Abstract
Purpose
The current analysis produces the fractional sample of non-Newtonian Casson and Williamson boundary layer flow considering the heat flux and the slip velocity. An extended sheet with a nonuniform thickness causes the steady boundary layer flow’s temperature and velocity fields. Our purpose in this research is to use Akbari Ganji method (AGM) to solve equations and compare the accuracy of this method with the spectral collocation method.
Design/methodology/approach
The trial polynomials that will be utilized to carry out the AGM are then used to solve the nonlinear governing system of the PDEs, which has been transformed into a nonlinear collection of linked ODEs.
Findings
The profile of temperature and dimensionless velocity for different parameters were displayed graphically. Also, the effect of two different parameters simultaneously on the temperature is displayed in three dimensions. The results demonstrate that the skin-friction coefficient rises with growing magnetic numbers, whereas the Casson and the local Williamson parameters show reverse manners.
Originality/value
Moreover, the usefulness and precision of the presented approach are pleasing, as can be seen by comparing the results with previous research. Also, the calculated solutions utilizing the provided procedure were physically sufficient and precise.

Abstract
Purpose
Faculty play a unique role in universities performing duties along the three fronts of teaching, research and service. While it might be teaching that contributes most to the bottom line of a small university, it is often research by which faculty merit is judged. This study explores the relationships between role ambiguity, role conflict and commitment (affective, normative and continuance) as mediated by job satisfaction among faculty members.
Design/methodology/approach
A sample of 133 faculty members at a US-accredited university in Lebanon served as the basis for this study. The faculty members completed a survey covering scales on role ambiguity, role conflict, commitment and job satisfaction in addition to demographic variables.
Findings
We find that a decrease in role ambiguity strengthens affective and normative commitment but weakens continuance commitment. Structural equation modeling indicates that job satisfaction partially mediates the relationship between role ambiguity and affective commitment, while not mediating the relationship between role ambiguity and normative and continuance commitments. Similar findings hold for job satisfaction as a mediator in the relationship between role conflict and commitment.
Originality/value
Based on statistical modeling, this work (1) puts forth a revised scale for organizational commitment tailored to academia and (2) provides guidance to higher education institutions in terms of the differential impacts on faculty commitment that stem from reducing role-ambiguity versus role-conflict. Managerial recommendations focus on improving normative and affective commitment through the design of policies to reduce role conflict among faculty.

Abstract
Purpose
Social initiatives must disclose their results to access support. However, there is no theoretical consensus about how to do it. It is still necessary to understand the value creation in social initiatives because they may or not have economic goals. However, these goals serve to make the social ones feasible. This study aims to cut this Gordian knot by providing measures aligned to the value theory but developed by the social lens. It offers a non-economic-focused approach to dealing with assessment complexity and with multiple stakeholders’ needs for information.
Design/methodology/approach
A consolidation research path is suggested by three composed measures built upon tested and reliable scales. These value measures are discussed through narratives from Portuguese investors and social entrepreneurs in a mixed-methods design. Content analysis and online survey provided data for descriptive statistics, exploratory factor analysis and Cronbach's alpha test.
Findings
The analyses supported the value measures. Thus, they allow an effective way to assess and report the social value created. It also highlighted a potential use in preventive and corrective approaches helpful for several organizations that pursue social goals.
Research limitations/implications
The measures were tested based on social entrepreneurs' opinions. Future studies can include beneficiaries' opinions, allowing comparisons that can help to set more realistic goals and better investment criteria.
Originality/value
The relationship between investors and initiatives can improve, boosting their impact on society. The measures can highlight prioritization choices that influence the way value is created. Hence, they serve as a sensemaking from a holistic standpoint.

Abstract
Purpose
Building on the conservation of resources theory, this research explored the processes underlying the association between perceived workplace incivility and deviant behaviors. Specifically, we tested a mediating mechanism, an interpersonal conflict that has received less consideration in the workplace incivility literature. The authors also tested the organizational climate (i.e. a resource) as a moderator in the perceived workplace incivility–employees’ deviant work behavior relationship.
Design/methodology/approach
Time-lagged research design was followed to explain the relationship of variables. Survey data were collected at time 1 and time 2 from 220 service sector working professionals to test the proposed model.
Findings
The findings suggest that intrapersonal conflict partially mediates the workplace incivility–deviant work behavior relationship. Further, the authors found that the harmful effects of workplace incivility on employees’ deviant work behavior attenuate in the presence of organizational climate as a resource. The results shed light on the beneficial consequences of organizational climate on employees’ work behavior by attenuating workplace incivility and mitigating their deviant work behaviors.
Originality/value
Overall, the study contributed to understanding the mediating role of interpersonal conflict and the moderating role of organizational climate in explaining the workplace incivility–deviant work behavior relationship.

