Unfortunately, the nature‐versus‐nurture debate continues in criminology. Over the past 5 years, the number of heritability studies in criminology has surged. These studies invariably report sizeable heritability estimates (~50 percent) and minimal effects of the so‐called shared environment for crime and related outcomes. Reports of such high heritabilities for such complex social behaviors are surprising, and findings indicating negligible shared environmental influences (usually interpreted to include parenting and community factors) seem implausible given extensive criminological research demonstrating their significance. Importantly, however, the models on which these estimates are based have fatal flaws for complex social behaviors such as crime. Moreover, the goal of heritability studies—partitioning the effects of nature and nurture—is misguided given the bidirectional, interactional relationship among genes, cells, organisms, and environments. This study provides a critique of heritability study methods and assumptions to illuminate the dubious foundations of heritability estimates and questions the rationale and utility of partitioning genetic and environmental effects. After critiquing the major models, we call for an end to heritability studies. We then present what we perceive to be a more useful biosocial research agenda that is consonant with and informed by recent advances in our understanding of gene function and developmental plasticity. 相似文献

随着科技的发展及其不断深入到人们生活的方方面面,对刑事证据制度的影响越来越大。科技影响了刑事证据制度的变迁;扩大了刑事证据的范围,使越来越多的非自然物进入证据之列;对于收集、固定和保全刑事证据,既提供了新的手段,也提出了新的挑战;同时对于刑事证据的采信规则也产生了影响。从科技的角度研究刑事证据,可以为我国建立完善刑事证据规则奠定理论基础。 相似文献

ABSTRACTThe paper deals with the issue of overpricing of public procurement in low-performing EU countries. It examines a uniquely large sample of public procurement in 11 Central and Eastern European countries. Hierarchical regression is used to analyze the factors that influence public contract. Our results indicate that institutional factors have a greater impact on overpricing than individual decisions by the contracting authority. Our analysis for low-performing EU countries provides interesting results and also draws attention to behavior that is not typical of the better established and more advanced EU countries. Our results are particularly important for public policy in each country, as they show the direction of regulatory action in the field of public procurement. The results introduce a debate on the appropriateness of “one size fits all” regulations within the EU. 相似文献

The forensic scenario, on which the round robin study was based, simulated a suspected intentional manipulation of a real estate rental agreement consisting of a total of three pages. The aims of this study were to (i) establish the amount and reliability of information extractable from a single type of evidence and to (ii) provide suggestions on the most suitable combination of compatible techniques for a multi-modal imaging approach to forgery detection. To address these aims, seventeen laboratories from sixteen countries were invited to answer the following tasks questions: (i) which printing technique was used? (ii) were the three pages printed with the same printer? (iii) were the three pages made from the same paper? (iv) were the three pages originally stapled? (v) were the headings and signatures written with the same ink? and (vi) were headings and signatures of the same age on all pages? The methods used were classified into the following categories: Optical spectroscopy, including multispectral imaging, smartphone mapping, UV-luminescence and LIBS; Infrared spectroscopy, including Raman and FTIR (micro-)spectroscopy; X-ray spectroscopy, including SEM-EDX, PIXE and XPS; Mass spectrometry, including ICPMS, SIMS, MALDI and LDIMS; Electrostatic imaging, as well as non-imaging methods, such as non-multimodal visual inspection, (micro-)spectroscopy, physical testing and thin layer chromatography. The performance of the techniques was evaluated as the proportion of discriminated sample pairs to all possible sample pairs. For the undiscriminated sample pairs, a distinction was made between undecidability and false positive claims. It was found that none of the methods used were able to solve all tasks completely and/or correctly and that certain methods were a priori judged unsuitable by the laboratories for some tasks. Correct results were generally achieved for the discrimination of printer toners, whereas incorrect results in the discrimination of inks. For the discrimination of paper, solid state analytical methods proved to be superior to mass spectrometric methods. None of the participating laboratories deemed addressing ink age feasible. It was concluded that correct forensic statements can only be achieved by the complementary application of different methods and that the classical approach of round robin studies to send standardised subsamples to the participants is not feasible for a true multimodal approach if the techniques are not available at one location. 相似文献

Longitudinal research has seriously challenged assumptions that juvenile sex offenders (JSO) are characterized by high level of dangerousness, mental health problems, and crime specialization in sex offenses. The current study examines the longitudinal pattern of offending among a sample of JSO and a sample of juvenile nonsex offenders. The research design includes longitudinal data over a nine-year period allowing the examination of offending patterns and the crime mix from age 12 to age 23. The findings highlight that, while JSO are prone to persist offending in adulthood, there is limited continuity of sex offending. Further, the findings stress the importance of taking into account nonsexual juvenile delinquency, more specifically, youth violence, to make a better assessment of early adult offending outcomes of JSO. 相似文献

强奸案件的证据采信问题在司法实践中颇受争议,出现这种现象的主要原因在于其直接证据的稀缺。针对强奸案件的证据收集和运用中所存在一系列的疑难情形,司法机关不必追求证据之间无任何矛盾,而要从全案证据出发,采取"自由心证"与"相互印证"相结合的证明方法,并运用对质制度,做到完整证据链条支持下的内心确认即可。 相似文献

随着社会竞争的加剧,生活节奏的加快,人们承受的压力也越来越大,近些年来公务员作为一个特殊群体其压力问题也受到学术界的关注。学者从压力源、影响压力大小的因素,如何应对压力等几个方面对此进行了定性和定量研究,取得了一定的成果,但由于公务员压力问题研究刚刚起步,还有许多方面有待完善。 相似文献
