Effects of perceived overqualification on career distress and career planning: Mediating role of career identity and moderating role of leader humility

In this study, we examined how perceived overqualification influences employees' career distress and career planning. Specifically, we drew on role identity theory to hypothesize that perceived overqualification is positively related to individuals' career identity. Based on internal self-processing dynamics of role identity, we further hypothesized that career identity predicts reduced career distress and increased career planning. We expected career identity to mediate the effects of overqualification on career distress and career planning. Based on the symbolic interactionism perspective of identity, we hypothesized that this mediation is moderated by leader humility so that overqualified employees exhibit stronger career identities in the presence of a humble leader. We found support for our hypotheses in a multi-wave time-lagged study of 220 supervisor–subordinate dyads from 50 groups. Overall, our studies highlight that perceived overqualification can have positive effects on employees and organizations under appropriate management conditions. We discuss theoretical and practical implications of these results.     

浅谈流动性沙漠油气集输管道保护措施

地处于塔克拉玛干沙漠腹地的西部某油田由于地处沙漠地区,常年风沙天气,各类油田集输管道在运行过程中,出现了裸露、移位、穹起、扭曲、剪切等多种情形,直接威胁集输管道的安全运行。为了避免这些问题的出现,从管线全生命周期来进行管理,通过设计、施工、运行、维护等几方面对流动性沙漠地区的管道运行提出一些保护措施,经过现场实践应用表明,这些措施切实可行,可为以后的压力管道管理提供借鉴。     

The paradoxical mechanisms of high‐performance work systems (HPWSs) on perceived workload: A dual‐path mediation model

We invoke conservation of resources theory to present an integrative model that simultaneously examines the positive and negative effects of employee‐experienced high‐performance work systems (experienced‐HPWSs) on perceived workload (PW). Analysis of three‐wave, time‐lagged data from 368 employees of four major state‐owned commercial banks in China revealed that experienced‐HPWSs positively predict perceived organisational support, which in turn decreases PW. Experienced‐HPWSs positively predict psychological empowerment, which in turn increases PW. The positive influence of psychological empowerment on PW is stronger than the negative influence of perceived organisational support on PW, indicating that resource loss is more salient than resource gain. This dual‐path mediation model increases our understanding of the mechanisms through which HPWSs influence PW and highlights the coexistence of opposite impacts during the process.     

多尺度绿道网络布局特征及选线量化体系建构

绿道建设是当前我国规划设计的一项热点工作,但现阶段其规划建设过程出现规划目标不明确和功能单一化的问题。首先针对绿道定义、功能的变化和规划方法的多元化特征进行论述,其次根据绿道规划的尺度特征,针对市域、中心城区和社区三个尺度,通过MSPA、大数据等数据和技术手段,分别围绕生态连通、市民出行和社会基础设施使用公平视角提出不同尺度的绿道布局特征,讨论不同尺度下绿道布局量化体系的建构。

养老保险税制的国际实践及启示

当前我国养老保险税制存在企业缴纳基本养老保险的税收优惠力度不够。企业年金税收政策不全面,个人储蓄性养老保险税制缺位,养老保险的税收监督政策不完美等问题。从国际比较角度看,鼓励性的养老保险税收政策总体上有利于扩大养老保险规模。因此。当前我国有必要加大企业缴纳基本养老保险的税收优惠力度,建立有利于调动个人建立企业年金和储蓄性养老保险的税制,同时,避免过度滥用税收优惠政策。     

发挥资本导向整合银行风险管理体制

近年来,资本管理在商业银行中的地位越来越重要,这是监管部门强调资本约束原则的效果,也是商业银行自身控制风险的重要手段。文章指出,作为商业银行风险管理工作的重要抓手,资本管理的核心是计量能力的提升,对于资本分配应掌握总量控制的原则。中国银行业应以资本管理为导向,逐步完善自身的风险管理体系。     

指令簿透明度增加与市场价格发现——基于计算实验金融方法的指令驱动市场研究

本文基于计算实验方法,在指令驱动市场的微观模拟平台基础上研究不同指令簿透明度的市场价格发现的变化规律。实验发现适度增加指令簿透明度有利于市场价格发现,但在指令簿透明度过高的市场中指令簿透明度增加后价格发现程度变化较弱甚至反而有所降低。因此,实验结果表明增加指令簿透明度并不一定会促进市场的价格发现。
