    2012-07-01

    Full Text Available Web browser is one of the most important internet facilities for surfing the internet. A good web browser must incorporate literally tens of features such as integrated search engine, automatic updates, etc. Each year, ten web browsers are formally introduced as top best reviewers by some organizations. In this paper, we propose the implementation of TOPSIS technique to rank ten web browsers. The proposed model of this paper uses five criteria including speed, features, security, technical support and supported configurations. In terms of speed, Safari is the best web reviewer followed by Google Chrome and Internet Explorer while Opera is the best web reviewer when we look into 20 different features. We have also ranked these web browsers using all five categories together and the results indicate that Opera, Internet explorer, Firefox and Google Chrome are the best web browsers to be chosen.

    2011-11-01

    The development of the Internet and its gradual mass distribution in the last 20 years have marked the beginning of a global revolution in the way of communicating and thinking. In this context, emerged disorders related to a pathological use of the network, up to forms of real addiction (Internet Addiction Disorder), similar to the use of psychotropic substances. The abuse of the Internet can seriously aggravate pre-existing psychopathological traits, which are the basis of addiction, resulting in a continuous process of disconnection from reality. The loss of interpersonal relationships, the change of mood, cognition completely oriented to the use of the network and disruption of temporal experience are common features in patients addicted to the Internet. There are also clear signs of intoxication and abstinence. Teenagers are particularly at risk, maybe because born in the "new virtual world" and therefore less aware of the risks that may ensue. At the Gemelli Hospital in Rome it's active an out-patient service for Internet Addiction Disorder with a treatment protocol that includes individual interviews, group rehabilitation and self-help groups for family members.

    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 Editable Web sites may contain inaccurate, incomplete, and/or outdated information that may mislead the public's perception of the topic.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.

    Griffith, J.A.; Egbert, S.L.

    2001-01-01

    Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

    Full Text Available This paper presents a project of Web-based Distance Learning support system. The system has been built based on the Internet and World Wide Web facility. The system could be accessed with a web browser which is directed to a certain web server address so that students can do learning process just like in the real situation, such as student admissions, taking course materials, syllabus, assignments, students grades, class discussions through web, and doing online quizzes. Students could also join collaboration works by giving opinions, feedback and student produced paper/web which can be shared to the entire learning community. Therefore, it will build a collaborative learning environment where lectures together with students make constructive knowledge databases for entire learning community. This system has been developed based on Active Server Pages (ASP technology from Microsoft which is embedded in a web server. Web pages reside in a web server which is connected to an SQL Database Server. Database server is used to store structured data such as lectures/students personal information, course lists, syllabus and its descriptions, announcement texts from lecturers, commentaries for discussion forum, student's study evaluations, scores for each assignment, quizzes for each course, assignments text from lectures, assignments which are collected by students and students contribution/materials. This system has been maintained by an administrator for maintaining and developing web pages using HTML. The administrator also does ASP scripts programming to convert web pages into active server pages. Lectures and students could contribute some course materials and share their ideas through their web browser. This web-based collaborative learning system gives the students more active role in the information gathering and learning process, making the distance students feel part of a learning community, therefore increasing motivation, comprehension and

    'In much the same way that HTML and HTTP enabled WWW, the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE), envisioned in 2001 [1] will allow sensor webs to become a reality.'. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not a simple task. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. SWE standardizes web service interfaces, sensor descriptions and data encodings as building blocks for a Sensor Web. SWE standards are now mature specifications (version 2.0) with approved OGC compliance test suites and tens of independent implementations. Many earth and space science organizations and government agencies are using the SWE standards to publish and share their sensors and observations. While SWE has been demonstrated very effective for scientific sensors, its complexity and the computational overhead may not be suitable for resource-constrained tiny sensors. In June 2012, a new OGC Standards Working Group (SWG) was formed called the Sensor Web Interface for Internet of Things (SWE-IoT) SWG. This SWG focuses on developing one or more OGC standards for resource-constrained sensors and actuators (e.g., Internet of Things devices) while leveraging the existing OGC SWE standards. In the near future, billions to trillions of small sensors and actuators will be embedded in real- world objects and connected to the Internet facilitating a concept called the Internet of Things (IoT). By populating our environment with real-world sensor-based devices, the IoT is opening the door to exciting possibilities for a variety of application domains, such as environmental monitoring, transportation and logistics, urban informatics, smart cities, as well as personal and social applications. The current SWE-IoT development aims on modeling the IoT components and defining a standard web service that makes the

    Emergence of a new company, Q9 Networks Inc., that builds secure homes for the paraphernalia of the Web, the equipment and connections essential for digital business systems, is discussed. Q9 data centres offer digital and physical Internet security unequalled by any other existing system. The control room, staffed around the clock, seven days a week, monitors the systems of Q9 and its clients, connected to more than 30 Web service providers, and can switch among them instantly should anyone of them falter. Expert help is also on 24-hour call. Physical protection is equally impressive, with stainless steel walls, visual inspection by video camera of anyone seeking entry, triple sliding doors of stainless steel, bullet-proof glass, monitored by security guards; these are some of the distinguishing features of Q9 data centres. Inside, biometric locking devices, which use a combination of fingerprint and body weight to identify authorized personnel, biometrically shielded and protected data files, back-up power connections plus diesel generators and 50,000 litres of fuel, are further indicators of the 'extreme' protection Q9 data centres provide to their clients' data. The need for Q9 data centres is well established in the oil patch; similar centres in Ottawa, Vancouver and Montreal are on the company's expansion agenda.

    Full Text Available O objetivo desse estudo é analisar o uso de informação latente contida na Internet, em investigações no campo das Ciências Sociais e da Educação. Não se trata de recolher dados “através da Internet”, por exemplo, por meio de questionários. Tampouco são utilizados dados pré-existentes na Internet. São estudos que analisam documentos contidos na Internet, extraindo os dados a partir de análises desses documentos. Pode-se dizer que se trata de um modelo de investigação de “traços”, “cursos” ou “restos” deixados pelos usuários da Internet. Para tanto, foram consultados artigos de pesquisas realizadas a partir desse corpus latente, centrando-se em quatro questões: o que se pode investigar, qual é o contexto em que se encontram estes dados, como selecionar as amostras, que considerações éticas devem ser consideradas? A análise do contexto distingue entre estudos sobre um conteúdo e estudos sobre interação. Também analisa as diferenças entre os sítios “voltados à notícia” e os “voltados ao documento”. São analisadas, em continuidade, os três tipos de populações e os processos de extração das amostras, incluindo a necessidade de correções a posteriori. As conclusões do estudo ressaltam de modo sucinto as possibilidades e oportunidades, assim como os limites desse tipo de investigação. This study aims to analyse the use of latent information in the Internet, as basis for the research in Educational and Social Sciences. Such work is distinguished from those that collect the data “through Internet”, e.g. with questionnaires or forms. It also differs from those using data stored in the Internet. We work with studies that analyse documents in the Internet, extracting data from the analysis of these documents. These documents were once distributed through the Web not knowing this future use as research objects. We can say that it is a research model based on trails left by Internet users

    The Web Experiment List (http://genpsylab-wexlist.unizh.ch/), a free Web-based service for the recruitment of participants in Internet-based experiments, is presented. The Web Experiment List also serves as a searchable archive for the research community. It lists more than 250 links to and descriptions of current and past Web experiments. Searches can be conducted by area of research, language, type of study, date, and status (active vs. archived). Data from log file analyses reveal an increasing use of the Web Experiment List and provide a picture of the distribution of the use of the Web experiment method across disciplines. On a general theoretical note, Web services are discussed as a viable software alternative to the traditional program format.

    Full Text Available Neste artigo discutem-se as possibilidades que as redes sociais introduzem na vida amorosa de adolescentes. As novas tecnologias de comunicação influenciam a subjetividade, assim como mudam hábitos de vida e os modos de as pessoas se relacionarem, incluindo-se as relações amorosas. A adolescência é um momento decisivo na vida em que o sujeito procura estratégias para assegurar uma marca de identificação, sendo os amigos sua principal fonte para tal. A busca pelo parceiro amoroso é também fundamental, e as novas ofertas de instrumentos para tal devem impactar ações, pensamentos e imaginários. A partir do relato de caso publicado, trabalharam-se neste texto as conexões entre internet, adolescência e construção de relações amorosas. Observou-se que a iniciação afetivo-sexual pode ser facilitada pela internet, pois com ela os adolescentes podem dar maior vazão às fantasias e se sentir mais livres, destituídos das barreiras que dificultam as relações. Entretanto, também estão presentes desafios inerentes aos relacionamentos amorosos, sejam presenciais ou virtuais.

    1997-11-01

    Recent developments in Internet technologies are changing and enhancing how one processes and exchanges information. These developments include software and hardware in support of multimedia applications on the World Wide Web. In this paper the authors describe these technologies as they have applied them to remote monitoring and show how they will allow the International Atomic Energy Agency to efficiently review and analyze remote monitoring data for verification of material movements. The authors have developed demonstration software that illustrates several safeguards data systems using the resources of the Internet and Web to access and review data. This Web demo allows the user to directly observe sensor data, to analyze simulated safeguards data, and to view simulated on-line inventory data. Future activities include addressing the technical and security issues associated with using the Web to interface with existing and planned monitoring systems at nuclear facilities. Some of these issues are authentication, encryption, transmission of large quantities of data, and data compression.

    2017-02-01

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

    Directory of Open Access Journals (Sweden)

    2008-05-01

    Full Text Available The term Web 2.0 has recently come to form part of the vocabulary associated with the internet. Semantically imprecise, it looks to capture a moment in the development of the internet where the user becomes the central catalyst with a greater capacity for expression, interaction and participation provided by certain recently developed technologies. Despite this, certain figures and experts are critical of the current course, which they accuse of leading to a whole series of effects that, far from being desirable, bring into question the ideal nature of the evolution of the internet. Expressions such as cultural levelling, cult of the amateur or collective intelligence (used pejoratively have formed around the term Web 2.0 producing an aureole of dystopic resonance.This article looks to relativise some of the arguments that form part of the dystopic view of the Web 2.0, reflecting on the internet from an alternative perspective that helps understand the phenomenon without being overcome by the pessimism that it seems to be subject to in terms of the views of certain experts. Far from presupposing a telos dictating its evolution, the article defends an idea of the internet as a pragmatic field for experimentation that is legitimate as a "path" rather than a "destination" in terms of an implicit or expected development.

    2001-02-01

    Psychology is increasingly interested in understanding the characteristics of the Internet and its effects on people, groups and organizations. However, studying the Internet is not a simple task. First, the Internet is a medium that can be experienced in many different ways. Though a computer and keyboard are usually the mediator of our Internet experience, there are different ways in which users can explore the Internet, present themselves, and communicate using it. Second, the Internet is a social and cognitive space. The handling of information is linked to the activation of psychosocial relationships in which cognitions are elaborated. This happens inside a rather special kind of container--Cyberspace--which tends to rarefy the structural and process features of communication. Third, the Internet experience is always situated in a specific context, even when we are chatting alone in a room. In this sense it can only be fully understood through detailed analysis of the social context in which it happens. Starting from a general three-level model of interpersonal interaction in the Web, this paper tries to define a model of data analysis (Complementary Explorative Multilevel Data Analysis--CEMDA) suited to the constraints of Internet research. The main characteristics of the model are: the focus on different frames and objects for each considered unit of research; the mixed use of quantitative and qualitative tools; and the final integration of results in a general framework.

  3. Internet use in pregnancy informs women's decision making: a web-based survey.

    2010-06-01

    Internet access and usage is almost ubiquitous, providing new opportunities and increasing challenges for health care practitioners and users. With pregnant women reportedly turning to the Internet for information during pregnancy, a better understanding of this behavior is needed. The objective of this study was to ascertain why and how pregnant women use the Internet as a health information source, and the overall effect it had on their decision making. Kuhlthau's (1993) information-seeking model was adapted to provide the underpinning theoretical framework for the study. The design was exploratory and descriptive. Data were collected using a valid and reliable web-based questionnaire. Over a 12-week period, 613 women from 24 countries who had confirmed that they had used the Internet for pregnancy-related information during their pregnancy completed and submitted a questionnaire. Most women (97%) used search engines such as Google to identify online web pages to access a large variety of pregnancy-related information and to use the Internet for pregnancy-related social networking, support, and electronic commerce (i.e., e-commerce). Almost 94 percent of women used the Internet to supplement information already provided by health professionals and 83 percent used it to influence their pregnancy decision making. Nearly half of the respondents reported dissatisfaction with information given by health professionals (48.6%) and lack of time to ask health professionals questions (46.5%) as key factors influencing them to access the Internet. Statistically, women's confidence levels significantly increased with respect to making decisions about their pregnancy after Internet usage (p < 0.05). In this study, the Internet played a significant part in the respondents' health information seeking and decision making in pregnancy. Health professionals need to be ready to support pregnant women in online data retrieval, interpretation, and application.

    Finkelstein, Joseph; Bedra, McKenzie

    2013-01-01

    Internet provides access to vast amounts of comprehensive information regarding any health-related subject. Patients increasingly use this information for health education using a search engine to identify education materials. An alternative approach of health education via Internet is based on utilizing a verified web site which provides structured interactive education guided by adult learning theories. Comparison of these two approaches in older patients was not performed systematically. The aim of this study was to compare the efficacy of a web-based computer-assisted education (CO-ED) system versus searching the Internet for learning about hypertension. Sixty hypertensive older adults (age 45+) were randomized into control or intervention groups. The control patients spent 30 to 40 minutes searching the Internet using a search engine for information about hypertension. The intervention patients spent 30 to 40 minutes using the CO-ED system, which provided computer-assisted instruction about major hypertension topics. Analysis of pre- and post- knowledge scores indicated a significant improvement among CO-ED users (14.6%) as opposed to Internet users (2%). Additionally, patients using the CO-ED program rated their learning experience more positively than those using the Internet.

    Many countries, including the United States, Canada, European Union member states, and others, require that a comprehensive search for possible alternatives be completed before beginning some or all research involving animals. Completing comprehensive alternatives searches and keeping current with information associated with alternatives to animal testing is a challenge that will be made easier as people throughout the world gain access to the Internet and World Wide Web. Numerous Internet and World Wide Web resources are available to provide guidance and other information on in vitro and other alternatives to animal testing. A comprehensive Web site is Alternatives to Animal Testing on the Web (Altweb), which serves as an online clearinghouse for resources, information, and news about alternatives to animal testing. Examples of other important Web sites include the joint one for the (US) Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) and the National Toxicology Program (NTP) Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) and the Norwegian Reference Centre for Laboratory Animal Science and Alternatives (The NORINA database). Internet mailing lists and online access to bulletin boards, discussion areas, newsletters, and journals are other ways to access and share information to stay current with alternatives to animal testing.

    The world wide web (WWW) has become a valuable source of 24 hour-a-day access to information needed by human health risk assessors. Various web sites and other Internet resources provide information needed for human hazard identification, dose-response evaluation, exposure assessment, risk characterization, and risk management. Information on risk communication is also available. Substantial collections of information on multiple aspects of risk assessment are found in sites sponsored by RiskWorld, the (US) EPA's National Center for Environmental Assessment (NCEA), the (US) National Library of Medicine's TOXNET, the (US) Agency for Toxic Substances and Disease Registry (ATSDR), and the International Programme on Chemical Safety (IPCS). Also valuable are various web sites providing information on the physical and chemical properties of chemicals, the environmental fate and transport of chemicals, government regulations, and guidance and training for performing risk assessments. Several professional societies and other organizations have web sites addressing risk assessment issues and information, and there are Internet mailing lists for online help and for sharing information and perspectives. We classify selected web sites according to user needs and provide the reader with a collection of selected sites that can serve as entry points to risk assessment-related web resources.

  10. Orthopaedic Web Links (OWL): a way to find professional orthopaedic information on the internet.

    Clough, J F M; Veillette, C J H

    2011-07-01

    Finding useful high-grade professional orthopaedic information on the Internet is often difficult. Orthopaedic Web Links (OWL) is a searchable database of vetted online orthopaedic resources. OWL uses a subject directory (OWL Directory) and a custom search engine (OWL Web) to provide a list of resources. The most effective way to find readily accessible, full text on-subject material suitable for education of an orthopaedic surgeon or trainee has not been defined. We therefore (1) proposed a method for selecting topics and evaluating searches and (2) compared the search results from an orthopaedic-specific directory (OWL Directory), a custom search engine (OWL Web), and standard Google searches. A scoring system for evaluation of the search results was developed for standardized comparison. Single words and sets of three words from randomly selected examination questions provided the search strings to compare the three strategies. For single keyword searches, the OWL Directory scored highest (16.4/50) of the three methods. For the three keywords searches, OWL Web had the highest mean score (26.0/50), followed by Google (22.8/50), and the OWL Directory (1.0/50). OWL Web searches had higher scores than Google searches, while returning 800 times fewer search results. The OWL Directory of orthopaedic subjects on the Internet provides a simple browsable category structure to find information. The OWL Web search engine scored higher than Google and resulted in a greater proportion of valid, on-subject, and accessible resources in the search results.

    A prototype has been developed which makes use of commercially available products in conjunction with the Java programming language to provide a secure user interface for command and control over the open Internet. This paper reports successful demonstration of: (1) Security over the Internet, including encryption and certification; (2) Integration of Java applets with a COTS command and control product; (3) Remote spacecraft commanding using the Internet. The Java-based Spacecraft Web Interface to Telemetry and Command Handling (Jswitch) ground system prototype provides these capabilities. This activity demonstrates the use and integration of current technologies to enable a spacecraft engineer or flight operator to monitor and control a spacecraft from a user interface communicating over the open Internet using standard World Wide Web (WWW) protocols and commercial off-the-shelf (COTS) products. The core command and control functions are provided by the COTS Epoch 2000 product. The standard WWW tools and browsers are used in conjunction with the Java programming technology. Security is provided with the current encryption and certification technology. This system prototype is a step in the direction of giving scientist and flight operators Web-based access to instrument, payload, and spacecraft data.

