The purpose of the study is to numerically investigate the characteristics of laminar heat transfer and fluid flow in a double tube heat exchanger (DTHE) using water-aluminum oxide (Al₂O₃) nanofluid. The study examines the effects of nanofluid in both counter and parallel flow configurations. Furthermore, an exergy analysis is conducted to assess the impact of nanofluid on exergy destruction.

The single-phase method has been used for Al₂O₃ nanoparticles in water as base fluid in a laminar regime for Reynolds numbers from 400 to 2,000. The effects of nanoparticle volume fractions (0 to 0.1), Nusselt number, Reynolds number, heat transfer coefficient, pressure drop, performance evaluation criteria (PEC) and the impact of counter and parallel flow direction have been studied.

The findings indicate that the incorporation of nanoparticles into the water enhances the heat transfer rate of DTHE. This enhancement is attributed to the improved thermal properties of the working fluid and its impact on the thermal boundary layer. Nusselt number, heat transfer coefficient, and PEC increase by approximately 19.5%, 58% and 1.2, respectively, in comparison to pure water. Conversely, the pressure drop experiences a 5.3 times increase relative to pure water. Exergy analysis reveals that nanofluids exhibit lower exergy destruction compared to pure water. The single-phase method showed better agreement with the experimental results compared to the two-phase method.

Dimensionless correlations were derived and validated with experimental and numerical results for the Nusselt number and PEC for both counter and parallel flow configurations based on the Reynolds number and nanoparticles volume fraction with high accuracy to predict the performance of DTHE without performing time-consuming simulations. Also, an exergy analysis was performed to compare the exergy destruction between nanofluid and pure water.

The aim of this study is to conduct a comparative analysis between Islamic and conventional banks in terms of whether Islamic banks was more or less resilient/risky than conventional counterparts to the pandemic shock. It also examines the role of capital in improving the performance and stability within the two banking systems.

This study uses 82 banks from MENA (Middle East and North Africa) region for periods across 2011–2020, and employs a dynamic panel data approach to examine the resilience within both banking systems during the Covid-19 pandemic.

The results show that the Covid-19 pandemic has a negative impact on conventional banks' stability. However, Islamic banks performed better and were less risky than conventional ones. Banks with high-quality capital are more effective at controlling their risks and improving their performance during the pandemic.

The results offer important financial observations and policy implications to many stakeholders engaging with banks. Actually, the findings of this study facilitate to the stakeholders and bankers to have an alluded picture about determinants of risk and performance. The results can be used by bankers’ policy decision-makers to improve and enhance their consideration for risk management, taking into consideration the type of banking systems.

Compared to the various studies on the stability of Islamic and conventional banks, researchers have not sufficiently addressed the effect of the Covid-19 pandemic on risk and performance. Moreover, none of these studies has examined if Islamic banks was more or less resilient/risky than conventional counterparts to the pandemic shock. This leads the authors to identify the similarities and differences between two types of banks in the MENA region in a pandemic shock context.

This paper aims to examine the effect of the auditors’ burnout determinates on audit quality and performance. It also analyses whether the demographic characteristics of gender, age group, education and job positions affect auditors’ decisions for burnout, audit quality and performance.

A questionnaire was distributed on a sample of auditors in the top ten auditing firms in an emerging market including the Big 4. Factor analysis, correlation matrix and structural equation modeling were used for the analysis of the collected data and testing the developed hypotheses.

The results show that burnout has negative consequences for both the auditor and the auditing firm. While good organizational climate has a negative significant association with audit quality, nonethical decisions and audit performance, role clarity has positive significant association with the audit quality and performance and has an insignificant association with nonethical decisions. Also, turnover intention has significant positive association with nonethical decision, audit quality and performance.

This research is among the first to focus on auditor’s burnout determinates on audit quality and performance in an emerging market characterized by different socioeconomic, political and cultural factors compared with those of developed markets. Auditors, regulators and professional policymakers can benefit from the results of this research.

The first purpose of this paper is to investigate whether corporate governance mechanisms, in particular the characteristics of the board, audit committee and risk management committee, are associated with the level of disclosure in integrated reports of South African listed firms. The second purpose of this paper is to analyze how integrated reporting (IR) affects the sustainable development goals (SDGs).

