A comparison of the accuracy and reactivity of methods of monitoring male sexual behavior

Two self-report methods of monitoring male sexuality have been compared—an ongoing method in the form of a diary card and one eliciting retrospective reports in the form of a monthly sexuality interview. Male volunteers were assigned at random to three testing conditions: (a) diary card and monthly interview for 3 months (N=29); (b) three monthly interviews (N=18); and (c) pre- and postinterview only, separated by 2 months (N=21). The correspondence among frequency reports, quality ratings, and number of sexual problems as obtained in diary card and interview measures was examined for respondents in the first condition, revealing that coital frequency and quality ratings were generally quite similar in the two modes of assessment. Interview responses for all subjects were examined for the existence of differential reactive effects according to the frequency of the assessment regimen. No differences emerged among conditions, although a trend for all groups over time was identified. Implications of the results are considered for clinical trials monitoring the effects of new contraceptive methods on sexual functioning.This study was supported by the World Health Organization's Special Programme of Research Development and Research Training in Human Reproduction (Project Nos. 76297 and 79003) and was conducted at King's College Hospital, London.     

精子捐赠与伦理

引起男性不育的一个重要原因是无精症、死精症。精子捐赠的出现为这些患者带来了福音,使其享受天伦之乐成为可能,但同时也带来了一系列伦理学、社会学上的问题,包括子代的知情权问题、近亲结婚问题、家庭内部矛盾问题等等。因此要准确认识、运用和完善新的医学技术,并对其进行伦理和法律的规范,防止滥用。     

Influence of dominance on the development of play fighting in pairs of male Syrian golden hamsters (Mesocricetus auratus)

In the highly social rat, male juvenile and adult subordinates initiate more playful contacts with dominant pairmates than vice versa. This study examined the effect of dominance on playful contacts in the relatively asocial golden hamster. Pairs of male hamsters were reared together from weaning, and their play was filmed in the juvenile (28-36 days) and the young adult (60-70 days) stages of development. By the adult stage, it became clear that one pairmate was dominant over the other. The dominant pairmate launched all aggressive attacks (i. e., bites to the lower flanks and rump), and the subordinate pairmate performed all the submissive gesturing (e. g., tail up submissive posture). Playful contact, which in this species involves gentle nibbling of the posterior cheeks, was more frequently launched by the dominant than by the subordinate. This was not only true at the adult stage, but also at the juvenile stage, before dominance-subordination relationships were sharply polarized. Therefore, it would appear that in the relatively asocial hamster, the subordinates tend to avoid playful contact with dominants. This is markedly different to rats, where the subordinates actively seek out and engage dominants in play. This contrast further supports our hypothesis that subordinate male rats use play as a means of maintaining familiarity with dominants. © 1993 Wiley-Liss, Inc.     

男性少年犯与同龄中学生人格特征的比较研究

采用加利福尼亚心理调查表(CPI-RC)对178男性少年犯和219名同龄男性中学生进行了测查。结果表明：(1)少年犯与同龄中学生的人格特征存在显著差异,少年犯的自我确认、社会价值内化、成就潜能、生活和社会态度、自我实现和个人整合水平都较同龄中学生差;(2)在人格类型上,少年犯与同龄中学生亦存在差异,少年犯的人格类型以常规异向居多。     

十五年来中国男性择偶标准的变化

对《中国妇女》1985年至2000年15年间每隔5年选择一年,并在每一季度中选择一期杂志,统计男性刊登的征婚启事,总共得到332例。采用统计学方法进行定量研究。发现中国男性在15年间对自身的人品、财产、相貌的重视程度显著增高,对自身的婚史和事业的重视程度明显降低;对女方的持家能力的重视程度显著增高,对女方的健康和工作的重视程度显著降低。当代中国男性的择偶标准随时间的推移有了明显的变化,但仍受到中国传统观念的影响。     

Valence specific laterality effects in prosody: expectancy account and the effects of morphed prosody and stimulus lead

