    OBJETIVO: definir medidas aerodinâmicas em falantes do português brasileiro, sem queixas vocais, obtidas pelo programa EVA. MÉTODO: participaram do estudo 20 homens e 20 mulheres, que tiveram suas vozes analisadas. RESULTADOS: os valores médios referentes à pressão subglótica para vozes femininas e masculinas foram, respectivamente: Pressão subglótica= 5,84 hPa e 6,7 hPa, média da intensidade= 79,21 dB e 81,7 dB, média do fluxo oral= 0,09 dm³/s e 0,16 dm³/s, eficiência glótica= 13,87 dB/hPa e 12,78 dB/hPa, eficiência laríngea= 188,08 dB/(hPa.dm³/s) e 97,11 dB/(hPa.dm³/s), resistência laríngea= 96,26 hPa/(dm³/s) e 52,64 hPa/(dm³/s), média da frequência fundamental (F0)= 208,28 Hz e 136,56 Hz e pico da pressão do fluxo oral= 0,093 e 0,098. Houve diferença estatisticamente significante em relação ao gênero para as medidas de média de intensidade, eficiência laríngea, resistência laríngea e média da frequência fundamental. Os valores médios referentes ao fluxo oral para vozes femininas e masculinas foram respectivamente: Pressão subglótica= 6,05 hPa e 6,6 hPa, média da intensidade= 65,50 dB e 66,3 dB, média do fluxo oral= 0,10 dm³/s e 0,13 dm³/s, eficiência glótica= 11,12 dB/hPa e 11,77 dB/hPa, eficiência laríngea= 144,83 dB/(hPa.dm³/s) e 97,89 dB/(hPa.dm³/s), resistência laríngea= 78,98 hPa/(dm³/s) e 61,81 hPa/(dm³/s), média da F0= 222,52 Hz e 139,20 Hz e pico da pressão do fluxo oral= 0,047 e 0,053. CONCLUSÃO: o EVA é um programa ainda novo no Brasil, e a análise de medidas aerodinâmicas, em falantes do português brasileiro, permite a obtenção de valores de referência, possibilitando assim comparações com estudos futuros.<br>PURPOSE: to define aerodynamic measures in Brazilian Portuguese speakers without voice complaints, obtained by the EVA program. METHOD: the study included 20 men and 20 women who had their voices analyzed. RESULTS: the mean values with subglottic pressure for female and male voices were: Subglottic pressure = 5.84 hPa and 6.7 hPa; average intensity = 79.21dB and 81.7dB; oral mean flow = 0.09 dm3/s and 0.16 dm3/s; glottic efficiency = 13.87dB/hPa and 12.78 dB/hPa; laryngeal efficiency = 188.08 dB/(hPa.dm3/s) and 97.11dB/(hPa.dm3/s); laryngeal resistance = 96.26 hPa/(dm3/s) and 52.64 hPa/(dm3/s); mean fundamental frequency (F0) = 208.28 Hz and 136.56 Hz and peak mouth pressure flow = 0.093 and 0.098. There was a statistically significant difference in relation to gender for the measures of average intensity, efficiency, larynx, laryngeal resistance and mean fundamental frequency. The average flow for the oral female and male voices were: subglottic pressure = 6.05 hPa and 6.6 hPa; average intensity = 65.50 dB and 66.3 dB; oral mean flow = 0, 10 dm3/s and 0.13 dm3/s; glottic efficiency = 11.12 dB/hPa and 11.77 dB/hPa; laryngeal efficiency = 144.83 dB/( hPa.dm3/s) and 97.89 dB/( hPa.dm3/s); laryngeal resistance = 78.98 hPa/(dm3/s) and 61.81 hPa/( dm3/s); average F0 = 222.52 Hz and 139.20 Hz and peak pressure oral flow = 0.047 and 0.053. CONCLUSION: EVA is a new program in Brazil, and analysing the aerodynamic measures in Brazilian Portuguese speakers, allows us to obtain reference values, thus allowing comparisons with future studies

