大学教师的专业发展影响学校的核心竞争力,也影响着培养学生的整体素质。目前比较有效的专业发展是大学教师的专业团队建设。如果能把团队建设和教师专业发展有效结合,不但会促进青年教师的快速成长,也会对学校的未来规划发展起到至关重要的作用。随着团队建设如火如荼的开展,对建设的成果考核是不容忽视的课题,需要考虑在考核时纳入专业发展的绩效考核体系。文章以关键绩效指标为依据,考虑从未来教师专业发展视角来分析团队建设的优势和不足,为后续政策制定、建设规划提供支持。研究结果设计了能够促进教师专业发展的对团队评估的关键绩效考核指标。 相似文献

2005年中国首次发布《中国的和平发展道路》白皮书,2011年9月6日中国再次发布《中国的和平发展》白皮书,向全世界公布中国和平发展的战略。中国采取什么样的发展战略,不仅对全球世界政治经济格局具有重要影响,同时也对全球应对气候变化的行动产生重要影响。重点分析了中国和平发展战略对全球应对气候变化行动的影响:(1)中国的和平发展,坚持以科学发展为指导,本身就是全球应对气候变化行动的重要组成部分;(2)中国的和平发展,推动了世界的和平与发展,有利于创造全球应对气候变化的良好政治经济环境;(3)中国的和平发展,推动了全球资源合理有效配置,有利于提高全球应对气候变化的实际成效;(4)中国的和平发展,提倡的是国际合作,有利于推动全球应对气候变化的国际协同。 相似文献

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying. 相似文献

The aim of this paper is to offer an alternative to a priori theorising in research on firm-level growth and environmental sustainability. We outline an approach that combines John Shotter's phenomenology with post-hoc application of the Bourdieusian concepts of habitus, practices and social capital. This is illustrated empirically through a study conducted with a small group of Finnish entrepreneurs, which examines their lived experience of growth alongside its practical application in their ventures. The entrepreneurs' responses reveal holistic perspectives on growth that extend beyond the economic to incorporate personal commitments to norms of collectivity and well-being for themselves and others. The paper offers an exploratory but empirically grounded approach, arguing that a combination of insiders' perspectives and attention to the social embedding of economic activity challenge the dichotomous distinctions between sustainable and conventional entrepreneurship and reveal a degree of commonality that would not be evident via conventional categorisations on the basis of features such as business model type. 相似文献

我国农民工的工资市场决定存在失灵,主要是农民工劳动力供求的变动对其工资水平的影响微弱,农民工劳动力短缺与其工资水平偏低并存。这种失灵直接源于农民工劳动力的供需矛盾性、需求垄断性和信息非对称性所决定的农民工劳动力市场的发育缺陷,根源于农民工劳动力市场所面临的包括以户籍制度为主的制度壁垒、重城轻乡的制度安排和信息传导的制度缺失在内的制度困境。而培育农民工劳动力市场、完善相关制度是解决其工资市场决定失灵的现实出路,其中转变政府职能是关键。 相似文献

This paper examines the aggregation of preferences with a finitely additive measure space of agents. We consider three types of non-dictatorship axioms: non-dictatorship, coalitional non-dictatorship, and atomic non-dictatorship. First, we show that the existence of an atom is a necessary and sufficient condition for the existence of a social welfare function that satisfies weak Pareto, independence of irrelevant alternatives, and coalitional non-dictatorship. Second, we simultaneously impose non-dictatorship and coalitional non-dictatorship, and specify a necessary and sufficient condition for the finitely additive measure that guarantees the compatibility among the axioms. Third, we impose all non-dictatorship axioms and show that the corresponding measure is extremely restricted. 相似文献

AbstractGender diversity is generally recognized as relevant in microfinance, and the relationship between gender diversity and firms’ performance has received attention in academic literature. The above-mentioned relationship has not been addressed until now in the microfinance industry specifically. This study seeks to explain the role played by gender diversity in the workforce of microfinance institutions (MFIs) during turbulent periods in the firms’ performance. The study analyses data from 555 ratings of 185 MFIs from MicroFinanza Rating, a leading microfinance rating agency. The analysis shows that the number of women on the staff of MFIs is significantly and positively associated with both the Return on Equity and Operational Self-Sufficiency of MFIs, indicating a positive impact of gender diversity on firms’ performance. 相似文献
