Adaptation of lesson study in a Danish context: Displacements of teachers’ work and power relations     

《Teaching and Teacher Education》2020

Though lesson study adaptations in the West have flourished, there is scarcity of associated culturally sensitive research. We contribute such research by exploring the conflicts that emerge when Danish teachers engage in lesson study. Using figured worlds, we analyze how teachers realize lesson study in their local setting through their dynamic orientations towards possibly conflicting worlds. We show how this realization challenges the teachers’ work and power relations and is influenced by broader issues of culture and power. We conclude that, in order to adapt lesson study in Denmark, it is necessary to address the overriding cultural characteristics we identify.  相似文献   

新兴交叉学科科技管理平台工作体系研究     

高崴  姚毓春 《科技管理研究》2021,41(4):104-108

论述新兴交叉学科及其科技管理平台和工作体系的内涵、特点及发展趋势,认为新兴交叉学科发展需要与其特点相适应的平台,平台建设也需要与其特点相适应的工作体系。研究发现,目前我国大学仅依托院系的单一组织形式面对新兴交叉学科发展,逐渐暴露出观念不足、体制机制不健全、科研自主权不充分、资源投入不持久、科研人员意愿不强、合作方式单一等诸多问题,问题的核心是没有构建与其相适应的科技管理工作体系。进一步从模式、理念、机制、人员4个角度入手,提出加强和优化高校新兴交叉学科科技管理平台建设发展路径,包括原有学院转型等4种模式、发展规划和生态目标制定、建立国际合作和联合攻关机制等5种工作机制以及联合聘任专家等4种人才管理方式。  相似文献   

Biculturalism as a double-edged sword: The perspectives of Mexican American emerging adults     

《Int J Intercult Relat》2023

Cultural and ethnic identity research largely highlights the adaptiveness of biculturalism among Latino youth in the United States. Less is known about how Latino youth themselves define and experience biculturalism, the cultural identity content that they deem relevant, and how heritage and host identities intersect. Using an inductive approach, this study examines the salience, valence, and meaning of biculturalism among Latino youth living in a multicultural U.S. city. Twenty-six Mexican American emerging adults (M_age = 22.35 years) participated in semi-structured interviews and constructed cultural identity maps focusing on their experiences of biculturalism. Qualitative analysis reveals that participants overwhelmingly deem biculturalism to be positive and explores the duality (i.e.: opposition or contrast) that lies beneath that positivity. Participants emphasized individual-level advantages of biculturalism, namely, that their Mexican heritage provides identity rootedness and enables expanded career and educational opportunities. The bicultural challenges that participants discussed were overwhelmingly relational: familial cultural gaps due to dissonant values and critical gazes from others due to inadequate cultural performances. By revealing that and why biculturalism is mostly positive in the eyes of participants, and exploring the duality that lies beneath that positivity, this study draws attention to the complexity of biculturalism that can be obscured by exclusive reliance on quantitative self-report measures.  相似文献

Factors influencing venture capital perforsmance in emerging technology: The case of China     

《国际创新研究学报(英文)》2023,7(1):18-31

This study aims to identify the systematic factors influencing venture capital performance in emerging technology. Emerging technologies are the driving force of contemporary economic and social development, but their technologies and markets are subject to great uncertainty. As a high-risk, high-yield investment method, venture capital plays an extremely important role in supporting technological innovation and promoting the upgrading of industrial structures. Following information processing theory, this study applies a quantitative analysis to data from 61 venture capitalists in Beijing, China using structural equation modeling (SEM). The sample firms were established since 2015 and invested mainly in emerging technology startups. The model passed the goodness-of-fit indices test and reveals that information acquisition, venture capital executives, and venture capital strategies have a positive impact on venture capital performance, and venture capital strategies played a partial mediating role.  相似文献
