On-line learning is an asynchronous computer-based learning mode that allows learners to learn anytime and anywhere in their own environment using information and communication technology. It can be considered as a way to bridge the digital gap. How a computer novice performs in such virtual and asynchronous learning environments is an interesting issue in human–computer interaction research. This paper presents the results of a study to investigate on-line learning performance and computer anxiety for unemployed adult novices. In this study, we propose a novel idea that integrates the concept of Shannon entropy into a grey relational analysis model. The proposed method was used to measure human information behavior in relation to on-line learning performance and computer anxiety. A total of 115 unemployed adults voluntarily participated in the experimental study. All experimental subjects were divided into groups according to individual differences in gender, age ranges, educational levels, and learning performances. Taking advantage of the grey relation entropy operation, we derived the perceptive correlations among different classified groups in terms of the accessibility of on-line learning and computer anxiety scales, respectively. Through the empirical study, certain on-line learning characteristics were also identified. 相似文献

Expanding computer network technologies have emerged as a popular communication channel for millions of people. Contemporary literature abounds with ideologically biased accounts of on-line interaction that hinder the emergence of a coherent analytical framework. Scholarly work on computer-mediated communicative play remains underdeveloped. Through an empirically grounded theoretical orientation, this study aims to identify and illustrate processes and elements central to the emergence of self in on-line chat environments. By use of an e-mail survey, participant observation, content analysis, and open-ended interviews, the social nature of on-line interaction is illustrated and identified as significantly more than the technological sum of the medium. Findings indicate that through on-line chat-interaction a ''cyberself'' emerges, rooted in a unique form of communication that is disembodied, dislocated, anonymous, multiple-simultaneous, and faceless. Each of these elements introduces new possibilities to the dramatic nature of on-line interaction, which represents a kind of communication ''self-game'' where participants enact a multiplicity of selves. 相似文献

The Internet has doubled in size every year in recent years and now spans the globe, facilitating the exchange of all matter of digital data. Recent development has been categorized by an explosion in new commercial activity. Despite overwhelming coverage in the popular press, relatively little is understood regarding the impact the Internet is having on firms that use this medium to facilitate commerce. Even less is understood about the impact on small enterprises-the largest segment of U.S., Japanese, and Western European businesses. This article reports the results of an exploratory study examining critical issues surrounding the use of the Internet in emerging enterprises. The survey (1) describes how small businesses develop and use their on-line sales presence, (2) explores factors that motivate firms to invest in electronic commerce, (3) assesses the importance of the expected benefits of an on-line sales presence on the decision to go on-line, and (4) examines some of the barriers that prevent small businesses from further developing their on-line presence. 相似文献

Abstract Numerous environmental forces exist today that contribute to changing industry and market segments. The least studied of these is the impact of information systems which transcend traditional company boundaries. One of the subtle impacts of contemporary developments in information systems technology is the redefinition of traditional organizational and industrial boundaries. Examples of these interorganizational systems (referred to as IOS), reviewed by the author, imply that a wide range of organizations may have an opportunity to use these systems to improve their operations, services to their customers, and their competitive position. Some of these systems raise public policy issues that are not well understood, nor are they being addressed in a comprehensive manner. This article is designed to provide a conceptual framework for thinking about these systems. 相似文献

This is a follow-up article toPhilip Brey's ``The ethics of representation andaction in Virtual Reality' (published in thisjournal in January 1999). Brey's call for moreanalysis of ethical issues of virtual reality(VR) is continued by further analyzing issuesin a specialized domain of VR – namelymulti-user environments. Several elements ofBrey's article are critiqued in order to givemore context and a framework for discussion.Issues surrounding representations ofcharacters in multi-user virtual realities aresurveyed in order to focus attention on theimportance of additional discussion andanalysis of specialized aspects of VR. 相似文献

in Internet relay chat too. Introduction Although a number of linguists such as Baron (2000), Crystal (2001) and Hillier (2004) have begun to explore and describe some of the changes in function and form of written language as a consequence of technological developments and the rise of the internet, computer mediated communication is still relatively less explored. As for the pragmatic interpretation of Internet chat, much less work has been done. This paper is a study of conversational patt… 相似文献

This article explores the roles of on-line publications in promoting ethnic communication. Through a case study of the on-line Chinese language publications, it examines the potentials of such publications in supplementing and expanding the functions of the traditional ethnic media, strengthening cultural and communal ties of the ethnic groups, and mobilizing them for action The authors argue that in the age of cyberspace, the role of ethnic media in fortifying the cultural traits of ethnic immigrants is expected to be further strengthened. As a result, ethnic groups are more likely to be assimilated into the mainstream culture without losing their own cultural roots and ethnic identity. 相似文献

This article uses a notorious incident within the computer program EVE Online to exemplify and facilitate discussion of the
metaphysics of virtual worlds and the morality of user behavior. The first section examines various frameworks used to understand
virtual worlds, and emphasizes those which recognize virtual worlds as legal contracts, as representational worlds, and as
media for communication. The second section draws on these frameworks to analyze issues of virtual theft and virtual betrayal
arising in the EVE incident. The article concludes by arguing that, in the absence of countervailing contractual obligations,
users of virtual worlds have the same de facto duties to each other as they do in mediated and real environments.
This paper grew out of my senior thesis in philosophy at Pomona College, entitled Game Theory: The Metaphysics and Morals
of Massively Multiplayer Environments. I am indebted to Peter Kung and Paul Hurley for their critical insights and constant
encouragement, as well as the Fulbright program, which afforded me the time and resources to develop this project. 相似文献

Information and communication technology (ICT) developments and trends in recent years have had great impact on the banking sector worldwide. In many developed and developing countries, the use of disruptive innovation technologies has accelerated change in the way banking business is conducted, consumers being swept along with such change. However, in many countries, such as Oman, there are deep routed cultural and religious factors that cause consumers to question the acceptance of such changes. Through the use of a theoretical framework built on technology acceptance frameworks and models, and empirical evidence from key market segments of the Omani banking market, the research explores the factors that influence Omani consumer acceptance of on-line banking. The findings are significant in that trust, usability and perceived quality are deemed key drivers. This is probably not unexpected, however, what is interesting is that the market profile is skewed to middle aged users, with social standing and “herd” mentality does not affect the adoption of the technology. This, combined with the emerging mobile savvy younger generation poses an interesting challenge for the future of the banking sector in Oman and implies a need for the sector to rethink the strategic use of, and approach to, implementation of on-line banking in a way that is complementary to the cultural and ethological dimension of the market. In effect, the banking sector will need to manage the covert tension between technology driving “fast time”, and the Omani culture, religion and tradition demanding face to face “slow time”. 相似文献
