    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.

    The unique characteristic of web applications is that they are supposed to be used by much bigger and diverse set of users and stakeholders. An example application area is e-Learning or business to business interaction. In eLearning environment, various users with different background use the eLearning......-based applications aim to leave some of their features at the design stage in the form of variables which are dependent on several criteria. The resolution of the variables is called adaptation and can be seen from two perspectives: adaptation by humans to the changed requirements of stakeholders and dynamic system...... adaptation to the changed parameters of environments, user or context. Adaptation can be seen as an orthogonal concern or viewpoint in a design process. In this paper I will discuss design abstractions which are employed in current design methods for web applications. I will exemplify the use...

    Abdul, Hameed

    2016-01-01

    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.

  13. Adaptive web data extraction policies

    Directory of Open Access Journals (Sweden)

    Provetti, Alessandro

    2008-12-01

    Full Text Available Web data extraction is concerned, among other things, with routine data accessing and downloading from continuously-updated dynamic Web pages. There is a relevant trade-off between the rate at which the external Web sites are accessed and the computational burden on the accessing client. We address the problem by proposing a predictive model, typical of the Operating Systems literature, of the rate-of-update of each Web source. The presented model has been implemented into a new version of the Dynamo project: a middleware that assists in generating informative RSS feeds out of traditional HTML Web sites. To be effective, i.e., make RSS feeds be timely and informative and to be scalable, Dynamo needs a careful tuning and customization of its polling policies, which are described in detail.

  14. From Web accessibility to Web adaptability.

    Science.gov (United States)

    Kelly, Brian; Nevile, Liddy; Sloan, David; Fanou, Sotiris; Ellison, Ruth; Herrod, Lisa

    2009-07-01

    This article asserts that current approaches to enhance the accessibility of Web resources fail to provide a solid foundation for the development of a robust and future-proofed framework. In particular, they fail to take advantage of new technologies and technological practices. The article introduces a framework for Web adaptability, which encourages the development of Web-based services that can be resilient to the diversity of uses of such services, the target audience, available resources, technical innovations, organisational policies and relevant definitions of 'accessibility'. The article refers to a series of author-focussed approaches to accessibility through which the authors and others have struggled to find ways to promote accessibility for people with disabilities. These approaches depend upon the resource author's determination of the anticipated users' needs and their provision. Through approaches labelled as 1.0, 2.0 and 3.0, the authors have widened their focus to account for contexts and individual differences in target audiences. Now, the authors want to recognise the role of users in determining their engagement with resources (including services). To distinguish this new approach, the term 'adaptability' has been used to replace 'accessibility'; new definitions of accessibility have been adopted, and the authors have reviewed their previous work to clarify how it is relevant to the new approach. Accessibility 1.0 is here characterised as a technical approach in which authors are told how to construct resources for a broadly defined audience. This is known as universal design. Accessibility 2.0 was introduced to point to the need to account for the context in which resources would be used, to help overcome inadequacies identified in the purely technical approach. Accessibility 3.0 moved the focus on users from a homogenised universal definition to recognition of the idiosyncratic needs and preferences of individuals and to cater for them. All of

    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.

    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...

    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.

    Full Text Available This paper describes our proposition for adaptive web services which is based on configurable, re-usable adaptive/personalized services. To realize our ideas, we have developed an approach for designing, implementing and maintaining personal service. This approach enables the user to accomplish an activity with a set of services answering to his preferences, his profiles and to a personalized context. In this paper, we describe the principle of our approach that we call fractal adaptation approach, and we discuss the implementation of personalization services in the context of mobile and collaborative scenario of learning. We have realized a platform in this context -a platform for mobile and collaborative learning- based on fractal adaptable web services. The platform is tested with a population of students and tutors, in order to release the gaps and the advantages of the approach suggested.

    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.

  3. Usability Evaluation of Public Web Mapping Sites

    Science.gov (United States)

    Wang, C.

    2014-04-01

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

    The use of the Internet has a ten-year history in Hungary. In the beginning, users were surfing on textual Web sites with the browser Lynx (1991), then a range of graphic browsers appeared: Mosaic (1993) , Netscape (1994), and finally Internet Explorer (1995). More and more institutions, including libraries decided to enter the World Wide Web with their own homepage. The past ten years have brought enormous changes and new requirements in the way that institutional homepages are designed. This article offers an overview of the development phases of Web sites, presents the new tools necessary for the state-of-the-art design and gives advice on their up-to-date maintenance.

    Ghali, Fawaz; Cristea, Alexandra I.

    In this paper, we describe the design steps of extending LAOS, a five-layer framework for generic adaptive web learning authoring, by adding a social layer to capture (and adapt) information from 1) collaborative authoring (i.e. editing the content of other learners, describing the content using tags, rating the content, and commenting on the content, etc); and 2) authoring for collaboration (i.e., adding authors’ activities, such as defining groups of authors, subscribing to other authors, etc). Moreover, the paper presents MOT 2.0, an adaptive E-learning 2.0 system, which is built on the proposed reference model, and finally, we report on our evaluations to validate the new Social Layer by comparing MOT 2.0 with its predecessor, MOT 1.0.

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

    To 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.

  19. Physician-Rating Web Sites: Ethical Implications.

    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.

  8. 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

    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.

    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.

    Price, John; Spreng, Carl; Hawley, Elisabeth L; Deeb, Rula

    2017-12-15

    Complex sites require a disproportionate amount of resources for environmental remediation and long timeframes to achieve remediation objectives, due to their complex geologic conditions, hydrogeologic conditions, geochemical conditions, contaminant-related conditions, large scale of contamination, and/or non-technical challenges. A recent team of state and federal environmental regulators, federal agency representatives, industry experts, community stakeholders, and academia worked together as an Interstate Technology & Regulatory Council (ITRC) team to compile resources and create new guidance on the remediation management of complex sites. This article summarizes the ITRC team's recommended process for addressing complex sites through an adaptive site management approach. The team provided guidance for site managers and other stakeholders to evaluate site complexities and determine site remediation potential, i.e., whether an adaptive site management approach is warranted. Adaptive site management was described as a comprehensive, flexible approach to iteratively evaluate and adjust the remedial strategy in response to remedy performance. Key aspects of adaptive site management were described, including tools for revising and updating the conceptual site model (CSM), the importance of setting interim objectives to define short-term milestones on the journey to achieving site objectives, establishing a performance model and metrics to evaluate progress towards meeting interim objectives, and comparing actual with predicted progress during scheduled periodic evaluations, and establishing decision criteria for when and how to adapt/modify/revise the remedial strategy in response to remedy performance. Key findings will be published in an ITRC Technical and Regulatory guidance document in 2017 and free training webinars will be conducted. More information is available at www.itrc-web.org.

    2008-01-01

    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.

  11. 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.

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

    Science.gov (United States)

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Hicks, D.

    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.

    Full Text Available Semantic Web Services (SWS are Web Service (WS descriptions augmented with semantic information. SWS enable intelligent reasoning and automation in areas such as service discovery, composition, mediation, ranking and invocation. This paper applies SWS to a previous protocol adapter which, operating within clearly defined constraints, maps SOAP Web Services to RESTful HTTP format. However, in the previous adapter, the configuration element is manual and the latency implications are locally based. This paper applies SWS technologies to automate the configuration element and the latency tests are conducted in a more realistic Internet based setting.

    2017-07-01

    To facilitate progress in climate change adaptation policy and practice, it is important not only to ensure the production of accurate, comprehensive and relevant information, but also the easy, timely and affordable access to it. This can contribute to better-informed decisions and improve the design and implementation of adaptation policies and other relevant initiatives. Web-based platforms can play an important role in communicating and distributing data, information and knowledge that become constantly available, reaching out to a large group of potential users. Indeed in the last decade there has been an extensive increase in the number of platforms developed for this purpose in many fields including climate change adaptation. This short paper concentrates on the web-based adaptation platforms developed in Europe. It provides an overview of the recently emerged landscape, examines the basic characteristics of a set of platforms that operate at national, transnational and European level, and discusses some of the key challenges related to their development, maintenance and overall management. Findings presented in this short paper are discussed in greater detailed in the Technical Report of the European Environment Agency Overview of climate change adaptation platforms in Europe.

    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.

  10. Prescription drug brand Web sites: Guidance where none exists

    Directory of Open Access Journals (Sweden)

    Lewis Glinert, Ph.D

    2010-01-01

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

    Full Text Available 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.

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

  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.

    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.

    A work is devoted to the application of an information-computational Web GIS "Climate" developed by joint team of the Institute of Monitoring of Climatic and Ecological Systems SB RAS and Tomsk State University to raise awareness about current and future climate change as a basis for further adaptation. Web-GIS "Climate» (http://climate.scert.ru/) based on modern concepts of Web 2.0 provides opportunities to study regional climate change and its consequences by providing access to climate and weather models, a large set of geophysical data and means of processing and visualization. Also, the system is used for the joint development of software applications by distributed research teams, research based on these applications and undergraduate and graduate students training. In addition, the system capabilities allow creating information resources to raise public awareness about climate change, its causes and consequences, which is a necessary step for the subsequent adaptation to these changes. Basic information course on climate change is placed in the public domain and is aimed at local population. Basic concepts and problems of modern climate change and its possible consequences are set out and illustrated in accessible language. Particular attention is paid to regional climate changes. In addition to the information part, the course also includes a selection of links to popular science network resources on current issues in Earth Sciences and a number of practical tasks to consolidate the material. These tasks are performed for a particular territory. Within the tasks users need to analyze the prepared within the "Climate" map layers and answer questions of direct interest to the public: "How did the minimum value of winter temperatures change in your area?", "What are the dynamics of maximum summer temperatures?", etc. Carrying out the analysis of the dynamics of climate change contributes to a better understanding of climate processes and further adaptation

  9. AIDS web sites face censorship under new rating schemes.

    Science.gov (United States)

    1997-08-22

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

  11. 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.

    Having a Web site is no longer a luxury or perk for your practice and your patients. A Web site is a basic necessity that patients are expecting firom their physicians and their practices. But patients want more than a mere Internet presence. They are expecting an interactive Web site, and they want to be able to communicate with the practice and the physicians. This article will discuss the creation of an interactive Web site and why it is necessary for doctors to enhance their Web site so that patients can interact with the practice.

  13. Context-Aware Adaptation in Web-Based Groupware Systems

    Science.gov (United States)

    Pinheiro, Manuele Kirsch; Carrillo-Ramos, Angela; Villanova-Oliver, Marlène; Gensel, Jérôme; Berbers, Yolande

    In this chapter, we propose a context-aware filtering process for adapting content delivered to mobile users by Web-based Groupware Systems. This process is based on context-aware profiles, expressing mobile users preferences for particular situations they encounter when using these systems. These profiles, which are shared between members of a given community, are exploited by the adaptation process in order to select and organize the delivered information into several levels of detail, based on a progressive access model. By defining these profiles, we propose a filtering process that considers both the user's current context and the user's preferences for this context. The context notion of context is represented by an object-oriented model we propose and which takes into account consideration both the user's physical and collaborative context, including elements related to collaborative activities performed inside the groupware system. The filtering process selects, in a first step, the context-aware profiles that match the user's current context, and then it filters the available content according to the selected profiles and uses the progressive access model to organize the selected information.

