In the present work we make an incursion about the Reality Show, in a specific study of the program Big Brother 3 (BBB 3) approaching the question of Anonymity and Fame, though of its Narratives Strategic. We search to explain phenomenon of transformations of anonymous people in celebrities, showing all net of relationships established by the participants of BBB 3, during the together in the setting house, stage of the tram that tells the daily one of a group of youngs. Supported in concepts of it and Reality Show, the work is link the theories semiotic of means, proposal for Algirda Julien Greimas. We stand out strategies of the program, showing that they on the basis of structuralize elements fiction that stimulate and seduce the receiving public. How empirical reference, the work bases on the program Big Brother Brazil, shown for the Rede Globo de Televisão opened canal, in period of January 14 to April 01 of 2003. Ahead of the results gotten in analysis, we verify that BBB 3 is a format of reality and fiction. What although to create the effect of a hurt of real everything to show, its reality artificial, built principally for edition of the images

La dificultad que los alumnos encuentran en el aprendizaje de matemática viene siendo objeto de investigación por estudiosos en educación matemática, tanto en Brasil como en el exterior. El objetivo de este estudio consiste em investigar las dificuldades en el aprendizado sobre funciones matemáticas y la influencia de las concepciones alternativas a partir de los errores que los candidatos acerca de las cuestiones sobre funciones en la prueba objetiva de matemática del acceso a la universidad de los años de 2001 a 2008. Teniendo como cuestiones de estudio para alcanzar el objetivo propuesto: identificar la relevancia del tema funciones que son contemplados en las pruebas de acceso a la Universidad; asi como cuáles han sido los tipos de funciones más privilegiados y menos privilegiados; analizar si la contextualización de la pregunta y la presencia de elementos no textuales han influenciado en el aumento de tal dificultad; analizar si la representación semiótica agrega mayor exigencia a la pregunta; analizar respecto a la exigencia matemática de la pregunta; analizar lo que se refiere al desempeño de los candidatos para verificar cuál pregunta tuvo mejor desempeño y cuál el peor e identificar los errores más frecuentemente cometidos por los candidatos en esas pruebas. Las reflexiones de los estudiosos como: Radatz (1980), Cury (1994), Socas (1997), Borasi (1997), Franchi e Rincón (2004), Pochulu (2004) presentan las dificultades en el aprendizaje matemático, que aparecen a partir de los errores cometidos por los alumnos, quando estos errores reciben la influencia de las concepciones alternativas. El estudio que se presenta en esta disertación configura un análisis de los errores que los candidatos han cometido en las preguntas objetivas sobre el tema funciones de las pruebas de acceso a la Universidad de los años de 2001 a 2008, a partir de los relatorios de la Comissão Permanente do Vestibular COMPERVE/UFRN. Con la intención de alcanzar los objetivos propuestos para este estudio, fueran sido construidas categorías de análisis. Los resultados encontrados han sido: El tema funciones es el más frecuente entre los demás con (28,1%); el tipo de función priorizada durante esos años ha sido la función logarítmica con (24%); la contextualización de las preguntas exige una mayor comprensión por parte del candidato de lo que las situaciones directas; la caracterización semiótica posee elementos que estructuran esas preguntas que el educando debe saber asociar al texto; la exigencia matemática posibilitó analizar que el procedimiento medio ha sido el más requisitado; el desempeño de los candidatos ha sido en la mayoría bajo (50%); y los principales errores que ellos han cometido han sido de realizar traducciones incorrectas de las expresiones que aparecen en las situaciones-problema; utilizar todos los datos que aparezcan en el problema sin tomar en cuenta si el cálculo realizado responde a la pregunta solicitada; no interpretar coherentemente las informaciones del gráfico; decodificar incorrectamente los valores representados por literales en una recta numérica. Los resultados señalizan la necesidad de una revisión didáctico-metodológicas de la enseñanza de funciones a raíz de las cuales las dificultades en el aprendizaje se han presentado

