Línguas de ritmo silábico

One of the most controversial issues in the history of Phonetics is the discussion about the typology of speech rhythm. Out of the Greek and Latin tradition on poetry versification, the notion of rhythm has been misunderstood as speech rate. In the early years of the 20th century, a dichotomy merged classifying the speech rhythm into stress-timed and syllable-timed languages, inspired by the old theory of poetic versification. Following the same old pattern, later on, a third type of language were proposed: the moraic languages, initially attributed only to Japanese. With the facilities to carry on acoustic research, in the second half of the 20th century, the typology of language rhythm came to a dead end. Different types of language were set out. This paper discusses these ideas, showing a great misunderstanding among researchers in relation to the characterization of a syllable-timed language. The notion of mora is revisited and its role in the study of speech rhythm is better defined.

Differences in acoustic and perceptual parameters of the voice between elderly and young women at habitual and high intensity

The present study aimed to compare elderly and young female voices in habitual and high intensity. The effect of increased intensity on the acoustic and perceptual parameters was assessed. Sound pressure level, fundamental frequency, jitter, shimmer, and harmonic to noise ratio were obtained at habitual and high intensity voice in a group of 30 elderly women and 30 young women. Perceptual assessment was also performed. Both groups demonstrated an increase in sound pressure level and fundamental frequency from habitual voice to high intensity voice. No differences were found between groups in any acoustic variables on samples recorded with habitual intensity level. No significant differences between groups were found in habitual intensity level for pitch, hoarseness, roughness, and breathiness. Asthenia and instability obtained significant higher values in elderly than young participants, whereas, the elderly demonstrated lower values for perceived tension and loudness than young subjects. Acoustic and perceptual measures do not demonstrate evident differences between elderly and young speakers in habitual intensity level. The parameters analyzed may lack the sensitivity necessary to detect differences in subjects with normal voices. Phonation with high intensity highlights differences between groups, especially in perceptual parameters. Therefore, high intensity should be included to compare elderly and young voice.

Perfil clínico de crianças com indicação da cirurgia das tonsilas em um hospital terciário universitário

The indications for adenotonsillectomy in pediatric patients have changed considerably during the 90th decade. Local or systemic complications of the adenoid or tonsil hypertrophy itself have now been substituted by signs of obstructive ventilatory disturbances, including obstructive sleep apnea as the major indications for surgery. Objective: This study analyses the clinical profile of children submitted to adenotonsilectomy in their pre and postoperative state, at Botucatu Medical School-State University São Paulo, UNESP. Methods: 332 children of both genders, aged 1 to 12 years, who underwent adenotonsillectomy between 1999 and 2004, were studied, focused on epidemiological profile, pre and postoperative (1 month) symptoms, obtained from medical records. Height and weight were compared to brazilian normal age related values. Results: We found a predominance of the male gender, except in he group aged from 10 to 12 years. Considering wheight and height, we found important failure to thrive, mostly for height deficit. Among clinical aspects, we found a significant reduction in obstructive symptoms like snoring or apneia (p<0001) in the postoperative period. Conclusion: Our results were similar to the literature findings of patients clinical profile. The major indication for adenotonsillectomy in our service was clinical diagnosis of obstructive sleep apnea.

Leitura em uma criança surda após equivalência de estímulos

This study aimed to evaluate the effects of a systematic teaching of relation between printed words and Brazilian Sign Language on the emergence of reading in one child with deafness, user of Brazilian Sign Language, diagnosed with deafness bi-lateral deep user of hearing, with 9 years and 4 months of age, enrolled in 4th year elementary school. Baseline evaluation selected nine words and their signs and figures to compose the teaching steps and tests that consisted of: (a) relationship between a sign and figure teaching, (b) the relationship between sign and printed word, (c) test of relationship between figure and the printed word and its symmetric (d) test signal in front of picture and the printed word. The participant learned the relationship between sign, figure and printed word and demonstrated reading. This procedure was effective for the participant to emit signals, verbally agreed with the community of Libras in front of textual stimuli, which is characterized as reading.

Miedo e inseguridad de la gestante durante el trabajo de parto como motivos para la demanda de internación precoz

Objective. To identify reasons why women look for early health care attention at the end of pregnancy. Methodology. Qualitative study based in socio-existential phenomenology proposed by Alfred Schütz. Nine pregnant women who consulted to the maternity service without being in real labor were interviewed. Results. The following analysis categories emerged: Having different symptoms or signals from the ones they had felt or been informed about, not being able to identify real labor, fear to fetal complications for being close to the probable labor date, feeling calmer when being seen by professionals of the institution, lack of problem solving by other services of the health institution, fearing out of hospital delivery, imitating real labor, looking for tranquility in the idealization of labor and modifying behaviors to guarantee attention. Conclusion. Women are insecure and fear because of a fragmented health care, where they do not perceive themselves linked to the prenatal control program anymore, and at the same time they don’t find the health care assistance they want.

Estudios tafonómicos en foraminíferos bentónicos como proxy de hidrodinámica y sedimentología en el gradiente Río de La Plata – Océano Atlántico Sur Occidental

Los foraminíferos bentónicos representan un excelente proxy geológico, ya que sus caparazones son incorporados en el sedimento y pasan a comportarse como granos sedimentares durante los eventos de transporte y erosión, permitiendo así, el registro de condiciones y eventos que ocurren en los océanos. De este modo, son usados para describir patrones de hidrodinámica y evaluar índices de deposición, erosión y retrabajamiento del sedimento en los ambientes marinos. Concretamente, las regiones costeras representan zonas de alta complejidad ambiental, debido a que en ellas se da la mezcla de agua tanto de origen continental como marino, y a su vez, al efecto de la descarga fluvial que aporta material particulado del continente para el océano. El Río de la Plata (RdLP) representa el cuarto mayor estuario del mundo y el segundo del continente americano, lo cual convierte al sistema RdLP-Océano Atlántico en un complejo gradiente estuarino de interés en estudios sedimentológicos con posteriores aplicaciones paleo-climáticas y paleo-ecológicas del Cuaternario Superior. En el presente estudio, se registra a partir de las asociaciones muertas, para la región del estuario entrada de agua marina hasta la zona del frente termohalino. Dichas asociaciones se caracterizaron por especies típicas de plataforma y aguas frías. La región marina del RdlP registró los mayores porcentajes de abrasión y fragmentación de caparazones, indicando una zona de alta energía. Por otro lado, en la región más oceánica las asociaciones muertas reflejaron un transporte en dirección norte, influenciado por la pluma del RdlP. Cabe resaltar la presencia en esta región de una isla barrera, vestigio de una paleo-costa producto de una regresión Holocénica. Este local se caracterizó por un aumento de la abrasión y fragmentación mostrando la gran hidrodinámica presente. En todos los casos existió correlación entre las señales tafonómicas y los datos geo-químicos (sedimentología, pH, oxígeno disuelto, carbono orgánico y nitrógeno total)
