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

Increasing concern about the release of potentially harmful chemicals into the environment has led to efforts to collect data on such chemicals with a view to identifying and minimising the associated hazards. The collection and storage of such data requires cooperation and communication (both national and international) between partners in a general environmental data network. A format is described for the exchange of data between these network partners. This format is of general applicability. It is shown that a hierarchical tree structure best describes the situation. Rules are derived to identify and process the nodes in the tree such that information is neither lost nor degraded upon transfer between the network partners. 相似文献

Positive news is advantageous for a party, but the effects ofnegative news are less obvious, especially in a multiparty system.One possibility is an indecisionmodel in which negative informationwould push voters to the undecided category. An alternativeis a proportional model in which voters would move to otherparties in proportion to their share of the vote. A third scenariowould correspond to a proximity model in which the shift wouldbe to parties holding viewpoints similar to those of the criticizedparty. The three models were tested using the ideodynamic modelor the 1994 elections in the Netherlands and Germany. The explanatoryvariables were content analysis data obtained daily for majorprint and electronic news media. The dependent variable wasweekly survey data of party preferences of voters. The analysisshowed the proportional model to be the least plausible withthe proximity model being promising. Campaign strategists startingfrom the proximity model will both promote negative news aboutother parties and adopt their issue positions. 相似文献

This article describes the reported practices in literacy assessment, recording, and reporting in 12 Australian schools characterised by populations of diverse learners. The findings indicate the problems and challenges teachers face in providing socially just and inclusive literacy assessment in heterogeneous classrooms. We make a number of suggestions related to enhancing assessment, recording, and reporting at the classroom level and argue for systemic support for teachers. 相似文献

Millions of young people who could achieve in mathematics and science are being discouraged or prevented from studying these subjects. Access to jobs, status and power in a high-tech, information economy depends upon mastery of these fields, but erroneous beliefs about aptitude are limiting the options for young women, students of color and students from poverty. Curriculum reform efforts are exciting, much-needed improvements, but the single most important change we need is a national consciousness raising. We should hold high expectations for all students and expect virtually all of them to achieve. Outdated and false notions about which groups possess the aptitude for technical subjects should not be used as barriers to access. 相似文献

The design and evaluation of the New England Head Start Teaching Center (NEHSTC), one of 14 federally funded programs created to test the efficacy of participatory, hands-on training for enhancing Head Start service delivery is the focus of this article. The unique characteristics of the NEHSTC and the outcome evaluation results from 3 years of training will be discussed. The findings demonstrate the NEHSTC was successful in implementing high quality, participatory training within the context of an ongoing Head Start program. Various Head Start staff who participated in the NEHSTC trainings demonstrated gains in knowledge, skills, and attitudes compared to similar Head Start employees who did not receive training. The positive findings suggest that participatory training should be included in the menu of training options available. Because of the unique size and scope of Head Start, the success of ongoing efforts to improve the quality of its programs and services are particularly significant. Within Head Start, this discussion of quality enhancements via innovative training models is timely given the advent of the new performance standards and the restructuring of the Training and Technical Assistance system. Additionally, the findings are relevant for broader efforts to improve early care and education programs nationwide. 相似文献
