The major objective of this chapter was to test the effect of online time and adoption time on the frequency of transactional use of the Internet. Transactional use of the Internet includes activities such as buying products, banking, and investing online. Findings support the hypothesis that online time and adoption time positively and significantly influence the frequency of transactional use of the Internet. Theoretical and strategic implications and recommendations for future research are presented

Acquisition, Distribution and Perspectives of Healthcare Information in Complementary and Alternative Medicines (CAM)

Merged with duplicate record 10026.1/2500 on 06.20.2017 by CS (TIS)From April 2001 until September 2005 1 worked as a Pilkington research fellow at the Department of Complementary Medicine, University of Exeter, which in 2002 was integrated as a unit of the Peninsula Medical School. All the publications presented here have been carried out during my time of employment in this post at the Complementary Medicine Unit of the Peninsula Medical School in Exeter, United Kingdom. During the first few months of my research post in 2001 1 recognized the importance of the Internet as a tool to obtain healthcare information. Under the supervision of Professor Edzard Ernst, director of CAM, I carried out five Internet surveys, of which I collected and summarized the data and drafted the first version of the manuscripts, which were then finalized by Professor Ernst's comments: * Health risks over the Internet: advice offered by'medical herbalists' to a pregnant woman. * Reflexologists' responses to a patient with abdominal pain -a survey on Internet advice. * Internet advice by acupuncturists -a risk factor for cardiovascular patients? * Are asthma sufferers at risk when consulting chiropractors over the Internet? * Aspects of MMR / MMR vaccination advice over the Internet

Adoption of wireless internet parks: An empirical study in Qatar

This paper examines the adoption of free wireless internet parks (iPark) by Qatari citizens as means of accessing electronic services from public parks. The Qatar government has launched the iPark concept with a view of providing free internet access for all citizens while enjoying the outdoors. By offering free wireless Internet access, the Qatari government encourages its citizen's to actively participate in the global information society with a view of bridging the digital divide. Using a survey based study this research set out to examine the Qatari citizens' perceptions of the iPark initiative. Results of the survey showed that there is a positive level of relation between the independent variables, usefulness, ease of use, Internet safety, and Internet speed/response time and one dependent variable, intention to use the iPark in Qatar. The paper provides a discussion on the key findings, research implications, limitations, and future directions for the iPark initiative in Qatar

Will 5G See its Blind Side? Evolving 5G for Universal Internet Access

Internet has shown itself to be a catalyst for economic growth and social equity but its potency is thwarted by the fact that the Internet is off limits for the vast majority of human beings. Mobile phones---the fastest growing technology in the world that now reaches around 80\% of humanity---can enable universal Internet access if it can resolve coverage problems that have historically plagued previous cellular architectures (2G, 3G, and 4G). These conventional architectures have not been able to sustain universal service provisioning since these architectures depend on having enough users per cell for their economic viability and thus are not well suited to rural areas (which are by definition sparsely populated). The new generation of mobile cellular technology (5G), currently in a formative phase and expected to be finalized around 2020, is aimed at orders of magnitude performance enhancement. 5G offers a clean slate to network designers and can be molded into an architecture also amenable to universal Internet provisioning. Keeping in mind the great social benefits of democratizing Internet and connectivity, we believe that the time is ripe for emphasizing universal Internet provisioning as an important goal on the 5G research agenda. In this paper, we investigate the opportunities and challenges in utilizing 5G for global access to the Internet for all (GAIA). We have also identified the major technical issues involved in a 5G-based GAIA solution and have set up a future research agenda by defining open research problems

Leveraging upon standards to build the Internet of things

Smart embedded objects will become an important part of what is called the Internet of Things. However, the integration of embedded devices into the Internet introduces several challenges, since many of the existing Internet technologies and protocols were not designed for this class of devices. In the past few years, there were many efforts to enable the extension of Internet technologies to constrained devices. Initially, this resulted in proprietary protocols and architectures. Later, the integration of constrained devices into the Internet was embraced by IETF, moving towards standardized IP-based protocols. Long time, most efforts were focusing on the networking layer. More recently, the IETF CoRE working group started working on an embedded counterpart of HTTP, allowing the integration of constrained devices into existing service networks. In this paper, we will briefly review the history of integrating constrained devices into the Internet, with a prime focus on the IETF standardization work in the ROLL and CoRE working groups. This is further complemented with some research results that illustrate how these novel technologies can be extended or used to tackle other problems.The research leading to these results has received funding from the European Union's Seventh Framework Programme (FP7/2 007-2013) under grant agreement n°258885 (SPITFIRE project), from the iMinds ICON projects GreenWeCan and O’CareCloudS, and a VLI R PhD scholarship to Isam Ishaq

Internet skills performance tests: are people ready for eHealth?

