Sharīʿah Secretariat plays a significant role in assisting Sharīʿah Supervisory Boards (SSBs) in their role in achieving Sharīʿah compliance in Islamic banks (IBs). The key objective of the study is to develop a organizational framework of the Sharīʿah Secretariat for the IBs in Bangladesh.

The study applied qualitative case study research. The data have been collected from 17 respondents through semi-structured interviews from IBs and professional experts in Bangladesh.

This study proposes a full-time Sharīʿah Secretariat and several departments for further enhancement of the Sharīʿah functions in IBs in Bangladesh. The framework proposed in this study covers the formation, functions, composition, qualification, reporting line, independence, remuneration and terms of appointment of the Sharīʿah Secretariat to set a uniform benchmark for all IBs in Bangladesh. It is anticipated that the outcomes of this research will assist to further strengthen the Sharīʿah governance of IBs in Bangladesh.

This research contributed to the national and global regulatory authorities and IBs by proposing a Sharīʿah Secretariat framework for the smooth functioning of the IBs in Bangladesh. The framework proposed in this study covers the formation, functions, composition, qualification, reporting line, independence, remuneration and terms of appointment of Sharīʿah Secretariat.

This study proposed a framework which is considered the first organizational framework so far for the Sharīʿah Secretariat of IBs in Bangladesh. IBs can apply this proposed framework to form their Sharīʿah Secretariat structure.

There are a number of differences in the current Sharīʿah screening guidelines formulated by Sharīʿah scholars associated with world-renowned index providers and financial institutions. The purpose of this study is to highlight the consequences of such differences on the portfolio level outcomes for Sharīʿah-compliant investors. This study also investigates the cost of adopting an alternative stock selection methodology.

Seven Sharīʿah-compliant equity portfolios (SCEPs) are created from the active constituents of the S&P 500. Size, sector allocation and financial performance of the resulting seven portfolios are evaluated for the period 1984–2019. Style analysis is performed to attribute the difference in financial performance caused by the choice of selection criteria to different risk factors. The cost of switching the selection criteria is evaluated with turnover analysis and break-even transaction cost.

The choice of stock selection criteria has a significant effect on the size, sector bets and financial performance of the portfolios. Those portfolios which are constructed with market capitalization-based screens outperform portfolios constructed with total assets-based screens. The turnover analysis revealed that SCEPs are relatively costly in practice.

This study investigates the performance of Sharīʿah-compliant portfolios in the context of seven different screening guidelines. The effects of transaction cost and performance attribution to different risk factors represent the key contributions of this study.

After 15 years of research, this paper aims to present a review of the academic literature on the ISO/IEC 27001, the most renowned standard for information security and the third most widespread ISO certification. Emerging issues are reframed through the lenses of social systems thinking, deriving a theory-based research agenda to inspire interdisciplinary studies in the field.

The study is structured as a systematic literature review.

Research themes and sub-themes are identified on five broad research foci: relation with other standards, motivations, issues in the implementation, possible outcomes and contextual factors.

The study presents a structured overview of the academic body of knowledge on ISO/IEC 27001, providing solid foundations for future research on the topic. A set of research opportunities is outlined, with the aim to inspire future interdisciplinary studies at the crossroad between information security and quality management. Managers interested in the implementation of the standard and policymakers can find an overview of academic knowledge useful to inform their decisions related to implementation and regulatory activities.

This paper aims to determine whether Islamic banks (IBs) and conventional banks (CBs) in Tunisia are distinguishable from one another based on financial characteristics during the 2005–2014 period covering the 2008 global financial crisis (GFC) and the 2011 Tunisian revolution.

For the comparison between IBs and CBs, 11 hypotheses are formulated to distinguish between the two types of banks. The authors use a univariate analysis based on the multi-dimension figures investigation and a multivariate one based on the robust OLS technique for panel linear regression with mixed effects.

Bank-specific factors, dummy and dummy interacting variables indicate that there are differences between Islamic and conventional bank behavior. Both methods show that IBs are more liquid, more profitable and riskier than CBs. Post-2011 Tunisian revolution, small IBs (small CBs) are more (less) solvent, large IBs are more stable and both types of banks are more liquid, which explain why Tunisian governments have relay on bank system to cover budget deficits post-2011 revolution.

In investigating the feature of IBs and CBs from the Tunisian context, the authors take into account the effect of two abnormal events (2008 GFC and 2011 Tunisian revolution) on IBs through interaction variables.
