Self-reported use of ICT (Information and communication technology) uptake in 2002 and discomfort amongst Finns aged 45-66

In recent years the use of new technical equipment and the Internet by middle-aged people has increased. This paper presents middle-aged people’s (45 years old or older) usage of new technical equipment and analyses how their (2704 persons) symptoms are associated with the equipment. Over 70% of Finland’s middle-aged population use mobile phones daily and less than 30% use desktop computers at leisure. For example, over 80% of middle-aged people had sometimes or often experienced pain, numbness or aches in the neck and about 70% had aches in the hip and lower back. The use of new technical equipment among the group of people who are outside working life was smaller than the people’s usage in general. In the future, when new technical equipment is developed, it is important to take into account, that people (outside working life) do not use, e.g., the Internet as much as people in general. The working environment will be much more ergonomic also at home and the Internet services will be easy to use for almost everyone, even those who have little experience or knowledge of computers and the Internet.

Mobile networking through Mobile IP

Mobile IP is a proposed standard protocol that builds on the Internet Protocol by making mobility transparent to applications and higher level protocols like TCP. Mobile IP (RFC 2002) is a standard proposed by a working group within the Internet Engineering Task Force; it allows the mobile node to use two IP addresses: a fixed home address and a care-of address that changes at each new point of attachment. The article presents the Mobile IP standard in moderate technical detail and points the reader toward a wealth of further information. Is also describes how Mobile IP will change with IP version 6, the product of a major effort within the IETF to engineer an eventual replacement for the current version of IP. Although IPv6 will support mobility to a greater degree than IPv4, it will still need Mobile IP to make mobility transparent to applications and higher level protocols such as TCP. There is a great deal of interest in mobile computing and apparently in Mobile IP as a way to provide for it. A quick Web search for items related to Mobile IP returned over 60,000 hits-impressive even given the notorious lack of selectivity for such procedures. Mobile IP forms the basis either directly or indirectly of many current research efforts and products. The Cellular Digital Packet Data (CDPD), for example, has created a widely deployed communications infrastructure based on a previous draft specification of the protocol. In addition, most major router vendors have developed implementations for Mobile IP

An Empirical Study of Use Contexts in the Mobile Internet,Focusing on the Usability of Information Architecture

The mobile Internet—accessing the Internet via a mobile device—has become quite popular recently. The mobile Internet is mainly different from the stationary Internet because it may be used in various contexts, whereas the stationary Internet is mostly used in pre-determined environments. However, it is unclear when the mobile Internet is used most frequently, and in what context it is most useful. A greater understanding of the contexts for using the mobile Internet will relieve usability problems that mobile Internet users often encounter.This paper proposes a conceptual framework of use contexts, which includes various facets of contexts related to the mobile Internet. It then presents the results of an exploratory study in which the use contexts for the mobile Internet and corresponding usability problems have been empirically monitored. The results indicate that use of the mobile Internet is heavily clustered around a few key contexts, rather than dispersed widely in diverse contexts. Moreover, different contexts are found to cause different kinds of usability problems. The paper ends with theoretical and practical implications of the study results.

Performance of GSM networks with general packet radio services

Recently, most of the mobile network providers start to introduce general packet radio service (GPRS) in their existing GSM networks. GPRS is the technology that will enable more efficient Internet applications to run on mobile networks even before the installation of 3G systems. However, it is not yet clearly understood, how the new data services will affect the overall network performance. This paper provides a framework for analytical performance evaluation of a single GSM/GPRS cell based on a multidimensional Markov chain model. Important performance measures like new call and handover blocking probabilities, moments of the blocking period distributions, achievable average data rates and resource utilization are determined. Introducing a new connection admission control (CAC) algorithm, different partitioning strategies between GSM and GPRS resources are investigated. Finally, the influence of typical GPRS applications like Internet browsing on traditional GSM services has been studied.     

Mobile devices and intelligent agents—towards a new generation of applications and services

If mobile computing is to become the pre-dominant computer usage paradigm in the coming years as is widely anticipated, a substantial increase in the demand for mobile computing applications and services will arise. How best to engineer such applications remains an open question and is naturally the focus of much research. In this article, we propose the use of intelligent agents as the constituent entities around which such applications and services can be conceptualised and realised. We describe the design and implementation of Gulliver’s Genie, an archetypal ubiquitous computing application that commissions a collaborative embedded agents approach.     

