The Middle East and North Africa (MENA) region is known for its extreme weather conditions during Summer. A major determinant of the sustainability of the design of a building is its fenestrations. The purpose of this paper is to explore the problem of designing and locating windows on building facades such that a number of relevant criteria to the MENA region are optimised, including solar heat gain, privacy, daylighting and cost of installation.

A multi-objective optimisation problem is proposed with the focus on capturing the requirements of residential dwellings in the MENA region. Since the problem contains conflicting objectives that need to be optimised, a lexicographic approach is adopted. In order to display the Pareto curve, a bi-objective analysis based on the ε-constraint method is utilised.

The conflicting nature of the proposed problem is indicated via the Pareto optimal solutions yielded. Depending on the preference of criteria adopted in lexicographic optimisation, the location of the windows on the building façade tends to change. The bi-objective analysis indicates the importance of balancing out the daylight factor against each of privacy, solar heat gain and installation cost criteria. Furthermore, an analysis conducted in three major cities in the MENA region highlights the discrepancy in design alternatives generated depending on the local climatic condition.

This work proposes a novel mathematical optimisation model which focuses on producing a sustainable design and layout for windows on the facades of residential dwellings located in the MENA region. The proposed model provides designers with guidance through an automated support tool that yields optimised window designs and layout to ensure the sustainability of their designed buildings.

This paper aims to introduce an innovative decision-making framework designed to optimize egress location selection in buildings, significantly enhancing safety during emergencies. By integrating social, economic and technical criteria through the fuzzy analytic hierarchy process (F-AHP), this framework effectively manages the uncertainties inherent in emergency scenarios, providing a robust tool for safeguarding lives and property.

The proposed methodology employs the F-AHP to systematically integrate and evaluate social, economic and technical criteria for egress location selection. A comprehensive case study conducted on a one-story school building demonstrates this approach’s practical application and effectiveness.

The analysis reveals that economic criteria are the most significant in determining the optimal egress location, constituting 61.9% of the overall weight, followed by technical criteria at 26.8% and social criteria at 11.3%. The findings highlight the practical application and effectiveness of the proposed approach in addressing uncertainties and optimizing egress location selection. Integrating social, economic and technical considerations gives decision-makers a robust tool to optimize safety, cost-effectiveness and evacuation efficiency.

The findings underscore the practical benefits and effectiveness of the proposed approach in managing uncertainties and improving the selection of optimal egress locations. Integrating social, economic and technical considerations gives decision-makers a robust tool to optimize safety, cost-effectiveness and evacuation efficiency. This approach equips practitioners with a comprehensive framework for enhancing emergency preparedness and resilience in various building scenarios.

This research introduces a novel framework for egress location selection that addresses the limitations of existing studies by integrating multiple criteria – social, economic and technical – into a cohesive decision-making process. Using the F-AHP in a case study illustrates the framework’s practicality and adaptability, providing a dynamic solution that enhances the overall effectiveness of emergency plans. By prioritizing safety, cost-effectiveness and efficiency, this framework ensures that emergency plans are robust and adaptable, thereby significantly enhancing resilience in the face of emergencies.

The purpose of this paper is to use Bourdieu’s Theory of Capital–Field–Habitus to explore how refugees, asylum seekers and migrants accumulate and mobilise social, cultural, symbolic and economic capital to find meaningful work in the Australian construction industry.

The paper reports the results of a survey of refugees, asylum seekers and migrants who have either successfully or unsuccessfully searched for employment in the Australian construction industry.

The findings dispel widely held negative stereotypes of about this group by describing a highly capable workforce which could address significant skills shortages in the industry, while concurrently diversifying the workforce. However, it is found that refugees, asylum seekers and migrants face considerable barriers to finding meaningful employment in the construction industry. In circumventing these barriers, education institutions, charities and community-based organisations play an especially important role, alongside friends and family networks. They do this by helping refugees, asylum seekers and migrants accumulate and deploy the necessary capital to secure meaningful work in the construction industry. Disappointingly, it is also found that the construction industry does little to help facilitate capital accumulation and deployment for this group, despite the urgent need to address diversity and critical skills shortages.

Employing Pierre Bourdieu’s Theory of Capital–Field–Habitus, the findings make a number of new theoretical and practical contributions to the limited body of international research relating to the employment of refugees, asylum seekers and migrant workers in the construction. The results are important because meaningful employment is widely accepted to be the single most factor in the successful integration of refugees, asylum seekers and migrants into a host society and the construction industry represents an important source of potential employment for them.

