This study aims to explore entropy evaluation in the bi-directional flow of Casson hybrid nanofluids within a stagnated domain, a topic of significant importance for optimizing thermal systems. The aim is to investigate the behavior of unsteady, magnetized and laminar flow using a parametric model based on the thermo-physical properties of alumina and copper nanoparticles.

The research uses boundary layer approximations and the Keller-box method to solve the derived ordinary differential equations, ensuring numerical accuracy through convergence and stability analysis. A comparison benchmark has been used to authenticate the accuracy of the numerical outcomes.

Results indicate that increasing the Casson fluid parameter (ranging from 0.1 to 1.0) reduces velocity, the Bejan number decreases with higher bidirectional flow parameter (ranging from 0.1 to 0.9) and the Nusselt number increases with higher nanoparticle concentrations (ranging from 1% to 4%).

This study has limitations, including the assumption of laminar flow and the neglect of possible turbulent effects, which could be significant in practical applications.

The findings offer insights for optimizing thermal management systems, particularly in industries where precise control of heat transfer is crucial. The Keller-box simulation method proves to be effective in accurately predicting the behavior of such complex systems, and the entropy evaluation aids in assessing thermodynamic irreversibilities, which can enhance the efficiency of engineering designs.

These findings provide valuable insights into the thermal management of hybrid nanofluid systems, marking a novel contribution to the field.

This study aims to explore the nuanced role of organizational “collectives” in transmitting the effect of high-performance work systems (HPWS) on organizations’ market success and workforce retention.

The multi-source data was collected from 113 construction firms operating in Pakistan using a survey questionnaire.

The findings indicate that collective human capital and collective satisfaction of organizations differentially mediate the effect of HPWS on market success and workforce retention. Collective satisfaction mediates the effect of HPWS on both market success and workforce retention, however collective human capital only mediates this relationship for market success of organizations.

Organizations should consider prioritizing investment in cognitive and affective development of overall human resources. Knowledge, skills, abilities and emotions of individual employees operate at the collective level so organizations should design HRM practices to manage collective thoughts and interpretations.

This is the first study to investigate human capital and satisfaction at the collective organization level to explore collective developmental and motivational paths for HPWS to boost organization strategic outcomes.
