Gramáticas pós-NGB: do discurso oficial a outros discursos (im)possíveis

A implementação da Nomenclatura Gramatical Brasileira (NGB) em 1959 e a assunção da Linguística no Brasil na década de 60 são acontecimentos que provocaram profundas mudanças no fazer gramatical. A NGB, enquanto acontecimento discursivo, ao evidenciar determinados termos e silenciar outros, reestrutura a memória do discurso gramatical brasileiro, regulando a relação do sujeito com o dizível e instaurando uma nova formação discursiva dominante, a qual se sobrepôs às formações discursivas anteriores. No presente trabalho, partimos do pressuposto de que, apesar do efeito da censura imposta pela terminologia oficial, o discurso gramatical produzido após a sua instituição é constitutivamente da ordem do heterogêneo. Assim sendo, com base no aporte teórico da Análise de Discurso de Pêcheux e Orlandi e nos estudos do projeto História das Ideias Linguísticas, investigamos o funcionamento do discurso legitimado pela NGB nas gramáticas cuja publicação a sucederam, mais especificamente em sete gramáticas publicadas entre 1959 e 1969. Interessa-nos, portanto, com vistas a depreender a forma como se materializa a tensão entre os sentidos oficiais e os sentidos censurados, desnaturalizar o processo de (re)significação dos termos acolhidos pela NGB, depreendendo, assim, como os sentidos silenciados se fizeram significar na materialidade linguística das gramáticas

As orações subordinadas não classificadas pela NGB agente da passiva modal - locativa

As orações subordinadas agente da passiva, as orações modais e as locativas têm pleno funcionamento na língua portuguesa, embora não tenham seu reconhecimento na Nomenclatura Gramatical Brasileira, o que significa dizer que estas orações não existem, oficialmente, na nossa língua. Este trabalho tem por objetivo demonstrar como este tema é desenvolvido entre os autores de língua portuguesa, entre gramáticos tradicionais, funcionalistas e pedagógicos e sintaticistas e, principalmente, que estas orações são normalmente utilizadas, tanto na língua falada como na escrita. Realizou-se um estudo comparado entre 21 renomados autores de língua portuguesa, em uma detalhada revisão de literatura. Destarte contribui-se para ampliação da pesquisa na área da sintaxe portuguesa a fim de promover uma reflexão aprofundada sobre o tema entre os estudiosos da língua portuguesa ou entre os que, de alguma forma, se interessam pelo nosso idioma. Mas o que importa mesmo como resultado da pesquisa é comprovar o pleno funcionamento destas orações no idioma em movimento, na língua viva. Para tal, compôs-se um pequeno corpus por meio de textos midiáticos. Foram selecionados sessenta recortes dos jornais O Globo, JB e das revistas Veja e CartaCapital, todos on line, que comprovam o uso natural, ou mesmo comum, das orações agente da passiva, das orações modais e locativas. Assim tornou-se possível afirmar que estas orações funcionam plenamente em nosso idioma, encontram, na sintaxe portuguesa, seu habitat natural e ganham vida, graça e força na fala e na escrita dos falantes de língua portuguesa, na nossa fala e na nossa escrita, de nós, brasileiros

O legado grego na terminologia gramatical brasileira

This study aims at investigating the existence of a Greek terminological legacy in the Brazilian grammatical organization, taking into account that the initial Greek grammar is the source of our grammar, through the Latin grammar, and that the field defined by it is a reference point for studying the evolution of Western thought about language. The theoretical and methodological approach is based on Historical Linguistics along the lines that guided the extensive research on the emergence of grammar in the West, which is the source of the information organized here (NEVES, 2005). The reflections focus on the examination of nomenclature, considering that it conceptually maps the set of positions assumed, and in general maintained, that deserve consideration. Among other things, the survey compared both Greek terms inherited in the continuous current of the grammatical thinking with Greek terms introduced later, and terms transliterated from the Greek with terms modeled on the Latin translation. In addition, there have been cases of names that were changed while the concept was kept and cases of concepts that were changed while the name was kept. Anyway, the examination of the nomenclature reveals the undeniable existence of a Greek legacy in the organization of the Portuguese grammar.

Heritage speaker competence differences, language change and input type: inflected infinitives in Heritage Brazilian Portuguese

It has been argued that colloquial dialects of Brazilian Portuguese (BP) have undergone significant linguistic change resulting in the loss of inflected infinitives (e.g., Pires, 2002, 2006). Since BP adults, at least educated ones, have complete knowledge of inflected infinitives, the implicit claim is that they are transmitted via formal education in the standard dialect. In the present article, I test one of the latent predictions of such claims; namely, the fact that heritage speakers of BP who lack formal education in the standard dialect should never develop native-like knowledge of inflected infinitives. In doing so, I highlight two significant implications (a) that heritage speaker grammars are a good source for testing dialectal variation and language change proposals and (b) incomplete acquisition and/or attrition are not the only sources of heritage language competence differences. Employing the syntactic and semantic tests of Rothman and Iverson (2007), I compare heritage speakers' knowledge to Rothman and Iverson's advanced adult L2 learners and educated native controls. Unlike the latter groups, the data for heritage speakers indicate that they do not have target knowledge of inflected infinitives, lending support to Pires' claims, suggesting that literacy plays a significant role in the acquisition of this grammatical property in BP.

