正当性、合理性和现实性——世贸组织法中发展中国家的特殊和差别待遇

在GATT/WTO中争取特殊和差别待遇是发展中国家成员要求建立公平的国际贸易秩序的表现。这种公平的实现是从应有权利到法定权利再到现实权利的权利实践过程。本文分析了影响该权利实践过程和结果的一系列变量,指出发展中国家只有增强自身的参与能力,加强整体的团结,才有可能走向成功的权利实践。WTO应进一步强化规则和纪律,切实保证发达国家成员履行对发展中国家成员的义条,后者才能从特殊和差别待遇中真正受益。     

绵羊卵母细胞的差异蛋白质组学研究

为了研究绵羊卵母细胞成熟过程中蛋白质的表达模式,以期在蛋白质水平探索绵羊卵母细胞成熟的分子机制,将采用双向凝胶电泳技术获得的2-DE图谱经PDQuest8.0分析并找出差异蛋白斑点后,对差异蛋白斑点进行高效液相色谱串联离子阱质谱分析。结果显示,GV期和MⅡ期卵母细胞2-DE图谱之间存在13个表达差异明显的蛋白斑点;4个蛋白斑点的质谱检测结果较为理想,对应3种不同的蛋白质,分别为截短的VP2、苹果酸脱氢酶、谷胱甘肽转移酶M3;其中截短的VP2、苹果酸脱氢酶在卵母细胞成熟过程中表达量下调,谷胱甘肽转移酶M3在卵母细胞中大量表达并且表达量上调。结果表明,绵羊卵母细胞成熟过程中,细胞的mRNA合成和表达水平以及糖代谢水平可能降低,细胞的抗氧化和解毒能力可能提高。     

Racial composition,sentencing reforms,and rates of incarceration, 1970–1980

Association with delinquent peer groups is one of the most salient predictors of delinquent behavior. Despite the widespread documentation of these effects, little is known about whether the delinquent peer effect is conditioned by individual‐level characteristics. Using data from a multi‐wave survey of Mexican‐American adolescents, this study explored the interactive effect of susceptibility to peer influence and differential association with delinquent peers on delinquent outcomes. Results suggested that the delinquent peer effect on self‐reported delinquency is amplified when an adolescent is highly susceptible to peer influence. Analyses also indicated that this moderating effect varies according to offense seriousness. Specifically, the conditioning effect is most important when considering acts of serious delinquency.     

Familial Correlates of Overt and Relational Aggression between Young Adolescent Siblings

Multi-group confirmatory factor analysis and multi-group structural equation modeling were used to test correlates of overt and relational aggression between young adolescent siblings across four groups (i.e., male/male, male/female, female/male, and female/female sibling pairs), using 433 predominately European American families. Similar patterns of associations were found across groups when distinguished by gender composition. Family environment emerged as an important factor in explaining internalizing problems as well as overt/relational aggression for both younger and older siblings. While perceived maternal psychological control was significantly positively related to overt/relational aggression and internalizing problems for younger siblings, it was significantly positively associated with only relational aggression for older siblings. Findings also provided partial support for the positive linkages between young adolescents’ aggression and their own and siblings’ internalizing problems above and beyond the aforementioned family and maternal variables. Results of the current study extend the understanding of adolescent aggression to a new relational context, or among siblings, and highlight the role of family factors in promoting or buffering the impact of aggression on internalizing behaviors.

Delinquent networks in Sweden

This study covers all persons under the age of 20 who were suspected of having committed a crime in the Swedish city of Borlänge (approx. 50,000 inhabitants) during the years of 1975–1977. The juveniles (575 in all) were followed up during a total of 10 years. A sociometric method based on police data was developed for studying co-offending patterns. The method was validated through a smaller number of interviews with the juveniles. This study shows that a large majority of the most delinquency active juveniles was associated with a large network of delinquent relations. The stronger the connection to this network, the more substantial, serious, and long-lasting were the delinquency and other asociality. This network also seemed to be very important with regard to the reproduction of juvenile delinquency in the municipality. At the end of the follow-up period juvenile delinquency in Borlänge had basically the same character as at the beginning, even though the juveniles included in the network were, to a large extent, new. The young offenders who were central figures in the new network had successively learned their roles from the network's old members.This paper is based on results published initially in a report entitledDelinquent Networks (Sarnecki, 1986).     

