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 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.

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.

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 findings also reveal that expectation, perceived enjoyment and perceived ease of use have significant impact on satisfaction. Moreover, it is found that perceived enjoyment, perceived ease of use and satisfaction significantly influence the repurchase intention of Bitcoin.

This study encourages future comparative studies to be conducted. Besides, it is recommended to find out other possible antecedents of repurchase intention. Moreover, this study suggested negative effects of Bitcoin to be explored.

In a practical standpoint, this study provides valuable suggestions about cryptocurrencies use and regularization. For instance, education and learnability issues of novice users need to be considered. Further, the regularization/implementation of cryptocurrencies/blockchain technologies is also suggested.

This is the pioneer endeavor which investigates the repurchase intention of Bitcoin. The findings explore some of the possible antecedents which influence repurchase intention of Bitcoin. These findings provide valuable insights and enrich the existing body of literature in the domain of Bitcoin.

This study aims to investigate the impact of transformational leadership on the innovation of small and medium enterprises (SMEs) through employee voice behaviors. Drawing from the upper echelon theory, it is hypothesized that employee voice is the mediating mechanism through which transformational leadership affects the process and product innovation in SMEs.

Data was collected from 169 SMEs of Pakistan through an online self-administered questionnaire. The proposed hypotheses were tested using partial least squares structural equation modeling (PLS-SEM).

Findings confirm that transformational leadership positively affects both process and product innovation in SMEs and employee voice behavior mediates between these relationships.

This research contributes to both theoretical and practical domains by providing evidence that encouraging employees to raise their voice positively impacts product and process innovation and transformational leadership is a potential organizational factor to shape employee voice and process and product innovation. To the best knowledge, this is the first study that investigates the mediating role of employee voice between transformational leadership and process and product innovation in SMEs and developing country’s context.

Employee voice has emerged as a strong predictor of positive organizational outcomes. Grounding the theoretical model in resource-based theory; this study conceptualizes how high-performance work system (HPWS) can enhance organizational innovation of small and medium enterprises (SMEs) through voice behaviors. Specifically, the purpose of this paper is to empirically test if employee voice mediates the relationship between HPWS and organizational innovation.

This study used a quantitative strategy and cross-sectional survey method for the collection of data from SMEs operating in Pakistan. A list of SMEs was obtained from the federal government organization responsible for the development of SMEs in Pakistan. A self-administered structured questionnaire was distributed and 239 randomly selected SMEs responded to the survey.

Findings confirmed the conceptualized model and revealed that HPWS was significantly and positively related to employee voice and organizational innovation. Employee voice was found as a significant predictor of organizational innovation and mediating factor in the relationship between HPWS and organizational innovation.

This study is limited in terms of variables included in the conceptual model and relatively small size of the sample that was derived from a single federal organization. More variables and SMEs can be included in future studies to get broader results and, potentially, better findings.

SME managers/owners can design HR function in such a way that employees will be encouraged to raise their voice and participate more in the organization. Scholars should study voice behaviors distinct from citizenship behaviors.

This study is the first of its kind to conceptualize the relationship between HPWS, employee voice, and organizational innovation in SMEs of Pakistan.

The purpose of this study, thermal radiation and viscous dissipation impacts on double diffusive convection on peristaltic transport of Williamson nanofluid due to induced magnetic field in a tapered channel is examined. The study of propulsion system is on the rise in aerospace research. In spacecraft technology, the propulsion system uses high-temperature heat transmission governed through thermal radiation process. This study will help in assessment of chyme movement in the gastrointestinal tract and also in regulating the intensity of magnetic field of the blood flow during surgery.

The brief mathematical modelling, along with induced magnetic field, of Williamson nanofluid is given. The governing equations are reduced to dimensionless form by using appropriate transformations. Numerical technique is manipulated to solve the highly nonlinear differential equations. The roll of different variables is graphically analyzed in terms of concentration, temperature, volume fraction of nanoparticles, axial-induced magnetic field, magnetic force function, stream functions, pressure rise and pressure gradient.

The key finding from the analysis above can be summed up as follows: the temperature profile decreases and concentration profile increases due to the rising impact of thermal radiation. Brownian motion parameter has a reducing influence on nanoparticle concentration due to massive transfer of nanoparticles from a hot zone to a cool region, which causes a decrease in concentration profile· The pressure rise enhances due to rising values of thermophoresis and thermal Grashof number in retrograde pumping, free pumping and copumping region.

To the best of the authors’ knowledge, a study that integrates double-diffusion convection with thermal radiation, viscous dissipation and induced magnetic field on peristaltic flow of Williamson nanofluid with a channel that is asymmetric has not been carried out so far.

The purpose of this paper is to explore the black box between high-performance work systems (HPWS) and innovation performance in small- and medium-sized enterprises (SMEs). Through application of the ability, motivation and opportunity (AMO) framework, the study examines the mediating roles of innovation-specific ability, motivation and voice behaviors between HPWS and SMEs’ innovation performance.

The hypotheses are tested on data collected through a self-administered questionnaire from 237 SMEs in Pakistan.

Findings indicate that human capital, motivation and employee voice fully mediate the relationship between HPWS and innovation performance in SMEs.

The cross-sectional research design and self-reported measures warrant caution for the interpretation of findings. Future research may consider a longitudinal research design and objective measures.

SMEs need to invest in the adoption and implementation of HPWS that will develop innovation-specific abilities, motivation and voice behaviors simultaneously among employees that will lead to higher innovation performance.

This is the first study of its kind utilizing an AMO framework to investigate the underlying mechanism through which HPWS affect innovation performance in SMEs.
