Abstract
Purpose
Support at the organizational and managerial levels defines the degree to which construction workplaces can accommodate disabled and injured workers. There is little empirical evidence about the indicators and practices that can be used by construction organizations to evaluate disability management (DM). This paper aims to develop and validate key indicators and practices of disability/injury management within construction.
Design/methodology/approach
To achieve this, the research used a two-phase sequential exploratory review of literature, followed by a quantitative phase, using analytic hierarchy process. The analytical hierarchy process (AHP) involved recruiting eight health and safety and DM experts to conduct pairwise comparisons of these indicators.
Findings
The results found return-to-work and disability and injury management practices to be the most important indicators and physical accessibility and claims management practices to be the least important.
Practical implications
The development of these indicators should help construction organizations develop DM programs that better meet their needs, and benchmark and improve related performance.
Social implications
The results could also be useful for all stakeholders in general and decision makers in particular involved within construction.
Originality/value
Such prioritization helps organizations to prioritize their DM practices thereby optimizing performance.

Abstract
Purpose
A review of the literature revealed a lack of coherent frameworks for implementing disability management, particularly within the construction industry. This study involved developing the construction disability management maturity model (CDM3) to assess the maturity of disability management (DM) practices in construction organisations.
Design/methodology/approach
In its current form, the model assessed twelve indicators using a series of questions representing relevant best practices for each indicator and five different maturity levels. An analytical hierarchical process was conducted using eight construction and DM experts to determine the weights of importance of these different indicators. The model was then applied to evaluate ten construction companies in Manitoba, Canada.
Findings
The results revealed that the indicators of “Return to Work”, “Disability and Injury Prevention”, and “Senior Management Support” practises were the most heavily weighted and, thus, the most important. Companies' DM performance was observed, on average, to be at the quantitatively managed level. “Senior Management Support” and “Disability Injury Prevention” practices were observed to be the most mature indicators on average, revealing a potential relationship between the most important and most mature indicators.
Research limitations/implications
The sample size of companies evaluated is a key limitation in that it does not permit for the generalisation of the results.
Practical implications
This study provided a framework for benchmarking the DM performance of construction organisations.
Originality/value
No similar maturity model has been developed to date to assess DM in construction, making the CDM3 the first of its kind to evaluate a construction organisation's existing DM practices against best practises.

To examine the perspective of third-level university students in the context of the value proposition of construction apprenticeships in Ireland.
Abstract
Purpose
To examine the perspective of third-level university students in the context of the value proposition of construction apprenticeships in Ireland.
Design/methodology/approach
The research uses a qualitative method, conducting semi-structured interviews with 20 third-level university students enrolled on a Bachelor of Science (Honours) degree program in Construction Management in Ireland.
Findings
The results highlight six themes. These include that society appears to be directly and/or indirectly steering students towards university. This is driven by what appears to be a prevailing stigma in that apprenticeships are not seen as an achievement by society. Also, apprenticeships are seen as a limited career choice, while also being one which appears to repel female entrants.
Practical implications
If the shortage of new skilled workers entering the construction industry continues, construction organisations will not have the necessary resources to tender for, and subsequently, complete new work.
Social implications
The perception of what could have been seen as potential new apprenticeship entrants, but ultimately chose university, is worth examining further with a view to industry addressing the shortcomings identified. This therefore can provide an opportunity to stem the tide of reducing apprenticeship numbers, while also providing a viable alternative to university for those who wish to pursue alternative routes of entering the sector.
Originality/value
The paper uniquely focuses on the third-level university student's perspectives and what influenced their decision to pursue third-level university education over that of an apprenticeship within the built environment; an area which has yet to be investigated.

Abstract
Purpose
This paper provides a theoretical foundation and conceptual framework to explain the interactions among risk management (RM), top management support (TMS), and internal audit activities (IAA) to achieve internal control quality (ICQ).
Design/methodology/approach
A review of the extant literature in RM, auditing and management control is conducted to develop and establish theoretical relationships.
Findings
In this work, interconnectedness among organisational factors is discussed by drawing on contingency theory to provide the theoretical logic and support the conceptual framework.
Research limitations/implications
Although this work illustrates the significance of the moderation effect of TMS and the mediation effect of IAA to link RM processes with the quality of internal controls, limitations exist, as the study is conceptual and lacks empirical evidence. The paper emphasises education and training on RM and internal audit to address emerging issues and arising challenges in RM and ICQ.
Originality/value
The paper extends the existing literature in the area of ICQ, which is discussed extensively in developed contexts. However, studies on ICQ in emerging economics, specifically the Middle East and North Africa region, which suffers from high levels of corruption, and asset misappropriation cases are limited. Hence, this work is important because it addresses under-researched issues in relation to ICQ in an attempt to develop a conceptual framework from the available and most effective organisational factors to attain better ICQ.

