    IT Department

    2008-01-01

    The data service on GSM subscriptions has been improved, allowing CERN users to access the Internet directly. A CERN GSM subscription with data option now allows you to connect to the Internet from a mobile phone or a PC equipped with a GSM modem. The previous access (CERN intranet) still exists. To get access to the new service, you will find all the information on configurations at: http://cern.ch/gprs The use of this service on the Sunrise network is charged on a flat-rate basis (no extra charge related to the volume of downloaded data). Depending on your CERN subscription type (standard or master), you can also connect to foreign GSM data networks (roaming), but this is strongly discouraged, except where absolutely necessary, due to international roaming charges.

    2012-08-01

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

    2015-10-01

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

    Full Text Available This review gives an overview of the societal inequalities faced by people with intellectual disabilities, before focusing specifically on challenges people face accessing the Internet. Current access will be outlined along with the societal, support and attitudinal factors that can hinder access. Discussion of carer views of Internet use by people with intellectual disabilities will be covered incorporating consideration of the tension between protection, self-determination and lifestyle issues and gaining Internet access. We will address how impairment related factors may impede access and subsequently discuss how supports may be used to obfuscate impairments and facilitate access. We will move on from this to critically describe some of the potential benefits the Internet could provide to people with intellectual disabilities, including the potential for self-expression, advocacy and developing friendships. Finally, strategies to better include people with intellectual disabilities online will be given along with future research suggestions.

    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.

    Full Text Available The major objective of the study was to examine the accessibility and utilization of Internet service by graduate students in university of Lagos, Nigeria. Specifically, the study made effort to determine the extent to which Internet service was accessible to staff and students of the university, how point of Internet access influenced its usage, factors motivating the use of Internet and what Internet was used for by graduate students in University of Lagos. The study adopted a descriptive survey design and data were collected by administering questionnaires to two hundred respondents randomly selected from faculty of Education in the University. Results of the findings revealed that students didn’t have as much access to Internet service as the staff (27.7 % and 62.4 % respectively. 47.9 % of respondents strongly agreed to visiting the cybercafé to access Internet. 53.1 % and 50.2 % of the respondents strongly agreed that proximity to cybercafé and valid information contained from the Internet were their major motivating factors for surfing the Internet. It also found that the respondents strongly agreed that the purposes for their surfing the Internet were to register courses, enroll for exams, gather information for literature review, send and receive mails, amongst others. Based on the findings, it is therefore recommended that since the Internet is being utilized in every sector such as Education, Banking, Medicine and others, the University should make Internet service assessible for students’ use. This study can further be conducted in other institutions in Nigeria.

    2017-07-01

    The ways in which people learn, remember, and solve problems have all been impacted by the Internet. The present research explored how people become primed to use the Internet as a form of cognitive offloading. In three experiments, we show that using the Internet to retrieve information alters a person's propensity to use the Internet to retrieve other information. Specifically, participants who used Google to answer an initial set of difficult trivia questions were more likely to decide to use Google when answering a new set of relatively easy trivia questions than were participants who answered the initial questions from memory. These results suggest that relying on the Internet to access information makes one more likely to rely on the Internet to access other information.

    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.

    2004-06-01

    Full Text Available This study explores the employees’ concept of appropriate use of Internet facilities as well as their perception of the rights and liabilities, both of the individual and of the organization, associated with the grant of Internet access privileges in the workplace. It further examines how employees perceive their organization’s monitoring of employees online activities and the use of an Internet Usage Policy, whether these are seen as monitoring and control mechanisms or as ways to ensure that Internet access facilities are shared equitably and used responsibly. While the issue of the impact of Internet access on employee productivity will not directly be tackled, the study will provide insights into the frequency and type of usage of Internet facilities in the workplace. Considering the sizeable investment that an organization makes to provide Internet facilities, determining how employees use these facilities to achieve the goals of the organization is, in the very least, interesting and for most organizations concerned with their survival in difficult times, critically important.

    2013-01-01

    A crucial open problem inS large-scale quantum networks is how to efficiently transmit quantum data among many pairs of users via a common data-transmission medium. We propose a solution by developing a quantum code division multiple access (q-CDMA) approach in which quantum information is chaotically encoded to spread its spectral content, and then decoded via chaos synchronization to separate different sender-receiver pairs. In comparison to other existing approaches, such as frequency division multiple access (FDMA), the proposed q-CDMA can greatly increase the information rates per channel used, especially for very noisy quantum channels.

    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.

    2012-01-01

    Despite the amount of health information available online, there are several barriers that limit the Internet from being adopted as a source of health information. The purpose of this study was to identify individual skill-related problems that users experience when accessing the Internet for health information and services. Between November 2009 and February 2010, 88 subjects participated in a performance test in which participants had to complete health-related assignments on the Internet. Subjects were randomly selected from a telephone book. A selective quota sample was used and was divided over equal subsamples of gender, age, and education. Each subject was required to complete nine assignments on the Internet. The general population experiences many Internet skill-related problems, especially those related to information and strategic Internet skills. Aging and lower levels of education seemed to contribute to the amount of operational and formal skill-related problems experienced. Saving files, bookmarking websites, and using search engines were troublesome for these groups of people. With respect to information skills, the higher the level of educational attainment, the less problems the participants experienced. Although younger subjects experienced far less operational and formal skill-related problems, it was revealed that older subjects were less likely to select and use irrelevant search results and unreliable sources. Concerning the strategic Internet skills it was revealed that older subjects were less likely to make inappropriate decisions based on information gathered. The amount of online health-related information and services is consistently growing; however, it appears that the general population experiences many skill-related problems, particularly those related to information and strategic Internet skills, and they become very important when it comes to health. These skills are also problematic for younger generations who are often seen as

    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.

    Full Text Available Network communication and micro-electro-mechanical embedded technologies have attracted much attention in recent years. Through these technologies, the capabilities of sensing, identification, and communication can be embedded in various smart devices. These smart devices can automatically connect to the Internet and form an intelligent network called Internet of Things (IoT. However, these devices are embedded with different wireless communication interfaces such as Wi-Fi and ZigBee. This paper presents the design and implementation of an IoT access point that supports functionalities of coordination of various wireless transmission protocols. Based on the existing Wi-Fi access point, we have embedded a ZigBee module and implemented ZigBee and UPnP protocols into the designed IoT access point, which supports ZigBee communication capabilities over the Internet.

    Internet has become a major tool for patients to search for health-related information and to communicate on health. We currently lack data on how patients with psychiatric disorders access and use Internet to search for information on their mental health. This study aimed to assess, in patients followed for a psychiatric disorder (schizophrenia, bipolar disorder, mood and anxiety disorder, substance-related and addictive disorders and eating disorders), prevalence of Internet access and use, and patient expectations and needs regarding the use of Internet to search for mental-health information depending on the psychiatric disorder. We conducted this cross-sectional study between May 2013 and July 2013 in 648 patients receiving psychiatric care in 8 hospitals from the Region Centre, France. We used multivariate logistic regression adjusted for age, gender, socio-educational level and professional status to compare use, expectations and needs regarding Internet-based information about the patient's psychiatric disorder (65-items self-administered questionnaires) as a function of the psychiatric disorders. We identified patients clusters with multiple correspondence analysis and ascending hierarchical classification. Although 65.6% of our population accessed Internet at home, prevalence for Internet access varied depending on the type of psychiatric disorder and was much more related to limited access to a computer and low income than to a lack of interest in the Internet. Most of the patients who used Internet were interested in having access to reliable Internet-based information on their health (76.8%), and most used Internet to search for Internet based health-information about their psychiatric disorder (58.8%). We found important differences in terms of expectations and needs depending on the patient's psychiatric disorder (e.g., higher interest in Internet-based information among patients with bipolar disorder, substance-related and addictive disorders

    1999-01-01

    At the public environmental impact enquiry for the LHC project, the municipal authorities at Cessy suggested creating a new approach road to the civil engineering site (Point5) to ensure that materials deliveries by road are kept well away from housing along the Route de la Plaine.Following this recommendation, a track called the Chemin du Milieu has been upgraded into a road, and has been made available for the sole use of construction firms involved in building work at Point 5.The 'Dragados-Seli' consortium will be in charge of site surveillance for the new approach road.With effect from 29 March 1999, the present entrance will be closed to civil engineering firms and reserved for LEP installations maintenance services under the SL Division site managers, Mr. R. Spigato (tel. 160374) and P. Rey (tel. 160375).For obvious security reasons, those needing to use Point 5 are requested to keep the gate locked, even while they are on site, so as to prevent unauthorised persons from gaining access to the civil engi...

    This paper explores the advantages and disadvantages of a medical network based on point-to-point communication and a medical network based on Jabber instant messaging protocol. Instant messaging might be, for many people, a convenient way of chatting over the Internet. We will attempt to illustrate how an instant messaging protocol could serve in the best way medical services and provide great flexibility to the involved parts. Additionally, the directory services and presence status offered by the Jabber protocol make it very attractive to medical applications that need to have real time and store and forward communication. Furthermore, doctors connected to Internet via high-speed networks could benefit by saving time due to the data transmission acceleration over Jabber

  8. 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.

    2005-01-01

    Past studies have noted a digital divide, or inequality in computer and Internet access related to socioeconomic class. This study sought to measure how many households in a pediatric primary care outpatient clinic had household access to computers and the Internet, and whether this access differed by socio-economic status or other demographic information. We conducted a phone survey of a population-based sample of parents with children ages 0 to 11 years old. Analyses assessed predictors of having home access to a computer, the Internet, and high-speed Internet service. Overall, 88.9% of all households owned a personal computer, and 81.4% of all households had Internet access. Among households with Internet access, 48.3% had high speed Internet at home. There were statistically significant associations between parental income or education and home computer ownership and Internet access. However, the impact of this difference was lessened by the fact that over 60% of families with annual household income of $10,000–$25,000, and nearly 70% of families with only a high-school education had Internet access at home. While income and education remain significant predictors of household computer and internet access, many patients and families at all economic levels have access, and might benefit from health promotion interventions using these modalities.

    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. 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 enrollment and usage were extracted from the webserver. 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 enroll each patient. Patient Internet access to secondary care records concerning a complex chronic disease is feasible and popular, providing an increased sense of empowerment and understanding, with no

    2018-01-31

    Localization of access points has become an important research problem due to the wide range of applications it addresses such as dismantling critical security threats caused by rogue access points or optimizing wireless coverage of access points within a service area. Existing proposed solutions have mostly relied on theoretical hypotheses or computer simulation to demonstrate the efficiency of their methods. The techniques that rely on estimating the distance using samples of the received signal strength usually assume prior knowledge of the signal propagation characteristics of the indoor environment in hand and tend to take a relatively large number of uniformly distributed random samples. This paper presents an efficient and practical collaborative approach to detect the location of an access point in an indoor environment without any prior knowledge of the environment. The proposed approach comprises a swarm of wirelessly connected mobile robots that collaboratively and autonomously collect a relatively small number of non-uniformly distributed random samples of the access point's received signal strength. These samples are used to efficiently and accurately estimate the location of the access point. The experimental testing verified that the proposed approach can identify the location of the access point in an accurate and efficient manner.

    2010-08-01

    Full Text Available This paper will have two parts. In the first part the author will focus on the current status of remote experimentation designs and how this has impacted our education and research activities with a notion that whether we are moving too fast while its acceptance has not yet realized. While for the second part, the author will describe some of the developments of remote experiment designs through his own work. Researchers have been working on remote experimentations for a considerable period of time and are making remarkable breakthroughs utilizing cutting edge technologies and current understanding of educational and learning strategies. After all of these developments, the popularity of remote experimentations is still very limited and does not have the attention of the academic community to incorporate them as a part of their regular curriculum. There are a number of factors that hinder acceptance of remote laboratories as a part of a curriculum. These are integration of a number of areas, modular designs, commercial products, maintenance, and administrative support. The paper will address these issues and will highlight how we can move forward in a coordinated manner so there will be a viable remote experimentation infrastructure with a high degree of acceptance. The author has a number of federal research grants (USA where he has developed Internet accessible remote experimentation facilities. These facilities have features like use of single computer for accessing multiple experiments, manipulating experimental setup from remote locations, integrated assessment, and real-time learning management features. The developed facilities have used for delivering a number of experiment courses, while gathering data in terms of achieving learning outcomes and assessing the effectiveness of the system in terms of system designs.

    Information and Communication Technologies (ICTs) are important tools for development. Despite its significant growth on a global scale, Internet access is limited in sub-Saharan Africa (SSA). Few studies have explored Internet access, use of electronic resources and ICT training among health information professionals in Africa. The study assessed Internet access, use of electronic resources and ICT training among health information professionals in SSA. A 26-item self-administered questionnaire in English and French was used for data collection. The questionnaire was completed by health information professionals from five Listservs and delegates at the 10th biannual Congress of the Association of Health Information and Libraries in Africa (AHILA). A total of 121 respondents participated in the study and, of those, 68% lived in their countries' capital. The majority (85.1%) had Internet access at work and 40.8% used cybercafes as alternative access points. Slightly less than two-thirds (61.2%) first learned to use ICT through self-teaching, whilst 70.2% had not received any formal training in the previous year. Eighty-eight per cent of respondents required further ICT training. In SSA, freely available digital information resources are underutilized by health information professionals. ICT training is recommended to optimize use of digital resources. To harness these resources, intergovernmental and non-governmental organizations must play a key role.

    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.

This survey of 454 adolescents used screening (57/58 and diagnostic (63/64 cut-off points of the CIAS, a self-reported instrument, based on the results of systematic diagnostic interviews by psychiatrists. The area under the curve of the receiver operating characteristic curve revealed that CIAS has good diagnostic accuracy (89.6%. The screening cut-off point had high sensitivity (85.6% and the diagnostic cut-off point had the highest diagnostic accuracy, classifying 87.6% of participants correctly. Accordingly, the screening point of the CIAS could provide a screening function in two-stage diagnosis, and the diagnostic point could serve as a diagnostic criterion in one-stage massive epidemiologic research.

    Full Text Available Internet is well known nowadays, however higher distance education students who live in remote rural areas still have not been able to take advantages of this medium optimally for their learning process. For accessing the internet the students have to be available with the minimum prerequisites: the existence of adequate devices and the sufficient capabilities. For education purposes, the students use the internet to meet their information and fulfill learning needs, facilitate interpersonal communications, and provide groups of discussion, as well as to be connected with friends in social media. This study aims to analyze the relationship between internet access and usage in improving students' self-directed learning which is using structural equation model method. The survey is conducted in seven districts in Surakarta Regional Office of Indonesia Open University with a sample size of 320 respondents. The result shows that the internet usage is still low due to limited internet facilities that affect the knowledge and willingness of students to access the internet. The strategy in improving student internet usage is applying social media as guidance that can be accessed through cellular phones.

    Full Text Available Abstract 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

    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.

    This article discusses the fundamental issues and the technologies to achieve an energy-efficient Gigabit-Ethernet point-to-point (PtP) fiber access network. To minimize the power consumption of PtP fiber access for long-term development, it is essential to optimize each of the network components such as optical transceiver, user network interface, Ethernet aggregator and also their modes of operation. Our analysis shows that the energy consumption of a PtP fiber access network using our proposed technologies can be up to 7.5 times lower than that of the 2010 technologies when a combination of appropriate technologies is applied.

    2013-01-01

    Noncommunicable diseases, such as cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes, are currently the leading causes of death in several regions of the world. The continuing fast increase in the global burden of noncommunicable diseases is accompanied by a speedy worldwide internet access growth. The worldwide number of internet users has doubled over the past five years. As the internet can make the access to information on a healthy lifestyle and disease prevention activities easier, internet access growth may help to promote good health. Against this background, I discuss the roles the internet and access to information can play in health promotion. I also present an open access web portal on local prevention and health promotion activities. It was initiated by two German states to link health information from disparate sources and to organize this information in a user-friendly way. The web portal focuses on reducing preventable lifestyle-related risk factors associated with noncommunicable diseases, including physical inactivity, unhealthy diet, tobacco use, and the harmful use of alcohol. This local initiative has the potential for scaling up and can serve as a blueprint for other areas that have or will acquire internet access.

    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.

