Abstract
Learning can be viewed as a communication process that puts the learner in contact with concepts created by others. A result of communication is that an act of interpretation starts, which invokes a process of conceptualization. According to Mayes, successful conceptualization will need the support of learning activities. Hence, machine mediated communication is important for creating online e‐Learning opportunities; not only for relaying communication content, but also for supporting the cognitive processes associated with the necessary learning activities required for conceptualization. In Laurillard’s conversational theory, a communication loop should be established between learners and teachers. The articulation element in this loop is necessary for engaging the learner in a collaborative activity, which is essential for developing further the conceptualization process. This paper discusses the acts of communication, conceptualization and articulation within a machine mediated multimodal communication, and it proposes a framework within which a supporting set of cognitive activities can be developed.

Abstract
Purpose
This paper aims to present an epistemological perspective of how web mining can be performed by human agents, and a technical overview of a possible approach to achieve this.
Design/methodology/approach
The concept of visual mining of information is based on the principle of creating a fused information space that could be navigated using visual perception, just as is possible within a natural environment. It is argued that, as the information available through human‐created artefacts increases, conventional methods of information acquisition will fail to circumvent the bottle‐neck created by the associated information overflow.
Findings
Four types of human‐created artefacts are identified: cognitive externalisations, artistic expressions, communicative accounts, and factual records. It is the communicative artefacts that are responsible for the information overflow. As a possible way forward, it is suggested that an information space could be constructed in two layers: a perceptual layer and a cognitive layer. The information in the perceptual layer could be encoded in iconic cues to create an information landscape that could be navigated visually. The cognitive layer, on the other hand, will operate on the information‐engendering data structures of the communicative artefacts.
Practical implications
When developed, the perceptual layer could provide a subject domain landscape that induces social familiarity with frequently traversed information environments. This should be particularly helpful for learning where frequent traversal provides opportunities for repeated rehearsal, a necessary condition for long‐term retention.
Originality/value
The objective of this paper is to facilitate a shift in cognitive loading associated with knowledge acquisition from post‐perceptual to perceptual operations. The appealing nature of perceptual processing underpins the claim about enhancing long‐term retention.

Abstract
Purpose
The purpose of this study was to investigate the polyacrylic polymer/Al2O3 as a new nanocomposite coating to protect brass and Al-bronze in 3.5% NaCl and the role of alumina formulation on their protection efficiency
Design/methodology/approach
The corrosion efficiency of the nanocomposite coating (NCC) was evaluated by open circuit potential and electrochemical impedance spectroscopy (EIS).
Findings
The protection efficiency was more in the case of Al-bronze even for the same formulation of alumina NCC indicated the Cu substrate contribution. The Cu oxides in alloys and Al2O3 from the NCC and Al-bronze were responsible for this protection.
Originality/value
All the techniques supported each other, the presence of alumina was responsible for the corrosion protection efficiency.

Abstract
The chapter aims to investigate the link between COVID-19 and Islamic finance, investigating how Islamic countries respond to the impact of the pandemic and how Islamic banks have responded in consideration of their financial statements. The study proposes a novel perspective based on thematic analysis of blogs and newspapers to validate the relevant literature. Moreover, the documentary analysis will allow researchers to investigate Islamic banks' financial statements. We find that Islamic countries have used extraordinary Sukuk issuances both at government and cross-border level. Moreover, traditional instruments such as the Zakat have been converted for even more social uses. Concerning the literature, we find that there have been temporary tax suspensions and commodity supply measures to deal with the pandemic crisis's uncertainty. Finally, financial statements analysis reveals prudent behaviour with decreases in profits aimed at increasing risk provisions. The results provide theoretical evidence to researchers and practical evidence to policymakers, public policy investors and citizens.

Abstract
Purpose
This paper aims to assess the efficiency of emulsified essential oils in glycerol as eco-friendly antimicrobial and plasticized agents added to the biopolymer of gelatin for lining historical oil paintings on canvases.
Design/methodology/approach
Cedar oil, cinnamon oil and their mixtures were emulsified in glycerol and incorporated into gelatin adhesive as green biocides and plasticizers. Physical, biological, chemical and mechanical tests were conducted on experimental mock-ups to assess the gelatin-based adhesive formulations for the reinforcement of canvas supports. Scanning electron microscope, colorimetric measurements, antimicrobial activity test, attenuated total reflection-Fourier transform infrared spectroscopy, tensile strength and elongation tests were carried out on the mock-ups before and after the artificial aging.
Findings
The formulations of gelatin-based adhesive with cinnamon and cinnamon-cedar mixture emulsified in glycerol proved their efficiency on the antimicrobial activity test, chemically delaying the decomposition of gelatin and accordingly providing compatible mechanical properties. Gelatin-based adhesive with emulsified cinnamon oil showed a slight yellowing that was quite improved with the mixture of the cinnamon-cedar-based adhesive formulation.
Originality/value
This study promotes a green approach to lining historical oil paintings by developing green formulations from bio-based origins that minimize the shrinkage and microbial infection of gelatin for lining paintings.

