¿Hambre cero?: diagnóstico, perspectivas y desafíos
Get PDFSe presenta un diagnóstico que revela las dificultades identificadas en 2019 para lograr las metas sustantivas para el cumplimiento del Objetivo de Desarrollo Sostenible Hambre Cero en 2030, propuesto por la Asamblea General de las Naciones Unidas en septiembre de 2015, en la denominada Agenda 2030. Esta constatación, observada en todo el mundo, se agudiza por el impacto económico actual producido por la pandemia del Covid-19, y las perspectivas que se avizoran son inciertas y además desalentadoras. América Latina y el Caribe, y particularmente Argentina, disponen de alimentos suficientes para toda su población. Sin embargo, es el acceso a los alimentos y no la disponibilidad el problema fundamental a resolver. El complejo científico-tecnológico tiene un lugar relevante en el objetivo de hacer realidad el derecho a la alimentación. Por un lado, realizando aportes metodológicos a las metas instrumentales presentes en dicho objetivo. Por otro lado, asegurando que el conocimiento científico y técnico en torno de las mismas impacte, a través de las políticas públicas, en la población en situación de vulnerabilidad social y económica.A diagnosis is presented that reveals the difficulties identified in 2019 to achieve the substantive goals for the fulfillment of the Sustainable Development Goal Zero Hunger in 2030, proposed by the United Nations General Assembly in September 2015, in the so-called Agenda 2030 This confirmation, observed all around the world, is exacerbated by the current economic impact produced by the Covid-19 pandemic, and the prospects foreseeing that are uncertain as much as discouraging. Latin America and the Caribbean, and particularly Argentina, have enough food for their entire population. However, food availability is not the main problem but access to it. The scientific-technological field has a relevant place for the purpose of making the right to food a reality. On the one hand, making methodological contributions to the instrumental goals present in the purpose mentioned. On the other hand, ensuring that the scientific and technical knowledge around them impact, through public policies, on populations in vulnerable situations.Apresentaremos um diagnóstico que revela as dificuldades identificadas em 2019 para atingir as metas significativas para o cumprimento da Meta de Desenvolvimento Sustentável Fome Zero em 2030, proposta pela Assembleia Geral das Nações Unidas em Setembro de 2015, na chamada Agenda 2030. Essa constatação, observada em todo o mundo, é exacerbada pelo atual impacto econômico produzido pela pandemia de Covid-19. Diante do cenário, as perspectivas que surgem são incertas e, além do mais, não promissoras. A América Latina e o Caribe, e particularmente a Argentina, têm alimentos suficientes para toda a sua população. Porém, é o acesso aos alimentos e não a disponibilidade que é o problema fundamental a ser resolvido. O complexo científico-tecnológico ocupa um lugar relevante no objetivo de tornar o direito à alimentação uma realidade; tanto trazendo contribuições metodológicas para os objetivos instrumentais presentes nesse objetivo quanto garantindo que o conhecimento científico e técnico ao seu redor impactem, por meio de políticas públicas, a população em situação de vulnerabilidade social e econômica
UX-Painter: An Approach to Explore Interaction Fixes in the Browser
Get PDFUsability and user interaction improvement is a central task in web development to guarantee the success of a web application. However, designers are barely able to keep up with the current development cycle because their practices are too costly, while interaction issues accumulate in applications that end-users keep suffering. In this work, we propose a method for designers to rapidly explore solutions through visual programming to the interaction problems of an application under development, even when it has been already deployed. The method is realized by a tool called UX-Painter, an exploratory tool for designers to apply quick fixes to interaction issues at the client-side of a web application without the need of any script programming knowledge. The palette of available fixes in UX-Painter are client-side web refactorings, i.e., changes to web page elements that solve specific user interaction problems without changing the underlying functionality. UX-Painter allows designers to quickly set up new versions of a web application by combining refactorings to create alternative designs for user testing or an inspection review. UX-Painter also provides the means to communicate design improvements, as a sequence of refactorings with clear semantics. We show the feedback provided by interviews with designers about UX-Painter’s functionality and the results of a user test about its usability

A practical tool for selecting microalgal species for biodiesel production
Get PDFIn the search for energy sources to replace fossil fuels, microalgae have shown promising characteristics. Their cultures have several advantages over the conventional crops used for commercial biodiesel: they have fast growth rates and a high lipid content and can grow in environments unfit for agriculture. However, relatively few species have so far been studied as biodiesel feedstock. In order to facilitate the search for potentially useful species/strains, in this work, a bioprospecting tool based on biomass and oil production process requirements, triacylglyceride content, and biodiesel properties has been developed. For this purpose, an overall score (OS) was proposed as a tool based on biological, economic, and environmental factors. By applying the OS to nine species, we were able to narrow down the number of species within the diatom group, which are potentially suitable for large-scale biodiesel production. Halamphora coffeaeformis, Navicula cincta, and N. gregaria were the species with the highest OS (1.65-1.5). It is expected that this tool will provide a useful contribution to the criteria applied in the selection of microalgal species for large-scale biodiesel production
Relevamiento sobre condiciones y medio ambiente de trabajo en contexto de ASPO en la UNLP
Get PDFEn el marco del Aislamiento Social Preventivo y Obligatorio (ASPO), la Asociación de Docentes Universitarios de La Plata (ADULP), realizó un relevamiento acerca de las condiciones en las que las y los docentes de la UNLP están llevando adelante sus tareas. El objetivo fue describir el estado del trabajo docente en el contexto actual, identificar situaciones de vulneración de derechos, y visibilizar desigualdades.