    OBJETIVO: Verificar se a área dos orifícios velofaríngeos obtida após o retalho faríngeo (RF) durante a respiração de repouso (AVFr) é um indicador do grau de fechamento velofaríngeo durante a fala (AVFf). MÉTODOS: Os sujeitos foram 62 pacientes com fissura de palato, associada ou não à fissura de lábio, de ambos os gêneros, com idades entre seis e 32 anos, submetidos ao RF há, pelo menos, 12 meses. AVFr e AVFf foram determinadas por meio da técnica fluxo-pressão. Valores de AVFr inferiores a 0,500 cm² foram considerados subnormais. A AVFf foi classificada como adequada (0-0,049 cm²), marginal (0,050-0,199 cm²) ou inadequada (>0,200 cm²). A associação entre os valores de AVFr e AVFf pós-cirúrgicos foi analisada por meio de um modelo de regressão logística. RESULTADOS: Após o RF, 92% dos pacientes com valores de AVFr subnormais (<0,500 cm²) apresentaram fechamento velofaríngeo adequado. A proporção de pacientes com valores de AVFr normais (>0,500 cm²) e fechamento velofaríngeo adequado foi menor, porém ainda expressiva (55%). Não houve associação estatisticamente significante entre as duas variáveis. CONCLUSÃO: A maioria dos pacientes com retalho largo apresentou fechamento velofaríngeo adequado durante a fala. Entretanto, os resultados mostraram que as dimensões dos orifícios velofaríngeos durante a respiração de repouso não podem predizer a eficácia do retalho faríngeo para a fala.<br>PURPOSE: To investigate whether postoperative velopharyngeal orifice area during nasal breathing at rest (VPAb) can predict velopharyngeal closure during speech (VPAs). METHODS: The subjects were 62 patients with cleft palate, associated or not with cleft lip, of both genders, with ages between six and 32 years, who underwent pharyngeal flap surgery (PFS) at least 12 months before the evaluation performed for this study. VPAb and VPAs were assessed using the pressure-flow technique. VPAb values below 0.500cm² were considered subnormal. VPAs was categorized as adequate (0-0.049cm²), borderline (0.050-0.199cm²) or inadequate (>0.200cm²). A logistic regression model analyzed the association between VPAb and VPAs. RESULTS: After PFS, 92% of the patients with subnormal VPAb values (<0.500cm²) presented adequate velopharyngeal closure. The percentage of patients with normal VPAb values (>0.500cm²) who also presented adequate closure was smaller, but still significant (55%). The association between VPAb and VPAs values was not statistically significant. CONCLUSION: Most patients with large flaps presented adequate velopharyngeal closure during speech. However, the findings show that the velopharyngeal orifice area during breathing is not a good predictor of the effectiveness of the pharyngeal flap for speech

    Non-Economic Factors in Economic Geography and in 'New Regionalism': A Sympathetic Critique

    No full text
    In the current debate on local and regional development and after several 'turns', dominant critical models have found some security in institutional, cultural and evolutionary approaches. Interest today centres on success and competitiveness and how they are reproduced in a few paradigmatic regions. A distinctive feature of these regions and places is "the embeddedness of certain non-economic factors "such as" social capital, trust and reciprocity "based on familiarity, face-to-face exchange, cooperation, embedded routines, habits and norms, local conventions of communication and interaction, all of which contribute to a region's particular success. Although these approaches may not deny the forces of the capitalist space economy, they do not explicitly acknowledge them or take them on board and so they tend to discuss non-economic factors and institutions as autonomous forces shaping development. This essay provides a critique of these concepts based on their (1) inadequate theorization, (2) depoliticized view of politics and de-economized use of economics and (3) reduction of space to territory. The essay concludes that we need a far more penetrating renewal of radical critique of the current space economy of capitalism. Old concepts such as uneven development, the social and spatial division of labour, the geographical transfer of value, accumulation and imperialism must be combined with cultural and institutional issues, with those non-economic factors mentioned above.