    Full Text Available It might be said that attitudes impact success directly in web-based teaching and timely and appropriate fulfillment of learners’ expectations bear utmost significance for their success. From this perspective a properly designed web supported teaching application can provide positive contribution as well to learners’ attitudes towards web supported teaching and internet. Based on this premise, the objective of present research is to explore the effects of different interaction types in web-based teaching setting on the attitudes of learners towards web-based teaching and internet. An experimental pattern with pretest-posttest control group was used in the study. Study group of research consists of 77 students. Research data have been compiled via Attitude towards Internet Scale (α=0,77 and Attitude towards Web-based Learning Scale (α=0,86. In one of the experimental groups, synchronous web-based training interaction and in the other group asynchronous web-based training interaction and in the control group learner-content only interaction has been provided. In data analysis; standard deviation, arithmetical means, one-way variance analysis and LSD tests have been employed. As a result: Web-based training applications with synchronous interaction, compared to web-based training application with learner-content only interaction, have significantly higher contribution on learners’ attitudes towards web-based teaching. In Web-based teaching settings different types of interaction have no effect on learners’ attitudes towards internet which may be attributed to the fact that learners’ attitudes towards internet were already in quite high levels prior to the procedure.

    Web-based education through archived educational modules offers a significant opportunity to provide didactic education. By archiving lectures and teaching materials, it reduces the educators' time of preparation, especially when many students will need to take the same curriculum over a long period of time. The site can package educational material in multiple formats including audio, video, and readable text, allowing the student to tailor the educational experience to his/her learning preferences. This can be a stand-alone program, or integrated into a program combining distance and in-person education. Assessment through on-line tests can also be conducted, but these must be considered open-book assessments where collaboration cannot be prevented. As such, this vehicle can be utilized effectively for continuing education programs in health care, where open book is permitted and credits are generally awarded on the honor system. However, tests for certificate courses should only be given with a proctor in attendance. In this instance, on-line tests can be used as pre-tests for the student, while being structured to enhance further learning.

    Full Text Available In the previous report in this series, Web browser loading times were measured in 12 Asian countries, and were found to be up to four times slower than commonly prescribed as acceptable. Failure of webpages to load at all was frequent. The current follow-up study compares these loading times with the complexity of the Internet routes linking the Web users and the Web servers hosting them. The study was conducted in the same 12 Asian countries, with the assistance of members of the International Development Research Centre’s PANdora distance education research network. The data were generated by network members in Bhutan, Cambodia, India, Indonesia, Laos, Mongolia, the Philippines, Sri Lanka, Pakistan, Singapore, Thailand, and Vietnam. Additional data for the follow-up study were collected in China. Using a ‘traceroute’ routine, the study indicates that webpage loading time is linked to the complexity of the Internet routes between Web users and the host server. It is indicated that distance educators can apply such information in the design of improved online delivery and mirror sites, notably in areas of the developing world which currently lack an effective infrastructure for online education.

    This paper outlines the grand challenges in global sustainability research and the objectives of the FP7 Future Internet PPP program within the Digital Agenda for Europe. Large user communities are generating significant amounts of valuable environmental observations at local and regional scales using the devices and services of the Future Internet. These communities’ environmental observations represent a wealth of information which is currently hardly used or used only in isolation and therefore in need of integration with other information sources. Indeed, this very integration will lead to a paradigm shift from a mere Sensor Web to an Observation Web with semantically enriched content emanating from sensors, environmental simulations and citizens. The paper also describes the research challenges to realize the Observation Web and the associated environmental enablers for the Future Internet. Such an environmental enabler could for instance be an electronic sensing device, a web-service application, or even a social networking group affording or facilitating the capability of the Future Internet applications to consume, produce, and use environmental observations in cross-domain applications. The term “envirofied” Future Internet is coined to describe this overall target that forms a cornerstone of work in the Environmental Usage Area within the Future Internet PPP program. Relevant trends described in the paper are the usage of ubiquitous sensors (anywhere), the provision and generation of information by citizens, and the convergence of real and virtual realities to convey understanding of environmental observations. The paper addresses the technical challenges in the Environmental Usage Area and the need for designing multi-style service oriented architecture. Key topics are the mapping of requirements to capabilities, providing scalability and robustness with implementing context aware information retrieval. Another essential research topic is handling

    Huang, Chih-Yuan; Wu, Cheng-Hung

    2016-01-01

    The Internet of Things (IoT) is an infrastructure that interconnects uniquely-identifiable devices using the Internet. By interconnecting everyday appliances, various monitoring, and physical mashup applications can be constructed to improve human’s daily life. In general, IoT devices provide two main capabilities: sensing and tasking capabilities. While the sensing capability is similar to the World-Wide Sensor Web, this research focuses on the tasking capability. However, currently, IoT devices created by different manufacturers follow different proprietary protocols and are locked in many closed ecosystems. This heterogeneity issue impedes the interconnection between IoT devices and damages the potential of the IoT. To address this issue, this research aims at proposing an interoperable solution called tasking capability description that allows users to control different IoT devices using a uniform web service interface. This paper demonstrates the contribution of the proposed solution by interconnecting different IoT devices for different applications. In addition, the proposed solution is integrated with the OGC SensorThings API standard, which is a Web service standard defined for the IoT sensing capability. Consequently, the Extended SensorThings API can realize both IoT sensing and tasking capabilities in an integrated and interoperable manner. PMID:27589759

  5. Embedded Web Technology: Internet Technology Applied to Real-Time System Control

    1998-01-01

    The NASA Lewis Research Center is developing software tools to bridge the gap between the traditionally non-real-time Internet technology and the real-time, embedded-controls environment for space applications. Internet technology has been expanding at a phenomenal rate. The simple World Wide Web browsers (such as earlier versions of Netscape, Mosaic, and Internet Explorer) that resided on personal computers just a few years ago only enabled users to log into and view a remote computer site. With current browsers, users not only view but also interact with remote sites. In addition, the technology now supports numerous computer platforms (PC's, MAC's, and Unix platforms), thereby providing platform independence.In contrast, the development of software to interact with a microprocessor (embedded controller) that is used to monitor and control a space experiment has generally been a unique development effort. For each experiment, a specific graphical user interface (GUI) has been developed. This procedure works well for a single-user environment. However, the interface for the International Space Station (ISS) Fluids and Combustion Facility will have to enable scientists throughout the world and astronauts onboard the ISS, using different computer platforms, to interact with their experiments in the Fluids and Combustion Facility. Developing a specific GUI for all these users would be cost prohibitive. An innovative solution to this requirement, developed at Lewis, is to use Internet technology, where the general problem of platform independence has already been partially solved, and to leverage this expanding technology as new products are developed. This approach led to the development of the Embedded Web Technology (EWT) program at Lewis, which has the potential to significantly reduce software development costs for both flight and ground software.

    The Internet has been transformed in the past years from a system primarily oriented on information provision into a medium for communication and community-building. The notion of "Web 2.0", social software, and social networking sites such as Facebook, Twitter and MySpace have emerged in this context. With such platforms comes the massive provision and storage of personal data that are systematically evaluated, marketed, and used for targeting users with advertising. In a world of global economic competition, economic crisis, and fear of terrorism after 9/11, both corporations and state insti

    We present here the most modern internet and web technologies which we have tested and verified to be very suitable for the development of innovative, web-based tools for observational astronomy and archival data exploitation. Nothing but an updated browser is required to the user. This approach can boost the exploitation of huge data archives such as those that will be produced by projects like GAIA and TAOS-II, and will allow to easily manage heterogeneous data, like those of the IPERCOOL project. In spite these technologies are still not fully mature, they are already accepted standards in the browsers of our laptops, tablets and cellphones. We discuss the impact of these new technologies in astronomy and present test examples to show their capabilities.

    Students seek active learning experiences that can rapidly impart relevant information in the most convenient way possible. Computer-assisted education can now use the resources of the World Wide Web to convey the important characteristics of events as elemental as the physical properties of osmotically active particles in the cell and as complex as the nerve action potential or the integrative behavior of the intact organism. We have designed laboratory exercises that introduce first-year medical students to membrane and action potentials, as well as the more complex example of integrative physiology, using the dynamic properties of computer simulations. Two specific examples are presented. The first presents the physical laws that apply to osmotic, chemical, and electrical gradients, leading to the development of the concept of membrane potentials; this module concludes with the simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module simulates the action potential according to the Hodgkin-Huxley model, illustrating the concepts of threshold, inactivation, refractory period, and accommodation. Students can access these resources during the scheduled laboratories or on their own time via our Web site on the Internet (http./(/)phys-main.umsmed.edu) by using the World Wide Web protocol. Accurate version control is possible because one valid, but easily edited, copy of the labs exists at the Web site. A common graphical interface is possible through the use of the Hypertext mark-up language. Platform independence is possible through the logical and arithmetic calculations inherent to graphical browsers and the Javascript computer language. The initial success of this program indicates that medical education can be very effective both by the use of accurate simulations and by the existence of a universally accessible Internet resource.

    Urban sprawl and the corresponding land use change from lower intensity uses, such as agriculture and forests, to higher intensity uses including high density residential and commercial has various long- and short-term environment impacts on ground water recharge, water pollution, and storm water drainage. A web-based Spatial Decision Support System, SDSS, for Web-based operation of long-term hydrologic impact modeling and analysis was developed. The system combines a hydrologic model, databases, web-GIS capability and HTML user interfaces to create a comprehensive hydrologic analysis system. The hydrologic model estimates daily direct runoff using the NRCS Curve Number technique and annual nonpoint source pollution loading by an event mean concentration approach. This is supported by a rainfall database with over 30 years of daily rainfall for the continental US. A web-GIS interface and a robust Web-based watershed delineation capability were developed to simplify the spatial data preparation task that is often a barrier to hydrologic model operation. The web-GIS supports browsing of map layers including hydrologic soil groups, roads, counties, streams, lakes and railroads, as well as on-line watershed delineation for any geographic point the user selects with a simple mouse click. The watershed delineation results can also be used to generate data for the hydrologic and water quality models available in the DSS. This system is already being used by city and local government planners for hydrologic impact evaluation of land use change from urbanization, and can be found at http://pasture.ecn.purdue.edu/~watergen/hymaps. This system can assist local community, city and watershed planners, and even professionals when they are examining impacts of land use change on water resources. They can estimate the hydrologic impact of possible land use changes using this system with readily available data supported through the Internet. This system provides a cost effective

    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.

    Full Text Available Abstract Background Internet social networking tools and the emerging web 2.0 technologies are providing a new way for web users and health workers in information sharing and knowledge dissemination. Based on the characters of immediate, two-way and large scale of impact, the internet social networking tools have been utilized as a solution in emergency response during disasters. This paper highlights the use of internet social networking in disaster emergency response and public health management of disasters by focusing on a case study of the typhoon Morakot disaster in Taiwan. Discussion In the case of typhoon disaster in Taiwan, internet social networking and mobile technology were found to be helpful for community residents, professional emergency rescuers, and government agencies in gathering and disseminating real-time information, regarding volunteer recruitment and relief supplies allocation. We noted that if internet tools are to be integrated in the development of emergency response system, the accessibility, accuracy, validity, feasibility, privacy and the scalability of itself should be carefully considered especially in the effort of applying it in resource poor settings. Summary This paper seeks to promote an internet-based emergency response system by integrating internet social networking and information communication technology into central government disaster management system. Web-based networking provides two-way communication which establishes a reliable and accessible tunnel for proximal and distal users in disaster preparedness and management.

    The World Wide Web (WWW) poses a distinct capability to offer interventions tailored to the individual's characteristics. To fine tune the tailoring process, studies are needed to explore how Internet accessibility and usage are related to demographic, psychosocial, behavioral, and other health related characteristics. This study was based on a cross-sectional survey conducted on 2373 7th grade students of various ethnic groups in Southern California. Measures of Internet use included Internet use at school or at home, Email use, chat-room use, and Internet favoring. Logistic regressions were conducted to assess the associations between Internet uses with selected demographic, psychosocial, behavioral variables and self-reported health statuses. The proportion of students who could access the Internet at school or home was 90% and 40%, separately. Nearly all (99%) of the respondents could access the Internet either at school or at home. Higher SES and Asian ethnicity were associated with higher internet use. Among those who could access the Internet and after adjusting for the selected demographic and psychosocial variables, depression was positively related with chat-room use and using the Internet longer than 1 hour per day at home, and hostility was positively related with Internet favoring (All ORs = 1.2 for +1 STD, p 4.0, p < 0.05). Self-reported health problems were associated with higher levels of Internet use at home but lower levels of Internet use at school.

    Social computing technologies are transforming the way our society interacts and generates content on the Web via collective intelligence. Previously unimagined possibilities have arisen for using these technologies to engage stakeholders and involve them in policy making and planning efforts. While the Internet has been used in the past to support education and communication endeavors, we have developed a novel, web-based, interactive planning tool that engages the community in using science-based methods for the design of potential conservation practices on their landscape, and thereby, reducing undesirable impacts of extreme hydroclimatic events. The tool, Watershed REstoration using Spatio-Temporal Optimization of Resources (WRESTORE), uses a democratic voting process coupled with visualization interfaces, computational simulation and optimization models, and user modeling techniques to support a human-centered design approach. This human-centered design approach, which is reinforced by use of Web 2.0 technologies, has the potential to enable policy makers to connect to a larger community of stakeholders and directly engage them in environmental stewardship efforts. Additionally, the design framework can be used by watershed groups to plug-in their own hydrologic models, climate observations and forecasts, and various other simulation models unique to their watersheds. In this presentation, we will demonstrate the effectiveness of WRESTORE for designing alternatives of conservation practices in a HUC-11 Midwestern watershed, results of various experiments with a diverse set of test users and stakeholders, and discuss potential for future developments.

A saturação teórica do estudo foi obtida por meio do questionário aplicado à equipe de duas bibliotecas americanas que utilizam o Del.icio.us para desenvolver seus guias de literatura. Os dados coletados revelam que no Connotea é mais fácil localizar a informação do que no Citeulike. Os campos disponibilizados para a descrição de documentos no Connotea não são adequados para um guia de literatura na web, já os campos do Citeulike são considerados adequados. Os participantes da pesquisa utilizariam o Citeulike para desenvolver um guia de literatura na web, mas não utilizariam o Connotea. As bibliotecas americanas, apesar de terem pesquisado sobre o Connotea e o Citeulike preferiram utilizar o Del.icio.us para disponibilizar seus guias. Dentre os motivos houve destaque para a estabilidade e número de usuários da plataforma.

    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.

    Full Text Available Hatte man in den Neunzigerjahren das Netz vor allem als virtuelle Realität charakterisiert, das dem realen Alltag gegenübersteht, so wird immer stärker deutlich, wie stark die Kultur der alltäglichen Lebenswelt mit dem Kulturraum Internet verflochten ist. So wird das Netz, wo man online einkauft, Freunde im Chat trifft, sich täglich über aktuelle Nachrichten informiert, immer mehr als Erweiterung des alltäglichen Lebens betrachtet. Dies bedeutet daher auch, dass wer am Netz aktiv partizipiert, zugleich über einen Anteil an gesellschaftlicher Macht verfügt. Politische Kampagnen im Internet oder die Präsentation von Politikern/-innen bei Wahlkämpfen im Netz unterstreichen diesen Trend auf eindrückliche Weise. Damit ist das Internet ist in den letzten Jahren zu einem Kulturraum sui generis avanciert. Zuerst war das Netz vor allem ein vom Sender gesteuertes «Push-Medium», von welchem Informationen rezipiert und heruntergeladen wurden. Nicht jede/r konnte die Funktion des Senders einnehmen.

    Hypothermia is a medical condition characterized by a drop in core body temperature, and it is a considerable source of winter weather-related vulnerability in mid-/high-latitude areas. Heat vulnerability research, including assessments of internet-based resources, is more thoroughly represented in the peer-reviewed literature than cold-related vulnerability research. This study was undertaken to summarize available web-based hypothermia information, and then determine its scientific validity compared to the peer-reviewed literature. This research takes a similar approach used by Hajat et al. for web-based heat vulnerability research, and utilizes this framework to assess hypothermia information found on the internet. Hypothermia-related search terms were used to obtain websites containing hypothermia information, and PubMed (medical literature search engine) and Google Scholar were used to identify peer-reviewed hypothermia literature. The internet information was aggregated into categories (vulnerable populations, symptoms, prevention), which were then compared to the hypothermia literature to determine the scientific validity of the web-based guidance. The internet information was assigned a Strength of Recommendation Taxonomy (SORT) grade (developed by the American Academy of Family Practitioners) of A, B, or C based on the peer-reviewed evidence. Overall, 25 different pieces of guidance within the three categories were identified on 49 websites. Guidance concerning hypothermia symptoms most frequently appeared on websites, with six symptoms appearing on 50% or greater of websites. No piece of guidance within the vulnerable population categories appeared on greater than 60% of the websites, and prevention-related guidance was characterized by varied SORT grades. Hypothermia information on the internet was not entirely congruent with the information within the peer-reviewed medical literature. Several suggestions for improving web-based hypothermia resources

    Parents of children with rare conditions increasingly use the Internet to source information on their child's condition. This study reports on part of a larger study whose overall aim was to identify the Internet use by parents when seeking information on their child's rare condition, with the specific purpose of using the findings to aid in the development of a website specifically designed to meet the parents' needs. It presents findings on why these parents use the Internet, the information and support content they source, and the impact these resources have on their capacity to care for and manage their child's condition. To (1) ascertain parents' general Internet usage patterns, (2) identify the nature of the information parents most frequently searched for, and (3) determine the effect the Internet-sourced information had on parents of children with rare conditions. Data collection was conducted in 2 parts: Part 1 was a focus group interview (n=8) to inform the development of the questionnaire, and Part 2 was a questionnaire (Web- and paper-based). All respondents (N=128) completed the questionnaire using the Internet. Parents frequently and habitually used the Internet and social media to gather information on their child's condition. These Web-based resources provide parents with a parent-to-parent support platform that allows them to share their experiences and information with other parents, which, the respondents considered, improved their knowledge and understanding of their child's condition. The respondents also reported that these resources positively impacted on their decision making, care, and management of their child's condition. However, they reported receiving mixed responses when wishing to engage and share with health care professionals their Internet and social media interactions and information outcomes. This study adds to the emerging body of research on the Internet use by parents of children with rare conditions to source information on

    2007-11-01

    The use of Web (i.e. Internet)-derived health information within the health care encounter is rapidly increasing. In this article, an extensive review of the complex effects and sometimes contradictory roles of the Web in regard to health care delivery and the physician-patient relationship is presented. A review of relevant literature was conducted, with key points integrated into a physician guide for effective interaction with Web-activated patients. An emerging consumerist model with "triangulation" of patient-Web-physician can be expected to significantly impact dynamics of the physician-patient relationship. Potential advantages of Web-acquired information include helping patients make informed health care choices (with potential to decrease health care disparities), shared decision-making with a collaborative, teamwork approach, more efficient use of clinical time, augmenting of physician-provided information, online support groups, and/or access to patients' own health information. Alternatively, factors such as misinformation due to highly variable quality of Web information, possible exacerbation of socioeconomic health disparities, and shifting of conventional notions of the physician-patient relationship ("traditional" medical authority) present their own set of challenges for the health care provider. A tangible guide to the integration of patients' use of the Web within a medical practice is thus offered with recommended communication skills. The "net-friendly" clinician can be effective by engendering a genuine partnership with patients, thus contributing to quality health care.

