Extant scholars identified negative workplace gossip as a social stressor that negatively influences employees’ behavior and attitude. Despite the burgeoning interest in workplace stressors, limited studies have explored how the detrimental consequences of targets’ perceived negative workplace gossip spur their emotions and behaviors. Grounding on conservation of resources and ego depletion theories, this study aims to investigate why and how targets’ negative workplace gossip may contribute to trigger knowledge hiding. Specifically, the authors explore the underlying mechanism of personal ego depletion and boundary conditions of organizational justice to shed new light on the above process.

Using two time-wave survey, the authors collected 340 sample data from employees working in high-tech companies of China. Hierarchical regression analysis was used to examine hypothesized relationships of moderated mediation model.

The empirical results revealed that negative workplace gossip exacerbates knowledge hiding by increasing personal ego depletion. Furthermore, through testing moderated mediation model, the results showed that organizational justice (i.e. distributive and procedural justice) with the low presence moderates the stronger strength of the linkage between negative workplace gossip and personal ego depletion, and likewise, it also moderates the stronger effect of negative workplace gossip on knowledge hiding via personal ego depletion.

This study recommends several guidelines for managers and practitioners to mitigate negative gossip by strengthening organizational justice.

This study first enriches novel understanding in the literature between negative workplace gossip and knowledge hiding by using a new emotional mechanism (i.e. personal ego depletion). This research also contributes new insights by incorporating contextual boundary conditions (i.e. organizational justice) that have not been yet researched on negative gossip and knowledge hiding linkage.

Despite the recent extending research on knowledge hiding, there is still scant research on social stressor phenomena-related contextual antecedent factors and new cognitive mechanisms of knowledge hiding behaviors. To shed new light on this unexplored gap, this research explores the multi-level moderated mediation model that examines how and when negative gossip experienced by targets in the workplace induces their knowledge hiding from coworkers drawing from the lens of social learning and cognitive theories. More specifically, this study aims to evaluate the relationship between negative workplace gossip and knowledge hiding via moral disengagement, and this mediation effect is also moderated by team relational conflict as a novel boundary condition.

This study collected multi-wave 338 employees’ data from 68 teams of cross-sectional industries in China, which were nested within teams. The collected nested nature data were analyzed by employing multi-level analysis based on hierarchical linear modeling.

The results suggested that negative workplace gossip first triggers moral disengagement and thereby, leads to knowledge hiding. Furthermore, the direct positive association between negative workplace gossip and moral disengagement was strengthened by increasing intra-team relational conflict. In addition, the mediation effect of moral disengagement between negative workplace gossip and knowledge hiding was also strengthened through increasing intra-team relational conflict.

This study first empirically examines the multi-level model using a new underlying mechanism (moral disengagement) and team-level boundary condition (relational conflict) and enriches the current literature on knowledge management and workplace gossip. Theoretical and practical implications of these findings and future research lines are also discussed, which will facilitate practitioners and academicians to curb counterproductive knowledge behavior.

Despite the abundant literature on panic buying during COVID-19 pandemic, the several causes and consequences of panic buying have been enormously ignored. The purpose of this study is to emphasize the consumer’s behavior during the COVID-19 pandemic and illustrate the comprehensive theoretical model of consumers’ panic buying to investigate its causes and consequences in a developing country empirically to uncover this gap.

The authors collected data from 419 households of all socioeconomic classes of Bangladesh. A hierarchical regression model analyzed the data.

This study finds that internal and external factors such as rumors, government strategies, fear and anxiety and health security significantly affect consumers’ panic buying behaviors. This finding supports some theories of human behavior. This study also finds that panic buying has internal and external consequences such as price hike, shortage of supply of products, dissatisfaction of consumers and increase in utility (benefit) of the products but not on consumer’s budget. This finding supports as well as contradicts some established theories of human and consumer behavior.

This study proves that panic buying cannot help the consumers and they are the ultimate sufferers of this. The findings of this study will help the government, media, suppliers and consumers to interact properly to maintain panic buying during a pandemic crisis. Giving a holistic explanation of the causes and consequences of panic buying by introducing some novel variables is a momentous strength of this study.

