A dissecting intramural haematoma of the coronary artery is an infrequent cause of sudden and unexpected death. Most cases are women and in a significant number of these women, the haematoma occurred at term to 80 days postpartum. Because the intimal rupture and communication with the lumen were not found in most of the cases, the site of rupture has been considered to be a vasa vasorum. The authors report on a case of one woman who was at a later postpartum period (106 days). The microscopic finding of the dissected coronary artery revealed two intimal tears in a section. The case showed that the dissecting intramural haematoma of the coronary artery is caused not only by the rupture of the vasa vasorum but also by the rupture of the intima. 相似文献

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

1. The indications such as the place of finding, the identification of clothes or other personal items, represent only the first step towards the identification of a corpse. 2. An identification based on medical data, other than dental, is often possible, more often than it is believed. 3. The forensic pathologist plays a double role in the case of such an identification: a) in the phase of the inquiry, he must contact the investigators and the families to explain his wishes and the different possibilities of identification. b) he must use the gathered information in the appropriate way. 4. It would be desirable to compose some statistical tables of the various medical elements useful for the identification (mutilations, surgical operations, etc...). We present six cases of identification in our practice. 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

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

Considerable research has documented that global perceptions of proceduralv fairness are associated with reductions in relative
deprivation (RD). Less research has examined the specific process elements that lead individuals to perceive procedural fairness.
In view of this, several researchers have suggested that providing advance notice concerning a negative decision increases
perceived justice and thereby lowers levels of RD. Unfortunately, the evidence for this causal relationship is currently limited
and is based upon a small number of correlation and role-playing studies. Thus, the present paper reports on two experimental
studies that investigate the causal relationship between advance notice and RD. Findings in Study 1 showed that advance notice
impacted the cognitive aspects of RD but not the affective or behavioral aspects. However, some methodological limitations
were identified. These were corrected and a second experiment was conducted. This time advance notice lowered both the cognitive
and affective aspects of RD but still did not impact the behavioral measure. Results are discussed in terms of Tyler's (1987)
group value model. 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
