Especificación de Componentes MDA para Patrones de Diseño

The Model Driven Architecture (MDA) promotes the use of models and model transformations for developing software systems. The idea behind MDA is to manage the evolution from Platform Independent Models to Platform Specific Models that can be used to generate executable components and applications. The concepts of metamodels and metamodel-based model transformations are critical in MDA. In this paper, we analyze how to specify reusable components for design patterns in a way that fit MDA very closely. To define families of reusable components we describe a “megamodel” that refers to metamodels and model transformations organized into an architectural framework. We propose an integration of formal and semiformal specifications to specify MDA mega-components. Our formalization focuses on interoperability of formal languages in Model Driven Development (MDD).La Arquitectura Model Driven (MDA) promueve el uso de modelos y transformaciones de modelos para desarrollar sistemas de software. La idea central de MDA es manejar la evolución de modelos independientes de la plataforma a modelos específicos a la plataforma que pueden ser usados para generar componentes ejecutables y aplicaciones. En el contexto MDA los metamodelos y las transformaciones basadas en metamodelos son esenciales. En este artículo describimos como especificar componentes para patrones de diseño alineados a MDA. Para definir familias de componentes reusables presentamos un “megamodelo” que integra metamodelos y refinamientos organizados en un framework arquitectural. Proponemos integrar especificaciones semiformales y formales para especificar mega-componentes MDA. Nuestra formalización se centra en la interoperabilidad de lenguajes formales en el desarrollo Model Driven (MDD)

Unraveling the origin of the cultivar ‘Bonarda’ in Argentina using microsatellite molecular markers

‘Bonarda’ es una variedad de vid que en Argentina se cultiva principalmente en las provincias de Mendoza y San Juan, representa el segundo cepaje tinto en superficie nacional cultivada y es considerada con gran potencial para la elaboración de vinos tintos de alta calidad. Existe incertidumbre respecto a su origen en el país. La descripción ampelográfica de la ‘Bonarda’ cultivada en Argentina remarca gran nivel de similitud con la variedad italiana ‘Bonarda Piemontesa’ y con la variedad francesa ‘Corbeau’. En un trabajo previo, basado en el uso de marcadores moleculares, se demostró que ‘Bonarda’ se diferencia de ‘Bonarda Piamontesa’ y es idéntica a ‘Corbeau’. El objetivo de este trabajo fue confirmar la identidad de esta variedad empleando un gran número de loci microsatélites de tal manera de cubrir -en lo posible- la mayor parte del genoma. Se analizaron 17 accesiones de ‘Bonardas’ procedentes de distintos puntos geográficos de las provincias de Mendoza y San Juan, y de la variedad francesa ‘Corbeau’. Para las reacciones de PCR se usaron 13 loci microsatélites. Todas las accesiones de ‘Bonarda’ fueron idénticas entre sí e idénticas a la variedad francesa Corbeau, por lo que se concluye que se trata de la misma variedad. Se propone que la variedad ‘Bonarda’ cultivada en Mendoza y San Juan sea denominada ‘Bonarda-Argentina’, para diferenciarla de las italianas, pero a sabiendas, con un alto nivel de confianza, que corresponde a la variedad noble francesa ‘Corbeau’.'Bonarda' is the second most cultivated red variety in Argentina, mainly in the provinces of Mendoza and San Juan. In the past few years it has been valued for its great potential for the production of high quality wines. The origin of this variety was uncertain. The ampelographic description of the Argentine 'Bonarda' shows high level of similarity to the Italian variety 'Bonarda Piemontese,' and the French variety 'Corbeau'. However, recent work using molecular markers has shown that 'Bonarda' differs from ‘Bonarda Piedmontese’ and is identical to 'Corbeau'. The aim of this study was to confirm the identity of this variety using a larger number of microsatellite loci in such a way to cover, if possible, the entire genome. We analyzed 17 accessions of 'Bonarda' from the provinces of Mendoza and San Juan, Argentina, and the French variety 'Corbeau' with 13 microsatellite loci. All accessions of 'Bonarda' were identical to each other and to the French variety ‘Corbeau’, confirming that it is the same variety. It is proposed that the variety 'Bonarda' grown in Mendoza and San Juan is called 'Bonarda from Argentina' to distinguish it from the Italian Bonarda, but knowing, with a high confidence level, that corresponds to the noble French variety 'Corbeau'.Fil: De Rosas, María Inés.

