This study aims to explore the adverse impacts of abusive supervision on helping behaviors among employees, as mediating by intention to leave and moderating by Islamic work ethics (IWE).

A quantitative approach was employed, and the sample consisted of 283 nurses working in various public sector hospitals in Pakistan. The data analysis was conducted using SPSS and AMOS with the PROCESS macro.

The results suggest that abusive supervision diminishes helping behavior among nurses. Additionally, the study reveals that intention to leave mediates the relationship of abusive supervision and nurses' helping behavior. Moreover, the introduction of IWE as a boundary condition reveals that the mediated link is weaker when IWE is higher, and vice versa.

This study provides valuable insights for hospital authorities to develop intervention strategies and policies aimed at reducing abusive supervision in hospitals. Hospital management should also be aware of the detrimental effects of abusive supervision on nurses' helping behaviors, which can be mitigated by promoting ethical values aligned with IWE.

This study makes a valuable contribution to the limited research on the link between abusive supervision and helping behaviors in hospital settings. It offers new perspectives by incorporating the Conservation of Resources theory, particularly within the healthcare sector. Furthermore, this research expands the current knowledge by investigating the mediating influence of intention to leave and the moderating effect of IWE in mitigating the adverse impact of abusive supervision on nurses' helping behavior in Pakistan's public sector hospitals.

This study, based on the conservation of resource theory, aims to investigate the negative impacts of abusive supervision on helping behaviors among employees by examining the mediating role of rumination and the moderating role of psychological flexibility.

A total sample of 282 reliable questionnaires are collected from 282 employees working in education and banking sectors of Pakistan. SPSS and AMOS are used for data analysis of the proposed model.

The findings reveal that rumination mediates the relationship between abusive supervision and employees’ helping behavior. In addition, the results show that higher levels of psychological flexibility negatively moderate the relationship between abusive supervision and employees’ helping behaviors through mediation.

This study elucidates how and when abusive supervision deters helping behavior among employees and provides useful guidelines for banking/university’s administration to understand harmful consequences of abusive supervision and take appropriate policy measures to lessen their harmful effects upon employees.

By proposing a moderated mediation model, this study discovers rumination as a key mediator that links abusive supervision to employees’ helping behaviors and identifies the role of psychological flexibility in diminishing the negative impacts of abusive supervision upon employees’ helping behaviors through rumination.

This study, based on social exchange theory, aims to explore knowledge hiding behavior in relation to shared goals of individuals working in teams and trust (cognitive-based trust and affective-based trust) as a boundary condition on shared goals and knowledge hiding relationship.

A total sample of 270 reliable questionnaires are collected from university students in China. SPSS and AMOS are employed for the data analysis of the proposed model.

Findings of the study have indicated that shared goals are negatively associated with knowledge hiding behavior. Furthermore, trust (cognitive-based trust and affective-based trust) moderates the relationship between shared goals and knowledge hiding behavior.

This study has provided empirical proof and in-depth understanding and recommendations for supervisors and administrative authorities to form the culture of groups/teams with shared goals to reduce the undesirable individual behaviors.

This study, among the first empirical studies investigating the relationship between shared goals and knowledge hiding behavior, trust as a moderator, enriches the existing academic literature of and provides valuable insight into the research on knowledge hiding and knowledge management.

This study, based on social exchange theory, aims to explore the association between appreciative leadership and employees' helping behaviors by investigating the mediation role of emotional reactions (pride, anxiety), and choosing organizational trust as a boundary condition between appreciative leadership and helping behaviors.

A total sample of 285 reliable questionnaires were collected in three time lags from employees working in the Pakistani education and banking sectors. PROCESS macro using SPSS and AMOS are employed for data analyses of the proposed model.

The findings reveal that appreciative leadership has positive impacts on employees' helping behaviors and emotional reactions (pride, anxiety) mediate the relationship of appreciative leadership and employees' helping behaviors. In addition, the results show that high organizational trust strengthens the positive relationship between appreciative leadership and employees' helping behaviors.

This research has provided empirical proof between the relationship of appreciative leadership and helping behaviors and the findings are of great significance for managers, employees, and organizations. The study proposes that leaders should have appreciative behavior while treating their subordinates. Moreover, it is revealed that the role of organizational trust should be given more attention and importance because it is a factor moderating the employees' helping behaviors.

