Populismo, obediencia y divergencia
, 2018 ES: El presenta artículo aborda desde una visión amplia los supuestos teóricos, filosóficos y sociológicos, de la obediencia a la ley penal, en particular, en sociedades injustas y desiguales en las que los gobiernos carecen de legitimidad para imponer los deberes a los ciudadanos, con el fin de resolver los dilemas que emergen en ese escenario.

Divergencias de la serie armónica
Educación matemática, 1999 En este artículo presentamos un acercamiento elemental a la divergencia a infinito de la serie armónica, así como a su comportamiento asintótico, el cual está relacionado con la función logaritmo natural y la famosa constante g de Euler. La representación gráfica de las sumas parciales de la serie, la cual obtuvimos con Mathematica, no solamente es un ...

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa
New Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Policy Studies Journal, Volume 54, Issue 2, May 2026.ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.We provide the first reliable hypothesis on the phylogenetic position of Calisto and Llorenteana within the tribe Satyrini, based on genomic data representing all subtribes. We apply for the first time nucleotide mixture models, which overcame the inconsistencies resulting from the use of partitioned models in this and previous studies, obtaining a ...

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning
Functional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

EURE (Santiago) - Revista Latinoamericana de Estudios Urbano Regionales, 2004 La globalización, con sus efectos diferenciadores por países, regiones y grupos sociales, vuelve a animar el debate sobre la hipótesis de convergencia, a la base de la teoría neoclásica del crecimiento.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.

Una aplicación del análisis espacial al estudio de las diferencias regionales del ingreso en México
Economía, Sociedad y Territorio, 2003 Con base en tres técnicas estadísticas diferentes, este trabajo confirma una tendencia de convergencia económica entre 1970 y 1980 y de divergencia económica entre 1970 y 1990.
