Patients are increasingly using the Internet (43% in 2000 vs. 70% in 2006) to obtain health information, but is there a difference in the ability of urban and suburban emergency department (ED) customers to access the Internet? To assess computer and Internet resources available to and used by people waiting to be seen in an urban ED and a suburban ED. Individuals waiting in the ED were asked survey questions covering demographics, type of insurance, access to a primary care provider, reason for their ED visit, computer access, and ability to access the Internet for health-related matters. There were 304 individuals who participated, 185 in the urban ED and 119 in the suburban ED. Urban subjects were more likely than suburban to be women, black, have low household income, and were less likely to have insurance. The groups were similar in regard to average age, education, and having a primary care physician. Suburban respondents were more likely to own a computer, but the majority in both groups had access to computers and the Internet. Their frequency of accessing the Internet was similar, as were their reasons for using it. Individuals from the urban ED were less willing to schedule appointments via the Internet but more willing to contact their health care provider via e-mail. The groups were equally willing to use the Internet to fill prescriptions and view laboratory results. Urban and suburban ED customers had similar access to the Internet. Both groups were willing to use the Internet to access personal health information. Copyright © 2012 Elsevier Inc. All rights reserved.

Approximate Networking for Universal Internet Access

Full Text Available Despite the best efforts of networking researchers and practitioners, an ideal Internet experience is inaccessible to an overwhelming majority of people the world over, mainly due to the lack of cost-efficient ways of provisioning high-performance, global Internet. In this paper, we argue that instead of an exclusive focus on a utopian goal of universally accessible “ideal networking” (in which we have a high throughput and quality of service as well as low latency and congestion, we should consider providing “approximate networking” through the adoption of context-appropriate trade-offs. In this regard, we propose to leverage the advances in the emerging trend of “approximate computing” that rely on relaxing the bounds of precise/exact computing to provide new opportunities for improving the area, power, and performance efficiency of systems by orders of magnitude by embracing output errors in resilient applications. Furthermore, we propose to extend the dimensions of approximate computing towards various knobs available at network layers. Approximate networking can be used to provision “Global Access to the Internet for All” (GAIA in a pragmatically tiered fashion, in which different users around the world are provided a different context-appropriate (but still contextually functional Internet experience.

How Much Is Too Much to Pay for Internet Access? A Behavioral Economic Analysis of Internet Use.

Science.gov (United States)

Broadbent, Julie; Dakki, Michelle A

2015-08-01

The popularity of online recreational activities, such as social networking, has dramatically increased the amount of time spent on the Internet. Excessive or inappropriate use of the Internet can result in serious adverse consequences. The current study used a behavioral economic task to determine if the amount of time spent online by problematic and nonproblematic users can be modified by price. The Internet Purchase Task was used to determine how much time undergraduate students (N=233) would spend online at 13 different prices. Despite high demand for Internet access when access was free, time spent online by both problematic and nonproblematic users decreased dramatically, even at low prices. These results suggest that the amount of time spent online may be modified by having a tangible cost associated with use, whereas having free access to the Internet may encourage excessive, problematic use.

Ferguson, Amanda M; McLean, David; Risko, Evan F

2015-12-01

Recent technological advances have given rise to an information-gathering tool unparalleled by any in human history-the Internet. Understanding how access to such a powerful informational tool influences how we think represents an important question for psychological science. In the present investigation we examined the impact of access to the Internet on the metacognitive processes that govern our decisions about what we "know" and "don't know." Results demonstrated that access to the Internet influenced individuals' willingness to volunteer answers, which led to fewer correct answers overall but greater accuracy when an answer was offered. Critically, access to the Internet also influenced feeling-of-knowing, and this accounted for some (but not all) of the effect on willingness to volunteer answers. These findings demonstrate that access to the Internet can influence metacognitive processes, and contribute novel insights into the operation of the transactive memory system formed by people and the Internet.

2013-01-01

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

Antonio J. Jara

2014-01-01

Full Text Available Emerging Internet of Things (IoT/Machine-to-Machine (M2M systems require a transparent access to information and services through a seamless integration into the Future Internet. This integration exploits infrastructure and services found on the Internet by the IoT. On the one hand, the so-called Web of Things aims for direct Web connectivity by pushing its technology down to devices and smart things. On the other hand, the current and Future Internet offer stable, scalable, extensive, and tested protocols for node and service discovery, mobility, security, and auto-configuration, which are also required for the IoT. In order to integrate the IoT into the Internet, this work adapts, extends, and bridges using IPv6 the existing IoT building blocks (such as solutions from IEEE 802.15.4, BT-LE, RFID while maintaining backwards compatibility with legacy networked embedded systems from building and industrial automation. Specifically, this work presents an extended Internet stack with a set of adaptation layers from non-IP towards the IPv6-based network layer in order to enable homogeneous access for applications and services.

Using Metadata to Build Geographic Information Sharing Environment on Internet

1999-12-01

Full Text Available Internet provides a convenient environment to share geographic information. Web GIS (Geographic Information System even provides users a direct access environment to geographic databases through Internet. However, the complexity of geographic data makes it difficult for users to understand the real content and the limitation of geographic information. In some cases, users may misuse the geographic data and make wrong decisions. Meanwhile, geographic data are distributed across various government agencies, academic institutes, and private organizations, which make it even more difficult for users to fully understand the content of these complex data. To overcome these difficulties, this research uses metadata as a guiding mechanism for users to fully understand the content and the limitation of geographic data. We introduce three metadata standards commonly used for geographic data and metadata authoring tools available in the US. We also review the current development of geographic metadata standard in Taiwan. Two metadata authoring tools are developed in this research, which will enable users to build their own geographic metadata easily.[Article content in Chinese

Mobile access to the Internet: from personal bubble to satellites

Science.gov (United States)

Gerla, Mario

2001-10-01

Mobile, wireless access and networking has emerged in the last few years as one of the most important directions of Internet growth. The popularity of mobile, and, more generally, nomadic Internet access is due to many enabling factors including: (a) emergence of meaningful applications tailored to the individual on the move; (b) small form factor and long battery life; (c) efficient middleware designed to support mobility; and, (d) efficient wireless networking technologies. A key player in the mobile Internet access is the nomad, i.e. the individual equipped with various computing and I/O gadgets (cellular phone, earphones, GPS navigator, palm pilot, beeper, portable scanner, digital camera, etc.). These devices form his/her Personal Area Network or PAN or personal bubble. The connectivity within the bubble is wireless (using for example a low cost, low power wireless LAN such as Bluetooth). The bubble can expand and contract dynamically depending on needs. It may temporarily include sensors and actuators as the nomad walks into a new environment. In this paper, we identify the need for the interconnection of the PAN with other wireless networks in order to achieve costeffective mobile access to the Internet. We will overview some key networking technologies required to support the PAN (eg, Bluetooth). We will also discuss an emerging technology, Ad Hoc wireless networking which is the natural complement of the PAN in sparsely populated areas. Finally, we will identify the need for intelligent routers to assist the mobile user in the selection of the best Internet access strategy.

Youth experiencing homelessness are at a risk for a variety of adverse outcomes. Given the widespread use of the internet and social media, these new technologies may be used to address their needs and for outreach purposes. However, little is known about how this group uses these resources. This study investigated how homeless adolescents use these technologies for general and health-related purposes, whether the scope of their use changes with housing status, and their interest in a website dedicated to youth experiencing homelessness. A convenience sample of youth aged 18 to 21 years was recruited from a youth-specific homeless shelter. All participants completed a 47-item survey, with 10 individuals completing a semistructured interview. Descriptive statistics, exact testing, logistic regression, and generalized estimating equation modeling was performed for quantitative data analysis. Interviews were transcribed verbatim, and NVivo 10 (QSR International) was employed to facilitate double coding and thematic analysis. A total of 87 participants completed the survey with a mean age of 19.4 (SD 1.1) years. While experiencing homelessness, 56% (49/87) accessed the internet at least once a day, with 86% (75/87) accessing once a week. Access to a smartphone was associated with a 3.03 greater odds of accessing the internet and was the most frequently used device (66% of participants, 57/87). While experiencing homelessness, subjects reported a 68% decreased odds in internet access frequency (odds ratio [OR] 0.32, Psocial media use (OR 0.13, P=.01). Ten participants completed the semistructured interview. Several themes were identified, including (1) changes in internet behaviors while experiencing homelessness, (2) health status as a major concern and reason for Internet use, and (3) interest in a website dedicated to youth experiencing homelessness. While experiencing homelessness, participants indicated their behaviors were more goal-oriented and less focused on

Background The internet is increasingly being used worldwide in imparting medical education and improving its delivery. It has become an important tool for healthcare professionals training but the data on its use by medical students in developing countries is lacking with no study on the subject from Pakistan. This study was, therefore, carried out with an aim to evaluate the pattern of internet access and utilization by medical students in Pakistan. Methods A structured pre-tested questionnaire was administered to a group of 750 medical students in clinical years studying at various public and private medical colleges in Lahore. The questions were related to patterns of internet access, purpose of use and self reported confidence in performing various internet related tasks, use of health related websites to supplement learning and the problems faced by students in using internet at the institution. Results A total of 532 medical students (70.9%) returned the questionnaire. The mean age of study participants was 21.04 years (SD 1.96 years). Majority of the respondents (84.0%) reported experience with internet use. About half of the students (42.1%) were using internet occasionally with 23.1%, 20.9% and 13.9% doing so frequently, regularly and rarely respectively. About two third of the students (61.0%) stated that they use internet for both academic and professional activities. Most of the participants preferred to use internet at home (70.5%). Self reported ability to search for required article from PubMed and PakMedinet was reported by only 34.0% of the entire sample. Students were moderately confident in performing various internet related tasks including downloading medical books from internet, searching internet for classification of diseases and downloading full text article. Health related websites were being accessed by 55.1% students to supplement their learning process. Lack of time, inadequate number of available computers and lack of support from

The purpose of this study was to determine the feasibility of archiving radiographic images from Vietnam era conflict casualties into a personal computer-based electronic database of text and images and displaying the data using an Internet-accessible database for preservation and educational purposes. Thirty-two patient cases were selected at random from a pool of 1,000 autopsy reports in which radiographs were available. A total of 74 radiographs from these cases were digitized using a commercial image scanner and then uploaded into an Internet accessible database. The quality of the digitized images was assessed by administering an image-based test to a group of 12 medical students. No statistically significant (p > 0.05) differences were found between test scores when using the original radiographs versus using the digitized radiographs on the Internet-accessible database. An Internet-accessible database is capable of effectively archiving Vietnam era casualty radiographs for educational purposes.

The Internet of Things (IoT) refers to the paradigm of physical and virtual “things” that communicate and collaborate over the Internet, with minimal or no human intervention. There are multiple ways in which an IoT device can be connected to the Internet. Cellular technologies are seen as viable...... candidates in this respect, due to their maturity, worldwide availability and the use of reserved spectrum. However, current cellular systems are not well-equipped to efficiently and reliably support IoT traffic, particularly in the radio access part, as they are designed for low number of high......-rate connections and not for high number of low-rate IoT connections. In this chapter we outline the main features of the IoT traffic types, review operation of the current cellular access and provide some guidelines how to address its shortcomings and evolve it in order to support IoT services.

Prescription for trouble: Medicare Part D and patterns of computer and internet access among the elderly.

Science.gov (United States)

Wright, David W; Hill, Twyla J

2009-01-01

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 specifically encourages Medicare enrollees to use the Internet to obtain information regarding the new prescription drug insurance plans and to enroll in a plan. This reliance on computer technology and the Internet leads to practical questions regarding implementation of the insurance coverage. For example, it seems unlikely that all Medicare enrollees have access to computers and the Internet or that they are all computer literate. This study uses the 2003 Current Population Survey to examine the effects of disability and income on computer access and Internet use among the elderly. Internet access declines with age and is exacerbated by disabilities. Also, decreases in income lead to decreases in computer ownership and use. Therefore, providing prescription drug coverage primarily through the Internet seems likely to maintain or increase stratification of access to health care, especially for low-income, disabled elderly, who are also a group most in need of health care access.

Accessibility to public environment is the human right and basic need of each citizen and is one of the fundamental considerations for urban planning. The aim of this study is to determine the compliance of public buildings in central business districts (CBD) of Istanbul, Turkey, to wheelchair accessibility to the guidelines of the instrument and identify architectural barriers faced by wheelchair users. This is a descriptive study of 26 public buildings in CBD of Istanbul. The instrument used is the adapted Useh, Moyo and Munyonga questionnaire to collect the data from direct observation and measurement. Descriptive statistics of simple percentages and means are used to explain the compliance to the guidelines of the instrument and wheelchair accessibility. The descriptive survey results indicate that wheelchair users experience many accessibility problems in public environment of the most urbanised city (cultural capital of Europe in 2010) in a developing country. It is found that the major architectural barrier is the public transportation items with the lowest mean compliance (25%). Beside this, the most compliant to the instrument is entrance to building items with 79% as mean percentage. It is also found that there is an intention to improve accessibility when building construction period is investigated. This article describes the example of the compliance of public buildings accessibility when the country has legislation, but lacking regulations about accessibility for the wheelchair users.

Internet access and use by COPD patients in the National Emphysema/COPD Association Survey

Science.gov (United States)

2014-01-01

Background Technology offers opportunities to improve healthcare, but little is known about Internet use by COPD patients. We tested two hypotheses: Internet access is associated with socio-demographic disparities and frequency of use is related to perceived needs. Methods We analyzed data from a 2007–2008 national convenience sample survey of COPD patients to determine the relationship between Internet access and frequency of use with demographics, socio-economic status, COPD severity, and satisfaction with healthcare. Results Among survey respondents (response rate 7.2%; n = 914, 59.1% women, mean age 71.2 years), 34.2% reported lack of Internet access, and an additional 49% had access but used the Internet less than weekly. Multivariate models showed association between lack of access and older age (OR 1.10, 95% CI 1.07, 1.13), lower income (income below $30,000 OR 2.47, 95% CI 1.63, 3.73), less education (high school highest attainment OR 2.30, 95% CI 1.54, 3.45), comorbid arthritis or mobility-related disease (OR 1.56, 95% CI 1.05, 2.34). More frequent use (at least weekly) was associated with younger age (OR 0.95, 95% CI 0.93, 0.98), absence of cardiovascular disease (OR 0.48, 95% CI 0.29, 0.78), but with perception of needs insufficiently met by the healthcare system, including diagnostic delay (OR 1.72, 95% CI 1.06, 2.78), feeling treated poorly (OR 2.46, 95% CI 1.15, 5.24), insufficient physician time (OR 2.29, 95% CI 1.02, 5.13), and feeling their physician did not listen (OR 3.14, 95% CI 1.42, 6.95). Conclusions An analysis of the characteristics associated with Internet access and use among COPD patients identified two different patient populations. Lack of Internet access was a marker of socioeconomic disparity and mobility-associated diseases, while frequent Internet use was associated with less somatic disease but dissatisfaction with care.

2010-01-01

Full Text Available In an intermittently connected environment, access points are sparsely distributed throughout an area. As mobile users travel along the roadway, they can opportunistically connect, albeit temporarily, to roadside 802.11 (Wi-Fi APs for Internet access. Net-working characteristics of vehicular Internet access in an intermittently connected envi ronment face numerous challenges, such as short periods of connectivity and unpredictable connection times. To meet these challenges, we propose an Access Point Report (APR protocol where mobile stations opportunistically collaborate by broadcasting an APR to other mobile stations to fully utilize the short-lived connection periods. APR can optimize the use of short connection periods by minimizing the scanning delay and also act as a hint that enables mobile users to predict when connection can be established.

Communication inequalities deepen health disparities even when internet access is achieved. The goal of this study is to understand how a range of barriers may inhibit individuals from low socioeconomic position (SEP) from engaging with online health information even when it is freely available. Detailed data were collected from 118 low-SEP individuals from a randomized controlled trial providing internet access. Measures triangulated the health-seeking experience through internet use tracked in real-time, call log data, and self-reported barriers. Negative binomial regression models were fitted with technology and perceived predictors, and our outcome, health information seeking, and then stratified by medical status. Participants experienced a median of two computer issues (median 6 days) and two internet issues (median 6.5 days). Duration of internet problems was associated with a decrease in the rate of internet health information seeking by a factor of 0.990 (P = .03) for each additional day. Participants with a medical problem who were frustrated in their search for health information had half the rate of health information seeking of those who were not frustrated (incidence rate ratio = 0.395, P = .030). Despite IT support, participants still experienced internet connectivity issues that negatively impacted their health information seeking. Frustration in their search to find information may serve as an additional barrier to those who have medical issues. After initial internet access, a second-level digital divide emerged due to connectivity issues, highlighting the need to understand the complex network of barriers experienced by low-SEP internet users. © The Author 2016.

For lack of better resources, the general lowering periods in irregularly occupied buildings often are reduced to a minimum or the adjustment of the operating time is completely missing. In order to adjust the operating time optimally to the actual busy time, an internet-based booking system has been developed, which allows users to register a room assignment online. This booking system is linked with the building service facilities. This ensure the optimal setting of the lowering periods and therefore allows saving energy. The technical implementation resulted from a programmable logic controller (PLC) that can be accessed via a web browser. Temperature offset boxes have been added as interface between the PLC and the existing facilities in order that the system is applicable in existing buildings too. The booking system has been installed in two test objects and has also been successfully tested with the responsible staff (caretaker, real estate management). The booking system may be contemplated online: http://www.hetag.ch. (author)

Internet accessibility and disability policy: lessons for digital inclusion and equality from Australia

Directory of Open Access Journals (Sweden)

Gerard Goggin

2017-03-01

Full Text Available In the fifth decade of the internet, accessibility for all, especially those with disabilities, is central to digital inclusion. Yet internationally, the score card on internet and accessibility remains mixed, at best; and woefully inadequate, at worst. Via an Australian case study, we argue that it is imperative to better understand how internet technology interacts with the life worlds and dynamics of disability, and we suggest how policy can be articulated and improved to put people with disabilities on an equal basis to others in digital societies.

Tak, Sunghee H; Beck, Cornelia; McMahon, Ed

2007-05-01

In this study, the authors examined residents' computer and Internet access, as well as benefits and barriers to access in nursing homes. Administrators of 64 nursing homes in a national chain completed surveys. Fourteen percent of the nursing homes provided computers for residents to use, and 11% had Internet access. Some residents owned personal computers in their rooms. Administrators perceived the benefits of computer and Internet use for residents as facilitating direct communication with family and providing mental exercise, education, and enjoyment. Perceived barriers included cost and space for computer equipment and residents' cognitive and physical impairments. Implications of residents' computer activities were discussed for nursing care. Further research is warranted to examine therapeutic effects of computerized activities and their cost effectiveness.

Age and race-related disparities in technology use have been well documented, but less is known about how health literacy influences technology access and use. To assess the association between patients' literacy skills and mobile phone ownership, use of text messaging, Internet access, and use of the Internet for health-related purposes. A secondary analysis utilizing data from 1077 primary care patients enrolled in two, multisite studies from 2011-2013. Patients were administered an in-person, structured interview. Patients with adequate health literacy were more likely to own a mobile phone or smartphone in comparison with patients having marginal or low literacy (mobile phone ownership: 96.8 vs. 95.2 vs. 90.1%, respectively, P Internet from their home (92.1 vs. 74.7 vs. 44.9%, P Internet for email (93.0 vs. 75.7 vs. 38.5%, P technology access and use are widespread, with lower literate patients being less likely to own smartphones or to access and use the Internet, particularly for health reasons.

2012-03-01

The relationship between health information seeking, patient engagement and health literacy is not well understood. This is especially true in medically underserved populations, which are often viewed as having limited access to health information. To improve communication between an urban health centre and the community it serves, a team of library and information science researchers undertook an assessment of patients' level and methods of access to and use of the Internet. Data were collected in 53 face-to-face anonymous interviews with patients at the centre. Interviews were tape-recorded for referential accuracy, and data were analysed to identify patterns of access and use. Seventy-two percentage of study participants reported having access to the Internet through either computers or cell phones. Barriers to Internet access were predominantly lack of equipment or training rather than lack of interest. Only 21% of those with Internet access reported using the Internet to look for health information. The findings suggest that lack of access to the Internet in itself is not the primary barrier to seeking health information in this population and that the digital divide exists not at the level of information access but rather at the level of information use. © 2011 The authors.

