Abstract

Purpose

Effective performance of a direct ethanol fuel cell (FC) stack depends on the satisfactory operation of its individual cells where it is always challenging to manage the temperature gradient, water flow and distribution of reactants. In that, the design of the bipolar fuel flow path plate plays a vital role in achieving the aforementioned parameters. Further, the bipolar plates contribute 80% of the weight and 30%–40% of its total cost. Aim of this study is to enhance the efficiency of fuel to energy conversion and to minimize the overall cost of production.

Design/methodology/approach

The authors have specifically designed, simulated and fabricated a standard 2.5 × 2.5 cm2 active area proton exchange membrane (PEM) FC flow path plate to study the performance by varying the flow fields in a single ladder, double ladder and interdigitated and varying channel geometries, namely, half curve, triangle and rectangle.

Findings

Using the 3D PEMFC model and visualizing the physical and electrochemical processes occurring during the operation of the FCs resulted in a better-performing flow path plate design. It is fabricated by using additive manufacturing technology. In addition, the assembly of the full cell with the designed flow path plate shows about an 11.44% reduction in total weight, which has a significant bearing on its total cost as well as specific energy density in the stack cell.

Originality/value

Simultaneous optimization of multiple flow path parameters being carried out for better performance is the hallmark of this study which resulted in enhanced energy density and reduced cost of device production.

Abstract

Purpose

The purpose of this paper is to perform Shariah review of Brownian motion that is used for prediction of Islamic stock prices and their volatility.

Design/methodology/approach

It uses the Shariah compliant development model guidelines to review the Brownian motion and its applications.

Findings

The model of Brownian motion does not involve any variable that renders it non-Shariah compliant; neither all applications of Brownian motion are Shariah compliant. Because the model is based on stochastic properties that involve randomness, therefore the issue of gharar takes the utmost important to handle in the applications of the model. The results need to be analyzed strictly in accordance with the Shariah whether they create any element of gharar or uncertainty in case of expected price and volatility estimates.

Research limitations/implications

The research suffers from the limitation that it analyses only one model of physics, i.e. Brownian motion model from Shariah perspective.

Practical implications

The research opens an area for Shariah analysis of results generated from the application of advanced models of physics on matters related to Islamic financial markets.

Originality/value

The originality of this study stems from the fact that to the best of the authors’ knowledge, it is the first study that extends Shariah guidelines into Financial physics for making the foundations of Islamic econophysics.

Abstract

Purpose

The purpose of this paper is to investigate the determinants of Muslims’ attitude and intention towards Murabaha financing by considering religiosity as a moderator.

Design/methodology/approach

The data were collected through a survey of 373 Muslims in Afghanistan and were analysed using the partial least squares technique.

Findings

The results showed that social influence and religious obligation have a positive effect on attitude towards Murabaha financing. Furthermore, social influence and attitude have a positive effect on the intention to use Murabaha financing. Religiosity moderates negatively the impact of social influence on attitude towards Murabaha financing.

Practical implications

Managers and marketers of Islamic banks may benefit from the findings of this study, which provide insight into the factors that should be considered to promote Murabaha financing.

Originality/value

The findings contribute to the literature on Islamic financing products by demonstrating the drivers of attitude towards and intention to use Murabaha financing. The study also extends the literature by testing the moderating role of religiosity. Furthermore, the study extends the theory of reasoned action in the context of Islamic financing by introducing religious obligation as a potential driver of attitude and religiosity as a moderator.

Abstract

Purpose

Mega-infrastructure development plans pave the way for policies to upgrade the infrastructure, environmental management and different aspects of locals’ well-being. These developmental dynamics can positively affect rural tourism including heritage sites destinations. The quality of life of local people can be linked to this positive developmental change through long-term and sustainable economic revitalization projects. In terms of this process, developing large-scale infrastructure and incorporating tourism sustainability can improve the quality of life-related to different dimensions that are critical to the community's well-being. Therefore, researchers have attempted to address this issue.

Design/methodology/approach

Data were collected between September and October 2020. The study sample size was the residents of Zhabagly village, including Zhabagaly, Abaiyl and 115 Railway settlements. Moreover, the residents were older than 18 years. A systematic random sampling technique was utilised to reach the targeted sample size and the researchers received 243 responses from the locals. Structural equation modelling (SEM) was used for analysis.

Findings

The findings from the structural equation modelling suggest that sustainable tourism increases due to the positive effect of mega-infrastructure development and positively impacts the locals' quality of life. Notably, no direct effect of mega-infrastructure development on quality of life reveals the pivotal role of sustainable tourism. Therefore, during the COVID-19 period, the dimensions of sustainable tourism – economic, market, socio-cultural and environmental – played a role in securing the positive impact of mega-infrastructure development on the locals’ quality of life.

