This research paper aims to investigate reinforced concrete (RC) walls' behaviour under fire and identify the thermal and mechanical factors that affect their performance.

A three-dimensional (3D) finite element (FE) model is developed to predict the response of RC walls under fire and is validated through experimental tests on RC wall specimens subjected to fire conditions. The numerical model incorporates temperature-dependent properties of the constituent materials. Moreover, the validated model was used in a parametric study to inspect the effect of the fire scenario, reinforcement concrete cover, reinforcement ratio and configuration, and wall thickness on the thermal and structural behaviour of the walls subjected to fire.

The developed 3D FE model successfully predicted the response of experimentally tested RC walls under fire conditions. Results showed that the fire resistance of the walls was highly compromised under hydrocarbon fire. In addition, the minimum wall thickness specified by EC2 may not be sufficient to achieve the desired fire resistance under considered fire scenarios.

There is limited research on the performance of RC walls exposed to fire scenarios. The study contributed to the current state-of-the-art research on the behaviour of RC walls of different concrete types exposed to fire loading, and it also identified the factors affecting the fire resistance of RC walls. This guides the consideration and optimisation of design parameters to improve RC walls performance in the event of a fire.

This paper investigates the potential mediating role of job satisfaction between role stressors, namely role conflict and role ambiguity as sources of stress, on the one hand, and various facets of organizational commitment, namely affective, continuance and normative, on the other. A sample of 361 employees in a number of organizations in the United Arab Emirates was used. Path analysis revealed that role ambiguity directly and negatively influences both affective and normative commitments. Results also revealed that job satisfaction directly and positively influences affective and normative commitments and negatively influences continuance commitment‐low perceived alternatives. Results further suggest that both role conflict and role ambiguity directly and negatively influence job satisfaction. It was also found that job satisfaction mediates the influences of role conflict and role ambiguity on various facets of organizational commitment, except continuance commitment‐high personal sacrifice. Implications, future lines of research and limitations are discussed.

The COVID-19 pandemic has affected around 216 countries and territories worldwide and more than 2000 cities in India, alone. The smart cities mission (SCM) in India started in 2015 and 100 smart cities were selected to be initiated with a total project cost of INR 2031.72 billion. Smart city strategies play an important role in implementing the measures adopted by the government such as the issuance of social distancing regulations and other COVID-19 mitigation strategies. However, there is no research reported on the role of smart cities strategies in managing the COVID-19 outbreak in developing countries.

This paper aims to address the research gap in smart cities, technology and healthcare management through a review of the literature and primary data collected using semi-structured interviews.

Each city is unique and has different challenges, the study revealed six key findings on how smart cities in India managed the COVID-19 outbreak. They used: Integrated Command and Control Centres, Artificial Intelligence and Innovative Application-based Solutions, Smart Waste Management Solutions, Smart Healthcare Management, Smart Data Management and Smart Surveillance.

This paper contributes to informing policymakers of key lessons learnt from the management of COVID-19 in developing countries like India from a smart cities’ perspective. This paper draws on the six Cs for the implications directed to leaders and decision-makers to rethink and act on COVID-19. The six Cs are: Crisis management leadership, Credible communication, Collaboration, Creative governance, Capturing knowledge and Capacity building.

The purpose of this paper is to review previous research studies on mathematical models for entropy generation in the magnetohydrodynamics (MHD) flow of nanofluids. In addition, the influence of various parameters on the velocity profiles, temperature profiles and entropy generation was studied. Furthermore, the numerical methods used to solve the model equations were summarized. The underlying purpose was to understand the research gap and develop a research agenda.

This paper reviews 141 journal articles published between 2010 and 2022 on topics related to mathematical models used to assess the impacts of various parameters on the entropy generation, heat transfer and velocity of the MHD flow of nanofluids.

This review clarifies the application of entropy generation mathematical models, identifies areas for future research and provides necessary information for future research in the development of efficient thermodynamic systems. It is hoped that this review paper can provide a basis for further research on the irreversibility of nanofluids flowing through different channels in the development of efficient thermodynamic systems.

