This study aims to examine diversity in the composition of Shariah supervisory boards (SSBs) of Islamic banks (IBs). It investigates diversity from two perspectives: existing composition of SSBs and the regulatory frameworks and standards of selected Organisation of Islamic Cooperation countries. Diversity characteristics include education, nationality, gender and age.

A list of all full-fledged Islamic commercial banks (FFICBs) globally has been carefully prepared and confirmed. Conventional banks with Islamic windows, non-commercial banks, takaful companies and other Islamic financial institutions are excluded. The available profiles of 428 SSB members have been scrutinised and analysed. These board members occupy 522 SSB positions in 238 FFICBs operating in 52 countries around the globe. From the regulatory perspective, 12 national and international Shariah governance frameworks and standards have been examined.

Findings of this paper indicate various levels of diversity in SSBs of the reviewed IBs. The level of diversity in educational background and in the nationality of SSBs can be described as generally acceptable. However, a lack of diversity in gender and age among SSB members is evidently observed in IBs. While the lack of age diversity in SSBs may be relatively justified as a common trend in the composition of corporate boards, SSBs of IBs are seriously lagging behind in gender diversity. On the regulatory level, this study concluded that provisions on diversity as a requirement in SSBs are almost non-existent in the existing regulatory frameworks and standards.

The major limitation of this study is the lack of available information on the SSB members.

This paper provides insights for IBs and policymakers concerned with the corporate governance of IBs and all Islamic financial institutions. First, it offers an excellent bird’s-eye view of the status of diversity in SSBs of IBs. Second, it motivates policymakers and standard-setting bodies to ensure, through the relevant regulatory frameworks, adequate levels of diversity in the composition of SSBs. Diversity in SSBs of IBs and Islamic financial institutions should be given special emphasis, not only in boards and top management positions but also in the workplace. This is of profound significance to the reputation of Islamic finance industry which has been recently under mounting pressure to translate the rhetoric about the Islamic finance industry being ethical, fair, just, equitable and inclusive into genuine implementations.

To the best of the authors’ knowledge, this study is the first of its kind to examine the diversity of SSB members from the regulatory as well as from the implementation perspective.

The chapter looks at policies regarding access to higher education (HE) for the Palestinian Arab minority in Israel (PAMI). Recently, HE among PAMI has expanded compared to previous years, but the proportion of PAMI students in Israeli institutions of HE (14%) is still not equal to the percentage of PAMI (20%). The Council for Higher Education (CHE) in Israel has been trying to increase the accessibility of PAMI students in institutions of HE through the implementation of several projects and academic programs and the expectation of reaching 17% in 2021. The chapter has three main aims: (1) to describe the decisions and recommendations of CHE for increasing the rate of peripheral students in HE, (2) to trace their implementation in HE institutions, and (3) to investigate the influences of these policies in schools through interviews with secondary school principals and secondary students in PAMI schools to understand how they act to improve students’ awareness of these initiatives and to improve access to HE for their graduates. A qualitative-phenomenological study analyzes policy guidelines regarding HE for PAMI as set out by the two main committees established by the Israeli CHE. The findings may have international significance since similar difficulties are encountered in access to HE among underprivileged or peripheral populations in other world states.

The current study focuses on the relationship between total quality management (TQM) and sustainable performance (SP) and examines how TQM practices can facilitate firms' achievement of sustainable performance. Knowledge management (KM), with its four dimensions, i.e. knowledge creation (KCR), knowledge acquisition (KAC), knowledge sharing (KSH) and knowledge application (KAP), is also an essential factor for organizations. Therefore, this study also focuses on the mediating role of KM in the relationship between TQM and sustainable performance.

This study used a survey method to collect data from the managers of 485 manufacturing SMEs working in five major industrial cities in Pakistan. Collected data were analyzed through PLS-SEM with the help of smart-PLS.

