Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

冠心病猝死心肌肌动蛋白缺失的免疫组织化学定量研究

应用免疫组织化学LSAB法和图像处理系统，对德国慕尼黑大学法医学研究所1994年尸检冠心病猝死和对照组病例（各15例）的心肌肌动蛋白缺失情况进行定量研究。发现冠心病猝死病例心肌纤维内有明显的肌动蛋白缺失，是大小不一，多发、散在分布；对照组无或仅局限性小灶状缺失。将检测结果定量分析比较，其差异非常显著，说明重度冠状动脉粥样硬化患者是否冠心病猝死，其心肌肌动蛋白缺失的范围和程度有明显差异，冠心病猝死和对照组病例心肌肌动蛋白缺失的差异具有诊断意义，而形态定量分析能较客观准确地反映心肌纤维内肌动蛋白缺失量的变化。     

人心肌梗死心肌肌钙蛋白T脱失的免疫组化观察

目的 观察人梗死心肌中心肌肌钙蛋白T的脱失情况，探讨其在人心肌梗死死后诊断中的应用价值。方法 应用免疫组化LSAB法，对人心肌梗死心肌肌钙蛋白T的脱失情况观察。结果 人梗死心肌肌钙蛋白T有明显脱失，通过计算机图像分析显示，人梗死心肌肌钙蛋白T的脱失面积与正常人心肌之间存在显著性差异(P＜0.01)。结论 心肌肌钙蛋白T(CTnT)可能成为人心肌梗死的诊断指标之一。     

领导的内在结构和领导活动规律解析

领导构成有权力、责任和服务三大要素;政治领导、组织领导和思想领导是我们党执政的三种基本类型,但从广义的领导范畴来说,领导的类型并不仅仅限于这三种。作为一个完整的领导活动,领导是由三个最基本的实体构成的,即:领导者、被领导者和作用对象。领导活动的三个规律可表述为:合力集成规律、同心圆规律和镜面反射规律。     

Raising a big tent: Internal party composition and leadership selectorate expansion

The trend amongst many parties toward the inclusion of rank-and-file members in the leadership selection process has often been attributed to opposition status and electoral defeat. However, these explanations are typical events for parties and hardly seem sufficient for party elites to willingly cede their authority over the selection of party leaders. This paper proposes that the electoral regionalization of the party contributes to the decision to expand the leadership selectorate. In the event a party is defeated to an extent in which their support is reduced to its regional base, this situation necessitates the bringing in of new voices to avoid further marginalization. This paper finds that regionalization plays a significant role in the decision of parties to expand leadership selectorates and that the role of opposition status and electoral setbacks have been overstated.

Early Adolescents’ Social Standing in Peer Groups: Behavioral Correlates of Stability and Change

Sociometric nominations, social cognitive maps, and self-report questionnaires were completed in consecutive years by 327 students (56% girls) followed longitudinally from grade 7 to grade 8 to examine the stability of social standing in peer groups and correlates of changes in social standing. Social preference, perceived popularity, network centrality, and leadership were moderately stable from grade 7 to grade 8. Alcohol use and relational aggression in grade 7 predicted changes in social preference and centrality, respectively, between grade 7 and grade 8, but these effects were moderated by gender and ethnicity. Changes in social standing from grade 7 to grade 8 were unrelated to grade 8 physical aggression, relational aggression, and alcohol use after controlling for the grade 7 corollaries of these behaviors. Results are discussed in terms of their implications for understanding links between social standing and problem behaviors during adolescence.