2001-02-01

The Internet and the World Wide Web have revolutionised communication and provide a unique forum for the exchange of information. It has been proposed that the Internet has given the public more access to medical information resources and improved patient education. This study assessed the impact of the Internet on the availability of information on wound care management. The search phrases 'wound care', 'wound healing' and 'wounds' were analysed using a powerful Metacrawler search engine (www.go2net.com). Web site access was classified according to the target audience (wound-care specialists, other health professionals, patients) and the author (societies, institutions or commercial companies). The largest proportion of web sites were commercially based (32%). Of the total number, 23% specifically targeted patients, mostly by advertising. Only 20% were aimed at wound specialists. Extensive surfing was required to obtain wound-care information, and objective information sites were under-represented. Regulated, easily accessible, objective information sites on wound-healing topics are needed for improved patient education and to balance the existing commercial bias.

Full Text Available Using the Internet has become an essential part of many people's daily life activities. In this information age, the Internet is an indispensible tool for communicating and sharing of information. This transformation of technological incorporation into every aspect of social life has been relatively swift, although not all-inclusive. Lack of access to the Internet produces and perpetuates social inequality. In this paper we present results of a unique data set compiled from six studies conducted across twelve years in the state of North Carolina. Our results show differences in home access to the Internet are associated with various aspects of social stratification. The findings reveal that digital divide persists over time. At least one quarter of respondents with one or more of the following sociodemographic characteristics reported not having home Internet access: African Americans, those with only a high school degree or less, those without school-age children in the home, those with a household income less than $30,000, people age 69 years and older, and rural residents. Future research and policy recommendations are provided.

Full Text Available On the basis of Internet of Things (IoT technologies, Community Medical Internet of Things (CMIoT is a new medical information system and generates massive multiple types of medical data which contain all kinds of user identity data, various types of medical data, and other sensitive information. To effectively protect users’ privacy, we propose a secure privacy data protection scheme including transmission protection and access control. For the uplink transmission data protection, bidirectional identity authentication and fragmented multipath data transmission are used, and for the downlink data protection, fine grained access control and dynamic authorization are used. Through theoretical analysis and experiment evaluation, it is proved that the community medical data can be effectively protected in the transmission and access process without high performance loss.

2011-10-01

Full Text Available

ABSTRACT: Lexicographers working on finance dictionaries have not properly exploited the fast development of the Internet. This is revealed by the poor utilization of the access routes found in current Internet finance dictionaries. Consequently, users cannot effectively and efficiently find answers to their lexicographical problems. Firstly, there are Internet finance dictionaries which lack technological features and can simply be called meagre Internet dictionaries. Secondly, there are Internet finance dictionaries which utilize so many technological features that users incur high lexicographical information costs. In order to create better access routes, a sound theoretical foundation has to be established. This article shows that the implementation of the modern theory of lexicographical functions, which focuses on the users, results in a better design for future Internet finance dictionaries. With the proper theoretical basis, lexicographers will be able to create state-ofthe- art dictionaries that can provide effective and efficient solutions to lexicographical problems.

Healthy People 2020 (HP2020) aims to improve population health outcomes through several objectives, including health communication and health information technology. We used 7 administrations of the Health Information National Trends Survey to examine HP2020 goals toward access to the Internet through broadband and mobile devices (N = 34 080). We conducted descriptive analyses and obtained predicted marginals, also known as model-adjusted risks, to estimate the association between demographic characteristics and use of mobile devices. The HP2020 target (7.7% of the US population) for accessing the Internet through a cellular network was surpassed in 2014 (59.7%), but the HP2020 target (83.2%) for broadband access fell short (63.8%). Sex and age were associated with accessing the Internet through a cellular network throughout the years (Wald F test, P Internet through mobile devices presents an opportunity for technology-based health interventions that should be explored.

Computers are ubiquitous throughout the developed world. Diverse discourses address the pros and cons of using this technology in higher education. Nursing has extensively used informatics but has not, as yet, been involved to any extent in teaching on the Internet. I argue that nurse educators should use computer technology to present substantive and rigorous courses that deal with complex issues, using menopause as an example. A for-credit menopause course I taught via e-mail is used to illustrate the possibility of building knowledge and a sense of community on the Internet.

Rice, Eric; Winetrobe, Hailey; Holloway, Ian W; Montoya, Jorge; Plant, Aaron; Kordic, Timothy

2015-04-01

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

Due to the long life cycle of a building the expenses for usage and maintenance are very high compared to those for the construction, only. About 1/3 of the total energy demand in Germany is used for heating, air-conditioning and hot water supply in buildings. In addition the building wastes resulting for disposal represent a quantitatively enormous material flow. As the most significant decisions are made in early planning steps it is very important to enable planners to estimate the energy demand, resource requirement and ecological impact of different scenarios at this stage. Nowadays more and more architects and engineers use CAD software, like the Architectural Desktop from Autodesk, supporting the generation of three dimensional product models. One prominent model being now well established in the building industry is defined by the Industry Foundation Classes (IFC). This model is also the starting point of our resource oriented design system. To get a basis for a comparative assessment of different design variants it is first necessary to augment the product model with information on resource consumption of the used materials. Therefore a database server accessible via the Internet is developed within our research project providing a service for planners to extend their product model with information necessary for life cycle assessment (LCA) and building energy simulation (EnEV). The data exchange format for the property sets is ifcXML. In our presentation the general software concept together with first simulation tools will be discussed. (orig.)

Online access to health records and the ability to exchange secure messages with physicians can improve patient engagement and outcomes; however, the digital divide could limit access to web-based portals among disadvantaged groups. To understand whether sociodemographic differences in patient portal use for secure messaging can be explained by differences in internet access and care preferences. Cross-sectional survey to examine the association between patient sociodemographic characteristics and internet access and care preferences; then, the association between sociodemographic characteristics and secure message use with and without adjusting for internet access and care preference. One thousand forty-one patients with chronic conditions in a large integrated health care delivery system (76% response rate). Internet access, portal use for secure messaging, preference for in-person or online care, and sociodemographic and health characteristics. Internet access and preference mediated some of the differences in secure message use by age, race, and income. For example, using own computer to access the internet explained 52% of the association between race and secure message use and 60% of the association between income and use (Sobel-Goodman mediation test, Pdifferences in portal use remained statistically significant when controlling for internet access and preference. As the availability and use of patient portals increase, it is important to understand which patients have limited access and the barriers they may face. Improving internet access and making portals available across multiple platforms, including mobile, may reduce some disparities in secure message use.

Democracy and the Internet: Access, Engagement and Deliberation

Directory of Open Access Journals (Sweden)

Roman Gerodimos

2005-12-01

Full Text Available The internet has the capacity to facilitate the creation of new forms of civic engagement, but the realisation of these opportunities requires institutional and cultural reinforcement. The democratic character of e-citizenship and the equal distribution of online resources to the public require the fulfilment of four conditions: access, engagement (incorporating education, motivation and trust, meaningful deliberation and a link between civic input and public policy output. Furthermore, the gap between the main features of cyberspace and the inherent prerequisites of democracy, such as a finite space and a set of rules, create tensions that need to be negotiated politically. Although the empirical evidence available includes some encouraging signs regarding the future use of the internet for civic engagement, the existing limitations and obstacles mean that the new media will complement, rather than replace, the old media as a democratic public sphere.

Wang, Jong-Yi; Bennett, Kevin; Probst, Janice

2011-03-03

Access to health care is often contingent upon an individual's ability to travel for services. Certain groups, such as those with physical limitations and rural residents, have more travel barriers than other groups, reducing their access to services. The use of the Internet may be a way for these groups to seek care or information to support their health care needs. The purpose of this study was to examine Internet use among those whose are, for medical reasons, limited in their ability to travel. We also examined disparities in Internet use by race/ethnicity and rural residence, particularly among persons with medical conditions. We used data from the 2001 National Household Travel Survey (NHTS), a nationally representative sample of US households, to examine Internet use among individuals with medical conditions, rural residents, and minority populations. Internet use was defined as any use within the past 6 months; among users, frequency of use and location of use were explored. Control variables included sociodemographics, family life cycle, employment status, region, and job density in the community. All analyses were weighted to reflect the complex NHTS sampling frame. Individuals with medical conditions were far less likely to report Internet use than those without medical conditions (32.6% vs 70.3%, P digital divide between urban and rural residents. Internet use and frequency was also lower among those reporting a medical condition than among those without a condition. After we controlled for many factors, however, African Americans and Hispanics were still less likely to use the Internet, and to use it less often, than whites. Policy makers should look for ways to improve the access to, and use of, the Internet among these populations.

The use of Internet-based behavioral programs may be an efficient, flexible method to enhance prenatal care and improve pregnancy outcomes. There are few data about access to, and use of, the Internet via computers and mobile phones among pregnant women. We describe pregnant women's access to, and use of, computers, mobile phones, and computer technologies (eg, Internet, blogs, chat rooms) in a southern United States population. We describe the willingness of pregnant women to participate in Internet-supported weight-loss interventions delivered via computers or mobile phones. We conducted a cross-sectional survey among 100 pregnant women at a tertiary referral center ultrasound clinic in the southeast United States. Data were analyzed using Stata version 10 (StataCorp) and R (R Core Team 2013). Means and frequency procedures were used to describe demographic characteristics, access to computers and mobile phones, and use of specific Internet modalities. Chi-square testing was used to determine whether there were differences in technology access and Internet modality use according to age, race/ethnicity, income, or children in the home. The Fisher's exact test was used to describe preferences to participate in Internet-based postpartum weight-loss interventions via computer versus mobile phone. Logistic regression was used to determine demographic characteristics associated with these preferences. The study sample was 61.0% white, 26.0% black, 6.0% Hispanic, and 7.0% Asian with a mean age of 31.0 (SD 5.1). Most participants had access to a computer (89/100, 89.0%) or mobile phone (88/100, 88.0%) for at least 8 hours per week. Access remained high (>74%) across age groups, racial/ethnic groups, income levels, and number of children in the home. Internet/Web (94/100, 94.0%), email (90/100, 90.0%), and Facebook (50/100, 50.0%) were the most commonly used Internet technologies. Women aged less than 30 years were more likely to report use of Twitter and chat rooms

The digital divide: Examining socio-demographic factors associated with health literacy, access and use of internet to seek health information.

Science.gov (United States)

Estacio, Emee Vida; Whittle, Rebecca; Protheroe, Joanne

2017-02-01

This article aims to examine the socio-demographic characteristics associated with access and use of Internet for health-related purposes and its relationship with health literacy. Data were drawn from a health literacy survey ( N = 1046) and analysed using logistic regression. Results show a strong association between health literacy, internet access and use. Socio-demographic characteristics particularly age, education, income, perceived health and social isolation also predict internet access. Thus, in addition to widening access, the movement towards digitisation of health information and services should also consider digital skills development to enable people to utilise digital technology more effectively, especially among traditionally hard-to-reach communities.

Full Text Available Este artículo analiza el establecimiento de normas por parte de los progenitores a sus hijos sobre la utilización de Internet en los hogares. Los datos se han obtenido mediante encuestación sobre una muestra representativa de los menores de las Islas Baleares de entre 6 y 16 años, habiéndose analizado las siguientes dimensiones: acceso de los menores a Internet desde el hogar; grado de autonomía o acompañamiento en la navegación; normativización impuesta en el hogar por parte de sus padres y madres; tipos de normas impuestas; relación entre normas y género; valoración de los menores de los conocimientos y habilidades de sus progenitores para navegar por Internet y, finalmente, el acompañamiento de los padres y madres a la hora de navegar por Internet. Se constata que poco más del 53% de los menores de entre 6 y 14 años, y del 62% de los de 15 y 16 años navegan a través de Internet sin que sus progenitores les establezcan limitaciones. Cuando establecen algún tipo de normas, éstas se refieren, principalmente, a restricciones de carácter temporal. Por tanto, se infiere que los padres y madres no son conscientes de los peligros de la Red o que, al menos, actúan de forma poco razonable. Ello muestra la necesidad de sensibilizar y formar a las familias para que asuman su responsabilidad educativa.This paper examines and discusses the rules and standards set by parents for their children on Internet usage at home. Data that supports the paper have been obtained by surveying a representative sample of children in the Balearic Islands aged between 6 and 16 years; the analysis dimensions are: access by minors to the Internet from home; location of the computer from which have online access; level of autonomy or accompaniment while surfing the Net; norms imposed by their parents; types of rules imposed; relationship between norms and gender; the minors’ opinion and assessment of the knowledge and abilities of their parents on use of

Full Text Available This paper depicts a study conducted on the behavior of physical education students towards Internet usage at Kurukshetra University, Kurukshetra. Specially, the study aims to know the purposes for use of Internet resources and services, frequency of use, places and means of use, student's satisfaction level toward the Internet, and problems faced while using the Internet. A survey was carried out with a sample of 100 physical education students of Kurukshetra University and the response rate was 88%. A well-designed questionnaire was distributed to the students' sample. Amazingly, the results of the study reveal that usage of the Internet in research and education was not favored, whereas email, chatting, and sports websites were commonly used among students. The study also found that too much information on the Internet, slow access speeds, and finding relevant information were the main problems in using the Internet.

, cheap and customizable use of the mobile internet. We find that the internet is mainly used on the mobile phone because it is possible, easy and convenient. The main arguments for not using the internet on the mobile – never minding accessibility or not – are that it is not possible due to handset...... or subscription limitations, that it is too cumbersome to be practical or too expensive to be worth it. Notably the majority of young Danes do have a laptop and extensive wifi access so the purchase and use of smart phones and internet on the mobile is not likely to be THE potential internet access. Altogether we......The focus of this paper is on the adaptation and use of the internet on the mobile among young Danes.

Accessibility in Public Buildings: Efficiency of Checklist Protocols.

Science.gov (United States)

Andersson, Jonas E; Skehan, Terry

2016-01-01

In Sweden, governmental agencies and bodies are required to implement a higher level of accessibility in their buildings than that stipulated by the National Building and Planning Act (PBL). The Swedish Agency for Participation (MFD, Myndigheten för delaktighet) develops holistic guidelines in order to conceptualize this higher level of accessibility. In conjunction to these guidelines, various checklist protocols have been produced. The present study focuses on the efficiency of such checklist protocols. The study revolved around the use of a checklist protocol in assessments of two buildings in Stockholm: the new head office for the National Authority for Social Insurances (ASI) and the School of Architecture at the Royal Institute of Technology (KTH). The study included three groups: Group 1 and Group 2 consisted of 50 real estate managers employed by the ASI, while Group 3 consisted of three participants in a course at the KTH. The results were similar in all of the groups. The use of the checklist protocol generated queries, which related mainly to two factors: (1) the accompanying factsheet consisted of textual explanations with no drawings, photographs or illustrations and (2) the order of the questions in the checklist protocol was difficult to correlate with the two buildings' spatial logic of accessing, egressing and making use of the built space.

Ndibanje, Bruce; Lee, Hoon-Jae; Lee, Sang-Gon

2014-08-13

Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al. (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18-21 June 2012, pp. 588-592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

The present state of information communication technology makes it possible to devise and run computer-based e-laboratories accessible to any user with a connection to the Internet, equipped with very simple technical means and making full use of web services. Thus, the way is open for a new strategy of physics education with strongly global features, based on experiment and experimentation. We name this strategy integrated e-learning, and remote experiments across the Internet are the foundation for this strategy. We present both pedagogical and technical reasoning for the remote experiments and outline a simple system based on a server-client approach, and on web services and Java applets. We give here an outline of the prospective remote laboratory system with data transfer using the Internet School Experimental System (ISES) as hardware and ISES WEB Control kit as software. This approach enables the simple construction of remote experiments without building any hardware and virtually no programming, using a paste and copy approach with typical prebuilt blocks such as a camera view, controls, graphs, displays, etc. We have set up and operate at present seven experiments, running round the clock, with more than 12 000 connections since 2005. The experiments are widely used in practical teaching of both university and secondary level physics. The recording of the detailed steps the experimentor takes during the measurement enables detailed study of the psychological aspects of running the experiments. The system is ready for a network of universities to start covering the basic set of physics experiments. In conclusion we summarize the results achieved and experiences of using remote experiments built on the ISES hardware system.

Full Text Available Abstract Background Access to medical records on the Internet has been reported to be acceptable and popular with patients, although most published evaluations have been of primary care or office-based practice. We tested the feasibility and acceptability of making unscreened results and data from a complex chronic disease pathway (renal medicine available to patients over the Internet in a project involving more than half of renal units in the UK. Methods Content and presentation of the Renal PatientView (RPV system was developed with patient groups. It was designed to receive information from multiple local information systems and to require minimal extra work in units. After piloting in 4 centres in 2005 it was made available more widely. Opinions were sought from both patients who enrolled and from those who did not in a paper survey, and from staff in an electronic survey. Anonymous data on enrolments and usage were extracted from the webserver. Results By mid 2011 over 17,000 patients from 47 of the 75 renal units in the UK had registered. Users had a wide age range (90 yrs but were younger and had more years of education than non-users. They were enthusiastic about the concept, found it easy to use, and 80% felt it gave them a better understanding of their disease. The most common reason for not enrolling was being unaware of the system. A minority of patients had security concerns, and these were reduced after enrolling. Staff responses were also strongly positive. They reported that it aided patient concordance and disease management, and increased the quality of consultations with a neutral effect on consultation length. Neither patient nor staff responses suggested that RPV led to an overall increase in patient anxiety or to an increased burden on renal units beyond the time required to enrol each patient.

2018-04-01

Full Text Available The research features analysis of user-experience-based accessibility assessment and progress monitoring of buildings and public spaces; this analysis is used as a tool for facilitating the development of humane, socially sustainable and an inclusive urban environment. A group of users representing people with different kinds of disabilities, the elderly and families with children was created to assess the quality of access to various buildings with different functions and locations across Vilnius and in Singapore. A school, two hospitals, a rehab centre and two offices were selected for access monitoring in Vilnius City, while a hotel, a café and two metro stations with public squares were chosen for access assessment in Singapore. As the same method was principally applied to assess accessibility of selected buildings in Vilnius City in 2000 and 2017 and in Singapore in 2012, the article draws a comparative analysis of access levels in these two cities located in different global regions. The results show a definite improvement of access quality over time and also identify the critical aspects in this process. The segment of plot planning represents the lowest quality of access for all assessed building types as compared to the building segment and the external–internal element segments. The paper also draws conclusions that access improvement is a continuous process of implementing advanced urban policy instruments, and city planners can contribute to it by constantly analysing and presenting to public the monitoring data about the progress in access improvement. Comparing the assessment results between Vilnius City and Singapore – cities that are located in different global regions and in different socio-economic environments – provides a practical tool for benchmarking and setting the priorities for this process.

In the context of the arrival of massive service access requests at a virtual data center, this paper designs a massive sensing data access and control mechanism to improve the access efficiency of service requests and makes full use of the available resources at the data access center for the Internet of things. Firstly, this paper proposes a synergistically distributed buffer access model, which separates the information of resource and location. Secondly, the paper divides the service access requests into multiple virtual groups based on their characteristics and locations using an optimized self-organizing feature map neural network. Furthermore, this paper designs an optimal scheduling algorithm of group migration based on the combination scheme between the artificial bee colony algorithm and chaos searching theory. Finally, the experimental results demonstrate that this mechanism outperforms the existing schemes in terms of enhancing the accessibility of service requests effectively, reducing network delay, and has higher load balancing capacity and higher resource utility rate.

Highlights: > A dual-chambered internet-accessible heavily shielded facility has been built. > The facility allows distance users to analyze neutron irradiated samples remotely. > The Missouri S and T system uses computer automation with user feedback. > The system can analyze multiple samples and assist several researchers concurrently. - Abstract: A dual-chambered internet-accessible heavily shielded facility with pneumatic access to the University of Missouri Science and Technology (Missouri S and T) 200 kW Research Nuclear Reactor (MSTR) core has been built and is currently available for irradiation and analysis of samples. The facility allows authorized distance users engaged in collaborative activities with Missouri S and T to remotely manipulate and analyze neutron irradiated samples. The system consists of two shielded compartments, one for multiple sample storage, and the other dedicated exclusively for radiation measurements and spectroscopy. The second chamber has multiple detector ports, with graded shielding, and has the capability to support gamma spectroscopy using radiation detectors such as an HPGe detector. Both these chambers are connected though a rapid pneumatic system with access to the MSTR nuclear reactor core. This new internet-based system complements the MSTR's current bare pneumatic tube (BPT) and cadmium lined pneumatic tube (CPT) facilities. The total transportation time between the core and the hot cell, for samples weighing 10 g, irradiated in the MSTR core, is roughly 3.0 s. This work was funded by the DOE grant number DE-FG07-07ID14852 and expands the capabilities of teaching and research at the MSTR. It allows individuals who do not have on-site access to a nuclear reactor facility to remotely participate in research and educational activities.

