The cooperative education begins with the very idea of cooperative. Aware of the peculiar characteristics of these organizational forms, where cooperation is proposed as an alternative to competition and individualism, the pioneers of the cooperative system themselves set that it will be one of the principles that define and support the cooperatives themselves. It transforms into one of the pillars of sustentation of the cooperative development, being constituent of the principles, as well as the explicit needs of these organizations. This work has as aim to discuss some aspects of the history, definitions and operation of cooperative education in the State of Minas Gerais- agricultural cooperatives and analyze the organizations that offer cooperative education. As methodological work for this analysis, there was first a survey, due to scarce available literature on the situation and to achieve more information about the problem, for it, it was directed questionnaires containing closed and open questions, addressed to all the agricultural cooperatives which it had access in the State. Second, it was performed a descriptive study of organizations that carry out cooperative education in the State of Minas Gerais, which were developed semi-structured interviews and documentary research. It is concluded that cooperative education is poorly developed in the Minas Gerais- agricultural cooperatives, although there is no single definition of what is the thematic or it should include. Therefore, the diversity of studied organizations allows the understanding of existence of multiple concepts of cooperative education, and also the observation of the variety of activities and public to whom theses activities are organized. It is possible to verify the presence of three focus areas - business management, social management and technical assistance to cooperatives members- in the contents that agricultural cooperatives identified as part of cooperative education. Among the organizations there are those that offer many of these contents, but with discrepancies, or sometimes with an emphasis of some contents and little attention given to the others. Yet, it is possible to visualize matches on the activities of cooperative education that are undertaken by these organizations, thereby causing duplicity of developed actions, however, not with the same approach. It´s verified the evidences of existence of a field, in Bourdieu´s way, multiple, diversified and in development, where diverse organizations with different profiles and purposes work.
A educação cooperativista nasce junto à própria ideia de cooperativa. Conscientes das características peculiares destas formas organizacionais, nas quais a cooperação se propõe como alternativa à competição e ao individualismo, os próprios pioneiros estabeleceram que ela será um dos princípios que sustentam e definem as próprias cooperativas. Como um dos pilares de sustentação do desenvolvimento cooperativo, é uma necessidade explícita destas organizações. O objetivo desta pesquisa é trazer para a luz do debate, aspectos relativos à história, definições e funcionamento da educação cooperativista nas cooperativas agrárias no Estado de Minas Gerais e analisar as organizações que atuam oferecendo educação cooperativista. Como trabalho metodológico para essa análise, realizou-se primeiro uma pesquisa exploratória, devido à escassa bibliografia disponível sobre a situação a ser observada e no intuito de alcançar maiores informações sobre o problema em questão. Para isso, foram encaminhados questionários, contendo questões fechadas e abertas, para todas as cooperativas agropecuárias às quais se teve acesso no Estado. Num segundo momento, foi realizada uma pesquisa descritiva das organizações que realizam educação cooperativista no Estado de Minas Gerais; para tanto foram realizadas entrevistas semiestruturadas, assim como pesquisa documental. Conclui-se que a educação cooperativista é escassamente desenvolvida nas cooperativas agrárias mineiras, embora não existindo uma única definição do que seja ou das temáticas que ela deva englobar. Assim, a heterogeneidade das organizações estudadas permite perceber a polissemia do conceito de educação cooperativista e observar também a variedade de atividades e públicos para os quais são organizadas essas atividades. Verifica-se a presença de três áreas privilegiadas nos conteúdos que as cooperativas agrárias identificam como fazendo parte da educação cooperativista: gestão empresarial, gestão social e assistência técnica aos cooperados. Dentre as organizações, existem aquelas que oferecem simultaneamente vários dos conteúdos mencionados, porém com discrepâncias, ou seja, às vezes com ênfase num destes conteúdos e pouca atenção dispensada aos demais. Ainda é possível visualizar coincidências nas atividades de educação cooperativista que são realizadas por essas organizações, ocasionando consequentemente sombreamento das ações desenvolvidas, embora não necessariamente com enfoque similar. Observamse indícios da existência de um campo no sentido de Bourdieu, múltiplo, diversificado e em crescimento, em que diversas organizações de distinto perfil e finalidade atuam.

O tema central desta tese é a Cooperativa ? Escola, a qual é aqui identificada como instituição de natureza social que, de um lado, propicia a formação ampla do indivíduo e, do outro, funciona como instrumento de geração de posto de trabalho (emprego) e renda. Contudo, a questão que desponta é qual a categoria de Cooperativa-Escola que potencializa o trabalho educativo e, simultaneamente, a geração de emprego e renda? Esta questão desloca a investigação para outro ângulo na busca de encontrar mecanismo que responda às indagações que emergiram do problema. Nesse sentido, elaborou-se um Modelo de Avaliação, partindo da concepção de que o processo de construção do conhecimento assenta-se na informação pré-existente e é nutrido pela relação teoria-empiria. Daí, foram definidos os constructos, figurados nos eixos básicos: Cooperativa e scola. No constructo Cooperativa foram identificados quatro vetores básicos: o administrativo, o econômico, o social e a participação. No constructo Escola foram istinguidos três fatores como determinantes do seu desempenho: ambiência fsica escolar, corpo docente e operacionalidade. Para efeito de validação, o modelo foi testado nas unidades escolares do Estado da Bahia. Os principais resultados foram: a maioria das unidades nasceu no modelo cooperativa de pais, posteriormente avançou para o misto; atualmente, a categoria cooperativa de docente surge com tendência de hegemonia; as melhores condições para funcionamento de Cooperativa-Escola são as cidades com população entre 41.000 e 135.000 habitantes e, inversamente do esperado, os municípios com maior contingente de população e renda não se constituem no principal mercado para operação. No constructo Cooperativa, a categoria docente foi a que apresentou maior eficiência na gestão, sobressaindo a unidade de Nazaré, na primeira colocação; no constructo Escola, a categoria cooperativa de pais foi a mais destacada, ficando a unidade de Barreiras com a melhor posição. Enfim, o Modelo de Avaliação proposto apresentou pertinência e mostrou condições de identificar as conexões dos fenômenos que integram o problema, revelando e decodificando a realidade em estudo.

