谈档案工作"统一领导"与"分级管理"的合理结合   总被引:6,自引:0,他引:6  
1987年,我国《档案法》明确规定:“档案工作实行统一领导,分级管理的原则”。距今已经十几年了,但在认识上和实践中,仍有不少人简单地将该原则等同于“集中统一管理”原则,片面强调“统一领导,分级管理”的核心和实质就是“集中统一管理”,似乎“集中统一”的程度越高,便显得越正确,越是坚持了原则。这种认识上的误区,直接导致了档案行政管理中统得过死,管得过多,片面性,一刀切,过度强调整齐划一,经常忽视因地制宜等诸多弊端。因此,在档案工作中,  相似文献

We have studied the efficiency of research in the EU by a percentile-based citation approach that analyzes the distribution of country papers among the world papers. Going up in the citation scale, the frequency of papers from efficient countries increases while the frequency from inefficient countries decreases. In the percentile-based approach, this trend, which is uniform at any citation level, is measured by the ep index that equals the Ptop 1%/Ptop 10% ratio. By using the ep index we demonstrate that EU research on fast-evolving technological topics is less efficient than the world average and that the EU is far from being able to compete with the most advanced countries. The ep index also shows that the USA is well ahead of the EU in both fast- and slow-evolving technologies, which suggests that the advantage of the USA over the EU in innovation is due to low research efficiency in the EU. In accord with some previous studies, our results show that the European Commission’s ongoing claims about the excellence of EU research are based on a wrong diagnosis. The EU must focus its research policy on the improvement of its inefficient research. Otherwise, the future of Europeans is at risk.  相似文献

This study explored the co-developmental trajectories of autonomy, competence and relatedness need satisfactions at school and their relations to mental health and academic functioning in Chinese elementary school students. An accelerated longitudinal design was used with a sample of three cohorts (grade 3, grade 4, and grade 5) (N = 1070, 45.8% female; Mage = 9.44, SD = 0.97) on four occasions at 6-month intervals. Parallel process latent class growth models revealed five heterogeneous patterns (i.e., Congruent-moderate; Congruent-high; Congruent-low; Congruent-decreasing; Low-autonomy, High-competence and relatedness), all of which significantly associated with time-varying mental health and academic functioning indicators. The findings highlight the importance of subgroup differences and possible cultural considerations in understanding the progression of psychological need satisfactions and the need for universal screening and dynamic monitoring of students’ psychological need satisfactions at school and implementing more sophisticated interventions tailored to the unique characteristics of the relevant subgroups to promote optimal mental health and learning.  相似文献

The promotion of students’ achievement and competence in the so-called STEM disciplines is one cornerstone of current educational research and practice. In particular, as early as elementary school, the fostering of an adequate understanding of science is a normative goal of science education. It facilitates students’ science learning and enables them to understand the nature and development of scientific knowledge. Based on the relevance of the promotion of young children’s understanding of science, a corresponding science intervention was recently developed and successfully evaluated in a first study under highly controlled conditions. The goal of the present study was to investigate the effectiveness of this intervention when implemented in practice. One hundred seventeen third- and fourth-grade students and 10 trained course instructors participated in this study. We applied a randomized block design with waitlist control groups and repeated measures. The results revealed that children assigned to the intervention compared with children assigned to the waitlist control group showed better inquiry-related methodological competencies (a better understanding of the scientific inquiry cycle and experimentation strategies) and a higher need for cognition. The findings point to the successful implementation of the intervention and are compared with the results of the first study.  相似文献

近年来,未成年人刑事犯罪案件时有发生,针对是否降低未成年人刑事责任年龄问题,一直是学界讨论的热点话题。针对这一问题,学界形成的学说主要有降低论、不变论和弹性论,但各个理论都有自己的侧重点,如降低论学说侧重于扩大刑罚的打击范围;不变论则侧重于犯罪的社会预防;弹性论侧重于赋予法官的裁量权去防范该类犯罪。但从刑法的正当性依据、社会责任及我国法律体系一致性的需要角度来看,目前我国仍应保持当前刑事责任年龄不变。  相似文献
