Reformed batterers were interviewed about their perceptions on the nature of their abuse and how they stopped their abuse. The interviewees were 12 men from a men's counseling program who were nonviolent for 10 months or more. The men explained their abuse as a reaction to their failed macho complex. They viewed the counseling program as a reinforcement for their self-determination to change. And they described the process of change in terms of personal growth, in which they accepted responsibility, became empathetic, and redefined their manhood. The implications of the reformed batterer's perceptions for program development are discussed in the conclusion.  相似文献

Tooth fragments freshly extracted from humans and rats were stored at either 4 degrees C or room temperature in dry or humid conditions for periods ranging from 1 to 6 months. The fragments were reduced to powder and antigens were extracted. Comparison of these samples was carried out using Counter Current Electrophoresis. Extracted sera were tested against known specific antisera and resultant precipitin reactions stained for examination. Correct species identification was possible both from desiccated and humid fragments but there was species variation in the sensitivity of the method. All the extracts from human teeth were positive against human antisera. In the rat some test specimens were initially negative but became positive following further dilution of the extracts.  相似文献

Sudden and unexpected death and violent death of persons with a high risk of acquiring HIV-infections, especially homosexual males and intravenous drug abusers, have to be investigated by forensic autopsies. Therefore every forensic pathologist has to be aware of this infection and should try to make the proper diagnosis. Three typical cases are described: (1) suicide by hanging, (2) homicide by cutting the throat and (3) intravenous heroin overdose. Merely retrospectively it could be cleared up that the deceased were homosexual but did not manifestly suffer from AIDS. The morphological findings in the lymph nodes and the postmortem serological findings are described in detail.  相似文献