Structural characterization of a new acylpolyaminetoxin from the venom of Brazilian garden spider Nephilengys cruentata

Mario Sergio Palma, Yasuhiro Itagaki, Tsuyoshi Fujita, Hideo Naoki and Terumi Nakajima. Structural characterization of a new acylpolpaminetoxin from the venom of Brazilian garden spider Nephilengys: cruentata. Toxicon 36, 455-493, 1998.-The use of mass spectrometry, in which high-energy CID and charge remote fragmentation both of protonated and sodium-attached molecular ions was applied, afforded the structural elucidation of a new acylgolyaminetoxin with M-W= 801 da from the venom of the Brazilian garden spider Nephilengys cruentata. In spite of having the same M-W of the NPTX-2, previously described in the venom of the Joro spider Nephila clavata, neither toxins are isomers. In order to differentiate them by using the most usual nomenclature, the new toxin was named NPTX-801C and the NPTX-2 was renamed to NPTX-801E. Both toxins have as common structure the 4-hydroxyindole-3-acetyl-asparaginyl-cadaveryl moiety in their molecules and their structure may be represented in a simplified way: NPTX-801E is HO-indole-Asn-Cad-Pta-Orn-Arg and NPTX-801C is HO-indole-Asn-Cad-Gly-Put-Pta-Pta.

HLA-DR in Brazilian patients with polyarteritis nodosa (PAN) and microscopic polyangiitis (MPA)

The aim of this study was to evaluate the frequency and clinical associations of HLA-DR alleles in Brazilian Caucasian patients with polyarteritis nodosa (PAN) or microscopic polyangiitis (MPA). We evaluated 29 Caucasian patients with vasculitis classified as PAN or MPA according to the American College of Rheumatology (ACR) 1990 Criteria, Chapel Hill Consensus Conference (CHCC) nomenclature for vasculitis and EULAR recommendations for conducting clinical studies in systemic vasculitis. HLA-DR alleles were typed using polymerase chain reaction-amplified DNA, hybridized with sequence-specific low resolution primers. DNA obtained from 59 Caucasian healthy blood donors were used as control. In order to evaluate if a specific HLA may have influence on the clinical profile of those diseases, we also divided the patients according to Birmingham vasculitis score (BVAS) and Five-Factors Score (FFS) at the time of diagnosis. Increased frequency of HLA-DRB1*16 (p = 0.023) and DRB4*01 (p = 0.048) was found in patients with higher disease activity at the time of diagnosis (BVAS >= 22). Patients with less severe disease (FFS = 0) had a higher frequency of HLA-DRB1*03 (p = 0.011). Patients with gastrointestinal tract involvement had significantly increased frequency of HLA-DRB1*11 or B1*12 (p = 0.046), B1*13 (p = 0.021) and B3 (p = 0.008). In contrast, patients with renal disease, had higher frequency of DRB1*15 or DRB1*16 (p = 0.035) and B5 (p = 0.035). In the subgroup of patients with MPA, increased frequency of HLA-DRB1*15 was found in patients with BVAS >= 22 (p = 0.038) and FFS >= 1 (p = 0.039) suggesting that this allele is associated with more aggressive disease. Antineutrophil cytoplasmic antibodies (ANCA) negative MPA patients had significantly increased frequency of HLA-DRB1*11 or DRB1*12 when compared to ANCA positive patients (p = 0.023). Our results suggest that HLA-DR alleles may influence PAN and MPA clinical expression and outcome and that in MPA they participate in the mechanisms involved in the development to ANCA.

Soil Carbon Turnover Measurement by Physical Fractionation at a Forest-to-Pasture Chronosequence in the Brazilian Amazon

The effect of conversion from forest-to-pasture upon soil carbon stocks has been intensively discussed, but few studies focus on how this land-use change affects carbon (C) distribution across soil fractions in the Amazon basin. We investigated this in the 20 cm depth along a chronosequence of sites from native forest to three successively older pastures. We performed a physicochemical fractionation of bulk soil samples to better understand the mechanisms by which soil C is stabilized and evaluate the contribution of each C fraction to total soil C. Additionally, we used a two-pool model to estimate the mean residence time (MRT) for the slow and active pool C in each fraction. Soil C increased with conversion from forest-to-pasture in the particulate organic matter (> 250 mu m), microaggregate (53-250 mu m), and d-clay (< 2 mu m) fractions. The microaggregate comprised the highest soil C content after the conversion from forest-to-pasture. The C content of the d-silt fraction decreased with time since conversion to pasture. Forest-derived C remained in all fractions with the highest concentration in the finest fractions, with the largest proportion of forest-derived soil C associated with clay minerals. Results from this work indicate that microaggregate formation is sensitive to changes in management and might serve as an indicator for management-induced soil carbon changes, and the soil C changes in the fractions are dependent on soil texture.

Objectifying early-number : a visual nomenclature to express mathematical domain knowledge

To address issues of divisive ideologies in the Mathematics Education community and to subsequently advance educational practice, an alternative theoretical framework and operational model is proposed which represents a consilience of constructivist learning theories whilst acknowledging the objective but improvable nature of domain knowledge. Based upon Popper’s three-world model of knowledge, the proposed theory supports the differentiation and explicit modelling of both shared domain knowledge and idiosyncratic personal understanding using a visual nomenclature. The visual nomenclature embodies Piaget’s notion of reflective abstraction and so may support an individual’s experience-based transformation of personal understanding with regards to shared domain knowledge. Using the operational model and visual nomenclature, seminal literature regarding early-number counting and addition was analysed and described. Exemplars of the resultant visual artefacts demonstrate the proposed theory’s viability as a tool with which to characterise the reflective abstraction-based organisation of a domain’s shared knowledge. Utilising such a description of knowledge, future research needs to consider the refinement of the operational model and visual nomenclature to include the analysis, description and scaffolded transformation of personal understanding. A detailed model of knowledge and understanding may then underpin the future development of educational software tools such as computer-mediated teaching and learning environments.
