上海经济适用房的理性发展和市场走势

经济适用房解决的是中低收入群体的住房困难,而商品房市场主要是为中等收入或高收入群体改善居住条件提供资源,两者在目标客户群上有明显的不同。经济适用房虽然会对附近商品房的价格产生一定影响,但不会对全市整体房价造成很大冲击。     

矿泉水瓶再生设计研究

由于500ml左右矿泉水瓶瓶口具有统一的螺纹规格,其次,瓶体的容量也具有接近统一的标准,这就为矿泉水瓶再生设计的开发提供了必要的前提。市场上关于矿泉水瓶的再生设计多利用矿泉水瓶作为盛水的容器,而没有继续探讨其盛放小型垃圾(瓜子壳,纸屑,铅笔屑等)的功能。本文以绿色设计中延长产品生命周期的理念为原则,以联想法、模仿法及组合法等产品设计方法为指导,推出一款全新的使用矿泉水瓶衍生功能的产品,并着重介绍在本设计进行的过程中得出的新的设计方法:系统化条件下的功能衍生法。通过这款设计来说明现有产品衍生出新的功能的可行性,并总结一定的设计经验与设计方法,为以后进行相关设计奠定理论和方法基础。

Outward foreign direct investment by emerging market firms: A resource dependence logic

This study examines and extends the resource dependence logic of diversification for a better understanding of outward foreign direct investment (OFDI) activities by emerging market firms. We contend that the diversification logic is bounded by state ownership, an important but less considered component of interdependence. Our empirical results, based on panel data analysis of Chinese listed firms, suggest that the level of interdependence between Chinese and foreign firms in China in multiple forms, including symbiotic, competitive, and partner interdependencies, is positively associated with the level of the Chinese firms' OFDI activities. However, Chinese firms with higher levels of state ownership are less susceptible to the pressures imposed by foreign firms to invest abroad. Copyright © 2013 John Wiley & Sons, Ltd.     

基于线阵CCD和三维重构的盒装烟标测量装置

为客观评价盒装烟标的模切、压痕以及包装成型后的质量,基于线阵CCD(Charge-Coupled Device)和三维(Three-Dimensional)重构,设计烟标模切尺寸、角度的测量装置。通过CCD扫描拍摄图像,经过阀值分割、腐蚀、膨胀、Sobel、霍夫变换等图像处理,实现烟标边缘线的精确提取、检测。结果表明：1)测量装置的尺寸示值误差小于5 μm,不确定度为0.9 μm,角度的相对误差小于0.2%,变异系数小于0.02%;2)38个检测指标(包含模切尺寸、角度和压痕宽度)所需时间小于240 s,与传统的人工测量相比,大大提高了盒装烟标的检测效率;3)通过盒装烟标的3D重构模型,不仅直观展示了盒装烟标的成型效果,而且利用模型预测的搭口值,可对盒装烟标的外观质量进行评价。     

Is abusive supervision an absolute devil? Literature review and research agenda

Abusive supervision has received increasing attention in the field. However, few studies have qualitatively reviewed its latest developments. The current paper reviews 48 studies on abusive supervision using content analysis. We identify six emerging trends of abusive supervision, including inconsistency of abusive behaviors, comparison between perceived and objective behaviors, reciprocity, team-level climate, coworker effects, and comparisons between theoretical perspectives. Based on a review of those six trends and some emerging findings, we identify and validate the possible positive effects of abusive supervision from an integrated analysis. We also determine the moderating role that Asian culture plays in differentiating the negative and positive effects of abusive supervision. Specifically, we identify the differences between Asian and Western cultures, and then explore the moral mechanisms (i.e., violation of moral standards, conflict of moral principles) through which abusive supervision may exert positive effects in the Asian cultural context. Finally, we clarify our theoretical implications and provide suggestions for future research.     

Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition

Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities).     

管道防腐技术的质量控制与应用

因管道腐蚀穿孔而不得不重新更换管线的施工活动经常发生。从而管道腐蚀造成的损失极为巨大,所以管道腐蚀一直是困扰油田地面建设的一个重要问题。而防腐质量的好坏,直接影响着管道的使用寿命,因此,分析还氧粉末外喷涂技术在管线防腐工程中的应用情况,对防腐质量控制有着非常重要的意义。     

某省火电机组理论上网标杆电价分析

2004年国家发改委在经营期电价政策基础上推出了标杆电价政策。2007--2008年,我国煤价不断上涨。为了解发电企业的经营状况,为价格管理部门合理核定新投产火电机组标杆上网电价提供参考,开展了某省火电机组理论上网标杆电价分析工作。在收集整理分析发电企业大量经营参数的基础上,得到经营期算法模型所需的计算参数,并对经营期算法参数进行了敏感性分析。     

后金融危机时期全球创业教育与中国创业发展——基于全球创业观察最新数据分析的结论

通过2008年全球创业观察（GEM）获得的数据分析,可以认为创业的发生、发展与创业教育有很大关系。总体而言,创业教育和培训对创业能起到积极的促进作用。但创业教育的不同形式与不同来源对各国的创业所产生的作用各有不同,取得的效果也存在着差异。创业教育对创业产生的效果与其文化和价值观念、经济发展水平、社会保障体系成熟程度以及就业机会等因素有很大关系,同时与创业群体的年龄阶段、创业教育或培训的供给情况以及创业教育的质量等因素关系密切。本文在分析基础上得出的结论,为我国政府在创业教育和培训方面制定政策等提供了决策性参考依据。
