Scientometric evaluation of trends and global characteristics of published research on occupational public health

The objective of this scientometric study was to assess the global trends and characteristics of published occupational health research from 2016 to 2020. The SciVal tool (Elsevier) was used to perform the corresponding bibliometric analyses such as the Field-Weighted Citation Impact (FWCI), Source Normalized Impact per Paper (SNIP), CiteScore, and SCImago Journal Rank (SJR). Most of the manuscripts (46.5%) had national collaboration, with an average of 6.1 citations per paper. However, only 71 manuscripts (5.4%) presented single authorship (without collaboration). It was found that 486 manuscripts related to occupational health were published in Q2 journals (top 26-50%). Scientific publications on occupational health have increased remarkably worldwide, especially in Europe, and have mainly been published in Q1 and Q2 journals with a total of 292 and 289 scientific manuscripts in 2019 and 2020, respectively.

The progress and trend of pro-environmental behavior research: a bibliometrics-based visualization analysis

Pro-environmental behavior (PEB) has always been a hot topic in academic and practical, and it is highly necessary to explore the research progress and development trend of PEB. Based on 1038 relevant literatures published and the Web of Science core database, this paper used citation analysis, co-word analysis and cluster analysis methods to systematically analyze the dynamic evolution process of PEB's research topics, knowledge base and subject areas. The results show that PEB research is currently in a period of rapid growth. And PEB research presents typical multidisciplinary characteristics, mainly focuses on Psychology-Education-Social, Economics-Economic-Political, Environmental-Toxicology-Nutrition and other disciplines. Then, this study also finds that the PEB research hotspots mainly concentrated in seven directions such as "Environmental cognition, emotion and motivation process", etc., which can be further classified into three horizontal levels and three vertical levels. This study will provide valuable theoretical and practical reference for the future research of PEB.

A bibliometric analysis of road traffic injury research themes, 1928-2018

Road traffic accidents have become an important social issue worldwide. This study aims to analyse the research status of road traffic injury from 1928 to 2018 and discuss the future research trends. Co-word analysis was applied to analyse 4,184 articles collected from the core collection of Web of Science. Cluster analysis and social network analysis (SNA) were adopted to group keywords, visualize the links between them, and indicate their importance. Strategic diagram was used to reveal the network status of each cluster. The results lead to the following conclusions: (1) 'Road traffic accident', 'injury', 'road safety', 'mortality', and 'risk factor' are at the centre of social network, indicating that these keywords play the most important roles in the field of road traffic injury research. (2) A total of 60 high-frequency keywords are divided into five clusters, namely 'accident causes leading to injury', 'analysis methods', 'health & injury', 'safety management', and 'road traffic', indicating that they are the main sub-fields of road traffic injury research. (3) 'Risk perception' and 'systems theory' are widely discussed topics emerging in recent years. On the basic of the five clusters, valuable references are provided for future research.

Mapping Intellectual Structure and Research Performance for the Nanoparticles in Pancreatic Cancer Field

Objective

To comprehensively analyze the global scientific outputs of nanoparticles in pancreatic cancer research.

Methods

Publications regarding the nanoparticles in pancreatic cancer research published from 1986 to 2019 were retrieved from the Web of Science Core Collection (WoSCC). Highly frequent keywords, publication years, journals, cited papers, cited journals and cited authors were identified using BICOMB software, and then a binary matrix and a co-word matrix were constructed. gCLUTO was used for double clustering of highly frequent journals. Co-citation analysis was performed using CiteSpace V software, including keywords, references, journals author or institution cooperation network.

Results

A total of 1171 publications were included in this study. Publications mainly came from 10 countries, led by the US (n=470) and China (n=349). Among the top 20 journals ranked by the number of citations, nanoscience nanotechnology was the leader with 300. Cluster analysis of citation network identified 12 co-citation clusters, headed by “stromal barrier” and “emerging inorganic nanomaterial”.

