ABSTRACT
The study aims to examine the role of safety management practices and safety performance among nurses working in public hospitals amid the Coronavirus (Covid-19) pandemic in Nigeria. Self-administered questionnaires were distributed for data collection and a total of 229 nursing staff from the public health facilities in Abuja, Nigeria participated in the study. The results demonstrated that the level of safety performance was moderately high. These findings support the influence of management commitment on safety, safety training, and employees' involvement on safety compliance. It was also found that management commitment to safety, safety training, and safety promotion policies posed significant effects on safety participation. This study provides empirical support for the assertion that safety management practices are of paramount importance in improving safety performance among nurses in public hospitals, especially during the Covid-19 Pandemic.
ABSTRACT
Highway fatalities are a leading cause of death in the U.S. and other industrialized countries. Using highly detailed crash, speed, and flow data, we show highway travel and motor vehicle crashes fell substantially in California during the response to the COVID-19 pandemic. However, we also show the frequency of severe crashes increased owing to lower traffic congestion and higher highway speeds. This "speed effect" is largest in counties with high pre-existing levels of congestion, and we show it partially or completely offsets the "VMT effect" of reduced vehicle miles traveled on total fatalities. During the first eleven weeks of the COVID-19 response, highway driving decreased by approximately 22% and total crashes decreased by 49%. While average speeds increased by a modest 2 to 3 mph across the state, they increased between 10 and 15 mph in several counties. The proportion of severe crashes increased nearly 5 percentage points, or 25%. While fatalities decreased initially following restrictions, increased speeds mitigated the effect of lower vehicle miles traveled on fatalities, yielding little to no reduction in fatalities later in the COVID period.
ABSTRACT
The recent COVID-19 pandemic has led to a nearly world-wide shelter-in-place strategy. This raises several natural concerns about the safe relaxing of current restrictions. This article focuses on the design and operation of heating ventilation and air conditioning (HVAC) systems in the context of transportation. Do HVAC systems have a role in limiting viral spread? During shelter-in-place, can the HVAC system in a dwelling or a vehicle help limit spread of the virus? After the shelter-in-place strategy ends, can typical workplace and transportation HVAC systems limit spread of the virus? This article directly addresses these and other questions. In addition, it also summarizes simplifying assumptions needed to make meaningful predictions. This article derives new results using transform methods first given in Ginsberg and Bui. These new results describe viral spread through an HVAC system and estimate the aggregate dose of virus inhaled by an uninfected building or vehicle occupant when an infected occupant is present within the same building or vehicle. Central to these results is the derivation of a quantity called the "protection factor"-a term-of-art borrowed from the design of gas masks. Older results that rely on numerical approximations to these differential equations have long been lab validated. This article gives the exact solutions in fixed infrastructure for the first time. These solutions, therefore, retain the same lab validation of the older methods of approximation. Further, these exact solutions yield valuable insights into HVAC systems used in transportation.
ABSTRACT
PurposePsychosocial factors have received increasing attention regarding significantly influencing safety in the construction industry. This research attempts to comprehensively summarize psychosocial factors related to safety performance of construction workers. In the context of coronavirus disease 2019, some typical psychosocial factors are selected to further analyze their influence mechanism of safety performance.Design/methodology/approachFirst, a literature review process was conducted to identify and summarize relevant psychosocial factors. Then, considering the impact of the epidemic, hypotheses on the relationship between six selected psychosocial factors (i.e. work stress, role ambiguity, work–family conflict, autonomy, social support and interpersonal conflict) and safety performance were proposed, and a hypothetical model was developed based on job demands-resources theory. Finally, a meta-analysis was used to examine these hypotheses and the model.FindingsThe results showed these psychosocial factors indirectly influenced workers' safety performance by impacting on their occupational psychology condition (i.e. burnout and engagement). Work stress, role ambiguity, work–family conflict and interpersonal conflict were negatively related to safety performance by promoting burnout and affecting engagement. Autonomy and social support were positively related to safety performance by improving work engagement and reducing burnout.Originality/valueThis research is the pioneer systematically describing the overall picture of psychosocial factors related to the safety performance of construction workers. Through deeply discussed the mechanism of psychosocial factors and safety performance, it could provide a reference for the theory and application of psychosocial factors in the field of construction safety management.
ABSTRACT
AIM: To improve the level of hospital workers' safety performance in response to emergencies (e.g. COVID-19), this paper examines the relationship between hospital workers' job control on safety performance, and the mediating role of hospital safety climate and the moderating role of social support. DESIGN: In this cross-sectional questionnaire survey, a convenience sampling of hospital workers from three hospitals that have COVID-19 cases from Beijing and Shandong Province in China. METHODS: These questionnaires were used to obtain self-reported data on hospital workers' job control, hospital safety climate, social support and safety performance. Mplus software was used to calculate CFA. SPSS25.0 software was used to calculate mean values, standard deviations, correlations and regression analyses. RESULTS: The participants were 241 hospital workers from three hospitals in China (male = 55.2%, female = 44.8%; age range <30 to >45; physician = 58%, nurse = 22%, other hospital worker = 20%). A moderated mediation model among job control, hospital safety climate, social support and safety performance was supported. Moderated mediation analysis indicates hospital workers' job control effectively improves the level of safety performance; hospital safety climate plays a partially mediating role in the process of job control affecting hospital workers' safety performance; social support moderates the effect of work control on medical workers' safety climate. Hence, it is important to increase job control and hospital safety climate. Further, social support for hospital workers should be encouraged, advocated and supported.
ABSTRACT
The coronavirus (COVID-19) pandemic was recognized as a worldwide epidemic and classed as a high risk in early 2020, affecting people's health, economies, and business sectors considerably. This pandemic has had an impact on people's lifestyles and work processes in a multitude of sectors. The construction industry is one such industry that has had a substantial influence on it. However, this influence needs to be measured in different areas. This study aims to measure the effects of the COVID-19 on the 7 core safety elements and their 24 procedures that are derived from the recommended practices for safety and health programs in construction that is issued by OSHA to see whether their priorities have been changed or not. The data were collected and then analyzed using Relative Importance Index (RII) to study the changes in their priorities;and using t-test to study the significance of the changes before and after COVID-19 pandemic.(c) 2022 THE AUTHORS.

