This study aims to present an analysis on heat transfer attributes of fluid-particle interaction over a permeable elastic sheet. The fluid streaming on the sheet is Casson fluid (CF) with uniform distribution of dust particles.

The basic steady equations of the CF and dust phases are in the form of partial differential equations (PDEs) which are remodeled into ordinary ones with the aid of similarity transformations. In addition to analytical solution, numerical solution is obtained for the reduced coupled non-linear ordinary differential equations (ODEs) to validate the results.

The solution seems to be influenced by significant physical parameters such as CF parameter, magnetic parameter, suction parameter, fluid particle interaction parameter, Prandtl number, Eckert number and number density. The impact of these parameters on flow field and temperature for both fluid and dust phases is presented in the form of graphs and discussed in detail. The effect on skin friction coefficient and heat transfer rate is also presented in tabular form. It has been observed that an increase in the CF parameter curtails the fluid velocity as well as the particle velocity however enhances the heat transfer rate at the wall. Furthermore, comparison of the numerical and analytical solution is also made and found to be in excellent agreement.

Although the analysis of dusty fluid flow has been widely examined, however, the present study obtained both analytical and numerical results of power law temperature distribution in dusty Casson fluid under the influence of magnetic field which are new and original for such type of flow.

The purpose of this paper is to enable tourism management and strategic management students to evaluate and analyze tourism activities in the United Arab Emirates by TCA. Students will gain a comprehensive understanding of developing tourism in rural areas in the United Arab Emirates and to build up proper strategies. They will be able to perform the organization’s competitive standing using Porter’s Five competitive forces and analyze its business strategies as well. They will be able to analyze the current status of the organization using SWOT analysis and to design alternative strategies for the company using TOWS analysis.

The Department of Tourism and Culture – Abu Dhabi, also known as the TCA, is a governmental tourism authority in the Emirate of Abu Dhabi established 14 years ago as part of an economy-diversifying strategy for the non-oil era. The TCA is responsible of creating tourism activities to generate new tourists in Abu Dhabi, which will increase the revenue of the authority and as well increase the gross domestic product of the United Arab Emirates (UAE) economy. Tourism activities have been focused on Abu Dhabi City as is it considered the capital city of the UAE. However, other cities are also part of this strategy, e.g. Al Ain City, which is located in the eastern region of the Emirate of Abu Dhabi, and Al Dhafra City, which is located in the western region of the Emirate of Abu Dhabi, both of which lack the required infrastructure, population, and tourism activity, due in part at least to the fact that the TCA’s strategy plans have been focused on Abu Dhabi City. Sultan Al Mutawa Al Dhaheri (Al Dhaheri), the TCA’s Executive Director of Tourism, has been responsible for developing tourism in Al Ain City and Al Dhafra, but due to the current situation of the two cities regarding the low revenue growth (and the consequent lack of investors willing to invest) and no critical mass (i.e. a sufficient number of hotel rooms available), Al Dhaheri is facing a dilemma regarding achieving TCA strategy in Al Ain City and Al Dhafra City.

This case study will be useful for undergraduate and postgraduate level students majoring in Tourism and Hospitality Management, Business Administration and Strategic Management.

This study explores the determinants of value co-creation in the semi-government hospitals managed by Abu Dhabi Health Services Company (SEHA) and Mubadala in the United Arab Emirates (UAE).

The data were collected through a structured survey questionnaire from 1,000 patients attending different healthcare facilities in the UAE. To minimize errors, a pilot study was performed on 50 respondents. The study took the structural equation modelling (SEM) approach, adopting confirmatory factor analysis (CFA), reliability analysis and regression analysis to test the hypothesis.

This study confirms the substantial influence of communication, relationships, technological enhancement and customized service delivery on the co-creation of value. The findings also confirm in all respects the mediating role of trust in building value co-creation. This sheds light on the ways that healthcare facilities can enhance value co-creation and elevate healthcare services. Notably, the direct and indirect influence of knowing on trust is deemed insignificant in the context of value creation.

The main limitation of this research derives from its coverage of a subject that few empirical studies have targeted before; there were few models to draw on to demonstrate validity.

The research aids healthcare administrators in uncovering the dynamics of interactions between practitioners and patients, facilitating advances in the commitment to co-create value. The comprehensive insights into value co-creation contribute to the development of a versatile knowledge foundation, empowering proactive initiatives in the design of healthcare delivery models.

The uniqueness of this study lies in its expansion of previous research, making clear the effectiveness of various engagements that contribute to value co-creation in healthcare settings. It specifically focuses on semi-government hospitals managed by SEHA and Mubadala in the UAE.

Corporate social responsibility (CSR) has gained tremendous importance after several corporate scandals, financial crises and the rise of the hyper-competitive world. Firms must address multiple stakeholders’ interests to increase firm value. This study aims to investigate the effect of CSR on firm value. This study also examines the mediating role of enterprise risk management (ERM) and the moderating influence of corporate governance (CG) in this CSR-firm value relationship.

The sample of the study comprises 119 Pakistan Stock Exchange (PSX) listed firms and the study covers the period from 2010 to 2021. The corporate social responsibility performance has been quantified across five dimensions. These aspects are product, environment, employee relations, diversity and community. Four proxies i.e. strategy, operation, reporting and compliance, have been used to measure ERM. The governance quality of the sample companies was evaluated using the governance index, which included 29 governance provisions. The authors used the dynamic panel data technique (system-GMM) is used to achieve the objectives of the study. Furthermore, a firm’s engagement in CSR activities can also be measured through a multinational financial approach to check the robustness of the result.