Research limitations/implications

This research highlighted the fact that when infrastructure projects are implemented to their full potential, they will generate sustainable tourism activities, provide eco-adventure activities, relax, treat signatories and boost the economy of all stakeholders. The study used AMOS to test the hypotheses. Qualitative research methods, including interviews with citizens, government officials and tourism managers, require further study.

Practical implications

The infrastructural development on a mega-scale means building an upscaling tourism ecosystem. This ecosystem is marked by the availability of drinking water, waste and energy management facilities that support the elevation of living material, community, health, safety and emotional well-being. It reflects the policy-level implications for future Belt and Road initiatives (BRIs). The tourism industry's resilience during COVID-19 has practical lessons for other industries.

Originality/value

Large-scale infrastructure construction must create favourable conditions for the rapid development of tourism. The availability of clean water, waste and energy management facilities contributes to the food production, social cohesion, physical and mental health and general well-being of the ecosystem. This is one of the few studies that used sustainable tourism as a mediator between the impact of large infrastructure projects and their impact on the quality of life of locals during the COVID-19 pandemic. Aksu-Zhabagly, a World Heritage Site in Kazakhstan, was the site of this field study.

Abstract

Purpose

This paper aims to explore the intention to adopt Islamic finance (ItIF) through the mediation of attitudes towards Islamic finance among microbusiness owners of Pakistan.

Design/methodology/approach

The study is co-relational and based on cross-sectional data. The authors gathered the data from microbusiness owners through a survey questionnaire. The authors used 236 valid cases to assume the outcomes.

Findings

The results through structural equation modeling reveal a significant positive effect of the perception of Shariah compliance (PoSC), knowledge of the Islamic financial system (KoIF), religious preferences (RP) and loyalty on ItIF. Furthermore, attitude towards Islamic finance (AtIF) is a potent factor in developing the relationship between PoSC, KoIF, RP, loyalty and ItIF.

Practical implications

The study’s findings would be helpful for planners and policymakers in developing policies that favourably enhance the attitudes and intentions among individuals towards Islamic financing. The results would inspire readers to go to Islamic finance and an interest-free financial system enriched with Shariah law or Islamic obligations. The study would provide implications for the financial institutions in Pakistan and the rest of the Muslim world.

Originality/value

The study offers an apparent thoughtfulness of the empirical evidence from microbusiness owners of Pakistan. The study would provide a plausible mediating contribution of AtIF.

Abstract

Purpose

Realistic data bank of aerodynamic and stability derivatives is still missing for hybrid buoyant aerial vehicles. Such vehicles take-off and land similar to an aircraft with their partial weight balanced by the aerostatic lift. The purpose of this paper is to use wind tunnel testing for a better understanding of the aerodynamic and static stability behavior of such vehicles.

Design/methodology/approach

The effect of wing on the aerodynamic and static stability characteristics of a clean configuration hybrid buoyant is analyzed. The free stream velocity is 20 m/s, and ranges of angle of attack and side slip angle are from −8° to 12° and ±16°, respectively. Data are corrected to account for the effect of strut interference and zero load condition. The maximum blockage of the model with respect to the cross-section area of the test section is about 2.7 per cent.

Findings

A hybrid model manufactured by using wood and metal is an optimum solution with less number of parts. The vehicle is statically, longitudinally and directionally stable. Wings designed to fulfill the partial requirement of lift contribute significantly to counter the huge moment generated by the voluminous hull for centre of gravity location ahead of the leading edge of the wing.

Research limitations/implications

There are number of manufacturing constraints for scaling down a model of a hybrid buoyant aerial vehicle configuration. Specially, the thickness of the wing limits the testing envelop of angle of attack and free stream velocity.

Practical implications

The data presented here are a preliminary guide for further work on larger size models. The data may also be used to build and perform flight tests on small full-scale instrumented models and to obtain flight dynamics data.

Originality/value

The estimated aerodynamic and stability derivatives and slopes can be utilized in future for multidisciplinary design.

Abstract

Purpose

The purpose of this study is to investigate the interplay between institutional investors' ownership (IIO), politically connected firms (POC) and sell-side analysts' stock recommendations (ASR).

Design/methodology/approach

This study employs ordinary least square (OLS) regression to test the hypotheses. The sample comprises 280 Malaysian public listed companies (PLC) and encompasses the 2008–2013 time frame (a total of 735 observations).

