This paper aims to investigate the influence of smooth curvature distributions on the self-noise of a low Reynolds number aerofoil and to unveil the flow mechanisms in the phenomenon.

In this paper, large Eddy simulation (LES) approach was performed to investigate the unsteady aerodynamic performance of both the original aerofoil E387 and the redesigned aerofoil A7 in a time-dependent study of boundary layer characteristics at Reynolds number 100,000 and angle of attack (AoA) 4-degree. The aerofoil A7 is redesigned from E387 by removing the irregularities in the surface curvature distributions and keeping a nearly identical geometry. Flow vorticity magnitude of both aerofoils, along with the spectra of the vertical fluctuating velocity component and noise level, are analysed to demonstrate the bubble flapping process near the trailing edge (TE) and the vortex shedding phenomenon.

This paper provides quantitative insights about how the flapping process of the laminar separation bubble (LSB) within the boundary layer near the TE affects the aerofoil self-noise. It is found that the aerofoil A7 with smooth curvature distributions presents a 10% smaller LSB compared to the aerofoil E387 at Reynolds number 100,000 and AoA 4-degree. The LES results also suggest that curvature distribution smoothing leads to a 6.5% reduction in overall broadband noise level.

This paper fulfils an identified need to reveal the unknown flow structure and the boundary layer characteristics that resulted in the self-noise reduction phenomenon yielded by curvature distribution smoothing.

Pakistan lies between latitudes 24° 37′ N and longitudes 62° 75′ E, covering a total land area of 796,096km². The country shares its borders with Iran to the west, India in the southeast, Afghanistan in the northwest, and China in the north. The Arabian Sea lies to its south (UNISDR, 2005; Khan, 2004d). The country has four provinces: the Punjab, the North West Frontier Province (NWFP), Sindh, Baluchistan, and two federally administrated territories – the Federally Administered Tribal Areas (FATA) and the Northern Areas. The Northern Areas have been recently given the status of Gilgit-Baltistan province. The structure of the provisional government is still in its formation stage. In addition, the territory of Azad Jammu and Kashmir (AJK) is under the administration of the government of Pakistan. Each province or territory is further divided into administrative units known as districts (GOP, 2003; Khan, 2004d).

This study examines the effects of formal institutional distance (ID) on the foreign subsidiary global mandates (i.e. the subsidiary value-added role in terms of research and development (R&D), product management and supplying of inputs to the multinational enterprise (MNE) globally). Furthermore, it examines the mediating role of subsidiary autonomy for innovation in the relationship between formal ID and subsidiary global mandates.

Survey evidence from foreign subsidiaries in a remote developed economy, i.e. New Zealand, is obtained. Formal distance is measured based on the worldwide governance indicators (WGI), and the hypotheses are tested using structural equation modeling.

Results show that the direct link between formal ID and subsidiary global mandates is negative. However, autonomy for innovation as a mediator offsets this negative relationship, showing a positive mediating effect between formal ID and subsidiary global mandates.

This study extends research on foreign subsidiaries and their value-added roles in the MNE. We show the differentiated role of formal ID and indicate a contingency showing how the negative influence of formal ID on subsidiary global mandates can be offset. The inconsistent mediation of autonomy for innovation suggests that the concept of ID is multifaceted and complex, in contrast to the popular view that ID has only negative implications. Drawing upon evidence from a remote, developed economy and secondary data sources, we suggest how MNEs may positively use their formal ID with their subsidiaries.

The purpose of this study is that researchers have widely explored and associated corporate social responsibility (CSR) with firm success. Measuring the relationship between CSR, service quality, corporate reputation and brand preference by drawing on the stakeholder theory in developing countries remains a substantial research gap.

The data were collected using a survey method. The study was performed on 387 respondents who have undergone treatments in hospitals. The authors analysed the data using the Smart PLS 3.0 structural equation modelling technique.

The survey revealed that service quality and CSR are positively linked with corporate reputation, leading to brand preference in the health-care sector.

The survey was performed in the context of the health-care industry; however, additional studies are necessary to extrapolate the findings to other fields, such as education and food. This research helps guide policymakers, administrators, health-care managers and researchers by highlighting the contribution and role of service quality, CSR and corporate reputation in achieving a hospital’s performance.

This study contributes to the CSR literature by introducing the concept of CSR. To the best of the authors’ knowledge, this study also extends research in the diverse literature by examining the relationship between CSR, service quality, corporate reputation and brand preference by illustrating the stakeholder theory in the context of the health-care sector.

This paper aims to examine the relationships among supplier management practices, organizational context and supplier performance. The contexts selected for supplier management practices are economics transactional practices and high involvement work practices (HIWP); while power asymmetry and competition intensity are considered within the organizational context.

A questionnaire survey was conducted on a multinational semiconductor company. A two‐phase statistical analysis, which comprised phase one (reliability and factor analysis), and phase two (hierarchical multiple regression analysis), was used to analyze the data.

