A escrita é uma ferramenta poderosa utilizada pelo homem desde que ele descobriu que poderia se comunicar sobre um suporte fixo e não somente pela fala. Ao longo dos anos, o homem desenvolveu essa ferramenta e o suporte onde ela era inserida, transformando e desenvolvendo ambos através de papiros, pergaminhos e códices, até chegar à imprensa, que revolucionou de vez a escrita com a introdução dos sinais de pontuação na mesma. Com o passar dos anos e com o advento da literatura moderna, o suporte textual foi cada vez sendo mais valorizado e trabalhado, até chegarmos a escritores modernos como Samuel Beckett. Mas por que ritmo e escrita? Porque ambos estão intimamente relacionados: não existe escrita sem ritmo. De fato, não há discurso sem ritmo, pois ele é organizado pelo ritmo. Assim, a sintaxe e a pontuação fazem parte do jogo rítmico textual. Pode-se dizer que ritmo, sintaxe e pontuação formam uma tríade poderosa e analisar esses elementos nos três últimos romances de Samuel Beckett é um trabalho importante para se mostrar um trabalho inovador com o ritmo e a escrita.; Writing is a powerful tool used by man since he discovered he could communicate on a fixed support, not only through speech. Over the years...

Queixas de insônia e sonolência excessiva são comuns na investigação dos distúrbios respiratórios do sono; os transtornos do sono relacionados ao ritmo circadiano talvez sejam as causas mais freqüentemente esquecidas no diagnóstico diferencial destes sintomas. Estes transtornos se manifestam por desalinhamento entre o período do sono e o ambiente físico e social de 24 h. Os dois transtornos do sono relacionados ao ritmo circadiano mais prevalentes são o de fase atrasada (comum em adolescentes) e avançada do sono (comum em idosos), situações nas quais o período de sono se desloca para mais tarde e mais cedo, respectivamente. As possíveis confusões com insônia e sonolência excessiva tornam importante ter sempre em mente estes transtornos. Entretanto, há nove possíveis diagnósticos, e todos são de interesse clínico. Como a luz é o principal sinal para sincronizar os relógios biológicos, pessoas cegas e trabalhadores em turnos e noturno são os mais propensos a desenvolver transtornos do sono relacionados ao ritmo circadiano. Neste artigo, revisa-se a nova classificação internacional dos transtornos do sono relacionados ao ritmo circadiano.; Insomnia and excessive sleepiness are common in the investigation of sleep-disordered breathing. Circadian rhythm sleep disorders are perhaps the most often overlooked conditions in the differential diagnosis of these symptoms. Circadian rhythm sleep disorders manifest as misalignment between the sleep period and the physical/social 24-h environmental cycle. The two most prevalent circadian rhythm sleep disorders are delayed sleep phase (common in adolescents) and advanced sleep phase (common in the elderly)...

Introdução: O ritmo social é um conceito que integra a relação entre Zeitgebers (sincronizadores) sociais e os marcadores de tempo endógenos, e pode ser avaliado com a Escala de Ritmo Social (Social Rhythm Metric-17, SRM-17). O objetivo deste estudo foi realizar a adaptação da versão brasileira da SRM-17 para o português angolano, comparando as duas escalas em populações que utilizam o mesmo idioma mas apresentam diferenças culturais. Métodos: A versão brasileira da SRM-17 foi submetida à avaliação de 10 estudantes universitários angolanos, que analisaram o grau de clareza de cada um dos 15 itens do instrumento usando uma escala visual analógica de 10 cm e propuseram modifi cações ao texto. Foi realizada revisão dos resultados para a elaboração da versão fi nal, bem como prova de leitura e relatório fi nal. Resultados: A versão fi nal angolana manteve uma equivalência de itens com relação à versão em português brasileiro. A versão avaliada demonstrou um grau satisfatório de clareza e equivalência semântica na maioria dos itens. Porém, alguns itens apresentaram um escore na clareza inferior à média aritmética de compreensão global do instrumento (8,38±1,0). Conclusão: Apesar de o português ser o idioma ofi cial nos dois países...

