Abstract

Background: the formation of adolescents must be comprehensive; in such a way that they achieve a conscious regulation of their behavior, where gender equality becomes relevant.Objective: to design a socio-community strategy to promote gender equality in adolescents, from the work of university extension.Methods: a descriptive study was carried out from January 2021 to March 2022 in the Peoples Council of Calabazar de Sagua, Encrucijada, Villa Clara. Theoretical and empirical methods were used: document analysis, survey of adolescents and interviews with the Integrated Community Work Group, and with people with responsibilities in political and mass organizations in the community. Experts were selected to assess the proposal.Results: the socio-community strategy to promote gender equality for adolescents from the Peoples Council of Calabazar de Sagua used sexist language that projects respect. It had an alternative, participatory and developing character, and promoted changes that guarantee gender equity and equality in the community society at present.Conclusions: the socio-community strategy favors gender equality in adolescents, by emphasizing the need to train them for an equitable social life. It was valued by specialists who recognized its relevance, originality, relevance, coherence and scientific-pedagogical value., Fundamento: la formación de los adolescentes debe ser integral; de forma tal que logren una regulación consciente de su comportamiento, donde cobra relevancia la igualdad de género.Objetivo: diseñar una estrategia sociocomunitaria para favorecer la igualdad de género de los adolescentes, desde la labor de extensión universitaria.Métodos: se realizó un estudio descriptivo entre enero 2021 y marzo 2022 en el Consejo Popular de Calabazar de Sagua, Encrucijada, Villa Clara. Se emplearon métodos teóricos y empíricos: análisis de documentos, encuesta a los adolescentes y entrevista al Grupo de Trabajo Comunitario Integrado, y a personas con responsabilidades en las organizaciones políticas y de masas en la comunidad. Se seleccionaron expertos para la valoración de la propuesta.Resultados: la estrategia sociocomunitaria para favorecer la igualdad de género de los adolescentes del Consejo Popular de Calabazar de Sagua utilizó un lenguaje sexista que proyecta respeto, poseía un carácter alternativo, participativo y desarrollador e impulsó cambios que garantizan la equidad e igualdad de género en la sociedad actual.Conclusiones: la estrategia sociocomunitaria favorece la igualdad de género en los adolescentes, al enfatizar en la necesidad de formarlos para una vida social equitativa.

Abstract

The modern cultivated potato (Solanum tuberosum L.) was first recorded in Europe in the Canary Islands in 1567, but its origin has long been in dispute. Two competing hypotheses have proposed an 'Andean' area (somewhere from the Andean uplands from Venezuela to northern Argentina) or a lowland south-central 'Chilean' area, but the Andean origin hypothesis is today generally accepted. The identity of extant Canary Island potato landraces as exclusively of upland Andean origin is one part of a multicomponent argument that the European potato originated from there, rather than from Chile. We reassess these two competing hypotheses with nuclear microsatellite and chloroplast DNA analyses of 19 Canary Island landraces, 14 Andean landraces, 11 Chilean landraces, and two wild potato species as outgroups, and with chloroplast DNA data of 150 landraces from South America. Our molecular results document a wide variation of Andeanand Chilean-type cultivars on the Canary Islands and possible hybrids of the two. Our new data, integrated with historical, molecular, agronomic, and crossing data, support a hypothesis that there were multiple introductions of Andean and Chilean germplasm to the Canary Islands and that the early European potato was selected from Chilean introductions long before the late blight epiphytotics of the 1840s.

Abstract

Los nuevos servicios y tecnologías surgidos durante los últimos años en Internet plantean serios problemas para los mecanismos de control de congestión y gestión del ancho de banda y otros recursos de la red desarrollados hasta la fecha. Es posible desarrollar nuevos modelos de decisión y operadores de agregación para la gestión de tráfico en redes para escenarios dinámicos (cargas de tráfico variables) contemplando cambios en la topología (agregado y caída de nodos y enlaces) para el siguiente escenario: ** Que los paquetes de datos sean despachados considerando como estado de cada ruta el promedio de los estados de sus nodos. El presente trabajo detalla la forma en que se puede utilizar un nuevo modelo para la toma de decisiones, considerando el entorno de tráfico de paquetes o constitución de circuitos virtuales, aplicando un método de agregación y así generar la secuencia de asignación de las rutas a los paquetes o circuitos virtuales que las solicitan. En base a los cálculos obtenidos se observa que la mejor ruta disponible para el escenario de datagramas resultó ser la que poseía el mayor resultado promedio entre los estados de los nodos, estado de los enlaces y saltos intervinientes de cada ruta posible para el despacho de paquetes The new services and technologies that have emerged in recent years on the Internet pose serious problems for the congestion control mechanisms and management of the bandwidth and other network resources developed to date. It is possible to develop new decision models and aggregation operators for network traffic management for dynamic scenarios (variable traffic loads) contemplating changes in the topology (aggregate and drop of nodes and links) for the following scenario: ** that the data packets be dispatched considering the state of each route as the average of the states of their nodes. the present work details the way in which a new model can be used for decision making, considering the environment of packet traffic or constitution of virtual circuits, applying an aggregation method and thus generating the sequence of allocation of routes to packages or virtual circuits that request them. Based on the calculations obtained, it is observed that the best route available for the datagram scenario turned out to be the one with the highest average result between the states of the nodes, state of the links and intervening jumps of each possible route for the dispatch of packages

Abstract

In the Canary Islands, a number of old Andean potato introductions have been maintained by farmers and are cultivated there since the sixteenth century. Genetic resistance is an inexpensive way to control the main pests and diseases of potato and avoids the use of phytochemicals or other costly protective measures. In this study, we have analysed eight Solanum tuberosum subsp. andigena and S. tuberosum subsp. tuberosum accessions, representing old potato varieties from Tenerife Island, for their resistance levels to Phytophthora infestans, Globodera rostochiensis, Globodera pallida and Pectobacterium atrosepticum. New resistance sources against P. infestans in leaves and P. atrosepticum were found, as well as partial resistance to both nematode species. The results suggest the potential exploitation of the cultivar Venezolana Negra in breeding programmes in order to improve pest and disease resistance of potato. [ABSTRACT FROM AUTHOR]