    Abstract Voice quality on VoIP communication is caused by many factors, one of which is the quality of the server. Choosing PC platform or server which is suitable is the main issue in developing VoIP network. A bad server performance or not equivalent with the most of users will degrade the sound quality or even not able to connect between users. Tthe test carried out to the performance of the wireless access point Linksys WRT54GL which is used as a VoIP server. The test was carried out to determine how many VoIP calls which are able to be serviced by a wireless access point as a VoIP server and how long the server needs to be able to process every signal of SIP and RTP packet. Based on the test result performed, the VoIP server on the wireless access point is able to serve VoIP communication well for a few calls number, so it is worth to be implemented on the use of small scale. The use of Native Bridging method in handling the media performed by the server can increase the number of calls that were able to be served about 3 to 7 times compared with other methods.     Keywords— VoIP, Asterisk, Acess Point, WRT54GL, OpenWRT, Performance

    China has historically reported a low prevalence of eating disorders. However, the rapid social and economic development of this country as well as Western ideals widely disseminated by television and the Internet have led to distinct patterns of behavioral choices that could affect eating disorder risk. Thus, the current study explored the relation between disordered eating and media use. Participants were females from the 2009 wave of the China Health and Nutrition Survey (N = 1,053). Descriptive statistics were obtained and logistic regression models, stratified by age (adolescents ages 12-17 years and adults ages 18-35 years), were used to evaluate the association of media use with disordered eating. In adolescents, 46.8% had access to the Internet and those with access averaged one hour per day each of Internet and television use. In adults, 41.4% had access to the Internet, and those with access averaged 1 h per day of Internet use and 2 h per day of television use. Internet access was significantly associated with a subjective belief of fatness (OR = 2.8, 95% CI: 1.6, 4.9) and worry over losing control over eating (OR = 4.8, 95% CI: 2.3, 9.8) only in adults. These findings help characterize the overall pattern of media use and report of eating disorder symptoms in a large sample of female Chinese adolescents and adults. That Internet access in adults was significantly associated with disordered eating cognitions might suggest that media access negatively influences these domains; however, more granular investigations are warranted. © 2014 Wiley Periodicals, Inc.

    Full Text Available This work presents an approach to automatically detect structural floor elements such as steps or ramps in the immediate environment of buildings, elements that may affect the accessibility to buildings. The methodology is based on Mobile Laser Scanner (MLS point cloud and trajectory information. First, the street is segmented in stretches along the trajectory of the MLS to work in regular spaces. Next, the lower region of each stretch (the ground zone is selected as the ROI and normal, curvature and tilt are calculated for each point. With this information, points in the ROI are classified in horizontal, inclined or vertical. Points are refined and grouped in structural elements using raster process and connected components in different phases for each type of previously classified points. At last, the trajectory data is used to distinguish between road and sidewalks. Adjacency information is used to classify structural elements in steps, ramps, curbs and curb-ramps. The methodology is tested in a real case study, consisting of 100 m of an urban street. Ground elements are correctly classified in an acceptable computation time. Steps and ramps also are exported to GIS software to enrich building models from Open Street Map with information about accessible/inaccessible entrances and their locations.

    Full Text Available Nowadays the rapid development of telecommunication services is increasingly evident and undeniable. In order to adapt to constant changes, telecommunication services providers and network operators must follow the requirements of the market and adapt service portfolio they offer. The existence of pre-defined package of services can meet the requirements of a labor market. Combining different services and their delivery to the location of the end user facilitates business to the companies. A flexible approach to creating solutions to connect to the Internet enables the operator to keep position among the leaders in the telecommunications market. However, large companies usually have complex and specific requirements. Specific requirements are usually related to the quality of data transmission and data security. Therefore, different solutions are tailor-made and applied by the business users. The specific requirements of the user described in this paper refer to the maximum availability of Internet connection at the location of the customer, which includes the delivery of two independent Internet links as well as adequate equipment to perform switching from the primary to the redundant (backup link in the event of interruption or major degradation of quality of service.

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

    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.

    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.

    2015-07-01

    Full Text Available Introduction: The association between pornography and sexual crime is controversial, with various researchers finding positive, no, or negative associations. Recent evidence suggests that there may be a specific association between child pornography, which is easily available on the Internet, and sexual offences against children. Methods: Using methodology similar to an earlier study from India, we obtained official statistics on sexual offences against children, namely rape and procurement of minor girls, for the period 2000-2012 from the National Crime Records Bureau. We analysed the association between the rates of these crimes and Internet access, measured by the number of users per 1,00,000 people. Results: Even after correcting for population growth, we found significant linear associations between Internet availability and the rates of both these offences against children. However, there was no correlation between the growth rate of Internet access and the rate of increase of these crimes. Discussion: While the association between pornography and the rape of adults is still under debate, our results provide indirect evidence of a possible association between Internet availability and sexual crimes against children. Regulation of the Internet to suppress access to child pornography may prevent at least some of these crimes.

    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.

    2018-02-26

    The purpose of this study is to systematically review published evidence regarding the development, use and effectiveness of assistive devices and technologies that enable internet access for individuals who are deafblind. Eight electronic research databases (CINAHL, Embase, Engineering Village MEDLINE, PsycINFO, PubMed, Cochrane Library, and Web of Science) and three clinical trials registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials,gov) were searched. Seven articles met the inclusion criteria for this systematic review. The assistive technologies described were in the preliminary stages of development, with only three of the technologies having undergone any testing. The effectiveness of all seven assistive technologies was quantified in this review based on the proposed impacts of internet access on the domains of the World Health Organization's International Classification of Functioning, Disability and Health framework. Internet access technologies for individuals with deafblindness are in the early stages of development and are targeted towards specific functions of the internet. It is imperative that future device development and evaluation seek input from persons who are deafblind. There is also a need to address the gap between academic research which seeks to develop assistive technology to access the internet and the translation into real world use of this technology.

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.

    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.

    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.

    The Internet of Things is one of the ideas that has become increasingly relevant in recent years. It involves connecting things to the Internet in order to retrieve information from them at any time and from anywhere. In the Internet of Things, sensor networks that exchange information wirelessly via Wi-Fi, Bluetooth, Zigbee or RF are common. In this sense, our paper presents a way in which each classroom control is accessed through Near Field Communication (NFC) and the information is shared via radio frequency. These data are published on the Web and could easily be used for building applications from the data collected. As a result, our application collects information from the classroom to create a control classroom tool that displays access to and the status of all the classrooms graphically and also connects this data with social networks.

  8. Local government broadband policies for areas with limited Internet access

    Directory of Open Access Journals (Sweden)

    Yoshio Arai

    2014-03-01

    Full Text Available Despite their wide diffusion in developed countries, broadband services are still limited in areas where providing them is not profitable for private telecom carriers. To address this, many local governments in Japan have implemented broadband deployment projects subsidized by the national government. In this paper, we discuss local government broadband policies based on survey data collected from municipalities throughout the country. With the support of national promotion policies, broadband services were rapidly introduced to most local municipalities in Japan during the 2000s. Local government deployment policies helped to reduce the number of areas with no broadband access. A business model based on the Indefeasible Right of Use (IRU contract between a private telecom carrier and a local government has been developed in recent years. Even local governments without the technical capacity to operate a broadband business can introduce broadband services into their territory using the IRU business model.

  9. Illegal "no prescription" internet access to narrow therapeutic index drugs.

    Liang, Bryan A; Mackey, Tim K; Lovett, Kimberly M

    2013-05-01

    Narrow therapeutic index (NTI) drugs, because of proximity of therapeutic amounts to toxic amounts, require close professional oversight, particularly when switching formulations. However, safe use may be compromised by unsupervised switching through access to online "no prescription" Web sites. We assessed no prescription online availability of NTI drugs, using an academically published list (core NTI drugs). Using the Google search term "buy DRUG no prescription," we reviewed the first 5 search result pages for marketing of no prescription NTI drugs. We further assessed if National Association of Boards of Pharmacy (NABP) Not Recommended vendors were marketing NTI drugs. Searches were conducted from November 3, 2012 to January 3, 2013. For core NTI drugs, we found 13 of 14 NTI drugs (92%) marketed as available without prescription, all from NABP Not Recommended vendors. On the basis of these initial findings, we expanded our core list to 12 additional NTI drugs; 11 of 12 of these drugs (92%) were available from no prescription Web sites. Overall, 24 of 26 NTI drugs (92%) were illegally marketed as available online without the need for a prescription. Suspect online NTI drug access from no prescription vendors represents a significant patient safety risk because of potential patient drug switching and risk of counterfeit versions. Further, state health care exchanges with coverage limitations may drive patients to seek formulations online. Food and Drug Administration harmonization with tighter international NTI drug standards should be considered, and aggressive action against suspect online marketers should be a regulatory and public health priority.

    Full Text Available The last decade has producted a revolution in the world of Internet and computer technology for many disabled people. Especially, with the help of adaptive technology, for example, deaf-blind people can communicate over telephone networks and severely visaully impaired people can read a computer screen directly with the help of speech synthesis or automatically generated Braille displays. People with physical disabilities can use personel computers by blowing. If s even possible to control computers by using the voice. However, currently, the largest problem is that WWW pages are increasingly developed with pictures, images, audio and video clips carrying much of the information. For this reason, the aims of this article are twofold: first, to give some information about products of adaptive technologies for people with disabilities, and second, to give some design examples about Web pages for this people. Son 10 yıl içinde, engellilere yönelik Internet ve bilgisayar teknolojisi alanında yeni bir oluşum yaşanmaya başlandı.

    One of the most important issues in wireless local area network (WLAN) systems with multiple access points (APs) is the AP selection problem. Game theory is a mathematical tool used to analyze the interactions in multiplayer systems and has been applied to various problems in wireless networks. Correlated equilibrium (CE) is one of the powerful game theory solution concepts, which is more general than the Nash equilibrium for analyzing the interactions in multiplayer mixed strategy games. A game-theoretic formulation of the AP selection problem with mobile users is presented using a novel scheme based on a regret-based learning procedure. Through convergence analysis, we show that the joint actions based on the proposed algorithm achieve CE. Simulation results illustrate that the proposed algorithm is effective in a realistic WLAN environment with user mobility and achieves maximum system throughput based on the game-theoretic formulation.

    Science.gov (United States)

    Masters, Ken

    2008-11-01

    In the developed world, doctors use the Internet to support the delivery of health care. Their usage patterns are explained by Rogers' Diffusion of Innovations. There is no knowledge of Internet usage by doctors in the developing world. In July 2006, 2600 survey forms were posted in the first national survey of South African (SA) General Practitioners' (GPs) use of the Internet. A sample of non-responders was followed up. The aim was to determine SA GPs' Internet usage patterns, to compare them to world usage, and to examine them in the light of Diffusion of Innovations. A 10% usable response rate was a major weakness, but similar surveys are unlikely to be more representative. 89% of SA GPs have Internet access, home usage is high, and overall usage patterns are equivalent to the usage patterns of international studies. In spite of the overall technological under-development in South Africa, as predicted by Diffusion of Innovations, SA GPs have adopted the technology, and use it for health care in much the same way as their international counterparts. Further studies on some of the details will be valuable. The indications are that SA GPs will reap the benefits of the Internet as it continues to evolve, and translate these into improved health care delivery in South Africa.

    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.

    Poirier, S.; Buteau, A.; Ounsy, M.; Rodriguez, C.; Hauser, N.; Lam, T.; Xiong, N.

    2012-01-01

    For almost 20 years, the scientific community of neutron and synchrotron institutes have been dreaming of a common data format for exchanging experimental results and applications for reducing and analyzing the data. Using HDF5 as a data container has become the standard in many facilities. The big issue is the standardization of the data organization (schema) within the HDF5 container. By introducing a new level of indirection for data access, the Common-Data-Model-Access (CDMA) framework proposes a solution and allows separation of responsibilities between data reduction developers and the institute. Data reduction developers are responsible for data reduction code; the institute provides a plug-in to access the data. The CDMA is a core API that accesses data through a data format plug-in mechanism and scientific application definitions (sets of keywords) coming from a consensus between scientists and institutes. Using a innovative 'mapping' system between application definitions and physical data organizations, the CDMA allows data reduction application development independent of the data file container AND schema. Each institute develops a data access plug-in for its own data file formats along with the mapping between application definitions and its data files. Thus data reduction applications can be developed from a strictly scientific point of view and are immediately able to process data acquired from several institutes. (authors)

    Internet of Things (IoT) becomes discretionary part of everyday life. Scalability and manageability is daunting due to unbounded number of devices and services. Access control and authorization in IoT with least privilege is equally important to establish secure communication between multiple...... devices and services. In this paper, the concept of capability for access control is introduced where the identities of the involved devices are entrenched in the access capabilities. Identity driven capability based access control (ICAC) scheme presented in this paper helps to alleviate issues related...... to complexity and dynamics of device identities. ICAC is implemented for 802.11 and results shows that ICAC has less scalability issues and better performance analysis compared with other access control schemes. The ICAC evaluation by using security protocol verification tool shows that ICAC is secure against...

    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.

    Byun, Tae-Young

    This paper presents a prototype of inter-vehicle communication system using mobile access point that internetworks wired or wireless LAN and wireless WAN anywhere. Implemented mobile access point can be equipped with various wireless WAN interfaces such as WCDMA and HSDPA. Mobile access point in the IP mechanism has to process connection setup procedure to one wireless WAN. To show the applicability of the mobile access point to inter-vehicle communication, a simplified V2I2V-based car communication system called ICSW2AN is implemented to evaluate major performance metrics by road test. In addition, results of road test for traffic information service are investigated in view of RTT, latency and server processing time. The experimental result indicates that V2I2V-based car communication system sufficiently can provide time-tolerant traffic information to moving vehicles while more than two mobile devices in restricted spaces such as car, train and ship access wireless Internet simultaneously.

    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.

    Quantitative knowledge of the magnitude, extent and trends of the Digital Divide are critical to understand and identify the regions most in need of help, to make rational decisions on how to address the problems and to make cases for executives, funding agencies and politicians. We report on a project (PingER) to measure the Digital Divide from the point of view of Internet performance. The PingER project has been measuring Internet performance since 1995 and with the increased emphasis on measuring and tracking the Digital Divide, it now covers over 700 hosts in over 150 countries that between them contain over 99% of the world's Internet connected population. In this paper we will describe the how PingER works, it deployment, the data analysis, and presentation. We also introduce a new PingER visualization tool (ViPER) that provides a more appealing interactive visualization of the PingER data and also works on mobile PDAs. We will also show results from PingER that illustrate the magnitude, extent and trends for the Digital Divide, and also compare PingER results with some human development and technology indices.

    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.

    As health care costs alarm the nation and the debate increases about the impact of health information technologies, patients are reviewing their medical records increasingly through secure Internet portals. Important questions remain about the impact of portal use on office visits. To evaluate whether use of patient Internet portals to access records is associated with increased primary care utilization. A prospective cohort study. Primary care patients registered on patient Internet portals, within an integrated health system serving rural Pennsylvania and an academic medical center in Boston. Frequency of "clinical portal use" (days/2 mo intervals over 2 y) included secure messaging about clinical issues and viewing laboratory and radiology findings. In year 2, a subset of patients also gained access to their primary care doctor's visit notes. The main outcome was number of primary care office visits. In the first 2 months of the 2-year period, 14% of 44,951 primary care patients engaged in clinical portal use 2 or more days per month, 31% did so 1 day per month, and the remainder had no clinical portal use. Overall, adjusted for age, sex, and chronic conditions, clinical portal use was not associated with subsequent office visits. Fewer than 0.1% of patients engaged in high levels of clinical portal use (31 or more login days in 2 mo) that were associated with 1 or more additional visits in the subsequent 2 months (months 3 and 4). However, the reverse was true: office visits led to subsequent clinical portal use. Similar trends were observed among patients with or without access to visit notes. Patients turn to their portals following visits, but clinical portal use does not contribute to an increase in primary care visits.

    This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications (WAI-ARIA) suite, developed by the World Wide Web Consortium (W3C) within the framework of the Web Accessibility Initiative (WAI). Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.

    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

    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.