Background:\ud Despite the amount of online health information, there are several barriers that limit the Internet’s adoption as a source of health information. One of these barriers is highlighted in conceptualizations of the digital divide which include the differential possession of Internet skills, or “eHealth literacy”. Most measures of Internet skills among populations at large use self-assessments. The research discussed here applies a multifaceted definition of Internet skills and uses actual performance tests.\ud \ud Objective:\ud The purpose of this study was to assess how ready a sample of the general population is for eHealth. More specifically, four types of Internet skills were measured in a performance test in which subjects had to complete health-related assignments on the Internet.\ud \ud Methods:\ud From November 1, 2009, through February 28, 2010, 88 subjects participated in the study. Subjects were randomly selected from a telephone directory. A selective quota sample was used divided over equal subsamples of gender, age, and education. Each subject had to accomplish assignments on the Internet. The Internet skills accounted for were categorized as operational (basic skills to use the Internet), formal (navigation and orientation), information (finding information), and strategic (using the information for personal benefits). The tests took approximately 1.5 hours and were conducted in a University office, making the setting equally new for all. Successful completion and time spent on the assignments—the two main outcomes—were directly measured by the test leader.\ud \ud Results:\ud The subjects successfully completed an average of 73% (5.8/8) of the operational Internet skill tasks and an average of 73% (2.9/4) of the formal Internet skill tasks. Of the information Internet skills tasks, an average of 50% (1.5/3) was completed successfully and, of the strategic Internet skills tasks, 35% (0.7/2). Only 28% (25/88) of the subjects were able to successfully complete all operational skills tasks, 39% (34/88) all formal skills tasks, 13% (11/88) all information skills tasks, and 20% (18/88) both the strategic skill tasks. The time spent on the assignments varied substantially. Age and education were the most important contributors to the operational and formal Internet skills. Regarding the formal Internet skills, years of Internet experience also had some influence. Educational level of attainment was the most important contributor to the information and strategic Internet skills.\ud \ud Conclusions:\ud Although the amount of online health-related information and services is consistently growing, it appears that the general population lacks the skills to keep up. Most problematic appear to be the lack of information and strategic Internet skills, which, in the context of health, are very important. The lack of these skills is also problematic for members of younger generations, who are often considered skilled Internet users. This primarily seems to account for the operational and formal Internet skills. The results of the study strongly call for policies to increase the level of Internet skills

A review of research ethics in internet-based research

Internet-based research methods can include; on-line surveys, web page content analysis, videoconferencing for on-line focus groups and/ or interviews, analysis of ‘e’ conversations through social networking sites, email, chat rooms, discussion boards and/ or blogs. Over the last ten years an upsurge in Internet Based Research (IBR) has led to increased interest in IBR and research ethics. Here we present some ethical guidelines for IBR whilst at the same time accepting that it would be unrealistic to expect that any single set of guidelines can cover all ethical situations concerning IBR). There is simply too much diversity across internet cultures, values and modes of operation for that to be the case. Perhaps the most useful solution to the complex challenges of IRB lies with a form of ‘negotiated ethics’, a situated approach grounded in the specifics of the online community, the methodology and the research question(s). This does not mean an ‘anything goes’ relativist approach, rather an open, pluralistic policy in relation to IBR ethical issues (Ess, 2009; AoIR, 2002)

Internet addiction: a systematic review of epidemiological research for the last decade

In the last decade, Internet usage has grown tremendously on a global scale. The increasing popularity and frequency of Internet use has led to an increasing number of reports highlighting the potential negative consequences of overuse. Over the last decade, research into Internet addiction has proliferated. This paper reviews the existing 68 epidemiological studies of Internet addiction that (i) contain quantitative empirical data, (ii) have been published after 2000, (iii) include an analysis relating to Internet addiction, (iv) include a minimum of 1000 participants, and (v) provide a full-text article published in English using the database Web of Science. Assessment tools and conceptualisations, prevalence, and associated factors in adolescents and adults are scrutinised. The results reveal the following. First, no gold standard of Internet addiction classification exists as 21 different assessment instruments have been identified. They adopt official criteria for substance use disorders or pathological gambling, no or few criteria relevant for an addiction diagnosis, time spent online, or resulting problems. Second, reported prevalence rates differ as a consequence of different assessment tools and cut-offs, ranging from 0.8% in Italy to 26.7% in Hong Kong. Third, Internet addiction is associated with a number of sociodemographic, Internet use, and psychosocial factors, as well as comorbid symptoms and disorder in adolescents and adults. The results indicate that a number of core symptoms (i.e., compulsive use, negative outcomes and salience) appear relevant for diagnosis, which assimilates Internet addiction and other addictive disorders and also differentiates them, implying a conceptualisation as syndrome with similar etiology and components, but different expressions of addictions. Limitations include the exclusion of studies with smaller sample sizes and studies focusing on specific online behaviours. Conclusively, there is a need for nosological precision so that ultimately those in need can be helped by translating the scientific evidence established in the context of Internet addiction into actual clinical practice
