The purpose of this study is to examine the longitudinal course of intimate partner violence (IPV) among female caregivers of children receiving child welfare services. Data are derived from the National Survey of Child and Adolescent Well-Being, a national probability study of children investigated for child abuse and neglect in the United States. Caregivers (n = 861) are interviewed about demographic characteristics, mental health, substance use, and physical violence by a partner at the close of the investigation and at an 18-month follow-up. Polychotomous logistic regression examines the associations of severe and minor IPV controlling for caregiver and environmental characteristics. The results suggest that factors related to initial risk for IPV do not affect the continuation of IPV and that patterns of IPV differ for racial and ethnic groups.  相似文献

The analysis of genetic variation in the nucleotide sequences of mitochondrial DNA has been used as a tool in the study of history of different human populations, as Amerindians, Afro-descendents populations and furthermore admixed populations. In this study, the mitochondrial DNA was analyzed in 158 unrelated individuals in an admixed population of the Amazonian Region: Santarém-PA-Brazil. The polymorphisms were detected using both levels, analysis of restriction enzyme and direct sequencing. We observed a total of 49 different haplotypes were found determined by 46 variable nucleotides. The more frequent haplotypes (Hap03) was shared by five samples and 43 sequences were unique. The genetic diversity was estimated to 0.989+/-0.0067 and the probability of two random individuals showed identical mitochondrial DNA (mtDNA) haplotypes were 2.8%.  相似文献

The current study found that African American residents of Oxford House (OH) used Narcotics Anonymous (NA) at high rates, and that both OH and NA strongly contributed to abstinent social networks. Having siblings and other family members in one's network predicted substance use among network members, whereas spouses, parents, and children did not have an effect on the rate of substance use. These findings suggest that OH and NA may be effective sources of abstinent social support for African Americans recovering from substance abuse. However, family members are well represented in the support networks of African Americans in OH.  相似文献

Courtship violence using couple data: characteristics and perceptions   总被引:1,自引:0,他引:1  
This study examined courtship violence using couple data. Participants were 50 heterosexual dating couples with at least one member of the couple being a university student. Using the Conflict Tactics Scales 2 (CTS2), both members of a couple reported on received and inflicted physical and psychological violence. The prevalence of physical aggression depended on how violence was defined. On the CTS2, 60% of couples were considered physically violent when within-couple agreement was not considered; this dropped to as low as 28% when agreement had to be present. Women were more likely than men to report inflicting psychological aggression and to report aggressing against their partner with a playful intent. Taken together, these findings demonstrate the need to continue to examine courtship violence, especially by utilizing responses from both members of a couple.  相似文献

In 2000, a regional rule governing maximum individual cancer risk from stationary facilities in Southern California was dramatically altered, reducing allowable risk levels by 75%. This article uses a case study approach to explore the role of a community‐based participatory research (CBPR) partnership, the Southern California Environmental Justice Collaborative, in producing research and helping spearhead policy advocacy leading to this policy change. It also highlights the role of the collaborative in helping to change the framing of the issue from individual to cumulative risk assessment, so that the regulatory agencies began to reflect this broader thinking in their policymaking. The collaborative's structure and methodology, regional focus, relationships with key decision makers, and its reputation as an important source of both credible science and “people power” were seen as contributing to its effectiveness. The role of contextual factors including a recovering and more regulation‐friendly economy also is highlighted, as are key barriers faced. Implications for other community–academic partnerships working to address regional and statewide public policy are discussed.  相似文献

Eleven Italian forensic laboratories participated in a population study based on the AB Profiler Plus loci with proficiency testing. The validated database, including 1340 individuals, is available on-line. Tests for Hardy-Weinberg equilibrium, gametic unbalance, and heterogeneity of gene frequency were generally not significant. Gene frequencies at each locus were consistent with those of two previously published Italian studies, but different from a third. Individuals of each subsample were paired, and the total number of alleles shared across the nine loci was determined in each pair. The analysis was replicated over the total sample. In addition, two samples of mother-child pairs (N=315) and full-sib pairs (N=91) were subjected to allele sharing analysis. The resulting distributions were sufficiently distinct from the sample of unrelated pairs as to be of practical usefulness.  相似文献

Naturalistic observations of learning handicapped and nonhandicapped high school girls were conducted to explore differences in the types and effectiveness of interaction strategies used during troubled peer contacts. Findings indicated that learning handicapped girls engaged in more conflict than nonhandicapped females and that this conflict generally involved dominance/submission themes and was managed in ways which increased the probability of future conflict. Conflict involving nonhandicapped girls mostly focused on selfishness or low tolerance for peer's habits and was handled in ways which lowered the likelihood of future disagreements. Implications of these findings with regard to the social standing of the learning handicapped girls in the school setting is discussed.This research was supported by Grant No. HD23097 from the National Institute of Child Health and Human Development.Received her Ed. D. from Columbia University. Current interest is social competence and family relations of learning handicapped populations.  相似文献
