Multilevel model of management support and casino employee turnover intention

This study proposed and tested a trickle-down model that manager support at the functional department level affect frontline employees' attitudes toward supervisor support at the operational level and subsequently influence leader-member exchange (LMX), organizational citizenship behavior (OCB), and turnover intentions. Three mediators were identified from the cross-level analysis, namely, supervisor support, group trust, and OCB. A survey collected valid responses from 336 line level casino employees who represent 112 work groups from 39 departments nested in 17 casinos. The hierarchical linear model (HLM) results indicate that (1) supervisor support mediates the relationship between departmental support and individual level LMX, (2) group trust mediates the relationship between supervisor support and hence employee turnover intention, and (3) OCB mediates the relationship between LMX and employee turnover. Our findings have important implications for casino management and operators by developing an efficient management support system to reduce the intention of frontline employees to quit.     

How group efficacy mediates the relationship between group affect and identification

This study examines the mediating role of group efficacy on the relationship between group affect and group identification by integrating the collective cognition process. Using a sample of forty-seven work groups in Study 1, the results show that group efficacy fully mediates the relationship between positive and negative group affect and group identification. Study 2 applies a two-wave panel design to verify the impact of group efficacy on group identification. The results of Study 2 indicate that group efficacy relates positively to the development of group identification. The implications for theory and practice are discussed.     

Knowledge sharing in revenue management teams: Antecedents and consequences of group cohesion

The practice of Revenue Management has received widespread acceptance in the international hospitality industry yet a lack of best practice in terms of organizational integration persists. This paper follows the notion that revenue management is first and foremost a human activity, dependent on knowledge exchange and concerted decision within revenue management teams. One critical attribute of effective teams is group cohesion. The authors contrasted communication networks of 38 revenue management teams by means of social network analysis to identify the antecedents and consequences of group cohesion. It was found that industry employment, age and revenue management experience define the structure of communication networks and that awareness of other's expertise is central in explaining differences team performance across the sample. The findings highlight the issue of knowledge asymmetry in teams and suggest that the Revenue Manager occupies a more active role as an information broker in order to enhance group decision making.     

机制设计视角的O2O模式科学性分析

O2O模式的升级与转型是目前电商行业的热点问题。运用机制设计理论,分析O2O不同经营类型的科学性,验证不同O2O类型与盈利模式间的关系。理论分析发现:相对于独立型与复合型团购,平台型团购能够较好地处理传统营销中买卖双方的信用关系,具有机制设计上的优势性。实证分析显示:平台型团购的盈利模式侧重于新型的增值业务收入,独立型与复合型团购侧重于商品的进销差价等传统盈利模式,消费者投诉绝大部分集中在独立型与复合型团购。

Is There a Viable Market for Area-Based Crop Insurance?

The performance of area yield insurance and farm-level multiple peril crop insurance is analyzed for cotton and soybean production in Georgia and South Carolina. The analysis improves on many previous studies by utilizing actual farm-level yield data and by comparing the two types of insurance products not only for actuarially fair premium rates but also for actual unsubsidized and subsidized premium rates. Results suggest that, even in heterogeneous production regions, area yield insurance may be a viable alternative to farm-level insurance when premium rates for farm-level insurance contain large positive wedges.     

我国高被引作者群体属性研究

高被引作者是国家或地区最具影响力的科研群体,体现了国家或地区知识创新的制高点。利用中国引文数据库,对我国前100名高被引作者群体属性进行统计分析,并得出相应结果。从基本属性看,我国高被引作者平均发文量349篇,平均年龄64岁,集中于苏、浙、沪地区;从教育属性看,博士研究生已成为我国科技研究的主力军,且数量持续扩大,第一学历颁发单位较为分散,最后学历颁发单位较为集中;从研究领域看,自然科学仍占绝对优势;从流动性看,我国高被引作者流动性较好,但同时也存在一定程度的学术近亲繁殖现象;从职业属性看,绝大多数高被引作者集中在高校及科研院所,普遍缺少企业从业经历,且承担着较重的行政职务及较多的社会兼职。     

中原城市群产业、人口与土地非农化时空耦合协调性研究

［目的］研判中原城市群城市化发展中产业非农化、人口与城市化土地非农化等多要素之间的耦合协调性与时空演变特征,为中原城市群健康发展提供参考和依据。［方法］文章利用耦合协调度模型、ArcGis空间分析,基于2006—2016年研究时段,评价中原城市群产业、人口与土地非农化的沟壑协调性。［结果］（1）从时序特征看,中原城市群人口、产业和土地非农化之间的耦合协调度呈总体下降、过程波动的变化趋势,其中2006年、2011年和2016年的耦合协调度分别为057、053和055,处于中度耦合协调阶段。（2）从空间特征看,中原城市群产业、人口与土地非农化的耦合协调性空间格局经历了由环形到“T”字型再逐渐形成“三点”式的分布特征,空间差异明显。［结论］中原城市群健康发展应强化城市协同发展,增强引领示范作用; 增强自主发展能力,缩小区域发展差距; 优化产业空间格局,推动城市全面发展是未来城市化协调发展的启示。