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and Economics; Speed and rhythm in organizations can be examined from different perspectives and disciplines. The purpose of this work project is to investigate a theme that has been gaining relevance over the last few decades in Organizational Sciences: how people cope with speed and rhythm at work. Twenty-four employees, from two generations, of various hierarchical levels from a wide range of organizations were interviewed. Net Generation and Baby Boom Generation, the two generations in question, were analysed in equal proportions to find reliable differences in their perceptions. Significant findings were attained after analysing the results: a) Different generations have similar perceptions about speed and rhythm at work; b) Technology encourages networks producing a lack of boundaries and it challenges traditional ways of work management. At first, this difference appears to be a generational perception but it is not; c) Net Generation is used to perform multitasking, as a method to deal with high speed and rhythm, while Boom Generation, in general, do not feel capable of doing it; d) Although most people agree with the Slow Movements philosophy...

Circadian rhythms are entrained to cyclic environmental cues such as the light-dark cycle and food availability. The suprachiasmatic nucleus of the hypothalamus is the main circadian oscillator in mammals and is entrained primarily by the light-dark cycle, although in some experimental situations food availability can affect its oscillation. Here we tested whether scheduled restricted feeding is capable of influencing the reentrainment of the motor activity rhythm (i.e., a behavioral rhythm controlled by the suprachiasmatic nucleus) to a 6-h phase advance of the light-dark cycle. Rats were housed in a standard 12 h:12 h light-dark cycle for 18 days, and then the time of lights-off was advanced. Rats subjected to scheduled restricted feeding starting on the first day of the light-dark shift showed faster reentrainment of the motor activity rhythm compared with control rats maintained with ad libitum food. The results showed that scheduled feeding effectively accelerates reentrainment of a behavioral circadian rhythm and suggest that the procedure may affect activity in the suprachiasmatic nucleus during the stage of reentrainment to light-dark shifts.

The expanding science of circadian rhythm biology and a growing literature in human clinical research on circadian rhythm sleep disorders (CRSDs) prompted the American Academy of Sleep Medicine (AASM) to convene a task force of experts to write a review of this important topic. Due to the extensive nature of the disorders covered, the review was written in two sections. The first review paper, in addition to providing a general introduction to circadian biology, addresses “exogenous” circadian rhythm sleep disorders, including shift work disorder (SWD) and jet lag disorder (JLD). The second review paper addresses the “endogenous” circadian rhythm sleep disorders, including advanced sleep phase disorder (ASPD), delayed sleep phase disorder (DSPD), irregular sleep-wake rhythm (ISWR), and the non–24-hour sleep-wake syndrome (nonentrained type) or free-running disorder (FRD). These practice parameters were developed by the Standards of Practice Committee and reviewed and approved by the Board of Directors of the AASM to present recommendations for the assessment and treatment of CRSDs based on the two accompanying comprehensive reviews. The main diagnostic tools considered include sleep logs, actigraphy, the Morningness-Eveningness Questionnaire (MEQ)...

For thousands of years, human beings have engaged in rhythmic activities such as drumming, dancing, and singing. Rhythm can be a powerful medium to stimulate communication and social interactions, due to the strong sensorimotor coupling. For example, the mere presence of an underlying beat or pulse can result in spontaneous motor responses such as hand clapping, foot stepping, and rhythmic vocalizations. Examining the relationship between rhythm and speech is fundamental not only to our understanding of the origins of human communication but also in the treatment of neurological disorders. In this paper, we explore whether rhythm has therapeutic potential for promoting recovery from speech and language dysfunctions. Although clinical studies are limited to date, existing experimental evidence demonstrates rich rhythmic organization in both music and language, as well as overlapping brain networks that are crucial in the design of rehabilitation approaches. Here, we propose the “SEP” hypothesis, which postulates that (1) “sound envelope processing” and (2) “synchronization and entrainment to pulse” may help stimulate brain networks that underlie human communication. Ultimately, we hope that the SEP hypothesis will provide a useful framework for facilitating rhythm-based research in various patient populations.

