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.

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

Validation of Tool Mark Comparisons Obtained Using a Quantitative,Comparative, Statistical Algorithm

Abstract: A statistical analysis and computational algorithm for comparing pairs of tool marks via profilometry data is described. Empirical validation of the method is established through experiments based on tool marks made at selected fixed angles from 50 sequentially manufactured screwdriver tips. Results obtained from three different comparison scenarios are presented and are in agreement with experiential knowledge possessed by practicing examiners. Further comparisons between scores produced by the algorithm and visual assessments of the same tool mark pairs by professional tool mark examiners in a blind study in general show good agreement between the algorithm and human experts. In specific instances where the algorithm had difficulty in assessing a particular comparison pair, results obtained during the collaborative study with professional examiners suggest ways in which algorithm performance may be improved. It is concluded that the addition of contextual information when inputting data into the algorithm should result in better performance. 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.

AbstractWhen feminism informs and shapes social scientific thinking, it often yields strongly applied perspectives. The business of engaging in the application, however, presents challenges to both feminist practice and the academic disciplines. These issues are further complicated when they are played out in an interdisciplinary setting. I offer a personal reflection on the highly ambiguous situation in a part of what has been called the ‘diaspora’ of social sciences practiced not within any particular ‘home’ discipline, but in a particular sub-field or inter-discipline such as urban studies, criminology or—in this case—population health. The emphasis in this discussion is on the mutual influences of the academic and the applied. 相似文献
