电工学课程教学互动创新实践探索

针对电工学课程传统课堂教学效果欠佳、实验教学和工程实践联系不紧密以及教学考核方式单一等问题,在凝练电工学教学经验的基础上,从理论教学、实验教学、教学考核三个维度介绍了深度教学互动的实例,探索提高电工学授课效果的教学互动模式,在电工学的教学实践中取得了较好的教学效果。     

On the Relationship between Domestic Saving and the Current Account: Evidence and Theory for Developing Countries

We examine the relationship between domestic saving and the current account in developing countries. Our three main findings are that: (i) domestic saving has a small effect on the current account; (ii) domestic saving has a significant positive effect on the trade balance—this effect is much larger than the effect that domestic saving has on the current account; and (iii) domestic saving has a significant negative effect on net-current transfers. We use countries in the SSA region during the period 1980-2009 as a laboratory for an instrumental variables (IV) approach. The IV approach enables to obtain estimates of causal effects. Underlying the IV approach is the significant positive first-stage response of domestic saving to plausibly exogenous annual rainfall: an unanticipated, transitory supply-side shock. We construct a small open-economy DSGE model with debt adjustment costs and endogenous current transfers to match the empirical findings. The model enables to examine the relationship between domestic saving and the current account for different types of shocks. An important message of our paper is that, for developing countries, estimates of the relationship between domestic saving and domestic investment are not informative for answering the question how domestic saving affects a country's accumulation of net foreign assets.     

名义帐户制探析

名义帐户制度是近年来国际养老保险制度改革中出现的一种制度创新,它已引起了部分转型国家的极大兴趣和许多专家学者的关注.但作者认为,名义帐户制作为一种过渡安排,并不能解决养老保险制度的根本问题.中国仍应坚持社会统筹与个人帐户相结合的部分积累制的养老保险制度.当前,中国应继续完善试点,积级探索做实个人帐户的有效方式,着力解决个人帐户的隐性负债问题.     

论西方人权理论对当代大学生人生价值观的影响

西方人权理论是西方文化的重要内容，是积极与消极、进步与落后并存的人权理论，它对大学生人生价值观造成的负面影响日益凸显，要克服这一消极影响，需要高校多渠道、全方位地开展工作，增强大学生对西方人权理论的认知能力和免疫能力。     

An Empirical Test of the Impact of Managerial Self-Interest on Corporate Capital Structure

This paper provides a test of whether capital structure decisions are at least in part motivated by managerial self-interest. It is shown that the debt ratio is negatively related to management's shareholding, reflecting the greater nondiversifiable risk of debt to management than to public investors for maintaining a low debt ratio. Unless there is a nonmanagerial principal stockholder, no substantial increase of debt can be realized, which may suggest that the existence of large nonmanagerial stockholders might make the interests of managers and public investors coincide.     

Interindustry Wage Differentials and Unobserved Ability: Siblings Evidence from Five Countries

We examine the role of unobserved ability in explaining interindustry wage differentials. By using data on brothers, we account for unmeasured abilities shared by siblings. The data came from four Nordic countries and the United States. In the Nordic countries, only a moderate proportion of the variability in industry wages can be attributed to unobserved ability, while unmeasured factors explain as much as half of the U.S. industry‐wage variation. Accounting for such differences, we show that the U.S. interindustry wage dispersion is similar with that in the Nordic countries.     

城市交通战略、交通政策的表现形式——交通白皮书的编制研究

有时限取送混合车辆路径问题的模型及其禁忌搜索算法研究

研究了带时间窗的取送混合车辆路径问题.问题中,每个客户带有取货和送货两个时间窗,每个客户处的取货和送货任务可以通过访问一次全部完成,也可以分两次访问分别完成送货和取货任务.在对该类问题进行描述和取送一体化战略的基础上,建立了有时限取送混合车辆路径问题的数学模型.通过设计一种新的解的表示方法构造了该问题的禁忌搜索算法.实验计算结果表明,用该禁忌搜索算法求解有时限取送混合车辆路径问题,不仅可以取得很好的计算结果,而且收敛速度较快,计算结果也较稳定.     

论罗伯特·欧文的企业社会责任观

罗伯特·欧文不仅是著名的空想社会主义者，也是卓越的企业管理者，他在新拉纳克所进行的30年试验证明了自己是企业社会责任的先驱和典范。从欧文关于新拉纳克试验的论述可以提炼出他的企业社会责任观，主要涉及三个方面问题：目的、可行性以及局限性。从目的来看，欧文认为企业履行社会责任只能是在以获取利润为根本的前提下实现企业与相关利益者的共赢；从可行性来看，欧文认为企业主与雇佣劳动者的利益是一致的，照顾好雇佣劳动者不但不会损害企业主的利益，反而会扩展商品销路和提升管理效率；从局限性来看，欧文认为企业履行社会责任所能产生的效果必然要受到资本主义生产方式的制约。发掘欧文的企业社会责任观所得到的启示是，通过企业社会责任建设来应对我国当前企业与社会之间的矛盾是可行的选择，但也只是治标之策。