Este trabalho, cujo tema é Uma contribuição à estruturação dos procedimentos e demonstrações contábeis das cooperativas Aplicação em uma cooperativa de trabalho, apresenta uma proposta de modificação na estrutura tanto dos procedimentos como das demonstrações contábeis das sociedades cooperativas. Partiu-se do problema que este tipo de sociedade vem enfrentando, ou seja, cálculo de impostos e contribuições com base na receita bruta, receita esta que não pertence à cooperativa, além da apresentação das informações contábeis dessas entidades, que por se tratar de sociedade sui generis, em função de seu aspecto doutrinário, não vem recebendo tratamento contábil de forma adequada. Iniciou-se a pesquisa com uma síntese da origem e da evolução do cooperativismo no mundo, seus precursores, a formação e evolução do pensamento cooperativista, de sua doutrina, dos seus princípios e normas, proporcionando assim o entendimento do funcionamento deste tipo de sociedade, seus aspectos doutrinários próprios, que a diferenciam do restante das sociedades, além de se conseguir identificar as transações que ocorrem entre elas e seus cooperados, assim como as transações de cada um separadamente, inclusive com a possibilidade de registrá-las. Posteriormente é realizado um estudo do sistema contábil para que, embasado nesta teoria, se consiga discutir e conceituar as receitas, despesas e custos das cooperativas e dos cooperados, bem como, ao mesmo tempo, definir quais os procedimentos contábeis corretos para estas operações. Com isso, buscou-se referencial teórico para sustentar as propostas de modificação tanto nos procedimentos como, por conseqüência, nas demonstrações contábeis das sociedades cooperativas, que foram realizadas de forma a mostrar as receitas, as despesas e os custos destas e de seus cooperados separadamente, fazendo com que a demonstração de resultado se apresente com o resultado da cooperativa e o patrimônio dela se apresente com sua forma própria, seguindo-se os aspectos doutrinários deste tipo de sociedade. Por fim, as propostas de modificações estudadas teoricamente são testadas e comparadas por meio de sua aplicação em demonstrações contábeis de uma cooperativa do ramo de trabalho.This research has as theme A contribution for the structuring of the proceedings and cooperatives accounting demonstrations - applied to a working cooperative and it shows a proposal of the structure changing not only the proceedings but also the accounting demonstrations of the cooperative society starting from the problem which this kind of society has been going through, that is, the taxation and contribution based on gross revenue, which doesnt belong to the cooperative, besides the accounting presentation of themselves, that deal with the society sui generis related to its indocrinate aspect, it hasnt been getting an accounting treatment appropriately. The research began with the origin synthesis and the cooperativism in the world and its forerunners, the formation and evolution of cooperative thought, its doctrine, its principles and rules, making possible the understanding of the function of this kind of society, its own doctrine aspects which makes the difference from the rest of the societies, besides getting to identify the transactions which occurs among them and their member of a cooperative, as well as the transaction of each one separatedly, including the possibilities of registering them. Afterwards it is achieved a study of the accounting system so that based on this theory we can think it over and name this revenues, expenses and costs of the cooperatives and their members, not to mention, at the same time define which are the correct accounting proceedings for these operations. With this, people searched for theorical referencial to back up the proposal of the changings in the proceedings as well as, by consequences, in the accounting demonstrations of the cooperative societies, which were achieved in a way to show their revenues and costs and also their members separatedly, making the demonstration of the results show along with the cooperative one and their corporate assets shows with its own way following the doctrine aspects of this kind of society. Finally, the proposal for the changing theorically studied, is tried and compared by means of its application in accounting demonstrations of a cooperative type of work.

O cooperativismo de crédito vem demonstrando um expressivo crescimento na última década no Rio Grande do Sul e neste sentido, o Sistema de Crédito Cooperativo – SICREDI RS tem contribuído significativamente para esse desenvolvimento. Constituído, atualmente, por 55 cooperativas e 447 Unidades de Atendimento, o SICREDI RS está presente atualmente em mais de 400 municípios e conta com mais de 700.000 associados. O vigoroso crescimento apresentado pelo SICREDI RS a partir de 1995 despertou o interesse pelo estudo das principais causas que estão contribuindo para tal. Desta forma, buscou-se verificar como os princípios cooperativos, em especial o da democracia e da intercooperação, estão sendo respeitados e qual a influência do Banco Central do Brasil na profissionalização da gestão das suas cooperativas.

Texto completo da fonteResumo:
O desenvolvimento de sistemas computacionais de apoio ao trabalho cooperativo tem se apresentado como a principal solução no sentido de ajudar grupos de pessoas que querem trabalhar de forma cooperativa e obter resultados melhores e de maneira mais rápida do que aqueles obtidos por esforço individual. A produção de documentos complexos como manuais de descrição técnica de produtos, manuais de usuários, tutoriais, relatórios técnicos, artigos, etc., é uma tarefa que se insere dentro deste contexto porque exige a colaboração de vários especialistas que participam da pesquisa ou do desenvolvimento do produto. De acordo com este contexto esta dissertação apresenta o projeto de um ambiente de suporte à autoria cooperativa que tem a finalidade de auxiliar um grupo de co-autores na construção de hiperdocumento complexos, mesmo estando fisicamente dispersos e interagindo de forma assíncrona. O ambiente oferece um conjunto de serviços de suporte tanto para a fase de planejamento quanto para a fase de execução ou escrita do hiperdocumento. Na fase de planejamento são discutidas as principais características do hiperdocumento que será criado, como a definição da estrutura lógica e a estrutura de apresentação, a atribuição das atividades entre os co-autores e a elaboração de um cronograma onde são detalhadas as tarefas necessárias e o tempo previsto para a conclusão das mesmas. Para auxiliar este planejamento são previstas ferramentas de apoio à realização de reuniões e à tomada de decisões e também um conjunto de ferramentas de apoio a criação da estrutura do hiperdocumento paralelamente com a atribuição das atividades de cada co-autor em relação aos elementos criados nesta estrutura. As ferramentas de apoio à fase de execução ou escrita enfatizam o compartilhamento de atividades e informações entre os co-autores bem como o suporte às interações entre eles. Elas terão como base o editor de hiperdocumentos estruturados THOT (desenvolvido no centro de pesquisas INRIA/CNRS - Grenoble, Fr.) que irá gerenciar as funções de edição. Estas ferramentas foram projetadas e desenvolvidas a nível de protótipo como uma extensão a este editor o que possibilitará seu uso de forma compartilhada por um grupo de co-autores. São apresentados nesta dissertação: i) o ambiente definido através de uma especificação informal sobre as funcionalidades previstas e, ii) características sobre a implementação de um protótipo deste ambiente.The development of computer supported cooperative work has been used as the main solution to help groups of people that want to work in a cooperative environment and to obtain better and faster results than those attained by individual effort. The production of complex documents, as technical description guides of products, users manuals, tutorials, technical reports, papers, and so on, is a task that is inserted in this context, because it requires the collaboration of several specialists that work in the reserach and development of the product. According to this context this dissertation presents the design of an environment to support cooperative authoring to help a group of co-authors to build a hyperdocument, even though they are physically dispersed and interacting in an assyncronous mode. This environment offers a collection of services to support as the planning phase as the hyperdocument execution or writing phase. In the planning phase are discussed the main characteristics of the hyperdocument that will be produced like definition of the logical and presentation structures, the attribuition of activities among co-authors and the elaboration of a schedulling where are detailed the necessaries tasks and the foressened time to conclude them. To help this planning are foressen meetings support tools, decision support tools and also a set of tools to support hyperdocument structure criation together with the activities attributions of each co-authors in relation with the elements created in this structure. The execution or writing phase support tools emphatize the sharing of activities and informations among the co-authors as the support to their interactions. These tools will be based on the THOT structured hyperdocuments editor (developed at INRIA/CNRS research center - Grenoble, FR.) that will manager the editions functions. These tools were projected and designed in a prototype level as extensions to this editor which will allow its use in a shared manner for a group of co-authors. It is presented in this dissertation: i) the environment definided by an informal specification about the foressen functionalities, and; ii) the implemantion characteristics on a environment prototype.

