Acute starvation in C57BL/6J mice increases myocardial UCP2 and UCP3 protein expression levels and decreases mitochondrial bio-energetic function

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.     

论犹太教对外邦人改宗的矛盾态度

犹太教是一个民族性的宗教。对改宗犹太教的外邦人,拉比们一方面给予他们积极的评价,另一方面又对他们表现出怀疑排斥的消极态度。从根本上说,这种矛盾态度是由犹太教对自身的不同理解造成的。一方面,犹太人将自身看成由律法塑造的宗教共同体;另一方面,犹太教又始终将自身理解为一个民族,甚至其改宗程序,也是为了在象征意义上建立改宗者与犹太人的血缘关系。犹太教对其民族性的坚持是她无法向外邦人敞开怀抱的主要原因。     

Free Time Management Contributes to Better Quality of Life: A Study of Undergraduate Students in Taiwan

This study was designed to identify the relationship between free time management and quality of life, exploring whether the amount of free time or the way people using their free time relates to their quality of life. Data were collected from National Pingtung University of Science and Technology in Taiwan. Of the 500 questionnaires distribute, 403 usable questionnaires were received with an 81% response rate. The result has found a positive relationship between free time management and quality of life. Contrary to this, there was no significant relationship between time allocation and quality of life. Results might indicate that people who manage their free time well lead to better quality of life. Suggestions based on the observed relationship and directions for future researches were discussed.     

真实自豪与自大自豪倾向量表的修订及适用

对Tracy和Robins编制的真实自豪与自大自豪倾向量表进行中文版修订并初步考察我国大学生自豪感的特点,分别选取202名和484名大学生进行问卷预测和正式施测。验证性因素分析表明修订后量表仍保持英文版的双维结构,两分量表的α系数为0.785和0.743,重测信度为0.978和0.952。修订后量表具有良好的心理测量学指标,可以用于我国大学生的测试。进一步发现我国大学生的真实自豪显著高于自大自豪,大学生自豪感不存在性别差异,自大自豪存在显著的年级差异。     

震后一年半灾区小学生的创伤症状调查研究——以“八一帐篷学校”为例

本研究对总装备部·绵阳八一帐篷学校的小学生进行创伤症状调查研究,了解震后一年半小学生的心理健康状况。方法:使用儿童创伤症状量表简版(TSCC-A)对八一帐篷学校3～6年级小学生进行评估。结果:(1)八一帐篷学校的小学生震后一年半最为突出的创伤症状是焦虑,其次为抑郁和分离症状;(2)在创伤症状得分上不存在性别差异性,但是存在年级差异性,三年级学生创伤症状得分均低于其他年级学生;(3)震后一年半学生创伤症状比震后半年学生创伤症状有所减轻。结论:灾区小学生心理健康状况仍存在一些问题,焦虑、抑郁等症状仍比较明显,还应进行持续的心理危机干预。

外国留学生对汉语句子中补语认知的实验研究

采用语言实验方法,探索外国留学生的母语和汉语输入在习得中作用问题。选择了母语为英语、日语和韩语,汉语水平为初等的留学生为被试。研究发现,母语在习得汉语的前期有重要作用。母语相关语言规则与汉语补语差别最大的留学生,他们对汉语补语不同水平间差别反应的敏感性最高;差别最小的,敏感性最低;介于其间,则敏感性为中等。此外,汉语输入对习得也有作用,其难易影响习得的效果。     

角色方式对心理旋转的影响

人类视觉系统通常以第一人称角色和第三人称角色形式建构客体的空间表征,也运用这两种角色方式进行空间表征的动力转换。本研究采用实验方法,对这两种角色方式的心理旋转进行对比性研究。结果发现:空间表征转换的角色方式对心理旋转产生显著影响,第三人称角色心理旋转易于第一人称角色心理旋转,即存在心理旋转的角色效应。     

中国文化中内隐自大对人际吸引力的影响

研究考察了中国被试的内隐自大是否能够被激发从而影响人际吸引力。通过两个实验,研究者发现,在中国被试当中内隐自大不但会被被试自己的姓所激发,也能被被试母亲的姓所激发;被试会偏好那些和自己或者自己母亲的姓相似的对方,而这种偏好在遭遇自我概念威胁之后更加明显,而在受到自我肯定之后会受到抑制;对母亲概念的威胁和对自我概念的威胁作用基本类似。另外,母亲的姓比起被试自己的姓来,激发了被试更大更一致的受吸引程度。这说明母亲概念属于自我概念当中比较积极正面的一部分。