Abstract
Purpose
The purpose of this study is to examine the impact of firm financial and operational characteristics on the level of forward-looking information disclosure (FLID) by Egyptian-listed non-financial companies. The present research also aims to investigate the moderating role of gender diversity on the board of directors.
Design/methodology/approach
The sample incorporates the non-financial companies included in the EGX 100 of the Egyptian Stock Exchange (ESE), whose reports were available during the study period from 2013 to 2018. The final sample comprises 49 companies with 294 observations. Statistical analysis is performed using multiple regression analysis.
Findings
This study found a significant positive impact of return on assets, leverage, company size and age on the level FLID, while external audit firm type and industry were found to impact the level of FLID negatively. Further, the board gender diversity (BGD) is found to have a moderating impact as it strengthens the effect of financial and operational characteristics on the level of FLID.
Practical implications
The present study has some implications for Egyptian companies, investors in the Egyptian market and regulators in emerging economies, which include paying more attention to BGD when selecting the board members by companies as well as following up the female representation in all the listed companies by regulators.
Originality/value
To the best of the authors’ knowledge, this is the first study to investigate the moderating role of BGD and its impact on the level of FLID in emerging markets. This extends the disclosure literature as the present study brings new evidence from an emerging market regarding BGD moderating role as early research concentrated on the direct impact of BGD on the level of FLID.

Abstract
Purpose
A majority of higher education institutions (HEIs) in Oman, and internationally, have adopted English as the language of education, driven by its power and its globally accepted status as the language of knowledge and communication. Such an internationalisation policy has been inadequately evaluated to examine its actual effects. This paper aims at analysing the existing literature with a view to hypothesise the effects of adopting English as a medium of instruction (EMI) on establishing intellectual capital in the Omani context.
Design/methodology/approach
The paper employs a case study design that draws on data generated through a systematic review of 94 peer-reviewed papers that are synthesised using thematic analysis.
Findings
The findings indicate that EMI negatively affects the optimal creation of intellectual capital through limiting access to HE, hindering knowledge transfer, impeding Omanis' employability and hindering faculty's professional growth. EMI leads HEIs to mirror the supplying countries' cultures in terms of materials, ideologies and standards. It affects teaching and research quality, training and communication, the sense of equity, belonging and self-worth amongst students and the relationships amongst faculty members. It also increases reliance on external stakeholders.
Research limitations/implications
The paper highlights the interconnection between the forms of intellectual capital and how some components are antecedents to the creation of the intellectual capital forms. It establishes the moderating role the language of instruction plays in relation to the three sub forms of intellectual capital in higher education.
Practical implications
The paper calls for maximising higher education intellectual capital through adopting bilingual rather than monolingual higher education. It calls upon policymakers to revisit the assumptions underlying higher education systems in order to optimise their outcomes.
Originality/value
The paper is the first one that sheds light on the role of language in intellectual capital construction. Such a moderating role has received almost no attention in the higher education literature that is largely busy quantifying its outcomes rather than ensuring they are actually sustainably generated.

Abstract
Purpose
In the present work, under severe conditions of an inert atmosphere and high temperature, epoxidized natural rubber (ENR) with 25 per cent epoxidation level reacts with different aliphatic amine compounds such as ethyl amine (EA), propyl amine (PA) and butyl amine (BA) to prepare ENR/EA, ENR/PA, ENR/BA compounds as, respectively. The produced compounds were characterized by Fourier transform infrared spectroscopy and oxirane oxygen content determination. Different concentrations of the produced compounds were added to epoxy and urethane acrylate coating formulations to evaluate them as corrosion inhibitors for mild steel under UV irradiation. Corrosion resistance tests and weight loss measurements of the coated steel panels were made. It was found that coating formulations containing the prepared ENR/EA compound could protect metal surface from corrosion, and corrosion inhibitors efficiency of the prepared compounds were arranged as follows: ENR/EA > ENR/PA > ENR/BA. The optimum concentrations for all inhibitors which give the best inhibition efficiency for corrosion are 0.4-0.6 phr.
Design/methodology/approach
Corrosion scratch tests were carried out according to ASTM D 1,654-92 (2000). The weight loss of coated steel was measured according to ASTM D 2,688-94 (1999). The measurement of film hardness was carried out with a Wolff–Wilborn pencil hardness tester according to ASTM D 3,363 (2000).
Findings
It was found that coating formulations containing the prepared ENR/EA compound could protect metal surface from corrosion and corrosion inhibitors efficiency of the prepared compounds were arranged as follows: ENR/EA > ENR/PA > ENR/BA. The optimum concentrations for all inhibitors are 0.4-0.6 g/100g coating.
Originality/value
A highly efficient and economically corrosion inhibitors for mild steel were prepared from ENR and series of aliphatic amines.

