Evaluating teaching and students’ learning of academic research ethics

A team of philosophers and scientists at Dartmouth College worked for three years to create, train faculty and pilot test an adequate and exportable class in research methods for graduate students of science and engineering. Developing and testing methods for evaluating students’ progress in learning research ethics were part of the project goals. Failure of methods tried in the first year led to the refinement of methods for the second year. These were used successfully in the pilot course and in one university setting external to Dartmouth. The process of development and justification for the final methods are discussed here.     

Positive and negative reinforcement effects on behavior in a three-person microsociety

Three-person groups, either of males or of females, resided for 6 to 12 days in a continuously programmed environment. Subjects followed a behavioral program that determined the sequential and contingent relations within an inventory of activities. The program consisted of positive reinforcement days and avoidance days. During a positive reinforcement day, each work unit completed by a subject incremented a group account. The account was divided evenly among the three participants at the conclusion of the study. During a negative reinforcement day, no money was earned, and the group was assigned work unit criterion that, if completed, prevented a reduction in accumulated earnings. During negative reinforcement days, subjects made aggressive verbal responses, which differed in magnitude among the four groups. These differences were evident in several distinct behavioral measures. Performances on components of the work unit were not demonstrably affected by the reinforcement schedules in effect, although during the avoidance condition one subject stopped working and another subject's productivity declined.     

Parents' Estimations of Preschoolers' Number Skills Relate to at‐Home Number‐Related Activity Engagement

According to Hunt's match hypothesis, the accuracy of parents' beliefs about their children's abilities can influence the nature of the early learning experiences they provide. The present study examined the accuracy of parents' beliefs about their preschoolers' number development and relations to parent‐reported frequency of engaging children in number related experiences at home. Parents reported engaging their preschoolers more frequently in conventional numeracy activities, (i.e. counting and identifying numbers) than advanced number‐related activities (e.g. arithmetic) at home, though the frequency of advanced activities increased with the development of children's advanced number skills. Parents were most uncertain about their children's advanced number skills, though they demonstrated an overall tendency to overestimate their children's abilities across number tasks. Increased rates of overestimation and decreased rates of underestimation were associated with increased incidences of advanced activity engagement at home. Thus, results suggest guiding parents to understand their own children's numerical understanding in a wide range of number domains could promote more advanced at‐home number‐related activity engagement.

企业伦理的德性主义进路及其条件——以所罗门的亚里士多德方式为例

理解企业伦理的德性主义进路不可或缺。美国当代著名经济伦理学家罗伯特·C．所罗门成功地将亚里士多德德性论引入企业伦理学,为人们把握企业伦理提供了一条德性主义的诠释进路。而亚里士多德德性论强调实践、团体、人对幸福的追求和追求卓越等也为企业伦理的德性主义进路提供了思想资源。而美德自身也能够使人们正确地理解商业和商业伦理、使经济交易成为可能、使经济的运行更为成功。但德性主义进路不是没有条件的,它需要个体或企业具有良好的道德价值观念和良好的判断力,也需要规范伦理与之匹配,以及一个尊重美德的社会环境和相关的制度安排。     

大学生学校心理环境问卷的编制

目的:探索大学生学校心理环境的结构并进行问卷编制。方法:通过文献分析、现状分析和专家讨论形成问卷初始结构。在两次试测后,以262名大学生为正式样本进行因素分析、信效度分析和多元概化理论分析。结果:大学生学校心理环境结构包括:师生关系、同学关系、集体活动、专业发展、资源和制度与秩序六个因素。问卷的验证性因素分析结果表明,六因素模型和二阶因子模型拟合度均良好。结论:大学生学校心理环境问卷具有良好的信效度指标,可以作为大学生学校心理环境的测量工具。     

自我损耗对攻击行为的影响:复愈性环境的作用

本研究采用实验(stroop任务和竞争反应时任务)和问卷(积极情感消极情感量表)相结合的方法,探讨复愈性环境对自我损耗后攻击性行为的影响。结果发现:高损耗组反应性攻击行为显著大于低损耗组,两组主动性攻击行为差异不显著;观看复愈性环境和非复愈性环境后,复愈性环境组反应性攻击行为显著低于非复愈性环境组,主动性攻击行为两组无差异。结果表明:自我损耗后会产生情绪上的不良表现,反应性攻击行为增多,而主动性攻击行为不受损耗影响;自我损耗后观看复愈性环境,能够缓解情绪上的不良表现,增加认知资源,从而减少攻击行为。     

"Say it...near the flower shop": further evidence of the effect of flowers on mating

For millennia, flowers have been used to convey romance. In this study, 18-25-year-old women (N = 600) walking alone in a shopping mall were approached by an attractive 20-year-old male-confederate who solicited them for their phone number. The women were solicited as they were walking in the area of a flower shop, a cake shop, or a women's shoes shop. It was found that women agreed more favorably to the confederate's courtship solicitation when solicited in the area of the flower shop. Positive mood induced by exposure to flowers was used to explain these results.     

The General Environment Fit Scale: A Factor Analysis and Test of Convergent Construct Validity

Person-environment fit (P-E fit) was initially espoused as an important construct in the field of community psychology; however, most of the theoretical and empirical development of the construct has been conducted by the industrial/organizational (I/O) psychologists and business management fields. In the current study, the GEFS-a P-E fit measure that was developed from organizational perspectives on fit-was administered to 246 attendees of an annual convention for residents and alumni of Oxford House, a network of over 1,400 mutual-help addiction recovery homes. The authors conducted confirmatory factor and convergent construct validity analyses with the GEFS. The results suggested that the theoretical factor structure of the measure adequately fit the data and provided limited support for the measure's validity. Sufficient supply of resident needs by the Oxford House and similarity between residents and their housemates predicted satisfaction with the recovery home, but only perceived similarity to housemates predicted how long residents intended to stay in the Oxford Houses.     

Power and Legitimizing Ideologies in Hierarchy‐Enhancing vs. Hierarchy‐Attenuating Environments

According to social dominance theory, intergroup dynamics are strongly influenced by the social positions which individuals hold in society. Several studies suggest that holding a position of power can, sometimes automatically, generate negative attitudes and hostile behaviors toward subordinate social groups. However, at present, the studies carried out on these effects of power have not taken into account the influence of the normative context. Based on the distinction made by Sidanius and Pratto between “hierarchy‐enhancing” (HE) vs. “hierarchy‐attenuating” (HA) environments, this study examines if the effects of power on legitimizing cognitions vary as a function of the normative environment. A laboratory study and a study conducted in a natural environment confirm our hypothesis that individuals holding a powerful or dominant social role in a HE setting differ significantly from individuals holding an equally powerful role in a HA setting. The effects of power observed in past research probably resulted from studying power in hierarchy‐enhancing environments, but not in hierarchy‐attenuating ones.
