Although universal definitions are by no means agreed upon, the terms sex—male and female—and gender—femininity and/or masculinity—are semantically dissociable. The aim with the current study was to explore whether and to what extent they may be dissociable in perceptual terms. A comparison of sex judgments and gender judgments from point light walker (PLW) stimuli offered possibilities for obtaining a finer-grained picture of the basis or bases of these types of social judgments. In this study PLWs were used explicitly to examine the pattern of responses to questions of sex (male/female) and gender (masculine/feminine). Observers perceived targets to be feminine at the same rate as female, but perceived a subset of targets significantly more often to be male than masculine. Thus, a disconnect was demonstrated between male and masculine perceptions with no such uncoupling evident for perceptions of female and feminine. This pattern of responding accords with the idea—often described as Precarious Manhood—that manhood, or masculinity, may be a more difficult mantle to earn than mere ‘maleness’, with femininity considered closer to an essential aspect of being female.  相似文献

This article demonstrates statistical models to quantify the interaction between a carbamate insecticide and acetylcholinesterase. Carbamates are a class of chemicals that inhibit the activity of acetylcholinesterase in humans, an enzyme involved in the regulation of the neurotransmitter acetylcholine. Following exposure to a carbamate insecticide, we specifically address (1) if acetylcholinesterase activity recovers to its level of preexposure activity; (2) the level of inhibition of acetylcholinesterase activity; (3) the recovery time of acetylcholinesterase activity to its preexposure level for a typical individual; and (4) the upper percentiles of the recovery time of acetycholinesterase activity across individuals. A nonlinear mixed-effects model is fitted to data from a repeated measures experiment conducted with human volunteers randomly assigned to a control and four dose groups. Repeated measurements were taken prior to exposure and at 1, 2, 4, 6, 8, and 21 hours after exposure to the carbamate aldicarb. It was found that full recovery did occur. Inhibition at 1 hour was estimated with maximum inhibition most likely occurring prior to 1-hour postexposure. In addition, recovery was rapid even for sensitive individuals. Given this information, the potential effect from exposure to a carbamate consumed in the diet during a day can be quantitatively assessed.  相似文献

Infant social inhibition is associated with increased risk for anxiety later in life. Although both genetic and environmental factors are associated with anxiety, little empirical work has addressed how developing regulatory abilities work with genetic and environmental risk to exacerbate or mitigate problem behaviors. The current study was aimed at addressing this gap in research by investigating an early emerging regulatory behavior, attention control, in association with genetic and environmental risk for anxiety. Participants included 9‐month‐old adopted infants, their birth mothers, and adoptive parents (N = 361). Lifetime diagnosis of birth mother social phobia was obtained using structured interviews. Adoptive parents completed self‐report measures of anxiety symptoms. Infant social inhibition and attention control were coded during a stranger interaction and a barrier task, respectively. Neither adoptive nor birth parent anxiety was directly associated with social inhibition. The association of attention control with social inhibition in infants was moderated by birth and adoptive parent anxiety symptoms. When infants of birth mothers with social phobia were raised by adoptive parents with high self‐reported anxiety symptoms, greater attention control was associated with greater social inhibition. However, when raised by adoptive parents with low self‐reported anxiety, greater attention control was associated with less social inhibition.  相似文献

ABSTRACT

Despite the spectrum of available resources, homelessness is a persistent societal and public health challenge throughout the United States and in San Diego County. Beginning in January 2014, San Diego began the integration of a Coordinated Entry System into its homeless system-of-care. This historical prospective study examined the predictors of establishing eligibility for permanent housing resources among 15,042 single homeless adults enrolled in the Coordinated Entry System Multivariable logistic regression was conducted to assess the relationship between client vulnerability as measured by the triage tool VI-SPDAT and establishing client eligibility for permanent housing. Overall, being of moderate or high vulnerability was associated with establishing eligibility for a permanent housing resource. Veterans established eligibility faster and more frequently than others, regardless of their vulnerability score. However, the demand for services far outweighed the ability of the system to respond to those with moderate to high vulnerability. More housing navigators and fewer client “hand-offs” between housing professionals are recommended to increase the efficiency of the process. Additional research examining the second and third steps is also needed to more fully understand the factors that promote permanent housing solutions for those seeking services.  相似文献

This paper examines a segment of the activity of smokejumping—the aerial deployment of forest fire fighters—for clues as to how cognition is distributed among the participants. Unlike the Cartesian paradigm in which actors are portrayed as individuals who send and receive messages, the collective nature of developing a shared vision of the environment is emphasized. A shared vision of the environment is vital to the success of the smokejumping activity. It is achieved here through both the use of common reference points in the environment and through historically constituted artifacts designed for the sharing of visions. Thus, human activity can be seen as a collective, historical process.  相似文献

海洋保护区(MPAs)与海洋功能区划的社会目标和生态目标若要实现,必须得到利益相关方的理解。本文以游憩机会序列(ROS)和游憩冲突模型为基础,考察了加拿大不列颠哥伦比亚海洋保护区里面的游艇者。笔者在夏季对到访该地区的游艇者(n=543)进行了问卷调查。调查结果显示,游艇者对环境的偏好各异,证明应该以游憩机会序列为基础进行海洋保护区规划与海洋功能区划。站在游艇者这一群体的角度,他们最看重的是自然环境,帆船驾驶者比汽艇驾驶者更倾向于自然和安静的环境,而汽艇驾驶者则比帆船驾驶者更倾向于以建成设施和采掘活动为特征的环境。有些海洋活动则成为游艇者冲突的根源,包括私人船只、商业赏鲸船只以及贝类水产养殖。本文通过分析指出,有些冲突可以通过海洋功能区划解决,而另外一些最好是通过教育和沟通的方式。文末还针对海洋保护区的管理及未来的研究方向提出了建议。  相似文献
