No. of bitstreams: 1 osvaldoVOLUME FINAL MESTRADO.pdf: 815651 bytes, checksum: 90a8377db285a55fd7b423e263495036 (MD5) Previous issue date: 2011-10-06 / Abstract Objective: To describe the prevalence of physical inactivity among users of Psychosocial Care Centers of Pelotas and investigate factors associated. Methods: A cross-sectional design nested in a prospective cohort study among users of CAPS Pelotas / RS. We used a standardized questionnaire containing questions precoded. The dependent variable was physical inactivity during leisure time as measured by the International Physical Activity Questionnaire (IPAQ questionnaire) in the short version. We used the chi-square test to compare proportions with a significance level of 5%. Multivariate analysis using Poisson Regression was conducted to adjust the effect of potential confounding factors. Results: The prevalence of inactivity in the sample was 61% (95% CI 57-64) without differences in relation to gender (p < 0.423), skin color (p < 0.763), family income (p < 0.943) , smoking (p < 0.670), with alcohol dependence (p < 0506), and participation in groups (p < 0.153) and workshops (p < 0.567). There was no significant variation in the prevalence of sedentary lifestyle according to the type of disorder. Compared with younger people, older people had a higher prevalence of physical inactivity (p < 0.015 T) and lower educational level, higher prevalence of physical inactivity (p < 0.004 T). Compared with whom he was working, people who had never worked for almost 60% higher prevalence of physical inactivity (p < 0.003). With the adjustment, age lost significance (p < 0.130) and remained strongly associated with sedentary the less educated (p < 0.029), the fact of not working (p < 0.000), presence of cognitive impairment (p < 0.000) and worse self-rated health status (p < 0.000). Conclusion: Physical inactivity is associated with less schooling, the fact of not working, the presence of cognitive impairment and poorer health perception / Objetivo: Descrever a prevalência de sedentarismo entre usuários de Centros de Atenção Psicossocial de Pelotas e investigar fatores associados. Métodos: Estudo de delineamento transversal aninhado à uma coorte prospectiva entre os usuários dos CAPS de Pelotas/RS. Utilizou-se um questionário padronizado contendo questões pré-codificadas. A variável dependente foi o sedentarismo no lazer, avaliado através do Questionário Internacional de Atividade Física (IPAQ) na versão curta. Foi utilizado o teste qui-quadrado para a comparação entre proporções com nível de significância de 5%. Análise multivariada por regressão de Poisson foi conduzida a fim de ajustar o efeito para potenciais fatores de confusão. Resultados: A prevalência de sedentarismo na amostra foi de 61% (IC95% 57-64), sem diferenças em relação ao gênero (p<0,423), à cor da pele (p<0,763), à renda familiar (p<0,943), ao tabagismo (p<0,670), à dependência de álcool (p<0506), e à participação em grupos (p<0,153) e oficinas (p<0,567). Não houve variação significativa na prevalência de sedentarismo conforme o tipo de transtorno. Comparados com os mais jovens, os mais velhos tiveram maior prevalência de sedentarismo (p<0,015T )e quanto menor a escolaridade, maior a prevalência de sedentarismo (p<0,004T). Comparados com quem estava trabalhando, as pessoas que nunca trabalharam tiveram quase 60% maior prevalência de sedentarismo (p<0,003). Com o ajuste, a idade perdeu significância (p<0,130), tendo permanecido fortemente associados ao sedentarismo a menor escolaridade (p<0,029), o fato de não trabalhar (p<0,000), a presença de déficit cognitivo (p<0,000) e a pior percepção da situação de saúde (p<0,000). Conclusão: Sedentarismo está associado com a menor escolaridade, o fato de não trabalhar, a presença de déficit cognitivo e pior percepção de saúde Legenda: T= p valor de tendência linear

Seasonal Polar Carbon Dioxide Frost on Mars: Spatiotemporal Quantification of CO2 Utilizing 2001 Mars Odyssey Gamma Ray Spectrometer Data

