PROAGRO - Programa de Garantia de Atividade Agropecuaria: avaliação de seus objetivos na microrregião homogenea de Passo-Fundo - RS

No Brasil nao e raro a criação de Programas pelas autoridades governamentais, para atender. determina da situação conjuntural ou para direcionar os esforços de pro . .' dução a uma atividade específica. Ocorre, porém, na maioria das vezes que não se criam -- simultaneamente ã formulação-instr~ mentos efetivos para sua avaliação e assim, os programas se agigantam e -introdu~em seus próprios mecanismos de de fesa para sua autopreservação. Este trabalho objetiva avaliar um deles --- o PROAGRO - Programa de Garantia da Atividade Agropecuá - ria --- através de uma confrontação entre a visão de seus for muladores e,a dos diversos agentes que atuam na operaciona lização do programa, em uma microrregião homogênea do LB.G. E., constituída pelos segu~ntes municípios: Carazinho, Chap! da, Coronel Bicaco, Palmeira das Missões, Passo Fundo e Santo Augusto, todos situados no Estado do Rio Grande do Sul. Com ênfase nos aspectos de formulação de políticas públicas, este trabalho foi desenvolvido dentro de uma sistemática, cuj as idé"'ias básicas discriminamos a seguir: descrição da importância do PROAGRO e, em virtude dele estar intimamente vinculado ao Sistema Nacional de Crédito Rural, dos objetivos, do desempenho e das disfunções desse Sistema. Como corolário, constata-se que pou cos agricultores têm acesso ao crédito rural institucio na1izado e entre seus beneficiários há uma concentração excessiva dos recursos; - registros dos antecedentes da implantação do seguro agrícola no Brasil, inclusive a experiência frustrada da Companhia Nacional de Seguro Agrícola (1954-1966); - análise do conteúdo formal da política e do desempenho em termos financeiros. ao longo dos se'is primeiros anos de atuação. Em decorrência emerge o fato' de que o programa vem sofrendo constantes déficits e há uma concentração excessiva na utilização de recursos por um tipo de cultura· (trigo) em uma determinada região (Sul); divulgação do resultado da pesquisa-junto aos vários a gentes que atuam no programa e dentre outras conclusões, ·1. constatam-se~indfcios de que o objetivo de auxílio na utilização de tecnologia moderna -- apregoada pelas suas normas -- nãR vem sendo atingido, oco~rendo, em alguns casos, o inverso, ou seja, a acomodação dos agricultores; - descrição dos modelos de seguro agrícola de três ses, Estados Unidos, México e Japão, para fornecer sub sídios ã análise do programa. t marcante a preocupa - ção do governo desses países em manter o programa dentro de critérios exclusivamente técnicos, lastreados em cálculos atuariais para definição dos percentuais de prêmios a serem cobrados; - comparação entre as duas visões descritas e as suges - tões dos modelos de outros países citados. Conclui-se pela necessidade de assegurar ao programa um maior rigor técnico na condução das operações de seguro e com ênfase apenas na forma de administração, propõe-se duas altern~tivas para consolidação do seguro agrícola no Brasil, a saber: 1) o aperfeiçoamento do programa; 2) a transferência gradativa para esfera do Sistema de Seguro Rural, com a vigilância e aporte financeiro do Governo Federal.

Quebrando as regras: o poder discricionário na linha de frente do programa esportivo-social RIO 2016 um estudo sobre a situação do integrador de núcleo, um verdadeiro "sociological citizen"

Este estudo analisa o indivíduo que atua na linha de frente do RIO 2016, um programa social do Governo do Estado do Rio de Janeiro que opera 800 unidades de atendimento no Estado, com gestão da Secretaria de Estado de Esporte e Lazer. O indivíduo analisado nesta pesquisa é denominado Integrador de Núcleo Esportivo e é o responsável pela gestão de uma dessas unidades — Núcleo Esportivo — que atende em média 50 alunos de uma comunidade carente no Estado do Rio de Janeiro. Essa pesquisa analisa o Integrador de Núcleo Esportivo sob uma perspectiva inédita, entendendo-o como um agente que atua além do seu escopo burocrático de trabalho. Para esse estudo foram consideradas teorias sobre burocracia organizacional, lançando mão da literatura de Michel Crozier ―The Bureaucratic Phenomenon‖ (1964), que analisa as relações entre pessoas, grupos e poder para entender a influência da organização burocrática no indivíduo. O termo ―sociological citizen‖,desenvolvido por Silbey (2009), também foi considerado para classificar esse indivíduo que se mostra mais aplicado que outros nos serviço de seu mandato organizacional e legal. Silbey aplica também o termo ―relational regulation‖ para denominar esta forma particular de prática da ―cidadania sociológica‖ (tradução do autor), por meio da qual os agentes ―governam a lacuna existente entre as expectativas regulatórias e o desempenho requerido‖.