    Many scientists use quantitative measurements to compare the presence and amount, of various proteins and nucleotides among series of one- and two-dimensional (1-D and 2-D) electrophoretic gels. These gels are often scanned into digital image files. Gel spots are then quantified using stand-alone analysis software. However, as more research collaborations take place over the Internet, it has become useful to share intermediate quantitative data between researchers. This allows research group members to investigate their data and share their work in progress. We developed a World Wide Web group-accessible software system, WebGel, for interactively exploring qualitative and quantitative differences between electrophoretic gels. Such Internet databases are useful for publishing quantitative data and allow other researchers to explore the data with respect to their own research. Because intermediate results of one user may be shared with their collaborators using WebGel, this form of active data-sharing constitutes a groupware method for enhancing collaborative research. Quantitative and image gel data from a stand-alone gel image processing system are copied to a database accessible on the WebGel Web server. These data are then available for analysis by the WebGel database program residing on that server. Visualization is critical for better understanding of the data. WebGel helps organize labeled gel images into montages of corresponding spots as seen in these different gels. Various views of multiple gel images, including sets of spots, normalization spots, labeled spots, segmented gels, etc. may also be displayed. These displays are active and may be used for performing database operations directly on individual protein spots by simply clicking on them. Corresponding regions between sets of gels may be visually analyzed using Flicker-comparison (Electrophoresis 1997, 18, 122-140) as one of the WebGel methods for qualitative analysis.

    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.

As a within-participants factor, each participant browsed both a standardized English-language Web site and a localized Web site. Results showed that animated (rather than static) banner ads, localized versions (rather than a standardized version) of Web sites, and high (rather than low) product involvement led to favorable attitudes toward the site.

    The acceptability and clinical impact of a web-based intervention among patients entering addiction treatment who lack recent internet access are unclear. This secondary analysis of a national multisite treatment study (NIDA Clinical Trials Network-0044) assessed for acceptability and clinical impact of a web-based psychosocial intervention among participants enrolling in community-based, outpatient addiction treatment programs. Participants were randomly assigned to 12 weeks of a web-based therapeutic education system (TES) based on the community reinforcement approach plus contingency management versus treatment as usual (TAU). Demographic and clinical characteristics, and treatment outcomes were compared among participants with recent internet access in the 90 days preceding enrollment (N = 374) and without internet access (N = 133). Primary outcome variables included (1) acceptability of TES (i.e., module completion; acceptability of web-based intervention) and (2) clinical impact (i.e., self-reported abstinence confirmed by urine drug/breath alcohol tests; retention measured as time to dropout). Internet use was common (74 %) and was more likely among younger (18-49 years old) participants and those who completed high school (p < .001). Participants randomized to TES (n = 255) without baseline internet access rated the acceptability of TES modules significantly higher than those with internet access (t = 2.49, df = 218, p = .01). There was a near significant interaction between treatment, baseline abstinence, and internet access on time to dropout (χ 2 (1) = 3.8089, p = .051). TES was associated with better retention among participants not abstinent at baseline who had internet access (X 2 (1) = 6.69, p = .01). These findings demonstrate high acceptability of this web-based intervention among participants that lacked recent internet access.

    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.

    In 1998 the Swedish noncommercial public health service Infomedica opened an Ask the Doctor service on its Internet portal. At no charge, anyone with Internet access can use this service to ask questions about personal health-related and disease-related matters. To study why individuals choose to consult previously-unknown doctors on the Internet. Between November 1, 2001, and January 31, 2002 a Web survey of the 3622 Ask the Doctor service users, 1036 men (29%) and 2586 (71%) women, was conducted. We excluded 186 queries from users. The results are based on quantitative and qualitative analysis of the answers to the question "Why did you choose to ask a question at Infomedica's 'Ask the Doctor' service?" 1223 surveys were completed (response rate 36 %). Of the participants in the survey 322 (26%) were male and 901 (74%) female. As major reasons for choosing to consult previously-unknown doctors on the Internet participants indicated: convenience (52%), anonymity (36%), "doctors too busy" (21%), difficult to find time to visit a doctor (16%), difficulty to get an appointment (13%), feeling uncomfortable when seeing a doctor (9%), and not being able to afford a doctors' visit (3%). Further motives elicited through a qualitative analysis of free-text answers were: seeking a second opinion, discontent with previous doctors and a wish for a primary evaluation of a medical problem, asking embarrassing or sensitive questions, seeking information on behalf of relatives, preferring written communication, and (from responses by expatriates, travelers, and others) living far away from regular health care. We found that that an Internet based Ask the Doctor service is primarily consulted because it is convenient, but it may also be of value for individuals with needs that regular health care services have not been able to meet.

    User-centric service features in a Web of Object-enabled Internet of Things environment can be provided by using a semantic ontology that classifies and integrates objects on the World Wide Web as well as shares and merges context-aware information and accumulated knowledge. The semantic ontology is applied on a Web of Object platform to virtualize the real world physical devices and information to form virtual objects that represent the features and capabilities of devices in the virtual world. Detailed information and functionalities of multiple virtual objects are combined with service rules to form composite virtual objects that offer context-aware knowledge-based services, where context awareness plays an important role in enabling automatic modification of the system to reconfigure the services based on the context. Converting the raw data into meaningful information and connecting the information to form the knowledge and storing and reusing the objects in the knowledge base can both be expressed by semantic ontology. In this paper, a knowledge creation model that synchronizes a service logistic model and a virtual world knowledge model on a Web of Object platform has been proposed. To realize the context-aware knowledge-based service creation and execution, a conceptual semantic ontology model has been developed and a prototype has been implemented for a use case scenario of emergency service.

    Full Text Available Recent advancements in the Internet of Things (IoT and the Web of Things (WoT accompany a smart life where real world objects, including sensing devices, are interconnected with each other. The Web representation of smart objects empowers innovative applications and services for various domains. To accelerate this approach, Web of Objects (WoO focuses on the implementation aspects of bringing the assorted real world objects to the Web applications. In this paper; we propose an emergency fire management system in the WoO infrastructure. Consequently, we integrate the formation and management of Virtual Objects (ViO which are derived from real world physical objects and are virtually connected with each other into the semantic ontology model. The charm of using the semantic ontology is that it allows information reusability, extensibility and interoperability, which enable ViOs to uphold orchestration, federation, collaboration and harmonization. Our system is context aware, as it receives contextual environmental information from distributed sensors and detects emergency situations. To handle a fire emergency, we present a decision support tool for the emergency fire management team. The previous fire incident log is the basis of the decision support system. A log repository collects all the emergency fire incident logs from ViOs and stores them in a repository.

    Adolescents and young adults are among the most frequent Internet users, and accumulating evidence suggests that their Internet behaviors might affect their mental health. Internet use may impact mental health because certain Web-based content could be distressing. It is also possible that excessive use, regardless of content, produces negative consequences, such as neglect of protective offline activities. The objective of this study was to assess how mental health is associated with (1) the time spent on the Internet, (2) the time spent on different Web-based activities (social media use, gaming, gambling, pornography use, school work, newsreading, and targeted information searches), and (3) the perceived consequences of engaging in those activities. A random sample of 2286 adolescents was recruited from state schools in Estonia, Hungary, Italy, Lithuania, Spain, Sweden, and the United Kingdom. Questionnaire data comprising Internet behaviors and mental health variables were collected and analyzed cross-sectionally and were followed up after 4 months. Cross-sectionally, both the time spent on the Internet and the relative time spent on various activities predicted mental health (Pgaming, gambling, and targeted searches had mental health effects that were not fully accounted for by perceived consequences. The longitudinal analyses showed that sleep loss due to Internet use (ß=.12, 95% CI=0.05-0.19, P=.001) and withdrawal (negative mood) when Internet could not be accessed (ß=.09, 95% CI=0.03-0.16, Peffect on mental health in the long term. Perceived positive consequences of Internet use did not seem to be associated with mental health at all. The magnitude of Internet use is negatively associated with mental health in general, but specific Web-based activities differ in how consistently, how much, and in what direction they affect mental health. Consequences of Internet use (especially sleep loss and withdrawal when Internet cannot be accessed) seem to predict

    There are multiple ways in which community pharmacies can present themselves on the Internet, e.g., as a platform for drug information or as an advertising platform for their services. To estimate the number of Swiss community pharmacies on the Internet over the period of 32 months (2000-2003), to describe their current e-commerce services, and to explore the experiences and plans these pharmacies have with regard to their Internet presence. A longitudinal study was performed to determine the number of Swiss German pharmacies on the Internet by conducting Internet searches in 2000, 2001, and 2003. In April 2002, a cross-sectional Internet-based survey was administered to explore the pharmacies' experiences and plans regarding their Web sites. As of April 2003, 373 (44%) of 852 community pharmacies from the German speaking part of Switzerland were on the Internet. One hundred eighty four listed an e-mail address and were asked to complete a questionnaire. Of the 107 pharmacies answering the survey questions (58% response rate): 46% had been on the Internet for 1 to 2 years; 33% of the Web sites are part of a pharmacy group's Web portal; 31% of the pharmacies plan to expand their Internet appearance in the future; 74% provide e-commerce services, with 81% of those pharmacies filling five or less orders per month; and 12% plan on expanding their e-commerce services in the future. The number of community pharmacies offering Internet services steadily increased over 32 months. Given the importance of the Internet as a tool for information, communication, and advertising for pharmacy products and services, it can be expected that the increase will continue. Pharmacy-group portals are important promoters of pharmacies on the Internet. For many community pharmacies, Internet portals that provide an Internet presence for the pharmacies and provide regularly-updated content (e.g., health news, tips, drug information) seem to be the most effective solutions.

    Background There are multiple ways in which community pharmacies can present themselves on the Internet, e.g., as a platform for drug information or as an advertising platform for their services. Objective To estimate the number of Swiss community pharmacies on the Internet over the period of 32 months (2000-2003), to describe their current e-commerce services, and to explore the experiences and plans these pharmacies have with regard to their Internet presence. Methods A longitudinal study was performed to determine the number of Swiss German pharmacies on the Internet by conducting Internet searches in 2000, 2001, and 2003. In April 2002, a cross-sectional Internet-based survey was administered to explore the pharmacies' experiences and plans regarding their Web sites. Results As of April 2003, 373 (44%) of 852 community pharmacies from the German speaking part of Switzerland were on the Internet. One hundred eighty four listed an e-mail address and were asked to complete a questionnaire. Of the 107 pharmacies answering the survey questions (58% response rate): 46% had been on the Internet for 1 to 2 years; 33% of the Web sites are part of a pharmacy group's Web portal; 31% of the pharmacies plan to expand their Internet appearance in the future; 74% provide e-commerce services, with 81% of those pharmacies filling five or less orders per month; and 12% plan on expanding their e-commerce services in the future. Conclusions The number of community pharmacies offering Internet services steadily increased over 32 months. Given the importance of the Internet as a tool for information, communication, and advertising for pharmacy products and services, it can be expected that the increase will continue. Pharmacy-group portals are important promoters of pharmacies on the Internet. For many community pharmacies, Internet portals that provide an Internet presence for the pharmacies and provide regularly-updated content (e.g., health news, tips, drug information) seem to

    Full Text Available Neste artigo investigamos as oportunidades que a internet favorece para grupos minoritários e marginalizados expressarem-se. Voltamos nossa atenção para a luta pelo reconhecimento empreendida por pessoas surdas e em particular para a representação política das lideranças do movimento social dos surdos e para as contestações em torno das definições de "bem comum" reveladas pelos membros dessa coletividade. Tomamos como material de análise os testemunhos de vida expressos em dois ambientes virtuais diferentes na Internet: o sítio eletrônico de uma associação de surdos - a Federação Nacional de Educação e Integração dos Surdos (Feneis - e um fórum de discussão de uma rede virtual de relacionamentos (o Orkut. Os testemunhos do sítio da Feneis revelam um discurso público relativamente homogêneo - com definições de bem viver e projeções de metas futuras - que busca demonstrar a existência de um "nós", mediar a formação da opinião e expressar a vontade política. Já a análise do fórum do Orkut mostra que afetados e concernidos, ao discutirem sobre suas aspirações individuais e seus interesses, produzem grande fragmentação sobre detalhes do bem comum. Argumentamos que o uso do testemunho produz diferentes efeitos no que concerne ao intercâmbio de experiências, à defesa da legitimidade das reivindicações e à aprendizagem coletiva, em diferentes ambientes virtuais.

    Full Text Available Conforme Bakhtin, as poéticas de Rabelais e de Dostoiévski descendem diretamente de uma literatura folclórica tradicionalmente oral e popular intimamente ligada aos festejos e ritos carnavalescos, refletindo, mais que aspectos estético-estilísticos, aspectos culturais. Nesse contexto, o objetivo deste artigo é aplicar o conceito de carnavalização (BAKHTIN, 2005, 2010a; 2010b a práticas textual-discursivas produzidas para além do âmbito literário e disseminadas na web, mais especificamente em sites de humor, blogs e wikis. Verificamos que as categorias relativas à carnavalização, a saber, atualidade, subversão, paródia e polifonia são produtivas para um melhor entendimento de textos produzidos na web. Os resultados a que chegamos apontam que aspectos da cultura popular encontram-se consolidados no inconsciente social – algo verificável tanto por parte dos produtores dos textos carnavalizados quanto por parte dos difusores de tais textos, os quais se aproveitam do caráter colaborativo da web 2.0 para disseminar e perpetuar a cultura cômica popular.

    Background and aims People with substance abuse and pathological gamblers show an attentional bias. In a laboratory setting, we found an attentional bias using an addiction Stroop in adults with Internet Gaming Disorder (IGD). We aimed at investigating this effect using two web-based experiments. Methods Study 1: Gamers with IGD, casual gamers, and non-gamers (N = 81, 28.1 ± 7.8 years) completed a web-based addiction Stroop with a fully randomized word order. They saw computer-related and neutral words in four colors and indicated the word color via keypress. Study 2: Gamers with IGD, casual gamers, and non-gamers (N = 87, 23.4 ± 5.1 years) completed a web-based addiction Stroop and a classical Stroop (incongruent color and neutral words), which both had a block design. We expected that in both studies, only the gamers with IGD would react more slowly to computer-related words in the addiction Stroop. All groups were expected to react more slowly to incongruent color words in the classical Stroop. Results In neither study did the gamers with IGD differ in their reaction times to computer-related words compared to neutral words. In Study 2, all groups reacted more slowly to incongruent color words than to neutral words confirming the validity of the online reaction time assessment. Discussion Gamers with IGD did not show a significant attentional bias. IGD may differ from substance abuse and pathological gambling in this respect; alternatively experimenting on the Internet may have introduced error variance that made it harder to detect a bias.

    Background The internet is a huge library with avalanche of information resources including healthcare information. There are numerous studies on use of electronic resources by healthcare providers including medical practitioners however, there is a dearth of information on the patterns of use of web-based health information resource by resident doctors in Nigeria. This study therefore investigates the influence of internet accessibility and demographic factors on utilization of web-based health information resources by resident doctors in tertiary healthcare institutions in Nigeria. Methods Descriptive survey design was adopted for this study. The population of study consisted of medical doctors undergoing residency training in 13 tertiary healthcare institutions in South-West Nigeria. The tertiary healthcare institutions were Federal Medical Centres, University Teaching Hospitals and Specialist Hospitals (Neuropsychiatric and Orthopaedic). A pre-tested, self-administered questionnaire was used for data collection. The Statistical Package for the Social Sciences (SPSS) was used for data analysis. Data were analyzed using descriptive statistics, Pearson Product Moment correlation and multiple regression analysis. Results The mean age of the respondents was 34 years and males were in the majority (69.0%). A total of 96.1% respondents had access to the Internet. E-mail (X̄=5.40, SD=0.91), Google (X̄=5.26, SD=1.38), Yahoo (X̄=5.15, SD=4.44) were used weekly by the respondents. Preparation for Seminar/Grand Round presentation (X̄=8.4, SD=1.92), research (X̄=7.8, SD=2.70) and communication (X̄=7.6, SD=2.60) were ranked high as purposes for use of web-based information resources. There is a strong, positive and significant relationship between internet accessibility and utilization of web-based health information resources (r=0.628, pInternet accessibility (B=0.911) and demographic factors: gender (B=−2.027), designation (B=−0.343) educational qualification (B

    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.

    Given the potential advantages of online assessment of implicit alcohol-related cognitive processes, the goal of this study was to empirically validate the online administration of the implicit association test (IAT). First, we examined whether an Internet-delivered IAT programmed in Flash can be as effectively used to assess implicit alcohol-related associations as equivalent IAT versions that are programmed in local lab software, such as Inquisit. Second, participants performed the IAT versions once in the controlled laboratory setting and once on their home computers via the Internet. Findings with the alcohol IAT versions were robust and did not vary systematically with respect to setting (home or lab) or assessment software (Flash or Inquisit). Importantly, there were also indications that IAT versions performed at home were more strongly related to explicit measures and drinking behavior than were lab-based IAT versions. Together, these findings demonstrate that the alcohol IAT can be validly administered online via participants' home computers.

    Full Text Available Internet addiction (IA has become a widespread and problematic phenomenon as smart devices pervade society. Moreover, internet gaming disorder leads to increases in social expenditures for both individuals and nations alike. Although the prevention and treatment of IA are getting more important, the diagnosis of IA remains problematic. Understanding the neurobiological mechanism of behavioral addictions is essential for the development of specific and effective treatments. Although there are many databases related to other addictions, a database for IA has not been developed yet. In addition, bioinformatics databases, especially genetic databases, require a high level of security and should be designed based on medical information standards. In this respect, our study proposes the OAuth standard protocol for database access authorization. The proposed IA Bioinformatics (IABio database system is based on internet user authentication, which is a guideline for medical information standards, and uses OAuth 2.0 for access control technology. This study designed and developed the system requirements and configuration. The OAuth 2.0 protocol is expected to establish the security of personal medical information and be applied to genomic research on IA.