Research investigating the impact of school leadership on teachers’ emotions and practices has mostly focused on the leadership behaviors of school principals, thus ignoring the potential leadership qualities of other school members, especially teachers. The current study aimed to bridge this gap by providing further insight into the link between teacher leadership and teacher outcomes in Egyptian schools. Specifically, the study examined the mediating role of collective teacher efficacy in the relationship between teacher leadership and teacher commitment.

The study employed structural equation modeling and bootstrapping to analyze survey data collected from 497 teachers in primary and middle schools in Damietta city, Egypt.

The results supported our proposition that teachers’ leadership practices have more indirect than direct effects on teacher commitment through collective teacher efficacy. That is, teacher leadership practices positively affect teachers’ efficacy beliefs, which, in turn, increase their sense of commitment to school.

The study adds a new aspect to the literature by investigating the potential role of teacher leadership in promoting positive teacher attitudes that can have a positive impact on student learning. This is significant given the growing emphasis that educational systems place on enhancing school effectiveness. Specifically, understanding the factors that contribute to teacher commitment can inform strategies for retaining effective teachers and improving the overall quality of the teaching workforce. Additionally, since most of the empirical research on teacher leadership has been produced in Western contexts, it is important to enrich the field with studies conducted in other societies, especially in the Arab region.

The alternative medical practices of both Ottoman and Andalusian heritages could be shown through bloodletting and cupping therapies that have been utilized in various ancient civilizations. The current study endeavors to explore the historical implementation of bloodletting as a sustainable medical heritage by Muslim physicians in the Andalusian and Ottoman empires as a part of their surgical heritage that is documented in their manuscripts and miniatures.

The primary research materials utilized in this case study are the copy of the manuscript Al-Tasrif li-man ‘Ajiza ‘an al-Taʾlif in Berlin library and the copy of the manuscript Cerrahiye-I Ilhaniye of the National Library in Paris. The study applies an analytical comparative approach to examine the practice of bloodletting by two Muslim physicians as a part of reviving heritage usage.

The present study investigates the heritage in both periods throughout implementation of cupping therapy by Al-Zahrawi and Sabuncuoglu, while also examining the resemblances and divergences in the techniques of bloodletting as a heritage medical treatment employed by these Muslim physicians and still used in Muslim culture and could be used in medical tourism purposes.

The current study aims to investigate the understanding and implementation of heritage bloodletting and cupping therapy as a sustainable tool in surgical purposes, through an exploration of treatment methods detailed in both manuscripts. Additionally, it examines the contributions made by the two surgeons toward the development of new cups and the refinement of processes involved in bloodletting and cupping therapy. Furthermore, the study highlights the locations where cupping can be performed and differentiates between dry and wet cupping techniques, as depicted in the painted instruments documented in both manuscripts.

Existing labor estimation models typically consider only certain construction project types or specific influencing factors. These models are focused on quantifying the total labor hours required, while the utilization rate of the labor during the project is not usually accounted for. This study aims to develop a novel machine learning model to predict the time series of labor resource utilization rate at the work package level.

More than 250 construction work packages collected over a two-year period are used to identify the main contributing factors affecting labor resource requirements. Also, a novel machine learning algorithm – Recurrent Neural Network (RNN) – is adopted to develop a forecasting model that can predict the utilization of labor resources over time.

This paper presents a robust machine learning approach for predicting labor resources’ utilization rates in construction projects based on the identified contributing factors. The machine learning approach is found to result in a reliable time series forecasting model that uses the RNN algorithm. The proposed model indicates the capability of machine learning algorithms in facilitating the traditional challenges in construction industry.

The findings point to the suitability of state-of-the-art machine learning techniques for developing predictive models to forecast the utilization rate of labor resources in construction projects, as well as for supporting project managers by providing forecasting tool for labor estimations at the work package level before detailed activity schedules have been generated. Accordingly, the proposed approach facilitates resource allocation and enables prioritization of available resources to enhance the overall performance of projects.

The bid/no-bid decision is critical to the success of construction contractors. The factors affecting the bid/no-bid decision are either qualitative or quantitative. Previous studies on modeling the bidding decision have not extensively focused on distinguishing qualitative and quantitative factors. Thus, the purpose of this paper is to improve the bidding decision in construction projects by developing tools that consider both qualitative and quantitative factors affecting the bidding decision.

