This study aims to assess the prevalence of burnout among undergraduate medical and health science students and to identify the factors associated with its development.

A cross-sectional study was conducted involving students from Ras Al Khaimah Medical and Health Science University. The Maslach Burnout Inventory-Student Survey was used to evaluate three subscales of burnout. Ethical considerations were met, and informed written consent was obtained from participants. Bivariate and multiple logistic regression analyses were conducted to examine the relationship between demographic, personal and school environment factors and burnout.

Out of 453 students surveyed, the majority were females (74.8%) aged 18–20 years (60%). Significant levels of burnout were reported, with emotional exhaustion, depersonalization and reduced personal accomplishment affecting over half of the participants (69%). Factors such as being in the clinical years, long-distance commuting challenges and involuntary college selection were identified as predictors of burnout.

While the study provides valuable insights, limitations may include the specific context of the university and potential biases in self-reported data.

The findings underscore the importance of raising awareness, maintaining work-life balance and implementing coping strategies to support student well-being and foster a positive learning environment. Suggestions include time management and seeking guidance from mentors or mental health professionals.

This study contributes to the understanding of burnout among medical and health science students, especially within the unique context of the United Arab Emirates, given the convergence of students from diverse nationalities and cultural backgrounds.

The Arab world has witnessed a remarkable surge in the growth of its tourism and hospitality (T&H) industry, positioning it as a vital cornerstone for sustainable development. However, an exclusive bibliometric analysis of T&H research contributed by the Arab world has not yet been conducted in the past 30 years, that is, 1993–2022. Therefore, the purpose of this study is to provide a first-of-its-kind bibliometric assessment and visualization of T&H research produced by the Arab world spanning from 1993 to 2022.

A comprehensive collection of 1,327 scientific publications related to T&H research contributed by the Arab world was acquired from the Web of Science Core Collection database. To perform a large-scale bibliometric analysis, encompassing performance analysis, science mapping and network analysis, this study used state-of-the-art analytical tools, namely, Bibliometrix package of R Studio and VOSviewer.

The findings of this study show that the Arab world’s research on T&H has significantly surged since COVID-19, contributing nearly half (50.56%) of the total literature in the T&H domain between 2020 and 2022. Elshaer IA (Suez Canal University, Egypt) emerged as the most productive author, while Nusair K (Sultan Qaboos University, Oman) was identified as the most impactful author in the T&H domain in the Arab world. The most productive journal was found to be Sustainability (MDPI), while Tourism Management (Elsevier) was identified as the most impactful journal in the field of T&H. Furthermore, the thematic analysis highlights that research themes in T&H are not static but rather constantly evolving in response to dynamic changes in the industry, such as emerging trends, shifts in tourist preferences and the impact of global events like the COVID-19 pandemic.

To the best of the authors’ knowledge, this is the first bibliometric analysis of T&H research contributed by the Arab world, specifically covering the period from 1993 to 2022. This study's findings can inform the development of strategies and policies for the sustainable and competitive growth of the T&H industry in the Arab world. This study highlights the importance of continued research and collaboration among industry professionals, academics and policymakers to promote innovation and drive positive change in the T&H sector in the Arab world.

阿拉伯世界已经目睹了其旅游和酒店（T&H）行业增长的显著激增, 将其定位为可持续发展的重要基石。然而, 在过去30年中, 即1993年至2022年, 尚未进行关于阿拉伯世界贡献的T&H研究的专属文献计量分析。因此, 这项研究代表了提供阿拉伯世界自1993年至2022年间T&H研究的首创性文献计量评估和可视化的先驱努力。

Este estudio resalta la importancia de la investigación continua y la colaboración entre profesionales de la industria, académicos y responsables políticos para promover la innovación y generar un cambio positivo en el sector de T&H en el mundo árabe.

Food waste (FW) is a significant problem in the hospitality sector worldwide. The Covid-19 pandemic has imposed a health protocol on the hospitality sector to protect the customers and the community. This paper aims to evince a new understanding of the tourist city during the Covid-19 pandemic by exploring the effects of the new health protocol on FW management at the consumption stage in the hospitality sector in Dubai.

In this study, the authors use a scale assessment method and a survey distributed to 202 tables in 35 restaurants offering open buffet catering in Dubai.

The paper’s findings provide evidence that: first, the tourist city has faced substantial changes during the pandemic as the new health protocol imposed by the Covid-19 circumstances has mitigated the waste of food in the open buffet services. Second, the highest waste has been observed for vegetables, followed by grains (especially rice) and bread. The lowest waste has been observed for meat and fruits. Third, FW per table varies considerably by consumer groups. The FW quantity of residents is significantly higher than that of tourists. Family gathering tables with an essential number of children waste more food than the other group types. Fourth, consumers claimed to become more conscious about the quantum of FW as a direct response to the socio-economic circumstances imposed by the lockdown such as food availability, salary reduction, economic uncertainty and employment instability. Fifth, the attitude to keeping food on the plate does not change considerably.

