Abstract

Purpose

In recent times, ternary hybrid nanofluid has garnered attention from scientist and researchers due to its improved thermal efficiency. This study aims to delve into the examination of ternary hybrid nanofluid (Al2O3–Cu–TiO2/water), particularly concerning axisymmetric flow over a nonlinearly permeable stretching/shrinking disk. In addition, the investigation of convective boundary conditions and thermal radiation effects is also considered within the context of the described flow problem.

Design/methodology/approach

Mathematical formulations representing this problem are reduced into a set of ordinary differential equations (ODEs) using similarity transformation. The MATLAB boundary value problem solver is then used to solve the obtained set of ODEs. The impact of considered physical parameters such as suction parameter, radiation parameter, nonlinear parameter, nanoparticle volumetric concentration and Biot number on the flow profiles as well as the physical quantities is illustrated in graphical form.

Findings

The findings revealed the thermal flux for the nonlinearly shrinking disk is approximately 1.33%, significantly higher when compared to the linearly shrinking disk. Moreover, the existence of dual solutions attributed to the nonlinear stretching/shrinking disk is unveiled, with the first solution being identified as the stable and reliable solution through temporal stability analysis.

Practical implications

Understanding ternary hybrid nanofluid behavior and flow has applications in engineering, energy systems and materials research. This study may help develop and optimize nanofluid systems like heat exchangers and cooling systems.

Originality/value

The study of flow dynamics across nonlinear stretching/shrinking disk gains less attention compared to linear stretching/shrinking geometries. Many natural and industrial processes involve nonlinear changes in boundary shapes or sizes. Understanding flow dynamics over nonlinear shrinking/stretching disks is therefore essential for applications in various fields such as materials processing, biomedical engineering and environmental sciences. Hence, this study highlights the axisymmetric flow over a nonlinear stretching/shrinking disk using ternary hybrid nanofluid composed of alumina (Al2O3), copper (Cu) and titania (TiO2). Besides, this study tackles a complex problem involving multiple factors such as suction, radiation and convective boundary conditions. Analyzing such complex systems can provide valuable insights into real-world phenomena where multiple factors interact.

Abstract

Purpose

We examine the relationships among leader spirituality, organizational innovativeness, transformational leadership style and project success. Integrating principles of behavioral learning and social learning theories, we argue that spiritual leadership style is positively linked to project success, and this relationship is mediated by transformational leadership. Furthermore, the relationship between leader spirituality and transformational leadership is moderated by organizational innovativeness.

Design/methodology/approach

Data are collected from 180 individuals working in seven large project-based organizations from the telecom sector in Pakistan. The individuals comprise engineers, functional managers, dedicated project managers and individuals who have led and/or worked in project teams. Data are analyzed using variance-based structural equation modeling.

Findings

Results suggest that the relationship between spiritual leadership style and project success is positive and is partially mediated by transformational leadership. Furthermore, organizational innovativeness positively moderates the spiritual leadership and transformational leadership relationship.

Originality/value

Research calls for examining the relationship between leadership styles and project success. We address this call through examining the role of spiritual leadership style (which is rather ignored in project management literature) for project success. Furthermore, we take a novel evolutionary approach of integrating different leadership styles and indicating determinants as well as contingencies to leadership development.

Abstract

Purpose

This study examines how street food affects urban culture, economics and sustainable tourism. It examines how street food stands, as a cultural and economic phenomenon, influence consumer behaviour and local traditions, particularly in Oman’s evolving street food scene.

Design/methodology/approach

Adopting a quantitative research design, this study utilises an integrated model combining the Stimulus-Organism-Response (S-O-R) and Attitude-Social-Influence-Efficacy (ASE) models. This approach facilitates a comprehensive analysis of the factors influencing consumer behaviour towards street food consumption. The methodology includes surveys and structured interviews with consumers and vendors to assess perceptions, attitudes and behaviours linked to street food in Oman.

Findings

The research identifies key sociocultural, economic and marketing factors that significantly influence consumer engagement with street food. It highlights how traditional elements, such as local customs and societal norms, interplay with contemporary marketing strategies to shape consumer preferences and experiences. The findings suggest that street food not only enhances the culinary experience for travellers but also plays a crucial role in the sustainable development of local tourism economies.

Originality/value

This study contributes to the existing literature by providing a novel empirical exploration of street food consumption in Oman, a relatively underexplored area within tourism research. It offers valuable insights into how street food can be leveraged to bolster local economies and enrich the tourist experience through sustainable practices. By integrating the S-O-R and ASE models, this research provides a unique framework for understanding the dynamic relationship between street food culture and consumer behaviour in a Middle Eastern context.

Abstract

Purpose

The study aims to explore the moderation effect of renewable energy consumption (REC) on the relationship between foreign direct investment (FDI) inflows and carbon emission (CO2). Furthermore, the study investigates the prevalence of rebound effect in energy efficiency for the top five FDI inbound destinations in the Asia-Pacific region.

