Associação entre doença cardiovascular e demência: um estudo clinicopatológico / Association between cardiovascular disease and dementia: a clinicopathological studyClaudia Kimie Suemoto Zoriki 05 February 2010 (has links)
INTRODUÇÃO: Recentemente, fatores de risco cardiovascular (FRCV) e doenças cardíacas têm sido associados à demência, doença de Alzheimer (DA) e demência vascular (DV). O objetivo deste trabalho é investigar a associação entre doença cardiovascular comprovada anatomicamente e demência, definida por critérios clínicos, neuropatológicos e clinicopatológicos. MÉTODOS: Trata-se de estudo transversal com material do Banco de Encéfalos Humanos do Grupo de Estudos em Envelhecimento Cerebral. Aterosclerose de artérias carótidas e do polígono de Willis (PW) e hipertrofia miocárdica foram avaliados em material de autópsia e relacionados à prevalência de demência. Dados demográficos e FRCV também foram comparados quanto à presença de demência. Esta foi definida por três critérios: (1) clínico de acordo com escalas cognitivas aplicadas ao informante do falecido; (2) neuropatológico de acordo com critérios aceitos para a classificação de DA e DV; (3) clinicopatológico de acordo com a avaliação cognitiva e com a presença de lesões cerebrais associadas à DA e DV. RESULTADOS: No estudo clínico, foram incluídos 603 indivíduos maiores de 50 anos de idade com avaliação cognitiva e cardiovascular. Demência esteve associada a obstruções críticas (75%) em artérias carótidas, a menor peso cardíaco e a menor espessura da parede ventricular esquerda. Os portadores de demência definida por critérios clínicos eram mais idosos e apresentaram maior proporção de acidente vascular cerebral (AVC) referido pelo informante, sedentarismo, insuficiência cardíaca e menor índice de massa corpórea do que os indivíduos sem demência. No estudo neuropatológico, foram avaliados 183 indivíduos que se dividiram em três grupos: controles (n=124), portadores de DA (n=31) e DV (n=28). Indivíduos com DA apresentaram maior proporção de obstruções75% em artérias carótidas do que controles. Os portadores de DV, além de maior gravidade da aterosclerose carotídea, também apresentaram maior obstrução em artérias do PW do que controles. Quanto aos dados demográficos e FRCV, a idade foi maior em indivíduos com DA e DV em relação a controles e AVC referido foi mais prevalente entre os portadores de DV. No estudo clinicopatológico, foram incluídos 124 controles, 12 portadores de doença cerebral assintomática (DCA) e 47 dementados. Maior gravidade da aterosclerose carotídea e das artérias do PW foi observada em portadores de demência em relação a controles. Quanto aos dados demográficos e FRCV, indivíduos com DCA e demência eram mais idosos do que controles. A escolaridade de portadores de DCA foi maior do que controles e AVC referido foi mais prevalente entre dementados em relação a controles. CONCLUSÕES: Doença cardiovascular, particularmente aterosclerose de artérias carótidas e do PW, estão associados à maior chance de demência. Medidas preventivas que visem retardar a progressão da aterosclerose podem ser eficientes para diminuir a incidência de demência / INTRODUCTION: Recently, cardiovascular risk factors (CVRF) and cardiac diseases have been associated with dementia, Alzheimer disease (AD) and vascular dementia (VD). The aim of this study was to investigate the association between anatomically-proven cardiovascular disease and dementia, defined by clinical, neuropathological and clinicopathological criteria. METHODS: This was a cross-sectional study using material drawn from the Human Brain Bank of the Aging Brain Study Group. Carotid artery and Circle of Willis (CW) atherosclerosis as well as myocardial hypertrophy were evaluated in autopsy material and compared for the prevalence of dementia. Demographics and CVRF were also compared for the presence of dementia. This was defined by three criteria: (1) clinical according to cognitive scales applied to the informant of the deceased individual; (2) neuropathological according to accepted criteria for the classification of AD; (3) clinicopathological according to cognitive evaluation and the presence of AD and VD-associated cerebral lesions. RESULTS: The clinical study included 603 individuals older than 50 years, who underwent cognitive and cardiovascular evaluation. Dementia was found to be associated with a high degree (75%) of obstruction in carotid arteries, lower heart weight and thinner left ventricle wall. Individuals with clinically-defined dementia were older and had more informant-reported strokes, greater physical inactivity and heart failure and lower body mass index than subjects without dementia. The neuropathological study involved 183 individuals who were evaluated and divided into three groups: control group (n=124), AD (n=31) and VD (n=28). Individuals with AD showed a higher degree of obstruction75% in the carotid arteries than controls. Subjects with VD, besides presenting greater severity of carotid atherosclerosis, also had a greater degree of obstruction in the arteries of the CW than controls. Regarding demographics and CVRF, age was higher in individuals with AD and VD compared to controls, while informant-reported stroke was more prevalent among individuals with VD. The clinicopathological study included 124 control individuals, 12 patients with asymptomatic brain disease (ABD) and 47 demented subjects. Greater severity of carotid and CW artery atherosclerosis was observed in individuals with dementia compared to controls. In terms of demographics and CVRF, individuals with ABD were older than control individuals. Years of education were higher in subjects with ABD compared to controls and informant-reported stroke was more prevalent among demented persons than controls. CONCLUSIONS: Cardiovascular disease, particularly carotid artery and CW atherosclerosis, are associated with higher risk for dementia. Preventive measures aimed at slowing the progression of atherosclerosis may be effective in decreasing the incidence of dementia

