Os exus em casa de catiço : etnografia, representações, magia

This dissertation is the result of an ethnographic journey undertaken in three spiritual centers of Umbanda , located in different districts of Natal/RN. The aim of the study was to understand how the representations of exus (spirit category) are established in the studied religious environment. In order to study this, mythical narratives of songs and of people were analyzed. In addition, the incorporated spirit entities, loaded with codes and values, were possible to be read and understood. The present work was developed according to a theoretical and methodological approach that interprets culture as a constant construction process, with representations and significations. The empirical research focuses on the ethnographic observations and the narratives; providing the experimentation of the models of discursive dialogues and polyphony. It was observed that the studied empirical field is marked by the cult of the Jurema which influences the mythical construction of exus . Therefore, this study enabled a reflection on the meeting of notions of two distinct worlds ( Umbanda and Jurema ). This reflection is crucial to the understanding of the position that exus occupy in the local umbandista system

Gestão compartilhada de P&D em petróleo:a interação entre a Petrobrás e a Universidade Federal do Rio Grande do Norte

This work addresses the relationship between University-Firm aims to understand the model of shared management of R&D in petroleum of Petrobras with UFRN. This is a case study which sought to investigate whether the model of cooperation established by the two institutions brings innovation to generate technical-scientific knowledge and contribute to the coordination with other actors in the promotion of technological innovation. In addition to desk research the necessary data for analysis were obtained by sending questionnaires to the coordinators of projects in R&D at the company and university. Also, interviews were conducted with subjects who participated in the study since its inception to the present day. This case study were analysed through the Resource-Based View and Interorganizational Networks theory. The sample data also stands that: searches were aligned to the strategic planning and that 29% of R&D projects have been successful on the scope of the proposed objectives (of which 11% were incorporated into business processes); which was produced technical and scientific knowledge caracterized by hundreds of national and international publications; thesis, dissertations, eleven patents, and radical and incremental innovations; the partnership has also brought benefits to the academic processes induced by the improved infrastructure UFRN and changing the "attitude" of the university (currently with national prominence in research and staff training for the oil sector). As for the model, the technical point of view, although it has some problems, it follows that it is appropriate. From the viewpoint of the management model is criticized for containing an excess of bureaucracy. From the standpoint of strategic allocation of resources from the legal framework needs to be reassessed, because it is focused only on the college level and it is understood that should also reach the high school given the new reality of the oil sector in Brazil. For this it is desirable to add the local government to this partnership. The set of information leads to the conclusion that the model is identified and named as a innovation of organizational arrangement here known as Shared Management of R&D in petroleum of Petrobras with UFRN. It is said that the shared management model it is possible to exist, which is a simple and effective way to manage partnerships between firms and Science and Technology Institutions. It was created by contingencies arising from regulatory stand points and resource dependence. The partnership is the result of a process of Convergence, Construction and Evaluation supported by the tripod Simplicity, Systematization and Continuity, important factors for its consolidation. In practice an organizational arrangement was built to manage innovative university-industry partnership that is defined by a dyadic relationship on two levels (institutional and technical, therefore governance is hybrid), by measuring the quarterly meetings of systematic and standardized financial contribution proportional to the advancement of research. These details have led to the establishment of a point of interaction between the scientific and technological-business dimension, demystifying they are two worlds apart

A escola normal de natal (Rio Grande do Norte, 1908-1971)

