从钱伟长“教学改革思想”看“全面发展”的MBA教育教学改革与创新

MBA教育具有重要的社会使命,也是社会企业模式的一种.MBA教育是应用商业手段于学校这个非营利机构,以便有效地为社会持续培养符合社会需要的人才的教育服务.此外,东西方都在金融危机后重新思索企业到底需要什么样的人才,这些都决定了MBA教育必须进行改革和创新.钱伟长院士的"教学改革思想"为要培养能融合"企业经济利益、社会人文发展、自然环境保护"和"东西方管理"的跨学科与全面发展商业管理与领袖人才的MBA教育改革和创新提供了重要指导方向.在此基础上,本文提出建立"和而不同"的"东西融合"与"企业利益、社会人文发展与环境保护"的和谐发展"全人教育MBA教育模式",最后对整个研究进行了总结和进一步的展望.

A quantitative study of financing efficiency of low‐carbon companies: A three‐stage data envelopment analysis

This study set out to evaluate the financing efficiency of low‐carbon companies. Applying a three‐stage data envelopment analysis with the data from 85 listed companies in China's low‐carbon industries over the period 2011 to 2017, this study has found that the overall financing efficiency of low‐carbon companies was relatively high, and the pure technical efficiency was quite steady over the period. The overall financing efficiency of these low‐carbon companies on average tended to change with the scale efficiency. This study has also shown that the scale efficiency was the main constraint influencing the financing efficiency of low‐carbon companies in China over the period. Our results are robust and have significant implications for policy makers and corporate managers.     

Donor recognition: A double-edged sword in charitable giving

Previous studies discover confounding results on how donor recognition affects individual charitable giving. To answer the questions of how different donor recognition schemes affect individual giving and what type is more effective as a marketing strategy to meet different fundraising goals, we conducted a field experiment in China with three donor recognition types: voluntary, involuntary, and mandatory donor recognition. We used social media to recognize donors and verified the field experiment results with naturally occurring data. We observed similar behavioral patterns in both samples. The results of this study explain the mixed results from previous studies, suggesting that there is no one-size-fits-all approach for recognizing donors. Decision makers of nonprofit organizations need to select the appropriate type of donor recognition based on their fundraising goals.     

高校科普研究进展

高校为高等院校的简称。高校科普就是指高等院校的组织、机构和个人利用高校的设施、设备和人员开展的科普活动与行为。通过检索新世纪以来我国高校开展科普研究的文献,发现我国高校科普研究多集中于实践层面,理论研究较为少见。实践研究多是从高校科协工作、高校博物馆（档案馆、标本馆和图书馆）开放、高校科普教育基地建设工作和面向高校师生开展科普工作、高校科普创作的重要意义、实施策略（方式）以及机制等内容。高校科普基础理论研究的文章较少,主要体现在高校科协建设理论、高校科普内涵、科研科普的关系等内容。综合来看,高校科普研究内容较多,但是深入不够;实践研究多,理论研究少;实践研究多集中于方式方法研究,而机制和途经研究少;从发展的角度看,高校培养科普人才、高校科普志愿者研究、高校科普创作研究和高校科研科普关系研究将会成为未来的研究热点。

流动性过剩与股票价格重估

在固定汇率与资本管制框架下,剩余储蓄的持续增加必然导致流动性过剩,对股票市场而言,只有当实体经济持续的剩余储蓄增加引起流动性过剩时,才会推动股票市场估值中枢的剧烈抬升.对近期经济指标的分析表明,股票市场重估将会持续下去,而货币政策紧缩引起的投资下降会进一步扩大剩余储蓄,加快重估的进程.     

网络技术在施工管理中的应用问题

网络计划方法自20世纪60年代传入中国后,在生产中得到了应用,它符合工程施工的要求,特别适用于施工的组织与管理。同国外发达国家相比,目前我国在网络计划技术的理论水平与应用方面相差无几,但在应用管理上,特别是计划执行中的监督与控制以及跟踪调整方面比较落后,基本上停留在计划的编制上。如何在施工管理中提高网络计划技术的应用水平是本文所要讨论的问题。
