Formação e vivências: a representação social do ser professor em comunidades ribeirinhas do Vale do Juruá Acre

Being a teacher is a challenging task, driving action strategies that mobilize technical dimensions of being / doing teaching, but also affection. This research was conducted with teachers / students of the Special Program of formation for Teachers of Basic Education agricultural zone (PROFIR) developed by the Federal University of Acre in partnership with the State Department of Education (SEE) and City Halls of the region; locus typically Amazon and, in this research, comprises five municipalities in the Valley of Juruá - Acre. Northern Brazil. It Aims to capture the social representation of being a teacher in riverside communities. We performed this study from the Theory of Social Representations (MOSCOVICI, 1978, 1990, 2005a, 2005b, 2009, 2011) and (JODELET, 2001), from discussions on teacher formation (LDB No. 9394 of 1996). Work, among others, (TARDIF, 2004), (TARDIF; LESSARD, 2007), (NÓVOA, 1992, 1999), (ARROYO, 2007). We used as a methodological strategy, the multiple classification procedure (PCM), which is organized in two steps: Free Classification and Directed Classification, as well as semi-structured interviews, involving, thus, 137 teachers surveyed. For the analysis of the data, we appealed to software SPSS, version 13.0 for Windows, mapping the elements of the representational content through Multidimensional Analysis (MSA and SSA). Through the different strategies of analysis, we identified from the Free Classification, the regionalization: Beyond forest, teaching Attributes and Mobilized Attributes. With data of the Directed Classification, the analysis was based on the Theory of Facets (BILSKY, 2003) and (BUSCHINI, 2005) and we found: Reference of teacher; Negative Dimension and affective and technicians attributes. Finally, with the Analysis of Content (BARDIN, 2004) e (FRANK, 2005) and of the interviews the categories we found the categories: Urban relation versus agricultural, Knowledge in construction and possible bets. The report of the experiences along the edge of the rivers, in these different methodological strategies and of analysis, demonstrates the existence of symbolic and representational elements that influence and guide the educational conduct and actions of these teachers and that they are deeply anchored and objectified in technical and affective elements of the making teacher. They daily live deeply the concreteness of the Amazonian realism redesigning the Real and the symbolic one as a way to understand themselves as a teacher in adversity of this context. We also observed the historical, social and cultural local marks, framing, thus, the collective personality and generating its guides of action

Mapeamento robótico 2,5-D com representação em grade de ocupação-elevação

This work introduces a new method for environment mapping with three-dimensional information from visual information for robotic accurate navigation. Many approaches of 3D mapping using occupancy grid typically requires high computacional effort to both build and store the map. We introduce an 2.5-D occupancy-elevation grid mapping, which is a discrete mapping approach, where each cell stores the occupancy probability, the height of the terrain at current place in the environment and the variance of this height. This 2.5-dimensional representation allows that a mobile robot to know whether a place in the environment is occupied by an obstacle and the height of this obstacle, thus, it can decide if is possible to traverse the obstacle. Sensorial informations necessary to construct the map is provided by a stereo vision system, which has been modeled with a robust probabilistic approach, considering the noise present in the stereo processing. The resulting maps favors the execution of tasks like decision making in the autonomous navigation, exploration, localization and path planning. Experiments carried out with a real mobile robots demonstrates that this proposed approach yields useful maps for robot autonomous navigation

Multi-resolução com fóvea móvel para redução e abstração de dados em tempo real

We propose a new approach to reduction and abstraction of visual information for robotics vision applications. Basically, we propose to use a multi-resolution representation in combination with a moving fovea for reducing the amount of information from an image. We introduce the mathematical formalization of the moving fovea approach and mapping functions that help to use this model. Two indexes (resolution and cost) are proposed that can be useful to choose the proposed model variables. With this new theoretical approach, it is possible to apply several filters, to calculate disparity and to obtain motion analysis in real time (less than 33ms to process an image pair at a notebook AMD Turion Dual Core 2GHz). As the main result, most of time, the moving fovea allows the robot not to perform physical motion of its robotics devices to keep a possible region of interest visible in both images. We validate the proposed model with experimental results

Em direção a uma representação para equações algébricas :uma lógica equacional local

