In the last several decades, the American family has undergone considerable change, with less than half of all adolescents residing with two married biological parents. Using the National Longitudinal Survey of Youth 1997, we construct an elaborate measure of family structure and find considerable heterogeneity in the risk of antisocial and delinquent behavior among groups of youth who reside in what are traditionally dichotomized as intact and nonintact families. In particular, we find that youth in “intact” families differ in important ways depending on whether the two biological parents are married or cohabiting and on whether they have children from a previous relationship. In addition, we find that youth who reside with a single biological parent who cohabits with a nonbiological partner exhibit an unusually high rate of antisocial behavior, especially if the custodial parent is the biological father.  相似文献

Local officials and national observers have attributed the New York City drop in violent crime during the 1990s to the aggressive enforcement of public order, but relevant research is limited and yields contrasting conclusions regarding the effects of order‐maintenance policing (OMP) on violent crime trends in New York City. The current study investigates the effects of order‐maintenance arrests on precinct‐level robbery and homicide trends in New York City with more reliable crime and arrest data, longer time series, and more extensive controls for other influences than used in prior research. We find statistically significant but small crime‐reduction effects of OMP and conclude that the impact of aggressive order enforcement on the reduction in homicide and robbery rates in New York City during the 1990s was modest at best.  相似文献

This research attempts to elaborate a routine activity model of violent victimization by incorporating an explicit rational choice perspective on potential targets’ decision making to avoid violent encounters. We propose that the costs associated with a violent attack and the probability of offender retaliation depend on whether the offender's targeting strategy is opportunistic or deliberate—a function of the relational distance between the offender and target. Specifically, we propose that victim efforts to limit exposure to an offender may motivate a violent retaliatory response when the victim and offender are intimates compared to when they are strangers. We develop hypotheses based on these ideas and test them using data from the National Crime Victimization Survey (1992–2000). The results suggest that female targets are more sensitive to an offender's targeting strategy than are males. We conclude with a discussion of how knowledge of the potential risk of violent retaliation on the part of intimate and spousal offenders can be used to create more efficacious policies to protect victims of violence.  相似文献

This article examines ticket splitting in five different mixed‐member electoral systems—Germany, New Zealand, Japan, Lithuania, and RussiA—and indicates the shortcomings inherent in any analysis of such ticket splitting that does not take into account the presence of the personal vote. We find that the personal vote plays a central part in shaping ticket splitting in all of our cases except for Germany, a heavily party‐oriented system in which we find evidence of only a weak personal vote but evidence of substantial strategic voting.  相似文献

This article examines the use of alternative sentencing provisions as mechanisms for departing from sentencing guidelines in Washington State and as structural sources of unwarranted sentencing disparity. The authors argue that these structural features of guidelines not only serve as “windows of discretion” through which disparities arise, but they also may encourage disparities by requiring consideration of substantive criteria that disadvantage certain offender groups. The analyses find that males and minority offenders are less likely to receive alternative sentences below the standard range, but that race‐ethnicity and gender have inconsistent effects on departures above the standard range. Theoretical implications of the study are discussed.  相似文献

Globalization may not be coming apart at the seams—yet—but the seams are ever more apparent. Rising fuel prices challenge a model of global transportation based on cheap energy, reinforcing the possibility of decoupling through great regionaliza‐tion of trade. Already, 50 percent of trade among ASEAN plus China and Japan is among each other. The Wall Street meltdown has spread a lack of confidence in the American financial system and the model of deregulation which stimulated rapid globalization of capital flows. Along with other developments, all this raises the question of whether the United States is prepared to operate successfully in a world it no longer dominates. An anti‐globalization leader, a former US labor secretary, a top American intellectual and a Nobel laureate address these issues.  相似文献