Abstract
Purpose
This paper aims to investigate feedback trading and autocorrelation behavior in the cryptocurrency market.
Design/methodology/approach
It uses the GJR-GARCH model to investigate feedback trading in the cryptocurrency market.
Findings
The findings show a negative relationship between trading volume and autocorrelation in the cryptocurrency market. The GJR-GARCH model shows that only the USD Coin and Binance USD show an asymmetric effect or leverage effect. Interestingly, other cryptocurrencies such as Ethereum, Binance Coin, Ripple, Solana, Cardano and Bitcoin Cash show the opposite behavior of the leverage effect. The findings of the GJR-GARCH model also show positive feedback trading for USD Coin, Binance USD, Ripple, Solana and Bitcoin Cash and negative feedback trading for Ethereum and Cardano only.
Originality/value
This paper contributes to the literature by extending Sentana and Wadhwani (1992) to explore the presence of feedback trading in the cryptocurrency market using a sample of the most active cryptocurrencies other than Bitcoin, namely, Ethereum, USD coin, Binance Coin, Binance USD, Ripple, Cardano, Solana and Bitcoin Cash.

This paper aims to examine the factors affecting the implementation of corporate social responsibility (CSR) sustainably in mobile operators in the kingdom of Bahrain.
Abstract
Purpose
This paper aims to examine the factors affecting the implementation of corporate social responsibility (CSR) sustainably in mobile operators in the kingdom of Bahrain.
Design/methodology/approach
The research relies on the existing literature as a secondary data source. The primary data was collected through questionnaires distributed to three leading mobile operators in the Kingdom of Bahrain. The research's population numbered 1,689, and the sample size was 313; the simple random sampling method was used for data collection with a response rate of 87.2% out of a total sample size of 273 respondents. In addition, the responses were analyzed using statistical package for the social sciences (SPSS) software version 24.0; specifically, Spearman's rank correlation was used to test the hypotheses. The research design was quantitative, so a nonparametric procedure was applied to test the hypotheses.
Findings
The research produced positive relationships between the independent variables (economic, legal, ethical, philanthropic and environmental responsibilities) and the dependent variable: CSR implementation by Bahrain mobile operators; therefore, the five proposed hypotheses were accepted; furthermore, the highest positive correlation coefficient was 0.735 for environmental responsibility, and the lowest correlation coefficient was 0.533 for economic responsibility.
Research limitations/implications
The research produced positive relationships between the independent variables (economic responsibility, legal responsibility, ethical responsibility, philanthropic responsibility and environmental responsibility) and the dependent variable: CSR implementation by Bahrain mobile operators; therefore, the five proposed hypotheses were accepted; furthermore, the highest positive correlation coefficient was 0.735 for environmental responsibility, and the lowest correlation coefficient was 0.533 for economic responsibility.
Social implications
The outcomes of the research mainly suggest that mobile operators assign employees who have been working with the company for more than 7 years to implement CSR; due to their engagement to implement CSR as a sustainable practice more than others with less than 3 years or 3-6 years in Bahrain mobile operators. Besides, the research provides a starting point by which other researchers could investigate CSR in other sectors in the Kingdom of Bahrain.
Originality/value
The research provided a framework for Bahrain mobile operators to assist them in enhancing the implementation of CSR in a sustainable manner, which are economic, legal, ethical, philanthropic and environmental responsibilities.

Abstract
Purpose
This paper aims to examine the impact of environmental, social and governance (ESG) disclosure and firm value (FV), as well as, pinpoints the role of the audit quality (AQ) as a moderating variable on such impact; where the authors hypothesize that AQ modulates the relationship between ESG disclosure and the FV.
Design/methodology/approach
Data of a sample of firms listed on the Egyptian Stock Exchange Market (EGX) were collected over the period of 2017–2021 and analyzed using the regression and 2SLS models.
Findings
The results suggested that: (1) the ESG has a significant positive impact on the FV in the EGX, and (2) AQ has a significant impact, as a moderating variable, on the relationship between ESG disclosure and FV.
Research limitations/implications
The findings would help the Egyptian market authorities in realizing the importance of integrating ESG information within the financial reports of the listed firms. The findings could also help in developing effective disclosure procedures to provide shareholders with useful information.
Originality/value
This paper contributes to the literature regarding the ESG disclosure components and the FV value by considering AQ in testing such relationship.
