ABSTRACT
This study aimed to outline the profile of retractions of scientific articles on COVID-19 published in journals indexed in the Scopus database between 2020 and 2021. To analyze the data, we used a bibliometric technique, with the Bibliometrix package in the R-Studio software, and descriptive statistics. Twenty-nine retractions were analyzed, and we found that the most common reasons for retraction were related to ethical issues and that 68.97% of authors have previously retracted articles. We concluded that there appears to have been a change in the publication policies of journals, which resulted in an increase in scientific retractions related to COVID-19 during the study period.
ABSTRACT
The main aim of the current article is to compare economic and Quality of Life (QL) indices in G7- (Germany, France, United States, United Kingdom, Japan, Italy and Canada) and BRICS-member countries (Brazil, Russia, India, China and South Africa). The research was developed based on selecting indices available in the NUMBEO, UN (United Nations) and OECD (Organization for Economic Cooperation and Development) databases. Results have evidenced that emerging countries belonging to the BRICS bloc have shown lower QL indices than those observed for developed countries in the G7 bloc. With respect to economic data, the USA, China, Japan and Germany were the countries presenting the highest GDP growth. It was possible concluding that countries belonging to the G7 block have better economic and labor indices, which, in their turn, are associated with better QoL indices.
