Resumo: O presente estudo é um esforço de aproximação da dinâmica sociopolítica Katukina, grupo da família lingüística pano residente nas Terras Indígenas Gregório e Campinas, ambas no estado do Acre, Brasil. Através de pesquisa em fontes etnológicas, historiográficas e de minha própria etnografia, busco uma aproximação das relações que os Katukina constituíram com não-indígenas durante o período da colonização da região do Alto Juruá e aquelas que vem constituindo contemporaneamente a partir da noção de "conhecimentos tradicionais". Para tanto, insiro uma reflexão sobre a dinâmica sociopolítica nativa, pensada em termos tanto da constituição dos grupos domésticos e das aldeias, como também de um esquema relacional que perpassa os contatos com diversas formas de alteridade. Se a dinâmica sociopolítica nativa pressupõe a existência de inúmeros domínios com os quais a relação é a um só tempo produtiva e perigosa, devendo ser, portanto, equilibrada, que produtividade e que perigos estão latentes à intensificação das relações com os domínios não-indígenas? Que questões por sua vez este contato insere aos não-índios? Como veremos as relações interétnicas permeiam esta dissertação na medida em que o cotidiano Katukina/Noke Koï nos dias de hoje é permeado por elas. A busca por constituir este quadro parte da dinâmica nativa.
Abstract: The present study is an attempt to approach the Katukina sociopolitical dyinamics, a group from Pano linguistic family resident in Gregório and Campinas Indegenous land, both located in the state of Acre, Brazil. By sourching in etnological and historical sources and from my own etnolography, I seek an approchement of relations that the Katukina constituted with non-Indians during the colonization period of upper Juruá region and from those that have been constituting contemporaneously from the concept of traditional knowledge. To do that, I propose a reflection on the native sociopolitical dynamic conceived not only in terms of the constitution of the domestic groups and villages but also as a relational schema that encompasses the contacts with various forms of otherness. Considering that the sociopolitical dynamic native assumes the existence of many domains with which the relationship is at the same time productive and dangerous, and should therefore be balanced, what productivity and what dangers are latent to the intensification of relations with non-indigenous domains? What issues this contact inserts to the non-Indians? As we are going to see, the interethnic relations permeate this dissertation by the time that the daily Katukina / Noke Koï routine is permeated by them. The efforts to constitute this, are part of the native dynamic.

Full textDos grafos son gemelos si son mutuamente subgrafos entre sí. En grafos finitos la única forma de que dos grafos sean mutuamente subgrafos entre sí es que sean isomorfos. Sin embargo, en grafos infinitos existen grafos que se incluyen mutuamente y no isomorfos entre sí. Bonato y Tardif [3] se preguntaron por la cantidad de gemelos que puede tener un grafo. La conjetura de alternativa en árboles plantea que si un árbol tiene gemelos no isomorfos a él, entonces tiene infinitos gemelos. En el presente trabajo se presenta una demostración de la conjetura para árboles localmente finitos con una cantidad contable de ends. Se comienza realizando una revisión general de los conceptos y teoremas de grafos infinitos. Se introducen los conceptos básicos de grafos infinitos (rayo, doble rayo, end etc). Luego se estudia también una topología definible para un grafo infinito, que describe de mejor manera el grafo y sus ends que es de relevancia en la demostración dada posteriormente. Posteriormente se estudian los conceptos, definiciones y teoremas propios de la conjetura. Se revisarán los trabajos hechos hasta ahora, las ideas que han surgido a partir de intentos para demostrar la conjetura y la descripción de un grafo con propiedades interesantes. A continuación se estudia en detalle la relación subgrafo en grafos infinitos. Se introduce el concepto de morfismo y se muestra su relación con los conceptos de subgrafo e isomorfismo. También se estudia el grupo de automorfismos del doble rayo y de árboles finitos. Se mostrará además una forma de definir isomorfismos entre árboles infinitos localmente finitos a partir de isomorfismos locales. También se estudiará la construcción de isomorfismos definidos por componentes. Luego, se demuestra la conjetura para árboles con una cantidad finita de ends. Primero se demuestra la conjetura para árboles con exactamente un end, luego con exactamente dos ends y finalmente para árboles con más de 2 ends. Finalmente, se demuestra la conjetura para árboles con una cantidad infinita contable de ends. Se introduce el concepto de centro-end y a partir de éste se demostrará una extensión de un teorema dado por Halin [7] para árboles con una cantidad contable de ends. Este resultado fue dado por Polat y Sabidussi [9] para automorfismos, se presenta una demostración alternativa que también abarca endomorfismos. Usando esta extensión se demuestra la conjetura. Se define el concepto de ecuación gráfica, que junto con el teorema extendido de Halin permiten demostrar la conjetura en el caso más difícil.