    Full Text Available : The internet at the periphery: between potential and concrete use — This article makes a critique of advertising and academic discourse that see in the internet a tool for the generalized expansion of the human potential. Based on a cleavage between a merely technical approach and the concrete and socially determined use of the net, an attempt is made to demonstrate the existence of external conditioning factors that hinder the emancipatory meaningful use of computer-mediated communication. This demonstration is based on an empirical study of adolescent frequenters of lan houses in the periphery of São Paulo, where the internet emerges almost exclusively as a form of light entertainment and as a reinforcement of preexisting social bonds, in contrast to the utopian ideas of knowledge expansion and of the construction of a "collective intelligence" that permeate the exalted imagination about the current technology. Este artigo dedica-se a criticar os discursos publicitários e parte do pensamento acadêmico que veem na internet uma ferramenta para a ampliação generalizada do potencial humano. A partir de uma clivagem entre uma abordagem meramente técnica e o uso concreto e so- cialmente determinado da rede, procura-se demonstrar a vigência de condicionantes externas que relativizam ou impedem um uso provido de sentido emancipatório da comunicação informática. Essa demonstração é calcada em estudo empírico realizado entre adolescentes usuários de lan houses na periferia de São Paulo, onde a internet surge quase exclusiva- mente como forma de entretenimento leve e como reforço de laços sociais pré-existentes, em contraposição às utopias de ampliação do conhecimento e construção de "inteligências coletivas" que permeiam o imaginário de exaltação da tecnológica vigente.

    The internet is an ideal forum for tobacco marketing, as it is largely unregulated and there is no global governing body for controlling content. Nevertheless, tobacco companies deny advertising on the internet. To assess the extent and nature of English language videos available on the Web 2.0 domain 'YouTube' that contain tobacco brand images or words. The authors conducted a YouTube search using five leading non-Chinese cigarette brands worldwide. The themes and content of up to 40 of the most viewed videos returned for each search were analysed: a total of 163 videos. A majority of the 163 tobacco brand-related videos analysed (71.2%, 95% CI 63.9 to 77.7) had pro-tobacco content, versus a small minority (3.7%) having anti-tobacco content (95% CI 1.4 to 7.8). Most of these videos contained tobacco brand content (70.6%), the brand name in the title (71.2%) or smoking imagery content (50.9%). One pro-smoking music video had been viewed over 2 million times. The four most prominent themes of the videos were celebrity/movies, sports, music and 'archive', the first three of which represent themes of interest to a youth audience. Pro-tobacco videos have a significant presence on YouTube, consistent with indirect marketing activity by tobacco companies or their proxies. Since content may be removed from YouTube if it is found to breach copyright or if it contains offensive material, there is scope for the public and health organisations to request the removal of pro-tobacco content containing copyright or offensive material. Governments should also consider implementing Framework Convention on Tobacco Control requirements on the internet, to further reduce such pro-tobacco content.

    Full Text Available Este artigo mostra como a televisão na era digital enfrenta o desafio da convergência de mídia. Na internet, a linguagem de TV não se resolve, tendo o texto e a edição de vídeos como suporte para uma nova linguagem. O vídeo, no mesmo tamanho e formato exibido na televisão, é praticamente desprezado pelo internauta e acaba acessado como consulta em trilhos próprios ao invés de ser um material informativo para o usuário. Para demonstrar como essa característica de leitura de informações na internet cria uma nova relação entre texto e vídeos na internet serão analisadas três reportagens do site G1, da Rede Globo. A inclusão de vídeos sem edição, diferentes das matérias veiculadas nos telejornais, geraram mais acessos, indicando as características do internauta e do que se procura em termos de vídeos na internet, ou seja, uma narrativa e uma linguagem construídas não apenas pelo veículo de comunicação, mas também a partir da interação com os internautas e da quebra de antigos paradigmas sobre as formas de se noticiarem um fato.

    Full Text Available Este texto é parte de um estudo sobre estratégias educativas utilizadas pelos programas de emagrecimento oferecidos via Internet e tem como objetivo descrever e analisar alguns elementos estruturantes desses sites. Observou-se que os mesmos utilizam estratégias que se aproximam mais da realidade cotidiana dos participantes, e que aspectos psicológicos e motivacionais são considerados importantes. Além disso, há uma tentativa de criar estratégias educacionais que transitem da concepção do "fazer dieta" para o conceito de reeducação alimentar concebida como "o comer de tudo, sem passar fome". Tal fato revela uma aliança entre as ciências da nutrição e a gastronomia, que representa um elo importante nas tentativas do resgate do prazer em comer. Destaca-se a importância de estudar tais estratégias, uma vez que o emagrecimento tem sido uma meta desejada por grande parte da população, seja com objetivo de ampliar a qualidade da saúde, seja com fins estéticos.This paper aims to describe and analyze some elements of diet programs offered on the Internet. The study observed that strategies used by the programs are familiar to people, and that psychological and motivational aspects are important. Therefore, there is an attempt to create educational strategies ranging from the concept of "doing diet" to "nutritional re-education". The latter is understood as "to eat everything, without starving". This fact unveils an alliance between the nutritional sciences and gastronomy, which greatly helps recovering the pleasure of eating. The text points out the importance of studying such strategies, mainly because losing weight is the objective of the largest part of the population, either for improving health or for aesthetical purposes.

    Full Text Available Vivemos em sociedades altamente midiatizadas e não somente atravessadas pela ação dos meios de comunicação de massa mas, também, pelas novas tensões que assume o processo de midiatização a partir do desenvolvimento das redes sociais em Internet. Ao reconhecer a natureza ambiental e construtiva dos meios de comunicação de massa é possível, também, considerar a midiatização como modalidade nuclear da construção da esfera pública. Neste contexto, este artigo pergunta sobre os modos onde o funcionamento do Facebook e os discursos aí expostos participam na configuração da esfera pública contemporânea, assim como, ademais, sobre o grau de novidade que mostra dita intervenção a respeito da exercida pelos tradicionais meios de comunicação de massa. Em função de articular as reflexões expostas com alguns dos eixos que tomou o debate teórico lançado pela análise que realizou Habermas sobre a gênese e as transformações estruturais da vida pública, este artigo enfoca nestes três seguintes aspectos: a gestão da visibilidade, da colocação pública ou publicação; o lugar que ocupa o diálogo, a deliberação e o dissenso; a condição múltipla e móvel da esfera pública atual.

    Internet marketing may accelerate the use of care based on genomic or tumor-derived data. However, online marketing may be detrimental if it endorses products of unproven benefit. We conducted an analysis of Internet websites to identify personalized cancer medicine (PCM) products and claims. A Delphi Panel categorized PCM as standard or nonstandard based on evidence of clinical utility. Fifty-five websites, sponsored by commercial entities, academic institutions, physicians, research institutes, and organizations, that marketed PCM included somatic (58%) and germline (20%) analysis, interpretive services (15%), and physicians/institutions offering personalized care (44%). Of 32 sites offering somatic analysis, 56% included specific test information (range 1-152 tests). All statistical tests were two-sided, and comparisons of website content were conducted using McNemar's test. More websites contained information about the benefits than limitations of PCM (85% vs 27%, P market one or more nonstandard tests as compared with standard tests (88% vs 44%, P = .04). © The Author 2015.

    The purpose of this study was to assess the feasibility of using live teleconferencing for teaching of new robotic-assisted surgical techniques. This was a prospective study with review of outcomes (Canadian Task Force classification II-3) in a community hospital. In 2009, our community hospital acquired the da Vinci Connect™ System, a technology which allows for live surgeon-to-surgeon interaction during robotic surgery via a secure internet connection. We utilized this technology from March 2009 through March 2011 to perform 28 live robotic surgeries that were observed by surgeons and hospital staff in 14 different US states as well as in France. We also had 14 episodes where new robotic surgeons in our facilities were mentored by experienced robotic surgeons in other geographic locations live through the da Vinci Connect internet connection. We performed two live surgeries for continuing medical education courses with live interactions between the course attendees and the console surgeon. Finally, one surgeon in our hospital proctored new surgeons remotely in distant sites on challenging cases. Utilizing computers that allow an experienced mentor surgeon to interact with less experienced surgeons on a live case is invaluable and presages the way we will train surgeons in the future. This feasibility study validates the need to pursue this technology for future education and training as well as for real-time collaboration.

    Over the past decade, the increasing availability of the World Wide Web has held out the possibility that the efficiency of scientific measurements could be enhanced in cases where experiments were being conducted at distant facilities. Examples of early successes have included X-ray diffraction (XRD) experimental measurements of protein crystal structures at synchrotrons and access to scanning electron microscopy (SEM) and NMR facilities by users from institutions that do not possess such advanced capabilities. Experimental control, visual contact, and receipt of results has used some form of X forwarding and/or VNC (virtual network computing) software that transfers the screen image of a server at the experimental site to that of the users' home site. A more recent development is a web services platform called Science Studio that provides teams of scientists with secure links to experiments at one or more advanced research facilities. The software provides a widely distributed team with a set of controls and screens to operate, observe, and record essential parts of the experiment. As well, Science Studio provides high speed network access to computing resources to process the large data sets that are often involved in complex experiments. The simple web browser and the rapid transfer of experimental data to a processing site allow efficient use of the facility and assist decision making during the acquisition of the experimental results. The software provides users with a comprehensive overview and record of all parts of the experimental process. A prototype network is described involving X-ray beamlines at two different synchrotrons and an SEM facility. An online parallel processing facility has been developed that analyzes the data in near-real time using stream processing. Science Studio and can be expanded to include many other analytical applications, providing teams of users with rapid access to processed results along with the means for detailed

    Expanding Internet-based interventions for substance use will have little benefit if heavy substance users are unlikely to have Internet access. This paper explored whether access to the Internet was a potential barrier to the provision of services for smokers, drinkers and illicit drug users. As part of a general population telephone survey of adults in Ontario, Canada, respondents were asked about their use of different drugs and also about their use of the Internet. Pack-a-day smokers were less likely (48%) to have home Internet access than non-smokers (69%), and current drinkers (73%) were more likely to have home access than abstainers (50%). These relationships remained true even after controlling for demographic characteristics. Internet access was less clearly associated with cannabis or cocaine use. Even though there is variation in access among smokers, drinkers and illicit drug users, the World Wide Web remains an excellent opportunity to potentially provide services for substance abusers who might never access treatment in person because, in absolute terms, the majority of substance abusers do use the Internet.

    Osteoporosis is a "pediatric disease with geriatric consequences." This article describes the development and pilot testing of an online system to educate high school students grades 9-12 about osteoporosis; an age where positive health changes could have long lasting effects. The intervention goal was to improve knowledge about osteoporosis and intent to adopt healthy bone practices. Online pre- and postintervention surveys evaluated participants' pre- and postintervention osteoporosis knowledge, attitudes, preventive practices, and postintervention intent to change healthy bone practices. Participants completed the Web-based program that provided detailed information about osteoporosis, and healthy bone practices, immediately after completing the pretest and just prior to completing the posttest. Eighty-nine students completed both the pre/posttests and were included in data analysis. Participants ranged in age from 13 to 17 and 75% were Caucasian (n = 65). Based on pre/posttest scores of 9 factual questions, students significantly improved their knowledge (p < .0001) and overall knowledge rating about osteoporosis at posttest (p < .001). Participants changed their perception regarding the disease's seriousness (p < .001), and considered adopting osteoporosis prevention practices. The study shows that an interactive educational Web site is an effective method for increasing awareness and understanding of osteoporosis in high school students.

    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.

    A low-cost usability engineering methodology (heuristic evaluation combined with small-scale expert assessment) is examined in the context of the design and development of a Web-based telemedicine system. Six experts - three human-computer interaction (HCI) experts and three medical-content experts - examined the Spacebridge to Russia Web site for usability. The HCI experts identified 52 interface problems using a set of ten usability criteria or heuristics; these problems ranged in severity from cosmetic to a major failure. The content experts completed a series of six simple tasks while describing their actions. The usage difficulties were related to the HCI problems identified and were primarily characterized by a mismatch of the designer model and the content expert model. This heuristic/usage methodology can provide an incremental benefit in a variety of other design activities. It is suggested herein that the combined heuristic/usage methodology should be included as a standard design component of dynamic telemedicine systems.

Argumento que embora haja uma íntima relação entre turismo sexual e desigualdade, a pobreza, nem sequer quando é extrema, garante o "sucesso" de um novo centro de turismo sexual. No marco de certas condições econômicas, aspectos culturais que se expressam na imbricação entre traços étnico/regionais e estilos de sexualidade operam à maneira de atração para o surgimento de novos alvos.

    The 2009-10 influenza pandemic was a major public health concern. Vaccination was recommended by the health authorities, but compliance was not optimal and perception of the presumed associated risks was high among the public. The Internet is increasingly being used as a source of health information and advice. The aim of the study was to investigate the characteristics of websites providing information about flu vaccine and the quality of the information provided. Website selection was performed in autumn 2010 by entering eight keywords in two of the most commonly used search engines (Google.com and Yahoo.com). The first three result pages were analysed for each search, giving a total of 480 occurrences. Page rank was evaluated to assess visibility. Websites based on Web 2.0 philosophy, websites merely displaying popular news/articles and single files were excluded from the subsequent analysis. We analysed the selected websites (using WHO criteria) as well as the information provided, using a codebook for pro/neutral websites and a qualitative approach for the adverse ones. Of the 89 websites selected, 54 dealt with seasonal vaccination, three with anti-H1N1 vaccination and 32 with both. Rank analysis showed that only classic websites (ones not falling in any other category) and one social network were provided on the first pages by Yahoo; 21 classic websites, six displaying popular news/articles and one blog by Google. Analysis of the selected websites revealed that the majority of them (88.8%) had a positive/neutral attitude to flu vaccination. Pro/neutral websites distinguished themselves from the adverse ones by some revealing features like greater transparency, credibility and privacy protection. We found that the majority of the websites providing information on flu vaccination were pro/neutral and gave sufficient information. We suggest that antivaccinationist information may have been spread by a different route, such as via Web 2.0 tools, which may be

    This study examined the current technology use of clients in the western Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) region and the preferences these current clients have for using new technologies to interact with WIC. Cross-sectional convenience sample for online survey of WIC clients over 2 months in 2011. A weighted sample of 8,144 participants showed that the majority of WIC clients have access to the Internet using a computer or mobile phone. E-mail, texting, and Facebook were technologies most often used for communication. Significant differences (P < .05) existed between age groups and Facebook use, education level and technology use for education delivery, and education level and use of video chat. Technologies should be considered for addressing WIC clients' needs, including use of text messaging and smartphone apps for appointments, education, and other WIC services; online scheduling and nutrition education; and a stronger Facebook presence for connecting with WIC clients and breastfeeding support.

    the aims of this survey were: (a) to evaluate the need of information after childbirth and what questions do 'new' mothers ask themselves; (b) to assess why and how women use the Internet to meet their need of information; (c) to describe how the respondents evaluate the reliability of the information found; (d) to understand how the information found on the Internet affects women's decision-making; and (e) to appreciate how health professionals react to the information found by the women. this study used a large web-based survey that was widely broadcasted on various websites and social networks. belgian women who had a child under 2 years old and who agreed to participate were included in the study. 349 questionnaires were valid for analyses. After childbirth, 90.5% of women admitted to using the Internet to seek information about themselves or about their baby, regardless of socioeconomic status or age. There were various reasons for seeking information on the Internet, but the most frequent reason the women expressed was to find information 'on their own' (88.1%). The most searched for topic was breastfeeding. The women believed that the information was quite useful (82.7%) but they assigned an average score of 5.3 out of 10 for the quality of the information they found on the Internet. Approximately 80% of the women felt that the Internet helped them control a decision that they made 'a little', 'often' or 'very often'. Professionals are not always willing to talk about information found on the Internet with mothers. Therefore, many women believed that health professionals should suggest reliable Internet websites for new mothers. the integration of the Internet and new technologies could be a useful tool during postpartum management.

  8. The Web planet: How the changing Internet divided Doctor Who fan fiction writers

    Full Text Available This paper analyzes the debate that arose in online Doctor Who fandom surrounding the switch to moderated submissions for "A Teaspoon and an Open Mind," the fandom's main fan fiction archive. As has been the case with many classic texts of science fiction and fantasy, from The Lord of the Rings on, the new adaptation of the cult series Doctor Who was the cause of much tension and conflict within the fandom. It has opened up the franchise to a vast new audience unschooled in the fandom's ways or the ways of fandom at large, and the change in archive policy served as an arena where many of these tensions came to a head. An in-depth analysis of this debate leads to the argument that the cultural logics of fandom and of participatory culture might be more separate than they initially appear. Some fans wholly embrace the ideals of Web 2.0 and argue for the archive as a nonhierarchical, communal space where all content is equal regardless of what standards it might not meet. Yet while their rhetoric resembles the ideas of academia about the potential of fandom as an educational space, other, more veteran fans reject academia, instead using the discourse of private enterprise and property rights, more commonly associated with the producers of texts than with their fans and poachers, to argue for the rights of site moderators to regulate content.

    The vast amount of heterogeneous data generated in various fields of neurosciences such as neuropsychopharmacology can hardly be classified using traditional databases. We present here the concept of a virtual archive, spatially referenced over a simplified 3D brain map and accessible over the Internet. A simple prototype (available at http://aquatics.crs4.it/neuropsydat3d) has been realized using current Web-based virtual reality standards and technologies. It illustrates how primary literature or summary information can easily be retrieved through hyperlinks mapped onto a 3D schema while navigating through neuroanatomy. Furthermore, 3D navigation and visualization techniques are used to enhance the representation of brain's neurotransmitters, pathways and the involvement of specific brain areas in any particular physiological or behavioral functions. The system proposed shows how the use of a schematic spatial organization of data, widely exploited in other fields (e.g. Geographical Information Systems) can be extremely useful to develop efficient tools for research and teaching in neurosciences.

    Full Text Available This work is part of the Youth Internet Sociabilities and Learning [YISL] research, developed by the UNESCO Chair in Youth, Education and Society at the Catholic University of Brasilia, during the period of 2011 to 2013. In this survey, the main goal was to investigate the perception of undergraduate students on the use of the internet in their learning processes. This is a quantitative and qualitative study in which the data was collected through questionnaires and focus groups conducted among students in the departments of Education, Literature and Mathematics of a private university in the Federal District, Brazil. It was found that the Internet is the means that college students use the most in their academic research, although the information to which they are exposed is of dubious quality. For most of them, the use of the Internet vitiates the writing capabilities of those who do not use cultural norms to communicate in the virtual space, favoring, thus, grammatical errors in academic works. From this study, it is concluded that this tool, if not correctly used, may negatively affect college students.

