Vozes periféricas: expansão, imersão e diálogo na obra dos Racionais MC's

This paper presents a reflection on the work of the rap group from São Paulo Racionais MC's, highlighting points of dialogue between his last two studio albums: Sobrevivendo no inferno, 1997, and Nada como um dia após o outro, 2002. We found, in this discursive course, the presence of voices which intertwine and indicate a collectivized speech, seeking the identification between the slums and the group's rhetoric, but they also point out to an immersion into the subjectivity, to the problematization of the discourse itself, acting as a form of debugging of the social experience in the favela. We argue further that Sobrevivendo no inferno represents a turning point in the thinking of the quartet. Thus, themes and perspectives present, although embryonically, in the first focused album, point to dramas that take shape in the second one.

Effect of different exercise programs on the psychological and cognitive functions of people with Parkinson's disease

The purpose of this study was to analyze the effect of different exercise programs on the psychological and cognitive functions in patients with Parkinson's disease (PD). Forty-five patients with PD participated in the study. The participants were randomized in three intervention programs: Group-1 (n=15, cognitive-activities), Group-2 (n=15, multimodal exercise) and Group-3 (n=15, exercises for posture and gait). The clinical, psychological and cognitive functions were assessed before and after 4 months of intervention. Univariate analysis did not reveal significant interactions between groups and time (p>0.05). However, univariate analysis for time revealed differences in stress level and memory. Participants showed less physical stress (p<0.01) and overall stress (p < 0.04) and higher performance in episodic declarative memory (p < 0.001) after exercise. These findings suggest that group work with motor or non-motor activities can improve cognitive and psychological functions of patients with PD.

Desenvolvimento de um computador de bordo para veículo Baja-SAE

The objective of this paper is show the development of an Eletronic Control Unit (ECU) for Baja-SAE vehicles from its requirements to final implementation. An ECU for Baja-SAE vehicles is made of electric and electronic circuits (appropriated to the hostile situations of an off-road competition) able to make important measurements for the running or stand-by vehicle performance. For this development, some concepts were studied: embedded electronics concepts (mainly microcontrollers and data acquisition circuits) and sensoring. Both the studies were made considering the off-road environment. After these initial studies, the elaboration of the basics hardware and software (under simulations) has begun, and this elaboration objectives maximum performance and low implementation cost. After the theorical studies, basic definition of the hardware and software’s architectures and simulations, the printed circuit boards (PCB) were made, as exhaustive tests in these boards for debugging and verify if the boards work well. Once the system was tested in the university, it ran into a regional Southeast competition in 2010, that definitely proved the efficiency of the whole system

Análise entoacional acústica e auditiva de alguns enunciados do português brasileiro

The main goal of this work is the analysis of theoretical and methodological aspects of speech melody variation (intonation), with special reference to the pronunciation of one speaker. In order to carry on this study, different types of sentences (declarative, questions, etc.) and the intonational focus as well as the speaker‟s attitude (irony, emphasis, etc.) were observed and analyzed with special acoustic software (PRAAT) and with an auditory analysis of a text read by the subject. The aim of this work is to verify whether the acoustic analysis matches with the auditory perception phonetically, according to M.A.K. Halliday‟s methodology, following Cagliari (2007), who adapted Halliday‟s model to describe the intonation of Portuguese

Estudo acústico da variação da frase interrogativa, com destaque para o dialeto paulista

With the new computational technology, the studies of acoustic phonetics started to have a special place. This brought a new way of seeing the phenomenon and to deal with it in the phonetics and in the phonology. Such studies have been developing even more, recently, with a facilitated use of computational programs specially developed to the acoustic analysis of speech, such as PRAAT. Programs like this have been very interesting and useful recently. The acoustic models of analysis have influenced the way the researchers came to see and to interpret the prosodic phenomenon. The current project investigates the acoustic production of declarative and interrogative sentences from the “paulista” Portuguese. This study contributes for a more detailed description of the phenomenon, also becoming inserted in the chart of “intonational” descriptions of the Brazilian Portuguese. The subject of this current project is the acoustic study of some intonation aspects from the speaking Portuguese in Brazil, with a special place to the “paulista” dialect. The current project´s purpose is to make a specific study of interrogatives sentences through the acoustic data analysis of “paulista” dialect speakers

Efeitos de relevância versus repetição de estímulo lingüístico na indução da memória declarativa

In the LTP (Long-Term Potentiation) model of learning and memory formation, elaborated in the context of molecular neurobiology, the opening of NMDA (N-Metyl-D-Aspartate) channels to entry of calcium ions into the post-synaptic neuron depends on two excitatory events: the repeated activation of the post-synaptic neuron by only one pre-synaptic neuron (Alternative 1), or its concomitant activation by two or more pre-synaptic neurons (Alternative 2). With the purpose of testing these alternatives, in the context of Cognitive Psychology, we presented to 73 university students a sequence of slides, with the duration of 6 seconds each, containing sentences (one for each slide) considered as being relevant or irrelevant for the subjects. Relevant sentences (R1) were presented only one time, while irrelevant ones were divided in three groups: the first one with sentences presented only one time (I1), the second with sentences presented three times (I3) and the third with sentences presented five times (I5). We conjectured that relevant sentences presented only one time would mobilize two or more brain excitatory pathways (corresponding to Alternative 2 above), while repeated irrelevant sentences would progressively activate the same sensory pathway. After the presentation of the sentences, the subjects answered a written questionnaire with questions about each presented sentence. The results indicate a prevalence of correct answers to R1 over I1, I3 and I5, suggesting that the relevance factor has greater weight than repetition in the induction of declarative memories

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.

Ordenação de constituintes em sentenças declarativas do português brasileiro

Based on Hengeveld and Mackenzie (2008)’s Functional Discourse Grammar (FDG), this article aims to analyze the natural and marked orderings of argument constituents in declarative sentences of Brazilian Portuguese taken in IBORUNA corpora. In this way, we conclude that the two natural orderings, proposed by Pezatti (1992), are determined by semantic factor, especially by semantic functions, while the marked ordering ir determined by pragmatic factor, especially by the attribution of pragmatic functions.
