This research examines the street children s identity construction processes. Recently, the research about this population has focused on the socialization processes that organize their everyday, their situations of interaction, the meanings of their social practices, their street experience. The concept of identitary forms gives coherence to the set of these phenomena, articulating them theoretically, in order to describe their life conditions and details of their trajectories. This research utilized an ethnographic approach with a group of 11 street people, 9 of them boys and girls 16-18 years old, during 3 months. It included participant observation, informal and formal interviews, that resulted in young s narratives of lifestory. These narratives were interpreted according to the principles of positioning analysis and the Labovian Analysis model of oral narratives of personal experience. The observation of interaction among the studied group and other groups has showed that their social practices, supported on many particular bodily technologies, recreate space and time of these interactions semantically, as mediation of meaning negotiations among groups. Such meanings transform again the environment of these interactions, disclosing interpretative systems by means of which the groups apprehend this interaction in a particular way. These street children s bodily technologies imply identitary forms based on scarcity and abandonment, paradoxicalally related to their self-concept. The analysis of narratives revealed diversity and complexity in the meanings assembly for their street experience; it showed that the semantic arrangements reconstruct the temporal experience, creating a moral climate for each lifestory, and determining more or less aperture of identitary forms to change. The study concludes that space and time, builders of interaction regimes, produce identitary forms; that the narratives and the social practices of the studied group are sustained upon a master discourse that opposes the meanings of the home and the life in the streets

This dissertation presents a model-driven and integrated approach to variability management, customization and execution of software processes. Our approach is founded on the principles and techniques of software product lines and model-driven engineering. Model-driven engineering provides support to the specification of software processes and their transformation to workflow specifications. Software product lines techniques allows the automatic variability management of process elements and fragments. Additionally, in our approach, workflow technologies enable the process execution in workflow engines. In order to evaluate the approach feasibility, we have implemented it using existing model-driven engineering technologies. The software processes are specified using Eclipse Process Framework (EPF). The automatic variability management of software processes has been implemented as an extension of an existing product derivation tool. Finally, ATL and Acceleo transformation languages are adopted to transform EPF process to jPDL workflow language specifications in order to enable the deployment and execution of software processes in the JBoss BPM workflow engine. The approach is evaluated through the modeling and modularization of the project management discipline of the Open Unified Process (OpenUP)

The component-based development of systems revolutionized the software development process, facilitating the maintenance, providing more confiability and reuse. Nevertheless, even with all the advantages of the development of components, their composition is an important concern. The verification through informal tests is not enough to achieve a safe composition, because they are not based on formal semantic models with which we are able to describe precisally a system s behaviour. In this context, formal methods provide ways to accurately specify systems through mathematical notations providing, among other benefits, more safety. The formal method CSP enables the specification of concurrent systems and verification of properties intrinsic to them, as well as the refinement among different models. Some approaches apply constraints using CSP, to check the behavior of composition between components, assisting in the verification of those components in advance. Hence, aiming to assist this process, considering that the software market increasingly requires more automation, reducing work and providing agility in business, this work presents a tool that automatizes the verification of composition among components, in which all complexity of formal language is kept hidden from users. Thus, through a simple interface, the tool BST (BRIC-Tool-Suport) helps to create and compose components, predicting, in advance, undesirable behaviors in the system, such as deadlocks

In this beginning of the XXI century, the Geology moves for new ways that demand a capacity to work with different information and new tools. It is within this context that the analog characterization has important in the prediction and understanding the lateral changes in the geometry and facies distribution. In the present work was developed a methodology for integration the geological and geophysical data in transitional recent deposits, the modeling of petroliferous reservoirs, the volume calculation and the uncertainties associate with this volume. For this purpose it was carried planialtimetric and geophysics (Ground Penetrating Radar) surveys in three areas of the Parnaíba River. With this information, it was possible to visualize the overlap of different estuary channels and make the delimitation of the channel geometry (width and thickness). For three-dimensional visualization and modeling were used two of the main reservoirs modeling software. These studies were performed with the collected parameters and the data of two reservoirs. The first was created with the Potiguar Basin wells data existents in the literature and corresponding to Açu IV unit. In the second case was used a real database of the Northern Sea. In the procedures of reservoirs modeling different workflows were created and generated five study cases with their volume calculation. Afterwards an analysis was realized to quantify the uncertainties in the geological modeling and their influence in the volume. This analysis was oriented to test the generating see and the analogous data use in the model construction

