Análise entoacional na Amazônia: um estudo comparativo interdialetal das variedades do português falado em Mocajuba e Cametá (PA)

Este trabalho compreende um estudo comparativo das descrições prosódicas prévias sobre as variedades de Mocajuba e Cametá (PA) no seio do projeto AMPER-POR (COSTA, em andamento). Visa-se à descrição do comportamento entoacional de sentenças nas modalidades declarativa neutra e interrogativa total. Os parâmetros acústicos de frequência fundamental (doravante F0), duração e intensidade foram foco de análise. Os procedimentos metodológicos adotados foram previamente estabelecidos pelo projeto AMPER-POR (CRUZ et al., 2012). Os movimentos melódicos das curvas de F0, nas modalidades frasais interrogativas e declarativas, para a variedade de Cametá, registraram menos variação intersilábica de F0, em relação a Mocajuba, indicando, portanto, essa variedade como tendo maior musicalidade, nos três tipos de acento lexical. Desta forma, apenas os resultados concernentes à variação melódica de F0 da variedade falada em Mocajuba assemelha-se com padrões entoacionais encontrados para outras regiões brasileiras, mais precisamente para o Norte e Nordeste brasileiro conforme descrito por Moraes (2003 apud SILVA e CUNHA, 2012, p. 10) e Silva e Cunha (2012). O parâmetro acústico de duração apresentou uma distinção dialetal significativa, posto que os dados de Cametá registraram sílabas mais longas, em relação a Mocajuba. A intensidade não apresentou variação significativa entre os dialetos estudados

CARACTERIZAÇÃO PROSÓDICA DO PORTUGUÊS FALADO NA AMAZÔNIA: VARIEDADE LINGUÍSTICA DE MOCAJUBA (PA)

O presente estudo compreende um aprofundamento de descrições prosódicas prévias sobre a variedade de Mocajuba no seio do projeto AMPER-POR (COSTA, 2015). Trata-se de uma abordagem acústica da variação prosódica dialetal, mais precisamente relacionada à entoação modal. Para a análise acústica, os valores de F0 em Hz foram estilizados pelo programa Prosogram (MERTENS, 2004) com valores de duração relativa das unidades V2V (BARBOSA, 2007) e, em seguida, a duração e a intensidade de cada locutor foram normalizadas em z-score (CAMPBELL, 1992). Os resultados evidenciaram que o fator sexo e escolaridade determinam diferenças prosódicas na variedade de Mocajuba, Pará

Measurement of the B0s→μ+μ− Branching Fraction and Effective Lifetime and Search for B0→μ+μ− Decays

A search for the rare decays Bs0→μ+μ- and B0→μ+μ- is performed at the LHCb experiment using data collected in pp collisions corresponding to a total integrated luminosity of 4.4  fb-1. An excess of Bs0→μ+μ- decays is observed with a significance of 7.8 standard deviations, representing the first observation of this decay in a single experiment. The branching fraction is measured to be B(Bs0→μ+μ-)=(3.0±0.6-0.2+0.3)×10-9, where the first uncertainty is statistical and the second systematic. The first measurement of the Bs0→μ+μ- effective lifetime, τ(Bs0→μ+μ-)=2.04±0.44±0.05  ps, is reported. No significant excess of B0→μ+μ- decays is found, and a 95% confidence level upper limit, B(B0→μ+μ-)<3.4×10-10, is determined. All results are in agreement with the standard model expectations.A search for the rare decays $B^0_s\to\mu^+\mu^-$ and $B^0\to\mu^+\mu^-$ is performed at the LHCb experiment using data collected in $pp$ collisions corresponding to a total integrated luminosity of 4.4 fb$^{-1}$. An excess of $B^0_s\to\mu^+\mu^-$ decays is observed with a significance of 7.8 standard deviations, representing the first observation of this decay in a single experiment.

Análise acústica da relação acento versus entoação no português falado em Mocajuba: contribuições para o Projeto Amper-Norte

