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

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 article is an account of a Usenet newsgroup whose participants, in response to a perceived 'invasion' of 'barbarians,' explored and articulated the value of the group, the nature of the crisis facing it, and the strategies available to meet the crisis. The newsgroup facilitated political and personal support for some gay, lesbian, or bisexual men and women. The primary threat to the group was the increasing number of newcomers who were oblivious to established norms, who tended to view access to the group as a commodity, and who attempted to impose 'outside' paradigms on the operations of the group. Defensive strategies involved calling on rhetorical devices (such as flaming or ostracism) or structural resources (such as employers, network operators, or lawsuits). All strategies had the potential to backfire, but rhetorical strategies were less risky, more available, and more community affirming than strategies requiring access to structural resources. Through this account, the article addresses the mutual linkages and dependencies between the social and technical organization of computer-mediated communication (CMC) networks, the community-building activities taking place through those networks, and the social, legal, and economic structures in which those networks are embedded.  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

Organizational culture and intellectual capital (IC) have been important topics in the current organizational literature. However, few studies have analysed the correlations between these constructs. From this evidence, the main goal of the present study is to examine the correlation between the perceptions of organizational culture and the perception of IC measures. A sample consisting of 401 workers from the technological, health and services sector responded to the Organizational Culture Assessment Instrument and the Intellectual Capital Scale. Results show that the Competing Values Framework dimensions (clan, adhocracy, hierarchy and market cultures) are correlated with the three IC dimensions studied (customer, structural and human capital). Our results also show that the culture explained variance varies across organizational sectors. The current study provides an initial contribution to the investigation of the correlation between perceived organizational culture and IC measures. The discussion and analysis ends with an integrated framework with practical implications for management, followed by suggestions and guidelines for future studies.  相似文献

Studies addressing the connections between knowledge and organization structures can be divided into two classes. One class holds that a perspective on knowledge signals shortcomings of classical design principles and calls for flatter hierarchy and less specification of the production structure. Another class maintains that a knowledge perspective on organizations is at odds with any design perspective, whether classical or not, because the emergent, thoroughly social and practice-based nature of knowledge as knowing in action makes knowledge a useless and even dangerous beacon to designers: ex ante, knowledge is said to be fundamentally indeterminate and any attempt to ‘structure around knowledge’ may effectively drive out knowledge. To explore differences and possible bridges between these two calls of studies, the paper explores how both elements of the equation, organization structure and organizational knowledge, are to be conceived to ensure a meaningful connection between them. It is argued that the grouping focus in both defines the meeting place of organization structures and organizational knowledge, but shows that the involved knowledge and grouping concepts are not mutually compatible. It leads to a view where organization structures are seen as the ‘seeding’ background for knowledge integration processes that, in turn, constitute the patterns of work relationships envisioned in the designer's organizational decomposition and grouping. For illustration purposes, the paper presents the example of the Max Planck Institute that describes one possible way through the conceptual model presented in the paper.  相似文献

Although some researches had submitted the hierarchical model of customer value, there are still questions remaining in the model. How to achieve a more effective method for obtaining and analyzing data from customers concerning their expectations is still lacking. Therefore, this research first applied the modification of the means-end chain (MEC) to construct a hierarchy framework of customer value to allow product attributes to be linked. Next, this research combined fuzzy analytic network process (FANP) in exploring customer preference to catch the multiple needs of customers. Meanwhile, in the measurement of customer preference, fuzzy logic and linguistic variables are utilized to overcome human subjective and imprecise thinking. Overall, this research proposes the hierarchy framework of customer value including the causal relationships of attributes–consequence–value to fill previous model's gap, and identified the factors which could enhance the value of bundle, in contrast to the many monetary research treatments of product bundles. Finally, this research presented the value implications of cosmetics bundles and implication for management and marketing.  相似文献

We argue for a discursive ethic of surveillancethat accounts for the paradoxes that thephenomenon presents to today's organisationalmembers. We first we develop a genealogy ofprivacy and illustrate its relation tosurveillance, focusing on the antinomianrelationship between the public and private. Then we review the common ethicaltensions that arise in today's technologicallyintensive workplace. Lastly, we develop acritical approach to the ethical status ofprivacy and surveillance – a micro-ethics – that remains open todiscursively-based negotiation by those whofind themselves at the verypoint of scrutiny.  相似文献
