Safety climate: Systematic literature network analysis of 38 years (1980-2018) of research

An interpretable clustering approach to safety climate analysis: Examining driver group distinctions

The transportation industry, particularly the trucking sector, is prone to workplace accidents and fatalities. Accidents involving large trucks accounted for a considerable percentage of overall traffic fatalities. Recognizing the crucial role of safety climate in accident prevention, researchers have sought to understand its factors and measure its impact within organizations. While existing data-driven safety climate studies have made remarkable progress, clustering employees based on their safety climate perception is innovative and has not been extensively utilized in research. Identifying clusters of drivers based on their safety climate perception allows the organization to profile its workforce and devise more impactful interventions. The lack of utilizing the clustering approach could be due to difficulties interpreting or explaining the factors influencing employees' cluster membership. Moreover, existing safety-related studies did not compare multiple clustering algorithms, resulting in potential bias. To address these problems, this study introduces an interpretable clustering approach for safety climate analysis. This study compares five algorithms for clustering truck drivers based on their safety climate perceptions. It also proposes a novel method for quantitatively evaluating partial dependence plots (QPDP). Then, to better interpret the clustering results, this study introduces different interpretable machine learning measures (Shapley additive explanations, permutation feature importance, and QPDP). The Python code used in this study is available at https://github.com/NUS-DBE/truck-driver-safety-climate. This study explains the clusters based on the importance of different safety climate factors. Drawing on data collected from more than 7,000 American truck drivers, this study significantly contributes to the scientific literature. It highlights the critical role of supervisory care promotion in distinguishing various driver groups. Moreover, it showcases the advantages of employing machine learning techniques, such as cluster analysis, to enrich the scientific knowledge in this field. Future studies could involve experimental methods to assess strategies for enhancing supervisory care promotion, as well as integrating deep learning clustering techniques with safety climate evaluation.

The role of organizational factors in promoting workers' health in the construction sector: A comprehensive analysis

INTRODUCTION

The number of physical and mental problems caused by occupational accidents and diseases increases every year. To control them, the safety climate at work is a recognized critical factor. However, a widely applicable model to capture the safety climate for various industries and organizations is lacking.

METHOD

This study proposes a theoretical model to measure the direct and indirect effects of safety climate on workers' physical and mental health, mediated by job satisfaction, in the construction sector. We propose a multidimensional construct of safety climate, considering the most salient factors from the literature, and including psychological capital as a new factor. Using data from the last wave of the European Working Conditions Survey (2015) in Spain, the proposed model was validated using structural equation modeling.

RESULTS

Our findings suggest that to further improve the mental health of construction workers, work-life balance and job rewards and compensation must be prioritized along with safety climate. As for physical health, safety climate and work-life balance are crucial. Finally, we provide some recommendations for construction company managers based on a ranking of all the factors affecting the safety climate and the workers' health.

Global scientific trends in healthy aging in the early 21st century: A data-driven scientometric and visualized analysis

Background

According to the World Health Organization (WHO), healthy aging is the process of developing and maintaining the functional capacity for health in old age. A rapidly growing number of research studies on healthy aging have been conducted worldwide. The purpose of this research work is to explore global scientific landscape of healthy aging research over the last 22 years.

Methods

Scientific publications on healthy aging from January 1, 2000 to October 11, 2022 were retrieved from the Web of Science Core Collection (WoSCC) on October 11, 2022. A total of 6420 publications were included in the scientometric analysis. VOSviewer (1.6.18) was used to conduct scientometric and visualized analysis.

Results

The publication growth rate was 35.68 from 2000 to 2021. The United States of America (USA) led in both productivity and citations. PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA was prominent in terms of both the highest citation count and the highest average citation count. The National Institute on Aging (NIA) and Evans, Michele K. were the most influential organization and author, respectively. Research hotspots in healthy aging were identified based on the co-occurrence analysis of keywords: (1) physical activity and mental health of older adults; (2) diseases impacting the health and lifespan of older adults; and (3) neuroscience. Our analysis indicates that gut microbiota, loneliness, frailty, mitochondria and resilience were the emerging themes in healthy aging research.