    With the increasing convenience of social networking sites and their interconnectedness with human interaction, verbal and image bullying have turned digital, making cyberbullying a new form of bullying attracting the attention of researchers, social workers, and schools. This study focuses on the status quo of attitude toward cyberbullying and cyberbullying behavior, explores associations of attitude toward behavior on cyberbullying behavior in gender and different internet access times. In a cross-sectional survey, adolescents were surveyed through self-report questionnaires, 13,864 respondents were received among 150 high schools in Taiwan. Statistical analyses were performed using structural equation modeling (SEM). The study revealed that attitude toward cyberbullying has a direct effect on cyberbullying behavior; among the greatest direct impact were when students use the Internet during the time frame 10:00–14:00. Parents and schoolteachers pay special attention to students using the Internet during this time frame 10:00–14:00 and give guidance, express care, and help those being bullied to communicate and use the Internet in a correct manner. Among genders, male student attitude toward behavior has a greater effect than those of female students. Both male and female students know what cyberbullying is and have witnessed, heard of, or personally encountered cyberbullying behavior. We recommend students talk to parents or teachers or other people who care to reduce the negative effects of cyberbullying. We hopeful that the conceptualization model presented in this study serves as an activator for researches on attitude toward cyberbullying and cyberbullying behavior, and serves a guide and a call to attract more researches in this area.

    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

    Highway Capacity Manual 2010 provides various factors to adjust the base saturation flow rate for the capacity analysis of signalized intersections. No factors, however, is considered for the potential change of signalized intersections capacity caused by the access point closeing to the signalized intersection. This paper presented a theoretical model to estimate the lane group capacity at signalized intersections with the consideration of the effects of access points. Two scenarios of access point locations, upstream or downstream of the signalized intersection, and impacts of six types of access traffic flow are taken into account. The proposed capacity model was validated based on VISSIM simulation. Results of extensive numerical analysis reveal the substantial impact of access point on the capacity, which has an inverse correlation with both the number of major street lanes and the distance between the intersection and access point. Moreover, among the six types of access traffic flows, the access traffic flow 1 (right-turning traffic from major street), flow 4 (left-turning traffic from access point), and flow 5 (left-turning traffic from major street) cause a more significant effect on lane group capacity than others. Some guidance on the mitigation of the negative effect is provided for practitioners.

No factors, however, is considered for the potential change of signalized intersections capacity caused by the access point closeing to the signalized intersection. This paper presented a theoretical model to estimate the lane group capacity at signalized intersections with the consideration of the effects of access points. Two scenarios of access point locations, upstream or downstream of the signalized intersection, and impacts of six types of access traffic flow are taken into account. The proposed capacity model was validated based on VISSIM simulation. Results of extensive numerical analysis reveal the substantial impact of access point on the capacity, which has an inverse correlation with both the number of major street lanes and the distance between the intersection and access point. Moreover, among the six types of access traffic flows, the access traffic flow 1 (right-turning traffic from major street, flow 4 (left-turning traffic from access point, and flow 5 (left-turning traffic from major street cause a more significant effect on lane group capacity than others. Some guidance on the mitigation of the negative effect is provided for practitioners.

    The aim of this research forum article was to examine accessibility, use, and adherence to computerized and online interventions for people with hearing loss. Four intervention studies of people with hearing loss were examined: 2 auditory training studies, 1 working memory training study, and 1 study of multimedia educational support. A small proportion (approximately 15%) of participants had never used a computer, which may be a barrier to the accessibility of computer and Internet-based interventions. Computer competence was not a factor in intervention use or adherence. Computer skills and Internet access influenced participant preference for the delivery method of the multimedia educational support program. It is important to be aware of current barriers to computer and Internet-delivered interventions for people with hearing loss. However, there is a clear need to develop and future-proof hearing-related applications for online delivery.

    Full Text Available Abstract—Immersive 3D worlds have increasingly raised the interest of researchers and practitioners for various learning and training settings over the last decade. These virtual worlds can provide multiple communication channels between users and improve presence and awareness in the learning process. Consequently virtual 3D environments facilitate collaborative learning and training scenarios. In this paper we focus on the integration of internet-accessible physics experiments (iLabs combined with the TEALsim 3D simulation toolkit in Project Wonderland, Sun's toolkit for creating collaborative 3D virtual worlds. Within such a collaborative environment these tools provide the opportunity for teachers and students to work together as avatars as they control actual equipment, visualize physical phenomenon generated by the experiment, and discuss the results. In particular we will outline the steps of integration, future goals, as well as the value of a collaboration space in Wonderland's virtual world.

    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.

    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.

    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, Pinternet 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.

    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.

  1. 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

    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

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.

    Diplomates in the American Board of Internal Medicine (ABIM) Maintenance of Certification (MOC) program satisfy the self-evaluation of medical knowledge requirement by completing open-book multiple-choice exams. However, this method remains unlikely to affect practice change and often covers content areas not relevant to diplomates' practices. We developed and evaluated an Internet-based point of care (POC) learning portfolio to serve as an alternative. Participants enter information about their clinical questions, including characteristics, information pursuit, application, and practice change. After documenting 20 questions, they reflect upon a summary report and write commitment-to-change statements about their learning strategies. They can link to help screens and medical information resources. We report on the beta test evaluation of the module, completed by 23 internists and 4 internal medicine residents. Participants found the instructions clear and navigated the module without difficulty. The majority preferred the POC portfolio to multiple-choice examinations, citing greater relevance to their practice, guidance in expanding their palette of information resources, opportunity to reflect on their learning needs, and "credit" for self-directed learning related to their patients. Participants entered a total of 543 clinical questions, of which 250 (46%) resulted in a planned practice change. After completing the module, 14 of 27 (52%) participants committed to at least 1 change in their POC learning strategies. Internists found the portfolio valuable, preferred it to multiple-choice examinations, often changed their practice after pursuing clinical questions, and productively reflected on their learning strategies. The ABIM will offer this portfolio as an elective option in MOC.

    1996-01-01

    Internet access to mixed text/image databanks is finding application in the medical world. An example is a database of medical X-rays and associated data consisting of demographic, socioeconomic, physician's exam, medical laboratory and other information collected as part of a nationwide health survey conducted by the government. Another example is a collection of digitized cryosection images, CT and MR taken of cadavers as part of the National Library of Medicine's Visible Human Project. In both cases, the challenge is to provide access to both the image and the associated text for a wide end user community to create atlases, conduct epidemiological studies, to develop image-specific algorithms for compression, enhancement and other types of image processing, among many other applications. The databanks mentioned above are being created in prototype form. This paper describes the prototype system developed for the archiving of the data and the client software to enable a broad range of end users to access the archive, retrieve text and image data, display the data and manipulate the images. System design considerations include; data organization in a relational database management system with object-oriented extensions; a hierarchical organization of the image data by different resolution levels for different user classes; client design based on common hardware and software platforms incorporating SQL search capability, X Window, Motif and TAE (a development environment supporting rapid prototyping and management of graphic-oriented user interfaces); potential to include ultra high resolution display monitors as a user option; intuitive user interface paradigm for building complex queries; and contrast enhancement, magnification and mensuration tools for better viewing by the user.

    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

    Language interface plays a critical role as the foundation of communication. Possessing greater fluency in the host language can lead to increased opportunities for interaction with host members. This research is to examine the impact of language and Internet usage anxiety and self-efficacy on the intended uses of Internet sites, respectively. 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.

    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.

  15. A fragmentation model of earthquake-like behavior in internet access activity

    Paguirigan, Antonino A.; Angco, Marc Jordan G.; Bantang, Johnrob Y.

    We present a fragmentation model that generates almost any inverse power-law size distribution, including dual-scaled versions, consistent with the underlying dynamics of systems with earthquake-like behavior. We apply the model to explain the dual-scaled power-law statistics observed in an Internet access dataset that covers more than 32 million requests. The non-Poissonian statistics of the requested data sizes m and the amount of time τ needed for complete processing are consistent with the Gutenberg-Richter-law. Inter-event times δt between subsequent requests are also shown to exhibit power-law distributions consistent with the generalized Omori law. Thus, the dataset is similar to the earthquake data except that two power-law regimes are observed. Using the proposed model, we are able to identify underlying dynamics responsible in generating the observed dual power-law distributions. The model is universal enough for its applicability to any physical and human dynamics that is limited by finite resources such as space, energy, time or opportunity.

    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.

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

    The increasing volume of information available on the Internet today is a problem for health care professionals who want to access rapidly data of high quality. Usual search engines and directories are not sufficient to satisfy their needs. Moreover, the information published by Web sites is not always guaranteed. Some institutions around the word deal with the definition of a set of criteria for the evaluation of medical Web sites. We base our current work on the technologies we developed previously in order to integrate sources of information of various kinds using the "Unified Medical Language System" knowledge bases. This paper focuses on quality criteria and access characteristics Web sites should satisfy to be registered in a "Health Internet Directory". The design of such a system is proposed and discussed.

  20. 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.

    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.

    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

    Objective To determine if secondary school students in New Zealand who report greater health concerns (e.g. significant depressive symptoms) are more likely to use the Internet to access health-related information. Methods A nationally representative health and wellbeing survey was undertaken in 2012 (n = 8500). Multiple regression models were used to examine the associations between students' use of the Internet to access health-related information and selected outcomes or indicators. Results Over 90% of students used the Internet on a daily basis, with 15.4% of students reporting that they had used the Internet to access health-related information. Students experiencing household poverty were more likely to report not using the Internet daily (17.4% compared to 4.2%). Odds ratios (ORs) for accessing the Internet for this sort of information were highest for students who reported self-harm [OR 2.7, 95% confidence interval (CI) 2.3-3.3], disordered eating (OR 2.7, 95% CI 2.4-3.2), or a suicide attempt (OR 2.5, 95% CI 1.9-3.3). Conclusion Our findings suggest that Internet-based health interventions may be a viable way to reach young people with high health needs, but consideration needs to be given to those with limited Internet access.

    The Internet is increasingly used in mental health service delivery, but there are significant potential barriers to Internet access for persons with severe mental illness (SMI). There is a need to understand this group's access to, and confidence with using, the Internet, and current views on using online resources as part of mental healthcare. A survey was conducted of 100 consumers attending a specialist mental health service in Melbourne, Australia. Approximately three-quarters of participants had regular access to the Internet, and two-thirds used the Internet weekly or more. Half of the sample used email at least weekly, and a third were regular users of social networking sites. Internet access was often via mobile devices. Only a minority of participants used the Internet for mental health information, with video streaming and general websites accessed more often than peer forums for mental health content. Most participants were positive about their mental health worker using tablet computers with them in appointments for delivery of mental health materials. Most people with SMI are active Internet users and, therefore, able to use interventions online.

    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.

    The need for surgical outcomes data is increasing due to pressure from insurance companies, patients, and the need for surgeons to keep their own "report card". Current data management systems are limited by inability to stratify outcomes based on patients, surgeons, and differences in surgical technique. Surgeons along with research and informatics personnel from an academic, hospital-based Department of Surgery and a state university's Department of Information Technology formed a partnership to develop a dynamic, internet-based, clinical data warehouse. A five-component model was used: data dictionary development, web application creation, participating center education and management, statistics applications, and data interpretation. A data dictionary was developed from a list of data elements to address needs of research, quality assurance, industry, and centers of excellence. A user-friendly web interface was developed with menu-driven check boxes, multiple electronic data entry points, direct downloads from hospital billing information, and web-based patient portals. Data were collected on a Health Insurance Portability and Accountability Act-compliant server with a secure firewall. Protected health information was de-identified. Data management strategies included automated auditing, on-site training, a trouble-shooting hotline, and Institutional Review Board oversight. Real-time, daily, monthly, and quarterly data reports were generated. Fifty-eight publications and 109 abstracts have been generated from the database during its development and implementation. Seven national academic departments now use the database to track patient outcomes. The development of a robust surgical outcomes database requires a combination of clinical, informatics, and research expertise. Benefits of surgeon involvement in outcomes research include: tracking individual performance, patient safety, surgical research, legal defense, and the ability to provide accurate information

    Full Text Available Abstract Background Comparative genomics has become a significant research area in recent years, following the availability of a number of sequenced genomes. The comparison of genomes is of great importance in the analysis of functionally important genome regions. It can also be used to understand the phylogenetic relationships of species and the mechanisms leading to rearrangement of karyotypes during evolution. Many species have been studied at the cytogenetic level by cross species chromosome painting. With the large amount of such information, it has become vital to computerize the data and make them accessible worldwide. Chromhome http://www.chromhome.org is a comprehensive web application that is designed to provide cytogenetic comparisons among species and to fulfil this need. Results The Chromhome application architecture is multi-tiered with an interactive client layer, business logic and database layers. Enterprise java platform with open source framework OpenLaszlo is used to implement the Rich Internet Chromhome Application. Cross species comparative mapping raw data are collected and the processed information is stored into MySQL Chromhome database. Chromhome Release 1.0 contains 109 homology maps from 51 species. The data cover species from 14 orders and 30 families. The homology map displays all the chromosomes of the compared species as one image, making comparisons among species easier. Inferred data also provides maps of homologous regions that could serve as a guideline for researchers involved in phylogenetic or evolution based studies. Conclusion Chromhome provides a useful resource for comparative genomics, holding graphical homology maps of a wide range of species. It brings together cytogenetic data of many genomes under one roof. Inferred painting can often determine the chromosomal homologous regions between two species, if each has been compared with a common third species. Inferred painting greatly reduces the need to

    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.

    2012-10-01

    Full Text Available Public authorities and national healthcare service providers across the European Union and beyond are increasingly under pressure to deliver better services with diminishing resources. Users, quite rightly, demand a high standard of service and increasingly also convenience focused on the needs of the users rather than how the services are organised to deliver them. Users, on the whole, also prefer to be supported in their homes, and be free to move as much as possible. While users without impairments and generally well provided for, there are increasingly also users who have special needs, including the aged and those with a range of physical and mental disabilities who are unable to make effective use of such services from their homes due to the lack of proactive and accessible services. The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered for free or purchased through some central form of a marketplace repository.

    According to the Digital Agenda for Europe, the way children use the Internet and mobile technologies has changed dramatically in the past years. 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. 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. 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. Among the results of the third group, we found that 7.69% (118/1534) of the

    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.

    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 socio demographic, 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 socio demographic 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 (O R=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.

    Web sites containing health information should be accessible to visually impaired persons. 139 web sites containing medical information addressing laymen or patients were evaluated with respect to their accessibility. A quantitative checklist which is based upon the Web Content Accessibility Guidelines of the World Wide Web Consortium (W3C) was used. Only 18% (15 sites) achieved WAI (Web Accessibility Initiative) level A or AA. WAI level AA was reached by only 1% (1 site) of the web sites. None of the web sites reached level AAA; 82% of the assessed web sites offering consumer health information are not fully accessible to visually impaired persons. The accessibility of web-based health content to visually impaired users should be improved. Health information on the web should at least meet the requirements of priority 1 (level A), preferably priority 2 (level AA) of the W3C guidelines. (c) 2008 S. Karger AG, Basel

This system also has some teaching functions, improves the analysis of datasets based on calculating the values of the TDS (Total Dermatoscopy Score (Braun-Falco, Stolz, Bilek, Merkle, & Landthaler, 1990; Hippe, Bajcar, Blajdo, Grzymala-Busse, Grzymala-Busse, & Knap, et al., 2003 parameter. Calculations are based on two methods: the classical ABCD formula (Braun-Falco et al., 1990 and the optimized ABCD formula (Alvarez, Bajcar, Brown, Grzymala-Busse, & Hippe, 2003. A third method of classification is devoted to quasi-optimal decision trees (Quinlan, 1993. The developed internet-based tool enables users to make an early, non-invasive diagnosis of melanocytic lesions. This is possible using a built-in set of instructions that animates the diagnosis of the four basic lesions types: benign nevus, blue nevus, suspicious nevus and melanoma malignant.

    Studies show internet sourced information often has poor accuracy. However, it is rapidly becoming a major source of patient information. Our aim was to assess accuracy of breast cancer-related information on the internet. The top five breast cancer-related search terms were identified using the commercial program "Wordtracker". These terms were searched using the search-engine "Google" and the top 100 webpages per topic analysed for applicability and accuracy of information. Overall 500 webpages were analysed. 42% were inapplicable to the question asked. Applicable accuracy rates were variable amongst the five terms: "breast cancer symptoms" 84%, "breast cancer care" 87%, "breast cancer stage" 88%, "breast cancer survival" 91% and "breast cancer signs" 78%. Educational websites were more likely to be accurate(p < 0.001) and interest group administered websites less likely to be accurate(p = 0.018) than other websites. Finding accurate breast cancer information on the internet is difficult due to large numbers of inapplicable unregulated websites preferentially returned via search engines.

    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.

