Padrões de dominância manual, podálica e performance motora em gêmeos

O método de gêmeos envolve a análise diferencial de gêmeos monozigóticos (MZs) e dizigóticos (DZs) a fim de determinar a proporção de variância em um determinado traço atribuível a fatores genéticos e ambientais. Sendo geneticamente idênticos, os gêmeos MZs tendem a apresentar alto índice de concordância em vários atributos comportamentais, enquanto que, os DZs, compartilham 50 % da carga genética, manifestando um reduzido grau de concordância. Todavia, pesquisadores têm investigado possíveis mecanismos genéticos subjacentes do desenvolvimento cerebral para dominância manual e, não têm encontrado utilidade no método de gêmeos, pois, desde 1924, em todos os estudos de dominância manual em gêmeos, a taxa de discordância para o canhotismo e destrimanismo têm sido similares em MZs e DZs. Além disso, frequentemente gêmeos mostram taxa mais alta de prevalência para o canhotismo que os não gêmeos. O objetivo deste estudo foi investigar as possíveis diferenças entre gêmeos destros e canhotos (MZs e DZs combinados) e não gêmeos em variáveis fenótipicas específicas relacionadas à dominância manual, incluindo dominância podálica (chute de penalty), consistência de dominância manual, canhotismo familiar (CF+), postura manual e medidas de habilidades motoras em três testes : Batidas digitais, Tabuleiro de Annett e Pontilhar Pontinhos. Foram avaliados 286 gêmeos ( 255 destros, 34 canhotos) e, 251 não gêmeos (141 destros e 110 canhotos). A análise dos dados revelou o aumento de canhotismo no sexo masculino em três vezes mais do que no feminino. Além disto, destros e canhotos gêmeos foram mais mistos em suas dominâncias manuais e apontaram alta incidência de CF+ entre parentes de primeiro grau que não gêmeos canhotos e destros. Em concordância com estudos anteriores, a frequência de chute contralateral foi mais alta nos mistos do que nos que apresentaram consistência na dominância manual, especialmente entre os canhotos. No que diz respeito à habilidade manual, não foram encontradas diferenças significativas nos três testes de habilidade manual. Conforme as expectativas, destros e canhotos foram mais proficientes na manipulação do estímulo com suas mãos dominantes. Em todas as três medidas, em contraste com os destros, os canhotos (gêmeos e não gêmeos) apresentaram redução entre as assimetrias manuais. Por extensão, o aumento da prevalência de canhotismo entre gêmeos não poderia ser atribuída a influências patológicas, inversão de assimetria ou ordem de nascimento. É possível, levar em consideração, observando a diferença robusta em dominância manual mista que, o padrão de lateralização neuromotora, pode ser mais difusamente organizado nos hemisférios dos gêmeos que em não gêmeos, mas, esta sugestão requer evidência direta, pelo menos a partir de testes de neuro-imagem.

Bem jurídico e princípio da proporcionalidade: uma análise crítica da pena em abstrato

A pesquisa constata a existência de dispositivos na legislação penal brasileira em que a pena em abstrato encontra-se desproporcional, seja pela ausência de um bem jurídico merecedor da tutela penal, seja porque o quantum da pena não condiz com os parâmetros da proporcionalidade. Para tanto, apresenta o bem jurídico penal, expondo sua síntese evolutiva, seu conceito, os princípios da intervenção mínima e da ofensividade, bem como as questões pertinentes a existência de bens jurídicos penais supra individuais e a problemática das imposições constitucionais de criminalização. Analisa o principio da proporcionalidade, desenvolvendo seu conceito, conteúdo, sua origem histórica e evolução, a consagração constitucional e a nomenclatura no direito comparado. Quanto ao conteúdo da proporcionalidade, adota a corrente que apresenta os subprincípios da idoneidade, necessidade e proporcionalidade em sentido estrito como elementos formadores da proporcionalidade em sentido amplo. Traz alguns exemplos de normas penais que fogem a regra da proporcionalidade, considerando o bem jurídico sob tutela. Conclui pela necessidade de se adequar a legislação penal brasileira aos parâmetros da proporcionalidade e as imposições da doutrina do bem jurídico penal, descriminalizando condutas ou adequando a pena em abstrato.

Orações concessivas independentes à luz da gramática discursivo-funcional

This paper investigates, in light of the theory of Functional Discourse Grammar (HENGEVELD; MACKENZIE, 2008), the concessive clause that is not subordinated to other clauses, i.e., it has no semantic or syntactic relations with clauses before or after it, and which we call Independent Concessive. The aim is to describe the discursive properties and the semantic, morphosyntactic and prosodic structure of this type of clause, showing that its relevance is in the construction and organization of discourse. The results indicate that the Independent Concessive works in speech as a parenthesis which interrupts the discursive course and is then highlighted by a special prosodic contour, combined with the presence of Interactive Acts. It is therefore a Move, the highest layer of the Interpersonal Level, the level that relates to the pragmatic aspects of the grammar of a language. The universe of research used is the Iboruna corpus, a database that records a variety of Portuguese from the Northwest of São Paulo.

Integração conceptual na descrição de fenômenos gramaticais do português

Functional grammar currently has a great acceptance in linguistics, mainly because it can enlighten grammatical facts' motivation in the structure of a text. From its emergence, the tradition of studying grammar by grammar has come to an end. Demonstrative pronouns, for instance, have begun to be viewed as efficient tools of text cohesion, used to resume terms from previous clauses. This task, however, ends up leaving an endless trail of black boxes. How is it possible to explain the origin of demonstratives' anaphoric functioning if they are originally used to indicate things or people relative to the interlocutors' spatial position? This work aims at showing that Cognitive Linguistics arises just as an option for opening those black boxes. This article focuses on one of its themes - the conceptual blending theory - to support this possibility. Firstly, it was necessary to integrate the cognitive model into the complexity theory, according to Bybee (2010) and Castilho (2009), who understand language as a complex adaptive system. After that, a brief updated description on the conceptual blending theory is made and its application in some grammatical facts of the Brazilian Portuguese language is suggested under the morphological and syntactic levels.

