    Trabalho apresentado no 31¬ļ SEURS - Semin√°rio de Extens√£o Universit√°ria da Regi√£o Sul, realizado em Florian√≥polis, SC, no per√≠odo de 04 a 07 de agosto de 2013 - Universidade Federal de Santa Catarina.O Projeto ‚ÄúBacatelas Navegando nas √Āguas do Conhecimento: Promovendo Sa√ļde em Hortos Terap√™uticos‚ÄĚ consiste na cria√ß√£o e manuten√ß√£o de hortos terap√™uticos em Unidades de Sa√ļde. Est√° integrado ao programa ‚ÄúIlhas do Conhecimento: Compartilhando Pr√°ticas e Saberes entre Universidades e Comunidades da Periferia de Porto Alegre‚ÄĚ. O projeto Bacatelas existe h√° dois anos e vem desenvolvendo atividades socioeducativas com as comunidades e equipes das ESF Ilha da Pintada e Cruzeiro do Sul, incentivando por um lado, o cuidado com a sa√ļde ambiental atrav√©s do trabalho com a terra e por outro, a sa√ļde humana atrav√©s da troca de informa√ß√Ķes e utiliza√ß√£o das plantas dispon√≠veis nos hortos e na disponibiliza√ß√£o de um espa√ßo agrad√°vel e ornamental, acreditando-se com isso, alcan√ßar finalidade terap√™utica. O projeto, na busca de atingir tais objetivos, caracteriza-se por um interc√Ęmbio entre a sabedoria popular e o conhecimento propagado pela academia, seja na percep√ß√£o e intera√ß√£o com o meio, seja no trabalho de plantio e semeadura ou at√© no conhecimento das ervas, seu significado, nome ou fun√ß√£o. Essa busca √© desenvolvida atrav√©s de quatro eixos: (1) cria√ß√£o de oficinas, viv√™ncias e pr√°ticas vinculadas aos hortos; (2) disponibilidade √† popula√ß√£o dos bairros a utiliza√ß√£o de ervas e plantas em seu uso cotidiano, orientando e dialogando a respeito de seu uso medicinal, ornamental ou aliment√≠cio, ou mesmo a orienta√ß√£o e troca de conhecimento a respeito de seu plantio e cuidado; (3) integra√ß√£o e possibilidade √† comunidade, considerando seu contexto urbano metropolitano, do trabalho com a terra em todo o seu envolvimento, em diferentes formas de plantio, colheita e rega; (4) possibilidade de proporcionar um espa√ßo terap√™utico, bonito, saud√°vel e seguro, a ser de utiliza√ß√£o para todos que sintam necessidade de entrar nos hortos

    Elusive Anomalies in the Brazilian Stock Market

    We study the twist-of-the-Monday effect in the Brazilian stock market and provide evidence that it is due to index construction problems, such as the non-synchronous trading of stocks. The effect is present for indices but absent for most individual stocks and in the most recent sub-periods of the 1986-98 period. When present, it was due to negative weekend returns while Monday intraday returns were significantly positive. When absent, Monday returns remain positively correlated with the previous week return although Monday returns are no longer significantly negative. Monday trading strategies based on the previous week return were profitable in and out of the sample.Indisponível

