The purpose of this paper is to examine the impact of Chinese listed family firms on lean innovation strategies. Additionally, the authors also examined the moderating role of CEO compensation on the family ownership and lean innovation strategies relationship.

Data is obtained from CSMAR database about Chinese family firms listed at Shenzhen Stock Exchange and Shanghai Stock Exchange. Panel data comprising of firm year observations from 2007 to 2016 is analyzed using STATA.

Family firms are proactive towards research and development investment (innovation input) as well as towards patent applications (innovation output). Moreover, family firms show propensity towards patent applications and towards converting their R&D investment into granted patent applications. CEO compensation negatively moderates the nexus between family firms and lean innovation which seriously needs to be addressed to reduce agency costs.

The study has focused on Chinese market only. The study is useful for policy makers to address the serious concerns identified in the conclusion section, i.e. effectiveness of CEO compensation in addressing the lean innovation strategies in emerging economy like that of China.

Given the usually considered conservative approach of family firms towards innovation, this is the first study which has tested the moderating role of CEO compensation on family firms and lean innovation relationship in an emerging economy. This study is unique because it provides a detailed analysis of lean innovation process by splitting the process into different stages. The negative moderating impact of CEO compensation raises new concerns to resolve agency conflicts.

The purpose of this paper is to present a novel model on the unsteady MHD flow of heat transfer in carbon nanotubes with variable viscosity over a shrinking surface.

The temperature-dependent viscosity makes the proposed model non-linear and coupled. Consequently, the resulting non-linear partial differential equations are first reformed into set of ordinary differential equations through appropriate transformations and boundary layer approximation and are then solved numerically by the Keller box method.

Graphical and numerical results are executed keeping temperature-dependent viscosity of nanofluid. It is noted that, for diverse critical points, it is found that at one side of these critical values, multiple solutions exist; on the other side, no solution exists. A comparison is also computed for the special case of existing study. The temperature and pressure profiles are also plotted for various effective parameters.

The presence and progression of stenosis disturb the normal circulation of blood through an artery and cause serious consequences. The proposed investigation is aimed to assess non-Newtonian characteristics of blood in an elliptical artery having stenosis. The blood is taken as Sutterby fluid flowing via a multi-stenosed elliptical cross-section artery.

The analytical solution of a mathematical model representing the considered problem is extracted in a non-dimensional form by utilizing the perturbation technique under the mild stenosis assumptions.

The graphical nature of these results is examined and discussed comprehensively for different physical parameters. The height and shape of stenosis are noted to have prominent effects on flow velocity. The wall shear stress and flow velocity attained high values in the stenotic portion of the artery. The non-uniform stenosis is observed to create higher resistance to the flow than the uniform stenosis. Further, a high disorder is noticed in the constricted region of the artery by streamlines analysis.

The manuscript completely comprehends the blood’s non-Newtonian flow in the arteries of elliptical shape having multiple stenoses. The present study is about the properties of non-Newtonian blood flow through an elliptical artery with many stenoses. The Sutterby fluid model is used to describe the blood’s non-Newtonian nature. By utilizing presumptions of mild stenosis, the mathematical model’s non-linearity is decreased, and the perturbation method is applied to generate the resulting equations.

The presence of stenosis can significantly impact the circulation of blood flow. When an artery becomes narrowed, it can create a constriction or obstruction in the flow path of blood, which can lead to several important fluid dynamics phenomena, i.e. increased velocity, shear stress, pressure drop, etc. The presence of stenosis can cause various damages and complications in the affected blood arteries and surrounding tissues, resulting in heart attacks or diseases like atherosclerosis.

The work presented in the manuscript was not published earlier in any form.

This paper aims to focus on the natural convective flow analysis of micropolar nanofluid fluid in a rectangular vertical container. A heated source is placed in the lower wall to generate the internal flow. In further assumptions, the left/right wall are kept cool, while the upper and lower remaining portions are insulated. Free convection prevails in the regime because of thermal difference in-between the lower warmer and upper colder region.

The physical setup owns mathematical framework in-terms of non-linear partial differential equations. For the solution purpose of the differential system, finite volume method is adopted. The interesting features of the flow along with thermal transportation involve both translational and rotational movement of fluid particles.

Performing the simulations towards flow controlling variables the outputs are put together in contour maps and line graphs. It is indicated that the variations in flow profile mass concentration and temperature field augments at higher Rayleigh parameter because of stronger buoyancy effects. Higher viscosity coefficient implies decrease in flow and thermal transportation. Further, the average heat transfer rate also grows by increasing both the Rayleigh parameter and heated source length.

To the best of the authors’ knowledge, no such study has been addressed yet. Further, the results are validated by comparing with previously published work.

Based on the theory of crossover, the purpose of this paper is to explore the limited but growing body of research on positive crossover, wherein the authors investigated the direct and indirect crossover of work passion between the dyadic setting of leader and followers. The authors hypothesized that the leader’s (follower’s) work passion influence follower’s (leader’s) work passion through direct crossover phenomena (i.e. crossover via empathy). In the study, the authors also examined the underlying indirect crossover mechanism of leader’s (follower’s) work passion via personal identification – the process by which individuals (supervisors and subordinates) realize cognitive overlap between the self and other over time in a relationship. In an attempt to fully understand the crossover of leader’s (follower’s) work passion, the authors scrutinized the pattern of leader–follower relationship quality, which has the capacity to moderate the direct and indirect crossover of work passion from leader to follower and vice versa.

