Decision rules and information provision : monitoring vs manipulation

We analyze the contractual design problem of a principal who delegates decision-making and information provision. The principal faces two tasks: he has to decide the level of discretion to be granted to the decision-maker and to establish who is in charge of supplying the information. We show that these two choices are intrinsically related. When the decision-maker is granted high discretion, information provision is optimally delegated to the parties directly affected by the decision. Conversely, when the decision-maker enjoys little discretion, it is more desirable to rely on a third impartial agent. The paper helps rationalize some organizational arrangements that are commonly observed in the context of judicial and antitrust decision-making.

Curial exegese do art. 14, caput, da lei 9.307/96: hermenêutica lege ferenda ou real vontade do legislador?

Considerando toda a evolução da ciência processual, não há mais qualquer dúvida acerca da importância de se garantir juízes imparciais para o exercício da atividade jurisdicional. Em sede de arbitragem, a preocupação não poderia ser diferente. Dado que o árbitro exerce igualmente as prerrogativas concedidas pela jurisdição, sendo árbitro de fato e de direito, a necessidade de que sejam pessoas munidas de inquestionável imparcialidade e independência em relação às partes é ainda maior, dado que a confiança é o principal requisito para a função de tal munus. Desta forma, o trabalho pretende compreender se pode o princípio da autonomia da vontade das partes relativizar a proibição estabelecida em lei, que impede a atuação de árbitros quando incidentes nas hipóteses de impedimento e suspeição.

Mediação enquanto política pública : a percepção do profissional jurídico

O presente trabalho tem por objetivo explorar e descrever a percepção do profissional jurídico no município do Rio de Janeiro sobre o instituto da mediação. A mediação possui um enorme potencial para contribuir com a diminuição das demandas judicias e solucionar conflitos através da negociação com a presença de um terceiro imparcial. O profissional jurídico pode participar da mediação de diversas maneiras e sua visão com relação ao instituto é fundamental para que ocorra o conhecimento, a divulgação e a utilização desse procedimento. Por meio da análise dos fundamentos teóricos da mediação, da legislação brasileira e dos dados coletados pela aplicação de questionário, foi levantada a posição do profissional jurídico com relação ao instituto da mediação.

Interactive music visualization: implementation, realization and evaluation

This thesis describes all process of the development of music visualization, starting with the implementation, followed by realization and then evaluation. The main goal is to have to knowledge of how the audience live performance experience can be enhanced through music visualization. With music visualization is possible to give a better understanding about the music feelings constructing an intensive atmosphere in the live music performance, which enhances the connection between the live music and the audience through visuals. These visuals have to be related to the live music, furthermore has to quickly respond to live music changes and introduce novelty into the visuals. The mapping between music and visuals is the focus of this project, in order to improve the relationship between the live performance and the spectators. The implementation of music visualization is based on the translation of music into graphic visualizations, therefore at the beginning the project was based on the existent works. Later on, it was decided to introduce new ways of conveying music into visuals. Several attempts were made in order to discover the most efficient mapping between music and visualization so people can fully connect with the performance. Throughout this project, those attempts resulted in several music visualizations created for four live music performances, afterwards it was produced an online survey to evaluate those live performances with music visualization. In the end, all conclusions are presented based on the results of the online survey, and also is explained which music elements should be depicted in the visuals, plus how those visuals should respond to the selected music elements.

Avaliação da disponibilidade hídrica e da demanda hídrica no trecho do Rio Piranhas-Açu entre os açudes Coremas-mãe D´água e Armando Ribeiro Gonçalves