The intervalar arithmetic well-known as arithmetic of Moore, doesn't possess the same properties of the real numbers, and for this reason, it is confronted with a problem of operative nature, when we want to solve intervalar equations as extension of real equations by the usual equality and of the intervalar arithmetic, for this not to possess the inverse addictive, as well as, the property of the distributivity of the multiplication for the sum doesn t be valid for any triplet of intervals. The lack of those properties disables the use of equacional logic, so much for the resolution of an intervalar equation using the same, as for a representation of a real equation, and still, for the algebraic verification of properties of a computational system, whose data are real numbers represented by intervals. However, with the notion of order of information and of approach on intervals, introduced by Acióly[6] in 1991, the idea of an intervalar equation appears to represent a real equation satisfactorily, since the terms of the intervalar equation carry the information about the solution of the real equation. In 1999, Santiago proposed the notion of simple equality and, later on, local equality for intervals [8] and [33]. Based on that idea, this dissertation extends Santiago's local groups for local algebras, following the idea of Σ-algebras according to (Hennessy[31], 1988) and (Santiago[7], 1995). One of the contributions of this dissertation, is the theorem 5.1.3.2 that it guarantees that, when deducing a local Σ-equation E t t in the proposed system SDedLoc(E), the interpretations of t and t' will be locally the same in any local Σ-algebra that satisfies the group of fixed equations local E, whenever t and t have meaning in A. This assures to a kind of safety between the local equacional logic and the local algebras

Segregação socioespacial e turismo: estudo da representação fílmica criada pelos turistas e residentes sobre Natal Rio Grande do Norte

This study emerges and develops, from a note by Italo Calvino, who in his novel Invisible Cities advised to avoid saying "that sometimes different cities follow on the same site and with the same name, born and die without knowing, without communication among itself ". The research with a transdisciplinary work ( using elements of sociology, anthropology, geography and communication) made a reflection about segregation and tourism: poverty-richness, center-periphery, tradition- spectaclezation , the visitor-visited maping the touristic circuit and discussing about the phenomenon on the real city and touristic place: Natal and the "Sun City" - Rio Grande do Norte, studying videos produced by residents (documentary) and tourists ( posted on the Internet). Doing a comparative analysis between the realities of these two subjects (resident and tourist), the research found few similarities, many differences on the urban experience, with the existence of two distinct realities (tourist region X the periphery region). Based on theory of phenomenology, social representation, and using content analysis of film, it was noted that promotes to the visitor a trip segmented and disintegrated to daily life, culture and contact with the resident. Resident that, in largely part, lives in a unattended area, with no prospect of life (represented by Novo Horizonte Community). The confinement and segregation occurs even in his moments of leisure and cultural expressions (represented by Redinha‟s Beach), because the private an public leisure areas of tourism indirectly prevent access by people who can not contribute to the consumption on this places. This papper concluded that the tourism in Natal is an activity-phenomenon that directs and focuses on public investments for infrastructure tourist region (Ponta Negra Beach), in detriment of the poorest and periphery areas of the city

O governo protetor: a representação do poder político em cerimoniais régios portugueses (séc. XVIII-XIX)

Ao inventariarmos as grandes celebrações da monarquia portuguesa, encontraremos algumas que são cerimoniais eminentemente religiosos. Dentre eles, há a procissão do Anjo da Guarda do Reino de Portugal (no terceiro domingo de julho), instituída no século XVI como celebração da realeza, das quais toda a Corte participava e eram realizadas por todo o reino português. Também as aclamações de Da. Maria I (1777) e D. João VI (1818) utilizam elementos de caráter religioso (símbolos e idéias). Estas celebrações colocam-nos a hipótese de uma série de articulações entre os procedimentos religiosos e o poder real. em função do exame daquelas procissões e destes cerimoniais, procuramos esboçar uma imagem do rei português: um rei-protetor, detentor de um poder de salvação.

Diálogo de máscaras em Cardoso Pires: a suspeita diante do ser e do real

Discurso paradoxal e ambíguo, onde o sujeito ora desaparece na rede infinita dos signos, ora reaparece em busca de sua identidade, a narrativa de Cardoso Pires trabalha com a idéia de uma subjetividade constituída não por uma essência metafísica, mas por códigos, textos, imagens e outros artefatos culturais. A problemática dos aspectos ilusórios da vida constitui um dos temas obsessivos de sua obra, ponto de confluência entre as perplexidades do autor, das personagens e do leitor, que, juntos, procuram um significado para a vida e a morte, buscando dar nome ao nada.Palavras-chave: Literatura portuguesa; ficção contemporânea; sujeito pós-moderno; ficção e realidade; códigos de representação social.