Conclusion

Our findings reveal the research performance and intellectual structure of the nanoparticles in pancreatic cancer research, which may help researchers understand the research trends and hotspots in this field.

A Systematic Review on the Research Progress and Evolving Trends of Occupational Health and Safety Management: A Bibliometric Analysis of Mapping Knowledge Domains

Background: Effective occupational health and safety management (OHSM) is important to employee health, enterprise sustainability, and social stability. However, scientific research into OHSM lags behind practice, and contextualizing OHSM research from the perspective of its historical evolution is urgently required.

Methods: The mapping of knowledge domains, based on bibliometric analysis, was adopted to classify 4,852 journal articles related to OHSM listed in the core database of Web of Science and published between 1900 and 2018.

Results and Conclusions: Risk assessment/management at the organizational level were found to have always been research hotspots, and the relationship between safety culture/atmosphere, sickness absence, and safety performance, among other factors, have become core research topics in the field in recent years. Research at the individual level has gradually evolved from an early focus on physiological problems such as work-related musculoskeletal disorders and low back pain, further toward issues such as occupational stress, mental health, and quality of life. In addition, the results of clustering analysis based on high-frequency keywords indicated six aspects of OHSM: OHSM mode and method; OHSM systems and standards; OHS risk assessment and management; OHSM and safety culture; mental health and quality of life; and specific disease management. Future development trends in OHSM research are described providing theoretical and practical reference for further study.

How Much Is Too Much? The Influence of Work Hours on Social Development: An Empirical Analysis for OECD Countries

Work is a cornerstone of social development. Quantifying the impact on development of fluctuations in work hours is important because longer work hours increasingly seem to be the norm. Based on an integrative perspective that combines individual, organizational, and social factors, we constructed a model using data from 31 member countries of the Organisation for Economic Co-operation and Development (OECD). The proposed model was used to test the effect of work hours on different levels and to propose feasible suggestions accordingly. The results show that people in developing countries work more hours per week than those in developed countries, and that males work longer hours than females. Furthermore, regression analysis shows that current work hours are having a negative impact on development in OECD countries, especially in developing countries where people are working longer hours. Longer hours, in other words, do not promote development effectively. Specifically, work hours at the individual level are negatively related to health. At the level of organization, work hours are a reverse indicator of organizational performance, and at the level of society, there is a negative relationship between work hours and economic development. This study provides support for the proposition by the International Labour Organization to reduce work hours, and it facilitates our understanding of the relationship between work hours and social development.

Why Work Overtime? A Systematic Review on the Evolutionary Trend and Influencing Factors of Work Hours in China

Objectives: Research that examined changes in the laws in respect to work hours was of great importance for understanding its current status and causes. However, most research on work hours in China is still conducted using self-reported questionnaires, which lack coherence and depth, and are inadequate for exploring the evolutionary trend of work hours and its mechanism. Methods: This study examined the evolutionary trend of Chinese employees' work hours by employing a cross-temporal meta-analysis, and employed the entropy weight method to analyze each influencing factor. The China National Knowledge Infrastructure (CNKI), VIP information and WanFang database were searched for Chinese-language peer-reviewed literature, and Google Scholar and the Web of Science were searched for related literature in the English language. Results: A total of 36 pieces of literature were identified as having satisfied the quality standards for screening. The results indicated that work hours in China show a significant fluctuating upward trend. Most of the recent studies on work hours in China were cross-provincial investigations, and the issue of overtime among migrant workers has become the key focus of current research. Most studies on the work hours of Chinese employees were conducted in a manner whereby scholars played a leading role while the government assisted. Thus, government-led, intensive and nationwide research needs to be launched. Conclusions: The issue of work hours in China should be taken seriously. The main influencing factors included survival indicators, such as labor market conditions and levels of medical security levels, followed by power-assisted indicators, such as personal income and distribution, while labor protection had a minimal impact. This study will contribute to a better understanding of the essence of work hours among Chinese employees, and will also help to provide a theoretical basis for further intervention study related to overtime work.
