The disease now called AIDS was first reported among injecting drug users in 1981. This article reviews the last 15 years of research on preventing HIV infection and AIDS among injecting drug users. Many of the findings were surprising in the context of previous understandings of the illicit injection of psychoactive drugs—both with respect to the much-larger-than-expected size of the epidemic and the much-greater-than-expected potential for behavior change among drug injectors (IDU). The research is reviewed within a framework of eight issues: the importance of the problem in the United States, the global diffusion of injecting drug use, the global diffusion of HIV among IDUs, potential rapid spread of HIV among IDUs, risk reduction among IDUs, community-level prevention, syringe exchange programs, and developing a public-health perspective on psychoactive drug use. 相似文献

This essay argues that with respect to trends in Euro-American philosophy there has been a growing disparity between practices on the Continent and North America with respect to technoscience studies. Whereas in, particularly northern European circles, a new canon of topics and authors has risen to prominence with respect to science and technology studies, this same interest is virtually lacking in the institutional programs of North American continental circles. Reasons for the lack of interest in science and technology in North American continentalism are explored. The disparities between Europe and North America include temporal dimensions in which science and technology is read anachronistically in continental circles in North America; canonical dimensions in which different authors are read; and contextual dimensions regarding where technoscience studies occur. There are, however, problem sets such as 'realism and relativism,' 'relations of humans and non-humans,' and roles of 'textuality' which could be seen as overlapping interest areas. The essay attempts to locate and introduce the issues and authors of this 'other' continentally interesting philosophy and recommends that Euro-American philosophers in North America begin to catch up with the newer trends. 相似文献

Female parolees were recruited into a laboratory study to determine the relationship between their previous aggression history, questionnaire measures of aggression, and behavioral measures of aggressive responding using a laboratory methodology: the Point Subtraction Aggression Paradigm (PSAP). Subjects were assigned to a violent or nonviolent group based on their criminal history. Subjects participated in sessions in which they were given three response options: (1) nonaggressive responding that earned money, (2) aggressive responding that ostensibly subtracted money from another fictitious person and was defined as aggressive since it resulted in the ostensible delivery of an aversive stimulus (subtraction of money) to another person, and (3) escape responding that protected the subject's earnings from periodic subtractions initiated by the fictitious other person. Results indicated that the violent female parolees emitted significantly more aggressive responses than subjects in the nonviolent group. This study provides additional external validity as well as evidence for convergent and discriminant validity for PSAP laboratory measurement of human aggressive responding and extends these findings to female parolees. Comparisons to previously published data with male parolees showed that gender differences were found among violent but not nonviolent parolees. Aggr.

The study of sign languages provides a promising vehicle for investigating language production because the movements of the articulators in sign are directly observable. Movement of the hands and arms is an essential element not only in the lexical structure of American Sign Language (ASL), but most strikingly, in the grammatical structure of ASL: It is in patterned changes of the movement of signs that many grammatical attributes are represented. The “phonological? (formational) structure of movement in ASL surely reflects in part constraints on the channel through which it is conveyed. We evaluate the relation between one neuromotor constraint on movement–regulation of final position rather than of movement amplitude–and the phonological structure of movement in ASL. We combine three-dimensional measurements of ASL movements with linguistic analyses of the distinctiveness and predictability of the final position (location) versus the amplitude (length). We show that final position, not movement amplitude, is distinctive in the language and that a phonological rule in ASL predicts variation in movement amplitude–a development which may reflect a neuromuscular constraint on the articulatory mechanism through which the language is conveyed. 相似文献

Neutralization theory posits that criminals assuage feelings of guilt they feel as a consequence of their actions by developing thoughts that justify their deviant behavior. The process is believed to occur prior to the act, and is seen as enabling the deviant behavior. A large body of research has been conducted demonstrating that neutralization “techniques” are used by many criminals. The present work seeks to determine if members of the Animal Liberation Front (ALF) use techniques of neutralization. The method used was a content analysis of anonymous communiqués written by the ALF. The results indicate that ALF members do indeed use various techniques of neutralization to justify their actions, including what may be a newly identified technique, “appeal to a higher moral principle.” Moreover, as the ALF is motivated by a particular ideology, it seems reasonable to conclude that these techniques were developed in the minds of the communiqué authors prior to the criminal actions they perpetrated. 相似文献

Teaching parents how to forgive transgressions of parenting partners may reduce negative emotions, increase positive emotions, and, thus, decrease parenting stress. We implemented a waiting-list design to investigate the efficacy of a 9-hour psychoeducational group intervention, Forgiveness and Reconciliation through Experiencing Empathy (FREE), presented to 27 parents and caregivers of children 0–9 years old. Participants receiving FREE exhibited increased forgiveness of a target offense by the parenting partner and increased forgiveness of all parenting offenses. This study offers initial evidence that an intervention to promote forgiveness and reconciliation in parents could be beneficial and might improve parenting relations. 相似文献

We examined music and language abilities in a group of children with Williams syndrome (WS, n = 19) and a comparison group of normal children (n = 19) equivalent for receptive vocabulary. Consistent with previous reports and the model of Nonverbal Learning Disabilities (Rourke, 1989), the children with WS scored better on verbal than performance measures of the WISC-III, and performance on simpler verbal tasks (e.g., receptive vocabulary) was superior to performance on more complex verbal tasks (e.g., comprehension). Performance on music tests was relatively good, being comparable to mental age based on receptive vocabulary and similar to that of the comparison group. Music and language abilities were moderately correlated for both groups of children. Compared to normal children, the WS group expressed greater liking of music and a greater range of emotional responses to music. 相似文献
