监狱警察应对方式与心理健康水平研究 总被引:1,自引:0,他引:1
本文通过对重庆市监狱警察应对方式和心理健康水平的抽调研究,发现调查对象倾向于采取成熟的应对方式,且其心理健康水平优于普通人群,在对应对方式有效性的评价(认识)、采取的应对方式(行为)和心理健康水平(结果)三者之间存在一致性;男女狱警在应对方式和心理健康水平方面都存在一些差异,且差异显著。这提示我们在进行应对方式干预时要注意男女狱警不同的两性特征和角色期望。 相似文献

Nowadays, the criticism of the so-called ‘deficit model’ and the need for ‘upstream engagement’ in science and technology are becoming part of the master narratives of public policies in many countries, especially concerning nanotechnology. This may be considered as a major success for STS scholars, whose research results have largely contributed to this change, especially those concerning the GMO controversies. Some STS scholars thus move from a position of distant and critical observers to the role of experts in social engineering or advisers of policy-makers. However, in their enthusiasm concerning the expected benefits of upstream engagement, institutions, TA practitioners and social scientists seem to ignore some important limitations as well as the implicit framing assumptions of the concept. Based on an experience made by a group of social scientists in the Grenoble area—one of the major ‘nanodistricts’ in Europe—our paper shows that the ‘upstream engagement’ concept is still embedded in a linear model of innovation and is not very useful to anyone pursuing the co-production of innovations. It is especially true when socio-technical networks are already aligned by powerful actors and a worldwide agenda as in the case of nanotechnology. In order to give an opportunity for public engagement to have a larger impact on decision-making, we propose an alternative approach, which combines Actor–Network Theory (ANT), as an analytical tool, with the reflexive and ongoing implementation of public participation. Public engagement is probably one of the critical loci where STS scholars must reflect on the articulation between the knowledge they produce and public policies in action. 相似文献

按学生体质健康标准测试内容及评分标准的规定,连续10年(2002年~2012年)从大连海洋大学学生的体检、体测资料中,每年随机抽取200名(男、女各100名)、年龄在19岁~21岁的样本,探讨其体质健康的变化趋势.统计结果显示,体质及格者、良好者、优秀者的平均增长速度分别为2.4%、-1.2%、-1.9%.可见,大学生体质健康有逐年下降的趋势.建议学校认真落实健康第一的指导思想,加强对大学生的健康教育;对不良的生活方式进行干预. 相似文献

This paper argues that we need to re-think the semantics/pragmatics distinction in the light of new evidence from embedding of irony. This raises a new version of the old problem of ‘embedded implicatures’. I argue that embedded irony isn’t fully explained by solutions proposed for other embedded implicatures. I first consider two strategies: weak pragmatics and strong pragmatics. These explain embedded irony as truth-conditional content. However, by trying to shoehorn irony into said-content, they raise problems of their own. I conclude by considering how a modified Gricean model can explain that irony embeds qua implicature. This leads us to prefer a local implicature model. This has important consequences for how we draw the semantics/pragmatics distinction. 相似文献

The primary purpose of this study was to investigate whether the theory of planned behavior (TPB) mediated the relationship between dialectical thinking and health behaviors. A sample of 285 undergraduates was tested with a dialectical thinking styles scale, health promoting lifestyle profiles, and TPB questionnaires. Structural equation modeling was used for data analysis. Results indicated that all the three dimensions of thinking styles (belief in the connection, acceptance of change, and acceptance of contradiction) exerted significant effects on TPB constructs. Specifically, the connection and the change dimensions had positive effects on health behaviors mediated by TPB, whereas the contradiction dimension had a negative effect. Model 2 showed a satisfactory fit, demonstrating the influential pathways between dialectical thinking and health behaviors. Implications in issues of health promotion and future research are discussed. 相似文献

The author identified profiles of chronic illness knowledge (i.e., heart disease, cancer, diabetes) in a community sample of American adults and examined the effect of sociodemographic influences on relations of illness knowledge to health practices and well-being. Participants were 181 women and 120 men who completed measures of illness knowledge, sociodemographics, personal health practices (e.g., diet, exercise, substance abuse, adaptive healthcare use), well-being (e.g., self-rated physical health, depression, social support), and perceived illness risk. Two-step cluster analyses performed on random subsets of the sample identified three levels of illness knowledge: low, medium, and high. Knowledge groups were differentiated on most measures of health practices, well-being and perceived illness risk. However, effects were substantially attenuated after controlling for differences in age and SES. Findings indicate that age and other sociodemographic factors are related not only to levels of illness knowledge but also to the application of knowledge in relation to health practices and well-being. 相似文献

Content analysis of the sexual fantasies of 87 community college and university students revealed no significant sex differences in the content of sexual fantasies. Both men and women preferred traditional and facilitative fantasies. Because this study was explorative, however, further research is required to validate the suggested scale and replicate these results. 相似文献

In Experiment 1, a study by Messer was replicated with use of 18 children aged 40 to 67 months and nonsense words in which the phonemes of the consonant onsets of permissible and impermissible words were equated for frequency of occurrence. The children did not choose significantly more permissible words at any age, indicating that they did not use phonological rules as a basis for choice. In Experiment 2, similar materials were used with 14 children aged 56 to 74 months. By means of an operant conditioning procedure and a learning set paradigm, an experimental group (five children) was reinforced for choosing the permissible member of 10 permissible/impermissible pairs of nonsense words to a criterion of 80 percent correct responses. On transfer to a test task (16 problems given at a rate of 12 trials per problem) the group reached a mean performance level of 76 percent correct responses, which was significantly greater than that attained by either of two control groups (nine children). It was therefore concluded that some evidence for the existence of implicit phonological rules had been obtained, although the conclusion had to be qualified because (a) the mean level of performance of the experimental group during the test task was relatively low, and (b) because only children with high 1Qs performed at a level better than chance. 相似文献