Las pruebas de vestibular, en los últimos años en el Brasil, han sido objeto de diversas investigaciones, considerando que ese proceso selectivo es una de las vias para ingresar en las universidades públicas y termina por influenciar la enseñanza en las escuelas. De esa forma, algunos vestibulares han pasado por cambios, de un simple proceso selectivo clasificatorio a un proceso fundamentado en reflexiones sociológica, pedagógica y crítica, lo que ha promovido cuestionamientos respecto del aprendizaje y de su papel en la escuela. Delante de esa realidad, la Universidad Federal de Rio Grande del Norte (UFRN) ha implementado cambios en sus vestibulares procurando una aproximación a las Orientaciones Curriculares Nacionales, como los PCNEM, los PCN+ y las OCEM. Siendo así, el objetivo de este estudio fue caracterizar el avance cualitativo en las pruebas de preguntas objetivas a partir de los cambios ocurridos en el vestibular de la UFRN en el periodo de 1997 a 2010, definiéndose las siguientes cuestiones de estudio: ¿Cuáles son los tipos de preguntas que caracterizan las pruebas objetivas de Química del vestibular? ¿Cuáles cuestiones presentan las mayores dificultades para los candidatos? ¿Cuáles son los contenidos conceptuales privilegiados? ¿En qué tipo de preguntas los candidatos presentan mayores índices de éxitos? ¿Qué diferencias pueden ser establecidas entre las preguntas antes y después del periodo que establece los cambios en el vestibular de la UFRN? Las discusiones teóricas del estudio están fundamentadas en las siguientes referencias: PCNEM (BRASIL, 1999), PCN+ (BRASIL, 2001), OCEM (BRASIL, 2006), Zabala (1999), Jiménez Aleixandre et al. (2003), Pozo (1999), Álvarez de Zayas (1992), Núñez (2009), Relatorios Comperve/UFRN (1997 a 2010), e en relación a las evaluaciones: Pasquali et al. (2003), Silva y Núñez (2008), Marín y Benarrouch (2009). Para el estudio fueran construidas las siguientes categorías que permitieran el análisis de las cuestiones: contextualización de la cuestión, temas conceptuales, problema, representación semiótica, cálculo matemático, pertinencia de la cuestión e índice de acierto. Los resultados muestran un avance cualitativo de las preguntas de Química, en los cuales se observa un modelo de prueba que prioriza el uso de verdaderos problemas, de situaciones contextualizadas, de pocos cálculos, dándose prioridad al razonamiento que implica la comprensión, la aplicación y la interpretación de los conocimientos conceptuales, todo lo que puede estimular una enseñanza más adecuada en relación a las exigencias actuales de la Educación en Química

Studies about discursive genres peak at a necessity to understand how these genres work in a society that is more and more submissive to the technology of informatics such as ours. In acknowledging that the virtual context of the Internet provides the manifestation and development of new genres of the discourse, we perceived that the online journal, or blog, as commonly known, is responsible for a variety of linguistic phenomena that would normally take severaI years to consolidate. Since its appearance in 1997 blogs rush as a virtual version of the personal diary and in a short time due to communicative demands suffers several changes, making new categories of blog genres emerge. Facing such phenomena, this work intends at first to characterize blogs as a genre that exercises a social action, evidencing its formal, structural and pragmatic characteristics from the notion of recurrence and rhetoric in a discursive-semiotic perspective. The methodological postulates adopted by this research are considered of qualitative basis in the sense that they are not restricted to looking at the discursive events as a product, but mainly they take into consideration a group of situational, cultural and ideologic factors that are present in the constitution of genre.

The main objective of this study is to investigate the meanings of body and costume as essential components of television journalists aesthetic discourse, as exemplified by the presenters of Jornal Nacional, from Rede Globo. The study is inspired on the paths proposed by semiotics, and combines this approach with other techniques of scientific investigation to identify the meanings of this non-verbal communication form. For that, this work uses the concept of communication proposed by the Palo Alto School s authors, more specifically the concept of Watzlawick et al. (2005), which understands communication like relation and inherent of human beings. The precepts of complex thought and the hologramatic principle of Morin (1990), which value the union and the need to connect the knowledge of elements or parts to that of the systems these parts constitute, is also present in the thinking that guides the work. Throughout the chapters, we elucidate our understanding of body and television as media, and fashion and television journalism as languages. This work approaches a televisual history of Jornal Nacional in order to better understand the aesthetic proposed by television news over time, its presenters and costumes. The elements that are part of the televisual language s expression and content are addressed so that we can better understand the importance of body and presenters costume in this context. Finally, we conduct an analysis of the meanings of television journalism presenters body and costume through their stereotypes, their integration into the fashion cycle and also into the televisual analysis of the most important costume elements of Jornal Nacional s presenter couple: colors, models and accessories. We thus seek to strengthen the understanding of the wardrobe inseparable from the body as communication and detail some of their production understanding processes. The women historical role in brazilian television journalism, as well as masculinization of TV journalism environment are important elements to contextualize televisual language thinking in contemporary society. The investigation covers the origins, concepts, proposals, stereotypes, prejudices, reproductions, naturalizations and reinterpretation of the body and the costume of the presenters through time and the relationship between body, fashion and communication

