Despite broad consensus that most juvenile crimes are committed with peers, many questions regarding developmental and individual differences in criminal style (i.e., co-offending vs. solo offending) remain unanswered. Using prospective 3-year longitudinal data from 937 14- to 17-year-old serious male offenders, the present study investigates whether youths tend to offend alone, in groups, or a combination of the two; whether these patterns change with age; and whether youths who engage in a particular style share distinguishing characteristics. Trajectory analyses examining criminal styles over age revealed that, while most youth evinced both types of offending, two distinct groups emerged: an increasingly solo offender trajectory (83%); and a mixed style offender trajectory (17%). Alternate analyses revealed (5.5%) exclusively solo offenders (i.e., only committed solo offenses over 3 years). There were no significant differences between groups in individuals?? reported number of friends, quality of friendships, or extraversion. However, the increasingly solo and exclusively solo offenders reported more psychosocial maturity, lower rates of anxiety, fewer psychopathic traits, less gang involvement and less self reported offending than mixed style offenders. Findings suggest that increasingly and exclusively solo offenders are not loners, as they are sometimes portrayed, and that exclusively solo offending during adolescence, while rare and previously misunderstood, may not be a risk factor in and of itself.  相似文献

Although there is a knowledge base regarding theoretical and empirical research on attitudes toward the police, this line of research has not fully examined the sources of such attitudes, and in particular the extent to which attitudes toward the police are influenced by ethnic identity. The present study examined the role of ethnic identity in African American adolescent offenders' perceptions of general police discrimination, direct police contact, procedural justice, and police legitimacy. Analyses showed that youth with a stronger sense of ethnic identity perceived more police discrimination but reported more positive beliefs about police legitimacy. The findings underscore the importance of considering processes that may make legal socialization experiences more salient for adolescents, and demonstrate the complex role that ethnic identity plays in relation to discrimination.  相似文献

The Russian attitude towards the European Neighbourhood Policy constitutes a serious obstacle to the realisation of the Union's agenda in its neighbourhood. The Russian challenge takes three main forms: 1) with Russia not a part of the EU's overall approach involving the principle of conditionality, the Union's legitimacy and international actorness in general is in danger of being undermined; 2) Russia is increasingly starting to put forward its own model of operation, thus hampering the realisation of the Union's goals in the neighbourhood; 3) Russia is engaging in business activities that are in effect undoing the ENP's energy component. There are no easy fixes to these problems. What the Union must do is believe in its own values and visions: it is only by example that it can promote its ideals outside its institutional boundaries.  相似文献

The Oprah Winfrey Show provides an interesting set of contradictions. On the one hand, it appears to challenge common-sense assumptions about relationships, specifically heterosexual relationships (for example, by consistently raising issues of sexual violence within a heterosexual context). Yet, at the same time, Oprah's presentation often works to reinforce precisely the norms she seeks to challenge. Through a close analysis of a selection of programme clips from one particular programme among many about relationships, sexuality and families, this article will consider the ways in which the Oprah Winfrey Show both problematizes and yet normalizes the boundaries of heterosexuality. Here we shall discuss both the resolute exposure and exploration of what could be termed the casualities of normative (and compulsory) heterosexuality and, paradoxically, its recuperation as a ‘rational’ ideal. In exploring the ways in which this recuperation takes place, we shall begin with a brief consideration of two of the key discourses which shape the show: the discourse of therapy and that of kinship. Our analysis of the sexual politics of the Oprah Winfrey Show in these terms will focus on the programme, ‘How to Make Love Last’ (18 January 1993). Like so many other programmes, ‘How to Make Love Last’ intends to highlight and deal with problems within heterosexual relationships as distressing but solvable (through the medium of therapeutic self-help). At another level, however, the programme also (unwittingly) reveals a different order of problems which, ironically, can only be reinforced by the mode of rescue proposed and staged.  相似文献

SUMMARY

Technological developments in recent years have provided greater scope in the selection and combination of media for presenting courses in distance education. This article explores the uses and limitations of a number of ‘old’ and ‘new’ media in distance education from the perspective of their educational and communication advantages. The main emphasis is not on technological developments, but on the potential of various media to create a greater degree of interaction between tutor and student than has previously been possible through traditional media such as print and audio-visual media.  相似文献

Although prior research finds a robust link between delinquent behavior and expectations, or an adolescent’s perceived likelihood of obtaining one’s future goals, fewer studies have evaluated aspirations, or the perceived importance of achieving one’s goals. In addition, few studies consider how individual traits such as impulsivity affect the degree to which expectations and aspirations motivate or deter delinquent behavior. We contribute to this body of research by evaluating the independent effects of expectations and aspirations, and the aspiration-expectation gap (i.e., strain) on delinquent behavior during the year following an adolescent’s first arrest using a large (N?=?1117), racially/ethnically diverse sample of male adolescents (46.55% Latino, 35.81% Black, 14.95% White, and 2.69% Other race). In addition, we considered how impulse control interacts with expectations, aspirations, and strain to motivate behavior. Our results indicated that both aspirations, expectations and strain uniquely influence criminal behavior. Importantly, aspirations interacted with impulse control, such that aspirations affected delinquency only among youth with higher impulse control. Our findings suggest that aspirations may only influence behavior if youth also have the psychosocial capabilities to consider their future aspirations when behaving in the present.  相似文献

Social ecological theories and decades of supporting research suggest that contexts exert a powerful influence on adolescent delinquency. Individual traits, such as impulse control, also pose a developmental disadvantage to adolescents through increasing risk of delinquency. However, such individual differences may also predispose some youth to struggle more in adverse environments, but also to excel in enriched environments. Despite the prominence of impulse control in both developmental and criminological literatures, researchers are only beginning to consider impulse control as an individual characteristic that may affect developmental outcomes in response to environmental input. Using a racially diverse (Latino 46?%; Black 37?%; White 15?%; other race 2?%) sample of 1,216 first-time, male, juvenile offenders from the longitudinal Crossroads Study, this study examined key interactions between baseline impulse control and the home, school, and neighborhood contexts in relation to delinquency within the following 6 months. The results indicated that even after accounting for prior delinquency, youth in more negative home, school, and neighborhood contexts engaged in the same amount of delinquency in the following 6 months regardless of their level of impulse control. However, the effects of positive home, school, and neighborhood contexts on delinquency were stronger for youth with moderate or high impulse control and minimally affected youth with low impulse control. The findings suggest two risk factors for delinquency: low impulse control as a dispositional vulnerability that operates independently of developmental context, and a second that results from a contextual vulnerability.  相似文献
