Abstract
Purpose
Informational use of social media facilitates political engagement. Yet, there is also evidence of the perils of frequent political engagement in misinformation propagation. This study aims to examine the association between online political engagement, perceived exposure to misinformation, individuals’ cognitive characteristics and misinformation sharing.
Design/methodology/approach
In this paper, online surveys were conducted in Kenya, Nigeria and South Africa (Study 1) and the United States (Study 2).
Findings
Study 1 finds that online political engagement is positively associated with perceived exposure to and sharing of misinformation. Mediation analyses suggest that the relationship between online political engagement and misinformation sharing is mediated by perceived exposure to misinformation. Further, the likelihood of sharing misinformation is found to increase at higher levels of online political engagement, but those with low need for cognition (NFC) are more vulnerable to such sharing. Study 2 explores cognitive ability in place of NFC. The results follow similar patterns as Study 1 – online political engagement is linked to misinformation sharing via higher perceived exposure to misinformation. The authors also find that the tendency to share misinformation increases with frequent exposure to misinformation but those with lower cognitive ability are more prone to such sharing.
Originality/value
In both contexts, the data show that perceived exposure to misinformation mediates the relationship between online political engagement and misinformation sharing and those with low NFC and cognitive ability are more vulnerable. Overall, the findings offer insight into the mechanisms of political engagement and sharing misinformation.

Abstract
Purpose
The purpose of this paper is to create a nuanced understanding of the barriers women high-tech professionals face in Bangladesh. The main aim is to identify the extent to which these barriers are common across different contexts and to explore the barriers that are unique and situated in the local socio-cultural context.
Design/methodology/approach
In-depth interviews with high-tech professionals were conducted to identify and explore the barriers.
Findings
Although some of the barriers are common across different contexts, most of the barriers women professionals face arise due to the interaction between situated socio-cultural practices and gender. The dynamics of socio-cultural and patriarchal norms reinforce gender biases and gendered practices that afford men with greater control over resources and systematically limit women’s access to opportunities.
Research limitations/implications
The study recruited 35 participants using snowball sampling. From a methodological perspective, future research could benefit from recruiting a larger, more varied sample using random sampling.
Practical implications
Women experience barriers due to both internal organizational features and external contextual barriers. The findings suggest that some of these barriers can be removed through governmental and organizational policies and through appropriate intervention strategies delivered in partnership with governmental and non-governmental organizations.
Originality/value
The study makes a unique contribution by using a macro-social lens to analyze the meso-organizational practices and micro-individual phenomena thereby providing a holistic view of the barriers faced by women professionals in Bangladesh.

Abstract
Purpose
Environmental and operational restrictions increasingly drive modern aircraft design due to the growing impact of global warming on the ecology. Regulations and industrial measures are being introduced to make air traffic greener, including restrictions and environmental targets for aircraft design that increase aerodynamic efficiency. This study aims to maximize aerodynamic efficiency by identifying optimal values for sweep angle, taper ratio, twist angle and wing incidence angle parameters in wing design while keeping wing area and span constant.
Design/methodology/approach
Finding optimal wing values by using gradient-based and evolutionary algorithm methods is very time-consuming. Therefore, an artificial neural network-based surrogate model was developed. Computational fluid dynamics (CFD) analyses were carried out by using Reynolds-averaged Navier–Stokes equations to create a properly trained data set using a feedforward neural network.
Findings
The results showed how a wing could be optimized by using a CFD-based surrogate model. The two optimum results obtained resulted in increases of 10.7397% and 10.65% in the aerodynamic efficiency of the baseline design ONERA M6 wing.
Originality/value
The originality of this study lies in the combination of sweep angle, taper ratio, twist angle and wing incidence angle within the scope of wing optimization calculations.