O programa de integração e formação como meio de inclusão social e inovação pedagógica: um olhar etnográfico

Esta investigação inserida no mestrado em Ciências da Educação- Inovação Pedagógica tem como objetivo conhecer a cultura escolar, designadamente, as práticas pedagógicas no âmbito do programa, Plano Integrado de Educação e Formação (PIEF), num estabelecimento de ensino do Funchal. A procura de uma eventual mudança de paradigma, assim como, de inovação pedagógica, poderá comprovar e reforçar a necessidade de alterar os trilhos que levam a Escola atual a afastar-se do lugar-comum. Nesta perspetiva, o rumo a seguir passará pela Mudança, podendo o foco da mesma estar numa pequena comunidade (cultura) ou num programa, cujo estudo particular permitirá conhecer como atuam os seus agentes de aprendizagem. O desafio central da investigação emana da seguinte questão: Será o PIEF um meio de inclusão e, em simultâneo, de inovação pedagógica? Com vista a evidenciar a pertinência desta questão, foram desenvolvidos conceitos temas e abordadas teorias de aprendizagem contemporâneas que ao se concretizarem como suporte teórico de fundamentação, contextualizam o estudo e constituem a base de orientação para o trabalho de investigação no campo. A metodologia de investigação privilegiada apresenta um carácter etnográfico, uma vez que particulariza o conhecimento dos fenómenos sociais, a microanálise e a visão holística sobre a comunidade local. A definição do seu foco associado a um programa e a sua delimitação no tempo e no espaço classifica-o de estudo de caso etnográfico. O objetivo final será compreender e analisar a cultura da Escola Vila Mar através da observação participante e das narrativas dos seus intervenientes, de modo a aferir da veracidade ou logro da questão basilar. A necessidade de implementação do programa PIEF nesta escola foi a resposta encontrada face à inadequação do currículo nacional, no entanto, não se verificou no seu estudo o ímpeto suficiente para criar a metamorfose necessária.

Efeitos biológicos in vitro de agentes físicos utilizados em fisioterapia

The uses of radiobiocomplexes labeled with technetium-99m contributed to health science advances. Stannous chloride (SnCl2) has been used as a reducing agent for the labeling process. Cytotoxic and genotoxic effect of the SnCl2 have been described in several studies and with this experimental models alterations in molecular and cellular level can be evaluated. In the last years the physicals therapists acquired new devices which emits electromagnetic radiation such us Extremely Low Frequency Pulsated Electromagnetic Fields (E.L.F. P.E.M.F.), radiofrequency, Intense Pulsed Light (I.P.L.) and others which emits sonic waves such us Biorresonance. Scientific evidence of the effects and dosage is important to protect public health and to reach exposition levels that result in significant biological effects. The aim of this project is to verify the effects of these physical agents in plasmid DNA and E. coli AB1157 cultures in presence or absence of SnCl2 and the effects in blood constituents labeled with technetium-99m. Wistar rats blood was exposed to the cited sources and the labelling of blood constituents with 99mTc was carried through. Cultures of E. coli AB1157 and plasmidial samples DNA had been also exposed the physical agents. The results suggest that these agents are capable of altering neither the survival of E. coli cells or plasmid DNA electrophoresis mobility. The multidiscipline character was clearly in this study due the interaction between Nuclear Medicine department of the UERJ and the Laboratory of Physical Agents of the Maimonides University in Argentina until the union between the teacher (biomedical and physiotherapist) and student (physiotherapist), besides collaborators of the area of Physics and Biology, promoting new ideas and perspectives and also adding the knowledge of different areas and origins

