Guided by conceptual and empirical work on emerging adulthood, this study investigated the role of closeness to mother and father and behavioral autonomy during adolescence on the development of adult-onset antisocial behavior. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we identified four aggressive (abstainer, adolescent-limited, adult-onset, chronic) and three nonaggressive (adolescent-limited, adult-onset, chronic) trajectories. Members of the aggressive adult-onset trajectory reported higher levels of paternal closeness during adolescence compared to the members of the aggressive chronic trajectory. Maternal closeness and behavioral autonomy did not differentially predict trajectory membership. In addition, members of the adult-onset trajectories were less likely to be employed or in a romantic relationship and reported decreased physical health during emerging adulthood compared to members of all other trajectories. 相似文献

Drawing upon the metaphor of the religious market, this article presents an analysis of the proselytising strategies the Hare Krishna, a new Hindu worshipping community in Ghana, has developed in order to survive in Ghana's competitive religious economy. It demonstrates the creative ways in which the group negotiates the contours of this market, incorporating Pentecostal methods into its preaching culture, exploiting an ongoing debate between agents of African Religions and Pentecostals on the appropriate place of tradition in Ghana, and establishing its credentials as a religion whose culture is compatible with both African religions and Christianity, yet with deeper insights into the mysteries of life. 相似文献

Abstract: Two cases are reported from South Australia, where deaths occurred that were due to single self‐inflicted gunshot wounds to the head in individuals who were visiting indoor firearm ranges. Case 1: A 54‐year‐old man visiting an indoor firing range placed a .357 magnum handgun to his head and fired one shot. Case 2: A 23‐year‐old woman who was being instructed in firearm usage at an indoor firing range placed a 9 mm handgun to her head and fired one shot. In both cases, deaths were due to cerebral laceration with skull fracture. Firing ranges may be utilized by individuals who are seeking weapons for suicide attempts, and suicide may be successfully undertaken at such locations even while a victim is under direct supervision. In jurisdictions, where firearm ownership is strictly legislated, it may be that clubs can inadvertently provide access to firearms for this type of activity. 相似文献

Extraction of human nuclear DNA from feces samples using the QIAamp DNA Stool Mini Kit 总被引:2,自引:0,他引:2
The use of a QIAamp DNA Stool Mini Kit (QIAGEN) for extracting human nuclear DNA from feces samples is reported. This method employs a stool lysis buffer and a unique matrix (InhibitEX tablet) to remove PCR inhibitory substances specific to feces samples. DNA extracted from various amounts of stool and from stool samples exposed to different environmental impacts was successfully amplified and typed using the Profiler Plus Amplification Kit and ABI PRISM 310 Genetic Analyser. 相似文献

At the end of the nineteenth century, infant mortality rates started to fall rapidly in the Netherlands. Unfortunately, not all regions benefited from this development. High infant death in the Roman Catholic provinces of North-Brabant and Limburg has often been ascribed to a growing reluctance of Catholic mothers to breastfeed their infants after 1870. This was supposedly caused by the combination of a strict, prudish Roman Catholic norm prohibiting women from baring their breasts and a refusal to accept new medical insights into healthy childcare. The food given to weaned children was generally of such poor quality that many infants succumbed to gastrointestinal diseases. Consequently, infant mortality rates caused by water- and food-borne infectious diseases would have been higher amongst weaned babies. By using recently digitised municipal cause-of-death registration statistics, it is possible to see if there are, indeed, indications of a shift in breastfeeding patterns after 1870. First, the authors look at infant deaths from all causes to see whether Roman Catholic municipalities underwent a rise in the mortality of children under the age of one. Second, the authors do the same for cause-specific infant mortality from typhus, typhoid fever, diarrhoea, dysentery, acute diseases of the digestive system and cholera. Based on the outcomes, there was no homogenous rise in infant mortality in all Roman Catholic municipalities. Furthermore, there is no indication that infant mortality due to digestive diseases increased uniformly in all Roman Catholic communities between 1875 and 1899. Either some communities were able to counteract the negative effects of a shift towards weaning or changes in breastfeeding patterns were not a specific Roman Catholic phenomenon at all. 相似文献

The EU legislator has been accused of overemphasizing the repressive aspect of law enforcement, while paying less attention to civil liberties, such as fundamental victims' rights. This paper examines the current position of EU crime victims, with a special focus on the execution phase of a criminal procedure. A victimological assessment of (1) the Framework Decisions on custodial sentences and probation measures and (2) the recent EU Victim Directive shows that none of these instruments contains any mechanisms for safeguarding the rights of victims in the post‐trial stage. Regardless of the various praiseworthy efforts to further the emancipation of victims, when it comes to the execution phase, victims' rights are still largely neglected, thereby opening the door again to criticism. Granting victims a right to information and a (non‐influential) right to be heard would already improve matters greatly. A constitutional assessment indicates that Europe is competent to make these changes. 相似文献
