浅谈高校学生干部能力培养的二元性

高校学生工作是高校贯彻党的教育方针,培养＂德、智、体等全面发展的社会主义事业的建设者和接班人＂的关键环节,是学校整体育人工作的重要组成部分。高校学生干部是联系学校和学生、老师和学生的纽带,是学生工作的重要力量。对学生干部的培养,面临着管理能力和专业能力两方面的培养,即二元性。在培养和管理中处理好二者的关系,方能建设一支稳定而强干的学生干部队伍,充分发挥其先锋与桥梁作用。

从爱、信两难到时、空交融——论王国维中西传统美学现代转化方法论历程与思维模型

被称为"王国维难题"的"可爱者不可信,可信者不可爱"——是一个"二律背反"的命题,这个悖论的产生是西方现代哲学文化中理性与感性、科学与人文、形式与内容、外在与内在、时间与空间的二元对立、矛盾所致。王国维的伟大之处在于,他最早自觉发现了西方现代主义哲学的这种矛盾并中西求索以解决之,其成果便是时空交融、意与境浑、入内出外的境界论时空美学。其实,这个问题解决的过程与成果就是对中西传统文化、现代主义进行的现代转化,从而使他的美学超越了美在形式、美在社会实践的现代主义哲学与美学范式,而进入美在生命时空的美学与哲学前沿。     

When the former ceo stays on as board chair: effects on successor discretion,strategic change,and performance

Prior research on CEO succession has omitted consideration of a critical institutional reality: some exiting CEOs do not fully depart the scene but instead remain as board chairs. We posit that predecessor retention restricts a successor's discretion, thus dampening his or her ability to make strategic changes or deliver performance that deviates from pre‐succession levels. In short, a predecessor's continuing presence suppresses a new CEO's influence. Based on analysis of 181 successions in high technology firms, and with extensive controls (for circumstances associated with succession, the firm's need and capacity for change, and for endogeneity), we find substantial support for our hypotheses. In supplementary analyses, we find that retention has a more pronounced effect in preventing a new CEO from making big performance gains than in preventing big drops.

On the optimal portfolio for the exponential utility maximization: remarks to the six-author paper

This note contains ramifications of results of Delbaen et al. (2002). Assuming that the price process is locally bounded and admits an equivalent local martingale measure with finite entropy, we show, without further assumption, that in the case of exponential utility the optimal portfolio process is a martingale with respect to each local martingale measure with finite entropy. Moreover, the optimal value always can be attained on a sequence of uniformly bounded portfolios.     

跳单问题的研究范式与理论成果

以最高人民法院公布的首批首个指导性案例——“跳单案”为典型的跳单问题在各行各业广泛存在,其中蕴含丰富的经济学和法学内涵,更是产业组织理论和法律经济学的重要研究方向,可谓新发现的“学术金矿”。本文是相关研究成果的一个综述,主要包括：跳单问题的提出,分析框架——B T C范式,基本理论——跳单二重性理论、跳单与反跳单互克理论、跳单定理与定律以及基于跳单的租金结构新论,构成一个比较完整的理论分析体系。