The research aims to analyze Professor Education in Natal, Rio Grande do Norte-Brazil in the period of 1908 to 1971. The work falls under the theme History of Scholar Institutions as well as Professor Education. The research investigates the evolution of the so called Normal School, a school that aimed professor education. It was based on assumptions by works of Chartier (1990), Chervel (1990), Elias (1994), Nóvoa (1987), Schriewer (2000), amongst others. The research dealt with a great array of documents in different institutions such as Minutes, Public Instruction Management Reports, Laws, newspaper articles (from the newspaper A Capital, A Ordem e A República), magazines such as Pedagogium (1921-1940); all of which present in the Geographical and Historical Institute of Rio Grande do Norte in Brazil. In the State´s public archive it was possible to find a book called Livro de Honra (1914-1919) as well as class diaries and books that contained details related to Scholar group Inscriptions. In the Atheneu Memorial the Atheneu Congregation of Normal School (1897) document was analyzed. In the Kennedy Superior Institute the researcher analyzed the Professor Nominal Graduation Registry Book. The work proposes a comparative study regarding the genesis present in the Lisbon Primary Normal School and the ones situated in Natal. The analysis dealt with institutional meanings attributed by educators. Documents from The Portuguese National Library as well as the Lisbon Superior Education School were analyzed. In this in environment, it was possible to analyze documents such as Minutes, Books, Manuals, Internal Regiments related to Pedagogy. The study allowed acknowledging that these Normal Schools emerged from the same historical substrate and present consonance between the two countries regarding once both were associated with politicians, professors, doctors, hygienists and professionals evolved with education. It was also possible to acknowledge that there is a presence of a pedagogical discourse attached to the primary school universe and professor education. The Natal Normal School was present in different contexts and was consolidated as an institution that was responsible for the education and preparation of primary school teachers. The school was considered a locus where it was possible to produce and work with specific knowledge in a peculiar fashion. This knowledge provided the necessary support for professor education and was in accordance with the world´s professional pedagogical movement as well as ideas, discussions and reflections. This school was considered a space for pedagogical activities, professional affirmation allowing action reflection enabling professor representation as knowledge producers legitimating professor instruction

Agentes Inteligentes com Foco de Atenção Afetivo em Simulações Baseadas em Agentes

Simulations based on cognitively rich agents can become a very intensive computing task, especially when the simulated environment represents a complex system. This situation becomes worse when time constraints are present. This kind of simulations would benefit from a mechanism that improves the way agents perceive and react to changes in these types of environments. In other worlds, an approach to improve the efficiency (performance and accuracy) in the decision process of autonomous agents in a simulation would be useful. In complex environments, and full of variables, it is possible that not every information available to the agent is necessary for its decision-making process, depending indeed, on the task being performed. Then, the agent would need to filter the coming perceptions in the same as we do with our attentions focus. By using a focus of attention, only the information that really matters to the agent running context are perceived (cognitively processed), which can improve the decision making process. The architecture proposed herein presents a structure for cognitive agents divided into two parts: 1) the main part contains the reasoning / planning process, knowledge and affective state of the agent, and 2) a set of behaviors that are triggered by planning in order to achieve the agent s goals. Each of these behaviors has a runtime dynamically adjustable focus of attention, adjusted according to the variation of the agent s affective state. The focus of each behavior is divided into a qualitative focus, which is responsible for the quality of the perceived data, and a quantitative focus, which is responsible for the quantity of the perceived data. Thus, the behavior will be able to filter the information sent by the agent sensors, and build a list of perceived elements containing only the information necessary to the agent, according to the context of the behavior that is currently running. Based on the human attention focus, the agent is also dotted of a affective state. The agent s affective state is based on theories of human emotion, mood and personality. This model serves as a basis for the mechanism of continuous adjustment of the agent s attention focus, both the qualitative and the quantative focus. With this mechanism, the agent can adjust its focus of attention during the execution of the behavior, in order to become more efficient in the face of environmental changes. The proposed architecture can be used in a very flexibly way. The focus of attention can work in a fixed way (neither the qualitative focus nor the quantitaive focus one changes), as well as using different combinations for the qualitative and quantitative foci variation. The architecture was built on a platform for BDI agents, but its design allows it to be used in any other type of agents, since the implementation is made only in the perception level layer of the agent. In order to evaluate the contribution proposed in this work, an extensive series of experiments were conducted on an agent-based simulation over a fire-growing scenario. In the simulations, the agents using the architecture proposed in this work are compared with similar agents (with the same reasoning model), but able to process all the information sent by the environment. Intuitively, it is expected that the omniscient agent would be more efficient, since they can handle all the possible option before taking a decision. However, the experiments showed that attention-focus based agents can be as efficient as the omniscient ones, with the advantage of being able to solve the same problems in a significantly reduced time. Thus, the experiments indicate the efficiency of the proposed architecture