    This work is based on a research about the principal‚Äôs perception about the management of municipal schools in Jacobina, Bahia, Brazil. The aim of this research was to analyze how principals perceive the pedagogical attributions that are required to develop the management of municipal schools in Jacobina. For this, we used as a data collection instrument a questionnaire whose application involved 22 principals who work in the city and rural schools. We adopted as a method a case study that uses, predominantly, ordinal variables, resulting from the application of Likert scale, and the result of the principals‚Äô perception was presented by degree of agreement/disagreement. The questionnaire contains proposals on the elaboration of the Political-Pedagogical Project (PPP), the School Development Plan (SDP), the participation of the principal in the pedagogical actions and the promotion of the participation of the different segments in the pedagogical actions. Based on the analysis of the data, we observed that most of the principals perceive that there are problems regarding the elaboration of the PPP and the SDP. They point out lack of time to participate in the pedagogical questions and, in relation to the participation of the several segments, indicate that there are difficulties in bringing the family to participate in the pedagogical actions, which does not happen in relation to teachers and pedagogical coordinators. We conclude that principals strive for pedagogical actions to occur in a participatory manner and realize the need to direct part of their work to follow the pedagogical attributions that are demanded of them when they take over the direction of the school.Este artigo decorre de uma pesquisa sobre a percep√ß√£o dos diretores acerca da gest√£o das escolas municipais de Jacobina (BA). A referida pesquisa teve como objetivo analisar como diretores percebem as atribui√ß√Ķes pedag√≥gicas que lhes s√£o demandadas para desenvolver a gest√£o das escolas municipais de Jacobina (BA). Para tal fim, utilizamos como instrumento de coleta de dados question√°rio cuja aplica√ß√£o envolveu 22 diretores que atuam nas escolas da sede e da zona rural. Adotamos como m√©todo um estudo de caso que faz uso de vari√°veis predominantemente ordinais, decorrentes da aplica√ß√£o de escala tipo Likert, e o resultado da percep√ß√£o dos diretores foi apresentado por grau de concord√Ęncia/discord√Ęncia. O question√°rio cont√©m proposi√ß√Ķes sobre a elabora√ß√£o do Projeto Pol√≠tico-Pedag√≥gico (PPP), do Plano de Desenvolvimento da Escola (PDE), da participa√ß√£o do diretor nas a√ß√Ķes pedag√≥gicas e da promo√ß√£o da participa√ß√£o dos diversos segmentos nas a√ß√Ķes pedag√≥gicas. Com base na an√°lise dos dados, observamos que a maioria dos diretores percebe que existem problemas em rela√ß√£o √† elabora√ß√£o do PPP e do PDE, apontam falta de tempo para participar das quest√Ķes pedag√≥gicas e, em rela√ß√£o √† participa√ß√£o dos diversos segmentos, indicam que existe dificuldades em trazer a fam√≠lia para participar das a√ß√Ķes pedag√≥gicas, o que n√£o acontece em rela√ß√£o aos professores e coordenadores pedag√≥gicos. Conclu√≠mos que os diretores se esfor√ßam para que as a√ß√Ķes pedag√≥gicas ocorram de forma participativa e percebem a necessidade de direcionar parte de seu trabalho para acompanhar as atribui√ß√Ķes pedag√≥gicas que lhes s√£o demandadas ao assumir a dire√ß√£o da escola

