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.

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

This study has incorporated competitiveness by considering it a significant factor behind determining as well as moderating industrial value added in the environmental Kuznets curve (EKC) framework. This study aims to explore the moderating role of competitiveness policy in EKC with an aim to promote business led sustainability at national level.

Design/methodology/approach

Considering the environmental deterioration aspect of industrialization, this study tests the existence of EKC for SAARC countries using the data from 1996 to 2021 using second-generation static panel data model.

Findings

Estimated results have validated that moderating effect is responsible for improving environmental sustainability in SAARC countries. Furthermore, population density is responsible for increasing while trade openness is responsible for decreasing carbon emissions.

Originality/value

Higher industrial activities are a symbol of upward-moving economic growth. But its other impact is in the form of environmental deterioration. However, the relationship between industrialization and environmental quality can be identified through EKC.
