This study reported the impact of digital photographic evidence on domestic violence case outcomes in two Indiana counties. It analyzed whether outcomes differed between cases with digital photographic evidence (treatment group) and cases with no photographic evidence (comparison group). Examined impacts included guilty pleas, convictions, and sentence severity. Data included in the analysis came from case files and police and prosecutor interviews. Findings suggest that digital photographic evidence can be a useful prosecutorial tool – treatment group members were more likely to plead guilty, be convicted, and receive more severe sentences. 相似文献

Biological fluid identification is an important facet of evidence examination in forensic laboratories worldwide. While identifying bodily fluids may provide insight into which downstream DNA methods to employ, these screening techniques consume a vital portion of the available evidence, are usually qualitative, and rely on visual interpretation. In contrast, qPCR yields information regarding the amount and proportion of amplifiable genetic material. In this study, dilution series of either semen or male saliva were prepared in either buffer or female blood. The samples were subjected to both lateral flow immunochromatographic test strips and qPCR analysis. Analytical figures of merit—including sensitivity, minimum distinguishable signal (MDS) and limit of detection (LOD)—were calculated and compared between methods. By applying the theory of the propagation of random errors, LODs were determined to be 0.05 μL of saliva for the RSID? Saliva cards, 0.03 μL of saliva for Quantifiler® Duo, and 0.001 μL of semen for Quantifiler® Duo. In conclusion, quantitative PCR was deemed a viable and effective screening method for subsequent DNA profiling due to its stability in different matrices, sensitivity, and low limits of detection. 相似文献

This paper offers hypotheses on the role that state social welfare measures can play in reflecting nationalism and in aggravating interethnic tensions. Social welfare is often overlooked in theoretical literature on nationalism, because of the widespread assumption that the welfare state promotes social cohesion. However, social welfare systems may face contradictions between the goal of promoting universal access to all citizens on the one hand, and social pressures to recognize particular groups in distinct ways on the other. Examples from the post-Soviet context (particularly Russia) are offered to illustrate the ways in which social welfare issues may be perceived as having ethnic connotations. 相似文献

Despite growing focus on registration and notification systems as central elements of national sex offender management practice, there has been remarkably little systematic analysis of the content of these registries and the diversity of individuals contained within them. Specifically, little research attention has been paid to examining the heterogeneity of the population of registered sex offenders — a circumstance that may obscure important distinctions within the population and, in turn, may undermine the ostensible purpose of SORN to prevent sexual victimization. Addressing this significant gap in our current knowledge, this article sets forth a national profile of the registered sex offender (RSO) population, drawn from an analysis of data on 445,127 RSOs obtained from the public registries of 49 states, Washington, DC, Puerto Rico and Guam. In contrast with the homogenized perception about registered sex offenders that permeates much public discourse, the analysis illuminates the wide diversity of registrants across a range of demographic, offense-related, registry status, and risk-oriented variables. Policy and practice implications concerning risk, prevention, and the public safety utility of sex offender registries are discussed. 相似文献

Sexual and gender-based violence in many conflict and post-conflict contexts are creating vulnerabilities to HIV. The paper is based on research conducted in Burundi in 2007–2008.The country experienced long-term civil war from the early 1990s until recently and has been the locus of post-conflict disarmament, demobilisation and reintegration programmes, providing a coherent and focused study. The research finds that the relationship between conflict and HIV/AIDS is a function of pre-existing gender relations that also regulate sexual life and determine critical female vulnerabilities. When put under stress by armed conflict, these vulnerabilities become amplified, creating conditions for the increased spread of HIV. Analysis of how gender relations and vulnerabilities change according to the specific social and economic circumstances generated by military mobilisation, organisation and deployment, in relation to civilian displacement and insecurity, in a range of distinct circumstances, provides a framework for understanding HIV vulnerabilities during and after the conflict. 相似文献

The Level of Service/Case Management Inventory (LS/CMI) and the Youth version (YLS/CMI) generate an assessment of risk/need across eight domains that are considered to be relevant for girls and boys and for women and men. Aggregated across five data sets, the predictive validity of each of the eight domains was gender-neutral. The composite total score (LS/CMI total risk/need) was strongly associated with the recidivism of males (mean r = .39, mean AUC = .746) and very strongly associated with the recidivism of females (mean r = .53, mean AUC = .827). The enhanced validity of LS total risk/need with females was traced to the exceptional validity of Substance Abuse with females. The intra-data set conclusions survived the introduction of two very large samples composed of female offenders exclusively. Finally, the mean incremental contributions of gender and the gender-by-risk level interactions in the prediction of criminal recidivism were minimal compared to the relatively strong validity of the LS/CMI risk level. Although the variance explained by gender was minimal and although high-risk cases were high-risk cases regardless of gender, the recidivism rates of lower risk females were lower than the recidivism rates of lower risk males, suggesting possible implications for test interpretation and policy. 相似文献

Few studies have been reported on the performance evaluation of automated fingerprint identification systems (AFIS) for fingermark-to-fingerprint comparisons. This paper aims to illustrate to fingerprint examiners the relevance of evaluating the AFIS performance under specific conditions by carrying out five types of performance tests. The conditions addressed are the number of minutiae assigned to a fingermark, manual and automatic assignment of the minutiae, the finger region from which the fingermark originates, the degree of distortion in the fingermark, and the difference in orientation between fingermarks and fingerprints. In these tests, the magnitude of the influence for each condition was quantified. The comparisons were performed using a research AFIS technology with simulated fingermarks. Simulated fingermarks provide a practical way to create fingermarks for specific conditions in large quantities. The results showed that each condition influences the performance significantly, emphasizing the relevance of developing, and applying performance tests for specific conditions. 相似文献

Statistical research on fingerprint identification and the testing of automated fingerprint identification system (AFIS) performances require large numbers of forensic fingermarks. These fingermarks are rarely available. This study presents a semi-automatic method to create simulated fingermarks in large quantities that model minutiae features or images of forensic fingermarks. This method takes into account several aspects contributing to the variability of forensic fingermarks such as the number of minutiae, the finger region, and the elastic deformation of the skin. To investigate the applicability of the simulated fingermarks, fingermarks have been simulated with 5-12 minutiae originating from different finger regions for six fingers. An AFIS matching algorithm was used to obtain similarity scores for comparisons between the minutiae configurations of fingerprints and the minutiae configurations of simulated and forensic fingermarks. The results showed similar scores for both types of fingermarks suggesting that the simulated fingermarks are good substitutes for forensic fingermarks. 相似文献