Piranhas-Açu basin is a Federal watershed with a drainage area of 43.681,5 km2, sited at Brazilian northeast semi arid, with 60% of your area in Paraiba State and 40% in Rio Grande do Norte State. The main river, Piranhas-Açu, has strategic importance for development of these states, because it s an essential source for many socio-economics activities developed along watercourse. The river s reach between Coremas-Mãe D`água Dam and Armando Ribeiro Gonçalves Dam has many irrigation projects, and supply many riverside cities. All this activities practiced in this river s reach consumes high water volumes. Due the importance of this stream and the necessity of an adequate management, this work aims for an impartial and detailed evaluation of real water supply conditions in this river s reach, by the application of hydrological modeling, including the arrangement of main dams in tributaries, and storage reservoir water balance. The rainfall-discharge model s applied in each sub-basins it was selected the model MODHISA- Hydrological Model of Semi Arid, that is a concentrated model with easy application. The simulation produced 50 years of inflows into the reservoirs, for which, were constructed the guaranties curves; and produced 50 years of synthetic discharge data in relevant points on the river and on its affluents; so it was constructed the permanence curves. Confronting the available discharge with the current and futures volumes of raw water captured in this river s reach, it was verified that de demands have high guaranties. This work concluded that the MODHISA Model is suitable to reproduce the hydrologic characteristics of Piranhas-Açu sub-basins, and showing good results

Cosmoeducação: uma abordagem transdisciplinar no ensino de astronomia

This work proposes a transdisciplinary approach that integrates transpersonal psychology exercises with astronomy teaching, seeking to allow one to reintegrate the sky in his/her daily life, expand his/her environmental awareness and eventually experiment the unity between human and cosmos. This proposal intends to collaborate with the supplying of education, which lacks initiatives of this kind, with the promotion of an integration of the scientific knowledge with the human experience that transcends the materialistic and fragmentary objectives of the current educational system. As a result of that lack, the teachers formation is also poor as for an integral and transdisciplinary approach. Besides, we also approached in this research the necessity to propose alternatives so that the educators may work in a more assertive way with the environmental and anthropological crisis in which we are living. Our working hypothesis is that the contents of astronomy, when they are dealt in a holisticanthropological focus and are related with transpersonal psychology practices, can come to be an efficient cultural-academic vehicle, capable of propitiating an expansion of consciousness and changes in the way one conceives the world. Such changes are necessary so that a more solidary, fair and ecologically balanced life may come to exist and prevail in the planet. Part of the collection of data was done through the ethnographic method, once an anthropological interpretation is inextricably associated with this kind of educational intervention, which will naturally include ethno-visions of the universe as well as specific cultural elements. In the beginning the scope of this research was a group of students attending the Astronomy assignment in an undergraduate Geography course (UFRN), in which we accomplished participant observation, half-open interviews and the first experimental practices mentioned. After the evaluation of the first data collected from that initial group, we elaborated an academic extension course, Laboratory in Cosmoeducation, and we offered it to teachers of the 1st and 2nd cycles of the fundamental level of the Alceu Amoroso Lima State School, located in the North Zone of Natal. We prized self-experimentation in that course, so that the teachers could enrich their repertoire of personal experiences, stimulating meditative reflections and eventual changes in the ways of conceiving the world and in their pedagogical practice. The transdisciplinary attitude permeated all our educational action, because this approach transcends the boundaries of disciplines, seeking essentially the integral development of the human being. The process has made us realize that the practice of looking at the sky , as a way of reintegrating it into daily life, provokes a process of expansion of the consciousness and of reintegration of the self in a wider level of environmental interrelation. According to the results, the occurrence of conceptual and existential changes of the world vision of the participant teachers was evident, reassuring ourselves of the idea that the interface between astronomy teaching and the practices of transpersonal psychology can contribute to the recovery of a holistic relationship between the human being and the cosmos and to inspire the arising of a more wide-ranging ethics, based on universal, impartial and sustainable values

Samba e negritude: práticas discursivas identitárias negras em sambas de enredo de temática africana