  14. Adaptive foraging does not always lead to more complex food webs.

    Science.gov (United States)

    Berec, Ludek; Eisner, Jan; Krivan, Vlastimil

    2010-09-21

    Recent modeling studies exploring the effect of consumers' adaptivity in diet composition on food web complexity invariably suggest that adaptivity in foraging decisions of consumers makes food webs more complex. That is, it allows for survival of a higher number of species when compared with non-adaptive food webs. Population-dynamical models in these studies share two features: parameters are chosen uniformly for all species, i.e. they are species-independent, and adaptive foraging is described by the search image model. In this article, we relax both these assumptions. Specifically, we allow parameters to vary among the species and consider the diet choice model as an alternative model of adaptive foraging. Our analysis leads to three important predictions. First, for species-independent parameter values for which the search image model demonstrates a significant effect of adaptive foraging on food web complexity, the diet choice model produces no such effect. Second, the effect of adaptive foraging through the search image model attenuates when parameter values cease to be species-independent. Finally, for the diet choice model we observe no (significant) effect of adaptive foraging on food web complexity. All these observations suggest that adaptive foraging does not always lead to more complex food webs. As a corollary, future studies of food web dynamics should pay careful attention to the choice of type of adaptive foraging model as well as of parameter values. Copyright (c) 2010 Elsevier Ltd.

    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

    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.

  1. Web site lets solar scientists inform and inspire students

    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.

  2. Information organization on the web site of medical library

    Full Text Available A library home page should be a document providing information about library, its various services to and activities for the users. The purpose of the present research was an evaluation of the actual state of-the-art of library home pages of Slovene medical libraries, and a set of suggestions is offered for their improvement. 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.

    2016-01-01

    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.

    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

    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.

    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.

    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.

  20. Public transparency Web sites for radiology practices: prevalence of price, clinical quality, and service quality information.

    Rosenkrantz, Andrew B; Doshi, Ankur M

    2016-01-01

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

    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.

    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.

  4. 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.

    2008-12-09

    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.

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

    1997-02-01

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

    Setton, Robert; Tierney, Christina; Tsai, Tony

    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.

    2016-08-01

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

    2008-10-01

    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.

    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.].

    2012-10-01

    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.

  6. 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.

    2008-05-01

    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.

    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.

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

    2009-01-01

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

    It is still unclear whether there exist functional constraints on the evolution of protein ubiquitination sites, because most previous studies regarded all protein ubiquitination sites as a whole or only focused on limited structural properties. We tried to clarify the relation between functional constraints and ubiquitination sites evolution. We investigated the evolutionary conservation of human ubiquitination sites in a broad evolutionary scale from G. gorilla to S. pombe, and we found that in organisms originated after the divergence of vertebrate, ubiquitination sites are more conserved than their flanking regions, while the opposite tendency is observed before this divergence time. By grouping the ubiquitination proteins into different functional categories, we confirm that many functional constraints like certain molecular functions, protein tissue expression specificity and protein connectivity in protein-protein interaction network enhance the evolutionary conservation of ubiquitination sites. Furthermore, by analyzing the gains of ubiquitination sites at different divergence time and their functional characters, we validate that the emergences of ubiquitination sites at different evolutionary time were also affected by the uncovered functional constraints. The above results suggest that functional constraints on the adaptive evolution of ubiquitination sites increase the opportunity for ubiquitination to synthetically regulate various cellular and developmental processes during evolution.

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.

    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.

    Initializing an effective dictionary is an indispensable step for sparse representation. In this paper, we focus on the dictionary selection problem with the objective to select a compact subset of basis from original training data instead of learning a new dictionary matrix as dictionary learning models do. We first design a new dictionary selection model via l2,0 norm. For model optimization, we propose two methods: one is the standard forward-backward greedy algorithm, which is not suitable for large-scale problems; the other is based on the gradient cues at each forward iteration and speeds up the process dramatically. In comparison with the state-of-the-art dictionary selection models, our model is not only more effective and efficient, but also can control the sparsity. To evaluate the performance of our new model, we select two practical web media summarization problems: 1) we build a new data set consisting of around 500 users, 3000 albums, and 1 million images, and achieve effective assisted albuming based on our model and 2) by formulating the video summarization problem as a dictionary selection issue, we employ our model to extract keyframes from a video sequence in a more flexible way. Generally, our model outperforms the state-of-the-art methods in both these two tasks.

  6. 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

    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.

    Wright, Paul J; McKinley, Christopher J

    2011-01-01

    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.

    Visser, Andre; Mariani, Patrizio; Pigolotti, Simone

    2012-01-01

    We examine the effect of adaptive foraging behaviour within a tri-trophic food web with intra-guild predation. The intra-guild prey is allowed to adjust its foraging effort so as to achieve an optimal per capita growth rate in the face of realized feeding, predation risk and foraging cost. Adaptive...... fitness-seeking behaviour of the intra-guild prey has a stabilizing effect on the tri-trophic food-web dynamics provided that (i) a finite optimal foraging effort exists and (ii) the trophic transfer efficiency from resource to predator via the intra-guild prey is greater than that from the resource...... directly. The latter condition is a general criterion for the feasibility of intra-guild predation as a trophic mode. Under these conditions, we demonstrate rigorously that adaptive behaviour will always promote stability of community dynamics in the sense that the region of parameter space in which...

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

    2011-03-01

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

    2012-01-01

    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.

  19. Adaptive Semantic and Social Web-based learning and assessment environment for the STEM

    Science.gov (United States)

    Babaie, Hassan; Atchison, Chris; Sunderraman, Rajshekhar

    2014-05-01

    We are building a cloud- and Semantic Web-based personalized, adaptive learning environment for the STEM fields that integrates and leverages Social Web technologies to allow instructors and authors of learning material to collaborate in semi-automatic development and update of their common domain and task ontologies and building their learning resources. The semi-automatic ontology learning and development minimize issues related to the design and maintenance of domain ontologies by knowledge engineers who do not have any knowledge of the domain. The social web component of the personal adaptive system will allow individual and group learners to interact with each other and discuss their own learning experience and understanding of course material, and resolve issues related to their class assignments. The adaptive system will be capable of representing key knowledge concepts in different ways and difficulty levels based on learners' differences, and lead to different understanding of the same STEM content by different learners. It will adapt specific pedagogical strategies to individual learners based on their characteristics, cognition, and preferences, allow authors to assemble remotely accessed learning material into courses, and provide facilities for instructors to assess (in real time) the perception of students of course material, monitor their progress in the learning process, and generate timely feedback based on their understanding or misconceptions. The system applies a set of ontologies that structure the learning process, with multiple user friendly Web interfaces. These include the learning ontology (models learning objects, educational resources, and learning goal); context ontology (supports adaptive strategy by detecting student situation), domain ontology (structures concepts and context), learner ontology (models student profile, preferences, and behavior), task ontologies, technological ontology (defines devices and places that surround the

    Science.gov (United States)

    Mehrotra, Ateev; Brannen, Tyler; Sinaiko, Anna D

    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.

    Mason, Alicia; Wright, Kevin B

    2011-02-01

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

    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.

    2015-12-01

    Males of many spider species risk being attacked and cannibalized while searching for, courting, and mating with conspecific females. However, there are exceptions. We show that the funnel-web spider, Hololena curta, has 3 adaptations that minimize risk to males during courtship and mating, and enhance reproductive success. First, males detected chemical or tactile signals associated with webs of virgin females, and differentiated them from webs of mated females, enabling males to increase encounter rates with virgin females and avoid aggressive mated females. Second, males produced stereotyped vibrational signals during courting which induced female quiescence and suppressed female aggression. Third, when touched by males, sexually receptive females entered a cataleptic state, allowing males to safely approach and copulate. Because males can mate multiple times and the sex ratio in natural populations of H. curta is female biased, overall reproductive output is likely increased by males of this species avoiding sexual cannibalism. © 2015 Institute of Zoology, Chinese Academy of Sciences.

    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.

    2014-12-01

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

    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.

    Visser, André W; Mariani, Patrizio; Pigolotti, Simone

    2012-06-07

    We examine the effect of adaptive foraging behaviour within a tri-trophic food web with intra-guild predation. The intra-guild prey is allowed to adjust its foraging effort so as to achieve an optimal per capita growth rate in the face of realized feeding, predation risk and foraging cost. Adaptive fitness-seeking behaviour of the intra-guild prey has a stabilizing effect on the tri-trophic food-web dynamics provided that (i) a finite optimal foraging effort exists and (ii) the trophic transfer efficiency from resource to predator via the intra-guild prey is greater than that from the resource directly. The latter condition is a general criterion for the feasibility of intra-guild predation as a trophic mode. Under these conditions, we demonstrate rigorously that adaptive behaviour will always promote stability of community dynamics in the sense that the region of parameter space in which stability is achieved is larger than for the non-adaptive counterpart of the system.

  11. A study of an adaptive replication framework for orchestrated composite web services.

    2013-01-01

    Replication is considered one of the most important techniques to improve the Quality of Services (QoS) of published Web Services. It has achieved impressive success in managing resource sharing and usage in order to moderate the energy consumed in IT environments. For a robust and successful replication process, attention should be paid to suitable time as well as the constraints and capabilities in which the process runs. The replication process is time-consuming since outsourcing some new replicas into other hosts is lengthy. Furthermore, nowadays, most of the business processes that might be implemented over the Web are composed of multiple Web services working together in two main styles: Orchestration and Choreography. Accomplishing a replication over such business processes is another challenge due to the complexity and flexibility involved. In this paper, we present an adaptive replication framework for regular and orchestrated composite Web services. The suggested framework includes a number of components for detecting unexpected and unhappy events that might occur when consuming the original published web services including failure or overloading. It also includes a specific replication controller to manage the replication process and select the best host that would encapsulate a new replica. In addition, it includes a component for predicting the incoming load in order to decrease the time needed for outsourcing new replicas, enhancing the performance greatly. A simulation environment has been created to measure the performance of the suggested framework. The results indicate that adaptive replication with prediction scenario is the best option for enhancing the performance of the replication process in an online business environment.

    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.