This paper uses a mixed methods approach. First, a multiple regression analysis is used to estimate the impact of corporate governance mechanisms on IR practices of a sample of South African listed firms during the period between 2019 and 2021. Using the content analysis method to measure the level of IR, disclosures were measured using a disclosure index consisting of 60 information items developed from the IIRC framework and previous studies. Second, based on a database containing 33 articles in the Meditari Accountancy Research journal with a publication date from 2013 to 2021, a systematic review of the academic literature focusing on IR is conducted to analyze how IR influences SDGs.

The results indicate that board size, board independence and risk management committee independence have a positive effect on IR practices. However, board expertise, board activity, audit committee independence, audit committee size, audit committee expertise, audit committee meetings, risk management committee expertise, risk management committee meetings, risk management committee size and the auditor type are negatively related to IR practices. The results also indicate that IR has an important role in achieving SDGs by relying on integrated thinking that integrates sustainability into the enterprise’s strategy and helps the integration of capitals. In addition, sustainable business models create long-term values.

This study was limited to a sample size of 75 firms, which is country-specific; however, it sets the tone for future empirical research on the subject matter. This study provides an avenue for future research in the area of corporate governance and IR practices in other emerging countries, especially other African countries.

This study provides useful insights for managers and policymakers to better understand which corporate governance mechanisms can best encourage a company to improve IR practices.

To the best of the author’s knowledge, this study is, perhaps, the first to examine the effect of risk management committee characteristics on IR practices. This study provides new insight into the contribution of accounting research toward the achievement of SDGs.

This study’s aim is to introduce a high-performance sorbent for the removal of both anionic (Congo red; CR) and cationic (methylene blue; MB) dyes from aqueous solutions.

Sodium silicate is adopted as a substrate for GO and AgNPs with positive charge are used as modifiers. The synthesized nanocomposite is characterized by FTIR, FESEM, EDS, BET and XRD techniques. Then, some of the most effective parameters on the removal of CR and MB dyes such as solution pH, sorbent dose, adsorption equilibrium time, primary dye concentration and salt effect are optimized using the spectrophotometry technique.

The authors successfully achieved notable maximum adsorption capacities (Qmax) of CR and MB, which were 41.15 and 37.04 mg g⁻¹, respectively. The required equilibrium times for maximum efficiency of the developed sorbent were 10 and 15 min for CR and MB dyes, respectively. Adsorption equilibrium data present a good correlation with Langmuir isotherm, with a correlation coefficient of R2 = 0.9924 for CR and R2 = 0.9904 for MB, and kinetic studies prove that the dye adsorption process follows pseudo second-order models (CR R2 = 0.9986 and MB R2 = 0.9967).

The results showed that the proposed mechanism for the function of the developed sorbent in dye adsorption was based on physical and multilayer adsorption for both dyes onto the active sites of non-homogeneous sorbent.

The as-prepared nano-adsorbent has a high ability to remove both cationic and anionic dyes; moreover, to the high efficiency of the adsorbent, it has been tried to make its synthesis steps as simple as possible using inexpensive and available materials.

The purpose of this study is to look at the structure of the interactions between the board of directors’ chairman qualities such as chairman independence, tenure, ethnicity, age- and impression management (IM).

The research population consists of non-financial Malaysian companies listed on Bursa Malaysia’s Main Market, using data gathered via annual reports and DataStream. The study relies on the ordinary least square regression to test the direct relationships between the directors’ chairman characteristics and IM. Moreover, robustness and sensitivity tests were used to examine the effectiveness of chairman characteristics with IM. Furthermore, the results rely on the FGLS regression as an additional test. The study found that chairman independence, chairman ethnicity and chairman age have a significant impact on IM.

The results reveal that chairman independence has a negative association with qualitative IM (IMSC1). Moreover, chairman ethnicity has a positively significant relationship with qualitative IM (IMSC1) and quantitative IM (IMSC2). Also, the effectiveness of chairman characteristics has a negative and significant association with IMSC1.

The primary goal of this paper is to fill a gap in the literature and to open up opportunities for more in-depth research on the subject. So far, there has been no research into the impact of the board chairman’s (BC) personality on IM. This study serves as a warning to policymakers, businesses and their stakeholders, as well as researchers, about the importance of BC characteristics, which may impede the effectiveness of corporate governance mechanisms. The paper provides a framework for investigating these characteristics in the context of IM.