A presente Dissertação faz parte do projeto Atlas Prosódico Multimédia da Região do Norte do Brasil (AMPER-NORTE) e que, por sua vez, está vinculado ao projeto Atlas Prosódico Multimedia do Português (AMPER-POR). Seu objetivo principal é contribuir com o projeto AMPER-NORTE, com a caracterização da variação prosódica dialetal do português falado na zona urbana do município de Mocajuba (PA). Os procedimentos metodológicos adotados foram previamente estabelecidos pelo projeto AMPER. O corpus foi constituído com uma amostra de fala de seis informantes, três do gênero masculino e três do gênero feminino; uma mulher (BF51) e um homem (BF52) do ensino Fundamental, uma mulher (BF53) e um homem (BF54) do ensino Médio, uma mulher (BF55) e um homem (BF56) do ensino Superior, da variedade do português falado em Mocajuba. O corpus do município é formado por 102 frases, do tipo SVC (sujeito + verbo + complemento), com complemento adjetival e indicadores de lugar. Cada sentença foi repetida seis vezes, totalizando 612 frases por informante. A análise foi feita a partir de dados relativos aos seis informantes, para tanto foram selecionadas 42 frases, sendo 21 afirmativas e 21 interrogativas totais com sintagmas nominais simples ou compostos, elas foram selecionadas de modo a contemplar as três pautas acentuais do português apresentando um total de 14 oxítonas, 14 paroxítonas e 14 proparoxítonas. A análise acústica das vogais foi feita em seis etapas e os resultados mostram que os parâmetros físicos acústicos de freqüência fundamental (F0) e duração (ms) demonstraram resultados relevantes para esta análise, confirmando os referidos parâmetros como complementares na distinção das modalidades frasais nesta variedade em estudo. A F0 torna-se relevante, pelo movimento em formato de pinça, que ocorre preferencialmente na sílaba tônica, do vocábulo-alvo, nominal, nas três pautas acentuais e a duração mostra que as pautas acentuais (oxítona, paroxítona e proparoxítona) registraram valores inversamente proporcionais, confirmando-se como um parâmetro distintivo. Na intensidade, não se observou distinção suficientemente satisfatória para confirmá-la como complementar à F0 e ms na variedade do português falado em Mocajuba.ABSTRACT: The present dissertation is part of AMPER-NORTE project (Atlas Prosódico Multimédia da Região do Norte do Brasil) and is linked to AMPER-POR project (Atlas Prosódico Multimedia do Português). Its main objective is to contribute to AMPER-NORTE project, featuring the dialectal prosodic variation of the Portuguese spoken in the urban area of Mocajuba (PA). The methodological procedures have been previously established by AMPER project.The corpus has been built with a speech sample of six informants, three males and three females: a woman (BF51) and a man (BF52) of elementary education, a woman (BF53) and a man (BF54) of middle education, a woman (BF55) and a man (BF56) of higher education, variety of Portuguese spoken in Mocajuba.Therefore, the corpus of the city of Mocajuba consists of 102 sentences of the type SVC (subject + verb + complement) with adjectival complement and indicators of place. Each sentence was repeated six times, totaling 612 sentences per informant. The analysis was made from data relative to the six informants. Therefore, 42 sentences were selected, 21 affirmative and 21 total interrogative with noun phrases simple or compound, they were selected to take account of the three accentual guidelines of Portuguese presenting a total of 14 oxytones, 14 paroxytones and 14 proparoxytone. The acoustic analysis of vowels was made in six stages and the results show that acoustic physical parameters of fundamental frequency (F0) and duration (ms) showed significant results for this analysis, confirming such parameters as complementary in the distinction of phrasal modalities in this range under study. The F0 becomes relevant, by moving on clamp format, which preferably occurs in the stressed syllable of the target word, nominal, in the three accentual guidelines and the duration shows that the accentual guidelines (oxytone, paroxytone and proparoxytone) recorded inversely proportional values and it is confirmed as a distinctive parameter. In the intensity, there was not enough satisfactory distinction to confirm it as complementary to F0 and ms in the variety of Portuguese spoken in Mocajuba

Effects of Four Days Hiking on Postural Control

<div><p>Hiking is a demanding form of exercise that may cause delayed responses of the postural muscles and a loss of somatosensory information, particularly when repeatedly performed for several days. These effects may negatively influence the postural control of hikers. Therefore, the aim of this study was to investigate the effects of a four-day hike on postural control. Twenty-six adults of both sexes travelled 262 kilometers, stopping for lunch and resting in the early evening each day. Force platforms were used to collect center of pressure (COP) data at 100 Hz for 70 seconds before hiking started and immediately after arriving at the rest station each day. The COP time course data were analyzed according to global stabilometric descriptors, spectral analysis and structural descriptors using sway density curve (SDC) and stabilometric diffusion analysis (SDA). Significant increases were found for global variables in both the anterior-posterior and medial-lateral directions (COP sway area, COP total sway path, COP mean velocity, COP root mean square value and COP range). In the spectral analysis, only the 80% power frequency (F80) in the anterior-posterior direction showed a significant increase, reflecting the increase of the sway frequencies. The SDC revealed a significant increase in the mean distance between peaks (MD) and a significant decrease in the mean peak amplitudes (MP), suggesting that a larger torque amplitude is required for stabilization and that the postural stability is reduced. The SDA revealed a decrease in the long-term slope (Hl) and increases in the short-term (Ks) and the long-term (Kl) intercepts. We considered the likelihood that the presence of local and general fatigue, pain and related neuromuscular adaptations and somatosensory deficits may have contributed to these postural responses. Together, these results demonstrated that four days of hiking increased sway frequencies and deteriorated postural control in the standing position.</p></div