Entropy generation analysis and minimization constitute effective approaches for improving the performance of thermodynamic systems. A comprehensive review of the effects of various parameters on entropy generation was performed in this study.

This study aims to examine the impact of board gender diversity on the level of corporate social responsibility (CSR) disclosure in the Arab Gulf states. Also, this research further aims to explore whether the impact of board gender diversity varies across the Arab Gulf states.

Ordinary least squares regression is used in this study to test the impact of board gender diversity on the level of CSR disclosure. Manual content analysis is used to evaluate the extent of CSR disclosure in annual reports, stand-alone CSR reports, sustainability reports and website sections to examine the relationship between the extent of CSR reporting and board gender diversity. This study uses the global reporting initiative (GRI) fourth version reporting guidelines to design and define the classifications of CSR reporting checklist.

The findings show that there is a statistically significant relationship between the number of female directors and the level of CSR disclosure. The results show that board gender diversity is positively associated with the level of CSR reporting in two countries, namely, Bahrain and Kuwait. Also, the findings reveal that there is a weak positive relationship between the presence of women on the boards and CSR reporting index in Oman, Qatar, Saudi Arabia and the UAE.

This study attempts to fill the gap in the literature, in that no similar study covers the Arab Gulf countries as one economic unit. The study is unique in that it focuses on oil-rich countries. This study is, to the best of this researcher’s knowledge, the first to explore the impact of women’s boards on the extent of CSR reporting, as well as investigating the possible variation of board gender diversity impact on the extent of CSR reporting in the Arabian Gulf region.

This study aims to investigate the relationship between person-role conflict, psychological capital and emotional exhaustion. Specifically, the research explores how person-role conflict magnified due to daily contact with COVID-19 carriers leads doctors and nurses to experience emotional exhaustion. Moreover, psychological capital function as an explanatory mechanism between stressor strain relationships has also been tested.

The study results are based on three months of lagged data conducted from the sample of 347 frontline physicians and nurses who provide treatment and care to infected people. To test direct, indirect and total effect, the author's used PROCESS Macro.

The results suggested that person-role conflict reduces state-like psychological capital and increases emotional exhaustion through reduced psychological capital. Results aligned with the model's expectations in that psychological capital mediated the relationship between person-role conflict and emotional exhaustion, and the mediation was partial.

This paper is the first one that tested the link between person-role conflict and emotional exhaustion. Moreover, up till now, no study has examined the mediating role of psychological capital in the relationship between person-role conflict and emotional exhaustion. Finally, in the context of the contagion outbreak, this is the preliminary effort that validated the resource loss cycle principle of conservation of resource theory.

In light of the widely acknowledged significance of GHRM practices, this study improves comprehension pertaining to GHRM practices and employee workplace outcome relationships. Drawing on the conservation of resource (COR) theory, the association between GHRM practices and employee workplace outcomes, namely green commitment and thriving at work, was explored, with a specific focus on the mediating role of organizational pride.

A quantitative research design was adopted, and data was collected through a multistage sampling technique, yielding a sample of 255 employees working in six textile manufacturing organizations in Pakistan, all of which held the ISO 14001 certification. The model was tested using Partial Least Square Structural Equation Modeling (PLS-SEM).

The findings of this study reveal a significant link between GHRM practices and organizational pride. Moreover, organizational pride was found to mediate the relationship between GHRM practices and thriving at work while partially mediating the relationship between GHRM practices and green commitment.

The outcomes of this study have implications for organizations seeking to enhance sustainability and employee well-being by adopting GHRM practices. Specifically, fostering a sense of organizational pride can further enhance thriving at work and green commitment among employees.

The findings contribute to the existing literature by highlighting the positive impact of GHRM practices on employee workplace outcomes and the importance of organizational pride as a mediating mechanism.

