Abstract

Purpose

To generate electricity, solar photovoltaic (PV) systems are among the best, most eco-friendly and most cost-effective solutions available. Extraction of maximum possible electricity from the solar PV system is complicated by a number of factors brought on by the ever-changing weather conditions under which it must operate. Many conventional and evolutionary algorithm-based maximum power point tracking (MPPT) techniques have the limitation of not being able to extract maximum power under partial shade and rapidly varying irradiance. Hence, the purpose of this paper is to propose a novel hybrid slime mould assisted with perturb and observe (P&O) global MPPT technique (HSMO) for the hybrid bridge link-honey comb (BL-HC) configured PV system to enhance the better maximum power during dynamic and steady state operations within less time.

Design/methodology/approach

In this method, a hybridization of two algorithms is proposed to track the true with faster convergence under PSCs. Initially, the slime mould optimization (SMO) algorithm is initiated for exploration of optimum duty cycles and later P&O algorithm is initiated for exploitation of global duty cycle for the DC–DC converter to operate at GMPP and for fast convergence.

Findings

The effectiveness of the proposed HSMO MPPT is compared with adaptive coefficient particle swarm optimization (ACPSO), flower pollination algorithm and SMO MPPT techniques in terms of tracked GMPP, convergence time/tracking speed and efficacy under six complex partial shading conditions. From the results, it is noticed that the proposed algorithm tracks the true GMPP under most of the shading conditions with less tracking time when compared to other MPPT techniques.

Originality/value

This paper proposes a novel hybrid slime mould assisted with perturb and observe (P&O) global MPPT technique (HSMO) for the hybrid BL-HC configured PV system enhance the better maximum power under partial shading conditions (PSCs). This method operated in two stages as SMO for exploration and P&O for exploitation for faster convergence and to track true GMPP under PSCs. The proposed approach largely improves the performance of the MPP tracking of the PV systems. Initially, the proposed MPPT technique is simulated in MATLAB/Simulink environment. Furthermore, an experimental setup has been designed and implemented. Simulation results obtained are validated through experimental results which prove the viability of the proposed technique for an efficient green energy solution.

This study aims to evaluate sustainable investment policies for housing in Qatar.

Abstract

Purpose

This study aims to evaluate sustainable investment policies for housing in Qatar.

Design/methodology/approach

This paper proposes a new model for analyzing sustainable investment policies for housing demand in Qatar via a hybrid quantum fuzzy decision-making model. The study processed the criteria with the facial expression-based Quantum Spherical fuzzy DEMATEL and ranked the alternatives with the facial expressions-based quantum spherical fuzzy TOPSIS. Four factors were determined due to a comprehensive literature review (Environment, Housing Design, Building Design, and Surrounding the building), with five sustainable investment policy alternatives (Electricity production with renewable energies, Recycling systems and materials in construction, Transport with less carbon emission, Biodiversity for residents, and Resilience to natural disasters).

Findings

The analysis indicates that the design of the building is the most important factor (0.254), while the environment is the most influencing factor (0.253) regarding housing demand in Qatar. Transport with less carbon emission and electricity production with renewable energies are the most critical alternative investment policies.

Originality/value

This study provides useful insights for regulators, policymakers, and stakeholders in Qatar’s sustainable investment policies for housing demand. The main motivation of this study is that there is a need for a novel model to evaluate the sustainable investment policies for housing demand. The main reason is that existing models in the literature are criticized due to some issues. In most of these models, emotions of the experts are not taken into consideration. However, this situation has a negative impact on the appropriateness of the findings. Because of this situation, in this proposed model, facial expressions of the experts are considered. With the help of this issue, uncertainties in the decision-making process can be handled more effectively.

Abstract

Purpose

The study analysed the influence of organizational justice on the duty orientation of employees in the mining sector of Ghana. Also, it examined the mediating role of supervisor-provided resources in the relationship between organizational justice and duty orientation.

Design/methodology/approach

The study obtained data through a self-administered questionnaire from 291 employees of a mining firm. The data were analysed and interpreted in light of the hypotheses using the partial least squares structural equation modelling technique.

