传统上,目录学是与校雠、版本等学科共同发展起来的,在治学术史和文化方面都发挥着重要作用。数字时代,目录学的生存环境发生了深刻变化。信息数量、类型、传输方式以及用户行为的变化对目录学提出了新的要求。本文在分析数字时代目录学学科环境特点的基础上,提出了目录学变革的四条路径:目录学学科化、书目工作职业化、发展通用技术以及建立现代目录学逻辑体系。 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

《仪礼.士冠礼》详细、系统地记载了冠礼正礼的仪节。但是,冠礼仪式在正礼之外,还有一些特殊情形,主要有:用醮、庶子冠礼、孤子冠礼、是否用乐、冠者母不在、将冠而遇丧事、天子诸侯加冠,等等,反映了当时的礼制具有一定的弹性和地域差异、身份差异,而不是整齐划一的。 相似文献

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010~2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组(P<0.05),骨密度显著低于对照组大学生(P<0.05),这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。 相似文献

Relative age effect (RAE) in sports has been well documented. Recent studies investigate the effect of birthplace in addition to the RAE. The first objective of this study was to show the magnitude of the RAE in two major professional sports in Japan, baseball and soccer. Second, we examined the birthplace effect and compared its magnitude with that of the RAE. The effect sizes were estimated using a Bayesian hierarchical Poisson model with the number of players as dependent variable. The RAEs were 9.0% and 7.7% per month for soccer and baseball, respectively. These estimates imply that children born in the first month of a school year have about three times greater chance of becoming a professional player than those born in the last month of the year. Over half of the difference in likelihoods of becoming a professional player between birthplaces was accounted for by weather conditions, with the likelihood decreasing by 1% per snow day. An effect of population size was not detected in the data. By investigating different samples, we demonstrated that using quarterly data leads to underestimation and that the age range of sampled athletes should be set carefully. 相似文献
