The Employee Engagement Scale: Initial Evidence for Construct Validity and Implications for Theory and Practice

Interest in the employee engagement construct has gained increasing attention in recent years. Measurement tools focused on nuanced areas of engagement (i.e., job engagement and organizational engagement) have been offered; however, no measure of employee engagement has been advanced despite persistent calls in the research. We present the development, method, and results of a three‐dimensional employee engagement measurement tool developed for use in the human resource and management fields of study. Across four independent studies, the employee engagement scale (EES) was found to consist of three subfactors (cognitive, emotional, and behavioral) and a higher‐order factor (employee engagement). Across a series of four studies, we explored the factor structure and reliability of the EES (Study 1), then refined the scale, confirmed the factor structure, and examined reliability and both convergent and nomological validity evidence (Study 2). Next (Study 3), we completed a final reduction in scale items and examined additional evidence of reliability and nomological validity as well as evidence of discriminant validity. Finally (Study 4), we tested for evidence of incremental validity. In the implications for theory and practice section, we discuss the importance of an employee engagement measure aligned alongside an agreed‐upon definition and framework. Limitations and future directions for research—such as the need for further psychometric testing and exploring issues of measurement invariance—are discussed. © 2016 Wiley Periodicals, Inc.     

城市水资源承载力与城市规模研究——以玉州—福绵—北流一体化概念规划方案为例

水资源承载能力对于一个国家、地区、城市的综合发展及发展规模至关重要,社会经济发展必须控制在水资源承载能力之内,才能通过以水资源的可持续利用实现社会经济的可持续发展。在玉州-福绵-北流一体化概念规划中,通过引入水资源承载力、生态需水量等概念,重点探讨研究了以水资源约束为特征的资源环境承载力,并以之为前提确定合理的城市规模。     

Multivariate Hill Estimators

We propose two classes of semi‐parametric estimators for the tail index of a regular varying elliptical random vector. The first one is based on the distance between a tail probability contour and the observations outside this contour. We denote it as the class of separating estimators. The second one is based on the norm of an arbitrary order. We denote it as the class of angular estimators. We show the asymptotic properties and the finite sample performances of both classes. We also illustrate the separating estimators with an empirical application to 21 worldwide financial market indexes.

财政支农研究一个文献综述

文中利用现有的中外财政支农文献,梳理出了财政支农原因、规模、结构和绩效的研究成果。总结了前人研究的两个共同点,同时也指出未来研究的两个方向。     

企业边界的协同演化机制研究

本文基于交易费用理论和资源基础观相融合的视角探讨了企业能力边界和规模边界的协同演化问题。协同演化的根本原因在于企业进行边界决策时需要对交易费用和知识整合成本进行综合的权衡,这直接体现在如何实现知识基础与产品范围的匹配上。总之,实现两者匹配的模式共有九种,相应的企业边界协同演化的表现形式也有九种。每一个企业都会根据自身的情况从中选择适合的边界演化形式。柯达公司的案例对此提供了说明。     

公共支出转型及其对经济发展影响的协整分析

基于政府职能转变视角,考察了公共支出转型中规模与结构变化,并对其经济发展效应进行了协整分析。研究发现:我国公共支出已经由经济建设型转向公共服务型;预算内经济建设支出的名义GDP占比与经济发展水平之间存在较显著的正相关关系;预算内公共服务支出的名义GDP占比与经济发展水平显著负相关;预算内支出的名义GDP占比与经济发展水平为反向变动关系;基本公共服务支出长期能够促进经济发展。     

林业规模经济的非线性均衡分析研究

本文将林业规模经济分为两类,即林业经济效益的规模经济和林业三大效益的规模经济。在分析林业经济效益的规模经济时,引入了成本变量,简要说明了林业经营成本与林业经济效益成反向变动关系。在分析林业三大效益的规模经济问题时,运用非线性均衡分析方法,并通过建立模型论证了林业三大效益达到最大化即均衡状态时所必需的条件。对林业三大效益规模经济问题的分析是本文核心部分,旨在为林业三大效益均衡问题的研究提供若干参考依据,同时也为林业合作经济组织的发展提供指导。     

团体规模、动态激励和社会链接对团体贷款影响的实证分析

本文通过实证分析,考察了团体规模、动态激励、社会链接三个重要因素对团体贷款的影响。结果表明:团体规模对团体贷款效率的影响并不显著,较大的规模更易诱发道德风险,但能降低团体总体风险;动态激励对团体贷款的有效运行具有重要作用;社会链接对团体贷款效率具有重要影响,强的社会链接可以诱致更高但不够稳定的还款意愿。
