Analysis of the development of themes associated with studies concerning education and covid-19

Education during the pandemic presents itself as a great theme for research between 2020 and 2021. Covid-19 has impacted many people and educational systems have been put to test all over the world. In this regard, several studies, mostly in pre-print, discuss these impacts in relation to a variety of research topics. Therefore, as the pandemic has been a problem affecting education in global proportions, how do the research topics converge in addressing the relationship between education and covid-19 in the major world studies? Getting to know such thematic relations, arising from the scientific research that links education and covid-19, may provide some insights to deal with the educational problems faced in this period. The objective of this study is to describe the themes of high-impact research which associate education with covid-19. For this purpose, data were retrieved from Web of a Science, a centralized database, by means of articles linking education and covid-19 in the field of educational research. These articles have been analyzed by using scientometrics, which created science maps and a thematic network in order to categorize the 607 studies found. Results show the emergence of four categories of topics appearing the articles reviewed: those with consolidated themes, which bring the major topics of the research field;with emerging themes, which present studies raising new topics;of medium dispersion, which seek to specialize the field of knowledge;and the fragmented articles, which show a high dispersion of themes, presenting a myriad of reseach possibilities. © 2022.

A comprehensive analysis of evolution and underlying connections of water research themes in the 21st century.

This work aimed to reflect the advancements in water-related science, technology, and policy and shed light on future research opportunities related to water through a systematic overview of Water Research articles published in the first 21.5 years of the 21st century. Specific bibliometric analyses were performed to i) reveal the temporal and spatial trends of water-related research themes and ii) identify the underlying connections between research topics. The results showed that while top topics including wastewater (treatment), drinking water, adsorption, model, biofilm, and bioremediation remained constantly researched, there were clear shifts in topics over the years, leading to the identification of trending-up and emerging research topics. Compared to the first decade of the 21st century, the second decade not only experienced significant uptrends of disinfection by-products, anaerobic digestion, membrane bioreactor, advanced oxidation processes, and pharmaceuticals but also witnessed the emerging popularity of PFAS, anammox, micropollutants, emerging contaminants, desalination, waste activated sludge, microbial community, forward osmosis, antibiotic resistance genes, resource recovery, and transformation products. On top of the temporal evolution, distinct spatial evolution existed in water-related research topics. Microplastics and Covid-19 causing global concerns were hot topics detected, while metagenomics and machine learning were two technical approaches emerging in recent years. These consistently popular, trending-up and emerging research topics would most likely attract continuous/increasing research input and therefore constitute a major part of the prospective water-related research publications.

A bibliometric review of research on COVID-19 and tourism: Reflections for moving forward.

By adopting a bibliometric analysis approach, this study systematically reviews and retrospectively analyses the rapidly emerging literature on COVID-19 in tourism and hospitality. A co-word analysis revealed the intellectual structure of 177 papers (published until January 2021) consisting of four major themes discussing the following various issues: 1) the impact of COVID-19 on tourist decision-making, destination marketing, technology adoption, and tourists' well-being; 2) the future of tourism post COVID-19; 3) managing change in tourism; and 4) the COVID-19's impacts on tourism and hospitality stakeholders. The findings show that preliminary publications tend to be descriptive, pre-mature and theoretical, i.e. most studies advocate and re-imagine a more sustainable, responsible and equitable post-pandemic tourism, but almost no research investigates in-depth whether, why and how such theoretical proclamations are being materialized or not and/or whether they will remain a COVID-19 induced fuss. The paper concludes by offering various directions and propositions for future research.
