The choice between different financing sources is governed by a number of finance theories, particularly, trade-off theory and pecking order theory. However, the special characteristics of Islamic finance, which forces the exclusion of conventional bonds, leave Islamic banks with limited number of alternatives. Tier 1 sukuk are distinguished type of sukuk that combines the features of conventional bonds and stocks. This paper aims to answer the following question: Does the issuance of Tier 1 sukuk positively affect Islamic banks’ profitability or is their impact concentrated on enhancing Islamic banks’ capital adequacy ratios?

The data set used in this study consists of all United Arab Emirates (UAE) Islamic banks that issued Tier 1 sukuk over the period 2010–2020. Pooled and fixed effects panel regressions of Tier 1 sukuk and other control variables on three proxies of Islamic banks’ profitability were run. The selection of fixed-effect model is based on Hausman test, redundant fixed effects and likelihood ratio test.

This study reveals novel findings. Tier 1 sukuk increases both earnings per share (EPS) and capital adequacy ratios. That is, this study finds that there is a positive significant impact of Tier 1 sukuk on EPS, which indicates that issuing more Tier 1 sukuk will generate more return to shareholders in terms of higher EPS because of the lower cost of Tier 1 sukuk compared to equity. However, this study finds that there is an insignificant impact of Tier on sukuk on both return on assets and return on equity. Hence, it is concluded that Tier 1 sukuk does not increase the risk appetite of UAE Islamic banks.

Tier 1 sukuk is a niche instrument that has been recently used by Islamic banks. Hence, there are a limited number of Islamic banks that have issued this type of sukuk and consequently limited number of observations. Therefore, with the increased use of this instrument, a larger set of data will be available for examination. In addition, future research could examine the relationship between issuing Tier 1 sukuk and profitability in other countries where such sukuk have loss absorption feature. The impact of other types of sukuk, such as liability sukuk, on Islamic banks’ profitability could also be an interesting field of study.

This study recommends Islamic banks to issue more Tier 1 sukuk to enhance their profitability indicators while meeting Basel III accord. This study also recommends investors to purchase the stocks of Islamic banks that issue Tier 1 sukuk because they are able to offer them higher EPS. The authors advise the UAE regulators to allow Islamic banks to issue Tier 1 sukuk with loss absorption feature to enable Islamic banks engage in more risky activities that usually provide larger profits. This study also suggests that the Islamic Financial Services Board (IFSB) reclassifies Tier 1 sukuk, with loss absorption feature, within the highest quality of capital, common equity Tier 1, to encourage Islamic banks to issue this type of sukuk, especially Basel III accord and IFSB 15 require higher ratios of common equity Tier 1 to risk-weighted assets.

This research contributes to the existing literature in two ways. First, it adds to the existing literature on the impact of sukuk on Islamic banks profitability. That is, contrary to prior studies that merely investigate the impact of issuing ordinary sukuk on profitability, this study explores a distinguished type of sukuk, that is Tier 1 sukuk, that has been surprisingly ignored so far. Second, this study shows that it is not only capital adequacy ratios that have improved as a result of issuing Tier 1 sukuk but also Tier 1 sukuk reduce the cost of capital of UAE Islamic banks which has been reflected in a higher profitability proxied by EPS. Hence, these sukuk serve a dual function for Islamic banks by improving both capital adequacy and profitability ratios.

From managerial perspective, the authors investigate the boundary and effective conditions of recruitment practices (e.g. job advertising and manager recruiting behavior) on recruitment outcomes that include employer image and organizational commitment in the context of recruitment practices. Drawing on signaling theory, the authors argue that using recruitment practices is generally more effective for creating employer image and organizational commitment.

The authors received a final sample of 213 from the employees of beverage industry. In doing so, statistical softwares SPSS (v.23) for data screening and SmartPLS (v.3.3.3) were used for hypothesis testing.