Abstract
Purpose
The purpose of this study is to conceptualise the relationship between information disclosure and Waqif commitment, taking into consideration the role of level of trust (mediator variable) and communication and type of payment (moderator variables).
Design/methodology/approach
The conceptual framework is developed from the theory of social exchange (mediated philanthropy model) and selected previous literature concerning commitment.
Findings
According to previous empirical research, a conceptual framework was developed to facilitate further analysis in the study. Nine propositions were raised in this paper where the factor of communication and payment method is proposed to no longer the factor that determined commitment but as moderator. There is five antecedent of information disclosure proposed, which is basic information, financial information, non-financial information, future information and governance information. Also, trust is offered to be the mediator variable between information disclosure and Waqf commitment.
Research limitations/implications
By realising many factors that may influence the commitment of waqf such as demonstrable utility, emotional utility and familial utility, this study only focusses on the effect of information disclosure.
Practical implications
This paper provides an opportunity for further empirical studies to prove the relationship between information disclosure and Waqf commitment. This paper also brought opportunities to investigate both conceptually and empirically, other factors that could affect Waqf commitment.
Originality/value
To the best of the author’s knowledge, few studies have been done concerning donors commitment. While there are none yet, the research examined Waqf commitment. The originality value of this study is that there is a gap in knowledge regarding the analysis of Waqf commitment, the level of trust among waqif is the information that Waqf expected, the preferred communication between Mutawalli and Waqf and type of payment that Waqf favoured. This study is believed to be a novel based on the framework developed.

Abstract
Purpose
This paper provides a critical assessment of Indonesia’s pioneering initiative in issuing cash waqf-linked sukuk (CWLS), a hybrid government sukuk integrated with Islamic endowment funds (waqf). Focused on addressing urgent health-care and essential expenditures, this study aims to evaluate the features and performance of CWLS sales.
Design/methodology/approach
Using a literature review and in-depth interviews, this study comprehensively analyzes CWLS from multiple perspectives.
Findings
The research indicates that CWLS effectively mobilizes public funds, benefiting the government by supporting essential needs and enhancing waqf management in Indonesia. Moreover, it significantly improves the quality of life through social projects financed by CWLS returns.
Practical implications
The study offers actionable recommendations for enhancing CWLS performance in Indonesia and serves as a suggestion for other governments considering similar financial instruments.
Social implications
As a socially oriented financial tool, CWLS emerges as a pivotal strategy for enhancing national waqf management and promoting equitable wealth distribution.
Originality/value
This study represents the first critical assessment of CWLS in Indonesia, advancing theory by integrating Islamic finance principles with governmental fiscal policies through innovative sukuk structures. It contributes to the distributive justice theory by demonstrating how CWLS operationalizes fairness and equity in resource allocation.

Abstract
Purpose
Combustion of fuel with oxidizer inside a combustion chamber of an internal combustion engine forms inevitable oxides of nitrogen (NOx) due to high temperature at different locations of the combustion chamber. This study aims to quantify NOx formed inside the combustion chamber using two fuels, a conventional diesel (n-heptane) and a biodiesel (methyl oleate).
Design/methodology/approach
This research uses a computational fluid dynamics simulation of chemically reacting fluid flow to quantify and compare oxides of nitrogen (NOx) in a compression ignition (CI) engine. The study expends species transport model of ANSYS FLUENT. The simulation model has provided the temperature profile inside the combustion chamber, which is subsequently used to calculate NOx using the NOx model. The simulation uses a single component hydrocarbon and oxygenated hydrocarbon to represent fuels; for instance, it uses n-heptane (C7H16) for diesel and methyl-oleate (C19H36O2) for biodiesel. A stoichiometric air–fuel mixture is used for both fuels. The simulation runs a single cylinder CI engine of 650 cm3 swept volume with inlet and exhaust valves closed.
Findings
The pattern for variation of velocity, an important flow parameter, which affects combustion and subsequently oxides of nitrogen (NOx) formation at different piston locations, is similar for the two fuels. The variations of in-cylinder temperature and NOx formation with crank angles have similar patterns for the fuels, diesel and biodiesel. However, the numerical values of in-cylinder temperature and mass fraction of NOx are different. The volume averaged static peak temperatures are 1,013 K in case of diesel and 1,121 K in case of biodiesel, while the mass averaged mass fractions of NOx are 15 ppm for diesel and 141 ppm for biodiesel. The temperature rise after combustion is more in case of biodiesel, which augments the oxides of nitrogen formation. A new parameter, relative mass fraction of NOx, yields 28% lower value for biodiesel than for diesel.
Originality/value
This work uses a new concept of simulating simple chemical reacting system model to quantify oxides of NOx using single component fuels. Simplification has captured required fluid flow data to analyse NOx emission from CI engine while reducing computational time and expensive experimental tests.