While the rapid adoption of information communication technologies (ICT) in organizations has been linked with a higher risk of cyberbullying, research on the influence of cyberbullying on interpersonal behaviors in the workplace remains limited. By drawing on the ego-depletion theory and the leader-member exchange (LMX) theory, this research investigates how, why and when workplace cyberbullying may trigger interpersonal aggression through ICT.

The authors collected data from 259 employees and 62 supervisors working in large ICT organizations in China through a multi-wave survey. The authors performed multilevel analysis and used hierarchical linear modeling to test the proposed moderated mediation model.

The results revealed that workplace cyberbullying has a significant and positive influence on interpersonal aggression in the workplace via ego depletion. The authors found that differentiation in LMX processes at group level moderates the indirect relationship between workplace cyberbullying and interpersonal aggression (via ego depletion). Furthermore, the positive indirect effect of workplace cyberbullying was found to be stronger in the presence of a high LMX differentiation condition in comparison to a low LMX differentiation condition.

The data were collected from Chinese ICT organizations, which may limit the generalization of this study’s findings to other cultural and sectoral contexts.

This paper provides the first step in understanding how, why and when workplace cyberbullying triggers interpersonal aggression by investigating the role of ego depletion as a mediator and LMX differentiation as a boundary condition. This is the first study to empirically examine the relationships between workplace cyberbullying, ego depletion, LMX differentiation and interpersonal aggression in ICT organizations using multi-level modeling.

This chapter examines the contributions that the Indian political leader and educator, Mahatma Gandhi (1869–1948) can make to the United Nations Educational, Scientific and Cultural Organization (UNESCO) led practice of Global Citizenship Education (GCE) and a sustainable world. It discusses issues related to the cognitive, socio-emotional, and behavioural dimensions of learning to know, learning to be, and learning to do involving a critical analysis of what it means to be and become an active citizen. This work expands on a long-term study on selected thinkers that suggests that there are political implications of taking action based on values, such as, peace and non-violence. Challenges often emerge when one takes action in real-world politics, and there are merits in studying the modes of creativity displayed by actors who are embroiled in these successes and challenges. Among the examples of such thinkers is Gandhi, the leader of one of the largest non-violent mass movements in the recent history of India with a significant influence abroad. As discussed in this chapter, a critical engagement with studies on the patterns of living of people and communities across Western/non-Western diasporas that are based on values, such as peace and non-violence, can help develop intercultural understandings and enhance education for citizenship. The chapter examines value-creating global citizenship education as a pedagogical approach to learning that has been developed as an outcome of studies on Gandhi and other Asian thinkers.

We compare our findings to previous research and discuss implications for the future evolution of the global leadership field.

This study aims to understand tourists’ travel intention during the COVID-19 pandemic by using the theory of planned behavior (TPB) with additional causal links and moderators. The three research objectives of this study are to explore basic causality, mediating effects of attitude and moderating effects of age and perceived risk, of the extended TPB model, respectively.

An online survey was conducted in Taiwan during the COVID-19 pandemic. In total, the survey generated 351 responses. The structural model analysis was performed to test the cause-and-effect relationships in the traditional TPB model and the mediating role of an individual’s attitude regarding travel during the COVID-19 pandemic. The SmartPLS multi-group analysis procedure was applied to test the moderation effects of age and perceived risk.

It is found that the perceived behavioral control is the main contributor of travel intention for the traditional TPB while attitude partially mediates the relationship between subjective norm and travel intention for the test of mediation. Also, moderation tests confirm that both age and perceived risk show significant moderating effect only on subjective norm to travel intention relationship.

The novelty of this research is that this study proposed and verified the mediating influence of attitude and two additional paths, the moderating influence of age and perceived risk, which deepened the understanding of the TPB model and the impact of COVID-19 on travel intention. Because TPB model is context-dependent, using one mediating and two moderating variables allows the study to understand how TPB functions in a different situation.