Using survey-based study, the study finds (1) that recruitment practices including job advertising and managers' recruiting behavior can be superior to developing employer image that positively can value the organizational commitment (2) The study identifies a significant role of employer image that is mediating between recruitment practices and post recruitment outcome (e.g. organization commitment).

The outcomes of the study provide valuable directions for human resource (HR) managers in national and multinational public organizations. The article offers recruitment strategies/practices to enhance employer image and organizational commitment.

The novelty of the study is the unique research framework, as the current paper is among the pioneers to empirically analyze the effect of recruitment practices on post-recruitment outcome testing the mediating relationship of employer image between job advertising organizational commitment and between managing recruiting behavior and organizational commitment.

The survival of hotel business in maintaining market competitiveness depends on the constant improvement of the quality of hotel facilities and services. The key to sustain hotel business is lean on the adaptability of the hotel management team towards current lifestyle trends and its surrounding context in fulfilling customer satisfaction. Because of hotel operating service complexity, the hotel contributes a higher impact on environmental degradation in performing their daily activities. Therefore, hoteliers need to determine sustainable strategies to minimize environmental impact and at the same time be able to provide satisfaction to their customers. However, green initiatives require a proactive action by the organizational management engaging both employees and guests in the environmental management process. Thus, this paper aims to review the concept of green practices, the implementation of green practices from the stakeholders’ perspectives (manager, employee and customers) in the hotel industry, the performance impact from the green practices on the sustainability pillars and to further develop a conceptual green practice to sustainable hotel operations and performance impact.

This paper identified relevant empirical research that published in the recent 10 years from January 2012 to December 2021. The articles are searched through reputable databases such as Emerald, Elsevier and Taylor and Francis. The obtained data were screened preliminarily from 108 research papers. The post-screening process has finalized a total of 57 articles as the findings for this paper, where the themes were delineated to the attributes that need to implemented by the stakeholder in hotels industry, that is, manager’s perspectives, employee’s perspectives and customer’s perspectives.

The findings of this paper revealed that there are 27 attributes of green practices and initiatives for sustainable hotel operations from the manager perspectives (10 attributes – Green Marketing Strategy, Green Managerial Attitude, Eco-Innovation Investment, Marketing and Sustainability, Environmental Management Strategy, Green Supply Chain, Green Managerial Awareness, Green Procurement, Green Human Resources and Green Technology), employee perspectives (5 attributes – Employee Green Awareness, Employee Green Training and Educating, Employee Environmental Behaviour, Employee Green Performance and Employee Green Reward) and customer’s perspectives (12 attributes – Customer Perception, Customer Loyalty, Customer Awareness, Customer Behaviour, Customer Trust, Green Supply Chain, Green Value, Green Marketing Strategy, Customer Perceived Value, Service Quality, Brand Image and Hotel Design). All of the attributes are aligned to the performance effectiveness as the major concern in the hotel’s operations and impacted towards the sustainability pillars, environmental performance, economic performance and social performance. Sustainable practice in organization benefits the owners towards sustainable economic, environmental, socio-cultural and legal policy.

This review paper provides key elements of current green practices and sustainable initiatives for the hotel’s operations, as proactive measures. The novelty of the findings is to be able to convey valuable inputs to the relevant stakeholders (hotel’s owner, consultants, designers, maintenance officers, hoteliers, staffs, customers and end-users) in perceiving the elements of green practices into the preliminary planning of the hotel’s design. The review also helps to identify practices and measures to the performance impact to the hotel’s operations.

Augmented reality (AR) is an emergent technology that has been impacting and beneficial to various industries. This is especially the case in the tourism industry since the COVID-19 crisis. To enable and enhance the museum experience, AR technology can be used as a tool to manage visitors' experiences and adapt to the digital transformation of industries. This research work aims to explore the acceptance of museum visitors for the adoption of this technology. For this purpose, the technology acceptance model (TAM) is used as the research lens.