Findings

The findings revealed that organizational justice had a significant positive relationship with duty orientation and supervisor-provided resources. The results again established that supervisor-provided resources had a significant positive relationship with duty orientation. The study finally documented that supervisor-provided resources partially mediate the relationship between organizational justice and duty orientation.

Practical implications

We recommended that the management of the mining companies devote resources to developing organizational justice policies based on fairness in resource allocation, clear roles, employee feedback and effective information dissemination. Furthermore, supervisors should place priority on acquiring and dispensing resources as employees demonstrate their willingness to improve duty orientation.

Originality/value

The study contributes to knowledge in a novel research area. It adds to empirical evidence by highlighting the possible variables that may influence employees to engage in duty orientation.

Abstract

Purpose

The purpose of the current exploratory study is to provide a more comprehensive understanding of the essence of impulse buying and postulate the drivers behind it for Azerbaijani consumers who practice Islam. Though there are numerous factors that impact impulsive buyer tendencies, current empirical research focuses on demographic indicators and persona characteristics that influence impulsive buying, which are considered as internal factors.

Design/methodology/approach

The current research is exploratory and uses the quantitative research method. A total of 442 responses were collected from the surveys between April 6th and May 6th, 2022, with random sampling. The collected data was analyzed with the SPSS Statistics software and the SPSS AMOS 26 version. Cronbach’s alpha was calculated to measure the reliability of the scales. The construct validity of the questionnaire was measured with confirmatory factor analysis (CFA). The correlation among variables was measured by calculating the Pearson correlation coefficient. The structural equation model was run to determine the structural relationship between latent variables and test the proposed hypotheses.

Findings

According to the regression weights, all the latent variables, excluding materialism, have a statistically significant impact on the impulsive buying tendency. Hedonic motivation and self-esteem have a positive relationship with hedonic buying tendency, while self-control is inversely related. In terms of the impact of demographic indicators on impulsive buying tendency, for Azerbaijani consumers, impulsive buying behavior, differs based on age, education and marital status. However, contrary to previous research, impulsive buying behavior does not change based on income level. However, based on the squared multiple correlations, the predictive power of the model is 24%.

Research limitations/implications

The current study measured the general impulsive behavior of the local population. Analyzing impulsive buyer behavior toward particular products or product categories might lead to different results. Therefore, other researchers can focus on studying impulsive buyer behavior toward different product categories.

Practical implications

Understanding consumer buyer behavior, including impulsive buyer behavior, is among extensively researched subjects. However, studies examining the state of impulsive buyer behavior in Azerbaijan and, most importantly, measuring the impact of the numerous factors behind it are lacking. The majority of the available empirical research in Azerbaijan analyzes consumer behavior from a different perspective. However, none of them approaches it from the perspective of analyzing and measuring impulsive buying. Hence, understanding the motivations behind impulse buying behavior can benefit both businesses and consumers, though for contrasting reasons. The former can use the data to determine the triggers for impulse buying, while the latter can be more conscious of their purchasing behavior to avoid unfavorable financial consequences. The primary implication for businesses is that they will be equipped with empirical evidence on which factors and to what extent they influence consumer buying behavior. Subsequently, they can use it while developing marketing and customer relationship strategies.

Originality/value

There are countless studies focused on defining and measuring impulsive buyer behavior; however, there is a gap in measuring the impulsive buyer behavior of Muslim consumers and, most importantly, understanding the underlying factors. In addition, empiric research examining the state of impulsive buyer behavior of local Muslim consumers in Azerbaijan and, most importantly, measuring the impact of numerous factors behind it is absent. The majority of the available empirical research in Azerbaijan analyzes consumer behavior from a different perspective. However, none of them approaches it from the perspective of analyzing and measuring impulsive buying. The current study analyzes the impact of consumers’ hedonic motivations, materialist values, ability to retain self-control and psychological state on their impulse buying tendency.

