Psychopathy among condemned capital murderers

Psychopathy is an important forensic mental health construct. Despite this importance, the research base of psychopathy among individuals convicted of capital murder is limited. Archival data were collected from a sample of 636 persons convicted of capital murder and sentenced to death in the State of California. Psychopathy was assessed using the Psychopathy Checklist – Revised (PCL-R) instrument. Data on criminal careers and other behavioral disorders were also extracted. The sample mean PCL-R total score was 23.31 (SD = 9.92) and one-third of individuals in this sample were considered clinically psychopathic with PCL-R total scores of 30 or greater. Factor analytic examination yielded support for four facets: affective, interpersonal, lifestyle, and antisocial. Criterion validity findings revealed positive correlations of psychopathy scores with Antisocial Personality Disorder (ρ = 0.72), Conduct Disorder (ρ = 0.46), sexual sadism (ρ = 0.24), Oppositional Defiant Disorder (ρ = 0.20), ADHD (ρ = 0.15), arrest charges (r = 0.56), prison sentences (r = 0.53), and age of arrest onset (r = −0.57). Individuals convicted of capital murder and sentenced to death reflect heterogeneity in psychopathy with some individuals exhibiting pronounced psychopathic features.     

Accuracy of comparison decisions by forensic firearms examiners

This black box study assessed the performance of forensic firearms examiners in the United States. It involved three different types of firearms and 173 volunteers who performed a total of 8640 comparisons of both bullets and cartridge cases. The overall false-positive error rate was estimated as 0.656% and 0.933% for bullets and cartridge cases, respectively, while the rate of false negatives was estimated as 2.87% and 1.87% for bullets and cartridge cases, respectively. The majority of errors were made by a limited number of examiners. Because chi-square tests of independence strongly suggest that error probabilities are not the same for each examiner, these are maximum-likelihood estimates based on the beta-binomial probability model and do not depend on an assumption of equal examiner-specific error rates. Corresponding 95% confidence intervals are (0.305%, 1.42%) and (0.548%, 1.57%) for false positives for bullets and cartridge cases, respectively, and (1.89%, 4.26%) and (1.16%, 2.99%) for false negatives for bullets and cartridge cases, respectively. The results of this study are consistent with prior studies, despite its comprehensive design and challenging specimens.     

遵约与国际制度的有效性:情投意合还是一厢情愿

20世纪90年代,国际关系学与国际法学开始走上了相互借鉴、学习的道路。国际关系学者和法学研究者在遵约研究方面具有共同的议程,遵约研究已经成为国际关系理论的重要方面。遵约被国际关系学界用来衡量制度的因果影响,具有一定的客观性。但是,遵约与国际制度有效性之间并不具有必然的联系,遵约是对制度因果关系的误读。此外,认识论、方法论上及分析层次、内生性问题上也对遵约研究提出了挑战。遵约研究对制度有效性的启示在于:应该慎重选择衡量结果的指标,从而准确评估制度对国家政策和行为的因果影响。     

试论基础四国在后哥本哈根气候谈判中的立场和作用

基础四国是由中国、印度、巴西和南非四个主要发展中国家组成的气候谈判集团,鉴于其成员在发展中国家和世界上的影响力,该集团在国际气候谈判中备受关注。在构建2012年后国际气候机制的谈判中,基础四国的立场表现出了很高的协调性,但也存在一定的差异。总体而言,基础四国的出现和协调行动推动了国际气候谈判在公约框架下展开,有利于后京都气候安排的达成,但也可能促使国际气候谈判集团,特别是G77加中国的分化和重新组合。基础四国气候谈判集团出现时间尚短,其最终能够在构建后京都气候机制中发挥何种作用将取决于基础四国在应对气候变化中如何对待联合国渠道与其他渠道的关系、敦促发达国家减排的决心和能力以及是否能够保持G77加中国内部的团结性等。     