Software product line engineering promotes large software reuse by developing a system family that shares a set of developed core features, and enables the selection and customization of a set of variabilities that distinguish each software product family from the others. In order to address the time-to-market, the software industry has been using the clone-and-own technique to create and manage new software products or product lines. Despite its advantages, the clone-and-own approach brings several difficulties for the evolution and reconciliation of the software product lines, especially because of the code conflicts generated by the simultaneous evolution of the original software product line, called Source, and its cloned products, called Target. This thesis proposes an approach to evolve and reconcile cloned products based on mining software repositories and code conflict analysis techniques. The approach provides support to the identification of different kinds of code conflicts – lexical, structural and semantics – that can occur during development task integration – bug correction, enhancements and new use cases – from the original evolved software product line to the cloned product line. We have also conducted an empirical study of characterization of the code conflicts produced during the evolution and merging of two large-scale web information system product lines. The results of our study demonstrate the approach potential to automatically or semi-automatically solve several existing code conflicts thus contributing to reduce the complexity and costs of the reconciliation of cloned software product lines.

Cloud Computing is a paradigm that enables the access, in a simple and pervasive way, through the network, to shared and configurable computing resources. Such resources can be offered on demand to users in a pay-per-use model. With the advance of this paradigm, a single service offered by a cloud platform might not be enough to meet all the requirements of clients. Ergo, it is needed to compose services provided by different cloud platforms. However, current cloud platforms are not implemented using common standards, each one has its own APIs and development tools, which is a barrier for composing different services. In this context, the Cloud Integrator, a service-oriented middleware platform, provides an environment to facilitate the development and execution of multi-cloud applications. The applications are compositions of services, from different cloud platforms and, represented by abstract workflows. However, Cloud Integrator has some limitations, such as: (i) applications are locally executed; (ii) users cannot specify the application in terms of its inputs and outputs, and; (iii) experienced users cannot directly determine the concrete Web services that will perform the workflow. In order to deal with such limitations, this work proposes Cloud Stratus, a middleware platform that extends Cloud Integrator and offers different ways to specify an application: as an abstract workflow or a complete/partial execution flow. The platform enables the application deployment in cloud virtual machines, so that several users can access it through the Internet. It also supports the access and management of virtual machines in different cloud platforms and provides services monitoring mechanisms and assessment of QoS parameters. Cloud Stratus was validated through a case study that consists of an application that uses different services provided by different cloud platforms. Cloud Stratus was also evaluated through computing experiments that analyze the performance of its processes.

