Individually measured factors and neighborhood context were related to juvenile delinquency in a community sample of 506 urban, public-school boys. Neighborhood context was measured with an objective, census-based score that classified neighborhoods as underclass or not underclass. When African American youths and white youths were compared without regard to neighborhood context, African American youths were more frequently and more seriously delinquent than white youths. When African American youths didnot live in underclass neighborhoods, their delinquent behavior was similar to that of the white youths. Hierarchical multiple regression analyses showed that boys' hyperactivity and parental supervision were the strongest correlates of delinquency. Single-parent status and poverty/welfare use were not related to delinquent behavior. Once individually measured factors were accounted for, residence in underclass neighborhoods was significantly related to delinquent behavior while ethnicity was not. This study points to the importance of including the neighborhood context when addressing the social problems of African American youths.  相似文献

Inconsistent findings of attitude-behavior relations are commonly attributed to uncontrolled domain, time, or situational factors. Without integrative work, studies accounting for these factors may further complicate research by introducing potentially numerous third variables and render a coherent understanding of the attitude-behavior relationship even more difficult to achieve. In this paper, a developmental perspective is taken and the attitude-behavior relationship in delinquency is examined using three modes of investigation: multivariate patterns of attitude-behavior associations, their mutual predictability, and their developmental trajectories. Three grade cohorts of public school boys (n=1517 of the first, seventh, and tenth grades, initially) were followed over a period of 4 years, with an average age span of 7–16 years. Correspondence analyses suggested that adolescent boys with a tolerant attitude toward theft or violence were more deviant than those who had actual behavior of theft or violence. Stronger attitude effect on subsequent behavior, relative to behavior effect on subsequent attitudes, was found among boys aged 10–12 years. While mean scores of tolerant attitudes to serious theft and violence increased linearly with their behavior counterparts between 6 and 17 years of age, ages 11 and 14 were two turning points at which most delinquent attitudes and behaviors escalated at a higher speed. In general, delinquent attitudes and behaviors were related to each other in various patterns, and age was a defining factor that provided much of the explanation for the inconsistencies in research findings.  相似文献

The glucuronide conjugation is a minor pathway of ethanol metabolism. The determination of ethyl glucuronide (EG) in serum and urine has gained importance in forensic and other legal decisions. To prospectively calculate the serum concentration of this non-oxidative ethanol metabolite, the computer program developed includes a parameter fitting routine. Multiple ethanol doses can be handled.The mathematical modeling was based on the following assumptions and simplifications, respectively. A single enzyme system is responsible for ethanol conjugation at one distinct site; the distribution of EG into the systemic circulation is delayed; the elimination of EG follows first-order kinetics.The concentration of EG was calculated using three kinetic parameters: a rate constant for the first-order formation of EG from serum ethanol, a transfer constant for an obstructed transfer of EG from the formation site (FS) into the central compartment (CC) and an exponential elimination constant.The program was applied to the data collected from 21 drinking experiments. The fitting algorithm optimized the three kinetic parameters, until the sum of concentration error squares of the data points was minimized. The means+/-standard deviation of the rate constant for the first-order formation of EG from serum ethanol was 0.0011+/-0.0006 h(-1), the transfer constant for an obstructed transfer of EG from the FS into the CC was 0.43+/-0.1996 h(-1) and the exponential elimination constant was 3.0+/-1.45 h(-1).Using the range of these parameters, it is now possible to calculate minimum and maximum serum concentrations of EG based on ethanol doses and drinking times. The comparison of calculated and measured concentrations can prove the plausibility of an alleged ethanol consumption. This can be crucial when the serum ethanol concentration (SEC) itself is not meaningful.  相似文献

Robert Ezra Park, der „Kopf“ der Chicago School of Sociology, hat seine Laufbahn bekanntlich als Reporter und Redakteur begonnen, sich an literarischen Werken versucht und sich literarischer Werke als Quelle bedient. Weniger bekannt ist, dass er selber zur Figur einer literarischen Darstellung geworden ist. In „Organized Crimes“ (1984), einem Roman von Nicholas von Hoffman, spielt Robert Park eine tragende Rolle als Soziologieprofessor. Der Artikel geht der Frage nach, woher der Autor seine detaillierten Kenntnisse hat, die bis hin zu Parks Vorliebe für Anzüge aus schwarz-grünem Plaid („…attributed around the department to an allegedly gamey youth spent as an newspaper reporter“) reichen. Die Story des Romans und die Biografie des Autors führen uns auf die Spur. Saul Alinsky, radikaler Community-Organizer in Chicago und Mentor von Nicholas von Hoffman, hatte Ende der 1920er Jahre am Chicagoer Department studiert. „Organized Crimes“ kann also durchaus auch als eine Quelle für die Geschichte des Departments zur Hochzeit der Chicago School gelesen werden.  相似文献

The article describes the case of a 29-year-old woman who was found dead in her apartment on a bar stool with the body being maximally retroflected in the lumbar region, the head hanging down and the feet and hands barely touching the floor. On external inspection of the body the cuff-like distribution of hypostasis on the forearms and lower legs was consistent with the position in which the body was found. There were no signs of foreign intervention. At autopsy massive congestion was found in the internal organs as well as pulmonary and cerebral edema. In the ventral region of the lumbar intervertebral discs superficial hemorrhages were detected. The alcohol content was 3.40 per thousand in the blood and 4.43 per thousand in the urine. As the essential pathogenetic mechanisms responsible for death reduced venous reflux to the heart in combination with postural asphyxia and the influence of alcohol are discussed.  相似文献

The second part of the paper on suicides by gunshots to the head in the presence of witnesses focuses on relevant morphological autopsy findings such as entrance site, signs of close range or contact shots, bullet path etc. and also discusses selected aspects of ascertaining gunshot residues. For the identification of the shooter an integral medicolegal assessment of all the facts including the investigation results and the autopsy findings is essential. However, the morphological findings alone do not allow safe diagnosis, as for example in a homicide the temporal region, which was affected in all our cases, may have been deliberately chosen by the perpetrator as a localization typical of suicide. Thus methods to ascertain gunshot residues on the firing hand (by means of adhesive films and the polyvinyl-alcohol collection method--PVAL) are of great practical importance. In seven cases adhesive films and/or the polyvinyl-alcohol collection method were used. In one case the gunshot residues (GSR) were analysed by means of tape lifts and subsequent scanning electron microscopy (SEM). It was found that especially the combined application of topographical (adhesive tape/PVAL) and cumulative (SEM) methods allowed for the doubtless identification of the shooter, thus usually confirming the suicide. By the example of one case it is demonstrated that without the immediate collection of evidence at the scene objective reconstruction of the event becomes impossible. On the basis of the reported cases recommendations are finally given for a differentiated approach in the medicolegal evaluation of alleged witnessed suicide by gunshot (to the head).  相似文献

A series of studies are presented which examine the relation between parenthood intentions (intend to be a parent and intend to remain childless) and self-concept, mental health, and grade point average in a college student population. The results suggest that college students not intending to have a child tend to be statistically deviant on all the variables examined. Cross-validation results suggest a high frequency of psychopathology among the sample of young intended nonparent college students. Based on the MMPI results, the intention to be a nonparent appears to be associated with general maladjustment, rather than just a deviancy from social norms.Received his Ph.D. from the University of Iowa. Primary interest is parenting attitudes and parent training.  相似文献
