Pragmatic solutions for syntactic problems: Understanding some L2 syntactic errors in terms of discourse-pragmatic deficits

Contemporary research in generative second language (L2) acquisition has attempted to address observable target-deviant aspects of L2 grammars within a UG-continuity framework (e.g. Lardiere 2000; Schwartz 2003; Sprouse 2004; Prévost & White 1999, 2000). With the aforementioned in mind, the independence of pragmatic and syntactic development, independently observed elsewhere (e.g. Grodzinsky & Reinhart 1993; Lust et al. 1986; Pacheco & Flynn 2005; Serratrice, Sorace & Paoli 2004), becomes particularly interesting. In what follows, I examine the resetting of the Null-Subject Parameter (NSP) for English learners of L2 Spanish. I argue that insensitivity to associated discoursepragmatic constraints on the discursive distribution of overt/null subjects accounts for what appear to be particular errors as a result of syntactic deficits. It is demonstrated that despite target-deviant performance, the majority must have native-like syntactic competence given their knowledge of the Overt Pronoun Constraint (Montalbetti 1984), a principle associated with the Spanish-type setting of the NSP.

Acquisition of inflected and uninflected infinitives in child L1 European Portuguese

This study investigates the child (L1) acquisition of inflected and uninflected infinitives in European Portuguese (EP). We test and contrast properties involving two interfaces, focusing on morpho-syntactic and syntax-semantics properties of inflected infinitives, in contrast with uninflected infinitives. We present experimental results from three monolingual EP child groups, between ages 6 and 12 (n=72), compared to EP adults (n=32). Results show that children as young as 6-7 have knowledge of the morpho-syntactic properties of inflected infinitives, although at first glance they show insufficient knowledge of their syntax-semantics interface properties (i.e. non-obligatory control properties), differently from older children, who show evidence of knowledge of both types of properties. We argue that, in general, morpho-syntactic and syntax-semantics interface distinctions are also accessible to 6-7 children, but children may not show the entire range of interpretations possible for adults.

Henneguya pseudoplatystoma n. sp causing reduction in epithelial area of gills in the farmed pintado, a South American catfish: Histopathology and ultrastructure

The present study is part of an ongoing investigation into the characteristics of Myxozoan parasites of Brazilian freshwater fish and was carried out using morphology, histopathology and electron microscopy analysis. A new Myxosporea species (Henneguya pseudoplatystoma) is described causing an important reduction in gill function in the farmed pintado (a hybrid fish from a cross between Pseudoplatystoma corruscans and Pseudoplatystoma fasciatum), which is a commercially important South American catfish. From a total of 98 pintado juveniles from fish farms in the states of Sao Paulo and Mato Grosso do Sul (Brazil), 36 samples (36.7%) exhibited infection of the gill filaments. infection was intense, with several plasmodia occurring on a same gill filament. The plasmodia were white and measured up to 0.5 mm in length; mature spores were ellipsoidal in the frontal view, measuring 33.2 +/- 1.9 mu m in total length, 10.4 +/- 0.6 mu m in body length, 3.4 +/- 0.4 mu m in width and 22.7 +/- 1.7 mu m in the caudal process. The polar capsules were elongated, measuring 3.3 +/- 0.4 mu m in length and 1.0 +/- 0.1 mu m in width and the polar filaments had six to seven turns. Histopathological analysis revealed the parasite in the connective tissue of the gill filaments and lamella. No inflammatory process was observed, but the development of the plasmodia reduced the area of functional epithelium. Ultrastructural analyses revealed a single plasmodial wall, which was in direct contact with the host cells and had numerous projections in direction of the host cells as well as extensive pinocytotic canals. A thick layer (2-6 mu m) of fibrous material and numerous mitochondria were found in the ectoplasm. Generative cells and the earliest stage of sporogenesis were seen more internally. Advanced spore developmental stages and mature spores were found in the central portion of the plasmodia. (C) 2009 Elsevier B.V. All rights reserved.

Prosodic Morphology : Gender in Arabic Perfect Active and Passive 3rd Person Singular Verbs

Prosodic /template Morphology, that "draws heavily on the theoretical apparatus and formalisms of the generative phonology model known as autosegmental phonology" (Katamba, F. 1993: 154), is the best analysis that can handle Arabic morphology. Verbs in Arabic are represented on three independent tiers: root tier, the skeletal tier and the vocalic melody tier (Katamba, F. 1993). Vowel morphemes, which are represented by diacritics, are inserted within the consonant morphemes, which are represented by primary symbols, to form words. The morpheme tier hypothesis paves the way to understand the nonconcatenative Arabic morphology. This paper analyzes gender in perfect active and passive 3rd person singular verbs on the basis of PM. The focus of the analysis shall be drawn heavily on the most common Arabic verbs; triconsonantal verbs, with brief introduction of the less common verbs; quadriconsonantal perfect active and passive masculine and feminine 3rd person singular verbs. I shall, too, cast the light on some vowel changes that some verbs undergo when voice changes.

