Abstract:
Latin America is one of the regions in which the COVID-19 pandemic has a stronger impact, with more than 72 million reported infections and 1.6 million deaths until June 2022. Since this region is ecologically diverse and is affected by enormous social inequalities, efforts to identify genomic patterns of the circulating SARS-CoV-2 genotypes are necessary for the suitable management of the pandemic. To contribute to the genomic surveillance of the SARS-CoV-2 in Latin America, we extended the number of SARS-CoV-2 genomes available from the region by sequencing and analyzing the viral genome from COVID-19 patients from seven countries (Argentina, Brazil, Costa Rica, Colombia, Mexico, Bolivia, and Peru). Subsequently, we analyzed the genomes circulating mainly during 2021 including records from GISAID database from Latin America. A total of 1,534 genome sequences were generated from seven countries, demonstrating the laboratory and bioinformatics capabilities for genomic surveillance of pathogens that have been developed locally. For Latin America, patterns regarding several variants associated with multiple re-introductions, a relatively low percentage of sequenced samples, as well as an increment in the mutation frequency since the beginning of the pandemic, are in line with worldwide data. Besides, some variants of concern (VOC) and variants of interest (VOI) such as Gamma, Mu and Lambda, and at least 83 other lineages have predominated locally with a country-specific enrichments. This work has contributed to the understanding of the dynamics of the pandemic in Latin America as part of the local and international efforts to achieve timely genomic surveillance of SARS-CoV-2.Keywords:

This note reports on research in Latin America and the Caribbean concerning international relations and foreign policy. It lists persons in the region who are working on these subjects, comments on changing priorities in research by Latin Americans, broadly evaluates the quality of their research, considers the institutional loci and contexts for Latin American work in this field, and discusses the relevance of work in Latin America and the Caribbean to scholars in the United States and other Northern countries, and to those in developing countries beyond Latin America. The report draws on a considerable number of books, journal articles, and unpublished memoranda made available by colleagues, on correspondence with a number of Latin American social scientists, and on several interviews. These notes are surely not complete, and inadvertent inaccuracies may be included, but this version is presented with the hope that it will be helpful to others in its present form and that it may stimulate the submission to LARR of additional pertinent material.

Jorge Sàbato, the Latin American scientist, predicted that ‘either Latin America dominates technology or through other countries technology will dominate Latin America’ (Sagasti 1984). This prediction might serve to point toward one of the objectives to challenge our countries of the Caribbean and Latin America in the coming century. To understand how hard we will have to work to achieve that goal we might look at the barriers to information technology in Latin America and the Caribbean.

Although Latin America is home to 8 percent of the world's population, only 1.7 percent of scholarly knowledge about Latin America is produced there. The limited voice of Latin American scholars in Latin American studies constitutes the loss of a valuable and unique cultural perspective. To address this issue, we interviewed Latin American studies scholars residing in Latin America as well as those residing in the United States and United Kingdom to reveal how and to what extent these scholars participate in the international academic community. Our findings show that the two groups were markedly different. Latin American scholars identify themselves as agents of change, motivated by a desire to solve problems and fulfill social needs in the region, whereas US/UK-based scholars see themselves mainly as experts in the field, driven by a desire to impact the knowledge about the region.

This paper discusses the unique insights that the concept of industry clusters brings to the question of the proper design and implementation of innovation policy in Latin America. It begins by characterizing trends in the use of cluster ideas in development policy making in Latin America, the United States, and Europe. At the end, the paper suggests some guides for policy makers in Latin America and Caribbean region.

In this chapter, we analyze international differences in e-commerce activity and strategies within Latin America and between Latin and non-Latin markets. Starting at a macro-level, we compare e-commerce activity and Internet-related developments in Latin America with developments in other regions. Moving to a closer focus on Latin America, we then discuss the evolution of e-commerce within Latin American countries, with an emphasis on Brazil, Chile, and Mexico. Finally, we identify prevalent business models and analyze the strategies of key players in this sector, and discuss the outlook for the future.
