The purpose of this paper is to explore the impact of human resource (HR) management practices on achieving competitive advantage through studying the mediating role of employee satisfaction in the context of five-star hotels in Northern Cyprus.

To produce numeric data as well as to test the hypothesis, the researchers employed structural equation modeling and AMOS. The testing included (n=439) questionnaires. The model suggested by the authors examined the tourism sector, and in particular, five-star hotels located in Northern Cyprus.

The main research findings revealed that HR practices had a significant effect on competitive advantage. By comparison, the research findings revealed that the mediator variable had no effect on achieving competitive advantage for five-star hotels in Northern Cyprus.

This study demonstrates originality by responding to the recommendations of prior studies conducted on HR in Northern Cyprus Island. This makes a theoretical contribution to the field, since only Turkey recognizes Northern Cyprus, which makes conducting research on this country a challenge for researchers worldwide. Based on this study’s outcomes, this paper discusses its theoretical and practical implications, as well as recommendations for future research.

This study attempts to identify and analyze the pragmatic functions of religious expressions, that is, invocations that include the name of Allah (God), in naturally occurring social interactions in Najdi Arabic, which is spoken in Central Saudi Arabia.

Drawing on the speech act theory and politeness model, an analysis of the data illustrates that religious expressions, in addition to their prototypical religious meanings and uses in everyday interactions, are employed to communicate a wide range of pragmatic functions.

These include signaling the end of a conversation, persuading, mitigating and hedging, showing agreement and approval, reinforcing emphasis, expressing emotions, seeking protection from the evil eye, conveying skepticism and ambiguity, expressing humor and sarcasm, and showing respect and honor. The embedded multifunctional dimension of religious expressions in the present data is interpreted as serving as a politeness marker with which speakers promote both positive politeness (by showing solidarity, claiming common grounds, and building rapport) and negative politeness (by reducing imposition and emphasizing personal autonomy).

This study further highlights the interplay between religion, culture, and language use in Najdi Arabic.

Prevention through Design (PtD) has continued to gain traction as a viable method for achieving safety in construction due to its ability to address safety issues right from the project’s design phase. However, despite the existing discourse on the potential of PtD, evidence of its application in the delivery of safe construction projects in South Africa is still limited. Therefore, this study explored PtD as a proactive approach toward ensuring safety on construction sites in South Africa.

The study adopted a post-positivist philosophical stance using a quantitative research design and a structured questionnaire as the instrument for data collection. Built environment professionals involved in the design and delivery of construction projects were surveyed, and the data analysis was done using frequency, mean score, the Kruskal–Wallis H-Test and confirmatory factor analysis in EQS 6.4.

The study found a high awareness of PtD practices, albeit a moderate level of implementation. All 14 PtD practices assessed were considered significant to achieving safety within the South African construction industry. However, their implementation is challenged by the poor safety culture, budget constraints to implement safety practices, lack of PtD education and training, absence of supporting policies and standards and deficiency in designers’ skills and understanding of PtD, among others.

By strategically integrating the identified PtD practices in the design phase of construction projects in South Africa, safety risks can be mitigated and a culture of accident prevention can be achieved. The study also provides a foundation for future studies in South Africa seeking to explore proactive prevention of accidents in construction projects through PtD – an aspect that has gained less attention in the South African construction safety discourse.

Technologies have had a positive impact on the construction industry. Technologies such as BIM, automation, augmented and virtual reality, Internet of Things and robotics have been adopted by construction firms to enhance productivity. However, not much research has been done on the awareness and adoption of wearable technologies for health and safety (H&S) management. This paper investigates the level of awareness and adoption of wearable technologies for H&S management in the Nigerian construction industry.

A quantitative research method was adopted for the study. An electronic questionnaire format was used as an instrument to collect the data. Both descriptive (mean score) and inferential statistics (Kruskal–Wallis test) were used to analyse the data.

The results indicate that organisations rarely use H&S wearable devices for H&S management although professionals within the construction industry are somewhat aware of the common H&S wearable devices. The findings further indicate that all 11 variables were perceived as “rarely adopted”, whereas 2 variables were perceived as “aware”, 3 variables as “slightly aware” and the remaining 6 variables as “somewhat aware”.

Data were collected from only construction professionals working in government agencies, consultancy firms and grade D contracting firms in Lagos and Abuja. For a broader perspective, a study that expands the number of states and categories of construction firms is recommended.

The construction industry in Nigeria can use the recommendations to improve H&S management on site. Moreover, the recommendations can contribute to the development of policies to promote the adoption of wearable technologies in construction sites.

Research on wearable technologies, particularly in the Nigerian construction industry, is at the developing stage. With this article, the authors contribute to the body of knowledge in this area of research.

This study investigates the relationship between leaders' ethical behaviors and internal whistleblowing among hotel employees through the mediation role of organizational virtuousness. According to the conceptual framework, ethical leadership creates a virtuous workplace and encourages whistleblowing.

A survey approach with responses of 442 employees from Egyptian five-star hotels was used. Structural equation modeling (SEM) was used to test the hypotheses proposed based on leader–member exchange (LMX) and ethical leadership theories.

