Abstract
Purpose
The present study aims to encompass the bidirectional magnetized flowing of a hybrid-nanofluid over an unsteady stretching device with the inclusion of thermal radiation and entropy generation. Brick-shaped nanoparticles (zinc-oxide and ceria) are suspended in water, serving as the base-fluid to observe the performance of the hybrid mixture. The Maxwell thermal conductivity relation is employed to link the thermophysical attributes of the hybrid mixture with the host liquid. Additionally, a heat source/sink term is incorporated in the energy balance to enhance the impact of the investigation. Both prescribed-surface-temperature (PST) and prescribed-heat-flux (PHF) conditions are applied to inspect the thermal performance of the hybrid nanofluid.
Design/methodology/approach
The transport equations in Cartesian configuration are transformed into ordinary differential equations (ODEs), and an efficient method, namely the Keller-Box method (KBM), is utilized to solve the transformed system. Postprocessing is conducted to visually represent the velocity profile, thermal distribution, skin-friction coefficients, Bejan number, Nusselt number and entropy generation function against the variations of the involved parameters.
Findings
It is observed that more entropy is generated due to the increases in temperature difference and radiation parameters. The Bejan number initially declines but then improves with higher estimations of unsteadiness and Hartmann number. Overall, the thermal performance of the system is developed for the PST scenario than the PHF scenario for different estimations of the involved constraints.
Originality/value
To the best of the authors' knowledge, no investigation has been reported yet that explains the bidirectional flow of a CeO2-ZnO/water hybrid nanofluid with the combined effects of prescribed thermal aspects (PST and PHF) and entropy generation.

Abstract
Purpose
This paper aims to examine rice farmers' selection of adaptation strategies to cope with and offset the effects of climate change and the determinants of those selections in Rajshahi, a severely drought-prone district of Bangladesh.
Design/methodology/approach
Farm-level micro data were obtained from 550 rice growers in the 2010-2011 farming season. A multinomial logit (MNL) model was utilised to assess the determinants of adaptation strategies practised by farmers in response to climate change.
Findings
Results from the MNL model indicate that gender, age, education of household heads, household assets, annual farm income, farm size, tenure status, farmer-to-farmer extension, access to credit, access to subsidy, and access to electricity, all affect farmers' selection of adaptation strategies for climate change.
Originality/value
This is the first study of its kind to analyse the determinants of adaptation strategies for climate change by farmers in drought-prone areas of Bangladesh. This study provides direction for policy makers in order to strengthen the adaptation strategies of farmers and guide policies accordingly. These strategies have the potential to minimise the adverse effects of climate change.

Abstract
Purpose
Recent academic work on leadership has focused largely on organizational leadership. This study takes a close look at political leadership, especially that given to popular movements, and delineates a new model of transformational leadership.
Design/methodology/approach
The current study borrows models from organizational leadership research and applies them to a specific case study to reveal critical concepts underlying transformational leadership. Application of these models to Bangladesh's founding father, Bangabandhu Sheikh Mujibur Rahman, during the two decades of the 1950 and 1960s, shows potential for a new flexible framework for transformational leadership with added significance on leader–follower relatedness, socio-historical context and charisma.
Findings
This study presents clear evidence on the nature of leadership in popular movements and using a specific case study elucidates that movements pick leaders who meet distinct criteria specific to the movement, including a vision that resounds with key follower-groups and prototypicality.
Research limitations/implications
This study presents a new lens under which political and popular leadership can be studied, focusing away from person, political party or rational choice and voting behavior-based ideas of political leadership.
Originality/value
The findings reveal the importance of seeking new ways to fit leadership theory with burgeoning social phenomenon.

This paper aims to systematically review studies of waqf accountability to conceptualise accountability in this unique setting.
Abstract
Purpose
This paper aims to systematically review studies of waqf accountability to conceptualise accountability in this unique setting.
Design/methodology/approach
This review followed the realist and meta-narrative evidence syntheses guidelines for meta-narrative review and used systematic searching for studies related to accountability in waqf institutions, based on the two main social sciences databases (Scopus and Web of Science). Thematic analysis was used to assess patterns regarding how researchers approached the concept of accountability in their studies, along with the context, the theories and the methods they used.
Findings
The number of research papers investigating the issue of waqf institutions’ accountability was severely limited in comparison to the growing literature on waqf institutions themselves. Existing research varies, with accountability practices understood through accounting, reporting and management perspectives, holistic accountability and studying various aspects antecedent to the achievement of accountability, such as governance, performance measurement and intellectual capital.
Originality/value
This study was conducted to fill the gap regarding a systematic review placing specific focus on accountability in the waqf institutional setting. The narrative from the review and suggestions for future research are provided to strengthen understanding of the current state of knowledge on accountability and direction, to enhance its usefulness in both theoretical building and practical improvement.