The authors collected 316 responses from a survey handed out to prior visitors of immersive exhibitions shown via AR at the Atelier des Lumières in Paris and analyzed them through a structural equation model approach.

The study’s findings explain the behavior of visitors when attending immersive exhibitions according to the TAM and highlight two new constructs that need to be considered when using the TAM with AR technology: user satisfaction and social mimetism.

The study’s findings support that implementing AR technology in the museum industry provides great opportunities for the tourism industry to recover from the economic crisis that followed from the COVID-19 health crisis. The authors identified new thriving concepts in the 21st century with the rise of social media, such as social mimetism, that propels visitors to have a positive attitude and intention to attend immersive exhibitions.

Upon the premises of social exchange theory (SET), this study aimed at hypothesizing and examining a serial mediation model that investigated the underlying mechanism through which a high-performance work system (HPWS) affects individuals’ future time perspective (FTP).

The hypothesized relationships were examined using responses collected from 275 employees from 15 local private banks and 40 established branches through a proportionate stratified sampling technique. The statistical package for social sciences (SPSS) PROCESS macro 3.0 and analysis of moment’s structure (AMOS) 24.0 were employed for data analysis purposes.

The study revealed that HPWS is indirectly related to the individuals’ FTP through workplace social courage (WSC) and employee well-being (EWB) sequentially. Prescriptions for theoretical and managerial implications were discussed, and future research viewpoints with limitations were acknowledged.

This study illuminated the underlying mechanism and theoretical logic linking HPWS and individuals’ FTP by proposing the serial mediating effect of WSC and EWB.

This study aims to investigate the morphing concepts able to manipulate the dynamics of the downstream unsteadiness in the separated shear layers and, in the wake, be able to modify the upstream shock–boundary layer interaction (SBLI) around an A320 morphing prototype to control these instabilities, with emphasis to the attenuation or even suppression of the transonic buffet. The modification of the aerodynamic performances according to a large parametric study carried out at Reynolds number of 4.5 × 10⁶, Mach number of 0.78 and various angles of attack in the range of (0, 2.4)° according to two morphing concepts (travelling waves and trailing edge vibration) are discussed, and the final benefits in aerodynamic performance increase are evaluated.

This article examines through high fidelity (Hi-Fi) numerical simulation the effects of the trailing edge (TE) actuation and of travelling waves along a specific area of the suction side starting from practically the most downstream position of the shock wave motion according to the buffet and extending up to nearly the TE. The present paper studies through spectral analysis the coherent structures development in the near wake and the comparison of the aerodynamic forces to the non-actuated case. Thus, the physical mechanisms of the morphing leading to the increase of the lift-to-drag ratio and the drag and noise sources reduction are identified.

This study investigates the influence of shear-layer and near-wake vortices on the SBLI around an A320 aerofoil and attenuation of the related instabilities thanks to novel morphing: travelling waves generated along the suction side and trailing-edge vibration. A drag reduction of 14% and a lift-to-drag increase in the order of 8% are obtained. The morphing has shown a lift increase in the range of (1.8, 2.5)% for angle of attack of 1.8° and 2.4°, where a significant lift increase of 7.7% is obtained for the angle of incidence of 0° with a drag reduction of 3.66% yielding an aerodynamic efficiency of 11.8%.

This paper presents results of morphing A320 aerofoil, with a chord of 70cm and subjected to two actuation kinds, original in the state of the art at M = 0.78 and Re = 4.5 million. These Hi-Fi simulations are rather rare; a majority of existing ones concern smaller dimensions. This study showed for the first time a modified buffet mode, displaying periodic high-lift “plateaus” interspersed by shorter lift-decrease intervals. Through trailing-edge vibration, this pattern is modified towards a sinusoidal-like buffet, with a considerable amplitude decrease. Lock-in of buffet frequency to the actuation is obtained, leading to this amplitude reduction and a drastic aerodynamic performance increase.

