The construction industry faces a high rate of safety accidents. Despite being a critical component of safety management, safety training often falls short of expectations. This shortcoming has been attributed to the insufficient integration of Learning Theories (LTs) and Instructional Design (ID) principles in Construction Safety Training (CST). This paper presents a systematic review of CST, incorporating insights from prominent ID sources, including ID elements (objective, session scheduling, content, tools and methods, learning tasks, and evaluation) and the most prominent LTs. The extent of adherence to these principles and theories in previous CST studies has been evaluated by reviewing 48 CST papers to identify opportunities for improvement. Recommendations for enhancing future CSTs include a) targeting Affective objectives, b) avoiding single-session condensed training, c) incorporating task-based training, d) conducting follow-up and long-term evaluations of knowledge and behavior, and e) incorporating LTs and Principles of Instruction explicitly and systematically. This study compared student training with site worker training, as well as training with and without computer tools, to identify gaps and provide tailored recommendations to improve each type of training. The findings lay the groundwork for integrating ID knowledge into CST, avoiding ID errors, and ultimately enhancing CST’s efficiency to reduce accidents.

The combination of multi-subject collaboration and organizational resilience strategies has recently become a significant research topic in disaster emergency response. Dynamically identifying emergency response network (ERN) resilience characteristics is essential for understanding multi-organizational collaboration and enhancing organizational response capabilities and efficiency. This study, from an integrated perspective of inherent resilience and adaptive resilience, proposed a dynamic analysis framework for ERN resilience. First, based on key resilience characteristics—adaptability, robustness, resourcefulness, and rapidity—an ERN resilience evaluation framework was constructed. The study then selected the 2022 Luding earthquake as a case study, dividing it into four periods and using social network analysis metrics to dynamically measure ERN resilience and its inherent organizational impact. The results showed that 1) earthquake ERN resilience exhibited dynamic adaptability and forward adaptability; 2) ERN resilience was significantly associated with organizational attributes and behaviors; and 3) ERN robustness was influenced by network cohesion and organizational distribution. Finally, recommendations were made to enhance disaster ERN resilience by optimizing organizational structure and responsibility allocation, improving emergency planning, and managing materials. This research provides a novel dynamic analytical framework for building disaster resilience and offers valuable insights into multi-stakeholder disaster governance for earthquake disaster resilience worldwide.

Preventing coal and gas outbursts is critical to maintaining safe and effective mining and a reliable energy supply in China. In order to solve the problems of accident chain uncertainty reasoning and a priori information ambiguity in outburst risk analysis, this paper explored the macroscopic causation mechanism based on 80 cases of coal and gas outburst accidents, constructed three types of hazards causation models using topological networks, developed a fuzzy Bayesian risk assessment model. The probability of coal and gas outburst accidents was assessed using causal reasoning, diagnostic reasoning, sensitivity analysis, and key causal path analysis, and the causative mechanism was discovered. The case study showed that: the probability of outburst in the working face of this mine was 1.3%; at the time of the accident, the probabilities of the occurrence of the second and third hazard increased by 1050% and 725%, respectively; through the analysis of the key causal paths, the probability of outburst caused by path 1 (abnormal geological conditions and organizational and management deficiencies) and path 2 (abnormal geological conditions and inadequate gas extraction) rose from the usual condition by 462.8% and 569.2%, respectively. Finally, the model was validated using two outburst accidents as samples, and the results revealed that the probability of outburst for the two accidental coal mines was 12% and 10%, respectively, and the critical causal paths were largely consistent with the accident investigation reports. The assessment model presented in this study can help managers effectively control outburst accidents.

Background

Recent research from Nordic countries observed higher levels of occupational physical activity (OPA) to increase mortality risk. However, research is required to clarify generalizability to other countries as several studies have found no or even an inverse association for certain subgroups.

Objectives

We aimed to investigate the association between OPA and mortality, retrieving administrative data from a Spanish population.

Methods

In a prospective cohort study, individuals from the Continuous Working Life Sample (CWLS), a representative sample with administrative registers of the workforce in Spain were followed up from baseline (January 1, 2006) to either death date or end of follow-up (September 1, 2019).

Results

During 13.6 years from baseline to the end of follow-up, 23,975 (3.2 %) of the participants died. The full adjusted model showed significant associations for men aged 18–36 years in moderate (HR, 1.54; 95 % CI, 1.26–1.88), high (HR, 1.26; 95 % CI 1.01–1.58), and very high OPA (HR, 1.44; 95 % CI, 1.15–1.80). Men aged 37–64 years solely showed a significant HR for moderate OPA (HR, 1.10; 95 % CI, 1.04–1.16), whereas no significant association was found in women.

Conclusion

These results warrant preventative measures to address early mortality among young working men in highly demanding physical jobs.

To investigate the influence and mechanism of resilience on flight performance under different flight situations, an experimental platform was built based on the PI135 flight simulation equipment, and three different flight situations were designed, including normal flight, single failure flight, and multiple failures flight, with the approach and landing phase as the object of the study. 27 flight cadets, who had completed the simulation flight training course and passed the assessment, were recruited as subjects to conduct the experiment. The flight operation evaluation indexes were determined, the flight operation evaluation model was constructed. Mental workload and flight operation performance of different flight situations, resilience and coping styles of flight cadets’ were measured respectively. The results of the experimental data analysis showed that there were significant differences in flight performance under three different flight scenarios, and that flight operation performance decreased with increasing mental workload. Under three different flight situations, the flight operation performance of the high resilience group was significantly better than that of the low resilience group. Moreover, as the level of mental workload increased, the decline in flight operation performance for the low resilience group was greater than that of the high resilience group. Resilience did not have a significant effect on flight operation performance under normal flight situations but had a significant positive effect on flight operation performance under non-normal flight situations, especially under multiple failure flight situations where the effect of the toughness dimension of resilience was significant. The mediating effect test showed that positive coping styles had a partial mediating effect between resilience and flight operation performance under multiple failure flight situations, with a mediating effect of 39.96%, and the mediating effect of negative coping styles was not significant.

