The purpose of this paper is to study the particle shape effects on Marangoni convection boundary layer flow of a nanofluid. The paper aims to discuss diverse issues befell for the said model.

The work undertaken is a blend of numerical and analytical studies. Analytical and numerical solutions of nonlinear coupled equations are developed by means of Mathematica package BVPh 2.0 based on the homotopy analysis method.

The velocity of nanofluid decreases by increasing particle volume friction and similarity parameters. With the increase in particle volume friction and similarity parameter, temperature profile is correspondingly enhanced and decline. The lowest velocity and highest temperature of nanofluid is cause by needle- and disc-shaped particle. Consequence for interface velocity and the surface temperature gradient are perceived by numeric set of results. It is found that the interface velocity is declined by increasing particle volume friction and volume concentration of ethylene glycol in the water. The minimum interface velocity is seen by needle-shaped particle and 30 percent concentrations of ethylene glycol. With increase in volume friction and size of particle, the behaviors of surface temperature gradient are found decreasing and increasing function, respectively. The maximum heat transfer rate at the surface is achieved when we chose sphere nanoparticles and 90 percent concentrations of ethylene glycol as compared to other shapes and concentrations.

This model is investigated for the first time, as the authors know.

The purpose of this paper is to study the effects of natural convection heat transfer in a cold outer circular enclosure containing a hot inner elliptic circular cylinder. The fluid in the enclosure is Cu-water nanofluid. The main emphasis is to find the numerical treatment for the said mathematical model. The effects of Rayleigh number, inclined angle of elliptic inner cylinder, effective of thermal conductivity and viscosity of nanofluid, volume fraction of nanoparticles on the flow and heat transfer characteristics have been examined.

A very effective and higher order numerical scheme Control Volume-based Finite Element Method (CVFEM) is used to solve the resulting coupled equations. The numerical investigation is carried out for different governing parameters namely; the Rayleigh number, nanoparticle volume fraction and inclined angle of elliptic inner cylinder. The effective thermal conductivity and viscosity of nanofluid are calculated using the Maxwell-Garnetts (MG) and Brinkman models, respectively.

The results reveal that Nusselt number increases with an increase of nanoparticle volume fraction, Rayleigh numbers and inclination angle. Also it can be found that increasing Rayleigh number leads to a decrease in heat transfer enhancement. For high Rayleigh number the minimum heat transfer enhancement ratio occurs at.

To the best of the authors’ knowledge, no such analysis is available in the literature which can describe the natural convection heat transfer in a nanofluid filled enclosure with elliptic inner cylinder by means of CVFEM.

The transformation of coronavirus disease (COVID-19) from a regional health crisis in a Chinese city to a global pandemic has caused severe damage not only to the natural and economic lives of human beings but also to the financial markets. The rapidly pervading and daunting consequences of COVID-19 spread have plummeted the stock markets to their lowest levels in many decades especially in South Asia. This concern motivates us to investigate the stock markets’ response to the COVID-19 pandemic in four South Asian countries: Bangladesh, India, Pakistan and Sri Lanka. This study aims to investigate the causal impact of the number of confirmed COVID-19 cases on stock market returns using panel data of the countries stated above.

This study collects and analyzes the daily data on COVID-19 spread and stock market return over the period May 28, 2020 to October 01, 2020. Using Dumitrescu and Hurlin panel Granger non-causality test, the empirical results demonstrate that the COVID-19 spread measured through its daily confirmed cases in a country significantly induces stock market return. This paper cross-validates the results using the pairwise Granger causality test.

The empirical results suggest unidirectional causality from COVID-19 to stock market returns, indicating that the spread of COVID-19 has a dominant short-term influence on the stock movements. To the best of the knowledge, this study provides the first empirical insights into the impact of COVID-19 on the stock markets of selected South Asian countries taking the cross-sectional dependence into account. The results are also in line with the findings of other existing literature on COVID-19. Moreover, the results are robust across the two tests used in this study.

The findings are equally insightful to the fund managers and investors in South Asian countries. Taking into account the possible impact of COVID-19 on stock markets’ returns, investors can design their optimal portfolios more effectively. This study has another important implication in the sense that the impact of COVID-19 on the stock markets of South Asian countries may have spillover effects on other developing or even developed countries.

Few studies only focus on halal cosmetics, although several previous studies have examined halal food and beverages. This study aims to explore the relationship between knowledge, emotional attachment and religiosity on purchase intention, mediated by satisfaction and brand trust. This study stems from the theory of reasoned action (TRA), which merges the knowledge, emotional attachment, religiosity and purchase intention of halal cosmetics.