    In IEEE 802.11 networks, the access point (AP) selection based on the strongest signal strength often results in the extremely unfair bandwidth allocation among mobile users (MUs). In this paper, we propose a distributed AP selection algorithm to achieve a fair bandwidth allocation for MUs. The proposed algorithm gradually balances the AP loads based on max-min fairness for the available multiple bit rate choices in a distributed manner. We analyze the stability and overhead of the proposed algorithm, and show the improvement of the fairness via computer simulation.

    Full Text Available This paper proposes a location authentication method to prevent wormhole payment attack in Samsung Pay. The primary feature of this method is comparing wireless Access Point (AP information collected by the current Samsung Pay user and a wireless AP model (WM that was created from wireless AP information (WI sent by previous Samsung Pay users. To create the WM, an autoencoder is used. Unlike the existing location authentication techniques that use WI, our method does not require additional hardware, modification of the Point of Sale (POS software, or any pre-requisite information such as the location coordinates of the POS. We show that the proposed location authentication technique exhibits the minimum Equal Error Rate (EER of 2.4% in real payment environments.

    Internationally, generic medicines are increasingly seen as a key strategy to reduce healthcare expenditure, therefore awareness and knowledge transfer regarding generic medicines are valid areas of research. Although the Internet is a frequently used source of medical information, the accuracy of material found online is variable. The aim of this study was to evaluate information provided on the Internet regarding generic medicines in terms of quality of information and readability. Internet searches for information regarding generic medicine were completed, with a pre-defined search term, using the Google search engine, in five English-speaking geographical regions (US, UK, Ireland, Canada and Australia). Search results likely to be looked at by a searcher were collated and assessed for the quality of generic medicine-related information in the websites, using a novel customised Website Quality Assessment (WQA) tool; and for readability, using existing methods. The reproducibility of the tools between two independent reviewers was evaluated and correlations between WQA score, readability statistics and Google search engine results page ranking were assessed. Wikipedia was the highest-ranking search result in 100% of searches performed. Considerable variability of search results returned between different geographical regions was observed, including that websites identified in the Australian search generated the highest number of country specific websites; searches performed using computers with Irish, British, American and Canadian IP addresses appear to be more similar to each other than the google.com search performed in Australia; and the Canadian google.ca results show a notable difference from any of the other searches. Of the 24 websites assessed, none scored a perfect WQA score. Notably, strong correlation was seen between WQA and readability scores and ranking on google.com search results.

    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.

    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.

    We explore a 3D cross-point spin transfer torque magnetic random access memory (STT-MRAM) array based on the integration of a perpendicular magnetic tunneling junction (pMTJ) with a matching two-terminal selector. The integrated two-terminal device provides a unique opportunity for a high density, low cost stackable storage class memory that can achieve a fast operation speed, long data retention, low bit error rate (BER) and high endurance. 55nm size pillar shaped pMTJ and selector devices have been fabricated and characterized. The selector is compatible with pMTJ whether it is in the high or low resistance state. The pMTJ can be RESET and SET after the selector turns on. We model the dynamic switching of the coupled pMTJ and selector devices. Our model shows the importance of the optimal matching of pMTJ magnetic properties with selector resistive properties to achieve high performance.

    1999-01-01

    Although electronic medical records and a central database have made accurate and consistent patient medical information more readily available than with the traditional patient chart, there are many locations in healthcare facilities where terminals for accessing patient data are not available. As patient care becomes decentralized and more patients require anesthesia outside of the operating suites, routing a network-based system to all these locations can be expensive and time consuming. We designed a system whereby essential patient data of interest to anesthesiologists is stored on an electronic memory device the size of a watch battery attached to the patient's wristband. Accessing and editing the data is done via a hand-held computer. This system provides secure patient data storage and management at the "point of care." At the conclusion of the patient's anesthesia-related care, the data is downloaded to a relational database for use in outcome analysis, billing, and quality assurance. After collecting preoperative evaluations, intraoperative data, and postoperative data on 560 patients anesthetized for surgery or other procedures, we find this system to be a reliable, low-cost, medical information management system, with possible application to other medical specialties.

Under NextView contract terms, those engaged in official government programs/projects can gain online access to NGA's vast global archive. Additionally, data from vendor's archives of IKONOS-2 (IK-2), OrbView-3 (OB-3), GeoEye-1 (GE-1), QuickBird-1 (QB-1), WorldView-1 (WV-1), and WorldView-2 (WV-2), sensors can also be requested under these agreements. We report here the current extent of this archive, how to gain access, and the applications of these data by Earth science investigators to improve discoverability and community use of these data. Satellite commercial quality imagery (CQI) at very high resolution (data source to U.S. federal, state, and local governments for many different purposes. The rapid growth of free global CQI data has been slow to disseminate to NASA Earth Science community and programs such as the Land-Cover Land-Use Change (LCLUC) program which sees potential benefit from unprecedented access. This article evolved from a workshop held on February 23rd, 2012 between representatives from NGA, NASA, and NASA LCLUC Scientists discussion on how to extend this resource to a broader license approved community. Many investigators are unaware of NGA's archive availability or find it difficult to access CQI data from NGA. Results of studies, both quality and breadth, could be improved with CQI data by combining them with other moderate to coarse resolution passive optical Earth observation remote sensing satellites, or with RADAR or LiDAR instruments to better understand Earth system dynamics at the scale of human activities. We provide the evolution of this effort, a guide for qualified user access, and describe current to potential use of these

    Memory and interest respond in similar ways to people's shifting needs and motivations. We therefore tested whether memory and interest might produce similar, observable patterns in people's responses over time. Specifically, the present studies examined whether fluctuations in widespread interest (as measured by Internet search trends) resemble two well-established memory patterns: memory decay and goal-related memory accessibility. We examined national and international events (e.g., Nobel Prize selections, holidays) that produced spikes in widespread interest in certain people and foods. When the events that triggered widespread interest were incidental (e.g., the death of a celebrity), widespread interest conformed to memory decay patterns: It rose quickly, fell slowly according to a power function, and was higher after the event than before it. When the events that triggered widespread interest were goal related (e.g., political elections), widespread interest conformed to patterns of goal-related memory accessibility: It rose slowly, fell quickly according to a sigmoid function, and was lower after the event than before it. Fluctuations in widespread interest over time are thus similar to standard memory patterns observed at the individual level due perhaps to common mechanisms and functions.

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

    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.

    Rural GPs play a significant role in the mental health care of their patients. It is therefore crucial that they have access to reputable support and advice that enhances their existing knowledge. This article outlines a recent project initiated by the Australian rural Ballarat and District Division of General Practice (BDDGP) to develop and implement an online resource to facilitate local implementation and delivery of the 'Better Access to Mental Health Care' (BAMHC) program. This 12 month project was initiated in response to a request from local GPs for additional information about and support in using the BAMHC program. The project is the culmination of significant collaboration among key stakeholders that includes local GPs, GP advisors from BDDGP, BDDGP staff, and two University of Ballarat research centres (the Centre for Health Research and Practice, and the Centre for Electronic Commerce and Communication). This article documents the key stages involved in the project from initiation to implementation, and reports on the use of this resource 12 months after its launch. The BDDGP represents 107 GPs and six GP registrars and covers a large rural/semi-rural area of 7300 km2 and a catchment population of more than 120,000. The format and design of the project entailed four distinct but interrelated stages of development: (1) developing the program specifications and localising it to the BDDGP catchment; (2) constructing a decision-making support tool with 7 sequential steps comprising key questions and links to detailed answers; (3) developing and populating an online service directory of local allied health professionals; and (4) constructing the website for easy access and navigation for GPs and other service providers. The website was publicly launched in December 2007 and is hosted by BDDGP. Since then it has received strong support. In the 12 months since its launch the website received regular and continuous visits (2847 visits/11,500 pages accessed). In

    Full Text Available VoIP is a system that uses the Internet network to transmit voice packets from one place to another using IP protocols intermediaries. With VoIP technology can be much cheaper call charges, especially for communicating overseas because of voice and data using the same network ie the Internet network. VoIP is a service that is very susceptible to delay while the existing access network is currently providing a significant delay for VoIP. One alternative network that can be used to overcome these problems is to use WiMAX technology because WiMAX can provide speed data services up to 70 Mbps.From the research,  results of one way delay, jitter and packet loss still at the value recommended by ITU-T, which is the maximum value of one way delay measurement is 159.87 ms, for jitter 7.52 ms and for packet loss is 3.175%. The one way delay and packet loss from the measurement used to find the MOS score which is the value for quality of VoIP. MOS value range obtained from the calculation of 3.6 to 4.2, which means VoIP feasible to apply to the WiMAX network. The maximum value can reach 2.8 Mbps throughput to 0.575 Mbps for downlink and uplink. From the research also found that the SQI values that are above the standard value of the device will provide a high SNR value, and the higher SQI values then its RSSI value is also bigger.

  16. Reduced-complexity adaptive multi-channel assignment for shared access points in over-loaded small-cell networks

    2013-06-01

    This paper proposes a reduced-complexity downlink multi-channel assignment scheme when feedback links are capacity-limited. The system model treats the case when multiple access points are allocated to serve scheduled users in over-loaded (i.e. dense) pico/femtocell networks. It assumes that the deployed access points can be shared simultaneously and employ isotropic antenna arrays of arbitrary sizes. Moreover, they transmit their data on a common physical channel and can not coordinate their transmissions. On the other hand, each scheduled user can be served by single transmit channel from each active access point at a time, and it lacks coordination with concurrent active users. The scheme operates according to the occupancy of available transmit channels, wherein extensively occupied access points are avoided adaptively, while reducing the load of processing. The operation is linked to a target performance via controlling the observed aggregate interference from the projected set of serving points. Through the analysis, results for the scheduled user outage performance, and the average number of active access points are presented. Numerical and simulations studies clarify the gains of the proposed scheme for different operating conditions. © 2013 IEEE.

    The volume of health information necessary to provide competent health care today has become overwhelming. Mobile computing devices are fast becoming an essential clinical tool for accessing health information at the point-of-care of patients. This study explored and described how registered nurses experienced accessing information at the point-of-care via mobile computing devices (MCDs). A qualitative, exploratory, descriptive and contextual design was used. Ten in-depth interviews were conducted with purposively sampled registered nurses employed by a state hospital in the Nelson Mandela Bay Municipality (NMBM). Interviews were recorded, transcribed verbatim and analysed using Tesch's data analysis technique. Ethical principles were adhered to throughout the study. Guba's model of trustworthiness was used to confirm integrity of the study. Four themes emerged which revealed that the registered nurses benefited from the training they received by enabling them to develop, and improve, their computer literacy levels. Emphasis was placed on the benefits that the accessed information had for educational purposes for patients and the public, for colleagues and students. Furthermore the ability to access information at the point-of-care was considered by registered nurses as valuable to improve patient care because of the wide range of accurate and readily accessible information available via the mobile computing device. The registered nurses in this study felt that being able to access information at the point-of-care increased their confidence and facilitated the provision of quality care because it assisted them in being accurate and sure of what they were doing.

    In this paper, we experimentally investigate the throughput of IEEE 802.11n 2x2 multiple-input-multiple-output (MIMO) signals in a radio-over-fiber-based distributed antenna system (DAS) with different fiber lengths and power imbalance. Both a MIMO-supported access point (AP) and a spatial-diversity-supported AP were separately employed in the experiments. Throughput measurements were carried out with wireless users at different locations in a typical office environment. For the different fiber length effect, the results indicate that MIMO signals can maintain high throughput when the fiber length difference between the two remote antenna units (RAUs) is under 100 m and falls quickly when the length difference is greater. For the spatial diversity signals, high throughput can be maintained even when the difference is 150 m. On the other hand, the separation of the MIMO antennas allows additional freedom in placing the antennas in strategic locations for overall improved system performance, although it may also lead to received power imbalance problems. The results show that the throughput performance drops in specific positions when the received power imbalance is above around 13 dB. Hence, there is a trade-off between the extent of the wireless coverage for moderate bit-rates and the area over which peak bit-rates can be achieved.

    2018-02-01

    Full Text Available Among the strategies to improve public access to justice, increasing the accessibility and comprehensibility of legal information must be ranked as important. In this paper, the authors explore how libraries and librarians might play a role in providing the public with access and guidance to legal information. These issues are considered primarily in the context of two scenarios: that of the self-represented litigant, and that of a party to a limited scope retainer. The authors consider in particular how public libraries as a public space and public librarians as trusted intermediaries might support the objective of greater access. The possible roles of law society/courthouse and academic libraries in training and collection development are also considered. The distinction between providing access to legal information and giving legal advice is discussed briefly, and the authors suggest some possible ways of clarifying this distinction while pursuing the goal of expanding public access to legal information.   Parmi les stratégies susceptibles d’améliorer l’accès du public à la justice, les mesures visant à accroître l’accessibilité et la convivialité de l’information juridique doivent être considérées comme des stratégies importantes. Dans ce document, les auteurs explorent le rôle que peuvent jouer les bibliothèques et les bibliothécaires en orientant le public et en lui donnant accès aux renseignements juridiques. Ce rôle est examiné principalement dans le contexte de deux scénarios : celui de la partie qui se représente elle-même et celui de la partie dont l’avocat a un mandat à portée limitée. Les auteurs se demandent notamment comment les bibliothèques publiques, à titre d’espace public, et les bibliothécaires, à titre d’intermédiaires de confiance, peuvent favoriser l’atteinte de l’objectif d’un meilleur accès à cette information. Les rôles que pourraient être appelées à jouer les

    Since 2005, after a pilot program, the Massachusetts Child Psychiatry Access Project (MCPAP) has provided point-of-care psychiatry expertise and referral assistance by telephone to primary care providers. We examined its adoption and use and the practice characteristics associated with different adoption timelines and use patterns. We merged data on calls to MCPAP in 2005 to 2011 with practice data (enrollment year, panel size, regional team assignment). We categorized practices' days from enrollment to first call (adoption) (0-100, 101-365, > 365 days) and quartile of call frequency (use) (annual highest, middle, and lowest quartiles of number of calls per 1000 empanelled patients). We determined associations between adoption and use and practice characteristics using multivariate models. Among 285 practices, adoption and use varied: 55% called 0 to 100 days from enrollment and 16% called >365 days from enrollment. Practices in the highest quartile of use made a mean 15.5 calls/year per 1000 patients, whereas the lowest quartile made 0.4 calls/year per 1000 patients. Adoption within 100 days was associated with enrollment during or after 2007 (odds ratio [OR] 4.09, 95% confidence interval [CI] 2.23-7.49) and assignment to the team at the pilot site (OR 4.42, 95% CI 2.16-9.04 for central Massachusetts). Highest-quartile use was associated with team assignment (OR 3.58, 95% CI 1.86-6.87 for central Massachusetts) and panel size (OR 0.10, 95% CI 0.03-0.31 for ≥ 10,000 vs < 2000 patients). Adoption and use of MCPAP varied widely. Timing of enrollment, assignment to the team from the program's pilot site, and panel size were associated with patterns of adoption and use. Findings may help other programs design effective implementation strategies. Copyright © 2015 by the American Academy of Pediatrics.

    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

    Full Text Available The accessibility of business reporting, including financial reports on companywebsites is not necessarily increased by providing more information on websites. Thequality of Internet-based information is affected by both the accessibility and quantityof information provided. However, the accessibility of the information is an underresearched area. This paper contributes to the existing body of knowledge on webbasedbusiness reporting, by considering the dimension of accessibility in terms ofwebsite appearance and visual design from four different perspectives. The aim is toconsider the differences that occur in website organisation as a way of considering theaccessibility of information provided on company websites. The paper considers thedifferences in the accessibility of website information between New Zealand andIndian companies as a means of demonstrating the variation that can occur acrosscountries as well as within the same reporting structure. We conclude that Internetfinancial reporting does provide the illusion of comparability but without a moresustained focus on the harmonisation of terminology and attributes included inInternet reporting, the potential for comparison is reduced.

