Forensic laboratories do not have the infrastructure to process or store contaminated DNA samples that have been recovered from a crime scene contaminated with chemical or biological warfare agents. Previous research has shown that DNA profiles can be recovered from blood exposed to several chemical warfare agents after the agent has been removed. The fate of four toxic agents, sulfur mustard, sodium 2-fluoroacetate, sarin, and diazinon, in a lysis buffer used in Promega DNA IQ extraction protocol was studied to determine if extraction would render the samples safe. Two independent analytical methods were used per agent, selected from GC-MS, 1H NMR, 19F NMR, (31)P NMR, or LC-ES MS. The methods were validated before use. Determinations were carried out in a semi-quantitative way, by direct comparison to standards. Agent levels in the elution buffer were found to be below the detectable limits for mustard, sarin, sodium 2-fluoroacetate or low (<0.02 mg/mL) for diazinon. Therefore, once extracted these DNA samples could be safely processed in a forensic laboratory. 相似文献

By questionnaire, 631 police investigators reported on their interrogation beliefs and practices-the first such survey ever conducted. Overall, participants estimated that they were 77% accurate at truth and lie detection, that 81% of suspects waive Miranda rights, that the mean length of interrogation is 1.6 hours, and that they elicit self-incriminating statements from 68% of suspects, 4.78% from innocents. Overall, 81% felt that interrogations should be recorded. As for self-reported usage of various interrogation tactics, the most common were to physically isolate suspects, identify contradictions in suspects' accounts, establish rapport, confront suspects with evidence of their guilt, and appeal to self-interests. Results were discussed for their consistency with prior research, policy implications, and methodological shortcomings. 相似文献

Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome
studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing
child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management,
self control, stimulus control, communication and child management skills training exercises, and financial management components.
Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated
by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her
responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental
control and follow-up data collection) of this case example are discussed in light of these results. 相似文献

Reviewing the literature on police-induced confessions, we identified suspect characteristics and interrogation tactics that influence confessions and their effects on juries. We concluded with a call for the mandatory electronic recording of interrogations and a consideration of other possible reforms. The preceding commentaries make important substantive points that can lead us forward—on the effects of videotaping of interrogations on case dispositions; on the study of non-custodial methods, such as the controversial Mr. Big technique; and on an analysis of why confessions, once withdrawn, elicit such intractable responses compared to statements given by child and adult victims. Toward these ends, we hope that this issue provides a platform for future research aimed at improving the diagnostic value of confession evidence. 相似文献

The characteristic that discriminates gasoline from other ignitable liquids is that it contains high‐octane blending components. This study elaborates on the idea that the presence of gasoline in fire debris samples should be based on the detection of known high‐octane blending components. The potential of the high‐octane blending component alkylate as a characteristic feature for gasoline detection and identification in fire debris samples is explored. We have devised characteristic features for the detection of alkylate and verified the presence of alkylate in a large collection of gasoline samples from petrol stations in the Netherlands. Alkylate was detected in the vast majority of the samples. It is demonstrated that alkylate can be detected in fire debris samples that contain traces of gasoline by means of routine GC‐MS methods. Detection of alkylate, alongside other gasoline blend components, results in a more solid foundation for gasoline detection and identification in fire debris samples. 相似文献

The Global Information Society (GIS) has in recent years been high on the political agenda of Western countries. These countries have been concerned with the development of Information Infrastructures in order to achieve the Information Society. In the West there has been a broad consensus about the framework in which the development of the GIS needs to take place. On both national and international levels a framework has to be established which supports competition, encourages private investment, supports flexible regulatory framework and allows for open access to networks. Recently this dominant scenario has been transposed as the appropriate scenario for the development of Information Infrastructures in the developing world. This article sets out to give an overview of GIS policy in a developmental context. It elaborates on recent policy initiatives in the area. At the international level it critically analyses changes in the communications industries and in the global economy. At the national level it critically analyses the assumptions of the dominant scenario and its proposed strategy for achieveing the GIS. 相似文献

This article analyses the determinants of individuals’ choice for self‐employment and entrepreneurial success in Cote d'Ivoire. Entrepreneurial activity is found to be undertaken by individuals who succeed in increasing their entrepreneurial abilities and reducing the risk of starting a business through a learning process that takes place through ageing, professional experience, and apprenticeship or, alternatively, formal education. The learning process takes place both before and after entry into the industry, as firms grow into a larger size. However, financial constraints continue to play a major restraining role for entrepreneurship and firm growth. 相似文献

Although people tend to mobilize around local problems and restrict their political involvement at other times, the political communication literature generally has focused on national politics and elections. This is particularly surprising in investigations of political involvement since it is at the community level that people should feel more efficacious. Also, both mass and interpersonal communication should be more significant locally given their importance in strengthening community ties. The study reported here focuses on these relationships in a community context, with a survey of six inner-city neighborhoods and six suburbs classified on status using location and census data. Results point to a much more positive role for the media in community politics. Those most likely to rely on neighborhood newspapers as sources are less disillusioned with government, suggesting that the most "grassroots" of print media are more efficacious in their impact than the other channels. Also, readership of a daily newspaper is particularly strong as a predictor of both community political involvement and faith in community civic involvement. Results of the macro analysis suggest that urban sprawl may have consequences for how media affect political involvement. In the data here, distance from the center city and stratification are closely tied--the further out the community, the higher its status. Results by neighborhood structure indicate media specialization as well as a greater dependence on media versus interpersonal influence in the political arena. Thus, we see that political involvement and attitudes are more strongly related to reading the daily newspaper in the more distant suburbs than in the center city. 相似文献

Victor Tadros’ The Ends of Harm is the most recent systematic attempt to defend the good old utilitarian justification of punishment. The attempt fails for a variety of reasons, which are here explored. First, the attempt presupposes an implausible account of human’s psychology. Second, the attempt confuses an attack on retributivism with an attack on certain criminal justice systems. Finally, Tadros admits that his justification of punishment is best seen as a mere step along the road to full-blown abolitionism – and so he unwittingly admits the extraordinarily thin sense in which he could be said to be really attempting to justify punishment. 相似文献
