Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents.  相似文献

This paper examines the reliability of Structure from Motion (SfM) photogrammetry as a tool in the capture of forensic footwear marks. This is applicable to photogrammetry freeware DigTrace but is equally relevant to other SfM solutions. SfM simply requires a digital camera, a scale bar, and a selection of oblique photographs of the trace in question taken at the scene. The output is a digital three-dimensional point cloud of the surface and any plastic trace thereon. The first section of this paper examines the reliability of photogrammetry to capture the same data when repeatedly used on one impression, while the second part assesses the impact of varying cameras. Using cloud to cloud comparisons that measure the distance between two-point clouds, we assess the variability between models. The results highlight how little variability is evident and therefore speak to the accuracy and consistency of such techniques in the capture of three-dimensional traces. Using this method, 3D footwear impressions can, in many substrates, be collected with a repeatability of 97% with any variation between models less than ~0.5 mm.  相似文献

This article uses social media network analysis (SMNA) to examine whether there was an astroturfing campaign on Twitter in support of the Adani Carmichael coal mine in 2017. It shows that SMNA can be used to visualize and analyze outsider lobbying activity in issue arenas and is capable of identifying networks of fake opinion. This study found that in April 2017, there was a small network of accounts that made a series of suspiciously similar pro‐Adani tweets that could be considered a form of duplicitous lobbying. However, this study concludes that these posts were likely a weak influence on public opinion in Australia and largely ineffectual as a lobbying tactic. Nevertheless, this analysis shows how communitas public interests can be subverted by covert social media campaigns used in support of corporatas goals, as well as the role digital research methods can play in protecting the integrity on public debates by exposing disingenuous actors.  相似文献

In jurisdictions across the country, sexual assault kits (SAKs) have not been consistently submitted for testing and many cities are now submitting large quantities of SAKs for forensic DNA testing. As a result, some survivors will be asked to re-engage with the criminal justice system, a process that may raise complex issues for victims who were adolescents at the time of their assaults. The authors examine the experiences of 15 adolescent victims whose SAKs were not tested, and their decision-making pathways regarding reengagement with the criminal justice system years after the initial investigation. Findings reveal that characteristics of the initial assault, victim-blaming experiences, and the social support appear to be related to the decision to re-engage with law enforcement years after the initial assault. Implications for future research and practice are discussed.  相似文献
