Abstract
Purpose
This study aims to examine the impact of market-driven policies on adoption and integration of green chemistry into higher education in Saudi Arabia, uncovering challenges and opportunities faced by educators and institutions in promoting sustainable scientific education.
Design/methodology/approach
This study used a grounded theory methodology to explore the integration of green chemistry in Saudi Arabian higher education amid market-driven policies. In-depth interviews were conducted with 22 participants, and data were analyzed using a systematic coding process.
Findings
The study reveals that market-driven policies significantly influence the integration of green chemistry by prioritizing immediate economic returns over long-term sustainability goals. Key challenges include securing funding and aligning green chemistry with traditional curricula. Opportunities to promote sustainability through curricular reform and policy adaptation were identified.
Research limitations/implications
This study is limited to Saudi Arabian higher education, which may affect the generalizability of findings to other contexts.
Practical implications
Insights suggest policymakers should re-evaluate prioritization of short-term economic gains and develop incentives to integrate green chemistry. Institutions are encouraged to invest in faculty development, adopt interdisciplinary approaches and collaborate with industry and government.
Social implications
Integrating green chemistry into higher education promotes environmental stewardship and prepares future generations to address sustainability challenges. Institutions can shape environmentally conscious societies by fostering a culture of sustainability and ethical responsibilities.
Originality/value
This study contributes to discourse on sustainability in education by providing a grounded theoretical analysis of the dynamics between market-driven policies and green chemistry integration, offering insights for policymakers, educators and researchers.

Abstract
Recent studies in education attempt to ‘criminologise’ some of the current practices and policies of higher education institutions – that is, to deconstruct certain philosophies and practices which may be discriminatory, offensive, and biased to certain social groups. Recent theoretical frameworks problematize current higher education policies, many of which are taken for granted. This paper adopts a critical perspective, shedding light on some practices as they occur in higher educational institutions, by human and non-human agencies. The study applies a ‘detective’ approach examining some problematic uses of technology a higher education institution. In this proposed approach, researchers play the role of ‘detectives’, investigating possible breaches of good practice (possibly discriminatory) committed by higher education actors (referred hereafter as ‘defendants’). Most of these offences are committed through the use of educational and institutional technologies. The purpose of this theoretical approach is to empower alienated social groups against such practices by identifying ‘defendants’ and the implications of their acts. The study uses empirical data from interviews, visits, and observations to explain the ways in which defendants respond to the accusations levelled against them by other users of educational technologies. The investigation revealed that technology was used, among many other functions, to manoeuvre around the legal and ethical system serving the interests of some stakeholders. Then, the study categorises these manoeuvres, explaining the legal implications of each category, and recommending consideration of important academic and institutional issues.

Abstract
Purpose
This study aims to examine the effects of cross-flow and multiple jet impingement on conductive panel cooling performance when subjected to uniform magnetic field effects. The cooling system has double rotating cylinders.
Design/methodology/approach
Cross-flow ratios (CFR) ranging from 0.1 to 1, magnetic field strength (Ha) ranging from 0 to 50 and cylinder rotation speed (Rew) ranging from −5,000 to 5,000 are the relevant parameters that are included in the numerical analysis. Finite element method is used as solution technique. Radial basis networks are used for the prediction of average Nusselt number (Nu), average surface temperature of the panel and temperature uniformity effects when varying the impacts of cross-flow, magnetic field and rotations of the double cylinder in the cooling channel.
Findings
The effect of CFR on cooling efficiency and temperature uniformity is favorable. By raising the CFR to the highest value under the magnetic field, the average Nu can rise by up to 18.6%, while the temperature drop and temperature difference are obtained as 1.87°C and 3.72°C. Without cylinders, magnetic field improves the cooling performance, while average Nu increases to 4.5% and 8.8% at CR = 0.1 and CR = 1, respectively. When the magnetic field is the strongest with cylinders in channel at CFR = 1, temperature difference (ΔT) is obtained as 2.5 °C. The rotational impacts on thermal performance are more significant when the cross-flow effects are weak (CFR = 0.1) compared to when they are substantial (CFR = 1). Cases without a cylinder have the worst performance for both weak and severe cross-flow effects, whereas using two rotating cylinders increases cooling performance and temperature uniformity for the conductive panel. The average surface temperature lowers by 1.2°C at CFR = 0.1 and 0.5°C at CFR = 1 when the worst and best situations are compared.
Originality/value
The outcomes are relevant in the design and optimization-based studies for electric cooling, photo-voltaic cooling and battery thermal management.

