The attitudes of students toward technologies related to conception were assessed in 1984 and again in 1999. It was expected that increased routinization of such technologies over time would result in higher approval ratings in the second survey. This hypothesis was not supported by the results; there were no changes in approval for most methods that were included in both surveys, and in some cases, approval decreased. It was also hypothesized that methods included in the 1984 survey would receive higher approval than would newer technologies added in 1999, and this was supported by the data. Differences in approval of specific items were found by the gender and religion of respondents. Results suggest that methods involving donors continue to be unacceptable to most students, that the \"older\" methods are not becoming more acceptable, and that newer methods (gestational surrogacy, egg donation, and cloning) are even more problematic.  相似文献

Research has consistently shown a link between alcohol use and partner violence (PV). Little is known concerning the strength of this association across cultures and genders, and few have assessed possible mediators. This study assesses the link between binge drinking and PV among 7,921 college students in 38 sites around the world, and investigates the mediating role of antisocial traits and behaviors (ASTB). A significant association was found between binge drinking and PV, the strength of which differed by site but not by gender. ASTB fully mediated this association. The mean level of binge drinking at each site did not significantly influence the strength of the association between binge drinking and PV.  相似文献

The paper reports results from analyses of the physical aggression against dating partners by four samples of university students in Ciudad Juarez, Mexico, Mexican Americans and Non-Mexican Whites in El Paso and Lubbock Texas, and New Hampshire (N=1,544). The percent reporting partner violence (PV) was high in all samples, but also differed significantly between samples. The lowest rate was in New Hampshire (29.7%), followed by Texas, Non-Mexican Whites (30.9%), Texas Mexican American (34.2%), and the highest rate was in Juarez (46.1%). When only severe assaults were compared, the differences between samples was similar, i.e., lowest in New Hampshire and highest in Juarez. In all four samples, there was no significant difference between males and females in either the overall prevalence of physical aggression or the prevalence of severe attacks. Among the 553 couples where one or both of the partners were violent, in almost three quarters of the cases (71.2%) there was gender symmetry in the sense that both partners engaged in this type of behavior. When only one partner was violent, this was twice as likely to be the female partner (19.0%) as the male partner (9.8%). Among the 205 couples where there was an act of severe aggression, symmetry was less prevalent (56.6%), but when only one partner was violent, it was again twice as likely to be the female partner (29.8% female only versus 13.7 male partner only). These results are consistent with the gender symmetry in PV found in many studies. They extend those results by showing that gender symmetry prevails in four different cultural contexts. The presence of gender symmetry in these different cultural contexts, combined with studies showing that women are injured more often and more seriously by partner-assaults, and studies showing that women initiate PV as often as men, suggests that programs and policies aimed at primary prevention of PV by women are crucial to ending PV and for reducing the victimization of men and women.  相似文献

In recent years, robotic animals and humans have been used to answer a variety of questions related to behavior. In the case of animal behavior, these efforts have largely been in the field of behavioral ecology. They have proved to be a useful tool for this enterprise as they allow the presentation of naturalistic social stimuli whilst providing the experimenter with full control of the stimulus. In interactive experiments, the behavior of robots can be controlled in a manner that is impossible with real animals, making them ideal instruments for the study of social stimuli in animals. This paper provides an overview of the current state of the field and considers the impact that the use of robots could have on fundamental questions related to comparative psychology: namely, perception, spatial cognition, social cognition, and early cognitive development. We make the case that the use of robots to investigate these key areas could have an important impact on the field of animal cognition.  相似文献

Modern contractarians ground morality on preferences that are “considered' to the requisite degree. This move is inadmissible for contractarians. If what counts as a considered preference is external to the agent's estimations, it robs the requisite (to contractarians) motivational force for agents to be moral. There is also a danger of begging the question by grounding morality on pre-approved motives. If the determination of considered preferences is subjective, on the other hand, then a considered preference can be none other than a preference held presently by the actor—whether or not it will sustain sufficient reflection. If so, the introduction of ‘considered’ preferences is idle. Either way, it's bad.  相似文献

Mothers' distress is a correlate of their children's elevated behaviour problems and symptoms. Parenting practices have been shown to mediate these associations, but few studies have observed parenting or focused on parents at risk of child abuse. In this study of 269 high‐risk mothers and their young children (M = 4.2 years), structural equation modelling was used to test associations between mothers' distress and child externalizing and internalizing symptoms. Associations were expected to be partly indirect via mothers' observed low sensitivity, and child gender was expected to moderate associations. Also, mothers' child abuse risk was examined as a unique correlate of sensitivity and children's symptoms, and a moderator of associations of distress with sensitivity and symptoms. Associations showed a pattern of gender‐moderated mediation with the link between mothers' distress and internalizing mostly direct for boys, and equally direct and indirect via sensitivity for girls. The association of mothers' distress with externalizing was mostly direct for boys and girls. Mothers' child abuse risk was not uniquely associated with sensitivity or symptoms and did not moderate any associations. There were no differences in model paths between mothers referred from child welfare/mental health compared with other sources or self‐referred. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

While there is evidence that knowledge influences understanding of health information, less is known about the processing mechanisms underlying this effect and its impact on memory. We used the moving window paradigm to examine how older adults varying in domain-general crystallised ability (verbal ability) and health knowledge allocate attention to understand health and domain-general texts. Participants (n = 107, age: 60–88 years) read and recalled single sentences about hypertension and about non-health topics. Mixed-effects modelling of word-by-word reading times suggested that domain-general crystallised ability increased conceptual integration regardless of text domain, while health knowledge selectively increased resource allocation to conceptual integration at clause boundaries in health texts. These patterns of attentional allocation were related to subsequent recall performance. Although older adults with lower levels of crystallised ability were less likely to engage in integrative processing, when they did, this strategy had a compensatory effect in improving recall. These findings suggest that semantic integration during reading is an important comprehension process that supports the construction of the memory representation and is engendered by knowledge. Implications of the findings for theories of text processing and memory as well as for designing patient education materials are discussed.  相似文献

The United States Coast Guard Academy seeks to develop leaders of character to become officers and manage its numerous missions. During training, cadets receive multiple stressors from their academic, military, and athletic responsibilities, not to mention the social stressors of friends and family. To become leaders of character, cadets need to effectively manage these stressors. This study reviewed cadets' motives leading to effective and noneffective stress management techniques they employed. During the winter of 2008, cadets described their stressors and stress reduction techniques (restorative events) and evaluated their efficacy based on the factors of attention restoration theory (ART). Discriminant analysis identified several motives associated with restorative events; however, many of the common events employed by cadets did not include components of ART, indicating that these events may not be effectively mitigating stress. A follow-up logistic regression indicated that stress reduction was based on restorative events performed to escape routine and role overloads, provide achievement, teach or share skills, and enjoy nature. Events affording low restoration involved motives of physical rest, learning, and physical fitness. Recommendations to improve cadets' stress management are discussed.  相似文献
