Presently more than 80,000 Americans await an organ transplant, while 10 to 12 people die each day because of the lack of organs. The program proposed here would allow federal inmates additional "time off" for agreeing to become living donors or to provide organs or their bodies upon death. Such a program could add 100 to 170 thousand new organ donors to the pool, with another 10 to 12 thousand added annually. If the program were applied to all state inmates, up to 4 million new donors might be added, with another 10 to 13 thousand added annually. Given the extreme need for more organ donors and the need for more living donors, the current National Transplant Act of 1984 and the Uniform Anatomical Gift Act must be amended, while still retaining control of donation procedures.  相似文献

Average faces are attractive, but what is average depends on experience. We examined the effect of brief exposure to consistent facial distortions on what looks normal (average) and what looks attractive. Adaptation to a consistent distortion shifted what looked most normal, and what looked most attractive, toward that distortion. These normality and attractiveness aftereffects occurred when the adapting and test faces differed in orientation by 90° (+45° vs. −45°), suggesting adaptation of high-level neurons whose coding is not strictly retino- topic. Our results suggest that perceptual adaptation can rapidly recalibrate people's preferences to fit the faces they see. The results also suggest that average faces are attractive because of their central location in a distribution of faces (i.e., prototypicality), rather than because of any intrinsic appeal of particular physical characteristics. Recalibration of preferences may have important consequences, given the powerful effects of perceived attractiveness on person perception, mate choice, social interactions, and social outcomes for individuals.  相似文献

Race differences in professional help seeking   总被引:4,自引:0,他引:4  
Using data from two national surveys, findings from this research indicated that blacks were more likely than whites to seek help from mental health professionals, particularly for economic and physical health problems. Blacks also sought help more often than whites from other sources of professional help, such as teachers, lawyers, social workers and emergency rooms. On the other hand, whites were more likely to seek help from medical sources for all types of problems, and from clergy members.  相似文献

College women (N= 125) were surveyed about their experiences with sexual coercion. Forty-two percent of the sample reported one or more coercive incidents involving completed intercourse (26%) or attempted intercourse (16%). Only 6% of these incidents were reported to police or campus authorities. Of the victims, 92% knew their assailants, at least casually. A combination of demographic, sexual history, and personality characteristics predicted 21 % of the variance in experience with sexual coercion. The variables most highly associated with reported victimization were frequency of sexual activity and religiosity; women who were more sexually active and who attended religious services less often were more likely to report experiencing sexual coercion than were women who were less sexually active and who attended religious services more often. A combination of situational and attitudinal variables predicted 52% of the variance in victim attributions. The variables most highly correlated with attributions were degree of victim assertiveness and the type of force used by the assailant; less assertive women and women who had been coerced by the use of economic or psychological force made relatively more internal attributions about the coercion incidents they had been involved in than did women who were more assertive and women who had been coerced by means of physical force. Finally, a combination of situational and attitudinal variables predicted 34% of the variance in victim-reported adjustment problems following the coercion incident. The use of economic or psychological force, greater physical injury, and relative acceptance of interpersonal violence were associated with more severe adjustment problems, whereas the use of physical force, less physical injury, and relative rejection of interpersonal violence were associated with less severe adjustment problems. The implications of these results for the reduction of acquaintance assault and for the counseling of victims are discussed.  相似文献

The knowledge level about HIV/AIDS among American adolescents aged 16 to 19 has been assessed on several occasions, showing that in recent years their knowledge base has improved. The knowledge bases of British adolescents and of adolescents younger than 16 have been largely ignored. In attempting to assess the likely impact on present or future behaviors of increasing adolescents’ knowledge base about AIDS it is important to also know something of adolescents’ attitudes to intimate relationships and to sex within those relationships. Previous studies have not linked these two aspects. In this study two hundred London schoolchildren aged 14 and 15 years completed a questionnaire tapping both their knowledge about HIV infection and its transmission and their attitudes to intimate relationships. Their answers revealed that they had absorbed the simple media messages about AIDS, that it kills and that use of a condom during sex offers protection. However they were less well informed on detailed aspects of prevention, although, worryingly, they believed that they knew all that they needed to about preventive measures. The majority had attitudes to intimate relationships that were compatible with the message of restricting their number of sexual partners; however, a significant minority did not. The latter were more likely to deny the risk associated with promiscuity. It is suggested that school-based AIDS education programs should help individuals to develop new attitudes to intimate relationships that are compatible with risk avoidance.  相似文献