Abstract
Purpose
This study aims to focus on a thermo-fluid flow in a partially driven cavity (PDC) using Cu-water nanoliquid, magnetic field and porous substance. The cooling and sliding motion are applied on the upper half of the vertical walls and the bottom wall is heated. Thermal characteristics are explored to understand magnetohydrodynamic convection in a nanoliquid filled porous system from a fundamental viewpoint. The governing parameters involved to cater to the moving speed of the sidewalls and partial translation direction are the relative strength of thermal buoyancy, porous substance permeability, magnetic field intensity, nanoparticle suspension and orientation of the cavity.
Design/methodology/approach
The coupled transport equations of the problem are solved using an in-house developed finite volume-based computing code. The staggered nonuniform grids along the x and y directions are used. The SIMPLE algorithm technique is considered for the iterative solution of the discretized equations with the convergence check of the continuity mass defect below 10–10.
Findings
The present study unveils that the heat transfer enhances at higher Ri with the increasing value of Re, irrespective of the presence of a porous substance or magnetic field or the concentration of nanofluid. Apart from different flow controlling parameters, the wall motions have a significant contribution to the formation of flow vortices and corresponding heat transfer. Orientation of the cavity significantly alters the transport process within the cavity. The upward wall velocity for both the sidewalls could be a better choice to enhance the high heat transfer (approximately 88.39% at Richardson and Reynolds numbers, respectively, 0.1 and 200).
Research limitations/implications
Considering other multi-physical scenarios like porous layers, conducting block, microorganisms and the present investigation could be further extended to analyze a problem of complex flow physics.
Practical implications
In this study, the concept of partially driven wall motion has been adopted under the Cu-water nanoliquid, magnetic field, porous substance and oblique enclosure. All the involved flow-controlling parameters have been experimented with under a wide parametric range and associated thermo-flow physics are analyzed in detail. This outcome of this study can be very significant for designing as well as controlling thermal devices.
Originality/value
The convective process in a partially driven cavity (PDC) with the porous medium has not been investigated in detail considering the multi-physical scenarios. Thus, the present effort is motivated to explore the thermal convection in such an oblique enclosure. The enclosure is heated at its bottom and has partially moving-wall cold walls. It consists of various multi-physical conditions like porous structure, magnetic field, Cu–H2O nanoliquid, etc. The system performance is addressed under different significant variables such as Richardson number, Reynolds number, Darcy number, Hartmann number, nanoliquid concentration and orientation of cavity.

This paper aims to study the mixed convective process due to various dynamics, namely, inner rotating cylinders and upper-wavy wall movement for the first time.
Abstract
Purpose
This paper aims to study the mixed convective process due to various dynamics, namely, inner rotating cylinders and upper-wavy wall movement for the first time.
Design/methodology/approach
The Galerkin finite element method together with the characteristic-based split scheme is applied to solve the governing system.
Findings
The main outcomes revealed that the direction of the rotation of the cylinders, radius and locations of the rotating shapes are beneficial controlling elements for the enhancement of heat transfer. Also, for all the considered cases, values of the Bejan number indicate that the fluid friction irreversibility is dominance compared to the heat transfer irreversibility. Further, average values of the heat transfer entropy, fluid friction entropy and total entropy are minimized in the case of fixed cylinders regardless of the cylinder radius.
Originality/value
The authors are interested in the mixed convection case due to regular boundaries and hence this simulation purposes a first attempt to examine the mixed convective flow due to irregular wavy boundaries. This study considered various dynamics, namely, inner rotating cylinders and wavy-lid driven wall which makes it more attractive to the readers. Various cases based on radius of the cylinder and direction of the rotations together with several locations of the rotating shapes are taken into account which makes the current simulation is comprehensive. Various studies presented in this field are made by commercial software and these treatments need special conditions (having limitation) but the current solution methodology is based on a finite element method home-code. Various important impacts, are, also, examined, namely, inclined geometry, inclined magnetic field, thermal radiation and heat generation/absorption. The entropy of the current complex system is analyzed based on the second law of thermodynamics.

Abstract
Purpose
The purpose of this study is to assess the prevalence of burnout syndrome and its associated factors among medical students at Jazan University, Jazan, Kingdom of Saudi Arabia.
Design/methodology/approach
A cross-sectional survey was conducted among 440 randomly selected medical students at Jazan University. The questionnaire used for this study was based on the Copenhagen Burnout Inventory.
Findings
The overall prevalence of burnout was estimated at 60.2% (95% CI 55.6–64.8). The prevalence was higher for females (64.1%) than for males (56.2%) but without statistically significant differences (p > 0.05). On average, the students scored the highest averages in the personal burnout category, followed by the study-related and client-related burnout categories. In the multivariate analysis, a lower age (beta = −3.17, p = 0.026), female (beta = −0.896, p = 0.016), and having better burnout knowledge (beta = 0.710, p = 0.025) predict significantly higher personal burnout.
Practical implications
It is necessary to implement strategies to reduce the incidence of burnout among medical students for the sake of a better quality of life for future doctors.
Originality/value
There is a high prevalence of burnout among Jazan’s medical students.

