We examined the nature and content of 150 randomly selected pornographic images available in Usenet newsgroups on the Internet in April 1994. Using content analysis, we identified themes that appear most frequently and explored differences in the type of material posted by commercial and noncommercial users. Results suggest that commercial vendors are more likely to post explicit pornographic material in public access newsgroups to attract new customers to their private, pay-per-use bulletin board services. 相似文献

This study presented an inverse chi-square based web content classification system that works along with an incremental update mechanism for incremental generation of pornographic blacklist. The proposed system, as indicated from the experimental results, can classify bilingual (English and Chinese) web pages at an average precision rate of 97.11%; while maintaining a favorably low false positive rate. Such satisfactory performance was obtained under a cost-effective parameter configuration used in inverse chi-square calculations. The proposed incremental update mechanism operates on the linking structure of pornographic hubs to locate newly added pornographic sites. The resulting blacklist has been empirically verified to be comparatively responsive to the growth dynamics of pornography sites than three public domain blacklists. 相似文献

Users of the Internet are stripped of voice inflections, body language, and other common cues of conversation-only their words are left. Some claim that the lack of these social cues and the lack of hierarchy in the structure of the Internet provide the potential for equality in cyberspace. Many others have shown, though, that the issues of power in cyberspace are similar to the issues of power in physical space. This article examines an intersection of feminism and cyberspace in the ethos of online discussion. It is a rhetorical analysis of two popular feminist newsgroups, alt.feminism and soc.feminism. Do these newsgroups create a feminist and inclusive space online? What are the rhetorical strategies that make an online space more or less inclusive of women? Usenet newsgroups reveal the rhetorical power of these bare words. Although no formal means of discrimination is built into Usenet newsgroup discussions, discrimination does occur through the subtle and not so subtle use of language. This article looks at how various characteristics of language are used on the two newsgroups. Though the ethos on such discussion forums is dynamic, the analysis reveals examples of how sarcastic questioning, strong assertions, accusatory disagreements, and sexistcomments can create a hostile and noninclusive ethos. 相似文献

Usenet is an international communications system composed of thousands of topically named discussion groups, called newsgroups, which enable anyone with an Internet connection and the proper software to read messages, post new messages, or reply to existing ones. Remarkable for its culture of 'anything-goes' free speech, Usenet tradition recognizes only one kind of legitimate restriction on content: that which is abusive to the Net's ability to function as an effective discussion system. This article shows that this consensus stems from a long and often painful struggle, as Usenet's designers, administrators, and users attempted to comprehend, define, and govern the communication system they had created. The result is a forum that is not quite as free as Usenet's defenders like to imagine, and one given to excesses that seem destined to attract the attention of government censors. 相似文献

This article examines the dynamics of centralization and decentralization of Usenet newsgroups. In doing so, it considers the similarities and differences between the organization of Usenet and the design principles for other self-organizing and self-governing common-pool resource (CPR) institutions. The rise and fall of the Backbone Cabal and the birth of the "alt" hierarchy provides insight into the early conflicts between the centralizing and decentralizing processes of Usenet. Today's procedures for group creation in the big eight hierarchies and in "alt" hierarchy and the Usenet death penalty (UDP) show that earlier tensions are still extant. 相似文献

Electronic commerce offers immense opportunities to the producers of pornographic products and services. Although this sector generates significant revenues, it is almost invisible in academic literature on the information society and the digital economy, where it is both little discussed and undertheorized. We suggest that a social shaping of technology framework may help explain current moves by stakeholders in the industry to achieve legitimacy, and that this approach may assist future analyses of commercial dynamics in the online pornography sector. 相似文献

