专科师范生应付方式的特点及其与领悟社会支持的关系   总被引：1，自引：0，他引：1  

左占伟  茹蓉芳  陈瑞瑞 《石家庄学院学报》2010,12(3):93-96

使用应付方式问卷和领悟社会支持量表对600名专科师范生的调查发现,调查对象有3种基本的应付方式类型：问题解决-求助型、退避-自责型和混合型;不同性别调查对象应付方式的类型分布差异显著（χ2=10.61,P〈0.01）,不同性别调查对象在应付方式问卷的＂解决问题＂、＂求助＂、＂合理化＂3个方面平均分差异显著（t=2.58～4.30,P〈0.01～0.001）;应付方式类型不同的调查对象,其领悟社会支持3个方面平均分及总分差异显著（F=9.12～38.05,P〈0.001）.多数专科师范生的应付方式比较成熟,其应付方式与领悟社会支持状况有紧密联系.  相似文献

袁钰 《山西大学师范学院学报》2010,(3):35-38

1895～1937年,随着通商贸易的日渐增多,华北农村社会经济有了一定程度的发展,农民的生产活动也纳入了市场体系之中,农民与市场的关系变得日渐紧密起来。受诸多方面因素的影响,这种关系带有自己一些固有的特征,即迟滞性、被动性、不稳定性和农民社会流动的频繁性。  相似文献   

中学生的人格五因素、感知的社会支持与自尊的关系   总被引：6，自引：0，他引：6  

邹泓  张春妹 《北京师范大学学报(社会科学版)》2006,(4):44-52

以北京和西安1432名初一、初二、高一、高二的中学生为对象,采用小五人格学生问卷、社会关系网络问卷、Rosenberg整体自尊量表,综合探讨中学生的人格五因素、感知的社会支持与自尊的关系。结果发现:(1)人格五因素中的情绪性、开放性,感知的社会支持中的社会性支持、冲突惩罚、满意度对中学生的自尊具有显著预测作用;(2)在人格与社会支持对中学生自尊的联合作用中,人格的作用更为显著,因而是主要的;(3)中学生的人格特征会直接影响自尊,也会影响感知的社会支持,从而间接影响自尊;(4)对男生和女生的自尊产生影响的人格特点和感知的社会支持特点不同。本研究对于促进中学生自尊和心理健康水平的教育实践具有理论指导意义。  相似文献   

Improving sexual health for young people: making sexuality education a priority     

Janet Helmer  Kate Senior  Belinda Davison  Andrew Vodic 《Sex education》2013,13(2):158-171

How well do young people understand their developing sexuality and what this means? This paper reports on findings from the Our Lives: Culture, Context and Risk project, which investigated sexual behaviour and decision-making in the context of the everyday life experience and aspirations of Indigenous and non-Indigenous young people (16–25 years) in the Northern Territory, Western Australia and in South Australia. Using qualitative data, this paper focuses on what participating young people thought was necessary to improve the quality of sexuality education. Participants suggest that current forms of sexuality education are too clinical, didactic and unengaging, and are missing in relevant content. Young people requested more information on relationships, first sexual experiences and negotiating condom use. These requests indicate that young people realise that they need more knowledge in order to have healthy relationships, which conflicts with the popular belief that providing young people with open, honest information around sex will encourage them to have sex or increase sexual risk taking. Making sexuality education more of a priority and listening to the needs of young people could be a positive step towards improving sexual health and well-being.  相似文献   

知觉价值、社会影响、自我认同与进口名牌包购买行为之研究     

李宏安  方慧臻 《武汉职业技术学院学报》2013,12(3):30-38

在文化、创意、美学意识盛行的现代社会,对年轻的消费族群而言,注重的不仅仅是产品的实用面及基本需求,"个人品味"也是重要的要求,产品的外型、美观、品牌、包装、设计感都列入购买考虑。国际精品名牌包的消费则是现代年轻人展现自我品味的表现。但青少年阶段在群体意识上表现又特别的强烈,故在精品购买决策上又会受到社会性的影响。年轻人对于进口名牌包的消费与影响其消费的因素相当复杂,值得深入的探讨。通过探讨知觉价值、社会影响、自我认同等因素对青少年购买进口名牌包之影响,发现青少年的精品消费有很强的社会性影响,不论是规范性或信息性。但青少年也不会一味地追求炫耀或展现财富而去采购高知名度的名牌包。  相似文献   

Prospective teachers’ perceptions of instrumentality,boredom coping strategies,and four aspects of engagement     

Altay Eren 《Teaching Education》2013,24(3):302-326

This study examined the mediating roles of prospective teachers’ boredom coping strategies (i.e. cognitive-approach, behavioral-approach, cognitive-avoidance, and behavioral-avoidance strategies) in the relationships between their perceptions of instrumentality and four aspects of engagement (i.e. agentic engagement, behavioral, engagement, emotional engagement, and cognitive engagement). A total of 521 prospective teachers participated voluntarily in the study. In addition to the latent factor and observed factor correlation analyses, a series of structural equation modeling analyses were conducted in order to examine the mediating roles of boredom coping strategies. The results demonstrated that perceived instrumentality, boredom coping strategies with the exception of cognitive-avoidance orientation, and four aspects of engagement were significantly related to each other. The results also showed that the relationships between perceived instrumentality and agentic engagement, behavioral engagement, emotional engagement, and cognitive engagement were slightly, but significantly mediated by cognitive-approach orientation. Implications for teacher education and directions for future studies were also discussed in the present study.  相似文献