The circadian rhythm of black pigment migration of melanophores of the crab Chasmagnathus granulata and the variation in responsiveness of these cells to pigment-dispersing hormone (h-PDH), crustacean cardioactive peptide (CCAP), and red pigmentconcentrating hormone (RPCH) were investigated. Melanophores of C. granulata possess an endogenous circadian rhythm of pigment migration, with black pigments staying more dispersed during the day period and more aggregated during the night period. This rhythm seems to be largely dependent on an endogenous release of neurohormones from eyestalks, and to a lesser extent on a primary response to illumination. h-PDH was the most potent PDH isoform to induce pigment dispersion in both in vivo (EC50 = 0.4 pmol/animal) and in vitro (EC50 = 0.18 AM) assays. CCAP also induced pigment dispersion in vivo and in vitro assays (EC50=12 AM), but it was less potent than h- PDH. In vivo, RPCH induced a low and nondose dependent pigment aggregation, while in vitro, it had no effect on pigment migration. The responsiveness of melanophores of C. granulata to h-PDH was significantly higher during the day period when compared to the night period in both assays, in vitro and in vivo. These results suggest that the endogenous circadian rhythm of black pigment migration is dependent on both endogenous circadian rhythm of h-PDH synthesis and/or release from eyestalks and on an endogenous rhythm of responsiveness of melanophores to h-PDH.

Glossary of terms and notations ; Appendix B. Complete transcriptions and analysis.; Phrase rhythm is the interaction of grouping structure and metrical structure. In jazz improvisation, these structures behave in ways that theories of phrase rhythm designed for classical music cannot accommodate. Specifically, jazz improvisation involves the superimposition of a highly flexible grouping structure on a pre-determined and predictable metrical-harmonic scheme. In this context, theories of phrase rhythm that depend on voiceleading or harmony neglect the subtleties of grouping structure.
In this dissertation, I present a new method for the analysis of jazz phrase rhythm. I classify each phrase based on its relationship to the metrical hierarchy, as manifested in two characteristics: 1) the pattern of metrical accents it overlaps (prosody)...

Stroke is a neurological disorder caused by restriction of blood flow to the brain, which generates directly a deficit of functionality that affects the quality of life of patients. The aim of this study was to establish a short version of the Social Rhythm Scale (SRM), to assess the social rhythm of stroke patients. The sample consisted of 84 patients, of both sexes, with injury time exceeding 6 months. For seven days, patients recorded the time held 17 activities of SRM. Data analysis was performed using a principal components factor analysis with varimax rotation of the full version of SRM in order to determine which activities could compose brief versions of SRM. We then carried out a comparison of hits, the ALI (Level Activity Index) and SRM, between versions, by Kruskal-Walls and the Mann-Whitney test. The Spearman correlation test was used to evaluate the correlation between the score of the full version of SRM with short versions. It was found that the activities of SRM were distributed in three versions: the first and second with 6 activities and third with 3 activities. Regarding hits, it was found that they ranged from 4.9 to 5.8 on the first version; 2.3 to 3.8 in version 2 and 2.8 to 6.2 in version 3, the first the only version that did not show low values. The analysis of ALI...

This dissertation, which is based on the analysis of non-conventional segmentation data produzed by Brazilian and Portuguese children, shows the importance of initial writing data in order to discuss the linguistic rhythms of Brazilian Portuguese (BP) and European Portuguese (EP). The data were collected in texts which had been spontaneously written by Brazilian and Portuguese children who were attending the first grades in Elementary School (Pelotas, RS, Brazil) and the Basic School (Porto, Portugal). All texts belong to the a database named Banco de Textos de Aquisi????o da Escrita, at the Universidade Federal de Pelotas (FaE UFPel). Studies of rhythm in Phonology have been rather polemical and controversial, mainly the ones that discuss the rhythmic classification of languages. Abaurre and Galves (1998), based on an optimalist and minimalist approach, have developed a study of the rhythmic differences between BP and EP. The authors believe that the rhythm of every language is the result of the hierarchization of three principles: the integrity of the phonological word , the trochaic foot , and the foot binarity . After the detailed data description and analysis which link the prosodic constituents, the phonological processes and the stress...

