    Model-Driven Web Engineering methodologies provide a more productive way of building Web Applications using high-level models and generating final implementations from them. However, they follow a waterfall-like development process, forcing to specify a different set of models sequentially to obtain a first runnable prototype of the Web Application. On the other hand, agile methodologies pursue an iterative process based on the delivery of application prototypes in short periods of time using manual coding, which results less productive and more error-prone in comparison to model-based approaches. In this work we propose a hybrid agile and Model-Driven approach called MockupDD that intends to blend the best of MDWE and agile development processes.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 8295).Laboratorio de Investigación y Formación en Informática Avanzad

    Challenges for the Adoption of Model-Driven Web Engineering Approaches in Industry

    Get PDF
    Model-driven web engineering approaches have become an attractive research and technology solution for Web application development. However, after 20 years of development, they have attracted little attention from the Industry due to the mismatch between technical versus research requirements. In this joint work between academia and industry, the authors present the current problems of using these approaches in scale and provide guidelines to convert them into viable industry solutions.Ministerio de ciencia e Innovación TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED

    Progressive transfusion and growth factor independence with adjuvant sertraline in low risk myelodysplastic syndrome treated with an erythropoiesis stimulating agent and granulocyte-colony stimulating factor

    AbstractRefractoriness to growth factor therapy is commonly associated with inferior outcome in patients with low-risk myelodysplastic syndrome (LR-MDS) who require treatment for cytopenias. However, the mechanisms leading to refractoriness are unknown. Here we describe a clinically depressed 74-year-old male with refractory cytopenia with multilineage dysplasia (RCMD) and documented growth factor refractory anemia after erythropoeisis stimulating agent (ESA) therapy, who attained transfusion and growth factor independence after the addition of sertraline to his medication regimen. Our case demonstrates hematological improvement-erythroid (HI-E) in growth factor refractory, low risk MDS and highlights a potential mechanistic link between common inflammatory diseases and LR-MDS

    Vidas vulneráveis: Ser migrante em tempos de conservadorismo e crise pandêmica na América Latina

    Get PDF
    A América Latina, bem como outros espaços geopolíticos, tem experimen- tado, um brusco giro conservador na última década. Em diferentes escalas, gover- nos de direita e de extrema-direita, atrelados às lideranças religiosas, políticas e intelectuais conservadoras, substituíram governos de centro e centro-esquerda. Junto com essa recente onda, presenciamos também, após um breve intervalo de ordem progressista, o ressurgimento da agenda neoliberal, que atuou forte- mente, logo após o fim dos regimes ditatoriais na região, e adentrou a década de 1990. Nesse cenário político e econômico, assistimos, ainda, o brotar, com maior protagonismo, de um forte discurso nacionalista conservador. Por meio de práticas radicais, exaltam o ciclo das ditaduras militares, a restrição das liberdades de expressão e organização e combatem o reconhecimento político de minorias sociais, bem como a presença de migrantes em suas mais distintas classificações jurídicas. Acompanhamos, através de estudos e manchetes, populações migra- tórias sendo indiscriminadamente responsabilizadas pelas inseguranças sociais e econômicas vividas nos territórios nacionais e, sobretudo, em zonas de fronteira. Em diversos países, foram registradas formas de xenofobia social e estatal sofri- das por certas categorias de migrantes. Os exemplos, como serão apresentados ao longo deste dossiê, são inúmeros3. Medo, insegurança, confusão, exclusão e precariedade são exacerbados na existência desses migrantes. Soma-se a isso o espalhamento da COVID-19 por toda a região e o duro impacto que ela trouxe para as zonas de fronteira. Um dos principais usos políticos da pandemia tem sido o de aprofundar um intenso sentimento de suspeita do estrangeiro como aquele responsável por trazer o vírus e, por conseguinte, a morte. Em tempos de pandemia, a suspeita exacerba-se como também o medo de que esses corpos alheios sejam vetores de contágio. Variadas fobias, durante a pandemia, impac- tam de diferentes maneiras a população em condição de mobilidade humana nas América.Fil: Dias, Gustavo.

    25 Years of Model-Driven Web Engineering : What we achieved, what is missing

    Get PDF
    Model-Driven Web Engineering (MDWE) approaches aim to improve the Web applications development process by focusing on modeling instead of coding, and deriving the running application by transformations from conceptual models to code. The emergence of the Interaction Flow Modeling Language (IFML) has been an important milestone in the evolution of Web modeling languages, indicating not only the maturity of the field but also a final convergence of languages. In this paper we explain the evolution of modeling and design approaches since the early years (the 90’s) detailing the forces which drove that evolution and discussing the strengths and weaknesses of some of those approaches. A brief presentation of IFML is accompanied with a thorough analysis of the most important achievements of the MDWE community as well as the problems and obstacles that hinder the dissemination of model-driven techniques in the Web engineering field.Laboratorio de Investigación y Formación en Informática Avanzada (LIFIA

Departamento de Ingeniería Electrónica; Argentina.In order to predict long-term series, a Bayesian enhanced approach (BEA) combining permutation entropy (BEMA) is presented. The motivation of the proposed filter is to predict long-term time series by changing the structure of the predictor filter according to data model selected, then computational results are evaluated on high roughness time series selected from benchmark, in which they are compared with recent artificial neural networks (ANN) nonlinear filters such as Bayesian Enhanced approach (BEA) and Bayesian Approach (BA). These results support the applicability of permutation entropy in analyzing the dynamic behavior of chaotic time series for long-term series predictions.http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7585299&isnumber=7585232Fil: Rodriguez Rivero, Cristian.

    From requirements to web applications in an agile model-driven approach

    Get PDF
    Web applications are hard to build not only because of technical reasons but also because they involve many different kinds of stakeholders. Involving customers in the development process is a must, not only while eliciting requirements but also considering that requirements change fast and they must be validated continuously. However, while model-driven approaches represent a step forward to reduce development time and work at a higher level of abstraction, most of them practically ignore stakeholders' involvement. Agile approaches tend to solve this problem, though they generally focus on programming rather than modeling. In this paper we present an extension to an approach that combines the best of both worlds, allowing a formal and high-level design style with constant involvement of customers, mainly in the definition of navigation, interaction and interface features. We extended it by adding transformation features that allow mapping requirement models into content and navigation ones. We provide a proof of concept in the context of the WebML design method and an empiric validation of the approach's advantages.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 7387).Facultad de InformáticaLaboratorio de Investigación y Formación en Informática Avanzad
