The purpose of this study is to examine the relationship between corporate governance and financial soundness of Islamic banks. Precisely, this study examines the Shariah Board’s characteristics and empirically diagnoses its impact on the financial soundness of Islamic banks.

In this case, the level of bank soundness is individually measured using the z-score indicator. Regression analyses are applied to test the impact of the Shariah Board’s characteristics on the financial soundness of Islamic banks, using a panel data set of 67 Islamic banks – covering 20 countries during the period 2005–2014.

The model shows that the size of the Shariah Board has a negative and significant impact on the financial soundness of Islamic banks. However, the Shariah scholar with knowledge in finance/accounting, the presence of Mufti, the interlocked Shariah scholar and the foreign Shariah scholar do not have any significant impact on the financial soundness of Islamic banks.

This study contributes to fill the gaps in the literature that discussed the Shariah Boards’ role in the governance of Islamic banks. In addition, it provides practical implications to the Shariah Boards’ members in the Islamic banks and calls for setting a sufficient number of scholars for each Shariah Board.

With this paper, the authors aim to clarify the relationship between Shariah Board and financial soundness of the Islamic banking, and provide additional insights to the emerging literature of Islamic banking. Contrary to previous research studies, the authors use an additional hypothesis, i.e. the presence of Mufti that has a positive and significant effect on the financial soundness of Islamic Banks. Methodologically, the authors incorporate a new measure to evaluate empirically the impact of Shariah Board members with knowledge of finance and accounting on the financial soundness of Islamic banks.

The purpose of this paper is to understand the effect of engine operating conditions and lubricant friction modifier on direct acting tappet rotation. In this research work, novel method of measuring engine tappet rotation speed has been developed. The technique is so novel. It allows the measurement on real production engine with no modification to the engine tappet bore. Also, In this paper, the effect of engine operating conditions and the effectiveness of friction modifier on tappet rotation is reported.

For the very first time, for the purpose of measuring follower rotation in a real production engine, a 4 × 6 mm2 electronic chip called Gradiometer is mounted outside the tappet housing, allowing the monitoring of tappet rotation speed without the need to machine a hole in the tappet bore. This novel technique is adopted on Mercedes Benz OM464 engine to study the effect of engine conditions and lubricant chemistry on tappet performance.

The main outcome of this research work is the development of novel method of measuring tappet rotation. Also, during the experiments, it was revealed that although friction modifiers help in reducing friction at the cam/tappet interface, they can also adversely affect the tappet rotation speed.

The novel technique developed in the research work is one of the most cost effective and simple to use. Researches can adopt the technique to study the tribological performance of direct acting tappet on real production engine. Researches acknowledge the effectiveness of friction modifiers in valve train but its effect on rotation which plays a key role in the component durability has not been the focus of most of the researches mainly due to lack of effective techniques.

Anglo-centric scholarship understands authenticity of online mediated performance for acquiring fame as a context-dependent claim, requiring labor in displaying a vulnerable self that is evaluated and validated by a relevant audience. This book chapter examines this concept in a non-Western context through a case study of a Pakistani microcelebrity, Qandeel Baloch. By explaining how Pakistani broadcast celebrity performances continue to be evaluated by religious and moral standards, this analysis finds how a transgressive performance shapes an authentic microcelebrity claim on social media.

In this paper, the authors explore the specific nature of material-based legitimation and examine how it differs from other forms of legitimation. Prior studies of institutional legitimacy have predominantly focused on the discursive and iconic aspects of legitimation, with much less focus placed on the role of materiality. To advance our argument, the authors introduce the notion of enactive legitimation. The authors suggest that legitimation is derived from and supported by the ongoing engagement and interaction with materials and material-based practices. To elaborate our argument, the authors study a case of the use of material signification to legitimize a new financial product within Islamic banking. The authors show that the legitimacy of the product is grounded in materials and the materiality of a number of ritualized practices. Materials and practices, however, also impose their own specific constraints on the process, and do so in ways that are more evident than when legitimation is based on signs and symbols (both language and images). The paper contributes to practice-based institutionalism by leveraging one of the central tenets of practice theory to extend the understanding of legitimation. It also illustrates what practice-based sensitivity may look like in action.

The purpose of this paper is to study the differences in fatwa amongst official fatwa institutions in Malaysia comprising the State Mufti’s Departments (SMDs), the National Fatwa Committee Muzakarah (NFCM) and the National Bank Shariah Advisory Council (NBSAC) regarding the conditional gift issue and to propose a uniformed fatwa by taking an approach of celebrating views of all the official fatwa institutions involved.

The methodology used for this study is qualitative; data was collectedthrough library research and field studies.[AQ1] The library research was accomplished by examining books, statutes and related circulars, while field studies were conducted through unstructured interviews with eight Shariah (Sharia) officers and two academicians from SMDs, NFCM, NBSAC and public universities.

The findings of the study found that the conditional hibah (ruqba and 'umra) is valid as far as gifting is concerned, while the conditions pertaining to it are null and void. The findings also found that the concept of mura’ah al-khilaf and ma’alat al-af’al can be practised by applying conditional hibah to maintain maslahah, as provided under the concept of maqasid al-Shariah. Hence, this study proposed that formal fatwa institutions consisting of SMDs, NFCM and NBSAC issue a comprehensive guideline in contracting conditional hibah by providing an explicit provision on the recognised and different opinions about the said hibah.

