Abstract

Purpose

The purpose of this paper is to investigate the combined effect of wear and turbulence on the performance of a hydrodynamic journal bearing operating under Newtonian and couple stress fluids (CSF).

Design/methodology/approach

The analysis consists of a modified Reynolds equation of incompressible thin viscous films, and the film thickness model taking into account the wear effect. The governing equation was solved numerically using the finite difference approach.

Findings

The effect of both the wear parameter and the local Reynolds number on the performance characteristics of bearing has been presented and discussed. The obtained results observed that the characteristics of the intact and worn bearing in turbulent and laminar have been enhanced due to the non-Newtonian fluid (CSF) effect. Also, the results display that bearing worn and the turbulent regime cannot be neglected in calculating the performance characteristics of the bearing lubricated with Newtonian and non-Newtonian fluids. The results achieved from this study, specify that the bearing characteristics are significantly affected by these effects.

Originality/value

The paper investigates the behavior of hydrodynamic bearings considering different aspects simultaneously is interesting, and the application meets the current needs of improvement in modeling hydrodynamic bearings under different conditions.

Abstract

Purpose

The purpose of this paper is to explore the perceptions of operating room staff towards the use of the World Health Organization Surgical Safety Checklist in a tertiary hospital in Jordan.

Design/methodology/approach

This was a qualitative descriptive study. Semi-structured interviews were conducted with a purposeful sample of 21 healthcare staff employed in the operating room (nurses, residents, surgeons and anaesthesiologists). The interviews were conducted in the period from October to December 2021. Thematic analysis was used to analyse the data.

Findings

Three main themes emerged from data analysis namely compliance with the surgical safety checklist, the impact of surgical safety checklist, and barriers and facilitators to the use of the surgical safety checklist. The use of the checklist was seen as enabling staff to communicate effectively and thus to accomplish patient safety and positive outcomes. The perceived barriers to compliance included excessive workload, congestion and lack of training and awareness. Enhanced training and education were thought to improve the utilization of the surgical safety checklist, and help enhance awareness about its importance.

Originality/value

While steps to utilize the surgical safety checklist by the operation room personnel may seem simple, the quality of its administration is not necessarily robust. There are several challenges for consistent, complete and effective administration of the surgical safety checklist by the surgical team members. Healthcare managers must employ interventions to eliminate barriers to and offer facilitators of adherence to the application of the surgical safety checklist, therefore promoting quality healthcare and patient safety.

Abstract

Purpose

Under a gradual long-term plan of the Saudi Stock Market (TADWUAL) from 2016, Saudi Arabia decided to work with International Financial Reporting Standards (IFRS) board to fully adopt its accounting standards. Saudi Arabia has undergone several reforms in governance and standards of internal controls are changing rapidly. This study aims to assess whether IFRS adoption has any moderator role in the relationship between disclosure quality and firm-specific characteristics in the Saudi Stock Market.

Design/methodology/approach

This study assesses whether IFRS adoption has any moderator role in the relationship between disclosure quality and firm-specific characteristics in the Saudi Stock Market. The key research hypotheses postulate that compared to IFRS status, after adoption, several independent variables influence the disclosure level. The analysis covers a local sample of 184 Saudi listed firms over the period 2016 to 2020. Using an in-depth content analysis technique, the voluntary disclosure and number of annual report pages are measured manually and year by year to capture levels and unique characteristics. The authors apply cross-sectional regression, first difference method, Pooled OLS and feasible general least square estimations. The mean of disclosure level increases from 33.03% in 2016 to 56.14% in 2020.

Findings

The results reveal that the vast majority of firm-specific characteristics were significant in pre-IFRS adoption period. First difference analysis shows a significant impact of firm size and non-executive composition on the disclosure level. The authors confirm that IFRS adoption plays a critical role in the quality of firms’ financial reports and supports to create a conducive economic environment in Saudi Arabia.

Practical implications

First, the implementation of IFRS adoption should impact the Saudi accounting information and disclosure quality in Saudi context markedly. Second, firm-specific characteristics align with corporate governance are the main determinants of accounting information and transparency; therefore, focusing on this angle enables regulators and policymakers to mitigate uncertainty and asymmetric information. Third, the findings of this research state that there is a negative relationship between disclosure quality and board meetings. This encourages policymakers to reconsider the number of board meetings in firms that was not as high as in the developed markets. Notwithstanding all previous implications, it is recommended that future research undertake a various quasi-experimental design such as a difference-in-difference approach to estimate the causal effect of corporate governance mechanisms on IFRS 7 mandatory disclosure requirements on in Saudi Arabia context.

