Small groups are called upon to make important policy decisions under a wide variety of procedural constraints. ACPE is a flexible, computerized system for conducting small-group voting experiments. It permits researchers to examine the impact of electronic communication on group deliberation and choice. The system runs under a variety of different personal computer networks and is designed to permit the specification of voting rules, communication, and group sizes. The system also facilitates the study of group process by tracking all messages sent and votes taken. An experiment in which the system was used is briefly described. 相似文献

Six hens responded on concurrent variable-interval (key-peck) variable-interval (door-push) schedules of reinforcement in which the second-order (fixed-ratio) requirements on the alternatives (Experiment 1) or the required door forces (Experiment 2) were varied. The key-peck and door-push response (measured as fixed-ratio completion) and time data were well described by the generalized matching law. However, the manipulations of fixed-ratio requirement and required response force differed in their effects. The manipulations of fixed-ratio size affected the response and time measures differently, producing fairly constant, multiplicative biases only in terms of response allocation. It was argued that variations in fixed-ratio size necessarily change the time allocated to that response unit, and thus changes in time bias were not necessarily a fundamental effect of changing the ratio. In contrast, the changes in response bias were a fundamental result of changes in ratio size. The response-force manipulations produced similar bias shifts in terms of response and time allocation, but they appeared to combine with relative reinforcement rate to affect choice interactively. Specifically, behavior appeared to be biased towards the least effortful (i.e., key-peck) response, but the increases in door force had a larger effect on bias when the hens were making this response infrequently (on a lean schedule). The different effects of the fixed-ratio and response-force manipulations on concurrent performance were partially accounted for by the differing times required to complete each response unit under those manipulations, but this would not account for the interaction. The interaction would be consonant with increased response effort decreasing the effective value of the associated reinforcement schedule. 相似文献

The present study explores women’s ideals for masculinity in different social contexts (work, family/romance, and friendship) and compares how traditional (agentic) and non-patriarchal (communal) masculinity are valued in each context. Survey data were collected from one international (N = 159) and three South African samples (Ns = 86, 100, 161) of women. Results show that although women value patriarchal ideals for masculinity, agentic and communal versions of masculinity are valued differently across contexts. Specifically, traditional agentic versions of masculinity were most valued in the contexts most important to the long-term production of viable identity (family/romance and work). It was only in friendship that non-patriarchal communal masculinity was consistently idealized over traditional agentic masculinity. The results are discussed in relation to hegemonic masculinity (HM) and system justification theory (SJT). Congruent with SJT, women idealized versions of masculinity that may not be in their own or their group’s best interests, but in line with HM, the results emphasized the fluidity of masculinity and that the same individual can simultaneously idealize different versions of masculinity depending on the context. Because stereotypes are both explanations for the status quo and warrants for behaving in one way or another, these collective ideals for masculinity and contextual boundaries may be important obstacles to achieving gender equity. 相似文献

We examined gender differences in supervisor ratings of overall job performance and 37 performance dimensions. Based on data from a large, diverse sample of managers (N = 3,367) and nonmanagers (N = 9,670), we found that gender had only minimal effects on ratings for a small number of specific job performance dimensions. This was generally true regardless of whether the job performance dimension was more agentic or communal in nature, whether the job was a managerial or a nonmanagerial position, and regardless of the proportion of men or women that traditionally occupy a specific job. Overall, our results are more consistent with the gender similarities hypothesis than the agency/communion paradigm, role congruity theory, and the lack of fit model. We discuss future research avenues and implications. 相似文献

The use of sperm donation by single women has provoked public, professional and political debate. Newspapers serve as a critical means of both broadcasting this debate and effecting a representation of this user group within the public sphere. This study uses the theory of social representations to examine how single motherhood by sperm donation has been represented in the UK news over time. The study sampled news coverage on this topic in eight British newspapers during three 4‐year periods between the years 1988 and 2012. The dataset of news reports (n = 406) was analysed using a qualitative approach. Findings indicated that UK media reports of single women using donor sperm are underpinned by conventional categories of the ‘personal’, the ‘traditional’ and the ‘natural’ that when paired with their corollaries produce a representation of this user group as the social ‘other’. The amount of coverage on this topic over time was found to vary according to the political orientation of different media sources. Using key concepts from social representations theory, this article discusses the relationship between themata and anchoring in the maintenance of representations of the social ‘other’ in mass mediated communication. Findings are explained in relation to theoretical conceptions of the mass media and its position within the public sphere. It is argued that the use of personal narratives in news reports of single mothers by sperm donation may have significant implications for public understandings of this social group. © 2016 The Authors.

Prospective memory is remembering to carry out a behavior on a particular occasion or at a specific time in the future. This form of remembering is critical for the daily functioning of children with autism spectrum disorder (ASD) and their functional independence from caregivers. We used a single-subject design to investigate whether reinforcement increased the accuracy of prospective remembering in the context of a computerized board game, Virtual Week, of four 6- to 7-year-old children diagnosed with ASD. Reinforcement increased accuracy for all participants compared to baseline performance and effects were maintained after reinforcement was discontinued for three of four children. This is the first study of which we are aware to use a reinforcement-based behavioral intervention to improve the prospective remembering of children with ASD. Limitations and areas for future research are discussed. 相似文献

I presented the following case to my leader-led peer supervisiongroup twice as the case evolved over the course of one year. During my firstmeetings with Mr. and Mrs. M we discussed a prenatal diagnosis of a skeletaldysplasia at thirty-three weeks of pregnancy and the option of a third trimesterpregnancy termination. One year later I presented follow-up on the outcome ofthe affected pregnancy, a new pregnancy, and Mrs. M's suicide. Although bothsegments of the case were completed by the time I presented, my peersupervision group was invaluable. With the encouragement and support of groupmembers, I could openly express and process my sadness and grief for the M'ssituation and the loss of Mrs. M's life. 相似文献

This essay explores pedagogical practices and ethical obligations in the embrace of cultural and religious diversity by a faculty team in a theological school course. Attention is given to the interplay of art and ethical dilemmas in an educational praxis that calls into question students’ taken‐for‐granted worldviews and theologies. In the first of three sections the writers identify several assumptions they brought to the conduct of the course regarding diversity, art, and pedagogy. The second section describes student encounters with and responses to art from a variety of cultural contexts. The paper concludes with a critical reflection on ethical and political issues arising from pedagogical practices that engage students with art. 相似文献