  16. Small bowel adaptation is dependent on site of massive enterectomy.

    1999-06-01

    Changes in amino acid transport after massive enterectomy occur in a nutrient-dependent fashion and may affect long-term outcome. Epidermal growth factor (EGF) can enhance nutrient transport and a defective epidermal growth factor receptor (EGF-R) has been noted to attenuate adaptation. Most animal studies, however, have examined only a single site of resection. This does not mimic the clinical situation where disease dictates the site of resection leading to proximal, middle, or distal enterectomies. We hypothesize that the site of massive enterectomy will alter nutrient transport and EGF-R levels in the residual gut. New Zealand White rabbits were randomized to control, midgut division, or 70% resection (proximal, midgut, or distal). After 1 week, sodium-dependent transport of glucose, glutamine, alanine, and leucine into brush border membrane vesicles was quantitated. EGF-R protein was determined by Western blot analysis. At baseline, amino acid transport was greater in ileum than jejunum. Surgery alone elevated glutamine and leucine jejunal transport by 130 and 97%, respectively, over controls (P < 0.05). Midgut resection increased jejunal glutamine transport 61% over control (P < 0.05). In contrast, distal resection increased jejunal alanine transport by 150% over controls with no change in glutamine (P < 0.05). After midgut resection, EGF-R was significantly greater (124%) in ileum then in jejunum in whole mucosa homogenates. Proximal resection significantly lowered ileal EGF-R compared to that seen in midgut resected residual ileum. Site of massive resection is important in determining postoperative changes in nutrient transport and EGF-R. Copyright 1999 Academic Press.

    Full Text Available Since the first web site was established in August 1991, the number of websites has exceeded 200 million. As of May 2009, there are 191,631 web sites in Turkey. 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. Web sitesi sayısındaki artışa paralel olarak, kayıtlı bilgi miktarı da önemli derecede yükselmiştir. Kullanıcıların bilgiye erişimini kolaylaştıran arama motorları, web sitelerini kataloglamak için üst veriyi kullanmaktadır. Üst veri; veri hakkında veridir.

    This study was designed to evaluate the quality, content, usability, and efficacy of a Web site prepared for the purpose of improving the caregiving capability of family members who provide care for stroke survivors at home. The DISCERN score for the Web site was found to be 4.35 over 5. 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.

    This paper presents an approach for assisting low-literacy readers in accessing Web online information. The "Educational FACILITA" tool is a Web content adaptation tool that provides innovative features and follows more intuitive interaction models regarding accessibility concerns. Especially, we propose an interaction model and a Web application that explore the natural language processing tasks of lexical elaboration and named entity labeling for improving Web accessibility. We report on the results obtained from a pilot study on usability analysis carried out with low-literacy users. The preliminary results show that "Educational FACILITA" improves the comprehension of text elements, although the assistance mechanisms might also confuse users when word sense ambiguity is introduced, by gathering, for a complex word, a list of synonyms with multiple meanings. This fact evokes a future solution in which the correct sense for a complex word in a sentence is identified, solving this pervasive characteristic of natural languages. The pilot study also identified that experienced computer users find the tool to be more useful than novice computer users do.

    2016-03-25

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

  4. Availability of Foodborne Illness Reporting Mechanisms for the Public on Local Health Department Web Sites.

    2017-04-04

    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

    2011-06-01

    Full Text Available The software development process has been directed, over the years, to various methodologies with specific purposes to attend emerging needs. Besides, it can also be noticed, during this period, that some processes require mechanisms related to software reuse and greater speed in the development stage. An important factor in this context is the mutation (adaptation, which occurs in all the software's life cycle, due to its customers' needs or due to technological changes. Regarding the latter factor, it has been observed a significant increase in developments that use distributed applications through the World Wide Web or remote application. Based on the adaptation idea and on the necessity of software distribution systems, this paper presents a technique to reconfigure software capable of acting in several developmental contexts (local, distributed and/or Web. In order to demonstrate its applicability, a case study, through the use of service orientation and remote calls, was done to show the software adaptation in the development of applications. Besides, comparative results among the approaches used in the development of reconfigurable applications are also presented.

    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.

    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

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.

    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.

  14. How did the spider cross the river? Behavioral adaptations for river-bridging webs in Caerostris darwini (Araneae: Araneidae.

    Full Text Available BACKGROUND: Interspecific coevolution is well described, but we know significantly less about how multiple traits coevolve within a species, particularly between behavioral traits and biomechanical properties of animals' "extended phenotypes". In orb weaving spiders, coevolution of spider behavior with ecological and physical traits of their webs is expected. Darwin's bark spider (Caerostris darwini bridges large water bodies, building the largest known orb webs utilizing the toughest known silk. Here, we examine C. darwini web building behaviors to establish how bridge lines are formed over water. We also test the prediction that this spider's unique web ecology and architecture coevolved with new web building behaviors. METHODOLOGY: We observed C. darwini in its natural habitat and filmed web building. We observed 90 web building events, and compared web building behaviors to other species of orb web spiders. CONCLUSIONS: Caerostris darwini uses a unique set of behaviors, some unknown in other spiders, to construct its enormous webs. First, the spiders release unusually large amounts of bridging silk into the air, which is then carried downwind, across the water body, establishing bridge lines. Second, the spiders perform almost no web site exploration. Third, they construct the orb capture area below the initial bridge line. In contrast to all known orb-weavers, the web hub is therefore not part of the initial bridge line but is instead built de novo. Fourth, the orb contains two types of radial threads, with those in the upper half of the web doubled. These unique behaviors result in a giant, yet rather simplified web. Our results continue to build evidence for the coevolution of behavioral (web building, ecological (web microhabitat and biomaterial (silk biomechanics traits that combined allow C. darwini to occupy a unique niche among spiders.

    2007-01-01

    Full Text Available We are on the threshold of a mediamorphosis that will revolutionize the way we interact with our TV sets. The combination between interactive digital TV (IDTV and the Web fosters the development of new interactive multimedia services enjoyable even through a TV screen and a remote control. Yet, several design constraints complicate the deployment of this new pattern of services. Prominent unresolved issues involve macro-problems such as collecting information on the Web based on users' preferences and appropriately presenting retrieved Web contents on the TV screen. To this aim, we propose a system able to dynamically convey contents from the Web to IDTV systems. Our system presents solutions both for personalized Web content search and automatic TV-format adaptation of retrieved documents. As we demonstrate through two case study applications, our system merges the best of IDTV and Web domains spinning the TV mediamorphosis toward the creation of the personal-TV concept.

    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.

    Hoppe, Ian C

    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.

  2. Local adaptation to temperature conserves top-down control in a grassland food web.

    2011-10-22

    A fundamental limitation in many climate change experiments is that tests represent relatively short-term 'shock' experiments and so do not incorporate the phenotypic plasticity or evolutionary change that may occur during the gradual process of climate change. However, capturing this aspect of climate change effects in an experimental design is a difficult challenge that few studies have accomplished. I examined the effect of temperature and predator climate history in food webs composed of herbaceous plants, generalist grasshopper herbivores and spider predators across a natural 4.8°C temperature gradient spanning 500 km in northeastern USA. In these grasslands, the effects of rising temperatures on the plant community are indirect and arise via altered predator-herbivore interactions. Experimental warming had no direct effect on grasshoppers, but reduced predation risk effects by causing spiders from all study sites to seek thermal refuge lower in the plant canopy. However, spider thermal tolerance corresponded to spider origin such that spiders from warmer study sites tolerated higher temperatures than spiders from cooler study sites. As a consequence, the magnitude of the indirect effect of spiders on plants did not differ along the temperature gradient, although a reciprocal transplant experiment revealed significantly different effects of spider origin on the magnitude of top-down control. These results suggest that variation in predator response to warming may maintain species interactions and associated food web processes when faced with long term, chronic climate warming.

    Juan Jose Blazquez-Resino

    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/.

    Pecina, Pavel; Toral, Antonio; Papavassiliou, Vassilis; Prokopidis, Prokopis; Tamchyna, Aleš; Way, Andy; van Genabith, Josef

    In this paper, we tackle the problem of domain adaptation of statistical machine translation (SMT) by exploiting domain-specific data acquired by domain-focused crawling of text from the World Wide Web. We design and empirically evaluate a procedure for automatic acquisition of monolingual and parallel text and their exploitation for system training, tuning, and testing in a phrase-based SMT framework. We present a strategy for using such resources depending on their availability and quantity supported by results of a large-scale evaluation carried out for the domains of environment and labour legislation, two language pairs (English-French and English-Greek) and in both directions: into and from English. In general, machine translation systems trained and tuned on a general domain perform poorly on specific domains and we show that such systems can be adapted successfully by retuning model parameters using small amounts of parallel in-domain data, and may be further improved by using additional monolingual and parallel training data for adaptation of language and translation models. The average observed improvement in BLEU achieved is substantial at 15.30 points absolute.

    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.

    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

    2008-01-01

    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.

    2016-03-02

    The National Health Service (NHS) 70-item inpatient questionnaire surveys inpatients on their perceptions of their hospitalization experience. However, it imposes more burden on the patient than other similar surveys. The literature shows that computerized adaptive testing (CAT) based on item response theory can help shorten the item length of a questionnaire without compromising its precision. Our aim was to investigate whether CAT can be (1) efficient with item reduction and (2) used with quick response (QR) codes scanned by mobile phones. After downloading the 2008 inpatient survey data from the Picker Institute Europe website and analyzing the difficulties of this 70-item questionnaire, we used an author-made Excel program using the Rasch partial credit model to simulate 1000 patients' true scores followed by a standard normal distribution. The CAT was compared to two other scenarios of answering all items (AAI) and the randomized selection method (RSM), as we investigated item length (efficiency) and measurement accuracy. The author-made Web-based CAT program for gathering patient feedback was effectively accessed from mobile phones by scanning the QR code. We found that the CAT can be more efficient for patients answering questions (ie, fewer items to respond to) than either AAI or RSM without compromising its measurement accuracy. A Web-based CAT inpatient survey accessed by scanning a QR code on a mobile phone was viable for gathering inpatient satisfaction responses. With advances in technology, patients can now be offered alternatives for providing feedback about hospitalization satisfaction. This Web-based CAT is a possible option in health care settings for reducing the number of survey items, as well as offering an innovative QR code access.

  15. Truss beam having convex-curved rods, shear web panels, and self-aligning adapters

    Fernandez, Ian M. (Inventor)

    2013-01-01

    A truss beam comprised of a plurality of joined convex-curved rods with self-aligning adapters (SAA) adhesively attached at each end of the truss beam is disclosed. Shear web panels are attached to adjacent pairs of rods, providing buckling resistance for the truss beam. The rods are disposed adjacent to each other, centered around a common longitudinal axis, and oriented so that adjacent rod ends converge to at least one virtual convergence point on the common longitudinal axis, with the rods' curvature designed to increase prevent buckling for the truss beam. Each SAA has longitudinal bores that provide self-aligning of the rods in the SAA, the self-aligning feature enabling creation of strong adhesive bonds between each SAA and the rods. In certain embodiments of the present invention, pultruded unidirectional carbon fiber rods are coupled with carbon fiber shear web panels and metal SAA(s), resulting in a lightweight, low-cost but strong truss beam that is highly resistant to buckling.

    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.

