Asymmetric Network Interconnection

We develop a model of competition between interconnected networks,that allows for carriers to differ in size. Under two-partpricing, we show that because of asymmetry the larger network willalways prefer a reciprocal interconnection charge be set at cost.For sufficiently large asymmetry the smaller network will have thesame preference. Under the assumptions of our model a particularly simple regulation is optimal – if carriers cannot agree on the terms of interconnection, the larger carrier is entitled to select the access price which is then applied reciprocally.     

冷链物流“最后一公里”快速配送方法研究

冷链物流“最后一公里”的品质配送,对于实现全程冷链以及提升企业形象有着重要的意义。为了实现冷链物流的快速配送,本文提出了一种基于复杂网络的“最后一公里”物流配送区域划分方法。该方法构建了现实生活中物流配送的复杂网络模型,然后基于两阶段的LinkRank社区发现算法实现了物流配送区域的划分,最后建立了一套完善的物流配送体系。该体系明确了配送中转站以及配送点所覆盖的区域,这些区域所包含的社区物流关系紧密、易于配送。本文通过案例研究,验证了方法的有效性,最终方案可有效提高“最后一公里”的配送效率和降低物流成本。     

创业成长中双重网络嵌入的演化规律研究——以正泰集团和温氏集团为例

新企业在创建、存活和成长过程中,需要通过嵌入社会关系网络获得资源支持,嵌入产业网络获得产业链分工协作收益。创业网络是社会网络和产业网络的有机统一体,创业成长过程同时也是对社会网络与产业网络双重嵌入的过程。基于创业网络中信任关系从情感性信任到认知性信任再到复合信任的演进,新创企业的双重网络嵌入性关系演化呈现出以下规律性:一是由社会网络嵌入向社会网络和产业网络双重嵌入演化;二是由"交易性嵌入"方式向"关系性嵌入"方式演化;三是由双重网络分离式嵌入向叠加式嵌入演化。新创企业双重网络嵌入演化对创业成长有促进作用,但同时也会形成"创业网络经营成本",政府需要对此加以重视。     

Adaptation and inertia in dynamic environments

Research summary : We address conflicting claims and mixed empirical findings about adaptation as a response to increased environmental dynamism. We disentangle distinct dimensions of environmental dynamism—the direction, magnitude, and frequency of change—and identify how selection shapes adaptive responses to these dimensions. Our results show how frequent directional changes undermine the value of exploration and decisively shift performance advantages to inert organizations that restrict exploration. In contrast, increased environmental variance rewards exploration. Our results also show that, in dynamic environments, the best‐performing organizations are generally more inert than less successful organizations. Managerial summary : Our research helps managers to understand under what business conditions investments into exploration and strategic flexibility are more likely to pay off. Dynamic business environments characterized by persistent trends and by large, infrequently occurring structural shocks reward strategic pursuit of temporary advantage. Thus, exploration and strategic flexibility are preferred strategies. In contrast, the challenge in frequently changing environments with fleeting opportunities is to identify and to focus on strategic actions whose payoffs on average are high, independent of environmental volatility. Low levels of exploration and long‐term strategic focus are preferred strategies in these circumstances. Copyright © 2015 John Wiley & Sons, Ltd.     

The impact of socialist imprinting and search on resource change: a study of firms in lithuania

Firms in transition economies experienced a large exogenous shock in their external business environment in the late 1980s when these economies moved from a socialist‐oriented economic environment to a more market‐oriented economic environment. This paper examines the following research question in the context of this change: What are some factors that influence transition economy firms to successfully change their operating know‐how or knowledge sets to reflect the demands of their new environment? Building on some core ideas from literature on organizational imprinting, knowledge‐based view of the firm, and firm search, we suggest that two factors have a profound impact on a firm's ability to change. The imprinting effect of firms' prior socialist institutional and market environment adversely impacts their ability to change their operating knowledge. At the same time, firms that search for new knowledge from distant sources (located in mainly non‐socialist countries) are able to successfully change their knowledge to meet the demands of the new market‐oriented economy. Both of these aspects also have joint interdependent effects on the success of change; distant search mitigates some of the adverse impact of socialist market imprinting, but that is not the case for the impact of socialist institutional imprinting. These findings have interesting implications for both researchers and practitioners involved in transition economy settings. Copyright © 2006 John Wiley & Sons, Ltd.     