Análise da presença de agentes mutagênicos nas águas do Rio Pitimbú/RN

The Pitimbu River is located at the oriental portion of the State of Rio Grande do Norte, including three importants cities named Macaíba, Parnamirim e Natal. Although its high importance as a water source, which supplys great part of the South Zone of the Natal city, this river receives a large quantity of domestic and industrial waste water without treatment. The Pitimbu River headhas its river-head located in the city of Macaiba, goes through Parnamirim, then it flowing into at the Jiqui Lake in Natal. The aim of this study was to evaluate, qualitatively and quantitatively, the environmental quality of the Pitimbu River by genotoxicity bio-assays, which are important tools for genetics toxicological evaluation. In this work, five samples sites, distributed along the river, were used to collect water samples. Another point site, located near Jiqui lake, was used to collect drinkable water, which was treated by CAERN, the water treatment entreprise of Rio Grande do Norte. The following assays where used to evaluate the quality of these samples: Allium cepa assay; Comet assay; Micronuclei (MN) assay; and Ames test. For the Allium cepa assay, sixteen specimes where used for each water sample from the sample sites. In this assay both microscopic, like cytogenetic damage, and macroscopic aspects, as morphological variation were evaluated. Red blood cells from periferical blood of the Crenicichla menezesi native specie were used not only for the MN assay, but also for the Comet assay. These fishes were collected at different points on the Pitimbu River and the negative control was developed using fishes of the same species that were bring to the laboratory and maintained for 100 days in the optimal experimental conditions. For the Ames test, TA100, YG1042, TA98 and YG1041 strains were used in the directed method without metabolic activation. The results found by the Allium cepa assay showed that two water sample sites induced increase of mitotic index (IM). Additionally, compared to the control, all the water samples increased the chromossomal aberrations frequency and/or micronucleus. Among the sample sites, two also showed an abnormal growth rate in its root and two samples induced morphological alteration. With the MN test in red blood cells, a high frequence of MN was observed in tree sample. By comparing all the results obtained on the water sample points and with the negative control, a significant variation on the MN frequency was observed. Positive results were also observed for the same sample to water test by the Comet assay. These results allow concluding that the proposed specie Crenicichla menezesi has a good profile as a bio-indicator for the evaluation of environmental water quality and the MN and comet test can be usuful for in situ evaluation. By the Ames test, it was possible to detect the mutagenic activity on the waters from the Pitimbu River in different levels of mutagenicity. This result suggests that this river has several substances that induced changes directly to the DNA. The mechanisms involved to this phenomenon could be by both processes, by changing of the reading frame and by nucleotide substitution. These data set indicate the presence of mutagenic agents, which can represent in risk to biot and human beens

Programa alfabetização solidária: um estudo sobre a experiência no município de Lagoa de Pedras/RN (1997 - 2003)

The educational reform of the 90 s was tainted by the objectives of the fiscal adjustments, resulting in the redefinition of the state s role in the financing and offering of teaching services, and bringing about a shuffling of the responsibility between the public and private sectors to promote education to young people and adults. The 90 s also highlighted the proliferation of providers and the multiplication of Educational Programs for Youths and Adults (EJA), implemented through partnerships between governmental and nongovernmental agencies. During this period of time, the agenda of educational responsibilities concerning analphabetism was organized in a process of decentralized of the state, with the following political, social, and economic objectives: to reduce the public deficit, increasing public savings and the financial capacity of the state to concentrate resources in areas considered indispensable to direct intervention; to increase the efficiency of the social services moffered or funded by the state, giving citizens more at a lower cost, and spreading services to more remote areas, expanding access to reach those most in need; to increase the participation of citizens in public management, stimulating communitarian acts as well as developing efforts towards the effective coordination of public figures in the implementation of associated social services. Thus, Assistance Programs co-financed by the government try to deal with the problem of analphabetism. Within the sphere of the 90 s educational policy decentralization, we come to see how the agenda dedicated to the reduction of analphabetism was formed by the Solidarity Alphabetization Program (PAS). Between 1997 and 2003, the latter agenda s decentralizing proposal was integrated in the management partnership for the operationalization of tasks and resources faced with the execution of the formal objectives. In this study, we identify the dimensions of the implantation and progress of the tasks carried out by PAS, in the municipality of Lagoa de Pedras/RN. However, we consider these Programs to assist in the process without guaranteeing the reduction of the causes or substituting the responsibility of the system once the monetary resources for program maintenance provided by the partners is exhausted

Campo educacional e representação social da formação docente :o olhar dos agentes

