This is a homage to Loet Leydesdorff, teacher and scientific reference. Through the combination of overlay maps, a visualization technique proposed by himself and Ismael Ràfols, in combination with the CAMEOs (Characterizations Automatically Made and Edited Online) proposed by Howard White, we project his scientific trajectory in five different scenarios, which turn out to be complementary.

Agricultural Sciences have become one of Brazil’s most efficient and sustainable research areas, where most publications benefit from scientific collaboration. The present study analyzes the influence of the designation as the corresponding author to researchers linked to Brazilian institutions on the impact of co-authored articles in the category Agronomy from the Web of Science for five-year periods from 2005 to 2019. We have observed a noticeable growth in the number of documents in collaboration between the five-year periods.

Abstract: Authorship is associated with scientific capital and prestige, and corresponding authorship is used in evaluation as a proxy for scientific status. However, there are no empirical analyses on the validity of the corresponding authorship metadata in bibliometric databases.

This study aims to identify and compare the national scope of research at the country level, dealing with two groups of countries: Latin America and the Caribbean (LAC) and a group of countries at the forefront in developing mainstream science (WORLD). We wish to explore whether similar or different patterns arise between the two groups at the global and disciplinary level, becoming apparent in their proportion of research related to local perspectives or topics. It is found that Latin America and the Caribbean countries present a greater proportion of local production.

Frontiers in Research Metrics and Analytics (FRMA) was launched in 2016 as an open-access journal to provide a forum for learning, evaluating, and improving research and scholarship in a wide range of disciplines. FRMA aims to provide a stimulating and inspirational forum not only for scholars devoted to advancing theories and instruments of how research should be done and how it can be done efficiently but also for researchers to apply and integrate available conceptual frameworks and enabling technologies in their own practice of research.

Abstract. The COVID-19 pandemic brought the issue of immigrant irregularity to the public fore, exposing undocumented migrants’ vulnerabilities and the reliance of supply chains on their ‘essential work’. While pro-regularisation instances emerged in several countries, governments responded differently to them. Delving into the political determinants of immigrant regularisation programmes, the article compares the cases of Italy and Spain, traditionally considered as ‘hallmarks’ of the ‘Southern European immigration model’.