Texto completo da fonteResumo:
Por ser o cooperativismo um modelo de organização que promove desenvolvimento econômico e social, estudos de soluções que levem ao aumento de seu desempenho e a redução de seus problemas são cada vez mais importantes. Estas passam não só por melhorias na gestão e finanças das cooperativas, mas principalmente pelo incentivo à educação e a participação dos cooperados. Assim, o objetivo deste trabalho foi observar a relação entre educação cooperativista, participação e satisfação dos sócios de uma cooperativa de forma a contribuir para a elaboração de propostas e medidas que promovam o aumento do desempenho da cooperativa. Para tanto, realizou-se um estudo exploratório no qual foi desenvolvido um questionário próprio e lançou-se mão de um estudo de caso, escolhendo uma cooperativa do ramo agropecuário como objeto de análise. Os resultados apontam que apenas a escolaridade não garante a educação cooperativa, a qual, por sua vez, está relacionada com a participação de forma positiva. Também se constatou que a maior participação não está relacionada com a menor satisfação, como se esperava, e sim com o maior poder econômico. Tudo isso reforça a idéia de que se deve investir em ações específicas para a educação cooperativista como forma de aumentar a participação de todos, bem como o desempenho da cooperativa. Apesar de suas limitações, a pesquisa é ponto de partida para outros estudos nesta área além de contribuir para a construção de um modelo de análise.Because cooperatives are a model of organization that promotes economic and social development, studies of solutions that increase its performance and reduce its problems are very important. Those solutions involve not only improvement in managing and financing areas, but mostly the participation and the cooperative education. Thus, the objective of this work was to observe the relation between cooperative education, participation, and satisfaction of the members of a cooperative, as a way to contribute for the creation of proposals and plans that improve the performance of the cooperatives. To achieve this aim, it was done an exploratory study, using a questionnaire in a case study of an agricultural cooperative. The results show that high level of formal education does not implies high level of cooperative education, which is related with participation in a positive way. It also turned out that the higher participation is not connected with lower satisfaction, as imagined, but with higher economic power. All this reinforce the idea that is necessary investments in cooperative education to improve participation and cooperative performance. Despite its limits, the research is a start to others in the same area and contributes to the development of an analysis model.

Texto completo da fonteResumo:
In recent years, there has been a shift in among Kentucky rural electric cooperatives in regard to their stance on economic development. With this has been the employment of electric cooperative staff to help attract new industries and forge relationships with other local economic development-geared groups to facilitate growth. Cooperative businesses have historically proved their resilience and deep-rooted connections within the communities they serve. In exploring two similar-sized electric cooperatives in Kentucky located in two very different regions of the state, considering socio-economic status, and interviewing key informants with local affiliated economic development groups, it becomes evident that electric cooperatives possess a great potential to serve as a catalyst for economic development within their respective service territories.

