The aim of this work is to analyze the combined effects of melting, thermal-diffusion and diffusion-thermo on the flow of non-Newtonian fluid.

An efficient approach namely homotopy analysis method is applied to compute the solution of the non-linear problem. Moreover, numerical results using MATLAB function bvp4c are also computed.

Main findings are an increase in the melting process corresponding to increase in the velocity and the boundary layer thickness. However, surface heat and mass transfer decrease by increasing the values of melting parameter M.

Combined effects of thermal-diffusion and diffusion-thermo are analyzed and the solutions are computed both numerically and analytically. Some deduced results can be obtained in a limiting sense.

Drawing on affective events theory, the authors investigated whether exposure to abusive supervision triggers malevolent creativity among victims and the role of psychological contract violation (PCV) as a mediator in this relationship. The authors also examined the moderating effects of the Light Triad personality traits comprising Kantianism, humanism and faith in humanity.

The sample comprised 297 junior doctors working at various clinical departments of public sector hospitals in three major cities of Pakistan. Data were collected using a self-administered questionnaire and the hypothesized model was tested using the covariance-based structural equation modeling in Mplus.

Results demonstrated that abusive supervision influences malevolent creativity directly and indirectly mediated through PCV. Further, results showed that individuals high on the Light Triad traits are less likely to engage in malevolently creative acts in response to abusive supervision and feelings of violation than those low on the Light Triad.

The authors contribute to the literature by demonstrating that exposure to abusive supervision influences the generation of malevolently creative ideas among subordinates. Further, the authors showed that subordinates high on the Light Triad handle abusive supervisory behaviors and negative emotional reactions more productively and are less likely to retaliate against perceived mistreatment compared to their counterparts.

The purpose of the review is to synthesize the research on materiality measures of sustainability reporting and highlight how preparers, users, auditors, regulators and other stakeholders assess or determine the materiality in sustainability reporting. The review further summarizes the findings on consequences and determinants of material disclosures in sustainability reporting. Several directions for future research are also discussed.

This study provides a systematic review of materiality measures developed in the context of sustainability reporting. This synthesis of the literature summarizes the existing methodologies of measuring materiality. It also evaluates the strength and limitations of existing methods and approaches of measuring materiality in sustainability disclosures.

We find that the ex post materiality measures are simplistic and unidirectional in nature and ex ante materiality measures lack external validity and are generally narrow in focus – for example, focused on single firms or industries. Another major limitation in the current literature is the absence of robust empirical investigation of double materiality in sustainability reporting and a vast majority of the measures are developed without stakeholder engagement. Lastly, we document that the findings on determinants of material disclosure are fragmented and inconclusive and that the literature on consequences of material disclosure is rather un-explored.

The study explains the connections and differences between the various materiality measures. We document that materiality is measured in two distinct ways, ex ante and ex post and often times without stakeholder engagement. Moreover, given that a vast majority of the measures rely on manual content analysis, we find that they suffer from reproducibility and scalability.

This chapter explores the strategic integration of Industry 4.0 technologies within the SA8000 audit framework, which marks a transformative shift in ethical and socially responsible practices. Released by Social Accountability International (SAI), SA8000 is a social accountability standard highly relevant in addressing labor-related issues, exerting a pivotal influence on the management of companies and supply chain sustainability. By illustrating how technology can significantly enhance efficiency, transparency, and efficacy in conducting SA8000 audits, data analytics, IoT devices, AI, and blockchain will be used in this chapter. The chapter's recommendations for managers, auditors, and employees point toward strategic management of resources, collaborative activities across different departments, and improving digital competencies. The discussion makes out a clear pathway for the effective application of Industry 4.0 in the SA8000 auditing practices, enhancing sustainability, ethics, and streamlined auditing practices that would significantly contribute to the comprehensive goals of corporate sustainability and social responsibility in today's digital era.

The purpose of the present study is to explore a three-dimensional rotating flow of water-based nanofluids caused by an infinite rotating disk.

Mathematical formulation is performed using the well-known Buongiorno model which accounts for the combined influence of Brownian motion and thermophoresis. The recently suggested condition of passively controlled wall nanoparticle volume fraction has been adopted.

The results reveal that temperature decreases with an increase in thermophoresis parameter, whereas it is negligibly affected with a variation in the Brownian motion parameter. Axial velocity is negative because of the downward flow in the vertical direction.

Two- and three-dimensional streamlines are also sketched and discussed. The computations are found to be in very good agreement with the those of existing studies in the literature for pure fluid.

The purpose of this paper is to investigate non-linear radiation heat transfer problem for stagnation-point flow of non-Newtonian fluid obeying the power-law model. Power-law fluids of both shear-thinning and shear-thickening nature have been considered.

Boundary layer equations are non-dimensionalized and then solved for the numerical solutions by fourth-fifth order Runge-Kutta integration based shooting technique.

The results reveal an existence of point of inflection for the temperature distribution for sufficiently large wall to ambient temperature ratio. Moreover temperature increases and heat transfer from the plate decreases with an increase in the radiation parameter. Heat transfer rate at the sheet is bigger in dilatant (shear-thickening) fluids when compared with the pseudoplastic (shear-thinning) fluids.

Different from the linear radiation heat transfer problem (which can be simply reduced to rescaling of Prandtl number by a factor containing the radiation parameter), here the energy equation is strongly non-linear and it involves an additional temperature ratio parameter _w=T _w/T _∞. This parameter allows studying the thermal characteristics for small/large temperature differences in the flow.
