Previous research has consistently shown that there is a strong association between psychological and physical aggression
in intimate relationships. Theories as to why this association exists include that they have a single underlying etiology
with differing thresholds, or they have separate etiologies and there is a two-step process by which psychological aggression
moves to physical. The current study suggests that these two theories are not necessarily competing theories. The genetic
and environmental covariance between psychological and physical intimate partner aggression were examined in 134 monozygotic
(MZ) and 41 dizygotic (DZ) twin pairs. Results showed that psychological and physical aggression have largely the same genetic
etiology, and any differences between the two are a function of differing nonshared environmental influences. 相似文献

The Role of Dissociation in the Cycle of Violence 总被引:1,自引:0,他引:1
The primary aim of this study was to examine the role of dissociation in the relationship between child maltreatment and intimate partner violence among 148 inner city women. It was proposed that dissociation would be a mediator in the relationship between child maltreatment and intimate partner perpetration. Overall, the hypothesis was supported. Findings revealed that women with a history of child maltreatment who experienced high levels of dissociation were more likely to be perpetrators of intimate partner violence than those with low levels of dissociation. 相似文献

The hypothesis that reversed blood flow in transiently occluded vertebral arteries may be responsible for some cases of massive traumatic subarachnoid haemorrhage has been investigated in vitro. Simple laboratory tests were performed on 25 vertebro-basilar arterial systems, and succeeded in producing either longitudinal tears in normally structured vertebral arteries, or tears at the origin of the posterior inferior cerebellar arteries. The results indicated that under such conditions, with systolic blood pressure in the physiological range, reversed blood flow had different characteristics and stressed the arterial wall to the point where it yielded. 相似文献

In forensic DNA analysis, the samples recovered from the crime scene are often highly degraded leading to poor PCR amplification of the larger sized STR loci. To avoid this problem, we have developed STR markers with redesigned primer sequences called "Miniplexes" to produce smaller amplicons. To assess the effectiveness of these kits, we have tested these primer sets with enzymatically degraded DNA and compared the amplifications to a commercial kit. We also conducted sensitivity and peak balance studies of three Miniplex sets. Lastly, we report a case study on two human skeletal remain samples collected from different environmental conditions. In both types of degraded DNA, the Miniplex primer sets were capable of producing more complete profiles when compared to the larger sized amplicons from the commercial kit. Correct genotypes were obtained at template concentrations as low as 31 pg/25 microL. Overall, our data confirm that our redesigned primers can increase the probability of obtaining a usable profile in situations where standard kits fail. 相似文献

The correlates of alcohol use by adolescents are compared in three cultures with different prevalences of alcohol use: France, with high prevalence; Israel, with low prevalence; and the United States, in the middle. In all three countries, significant others, parents and peers, are more powerful predictors of alcohol use than are the adolescent's personal attributes, such as attitudes, behaviors, and demographic characteristics. Cross-cultural differences appear in the relative importance of parents and peers and in the structure of influence of parents and peers as role models. Parents are more important role models in Israel than in the other two cultures, while peers are more important in the United States than in France or in Israel.This research was partially supported by Research Grants DA01902, DA00064, and Research Scientist Grant K05-DA00081 from the National Institute on Drug Abuse, and by the Center for SocioCultural Research on Drug Use, Columbia University.Received Ph.D. from Stanford University.

Using Daniel Elazar's metaphor of federalism as a matrix, asexpanded by Robert Agranoff, this article explores how stateand national political and administrative actors continue toredefine environmental federalism. The willingness of statesto sue the U.S. Environmental Protection Agency (EPA) over concernsthat the agency is not protecting the environment illustratesthe political and legal spotlight under which the matrix evolves.Outside the public purview, EPA and state environmental programadministrators attempted to shore up programs rocked by reducedbudgets and shifting priorities, while also adjusting to a newsystem of federal-state partnerships, the National EnvironmentalPerformance Partnership System. 相似文献

With the adoption of statutes, policies and administrative guidance since the late 1980s, statutory child welfare agencies around the world have been implementing practice approaches to resolving and addressing child abuse and neglect concerns that involve extended family systems in decision making and planning. One such approach is the family group conference (FGC), enshrined in New Zealand law. This article provides a historical context and describes numerous provisions of the family group conference that protect participants and the proceedings. It then describes applications of FGC‐like approaches in the United States where practice models and policies—not laws—guide the implementation of such approaches. 相似文献
