A planificação táctica em andebol: os momentos determinantes, as estratégias de intervenção no jogo e a comunicação do treinador na condução da equipa durante a competição

O presente estudo pretendeu averiguar a intervenção do treinador de andebol na Condução de uma equipa em Competição. Neste sentido, desenvolvemos o conceito de Planificação Táctica que em sentido lato refere-se à aplicação prática dos meios ao dispor do treinador, de acordo com um conceito de jogo próprio e com uma estratégia previamente definida, com o objectivo de ganhar um determinado confronto competitivo. Os objectivos deste estudo consistem em primeiro lugar, conhecer em profundidade o jogo de andebol, questionando os peritos da modalidade sobre três aspectos: que momentos determinantes existem no jogo de andebol, qual a sua ordem de importância e que estratégias de intervenção eles utilizariam nesses momentos; em segundo lugar pretendemos caracterizar a intervenção em competição dos treinadores de andebol quanto à forma de comunicação verbal. Os métodos de pesquisa utilizados foram o questionário (para conhecer o jogo de andebol) e um sistema de observação em vídeo (para caracterizar a comunicação do treinador em competição). Foram analisados dezasseis treinadores de alto nível por questionário e cinco por observação vídeo. Os questionários foram aplicados e as filmagens dos jogos efectuadas durante a época de 1999/2000. Da pesquisa efectuada por questionário decorrem as principais conclusões: 1) existem momentos em que a intervenção do treinador é determinante para o resultado final do mesmo. Durante o jogo é determinante o treinador intervir: 2) nos momentos finais do jogo em igualdade e desvantagem no marcador e quando a equipa sofre uma exclusão temporária; 3) de acordo com o cumprimento ou o resultado prático do plano táctico estabelecido; 4) fazendo substituições por lesão, por incumprimento das missões tácticas, como resposta às condições específicas do jogo e de acordo com funções defensivas e/ou ofensivas; 5) gerindo os descontos de tempo, solicitando-os de acordo com as exigências do jogo e intervindo ao nível colectivo e individual; 6)relacionando-se com os árbitros, mantendo sempre a cordialidade independentemente do resultado do jogo. Durante o Intervalo do jogo é determinante o treinador: 7) reunir rapidamente com o adjunto e dirigir a sua intervenção para as acções colectivas da equipa. Das estratégias que os treinadores afirmaram utilizar salientam-se as seguintes: Durante o jogo os treinadores afirmam intervir: 8) sobre o colectivo da equipa, reservando uma intervenção individualizada para os momentos de exclusão de jogadores; 9) nos descontos de tempo tanto colectiva como individualmente; Durante o intervalo do jogo os peritos afirmam: 10) iniciá-lo com uma análise colectiva da equipa. Da pesquisa efectuada por observação vídeo decorrem as principais conclusões: 11) a comunicação verbal dos peritos observados caracteriza-se por mensagens gerais, dirigidas para o colectivo ou para um jogador de campo, de carácter maioritariamente pressionante e aprovativa (quando os treinadores ganham os jogos) e de natureza defensiva.

Dificuldades de aprendizagem específicas: estudo de caso sobre dislexia

Neste estudo abordamos aspectos relacionados com as dificuldades de aprendizagem específicas designadamente a dislexia, debruçando-nos sobre a questão conceptual, sua tipificação, etiologia e processos de avaliação e intervenção. A dislexia é uma dificuldade da aprendizagem da leitura que não se pode explicar por um défice cognitivo nem sensorial, nem por um ambiente social ou familiar desfavorável, nem por métodos de ensino desajustados. O estudo empírico que desenvolvemos, consiste na caracterização de um grupo de alunos com o diagnóstico de dislexia bem como no levantamento dos procedimentos mais usuais em termos de avaliação e reabilitação. A recolha de dados foi realizada num Centro de Apoio Psicopedagógico da Madeira, através da consulta de documentos constantes dos processos dos alunos diagnosticados com dislexia/disortografia e inscritos na educação especial e da realização de entrevistas a psicólogas do mesmo centro. A amostra é constituída por 52 alunos distribuídos pelos vários ciclos escolares do ensino básico e do ensino secundário a frequentarem 15 escolas do concelho adstritas ao CAP. Para a organização da informação recolhida através da análise documental, utilizámos uma grelha de registo e na condução das entrevistas utilizámos um guião que contempla, genéricamente, questões relacionadas com a etiologia, despiste e reabilitação da dislexia. Os resultados do estudo, apontam para um maior número de rapazes com diagnóstico de dislexia do que raparigas, diagnósticos um pouco tardios, sobretudo nos grupos de alunos mais velhos, alguma heterogeneidade na utilização de instrumentos de avaliação nos diferentes casos e alguma dificuldade em estruturar medidas educativas específicas e direccionadas a esta problemática. Neste sentido, tecemos algumas considerações face à necessidade de um diagóstico atempado, uma maior sensibilização e, formação dos vários técnicos envolvidos no diagnóstico e na intervenção, bem como, propomos sugestões para o desenvolvimento de estudos posteriores que permitam o aprofundamento e um maior conhecimento sobre esta problemática.

