Biases in Accounting and Nonaccounting Information: Substitutes or Complements?

This paper studies how bias in nonaccounting and in accounting information should be related. Bias in accounting information is modeled, as in some recent literature, as an alteration in the relative information content of accounting numbers. The optimal bias in one type of information is shown to be a complement of the bias in the other type. This result can be applied in various settings to explain a number of phenomena.     

歧口18-1油田断阶型浊积扇沉积特征研究

歧口18-1油田发育典型滑塌浊积扇。根据岩相、测井相以及粒度特征,浊积扇划分为内扇、中扇、外扇亚相。影响浊积扇形成和分布的主要包括因素断层的幕式活动、洪水事件和古地形。浊积扇单个扇体分布面积小,但沿同生断层下降盘会形成一系列的浊积扇群;单期砂体厚度薄,但继承性好,多期叠置,累计砂层厚度大;生、储、盖配置关系好,油气充满度高。     

Assembly information modelling and sequences generation algorithm of autobody

This paper attempts to formalise the assembly information of autobody and solve all feasible assembly sequences. In this paper, an assembly information model is built by using polychromatic sets and the mathematic forms of these models are given. The model is described by locating relation equations which express the constrained relationship of locating and displacement interference equations which express the constrained relationship of possible displacement. At first, the assembly information model is used to model the assembly information of autobody; then according to locating relation equations and displacement interference equations, all feasible assembly sequences can be derived. Finally, a case study illustrates the application of the proposed assembly information model. The proposed assembly information model and sequences generation approach is successfully demonstrated by autobody assembly planning, and could facilitate assembly sequence optimisation under a robust and reliable situation.     

When are assets complementary? star scientists,strategic alliances,and innovation in the pharmaceutical industry

To answer the question of when are assets complementary, we investigate specific resource combinations along the value chain, focusing on two mechanisms that are central to combining resources for innovation in the pharmaceutical industry: recruitment and retention of star scientists, and 2) engagement in strategic alliances. We propose that resource combinations that focus on the same parts of the value chain are substitutes due to knowledge redundancies. Conversely, we hypothesize that resource combinations that link different parts of the value chain are complements due to integration of nonredundant knowledge. To test these hypotheses, we empirically track the innovative performance of 108 global pharmaceutical firms over three decades (1974–2003). Copyright © 2011 John Wiley & Sons, Ltd.     

Exclusivity in licensing alliances: using hostages to support technology commercialization

We examine why exclusivity provisions are used in licensing alliances, and when restrictions in licensing scope (e.g., by product or geography) accompany these exclusivity provisions. We find broad support for the proposition that these features are associated with the contractual challenges of allying with licensees when they contribute valuable complementary capabilities toward the commercialization of licensed technologies. Evidence from our data suggests that exclusivity is used as a contractual hostage to safeguard licensee investments in complementary assets and to enable contracting over early stage technologies. Scope restrictions are employed to balance the tradeoffs between the value creation made possible by licensee complementary capabilities and the transactional hazards entailed in working exclusively with licensees. Our results also suggest that scope restrictions and other formal safeguards may be substitute mechanisms for managing similar transactional concerns in licensing alliances.

中泰水果贸易互补性研究

2003年6月中国与泰国签署了《中国—东盟全面经济合作框架协议》"早期收获"方案下加速取消关税的协议。该协议规定自当年10月起,中泰两国的蔬果产品取消关税。泰国成为中国在中国—东盟自由贸易区框架下的第一个实行水果产品零关税的国家。而在中国与泰国的水果贸易中,双方都拥有自身的优势产品,通过对RCA指数和贸易互补性的指数的测量来具体分析中国与泰国水果贸易中的贸易互补性问题。     

植物基因克隆的方法

基因克隆技术是挖掘新基因、分离控制植物重要性状基因的有效手段。随着拟南芥、番茄、杨树等植物全基因组测序的完成,标志着植物基因组的研究进入到了后基因组的时代,研究植物基因功能、表达、调控成为今后研究的热点,因此基因克隆技术应用将更加广泛。本文主要介绍了图位克隆、转座子标签克隆、同源克隆、表达序列标签等植物基因克隆的方法,并对其原理、应用及研究进展做了简单阐述。     

差序格局视阈下的农村精神养老问题探析

老有所养、老有所乐是国人不懈追求的理想。“乐”是养老的重要一面，老年人作为社会人，同样有相应的精神和情感需要。以孔子和蒂特马斯的思想为基础，阐述精神养老的重要性；从费孝通的差序格局出发，论述农村的差序格局是精神养老的载体；分析差序格局中血缘、地缘、业缘因素在农村精神养老中发挥的重要作用。
