To investigate effects of maternal separation on reproductive and behavioral outcomes, male Wistar rats were separated from their mothers daily for 3 hr (maternal separation; MS) or 0 hr (control) from postnatal day (PND) 1 to 14. Timing of puberty, reproductive parameters, hormone levels, and aggressive behaviors in juvenile and adult rats were examined. Contrary to expectations, there was no effect of maternal separation on any measure of aggression. However, maternal separation altered peripubertal testosterone secretion and increased mean day of preputial separation. In addition, adult MS males demonstrated less total sexual behavior. There was no difference in sperm counts or testosterone levels at necropsy on PND 56 or in adulthood, but seminal vesicle weights were increased in adult MS rats. These results suggest that early life stress may influence hypothalamic-pituitary-gonadal axis development in males, at least during peripuberty.  相似文献

This study seeks to identify the determinants of turnover intention at women in male- dominated occupations, and namely, attitude-based (job satisfaction and organisational commitment), identity-based (self-efficacy and perceived gender-identity conflict), and context-based factors (perceived social support, induction practices and job design). The survey (N=131) reveals that affective commitment predicts two types of turnover intention: job retention and occupation retention. As regards job retention, affective commitment is related to job satisfaction and job-context structure ; as to occupation retention, affective commitment is linked to self-efficacy and perceived social support material from colleagues and superiors.  相似文献

We conducted an exploratory, qualitative pilot study investigating the use of genetic counseling and prenatal genetic technologies between women and their male partners for two referral groups: pregnant women 35 years of age and over (AMA) at the time of delivery and pregnant women with an abnormal maternal serum triple screen (MSAFP3). The convenience sample consisted of 25 semistructured interviews and 50 observations of genetic counseling sessions. Male partners' styles of decision making and the way they viewed prenatal diagnosis decision making were examined. We defined three decision-making styles based on our interpretation of the data: (1) domain, (2) joint-delegated, and (3) saliency. The male partners also seemed to view prenatal diagnosis as either an information decision or an action decision and appeared to take a more active role in decision making when the decision was viewed as an action decision.  相似文献

Humphreys P  Paxton SJ 《Body image》2004,1(3):253-266
Research examining the impact on adolescent boys of exposure to muscular, athletic, idealised male images has been limited. This research had two aims (i) to investigate the mean effect on state body satisfaction and mood of exposure to idealised male images in adolescent boys, and, (ii) to identify individual attributes that predicted change in state body satisfaction, depression and anxiety following image exposure. One hundred and six boys (mean age=15.6 years) completed a self-report questionnaire on body image attitudes and psychological status. One week later, participants were divided into two groups, one that viewed idealised male images (experimental condition) while the other viewed non-figure advertising images (control condition). Three body satisfaction Visual Analogue Scale (VAS), and a depression and anxiety VAS were completed immediately prior to and following image exposure. In the experimental compared to control condition, there were no significant changes on Want Toned Body, Want to Change Body Shape, Depression and Anxiety VAS following image exposure. However, there was a significant improvement in Like Body Shape VAS. In the experimental group, high internalisation of the muscular, athletic ideal predicted more negative response to viewing images on the body image and Depression VAS. Prior body dissatisfaction significantly predicted negative response to Body Shape Liking and Anxiety VAS. While on average, adolescent boys in this research were not negatively affected by exposure to idealised male images, reaction to exposure is dependent on individual attributes.  相似文献

植入前遗传学诊断中性别选择的伦理辩护   总被引:1,自引:0,他引:1  
植入前遗传学诊断(PGD)是在胚胎植入子宫前进行遗传学检查的新技术。它可对植入胚胎进行性别选择,从而引发了会增加我国出生人口性别比的担忧。通过对PGD性别选择伦理风险的分析,指出其用于医学需要时不会对性别比造成危害。但在实施过程中需要医生、患者及社会全体人员共同参与,避免该技术用于非医学目的的需要。  相似文献

The purpose of this study was to assess the relationship of idealization and three specific intimacy factors (relationship satisfaction, excitement, and closeness) to reported condom use in gay male couples. It was expected that there would be negative associations of idealization and the intimacy factors with condom use. Both members of 45 gay male couples completed a questionnaire that assessed these factors. This study found (a) idealization to have a significant negative correlation with condom use, suggesting that the more the individuals idealized each other, the less likely that condoms were used during sex; (b) a significant negative association between relationship satisfaction and condom use, implying that as the couples experienced more satisfaction within their relationships, condom use decreased; (c) a significant negative correlation between excitement and condom use, suggesting that as excitement increased, condom use decreased; and (d) no significant association between closeness and condom use.  相似文献

肌肉上瘾综合征是指个体对于缺乏大块肌肉的错误认知的先占观念,是近二十年来西方学者的研究热点之一。已有研究从肌肉上瘾的诊断和测量,与体象障碍等心理障碍和行为异常的关系,以及形成机制等方面进行了深入的研究。然而,目前关于其临床诊断、产生机制等方面还存在争议。肌肉上瘾综合征在我国,甚至是亚洲尚缺乏足够的关注度。肌肉上瘾综合征的诊断依据、病征的文化差异、共患疾病、形成机制等将成为今后研究的焦点问题。  相似文献