Dissertação de Mestrado em Psicologia EducacionalA presente investigação, intitulada "Cooperação entre Professores: Realidade(s) e Desafios", tem como enfoque central o estudo dos factores que caracterizam o trabalho em equipa em contexto escolar. A abordagem ao estudo da cooperação entre professores obedeceu a duas temáticas. A primeira temática - "realidade(s) da cooperação" - visou: 1) o estudo do universo conceptual dos professores sobre cooperação; 2) descrever as práticas de cooperação existentes nas escolas, e; 3) identificar os factores que facilitam e inibem a cooperação entre professores. A segunda temática - "desafios da cooperação" - tem por objectivos: 1) analisar as percepções dos professores acerca dos impactos que a cooperação representa, e; 2) identificar as crenças dos professores sobre as exigências feitas pela cooperação. Este estudo envolveu 444 professores que exercem funções docentes em escolas dos 2o e 3o ciclos do continente português. O género feminino é o mais representativo, contribuindo para aproximadamente 75% do total de sujeitos inquiridos. O estudo da composição etária dos participantes mostra que no topo da distribuição figura o grupo etário que compreende o intervalo entre os 35 e 42 anos. A média de idades dos participantes é de cerca 40 anos. A análise da terceira variável usada para caracterizar os participantes - tempo de serviço docente - informa-nos que o intervalo situado entre os 7 e 25 anos de carreira é o mais representativo, contribuindo com mais de metade dos sujeitos (57%). A quarta e última variável ponderada é a área disciplinar, evidenciando-se o grupo disciplinar "humanidades" (41,4%) como o agrupamento de disciplinas com maior representação. As representações dos professores inquiridos sobre o conceito de cooperação ancoram em dois núcleos centrais - trabalho em equipa e partilha - que, por sua vez estão acopladas em 10 subcategorias. De acordo com cerca 60% dos professores inquiridos, cooperação significa trabalho em equipa, tendo-se ainda verificado que 93% desta categoria é explicada pela planificação, entreajuda, interdisciplinaridade e reflexão. Cooperar significa, igualmente, partilhar. Esta è a opinião expressa por 60% dos inquiridos, segundo a qual cooperação pressupõe, essencialmente, partilha de informação, experiências e objectivos. No que concerne às experiências de cooperação que ocorrem nas escolas, as opiniões dos professores foram arrumadas em duas categorias - «actividades científico-pedagógicas» e «actividades lúdico-pedagógicas». As actividades de carácter científico-pedagógico que decorrem nas escolas referem-se a experiências interdisciplinares, apoios educativos a alunos com necessidades educativas especiais, planificação em conjunto, cooperação com colegas na área de projecto, parcerias na área curricular não disciplinar de estudo acompanhado, construção de instrumentos de avaliação, organização curricular e participação na construção do projecto educativo da escola. As actividades de índole lúdicas com uma vertente pedagógica relatadas pelos professores abrangem as exposições, as visitas de estudo, os intercâmbios, as festividades que ocorrem nas escolas e as sessões em que são debatidos assuntos de variada ordem. É de ressaltar que a realização de debates, enquanto prática de cooperação, ocupa uma posição muito periférica no conjunto de exemplos de cooperação mencionados pelos professores. O estudo das variáveis que promovem a cooperação entre professores centrou-se nos seguintes factores: factores pessoais e profissionais, clima social dos grupos de trabalho, cultura organizacional das equipas, partilha e competências de comunicação, capacidade de gestão do stresse e flexibilidade. Os factores pessoais e profissionais que facilitam a cooperação envolvem a motivação, a receptividade ou abertura relativamente a opiniões diferentes, a capacidade organizativa, a flexibilidade, a afinidade profissional pessoal entre os elementos da equipa, o sentido de responsabilidade, a capacidade reflexiva sobre o trabalho, a capacidade para inovar, o sentido de humildade e o voluntariado. A atmosfera social nos grupos de trabalho é um factor que promove a cooperação entre professores e contempla a partilha de objectivos, o respeito mútuo entre os elementos da equipa, a capacidade para escutar as sugestões e opiniões dos outros, a qualidade do relacionamento entre os seus membros, a qualidade dos processos de comunicação que ocorrem dentro do grupo, a confiança depositada nos elementos que compõem a equipa e a existência de uma liderança que garanta a coesão do grupo. Cooperação entre Professores - Reaíidade(s) e Desafios vn Os factores organizacionais que facilitam a cooperação entre professores incluem a organização e gestão dos horários dos professores, a existência de recursos de suporte, a definição e distribuição de tarefas, o apoio dos órgãos directivos da escola e a existência de períodos avaliativos. Os professores consultados neste estudo conferem uma elevada importância à comunicação. As competências comunicacionais em que se regista uma importância mais moderada são a capacidade de partilha de informação no interior do grupo de trabalho e a utilização de estratégias para ajudar os colegas a exporem as suas opiniões, A maioria dos professores inquiridos admite que a posse de boas competências de gestão de stresse é favorável ao desenvolvimento de experiências de cooperação. A flexibilidade é o factor promotor da cooperação em que se registaram os valores médios mais baixos. Os obstáculos à cooperação estão agregados em três categorias - factores pessoais e profissionais, clima grupal e factores organizacionais. Os factores de ordem pessoal e profissional que actuam como obstáculos à cooperação entre professores são a desmotivação, a inflexibilidade, individualismo, intolerância face às opiniões de terceiros, a indisponibilidade para participar em experiências diferentes, incumprimento de tarefas estabelecidas, diferenças nos hábitos de trabalho, incompatibilidades pessoais, falta de segurança pessoal, o comodismo e a resistência à mudança. Os factores inibidores da cooperação relacionados com o clima relacional vivido nas equipas abrangem os conflitos interpessoais, a inexistência de objectivos, o desrespeito pelas ideias e opiniões, as variáveis que afectam a comunicação dentro do grupo de trabalho e o tipo de liderança. Os factores de natureza organizacional que emergem como factores inibidores à cooperação entre professores incluem a organização dos horários, a existência de recursos de apoio à Cooperação entre Professores - Realidade(s) e Desafios vm cooperação, a imposição ou obrigatoriedade da cooperação, a mobilidade dos professores, a eficácia das reuniões e a organização curricular. Os professores antecipam muitos impactos no ensino e na aprendizagem. A maior preocupação percepcionada pelos professores prende-se com o tempo que é exigido por esta modalidade de trabalho. A esmagadora maioria dos professores consultados afirma que a cooperação traz-lhes benefícios e que não representa custos acrescidos, assim como acarreta mais valias profissionais. A maioria dos professores também considera que serão respeitados os hábitos de trabalho, não receiam os desafios postos pela cooperação e admitem sentirem-se à-vontade e confiantes nas suas próprias capacidades para enfrentar os desafios inerentes à cooperação. A maioria dos professores está convicta que não surgirão constrangimentos que impeçam o desempenho e desenvolvimento profissional. Todavia, na perspectiva dos professores, a cooperação representa custos e recursos adicionais. A cooperação também produz efeitos negativos no orçamento das escolas e implica mudanças na gestão e organização dos horários dos docentes. Não obstante afirmarem que a cooperação interfere com a organização da escola, um elevado número de professores considera que as suas escolas dispõem de suficientes recursos para pôr em prática experiências de cooperação. Um número significativo de professores considera que o aumento de práticas de cooperação pode amplificar os problemas de comunicação. Para além de contribuir para o aumento de problemas de comunicação, na opinião dos professores o incremento da cooperação poderá afectar negativamente os relacionamentos entre professores, contribuindo para um clima relacional pouco favorável. Apesar de terem sido antecipados conflitos comunicacionais e dificuldades nos relacionamentos interprofissionais, cerca de dois terços dos professores considera que a cultura organizacional da escola a que pertencem se adapta facilmente aos desafios colocados pela cooperação.

