Over a decade after Napster’s introduction, file sharing programs still shoulder much of the blame for music and other media’s declining sales. Although labels and industry associations point their fingers at the harm digital piracy and file-sharing cause, they are less likely to admit the extent to which these anti-markets inform everyday decisions. File-sharing technologies create networks of users that serve as profitable data for ratings and metrics agencies. Using a case study of BigChampagne and its relationship to Napster, this article considers how the look, structure, and function of file-sharing software helped turn an economically threatening community into a commodity and how piracy’s disruptive potential is always in tension with processes of commodification. 相似文献

Drawing on the findings of a recent national survey, this article examines the extent to which higher education institutions in the United Kingdom meet the minimum standards recommended by the Health and Safety Executive (HSE) for the management of work‐related stressors. A comparison is also made between the average weekly working hours reported in the current survey with those found in two previous studies of the higher education sector (1998 and 2004). A sample of 9,740 academic and academic‐related employees working in higher education institutions in the UK completed a measure of seven job‐related stressors (or psychosocial hazards) (that is, demands, control, support from colleagues and managers, interpersonal relationships, role clarity and involvement in organisational change). With one exception (job control), levels of job‐related stressors in the higher education sector exceeded the benchmarks stipulated by the HSE. Stressors relating to change, role, job demands and managerial support were particularly high. Recommendations made by the HSE for interim and longer‐term targets to be achieved for the management of each stressor category are provided. Findings also revealed that average working hours remain high in the sector, with many employees continuing to exceed the weekly limit set by the UK Working Time Directive. The utility of the HSE approach in higher education institutions and ways in which the sector might work towards meeting the HSE management standards and consequently enhance employee well‐being are considered. 相似文献

The engagement of teachers as raters to score constructed response items on assessments of student learning is widely claimed to be a valuable vehicle for professional development. This paper examines the evidence behind those claims from several sources, including research and reports over the past two decades, information from a dozen state educational agencies regarding past and ongoing involvement of teachers in scoring‐related activities as of 2001, and interviews with educators who served a decade or more ago for one state's innovative performance assessment program. That evidence reveals that the impact of scoring experience on teachers is more provisional and nuanced than has been suggested. The author identifies possible issues and implications associated with attempts to distill meaningful skills and knowledge from hand‐scoring training and practice, along with other forms of teacher involvement in assessment development and implementation. The paper concludes with a series of research questions that—based on current and proposed practice for the coming decade—seem to the author to require the most immediate attention. 相似文献

A rapid survey of the key current issues and changes in the copyright and licensing environment. Briefly discusses the reasons why there is so much change, and in particular the changing attitudes of both authors and customers towards publishers. Surveys the new contractual problems confronting publishers; the requirements for doing business electronically in future; major legal changes; and developments in licensing. Concludes by considering how publishers can influence what happens. 相似文献