Family judges in the city of Buenos Aires: a view from within

This paper summarises the main findings of a study of gender differences in the values and attitudes of family judges carried out in Buenos Aires, Argentina. The study explored how men and women judges understood their profession and its requirements, their representation of the ideal family judge, their motivation to become family judges, the way they experienced the power they wield, and their opinion on the supposed contributions women judges might bring to the family judiciary. The study's findings were analysed in terms of Gilligan's ethic of justice/ethic of care approach. Two key results emerged. Firstly, there were no clear-cut differences between men and women in terms of their adherence to an ethic of justice or of care respectively. Secondly, distinct gender differences were apparent in the way women judges approached decision-making.     

Trajectories of Peer Social Influences as Long-term Predictors of Drug Use from Early Through Late Adolescence

The present study analyzed the long-term effects of perceived friend use and perceived peer use on adolescents’ own cigarette, alcohol and marijuana use as a series of parallel growth curves that were estimated in two developmental pieces, representing middle and high school (N = 1,040). Data were drawn from a large drug abuse prevention trial, the Midwestern Prevention Project (MPP). Results showed that both perceived peer and friend cigarette use predicted own cigarette use within and across the adolescent years. For own alcohol and marijuana use, peer and friend influences were limited primarily to middle school. The findings suggest that strategies for counteracting peer and friend influences should receive early emphasis in prevention programs that are targeted to middle school. The findings also raise the question of whether cigarette use may represent a symbol of peer group identity that is unlike other drug use, and once formed, may have lasting adverse effects through the adolescent years.

The Average Treatment and Its Cost,Age, and Gender of Patients With Ischemic Heart Diseases

Ensuring efficient treatment of patients in hospital care, with precise management of resources and cost planning. Goals： Dividing the patients with ischemic heart diseases into five groups with the highest cost of treatment, and determining the link among the cost of treatment and the average length of hospital stay, age, and gender of these patients. Materials and methods： Standardized reports of 10,040 patients from three hospitals in Macedonia from 2010 to 2012 were used. The databases were processed in SPSS 17, and the ANOVA and the Chi-square test were applied. Results and discussion： There is a statistically significant difference between the groups which have different cost of treatment and the average length of their treatment （F = 183.63 and p = 0.000） and a statistically significant difference between the five most expensive groups of patients in terms of their gender （Chi-square = 370.262, df = 4, and p = 0.000）. Furthermore, there are statistically significant differences between patients with different cost of treatment in terms of their age （F = 24.25 and p = 0.000）. Conclusion： The ＂most expensive＂ patients have the longest average hospital stay.     

A comparison of three shoe sole impression lifting methods at high substrate temperatures

Footwear impressions are a common form of evidence found at crime scenes, and the accurate recovery and recording of such impressions is critical for shoe sole comparison and identification. The lifting of shoe sole impressions from hot surfaces (>30°C/86°F) and in hot environments has received little attention in the literature, particularly in relation to the recovery of class and randomly acquired characteristics (RACs) required for accurate comparisons. This study addressed this knowledge gap by comparing the performance of three common impression lifters (gelatin, adhesive, and vinyl static cling film) at recovering shoe sole impressions in dust from hot flooring substrates. Dry origin dust shoe sole impressions were made on ceramic tile, galvanized metal, and laminated wood flooring using a shoe that possessed two RACs and five class characteristics present on the sole. Substrates were left in direct full sun for five hours during a summer day prior to lifting. Performance was measured by the proportion of RACs and class characteristics visible in each lifted impression. Results demonstrated that the vinyl static cling film tested performed poorly across all substrates, particularly for metal (23.8% marks recovered), including notable shrinkage of the lifted impression. In contrast, adhesive (~96% marks recovered over all substrates), and to a lesser extent gelatin (~85%), lifts were highly successful on hot substrates. These data suggest that adhesive lifts can consistently and accurately recover shoe sole impressions from hot substrates. This study contributes critical information for crime scene examiners to improve and expand evidence recovery in hot environments.
