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.

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.

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.

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 examine why tax reforms fail and explores how tax collection can be improved within a developing country context.

Data comprise 28 semi-structured interviews with taxpayers, tax experts and tax authority personnel based in Pakistan. The results are analysed using a combined lens of taxpayer trust and tax agencies’ capabilities.

Tax reforms failed to build taxpayers’ trust and tax agencies’ capabilities. Building trust is challenging and demands extensive ongoing engagement with taxpayers while yielding gradual permanent results. This requires enhancing confidence in government; educating taxpayers; removing complexities; introducing transparency and accountability in tax agencies’ operations and the tax system; promoting procedural and distributive justice; and reversing perceptions of corruption through reconciliation and stakeholder inclusivity. Developing tax agencies’ capabilities requires upgrading outdated technologies, systems and processes; implementing governance and organisational reforms; introducing an oversight board; and recruiting and training skilled professionals.

The findings can assist policymakers and tax collection authorities in understanding why tax reforms fail and identifying potential solutions.

This study contributes to the emerging literature by exploring tax administration failures in developing countries. It contributes to the literature by engaging stakeholders to understand why reforms fail and potential solutions to stimulate tax revenues.

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

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).

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.

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.

This study investigates the relationship between family incivility (FI) and burnout in line with the conservation of resources theory and work–home resources model. The authors also examine the conditional indirect effects of psychological capital (PsyCap) and life satisfaction (LS) in the aforementioned relationship. The purpose of this paper is to address these issues.

Data were collected using a time-lagged methodological design by administering a structured questionnaire among 296 rural doctors. The collected data were analyzed using PROCESS macro in Statistical Package for the Social Sciences (SPSS) 23.

The study indicates that FI is an emotional home demand and influences burnout at the workplace through the depletion of LS. At the same time, PsyCap proves to be a vital resource that mitigates the adverse effects of FI and burnout.

This study adds to the work–family and well-being literature by exploring the underlying mechanism through which FI connects to different outcomes. The implications of these findings for applications and extension of the work–home resources model to the family domain is elaborated in detail.

This study is among the first to empirically substantiate the long-term adverse consequences of FI and its potential for negatively affecting the work domain by inducing long-term psychological disorder “burnout.”

This study aims to understand the relationship between family incivility and employees' organisational citizenship behaviour. It also explores the mediating role of negative rumination and the moderating roles of workplace friendship and optimism.

To test the hypothesised relationships, 381 responses were collected from employees at two-time points. The hypothesised relationships were tested using process macros.

The results indicated that family incivility is negatively related to organisational citizenship behaviour and increases negative rumination. The study also established the mediating role of negative rumination in the relationship between family incivility and organisational citizenship behaviour. The study also supported the buffering role of workplace friendship and optimism in the relationship between family incivility and negative rumination.

The study findings extend the understanding of how a non-work stressor can influence employee behaviour in the organisation. The study findings provide valuable directions to mitigate family incivility's adverse effects and extend the existing body of knowledge.

The study is unique as it links family events to work outcomes. Only a few scholarly attempts were undertaken to understand the effect of family incivility on employees' work behaviours. By explaining the mechanism and conditions, the study has a unique value to the scholarship.

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.

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.

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.

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.

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.

This paper aims to examine existing literature on halal food consumption from the perspective of consumer behaviour research. It identifies progress, current state and gaps and provides direction for future research to advance the field.

This paper reviewed papers from 2007 to 2023 using Scopus and WOS databases. The review used the Theories–Context–Characteristics–Methods (TCCM) framework and followed the scientific procedures and rationales for systematic literature reviews (SPAR-4-SLR) protocol.

The review summarises the methods, theory and approaches used in the topic and presents key findings and a proposed framework. It can guide future researchers in developing their models, making it a valuable starting point for future research. Despite the existence of SRL in halal food to the best of the authors’ knowledge, this work is the first review that proposes a model for halal food in consumer behaviour.

This review provides a twofold contribution. First, this review's theoretical contribution is advancing consumer behaviour literature on halal food. Second, this work's practical contribution is to enrich practitioners' understanding of the antecedents of consumer behaviour regarding halal food. This is the first review proposing a consumer behaviour model for Halal food. It makes a theoretical contribution to understanding consumer behaviour on Halal food and provides practical insights for practitioners.

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.

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.

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%.

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.

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.

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.

The real estate markets may be significantly influenced by the uncertainty in global economic policy. This paper aims to evaluate the time-varying connectedness between global economic policy uncertainty and regional real estate markets to understand how regional real estate markets and uncertainty in global economic policy are related throughout time.

The current study includes the monthly data from April 2007 to August 2022 of major regions (i.e. Asia Pacific, Europe, Africa, North America and Latin America). Moreover, the authors use the time-varying parameter vector auto-regression (TVP-VAR) approach for the analysis.

The finding revealed a significant level of connectedness among global economic policy uncertainty and selected regional real estate markets. The result highlights more than 80% connectivity between the two variables, which makes the current study valuable. Furthermore, results determine Africa and North America are the shock transmitters; thus, they are considered safe-haven for investors to invest in these markets.

The main novelty is that this research highlights the time-varying connectedness between global economic policy uncertainty and five regional real estate markets (Africa, Asian Pacific, Europe, Latin America and North America) using TVP-VAR. Furthermore, the authors used the standard and poor daily real estate investment trust (REIT) indices for the selected REIT markets. Finally, this research suggests practical implications for real estate investors, property developers, stakeholders, policymakers and managers to revise their current policies to maintain the real estate market stability during economic and political uncertainty or in other uncertain situations.

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.

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).

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.

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.

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.
