The purpose of this paper is to investigate dynamics of causal interactions and financial risk contagion among BRICS stock markets under rare events.

Two methods are adopted: The new causal inference technique, namely, the Liang causality analysis based on information flow theory and the dynamic causal index (DCI) are used to measure the financial risk contagion.

The causal relationships among the BRICS stock markets estimated by the Liang causality analysis are significantly stronger in the mid-periods of rare events than in the pre- and post-periods. Moreover, different rare events have heterogeneous effects on the causal relationships. Notably, under rare events, there is almost no significant Liang's causality between the Chinese and other four stock markets, except for a few moments, indicating that the former can provide a relatively safe haven within the BRICS. According to the DCIs, the causal linkages have significantly increased during rare events, implying that their connectivity becomes stronger under extreme conditions.

The obtained results not only provide important implications for investors to reasonably allocate regional financial assets, but also yield some suggestions for policymakers and financial regulators in effective supervision, especially in extreme environments.

This paper uses the Liang causality analysis to construct the causal networks among BRICS stock indices and characterize their causal linkages. Furthermore, the DCI derived from the causal networks is applied to measure the financial risk contagion of the BRICS countries under three rare events.

While cyberloafing has emerged as a prevalent issue in numerous workplaces, research on its consequences is still underdeveloped, highlighting a need for further exploration and analysis. Drawing upon the cognitive appraisal theory of emotion, this study investigates the influence of coworkers' cyberloafing on employees' workplace incivility, mediated by negative emotions and moderated by task interdependence.

In Study 1, the hypothesized research model was tested utilizing three-wave time-lagged survey data collected from 333 employees and their coworkers. In Study 2, an additional sample of 274 employees was surveyed. Data were analyzed using hierarchical regression analysis and the bootstrap method.

The results indicated that coworkers' cyberloafing positively influenced employees' workplace incivility, with this relationship mediated by negative emotions. Additionally, task interdependence was found to positively moderate both the direct relationship between coworkers' cyberloafing and negative emotions and the indirect path from coworkers' cyberloafing to employees' workplace incivility through negative emotions.

This study helps managers gain a deeper understanding of cyberloafing's effects, enabling them to manage and curb it more effectively.

Prior research has predominantly explored the effects of cyberloafing on its implementers. However, this study innovatively shifts focus to the observer perspective, empirically demonstrating whether and how coworkers' cyberloafing affects employees' workplace incivility, enriching and expanding the existing literature.

Taking the subordinates’ perspective, this paper aims to explore the supervisor-subordinate relationships and how daily interactions, personal ties and connections with the supervisors contribute more significantly, positively or negatively, to the subordinates’ well-being.

This exploratory study is based on the thematic analysis of data collected from two rounds of in-depth semi-structured interviews with 21 participants in a Portuguese utility company.

The subordinates’ perceptions of the nature and quality of their relationships with supervisors were found to have considerable effects on well-being. Positive effects were identified when subordinates feel emotionally supported and believe that supervisors truly care about them and are genuinely willing to listen to their concerns, but the most significant effects on the subordinates’ well-being are produced when the perceived authenticity of the supervisor allows the relationship to evolve into a state of relational closeness, and the subordinates connect with the person-as-real, the human being behind the mask who is playing the supervisory role. These findings reflect features of the cultural setting where the study was conducted.

The study provides evidence to support the argument that a better understanding of supervisor-subordinate relationships and their effects on well-being requires an integrated approach that considers the valuable contributions of different literatures and theoretical frameworks and the multiple dimensions of that relationship, including personal and non-work dimensions. This approach is particularly relevant in cultural contexts where these dimensions might play a critical role in work relations.

Tomando la perspectiva de los subordinados, el artículo explora las relaciones supervisor-subordinado y cómo las interacciones diarias, los vínculos personales y las conexiones con los supervisores contribuyen de manera más significativa, positiva o negativamente, al bienestar de los subordinados.

Este estudio exploratorio se basa en el análisis temático de los datos recopilados en dos rondas de entrevistas semiestructuradas en profundidad con veintiún participantes en una empresa de servicios públicos portuguesa.

Se encontró que las percepciones de los subordinados sobre la naturaleza y calidad de sus relaciones con los supervisores tienen efectos considerables en el bienestar. Se identificaron efectos positivos cuando los subordinados se sienten apoyados emocionalmente por los supervisores y creen que realmente se preocupan con elles y están genuinamente dispuestos a escuchar sus preocupaciones. Los efectos más significativos en el bienestar de los subordinados se producen cuando la autenticidad percibida de los supervisores permite que la relación evolucione hacia un estado de cercanía relacional, y los subordinados se conectan con la persona real, el ser humano detrás de la máscara, que es el supervisor.

Este estudio proporciona evidencia que respalda la idea de que una mejor comprensión de las relaciones supervisor-subordinado y sus efectos en el bienestar requiere un enfoque integrado que tenga en cuenta las valiosas contribuciones de diferentes literaturas y marcos teóricos y las múltiples dimensiones de esa relación, incluidas las dimensiones personales y no laborales, para dar sentido a las relaciones supervisor-subordinado en contextos culturales donde podrían desempeñar un papel fundamental.

A partir da perspectiva dos subordinados, o artigo explora as relações supervisor-subordinado e como as interações diárias, os laços pessoais e as ligações com os supervisores contribuem de forma mais significativa, positiva ou negativamente, para o bem-estar dos subordinados.

Este estudo exploratório baseia-se na aplicação da análise temática aos dados recolhidos em duas rondas de entrevistas semiestruturadas e em profundidade a vinte e um participantes, em exercício de funções em empresa portuguesa de serviços públicos.

Os dados recolhidos permitem concluir que as percepções dos subordinados sobre a natureza e a qualidade das suas relações com os supervisores têm efeitos consideráveis no bem-estar. Foram identificados efeitos positivos quando os subordinados sentem que os supervisores os apoiam emocionalmente e realmente se preocupam com os subordinados e estão genuinamente dispostos a ouvir as suas preocupações. Os efeitos mais significativos no bem-estar são obtidos quando dos subordinados percepcionam a autenticidade do supervisor, permitindo que o relacionamento evolua para um estado de proximidade relacional, e os subordinados se conectam com a pessoa real, o ser humano por detrás da máscara: o supervisor.

O estudo fornece evidência que permite sustentar o argumento segundo o qual uma melhor compreensão das relações supervisor-subordinado e dos seus efeitos no bem-estar exige uma abordagem integrada que tenha em conta as contribuições valiosas de diferentes literaturas e quadros teóricos e as múltiplas dimensões da relação supervisor-subordinado, incluindo a dimensão pessoal e não profissional, particularmente relevantes em contextos culturais em que estas podem desempenhar um papel crítico.
