Autopsy investigations, toxicological analyses, and calculation of body mass index were performed in 1180 deceased illicit drug addicts (IDAs) in Stockholm. Sweden during 1988-2000, i.e., during a period of time when the general population in numerous countries showed a dramatic increase in the prevalence of overweight. Nutritional deficit in IDAs has been pointed out as a threat to their health as well as to their quality of life. The prevalence of overweight in deceased IDAs increased from 27.4% in 1988 to 45.5% in 2000. The prevalence of overweight among all heroin users, heroin injectors, methadone, cocaine, and amphetamine users was 36.0, 38.4, 43.1, 45.0 and 50.9%, respectively, the lowest prevalence being among users of cannabis alone and HIV-positive IDAs (22.0 and 16.1%, respectively). In conclusion, Stockholm's IDAs are affected by the past decade's dramatically increased prevalence of overweight, at least to the same degree as the general population. The increased body weight seems not to influence the danger of dying upon heroin administration.  相似文献

An 18-month-old child was hit on the head by a falling wooden sculpture (c 60 kg) and sustained a fatal craniocerebral trauma. The kinetics of the trauma could be accurately reconstructed. The child's skull was then modelled using the finite-element-method. The material parameters known from the literature were assigned to the elements. The dynamic reconstruction performed on the basis of the kinetics calculated before was able to reproduce the destruction of the skull and the brain by simulating the impact-related topographical distribution of the intracranial pressure and the von Mises stress field.  相似文献

This paper reports the results of a study of facial tissue depth measurement in White British children of both sexes, aged between 11 and 18 years. The purpose of this research was to increase the information available upon tissue depth data for children, primarily for use in forensic facial reconstruction. Facial tissue depths were measured at 21 anatomical points using ultrasonic echo-location. The mid-philtral, upper lip border and lower lip border points showed consistently larger tissue depths in the males than the females, and the zygomatic attachment showed consistently larger tissue depths in the females than the males. The males showed a general increase in tissue depth with an increase in age at all the mid-line facial points and the cheek points. The females showed increased tissue depth with age at all the points except the infra-orbital, lateral orbital, mid-zygomatic arch and mid-mandibular points. A table of mean tissue depths was developed for males and females divided into two-yearly age groups.  相似文献

This study examined the way late adolescents separate from their parents. Emotional independence and conflictual independence toward mother and father were assessed. Emotional independence was defined as freedom from an excessive need for emotional support from the parents and conflictual independence as absence of guilt, mistrust, and anger toward parents. Students (18–22 years; N = 190) enrolled in higher education completed two scales of Hoffmann's Psychological Separation Inventory. Results indicated that girls more than boys need emotional support from their mothers (z = –3.101, p < .002). They express this need significantly more towards their mothers than towards their fathers (z = –4.194, p < .00003). The pattern of the girls' typical items demonstrated an ambivalence between reported dependence and demand for autonomy. The two types of independence (emotional and conflictual) were moderately correlated (r s = .40). These findings support Gilligan's argument that connectedness plays a central role in the development of female adolescents. They speak for a multidimensional approach of the psychological separation process, which takes the type of independence and the children's and parents' gender into account.  相似文献

This paper examines narratives of assimilation and belonging as activists attempt to position Arab-Americans as citizens and full members of the American polity. In interviews with activists, the experience of the Irish as immigrants and citizens was often invoked as the paradigmatic example of how immigrants are incorporated as citizens—an example that activists promoted as one that Arabs would follow. By invoking the Irish experience, activists hope to remind Americans that immigration history is not one of effortless assimilation, but is rather characterized by systematic exclusion and marginalization. In so doing, they articulate narratives of assimilation and belonging that draw attention to (1) a shared history of immigration, marginalization, and acceptance, (2) the importance of civil rights movements that may seem to distinguish immigrants from a mythic mainstream whose race and ethnicity go unmarked, and (3) the ways in which the American experience is based on the acceptance of cultural differences predicated on shared political values of community. We argue that these strands of the narrative draw on themes in the national myth of immigration, belonging and citizenship, but that they are braided in ways that challenge many Americans’ views of their history.  相似文献