  12. Considerations on private human access to space from an institutional point of view

    Hufenbach, Bernhard

    2013-12-01

    Private human access to space as discussed in this article addresses two market segments: suborbital flight and crew flights to Low Earth Orbit. The role of entrepreneurs, the technical complexity, the customers, the market conditions as well as the time to market in these two segments differ significantly. Space agencies take currently a very different approach towards private human access to space in both segments. Analysing the outcome of broader inter-agency deliberations on the future of human spaceflight and exploration, performed e.g. in the framework of the International Space Exploration Coordination Group, enables to derive some common general views on this topic. Various documents developed by inter-agency working groups recognise the general strategic importance for enabling private human access to space for ensuring a sustainable future of human spaceflight, although the specific definition of private human access and approaches vary. ESA has performed some reflections on this subject throughout the last 5 years. While it gained through these reflections a good understanding on the opportunities and implications resulting from the development of capabilities and markets for Private Human Access, limited concrete activities have been initiated in relation to this topic as of today.

    To evaluate the accessibility to editorial information in Oral & Maxillofacial Surgery journals. A cross-sectional study using the WOS-Web of Science database in three categories: "Surgery," "Otorhinolaryngology," and "Dentistry, Oral Surgery & Medicine" was designed. Journals were filtered by title and classified under three headings: OMFS specialty; OMFS subspecialty and related sciences; and multidisciplinary journals. Specialty scope (OMFS vs. other); impact factor; path for the manuscript; blinding policy; accessibility to reviewers' criteria; and percentage of acceptance. Only 46 of 330 journals met the inclusion criteria. All OMFS journals provided comprehensive information about the review process, compared to 5 of 27 (18.5%) of Oral Surgery and related sciences periodicals. Most specialty journals do not inform about the blind review mode used (20 of 33; 60.6%). Generally, information about the reviewers' assessment criteria is scarce, but is available from all OMFS journals, which also state the percentage of manuscript acceptance (100% vs. 14.8%). OMFS JCR journals provide adequate information about their editorial process in terms of path for the manuscript, accessibility to reviewers' criteria, and percentage of acceptance. Additional efforts are needed to increase accessibility to information about blinding policy and average time from submission to acceptance.

    Mental disorders are widespread and universal. They are frequently accompanied by considerable harmful consequences for the individual and come at a significant economic cost to a community. Yet while effective evidence based prevention and treatment exists, there are a number of barriers to access, implement and disseminate. Cognitive behavior therapy programs, such as those available at www.thiswayup.com.au are widely available using the Internet in high income countries, such as Australia. With the ubiquitous uptake of Internet users globally, it is suggested that low and middle income countries should consider ways to embrace and scale up these cost effective programs. An explanation of why and some suggestions as to how this can be done are presented. Crown Copyright © 2014. Published by Elsevier B.V. All rights reserved.

    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 popularity and usage of social media networks or SNS (social networking sites) among American Internet users age 50 and over doubled between 2009 and 2010 and has steadily climbed. Part of this increased access may be the result of older adults who are living with a chronic disease and are reaching out for online support. Colorectal cancer (CRC) risk is among those concerns, particularly among middle-age and older minority populations where disparities exist. This exploratory study investigates information seeking behavior related to cancer factors (e.g. testing for colon cancer, cancer fatalism) and current social media usage among racial and ethnic minority groups (African American and Latinos) and Whites age 50 and older. The secondary data from the 2012 Health Information National Trends Survey (HINTS) was analyzed to compare these populations. Results show that African Americans and Latinos were only slightly more likely to use social network sites to seek out cancer information compared to Whites. However, Whites were more likely to use the Internet to seek health information compared to African Americans and Latinos. In this sample, Whites were also more likely to be informed by a physician about CRC testing (p social media networks, Internet sites) have increased among older Americans and can serve as critical channels for cancer information and education.

  2. Design of a memory-access controller with 3.71-times-enhanced energy efficiency for Internet-of-Things-oriented nonvolatile microcontroller unit

    2018-04-01

    In realizing a nonvolatile microcontroller unit (MCU) for sensor nodes in Internet-of-Things (IoT) applications, it is important to solve the data-transfer bottleneck between the central processing unit (CPU) and the nonvolatile memory constituting the MCU. As one circuit-oriented approach to solving this problem, we propose a memory access minimization technique for magnetoresistive-random-access-memory (MRAM)-embedded nonvolatile MCUs. In addition to multiplexing and prefetching of memory access, the proposed technique realizes efficient instruction fetch by eliminating redundant memory access while considering the code length of the instruction to be fetched and the transition of the memory address to be accessed. As a result, the performance of the MCU can be improved while relaxing the performance requirement for the embedded MRAM, and compact and low-power implementation can be performed as compared with the conventional cache-based one. Through the evaluation using a system consisting of a general purpose 32-bit CPU and embedded MRAM, it is demonstrated that the proposed technique increases the peak efficiency of the system up to 3.71 times, while a 2.29-fold area reduction is achieved compared with the cache-based one.

  7. Water Quality vs. Sanitation Accessibility: What is the most effective intervention point for preventing cholera in Dhaka, Bangladesh?

    2011-12-01

    Every year, 3 to 5 million individuals contract cholera, an acute diarrheal infection that is caused by the ingestion of food or water containing the Vibrio cholerae bacterium. Because cholera is a waterborne disease, it can be transmitted quickly in environments with inadequate water and sanitation systems where infected waste can easily pollute drinking water. Today, Bangladesh continues to struggle with endemic cholera. Donor organizations address water and sanitation via localized initiatives, including the installation of community water collection sites (i.e. tubewells; water-boiling points; etc.). At this small-scale level, water quality and sanitation accessibility can be improved independently of one another, and when resources are limited, donors must invest in the most effective disease prevention options. This study used laboratory-confirmed cholera incidence data (2000-2009) collected by the International Centre of Diarrheal Disease Research, Bangladesh at their on-site hospital to compare the efficacy of interventions addressing water quality versus sanitation accessibility in Dhaka, Bangladesh. Data regarding use of sanitary latrines and boiling of drinking water were extracted from sequential patient interviews conducted at the Dhaka facility and used as surrogate variables for sanitation accessibility and water quality respectively. Our analysis indicates that boiling water is 10 times more effective at preventing cholera than the use of a sanitary latrine. This finding suggests that regulating water quality is perhaps more critical to cholera prevention than increasing sanitation accessibility in an urban environment like that of Dhaka. At present, WaterAid - one of Bangladesh's most significant water and sanitation donor organizations - invests the majority of its budget on improving sanitation accessibility. The World Health Organization and the United Nations Millennium Development Goals also prioritize sanitation accessibility. However, in

    Full Text Available From its inception in the early 1960s, English for Specific Purposes (ESP has grown to become one of the most prominent areas of EFL teaching. ESP is usually concerned with the teaching of English used in academic studies and/or professional activities, especially the teaching of English related with Business/Economics, Medicine, and Engineering. As the number of courses and students has grown considerably the original team teaching methodology is being substituted by a more autonomous approach in which both ESP instructors and students have to acquire knowledge of the basic concepts of the field by themselves. This new approach lends support to recent developments in the field of learner’s autonomy, especially those based on Internet (for example, Moodle that are being promoted in this era of shortages and lack of resources. Within this framework, this article presents Internet dictionaries, especially the so-called free institutional Internet reference works, as adequate tools for using in cognitive situations, i.e., the social situations that arise when users want to gain knowledge about something. In particular, this article describes five lexicographical structures and functionalities of the BusinessDictionary.com that can be used by ESP instructors and students in order to acquire and/or update their business knowledge.

  9. Neighborhood Socioeconomic Status and Primary Health Care: Usual Points of Access and Temporal Trends in a Major US Urban Area.

    Neighborhood socioeconomic status (SES), an overall marker of neighborhood conditions, may determine residents' access to health care, independently of their own individual characteristics. It remains unclear, however, how the distinct settings where individuals seek care vary by neighborhood SES, particularly in US urban areas. With existing literature being relatively old, revealing how these associations might have changed in recent years is also timely in this US health care reform era. Using data on the Philadelphia region from 2002 to 2012, we performed multilevel analysis to examine the associations of neighborhood SES (measured as census tract median household income) with access to usual sources of primary care (physician offices, community health centers, and hospital outpatient clinics). We found no evidence that residence in a low-income (versus high-income) neighborhood was associated with poorer overall access. However, low-income neighborhood residence was associated with less reliance on physician offices [-4.40 percentage points; 95 % confidence intervals (CI) -5.80, -3.00] and greater reliance on the safety net provided by health centers [2.08; 95 % CI 1.42, 2.75] and outpatient clinics [1.61; 95 % CI 0.97, 2.26]. These patterns largely persisted over the 10 years investigated. These findings suggest that safety-net providers have continued to play an important role in ensuring access to primary care in urban, low-income communities, further underscoring the importance of supporting a strong safety net to ensure equitable access to care regardless of place of residence.

    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.

    In the era of informed patient decision-making, educated patients are vital contributors. The Internet provides a vast information source that patients will access. It is imperative that this information be relevant and understandable. Various treatments, each with advantages and disadvantages, are available. We sought to examine the standard of information about the diagnosis and management of rotator cuff tears available to patients on the Internet. We identified 125 websites from searching "rotator cuff tear" in the 5 most popular Internet search engines. The websites were examined for readability by measuring the Flesch Reading Ease Score, the Flesch-Kincaid Grade Level, and the Gunning Fog Index. The quality of the websites was measured by the DISCERN instrument, the Journal of the American Medical Association benchmark criteria, and Health on the Net Foundation certification. There were 59 individual URLs analyzed. Overall, the quality was poor, with the average DISCERN score being only 39.47. Furthermore, the mean reading grade level was above 9 (recommended level, 6). Health on the Net Foundation certification did correspond to significantly worse readability scores (P = .004) but did not correlate with improved DISCERN scores. Those that satisfied more of the Journal of the American Medical Association benchmark criteria had significantly better DISCERN scores (P < .001). Information about rotator cuff tears is of a low standard and is in many cases written at too high a level for the general population. There are instruments of which we, as surgeons, must be aware to evaluate the resources available and to recommend them to patients to ensure that they understand their condition and treatment options.

  16. Adaptive interference-aware multichannel assignment for shared overloaded small-cell access points under limited feedback

    KAUST Repository

    Radaydeh, Redha Mahmoud

    2014-02-01

    This paper proposes a reduced-complexity multichannel assignment scheme for short-range cellular systems. It treats the scenario when a number of small-cell (e.g., femtocell) access points (APs) can be shared to serve active scheduled users. The APs employ isotropic antenna arrays and operate using an open-access control strategy. To improve the reuse ratio of physical resources, the APs are assumed to occupy a single physical channel, wherein coordination among them is infeasible. On the other hand, to improve the spatial coverage, a scheduled user can be served by a single transmit channel from an AP at a time. For the case of overloaded APs and when the feedback links are capacity limited, the scheme attempts to identify the suitable transmit channels from the deployed APs in an adaptive manner such that certain performance and/or processing load limits are satisfied. The effects of some system and design parameters on the outcomes of the scheme are thoroughly discussed. Novel results for the statistics of the resulting interference power are presented, from which results for some performance measures and processing loads are obtained. Numerical and simulations results are provided to clarify the achieved gains, as compared with related models under different operating conditions. © 2013 IEEE.

    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.

    Full Text Available Infrastructure-based wireless LAN technology has been widely used in today's personal communication environment. Power efficiency and battery management have been the center of attention in the design of handheld devices with wireless LAN capability. In this paper, a hybrid protocol named improved PCF operation is proposed, which intelligently chooses the access point- (AP- assisted DCF (distributed coordinator function and enhanced PCF (point coordinator function transmission mechanism of IEEE 802.11 protocol in an infrastructure-based wireless LAN environment. Received signal strength indicator (RSSI is used to determine the tradeoff between direct mobile-to-mobile transmission and transmission routed by AP. Based on the estimation, mobile stations can efficiently communicate directly instead of being routed through AP if they are in the vicinity of each other. Furthermore, a smart AP protocol is proposed as extension to the improved PCF operation by utilizing the historical end-to-end delay information to decide the waking up time of mobile stations. Simulation results show that using the proposed protocol, energy consumption of mobile devices can be reduced at the cost of slightly longer end-to-end packet delay compared to traditional IEEE 802.11 PCF protocol. However, in a non-time-critical environment, this option can significantly prolong the operation time of mobile devices.

    Full Text Available This paper studies backhaul bandwidth aggregation in the context of a wireless local area network composed of two different types of access points: those with spare backhaul capacity (which we term providers and those in shortage of it (beneficiaries; the aim is to transfer excess capacity from providers to beneficiaries. We model the system as a matching game with many-to-one setting wherein several providers can be matched to one beneficiary and adopt the so-called deferred acceptance algorithm to reach an optimal and stable solution. We consider two flavors, when the beneficiaries are limited in their resource demands and when they are not, and two scenarios, when resources are abundant and when they are scarce. Our results show that the many-to-one setting outperforms the one-to-one case in terms of overall throughput gain, resource usage, and individual beneficiaries satisfaction by up to 50%, whether resources are scarce or abundant. As of the limited versus nonlimited case, the former ensures more fair sharing of spectral resources and higher satisfaction percentage between beneficiaries.

The Gateway provides a set of visualization and data analysis tools including: HTML5-based interactive visualization of high-level data products from all instrument teams in the form of: line plots, orbital content plots, dynamical energy spectra, L-shell context plots (including two-spacecraft plotting), FFT spectra of wave data, solar wind and geomagnetic indices data, etc.; download custom multi-instrument CDF data files of selected data products; publication quality plots of digital data; combined orbit predicts for mission planning and coordination including: Van Allen Probes, MMS, THEMIS, Arase (ERG), Cluster, GOES, Geotail, FIREBIRD; magnetic footpoint calculator for coordination with LEO and ground-based assets; real-time computation and processing of empirical magnetic field models - computation of magnetic ephemeris, computation of adiabatic invariants. Van Allen Probes is the first spacecraft mission to provide a nowcast of the radiation environment in the heart of the radiation belts, where the radiation levels are the highest and most dangerous for spacecraft operations. For this purpose, all instruments continuously broadcast a subset of their science data in real time. Van Allen Probes partners with four foreign institutions who operate ground stations that receive the broadcast: Korea (KASI), the Czech republic (CAS), Argentina (CONAE), and Brazil (INPE). The SpWx broadcast is then collected at APL and delivered to the community via the Science Gateway.

    Objectives: To assess the uptake, usage and acceptability of TOXBASE, the National Poisons Information Service internet toxicology information service. Methods: An observational study of database usage, and a questionnaire of users were undertaken involving users of TOXBASE within the UK between August 1999, when the internet site was launched, and May 2000. The main outcome measures were numbers of registered users, usage patterns on the database, responses to user satisfaction questionnaire. Results: The number of registered users increased from 567 to 1500. There was a 68% increase in accident and emergency departments registered, a 159% increase in general practitioners, but a 324% increase in other hospital departments. Between January 2000 and the end of May there had been 60 281 accesses to the product database, the most frequent to the paracetamol entry (7291 accesses). Ecstasy was the seventh most frequent entry accessed. Altogether 165 of 330 questionnaires were returned. The majority came from accident and emergency departments, the major users of the system. Users were generally well (>95%) satisfied with ease and speed of access. A number of suggestions for improvements were put forward. Conclusions: TOXBASE has been extensively accessed since being placed on the internet (http://www.spib.axl.co.uk). The pattern of enquiries mirrors clinical presentation with poisoning. The system seems to be easily used. It is a model for future delivery of treatment guidelines at the point of patient care. PMID:11777868

    To more closely assess medication errors in gout care, we examined data from a national, Internet-accessible error reporting program over a 5-year reporting period. We examined data from the MEDMARX database, covering the period from January 1, 1999 through December 31, 2003. For allopurinol and colchicine, we examined error severity, source, type, contributing factors, and healthcare personnel involved in errors, and we detailed errors resulting in patient harm. Causes of error and the frequency of other error characteristics were compared for gout medications versus other musculoskeletal treatments using the chi-square statistic. Gout medication errors occurred in 39% (n = 273) of facilities participating in the MEDMARX program. Reported errors were predominantly from the inpatient hospital setting and related to the use of allopurinol (n = 524), followed by colchicine (n = 315), probenecid (n = 50), and sulfinpyrazone (n = 2). Compared to errors involving other musculoskeletal treatments, allopurinol and colchicine errors were more often ascribed to problems with physician prescribing (7% for other therapies versus 23-39% for allopurinol and colchicine, p < 0.0001) and less often due to problems with drug administration or nursing error (50% vs 23-27%, p < 0.0001). Our results suggest that inappropriate prescribing practices are characteristic of errors occurring with the use of allopurinol and colchicine. Physician prescribing practices are a potential target for quality improvement interventions in gout care.