Full Text Available The emergence of IEEE802.16 wireless standard technology (WiMAX has significantly increased the choice to operators for the provisioning of wireless broadband access network. WiMAX is being deployed to compliment with xDSL in underserved or lack of the broadband network area, in both developed and developing countries. Many incumbent operators in developing countries are considering the deployment of WiMAX as part of their broadband access strategy. This paper presents an efficient and simple method for planning of broadband fixed wireless access (BFWA with IEEE802.16 standard to support home connection to Internet. The study formulates the framework for planning both coverage and capacity designs. The relationship between coverage area and access rate from subscriber in each environment area is presented. The study also presents the throughput and channel capacity of IEEE802.16 in different access rates. An extensive analysis is performed and the results are applied to the real case study to demonstrate the practicality of using IEEE 802.16 for connecting home to Internet. Using empirical data and original subscriber traffic from measurement, it is shown that the BFWA with IEEE802.16 standard is a capacity limited system. The capacity of IEEE802.16 is related to different factors including frequency bandwidth, spectrum allocation, estimation of traffic per subscriber, and choice of adaptive modulation from subscriber terminal. The wireless access methods and procedures evolved in this research work and set out in this paper are shown to be well suited for planning BFWA system based on IEEE802.16 which supports broadband home to Internet connections.

2010-07-01

Access to high-speed Internet service is booming all over the world but the cost of optic cable installation and other related broadband delivery technology is still too high for many developing countries to afford. A Canada-India R & D group is working on a broadband technology delivered over the power line in order to provide internet access wherever there is electricity. Moreover, the application of such a technology in rural India could also improve the distribution and management of India's national electrical grid, as the risk of electricity theft can be monitored by power assumption tracking. Since the required infrastructure is already in place across the country, this project could be deployed rapidly and in a cost-efficient manner, providing thousands of potential opportunities for rural dwellers as well as for Indian and international companies.

The influence of the digital divide on face preferences in El Salvador: people without internet access prefer more feminine men, more masculine women, and women with higher adiposity.

Directory of Open Access Journals (Sweden)

Carlota Batres

Full Text Available Previous studies on face preferences have found that online and laboratory experiments yield similar results with samples from developed countries, where the majority of the population has internet access. No study has yet explored whether the same holds true in developing countries, where the majority of the population does not have internet access. This gap in the literature has become increasingly important given that several online studies are now using cross-country comparisons. We therefore sought to determine if an online sample is representative of the population in the developing country of El Salvador. In studies of Hispanic men and women aged 18-25, we tested facial masculinity and adiposity preferences by collecting data in person as well as online. Our results showed that there were no differences in preferences between people who reported having internet access, whether they were tested online or in person. This provides evidence that testing style does not bias preferences among the same population. On the other hand, our results showed multiple differences in preferences between people who reported having internet access and people who reported not having internet access. More specifically, we found that people without internet access preferred more feminine men, more masculine women, and women with higher adiposity than people with internet access. We also found that people without internet access had fewer resources (e.g. running water than people with internet access, suggesting that harshness in the environment may be influencing face preferences. These findings suggest that online studies may provide a distorted perspective of the populations in developing countries.

Behavioral parent training (BPT) has been shown to be efficacious to improve parenting skills for problematic interactions with adolescents displaying oppositional and antisocial behaviors. Some research suggests that support group curricula might be transferred to the Internet, and some studies suggest that other curriculum designs might also be effective. In this research, a BPT program for parents of at-risk adolescents was tested on the Internet in a randomized trial (N = 307) from computer labs at six community technology centers in or near large metropolitan areas. The instructional design was based on asynchronous scenario-based e-learning, rather than a traditional parent training model where presentation of course material builds content sequentially over multiple class sessions. Pretest to 30-day follow-up analyses indicated significant treatment effects on parent-reported discipline style (Parenting Scale, Adolescent version), child behavior (Eyberg Child Behavior Inventory), and on social cognitive theory constructs of intentions and self-efficacy. The effect sizes were small to medium. These findings suggest the potential to provide effective parent training programs on the Internet.

A building’s environment has profound influence on occupant comfort and health. Continuous monitoring of building occupancy and environment is essential to fault detection, intelligent control, and building commissioning. Though many solutions for environmental measuring based on wireless sensor networks exist, they are not easily accessible to households and building owners who may lack time or technical expertise needed to set up a system and get quick and detailed overview of environmental conditions. Building-in-Briefcase (BiB) is a portable sensor network platform that is trivially easy to deploy in any building environment. Once the sensors are distributed, the environmental data is collected and communicated to the BiB router via the Transmission Control Protocol/Internet Protocol (TCP/IP) and WiFi technology, which then forwards the data to the central database securely over the internet through a 3G radio. The user, with minimal effort, can access the aggregated data and visualize the trends in real time on the BiB web portal. Paramount to the adoption and continued operation of an indoor sensing platform is battery lifetime. This design has achieved a multi-year lifespan by careful selection of components, an efficient binary communications protocol and data compression. Our BiB sensor is capable of collecting a rich set of environmental parameters, and is expandable to measure others, such as CO 2 . This paper describes the power characteristics of BiB sensors and their occupancy estimation and activity recognition functionality. We have demonstrated large-scale deployment of BiB throughout Singapore. Our vision is that, by monitoring thousands of buildings through BiB, it would provide ample research opportunities and opportunities to identify ways to improve the building environment and energy efficiency.

2005-06-28

Providers of health care usually have much better information about health and health care interventions than do consumers. The internet is an important and rapidly evolving source of global health-related information and could provide a means of correcting for asymmetric information. However, little is known about who accesses this information and how it is used in New Zealand. The aims of this research were to: determine the nature of the health information sought, how respondents use the information, how helpful they perceive the information to be, and the self-assessed value of such information. The researchers conducted an anonymous five minute telephone and mall intercept survey of randomly selected Wellington residents who had searched for health-related information on the internet. Investigators entered the data into an Excel spreadsheet and transferred it to SPSS for data cleaning, data exploration and statistical analysis. Search time costs were based on the opportunity cost of income foregone and respondents were asked to provide a money value for the information found. Eighty-three percent of respondents accessed the internet from home, and 87% conducted the search for themselves. Forty-five percent of people were looking for general health and nutrition information, 42% for data about a specific illness and 40% for a medicine. After finding the information, 58% discussed it with a family member/friend/workmate, 36% consulted a general practitioner, 33% changed their eating or drinking habits, and 13% did nothing. Respondents found the information very quick to find and useful. It took them on average 0.47 hours and cost $12 (opportunity cost of time) to find the information. The average value of the data found was $60 and the net benefit to the consumer was $48 ($60 - $12). The results of this research could assist providers of health information via the internet to tailor their websites to better suit users' needs. Given the high perceived value of

David Ward

2000-01-01

Full Text Available Internet knowledge is increasing steadily among instructors in the academic world. As courses incorporate more instructional technology, traditional undergraduate research assignments are adapting to reflect the changing world of information and information access. New library assignments reflect this shift as well, with term papers and research projects asking students to use Web sites as an information resource, in addition to the standard literature of periodicals and monographs. But the many pitfalls the library profession has learned in its own metamorphosis during the past decade are often repeated in these newer course assignments. The authors in this paper present a framework for librarians to interact with instructors to incorporate Internet resources into traditional term paper and research assignments. They suggest a framework for creating sample assignments librarians can take to campus instructional units, to show the teaching community at large what the library profession has learned from first-hand experience.

The insurance mandate of the Affordable Care Act has increased the number of people with health coverage in the United States. There is speculation that this increase in the number of insured could make accessing health care services more difficult. Those who are unable to access care in a timely manner may use the Internet to search for information needed to answer their health questions. The aim was to determine whether difficulty accessing health care services for reasons unrelated to insurance coverage is associated with increased use of the Internet to obtain health information. Survey data from 32,139 adults in the 2011 National Health Interview Study (NHIS) were used in this study. The exposure for this analysis was reporting difficulty accessing health care services or delaying getting care for a reason unrelated to insurance status. To define this exposure, we examined 8 questions that asked whether different access problems occurred during the previous 12 months. The outcome for this analysis, health information technology (HIT) use, was captured by examining 2 questions that asked survey respondents if they used an online health chat room or searched the Internet to obtain health information in the previous 12 months. Several multinomial logistic regressions estimating the odds of using HIT for each reported access difficulty were conducted to accomplish the study objective. Of a survey population of 32,139 adults, more than 15.90% (n=5109) reported experiencing at least one access to care barrier, whereas 3.63% (1168/32,139) reported using online health chat rooms and 43.55% (13,997/32,139) reported searching the Internet for health information. Adults who reported difficulty accessing health care services for reasons unrelated to their health insurance coverage had greater odds of using the Internet to obtain health information. Those who reported delaying getting care because they could not get an appointment soon enough (OR 2.2, 95% CI 1.9-2.5), were

The aim of this study was to test for associations between different aspects of contract and on-board internet access and seafarers' satisfaction and health. Altogether 298 Croatian seafarers, all officers, employed on cargo ships, with a minimum work experience of two years with their current shipping company, participated in an online survey. The questionnaire included sociodemographic items, questions relating to their employment contract and internet access, and measures of job satisfaction, life satisfaction, mental health, and gastrointestinal and cardiovascular symptoms. Their job- and lifesatisfaction levels were higher for shorter duration on board, favourable ratio of work to non-work days, and compliance with the employment contract regarding the changes to work and non-work days. Mental health differed likewise but only in relation to two aspects of the contract: on-board duration and compliance with the contract. The level of gastrointestinal symptoms was lower in cases of shorter on-board duration and compliance with the contract, and in seafarers who have free, unlimited internet access on board. Lower level of cardiovascular symptoms was found in seafarers with free, unlimited internet access on board. Our findings suggest that in promoting satisfaction and health in seafaring, attention should be given to reducing on-board duration, compliance with the contract, and internet accessibility on board.

Full Text Available English language skills here mean the development of the main parts or elements of the language which include speaking, listening, reading, and writing. English language subject has different educational tools that are likely suited with it. Smartphone and internet usage have actively influence daily life, even for children and adolescents. In learning activity, smartphone is a tool to help students connected to be online. A qualitative approach was pursued in this study. Then, the data collection technique used in this study is a survey by using questionnaires. As result, the research shows that most students spend much time to access the social network, some students access internet for dictionary and games, and only a few students access internet for education purposes. In short, the students rather to use smartphone for other thing than education. Therefore, English language learning should be focused on leading language teaching by using English resources from smartphone and internet, as media, which closed to students. By using smartphone and internet, it is expected that either teacher or students become more active and creative to explore their knowledge through media. Pedagogically, there is an urgent need for teachers to implement smartphone-based language learning in order to engage students to be critics with material and its content. So, it enables students to build and enhance a technology awareness of smartphone and internet usage on English language learning in classroom.

Helium gas suicides have increased in England and Wales; easy-to-access descriptions of this method on the Internet may have contributed to this rise. To investigate the availability of information on using helium as a method of suicide and trends in searching about this method on the Internet. We analyzed trends in (a) Google searching (2004-2014) and (b) hits on a Wikipedia article describing helium as a method of suicide (2013-2014). We also investigated the extent to which helium was described as a method of suicide on web pages and discussion forums identified via Google. We found no evidence of rises in Internet searching about suicide using helium. News stories about helium suicides were associated with increased search activity. The Wikipedia article may have been temporarily altered to increase awareness of suicide using helium around the time of a celebrity suicide. Approximately one third of the links retrieved using Google searches for suicide methods mentioned helium. Information about helium as a suicide method is readily available on the Internet; the Wikipedia article describing its use was highly accessed following celebrity suicides. Availability of online information about this method may contribute to rises in helium suicides.

Access to the Internet has grown dramatically over the past two decades. Using data from a population-based survey, we aimed to determine the prevalence and predictors of (i) access to the Internet, and (ii) use of the Internet to search for health information. We analyzed data from the 2011-12 California Health Interview Survey (CHIS) and included all individuals 18 years of age and older. Our outcomes were (i) prior use of the Internet, and (ii) use of the Internet to find health or medical information within the past year. We performed survey-weighted logistic regression models on our outcomes to adjust for potentially confounding demographic and socioeconomic factors. Our study included an unweighted and survey-weighted sample of 42,935 and 27,796,484 individuals, respectively. We found that 81.5% of the weighted sample reported having previously used the Internet. Among Internet users, 64.5% stated that they used the Internet within the past year to find health or medical information. Racial/ethnic minorities, older individuals, and those who lived in lower income households and rural areas were less likely to have access to and use the Internet to search for health information. Conversely, English-proficiency and increasing levels of education were positively associated with online health information-seeking. We found that most Californians have access to and use the Internet to search for health information, but still noted a persistent digital divide. Interventions to narrow the divide are needed, otherwise this may lead to a continued widening of existing healthcare disparities. Copyright © 2017 Elsevier B.V. All rights reserved.

Internet access has lagged behind for patients with lower incomes and from certain ethnic groups. This study investigated the possible improvement of access to health-related information on the Internet for all patients in an urban outpatient setting, regardless of socioeconomic background. A 28-question survey was completed by 100 orthopedic outpatients evaluating associations between their age, ethnicity, income, or education level and their access to the Internet. The survey also examined how patients used the Internet to obtain information about their medical condition, their privacy concerns when conducting online research, and their use of mobile phones as a primary means of Internet access. The Internet was used by 57% of orthopedic outpatients in this urban setting. Internet access decreased with advancing age but increased with increasing income and education, findings consistent with similar studies. Despite the inability to identify an association between ethnicity and Internet access in this patient population, fewer Latinos (33%) than whites (67%) or African Americans (77%) sought information about their medical condition. Among patients who used a mobile phone as the primary method for online access, 74% were African American or Latino and 26% were white. This difference in mobile phone use for online access suggests that mobile phones have provided ethnic minorities with greater Internet access and thus may have narrowed the digital divide among the races.

2011-01-01

The Internet has increasingly become an intrinsic part of everyday life, offering countless possibilities for education, services, recreation, and more. In fact, an entire virtual life within the digitalized World Wide Web is possible and common among many Internet users. Today's psychiatrists must therefore incorporate this dimension of human life into clinical practice, to achieve an adequate assessment of the tools and risks available to the patient. We focus on the Internet as a portal for the trade of and access to substances of abuse. We review the legal regulations that may inform care and standards of practice and analyze the difficulties that arise in assessment and monitoring of the current situation. We consider the potential impact of Internet-based narcotics trade on addiction morbidities and the practice of clinical psychiatry, as well as on the potential legal implications that the forensic expert may face.

This study aimed to explore inequities in access to online health information and its relation to socioeconomic status, and to inform the development of the use of the Internet for health promotion. We analyzed cross-sectional baseline survey data for 664 first-time mothers from the Healthy Beginnings Trial conducted in Southwest Sydney, Australia during 2007-2010. First-time mothers' reports of their computer ownership, sources of health information including Internet access and self-rated health as well as demographic data were collected through face-to-face interviews. Multivariate analysis was performed using log-binomial regression. We found that 37% of first-time mothers reported not using the Internet for health information. Maternal education level, household income level and having a computer at home were significant factors associated with the use of the Internet for health information after adjusting for other factors. Mothers who only had school certificate or lower were 1.5 times more likely not to use the Internet for health information than those with university/tertiary education [adjusted risk ratio (ARR) 1.50, 95% CI 1.06-2.12, P=0.03]. Mothers with a household income of less than $40,000 per year were 1.7 times more likely not to use the Internet for health information than those with a household income over $80,000 per year (ARR 1.66, 95% CI 1.24-2.12, P=0.001). These findings have important implications for using the Internet for health promotion among young women. A substantial number of first-time mothers do not access the Internet for health information, in particular among those with lower levels of education, lower household income and without a computer at home.

2017-12-01

Full Text Available Used and developed initially for the IT industry, the Cloud computing and Internet of Things concepts are found at this moment in a lot of sectors of activity, building industry being one of them. These are defined like a global computing, monitoring and analyze network, which is composed of hardware and software resources, with the feature of allocating and dynamically relocating the shared resources, in accordance with user requirements. Data analysis and process optimization techniques based on these new concepts are used increasingly more in the buildings industry area, especially for an optimal operations of the buildings installations and also for increasing occupants comfort. The multitude of building data taken from HVAC sensor, from automation and control systems and from the other systems connected to the network are optimally managed by these new analysis techniques. Through analysis techniques can be identified and manage the issues the arise in operation of building installations like critical alarms, nonfunctional equipment, issues regarding the occupants comfort, for example the upper and lower temperature deviation to the set point and other issues related to equipment maintenance. In this study, a new approach regarding building control is presented and also a generalized methodology for applying data analysis to building services data is described. This methodology is then demonstrated using two case studies.

To examine Internet access and interest in receiving nutrition education via social media applications among low-income adults participating in the Supplemental Nutrition Assistance Program Education (SNAP-Ed). A cross-sectional survey was distributed during 25 SNAP-Ed classes throughout the 16 southernmost counties of Illinois. From 188 responses, the majority of participants had Internet access (76%). Among participants aged 18-32 years (n = 51), 92% owned a smartphone with Internet access and 57% indicated that they would use online nutrition education, with most interest in e-mail (41%), Facebook (40%), and text messaging (35%). There was little interest in using blogs, Vine, Twitter, Tumblr, and Pinterest. Overall, 49% of middle-aged adults aged 33-64 years and 87% of seniors aged ≥65 years reported they would not use online nutrition education. Results indicated similar Internet accessibility in southern Illinois among low-income populations compared with national rural rates. Interest in using online nutrition education varied among SNAP-Ed participants according to age. Young adults appeared to be the most captive audience regarding online nutrition education. Results may be useful to agencies implementing SNAP-Ed to supplement current curriculum with online nutrition education for audiences aged ≤32 years.

Accessing files in an Internet: The Jade file system

Science.gov (United States)

Peterson, Larry L.; Rao, Herman C.

1991-01-01

Jade is a new distribution file system that provides a uniform way to name and access files in an internet environment. It makes two important contributions. First, Jade is a logical system that integrates a heterogeneous collection of existing file systems, where heterogeneous means that the underlying file systems support different file access protocols. Jade is designed under the restriction that the underlying file system may not be modified. Second, rather than providing a global name space, Jade permits each user to define a private name space. These private name spaces support two novel features: they allow multiple file systems to be mounted under one directory, and they allow one logical name space to mount other logical name spaces. A prototype of the Jade File System was implemented on Sun Workstations running Unix. It consists of interfaces to the Unix file system, the Sun Network File System, the Andrew File System, and FTP. This paper motivates Jade's design, highlights several aspects of its implementation, and illustrates applications that can take advantage of its features.

Houlihan, Bethlyn Vergo; Drainoni, Mari-Lynn; Warner, Grace; Nesathurai, Shanker; Wierbicky, Jane; Williams, Steven

2003-04-22

A pilot study was undertaken regarding the effect of Internet access on health-related quality of life (HRQoL) and self-reported impact for people with spinal cord injuries (SCI). This study is unique in providing free Internet access and looking at benefits for people with disabilities. HRQoL was measured using indicators of global health and social isolation at baseline and after 6 to 19 months of use via telephone interviews on a convenience sample of 23 adults with SCI. Additionally, monthly telephone surveys measured usage patterns, recreation, and self-reported impact. Both quantitative and qualitative analyses were conducted. Bivariate tests for differences in proportions and paired T-tests were conducted. Qualitatively, conceptual categories of impact were created using the Constant Comparative Method. Qualitatively, the predominant benefit was quality of life, mentioned by 61% of participants 46% of months surveyed, with quantitative trends towards improved emotional health. Ease of access to information, social connection, and quality of information were also frequently reported, with modest support from quantitative data. The study's persuasive qualitative results suggest the Internet has particular benefit to people with disabilities and that rehabilitation goals should include leisure. Further scientific research is strongly warranted.

Robert, Anna; Suelves, Josep Maria; Armayones, Manuel; Ashley, Sivakamy

2015-04-01

Suicidal behavior is a common and severe health problem around the world. Internet use has been related to an increase in suicidal behaviors, but few studies have focused on the potential benefits of Internet use for preventing self-harm and suicide. We reviewed the existing literature on the relationship between suicide and Internet use. The accessibility of suicide-related information on the Internet seems to have an impact on the incidence of suicide behaviors. However, the Internet is useful for linking people who feel lonely or isolated, and it provides access to suicide prevention information and resources. The Internet can influence vulnerable people to attempt suicide, but it can also be used to prevent self-harm and suicide. We propose some efforts that can be made in this preventive line.

