Current research suggests that a husband's substance abuse is correlated with severity of physical abuse and the woman's decision to leave a violent situation. Often, only the battered woman's report of abuse is available. This study compares women's reports of their partners' substance use/abuse with their partners' report using a brief measure of polydrug and alcohol abuse, the Substance Abuse Subtle Screening Inventory (SASSI) and the Conflict Tactics Scale (CTS). Data were analyzed for 25 recovery couples and 25 nonrecovery couples. The correlations for all 50 couples between the male's reported use and the female's report of her partner's use on the SASSI and the CTS were significant on all but one of the CTS scales. They ranged on SASSI from .73 to .33 and from .31 to .06 on the CTS. This suggests that the SASSI and possibly the CTS could be used as valuable tools for assessing women's reports of their partner's substance use/abuse. 相似文献

The purpose of this investigation was to identify inmate personal and demographic data that may be used to further define
or profile persons with a greater likelihood of being at risk for serving a jail sentence. This study was explorative. The
survey administration was similar in format to that conducted by the U.S. Department of Justice. Chaplains were used as survey
proctors. Pilot studies were conducted to determine the suitability of survey content. Surveys consisted of 172 items. Subjects
included four hundred inmates: males comprised 88.75 percent of the sample, Caucasians 58.25 percent, Blacks 37 percent, Hispanics
3.25 percent and other 1.5 percent of the sample. Respondents ranged in age from 15 to 64 years with an average age of 30.3
years. Less than two percent of the contacted inmates refused participation in the survey. Results are presented for demographic
data, select legal/criminal data, select drug and alcohol use data, employment data, health, parent/family data, education
data, social data, and “other”. 相似文献

A growing body of evidence shows that minorities are disproportionately the targets of police brutality, but important theoretical questions about the causes of that inequity remain unanswered. One promising line of research involves structural‐level analyses of the incidence of police brutality complaints; however, existing studies do not incorporate variables from alternative theoretical explanations. Drawing on the community accountability hypothesis and the threat hypothesis, we tested the predictions of two prominent structural‐level explanations of police brutality in a study of civil rights criminal complaints. The study included cities of 150,000+ population (n = 114). The findings reveal that two community accountability variables—ratio percent Hispanic citizens to percent Hispanic police officers and the presence of citizen review—were related positively to police brutality complaints, partially supporting that perspective. Two threat hypothesis measures of threatening people—percent black and percent Hispanic (in the Southwest)—were related positively to complaints, as predicted. The relative degree of support for the two hypotheses is assessed. 相似文献

A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques. 总被引:2,自引:0,他引:2

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

Threatening and otherwise inappropriate letters to members of the United States Congress 总被引:2,自引:0,他引:2
P E Dietz D B Matthews D A Martell T M Stewart D R Hrouda J Warren 《Journal of forensic sciences》1991,36(5):1445-1468
The authors examine the characteristics of threatening and otherwise inappropriate communications sent to members of the U.S. Congress by a sample of 86 subjects, 20 of whom threatened assassination. We quote excerpts from these letters and provide quantitative data on such variables as the volume, duration, form, and appearance of such communications; the enclosures; the subjects' perceived relationships to the recipients; the thematic content of the communications; and the messages and threats communicated. Comparisons between 43 subjects who pursued encounters with members of Congress and 43 who did not revealed 17 factors associated with such pursuit. In this population, threateners were significantly less likely to pursue an encounter than inappropriate letter writers who did not threaten, regardless of the type of threat or the harm threatened. Inappropriate letters to members of Congress are compared with those directed to Hollywood celebrities. Mentally disordered persons writing to public figures often mention and sometimes threaten public figures other than those to whom the letters are addressed, which raises important issues regarding notification of endangered third parties and the sharing of information among protective agencies. 相似文献
