公共图书馆馆员胜任力模型构建研究   总被引:4,自引:0,他引:4  
[目的/意义] 构建公共图书馆馆员胜任力模型,对于公共图书馆馆员的招聘、培训、考核及职业发展具有重要意义。[方法/过程] 采用文献分析法、开放式问卷法和专家访谈法收集胜任特征指标并编制频次及行为表现表,在此基础上设计结构化调查问卷,以SPSS 13.0为数据分析工具,通过实证研究和统计分析方法,研究公共图书馆馆员胜任力特征的构成,构建公共图书馆馆员胜任力模型,并在此基础上进一步分析影响模型各维度胜任特征的因素。[结果/结论] 研究表明:公共图书馆馆员胜任力模型由基本知识和业务能力、相关学科知识、计算机运用能力、职业态度和服务精神、情绪适应能力、组织沟通能力6个维度组成,职业态度和服务精神对工作绩效有显著影响。  相似文献

In science education, representations are necessary inter alia for the understanding of relationships between structures and systems. However, several studies have identified difficulties of students when working with representations. In the present study, we investigated students' responses (regarding their preference, test performance, mental load (ML), and stress) toward two kinds of representations: symbolic representations, which only use abstract symbols, versus combined symbolic–textual representations, which additionally comprise textual elements. Therefore, students were randomly assigned to one of two treatment groups: one group worked on test tasks accompanied by symbolic representations, and the others worked on the same tasks, but with symbolic–textual representations. Thereafter, the students' test performance and ML were assessed. The level of perceived stress and the salivary cortisol concentration were measured before and after the test and again a few minutes later. Additionally, heart rate variability parameters were assessed continuously. We found a strong preference of the test version with symbolic representations. Additionally, the students showed better test performance and lower ML when they worked with symbolic representations. However, the level of perceived stress was comparable between both groups and there was no strong physiological stress response: The cortisol concentration decreased in both groups and the heart rate was relatively similar. However, during the second half of the test, we observed a significantly higher ratio between low and high heartbeat frequencies in the group with symbolic–textual representations and we found an indirect influence of the kind of representation on test performance through its effect on ML. The poorer test performance and higher ML in connection with symbolic–textual representations confirm previous studies, which found that symbolic–textual representations pose major problems for students. Thus, teachers should enable students to understand symbolic–textual representations and consider carefully whether they can use symbolic representations instead, especially when they teach complex content.  相似文献

Abstract

Russia’s (and the USSR’s) use of sports mega-events (SMEs) makes this BRICS country (Brazil, Russia, India, China, and South Africa) not only an outlier among emerging states, but also among key SME hosts generally. Both the historic Moscow Olympics (1980) and the more recent hosting of the 2014 Sochi Winter Olympics provide evidence that Russia has, on both occasions, focussed on geopolitical priorities using hard power (military might) at the expense of soft power acquisition. Furthermore, both Olympics were, first and foremost, used to pursue domestic soft power goals. This, again, makes Russia an outlier in terms of the political use of SMEs by states in the literature on this subject. The 1980 Olympic Games, therefore, in terms of their potential to generate soft power and national unity, turned out to be a mis-used opportunity for Russia. To what extent is this specific to Russia and could the first Russian Olympics provide valuable insight into the modern-day hosting of SMEs by Russia (2014/2018)?  相似文献

Abstract

In this paper, we highlight the need to explore the excessive significance given to the Paralympic Games as a vehicle for the encouragement of participation of people with a disability within sport. The media spectacle around the games that the International Paralympic Committee (IPC) has worked tirelessly to develop has become, for policy-makers and the public alike, a sufficient outlet for disability sport provision. The honourable goals of the IPC articulated through the ethos of Paralympism have been assumed to be valid for all people with a disability, yet in terms of widening participation, their utility is limited. This paper first illuminates the relationship between the International Olympic Committee and the IPC before we turn our attention to the ethos of Paralympism. Highlighting the necessity for ‘sport for all’, we use a human rights lens, aided by a capabilities approach to facilitate better ways to educate the public about the need for equality of access to sporting participation opportunities.  相似文献