    The Internet offers adolescents unique opportunities to actively shape their own sexual media environment. The aim of this study was to gain in-depth insight into Dutch adolescents' motives, perceptions, and reflections toward Internet use for (a) finding information or advice related to romance and sexuality; (b) searching for and viewing pornographic or erotic material; and (c) romantic and sexual communication (i.e., cybersex/sexting). Data were collected through 12 Web-based focus groups (36 adolescents aged 16 to 19 years, 72.2% girls) and analyzed through three stages of open, axial, and selective coding. The themes that emerged from the focus-group discussions suggest that sex-related Internet use is a complex and ambivalent experience for adolescents. Sex-related Internet use seems an increasingly normalized and common phenomenon. Participants perceived the Internet as a useful source of sexual information, stimulation, inspiration, and communication. Yet they discussed a range of negative consequences and risks related to sex-related online behaviors, particularly concerning pornography's potential to create unrealistic expectations about sex and sexual attractiveness. Participants generally believed they had the necessary skills to navigate through the online sexual landscape in a responsible way, although they believed other young people could be influenced inadvertently and adversely by sex-related online content.

    Full Text Available O presente artigo tem como objetivo analisar, dentro do contexto específico de compras na internet, a relação entre características pessoais e intenções de compra, com o propósito de entender o papel da atitude ante a compra pela internet e da familiaridade do consumidor com compras on-line nessa relação. Uma pesquisa descritiva conclusiva foi elaborada visando compreender o efeito de quatro características pessoais: autoeficácia, inovatividade, necessidade de interação social e necessidade de interação sensorial, na familiaridade, na atitude ante a compra pela internet e na intenção de compra on-line. Com base na literatura, um modelo foi construído e testado, usando análise fatorial confirmatória para avaliar o modelo de medidas e análise de equações estruturais para testar as hipóteses deste trabalho. Ao todo, foram aplicados 233 questionários, e os resultados indicaram que existe uma relação significativa entre as características pessoais estudadas e familiaridade com compras na internet. A necessidade de interação social apresentou impacto direto na familiaridade e na atitude, destacando-se como uma característica-chave no processo de compra on-line. Ainda, como resultado, confirmou-se que a familiaridade medeia as relações entre as características pessoais e a atitude ante a compra na internet. Esta última exerce papel central na formação do comportamento de compra, sendo fortemente influenciada pela familiaridade e influenciando diretamente as intenções de compra. Como implicação teórica deste trabalho, tem-se o exame de questões ainda pouco exploradas no campo de conhecimento do comportamento do consumidor on-line, como o papel das características pessoais e da atitude na intenção de compra on-line. Como implicação gerencial, este trabalho proporciona aos administradores um entendimento maior sobre os fatores que influenciam a compra eletrônica.

    Full Text Available Fraudes na produção científica não são situações raras, mesmo na área da saúde. Entre elas incluem-se alguns tipos de má conduta em autoria, como o plágio e a prática de ghostwriting (escrever um artigo com o nome de outro autor patrocinada pela indústria farmacêutica. Um outro tipo particularmente nocivo para a ciência é o comércio de trabalhos científicos, que tem crescido na internet e tem sido freqüentemente noticiado na imprensa. OBJETIVOS: Analisar o comércio de trabalhos científicos na internet e o modo como são oferecidos esses serviços. MÉTODOS:Foram selecionadas 18 páginas eletrônicas nacionais que oferecem serviços de elaboração de artigos científicos, monografias, dissertações e teses. Para cada uma foi enviada mensagem solicitando informações sobre a elaboração de uma monografia de conclusão de um curso de especialização fictício. A pesquisa já havia sido realizada, de forma que suas características técnicas, éticas e bibliográficas já eram conhecidas pela autora. RESULTADOS: Dez empresas aceitaram a encomenda e, exceto por uma delas, não se opuseram às condições impostas: pesquisa de campo, aprovação por comitê de ética em pesquisa e utilização das normas de Vancouver. Seis não responderam e duas não aceitaram a encomenda alegando não ter colaboradores disponíveis. CONCLUSÃO: O comércio de trabalhos científicos é uma realidade que pode interferir negativamente na formação ética, científica e profissional de graduandos e pós-graduandos, bem como na produção científica, falseando dados e informações da literatura. Recomenda-se uma nova abordagem principalmente na avaliação de trabalhos de conclusão de cursos e monografias.Frauds in scientific production are not a rare phenomenon, even in the medical field.

Results by a master's research conducted by the application of investigative psychoanalytical method and content interpreted according to psychoanalysis reference of bonding configurations and group psychoanalysis. The research led us to recognize that, despite the possibility of knowing traces of the other's personality in a virtual bond, the meeting is bond's constitutive part. We conclude that, for the realization of a romantic bond, the Internet is characterized as a condition, from which the bond is constructed by stages like identification of intentions and values, mutual desire, confirmation of data as reality and the establishment of the first face to face encounter, in a process where good or bad results depend mostly of the maturity of the ones involved as well as of its physical presence contact.

    2001-06-01

    We describe a virtual web site hosting technology that enables educators in radiology to emblazon and make available for delivery on the world wide web their own interactive educational content, free from dependencies on in-house resources and policies. This suite of technologies includes a graphically oriented software application, designed for the computer novice, to facilitate the input, storage, and management of domain expertise within a database system. The database stores this expertise as choreographed and interlinked multimedia entities including text, imagery, interactive questions, and audio. Case-based presentations or thematic lectures can be authored locally, previewed locally within a web browser, then uploaded at will as packaged knowledge objects to an educator's (or department's) personal web site housed within a virtual server architecture. This architecture can host an unlimited number of unique educational web sites for individuals or departments in need of such service. Each virtual site's content is stored within that site's protected back-end database connected to Internet Information Server (Microsoft Corp, Redmond WA) using a suite of Active Server Page (ASP) modules that incorporate Microsoft's Active Data Objects (ADO) technology. Each person's or department's electronic teaching material appears as an independent web site with different levels of access--controlled by a username-password strategy--for teachers and students. There is essentially no static hypertext markup language (HTML). Rather, all pages displayed for a given site are rendered dynamically from case-based or thematic content that is fetched from that virtual site's database. The dynamically rendered HTML is displayed within a web browser in a Socratic fashion that can assess the recipient's current fund of knowledge while providing instantaneous user-specific feedback. Each site is emblazoned with the logo and identification of the participating institution. Individuals

    Informal and formal lifelong learning is essential at university and in the workplace. Apart from classical learning techniques, Web 2.0 tools can be used. It is controversial whether there is a so-called net generation amongst people under 30. To test the hypothesis that a net generation among students and young veterinarians exists. An online survey of students and veterinarians was conducted in the German-speaking countries which was advertised via online media and traditional print media. 1780 people took part in the survey. Students and veterinarians have different usage patterns regarding social networks (91.9% vs. 69%) and IM (55.9% vs. 24.5%). All tools were predominantly used passively and in private, to a lesser extent also professionally and for studying. The use of Web 2.0 tools is useful, however, teaching information and media skills, preparing codes of conduct for the internet and verification of user generated content is essential.

    The relationships of Internet use, web communication, and sources of social support with adolescent self-injurious thoughts and behaviors (SITBs) in Taiwan were investigated. The study sample of 391 12 to 18-year-olds was selected from nine public high schools. Findings show that girls are more likely to have SITBs, except for suicide gestures. Web communication is a risk factor for SITBs in boys but not in girls. Family support is protective in both genders. Support from friends is protective and support from significant others was a risk factor for suicide plans in girls. Support from virtual social communities can have both positive and negative effects on adolescent SITBs, with different effects by gender. © 2014 The American Association of Suicidology.

    In recent years, lifestyle products have emerged to help improve people's physical and mental performance. The Internet plays a major role in the spread of these products. However, the literature has reported issues regarding the authenticity of medicines purchased from the Internet and the impact of counterfeit medicines on public health. Little or no data are available on the authenticity of lifestyle products and actual toxicity associated with their use and misuse. Our aim was to investigate consumer and patient attitudes toward the purchase of lifestyle products from the Internet, their knowledge of product authenticity and toxicity, and their experiences with counterfeit lifestyle products. A Web-based study was performed between May 2014 and May 2015. Uniform collection of data was performed through an anonymous online questionnaire. Participants were invited worldwide via email, social media, or personal communication to complete the online questionnaire. A total of 320 participants completed the questionnaire. The results of the questionnaire showed that 208 (65.0%) participants purchased lifestyle products from the Internet mainly due to convenience and reduced cost. More than half (55.6%, 178/320) of participants purchased cosmetic products, whereas only a minority purchased medicinal products. Yet, 62.8% (201/320) of participants were aware of the presence of counterfeit lifestyle products from the Internet, and 11.9% (38/320) experienced counterfeit products. In only 0.9% (3/320) of those cases were counterfeit lifestyle products reported to authorities. Moreover, 7.2% (23/320) of the participants experienced adverse effects due to counterfeit lifestyle products. In summary, patients experienced counterfeit lifestyle products that resulted in adverse effects on their health. Although certain adverse effects were reported in this study, counterfeit products were underreported to authorities. Further public awareness campaigns and patient education are

Foi desenvolvida e aplicada uma survey, baseada nos pressupostos da Teoria do Comportamento Planejado (AJZEN, 1991. Foi também avaliada a inclusão dos construtos Emoção Positiva e Emoção Negativa no Modelo de Ajzen, proposta por Perugini e Bagozzi (2001. Para o tratamento estatístico dos dados foi utilizada a Modelagem de Equações Estruturais. Após as análises identificou-se que os construtos Atitude em Relação ao Comportamento, Norma Subjetiva e Controle Comportamental Percebido são significantes, corroborando assim a validade do modelo proposto. Observou-se ser significativa a inclusão do construto Emoção Positiva, pois se obteve um coeficiente de regressão -R²- de 65%, maior do que o obtido sem a inclusão.

    2008-02-01

    Full Text Available While the discussion on the integrity of data obtained from Web- delivered experiments is mainly about issues of method and control (Mehler, 1999; McGraw et al., 2000; Auditory, 2007, this comment stresses the potential that Web- based experiments might have for studies in music perception. It is argued that, due to some important advances in technology, Web-based experiments have become a reliable source for empirical research. Next to becoming a serious alternative to a certain class of lab-based experiments, Web-based experiments can potentially reach a much larger, more varied and intrinsically motivated participant pool. Nevertheless, an important challenge to Web-based experiments is to control for attention and to make sure that participants act as instructed; Interestingly, this is not essentially different from experiments that are performed in the laboratory. Some practical solutions to this challenge are proposed.

Paulo, mais precisamente à seção "Especiais", intitulado "Nas páginas do Estadão, a luta contra a censura". Sob a orientação da Análise do Discurso de matriz francesa, fundada por Michel Pêcheux, com o apoio dos estudos sobre o dialogismo de Mikhail Bakhtin e das discussões sobre o virtual de Pierre Lévy, esse trabalho visa compreender o modo como são produzidos efeitos de sentido sobre o entrelaçamento de vozes que compõem as páginas web analisadas, bem como analisar qual a formação imaginária que tais sites constroem de si e de seus leitores através do discurso eletrônico. Inseridos em um ambiente eletrônico, os sites que abrigam acervos de jornais e revistas, além de constituir um arquivo sob uma perspectiva histórica, também tentam construir uma imagem de si e/ou do jornal que abrigam. Entendendo que a rede mundial de computadores é uma realidade, destacamos a importância de se estudar o discurso presente nos sites como forma de romper com a suposta neutralidade da imprensa e da web.

    The study evaluated the validity and reproducibility of the food consumption section of the questionnaire Food Intake and Physical Activity of School Children (Web-CAAFE), an Internet-based software for the qualitative measurement of food consumption by recalling the previous day. A total of 390 students in grades 2 to 5 (7 to 15 years) of a semi-integral public school participated in the study. The validity was tested by comparing the report in the Web-CAAFE and the direct observation of food consumed in the school in the previous day. The reproducibility was evaluated in a sub-sample of 92 schoolchildren, by comparing repeated reports in the Web-CAAFE on the same day. Probabilities of accuracy in the Web-CAAFE report in relation to the observation (matches, omissions and intrusions and respective 95% confidence intervals) among seven food groups were estimated through multinomial logistic regression. The average for the match rate was 81.4% (variation: 62% sweets and 98% beans); for the omission rate was 16.2% (variation between 2.1% dairy products and 28.5% sweets); for the intrusion rate was 7.1% (variation between 1.3% beans and 13.8% cereals). Sweets, cereals and processed foods, snack foods and fried foods simultaneously exhibited higher rates of omission and intrusion. Students 10 years of age or older had lower probabilities of intruding food items. There were no significant variations in the accuracy of the report between repeated measures. The Web-CAAFE was a valid and reliable instrument for the evaluation of food consumption, when applied to students in grades 2 to 5 of public schools.

    Full Text Available A transparência com que as empresas disponibilizam informações ao mercado tem sido reconhecida como um dos principais pilares das boas práticas de governança. Paralelamente, o antigo paradigma da comunicação passa por transformações decorrentes da era digital. As empresas estão aumentando a utilização da Internet como meio de relacionamento com os investidores, e com isso estão oferecendo maiores graus de transparência ao mercado. Este artigo tem como objetivo verificar a existência de associações entre características das empresas e a disseminação voluntária de informações financeiras usando a rede mundial de computadores, tomando como referência as empresas brasileiras. O estudo consiste em cross section realizado a partir de dados referentes a 291 empresas não-financeiras listadas na Bovespa em 2002. As evidências sugerem que o maior tamanho da empresa, assim como o menor retorno anual de suas ações, está associado a maior soma de informações financeiras disseminadas no site corporativo.

    Informatics is a broad field encompassing artificial intelligence, cognitive science, computer science, information science, and social science. The goal of this review is to illustrate how Web 2.0 information technologies could be used to improve anesthesia education. Educators in all specialties of medicine are increasingly studying Web 2.0 technologies to maximize postgraduate medical education of housestaff. These technologies include microblogging, blogs, really simple syndication (RSS) feeds, podcasts, wikis, and social bookmarking and networking. 'Anesthesia 2.0' reflects our expectation that these technologies will foster innovation and interactivity in anesthesia-related web resources which embraces the principles of openness, sharing, and interconnectedness that represent the Web 2.0 movement. Although several recent studies have shown benefits of implementing these systems into medical education, much more investigation is needed. Although direct practice and observation in the operating room are essential, Web 2.0 technologies hold great promise to innovate anesthesia education and clinical practice such that the resident learner need not be in a classroom for a didactic talk, or even in the operating room to see how an arterial line is properly placed. Thoughtful research to maximize implementation of these technologies should be a priority for development by academic anesthesiology departments. Web 2.0 and advanced informatics resources will be part of physician lifelong learning and clinical practice.

    This paper presents a summary of web-based data collection, impact evaluation, and user evaluations of an Internet-based peer support program for Ménière's disease (MD). The program is written in html-form. The data are stored in a MySQL database and uses machine learning in the diagnosis of MD. The program works interactively with the user and assesses the participant's disorder profile in various dimensions (i.e., symptoms, impact, personal traits, and positive attitude). The inference engine uses a database to compare the impact with 50 referents, and provides regular feedback to the user. Data were analysed using descriptive statistics and regression analysis. The impact evaluation was based on 740 cases and the user evaluation on a sample of 75 cases of MD respectively. The web-based system was useful in data collection and impact evaluation of people with MD. Among those with a recent onset of MD, 78% rated the program as useful or very useful, whereas those with chronic MD rated the program 55%. We suggest that a web-based data collection and impact evaluation for peer support can be helpful while formulating the rehabilitation goals of building the self-confidence needed for coping and increasing social participation.

    Full Text Available Este estudio tiene como objetivo principal analizar la efectividad de los servicios bancarios a través de Internet en Chile provistos por trece bancos nacionales. Para ello se consideraron dos etapas, la primera correspondió a la evaluación de funcionalidades de los sitios Web bancarios, utilizando una adaptación del modelo de evaluación de sitios Web de Hersey, y la segunda a la evaluación de los servicios según las percepciones de los clientes. Para la determinación de las funcionalidades fue necesario detectar la presencia o ausencia de treinta y siete elementos evaluados, según lo cual fue posible clasificar al sector bancario chileno en términos de lo que ofrece o no cada institución. Por otra parte, la encuesta aplicada tanto a usuarios como no usuarios de la banca en línea permitió conocer variados factores referentes al uso y no uso de los servicios. A pesar de que existen algunos aspectos en los que la banca nacional se desempeña sólo de forma regular, en el contexto global lo hace con un alto grado de efectividad. Además, el buen desempeño en el contexto general se hace evidente al observar la gran equiparidad existente entre los resultados nacionales y los de la banca neocelandesaThe main objective of this study is to analyze the effectiveness of the services of Internet banking provided by thirteen Chilean banking institutions. To achieve this objective, two stages were considered. The first stage corresponded to the evaluation of the functionalities offered by the banking Web sites, using an adaptation of the Hersey Web site evaluation model. The second stage corresponded to the evaluation of the services according to the clients' perceptions. In order to determine the functionalities offered by banking Web sites it was necessary to detect the presence or absence of thirty seven elements. This approach permitted to rank the Chilean banking sector based on the Internet offer of each institution. On the other hand

    Full Text Available The "Brazilian bill of rights for internet users," or "marco civil," has been under consideration at the brazilian congress since 2011. Marco civil's provisions for network neutrality have been particularly controversial. Proponents of network neutrality in Brazil advocate for the "equal treatment" of all data packets, including banning internet service providers from offering to content providers the option to purchase enhanced quality of service in the delivery of data packets. These network neutrality rules conflict with the other goals and principles of marco civil-particularly goals to promote internet access, to foster innovation, and to protect the constitutional right of freedom of speech and the free flow of information.A "carta Brasileira de direitos dos usuários da internet," ou "marco civil," tramita no congresso Brasileiro desde 2011.

Essas disposições relativas à neutralidade de rede conflitam com outros objetivos e princípios do marco civil - especialmente os objetivos de promover o acesso à internet, promover a inovação, e garantir o direito constitucional de liberdade de expressão e informação.

