男性监控配偶、配偶不贞与精子竞争的关系 总被引:2,自引:0,他引:2

精子竞争是指同一女性产道中两个或两个以上男人的精子相互竞争卵子的过程。女性得到社会承认的性伙伴可能因精子竞争失败而损失惨重,因为女性私通可能引起男性投资于不携带自己基因的后代。过去研究表明进化而来的男性配偶监控策略可以防止女性不贞,减少精子竞争失败的危险。当前研究发现男性与配偶进行性行为后离别时间越久,男性就越采取出其不意地打电话、独占配偶时间、威胁对配偶感兴趣的男性等手段来监控配偶 相似文献

This study of Japanese female serial arsonists examined their crimes and background characteristics. The data were a sample from the national police register containing arson cases resulting in charges in Japan between 1982 and 2005. Serial arsonists were 6% of the arson offenders and 12% of these were female, resulting in 83 female serial arsonist data sets. The mean age was 37.6 years and 43% were unemployed. Nearly half were married. Only 28% had a documented history of mental problems and 22% had a prior arrest, usually for theft (19%). Female serial arsonists are characterised by going to a place near their home with a lighter and setting fire directly to combustible materials. Non‐metric multidimensional scaling was used to analyse 33 variables related to the offences. The arsons could be differentiated in terms of either expressive or instrumental sources of action. Expressive arsons were opportunistic and impulsive acts, motivated by emotional distress. The fires were mostly set close to home. Expressive arsons were characteristic of 66% of the females. Instrumental arsons were often motivated by revenge and involved planned and goal‐directed behaviours. They were committed by 13% of the females. Instrumental arsonists tended to travel further from home. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The effect of conspecific sex on maternal aggression in hamsters was determined by comparing the frequency of aggressive responses by dams continuously housed with either a virgin male or female cagemate during pregnancy and lactation. Dams easily established aggressive dominance over male cagemates soon after pairing, and their aggression was low thereafter for the duration of pregnancy and lactation. The aggression of dams with females, on the other hand, tended to fluctuate with highs during mid pregnancy and mid lactation and lows around birth. When dam aggression was low around birth, female cagemates frequently became aggressively dominant, and several dams lost their litters. The higher aggression of dams toward females than males is probably a reflection of greater intrasexual competition for environmental resources that includes pups. 相似文献

Agonistic interaction may play a large role in shaping the social structure and spatial distribution of rodents such as Clethrionomys glareolus. Aggressive and non-aggressive behaviors of adult bank vole females were investigated with a home cage test during 10 min sessions. The number of attacks was significantly higher in virgin females kept with intact adult males than in singly reared females or those exposed to male urine. Bulbectomy of the tested females completely inhibited the male stimulating effect. This indicates that males influence the behavior of females by activating their olfactory systems. Aggressive behavior in pregnant or lactating females, which is linked to maternal behavior, was also tested. Female bank voles between 11 and 17 days of pregnancy or lactating at 3–4 days or 9–10 days attacked their partners significantly more frequently than virgins did. Females that had direct contact with males, even if they were not fertilized, appeared to be more successful in same-sex competition. Aggr. Behav. 24:53–61, 1998. © 1998 Wiley-Liss, Inc. 相似文献

The effects of gonadal hormones on aggressive behavior in the female bank vole was investigated in 10 min home cage tests. Ovariectomized (ovx) or intact females injected with oil, with progesterone (P), with a mixture of progesterone and estrogen (P+E), or with testosterone (T) alone were confronted in a resident-intruder test with unfamiliar, nonoperated females as intruders. Intact females showed aggressive behavior more frequently than ovx females. Ovx females injected with P, with P+E, or with T made significantly more attacks, and these attacks lasted longer than those observed for oil-treated voles. The results indicate that P, the typical female hormone, is responsible for aggressive behavior in female bank voles; however, only T increased the duration of interfemale aggression. Aggr.

The sequence of estradiol and progesterone is known to inhibit the expression of aggression in female hamsters. Despite the key importance of progesterone in the inhibition of aggression, little is known of the mechanisms through which progesterone may exert this effect. Three experiments were performed to assess the degree to which metabolites of progesterone can affect aggression in female Syrian hamsters. Systemic estradiol treatment followed by injections of either progesterone (300 μg IP) or 4‐pregnen‐21‐ol‐3,20‐dione (DOC, 300 μg IP) reliably inhibited aggression. Systemic injection (75, 150, or 300 μg IP) of either 5α‐pregnan‐3α,21‐diol‐20‐one (THDOC) or 5α‐pregnan‐3α‐ol‐20‐one (3α,5α‐THP) did not affect aggression. Intracerebroventricular infusion of 3α,5α‐THP following systemic estradiol treatment also did not affect aggression. In a third experiment, female hamsters were given systemic treatments with estradiol and progesterone that were subthreshold with respect to inhibition of aggression. In these females, intracerebroventricular infusion of THDOC inhibited aggression. These results indicate that metabolites of progesterone can inhibit aggression, most notably in synergy with progesterone itself. Aggr. Behav. 27:372–381, 2001. © 2001 Wiley‐Liss, Inc. 相似文献

Presentation of a natural predator, a cat, was used to differentiate elements of maternal attack by female rats on a male intruder. Following exposure (without direct physical contact) of post-partum females to a cat or to a toy stuffed cat (control group), the females were replaced in their home cages and presented with a male intruder rat. Cat exposure reliably decreased lateral attack to the intruder, as well as locomotion, but had no effect on either jump attack or an upright defensive posture (boxing). Since predator exposure produces a somewhat durable increase in defense, along with inhibition of nondefensive behavior, these results suggest that maternal aggression represents a mixture of offensive, usually related to competition, and defensive (protective) behaviors. The results indicate that maternal aggression, as a parental care behavior, appears to be at least partially resistant to fear. © 1996 Wiley-Liss, Inc. 相似文献

研究对10名女性医务社会工作者进行了深度访谈,运用扎根理论的方法分析访谈资料。研究发现:女性医务社会工作者在情感体验和整饰中呈现出医务情境下的情感传递和专业场域下的情感抑制之间的多元矛盾;存在着专业缝隙中的无权感、需求回应时的无助感和工作环境中的无力感表现出来的职业倦怠;情感能量来源于专业赋能和自我赋能,并能够对其进行正向转化,在工作中充分发挥女性特质中的优势和同伴支持进行情感调适。

“THESE ANXIETIES ARE NOT MINE”: ADOLESCENCE,THE OEDIPAL CONFIGURATION,AND TRANSGENERATIONAL FACTORS 下载免费PDF全文
Part 1 of this paper draws on the film Back to the Future (1985) to highlight various aspects of adolescence, the oedipal situation, and transgenerational factors. The authors then discuss the Oedipus myth and its themes of adolescence, narcissism, identity, acting out, repetition, aggression, and the parent–child relationship, among others. Comments drawn from Winnicott's writing on oedipal issues are discussed as well. As an illustration of some of these issues, in Part 2, the authors present the clinical case of Osvaldo, age sixteen. Transference‐countertransference issues in this treatment are explored in depth. 相似文献