Flexible and Lightweight Access Control for Online Healthcare Social Networks in the Context of the Internet of Things

Directory of Open Access Journals (Sweden)

Zhen Qin

2017-01-01

Full Text Available Online healthcare social networks (OHSNs play an essential role in sharing information among medical experts and patients who are equipped with similar experiences. To access other patients’ data or experts’ diagnosis anywhere and anytime, it is necessary to integrate the OHSN into the Internet as part of the Internet of Things (IoT. Therefore, it is crucial to design an efficient and versatile access control scheme that can grant and revoke a user to access the OHSN. In this paper, we propose novel attribute-based encryption (ABE features with user revocation and verifiable decryption outsourcing to control the access privilege of the users. The security of the proposed ABE scheme is given in the well-studied random oracle model. With the proposed ABE scheme, the malicious users can be excluded from the system and the user can offload most of the overhead in the decryption to an untrusted cloud server in a verifiable manner. An access control scheme for the OHSN has been given in the context of the IoT based on the proposed ABE scheme. The simulation demonstrates that our access control mechanism is practical.

2012-01-01

The digital divide is described as the gap between those who do and do not have access to digital information and communications technologies (ICT). ICTs are viewed as an indicator of infrastructure and potential for development, and are a growing platform for health information and services delivery. This study compares the penetration of mobile and broadband Internet technologies by global region from 2000 to 2010. Results illustrate the rapid growth of mobile cellular telephone subscriptions in all global regions with trends suggesting a continued increase. Little to modest gains were made in fixed broadband Internet subscriptions globally. There is a growing popularity of mobile subscriptions with use of data communications, exceeding the numbers of fixed Internet subscriptions. This comparison reveals current strengths that can be built on and highlights the importance of awareness of global trends and using such knowledge to inform design and delivery of ICT-based health services.

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. 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. 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, pdesignation (B=-0.343) educational qualification (B=2.411) significantly influence utilization of web-based health information resources of the respondents.

Background According to the Digital Agenda for Europe, the way children use the Internet and mobile technologies has changed dramatically in the past years. Objective The aims of this study were to: (1) breakdown the modalities of access and use of the Internet by teenagers to assess risks and risky behaviors; and (2) provide scientific data to evaluate and counsel safe use of the Internet and new technologies by teenagers. Methods The study was conducted under the program “Strategies for a Better Internet for Children” started in May 2012 by the European Commission. It represents the main result of the project launched by Telecom Italia, “Anche io ho qualcosa da dire” (I too have something to say), thanks to which many contributions were collected and used to develop a survey. The questionnaire was structured in 45 questions, covering three macro areas of interest. It was approved by the Department Board at University of Magna Graecia’s School of Medicine. After authorization from the regional high school authority, it was administered to all 1534 students (aged 13-19 years) in the city of Catanzaro, Italy. Results The data was broken down into three main groups: (1) describing education and access to the Internet; (2) methods of use and social networking; and (3) perception and evaluation of risk and risky behaviors. Among noteworthy results in the first group, we can mention that the average age of first contact with information technologies was around 9 years. Moreover, 78.87% (1210/1534) of the interviewed students reported having access to a smartphone or a tablet. Among the results of the second group, we found that the most used social networks were Facebook (85.78%, 1316/1534), YouTube (61.14%, 938/1534), and Google+ (51.56%, 791/1534). About 71.31% (1094/1534) of the interviewed teenagers use their name and surname on social networks, and 40.09% (615/1534) of them knew all their Facebook contacts personally.

Purpose: The Internet is an important information source for health practitioners providing immediate access to the most current health and medical information. Factors limiting practitioner access to the Internet have been identified and the literature shows that access to the Internet varies across and within health professions. There is therefore a need for each health profession to investigate practitioner access to the Internet. There has been, however, no identified empirical research investigating medical radiation science (MRS) practitioner access to or use of the Internet. This research sought to establish the professional use of Internet-based tools by Australian MRS practitioners and issues affecting access to the Internet within MRS workplaces. Methods: Qualitative and quantitative approaches were used in this research. These included interviews with 28 MRS practitioners from the four areas of specialisation, namely nuclear medicine, radiation therapy, radiography and sonography and a survey of MRS practitioners. In 2007 a 4-page postal survey was sent to a random sample of 1142 MRS practitioners with a response rate of 32.8%. Results: The Internet is an important information source widely used by MRS practitioners. MRS practitioners search the Internet (87%), access specific web pages (86%), use email (82%) and listservs (39.4%) to update their professional knowledge. It was evident that access to the Internet within the workplace varied within the MRS profession. Whilst the majority (96.4%) of MRS practitioners had some level of access to the Internet in their workplace, factors shown to affect practitioner access were workplace setting (p = 0.000), work environment (p = 0.000), and geographic location (p = 0.025). The majority of clinical workplaces (81%) did not provide practitioners with remote access to electronic resources available in the workplace such as e-journals and databases. Conclusions: This research provides baseline data to the MRS

  Women need access to evidence-based information to make informed choices in pregnancy. A search for health information is one of the major reasons that people worldwide access the Internet. Recent years have witnessed an increase in Internet usage by women seeking pregnancy-related information. The aim of this study was to build on previous quantitative studies to explore women's experiences and perceptions of using the Internet for retrieving pregnancy-related information, and its influence on their decision-making processes.   This global study drew on the interpretive qualitative traditions together with a theoretical model on information seeking, adapted to understand Internet use in pregnancy and its role in relation to decision-making. Thirteen asynchronous online focus groups across five countries were conducted with 92 women who had accessed the Internet for pregnancy-related information over a 3-month period. Data were readily transferred and analyzed deductively.   The overall analysis indicates that the Internet is having a visible impact on women's decision making in regards to all aspects of their pregnancy. The key emergent theme was the great need for information. Four broad themes also emerged: "validate information,"empowerment,"share experiences," and "assisted decision-making." Women also reported how the Internet provided support, its negative and positive aspects, and as a source of accurate, timely information.   Health professionals have a responsibility to acknowledge that women access the Internet for support and pregnancy-related information to assist in their decision-making. Health professionals must learn to work in partnership with women to guide them toward evidence-based websites and be prepared to discuss the ensuing information. © 2011, Copyright the Authors.

Full Text Available Background: Health information is one of the most accessed topics online. Worldwide, about 4.5% of all Internet searches are for health-related informationand more than 70, 000 websites disseminate health information. However, critics question the quality and credibility of online health information as contents are mostly a result of limited research or are commercialised. There is a need to train people to locate relevant websites where they can efficiently retrieve evidence based information and evaluate the same. The study was conducted with the objectives of determining the prevalence of use of internet for accessing healthcare information amongst literate adult population in an urban area and to assess the association between the demography and the reasons of internet use. Methodology: We used an anonymous, cross sectional survey completed by a sample of out patients of 408 individuals who came to a tertiary care centre at Pune during the year 2015. The survey consisted of 17 questions related to behavioural, attitudinal and demographic items. Results: Out of the total of 408 individuals, 256 (63.2% individuals used internet for health information though 332 (82.4% of them were aware of authorised websites for health information and 69 (16.9% thought information available in the internet can be harmful. Also, 63 out of 256 (24.6% agreed to the fact that they ask questions to their doctors based on the information that they acquired from internet while surfing about that particular disease/ ailment. More individuals (p<0.05 who were working and who were educated, graduates and above, were using internet for health information. Conclusion: Our results suggest the great potential for using the internet to disseminate the information and awareness to the public about health and healthcare facilities. However, it is important to disseminate credible information from reliable and authorised websites assigned for health since online healthcare

The Internet's potential impact on suicide is of major public health interest as easy online access to pro-suicide information or specific suicide methods may increase suicide risk among vulnerable Internet users. Little is known, however, about users' actual searching and browsing behaviors of online suicide-related information. To investigate what webpages people actually clicked on after searching with suicide-related queries on a search engine and to examine what queries people used to get access to pro-suicide websites. A retrospective observational study was done. We used a web search dataset released by America Online (AOL). The dataset was randomly sampled from all AOL subscribers' web queries between March and May 2006 and generated by 657,000 service subscribers. We found 5526 search queries (0.026%, 5526/21,000,000) that included the keyword "suicide". The 5526 search queries included 1586 different search terms and were generated by 1625 unique subscribers (0.25%, 1625/657,000). Of these queries, 61.38% (3392/5526) were followed by users clicking on a search result. Of these 3392 queries, 1344 (39.62%) webpages were clicked on by 930 unique users but only 1314 of those webpages were accessible during the study period. Each clicked-through webpage was classified into 11 categories. The categories of the most visited webpages were: entertainment (30.13%; 396/1314), scientific information (18.31%; 240/1314), and community resources (14.53%; 191/1314). Among the 1314 accessed webpages, we could identify only two pro-suicide websites. We found that the search terms used to access these sites included "commiting suicide with a gas oven", "hairless goat", "pictures of murder by strangulation", and "photo of a severe burn". A limitation of our study is that the database may be dated and confined to mainly English webpages. Searching or browsing suicide-related or pro-suicide webpages was uncommon, although a small group of users did access websites that contain

The 802.11 network (wireless fidelity/WiFi) is the most common wireless infrastructure applied for internet access indoor. Widespread devices and installation simplicity make it better than similar technologies such as 802.16 and other 802.xx series. The access points are the most influential devices for indoor access. However, building indoor architectures contribute to the signal quality. Since WiFi installation in buildings becomes prevalent, the architecture should consider WiFi-friendliness into consideration. The more friendly the building to WiFi signal, the more efficient the 802.11 based wireless infrastructure. This paper present preliminary study how the building, specially the obstacle material, effects the WiFi signal propagation indoor. The study was performed by using ESP8266-based WiFi signal reader, to determine the impact indoor obstacles to WiFi signal propagation. The initial study shows that simple reflecting materials increase signal level about 1.14 dBm. WiFi-friendly building can be achieved by transforming building properties into signal interconnector. A simple photo frame with aluminium sheet insertion increase signal level on the second floor up to 6.56dBm.

The digital divide is described as the gap between those who do and do not have access to digital information and communications technologies (ICT). ICTs are viewed as an indicator of infrastructure and potential for development, and are a growing platform for health information and services delivery. This study compares the penetration of mobile and broadband Internet technologies by global region from 2000 to 2010. Results illustrate the rapid growth of mobile cellular telephone subscriptions in all global regions with trends suggesting a continued increase. Little to modest gains were made in fixed broadband Internet subscriptions globally. There is a growing popularity of mobile subscriptions with use of data communications, exceeding the numbers of fixed Internet subscriptions. This comparison reveals current strengths that can be built on and highlights the importance of awareness of global trends and using such knowledge to inform design and delivery of ICT-based health services.

Wong, K.; Veness, M.

2003-01-01

The past decade has seen an 'explosion' in electronically archived evidence available on the Internet. Access to, and awareness of, pre-appraised web based evidence such as is available at the Cochrane Library, and more recently the Cancer Library, is now easily accessible to both clinicians and patients. A postal survey was recently sent out to all Radiation Oncology registrars in Australia, New Zealand and Singapore. The aim of the survey was to ascertain previous training in literature searching and critical appraisal, the extent of Internet access and use of web based evidence and awareness of databases including the Cochrane Library. Sixty six (66) out of ninety (90) registrars responded (73% response rate). Fifty five percent of respondents had previously undertaken some form of training related to literature searching or critical appraisal. The majority (68%) felt confident in performing a literature search, although 80% of respondents indicated interest in obtaining further training. The majority (68%) reported accessing web-based evidence for literature searching in the previous week, and 92% in the previous month. Nearly all respondents (89%) accessed web-based evidence at work. Most (94%) were aware of the Cochrane Library with 48% of respondents having used this database. Sixty-eight percent were aware of the Cancer Library. In 2000 a similar survey revealed only 68% of registrars aware and 30% having used the Cochrane Library. These findings reveal almost universal access to the Internet and use of web-based evidence amongst Radiation Oncology registrars. There has been a marked increase in awareness and use of the Cochrane Library with the majority also aware of the recently introduced Cancer Library

An Internet of Things Based Multi-Level Privacy-Preserving Access Control for Smart Living

Directory of Open Access Journals (Sweden)

Usama Salama

2018-05-01

Full Text Available The presence of the Internet of Things (IoT in healthcare through the use of mobile medical applications and wearable devices allows patients to capture their healthcare data and enables healthcare professionals to be up-to-date with a patient’s status. Ambient Assisted Living (AAL, which is considered as one of the major applications of IoT, is a home environment augmented with embedded ambient sensors to help improve an individual’s quality of life. This domain faces major challenges in providing safety and security when accessing sensitive health data. This paper presents an access control framework for AAL which considers multi-level access and privacy preservation. We focus on two major points: (1 how to use the data collected from ambient sensors and biometric sensors to perform the high-level task of activity recognition; and (2 how to secure the collected private healthcare data via effective access control. We achieve multi-level access control by extending Public Key Infrastructure (PKI for secure authentication and utilizing Attribute-Based Access Control (ABAC for authorization. The proposed access control system regulates access to healthcare data by defining policy attributes over healthcare professional groups and data classes classifications. We provide guidelines to classify the data classes and healthcare professional groups and describe security policies to control access to the data classes.

One of the challenges in astronomy education today is to introduce college students to the real-world practice and science of observational astronomy. Along with a good theoretical background, college students can gain an earlier, deeper understanding of the astronomy profession through direct observational and data reduction experience. However, building and managing a modest observatory is still too costly for many colleges and universities. Fortunately, advances in commercial astronomical hardware and software now allow universities to build and operate small Internet controllable observatories for a modest investment. The advantages of an Internet observatory include: 1) remote operation from a comfortable location, 2) immediate data access, 3) telescope control via a web browser, and 4) allowing both on-campus and distance education students the ability to conduct a variety of observing projects. Internet capabilities vastly expand the number of students who will be able to use the observatory, thus exposing them to astronomy as a science and as a potential career. In September 2005, the University of North Dakota (UND) Department of Space Studies began operating a small, recently renovated Internet controllable observatory. Housed within a roll-off roof 10 miles west of UND, the observatory includes a Meade 16-inch, f/10 Schmidt-Cassegrain telescope, an SBIG STL-6303e CCD with broadband filters, ACP observatory control software, focuser, and associated equipment. The observatory cost \\25,000 to build in 1996; 2005 renovation costs total \\28,000. An observatory operator prepares the telescope for use each night. Through remote operation, the roof is opened and the telescope/CCD power is turned on. The telescope is then aligned and focused before allowing students to access the observatory. Students communicate with the observatory operator via an online chat room and via telephone, if necessary, to answer questions and resolve any problems. Additional

Weinstein, Aviv; Lejoyeux, Michel

2010-09-01

Problematic Internet addiction or excessive Internet use is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding computer use and Internet access that lead to impairment or distress. Currently, there is no recognition of internet addiction within the spectrum of addictive disorders and, therefore, no corresponding diagnosis. It has, however, been proposed for inclusion in the next version of the Diagnostic and Statistical Manual of Mental Disorder (DSM). To review the literature on Internet addiction over the topics of diagnosis, phenomenology, epidemiology, and treatment. Review of published literature between 2000-2009 in Medline and PubMed using the term "internet addiction. Surveys in the United States and Europe have indicated prevalence rate between 1.5% and 8.2%, although the diagnostic criteria and assessment questionnaires used for diagnosis vary between countries. Cross-sectional studies on samples of patients report high comorbidity of Internet addiction with psychiatric disorders, especially affective disorders (including depression), anxiety disorders (generalized anxiety disorder, social anxiety disorder), and attention deficit hyperactivity disorder (ADHD). Several factors are predictive of problematic Internet use, including personality traits, parenting and familial factors, alcohol use, and social anxiety. Although Internet-addicted individuals have difficulty suppressing their excessive online behaviors in real life, little is known about the patho-physiological and cognitive mechanisms responsible for Internet addiction. Due to the lack of methodologically adequate research, it is currently impossible to recommend any evidence-based treatment of Internet addiction.

2017-10-01

Internet-delivered cognitive-behavioral therapy (ICBT) has been established as both efficacious and effective in reducing symptoms of social anxiety. However, most research has been conducted in controlled settings, and little is known regarding the utility of such programs in an open-access format. The present study examined the use, adherence, and effectiveness of Joyable, an open-access, Internet-delivered, coach-supported CBT-based intervention for social anxiety. Participants were 3,384 registered users (Mage [SD] = 29.82 [7.89]; 54% male) that created an account between 2014 and 2016. Characteristics of use, factors related to attrition and adherence, and within-group outcomes were examined. The primary outcome measure was the Social Phobia Inventory. On average, participants remained in the program for 81.02 days (SD = 60.50), during which they completed 12.14 activities (SD = 11.09) and 1.53 exposures (SD = 3.18). About half (57%) had contact with a coach. Full adherence to the program was achieved by 16% of participants, a rate higher than previously published open-access studies of ICBT. Social anxiety symptoms were significantly reduced for participants that engaged in the program, with medium within-group effects from baseline through the cognitive restructuring module (d = 0.63-0.76) and large effects from baseline through the exposure module (d = 1.40-1.83). Response rates were high (72%). Exposures and coach contact were significant predictors of retention and outcome. This open-access online CBT-based program is effective in reducing social anxiety symptoms and has the potential to extend Internet-based mental health services to socially anxious individuals unwilling or unable to seek face-to-face evidence-based therapy.

Xu, Ronghua; Chen, Yu; Blasch, Erik; Chen, Genshe

2018-05-01

The prevalence of Internet of Things (IoTs) allows heterogeneous embedded smart devices to collaboratively provide intelligent services with or without human intervention. While leveraging the large-scale IoT-based applications like Smart Gird and Smart Cities, IoT also incurs more concerns on privacy and security. Among the top security challenges that IoTs face is that access authorization is critical in resource and information protection over IoTs. Traditional access control approaches, like Access Control Lists (ACL), Role-based Access Control (RBAC) and Attribute-based Access Control (ABAC), are not able to provide a scalable, manageable and efficient mechanisms to meet requirement of IoT systems. The extraordinary large number of nodes, heterogeneity as well as dynamicity, necessitate more fine-grained, lightweight mechanisms for IoT devices. In this paper, a federated capability-based access control (FedCAC) framework is proposed to enable an effective access control processes to devices, services and information in large scale IoT systems. The federated capability delegation mechanism, based on a propagation tree, is illustrated for access permission propagation. An identity-based capability token management strategy is presented, which involves registering, propagation and revocation of the access authorization. Through delegating centralized authorization decision-making policy to local domain delegator, the access authorization process is locally conducted on the service provider that integrates situational awareness (SAW) and customized contextual conditions. Implemented and tested on both resources-constrained devices, like smart sensors and Raspberry PI, and non-resource-constrained devices, like laptops and smart phones, our experimental results demonstrate the feasibility of the proposed FedCAC approach to offer a scalable, lightweight and fine-grained access control solution to IoT systems connected to a system network.

On the scalability of uncoordinated multiple access for the Internet of Things

KAUST Repository

Chisci, Giovanni

2017-11-16

The Internet of things (IoT) will entail massive number of wireless connections with sporadic traffic patterns. To support the IoT traffic, several technologies are evolving to support low power wide area (LPWA) wireless communications. However, LPWA networks rely on variations of uncoordinated spectrum access, either for data transmissions or scheduling requests, thus imposing a scalability problem to the IoT. This paper presents a novel spatiotemporal model to study the scalability of the ALOHA medium access. In particular, the developed mathematical model relies on stochastic geometry and queueing theory to account for spatial and temporal attributes of the IoT. To this end, the scalability of the ALOHA is characterized by the percentile of IoT devices that can be served while keeping their queues stable. The results highlight the scalability problem of ALOHA and quantify the extend to which ALOHA can support in terms of number of devices, traffic requirement, and transmission rate.

College Students' Use of the Internet

1999-02-01

Full Text Available Over the last several years there has been mounting concern about children being exposed to sex-related material on the Internet. Concern about pornography and obscenity is widespread and this concern has spawned a host of products to block or filter content. The notorious Time magazine article (July 3, 1995 "Cyberporn"--which Time later acknowledged had doubtful credibility (July 24, 1995--undoubtedly inflamed this trend. The article, which asserted that much of traffic on the Internet dealt with pornography, was based on the largely discredited research of a Carnegie Mellon undergraduate student who examined 32 alt.binaries newsgroups on Usenet, not the Internet. Nonetheless, the article was fodder for the Communications Decency Act of 1996. While the Supreme Court struck down the Act, pending bills such as the "Safe Schools Internet Act" (H.R. 3177 would require all public libraries and schools that receive federal funds for Internet access to install blocking software to restrict minors' access to "inappropriate" material. Other pending bills would punish commercial online distributors for access to material they do not directly control and require service providers to offer blocking software to customers. While most students who use computers in university computer labs are legally adults, many are not. If laws restrict access to minors, there will be a host of technical problems to provide access to scholars and adult students. Labs are open spaces where students come and go, using computers for many purposes but only part of the time for Internet access. Determining policies and creating procedures to implement and monitor policies will entail considerable resources for something that may not be a serious problem and something that cannot be effectively controlled with filtering software. It could require students to present identification to prove they are adults in order to access certain computer resources, not to mention the

By the same token, whether Internet/language self-efficacy would mediate the effects of Internet/language anxiety on the intention of the Internet site use is also examined. A valid sample of 368 undergraduates was tested in this study. The path analysis results mostly supported the model tested. The results display that the anxiety of language and Internet use have significantly influenced self-efficacy of Internet use and language, respectively. Anxiety about language and Internet use have also significantly influenced the intention to use Internet sites individually. Furthermore, language self-efficacy has significantly influenced the intention to use Internet sites, but Internet self-efficacy has not. The implications are discussed at the end of the paper.