    Full Text Available A presente pesquisa objetivou identificar o comportamento de busca de informação na Internet de bibliotecários e estudantes de ensino médio em oito escolas particulares dos municípios de Itajaí e Florianópolis, estado de Santa Catarina, Brasil. Este estudo entende que o desafio crítico para as escolas é possibilitar o aprendizado a partir de uma variedade de fontes de informação, pois a tecnologia, particularmente a Internet, modifica o ambiente de aprendizagem na escola. Os objetivos desta pesquisa foram averiguar como os bibliotecários compreendem o processo de busca de informação na Internet pelos estudantes e como prestam auxílio a eles, bem como averiguar como se processa a busca de informação pelos estudantes. Os instrumentos de coleta de dados utilizados na pesquisa foram um questionário aplicado a 8 bibliotecários, mais um questionário e um roteiro aplicados a 38 estudantes. A pesquisa teve abordagem quanti-qualitativa e análise de conteúdo. Emprega os pressupostos teóricos do Information Search Process de Carol Kuhlthau para investigar como os estudantes buscam a informação. As análises dos dados permitiram inferir que os bibliotecários avaliam que a busca de informação realizada pelos estudantes é um processo que desenvolvem de forma autônoma e com facilidade, que estes atingiram uma percepção mais acurada da Internet, e que são otimistas em relação à informação que recuperam, ainda que incerteza e dúvida sejam sentimentos presentes no decorrer da busca de informação.

  15. How happy is your web browsing? A model to quantify satisfaction of an Internet user searching for desired information

    We feel happy when web browsing operations provide us with necessary information; otherwise, we feel bitter. How to measure this happiness (or bitterness)? How does the profile of happiness grow and decay during the course of web browsing? We propose a probabilistic framework that models the evolution of user satisfaction, on top of his/her continuous frustration at not finding the required information. It is found that the cumulative satisfaction profile of a web-searching individual can be modeled effectively as the sum of a random number of random terms, where each term is a mutually independent random variable, originating from ‘memoryless’ Poisson flow. Evolution of satisfaction over the entire time interval of a user’s browsing was modeled using auto-correlation analysis. A utilitarian marker, a magnitude of greater than unity of which describes happy web-searching operations, and an empirical limit that connects user’s satisfaction with his frustration level-are proposed too. The presence of pertinent information in the very first page of a website and magnitude of the decay parameter of user satisfaction (frustration, irritation etc.) are found to be two key aspects that dominate the web user’s psychology. The proposed model employed different combinations of decay parameter, searching time and number of helpful websites. The obtained results are found to match the results from three real-life case studies.

    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.

    Due to limited regulation of websites, the quality and content of online health-related information has been questioned as prior studies have shown that websites often misrepresent orthopaedic conditions and treatments. Kinesio tape has gained popularity among athletes and the general public despite limited evidence supporting its efficacy. The primary objective of this study was to assess the quality and content of Internet-based information on Kinesio taping. An Internet search using the terms "Kinesio tape" and "kinesiology tape" was performed using the Google search engine. Websites returned within the first two pages of results, as well as hyperlinks embedded within these sites, were included in the study. These sites were subsequently classified by type. The quality of the website was determined by the Health On the Net (HON) score, an objective metric based upon recommendations from the United Nations for the ethical representation of health information. A content analysis was performed by noting specific misleading versus balanced features in each website. A total of 31 unique websites were identified. The majority of the websites (71%) were commercial. Out of a total possible 16 points, the mean HON score among the websites was 8.9 points (SD 2.2 points). The number of misleading features was significantly higher than the balanced features (p information. It is of ever-increasing importance that healthcare providers work to ensure that reliable, balanced, and accurate information be available to Internet users. IV.

    Full Text Available Abstract Background Previous studies reported that social phobia is associated with a history of child maltreatment. However, most of these studies focused on physical and sexual maltreatment whilst little is known about the specific impact of emotional abuse and neglect on social anxiety. We examined the association between emotional maltreatment, including parental emotional maltreatment as well as emotional peer victimization, and social anxiety symptoms in subjects with various degrees of social anxiety. Methods The study was conducted as a web-based Internet survey of participants (N = 995 who had social anxiety symptoms falling within the high range, and including many respondents who had scores in the clinical range. The assessment included measures of child maltreatment, emotional peer victimization, social anxiety symptoms and general psychopathology. Results Regression and mediation analyses revealed that parental emotional maltreatment and emotional peer victimization were independently related to social anxiety and mediated the impact of physical and sexual maltreatment. Subjects with a history of childhood emotional maltreatment showed higher rates of psychopathology than subjects with a history of physical maltreatment. Conclusions Although our findings are limited by the use of an Internet survey and retrospective self-report measures, data indicated that social anxiety symptoms are mainly predicted by emotional rather than physical or sexual types of victimization.

Previous studies found information related to back pain poor and often contradictory to current guidelines. Wellness has become a common topic in the field of chiropractic and accrediting agencies have standards on delivery of wellness-based content in college curricula as well as directives for clinical applications. The purpose of this study was to evaluate the quality of the information on the Internet using the terms "chiropractic wellness," or "wellness chiropractic". Methods Five commonly used search engines were selected and the first 10 sites found using the strategy above were evaluated by two raters. Demographic assessments of the sites were made along with whether they were Health on the Net Foundation (HON certified, contained standard wellness content, mentioned any Healthy People Focus Areas, and other chiropractic topics. Kappa statistics compared inter-rater agreement. Results Potential patients appeared to be the audience 87% of the time and a private doctor of chiropractic appeared to be the typical site owner. The sites usually promoted the provider. No sites displayed HON certification logo nor did any appear to meet the HON certification criteria. Twenty-six sites (55% promoted regular physical activity in some manner and 18 (38% had information on health risks of tobacco. Four (9% had mental health or stress-reduction content but none had information supportive of vaccination. Some had information contradictory to common public health measures. Conclusions Patients searching the Internet for chiropractic wellness information will often find useless information that will not help them maintain health or become well. Most simply market the chiropractic practice or allow for a patients to provide personal information in exchange for more 'wellness' information. More research should be done on how

    Full Text Available There are expectations that stem cell therapy (SCT will treat many currently untreatable diseases. The Internet is widely used by patients seeking information about new treatments, and hence, analyzing websites is a representative sample of the information available to the public. Our aim was to understand what information the public would find when searching for information on SCT on Google, as this would inform us on how lay people form their knowledge about SCT. We analyzed the content and information quality of the first 200 websites returned by a Google.com search on SCT. Most websites returned were from treatment centers (TCs, 44% followed by news and medical professional websites. The specialty most mentioned in non-TC websites was “neurological” (67%, followed by “cardiovascular” (42%, while the most frequent indication for which SCT is offered by TCs was musculoskeletal (89% followed by neurological (47%. 45% of the centers specialized in treating 1 specialty, 10% offer 2, and 45% offered between 3 and 18 different specialties. Of the 78 TCs, 65% were in the USA, 23% in Asia, and 8% in Latin America. None of the centers offered SCT based on embryonic cells. Health information quality (JAMA score, measuring trustworthiness was lowest for TCs and commercial websites and highest for scientific journals and health portals. This study shows a disconnection between information about SCT and what is actually offered by TCs. The study also shows that TCs, potentially acting in a regulatory gray area, have a high visibility on the Internet.

    eHealth, mHealth and "Web 2.0" social media strategies can effectively reach and engage key populations in HIV prevention across the testing, treatment, and care continuum. To assess how these tools are currently being used within the field of HIV prevention and care, we systematically reviewed recent (2013-2014) published literature, conference abstracts, and funded research. Our searches identified 23 published intervention studies and 32 funded projects underway. In this synthesis we describe the technology modes applied and the stages of the HIV care cascade addressed, including both primary and secondary prevention activities. Overall trends include use of new tools including social networking sites, provision of real-time assessment and feedback, gamification and virtual reality. While there has been increasing attention to use of technology to address the care continuum, gaps remain around linkage to care, retention in care, and initiation of antiretroviral therapy.

    A Internet posicionou a rádio num ambiente digital sem precedentes, com a produção e gestão de novos conteúdos áudio. A estrutura da comunicação foi alterada e continua em desenvolvimento, razão pela qual, devemos tentar compreender as implicações desta mudança ao nível dos procedimentos, da apresentação dos conteúdos e suas consequências. Este trabalho propõe-se a uma análise exaustiva das páginas online das principais rádios de informação portuguesas e a uma comparação com aquilo que pode constituir um modelo alternativo, o site da BBC Radio. As principais conclusões apontam para as vantagens que o modelo BBC impõe no cenário mediático, embora insuficientes ao verificar que apesar de proporcionar oportunidades aos seus ouvintes de intervirem na esfera pública, essa ligação nem sempre é bem conseguida.

Esta investigación entrevistó 20 universitarios de 18 años, de ambos sexos, e inves - tigó si internet introduce nuevas formas de relaciones afectivas entre ellos. Las fron - teras entre lo público y lo privado en internet referentes a las relaciones amorosas surgieron como cuestión. Se discuten los efectos de la publicación de acontecimien - tos de la vida amorosa en dos perspectivas: analizando fronteras entre lo público y lo privado, y reflexionando sobre cuestiones subjetivas que involucran esa publici - tación. A pesar de que los entrevistados critican la publicación de la vida privada en los medios digitales, reconocen que es una exigencia de la cultura actual. Se verificó que aunque la ausencia de conflictos causada por el desencuentro de cuerpos puede alimentar la ilusión de relación perfecta, los lazos amorosos mediados por internet presentan complejidad equiparable a la de las relaciones amorosas no virtuales.

Las diferentes versiones del software se ordenan con un número que sólo cambia cuando se rehace el programa, mientras que las mejoras parciales se indican con un número posterior a un punto decimal. Web 2.0 destaca que Internet ha dado un salto cualitativo respecto del Internet primitivo, la Web 1.0. Este cambio proviene no sólo del incremento de la difusión del uso de un nuevo medio de comunicación, Internet (éste sería todavía un cambio meramente cuantitativo, sino del desarrollo de aplicaciones (blogs, wikis, Flickr, YouTube, Facebook, MySpace... que han abaratado los costes de utilizar la red de forma interactiva y creativa, han generado comunidades colaborativas, y han permitido que tanto la producción como la difusión de contenidos se encuentren efectivamente descentralizados.

    Background Celiac disease is an autoimmune disease that affects approximately 1% of the US population. Disease is characterized by damage to the small intestinal lining and malabsorption of nutrients. Celiac disease is activated in genetically susceptible individuals by dietary exposure to gluten in wheat and gluten-like proteins in rye and barley. Symptoms are diverse and include gastrointestinal and extraintestinal manifestations. Treatment requires strict adherence to a gluten-free diet. The Internet is a major source of health information about celiac disease. Nonetheless, information about celiac disease that is available on various websites often is questioned by patients and other health care professionals regarding its reliability and content. Objectives To determine the accuracy, comprehensiveness, transparency, and readability of information on 100 of the most widely accessed websites that provide information on celiac disease. Methods Using the search term celiac disease, we analyzed 100 of the top English-language websites published by academic, commercial, nonprofit, and other professional (nonacademic) sources for accuracy, comprehensiveness, transparency, and reading grade level. Each site was assessed independently by 3 reviewers. Website accuracy and comprehensiveness were probed independently using a set of objective core information about celiac disease. We used 19 general criteria to assess website transparency. Website readability was determined by the Flesch-Kincaid reading grade level. Results for each parameter were analyzed independently. In addition, we weighted and combined parameters to generate an overall score, termed website quality. Results We included 98 websites in the final analysis. Of these, 47 (48%) provided specific information about celiac disease that was less than 95% accurate (ie, the predetermined cut-off considered a minimum acceptable level of accuracy). Independent of whether the information posted was accurate, 51 of

In the images which portray the medical professional, this is not different. However, there has been much questioned what symbol is related to this profession association. Currently, with the increased range of Internet search websites and its high number of access, a few images and symbols which connote or denote medical sites can be seized from a simple search. In this perspective, this study aims to analyze the social representation assigned to the medical professional through search websites as well as the symbols that are associated with this profession. This is an exploratory-descriptive study of qualitative and quantitative approach in which images were researcherd in five search sites available on different web, namely: www.google.com, www.ask.com, www.bing.com, www.yahoo.com and www.uol.com. For this, descriptors such as “médico”, “médica” and “profissionalmédico” were used. All posted images were collected in a period of 30 continuous days. Then, images were grouped into categories. It is worth mentioning, the images that only portray the everyday and images that portray show cartoons and famous or historical personalities were excluded. The images in different internet search websites were classified into diverse categories, among them lovingness, religion, leadership, teamwork, distance between doctor and patient, the profession, controversial, personal protective equipment, stethoscope, symbol, hospital equipment, records health and others. The categories that presented more frequently were: the profession, teamwork, stethoscope and health record. From this, we might infer that the doctor is a figure often linked to work, mainly because it routinely represented by instruments of his profession.

    Full Text Available Por meio do presente artigo, propomos conhecer e refletir sobre as recentes possibilidades de organização, representação e recuperação da informação proporcionada pelo advento da Web 2.0, tratando, aqui, especificamente, do uso da etiquetagem e da folksonomia. Buscou-se explorar representações conceituais e pretendeu-se compreender as potencialidades destes conceitos baseados em sistemas virtuais de organização e representação informacional. Assim, buscou-se refletir sobre o que leva os usuários a executar a etiquetagem dos recursos da Web e analisar como essa motivação se relaciona com o objetivo de recuperação da informação. A pesquisa apoiou-se em uma investigação teórica, com revisão de literatura sobre indexação, usuários e esquemas de representação do conhecimento na Internet. Geralmente, o que determina a utilização da etiquetagem varia entre as pessoas e os sistemas utilizados. Não é sempre que as etiquetas são atribuídas com o intuito de terem audiência e, por vezes, o que se quer é organizar os próprios dados. Entende-se, por meio deste estudo, que cada indivíduo representa um caso que requer atenção específica. Não é possível estudar, um a um, todos os grupos e perfis de usuários da informação. Faz-se necessário reunir grupos com características similares.

    Library resources are prevalent on the Internet. Library catalogs, electronic books, electronic periodicals, periodical indexes, reference sources, and U.S. Government documents are available by telnet, Gopher, World Wide Web, and FTP. Comparatively few copyrighted library resources are available freely on the Internet. Internet implementations of library resources can add useful features, such as full-text searching. There are discussion lists, Gophers, and World Wide Web pages to help users keep up with new resources and changes to existing ones. The future will bring more library resources, more types of library resources, and more integrated implementations of such resources to the Internet.

    Full Text Available It has now become quite obvious that the Internet has brought significant changes to our society and a break on how we lived before its emergence. It is still too early to assess the impact on society of the new services at our disposal, such as the capacity to communicate faster and cheaper on a global scale, access information and, perhaps more importantly, to produce and disseminate information in a way that is accessible to all.It is clear that the advent of the Information Society implies changes in our society that constitute a point of no return. However, contrary to what happened when we entered the Industrial Age about three centuries ago, when the changing process was slow and led by older individuals, these days the entrance into the Information Society is taking place rapidly and the decisive players are younger people. The global nature of the Internet, the possibility of producing and distributing any type of content in digital form at almost zero cost, as well as the vast number of people who use the web, have highlighted the need for new forms of intervention in a sector where there are many types of players. It is in this context that the problem of Internet Governance becomes a very current issue, inasmuch as one feels the need to guarantee a diversity of rights and duties, which may appear difficult to reconcile.This paper presents a brief overview of the main players and initiatives which, in the field of Internet Governance, have tried to contribute to turning this network into a factor for social development and democraticity on a global scale.

Seu uso deveria ser descriminado". A partir da aplicação de instrumentos e técnicas qualitativas de análise e tabulação de discursos aos depoimentos contidos nesse fórum, chegou-se à definição de seis grandes tipos de discurso do sujeito coletivo sobre a temática das drogas, da saúde, da doença e da liberdade, presentes, na qualidade de representações sociais, no imaginário brasileiro atual. De acordo com uma dada visão da Educação, o enunciado dessas representações permite o estabelecimento das pré-condições necessárias para qualquer intervenção educativa na problemática em questão.This paper takes a Health Education perspective to analyze a debate forum on the Brazilian Internet site entitled "Universo On-Line", in which the following questions were addressed: "Do you believe that marijuana is harmful to one's health?" "In your opinion, should marijuana use be decriminalized?" By applying qualitative discourse analysis techniques to responses from the forum, we were able to identify six main types of discourse, reflecting the opinions of six "collective subjects" concerning drugs, health, disease, and freedom and existing as social representations in the current Brazilian collective imagination. Research on these social representations allows one to establish criteria for intervention in the field of Health Education

    Background There is concern that the internet is playing an increasing role in self-harm and suicide. In this study we systematically review and analyse research literature to determine whether there is evidence that the internet influences the risk of self-harm or suicide in young people. Methods An electronic literature search was conducted using the PsycINFO, MEDLINE, EMBASE, Scopus, and CINAHL databases. Articles of interest were those that included empirical data on the internet, self-harm or suicide, and young people. The articles were initially screened based on titles and abstracts, then by review of the full publications, after which those included in the review were subjected to data extraction, thematic analysis and quality rating. Results Youth who self-harm or are suicidal often make use of the internet. It is most commonly used for constructive reasons such as seeking support and coping strategies, but may exert a negative influence, normalising self-harm and potentially discouraging disclosure or professional help-seeking. The internet has created channels of communication that can be misused to ‘cyber-bully’ peers; both cyber-bullying and general internet use have been found to correlate with increased risk of self-harm, suicidal ideation, and depression. Correlations have also been found between internet exposure and violent methods of self-harm. Conclusions Internet use may exert both positive and negative effects on young people at risk of self-harm or suicide. Careful high quality research is needed to better understand how internet media may exert negative influences and should also focus on how the internet might be utilised to intervene with vulnerable young people.

Al contrario, las versiones web reproducen la esencia de sus ediciones impresas de un modo que resulta muy similar para los lectores. La búsqueda de historias online puede ser un proceso que conlleva numerosos saltos de página y desplazamientos por la pantalla, pero sólo unas pocas informaciones tienen elementos añadidos, como hiperenlaces a información adicional, imágenes o recursos interactivos. Las versiones de Internet no suelen añadir ni cambiar el texto de los artículos, y su presentación es visualmente escasa, especialmente comparada con la impresa, que tiene una variedad tipográfica más rica y que presenta muchas más imágenes. Los resultados sugieren que los editores de la edición impresa utilizan la presencia de Internet como un lugar de bajo coste que conserva su posición en el mercado estadounidense y levanta una barrera a la entrada de competidores regionales y alternativas ideológicas en la arena informativa de Estados Unidos.Abstract: U.S. newspapers that publish electronic editions on the Internet do not appear to reinvent themselves on line. Instead the Web versions reproduce the substance of their print editions in a way that relates similarly to readers. Reaching stories on line can be a process involving multiple screen jumps and scrolls, and only a few stories have added features, such as hyper-links to additional information, images, or interactive resources. Newspaper stories on line differ very little from those printed in the originating newspapers. The Internet versions do not usually add to or change the text of the stories, and their presentation is visually meagre, especially compared to print, which has a richer typographical range and presents many more images.

