L’imaginaire sonore de l'arrière-pays grenoblois : sur les pistes d'une sonographie non exhaustive

L'imaginaire est ce qui nous fonde, nous homo-sapiens. C'est grâce à cet infini balancement entre des représentations tant objectives (admises culturellement), que subjectives (de l'ordre de la perception du réel), que nous sommes capables de modifier durablement notre environnement proche selon la réalité à laquelle nous souhaitons croire. Mais qu'en est-il de l'ère anthropocène qui se caractérise justement par l'impact de notre existence sur la biosphère ? L'objectif de ce mémoire se porte sur l’intérêt de réactiver les paysages sonores d'un lieu à tendance anthropique qu'est l'arrière-pays grenoblois, afin de mieux comprendre dans quelles représentations ces sonorités s'inscrivent

Barreiras percebidas à prática de atividade física e sua relação com fatores sociodemográfico, ambientais e comportamentais em idosos

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2023.A atividade física é amplamente reconhecida como uma estratégia fundamental para a saúde da população idosa, mas a inatividade física tem aumentado devido diversos fatores, como a falta de acesso a programas de atividade física e de locais adequados e seguros para realizar essa prática. Nesse contexto, este estudo tem como objetivo geral investigar as barreiras percebidas à prática de atividade física e sua relação com fatores sociodemográficos, ambientais e comportamentais entre idosos residentes em Florianópolis, Santa Catarina. Este estudo transversal utilizou dados da pesquisa \"Condições de Saúde da População Idosa do Município de Florianópolis, SC: Estudo de Coorte de base populacional (EpiFloripa Idoso 2017-2019)\", na qual 1.335 idosos foram entrevistados. Para análise, foram incluídos apenas os participantes com informações completas sobre as variáveis investigadas, totalizando 1.187 idosos. Para avaliar as barreiras à prática de atividade física, foi aplicada uma escala com 20 itens. Para coletar informações sobre a atividade física dos idosos, incluindo caminhada, foi registrado o tempo acumulado em minuto/semana seguindo a adaptação do International Physical Activity Questionnaire (IPAQ) longo para idosos. As variáveis sociodemográficas, incluíram sexo, idade e escolaridade. Para avaliar os fatores ambientais, medida objetiva, como o walkability, e subjetiva, como a percepção do ambiente foi utilizada, por meio da escala adaptada Neighborhood Environment Walkability Scale - Abbreviated (A-NEWS). Os dados foram tabulados no Microsoft Excel e no Statistical Package for the Social Sciences para análises descritivas e psicométricas (confiabilidade e validação fatorial). O software MPlus versão 8.0 foi utilizado para análise fatorial confirmatória e modelagem de equações estruturais. Utilizando o estimador WLSMV (Weighted Least Square Mean and Variance Adjusted) como estimador do modelo para barreiras percebidas, obtendo um ajustamento bom (X2/df = 363.34; CFI = 0,98; TLI = 0,87; RMSEA = 0.04; P [rmsea=0.05] 1.0; SRMR = 0.06). Na escala de ambiente percebido da vizinhança utilizando o mesmo estimador obtendo um ajustamento bom (X2/df = 337.65; CFI = 0,95; TLI = 92; RMSEA = 0.09; P [rmsea=0.05] 0,001; SRMR = 0,98). O modelo final apresentou um ajuste adequado para as estimativas propostas, e os resultados indicaram que um aumento no escore da escala de barreiras percebido como resultado em uma diminuição de 29 minutos/semana de atividade física no lazer entre os idosos. Além disso, a maior escolaridade associada à maior prática de atividade física de lazer, enquanto as mulheres apresentavam maior percepção de barreiras. Este estudo identificou as diferentes relações entre barreiras percebidas com as variáveis de ambiente, sociodemográficas e comportamentais, indicando a necessidade de que as políticas públicas voltadas para a promoção de atividades físicas considerem, os atributos do ambiente construído, características da população, contexto local, socioeconômico e desigualdades. Assim, este estudo tem potencial de subsidiar a estruturação de políticas públicas que integrem planejamento urbano, mobilidade, saúde e bem-estar da população idosa fomentando a prática de atividade física como ferramenta para a promoção de um modo de vida mais saudável e ativo.Abstract: Physical activity is recognized as a important strategy for the health of older adults, but physical inactivity has increased due to various factors, such as lack of access to physical activity programs and suitable and safe places to engage in this practices. In this context, this study aims to investigate the perceived barriers to physical activity and their relationship with sociodemographic, environmental, and behavioral factors among older adults residing in Florianópolis, Santa Catarina. This cross-sectional study used data from the \"Health Conditions of the Older Adults Population of the Municipality of Florianópolis, SC: Population-based Cohort Study (EpiFloripa Aging 2017-2019)\" research, in which 1,335 older adults were interviewed. For the analysis, only participants with complete information on the investigated variables were included, totaling 1,187 older adults. To assess the barriers to physical activity, a 20-item scale was applied. To collect information on the physical activity of older adults, including walking, the accumulated time in minutes per week was recorded following the adaptation of the International Physical Activity Questionnaire (IPAQ) long version for older adults. The sociodemographic variables included sex, age, and education level. To assess environmental factors, objective measures such as walkability, and subjective measures such as perception of the environment were used, through the adapted Neighborhood Environment Walkability Scale - Abbreviated (A-NEWS). The data were tabulated in Microsoft Excel and the Statistical Package for the Social Sciences for descriptive and psychometric analyses (reliability and factor validation). The MPlus version 8.0 software was used for confirmatory factor analysis and structural equation modeling. Using the WLSMV (Weighted Least Square Mean and Variance Adjusted) estimator as the model for perceived barriers, a good fit was obtained (X2/df = 363.34; CFI = 0.98; TLI = 0.87; RMSEA = 0.04; P [rmsea=0.05] 1.0; SRMR = 0.06). For the perceived neighborhood environment scale using the same estimator, a good fit was also obtained (X2/df = 337.65; CFI = 0.95; TLI = 0.92; RMSEA = 0.09; P [rmsea=0.05] 0.001; SRMR = 0.98). The final model showed an adequate fit for the proposed estimates. The results indicated that an increase in the perceived barriers scale score resulted in a decrease of 29 minutes per week of leisure physical activity among older adults. Additionally, higher education was associated with greater leisure physical activity, while women showed a higher perception of barriers. This study identified the different relationships between perceived barriers and environmental, sociodemographic, and behavioral variables, indicating the need for public policies aimed at promoting physical activities to consider attributes of the built environment, population characteristics, local context, socioeconomic status, and inequalities. Thus, this study has the potential to support the structuring of public policies that integrate urban planning, mobility, health, and well-being of older adults, promoting physical activity as a tool for promoting a healthier and more active lifestyle