Framework for usability: healthcare professionals and the Internet

The vastness and diversity of the Internet make it an emerging choice as an information repository and dissemination mechanism for healthcare-related information. The objective of this research is to characterize empirically the use of the Internet by a variety of healthcare professionals as well as to gauge perceptions of the Internet as a tool for information retrieval. This was accomplished through use of a questionnaire explicitly designed to gauge usage and perceptions of the Internet. Differences were detected between individual occupations of healthcare professionals with respect to Internet use and opinions concerning possible enhancements to the Internet. It was found that users' subjective experiences with the World-Wide Web (WWW) were more important than self-reported user knowledge when indicating the value of enhancements to the search process on the WWW. The methodological implications of the research together with a conceptual framework for usability that captures the essence of Internet usability in healthcare are presented. Directions for future research are provided.     

User interface guidelines for the control of interactive television systems via smart phone applications

There are a growing number of smart phone applications allowing the user to control their television, set-top box or other entertainment devices. The success of these applications is limited. Based on findings from media studies in Austria and France focusing on how people currently use their TV and iTV systems and associated devices, this article describes recommendations for the design of a smart phone application enabling users to control Internet Protocol Television (IPTV) systems including all connected entertainment devices. Recommendations include the need to allow users to control devices that are related to the IPTV experience (not only the set-top box or television set) and the focus on scenarios of usage like supporting listening to music, enjoying a movie or controlling the connected home. Based on similarities and differences found in the two samples, future smart phone applications for controlling TV will only succeed if they provide meaningful functionalities that satisfy the (varying) user needs, support personalisation and personal usage and respect the limitations of mobile phones with respect to possible parallel activities performed.     

Use Contexts for the Mobile Internet: A Longitudinal Study Monitoring Actual Use of Mobile Internet Services

The mobile Internet, which gives access to the World Wide Web through a mobile device, has been gaining in popularity. The mobile Internet differs from the traditional stationary Internet in that it can be used in a wider variety of contexts. However, no studies have identified the contexts in which mobile Internet services are used most frequently, or determined which contexts exert significant influence on a user's choice of mobile service. This article proposes a framework of use contexts that reflects the characteristics of the mobile Internet. To explore these contexts, a research method was devised and a longitudinal monitoring study was conducted. The results indicate that mobile Internet use is heavily clustered around a few key contexts, rather than dispersed widely over diverse contexts. Further, participants in the monitoring study were found to concentrate their use on a few mobile services, rather than on exploring diverse services. Perhaps most interestingly, some contextual factors were found to correlate closely with the selection of specific mobile Internet services. On the basis of these results, the article concludes with implications for developers of mobile Internet services.

Measuring Internet usage: The Israeli case

The article describes two instruments for measuring Internet Usage and the changes in subjects’ Internet usage following a controlled intervention. It focuses on the use of usage and lack of usage for measuring the digital gap. The “digital gap” is defined as the gap between individuals with and without access to technology (telephones, computers, Internet access) and related services. Since its emergence, the Internet has become the most important form of information and communication technology (ICT).The goal of the present research was to develop ways of measuring Internet usage for different segments of the Israeli population (it can also be used to measure Internet usage outside Israel). For the past few years, the Israeli government has sponsored programs designed to increase Internet usage in specific segments of the Israeli population. Some of these programs have been “controlled programs”. Controlled Internet Usage Programs are planned and monitored programs, which use research methods to discover whether they have increased Internet usage and changed Internet habits.The population of Internet users in Israel is presently 45.8% (compared with 68.2% in the US population). The past 5 years has witnessed a significant rise in the number of Internet users in the West in general and in Israel specifically: an increase of 152% in the number of Israeli households connected to the Internet during the period 2000–2005.However, large differences are apparent between the stronger and weaker sections of the Israeli population where the Internet is concerned, and controlled intervention is therefore a very important means of reducing these discrepancies.The present article describes two measurement instruments: the first instrument examines on-line proficiency, while the second determines patterns of Internet use and the status of respondents’ “Internet awareness”.The instruments were built to determine the reduction in the digital divide associated with Internet usage following controlled intervention, and the population's Internet usage status before and after intervention. The difference between the two measurements represents the increase or decrease in Internet usage.These two instruments may be used by agencies making decisions about resource disbursement to reduce the digital divide in a variety of populations.     

