Este estudo teve a finalidade de descrever, num corpus literário de iniciação, tanto a metáfora conceptual e suas manifestações lingüísticas quanto à intertextualidade, como caminhos possíveis para um processo de compreensão construtivo e autônomo, em textos de língua portuguesa produzidos em culturas diferentes. Selecionamos, como material de investigação dos aspectos estudados, na literatura brasileira, uma trilogia metaliterária de Lygia Bojunga Nunes, na literatura portuguesa, dois contos de Sophia de Mello Breyner Andresen, e na literatura africana, optamos pela representação moçambicana com uma novela de Mia Couto. As obras das duas primeiras autoras são lidas por jovens entre 14 a 17 anos nos seus países de origem e a obra de Mia Couto está aqui relacionada por ser uma possibilidade e um enriquecimento para o leitor em formação. Trabalhamos com a metáfora inserida nos fundamentos da Semântica cognitiva, porque traz como preceito básico o desvelamento das associações que vão embasar nossos esquemas mentais e cujo conhecimento vai-nos habilitando a uma autonomia para relacionar sentidos e perceber que até a mais obscura emissão vai ganhar ares de previsibilidade por conta das nossas experiências, dos textos que buscamos na memória e do contexto que construímos com os dados lingüísticos que preenchem a moldura de um dado cenário. A metáfora, porém, se mostrou produtiva em nossas análises porque associamos a sua gênese conceptual com a sua função pragmática. É nessa fusão que ela se faz língua, se faz pujante, desviante e revela para o interlocutor as marcas que a remetem para a circularidade original, ou seja, o conceito da qual ela foi gerida. Verificamos, na aplicação da teoria no corpus analisado, que, através dos fundamentos da metáfora conceptual e da intertextualidade, podemos compreender o que é universal e o que é cultural nas nossas expressões literárias e que a fronteira entre essas duas dimensões não fratura o diálogo que se faz urgente e necessário, para a defesa de uma cultura lusófona

After stroke, white matter integrity can be affected both locally and distally to the primary lesion location. It has been shown that tract disruption in mirror's regions of the contralateral hemisphere is associated with degree of functional impairment. Fourteen patients suffering right hemispheric focal stroke (S) and eighteen healthy controls (HC) underwent Diffusion Weighted Imaging (DWI) and neuropsychological assessment. The stroke patient group was divided into poor (SP; n = 8) and good (SG; n = 6) cognitive recovery groups according to their cognitive improvement from the acute phase (72 hours after stroke) to the subacute phase (3 months post-stroke). Whole-brain DWI data analysis was performed by computing Diffusion Tensor Imaging (DTI) followed by Tract Based Spatial Statistics (TBSS). Assessment of effects was obtained computing the correlation of the projections on TBSS skeleton of Fractional Anisotropy (FA) and Radial Diffusivity (RD) with cognitive test results. Significant decrease of FA was found only in right brain anatomical areas for the S group when compared to the HC group. Analyzed separately, stroke patients with poor cognitive recovery showed additional significant FA decrease in several left hemisphere regions; whereas SG patients showed significant decrease only in the left genu of corpus callosum when compared to the HC. For the SG group, whole brain analysis revealed significant correlation between the performance in the Semantic Fluency test and the FA in the right hemisphere as well as between the performance in the Grooved Pegboard Test (GPT) and theTrail Making Test-part A and the FA in the left hemisphere. For the SP group, correlation analysis revealed significant correlation between the performance in the GPT and the FA in the right hemisphere.

