There appears to be a strong relationship between mass media portrayals of violence and real-life violence itself. This article
reviews the available literature on the effects of media treatment of sports violence; analyzes the theoretical explanations
for this treatment; and makes proposals on how the problems of both sports violence and its media coverage may be remedied,
with a particular focus on amateur hockey in Canada. 相似文献

A recent clinical study of outpatient psychotherapy groups in a community mental health center explored the linkage between group leadership variables, group climate, and outcome. The study involved nine outpatient therapy groups, over 50 group clients, and several group therapists. A repeated measures design involving assessment of clients' outcome and level of functioning, group leadership style, and group climate was used to assess changes over a 6-month period. The findings suggest: 1) a reduction in symptoms and improved functioning for clients; 2) a similarity of perceptions by members and leaders of perceived leadership behaviors and group climate; 3) the presence of direct and indirect influences of group climate and leadership behavior on clients' outcome; and 4) a linkage between leadership behavior and group climate with the theoretical orientation of the group. The findings of the research are discussed in relation to the understanding of specific effects in group psychotherapy and the implications for construction of group psychotherapy theory.The authors would like to thank Robert Dies, Ph.D., for his helpful suggestions in the early phase of this study; Roy MacKenzie, M.D., for permission to use the Group Climate Questionnaire; Diane DePalma, Ph.D., for permission to use the Global Leadership Behavior Index; Chris Boltwood, B.A., for her untiring efforts in administering the instruments and coding and entering the data; and most importantly, the psychotherapy group members and the group therapists for their cooperation in this endeavor—without their help, this clinical study would not have been possible.A version of this paper was presented at the Annual Meeting of the American Group Psychotherapy Association, 1987, New Orleans, Louisiana. Lenore Phipps, R.N., M.S., C.S., was formerly Director, Group Psychotherapy Program at Park Ridge Mental Health Center, Rochester, now in private practice at Guild Medical Center, Norwood, MA 02062. 相似文献

The present study examined body image satisfaction, dieting tendencies, and sex role traits among a sample of black urban women. While women who felt “too fat” were more likely than other women to engage in both restrictive and nonrestrictive dieting tendencies, in general, the women's body weight and body image did not compel them to utilize extremely restrictive dieting practices. A sizable proportion of the sample reported body image dissatisfaction and weight concerns, yet this did not appear to exert an overwhelmingly negative influence over other aspects of their lives, such as participation in sports, exercise, and sexual activity. Body image satisfaction and sex role traits were related. Dieting tendencies were also related with body image satisfaction. These findings and implications for further research are discussed. 相似文献

This paper describes an amplifier for an electroencephalograph with gain of 1×104 to 1×106 and made entirely of commercially available IC components. The two-stage amplifier has a preamplifier stage with fixed gain of 1000, and a second stage with variable gain from 1 to 100. The final stage, an anti-aliasing filter, adds a gain of 10 to the signal. The circuit has high common mode rejection, low input bias current, very low noise characteristics, low offset voltages, and offset nulling capability built into the circuit. 相似文献

A unique relationship exists between physicians and philosophers — one that expands on the constructive potential of the liaison between physicians and, for example, theologians, on the one hand, or, social workers on the other. This liaison should focus in the scientific aspects of medicine, not just the ethical aspects. Philosophers can provide physicians with a perspective on both the philosophy and the history of medicine through the ages — a sense of how medicine has adapted to the social cultural and ethical needs of each period. This perspective, while emphasizing medicine asscience, should not be limited to matters of methodology, or to criteria for distinguishing science from other intellectual pursuits, but should be concerned also with the history, sociology and politics of science. Both physicians and philosophers stand to gain from a strengthening of their active liaison now as never before; but most of all, the public will be the beneficiary. 相似文献

Fear of Success (FOS) was originally conceived as a unidimensional motive. However, there is both theoretical and empirical
support for the hypothesis that FOS is multidimensional. We factor analyzed the responses of 236 undergraduates to twenty-oneConcern Over the Negative Consequences of Success items and found four factors. Our four factors show considerable overlap with dimensions based on theoretical accounts of
FOS etiology as well as with the factor structures obtained from two other factor analytic studies. Thus, there is converging
evidence that FOS is multidimensional. The relationship between multidimensional FOS and a multidimensional approach to achievement
motivation is discussed. 相似文献

A previous study (Leung, Bond, & Schwartz, 1990) established that an expectancy-valence model could be used effectively to explain behaviours in three social domains both within and across cultures. In this study the model was applied to the domains of resource allocation and conflict resolution in order to pinpoint which expectancies and which valences were carrying the explanatory weight of the respondents' behavioural strategies. For both Israeli and Hong Kong students the expectancies and, less strongly, the valences tapping harmony and performance quality were important for resource allocation; those tapping animosity reduction and process control, for conflict resolution. Suggestions were offered for broadening the net of explanatory constructs for future work aimed at specifying subjective factors associated with justice-related behaviours. 相似文献