Abstract
Purpose
India's Muslim women (MW) face significant underrepresentation within the government and commercial sectors, rendering them virtually invisible in the job market. This underrepresentation is compounded by the double stigma of being both Muslim and female. As a result, this study aims to address this critical issue by looking into MW's intention to work in the industry of tourism and hospitality (T&H).
Design/methodology/approach
A survey was conducted online to gather data and 404 of the responses met the requirements for selection. The research model was empirically assessed by applying structural equation modelling. The data collection phase spanned from August 11, 2023, to November 10, 2023.
Findings
The study's findings demonstrate the effectiveness of the extended theory of planned behaviour in providing a robust model for analysing MW's intentions to participate in the T&H industry.
Research limitations/implications
This research discloses inclusive policies, reduces discrimination, empowers women in the workforce, improves educational opportunities, promotes cultural sensitivity and fosters inclusive leadership in the T&H industry, focusing on MW career intentions, to achieve Sustainable Development Goal 5 (gender equality).
Originality/value
The importance of this study is contingent upon its ability to inform policymakers in academia and the T&H sector. By recognising and addressing the barriers faced by MW, it has the potential to foster a workplace environment that promotes equality and eliminates discrimination, ultimately improving the image of the T&H industry and harnessing the untapped potential of these women in India.

Abstract
Purpose
This research examines the influence of the learning environment and students' attitudes towards choosing an accounting career mediated by intention to enhance the current knowledge.
Design/methodology/approach
The online survey is adopted to test the research model of this research. There are 503 useable responses collected with the effective response rate of 72 per cent. Data analysis and hypothesis testing use Partial Least Square as part of the Structural Equation Modelling technique.
Findings
The results of this research indicate that accounting students possess positive attitude both towards the intention to enhance the current knowledge and choosing their accounting career. The learning environment includes educators and friends who give significant influence on students' intention. Besides, current knowledge enhancement is also discovered to be able to mediate the link between attitude, learning environment and intention to choose accounting career.
Research limitations/implications
Different generations may generate either different perception or different orientation in choosing accounting career. Therefore, future research can consider wider coverage and more updated object.
Practical implications
Findings of this research suggest that periodic improvement and renewal are necessary to administer to create an optimum learning environment, in term of teachers' capacity, teaching materials and supporting social environment.
Originality/value
This research contributes to any research related to attitudes towards choosing an accounting career. This study is the leading study that combines students' attitudes, learning environment, current knowledge enhancement, and career choice in one single model.

Abstract
Purpose
To analyse Sukuk Prihatin (SP), the first-ever retail digital sukuk issued by the Government of Malaysia in the midst of the COVID-19 pandemic, as part of the national economic recovery plan. The issuance of SP was oversubscribed, even upsized, resulting in the government announcing its intention to issue similar types of sukuk in the future. In light of this, the purpose of this study is to understand the motivation for retail investors to invest in SP.
Design/methodology/approach
The purposive sampling method was applied via a self-administered survey, while the cross-sectional data were empirically tested using the SmartPLS 3.2.9 structural equation modelling. An integrated model of the theory of planned behaviour and social cognitive theories was used in determining investors’ intention to invest in SP.
Findings
The findings of this research revealed that attitude (ATT) towards SP investment (SPI), social norms (SN), perceived control (PBC) regarding SPI, sukuk features (SF), tax incentives (TI) and the spirit of unity and brotherhood (SUB) were significant determinants of investors’ willingness to invest in SP. This research also provided evidence for significant national pride-moderated interactions of ATT, SN, PBC, SF, TI and digitisation on investment intention.
Practical implications
The outcome of this study could assist governments and policymakers to structure sukuk and other debt-based capital market products to attract retail investors who would be willing to invest in the development of the nation in the midst of a crisis.
Originality/value
This study is the first of its kind to investigate various relevant predictors, which have been derived from behavioural, contextual and motivational perspectives. These predictors could influence investors’ perceptions of an innovative sukuk like SP, which was issued in the midst of a pandemic. The value of this study is its possible use by governments and policymakers to further develop debt-based capital market products that have the dual function of an investment vehicle and a source of funds for the economic recovery of a nation.
