Waste management remains a pressing issue in the face of climate change and environmental pollution. Recycling shipping containers for reuse can not only reduce environmental pollution but also offer solutions to social issues. The purpose of the study is to analyze and demonstrate how the application of circular eco­ nomy principles and regenerative project management can transform the issue of used shipping containers into a sustainable solution. Using qualitative met­ hods, including literature review and case studies, the authors explore potential uses of recycled shipping containers. The paper examines projects using recycled shipping containers, ranging from mobile kitchens for school meals in El Salvador and affordable student housing in South Korea to commercial solutions in Russia. The study’s findings demonstrate that container reuse can reduce construction pollution, lower the carbon footprint, and provide affordable housing. The study highlights container reuse projects as a sustainable strategy for addressing environmental and social challenges, transforming waste into a valuable resource for local community development.

IPMA CCT certification for consultants, coaches, and trainers in project ma­ nagement, which is part of the certification line of the International Project Management Association (IPMA), has been analyzed. The certification is based on the IPMA ICB4CCT standard requirements. In Russia, this certification is implemented by the National Project Management Association “SOVNET”. The relevance of the research stems from the growing need to ensure the quality of educational and consulting support for project activities. Implementing IPMA CCT certification is a logical response to the challenges associated with the need to confirm the competence of specialists developing project management talent. The study is based on an analysis of IPMA regulatory and methodological documentation (ICB4, ICB4CCT, and ICRCCT), as well as internal materials and practices of the SOVNET’s certification programs. Methods of system analysis, classification, and comparative description have been used. The authors define the CCT certification’s place within the IPMA-SOVNET certification system, describe its three-level structure, and outline key candidate requirements. The competencybased assessment model has been analyzed, and the end-to-end certification process has been described. It has been concluded that the CCT certification implementation in Russia expands opportunities for professional growth for consul­ tants, coaches, and trainers and contributes to improving the quality of training for project management specialists.

The purpose of this study is to analyze the relationships between Project management leadership pattern and performance, innovation work behavior and performance, and receptiveness to innovation and performance. A quantitative research method was employed, and the analysis was conducted using Partial Least Squares–Structural Equation Modeling (PLS-SEM) via Smart PLS software version 4.0.9.9. PLS-SEM was chosen for its suitability in analyzing complex models with multiple constructs and pathways, particularly in exploratory research contexts. The study surveyed 289 Gulf project-based companies, selected through snowball sampling based on the accessibility of reliable participants who had already completed the questionnaire. PLS-SEM is especially effective for handling different sample sizes, non-normal data distributions, and both reflective and formative constructs. It also prioritizes maximizing the explained variance of dependent variables and is well-suited for testing relationships between latent constructs. A five-point Likert scale was used to measure respondents’ agreement with statements related to the variable indicators, ranging from 1 (strongly disagree) to 5 (strongly agree). The data analysis included validity testing, reliability testing, significance testing, and hypothesis testing. The results indicate that Project management leadership pattern has a positive and significant relationship with performance. Similarly, innovation work behavior and receptiveness to innovation both show positive and significant associations with performance.

Cloud computing systems have been identified as an important technology that could increase the competitiveness and effectiveness of small and medium-sized enterprises (SMEs), but there has been less research focusing on examining their use from the perspective of their antecedents. The proposed study aims to explain the antecedent factors that influence the continued use of cloud computing systems in Jordanian SMEs by employing an integrated approach that combines the Technology-Organization-Environment (TOE) framework, the Fit-Viability Model (FVM), and the Expectation-Confirmation Theory (ECT). A structured questionnaire survey was conducted to examine opinions from 276 Jordanian SMEs, which showed that relative advantage, perceived benefit, simplicity, adaptability, and perceived security are major antecedent factors in defining perceived appropriateness. Characteristics related to organizations, involving the importance of reading and the role of senior management members in organizations, are major antecedent factors in defining viability. Mimetic forces exerted in organizations are major antecedent factors that have a positive association in defining viability in organizations. On the other hand, coercive forces are major antecedent factors that have negatively affected viability in organizations. The appropriateness and viability of technologies are major antecedent factors in defining an individual’s desire to adopt cloud computing systems for an extended period of time in organizations. The proposed study suggests that the fitness of technologies is the most effective predictor of cloud computing system adoption in organizations. The proposed research study uses an integrated research theory that reflects on increasing the awareness needed to detail cloud computing systems. Cloud computing studies have never encountered such increased awareness before.

The Multiple Travelling Salesman Problem (MTSP) is one of the prominent combinatorial optimization problems with both theoretical interest and practical applications. However, its less-explored variants, such as the Open-Close Multiple Travelling Salesman Problem (OCMTSP), have received comparatively limited attention. In the OCMTSP, all salesmen commence their routes from a central depot, but unlike the classical MTSP, not all are required to return to the starting point upon completing their deliveries. Additionally, allowing any salesman to visit the maximum number of cities can lead to an imbalanced workload distribution among the salesmen. To address this imbalance, the current study incorporates a load balancing constraint into the OCMTSP framework, ensuring a fair distribution of cities among all salesmen. This extended problem variant is termed as Open-Close Multiple Travelling Salesman Problem with Load Balancing (OCMTSPLB). The primary objective of the OCMTSPLB is to minimize the total travel distance or cost incurred by the combined open and closed tours while maintaining balanced workloads. To solve this variant, the study proposes two distinct crossover based multi-chromosome Genetic Algorithm (GA) frameworks. Given the novelty of this problem, the algorithms are assessed using standardized benchmark instances from the TSPLIB. Experimental findings indicate that one of the proposed GA variants consistently achieves superior solution quality, a result further validated through non-parametric statistical tests.