    Disserta√ß√£o (mestrado)‚ÄĒUniversidade de Bras√≠lia, Instituto de Artes, Programa de P√≥s-Gradua√ß√£o em Artes, 2018.O trabalho apresenta rela√ß√Ķes entre pot√™ncias dos movimentos oculares ‚Äď saberes e fazeres dos campos da psicologia, psicolingu√≠stica, oftalmologia e da Trataka (yoga) desenvolvidos em pr√°tica de pesquisa em artes c√™nicas ‚Äď e a quest√£o da presen√ßa c√™nica. A no√ß√£o de presen√ßa como atualidade em processo √© relacionada ao potencial de processamento dos movimentos dos olhos. A no√ß√£o de efeito de presen√ßa, como processo que alterna presen√ßa e aus√™ncia, √© relacionada a um di√°logo proprioceptivo que parece resultar de uma aten√ß√£o √† musculatura do olhar ‚Äď denominada extraocular ‚Äď em rela√ß√£o ao investimento expressivo em outras regi√Ķes do corpo em cena. Essa aten√ß√£o define um princ√≠pio de foco na musculatura extraocular como modo de favorecer o processo de presen√ßa c√™nica. Na perspectiva desse princ√≠pio, o trabalho relata seis a√ß√Ķes art√≠sticas que constituem o corpo da pr√°tica de pesquisa. Tra√ßa rela√ß√Ķes entre os modos de explora√ß√£o que emergiram nesse per√≠odo e o princ√≠pio de foco na musculatura extraocular para a pr√°tica atorial, explicitando o papel de cada momento no percurso de pesquisa, que conduziu √† organiza√ß√£o desse princ√≠pio. Pretende-se reconhecer, tamb√©m, como, no curso de cada a√ß√£o art√≠stica, esses modos de explora√ß√£o afetaram outras dimens√Ķes da pesquisa e da cria√ß√£o c√™nica, como a da est√©tica e da √©tica.This work presents relationships between the potential of ocular movements ‚Äď knowledge and practices arising from the fields of psychology, psycholinguistics, ophthalmology and Trataka (yoga) and developed in performing arts‚Äô research practice ‚Äď and the matter of scenic presence. The notion of presence as presentness is related to the processing potential of eye movements. The notion of presence effect, as a process that alternates between presence and absence, is related to a proprioceptive dialogue that seems to result from na attention to the musculature of the eye ‚Äď called extraocular muscles ‚Äď in relation to the investment on other regions of the body while on the scene. This attention defines a principle of focus on the extraocular musculature as a way to favor the process of scenic presence. From the perspective of this principle, the work reports six artistic actions that constitute the corpus of this research practice period. It traces relations between the modes of exploration that emerged during this period and the principle of focusing on the extraocular musculature for atorial practice, explaining the role of each moment in the course of the practical research that led to the organization of such principle. It is also intended to recognize how, in the course of each artistic action, these modes of exploration affected other dimensions of research and scenic creation, such as the dimensions of aesthetics and of ethics

    Does this dog hunt? Testing the performance of the dogs of the dow strategy in the U.S. and in Brazil

    Get PDF
    This study analyzes the performance of the Dogs of the Dow Jones (DoD) investment strategy in the U.S and in Brazil on an absolute and on a risk adjusted basis. The DoD is a value oriented strategy that calls for investing equal dollar amounts in the highest yielding components of the Dow Jones. Our performance evaluation findings demonstrate that the DoD strategy shows only limited evidence that it can add value as an investment strategy in the U.S stock market. The use of the DoD strategy in Brazil shows virtually no evidence that it can add value as an investment strategy. Our analysis suggests that the dividend yield may not be a good variable to select value stocks in the U.S and in Brazil given existing empirical evidence that value stocks have outperformed growth stocks in these markets.Indisponível

    This paper uses an ARCH framework to study stock market linkages in Latin American markets. We provide evidence that most markets exhibit ARCH effects even when multivariate information sets are incorporated. The correlations between Latin America with the US and developed markets have increased over time for all countries except Argentina. The linkages across Latin American countries also have strengthened. We also find that the volatility transmission between the US and Latin America has increased more recently. In contrast, the volatility transmission among Latin American countries has decreased. Overall our results reveal that Latin American financial markets are becoming more globalized and integrated not only with other countries in the region but also with developed markets.Este artigo emprega o m√©todo ARCH para estudar os elos dos mercados de a√ß√Ķes da Am√©rica Latina. N√≥s oferecemos evid√™ncia de que a maioria dos mercados apresentam efeitos ARCH mesmo quando conjuntos de informa√ß√£o multivariados s√£o incorporados. As correla√ß√Ķes entre a Am√©rica Latina e os EUA e os mercados desenvolvidos aumentaram com o tempo para todos os pa√≠ses, menos a Argentina. Os elos entre os mercados latinos tamb√©m se fortaleceram. N√≥s tamb√©m encontramos evid√™ncia de que a transmiss√£o de volatilidade entre a Am√©rica Latina e os EUA aumentou recentemente. Por outro lado, a transmiss√£o de volatilidade entre os mercados latinos diminuiu. De forma geral, nossos resultados revelam que os mercados da Am√©rica Latina est√£o mais globalizados e integrados, n√£o somente com os outros pa√≠ses da regi√£o, mas tamb√©m com os mercados desenvolvidos

