A growing literature suggests that communication strategies can promote or inhibit intimate partner violence (IPV). Research on communication is still needed on a group ripe for early IPV intervention: high school-aged adolescents. This article revisits our previous analyses of young female reproductive clinic patients (Messinger, Davidson, & Rickert, 2011) by examining how the adolescent and young adult respondents differ. To explore replicability of the adolescent results across populations, they are compared to 487 adolescent female students sampled from four urban high schools. Across samples, all communication strategies were used more frequently within violent relationships. Multivariate analysis identified escalating strategies used and received as being positively associated with physical violence used and received in all three samples. Regarding verbal reasoning and temporary conflict avoidance, substantial differences appeared between the young adult and adolescent clinic samples, and results from the adolescent clinic sample were largely replicated with the adolescent school sample, suggesting that young adult samples in this literature are not adequate proxies for adolescents.  相似文献

Statutes criminalizing behavior that risks transmission of HIV/AIDS exemplify use of the criminal law against individuals who are victims of infectious disease. These statutes, despite their frequency, are misguided in terms of the goals of the criminal law and the public health aim of reducing overall burdens of disease, for at least three important reasons. First, they identify individual offenders for punishment, a paradigm that is misplaced in the most typical contexts of transmission of infectious disease and even for HIV/AIDS, despite claims of AIDS exceptionalism. Second, although there are examples of individuals who transmit infectious disease in a manner that fits the criminal law paradigm of identification of individual offenders for deterrence or retribution, these examples are limited and can be accommodated by existing criminal laws not devoted specifically to infectious disease. Third, and most importantly, the current criminal laws regarding HIV/AIDS, like many other criminal laws applied to infectious disease transmission, have been misguided in focusing on punishment of the diseased individual as a wrongful transmitter. Instead of individual offenders, activities that enhance the scale of disease transmission—behaviors that might be characterized as ‘transmission facilitation’—are a more appropriate target for the criminal law. Examples are trafficking in human beings (including sex trafficking, organ trafficking, and labor trafficking), suppression of information about the emergence of infection in circumstances in which there is a legally established obligation to disclose, and intentional or reckless activities to discourage disease treatment or prevention. Difficulties remain with justifications for criminalizing even these behaviors, however, most importantly the need for trust in reducing overall burdens of disease, problems in identifying individual responsible offenders, and potential misalignment between static criminal law and the changing nature of infectious disease.  相似文献

Analyzing the Influence of Micro-Level Factors on CCTV Camera Effect   总被引:1,自引:0,他引:1  

Objectives

Despite the popularity of closed circuit television (CCTV), evidence of its crime prevention capabilities is inconclusive. Research has largely reported CCTV effect as “mixed” without explaining this variance. The current study contributes to the literature by testing the influence of several micro-level factors on changes in crime levels within CCTV areas of Newark, NJ.

Methods

Viewsheds, denoting the line-of-sight of CCTV cameras, were units of analysis (N = 117). Location quotients, controlling for viewshed size and control-area crime incidence, measured changes in the levels of six crime categories, from the pre-installation period to the post-installation period. Ordinary least squares regression models tested the influence of specific micro-level factors—environmental features, camera line-of-sight, enforcement activity, and camera design—on each crime category.

Results

First, the influence of environmental features differed across crime categories, with specific environs being related to the reduction of certain crimes and the increase of others. Second, CCTV-generated enforcement was related to the reduction of overall crime, violent crime and theft-from-auto. Third, obstructions to CCTV line-of-sight caused by immovable objects were related to increased levels of auto theft and decreased levels of violent crime, theft from auto and robbery.

Conclusions

The findings suggest that CCTV operations should be designed in a manner that heightens their deterrent effect. Specifically, police should account for the presence of crime generators/attractors and ground-level obstructions when selecting camera sites, and design the operational strategy in a manner that generates maximum levels of enforcement.  相似文献

This paper addresses the relationship between law and coercive force. It defends, against Frederick Schauer's contrary claims, the following propositions: (a) The force of law consists in three things, not one: the imposition of duties, the use of coercion, and the exercise of social power. These are different and distinct. (b) Even if coercion is not part of the concept of law, coercion is connected to law many important ways, and these are amply recognized in contemporary analytic jurisprudence. (c) We cannot determine how important coercion is to the efficacy of law until we know what counts as coercive force. The question of what counts as coercion is not a matter for generalization or stipulation. It requires an explanation of the concept of coercion.  相似文献

Gatekeeping has been used as a theory and a measure to describe and assess family dynamics within the context of separation and divorce. In this article, we explore adaptive and maladaptive gatekeeping behaviors and attitudes that can affect the other parent's relationship with the child. Implications are presented for connecting adaptive and maladaptive gatekeeping responses to child outcomes of safety, well‐being, and positive parent–child relationships following separation and divorce. We build on the recent attention to gatekeeping as a potential framework within the child custody context.  相似文献

Research has documented a negative relationship between religion and risky sexual behavior. Few studies, however, have examined the processes whereby religion exerts this effect. The present study develops and tests a model of various mechanisms whereby parental religiosity reduces the likelihood of adolescents’ participation in risky sexual behavior (early sexual debut, multiple sexual partners, and inconsistent condom use). Structural equation modeling, using longitudinal data from a sample of 612 African American adolescents (55% female), provided support for the model. The results indicated that parental religiosity influenced adolescent risky sexual behavior through its impact on authoritative parenting, adolescent religiosity, and adolescent affiliation with less sexually permissive peers. Some mediating mechanisms differed by the gender of the respondent, suggesting a “double-standard” for daughters but not for sons. Findings also indicated the importance of messages about sexual behavior that are transmitted to adolescents by their peers. Theoretical and policy implications of the findings are discussed.  相似文献

Approximately 81.7 million cats are in 37.5 million U.S. households. Shed fur can be criminal evidence because of transfer to victims, suspects, and/or their belongings. To improve cat hairs as forensic evidence, the mtDNA control region from single hairs, with and without root tags, was sequenced. A dataset of a 402-bp control region segment from 174 random-bred cats representing four U.S. geographic areas was generated to determine the informativeness of the mtDNA region. Thirty-two mtDNA mitotypes were observed ranging in frequencies from 0.6-27%. Four common types occurred in all populations. Low heteroplasmy, 1.7%, was determined. Unique mitotypes were found in 18 individuals, 10.3% of the population studied. The calculated discrimination power implied that 8.3 of 10 randomly selected individuals can be excluded by this region. The genetic characteristics of the region and the generated dataset support the use of this cat mtDNA region in forensic applications.  相似文献