Conclusions

The quantity of annual publications on healthy aging has rapidly increased over the past 22 years, especially during 2018-2021. This analysis identified the status, trends, hot topics, and frontiers of healthy aging research. These findings will help researchers quickly understand the global representation of healthy aging research, influence resource dissemination, promote international collaborations, guide policy formulation, and improve health services for older adults.

Safety climate and safety behaviors: Adapting and validating a positively worded safety climate scale through the time-lagged approach

BACKGROUND

Contemporary literature raises serious questions about the inclusion of negatively worded items in the safety climate scale. Despite these reservations, limited efforts have been made to address this shortcoming.

OBJECTIVE

The present study aims to adapt and empirically validate the ten-items group-level safety climate scale with the purpose of replacing negatively worded items with positively worded ones after a thorough validation process. The present study is one of the first to propose an empirically validated group-level safety climate scale that uses positive items to measure the safety climate construct.

METHODS

Study 1 was conducted using a sample of 135 participants. Study 2 used a time-lagged approach to validate the scale, with a sample of 173 production workers from six oil and gas organizations in Malaysia. The Partial Least Squares Structural Equation Modeling (PLS-SEM) method was used to test the hypothesized relationships.

RESULTS

In Study 1, the results of the exploratory factor analysis showed good reliability for the revised scale. In Study 2, the results of the PLS-SEM analysis demonstrated a positive relationship between safety climate and safety behaviors, thereby validating the revised and translated scale of safety climate.

CONCLUSION

The revised safety climate scale will not only improve data quality, but it will also increase response rates. Additionally, the revised scale will assist managers in understanding the true perceptions of safety climate in their organization, regardless of the cultural context in which the scale is used.

Human exposure to heavy metals and related cancer development: a bibliometric analysis

As notifications on carcinogenicity of heavy metals increase, more and more attention is paid recently to heavy metals exposure. In our study, the human exposure to heavy metals and cancer knowledge epistemology was investigated using bibliometric analysis. The bibliometric data of the research articles were retrieved using following keywords: "heavy metal," "trace element", "cancer", "carcinogen", and "tumor" in the Scopus database. Specifically, 2118 articles published between 1972 and 2023 were found, covering a total of 1473 authors, 252 sources, and 2797 keywords. Retrospective data obtained from 251 documents and 145 journals were further analyzed by performance analysis and techniques of science mapping. The number of studies conducted in this field increased from one article published in 1972 to 18 articles published in 2022 in the study of Michael P Waalkes. The most impactful author regarding the number of published papers was Masoudreza Sohrabi with 7 publications. In the majority of the published papers, the most popular keywords were "cadmium" and "carcinogenicity". However, in recent 4 years, the emphasis has been placed more on epidemiology studies. Our study provides general knowledge about the trend of publication on the role of heavy metals in causing cancer. The leading researchers in the field of the effects of heavy metals on the development of cancer were identified in our studies. Our results might also create a better understanding of new and emerging issues and can be used as a comprehensive road map for future researchers.

The Role of Wellness Climate in Small Business Health Promotion and Employee Wellbeing

Wellness involves physical, emotional, behavioral, social, and spiritual dimensions. A climate for wellness exists at both the psychological and organizational levels, consisting of individual and shared perceptions of policies, structures, and managerial behavior that support or promote employee wellbeing. This study explored the associations between psychological and organizational wellness climate and the effectiveness of a team health promotion training on employees' perceived physical and mental wellbeing and substance use. Employees from 45 small businesses completed self-report measures of wellness climate, wellbeing, positive unwinding behavior, work-family conflict, job stress, drug use, and alcohol use, assessed before, and one and six months after, attending either of two types of onsite health promotion training. Team Awareness training targeted improvements in the social climate at work. Healthy Choices training targeted individual health behavior. A control group did not receive training until after the study. Businesses were randomly assigned to conditions and data were analyzed using multi-level modeling. Models that included wellness climate as a mediator fit the data significantly better than models without climate as a mediator. Team Awareness participants showed greater improvements in wellness climate and wellbeing compared to the control group. Healthy Choices participants showed no changes in climate and no mediation effects of climate. Health promotion efforts may be enhanced by including wellness climate as a target in program design at multiple levels.

