This classroom-based qualitative study explored the effectiveness of the debate learning strategy in female postgraduate education in Saudi Arabia, which is implementing its recent national development plan, Vision 2030. Educational reform is key to its transition to a modernized, knowledge-based economy. The debate format was used to elicit views on educational reforms and necessitated forming and articulating well-reasoned arguments and logic.

At a Saudi Eastern Province university, 13 female postgraduate students (preservice teachers) participated in a student-centered learning environment conducive to debates. Documents prepared for the debate underwent a qualitative content analysis.

Data were readily classified into five categories: educational reforms should meet 21st century skills, achieve educational outcomes, ensure Saudi Arabia’s knowledge-based economy, prioritize the role of the university and recognize the impact of both teachers and curricula. As key players in the nation’s future, participants affirmed the ongoing need for educational innovation and modernization.

While debates are an authentic part of Arabian heritage, they are less utilized in Saudi higher education settings. Findings affirm that debates are a beneficial learning strategy for bolstering future educators’ participation in Saudi Arabia’s educational reform.

As structural members, circular helicoidal bars are frequently used in the construction industry for a variety of practical and/or aesthetical reasons. While these bars (curvilinear beams) might represent the most practical alternative for carrying loads in a specified structural configuration, the three dimensional structural response has been found to be superior compared to that of other forms of structural members under a general state of loading. Presents the results of a study that has been designed to investigate the free vibration characteristics of this type of bar. The study reported is limited to the analysis of free vibrations utilizing the method of dynamic transport matrix (DTM), and the finite elements method (FEM). A comparative study of the results provided by the DTM is presented to assess the vibration characteristics of circular helicoidal bars and circular bars. The results indicate: the inherent structural superiority of the three dimensional behaviour of circular helicoidal bars; and the computational efficiency of the DTM as compared to the FEM.

This study attempts to identify and explicate the unique segmentation of the increasingly growing virtual reality (VR) user market based on the user experience. Consequently, it collects five hundred forty-five online survey questionnaires through the Prolific platform and deploys cluster analysis to identify mutually exclusive groups of VR users. The research variable, user experience, contains 16 indicators explained by four dimensions. As a result, this study is able to unveil three mutually exclusive markets which are labeled as (1) beginner, (2) aficionado, and (3) utilitarian. The unique features of these three groups are further compared based on their VR tour behaviors. In the conclusion section, it offers managerial implications for devising novel marketing strategies.

This paper aims to consider the heat transportation together with irreversibility analysis for the flow of couple stress hybrid nanofluid past over a stretching surface. The innovative characteristics of this paper include electro-magnetohydrodynamic (EMHD) term, viscous dissipation, Joule heating and heat absorption\omission. The hybrid nanofluid is prepared due to the suspension of the solid nanoparticles of the single wall and multi-wall carbon nanotubes (SWCNTs and MWCNTs) in the blood for the testing purpose of heat transfer and drug deliveries. The experimental value of the Prandtl number used for the blood is 21 from the available literature and very large as compared to the Prandtl number of the other base fluids. Appropriate transformations are incorporated to convert the modeled partial differential equations into the nonlinear ordinary differential equations. The homotopy analysis method (HAM) is used to obtain the solution. The explanation for velocity, energy and entropy are exposed under the influence of various parameters such as E, M, k, Q, S and Ec. The numerical values are calculated and summarized for dimensionless Cf and Nu.

The numerical values are calculated and summarized for dimensionless In addition, the current study is compared for various values of to that published literature and an impressive agreement in terms of finding is reported. It has also been noticed that the and factors retards the hybrid nanofluid flow, while the temperature of fluid becomes upsurges by the rise in these factors.

This is examined while evaluating the previously discussed publications that study on EMHD aspects of magnetized Casson type hybrid nanofluid via entropy generation research is innovative but also acknowledging that the couple stress model challenged bilaterally on stretching surface has not yet been studied. So, there is an ongoing attempt to bridge such a space.

Presents two sequential preventive maintenance (PM) models. The first model can be viewed as an extension of Nakagawa’s model where the age reduction of the system is assumed to depend on the level of PM activities. Linear and nonlinear relationships between age reduction and PM level have been considered. In the second model, a sequential PM model is developed in which PM intervals are defined such that the integrated hazard rate over each interval is the same for all intervals. This restriction reduces the number of decision variables from N + 2 to only three decision variables, where N is the number of intervals between PMs. The cost difference between these two models was very small for the examples solved. This provides evidence that the integrated hazard rate restriction provides a very good approximation of this sequential PM model. This suggests that the integrated hazard rate condition may be used to reduce greatly the number of decision variables at the expense of a reasonable increase in the expected total cost.

