O processo de institucionalização do curso de administração a distância da UFRN

This work aims to describe how is occurring through the process of institutionalizing the Administration distance course of UFRN. To this end, structured into two parts: through research and analysis of content, sought to impound as if gave historic process of creation, as well as identify variables isomórficas, proposed by Powell and DiMaggio (1991), on the actions undertaken, and still present, institutional actors-having been found three typologies; then investigated the process itself, analyzing the factors of institutionalization suggested Esman (1966-1972), internal structure doctrine, leadership programme, resources, links and exchanges, from the political plan educational course. As the research methodology was defined as qualitative, even though I used survey to collect, reviewed the second ANOVA. The results found in this step pointed out that only the doctrine and internal structure variables are consistent with the assumptions of model; we found for other, discharged indicated a gap between the political acts contemplated in teaching and the actions taken so far, unfavourable element to its legitimacy. However, although the implications found in the analysis of these factors suggest that this course can derive one more discontinuous Government proposal of distance course, this study believes that are still reasonable assistance to facilitate and promote the process aimed at strengthening the progress achieved so far in the success of its institutionalization

Classical Invariants for Principal Series and Isomorphisms of Root Data

We develop some new techniques to calculate the Schur indicator for self-dual irreducible Langlands quotients of the principal series representations. Using these techniques we derive some new formulas for the Schur indicator and the real-quaternionic indicator. We make progress towards developing an algorithm to decide whether or not two root data are isomorphic. When the derived group has cyclic center, we solve the isomorphism problem completely. An immediate consequence is a clean and precise classification theorem for connected complex reductive groups whose derived groups have cyclic center.

Strictly singular operators in pairs of L (p) space

Let E and F be Banach spaces. A linear operator from E to F is said to be strictly singular if, for any subspace Q aS, E, the restriction of A to Q is not an isomorphism. A compactness criterion for any strictly singular operator from L (p) to L (q) is found. There exists a strictly singular but not superstrictly singular operator on L (p) , provided that p not equal 2.

A functional representation of almost isometries

For each quasi-metric space X we consider the convex lattice SLip(1)(X) of all semi-Lipschitz functions on X with semi-Lipschitz constant not greater than 1. If X and Y are two complete quasi-metric spaces, we prove that every convex lattice isomorphism T from SLip(1)(Y) onto SLip(1)(X) can be written in the form Tf = c . (f o tau) + phi, where tau is an isometry, c > 0 and phi is an element of SLip(1)(X). As a consequence, we obtain that two complete quasi-metric spaces are almost isometric if, and only if, there exists an almost-unital convex lattice isomorphism between SLip(1)(X) and SLip(1) (Y).

Propuesta de un análisis metafórico-poético en una novela de ciencia ficción: 2001, una odisea del espacio

The aim of this doctoral thesis is to analyse both the text (production) and the set of cognition processes which facilitate the understanding of a masterpiece of Science Fiction: 2001, A Space Odyssey from a new perspective. Unlike other literary theories, texts in cognitive poetics (i.e. Structuralism, Generative Linguistics, Literary Criticism) are projected on the readerś minds by means of cognitive procedures. Cognitive poetics uses tools of cognitive science in order to understand literature (and in this particular case, Science Fiction). This has lead to a great change in our understanding of texts, literary and otherwise. This literary analysis was carried out on the Science Fiction genre based on the assumptions of cognitive poetics. Due to the peculiar kind of subjects touched upon by this genre, it has been theorised that the type of metaphor used for both its creation and style are rather different from other genres. Science Fiction coincides with other genres of writing in that it contains its own specific ways of providing language with a meaning while making it so innovative that many literary theories point out that it is written differently or that it is necessary to possess single reading codes in order to be fully understood. The methodology used for this thesis required a metaphorical basic and poetic conceptual analysis according to the poetical metaphor theory developed by Lakoff and Turner (1989). The aim of this metaphorical study is to analyse the basic and conceptual structure of 2001, A Space Odyssey by A. C. Clarke. The parameters of literary conceptualization of Science Fiction established by Peter Stockwell in his Poetics of Science Fiction (2000) were also applied in order to analyse this novel. The ICMs (Idealised Cognitive Models) were then examined to determine the presence of isomorphism related to the production level...

Arbitrariedade e Iconicidade na constituição dos Itens Lexicais da Libras

O presente artigo evidencia a questão da relação dos fenômenos linguísticos de arbitrariedade e iconicidade na constituição dos itens lexicais da Libras, buscando refletir possíveis mudanças, variações ou evoluções considerando o primeiro registro do dicionário iconográfico no século XIX. O registro histórico da Língua Brasileira de Sinais, doravante Libras, data do século XIX, com o dicionário iconográfico, reproduzido por Flausino José da Gama, como sendo um meio de divulgar e disseminar a língua de sinais. Após este primeiro registro outros dicionários e manuários foram elaborados visando atender distintos objetivos, ora para ensinar uma língua para os surdos, ora para estabelecer a comunicação e ora visando a integração na sociedade.  O reconhecimento da Língua Brasileira de Sinais como uma língua natural e a sua regulamentação a nível nacional é fruto do século XXI, portanto a Libras ainda tem um longo percurso investigativo nas diversas áreas a ser explorada. Na área da linguística o que nos instiga a pesquisar são os conceitos linguísticos de arbitrariedade e iconicidade, uma vez que para muitos o fato de alguns itens lexicais remeter a forma provoca uma ilusória interpretação de que todo e qualquer sinal em libras é icônico. Estes conceitos são objeto de investigação em várias línguas de sinais, tanto no oriente como no ocidente, visando uma melhor compreensão da estrutura e formação das línguas de sinais. Assim, o debate sobre iconicidade e arbitrariedade serão norteadores para nossa discussão sobre a relação destes fenômenos linguísticos na constituição da Libras.
