论扩张解释与类推适用的区分——以对我国刑法解释论之争的反思为切入点     

戴民杰 《湖南师范大学社会科学学报》2022,51(1):113-121

我国形式解释论与实质解释论之争的真正焦点在于刑法解释界限的宽严问题,而这主要体现在扩张解释与类推适用的区分问题中。根据概念的内在结构,扩张解释与类推适用的根本区别在于,扩张解释的涵摄对象是解释对象的中立选项,类推适用的涵摄对象是解释对象的否定选项。区分扩张解释与类推适用应遵循三个步骤：首先,明确解释对象与涵摄对象;其次,分析解释对象所具备的现实功能要素;最后,判断涵摄对象是否具备解释对象的现实功能要素。概念的现实功能要素是概念的内在规定性,是判断国民预测可能性的客观指标。当涵摄对象具备解释对象的现实功能要素时,其为解释对象的中立选项,该解释为扩张解释;反之,则为类推适用。即便某解释属于扩张解释,仍须接受规范目的的检验,不能将不应予以采纳的扩张解释错误地当作类推适用。  相似文献   

略论博物馆的“经常性观众”——基于三家博物馆的实证研究          下载免费PDF全文

近年来,欧美博物馆观众人数普遍出现不同程度的下降,如何留住核心观众成为西方博物馆界的当务之急。而我国博物馆在高速发展的过程中,也凸显出观众结构问题的隐忧。“经常性观众”成为探讨这些问题的重要基础性概念。为此,我们在界定“经常性观众”概念和爬梳其研究传承的基础上,针对南京博物院、成都金沙遗址博物馆和钱学森图书馆的来馆观众开展定量研究,围绕经常性观众的构成情况、影响变量以及变量与经常性观众的关系进行频次和交叉分析。研究发现当前我国博物馆绝大多数观众是非经常性观众,据此提出针对经常性和非经常性观众的不同策略;主张从内外两方面入手,将非经常性观众变成经常性观众,并以此作为长期目标,促使参观博物馆渐成日常。否则一旦“博物馆热潮”消退,将会不断失去观众,从而对博物馆的未来发展造成灾难性打击。  相似文献   

Secondary Students’ Stable and Unstable Optics Conceptions Using Contextualized Questions     

Hye-Eun Chu  David F. Treagust 《Journal of Science Education and Technology》2014,23(2):238-251

This study focuses on elucidating and explaining reasons for the stability of and interrelationships between students’ conceptions about Light Propagation and Visibility of Objects using contextualized questions across 3 years of secondary schooling from Years 7 to 9. In a large-scale quantitative study involving 1,233 Korean students and 1,149 Singaporean students, data were analyzed from responses to the Light Propagation Diagnostic Instrument consisting of four pairs of items, each of which evaluated the same concept in two different problem situations. Findings show that only about 10–45 % of students could apply their conceptions of basic optics in contextualized problem situations giving rise to both stable and unstable alternative conceptions. Students’ understanding of Light Propagation concepts compared with Visibility of Objects concepts was more stable in different problem situations. The concepts of Light Propagation and Visibility of Objects were only moderately correlated. School grade was not a strong predictive variable, but students’ school achievement correlated strongly with their conceptual understanding in optics. The teaching and learning approach and education systems in the two countries may have had some influence on students’ conceptual understanding.  相似文献   

Academic social bookmarking: An empirical analysis of Connotea users     

Helen S. Du  Samuel K.W. Chu  Gary E. Gorman  Felix L.C. Siu 《Library & information science research》2014

Three groups of social bookmarking users, namely experienced users, users with moderate level of experience, and novice users, were investigated, in terms of their reported tagging behaviors, perceived usefulness of social bookmarking in information discovery and management, and perceived usefulness of the bookmarking features provided. Based on the empirical analysis of the Connotea users, who are primarily in academia, the study shows that experienced academic users generally prefer to use social bookmarking while moderately experienced and novice users still prefer to use the traditional bookmarking methods, such as creating and using bookmarks on a dedicated computer. Experienced academic users were also found to create more tags per bookmark comparing to the other two groups. Most novice academic users, however, only created one tag per bookmark, which just met Connotea's minimum requirement. Surprisingly different from the collaborative design nature of the social bookmarking systems, the study finds that our participants, particularly experienced academic users, prefer to create and use their own bookmarks rather than sharing bookmarks created by others. In fact, experienced users have significantly higher frequency (once every two weeks) of creating bookmarks than the other two groups (once a month or less). In addition, website design features and functions, such as automatic collection of bibliographic information, are regarded by all participants as helpful for information discovery. The in-depth examination and discussion of the opinions of Connotea users may be useful for further improvement of the design features and usage applications, particularly for academic social bookmarking websites. The results may also have potential implications to the future development of social bookmarking services in general.  相似文献

从1992～1993年我国心理学研究动态看我国运动心理学研究的现状与发展     

褚跃德  张力为 《西安体育学院学报》1994,(2)

以《心理学报》、《心理科学》和《体育科学》三种权威性学术刊物１９９２年和１９９３年发表的论文为基础，对我国心理学和运动心理学的研究进行了分析，并探讨了运动心理学的发展方向，指出，中国运动心理学致力于为教练员、运动员的训练竞赛的决实际问题．其大方向适应了社会的要求，且硕果累累．当前运动心理学研究存在的问题是：选材研究的指导意义不强，研究课题的理论指导性差，心理测试仪器的研制落后于运动心理学实践的需要，研究方法尚未充分体现出心理科学研究的时代特征．建议应加强研究信息的搜集和整理，避免无意义的重复研究；加强理论研究，提高应用水平；提高研究人员自身的理论素质；加强多学科的协作．提高研究方法的水平；增加实验研究，建立运动心理学的理论体系．  相似文献