    The hindlimb muscles in four species of Tenrecidae (Oryzoryctinae: Talazac long-tailed tenrec and web-footed tenrec, Tenrecinae: lesser hedgehog tenrec, and streaked tenrec), were examined macroscopically. The weight ratios of the muscles to the body in the oryzoryctinid species are larger than those in Tenrecinae, since the Oryzoryctinae species have an obviously smaller body from the evolutionary point of view. It can be primarily pointed out that the adaptation of the body size is different between the two subfamilies, and secondarily, that functional adaptation to locomotion is complete within each subfamily. The weight data and the morphological findings demonstrate that the web-footed tenrec possesses an extraordinary large M. semimembranosus in comparison to the Talazac long-tailed tenrec in their weight ratios. This muscle may act as a strong flexor motor in the knee joint during the aquatic locomotion of the web-footed tenrec. Since the other muscles of the web-footed tenrec are similar to those of the Talazac long-tailed tenrec regards weight ratio data, we think that the web-footed tenrec may have derived from a terrestrial ancestor such as the long-tailed tenrecs. In Tenrecinae the streaked tenrec is equipped with larger Mm. adductores, M. semimembranosus and M. triceps surae than the lesser hedgehog tenrec. This species is adapted to fossorial life derived from non-specialized ancestors within the evolutionary lines of the spiny tenrecs.

    The Technical Improvement system is an approachable web-based tool that is available to Hanford DOE staff, site contractors, and general support service contractors as part of the baseline optimization effort underway at the Hanford Site. Finding and implementing technical improvements are a large part of DOE’s cost savings efforts. The Technical Improvement dashboard is a key tool for brainstorming and monitoring the progress of submitted baseline optimization and potential cost/schedule efficiencies. The dashboard is accessible to users over the Hanford Local Area Network (HLAN) and provides a highly visual and straightforward status to management on the ideas provided, alleviating the need for resource intensive weekly and monthly reviews.

    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.

    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.

    Full Text Available At large, research universities, a common approach for teaching hundreds of undergraduate students at one time is the traditional, large, lecture-based course. Trends indicate that over the next decade there will be an increase in the number of large, campus courses being offered as well as larger enrollments in courses currently offered. As universities investigate alternative means to accommodate more students and their learning needs, Web-based instruction provides an attractive delivery mode for teaching large, on-campus courses. This article explores a theoretical approach regarding how Web-based instruction can be designed and developed to provide quality education for traditional, on-campus, undergraduate students. The academic debate over the merit of Web-based instruction for traditional, on-campus students has not been resolved. This study identifies and discusses instructional design theory for adapting a large, lecture-based course to the Web.

    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

    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.

    server-based system. Open source web technologies and community-based tools are used to facilitate wide dissemination and adaptation by diverse, independent institutions. The new hydrologic learning modules are based on recent developments in hydrologic modeling, data, and resources. The modules are embedded in three regional-scale ecosystems, Coastal Louisiana, Florida Everglades, and Utah Great Salt Lake Basin. These sites provide a wealth of hydrologic concepts and scenarios that can be used in most water resource and hydrology curricula. The study develops several learning modules based on the three hydro-systems covering subjects such as: water-budget analysis, effects of human and natural changes, climate-hydrology teleconnections, and water-resource management scenarios. The new developments include an instructional interface to give critical guidance and support to the learner and an instructor's guide containing adaptation and implementation procedures to assist instructors in adopting and integrating the material into courses and provide a consistent experience. The design of the new hydrologic education developments will be transferable to independent institutions and adaptable both instructionally and technically through a server system capable of supporting additional developments by the educational community.

    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.

  14. Extracting Reputation Expressions from Web-based Review Sites by Using Causal Relationships

    Science.gov (United States)

    Takano, Atsuko; Ikeoku, Syo-Ta; Kitamura, Yasuhiko

    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.

    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.

    Interventions that target cancer patients and their caregivers have been shown to improve patient-caregiver communication, support, and emotional well-being. To adapt an in-person communication intervention for cancer patients and caregivers to a web-based format, and to examine the usability and acceptability of the web-based program among representative users. A tailored, interactive web-based communication program for cancer patients and their family caregivers was developed based on an existing in-person, nurse-delivered intervention. The development process involved: (1) building a multidisciplinary team of content and web design experts, (2) combining key components of the in-person intervention with the unique tailoring and interactive features of a web-based platform, and (3) conducting focus groups and usability testing to obtain feedback from representative program users at multiple time points. Four focus groups with 2-3 patient-caregiver pairs per group (n = 22 total participants) and two iterations of usability testing with four patient-caregiver pairs per session (n = 16 total participants) were conducted. Response to the program's structure, design, and content was favorable, even among users who were older or had limited computer and Internet experience. The program received high ratings for ease of use and overall usability (mean System Usability Score of 89.5 out of 100). Many elements of a nurse-delivered patient-caregiver intervention can be successfully adapted to a web-based format.

    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.

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

    Science.gov (United States)

    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.

    2007-08-01

    Full Text Available Abstract Background Apollo, a genome annotation viewer and editor, has become a widely used genome annotation and visualization tool for distributed genome annotation projects. When using Apollo for annotation, database updates are carried out by uploading intermediate annotation files into the respective database. This non-direct database upload is laborious and evokes problems of data synchronicity. Results To overcome these limitations we extended the Apollo data adapter with a generic, configurable web service client that is able to retrieve annotation data in a GAME-XML-formatted string and pass it on to Apollo's internal input routine. Conclusion This Apollo web service adapter, Apollo2Go, simplifies the data exchange in distributed projects and aims to render the annotation process more comfortable.

    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.

    Diagnostic imaging is under-represented in medical curricula globally. Adaptive tutorials, online intelligent tutoring systems that provide a personalized learning experience, have the potential to bridge this gap. However, there is limited evidence of their effectiveness for learning about diagnostic imaging. We performed a randomized mixed methods crossover trial to determine the impact of adaptive tutorials on perceived engagement and understanding of the appropriate use and interpretation of common diagnostic imaging investigations. Although concurrently engaged in disparate blocks of study, 99 volunteer medical students (from years 1-4 of the 6-year program) were randomly allocated to one of two groups. In the first arm of the trial on chest X-rays, one group received access to an adaptive tutorial, whereas the other received links to an existing peer-reviewed Web resource. These two groups crossed over in the second arm of the trial, which focused on computed tomography scans of the head, chest, and abdomen. At the conclusion of each arm of the trial, both groups completed an examination-style assessment, comprising questions both related and unrelated to the topics covered by the relevant adaptive tutorial. Online questionnaires were used to evaluate student perceptions of both learning resources. In both arms of the trial, the group using adaptive tutorials obtained significantly higher assessment scores than controls. This was because of higher assessment scores by senior students in the adaptive tutorial group when answering questions related to topics covered in those tutorials. Furthermore, students indicated significantly better engagement with adaptive tutorials than the Web resource and rated the tutorials as a significantly more valuable tool for learning. Medical students overwhelmingly accept adaptive tutorials for diagnostic imaging. The tutorials significantly improve the understanding of diagnostic imaging by senior students. Crown Copyright

    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

    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

    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.

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.

    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.

    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

    2014-07-01

    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.

    The impounding of the Three Gorges Reservoir (TGR) at the Yangtze River caused large flooding of urban, industrial, and agricultural areas, and profound land use changes took place. Consequently, substantial amounts of organic and inorganic pollutants were released into the reservoir. Additionally, contaminants and nutrients are entering the reservoir by drift, drainage, and runoff from adjacent agricultural areas as well as from sewage of industry, aquacultures, and households. The main aim of the presented research project is a deeper understanding of the processes that determines the bioaccumulation and biomagnification of organic pollutants, i.e., mainly pesticides, in aquatic food webs under the newly developing conditions of the TGR. The project is part of the Yangtze-Hydro environmental program, financed by the German Ministry of Education and Science. In order to test combinations of environmental factors like nutrients and pollution, we use an integrated modeling approach to study the potential accumulation and biomagnification. We describe the integrative modeling approach and the consecutive adaption of the AQUATOX model, used as modeling framework for ecological risk assessment. As a starting point, pre-calibrated simulations were adapted to Yangtze-specific conditions (regionalization). Two exemplary food webs were developed by a thorough review of the pertinent literature. The first typical for the flowing conditions of the original Yangtze River and the Daning River near the city of Wushan, and the second for the stagnant reservoir characteristics of the aforementioned region that is marked by an intermediate between lake and large river communities of aquatic organisms. In close cooperation with German and Chinese partners of the Yangtze-Hydro Research Association, other site-specific parameters were estimated. The MINIBAT project contributed to the calibration of physicochemical and bathymetric parameters, and the TRANSMIC project delivered

  8. Evidence that adaptation in Drosophila is not limited by mutation at single sites.

    Directory of Open Access Journals (Sweden)

    Talia Karasov

    2010-06-01

    Full Text Available Adaptation in eukaryotes is generally assumed to be mutation-limited because of small effective population sizes. This view is difficult to reconcile, however, with the observation that adaptation to anthropogenic changes, such as the introduction of pesticides, can occur very rapidly. Here we investigate adaptation at a key insecticide resistance locus (Ace in Drosophila melanogaster and show that multiple simple and complex resistance alleles evolved quickly and repeatedly within individual populations. Our results imply that the current effective population size of modern D. melanogaster populations is likely to be substantially larger (> or = 100-fold than commonly believed. This discrepancy arises because estimates of the effective population size are generally derived from levels of standing variation and thus reveal long-term population dynamics dominated by sharp--even if infrequent--bottlenecks. The short-term effective population sizes relevant for strong adaptation, on the other hand, might be much closer to census population sizes. Adaptation in Drosophila may therefore not be limited by waiting for mutations at single sites, and complex adaptive alleles can be generated quickly without fixation of intermediate states. Adaptive events should also commonly involve the simultaneous rise in frequency of independently generated adaptive mutations. These so-called soft sweeps have very distinct effects on the linked neutral polymorphisms compared to the standard hard sweeps in mutation-limited scenarios. Methods for the mapping of adaptive mutations or association mapping of evolutionarily relevant mutations may thus need to be reconsidered.

  9. Adopting and adapting a commercial view of web services for the Navy

    2005-05-01

    Web Services are being adopted as the enabling technology to provide net-centric capabilities for many Department of Defense operations. The Navy Enterprise Portal, for example, is Web Services-based, and the Department of the Navy is promulgating guidance for developing Web Services. Web Services, however, only constitute a baseline specification that provides the foundation on which users, under current approaches, write specialized applications in order to retrieve data over the Internet. Application development may increase dramatically as the number of different available Web Services increases. Reasons for specialized application development include XML schema versioning differences, adoption/use of diverse business rules, security access issues, and time/parameter naming constraints, among others. We are currently developing for the US Navy a system which will improve delivery of timely and relevant meteorological and oceanographic (MetOc) data to the warfighter. Our objective is to develop an Advanced MetOc Broker (AMB) that leverages Web Services technology to identify, retrieve and integrate relevant MetOc data in an automated manner. The AMB will utilize a Mediator, which will be developed by applying ontological research and schema matching techniques to MetOc forms of data. The AMB, using the Mediator, will support a new, advanced approach to the use of Web Services; namely, the automated identification, retrieval and integration of MetOc data. Systems based on this approach will then not require extensive end-user application development for each Web Service from which data can be retrieved. Users anywhere on the globe will be able to receive timely environmental data that fits their particular needs.