La encuesta estuvo dirigida a los docentes de todas las dependencias de la UNLP, abarcando tanto el sistema de grado y posgrado como de pregrado. El instrumento de recolección que se utilizó fue un cuestionario web autoadministrado y anónimo que contenía 69 preguntas distribuidas en 10 bloques. El cuestionario se mantuvo habilitado para ser respondido desde el 27 de Mayo hasta el 8 de junio de 2020, cuando ya se contaba con más de 80 días de aislamiento social y prácticamente la misma cantidad de tiempo de actividades académicas de manera virtual en muchas de las dependencias de la UNLP.
Entre los principales temas que se indagaron se encuentran: características generales de las y los docentes y de sus cargos y funciones, situación actual respecto de la materia que dictan, recursos disponibles para sostener las actividades de manera virtual, conocimientos y capacitación sobre soportes digitales y herramientas virtuales, tiempo destinado a las tareas docentes, consecuencias y efectos del aislamiento y de la virtualización del trabajo. Lxs docentes debieron contestar varios de estos puntos sólo en relación al cargo con mayor dedicación horaria. Si bien esta decisión metodológica permitió estandarizar muchas de las respuestas y relacionarlas con otras variables, no fue posible relevar qué ocurría en los cargos de menor dedicación de aquellxs trabajadorxs con más de un cargo docente. Se recibieron 1.620 respuestas, 1.439 de docentes de grado y posgrado, y 181 de docentes de pregrado. Salvo en los casos donde esté aclarado, los gráficos del informe expresan la información agregada de ambos sistemas
Tendencies in multi-agent systems: a systematic literature review
No full textThe application of Artificial Intelligence mechanisms allows the development of systems capable to solve very complex engineering problems. Multi-agent systems (MAS) are one paradigm that allows an alternative way to design distributed control systems. While research in this area grew exponentially before 2009, there is a need to understand the status quo of the field from 2009 to June 2017. An extension of the results of a SLR related to Multi-Agent Systems, its applications and research gaps, following Kitchenham and Wholin guidelines are presented in this paper. From the analysis of 279 papers (out of 3522 candidates), our findings suggest that: a) there were 20 gaps related to agent-oriented methodologies; coordination, cooperation and negotiation; modelling, developing, testing and debugging; b) 24 gaps related to specific domains (recycling, dynamic evacuation, hazard management, health-care, industry, logistics and manufacturing, machine learning, ambient assisted living); and 14 gaps related to specific areas within MAS (A-Teams, dynamic MAS and mobile agents, ABMS, evolutionary MAS, and self-organizing MAS). These gaps specify lines of research where the MAS community must work to achieve the unification of the agent-oriented paradigm; as well as strengthen ties with the industry
Tool support for Generating User Acceptance Tests
Get PDFSoftware testing, in particular acceptance testing, is a very important step in the development process of any application since it represents a way of matching the users’ expectations with the finished product´s capabilities. Typically considered as a cumbersome activity, many efforts have been made to alleviate the burden of writing tests by, for instance, trying to generate them automatically. However, testing still remains a largely neglected step. In this paper we propose taking advantage of existing requirement artifacts to semi-automatically generate acceptance tests. This paper extends a previous paper in which we use Scenarios, a requirement artifact used to describe business processes and requirements, and Task/Method models, a modelling approach taken from the Artificial Intelligence field. The proposed approach derives a Task/Method model from Scenario (through rules) and from the Task/Method model specification, all alternatives in the flow of execution are provided. Using the proposed ideas, we show how the semi-automated generation of acceptance tests can be implemented by describing an ongoing development of a proof of concept web application designed to support the full process
La incorporación de la mirada histórica al campo de la salud: ¿reconstrucción del pasado o discusión del presente?