The purpose of this study was to examine a factor structure of human resource management (HRM) practice scales through testing a causal model of HRM practices and to have one combined composite multi-dimensional HRM scale, to identify possible future directions for HRM strategy development and professional practice in Jordan.

Data were collected from 493 front-line employees from Jordanian organisations. The measurement model was tested on the complete dataset using exploratory factor analysis employing SPSS 17.0. Maximum likelihood method was used to determine the underlying factor structures. Confirmatory factor analysis was employed using LISREL 8.80 to further investigate the latent structure of the factors.

This study finally evidenced a good fit of data for a hypothesis four-factor model. The final model supported a conceptual framework that is inclusive of four domains, recruitment and selection, training and development, performance appraisal, and rewards and benefits, and lends support to the construct validity of the consolidated HRM practices scale.

First, the limited amount of research available on HR practices has limited the opportunity to gather content-rich information from the previous studies. Second, this study used three different scales to measure the four HRM practices as there was no one composite scale. Third, the validation of the HRM practices scale was based entirely on front-line employees working in Jordanian organisations. As a result, the psychometric properties of the HRM practices scale may not be generalisable to varied professions.

The findings of the study highlight the importance of the composite views of the HRM practices scale as a multi-dimensional construct. The study illustrates the parameter estimates representing relationships between the constructs under investigation.

The present study emphasises the need to expand the focus on HRM practices and contributes to the knowledge in several grounds. First, it validates the structure of HRM practices scales in Jordan. Second, this study enriched the understanding of HRM practices, drawing a sample of participants from different sectors (insurance, finance, services, accounting and industry), and suggests that these variables are as equally prominent as others in explaining employees' attitudes toward HRM practices.

The current study examined employment rates and predictors of employment among Syrian refugees currently living in Lebanon and Jordan. This paper argues that men and women refugees have different experiences seeking out employment after resettlement due to patriarchal structures and attitudes toward women that are present in the Arab Middle East. The goals of this paper were a) to examine employment rates among Syrian refugees, b) to examine predictors of employment among male and female refugees, and c) to examine refugee status as a moderator of the relationship between attitudes toward women and employment status.

Nationally representative data from the Arab Barometer on 600 refugees and 1400 native-born individuals living in Lebanon and Jordan from 2016–2017 were used.

Native-born individuals living in Lebanon and Jordan were 2.16 times more likely to be employed than refugees. Men living in Lebanon and Jordan were 7.83 times more likely to be employed than women. Finally, refugee status moderated the relationship between attitudes toward women's rights and roles and employment. Among native-born women, a positive attitude toward women's rights and roles predicted employment status, whereas this positive relationship was not found for women refugees. Among refugee men, a positive attitude toward women's rights and roles was linked to a lower likelihood of holding a job.

These findings suggest that agencies supporting refugees should communicate realistic expectations about employment during resettlement and should address the challenges that women refugees face when seeking employment.

This study is the first study to identify attitudes toward women's rights and roles as a predictor of employment among refugee populations and highlights the unique struggles that refugee women face.

This paper aims to analyze the Egyptian revolution as an anti-systemic movement. It illustrates how Egypt’s position in the world-economy has affected its political economy orientation and led to the marginalization of critical masses, who launched the revolution.

The paper follows Wallerstein’s world-system analysis focusing on the anti-systemic movement concept. The paper analyzes the Egyptian case based on Annales school’s longue durée concept, which is a perspective to study developments of social relations historically.

The Egyptian revolution was not only against the autocratic regime but also against the power structure resulting from the neoliberal economic policies, introduced as a response to the capitalism crisis. It represented the voice of the forgotten. The revolution was one of the anti-systemic movements resisting the manifestations of the capitalist world-economy.

This paper aims at proving that the Egyptian revolution was an anti-systemic movement; which will continue to spread as a rejection to the world-system and to aspire a more democratic and egalitarian world. The current COVID-19 pandemic is exacerbating the crisis of the world-system.
