Uma abordagem baseada em aspectos e composição dinâmica para a construção de aplicações adaptativas cientes ao contexto

Ubiquitous computing systems operate in environments where the available resources significantly change during the system operation, thus requiring adaptive and context aware mechanisms to sense changes in the environment and adapt to new execution contexts. Motivated by this requirement, a framework for developing and executing adaptive context aware applications is proposed. The PACCA framework employs aspect-oriented techniques to modularize the adaptive behavior and to keep apart the application logic from this behavior. PACCA uses abstract aspect concept to provide flexibility by addition of new adaptive concerns that extend the abstract aspect. Furthermore, PACCA has a default aspect model that considers habitual adaptive concerns in ubiquitous applications. It exploits the synergy between aspect-orientation and dynamic composition to achieve context-aware adaptation, guided by predefined policies and aim to allow software modules on demand load making possible better use of mobile devices and yours limited resources. A Development Process for the ubiquitous applications conception is also proposed and presents a set of activities that guide adaptive context-aware developer. Finally, a quantitative study evaluates the approach based on aspects and dynamic composition for the construction of ubiquitous applications based in metrics

GingaForAll: linha de Produtos do Middleware Ginga

Many challenges have been imposed on the middleware to support applications for digital TV because of the heterogeneity and resource constraints of execution platforms. In this scenario, the middleware must be highly configurable so that it can be customized to meet the requirements of applications and underlying platforms. This work aims to present the GingaForAll, a software product line developed for the Ginga - the middleware of the Brazilian Digital TV (SBTVD). GingaForAll adds the concepts of software product line, aspect orientation and model-driven development to allow: (i) the specification of the common characteristics and variables of the middleware, (ii) the modularization of crosscutting concerns - both mandatory and concepts variables - through aspects, (iii) the expression of concepts as a set of models that increase the level of abstraction and enables management of various software artifacts in terms of configurable models. This work presents the architecture of the software product line that implements such a tool and architecture that supports automatic customization of middleware. The work also presents a tool that implements the process of generating products GingaForAll

A igreja católica e as novas comunidades: do cosmos ao caos moderno

La discussion des métamorphoses de l'Église Catholique Romaine causés par ses relations avec la modernité est la toile de fond au débat sur l'émergence de nouveaux mouvements religieux, en particulier les nouvelles communautés. Dans le but de comprendre la convergence/ divergence ou conservation/ changement en ce qui concerne la relation entre l'Institution et la Communauté, j'ai choisi de contextualiser l'histoire du christianisme catholique dans la modernité et dans la post-modernité à partir de penseurs classiques et contemporains. J ai évité une vision unilatérale qui met l'accent sur l'aspect objectif ou subjectif et a opté pour une approche dialogique capable de permettre une lecture des deux côtés de la réalité. Cette réflexion a guidé le travail ethnographique réalisé dans deux communautés à Cidade do Natal: Fraternité Éfeso et Communauté Catholique Veni Creator Spiritus. Cette recherche a montré que les nouvelles communautés promeuvent un nouveau catholicisme certainement plus conservateur que réformateur; tantôt elles attirent et rettiennent les croyants dans l'Église, tantôt inquiètent la hiérarchie ecclésiastique - depuis l encadrement de ce nouveau phénomène dans la structure existante jusqu'à sa orientation

Prática do acolhimento à pessoa idosa na atenção básica: uma estratégia de humanização

The aging of the population already is a fact, before considered a phenomenon, today, is part of the reality of the majority of the societies in the world. The present study it has as objective to analyze the practical one of the shelter developed for the team to multidiscipline for the elderly in the Strategy of Health of the Family. One is about a descriptive and exploratória inquiry, developed by means of quantitative boarding. The population of this study consisted of nineteen teams that work in the inserted ESF in the urban zone of the city of Sousa-PB, understanding a complete of 133 professionals. The collection of date was carried through through a questionnaire contends closed questions, referring to the partner-demographic date e, specific open questions. The main results indicate that the professionals of Health of the city of Sousa, PB, that had participated of this study had consisted in a complete of 76. Amongst these, 20% are nurses, followed of the odontólogos in 6%; 35% are ACS and technician of nursing with 19%. The age of the interviewed ones meets in the age band enters, 21 and 30 years, in 43%. The majority is of the feminine sex with a 84% total. Already in accordance with civil state 34% is married. If treating to the wage, the doctor has of greater of 12 wages. The participants present the percentile greater of formed time of with referring 33% of 1 the 3 years of formation. E finally, the changeable time of performance, if had detached 39% of the participants with 08 the 11 years. With regard to as if it processes the reception and attendance to the person in the ESF, we can observe that, with priority attendance was prominence with 27% of the participants, followed of a considerate attendance with 26%. Already in relation to the actions that are developed daily in the ESF, these they are come back toward the HIPERDIA with 40%, followed of actions ruled in orientation with 27%. Some actions they are carried through in accordance with the aged necessity of each (13%) and through visits domiciliary (9%). It was asked to them as the shelter was facilitated in the UBS, these had told that it is through the attention that is excused the aged one (35%), and finally, as this made it difficult age, in its majority with 37% they had not wanted to answer, followed of the lack of understanding with 26%. With this study it was possible to conclude that the practical one developed for the professionals of the ESF of the city of Sousa, PB with the elderly, is characterized by an assistance ruled in the clinical aspect, little focused in the actions that to permeate the PNH

