Las ciencias sociales y sus abordajes en los estudios avanzados
Este libro tiene como uno de sus objetivos principales impulsar un ejercicio académico de tipo interdisciplinario entre investigadores y egresados del programa de Doctorado en Ciencias Sociales de la Universidad Autónoma del Estado México (UAEM). Si bien se trata de un esfuerzo incipiente porque los autores que escriben, presentan artículos de investigación en los que desarrollan temas de su campo disciplinar, se trata de un libro relevante porque inaugura una actividad editorial que involucraría a profesores y estudiantes de diferentes líneas de investigación y de distintas disciplinas y les daría la posibilidad de interactuar intelectualmente con el fin de consolidar un diálogo interdisciplinario, que seguramente hará posible desarrollar discusiones de tipo interdisciplinar sobre problemas concretos.Este libro tiene como uno de sus objetivos principales impulsar un ejercicio académico de tipo interdisciplinario entre investigadores y egresados del programa de Doctorado en Ciencias Sociales de la Universidad Autónoma del Estado México (uaem).1 Si bien se trata de un esfuerzo incipiente porque los autores que escriben, presentan artículos de investigación en los que desarrollan temas de su campo disciplinar, se trata de un libro relevante porque inaugura una actividad editorial que involucraría a profesores y estudiantes de diferentes líneas de investigación y de distintas disciplinas y les daría la posibilidad de interactuar intelectualmente con el fin de consolidar un diálogo interdisciplinario,UAE
Gestión del conocimiento. Perspectiva multidisciplinaria. Volumen 7
El libro “Gestión del Conocimiento. Perspectiva Multidisciplinaria”, volumen 7, de la Colección Unión Global, es resultado de investigaciones. Los capítulos del libro, son resultados de investigaciones desarrolladas por sus autores. El libro es una publicación internacional, seriada, continua, arbitrada de acceso abierto a todas las áreas del conocimiento, que cuenta con el esfuerzo de investigadores de varios países del mundo, orientada a contribuir con procesos de gestión del conocimiento científico, tecnológico y humanístico que consoliden la transformación del conocimiento en diferentes escenarios, tanto organizacionales como universitarios, para el desarrollo de habilidades cognitivas del quehacer diario. La gestión del conocimiento es un camino para consolidar una plataforma en las empresas públicas o privadas, entidades educativas, organizaciones no gubernamentales, ya sea generando políticas para todas las jerarquías o un modelo de gestión para la administración, donde es fundamental articular el conocimiento, los trabajadores, directivos, el espacio de trabajo, hacia la creación de ambientes propicios para el desarrollo integral de las instituciones
Genetic, morphological, geographical and ecological approaches reveal phylogenetic relationships in complex groups, an example of recently diverged pinyon pine species (Subsection Cembroides)
Elucidating phylogenetic relationships and species boundaries within complex taxonomic groups is challenging for intrinsic and extrinsic (i.e., technical) reasons. Mexican pinyon pines are a complex group whose phylogenetic relationships and species boundaries have been widely studied but poorly resolved, partly due to intrinsic ecological and evolutionary features such as low morphological and genetic differentiation caused by recent divergence, hybridization and introgression. Extrinsic factors such as limited sampling and difficulty in selecting informative molecular markers have also impeded progress. Some of the Mexican pinyon pines are of conservation concern but others may remain unprotected because the species boundaries have not been established. In this study we combined approaches to resolve the phylogenetic relationships in this complex group and to establish species boundaries in four recently diverged taxa: P. discolor, P. johannis, P. culminicola and P. cembroides. We performed phylogenetic analyses using the chloroplast markers matK and psbA trnH as well as complete and partial chloroplast genomes of species of Subsection Cembroides. Additionally, we performed a phylogeographic analysis combining genetic data (18 chloroplast markers), morphological data and geographical data to define species boundaries in four recently diverged taxa. Ecological divergence was supported by differences in climate among localities for distinct genetic lineages. Whereas the phylogenetic analysis inferred with matK and psbA trnH was unable to resolve the relationships in this complex group, we obtained a resolved phylogeny with the use of the chloroplast genomes. The resolved phylogeny was concordant with a haplotype network obtained using chloroplast markers. In species with potential for recent divergence, hybridization or introgression, nonhierarchical network-based approaches are probably more appropriate to protect against misclassification due to incomplete lineage sorting. The boundaries among genetic lineages were delimited by the inclusion of morphological, geographical and ecological data in the haplotype network. These multiple lines of evidence help to assign species boundaries in this complex group. P. johannis, P. discolor, P. culminicola and P. cembroides are different species based on their genetic, morphological and ecological niche differences. We suggest a reevaluation of the conservation status of these species considering the information generated in this study

“To Assault With The Truth”: The Revitalization of Conservative Militancy in Mexico During the Global Sixties
In-hospital mortality from severe COVID-19 in a tertiary care center in Mexico City; causes of death, risk factors and the impact of hospital saturation.
