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 study examines the benefits and potential applications of integrating augmented reality (AR) technology into landscape design education to create a more rewarding educational environment that provides an interesting learning atmosphere and deepens students' knowledge of the landscape design process.

Design/methodology/approach

Experimental method was conducted on the fourth-year architecture students at Port Said University. The experiment went through the following steps: a mobile-based AR application was designed, some exercises were developed and the students performed them using the application, and a questionnaire was formulated and distributed to the students to examine their feedback on integrating AR into the course.

Findings

The success of the experiment was evaluated based on the students' progress, tracked by the instructor, in the exercises and their feedback acquired from the questionnaire. The study found that the integration of AR with traditional teaching methods is perceived as being useful and having a positive impact on landscape design education.

Originality/value

Lessons learned from this study can help architectural educators in planning to use AR in their curricula to enrich architectural education.

Abstract

Purpose

The purpose of this study is to propose an analytical model that investigates both a direct path between corporate governance quality and earnings quality and an indirect path, in which firms' performance is a mediating variable that is influenced by corporate governance quality and that, in turn, influences earnings quality.

Design/methodology/approach

The study employs a structural equation modelling (SEM), to a sample of Egyptian listed firms during 2011–2017, to test the proposed analytical model and to determine the relative importance of both the direct and indirect paths.

Findings

The findings show a statistically significant evidence of both a direct path from corporate governance quality to earnings quality, and an indirect path that is mediated by firms' performance, suggesting that both corporate governance quality and performance have a complementary effect on earnings quality. However, the weight of the evidence favouring the direct path is more important in case of accounting-based performance measures; and the weight of the evidence favouring the indirect path is more important in case of market-based performance measures.

Research limitations/implications

The current study has some limitations. First, the study focuses specifically on one proxy for measuring earnings quality which is the absolute value of discretionary accruals. Other proxies of earnings quality could be examined in future research, such as income smoothing, earnings persistence and timely loss recognition. Another limitation is that only financial performance measures were examined, namely, return on assets, return on equity, price-to-earnings ratio and market-to-book value. Notwithstanding, non-financial performance measures could be investigated in future studies, such as balanced scorecard (BSC). Furthermore, considering cultural, political and legislative differences among countries, the results may not be generalised outside the scope of the current sample (i.e. Egyptian listed firms).

Practical implications

The implications of the findings for both theory and practice are discussed.

Originality/value

This study is distinguished by validating an analytical model that has been overlooked by prior studies. Moreover, it provides a new constructed index for measuring corporate governance quality. Furthermore, it uses a new sophisticated statistical technique, which is SEM, for testing the proposed model.

Abstract

Purpose

This study aims to examine whether corporate social responsibility (CSR) reporting adds any value to the firm.

Design/methodology/approach

This study uses content analysis to capture the specific CSR-related attributes and to construct a CSR reporting index. The data is manually collected from 115 publicly listed firms on the Dhaka Stock Exchange. The companies audited financial statements were the source of data. This study uses an ordinary least square regression analysis to examine the relationship between CSR reporting and firm performance.

Findings

The results of this study show that firms’ involvement in CSR activities and related reporting has a significant positive influence on firm performance only under an accounting-based performance measure. However, firms’ involvement in CSR activities and related reporting has a significant negative influence on firm performance under a market-based performance measure.

Research limitations/implications

This study is subject to some limitations, such as the subjectivity or judgement associated in the coding process.

Practical implications

The findings of this study imply that firms may be involved in CSR reporting to meet the stakeholders’ expectations, CSR reporting does not necessarily increase the intrinsic value of the firm.

Originality/value

This study supports the stakeholder theory and contributes to the literature on the practices of CSR reporting in the context of developing countries.

Abstract

Purpose

The purpose of this paper is to review research studies on process optimisation and machine development that lead to the enhancement of final products in various aspects of the fused deposition modelling (FDM) process.

Design/methodology/approach

An overview of the literature, focussing on process parameters, machine developments and material characterisations. This study investigates recent research studies that studied FDM capabilities in printing a vast range of materials from thermoplastics to metal alloys.

Findings

FDM is one of the most common techniques in additive manufacturing (AM) processes. Many parameters in this technology have effects on three-dimensional printed products. Therefore, it is necessary to obtain the optimum elements, for example, build orientation, layer thickness, nozzle diameter, infill pattern and bed temperature. By selecting a proper variable range of parameters, the layers adhere strongly and building end-use products of high quality are achievable. A vast range of materials and their properties from polymers to composite-based polymers are presented. Novel techniques to print metal alloys and composites are examined to increase the productivity of the FDM process. Additionally, defects such as shrinkage and warpage are discussed to eliminate the system’s limitations and improve the quality of final products. Multi-axis and mobile machines brought enhancements throughout the process to eliminate obstacles such as staircase defects in the conventional FDM process. In brief, recent developments were identified and a summary of major improvements was discussed in this study for future research.

Originality/value

This paper is an overview that provides information about research and developments in FDM. This review focusses on process optimisation and obstacles in printing polymers, composites, geopolymers and novel materials. Therefore, machine characteristics were examined to find out the accessibility of printing novel materials for different applications.