Texto completo da fonteResumo:
Abstract In the last few years, location-awareness has emerged as a key technology for the future development of mobile, ad hoc and sensor networks. Thanks to location information, several network optimization strategies as well as services can be developed. However, the problem of determining accurate location, i.e. positioning, is still a challenge and robust algorithms are yet to be developed. In this thesis, we focus on the development of distance-based non-cooperative and cooperative algorithms, which is derived based on a non-parametric non- Bayesian framework, specifically with a Weighted Least Square (WLS) optimization. From a theoretic perspective, we study the WLS problem and establish the optimality through the relationship with a Maximum Likelihood (ML) estimator. We investigate the fundamental limits and derive the consistency conditions by creating a connection between Euclidean geometry and inference theory. Furthermore, we derive the closed-form expression of a distance-model based Cramér-Rao Lower Bound (CRLB), as well as the formulas, that characterize information coupling in the Fisher information matrix. Non-cooperative positioning is addressed as follows. We propose a novel framework, namely the Distance Contraction, to develop robust non-cooperative positioning techniques. We prove that distance contraction can mitigate the global minimum problem and structured distance contraction yields nearly optimal performance in severe channel conditions. Based on these results, we show how classic algorithms such as the Weighted Centroid (WC) and the Non-Linear Least Square (NLS) can be modified to cope with biased ranging. For cooperative positioning, we derive a novel, low complexity and nearly optimal global optimization algorithm, namely the Range-Global Distance Continuation method, to use in centralized and distributed positioning schemes. We propose an effective weighting strategy to cope with biased measurements, which consists of a dispersion weight that captures the effect of noise while maximizing the diversity of the information, and a geometric-based penalty weight, that penalizes the assumption of bias-free measurements. Finally, we show the results of a positioning test where we employ the proposed algorithms and utilize commercial Ultra-Wideband (UWB) devicesTiivistelmä Viime vuosina paikkatietoisuudesta on tullut eräs merkittävä avainteknologia mobiili- ja sensoriverkkojen tulevaisuuden kehitykselle. Paikkatieto mahdollistaa useiden verkko-optimointistrategioiden sekä palveluiden kehittämisen. Kuitenkin tarkan paikkatiedon määrittäminen, esimerkiksi kohteen koordinaattien, on edelleen vaativa tehtävä ja robustit algoritmit vaativat kehittämistä. Tässä väitöskirjassa keskitytään etäisyyspohjaisten, yhteistoiminnallisten sekä ei-yhteistoiminnallisten, algoritmien kehittämiseen. Algoritmit pohjautuvat parametrittömään ei-bayesilaiseen viitekehykseen, erityisesti painotetun pienimmän neliösumman (WLS) optimointimenetelmään. Väitöskirjassa tutkitaan WLS ongelmaa teoreettisesti ja osoitetaan sen optimaalisuus todeksi tarkastelemalla sen suhdetta suurimman todennäköisyyden (ML) estimaattoriin. Lisäksi tässä työssä tutkitaan perustavanlaatuisia raja-arvoja sekä johdetaan yhtäpitävyysehdot luomalla yhteys euklidisen geometrian ja inferenssiteorian välille. Väitöskirjassa myös johdetaan suljettu ilmaisu etäisyyspohjaiselle Cramér-Rao -alarajalle (CRLB) sekä esitetään yhtälöt, jotka karakterisoivat informaation liittämisen Fisherin informaatiomatriisiin. Väitöskirjassa ehdotetaan uutta viitekehystä, nimeltään etäisyyden supistaminen, robustin ei-yhteistoiminnallisen paikannustekniikan perustaksi. Tässä työssä todistetaan, että etäisyyden supistaminen pienentää globaali minimi -ongelmaa ja jäsennetty etäisyyden supistaminen johtaa lähes optimaaliseen suorituskykyyn vaikeissa radiokanavan olosuhteissa. Näiden tulosten pohjalta väitöskirjassa esitetään, kuinka klassiset algoritmit, kuten painotetun keskipisteen (WC) sekä epälineaarinen pienimmän neliösumman (NLS) menetelmät, voidaan muokata ottamaan huomioon etäisyysmittauksen harha. Yhteistoiminnalliseksi paikannusmenetelmäksi johdetaan uusi, lähes optimaalinen algoritmi, joka on kompleksisuudeltaan matala. Algoritmi on etäisyyspohjainen globaalin optimoinnin menetelmä ja sitä käytetään keskitetyissä ja hajautetuissa paikannusjärjestelmissä. Lisäksi tässä työssä ehdotetaan tehokasta painotusstrategiaa ottamaan huomioon mittausharha. Strategia pitää sisällään dispersiopainon, joka tallentaa häiriön aiheuttaman vaikutuksen maksimoiden samalla informaation hajonnan, sekä geometrisen sakkokertoimen, joka rankaisee harhattomuuden ennakko-oletuksesta. Lopuksi väitöskirjassa esitetään tulokset kokeellisista mittauksista, joissa ehdotettuja algoritmeja käytettiin kaupallisissa erittäin laajakaistaisissa (UWB) laitteissa

