The purpose of this study is to investigate the potential of using computer vision and deep learning (DL) techniques for improving safety on construction sites. It provides an overview of the current state of research in the field of construction site safety (CSS) management using these technologies. Specifically, the study focuses on identifying hazards and monitoring the usage of personal protective equipment (PPE) on construction sites. The findings highlight the potential of computer vision and DL to enhance safety management in the construction industry.

The study involves a scientometric analysis of the current direction for using computer vision and DL for CSS management. The analysis reviews relevant studies, their methods, results and limitations, providing insights into the state of research in this area.

The study finds that computer vision and DL techniques can be effective for enhancing safety management in the construction industry. The potential of these technologies is specifically highlighted for identifying hazards and monitoring PPE usage on construction sites. The findings suggest that the use of these technologies can significantly reduce accidents and injuries on construction sites.

This study provides valuable insights into the potential of computer vision and DL techniques for improving safety management in the construction industry. The findings can help construction companies adopt innovative technologies to reduce the number of accidents and injuries on construction sites. The study also identifies areas for future research in this field, highlighting the need for further investigation into the use of these technologies for CSS management.

This research investigates the financial viability risk factors that threaten the private investor's economic scheme in the public private partnership (PPP) wastewater treatment plant (WWTP) projects in Egypt. The aims of this study are to: (1) illustrate and cluster the financial viability risk factors in accordance with the PPP WWTP projects' nature, (2) assess the risk factors' criticality degrees according to their severity and frequency levels of the financial viability, and (3) pinpoint the suited allocation of the financial viability risk factors between the public and private parties.

Relying on the previous analysts' endeavors, the questionnaire method, the fuzzy synthetic evaluation approach and the hypothetical normal distribution curve model; the severity, frequency, criticality and allocation preference of 32 financial viability risk factors were assessed from 12 Egyptian PPP experts.

The data analysis yielded that foreign exchange risk, currency risk/inflation, license risk, construction cost-overrun and late site handover are the key factors in arising the financial viability risk issue in the PPP WWTP projects. Considering the discussion of these key risks, the study summarized that the financial viability's key risk factors are notably be affected by the economic, political and administrative circumstances of the host county. Additionally, the inflation lesion was found to be the core reason of most of the key risk factors.

This research originality stems from its contribution to address the gab in the PPP risk assessment literature of the concessionaire's financial viability in the WWTP projects in a country of developing economy as Egypt. This, first, enriches the scholarly based knowledge of the PPP projects' risk analysts of the developing countries. Accordingly, it moves the current PPP risk assessment research further to deeply apprehend these markets' risks. Second, it equips the policymakers in the public and private sectors of such projects with a map that clarifies their assigned risk factors and the responsibilities that each party should bear to generate a mutual stable investment environment for achieving their aims successfully. This, indeed, paves the way for more private investments to be involved in the developing markets' PPP projects with a profitable satisfactory level for the private concessionaire. In the same vein, more WWTP projects, which are highly needed for the public sector and its people, are executed.

This paper investigates the moderating role of sustainability committees in the relationship between environmental, social and governance (ESG) performance and environmental innovation within European nonfinancial firms.

The study analyzes data from 691 nonfinancial sector firms operating within EU states from 2013 to 2022. It employs regression analysis to examine the correlation between ESG performance and environmental innovation, considering the moderating effect of sustainability committees.

The research reveals a significant and positive correlation between ESG performance and environmental innovation. Moreover, it demonstrates that sustainability committees play a positive moderating role in this relationship, indicating their importance in fostering environmental innovation within organizations.

The study is limited to European nonfinancial companies, potentially limiting the generalizability of findings. Additionally, the research focuses on the moderating role of sustainability committees, leaving room for further exploration of other governance mechanisms.

The findings suggest that implementing an ESG performance framework and establishing dedicated sustainability oversight mechanisms, such as sustainability committees, can enhance environmental innovation within organizations. This insight is valuable for strategic decision-making aimed at advancing both sustainability and innovation agendas.

This study addresses a gap in the literature by exploring the moderating effect of sustainability committees on the link between ESG performance and environmental innovation from various theoretical viewpoints. It contributes to the understanding of mechanisms that enhance environmental innovation within companies and provides practical implications for corporate reporting accuracy and sustainability initiatives.

This study aims to empirically examine the impact of internal corporate governance mechanisms (ICGM) related to the size of the board, board composition, CEO duality and audit committee independence as a single metric on a firm’s investment decisions.

This study attempts to develop an internal corporate governance quality index comprising 10 items under four main ICGMs – size and independence of the board, CEO duality and audit committee independence – employing panel data analysis to investigate its impact on the investment decisions in 301 nonfinancial firms listed in six emerging capital markets in the Gulf Cooperation Council (GCC) member countries for the years 2015–2020. Data were extracted from sample companies' websites, stock markets, annual reports and Refinitiv database.

This study provides convincing evidence that effective ICGMs minimize inefficient investment and ultimately boost investment efficiency. The findings remain consistent even after considering the potential endogeneity bias.

This study provides empirical evidence on investment efficiency in the GCC region and emphasizes the importance of high-quality ICGMs in reducing inefficient investment. By examining the impact of ICGMs on investment inefficiencies, this study contributes to the corporate governance literature. The GCC region's unique economic and social contexts, with its growing economies, are considered to shed light on this issue.

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.

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.

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.

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.
