In this article we review research on Chinese guanxi and social networking in the past twenty years and identify the major perspectives, theories, and methodologies used in guanxi research at micro and macro levels. We summarize the main findings of over 200 journal articles on guanxi research in terms of its conceptual definitions and measurements, its antecedents and consequences, and its dynamics and processes. Furthermore, we identify the gaps between different levels of guanxi research and discuss future directions to advance our understanding of the complex and intricate guanxi phenomenon.

The MapReduce model is becoming prominent for the large-scale data analysis in the cloud. In this paper, we present the benchmarking, evaluation and characterization of Hadoop, an open-source implementation of MapReduce. We first introduce HiBench, a new benchmark suite for Hadoop. It consists of a set of Hadoop programs, including both synthetic micro-benchmarks and real-world Hadoop applications. We then evaluate and characterize the Hadoop framework using HiBench, in terms of speed (i.e., job running time), throughput (i.e., the number of tasks completed per minute), HDFS bandwidth, system resource (e.g., CPU, memory and I/O) utilizations, and data access patterns.

Purpose This paper proposes locational ambidexterity as a location-specific factor based on an operation flexibility perspective, and explores why and how multinational corporations (MNCs) proactively deal with uncertainty by valuing locational ambidexterity in making location decisions. Design/methodology/approach Location choice data for foreign direct investment (FDI) at a sub-national level in China is used to test the role of locational ambidexterity. Findings We find that FDI generally prefers locations with high ambidexterity. Moreover, investments from a heterogeneous country context are more sensitive to locational ambidexterity than those from a similar country context. However, there is no significant evidence that wholly owned investments favor locational ambidexterity more than do international joint ventures. Research limitations/implications An alternative operationalization of locational ambidexterity may be needed. Future research could explore the sources of locational ambidexterity, identify other firm- and industry-level factors that could alter the value of ambidexterity, investigate how MNCs integrate locational ambidexterity into organization-specific option creation strategies and test the ambidexterity perspective with micro-level location choice data. Practical implications Locational ambidexterity may reduce the overall risk and adjustment cost of future changes. FDI may choose a location with high ambidexterity, i.e. a balanced portfolio of location-specific determinants, under uncertainty about the future. Originality/value Drawing on the notion of location flexibility from Buckley and Casson (1998), this study identifies a new location character, locational ambidexterity, and proposes that MNCs address uncertainty by choosing ambidextrous locations that offer more flexibility for MNCs to change or respond to potential volatility. Selecting locations with high ambidexterity is thus an alternative and complement to the organization-specific flexibility creation strategies suggested by the literature on real option and flexibility.

We rely on the existing conflict literature and self-verification theory to examine perceived task and relationship conflict. We set out to contribute to the discussion of whether relationship conflict is dysfunctional and task conflict is functional in terms of the individual evaluations of group efficacy and group mind. Our sample is a field setting of 127 individuals within a Fortune 500 company. Individual perceptions of group efficacy and group mind scores were significantly higher when neither type of conflict was perceived to occur often as compared with when both types of conflict were perceived to occur often. After decoupling types of conflict, we found when only task conflict occurred often, the perceived efficacy and mind scores were significantly higher than when both types of conflict occurred often. This is a contradictory finding based on the existing literature that suggests task conflict negatively impacts emergent states.