Prioritizing occupational health and safety (OHS) in port operations is crucial for enhancing the industry’s competitiveness. This study aims to provide a comprehensive overview of the international literature on OHS risks in port operations and identify key strategies for promoting worker well-being. A systematic literature review was conducted using the Knowledge Development Process – Constructivist – ProKnow-C method, resulting in the selection of 42 international articles. Risk and strategy characterization were based on the framework proposed by Makin and Winder (2008). The findings reveal that 33.3% of the analyzed articles address or justify their findings based on the three areas of ‘safe person,’ ‘safe system,’ and ‘safe place’ simultaneously in the port sector. The study highlights the need for future research to deepen knowledge in this area, improving in an integrated way the understanding of occupational risk areas and the strategies implemented by the Occupational Health and Safety Management System (OHSMS) in the port environment.

Occupational accidents are common in construction projects. Although several previous studies have focused on this complex issue from different perspectives, such as predicting accidents for the general construction process, few studies have focused on the impact of project characteristics on the likelihood of accidents in building maintenance projects. Artificial intelligence-based predictive models for workplace accidents typically use ready-made algorithms or traditional methods like trial and error. Therefore, the main objective of this study is to predict the likelihood of occupational accidents in building maintenance projects by following a new feature selection process based on the topological approach. The information on the 1807 public school maintenance project was included in this study to test the proposed mathematical approach. Commonly used 7 different machine learning algorithms and a combination of these algorithms called a hybrid model was selected to apply the topological approach to the feature selection process. The results show that 5 out of 7 algorithms such as Stochastic Gradient Boosting (SGB), Extreme Gradient Boosting (EGB), Linear Discriminant Analysis (LDA), Gaussian Naive Bayes (GNB), and Hybrid (HYB) models show better performance after applying the topological technique. The main predictors of the likelihood of workplace accidents in these algorithms are site delivery (T2), cost breakdown ratio (F1), total duration (T1), and contractor size (P1). Using this approach, construction professionals can develop and implement more effective AI-based proactive safety management systems for maintenance projects.

Site managers have been said to perform one of the toughest jobs in the construction industry, which often requires them to work excessively long and irregular hours. Although previous research has reported on the detrimental effects of overwork on site managers’ wellbeing, few studies have examined their subjective reasoning related to these work patterns. Drawing on in-depth interviews with site managers in a large construction firm in Sweden, this study identifies two dominant narratives through which they justify excessive overwork: the narrative of advancement (which is career-oriented) and the narrative of preservation (which is autonomy-oriented). An analysis elucidates how these narratives encapsulate an ‘autonomy paradox’ which entraps the site managers in an endless loop of overwork, whilst convincing themselves that they are acting autonomously.

These results offer novel insights into why and how individuals who perceive themselves as autonomous enthusiastically engage in processes where they end up becoming ‘willing slaves’ to overwork. In a concluding part, the paper elaborates on how these findings contribute to two major fields of studies. First, they offer theoretical contributions to the literature on overwork and stress in the construction industry as well as practical advices to mitigate overwork. Second, they point at some contextual dimensions which have broader implications for organisation studies on overwork and stress. Most notable how certain contextual dimensions of project-based organizing can be viewed as permeating features of contemporary work-lives that continually allure us into happily overworking ourselves.

Hydrogen energy is one of the indispensable power sources and rail transit is one of main applications. The safety in tunnel is one of the major concerning issues related to the development of hydrogen powered rail transit, however, most previous studies are focused on open space and pipe scenarios. The effect of ignition time (10, 15 and 20 s) and mass flow rate (0.267, 0.324, 0.375 and 0.426 kg/s) on the inhomogeneous hydrogen distribution, the overpressure and propagation of the pressure wave and temperature distribution are studied numerically. The hydrogen diffusion distance and volume fraction increase with the increase of the leakage mass flow rate and leakage time. The pressure wave propagates to the tunnel exits horizontally and oscillates vertically. The high-temperature region touches and then spreads along the tunnel roof. Then it moves down to the floor and finally fills the entire space. The hydrogen volume fraction increases with the increase of leakage time and mass flow rate. Overpressure and temperature show a decreasing trend when ignition time and mass flow rate increases. Due to increase of hydrogen concentration participating in the chemical reaction, the explosion intensity is inhibited and shows a decreasing trend of explosion overpressure and temperature with increase of ignition time and mass flow rate.

Safety within aviation is defined by the effective management and mitigation of risks associated with aviation activities, encompassing direct aircraft operations and supporting functions. The safety management system (SMS), a holistic approach to proactively managing safety risks, is central to this endeavor. Comprising four integral components—safety policy and objectives, safety risk management, safety assurance, and safety promotion—the SMS hinges on a systematic risk management process. This study aims to understand the foundational principles for framing and executing organizational systems harmonized with the SMS and a risk-based approach within the realm of aviation maintenance organizations. Through a detailed literature review, this research discloses a concentrated focus on organizational factors, human factors, and managerial aspects within existing scholarship. Findings underscore the multifaceted nature of ensuring safety in aviation maintenance operations, clarifying the complicated bonds between organizational factors, human factors, and managerial aspects within this specialized context. Finally, we presented the essential characteristics of an SMS-integrated aviation maintenance organization, as derived from our comprehensive literature review.