This study determined whether a blood plasma melatonin rhythm persists in constant photothermal environments in the sleepy lizard, Tiliqua rugosa. It builds upon an earlier investigation which provided equivocal results as to whether an in vivo melatonin rhythm persists in constant dark (DD) and light (LL) and temperature in this species. Using more frequent sampling points and new assay techniques, the present study showed that the melatonin rhythm persisted for at least 6 days at temperatures of 25 and 33°C in constant dark (DD). The melatonin rhythm, however, was largely eliminated in constant light (LL) at 33°C, thereby contradicting some previous findings in other species of reptiles where melatonin levels were apparently insensitive to an unexpected pulse of light at night. These results demonstrate that the sleepy lizard has a persistent, possibly circadian rhythm of melatonin in DD and constant temperature, and that the rhythm is inhibited by LL and constant temperature. Therefore, the sleepy lizard pineal gland may be an independent oscillator capable of driving the melatonin rhythm and be a transducer of the seasonally changing external photothermal environment.; Bruce T. Firth, Ingrid Belan and David J. Kennaway; The definitive version is available at www.blackwell-synergy.com

Hintergrund: Die substratorientierte Ablation ventrikulärer Tachykardien (VT) bei Patienten nach Myokardinfarkt kann durch endokardiale Elektrogrammcharakteristika im Sinusrhythmus geleitet werden. Die Bedeutung von fraktionierten Elektrogrammen für eine Identifizierung von Arealen mit Ursprung klinischer VTs bei nicht-ischämischen Kardiomyopathie (NICM) wurde in der vorliegenden Studie untersucht. Methoden: 11 Patienten (8 männlich, 3 weiblich, mittlere LVEF 31 ± 11 %) wurden im Zeitraum vom Februar 2005 bis März 2008 einer elektrophysiologischen Untersuchung (EPU) unterzogen. Es wurde eine substratorientierte Ablation durchgeführt mit dem Ziel lokal verzögerte, fraktionierte Potentiale mit einer bipolaren Spannungamplitude von < 1,5 mV in bis zu 1 cm Umkreis um die beste VT-Pace-Map-Position zu abladieren. Der linke Ventrikel wurde in 17 Segmente eingeteilt und Segmente im Bereich des besten VT-Pace-Maps als arrhythmogenes Areal definiert. Als Kontrollareale wurden Areale mit räumlichem Abstand zum arrhythmogenem Areal definiert. Die bei der elektrophysiologischen Untersuchung des linken Ventrikels im Sinusrhythmus und/ oder während ventrikulärem Pacing aquirierten Elektrogramme wurden durch die Parameter bipolare Amplitude...

The daily rhythm of behavioral thermoregulation in sleepy lizards (Tiliqua rugosa) was studied in laboratory thermal gradients under a 12L∶12D photoperiod in autumn and spring. In both seasons, lizards showed distinctive daily rhythms of behavioral thermoregulation, selecting their highest body temperatures during the late photophase and lowest ones during the late scotophase or early photophase. When lizards were subjected to a period of constant darkness at both seasons, this rhythm persisted and free-ran with a period of 24.7 h, indicating that it is an endogenous circadian rhythm. Furthermore, the expression of this circadian rhythm varies seasonally in the amplitude of its free-running rhythm and in the phase at which the minimum Tb is selected during 12L∶12D. The seasonal variation in the expression of the circadian rhythm of behavioural thermoregulation in Tiliqua rugosa lizards is likely to reflect seasonal changes in the neural regulation of this rhythm.; David J.

Prosodic rhythm was measured for a sample of 20 African American and 20 European American speakers from North Carolina using the metric devised by Low, Grabe, and Nolan (2000), which involves comparisons of the durations of vowels in adjacent syllables. In order to gain historical perspective, the same technique was applied to the ex-slave recordings described in Bailey, Maynor, and Cukor-Avila (1991) and to recordings of five Southern European Americans born before the Civil War. In addition, Jamaicans, Hispanics of Mexican origin who spoke English as their L2, and Hispanics speaking Spanish served as control groups. Results showed that the North Carolina African American and European American groups were both quite stress-timed overall, with no significant difference between them. Spanish emerged as solidly syllable-timed, while Jamaican English and Hispanic English were intermediate. The ex-slaves were significantly less stress-timed than either younger African Americans or European Americans born before the Civil War. This finding suggests that AAE was once similar to Jamaican English in prosodic rhythm.