Behavior-Based Safety (BBS) is the art of communicating and correcting unsafe behaviors of project and factory staff. It was developed from behavioral sciences through direct observations of behavior changes. Scholars across the globe have examined the efficacy of BBS in ensuring safe behaviors in projects. However, the available literature is fragmented, and there is a need to have a panoramic, systematic, and comprehensive understanding of BBS. This study synthesizes, analyzes, and categorizes the BBS literature to provide a conceptual framework and inputs for further research. The study was conducted using bibliometric analysis of 56 research articles from the Scopus database. The results present a bird's-eye view of published materials on BBS. The bibliographic coupling helped categorize the outcomes of BBS into various clusters. The study also found that most highly cited articles were from the construction industry. Future researchers may examine the findings of seminal studies, identified as the most cited documents, to inform design choices and trade-offs that address the major hindrances to implementing BBS in its true spirit.

This study investigates the key factors influencing intention to use e-commerce in an emerging market context, focusing on individuals residing in Saudi Arabia. A quantitative research approach was adopted, and data were collected using a structured questionnaire from 281 respondents through a convenience sampling technique. Data were analyzed using structural equation modeling with SmartPLS to test the hypothesized relationships. The results revealed that attitude, subjective norms, self-efficacy, and trust all had significant positive effects on intention to use e-commerce. Moreover, trust in e-commerce was found to influence attitude, which in turn mediated the relationship between trust and intention, highlighting the importance of trust as both a direct and indirect driver of online purchasing behavior. The R-square values indicated that 47.9% of the variance in attitude and 65.4% of the variance in intention were explained by the model, confirming strong explanatory power. The study concludes that trust, confidence, social influence, and positive attitudes are crucial for enhancing consumers’ willingness to engage in e-commerce. The study delivers essential information which helps e-commerce companies and marketing professionals and government officials to enhance consumer trust and digital shopping experience and build favorable digital commerce attitudes in Saudi Arabia.

Site clearance remains one of the most persistent causes of delay in Vietnam’s public infrastructure delivery, yet systematic evidence on how different stakeholders and project sizes perceive its underlying drivers is limited. This study investigates variations in stakeholder perceptions and project-scale effects on site clearance delays through an integrated analytical framework combining ranking, concordance, correlation, and variance analyses. Data were collected from key actors involved in land acquisition and clearance, including project owners, project management units, consultants, contractors, and land development centers, covering small, medium, and large public projects. Findings show that stakeholders share a general awareness of major delay causes but differ in prioritization based on institutional roles and responsibilities. Project owners, management units, and contractors emphasize coordination and staffing constraints, whereas consultants focus on technical and procedural issues, and land development centers view administrative and community challenges as routine. Across project sizes, perceptions diverge more strongly: small projects face capacity and resource shortages, large projects experience bureaucratic fragmentation and complex multi-agency coordination, and medium projects operate at a relatively balanced scale. These results indicate that project complexity increases nonlinearly with size, amplifying administrative and procedural burdens at both extremes. The study contributes by clarifying how institutional role and project scale shape perceptions of delay in Vietnam’s infrastructure sector. It underscores the need for scale-sensitive and role-specific management strategies to enhance the timeliness and effectiveness of site clearance processes.

The article presents the historical development of one of the most important forms of interaction between state power and private enterprise in countries of the federal type – public-private partnership (hereinafter referred to as PPP). The following world powers came forward as research objects: the United Kingdom of Great Britain and Northern Ireland, the French Republic, Canada, and the United States of America. However, first of all, the authors of the article presented and disclosed the main terms and their characteristics, such as genesis, partnership ofthe state and business, and also analysed their own programmes aimed at the development of interaction of the state and private business (for example, Private Finance Initiative, Private Finance 2) as well as development centres (such as the global centre Partnerships United Kingdom, the federal coordination centre Mission D’appui aux Partenariats Public-privé (Fr. Mission of Support of PPP) and others. Accordingly, after conducting a historical analysis, it was established that, firstly, the role of the state in the implementation of PPP projects is decisive, as in most cases it is their initiator and main organiser, and, secondly, the basis of the construction and further development of this form of interaction is the formation of its institutional environment based on legal norms, specialised public authorities, the country’s political course.

The article examines the current state of telemedicine project management in the Russian Federation (hereinafter referred to as RF). The authors emphasise the importance of compliance with medical standards and norms on the part of medical institutions, and the importance of updation of the regulatory framework in accordance with existing technologies on the part of government agencies regulating the medicine field. The main part of the article is devoted to the review of implemented projects in the modern field of healthcare – telemedicine: creation of a unified state information system in the sphere of healthcare; telemedicine network in the Yamalo-Nenets Autonomous District; telemedicine in the North-West of the RF (Arkhangelsk); “Children of the North” project. The authors have noted that projects in this area continue to develop, despite the problems and challenges of the environment. Special attention is paid to the difficulties faced by project teams, for example, the need to retrain doctors to work remotely without the possibility of a standard examination, only on the basis of the results of tests conducted on site. In addition, the problem of imperfect legislation regulating medical activities is discussed, which does not allow to use the telemedicine actively today. However, an analysis of modern practices of its application proves the effectiveness of this technology.