Interpartner legitimacy in regional strategic networks

Our aim is to add to the knowledge on a network level, focusing on if, and how, interpartner legitimacy affects the success or failure of network formation and development processes. Existing network theories and research tend to focus on resource exchange rather than on how actors perceive each other in terms of being legitimate or not. The purpose of the article is to analyze the interpartner legitimacy's influence on the formation and development processes of regional strategic networks (RSNs) from a network level. Two Swedish cases are discussed in terms of pragmatic, moral and cognitive interpartner legitimacy. The cases and the following discussion illuminate that interpartner legitimacy is important to incorporate into the analytical model if we wish to understand the processes of negotiations on the rules and norms which set the possibilities for survival of multi-actor interactions.     

私营企业主的关系网络与社会支持

基于对武汉市31位私营企业主的深度访谈,本文对私营企业主的关系网络与社会支持进行了深入的研究。研究发现:(1)私营企业主的客户群体所拥有的文化资本、权力和经济资源都远远高于其他的群体,而亲戚群体则相对比较低。(2)亲戚在情感和资金方面支持力度最大;员工在工作和业务拓展方面贡献更多;客户在业务拓展和资讯支持方面的作用都是最大的;朋友在信息和情感支持上的作用突出。(3)私营企业主的大部分关系网络是在不断交往和互动过程中建立起来的,吃饭、娱乐和聊天是他们之间互动的主要形式。(4)私营企业主最想结识的是政府官员群体,随后才是客户群体,托人打招呼、请吃饭和送礼是他们建立关系网络最有效的手段。     

领导成员交换与员工创造力：情感机制的中介作用

情感是员工创造力的重要前因,而已有文献结论存在不一致,且未深入地探讨影响员工情绪的组织情境因素。文章依据情感事件理论,分析和检验了领导成员交换、积极/消极情感与创造力的关系,以及组织创造力支持感的调节作用。通过分析442对主管〖CD*2〗下属配对样本,结果表明：积极情感和消极情感在领导成员交换与创造力关系之间起部分中介作用;组织创造力支持感正向调节积极情感与创造力的关系,而对消极情感与创造力关系的负向调节作用不显著;最后,高的组织创造力支持感还调节积极/消极情感在领导成员交换与员工创造力关系间的中介作用。     

Fairness,legal compliance,and organizational commitment

Attribution theory is used to hypothesize a positive relationship between one's perception that a fairness motive underlies personnel/human resource management activities and one's organizational commitment. The hypothesis is tested via a survey of 48 operating managers in a Midwestern department store chain. Using hierarchical regression to control for job satisfaction and length of service, a significant positive relationship exists between commitment and the perception that a fairness motive underlies personnel/human resource management activities. Commitment is not significantly related to the perception that a legal compliance motive underlies the activities.     

A fresh look at the contribution of project management to organizational performance

A better understanding of organizational performance and the contribution that project management can make is the aim. The article adopts the “Competing Values Framework,” a rich framework that is well established both theoretically and empirically but is not well known in the field of project management. The framework is summarized and applied in an empirical investigation of the contribution of project management in general and project management offices (PMOs) in particular to organizational performance. The examination of 11 case studies revealed multiple concurrent and sometimes paradoxical perspectives. The criteria proposed by the framework have been further developed through the identification of a preliminary set of empirically grounded performance indicators. The empirical results contribute to a better understanding of the role of project management generally and PMOs specifically. They also demonstrate the usefulness of this framework for the study of project management's contribution to organizational performance.