The Web has become a worldwide source of information and a mainstream business tool. It is changing the way people conduct the daily business of their lives. As these changes are occurring, we need to understand what Web searching trends are emerging within the various global regions. What are the regional differences and trends in Web searching, if any? What is the effectiveness of Web search engines as providers of information? As part of a body of research studying these questions, we have analyzed two data sets collected from queries by mainly European users submitted to AlltheWeb.com on 6 February 2001 and 28 May 2002. AlltheWeb.com is a major and highly rated European search engine. Each data set contains approximately a million queries submitted by over 200,000 users and spans a 24-h period. This longitudinal benchmark study shows that European Web searching is evolving in certain directions. There was some decline in query length, with extremely simple queries. European search topics are broadening, with a notable percentage decline in sexual and pornographic searching. The majority of Web searchers view fewer than five Web documents, spending only seconds on a Web document. Approximately 50% of the Web documents viewed by these European users were topically relevant. We discuss the implications for Web information systems and information content providers. 相似文献

Breaking the Ivory Tower: Academic Entrepreneurship in the Life Sciences in UK and Germany 总被引：1，自引：0，他引：1
We examine engagement in commercial activities (consulting, patenting, and founding) among more than 2200 German and UK life scientists. We test hypotheses that include attributes of individuals, their material and social resources, and perceptions about values and reputation. We find that characteristics reflecting professional security, advantage and productivity are strong predictors for a greater breadth of participation in academic entrepreneurship, but not for all forms of technology transfer that we are able to test. For such academics, science and commerce go hand in hand, as they are best poised to straddle the boundary between industry and academy. We find strong support, however, that scientists perceive the value of patenting differently, and the level of reputational importance placed on scientific compared to commercial achievements matters in shaping commercial involvement. 相似文献

Media studies research in the 1990s illustrated an incongruity between cultural diversity in the Australian community and the representation of that diversity on commercial television screens. Australian drama in particular received much criticism for its seemingly 'Anglo' portrayal of Australian society. Most of this former research was based on program content analysis and critical approaches to studying the media. From the mid-1990s, anecdotal evidence suggested an improvement in the casting of actors from culturally diverse backgrounds. This paper contextualises policy and industry developments in the 1990s related to cultural diversity and presents new research undertaken within the commercial television drama industry. In order to determine the status of cultural diversity and commercial television drama at the end of the 1990s, a casting survey of all Australian commercial drama programs broadcast in 1999 was carried out. This was complemented by interviews with industry personnel and a two-week content analysis of programming. The research establishes the degree of casting for actors from culturally diverse backgrounds and offers explanations for both improvements made over the previous years and the continuing obstacles faced by some groups in gaining a place in our popular drama programs. 相似文献

In this article I examine a recent development in online communication, the immersive virtual worlds of Massively Multiplayer
Online Role-Playing Games (MMORPGs). I argue that these environments provide a distinct form of online experience from the
experience available through earlier generation forms of online communication such as newsgroups, chat rooms, email and instant
messaging. The experience available to participants in MMORPGs is founded on shared activity, while the experience of earlier
generation online communication is largely if not wholly dependent on the communication itself. This difference, I argue,
makes interaction in immersive virtual worlds such as MMORPGs relevantly similar to interaction in the physical world, and
distinguishes both physical world and immersive virtual world interaction from other forms of online communication. I argue
that to the extent that shared activity is a core element in the formation of friendships, friendships can form in immersive
virtual worlds as they do in the physical world, and that this possibility was unavailable in earlier forms of online interaction.
I do, however, note that earlier forms of online interaction are capable of sustaining friendships formed through either physical
or immersive virtual world interaction. I conclude that we cannot any longer make a sharp distinction between the physical
and the virtual world, as the characteristics of friendship are able to be developed in each. 相似文献

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others. 相似文献

On the basis of survey responses from 507 academic biomedical researchers, we examine the impact of patents on access to the knowledge and material inputs that are used in subsequent research. We observe that access to knowledge inputs is largely unaffected by patents. Accessing other researchers’ materials and/or data, such as cell lines, reagents, or unpublished information is, however, more problematic. The main factors associated with restricted access to materials and/or data include scientific competition, the cost of providing materials, a history of commercial activity on the part of the prospective supplier, and whether the material in question is itself a drug. 相似文献
