Its empirical part focuses on the exam of the performance persistence phenomenon for actively managed funds from July 1996 to June 2001. The active equity funds (whose benchmark is the Ibovespa Index) presented superior returns relative to the Ibovespa Index and to the indexed Ibovespa funds (passive funds). The study presents confirming evidence of the performance persistence phenomenon for the entire sample, for the high volatility and the low volatility groups. Strategies of investing in the top performance funds proved to be efficient during the entire period (except for investment in the 10% and 20% lower performance funds considering annual holding periods). The fixed income funds achieved lower return in relation to the COI (Brazilian fixed income benchmark) and to the COI indexed funds. However, that category of funds presented the greatest degree of performance persistence. Ali strategies of investing in the top performance funds returned better than the investment in the lower performance funds. The multimarket funds (hedge funds) achieved superior return relative to the COI but presented the weaker indication of performance persistence in the period. The investment strategy to buy bottom performers yielded better results than the investment in the top funds. The strategy of investing in the top 20% funds rated according to the Generalized Sharpe Index achieved superior return than those based on a strategy of investing according to a raw return ranking unadjusted for risk. / O presente trabalho apresenta um resumo não só dos conceitos básicos sobre fundos de investimento, como também seu histórico e evolução no Brasil e no mundo, o contexto institucional nacional e os principais ratings de classificação de performance. Sua parte empírica foca-se no exame do fenômeno de persistência de performance para os fundos de investimentos ativos brasileiros entre julho de 1996 e junho de 2001. O estudo empírico dividiu-se em três partes: a comparação do retomo das categorias de fundos de ações ativos, de renda fixa e multimercados com os respectivos benchmarks e fundos passivos; a verificação do fenômeno de persistência baseando-se em Malkiel (1995); e a análise dos resultados de investimentos em portfólios formados pelos grupos de uma mesma categoria pertencentes a um mesmo percentil de retomo não ajustado ao risco. Os fundos de ações ativos com benchmark no Ibovespa apresentaram retornos médios superiores ao Ibovespa e aos fundos indexados ao Ibovespa (fundos passivos). Verificaram-se o fenômeno de persistência de performance para a amostra total, grupos de alta volatilidade e baixa volatilidade para períodos de investimento semestrais, anuais e de 2,5 anos. Estratégias de investimento em grupos dos melhores fundos apresentaram, de maneira geral, retornos simples (líquidos de taxa de administração) superiores à média do retomo de todos os fundos de ações ativos analisados. Entretanto houve exceções para as médias dos 10% e 20% piores fundos (quando analisados para períodos de investimento de 1 ano). Os fundos de renda fixa obtiveram retornos inferiores ao CDI e aos fundos referenciados DI. Entretanto, verificou-se, nessa categoria, a maior evidência estatística de persistência de performance. Todas as estratégias de investimentos, nos melhores fundos do período anterior, mostraram-se eficientes. Os fundos multimercados conseguiram superar o retomo do CDI e apresentaram o menor grau de evidência de persistência de performance. A estratégia de investimento em vencedores do período anterior obteve retornos inferiores ao investimento nos grupos de pior desempenho anterior, em todos os períodos analisados. A estratégia de investimento baseada nos melhores fundos classificados de acordo com o Índice de Sharpe Generalizado, mostrou-se mais eficiente que a baseada, exclusivamente, na classificação dos fundos por retomo bruto não ajustado para risco.