Building it together: collaboration in university-based open access book publishing

Directory of Open Access Journals (Sweden)

Dr Andrea Hacker

2014-04-01

Full Text Available Open access (OA book publishing in the humanities and social sciences is becoming technically more feasible and financially more desirable. After securing funding for the development of a business model based on a pilot book series, the University of Heidelberg is joining this development and building an infrastructure to publish OA books on campus. The challenges facing such new publishing outlets are considerable. This article argues that the best strategy to build the prestige, affordability and competitiveness necessary to succeed is collaboration. Accomplishing this within the OA community will prove less difficult than extending collaboration beyond it because many agencies and individuals still lack information about, and are often unconvinced of, the merits of open access. The key lies in offering excellence in manuscript development to revitalize the most important collaboration of all: that between publisher and author.

Dezelić, Gjuro

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

Critical care physicians may benefit from immediate access to medical reference material. We evaluated the feasibility and potential benefits of a handheld computer based knowledge access system linking a central academic intensive care unit (ICU) to multiple community-based ICUs. Four community hospital ICUs with 17 physicians participated in this prospective interventional study. Following training in the use of an internet-linked, updateable handheld computer knowledge access system, the physicians used the handheld devices in their clinical environment for a 12-month intervention period. Feasibility of the system was evaluated by tracking use of the handheld computer and by conducting surveys and focus group discussions. Before and after the intervention period, participants underwent simulated patient care scenarios designed to evaluate the information sources they accessed, as well as the speed and quality of their decision making. Participants generated admission orders during each scenario, which were scored by blinded evaluators. Ten physicians (59%) used the system regularly, predominantly for nonmedical applications (median 32.8/month, interquartile range [IQR] 28.3-126.8), with medical software accessed less often (median 9/month, IQR 3.7-13.7). Eight out of 13 physicians (62%) who completed the final scenarios chose to use the handheld computer for information access. The median time to access information on the handheld handheld computer was 19 s (IQR 15-40 s). This group exhibited a significant improvement in admission order score as compared with those who used other resources (P = 0.018). Benefits and barriers to use of this technology were identified. An updateable handheld computer system is feasible as a means of point-of-care access to medical reference material and may improve clinical decision making. However, during the study, acceptance of the system was variable. Improved training and new technology may overcome some of the barriers we

Using Internet of Things technologies for wireless sensor networks

Science.gov (United States)

Martinez, K.; Hart, J. K.; Basford, P. J.; Bragg, G. M.; Ward, T.

2013-12-01

Numerous authors have envisioned the future internet where anything will be connected: the Internet of Things (IoT). The idea is an extrapolation of the spread of networked devices such as phones, tablets etc. Each device is expected to have its own Internet address and thus be easy to access. The key building blocks of any IoT system are networking, hardware platforms and node software - so they are similar to wireless sensor network requirements. Most existing IoT demonstrators and applications have been gadget-style objects where power and connectivity problems are not too restricting. Environmental sensor networks can benefit from using some of the technologies involved in IoT development. However it is expected that tuning the networking and power management will be necessary to make them as efficient as state of the art wireless sensor networks. Some IoT assumptions such as always-connected nodes and full IP capability need to be considered. This paper will illustrate the advantages and disadvantages of IoT techniques for environment sensing drawing on a range of employment scenarios. We also describe a glacial 'Internet of things' project, which aims to monitor glacial processes. In particular we describe the IoT developments in a deployment in Iceland to examine glacier seismicity, velocity and provide camera images.

2007-12-01

Full Text Available The recognized potential of technology to improve education has led to several initiatives to foster effective use and integration in the curriculum. The Internet as a new invented technology holds the greatest promise humanity has known for learning and universal access to quality education. It allows students to broaden their academic experience, access important information and communicate to others within academic community. In the light of these therefore, this study examined undergraduate’s uses of the Internet and its implications on their academic performance at the University of Botswana, Gaborone. Three hundred and six undergraduate students from thirteen systematically selected departments formed the study sample. A modified Internet Use scale was used to gather data for the study. The data collected was analysed using descriptive statistics, chi-square and Friedman test. The results indicate that: majority of the respondents (66% access the Internet 1-5 hours per week, 33.3% of respondents access the Internet 6-20 hours per week and 0.7% of respondents access the Internet between 21-25 hours per week. Moreover, most respondents use the Internet for the purpose of obtaining course related information. The results also reveal that Internet contributes significantly to academic performance of the respondents. To enhance and optimise the use of the Internet so that learning can take place at any time and anywhere, providing more access to computers and the Internet on campus constitutes the major recommendations. Future areas of research could include determining variations in Internet use by students from different disciplines, determining the nature and relationships between Internet use and academic performance.

Sitewide task team report for Internet policy

Energy Technology Data Exchange (ETDEWEB)

Aichele, D.R.

1995-03-01

The Internet is rapidly becoming the standard for communications, information transfer, and information sharing among U.S. Department of Energy (DOE) organizations. It has long been used by the major laboratories, but is now beginning to be used by headquarters staff to communicate with field offices and contractors and as the access point to DOE`s repositories of information. It will soon become key to efficient conduct of operations. Sites without effective access to the Internet will have to rely on secondary, less effective communications. Therefore, the task team believes it is essential that Hanford become a full participant in utilizing this resource. To make this happen an effective access and delivery infrastructure must be provided to DOE and contractor staff and standard ways of doing business on the Internet are required. Much of the technology exists today for robust electronic interchange of information. The use of this technology needs to be expanded and coordinated throughout the DOE and Hanford contractor community. As the use of Internet within DOE is advancing rapidly, it will become the preferred method for communication and information sharing within 5 years. The conclusion of the Internet Inter-Contractor task team is that the use of the Internet is essential to communicate as well as provide and obtain information and knowledge. The Hanford Site must foster, support, and implement necessary changes to the technology infrastructure to improve user access, maintain security, and assure we are effective participants in the networked community.

The Internet and the Nigerian Woman: A Case of Female Undergraduates

Directory of Open Access Journals (Sweden)

Joseph Wilson

2015-06-01

Full Text Available The Internet has drastically changed information and knowledge sharing processes globally. It is a widely accepted medium for transformation and empowerment. Individuals, groups, communities and nations, including women in their quest for a gender sensitive society have adopted the Internet as a viable tool. However, despite the countless benefits of this important tool of communication, research, entertainment, publishing, and business, there are challenges that affect Internet access and use among female students at the University of Maiduguri, Nigeria. This paper examines Internet access and use among female undergraduates at a Nigerian University. Selected female undergraduates completed questionnaires. The findings shows that the university computer centre (University Cyber Café is the major Internet access point among the respondents. Research (information searches and learning ranked first in the uses of the Internet among respondents, with financial constraints as the major challenge to access and use of the Internet. Respondents found women-related websites useful. They derive a certain gratification from these sites. However, most respondents do not post or contribute material or information on the web. Their interaction with the web involves mostly downloading. The study concludes that Internet access and use status among female students at the University of Maiduguri and women in general would be greatly enhanced if women organizations concentrated on addressing the challenges identified in this study. Attention should be paid to this category of women (university students who have the educational capabilities and Internet potential to impact women empowerment efforts.

Purpose: Studies describing the use of the Internet by radiation oncology patients are lacking. This multi-institutional study of cancer patients presenting to academic (AC), community (CO) and veterans (VA) radiation oncology centers was designed to analyze the use of the Internet, predictive factors for utilization, and barriers to access to the Internet. Materials and Methods: A questionnaire evaluating the use of the Internet was administered to 921 consecutive patients presenting to radiation oncology departments at AC, CO and VA Medical Centers. The study included 436 AC patients (47%), 284 CO patients (31%), and 201 VA patients (22%). A computer was available at home to 427 patients (46%) and 337 patients (37%) had Email access. The mean age of the patient population was 64 years (range=14-93). Males represented 70% of the patient population. The most common diagnoses included prostate cancer (33%), breast cancer (13%), and lung cancer (11%). Results: Overall, 265/921 patients (29%) were using the Internet to find cancer related information. The Internet was used by 42% of AC patients, 25% of CO patients and only 5% of VA patients (p<.0001). A computer was available at home in 62% AC vs. 45% CO vs. 12% VA patients (p<.0001). Patients < 60 years were much more likely to use the Internet than older patients (p<.0001). Most of the Internet users considered the information either very reliable (22%) or somewhat reliable (70%). Most patients were looking for information regarding treatment of their cancer (90%), management of side effects of treatment (74%), alternative/complementary treatments (65%) and clinical trials (51%). Unconventional medical therapies were purchased over the Internet by 12% of computer users. Products or services for the treatment or management of cancer were purchased online by 12% of Internet users. Conclusion: A significant number of cancer patients seen in radiation oncology departments at academic and community medical centers

Northrup, Jason C; Lapierre, Coady; Kirk, Jeffrey; Rae, Cosette

2015-07-28

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.

Internet addiction: definition, assessment, epidemiology and clinical management.

Science.gov (United States)

Shaw, Martha; Black, Donald W

2008-01-01

Internet addiction is characterized by excessive or poorly controlled preoccupations, urges or behaviours regarding computer use and internet access that lead to impairment or distress. The condition has attracted increasing attention in the popular media and among researchers, and this attention has paralleled the growth in computer (and Internet) access. Prevalence estimates vary widely, although a recent random telephone survey of the general US population reported an estimate of 0.3-0.7%. The disorder occurs worldwide, but mainly in countries where computer access and technology are widespread. Clinical samples and a majority of relevant surveys report a male preponderance. Onset is reported to occur in the late 20s or early 30s age group, and there is often a lag of a decade or more from initial to problematic computer usage. Internet addiction has been associated with dimensionally measured depression and indicators of social isolation. Psychiatric co-morbidity is common, particularly mood, anxiety, impulse control and substance use disorders. Aetiology is unknown, but probably involves psychological, neurobiological and cultural factors. There are no evidence-based treatments for internet addiction. Cognitive behavioural approaches may be helpful. There is no proven role for psychotropic medication. Marital and family therapy may help in selected cases, and online self-help books and tapes are available. Lastly, a self-imposed ban on computer use and Internet access may be necessary in some cases.

Tagging: An Organization Scheme for the Internet

Directory of Open Access Journals (Sweden)

Marijke A. Visser

2010-03-01

Full Text Available How should the information on the Internet be organized? This question and the possible solutions spark debates among people concerned with how we identify, classify, and retrieve Internet content. This paper discusses the benefits and the controversies of using a tagging system to organize Internet resources. Tagging refers to a classification system where individual Internet users apply labels, or tags, to digital resources. Tagging increased in popularity with the advent of Web 2.0 applications that encourage interaction among users. As more information is available digitally, the challenge to find an organizational system scalable to the Internet will continue to require forward thinking. Trained to ensure access to a range of informational resources, librarians need to be concerned with access to Internet content. Librarians can play a pivotal role by advocating for a system that supports the user at the moment of need. Tagging may just be the necessary system.

Access Denied! Contrasting Data Access in the United States and Ireland

Directory of Open Access Journals (Sweden)

Grogan Samuel

2016-07-01

Full Text Available The ability of an Internet user to access data collected about himself as a result of his online activity is a key privacy safeguard. Online, data access has been overshadowed by other protections such as notice and choice. This paper describes attitudes about data access. 873 US and Irish Internet users participated in a survey designed to examine views on data access to information held by online companies and data brokers. We observed low levels of awareness of access mechanisms along with a high desire for access in both participant groups. We tested three proposed access systems in keeping with industry programs and regulatory proposals. User response was positive. We conclude that access remains an important privacy protection that is inadequately manifested in practice. Our study provides insight for lawmakers and policymakers, as well as computer scientists who implement these systems.

2004-10-01

This study assessed Internet use and attitudes toward illicit use of the Internet in a sample of Russian college students. A sample comprised of 198 students was recruited from a university in Moscow. Each participant completed a survey assessing demographic characteristics, Internet use, and attitudes towards engaging in illicit behaviors over the Internet. About half of the students reported that they used the Internet at least several times a year, with 8% reporting daily use of the Internet. Among Internet users, most reported having Internet access either at home or at a friends' home, and 16 % reported having Internet access from work, school, or a computer center. Among Internet users, the main purpose was for school-related activities (60%), followed by e-mail (55%), entertainment (50%), chatting (24%), and searching for pornography (6%). Although most students thought it was inappropriate to read someone else's e-mail, use someone else's password or credit card information without their permission, or break into someone's computer, many students did endorse those illicit behaviors. Over a fifth of the students reported that they knew hackers. Forty three percent of students agreed that people make too much fuss about watching videos, movies or downloading music on the Internet without paying. Males were more likely than females to report using the Internet for entertainment purposes (p = 0.006) and were more likely to agree that it was okay to break into someone's computer (p = 0.04). The results of this study suggest that these Russian college students predominately use the Internet to help with their schoolwork, to communicate with others, and for entertainment. These results also suggest that interventions may be useful to change attitudes endorsing illicit uses of the Internet.

2013-03-01

The purpose of this study is to investigate the internet use of Turkish adolescents, with a (particular) focus on the risk of Internet addiction. A web-based questionnaire was completed by a total of 4,311 adolescents attending public high schools in grades 9-12, in a small-sized city in western Turkey. Ages ranged from 15 to 19 years, 54 percent were female and 46 percent male. The questionnaire included items on sociodemographic information, Internet usage, and a Turkish version of the Young's Internet Addiction Test. The data were analyzed in SPPS 15.0 program using the t test, the Mann-Whitney U test, correlation and hierarchic regression analysis. The findings show that, regardless of gender, Facebook ranked highest in the classification of students' purpose of Internet use; it was also found that females mainly used the Internet for communication, whereas males were more interested in playing online games and reading newspapers and magazines. The results of hierarchic regression analysis indicated that the significant predictors of the internet addiction were the presence of Internet access at home, gender, and family income levels.

An increasing number of breast cancer patients are accessing the Internet for medical information. A survey was administered to breast cancer patients and their families attending follow-up outpatient clinics in a comprehensive cancer care center to explore their frequency of Internet use, their motivation for online activity, the type of information they sought, and the perceived impact of the information they found on the Internet on their medical care. The survey was conducted over a 4-month period. A total of 107 surveys were returned. Seventy-nine of these (74%) were from patients while 28 (26%) were from family members and friends. Thirty-four of the patient responses (43%) indicated that the patient had used the Internet to look for cancer-related information. Patients who had used the Internet to access cancer-related information were significantly younger (P = 0.007), better educated (P = 0.027), and less satisfied with the amount of treatment-related information given by caregivers than those patients who had not used the Internet to access cancer-related information (P = 0.032). The majority of patient Internet users desired more information on their cancer and its treatment (91%), looked up information that was presented to them by their clinicians (66%), researched other treatment options (63%), and obtained more information on "alternative treatments" (63%). Patient Internet users generally found the cancer-related information on the Internet to be useful, and the majority discussed Internet-derived information with their health care providers and perceived that clinicians listened to such information. However, 53% were undecided about the trustworthiness of the medical information obtained via the Internet. Internet nonusers commonly lacked Internet access (53%) or were unfamiliar with the Internet (33%), but few (13%) distrusted Internet-derived information. This exploratory study underscores the need for more research in this area, specifically

Vaccaro, Monica; Hart, Tessa; Whyte, John; Buchhofer, Regina

2007-03-01

To examine experiences among individuals in the USA with traumatic brain injury (TBI) regarding their access to and use of the Internet, problems encountered, and desire for improved Internet access and skills. An in-depth survey was administered as a semi-structured interview to 80 individuals at least 3 months post moderate to severe TBI. Two-thirds of respondents reported having a computer at home, but only half had access to the Internet. Fewer than half were Internet users, as compared to 60% users in the USA population at the time of the survey. However, Internet activities engaged in by users in this sample were comparable to those of the overall population. There was a strong interest in using the Internet among non-users. Most respondents expressed a strong desire for coaching or other training to enhance or develop Internet skills. Reported reasons for Internet non-use in this sample were lack of access and knowledge, versus lack of interest as in the general population. The high interest in using and learning more about the Internet supports the development of interventions to mprove Internet skills for people with TBI.

Toward Accessing Spatial Structure from Building Information Models

Science.gov (United States)

Schultz, C.; Bhatt, M.

2011-08-01

Data about building designs and layouts is becoming increasingly more readily available. In the near future, service personal (such as maintenance staff or emergency rescue workers) arriving at a building site will have immediate real-time access to enormous amounts of data relating to structural properties, utilities, materials, temperature, and so on. The critical problem for users is the taxing and error prone task of interpreting such a large body of facts in order to extract salient information. This is necessary for comprehending a situation and deciding on a plan of action, and is a particularly serious issue in time-critical and safety-critical activities such as firefighting. Current unifying building models such as the Industry Foundation Classes (IFC), while being comprehensive, do not directly provide data structures that focus on spatial reasoning and spatial modalities that are required for high-level analytical tasks. The aim of the research presented in this paper is to provide computational tools for higher level querying and reasoning that shift the cognitive burden of dealing with enormous amounts of data away from the user. The user can then spend more energy and time in planning and decision making in order to accomplish the tasks at hand. We present an overview of our framework that provides users with an enhanced model of "built-up space". In order to test our approach using realistic design data (in terms of both scale and the nature of the building models) we describe how our system interfaces with IFC, and we conduct timing experiments to determine the practicality of our approach. We discuss general computational approaches for deriving higher-level spatial modalities by focusing on the example of route graphs. Finally, we present a firefighting scenario with alternative route graphs to motivate the application of our framework.

2012-05-01

Internet-based technologies such as personal health records and patient portals are increasingly viewed as essential for enhancing patient-provider communication and patient-centered care. We examined how primary care patients use the Internet, particularly patient characteristics associated with Internet use. We surveyed patients in five primary care clinic waiting rooms. Patients who had used email or the Internet in the past month (Internet users) were asked how often they used a computer for a variety of tasks. Participants who reported not using the Internet were asked about several potential barriers to Internet use. We approached 713 patients, and 638 (89.6%) completed questionnaires; 499 (78%) were Internet users and 139 (22%) were non-users. Lack of computer access and not knowing how to use email or the Internet were the most common barriers to Internet use. Younger age, higher education and income, better health, and absence of a chronic illness were associated with Internet use. After controlling for age and other variables, chronic illness was no longer associated with Internet use. Internet use was high among our primary care patients. The major factor associated with Internet use among patients with chronic conditions was their age. If older adults with chronic illness are to reap the benefits of health information technology, their Internet access will need to be improved. Institutions that are planning to offer consumer health information technology should be aware of groups with lower Internet access.

Mayben, J K; Giordano, T P

2007-10-01

Patients are increasingly using the Internet to obtain health-related information, communicate with providers and access research. Use of the Internet to obtain health-related information by low-income patients recently diagnosed with HIV infection has not been examined. In 2005, we surveyed 126 low-income patients diagnosed with HIV infection within the last three years. Eighty-five percent of the patients wereInternet to access information about HIV, 52% had never used the Internet, 28% had never used it to obtain health-related information and only 18% had done so at least monthly for the last six months. Two-thirds of the population studied would need instruction on how to use the Internet. In multivariable regression, 2004 income > or =$15,000 predicted monthly Internet use to obtain health-related information. Older age, heterosexual intercourse as HIV risk factor and inadequate health literacy were independent predictors of needing instruction. The low-income population with HIV infection lags behind the general population in Internet access and may not benefit from Internet-dependent advances in health communication, including HIV-related interventions.