Texto completo da fonteResumo:
Essa pesquisa procura avaliar a contribuição do Programa Nacional de Alimentação Escolar (PNAE) na criação de novos mercados para os produtores locais junto a experiência da cooperativa COOPAFI do município de Capanema, uma organização que é referência em inúmeras estratégias de acesso ao mercado institucional para viabilizar a comercialização de produtos dos seus agricultores familiares filiados, mas: Teria o PNAE impactado positivamente a receita desses agricultores? Onde e como os agricultores conseguiriam comercializar os mesmos produtos se não fossem associados à cooperativa? Portanto, a primeira hipótese é de que os agricultores que acessam o PNAE no município de Capanema tiveram efetivo aumento de receita. E a segunda é de que os agricultores não teriam outro meio para conseguir comercializar no mercado local/regional em quantidade próxima ou similar se não fossem cooperados. Desta maneira procurar-se-á compreender qual o papel do PNAE no fortalecimento da agricultura familiar e suas organizações. Em específico, procurar-se-á: (1) investigar os motivos da adesão e permanência dos agricultores no PNAE e compreender a forma como os agricultores se inseriram no PNAE; (2) verificar se o PNAE promoveu a melhoria das condições de vida da população envolvida; (3) identificar quais são os alimentos adquiridos pela COOPAFI – Capanema no atendimento de suas demandas locais/regionais para perceber as motivações e percepções dos mesmos frente as possibilidade de geração de renda não apenas no curto prazo; (4) descrever o perfil socioeconômico dos agricultores participantes do PNAE verificando a influência dessa política na inserção dos agricultores familiares em novos mercados. A pesquisa constatou um efetivo aumento de receita entre os cooperados, o que evidencia o papel do PNAE no fortalecimento da agricultura familiar, entretanto, não foi possível caracterizar a extrema dependência dos agricultores à cooperativa, mas, uma inserção em novos mercados que propiciou a diversificação da produção; aumento da quantidade produzida; a qualificação do agricultor para a melhoria da qualidade dos produtos; a especialização do trabalho na agroindústria e o conhecimento de novos canais de comercialização.This research evaluates the contribution of the National School Feeding Programme (PNAE) in creating new markets for local producers to the experience of cooperative COOPAFI the municipality of Capanema, an organization that is a reference in many strategies to access the institutional market to enable the marketing of products of its affiliated farmers, but: Did the PNAE positively impacted the revenue from these farmers? Where and how the farmers to sell their products if they were not associated with the cooperative? Therefore, the first hypothesis is that farmers who access the PNAE in the municipality of Capanema had effective increase income. And the second is that farmers would have no other means to achieve market in the local / regional market in close or similar amount if they were not members. This way will be sought to understand the role of PNAE in strengthening family agriculture and its organizations. In particular, efforts will be made: (1) investigate the reasons for accession and farmers remain in the PNAE and understand how farmers were inserted in PNAE; (2) verify that the PNAE helped improve the living conditions of the population involved; (3) identify which foods purchased by COOPAFI - Capanema in meeting their local / regional demands to understand the motivations and perceptions thereof forward the possibility of generating income not only in the short term; (4) describe the socioeconomic profile of participants PNAE farmers and the influence of this policy on the integration of family farmers in new markets. The survey found an effective increase in revenue among the cooperative, which highlights the role of PNAE in strengthening family farming, however, was not possible to characterize the extreme dependence of farmers to the cooperative, but an insert into new markets that led to the diversification production; increase in the quantity produced; the qualification of the farmer to improve the quality of products; the specialization of labor in the agricultural industry and the knowledge of new marketing channels.

Texto completo da fonteResumo:
The performance and reliability of wireless communication links can be improved by employing multiple antennas at both ends, thereby creating multiple-input multiple-output (MIMO) channels. However, once multiple co-channel users are added to the system it can be difficult to provide as many receive antennas as transmit antennas, resulting in a so-called overloaded (rank-deficient) system. Under overloaded conditions, maximum likelihood (ML) detection works well, but its exponential complexity prohibits its use and suboptimal linear detectors perform poorly.
In this thesis, new signal processing techniques for multi-user overloaded systems using hybrid automatic repeat request (HARQ) protocols are investigated. The HARQ retransmissions are used to form virtual receive antennas, which can efficiently transform an overloaded system into a critically loaded system (i.e. a system with an equal number of transmit and receive antennas).
In the first part of the thesis, a multi-user non-cooperative overloaded system is considered. At first, it is demonstrated that the suboptimal linear minimum mean square error (MMSE) detector leads to significant performance degradation compared to an ML detector for such systems. To overcome this drawback, two multi-user transmission schemes are proposed that work well under overloaded conditions. The proposed schemes allow us to apply linear multi-user detection (MUD) algorithms without requiring additional antennas or hardware chains. Monte-Carlo simulations demonstrate that the proposed schemes can result in significant gains in terms of bit-error-rate (BER) and dropped packet performance.
In the second part, the performance of multiple HARQ processes for a two-hop multi-source multi-relay decode-and-forward (DF) relaying network with no direct link are analyzed. Dealing with multiple HARQ processes at each relay, a retransmission scheme is proposed that utilizes virtual antennas to achieve increased receive diversity and improved throughput compared to traditional orthogonal (time division) retransmissions. A novel forwarding strategy at the relay(s) to destination link is proposed with the objective of further improving throughput. Finally, the end-to-end outage probability and throughput efficiency of the proposed retransmission and forwarding schemes are found analytically and confirmed with Monte-Carlo simulations.

Texto completo da fonteResumo:
In this research Pythagorean Hodograph based path planning and camera based cooperative perception are investigated separately and then these two entirely separate areas (Path Planning and Perception) are integrated for the application in online pop-up obstacle locating & avoidance and moving target tracking & surveillance in dynamic environments. The path planning is integrated with the cooperative perception to deal with the challenges posed by the dynamic environment. The aim of this integration is to achieve maximum autonomy required to execute a mission autonomously by multiple fixed wings UAVs in a dynamic environment. During the mission execution, the cooperating UAVs start from some initial location in the operating environment and finish at some final location while trying to achieve the mission’s objectives in a cooperative way. Naturally planning a feasible (safe and flyable) path for each participating UAV from initial position to a final location becomes a compulsory task of mission planning. For fixed wing UAVs flyable paths mean, paths which have tangential and curvature continuity and which obey the kinematic and dynamic constraint of the UAVs. In this research an algorithm based on Pythagorean hodograph curves is developed and used for planning feasible (safe and flyable) paths. The Pythagorean hodograph (PH) yields paths of exact length having tangential and curvature continuity. These continuous paths are made flyable for the UAVs by imposing the kinematic constraints of the UAVs. These constraints are imposed by the curvature and torsion manipulation of the planned paths. The safety of these paths is ensured by making it free of inter collisions between the vehicles and collisions with the known obstacles. These feasible paths are known as the initial paths or reference trajectories. In this research the operating environment is assumed to be dynamic in which changes are taking place at all times. Each UAV taking part in the mission is equipped with a vision sensor to perceive these changes continuously in a cooperative way. As the mission is assumed to be executed in day light, therefore light intensity video camera is used as a vision sensor. A perception algorithm for locating an object cooperatively in 3D is developed in this research. This algorithm is based on the optimization of errors in target position acquired by the on board camera. The algorithm is used by the cooperative perception system for optimal position estimation of the object in the scene. The target position information between the participating UAVs is exchanged through wireless communication for data fusion purposes. After developing efficient algorithms for path planning and cooperative perception, the two algorithms are integrated to be used in reactive obstacle avoidance and target tracking. During the mission, when the UAVs start their flight on the reference trajectories generated by the path planning algorithm, the perception algorithm comes into action. During the travel on these paths if the perception system of any of the UAVs detects an interrupting obstacle which was not known a priori in the map, then the exact location of this obstacle is determined with the help of the perception algorithm in a cooperative way. Using the location of the interrupting obstacle determined by the perception algorithm the path planning algorithm plans an evasive manoeuvre for the corresponding UAV to avoid it. After avoiding the obstacle the UAV comes back to its reference trajectory as soon as possible. In the operation of surveillance and tracking during the mission, the onboard perception algorithm locates an object of interest dynamically and the Pythagorean hodograph (PH) path planner uses this location to generate the paths for the cooperating UAVs to keep in close proximity of the target. In this case the close proximity of the target means to follow the moving target in such a way that it remains in the fields of views of the UAVs cameras at any time. By this integration of path planning and cooperative perception the continuous surveillance and tracking of the target was made possible even when the individual UAV experiences failure. During this research the mid flight obstacle locating & avoidance, and target surveillance & tracking have been successfully achieved by the integration of the path planning and cooperative perception. The purpose of this integration is to achieve an enhanced autonomy for the cooperating group of UAVs to increase the probability of their survival in mission being executed in dynamic environments.

