This paper aims to study the effects of various compatibilisers (maleic anhydride (MAH), methyl methacrylate/butyl acrylate emulsion lattice, and adhesion system (HRH)) on properties of carbon black (CB) filled with natural rubber (NR)/styrene-butadiene rubber (SBR)/ nitrile butadiene rubber (NBR) blends). A series of NR/SBR/NBR blends at a 30/30/40 blend ratio reinforced with 45 phr of CB was prepared using the master-batch method.

The tensile properties such as the tensile strength, stress at 100, 200 and 300% elongations, and elongation at break (EB)% were studied. Additionally, the morphological properties of compatibilised and uncompatibilised composites were compared to determine the optimal compatibiliser content.

The influence of compatibilisers appeared on all the properties studied. The properties of the blends compatibilised with prepared emulsion are very distinct from those of blends compatibilised with MAH and adhesion systems.

Interactions among the different components of blends at the interfaces have a high impact on the interfacial properties of the rubber blend.

Compatibilisers significantly improve the physicomechanical properties of the resulting composites with the loading of investigated compatibilisers because of the uniform dispersion of CB in the rubber matrix.

Using blends in the rubber industry leads to high-efficiency production of low-cost products.

The rubber blending has a significant positive effect on a wide range of applications such as structural applications, aerospace, military, packaging, tires and biomedical. Hence, improving the compatibility of blends will make new materials suitable for new applications.

This study aims to provide an overview of the development of corporate governance and ownership structure literature and offers a synopsis of the top contributors, influential articles, journals and potential research prospects on this subject.

This study used bibliometric analysis to review the literature. In all, 1,368 articles published between 1992 and 2022 in Scopus-indexed journals were considered.

This review reveals the top leading authors, institutions, countries and sources in the ownership structure research. Using bibliographic coupling, this study fetches four significant clusters. The theme of the first cluster revolved around cash holding. The second and third groups revealed how distinct characteristics of ownership impact the performance of the firm and disclosure decisions, respectively. The last and fourth cluster deals with risk-taking activities in financial institutions. Furthermore, this study suggests a road map in each cluster for future research.

Ownership structure plays a significant role in corporate governance by affecting manager incentives and determining the extent of monitoring. Previous studies have contributed to this field while focusing on the board of directors. However, no study synthesises the literature on ownership structure within corporate governance, which is the core element of the corporate governance system. Hence, this study gives a comprehensive overview and determines the latest and prominent research in ownership structure within corporate governance through bibliometric analysis.

This paper aims to propose a derivation of Shariah risk from both the Islamic finance theory and theory of contracts in Islamic law. Specifically, it deliberates the derivation of Shariah risk following the contracts validity and apprises the readers of the Shariah risk issues currently under debate.

This study reviews the relevant literature and presents an analysis of contract rulings through evidence derived from the Qur’an, Hadith and other secondary sources of Islamic law. Various theories of Islamic finance and Islamic law of contracts are identified, to examine the general principles and essential elements and conditions of a valid contract.

This analysis asserts that any circumstances that may render invalidity of the contract will trigger Shariah risk. More importantly, this paper highlights the implications of invalid contracts, based on the opinion of Hanafi jurists, who concluded that Shariah risk may be derived from any void or voidable contracts due to the failure of the contractual parties to comply with Shariah contractual obligations.

This paper emphasises the derivation of Shariah risk over theoretical approaches. It does not include an explanation in the form of any empirical model.

This is the first study that contributes to the field of derivation of Shariah risk, based on the theory from the Islamic law of contracts.

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.

The purpose of this paper is to examine the Shariah view on the legitimacy of requiring the entrepreneur to prove that he/she has complied with all business requirements in case the actual profit was below the expected profit in trust-based contracts such as mudarabah and musharakah.

This paper is part of the research which applies qualitative research approaches, including among others, content analysis, interviews, observations and descriptive analysis using fiqh muqaran (comparative analysis of jurists’ arguments) in few phases.

The study found that shifting the burden of proof to the fiduciary is the weightier view and necessary to ensure that both sides are protected. The considerations of protecting people’s wealth (ḥifẓ amwāl al-nās) and mitigating widespread greed (ṭamaʿ) are among the reasons for allowing elements such as ʿurf, tuhmah and dalālat al-ḥāl to be treated as bayyinah in trust-based contracts when the fiduciary is obliged to defend himself from litigation.

The study is meant to strengthen the practices of Islamic banks world wide.

Few protections can be applied for capital provider.

This study is meant to give solution in dealing with moral hazard of both parties, and to provide solution to the regulator for policy drafting and to increase confidence to the industry.

The finding is important in assisting the regulators in drafting the policy to protect both parties without neglecting the essence of trust-based contracts.

Cash waqf is a powerful financial instrument that deals with the issue of liquidity constraints in waqf institutions. While there are several models of cash waqf operating in different countries, there is increasing demand for innovative cash waqf models, especially within the financial technology context. This paper aims to propose a practical alternative model of funding for waqf institutions using the concepts of crowdfunding and cash waqf.

This study evaluated the literature relevant to cash waqf models that have been implemented in different countries and proposed a new viable alternative model.

