Objective
We examine the relationship between early criminal involvement and school dropout, and analyze which factors underlie this relationship, making use of administrative data from the Netherlands.Methods
We start by determining the unconditional correlation between early criminal involvement and school dropout, using a basic ordinary least squares model. As this association is likely to be driven by different factors, we proceed by including an extensive set of observable family and individual characteristics into the estimation model. We further proceed to models that account for the influence of unobservable heterogeneity by estimating school, class, sibling and twin fixed effects.Results
Criminal involvement is associated with an 11 percentage point higher probability of school dropout. The magnitude of this relationship decreases gradually when we account for larger shares of observed and unobserved heterogeneity. The coefficient in the same-gender twin fixed effects model indicates a 3 percentage point higher probability of school dropout, which is statistically significant at a 10 % level. We also find that the association between criminal involvement and school dropout is stronger if juveniles are involved in severe criminal activities.Conclusions
We conclude that the observable and unobservable factors for which we account explain around 73 % of the unconditional correlation between criminal involvement and school dropout. The remaining variation likely reflects individual-specific characteristics that are different between same-gender twins. A true treatment effect, if existing, is likely to be relatively small. At the same time, serious criminal behavior appears to causally affect school dropout.12.
This paper exploits cross country data on regulatory delay for 135 countries. The results from the regression analysis suggest that waiting time stemming from business procedures has a negative impact on economic growth, especially when we take into account possible endogeneity. 相似文献

The European Clinical Trial Directive (2001/20/EC) was implemented into the Belgian legal system by the Law of 7 May 2004 concerning experiments on the human person (LEH). Apart from implementing the European Directive, this law also broadens the scope of the Directive from interventional clinical trials to all medical experiments involving human persons. This article offers an overview of the requirements for involving minors in medical experiments that are captured in the LEH, illustrates the process of protocol review by an ethics committee, and discusses the dissimilarities between the LEH and the European Directive. 相似文献

The aim of this five-wave longitudinal study was to investigate the relationship between anxiety and adolescent identity development.
Participants were 1,313 adolescents who annually completed measures of anxiety and identity. Growth Mixture Modeling (GMM)
analyses demonstrated that the adolescent population was best typified by two latent growth trajectory classes: a low anxiety class (n = 1,199) characterized by a low initial level of anxiety that decreased over time and a high anxiety class (n = 114) characterized by a higher initial level of anxiety that increased over time. To answer our research question, we tested
a model in which the anxiety classes predicted initial levels and rates of change of three identity dimensions: commitment,
in-depth exploration, and reconsideration of commitment. Findings indicated that the high anxiety adolescents displayed a
more troublesome identity development than their low anxiety peers, since their commitments became weaker with age, and they
reconsidered them intensively.

Although the relation between family relationships and the timing of sexual debut has been the focus of many studies, research
on mediating factors is scarce. This study examines whether low levels of family cohesion result in an earlier onset of romantic
and sexual experiences, and whether the link between family cohesion and an early sexual debut is mediated by early romantic
initiation. A longitudinal sample of 314 adolescent girls and 222 boys, aged 12–17 at Wave 1, completed questionnaires at
three measurement points with three year intervals. The results showed that sexual debut followed romantic initiation for
77% of the participants. For early adolescent females (aged 12–14), high levels of family cohesion resulted in a later sexual
debut and this association was fully mediated by a delay of romantic initiation. Among boys and older girls, timing of romantic
initiation did not mediate the link between family cohesion and timing of sexual initiation. Early adolescent girls who have
negative relationships with their parents turn to romantic relationships for intimacy and support, which subsequently provide
the opportunity for an early sexual debut. Low levels of family cohesion thus primarily precipitate romantic initiation and
sexual initiation appears to be secondary to this process among girls in this age group. 相似文献

The longitudinal effects among self and identity processes, and between these processes and internalizing symptoms, are not well understood. As a result, the present study was designed to ascertain the over-time effects among identity commitment, reconsideration of commitments, and self-concept clarity, as well as to map the interplay of these self and identity processes with anxiety and depressive symptoms in early adolescence. A sample of 923 Dutch adolescents (mean age 12.4 years at Time 1; 49.3% female) participated at each of five annual assessments. Multivariate growth curve and cross-lagged panel models indicated that the association between self-concept clarity and commitment was bidirectional, that reconsideration occurs based on problems or dissatisfaction with self-concept clarity and with identity commitments, and that self-concept clarity (but not commitment or reconsideration) temporally precedes depressive and anxiety symptoms. Results are discussed in terms of the structure of the self-system and its associations with internalizing symptoms. 相似文献

ABSTRACT The current study had three aims: (1) to explore whether there is over-time change in adolescent delinquency and negativity in the parent–adolescent, sibling and marital relationships during adolescence; (2) to examine the interactions of negativity across subsystems; and (3) to examine whether levels and changes in adolescent delinquency are predicted by levels and changes in negativity in all family subsystems. Data of 497 families participating in the RADAR-young study were used. Ratings of all family members were used to measure negativity in family relationships, and adolescent self-report was used for delinquency. Multivariate latent growth curve models showed over-time increases in mother-adolescent negativity and over-time decreases in sibling negativity, as well as significant individual differences in these changes. Second, evidence for both social contagion and compensatory processes in family negativity was found. Third, initial levels of parent–adolescent negativity were related to initial levels but not over-time changes of adolescent delinquency, whereas initial levels of sibling negativity were related to over-time changes but not initial levels of adolescent delinquency. Finally, increases in parent–adolescent negativity were related to faster increases in adolescent delinquency, and decreases in sibling negativity were related to slower increases in adolescent delinquency. Implications of these results are discussed. 相似文献

Criminal groups and transnational illegal markets 总被引:4,自引:0,他引:4
In the study of organised crime, thetraditional view of criminal groups ascentrally controlled organisations has beenreplaced by the notion of criminalnetworks. However, little use has been madeof concepts and theories of social networksthat have developed in other socialsciences. This paper uses concepts fromsocial network theory to describe andtentatively explain differences in socialorganisation between criminal groups thatperform three types of transnationalillegal activities: smuggling andlarge-scale heroine trading, trafficking inwomen, and trading stolen cars. Groups thatoperate in the large-scale heroin markettend to be close-knit, cohesive andethnically homogenous. Groups active in thetrafficking of women have a chain structure, while those that operate in themarket for stolen cars are characterised bythree clusters of offenders in a chain.Both groups are less cohesive than criminalgroups in the large-scale heroin marketare. The differences in social organisationbetween the three types of illegalactivities appear to be related to thelegal and financial risks associated withthe crimes in question, and thereby to therequired level of trust betweencollaborating criminals. 相似文献
