教学条件下中学生物学概念形成的实验研究

本实验借助假设检验模型对学生在习得条件下生物学概念形成过程进行探究,实验结果表明:1、学生生物学概念的形成存在高起点、缓增长、平台振荡的特点,没有突破现象;2、探究教学更有利于概念的形成.尤其利于发掘学生后程的学习潜力;3、学生对概念的掌握可能存在一个统计学意义上的阈值,相同条件下探究教学比讲授法较更利于学生达到该阈值.     

合法性原则与执政的选择——中共执政合法性资源积累之考察

人类社会的合法性执政有一定的原则规定性,中国社会执政合法性主要依赖于四个原则的检验:历史使命原则、治理效度原则、社会理想原则、治理方式原则。中国共产党执政合法性的现实,其实是在以上四个原则要求下不断积累执政合法性资源的一种外在表现,也可以说中共的具体执政是基于合法性原则的要求所作出的选择。通过对中共合法性资源积累过程的考察,我们不仅可以得出其现实执政合法性的原因所在,也可以得出其将来继续谋求有效执政地位的历史趋势,这两者统一于合法性原则所蕴涵的内在要求。     

忠的观念与近代中国民族主义

民族主义是与现代性相连,并与现代工业社会的发展有关,是现代性建构过程中的特殊产物.形成于近代的中国民族主义,既非一种历史的简单延续,也非政治意识形态的再现,而是社会公众在既定的历史条件下的一种自发性的情感认同.这一情感认同的对象,便是中国传统的思想文化,或许应该说是"忠"伦理的长期影响,所以中国民族主义从形成始便有其自身的特色.本文正是意图从"忠"伦理原本意义着手,考察"忠"伦理的演变过程,寻找出中国近代产生的民族主义特色的根源所在.     

不同程度尿蛋白患者血清甲状腺激素水平变化及其临床意义

探讨不同程度蛋白尿患者血清甲状腺激素水平的变化及其临床意义.66例不同程度蛋白尿患者,肾病综合征组28例,非肾病综合征组38例,健康对照组60例.发现蛋白尿水平与甲状腺激素水平尤其是FT3水平关系密切.在肾病综合征患者,主要表现为FT3显著降低,提示肾病综合征是正常甲状腺病态综合征的一种.     

Culture and Testing Practices: Is the World Flat?

There has been much speculation regarding the influence of cultural norms on the acceptance and use of personnel selection testing. This study examined the cross‐level direct effects of four societal cultural variables (performance orientation, future orientation, uncertainty avoidance, and tightness–looseness) on selection practices of organisations in 23 countries. A total of 1,153 HR professionals responded to a survey regarding testing practices in hiring contexts. Overall, little evidence of a connection between cultural practices and selection practices emerged. Implications of these findings for personnel selection and cross‐cultural research as well as directions for future work in this area are described.     

Educated and Happy: A Four-Year Study Explaining the Links Between Education,Job Fit,and Life Satisfaction

Drawing on a bottom-up theoretical perspective on life satisfaction, we developed and tested a model that specifies distinct paths from education to life satisfaction through three domain satisfactions (i.e., job, financial, and health satisfactions). Furthermore, we proposed explanatory mechanisms for each of these three paths (i.e., job fit, financial literacy, and proactive healthy behaviours). To test our hypotheses, we used a large probability sample comprising 3,011–9,669 individuals, from the Netherlands, who provided survey responses over four consecutive years. The results supported the hypothesised mediating mechanisms explaining the indirect relationship between education and job, financial, and health satisfactions. Findings also showed that each of these domain satisfactions independently predicts general life satisfaction. Overall, the study shows the importance of education for life satisfaction and highlights the importance of work (i.e., job fit and job satisfaction) for individuals' general subjective well-being.