Safety Climate Assessment in Fuel Stations in the West Java Region

Fuel station accidents still happen frequently all around the world. Accidents in fuel stations may cause harm to many. Fuel station environments must thus be managed well to maintain a high safety climate level. However, our literature review shows that research on the safety climate in fuel stations is scarce. This study attempts to assess the safety climate level in fuel stations in the West Java region, Indonesia. The aims of this research are to acquire the safety climate level of fuel stations, review safety climate dimensions which need serious improvement, and discover key aspects that impact the safety climate level. To achieve these goals, the Bahasa Indonesia version of the NOSACQ-50 questionnaire was used to assess the safety climate in 240 fuel stations; 678 responses were collected. The findings show that the safety climate level of fuel stations was, on average, 3.07, which is a fairly good score. Among all seven dimensions, workers’ safety priority and risk non-acceptance need the most improvement. Moreover, safety training is found to be the most influential aspect on safety climate because workers with training experience have higher safety climate perceptions. Ironically, more than 28% of respondents reported that they had not been properly trained. Therefore, fuel stations need to make sure that all employees have attended appropriate safety training. In this way, higher safety climate ratings can be achieved, hence moving forward to a safer working environment.

Understanding the domain of driving distraction with knowledge graphs

This paper aims to provide insight into the driving distraction domain systematically on the basis of scientific knowledge graphs. For this purpose, 3,790 documents were taken into consideration after retrieving from Web of Science Core Collection and screening, and two types of knowledge graphs were constructed to demonstrate bibliometric information and domain-specific research content respectively. In terms of bibliometric analysis, the evolution of publication and citation numbers reveals the accelerated development of this domain, and trends of multidisciplinary and global participation could be identified according to knowledge graphs from Vosviewer. In terms of research content analysis, a new framework consisting of five dimensions was clarified, including "objective factors", "human factors", "research methods", "data" and "data science". The main entities of this domain were identified and relations between entities were extracted using Natural Language Processing methods with Python 3.9. In addition to the knowledge graph composed of all the keywords and relationships, entities and relations under each dimension were visualized, and relations between relevant dimensions were demonstrated in the form of heat maps. Furthermore, the trend and significance of driving distraction research were discussed, and special attention was given to future directions of this domain.

The Atmospheric Environment Effects of the COVID-19 Pandemic: A Metrological Study

Since the COVID-19 outbreak, the scientific community has been trying to clarify various problems, such as the mechanism of virus transmission, environmental impact, and socio-economic impact. The spread of COVID-19 in the atmospheric environment is variable and uncertain, potentially resulting in differences in air pollution. Many scholars are striving to explore the relationship between air quality, meteorological indicators, and COVID-19 to understand the interaction between COVID-19 and the atmospheric environment. In this study, we try to summarize COVID-19 studies related to the atmospheric environment by reviewing publications since January 2020. We used metrological methods to analyze many publications in Web of Science Core Collection. To clarify the current situation, hotspots, and development trends in the field. According to the study, COVID-19 research based on the atmospheric environment has attracted global attention. COVID-19 and air quality, meteorological factors affecting the spread of COVID-19, air pollution, and human health are the main topics. Environmental variables have a certain impact on the spread of SARS-CoV-2, and the prevalence of COVID-19 has improved the atmospheric environment to some extent. The findings of this study will aid scholars to understand the current situation in this field and provide guidance for future research.

A tale of six climates: Reflections and learnings after the development of six industry-specific safety climate scales

INTRODUCTION

Researchers are finding merits in utilizing industry-specific safety climate scales that capture the nuances of context, and tend to show stronger associations with safety behavior and outcomes like incidents. Yet, to date, guidance around the practicalities of developing and validating such industry-specific scales is lacking in the safety science literature.

METHOD

In this paper we outline our experiences developing six industry-specific safety climate scales and highlight strengths and limitations of our approach. We also briefly review the industry-specific safety climate literature and offer highlights for consideration when developing such scales. Our method to develop industry-specific safety climate scales followed an established best practice structure: literature review of existing published industry scales, collation and review of existing scale items, consultation interviews with industry experts, item drafting, exploratory and confirmatory statistical analyses, and finally, a real-world ecological validity test.