Teaching formation has been the target of many changes, having been forged according to numerous formats and models through different times and spaces, composing thus, different codes and curricular proposals for different levels of qualification. We've tried in this work to pinpoint the main discussions which take place in the area of the teaching formation, based in the views of modern writers. We ve also tried, through the Social Representations Theory, to reveal and learn how the agents directly involved in this process realize and react, that is, the teachers who cope with the beginning stages of the Fundamental Teaching in the public school system in Natal/RN, taking into account that, in many cases, such formation demands the rethinking of the very formation policies. We've also adopted the concepts of field and educational field introduced by the praxiology of Pierre Bourdieu. It s been considered a fundamental theoretical reference which enables the understanding of social phenomena, both in macro and micro viewpoints. Thus, we do not neglect the whole, and particularly, the nuances of each context or specific situation. In the methodological track we ve used for data gathering the Free Word Association Test, and the Semi-Structured Interview, and also secondary sources for the characterization of the research spectre. Data treatment and analysis were performed with the help of the following software: SPSS Statistical Package for Social Sciences and EVOC; and the method of Content Category Analysis. The combination of the concepts and techniques mentioned above was necessary to cope with the qualitative and quantitative aspects, in our attempt to offer a wider range of contributions and outcome validations, which have shown, among other less explicit elements, the existence of a social representation of the teaching formation such as: knowledge theoretical and practical; a necessity imposed by the symbolical conflicts of the social field; capacitation and compromisse. We acknowledge the relevance of the thoughts discussed here, though aware that this is just one of the possible approaches to the theme

Efeitos de um programa de intervenção precoce baseado no modelo mais que palavras - HANEN, para crianças menores de três anos com risco de autismo

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response

Uma arquitetura baseada em agentes para configuração dinâmica de aplicações inteligentes em ambiente foundation fieldbus

The industrial automation is directly linked to the development of information tecnology. Better hardware solutions, as well as improvements in software development methodologies make possible the rapid growth of the productive process control. In this thesis, we propose an architecture that will allow the joining of two technologies in hardware (industrial network) and software field (multiagent systems). The objective of this proposal is to join those technologies in a multiagent architecture to allow control strategies implementations in to field devices. With this, we intend develop an agents architecture to detect and solve problems which may occur in the industrial network environment. Our work ally machine learning with industrial context, become proposed multiagent architecture adaptable to unfamiliar or unexpected production environment. We used neural networks and presented an allocation strategies of these networks in industrial network field devices. With this we intend to improve decision support at plant level and allow operations human intervention independent

Agentes Inteligentes com Foco de Atenção Afetivo em Simulações Baseadas em Agentes

Simulations based on cognitively rich agents can become a very intensive computing task, especially when the simulated environment represents a complex system. This situation becomes worse when time constraints are present. This kind of simulations would benefit from a mechanism that improves the way agents perceive and react to changes in these types of environments. In other worlds, an approach to improve the efficiency (performance and accuracy) in the decision process of autonomous agents in a simulation would be useful. In complex environments, and full of variables, it is possible that not every information available to the agent is necessary for its decision-making process, depending indeed, on the task being performed. Then, the agent would need to filter the coming perceptions in the same as we do with our attentions focus. By using a focus of attention, only the information that really matters to the agent running context are perceived (cognitively processed), which can improve the decision making process. The architecture proposed herein presents a structure for cognitive agents divided into two parts: 1) the main part contains the reasoning / planning process, knowledge and affective state of the agent, and 2) a set of behaviors that are triggered by planning in order to achieve the agent s goals. Each of these behaviors has a runtime dynamically adjustable focus of attention, adjusted according to the variation of the agent s affective state. The focus of each behavior is divided into a qualitative focus, which is responsible for the quality of the perceived data, and a quantitative focus, which is responsible for the quantity of the perceived data. Thus, the behavior will be able to filter the information sent by the agent sensors, and build a list of perceived elements containing only the information necessary to the agent, according to the context of the behavior that is currently running. Based on the human attention focus, the agent is also dotted of a affective state. The agent s affective state is based on theories of human emotion, mood and personality. This model serves as a basis for the mechanism of continuous adjustment of the agent s attention focus, both the qualitative and the quantative focus. With this mechanism, the agent can adjust its focus of attention during the execution of the behavior, in order to become more efficient in the face of environmental changes. The proposed architecture can be used in a very flexibly way. The focus of attention can work in a fixed way (neither the qualitative focus nor the quantitaive focus one changes), as well as using different combinations for the qualitative and quantitative foci variation. The architecture was built on a platform for BDI agents, but its design allows it to be used in any other type of agents, since the implementation is made only in the perception level layer of the agent. In order to evaluate the contribution proposed in this work, an extensive series of experiments were conducted on an agent-based simulation over a fire-growing scenario. In the simulations, the agents using the architecture proposed in this work are compared with similar agents (with the same reasoning model), but able to process all the information sent by the environment. Intuitively, it is expected that the omniscient agent would be more efficient, since they can handle all the possible option before taking a decision. However, the experiments showed that attention-focus based agents can be as efficient as the omniscient ones, with the advantage of being able to solve the same problems in a significantly reduced time. Thus, the experiments indicate the efficiency of the proposed architecture

