One important aspect of the economic theory of criminal court delay is to understand how the prosecutor and the defendant make their decisions, and how these respond to changes in trial delay. If both parties jointly maximise expected utility, trial delay may increase or decrease the number of trials, depending upon the decision makers' attitudes towards risk. The main policy implication is that providing the criminal courts with more resources in the form of additional judges and court capacity may lengthen the trial queue rather than shorten it. This is a counterintuitive result contrary to popular belief. 相似文献

In different theoretical traditions, negative social conditions, attachments, and interactions shape the way individuals view the law and its agents. Although most researchers acknowledge the conceptual distinction between different legal attitudes such as legal cynicism and police legitimacy, it remains unclear to what extent these attitudes stem from the same social sources. In the current study, therefore, we evaluate the social and individual factors that influence trajectories of legal cynicism and police legitimacy using a diverse community sample of youths in Zurich, Switzerland. Latent growth curve models were employed to examine patterns of change in legal cynicism and police legitimacy between 13 and 20 years of age. The findings show that legal cynicism and police legitimacy both decline into early adulthood and exhibit high rank-stability over time. Furthermore, we find that legal cynicism is closely related to individual characteristics that reflect one's inability to recognize or abide by their internal rules. By contrast, police legitimacy is shaped by socialization influences, particularly teacher bonds and police contacts. These results indicate a need to assess the measurement and interpretation of legal cynicism critically in relation to broader legitimacy beliefs and to investigate the shared and distinct sources of these different constructs. 相似文献

新中国成立以来,面对国内外安全环境的变化,中国实现了由传统安全观向总体国家安全观的演变,显著体现在安全环境研判、安全内容认知和安全维护手段三个方面。中共十八大以来,中国在安全方面频繁推出新理念、新方案和新举措,中国的安全能力不断增强,国际安全影响日益增加。在安全观方面,中国先后提出了总体国家安全观、亚洲新安全观、亚太安全观等理念,实现了安全观的变革与创新。安全环境研判方面,对国内安全的认知更加全面系统、对周边安全的认知更加统筹协调、对国际安全认知更加注重“中国作为”;安全内容认知方面,认知内容日益丰富,兼顾传统安全与非传统安全,统筹国家安全与人民安全;安全维护手段方面,不断完善国家安全体系、加强国家安全能力建设和推进国际安全合作。回顾新中国七十年国家安全观的演变,历经安全实践的锤炼,已经形成了一些基本经验,主要体现在安全环境研判需考虑内外因素并注重其联动性、坚持核心安全需求的底线和安全维护手段要以和为贵、文攻武备。展望未来,其重要启示在于中国的国家安全观要注重安全需求与安全能力之间的平衡,将安全能力建设视为至关重要的任务,不断促进安全维护手段的多样性和灵活性。 相似文献

运用项目反应理论分析不同认知特点的题目 总被引:2,自引:0,他引:2
项目反应理论和认知心理学是两个不同的研究领域 ,把它们结合起来可以得到更多的题目信息。通常人们只是利用了项目反应理论提供的项目难度、区分度等统计指标 ,本研究发现对于具有不同认知特点的题目 ,它们的项目特征曲线和差异性系数是有显著差异的。高分组和低分组在认知结构上的差异 ,也可以通过项目特征曲线反映出来 相似文献

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h. 相似文献

尿液、血液中γ-羟丁酸的气质联用法分析 总被引:3,自引:0,他引:3
目的为尿液、血液中γ-羟丁酸(gamma-hydroxybutyricacid,GHB),γ-羟丁酸内酯(gamma-butyrolactone,GBL)和1,4-丁二醇(1,4-butanediol,1,4-BD)的鉴定提供方法和依据。方法100μl尿液或血液以GHBd6为内标,经乙酸乙酯提取、BSTFA衍生化后,用GC/MS法分析。结果测尿液中内源性GHB的线性范围是20-800ng/ml,R2=0.9995,最低检出限为10ng/ml(S/N≥3);测尿液、血液中外源性GHB的线性范围为5-60μg/ml,R2分别为0.9999和0.9928。相对回收率为99%-104%。以所建方法测定了健康志愿者尿液中内源性GHB含量,并考察了健康受试者外源性GHB的代谢情况。结论所建方法准确、便捷、省时、选择性好,适用于法医毒物学鉴定。 相似文献

Determination of sex from fragmentary crania is a critical problem in forensic anthropology. Osteometric analysis of mastoid can serve forensic anthropologists better in sex identification by virtue of the noticeable dimorphic characteristics. The present study aims to develop population-specific, sex-differentiating anthropometric standards for the mastoid process of North Indian skulls. Eight parameters of the mastoid region were measured on 138 adult crania (M/F 104:34, 22-65 years) and analyzed using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.000). In stepwise analysis, asterion-mastoidale and mastoid breadth have provided an accuracy of 87%. Receiver operating characteristic curves were obtained for each variable to observe their overall performance in sex determination. Posterior end of incisura mastoidea-depression of suprameatal triangle was found to be the best variable with maximum area under curve and highest predictive accuracy (82.6%). 相似文献
