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

The authors assessed the influences of several risk factors—self‐esteem, history of unwanted sexual contact (USC), depression, and sorority membership—on eating‐related and weight‐related attitudes and behaviors. Findings provide support for the roles of self‐esteem, depression, and USC on restricting attitudes. According to the authors' model, these independent variables predicted restricting attitudes that then predicted restricting behaviors. Implications for preventive interventions and the study's limitations are discussed.  相似文献

This study compared and illustrated four differential distractor functioning (DDF) detection methods for analyzing multiple-choice items. The log-linear approach, two item response theory-model-based approaches with likelihood ratio tests, and the odds ratio approach were compared to examine the congruence among the four DDF detection methods. Data from a college-level mathematics placement test were analyzed to understand the causes of differential functioning. Results indicated some agreement among the four detection methods. To facilitate practical interpretation of the DDF results, several possible effect size measures were also obtained and compared.  相似文献

Category‐based induction is a hallmark of mature cognition; however, little is known about its origins. This study evaluated the hypothesis that category‐based induction is related to semantic development. Computational studies suggest that early on there is little differentiation among concepts, but learning and development lead to increased differentiation based on taxonomic relatedness. This study reports findings from a new task aimed to (a) examine this putative increase in semantic differentiation and (b) test whether individual differences in semantic differentiation are related to category‐based induction in 4‐ to 7‐year‐old children (N = 85). The results provide the first empirical evidence of an age‐related increase in differentiation of representations of animal concepts and suggest that category‐based induction is related to increased semantic differentiation.  相似文献

This study investigated Mexican immigrant parents’ reports of perceived workplace discrimination and their children's behavior, parents’ moods, and parent–child interactions. Parents of one hundred and thirty‐eight 3‐ to 5‐year‐old children were asked to complete one survey daily for 2 weeks (= 1,592 days). On days when fathers perceived discrimination, fathers and mothers reported more externalizing child behaviors, and mothers reported fewer positive child behaviors. When mothers perceived discrimination, they reported more externalizing child behaviors; fathers reported more internalizing child behaviors. Parents reported worse mood on days with perceived discrimination. Perceived discrimination was not strongly related to parent–child interactions. For fathers, but less so for mothers, those whose psychological acculturation indicated separation had more negative relations between daily perceived workplace discrimination and child and family outcomes.  相似文献
