“冤案”与司法活动——从卡夫卡《审判》看

冤案研究应从日常司法的关于是否存在冤案的对立认识入手,而非公认冤案。而发生对立认识时,基于角色担当和功能作用的理由,应主要支持司法活动。社会公众及个人,在冤案对立认识及日常活动中,也有自己的行动责任。卡夫卡《审判》是展开这些探讨的极佳素材。     

The Physical Effects of Contact and Close‐Distance Gunfire on Sweatshirt Fleece

Powder stippling caused by the impact of propellant particles during close‐distance gunfire has been previously described on skin and solid objects only. Additionally, radial tearing has been described as clear evidence of a contact‐distance shot, requiring no further testing. Patterns of discrete perforating holes (referred to here as “stippling perforations”) and other physical damage on sweatshirt fleece fabrics were prepared. Using the firearm and ammunition in this study, stippling perforations were observed to a maximum muzzle‐to‐target distance of 35 cm (10 inches). In addition, radial tearing and disintegration were present (and often more extensive) at greater than contact distance. The presence of stippling perforations could augment muzzle‐to‐target distance estimates generated using the Griess test, or allow distance estimates when the Griess test is not feasible. Unlike what has been previously reported, testing on the original evidence (or similar substitute) is warranted when physical damage is used to estimate shooting distance.     

LIFESTYLE,RATIONAL CHOICE,AND ADOLESCENT FEAR: A TEST OF A RISK‐ASSESSMENT FRAMEWORK*

Criminological research on fear of crime primarily has been based on, and supportive of, an opportunity framework. The current research tests an expanded risk‐assessment model of fear, which is rooted in an opportunity framework, by incorporating a measure of delinquent lifestyle, which is a known risk factor for victimization, using a sample of youth aged 10–16 years. The findings from longitudinal structural equation models do not support the applicability of a risk‐assessment model of fear in adolescence. Namely, although increased involvement in a delinquent lifestyle is associated strongly with an increase in victimization over time, no such association exists with the perceived risk of victimization. Most importantly, as adolescents become more involved in a delinquent lifestyle and are victimized at a higher rate than nondelinquent youth, their fear of victimization actually decreases at a significantly higher rate than more prosocial youth.

Intensity and Breadth of Participation in Organized Activities During the Adolescent Years: Multiple Associations with Youth Outcomes

The goal of this study was to examine initial levels and rates of change in the intensity and breadth of participation in organized activities during the adolescent years, and how these participation practices were related to youth outcomes in later adolescence. The main objectives were (a) to examine growth curves of intensity and breadth of participation from Grades 7 through 11 and their interrelations, and (b) to test the associations between these dimensions of participation and academic orientation, risky behaviors, internalizing problems, and civic development in Grade 11. A homogenous sample of 299 youth (mean age = 13.37, SD = .41; 62% girls) were surveyed annually using questionnaires and phone interviews. The main results revealed that (a) even though both intensity and breadth of participation decreased over time, intensity of participation showed steeper declines by later grades, and (b) initial levels of participation were better predictors of later outcomes than rates of change over time. Regardless of the levels of change taking place over time, results revealed that youth with high initial levels of participation (both intensity and breadth) were more committed to school and developed more positive values towards society by Grade 11 than those who participated less. This might suggest that a high level of participation during early-to-mid-adolescence is particularly important when it comes to later outcomes.     

中国青年志愿服务发展的演进脉络

上世纪50年代的青年志愿垦荒活动是中国青年志愿服务的雏形;上世纪60年代兴起的学雷锋活动是计划经济时代青年志愿服务存在的最基本方式,青年志愿服务活动在彰显雷锋精神的情况下缓慢发展;上世纪90年代初期,中国青年志愿旗号的打出,青年志愿服务的广泛开展,标志着现代青年志愿服务的真正兴起;北京奥运会为中国志愿服务的发展提供了一个难得的历史机遇,中国青年志愿服务借助这一盛事获得进一步的发展。     

Lifestyle and Routine Activity Theories Revisited: The Importance of “Risk” to the Study of Victimization

Lifestyle and routine activity theories both view victimization through the lens of the convergence of a motivated offender, an attractive target/victim, and the absence of capable guardianship. These theories differ, however, in how they view the behaviors that put people at “risk” for victimization. Where lifestyle theory conceives of risk in probabilistic terms (e.g., certain behaviors elevate one’s odds of being victimized), routine activity theory simply describes the victimization event itself (e.g., if the three key elements converge, victimization happens, yet if one of the elements is missing, victimization is avoided). We argue that this difference is meaningful and that its disappearance over time has been consequential to the study of victimization. Our purpose here is to outline the implications of this difference in the conception of risk for victimization theory, research, and policy. Our broader goal is to reignite a theoretical debate that we feel is long overdue.