Reconfiguração de sistemas de distribuição utilizando metaheurísticas e critérios de confiabilidade

In an ever more competitive environment, power distribution companies must satisfy two conflicting objectives: minimizing investment costs and the satisfaction of reliability targets. The network reconfiguration of a distribution system is a technique that well adapts to this new deregulated environment for it allows improvement of reliability indices only opening and closing switches, without the onus involved in acquiring new equipment. Due to combinatorial explosion problem characteristic, in the solution are employed metaheuristics methods, which converge to optimal or quasi-optimal solutions, but with a high computational effort. As the main objective of this work is to find the best configuration(s) of the distribution system with the best levels of reliability, the objective function used in the metaheuristics is to minimize the LOLC - Loss Of Load Cost, which is associated with both, number and duration of electric power interruptions. Several metaheuristics techniques are tested, and the tabu search has proven to be most appropriate to solve the proposed problem. To characterize computationally the problem of the switches reconfiguring was developed a vector model (with integers) of the representation of the switches, where each normally open switch is associated with a group of normally closed switches. In this model simplifications have been introduced to reduce computational time and restrictions were made to exclude solutions that do not supply energy to any load point of the system. To check violation of the voltage and loading criteria a study of power flow for the ten best solutions is performed. Also for the ten best solutions a reliability evaluation using Monte Carlo sequential simulation is performed, where it is possible to obtain the probability distributions of the indices and thus calculate the risk of paying penalty due to not meeting the goals. Finally, the methodology is applied in a real Brazilian distribution network, and the results are discussed.

Análise da viabilidade econômica na implantação de inversores frequência em sistemas de bombeamento

The present work aims to conduct a study of the economic feasibility of the implementation of variable frequency inverters in pump systems with variable flow rates. The concern with the reduction of energy expenditure in industries raised in 2001 due to the energy crisis that hit Brazil at that time, forcing industries to reduce their electric costs under penalty of fines if this were not done (MOREIRA, 2008). Frequency inverter is an electronic device that allow greater control in the operation of pumping systems and also a reduction in electrical consumption, being a viable solution to achieve a reduction in energy consumption. For the development of this work, approaching important topics in pumping systems was necessary in order to make a correct choice of hydraulic pumping and also other components responsible for the operation of the system , such as electric motors and frequency inverters. In the case study, a theoretical analysis of the behavior of electrical consumption in systems with variable flow rates was performed, comparing when the system is operated via frequency inverters and when the system is operated without such a device. As expected, the result of the implantation of the device was quite satisfactory, and the primary goal of reducing energy expenditure was achieved. Also important to highlight the environmental issue of this work, as all forms of energy production affects nature in some way, achieving a reduction in consumption also contributes indirectly in environmental conservation

Da descrição ao ensino da oração adjetiva: a perspectiva dos livros didáticos de língua portuguesa

This paper aims at investigating the treatment given to relative clauses by elementary school text books, evidencing how the teaching of grammar is proposed in the teacher’s books. As a consequence, this study also intends to discuss important aspects to be considered as far as the teaching of relative clauses is concerned. In order to achieve that objective, five Portuguese text books (approved by the Programa Nacional do Livro Didático-2014) were selected so that the grammar teaching proposals could be analyzed in relation to the definition and to the distinguishing criteria between defining and non-defining relative clauses. Results show that the teaching of relative clauses (as proposed by the teacher’s books) still reflects the postulates of the traditional grammar, based on activities of identification and classification of morphosyntactic units, ignoring the pragmatic and prosodic aspects.

Interrogativas encaixadas vs. relativas sem antecedente: contribuições da Gramática Discursivo-Funcional

This work deals with the distinction between embedded questions and headless relatives, that was already pointed out as problematic in several studies based on generative approach. The purpose is to examine to what extent functional aspects, as proposed by the theory of Functional Discourse Grammar (HENGEVELD; MACKENZIE, 2008) to describe the two types of clauses can contribute to the explanation of the differences and similarities between them. Based on representative occurrences of spoken Brazilian Portuguese, we demonstrated that the approach of Functional Discourse Grammar provides important parameters for defining the nature of these two types of clauses, in both formal and functional (semantic-discursive) terms, contributing thus to the existing proposals for the distinction between these clauses.

Percurso diacrônico de completivas introduzidas por 'como' no português

As a more extensive issue, this paper deals with the polysemy attested in all Romance languages between interrogative pronouns and subordination markers in complex sentences. It investigates, specifically, the behavior of objective complement clauses introduced by “como” (“how”) in constructions in which they occur as equivalent to the meaning of prototypical declarative complement clause introduced by the conjunction “que” (“that”). It analyzes complement clauses introduced by “como” and “que” occurring in representative Portuguese texts from the thirteenth to the twentieth centuries. The results of the comparative analysis between the two forms of clausal complement show that in archaic Portuguese “como” was used primarily to introduce complement clauses of factive verbs. When the complement clause is introduced by “como”, the content that is presupposed as true due to the meaning of matrix verb has reinforced this factuality. In the passage from the archaic to the modern period, there was a drastic decrease in the frequency of occurrences of complement clauses with “como”, which are replaced by the form of completive introduced by the conjunction “que” in the context of factual constructions. In contemporary Portuguese, this replacement is fully established. Complement clauses with “como” remain rare and limited to specific contexts in which “como” maintains its reinforcement function of factual meaning.