Kelly, Eleanor Jane January 2006 (has links)
The exchange of carbon dioxide between the atmosphere and the polar caps on Mars creates a seasonal cycle of growth and retreat of the polar caps. As the major component of the Martian atmosphere, CO2 condenses in the polar regions of the planet during the winter seasons and precipitates as CO2 frost. It then sublimes during the spring and summer seasons in response to solar radiation. Through natural radioactivity or when exposed to cosmic rays, elements in the Martian near-subsurface (uppermost meter) emit gamma rays with distinct, characteristic energies. The Gamma Ray Spectrometer (GRS) onboard the 2001 Mars Odyssey satellite is used to measure the gamma rays coming from the Martian regolith to calculate elemental distributions, abundances, and temporal variations in the gamma ray flux. Changes in the CO2 frost over time can be quantified by observing attenuation effects of H (2223 keV hydrogen) and 40K (1461 keV potassium) gamma ray signals transmitted through various depths of polar CO2 overburden throughout the Martian seasons.Conclusions are drawn about the spatial extent, column density, and mass of Mars' seasonal polar caps as a function of time utilizing GRS data. Columnar thickness and mass results are discussed and plotted for latitudes including +/-60 degrees and poleward. GRS observations are compared to predictions from the NASA Ames Research Center Mars General Circulation Model (ARC GCM) and to similar experimental results from the Mars Odyssey High Energy Neutron Detector (HEND) and the Neutron Spectrometer (NS). Models for north and south polar atmosphere and regolith distributions are incorporated, and the results indicate that the assumption of a 100% H2O-ice residual cap underlying the seasonal frost in the north is accurate. The GRS CO2 frost observations are in good agreement with the other studies mentioned, in particular for the timing of the beginning of frost deposition to the complete sublimation of surface CO2 back into the atmosphere. The total amount of condensed CO2 mass derived from GRS data is on the order of 6.0 x 10^15 kg and verifies previous reports that ~25% of the total Martian exchangeable-CO2 reservoir participates in the ground-atmosphere cycle.

Diretrizes para projeto de blocos de concreto armado sobre estacas. / Design guidelines for piles caps of reinforced concrete.

Letícia Marchiori de Oliveira 16 January 2009 (has links)
Blocos sobre estacas ou blocos de coroamento são elementos estruturais usados para transferir as ações da superestrutura para um conjunto de estacas. São encontrados em infra-estruturas de pontes e edifícios. O conhecimento de seu real comportamento estrutural é de fundamental importância, pois são elementos estruturais que garantem a segurança de toda a estrutura. Ainda não há consenso no meio técnico quanto ao seu real comportamento estrutural; também não se sabe a real forma geométrica das bielas de compressão no Estado Limite Último para a aplicação do método biela-tirante, e falta normalização deste elemento estrutural; estes são alguns aspectos que tornam este trabalho necessário. Com o objetivo de contribuir para diretrizes de projeto, foram apresentados os critérios utilizados nos projetos de blocos sobre estacas e desenvolvido, por meio de resultados de modelos analíticos, um método para a verificação da tensão de compressão na biela junto ao pilar. Nos modelos adotados variaram-se os diâmetros de estacas e dimensões de pilar. Conclui-se que os resultados são de grande relevância, pois os resultados obtidos mostraram-se muito coerentes por serem constantes em função da quantidade de estacas e da relação x/d. / Piles caps are structural elements used to transfer actions of the superstructure to a group of piles. They are found in infrastructures of bridges and buildings. The knowledge of its real structural behavior presents fundamental importance, once piles caps are structural elements that guarantee the safety of all structure. There is no consensus yet between specialists on its real structural behavior, the real geometric shape of the struts on the ULS for the application of the strut-and-tie model its not know, and the lack of standardization of this structural element are some of the aspects that makes this work necessary. With the objective to contribute to the design guidelines, were presented the criteria used in projects of piles caps and developed through results of analytical models, a method for checking the compressive stress at the strut near the column. Piles diameters and column dimensions of the models were been varied. It was concluded that the results are of great relevance, because the values obtained proved to be very consistent since they are in depending on the amount of piles and the relationship x/d.

