The purpose of this study was to examine attitudes toward physical education (PE and PE class preferences of high school Turkish students in terms of school gender composition; 213 girls and 249 boys from coeducational public schools, and 196 girls and 210 boys from single-sex vocational schools participated in the study. The Attitudes Toward Physical Education Scale was administered and the results of 2 x 2 (Gender x School Type) ANOVA indicated that students in coeducational schools in general, and boys had more favorable attitudes. Additionally, chi-square analysis demonstrated significant differences in PE class preferences between students from single-sex and coeducational schools and between girls and boys.  相似文献

American women are stressed by network events and men by economic events outside the home, with women internalizing distress symptoms and men externalizing them. This gender pattern of stress-distress in the United States was tested in the 1990–1991 Czech Republic with a two-wave panel based on 294 households, 90% of which are Czech. This analysis is restricted to the 192 respondents who completed questionnaires in the second wave, 1991. The country was in the shock phase of its transition from state socialism to democracy and a market economy, and people were experiencing economic hardship and uncertainty. Czech women and men reported similar exposure to economic and network stress and were similar in their vulnerability to stress (mastery and social support) as well. Women reported higher levels of internalized distress symptoms (depression, anxiety, and somatization) than men, but there were no significant gender differences in externalized symptoms (hostility). The effects of economic and network stress on the distress symptoms were the same for women and men. Mastery buffered the relationship between economic stress and somatization and hostility, but social support was not a buffer between the stressors and distress, and these were true for both men and women. Interpretations of the results rest on the convergence of gender roles in the Czech Republic since 1948, which exposed Czech women and men equally to the shock phase of the post-communist transformation.Research for this paper was supported by the National Institutes of Mental Health (MH50369), NATO, and IREX, with funds provided by the Andrew W. Mellon Foundation, the National Endowment for the Humanities, and the U.S. Department of State. Partial support was provided by Iowa State University and the Agriculture University of Prague as well. Lorenz was also funded by the Iowa Agricultural and Home Economics Experimentation Station. None of these organizations is responsible for the views expressed.  相似文献

In paper [5] it was shown that a great part of model theory of logic with the generalized quantifier Q x = there exist uncountably many x is reducible to the model theory of first order logic with an extra binary relation symbol. In this paper we consider when the quantifier Q x can be syntactically defined in a first order theory T. That problem was raised by Kosta Doen when he asked if the quantifier Q x can be eliminated in Peano arithmetic. We answer that question fully in this paper.I would like to thank Kosta Doen and Zoran Markovi who made valuable suggestions and remarks on a draft of this paper.  相似文献

This work investigates production preferences in different languages. Specifically, it examines how animacy, competition processes, and language-specific constraints shape speakers' choices of structure. English, Spanish and Serbian speakers were presented with depicted events in which either an animate or inanimate entity was acted upon by an agent. Questions about the affected participant in these events prompted the production of relative clauses identifying these entities (e.g., the bag the woman is punching). Results indicated that in English, animacy plays a strong role in determining the choice of passive structures. In contrast, it plays a less prominent role in Spanish and Serbian structure choices, where more active structures were produced to varying degrees. Critically, the semantic similarity between the agent and the patient of the event correlated with the omission of the agent in all languages, indicating that competition resulted in the agent's inhibition. Similarity also correlated with different functional choices in Spanish. The results suggest that similarity-based competition may influence various stages of production planning but its manifestations are constrained by language-specific grammatical options. Implications for models of sentence production and the relationship between production and comprehension are discussed.  相似文献

This study provides a test of how personality may shape social behaviors in a long-lasting dyad: the parent-adolescent relationship. In a large Belgian community sample, it was examined which parent Big Five characteristics were related to parenting and whether adolescent Big Five characteristics elicited certain parenting behaviors. Further, the proposition that individual differences are amplified under stress was examined by exploring whether parent personality was differentially related to parenting for parents of "easy" versus "difficult" adolescents. Moreover, possible differences in associations across parental and adolescent gender were explored. Mothers (N = 467) and fathers (N = 428) reported on their personality using the Five-Factor Personality Inventory; adolescents (N = 475) assessed their personality with the Hierarchical Personality Inventory for Children. Two types of parenting behaviors, overreactive discipline and warmth, were assessed 2 years later by parent self-reports, partner reports, and adolescent reports, from which multi-informant latent factors were created. Results indicate that parental personality was more relevant than adolescent personality for explaining overreactivity, but parent and adolescent personality were similarly relevant in explaining warmth. Especially parental and adolescent Agreeableness and adolescent Extraversion were important predictors of both types of parenting. Associations between parental personality and parenting were similarly related to parents of easy versus difficult adolescents, and for mothers and fathers parenting daughters or sons. Together, results show that parent characteristics as well as adolescent characteristics importantly affect dysfunctional and adaptive parenting.  相似文献
