Profiling the Research Landscape on Cognitive Aging: A Bibliometric Analysis and Network Visualization.

Objectives: This study aimed to profile the cognitive aging research landscape from 1956 to 2021.

Methods: A total of 3,779 documents were retrieved from the Scopus database for the bibliometric analysis and network visualization. By comparing each keyword's overall connection strength (centrality), frequency (density), and average year of publication (novelty) to the calculated median values acquired from the overlay view of the VOSviewer map, the enhanced strategic diagrams (ESDs) were constructed.

Flipped classroom in the second decade of the Millenia: a Bibliometrics analysis with Lotka's law.

This paper aims to examine the current dynamics of the flipped classroom studies and to propose a direction for future research for the field. Using a bibliometric approach, we observe a sample of 1557 documents from the Scopus database to identify research activity on the flipped classroom. The keywords "flipped classroom" and "flipped learning" have been executed in the search query.

Worldwide melatonin research: a bibliometric analysis of the published literature between 2015 and 2019.
