电击信号应激对大鼠体液免疫及内分泌功能的影响 总被引:19,自引:1,他引:18
研究了足电击及以电击装置为信号刺激所诱发的情绪应激对大鼠原发性体液免疫反应及内分泌的影响。 结果表明每天10分钟,共6天的足电击对大鼠抗特异性抗原OVA的原发性体液免疫反应无明显作用,而此电击作 用结合每天10分钟,共8天的情绪应激则可显著降低大鼠体液免疫反应及脾脏指数。同时该应激可显著提高大鼠 血儿茶酚胶和皮质酮水平。该研究证明了情绪应激对大鼠体液免疫功能的调节作用,并对交感神经系统和下丘脑- 垂体-肾上腺(HPA)轴在其中所起的作用进行了初步探讨。 相似文献

本文在春秋时期齐国齐桓公和管仲的经济政治改革中相伴产生了“四民分业”的社会职业教育思想,这是据现有文献记载的中国最早的比较全面系统而深刻的社会职业教育思想,有很强的时代和自身的特色,对后世的职业教育产生了深远的影响。从中可以看出当时先进国家中,教育是如何为富国强兵的政策服务的。 相似文献

中国古代关于认识真理性检验标准的思想可以大致归纳为四种主要观点。先秦及汉代的唯物主义思想家已经有了把感觉经验和行为效果作为检验认识真理性标准的思想;古代唯心主义思想家则坚持无客观标准论,他们要么直接坚持主观标准论,要么认为根本无是非标准可言;宋、明、清时期的一些唯物主义哲学家提出并坚持以客观事物或事实作为检验认识真理性的标准;与此不同,王廷相、王夫之、颜元等人则提出“行”标准说,这种颇具光辉的哲学思想,使中国古代关于认识真理性检验标准思想的探讨大大前进了一步。 相似文献

春秋战国时期是第一个大变局时期。在政治格局上,亲缘政治开始瓦解而地缘政治开始兴起。诸侯国兴起,春秋的历史基本上都是围绕着“争霸”这个主题展开的:制度改革、学术争鸣以及兼并战争。齐法家在春秋时期通过一系列主张帮助齐国在争霸中强大起来。笔者认为,其主张中已经包含接近现代国际法的国际法理念。齐法家思想中的国际法要素主要体现在齐国主持的历次会盟的盟约,以及齐法家的代表人物的外交活动中所遵循的原则中,本文着重从这两个方面展开论述。 相似文献

道家学派理论面对忧患强调“天人合一”和解脱,因而具有浓郁的审美意识倾向。道家学派对“道”的体认也体现在对音乐本质的理解上。审美主体伴随着质态不尽相同的音乐过程,依次连缀形成“有声之乐”、“无怠之声”和“天乐”这三个层面的心理过程流时,这样的音乐才是老子所谓的“大音”,才是道家学派理想中的音乐。 相似文献

Self-esteem affects individuals in a variety of psychological processes substantially and extensively. While an increase in self-esteem over time was observed in the USA, different patterns of temporal change in self-esteem were observed in other societies. We analysed the responses (n = 305 229) collected between 1993 and 2016 from 609 articles to examine the patterns of temporal change in self-esteem in China and its relations with socioecological conditions. Additionally, we explored the patterns in different groups, including secondary school students (158 samples; n = 97 751), college students (427 samples; n = 153 474), and community participants (232 samples; n = 54 004). Some major findings were noted: (i) overall, the level of self-esteem increased over time. However, we also found a significant curvilinear trend in self-esteem with a decline followed by a recent increase; (ii) some evidence for the relationship between socioecological factors and self-esteem was obtained; and (iii) the patterns varied in different cohort groups. Specifically, secondary school students showed a different pattern, in which their self-esteem level did not show a significant linear trend and was not correlated with the examined socioecological factors. The implications on the theories for the relationship between personality characteristics and socioecological conditions were discussed. 相似文献

This 1-year longitudinal study examined relations between maternal power-assertive parenting and children's social, academic and psychological adjustment in China. Participants were 316 elementary school children (mean age = 11 years, 153 boys). Maternal power-assertive parenting was assessed using children's self-reports. Data on children's social and school adjustment were obtained from peer evaluations and teacher ratings. In addition, children completed measures of loneliness and depression. Cross-lagged analyses indicated that whereas maternal power-assertive parenting was only related to later academic adjustment, children's adjustment in socioemotional and academic domains contributed to the prediction of later maternal power-assertive parenting. The results were discussed in the Chinese context. 相似文献

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed. 相似文献
