Nonlinear mixed-convective entropy optimized the flow of hyperbolic-tangent nanofluid (HTN) with magnetohydrodynamics (MHD) process is considered over a vertical slendering surface. The impression of activation energy is incorporated in the modeling with the significance of nonlinear radiation, dissipative-function, heat generation/consumption connection and Joule heating. Research in this area has practical applications in the design of efficient heat exchangers, thermal management systems or nanomaterial-based devices.

Suitable set of variables is introduced to transform the PDEs (Partial differential equations) system into required ODEs (Ordinary differential equations) system. The transformed ODEs system is then solved numerically via finite difference method. Graphical artworks are made to predict the control of applicable transport parameters on surface entropy, Bejan number, Sherwood number, skin-friction, Nusselt number, temperature, velocity and concentration fields.

It is noticed from present numerical examination that Bejan number aggravates for improved estimations of concentration-difference parameter a_2, Eckert number E_c, thermal ratio parameter ?_w and radiation parameter R_d, whereas surface entropy condenses for flow performance index n, temperature-difference parameter a_1, thermodiffusion parameter N_t and mixed convection parameter ?. Sherwood number is enriched with the amplification of pedesis-motion parameter N_b, while opposite development is perceived for thermodiffusion parameter. Lastly, outcomes are matched with formerly published data to authenticate the present numerical investigation.

To the best of the authors' knowledge, no investigation has been reported yet that explains the entropic behavior with activation energy in the flowing of hyperbolic-tangent mixed-convective nanomaterial due to a vertical slendering surface.

This study aims to study the impact of corporate governance (CG) versus ethical investment on the firm performance. It takes into account the firms of Bangladesh, India, and Pakistan for the purpose of the study. A composite variable of CG index and environmental, social, and governance (ESG) index is used to test the impact on the firm performance. Separate country wise and overall analysis is obtained. Regression analysis is used to obtain the results. Two measures of performance are used, one is return on assets (ROA) and other is Tobin Q. The findings of the study reveal that there is an impact of corporate governance index (CGI) on firm performance (overall and country wise) whereas ethical investment (EI) has an impact on firm performance when tested overall and no impact when checked for country wise results. The results further show that on country level, increase in CG measures may lead to positive results, but at the macro level, it may lower the performance. On the other hand, at the micro level, ethical finance may not show its impact; however, at the macro level, it has an impact. The study has implications for the investors and policymakers.

This paper presents a citation-based systematic literature review in the field of sustainability management for Arab countries. The aim is to assist potential researchers in this field to identify existing themes, gaps and other relevant information necessary for the further development of the research area.

A comprehensive list of keywords has been searched in the SCOPUS database to identify all the relevant articles in the field of sustainability management in Arab countries. After applying the relevant restriction criteria, manual screening of titles, abstracts and keywords was performed to identify the final sample. The final sample consists of 410 articles published in 218 different journals by 907 authors. Bibliometrix R-tool was used to conduct a comprehensive bibliometric analysis of the selected articles.

Findings indicate a growing trend of publications on sustainability management in the generally understudied Middle East and North Africa (MENA) region. Besides publication trends, citation analysis presents citation trends, most influential journals and authors, and most cited articles on sustainability management in Arab countries. Theme identification is shown through analyses of conceptual and intellectual structures. Finally, social networks in the field are discussed.

Information presented in this paper informs interested researchers about the current state in the field, relevant sources of knowledge, important literature on the topic, relevant authors and other valuable particulars. This systematic literature review helps researchers make further valuable contributions to the field of sustainability management in Arab countries.

To the best of the authors' knowledge, this paper offers a first comprehensive citation-based systematic literature review on sustainability management in Arab countries.

The purpose of this paper is to examine the relationship between attitude, subjective norm, perceived behavioural control, religiosity, knowledge and Shariah-compliance with intention to hold Shariah-compliant credit card (SCCC) amongst Muslims and non-Muslims.

Researchers used survey questionnaire to collect data and applied a purposive sampling method, then analyzing the data using descriptive statistics and also multi-group analysis of SmartPLS.

For Muslims, attitude, subjective norm, Shariah-compliance, knowledge and religiosity are positively significant. While for non-Muslims, only attitude and subjective norm are positively significant to intention to hold SCCCs.

The behavioural study only focusses on intention to hold Islamic credit cards, which is constraining the extended model of the theory of planned behaviour (TPB) without the actual performance of the behaviour, which is holding SCCCs. Secondly, the research caters for a single method, namely, quantitative without including the qualitative method to better understand and explore other factors affecting consumers’ behavioural intention. The qualitative part can be carried out by conducting interviews with practitioners, regulators and customers. Thirdly, the cultural dimensions are not combined as parts of TPBs’ antecedents for extended model that could be affecting intention, as Malaysia has diverse ethnic groups with different religious background.

In terms of managerial implications, the findings will further assist financial service providers to develop more effective marketing strategies for Islamic financial products not just to cater for the Muslims but also the non-Muslims, who are increasingly attracted to Islamic banking. As many Muslims are still holding conventional credit cards, it is timely for the Islamic financial institutions to attract them with the SCCCs.

Financial marketers are expected to be qualified and well-versed on the different Islamic product structures and also the conventional products. By having such enables them to enlighten and create awareness amongst the targeted consumers in seeking Shariah-compliant financial-related products.

The research will contribute to new theoretical knowledge of an extended behavioural model in relation to customers’ perception towards SCCCs’ acceptance.
