Abstract
Purpose
The aggressive competition in the real estate market forces real estate developers to tackle the challenge of selecting the best project construction phasing alternative. The real estate industry is characterized by high costs, high profit and high risks. The schedules of real estate projects are also characterized by having large number of repetitive activities that are executed over a long duration. The repetitiveness, long duration of execution, the high amounts of money involved and the high risk made it desirable to leverage the impact of changes in phasing plans on net present value of amounts incurred and received over the long execution and selling duration. This also changes the project progress, and delivery time as well as their respective impact on customer degree of satisfaction. This research addresses the problem of selecting the best phasing alternative for real estate development projects while maximizing customer satisfaction and project profit.
Design/methodology/approach
The research proposes a model that generates all construction phasing alternatives and performs decision-making to rank all possible phasing alternatives. The proposed model consists of five modules: (1) Phasing Sequencing module, (2) Customer Satisfaction module, (3) Cash-In calculation module, (4) Cost Estimation module and (5) Decision-making module. A case study was presented to demonstrate the practicality of the model.
Findings
The proposed model satisfies the real estate market's need for proper construction phasing plans evaluation and selection against the project's main success criteria, customer satisfaction and project profit. The proposed model generates all construction phasing alternatives and performs multi-criteria decision making to rank all possible phasing alternatives. It quantifies the score of the two previously mentioned criteria and ranks all solutions according to their overall score.
Research limitations/implications
The research proposes a model that assist real estate market's need for proper construction phasing plans evaluation and selection against the project's main success criteria, customer satisfaction and project profit. The proposed model can be used to conclude general guidelines and common successful practices to be used by real estate developers when deciding the construction phasing plan. In this study the model is based on business models where all the project units are sold, rental cases are not considered. Also, the budget limitations that might exist when phasing is not considered in the model computations.
Originality/value
The model can be used as a complete platform that can hold all real estate project data, process revenues and cost information for estimating profit, plotting cash flow profiles, quantifying the degree of customer satisfaction attributable to each phasing alternative and providing recommendation showing the best one. The model can be used to conclude general guidelines and common successful practices to be used by real estate developers when tackling the challenge of selecting construction phasing plans.

Abstract
Purpose
The sustainable development of contractor organizations depends highly on bidding decision-making of projects. This current study, leveraging the risk decision-making theory, attempts to elucidate the process of contractors’ bid/no-bid decision-making and reveal how the process is influenced by their perception of risk. In particular, this study aims to explore the multiple mediating effects of contractors’ trust in owners and risk perception in explaining the relationship between contractual governance outlined in owners’ bidding documents and the bid/no-bid decisions.
Design/methodology/approach
A questionnaire survey was used to obtain data from the Chinese construction industry. The PLS-SEM technique was employed to analyze a dataset of 557 available questionnaires.
Findings
The findings indicate that (1) the contractual governance provided by owners’ bidding documents positively impacts contractors’ bid/no-bid decisions; (2) both risk perception and trust serve as multiple mediators in this relationship and (3) trust mediates the relationship between contractual governance and contractors’ risk perception.
Originality/value
Drawing upon the risk decision-making theory, this study proposes a multiple mediation model for understanding contractors’ bid/no-bid decision-making processes. It contributes to a better understanding of contractors’ bidding decision-making mechanisms, thereby offering theoretical guidance for contractors to make reasonable and informed risk decisions.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Practical implications
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.
Originality/value
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.

Abstract
Purpose
Despite the importance of emotional variables in shaping individuals' consumption behavior, nature-love still needs to be addressed concerning various aspects of sustainable consumption behavior (SCB). Considering the dimensions of nature-love, this study aims to investigate the effect of passion-for-nature, intimacy-with-nature and commitment-to-nature on SCB. Furthermore, this study aims to incorporate the construal levels of psychological distance (PD) as a moderating variable between the tested variables to add a more in-depth understanding.
Design/methodology/approach
Data was collected from a sample of 311 individuals from Egypt using the snowball sampling method and the ten-time rule technique. The data was analyzed using partial least squares-structural equation modeling (PLS-SEM).
Findings
The findings indicate that passion-for-nature and intimacy-with-nature have a significant positive effect on green purchasing, reusability and recycling. On the other hand, commitment-to-nature has a significant positive effect on both green purchasing and reusability. Additionally, a high PD acts as a moderator between the relationships tested. The findings have been discussed in terms of their theoretical and practical implications.
Originality/value
To the best of the authors’ knowledge, this is the first study to integrate PD as a moderator between the relationships tested. Additionally, this paper is the first empirical research investigating these relationships in developing economies.