    The benefits to medical practitioners of using the Internet are growing rapidly as the Internet becomes easier to use and ever more biomedical resources become available on line. The Internet is the largest computer network in the world; it is also a virtual community, larger than many nation states, with its own rules of behaviour or "netiquette." There are several types of Internet connection and various ways of acquiring a connection. Once connected, you can obtain, free of charge, programs that allow easy use of the Internet's resources and help on how to use these resources; you can access many of these resources through the hypertext references in the on line version of this series (go to http:@www.bmj.com/bmj/ to reach the electronic version). You can then explore the various methods for accessing, manipulating, or disseminating data on the Internet, such as electronic mail, telnet, file transfer protocol, and the world wide web. Results from a search of the world wide web for information on the rare condition of Recklinghausen's neurofibromatosis illustrate the breadth of medical information available on the Internet.

    2013-03-28

    What is the Web? What makes it work? And is it dying? This paper is drawn from a talk delivered by Prof. Zittrain to the Royal Society Discussion Meeting 'Web science: a new frontier' in September 2010. It covers key questions about the way the Web works, and how an understanding of its past can help those theorizing about the future. The original Web allowed users to display and send information from their individual computers, and organized the resources of the Internet with uniform resource locators. In the 20 years since then, the Web has evolved. These new challenges require a return to the spirit of the early Web, exploiting the power of the Web's users and its distributed nature to overcome the commercial and geopolitical forces at play. The future of the Web rests in projects that preserve its spirit, and in the Web science that helps make them possible.

    Lukose, Rajan Mathew

    The World Wide Web and the Internet are rapidly expanding spaces, of great economic and social significance, which offer an opportunity to study many phenomena, often previously inaccessible, on an unprecedented scale and resolution with relative ease. These phenomena are measurable on the scale of tens of millions of users and hundreds of millions of pages. By virtue of nearly complete electronic mediation, it is possible in principle to observe the time and ``spatial'' evolution of nearly all choices and interactions. This cyber-space therefore provides a view into a number of traditional research questions (from many academic disciplines) and creates its own new phenomena accessible for study. Despite its largely self-organized and dynamic nature, a number of robust quantitative regularities are found in the aggregate statistics of interesting and useful quantities. These regularities can be understood with the help of models that draw on ideas from statistical physics as well as other fields such as economics, psychology and decision theory. This thesis develops models that can account for regularities found in the statistics of Internet congestion and user surfing patterns and discusses some practical consequences. practical consequences.

    2014-03-01

    Full Text Available O objetivo neste artigo é analisar de que forma trabalhadores de uma empresa utilizaram o humor para manifestar-se contra demissões e terceirizações ocorridas nos anos 2000. Enquanto ela pregava a implantação de uma nova maneira de ser da empresa, que seria mais moderna, transparente e participativa, os trabalhadores produziram dois vídeos, postados no YouTube, para contar outra história, ridicularizar o discurso oficial e protestar. Ao combinar a utilização do humor com a Internet, os trabalhadores demonstraram sua capacidade de atualizar-se e encontrar novas formas de manifestar-se diante das situações vividas por eles, o que parece ter ampliado seu poder na luta simbólica. Embora as demissões e terceirizações não tenham sido revertidas, a "nova" gestão foi substituída pelos acionistas após dois anos de mandato. Os vídeos foram analisados a partir da técnica de análise de discurso de base francesa, que considera textos orais e escritos como discursos, e com o suporte da semiótica para a análise das imagens que acompanham a letra. A análise indica que os trabalhadores denunciam o rompimento do contrato psicológico estabelecido pela empresa, que se baseava na estabilidade do emprego. Os autores dos vídeos associam a empresa a uma figura feminina, ora mãe, ora amante, e o trabalho nela como algo que estava predestinado em sua vida. Eles demonstram o sentimento de abandono e traição, condizente com esse tipo de situação.

    Difficulties in emotion regulation are commonly reported among individuals with alcohol and drug addictions and contribute to the acquisition and maintenance of addictive behaviors. Alterations in neural processing of negative affective stimuli have further been demonstrated among individuals with addictions. However, it is unclear whether these alterations are a general feature of addictions or are a result of prolonged exposure to drugs-of-abuse. To test the hypothesis of altered negative affect processing independent of drug effects, this study assessed neural function among drug-naïve youth with a behavioral addiction-Internet gaming disorder (IGD). Fifty-six young adults (28 with IGD, 28 matched controls) participated in fMRI scanning during performance of a well-validated emotion regulation task. Between-group differences in neural activity during task performance were assessed using a whole-brain, mixed-effects ANOVA with correction for multiple comparisons at currently recommended thresholds (voxel-level pnegative affective cues, as well as during emotion regulation. Independent component analysis (ICA) further identified between-group differences in engagement of a fronto-cingulo-parietal network, involving decreased engagement in IGD youth relative to controls. Study findings are largely consistent with those from prior neuroimaging studies in substance-use disorders, thus raising the possibility that neural processing of negative affect may be blunted across drug and behavioral addictions independent of acute or chronic drug effects.Neuropsychopharmacology accepted article preview online, 20 November 2017. doi:10.1038/npp.2017.283.

Despite the wide use of internet, the potentials it has are sometimes unnoticed. While web-based dictionaries or thesaurus often serve as translators’ assistants and online Machine Translation issues become topics of many researches, other uses of internet related to translation may not be known by many. Internet can help disseminate newborn ideas, theories and findings worldwide to enhance translation theories. Besides, the contact between internet and translation generates new areas to examine. Internet also provides helping hand in the area of translation research. Researcher or anyone conducting research in the field of translation can find a range of research gaps as well as reference. Those who need group discussions to collect required data from informants, or researchers of the same interest coming from all over the world can meet and conduct Focus Group Discussion (FGD on virtual world. Furthermore, internet offers various forms of assistance for translation practitioners. The commonly used internet assistance consists of dictionaries, thesaurus and Machine Translations available on the internet. Other forms of aid provided by internet take form of parallel texts, images, and videos, which can be very helpful. Internet provides many things which can be utilized for the purpose of translation. Internet keeps on providing more as it develops from time to time in line with the development of technology. Internet awaits utilization of theorists, researchers, practitioners and those having concern on translation.

  13. A primer on theory-driven web scraping: Automatic extraction of big data from the Internet for use in psychological research.

    The term big data encompasses a wide range of approaches of collecting and analyzing data in ways that were not possible before the era of modern personal computing. One approach to big data of great potential to psychologists is web scraping, which involves the automated collection of information from webpages. Although web scraping can create massive big datasets with tens of thousands of variables, it can also be used to create modestly sized, more manageable datasets with tens of variables but hundreds of thousands of cases, well within the skillset of most psychologists to analyze, in a matter of hours. In this article, we demystify web scraping methods as currently used to examine research questions of interest to psychologists. First, we introduce an approach called theory-driven web scraping in which the choice to use web-based big data must follow substantive theory. Second, we introduce data source theories , a term used to describe the assumptions a researcher must make about a prospective big data source in order to meaningfully scrape data from it. Critically, researchers must derive specific hypotheses to be tested based upon their data source theory, and if these hypotheses are not empirically supported, plans to use that data source should be changed or eliminated. Third, we provide a case study and sample code in Python demonstrating how web scraping can be conducted to collect big data along with links to a web tutorial designed for psychologists. Fourth, we describe a 4-step process to be followed in web scraping projects. Fifth and finally, we discuss legal, practical and ethical concerns faced when conducting web scraping projects.

    The purposes of the internal monitoring, in general, are to verify and document that each worker is protected adequately against risks from radionuclide intakes and the protection complies with legal requirements. Therefore, an overall radiation protection programme, starts with an assessment to identify work situations in which there is a risk of internal contamination of workers and to quantify the likely intake of radioactive material and the resulting committed effective dose. As a part of a continuous improvement of the monitoring programme for occupationally exposed workers at IPEN, it is being developed a Web based system to access the internal dosimetry database. The system was implemented using Hypertext Preprocessor, PHP, and a PostgreSQL database. This system will introduce a new paradigm in the routine of the internal dosimetry service, providing a fast access to the information among the measurement laboratories staff, dose evaluation group and the radiation protection supervisor. The database maintains information about worker identification, physical and chemical characteristics of the radionuclide, type of monitoring, measurement data and the dose. Moreover, this information will be readily available to provide support for regulatory compliance and quality control requirements. (author)

    Full Text Available Abstract Background Chronic Fatigue Syndrome (CFS is increasingly recognized as a cause of disability and inactivity in adolescents in the Netherlands. CFS is characterized by unexplained fatigue lasting more than 6 months. Cognitive Behavioural Therapy (CBT has proven to be effective. However, CBT availability for adolescents with CFS is limited and requires special therapeutic skills not always readily available. An alternative to the face-to-face CBT is FITNET, a web-based therapeutic program designed specifically for adolescents diagnosed with CFS, and their parents. This new CBT approach appeals to the modern youth, who grow up with internet as their main source of information. A web-based program offers the opportunity to lower thresholds for the acceptance and realization of healthcare. This treatment can be activated at any chosen time. The communication between patient and therapist can elapse asynchronously. If effective, this web-based program would greatly increase the therapeutic accessibility. Methods/Design A randomized clinical trial is currently conducted. One-hundred-forty adolescents aged 12-18 years diagnosed with CFS will be recruited and randomized to one of two groups: FITNET or usual care. After 6 months, the usual care group will have access to the FITNET program. Outcomes will be assessed at baseline, post intervention, and at 6 months follow-up. Primary outcome measures are school presence, fatigue severity, and physical functioning. Discussion The FITNET study is the first randomized clinical trial which evaluates the effect of web-based CBT versus usual care in adolescents with CFS. The intervention is based on a theoretical existing model of CBT for patients with CFS. The results of this study will provide information about the possibility and efficacy of web-based CBT for adolescents with CFS and will reveal predictors of efficacy.

  10. SurveyWiz and factorWiz: JavaScript Web pages that make HTML forms for research on the Internet.

    Science.gov (United States)

    Birnbaum, M H

    2000-05-01

    SurveyWiz and factorWiz are Web pages that act as wizards to create HTML forms that enable one to collect data via the Web. SurveyWiz allows the user to enter survey questions or personality test items with a mixture of text boxes and scales of radio buttons. One can add demographic questions of age, sex, education, and nationality with the push of a button. FactorWiz creates the HTML for within-subjects, two-factor designs as large as 9 x 9, or higher order factorial designs up to 81 cells. The user enters levels of the row and column factors, which can be text, images, or other multimedia. FactorWiz generates the stimulus combinations, randomizes their order, and creates the page. In both programs HTML is displayed in a window, and the user copies it to a text editor to save it. When uploaded to a Web server and supported by a CGI script, the created Web pages allow data to be collected, coded, and saved on the server. These programs are intended to assist researchers and students in quickly creating studies that can be administered via the Web.

    Aim of the study: Is it possible to use the Internet as a secure media for transport of telemedicine? Which risks exist for routine use? In this article state of the art methods of security were analysed. Telemedicine in the Internet has severe risks, because patient data and hospital data of a secure Intranet can be manipulated by connecting it to the Web. Conclusions: Establishing of a firewall and the introduction of HPC (Health Professional Card) are minimizing the risk of un-authorized access to the hospital server. HPC allows good safety with digital signature and authentication of host and client of medical data. For secure e-mail PGP (Pretty Good Privacy) is easy to use as a standard protocol. Planning all activities exactly as well as following legal regulations are important requisites for reduction of safety risks in Internet. (orig.) [German] Ziele der Studie und Analyse: Es sollten die Fragen beantwortet werden, ob es moeglich ist, das Internet als sicheres Uebermittlungsmedium fuer Telemedizin zu nutzen und welche Sicherheitsrisiken bestehen. Dazu wurden die gaengigen Sicherheitsmethoden analysiert. Telemedizin im Internet ist mit Sicherheitsrisiken behaftet, die durch die Oeffnung eines Intranets mit der Moeglichkeit zur unberechtigten Manipulation von aussen bedingt sind. Schlussfolgerung: Diese Sicherheitsrisiken koennen durch eine Firewall weitgehend unterbunden werden. Chipkarten wie die Health professional card ermoeglichen eine hohe Sicherheit bei digitaler Signatur und sicherer Authentifikation der Sender und Empfaenger von Daten im Internet. Auch Standards wie Pretty good privacy sind inzwischen fuer sichere e-mails einfach einzusetzen. Wichtige Voraussetzung fuer die Reduktion von Sicherheitsrisiken ist unter Beruecksichtigung der gesetzlichen Vorgaben die exakte Planung aller Aktivitaeten im Internet, bei denen medizinische Patientendaten versandt werden sollen, in einem Team aus Aerzten und Informatikern.

    Full Text Available Il Web è diventato davvero uno specchio per vanitosi? Giovani e adulti si cimentano in bravate, oscenità, per poi filmarsi e pubblicare il video. Anche il suicidio può venire facilitato dal Web: mentre in Giappone si sottoscrivono patti di morte con sconosciuti, in occidente ci si toglie la vita di fronte la webcam nella solitudine della propria stanza. Se nel paese orientale le persone cercano di fuggire da una società che le rifiuta, che accetta solo la maschera che mostrano in pubblico e non il volto che essa cela, in occidente si scopre la mancanza di valore per la vita. Non essendo capaci di raccontarsi, scelgono di mostrare la propria immagine, l’unica cosa che è permesso loro gestire. Da spettatori, ora pretendono la parte dei protagonisti e la loro è una voglia di urlare parole rimaste soffocate per tanto tempo. Cercano di colpire gli occhi, costringendo il mondo ad assistere alla loro decisione definitiva. Le Web est-il vraiment devenu un miroir pour les vaniteux? Jeunes et adultes se livrent à des bravades, des obscénités, qu’ils filment dans la perspective de publier la vidéo. Ainsi, même le suicide peut être facilité par le Web. Alors qu’au Japon on signe des pactes de mort avec des inconnus, en Occident on s’ôte la vie devant une webcam, dans la solitude de son domicile. Si en Orient il s’agit d’une tentative de fuir une société qui refuse, qui accepte seulement le masque que l’on montre en public et non pas le visage qu’il cache, à l’Ouest nous découvrons le manque de valeur accordée à la vie. N'étant pas capables de se raconter, les gens choisissent de mettre en scène leur propre image, la seule chose qu’il leur est donné de gérer. Hier spectateurs, ils exigent aujourd’hui de devenir des protagonistes, et ainsi de pouvoir hurler des mots qui ont si longtemps été étouffés. Ils essaient de frapper les yeux, en obligeant le monde à assister à leur décision définitive.Is the Web

    2013-01-01

    Introduction: Informal and formal lifelong learning is essential at university and in the workplace. Apart from classical learning techniques, Web 2.0 tools can be used. It is controversial whether there is a so-called net generation amongst people under 30. Aims: To test the hypothesis that a net generation among students and young veterinarians exists. Methods: An online survey of students and veterinarians was conducted in the German-speaking countries which was advertised via online media and traditional print media. Results: 1780 people took part in the survey. Students and veterinarians have different usage patterns regarding social networks (91.9% vs. 69%) and IM (55.9% vs. 24.5%). All tools were predominantly used passively and in private, to a lesser extent also professionally and for studying. Outlook: The use of Web 2.0 tools is useful, however, teaching information and media skills, preparing codes of conduct for the internet and verification of user generated content is essential.

    This study evaluated the degree to which anabolic-androgenic steroids are proffered for sale over the Internet and how they are characterized on popular Web sites. Searches for specific steroid product labels (e.g., Dianabol) between March 2006 and June 2006 revealed that approximately half of the Web sites advocated their "safe" use, and roughly one third offered to sell them without prescriptions. The Web sites frequently presented misinformation about steroids and minimized their dangers. Less than 5% of the Web sites presented accurate health risk information about steroids or provided information to abusers seeking to discontinue their steroid use. Implications for education, prevention, treatment, and policy are discussed.

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

    The NASA Langley Research Center Science Directorate and Atmospheric Science Data Center have initiated a pilot program to utilize Geographic Information System (GIS) tools that enable, generate and store climatological averages using spatial queries and calculations in a spatial database resulting in greater accessibility of data for government agencies, industry and private sector individuals. The major objectives of this effort include the 1) Processing and reformulation of current data to be consistent with ESRI and openGIS tools, 2) Develop functions to improve capability and analysis that produce "on-the-fly" data products, extending these past the single location to regional and global scales. 3) Update the current web sites to enable both web-based and mobile application displays for optimization on mobile platforms, 4) Interact with user communities in government and industry to test formats and usage of optimization, and 5) develop a series of metrics that allow for monitoring of progressive performance. Significant project results will include the the development of Open Geospatial Consortium (OGC) compliant web services (WMS, WCS, WFS, WPS) that serve renewable energy and agricultural application products to users using GIS software and tools. Each data product and OGC service will be registered within ECHO, the Common Metadata Repository, the Geospatial Platform, and Data.gov to ensure the data are easily discoverable and provide data users with enhanced access to SSE data, parameters, services, and applications. This effort supports cross agency, cross organization, and interoperability of SSE data products and services by collaborating with DOI, NRCan, NREL, NCAR, and HOMER for requirements vetting and test bed users before making available to the wider public.

    Full Text Available This qualitative study examined an innovative methodology, combining screen capture technology and a retrospective think aloud, for exploring the use of Internet-based resources by elementary teachers. Pre-service and in-service teachers explored The Balanced Literacy Diet, a free, interactive, and evidenced-informed professional development website. As participants navigated through this complex site, each visual step was captured using Camtasia Studio, a screen recording computer software program developed by TechSmith. Immediately following their 10-minute exploration, participants revisited their online choices virtually and verbalized their thoughts while viewing their screen recording. Qualitative analysis confirmed the usefulness of the methodology and provided insights about the factors that motivate teachers to use professional development websites. Results of the analysis can contribute to the ongoing development of high quality online learning environments. Cette étude qualitative s’est penchée sur une méthodologie innovatrice combinant les technologies de saisie d’écran et la pensée rétrospective à voix haute pour l’exploration de l’utilisation des ressources dans Internet par les enseignants de l’élémentaire.

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    2012-01-01

    Internet addiction is defined as uncontrolled and harmful use of Internet, which manifests in three forms: gaming, various sexual activities and excessive use of emails, chats or SMS messaging. Several studies have found that abuse of alcohol and other substances, depression and other health problems are associated with Internet addiction. In boys and men depression may be more a consequence of the addiction than a cause for it. ADHD seems to be a significant background factor for developing the condition. Because it is almost impossible to lead a life without Internet and computers nowadays, it is unrealistic to aim towards full abstinence. Treatment has generally followed the guidelines adapted for pathological gambling.

