This study reports the results of a survey conducted at Aligarh Muslim University (AMU) to determine the extent to which Internet users are aware and make use of the Internet resources and services. The study examines the information searching behavior of Internet users. A questionnaire and follow-up interviews with the postgraduate students, research scholars and academic staff were conducted to collect data. A total of 489 questionnaires were distributed to the selected sample of eight faculties; 405 valid samples were collected. The data were analyzed according to the background of Internet users, Internet information searching behavior, use of Internet resources and services, quality of Internet information, problems of the Internet access and need for Internet literacy. The study found that the majority of respondents had a 5 year history of Internet access. The academic staff spent more time on the Internet than the students and research scholars. Although Internet search engines were the preferred information searching tool, other methods such as databases, gateways and World Wide Web (WWW) were also used. Online journals and databases were the preferred information sources among the Internet users. Respondents chose e-mail, WWW and search engines as important Internet services. About 60% of respondents believed that the good quality of information on the Internet made it a useful tool for education and research. Slow speed, lack of training and information overload were indicated as some of the factors affecting Internet usage. Further, recommendations are made to improve the use of Internet, including a well-planned Internet literacy program and preparation of subject gateways. 相似文献

Faculty members from a college in a major university were surveyed to explore the possible relationship between Internet usage and the following dependent variables: computer usage (length of time and perceived expertise), length of time of Internet use, perceived expertise of Internet use, and perceived utility of the Internet. Ninety-seven percent of faculty members have an Internet account. Furthermore, computer literacy and the time one has used computers are correlated with early adoption of the Internet, perceived utility of the Internet is correlated with computer literacy and with Internet usage, and Internet use is correlated with perceived Internet expertise but not with the length of time the faculty member has used the Internet. Highly skilled computer users are more likely to use the network in a more intensive way and have higher appreciation of the network's potential. 相似文献

The current research posits that education leads to differential levels of Internet engagement, which moderate the association between Internet use for health information and general health knowledge. Using a nationally representative survey that covers adults between the ages of 40 and 70 in the United States, it is found that education is positively related to Internet engagement. Also, Internet use has stronger associations with health knowledge for people exhibiting high Internet engagement than for people exhibiting low Internet engagement. The implications of these findings for research on both Internet use and knowledge gaps are discussed. 相似文献

This study tested competing predictions about the implications of Internet use for traditional inequities in social support availability. Using survey data collected as part of the Pew Internet and American Life Project, inequities in social support availability stemming from demographic and network-related factors were examined among non-users, Internet users, and Internet users who also participated in a social network site (SNS). The results offered evidence consistent with the social compensation perspective. Traditional inequities in support availability related to age, race, and total network size persisted among respondents who did not use the Internet, but were less evident or absent among Internet users and/or Internet users who participated in an SNS. Using the Internet to connect with others appeared to be an important mechanism through which inequality in support availability was mitigated. 相似文献

Internet diffusion is not homogeneous and depends on many factors. This study uses data from the Canadian Internet Use Survey (CIUS) to explore the extent demographic variables affect Internet use by individuals in Canada. A logistic model confirms that certain factors, educational attainment, and geography in particular influence Internet use in Canada, controlling for age and income. Education maintains a strong, significant impact on Internet use such that the odds of using the Internet are about three times greater for someone who has some post-secondary education than someone who has, at most, a high school education. An urban–rural digital divide persists in Canada with the odds of using the Internet being almost one-and-a-half times greater for someone who lives in an urban area. While language also has a large effect on Internet use, the presence of children in households no longer seems to be a significant factor. This study thus underscores the changing digital environment in Canada and the need for adaptive, flexible policies addressing national connectivity issues and, in particular, broadband Internet availability. 相似文献

This longitudinal study, carried out between November 1993 and 1998, investigated the reasons that adult learners in Iceland gave for wanting to learn about the Internet, and their attitudes to it. Data were collected through a short open-ended electronic mail survey delivered to participants in Internet training courses held in Iceland over a three-year period. The authors describe the three stages in the research: identification of elements of an analytical framework; testing of a behavioral intention model of Internet use based on the theory of planned behavior; and use of the model to identify attitudes to the Internet, social influences on Internet use, perceived control of Internet use, and changes in these factors as the Internet became more widely known. They observed that learners' intended uses of the Internet became more specific between 1994 and 1996. While the influence of the media and the general community increased in this period, attitudes remained relatively stable. Participants found the Internet interesting and useful, with positive advantages over other media. They were positively disposed toward it as a source of information. For some, use was constrained by perceptions that they needed to have more knowledge or understanding in order to use the Internet better. 相似文献
