Abstract
Purpose
The heat transport phenomenon in which energy transfers due to temperature differences is an important topic of interest for scientists in recent times. It is because of its wide range of applications in numerous domains such as electronics, heat dispersion, thermoregulation, cooling mechanism, the managing temperature in automotive mobile engines, climate engineering, magnetoresistance devices, etc. On account of such considerations, the magnetohydrodynamic (MHD) entropy rate for nanomaterial (CoFe2O4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is analyzed. The Darcy–Forchheimer relation is utilized to describe the impact of a porous medium on a stretched sheet. Two nanoparticles molybdenum (MoS4) and cobalt ferrite (CoFe2O4) are combined to make hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2). Heat flux corresponds to the Cattaneo–Christov model executed through heat transfer analysis. The influence of dissipation and heat absorption/generation on energy expression for nanomaterial (CoFe2O4+MoS4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is described.
Design/methodology/approach
Nonlinear partial differential expressions have been exchanged into dimensionless ordinary differential expressions using relevant transformations. Newton’s built-in shooting method is employed to achieve the required results.
Findings
Concepts of fluid flow, energy transport and entropy optimization are discussed. Computational analysis of local skin friction and Nusselt number against sundry parameters for nanomaterial (CoFe2O4/C2H6O2) and hybrid nanomaterial (CoFe2O4+MoS4/C2H6O2) is engrossed. Larger magnetic field parameters decay fluid flow and entropy generation, while an opposite behavior is observed for temperature. Variation in magnetic field variables and volume fractions causes the resistive force to boost up. Intensification in entropy generation can be seen for higher porosity parameters, whereas a reverse trend follows for fluid flow. Heat and local Nusselt numbers rise with an increase in thermal relaxation time parameters.
Originality/value
No such work is yet published in the literature.

Abstract
Purpose
This study aims to investigate the relationship between committee diversity and firm performance among non-financial firms listed on the Pakistan Stock Exchange (PSX).
Design/methodology/approach
This research is based on a comprehensive assessment of secondary data retrieved from annual reports of firms listed on the PSX and publications from the State Bank of Pakistan spanning the period from 2012 to 2021. The study used various statistical models, including pooled regression, fixed effects and random effects, to examine the relationship between diversity among committees and firm performance. Firm-specific variables such as return on assets, return on equity and market price per share were used as proxies for firm performance.
Findings
The results show that the presence of a female head of the committee on company performance does not show any significant correlation with diversity in board committees. This suggests that the investigation into gender diversity and the appointment of women to leadership positions on these committees is not supported by the findings of this particular sample.
Originality/value
To the best of the authors’ knowledge, this study is the first to investigate the impact of committee diversity on firm performance in Pakistan, one of the Next Eleven countries.

Abstract
Purpose
Learning capability improves knowledge resources fosters innovative capabilities and firm competitiveness. The study aims to examine the human resource management (HRM) practice and employee creativity relationship using organizational learning capability (OLC) as a mediating variable.
Design/methodology/approach
Data were collected from 67 small-sized and 96 medium-sized firms. Confirmatory factor analysis was applied to establish construct validity and reliability. Structural equation modeling was used to evaluate the proposed model and hypotheses.
Findings
The results show that performance appraisal and employee creativity were positively related. Employee participation and employee creativity were positively related. Compensation and employee creativity were nonsignificantly related. OLC mediates the performance appraisal and employee creativity relationship. Similarly, OLC mediates the employee participation and employee creativity relationship. However, OLC did not mediate the compensation and employee creativity relationship.
Research limitations/implications
Due to the research’s SME focus and cross-sectional data, the finding’s generalizability will be constrained.
Practical implications
The findings of the study would be useful to policymakers, stakeholders and management of SMEs in developing a supportive learning climate that promotes experiential and continuous learning cultures to ensure strategic capabilities, sustainable competitive advantage and innovativeness.
Originality/value
The study contributes to the extant literature on OLC, HRM practices and employee creativity by empirically evidencing that OLC mediates the performance appraisal, employee participation and employee creativity relationship.

Abstract
Purpose
This aims to explore the relationship between the agile methods barriers in large-scale contexts and the benefits for business, team and product and process, exploring the organizational readiness (OR) mediating role.
Design/methodology/approach
We propose a theoretical model through survey-based research, applying partial least square structural equation modelling.
Findings
We confirmed that OR mediating effect on the relationship between agile methods barriers and team benefits. We operationalized OR in a broader context that embeds the strategic alignment of large-scale agile implementation, considering variables such as organizational structure and culture.
Research limitations/implications
The data are cross-sectional rather than longitudinal, which limits temporal interpretations of the associations between agile methods and organizational issues.
Practical implications
The findings offer a way forward for organizations already using or planning to implement agile management to understand the pathway towards achieving the expected benefits. Our study also unveils the importance of looking at OR when implementing such a complex change in management from traditional to large-scale contexts.
Originality/value
Our results show the significant and positive influence of agile method on all three benefit variables (team, business, product and processes). Furthermore, we identified the significant and positive mediating role of OR on the relationship between agile method and team benefits.

