the POSNA web site were identified. The Flesch-Kincaid grade level of each article was determined with use of Microsoft Office Word software. The mean grade levels of articles that were available in 2001 were compared with those accessible in 2007. Fifty-seven unique articles were available in 2007 on both web sites compared with twenty-five articles available in 2001. The readability score of only one (2%) of the currently available articles was less than sixth grade level. The mean Flesch-Kincaid grade level of the currently available articles was 8.9 compared with 8.7 for the articles available in 2001 (p = 0.71). Our findings suggest that most of the pediatric orthopaedic patient education materials available on the AAOS and POSNA web sites have readability scores that may be too high, making comprehension difficult for a substantial portion of the United States population.

    Objective: In this study, the reliability of Turkish cardiac massage and Basic Life Support (BLS) videos, which have already been downloaded from three website such as YouTube, Google, Yahoo following the publication of 2010 cardiopulmonary resuscitation (CPR) guideline and their suitability to the same guideline were researched. Materials and Methods: The videos uploaded to the three web-site to search videos on internet were queried by using the keywords “cardiac massage” and “basic life support”. Videos that had been uploaded between January 2011 and July 2014 were analyzed and scored by two experienced emergency specialists. Results: A total of 1126 videos were obtained. 1029 of the videos (91.4%) were excluded by researchers. 97 videos were detected to accord with study criteria. Despite most of the videos were found on Google website by keywords, the enormous part of videos proper to criteria were sourced from YouTube website (n=65, 67.0%). One fourth of the videos (24.7%) were observed to not be suitable for 2010 CPR guideline. AED usage was mentioned slightly in the videos (14.4%). Median score of the videos is 5 (IQR: 4–6). The rate and scores of the videos uploaded by official institution or association were significantly higher than others (p=0.007 and 0.006, respectively). Moreover, scores of the videos compatible with guidelines uploaded by official institution or association and medical personal were also found higher (p=0.001). Conclusion: Eventually, all the data obtained in this study support that Turkish videos were not reliable on the subject of BLS and cardiac massage. It is promising that videos with high follow-up rates also have been scored higher. PMID:27026758

    2017-09-05

    The growing number of bariatric surgery videos shared on YouTube highlights the need for content and quality assessment. The aim of this study was to answer the question 'Is watching these videos useful to surgeons and patients?' YouTube was searched using the keywords 'obesity surgery', 'bariatric surgery' and 'weight loss surgery', and 100 videos retrieved using each keyword were classified based on their 'usefulness score' as very useful, useful and not useful. Video content; source; length and number of views, likes and dislikes were recorded. Upload sources included doctors or hospitals (DH), medical web sites or TV channels (MW), commercial web sites (CW) or civilians (CI). Between-group differences were compared. Of the 300 videos watched, 175 were included in the study; 53.7% were useful and 24.6% were very useful. There were no between-group differences in the number of likes (p = 0.480), dislikes (p = 0.592) and views (p = 0.104). Most videos were uploaded by MW and DH, also with no significant differences in the number of likes (p = 0.35), dislikes (p = 0.14) and views (p = 0.93). No videos were found with misleading information. The popularity of bariatric surgery and interest of both patients and surgeons are increasing daily. Although videos on bariatric surgery on YouTube may be more useful than those on other surgical procedures, it is important that the videos are uploaded by medical professionals and that specific upload and retrieval filters are applied.

    This research volume presents a sample of recent contributions related to the issue of quality-assessment for Web Based information in the context of information access, retrieval, and filtering systems. The advent of the Web and the uncontrolled process of documents' generation have raised the problem of declining quality assessment to information on the Web, by considering both the nature of documents (texts, images, video, sounds, and so on), the genre of documents ( news, geographic information, ontologies, medical records, products records, and so on), the reputation of information sources and sites, and, last but not least the actions performed on documents (content indexing, retrieval and ranking, collaborative filtering, and so on). The volume constitutes a compendium of both heterogeneous approaches and sample applications focusing specific aspects of the quality assessment for Web-based information for researchers, PhD students and practitioners carrying out their research activity in the field of W...

