Identifying trends, patterns, and collaborations in nursing career research: A bibliometric snapshot (1980–2017)

Trends and hot topics in nurse empowerment research: A bibliometric analysis

AIM

The characteristics of the publications on nursing empowerment should be investigated in order to get an idea about the development of the field and to determine the developments in nursing practices and research. This study aimed to investigate the characteristics of the current knowledge structure and developmental process in nurse empowerment by using bibliometric methods.

METHODS

The data of this retrospective descriptive study were obtained from the Web of Science (WoS). All relevant studies conducted before 2020 were included in the study. The data analysis was conducted with Excel, SPSS and VOSviewer.

RESULTS

Five hundred eighty-nine studies conducted between 1974-2019 were included in the study. It was found that 72.15% of these studies were journal articles and these studies were conducted by 1,450 authors. The studies were published in 109 journals and were produced by researchers from 49 different countries. Also 47.5% of these studies were conducted in the United States. Hot topics were "empowerment", "nursing," "structural empowerment," "nurses," "job satisfaction" and "psychological empowerment."

CONCLUSION

There has been a noteworthy increase in the number of studies on nurse empowerment and this field offers an active field of study for nursing researchers. The focus of the studies varies from nurses to nurse managers.

Microalgae-Derived Pigments: A 10-Year Bibliometric Review and Industry and Market Trend Analysis

Microalgae productive chains are gaining importance as sustainable alternatives to obtain natural pigments. This work presents a review on the most promising pigments and microalgal sources by gathering trends from a 10-year bibliometric survey, a patents search, and an industrial and market analysis built from available market reports, projects and companies' webpages. The performed analysis pointed out chlorophylls, phycocyanin, astaxanthin, and β-carotene as the most relevant pigments, and Chlorella vulgaris, Spirulina platensis, Haematococcus pluvialis, and Dunaliella salina, respectively, as the most studied sources. Haematococcus is referred in the highest number of patents, corroborating a high technological interest in this microalga. The biorefinery concept, investment in projects and companies related to microalgae cultivation and/or pigment extraction is increasingly growing, particularly, for phycocyanin from Spirulina platensis. These pieces of evidence are a step forward to consolidate the microalgal pigments market, which is expected to grow in the coming years, increasing the prospects of replacing synthetic pigments by natural counterparts.