O gênero crônica na sala de aula do ensino médio

In this work we present the results of a research that aims to study the chronicle gender produced in a class of native language. The texts were written by students of a high-school class, under the orientation of the teacher who conducted a didactic sequence in order to explore this gender. In our analysis we observed aspect such as the structure of the general structure of the texts, types of speech and linguistic sequences, some mechanisms of textualization and the characteristics of the gender. In order to attain that, we adopted the theoretical presuppositions of Textual Linguistics and of the Socio-discursive Interactionism, grounding the study of texts and gender in Bronckart (2003; 2006) and Koch (2002; 2004). As a background of the Chronicle Gender we used the studies of Coutinho (1987); Moisés (2003); Sá (2005); Bender; Laurito (1993); Melo (1994); Cândido et al. (1992) among others. The corpus, made up of 15 texts, showed that the narrative is the most used linguistic sequence in the producing of the texts, the discursive world prevailing in the narrative and some instances of the world of exposing. As for the gender characteristics, the daily life was used in order to amuse the reader and make him to reflect upon the daily life. Humor, irony, social criticism and colloquial language were also observed in the texts produced by the students. Although some texts presented the characteristics of the gender, explored in the classroom, some were typically school narratives. That make us believe that a work with textual production under the approach of a text gender is viable, but it is not consolidated yet in many schools as the main object of the central teaching of the Portuguese language. This make us defend a better systematization of the teaching contents having as the main point the reading practice and text production in order to contribute for the growing of the students´ discursive potentialities and, therefore, their effective participation in the language social practices

Análise textual dos discursos: responsabilidade enunciativa no texto jurídico

This investigation aims at describing, analyzing and interpreting the Commitment in Initial Petitions, which is a genre circumscribed in the judicial domain. For this purpose, we have chosen sections, facts as found and relevant law , sections of the petition, with the understanding that, in this way, respectively, the narration of events, which gives margin to the propositioning to the judicial action, and the exposition of the law that upholds the author s intention. We base our discussion on the field of Linguistics, more precisely, Textual Discourse Analysis (TDA), whose theoretical basis is derived from Textual Linguistics (TL) and Enunciative Linguistics. We foreground, particularly, the way in which the author of texts, objects of analysis, use discursive strategies that evidence ER. The relevance of this study, then, is in the formation of a critique of the judicial text, as it conceives of a dialogical approach to the point of view, raising not only questions about the way in which a linguistic instance conceives an object of discourse, but also considering questions of language inherent to technical writing and, in this aspect, contributing to the work of those operating in Law about the many ways ER is formed in the body of a petition. We selected two categories to analyze that, according to Adam (2011), characterize the degree of ER in the textual material of the propositional enunciations: the different types of representation of speech and the indications of profile of mediators. In this sense, with this task as an objective, we base our study regarding point of view on Rabatel (2003, 2009a, 2010) with relation to the enunciative approach, including the study of PDV in polyphonic and dialogical theoretical framework to study the ER from different types of speech representations that conceive forms of transmission of discourse and the role of the enunciating subject, mainly the responsibility and the prerogative by the propositional contents. In the same way, intending to study the indications of the mediator profiles, we observed the postulations of Guentchéva (1994, 1996), which develop the notion of mediative grammatical categories, of which permit the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. The methodology we adopted was based on qualitative research, of an interpretive and introspective nature, in light of the fact that his study focuses on processes and strategies underlying language use. The corpus of the research is comprised of Initial Petitions, which gave rise to actions originating in the Civil Court of Currais Novos County RN. The data analysis shows that an object of discourse is always perspective oriented and presents the point of view of one or more enunciators. Consequently, the producer of a text, using the PDV of other enunciators, influences and establishes the argumentative orientation of the text. In the same way, it evidences the relevance of the use of mediated constructions in the judicial text, as they function as strategies attenuated to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law. Moreover, it reveals the documental and international importance of this practice, at the same time that it exposes the compositional and normative difficulties with regard to legal and linguistic aspects