Resisting neoliberalism in social work education: learning, teaching, and performing human rights and social justice in England and Spain

In an increasingly complex, globalized world, many of the problems confronting social workers are rooted in structural inequalities created or deepened by uncontrolled neoliberal market mechanisms. Yet neoliberal political agendas dominating the global order encourage individualistic models of social work intervention, characterized by managerialism and deprofessionalization. Critiquing the impact of neoliberalism, those aligned with critical and radical social work traditions have highlighted the use of narrow technicist interventions to disguise the root social causes of people´s suffering and contradicting values of human rights (HR) and social justice (SJ) that lie at the heart of social work as a profession. For social work students to locate themselves confidently within HR and SJ frameworks, they must experience HR and SJ as central to their education. This article draws on doctoral research exploring how HR and SJ are operationalized in social work education in England and Spain. A web survey of social work educators and students was complemented by interviews with educators in both countries. Findings revealed key opportunities for learning, teaching and performing HR and SJ in social work education. We discuss each in turn, reflecting briefly on the implications for enhancing the profile of HR and SJ in social work education

Influence Pattern Effectiveness

Los superiores utilizan diferentes tácticas de influencia para conseguir que los subordinados realicen las actividades encomendadas. Para comprender la dinámica existente en este proceso de influencia es importante considerar la combinación de diversas tácticas y no sólo el estudio separado de cada una de ellas. El presente estudio ha analizado la efectividad de los patrones de influencia empleados por los superiores jerárquicos con sus empleados. Se han identificado cuatro patrones de influencia empleados por los superiores: patrón fuerte, patrón racional, patrón activo y patrón pasivo. Su efectividad se ha analizado en términos de satisfacción, compromiso y bienestar de los empleados. Los superiores que recurren a una mayor combinación de tácticas de influencia resultan más efectivos que aquellos que utilizan una única categoría de tácticas. Se analizan las implicaciones del estudio para la práctica directiva.Influence pattern effectiveness. Managers apply different influence tactics to get subordinates to perform their tasks. For a better understanding of the influence process dynamics, it has been recommended to consider the combination of different tactics instead of analyzing them separately. (Cialdini & Goldstein, 2004). The present study has analyzed the effectiveness of various influence tactics combinations used by superiors with their subordinates. We identified four influence patterns: hard pattern, rational pattern, active pattern and passive pattern. Pattern effectiveness was analyzed in terms of subordinates’ satisfaction, commitment and well-being. We found that superiors who used a broader range of tactics were more effective than those using a single range of tactics. Practical implications are discussed

Listening to the Voices of Novice Lecturers in Higher Education: A Qualitative Study

The professional development of novice staff at the university still requires considerable improvement. In this research paper, and in an attempt to define a development model in higher education, attention is paid to the perspectives and judgments of novice university staff. The research focuses specifically on the expression of their problems, difficulties, dilemmas, and decisions related to their course plans and classroom contexts. The methodology applied here integrates processes of qualitative interpretation supported by the AQUAD Six data processing program in the presentation of results. These findings make clear the need to integrate novices into the teaching community in order to reduce the fears they experience on starting their academic careers and increase the benefits to the university community as a whole

Recovering Sequence Diagrams from Object-oriented Code

Software modernization is a current research area in the software industry intended to transform an existing software system to a new one satisfying new demands. The initiative Architecture-Driven Modernization (ADM) helps software developers in tackling reverse engineering, software evolution and, software modernization in general. To support modernization problems, the ADM Task Force has defined a set of metamodels such as KDM (Knowledge Discovery Metamodel), being the Eclipse-MDT MoDisco project the official support for software modernization. We propose the application of ADM principles to provide relevant model-based views on legacy systems. We describe a framework to reverse engineering models from object-oriented code. In this context, we show how to recover UML sequence diagrams from Java code. We validate our approach by using ADM standards and MoDisco platform. Our research can be considered a contribution to the MoDisco community; MoDisco does not support reverse engineering of sequence diagrams and, on the other hand, the MoDisco KDM Discover was used and enriched to obtain the required information for recovering interaction diagrams

Modeling, diagnosis, and control of fuel-cell-based technologies and their integration in smart grids and automotive systems

Society is gradually becoming aware that the current energy system based on the use of fossil fuels is inefficient, highly polluting, and finite supply. Within the scientific community and industry stakeholders, there is a unified agreement that indicates that hydrogen (H2), as an energy vector, combined with other sources of alternative energy, represents a safe and viable option to mitigate the problems associated with hydrocarbon combustion because the entire system can be developed as an efficient, clean, and sustainable energy source. In this context, the change from the current energy system to a new system with a stronger involvement of H2 relentlessly involves the introduction of fuel cells as elements of efficient energy conversion.Peer Reviewe
