What matters for work engagement? A diary study on resources and the benefits of selective optimization with compensation for state work engagement

This diary study addresses the benefits of employees' daily use of selective optimization with compensation (SOC) for state work engagement. We hypothesized that day‐level SOC not only directly fosters work engagement but that SOC also reveals its beneficial effects for work engagement in interaction with both external and internal resources. Specifically, we proposed SOC substitutes for job control, role clarity, and state of being recovered, thus helping employees manage low daily levels of these resources. We tested our hypotheses with a sample of 138 employees who completed two daily surveys over a total of 545 workdays. Results of multilevel analyses revealed that SOC benefits work engagement in both proposed ways. First, day‐level SOC was positively related to state work engagement. Additionally, day‐level role clarity and state of being recovered predicted state work engagement, but day‐level job control did not. Second, SOC benefitted state work engagement by offsetting low levels of role clarity and being recovered, and by boosting job control in their respective relationships with work engagement. The results suggest that by using SOC at work, employees can actively enhance their own work engagement on a given workday. This knowledge provides promising starting points for the development of interventions.     

Bhopal disaster—a personal experience

Bhopal Gas Tragedy was the worst industrial accident in the world where several thousand persons lost their lives. It occurred at the Union Carbide plant located inside the city of Bhopal and close to the railway station, at midnight of December 2-3, 1984 due to the leakage of MIC gas which took the local sleeping and floating population unawares.

This paper describes the experience of a transit passenger who reached the Bhopal Railway Station by train at about the same time when the deadly gas leakage occurred.     

大型水利水电工程实施占用耕地补偿制度的思考

本文在分析长江三峡工程用地特点的基础上。对大型水利水电工程实施耕地补偿制度中的问题和困难进行调查研究，认为应从新的视角来认识大型水利水电工程的耕地占补平衡问题。进而探索耕地补偿制度实施的新途径和新方式。应在耕地总量动态平衡政策适当调整的基础上．将“以地补地”和“缴费补地”的方式相结合。既通过土地整理．在提商土地质量的前提下增加耕地的有效面积：又要落实耕地开垦费．扶持库区的土地整理。从而使库区的耕地占补制度顺利实施。     

激励相容理论视角下生态公益林补偿对农户的增收效应——以福建三明为例

基于福建三明499户农户的实地调查数据,用倾向得分匹配法测算了生态公益林现金直接补偿和岗位性补偿对农户的增收效应,结果表明：现金直接补偿和岗位性补偿对生态保护和农户增收都是正效应。现金直接补偿对农户增收效应不显著,而岗位性补偿对农户家庭总收入和家庭人均收入的净效应分别达55.4%和57%。进一步研究发现,两种补偿方式对贫困户和非贫困户的增收效应也不尽相同,其中现金直接补偿不利于贫困户增收,而岗位性补偿对不同收入的农户都具有正向显著增收效应。此外,从生态公益林的根本使命出发,可以发现现金直接补偿和岗位性补偿对生态保护的净效应也存在较大差异。故此,科学规划生态补偿方式和补偿标准是实现生态保护和农户增收双重效应的根源所在。     

中国沿海省市海洋生态补偿效率评价

本文运用考虑非期望产出的超效率SBM模型、DEA-Malmquist指数模型、Tobit模型和标准差椭圆模型,对2006-2016年中国11个沿海省市的海洋生态补偿效率开展测度和分析,结果显示：2006~2016年中国总体海洋生态补偿效率平均值为0.633,处于中等效率水平,随时间呈“下降-上升-稳定”的趋势;海洋生态技术进步依旧是海洋生态补偿过程中全要素生产率的重要驱动力,但面临一定的技术效率损失;海洋第三产业比重对海洋生态补偿效率值有正向的显著影响,城市化率、进出口总额占比和海洋灾害直接经济损失对海洋生态补偿效率存在显著的负向影响;海洋生态补偿效率的空间聚集性增强,区域不平衡性有所收敛,空间分布格局基本保持稳定.     

矢量毫米波系统中非线性补偿技术研究

目的针对矢量毫米波系统中因传输链路和光电转换带来的非线性问题,提出一个基于维特拉级数的非线性均衡方案。方法首先给出该方案的基本原理,然后搭建一个射频载波频率为40 GHz、传输信号为5Gbaud 16QAM的矢量毫米波仿真系统,分析基于维特拉级数的非线性模型各阶非线性项的贡献,并比较在不同传输距离情况下,该方案相对于仅采用线性均衡方案对系统性能的提升。结果在传输距离为10 km时,该方案能够将平台误码率降低到10~(-3)以下。结论该方案明显提升了系统的性能。
