Traditional economic theorists have argued that services in general, and public services in particular, are unproductive and parasitic. Data is presented from seven representative countries at varying levels of economic development to show that, in fact, services are productive and play a critical role both in enabling the production of goods and In ensuring quality of life.  相似文献

This study explores the relationship between mothers' approval of corporal punishment and the degree to which they themselves were subjected to violence as children. Considered as additional contributing factors are: (1) whether the mothers as children were punished by their own parents, (2) whether they perceived such punishment as unfair, and (3) the degree of parental nurture they experienced as children. The sample consisted of 330 new mothers whose mother and father both lived in the home when they were 14 years of age. Respondents were interviewed at home one to two months following their infants' discharge from the hospital. After controlling for race and income, no relationship was found between approval of corporal punishment and the violence to which mothers were subjected as children. However, significant associations were found between such approval and: (1) whether mothers were punished by their parents, and (2) maternal (but not paternal) nurture. Perceptions that parental punishment was unfair failed to contribute to such approval. Altogether, parental factors in mothers' childhoods, excluding race and income, accounted for 8.9% of the variance in approval of corporal punishment.  相似文献

Recent developments in biotechnology are radically affecting the nature of reproduction and the manner in which we approach disease. In particular, germline gene therapy, or the insertion of genetic material into cells while they are developing and dividing, offers the promise of eradicating genetic defects in humans during embryonic development. In this article, the authors argue that the social and ethical implications of the developments in the field of germline gene therapy have not yet received adequate consideration. Unlike previous technologies which targeted already-developed cells, germline gene therapy can potentially correct and eliminate genetic deficiencies at the developmental stages of a cell. This raises issues of genetic enhancement beyond the therapeutic applications of this technology. However, the authors submit that an established pattern of subordinating social and ethical issues to technical and scientific debate in the regulatory arena is repeating itself in the case of discussions over germline gene therapy. The authors suggest that the American scientific regulatory process fails to fully meet the challenges of this technology, particularly because social and ethical issues are not formally considered in the existing process. They therefore suggest that American regulatory agencies should look to the approach taken by Europe with regard to germline gene therapy as an emerging technology, and that it may be necessary to incorporate effective public debate over social and ethical concerns into a regulatory process which is primarily concerned only with the efficacy of new technologies.  相似文献

Conclusion In this paper we have undertaken what we regard as a preliminary critique of the concept of social control and its utility for a critical criminology in Canada. In tracing its emergence and historical development as a key concept in American sociology, we have illustrated that its ascendancy represented a victory for liberal sociology. The recent attempts by critical criminologists and sociologists to rehabilitate the concept of social control by insisting upon the essentially coercive nature of control have not resulted in an advance over traditional theorizing.By examining the women, law and social control literature, in particular the use of the formal/informal dichotomy, we have attempted to illustrate the limited utility of the concept for developing an historically and theoretically informed understanding of the complex and contradictory relationship of women to the state and law. The concept of social control is ahistorical: when coupled with law, moreover, it lends itself to instrumentalism. It is our view that the concept of social control ought to be abandoned by critical scholars in favour of one attentive to the dynamic complexity of history, struggle and change.Paper presented at the Annual Meeting of the Canadian Association of Sociology and Anthropology, 4–7 June 1986, Winnipeg, Manitoba.

Research indicates that insecurely-attached adolescents are at risk for depression, but little is known about factors that may influence or explain this vulnerability. The present study focuses on close relationships during adolescence and their association with depression. Specifically, the objectives were to investigate (1) the role of working models of specific attachment figures (i.e., mother, father, best friend, and romantic partner) in the prediction of depression; and (2) the existence of target-specific pathways to depression following relational stress. It was expected that the paths to depression would differ depending on the attachment figure under consideration. A total of 134 adolescents (n = 88 girls; Mage = 16.95 years; SD = .74) completed attachment questionnaires, a depression inventory, and a computer task consisting of hypothetical interpersonal vignettes and questions. Insecure attachment relationships with romantic partner, and for girls only, with mother, were uniquely predictive of depression. Insecurely-attached adolescents' tendency to make negative attributions in response to stresses fully mediated the attachment–depression association. These adolescents were found to ruminate when confronted with stresses involving romantic partner, which was also associated with depression. Results underscore the link between attachment, negative attributions, and depression. Staff Psychologist, Child Psychiatry Department at the Jewish General Hospital.

Video data received for analysis often come in a variety of file formats and compression schemes. These data are often transcoded to a consistent file format for forensic examination and/or ingesting into a video analytic system. The file format often requested is an MP4 file format. The MP4 file format is a very common and a universally accepted file format. The practical application of this transcoding process, across the analytical community, has generated differences in video quality. This study sought to explore possible origins of the differences and assist the practitioner by defining minimum recommendations to ensure that quality of the video data is maintained through the transcoding process. This study sought to generate real world data by asking participants to transcode provided video files to an MP4 file format using programs they would typically utilize to perform this task. The transcoded results were evaluated based on measurable metrics of quality. As the results were analyzed, determining why these differences might have occurred became less about a particular software application and more about the settings employed by the practitioner or of the capabilities of the program. This study supports the need for any video examiner who is transcoding video data to be cognizant of the settings utilized by the programs employed for transcoding video data, as loss of video quality can affect analytics as well as further analysis.  相似文献

Research indicates that social support plays a protective role among adolescents, but little research has explicitly evaluated its function among youth involved in bullying. Accordingly, this study examined relations among social support, bully/victim status, and psychological distress in a sample of 784 ethnically diverse youth. We assessed differences in perceived social support across bully/victim subtypes, and evaluated peer and maternal social support as protective factors among victims, bullies, and bully-victims. Youth were classified as uninvolved (61.6%), as bullies (14.3%), as victims (12.5%), and as bully-victims (11.6%). Uninvolved youth reported the most peer and maternal social support and the least anxiety/depression. Multivariate analyses revealed that there was a significant interaction between bully/victim groups and peer social support. Specifically, bullies, victims, and bully-victims who reported moderate peer social support also indicated the least anxiety/depression. Results highlight the importance of encouraging youth to develop and effectively use peer support networks as part of bullying intervention programs.
