Multidimensional analysis and characterization of vulnerabilities among project managers in engineering safety accidents
To systematically identify and analyze safety vulnerabilities in project management by project managers,as well as to enhance safety leadership and performance,publicly disclosed accident investigation reports from the Chinese construction sector(2013-2023)were utilized as the data source.BERTopic techniques were employed to extract vulnerability topics related to project managers in safety accidents,analyzing the distribution,evolution,and differentiation characteristics of these vulnerabilities from both static and dynamic perspectives.First,from a static perspective,the fitting transformation function module was employed to train the topic model,analyzing the number,distribution,and structure of vulnerability characteristics among project managers.Second,building on the static analysis results,the temporal topic function module was utilized for dynamic topic modeling to assess the evolution intensity of project manager vulnerabilities across different periods,thereby clarifying the temporal evolution patterns of various sub-dimensions of vulnerability.Finally,by utilizing the document information retrieval function module,the distribution of vulnerability topics among project managers across various project types was analyzed,providing clarity on the strategies and approaches for managing vulnerabilities in different project contexts.The results indicate that project manager vulnerabilities are primarily composed of 18 sub-dimensions,which encompass five key aspects:safety planning and training,accident reporting and handling,project systems and responsibilities,among others.Regarding evolutionary patterns,the intensity of vulnerabilities in 14 characteristics-such as inadequate hazard inspection and management,poor supervision of critical projects,and ineffective implementation of on-site duty systems-has shown a consistent increase over the years.In contrast,the other four characteristics exhibit an initial rise followed by a subsequent decline.Among construction,municipal,and highway projects with the highest incidence of accidents,vulnerabilities were most prevalent among project managers in the construction and municipal engineering sectors,while those in highway engineering were comparatively fewer.The research findings not only enhance the theoretical understanding of vulnerabilities within the realm of organizational management but also offer targeted guidance for diagnosing,addressing,and mitigating the vulnerabilities of project managers in safety-related incidents.
