Identidade e hibidrismo em Dalcídio Jurandir: a formação identitária de Alfredo, em Três casas e um rio

Este trabalho realiza uma leitura da obra Três Casas e um rio de Dalcídio Jurandir, seguindo alguns percursos para a formação da identidade de Alfredo. Preocupa-nos, primeiramente, verificar como a identidade de Alfredo se articula diante das diferenças culturais e dicotomias como popular/erudito; oral/escrito. Popular e oral, ligados a valores da mãe negra, D.Amélia, e erudito e escrito, relacionado ao pai, Major Alberto. Em seguida, apresenta os traços fronteiriços auxiliadores da elaboração da identidade de Alfredo, Finalmente, verifica-se como as narrativas presentes na obra estão incorporadas no texto dalcidiano, e sua importância para a resolução de alguns conflitos vivenciados pelo protagonista.E para que se possa visualizar a abordagens teóricas aqui trabalhadas, contribuem com este estudo autores como Stuart Hall, D. Shüller, Zilá Bernd e, ainda, serão citados Walter Benjamin, Anthony Giddens, entre outros.

A reeleição de vereadores evangélicos em Belém de 1992 a 2008: conexão, regra do jogo e comunicação com as bases

Em 2004 foram eleitos os vereadores que compunham a Câmara Municipal de Belém, tendo sido ocupadas às vagas deixadas por aqueles que não se reelegeram. Esse quadro da reeleição possibilitou a afirmação e fortalecimento de partidos políticos que, por vários mandatos, permanecem com representação política e assento no Parlamento Municipal. É o caso do Partido dos Trabalhadores (PT), do Partido do Movimento Democrático Brasileiro (PMDB), do Partido da Social Democracia Brasileira (PSDB), do Partido Trabalhista Brasileiro (PTB) entre outros.Esse grupo político tem estado representado no Parlamento municipal por um longo período ininterrupto. O campeão de renovação de mandato é o Vereador Pastor Paulo Queiroz da IEQ (Igreja do Evangelho Quadrangular) que está no seu quarto mandato. Em seguida, vem o Vereador Pastor Raul Batista da IURD (Igreja Universal do Reino de Deus) que está no seu terceiro mandato e o Vereador Iran Moraes da AD (Assembleia de Deus) que está no seu terceiro mandato. O ponto de partida da pesquisa, parte dos pressupostos sugeridos por Pereira e Rennó (2001) e sustentado por Downs (1958) de que, o objetivo central de um político é a busca de reeleição.Anthony Downs considera que o individuo dentro da sua racionalidade, tem a capacidade de interpretar as suas escolhas dentro de uma lógica de alternativas possíveis. Ele não se deixa ser seduzido pelos movimentos dos candidatos, mas, faz a sua escolha dentro das alternativas que se apresenta, mas mantém as escolhas racionais. Percebe-se que ao longo dos anos, os parlamentares evangélicos têm demonstrado maior força em algumas denominações em se manter no parlamento para vários mandatos. É o caso dos parlamentares da Igreja do Evangelho Quadrangular, Adventista do Sétimo Dia, Universal do reino de Deus, Assembleia de Deus. O processo de renovação contínua de mandato é baseado no apoio das lideranças e nos serviços prestados aos seguimentos internos das Igrejas.

A racionalização das tradições na modernidade: o diálogo entre Anthony Giddens e Jürgen Habermas

Based on the reflections of Habermas and his conception of modernity, understood as an unfinished project, Giddens stresses that in all societies the maintenance of personal identity and its connection to broader social identities is a primordial requirement for ontological security. To achieve ontological security, modernity had to (re) invent traditions and get away from genuine traditions, that is, those values radically linked to the pre-modern past. This is a character of the discontinuity of modernity, the separation between what is presented as the new and that which persists as the legacy of the old. This article discusses the relationship between tradition and modernity and the dialogue between Giddens and Habermas. The goal is to identify the points of contact and the differences in the theses defended by both authors, in order to assess their contributions to discussions of the rationalization of contemporary societies. Late or reflexive modernity is an uninterrupted process of changes that affect the foundations of Western society. Faced with a reality of constant change, it is necessary to choose between the certainty of the past and a new reality of continuous change. In this sense, and according to the Habermasian perspective, the reflexive character of modernity is found in this process of choosing between the certainties inherited from the past and new social forms, a process that that leads to the reflection on - or even the recasting of - social practices, causing the rationalization and (re) invention of various aspects of life in society.

Influence of the Hall effect on convection in plasmas

The influence of the Hall effect on stationary convection in shearless current-carrying plasma columns is considered. It is shown that the Hall effect can inhibit the formation of convection cells generated by viscosity and resistivity.

Nebraska Hall of Agricultural Achievement Dinner

What a treat to be here tonight to celebrate the achievements of some wonderful new additions to the Nebraska Hall of Agricultural Achievement. I can think of few experiences more-gratifying than those in which we get to say a heartfelt “well-done and thank you" to people who make significant contributions to the world around them by the way they live their lives and by the places they choose to put their talents and energies.