RESULTS

Our research highlighted the diversity of safety climate dimensions (both the conceptual and content domains of each dimension) when it is considered at an industry level. Also, the literature reviews revealed a dearth of industry-specific safety climate scales in the areas we engaged with, so our project filled a glaring gap in research and practice. Best practice safety climate scale development methods are provided to stimulate further research.

CONCLUSIONS

We conclude with reflections on the nature of safety climate within and across industries, and offer suggestions for future lines of research across other contexts (e.g., national culture, geography, and regulatory settings). We suggest that industry-specific safety climate scales have a specific use case, such as identifying specific areas to improve and evaluating the impact of safety interventions.

PRACTICAL APPLICATIONS

This article provides applications for both applied researchers (to improve capabilities in safety climate scale development) and practitioners who wish to measure organisational safety climate and design effective interventions. Engaging with regulators to build safety climate scales is powerful because their personnel have rich experiences to share across multiple workplaces. Organisational researchers can engage with survey panels to build robust scales. Finally, industry-specific nuances can lead to richer insights into an organisation's safety climate.

International Research Progress in School Travel and Behavior: A Literature Review and Bibliometric Analysis

A deep understanding of school travel mode can help policymaking related to the optimization of the school travel structure, alleviating urban traffic congestion due to the increasingly prominent phenomenon of urban sprawl. However, existing studies in this field are based on a specific research perspective, and comprehensive reviews are rather limited. Therefore, this study aims to provide an in-depth, systematic review of school travel by using bibliometric analysis. Firstly, based on the Web of Science, TRID, ScienceDirect, and MEDLINE databases, 457 studies about school travel are selected from between 1996 and 2021. Secondly, utilizing bibliometric analysis, the research progress is summarized with emphasis on the annual performance of the literature, publication status of a country or region, literature source institutions, keywords of the literature, and co-citation network analysis. The research results show that (1) the United States, Canada, and Australia rank top in the number of studies on school travel, and they also have high citation frequency and connection strength. (2) This study collects studies published in 34 journal publications, and the “Journal of Transport & Health” is the main source for publishing research. (3) The choice of school travel mode is significantly affected by individual characteristics, family conditions, and social status. The built environment and parental factors play a leading role in students’ active travel to school, and independent mobility and active transport contribute to students’ healthy development. However, policy planning is necessary to further improve the transportation infrastructure sustainability and school route safety. (4) Finally, several promising directions and potential limitations are discussed for developing countries based on the research progress in developed economies.

The effect of an embargo, sanctions and culture on safety climate: A qualitative view from aviation maintenance in the MENA region

INTRODUCTION

Safety climate assessment is a key measure of organizational safety. A strong safety climate is integral to the high safety performance in aviation. Most survey instruments that purport to measure safety climate are derived from evidence obtained in developed countries in the west. It is rare for these studies to examine the influence of macro-environmental factors on safety climate, and rarer still in countries found in the Middle East and North Africa (MENA) region.

METHOD

The researchers conducted 28 semi-structured interviews with experienced aviation maintenance engineers from a national carrier in the region. The interview questions were derived from an extensive review of existing studies of safety climate. Data from interview transcripts were coded, creating a data structure using participant quotes for 1st order codes and arriving at three aggregate dimensions: organizational commitment to safety, organizational safety practices and social relationships and their consequences.

RESULTS

Commercial considerations influenced negatively organizational commitment to safety. Organizational safety practices were weak. There was a lack of safety training, a lack of resources to support safe working, poor safety communication, and a failure to report safety issues. Strong friendships were developed through working together in teams. This adversely influenced the reporting of errors and the punishment of violations.

DISCUSSION AND CONCLUSION

The apparently weak organizational safety climate reported here was attributed to financial constraints following the imposition of economic sanctions and embargos, and to the influence of Arabic cultural values that privilege family connections and the importance of maintaining harmony in social relationships that precludes punishment.