There is much literature on posttraumatic stress disorder (PTSD) and male combat veterans, but little on PTSD by gender and ethnicity among women combat veterans. We examine ethnic differences in PTSD and comorbid disorders among 37 Hispanic, 27 White, and 15 Native female Operaton Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) combat veterans. Participants completed the Clinician-Administered PTSD Scale (CAPS), the Structured Clinical Interview for DSM-IV, Axis I (SCID-Axis I and II), Life Events Checklist (LEC), Military Stress Exposure Questionnaire (MSEQ), and the Medical Outcomes Study Short Form-36 (SF-36). Hispanics differed from Whites in having less education, more trauma exposure, higher levels of PTSD, mood disorder comorbidity, and poorer physical and emotional functioning. Natives differed from Whites with more trauma exposure, higher levels of PTSD, poorer emotional functioning, and higher rates of Cluster B PDs.  相似文献

Structured interviews of ten female studentswith male major professors, ten female students withfemale major professors, ten male students with malemajor professors, and ten male students with female major professors were content-analyzed forevidence of differences related to student-professorgender combination. These quantitative and qualitativecontent analyses indicated no differences inprofessional relationships. However, with respect topsychosocial relationships, there were some advantagesto male students and disadvantages to female studentsassociated with having male major professors. Forexample, compared to other gender combinations, femaleswith male major professors made the greatest number ofnegative psychosocial comments and met with their majorprofessors in the fewest number of nonacademic environments. Males with male major professorsmet in the greatestnumber of nonacademic environmentsand placed their major professors on their lists ofsupportive people most often.  相似文献

Different definitions of sexism have been usedby different experimenters and little attention has beengiven to the possibility that participants' definitionsof sexism might vary across individuals and across situations, just as the definitions ofinvestigators vary. Judgments about sexism areinextricably based on individual perceptions, values,and beliefs. It would seem reasonable, therefore toexamine individual conceptions of what constitutessexism. A total of 95 primarily middle-class Caucasianparticipants (68 females, 27 males) participated inthree studies investigating what information people use in deciding whether or not a male actor issexist. Six specific categories of information (or cues)were examined: (1) comments (or lack thereof) by theactor on a female target's physical appearance, (2) unwanted or inappropriate physical contact(or lack thereof), (3) assumptions (or lack thereof)about the target's work, personality, etc., based on hergender, (4) the target being interrupted (or not) by the actor, (5) an apparent powerdifferential (or lack thereof) between the actor and thetarget, and (6) assumptions by the actor aboutappropriate gender role behaviors. A policy capturingmethodology was employed in which three different sets ofscenarios, each describing a number of interactions(called profiles) between a target and an actor, werepresented to male and female participants who rated the degree of sexism exhibited by the actor ineach scenario. Policy capturing represents anideographic approach to research in which the primaryfocus is on establishing statistical parameter estimates that describe each individual's behavior in avariety of environmental situations. Only when that isaccomplished does the researcher examine the possiblenomothetic aggregations across participants. Thus many fewer participants are required than intraditional nomothetic approaches. Each profile set useda different subset of the cues which contained eithersubtle (Study 1), overt (Study 2), or very overt (Study 3)levels of the cues. Multipleregression analysis revealed that when relatively overtacts of sexism were described, most participants hadreliable policies; that is, their judgments werepredictable from the cues. However, when relatively subtleacts of sexism were described, most participants did nothave reliable policies; that is, their judgments werenot very predictable from the cues. There were large individual differences in howparticipants weighted the importance of various cues,especially with subtle cue levels, and in participants'mean sexism ratings.  相似文献