Design/methodology/approach

The study uses a balanced panel data set spanning from 1995 to 2020 obtained from the World Bank Database. This paper used feasible generalized least squares (FGLS) as the primary method, and to ensure the robustness of the findings, this paper used the panels corrected standard errors (PCSE) model.

Findings

The findings reveal a negative relationship between FDI and CO2 emissions and REC and CO2 emissions. However, the moderation effect of REC on the relationship between FDI inflows and CO2 emissions is positive, suggesting that when both FDI and REC increase simultaneously, carbon emissions also increase. This study attributes the observed positive moderation effect to the phenomenon known as the rebound effect.

Research limitations/implications

FDI fosters environmental sustainability. Regions’ FDI policies can be guidelines for other nations aiming for similar outcomes. REC reduces CO2 emissions, underlining renewable energy’s efficacy. However, positive moderation effect of REC on the relationship between FDI and CO2 emissions highlights the necessity for balanced policies to prevent unintended consequences like the rebound effect.

Originality/value

The originality of this study lies in examining the prevalence of rebound effect in energy efficiency. Prior empirical studies have explored the relationship between REC and carbon emission and established that increased efficiency in renewable energy creates positive environmental and climate externalities. However, it is constrained by rebound effects and this has been ignored by previous studies.

Abstract

Purpose

This study advances ethnocentric behaviour research by exploring its impact on individuals' work disengagement in multicultural work settings. Ethnocentrism research focused mainly on consumer ethnocentric behaviour but did not consider the role of employees’ ethnocentric behaviour in the multicultural workplace. This study aims to address this gap by utilizing social identity theory. The authors propose that ethnocentric behaviour has an impact on employee work disengagement and also affects social undermining and workplace conflict as an outcome.

Design/methodology/approach

This study used cross-sectional data (N = 326) collected from employees working for Chinese multinational firms in Bangladesh. The authors used Likert-type scale to collect data. To check the hypothesis, the authors employed Hayes' PROCESS macro 4.0v.

Findings

The authors found that employee ethnocentric behaviour positively impacts workers' work disengagement. Ethnocentric behaviour positively affects social undermining and workplace conflict, whereas social undermining and workplace conflict partially mediate the indirect effects of ethnocentrism on work disengagement. The authors also found that core self-evaluation (CSE) weakens the indirect impact of ethnocentrism on work disengagement through social undermining and workplace conflict.

Practical implications

The authors recommend that organizations recruit employees with positive CSE and provide cultural sensitivity training to reduce ethnocentrism in the culturally diverse workplace.

Originality/value

This study is a unique effort to examine the influence of employees’ ethnocentric conduct by employing social identity theory in the emerging economy subsidiaries of multinational businesses operating in developing countries. This study also addressed the moderating effect of employees' CSE. This adds a unique dimension to ethnocentrism and employee work disengagement research. The authors have also discussed the future research avenue, theoretical and practical implications in detail.

Abstract

Purpose

This study aims to conceive and develop a pricing model for the Ijara contingent convertible contract (ICCC, hereafter), considering the possibility that the lessee may default. The ICCC model grants the lessor the option of converting the unpaid amount into equity or recovering the leased equipment and selling it at market price in case of financial distress.

Design/methodology/approach

The ICCC is consistent with the profit-sharing approach and the new risk management techniques, which are compatible with Islamic philosophy. Relying on real options theory and the contingent claim approach, a closed-form solution of the firm’s assets is developed in a dynamic environment, where the rate of return is generated by a Cox-Ingersoll-Ross stochastic process.

Findings

Examining the numerical analysis reveals the impact of the firm value, the conversion or sell decision and the conversion ratio and volatility on the ICCC value. The value of the ICCC can increase substantially as the value of the firm approaches the conversion threshold. The conversion ratio as well as the asset market price play equally an important role in the decision to convert or sell.

Originality/value

This paper develops a pricing model for a contingent Ijara contract, which incorporates a conversion option to mitigate the lessee’s credit risk during periods of economic instability. The ICCC is a cooperative strategy that would be advantageous to all parties, including the lessor and lessee. In the event of a conversion, businesses may be able to continue operating thanks to this financial innovation, and the lessor may profit from the company’s recovery by freeing up more resources for the use of more profitable ventures.

Abstract

Purpose

By addressing the dearth of literature on the subject of cybersecurity risks and artificial intelligence (AI), this study aims to close a research gap by concentrating on the ever-changing environment of online social networks (OSNs) and technology. The main goals are to classify cyberattacks into categories like malware, phishing/spam and network intrusion detection; to identify efficient algorithms for preventing cyber threats; to review relevant literature from 2019 to 2020; and to use machine learning algorithms to detect suspicious behavior related to malware. The study offers a novel framework that suggests particular machine learning algorithms for every kind of cyber threat, hence improving cybersecurity knowledge and reaction capacities. This makes the research useful for examining the impact of cybersecurity on smart cities.