    Corporate governance, market valuation and dividend policy in Brazil

    Get PDF
    This study investigates the effects of the corporate governance structure on market valuation and dividend payout of Brazilian companies. The empirical results indicate a high degree of ownership and control concentration. We can also note a significant difference between the voting and total capital owned by the largest shareholders, mainly through the existence of non-voting shares, pyramidal structures, and shareholding agreements. These mechanisms seem to be used by controlling shareholders to keep the firm’s control without having to own 50% of the total capital. The evidence also reveals that there is a relationship between governance structure, market valuation, and dividend policy in Brazil.Indisponível

    Evaluation of the 238^{238}U Neutron Cross Section in the Unresolved Resonance Range

    Get PDF
    International audienceThis paper presents a new analysis of the 238^{238}U cross sections in the unresolved resonance range, from 20 keV to 150 keV.Statistical analysis of the resonance parameters in the resolved resonance rangewith random-matrix theory provides accurate experimental values of strength function and average level spacing for s- and p-waveresonances. Above 20 keV, the simultaneous fit of selected experimental data (average transmission and capture) is performed with a statistical model of nuclear reactionas implemented in the SAMMY code.Compared to previous evaluations, such as those described by Fröhner or by Maslov et al., this work benefits from the accurate transmission data measured by Harvey et al. at Oak Ridge Electron Linear Accelerator, which have never been studied before. This new evaluation was written into the current ENDF format for use in practical applications. This work stresses the need for an improved ENDF format to store average resonance parameters and cross sections in the unresolved resonance range

    [Resumo] Os res√≠duos s√≥lidos s√£o considerados grandes desafios de gest√£o associados ao crescimento populacional e crescimento de consumo. Em 2010 foi institu√≠da no Brasil a lei 12305 que trata da Pol√≠tica Nacional de Res√≠duos S√≥lidos, trazendo consigo uma s√©rie de desafios a serem superados em prol da sua melhor gest√£o e da qualidade ambiental. Por√©m, a implementa√ß√£o da pol√≠tica tem sido dif√≠cil, e evidenciado lacunas e problemas. Um desses problemas versa sobre a coleta seletiva que buscamos avaliar no munic√≠pio de Rio das Ostras considerando dois segmentos da sociedade: o poder p√ļblico e a sociedade civil. O trabalho buscou compreender a vis√£o destes acerca de pol√≠ticas p√ļblicas para a gest√£o de res√≠duos s√≥lidos. Inicialmente realizou-se levantamento bibliogr√°fico sobre o tema, bem como levantamento e an√°lise de documentos municipais, seguidos de 2 entrevistas com gestores. Realizaram-se 79 entrevistas com mun√≠cipes em logradouros e 23 em pontos de entrega volunt√°ria utilizando question√°rios semi-estruturados. O munic√≠pio apresenta muitas dificuldades na gest√£o e no cumprimento da lei. A popula√ß√£o mostrou conhecimento acerca da pol√≠tica no que concerne √† coleta seletiva, alguns mostrando desinteresse e descr√©dito e outros participando de forma direta do que h√° implementado pelo munic√≠pio e de forma indireta pela doa√ß√£o a catadores.[Abstract] Solid waste is considered major management challenges associated with population growth and consumption growth. In 2010 it was instituted in Brazil to 12305 law that deals with the National Solid Waste Policy, bringing with it a series of challenges to be overcome for the sake of better management and environmental quality. However, policy implementation has been difficult, and highlighted gaps and problems. One such versa problems on the selective collection we seek to evaluate the municipality of Rio das Ostras considering two segments of society: the government and civil society. The stydy sought to understand the vision of these about public policies for the management of solid waste. Initially held literature on the subject, as well survey and analysis of municipal documents, followed by two interviews with managers. There were 79 interviews with residents in public parks and 23 voluntary delivery points using semi-structured questionnaires. The city presents many difficulties in management and law enforcement. The population showed knowledge of policy regarding the selective collection, some showing disinterest and distrust and other participating directly of what is implemented by the municipality and indirectly by donation to collector