The majority of studies have demonstrated a right hemisphere (RH) advantage for the perception of emotions. Other studies have found that the involvement of each hemisphere is valence specific, with the RH better at perceiving negative emotions and the LH better at perceiving positive emotions [Reuter-Lorenz, P., & Davidson, R.J. (1981) Differential contributions of the 2 cerebral hemispheres to the perception of happy and sad faces. Neuropsychologia, 19, 609-613]. To account for valence laterality effects in emotion perception we propose an 'expectancy' hypothesis which suggests that valence effects are obtained when the top-down expectancy to perceive an emotion outweighs the strength of bottom-up perceptual information enabling the discrimination of an emotion. A dichotic listening task was used to examine alternative explanations of valence effects in emotion perception. Emotional sentences (spoken in a happy or sad tone of voice), and morphed-happy and morphed-sad sentences (which blended a neutral version of the sentence with the pitch of the emotion sentence) were paired with neutral versions of each sentence and presented dichotically. A control condition was also used, consisting of two identical neutral sentences presented dichotically, with one channel arriving before the other by 7 ms. In support of the RH hypothesis there was a left ear advantage for the perception of sad and happy emotional sentences. However, morphed sentences showed no ear advantage, suggesting that the RH is specialised for the perception of genuine emotions and that a laterality effect may be a useful tool for the detection of fake emotion. Finally, for the control condition we obtained an interaction between the expected emotion and the effect of ear lead. Participants tended to select the ear that received the sentence first, when they expected a 'sad' sentence, but not when they expected a 'happy' sentence. The results are discussed in relation to the different theoretical explanations of valence laterality effects in emotion perception.     

Rethinking deindustrialisation and male career crisis

The decline in manufacturing and growth of service-based jobs has prompted many social theorists to argue that the ability of working-class men to construct meaningful and rewarding careers is becoming ever more limited. Despite using the universal label ‘working class’, the experience of skilled working-class men has been largely ignored. This article explores 26 work history interviews collected from 14 former Royal Dockyard tradesmen in South-East England and 12 of these men's sons and grandsons. Findings from this research challenge the idea that most men were/and are passive victims of industrial change. By contrast, the majority of men in this study managed to carefully adapt to and navigate the transition from industrial to post-industrial work whilst still retaining a ‘linear life narrative’ to give meaning to their evolving careers and lives.     

睾丸微石症和成年男性精子质量关系探究

探讨睾丸微石症及其不同类型（CTM／LTM）和成年男性精子质量之间的关系,分析其相关性,为临床诊疗提供参考。回顾性分析接受精液常规检查并发现精子的41例睾丸微石症患者,并分为经典型睾丸微石症（CTM）和限制型睾丸微石症（LTM）两组进行对比。结果显示,在精子总数、精子总活力、前向运动精子率和不活动精子率方面,两组比较差异有统计学意义（P〈0．05）。相比LTM,CTM对精子质量的影响更明显。不同类型睾丸微石症和成年男性精子质量之间有关联,呈现出负相关。     

Victim Gender,Number of Perpetrators,and Interpersonal Interaction in Stranger Rape: An Analysis of Direct and Moderator Effects

This study examined the direct and moderator effects of number of perpetrators and gender of victim on interpersonal behaviour in stranger rape. Crime scene behaviours representative of hostility, involvement, control, and offender penetration in rape were examined for 496 UK, police‐recorded cases of stranger rape. Cases were grouped according to victim gender (male or female) and number of perpetrators (lone or multiple). This resulted in four groups (lone female, lone male, multiple female, and multiple male) with 124 cases in each. Binary logistic regression and one‐way analysis of variance were used to investigate the relationships between the two predictor variables and 11 criterion variables. Significant direct effects of number of perpetrators were found whereby multiple perpetrator offences were more likely to involve violence and less likely to involve involvement interactions than lone perpetrator offences. Significant direct effects of victim gender were also found whereby male victims were more likely than female victims to experience hostile interactions and be threatened with a weapon and were less likely to experience offender penetration and involvement interactions. Significant crossover interactions were also found for four hostility variables. The utility of the findings are discussed in relation to crime prevention, victim support, and offender intervention.
