Reconstrucción Del Discurso Pedagógico Desde El Saber Como Expresión Del Orden Establecido

El discurso docente evidencia debilidades en cuanto al uso adecuado de competencias comunicativas que desde lo pragmático, cognoscitivo, lingüístico y tecnológico contribuyan a la consolidación del aprendizaje significativo. Por tanto, el referido estudio tiene como propósito generar un modelo teórico del discurso pedagógico desde el saber como expresión del poder impuesto y del orden establecido por la sociedad para la implementación de competencias comunicativas de tipo oral y escrito en la universidad. Teóricamente, estará sustentado en la Semiótica de Saussure, la Acción Comunicativa de Habermas y el Análisis del Discurso de Van Dijk. Bajo el enfoque interpretativo, la naturaleza se inscribe en el paradigma cualitativo, nivel descriptivo, con modalidad de campo, pues los datos se tomarán desde el escenario donde interactúan los sujetos informantes, quienes serán seis docentes de tres universidades en Venezuela. La vía metodal será la Teoría Fundamentada, siendo la inducción la ruta para la construcción de conocimiento

A molecular surveillance-guided vector control response to concurrent dengue and West Nile virus outbreaks in a COVID-19 hotspot of Florida

Simultaneous dengue virus (DENV) and West Nile virus (WNV) outbreaks in Florida, USA, in 2020 resulted in 71 dengue virus serotype 1 and 86 WNV human cases. We hypothesized that we would find a number of DENV-1 positive mosquito pools, and that the distribution of these arbovirus-positive mosquito pools would be associated with those neighborhoods for which imported DENV cases have been recently reported in 2019 and 2020. We collected and screened Aedes aegypti, Ae. albopictus, Anopheles crucians, Culex coronator, Cx. nigripalpus, and Cx. quinquefasciatus mosquitoes from Miami-Dade County (Florida) for DENV and WNV by rRT-qPCR. Spatial statistical analyses were performed to capture positive mosquito pool distribution in relation to land use, human demography, environmental variables, mosquito trap placement and reported human travel associated DENV cases to guide future mosquito control outbreak responses. A rapid screen of 7,668 mosquitoes detected four DENV serotype 2 (DENV-2), nine DENV-4 and nine WNV-positive mosquito pools, which enabled swift and targeted abatement of trap sites by mosquito control. As expected, DENV-positive pools were in urban areas; however, we found WNV-positive mosquito pools in agricultural and recreational areas with no historical reports of WNV transmission. These findings demonstrate the importance of proactive arbovirus surveillance in mosquito populations to prevent and control outbreaks, particularly when other illnesses (e.g., COVID-19), which present with similar symptoms, are circulating concurrently. Growing evidence for substantial infection prevalence of dengue in mosquitoes in the absence of local index cases suggests a higher level of dengue endemicity in Florida than previously thought.

A molecular surveillance-guided vector control response to concurrent dengue and West Nile virus outbreaks in a COVID-19 hotspot of Florida

Abstract Simultaneous dengue virus (DENV) and West Nile virus (WNV) outbreaks in Florida, USA, in 2020 resulted in 71 dengue virus serotype 1 and 86 WNV human cases. Our outbreak response leveraged a molecular diagnostic screen of mosquito populations for DENV and WNV in Miami-Dade County to quickly employ targeted mosquito abatement efforts. We detected DENV serotypes 2 and 4 in mosquito pools, highlighting the silent circulation of diverse dengue serotypes in mosquitoes. Additionally, we found WNV-positive mosquito pools in areas with no historical reports of WNV transmission. These findings demonstrate the importance of proactive, strategic arbovirus surveillance in mosquito populations to prevent and control outbreaks, particularly when other illnesses (e.g., COVID-19), which present with similar symptoms are circulating concurrently. Growing evidence for substantial infection prevalence of dengue in competent mosquito vectors in the absence of local index cases suggests a higher level of dengue endemicity in Florida than previously thought. Article Summary Line Evidence of increasing dengue endemicity in Florida: Vector surveillance during dengue and West Nile virus outbreaks revealed widespread presence of other dengue virus serotypes in the absence of local index cases