[EN] The goal of this contribution is twofold: on the one hand, to review two relatively recent contributions in the field of Eskimo-Aleut historical linguistics in which it is proposed that Eskimo-Aleut languages are related genealogically to Wakashan (Holst 2004) and?/or Nostratic (Krougly-Enke 2008). These contributions can be characterized by saying that their authors have taken little care to be diligent and responsible in the application of the comparative method, and that their familiarity with the languages involved is insufficient. Eskimo-Aleut languages belong to a very exclusive group of language families that have been (and still are) used, sometimes compulsively, in the business of so-called “long-range comparisons”. Those carrying out such studies are very often unaware of the most basic facts regarding the philological and linguistic traditions of those languages, as a result of what mountains of very low quality works with almost no-relevancy for the specialist grow every year to the desperation of the scientific community, whose attitude toward them ranges from the most profound indifference to the toughest (and most explicit) critical tone. Since Basque also belongs to this group of “compare-with-everything-you-come- across” languages, it is my intention to provide the Basque readership with a sort of “pedagogical case” to show that little known languages, far from underrepresented in the field, already have a very long tradition in historical and comparative linguistics, i.e. nobody can approach them without previous acquaintance with the materials. Studies dealing with the methodological inappropriateness of the Moscow School’s Nostratic hypothesis or the incorrectness of many of the proposed new taxonomic Amerindian subfamilies (several of them involving the aforementioned Wakashan languages), that is to say, the frameworks on which Krougly-Enke and Holst work, respectively, are plenty (i.a. Campbell 1997: 260-329, Campbell & Poser 2008: 234-96), therefore there is no reason to insist once more on the very same point. This is the reason why I will not discuss per se Eskimo-Aleut–Wakashan or Eskimo-Aleut–Nostratic. On the contrary, I will focus attention upon very concrete aspects of Krougly-Enke and Holst´s proposals, i.e. when they work on “less ambitious” problems, for example, dealing with the minutiae of internal facts or analyzing certain words from the sole perspective of Eskimo-Aleut materials (in other words, those cases in which even they do not invoke the ad hoc help of Nostratic stuff). I will try to explain why some of their proposals are wrong, demonstrate where the problem lies, and fix it if possible. In doing so, I will propose new etymologies in an attempt at showing how we may proceed. The main difference between this and handbook examples lies in the reality of what we are doing: this is a pure etymological exercise from beginning to end. I will try to throw a bit of light on a couple of problematic questions regarding Aleut historical phonology, demonstrating how much work should be done at the lowest level of the Eskimo-Aleut pyramid; it is technically impossible to reach the peak of the pyramid without having completed the base. As far as Aleut is regarded, I will mainly profit not only from the use of the traditional philological analysis of Aleut (and, eventually, of Eskimo) materials, but also of diachronic typology, bringing into discussion what in my opinion seems useful, and in some cases I think decisive, parallels. It is worth noting that this paper makes up yet another part of a series of exploratory works dealing with etymological aspects of the reconstruction of Proto-Eskimo-Aleut, with special emphasis on Aleut (vid. i.a. Alonso de la Fuente 2006/2007, 2008a, 2008b, 2010a), whose main goal is to become the solid basis for an etymological dictionary of the Aleut language, currently in progress.

Background: In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the efficacy of a cognitive-behavioural psychological intervention, delivered by primary care psychologists in patients with mixed anxiety-depressive disorder compared to usual care. Methods/Design: This is an open-label, multicentre, randomized, and controlled study with two parallel groups. A random sample of 246 patients will be recruited with mild-to-moderate mixed anxiety-depressive disorder, from the target population on the lists of 41 primary care doctors. Patients will be randomly assigned to the intervention group, who will receive standardised cognitive-behavioural therapy delivered by psychologists together with usual care, or to a control group, who will receive usual care alone. The cognitive-behavioural therapy intervention is composed of eight individual 60-minute face-to face sessions conducted in eight consecutive weeks. A follow-up session will be conducted over the telephone, for reinforcement or referral as appropriate, 6 months after the intervention, as required. The primary outcome variable will be the change in scores on the Short Form-36 General Health Survey. We will also measure the change in the frequency and intensity of anxiety symptoms (State-Trait Anxiety Inventory) and depression (Beck Depression Inventory) at baseline, and 3, 6 and 12 months later. Additionally, we will collect information on the use of drugs and health care services. Discussion: The aim of this study is to assess the efficacy of a primary care-based cognitive-behavioural psychological intervention in patients with mixed anxiety-depressive disorder. The international scientific evidence has demonstrated the need for psychologists in primary care. However, given the differences between health policies and health services, it is important to test the effect of these psychological interventions in our geographical setting.