Srinivas, M; Inumpudi, A; Mitra, D K

1998-12-01

The Internet, which has truly united the world, is an extensive network of inter-linked computers storing immense bytes of information that can be accessed by anyone, transcending all barriers. The paediatric surgery Internet consists of exponentially growing material that deals with information specifically for paediatric surgeons and patients of the paediatric age group. We reviewed the methods available to take advantage of this network to enable busy paediatric surgeons to accrue the benefits easily and efficiently rather than be lost in the information ocean by surfing individually. By getting connected to the Internet, the paediatric surgeon gains enormous information that can be useful for patient care. The Internet has revolutionised scientific publications by virtue of its fast and accurate transmission of manuscripts. Paediatric surgeons can send manuscripts by this channel and also access journals, obviating the inherent lag period of communication by post.

Dynamic Spectrum Access for Internet of Things Service in Cognitive Radio-Enabled LPWANs.

Science.gov (United States)

Moon, Bongkyo

2017-12-05

In this paper, we focus on a dynamic spectrum access strategy for Internet of Things (IoT) applications in two types of radio systems: cellular networks and cognitive radio-enabled low power wide area networks (CR-LPWANs). The spectrum channel contention between the licensed cellular networks and the unlicensed CR-LPWANs, which work with them, only takes place within the cellular radio spectrum range. Our aim is to maximize the spectrum capacity for the unlicensed users while ensuring that it never interferes with the licensed network. Therefore, in this paper we propose a dynamic spectrum access strategy for CR-LPWANs operating in both licensed and unlicensed bands. The simulation and the numerical analysis by using a matrix geometric approach for the strategy are presented. Finally, we obtain the blocking probability of the licensed users, the mean dwell time of the unlicensed user, and the total carried traffic and combined service quality for the licensed and unlicensed users. The results show that the proposed strategy can maximize the spectrum capacity for the unlicensed users using IoT applications as well as keep the service quality of the licensed users independent of them.

Internet use in radiology: results of a nationwide survey

Energy Technology Data Exchange (ETDEWEB)

Vorbeck, F; Zimmermann, C; Vorbeck-Meister, I; Kainberger, F; Imhof, H

Purpose: To determine the number of radiologists who currently have Internet access, their use patterns on the Internet for Radiology purposes, the web sites they would recommend, and the potential site access to the Internet that they would like to see in the future. In addition, this study analyzed the best way to find nationwide radiological sites and their content. Materials and Methods: In a nationwide survey, 854 Austrian radiologist were asked to fill out and return a questionnaire about Internet access, current problems, current and future use, which web site they recommend, and about the use of e-mail. Next, the available nationwide radiological sites were searched with seven major search engines using 37 different keywords, as well as by category search, and by searching for links on the homepages of the radiological departments of all Universities of Austria. Then, the offered information of the founded pages was classified in categories. Results: Of the 210 (24.6%) radiologists who returned the questionnaire, 154 (73%) had Internet access. Time expenditure was considered the main problem using the Internet. The Internet was used for literature research by 69% of the radiologists with Internet access, for e-mail by 60%, and for congress information by 57%. In future, 43% would like to read electronic journals more often and 39% would like to use the web more intensively for scientific congresses. At the present time, we found 17 radiological web sites in Austria. The most promising way to find these sites was to use the search engines Alta Vista and Hotbot. Fifteen (88%) sites offered information for patients, seven (41%) for radiologists, five (29%) for students, and four (24%) for researchers. Summary: Many radiologists in Austria already have Internet access, although time expenditure was considered the main problem with Internet use. Survey responses showed a need for electronic journals. To our point of view, Universities and radiological societies

Heaton, Karen; Combs, Bryan; Griffin, Russell

2017-06-01

Because of their social isolation, irregular and unpredictable schedules, limited access to health care, and long periods of travel, long-haul truckers may benefit from the use of mobile health applications on Internet-capable devices. The purpose of this study was to determine Internet access and usage among a sample of long-haul truck drivers. In this cross-sectional study, truck drivers completed a pencil and paper survey with questions on demographics, work and health histories, and Internet access and usage for both personal and job reasons. A total of 106 truck drivers were recruited from trucking industry trade shows, by word of mouth, and directly from trucking companies. Overall, the truck drivers' use of the Internet was limited. Their usage for personal and job-related reasons differed. Social connectivity and access to health and wellness information were important during personal usage time. Job-related Internet use was highly practical, and applied to seeking information for directions and maps, fuel stops and pricing, and communicating with employers or transmitting documents. Age and experience were associated with Internet use. Younger, less-experienced drivers used the Internet more than older, experienced drivers. Targeted mobile health messaging may be a useful tool to inform truck drivers of health conditions and plans, and may provide links to primary care providers needing to monitor or notify drivers of diagnostic results or treatment plans.

2010-05-01

The Internet may provide an alternative option for rural lung cancer patients who lack access to on-site cancer support; however, Internet access and use among rural patients is unknown. An anonymous waiting-room survey was administered to all outpatient cardiothoracic surgery patients over 3 mo. Survey questions included age, gender, and diagnosis, possession of a home computer and Internet service, estimated Internet use, and use of the Internet for health information. Patients with known or suspected lung cancer were asked to indicate their interest in on-site and Internet cancer support. There were 597 returned surveys (response rate 96%). The mean age was 64.6 y (SE 0.55), and 58% were men. Diagnoses included known or possible lung cancer (15.4%), lung disease (9.5%), heart disease (30.4%), other diagnoses (13.9%), and undetermined (30.6%). There were 343 patients (57.4%) with a home computer and 299 (50.1%) with home Internet service. Average Internet use was 8.5 h per wk (n = 298), and 225 patients used the Internet for health information. Of the 92 patients with lung cancer, 10 indicated interest in on-site support services while 37 expressed interest in Internet-based support. Based on survey results, a slight majority of rural patients have a home computer and Internet access. Internet use for health information appears relatively common. Overall interest for support services among lung cancer patients appears modest with a greater interest in Internet-based services compared with on-site support. Copyright 2010 Elsevier Inc.

The purpose of this paper was to investigate whether information about radiography careers that was placed on the Internet was accessible, accurate, understandable, comprehensive, abundant and attractive to a sample of school children. Additionally this paper investigated whether the sample of school children had access to the Internet and whether they knew how to use it. A self-administered questionnaire was used to assess views on the radiography information, Internet access and knowledge of how to use the Internet. Questionnaire data were then analysed and the Websites were ranked. Thirty-three Websites were evaluated; these gave varying qualities of information with questionnaire scores ranging from 188 to 76. This investigation showed that there are many Websites available about radiography as a career. The site that performed most successfully overall in this evaluation was the NHS Careers Website. This site was ranked highest for the design section but the University of Salford's Website performed top for content

The objective of this study was to assess perceived Internet health literacy of HIV-positive people before and after an Internet health information educational intervention. We developed a 50-min educational intervention on basic computer skills and online health information evaluation. We administered a demographic survey and a validated health literacy survey (eHEALS) at baseline, immediately after, and 3 months the class. Changes in scores between the surveys were analysed. Eighteen HIV-positive participants were included in the final analysis. Before the intervention, most respondents' assessment of their ability to access Internet health information was unfavourable. Post-intervention, the majority of respondents agreed or strongly agreed they were able to access and identify Internet health information resources. The increase in self-assessed skill level was statistically significant for all eight items eHEALS (P Internet health information educational intervention HIV-positive people with baseline low perceived Internet health literacy significantly improves confidence in finding and using Internet health information resources. Studies with larger numbers of participants should be undertaken to determine if brief interventions improve self-care, patient outcomes and use of emergency services. © 2010 The authors.

IPv6 (Internet Protocol version 6) heterogeneous networking infrastructure for energy efficient building

International Nuclear Information System (INIS)

Ben Saad, Leila; Chauvenet, Cedric; Tourancheau, Bernard

2012-01-01

In the context of increasing developments of home, building and city automation, Power Line Communication (PLC) networking is called for unprecedented usage, especially for energy efficiency improvement. Our view of the future building networking infrastructure places PLC as the central point. We point that while Wireless Sensor Network (WSN) is necessary in the sensor and actuator networking infrastructure, PLC is mandatory for the smart-grid metering and command infrastructure. PLC will also serve the sensor/actuator infrastructure when the energy requirement of the probing system itself cannot be fulfilled by autonomous battery and harvesting based nodes. PLC may also provide the numerous bridges necessary to sustain a long lifetime (years) with the battery based WSN part of the infrastructure. This new role of PLC networking will be possible only if the interoperability between all media and technology is made possible. Thanks to the converging design of Internet Protocol version 6 (IPv6) networking layers, we show that such a full inter-interoperability is already possible even in very tiny constrained networking devices. Moreover, the low power PLC technology used in our experiments will be able to provide this smart grid monitoring without impacting noticeably the overall energy balance of the monitored system.

The impact of Internet-based specific activities on the perceptions of Internet addiction, quality of life, and excessive usage: A cross-sectional study.

Pontes, Halley M; Szabo, Attila; Griffiths, Mark D

2015-06-01

Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

Security incidents on the Internet, 1989--1995

Energy Technology Data Exchange (ETDEWEB)

Howard, J.D.

1995-12-31

This paper presents an analysis of trends in Internet security based on an investigation of 4,299 Internet security-related incidents reported to the CERT{reg_sign} Coordination Center (CERT{reg_sign}/CC) from 1989 through 1995. Prior to this research, knowledge of actual Internet security incidents was limited and primarily anecdotal. This research: (1) developed a taxonomy to classify Internet attacks and incidents, (2) organized, classified, and analyzed CERT{reg_sign}/CC incident records, (3) summarized the relative frequency of the use of tools and vulnerabilities, success in achieving access, and results of attacks, (4) estimated total Internet incident activity, (5) developed recommendations for Internet users and suppliers, and (6) developed recommendations for future research. With the exception of denial-of-service attacks, security incidents were found to be increasing at a rate less than Internet growth. Estimates showed that most, if not all, severe incidents were reported to the CERT{reg_sign}/CC, and that more than one out of three above average incidents (in terms of duration and number of sites) were reported. Estimates also indicated that a typical Internet site was involved in, at most, around one incident (of any kind) per year, and a typical Internet host in, at most, around one incident in 45 years. The probability of unauthorized privileged access was around an order of magnitude less likely. As a result, simple and reasonable security precautions should be sufficient for most Internet users.

Internet health information in the patient-provider dialogue.

Science.gov (United States)

Hong, Traci

2008-10-01

A patient discussing Internet health information with a health care provider (referred to as "patient-provider communication about Internet health information") can contribute positively to health outcomes. Although research has found that once Internet access is achieved, there are no ethnic differences in Internet health information seeking, it is unclear if there are ethnic differences in patient-provider communication about Internet health information. To help fill this gap in the literature, the National Cancer Institute's Health Information National Trends Survey 2005 was analyzed with Stata 9. Two sets of logistic regression analyses were conducted, one for a subsample of Internet users (n = 3,244) and one for a subsample of Internet users who are first-generation immigrants (n = 563). The dependent variable was patient-provider communication about Internet health information, which assessed whether survey participants had discussed online health information with a health care provider. The predictor variables included trust of health care provider, trust of online health information, Internet use, health care coverage, frequency of visits to health care provider, health status, and demographics. Among all Internet users, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. Similarly, among Internet users who are immigrants, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. While the digital divide is narrowing in terms of Internet access, racial differences in patient-provider communication about Internet health information may undermine the potential benefits of the information age.

There is substantial literature on the impact of the mass media on children's and adolescents' health and development. The question of what role new technology plays in the media's influence is now a subject of both review and discussion, particularly regarding health risks and intervention. This article takes a brief look at online usage and the theoretical mechanisms that might make Internet access more problematic in terms of risks, compared with more traditional media such as television and film. One of these risks, known today as cyberbullying or Internet harassment, is scrutinized in detail. Copyright © 2012 Elsevier Inc. All rights reserved.

Some addictions cannot be connected with substance abuse (pathological gambling, video games playing, binge eating, compulsive physical activity, emotional relationship addiction, TV addiction). Since 1995, Internet addiction has been accepted as a clinical entity with profound negative effect on social, familial, educational and economical personal functioning. The diagnosis of Internet addiction could be established if the person spends more than 38 hours per week on the Internet exempting online professional needs. Basic symptoms are the increased number of hours spent in front of the computer along with the Internet use, development of abstinent syndrome if the Internet access is prohibited, sleep inversion, neglect of basic social requirements and personal hygiene, many somatic symptoms developed due to prolonged sitting or monitor watching, dissocial behaviour. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction.

2012-01-01

The Internet lets us share perfect copies of our work with a worldwide audience at virtually no cost. We take advantage of this revolutionary opportunity when we make our work "open access": digital, online, free of charge, and free of most copyright and licensing restrictions. Open access is made possible by the Internet and copyright-holder consent, and many authors, musicians, filmmakers, and other creators who depend on royalties are understandably unwilling to give their consent. But for 350 years, scholars have written peer-reviewed journal articles for impact, not for money, and are free to consent to open access without losing revenue. In this concise introduction, Peter Suber tells us what open access is and isn't, how it benefits authors and readers of research, how we pay for it, how it avoids copyright problems, how it has moved from the periphery to the mainstream, and what its future may hold. Distilling a decade of Suber's influential writing and thinking about open access, this is the indispe...

Patient portals have shown potential for increasing health care quality and efficiency. Internet access and other factors influencing patient portal use could worsen health disparities. Observational study of adults with 1 or more visits to the outpatient clinics of an urban public health care system from 2012 to 2015. We used mixed effects logistic regression to evaluate the association between broadband internet access and (1) patient portal initiation (whether a patient logged in at least 1 time) and (2) messaging, controlling for demographic and neighborhood characteristics. There were 243 248 adults with 1 or more visits during 2012-2015 and 70 835 (29.1%) initiated portal use. Portal initiation was 34.1% for whites, 23.4% for blacks, and 23.8% for Hispanics, and was lower for Medicaid (26.5%), Medicare (23.4%), and uninsured patients (17.4%) than commercially insured patients (39.3%). In multivariate analysis, both initiation of portal use (odds ratio [OR] = 1.24 per quintile, 95% confidence interval [CI], 1.23-1.24, P  internet access. The majority of adults with outpatient visits to a large urban health care system did not use the patient portal, and initiation of use was lower for racial and ethnic minorities, persons of lower socioeconomic status, and those without neighborhood broadband internet access. These results suggest the emergence of a digital divide in patient portal use. Given the scale of investment in patient portals and other internet-dependent health information technologies, efforts are urgently needed to address this growing inequality. © The Author 2017.

Identifying problematic Internet users: development and validation of the Internet Motive Questionnaire for Adolescents (IMQ-A).

Bischof-Kastner, Christina; Kuntsche, Emmanuel; Wolstein, Jörg

2014-10-09

Internationally, up to 15.1% of intensive Internet use among adolescents is dysfunctional. To provide a basis for early intervention and preventive measures, understanding the motives behind intensive Internet use is important. This study aims to develop a questionnaire, the Internet Motive Questionnaire for Adolescents (IMQ-A), as a theory-based measurement for identifying the underlying motives for high-risk Internet use. More precisely, the aim was to confirm the 4-factor structure (ie, social, enhancement, coping, and conformity motives) as well as its construct and concurrent validity. Another aim was to identify the motivational differences between high-risk and low-risk Internet users. A sample of 101 German adolescents (female: 52.5%, 53/101; age: mean 15.9, SD 1.3 years) was recruited. High-risk users (n=47) and low-risk users (n=54) were identified based on a screening measure for online addiction behavior in children and adolescents (Online-Suchtverhalten-Skala, OSVK-S). Here, "high-risk" Internet use means use that exceeds the level of intensive Internet use (OSVK-S sum score ≥7). The confirmatory factor analysis confirmed the IMQ-A's 4-factor structure. A reliability analysis revealed good internal consistencies of the subscales (.71 up to .86). Moreover, regression analyses confirmed that the enhancement and coping motive groups significantly predicted high-risk Internet consumption and the OSVK-S sum score. A mixed-model ANOVA confirmed that adolescents mainly access the Internet for social motives, followed by enhancement and coping motives, and that high-risk users access the Internet more frequently for coping and enhancement motives than low-risk users. Low-risk users were primarily motivated socially. The IMQ-A enables the assessment of motives related to adolescent Internet use and thus the identification of populations at risk. The questionnaire enables the development of preventive measures or early intervention programs, especially dealing

This report explains the relationship between the practice of Internet censorship imposed by the Chinese government and the freedom of its citizens (in the internet surfing experience as the realization of human rights in the freedom of expression and opinion (seek, receive-use, and communicate information which is traced through the relevant literature study. China is a unique case since the internet censorship regulation contributes to its status as the country with the least internet freedom yet at the same time it is credited as having the most internet users globally. In addition, China known as the communist country that began opening up to globalization and information of technology, but the government’s control over it is still so tight and binding, not only in the press, or the traditional media, but also in new media with the internet censorship. The control over this information may have a clear objective to maintain a climate of information in the community, but on the other hand, such control is tantamount to restricting the right of citizens to make, use, and distribute information, and more fatal as a violation of human rights.

The Internet is fast gaining recognition as a powerful, low-cost method to deliver health intervention and prevention programs to large numbers of young people across diverse geographic regions. The feasibility and accessibility of Internet-based health interventions in resource-limited settings, where cost-effective interventions are most needed, is unknown. To determine the utility of developing technology-based interventions in resource-limited settings, availability and patterns of usage of the Internet first need to be assessed. The Uganda Media and You Survey was a cross-sectional survey of Internet use among adolescents (ages 12-18 years) in Mbarara, Uganda, a municipality mainly serving a rural population in sub-Saharan Africa. Participants were randomly selected among eligible students attending one of five participating secondary day and boarding schools in Mbarara, Uganda. Of a total of 538 students selected, 93% (500) participated. Of the total respondents, 45% (223) reported ever having used the Internet, 78% (175) of whom reported going online in the previous week. As maternal education increased, so too did the odds of adolescent Internet use. Almost two in five respondents (38% [189]) reported already having used a computer or the Internet to search for health information. Over one-third (35% [173]) had used the computer or Internet to find information about HIV/AIDS, and 20% (102) had looked for sexual health information. Among Internet users, searching for HIV/AIDS information on a computer or online was significantly related to using the Internet weekly, emailing, visiting chat rooms, and playing online games. In contrast, going online at school was inversely related to looking for HIV/AIDS information via technology. If Internet access were free, 66% (330) reported that they would search for information about HIV/AIDS prevention online. Both the desire to use, and the actual use of, the Internet to seek sexual health and HIV/AIDS information is

Full Text Available With the introduction of new technologies, computer and internet use have become an unavoidable necessity in our daily lives. Internet was originally designed to facilitate communication and research. However the dramatic increase in use of internet in recent years has led to its pathologic use. Turkey, as a developing country with an increasing rate of internet access and computer use is at high risk for this disorder. In our country, this disorder is especially seen in young people who are more skilled in internet and computer use. And because their excessive internet use has led to negative consequences in their academic, social and family lives, patients and their families began search of treatment for this disorder.

Science.gov (United States)

Laplante-Lévesque, Ariane; Thorén, Elisabet Sundewall

2015-09-01

This systematic literature review asks the following question: “ What is the readability of Internet information on hearing that people with hearing impairment and their significant others can access in the context of their hearing care?” Searches were completed in three databases: CINAHL, PubMed, and Scopus. Seventy-eight records were identified and systematically screened for eligibility: 8 records were included that contained data on the readability of Internet information on hearing that people with hear ing impairment and their significant others can access in the context of their hearing care. Records reported mean readability levels from 9 to over 14. In other words, people with hearing impairment and their significant others need 9 to 14 years of education to read and understand Internet information on hearing that they access in the context of their hearing care. The poor readability of Internet information on hearing has been well documented; it is time to focus on valid and sustainable initiatives that address this problem.

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.

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.