Novos contextos de aprendizagem : processos de letramento a partir dos gêneros digitais

Num mundo em constante transformação e cercado de novas tecnologias, é necessário que os estudantes desenvolvam habilidades que vão além do letramento alfabético, é urgente ser digitalmente letrado. No entanto, contrariando as mudanças aceleradas que acontecem na sociedade, a escola contemporânea insiste na manutenção do paradigma educacional adotado desde a Revolução Industrial, ancorado no modelo instrucionista da educação de massas. Considerando que o pleno domínio da língua é algo essencial para nos tornarmos cidadãos ativos, este estudo pretende investigar processos de letramento a partir dos gêneros textuais que circulam na sociedade, dando relevo aos gêneros digitais e suas contribuições ao desenvolvimento linguístico-cognitivo do educando. Como o desenvolvimento das habilidades de leitura e escrita ainda é um problema nas escolas, e sendo os gêneros digitais pouco explorados nas aulas de língua materna, temos por objetivo analisar como práticas pedagógicas voltadas para a produção de gêneros textuais digitais e não digitais, nas aulas de Língua Portuguesa, contribuem para a formação de leitores e escritores proficientes no Ensino Fundamental. A pesquisa realizada foi de natureza etnográfica, pesquisa-ação, e aconteceu em uma turma do 8º ano de uma escola pública do município de Recife – PE/Brasil. Para coleta de dados utilizei a observação participante completa, a entrevista etnográfica semiestruturada e a análise documental. Os resultados obtidos apontam que os contextos criados para que os alunos se tornem cidadãos letrados facilitaram o debate e a interação, estimularam a autonomia e a aprendizagem colaborativa e promoveram a construção do conhecimento, sendo, mesmo que a nível micro, Inovação Pedagógica.

A representação social do papel de gestores em organizações não governamentais

The discussions concerning the absence of a management model appropriate to the peculiarities of third sector organizations have not been impeditive to their emphasized expansion in the last decades. In the attempt of understanding this phenomenon from the perspective of those who manage social organizations, this work based on the theory of social representations to understand the notion that organization managers of the third sector - based in Fortaleza CE - have of the part that they play and how this notion influences the direction of their activities. Social representations of managers of four different categories of non-governmental organizations have been investigated, each category composed of two unities. The categories researched were: social integration through art and education, prevention and treatment of alcohol and drug abuse, children s health assistance and community action. By using Doise s Societal Approach, the role of social managers translated in intraindividual, interindividual and situational processes of their actions, has been analysed within the social representations, focusing on beliefs, values, symbols and stories that give meaning to the existence of non-governmental organizations. Analysis and discussion of data displayed the existence of diversity in the understanding of managers within their practice, in other words, the management profile is also its own manager s. The branch where an organization acts is also preponderant in the shaping of a management style. It could be deduced, from to the organizations researched, that professional formation and the manager s social insertion mainly, are determinative factors in the outlining of a management model of its own. It was concluded that, due to heterogeneity of interests and action segments, there is no systematic process for social management among organizations. Management styles are supported by their director s own perception of achievement, who model organizations according to their contingencies

Coevolução e as práticas isomórficas de gestão: um estudo sobre os processos de mudanças institucionais no Instituto Federal de Educação, Ciência e Tecnologia do RN