The proposal of this research is to analyze the convergence between fashion and communication shown on the materiality of the print media, and how the language from the supporter influences on the production of sense by the target market. Made real in the research corpus comprised of six ffw>>mag! magazines from the year 2011. The applied conceptual mechanism tries to investigate the production of sense from the physical attributes before interpreting the message s content, to do so, the Materiality of Communication is used, which offers an investigative apparatus of the media in its material shape, and those as influences in the communicative acts and processes. Methodologically, we adopt the Peircean Semiotics Theory, for its study focus on the analysis of the possible processes of production of sense. Through Semiotics we achieve the interpretative levels that allow us to clarify the questionings that come from the research s objectives, identifying and tracing the cognitive and intelligibility schemes bound to the media speeches of materiality. The analysis coordinated to the concepts and theories employed in this study point to a confirmation that the materiality of the reviewed media communicates to the readers in the same intensity as its content, provides a preview of the content and notifies the intentions of the publication. In the commercial way, characterizing the target audience it craves, and also in the conceptual way, demonstrating the ideas it wants to communicate. Where the convergence between communication and fashion unfolds as the materiality of the media by the choice of the materials and finishing options, and mainly by the selection and manipulation of technical images and colors from the cycles of fashion

The development of digital technologies has opened up a new niche for artistic production. It began to emerge artworks that could only happen in the digital context. In this study, we investigated the syntax of defining digital poetry, recognized internationally as one of the possibilities of this new artistic practice, and how happens the meaning during the reading process. As research corpus, we chose the poem "Birds Still Warm From Flying", by american poet Jason Nelson. And we structure our analysis looking through three perspectives: the digital poem as a game; as the evolution of experimental trends of twentieth-century poetry; and as a representation of Rubik`s Cube, a famous three-dimensional puzzle from the 1970`s. Initially, we made some considerations about the construction of digital poetry as a hypermedia artwork, looking through convergence and hybridization of artistic and media languages. Then, we saw some similarities between Nelson`s poem and electronic games, based on our critical observations about the concept of interactivity. Subsequently, we wrote a historical overview about the poetic experimentation in the twentieth century, bringing examples of sound poetry and visual poetry as evidence that the birth of digital poetry is also the result of the evolution of these experiments. Finally, we use the Charles Sanders Peirce`s semiotics to analyze the signs that give references able to make us recognize the Rubik`s Cube in "Birds Still Warm From Flying"

With hardware and software technologies advance, it s also happenning modifications in the development models of computational systems. New methodologies for user interface specification are being created with user interface description languages (UIDL). The UIDLs are a way to have a precise description in a language with more abstraction and independent of how will be implemented. A great problem is that even using these nowadays methodologies, we still have a big distance between the UIDLs and its design, what means, the distance between abstract and concrete. The tool BRIDGE (Interface Design Generator Environment) was created with the intention of being a linking bridge between a specification language (the Interactive Message Modeling Language IMML) and its implementation in Java, linking the abstract (specification) to the concrete (implementation). IMML is a language based on models, that allows the designer works in distinct abstraction levels, being each model a distinct abstraction level. IMML is a XML language, that uses the Semiotic Engineering concepts, that deals the computational system, with the user interface and its elements like a metacommunicative artifact, where these elements must to transmit a message to the user about what task must to be realized and the way to reach this goal. With BRIDGE, we intend to supply a lot of support to the design task, being the user interface prototipation the greater of them. BRIDGE allows the design becomes easier and more intuitive coming from an interface specification language

The software development processes proposed by the most recent approaches in Software Engineering make use old models. UML was proposed as the standard language for modeling. The user interface is an important part of the software and has a fundamental importance to improve its usability. Unfortunately the standard UML does not offer appropriate resources to model user interfaces. Some proposals have already been proposed to solve this problem: some authors have been using models in the development of interfaces (Model Based Development) and some proposals to extend UML have been elaborated. But none of them considers the theoretical perspective presented by the semiotic engineering, that considers that, through the system, the designer should be able to communicate to the user what he can do, and how to use the system itself. This work presents Visual IMML, an UML Profile that emphasizes the aspects of the semiotic engineering. This Profile is based on IMML, that is a declarative textual language. The Visual IMML is a proposal that aims to improve the specification process by using a visual modeling (using diagrams) language. It proposes a new set of modeling elements (stereotypes) specifically designed to the specification and documentation of user interfaces, considering the aspects of communication, interaction and functionality in an integrated manner

