OCB and external–internal social networks: effects on individual performance and adaptation to change

In this study, we develop and test a model that links one's internal and external social network structures to his or her willingness and ability to adapt in a changing work context. Using a survey data from 371 employees working in 133 different branches of a large financial firm, we find that individual behaviors that explain task performance and individual adaptation to change are affected by a number of supportive social ties (size of the support network) with which one receives support inside and, mostly, outside the workplace. The results also show that individual performance and adaptation to change are affected by the level of workers' organizational citizenship behavior. We also identify a mediating effect exerted by the informational network structure (mostly an internal network) on the relationship between the support network (mostly an external network) and individual task performance.     

‘Who Knows What?’ in New Venture Teams: Transactive Memory Systems as a Micro‐Foundation of Entrepreneurial Orientation

The increasing importance of entrepreneurial behaviour has led scholars to embrace the idea that an entrepreneurial orientation (EO) is an important predictor of firm performance. While EO occupies a central position in strategic entrepreneurship research, scholars have yet to explore its origins in new ventures. Drawing on the knowledge‐based and cognitive views, we theorize that a new venture team's transactive memory system is a cognitive mechanism that spurs the development of an EO. In a field study of high‐tech new ventures in China, we examined the relationship between venture teams’ transactive memory systems (representing the distribution, integration, and utilization of the teams’ knowledge) and EO and the moderating influence of team‐, firm‐, and environment‐level factors. We found that the transactive memory system of a new venture team enhanced their EO and that this relationship was positively influenced by intra‐team trust, the structural organicity of a venture, and environmental dynamism. Our findings provide novel insights into the micro‐foundations of TMS in developing an EO in new ventures.     

Principles and Applications of Multilevel Modeling in Human Resource Management Research

Multilevel modeling is important for human resource management (HRM) research in that it often analyzes and interprets hierarchal data residing at more than one level of analysis. However, HRM research in general lags behind other disciplines, such as education, health, marketing, and psychology in the use of a multilevel analytical strategy. This article integrates the most recent literature into the theoretical and applied basics of multilevel modeling applicable to HRM research. A range of multilevel modeling issues have been discussed and they include statistical logic underpinning multilevel modeling, level conceptualization of variables, data aggregation, hypothesis tests, reporting mediation paths, and cross‐level interactions. An empirical example concerning complex cross‐level mediated moderation is presented that will suffice to illustrate the principles and the procedures for implementing a multilevel analytical strategy in HRM research. © 2015 Wiley Periodicals, Inc.

UNDERSTANDING MEMBER CHARACTERISTICS AND COOPERATIVE PRICE EFFECTS: THE CASE OF THE ARGENTINEAN DAIRY SECTOR

Since the 1990s, Argentinean dairy‐processing cooperatives have lost considerable amounts of members and market share. We analyse their current role by investigating the characteristics of farmers who continue delivering to them and price differentials between cooperatives and investor‐oriented firms (IOFs). A probit regression model applied to 917 farmers suggests that cooperative farmers are more disadvantaged than farmers delivering to IOFs in terms of education, farm size and productive technology. Moreover, t‐tests applied to data representing 70 per cent of national volume indicate that farmers delivering to cooperatives are between 11 per cent and 29 per cent smaller than those delivering to IOFs, depending on province. A hierarchical multilevel regression model applied to 9,720 transactions among farmers and processors shows that, after controlling for quantity and quality, cooperatives pay lower (3.5%) but more stable prices than IOFs. In a context of rapid structural change, we observe a market in which larger farmers deliver to IOFs and smaller farmers deliver to cooperatives and conclude that, at the expense of paying lower prices, cooperatives may act as buyers of last resort for otherwise disadvantaged farmers.     

珠江三角洲地区变水位滨河地区生态修复与景观营造——以佛山市东平河景观工程为例

城市滨水地区是城市生态资源、景观资源和市民活动的重点区域。以广东佛山东平河为例,首先对场地中水利建设对变水位下河滩、堤岸、植被的影响做了分析,并针对洪水、潮汐的不同影响程度采取了相应的分级设计模型构想。在实践中,根据不同水位情况,运用低洼高筑、水道疏浚、植被恢复等多种方式,通过工程、生态、景观的手段恢复了滨水自然生境,营造了活跃的公共空间,实现了水利堤岸改造、生态修复、景观营造的有机结合,让陆地和水域自然衔接、和谐共生。     

Research Frontiers in the Economics of Climate Change

Academic and policy debates over climate change risks and policies have stimulated economic research in a variety of fields. In this article I briefly discuss eight overlapping areas of current research in which further effort is particularly warranted. These areas include decision criteria for policy; risk assessment and adaptation; uncertainty and learning; abatement cost and the innovation and diffusion of technology; and the credibility of policies and international agreements. Further analysis in these areas not only will advance academic understanding but also will provide insights of considerable importance to policymakers.