Findings

The results show a significant and positive link between IIO and ASR. In addition, a negative association is found between POC and ASR. Moreover, the POC weakens the positive relationship between the IIO and ASR.

Research limitations/implications

One important implication of this study is that political involvement in corporate decisions is a prominent characteristic of the Malaysian market, which can significantly affect the information environment and analysts' reactions.

Practical implications

The findings of this study provide useful empirical guidance to the regulators in evaluating the efficacy of recent regulatory initiatives. Investors may also gain useful insights from this study, specifically in recognising the crucial monitoring role played by institutional investors and how politically patronised firms are viewed unfavourably by equity analysts.

Originality/value

This study is one of the first to examine the joint influence of IIO and POC, on ASR.

Abstract

In the previous chapter, I introduced trauma-informed care as an approach to organisational change and a shift in culture to recognise that many employees and people attending services have past trauma experiences. In this chapter, I recast servant leadership (SL) as a trauma-informed leadership model that naturally operationalises some of the principles discussed in the TIA literature. The first section of this chapter addresses the societal need for a more ethical and moral leadership approach, before briefly outlining the prevalence of trauma experienced by service users and employees. The next section provides an overview and definition of SL in a general sense, before articulating a trauma-informed model of SL and its characteristics. Finally, some of the outcomes associated with SL are discussed with a key focus on how this approach operationalises the principle of psychological safety, trust and empowerment found in trauma-informed approaches, as they relate to employees.

Abstract

Purpose

Though Murabaha financing experienced substantial growth in several majority-Muslim countries, its market share in the Moroccan banking industry is still very narrow than other conventional banks’ instruments. The current research investigated the ability of an extended theory of planned behavior (TPB) framework to explain the main drivers of attitude and intention to use Murabaha financing among Moroccan households. The moderating effect of Islamic religiosity was also scrutinized.

Design/methodology/approach

Data were collected via a survey of 512 Moroccan consumers and analyzed using the partial least squares (PLS) technique.

Findings

First, attitude toward Islamic banking products is a key predictor of consumer intention to use Murabaha financing. At the same time, consumers’ attitudes are influenced by Islamic financial literacy, subjective norms, behavioral control and profit and loss sharing. Islamic religiosity was also found to positively moderate the link between attitudes towards Islamic banking (IB) and intention to use Murabaha financing, e.g. positive attitudes toward IB are more likely to convert into an intention to use Murabaha financing among Muslim consumers with higher levels of religiosity.

Managerial implications

To boost consumers’ intention to use Murabaha financing, Islamic bank managers should consider further investment in advertising to enhance consumers’ awareness about IB products. Islamic banks should also consider digital and social media marketing to increase consumers’ awareness about the products and spread a positive e-WOM with regards to their products. Our findings emphasize the importance of Islamic religiosity in shaping Muslim consumers’ intentions to use Murabaha financing. Islamic banks ought to make sure that Murabaha financing contracts are strictly adherent to and compliant with Shari’ah principles. They should also train their frontline employees on Islamic financing activities so that they can effectively respond to the queries and questions of Murabaha potential consumers.

Originality/value

The study findings contribute to the IB literature by demystifying the key factors shaping Muslim consumers’ intentions to use Murabaha financing. The study also extends the literature by emphasizing Islamic religiosity as a basis for Muslim consumers’ behavior in the context of IB. To the best of our knowledge, this study is among the first to empirically investigate Muslim consumers’ intention to use Murabaha financing in North Africa and the Arab countries.

Abstract

Purpose

This research aims to analyses the structural model of customers’ intention towards reputable and accountable Islamic finance, explained through Meta-Analysis Structural Equation Modelling (MASEM) with the Theory of Planned Behaviour approach and extended variables.

Design/methodology/approach

This study used MASEM to examine the factors systematically influencing behavioural intentions within Islamic finance. By synthesising 89 existing studies, the study identified key variables and their relationships, providing a comprehensive understanding of the underlying mechanisms. A rigorous methodology involving article selection, data extraction and statistical analysis enabled the development of a robust conceptual framework.

Findings

This study underscores the significant impact of subjective norms and perceived behavioural control on the intention to adopt Islamic finance, mediated by customer attitude. Religiosity, customer awareness and knowledge influence the intention to adopt Islamic finance products, with the Islamic financial institution's reputation and customer attitude serving as mediating variables.

Originality/value

This research novelty examines Islamic finance accounting, reporting and financial accountability, primarily focusing on customers’ perceived intentions towards Islamic financial practices.
