Characteristics and Trends of Ocean Remote Sensing Research from 1990 to 2020: A Bibliometric Network Analysis and Its Implications (full-text)

The ocean is of great significance in the climate system, global resources and strategic decision making. With the continuous improvement in remote sensing technology, ocean remote sensing research has increasingly become an important topic for resource development and environmental protection. This paper uses bibliometric analysis method and VOSviewer visual software to conduct analysis. The analysis focuses on the period from 1990 to 2020. The analysis results show that articles have been steadily increasing over the past two decades. Scholars and researchers form the United States, China and Europe (mainly Western European countries), as well as NASA, Chinese Academy of Sciences and NOAA have bigger influence in this field to some extent. Among them, the United States and NASA holds the core leading position. Moreover, global cooperation in this field presents certain characteristics of geographical distribution. This study also reveals journals that include the most publications and subject categories that are highly relevant to related fields. Cluster analysis shows that remote sensing, ocean color, MODIS (or Moderate Resolution Imaging Spectroradiometer), chlorophy, sea ice and climate change are main research hotspots. In addition, in the context of climate warming, researchers have improved monitoring technology for remote sensing to warn and protect ocean ecosystems in hotspots (the Arctic and Antarctica). The valuable results obtained from this study will help academic professionals keep informed of the latest developments and identify future research directions in the field related to ocean remote sensing.

Social life cycle assessment: mapping scientific knowledge

Social life cycle assessment (sLCA) is a methodology to support decision making on social impacts, positive and negative, actual or potential, related to product life cycles [1,2]. Being a relatively new tool, the indicators are not yet homogenized and the method does not have a standard to be followed nor a code of practice [3] [4]. Therefore, describing the state-of-the-art scientific research into sLCA is necessary to clarify the current situation and to determine future development goals [5]. The aim of this paper is, to describe the scientific trends related to sLCA through a bibliometric and a network analysis. This will enable us to identify the main collaborations and help to standardize the sLCA methodology.

Methodology: The research process consists of four steps. 1, define the search query. 2, retrieve data. 461 articles from the Scopus database and 348 from the WOS database were obtained and exported. 3, clean up the refined database. Using Vantage Point (VP) text mining software, the obtained data were cleaned up, applying fuzzy logic algorithms to clean up the data fields. 4, generate the sLCA scientific profile and the network analysis. This scientific profile will define the publication trends and academic performance, and the network analysis will allow us to determine the main collaboration relationships.

Conclusions: sLCA, as a methodology for measuring the social impacts of companies, is gaining prominence. More and more is being published on sLCA, especially since 2018. The countries doing the most research on the subject are European, with Germany leading by far, followed by Italy. Nonetheless, the United States, Canada, China and Brazil are also among the top researchers. In terms of scientific collaborations, the same countries appear as the main collaborators, although the United States ranks first as an intermediary country. The institutions that contribute the most scientific production on sLCA are mainly European universities of technology. These universities have a closed pat- tern of scientific collaboration on sLCA, i.e. they form research clusters that collaborate little with other clusters. The same is true for the main authors; research is also carried out in closed clusters. In addition, the European Union is the main economic driver of this research topic. Finally, the most frequently used keywords in the publications are those related to life cycle, assessment and sustainability.

Research Trends on Pillared Interlayered Clays (PILCs) Used as Catalysts in Environmental and Chemical Processes: Bibliometric Analysis (full-text)

Over the last four decades, a large number of studies have been published on pillared interlayered clays (PILCs) used as adsorbent materials and catalysts or supports for transition metals in heterogeneous catalysis. Particularly, PILCs have been used for water treatment through advanced oxidation processes (AOPs) to remove organic pollutants. They have also been studied in various chemical and environmental processes. Because of the growing interest in PILCs, this article is focused on analyzing scientific publications such as research/review articles and book chapters from the last four decades (from 1980 to 2019) through a bibliometric analysis (BA) to visualize and describe research trends on PILCs. By narrowing the bibliographic search to titles, keywords, and abstracts of publications related to PILCs, using Scopus and Web of Science (WoS) (the two scientific databases), a total of 3425 documents have been retrieved. The bibliometric dataset was analyzed by VantagePoint®. The main research trends identified in the last four decades were the use of PILCs in environmental processes (34.4% of total publications) along with chemical processes (petrochemical reactions 17.5%, SCR NOx 10.8%, and decomposition 8.2%). In environmental processes, PILCs have been used in photo-oxidation (32%), CWPO (21.1%), and heterogeneous catalysis (19.4%). Phenols, dyes, and VOCs have been the main pollutants studied using PILCs as catalysts. Fe, Ti, Zr, Cu, and Co are the most supported active phases in PILCs. Other research trends grouped by characterization techniques, countries, research areas, institutes, scientific journals that have published the most on this topic, number of publications per 5-year period, and most frequently used keywords through the last four decades have been identified. It was determined that the number of publications on PILCs has increased since 1980 and the countries with the highest number of publications are China, Spain, and The United States of America.