    2008-07-01

    Full Text Available With the advent of the World Wide Web, the Internet has evolved into a user-interactive medium capable of delivering on demand information in high speed. Research into the various methodologies of Web educational applications has been a topic of great interest in the architectural education field. As a course delivery medium, the Web provides the means for creating an integrated, interdisciplinary repository of knowledge available at reasonable cost at anytime, anywhere and to anyone. One of the criteria of an ideal system for facilitating Web-based teaching and learning is to be adaptive. In this paper, we suggest an adaptive Web-based educational model and platform for the architectural design course that supports the main phases of the design process. In particular, the development of the online version of an architectural design course is used as a case study and illustrates the usability of the suggested model.

    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.

  14. Journalism as health education: media coverage of a nonbranded pharma web site.

    2011-03-01

    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.

    Neuhauser, Linda; Rothschild, Rebeccah; Rodríguez, Fátima M

    2007-01-01

    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.

  18. A multi-layered image format for the web with an adaptive layer selection algorithm

    Directory of Open Access Journals (Sweden)

    Tair Milan

    2017-01-01

    Full Text Available In this paper we present a proposed multi-layered image format for use on the web. The format implements an algorithm for selecting adequate layer images depending on the image container's surroundings and size. The layer selection depends on the weighted average brightness of the underlying web page background within the bounds of the image. The proposed image format supports multiple image layers with adjoined thresholds and activation conditions. Depending on these conditions and the underlying background, a layer's visibility will be adequately set. The selection algorithm takes into account the background brightness, each layer's adjoined threshold values, and other newly introduced layer conditions.

    2017-04-01

    The rapid progress of site potential change, caused by the shift of climate zones is a serious problem of lowland management in Southeast Europe. In forestry, the resilience potential of main, climate-dependent tree species (e.g. spruce, beech, sessile oak) and ecosystems is limited at their lower (xeric) limits of distribution. A conventional mitigation measure for adaptive forest management is the return to nature-close management. Severe drought- and biotic impacts in forests indicate however the urgency of fundamental changes in forest policy. To provide assistance in selecting climate-tolerant provenances, species and adaptive technologies for future site conditions is therefore critical. A simplified Decision Support System has been developed for Hungary, keeping conventional elements of site potential assessment. Projections are specified for discrete site types. Processing forest inventory, landcover and geodata, the System provides GIS-supported site information and projections for individual forest compartments, options for tree species better tolerating future climate scenarios as well as their expected yield and risks. Data respectively projections are available for recent and current conditions, and for future reference periods until 2100. Also non-forest site conditions in the novel grassland (steppe) climate zone appear in projections. Experiences for proper management on these sites are however scarce.

    Keshet, Yael

    2010-12-01

    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.

    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.

    Full Text Available Adaptive Educational Hypermedia aims to provide tailored and personalised learning experiences to different students. However, one of its limitations which have resulted in its poor adoption by the e-learning community is the complexity of its authoring process. This paper tries to address this issue in order to push those adaptive systems forward. First, it presents an authoring aid for an existing adaptive system. Lessons learned from this case study are then used to provide a high-level design specification for an authoring tool with an accessible interface to ordinary teachers with limited IT-skills.

    2017-12-01

    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)

    2014-03-01

    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.

  18. Key skills by design: adapting a central Web resource to departmental contexts

    Directory of Open Access Journals (Sweden)

    Claire McAvinia

    2002-12-01

    Full Text Available Web-based delivery of support materials for students has proved to be a popular way of helping small teams to implement key skills policies within universities. The development of 'key' or 'transferable' skills is now encouraged throughout education, but resources (both in terms of staffing and budget tend to be limited. It is difficult for key skills teams to see learners face to face, and not feasible to print or distribute large amounts of paper-based material. Web-based delivery presents a means of overcoming these problems but it can result in generic study skills material simply being published online without due consideration of the needs of different groups of learners within different subject disciplines. Therefore, although a centralized Website for skills provision can overcome logistical problems, it may be perceived as irrelevant or unusable by the student population. This paper presents a model for Web-based delivery of support for key skills which incorporates two separate approaches to the design of these resources. The model was implemented as part of a wider key skills pilot project at University College London, over a period of one year. It includes a 'core' Website, containing information and resources for staff and students. These can also be accessed via customized, departmental key skills homepages. This paper presents the basis for the design choices made in preparing these materials, and the evaluation of some of the pilot departments using them. It then draws some wider conclusions about the effectiveness of this design for supporting skills development.

  20. Site-adapted cultivation of bioenergy crops - a strategy towards a greener and innovative feedstock production

    Science.gov (United States)

    Ruf, Thorsten; Emmerling, Christoph

    2017-04-01

    Cultivation of bioenergy crops is of increasing interest to produce valuable feedstocks e.g. for anaerobic digestion. In the past decade, the focus was primarily set to cultivation of the most economic viable crop, namely maize. In Germany for example, the cultivation area of maize was expanded from approx. 200,000 ha in 2006 to 800,000 ha in 2015. However, this process initiated a scientific and public discussion about the sustainability of intense maize cultivation. Concerns addressed in this context are depletion of soil organic matter, soil erosion and compaction as well as losses of (agro-)biodiversity. However, from a soil science perspective, several problems arise from not site-adapted cultivation of maize. In contrast, the cultivation of perennial bioenergy crops may provide a valuable opportunity to preserve or even enhance soil fertility and agrobiodiversity without limiting economic efficiency. Several perennial energy crops, with various requirements regarding stand conditions, allow a beneficial selection of the most suitable species for a respective location. The study aimed to provide a first step towards a more strategic planning of bioenergy crop cultivation with respect to spatial arrangement, distribution and connectivity of sites on a regional scale. The identification of pedological site characteristics is a crucial step in this process. With the study presented, we tried to derive site information that allow for an assessment of the suitability for specific energy crops. Our idea is to design a multifunctional landscape with a coexistence of sites with reduced management for soil protection and highly productive site. By a site adapted cultivation of perennial energy plants in sensitive areas, a complex, heterogeneous landscape could be reached.

    2016-01-15

    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.

    In this paper, two adaptive Proportional-Integral (PI) control schemes are designed and discussed for control of web tension in Roll-to-Roll (R2R) manufacturing systems. R2R systems are used to transport continuous materials (called webs) on rollers from the unwind roll to the rewind roll. Maintaining web tension at the desired value is critical to many R2R processes such as printing, coating, lamination, etc. Existing fixed gain PI tension control schemes currently used in industrial practice require extensive tuning and do not provide the desired performance for changing operating conditions and material properties. The first adaptive PI scheme utilizes the model reference approach where the controller gains are estimated based on matching of the actual closed-loop tension control systems with an appropriately chosen reference model. The second adaptive PI scheme utilizes the indirect adaptive control approach together with relay feedback technique to automatically initialize the adaptive PI gains. These adaptive tension control schemes can be implemented on any R2R manufacturing system. The key features of the two adaptive schemes is that their designs are simple for practicing engineers, easy to implement in real-time, and automate the tuning process. Extensive experiments are conducted on a large experimental R2R machine which mimics many features of an industrial R2R machine. These experiments include trials with two different polymer webs and a variety of operating conditions. Implementation guidelines are provided for both adaptive schemes. Experimental results comparing the two adaptive schemes and a fixed gain PI tension control scheme used in industrial practice are provided and discussed. Copyright © 2014 ISA.

    Satellite images have great educational potential for teaching on environmental issues and can promote the motivation of young people to enter careers in natural science and technology. Due to the importance and ubiquity of remote sensing in science, industry and the public, the use of satellite imagery has been included into many school curricular in Germany. However, its implementation into school practice is still hesitant, mainly due to lack of teachers' know-how and education materials that align with the curricula. In the project "Space4Geography" a web-based learning platform is developed with the aim to facilitate the application of satellite imagery in secondary school teaching and to foster effective student learning experiences in geography and other related subjects in an interdisciplinary way. The platform features ten learning modules demonstrating the exemplary application of original high spatial resolution remote sensing data (RapidEye and TerraSAR-X) to examine current environmental issues such as droughts, deforestation and urban sprawl. In this way, students will be introduced into the versatile applications of spaceborne earth observation and geospatial technologies. The integrated web-based remote sensing software "BLIF" equips the students with a toolset to explore, process and analyze the satellite images, thereby fostering the competence of students to work on geographical and environmental questions without requiring prior knowledge of remote sensing. This contribution presents the educational concept of the learning environment and its realization by the example of the learning module "Deforestation of the rainforest in Brasil".

    Women Veterans are a rapidly growing population with high risk of exposure to potentially traumatizing events and PTSD diagnoses. Despite the dissemination of evidence-based treatments for PTSD in the VA, most women Veteran VA users underutilize these treatments. Web-based PTSD treatment has the potential to reach and engage women Veterans with PTSD who do not receive treatment in VA settings. Our objective is to modify and evaluate Delivery of Self Training and Education for Stressful Situations (DESTRESSS), a web-based cognitive-behavioral intervention for PTSD, to target PTSD symptoms among women Veterans. The specific aims are to: (1) obtain feedback about DESTRESS, particularly on its relevance and sensitivity to women, using semi-structured interviews with expert clinicians and women Veterans with PTSD, and make modifications based on this feedback; (2) conduct a pilot study to finalize study procedures and make further refinements to the intervention; and (3) conduct a randomized clinical trial (RCT) evaluating a revised, telephone-assisted DESTRESS compared to telephone monitoring only. We describe the results from the first two aims, and the study design and procedures for the ongoing RCT. This line of research has the potential to result in a gender-sensitive, empirically-based, online treatment option for women Veterans with PTSD. Published by Elsevier Inc.

    2010-08-01

    Giant Segmented Mirror Telescopes (GSMT) represents the next generation of extremely large telescopes (ELT). Currently there are three active ELT projects, all established as international partnerships to build telescopes of greater than 20 meters aperture. Two of these have major participation by U.S. institutions: the Giant Magellan Telescope and the Thirty Meter Telescope. The ESO-ELT is under development by the European Southern Observatory and other European institutions. We have developed educational activities to accompany the design phase of these projects. The current activities focus on challenges faced in the design and site selection of a large telescope. The first module is on site selection. This online module is based on the successful Astronomy Village program model. Students evaluate several potential sites to decide where to build the GSMT. They must consider factors such as weather, light pollution, seeing, logistics, and geography. The second project has developed adaptive optics teaching units suitable for high school.

    The urban climate is changing rapidly. Therefore, climate change and its projected impacts on environmental conditions must be considered in assessing and comparing urban planning alternatives. In this paper, we present an integrated framework for urban climate adaptation tool (Urban-CAT) that will help cities to plan for, rather than react to, possible risks. Urban-CAT will be developed as a scenario planning tool that is locally relevant to existing urban decision-making processes.

    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.