This study proposes a mixed qualitative-quantitative approach to deal with both qualitative and quantitative factors. The mixed qualitative-quantitative approach is developed by combining a rule-based expert system and fuzzy-based expert system. The rule-based expert system is used to evaluate the project based on qualitative factors and the fuzzy expert system is used to evaluate the project based on the quantitative factors in order to reach the comprehensive bid/no-bid decision.

Three real bidding projects are used to investigate the applicability and functionality of the proposed mixed approach and are tested with experts of a construction company in Alberta, Canada. The results demonstrate that the mixed approach provides a more reliable, accurate and practical tool that can assist decision-makers involved in the bid/no-bid decision.

This study contributes theoretically to the body of knowledge by (1) proposing a novel approach capable of modeling all types of factors (either qualitative or quantitative) affecting the bidding decision, and (2) providing means to acquire, store and reuse expert knowledge. Practical contribution of this paper is to provide decision-makers with a comprehensive model that mimics the decision-making process and stores experts' knowledge in the form of rules. Therefore, the model reduces the administrative burden on the decision-makers, saves time and effort and reduces bias and human errors during the bidding process.

The purpose of this paper is to present a model for building information modelling (BIM) implementation at small and medium-sized construction contractor organisations (SMOs). The proposed BIM adoption model assesses BIM implementation benefits, costs and challenges faced by SMOs. Correlation between BIM adoption in SMOs and the associated impacting factors, including knowledge support and BIM adoption motivation, is captured through the model.

A literature review of BIM adoption in construction was first presented. Research data, collected from 80 SMOs in Australia through a conducted survey, are then analysed. Descriptive analysis and structural equation modelling were used to investigate SMOs’ understanding of BIM, and to qualify the correlations among the proposed latent variables impacting BIM implementation at SMOs, respectively. Additionally, this study used χ² test to compare differences between BIM users and non-BIM users regarding BIM understanding, interested applications and attitudes towards implementation benefits and challenges.

Potential benefits associated with BIM implementation are a major motivation factor when it comes to BIM adoption at SMOs. In addition, existing staff’s capability in using BIM tools positively affects the establishment of an organisational knowledge-support system, which determines the decision of adopting BIM eventually. Ultimately, there is a need for further emphasis on staff engagement in the implementation process.

The results presented in this paper are applicable to SMOs in the building sector of construction. BIM implementation at organisations involved in non-building activities, including civil works and infrastructure, needs to be assessed in the future.

The results indicate that rather than placing the focus mainly on benefits of BIM implementation, successful implementation of BIM in practice requires adequate effort to assess implementation problems, establish knowledge support and engage staff in using BIM.

Results of this study provide an insight into the adoption challenges of BIM in SMOs, given that the focus of previous studies has been mostly placed on BIM adoption in architectural firms and large contractors.

In Australia, as in many other countries, refugees are over-represented in the ranks of the unemployed, under-employed and precariously employed and often become frustrated in their attempts to secure work. Despite the construction industry being a major potential source of employment for refugees, there has been a surprising lack of research into their experiences of securing work in the industry. Addressing this gap and also the general lack of voice for refugees in construction research, the aim of this paper is to explore the barriers refugees face in securing employment in the construction industry.

This paper reports a survey of refugees who have worked or attempted to seek work in the Australian construction industry.

Results show that the main barriers to securing employment in construction are: lack of local work experience; employer discrimination; employer failure to recognise previous qualifications, skills and experience and employers not understanding the challenges they face. Government employment agencies and systems are also perceived to be of limited value and overly complex, in contrast to the activities of not-for-profit support agencies.

While the research is limited to Australia, the findings contribute an important and missing refugee dimension to the emerging body of research on construction social procurement. They also contribute unique sector-specific insights into the broader debate about refugee resettlement and employment. Further research is needed in other national contexts.

Recommendations are made to address the barriers to employment identified including: initiatives to provide refugees with work experience in the industry; education to break-down negative stereotypes of refugees among employers; greater support for not-for-profits supporting refugees and reform of government and employment agency systems and procedures.

By enhancing understanding of the barriers to employment for refugees in construction and proposing solutions to reduce those barriers, this research contributes new insights into a growing global challenge of how we better integrate growing numbers of refugees into harmonious and prosperous societies.

The findings are important in facilitating the smoother integration of refugees into society. Beyond the moral imperative, there are significant social, cultural and economic benefits which successful refugee integration brings to host countries and industries like construction which in many countries are now being required to employ refugees in their workforce as a condition of public sector contracts.