Based on the regression analysis, the authors discovered that CSR was positively connected with firm value, validating the stakeholder view of CSR. Furthermore, following Baron and Kenny’s (1986) mediation technique, the findings confirm that ERM mediates this association. These results are robust by using the bootstrapping tests by Preacher and Hayes (2004). Furthermore, the result shows that corporate governance (CG) is positively connected with firm performance, and this relationship is strengthened in the presence of an effective governance system in the organization.

This study provides useful insights to regulators, investors and policymakers to consider CSR as a value-enhancing factor and encourage the development of enterprise risk management and compliance with CG mechanisms to improve firm value.

The presented analysis strengthens the existing CSR–firm value relationship by analyzing the mediating and moderating roles of ERM and CG, which have not yet been tested, particularly in the context of Pakistan.

The fundamental aim of the study is to investigate the implications of labor housing designs in Dubai, with a focus on courtyards and the governing building regulations, on daylight performance as an underlying factor impacting laborers’ indoor environmental quality. Several studies shed light on the subject of labor camps and labor migration in Dubai, but few have focused on the subject from the perspective of the environmental performance of these camps. A model that represents one of the labor camps was built using Rhinoceros 7.0 and Grasshopper software packages. Annual daylighting and glare simulations were carried out using the lighting modeling engine RADIANCE 5.0 in conjunction with the “ClimateStudio”.

The construction sector has emerged as a significant economic development driver, attracting a diverse labor force from a variety of countries to Dubai. As a result, Dubai authorities have implemented several measures to ensure the provision of suitable housing facilities for its labor force. These measures contribute to the reduction of energy costs in labor housing by encouraging the use of renewable energy. While several studies shed light on the subject of labor camps and labor migration in Dubai, few have focused on the subject from the perspective of the environmental performance of these camps.

The study provided statistical evidence that the current regulations governing courtyards in labor housing resulted in significant changes in daylight levels across different floor levels of the labor housing units. It is suggested that both 2:3 and 3:4 Court Width-to-Height ratios would further contribute to a more consistent daylight Illuminance with marginal statistical differences between floor levels (p > 0.05). The 3:4 ratio, on the other hand, offers a consistent distribution across all floor levels in the North and South with negligible variances, although weakly significant differences can be yet expected between the first and fourth floors in the East and West orientations (p < 0.05). The results of Annual Sunlight Exposure (ASE) suggest excessive solar incidence and a high probability of glare, which remains a problem that must be addressed under the governing building regulations.

This study could serve as a framework for analyzing and contrasting the findings of other studies on labor accommodation, notably in the Gulf Cooperation Council (GCC) countries. Such an approach has the potential to enhance living conditions in labor accommodations in Dubai and other areas. It is necessary to meet people' physical and psychological well-being while also addressing sustainability and regulatory compliance.

This scoping review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. A PubMed database search was performed for articles published between January 1 and November 29, 2023, using appropriate search terms; both authors performed screening and selection independently.

From the initial search results of 127 articles, 41 were eligible for final analysis. Articles were published in 34 journals. Editorials were the most common article type, with 15 (36.6%) articles. Authors originated from 27 countries, and authors from the USA contributed the most, with 14 (34.1%) articles. The most discussed topic was AI tools and writing capabilities in 19 (46.3%) articles. AI or ChatGPT was involved in manuscript preparation in 31 (75.6%) articles. None of the articles listed AI or ChatGPT as an author, and in 19 (46.3%) articles, the authors acknowledged utilizing AI or ChatGPT.

Researchers worldwide are concerned with AI or ChatGPT involvement in scientific research, specifically the writing process. The authors believe that precise and mature regulations will be developed soon by journals, publishers and editors, which will pave the way for the best usage of these tools.

This scoping review expressed data published on using AI or ChatGPT in various scientific research and writing aspects, besides alluding to the advantages, disadvantages and implications of their usage.

In the analysis of Third World economic and rural development, Malaysia represents an intriguing and somewhat special case. Many applaud the impressive growth registered since independence and particularly in recent years; as Vokes testifies, Malaysia is “one of the most successful cases of economic development in the Third World.” It has managed a structural transformation of its economic base from one relying on primary commodities to one in which manufacturers now play a central role; not denying the intermittent problem of fluctuating growth and uneven development.

The purpose of this study aims to examine the effect of fintech on pre- and post-financing credit risks faced by the Islamic banks.

This research uses primary data for fintech awareness and adoption and secondary data of various financial and economic variables from 2009 to 2021. It uses baseline regression to identify moderation of fintech controlling gross domestic products, size, return on assets and leverage. The findings are confirmed using robustness against key variable bias. It also uses a dynamic panel two-stage generalized method of moments for endogeneity.

The study finds that the fintech awareness and adoption are not the same across all Islamic countries. The Asia Pacific region is far ahead of the other two regions where Indonesia is ahead in terms of fintech awareness and adoption, and Malaysia is ahead in terms of reaping its benefits in credit risk management. Fintech affects prefinancing credit risk significantly more than postfinancing credit risk. Also, the study finds that Islamic banks suffer from the problem of “Adverse selection under Shariah compliance.”

This research invites regulators to introduce fintech in Islamic banks on war footing. Similar studies can be conducted on the role of other risks such as operational and market risks. Fintech will also help in improving the risk profile and stability of Islamic banks against systemic risks and financial crises.

This research has variety of originalities. First, it is the pioneering study that addresses the effect of fintech pre- and post-financing credit risks in Islamic banks. Second, it identifies “Adverse selection under Shariah compliance” for Islamic banks. Third, it helps identify how fintech can be useful in reducing credit risk that will help in reducing capital charge for regulatory capital.