Cette recherche décrit la représentation discursive que la présidente Dilma Rousseff fait de soi-même, dans son discours devant le Congrès National, lors de la journée d’investiture, le 1/1/2011. Notre travail se situe dans le domaine théorique et méthodologique de la linguistique du texte et, plus spécialement, dans la perspective de l’Analyse Textuelle des Discours – ATD (ADAM, 2011 [2008a]), qui se définit comme « une théorie de la production co(n)textuelle de sens qui doit se fonder sur l’analyse de textes concrets ». Elle nous fournit la notion théorique et analytique de « représentation discursive », qui se focalise sur la dimension sémantique du texte. Nous nous appuyons, aussi, sur des travaux récents sur les représentations discursives, réalisés dans la recherche brésilienne sur l’ATD (RODRIGUES, PASSEGGI, SILVA NETO, 2010, 2012; RAMOS, 2011; OLIVEIRA, 2013; QUEIROZ, 2013; ZAMBLANO-OLIVEIRA, PASSEGGI, 2013). Les principales opérations sémantiques de construction de la représentation discursive utilisées dans notre travail sont la Référenciation et la Prédication. L’approche méthodologique est, en même temps, qualitative et quantitative, priorisant l’identification des occurrences, ainsi que la description détaillée de leurs valeurs sémantiques et textuelles. Les résultats de la recherche sont de trois ordres : méthodologique, théorique et descriptif-interprétatif. Méthodologique : nous proposons une approche que nous désignons comme « marquage textuel » (ou « mappage textuel ») qui permet de marquer (étiqueter) les valeurs sémantiques des formes linguistiques, permettant leur identification dans le flux textuel, c.-à-d., dans la dimension séquentiellecompositionnelle du texte. Théorique : nous introduisons la notion de « domaines de la représentation discursive » qui organisent et articulent les différents éléments qui composent la représentation discursive de la présidente. Quant aux résultats descriptifsinterprétatifs du discours de l’investiture, ils indiquent que la représentation discursive de la présidente se configure au moyen de différents domaines conceptuels, explicités par les référenciations et les prédications. Ils mettent en relief les désignations et les actions / états, aussi bien de la femme – domaine du genre – que de la présidente – domaine du rôle politique et institutionnel. La présidente se représente explicitement et avec emphase comme l’agent responsable par les actions exprimées par les prédications verbales (verbes d’action), consciente de l’importance de son rôle politique et social. Les prédications nominales signalent clairement une représentation discursive qui englobe les domaines conceptuels politique, moral, éthique, comportemental et émotionnel (forte, accueillante, pionnière, consolidatrice, infatigable, humble, engagée, démocrate, victorieuse et courageuse). Le discours d’investiture réalise, donc, des désignations positives de la présidente, lesquelles se situent dans un temps présent et prospectif – avec des perspectives de futur – comme leader politique du Brésil, avec une participation active dans la transformation du pays, tenant compte aussi de son histoire de vie, sa biographie de luttes. Ainsi, la description empirique et l’interprétation de ce discours particulier contribue à l’analyse textuelle des représentations discursives dans le discours politique brésilien contemporain. Elle soulève, aussi, des questions théoriques et méthodologiques qui nous semblent pertinentes pour le développement de cette aproche.

We study the use of nominal suffixes of degree, such as -inho, -ão, -íssimo, -ílimo, -érrimo in written texts in Brazilian Portuguese, by focusing on semantic, cognitive, pragmatic and discourse aspects involved in using these suffixes. In general, we aim to identify semanticcognitive and discourse-pragmatic factors that motivate the usage of nominal suffixes of degree and to contribute for the study of degree in Portuguese class in Basic Education. The theoretical perspective underlying our research is the Linguística Funcional Centrada no Uso, as conceived by group of researchers of Discurso & Gramática (FURTADO DA CUNHA, BISPO, SILVA, 2013; MARTELOTTA, 2011). According to this theoretical model, language model uses the shape of the grammar of a language at the same time they are provisioned for it. In this sense, speech and grammar influence each other. In terms of methodology, we make an eminently qualitative research with quantitative support as evidence of use of trend. It is characterized also by descriptive and interpretive bias of the phenomenon under study. Empirical evidence from our analysis come from a corpus consisting of written texts from Veja magazine, January to June 2011 issues, particularly Carta do Leitor e Gente sections, the latter representative of the Coluna Social magazine. The results of our analysis showed that the use of nominal graders suffixes are related to semantic-cognitive factors (construction of certain text directions, the association more grounded aspects of concrete experience or the more abstract meanings, for example), the discourse-pragmatic issues (range certain communicative purposes, as critique, judge, mock, claim, involving the reader, seeking her membership of a particular point of view). In addition, we found that the use of these morphic elements in genres of the sample analyzed were related to the subjectivity of the writer and the inter-subjective issues involving writer and reader, as Traugott and Dasher (2002). Finally, we contemplate discussion about the approach of our object of study in Portuguese classes in Basic Education.

