The impact of leader safety communication on work engagement under pandemic: The effect of OBSE and anxiety based on COVID-19.

Introduction: The outbreak of COVID-19 has a great impact on employees daily work and psychology. Therefore, as leaders in organization, how to alleviate and avoid the negative impact of COVID-19 so that employees can maintain a positive working attitude has become a problem to be worthy paying attention. Methods: In this paper, we adopted a time-lagged cross-sectional design to test our research model empirically. The data from a sample of 264 participants in China were collected using existing scales in recent studies, and were used for testing our hypothesizes. Results: The results show that leader safety communication based on COVID-19 will positively affect employees' work engagement (b = 0.47, p < 0.001), and organization-based self-esteem plays a full mediating role in the relationship between leader safety communication based on COVID-19 and work engagement (0.29, p < 0.001). In addition, anxiety based on COVID-19 positively moderates the relationship between leader safety communication based on COVID-19 and organization-based self-esteem (b = 0.18, p < 0.01), that is, when anxiety based on COVID-19 is at higher level, the positive relationship between leader safety communication based on COVID-19 and organizational-based self-esteem is stronger, and vice versa. It also moderates the mediating effect of organization-based self-esteem on the relationship between leader safety communication based on COVID-19 and work engagement as well (b = 0.24, 95% CI = [0.06, 0.40]). Discussion: Based on Job Demands-Resources (JD-R) model, this paper investigates the relationship between leader safety communication based on COVID-19 and work engagement, and examines the mediating role of organization-based self-esteem and the moderating role of anxiety based on COVID-19.

The Relationship Between Perceptions of Leader Hypocrisy and Employees' Knowledge Hiding Behaviors: Testing a Moderated Mediation Model.

Purpose: Knowledge-sharing is critical for the survival and development of today's organization, but employees are not always willing to share their knowledge and sometimes even hide it intentionally or unintentionally. Taken from the leadership perspective, this paper aims to investigate the influence of leader hypocrisy on employees' knowledge-hiding behaviors. Drawing on the self-determination theory (SDT), this paper explores the mediating role of basic psychological needs satisfaction, as well as the moderating effect of employees' interdependent self-construal on the relationship between basic psychological needs satisfaction and knowledge-hiding behaviors. The moderated mediation effect is also tested. Methods: The data were collected from companies located in mainland China. The data sample for analysis consists of 336 employees. Hierarchical regression analysis was adopted to test the hypotheses of our proposed model. Results: Leader hypocrisy are positively related to knowledge-hiding behaviors (b = 0.490, p < 0.01). Basic psychological needs satisfaction plays a partial mediating role in such relationship (b =0.118, [0.056, 0.210]). The interdependent self-construal moderates the relationship between basic psychological needs satisfaction and knowledge-hiding behaviors (b = 0.134, p < 0.01), as well as the moderated mediation effect (BootSE = 0.018, [-0.083, -0.009]). Conclusion: The results show that leader hypocrisy is positively related to knowledge-hiding behaviors, and basic psychological needs satisfaction partially mediates such relationship. The interdependent self-construal weakens the negative relationship between basic psychological needs satisfaction and knowledge hiding.

Evaluation of Regional Ecological Efficiency and Intelligent Decision Support for Sustainable Development Based on Environmental Big Data.

To promote urbanization in the next stage, it is of great significance to explore the ecological efficiency of green ecological regions and advance the sustainable development of a social economic system. However, spatial heterogeneity has not been fully considered in the existing evaluation models or methods for regional ecological efficiency (REE), and the corresponding decisions on sustainable development are not the optimal solutions. To solve the problems, this paper explores the evaluation of REE and intelligent decision support for sustainable development by analyzing environmental big data. Firstly, the spatiotemporal evolution of REE was examined based on environmental big data to clarify the spatial layout of REE and the sources of the spatial differences. Next, a multiobjective optimal decision-making model was established for the sustainable development of a regional ecosystem, and the solving method was presented for the model. The proposed model was proved valid through experiments.

The Relationship Between Employee's Status Perception and Organizational Citizenship Behaviors: A Psychological Path of Work Vitality.

PURPOSE: Studies have shown that status-based rankings exist within almost every human social group and influence most aspects of organizational life. However, few studies have discussed the relationship between employees' status and organizational citizenship behaviors (OCBs). Based on social cognitive theory, this paper explores the relationship between employees' status perception and two types of OCBs: challenging and affiliative, as well as the mechanism underlying this relationship by introducing work vitality as the mediator and dominance motivation as the moderator. METHODS: We collected the empirical data from different enterprises located in major cities in China following a two-stage sampling procedure. The final sample consists of 330 employees. Hierarchical multiple regression analysis was used to test the hypothesis. RESULTS: Employee status perception is positively related to work vitality (b = 0.103, p = 0.027), challenging OCBs (b = 0.160, p < 0.001) and affiliative OCBs (b = 0.105, p = 0.006). Work vitality mediates the relationship between employee status perception and challenging OCBs with 95% bias-corrected confidence intervals [0.004, 0.063], and it also mediates the relationship between employee status perception and affiliative OCBs with 95% bias-corrected confidence intervals [0.004, 0.049]. The interaction of status perception and dominance motivation is significantly related to work vitality (b = 0.121, p = 0.041). Specifically, when dominance motivation is at low level, the effect of status perception on work vitality is -0.008 (non-significant); when dominance motivation is high level, the effect is 0.175 (p = 0.005). CONCLUSION: The result suggests that employees' perceptions of status are positively and significantly related to their challenging and affiliative OCBs, and employee's work vitality mediates this relationship. It further indicates that dominance motivation moderates the relation between status perception and work vitality. Specifically, the positive relationship between employee status perception and work vitality is stronger when an employee has high dominance motivation than low dominance motivation.

The Influence of Transactive Memory System on Individual Career Resilience: The Role of Taking Charge and Self-Promotion.

The transactive memory system is known as an effective group cognitive system as well as a knowledge-sharing structure for organizations to keep competitive advantages in today's dynamic and knowledge-based business environment. However, its influence at the individual level remains vague. The purpose of this study is to explore the influence of a transactive memory system (TMS) on individual career resilience through the theoretical perspective of conservation of resources theory (COR). This research proposes and examines a moderated mediation model that elaborates how a transactive memory system affects individual career resilience. A two-stage empirical study was conducted among 328 employees from companies in China. The findings suggest that a transactive memory system significantly influences individual career resilience positively, and employee taking-charge behavior plays a mediating role in that relationship. Furthermore, the results supported our moderated mediation model, which indicates that individuals with high self-promotion motives are more likely to engage in taking-charge behavior than those with low self-promotion motives, and the former reported higher career resilience than the latter eventually. Theoretical and practical implications are also provided in the discussion section.

How Does Leader Narcissism Influence Employee Voice: The Attribution of Leader Impression Management and Leader-Member Exchange.

Recently, the influence of leader's personality traits on employee behavior has become an emerging research area. Leaders play a crucial role in any organization because team members look up to them for policy and behavioral guidelines. Based on the social exchange theory, this study is focused on the relationship of employee-perceived leader narcissism and employee voice behavior. Through the analysis of 239 questionnaires, we find that leader narcissism has a significant influence on the motivation of leadership impression management. The narcissistic leader uses impression management that is more likely to have self- serving purpose rather than pro-social motivation. This motivation impacts leader-member exchange (LMX) quality which influences employee voice behavior. This study has significant theoretical and practical implications as it is the first study that empirically verifies the stated relationship in this under-researched area.