Despite advances in neonatal care, hypoxic-ischemic brain injury is still a serious clinical problem, which is responsible for many cases of perinatal mortality, cerebral palsy, motor impairment and cognitive deficits. Resveratrol, a natural polyphenol with important anti-oxidant and anti-inflammatory properties, is present in grapevines, peanuts and pomegranates. The aim of the present work was to evaluate the possible neuroprotective effect of resveratrol when administered before or immediately after a hypoxic-ischemic brain event in neonatal rats by analyzing brain damage, the mitochondrial status and long-term cognitive impairment. Our results indicate that pretreatment with resveratrol protects against brain damage, reducing infarct volume, preserving myelination and minimizing the astroglial reactive response. Moreover its neuroprotective effect was found to be long lasting, as behavioral outcomes were significantly improved at adulthood. We speculate that one of the mechanisms for this neuroprotection may be related to the maintenance of the mitochondrial inner membrane integrity and potential, and to the reduction of reactive oxygen species. Curiously, none of these protective features was observed when resveratrol was administered immediately after hypoxia-ischemia.

Este estudo investiga a Matriz de Referência e 117 itens de provas de Linguagens, Códigos e suas Tecnologias, do Exame Nacional do Ensino Médio (Enem), no período compreendido entre 2009 e 2013, a fim de se estabelecerem relações entre os enunciados de comando dos itens e as ações requeridas do participante, focalizando-se especialmente os processos verbais. A leitura do material teórico-metodológico que constitui o Enem revela uma visão sociointeracionista de língua, centrada no desenvolvimento de competências e habilidades que levarão o aluno ao domínio da língua, importante fator de representação e inclusão social. Por extensão, tal concepção permite compreender a prova do Enem como um ato de interação entre o agente público organizador e os participantes do exame. Como principal referencial teórico, elegeu-se a Linguística Sistêmico-Funcional (HALLIDAY; MATTHIESSEN, 2004), enfocando-se especialmente a metafunção ideacional do sistema de transitividade, por ser ela a reveladora da experiência e da representação de mundo, sendo capaz, portanto, de expressar os sentidos de aprendizagem linguística e de ação por meio da língua materna/linguagem. Dois objetivos orientaram este estudo. O objetivo específico consistiu em verificar a relação entre os processos verbais mais recorrentes na Matriz e nos itens analisados, a fim de compreender a relação entre o comando do item e a ação de um cidadão letrado, competente e hábil para a produção e recepção de textos em língua materna. Como objetivo geral, espera-se que este estudo possa contribuir para o ensino da Língua Portuguesa, a partir da análise e das reflexões desenvolvidas. Percorreu-se do suporte legal que dá origem ao Enem à configuração do item como um gênero textual para, então, passar-se ao exame do corpus. O exame da Matriz de Referência para a área de Linguagens, Códigos e suas Tecnologias e dos itens selecionados apontou a predominância de processos materiais, mentais e relacionais nos enunciados de comando, que, por sua vez, deflagram ações mentais cognitivas nos participantes. Esse resultado indica que dominar a língua para atuar na sociedade com autonomia e competência implica, principalmente, a mobilização interna e intelectual do indivíduo, com base em seus conhecimentos e reflexões.

Technology roadmapping workshops are essentially a social mechanism for exploring, creating, shaping and implementing ideas. The front-end of a roadmapping session is based on brainstorming in order to tap into the group's diverse knowledge. The aim of this idea stimulation activity is to capture and share as many perspectives as possible across the full scope of the area of interest. The premise to such group brainstorming is that the sharing and exchange of ideas leads to cognitive stimulation resulting in a greater overall group idea generation performance in terms of the number, variety and originality of ideas. However, it must be recognized that the ideation stage in a roadmapping workshop is a complex psychosocial phenomenon with underlying cognitive and social processes. Thus, there are downsides to group interactions and these must be addressed in order to fully benefit from the power of a roadmapping workshop. This paper will highlight and discuss the key cognitive and social inhibitors involved. These include: production blocking, evaluation apprehension, free riding/social loafing, low norm setting/matching. Facilitation actions and process adjustments to counter such negative factors will be identified so as to provide a psychosocial basis for improving the running of roadmapping workshops. © 2009 PICMET.

The purpose of this study is to develop a model of cognitive impairment to help designers consider the range of issues which affect the lives of people living with such impairment. A series of interviews with experts of cognitive impairment was conducted to describe and assess the links between specific medical conditions, including learning disability, specific learning difficulties, autistic spectrum disorders, traumatic brain injury and schizophrenia, and the types of cognitive impairment associated with them. The results reveal some of the most prevalent and serious types of impairment, which - when transformed into design guidance - will help designers make mainstream products more inclusive also for people with cognitive impairment. © 2011 Springer-Verlag.