The authors conducted two independent studies and collected a time-lagged data from the dyadic settings of a large trade multinational company (n=77 supervisor and 373 subordinates) and a large manufacturing multinational company (n=89 supervisor and 411 subordinates) situated in Anhui province of China to test the authors’ moderated mediation model of work passion.

As expected the authors found support for all the authors’ hypothesized relationships. Specifically, the results provide support for the notion of direct and indirect crossover of work passion within leader–follower dyads. Moreover, the authors’ findings also support the moderated mediation model of direct and indirect crossover of work passion.

Overall, this study provides a potential way to stimulate work passion in employees (leader and followers) from the perspective of their relationship quality with each other. Moreover, implications for theory, research and practice with prospective future research topics are discussed.

Based on revenge theory and the three objectives of social interaction theory of aggression, the purpose of this paper is to develop a framework to answer why and when a subordinate’s own behaviour instigates abuse at the workplace. In particular, the authors argue that subordinate gossip behaviour instils in supervisors a thought of revenge towards that subordinate, which, in turn, leads to abusive supervision. Specifically, this hypothesised relationship is augmented when the supervisor feels close to the gossiper (i.e. psychological proximity).

The authors conducted two independent studies to test the moderated mediation model, which collectively investigate why and when subordinate gossip behaviour provokes abusive supervision in the workplace. A lagged study (i.e. Study 1: 422 supervisors and subordinates) in a large retail company and an experience sampling study (i.e. Study 2: 96 supervisors and subordinates with 480 daily surveys) in multiple organisations provide support for the moderated mediation model.

The two-study (i.e. a lagged study and an experience sampling study) findings support the integrated model, which has mainly focussed on instrumental consideration of abusive supervision that influences the supervisor–subordinate relationship.

The two-study investigation has important and meaningful implications for abusive supervision research because it determines that subordinate gossip behaviour is more threating to a supervisor when the subordinate and the supervisor are psychological close to each other than when they are not. That is because when they are close, the supervisor is not expecting gossip behaviour from the subordinate, thus giving rise to an abusive workplace.

The purpose of this paper is to study the effects of temperature‐dependent viscosity on the peristaltic flow of Jeffrey fluid through the gap between two coaxial horizontal tubes.

The inner tube is maintained at a temperature T₀0 and the outer tube has sinusoidal wave travelling down its wall and it is exposed to temperature T₁. The governing problem is simplified using longwave length and low Reynold number approximations. Regular perturbation in terms of small viscosity parameter is used to obtain the expressions for the temperature and velocity for Reynold' s models of viscosity. The numerical solution of the problem has also been computed by shooting method and an agreement of numerical solutions and analytical solutions had been presented. The expressions for pressure rise and friction force are calculated numerically.

Graphical results and trapping phenomenon are presented at the end of the paper to see the physical behaviour of different parameters.

The paper is a new and original work on the subject of peristaltic flows and heat transfer in Jeffrey fluid.

The present critical analysis has been performed to explore the steady stagnation point flow of Jeffery fluid toward a stretching surface, in the presence of convective boundary conditions. It is assumed that the fluid strikes the wall obliquely. The governing non-linear partial differential equations for the flow field are converted to ordinary differential equations by using suitable similarity transformations. Optimal homotopy analysis method (OHAM) is operated to deal the resulting ordinary differential equations. OHAM is found to be extremely effective analytical technique to obtain convergent series solutions of highly non-linear differential equations. Graphically, non-dimensional velocities and temperature profile are expressed. Numerical values of skin friction coefficients and heat flux are computed. The comparison of results from this paper with the previous existing literature authorizes the precise accuracy of the OHAM for the limited case. The paper aims to discuss these issues.

This investigation delves into the rationale behind the preferential applicability of the non-Newtonian nanofluid model over alternative frameworks, particularly those incorporating porous medium considerations. The study focuses on analyzing the mass and heat transfer characteristics inherent in the Williamson nanofluid’s non-Newtonian flow over a stretched sheet, accounting for influences such as chemical reactions, viscous dissipation, magnetic field and slip velocity. Emphasis is placed on scenarios where the properties of the Williamson nanofluid, including thermal conductivity and viscosity, exhibit temperature-dependent variations.

Following the use of the OHAM approach, an analytical resolution to the proposed issue is provided. The findings are elucidated through the construction of graphical representations, illustrating the impact of diverse physical parameters on temperature, velocity and concentration profiles.

Remarkably, it is discerned that the magnetic field, viscous dissipation phenomena and slip velocity assumption significantly influence the heat and mass transmission processes. Numerical and theoretical outcomes exhibit a noteworthy level of qualitative concurrence, underscoring the robustness and reliability of the non-Newtonian nanofluid model in capturing the intricacies of the studied phenomena.

Available studies show that no work on the Williamson model is conducted by considering viscous dissipation and the MHD effect past over an exponentially stretched porous sheet. This contribution fills this gap.