This study aims to analyze the impact of corporate governance on firms’ external financing decisions in the Middle East and North Africa (MENA) region.
Abstract
Purpose
This study aims to analyze the impact of corporate governance on firms’ external financing decisions in the Middle East and North Africa (MENA) region.
Design/methodology/approach
The authors analyzed a unique set of panel data comprising 2,425 nonfinancial firms whose shares are traded on stock exchanges in countries in the MENA region. The authors fitted an ordinary least squares model to estimate the regression coefficients. The authors performed a sensitivity analysis using alternative measures of the critical variables and an endogeneity analysis using instrumental variable methods with plausible external instruments.
Findings
The results revealed that corporate governance characteristics of firms are strongly associated with their degree of leverage. They also showed that macrofinancial conditions, financial regulations, corporate governance enforcement and social conditions mitigate the impact of corporate governance on firms’ financing decisions.
Research limitations/implications
A larger sample size will further improve the results; however, this is difficult and depends on the extent to which increasing disclosure practices allow more corporate information to reach international databases.
Practical implications
This study provides new evidence on the role of corporate governance on firms’ financing decisions and documents the essential mitigating role of institutions, alerting managers to consider them.
Originality/value
This study is a novel attempt. Based on information from different data sources, this study explored the predictive power of corporate governance, ownership structures and other firm-specific characteristics in explaining corporate leverage in MENA countries. Overall, the analysis provides new evidence of the association between corporate governance and capital structure in the MENA region, highlighting the critical role of institutions.

Abstract
Purpose
The purpose of the paper is to present an integrated model for the location of warehouse, the allocation of retailers to warehouses, and finding the number of vehicles to deliver the demand and the required vehicle routing in order to minimize total transportation costs, fixed and operating costs, and routing costs.
Design/methodology/approach
The model assumes that the number of plants has already been determined and answers the following questions: what is the number of warehouses to open? How warehouse are allocated to plants? How retailers are allocated to warehouses? Who are the retailers that will be visited and in what order? How many vehicles are required for each route? What are the total minimum costs?
Findings
The model was formulated as a mixed integer linear programming model and solved using Lagrange relaxation and sub‐gradient search for the location/allocation module and a traveling salesman heuristic for the routing module. The results for the randomly selected problems show that the deviation in objective function value ranges between 0.29 and 2.05 percent from the optimum value. Also, from the CPU time point of view, the performance was very good.
Originality/value
An attempt is made to integrate location, allocation, and routing decisions in the design of a supply chain network.

This study aims to evaluate the efficiency of using some polymers at different concentrations in the consolidation of vegetable-tanned leather artifacts.
Abstract
Purpose
This study aims to evaluate the efficiency of using some polymers at different concentrations in the consolidation of vegetable-tanned leather artifacts.
Design/methodology/approach
New vegetable-tanned leather samples were prepared. The consolidants used were polyacrylamide (PAM) and polymethyl methacrylate/hydroxyethyl methacrylate (MMA-HEMA). Accelerated heat aging was applied to the untreated and treated samples. Analytical techniques used were Fourier transform infrared spectroscopy (FTIR), digital microscope, scanning electron microscope (SEM), change of color and mechanical properties.
Findings
The characteristic FTIR bands showed the effect of accelerated heat aging on the molecular structure of the studied samples, but treated and aged treated samples used were better than aged untreated samples. Microscopic investigations (digital and SEM), and mechanical properties proved that 2% was the best concentration for polymers used. The change in the total color difference of the treated and aged treated samples was limited.
Originality/value
This study presents the important results obtained from PAM and poly(MMA-HEMA) used for the consolidation of vegetable-tanned leather artifacts. The best results of the studied polymers can be applied directly to protect historical vegetable-tanned leathers.