A lavagem das mãos é reconhecida como uma das medidas mais importantes para prevenir as Infecções Hospitalares. Este estudo teve como objetivo comparar a execução e verificar a adesão aos passos da técnica de lavagem das mãos por alunos dos 2º, 3º e 4º anos de um Curso de Graduação em Enfermagem. A amostra constituiu-se de 113 alunos que estavam cumprindo estágio em instituições de saúde do município de São Paulo. Os dados foram coletados por meio de observação direta para a qual foi utilizado um instrumento em forma de “check-list” com os passos da técnica de lavagem das mãos, conforme recomendação do Ministério da Saúde do Brasil. Os resultados foram estatisticamente trabalhados, permitindo constatar que: a) os alunos dos 2º e dos 3º anos obtiveram melhor desempenho na execução da técnica de lavagem das mãos, com diferença estatisticamente significante, quando comparados ao 4º ano nos passos da técnica: “retirou jóias”, “esfregou palma com dorso”, “esfregou espaços interdigitais”, “esfregou polegar” e “esfregou unhas”. Apenas no item “fechou a torneira com papel toalha” o 4º ano apresentou-se melhor que os 2º e 3º anos; b) a adesão aos passos da técnica de lavagem das mãos dos alunos de todos os anos do curso foi muito baixa, pois na metade dos passos que compõe a técnica, os alunos apresentaram adesão menor que 50%; c) A porcentagem de alunos que executou TODOS OS PASSOS da técnica de lavagem das mãos CORRETAMENTE foi muito baixa, apenas 8,8%. Concluiu-se que os alunos do 4º ano obtiveram o pior desempenho e adesão muito baixa em quase todos os passos da técnica de lavagem das mãos, quando comparados aos dos 2º e 3º anos / Handwashing is known as one of the most important measures in preventing hospital-acquired Infections. This study had the objective of comparing the performance and verifying the adhesion of students from the 2nd, 3rd and 4th years of the Graduation nursing course to the steps of this technique. The sample was made of 113 students who were under the internship program in health institutions in the city of Sao Paulo. The data were collected through unobtrusive observation based on an instrument in a check-list form with all the steps of the hands-washing technique, as suggested by the Brazilian Health Ministry. The results were statistically treated showing that: a) the students from the 2nd and 3rd years had better results in the execution of the handwashing technique, with a significant statistical difference, when compared to the students from the 4th year considering the steps: “jewelry-removing”, “rubbed the palm of the hand with its back”, ”rubbed spaces between fingers”, “rubbed thumb” and “rubbed nails”. Considering the item “closing the faucet with a paper towel” the students from the 4th year were better than the ones from the second and third years; b) the students from all years of graduation the 2nd, 3rd and 4th years showed low adhesion to the hands-washing technique steps, once they presented the adhesion to less than 50% of the steps; c) The percentage of students who performed ALL THE STEPS of the handwashing technique CORRECTLY was very low, only 8.8%. It was concluded that the students from the 4th years in almost all had the worst performance and the lowest adhesion to the hands-washing technique when compared to the students from the 2nd and 3rd years

The purpose of this study was to explore how students described the curriculum in the Introduction to Food Production class and how they perceived the curriculum prepared them for their future in the hospitality industry. The exploratory questions that guided the study were how do students describe the experiential learning curriculum in the Introduction to Food Production course, what ways do students perceive the curriculum in the Introduction to Food Production course prepares them for their future in hospitality industry, and what changes in the curriculum do students think might improve the Introduction to Food Production course and why? The theoretical framework for this study was based on Kolb’s experiential learning theory model (1984). Data collection methods were semi-structured interviews, student journals, and a researcher reflection journal. The cross-case analysis generated nine major themes: hands-on basics taught by professionals, memorable curriculum with useful application, challenging group work forced students to develop diverse insights, well designed facility for learning, gained confidence through memorable moments, observed industry best practices for success, connected to real world with hands-on methods, managerial skills needed for success in the future, and students desire more educational elements to the course and program. These nine themes summarize the students’ experiences in a hands-on teaching facility at the University of South Florida Sarasota-Manatee. Implications for practitioners and policy makers were described. Results of this study contributed empirical research on experiential learning theory and hospitality program curriculum. These results also add to the body of literature related to hands-on teaching activities, group work assignments, and industry-based projects.

Segmenting image into multiple meaningful regions is an essential task in Computer Vision. Deep Learning has been highly successful for segmentation, benefiting from the availability of the annotated datasets and deep neural network architectures. However, depth-based hand segmentation, an important application area of semantic segmentation, has yet to benefit from rich and large datasets. In addition, while deep methods provide robust solutions, they are often not efficient enough for low-powered devices. In this thesis, we focus on these two problems. To tackle the problem of lack of rich data, we propose an automatic method for generating high-quality annotations and introduce a large scale hand segmentation dataset. By exploiting the visual cues given by an RGBD sensor and a pair of colored gloves, we automatically generate dense annotations for two-hand segmentation. Our automatic annotation method lowers the cost/complexity of creating high-quality datasets and makes it easy to expand the dataset in the future. To reduce the computational requirement and allow real-time segmentation on low power devices, we propose a new representation and architecture for deep networks that predict segmentation maps based on Voronoi Diagrams. Voronoi Diagrams split space into discrete regions based on proximity to a set of points making them a powerful representation of regions, which we can then use to represent our segmentation outcomes. Specifically, we propose to estimate the location and class for these sets of points, which are then rasterized into an image. Notably, we use a differentiable definition of the Voronoi Diagram based on the softmax operator, enabling its use as a decoder layer in an end-to-end trainable network. As rasterization can take place at any given resolution, our method especially excels at rendering high-resolution segmentation maps, given a low-resolution image. We believe that our new HandSeg dataset will open new frontiers in Hand Segmentation research, and our cost-effective automatic annotation pipeline can benefit other relevant labeling tasks. Our newly proposed segmentation network enables high-quality segmentation representations that are not practically possible on low power devices using existing approaches. / Graduate