Abstract
Purpose
This study aims to investigate the effect of high-performance HR practices (HPHRP) on the innovative work behaviour (IWB) of employees. Drawing on social exchange theory, when employees perceive their exchange relationship in terms of HPHRP and leadership support as fair, we hypothesize that employees will demonstrate greater IWB. However, drawing on social identity theory, we hypothesize that when the attitude of employees towards their employer with best employer practices is favourable, the impact of HPHRP mediated by organizational pride and organizational identification, has a greater impact on employee IWB.
Design/methodology/approach
Survey research was used to empirically validate the study involving employees (n = 370) who belong to the best employer brands in India. The data was analysed using Process Macro Models 7 for moderated mediation and Model 6 for serial mediation using bootstrapping procedures.
Findings
The results suggest that perceived leadership support moderated the indirect effect of HPHRP on IWB through organizational pride. Again, organizational pride and identification partially and serially mediated the impact of HPHRP on IWB.
Research limitations/implications
Organizations must invest in HPHRP, with supportive leadership practices that can foster an emotional attitude of pride and a cognitive attitude of organizational identification to be an employer of choice resulting in employees’ IWB.
Originality/value
The study investigating the mediating impact of the emotional and cognitive attitudes of pride and organizational identification has not been previously explored, in the relationship between HPHRP and IWB, from a social identity perspective.

Abstract
Purpose
This study aims to examine the impact of smart talent management (STM) on the performance of small and medium-sized enterprises (SMEs), which is mediated by providing an adoption innovation climate, and to verify the moderate power of adoption motivational culture on STM and SMEs performance (SMEsP).
Design/methodology/approach
The quantitative methodology was adopted through an online survey questionnaire to collect data from SMEs listed in Chambers of Commerce and Industry located in Jordan, the United Arab of Emirates and Kind Saudi Arabia in the Middle East region. Responses were collected from 163 firms out of 568, representing a 28.7% response rate. The data were analyzed using the structural equation modeling technique to test the hypotheses.
Findings
The results of this study fail to support the view that STM has a positive and significant effect on SMEs’ performance, as well as the adoption of motivational culture strengthened the relationship between STM and SMEsP. In addition, the adoption of motivational culture strengthened the relationship between STM and SMEs’ performance.
Originality/value
This research extends the application of cognitive social theory, whereby STM functions as a value-adding activity within SMEs. This research extends the application of cognitive social theory, where STM functions as a value-adding activity within SMEs.

Abstract
Purpose
Social value creation (SVC) is the primary emphasis for unifying the various issues in contemporary social entrepreneurship (SE) literature and practice since it highlights the fundamental problem of sustainability in SE business. Accordingly, SVC as an outcome of SE represents the primary drive of social entrepreneurs (SEs). However, SEs encounter multi-dimensional challenges as they work to build their SE businesses and create social value. In the current context of digitally transforming entrepreneurship scenario, this study investigates the role of SE compassion and digital learning orientation (DLO) for SVC ability of SEs.
Design/methodology/approach
The study utilized a quantitative survey approach for primary data collection from social entrepreneurs in Saudi Arabia. A total of 158 valid replies from social entrepreneurs were obtained for the study. Using SmartPLS (3.0), partial least square structural equation modeling was used to analyze the data.
Findings
The results validated a model of SVC in which the SE compassion and DLO positively impact the SVC ability in SEs. However, the impact of DLO in moderating the SE compassion - SVC relationship in SEs was not proven.
Practical implications
The study established the role of SE compassion in explaining the distinctive SVC ability in SEs. Meanwhile, given the expanding necessity for SEs to leverage digital technologies for SE missions, the study provides implications for nurturing positive outcomes in terms of SE compassion and DLO outcomes among SEs. This organized knowledge can help entrepreneurs, educators and policymakers better incorporate these concerns in SE education, and social enterprises and entrepreneurs’ developmental initiatives.
Originality/value
This work is pioneering in that it conceptualizes and tests a theoretical framework that links SE compassion, DLO, and SVC in SEs. Meanwhile, the study is the first to operationalize the DLO in entrepreneurs. The study thus generates fresh insights about SVC in SE amid the digitally transforming entrepreneurship scenario.