    2000-12-01

    This paper describes the informational and treatment opportunities offered by the Worldwide Web (WWW) and comments on the advantages, disadvantages and potential dangers of its role in mental health and mental health research. Two perspectives are taken: (i) the impact of the Web from the point of view of the clinician (the practitioner view) and (ii) the impact of the Web on the public's knowledge of mental health (mental health literacy; the community or public health view). These perspectives are applied to two areas of impact: (i) information and knowledge; and (ii) treatment and self-help. The Web, due to its accessibility, has advantages in providing access to information, online therapy and adjunctive therapy in mental health. Problems include information overload, poor information quality, potential harm and lack of scientific evaluation. Issues of overload and quality of information, the potential for harm and the need to evaluate interventions are not unique to the Internet. However, the Internet has special features which make these issues more prominent. The Internet is likely to increase the general public's access to information and to decrease unmet need. Sites and interventions on the Internet need to be formally evaluated.

    Full Text Available Access to point-of-care (POC diagnostics services is essential for ensuring rapid disease diagnosis, management, control, and surveillance. POC testing services can improve access to healthcare especially where healthcare infrastructure is weak and access to quality and timely medical care is a challenge. Improving the accessibility and efficiency of POC diagnostics services, particularly in resource-limited settings, may be a promising route to improving healthcare outcomes. In this review, the accessibility of POC testing is defined as the distance/proximity to the nearest healthcare facility for POC diagnostics service. This review provides an overview of the impact of POC diagnostics on healthcare outcomes in low- and middle-income countries (LMICs and factors contributing to the accessibility of POC testing services in LMICs, focusing on characteristics of the supply chain management and quality systems management, characteristics of the geographical location, health infrastructure, and an enabling policy framework for POC diagnostics services. Barriers and challenges related to the accessibility of POC diagnostics in LMICs were also discussed. Bearing in mind the reported barriers and challenges as well as the disease epidemiology in LMICs, we propose a lean and agile supply chain management framework for improving the accessibility and efficiency of POC diagnostics services in these settings.

    Lukose, Rajan Mathew

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

    Poland, M. P.; Teasdale, R.; Kraft, K.

    2010-12-01

    Internet-accessible real- and near-real-time Earth science datasets are an important resource for geoscience education, but relatively few comprehensive datasets are available, and background information to aid interpretation is often lacking. In response to this need, the U.S. Geological Survey’s (USGS) Hawaiian Volcano Observatory, in collaboration with the National Aeronautics and Space Administration and the University of Hawai‘i, Mānoa, established the Volcanoes Exploration Project: Pu‘u ‘O‘o (VEPP). The VEPP Web site provides access, in near-real time, to geodetic, seismic, and geologic data from the Pu‘u ‘O‘o eruptive vent on Kilauea Volcano, Hawai‘i. On the VEPP Web site, a time series query tool provides a means of interacting with continuous geophysical data. In addition, results from episodic kinematic GPS campaigns and lava flow field maps are posted as data are collected, and archived Webcam images from Pu‘u ‘O‘o crater are available as a tool for examining visual changes in volcanic activity over time. A variety of background information on volcano surveillance and the history of the 1983-present Pu‘u ‘O‘o-Kupaianaha eruption puts the available monitoring data in context. The primary goal of the VEPP Web site is to take advantage of high visibility monitoring data that are seldom suitably well-organized to constitute an established educational resource. In doing so, the VEPP project provides a geoscience education resource that demonstrates the dynamic nature of volcanoes and promotes excitement about the process of scientific discovery through hands-on learning. To support use of the VEPP Web site, a week-long workshop was held at Kilauea Volcano in July 2010, which included 25 participants from the United States and Canada. The participants represented a diverse cross-section of higher learning, from community colleges to research universities, and included faculty who teach both large introductory non-major classes

  3. Potential and Limitations of the Internet Use in Learning Process

    Directory of Open Access Journals (Sweden)

    D. Pavlovic

    2017-12-01

    Full Text Available The main research objective of this paper is to point out potentials and limitations of the Internet in the process of learning in higher education, through review and analysis of literature. The results of this theoretical study emphasize positive aspects of the Internet use in the learning process of university students that arise from the Internet features such as high technical capabilities, power, speed, universality and accessibility, as well as high sensitivity of young people to the means of new media. The positive effects of the applica-tion of the Internet were pointed out in research studies that analysed the pro-cess of innovation in higher education, the changes in the culture of learning, or certain aspects of personality development of university students. In contrast, some studies pointed out the limitations that may occur when using the Internet in the learning process related primarily to the credibility of the infor-mation, light and entertaining content dominance, and dependence on technology. Accordingly, it is recommended to adopt the measures on a larger scale that will affect the greater use of the Internet in the process of acquiring knowledge, especially in the field of higher education.

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

    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.

    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

  16. Ultrasound-guided antegrade access during laparoscopic pyeloplasty in infants less than one year of age: A point of technique

    Directory of Open Access Journals (Sweden)

    Arvind Ganpule

    2012-01-01

    Full Text Available Background: Access to urethras and ureters of infants may be hazardous and injurious through an endoscopic route. Placement and removal of stents in infants requires anaesthesia and access through these small caliber urethras. We describe our technique of placing antegrade splint during a laparoscopic pyeloplasty in these infants. Materials and Methods: An ultrasound-guided percutaneous renal access is obtained. Telescopic metal two part needle is passed into the kidney over a guide wire. A second guide wire is passed through the telescopic metal two part needle. The tract is dilated with 14 Fr screw dilator. Over one guide wire, a 5 Fr ureteric catheter is passed and coiled in the renal pelvis. Over the other wire, a 14 Fr malecot catheter is placed as nephrostomy. Laparoscopic pyeloplasty is then done. During pyelotomy, the ureteric catheter is pulled and advanced through the ureter before the pyeloplasty is completed. The ureteric catheter thus acts as a splint across the anastomosis. Ureteric catheter is removed on the 3 rd post operative day and nephrostomy is clamped. Nephrostomy is removed on 4 th post operative day if child is asymptomatic. The modified technique was successfully done in five patients aged less than one year old. All patients tolerated the procedure well. Post operative period was uneventful in all. Conclusion: Ultrasound-guided ante grade nephroureteral ureteral splint for infant laparoscopic pyeloplasty is safe. It avoids the need for urethral instrumentation for insertion and removal of stents in these small patients.

    To document the extent of access block and ED overcrowding in New Zealand in 2010 and to determine whether these were linked to the hospital's ability to meet the Shorter Stays in ED target. Surveys of all New Zealand EDs were undertaken at two points in time in 2010 to determine ED occupancy. Data on target achievement during corresponding time periods were obtained from the Ministry of Health. In tertiary and secondary hospitals, respectively, access block was seen in 64% versus 23% (P= 0.05) and overcrowding was seen in 57.1% versus 39% (P= 0.45). No hospital with access block met the 'Shorter Stays' target, compared with 60% without access block (P= 0.001). Twenty-three per cent of hospitals with ED overcrowding met the target compared with 43% without ED overcrowding (P= 0.42). The number of patients experiencing ≥8 h delay to admission were 25 in May and 59 in August (P= 0.04). This represented 45.5% and 79.7% of patients waiting for admission, respectively (P= 0.08). Hospital access block was seen more often in larger hospitals and significantly associated with failure to meet the 'Shorter Stays in ED' health target, whereas ED overcrowding was seen in both small and large hospitals, but not associated with failure to meet the target. © 2011 The Authors.

    Full Text Available 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 behavior. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction.

    Full Text Available Nowadays, Internet banking is a service provided by all Romanian banks which has become a daily need for millions of users. This study contains a brief overview of the Internet banking services usage level in the European Union for the period 2007-2016. An increasing in the use of Internet banking services in the EU can be observed at the level of the analysed period. At the same time we compared the users (individuals aged 16 to 74 of Internet banking services to other European countries and we found that the users of the Internet banking services in Romania are still far below the European average but the trend is an upward one. In this study we have focused our attention only on Internet banking, as it is the most commonly used payment instrument in the Romanian practice of remote access payment instruments. The indicators considered in this study were the Internet banking users and the Internet users. We have used the model of the simple linear regression to highlight the existence of a relationship between the variables. In this respect we used statistical data taken from Eurostat and Romanian Ministry of Communications and Information Society as well as data provided by the Romanian National Institute of Statistics for the period 2009-2014. The results of the model have pointed out the fact that the rise of the number of Internet users leads to an increase of the number of Internet banking users.

    1995-01-01

    The Internet promises to be an essential resource for radiology administrators. In addition to offering remarkable access to colleagues all over the world, the Internet offers specialized information resources for radiology, many of which are described in this article. The Internet is many networks that communicate with each other and whose general purpose is to share information. Although there are several consortium organizations that support and regulate it, no single body or organization "owns" the Internet. Many employees and students at large teaching centers already have access to the Internet through their institution's connection. Individuals and small institutions can contract with independent service providers for Internet access. Internet functions covered in this article include: e-mail, listservs, newsgroups, file transfer protocols, Gopher, and the World Wide Web. The rapid pace of information exchange is making the world of radiology smaller and more intimate. Communication and knowledge are becoming so accessible that individuals are privy to the most minute happenings in the industry. Sharing information on the Internet will benefit not only individual users and the industry, but also patients.

    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.

    OBJECTIVES To determine whether minors can successfully purchase alcohol online and to examine age verification procedures at the points of order and delivery. DESIGN A cross-sectional study evaluated underage alcohol purchase attempts from 100 popular Internet vendors. SETTING The study was conducted at the University of North Carolina at Chapel Hill, July 14-27, 2011. PARTICIPANTS Eight 18- to 20-year-old individuals participated. OUTCOME MEASURES Rates of successful sales to minors and use of age verification procedures at order and delivery were determined. RESULTS Of the 100 orders placed by the underage buyers, 45% were successfully received; 28% were rejected as the result of age verification. Most vendors (59%) used weak, if any, age verification at the point of order, and, of 45 successful orders, 23 (51%) used none. Age verification at delivery was inconsistently conducted and, when attempted, failed about half of the time. CONCLUSIONS Age verification procedures used by Internet alcohol vendors do not adequately prevent online sales to minors. Shipping companies should work with their staff to improve administration of age verification at delivery, and vendors should use rigorous age verification at order and delivery. Further research should determine the proportion of minors who buy alcohol online and test purchases from more vendors to inform enforcement of existing policies and creation of new policies to reduce youth access to alcohol online.

    Point-of-use water chlorination reduces diarrhoea risk by 25-85%. Social marketing has expanded access to inexpensive sodium hypochlorite for water treatment, at a cost of less than US$0.01 per day, in Kenya. To increase product access, women's groups in western Kenya were trained to educate neighbours and sell health products to generate income. We evaluated this programme's impact on equity of access to water treatment products in a cross-sectional survey. We surveyed 487 randomly selected households in eight communities served by the women's groups. Overall, 20% (range 5-39%) of households in eight communities purchased and used chlorine, as confirmed by residual chlorine observed in stored water. Multivariate models using illiteracy and the poorest socioeconomic status as a referent showed that persons with at least some primary education (OR 2.5, 95% CI 1.8, 3.5) or secondary education (OR 5.4, 95% CI 1.6, 17.5) and persons in the four wealthiest quintiles (OR 2.5, 95% CI 1.0, 6.0) were more likely to chlorinate stored water. While this implementation model was associated with good product penetration and use, barriers to access to inexpensive water treatment remained among the very poor and less educated.

    Full Text Available The possibilities offered by the use of the Internet increasingly intensify the problem of Internet addiction, which has become more prevalent in the last decade, marked by the growing availability of mobile devices and new media and their exacerbation of the problem. Research on Internet addiction, initiated by Kimberly Young at the end of the twentieth century, usually appears in the literature in the context of young people who have been found to be most vulnerable. The phenomenon is known as Adolescent Internet Addiction. Compulsive use of the Internet is a complex phenomenon, its effects being visible in almost all aspects of a young person’s social life. It is manifested in a variety of pathological behaviors and emotional states grouped into several major psycho-physical and social effects that may appear simultaneously, e.g. anger, depression, loneliness or anxiety associated with the lack of access to the network, the weakening of social ties, withdrawal from real life, lack of educational achievement, chronic fatigue or deteriorating health. The authors of this study aim to assess the level of Internet addiction among adolescents in Poland and indicate its main behavioral manifestations, in the students surveyed, which influence their pathological use of the Internet. Our study involved a total of 505 students from three high schools located in Rzeszow (N = 505 and was carried out by questionnaires, including, among others, The Problematic Use of the Internet (PUI which is the Polish adaptation of Kimberly Young’s Internet Addiction Test (IAT (Cronbach’s α = 0.89. Statistical analysis of responses from the PUI test allowed us to determine (1 the level of Internet addiction among these adolescents, whereas the univariate (ANOVA analysis enabled us (2 to verify the hypothesis of the existence of differences in the level of Internet addiction among the investigated groups as far as gender, place of residence or grade are concerned

    2014-01-01

    An innovative wavelength division multiplex-radio over fiber-passive optical network architecture for multiple access points (AP) based on multitone generation and triple sextupling frequency is proposed and demonstrated. A dual-drive Mach-Zehnder modulator (DD-MZM) is utilized to realize the multitone generation. Even sidebands are suppressed to make the adjacent frequency separation twice the frequency of the local oscillator by adjusting the modulation voltage of the DD-MZM. Due to adopting three fiber Bragg gratings to reflect the unmodulated sidebands for uplink communications source free at optical network unit (ONU), is achieved. The system can support at least three APs at one ONU simultaneously with a 30 km single-mode fiber (SMF) transmission and 5 Gb/s data rate both for uplink and downlink communications. The theoretical analysis and simulation results show the architecture has an excellent performance and will be a promising candidate in future hybrid access networks.

    Today the Internet plays a role in the lives of nearly 40% of the world's population, and it is becoming increasingly entwined in daily life. This growing presence is transforming psychological science in terms of the topics studied and the methods used. We provide an overview of the literature, considering three broad domains of research: translational (implementing traditional methods online; e.g., surveys), phenomenological (topics spawned or mediated by the Internet; e.g., cyberbullying), and novel (new ways to study existing topics; e.g., rumors). We discuss issues (e.g., sampling, ethics) that arise when doing research online and point to emerging opportunities (e.g., smartphone sensing). Psychological research on the Internet comes with new challenges, but the opportunities far outweigh the costs. By integrating the Internet, psychological research has the ability to reach large, diverse samples and collect data on actual behaviors, which will ultimately increase the impact of psychological research on society.

    There are many and varied ways of connecting to the Internet. For the vast majority of the Internet's existence, most people connected using the maddeningly slow click-and-wait experience of a dial-up connection. By June 2005, the number of the newer and faster broadband connections in the UK exceeded dial-up connections for the first time (approximately 1/3 broadband cable and 2/3 broadband ADSL). By the middle of 2006, 40% of households in the UK had a broadband connection, compared to just 28% in 2005. In the last quarter of 2006, the total number of broadband subscriptions in the UK had topped the 13 million mark (one subscriber may equate to multiple users sharing one connection). Mobile Internet access via mobile phones and other devices will mark the biggest change in the way that we access the Internet and is likely to have a profound effect on our everyday lives. In this section, we look at the various ways of connecting to the Internet and compare the features, benefits and costs of each.

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

    Lehr, William H.; Pupillo, Lorenzo Maria

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

    Research suggests that Internet-based gambling includes risk factors that may increase gambling problems. The current study aimed to investigate subgroups of gamblers to identify the potential harms associated with various forms and modes of gambling. An online survey was completed by 4,594 respondents identified as Internet-only (IG), land-based only (LBGs), or mixed-mode (MMG) gamblers based on self-reported gambling behaviour in the last 12months. Results showed significant socio-demographic differences between groups, with the LBGs being the oldest and MMGs the youngest. MMGs engaged in the greatest variety of gambling forms, had the highest average problem gambling severity scores, and were more likely to attribute problems to sports betting than the other groups. IGs were involved in the lowest number of divergent gambling activities, most likely to gamble frequently on sports and races, and attribute problems to these forms. Compared to the other groups, LBs had a higher proportion of problem gamblers than IGs and were most likely to play electronic gaming machines weekly, with this form of gambling contributing to problems at a substantially greater rate. This study confirms the importance of considering gambling involvement across subgroups of Internet or land-based gamblers. There is a need to consider the interaction between forms and modes of gambling to advance our understanding of the potential risk of mode of gambling to contribute to problems.