    The advances in neuroimaging methods reveal that resting-state functional fMRI (rs-fMRI) connectivity measures can be potential diagnostic biomarkers for autism spectrum disorder (ASD). Recent data sharing projects help us replicating the robustness of these biomarkers in different acquisition conditions or preprocessing steps across larger numbers of individuals or sites. It is necessary to validate the previous results by using data from multiple sites by diminishing the site variations. We investigated partial least square regression (PLS), a domain adaptive method to adjust the effects of multicenter acquisition. A sparse Multivariate Pattern Analysis (MVVPA) framework in a leave one site out cross validation (LOSOCV) setting has been proposed to discriminate ASD from healthy controls using data from six sites in the Autism Brain Imaging Data Exchange (ABIDE). Classification features were obtained using 42 bilateral Brodmann areas without presupposing any prior hypothesis. Our results showed that using PLS, SVM showed poorer accuracies with highest accuracy achieved (62%) than without PLS but not significantly. The regions occurred in two or more informative connections are Dorsolateral Prefrontal Cortex, Somatosensory Association Cortex, Primary Auditory Cortex, Inferior Temporal Gyrus and Temporopolar area. These interrupted regions are involved in executive function, speech, visual perception, sense and language which are associated with ASD. Our findings may support early clinical diagnosis or risk determination by identifying neurobiological markers to distinguish between ASD and healthy controls.

    Current study indicates that Northeastern Tibetan Plateau (NETP) is one of the first widely occupied places by prehistory people on the Tibetan Plateau, which makes NETP very important to understand the human history on the plateau and human adaptation to high elevation environment. Hence, 151 site, a paleo- to Epi-Paleolithic site in the Qinghai Lake basin on NETP, is chosen to excavate. Thousands pieces of animal bones, hundreds pieces of stone artifacts and several possible hearths were unearthed and obtained during two excavation seasons. Carefully redating of the site shows that it was first occupied shortly around 15 ka BP, then reoccupied from 9000-6000 a BP more intensely. Preliminary study of the site suggest that the first appearance of human in Qinghai Lake basin is closely related to the amelioration of the Last Deglaciation and the prevalence of microlithic technology in North China, which may enlighten the study of early human migration on to whole plateau; however, the latter more intense human occupation in 151 site is not only closely related to the warm and stable early-mid Holocene climate but also provoked by early millet agriculture in neighbor low-elevation Loess plateau.

Almost all (95.8% used olive oil as the main added fat, 82.2% and 78.4% reported a low intake of butter and derivatives, and sugary drinks, respectively, and 70.9% referred to an adequate intake of vegetables. On the negative side, 82.3% reported a low intake of legumes, 71.6% a high intake of red meat, 67.6% and 25% lower intake of fruit and nuts, respectively. As regards PA, of the 1221 questionnaires analyzed, 79.4% of the population met the PA health recommendations, 36.5% at a high level, and 42.9% moderate.Conclusions: Web questionnaires can be a useful tool in the promotion and dissemination of both habits. As a suggestion for improvement, we propose the inclusion of demographic variables to determine the profile of users who completed the questionnaires.

    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.

    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.

    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.

    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.

    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.

    Using the response to Mycobacterium butyricum as the test-immune response, the main goal of this study was to demonstrate the suitability of the growing feather (GF) as a dermal test site and window into in vivo cellular/tissue responses (US-Patent 8,216,551). Using M. butyricum immunized chickens, the specific objectives were to: 1) compare the leukocyte infiltration response to intra-dermally injected M. butyricum in GF, wattles, and wing webs; 2) use GF as the test site to monitor leukocyte response profiles to recall antigen in the same individuals; and 3) gain new knowledge regarding the local response to M. butyricum in chickens. For objective 1, chickens were euthanized for tissue collection at 4 to 6, 24, 48, and 72 h after intra-dermal antigen injection. Leukocyte infiltration profiles were determined using immunochemical and conventional histology. Data from this study established the similarities between the cellular response in GF, wattles, and wing webs and uncovered many advantages of working with GF. For objective 2, antigen was injected into multiple GF per individual. GF were collected before and at 0.25, 1, 2, 3, and 7 d post injection and processed for cell population analysis by flow cytometry. Advantages of the approach used in objective 2 included a technically easier, more comprehensive, and more objective leukocyte profile analysis; same-day data acquisition; and, most importantly, easy, minimally invasive sample collection from the same individual throughout the study. Both studies contributed new knowledge regarding the local cutaneous response to M. butyricum in M. butyricum immunized chickens and confirmed the cell-mediated nature of the immune response to M. butyricum (e.g., elevated levels [P < 0.05] of T cells [CD4+ and CD8+], macrophages and MHC class II+-cells on days one to 3 post injection in M. butyricum- compared to PBS-injected tissues). The use of GF as an "in vivo test tube" to monitor local innate and adaptive immune

    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 .

    We investigated the conditions under which plastic responses to density are adaptive in natural populations of Impatiens capensis and determined whether plasticity has evolved differently in different selective environments. Previous studies showed that a population that evolved in a sunny site exhibited greater plasticity in response to density than did a population that evolved in a woodland site. Using replicate inbred lines in a reciprocal transplant that included a density manipulation, we asked whether such population differentiation was consistent with the hypothesis of adaptive divergence. We hypothesized that plasticity would be more strongly favored in the sunny site than in the woodland site; consequently, we predicted that selection would be more strongly density dependent in the sunny site, favoring the phenotype that was expressed at each density. Selection on internode length and flowering date was consistent with the hypothesis of adaptive divergence in plasticity. Few costs or benefits of plasticity were detected independently from the expressed phenotype, so plasticity was selected primarily through selection on the phenotype. Correlations between phenotypes and their plasticity varied with the environment and would cause indirect selection on plasticity to be environment dependent. We showed that an appropriate plastic response even to a rare environment can greatly increase genotypic fitness when that environment is favorable. Selection on the measured characters contributed to local adaptation and fully accounted for fitness differences between populations in all treatments except the woodland site at natural density.

    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.

    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

    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.

    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.

    We examined parameter optimisation in the JSBACH (Kaminski et al., 2013; Knorr and Kattge, 2005; Reick et al., 2013) ecosystem model, applied to two boreal forest sites (Hyytiälä and Sodankylä) in Finland. We identified and tested key parameters in soil hydrology and forest water and carbon-exchange-related formulations, and optimised them using the adaptive Metropolis (AM) algorithm for Hyytiälä with a 5-year calibration period (2000-2004) followed by a 4-year validation period (2005-2008). Sodankylä acted as an independent validation site, where optimisations were not made. The tuning provided estimates for full distribution of possible parameters, along with information about correlation, sensitivity and identifiability. Some parameters were correlated with each other due to a phenomenological connection between carbon uptake and water stress or other connections due to the set-up of the model formulations. The latter holds especially for vegetation phenology parameters. The least identifiable parameters include phenology parameters, parameters connecting relative humidity and soil dryness, and the field capacity of the skin reservoir. These soil parameters were masked by the large contribution from vegetation transpiration. In addition to leaf area index and the maximum carboxylation rate, the most effective parameters adjusting the gross primary production (GPP) and evapotranspiration (ET) fluxes in seasonal tuning were related to soil wilting point, drainage and moisture stress imposed on vegetation. For daily and half-hourly tunings the most important parameters were the ratio of leaf internal CO2 concentration to external CO2 and the parameter connecting relative humidity and soil dryness. Effectively the seasonal tuning transferred water from soil moisture into ET, and daily and half-hourly tunings reversed this process. The seasonal tuning improved the month-to-month development of GPP and ET, and produced the most stable estimates of water use

  9. A socio-ecological adaptive approach to contaminated mega-site management: From 'control and correct' to 'coping with change'

    Mega-sites have a notable impact on surrounding ecological systems. At such sites there are substantial risks associated with complex socio-ecological interactions that are hard to characterize, let alone model and predict. While the urge to control and clean-up mega-sites (control and correct) is understandable, rather than setting a goal of cleaning up such sites, we suggest a more realistic response strategy is to address these massive and persistent sources of contamination by acknowledging their position as new features of the socio-ecological landscapes within which they are located. As it seems nearly impossible to clean up such sites, we argue for consideration of a 'coping with change' rather than a 'control and correct' approach. This strategy recognizes that the current management option for a mega-site, in light of its physical complexities and due to changing societal preferences, geochemical transformations, hydrogeology knowledge and remedial technology options may not remain optimal in future, and therefore needs to be continuously adapted, as community, ecology, technology and understanding change over time. This approach creates an opportunity to consider the relationship between a mega-site and its human and ecological environments in a different and more dynamic way. Our proposed approach relies on iterative adaptive management to incorporate mega-site management into the overall socio-ecological systems of the site's context. This approach effectively embeds mega-site management planning in a triple bottom line and environmental sustainability structure, rather than simply using single measures of success, such as contaminant-based guidelines. Recognizing that there is probably no best solution for managing a mega-site, we present a starting point for engaging constructively with this seemingly intractable issue. Therefore, we aim to initiate discussion about a new approach to mega-site management, in which the complexity of the problems posed

    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.

    The new web-server pocketZebra implements the power of bioinformatics and geometry-based structural approaches to identify and rank subfamily-specific binding sites in proteins by functional significance, and select particular positions in the structure that determine selective accommodation of ligands. A new scoring function has been developed to annotate binding sites by the presence of the subfamily-specific positions in diverse protein families. pocketZebra web-server has multiple input modes to meet the needs of users with different experience in bioinformatics. The server provides on-site visualization of the results as well as off-line version of the output in annotated text format and as PyMol sessions ready for structural analysis. pocketZebra can be used to study structure-function relationship and regulation in large protein superfamilies, classify functionally important binding sites and annotate proteins with unknown function. The server can be used to engineer ligand-binding sites and allosteric regulation of enzymes, or implemented in a drug discovery process to search for potential molecular targets and novel selective inhibitors/effectors. The server, documentation and examples are freely available at http://biokinet.belozersky.msu.ru/pocketzebra and there are no login requirements. © The Author(s) 2014.

  14. An End User Development Approach for Mobile Web Augmentation

    2017-01-01

    Full Text Available The trend towards mobile devices usage has made it possible for the Web to be conceived not only as an information space but also as a ubiquitous platform where users perform all kinds of tasks. In some cases, users access the Web with native mobile applications developed for well-known sites, such as, LinkedIn, Facebook, and Twitter. These native applications might offer further (e.g., location-based functionalities to their users in comparison with their corresponding Web sites because they were developed with mobile features in mind. However, many Web applications have no native counterpart and users access them using a mobile Web browser. Although the access to context information is not a complex issue nowadays, not all Web applications adapt themselves according to it or diversely improve the user experience by listening to a wide range of sensors. At some point, users might want to add mobile features to these Web sites, even if those features were not originally supported. In this paper, we present a novel approach to allow end users to augment their preferred Web sites with mobile features. We support our claims by presenting a framework for mobile Web augmentation, an authoring tool, and an evaluation with 21 end users.

