We used data gathered via investigative “RoundUp” software to measure a year of online child pornography (CP) trafficking activity by U.S. computers on the Gnutella peer-to-peer network. The data include millions of observations of Internet Protocol addresses sharing known CP files, identified as such in previous law enforcement investigations. We found that 244,920 U.S. computers shared 120,418 unique known CP files on Gnutella during the study year. More than 80% of these computers shared fewer than 10 such files during the study year or shared files for fewer than 10 days. However, less than 1% of computers (n = 915) made high annual contributions to the number of known CP files available on the network (100 or more files). If law enforcement arrested the operators of these high-contribution computers and took their files offline, the number of distinct known CP files available in the P2P network could be reduced by as much as 30%. Our findings indicate widespread low level CP trafficking by U.S. computers in one peer-to-peer network, while a small percentage of computers made high contributions to the problem. However, our measures were not comprehensive and should be considered lower bounds estimates. Nonetheless, our findings show that data can be systematically gathered and analyzed to develop an empirical grasp of the scope and characteristics of CP trafficking on peer-to-peer networks. Such measurements can be used to combat the problem. Further, investigative software tools can be used strategically to help law enforcement prioritize investigations. 相似文献

It is well known that having a chronic or traumatic health condition can seriously impact on a young person’s educational trajectory, as well as placing the young person at higher risk of experiencing mental health conditions such as depression and anxiety, and increasing their likelihood of participation in risky behaviours. This paper reports on research examining best practice by schools in mitigating the impact of having a health condition by keeping students engaged with education in the post-compulsory years of schooling. The research project was designed to examine the strategies, both formal and informal, which are enacted by schools, individual teachers, families and students in ensuring an ongoing connection with educational pathways in the senior years. We describe an interconnected set of critical success factors for retaining these vulnerable young people in education, and reflect on the implications of these for educational policymakers and school administrators. 相似文献

This paper describes research which investigated how a group of 23 postgraduate student teachers from a wide variety of international backgrounds with a broad range of previous experience perceived the significance of their own and others’ prior experience in accomplishing directed collaborative tasks, related to their coursework, in pre-determined groupings. The students were asked to comment on how they valued their own and others’ prior experiences and how they considered prior experience informed the completion of the tasks. They were also asked to comment on the dynamic of groups in which they worked and how they felt others’ prior experiences affected the management and achievement of the task. The students rated some experiences more highly than others and almost all appreciated the predetermined nature of the groupings as benefitting them socially as well as educationally. However, they raised practical, attitudinal and personality issues, suggesting that more structured guidance from tutors at the outset would be beneficial. 相似文献

Abstract This paper presents the findings of a one‐year (2002–2003) action research project conducted in a representative number of post‐primary schools across the sectarian divide in Belfast. The research investigated the responses of sixth‐form students to a number of carefully chosen texts focused on ‘The Troubles’. In analysing the pupils’ responses, it was discovered that, although inherited sectarian tensions persist, it is possible in many cases to encourage pupils to critically examine their attitudes and even abandon some prejudices. The key elements are the choice of texts and the need to provide ample and skilfully directed opportunity for dialogue and reflection. These findings are particularly relevant in the current climate of curriculum change, with the new emphasis on ‘diversity’ as well as ‘local and global citizenship’. 相似文献

ABSTRACT The model replacing a dedicated off-campus library services (OCLS) unit was one in which librarians provide services to both on- and off-campus students and faculty within their liaison disciplines. A year after this model was implemented, faculty in subjects taught both on- and off-campus were surveyed to assess their awareness of library resources and whether this awareness impacted course assignment design. Findings from this survey combined with a planned review of off-campus course syllabi will help identify areas of concern and lead to ways to strengthen awareness and usage of library resources. 相似文献

The New Information Poor: How Limited Access to Digital Scholarly Resources Impacts Higher Education
The “new” information poor are the individuals and communities who have computer and Internet connectivity, but cannot access scholarly information due to prohibitive costs. Pratt Institute's School of Information and Library Science (SILS) represents such a community and is the subject of this case study. Three measures were analyzed: SILS' four “core” classes were surveyed to determine how many required readings were available via the library; a survey was sent to 31 SILS instructors; and we conducted in-depth interviews with two SILS instructors. While “information poor,” the data suggest our respondents are resourceful in finding ways to cope with their disadvantage. 相似文献

Information quality and community municipal portal use 总被引:1,自引:0,他引:1
This paper presents an in-depth research investigation of the role information quality plays in the use of community municipal portals. These portals are a new type of website spearheaded by local governments and community agencies in response to citizen calls for a more user-friendly, comprehensive, and convenient way of accessing community-based and local government information via a single entry point. Prior empirical evidence on electronic government adoption and use shapes the study's theoretical model. The model was tested via a survey completed by 1279 respondents across five community municipal portal sites in the province of Ontario, Canada. The survey polled respondents' uptake and perceptions of these portals. Cross-validation using structural equation modeling analysis indicates that information quality plays a critical but indirect role in influencing a person's use of a community municipal portal. In addition, other end-user factors, namely perceived ease of use and compatibility, also affect usage. Importantly, the need to pay attention to the information quality of community municipal portals is raised as a means of rallying citizen response to this new type of website specifically, as well as to local government websites more generally. 相似文献

This study tested whether a screening procedure was effective in the treatments for communication apprehension (CA). Accordingly, individuals who were identified as having cognitive, affective, and behavioral source of CA were exposed to Visualization (cognitive). Systematic Desensitization (affective). Skills Training (behavioral), and Multiple treatment (combination of the three). Results indicated that exposing people to the matching intervention was slightly more effective in reducing CA than exposing them to other treatments. 相似文献
