有核网络型集群中知识共享深度与知识型企业的创新资源投入关系研究

针对我国由国内小企业对大企业(国外跨国公司)的依附关系而形成的有核网络型集群.建立集群中知识溢出、知识共享所形成的不同深度组织知识和企业的私有知识对产出的影响分析模型,通过仿真计算,研究了不同知识共享深度及私有知识产出弹性对企业知识共享行为和创新资源投入的影响.研究表明,对大企业而言.只有当公共知识产出弹性超过一定阈值时,才会进行主动知识共享,且该阈值随着知识共享深度的增加而增大:且当公共知识产出弹性超过该阈值时,大企业创新投入将随公共知识产出弹性的增加而显著增加;但此时公共知识产出弹性的增加反而会抑制小企业的创新投入.相关研究结论对促进集群持续发展提供了有益的启示.

The Impact of Information Sharing and Advance Order Information on a Supply Chain with Balanced Ordering

This paper considers a supply chain with one supplier and multiple retailers that face exogenous heterogeneous end‐customer demands, where all parties utilize base‐stock policies. Each retailer is restricted to order once in every order cycle and their orders are replenished in a balanced manner within the cycle. Our study investigates the impact of information sharing and advance order information (AOI) on the supply chain. We find that the supplier benefits from the two mechanisms via two important factors, the information about observed end‐customer demands and the decision on re‐establishing the replenishment sequence. We derive the supplier's optimal sequence for stochastically comparable end‐customer demands with AOI and propose a sequencing rule for the setting with information sharing. Our numerical study examines the cost impacts of two proposed mechanisms on the entire supply chain.     

International alliance commitment and performance of small and medium-size enterprises: The mediating role of process control

Improving alliance performance is a critical issue that both managers and researchers have attempted to resolve. Recently scholars have suggested that firms can use alliance commitment and process controls to improve alliance performance. Yet research has only found weak support for these direct effects. In this paper we examine the mediating role of process controls on the relationship between alliance commitment and alliance performance. When tested on samples of SMEs we find support for our theoretical predictions. We then discuss the managerial implications of using commitment and process controls in SME international alliances.     

创新型国家的社会建构: 共识、共商、共建、共享——学习"十七大"报告的一点体会

学习胡锦涛同志在"十七大"上的报告中关于"建设创新型国家"的论述,我们体会到:创新型国家是落实科学发展观和构建社会主义和谐社会的战略核心;共识是其思想基础,共商是其政治保证,共建是其运行机制,共享是其价值目标.     

论当代中国马克思主义民族特色建构的途径

中国马克思主义民族特色是中国特色社会主义理论的本质所在。不断赋予当代中国马克思主义的鲜明民族特色就是要形成鲜明的中国特色社会主义理论。从马克思主义中国化的成就看，民族特色首先要重点建设特色社会主义理论的民族内容，要突出对马克思主义理论的民族性解读，要把民族精神融入当代中国马克思主义理论，使之成为民族特色的核心。所以，重视民族内容建设、民族认识方法和民族核心价值建设是构建当代中国马克思主义鲜明民族特色的主要途径。     

Interpretation of Measures for the Management of Population HealthInformation （Trial）

Whom should we believe? Aggregation of heterogeneous beliefs

We examine the collective risk attitude of a group with heterogeneous beliefs. We prove that the wealth-dependent probability distribution used by the representative agent is biased in favor of the beliefs of the more risk tolerant consumers. Moreover, increasing disagreement on the state probability raises the state probability of the representative agent. It implies that when most disagreements are concentrated in the tails of the distribution, the perceived collective risk is magnified. This can help to solve the equity premium puzzle. We show that the trade volume and the equity premium are positively correlated.

Inter-agency Information Sharing in Health and Social Care Services: The Role of Professional Culture

This article uses a literature review to examine the ways inwhich professional culture might shape inter-organizationalexchange of personal information in a health and social carecontext. The aim is to explore a simplified model of possibleinformation-sharing behaviours (‘ideal’, ‘over-open’,‘over-cautious’ and ‘chaotic’) and tosuggest that patterns of information sharing may be influencedby a number of factors. It is proposed that these factors includenot only inter-professional differences in the approach takento information sharing but also the ways in which the professionsinterrelate.     

HDDA: DataSifter: statistical obfuscation of electronic health records and other sensitive datasets

There are no practical and effective mechanisms to share high-dimensional data including sensitive information in various fields like health financial intelligence or socioeconomics without compromising either the utility of the data or exposing private personal or secure organizational information. Excessive scrambling or encoding of the information makes it less useful for modelling or analytical processing. Insufficient preprocessing may compromise sensitive information and introduce a substantial risk for re-identification of individuals by various stratification techniques. To address this problem, we developed a novel statistical obfuscation method (DataSifter) for on-the-fly de-identification of structured and unstructured sensitive high-dimensional data such as clinical data from electronic health records (EHR). DataSifter provides complete administrative control over the balance between risk of data re-identification and preservation of the data information. Simulation results suggest that DataSifter can provide privacy protection while maintaining data utility for different types of outcomes of interest. The application of DataSifter on a large autism dataset provides a realistic demonstration of its promise practical applications.
