Abstract

Purpose

This paper aims to apply a methodology that is capable to classify and localize mechanical, electrical and plumbing (MEP) elements to assist facility managers. Furthermore, it assists in decreasing the technical complexity and sophistication of different systems to the facility management (FM) team.

Design/methodology/approach

This research exploits artificial intelligence (AI) in FM operations through proposing a new system that uses a deep learning pre-trained model for transfer learning. The model can identify new MEP elements through image classification with a deep convolutional neural network using a support vector machine (SVM) technique under supervised learning. Also, an expert system is developed and integrated with an Android application to the proposed system to identify the required maintenance for the identified elements. FM team can reach the identified assets with bluetooth tracker devices to perform the required maintenance.

Findings

The proposed system aids facility managers in their tasks and decreases the maintenance costs of facilities by maintaining, upgrading, operating assets cost-effectively using the proposed system.

Research limitations/implications

The paper considers three fire protection systems for proactive maintenance, where other structural or architectural systems can also significantly affect the level of service and cost expensive repairs and maintenance. Also, the proposed system relies on different platforms that required to be consolidated for facility technicians and managers end-users. Therefore, the authors will consider these limitations and expand the study as a case study in future work.

Originality/value

This paper assists in a proactive manner to decrease the lack of knowledge of the required maintenance to MEP elements that leads to a lower life cycle cost. These MEP elements have a big share in the operation and maintenance costs of building facilities.

Abstract

Purpose

The purpose of this paper is to facilitate the process of monitoring construction projects. Classic practice for construction progress tracking relies on paper reports, which entails a serious amount of manual data collection as well as the effort of imagining the actual progress from the paperwork.

Design/methodology/approach

This paper presents a new methodology for monitoring construction progress using smartphones. This is done by proposing a new system consisting of a newly-developed application named “BIM-U” and a mobile augmented reality (AR) channel named “BIM-Phase”. “BIM-U” is an Android application that allows the end-user to update the progress of activities onsite. These data are used to update the project’s 4D model enhanced with different cost parameters such as earned value, actual cost and planned value. The “BIM-Phase” application is a mobile AR channel that is used during construction phase through implementing a 4D “as-planned” phased model integrated with an augmented video showing real or planned progress.

Findings

The results from the project are then analysed and assessed to anticipate the potential of these and similar techniques for tracking time and cost on construction projects.

Originality/value

The proposed system through “BIM-U” and “BIM Phase” exploits the potential of mobile applications and AR in construction through the use of handheld mobile devices to offer new possibilities for measuring and monitoring work progress using building information modelling.

Abstract

Purpose

Facility management gained profound importance due to the increasing complexity of different systems and the cost of operation and maintenance. However, due to the increasing complexity of different systems, facility managers may suffer from a lack of information. The purpose of this paper is to propose a new facility management approach that links segmented assets to the vital data required for managing facilities.

Design/methodology/approach

Automatic point cloud segmentation is one of the most crucial processes required for modelling building facilities. In this research, laser scanning is used for point cloud acquisition. The research utilises region growing algorithm, colour-based region-growing algorithm and Euclidean cluster algorithm.

Findings

A case study is worked out to test the accuracy of the considered point cloud segmentation algorithms utilising metrics precision, recall and F-score. The results indicate that Euclidean cluster extraction and region growing algorithm revealed high accuracy for segmentation.

Originality/value

The research presents a comparative approach for selecting the most appropriate segmentation approach required for accurate modelling. As such, the segmented assets can be linked easily with the data required for facility management.

Abstract

Purpose

Calcium and Zinc lignates were proven to be good antioxidants for rubber composites. The purpose of this paper is to evaluate the copper lignate antioxidant activity along with evaluating its electrical conductivity in rubber composites.

Design/methodology/approach

The antioxidant activity of the Cu-LSF complex was compared with that of standard commercial antioxidant additives as a green alternative. The rheological characteristics, thermal aging and mechanical and electrical properties were evaluated for the NBR vulcanizates containing the different antioxidants in the presence or absence of coupling agents.

Findings

Results revealed that the Cu-LSF complex (5 phr) can function as a compatibilizing, antioxidant and electrical conductivity agent.

Originality/value

The new copper complex prepared from paper-pulping black liquor of wastes could be used as a green antioxidant and electrical conductivity agent in rubber composites.

This study aims to examine the diametrically opposite effects of probabilistic (risk) and nonprobabilistic uncertainty (ambiguity) on accounting conservatism.

Abstract

Purpose

This study aims to examine the diametrically opposite effects of probabilistic (risk) and nonprobabilistic uncertainty (ambiguity) on accounting conservatism.

Design/methodology/approach

This study uses panel regression models with year and industry-fixed effects. It uses financial and market data from the communication and energy sectors of 24 countries, encompassing 1,946 firms and 5,838 firm-year observations.

Findings

The study reveals that conservatism is a rational response to risk. However, in the presence of higher ambiguity where uncertainty exceeds firm control and outcomes become unpredictable, management reduces conservative accounting practices. Robustness tests support the validity of these findings across different institutional frameworks, agency risks, sample selection and heterogeneity.

Research limitations/implications

This study contributes to the existing literature by exploring the contrasting effects of risk and ambiguity on accounting conservatism. It enhances the understanding of how various institutional factors influence the asymmetric recognition of bad news compared to good news under conditions of uncertainty.