The study provides empirical evidence to support the conceptual and prescriptive statements in the literature regarding the impact of supplier management practices and the dynamics between organizational context and supplier management towards supplier performance. The results show that high involvement work practices (HIWP) mediate the impact of competition intensity on suppliers' quality performance and partially mediate the effect of competition intensity on suppliers' flexibility. The limitation of this study is that it does not use longitudinal data, which would be more useful to examine changes in variables that affect performance; nevertheless, as this study was conducted in‐house, it was able to control the extraneous factors.

The study provides important insights for managers to understand the disposition of the firm to better leverage organizational context by exploiting relationships with suppliers. The paper has extended organizational theory and marketing theory into a supply chain context. Moreover, it is among the first empirical work that specifically investigates the relationship between organizational context and supplier management practices; thus the paper fills an important gap in the supply chain literature.

This study aims to investigate the influence of requirement engineering (RE) on project performance (PP) in the context of NEOM* in Saudi Arabia. The study also aims to examine the relationship between three components of RE, evolving market needs (ECN), market changes (MC) and technological advancements (TA), on PP, through the mediating influence of effective communication (EC), change readiness (CR) and stakeholder engagement (SE). Further, the study aims to examine the moderating effect of team cohesion (TC) on the RE–PP relationships.

A research framework is developed by drawing on the resource-based theory and with the support of empirical evidence and rational arguments to propose a set of hypotheses relating to the constructs in the framework. The hypotheses are tested through survey data collected from individual employees working on different projects across NEOM. A total of 336 useable responses were collected that were analyzed through covariance-based structural equation modeling using AMOS v.28.

The results show although ECN and TA both have a positive impact on PP, MC had no significant relationship with PP. In terms of the mediation hypotheses, EC, CR and SE all partially mediate the relationships between ECN and TA with PP. However, there was no mediating effect in the relationship between MC and PP. Moreover, EC, CR and SE themselves have a significant positive influence on PP. Finally, TC proved to be a significant moderator between ECN and PP and TA and PP, but not in the case of MC and PP.

This study makes three novel contributions. First, most prior empirical studies examined the overall impact of RE on PP; however, the current study provides a more nuanced insight into the relationships between the three components of RE (i.e. ECN, MC and TA) and PP. Second, the mediating roles of EC, CR and SE between components of RE and PP present a finer-grained understanding of how project resources are linked to project success goals through features of the project team. Third, moderating influence of TC with regard to a higher possibility of success for projects are highlighted through this discovery.

Exploitative leadership as a form of destructive leadership may hinder employees' knowledge sharing. However, how and when exploitative leadership impacts employees' knowledge sharing is under explored. Drawing on fairness heuristic theory, this study aims to construct a moderated mediation model to investigate the impacting mechanisms of exploitative leadership on employees' knowledge sharing by introducing organization-based self-esteem as a mediator and perceived organizational procedural justice as a moderator.

To test the research model, data were collected from 148 full-time employees at two-time points and analyzed using partial least square-structural equation modelling (PLS-SEM).

Exploitative leadership has a direct negative impact on knowledge sharing. Through the mediation of organization-based self-esteem, exploitative leadership has an indirect impact on knowledge sharing. Organizational procedural justice can weaken the indirect negative relationship between exploitative leadership and knowledge sharing via organization-based self-esteem.

This study is the first to introduce fairness heuristic theory to explain the relationship between exploitative leadership and knowledge sharing. Findings about the mediating role of organizational self-esteem and the moderating role of organizational procedural justice in the relationship between exploitative leadership and knowledge sharing can uncover the black box of how exploitative leadership affects knowledge sharing.

This study aims to dissect and understand the latent themes of Islamic work ethic (IWE) and explore the driving factors of IWE research.

Structural topic modeling (STM), a sophisticated machine learning technique, was used to analyze a corpus of 205 articles sourced from the Scopus database. These articles cover the 36 years of research on IWE, from 1988 to 2024. Moreover, negative binomial regression was applied to examine the driving factors of IWE research.

The STM analysis unfolds ten topics in conjunction with IWE including individual success, workplace dynamics, organizational work ethics, knowledge management, employee citizenship behavior, financial ethics, job satisfaction, organizational commitment, performance enhancement and leadership. The further STM outputs included word clouds, prevalence proportions, correlation matrix, heatmap, relationship of topics with metadata, topic prominence in the publishing journals and, finally, illustrating trends and future prospects of research on IWE. The results of negative binomial regression reveal that number of authors, article age, journal indexing, authors from multiple countries and number of references are strong drivers of fostering research in IWE, by having significant positive impacts on total citations.

The insights from this study provide valuable guidance for businesses and organizations looking to integrate IWE principles into their operations. By promoting values such as fairness, hard work and ethical behavior, organizations can foster a more inclusive and morally grounded workplace culture. This, in turn, may lead to enhanced employee satisfaction, greater organizational commitment and improved overall performance. Additionally, the emphasis on ethical practices can contribute to broader societal benefits, such as increased trust in business practices and a stronger alignment with social responsibility initiatives.

This is a unique study that explores the latent themes and characteristics of the IWE literature through STM and provides insights on the future research directions. In addition, this study also examines the driving factors of IWE research.
