This paper examines the impact of a "disability rights model" on the emerging disability rights movement in Germany. Traditional German disability politics and activism are based on the expansion of welfare and special needs provisions rather than on equal rights and integration. Inspired by the 1990 Americans with Disability Act, German activists adopted a disability rights model and successfully worked toward the passage of a constitutional equality amendment in 1994 and ant-discrimination legislation in 2002. Using the literature on rights mobilization, this paper argues that German disability activists use rights talk to both support and contest culturally specific approaches to disability rights, equal treatment, and the role of the state in guaranteeing welfare rights. The globalization of disability rights should not be viewed as an imposition of American norms but as a more complex process of adaptation and cultural transformation that involves constructing locally legitimate approaches to disability rights with an American import.  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

In the forensic science laboratory, the recovery of spermatozoa from vaginal swabs, or vaginal cells from penile swabs, can help determine if sexual intercourse may have taken place. There are several methods used to recover spermatozoa and cells from the swabs before visualisation on a microscope slide and most of these methods use water. Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis. This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.  相似文献
