Purpose

This study investigated genetic and environmental commonalities and differences between aggressive and non-aggressive antisocial behavior (ASB) in male and female child and adolescent twins, based on a newly developed self-report questionnaire with good reliability and external validity -- the Self-Report Delinquency Interview (SR-DI).

Methods

Subjects were 780 pairs of twins assessed through laboratory interviews at three time points in a longitudinal study, during which the twins were: (1) ages 9-10 years; (2) age 11-13 years, and (3) age 16-18 years.

Results

Sex differences were repeatedly observed for mean levels of ASB. In addition, diverse change patterns of genetic and environmental emerged, as a function of sex and form of ASB, during the development from childhood to adolescence. Although there was some overlap in etiologies of aggressive and non-aggressive ASB, predominantly in shared environmental factors, their genetic overlap was moderate and the non-shared environmental overlap was low.

Conclusions

Taken together, these results reinforced the importance of differentiating forms of ASB and further investigating sex differences in future research. These results should be considered in future comparisons between youth self-report and parental or teacher report of child and adolescent behavior, and may help elucidate commonalities and differences among informants.  相似文献

Freedom from personal attack and security of one's personal possessions are goals to which almost everyone subscribes ¾ from the derelicts clutching their bottles of cheap wine to millionaires worried about intrusions into their mansions. Reducing the risk of crime against our homes, our property and ourselves is a goal about which much consensus exists (Levine, et al., 1980: 22). Since formal means of crime control through the Criminal Justice Agencies only have been found to be ineffective, women must turn to community‐oriented policing as a welcome alternative for self‐protection. This article discusses the strategies women employ to cope with the rising incidence of crime.  相似文献

This study examined whether social support tied to relocation efforts and neighborhood social climate may mediate the effects of stressful life events on mental health outcomes following Hurricane Katrina. Participants were 108 adult persons made homeless by Hurricane Katrina and evacuated to Columbia, South Carolina. Civic leaders developed an intervention model that emphasized (a) a one-stop point of entry, (b) living in hotels and apartments rather than shelters, and (c) matching hotels with volunteer “hosts” to assist in relocation efforts. Results revealed that perceived neighborhood factors and satisfaction with host relationship were related to several mental health outcomes. Neighborhood social climate partially mediated several mental health outcomes. Implications of this intervention model and the utility of social ecological perspectives on homelessness interventions are discussed.  相似文献

This article provides evidence from a randomised control trial conducted among potato farmers in Ecuador about the impact of mobile phone text messages on farmer knowledge about and adoption of integrated pest management (IPM) practices. Using psychological constructs, we examine competing explanations for non-standard decision-making leading to low adoption of beneficial agricultural technologies. Farmers who received text messages have significantly higher knowledge and are more likely to adopt most IPM practices than those in the control group. Findings provide evidence that text messages lead to behavioural changes by reducing inattention and sub-optimal heuristics in the face of complex decisions.  相似文献

The Cuban situation reveals how long-lasting late-adolescent formed views, grounded in lived experiences, often prove to be, and how they may maintain meaning even after people emigrate. Those experiences may be differently interpreted depending on social class as well as age. Building on the work of Mannheim, a historically grounded generational frame of analysis helps explain why Cubans initially divided deeply over the revolution, with many of those who opposed it uprooting. It also helps explain why the first émigrés who fled the revolution continued to oppose the social transformation of their homeland, even as they assimilated in their adopted country. They continued being committed to ideas formed in their pre-immigration past. The historically grounded generational frame of analysis also helps explain why the Cuba-born who experienced the Special Period viewed life differently, whether they remained in Cuba or emigrated.  相似文献

The term professional is used in a variety of ways as people discuss issues of professionalism in the public service. There are a1so some particular concerns regarding potential conflicts between ideas of democratic control over people who have expert knowledge and skills. These various ideas of professionalism are examined, and a series of more precise defintione are offered. Time-stratified systems theory is used to clarify the concepts and to indicate how control can be exercised over various types of public employees depending upon the concept of professional being used.  相似文献

This study addresses the dynamics of the issue space in multiparty systems by examining to what extent, and under what conditions, parties respond to the issue ownership of other parties on the green issue. To understand why some issues become part and parcel of the political agenda in multiparty systems, it is crucial not only to examine the strategies of issue entrepreneurs, but also the responses of other parties. It is argued that the extent to which other parties respond to, rather than ignore, the issue mobilisation of green parties depends on two factors: how much of an electoral threat the green party poses to a specific party; and the extent to which the political and economic context makes the green issue a potential vote winner. To analyse the evolution of the green issue, a time‐series cross‐section analysis is conducted using data from the Comparative Manifestos Project for 19 West European countries from 1980–2010. The findings have important implications for understanding issue evolution in multiparty systems and how and why the dynamics of party competition on the green issue vary across time and space.  相似文献
