This article selects literature on employee voice behavior from the China Knowledge Network (CNKI) and some journals from Web of Science between 2000 and 2024. Using the knowledge graph technology tool CiteSpace, a bibliometric analysis is conducted. The article reviews and comments on the annual publication volume, keyword co-occurrence, keyword clustering, keyword time zone changes, and keyword emergence in the literature on employee voice behavior. It compares the differences in research methods between domestic and international studies, summarizes the causes and consequences of employee voice behavior, and identifies the frontiers and hotspots in this field. Based on existing research, an integrated model of employee voice behavior is proposed from four aspects: independent variables, mediating variables, moderating variables, and behavioral consequences. The article also looks forward to future research on employee voice behavior in terms of the influence of situational factors, the evolution of the oppositional relationship between voice behavior and silence behavior, and the outcomes of the behavior.展开更多

The causal link between NETs and sepsis progression has been extensively validated. However, few articles have utilized bibliometric methods to analyze research in this field. Therefore, this paper analyzes the research hotspots and trends in NETs and sepsis over the past two decades from a bibliometric perspective, aiming to provide new insights into the fundamentals and research in this field. Methods: We collected publications related to neutrophil extracellular traps (NETs) in the field of sepsis from 2004 to 2024 from the Web of Science Core Collection. Publications were limited to articles and reviews, and the language was restricted to English. VOSviewer and COOC software were used to conduct bibliometric and knowledge map analysis of research collaboration networks, journals, cited references, and keywords in this field. Results: From 2004 to 2024, the Web of Science Core Collection included 720 articles on NETs and sepsis research, including 452 articles and 226 reviews. Since 2022, the number of articles in this field has rapidly increased. The United States and China are the primary contributors in this field. Articles on this topic have been published in 294 academic journals. The author with the most publications is Liaw Patricia C., and Frontiers in Immunology is the most cited journal. In addition to “sepsis” and “neutrophil extracellular traps,” high-frequency terms in the keyword co-occurrence network analysis include inflammation, neutrophils, platelets, thrombosis, Covid-19, infection, innate immunity, and septic shock. An analysis of keyword trends using the burst test indicates that thrombosis and ARDS are currently at the forefront of research in this field. ARDS is currently a hot topic regarding the related roles and potential mechanisms of NETs and sepsis in this field. Conclusion: This study provides a bibliometric analysis and visualization of key research areas in sepsis and NETs over the past 20 years. The results indicate that thrombosis and ARDS are currently hot topics regarding the related roles and potential mechanisms of NETs and sepsis in this field.展开更多

A total of 19 cities covering 16 provinces were selected with 1, 610 dwellings measured for indoor radon concentration. The arithmetic mean and geometric mean of indoor radon concentration were 68 Bq m-3 and 57 Bq m-3,respectively. It was found that indoor radon concentrations were much higher in the Severe Cold Area than those in the Cold Area.The indoor radon concentrations showed an increasing trend for newly constructed buildings.展开更多