The Federal Institution for Education, Science and Technology, in its historical path, has been living different changes. The transformations occurred along the way have been determined by coercive forces from the institutional environment, which has became more and more broad and complex throughout the time, obtaining diverse characteristics and new elements such as non institutional factors1 which started to contribute with the other changes. In this context, this work aims to study the isomorphic practices of the managers in the institutional changes process of the IFRN in 1998 and 2008, as of a theoretical coevolutionary perspective (CHILD; RODRIGUES; LEWIN; CARROL; VOLBERDA, 2003). This theory brings a new point of view for the organization analysis to the organizational studies, since it offers a non deterministic and non linear lection of the evolution process, which means, a coevolution. Thus, the organizations and their institutional and non institutional environment auto evolve, auto organize and auto reproduce. Therefore, the institutional and non institutional factors of the macro environment keep a continuous interdependence relationship with the organizations. For the means of this study, it is important to understand that is impossible to comprehend the object, the isomorphic practices, without considering that the previous institutional changes and its evolutions, its continuations and discontinuations, important in the coevolution process. As such, to call upon the institutional historical track is a fundamental aspect to materialize this study, for the recursive movement is indeed present in the coevolution. Another important point to make this research effective is that it is not possible to abdicate from the hologramatic view2 of this study, which considers the object, the isomorphic practices, part of the whole and this whole is also in the parts, therefore it is impossible to comprehend the object of study outside the context where it belongs. With this, as of the objective previously proposed, it is necessary to describe the characteristics of coevolution of the institutional changes related in 1998 and 2008; analyze the dynamic of the isomorphic mechanisms in its respective institutional change process; and describe the lessons learned which the isomorphic practices left to the IFRN, regarding its benefits and difficulties. All these transformations happened through coercive forces3 of the institutional environment. As of the Nineties, these forces became stronger, the environment became broader and more complex, with the emergency of new environmental factors. This study proposed to study the managing process and its practices, related to the micro environment, although it is required to articulate these actions, the demands and requirements from the macro environment. To make this research effective, semi structured interviews have been conducted with the managers who participated in both institutional change processes. In the results analysis, it has been possible to verify the particularity of each change, the one from 1998 with a strong normative action of the managers against coercive forces from the government for the search of recognition and the institutional legitimation and the one in 2008, which has been characterized by the normative action by managers in agreement with the coercive forces from the government, in favor of the government policy for the technological professional education. However, the results analysis it is possible to notice the evidence of a belonging feeling from the interviewed managers

Mudança dos processos de negócios e adequação da TI nas empresas em decorrência da implantação do sistema público de escrituração digital SPED: um estudo de casos múltiplos

Companies have always been organized by processes, often imperceptible to its employees. With the advancement of technology, organizational processes currently run an organization through computers, and thus generate immediate information that is available to each sector. With the objective of seeking business information in real time, the government created the SPED - Public System of Digital, which involves three subsystems, which are the Electronic Invoice, Digital Accounting Bookkeeping and Digital Tax Bookkeeping. This system is revolutionizing the business structures when gathering, in an innovative way, all information and interlinked business processes. For the implementation of SPED, a revision in the organizational processes is required, since the information is generated and is sent online to the government, without mistakes. Thus the study aimed to analyze the change brought about by the implementation of the Public System of Digital SPED in the main business processes. In order to do so, we have performed a multiple case study involving three companies in the state of Para, two operate in wholesale and one explores agribusiness. The Data collection was performed by accounting professionals, IT and managers. According to the results obtained, it was found that in two companies, the IT infrastructure was capable of deploying the new system without major problems, while one company had more difficulties to cope with the new system. However, all companies had to examine its processes to make the customizations needed to fit. It was also observed that there is no IT Governance in two companies. Therefore, we recommend the use of an appropriate model, not only for the implementation of SPED, but as a way to manage and extract better results from investment in information technology

Configurando a cidade contemporânea em Natal : os processos espaciais em Ponta Negra

This dissertation is about the spatial configuration in Natal and processes in the Ponta Negra neighborhood today. Ponta Negra has undergone a number of critical social and spatial changes due to tourism development after the 1990s. It is of special interest to consider the intensification of real estate investment after 2000, when the new airport terminal, located in the neighboring municipality of Parnamirim, was in use. Ponta Negra is the place where most tourists go to, so attracting considerable public investments. New agents of transformation have produced change in the neighborhood as well. The present study aims at analysing the spatial processes in this part of the city. Here, the spatial configuration that resulted from extended real estate investments, both public and private, in recent years, is analysed in detail. The study identifies the multually differentiated, however internally homogenous areas. The concepts of production of space, contemporanean urban development and spatial dynamics are discussed. The research is based on document analysis and field work. Results were plotted to maps and tables. A detailed analysis of the spatial processes in the Ponta Negra neighborhood is undertaken as a conclusion, considering the contemporanean global scenario