  17. Adaptive evolution of the spike gene of SARS coronavirus: changes in positively selected sites in different epidemic groups

    Directory of Open Access Journals (Sweden)

    He Shao-Heng

    2006-10-01

    Full Text Available Abstract Background It is believed that animal-to-human transmission of severe acute respiratory syndrome (SARS coronavirus (CoV is the cause of the SARS outbreak worldwide. The spike (S protein is one of the best characterized proteins of SARS-CoV, which plays a key role in SARS-CoV overcoming species barrier and accomplishing interspecies transmission from animals to humans, suggesting that it may be the major target of selective pressure. However, the process of adaptive evolution of S protein and the exact positively selected sites associated with this process remain unknown. Results By investigating the adaptive evolution of S protein, we identified twelve amino acid sites (75, 239, 244, 311, 479, 609, 613, 743, 765, 778, 1148, and 1163 in the S protein under positive selective pressure. Based on phylogenetic tree and epidemiological investigation, SARS outbreak was divided into three epidemic groups: 02–04 interspecies, 03-early-mid, and 03-late epidemic groups in the present study. Positive selection was detected in the first two groups, which represent the course of SARS-CoV interspecies transmission and of viral adaptation to human host, respectively. In contrast, purifying selection was detected in 03-late group. These indicate that S protein experiences variable positive selective pressures before reaching stabilization. A total of 25 sites in 02–04 interspecies epidemic group and 16 sites in 03-early-mid epidemic group were identified under positive selection. The identified sites were different between these two groups except for site 239, which suggests that positively selected sites are changeable between groups. Moreover, it was showed that a larger proportion (24% of positively selected sites was located in receptor-binding domain (RBD than in heptad repeat (HR1-HR2 region in 02–04 interspecies epidemic group (p = 0.0208, and a greater percentage (25% of these sites occurred in HR1–HR2 region than in RBD in 03-early

  19. The SURA Coastal Ocean Observing and Prediction (SCOOP) Program: Adapting Web 2.0 technologies to power next generation science

    Science.gov (United States)

    Bogden, P.; Partners, S.

    2008-12-01

    The Web 2.0 has helped globalize the economy and change social interactions, but the full impact on coastal sciences has yet to be realized. The SCOOP program (www.OpenIOOS.org/about/sura.html), an initiative of the Coastal Research Committee of the Southeastern Universities Research Association (SURA), has been using Web 2.0 technologies to create infrastructure for a multi-disciplinary Distributed Coastal Laboratory (DCL). In the spirit of the Web 2.0, SCOOP strives to provide an open-access virtual facility where "virtual visiting" scientists can log in, perform experiments (e.g., evaluate new wetting/drying algorithms in several different inundation models), potentially contribute to the assembly of resources (e.g., leave their algorithms for others), and then move on. The SCOOP prototype has focused on storm surge and waves (the initial science focus), and integrates a real-time data network to evaluate the predictions. The multi-purpose SCOOP components support a sensor-web initiative (www.OOSTethys.org) that is co-led by SURA. SCOOP also includes portals with real-time visualization, workflow configuration and decision-tool prototypes (www.OpenIOOS.org), powered by distributed computing resources from multiple universities across the nation (www.sura.org/SURAgrid). Based on our experience, we propose three key ingredients for initiatives to have the biggest impact on coastal science: (1) standards, (2) working prototypes and (3) communities of interest. We strongly endorse the Open Geospatial Consortium - a geospatial analog of the World Wide Web consortium - and other international consensus-standards bodies that engage government, private sector and academic involvement. But these standards are often highly complex, which can be an impediment to their use. We have overcome such hurdles with the second key ingredient: a focused working prototype. The prototype should include guides and resources that make it easy for others to apply, test, and revise the

    Large dams have been constructed on rivers to meet human demands for water, electricity, navigation, and recreation. As a consequence, flow and temperature regimes have been altered, strongly affecting river food webs and ecosystem processes. Experimental high-flow dam releases, i.e., controlled floods, have been implemented on the Colorado River, USA, in an effort to reestablish pulsed flood events, redistribute sediments, improve conditions for native fishes, and increase understanding of how dam operations affect physical and biological processes. We quantified secondary production and organic matter flows in the food web below Glen Canyon dam for two years prior and one year after an experimental controlled flood in March 2008. Invertebrate biomass and secondary production declined significantly following the flood (total biomass, 55% decline; total production, 56% decline), with most of the decline driven by reductions in two nonnative invertebrate taxa, Potamopyrgus antipodarum and Gammarus lacustris. Diatoms dominated the trophic basis of invertebrate production before and after the controlled flood, and the largest organic matter flows were from diatoms to the three most productive invertebrate taxa (P. antipodarum, G. lacustris, and Tubificida). In contrast to invertebrates, production of rainbow trout (Oncorhynchus mykiss) increased substantially (194%) following the flood, despite the large decline in total secondary production of the invertebrate assemblage. This counterintuitive result is reconciled by a post-flood increase in production and drift concentrations of select invertebrate prey (i.e., Chironomidae and Simuliidae) that supported a large proportion of trout production but had relatively low secondary production. In addition, interaction strengths, measured as species impact values, were strongest between rainbow trout and these two taxa before and after the flood, demonstrating that the dominant consumer—resource interactions were not

    Image-guided radiotherapy (IGRT), based on radiopaque markers placed in the prostate gland, was used for proton therapy of prostate patients. Orthogonal X-rays and the IBA Digital Image Positioning System (DIPS) were used for setup correction prior to treatment and were repeated after treatment delivery. Following a rationale for margin estimates similar to that of van Herk,(1) the daily post-treatment DIPS data were analyzed to determine if an adaptive radiotherapy plan was necessary. A Web application using ASP.NET MVC5, Entity Framework, and an SQL database was designed to automate this process. The designed features included state-of-the-art Web technologies, a domain model closely matching the workflow, a database-supporting concurrency and data mining, access to the DIPS database, secured user access and roles management, and graphing and analysis tools. The Model-View-Controller (MVC) paradigm allowed clean domain logic, unit testing, and extensibility. Client-side technologies, such as jQuery, jQuery Plug-ins, and Ajax, were adopted to achieve a rich user environment and fast response. Data models included patients, staff, treatment fields and records, correction vectors, DIPS images, and association logics. Data entry, analysis, workflow logics, and notifications were implemented. The system effectively modeled the clinical workflow and IGRT process.

  7. Adaptation of a web-based, open source electronic medical record system platform to support a large study of tuberculosis epidemiology

    2012-11-01

    Full Text Available Abstract Background In 2006, we were funded by the US National Institutes of Health to implement a study of tuberculosis epidemiology in Peru. The study required a secure information system to manage data from a target goal of 16,000 subjects who needed to be followed for at least one year. With previous experience in the development and deployment of web-based medical record systems for TB treatment in Peru, we chose to use the OpenMRS open source electronic medical record system platform to develop the study information system. Supported by a core technical and management team and a large and growing worldwide community, OpenMRS is now being used in more than 40 developing countries. We adapted the OpenMRS platform to better support foreign languages. We added a new module to support double data entry, linkage to an existing laboratory information system, automatic upload of GPS data from handheld devices, and better security and auditing of data changes. We added new reports for study managers, and developed data extraction tools for research staff and statisticians. Further adaptation to handle direct entry of laboratory data occurred after the study was launched. Results Data collection in the OpenMRS system began in September 2009. By August 2011 a total of 9,256 participants had been enrolled, 102,274 forms and 13,829 laboratory results had been entered, and there were 208 users. The system is now entirely supported by the Peruvian study staff and programmers. Conclusions The information system served the study objectives well despite requiring some significant adaptations mid-stream. OpenMRS has more tools and capabilities than it did in 2008, and requires less adaptations for future projects. OpenMRS can be an effective research data system in resource poor environments, especially for organizations using or considering it for clinical care as well as research.

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

    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.

    Full Text Available Precise genome editing using engineered nucleases can significantly facilitate biological studies and disease treatment. In particular, clustered regularly interspaced short palindromic repeats (CRISPR with CRISPR-associated (Cas proteins are a potentially powerful tool for modifying a genome by targeted cleavage of DNA sequences complementary to designed guide strand RNAs. Although CRISPR/Cas systems can have on-target cleavage rates close to the transfection rates, they may also have relatively high off-target cleavage at similar genomic sites that contain one or more base pair mismatches, and insertions or deletions relative to the guide strand. We have developed a bioinformatics-based tool, COSMID (CRISPR Off-target Sites with Mismatches, Insertions, and Deletions that searches genomes for potential off-target sites (http://crispr.bme.gatech.edu. Based on the user-supplied guide strand and input parameters, COSMID identifies potential off-target sites with the specified number of mismatched bases and insertions or deletions when compared with the guide strand. For each site, amplification primers optimal for the chosen application are also given as output. This ranked-list of potential off-target sites assists the choice and evaluation of intended target sites, thus helping the design of CRISPR/Cas systems with minimal off-target effects, as well as the identification and quantification of CRISPR/Cas induced off-target cleavage in cells.

  18. Web-based GIS for collaborative planning and public participation: an application to the strategic planning of wind farm sites.

    Spatial planning typically involves multiple stakeholders. To any specific planning problem, stakeholders often bring different levels of knowledge about the components of the problem and make assumptions, reflecting their individual experiences, that yield conflicting views about desirable planning outcomes. Consequently, stakeholders need to learn about the likely outcomes that result from their stated preferences; this learning can be supported through enhanced access to information, increased public participation in spatial decision-making and support for distributed collaboration amongst planners, stakeholders and the public. This paper presents a conceptual system framework for web-based GIS that supports public participation in collaborative planning. The framework combines an information area, a Multi-Criteria Spatial Decision Support System (MC-SDSS) and an argumentation map to support distributed and asynchronous collaboration in spatial planning. After analysing the novel aspects of this framework, the paper describes its implementation, as a proof of concept, in a system for Web-based Participatory Wind Energy Planning (WePWEP). Details are provided on the specific implementation of each of WePWEP's four tiers, including technical and structural aspects. Throughout the paper, particular emphasis is placed on the need to support user learning throughout the planning process.

    Full Text Available This paper discusses the last segment of a three-year interdisciplinary and intersectoral action research on climate change and urban transformation. The project had, as one of its core missions, the role of imagining urban and architectural adaptations for urban neighbourhoods that would contribute to minimizing the negative impacts of climate change on people’s comfort, health and safety. The first part of the paper describes the collaborative design and augmented participation method used in the context of Québec City, Canada. These include the design process conducted to imagine adaptation scenarios, the visual strategies undertaken to make these understandable for the population, and the Web 2.0 crowdsourcing approach forwarded to measure feasibility and social acceptability of the design and visualization strategies. The second part discusses three positive outcomes of the process. First, collaborative design conducted with intersectoral groups of experts constitutes a promising avenue to identify adaptations and evaluate their relevance. Second, crowdsourcing is a powerful tool to inform the general public about climate change including both negative and potential aspects. As well, the crowdsource model allows access to particular knowledge which empowered users to make changes around their homes and neighbourhoods or advocating action from their local government. Crowdsourcing is also an efficient tool to help understand what people know about the potential impact of climate change and how it bears on their comfort, health and safety. Third and finally, the design proposals and the evaluation comments generated by working closely with various stakeholders, along with the public on-line consultation, allow for the induction of pragmatic recommendations that can be used as decision aids by elected officials and civil servants to better prepare their municipalities for climate change.