BackgroundAs the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has remained in Latin America, Mexico has become the third country with the highest death rate worldwide. Data regarding in-hospital mortality and its risk factors, as well as the impact of hospital overcrowding in Latin America has not been thoroughly explored.Methods and findingsIn this prospective cohort study, we enrolled consecutive adult patients hospitalized with severe confirmed COVID-19 pneumonia at a SARS-CoV-2 referral center in Mexico City from February 26th, 2020, to June 5th, 2020. A total of 800 patients were admitted with confirmed diagnosis, mean age was 51.9 ± 13.9 years, 61% were males, 85% were either obese or overweight, 30% had hypertension and 26% type 2 diabetes. From those 800, 559 recovered (69.9%) and 241 died (30.1%). Among survivors, 101 (18%) received invasive mechanical ventilation (IMV) and 458 (82%) were managed outside the intensive care unit (ICU); mortality in the ICU was 49%. From the non-survivors, 45.6% (n = 110) did not receive full support due to lack of ICU bed availability. Within this subgroup the main cause of death was acute respiratory distress syndrome (ARDS) in 95% of the cases, whereas among the non-survivors who received full (n = 105) support the main cause of death was septic shock (45%) followed by ARDS (29%). The main risk factors associated with in-hospital death were male sex (RR 2.05, 95% CI 1.34-3.12), obesity (RR 1.62, 95% CI 1.14-2.32)-in particular morbid obesity (RR 3.38, 95%CI 1.63-7.00)-and oxygen saturation ConclusionsIn this study we found similar in-hospital and ICU mortality, as well as risk factors for mortality, compared to previous reports. However, 45% of the patients who did not survive justified admission to ICU but did not receive IMV / ICU care due to the unavailability of ICU beds. Furthermore, mortality rate over time was mainly due to the availability of ICU beds, indirectly suggesting that overcrowding was one of the main factors that contributed to hospital mortality
Investigaciones en construcción
El Instituto Unidad de Investigaciones Jurídico-Sociales Gerardo Molina, UNIJUS promueve y apoya el desarrollo e implementación de programas y proyectos de investigación que aporten al conocimiento de la realidad nacional e internacional, de las instituciones jurídicas, políticas y sociales, así como de las teorías jurídicas y políticas que contribuyan a la construcción de nuevas propuestas para la solución de las problemáticas que aquejan la sociedad. Por tal motivo, es fundamental el apoyo constante a la formación de semilleros de investigación en la Facultad de Derecho, Ciencias Políticas y Sociales de la Sede Bogotá, así como la consolidación de los semilleros ya existentes. En el año 2012, se desarrollaron las Convocatorias No. 12 y No. 13 para la selección de semilleros de Investigación en modalidad I y modalidad II. Como resultado de dicho proceso fueron seleccionadas doce propuestas de investigación integradas por un total de 32 estudiantes, quienes a su vez se encontraban vinculados a nueve grupos de investigación