Literatura infantil : uma abordagem das qualidades sensíveis e inteligíveis da leitura imagética na escola

Esta dissertação discute a leitura de textos imagéticos a partir da perspectiva da educação e da semiótica visual, tratando das articulações e relações entre os elementos constitutivos da imagem em livros de literatura infantil sem texto verbal. A investigação busca revelar, na complexidade das relações existentes entre elementos estruturantes das imagens nos livros O caminho do caracol e Cena de rua, o sentido que se inscreve no texto e a possibilidade da sua leitura no meio escolar. As obras literárias para a infância veiculam a linguagem visual em junção com a verbal e propiciam experiências sensíveis e inteligíveis. A partir da teoria semiótica greimasiana, aplicando instrumentos de análise do percurso gerativo de sentido, a pesquisa demonstra que o texto imagético é estruturado por diferentes níveis de complexidade, impondo um modo de ler específico. A identificação, descrição, classificação, bem como as relações entre as categorias, nas suas dimensões cromática, eidética e topológica, levam à constatação que as qualidades plásticas da imagem organizam sistemas de linguagem, reunindo solidariamente o plano da expressão e do conteúdo, criam estruturas e geram efeitos de sentido. A imagem, então, constitui-se como objeto de significação e a ilustração presente no livro de literatura infantil, ao ser tratada como texto lisível, torna-se objeto de leitura. A complexidade desse tipo de texto aponta a necessidade da formação específica de professores para explorar a leitura escolar das linguagens visuais.

A linguagem de Oscar Niemeyer

Este trabalho tem como objetivo a descrição dos elementos que caracterizam a singularidade da linguagem arquitetônica de Oscar Niemeyer. Argumenta que a identificação de tais elementos passa pelo escrutínio de aspectos não visíveis da obra do arquiteto. A identificação foi possível a partir da análise de edifícios caracterizados pelo perfil curvilíneo e da construção de um modelo que associa os elementos compositivos utilizados por Niemeyer a uma Gramática de Formas. A utilização do modelo possibilitou revelar os princípios generativos - conjunto de regras, vocabulário e relações geométricas – que caracterizam o estilo – ou linguagem arquitetônica de Niemeyer. Ajudou ainda a demonstrar como a linguagem de Niemeyer associa de forma original, operações de transformação como rotação, reflexão, e translação a um vocabulário de curvas. A associação é parametrizada segundo um traçado regulador baseado na seção áurea. Em suas conclusões o trabalho sugere possibilidades de desenvolvimento desta gramática para todas as figuras utilizadas por Niemeyer e a aplicação de princípios generativos no ensino de arquitetura.

Uma interpretação psicogenética da moda

Este trabalho objetiva estudar a imagem corporal estabelecida pela cultura, mais especificamente, pela Moda, através da gênese de suas variantes, visando atingir os eixos invariantes psicoantropológicos que constituem-se nas grandes categorias lógico-generativas, as quais formam a sua estrutura subjacente constante. Visa-se estabelecer a relação entre o sistema psicológico definido pelo corpo como a entidade que ultrapassa o nível biológico e o sistema de comunicação interpessoal e social. Na interconecção do corpo e da comunicação social, surge a Moda em que a realidade corporal constitui-se em um alicerce para os signos sociais e psicológicos. Para tal, desdobrou-se o sistema de trocas da linguagem, sugerido por Levi-Strauss, em verbal e não-verbal, considerando a comunicação efetuada pela imagem corporal como modalidade da segunda. Utilizando o método estruturalista, tentou-se transpor os conceitos da linguística de Ferdinand de Saussure para o campo da imagem corporal, sincronica e diacronicamente configurada. Foi estabelecido, ainda, a respectiva principal categoria invariante, composta por eixo bipolar: a identidade e a diferenciação, semanticamente preenchidos por fatores afetivos e culturais.