Hipertextualidade e relações dialógicas no gênero digital microblog político dos candidatos à presidêcia do Brasil nas eleições 2010 / Hypertextuality and dialogical relationships in the digital micro blog genre of the candidates to the Brazilian presidency in the elections of 2010Artur Daniel Ramos Modolo 14 December 2012 (has links)
O objetivo desta pesquisa é analisar a inter-relação entre as esferas política e do cotidiano no gênero digital microblog político dos candidatos à presidência do Brasil nas eleições de 2010. Como corpus da pesquisa foi arquivado todo o material postado no Twitter pelos três principais candidatos à presidência da república Dilma Rousseff, José Serra e Marina Silva durante o período oficial de campanha (06 de julho de 2010 / 31 de outubro de 2010). Em vista de atingir tais propósitos, elaborou-se a seguinte pergunta de pesquisa: De que forma se dá a inter-relação entre as esferas política e do cotidiano no microblog dos candidatos à presidência do Brasil nas eleições de 2010?Empregaremos como base teórico-metodológica as contribuições do Círculo de Bakhtin. Em um primeiro nível de análise, iremos verificar o contexto social mais amplo que envolve as eleições de 2010. A partir destas reflexões, constatamos as diversas dimensões de relações dialógicas presentes nos enunciados do corpus. Os resultados obtidos por esta pesquisa ilustram a alternância entre mensagens com tom informal que visam aproximar o candidato de seus eleitores, próprio da conversação do cotidiano e dos gêneros primários (simples) e de mensagens densas que aprofundam o debate com teor sociopolítico, isto é, os gêneros secundários (complexos). Deve-se ressaltar que a heterogeneidade do gênero microblog é realçada pelos recursos hipertextuais que criam um conteúdo multimodal: verbal (mensagens de apoio, descrição do dia a dia), visual (fotos, vídeos) e sonoros (jingles, músicas). Avaliamos, em conjunção com a hipertextualidade, as relações dialógicas presentes no corpus: a variação entre concordância, discurso citado, polêmica, objeções, etc. / This research aims at analyzing the interplay between the political and everyday life spheres in the digital micro blog genre of the candidates running for the Brazilian presidential elections in 2010. The main research corpus is an archived compilation of all the material posted on Twitter by the three main candidates running for President in Brazil Dilma Rousseff, José Serra and Marina Silva during the official campaign period (July 6th, 2010 / October 31st, 2010). In order to achieve such propositions, the following research question has been elaborated: How does the interrelationship between the political and everyday life spheres happen in the microblog of the candidates to the Brazilian presidency in the elections of 2010? The contributions of the Bakhtin Circle will be used as the theoretical and methodological basis. In a first analytical level, we will observe the broader social context involving the 2010 elections. Based on these reflections, we have found out the multiple dimensions of the dialogical relationships that are present in the corpus utterances. The results obtained by this research illustrate the alternation between messages with an informal style, aiming at approaching the candidate to his electors, typical of everyday conversations and primary genres (simple), and dense messages that deepen the debate with social-political content, that is, the secondary genres (complex). It must be pointed out that the heterogeneity of the microblog genre is enhanced by hypertext resources that create multimodal content: verbal (support messages, descriptions of everyday life), visual (pictures, videos), and audio (jingles, songs). We evaluated, in conjunction with hypertextuality, the dialogical relationships present in the corpus: the agreement, controversy, quoted speech, polemic, objections, etc.