The study analyses the differences of opinions of the official fatwa on conditional hibah issued by SMDs, NFCM and NBSAC based on the discipline of usul al-fiqh. It is found that conditional hibah is not allowed in Islamic law. It also found that conditional hibah granted by the NBSAC is not in adherence to the strict permission granted by Islamic law. Therefore, taking into consideration all the fatwas issued by the fatwa bodies, the researchers proposed to celebrate all official fatwas using the method of mura'ah al-khilaf and ma’alat al-af'al.

The graphical representation of a finite element model (undirected graphs) imposes some constraints on the choice of storage techniques and data structures; first, the storage structure must deal efficiently with sparse matrices; second, the retrieval method of an edge, of a finite element model, around selected nodes must minimize the multiple occurrences of the same edge if plotting efficiency is to be achieved; and third, the insertion and extraction of edges in a data structure must be independent of the selected nodes identification scheme. This paper evaluates the relative merit of elementary storage methods and data structures in terms of the time and space costs required to satisfy the above constraints. The theoretical costs are derived and the experimental costs are evaluated and compared. Depending on the homogeneity of the degree of the nodes, a static data structure or a linked list data structure using listed or sectioned hashing techniques are shown to yield the minimum time and space costs.

There is a continuous drive in automotive sector to shift from conventional lubricants to environmental friendly ones without adversely affecting critical tribological performance parameters. Because of their favorable tribological properties, chemically modified vegetable oils such as palm trimethylolpropane ester (TMP) are one of the potential candidates for the said role. To prove the suitability of TMP for applications involving boundary-lubrication regime such as cam/tappet interface of direct acting valve train system, a logical step forward is to investigate their compatibility with conventional lubricant additives.

In this study, extreme pressure and tribological characteristics of TMP, formulated with glycerol mono-oleate (GMO), molybdenum dithiocarbamate (MoDTC) and zinc dialkyldithiophosphate (ZDDP), has been investigated using four-ball wear tester and valve train test rig. For comparison, additive-free and formulated versions of polyalphaolefin (PAO) were used as reference. Moreover, various surface characterization techniques were deployed to investigate mechanisms responsible for a particular tribological behavior.

In additive-free form, TMP demonstrated better extreme pressure characteristics compared to PAO and lubricant additives which are actually optimized for conventional base-oils such as PAO, are also proved to be compatible with TMP to some extent, especially ZDDP. During cylinder head tests, additive-free TMP proved to be more effective compared to PAO in reducing friction of cam/tappet interface, but opposite behavior was seen when formulated lubricants were used. Therefore, there is a need to synthesize specialized friction modifiers, anti-wear and extreme pressure additives for TMP before using it as engine lubricant base-oil.

In this study, additive-free and formulated versions of bio-lubricant are tested for cam/tappet interface of direct acting valve train system of commercial passenger car diesel engine for the very test time. Another important aspect of this research was comparison of important tribological performance parameters (friction torque, wear, rotational speed of tappet) of TMP-based lubricants with conventional lubricant base oil, that is, PAO and its formulated version.

Based on the Social Exchange Theory and Conservation of Resources Theory, this study aims to investigate the impact of transformational and transactional leadership on scientists’ innovative work behavior (IWB). It also examines the mediating effect of scientists’ psychological empowerment in the relationship between transformational leadership and IWB as well as between transactional leadership and IWB.

This study uses a quantitative design and uses data from a sample size of 357 scientists from all five different subject domains of India’s largest civilian Research and Development (R&D) organization, the Council of Scientific and Industrial Research. Hierarchal component modeling (HCM) was performed for transformational leadership transactional leadership and psychological empowerment, whereas IWB was modeled as a first-order reflective construct. PLS-SEM was used to assess the study’s model and hypotheses.

It was found that transformational leadership is positively related to IWB and psychological empowerment mediates the relationship between transformational leadership and IWB. Moreover, transactional leadership was found to be positively related to IWB while psychological empowerment did not mediate the relationship between transactional leadership and IWB.

This study adds to IWB literature by empirically testing the mediating role of psychological empowerment between transformational leadership-IWB and transactional leadership-IWB link in the R&D context of an emerging economy using HCM.

This study aims to look at the current state of academic research on innovative work behavior (IWB) and how far it has progressed by using key performance analysis and science mapping techniques of bibliometric analysis.

This study has analyzed 246 publications from Web of Science database on IWB from 1989 to 2021. Data were analyzed using MS Excel and VOSviewer.

There has been a rise in the number of academic studies on IWB during the past decade. In addition, it was discovered that a significant percentage of papers had multiple authors working together on them and that collaborations between institutes in Asia and the developed world are taking place.

IWB research trends and trajectories may be assessed to enable academics and practitioners better understand the current and future trends and research directions. Future studies in this field might use the findings as a starting point to highlight the nature of the topic.

Bibliometric techniques provide a far more comprehensive and reliable picture of the field. This article has the potential to serve as a one-stop resource for researchers and practitioners seeking information that can aid in transdisciplinary endeavors by leading them to recognized, peer-reviewed papers, journals and networks.