"In(ve)stigando o Ritmo: a Importância da Conscientização Rítmica Através da Percussão e sua Transposição para a Cena" é um trabalho que procura salientar a importância do estudo do ritmo como 'ferramenta' útil de pesquisa do intérprete em sua relação com a cena, desfrutando da linguagem percussiva como elo de ligação com a linguagem corporal. Fazendo uso dos conceitos rítmicos ligados à percussão e do movimento do corpo regrado pelo ritmo, buscamos estabelecer uma analogia que permita a aproximação destas duas abordagens, na tentativa de contribuir para o apuro - instigado pelo ritmo e investigado pelo corpo - da conscientização temporal da ação cênica, desde a ótica de quem toca o instrumento até a de quem é estimulado(a) por ele. Como demonstração prática de nossas reflexões serão apresentados trechos do espetáculo PRIMUS, material empírico do qual extraímos alguns de nossos pressupostos e no qual aplicamos alguns fundamentos advindos do estudo da percussão em sua relação criativa com a cena.

OBJECTIVE: To analyze the psychometric properties of Brazilian version of Social Rhythm Metric-17 and to present the score algorithm in regular shift employees. METHOD: This is a cross-sectional study. The Social Rhythm Metric assess the regularity of daily life associated to changes in biological rhythms. The scale was applied, during nine days, to 145 employees, 27.6 % male and 72.4% female, ages between 18 and 60, mean = 36.1 (sd = 9.87). Mean values were compared using the Student's t-test for independent samples and ANOVA. Factor analysis was performed using principal component analysis; the reliability analysis, through Spearman's correlation. RESULTS: The Student t test didn't reveal any significant difference between sex in IRA (t = 0.60; p = 0.55) or ETA (t = 0.67; p = 0.95). The factor analysis showed three components, the first was associated to survival related activities; the second, related to pleasure and work and the third was related to no essential survive activities. DISCUSSION: This version of the Social Rhythm Metric-17 instrument allows to assess an important human zeitgeber, contributing for other studies which can to evaluate the determinant role of social rhythm. CONCLUSION: The Brazilian version of social rhythm metric 17 presents validity of content and good test-retest reliability.

Experimental phonetic research on speech rhythm seems to have reached an impasse. Recently, this research field has tended to investigate produced (rather than perceived) rhythm, focussing on timing, i.e. duration as an acoustic cue, and has not considered that rhythm perception might be influenced by native language. Yet evidence from other areas of phonetics, and other disciplines, suggests that an investigation of rhythm is needed which (i) focuses on listeners? perception, (ii) acknowledges the role of several acoustic cues, and (iii) explores whether the relative significance of these cues differs between languages. This thesis, the originality of which derives from its adoption of these three perspectives combined, indicates new directions for progress. A series of perceptual experiments investigated the interaction of duration and f0 as perceptual cues to prosody in languages with different prosodic structures ? Swiss German, Swiss French, and French (i.e. from France). The first experiment demonstrated that a dynamic f0 increases perceived syllable duration in contextually isolated pairs of monosyllables, for all three language groups. The second experiment found that dynamic f0 and increased duration interact as cues to rhythmic groups in series of monosyllabic digits and letters; the two cues were significantly more effective than one when heard simultaneously...

Burton, Susan L.; The purpose of this study was to examine the effect of an audiation-based curriculum on rhythmic music aptitude and rhythm achievement of elementary school students. Specific research questions addressed in this study were (a) Is there a relationship between developmental rhythm music aptitude and rhythm achievement of first, second, and third grade students? (b) Does the relationship between rhythm music aptitude and rhythm achievement change with age? and, (c) Does age have an effect on rhythm achievement? Participants in this study (N = 183) were in grades one through three, from 10 intact homerooms. Students attended a general music class once a week for 45 minutes. The study lasted for five months. All participants engaged in 5 to 10 minutes of formal rhythm pattern instruction, which alternated between duple and triple meter patterns, each week. Improvisation activities were included in the lessons. At the end of the study, all participants took an oral improvisation test in duple and triple meters. Two independent judges scored each improvisation using a 5-point continuous rating scale. All participants also took a paper and pencil meter-labeling test. Gordon’s Primary Measures of Music Audiation (PMMA) (PMMA...
