The Impact of Spiritual Leadership on Employee’s Work Engagement--A Study Based on the Mediating Effect of Goal Self-Concordance and Self-Efficacy

The average stress of people in China’s workplace is reaching the peak in recent two years.To improve employee’s positive psychological factors,Spiritual leadership has a good performance in this regard.Based on the mediating effect of goal self-concordance and self-efficacy,this paper further studies the impact of spiritual leadership on employee’s work engagement.Through the empirical study,the following conclusions are drawn:(1)Spiritual leadership significantly positively affects the employee’s work engagement.(2)Spiritual leadership has a significant positive effect on goal self-concordance and self-efficacy.(3)Goal self-concordance and self-efficacy have significant positive effects on employee’s work engagement.(4)Goal self-concordance and self-efficacy play a partial mediating role in the process of spiritual leadership’s impact on employees’work engagement.This study found the new mediator which partly revealed the mechanism between the effectiveness of Spiritual Leadership and employee’s work engagement.This study may serve as one of the researches for improving the effectiveness of leaders in organizations and promoting the motivation of employees in the workplace.

Goal Self-Concordance Model: What HaveWe Learned and Where are We Going

Goal self-concordance reflects self-generated personal goals aligning with people’s interests and core values in one’s implicit personality as organic components,which is measured by the“perceived locus of causality”PLOC.Pursuing and achieving self-concordant goals both predict diversified outcomes in need-satisfaction,mental and physical well-being,positive attitude and behavior,etc.Based on expounding and sorting out the concept and measurement about goal self-concordance,the author analyzes the differences among a series of goal self-concor-dance theories.This paper focuses on the latest research trends and summarizesfive influencing aspects of goal self-concordance:mental health,cognition,emotion,personal will,and behavioral outcomes.The mediating effects are discussed concerning antecedents and influence effects,the influence effects are shown in three aspects including the characteristics of individual,target,and environment.While the antecedent effects are respectively reflected in self-insight,personality,empowerment,and self-supported environment,content,and context of the goal itself.Finally,the author proposes several potential research interests from a broader perspective based on the current literature.

基于局部self-concordant障碍函数的全牛顿步多项式时间算法(英文)

由Nesterov和Nemirovski^([4])创立的self-concordant障碍函数理论为解线性和凸优化问题提供了多项式时间内点算法.根据self-concordant障碍函数的参数,就可以分析内点算法的复杂性.在这篇文章中,我们介绍了基于核函数的局部self-concordant障碍函数,它在线性优化问题的中心路径及其邻域内满足self-concordant性质.通过求解此障碍函数的局部参数值,我们得到了求解线性规划问题的基于此局部Self-concordant障碍函数的纯牛顿步内点算法的理论迭代界.此迭代界与目前已知的最好的理论迭代界是一致的.

Polynomial-time interior-point algorithm based on a local self-concordant finite barrier function

The choice of self-concordant functions is the key to efficient algorithms for linear and quadratic convex optimizations, which provide a method with polynomial-time iterations to solve linear and quadratic convex optimization problems. The parameters of a self-concordant barrier function can be used to compute the complexity bound of the proposed algorithm. In this paper, it is proved that the finite barrier function is a local self-concordant barrier function. By deriving the local values of parameters of this barrier function, the desired complexity bound of an interior-point algorithm based on this local self-concordant function for linear optimization problem is obtained. The bound matches the best known bound for small-update methods.