Accessing Suicide-Related Information on the Internet: A Retrospective Observational Study of Search Behavior

Science.gov (United States)

2013-01-01

Background The Internet’s potential impact on suicide is of major public health interest as easy online access to pro-suicide information or specific suicide methods may increase suicide risk among vulnerable Internet users. Little is known, however, about users’ actual searching and browsing behaviors of online suicide-related information. Objective To investigate what webpages people actually clicked on after searching with suicide-related queries on a search engine and to examine what queries people used to get access to pro-suicide websites. Methods A retrospective observational study was done. We used a web search dataset released by America Online (AOL). The dataset was randomly sampled from all AOL subscribers’ web queries between March and May 2006 and generated by 657,000 service subscribers. Results We found 5526 search queries (0.026%, 5526/21,000,000) that included the keyword "suicide". The 5526 search queries included 1586 different search terms and were generated by 1625 unique subscribers (0.25%, 1625/657,000). Of these queries, 61.38% (3392/5526) were followed by users clicking on a search result. Of these 3392 queries, 1344 (39.62%) webpages were clicked on by 930 unique users but only 1314 of those webpages were accessible during the study period. Each clicked-through webpage was classified into 11 categories. The categories of the most visited webpages were: entertainment (30.13%; 396/1314), scientific information (18.31%; 240/1314), and community resources (14.53%; 191/1314). Among the 1314 accessed webpages, we could identify only two pro-suicide websites. We found that the search terms used to access these sites included “commiting suicide with a gas oven”, “hairless goat”, “pictures of murder by strangulation”, and “photo of a severe burn”. A limitation of our study is that the database may be dated and confined to mainly English webpages. Conclusions Searching or browsing suicide-related or pro-suicide webpages was

Wegmann, Elisa; Oberst, Ursula; Stodt, Benjamin; Brand, Matthias

2017-06-01

Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with friends all over the world. However, a growing number of users suffer from negative consequences due to their excessive use of these applications, which can be referred to as Internet-communication disorder. The frequent use and easy access of these applications may also trigger the individual's fear of missing out on content when not accessing these applications. Using a sample of 270 participants, a structural equation model was analyzed to investigate the role of psychopathological symptoms and the fear of missing out on expectancies towards Internet-communication applications in the development of symptoms of an Internet-communication disorder. The results suggest that psychopathological symptoms predict higher fear of missing out on the individual's Internet-communication applications and higher expectancies to use these applications as a helpful tool to escape from negative feelings. These specific cognitions mediate the effect of psychopathological symptoms on Internet-communication disorder. Our results are in line with the theoretical model by Brand et al. (2016) as they show how Internet-related cognitive bias mediates the relationship between a person's core characteristics (e.g., psychopathological symptoms) and Internet-communication disorder. However, further studies should investigate the role of the fear of missing out as a specific predisposition, as well as specific cognition in the online context.

Lee, Eun-Ju; Lee, Lu; Jang, Jeongwoo

2011-01-01

Drawing upon the uses and gratifications approach, the current study examined how international students' Internet use motivations affect their academic, social, and emotional adjustments in the new environment. A total of 166 Chinese students studying in Korea participated in a web-based survey. First, a factor analysis identified four distinct motivations for Internet use: homeland orientation (to stay connected to the home country), local information seeking (to learn about the host society), local social interaction (to form interpersonal relationships locally), and entertainment. After controlling for the effects of sociodemographic variables (i.e., gender, year at school, length of residence, Korean language proficiency) and personality traits (i.e., extraversion, openness to experience, neuroticism), Internet use motivations were found to be significant predictors of international students' social and emotional adjustments. Specifically, those seeking to build a local social network through the Internet reported greater satisfaction with their social life, whereas homeland orientation was associated with poorer emotional adaptation. Various Internet activities, such as e-mail, blogging, and instant messaging, were not significantly related to college adjustments, suggesting the multi-functionality of Internet-based communication channels.

As we get into the Internet of Things era, security and privacy concerns remain as the main obstacles in the development of innovative and valuable services to be exploited by society. Given the Machine-to-Machine (M2M) nature of these emerging scenarios, the application of current privacy-friendly technologies needs to be reconsidered and adapted to be deployed in such global ecosystem. This work proposes different privacy-preserving mechanisms through the application of anonymous credential systems and certificateless public key cryptography. The resulting alternatives are intended to enable an anonymous and accountable access control approach to be deployed on large-scale scenarios, such as Smart Cities. Furthermore, the proposed mechanisms have been deployed on constrained devices, in order to assess their suitability for a secure and privacy-preserving M2M-enabled Internet of Things. PMID:26140349

Niedermayer, Heiko; Holz, Ralph; Pahl, Marc-Oliver; Carle, Georg

In this position paper we state four requirements for a Future Internet and sketch our initial concept. The requirements: (1) more comfort, (2) integration of home networks, (3) resources like service clouds in the network, and (4) access anywhere on any machine. Future Internet needs future quality and future comfort. There need to be new possiblities for everyone. Our focus is on higher layers and related to the many overlay proposals. We consider them to run on top of a basic Future Internet core. A new user experience means to include all user devices. Home networks and services should be a fundamental part of the Future Internet. Home networks extend access and allow interaction with the environment. Cloud Computing can provide reliable resources beyond local boundaries. For access anywhere, we also need secure storage for data and profiles in the network, in particular for access with non-personal devices (Internet terminal, ticket machine, ...).

Remote monitoring of instrumented structures using the Internet information superhighway

Science.gov (United States)

Fuhr, Peter L.; Huston, Dryver R.; Ambrose, Timothy P.

1994-09-01

The requirements of sensor monitoring associated with instrumented civil structures poses potential logistical constraints on manpower, training, and costs. The need for frequent or even continuous data monitoring places potentially severe constraints on overall system performance given real-world factors such as available manpower, geographic separation of the instrumented structures, and data archiving as well as the training and cost issues. While the pool of available low wage, moderate skill workers available to the authors is sizable (undergraduate engineering students), the level of performance of such workers is quite variable leading to data acquisition integrity and continuity issues - matters that are not acceptable in the practical field implementation of such developed systems. In the case of acquiring data from the numerous sensors within the civil structures which the authors have instrumented (e.g., a multistory building, roadway/railway bridges, and a hydroelectric dam), we have found that many of these concerns may be alleviated through the use of an automated data acquisition system which archives the acquired information in an electronic location remotely accessible through the Internet global computer network. It is therefore a possible for the data monitoring to be performed at a remote location with the only requirements for data acquisition being Internet accessibility. A description of the developed scheme is presented as well as guiding philosophies.

Development of a secure and cost-effective infrastructure for the access of arbitrary web-based image distribution systems

International Nuclear Information System (INIS)

Hacklaender, T.; Demabre, N.; Cramer, B.M.; Kleber, K.; Schneider, H.

2004-01-01

Purpose: To build an infrastructure that enables radiologists on-call and external users a teleradiological access to the HTML-based image distribution system inside the hospital via internet. In addition, no investment costs should arise on the user side and the image data should be sent renamed using cryptographic techniques. Materials and Methods: A pure HTML-based system manages the image distribution inside the hospital, with an open source project extending this system through a secure gateway outside the firewall of the hospital. The gateway handles the communication between the external users and the HTML server within the network of the hospital. A second firewall is installed between the gateway and the external users and builds up a virtual private network (VPN). A connection between the gateway and the external user is only acknowledged if the computers involved authenticate each other via certificates and the external users authenticate via a multi-stage password system. All data are transferred encrypted. External users get only access to images that have been renamed to a pseudonym by means of automated processing before. Results: With an ADSL internet access, external users achieve an image load frequency of 0.4 CT images per second. More than 90% of the delay during image transfer results from security checks within the firewalls. Data passing the gateway induce no measurable delay. (orig.)

Full Text Available The Internet, which has truly united the developed and developing nations, is an extensive network of inter-linked computers storing immense bytes of information, which can be accessed by anyone transcending all geographi-cal barriers and this has become the ultimate frontier to access information. The Urology and Andrology informa-tion on Internet is exponentially growing. The urologist need not know the intricacies of the hardware and soft-ware but can start right away navigating through this web. We reviewed methods available to take advantage of this network to provide a glimpse to busy urologists to accrue the benefits easily and efficiently rather than to be lost in the information-ocean by surfing individually. By getting connected to Internet, an urologist of any part of the world gains enormous information by interacting with other urologists of the rest of the world. This could be of use to gain knowledge and to offer the best and the most modern treatment to the patient. Internet has revolutionised the scientific publication by virtue of its faster and accurate transmission of manuscripts. We can send manuscripts by this channel and also access journals obviating the lag period inherent in snail mail. The on-line journals have virtually brought the library to the desktop.

Full Text Available Abstract Background The internet is an increasingly important tool for physicians, but the extent to which it is used by dermatologists is unknown. We aimed to investigate the utilization of the internet by dermatologists in Saudi Arabia for medical purposes during their daily practice and to clarify the reasons for its use and non-use. Methods A self-administered questionnaire was distributed to all 160 dermatologists attending the National Dermatology conference in 2007. Results A total of 107 questionnaires were completed. Sixty-two percent of respondents had access to the internet in the workplace. The use of the internet to update medical knowledge was reported by 91%. Only 27% had internet access in consultation rooms. The majority of information retrieval occurred outside patient consultation hours (91%. Only 13% reported using the internet during patient consultation. Possible reasons included: lack of access (54%, time pressure (37%, possible interference with the physician-patient relationship (30%, and that use of the internet was too time-consuming (10%. The mean searching time used to solve a clinical problem was 34 ± 3 minutes. Fifty-eight percent used Pubmed; however, 77% of the dermatologists had no training at all in how to use this tool. Conclusion Professional medical use of the internet is widespread among dermatologists in Saudi Arabia. Providing access to the internet in the workplace and training of dermatologists to perform effective electronic searches are badly needed to improve the professional medical use of internet, which is expected to lead to better delivery of patient care.

Among Internet users, searching for HIV/AIDS information on a computer or online was significantly related to using the Internet weekly, emailing, visiting chat rooms, and playing online games. In contrast, going online at school was inversely related to looking for HIV/AIDS information via technology. If Internet access were free, 66% (330) reported that they would search for information about HIV/AIDS prevention online. Conclusions Both the desire to use, and the actual use of, the Internet to

The authors investigated use of the internet-based patient portal, kp.org, among a well-characterized population of adults with diabetes in Northern California. Among 14,102 diverse patients, 5671 (40%) requested a password for the patient portal. Of these, 4311 (76%) activated their accounts, and 3922 (69%), logged on to the patient portal one or more times; 2990 (53%) participants viewed laboratory results, 2132 (38%) requested medication refills, 2093 (37%) sent email messages, and 835 (15%) made medical appointments. After adjustment for age, gender, race/ethnicity, immigration status, educational attainment, and employment status, compared to non-Hispanic Caucasians, African-Americans and Latinos had higher odds of never logging on (OR 2.6 (2.3 to 2.9); OR 2.3 (1.9 to 2.6)), as did those without an educational degree (OR compared to college graduates, 2.3 (1.9 to 2.7)). Those most at risk for poor diabetes outcomes may fall further behind as health systems increasingly rely on the internet and limit current modes of access and communication.

Full Text Available This study explored the usage of internet for study enrichment and pleasure. Understanding online media audience was becoming increasingly important in Social and Political Faculty, because internet access was one of the academic source used by the student. Most of students did not have sufficient knowledge for self information filtering to provide realible materials from internet and various online sources that fulfilled the academic and scientific requirement. Small number of student explored some opportunities for getting academic  sources through internet, but unfortunately most of them did not have througly understanding to difer valid and reliable information for completing their academic tasks and research.

Search strategies on the Internet: general and specific.

Science.gov (United States)

Bottrill, Krys

2004-06-01

Some of the most up-to-date information on scientific activity is to be found on the Internet; for example, on the websites of academic and other research institutions and in databases of currently funded research studies provided on the websites of funding bodies. Such information can be valuable in suggesting new approaches and techniques that could be applicable in a Three Rs context. However, the Internet is a chaotic medium, not subject to the meticulous classification and organisation of classical information resources. At the same time, Internet search engines do not match the sophistication of search systems used by database hosts. Also, although some offer relatively advanced features, user awareness of these tends to be low. Furthermore, much of the information on the Internet is not accessible to conventional search engines, giving rise to the concept of the "Invisible Web". General strategies and techniques for Internet searching are presented, together with a comparative survey of selected search engines. The question of how the Invisible Web can be accessed is discussed, as well as how to keep up-to-date with Internet content and improve searching skills.

Recently published articles have established that a substantial number of cancer patients utilize the Internet to gather information about their respective diagnoses. The challenges for medical providers include understanding the prevalence and characteristics of patients using the Internet, reasons for Internet use, and the effectiveness of currently available websites in providing useful health-related information to patients. Adults with cancer were asked to complete a self-administered, anonymous, 21-item questionnaire upon registration at the Alvin J. Siteman Cancer Center at the Washington University School of Medicine. There were 500 respondents (mean age 58 years (range 18-90), 83% Caucasian and 15% African-American). Three hundred ninety-eight participants (80%) reported access to the Internet, and 315 (63%) reported searching for information about cancer on the Internet. Patients accessing the Internet for cancer information were younger than those who did not (median age 56 vs. 63 years; p Internet usage for cancer information also differed by race (p Internet for cancer information, 13.3% of patients had their decisions towards treatments affected or changed, and 11.4% of patients had their choice in physicians affected or changed because of Internet use; 23.5% of patients sought information on clinical trials, and 9.5% of patients were influenced or changed their decision regarding clinical trial enrollment due to Internet information. Approximately two thirds of patients with cancer used the Internet to obtain information about their disease. Factors affecting Internet use for cancer information included age, race, and education. Clinical decisions can be affected by Internet use.

Open Access to Multi-Domain Collaborative Analysis of Geospatial Data Through the Internet

Science.gov (United States)

Turner, A.

2009-12-01

The internet has provided us with a high bandwidth, low latency, globally connected network in which to rapidly share realtime data from sensors, reports, and imagery. In addition, the availability of this data is even easier to obtain, consume and analyze. Another aspect of the internet has been the increased approachability of complex systems through lightweight interfaces - with additional complex services able to provide more advanced connections into data services. These analyses and discussions have primarily been siloed within single domains, or kept out of the reach of amateur scientists and interested citizens. However, through more open access to analytical tools and data, experts can collaborate with citizens to gather information, provide interfaces for experimenting and querying results, and help make improved insights and feedback for further investigation. For example, farmers in Uganda are able to use their mobile phones to query, analyze, and be alerted to banana crop disease based on agriculture and climatological data. In the U.S., local groups use online social media sharing sites to gather data on storm-water runoff and stream siltation in order to alert wardens and environmental agencies. This talk will present various web-based geospatial visualization and analysis techniques and tools such as Google Earth and GeoCommons that have emerged that provide for a collaboration between experts of various domains as well as between experts, government, and citizen scientists. Through increased communication and the sharing of data and tools, it is possible to gain broad insight and development of joint, working solutions to a variety of difficult scientific and policy related questions.

Ultra-broadband photonic internet

Science.gov (United States)

Romaniuk, Ryszard S.

2011-06-01

In this paper, there is presented a review of our today's understanding of the ultimately broadband photonic Internet. A simple calculation is presented showing the estimate of the throughput of the core photonic network branches. Optoelectronic components, circuits, systems and signals, together with analogous electronic entities and common software layers, are building blocks of the contemporary Internet. Participation of photonics in development of the physical layer in the future Internet will probably increase. The photonics leads now to a better usage of the available bandwidth (increase of the spectral efficiency measured in Bit/s/Hz), increase in the transmission rate (from Gbps, via Tbps up to probably Pbps), increase in the transmission distance without signal regeneration (in distortion compensated active optical cables), increase in energy/power efficiency measured in W/Gbps, etc. Photonics may lead, in the future, to fully transparent optical networks and, thus, to essential increase in bandwidth and network reliability. It is expected that photonics (with biochemistry, electronics and mechatronics) may build psychological and physiological interface for humans to the future global network. The following optical signal multiplexing methods were considered, which are possible without O/E/O conversion: TDM-OTDM, FDM-CO-OFDM, OCDM-OCDMA, WDM-DWDM.

To identify how nurses use the Internet through a survey performed in May 2005. A descriptive cross-sectional study was performed. The information source was a survey sent electronically and through surface mail. The study population consisted of nursing professionals from distinct autonomous regions. The overall response rate was 40% (444 of 1,100). A total of 38.6% (184) of the nursing professionals used the Internet continually, especially men and nursing staff with a high level of English. The 5 most frequent reasons for surfing the net were searching for nursing literature (63% [264]), consulting the web pages of nursing journals (58.6% [256]), seeking information on drugs (55% [230]), seeking protocol manuals (50% [204]), and consulting the web pages of colleges of nursing (48). The behavior of nursing professionals is similar to that found among the general population in the "BBVA Foundation study of the Internet in Spain". Most nursing professionals are women. Male nursing professionals more frequently search for subjects related to nursing theory. Nurses use the Internet to search for nursing literature and consult journals, protocol manuals, and colleges of nursing, as well as to be familiar with the information aimed at patients.

The Internet's effect on personality traits: An important casualty of the "Internet addiction" paradigm.

Science.gov (United States)

Aboujaoude, Elias

2017-03-01

Background and aims The "Internet addiction" paradigm has been criticized for several shortcomings, including inattention to specific online behaviors, not distinguishing the Internet from other media, insufficient focus on comorbidities, and definitions that do not take into account the constant access now possible. The paradigm's biggest casualty, however, may be that it has diverted attention away from subtle personality changes that seem to occur online, including in users who cannot be considered "addicted" under any definition. Methods A narrative assessment of the literature was conducted, focusing on the Internet's effects on personality traits as revealed in studies of Internet users. Results Impulsivity, narcissism, and aggression are some of the personality traits that seem to be nurtured by the Internet, with possible negative offline consequences. Discussion Ignoring the Internet's subtle effects on personality as we embrace an addiction model that implies severe pathology makes the majority of Internet users feel deceptively immune to the psychological effects of new technologies. It also limits our understanding of the big cultural shifts that are happening as a result. Conclusion The Internet's potentially negative effect on personality, and by extension on society at large, is a fundamental part of online psychology, one well worthy of further investigation.

Christakis Dimitri A

2010-10-01

Full Text Available Abstract Internet addiction, while not yet officially codified within a psychopathological framework, is growing both in prevalence and within the public consciousness as a potentially problematic condition with many parallels to existing recognized disorders. The rapid and unfettered increase in the number of people accessing a relatively unrestricted internet substantially increases the possibility that those suffering with an underlying psychological comorbidity may be at serious risk of developing an addiction to the internet, lending further credence to this hitherto understudied condition. In this commentary, I outline my recommendations for improved diagnosis, study and prevention of internet addiction.

The emergence of internet-based virtual private networks in international safeguards

International Nuclear Information System (INIS)

Smartt, Heidi Anne

2001-01-01

Full text: The costs associated with secure data transmission can be an obstacle to International Safeguards. Typical communication methods are priced by distance and may include telephone lines, frame relay, and ISDN. It is therefore costly to communicate globally. The growth of the Internet has provided an extensive backbone for global communications; however, the Internet does not provide intrinsic security measures. Combining the Internet with Virtual Private Network technology, which encrypts and authenticates data, creates a secure and potentially cost-effective data transmission path, as well as achieving other benefits such as reliability and scalability. Access to the Internet can be achieved by connecting to a local Internet Service Provider, which can be preferable to installing a static link between two distant points. The cost-effectiveness of the Internet-based Virtual Private Network is dependent on such factors as data amount, current operational costs, and the specifics of the Internet connection, such as user proximity to an Internet Service Provider or existing access to the Internet. This paper will introduce Virtual Private Network technology, the benefits of Internet communication, and the emergence of Internet-based Virtual Private Networks throughout the International Safeguards community. Specific projects to be discussed include: The completed demonstration of secure remote monitoring data transfer via the Internet between STUK in Helsinki, Finland, and the IAEA in Vienna, Austria; The demonstration of secure remote access to IAEA resources by traveling inspectors with Virtual Private Network software loaded on laptops; The proposed Action Sheets between ABACC/DOE and ARN/DOE, which will provide a link between Rio de Janeiro and Buenos Aires; The proposed use at the HIFAR research reactor, located in Australia, to provide remote monitoring data to the IAEA; The use of Virtual Private Networks by JRC, Ispra, Italy.

Full Text Available Use of the internet may provide tools and resources for better decision making, yet little is known about the association of internet use with decision-making in older persons. We examined this relationship in 66190 community-dwelling older persons without dementia from the Rush Memory and Aging Project, an ongoing longitudinal study of aging. Participants were asked to report if they had access to the internet and how frequently they used the internet and email. A 12-item instrument was used to assess financial and healthcare decision making using materials designed to approximate those used in real world settings. Items were summed to yield a total decision-making score. Associations were tested via linear regression models adjusted for age, sex, race, education, and a measure of global cognitive function. Secondary models further adjusted for income, depression, loneliness, social networks, social support, chronic medical conditions, instrumental activities of daily living, life space size, and health and financial literacy. Interaction terms were used to test for effect modification. Almost 70% of participants had access to the internet, and of those with access, 55% used the internet at least several times a week. Higher frequency of internet use was associated with better financial and healthcare decision making (β=0.11, p=0.002. The association persisted in a fully adjusted model (β=0.08, p=0.024. Interaction models indicated that higher frequency of internet use attenuated the relationships of older age, poorer cognitive function, and lower levels of health and financial literacy with poorer healthcare and financial decision making. These findings indicate that internet use is associated with better health and financial decision making in older persons. Future research is required to understand whether promoting the use of the internet can produce improvements in healthcare and financial decision making.