"Dom tindrar med ögonen" : Förskollärare och barnskötares diskussion om undervisning i samlingen / They ligthen their eyes : Preschool teachers’ discussion about teaching in the circle-timeFarnestam, Marie-louise, Josefsson, Lisa January 2019 (has links)
Till sommaren 2019 börjar den nya Läroplanen för förskolan att gälla. I den skrivs begreppet undervisning fram. Det saknas idag en tydlig definition av begreppet vilket gör att förskollärare känner en osäkerhet kring undervisning. Studiens syfte är därför att utifrån ett didaktiskt perspektiv bidra med kunskap om förskollärare och barnskötares diskussion om undervisning i förskolan. Det sker genom att studera förskollärare och barnskötares tal om möjligheter och begräsningar för lärande i samling i förhållande till de pedagogiska atmosfärerna. De frågeställningar som studien bygger på är: I vilket syfte genomförs samlingar? Hur planerar förskollärare undervisning? och Vad kan möjliggöra och begränsa barns lärande i samlingen? För att samla in data genomfördes tre fokusgrupper med totalt åtta deltagare. Sex deltagare är förskollärare och två är barnskötare. Undersökningen genomfördes på tre olika förskolor. Resultatet visar i huvudsak på att begreppet undervisning är svårtolkat. Förskollärarna och barnskötarna menar att begreppet har diskuterats mycket men att det fortfarande saknas en tydlig definition. Samlingen används inte för undervisning i första hand utan undervisning sker i mindre grupper. Läroplanen ligger till grund för planering. Resultatet visar att förskollärare och barnskötares pedagogiska atmosfär påverkar vilka möjligheter och begränsningar som finns för lärande. Nyckelord: Undervisning, samling, förskollärare, barnskötare, pedagogisk atmosfär

Carnap e a natureza da lógica / Carnap and the nature of logicTranjan, Tiago 28 January 2010 (has links)
Em The Logical Syntax of Language (1937) R. Carnap elabora o seu Princípio de Tolerância Lógica. Trata-se de um princípio lógico-filosófico de grande alcance, que condensa as posições mais consistentes do autor acerca do significado filosófico da pesquisa em lógica formal. A despeito do fracasso do projeto geral de uma filosofia sintática, esse princípio permaneceu como base de todo o pensamento posterior de Carnap. Mais do que isso, influenciou boa parte do melhor trabalho realizado em lógica até hoje, tendo deixado marcas duradouras sobre a filosofia analítica. Neste trabalho, buscamos examinar a origem do Princípio de Tolerância no pensamento de Carnap, como melhor caminho para estabelecer seu significado e implicações. / In The Logical Syntax of Language (1937) R. Carnap develops his Principle of Tolerance in Logic. This is a far-reaching principle for the whole philosophy of logic, and which sums up Carnaps most consistent tenets concerning the philosophical meaning of research in formal logic. Despite the failure of the general project of a syntactical philosophy, the Principle of Tolerance remained the basis for the whole of Carnaps subsequent thought. Moreover, it proved influential in a good deal of the most important work done in logic to this day; it also left permanent traces in analytic philosophy. In this work, we aim at examining the origins of the Tolerance Principle in Carnaps thought, as the best way to establish its significance and implications.

Image Based Social Media and The Tourist Gaze A Phenomenological ApproachJanuary 2019 (has links)
abstract: The emergence of social media in concert with improved camera and cell phone technologies has helped usher in an age of unprecedented visual communication which has radically changed the tourism industry worldwide. Serving as an important pillar of tourism and leisure studies, the concept of the tourist gaze has been left relatively unexamined within the context of this new visual world and more specifically image based social media. This phenomenological inquiry sought to explore how image based social media impacts the concept of the tourist gaze and furthermore to discover how the democratization of the gaze in concert with specific features of image based social media applications impacts the hermeneutic circle of the tourist gaze. This in-depth analysis of the user experience within the context of travel consisted of 19 semi-structured photo elicitation interviews and incorporated 57 participant generated photos. Six salient themes emerged from the study of this phenomenon; 1) sphere of influence, 2) exchange of information, 3) connections manifested, 4) impression management and content curation, 5) replicated travel photography, and 6) expectations. Analysis of these themes in conjunction with examples from the lived user experience demonstrate that the tourist gaze is being accelerated and expanded by image based social media in a rapid manner. Furthermore, democratization of the gaze as enabled by technological developments and specialized social media platforms is actively shifting the power role away from a small number of mass media influencers towards a larger number of branded individuals and social media influencers. Results of this inquiry support the theoretical assertions that the tourist gaze adapts to social and technological developments and demonstrates that the concept of the tourist gaze is increasingly important within tourism studies. Practical implications regarding the prevalence of real-time information, site visitation, and “taking only pictures” as sustainable touristic behavior are discussed. / Dissertation/Thesis / Masters Thesis Community Resources and Development 2019

The Solenoid and Warsawanoid Are Sharkovskii SpacesHills, Tyler Willes 01 December 2015 (has links)
We extend Sharkovskii's theorem concerning orbit lengths of endomorphisms of the real line to endomorphisms of a path component of the solenoid and certain subspaces of the Warsawanoid. In particular, Sharkovskii showed that if there exists an orbit of length 3 then there exist orbits of all lengths. The solenoid is the inverse limit of double covers over the circle, and the Warsawanoid is the inverse limit of double covers over the Warsaw circle. We show Sharkovskii's result is true for path components of the solenoid and certain subspaces of the Warsawanoid.