    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.

    never realize its academic potential. The Internet has become a useful and valuable academic tool where it connects users to an information source of previously established quality, as, for example, in the case of Chemical Abstracts On Line. The processes that establish the quality of the information in the printed version of CA are the same as those for the on-line version; indeed, the printed version is the same as the on-line version, but electronic access provides a variety of potential advantages that include on demand access as well as multiple accesses. All of this, of course, comes at a cost which some have not figured out how to bear. The point of the CA analogy is that the quality of the on-line material is assured because there is no difference between the information in the electronic and the printed version. How can telecommunications technologies be used to enhance, for example, this Journal. We clearly can't afford to "give away" the contents of the Journal on the Internet although this is technologically feasible. An exact representation of each page of the Journal could be made available in electronic form to be delivered to a local laser printer--but to what end? We could attempt to sell electronic subscriptions, but our estimate is that these would be more expensive than the equivalent print version of the Journal. Moreover, many of our current readers could not access, or possibly would not be interested in, an exact electronic representation. So we have chosen to augment the print Journal with an electronic addition that will permit us to provide an expanded service to those who have access to the Internet. For example, we can provide supplementary tables of data, student handouts, full-size templates for models, color versions of illustrations that our print budget dictates be printed in black and white, and eventually, video clips of demonstrations and experiments. Our electronic augmentation begins with this issue--at our new Web site at http

    The lack of safe water creates a tremendous burden of diarrheal disease and other debilitating, life-threatening illnesses for people in the developing world. Point-of-use (POU) water treatment technology has emerged as an approach that empowers people and communities without access to safe water to improve water quality by treating it in the home. Several POU technologies are available, but, except for boiling, none have achieved sustained, large-scale use. Sustained use is essential if household water treatment technology (HWT) is to provide continued protection, but it is difficult to achieve. The most effective, widely promoted and used POU HWTs are critically examined according to specified criteria for performance and sustainability. Ceramic and biosand household water filters are identified as most effective according to the evaluation criteria applied and as having the greatest potential to become widely used and sustainable for improving household water quality to reduce waterborne disease and death.

  19. Cost- and reliability-oriented aggregation point association in long-term evolution and passive optical network hybrid access infrastructure for smart grid neighborhood area network

    With the rapid development of the smart grid, the data aggregation point (AP) in the neighborhood area network (NAN) is becoming increasingly important for forwarding the information between the home area network and wide area network. Due to limited budget, it is unable to use one-single access technology to meet the ongoing requirements on AP coverage. This paper first introduces the wired and wireless hybrid access network with the integration of long-term evolution (LTE) and passive optical network (PON) system for NAN, which allows a good trade-off among cost, flexibility, and reliability. Then, based on the already existing wireless LTE network, an AP association optimization model is proposed to make the PON serve as many APs as possible, considering both the economic efficiency and network reliability. Moreover, since the features of the constraints and variables of this NP-hard problem, a hybrid intelligent optimization algorithm is proposed, which is achieved by the mixture of the genetic, ant colony and dynamic greedy algorithm. By comparing with other published methods, simulation results verify the performance of the proposed method in improving the AP coverage and the performance of the proposed algorithm in terms of convergence.

    The aim of this study was to evaluate the Internet use of a group of lumbar disc surgery candidates in order to determine the rate of Internet search by the patients on their disorders and more importantly the reliability of the accessed websites. Fifty patients who were scheduled for lumbar disc surgery were divided into 2 groups, namely patients who accepted the surgery at the first offer and those who wanted to think over. Educational level information was obtained and patients were asked whether they had searched their disorder and offered surgery on the Internet. Then, a questionnaire was administered and the reliability of the websites was evaluated. Correction: The first 30 websites on the first 3 pages of Google ® search engine, the most commonly used search engine in Turkey, were evaluated with the DISCERN ® instrument. Of 50 patients, 33 (66%) had conducted a search for the surgery on the Internet. All university graduates, 88.2% of high school graduates, and 18.7% of primary-secondary school graduates had conducted an Internet search. The quality and reliability of the information was high (4.5 points) for 2 (7.1%) websites, moderate (2.3 points) for 6 websites (21.4%) and poor (1 point) for 20 websites (71.4%) as scored with the DISCERN ® instrument. The mean DISCERN ® score of was 1.1 for websites of health-related institutions or healthcare news, 2.75 for personal websites of physicians and 2.5 for personal websites of non-physicians. The mean DISCERN ® score of all websites was 1.5. Most of the patients undergoing lumbar disc surgery at our clinic had searched information about the surgical procedure on the Internet. We found that 92.9% of the websites evaluated with the DISCERN ® instrument had inadequate information, suggesting low-level reliability. Copyright © 2017 Elsevier B.V. All rights reserved.

    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...

    Point-of-care (POC) testing has been shown to help improve healthcare access in resource-limited settings. However, there is paucity of evidence on accessibility of POC testing for prevention of mother-to-child transmission (PMTCT) in resource-limited settings. We propose to conduct a systematic scoping review to map the evidence on POC testing services for PMTCT. A scoping review framework, proposed by Arksey and O'Malley, will guide the study. A comprehensive literature search will be performed in the following electronic databases: PubMed, Science Direct, Cochrane Central, Google Scholar and databases within EBSCOhost (Medline and CINAHL). The primary research articles published in peer-reviewed journals and grey articles addressing our question will be included. One reviewer will conduct title screening and the results will be exported to endnote library. Two independent reviewers will perform abstract, then full article screening in parallel. The same process shall be employed to extract data from eligible studies. Data analysis will involve a narrative summary of included studies and thematic content analysis aided by NVIVO software V.11. The mixed methods assessment tool will be used to assess the quality of studies that will be included. Ethical approval is not applicable to this study. The study findings will be disseminated through publication in a peer-reviewed journal and presentations at conferences related to syphilis, HIV, PMTCT, bacterial infections and POC diagnostics.

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

    2018-04-01

    In this paper, from the viewpoint of cell size and sensing margin, the impact of a novel cross-point-type one transistor and one magnetic tunnel junction (1T–1MTJ) spin-transfer-torque magnetoresistive random access memory (STT-MRAM) cell with a multi-pillar vertical body channel (BC) MOSFET is shown for high density and wide sensing margin STT-MRAM, with a 10 ns writing period and 1.2 V V DD. For that purpose, all combinations of n/p-type MOSFETs and bottom/top-pin MTJs are compared, where the diameter of MTJ (D MTJ) is scaled down from 55 to 15 nm and the tunnel magnetoresistance (TMR) ratio is increased from 100 to 200%. The results show that, benefiting from the proposed STT-MRAM cell with no back bias effect, the MTJ with a high TMR ratio (200%) can be used in the design of smaller STT-MRAM cells (over 72.6% cell size reduction), which is a difficult task for conventional planar MOSFET based design.

  1. A Seamless Handoff Scheme with Access Point Load Balance for Real-Time Services Support in 802.11 Wireless LANs

    Science.gov (United States)

    Manodham, Thavisak; Loyola, Luis; Miki, Tetsuya

    IEEE 802.11 wirelesses LANs (WLANs) have been rapidly deployed in enterprises, public areas, and households. Voice-over-IP (VoIP) and similar applications are now commonly used in mobile devices over wireless networks. Recent works have improved the quality of service (QoS) offering higher data rates to support various kinds of real-time applications. However, besides the need for higher data rates, seamless handoff and load balancing among APs are key issues that must be addressed in order to continue supporting real-time services across wireless LANs and providing fair services to all users. In this paper, we introduce a novel access point (AP) with two transceivers that improves network efficiency by supporting seamless handoff and traffic load balancing in a wireless network. In our proposed scheme, the novel AP uses the second transceiver to scan and find neighboring STAs in the transmission range and then sends the results to neighboring APs, which compare and analyze whether or not the STA should perform a handoff. The initial results from our simulations show that the novel AP module is more effective than the conventional scheme and a related work in terms of providing a handoff process with low latency and sharing traffic load with neighbor APs.

    of these, all trial participants were provided with nicotine replacement therapy (NRT). Three other trials in adults did not detect significant long term effects. One of these provided access to a website as an adjunct to counselling and bupropion, one compared web-based counselling, proactive telephone-based counselling or a combination of the two as an adjunct to varenicline. The third only provided a list of Internet resources. One further short-term trial did show a significant increase in quit rates at 3 months. A trial in college students increased point prevalence abstinence after 30 weeks but had no effect on sustained abstinence. Two small trials in adolescents did not detect an effect on cessation compared to control, whilst a third small trial did detect a benefit of a web-based adjunct to a group programme amongst adolescents.Ten trials, all in adult populations, compared different Internet sites or programmes. There was some evidence that sites that were tailored and interactive might be more effective than static sites, but this was not detected in all the trials that explored this factor. One large trial did not detect differences between different Internet sites. One trial of a tailored intervention as an adjunct to NRT use showed a significant benefit but only had a 3-month follow up. One trial detected evidence of a benefit from tailored email letter compared to a non-tailored one. Trials failed to detect a benefit of including a mood management component (three trials), or an asynchronous bulletin board. Higher abstinence rates were typically reported by participants who actively engaged with the programme (as reflected by the number of log-ins). Results suggest that some Internet-based interventions can assist smoking cessation, especially if the information is appropriately tailored to the users and frequent automated contacts with the users are ensured, however trials did not show consistent effects.

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

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.

    Busy diagnosticians need to know what is useful, and what is dross, when dealing with the internet. From the comprehensive array of resources that characterizes the offerings available via the world wide web and email correspondence, in particular, this chapter seeks to identify the most useful tools for the diagnostics laboratory. With rapid communications and fast internet consultations only a few keystrokes away, there really is no point in wasting time on fruitless searches when professionals are so accessible. But accessibility carries the weight of responsibility as well, and communications must be engaged with a fair modicum of civility and common courtesy. Responsibility is a crucially important component of public or semiprivate communication in terms of your own identity, and that of the organization that you represent. Recognition of the relative vulnerability of individual machines to the worldwide disseminated computer viruses, worms, or trojan horses currently abounding, for example, is perhaps the most important step in your approach to security issues, but this recognition must go hand in hand with institutional steps to protect the organization of which you are a part. Organizational tools that serve the diagnostician well in the laboratory can also be mobilized in the aid of communications through the net, and always that harbinger of understanding, common sense, should prevail in one's dealings both with machines, and the people who are communicating either directly or indirectly through them.

    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.

    BACKGROUND: Universal access to health care is valued in Canada but increasing wait times for services (eg, cardiology consultation) raise safety questions. Observations suggest that deficiencies in the process of care contribute to wait times. Consequently, an outpatient clinic was designed for Ensuring Access and Speedy Evaluation (Cardiac EASE) in a university group practice, providing cardiac consultative services for northern Alberta. Cardiac EASE has two components: a single-point-of-entry intake service (prospective testing using physician-approved algorithms and previsit triage) and a multidisciplinary clinic (staffed by cardiologists, nurse practitioners and doctoral-trained pharmacists). OBJECTIVES: It was hypothesized that Cardiac EASE would reduce the time to initial consultation and a definitive diagnosis, and also increase the referral capacity. METHODS: The primary and secondary outcomes were time from referral to initial consultation, and time to achieve a definitive diagnosis and management plan, respectively. A conventionally managed historical control group (three-month pre-EASE period in 2003) was compared with the EASE group (2004 to 2006). The conventional referral mechanism continued concurrently with EASE. RESULTS: A comparison between pre-EASE (n=311) and EASE (n=3096) revealed no difference in the mean (± SD) age (60±16 years), sex (55% and 52% men, respectively) or reason for referral, including chest pain (31% and 40%, respectively) and arrhythmia (27% and 29%, respectively). Cardiac EASE reduced the time to initial cardiac consultation (from 71±45 days to 33±19 days) and time to a definitive diagnosis (from 120±86 days to 51±58 days) (P<0.0001). The annual number of new referrals increased from 1512 in 2002 to 2574 in 2006 due to growth in the Cardiac EASE clinic.

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

    Innovative research in childhood rheumatic diseases mandates international collaborations. However, researchers struggle with significant regulatory heterogeneity; an enabling European Union (EU)-wide framework is missing. The aims of the study were to systematically review the evidence for best practice and to establish recommendations for collaborative research. The Paediatric Rheumatology European Single Hub and Access point for paediatric Rheumatology in Europe (SHARE) project enabled a scoping review and expert discussion, which then informed the systematic literature review. Published evidence was synthesised; recommendations were drafted. An iterative review process and consultations with Ethics Committees and European experts for ethical and legal aspects of paediatric research refined the recommendations. SHARE experts and patient representatives vetted the proposed recommendations at a consensus meeting using Nominal Group Technique. Agreement of 80% was mandatory for inclusion. The systematic literature review returned 1319 records. A total of 223 full-text publications plus 22 international normative documents were reviewed; 85 publications and 16 normative documents were included. A total of 21 recommendations were established including general principles (1-3), ethics (4-7), paediatric principles (8 and 9), consent to paediatric research (10-14), paediatric databank and biobank (15 and 16), sharing of data and samples (17-19), and commercialisation and third parties (20 and 21). The refined recommendations resulted in an agreement of >80% for all recommendations. The SHARE initiative established the first recommendations for Paediatric Rheumatology collaborative research across borders in Europe. These provide strong support for an urgently needed European framework and evidence-based guidance for its implementation. Such changes will promote research in children with rheumatic diseases. © Article author(s) (or their employer(s) unless otherwise

With respect to materials data, this paper explores: how do we know what is available? how can data be accessed, interpreted, exchanged? what novel modes of presentation are now available? what organizations are active in this field and what are their programs? what improvements are needed? where do we go from here and how? Examples will be illustrated of specific materials databases available on the Internet from a variety of materials data fields, e.g. fundamental data, engineering design properties, environmental data, and materials safety data. While there is no question that large and widely varied bodies of data are accessible on the Internet, significant improvements are needed promptly. The paper concludes by summarizing these problems and possible means for their alleviation.

  4. Internet health information in the patient-provider dialogue.

    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.

    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.

    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.

    Online web-based interventions can be effective ancillary tools for managing diabetes. There is a high prevalence of diabetes in New Zealand Maori, and yet this group has generally been a low priority for web-based interventions due to perceptions of low Internet access and Internet literacy. To assess Internet access and literacy in New Zealanders with diabetes, especially high-risk Maori. A telephone survey of all patients with diabetes in an urban general practice. Internet access is assessed by Internet presence in the home, and Internet literacy by the ability to use email and the World Wide Web. One hundred percent response rate with 68 participants, including 38% Maori. Internet access for Maori was 70% and Internet literacy 41%. Internet access and literacy for Maori with diabetes may be higher than previously thought. Health policies may wish to focus effective and cost-efficient web-based interventions on this high diabetes risk group.

    Full Text Available Background and Objectives: Adequate access to oral and dental health services in childhood can reduce long-term complications in the following years of life. The objective of this study was to determine the barriers of access to children’s oral and dental health services from the point of view of mothers referring to health centers in Qom city. Methods: In this cross-sectional study, the statistical population included 325 mothers referred to health centers. Data were collected using a questionnaire consisted of items, including age, educational level, job, and barriers of access to oral health services. Data were analyzed using descriptive statistical indicators and logistic regression test. Results: In this study, lack of insurance coverage for dentistry costs (59.7% had the highest frequency in barriers of access to dental health services, followed by child's fear of dentistry (53.2% and high costs of dental services (49.8%. There was no significant relationship between mother's job and barriers of access to dental health services, but the chance of barriers of access to dental health services increased 1.60 times with father’s employment in government jobs. Also, the results showed that the chance of barriers of access to dental health services increased 3.60 times with residence in Pardisan region, on the other hand, the chance of access to the services, was improved up to 52% with residence in Tohid region. Conclusion: Expansion of insurance coverage of oral and dental health services and increase of public centers providing dental services can be eliminate the major part of barriers of access to these services. In addition, the proportional distribution of these services in different regions of the city can be effective in easy and low-cost access.

    Full Text Available 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.