Para o desenvolvimento da temática proposta, buscou-se embasamento na Teoria das Representações Sociais, de Serge Moscovici. Trata-se de uma pesquisa pluri-metodológica, possibilitando a escolha de variados recursos de coleta e análise de dados para seu desenvolvimento. Os sujeitos da pesquisa foram profissionais de saúde mental que trabalham em CAPS AD: médicos clínicos, psiquiatras, psicólogos, assistentes sociais, terapeutas ocupacionais e enfermeiros. A coleta de dados ocorreu em duas etapas: primeiramente foi realizada a transcrição e análise da evolução técnica de 68 prontuários de usuários de crack admitidos em um CAPS Ad da região metropolitana do Recife no período de janeiro de 2008 a janeiro de 2009. Na segunda etapa, utilizou-se associação livre através de um questionário que foi respondido por 70 profissionais. A análise dos prontuários foi realizada com o suporte do software ALCESTE. A Classificação Hierárquica Descendente fez emergir seis classes, denominadas de: anamnese, riscos à saúde, dificuldades de abstinência, estratégias para manter-se abstêmio, reconquista da família e relato das perdas. Os questionários de evocação foram analisados com recurso do software EVOC (Ensemble de ProgrammesPermettantl’AnalysedesÉvocations), que permitiu delinear a estrutura das representações sociais a partir de três grupos semânticos: usuário,definição de crack e consequências de uso. No que se refere às justificativas dos questionários surgiram os seguintes grupos semânticos: crack e saúde, dependência e sofrimento e problema de política pública. Tais resultados sugerem que os participantes concretizam suas práticas tendo como referência as orientações da política de saúde, entretanto, embora com menor frequência, estão presentes discursos que expressam o medo dos técnicos na medida em que colocam o usuário no campo moral ou da justiça baseados em noções do senso comum que classificam os usuários de crack num lugar estigmatizado, marginalizado

Uma delas foi a criação de serviços substitutivos, como é o caso dos CAPS. Outra dessas mudanças é a reinserção dessas pessoas com sofrimento psíquico no meio familiar. Os CAPS tem como um de seus objetivos reconstruir e estreitar esses laços. No entanto, a Reforma Psiquiátrica e suas implicações nem sempre são bem quistas pelas famílias, e é essa questão que este trabalho se propôs investigar: como é a relação família e sofrimento psíquico em discursos de familiares de usuários de um CAPS da cidade do Recife. Para isso realizamos, durante o período de março a setembro, um grupo focal e entrevistas narrativas com quatro familiares, cada um deles representante de um usuário do CAPS Casa Forte. Os usuários estavam em tratamento na instituição e tinham histórico de internamento em clínica/hospital fechado. É importante ressaltar que o CAPS em questão é particular e os sujeitos da pesquisa pertencem à classe média brasileira e possuem segundo grau completo. Para analisar os discursos construídos pelos sujeitos e seus efeitos, utilizamos a análise de discurso, da Psicologia Social Discursiva. Apesar dos entrevistados usarem termos e expressões próximos àqueles usados na literatura da Reforma Psiquiátrica, eles colocam a pessoa em sofrimento psíquico como incapaz, sem autonomia e sem responsabilidade pelos seus atos. Constatamos também, que os sujeitos entrevistados descrevem a dinâmica familiar como muito penosa e responsabilizam, explicitamente ou implicitamente, o membro da família com sofrimento psíquico por esse clima familiar. Nas suas construções discursivas, os familiares colocam o CAPS como um lugar que alivia a sobrecarga da família causada pelo sofrimento psíquico. Um lugar de ocupação e lazer para os usuários. Colocando, do outro lado, as clínicas particulares como lugar desumano, que transformam seus familiares em seres inanimados, sem vida. Observamos que, apesar dos familiares entrevistados terem um conhecimento dos princípios e valores veiculados pela Reforma Psiquiátrica, eles trazem no seu discurso dificuldades de aceitação do sofrimento psíquico, ora por desconhecer profundamente o sofrimento, ora pela dificuldade em lidar com o comportamento de seus familiares. Observamos, portanto, a importância dos serviços substitutivos, nesse caso os CAPS, em estimular cada vez mais a família no tratamento psiquiátrico, promovendo atividades na instituição que visam estreitar ainda mais os laços ainda existentes das famílias.

Learner perceptions of Life Sciences as a daily life and scientific human challenge

