Body fluid traces recovered at crime scenes are among the most common and important types of forensic evidence. However, the ability to characterize a biological stain at a crime scene nondestructively has not yet been demonstrated. Here, we expand the Raman spectroscopic approach for the identification of dry traces of pure body fluids to address the problem of heterogeneous contamination, which can impair the performance of conventional methods. The concept of multidimensional Raman signatures was utilized for the identification of blood in dry traces contaminated with sand, dust, and soil. Multiple Raman spectra were acquired from the samples via automatic scanning, and the contribution of blood was evaluated through the fitting quality using spectroscopic signature components. The spatial mapping technique allowed for detection of “hot spots” dominated by blood contribution. The proposed method has great potential for blood identification in highly contaminated samples. 相似文献

This paper provides the first empirical test of the Portia Hypothesis:Females with masculine monikers are more successful in legalcareers. Utilizing South Carolina microdata, we look for correlationbetween an individual's advancement to a judgeship and his/hername's masculinity, which we construct from the joint empiricaldistribution of names and gender in the state's entire populationof registered voters. We find robust evidence that nominallymasculine females are favored over other females. Hence, ourresults support the Portia Hypothesis. 相似文献

Deoxyribonucleic acid (DNA) restriction fragment length polymorphism (RFLP) profile results were obtained from bloodstains and other body fluid stains subjected to mixture with other body fluids, environmental insults (sunlight and temperature), different substrates (cotton, nylon, blue denim, glass, aluminum, and wood), and contaminants (gasoline, bleach, sodium hydroxide, soil, motor oil, detergent, phosphate salt, glacial acetic acid, and microorganisms). Of the samples that produced profile results, all had profiles that were consistent with those of untreated control samples. 相似文献

Social scientists need clarification about the extent to which the confidential aspects of their research are protected from compulsory disclosure in legal proceedings, and the extent to which they ought to be. Investigating the nature of social science research with an emphasis on researcher-participant relationships in ethnographic practice, I conclude that a qualified privilege would confer three major benefits on social science researchers: confidence that the government will not unnecessarily interfere with research, facilitation of improved researcher-participant relationships, and increased accuracy, thoroughness, and reliability of research data. I also discuss the development of privilege and confidentiality issues in practical research contexts through an examination of two criminal cases in which social science researchers refused to divulge the confidential information obtained in the course of research. Finally, I discuss the possible formulations of a scholarly research privilege. This is especially important because courts have cast social scientists as members of the larger community of academic or scholarly researchers with respect to these issues. Potential sources of protection include state journalist protection laws, federal common law, and federal statutory law. Evaluation of these sources and the case law to which they correspond suggests that developing common law privileges in state and federal jurisprudence is the most promising means of affording the confidential aspects of social science research legal protection.

The utility of the National Incident-Based Reporting System (NIBRS) forstrategic crime analysis has yet to be explored. The NIBRS represents anadvancement over existing reporting systems and possesses considerableutility to frontline law enforcement with respect to strategic crimeanalysis. This paper discusses the utility of the NIBRS for identifyinglocal and regional trends in narcotics related offenses. As an example, weselected four localities from the 1997 Virginia NIBRS data to examine trendsin the sale/distribution and possession of narcotics. Our analysis showsthat the NIBRS provides significantly more incident-related detail than hasheretofore been available for strategic crime analysis at the regional orstate level. Moreover, the NIBRS provides neighboring communities theopportunity to compare information on emerging crime patterns and criminalenterprises which extend beyond local boundaries. Finally, enhancing localreporting compliance by highlighting the strategic utility of the data tolocal law enforcement will ultimately ensure the quality of the data set,which can then be employed by larger entities as well as criminal justiceresearchers for policy development and planning. 相似文献

The mental health needs of prisoners are significant with a high incidence of common mental health problems including anxiety and depression. Extending national initiatives such as the National Health Service Improving Access of Psychological Therapies programme to people in prison offers a valuable opportunity to address these mental health problems and improve continuity of care from prison to the community. This study adopts an observational, prospective cohort design and evaluates an IAPT for offenders service over the first three years of operation within a male Category B prison holding remand/convicted prisoners. The evaluation found large effect sizes for changes in anxiety and depression with clinical recovery being achieved in 55% of depression and 52% of anxiety cases. On average, prisoners were treated in less than five sessions employing a low-intensity cognitive-behavioural approach. The lack of established formal diagnoses and a control group limits the findings. 相似文献
