The Internet offers new opportunities for anonymous and pseudonymous communications. Users can, for example, engage in political advocacy, receive counseling, and perform commercial transactions without disclosing their identities. The cloak of anonymity can also facilitate socially unacceptable or criminal activities because of the difficulty in holding anonymous users accountable. This article reports the results of a conference on anonymous communication organized by the American Association for the Advancement of Science. Among the findings were that online anonymous communication is morally neutral; that it should be considered a strong human and constitutional right; that online communities should be allowed to set their own policies on the use of anonymous communication; and that individuals should be informed about the extent to which their identity is disclosed online. The article discusses how anonymous communications can be shaped by the law, education, and public awareness, and highlights the importance of involving all affected interests in policy development.  相似文献

We assessed relations between early temperament and behavior problems across 12 years in an unselected sample of over 800 children. Temperament measures were drawn from behavior ratings made by examiners who observed children at ages 3, 5, 7, and 9. Factor analyses revealed 3 dimensions at each age: Lack of Control, Approach, and Sluggishness . Temperament dimensions at ages 3 and 5 were correlated in theoretically coherent ways with behavior problems that were independently evaluated by parents and teachers at ages 9 and 11, and by parents at ages 13 and 15. Lack of Control was more strongly associated with later externalizing behavior problems than with internalizing problems; Approach was associated with fewer internalizing problems among boys; and Sluggishness was weakly associated with both anxiety and inattention, especially among girls. Lack of Control and Sluggishness were also associated with fewer adolescent competencies. These results suggest that early temperament may have predictive specificity for the development of later psychopathology.  相似文献

This study investigates whether educators’ cognitive and structural social capital is associated with perceptions of innovative climate in charter schools. We explore a new concept to assess educators’ cognitive social capital, namely network intentionality, meaning the extent to which an educator is intentional in connecting and interacting with others. We hypothesize that network intentionality (cognitive social capital) is related to the extent to which educators perceive their school’s climate to be innovative, but that this relationship is dependent on the educator’s position in their school’s social network (structural social capital). Findings suggest that the relationship between cognitive social capital and perceptions of innovative climate is partly mediated by structural social capital. In other words, those educators with high network intentionality, as evidenced by an orientation towards connecting others, also perceive the school’s climate as being more innovative, partly because this strong network intentionality is associated with more out-going relational activity. This work provides unique insights into the factors that may be associated with teacher collaboration in successful charter schools serving traditionally underserved populations, and suggests ideas for schools wishing to support teacher collaboration and innovation.  相似文献

This article investigates the relationship of learning and its infrastructure using Web 2.0 technologies to facilitate the acquisition of skills needed to succeed in a global economy. We explore the learning phenomenon as a way to bring forward a process of continuous improvement supported by social software. We use a commonly accepted definition of learning to evaluate different learning theories, since it seems that the definition of learning itself is not a major source of difference between learning theories. Their differences are over issues of interpretation, not over definition. The theories reviewed are used in the design of a framework to assess the infrastructure against expectations of skill proficiency using Web 2.0 tools, i.e., wikis, blogs, social bookmarking, tagging, etc. which must emerge as a result of registering in an introduction to business information and communication technologies (ICT) course in a Canadian university. In this course, we use Friedman’s (The world is flat: a brief history of the twenty-first century release 3.0, Picador, New York, 2007) thesis that the “world is flat” to discuss issues of globalization and the role of ICT. Students registered in the course are usually familiar with some of the tools we introduce and use in the course. The students are members of Facebook or MySpace, regularly check YouTube, and use Wikipedia in their studies. These tools are the tools to socialize. In our course, we broaden the students’ horizons and explore the potential business benefits of such tools and empower the students to use Web 2.0 technologies within a business context.  相似文献

Previous work on female participation in Australian Rules football has highlighted the seemingly discontinuous character of the women's game as it spread from Western Australia to Victoria during the period of the Great War. In this paper, an overview of the current literature on the topic is provided, and there is a focus on hitherto ‘missing links’ in the existing sequence of events – the knowledge of which has the potential to create a more integrated narrative of the code. In particular, the photographic, filmic and textual evidence for matches of women's football played in South Australia during the Great War is discussed. These games, with proceeds directed to such charities as the ‘Workers' Memorial Fund’ as well as ‘comforts for the Anzacs’, attracted sizeable crowds and were sometimes played under the patronage of the governor of the state, the mayor of Adelaide and senior military officers. The paper concludes with a reflection on how the availability (or unavailability) of particular digitised sources, and the serendipitous nature of research itself, can have a problematic influence on investigations associated with marginalised sports such as women's football.  相似文献
