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

In a free market world economy now characterized by a strong trend towards integrated economic areas dominated by North America,
Western Europe and the Pacific, effective cooperation is the key to sustained success.
Mr. Lautenberg is a diplomat, whose career has been strongly oriented on bilateral and multilateral economic matters (Poland,
FRG; GATT, EFTA, CSCE). Between 1970 and 1974, Mr. Lautenberg, who holds a degree in political sciences from the University
of Lausanne, led various research programs at the General Staff of the Department of Defense. 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

This paper describes an effort by industry and university partners to centralize manufacturing decision making through the development of generic simulation tools. This ongoing, cooperative process improvement initiative between the Industrial and Systems Engineering faculty at the University of Alabama in Huntsville (UAH) and Chrysler’s Huntsville Electronics Division (HED) permits the involved faculty to broaden their experience and technical expertise in electronics fabrication, while the industry partner benefits from the transfer of technical knowledge and advanced analysis methodologies from the university. The focus of the project is the definition of generic electronic manufacturing models that can be easily defined and implemented through common user-oriented interfaces, allowing users who are not familiar with simulation and simulation languages to address the needs of their particular functional areas. 相似文献
