The aim of this study is to develop a mathematical model for solar power generation system which starts with the quantification of solar resources on different characteristic surfaces at any location.

This study is based on a detailed quantitative analysis of solar potential at three different cities of Saudi Arabia: Riyadh, Mecca and Sharura. Direct normal insolation is calculated for one-axis tracking surfaces with rotation about East–West (EW) and North–South (NS) horizontal axes, a two-axes tracking surface and a fixed surface tilted at the latitude of each location and facing south. One-axis tracking parabolic trough collector with rotation about horizontal EW and NS axes, and photovoltaic systems are modeled; their performances and heat and optical losses from both systems are quantified for each location.

The findings demonstrate that energy output from the selected solar technologies is maximum and relatively stable in Sharura, whereas Mecca and Riyadh showed large variations during the course of the year.

A comparative analysis between the solar technologies would be very helpful for policy decisions to choose the best option.

The environmental performance of organizations has come under public policy limelight since the phenomenal increase of natural resource degradation and industrial waste. Thus, green concepts have been put forward, but the implementation of green practices faces many barriers and challenges. These barriers require attention as organizational practices are negatively affecting the environment leading to global warming and climate change. Therefore, this chapter systematically identifies four internal barriers including inadequate management commitment and support, insufficient technology competence and infrastructure, financial constraints, the uncertainty of economic benefits, and eight sub barriers within an organization concerning green concepts implementation. Moreover, this chapter also identifies four external barriers including lack of stakeholder's interest, inadequate environmental administrative support, scarce academic research, and lack of green collaborative practices, and eight sub barriers outside an organizational context concerning green concept implementation. The barriers in this research were identified by reviewing the existing literature on the topic. This chapter advances the green literature by identifying multiple barriers and challenges to the successful implementation of green concepts in organizations. This is of significance as if these barriers are tackled strategically, it would reduce environmental degradation problems and help make financial gains. Moreover, this research can help managers understand the key barriers to green concept implementation and provide guidance to them when attempting to implement green practices in their organizations. This research would also motivate researchers to extend further investigation on how to overcome such barriers and find out strategies to mitigate the barriers to green concept implementation to effectively address environmental issues.

The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.

The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.

There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.

Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.

This paper covers a long time span to determine whether the philosophical projects have been effective.

This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

This study aims to investigate two primary objectives. First, this study examines the influence of modified service quality dimensions on Islamic bank customer satisfaction using a compliance, reliability, empathy, assurance, tangible, operational efficiency, responsiveness (CREATOR) model. Second, the study explores the relationship between customer satisfaction, trust, loyalty and word of mouth (WOM) in Islamic banking of Pakistan.

The proposed model was analyzed using PLS-SEM-based approach. A total of 312 usable responses were used for data analysis.

The results indicate that all CREATOR dimensions have a significant positive impact on Islamic banks’ customer satisfaction. Similarly, this study also found a significant positive relationship between customer satisfaction, trust, loyalty and WOM. Overall, this study modified a well-established service quality framework by successfully implementing the CREATOR model in Islamic banking.

This study will provide helpful policy guidelines for Islamic bank managers improve their service quality and strengthen their relationships with existing and new customers. The authors are also sure that their proposed model will add value to the ongoing service quality literature by indicating the role of operational effectiveness in increasing customer satisfaction and promoting positive WOM.

Intellectual capital (IC) is a paramount resource for competitiveness in the knowledge-based financial sectors of the economy. As financial technology advances, specifically in the banking industry, it is vital to understand the effect of IC on financial performance. This study aims to investigate the effect of IC on return on equity (ROE), with a unique emphasis on the moderating role of board attributes. Previous studies have overlooked this moderating role.

The study sample consists of 17 banks and a panel data set spanning 2016–2021, extracted from annual reports. Antel Pulic’s value-added intellectual coefficient (VAIC) model is used to compute IC. To analyze the data, a generalized least squares analysis is conducted. The robustness of the analysis is ensured by using the two-stage least squares (2SLS) econometric technique.

The findings indicate that both the VAIC and human capital efficiency (HCE) have a significant impact on the ROE of banks. In terms of moderation, it is observed that board size (BS) exerts a negative effect on the association between VAIC, HCE, structural capital efficiency and ROE. Additionally, BS positively compounds the connection between capital employed efficiency and ROE. Similarly, the presence of independent directors (IND) significantly moderates the effects of VAIC and its components on the ROE of banks in Pakistan.

Banks should focus on the HCE for a higher ROE. Moreover, banks ought to prioritize appointing more independent directors in the boardroom for effective utilization of IC and greater ROE.

The findings of the study, which analyzed data from Pakistan’s banking sector, are original and provide additional insights into the literature on IC and board attributes.

Islamic Insurance (Takaful) played a dynamic role in Islamic Social Finance (ISF). The popularity of the Takaful concept is being increased with each passing day. To describe the process, it is important to understand past areas of research, research differences, areas of unknown Takaful research, as well as the existing data. However, the purpose of the paper is to provide a comprehensive analysis of the development of qualitative research by carefully examining the nature of science and aspects of social relations in ISF.

Field, concerns with analysing and measuring the scholarly literature, quantitative characteristics of sciences and scientific technologies are known as scient metrics. This research includes queries such as “Islamic Insurance”, “Takaful” and “Shariah Insurance” as a reference in “Article title, Abstract and Keywords” based on Scopus from 2002 to 2022. This analysis was conducted in February 2022. The Bibliometrics, R-Studio, VOSviewer and Excel software are used to analyse the collected data and apply the bibliometric analysis.

