AbstractIn Descent of Man, Charles Darwin noted the impact of political institutions on natural selection. He thought that institutions such as asylums or hospitals may deter natural selection; however, he did not reach a decisive answer. Questions remain as to whether the selective impacts of political institutions, which in Darwin's terms may be referred to as "artificial selection," are compatible with natural selection, and if so, to what extent. This essay argues that currently there appears to be an essential mismatch between nature and political institutions. Unfitted institutions put exogenous and disproportionate pressures on living beings. This creates consequences for what is postulated as the condition of basic equivalence, which allows species and individuals to enjoy similar chances of survival under natural circumstances. Thus, contrary to Darwin's expectations, it is sustained that assumed natural selection is not discouraged but becomes exacerbated by political institutions. In such conditions, selection becomes primarily artificial and perhaps mainly political, with consequences for species' evolutionary future.

En esta investigación, analicé las bondades que ofrece un aula virtual en el aprendizaje de los estudiantes del bachillerato general. Para la recolección de datos se utilizó encuestas y entrevistas, para lo cual realicé una entrevista a los directivos del colegio, encuesté a 10 docentes, además a 112 estudiantes, teniendo como resultado una mejora en el aprendizaje. Esta investigación propone analizar el impacto del aula virtual en el proceso de aprendizaje en los estudiantes del bachillerato general, para el diseño del entorno virtual de aprendizaje basado en la plataforma Moodle. Analizando los resultados, se establece que, el estudiante debe hacer uso del aula virtual para adquirir nuevos conocimientos para aumentar su rendimiento académico, debido a que esta herramienta tecnológica ayuda a realizar trabajos autónomos enviados por los docentes para complementar las tareas diarias. Utilizamos la plataforma Moodle para el diseño del aula virtual, la cual permite: Distribuir información, intercambiar ideas, experiencias, aplicar, experimentar lo aprendido, evaluar los conocimientos, además, mantener tanto la seguridad como confiabilidad en el Sistema. También se concluye que haciendo uso del aula virtual el estudiante podrá construir su propio conocimiento teniendo como base conocimientos previos, esto gracias al uso sencillo de la tecnología y aplicaciones informáticas.

One of the most profound demographic changes in the United States over the past several decades is the redistribution of immigrants from Latin America to new destinations. However, little attention has been paid to differences in homeownership by national origin and destination type among this population. This is surprising because homeownership is a most significant investment and component of wealth for most residents. Using the American Community Survey to examine the likelihood of owning a home among immigrants from Mexico, El Salvador, and Guatemala, the main objective of this research was to investigate how homeownership among the three immigrant groups intersects with destination type. The results indicate that these immigrants have significantly lower rates of homeownership in new destinations than in established settlement areas after controlling for a host of individual and metropolitan‐level characteristics. At the same time, the role of destination is not the same for all groups. Guatemalans have the lowest levels of homeownership overall, but Mexican immigrants are the least likely to own a home in new destinations. These findings are further explored and discussed.