Internet addiction among adolescents in Lebanon

Internet addiction has been a subject of research since 1996. In step with this trend, this study aims to illuminate Internet addiction in Lebanon based on research evidence. The timing of this study coincides with the growing rate of penetration of Internet service across the country and with current plans to improve this service. This study investigates Internet usage among adolescents, who are the most vulnerable to Internet addiction in the population. Permission to access schools to conduct this research was obtained from the Ministry of Education and Higher Education. A web-based questionnaire was completed by 833 intermediate and secondary students from public and private schools. The questionnaire included items on demographic information and Internet usage and an Arabic version of Young’s Internet Addiction Test (YIAT). The results showed that 4.2% of the sample had significant problems. Furthermore, the more problematic Internet use (PIU) was, the less the Internet was used for information and research, and the more it was used for entertainment. PIU is driven by deficiency needs fuelled by the use of interactive applications. The more deficient the need, the greater the obsession with top-notch interactive applications, and the less frequent the usage of non-interactive applications.     

Retracted: An Empirical Study of an Internet Marketing Strategy for Search Engine Optimization

Over the past few years, more and more Internet visitors are reaching websites through search engines rather than through direct links from another web page. Search engines have come to occupy a prominent position in the online world and are being used to find all kinds of information including things, events, people, and places. The search engine is also coming to play a greater role as a critical link between firms that use the Internet to build their image and find their target customers. How to achieve a high ranking in such search results given certain search words or phrases has become an issue of much interest in Internet marketing. The purpose of the current study is to develop a search engine optimization (SEO) mechanism that can be used by an enterprise to improve the ranking of its website in the search engine results. Social networking sites are included in our exploration of Internet marketing strategy. The proposed mechanism is then applied in the operations of an online ebook store. The website rankings obtained from two well‐known online search engines (Google and Yahoo) are evaluated in efforts to explore a better strategy to ensure higher rankings. The results reveal that a well‐designed SEO strategy, with the incorporation of social networking, can effectively enhance the website's visibility and exposure. Such a strategy will eventually contribute to overall site traffic and improve interaction with customers. © 2012 Wiley Periodicals, Inc.     

Internet use that reproduces educational inequalities: Evidence from big data

Although the Internet has become ubiquitous in students' lives in school and at home, little is known about whether the Internet is used to close or reproduce educational inequalities. Drawing upon Bourdieu's notion of capital, there are two kinds of Internet use: capital-enhancing versus entertainment. This study used two big data analytic tools to examine interest in and usage of two highly popular websites that primarily target children and adolescents: KhanAcademy.org and CartoonNetwork.com. The former represents a capital-enhancing use of the Internet, while the latter represents an Internet use for entertainment. Data analysis revealed that high sociodemographic status was positively correlated with interest in Khan Academy, while low sociodemographic status was positively correlated with interest in Cartoon Network. This study provided some evidence that existing educational inequalities may be reproduced through unequal Internet use.     

Socially inspired search and ranking in mobile social networking: concepts and challenges

In this paper, we provide an overview of challenges in mobile search and ranking, and envision the fundamental features that should be satisfied. We argue that two principles will help improve the relevance and quality of mobile search and ranking: the first one is to examine both intrinsic content features and context of items (usage statistics and social features, etc.); and the second one lies in that no algorithms can replace the objectivity of a human being—let users define the sites that they feel are relevant, leverage their social networks, and over time see their results become highly personalized. Specifically, wireless-virtualcommunity- based mobile search and ranking architecture is proposed in this paper, in which communities act as a first class abstraction for information sharing. Then, we introduce briefly the potential procedures of achieving high relevance and quality in mobile search and ranking based on wireless virtual community.