Cytogenic Evidence for the Specific Distinction of an Alaskan Marmot, Marmota broweri Hall and Gilmore (Mammalia: Sciuridae)

Cytogenetic studies based upon somatic cells (bone marrow) have disclosed that the marmot hitherto designated Marmota caligata broweri Hall and Gilmore, occurring in the Brooks Range of Arctic Alaska, differs from M. c. caligata (Eschscholtz) in number of chromosomes (2n=36 as compared with 2n=42 in M. caligata) and in proportions of chromosomal types. Typical karyograms for the two species are presented. It is concluded that the Brooks Range marmot is specifically distinct from M. caligata, the applicable name being Marmota broweri Hall and Gilmore. Also determined were diploid chromosome numbers for two other Nearctic species of marmots, M. flaviventris (Audubon and Bachman), with 42, and M. olympus (Merriam), with 40. It is suggested that M. broweri survived the last (Wisconsin) glaciations in the amphi-Beringian refugium, and that its closest affinities may be with one of the Eurasian species of Marmota.

The Somatic Chromosomes of Some North American Marmots (Sciuridae), with Remarks on the Relationships of Marmota browerii Hall and Gilmore

Karyotypes are defined for two nearctic species of marmots, Marmota olympus (2n = 40) and M. vancouverensis (2n = 42), and supplemental information is included on the karyotypes of M. flaviventris, M. monax ochracea, and M. marmota. The six North American species of Marmota (NF = 66) comprise a distinct group as compared with the middle Asian species (NF = 70) for which the karyotypes are known. Karyologic findings and zoogeographic evidence based upon the distribution of two nearctic species of host-specific cestodes indicate that M. broweri, in northern Alaska, is a pre-Würm relict. Its affinities appear to be with the North American caligata-group rather than with the northeastern Siberian M. camtschatica. The occurrence on M. broweri of the Asian flea, Oropsylla silantiewi, has not been explained. Some ecological and behavioral characteristics of M. broweri are briefly described and compared with those of other species. Family groups of M. broweri hibernate together in single winter dens that are plugged at the entrance; copulation takes place before the animals emerge from the winter den, near mid-May; face-glands are utilized in marking of territory. French abstract: Les auteurs définissent les caryotypes de deux espèces néarctiques de marmottes, Marmota olympus (2n=40) et M. vancouverensis (2n=42), et donnent des précisions sur les caryotypes de M. flaviventris, M. monax ochracea et M. marmota. Les six especes de Marmota (NF=66) d'Amérique du Nord forment un groupe distinct des espèces d'Asie centrale (NF=70) dont Ie caryotype est connu. Les données caryologiques et les preuves zoogéographiques basées sur la répartition de deux espèces néarctiques de cestodes spécifiques de I'hôte démontrent que M. broweri, dans l'Alaska septentrional, est une relicte du pré-Würm. Elle semble avoir plus d'affinités avec Ie groupe nord américain de caligata qu'avec M. camtschatica du nord de la Sibérie. La présence sur M. broweri de la puce asiatique, Oropsylla silantiewi, n'est pas expliquée. Quelques caractéristiques écologiques et éthologiques de M. broweri sont décrites brièvement et comparées avec celles d'autres espèces. Les groupes familiaux de M. broweri hibernent dans un meme terrier dont l'entrée est bouchée; la copulation à lieu avant que les animaux sortent de leur abri hivernal, it la mi-mai ; ils se servent de leurs glandes faciales pour marquer leur territoire.

Stuart Hall, cultural studies e a nostalgia da dominação hegemônica

Stuart Hall é um dos poucos autores contemporâneos que ainda se apóia no conceito de ideologia. Ela interfere na língua falada definindo limites, regulando a forma discursiva com a intenção de estabilizá-la e congelá-la. Ela domina o bloco histórico e a estratégia seria a de unir as camadas populares, a partir de dentro, para que estas possam fortificar-se e combatê-la. Mas todo esse esquema tem sabor nostálgico, como se houvesse uma manobra dos poderosos e os dominados não se identificassem com os signos de poder e prestígio. Como no caso da “leitura crítica”, não seria o caso de modernizar Stuart Hall?

Unconventional Hall effect near charge neutrality point in a two-dimensional electron-hole system

The transport properties of the two-dimensional system in HgTe-based quantum wells containing simultaneously electrons and holes of low densities are examined. The Hall resistance, as a function of perpendicular magnetic field, reveals an unconventional behavior, different from the classical N-shaped dependence typical for bipolar systems with electron-hole asymmetry. The quantum features of magnetotransport are explained by means of numerical calculation of the Landau level spectrum based on the Kane Hamiltonian. The origin of the quantum Hall plateau sigma(xy) = 0 near the charge neutrality point is attributed to special features of Landau quantization in our system.

Generalized correlation functions for conductance fluctuations and the mesoscopic spin Hall effect

We study the spin Hall conductance fluctuations in ballistic mesoscopic systems. We obtain universal expressions for the spin and charge current fluctuations, cast in terms of current-current autocorrelation functions. We show that the latter are conveniently parametrized as deformed Lorentzian shape lines, functions of an external applied magnetic field and the Fermi energy. We find that the charge current fluctuations show quite unique statistical features at the symplectic-unitary crossover regime. Our findings are based on an evaluation of the generalized transmission coefficients correlation functions within the stub model and are amenable to experimental test.

Magnetic field induced charge redistribution in artificially disordered quantum Hall superlattices

The photoluminescence from individual quantum wells of artificially disordered weakly coupled multi-layers embedded in wide AlGaAs parabolic wells was investigated in a strong magnetic field. We show that the response of the individual wells is very different from the average response of the multi-layers studied by transport measurements and that photoluminescence represents a local probe of the quantum Hall state formed in three-dimensional electron system. The observed magnetic field induced variations of the in-layer electron density demonstrate the formation of a new phase in the quasi-three-dimensional electron system. The sudden change in the local electron density found at the Landau filling factor nu = 1 by both the magneto-transport and the magneto-photoluminescence measurements was assigned to the quantum phase transition.