Abstract

Purpose

This study aims to investigate whether integrating environmental, social and governance (ESG) practices mediates the relationship between executive incentive compensation and the financial performance of Islamic and conventional banks in the Middle East and North Africa (MENA) region.

Design/methodology/approach

This study used multiple regression models to analyze the effectiveness of ESG practices as a mediating variable in explaining the relationship between executive incentive compensation and banks’ financial performance between 2015 and 2021. The sample consisted of 57 Islamic and conventional banks operating in the MENA region, and the data were collected from the Thomson Reuters database (Data Stream).

Findings

This research paper showed the positive and significant mediating effect of the ESG practice on Banks’ financial performance. Thus, banks’ financial and stock market profitability is influenced by ESG information disclosure. This finding shows that taking ESG into account improves the relationship between executive incentive compensation and banks’ financial performance.

Practical implications

The results may interest academic researchers, regulators and policymakers and would support stakeholders and decision-makers who wish to discover how executive incentive compensation affects financial performance in banks.

Originality/value

This study contributes to previous literature by studying the mediating effect of ESG practices on the relationship between executive incentive compensation and banks’ financial performance. Indeed, the originality of this research paper is justified by the scarcity of studies and, to the best of the authors’ knowledge, constitutes one of the first attempts to examine this relationship via a mediating variable, i.e. ESG.

Abstract

Purpose

This paper examines the understanding of various factors that influence consumer purchase intentions of renting products as a result of growth in the sharing economy. In addition, the study examines the notion of consumer minimalism, the mediating role of environmental consciousness and the moderating role of consumer scepticism to explain consumer rental consumption intention.

Design/methodology/approach

The research used a survey questionnaire to collect data from Indian consumers (N = 259). Data analysis involved using structural equation modelling with AMOS v25 and PROCESS macro. Structural equation modelling was employed to test the models involving mediation, moderation and moderated mediation.

Findings

The findings link consumer minimalism and the intention to rent products. This research contributed to the existing body of knowledge by incorporating the concepts of consumer minimalism and consumer scepticism into consumers' decisions regarding renting products. Furthermore, the results demonstrated that environmental consciousness enhances consumers' inclination to rent products, shedding light on the factors influencing this preference.

Originality/value

This research extends the existing literature on consumer purchase intentions for rented products by investigating how consumer minimalism, mediated by environmental consciousness and moderated by consumer scepticism, influences these intentions. The results offer valuable insights for both theoretical understanding and practical applications, guiding marketing developers and brands that cater to minimalist consumers interested in renting products. Additionally, it suggests future research avenues in this domain.

Abstract

Purpose

Positive psychology helps us understand the knowledge required to contribute to adolescents' societal development and adjustability. Adolescence is the crucial stage to work on for a balanced personality. The present study concerned adolescents' self-strength, happiness, and help-seeking behaviour. The authors aimed to explore the relationship between adolescents' self-strength and happiness and investigate the mediational effect of adolescents' help-seeking behaviour on their self-strength and happiness.

Design/methodology/approach

The research design of the current quantitative study was correlational, and 809 adolescents from China and Pakistan participated in the present study. Data were personally collected from participants through self-developed scales.

Findings

We deployed Pearson correlation and simple mediation using SPSS software and found a linear, positive, strong (r = 0.654, n = 809, p = 0.000 < 0.01) and statistically significant correlation between adolescents' self-strength and happiness. The authors also found a significant indirect effect of help-seeking on adolescents' self-strength and happiness at (β = 0.373, t(907) = 7.01).

Research limitations/implications

Using self-reported scales to gather information was one of the study's limitations. Adolescents may have misunderstood the notion or construct narrated in words or responded biasedly despite the bilingual scales.

Practical implications

This study offers social and practical implications for educators, parents, and school administrators to address the development of adolescents' personalities using a positive psychology lens.

Originality/value

The findings are of significant importance for teachers working in the elementary schools. They may work on adolescents' self-strength, happiness, and help-seeking to develop balanced personalities.