Interesses da habitação social : políticas e processos no Rio Grande do Norte

En 2003, le gouvernement brésilien (gestion Lula) a initié une nouvelle phase dans son histoire de l habitation, en intensifiant les constructions de logements sociaux au Brésil. Un tel accroissement a eut des répercussions tant en ville comme à la campagne, et fût marqué dans le Rio Grande do Norte, par la production a grande échelle d ensembles d habitations, dans les programmes de Gouvernement. Afin de viabiliser ces transformations, des instruments politiques, financiers et de gestion ont étés articulés conjointement, utilisant la répétition d une typologie d édification, comme modèle, accompagnée de la reproduction d une morphologie dans les constructions de logements sociaux. Afin de comprendre ce processus nous introduisons une recherche urbanistique et socio-économique du problème du logement social au Brésil, en cherchant à mettre en relation les aspects techniques avec les questions historique, professionnelles et culturelles, éléments complémentaires. Notre analyse cherche a identifier comment les politiques de gestion et financement officielles (administrées dans sa grande majorité par la Caisse Économique Fédérale -CEF-), influencent le processus de conception de projets, en provoquant les répétitions de type/morphologiques, déjà citées. Basée sur l observation directe au cour de deux expériences différenciées pour du logement social en milieu rural, au Rio Grande do Norte, nous montrerons aussi certaines limitations et possibilités des acteurs sociaux, face aux agents et politiques officielles pour le logement social au Brésil, proposant des solutions alternatives standardisées qui caractérisent le résultat des projets financées et gérés par la CEF.

O processo de urbanização de Mossorò: dos processos históricos à estrutura urbana atual

The general objective of this academic work is to analyze the relationship between the territorial division and the urban expansion process of Mossoró city, understood here as the production and occupation of space. The urban expansion in Mossoró, since its formation as settlement in 1772 until current days, identifies with the Brazilian urbanization process whose growth is determined by the capitalist development. Thus, the expansion was determined by several economical specializations imposed by the territorial division of work which occurs at an interregional level, and, sometimes at an international level. Then, each specialization determined a moment of the urban expansion of the city, as follows: a) The cattle farmer specialization, between 1772 and 1857, when the urban expansion was shy, is summarized to a commercial square that received goods from Aracati aiming to cover a wide rural area; b) The commercial emporium specialization, between 1857 and 1930, when the urban expansion took an important impulse with the concentration of public and private capitals; c) The salt industry and the agricultural-industrial exporter specialization inside a state of development policy, between 1930 and 1970, when the urban expansion, joined to the settlement of the working class in the urban soil, developed along an important axis -the railway; d) The render of services specialization inside a state of intervention policy, between 1970 and 1990, when the urban expansion was characterized by the accelerated growth rhythm, by the reuse of some spaces, and by space segregation of demanding people; e) The render of services policy inside a neoliberal state policy, since 1990 until current days, when the urban expansion reduced its rhythm abruptly, when only small alterations occurred in the existing spaces. It focused on social policies and on several slums eradication programs. Finally, the territorial structure is deeply articulated with others, no territorial, but economical, social and political, which happens at a national, regional and local rate. Only within a historical and conceptual panorama, it was possible to explain the urban expansion in Mossoró from its formation in 1772 until current days. Therefore, this work is a several discipline analysis of the urbanization process existing in Mossoró

Reconfiguração dinâmica de estratégias distribuídas em dispositivos foundation fieldbus para a otimização de processos na indústria do petróleo

The petrochemical industry has as objective obtain, from crude oil, some products with a higher commercial value and a bigger industrial utility for energy purposes. These industrial processes are complex, commonly operating with large production volume and in restricted operation conditions. The operation control in optimized and stable conditions is important to keep obtained products quality and the industrial plant safety. Currently, industrial network has been attained evidence when there is a need to make the process control in a distributed way. The Foundation Fieldbus protocol for industrial network, for its interoperability feature and its user interface organized in simple configuration blocks, has great notoriety among industrial automation network group. This present work puts together some benefits brought by industrial network technology to petrochemical industrial processes inherent complexity. For this, a dynamic reconfiguration system for intelligent strategies (artificial neural networks, for example) based on the protocol user application layer is proposed which might allow different applications use in a particular process, without operators intervention and with necessary guarantees for the proper plant functioning

Estimação e compensação de não linearidades inerentes aos atuadores dos processos industriais

The oscillations presents in control loops can cause damages in petrochemical industry. Canceling, or even preventing such oscillations, would save up to large amount of dollars. Studies have identified that one of the causes of these oscillations are the nonlinearities present on industrial process actuators. This study has the objective to develop a methodology for removal of the harmful effects of nonlinearities. Will be proposed an parameter estimation method to Hammerstein model, whose nonlinearity is represented by dead-zone or backlash. The estimated parameters will be used to construct inverse models of compensation. A simulated level system was used as a test platform. The valve that controls inflow has a nonlinearity. Results and describing function analysis show an improvement on system response