This paper aims to investigate the efficiency and performance of the Islamic banking industry amid the COVID-19 pandemic.

The authors used a two-stage data envelopment analysis to first estimate the efficiency of 78 Islamic banks (IBs) across 15 countries for the 2005–2020 period (a total of 782 bank-year observations) and then to examine their determinants, including the COVID-19 pandemic.

The authors found that the Islamic banking industry performed at a moderate level during the 2005–2020 period, providing evidence that IBs are resilient to the financial shocks created by COVID-19. The authors also found that bank-level characteristics (such as bank size) and country-level characteristics (such as inflation) can contribute to the bank’s operational efficiency.

The results of this study suggested that banking management and government macroeconomic policy, especially in terms of precautions and continuous support, are important for IBs to improve their performance.

To the best of the authors’ knowledge, this is the first study to examine the efficiency and performance of IBs amid COVID-19.

Highly committed, motivated and engaged employees assure organizational success and competitiveness. The study aims to examine the association between human resource development (HRD) practices and employee engagement with organizational commitment as a mediating variable.

Data were collected from 760 employees of 13 star-rated hotels comprising 5 (five-star) and 8 (four-star). The data supported the hypothesized relationships. Structural equation modeling was used to evaluate the proposed model and hypotheses. Construct validity and reliability were established through confirmatory factor analysis.

The results indicate that HRD practices and affective commitment are significantly associated. HRD practices and continuance commitment were shown to be non-significantly associated. HRD practices and normative commitment were shown to be non-significantly associated. Employee engagement and organizational commitment are significantly associated. The results further show that organizational commitment mediates the association between HRD practices and employee engagement.

The generalizability of the findings will be constrained due to the research's hotel industry focus and cross sectional data.

The study's findings will serve as valuable pointers for stakeholders and policymakers of the hotel industry in the adoption, design and implementation of proactive HRD interventions to keep highly engaged and committed employees for organizational competitiveness and sustainability.

By evidencing empirically that organizational commitment mediates the nexus between HRD practices and employee engagement, the study extends the literature.

This paper aims to systematically review the field of non-financial reporting (NFR) in hybrid organizations, focusing on state-owned enterprises, third-sector organizations and public–private partnerships. This is a timely attempt to identify the state of the art in the literature and outline the future research agenda. The paper answers two research questions: RQ1. What can be learned about NFR in hybrid organizations from the existing literature? RQ2. What are the future avenues for research on the topic?

A systematic literature review method was applied in this paper to summarize evidence from extant literature on NFR in hybrid organizations. The Scopus and Web of Science Core Collection databases were used to locate 92 articles for the review.

Recent years have witnessed a sharp increase in the number of articles on the topic. Regarding the implications of NFR for hybrid characteristics, NFR has some potential to strengthen the influence of non-market (i.e. state, community and social) logics in hybrid organizations. However, this potential may be limited due to the effect of market logics and the tensions that arise between the multiple logics in hybrid organizations. Regarding the implications of hybrid characteristics for NFR, these characteristics can not only affect the extent, the quality, the likelihood and the institutionalization of NFR but also result in the development of new NFR frameworks. The review calls for more research on the implications of NFR for multiple institutional logics and the implications of these logics for NFR in hybrid organizations.

To the best of the authors’ knowledge, this is the first literature review that mobilizes insights from hybridity research to analyze NFR literature on diverse hybrid organizations.

This study aims to analyse how talent management practices in family-owned hotels contribute to their employees' fulfilment of their psychological contract.

Semi-structured interviews were conducted with 30 employees working at three different family business hotels in Sharm El-Sheikh, Egypt. Moreover, thematic analysis was undertaken on the collected data resulting in four major themes.

The findings revealed that stimulating employees to fulfil their psychological contract towards their family-owned hotels leads to several benefits. First, it leads to talent management practices that support crisis management, sustainability and resilience. Second, it contributes to empathy towards or at least a deep concern for the future of work in the hospitality sector. Third, to fulfil their psychological contract, employees, particularly non-family members, require inclusive talent management and ongoing training programmes tailored to prepare them to meet current and future challenges in the hospitality sector.

To the best of the authors' knowledge, the present study is the first study to empirically investigate the relationship between talent management practices and the psychological contract of employees in family-owned hotels, especially in developing economy context of Egypt. Also, it is one of the pioneering studies to unpack these dynamics for family as well as non-family employees.
