房地产类课程教学中存在的问题及改革对策探索

目前,在房地产类课程教学中存在着课堂上采用传统式理论灌输教育模式、学生普遍缺乏实践动手能力和创新意识、教材内容的陈旧以及考核方式的单调等问题,导致绝大部分学生被动的接受课程理论知识,而走上工作岗位以后不能很好将理论应用于实践中,有鉴于此,本文对房产类课程教学中存在的问题进行了分析并给出一些可行的教学改革对策,为房地产类课程的教学提供借鉴。     

高校开放实验教学中实验教学示范中心的现状和发展——基于浙江省杭州市下沙高教区高校的研究

文章从下沙高教园区高校开放实验教学的实际情况出发,以实验教学示范中心为主要研究对象,通过问卷调查,网络调查与实地考察相结合的形式,介绍了实验教学示范中心体系,包括实验教学队伍,实验室制度以及实验室环境等组成要素。针对示范中心现有问题,提出改革措施,同时对中心体系作了总体规划,为现行高校实践教学改革提供理论参考。     

Do regions matter? An integrated institutional and semiglobalization perspective on the internationalization of MNEs

Traditional research suggests a relationship between country‐level institutions and the location choices of MNEs. However, more recent theory suggests MNEs also focus on regions (semiglobalization). Therefore, this study examines institutional effects in the context of semiglobalization by considering the influences of three formal institutions (i.e., regulatory control, political democracy, capital investments) of countries and geographic regions on MNEs' location choices of internationalization. We use a sample of Japanese MNEs operating in 45 countries within eight regions. The results show that their degree of internationalization into a country is influenced by both country and regional institutional environments. Additionally, a semiglobalization perspective provides better explanatory power than does the country‐level perspective. These results present a new perspective on how MNEs consider institutional environments in their international strategy. Copyright © 2013 John Wiley & Sons, Ltd.

论产业引导资金的绩效管理

产业引导资金是政府财政预算安排的一类专项资金。从经济性、效率性和效果性的三维角度对产业引导资金的使用绩效进行评价，对于加强财政管理，落实宏观调控，遏制公权腐败以及提升被扶持对象的管理水平有着重要的、积极的意义。当前产业引导资金在资金投向、制度设计、审核操作、项目实施等方面存在的一些问题不同程度地制约了资金绩效的发挥，亟待改进。     

浅谈混凝土结构工程施工中存在的问题

预应力混凝土是近几十年来发展起来的一门新技术,它是在构件承受外荷载前,预先在构件的受拉区对混凝土施加预压力,这种压力通常称为预应力,提高了构件的抗裂度和刚度。但是在混凝土施工过程中施工工艺总是存在很多问题,使得施工质量有所影响,本文通过对混凝土结构工程施工工艺存在的问题的论述,提出对应工作中亟待完善的一些方面。

Scheduling a maintenance activity and due-window assignment based on common flow allowance

We study a due-window assignment problem on a single machine. The job-dependent due-windows are obtained by the common flow allowance criterion. The scheduler has the option to perform a maintenance activity which is rate modifying, i.e., improves the processing times of the following jobs. We consider a number of versions of this setting: (i) The maintenance requires a constant time, (ii) The maintenance duration is an increasing function of its starting time (linear deterioration), and (iii) The maintenance duration is position-dependent (general deterioration). We study the standard setting of regular job processing times, and investigate also the extension to position-dependent processing times. The set of potential optimal positions for the maintenance activity is fully characterized. Consequently, the problems based on all the combinations of these settings are shown to be solved in polynomial time.