ABSTRACT
This study examined the impact of work-family conflict on subway employees' safety performance during the initial wave of the COVID-19 pandemic. We proposed a chain mediation model in which job burnout and affective commitment play mediating roles in this process. Using questionnaire data from 632 Chinese subway employees during February 2020, structural equation modeling analyses were performed. The analyses showed that work-family conflict had a significant negative impact on subway employee safety performance. Moreover, job burnout completely mediated the influence of work-family conflict on safety performance, while affective commitment only partially mediated the influence of job burnout on safety performance. These findings suggest the important role played by Work-Family balance during the pandemic and contribute to a deeper understanding of the inner mechanisms. We also discussed several practical implications for organizations to reduce the negative impact of work-family conflict on safety performance.

Sustainability of large transport infrastructure projects is directly linked with the working conditions and procedures in construction and maintenance. Furthermore, safety is one of the most crucial performance indicators for transport infrastructure operators, dealing with management priorities, policies and measures closely related to Occupational Health and Safety (OHS). This issue is extremely important especially for public private partnerships (PPP), extensively adopted in transport sector in many regions, where detailed contacts and OHS provisions should be considered. By a systemic analysis, this research identifies the key management factors influence safety performance in the PPP/concession projects and the management comprehensives over those factors. The survey analysis framework for the evaluation of OHS management performance for large transport operators are breakdown, promoting the structure and the expected outcomes toward sustainable management of transport infrastructure. The application is the Greek motorways concessions projects that implemented in the last decade. The research outputs provide key messages to planners, managers, decision makers, and stakeholders over large transport infrastructure sustainable development, promoting OHS performance aspects should be taken into consideration in operation management contacts and highlighting the link between OHS, level of safety, and sustainability. The case study structure and outputs are valuable for comparisons with similar cases, provide the framework for using in other places and/or cases and stimulate the interest for further research.

ABSTRACT
The main purpose of this research was to investigate the mediating role of safety communication (SCO) in the relationship between safety culture (SC) and safety performance (SP) amongst employees in the petrochemical industry. Safety communication methods not only enhance working conditions but also have a positive impact on employee's behaviors and attitudes toward safety leading toward reduced incidents in the workplace environment. A stratified sampling method was followed to collect data in the petrochemical industry in Malaysia. Structural equation modeling (SEM) was utilized to analyze the hypothesized model, using data from 320 participants. The findings reveal that safety communication partially mediates the association between safety culture and safety performance. Further, safety culture was found to have a significant and positive effect on safety performance. This -study makes a significant theoretical contribution by providing empirical evidence on the direct and indirect relationship between safety culture and safety performance in the petrochemical industry.

The innovative concept of digital tower provides a new solution for reducing the construction and operation costs of airports with adverse natural environments, poor intervisibility conditions, or sparse traffic. However, it leads to changes in the situational awareness of air traffic controllers and to challenges in safety performance. To research the safety performance of apron controllers at a large-scale airport applying a digital tower, a field study was conducted at Baiyun International Airport in Guangzhou, China. In this study, we established a comprehensive index system from the perspective of situational awareness, which provided measurements on the areas of interests, gaze and physiological features, and vigilance of controllers. Three modules were compared: a physical tower module, a digital tower module with a large panoramic screen, and a digital tower module with a small panoramic screen. The differences in the safety performances of apron controllers are discussed in two aspects: adaptability and reliability. The results indicated that the apron controllers at the three modules performed different cognition patterns, but similar cognition effort was paid toward maintaining performance. Furthermore, the significant vigilance decrement of controllers exists between after-duty and before-duty, but with no significant difference among the three modules. In conclusion, apron controllers at a large-scale airport could obtain effective safety performances based on a digital tower that were no less than those from a physical tower.

This study develops and tests a research model to explain and predict how and when organizational safety climate influences hospitality employees' safety performance behaviors by proposing two boundary conditions: communication transparency and safety-related stigma based on expectancy-valence theory. Specifically, we examined if communication transparency intensifies the impact of perceived safety climate on employees' safety motivation that drives safety performance behaviors through prevention work focus and if safety-related stigma attenuates the links between safety motivation and safety performance behaviors. Based on two national samples of 214 South Korean and 240 U.S. foodservice employees, this research found that safety climate was positively associated with safety motivation, prompting safety behaviors with the key mediating mechanism of prevention focus work. However, there were different patterns observed for the moderating roles of communication transparency and stigma for the foodservice employees between South Korea and the United States. Implications of the findings are discussed for hospitality researchers and practitioners.