PRACTICAL APPLICATION

Financial constraints inevitably limit resources for safety and encourage prioritization of production. Arabic cultural values inhibit the development of a 'just' culture and a 'reporting' culture and challenge the universal adoption of approaches for promoting organizational safety developed in the West.

Prioritization of leading operational indicators in occupational safety and health

New approaches are necessary to ensure the effectiveness of an Occupational Safety and Health Management System (OSHMS), which include the development of new methods that would facilitate the measurement of the proactive operational status. This study addresses the development of a tool that contains leading operational indicators in Occupational Safety and Health (OSH), with the main objective of prioritizing these indicators according to the consensual opinion of groups of experts. The Delphi method was applied to this manageable list to prioritize the indicators through three rounds, and a consensus was obtained on which indicators are most relevant, both for each individual group of experts and for all experts. This tool allows each company to customize the indicators that are most appropriate for its own reality by considering the report of these indicators. This tool can be a part of a safety dashboard model and considers only the most relevant indicators.

Bibliometric analysis of articles on nanoemulsion and/or in-situ gel for ocular drug delivery system published during the 2011–2021 period

The bibliometric data were extracted from the Scopus database to investigate the conceptual framework of ocular nanoemulsion and/or in-situ gel drug delivery system using “ocular” AND “nanoemulsion” OR “in-situ gel” keywords. The data were evaluated with RStudio and VOSviewer program.

The results reveal that the publication trends tend to increase continually. India is the most impactful country, and the most constructive institution is Department of Pharmaceutics and Industrial Pharmacy, Faculty of Pharmacy, Cairo University. International Journal of Pharmaceutics is the top influential source. Ali A is the most prolific author. The title of the most impactful article was In-situ gelling systems based on Pluronic F127/Pluronic F68 formulations for ocular drug delivery”. “Controlled release” is the most popular keyword.

These results provide insights for stimulating research collaborations and revealing open issues of controlled-release ocular preparation to overcome an ocular barrier and enhance patient compliance.

Occupational Safety Climate in the Swedish Equine Sector

The Swedish equine sector is considered a high-risk work environment, with relatively high injury rates and high severity of injuries. General safety research has identified a correlation between the safety performance and safety culture, but little is known about the intricacies of the safety culture in the Swedish equine sector, especially concerning managers' and employees' perceptions of their work environment. The safety climate assessment is recognised as an effective tool for identifying potential problems in the workplace, thus enhancing safety behaviour and decreasing the frequency and severity of injuries. The aim was to evaluate the safety climate at riding schools and trotting stables through the Nordic Safety Climate Questionnaire (NOSACQ-50) diagnostic tool, and to get a better understanding of the workers' perceptions regarding safety and safety management at their workplace through complementary interviews. The results showed that the safety climate was generally positive and that employees were aware of the risks relating to their work. Riding schools commonly had routines in place for risk assessment and work environment management, but such routines were often lacking at trotting stables, indicating inadequate prioritisation of safety by the management. The main area that should be targeted to improve safety in the sector is employees' prioritisation and non-acceptance of risks. Proactive instead of reactive safety management should be promoted, where safety is an integral part of daily work and all employees are encouraged to identify factors contributing to occupational injuries and develop strategies for injury prevention.

Development and testing of a tool to measure the organizational safety climate aboard US Navy ships

INTRODUCTION

Safety climate is a critical human factor that can increase safety-related behaviors and reduce accidents. This research reports on a three-phase program of development and validation of a safety climate survey tool initiated by U.S. Naval Surface Forces after numerous accidents and near misses.

METHOD

The initial survey was administered to 4,042 sailors aboard 30 warships, and factor analysis supported a three-factor measure of a safety climate composed of operational compliance, positive work environment, and organizational resources. The predictive validity of the newly developed safety climate measure was tested against the number of accidents reported in the 12 months after the safety climate survey.

RESULTS

This analysis revealed that a positive work environment and operational compliance were linked to fewer accidents; surprisingly, organizational resources were linked to more accidents. Implications for future research on safety climate and occupational safety are discussed.