    This article describes the development, use, and student response to an online manual developed with off-the-shelf software and made available using a web-based course management system (Blackboard) that was used to transform a freshman restorative preclinical technique course from a lecture-only course into an interactive web-enhanced course. The goals of the project were to develop and implement a web-enhanced interactive learning experience in a preclinical restorative technique course and shift preclinical education from a teacher-centered experience to a student-driven experience. The project was evaluated using an anonymous post-course survey (95 percent response rate) of 123 freshman students that assessed enabling (technical support and access to the technology), process (the actual experience and usability), and outcome criteria (acquisition and successful use of the knowledge gained and skills learned) of the online manual. Students responded favorably to sections called "slide galleries" where ideal and non-ideal examples of projects could be viewed. Causes, solutions, and preventive measures were provided for the errors shown. Sections called "slide series" provided cookbook directions allowing for self-paced and student-directed learning. Virtually all of the students, 99 percent, found the quality of the streaming videos adequate to excellent. Regarding Internet connections and video viewing, 65 percent of students successfully viewed the videos from a remote site; cable connections were the most reliable, dial-up connections were inadequate, and DSL connections were variable. Seventy-three percent of the students felt the videos were an effective substitute for in-class demonstrations. Students preferred video with sound over video with subtitles and preferred short video clips embedded in the text over compilation videos. The results showed it is possible to develop and implement web-enhanced and interactive dental education in a preclinical

    Full Text Available Son yıllarda internet kullanımı birçok sektörde olduğu gibi turizm sektöründe de online seyahat alımlarını ön plana çıkarmış ve otellerin web siteleri önemli bir iletişim ve pazarlama medya aracı durumuna gelmiştir. Bu bağlamda, gerekli donanıma ve zenginliğe sahip Türkiye’deki otellerin bu aracı gerçekte nasıl kullanmaları gerektiği ve şu anda nasıl kullandıkları önemli bir konu olarak karşımıza çıkmaktadır. Yapılan yazın taraması sonucunda otellerin web sitelerinin taşıması gereken içerik ve tasarım özelliklerini ortaya koyan bir model geliştirilmiştir. Bu modele dayanılarak, Türkiye turizminin pazarda kültür turizmine katkısı olacağı düşünülen “Dünya Miras Listesi”nde yer alan bölgelerdeki üç, dört ve beş yıldızlı toplam 335 otelin web sitesi analiz edilmiştir. Elde edilen sonuçlardan hareketle, otel web sitelerinde adres, telefon numarası, e-posta adresi ve otel resimlerinin dışında potansiyel turistin dikkatini, otelin bulunduğu yöreye çekebileceği düşünülen çevre, turizm potansiyeli, yöreye ilişkin bilgi vb. gibi birçok konuda hiçbir bilginin olmadığı gözlenmiştir. Ayrıca çalışmada, konuyla ilgili olarak etkin bir web sitesi hazırlamaya yönelik olarak bazı öneriler sunulmuştur.-Increased use of Internet in the recent years caused a boom in online purchasing of travel services and made web sites of hotels important marketing and communication tools for the tourism industry.

    The process of digital capture, editing, and archiving video has become an important aspect of documenting arthroscopic surgery. Recording the arthroscopic findings before and after surgery is an essential part of the patient's medical record. The hardware and software has become more reasonable to purchase, but the learning curve to master the software is steep. Digital video is captured at the time of arthroscopy to a hard disk, and written to a CD at the end of the operative procedure. The process of obtaining video of open procedures is more complex. Outside video of the procedure is recorded on digital tape with a digital video camera. The camera must be plugged into a computer to capture the video on the hard disk. Adobe Premiere software is used to edit the video and render the finished video to the hard drive. This finished video is burned onto a CD. We outline the choice of computer hardware and software for the manipulation of digital video. The techniques of backup and archiving the completed projects and files also are outlined. The uses of digital video for education and the formats that can be used in PowerPoint presentations are discussed.