Ali, Yemisi Deborah January 2019 (has links)
In the current knowledge era, learners, as the future of our world, require both knowledge and skills and a moral sense and values. The world is beset with diverse and evolving challenges fundamentally related to Life Sciences, which require certain skills and virtues that are not emphasised by current educational practice in schools. My quest to discover the ultimate consequences of learners’ Life Science learning within the context of the existing prescribed Life Sciences Curriculum and Assessment Policy Statement (CAPS) was prompted by my personal experience as a high school learner and my desire to see learners have rewarding and relevant educational experiences. Although the CAPS of the South African Department of Basic Education aims at providing a link between Life Sciences in the classroom and its everyday application in learners’ lives, in practice it does not seem to achieve its purpose of equipping Life Science learners to be independent problem solvers of life challenges, as stated in its aims. This qualitative case study explored learners’ perceptions of Life Sciences as an essential factor for everyday life and scientific human challenge. The perceptions of 12 purposively selected learners from Grades 8–12 were explored by using semi-structured interviews, open-ended questionnaires, non-participant and quasi-participant observations, elicited materials, and field observation as data collecting instruments. The transcripts of the semi-structured interviews and open-ended questionnaires were analysed using constant comparative analysis while data from the other instruments were used in corroborating or refuting the data from the semi-structured and open-ended questionnaire. The findings indicate that learners perceive their life science learning as only for academic progress with just a few indicating a desire to pursue a science-based university degree. Furthermore, learners did not see Life Sciences as useful for application in their day-today life. However, with the learning of human anatomy, the participants assumed, somehow, that it would be necessary to understand how their body works, but not to the extent of applying the knowledge in their daily lives and decision making. In this regard the Life Sciences curriculum fails to prepare learners to acquire the attributes required to successfully function in the 21st century. / Thesis (PhD)--University of Pretoria, 2019. / Humanities Education / PhD / Unrestricted

An Evaluation of the Social Validity of the Center for Advanced Professional Studies (CAPS) Program

Watt, Jason L. 01 December 2018 (has links)
The Center for Advanced Professional Studies (CAPS) programs are emerging high school programs emphasizing immersive, real-life professional experiences for students. CAPS programs endeavor to facilitate student-centered partnerships between business and public education to produce personalized learning experiences for students centered around the completion of real-world industry projects. To ensure successful educational programs, leaders must consider more than simple outcome data or statistical descriptions of the program’s reliability and validity. Successful leaders of schools must also determine the program’s value from the perspective of the stakeholders it purports to serve—that is, by its social validity. Understanding what consumers of education do and do not find valuable is crucial when developing, implementing, and evaluating educational programs. Unfortunately, this type of evaluation is seldom utilized and has resulted in a nearly inaudible stakeholder voice in public education and its programs. This study evaluated the dimensions of social validity associated with the CAPS program from the perspective of both students and industry partners as consumers. Social validity data was collected via a modified Behavior Intervention Rating Scale (BIRS). Participants were asked to rate CAPS programs by agreeing or disagreeing with each of 20 BIRS statements. Respondents included 459 students and 107 industry partners from twelve CAPS programs in six states. Data from both students and industry partners were analyzed to determine the social validity of CAPS programs. Both students and industry partners rated CAPS programs impressively high on both its acceptability and its effectiveness. CAPS programs are well-positioned to continue to provide positive educational outcomes and experiences to both students and industry partners.

Laterally Loaded Pile Cap Connections

Stenlund, Tony Eugene 16 July 2007 (has links) (PDF)
There is presently considerable uncertainty regarding appropriate connection details between driven piles and pile caps. Prior research on the subject suggests that given a proper embedment length, a specialized reinforced connection may not be necessary. Eliminating these costly connection details could save thousands of dollars on both labor and materials. This research study focuses on the importance of the pile-to-cap connection detail with respect to the reinforcement connection and pile embedment length. Four pile caps were constructed, each with two 40 foot-long steel pipe piles, and were tested with different connection details. Two caps included a reinforced connection detail while the other two relied on their respective embedment lengths. A hydraulic ram was used to apply a cyclic lateral force to each of these pile caps until failure occurred. Load-displacement curves were developed for each pile cap and strain gauge measurements were used to evaluate tension and bending moments in the pile caps. Comparisons are presented regarding the effect of the connection on pile cap response. An analysis has been conducted to best understand possible failure modes; two computer modeling programs were used and their respective results have been presented and compared to the observed readings. This thesis provides test data supporting the theory that a proper embedment length acts as an adequate connection in place of a specialized reinforced detail. A pile cap with piles embedded two diameters into the cap performed successfully. In contrast, a cap with piles embedded only one diameter failed after developing a large crack through the entire cap. For the two pile caps with a reinforcing cage connection; the performance was essentially the same for the piles embedded either six inches (.5 diameter) or twelve inches (one diameter) into the cap. The data produced was found to be very similar to what was estimated by the two programs used for analysis (GROUP 4.0 and LPILE 4.0).