A postcolonial feminist exploration of the scholarship on women and educational leadership with a bibliometric approach

This study applied a bibliometric approach to a dataset of publications on women and educational leadership to critically explore the nature of research in the field and the utility of the bibliometric method in its mapping. The analysis was conducted on bibliographic records of 823 papers on women and educational leadership published from 1975 to 2020, which had been retrieved from the Web of Science. The results are presented in the form of lists of most impactful papers; most productive research centres/organizations and countries; similar lists of contributing disciplines and publication venues; as well as maps visualizing collaborative activity. A postcolonial feminist perspective used in interpretation of the results reveals that, on the one hand, the approach makes it possible to uncover the persistent coloniality and linguistic hegemony in the field, whereas, on the other hand, bibliometric metrification may contribute to Western epistemic violence and valorisation of scholarship in masculinist terms.

Two-decade bibliometric overview of publications in the Journal of Knowledge Management

The purpose of this paper is to accomplish a bibliometric analysis, investigate the underlying knowledge structure, founding and development, and evolution of the Journal of Knowledge Management (JKM) through its articles published between 1997 and 2020. A total of 1,346 research papers from JKM were selected and VantagePoint® software was used to generate bubble maps, auto-correlation maps, and matrix maps through techniques such as principal component analysis (PCA) and natural language processing (NLP). The analysis gives insights about the foundation of knowledge structure, its evolution and the development of JKM. The systematic mapping of research illustrates topics emerging as new offshoots, global favourites, saturated and plateaued and reached academic maturity. The USA, the UK, Australia, Spain, Italy, China, Canada, Germany, and France have contributed the most to JKM. This paper provides a robust roadmap for future research investigation of JKM. The authors humbly admit the possibility of overlooking some research papers while evaluating and filtering the database of JKM. The research outcome summarizes 23 years, subject to information retrieval from archival files.This research is a detailed bibliometric analysis explaining paradigm shifts in the body of knowledge of JKM. The bibliometric outcomes can act as beacons for future researchers and academicians to revisit the current trends that shape the domain of knowledge management, particularly for the JKM audience with a focus on contemporary topics of research interest. This is a unique endeavour to accomplish a systematic bibliometric analysis of the JKM for two decades, offering insights about its structural body of knowledge through an overview of the chronology of scholarly development in the field of knowledge management.

Worldwide trends on molar incisor and deciduous molar hypomineralisation research: a bibliometric analysis over a 19-year period

The goal of this study was to identify the worldwide trends in scientific evidence and gaps in knowledge regarding molar incisor hypomineralisation (MIH) and deciduous molar hypomineralisation/hypomineralised second primary molars (DMH/HSPM), exploring the contribution of authors and countries, possible etiological factors and proposed treatments, in order to guide future research in the area. Searches were conducted in MEDLINE, Scopus, Web of Science, Cochrane Library, Lilacs/BBO, Embase and Google Scholar. Studies employing the terms MIH, DMH/HSPM and their linguistic variations were included. The following data were extracted: title, authors, year and journal of publication and first author’s affiliation country. Studies were categorized according to topic, dentition, study design, etiological factors and types of treatments. Categories were analysed in relation to their distribution, co-occurrence, cross-correlation and/or autocorrelation. Results Five hundred and three studies were included. The most published authors were Manton D (n = 47), de Souza JF (n = 22) and Ghanim A (n = 22) and four main collaboration clusters have been identified. Most of the studies were conducted on permanent dentition (MIH) (87.4%); with observational design (57.2%). The “European Archives of Paediatric Dentistry” was the most published journal (13.3%) and a significant increase in the number of publications was observed in the last decade. MIH was most studied in relation to prevalence/incidence, systemic factors involved in its aetiology and treatment with composite restorations, while a gap in knowledge was observed for extraction and sealants. Less studies were published on DMH/HSPM and most of them evaluated risk factors or prevalence/incidence. The gap of knowledge was observed in relation to treatments and patient’s quality of life. This bibliometric review provided a comprehensive overview of research in MIH and DMH/HSPM over the past 19 years. Within the limitations of the present study, the following conclusions can be drawn: global trends point to an increasing peak of scientific publication, especially in the last decade, while there is a shortage of clinical studies on treatments, mainly evaluating tooth extractions. Finally the multifactorial nature should be further explored, considering environmental and systemic factors together.

Impact of teacher education abroad in international co-authorship: a study of Federal University of São Carlos’s scientifics production indexed in the Web of Science (FULL-TEXT)

Metric studies on internationalization, especially indicators of co-authorship, present challenges regarding the collection, representativeness, and reliability of the data measuring the impacts of international mobility. Aiming to contribute to the understanding of scientific collaboration initiatives, the present research’s objective was to investigate the relationship between outside teacher education, represented by the completion of a doctoral degree and post-doctoral internship, and international collaboration, identified by the international co-authorships in institutional scientific output. The research method was the exploratory case study, and the case unit was the Federal University of São Carlos. The Lattes Platform and the Web of Science were used as sources of information, and the sample analyzed comprised 12,787 scientific articles and 1,915 Lattes resumés. It was found that 1,850 teachers have doctoral or post-doctoral education (96.6%) and, of these, 632 graduated abroad (33.1%). Regarding the scientific output, 3,487 of the 12,787 articles were published in international co-authorship (27.3%). From the scientific output in international co-authorship, indicators on the groups of teachers with and without education abroad were analyzed. Among the indicators developed, 8.43 articles per teacher were identified for the group with education abroad, while in the group without education abroad, 4.26 articles were identified per teacher. The results demonstrate a positive relationship between doctoral or post-doctoral education abroad with international co-authorships, contributing to institutional internationalization. for FULL-TEXT