Les sirènes du Drac - garages de l'ENSAG

Si l'on se promène à proximité du Drac ou des collines environnantes dans le sud de la métropole grenobloise, d'étranges sirènes se font entendre à quatre moments très précis de l'année. Aux sirènes du premier mercredi du mois, dont la plupart nous est familier, s'ajoutent ici chaque trimestre des exercices d'alerte liées aux activités industrielles locales : les barrages hydro-électriques et les plateformes chimiques. Ces sirènes sont l'un des moments où ce territoire tissé d'industries et de géographie se fait entendre comme une construction fragile qui pourrait se défaire à tout moment ; l’objectif est d'installer les bons réflexes face à cet effondrement potentiel.A partir d'une prise de son collective et simultanée en cinq points de ce paysage, l'installation des « sirènes du Drac » donne à entendre les résonances de cet arrière-pays grenoblois. Une composition prend forme qui met en dialogue l'espace de la prise de son (le territoire sud grenoblois) et l'espace de diffusion. Ici, il s'agit d'un espace intérieur, les garages au sous-sol de l'école d'architecture de Grenoble. Cette diffusion a eu lieu à l'occasion de la journée d'étude « Sensible et transformations socio-écologiques des milieux de vie » organisée par le laboratoire Ambiances, Architectures, Urbanités (AAU, UMR 1563).Cette installation s'inscrit dans le cadre d'une recherche doctorale sur « les ambiances de l'anthropocène », au sein du projet ANR Sensibilia

Determination of 3‑Monochloropropane-1,2-diol and 2‑Monochloropropane-1,3-diol (MCPD) Esters and Glycidyl Esters by Microwave Extraction in Different Foodstuffs

This paper describes a method for the determination of 3-monochloropropane-1,2-diol and 2-monochloropropane-1,3-diol (MCPD) esters and glycidyl esters in various foodstuffs, which are isolated using microwave extraction. The next step is based on alkaline-catalyzed ester cleavage. The released glycidol is transformed into monobromopropanediol (MBPD). All compounds are derivatized in free diols (MCPD and MBPD) with phenylboronic acid and analyzed by gas chromatography–mass spectrometry (GC–MS). The method was validated for oils with a limit of quantitation (LOQ) of 0.1 mg/kg, for chips and crisps with a LOQ of 0.02 mg/kg, and for infant formula with a LOQ of 0.0025 mg/L. Recoveries of each sample were controlled by standard addition on extracts before derivatization. Quantitation was performed by the addition of isotopically labeled glycidyl and 3-monochloropropane-1,2-diol (3-MCPD) esters

Recovering Ga(III) from coordination complexes using pyridine 2,6-dicarboxylic acid chelation ion chromatography

The definitive version can be found at: http://onlinelibrary.wiley.com/ Copyright John Wiley & Sons, Ltd. [Full text of this article is not available in the UHRA]Ion exchange chelation chromatography is an effective means to extract metals from coordination complexes and biological samples; however there is a lack of data to verify the nature of metal complexes that can be successfully analysed using such a procedure. The aim of this study was to assess the capability of pyridine 2,6-dicarboxylic acid (PDCA) to extract and quantify Ga(III) from a range of environments using standard liquid chromatography apparatus. The PDCA chelation method generated a single Ga(III) peak with a retention time of 2.55 +/- 0.02 min, a precision of 15. Copyright (C) 2010 John Wiley & Sons, Ltd.Peer reviewe
