This study investigates gender similarity in the effects of birth order upon political leadership. Town supervisors were the leaders studied as there are a considerable number of women who attain this level of leadership. Questionnaires about birth order and family size were gained from 66 women who were town supervisors in New York State in 1992, and compared to a randomly selected sample of 57 male town supervisors. It was found that women as well as men town supervisors were more likely to have been first born in their families. However, whereas gender does not apparently influence the relevance of birth order for leadership, it clearly does exert an influence on the level of political leadership attained. Women town supervisors gained their positions in towns that were considerably smaller than the towns led by the male supervisors. Discussion concerned the nature of family experiences that contribute to leadership training, including those that may be different for girls and boys. Further research is needed to clarify barriers to female assertion of political leadership at more senior levels, because as this study shows, female leadership is being trained in families.  相似文献

The relationship between perceived session helpfulness and session evaluation was examined in 11 dyads during eight sessions of short‐term counselling. Results based on the Session Evaluation Questionnaire (Stiles, 1980) showed that, for clients, while depth, arousal, and positivity correlated with perceived session helpfulness, only depth and positivity entered a stepwise regression, yielding a multiple correlation of 0.76. For counsellors, while depth and positivity correlated with session perceived helpfulness, only depth entered the stepwise regression analysis, with a correlation of 0.70. Session depth also consistently correlated with change in perceptions of helpfulness from one session to another. Clients had higher depth scores for sessions that both participants rated as helpful. They had lower depth scores for sessions rated as less helpful by both participants or for sessions where participants disagreed in their helpfulness ratings. The centrality of counselling depth in affecting experiences of counselling helpfulness is discussed.  相似文献

Thresholds for the perception of linear vection were measured. These thresholds allowed us to define the spatiotemporal contrast surface sensitivity and the spatiotemporal domain of the perception of rectilinear vection (a visually induced self-motion in a straight line). Moreover, a Weber’s law was found, such that a mean relative differential threshold in angular velocity of about 41% is necessary to perceive curvilinear vection. This visually induced self-motion corresponds to the sensation of moving in a curved path. It is proposed that curvilinear vection is induced when the apparent velocity difference is detectable. The spatiotemporal domain of perception of rectilinear vection and its spatiotemporal contrast surface sensitivity are centered on low spatial frequencies. Concurrently, the values which correspond to the relative differential thresholds of curvilinear vection are low spatial frequencies. Accordingly, the peripheral ambient visual system seems to be involved in perceiving linear vection. It is argued further that the central ambient system might also be involved in the processing of linear vection.  相似文献

The state-dependent model of premenstrual syndrome (PMS) suggests that women's perceptions of daily stressors are affected by menstrual cycle phase. Our objective was to further examine the applicability of this model to perceptions of specific kinds of daily stressors and to explore its generalizability to perceptions involving significant others. Thirty-two undergraduate women, 10 PMS and 22 asymptomatic controls, completed the Daily Stress Inventory (DSI) and the Daily Rating Form (DRF) for 35 days. Questionnaires measuring perceived social support and self-esteem were completed premenstrually and postmenstrually. Results indicated that all women perceived a greater number of stressors as being severe premenstrually as compared to postmenstrually. Furthermore, all women perceived a lesser number of signifcant others as being present in their social support network premenstrually. However, only the PMS women were less satisfied with their social support and had more negative self-esteem premenstrually as compared to postmenstrually. Results are discussed within the context of designing treatment intermentions for women with PMS.  相似文献

Circular definitions,circular explanations,and infinite regresses   总被引:2,自引:0,他引:2  
This paper discusses some of the ways in which circular definitions and circular explanations entail or fail to entail infinite regresses. And since not all infinite regresses are vicious, a few criteria of viciousness are examined in order to determine when the entailment of a regress refutes a circular definition or a circular explanation.I would like to thank Professors Robert Tully, Howard Sobel, and Derek Allen for their constructive comments.  相似文献

This short paper proposes a general computing strategy to compute Kappa coefficients using the SPSS MATRIX routine. The method is based on the following rationale. If the contingency table is considered as a square matrix, then the observed proportions of agreement lie in the main diagonal’s cells, and their sum equals the trace of the matrix, whereas the proportions of agreement expected by chance are the joint product of marginals. The generalization to weighted kappa, which requires an additional square matrix of disagreement weights, both matrices having the same order, becomes possible by the use of the Hadamard product-that is, the elementwise direct product of two matrices.  相似文献

Adult women survivors of incest (n = 68) were compared to other women (n = 93) with respect to several questionnaire measures of manifest anger. The vast majority of the research participants were white, middle class, heterosexual, and Michigan residents. Incest survivors were angrier than other women, both in general and at their parents. Anger toward mother and anger toward father were comparable. Few incest survivors blamed either parent for the incest, except in those speciflc cases where the parent was a perpetrator. Not surprisingly, incest survivors were particularly angry at parent perpetrators when they were held responsible for the abuse. Incest occurred in families where other traumas were present, and the extent of these other traumas was also associated with increased anger at parents. Women who identified with feminism and who had participated in therapy were angrier at their parents than were other women. Therapy implications of these results were discussed.This paper is based on a doctoral dissertation submitted to the University of Michigan by the first author, under the supervision of the second author. The help and encouragement of committee members Margaret Buttenheim, Kathleen Faller, and Sheryl Olson are gratefully acknowledged. Howard Gottlieb, Judith Ballou, Donna Silbert, and Robert Daniels also contributed substantially to this research.Financial support was provided by the Society for the Psychological Study of Social Issues, the Horace D. Rackham School of Graduate Studies, and the Department of Psychology at the University of Michigan.  相似文献