The present study, among the first empirical efforts investigating the relationship between appreciative leadership and helping behaviors, organizational trust as a moderator, enriches the existing academic literature of and provides worthy insight into the research on appreciative leadership and helping behaviors.

Morality in the workplace has become a significant determinant of organizational effectiveness and employee well-being. This research aims to conduct an in-depth review of the past literature on multidimensional morality and provide insight into its impact on the modern workplace and employee well-being.

The literature search resulted in 3,589 papers published between 2012 and 2024. This paper analyzed 30 research studies on workplace morality based on predetermined inclusion and exclusion criteria to ensure methodological rigor.

Research findings show the need to promote workplace ethics to avoid counterproductive workplace behaviors. Also, effective leadership adheres to ethical principles, together with the ethical framework of an organization, which includes codes of ethics and a commitment to corporate social responsibility, contributing to the overall well-being of individuals by providing a sense of support and resolving conflicts. Ethical conflicts are associated with decreased well-being and increased turnover, underscoring the need for organizational solutions.

Understanding intricate morality is essential for organizations to foster moral cultures and improve performance. HR specialists can use this knowledge to create policies that uphold moral principles and improve employee job satisfaction.

This study extends the current body of knowledge by synthesizing research on multifaceted moral issues in modern workplaces. It provides useful insights for researchers, practitioners, and policymakers who are interested in promoting ethical organizational cultures by addressing ethical shortcomings.

Tantalum is a kind of metal material with moderate hardness, high ductility, small thermal expansion coefficient, excellent corrosion resistance and outstanding biocompatibility. The purpose of this study is that its tribological performance could be tested and analyzed so as to use it in different fields.

The friction resistance of a-Ta under dry friction conditions was tested at different roads. The relationships between load and friction coefficient, wear rate and two-dimensional shape of wear scars were studied.

The stable Ta₂O₅ film with lubrication effect was generated in the process of friction. And, the larger the test load, the more Ta₂O₅ would be generated.

This work lays a theoretical foundation for tantalum as an excellent wear-resistant material.

Cryptocurrencies, such as Bitcoin, generate innovative and fast exchanges without any physical form and facilitate online payments; thus, they may bring about revolutions of the future economic system. Recent investigations reveal that China, the second largest Bitcoin market, accounts for a huge volume of Bitcoin trading and mining, which can cast distinct influences on future values of Bitcoin. Therefore, it would be of great significance to probe into the repurchase intention of Bitcoin of the Chinese individuals.

One hundred and forty-three questionnaires were collected from Chinese respondents. SPPS was employed for data analysis of the proposed hypotheses.

The results show that expectation has a positive impact on perceived enjoyment and perceived ease of use. A positive relationship between perceived ease of use and perceived enjoyment was confirmed.

The purpose of this study is to prepare WC-10Co-4Cr coatings using two processes of plasma spraying and high-velocity oxygen fuel (HVOF) spraying. The decarburization behaviors of the different processes are analyzed individually. The microstructural characteristics of the as-sprayed coatings are presented and the wear mechanisms of the different WC–10Co–4Cr coatings are discussed in detail.

The WC–10Co–4Cr coatings were formed on the surface of Q235 steel by plasma and HVOF spraying.

Plasma spraying causes more decarburizing decomposition of the WC phase than HVOF spraying. In the plasma spraying process, η(Cr25Co25W8C2) phase appears and the C content decreases from the top surface of the coating to the substrate.

In this study, two WC–10Co–4Cr coatings on Q235 steel prepared by plasma and HVOF spraying were compared with respect to the sliding wear behavior.

The wear mechanisms of the plasma- and HVOF-sprayed coatings were abrasive and oxidation, respectively.

The chapter evaluates how the demise of cryptocurrencies as a medium of exchange may result from the issue of digital money by central banks. To evaluate the likelihood that central bank digital money would cause the demise of cryptocurrencies, the research employs discourse analysis and literature review. In this chapter, I demonstrate how the issuing of a digital currency by a central bank might result in the demise of private digital currencies like bitcoin. I contend that central banks will make use of their monetary authority and the confidence that people have in currency guaranteed by the government. This might provide considerable motivation for central banks to launch their own digital money. The creation of a digital currency by a central bank has the potential to reduce confidence in cryptocurrencies, which might eventually cause them to collapse. The chapter is the first to argue that fiat digital money should prevail over private digital currency.