The researchers distributed online questionnaires to respondents via Google Form using social media (Instagram)/messaging application (WhatsApp). The respondents were Indonesian and Malaysian millennial Muslims. The sampling technique used was purposive sampling. A total of 528 respondents were involved, consisting of 335 Indonesians and 193 Malaysians. However, data for 381 respondents were successfully screened for normality, outliers and multicollinearity. Furthermore, the data was used for examining the hypotheses proposed.

The results for Indonesian and Malaysian samples showed that there is a significant positive effect of knowledge, emotional attachments and religiosity on satisfaction and brand trust. But the Indonesia sample showed that there is no significant effect of religiosity on satisfaction. For Indonesia, there is a positive significant mediating role of satisfaction on purchasing intention. For Malaysia, there is no significant mediating role of satisfaction on purchasing intention. For Indonesia and Malaysia, there are positive significant mediating role of brand trust on purchasing intention.

The study compared consumers of the millennial generation in Indonesia and Malaysia with limited samples. For future research, it is suggested to exploring and combining non-Muslims and Muslims in the millennial generation and testing it in more than two countries.

The study provides an accurate understanding of the relationships proposed, such as knowledge, emotional attachment and religiosity, on satisfaction, brand trust and purchasing intention of millennial Muslim woman consumers in Indonesia and Malaysia, because the millennial Muslim woman consumers in Indonesia and Malaysia had the same behavioral characteristics: Muslim consumers and product characteristics.

The study of halal cosmetics can provide a spiritual commitment for Muslims, who consciously prefer socio-religious values in choosing cosmetic products. Therefore, the halal label of the product is also a reason for social and religious values to increase the social awareness of the Muslim millennial generation in Malaysia and Indonesia.

This research discusses the antecedents and consequences of satisfaction and brand trust on the purchasing intention of halal cosmetics. The response of Muslim consumers to halal cosmetics has not been widely studied in Indonesia and Malaysia. Meanwhile, in Indonesia, the halal label on all products has recently been made mandatory by the Indonesian Ulema Council. Therefore, this research offers insights into the attitudes of Muslim consumers towards halal cosmetics products.

This paper aims to examine the effect of gamification training on employee task performance within the context of intellectual, social and affective (ISA) employee engagement in India. The use of gamification in training as a possible precursor to increased employee engagement is a fascinating research topic, especially as employee engagement is becoming an increasingly important factor in workplace success.

To achieve the aim of this study, 300 responses were obtained from employees in an Indian company using online surveys to quantitatively assess levels of employee engagement and task performance. Statistical tests like SPSS 20.0 and Smart PLS 3.0 were run on the collected data to see if gamification training led to significantly higher levels of employee engagement and if this engagement had an effect on task performance.

Result tells that social and affective engagement mediates the relationship between gamification training and employee task performance in gamification-using organisations, relative to intellectual engagement. As social and affective engagement has considerable positive effects on employee job performance and gamification training, gamification training is a critical approach for organisations to implement to increase employee engagement and, consequently, performance.

Using an innovative variable of employee engagement – specifically, ISA employee engagement – the authors have sought to establish a mediating link between gamification and employee task performance. Therefore, the study’s designs have practical value for organisations because they incorporate the ISA engagement scale into a game-based learning environment.

This study empirically examines the impact of motivation, transformational leadership and involvement in strategic planning (SP) on academic staff performance at higher education institutions (HEIs). It also examines how academics' involvement in SP mediates the associations between motivation, transformational leadership and performance.

This article conducted a quantitative approach based on a self-administered survey. Partial least squares structural equation modeling (PLS-SEM) was applied to analyze the data gathered from 192 faculty members at governmental HEIs in Oman.

The results indicated that academic staff motivation has a significant and positive impact on their involvement in SP and performance in HEIs. It is also revealed that employee involvement in SP activities is significantly affected by transformational leadership, while the latter does not affect academic staff performance. There is also a significant association between academic staff involvement in SP and their performance. Moreover, the relationships between motivation, transformational leadership and performance are fully mediated by academic staff involvement in SP at HEIs.

The current empirical work is one of the few endeavors to develop an integrated structural model to investigate how faculty members' performance could be affected by motivation, transformational leadership and involvement in SP. Furthermore, it is considered one of the first attempts to explore the intervening role of academic staff involvement in the SP process in the connections between motivation, transformational leadership and performance within the HEI realm.