Control and automation of residential environments domotics is emerging area of computing application. The development of computational systems for domotics is complex, due to the diversity of potential users, and because it is immerse in a context of emotional relationships and familiar construction. Currently, the focus of the development of this kind of system is directed, mainly, to physical and technological aspects. Due to the fact, gestural interaction in the present research is investigated under the view of Human-Computer Interaction (HCI). First, we approach the subject through the construction of a conceptual framework for discussion of challenges from the area, integrated to the dimensions: people, interaction mode and domotics. A further analysis of the domain is accomplished using the theoretical-methodological referential of Organizational Semiotics. After, we define recommendations to the diversity that base/inspire the inclusive design, guided by physical, perceptual and cognitive abilities, which aim to better represent the concerned diversity. Although developers have the support of gestural recognition technologies that help a faster development, these professionals face another difficulty by not restricting the gestural commands of the application to the standard gestures provided by development frameworks. Therefore, an abstraction of the gestural interaction was idealized through a formalization, described syntactically by construction blocks that originates a grammar of the gestural interaction and, semantically, approached under the view of the residential system. So, we define a set of metrics grounded in the recommendations that are described with information from the preestablished grammar, and still, we conceive and implement in Java, under the foundation of this grammar, a residential system based on gestural interaction for usage with Microsoft Kinect. Lastly, we accomplish an experiment with potential end users of the system, aiming to better analyze the research results

Ce travail a pour but d analyser un corpus de six textes hybrides, que nous classons comme des poèmes-chansons/ poèmes-chantés à cause de leur double présence dans deux systèmes sémiotiques différents. Le premier, la littérature, ou plus spécifiquement la poésie, a comme support le livre As Coisas [Les Choses], d Arnaldo Antunes et l autre, la chanson, est enregistré dans les disques du même auteur. Notre travail lance un regard sur ce corpus, en essayant de vérifier un aspect recourrent dans l oeuvre d Arnaldo Antunes qui est la présence da priméité, catégorie theórique développée par Charles Sanders Peirce. Au-delà de l observation de cet aspect sémiothique, nous ferons une discussion sur la chanson populaire, et ses rapports avec la poésie et par conséquent avec la Litterature. La théorie sémiothique s appuyera sur deux piliers : En ce qui concerne l étude de la priméité, nous travaillerons avec les théories de Peirce, mais en nous servant aussi des ouvrages de Lúcia Santaella, Winfried Nöth, Júlio Plaza et Décio Pignatari ; Dans l autre voie, pour ce qui concerne l analyse des chansons, nous utiliserons la théorie de Luiz Tatit, fondée sur la sémiothique de Algirdas Julien Greimas. Tatit trace une méthode d analyse, où il est possible d analyser une chanson en exploitant et le texte et la mélodie, ce qui permet une meilleure compréhension de l étude des poèmes-chansons et ses variations. Comme support pour la discussion sur la musique, nous nous servirons des théories de José Miguel Wisnik, Claude Lévi-Strauss, Roland Barthes et Jean Fisette

This research aims at studying the use of greeting cards, here understood as a literacy practice widely used in American society of the United States. In American culture, these cards become sources of information and memory about people‟s cycles of life, their experiences and their bonds of sociability enabled by means of the senses that the image and the word comprise. The main purpose of this work is to describe how this literacy practice occurs in American society. Theoretically, this research is based on studies of literacy (BARTON, HAMILTON, 1998; BAYHAM, 1995; HAMILTON, 2000; STREET, 1981, 1984, 1985, 1993, 2003), the contributions of social semiotics, associated with systemic-functional grammar (HALLIDAY; HASAN 1978, 1985, HALLIDAY, 1994, HALLIDAY; MATTHIESSEN, 2004), and the grammar of visual design (KRESS; LEITE-GARCIA, VAN LEEUWEN, 1997, 2004, 2006; KRESS; MATTHIESSEN, 2004). Methodologically, it is a study that falls within the qualitative paradigm of interpretative character, which adopts ethnographic tools in data generation. From this perspective, it makes use of “looking and asking” techniques (ERICKSON, 1986, p. 119), complemented by the technique of "registering", proposed by Paz (2008). The corpus comprises 104 printed cards, provided by users of this cultural artifact, from which we selected 24, and 11 e-cards, extracted from the internet, as well as verbalizations obtained by applying a questionnaire prepared with open questions asked in order to gather information about the perceptions and actions of these cards users with respect to this literacy practice. Data analysis reveals cultural, economic and social aspects of this practice and the belief that literacy practice of using printed greeting cards, despite the existence of virtual alternatives, is still very fruitful in American society. The study also allows users to comprehend that the cardholders position themselves and construct identities that are expressed in verbal and visual interaction in order to achieve the desired effect. As a result, it is understood that greeting cards are not unintentional, but loaded with ideology and power relations, among other aspects that are constitutive of them.