Abstract
Purpose
This paper aims to study the effect of concentric hot circular cylinder inside egg-cavity porous-copper nanofluid on natural convection phenomena.
Design/methodology/approach
The finite element method–based Galerkin approach is applied to solve numerically the set of governing equations with appropriate boundary conditions.
Findings
The effects of different range parameters, such as Darcy number (10–3 = Da = 10–1), Rayleigh number (103 = Ra = 106), nanoparticle volume fraction (0 = ϑ = 0.06) and eccentricity (−0.3 = e = 0.1) on the fluid flow represent by stream function and heat transfer represent by temperature distribution, local and average Nusselt numbers.
Research limitations/implications
A comparison between oval shape and concentric circular concentric cylinder was investigated.
Originality/value
In the current numerical study, heat transfer by natural convection was identified inside the new design of egg-shaped cavity as a result of the presence of a circular inside it supported by a porous medium filled with a nanofluid. After reviewing previous studies and considering the importance of heat transfer by free convection inside tubes for many applications, to the best of the authors’ knowledge, the current work is the first study that deals with a study and comparison between the common shape (concentric circular tubes) and the new shape (egg-shaped cavity).

Abstract
Purpose
The purpose of this study is to explore the experiences of Saudi Arabian university students returning home after having spent time away studying internationally. The investigation focused exclusively on female students who for diverse reasons were unable to complete their studies abroad.
Design/methodology/approach
A thematic analysis was applied to analyze the seven in-depth interviews conducted by the authors. By using an open coding method analytic patterns across the entire data set were identified and then analyzed.
Findings
The findings suggest that the students experienced reverse culture shock reintegrating and assimilating into their former lives in the Kingdom of Saudi Arabia and its conservative culture. This was especially surprising considering not one of the participants experienced culture shock when they first traveled to their host country – the USA, Canada or England.
Research limitations/implications
The study is limited to a small group of seven female undergraduates who are comparatively well educated and come from a middle and upper socioeconomic demographic. As a result, without additional research, the findings cannot be extended to groups outside of this demographic.
Practical implications
Students who have studied abroad need improved academic and social support networks when they return home, according to the findings. The authors want to raise awareness about the difficulties that students face upon their return. Teachers, counselors, and advisors need to be on the lookout for the symptomatology associated with these types of problems.
Social implications
Female Saudi students returning home after an extended period of study abroad face a variety of problems. They must fit into a restrictive, partriarchal culture in which they are not legally equal to men.
Originality/value
To date, there are no studies that shed light on reverse culture shock for students who returned to Saudi Arabia without a degree. Due to the large number of Saudi scholarship holders who study in English-speaking countries with government support, the study is the first attempt in this direction.

Abstract
Al-Qaeda is conventionally portrayed as a monolithic, hierarchical organization whose activities – coordinated by the network's leader Osama bin Laden – are the source of international terrorism today. Al-Qaeda is considered a radical tendency within the broader Islamist Salafi movement, legitimizing its terrorist operations as a global Islamist jihad against Western civilization. Al-Qaeda's terrorist activity today is considered, “blowback” from long finished CIA and western covert operations in Afghanistan.
The conventional wisdom is demonstrably false. After the Cold War, Western connections with al-Qaeda proliferated around the world, challenging mainstream conceptions of al-Qaeda's identity. Western covert operations and military – intelligence connections in strategic regions show that “al-Qaeda” is a network whose raison d’etre and modus operandi are inextricably embedded in a disturbing conglomerate of international Western diplomatic, financial, military and intelligence policies today. US, British, and Western power routinely manipulates al-Qaeda through a complex network of state-regional and human nodes. Such manipulation extended directly to the 9-11 hijackers, and thus to the events of 9-11 itself.11This paper advances an original argument based partially on research in Ahmed (2005), supplemented here with significant new data and analysis. Also see Ahmed (2002).

Abstract
Corporate Social Responsibility (CSR) Implementation and Disclosure in the Banking Sector: the case of banks with Islamic identity in Syria. This study aims to explore Corporate Social Responsibility Disclosure (CSRD) in Syrian banks which have an Islamic identity, investigating their motivations when implementing and disclosing CSR and the challenges banks have faced. This study employed content analysis to extract knowledge from 33 annual reports published by three banks which have Islamic identity in Syria over the period 2008–2020. Semi-structured interviews were then conducted with five participants who are aware of CSRD policy in the banks in the sample, in order to gain a fuller understanding of their motivations in relation to CSR and any challenges they faced. This article draws on the overlap between Stakeholder and Legitimacy theories in order to explain the motivations of the banks in question. The study found that banks which have an Islamic identity increased their levels of CSR implementation during the conflict crisis but were not publishing details on these activities because of a concern regarding the Islamic modesty around charitable actions and to avoid upsetting the sensibility of beneficiaries. Interviewees commented that in the time of conflict crisis, many Syrians needed relief and support. Because of this, banks in our research sample decided to take responsibility to lessen the negative impact of the conflict crisis on the Syrian community. In addition, the analysis revealed that banks engaged with Environment and Human Right issues after 2013 because they wanted to fulfil the requirements of their national partners.
