选择从农村流入到北京打工的18-30岁的年轻流动人口共2201人参加问卷调查,要求被试自我报告他们的饮酒行为、流动时间、流动城市数量以及抑郁和满意度状况,并根据他们所从事的13种职业的性质将之归类为“低危”和“高危”两类,以考察环境和个体因素与流动人口饮酒行为的关系。结果表明:(1)在过去1个月中,27%的流动人口曾醉过酒,男性流动人口的醉酒率是女性的2倍(35%vs.16%)。但流动人口的饮酒行为不存在显著的年龄、教育水平和婚姻状况的差异;(2)相关分析表明,高危职业流动人口的饮酒行为显著地高于低危职业的流动人口。同时,与没有醉过酒的流动人口相比,曾醉酒者的抑郁情绪更多,生活和工作满意度更低;(3)Amos结果表明,环境和个体因素相互作用影响流动人口的饮酒行为。流动性通过满意度以及抑郁情绪间接地影响流动人口的饮酒行为,职业性质对饮酒行为产生直接的影响,同时,职业性质又通过生活满意度和抑郁情绪间接地作用于流动人口的饮酒行为。 相似文献

成就目标的一种新分类——四分法 总被引:14,自引:0,他引:14
在成就目标二分法和三分法的基础上,依据能力划分的两个维度-能力的界定维度和效价维度,Pintrich和 Elliott等人提出了成就目标的四分法,将成就目标分成掌握-接近目标,关注于掌握新的知识和提高自己的能力;掌握-回避目标,关注于避免完不成任务或避免失去已有的知识技能;成绩-接近目标,关注于表现得比他人优秀和胜过他人和成绩-回避目标,关注于避免表现得比他人更差或更愚蠢4种类型。实证研究表明,四分法不仅完善了成就目标的分类研究,而且也为提高个体的成就水平提供了理论依据。 相似文献

理性主义是西方哲学两千多年发展的主导方面,非理性主义是其附属方面,双方构成西方哲学史中的一对矛盾,后者是在前者的基础上再加超越和提升的结果.这一矛盾来自古希腊理性的两大精神要素逻各斯和努斯的交替上升,体现为柏拉图的"迷狂说",但不是前理性的迷狂,而是理性基础上的迷狂,有别于中国传统的非理性.西方哲学的非理性是由理性中的努斯发展出来的,但常与宗教神秘主义合一,到黑格尔才明确将二者分开,但仍免不了堕入理性神学. 相似文献

Associations between uncoupling protein (UCP) expression and functional changes in myocardial mitochondrial bio-energetics have not been well studied during periods of starvation stress. Our aim was to study the effects of acute starvation, for 24 or 48 h, on combined cardiac mitochondrial function and UCP expression in mice. Isolated heart mitochondria from female mice starved for 48 h compared to that from mice fed revealed a significantly (p < 0.05) decreased adenosine diphosphate-to-oxygen ratio, a significantly increased proton leak and an increased GTP inhibition on palmitic acid-induced state 4 oxygen consumption (p < 0.05). These bio-energetic functional changes were associated with increases in mitochondrial UCP2 and UCP3 protein expression. In conclusion, our findings suggest that increased UCP2 and UCP3 levels may contribute to decreased myocardial mitochondrial bio-energetic function due to starvation. 相似文献

旨在编制青少年日常情绪调节问卷,通过增添对日常情绪诱发情境的描述,增强关于对青少年日常情绪调节测量的生态效度,获得更具有现实意义且真实的结果。根据访谈(n=30)获得诱发青少年日常情绪的典型情境,编制了问卷的项目;根据探索性因素分析(n=268)确定的正性情绪调节问卷项目为15个,负性情绪调节问卷项目为20个,皆抽取了四个因素分别命名为"认知重评"、"认知沉浸"、"表达抑制"、"表达宣泄"。经验证性因素分析(n=269)以及信度检验,问卷的各个心理测量学指标均符合要求,表明该结果具有良好的结构效度和内部一致性,可用作青少年日常情绪调节的测量工具。 相似文献

This study investigated gender differences in the relationship between creativity and academic achievement. A sample of 1082 primary students participated in this study in Beijing, China. Their age ranged between 8 and 15 years old (M = 10.41, SD = 0.99). Students’ creativity was measured by the Chinese version of the Torrance Test of Creative Thinking Figural Form A, and academic achievement was based on students’ self-reported grades of last semester. Results revealed that there was a significantly positive relationship between creativity and academic achievement, ranging from r = .07 to r = .21. Gender differences regarding which aspects of creativity were related to academic achievement were also found. Plausible explanations and implications of the findings in creativity research and education are discussed. 相似文献
