Behaviors of influence and response during a conflict negotiation task were examined in eight physically child abusing, substance abusing families in which the father was the primary abuser and eight demographically matched nonabusing families. Abusing fathers displayed more coercive patterns of influencing behavior and more negative patterns of response to other family members, including both mothers and children. Fewer differences were observed between mothers in the abusing and nonabusing families or in the children's behavior; however, mothers in the abusing families criticized their husbands more and abused children exhibited less agreement and more criticism toward their fathers. In support of Patterson's theory, abusing families exhibited relatively more reciprocated sequences of criticism and relatively fewer reciprocated sequences of agreement as compared to nonabusing families. Findings are discussed in terms of their implications for understanding interaction in child abusing families.  相似文献

Conclusion Thus, there is a compelling policy argument as well as a suggestive constitutional argument that the practice of selling parental rights in general, and in particular the practice of commercial surrogacy, should not be permitted. These arguments favor the approach adopted in New York State as opposed to any more latitudinarian approach that would permit commercial surrogacy. Clearly, if the payment of money in exchange for parental rights should be prohibited, then we have a strong basis on which to reject the intentionalist theory, along with any other theory tht would link the parentage of a child with the payment of money. This conclusion is in no way undermined by the various arguments recited in part V above that favor the intentionalist theory since, as we have seen, these arguments are flawed.The author wishes to thank Gareth Matthews, Alan F. McMichael and John A. Robertson for their extremely valuable comments on earlier drafts of this article and to thank Sharon Rogers for her exceptional and unstinting editorial assistance.  相似文献

A detailed understanding of blood droplet impact dynamics and stain formation is an essential prerequisite to the interpretation of both individual bloodstains and spatter patterns. The current literature on theoretical models for the spreading and splashing of liquid drops on surfaces relevant to the forensic context of bloodstain formation has been reviewed. These models have been evaluated for a paper substrate using experimental data obtained as function of droplet size, impact velocity and angle. It is shown that for perpendicular impact there are fairly simple mathematical models for the spreading diameter and the number of scallops or spines formed around the stain though these have quite limited ranges of validity in their basic form. In particular, predictions for the diameter are best for small droplets impacting at high velocity and the number of spines saturates for higher impact velocities. In the case of spreading, a modification to the energy conservation model is found to provide excellent agreement with experimental stain diameters across a wide range of impact velocities. For non-perpendicular impact, the width of stains is found to depend principally on the normal component of impact velocity and may be predicted by an appropriate modification to the expression for the perpendicular case. Limitations in the calculation of impact angle from the stain aspect ratio are identified and a theoretical basis for the prediction of spines around an elliptical stain is proposed. Some key issues for future research are identified which include a systematic, quantitative study of the effect of surface properties on bloodstain formation.  相似文献

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

The fallibility of forensic science consultation is an ongoing and major justice concern. Prospective peer‐reviewed forensic consultation has over 10 years of application in American criminal and civil courts, adapting from the traditional oversight of teaching hospitals, rules of evidence and discovery, conventions of testimony of expert witnesses, and attorneys' overall trial strategy. In systematizing heightened oversight, this process ensures greater accountability in forensic science consultation. The integration of peer reviewers' complementary expertise and experience enhances the sophistication and overall quality of assessment. Forensic examination frequently involves the interface of different specialties. Multidisciplinary peer review augments expert proficiency with that of professional peers having different vantage points from relevant scientific disciplines. This approach ensures greater sophistication of a case inquiry, built‐in accountability, and streamlined processes when multiple experts are necessitated. Here, the authors present examples of several cases and the primary and secondary benefits of this collaborative, rigorous, cross‐disciplinary exercise.  相似文献