Social implications

There is a lack of studies on this realm and such as these studies will enrich the understanding of aspects of IFRS adoption and contribute to the prior empirical literature. Importantly, the extend of this sample into other Gulf Cooperation Council countries and exhibition the difference effect can be very useful to enrich the knowledge of IFRS adoption aspects in corporate disclosure and accounting information quality.

Originality/value

Saudi Arabia has undergone several reforms in governance, and their standards of internal controls are changing rapidly. This has been attributed to the importance of providing guidelines, practices and regulations for listed companies. One of the major turning points of financial reporting quality in Saudi listed firms was adoption of IFRSs. This adoption deems to be necessity in ensuring the highest level of transparency and information reliability. Based on the findings of this research, the present investigations set up a platform and furnish many implications for policymakers, companies’ board of directors, financial analysts and other related authorities. The results should provide policymakers with greater insight of the relationship between disclosure quality and corporate-specific characteristics throughout the IFRS adoption periods. Thus, the results derived from this study can be effective and useful for the IFRS adoption committee in the Saudi Organization for Certified Public Accountants (SOCPA). According to the best of the authors’ knowledge and based on official secondary information sourced from the SOCPA website, there are several standards that are subject to difficulties in measurement and are modified from time to time, such as: IFRS1, IFRS8, IFRS12, IFRS16 and IFRS18.

Abstract

Purpose

Construction is a risky industry. Therefore, organizations are seeking ways towards improving their safety performance. Among these, the integration of technology into health and safety leads to enhanced safety performance. Considering the benefits observed in using technology in safety, this study aims to explore digital technologies' use and potential benefits in construction health and safety.

Design/methodology/approach

An extensive bibliometrics analysis was conducted to reveal which technologies are at the forefront of others and how these technologies are used in safety operations. The study used two different databases, Web of Science (WoS) and Scopus, to scan the literature in a systemic way.

Findings

The systemic analysis of several studies showed that the digital technologies use in construction are still a niche theme and need more assessment. The study provided that sensors and wireless technology are of utmost importance in terms of construction safety. Moreover, the study revealed that artificial intelligence, machine learning, building information modeling (BIM), sensors and wireless technologies are trending technologies compared to unmanned aerial vehicles, serious games and the Internet of things. On the other hand, the study provided that the technologies are even more effective with integrated use like in the case of BIM and sensors or unmanned aerial vehicles. It was observed that the use of these technologies varies with respect to studies conducted in different countries. The study further revealed that the studies conducted on this topic are mostly published in some selected journals and international collaboration efforts in terms of researching the topic have been observed.

Originality/value

This study provides an extensive analysis of WoS and Scopus databases and an in-depth review of the use of digital technologies in construction safety. The review consists of the most recent studies showing the benefits of using such technologies and showing the usage on a systemic level from which both scientists and practitioners can benefit to devise new strategies in technology usage.

Purpose

This paper aims to offer a wider examination of the research concerning entrepreneurship characteristics in the Middle East and North Africa (MENA) region via a review of recent studies relevant to this topic. Research publications concerning entrepreneurship within the MENA region evidence growing interest in this field of study, with the potential to boost and drive future economic development and growth. This focus within entrepreneurship research is because of the economic development in the region, which is becoming increasingly important for policymakers and businesses.

Design/methodology/approach

The author performed a systematic literature review to produce robust information about entrepreneurship in the MENA region, followed by a thematic analysis to identify key research themes within each category.

Findings

Despite the growth in entrepreneurship research in the MENA region, research on certain factors is lacking. An analysis of 271 studies published between 2009 and 2019 identifies 9 main research categories, within which 30 themes have attracted significant academic attention. Female entrepreneurship and gender, youth entrepreneurship and entrepreneurship behaviour and orientation are the three key categories influencing perspectives on entrepreneurship in the MENA region. This study highlights research gaps and provides recommendations to guide future research on the sustainable development of entrepreneurship in the MENA region.

Originality/value

This paper highlights trends in entrepreneurship research amongst scholars within the MENA region and suggests paths for future research efforts.