Behavioral Theories That Have Influenced the Way Health State Preferences Are Elicited and Interpreted: A Bibliometric Mapping Analysis of the Time Trade-Off Method With VOSviewer Visualization

Aim

The aim of this paper is to develop an understanding of how behavioral theories have influenced the way preferences for health-related quality of life are elicited and interpreted. We focus on the Time Trade-off (TTO) method given it represents the quality-adjusted life-year (QALY) concept-that survival in less-than-full health can be deemed equivalent to a shorter survival in full health. To our knowledge this is the first review using a combination of systematic scoping review, bibliometrics and VOSviewer visualization to map the development of ideas in health economics.

Methods

A priori, we selected three behavioral theories to explore within our review, referred to here as Expected Utility Theory, Non-Expected Utility Theory and Probabilistic Choice Theory. A fourth topic, Order Effects, is defined broadly to encompass behavioral theories around timing/sequence of events. For the main search, Scopus was used to identify literature that had (a) elicited TTO values and/or (b) contributed to the way TTO values were elicited and interpreted, from inception to July 2021. Papers that focused on the latter category were given the label "behavioral" and underwent additional analyses. A two stage-screening was applied to assess eligibility. Co-citation, co-authorship and co-occurrence of keywords was used to chart the development of TTO over time.

Results

A total of 1,727 records were retrieved from Scopus and were supplemented by an additional 188 papers. There were 856 applied and 280 behavioral papers included in the final corpus, with the behavioral set split equally into four sets of 70 papers to chart the development of keywords over time: (1) 1972-1999; (2) 2000-2010, (3) 2010-2015 and (4) 2015-2021.

Discussion

The keyword analysis suggested that whilst some ideas transition quickly from economic theory to the TTO literature, such as the impact of Order Effects, others take longer to be assimilated, for example Non-Expected Utility models or failure of constant discounting. It is therefore important that researchers within health economics work more closely with those in mainstream economics and keep abreast of the wider economics and behavioral sciences to expedite the uptake of new and relevant ideas.

Measuring Safety Climate in the Construction Industry: A Systematic Literature Review

Recent studies on safety in various fields use the concept of safety climate to explain the causes of safety accidents. Many studies attempt to measure the safety climates and identify the causes for accidents in the high-risk construction industry. Studies have shown that the higher the level of the safety climate, the lower the accident rate at construction sites. Methods of measuring safety climate, including the NOSACQ-50 survey, have been presented. Studies on the methodology of measuring safety climate should be continued to improve reliability and precision. Although many studies have been conducted to measure safety climate, such as questionnaires, regression analysis, and suggestions for safety climate measurement methods, there are few studies on a systematic literature review of them. This requires a systematic literature review (SLR) of the studies conducted so far. This study conducted an SLR on the definition and measurement methods of safety climate in the construction industry published since 2000, when safety climate’s impact on accidents began to be established. This review study utilized the PRISMA method, analyzed 735 studies, and selected 57 papers finally. SLR was carried out for selected research works, and the results were summarized. There are three methods to measure safety climate: literature survey, questionnaire, and data analysis. Factor analysis, development of measuring model, development of questionnaire, statistical analysis, and machine learning were investigated as their sub-methods. This study’s results can be used as fundamental sources for improving existing methods and developing new methods of measuring safety climate in the construction industry.

Life Cycle Assessment and Material Flow Analysis: Two Under-Utilized Tools for Informing E-Waste Management

The unprecedented technological development and economic growth over the past two decades has resulted in streams of rapidly growing electronic waste (e-waste) around the world. As the potential source of secondary raw materials including precious and critical materials, e-waste has recently gained significant attention across the board, ranging from governments and industry, to academia and civil society organizations. This paper aims to provide a comprehensive review of the last decade of e-waste literature followed by an in-depth analysis of the application of material flow analysis (MFA) and life cycle assessment (LCA), i.e., two less commonly used strategic tools to guide the relevant stakeholders in efficient management of e-waste. Through a keyword search on two main online search databases, Scopus and Web of Science, 1835 peer-reviewed publications were selected and subjected to a bibliographic network analysis to identify and visualize major research themes across the selected literature. The selected 1835 studies were classified into ten different categories based on research area, such as environmental and human health impacts, recycling and recovery technologies, associated social aspects, etc. With this selected literature in mind, the review process revealed the two least explored research areas over the past decade: MFA and LCA with 33 and 31 studies, respectively. A further in-depth analysis was conducted for these two areas regarding their application to various systems with numerous scopes and different stages of e-waste life cycle. The study provides a detailed discussion regarding their applicability, and highlights challenges and opportunities for further research.