No full textLa organización de una convocatoria sobre “Historia y salud” en la revista Salud Colectiva tiene como propósito aportar al desarrollo de una mirada histórica de los procesos de salud-enfermedad. En este sentido, nos interesa rescatar la mirada de las ciencias sociales y de la historia para poner en relieve que tanto la definición de las condiciones de salud como la posibilidad de acceso a servicios sanitarios esenciales por parte de la población, lejos de ser el reflejo de ciertas condiciones biomédicas objetivas, son el resultado de un proceso social en el que se ponen en juego saberes, ideologías, políticas e intereses de distinto tipo. Esto implica, en primer lugar, que la propia definición de qué problemas de salud de la población deben atenderse es el resultado de las relaciones –no exentas de conflicto– entre los distintos actores involucrados. Y, en segundo lugar, que la distribución desigual de recursos económicos, simbólicos y culturales implica un acceso diferencial a los servicios de salud, tanto para los individuos como para los grupos sociales
Potamolithus spp. in the Argentine Pampas
No full textThe genus Potamolithus is the only native representative of the family Tateidae in South America. Six species of Potamolithus have been recorded from Buenos Aires province, on the Argentinean coasts of the Río de la Plata. These coasts are used for different purposes which could affect species of Potamolithus; however, the actual impact of these threats is unknown. The objective of this project is to know the conservation status of the genus Potamolithus in the Pampean region along the coast of the Río de la Plata. For this, seasonal sampling is being carried out at sites with historical records, providing the first population studies (growth and recruitment) of species in this genus and completing anatomical and molecular descriptions. The Argentinean coast of the Río de la Plata has been greatly altered by people and the invasion of Limnoperna fortunei in recent years, which has made it difficult to find specimens of Potamolithus. On IMG, specimens have been observed at various sites, and growth experiments are being carried out both in situ and in the laboratory. Because of the conchological, anatomical, and genetic analyses, five taxonomic entities are distinguished
Professores em tempos de pandemia
No full textNeste trabalho, são apresentadas brevemente três experiências de professores universitários que, no âmbito do isolamento social preventivo e obrigatório imposto pela pandemia do COVID-19, como o restante do ensino argentino, tivemos que “mudar” nossas práticas e nosso conhecimento de a modalidade presencial para uma plataforma digital. Na primeira parte, relacionamos nossas experiências no cenário atual e descrevemos as situações vivenciadas e as incertezas que às vezes nos acompanham. Nos voltamos para o conceito de conhecimento da profissão de professor para analisar nossa experiência e interpretar nossas decisões atuais. As narrativas expõem eixos analíticos que enfatizam o conceito de conhecimento da profissão docente: tempo e espaço, emoções e intelecto, doação e significado compartilhado.In this work, three experiences of university professors are briefly presented that, in the context of the preventive and obligatory social isolation imposed by the COVID-19 pandemic, like the rest of Argentine teaching, we had to “change” our practices and our knowledge of the face-to-face modality to a digital platform. In the first part, we relate our experiences in the current scenario and describe the situations experienced and the uncertainty that sometimes accompanies us. We turn to the concept of knowledge of the teaching profession to analyze our experience and interpret our current decisions. The narrations expose analytical axes that stress the concept of knowledge of the teaching profession: time and space, emotions and intellect, donation, and shared meaning.En este trabajo se presentan brevemente tres experiencias de profesoras universitarias que en el marco del aislamiento social preventivo y obligatorio impuesto por la pandemia del COVID-19, al igual que el resto de la docencia argentina, debimos “mudar” nuestras prácticas y nuestros saberes de la modalidad presencial a una plataforma digital. En la primera parte, relatamos nuestras experiencias docentes en el escenario actual y describimos las situaciones vividas y la incertidumbre que por momentos nos acompaña. Acudimos al concepto saberes del oficio de enseñar para analizar nuestra experiencia e interpretar nuestras decisiones actuales. Las narraciones exponen ejes analíticos que tensionan el concepto saberes del oficio de enseñar: tiempo y espacio, emociones e intelecto, donación y sentido compartido