Ethical leadership has a favorable impact on organizational virtuousness and, as a result, has a significant impact on whistleblowing intention. The ethical leaders–subordinates' intents to whistleblow association partially mediated organizational virtuousness. To assist them in reporting ethics violations, most hotel employees require organizational characteristics, such as organizational climate and psychological empowerment, in addition to individual characteristics, such as moral bravery and ethical efficacy.

The conceptual framework of this paper adds a new guide for future research related to the hospitality literature, which is how employees' intent to internal whistleblowing. As such, senior management should serve as a moral role model for hotel employees, inspiring them to be moral and allowing them to participate in decision-making.

本研究擬透過組織德行所扮演的仲介角色，去探討領導者的道德行為與酒店員工間內部舉報的相互關係。根據有關的概念框架，領導倫理會為機構創造一個富有道德的工作場所，以及鼓勵員工互相舉報不當的行為。

研究採用調查方法進行，數據來自442名於埃及五星級酒店工作的僱員的回覆。研究人員以結構方程模型來測試研究的假設 － 研究的假設乃根據領導者－成員交換理論和倫理型領導理論而提出的。

領導倫理會給組織美德帶來積極的影響，因此，領導倫理也會給舉報動機帶來重要的影響。領袖－下屬舉報合夥人合乎道德的動機，對組織美德起著仲介作用。若要酒店僱員舉報違反道德規範的行為，除了僱員須有個人特質、如道德勇氣和倫理效能等之外，酒店亦須具備一些組織特徵、如組織氛圍和心理賦權等。

本研究的概念框架，給探討僱員作內部舉報行為的動機的學者提供新的指引，為餐旅業的研究提供方向。組織的高級管理人員應以身作則，為僱員建立道德典範，鼓勵他們遵循道德規範而行事，並容許他們參與決策。

Health technologies are advancing rapidly and becoming more expensive, posing a challenge for financing healthcare systems. Health technology assessment (HTA) improves the efficiency of resource allocation by facilitating evidence-informed decisions on the value of health technologies. Our study aims to create a customized HTA roadmap for Oman based on a gap analysis between the current and future status of HTA implementation.

We surveyed participants of an advanced HTA training program to assess the current state of HTA implementation in Oman and explore long-term goals. A list of draft recommendations was developed in areas with room for improvement. The list was then validated for its feasibility in a round table discussion with senior health policy experts to conclude on specific actions for HTA implementation.

Survey results aligned well with expert discussions. The round table discussion concluded with a phasic action plan for HTA implementation. In the short term (1–2 years), efforts will focus on building capacity through training programs. For medium-term actions (3–5 years), plans include expanding the HTA unit and introducing multiple cost-effectiveness thresholds while from 6–10 years, publishing of HTA recommendations, critical appraisal reports, and timelines is recommended.

Although the HTA system in Oman is still in its early stages, strong initiatives are being taken for its advancement. This structured approach ensures a comprehensive integration of HTA into the healthcare system, enhancing decision-making and promoting a sustainable, evidence-based system addressing the population’s needs.

This final chapter, presented by the book’s three Editors, provides a reflection and discussion of the key findings presented throughout the book. First, it delves into the book’s vision and the process of creation. The findings in the book affirm the continuous growth of the field, highlight the diverse nature of the RMA landscape, and reveal the substantial variation in the status of the profession and the availability of data among regions and countries. To understand the unique features of the RMA profession from multitude of angles and in each country’s context, the Editors emphasize the importance of inviting authors to share their perspectives in their own voices and styles, which became central to the book’s mission. Second, this chapter presents discussions on pivotal findings in four areas: (1) growth of the RMA profession in specific countries and regions, (2) crucial contribution of professional associations to advancing RMA, (3) essential soft skills for RMAs and promotion of diversity, equity, and inclusion, and (4) advancing RMA through increasing training and capacity-building initiatives. This chapter also alludes to potential policy implications and concludes with the Editors’ hope that the book serves as a catalyst for further exploration of the RMA field and RMA professions.

The research aims to test the links amongst Meyer and Allen's three levels of organisational commitment and the commitment's effect on reducing turnover intentions for Islamic bank (IB) employees during the lockdown caused by coronavirus disease (COVID-19).

The research follows a variable-centred approach. Primary data are collected through a survey of 324 respondents comprising IB employees from three Arab countries, notably the United Arab Emirates (UAE), Lebanon and Oman. Exploratory factor analysis (EFA) and Cronbach's alpha test are conducted to test the construct validity, reliability and internal consistency of collected data. Descriptive statistics are used to interpret the data. Zero-order correlations, multiple regression analysis and Fisher's Z-test are applied to assess the interrelations of the various groups of variables and the determinants of turnover intentions.

Results show that there is a high level of significant intercorrelation amongst affective, normative and continuance commitments as well as amongst organisational commitment, individual differences and turnover intentions for IB employees from the three studied Arab countries. The results confirmed that turnover intentions are minimised in the presence of all three organisational commitment subscales and that individual differences amongst IB employees and organisational efficiency moderate the relationship between organisational commitment and turnover intentions.

There is no empirical work that has been done on the determinants of turnover intentions amongst IB employees during the lockdown. This is valuable to organisational behaviour scholars and practitioners who are interested in the role that organisational commitment plays in IB's employment behaviour.
