En el año 2020, la enfermedad originada por el virus SARS-CoV-2, denominada “COVID-19”, ocasionó un distanciamiento social en casi la totalidad de los países del mundo. Dicho aislamiento trajo consecuencias en los distintos sectores de la sociedad, entre ellos el educativo, donde la enseñanza y aprendizaje migraron a entornos virtuales. En México, el cierre masivo de escuelas se dio a partir del segundo trimestre del 2020, sin que el sistema educativo estuviera del todo preparado para la transición a la virtualidad, lo que generó una serie de problemáticas bajo esta nueva modalidad educativa. La presente obra aborda algunas de las problemáticas que se presentaron en los distintos niveles de nuestro sistema educativo mexicano a partir de las experiencias y reflexiones de profesores e investigadores tras dos años de pandemia, lo cual nos permite ofrecer un acercamiento a la nueva realidad educativa de nuestro país y, a al mismo tiempo, nos proporciona herramientas útiles ante los desafíos que se avecinan en la etapa DOI: https://doi.org/10.52501/cc.069

Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Juan Carlos Tedesco, a prominent Argentinean sociologist argues that qualitative studies of education in Latin America represent a major challenge to current research. Latin American qualitative researchers are producing interpretive studies that focus on the realities of current developmental and educational reforms. Indigenous communities, women, students, and teachers are given voice in these studies, which represent the state of Latin American ethnographic, qualitative, and participatory research. This is the first book in English to offer a state-of-the-art collection of educational qualitative research studies in Latin America. The first three chapters present an overview of qualitative research, while the remaining seven chapters provide studies that explore various aspects of education from public schools to informal educational programs.
