The digital divide as a complex and dynamic phenomenon

The purpose of this article is to propose a fruitful analytical framework for data supposedly related to the concept of the so-called digital divide. The extent and the nature of this divide depend on the kind of access defined. Considering the possession of hardware, growing divides among different categories of income, employment, education, age, and ethnicity can be proved to have existed in the 1980s and 1990s according to official American and Dutch statistics. If only by effects of saturation, these gaps will more or less close. However, it is shown that differential access of skills and usage is likely to increase. The growth of a usage gap is projected. Multivariate analyses of Dutch official statistics reveal the striking effect of age and gender as compared to education. The usage gap is related to the evolution of the information and network society. Finally, policy perspectives are discussed.

The digital divide shifts to differences in usage

In a representative survey of the Dutch population we found that people with low levels of education and disabled people are using the Internet for more hours a day in their spare time than higher educated and employed populations. To explain this finding, we investigated what these people are doing online. The first contribution is a theoretically validated cluster of Internet usage types: information, news, personal development, social interaction, leisure, commercial transaction and gaming. The second contribution is that, based on this classification, we were able to identify a number of usage differences, including those demonstrated by people with different gender, age, education and Internet experience, that are often observed in digital divide literature. The general conclusion is that when the Internet matures, it will increasingly reflect known social, economic and cultural relationships of the offline world, including inequalities.In a representative survey of the Dutch population we found that people with low levels of education and disabled people are using the Internet for more hours a day in their spare time than higher educated and employed populations.

Internet Skills and the Digital Divide

Because of the growing amount of information on the internet and people’s increasing dependence on information, internet skills should be considered as a vital resource in contemporary society. This article focuses on the differential possession of internet skills among the Dutch population. In two studies, an in-depth range of internet skills are measured by charging subjects assignments to be accomplished on the internet. Subjects were recruited by applying a random stratified sampling method over gender, age, and education. While the level of operational and formal internet skills appeared quite high, the level of information and strategic internet skills is questionable. Whereas education appeared an important contributor to all skill levels, age only appeared a significant contributor to operational and formal skills. The results strengthen the findings that the original digital divide of physical internet access has evolved into a divide that includes differences in skills to use the internet.Because of the growing amount of information on the internet and people’s increasing dependence on information, internet skills should be considered as a vital resource in contemporary society.

Disturbance Observers for Rigid Mechanical Systems: Equivalence, Stability, and Design

Mechanical (direct-drive) systems designed for high-speed and high-accuracy applications require control systems that eliminate the influence of disturbances like cogging forces and friction. One way to achieve additional disturbance rejection is to extend the usual (P(I)D) controller with a disturbance observer. There are two distinct ways to design, represent, and implement a disturbance observer, but in this paper it is shown that the one is a generalization of the other. A general systematic design procedure for disturbance observers that incorporates stability requirements is given. Furthermore, it is shown that a disturbance observer can be transformed into a classical feedback structure, enabling numerous well-known tools to be used for the design and analysis of disturbance observers. Using this feedback interpretation of disturbance observers, it will be shown that a disturbance observer based robot tracking controller can be constructed that is equivalent to a passivity based controller. By this equivalence not only stability proofs of the disturbance observer based controller are obtained, but it also provides more transparent controller parameter selection rules for the passivity based controller.

Explaining the acceptance and use of government Internet services: a multivariate analysis of 2006 survey data in the Netherlands

In this article, an attempt is made to explain the descriptive data of a large-scale representative survey of the use of government Internet services by the Dutch population in 2006 by means of a multidisciplinary model of technology acceptance and use that is applied to these services. Ultimately, the model is tested with structural equation modeling techniques. It appears to fit to the data after some modifications and exclusion of variables. The ultimate model could be used to explain the acceptance and use of government Internet services. The larger correlation model could serve as a framework for research of Internet services in general. n nThe social–demographic and psychological factors usually investigated in new technology acceptance and usage research do not prove to be strong here. Instead, it is demonstrated that the availability of Internet services, the knowledge of this availability, the preference to use digital channels, and the ability and experience to do this are the primary conditions. n nThe most general conclusion drawn is that the acceptance and use of government Internet services is a matter of learning, and that acceptance and use should be analyzed as a dynamic process. People will stick to their habits of using traditional channels unless they happen to learn a better alternative. n nGovernments are recommended to add a demand-side orientation and benchmarking for the supply of government Internet services and to develop service tracking technologies monitoring usage and users.

Using the Internet: Skill related problems in users' online behavior

This study extends the conventional and superficial notion of measuring digital skills by proposing definitions for operational, formal, information and strategic skills. The main purpose was to identify individual skill related problems that users experience when navigating the Internet. In particular, lower levels of education and aging seem to contribute to the amount of experienced operational and formal skill related problems. With respect to information skills, higher levels of education seem to perform best. Age did not seem to contribute to information skill related problems. Results did reveal that age had a negative effect on selecting irrelevant search results. Individual strategic Internet skill related problems occurred often, with the exception of subjects with higher levels of education. Younger subjects experienced far less operational and formal skill related problems, but there was no difference regarding information and strategic skill related problems.

Internet Skills Performance Tests: Are People Ready for eHealth?

Background 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. Objective 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. Methods 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. Results 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. Conclusions 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.

Searching for the Holy Grail Images of Interactive Television

This article is about the interactivity of interactive television (ITV). It is both a theoretical elaboration of the concepts of interactivity and interactive television and a presentation of a survey among 74 American, Asian and European corporate experts of ITV. First, operational definitions of the concepts of interactivity and interactive television are presented as scholarly images of ITV. Then the main results of a questionnaire investigating corporate expert images of ITV are presented. These images are assessed by the investigators to be rather weak and imprecise. Still, the experts concerned are desperately seeking a suitable and concrete business model of ITV, as a kind of Holy Grail. Experts from the world of television production and internet production appear to have different images of interactivity, applications of ITV and the future of television. Finally, the authors present the main components of business models of ITV and the future prospects of this medium.This article is about the interactivity of interactive television (ITV).

Personalization in the public sector: An inventory of organizational and user obstacles towards personalization of electronic services in the public sector

The public sector more and more deploys personalized e-government services. Personalization offers great opportunities to make communication more effective and efficient, to infer and predict citizens behavior and to even influence behavior. However, some drawbacks must be considered. Important organizational barriers hinder the implementation of personalized e-government services and important user obstacles, such as access, trust, control, and privacy, have to be overcome to make fruitful use of those personalized e-government services.

Why e-government usage lags behind: explaining the gap between potential and actual usage of electronic public services in the netherlands

Most of the EU-15 countries illustrate a gap between potential usage and actual usage of electronic public services. Using a model of four successive kinds of access to digital technologies a number of explanations are sought. They are tested in the case of current Dutch electronic governmental service usage. Motivational access indicates that there is a part of the Dutch population that doesn’t have sufficient motivation for using computers and the Internet. It also appears that even in the Netherlands, a top country regarding Internet and broadband connections, physical access cannot be taken for granted. Insufficient digital skills produce serious problems as well. But the most striking facts are found in the context of usage access. Here we have observed a lack of user orientation in Dutch e-government services. It appears that the Dutch government doesn’t know what citizens want, how they use ICT en what the consequences for citizens are.