Abstract

Purpose

The continued relevance of technologies in halal industries requires managers to understand the factors contributing to such technologies’ acceptance. The technology acceptance model (TAM) is dominant in the literature that predicts user acceptance and behaviour towards technology. Despite the model’s significance, there has yet to be a systematic review of studies featuring halal sectors that use TAM. The purpose of this study is to systematically review the existing literature on TAM in halal industries to understand the research trends as well as TAM modifications and research opportunities in halal industries.

Design/methodology/approach

Guided by the preferred reporting items for systematic review and meta-analysis protocol, a framework-based review using the theories, contexts, characteristics and methods (TCCM) framework was conducted. The Scopus and Web of Science databases were used to retrieve English journal articles that investigated TAM in the context of halal markets. In total, 44 eligible articles were reviewed in terms of the developments and extensions of TAM in their studies across the halal industries.

Findings

The first study related to the use of TAM in the context of halal industries was published in 2014. The most prominent halal industry in the review, which used TAM, was Islamic finance. Indonesia was the leading economy in halal studies using TAM. Perceived usefulness was found to be a more significant factor than perceived ease of use for technology acceptance in TAM studies on halal industries. The significance of religiosity on TAM was inconsistent. Most research was done using quantitative surveys with consumers as the target sample.

Research limitations/implications

The studies in this review are based on the Scopus and Web of Science databases, which may be perceived as a study limitation. This study also only considered English journal articles and research in which the focus was on the use of TAM in halal industries rather than general industries with Muslim consumers.

Practical implications

Halal industries will continue to rely on technology for the provision of goods and services. With the rise of emerging technological innovations, this review will provide managers with an appreciation of technology acceptance across different contexts. Researchers can use the results of this review to guide future studies and contribute toward the development of this research area.

Originality/value

This review contributes to the Islamic marketing literature by being the first to comprehensively review the TAM model in the context of halal industries using the TCCM framework-based review approach. A research agenda is proposed to advance research on technology acceptance and TAM in halal industries.

Abstract

Purpose

This study presents a comprehensive investigation of turnover intention within the context of higher education, specifically focusing on private universities in Egypt, to develop a robust conceptual framework to explore this phenomenon.

Design/methodology/approach

The study sample comprised both male and female tenured faculty members from private universities, and data were collected through questionnaires, resulting in 396 completed responses. Statistical analysis was conducted using SPSS and partial least squares structural equation modeling (PLS-SEM) software.

Findings

The study highlights the significant impact of work-life balance (WLB) and organizational commitment on turnover intention, with job satisfaction as a mediating factor. Additionally, the research reveals that emotional intelligence (EI) does not directly influence turnover intention, but its effects are fully mediated by job satisfaction.

Originality/value

This research not only advances the theoretical understanding of why academics contemplate leaving their positions but also underscores the significance of this topic. Moreover, by exploring turnover intention in the private education sector of the Middle East, the study addresses a notable gap in the existing literature.

Abstract

Purpose

The particle distribution in a fluid is mostly not homogeneous. The inhomogeneous dispersion of solid particles affects the velocity profile as well as the heat transfer of fluid. This study aims to highlight the effects of varying density of particles in a fluid. The fluid flows through a wavy curved passage under an applied magnetic field. Heat transfer is discussed with variable thermal conductivity.

Design/methodology/approach

The mathematical model of the problem consists of coupled differential equations, simplified using stream functions. The results of the time flow rate for fluid and solid granules have been derived numerically.

Findings

The fluid and dust particle velocity profiles are being presented graphically to analyze the effects of density of solid particles, magnetohydrodynamics, curvature and slip parameters. Heat transfer analysis is also performed for magnetic parameter, density of dust particles, variable thermal conductivity, slip parameter and curvature. As the number of particles in the fluid increases, heat conduction becomes slow through the fluid. Increase in temperature distribution is noticed as variable thermal conductivity parameter grows. The discussion of variable thermal conductivity is of great concern as many biological treatments and optimization of thermal energy storage system’s performance require precise measurement of a heat transfer fluid’s thermal conductivity.

Originality/value

This study of heat transfer with inhomogeneous distribution of the particles in a fluid has not yet been reported.
