Este trabajo de grado tuvo como propósitos, establecer las problemáticas del profesorado novel universitario en su desarrollo profesional y determinar las perspectivas de aprendizaje en su desarrollo profesional. El enfoque de la investigación es el cualitativo, con la intención de comprender e interpretar el significado de las narrativas del profesorado novel conforme nueve cuestiones que se plantearon con anticipación y en los que gira el presente estudio. En el proceso investigativo, se emplearon tres fases con sus respectivas etapas: a) Preparatoria (Reflexiva y de diseño), b) De campo (Acceso, recopilación y análisis de datos) y c) informe final (Difusión de resultados). Se empleó como técnica la entrevista que fue dirigida a 68 docentes noveles provenientes de todas las Facultades de la Universidad Central del Ecuador. Para la interpretación de los datos, se empleó una matriz de codificación; precisando, categorías, códigos y subcódigos para cada cuestión de investigación. Para el análisis y procesamiento de los datos obtenidos, se utilizó el programa informático Aquad Seis a fin de interpretar los códigos sociodemográficos e inferenciales a la luz del marco conceptual generado. Consecutivamente, se confrontaron los hallazgos encontrados con otros estudios a fin de discutir sus coincidencias y diferencias para su comprensión. Posteriormente, se establecieron conclusiones generales respecto, a: problemáticas en sus funciones básicas, influencia de las relaciones con autoridades y compañeros para el desarrollo profesional, oportunidades de participación y responsabilidades, percepción sobre sus procesos de capacitación, necesidades para su formación profesional, decisiones de las autoridades institucionales para fortalecer el desarrollo profesional y perspectivas de aprendizaje para el desarrollo profesional del profesorado novel. Seguidamente, se propusieron dos alternativas para solucionar la problemática investigada y finalmente; se crearon, tres implicaciones con la finalidad de reflexionar y rediseñar los procesos empleados para el desarrollo profesional del profesorado novel universitario.

COVID-19 is rarely reported in children and they are mildly affected in most cases. The most common clinical presentation of COVID-19 is cough, fever and sore throat; severe cases show tachypnea. The course of the disease is from one to two weeks. Laboratory findings are nonspecific; lymphopenia, elevation of C-reactive protein and procalcitonin have been described. Early chest X-ray is usually normal, and the most common tomographic findings are consolidations with halo, ground-glass opacities and tiny nodules which mainly affects subpleural areas. Management of the disease is supportive; in severe cases, it should be focused on respiratory support. It is recommended to limit the handling of respiratory secretions and to follow the same preventive measures provided to adults. / Revisión por pares

Microorganisms are widespread in all ecosystems and play critical roles in nature. They are major players in global biogeochemical cycles that are fundamental in nutrient cycling. Molecular ecology surveys that investigate the microbial diversity of many different environments have revealed an impressive diversity of microbes in nature and have highlighted our inability to cultivate the vast majority of them in the laboratory. The improvement of our ability to grow uncultivable microbes in laboratory conditions will help us in this challenging task. Standard cultivation methods that have helped to bring to culture many relevant microorganisms in the past century are, however, characterized by limitations which hamper the isolation of novel microbes. For this reason, alternative cultivation strategies have been developed in recent decades which have allowed to expand the collection of environmentally relevant but poorly represented microbial strains. The use of such novel approaches for investigating the microbial diversity of underexplored natural ecosystems, such as sub-tropical mangrove forests, can result in the isolation, in laboratory conditions, of bacterial strains belonging to previously undescribed taxa. Mangroves are unique environments exposed to strong selection forces with respect to other marine environments, including high temperatures, salinity and oligotrophy. I hypothesize that these unique combinations of environmental features have selected microbiomes with unique characteristics. The aim of this PhD research is to explore the bacterial diversity of the Red Sea mangrove ecosystem, by applying an alternative cultivation strategy that uses oligotrophic conditions and long incubation time. I also exploited the diffusion chamber to cultivate bacterial taxa belonging to rarely isolated or even novel genera. This approach allowed me to isolate four novel bacterial taxa. Using 16S rRNA gene sequencing, the isolated bacteria were identified as one novel species and three novel genera belonging to Alpha-proteobacteria, Bacteroidetes, and Firmicutes, respectively. These isolates were further characterized and described through genomic, phylogenetic, chemotaxonomic, and phenotypic analysis to describe their ecological significance in the ecosystem of origin (i.e., mangrove sediments). This study reveals that the extreme conditions of the Red Sea mangroves have selected a unique and yet mostly untapped culturable microbiome with great potential for environmental applications.

WE SEE THINGS WITH OUR EYES AND WE WANT THEM is a novel is stories following a female narrator, Janine, through adolescence and adulthood. Whether inspired by a spark of sexual tension over snack cakes, a broken down purple ‘96 Saturn named Lydia, a child’s pool party, or an ill-advised journey through a hospital air-vent system, Janine finds herself obsessed with trying to understand those she loves, and attempts to share the deeper parts of herself in the process.