Escola : da magia da criação : as éticas que sustentam a escola pública

Esta tese procura mostrar como a Escola Pública consegue recriar-se e permanecer apesar dos antagonismos e problemas que a consomem indefinidamente. Ela resulta de um estudo de caso, desenvolvido na Escola Estadual de Ensino Médio Bandeirante de Guaporé, (RS-Brasil), nos anos de 2000 a 2004. A partir de uma perspectiva sócio-antropológica, ancorada em aportes teóricos de Georges Balandier, Edgar Morin, Michel Maffesoli e Humberto Maturana, o pesquisador utilizou-se dos meios e técnicas conferidos pelo método etnográfico de pesquisa para investigar os movimentos de ordem, desordem, organização e mudança na Escola, buscando enfocar os vitalismos que a perpassam e lhe dão jovialidade. Pela observação reflexiva, registrada em diário de campo, procurou perceber nas ações de conduta, comportamentos, posturas e atitudes dos sujeitos o fluir das emoções, geradoras das éticas que perpassam as relações, bem como as ambigüidades de sua manifestação. Por meio de entrevistas, com amostras selecionadas de professores, pais, alunos e funcionários, investigou as razões e motivações de suas presenças na Escola, bem como as qualidades, sabores e dissabores por eles produzidos na convivência. Pôde conferir que, como organismo vivo, a Escola pública se configura em teias de relações onde magia, criação e sentidos encontram espaço de manifestação nos prazeres que a convivência produz.É nesta Estética do Estar-Juntos que o autor percebeu a fonte inesgotável das Éticas que se transfiguram nos encontros, reencontros e relações e que possibilitam a Escola auto-organizar-se e recriar-se constantemente, produzindo os liames de sua e sustentação e permanência, apesar do turbilhão que a consome.

A expressão do FOXP2 : uma introdução ao estudo das relações entre genes e linguagem

A aquisição da linguagem é um processo invariavelmente dependente da exposição ao ambiente. Contudo, a mais famosa e controversa hipótese desenvolvida por Chomsky sustenta que a criança traz para o processo de aprendizagem da língua um conjunto de recursos específicos – a Gramática Universal – para superar a pobreza de estímulos do ambiente e construir uma gramática final adequada, composta por princípios universais e parâmetros fixados de acordo com a experiência na comunidade lingüística. A Gramática Universal é, assim, entendida como uma dotação genética, necessária, mas não suficiente, para a aquisição da linguagem. Para além da hipótese do inatismo – central à tradição gerativista – a relação entre genes e linguagem vem sendo investigada há muitos anos, com evidências significativas de transmissão hereditária e etiologia genética para diversos tipos de distúrbios de linguagem. Mais recentemente, em 2001, foi descoberto o primeiro caso de um gene, o FOXP2, implicado na habilidade de adquirir e desenvolver a fala e a linguagem. Este trabalho parte de uma introdução ao processo de aquisição da linguagem em uma perspectiva inatista (Capítulo I) para enfocar os aspectos centrais à organização biológica da faculdade da linguagem (Capítulo II), propondo, a partir da análise dos efeitos da mutação do gene FOXP2, uma discussão introdutória sobre como o estudo dos distúrbios do desenvolvimento da linguagem, avaliados a partir de suas características fenotípica e genotípica, pode contribuir para a exploração de questões fundamentais acerca do desenvolvimento lingüístico e cognitivo (Capítulo III).

Era um sonho desde criança : a representação social da docência para os professores do município de Queimadas-PB

The objective of this work was to access and understand the teaching social representation (MOSCOVICI, 2005) for the teachers of the children education and fundamental education at Queimadas city, Paraíba. We assume that one representation that allows the teacher to name its profession and to act on it, is a derivative of regularities that are expressed by means of a habitus (BOURDIEU, 1983a), generative matrix of perception and action. This teaching habitus is originated from the experiences and the trajectories of social and professional life of the group. Therefore, from some variables, we tried to access the profile of the group of teachers studied and to get closer of their life style to understand their profession choice and the teaching social representation for this group. In this research, it was used four data sources: a) the questionnaires of characterization; b) the questionnaires of practices and meanings; c) the experience reports and; d) the interviews in depth. The analysis of the data collected was done by means of the simple statistics (frequency), the intersection of variables through cross tables and, the thematic analysis of the contents. The results show that there is a lightly homogeneous group in terms of its social origin and its life style, moreover, they conduct to an overlap between this origin/style and the professional choice. On the other hand, the teacher representation is multi-dimensional such that, all dimensions intercept and articulate with each other to provide a concise teacher representation. They are four dimensions: love and care, help and donation, teaching and learning and, sacrifice and hope. The elements of the teacher representation are substantiated in the schemes of perception and appreciation of the group, in the regularities and life experiences in the context of religion, family, gender and profession. In these regularities we find the elements that comprise the teaching habitus which drives perception and action, representation and daily practice of these teachers. The teaching social representation is still perceived as a threshold for the professional identity of the group of teachers considered. We also observed that there are signs of changes in the practices used by these professionals since they graduate from the course of pedagogy. However, it is not possible to say that these changes are isolated or they lead to a transformation in the teaching habitus or the teaching social representation

Identificação de crianças e adolescentes com suspeita de câncer: uma proposta de intervenção