Results offer an alternative financing model, named crowdfunding cash waqf model, for waqf institutions to overcome monetary constraints and enable development projects to be completed.

The current study has important implications for both officials and relevant stakeholders. It is sought to bring better consistency between cash waqf donors, solving the liquidity problem faced by waqf institutions, enhancing the transparency of waqf institutions and their use of waqf funds, wealth circulation and financing businesses without interest-based loans (riba). By incorporating a crowdfunding and investment mechanism in the model, this method of collecting funds will assist governments in reducing their expenditure on waqf institutions and other social development programmes.

The proposed model differs from current methods of generating cash waqf, including those are also internet-based. The proposed model is devised to help waqf institutions achieve financial sustainability by including an investment mechanism in the model to sustain the development of waqf projects.

This paper aims to derive a compatible Shariah opinion on the permissibility of using cryptocurrencies by Muslims by reviewing the opinions expressed by Shariah scholars on the permissibility of cryptocurrencies.

This is a qualitative desk review research where the opinions expressed by the Shariah scholars on the permissibility of cryptocurrencies and the issues related to it have been analyzed using the literature. All the Shariah parameters checked pertaining to currencies have been studied and assessed to derive the Shariah opinion.

The research findings suggest that cryptocurrencies do not fully meet the characteristics of money according to Shariah principles. Scholars debate their classification as a medium of exchange due to concerns about volatility, intrinsic value and governance. The treatment of cryptocurrencies varies, and their decentralized nature prevents monopolization. Governance and resistance to manipulation are facilitated by blockchain technology. Classifying cryptocurrencies as hard money and their recognition as the primary unit of account face challenges. While they can be a store of value, price volatility and regulations must be considered. The network effect is crucial for their success, and their supply is controlled through complex protocols. These findings have implications for policymakers in Islamic finance.

The differences in Shariah opinions on using cryptocurrencies have been a major debate in the Islamic financial industry. A clear and comprehensive study is not found on the differences in the Shariah opinions on their reasonings, which is important for researchers and professionals in the field. Therefore, this research provides valuable insights for policymakers, scholars and practitioners in Islamic finance, contributing to the understanding of applying Islamic principles to cryptocurrencies.

The purpose of this paper is to estimate the import demand function for halal meat in member countries of the Organization of Islamic Cooperation (OIC) and to suggest some policy recommendations for OIC members that can enhance intra-OIC halal meat trade.

By using an augmented gravity model, this study empirically estimates the major determinants of halal meat import demand in OIC member countries. Moreover, a major determinant is the difference in Islamic jurisprudence (fiqh).

The results of this study show that the variation in Islamic jurisprudence is one of the primary determinants of intra-regional trade of halal meat import demand in OIC member countries.

Although trade flows are set up in several years and lag variables are well capable to examine trade flows, this study only includes the static nature of halal meat trade flows toward selected top 20 OIC member countries.

This study suggests that developing a common halal meat market and one halal certification body under the OIC can enhance intra-OIC halal meat trade, this may be a challenge given the five diverse interpretations of halal meat within Islamic jurisprudence among OIC member countries.

This paper identifies the role of Islamic jurisprudence (fiqh) in determining the import demand of halal meat in OIC countries, which has not been addressed in empirical literature. It also provides some policy implications to ameliorate the declining trend of intra-OIC trade flows of halal meat.

Islamic finance and Halal product sectors are thriving successfully. This chapter is a general review of the perception of Asian consumers on Islamic finance and Halal sectors in the global Halal economy.

The first section will briefly describe the Halal concept in both Islamic finance and Halal industries, and the growth of both sectors in Asian countries. The second part highlights the review of Asian consumers’ perception towards Islamic finance products and Halal products.

The review found that the consumers’ perception towards the Islamic finance products and Halal products is distinctive. This is due to the diversity of Asian countries in terms of geography, religion, culture, ethnic, school of thoughts (madzahib), income per capita and government’s involvement.

The third part of the chapter concentrates on planning towards Halal marketing, which involves the move and future challenges in different layers of industries to gear up and strengthen the Halal economy.

The majority of Malaysian firms are small and medium-sized enterprises (SMEs), and the hospitality industry is no exception. However, a study on environmental management systems (EMS) reveals that relatively few studies have observed EMS implementation in small and medium-sized enterprises hotels (SMEHs). Hence, this study aims to determine the link between institutional influences and mediating effects of top managers' perceived benefits toward EMS implementation by Malaysian SMEHs.

The results of a questionnaire survey of 252 SMEHs managerial-level professionals using Smart-PLS software provide some explanation for the marginal action taken by these SMEHs to improve their environmental performance.

Based on the findings, five variables might stimulate the implementation of an EMS: regulatory influences, customer influences, competitor influences, employee influences and manager attributes influences.

This study significantly advances understanding of EMS and SMEHs, offering a replicable research framework applicable across industries and countries. Scholars can leverage the framework for further exploration, while managers should recognize institutional influences on EMS implementation.

Given that this study is one of the few that investigates the institutional influences and perceived benefits of EMS implementation, it may provide valuable information for future research on the hospitality industry and the SMEHs among researchers and practitioners.