    Poultry are one of the most badly treated animals in the modern world. It has been shown that they have high levels of both cognition and feelings, and as a result there has been a recent trend of promoting poultry welfare. There is also a tradition of keeping poultry as pets in some parts of the world. However, in modern cities and societies, it is often difficult to maintain contact with pets, particularly for office workers. We propose and describe a novel cybernetics system to use mobile and Internet technology to improve human-pet interaction. It can also be used for people who are allergic to touching animals and thus cannot stroke them directly. This interaction encompasses both visualization and tactile sensation of real objects.

    Use of the Internet to conduct randomised controlled trials is increasing, and provides potential to increase equity of access to medical research, increase the generalisability of trial results and decrease the costs involved in conducting large scale trials. Several studies have compared response rates, completeness of data, and reliability of surveys using the Internet and traditional methods, but very little is known about participants' attitudes towards Internet-based randomised trials or their experience of participating in an Internet-based trial. To obtain insights into the experiences and perspectives of participants in an Internet-based randomised controlled trial, their attitudes to the use of the Internet to conduct medical research, and their intentions regarding future participation in Internet research. All English speaking participants in a recently completed Internet randomised controlled trial were invited to participate in an online survey. 1246 invitations were emailed. 416 participants completed the survey between May and October 2009 (33% response rate). Reasons given for participating in the Internet RCT fell into 4 main areas: personal interest in the research question and outcome, ease of participation, an appreciation of the importance of research and altruistic reasons. Participants' comments and reflections on their experience of participating in a fully online trial were positive and less than half of participants would have participated in the trial had it been conducted using other means of data collection. However participants identified trade-offs between the benefits and downsides of participating in Internet-based trials. The main trade-off was between flexibility and convenience - a perceived benefit - and a lack connectedness and understanding - a perceived disadvantage. The other tradeoffs were in the areas of: ease or difficulty in use of the Internet; security, privacy and confidentiality issues; perceived benefits and

    Internet addiction disorder is a relatively new condition, and the criteria for its diagnosis have been developed only over the last several years. The criteria for Internet addiction remain controversial. We strive to further elucidate the clinical validity of the diagnostic criteria for Internet addiction. To test items of the diagnostic criteria for Internet addiction among adolescents, we conducted a clinical interview study of college students based on longitudinal data on their risky use of the Internet. Forty-one high-risk cases were selected from a 3-year 5-time point longitudinal survey of 716 college freshmen. We examined disputes relevant to symptoms and impairment in the DC-IA-A (Diagnostic Criteria for Internet Addiction among Taiwanese Adolescents). Of the 41 cases, 21 were diagnosed with Internet addiction via a psychiatric interview. In the Internet addiction disorder group, 23.8% of cases had a diagnosis of depression, whereas only 15.0% of the cases in the non-Internet addiction group had a diagnosis of depression. Two major criteria (A8 and A3) had low incidences in these high-risk college students and thus did not help provide a differential diagnosis between the groups. We suggest that A8, 'excessive effort spent on activities necessary to obtain access to the Internet', should be omitted, and that A3, 'tolerance: a marked increase in the duration of Internet use needed to achieve satisfaction', should be modified. A1 and A9 should be discussed regarding their role in the diagnosis of Internet addiction disorder. Additional well-designed studies examining the diagnostic criteria and the relationship between factors are needed. © 2015 S. Karger AG, Basel.

  11. Internet images of the speech pathology profession.

    2017-06-05

    group of people into the profession in the future. What is known about the topic? To date, research has not considered the promotional profile of allied health professionals on the Internet. There has been a lack of consideration of whether the way in which the professions are promoted may affect clients accessing allied health services or people entering careers. What does this paper add? This paper raises awareness of the lack of promotion of a diverse workforce in speech pathology and considers how this may affect changing the professional demographics in the future. It also provides a starting point for documentation in the form of a baseline for tracking future changes. It allows consideration of the fact that when designing health promotional and educational materials, it is crucial that diversity is displayed in the professional role, the client role and the setting in order to provide information and education to the general public about the health services provided. What are the implications for practitioners? The presentation of narrow demographics of both the professional and client may potentially affect people considering speech pathology as a future career. The appearance of narrow client demographics and diagnosis groups may also deter people from accessing services. For example, if the demonstrated images do not show older people accessing speech pathology services, then this may suggest that services are only for children. The results from the present case example are transferrable to other health professions with similar professional demographic profiles (e.g. occupational therapy). Consideration of the need to display a diverse client profile is relevant to all health and medical services, and demonstrates steps towards inclusiveness and increasing engagement of clients who may be currently less likely to access health services (including people who are Aboriginal or from a culturally and linguistically diverse background).

    Full Text Available Internet Banking developed due to increasing demand of online banking transactions. The biggest advantages of Internet Banking consist of complex banking solutions, 24 hours availability, quick and secure access to the back-end application through Internet. These advantages are due to the use of SOA (service-oriented architecture. SOA appeared as a necessity of companies to integrate big and independent portions of applications, in order to obtain an homogeneous functionality of the system. For the Internet Banking applications, SOA proved to be the optimal architectural solution, for a smoth integration between banking services from the front-end to the back-end.This paper intend to offer an insite analyse of the Internet Banking applications architecture integrated with other banking systems. A SOA oriented analyse will establish the scope of the integration architecture.

    2010-01-01

    A web-based application was developed to remotely view slide specimens and control all functions of a research-level light microscopy workstation, called AccessScope. Students and scientists with upper limb mobility and visual impairments are often unable to use a light microscope by themselves and must depend on others in its operation. Users with upper limb mobility impairments and low vision were recruited to assist in the design process of the AccessScope personal computer (PC) user interface. Participants with these disabilities were evaluated in their ability to use AccessScope to perform microscopical tasks. AccessScope usage was compared with inspecting prescanned slide images by grading participants' identification and understanding of histological features and knowledge of microscope operation. With AccessScope subjects were able to independently perform common light microscopy functions through an Internet browser by employing different PC pointing devices or accessibility software according to individual abilities. Subjects answered more histology and microscope usage questions correctly after first participating in an AccessScope test session. AccessScope allowed users with upper limb or visual impairments to successfully perform light microscopy without assistance. This unprecedented capability is crucial for students and scientists with disabilities to perform laboratory coursework or microscope-based research and pursue science, technology, engineering, and mathematics fields.

    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.

    2001-01-01

    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

    2009-01-01

    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

    Internet use has increased rapidly all over the world. Excessive Internet use tends to lead to the creation of a non-chemical addiction, most commonly known as "Internet addiction." The aim of this study was an assessment of the prevalence of Internet use and Internet addiction among school children aged 14-18 years in the Municipality of Novi Sad, Serbia, and influence of sociodemographic variables on Internet use. A cross-sectional study was conducted in Novi Sad among final-year students from elementary and first- and second-year students from high schools.The prevalence of Internet addiction was assessed by using Young's Diagnostic Questionnaire. Out of 553 participants, 62.7% were females, and the average age was 15.6 years. The sample consisted of 153 elementary school students and 400 high school students. Majority of respondents had a computer in their household. Our study showed widespread Internet use among adolescents. Facebook and YouTube were among most visited web-sites. The main purpose of Internet use was entertainment. Estimated prevalence of Internet addiction was high (18.7%), Mostly among younger adolescents (p = 0.013). Internet addiction was found in every fifth adolescent. Accessibility and availability of Internet use is constantly growing and therefore it is necessary to define more sensitive diagnostic tools for the assessment of Internet addiction and its underlying causes, in order to implement effective preventive programs.

    Full Text Available A partir de los años 90 las teorías feministas de la tecnología experimentan un optimismo renovado con la aparición de las TIC y el desarrollo de la tercera ola feminista. Sin embargo, la investigación en género y tecnología se ha centrado en estudiar la exclusión de las mujeres de las TIC e, inversamente, las experiencias de las mujeres y sus estrategias para incluirse en las TIC han recibido menos atención. Motivadas por nuestras experiencias tecnoactivistas y la observación de una remarcable presencia de mujeres en ellas, con Donestech, iniciamos un proyecto de investigación sobre los accesos, usos y deseos de las mujeres en las TIC. A través de una investigación ciberfeminista recogimos, analizamos y visibilizamos las experiencias y opiniones de las mujeres en las TIC. Nuestros resultados sugieren que las trayectorias de inclusión y acceso de las mujeres en las TIC son diversas, así como heterogéneos son los usos que hacen de ellas, destacando el rol jugado por Internet en todo ello. Además mostramos que las mujeres en las TIC son curiosas y entusiastas, que quieren empoderarse y compartir el conocimiento. Finalmente, les disgusta y desconfían de las relaciones de poder existentes en los mundos tecnológicos, manteniendo una actitud crítica y creativa hacia las TIC.Since the 90’s the feminist theories of technology have experienced a renewed optimism with the rise of ICT and the development of the third-wave feminisms. However, Research on gender and technology still focuses on studying the exclusion of women from ICT. Conversely, women’s experiences and their strategies leading to their inclusion in ICT has received less attention. Motivated by our previous experience in technoactivism and the observation of a remarkable presence of women, within the Donestech Collective, we initiated a research project on the access, uses and desires of women who were involved in technology.

    Australia is one of the least densely populated countries in the world, with a population concentrated on or around coastal areas. Up to 33% of the Australian population are likely to have untreated dental decay, while people with inadequate dentition (fewer than 21 teeth) account for up to 34% of Australian adults. Historically, inadequate access to public dental care has resulted in long waiting lists, received much media coverage and been the subject of a new federal and state initiative. The objective of this research was to gauge the potential for reducing the national dental waiting list through geographical advantage, which could arise from subcontracting the delivery of subsidised dental care to the existing network of private dental clinics across Australia. Eligible population data were collected from the Australian Bureau of Statistics website. Waiting list data from across Australia were collected from publicly available sources and confirmed through direct communication with each individual state or territory dental health body. Quantum geographic information system software was used to map distribution of the eligible population across Australia by statistical area, and to plot locations of government and private dental clinics. Catchment areas of 5 km for metropolitan clinics and 5 km and 50 km for rural clinics were defined. The number of people on the waiting list and those eligible for subsidised dental care covered by each of the catchment areas was calculated. Percentage of the eligible population and those on the waiting list that could benefit from the potential improvement in geographic access was ascertained for metropolitan and rural residents. Fifty three percent of people on the waiting list resided within metropolitan areas. Rural and remote residents made up 47% of the population waiting to receive care.

    Full Text Available This work was a part of a broader empirical study of Internet users with excessive and dysfunctional Internet use symptoms. The aim of this particular article was to describe user profiles of Internet addicts in Serbia. The study recruited 100 subjects in total, 50 in both the clinical and control group. The clinical group included the Internet users who asked for professional help due to the symptoms of the excessive Internet use and fulfilled the diagnostic criteria for Internet behavior disorder proposed by the American Psychology Association. The results have shown that population with Internet addiction symptoms equally included both males and females, mostly adolescent and younger population, teenagers and university students, persons with higher income and users from economically more developed areas of Serbia. The user profile of this group is characterized by frequent logging on with intervals of several hours online at one time, mainly in the evening or at night, and also intensive negative reactions to any form of Internet access deprivation. By means of factor analysis, three dimensions of pathological use have been established: mixed type with particular need for up-to-date information, social interaction addiction and need for fun-seeking, namely pursuing hobbies online (cyberpornography, online games, music, art and so on.

  12. A World-Wide Web radiology teaching file server on the Internet.

    Radiology departments have traditionally used film-based collections of interesting cases for teaching purposes. Film-based files are expensive to create and duplicate, and they physically occupy considerable space. As one solution to these problems, our department created an on-line radiology teaching file in digital format. Our teaching file resides on a Macintosh Quadra 700 computer that is connected to the Internet, a worldwide network of interconnected computers, via our campus Ethernet network. Our digital teaching file images and text are composed in HyperText Markup Language (HTML) and are made available to the world with Webserver software known as MacHTTP. These teaching files are accessed using World-Wide Web (WWW) client software such as Mosaic, MacWeb, or Netscape. Our digital teaching file is available at no charge to anyone in the world with access to the Internet and WWW client software. Our radiology residents can access this file via several workstations in our department. Mosaic is an easy-to-use interface, and the use of our digital teaching file has increased significantly. In the 3 months since its creation, our teaching file has been accessed not only by our radiology residents but also by hundreds of other users in 33 countries. Use of Mosaic and the WWW format has resulted in an easy-to-use hypertext interface to the Internet, which allows even persons with little computer experience to navigate through the Internet, read text files, view images (stills and movies), and download files by merely pointing with the mouse and clicking on items of interest. This has allowed us to maintain a central teaching file that is physically small and easy to share with all the hospitals in our system. We invite the worldwide radiology community to access these files and to submit cases from their own teaching files to share with the rest of the world.

    In the Model for End-Stage Liver Disease (MELD) system, patients with "MELD exceptions" points may have unfair privilege in the competition for liver grafts. Furthermore, organ distribution following identical ABO blood types may also result in unjust organ allocation. The aim of this study was to investigate access to liver transplantation in a tertiary Brazilian center, regarding "MELD exceptions" situations and among ABO-blood groups. A total of 465 adult patients on the liver waitlist from August 2015 to August 2016 were followed up until August 2017. Patients were divided into groups according to ABO-blood type and presence of "exceptions points." No differences in outcomes were observed among ABO-blood groups. However, patients from B and AB blood types spent less time on the list than patients from A and O groups (median, 46, 176, 415, and 401 days, respectively; P = .03). "Exceptions points" were granted for 141 patients (30.1%), hepatocellular carcinoma being the most common reason (52.4%). Patients with "exceptions points" showed higher transplantation rate, lower mortality on the list, and lower delta-MELD than non-exceptions patients (56.7% vs 19.1% [P blood types, despite shorter time on the waitlist for AB and B groups. The current MELD exception system provides advantages for candidates with "exception points," resulting in superior outcomes compared with those without exceptions. Copyright © 2018 Elsevier Inc.

    Bateman, D N; Good, A M

    2006-08-01

    In 1999, the UK adopted a policy of using TOXBASE, an internet service available free to registered National Health Service (NHS) departments and professionals, as the first point of information on poisoning. This was the first use worldwide of the internet for provision of clinical advice at a national level. We report the impact on database usage and NPIS telephone call loads. Trends in the pattern of TOXBASE usage from 2000-2004 are reported by user category. Information on the monographs accessed most frequently was also extracted from the webserver and sorted by user category. The numbers of telephone calls to the National Poisons Information Service (NPIS) were extracted from NPIS annual reports. Numbers of database logons increased 3.5 fold from 102,352 in 2000 to 368,079 in 2004, with a total of 789,295 accesses to product monographs in 2004. Registered users increased almost tenfold, with approximately half accessing the database at least once a year. Telephone calls to the NPIS dropped by over half. Total contacts with NPIS (web and telephone) increased 50%. Major users in 2004 were hospital emergency departments (60.5% of logons) and NHS public access helplines (NHS Direct and NHS24) (29.4%). Different user groups access different parts of the database. Emergency departments access printable fact sheets for about 10% of monographs they access. Provision of poisons information by the internet has been successful in reducing NPIS call loads. Provision of basic poisons information by this method appears to be acceptable to different professional groups, and to be effective in reducing telephone call loads and increasing service cost effectiveness.

    nutritional content of meals consumed seems unaffected by the introduction of a healthy-labelled meal on the menu. Even if easily accessible and understood, menu labelling therefore seems inefficient in promoting healthier meal choices. Factors influencing meal consumption are meal ingredients and the order......This paper analyses the effect on meal consumption away from home of a point-of-purchase healthy symbol.

    Nationally 62% of individuals in Ireland have internet access. Previous published work has suggested that internet use is higher among those with low back pain. We aimed to determine the levels of internet access and use amongst an elective spinal outpatient population and determine what characteristics influence these. We distributed a self-designed questionnaire to patients attending elective spinal outpatient clinics. Data including demographics, history of surgery, number of visits, level of satisfaction with previous consultations, access to the internet, possession of health insurance, and details regarding use of the internet to research one\\'s spinal complaint were collected. 213 patients completed the questionnaire. 159 (75%) had access to the internet. Of this group 48 (23%) used the internet to research their spinal condition. Increasing age, higher education level, and possession of health insurance were all significantly associated with access to the internet (p < 0.05). A higher education level predicted greater internet use while possession of insurance weakly predicted non-use (p < 0.05). In our practice, internet access is consistent with national statistics and use is comparable to previous reports. Approximately, one quarter of outpatients will use the internet to research their spinal condition. Should we use this medium to disseminate information we need to be aware some groups may not have access.