Design/methodology/approach

Thirty papers have been examined on AI and machine learning algorithms, including K-nearest-neighbor (KNN), convolutional neural networks (CNN) and Random Forest (RF), that were published in 2019 and 2020. Using analytical software (NVivo), a qualitative approach is used to retrieve pertinent data from the chosen research. The researchers divide cyberattacks into three groups: network intrusion detection, phishing/spam and malware.

Findings

The study’s conclusions center on how AI and machine learning algorithms linked to cybersecurity are reviewed in the literature, how cyberattacks are classified and how an inventive framework for identifying and reducing risks is proposed. This makes the research useful for researching the implications of cybersecurity for smart cities.

Practical implications

The practical implications of this research are noteworthy, particularly in the realms of technology, AI, machine learning and innovation. The utilization of the NVivo technique enhances decision-making in uncertain situations, making the study’s results more reliable. The findings showcase the applicability of tools in analyzing malicious cyberattacks to address issues related to social media attacks, emphasizing their practical utility. The study’s relevance is further highlighted by a real-world example, where a Kuwaiti public sector fell victim to a malware attack, underlining the importance of cybersecurity measures aligned with the New Kuwait 2035 strategic development plan. The innovative framework presented in the research guides the selection of algorithms for detecting specific malicious attacks, offering practical insights for securing information technology (IT) infrastructure in Kuwait.

Social implications

The rapid digitization in Kuwait, accelerated by the COVID-19 pandemic, underscores the pivotal role of technology in government services. Ma’murov et al. (2023) emphasize the significance of digitization, particularly in accessing and verifying COVID-19 information. The call for a dedicated digital library for preserving pandemic-related material aligns with the evolving digital landscape. Cybersecurity emerges as a critical concern in Kuwait and the Gulf Cooperation Council (GCC), necessitating transnational cooperation (Nasser Alshabib and Tiago Martins, 2022). In the local context, the inefficiency of information security systems and low awareness among government employees pose cybersecurity challenges (Abdulkareem et al., 2014). Social media’s role during the pandemic highlights its significance, yet the need for cybersecurity in this domain remains underexplored (Ma’murov et al., 2023; Safi et al., 2023).

Originality/value

The unique aspect of the paper is its in-depth investigation of the relationship between cybersecurity and AI in OSNs. It uses a special application of machine learning methods, including CNN, RF and KNN, to identify suspicious behavior patterns linked to malware. The detailed analysis of 30 research papers released between 2019 and 2020, which informs the choice of suitable algorithms for diverse cyber threats, further emphasizes the study’s uniqueness. The novel framework that has been suggested categorizes assaults and suggests certain machine learning techniques for identification, offering a useful instrument to improve comprehension and reactions to a variety of cybersecurity issues.

Abstract

Purpose

This study examines the impact of corporate governance on succession planning and organizational performance. Drawing on agency theory, the main purpose of this study is to identify the effect of corporate governance on succession planning by measuring the different characteristics of the board of directors.

Design/methodology/approach

This multi-quantitative research used primary and archival data. A total of 281 valid questionnaires were collected from Chinese listed family firms to gauge succession planning. Relevant archival data were obtained to measure board characteristics and organizational performance. All hypotheses were examined through structural equation modeling.

Findings

The outcomes indicate that corporate governance positively influences succession planning and, in turn, boosts superior organizational performance, which uncovers the mediating effect of succession planning on the relationship between corporate governance and organizational performance. Our findings reveal that board independence and education facilitate the development of succession planning, which is crucial in the family business’s life cycle.

Originality/value

The results of this study contribute to management succession, strategic management and leadership research by demonstrating how corporate governance fosters organizational performance through succession planning, thereby expanding the application scenarios of agency theory in family firms. Additionally, the article also enriches our understanding of how family businesses apply sound governance structures to promote organizational strategic decision-making during the succession process.

Abstract

Purpose

This study aims to assess the board of directors’ effectiveness in curbing earnings management (EM) in Jordan, a country where Islamic religious values strongly influence corporate practices.

Design/methodology/approach

Using a sample of 51 Amman Stock Exchange-listed firms from 2012 to 2022, generalised least squares regression is used to examine the association between board characteristics and EM.

Findings

Most board characteristics do not significantly affect EM. Interestingly, board activity is significantly and positively associated with EM, suggesting that the board’s monitoring function has been relegated to a secondary role.

Research limitations/implications

Formal corporate governance mechanisms may prove ineffective, as their effectiveness in limiting EM is undermined by informal rules.

Practical implications

Regulators should adapt corporate governance rules to the context in which they are embedded. Greater attention to religious dynamics could improve board oversight effectiveness.

Originality/value

This study provides a new perspective to analyse the relationship between corporate governance and EM. To the best of the authors’ knowledge, this is among the first studies to explore this issue within the context of Islamic countries.