Abstract
Purpose
This study aims to explore how the structure of the board of directors is influenced by national informal culture values and the strength of formal institutional environments, as measured through legal regulations, market conditions and investor protection regulations.
Design/methodology/approach
This study analyzes data from 432 companies listed in the S&P Global 1200 index using structural equation modeling. National cultural dimensions from Hofstede’s (2011) framework capture informal cultural aspects, while the World Bank’s Worldwide Governance Indicators assess formal institutions. This study examines board structure in terms of leadership style, board size, board independence, board committee structure and board diversity.
Findings
The results reveal that national cultural values are negatively associated with rule of law institutions, indicating that culture can substitute for legal institutions, acting as “soft” regulation. Cultural values establish social norms and accountability when legal frameworks are weak. In addition, national culture positively relates to open market institutions, enhancing transparency, fairness and competition in strong markets. The findings also show that national culture and formal institutions significantly shape managerial perceptions of the board’s role and structure, impacting how firms prioritize monitoring versus resource provision.
Research limitations/implications
The findings offer valuable insights for managers in diverse institutional contexts, enabling them to adjust board structures according to cultural and institutional factors.
Practical implications
The research advocates for tailored governance practices that fit specific institutional and cultural contexts. Multinational corporations can benefit from customizing their governance structures according to the cultural and institutional environments of the countries in which they operate.
Originality/value
This paper contributes to existing literature by focusing on complementarity as well as substitution mechanisms between national cultural characteristics and formal institutions in shaping board structure.

Abstract
Purpose
This study aims to explore the status and drivers (including free-floated shares, board size, rule duality and board independence) of corporate risk disclosure (CRD) for the conventional listed banks in the Egyptian stock market from 2010 to 2021, which include the country’s major political upheavals and the COVID-19 pandemic.
Design/methodology/approach
This study based on a sample of 117 annual reports of sampled banks from 2010 to 2021. RD index of Al-Maghzom (2016) was developed and adopted to quantify CRD using an unweighted scoring system. The multiple linear regression model was used to validate the hypotheses.
Findings
The analysis shows that the COVID-19 pandemic increased insignificantly disclosure of all risks except for segment risks. In addition, findings reveal that all sampled banks adhere highly to the requirements of mandatory RD, with a low level of adherence to voluntary RD. Moreover, the analysis concluded that the board size and free-floating shares positively affect the disclosure of financial, operational, general information.
Research limitations/implications
The study’s limitations include the content analysis methodology, reliance on annual reports, emphasis on financial and non-financial risks, focus on listed conventional banks in Egypt.
Practical implications
Current study’s findings are more likely to be useful for many parties. It informs investors about the characteristics of the boards’ directors of Egyptian listed banks that disclosed risk information. Banks should disclose more comprehensive risk information. For academics, the current study’s limitations can be considered in their future research.
Originality/value
This work fills a new research area in which there is relatively little research in emerging financial markets that adds new evidence to the relationship between RD and both free-floating shares and board characteristics, particularly in Egypt.

Abstract
Purpose
This study aims to examine the performance indicators (PIs) for assessing environmental management plan (EMP) implementation in road construction projects. The specific objectives are to compare the key PIs between environment auditors and environment officers and among project stakeholders, develop components to categorize interrelated key PIs and evaluate the effectiveness of interrelated key PIs and components.
Design/methodology/approach
Thirty-nine PIs were identified through a systematic literature review and in-depth interviews with environmental professionals. Subsequently, a questionnaire survey was designed based on this list of PIs and distributed to industry professionals. Sixty-one responses were collected in Malaysia and analyzed using the mean score ranking, normalization, agreement analysis, overlap analysis, factor analysis and fuzzy synthetic evaluation.
Findings
The analyses identified 18 key PIs: soil erosion, dust appearance, spill of chemical substance, construction waste, clogged drainage, overflowed silt trap, oil/fuel spills, changes in the colour of bodies of water, excessive cut and fill, vegetation depletion, changes in the colour of the runoff water, landslide occurrence, slope failures, irregular flood, public safety, deforestation, open burning and increased of schedule waste. Also, the key PIs can be grouped and ranked into the following four components: geological, pollution, environmental changes and ecological. Finally, the overall importance of the key PIs is between important and very important.
Originality/value
This study is a pioneer in quantitively examining the key PIs for EMP implementation in road construction projects. Researchers, industry practitioners and policymakers can use the findings to develop strategies and tools to allow public monitoring of EMP implementation.