    Since February 2002, the French authority of nuclear safety (ASN) publishes on its web site (http://www.asn.gouv.fr) the letters addressed to the operators of nuclear facilities at the end of its inspections. The ASN carries out about 700 inspections every year which concern the French nuclear facilities, the central services of nuclear operators or of their suppliers, and the transports of nuclear materials. Each inspection is followed by a follow-up letter which mentions all anomalies noticed during the inspection and eventually asks for some remedial actions or for some complements of information. This document brings together the letters published between february and May 2002 and concerning the on-site inspections of nuclear facilities (EdF nuclear power plants, CEA centers, Cogema facilities, other sites) and the off-site inspections (Andra, transports of nuclear materials).

    This study describes the extent to which chiropractors with Web sites practicing in Canada advertise health products for sale and considers this practice in the context of chiropractic codes of ethics and conduct. Chiropractic Web sites in Canada were identified using a public online business directory (Canada 411). The Web sites were searched, and an inventory of the health products for sale was taken. The influences of type of practice and province of practice on the sale of health product were assessed. Textual comments about health product marketing were summarized. National and provincial codes of ethics were reviewed, and the content on health product advertising was summarized. Two hundred eighty-seven Web sites were reviewed. Just more than half of the Web sites contained information on health products for sale (n = 158, 54%). Orthotics were advertised most often (n = 136 practices, 47%), followed by vitamins/nutritional supplements (n = 53, 18%), pillows and supports (n = 40, 14%), and exercise/rehabilitation products (n = 20, 7%). Chiropractors in solo or group chiropractic practices were less likely to advertise health products than those in multidisciplinary practice (P ethics and conduct varied in their guidelines regarding health product sales. Variations in codes of ethics and in the proportions of practitioners advertising health products for sales across the country suggest that opinions may be divided on the acceptability of health product sales. Such practices raise questions and considerations for the chiropractic profession.

    Adaptive learning platforms (ALPs) can revolutionize medical education by making learning more efficient, but their potential has not been realized because students do not use them persistently. We applied educational data mining methods to study United States medical students who used an ALP called Osmosis ( www.osmosis.org ) from 1 August 2014 to 31 July 2015. Multivariate logistic regressions modeled persistence on Osmosis as the dependent variable and Osmosis-collected variables as predictors. The 6787 students included in our analysis responded to a total of 887,193 items, with 2138 (31.5%) using Osmosis persistently. Number of items per student, mobile device use, subscription payment, and group membership were independently associated with persisting (p < 0.001 in all models). Persistent users rated quality more favorably (p < 0.01) but were not more confident in answer selections (p = 0.80). While persisters were more accurate than non-persisters (55% (SD 18%) vs 52% (SD 22%), p < 0.001), after adjusting for number of items, lower accuracy was associated with persistent use (OR 0.93 [95% CI 0.90-0.97], p < 0.01). Our study of a large sample of U.S. medical students illustrates big data medical education research and provides guidance for improving implementation of ALPs and further investigation.

    Understanding how and why populations evolve is of fundamental importance to molecular ecology. Restriction site-associated DNA sequencing (RADseq), a popular reduced representation method, has ushered in a new era of genome-scale research for assessing population structure, hybridization, demographic history, phylogeography and migration. RADseq has also been widely used to conduct genome scans to detect loci involved in adaptive divergence among natural populations. Here, we examine the capacity of those RADseq-based genome scan studies to detect loci involved in local adaptation. To understand what proportion of the genome is missed by RADseq studies, we developed a simple model using different numbers of RAD-tags, genome sizes and extents of linkage disequilibrium (length of haplotype blocks). Under the best-case modelling scenario, we found that RADseq using six- or eight-base pair cutting restriction enzymes would fail to sample many regions of the genome, especially for species with short linkage disequilibrium. We then surveyed recent studies that have used RADseq for genome scans and found that the median density of markers across these studies was 4.08 RAD-tag markers per megabase (one marker per 245 kb). The length of linkage disequilibrium for many species is one to three orders of magnitude less than density of the typical recent RADseq study. Thus, we conclude that genome scans based on RADseq data alone, while useful for studies of neutral genetic variation and genetic population structure, will likely miss many loci under selection in studies of local adaptation. © 2016 John Wiley & Sons Ltd.

    The Euro-Argo education website (www.euroargo-edu.org) aims to make Argo and its data accessible to a non-specialist audience. The site is centred on a selection of floats, which have been chosen because of the insight they provide into key oceanographic processes, the physical and biogeochemical characteristics of different ocean regions around the world, and the role of the ocean in the global climate system. The float selection is a vehicle for teaching data analysis skills, linking these to current topics in the ocean and climate sciences. Each float in the selection has its own page, which provides access to the float data, data plots, background information on the ocean region in which the float can be found, and questions to guide data interpretation. Hidden 'model answers' allow users to check their understanding by comparing their own answers to those provided. The interactive component of the site also includes a series of quizzes, designed to teach data interpretation skills. These start at a basic level and take the students step by step through the most common ways to plot oceanographic data in space and time. More general background information covers the main aspects of the Argo programme, its history and applications, and basic technical information about the floats and sensors. 'World Tour' pages linked to the float selection provide information about the main ocean regions and link information from the Argo programme to oceanographic information from other sources such as satellite observations. The site is primarily aimed at young people between 11 and 18 years of age. However experience from using selected material from the site during science open days shows that children as young as 8-9 and adults of all ages also enjoy the challenge of using and interpreting the Argo data in different contexts.

    Full Text Available Abstract Background The increasing popularity and use of the internet makes it an attractive option for providing health information and treatment, including alcohol/other drug use. There is limited research examining how people identify and access information about alcohol or other drug (AOD use online, or how they assess the usefulness of the information presented. This study examined the strategies that individuals used to identify and navigate a range of AOD websites, along with the attitudes concerning presentation and content. Methods Members of the general community in Brisbane and Roma (Queensland, Australia were invited to participate in a 30-minute search of the internet for sites related to AOD use, followed by a focus group discussion. Fifty one subjects participated in the study across nine focus groups. Results Participants spent a maximum of 6.5 minutes on any one website, and less if the user was under 25 years of age. Time spent was as little as 2 minutes if the website was not the first accessed. Participants recommended that AOD-related websites should have an engaging home or index page, which quickly and accurately portrayed the site's objectives, and provided clear site navigation options. Website content should clearly match the title and description of the site that is used by internet search engines. Participants supported the development of a portal for AOD websites, suggesting that it would greatly facilitate access and navigation. Treatment programs delivered online were initially viewed with caution. This appeared to be due to limited understanding of what constituted online treatment, including its potential efficacy. Conclusions A range of recommendations arise from this study regarding the design and development of websites, particularly those related to AOD use. These include prudent use of text and information on any one webpage, the use of graphics and colours, and clear, uncluttered navigation options

    Previous studies have identified inconsistencies in physician conflict-of-interest disclosures at academic meetings. The Physician Payment Sunshine Act (PPSA) will require industry to disclose anything of value given to physicians by 2014. In preparation, some spine device companies have begun reporting payments online. To evaluate potential inconsistencies between physician disclosures and payments reported by industry before the PPSA implementation. Comparison of publically available disclosure/payment data. Physicians participating in the 2011 North American Spine Society (NASS) annual meeting and physicians listed on the 2010 physician payment web sites of Medtronic and Depuy Spine. Disclosures of participants at NASS were compared with the published Medtronic and Depuy Spine physician payments. The periods reflected by the disclosures compared should have coincided (except the Depuy site, which was only listed for one quarter of the NASS disclosure period). Discrepancies were noted whenever participant disclosures and company listings did not match as well as whenever payment ranges did not overlap. Fisher's exact test was used to compare disclosure discrepancy rates based on Medtronic payment size. No funding was received for this work. The authors report no conflicts of interest directly related to this study; however, one of the authors does do consulting unrelated to this study. Medtronic and Depuy Spine were disclosed by 12.1% and 8.75% of NASS participants, respectively. Based on NASS disclosures, 52.4% of NASS participants affiliated with Medtronic had their disclosures inaccurately reflected on the Medtronic web site. Based on Medtronic payment postings, 45.7% of NASS participants listed on Medtronic's webpage had discrepancies in their NASS disclosures. Those who received payments $100,000 (p=.009). Based on Depuy Spine payment postings, 30% of NASS participants listed on Depuy Spine's site had discrepancies in their NASS disclosures. Discrepancy

    Biogeochemistry in marine plankton communities is strongly influenced by the activities of microbial species. Understanding the composition and dynamics of these assemblages is essential for modeling emergent community-level processes, yet few studies have examined all of the biological assemblages present in the plankton, and benchmark data of this sort from time-series studies are rare. Abundance and biomass of the entire microbial assemblage and mesozooplankton (>200 μm) were determined vertically, monthly and seasonally over a 3-year period at a coastal time-series station in the San Pedro Basin off the southwestern coast of the USA. All compartments of the planktonic community were enumerated (viruses in the femtoplankton size range [0.02-0.2 μm], bacteria + archaea and cyanobacteria in the picoplankton size range [0.2-2.0 μm], phototrophic and heterotrophic protists in the nanoplanktonic [2-20 μm] and microplanktonic [20-200 μm] size ranges, and mesozooplankton [>200 μm]. Carbon biomass of each category was estimated using standard conversion factors. Plankton abundances varied over seven orders of magnitude across all categories, and total carbon biomass averaged approximately 60 μg C l-1 in surface waters of the 890 m water column over the study period. Bacteria + archaea comprised the single largest component of biomass (>1/3 of the total), with the sum of phototrophic protistan biomass making up a similar proportion. Temporal variability at this subtropical station was not dramatic. Monthly depth-specific and depth-integrated biomass varied 2-fold at the station, while seasonal variances were generally web structure and function at this coastal observatory.

    Biological and artificial molecules and assemblies capable of supramolecular recognition, especially those with nucleobase pairing, usually rely on autonomous or collective binding to function. Advanced site-specific recognition takes advantage of cooperative spatial effects, as in local folding in protein-DNA binding. Herein, we report a new nucleobase-tagged metal-organic framework (MOF), namely ZnBTCA (BTC=benzene-1,3,5-tricarboxyl, A=adenine), in which the exposed Watson-Crick faces of adenine residues are immobilized periodically on the interior crystalline surface. Systematic control experiments demonstrated the cooperation of the open Watson-Crick sites and spatial effects within the nanopores, and thermodynamic and kinetic studies revealed a hysteretic host-guest interaction attributed to mild chemisorption. We further exploited this behavior for adenine-thymine binding within the constrained pores, and a globally adaptive response of the MOF host was observed. © 2015 WILEY-VCH Verlag GmbH & Co.
