Sex determination is a key analysis that forensic anthropologists perform in order to construct a biological profile of human remains. The techniques used in forensic investigations must meet the Mohan or Daubert criteria, for admissibility in a court of law. In this study, the precision and accuracy of 21 morphological characteristics of the skull were tested on a modern sample of 50 adult crania of European White ancestry. The following craniofacial features are identified as high-quality traits, defined by intraobserver error or=80%: mastoid size, supraorbital ridge size, general size and architecture, rugosity of the zygomatic extension, size and shape of the nasal aperture, and gonial angle. Ninety-six percent accuracy and 92% precision were achieved using 20 traits in combination. Fisher's exact probability tests revealed no significant differences (p=0.05) in the levels of precision or accuracy between age categories. Sex-related bias in accuracy was found for the following cranial features: ramus symphysis (p=0.009), zygomatic extension (p=0.0016), and occipital markings (p=0.0013). These traits demonstrated a greater tendency to be scored male than female. 相似文献

Purpose
This article provides a critical review of the state of research on the gang membership-violent victimization relationship.Methods
This study examines a comprehensive list of published quantitative studies that have assessed the relationship between gang membership and violent victimization.Results
By examining strengths and weaknesses of the design features of various studies, this article identifies theoretical, conceptual, methodological, and statistical issues that should be considered when interpreting the causal effect of gang membership on violent victimization. Some of the methodological and design issues discussed include, but are not limited to, consequences of failing to establish temporal order, failure to conduct sensitivity analyses to determine treatment effects, use of bootstrapping methods with propensity score analysis, measurement of violent victimization, and corrections for dependence in matched samples of gang and non-gang members.Conclusion
Suggestions for future research are provided that will help advance the empirical study of the gang membership-violent victimization nexus. 相似文献76.

Purpose
This study examines whether a problem-oriented approach used by police in Cincinnati, Ohio called the Crash Analysis Reduction Strategy (CARS) corresponded with a change in the number of traffic crashes that resulted in injuries after implementation onset. Under the CARS model, police developed tactics that focused on targeting high-risk driving behaviors, impaired drivers, and crash hotspot locations within the city.Methods
Using a two-phase strategy we first assess local impact by examining injury-related traffic crash patterns at targeted locations. Second, we examine whether traffic crashes that resulted in injuries in Cincinnati significantly diverged relative to similar outcomes across a number of comparison sites.Results
Difference-in-difference negative binomial regression analyses indicates that traffic crashes were significantly lower in Cincinnati - down roughly 5.7% to 10.3% in the post-intervention period - when contrasted with comparison sites.Conclusions
Our findings suggest that comprehensive problem solving approaches can significantly reduce the risk of life changing events such as automobile crashes that result in injuries beyond traditional policing efforts that explicitly focus on crime and violence. 相似文献77.

Purpose
Extant scholarship has examined pornography's putative link to the commission of sex crime. Yet, virtually no research speaks to whether an offender's exposure to pornography during many different stages of life elevates the violence of a sex offense. The current study addresses this gap.Methods
Using retrospective longitudinal data, we systematically investigate the effect of offender pornography exposure during adolescence, adulthood, and immediately prior to the offense on the level of physical injury as well as the extent of humiliation experienced by sex crime victims.Results
Findings indicate that adolescent exposure was a significant predictor of the elevation of violence—it increased the extent of victim humiliation. Results also suggest a tempering, or cathartic effect of pornography—using pornography just prior to the offense was correlated with reduced victim physical injury. No effects, however, were observed for adult pornography exposure.Conclusion
Pornography use may differentially influence offenders’ propensity to harm or degrade victims over the life course. 相似文献78.
Purpose
Disproportionate minority contact during traffic stops has been a consistent source of commentary and study in recent years. While various theoretical perspectives have been employed to explain these empirical findings, the differential offending hypotheses has been largely ignored as a viable alternative explanation. Building on existing empirical evidence regarding criminal offending patterns and driving patterns, we examined the veracity of this explanation using data from an observational study of urban driving behavior.Methods
Data were collected using an observational methodology in an urban environment. These data were then used to estimate various regression models and test the differential offending hypothesis.Results
Analytic models indicated that Black drivers speed more frequently and engage in more severe speeding compared to White drivers, net of controls.Conclusions
The findings suggest that citizen risk for specific police behavior is partially attributable to differential behavior prior to the encounter. These results mirror the findings of previous research in other geographic locations using different methodologies; thus, contributing to the conclusion that understanding officer decision-making and behavior requires consideration of other factors beyond a citizen's race. 相似文献79.
This article offers a conceptual exploration of the changing notion of trust and distrust in today's news media ecology. Central is the question whether the relationship between the traditional media actors, media organisations, journalists and news users, can be increasingly characterised by distrust. Do we really notice a decline in trust in the news media? And moreover, are these feelings of distrust grounded? In order to answer these questions, we look at the changing economic, technological and societal context and how this might explain the strained relationship between these actors. We find that to a large extent the goals of the media actors diverge or even conflict. Mutually bridging these goals is difficult as they boil down to ideological and normative choices. This requires us to reconsider our ways of looking at trust. Therefore, this article's central argument is that a trusted relationship between the media actors is unlikely to result from a definitive settlement between the actor's conflicting goals. Rather, maintaining a trusted relationship is likely to become a matter of constant renegotiation. For this renegotiation to succeed, transparency and integrity are key. We find inspiration in the recent work of Solove (2001), Nissenbaum (2004) and Mansell (2008, forthcoming) to take a different, more contextual approach towards the notion of trust. As regards the relationship between news organisations and users, we suggest these norms should be negotiated in a balanced and transparent way, giving users an equal say in the process. The relationship between journalists and news users should be guided by a mutual interest in truth telling, whereby users are not only merely seen as consumers, but also as potential contributors to news stories. Policy makers in turn should act as facilitators of such spaces of renegotiation. 相似文献

The aim of this paper is two-fold: first, to introduce how Japanese law and its jurisprudence have dealt with the case of on-line defamation, which is arguably one of the most acute problems in modern society, and second, to critically examine the efficacy of such an approach. The recent decision of the Supreme Court in on-line defamation (as oppose to off-line defamation) will be introduced as an exemplar of the way Japanese law and its jurisprudence have dealt with such an acute problem. A first step will be to provide, by way of background, a brief overview of how defamation in a conventional sense has been treated by the Japanese legal system. The second step will be to outline how the Japanese jurisdiction has dealt with on-line defamation, that is to say, to what extent the Japanese court regulates on-line defamatory comments made by the ordinary people. A third step will be to examine the efficacy of such an approach, and the final step will be to examine whether the UK court can learn a lesson from the Japanese jurisdiction. The author will draw upon Japanese jurisprudence, in order to consider whether a valuable lesson might be offered to the UK jurisdiction. 相似文献