Controle preditivo neural aplicado à processos petroquímicos

A pesquisa tem como objetivo desenvolver uma estrutura de controle preditivo neural, com o intuito de controlar um processo de pH, caracterizado por ser um sistema SISO (Single Input - Single Output). O controle de pH é um processo de grande importância na indústria petroquímica, onde se deseja manter constante o nível de acidez de um produto ou neutralizar o afluente de uma planta de tratamento de fluidos. O processo de controle de pH exige robustez do sistema de controle, pois este processo pode ter ganho estático e dinâmica nãolineares. O controlador preditivo neural envolve duas outras teorias para o seu desenvolvimento, a primeira referente ao controle preditivo e a outra a redes neurais artificiais (RNA s). Este controlador pode ser dividido em dois blocos, um responsável pela identificação e outro pelo o cálculo do sinal de controle. Para realizar a identificação neural é utilizada uma RNA com arquitetura feedforward multicamadas com aprendizagem baseada na metodologia da Propagação Retroativa do Erro (Error Back Propagation). A partir de dados de entrada e saída da planta é iniciado o treinamento offline da rede. Dessa forma, os pesos sinápticos são ajustados e a rede está apta para representar o sistema com a máxima precisão possível. O modelo neural gerado é usado para predizer as saídas futuras do sistema, com isso o otimizador calcula uma série de ações de controle, através da minimização de uma função objetivo quadrática, fazendo com que a saída do processo siga um sinal de referência desejado. Foram desenvolvidos dois aplicativos, ambos na plataforma Builder C++, o primeiro realiza a identificação, via redes neurais e o segundo é responsável pelo controle do processo. As ferramentas aqui implementadas e aplicadas são genéricas, ambas permitem a aplicação da estrutura de controle a qualquer novo processo

Contribuição ao desenvolvimento de ontologias para processos petroquímicos : estudo de caso em uma planta DEA

In the last decades, the oil, gas and petrochemical industries have registered a series of huge accidents. Influenced by this context, companies have felt the necessity of engaging themselves in processes to protect the external environment, which can be understood as an ecological concern. In the particular case of the nuclear industry, sustainable education and training, which depend too much on the quality and applicability of the knowledge base, have been considered key points on the safely application of this energy source. As a consequence, this research was motivated by the use of the ontology concept as a tool to improve the knowledge management in a refinery, through the representation of a fuel gas sweetening plant, mixing many pieces of information associated with its normal operation mode. In terms of methodology, this research can be classified as an applied and descriptive research, where many pieces of information were analysed, classified and interpreted to create the ontology of a real plant. The DEA plant modeling was performed according to its process flow diagram, piping and instrumentation diagrams, descriptive documents of its normal operation mode, and the list of all the alarms associated to the instruments, which were complemented by a non-structured interview with a specialist in that plant operation. The ontology was verified by comparing its descriptive diagrams with the original plant documents and discussing with other members of the researchers group. All the concepts applied in this research can be expanded to represent other plants in the same refinery or even in other kind of industry. An ontology can be considered a knowledge base that, because of its formal representation nature, can be applied as one of the elements to develop tools to navigate through the plant, simulate its behavior, diagnose faults, among other possibilities

Efeito da perda de carga e calor no poço injetor no processo de drenagem gravitacional assistido com vapor e solvente

Nowadays, most of the hydrocarbon reserves in the world are in the form of heavy oil, ultra - heavy or bitumen. For the extraction and production of this resource is required to implement new technologies. One of the promising processes for the recovery of this oil is the Expanding Solvent Steam Assisted Gravity Drainage (ES-SAGD) which uses two parallel horizontal wells, where the injection well is situated vertically above the production well. The completion of the process occurs upon injection of a hydrocarbon additive at low concentration in conjunction with steam. The steam adds heat to reduce the viscosity of the oil and solvent aids in reducing the interfacial tension between oil/ solvent. The main force acting in this process is the gravitational and the heat transfer takes place by conduction, convection and latent heat of steam. In this study was used the discretized wellbore model, where the well is discretized in the same way that the reservoir and each section of the well treated as a block of grid, with interblock connection with the reservoir. This study aims to analyze the influence of the pressure drop and heat along the injection well in the ES-SAGD process. The model used for the study is a homogeneous reservoir, semi synthetic with characteristics of the Brazilian Northeast and numerical simulations were performed using the STARS thermal simulator from CMG (Computer Modelling Group). The operational parameters analyzed were: percentage of solvent injected, the flow of steam injection, vertical distance between the wells and steam quality. All of them were significant in oil recovery factor positively influencing this. The results showed that, for all cases analyzed, the model considers the pressure drop has cumulative production of oil below its respective model that disregards such loss. This difference is more pronounced the lower the value of the flow of steam injection