The study's findings reveal that TQM practices positively influence the environmental and economic sustainability of the firm. At the same time, there is no evidence that TQM practices positively affect the social sustainability of the firm. Results further elaborate that TQM practices significantly affect all four dimensions of KM. Moreover, KM positively affects the two dimensions of SP, i.e. economic and social sustainability, but surprisingly, the impact of KM on environmental sustainability is not found. Finally, results indicate the significant mediating role of KM between TQM and SP.

This study contributes to bridging research gaps in the literature and advances how TQM, directly and indirectly, helps firms improve sustainable performance via the mediating role of KM.

The purpose of this paper is to present an exploration of multiple slips and temperature dependent thermal conductivity effects on the flow of nano Williamson fluid over a slendering stretching plate in the presence of Joule and viscous heating aspects. The effectiveness of nanoparticles is deliberated by considering Brownian moment and thermophoresis slip mechanisms. The effects of magnetism and radiative heat are also deployed.

The governing partial differential equations are non-dimensionalized and reduced to multi-degree ordinary differential equations via suitable similarity variables. The subsequent non-linear problem treated for numerical results. To measure the amount of increase/decrease in skin friction coefficient, Nusselt number and Sherwood number, the slope of linear regression line through the data points are calculated. Statistical approach is implemented to analyze the heat transfer rate.

The results show that temperature distribution across the flow decreases with thermal conductivity parameter. The maximum friction factor is ascertained at stronger magnetic field.

In the current paper, the magneto-nano Williamson fluid flow inspired by a stretching sheet of variable thickness is examined numerically. The rationale of the present study is to generalize the studies of Mebarek-Oudina and Makinde (2018) and Williamson (1929).

This study investigates the short-run and long-run impacts of agricultural credit on Vietnam's agricultural GDP over the period 2004:Q4–2016:Q4, with the incorporation of agricultural labor, public investment and rainfall as important determinants of agricultural GDP.

This study applies the indicator saturation (IS) break tests and the autoregressive distributed lag (ARDL) bounds test with structural breaks to examine the credit–agricultural performance nexus. The causal relationships among variables are explored through the Toda–Yamamoto Granger causality test.

The results indicate that agricultural credit positively influences agricultural GDP in both the short-run and long-run. A unidirectional causal relationship running from credit to agricultural GDP is confirmed. The results also discover the positive and significant effects of labor and rainfall on agricultural GDP in the long-run.

The results imply that the government should focus on expanding agricultural credit as well as enhancing the efficiency of agricultural credit. Furthermore, formal credit institutions should be encouraged to work closely with farmers and agricultural enterprises to offer flexible lending periods and amounts to meet the real situation of agricultural production.

This study is the first to examine the credit–agricultural performance relationship at the macro-level in Vietnam. Based on the empirical results, the study provides crucial implications for policymakers to optimize the effectiveness of agricultural credit and enhance nationwide agricultural performance.

The purpose of this study is to inspect the corrosion inhibition of API N80 steel pipelines in uninhibited solution and inhibited with a synthesized surfactant compound [N-(3-(dimethyl octyl ammonio) propyl) palmitamide bromide] (DMDPP), which is prepared through a simple and applicable method.

Weight loss was inspected at five different temperatures of 25°C, 30°C, 40°C, 50°C and 60°C Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation were used at room temperature. Density functional theory was used to study the relation between the molecular structure and inhibition theoretically.

Adsorption of the prepared DMDPP fits the Langmuir isotherm model. The inhibition efficiency of the prepared DMDPP amphipathic inhibitor is directly proportional to temperature increase. Polarization results reveal that the investigated DMDPP amphipathic compound behaves as a mixed-type inhibitor. EIS spectra produced one individual capacitive loop.

The originality is the preparation of cationic surfactants through a simple method, which can be used as corrosion inhibitors in oil production. The synthesized inhibitors were prepared from low-price materials. The work studied the behavior of the synthesized surfactants in inhibiting the corrosion of the steel in an acidic medium. Electrochemical and theoretical studies were presented, besides gravimetric and surface examination.