Resumo: A Mondragón Corporação Cooperativa (MCC) - por meio das instituições e normas criadas desde o seu início (nos anos 1950) e, a partir dos anos 1990, dos investimentos em novas plantas de produção ou alianças com outras empresas fora da Espanha, incluindo o Brasil - representa hoje o maior empreendimento cooperativo de produção no mundo. Como negócio, a internacionalização da Mondragón é um sucesso, entretanto, expõe diversas contradições em relação ao ideário e princípios cooperativistas. Pesquisamos a internacionalização da Mondragón em uma filial instalada no Brasil comparando-a com a sua sede na Espanha e, a partir disso, consideramos que o processo de internacionalização da MCC e a forma como se organiza fora do País Basco é uma escolha pragmática e econômica, capaz de viabilizar a competitividade das cooperativas no mercado, além de manter e financiar as suas estruturas solidárias no País Basco. No entanto, essa atuação internacional degenera os ideais do cooperativismo, pois, insere a divisão entre capital e trabalho, por meio da ampla utilização e exploração do trabalho assalariado
Abstract: Mondragón Cooperative Corporation (MCC) - through the institutions and rules created since its beginning (in the 1950's) and, since 1990, through the investments in new production plants or alliances with other companies outside Spain, including Brazil - represents nowadays the biggest production cooperative enterprise in the world. As a business, Mondragón's internationalization is a success, however, it exposes a lot of contradictions in relation to the cooperative ideals and principles. We have researched Mondragón's internationalization in a branch installed in Brazil comparing it to its head office in Spain and from this, we considered that MCC internationalization process and the ways it is organized outside the Basque Country is a pragmatic and economical choice, which can enable the competition among the cooperatives in the market, besides keeping and funding its solidary structures in Basque Country. Nevertheless, this international acting degenerates the cooperative ideals since it inserts the division between capital and work, through the wide use and exploration of wage labor

Texto completo da fonteResumo:
The aim of this research is to examine the current situation of university libraries in the GCC countries identifying the problems and difficulties being faced by them and suggest means and ways by which an effective library cooperation may solve these problems. A general description of library cooperation is given, including that in developing countries and in the Arab world. Apart from literature sources the material for this research was obtained by questionnaire, personal visits to university libraries and some related research institutions in the countries concerned and by some personal observations and experience. The development of library and information services in general in the CCC countries is examined, but particularly various features of university libraries, from administration to user services. University library resources, technical services, and existing cooperative activities are also discussed in detail. There are some major issues which are related to library cooperation such as financial resources, adequacy of library collections, collection development practices, uniform standards of technical processing of library materials, availability of bibliographical apparatus and experienced professional manpower. The analysis of these issues brought out factors which should motivate individual libraries to engage in a library cooperation and resource sharing network. There is no practical or well organised resource sharing programme among university libraries in the GCC countries, even the existing marginal activities are not satisfactory to all university libraries concerned. This is mainly due to the absence of a well organised central agency which should take the lead to implement a well developed cooperative model for library cooperation in the region. The various professional meetings which have been organised at a regional level emphasised the importance of establishing effective cooperative links among university libraries in the Gulf region, but little implementation of these proposals have resulted so far. With the current political situation in the Gulf region and with the limitation on financial resources, the need for effective library cooperation is emphasised now more than ever before. Therefore, this research makes some practical recommendations emphasising the need for a central agency responsible for library cooperation programmes and proposing a model for an effective resource sharing network among university libraries in the GCC countries in the hope of improving the existing situation.

Texto completo da fonteResumo:
Thesis (M.Dev.) --University of Limpopo, 2013Agricultural cooperatives have been widely promoted as a vehicle for smallholder agricultural development in South Africa. As a result, agricultural co-operative registrations in South Africa are increasing. However, research suggests that South African co-operatives have generally not been effective, successful and functional. This study has investigated the challenges facing agricultural cooperatives in the Greater Tzaneen Municipality. It is expected that identification of these elements may enable institutions that offer support to cooperatives make better decisions to improve primary agricultural cooperatives support. Understanding of these elements could inform the efforts for members of cooperatives to achieve their set objectives and thus improve agriculture cooperative, employability, functionality and profitability. A case study of the Nkomamonta Agricultural Primary Cooperative in the Greater Tzaneen Municipalities is used. It is composed of fifteen agricultural cooperative which were purposively selected for the study because they were nearby, they are a pilot agricultural cooperative in the municipality and which are also not functioning as expected. The sample also included the purposively selected members, customers of these agricultural cooperative, workers, Greater Tzaneen Municipality, Local SEDA and LIBSA to explore the differences and provide insight to the knowledge, opinions and challenges that are facing agricultural cooperatives. One-on-one interviews were carried out with co-operative members as well as focus group discussions with customers, members of the cooperatives, workers, the Municipal officials, SEDA and LIBSA. A framework for analysing the challenges agricultural cooperatives with reference to the Nkomamonta cooperative case study was developed using literature of objectives of agricultural cooperatives, challenges which were identified by other researchers and success factors of smallholder agriculture. According to this study, farmers’ activities are hampered by a number of constraints. Production capability of the fifteen primary cooperatives is hampered by resource constraints such as lack of access to land (in one cooperative), machinery and equipment, finances and information relevant to production. Marketing, transportation, poor infrastructure and the elderly age of some cooperative members and issues related to free-rider syndrome were part of the problems that were identified. Low capability of some of the fifteen cooperatives to mobilise resources, use the limited resources available and low capability to manage institutional arrangements rendered the cooperatives ineffective in achieving their set objectives. The study recommends strategies for ensuring that the challenges facing agricultural cooperatives are minimised to better their services in the community. These include strategies for addressing internal and external issues affecting the cooperatives. Direct intervention from government is recommended to improve production through revising land allocation systems which made Kulani Agricultural Cooperative not to have land for growing crops. Jerry Jeff and Nwa Rex went out of action for eight months due to renovation of neighbourhood inorganic farms by the Department of Agriculture. Another strategy would entail improving extension services and follow up and strict monitoring of effective use of government resources provided to farmers. Responding and action taking when disaster has struck the agricultural cooperative by Government is also a plausible strategy. Access and training to relevant technologies to improve the processing and packaging capabilities of cooperatives should improve. Marketing and management activities should be supported through provision of improved infrastructure and relevant training. Farmers themselves should consider assisting one another especially regarding land issues as it was discovered that 67 hectares lay unutilised while the farmer next door needed land. Farmers should also engage in value added activities, and improve marketing programs and cost-effective distribution mechanisms.