The gist of the results and findings is that there are clear research gaps in the existing literature on Takaful. The available research on this subject does cover historical background, concept and models of Takaful and customer satisfaction towards Takaful model. Very important areas such as use of technology for bringing innovation in Takaful products and Shariah issues in existing practice and their solutions were not found in the present literature on Takaful.

This is the comprehensive research article to examine current literature on Takaful with bibliometric analysis. Results and potential areas of this research could be much helpful for scholars and researchers to create more dynamic improvements in the scientific development of Takaful in ISF.

This study aims to investigate the performance of Sustainable Development Goals (SDGs) of public listed companies (PLCs) in Malaysia through their SDGs disclosure. In addition, it examines the impact of integrated reporting (IR) quality on the SDGs’ performance.

Data are collected from an initial sample of Malaysia’s top 100 market-leading PLCs from 2016 to 2020. Univariate and multivariate analyses were used to test the research hypotheses.

The results reveal an increasing trend in SDGs’ performance. Companies contributing toward the 17 SDGs grew from 14% in 2016 to 78% in 2020. On a priority basis, the average score of the five years showed that the Malaysian PLCs are paying more attention to SDG 8 Decent Work and Economic Growth (53%); SDG 12 Responsible Consumption and Production (43%); and SDG 13 Climate Action (42%). In addition, the fixed effects regression analysis proves that companies with higher IR quality are more likely to provide better SDGs disclosure.

This study provides insights to policymakers, investors and management on the vital role of businesses in supporting the SDGs’ achievement and how IR reveals a turning point in achieving the United Nations SDGs’ agenda.

This study provides a clearer understanding of the activities seeking to achieve the SDGs and the influence of IR on them. This opens the debate for future research.

To the best of the authors’ knowledge, this study is a pioneer in examining whether the quality of IR influences SDGs disclosure among large companies in one of the emerging economies in Southeast Asia in its early application stage.

This study aims to compare capital structure determinants' effect on the leverage levels of Shariah-compliant (SC) and noncompliant (NC) firms in Pakistan. This study also estimates and compares the capital structure adjustment speed for both firm types.

Based on the Karachi Meezan Index screening criterion, a balanced panel of 117 SC and 68 NC firms listed on the Pakistan Stock Exchange from 2008 to 2018 was constituted. This study used the generalized method of moments to identify the significant determinants of capital structure and estimate the speed of adjustment. In addition, the F-test was used to check whether the effect of the determinants on the leverage is same for SC and non-SC firms.

The authors found that different determinants affect both firm types' leverage levels (book and market) differently. The authors also found that the adjustment speed of SC firms toward their target leverage ratio is slower than their NC peers. Lastly, significant variation was observed in the results under different screening criteria.

This study fills the literature gap by providing a comprehensive comparison of the capital structure decisions of the SC and non-SC firms. Because this study is limited to Pakistan, generalizability would be an issue.

This study will guide the management of SC and non-SC firms about which factors are reliably important in choosing their capital structure. The findings also call for bringing harmony in the different Shariah screening criteria being in practice.

To the best of the authors’ knowledge, this is the first comparative study that identifies the significant capital structure determinants for SC and NC firms and investigates their effect on the leverage of both firm types. By testing joint hypotheses of same relationship, this study seeks to determine if, because of Shariah restrictions, the capital structure determinants of SC firms are similar to NC firms or they exhibit different behavior. The authors also repeat their analysis using other prominent screening criteria to assess the consistency of their results.

This study aims to determine the role of intellectual capital (IC) on financial performance (FP), the mediating effect of high-performance work practices (HPWPs) and the moderating role of big data analytics on the banking sector operating in Pakistan.

This study collected quantitative and cross-sectional data using structured questionnaire forms distributed to selected targeted respondents using a convenient sampling technique. The 518 useable questionnaires were analysed using the SmartPLS software through a structural equation modelling technique to test the proposed research hypotheses.

The study results revealed that IC has shown an impact on FP. The role of HPWP significantly mediates between IC and FP, while the moderating role of big data analytics remains insignificant.

This study highlights IC's role in enhancing FP in the Pakistani banking sector. It will bring a higher quality IC in the banking sector, and they will be better positioned to serve the community. Policymakers need to invest in IC and HPWP and utilise BDA, which will boost FP and uplift the quality of the banking sector.

This study extends the concept of IC and adds the theoretical role of HPWPs and big data analytics in the literature on IC, along with the contextual application. The study also develops a unique role of the integrated IC model theory with a relationship to the banking sector of Pakistan.

The unique nature of the construction sector makes it fall behind other sectors in terms of productivity. Monitoring construction productivity is crucial for the construction project's success. Current practices for construction productivity monitoring are time-consuming, manned and error prone. Although previous studies have been implemented toward reducing these limitations, a gap still exists in the automated monitoring of construction productivity.

This study aims to investigate and assess the different techniques used for monitoring productivity in building construction projects. Therefore, a mixed review methodology (bibliometric analysis and systematic review) was adopted. All the related publications were collected from different databases, which were further screened to get the most relevant based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) criteria.

A detailed review was performed, and it was found that traditional methods, computer vision-based and photogrammetry are the most adopted data acquisition for productivity monitoring of building projects, respectively. Machine learning algorithms (ANN, SVM) and BIM were integrated with monitoring tools and technologies to enhance the automated monitoring performance in construction productivity. Also, it was observed that current studies did not cover all the complex construction job sites and they were applied based on a small sample of construction workers and machines separately.

This review paper contributes to the literature on construction management by providing insight into different productivity monitoring techniques.