Abstract
Purpose
This study aims to investigate the various systems in logistics industry of Pakistan through the lens of the World Bank's logistics performance indicators (LPI) and understand their impact on the China–Pakistan economic corridor (CPEC) that is a vital part of China's belt and road initiative (BRI).
Design/methodology/approach
In this study thematic analysis was performed on twenty-three semi-structured interviews with experts in Pakistan's logistics and supply chain sector to gain an in-depth insight into the logistics performance relative to CPEC.
Findings
A performance gap exists in the logistics systems in Pakistan, both for hard and soft infrastructure. The significant challenges are the inefficiencies of the government, minimal use of information and computing technology (ICT), and an incapable workforce. It is essential to be cognizant of the ground realities and amendments required in the existing policies and practices in light of the challenges faced and best practices adopted by developed and developing countries with good standing in logistics performance. This study will guide policymakers and practitioners for hard and soft logistics infrastructure improvement, which may benefit economic corridors in general and CPEC in particular.
Originality/value
This study contributes to the existing literature by highlighting the role of ICT in improving both soft and hard logistics infrastructure, which can lead to significant development of economic corridors. The study makes use of a case study of the CPEC to demonstrate the lack of ICT can hamper the growth of an economic corridor despite billions of dollars of investment in the hard infrastructure development projects.

Abstract
Purpose
This paper aims to examine whether family business groups’ (FBG) having the same network auditor among their affiliates mitigates earnings manipulation (EM).
Design/methodology/approach
This paper used unbalanced panel data from the years 2010–2019. The sample of the study is composed of 327 nonfinancial listed Pakistan Stock Exchange firms, consisting of 187 FBG-affiliated firms and 140 nonaffiliated firms. The ordinary least square and generalized least square regressions have been used to check the hypothesized relationship. Furthermore, the propensity score matching technique is used to ascertain comparable companies’ features and to control the potential endogeneity problem. Finally, the results are robust to various measures of EM and FBG’ proxies.
Findings
The findings of the study show that the same network auditor is reducing EM in FBG affiliates. In addition, the BIG4 same network auditors are also instrumental in constraining EM as compared to non-BIG4 audit firms. Overall, the results of this study depict that the same network auditor in FBG’s affiliated firms significantly influences EM. These results are robust with respect to generalized least squares and the endogeneity problem.
Research limitations/implications
This research study has two important implications for the interested parties. First, although the authors find in this research study that the same network auditor is negatively associated with EM in the FBG-affiliated firms, however, FBG-affiliated firms might use opportunistically the real activity manipulation. Second, regulators highlight the change in audit partner/firm rotation, though the study findings indicate that regulators and practitioners may consider the benefits associated with the same network auditors for FBG.
Originality/value
This research study adds a new investigation to previous literature by examining the role of the same network auditors in the EM of the FBG’ affiliates. To the best of the author’s knowledge, this is the first study to bring new knowledge by investigating the role played by the same network auditors along with the BIG4 same network audit firms in constraining EM in FBG.

Abstract
Purpose
This study presents a comprehensive investigation of turnover intention within the context of higher education, specifically focusing on private universities in Egypt, to develop a robust conceptual framework to explore this phenomenon.
Design/methodology/approach
The study sample comprised both male and female tenured faculty members from private universities, and data were collected through questionnaires, resulting in 396 completed responses. Statistical analysis was conducted using SPSS and partial least squares structural equation modeling (PLS-SEM) software.
Findings
The study highlights the significant impact of work-life balance (WLB) and organizational commitment on turnover intention, with job satisfaction as a mediating factor. Additionally, the research reveals that emotional intelligence (EI) does not directly influence turnover intention, but its effects are fully mediated by job satisfaction.
Originality/value
This research not only advances the theoretical understanding of why academics contemplate leaving their positions but also underscores the significance of this topic. Moreover, by exploring turnover intention in the private education sector of the Middle East, the study addresses a notable gap in the existing literature.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
Given the important role of change capability for organizational development and competitive advantage, the purpose of this study is to clarify the influences of transformational leadership (TL) on organizational change capability (OCC) via mediating roles of two specific aspects of trust in leadership namely disclosure-based trust and reliance-based trust.
Design/methodology/approach
Structural equation modeling is applied to test the degree of influences of TL and employee trust on OCC via empirical data collected from 376 participants in 115 small and medium firms in China.
Findings
The results show the positive and significant impacts of TL and aspects of employee trust in leadership on OCC. It indicated that disclosure-based trust in leadership has a greater influence on change capability in comparison with the effect of reliance-based trust in leadership. Especially, the findings have shown the evidence supporting the mediating mechanism of aspects of employee trust in leadership between TL and OCC.
Research limitations/implications
This study provides the practical initiatives that highlight the importance of applying TL style to build and improve the trust of employees in their leadership for fostering OCC.
Originality/value
The paper has significantly advanced and deepened insight of how transformational leaders nurture employee’s specific shades of trust in leadership for fostering OCC. The valuable findings of this study contribute to enriching the theoretical basis of organizational behavior and change management, and can be used to analyze and explain the relationships between TL, employee’s trust in leadership and organizational capability for change.
