How provoking! what makes men and women angry?

This study looked at differences in anger-provoking behaviors and in verbal insults as a function of the gender of the aggressor and the target of the provocation. Responses of 416 college students revealed that males were more likely to consider a female exhibiting physical aggression or a male hurting another person as anger-provoking, whereas females were more likely to mention condescending or insensitive behaviors from either sex, verbal aggression from a female, and physical aggression from a male. Physical aggression and hurting another provoked more anger when they came from a male, whereas dishonesty from a female evoked more anger. Females also felt that insensitive and condescending behaviors were worse when they came from a male. Most of the verbal insults were sexual in nature, with few sex of subject differences. However, it was considered worse for women to be called promiscuous; for men to be called sexually inadequate, worthless, or cowardly; for women to call men an obscene name; and for people to be called homosexual by a same sex speaker. These results are consistent both with previous research and with traditional gender role beliefs suggesting that women are more upset by condescending behaviors and that women's promiscuity, as well as men's aggression toward women, hurting another, sexual inadequacy, and cowardice, are viewed particularly negatively. © 1993 Wiley-Liss, Inc.     

Murder most foul: Predictors of an affirmative response to an outrageous question

Male and female students (N = 761) attending university in Canada and the U.S. were asked if they would personally kill someone they knew and thoroughly hated under conditions of anonymity. Among Canadian subjects, males, those who were not religious, foreign students and those scoring high on irritation or assaultive tendencies were most likely to endorse the “murder” item. Among U.S. subjects, only irritability was a significant predictor of the criterion item. The results were discussed in terms of their methodological implications. © Wiley-Liss, Inc.     

Sex differences in cognition among illiterate Bangladeshis: a comparison with literate Bangladeshis and Swedes

We investigated the presence and magnitude of sex differences in late adulthood, assessing 426 illiterate Bangladeshis, 239 literate Bangladeshis, and 598 Swedes. The cognitive domains examined included calculation, episodic memory, spatial visualization, and global cognitive ability. In general, men performed at a higher level than women on tasks assessing calculation and spatial visualization, whereas women performed at a higher level than men on the episodic memory task. Notably, the pattern of cognitive sex differences was similar irrespective of nationality and literacy, although the magnitude of the male advantage was inversely related to level of education. Finally, the low performance of the illiterate women demonstrated the penalizing effect restrictions in public exposure might have on cognitive performance.     

Effects of Violent Video Games on Aggressive Behavior: Potential Sex Differences

Evidence of the effects of playing violent video games on subsequent aggression has been mixed. This study examined how playing a violent video game affected levels of aggression displayed in a laboratory. A total of 43 undergraduate students (22 men and 21 women) were randomly assigned to play either a violent (Mortal Kombat) or nonviolent (PGA Tournament Golf) video game for 10 min. Then they competed with a confederate in a reaction time task that allowed for provocation and retaliation. Punishment levels set by participants for their opponents served as the measure of aggression. The results confirmed our hypothesis that playing the violent game would result in more aggression than would playing the nonviolent game. In addition, a Game × Sex interaction showed that this effect was larger for men than for women. Findings are discussed in light of potential differences in aggressive style between men and women.     

Sex Under Pressure: Jerks,Boorish Behavior,and Gender Hierarchy

Pressuring someone into having sex would seem to differ in significant ways from pressuring someone into investing in one’s business or buying an expensive bauble. In affirming this claim, I take issue with a recent essay by Sarah Conly (‘Seduction, Rape, and Coercion’, Ethics, October 2004), who thinks that pressuring into sex can be helpfully evaluated by analogy to these other instances of using pressure. Drawing upon work by Alan Wertheimer, the leading theorist of coercion, she argues that so long as pressuring does not amount to coercing someone into having sex, her consent to sex answers the important ethical questions about it. In this essay, I argue that to understand the real significance of pressuring into sex, we need to appeal to background considerations, especially the male-dominant gender hierarchy, which renders sexual pressuring different from its non-sexual analogues. Treating pressure to have sex like any other sort of interpersonal pressure obscures the role such sexual pressure might play in supporting gender hierarchy, and fails to explain why pressure by men against women is more problematic than pressure by women against men. I suggest that men pressuring women to have sex differs from the reverse case because of at least two factors: (1) gendered social institutions which add to the pressures against women, and (2) the greater likelihood that men, not women, will use violence if denied, and the lesser ability of women compared to men to resist such violence without harm. I would like to thank Marcia Baron, Sylvia Berryman, Elizabeth Brake, Dominic McIver Lopes, Jennifer Warriner, Janet Wesselius, two anonymous reviewers for Res Publica and the audiences at the University of British Columbia Feminism and Philosophy Workshop and the Western Canadian Philosophical Association meetings in Winnipeg for helpful discussion and comments.     

Sexual and aggressive play fighting of sibling Richardson’s ground squirrels

Play fighting in many species of squirrels can involve sexual play and aggressive play, both of which can lead to wrestling which appears superficially similar. Such convergence can make scoring of the relative frequencies of these two types of play difficult and can lead to the mistaken conclusion that they grade into one another. In this study, both staged laboratory encounters between sibling pairs and spontaneous encounters between siblings in free‐living litters of Richardson’s ground squirrels (Spermophilus richardsonii) were videotaped. Frame‐by‐frame analyses using the Eshkol‐Wachman Movement Notation were employed to record the correlated movements of attack and defense by the partners and to reveal the body areas targeted during each play bout. Whereas sexual play was organized around access to the rump, aggressive play was organized around the shoulders. Although in most cases the defender’s tactics blocked access to the respective target, when contact did occur, it involved mounting in sexual play and nosing or biting in aggressive play. Eighty‐six percent of play fights could be unambiguously categorized as either sexual or aggressive play. Of these, the majority (?80%) involved sexual play. The sex of the participants did not affect the frequency of aggressive play, but in sexual play, males initiated more attacks than females. Once initiated, each form of play fighting remained distinct—if a bout began as sexual play, it would end as sexual play. Furthermore, a counterattack following sexual play was significantly more likely to be sexual than aggressive, and vice versa for counterattacks following aggressive play. Therefore, all the evidence suggested that the two forms of play fighting were not intermixed in Richardson’s ground squirrels. Aggr. Behav. 27:323–337, 2001. © 2001 Wiley‐Liss, Inc.     

对我国儿童肾移植发展的思考与建议

肾移植是儿童终末期肾衰最重要的替代治疗手段。国内数家大的移植中心儿童肾移植长期存活率已接近国外先进水平,但我国肾移植患儿总数较少,主要原因是经费不足和供体缺乏。为推动儿童肾移植的发展,建议建立国家医疗救助制度,鼓励亲属活体肾脏捐献,严格掌握适应证,合理使用免疫抑制剂,加强多中心协作,建立移植随访网络。     

性激素替代治疗在冠心病防治中的作用

冠心病的发病率有着明显的性别差异,大量研究表明内源性雌激素和雄激素与冠心病的发生发展有着密切关系,它对于女性和男性分别有抗动脉粥样硬化作用,这提示人们可以通过恢复机体激素水平达到防治冠心病的作用。因此性激素替代治疗成为了对冠心病的防治研究的热点,本文主要综述性激素替代治疗在冠心病防治中的研究进展。