    OBJECTIVE To determine whether access to health information via in-home Internet technology can positively influence empowerment among residents of a low-income urban community. DESIGN In-home Internet access and training were provided to volunteers, who, along with a comparison group, were interviewed prior to and 1 year after initiation of the program. Community-based participatory research methods were used to design and implement the intervention. SETTING A 57-block area on the West Side of Chicago. PATIENTS/PARTICIPANTS Twenty-five community residents completed all phases of the technology intervention. Thirty-five randomly selected neighbors of these residents served as the comparison group. INTERVENTIONS Members of the intervention group received Internet access via WebTV, training, technical support, and access to a community specific health-oriented web page during the course of the study. MEASUREMENTS AND MAIN RESULTS Intervention group members were similar to comparison group members in terms of empowerment at baseline. After receiving Internet access and training, empowerment related to health decision-making improved significantly in the intervention group. Similar changes did not occur in the comparison group. Affinity for and appreciation of information technology also increased in the intervention group but not in the comparison group. As a result, differences in attitudes toward technology increased between the 2 groups over time. CONCLUSIONS Using community-based participatory research methods, we found that Internet access to community-specific and general health information can lead to increased empowerment and appreciation of information technology. These benefits accrued among the intervention group but not among a random group of their neighbors. PMID:12848835

    Computers and the Internet provide researchers with new options in surveying. When using electronic surveys, several practical and methodological issues need to be considered such as whether the majority of the surveyed population has Internet access and whether an e-mail or a Web-based survey is most appropriate. Other important considerations relate to Internet security issues and, in international research, the possibility of language barriers. Despite these challenges, electronic surveys offer a promising alternative to conventional mail surveys.

    Precision medicine has resulted in increasing complexity in the treatment of cancer. Web-based educational materials can help address the needs of oncology health care professionals seeking to understand up-to-date treatment strategies. This study aimed to assess learning styles of oncology health care professionals and to determine whether learning style-tailored educational materials lead to enhanced learning. In all, 21,465 oncology health care professionals were invited by email to participate in the fully automated, parallel group study. Enrollment and follow-up occurred between July 13 and September 7, 2015. Self-enrolled participants took a learning style survey and were assigned to the intervention or control arm using concealed alternating allocation. Participants in the intervention group viewed educational materials consistent with their preferences for learning (reading, listening, and/or watching); participants in the control group viewed educational materials typical of the My Cancer Genome website. Educational materials covered the topic of treatment of metastatic estrogen receptor-positive (ER+) breast cancer using cyclin-dependent kinases 4/6 (CDK4/6) inhibitors. Participant knowledge was assessed immediately before (pretest), immediately after (posttest), and 2 weeks after (follow-up test) review of the educational materials. Study statisticians were blinded to group assignment. A total of 751 participants enrolled in the study. Of these, 367 (48.9%) were allocated to the intervention arm and 384 (51.1%) were allocated to the control arm. Of those allocated to the intervention arm, 256 (69.8%) completed all assessments. Of those allocated to the control arm, 296 (77.1%) completed all assessments. An additional 12 participants were deemed ineligible and one withdrew. Of the 552 participants, 438 (79.3%) self-identified as multimodal learners. The intervention arm showed greater improvement in posttest score compared to the control group (0.4 points

    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.

    2004-03-01

    Internet is known to display a highly heterogeneous structure and complex fluctuations in its traffic dynamics. Congestion seems to be an inevitable result of user's behavior coupled to the network dynamics and it effects should be minimized by choosing appropriate routing strategies. But what are the requirements of routing depth in order to optimize the traffic flow? In this paper we analyse the behavior of Internet traffic with a topologically realistic spatial structure as described in a previous study [S.-H. Yook et al., Proc. Natl Acad. Sci. USA 99, 13382 (2002)]. The model involves self-regulation of packet generation and different levels of routing depth. It is shown that it reproduces the relevant key, statistical features of Internet's traffic. Moreover, we also report the existence of a critical path horizon defining a transition from low-efficient traffic to highly efficient flow. This transition is actually a direct consequence of the web's small world architecture exploited by the routing algorithm. Once routing tables reach the network diameter, the traffic experiences a sudden transition from a low-efficient to a highly-efficient behavior. It is conjectured that routing policies might have spontaneously reached such a compromise in a distributed manner. Internet would thus be operating close to such critical path horizon.

Três médicos com experiência em revisões sistemáticas e duas experts em comunicação com experiência na busca de dados nas ferramentas da Internet realizaram este estudo. RESULTADOS: Os dados da revisão sistemática mostraram algumas diferenças daqueles que podem ser obtidos em websites de alto acesso. CONCLUSÃO: Estudos com dados baseado em evidência, realizados sob criteriosas regras válidas para revisão sistemática e meta-análise devem ser disponibilizados de forma aberta, ou seja, permitindo acesso sem pagamento de taxas, fazendo com que o conhecimento de assuntos de grande interesse a profissionais de saúde e pacientes se globalize.

  20. Drugs, the Internet and change.

    Science.gov (United States)

    Walsh, Charlotte

    2011-01-01

    This article investigates the symbiotic relationship between drugs and the Internet, focusing (though not exclusively) on psychedelics. Programming on psychedelics in Silicon Valley from the 1960s to date is detailed, as are the twinned conceptualizations of drugs as a technology and technology as a drug. The correlation between drugs, the Internet, and consumerism is explored: the Internet is a medium through which "white," "grey" and "black" drug markets flourish. Thus, this article details the burgeoning online trades in pharmaceuticals, recreational, and "life-style" drugs that turn the Internet into a veritable candy store. Drug forums transmogrify into street corners, threatening the continued existence of the current system of global prohibition. However, it is arguably the use of the Web as an information source that may offer the greatest challenge to the incumbent paradigm, with experiential discourses offering alternatives to the hegemonic narrative, as the relationships between drugs, those who sell drugs and drug takers are reconfigured online.

    Internet biosurveillance utilizes unstructured data from diverse Web-based sources to provide early warning and situational awareness of public health threats. The scope of source coverage ranges from local based media in the vernacular to international media in widely read languages. Internet biosurveillance is a timely modality available to government and public health officials, health care workers, and the public and private sector, serving as a real-time complementary approach to traditional indicator-based public health disease surveillance methods. Internet biosurveillance also supports the broader activity of epidemic intelligence. This review covers the current state of the field of Internet biosurveillance and provides a perspective on the future of the field.

Este artigo é também um contributo teórico e concetual sobre esta problemática e simultaneamente um contributo para as empresas e gestores pelo facto de dar a conhecer os resultados de um estudo online, de tipo quantitativo, baseado numa amostra de 206 quadros empresariais portugueses que responderam a um questionário nas redes sociais facebook, Linkedin e Twitter, de vinte a vinte e sete de maio de 2013. O objetivo da pesquisa foi analisar comparativamente os métodos de marcação de hotéis em business-to-business (B2B com o intuito de medir a importância da internet nestes mercados em Portugal. Recorreu-se à análise descritiva e aplicação de testes estatísticos para facilitar a interpretação dos dados recolhidos. Os resultados mostram que a proporção de marcação de hotéis, em viagens de negócios, preferencialmente através da internet é a mais elevada das opções possíveis. Por outro lado, antes de efetuarem uma compra recorrem com mais frequência a motores de busca e sites de hotéis. No entanto, os resultados  não confirmam que a internet seja o método preferencial em mercados B2B.

    Web applications became most popular medium in the Internet. Popularity, easiness of web application frameworks together with careless development results in high number of vulnerabilities and attacks. There are several types of attacks possible because of improper input validation. SQL injection is ability to execute arbitrary SQL queries in a database through an existing application. Cross-site scripting is the vulnerability which allows malicious web users to inject code into the web pages viewed by other users. Cross-Site Request Forgery (CSRF) is an attack that tricks the victim into loading a page that contains malicious request. Web spam in blogs. There are several techniques to mitigate attacks. Most important are web application strong design, correct input validation, defined data types for each field and parameterized statements in SQL queries. Server hardening with firewall, modern security policies systems and safe web framework interpreter configuration are essential. It is advised to keep proper security level on client side, keep updated software and install personal web firewalls or IDS/IPS systems. Good habits are logging out from services just after finishing work and using even separate web browser for most important sites, like e-banking.

    In an era when social media sites like YouTube, Facebook, and Twitter dominate the popular press, many surgeons overlook the foundational tactics and strategies necessary for long-term practice development and lead generation on the Internet. This article analyzes common errors made by surgeons during the development and implementation of Web site projects, focusing on the areas of strategy development; domain name identification; site plan creation; design considerations; content development; vendor selection; and launch, promotion, and staff training. The article emphasizes that, because the Web site remains the foundation of a surgeon's branding message, minimizing errors during development and construction is critical, particularly in highly competitive or saturated markets, for today's facial plastic surgery practice.

    2002-01-01

    Internet is one of information technologies marking the transition from the second to the third millennium. The present role and expansion of Internet in medicine and healthcare is reviewed together with the perspective of further development. The beginning and initial expansion of the use of Internet in medicine are described. The World Wide Web (WWW or Web) is recognized as a major reason for this expansion, reaching a state described as a Web-pandemic. The rapid increase of the number of papers dealing with Internet in medical literature is presented as well as the appearance of several journals dedicated to Internet in medicine. First specialized symposia, among them MEDNET world conferences, are noted. First uses of Internet in medicine comprised databases, discussion groups, electronic newsletters, software archives and online public access catalogues. The appearance of the Web has led to a significant improvement of the Internet use in medicine, which is reflected in an exponential increase in the number of publications. It is noted that Internet allows "to do old things in new ways", but also "to do new things". It has become clear that the information revolution evoked by the internet shall leave a deep trace in medicine, as health information has become accessible to the public and ceased to be in exclusive control of health professionals. New medical fields--telemedicine and cybermedicine--appeared as the result of the development and global expansion of information and communication technologies, with cybermedicine dealing more specifically with the use of Internet. The advantages and disadvantages of cybermedicine are discussed, and major problems related to the quality of health information are highlighted. Several systems for quality criteria of health related Web-sites are described, indicating that Websites have to conform with the quality criteria such as transparency and honesty, accountability, privacy and data protection, currency

    The Internet Process Addiction Test (IPAT) was created to screen for potential addictive behaviors that could be facilitated by the internet. The IPAT was created with the mindset that the term "Internet addiction" is structurally problematic, as the Internet is simply the medium that one uses to access various addictive processes. The role of the internet in facilitating addictions, however, cannot be minimized. A new screening tool that effectively directed researchers and clinicians to the specific processes facilitated by the internet would therefore be useful. This study shows that the Internet Process Addiction Test (IPAT) demonstrates good validity and reliability. Four addictive processes were effectively screened for with the IPAT: Online video game playing, online social networking, online sexual activity, and web surfing. Implications for further research and limitations of the study are discussed.

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    2015-09-01

    Internet technologies have made a rapid progress, bringing convenience to daily life. On the other hand, internet use disorder and internet addiction (IA) have become reportedly serious health and social problems. In 2013, internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM-5. Existing epidemiological studies by questionnaire methods have reported that the prevalence of IA ranges between 2.8% and 9.9% among youths in Japan. Attention deficit hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders with IA. Some psychotherapies (e.g., cognitive behavioral therapy, motivational interviewing) and medical treatments (e.g., antidepressant drugs, methylphenidate) for comorbid mental disorders as well as rehabilitation (e.g., treatment camp) are effective for IA remission. However, some serious cases of IA may be difficult to treat, and prevention is very important. In future, the prevention, rehabilitations and treatments for IA will be more required in Japan.

    Science.gov (United States)

    Daneback, Kristian; Månsson, Sven-Axel; Ross, Michael W

    2012-08-01

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

    fatores que incidem na aceitação pelo consumidor final de um novo canal de distribuição, o presente artigo avalia a importância da conveniência, da norma subjetiva, da utilidade e da facilidade de uso percebida na intenção da compra on-line por parte do consumidor. O estudo dessas variáveis é realizado no contexto dos fundamentos dos Modelos de Aceitação de Tecnologia - TAM e da Teoria do Comportamento Planejado, cuja base teórica é a Teoria da Ação Racional, a partir de um modelo de relações causais. Para alcançar tal objetivo foi realizada, na Espanha, uma pesquisa on-line com internautas, durante os meses de dezembro de 2007 a janeiro de 2008. O tamanho da amostra foi de 190 internautas. Para testar o modelo causal proposto pela pesquisa foi utilizado o método PLS, especialmente adequado para trabalhar com escalas formativas e para pesquisas de campo por TAM. Os resultados obtidos revelaram que conveniência constitui a influência mais importante sobre o uso da internet como canal de compra, bem como um dos fatores mais importantes que, somados às normas subjetivas, determinam as intenções de compra pela Internet. Esses resultados são coerentes com os encontrados em trabalhos realizados anteriormente em destacada literatura, revelando como a conveniência é o principal fator de motivação para as compras on-line. A partir destes dados foi possível propor diversas recomendações para melhorar a gestão comercial on-line para empresas do setor.ABSTRACTWith the aim of studying those factors affecting the acceptance of a new distribution channel by the final consumer, we have analyzed the importance of acquiring by the convenience, subjective norm, usefulness and perceived ease of use on intention to buy on-line by the end user.

    The trend in most systems is that they are connected through the Internet. Traditional Supervisory Control and Data Acquisition Systems (SCADA) is connected only in a limited private network. SCADA is considered a critical infrastructure, and connecting to the internet is putting the society on jeopardy, some operators hold back on connecting it to the internet. But since the internet Supervisory Control and Data Acquisition Systems (SCADA) facility has brought a lot of advantages in terms of control, data viewing and generation. Along with these advantages, are security issues regarding web SCADA, operators are pushed to connect Supervisory Control and Data Acquisition Systems (SCADA) through the internet. Because of this, many issues regarding security surfaced. In this paper, we discuss web SCADA and the issues regarding security. As a countermeasure, a web SCADA security solution using crossed-crypto-scheme is proposed to be used in the communication of SCADA components.

    Web-based interventions have received attention for substance abuse treatment. Few studies have examined Internet use among substance users. Internet-use data were examined for 66 participants screened to participate in behavioral pharmacology studies. A majority of active cocaine users reported regular Internet use. Demographic profiles generally did not impact Internet use, but Internet users were more likely to be younger and report other drug use. Active cocaine users have similar rates of Internet access as the general population. Our findings contribute to the limited data on Internet use in active drug users by demonstrating Internet access in cocaine-using populations, supporting the use of this medium to conduct research and clinical interventions. © American Academy of Addiction Psychiatry.

    In 1990, the first monochrome print-on-demand (POD) systems wee successfully brought to market. Subsequent color versions have been less successful, in my view mostly because they require a different workflow than traditional systems and the highly skilled specialists have not been trained. This hypothesis is based on the observation that direct-to-plate systems for short run printing, which do not require a new workflow, are quite successful in the market place. The internet and the World Wide Web are the enabling technologies that are fostering a new print model that is very likely to replace color POD before the latter can establish itself. In this model the consumers locate the material they desire from a contents provider, pay through a digital cash clearinghouse, and print the material at their own cost on their local printer. All the basic technologies for this model are in place; the main challenge is to make the workflow sufficiently robust for individual use.

This server is available by means of an Internet browser with an interpreter of the Java programming language. We have used Java technology for remote control this full-motorized telemicroscope. The Java program for microscope control is automatically downloaded and started when the user selects the Web site of the corresponding microscope server with his Internet browser. At the client's side, there is no need for any additional software except for what is included in Netscape Navigator 3.0, Microsoft Explorer 3.0 or its later versions. Our remote microscope can be remotely controlled from any place in the world through the Internet. The user can move the microscope stage, change the magnification or can execute any other microscope operations by pressing the related buttons of the downloaded telemicroscopy client program. The microscope server receives the commands from the client program, executes the operation on the microscope and after every new command distributes the next microscope image to the connected telemicroscopy clients. There are also software modules which allow marking a field of interest in the image and discuss. Every Internet user can control the remote microscope and discuss the images with others who have direct access to the Internet on-line, or are connected by modem or ISDN. The quality of the transferred microscopic images and response time is sufficient for practical use. No complicated installation processes are necessary and the system is easy to use. The system design makes every pathologist, who is the Internet user, to be a possible consultant.

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004). In addition, drug use may predict a high risk for internet addiction (OR=2.591, pinternet addiction have vulnerability for addictive behaviors, co-morbid substance abuse should be evaluated and, if found, treated in adolescents with internet addiction.

    Each day, more than 12.5 million health-related computer searches are conducted on the World Wide Web. Based on a meta-analysis of 24 published surveys, the author estimates that in the developed world, about 39% of persons with cancer are using the Internet, and approximately 2.3 million persons living with cancer worldwide are online. In addition, 15% to 20% of persons with cancer use the Internet "indirectly" through family and friends. Based on a comprehensive review of the literature, the available evidence on how persons with cancer are using the Internet and the effect of Internet use on persons with cancer is summarized. The author distinguishes four areas of Internet use: communication (electronic mail), community (virtual support groups), content (health information on the World Wide Web), and e-commerce. A conceptual framework summarizing the factors involved in a possible link between Internet use and cancer outcomes is presented, and future areas for research are highlighted.

  15. Maintaining Web Cache Coherency

    Full Text Available Document coherency is a challenging problem for Web caching. Once the documents are cached throughout the Internet, it is often difficult to keep them coherent with the origin document without generating a new traffic that could increase the traffic on the international backbone and overload the popular servers. Several solutions have been proposed to solve this problem, among them two categories have been widely discussed: the strong document coherency and the weak document coherency. The cost and the efficiency of the two categories are still a controversial issue, while in some studies the strong coherency is far too expensive to be used in the Web context, in other studies it could be maintained at a low cost. The accuracy of these analysis is depending very much on how the document updating process is approximated. In this study, we compare some of the coherence methods proposed for Web caching. Among other points, we study the side effects of these methods on the Internet traffic. The ultimate goal is to study the cache behavior under several conditions, which will cover some of the factors that play an important role in the Web cache performance evaluation and quantify their impact on the simulation accuracy. The results presented in this study show indeed some differences in the outcome of the simulation of a Web cache depending on the workload being used, and the probability distribution used to approximate updates on the cached documents. Each experiment shows two case studies that outline the impact of the considered parameter on the performance of the cache.