The Effects of Adolescent Activities on Delinquency: A Differential Involvement Approach

T. Hirschi’s (1969, Causes of Delinquency. University of California Press, Berkeley, CA) control theory proposes that involvement, as an element of the social bond, should reduce delinquency. But, research studies have found that the effect of involvement is rather weak. This study reformulates Hirschi’s involvement hypothesis by posing involvement as a social setting variable and a differential factor. Certain activities provide a social setting favorable to the development of the social bond and the reduction in delinquent association. The reformulated hypothesis is examined based on a sample of Grade 7–12 students in a Western Canadian city. The results reveal that school- and family-related activities strengthen the social bond and reduce delinquent association and delinquency. In contrast, other conventional activities such as spending time with friends and dating have the opposite effects. In addition, the indirect effect of differential involvement on delinquency through the social bond and delinquent association is stronger than its direct effect. Thus, the undesirable effects of the less-positive activities on delinquency may be buffered or reduced by strengthening the social bond and reducing delinquent association.Siu Kwong Wong is an Associate Professor of Sociology at Brandon University.

Reconsidering strain theory: Operationalization,rival theories,and adult criminality

Recently a revisionist view of strain theory's empirical adequacy has emerged which holds that the theory's explanatory power depends on how it is operationalized. With an adult community sample, we empirically assess three separate measures of strain to explain self-reported crime: the gap between aspirations and expectations, blocked opportunities, and relative deprivation. The findings reveal that the aspirations-expectations measure is not related to criminal involvement, while perceived blocked opportunities and feelings of relative deprivation significantly affect adult offending. These relationships, however, fail to persist after measures from competing theories (i.e., low self-control, differential association, and social bond) are introduced as controls in the regression equations. Thus, measures from rival theories offer a more fruitful approach to explaining self-reported adult offending.A version of this paper was presented at the 1993 American Society of Criminology meetings, Phoenix, Arizona.

Friends,Cognition, and Delinquency: Proactive and Reactive Criminal Thinking as Mediators of the Peer Influence and Peer Selection Effects among Male Delinquents

The purpose of this study was to determine whether criminal thinking underpins peer influence and selection. It was predicted that proactive criminal thinking would mediate the peer influence effect (peers?→?offending) and reactive criminal thinking would mediate the peer selection effect (offending?→?peers). Participants were 1,170 male delinquent youth from the Pathways to Desistance study. The Moral Disengagement scale (proactive criminal thinking) and Peer Delinquent Behavior scale (peer delinquency) were cross-lagged to predict criminal offending, and the Weinberger Impulse Control scale (reactive criminal thinking) and criminal offending were cross-lagged to predict peer delinquency. Consistent with predictions, proactive but not reactive criminal thinking successfully mediated the peer?→?offending relationship and reactive but not proactive criminal thinking successfully mediated the offending?→?peer relationship. Whereas delinquent peer associations appear to promote proactive criminal thinking and peer influence, early criminal offending appears to promote reactive criminal thinking and peer selection.     

Updating,subtyping, and perceptions of the police: Implications of police contact for youths’ perceptions of procedural justice

Individuals enter police encounters with expectations about how these interactions will unfold. These expectations are often rooted in racialized personal, vicarious, and collective experiences with the police. Bayesian updating posits that the way youth perceive treatment by the police during stops and arrests combines with prior expectations and perceptions to shape current views of the law, whereas subtyping suggests this process differs by race. This study examines intra- and interracial variability in these processes using longitudinal survey data from 3,085 Black and White youth. Regardless of race, youth who indicate they were treated with disrespect during police encounters had lower perceptions of procedural justice than did those with no contact, whereas contact perceived as respectful had no significant effects. For White but not Black youth, police encounters rated as “neutral” are associated with more negative views of the police. Other forms of legal socialization are also racialized, including messages conveyed in the media and by parents. Limited evidence exists that prior views of the police moderate the effect of police encounters on procedural justice or that these conditioning effects vary by race. Findings support updating, but race differences do not neatly align with findings expected with updating or subtyping theory.
