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 psychological assessment battery is an integral part of the selection process used to select patrol officer applicants.
Unlike all other procedures used in the selection process, the psychological assessment has not been adequately validated.
The purpose of this study was an attempt to provide validation data for a psychological assessment battery. The battery consisted
of the Nelson-Denny, Shipley-Hartford, MMPI, and the Motivational Analysis Test (MAT). Performance measures included various
measures of training academy performance and field training performance. A stepwise regression and MANOVA/Discriminant Analysis
indicated that the psychological tests did predict performance, although an exact predictive equation could not be developed
due to the high intercorrelations between predictor variables.
This research was sponsored in part by a grant from the School of Applied Arts and Technology, Southwest Texas State University. 相似文献

Historically, small businesses have been the innovation engine of the United States, with significantly more than half of the new technologies and products coming from small enterprises. In 1992, there were more than 21 million small businesses with fewer than 500 employees each in the United States, including 4.5 million small corporations, 1.6 million partnerships, and 15.1 million sole proprietorships. Although most small businesses have considerably fewer than 100 employees, they employ more than half the private U.S. work force, contribute more than half of all sales in the country, and are responsible for over half of the private sector's products. From 1976 to 1990, small firms also generated 65% of the net new jobs. From 1988 to 1990, all of the net new jobs in the U.S. economy were created by small firms. Indeed, small business is really big business in the United States. 相似文献

This study uses a structured vignette procedure to assess competency to make treatment decisions in two groups of adolescents, one at risk for institutional placement and the other a matched community sample. Scores on Factual Understanding (the ability to recall facts), Inferential Understanding (the ability to make inferences about those facts), and Reasoning (the ability to weigh risks and benefits of various treatment options and to make choices based on that reasoning) were compared. Results showed that while at-risk adolescents and their community, counterparts did not differ in their factual and inferential understanding abilities, the at-risk adolescents did significantly less well than the community adolescents in reasoning. This difference could not be fully explained by differences in verbal IQ. Girls, no matter what their risk status, scored higher than boys on the Reasoning scale. Implications for legal policies concerning adolescents are discussed. 相似文献

Analyzes the results of forensic medical examinations of the corpses after hanging. The findings were as follows: two strangulation grooves are seen on the corpse's neck after hanging, that are similar to the grooves seen after strangulation with a loop and subsequent hanging of a corpse; the presence of bruises on the neck, along with the strangulation grooves, is indicative of a strangulation made by the hands, whereas half-moon shaped bruises may be self-inflicted during hanging. 相似文献