This dissertation analyses the Brazilian Supreme Court’s judgement in the Non-compliance Action of the Fundamental Precept 132/RJ and in the Direct Action of Unconstitutionality 4277/DF, which created in the country the same-sex civil union. In This decision, the STF interpreted according to the constitution Article 1.723 of the Civil Code, invoking several fundamentals reaffirmed in the Constitution. From all these laws invoked by the Supreme Court to support the pretorian creation, the content of consitutional Law regarding equality is the only that corresponds, and it is sufficient to evidence the necessity of the creation, by legislator, of the institute for civil rights, since the Constitution forbids distinctions that is not expressly provided for in the Constitution (Art. 3º, IV, of Federal Constitution). In this way, Article 226, § 3º is not an exception capable of satisfying the condition of the consitutional foresight because although it protect, according its content only the civil union “between the man and the woman”, it is not able to forbid the creation, by legislator, of another kinds of families, including the same-sex civil union. As such, the reasoning, now legitimate according to the legislator, is not support the creation of institute by Constitutional Court, because the Court may enforce the Law, interpreting in the purviews allowed by the legal text and its constitutionality. In regard to the civil union of individuos of the same sex, the Court could not deduce that such union was implied by Law, like the interpretation according to the Constitution given by judges, on grounds of semantic purviews of the words man and woman, existents in both articles. The Court could not created it either, exceeding the legal system role. So, upon the institute creation, the STF, exceeded two limits: the interpretation and Law enforcement.

Specific educational material production for a group of level IV – 8th and 9th years of Youth and Adults Education, having as starting point the reading of a series of letter of correspondence between Câmara Cascudo and Mário de Andrade in the 1920s, and the verification of the way the dialog between the two authors reveals elements that transpire themselves in the tale entitled “Piá não sofre? Sofre”, from the book Os contos de Belazarte, de Mário de Andrade. The educational material production was preceded by the analysis of the selected tale, which will be studied along with some of the letters, in an analysis of the textual, discursive and semantic features of the text in representation of these both genres: letter and tale. The selected tale was written between 1923 and 1926, dates close to the years when the author came by Rio Grande do Norte state, in the years from 1927 to 1929, accompanied by Câmara Cascudo, being also this period that there are records of letters in the set of correspondence between them. To the reading of the selected material, it was used theoretical references from literature and literary historiography, especially the history of Brazilian modernist movement. To the production of the educational material, it was chosen as theoretical reference the accumulated knowledge in the area of literature teaching, literacy and the recommendations of the Brazilian National Curriculum Parameters. The methodology in this study was constructed from the theoretical references and had as basic support the study of didactic sequences from which a specific thematic unit got its shape from, required by the analyzed material and tested in a classroom.

In this dissertation we reflect about sensitive the dimension of the body, which enables us to participate in mythical space and set him as a potential space for artistic creation in dance, experience provider in senses for world, for life and for existence. It´s a written, thrashing some reflections on the human condition from a gaze cast upon the myth of Adam, leading us to think about the possible relationships between art and myth in contemporary times, as fields of knowledge open to creation, and semantic spaces able to assign new meanings to living through the pulsations of a body that is myth and what is dance. One of the goals of this study is set up a new point of view to analyze the Adam's myth, enabling to new interpretations, meanings and understandings from the experience in the process of creation in contemporary dance. Therefore, methodologically reference is made in the Phenomenology, or rather the phenomenological attitude proposed by Merleau-Ponty (1994), which considers the experience of the body as the primary source of knowledge. Dipping on this process of creation in contemporary dance, one artistic and choreographic work was originated, titled "The Body I am”, in contemplation of this dance that echoes the mystery, that emerges from the depths of the body, and it brings to the human surface and your world, your relationships. Realize that dance is as a sensitive guide and counselor reflections ontological and epistemological, able to validate and perpetuate the myth whereas ancestral wisdom inheritance.

A partir de um conjunto de dados obtidos em pesquisa, o texto deseja salientar uma face pouco examinada pelos estudiosos do espiritismo no Brasil: aquela dos grupos espíritas que cultuam extraterrestres. Examina a narrativa Rebelião de Lúcifer, escrita pelo médium potiguar Jan Val Ellam. Sustenta que esta atualiza noções importantes em relação a narrativas de salvação anteriores construídas pelo espiritismo. Destaca em especial o aprimoramento racial e moral através da reencarnação em distintos corpos humanos e em diferentes planetas. Examina-os a partir das noções de exílio planetário e de evolução racializada. Argumenta que Jan Val Ellam as atualiza através da categoria nativa Povo de Alt’Lam e através de bricolagem com outros campos semânticos, notadamente a ufologia e a fi cção científica
