Gang membership is believed to impede success in the legitimate economic market while simultaneously supporting success in the illegal market. We extend the study of the economic effects of gang membership by using a within‐ and between‐individual analytic design, decomposing gang membership into multiple statuses (i.e., entering a gang, continuously in a gang, leaving a gang, and inactive gang membership), examining legal and illegal earnings simultaneously, and accounting for factors endogenous to gang membership that may contribute to economic achievement. By using panel data from 1,213 individuals who participated in the Pathways to Desistance Study to conduct a multilevel path analysis, we find that active gang membership status is unrelated to legal earnings. Alternatively, entering a gang is associated with increased illegal earnings, attributable to changes in delinquent peers and drug use, whereas leaving a gang has a direct relationship with decreased illegal earnings. Our results indicate that the positive economic effect of gang membership (i.e., illegal earnings and total earnings) is short‐lived and that, on balance, the sum of the gang membership experience does not “pay” in terms of overall earnings.  相似文献

The understanding of positive development across adolescence rests on having a valid and equivalent measure of this construct across the breadth of this period of life. Does the Positive Youth Development (PYD) construct based on the Five Cs model have satisfactory psychometric properties for such longitudinal measurement invariance? Using longitudinal data derived from the 4-H Study of PYD, we assessed 920 youth (61.6% female) from a racially and ethically diverse sample (67.3% European American) who participated in three waves (Grades 8–10) of data collection. Building on prior findings that the Five Cs (i.e., Competence, Confidence, Connection, Character, and Caring) model of PYD was a robust measure that could be assessed comparably during early adolescence, we tested a hierarchy of second-order confirmatory factor analysis models to assess the extent to which PYD can be measured equivalently across middle adolescence. Evidence was found for strict measurement invariance across three measurement occasions, including equivalence of first-order and second-order factor loadings, equality of intercepts of observed variables, and equality of item uniqueness and disturbances of the first-order factors. These results suggest that PYD can be measured in the same way across measurement occasions, a prerequisite for the study of development. Implications for research and application of being able to measure PYD equivalently across adolescence are discussed.  相似文献

We sought to determine whether intimate partner violence (IPV) risk factors differed depending upon the presence of children in the home, and to estimate the annual prevalence of IPV first in the general population and then in homes with and without children. We analyzed data from a cross-sectional random sample of 6,836 women in southeastern Pennsylvania interviewed by telephone in 2004. The magnitude of association between IPV and risk factors varied between homes with and without children for women’s alcohol problems (with children, odds ratio (OR) 7.7; 95% confidence interval (CI) 2.9, 20.9; without children, OR 2.4; 95% CI 0.9, 6.0), and mental health problems (with children, OR 4.0; 95% CI 1.8, 8.9; without children, OR 3.0; 95% CI 1.6, 5.7). Poverty was significantly associated with IPV only in homes without children (OR 3.6; 95% CI 1.9, 7.2). Annual IPV prevalence was 1.2% overall, 1.4% in homes with children, and 1.1% in homes without children. One in 63 children lived in a home with IPV. Differences in IPV risk factors in homes with and without children suggest distinct underlying IPV mechanisms or consequences in these contexts.  相似文献

Over the past decade, the term ‘empowerment’ has been generously employed and woefully ill-defined. In particular, women's empowerment has been embraced by such a vast number of development actors that it appears to be a unifying mission within development. Despite the boom in women's empowerment initiatives, there remains little critical analysis of the use of empowerment in general, and the perceived success or failures of specific empowerment initiatives. Using the disarmament, demobilization and reintegration process in Sierra Leone as a case study, this paper examines how reintegration was described as a source of empowerment for women. Drawing from interviews and analysis of related policy discourses, it is argued that, rather than representing a radical shift in development approaches towards more inclusive and representative policies, empowerment projects are shaped by neoliberal ideas such as individualism, responsibility and economic order and carry implicit, gendered and disciplining messages about appropriate social behaviour.  相似文献

Purposes

To determine if perceived risk of criminal victimization, and past criminal victimization experiences, increases the likelihood of a person owning a gun for self-protection, and to determine if defects in past research concerning the way gun ownership was measured had obscured such effects.

Methods

We analyzed data on over 2,500 U.S. adults, using different ways of measuring gun ownership, and also analyzed future plans (among persons who did not own a gun at the time of the survey) to acquire a gun for self-protection. The latter procedure avoids the causal order problem attributable to the possibility that acquiring a gun might affect victimization risks and perceived risks, as well as the reverse.

Results

The estimated effect of perceived risk and prior victimization changed from being nonsignificant when household gun ownership was the dependent variable (as in most prior research) to being increasingly strong, and statistically significant, when gun ownership of the individual respondent for defensive reasons was measured. Further, once the causal order issue was side-stepped, risk and victimization showed even stronger, significant positive effects on planning to get a gun.

Conclusions

Crime affects gun ownership, in addition to any effects that gun ownership may have on crime.  相似文献