Practical implications

By understanding the role of accounting conservatism in responding to uncertainties, regulators can develop more informed and effective policies that align with the dynamic nature of business environments.

Originality/value

This research provides novel and original ideas suggesting that the change in accounting conservatism is contingent upon the firms’ ambiguity or risk.

Abstract

Purpose

The purpose of this paper is to prepare new disperse dyes and apply for dying polyester fabrics.

Design/methodology/approach

The synthetic reaction was carried out through two steps: preparation of arylhydrazones and alkylation using enaminone and dimethylaminovinyl-pyridazine. The high temperature method was used to apply these dyes to polyester fibres.

Findings

The study revealed that there is a significant effect of the new prepared disperse dyes on polyester fabrics. The structures of the prepared dyes were established based on elemental analysis and spectral data (infra red (IR), mass spectrometry (MS) and proton nuclear magnetic resonance (1H-NMR), carbon 13th nuclear magnetic resonance (13C-NMR)).

Research limitations/implications

Disperse dyes containing heterocyclic moiety have attracted great academic and industrial attention owing to their significant. The potential of using disperse dyes easily prepared from arylhydrazones are promise broad applications for these dyes.

Practical implications

The presence of N-thienyl and N-pyridazinyl in the structure of the synthesised disperse dyes would be expected to add the bioactivity advantage. Also, it can be used in formulating the antimicrobial fabrics.

Social implications

The N-thienyl and N-pyrdiazinyl derivatives of azo dyes are expected to be superior to in the application for fabrics. It may be useful for other applications like painting.

Originality/value

This paper helps to synthesise novel thiophene or pyridazine-based dyestuff for application in dying properties on polyester fabric and study their fastness properties.

Abstract

Purpose

This paper aims to analyse the concept of form over substance and introduces the term substance gap to the literature. The substance gap is defined as the difference between the way a concept is expressed and its intended result. Besides, the study investigates the issue from both classical and contemporary viewpoints.

Design/methodology/approach

The methodology adopted in this paper is descriptive research.

Findings

This paper has depicted the substance gap in contemporary contracts and found that form is equally important as substance in Islamic finance contracts. This paper offers a fresh outlook on form and substance to highlight the importance of the issue and its significance. The findings of the study will help researchers address the issue at its roots and help them to bridge the gap between the form and substance of Islamic finance contracts.

Originality/value

This paper investigates the substance gap in contemporary contracts that exists between the fiqh rules and conditions of an Islamic contract, and their development and construction. Further, the gap could also be attributed to the pressure to cope with a complicated modern finance environment.

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

The paper seeks to explore the factors that would make an impact on the corporate image of large commercial banks in Saudi Arabia through the perceptions of direct customers. It proposes an appropriate way of measuring corporate image in the Saudi banking industry through the development of a questionnaire.

Design/methodology/approach

A questionnaire, presented in English and Arabic, was piloted and tested to a group of banking customers in three major cities of Saudi Arabia.

Findings

Results indicate that three factors significantly influence perception: “financial prospects”, “corporate management” and “corporate communication”. These explain 67.7 per cent of the total variance. The notion of “market presence” was not strongly felt in the Saudi banking industry despite the growing trend of internationalization of large commercial banks in the country.

Research limitations/implications

Corporate image is regarded as a critical, strategic and enduring intangible asset for an organization. A favorable corporate image can be an effective form of differentiation and a source of competitive advantage ensuring long‐term success.

Practical implications

Managing complex customer relationships is a first step in creating better corporate image. Publicity tools need to be strategically deployed to create a stronger market presence. Financial performance should be appropriately communicated to instill confidence and loyalty in customers.

Originality/value

This is the first of such research conducted in Saudi Arabia. Customers' interpretation and perception of corporate image in the Saudi banking industry suggests that corporate branding is as important as corporate identity. As such, this paper reveals that complacency in corporate communication practices is the very reason why market presence fails to endure the test of time.

Abstract

Purpose

The purpose of this paper is to investigate the driving forces (economics and socio-demographic) that influence family Takaful demand in the Middle East and North Africa (MENA) region, using a sample of 15 countries from the MENA.

Design/methodology/approach

The authors use multivariate analysis, bootstrapping and generalised method of moments techniques. They first examine a full model that combines all variables; second, a model that controls for product market factors; and finally, a model that controls for socio-demographic factors. They further separate all models into linear and log-linear demand functions.

Findings

The authors demonstrate that the relationship between the demand for family Takaful in MENA and Islamic banking deposits, education, dependency rate, female life expectancy and Muslim population is significantly positive. On the other hand, the significant factors that are inversely related to the demand for family Takaful in MENA are inflation, financial development and male life expectancy.

Research limitation/implications

The crucial limitation of this study is the amount of data available in regards to the dependent variable, family Takaful contributions. Consequently, to improve the understanding in explaining the family Takaful demand in MENA, further research can take advantage of expanding the variables that were omitted in this research as a consequence of the unavailability of data. Some of the possible influential variables can include government social security expenditure, legal system and government policies, price of Takaful and level of competition within the Takaful and insurance industry.

Originality/value

It is obvious that there are very few studies that focus on the MENA market, and indeed, none of them gives attention to the factors that influence demand for family Takaful. While this study is expected to provide more understanding and awareness on the concept of Takaful and the factors that influence its demand, the authors hope that it would encourage more studies on various issues on the Takaful industry so as to help researchers to understand more aspects of this new emerging business.