游客旅游意图：以年龄及感知风险为调解因素态度为中介因素重新审视TPB模型

本研究旨在通过使用计划行为理论 (TPB) 以及额外的因果关系和调节因素来了解 COVID-19 大流行期间游客的旅游意图。本研究的三个研究目标分别是探索 TPB 扩展模型的（1）基本因果关系、（2）态度的中介效应、和（3）年龄和感知风险的调节效应。

本研究在台湾COVID-19大流行期间, 进行了一项线上调查。该调查共收集了351份回复问卷。本研究以结构模型分析测试传统 TPB 模型中的因果关系及个人对 COVID-19 大流行期间旅行态度的中介作用。本研究也应用了 SmartPLS 多组分析程序来测试年龄和感知风险的调节作用。

本研究发现感知行为控制是传统TPB旅行意愿的主要贡献者, 而态度在中介测试中部分中介了主观规范与旅行意愿之间的关系。此外, 本研究在调节测试中证实, 年龄和感知风险均仅对旅行意愿关系的主观规范显示出显着的调节作用.

本研究独创之处在于提出并验证了态度的中介效应, 以及年龄和感知风险的调节效应这两条附加路径, 加深了对 TPB 模型的理解以及 COVID-19 对旅行意愿的影响。由于 TPB 模型是上下文相关的, 因此本研究使用一个中介变量和两个调节变量可以让未来研究了解 TPB 在不同情况下的功能。

Intención de viajar de los turistas: revisitando el modelo TPB con la edad y el riesgo percibido como moderadores y la actitud como mediadora

Este estudio tiene como objetivo comprender la intención de viajar de los turistas durante la pandemia de COVID-19 mediante el uso de la teoría del comportamiento planificado (TPB) con vínculos causales y moderadores adicionales. Los tres objetivos de investigación de este estudio son explorar (1) la causalidad básica, (2) los efectos mediadores de la actitud y (3) los efectos moderadores de la edad y el riesgo percibido, del modelo TPB extendido, respectivamente.

Se realizó una encuesta online en Taiwán durante la pandemia del COVID-19. En total, la encuesta generó 351 respuestas. El análisis del modelo estructural se realizó para probar las relaciones de causa y efecto en el modelo TPB tradicional y el papel mediador de la actitud de un individuo con respecto a los viajes durante la pandemia del COVID-19. Se aplicó el procedimiento de análisis multigrupo SmartPLS para probar los efectos de moderación de la edad y del riesgo percibido.

Se muestra que el control del comportamiento percibido es el principal antecedente de la intención de viajar en el TPB tradicional, mientras que la actitud media parcialmente la relación entre la norma subjetiva y la intención de viajar. Además, los tests de moderación confirman que tanto la edad como el riesgo percibido muestran un efecto moderador significativo solo en la relación entre la norma subjetiva y la intención de viajar.

La novedad de esta investigación es que este estudio propuso y verificó la influencia mediadora de la actitud y los dos efectos moderadores adicionales de la edad y del riesgo percibido, lo cual profundiza en la comprensión del modelo TPB y el impacto del COVID-19 en la intención de viajar. Dado que el modelo TPB depende del contexto, el uso de una variable mediadora y dos variables moderadoras permite comprender mejor cómo el TPB funciona en una situación diferente.

In this paper, the previously developed idea of generalized optimization of circuits for deterministic methods has been extended to genetic algorithm (GA) to demonstrate new possibilities for solving an optimization problem that enhance accuracy and significantly reduce computing time.

The disadvantages of GAs are premature convergence to local minima and an increase in the computer operation time when setting a sufficiently high accuracy for obtaining the minimum. The idea of generalized optimization of circuits, previously developed for the methods of deterministic optimization, is built into the GA and allows one to implement various optimization strategies based on GA. The shape of the fitness function, as well as the length and structure of the chromosomes, is determined by a control vector artificially introduced within the framework of generalized optimization. This study found that changing the control vector that determines the method for calculating the fitness function makes it possible to bypass local minima and find the global minimum with high accuracy and a significant reduction in central processing unit (CPU) time.

The structure of the control vector is found, which makes it possible to reduce the CPU time by several orders of magnitude and increase the accuracy of the optimization process compared with the traditional approach for GAs.

It was demonstrated that incorporating the idea of generalized optimization into the body of a stochastic optimization method leads to qualitatively new properties of the optimization process, increasing the accuracy and minimizing the CPU time.