NOSACQ-50 for Safety Climate Assessment in Agricultural Activities: A Case Study in Central Italy

Safety climate assessment has been recognized as a powerful tool to bring to light workers' perceptions related to safety practices, attitudes and behaviors at the workplace. Accordingly, its investigation can provide useful information about safety problems within a company before accidents occur. In literature, numerous studies can be found investigating safety climates in different types of industry. However, safety climate assessment in agricultural activities is addressed scarcely, even though agriculture represents a very hazardous sector. To reduce this gap, the present study proposes an investigation of safety climate among farmers by means of the Nordic Safety Climate Questionnaire (NOSACQ-50). The results of the survey brought to light a low level of safety perception of the interviewed sample, especially as concerns safety commitment and risk-taking attitudes. In particular, a different attitude toward safety issues has been registered depending on both the position and gender of the interviewed farmers. Overall, the output of this cross-sectional analysis adds to the current literature by expanding knowledge of safety climate among farmers, representing a baseline for further investigations based on human-centered approaches to enhance safety in agriculture and consequently social and workplace aspects of sustainable agricultural systems.

Antecedents of safety behavior in construction: A literature review and an integrated conceptual framework

There has been no scarcity in the literature of suggested antecedents of employee safety behavior, and this paper brings together the disaggregated antecedents of safety behavior in the construction field. In total, 101 eligible empirical articles are obtained. Bibliometric and context analyses are combined to identify the influential journals, scholars, keywords, use of theory, research methods, and countries or regions of the empirical samples. The 83 factors that are identified are divided into five groups, namely (a) individual characteristics, (b) workgroup interactions, (c) work and workplace design, (d) project management and organization, and (e) family, industry, and society. This indicates that the causes of safety behavior are manifold. Various factors from different systems likely work in concert to create situations in which an individual chooses to comply with safety rules and participate voluntarily in safety activities. Given this, we propose that safety behavior is only an ostensible symptom of more complex "The Self-Work-Home-Industry/Society" systems and establish a safety behavior antecedent analysis and classification model. Based on this model, we develop a resource flow model, illustrating why, how, and when the flow of resources between the five systems-namely the self system, work system, home system, work-home interface system, and industry/society system-either promotes or inhibits safety behavior. The safety behavior antecedent analysis and classification model and resource flow model are based mainly on bioecological system theory and resources theories. Avenues for future theoretical development and method designs are suggested based on the reviewed findings and the two conceptual models. The intention with this systematic review together with the two integrated conceptual models is to advance theoretical thinking on how safety behavior can be promoted, or instead, inhibited.

Analysis of Safety Management Characteristics Using Network Analysis of CEO Messages in the Construction Industry

Chief executive officer (CEO) messages are important in communicating with employees. In terms of sustainability management, it is important to study these messages for their finance and safety content; however, previous studies have focused mostly on the financial aspects. Therefore, our approach is to: (1) focus on safety management, (2) use text mining and network analysis to extract the keywords emphasized by the CEOs, (3) analyze safety management characteristics through factor mapping and network analysis, (4) make recommendations. When the results from the CEO communications of 100 global construction companies were reviewed, keywords including “management”, “value”, “employee”, “system”, “project”, “culture”, “new”, “occupational”, “practice”, and “basis” were deduced. The words “management”, “employee”, and “culture” were the common keywords considered important by CEOs and were highlighted in literature reviews as significant words. Both the deduced keywords and the words deemed important by the CEOs have similar connotations. Motivation, Rules and Regulations, and Resources and Equipment were the factors that exhibited the highest centrality, while Culture and Climate had a structurally high connection. Based on our results, we suggest selecting appropriate words to form consensus with the workers, supplementing the factors related to safety investment with low centrality, and using direct “safety” words, and other relevant words.