This study aims to examine the impact of stakeholder pressure on Islamic banks’ corporate social responsibility (CSR) practices and financial performance.

A close-ended questionnaire was collected from 282 Islamic bank’s branch managers. Partial least square structural equation modeling was used to test the hypothesized model. Both measurement and structural models were found to be fit for this research.

Results indicate that all components of stakeholder pressure (management, client, competitor, Sharia advisory board and community) have a significant positive impact on Islamic CSR. The findings of this study further revealed that Islamic CSR is a significant predictor of bank’s financial performance. Based on the present empirical results, this study suggests that Islamic bank managers should develop the best CSR practices to gain a competitive advantage and sustainable financial performance.

Overall, this study contributes significantly to the Islamic bank CSR literature. However, to the best of the authors’ knowledge, few studies have been conducted to establish a link between firm performance and CSR in Islamic banks using a comprehensive model of stakeholder pressure.

The purpose of this study is to identify the effectiveness of risk management and corporate governance (CG) practices followed in Islamic banks (IBs) of Gulf Cooperation Council (GCC) countries. Hence, they are considered as critical performance indicators for financial institutions and IBs. Though the IBs are growing, there are still challenges associated with their operations because of Shariah noncompliance risks, governance, capital adequacy ratio and other risks.

This study uses a mixed-method approach, gathering qualitative data from senior risk managers of chosen IBs via semi-structured interviews and quantitative data from selected IBs financial reports using capital IQ resources. The information was gathered for a considerable time (2013–2019), and the CAMELS rating system was used to analyze it.

The results showed that GCC IBs manage their business risks well through effective CG except in certain areas like asset quality management and liquidity.

The result of this study can provide support to the banks’ top management, chief executives, regulators and government, in all practices related to risk assessment, management and mitigation.

This study contributes to the existing knowledge in risk management and CG practices. Furthermore, this study is a new attempt in knowing the risk management and CG practices followed in IBs in GCC countries using the mixed-method approach.

The purpose of this study is to empirically examine the determinants and outcomes of Islamic corporate social responsibility (ICSR) adoption in Islamic bank branches in Pakistan. The research framework examines the influence of stakeholder’s pressure on ICSR adoption. It also analyses the relationship between ICSR adoption and intangible outcomes achieved by the Islamic bank branch.

A total of 400 questionnaires were distributed through a mail survey to Islamic bank branches in Pakistan. The respondents of the study were the branch manager of Islamic bank branches in Pakistan. A simple random sampling technique was used and resulted in the collection of 293 usable questionnaires. SMART PLS was used to statistically analyse the data using partial least squares structural equation modelling approach. The measurement and structural models were analysed.

The results indicate a significant and positive relationship between Shariah supervisory board pressure, competitor pressure and ICSR adoption in Islamic bank branches. A moderate strength positive relationship was found out between top management pressure and ICSR adoption. Results reveal that customer pressure and community pressure have an insignificant influence on ICSR adoption. Data analysis shows that the adoption of ICSR practices have a significant and positive influence on an Islamic bank branch’s Intangible outcomes.

The sample size was relatively small because of the limited time duration.

The construct of ICSR has not been extensively researched upon especially through empirical studies. Limited research exists in the area of factors than can influence Islamic bank branches to adopt ICSR practices and currently no empirical research has focussed on the intangible outcomes that can be achieved through ICSR adoption by an Islamic bank branch. The limited study exists in the Pakistan context as well, which is a rapidly growing Islamic banking industry.

In line with the general purpose mentioned, this paper aims to determine the impact of the Islamic work ethic (IWE) on job satisfaction and organizational commitment among the employees of Bank Maskan by examining the mediating role of intrinsic motivation.

Analysis of data obtained from 220 questionnaires related to research variables with AMOS software shows a positive and significant relationship between IWE and job satisfaction and organizational commitment with the mediating role of intrinsic motivation.

The findings revealed a direct effect of IWE on job satisfaction, but there was no direct significant relationship between this variable and organizational commitment. Also, intrinsic motivation plays a partial and completely mediatory role in the relationship between IWE and job satisfaction and between IWE and organizational commitment.

The impact of participation in strategic planning on managers’ creation of budgetary slack: The mediating role of autonomous motivation and affective organizational commitment.

As the nature of bank employees’ work is such that it confronts them with numerous ethical choices, the adherence to ethical standards, particularly IWE, can greatly affect their enthusiasm and, as a result, their satisfaction and organizational commitment.