The study object of this thesis is the process of affirmation, (re)construction and (re)signification of the black identities in the discourses which cross the samba-enredo of African theme of the samba schools belonging to the elite group from the carioca carnival, in the period from 1960 and 2007. The main question which guides this research is the following: How does this discursive process occur and which are the possible effects resulting from it? This research aims to understand, through interpretation gestures of such discourses and from those which undergo the interview statements and the answers given to the questionnaires applied to spectators and parade exhibiters of these samba schools, in what way the negritude conception and the citizenship practice of the black Brazilian people, especially those from Rio de Janeiro, can be affected by the meaning production circulating in the discursive practices of these sambas. The research was theoretically related to the Applied Linguistics, however it articulates theories originated from Cultural Studies and Ethnic-racial Studies as well as it presents some theoretical and methodological fundamentals from the Discourse Analysis of French line. As concerns the methodology, it is of interpretative, qualitative basis with procedures of discursive character. The interview analysis did not reveal, as consequence of the discourses circulating in the sambas, a direct involvement of the black people who were interviewed in struggle for their citizenship practice, but it pointed out sliding of meaning in regard to the negritude emergence

Cinema itinerante no Rio Grande do Norte: aspectos da recepção

In itinerant film projects made in Brazil, the unique experience of watching movies on the big screen is held in open spaces, through the establishment of a contemporary ritual, under which the presence of spectators is primordial. Considering this dynamic of the performance of itinerant cinema, the main objective of this research is to analyze the process of reception of the spectators of the sessions of Cine Sesi Cultural, conducted by the Social Service Industry - Sesi, in Rio Grande do Norte state. The body of research was composed by the audience of the movie sessions of the edition developed in 2010. Analyses were made from the look on the specific audience of open sessions of this cinema project throughout a case study. Theoretical authors of Latin American as Jesus Martin-Barbero, Guillermo Orozco, Eliseo Veron and Nestor Garcia Canclini, which have important theoretical basis for the analysis of research on the cinematographic reception of the spectators, were taken as a basis. In this discussion are associated with contributions from Brazilian authors as Roseli Paulino, Fernando Mascarello, Mauro Wilton Souza, Nilda Jacks and Carolina Escostesguy. Besides the reception study, the research focuses on aspects that relate to and explain the circumstances in which itinerant cinema emerges as an alternative exhibition, for example, the context of the exhibition of films in the country, lack of public policies in the audiovisual sector, and mainly the closing of movie theaters in the inner cities of the country and the consequent migration of these rooms to the malls. Seeking to reduce the existing gap in the studies of the reception of spectators to the cinema in the country, this research presents a deeper analysis of the reception of the public of the itinerant cinema as a contribution to an important database for the diagnosis of projects such as the Cine Sesi Cultural

Multiflavor soldering

In two dimensions the simple addition of two chiral bosons of opposite chiralities does not lead to a full massless scalar field. Similarly, in three dimensions the addition of two Maxwell-Chern-Simons fields of opposite helicities +/- 1 will not produce a parity invariant Maxwell-Proca theory. An interference term between the opposite chiralities (helicities) states is required in order to obtain the expected result. The so-called soldering procedure provides the missing interference Lagrangian in both 2D and 3D cases. In two dimensions such interference term allows to fuse two chiral fermionic determinants into, a non-chiral one. In a recent work we have generalized this procedure by allowing the appearance of an extra parameter which takes two possible values and leads to two different soldered Lagrangians. Here we apply this generalized soldering in a bosonic theory which has appeared in a partial bosonization of the 3D gauged Thirring model with N flavors. The multiplicity of flavors allow new types of solderings and help us to understand the connection between different perturbative approaches to bosonization in 3D. In particular, we obtain an interference term which takes us from a multiflavor Niaxwell-Chern-Simons theory to a pair of self-dual and anti-self-dual theories when we combine together both fermionic determinants of +1/2 and -1/2 helicity fermions. An important role is played by a set of pure non-interacting Chern-Simons fields which amount to a normalization factor in the fermionic determinants and act like spectators in the original theory but play an active role in the soldering procedure. Our results suggest that the generalized soldering could be used to provide dual theories in both 2D and 3D cases. (c) 2007 Elsevier B.V. All rights reserved.