The purpose of this paper is to explore the link between earnings quality, Audit Committees and the Board of companies located in Jordan through the lens of enhancing corporate governance.

The real earnings management (REM) and accruals earnings management models were notably used within the panel data robust regression analysis approach; these were used against certain Audit Committee characteristics (i.e. meeting frequency, amount of Board and Committee participants [both internal and external], size) and Board of Directors.

The former characteristics were found to have a positive relationship with REM, while the latter yielded mixed results: while there was no significant identifiable relationship between Board outsiders and REM, there was a positive relationship identified between Board meetings, Board insiders and Board size and REM. In regard to this study’s limitations, the qualitative data gathered for the Board of Directors through the lens of corporate governance enhancement should have been documented with more detail; furthermore, the study was limited to the study of just one nation.

The data is limited to only a single country. More explanation for Board of Directors need qualitative understandings into corporate governance improvement. The control variables are essentially partial in a developing market context.

The different corporate governance code and guidelines improvements have varied influence on earnings quality. As predictable, boards of directors most effect on earnings quality. Improvements have included most modification to audit committees but through them slight measured effect on earnings quality.

Jordan’s corporate governance improvements expected organised corporate governance practices generally in place amongst its boards, and though invoking considerable modification to audit committees, eventually included slight modification to earnings quality. However, both improved earnings quality.

This particular research appears to be the first to consider both Audit Committee and Board of Directors characteristics in one model; indeed, in this vein, this research is also the first to explore the corporate governance enhancements that initially stemmed from there being zero code or guideline regarding its use, despite it becoming required recently. Hence, the authors can say this study has high originality.

The main purpose of this paper is to investigate the effect of performance appraisal mechanisms on employee productivity in public hospitals in Mbeya – Tanzania, when mediated by working environment and management style.

Using a sample of 338 employees, a cross-sectional design was adopted; questionnaires and interviews were used to collect primary data. Partial least squares structural equation modelling (PLS-SEM) was used to determine the relationship between the variables, and Sobel’s test was performed to test the mediation effects.

Astudy found a strong association between performance appraisal mechanisms and employee productivity (p < 0.05). Goal setting significantly enhanced employee productivity (p < 0.05). Performance planning negatively impacted employee productivity, especially when combined with the working environment (p < 0.05). Assessment criteria had a significant positive effect on employee productivity when mediated by working environment and management style (p < 0.001).

This is the first study to examine how a performance appraisal system influences the productivity of public hospital employees in Tanzania. The study further explores the potential mediating effects of the work environment and management style on this relationship. By analysing the interplay between these variables and their impact on productivity, organizations can develop targeted strategies to boost employee performance and achieve superior results.

Purpose: Blockchain is the most significant technological innovation of the generation following the internet. However, most individuals are unaware of how it will affect the insurance business.

Design/methodology/approach: The present study utilises a systematic review methodology to assess the existing literature on blockchain technology in the insurance industry.

Findings: Currently, few insurance companies are researching and using blockchain technology for automated claims, fraud detection, and cash flow tracking. The use of blockchain technology in the insurance business is still in its early stages, and many significant issues remain unsolved. This chapter lays out the discussions regarding the current state of blockchain technology in the insurance business.

Practical implications: Using distributed ledger technology (DLT), all the stakeholders can easily exchange the relevant information on a real-time basis. In particular, blockchain technology will help all insurance companies minimise discrepancies related to fraudulent claims by keeping track of the customer’s history of the customer reducing administrative costs.

Originality/value: It has been observed that very few studies have been conducted in this field. This is a holistic study that focuses on the applications of blockchain technology in various non-life insurance segments.

The study aims to examine the effect of multiple directorships on accrual-based earnings management and real earnings management. It analyses whether earnings management practices in the Saudi context increase or decrease with the average number of multiple directorships.

The study uses the approach by Roychowdhury (2006) to capture the level of real earnings management and uses the cross-sectional model by Jones (1991) to measure accrual-based earnings management.

The paper provides partial evidence supporting the “busyness” hypothesis where earnings management practices increase with the number of multiple directorships. The evidence shows that multiple directorships have a positive and significant effect on real earnings management in the Kingdom of Saudi Arabia. However, we find no significant impact of multiple directorships on accrual-based earnings management.

This is the first study that empirically investigates the relationship between multiple directorships and earnings management in the Kingdom of Saudi Arabia. The paper contributes to the limited literature on multiple directorships in developing countries by examining their impact on opportunistic real earnings management.