This study aims to determine the characteristics of waqf-based Islamic financial institution (IFI) and subsequently propose some waqf-based IFIs.
Abstract
Purpose
This study aims to determine the characteristics of waqf-based Islamic financial institution (IFI) and subsequently propose some waqf-based IFIs.
Design/methodology/approach
This study uses the Delphi method, combined with the Likert scale, to determine and validate the agreed characteristics of waqf-based IFI models. Subsequently, based on the agreed characteristics, the authors propose waqf-based IFI models.
Findings
The results show that there are 28 important characteristics of waqf-based IFI, which respondents agree on 24 characteristics with significant Kendall’s concordance or rater agreement (W). The type of waqf-based IFI could be a bank, venture capital or cooperative; the business orientation should be a combination of commercial-social, and it could be implemented in the national, community or micro level. Based on the agreed characteristics, the authors propose several waqf-based IFI, including integrated commercial-social waqf-based bank, integrated commercial-social waqf-based venture capital and integrated commercial-social waqf-based cooperative.
Research limitations/implications
Respondents of this study comprise experts and practitioners who reside in Indonesia so that the results of proposed waqf-based IFIs are most suitable to be implemented in Indonesia.
Practical implications
The conceptual framework and method used in this study could be applied to determine the characteristics of waqf-based IFI and propose the most suitable waqf-based IFI models in other countries.
Originality/value
This study starts with determining the essential characteristics of waqf-based IFI, which then be used to propose waqf-based IFI models.

This study examines whether students graduating from SSC-VOC perform better in diploma engineering programs.
Abstract
Purpose
This study examines whether students graduating from SSC-VOC perform better in diploma engineering programs.
Design/methodology/approach
This study uses quantitative and qualitative methods to examine how secondary school certificate-vocational (SSC-VOC) graduates perform in their subsequent vocational programs.
Findings
Despite having vocational training orientation, this study finds that graduates from SSC-VOC receive lower grades than their public counterparts by 0.109 cumulative grade points average (CGPA).
Social implications
Findings imply that policymakers should increase teachers' numbers, salaries and laboratory facilities. In addition, collaboration between SSC-VOC institutions and polytechnics would allow them to offer a quality engineering education. In such a way, technical and vocational education and training (TVET) programs prepare human resources to promote economic development and employment, expand production opportunities and improve employment quality.
Originality/value
This is the first piece of work conducted in Bangladesh that has examined the quality of VET graduates for furthering their studies. This study added value by providing some pragmatic suggestions for practical implications.

Abstract
Purpose
This paper attempts to review the corporate voluntary disclosure (CVD) from the theoretical perspective as well as propose a conceptual framework.
Design/methodology/approach
The researchers use structural literature review technique. The sample literature consisting of 55 articles was extracted from the Scopus database over the period of 2017–2021.
Findings
The literature observes that the legitimacy, agency and stakeholder theories are most applied in CVD related studies than the other theories. It is also revealed that researchers need to concentrate more studies on those theories of CVD that have been applied in a limited study such as neo-institutional, signaling, resource dependence, political economy and impression management theories.
Practical implications
The findings can help the understanding of parties such as practitioners', regulators and potential investors of the theories in CVD from a combined and comprehensive view.
Social implications
The results of the study offer new insights into the potential impact of organizational level and country level theories in CVD from different perspectives of developed and developing countries.
Originality/value
This study delivers an inclusive literature review of the current study approach on the theories of CVD and highlights some stimulating guidelines for future study.

Abstract
Purpose
The purpose of this study is to provide a profound understanding of the nature and extent of corporate social responsibility (CSR) disclosure in the annual report by the listed banking sectors in Bangladesh for examining the effect of board size and board composition on CSR disclosure.
Design/methodology/approach
The sample selected of all the 30 listed banks enlisted in the Dhaka Stock Exchange and the study used a content analysis approach. An ordinary least square regression model is fitted to the data for assessing the effect of independent variables on the total CSR disclosure score. An un-weighted approach has been used for this study.
Findings
The results of the study demonstrate that the extent of CSR disclosure of listed banks in Bangladesh varies from 11.11% to 73.33%, and on average, they report 45.37% and 43.44%, respectively. Moreover, the study observed a significant relationship between the proportion of female directors and CSR disclosure. Conversely, board size has been found no significant relationship with the CSR disclosure but the proportion of independent directors has been found a significant relationship with the CSR disclosure in the annual report by the listed banking sectors in Bangladesh.
Social implications
The study is expected to get a maximum scenario of CSR disclosure of banking sectors in Bangladesh. Government and other regulatory bodies can also get full information concerning CSR disclosure practices for formulating guidelines in this regard. If the Government of Bangladesh implicates the policies that the banks are to nominate a required number of female directors to boards, the consideration of the significant number of female directors and their power will be able to protect the interests of different stakeholder groups notably.
Originality/value
The study contributes to the CSR literature as it presents empirical evidence of the effects of board size and board composition on the CSR disclosure of banking sectors in developing countries such as Bangladesh.

Abstract
Purpose
This study examines, in relation to agency theory, the influence of corporate mechanism on the environmental reporting of banking businesses registered on the Dhaka Stock Exchange (DSE).
Design/methodology/approach
This study was carried out consuming an example of 150 annual reports from 30 banks for the period 2015–2019. Ordinary least squares (OLS) regression was used to investigate the inspiration of corporate governance on the range of inclusive environmental reporting.
Findings
The outcomes reveal that insider equity, board leadership structure, and presence of female directors are statistically significant, while board size and outside directors are insignificant. Furthermore, the results also indicate that the adoption of environmental disclosure among banking businesses in Bangladesh is extra motivated by an increase in the inside skills and moderately the outside acceptability weights. Additionally, there appears to be a supposed lack of stakeholder pressure for environmental disclosure.
Originality/value
The results show that the range of environmental reporting of banking businesses in Bangladesh is good, at an average of 53.90%. It concludes that corporate governance has a substantial inspiration on the range of environmental reporting of banking businesses in Bangladesh.