Unlike adult cancer, where cells usually originate from epithelial tissue and is linked to environmental factors, malignant tumors in childhood are mostly of embryonic origin and have a phase of rapid proliferation. When not started chemotherapy at this stage, the tumor increases in size, reducing their growth rate, thus reducing the response to chemotherapy. Childhood cancer is in Brazil, the second cause of mortality among children and adolescents from one to nineteen. His impact on the ranking of diseases becomes significantly important to public health since the first issue is related to accidents and violence. Many children are still sent to the centers of high complexity for cancer treatment with advanced stage disease. The delay in referral to diagnosis can be family, or the difficulty of access to the health sector, or the characteristics of the disease and lack of health staff regarding theme of childhood cancer. Before this problem, we aimed to assess the performance of health teams in the identification of child and adolescent symptoms of cancer in primary care, through the action research methodology, which includes the teaching-learning, seminars, describing the actions of the group and discussing the activities after the training. This study involved thirty-seven health professionals who provide care for children and adolescents in the USF Felipe Shrimp II, the Support Center for Children with Cancer and the pediatric hospital UFRN during the period from March to December 2010. The data were analyzed simultaneously to evaluate actions, following the direction of the analysis of ideas Freires, having as theoretical reference the primary health care. The diagnosis of current reality, as knowledge of the health team targeted for early identification of signs and symptoms raised through questioning, presented as generative themes: resistance to change, awareness of the need for apprehension of knowledge; prior knowledge through the media, fragmentation of the healthcare network, interfering with the operation of the reference and counter, the stigma of death, among others. The selected themes enabled the choice of content for the preparation of four seminars, such as implementation of collective action for discussion problematical. The teaching-learning process has allowed the study participants awareness of the problem and work through the knowledge acquired by interfering in decreasing the time interval between the identification of signs and symptoms of cancer and early specialist treatment. Their difficulties we are faced with a diagnosis of terminal cancer and associated with delayed access to laboratory tests and imaging necessary for the diagnosis of neoplasms. Thus, we find that when the team is consciously involved in the education process from identification of the problem situation, there may be significant changes in daily activities through awareness of being. However, we also realize that acquisition of knowledge and interest of the team are not enough, since to be efficiency of our service, we need an organization of cancer care network operating in the state of Rio Grande do Norte

Estudo do efeito de substratos metamateriais em parâmetros de antenas de microfita

Microstrip antennas are subject matter in several research fields due to its numerous advantages. The discovery, at 1999, of a new class of materials called metamaterials - usually composed of metallic elements immersed in a dielectric medium, have attracted the attention of the scientific community, due to its electromagnetic properties, especially the ability to use in planar structures, such as microstrip, without interfering with their traditional geometry. The aim of this paper is to analyze the effects of one and bidimensional metamaterial substrates in microstrip antennas, with different configurations of resonance rings, SRR, in the dielectric layer. Fractal geometry is applied to these rings, in seeking to verify a multiband behavior and to reduce the resonance frequency of the antennas. The results are then given by commercial software Ansoft HFSS, used for precise analysis of the electromagnetic behavior of antennas by Finite Element Method (FEM). To reach it, this essay will first perform a literature study on fractal geometry and its generative process. This paper also presents an analysis of microstrip antennas, with emphasis on addressing different types of substrates as part of its electric and magnetic anisotropic behavior. It s performed too an approach on metamaterials and their unique properties

Objetivos e conteúdos no ensino de física para adultos: um estudo de caso

The dissertation presents the learning, production and results of a study with a group of adult students of a high school level class in a night time public school at the Zona Oeste district of Natal-RN. As a teacher of Physics of these adult students, whose age is between 17 and 65 years, we felt the need to deepen our knowledge about the specifics of these students and build ways of teaching which would lead to a more significant educational process beside them. Among these ways of teaching, we emphasize, first, the performance of an extra-class activity that triggered the students' oral narratives about their life stories. Such narratives have led us to prioritize, as goals of teaching: socialization and the rescue of the search for a permanent learning, self-esteem and skills development to promote the exercise of autonomy. The students' previous contacts with the country life showed to be extremely significant for their memories and motives, suggesting the theme "Nature" to be adopted as a matrix for generative themes to be adopted during the teaching and learning moments with them. Considering these results, we construct a teaching proposal for continued work with the class, with which we chose the "Climate" as a guiding theme of this proposal, here presented and analyzed. In addition to a movement between problematizations developed in a thematic framework - through the initial questions of the students -, and those in a more conceptual approach - that we induced -, we have adopted as central methodological aspect the use of oral and written language, both as an exercise of dialogue, Freire's perspective, such as a structural element of cognitive processes, the perspectives of Vygotsky and Bakhtin. The development of the proposal was registered by audio and teacher and students´ regular written records, for 1 month and a half. As positive outcomes of the proposal, we emphasize the changing attitudes of students, showing a significant increase of their initiative in participating of the classes, besides a creative and critical use of arguments during the situations studied
