Abstract
Inhibitive efficiency of solutions of substituted isoxazole and isoxazoline organic compounds on Fe dissolution in deaerated solutions of 4M HCL using nitrogen gas was studied at 15°C using the steady‐state potentiostatic current‐potential method at a sweep rate of 1 mV/S. Inhibitive efficiencies were calculated at constant time of immersion of the working electrode from the measurement of current densities, icorr µA cm‐2, in the presence and absence of the organic compounds at the corrosion potentials, Ecorr. Inhibitive efficiency, ?, increases as the concentration of the organic compound increases to a certain limit then decreases again. This may be due to stimulation effect in which the solubility of the adsorbate increase with concentration of the organic compounds. In the region, where the organic compounds act as inhibitors, substituted oxazole compounds showing better inhibitive efficiencies, this maybe due to the fact that the presence of double bond between the two carbon atoms in the oxazole unit enhance the adsorption via ?‐electrons and/or to decrease in steric effect. Other factors that have been found to affect the inhibition efficiencies of these substrates are the size and the relative strength of the electron releasing group of R‐substituents on the isoxazole or isoxazoline unit.

Abstract
Corrosion inhibitors represent the most cost effective and flexible means of controlling internal corrosion associated with oil and gas production. Tests were carried out to demonstrate the structure/effect relationships which are effective in controlling the inhibition efficiency. To illustrate this approach, the substituent field effect at the paraposition of 1(Benzyl)1‐H‐4,5‐Dibenzoyl‐1,2,3‐ Triazole (BDBT) on corrosion inhibition has been investigated. Mild steel rotating cylinder electrode in acid media was used in conjunction with Tafel polarization technique, AC impedance measurements and continuous linear polarization resistance method. The nitro group was found to cause a considerable decrease in the corrosion inhibition of the parent compound BDBT. Owing to the induction effects of Br on the aromatic ring the bromo derivative has better inhibition protection than the methyl derivative. The corrosion rate profiles obtained from on‐line polarization technique showed that the inhibition capacity of the studied substituents at the para‐position increases as follows: NO2 < CH3 < Br < H.

Abstract
Purpose
This study aims to consolidate existing research on digital technology in business education, focusing on adoption determinants, theoretical frameworks and implementation challenges.
Design/methodology/approach
A hybrid literature review was conducted. The first phase involved a keyword co-occurrence analysis of 254 Association of Business Schools-ranked journal articles from the Web of Science database to identify key research themes. To deepen the analysis, the second phase included a content analysis of the 24 most globally cited articles, each with a minimum of 65 total global citations.
Findings
The review reveals that studies primarily focus on factors influencing digital technology adoption, including institutional support, perceived usefulness and ease of use. Researchers frequently cite theoretical models such as the technology acceptance model and the unified theory of acceptance and use of technology. Identified challenges include concerns over technology effectiveness, resistance to change and the influence of cultural and generational differences on technology use.
Practical implications
The findings guide educators and policymakers in formulating strategies for effective technology adoption, emphasizing alignment with educational goals and addressing cultural barriers.
Social implications
Understanding generational and cultural impacts enables the creation of inclusive digital education strategies that cater to diverse student needs.
Originality/value
This study synthesizes fragmented literature, offering new insights into the integration of digital technologies in business education.

Abstract
Purpose
The purpose of this study is to investigate the state of undergraduate business statistics education in the Middle East and North Africa (MENA) and assess its alignment with the best practices in equipping business graduates with the knowledge and skills demanded by the labor market.
Design/methodology/approach
A survey of 108 instructors from 80 business schools in 17 MENA countries was conducted to gauge information on the delivery of business statistics courses. The survey results were benchmarked to a proposed framework for best practices in business statistics education.
Findings
The gap analysis identified deficiencies in the delivery of business statistics education in the region as compared to international best practices. This study revealed a need to revise statistics education as part of a comprehensive reform of business education with the aim to meet international quality standards in business education.
Research limitations/implications
The study relied on the self-reported responses of business statistics instructors in MENA. One hundred eight questionnaires were completed, corresponding to a response rate of 40 per cent. Moreover, the study did not measure the effectiveness of teaching and learning in business statistics courses.
Practical implications
Recommendations from the study are intended to guide business statistics instructors in improving the quality of business statistics education through adopting more effective ways to enhance student learning experience and graduate employability.
Originality/value
This study is the first of its kind to investigate and assess the business statistics education in the MENA region.

Abstract
Purpose
The purpose of this study is to explore the influence of the regulatory environment on the efficiency of transparency within Islamic finance practices. It specifically examines how the determination of Shariah compliance, corporate governance and auditing standards is shaped by regulatory frameworks and their effects on the level of transparent financial reporting.
Design/methodology/approach
The research path was defined, and the research hypotheses were evaluated in the model using partial least squares structural equation modeling. The study collected data through structured surveys from 203 respondents.
Findings
The results of the PLS analysis demonstrate that Shari’ah compliance practices enhance transparency by making it difficult to breach ethical or social norms. These practices also infuse the presence of good corporate practices and quality audits that promote a culture of financial accountability, which is key for market and stakeholder confidence. The regulatory environment adds a critical moderating influence in these relationships by providing the oversight and enforcement capability required to ensure uniformity in the application of Shari’ah adherence and set transparency standards across borders.
Originality/value
The findings of this study have practical implications for those who implement policies, develop regulatory structures and study Islamic finance, underscoring the importance of achieving robust governance and regulatory frameworks. However, the study admits weaknesses, such as limited geographical coverage, reliance on preexisting data and the use of a cross-sectional analysis. Future research directions should include longitudinal and cross-comparative designs, the effects of modern technologies and the integration of qualitative methods alongside quantitative ones.