The purpose of this paper is to analyze the heat transfer effects on the stretched flow of Oldroyd-B fluid in a rotating frame. Cattaneo–Christov heat conduction model is considered, which accounts for the influence of thermal relaxation time.

Based on scale analysis, the usual boundary layer approximations are used to simplify the governing equations. The equations so formed have been reduced to self-similar forms by similarity transformations. A powerful analytic approach, namely, homotopy analysis method (HAM), has been applied to present uniformly convergent solutions for velocity and temperature profiles.

Suitable values of the so-called auxiliary parameter in HAM are obtained by plotting h-curves. The results show that boundary layer thickness has an inverse relation with fluid relaxation time. The rotation parameter gives resistance to the momentum transport and enhances fluid temperature. Thermal boundary layer becomes thinner when larger values of thermal relaxation time are chosen.

To the authors’ knowledge, this is the first attempt to study the three-dimensional rotating flow and heat transfer of Oldroyd-B fluid.

This paper aims to explore how the role of the perception of good public governance reduces tax evasion (TE). Besides, this study investigates whether the nexus of public governance and TE differs between developed and developing economies.

Apart from the ordinary least squares (OLS) model, this study uses the linear mixed modeling technique. The World Governance Indicators and the multiple causes estimation (MIMIC) method are used to measure public governance. The shadow economy is used as a proxy for TE.

The results show that people's perceptions of public governance and the quality of government institutions are core elements that influence tax-evasion behavior. Besides, the rule of law (RoL) and political stability (PS) significantly impact tax-evasion behavior in developing countries. Nevertheless, the RoL, the control of corruption and PS are the most critical tax-evasion determinants among public governance indicators for developed countries. Regulatory quality shows a substantial positive relationship with TE in developed but not developing countries.

This paper provides a guide for policymakers on reducing tax-evasion behavior by paying more attention to maintaining the RoL and PS and fighting corruption. Additionally, this study highlights the importance of people's perceptions of the government's pursuit of the above policy-related improvements, which, in turn, affect their tax behavior.

To the best of the authors’ knowledge, this study is the first to explore the role of people's perceptions of improvements in public governance and how this can reduce TE behavior in developed and developing economies. Unlike prior studies, this study used the linear mixed model method, which is more advantageous than OLS and produces robust estimators.

The paper seeks to analyze the characteristics of higher education (HE) among Palestinian Arabs in Israel (PAI). It aims to indicate the main trends that have taken place in higher education since the establishment of the State of Israel, especially in the last decade, and to examine the main factors that have hindered access to higher education for this minority group.

The study is based on a meta‐analysis of official statistics and other official documents, and on an analysis of relevant recent research studies.

The analysis shows that although there has been an increase in the numbers and percentages of PAI studying in Israeli HE institutes, especially for women, structural blocks still hinder their access to Israeli HE institutes, a situation exacerbated by their deficient preparation in secondary school. Their disproportionate under‐representation in the HE system reflects policies relating to power distribution and control in Israeli society.

Policy favoring re‐distribution of power alongside affirmative action legislation could influence the structure of the HE system and improve PAI minority representation in Israeli HE institutes.

The paper indicates the need for affirmative action to increase the Palestinian minority population's access to higher education in Israel.

This paper aims to explore the flow of nanofluid over bi-directional stretching sheet in the presence of magnetic field and linear thermal radiation.

In this study, water is taken as a base fluid, and copper is diluted in the base fluid. Further, four different shapes of nanoparticles are considered for the analysis. The governing nonlinear partial differential equations are transformed into the system of ordinary differential equations after using the feasible similarity transformations. Solution of the model is then performed by means of Runge–Kutta scheme.

Influence of the emerging dimensionless parameters on velocity, temperature, skin friction coefficient and local rate of heat transfer are studied with the help of graphs.
