Abstract
Purpose
This paper aims to explore the best practices to institutionalize the internal quality of student assessment (SA) when a gap emerges between quality conceptualization and practice work, using Imam Abdul Rahman bin Faisal University (IAU) as a case study.
Design/methodology/approach
A single-embedded case study research design chronologically presents key events of assuring and improving SA at IAU. It integrates quantitative and qualitative data to provide empirical evidence of changes in SA practices.
Findings
Over three years, evident improvements in SA practices resulted in more effective internal quality assurance strategies (e.g., faculty involvement) and the achievement of performance indicators.
Research limitations/implications
This study used data from informal observation and self-reports. Thus, it is suggested that future research should use in-depth (e.g. focus group) and diverse data sources from stakeholders (e.g. students) and use emerging global trends to assess SA quality.
Practical implications
Involving faculty as changing agents via accountability and training in assuring and improving SA quality leads to measurable improvements.
Social implications
A top-down approach alone is insufficient to assure and improve the quality of SA practices, so empowering faculty via involvement and training is inevitable.
Originality/value
The quality assurance of SA described in this practice-oriented case places IAU as a leading university in the region, contributes to the external quality assurance of SA, empowers Saudi graduates to compete in the labor market as aspired in Vision 2030 and adds to the literature on quality assurance of SA in a higher education context.

The purpose of this study is to propose and develop a zakat model for digital assets from the Sharīʿah perspective.
Abstract
Purpose
The purpose of this study is to propose and develop a zakat model for digital assets from the Sharīʿah perspective.
Design/methodology/approach
This research adopts a qualitative research method while studying the literature thoroughly, and it analyzes the data through an exploratory research approach to propose a zakat model for the digital assets.
Findings
This research aims to develop a zakat model for digital assets within the framework of Sharīʿah. Using a qualitative research method, the study thoroughly examines existing literature and uses an exploratory research approach to propose this zakat model. The findings suggest that digital assets hold the potential to be considered for zakat in the contemporary digital age. Previous studies indicate that both commodity-based and currency-based digital assets meet the criteria for zakat imposition. Given zakat’s significant impact on socioeconomic development, it is imperative to carefully manage these assets to maximize their potential benefits. However, variations in interpretations by different jurisdictions and Sharīʿah scholars regarding the understanding and classification of digital assets lead to ongoing scrutiny from legal and religious perspectives. This research aims to contribute to the discourse by proposing a zakat model for digital assets and identifying potential assets eligible for zakat.
Originality/value
This research seems to be the pioneer in providing a zakat model for digital assets, combining different segments of digital assets.

Abstract
Purpose
The purpose of this study is to examine the legal paradigm of multiple Sharia' board directorship practice from the Sharia' law concept of Maslahah Al-Mursalah (public interest).
Design/methodology/approach
It uses a doctrinal research method that relies on the commonly referred sources of Quran and Sunnah, with a specific focus on Maslahah Al-Mursalah and, where applicable, commentaries by contemporary scholars, academics and practitioners as well as translations of classical book of Fiqh. This study scrutinises the polarity of views concerning the distinct Masyaqqah (necessity) surrounding the practice in discussion: the Masyaqqah that encourages and one that discourages the application of the practice.
Findings
This study is keen to suggest the industry to adopt a cautious approach and consider exploring a corporate governance framework that appraises the theoretical and practical Sharia' issues concerning its application in cognisance of its adversarial influence towards the sustainability of Islamic banking industry.
Originality/value
Since Murat Unal’s study of multiple Sharia' board directorships in 2009 and 2011, empirical works that scrutinise the practice from the Sharia' law perspective have remained limited or almost non-existent. It is aspired that this study may assist fellow readers and future researchers alike in evaluating and appreciating the divergent views surrounding the application of this practice in Islamic banking.

Abstract
Purpose
The paper aims to the preparation of novel disperse dye based on azo salicylaldehyde derivatives TF-A [2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde] and full evaluation of their use as disperse dye TF-ASC [bis 2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde Schiff base with 4,4'-methylenedianiline] for dyeing polyester fabric at various conditions.
Design/methodology/approach
The dispersed dye was synthesized via Schiff base condensation in the presence of ceric ammonium nitrate cerium ammonium nitrate 10 mmole% as an eco-friendly catalyst at room temperature. The chemical structure of the prepared dye was characterized via elemental analysis, Fourier-transform infrared spectroscopy, 1H- and 13 C-NMR spectroscopic analysis tools. This study thoroughly examined the dyeing of disperse dye TF-ASC on polyester at various conditions. The characteristics of dyed polyester fabric were measured by colour measurements, as well as light, washing, crock fastness and finally, colour strength. The discrete fourier transform (DFT) theoretical studies, including EHOMO, ELUMO and optimized geometrical structure, were assumed and discussed in detail.
Findings
The results showed that the synthesized organic dye TF-ASC was highly functional and appropriate for this kind of dyeing method. The dyeing fabrics obtained from disperse dye TF-ASC, properties possess high colour strength as well as good overall fastness properties. These dyes had a high affinity for polyester fabric, with just a tiny change in dye affinity when the pH was changed, even under alkaline circumstances. The dye levelness and shade depth of the colour results were good, and there were a variety of hues from light brownish yellow to deep brownish yellow. The results obtained from DFT computational studies such as EHOMO, ELUMO, optimized structure, diploe moment µ and electrophilicity index deduced that prepared organic dye TF-ASC is more applicable as a dispersed dye.
Originality/value
This research is significant because it provides a new dye for dyeing polyethylene terephthalate fibres with exceptional brightness and levelness; the method of preparation is a useful pathway due to its being known as a green chemistry method.