The purpose of this study is to provide a timely synthesis of the empirical literature focusing on the economic consequences of money laundering, as this topic has been gaining momentum among policymakers and academic researchers due to its adverse effects.

Empirical studies are collected by consulting accounting and finance journals in diverse digital sources (e.g. Science Direct, Blackwell, Taylor and Francis, Springer, Sage and Emerald). Key words used to identify relevant papers include “money laundering” and “anti-money laundering regulations,” with specific focus on the economic consequences. Our search strategy includes 24 published papers over the period of 2018–2023.

Findings show that most studies represent cross-country investigations; the main topics investigated focus on accounting field (e.g. audit fees, real and accrual earnings management), tax evasion, financial stability, sustainability, economic indicators (inflation, economic growth, foreign direct investment) and financial inclusion; and the economic consequences of money laundering have been also examined within banking industry (e.g. banking profitability, banking stability). Reported findings of reviewed studies suggest that money laundering has diverse adverse impacts at the country level (e.g. increased tax evasion, higher inflation rate, less sustainability and foreign direct investments), at the firm level (e.g. increased audit risk and aggressive real and accrual earnings management) and within banking industry through negative impact of money laundering on bank’s loan portfolio quality, stability and profitability.

With respect to policymakers, strengthening anti-money laundering regulations may play a critical role in reducing money laundering activities. Furthermore, financial institutions should implement specific rules dealing with anti-money regulations to ensure adequate compliance and disclosure. Finally, policymakers should be aware about the importance of digital transformation to combat money laundering activities since it facilitates the detection of financial crimes due to their traceability.

The summary of the empirical literature focusing on the economic consequence of money laundering represents a historical record and an introduction for accounting researchers. It also urges them to further explore the economic implications of anti-money laundering disclosure within banking industry.

Knowledge sharing has become necessary for organizations as it is a source of competitive advantage. Therefore, this study aims to investigate how empowering leadership through psychological empowerment encourages employees’ knowledge-sharing (KS) behavior. This study further explores the moderating role of learning goal orientation (LGO) between psychological empowerment and KS behavior.

This study collected data from 423 employees working in manufacturing and service organizations in two waves on convenience basis to tackle common method variance. The data were analyzed through structural equation modeling.

The results revealed that empowering leadership helps employees modify their KS behavior both directly and indirectly in the presence of psychological empowerment. Moreover, individuals high in LGO are more likely to involve in KS behavior when psychologically empowered.

This study used a cross-sectional design and suggests management focus on their working environment to enhance knowledge sharing among employees, which is possible through empowering leaders. The study further suggests management not ignore individual attributes during recruitment.

Drawing upon job characteristics model and social exchange theory, this study explores the mediating role of psychological empowerment between empowering leadership and KS behavior and the moderating role of LGO on the association between psychological empowerment and KS behavior.

This study aims to investigate the efficacy of Ag@GO/Na₂SiO₃ nanocomposite in eliminating As from aqueous solutions. Employing response surface methodology, the research systematically examines the adsorption process.

Various experimental parameters including sample pH, contact time, As concentration and adsorbent dosage are optimized to enhance the As removal process.

Under optimized conditions, the initial As concentration, contact time, pH and adsorbent dosage are determined to be 32 ppm, 50 mins, 6.5 and 0.4 grams, respectively. While the projected removal of As stands at 97.6% under these conditions, practical application achieves a 93% removal rate. Pareto analysis identifies the order of significance among factors as follows: adsorbent dosage > contact time > pH > As concentration.

This study highlights the potential Ag@GO/Na₂SiO₃ as a promising adsorbent for efficiently removing industrial As from aqueous solutions, and it is likely to have a good sufficiency in the filtration of water and wastewater treatment plans to remove some chemical pollution, including paints and heavy metals.

The simplicity of the nanocomposite preparation method without the need for advanced equipment and the cheapness of the raw materials and its potential ability to remove As are the prominent advantages of this research.
