Recent interest in the construct of motivation to change among male perpetrators of intimate partner violence (IPV) has led to development of two self-report measures of this construct: the University of Rhode Island Change Assessment for Domestic Violence (URICA-DV; Levesque et al. 2000) and the Safe at Home Inventory (SAH; Begun et al. 2003). We examined the internal structure of these instruments using confirmatory and exploratory factor analyses in a sample of 199 male IPV perpetrators waiting to begin court-mandated batterer intervention programs. Results indicated that the scales had adequate internal consistency. However, using confirmatory factor analyses, the hypothesized structural models of each instrument fit the data poorly. Subsequent models suggested by a series of exploratory factor analyses failed to improve model fit substantially for both scales. For the URICA-DV, a 3-factor model including items from the Precontemplation, Contemplation, and Action subscales fit the data adequately. No acceptable model fit could be found for the SAH. Intercorrelations among similar subscales across the two inventories suggested only a modest degree of intercorrelation (r’s = 0.16–0.52), and a factor structure more dependent on scale of origin than item latent content, suggesting that the scales assess different facets of the readiness to change construct. These results suggest that before the stages of change construct can be fully applied to the IPV area, more research and evaluation are needed on how to accurately assess abuser readiness to change.  相似文献

The distribution of plasminogen phenotypes in the population of Veneto was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 1325), the three common phenotypes PLG1, PLG2, PLG2-1 and two further phenotypes PLG1-V and PLG2-V were, observed and the following frequencies calculated: PLG1 = 0.84038; PLG2 = 0.15811; PLGV = 0.00151. These gene frequencies are compared to those found in other populations. Analysis of 41 mother-child pairs was in agreement with an autosomal codominant inheritance.  相似文献

A synoptic study of six cases of self-inflicted sharp force injuries is presented, where young, mostly female people had simulated assaults to gain sympathy or other personal advantage. The morphological distinctives of simulated assault wounds from such of real assault are worked out and the common situative and motivative background is cleared up.  相似文献

Historically, disease scares reveal contradictions in the social order. We postulate that courts focus on depoliticizing social tensions revealed by AIDS, legitimating the routines of dominant parties in the AIDS sociolegal network. At the same time, courts deviate from their normal practices try upholding the claims of subordinate parties in this network, particularly people living with AIDS (PWAs) and their allies. Our analysis of 36 AlDS-related court rulings, published during the formative years of AIDS litigation in the United States, supports the notion that courts operate as "double-edged" institutions. To explain the duality of judicial decision making, we concentrate on the powers of social and cultural factors rather than on the doctrinal judgments of the courts. We trace how relational attributes, evident in contestants' characteristics (e.g., plaintiff/defendant, status differentials) and the nature of claims (i.e., restrictive/expansive), combine to account for wins for dominant parties and how other combinations of these attributes define wins for subordinate parties. We also show how judges combine specific interpretational attributes in the text of their rulings (e.g., use of divisive AIDS metaphors, deference to medical authority) to justify wins. We consolidate these findings to discuss how PWAs and their allies might use the courts to their advantage and point out the ways in which the changing epidemiology of AIDS in the United States limits the use of courts.  相似文献

In a random group of medical examiner cases, muscle tissue, as well as blood and vitreous humor, was analyzed for ethyl alcohol, and the results were compared. When the blood concentration was greater than 0.10 g/dL, the muscle to blood ratio was 1.00 or less (average 0.94), and when the blood concentration was less than 0.10 g/dL, this ratio was greater than 1.00 (average 1.48). The author proposes that this ratio is dependent upon the time course of absorption and distribution, as has been observed for vitreous humor, but with a more rapid equilibration. Muscle tissue was also analyzed in another group of cases found to be positive for one or more drugs in blood. The concentrations of the drugs in muscle varied from none detected to 6.5 times those in blood and seemed to be dependent on the time course between ingestion and death, as well as on the nature of the drug. For most common basic drugs, the ratios were often near unity. Muscle is proposed as a useful alternative specimen to postmortem blood.  相似文献