Abstract
Purpose
The purpose of this paper is to investigate the effects of thermal radiation and viscous dissipation on steady natural convection flow of a viscous incompressible fluid along a uniformly moving infinite vertical porous plate with Newtonian heating in the presence of transverse magnetic field. The governing non-linear boundary layer equations are solved by using homotopy analysis method (HAM). The effects of various system parameters on velocity and temperature fields are discussed graphically, and the numerical values for skin friction and Nusselt number are presented in tabular form.
Design/methodology/approach
The problem is formulated using the Boussinesq approximation under the effects of thermal radiation and transverse magnetic field. The resulting coupled system of non-linear differential equations is solved using HAM with appropriate boundary conditions for Newtonian heating of the plate. HAM is a powerful method which provides rapidly converging series solution for the velocity and temperature fields. The effects of Prandtl number, Grashof number, suction parameter, magnetic field parameter, radiation parameter and Eckert number on the fluid velocity, temperature, skin friction and Nusselt number have been investigated.
Findings
The HAM solution has been successfully applied to find the converging series solution for velocity and temperature fields in terms of pertinent system parameters. Comparison of the exact solution results agree well with the HAM solution results in the absence of Eckert number and this indicates that the HAM solutions are accurate. It is found that the velocity and temperature profiles decreases with the increase of thermal radiation and suction parameters. An increase in the magnetic field parameter leads to a rise in the fluid temperature and fall in the fluid velocity.
Research limitations/implications
The present analysis is limited to steady state laminar natural convection flow only. Unsteady natural- /mixed-convection laminar flow in the presence of thermal radiation, chemical reaction and transverse magnetic field will be investigated in a future work.
Practical implications
The study provides very useful information for heat transfer engineers to understand the heat transfer rate when the moving vertical porous surface temperature is not known a prior. The present results have immediate relevance in the design of nuclear reactors where vertical moving porous plates are using as control rods.
Originality/value
The present research work is relatively original and illustrates the effects of thermal radiation, viscous dissipation and transverse magnetic field on natural convection flow past a uniformly moving infinite vertical porous plate with Newtonian heating.

Abstract
Purpose
This study aims to evaluate the nutrient content and acceptable qualities of plant-based burger patties (PBBP) formulated with chickpea flour, defatted sesame cake (DSC) flour, coffee silver skin and pomegranate juice as colorant.
Design/methodology/approach
The chemical composition, energy value, cholesterol content, amino acid composition, cooking loss, pH, color characteristics and sensory attributes of PBBP were analyzed using official procedures and compared to beef burger.
Findings
PBBP had a protein value of 16.0 g/100g, which is nearly close to the protein content of the beef burger (18.1 g/100g). The fat content of the PBBP was approximately three times lower than that of the beef burger. The fiber content in PBBP was approximately 23 times as high as that in beef burgers samples (p = 0.05). The raw PBBP samples supplies 178 Kcal/100g, whereas beef burger possessed 259 Kcal/100g. Neither the raw nor the cooked PBBP samples contained any cholesterol. Both the beef and PBBP displayed acceptability scores higher than 7.0, which suggests that PBBP was well accepted.
Originality/value
It is concluded that the PBBP sample exhibited a protein value of 16.0 g/100g, which is comparable to the protein level of beef burgers (18.1 g/100g). The fat level of the PBBP samples was significantly lower than that of the beef burger samples. Uncooked PBBP samples contained significantly higher fiber content compared to beef burger samples. No cholesterol was found in raw or cooked PBBP samples. Overall acceptance scores for both beef and PBBP samples exceeded 7.0, suggesting that the proposed product (PBBP) was received favorably.

Abstract
Purpose
The purpose of this study is to develop a green corrosion inhibitor (GCI) from the parthenium hysterophorus (PHS) leaf and identifying its efficiency in corrosion inhibition of AZ31 alloy.
Design/methodology/approach
GCI from PHS leaf is extracted with the aid of Soxhlet apparatus and analysed through Fourier transform infrared spectroscopy (FTIR) and phytochemical tests to identify the functional groups and chemical compounds present. Inhibition efficiency (IE) of PHS extract is identified through polarization analysis and immersion tests in which concentration of PHS extract (0–300 ppm) and temperature (303–353 K) is varied.
Findings
Maximum IE of 84% is exhibited by the prepared PHS extract at a concentration of 250 ppm at 303 K and further addition diminishes IE. The developed GCI is found effective in room temperature (303 K) as it exhibits lower IE when temperature increased. Both physical and chemical absorption mechanisms were identified for PHS extract over AZ31 surface, whereas FTIR and SEM analysis confirms the development of passivation layer.
Originality/value
Development of GCI from the leaf of a weed (PHS) that disturbs the ecosystem and identifying its efficiency in preventing corrosion of AZ31 under saline environment.
