The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.

好的表演需要好的观众——顾客察觉准确性在员工情绪劳动影响中的作用

基于385对顾客和员工的问卷调查的配对数据，考察了员工的情绪劳动如何影响顾客的信任和忠诚，以及顾客察觉准确性在其中的调节作用。研究结果表明员工的深层表演会促进顾客的信任，进而促进顾客忠诚；顾客对深层扮演的高察觉准确性会加强员工的深层扮演与顾客信任之间的正向关系，而当顾客对表面扮演察觉准确性低时，员工的表面扮演会对顾客信任有正向的影响；顾客的深层/表面扮演察觉准确性加强了深层/表面扮演、顾客信任和忠诚之间的中介效应。研究帮助从情绪的视角更好地理解服务情境中信任的前因变量，发现顾客的察觉准确性在情绪劳动影响过程中的重要作用，有助于服务企业从情绪劳动的角度来建立顾客信任和忠诚。     

探讨基础设施PPP项目的全生命周期的动态项目管理

当前,PPP模式不仅在我国基础设施建设中发展前景良好,同时在很多国家得到了广泛应用。相比传统的工程项目建设模式,PPP项目具有风险因素复杂和风险较大的特征,因此,PPP项目的成功会在很大程度上受动态项目管理的有效性影响。对项目管理来说,尤其是动态项目风险管理,应贯穿于PPP项目的全生命周期,而只有实现全生命周期的动态风险管理,才能使PPP模式在我国基础设施建设领域中成功利用。     

咸阳城区表层土壤重金属污染特征及生态健康风险评价

在咸阳市区采集表层土壤样品60个,包括交通主干道路两侧、城市公园、住宅小区、工矿企业周边区域4类典型功能区。采用原子吸收分光光度法测定土壤样品中Cr(铬)、Cu(铜)、Ni(镍)、Pb(铅)、Zn(锌)5种重金属的含量,运用污染指数评价法、潜在生态风险指数法对土壤重金属的污染现状及风险进行评价。结果表明:(1)咸阳市土壤中Cr、Cu、Ni、Pb、Zn 5种重金属的平均含量分别为65.11、26.91、29.81、38.26、90.94mg/kg,均超过陕西省土壤重金属元素背景值;不同城市功能区土壤重金属含量水平具有明显的差异。(2)从土壤重金属单因子污染指数来看,除重金属Pb在城市公园为中度污染外,其余元素在不同功能区及整个咸阳市均为轻度污染;从土壤重金属综合污染指数来看,不论是咸阳市还是不同功能区,其土壤环境质量等级均属于轻污染。(3)不论是综合潜在生态风险还是单个重金属元素潜在生态风险,咸阳市及不同功能区都属于低生态风险水平,且重金属Pb对综合潜在生态风险的贡献率最大(37.56%)。(4)5种重金属(Cr、Cu、Ni、Pb、Zn)对儿童和成人的非致癌风险均很小;人体(儿童和成人)暴露土壤中,Ni的综合致癌风险在可接受范围内,但明显高于下限值,而Cr的综合致癌风险则是显著的;人体(儿童和成人)暴露土壤重金属而产生的非致癌风险和致癌风险的主要途径是直接摄入和皮肤接触。     

基于两次平衡计算的南昌市耕作层土壤剥离再利用空间配置研究

研究目的:探讨耕作层土壤剥离再利用空间配置思路与方法,并以南昌市为例进行实证研究,为相关工作提供借鉴。研究方法:提出基于线性规划及OD成本矩阵方法的两次平衡计算的耕作层土壤剥离再利用土方空间配置思路。首先,确定剥离、覆土优先度并结合供求关系划定供需圈,在供需圈内部进行第一次调配平衡;其次,对于内部不能平衡的供需圈,进行第二次跨圈调配平衡,达到缩短运输距离,控制成本目的。研究结果:(1)南昌市耕作层剥离量能够满足覆土数量与质量的需求;(2)空间配置结果共划定18个供需圈,供需圈内土方调配加权平均运输距离为6 682 m,小于期望值10 km,满足项目实施要求;(3)共有15个供需圈存在土方量不平衡问题,跨圈调配的距离平均为72 071 m,满足短距离运输的要求。研究结论:以耕作层土壤剥离、覆土优先度及供求关系为基础划定供需圈,基于线性规划及OD成本矩阵的两次平衡计算的空间配置思路与方法,可以优化运输距离,减少运输成本,提高项目实施效益。本文提出的空间配置思路可以为耕作层剥离再利用工程的顺利实施提供理论与方法借鉴。

Brand Loyalty Versus Store Loyalty: Consumers’ Role in Determining Dependence Structure of Supplier–Retailer Dyads

Purpose: This article aims to integrate consumers into a channel dependence framework and explores the influence of consumers’ brand loyalty and store loyalty on the dependence structure within the supplier–retailer relationship. It also examines effects of the dependence structure on perceived conflict.

Methodology/approach: The authors test the proposed triadic relationship model among department store, supplier, and consumer by collecting matched data from both retailers and consumers in a Chinese retailing channel of sports and leisure apparel. Polynomial regression in conjunction with a response surface analysis (RSA) approach is used to test the hypotheses.

Findings: The results indicate that consumers’ brand loyalty positively affects retailer’s dependence on supplier, while consumers’ store loyalty positively affects supplier’s dependence on retailer. In addition, the retailer’s dependence is higher when consumers’ brand loyalty is higher than store loyalty; the supplier’s dependence is higher when consumers’ store loyalty is higher than brand loyalty; and the retailer’s dependence increases with the increase of both consumers’ brand and store loyalty when consumers’ brand and store loyalty are equal. Moreover, supplier’s dependence has a negative linear effect on retailer’s perceived conflict, whereas retailer’s dependence has an inverted U-shape effect on perceived conflict. A retailer would perceive more conflict when the retailer is relatively more dependent on the supplier; but the symmetrical interdependence has no significant effect on retailer perceived conflict.

Research implications: Researchers are encouraged to explore channel behaviors from a network perspective. Consumers, in particular, should be included in research frameworks related to channel dependence and behaviors. Suggestions for further research on the effects of dependence on the conflict are also proposed.

Originality/value/contribution: This study goes beyond the dyadic paradigm by integrating consumers into the framework of the channel dependence structure. It develops and tests a mechanism of consumers’ brand and store loyalty influencing dependence structure within a supplier–retailer dyad. It also enriches the literature of channel conflict by exploring the effects of retailer and supplier unilateral dependence on retailer perceived conflict with RSA methods.

Practical implications: The article provides several insightful implications for managers in understanding and managing interdependence structure in business-to-business marketing, especially in supplier–retailer relationships.