This paper offers many practical implications. Using newly discovered pieces of evidence from practitioners, hoteliers and policymakers, this paper highlights current hospitality practices that can reduce the waste of food in a postpandemic world. Furthermore, our paper suggests a set of actions for restaurants offering open-buffet services to reduce FW at the consumption stage.

This paper adds significance to the extant tourist city literature. The tourist city served as an example of a recent urban development characterized mainly by tourist consumption. This research advances the understanding of FW management and customers’ behavior during the Covid-19 pandemic in an important touristic city “Dubai” and suggests a set of actions.

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

In this study, we attempt to investigate and examine the correlations among enterprise culture (EC), business ethic rules (BERs) and talented human resource supply chain management (THRSCM) in service SMEs in the Middle East region.

This study is quantitative in nature and adopts the quantitative-deductive hypothesis testing approach. To do this, a self-administrated survey was used and carried out to reach managers, human resource (HR) staff and workers from various small and medium-sized enterprises (SMEs) in the service sector that are listed in the Chambers of the Industries of Qatar, Saudi Arabia, the United Arab Emirates and Jordan in the Middle Eastern countries.

The empirical findings show that THRSCM and the BERs have a strong, positive correlation. Further, it found that there is also a strong and positive correlation between the EC and the BERs. As a result, THRSCM and EC can be extremely important in advancing and implementing BERs in SME service businesses. HR staff members should receive greater attention when implementing the BERs to accomplish the company’s goals and give customers a positive image of their enterprises. The HRM division and the company must be deeply aware of the significance of the BERs in their enterprises.

These findings can give managers, executives and HR staff helpful information to support the creation and upkeep of efficient business ethics rules inside their service SMEs.

Because there is not much study on the relationships between THRSCM, EC and BERs in the Middle East, this article attempts to investigate these relationships and consider them a benchmark for other future studies in ethics. Furthermore, it significantly influences service SMEs in the Middle East region.

This study aims to examine how knowledge sharing contributes to organizations’ ambidexterity, their overall performance and the role of knowledge quality in this relationship. Knowledge sharing is conceptualized based on tacit and explicit dimensions, and ambidexterity is viewed as comprising exploitative and explorative capabilities.

This study uses a cross-sectional survey-based research design and structural equation modeling to test the proposed model of knowledge sharing and knowledge quality in organizational ambidexterity and the related hypotheses.

The results indicate that tacit knowledge sharing has a significant, direct impact on the exploitative and explorative capabilities of the organization and indirectly impacts both dimensions of ambidexterity (i.e. exploitative and explorative) through knowledge quality. In contrast, explicit knowledge sharing does not have a significant impact on knowledge quality and affects only the exploitative extent of ambidexterity. Both exploitative and explorative capabilities significantly impact organizational performance.

To the best of the authors’ knowledge, this study is the first study to empirically examine the role of knowledge quality in the context of knowledge sharing for ambidexterity, especially within the context of organizations in the United Arab Emirates.

This study aims to enhance our understanding of sustainable water management in construction through a life-cycle embodied water assessment of a villa in the United Arab Emirates (UAE). It provides insights and recommendations for improving the water efficiency by identifying areas for potential embodied water saving and reduction in environmental impacts in the construction industry.

This study uses a life-cycle assessment (LCA) approach and focuses on a UAE villa as a case study. It analyses the embodied water consumption during construction (initial embodied water) and maintenance (recurrent embodied water) using an input–output-based hybrid analysis. Additionally, it compares the embodied water observations with the operational water usage and comprehensively evaluates the water consumption in the villa’s life-cycle.

The initial (28%) and recurrent embodied water (42%) represent significant proportions of a building’s life-cycle water demand. The structural elements, predominantly concrete and steel, contribute 40% of the initial embodied water consumption. This emphasises the importance of minimising the water usage in these materials. Similarly, internal finishes account for 47% of the recurrent embodied water. This emphasises the importance of evaluating the material service life.

These findings indicate the efficacy of using durable materials with low embodiment and water-efficient construction methods. Additionally, collaborative research between academia, industry, and the government is recommended in conjunction with advocating for policies promoting low embodied-water materials and transparency in the construction sector through embodied water footprint reporting.

Previous studies focused on the operational water and marginally addressed the initial embodied water. Meanwhile, this study highlights the significance of the initial and recurrent embodied water in the life-cycle water demand. It emphasises on the need for adaptable buildings with reduced embodied water and more durable materials to minimise the requirement for frequent material replacements.