Uncertainty around the value of and appropriate regulatory models for direct-to-consumer (DTC) genetic testing underscores the importance of tracking public awareness of these services. We analyzed nationally representative, cross-sectional data from the Health Information National Trends Survey in 2008 (n = 7, 674) and 2011 (n = 3, 959) to assess population-level changes in awareness of DTC genetic testing in the U.S. and to explore sociodemographic, health care, Internet use, and population density correlates. Overall, awareness increased significantly from 29% in 2008 to 37% in 2011. The observed increase in awareness from 2008 to 2011 remained significant (OR = 1.39) even when adjusted for sociodemographic variables, health care access, Internet use, and population density. Independent of survey year, the odds of awareness of DTC genetic tests were significantly higher for those aged 50-64 (OR = 1.64), and 65-74 (OR = 1.60); college graduates (OR = 2.02); those with a regular source of health care (OR = 1.27); those with a prior cancer diagnosis (OR = 1.24); those who use the Internet (OR = 1.27); and those living in urban areas (OR = 1.25). Surveillance of awareness-along with empirical data on use of and response to genetic risk information-can inform public health and policy efforts to maximize benefits and minimize risks of DTC genetic testing.

Internet firewalls: questions and answers

Science.gov (United States)

Ker, Keith

1996-03-01

As organizations consider connecting to the Internet, the issue of internetwork security becomes more important. There are many tools and components that can be used to secure a network, one of which is a firewall. Modern firewalls offer highly flexible private network security by controlling and monitoring all communications passing into or out of the private network. Specifically designed for security, firewalls become the private network's single point of attack from Internet intruders. Application gateways (or proxies) that have been written to be secure against even the most persistent attacks ensure that only authorized users and services access the private network. One-time passwords prevent intruders from `sniffing' and replaying the usernames and passwords of authorized users to gain access to the private network. Comprehensive logging permits constant and uniform system monitoring. `Address spoofing' attacks are prevented. The private network may use registered or unregistered IP addresses behind the firewall. Firewall-to-firewall encryption establishes a `virtual private network' across the Internet, preventing intruders from eavesdropping on private communications, eliminating the need for costly dedicated lines.

The Role and Implications of the Internet in Healthcare Delivery

Science.gov (United States)

Broom, Alex

Drawing on a study of the Internet usage of Australian men with prostate cancer, this chapter investigates how access to information and online support affects men’s experiences of disease and, in particular, the possible implications of Internet-informed patients for the doctor/patient relationship. The data reveal that accessing information and/or support online can have a profound effect on men’s experiences of prostate cancer, providing a method of taking some control over their disease and limiting inhibitions experienced in face-to-face encounters. However, it is also clear that some medical specialists view Internet-informed patients as a challenge to their power within medical encounters and, as a result, employ disciplinary strategies that reinforce traditional patient roles and alienate patients who use the Internet.

[Readability and internet accessibility of informative documents for spinal cord injury patients in Spanish].

Patients with spinal cord injuries and their carers have access to leaflets on Internet that they can use as educational material to complement traditional forms of education. The aim of this study is to evaluate the readability of informative documents in Spanish, obtained from Internet and aimed at patients with spinal cord injuries. A search was made with the Google search engine using the following key words: recommendation, advice, guide, manual, self-care, education and information, adding spinal cord injury, paraplegia and tetraplegia to each of the terms. We analyzed the first 50 results of each search. The readability of the leaflets was studied with the Flesch-Szigriszt index and the INFLESZ scale, both available on the INFLESZ program. Also indicated were year of publication, country and number of authors of the documents obtained. We obtained 16 documents, developed between 2001 and 2011. Readability oscillated between 43.34 (some-what difficult) and 62 (normal), with an average value of 51.56 (somewhat difficult). Only 4 pamphlets (25%) showed a Flesch-Szigriszt index of ≥ 55 (normal). There was no difference in readability by year, authors or country of publication. The readability of 75% of the documents studied was "somewhat difficult" according to the INFLESZ scale. These results coincide with previous studies, in both Spanish and English. If the readability of this type of documents is improved, it will be easier to achieve their educational goal.

Alcoholics Anonymous is not yet fully employed by the medical community as a means to enhance patient outcome. The purpose of this study was to evaluate visitors' use of an Internet course on Alcoholics Anonymous, and to compare how various disciplines learned about, gained access to and participated in the course. Demographic information was collected from 414 visitors to the course. 64% of the 414 respondents received their last educational degree within the last 10 years, and had an interest in the topic of addiction prior to their accessing the site. 294 (71%) of those who accessed the course completed it, and those who accessed it learned about it from various sources other than print advertisement in professional journals. Within the 230 physician respondents, 143 (62%) were psychiatrists, 82 (78%) of whom learned about the Internet course via professional journal. Given the need for further training among physicians in the use of Alcoholics Anonymous, the Internet can be utilized to make information available to a large number of people. Because it allows the user to access information outside the traditional means, the barriers to its use are minimal, and it has the potential to effectively convey useful clinical information.

The twinning of Scottish general practices and Malawian clinics: the provision of email and internet services

Full Text Available Many patients and health care professionals in the developed world are uncomfortable about doing nothing in the face of the glaring inequities in health care between their own environment and that of Africa. In an effort to 'think global, act local' a Scottish GP practice used personal contacts to build a twinning link with a clinic serving a township in Malawi. This article describes the experience of establishing e-mail and internet services for Malawian health care staff to afford them the same level of access as developed world staff enjoy in accessing educational materials and professional supports. Using our twin link as an exemplar we are now matching other Scottish General Practices to Malawian Clinics around a common theme of modern communication media.

The Internet hospital, an innovative approach to providing health care, is rapidly developing in China because it has the potential to provide widely accessible outpatient service delivery via Internet technologies. To date, China's Internet hospitals have not been systematically investigated. The aim of this study was to describe the characteristics of China's Internet hospitals, and to assess their health service capacity. We searched Baidu, the popular Chinese search engine, to identify Internet hospitals, using search terms such as "Internet hospital," "web hospital," or "cloud hospital." All Internet hospitals in mainland China were eligible for inclusion if they were officially registered. Our search was carried out until March 31, 2017. We identified 68 Internet hospitals, of which 43 have been put into use and 25 were under construction. Of the 43 established Internet hospitals, 13 (30%) were in the hospital informatization stage, 24 (56%) were in the Web ward stage, and 6 (14%) were in full Internet hospital stage. Patients accessed outpatient service delivery via website (74%, 32/43), app (42%, 18/43), or offline medical consultation facility (37%, 16/43) from the Internet hospital. Furthermore, 25 (58%) of the Internet hospitals asked doctors to deliver health services at a specific Web clinic, whereas 18 (42%) did not. The consulting methods included video chat (60%, 26/43), telephone (19%, 8/43), and graphic message (28%, 12/43); 13 (30%) Internet hospitals cannot be consulted online any more. Only 6 Internet hospitals were included in the coverage of health insurance. The median number of doctors available online was zero (interquartile range [IQR] 0 to 5; max 16,492). The median consultation fee per time was ¥20 (approximately US $2.90, IQR ¥0 to ¥200). Internet hospitals provide convenient outpatient service delivery. However, many of the Internet hospitals are not yet mature and are faced with various issues such as online doctor scarcity and

2002-01-01

The NASA Glenn Research Center successfully demonstrated a transmission-control-protocol/ Internet-protocol- (TCP/IP) based approach to the command and control of onorbit assets over a secure network. This is a significant accomplishment because future NASA missions will benefit by using Internet-standards-based protocols. Benefits of this Internet-based space command and control system architecture include reduced mission costs and increased mission efficiency. The demonstration proved that this communications architecture is viable for future NASA missions. This demonstration was a significant feat involving multiple NASA organizations and industry. Phillip Paulsen, from Glenn's Project Development and Integration Office, served as the overall project lead, and David Foltz, from Glenn's Satellite Networks and Architectures Branch, provided the hybrid networking support for the required Internet connections. The goal was to build a network that would emulate a connection between a space experiment on the International Space Station and a researcher accessing the experiment from anywhere on the Internet, as shown. The experiment was interfaced to a wireless 802.11 network inside the demonstration area. The wireless link provided connectivity to the Tracking and Data Relay Satellite System (TDRSS) Internet Link Terminal (TILT) satellite uplink terminal located 300 ft away in a parking lot on top of a panel van. TILT provided a crucial link in this demonstration. Leslie Ambrose, NASA Goddard Space Flight Center, provided the TILT/TDRSS support. The TILT unit transmitted the signal to TDRS 6 and was received at the White Sands Second TDRSS Ground Station. This station provided the gateway to the Internet. Coordination also took place at the White Sands station to install a Veridian Firewall and automated security incident measurement (ASIM) system to the Second TDRSS Ground Station Internet gateway. The firewall provides a trusted network for the simulated space

approaches. The cost to implement is much less than current approaches due to the availability of highly reliable and standard Internet tools. Use of standard Internet applications onboard reduces the risk of obsolescence inherent in custom protocols due to extremely wide use across all domains. These basic building blocks provide the framework for building onboard software to support direct user communication with payloads including payload control. Other benefits are payload to payload communication from dissimilar spacecraft, constellations of spacecraft, and reconfigurability on orbit. This work is funded through contract with the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC).

The rapid development of the Internet and the increasing interest in Internet-based solutions has promoted the idea of creating Internet-based health information applications. This will force a change in the role of IC cards in healthcare card systems from a data carrier to an access key medium. At the Medical Informatics Department of Kyoto University Hospital we are developing a smart card patient information project where patient databases are accessed via the Internet. Strong end-to-end data encryption is performed via Secure Socket Layers, transparent to transmit patient information. The smart card is playing the crucial role of access key to the database: user authentication is performed internally without ever revealing the actual key. For easy acceptance by healthcare professionals, the user interface is integrated as a plug-in for two familiar Web browsers, Netscape Navigator and MS Internet Explorer.

With this issue, the Journal begins to create an access to the Internet. Our future on the Internet will be achieved systematically, and it will be designed to compliment--add value to--the print Journal. Our Internet connection must be useful to our readers in ways not possible with the print Journal, however, economic considerations cannot be ignored. It would be intellectually and economically unacceptable to produce only a direct copy of theJournal for electronic distribution. The Internet--the information super highway--has been hailed by many as an important information source in the educational process and will become increasingly so in the future. Indeed, there are extant descriptions of apparently innovative uses of modern interactive communications technologies in the education of scientists at the undergraduate level. However, anyone who has attempted to obtain information from the Internet knows that you are as likely to find garbage as you are to find quality information. Webster tells us that garbage is "worthless or nonsensical matter; rubbish; inferior or offensive material; incorrect, meaningless, or unwanted information." An eye for discrimination, which is often a reflection of maturity, is essential when using the current Internet. In other words, because a bit of information appears on the Internet does not ensure its quality. Only in cases where the information sought has its source in a review-oriented process, e.g., from library holdings, can the information on the Internet be trusted. The Internet is fast becoming a "vanity press," where anything can be published with virtually no critique regarding the quality and accuracy of the content. Indeed, it is not necessarily true that the person to whom a bit of information is attributed is the person who posted it. A bit of information on the Internet lies there until someone comes across it and uses it (or links to it), forming a nucleus for further growth. Further growth may center about

2017-03-31

For persons living with chronic medical conditions, the Internet can be a powerful tool for health promotion, and allow for immediate access to medical information and social support. However, women living with human immunodeficiency virus (HIV) in the United States face numerous barriers to computer and Internet use. Health behavior change models suggest that the first step towards adopting a new health behavior is to improve attitudes towards that behavior. To develop and pilot test Get+Connected, an intervention to improve computer and Internet attitudes and Internet use among women living with HIV. To develop Get+Connected, we reviewed the extant literature, adapted an existing curriculum, and conducted a focus group with HIV-positive women (n=20) at a community-based organization in the Bronx, New York. Get+Connected was comprised of five weekly sessions covering the following topics: basic computer knowledge and skills, identifying reliable health-related websites, setting up and using email and Facebook accounts, and a final review session. We recruited 12 women to participate in pilot testing. At baseline, we collected data about participants' sociodemographic information, clinical characteristics, and technology device ownership and use. At baseline, intervention completion, and three months postintervention, we collected data regarding attitudes towards computers and the Internet (Attitudes Towards Computers and the Internet Questionnaire [ATCIQ]; possible scores range from 5-50) as well as frequency of Internet use (composite measure). To examine changes in ATCIQ scores and Internet use over time, we used generalized estimating equations. We also collected qualitative data during intervention delivery. Among women in our sample, the median age was 56 years (interquartile range=52-63). All participants were black/African American and/or Latina. Seven participants (7/12, 58%) had a high school diploma (or equivalent) or higher degree. Ten participants (10

Using the Internet in the management of asthma.

Science.gov (United States)

Patel, A M

2001-01-01

The ultimate goals of managing asthma are to eliminate death, prevent or promptly treat exacerbations, and maximize the quality of life and health status of patients. Current strategies include appropriate education, trigger control, and timely access to effective pharmacotherapy and follow-up. Internet-based technologies have emerged as potentially powerful tools to enable meaningful communication and proactive partnership in care for various medical conditions. The main types of Internet-based applications for asthma management include remote monitoring and feedback between health professionals and their patients; online education and marketing for either patients or professionals; networking and collaborative research; and administrative oversight through policy making, planning, and decision support. With increased understanding of integrated disease management and the technostructural as well as psychodynamic issues related to Internet use, further refinement and evolution of the Internet and related technologies may drastically improve the way we monitor, educate, treat, and establish policies for this global problem while attending to individual or local community needs. This review presents a conceptual overview of the current challenges and use of the Internet for improving asthma management through timely and tailored education and appropriate access to health care expertise.

Full Text Available Abstract Background Access to medical literature in developing countries is helped by open access publishing and initiatives to allow free access to subscription only journals. The effectiveness of these initiatives in Africa has not been assessed. This study describes awareness, reported use and factors influencing use of on-line medical literature via free access initiatives. Methods Descriptive study in four teaching hospitals in Cameroon, Nigeria, Tanzania and Uganda plus one externally funded research institution in The Gambia. Survey with postgraduate doctors and research scientists to determine Internet access patterns, reported awareness of on-line medical information and free access initiatives; semi structured interviews with a sub-sample of survey participants to explore factors influencing use. Results In the four African teaching hospitals, 70% of the 305 postgraduate doctors reported textbooks as their main source of information; 66% had used the Internet for health information in the last week. In two hospitals, Internet cafés were the main Internet access point. For researchers at the externally-funded research institution, electronic resources were their main source, and almost all had used the Internet in the last week. Across all 333 respondents, 90% had heard of PubMed, 78% of BMJ on line, 49% the Cochrane Library, 47% HINARI, and 19% BioMedCentral. HINARI use correlates with accessing the Internet on computers located in institutions. Qualitative data suggested there are difficulties logging into HINARI and that sometimes it is librarians that limit access to passwords. Conclusion Text books remain an important resource for postgraduate doctors in training. Internet use is common, but awareness of free-access initiatives is limited. HINARI and other initiatives could be more effective with strong institutional endorsement and management to promote and ensure access.

Internet addiction disrupts the daily lives of adolescents. We investigated the prevalence of Internet addiction in junior high school students, elucidated the relation between Internet addiction and mental states, and determined the factors associated with Internet addiction in adolescents. Junior high school students (aged 12-15 years) were assessed using Young's Internet Addiction Test (IAT), the Japanese version of the General Health Questionnaire (GHQ), and a questionnaire on access to electronic devices. Based on total IAT scores, 2.0% (male, 2.1%; female, 1.9%) and 21.7% (male, 19.8%; female, 23.6%) of the total 853 participants (response rate, 97.6%) were classified as addicted and possibly addicted, respectively. Total GHQ scores were significantly higher in the addicted (12.9 ± 7.4) and possibly addicted groups (8.8 ± 6.0) than in the non-addicted group (4.3 ± 4.6; P addicted group than in the non-addicted group. Further, accessibility to smartphones was significantly associated with Internet addiction. Students in the addicted and possibly addicted groups were considered 'problematic' Internet users. Use of smartphones warrants special attention, being among the top factors contributing to Internet addiction. © 2016 The Authors.

RWE NUKEM's 'Living' Nuclear Compendium eNICE. An internet-based, multifunctional nuclear information platform

International Nuclear Information System (INIS)

Kwasny, R.; Max, A.

2002-01-01

Information has become a commodity particularly important to industry, science, and politics. Information becomes critical because of its rapid change. The basis and the catalyst of this change in information are the information technologies now available, and the Internet with its varied contents. This makes the Internet a new market place which, although it is open, can quickly turn into an information maze because of its sheer volume. Also the nuclear industry must find its way through this maze. eNICE was created in order to build a bridge between the flood of information in the Internet and the information really needed in a specific case. eNICE (e stands for electronic, and NICE stands for Nuclear Information Compendium Europe), a living Internet-based nuclear compendium in the English language, is a unique combination of a broad spectrum of information and data about the use of nuclear power in Europe. The information and data contained in eNICE are interconnected with the World Wide Web in such a way that structured searching for nuclear information is possible quickly and efficiently. This avoids the difficulties sometimes encountered in searches in the Internet as a consequence of the unstructured volume of information. A monthly update of eNICE ensures that the data available are up to date and reliable. eNICE also offers direct access to the library used by RWE NUKEM for internal purposes. (orig.) [de

In order to replenish Malaysian economy through tourism, the Malaysian government has to diversify the present tourism products and offers a wide variety of tourism packages. This has mentioned in the National Key Results Area (NKRA development platform highlighted in the 10th Malaysian Plan. Therefore, the tourism sector needs to continuously re-engineer and adapt its business model to suit every customer’s needs and demands, including disabled people. At the moment, one of the highest tourist attraction contributors in Malaysia is the heritage building sector. The heritage building sector in Malaysia becomes popular due to its diverse historical background and culture. It attracts local and international tourists to visit.

The Physical Internet and Business Model Innovation

Full Text Available Building on the analogy of data packets within the Digital Internet, the Physical Internet is a concept that dramatically transforms how physical objects are designed, manufactured, and distributed. This approach is open, efficient, and sustainable beyond traditional proprietary logistical solutions, which are often plagued by inefficiencies. The Physical Internet redefines supply chain configurations, business models, and value-creation patterns. Firms are bound to be less dependent on operational scale and scope trade-offs because they will be in a position to offer novel hybrid products and services that would otherwise destroy value. Finally, logistical chains become flexible and reconfigurable in real time, thus becoming better in tune with firm strategic choices. This article focuses on the potential impact of the Physical Internet on business model innovation, both from the perspectives of Physical-Internet enabled and enabling business models.

Post-migration stressors represent significant obstacle to refugee adjustment, and continued exposure to post-migration stressors can negatively affect mental and physical health. Communities of support maintained over the Internet may provide a sense of constancy and reliability that may insulate against the negative effects of stress. We conducted five focus group interviews with Iraqi and Sudanese refugees to understand how refugees use the Internet to access support in their daily lives. Four trends were observed: (a) Internet use was related to culture of origin, (b) refugees were reluctant to explore online, (c) children served as brokers of online knowledge, and (d) limited Internet access is associated with increased time and financial obligations. This study aims to contribute to theory on Internet-mediated social support and to refugee health by creating smoother pathways to self-sufficiency and allowing refugees to exhibit agency in constructing and maintaining online networks of support. © The Author(s) 2015.

Full Text Available In this article we discuss the ethical use of the internet as a scientific research tool by showing the difference between ethics and moral and between ethics and the common sense doing. For that, the text explores since the internet origins in order to compare the access facility to the scientific texts in the internet versus the access difficulty to the printed versions of scientific texts. It asks, also, if the pressure came from the research centers about the quantity of publications brings an anti-ethics attitude to the scientist. It focuses, specially, on the necessity of constructing a discussion about the ethical posture in the academic environment to make the researcher an original texts writer and not a writer of plagiarized internet texts.

Communicating via Internet and Intranet

Full text: Not so long ago, the simple existence of a company's web site could be seen as a way on its own to promote an image of modernism and openness. Today, the use of internet has become so commonplace and the number of sites related to any given industry so huge that companies must build a specific internet communication strategy should they want to ensure a minimum of efficiency to their 'cyber communication'. This is especially true for the nuclear industry: in its case, the challenge is to provide relevant and dated up information to a broad and demanding audience when at the same time responding to attacks from opponents who master 'cyber-activism' with a great deal of skill. Starting from this background, the proposed contribution will address the following topics: - Maintaining visibility among some 1,000 web sites registered under the name 'nuclear'; - Communicating in real time through internet (and intranet internally); Ensuring synergy between internet and other communication tools.