Utilização de microemulsões como agentes modificadores de superfícies para remoção de íons metálicos

The heavy metals are used in many industrial processes and when discharged to the environment can cause harmful effects to human, plants and animals. The adsorption technology has been used as an effective methodology to remove metallic ions. The search for new adsorbents motivated the development of this research, accomplished with the purpose of removing Cr (III) from aqueous solutions. Diatomite, chitosan, Filtrol 24TM and active carbon were used as adsorbents. To modify the adsorbent surface was used a bicontinuous microemulsion composed by water (25%), kerosene (25%), saponified coconut oil (10%) and as co-surfactant isoamyl or butyl alcohols (40%). With the objective of developing the best operational conditions the research started with the surfactant synthesis and after that the pseudo-ternary diagrams were plotted. It was decided to use the system composed with isoamyl alcohol as co-surfactant due its smallest solubility in water. The methodology to impregnate the microemulsion on the adsorbents was developed and to prepare each sample was used 10 g of adsorbent and 20 mL of microemulsion. The effect of drying time and temperature was evaluated and the best results were obtained with T = 65 ºC and t = 48 h. After evaluating the efficiency of the tested adsorbents it was decided to use chitosan and diatomite. The influence of the agitation speed, granule size, heavy metal synthetic solution concentration, pH, contact time between adsorbent and metal solution, presence or not of NaCl and others metallic ions in the solution (copper and nickel) were evaluated. The adsorption isotherms were obtained and Freundlich and Langmuir models were tested. The last one correlated better the data. With the purpose to evaluate if using a surfactant solution would supply similar results, the adsorbent surface was modified with this solution. It was verified that the adsorbent impregnated with a microemulsion was more effective than the one with a surfactant solution, showing that the organic phase (kerosene) was important in the heavy metal removal process. It was studied the desorption process and verified that the concentrated minerals acids removed the chromium from the adsorbent surface better than others tested solutions. The treatment showed to be effective, being obtained an increase of approximately 10% in the chitosan s adsorption capacity (132 mg of Cr3+ / g adsorbent), that was already quite efficient, and for diatomite, that was not capable to remove the metal without the microemulsion treatment, it was obtained a capacity of 10 mg of Cr3+ / g adsorbent, checking the applied treatment effectiveness

Capacitação no Programa de Saúde da Família: divergências sobre o conceito de visita domiciliar nas equipes de Presidente Epitácio, São Paulo

O Programa de Saúde da Família (PSF) tem por intenção - e mérito - mudar o foco da atenção à saúde centrada no médico e na cura das doenças, para uma atenção centrada na promoção da saúde e prevenção de doenças por meio de uma equipe multidisciplinar. Para atingir esse objetivo, tem na prática de trabalho da visita domiciliar um dos instrumentos fundamentais para o entendimento da totalidade dos condicionantes que afetam a vida do cidadão. Neste artigo, discutem-se os conceitos de visita domiciliar com que operam as três principais categorias de trabalhadores do PSF - médicos, enfermeiros e agentes comunitários - , assim como sua relação com a formação no curso básico. A metodologia se baseia na técnica do discurso do sujeito coletivo a partir das entrevistas aplicadas. Concluímos que a falta de uniformidade sobre o conceito de visita domiciliar pode interferir na proposta de mudança do modelo de atenção à saúde. O artigo tece ainda considerações sobre as distintas concepções de visita domiciliar e sua relação com a organização do trabalho no interior das equipes.