Full textNeurotics Anonymous is an association formed by self-help groups bringing together individuais who consider themselves with emotional disturbances by following the Alcoholics Anonymous recovery Program adapted to your purposes. Based on ethnographic research, including participant observation conducted at the meetings of three groups located in the city of São Paulo, it was characterized forms of participation, the activities of groups, motivations, beliefs and values of the participants, also considering organizational and historical aspects of the association and its Program. Considering the ongoing process of individuation, this research sought to understand the role played by the institution in guiding the behavior of its members in relation to their specific demands related to common problems of everyday life. From the examination of socialization experienced by group participants, it is shown as the participation engenders processes of identification between individuais who go through similar problems, requiring each one the active involvement and subjective motivation - the formulation of a project for themselves and others through autonomous construction of a life narrative for themselves. It is argued that the role of institutions for individuais changed, not determining the direction in which they should draw their destinations throughout life, not serving to guide them completely as the many problems that arise for them in everyday life. That is, individuais select one among many others existing institutions, which they participate and for which they are socialized lifelong, to solve certain types of problems and not others.

Full textIn this work we present an analytical solution for the one-dimensional diffusion equation in cylindrical geometry from Perturbation Theory inside a homogeneous cylinder by the Hankel Transform. We present analytical solutions for fixed source problem. We solved also a monoenergetic case inside a heterogeneous cylinder using a recursive formulation together with the Hankel Transform. We obtained an analytical solution for the time-dependent diffusion equation using the Finite Hankel Transform. Once the flux of neutrons except for a constant of integration, we apply boundary and interface conditions. After evaluating this constants we obtain the final flux. The obtained results of this work are compared with the literature, as well as some specific approximations are explain throughout this work.

Full textSignificant social, economic and political changes took place in the Brazilian Republic in the end of 19th century. In this context, socio-political forces operated in the civilization proposal of country supported in the dissemination of educational institutions as a strategy to match the modernization and progress of European countries. So School Groups were created in opposition to distant schools of the monarchy period, innovating in the Brazilian scenario with the implementation of graduate education and the intuitive method, serving as an advertisement of the new government. Some studies have shown that a change was implanted in the clitic placement in prepositional infinitive sentences in Brazilian Portuguese in the turn of 19th century, which distanced from both the standard European Portuguese and the Brazilian vernacular use. Considering the increase of proclisis of Brazilian vernacular (OLIVEIRA, 2013) and the majority enclitic of republican intellectuals of São Paulo (SANTOS SILVA, 2012) in this syntactic context, this study will investigate if the School Groups of São Paulo adopted a single linguistic standard about the clitic placement in prepositional infinitive sentences. For this analysis, formal texts written in 1902 and 1906 by directors of 34 School Groups and education inspectors of São Paulo will be studied. For a satisfactory analysis, the evidential paradigm of Ginzburg (1898) will be adopted, along with an ethnographic study of School Groups and their curriculum that will identify the background of the propagation of this new kind of school and understand the symbolic matter of this educational institution for the republican society. So the linguistic point of view can be interlace with the socio-history of School Groups of São Paulo in the turn of 20th century.

Full textIn this work we stablish the Central Limit Theorem for the hierarchical O(N) Heisenberg model at criticality via partial differential equation in the limit N -> infinity. For simplicity we only treat the d = 4 case but the theorem is still valid for d > 4. By studying a given partial differential equation (PDE) we determine for any d > 2 the critical inverse temperature of the continuum hierarchical spherical model, and we show a connection between criticality and the fixed point of PDE. By means of a geometric analysis of the critical trajectory we obtain some informations about Lee-Yang zeros´s dynamics and distribution.
