A educação como empoderamento na ótica do desenvolvimento: uma discussão de modelos

Apresentamos nesta comunicação uma tese de ressignificação da educação como empoderamento tendo como foco uma agenda de desenvolvimento justo, digno e inclusivo, e equacionamos os seus principais tipos ou modelos, partindo do princípio que o empoderamento, pelo facto de remeter para diversas conotações ideológicas, não permite almejar consensos quando se trata de o tomar como sinal distintivo ou imagem de marca de uma educação cuja aposta principal é a promoção de um desenvolvimento humano verdadeiramente empenhado em corresponder às expectativas normativas das pessoas em termos de justiça, respeito, dignidade, liberdade e direitos fundamentais para todos.

Perceptions of Amazonian deforestation in the British and Brazilian media

The Amazon rainforest stretches across more than six million square kilometers and nine countries. Of the original forest area it is thought that 18 per cent has been cleared, mainly for farming purposes. In Brazil, the main drivers of deforestation are beef ranching and soya production that together occupy more than 75 per cent of newly deforested land. The situation in the Amazon illustrates a fundamental dilemma facing environmentalists around the world: how to reconcile economic development with biodiversity conservation. In this paper the representation of this dilemma in the British and Brazilian news media is assessed. The results indicate that there were far more articles referring to deforestation in the Brazilian press (816 Brazilian to 29 UK) but that many of these make no mention of what factors are responsible for deforestation. The patterns of representation of the proximate (direct) causes of Amazonian deforestation were very similar in the two countries, with soya and beef cattle ranching commanding the most press attention. The ultimate (indirect) causes of deforestation, however, are treated very differently, with the Brazilian media seemingly far more aware of the role of economic development needs than the UK press. Interestingly, the role of international demand for soya, beef, and forest products in driving deforestation was highlighted primarily in the UK press. These findings are critically discussed in the context of media influence on public understandings of Amazonian deforestation.

The inverse along a product and its applications

In this paper, we study the recently defined notion of the inverse along an element. An existence criterion for the inverse along a product is given in a ring. As applications, we present the equivalent conditions for the existence and expressions of the inverse along a matrix.

School governance and academic excellence: the representations of distinguished students in an annual award of excellence

Within a research project on «academic excellence in the state school», this paper is a contribution to the sociological reflection on the cultural and organisational characteristics of the school and its relationship with the academic success of students. The data we present stem from a case study underway at a secondary school in the north of Portugal, referring to the universe of students that since 2003 have distinguished themselves for achieving grades equal to or greater than 18 (on a scale of 0 to 20) and have thus been included in the school’s Framework of Excellence. From a contextual approach to this educational practice, we focused on the cultural characteristics of the school/subject as analytical support for the study of school and non-school dimensions in their mutual connections. To this end, we used the information from document analysis and data collected from a questionnaire survey administered to more than two-thirds of the students included in the above-mentioned Framework of Excellence. Subsequently, we will use the data from this survey to understand the extent to which academic excellence is perceived as an indivisible social construction of the school’s political and organisational matrix, particularly in terms of the educational and teaching guidelines adopted by the management body. We will conclude by questioning the meaning of the school’s management policies regarding the emphasis on educational outcomes, with particular focus on the representations of excellent students in the processes of school leadership, teaching organisation, school merit and justice.

Quantum field theory approach to the optical conductivity of strained and deformed graphene

The computation of the optical conductivity of strained and deformed graphene is discussed within the framework of quantum field theory in curved spaces. The analytical solutions of the Dirac equation in an arbitrary static background geometry for one dimensional periodic deformations are computed, together with the corresponding Dirac propagator. Analytical expressions are given for the optical conductivity of strained and deformed graphene associated with both intra and interbrand transitions. The special case of small deformations is discussed and the result compared to the prediction of the tight-binding model.

Singularities of the dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field

We study the longitudinal and transverse spin dynamical structure factors of the spin-1/2 XXX chain at finite magnetic field h, focusing in particular on the singularities at excitation energies in the vicinity of the lower thresholds. While the static properties of the model can be studied within a Fermi-liquid like description in terms of pseudoparticles, our derivation of the dynamical properties relies on the introduction of a form of the ‘pseudofermion dynamical theory’ (PDT) of the 1D Hubbard model suitably modified for the spin-only XXX chain and other models with two pseudoparticle Fermi points. Specifically, we derive the exact momentum and spin-density dependences of the exponents ζτ(k) controlling the singularities for both the longitudinal  and transverse (τ = t) dynamical structure factors for the whole momentum range  , in the thermodynamic limit. This requires the numerical solution of the integral equations that define the phase shifts in these exponents expressions. We discuss the relation to neutron scattering and suggest new experiments on spin-chain compounds using a carefully oriented crystal to test our predictions.

O léxico também usa Prada? Léxico, cognição e publicidade

Se para Chomsky o léxico é um conjunto de exceções que não obedecem aos princípios normais de organização linguística, para certas visões estruturalistas é um campo onde se podem delimitar inequivocamente variadas áreas, pertencendo umas ao verdadeiro léxico da língua e outras a subgrupos que nele não se podem incluir (terminologias, antropónimos, entre outros). Partindo de um dessas áreas ou subgrupos habitualmente ignorado (as palavras que designam marcas comerciais) pretende-se apresentar uma visão integradora do léxico como rede, fazendo evidenciar a importância que a dimensão emotiva das unidades lexicais possui na respetiva estruturação global.

A Brazilian version of the "Children's Interview for Psychiatric Syndromes" (ChIPS)

OBJETIVE: The advance of research in child and adolescent psychiatry in Brazil heavily depends on the existence of instruments for the investigation of psychiatric syndromes adapted to Brazilian Portuguese. METHODS: This article describes a careful process of translation of the Children's Interview for Psychiatric Syndromes for the purpose of use in research in Brazil. The Children's Interview for Psychiatric Syndromes has a version for parents (P-ChIPs) and a version for children (ChIPS). In this article, the sections of P-ChIPS referring to attention-deficit hyperactivity disorder, oppositional-defiant disorder, conduct disorder, mania/hypomania, anorexia nervosa, bulimia nervosa and psychotic disorders were translated to Brazilian Portuguese. The sections of the ChIPS referring to substance use disorders, social anxiety disorder, specific phobias, obsessive-compulsive disorder, generalized anxiety disoder, separation anxiety disorder, post-traumatic disorders and depression/dysthimia were also adapted. Each section was translated by two independent translators and later discussed in a committee composed of experts in the field of Psychiatry and a professional of the field of linguistics. RESULT: A final version containing an interview for the main psychiatric syndromes was defined. CONCLUSION: The translated P-ChIPS is a helpful instrument in children and adolescent clinical evaluation.