Texto completo da fonteResumo:
Les projets de conception deviennent de plus en plus complexes et multidisciplinaires en termes d’organisation. Ces projets sont menés actuellement d’une manière collaborative. La connaissance coopérative (liée à la négociation et à l’organisation) produite dans ce type de projets est généralement perdue. Par ailleurs, la gestion des connaissances permet à une entreprise de réutiliser l’expérience afin d’améliorer l’apprentissage organisationnel. Plusieurs méthodologies sont définies pour recueillir les connaissances métier. Cependant, ces approches présentent des limites pour recueillir et modéliser les connaissances coopératives. Un acteur ne peut pas expliquer globalement l’activité coopérative sans préjugé. Comment réutiliser la connaissance coopérative des projets de conception devient un défi en gestion de connaissances. Dans ma thèse « Découverte des connaissances coopératives à partir des activités coopératives : application sur les projets de conception », le terme « «découverte des connaissances » est redéfinit selon la méthodologie de l’ingénierie des connaissances et la gestion des connaissances. La nature de la connaissance coopérative est étudiée, ensuite une nouvelle approche de classification est proposée afin de découvrir la connaissance coopérative dans les activités coopératives. Cette approche est également élaborée dans le contexte de projet de conception. Des tests sur des projets en ingénierie de logiciel, en éco-conception et en conception mécanique sont réalisésModern design projects tend to be more and more complex and multi-disciplinary in terms of both organization and process. Knowledge management enables a company to reuse its experience in order to improve organizational learning. Several knowledge engineering methods are defined to obtain expert knowledge. However, no knowledge approaches have succeeded to extract cooperative knowledge due to its particular features: cooperative knowledge is produced in cooperative activities; no single actor can claim to explain globally the cooperative activity with no personal bias. How can we reuse cooperative design project knowledge is the new challenge. In my thesis “knowledge discovery from cooperative activities, application on design projects”, the term “knowledge discovery” is redefined according to knowledge engineering approaches, and guided by the spirit of knowledge management. The nature of cooperative knowledge is studied and a novel approach of classification is proposed to discover knowledge from cooperative activities, and it is further elaborated in the context of design projects, examples on software engineering, eco-design and mechanical design are demonstrated

Previous issue date: 2007-10-17The present study describes the diverse socioeconomic aspects that contribute to family income increase of cooperative members at the Cooperativa Agropecuária do Cariri Coapecal. The idea of cooperative firstly appeared in the nineteenth century when the first cooperative was founded in Rochdale, Manchester, Britain in response to the Industrial Revolution advance that had introduced the steam machine to replace manpower available then. The method used in the research was a case study including a descriptive and bibliographic field survey. A population of 900 cooperative members were involved in the study, being 187 out of them used as a sample for the investigation. A questionnaire involving three aspects was used to collect the data in the survey. The first aspect containing 8 questions related to the socioeconomic profile of cooperative members; the second with 6 questions referred to property, being the third aspect with 9 questions about cattle raising. The whole questionnaire comprised of 23 closed questions aiming to estimate the increase rate in the family income of the people surveyed. Finally, after compiling and interpreting the variables of the research, the study showed there was, indeed, an increase in the family income of those members, and it confirmed that cooperativeness is an effective alternative to reach this goal. Thus, it is expected that cooperative managers ponder over this reality and that they be willing to meet their members´ requests.
O presente estudo teve por objetivo analisar os principais fatores que contribuíram para a elevação da renda familiar dos cooperados da Cooperativa Agropecuária do Cariri Coapecal. O cooperativismo surgiu no século XIX, com a fundação, em 1844, da primeira cooperativa, em Rochdale, bairro de Manchester na Inglaterra, em resposta ao avanço da Revolução Industrial, que introduzia a máquina a vapor em substituição a mão-de-obra disponível na época. O método utilizado foi o estudo de caso. A pesquisa realizada quanto ao objeto foi do tipo bibliográfica e de campo e quanto aos fins a descritiva. O universo pesquisado foi composto por uma população de 900 cooperados, sendo destes retirada uma mostra de 187 cooperados. Utilizou-se como instrumento de coleta de dados a aplicação de questionário, com vinte e três perguntas fechadas, visando delinear o perfil socioeconômico dos cooperados, como também identificar os aspectos relacionados com a propriedade e as atividades desenvolvidas referente à pecuária, onde se buscou aferir o grau de elevação da renda familiar dos pesquisados. E por fim, depois de agrupadas e interpretadas às variáveis inerentes a referida pesquisa, o presente estudo demonstrou que a maioria dos pesquisados teve realmente comprovada à elevação na sua renda familiar, confirmando que é o cooperativismo uma alternativa na microrregião do cariri oriental paraibano, para se alcançar esse objetivo. Desse modo, esperamos que os gestores da Cooperativa reflitam e busquem atender às reivindicações feitas pelos seus cooperados.

Because of this research´s intensity and extension, a valuable framework to identify, analyse and describe the competencies of credit cooperatives can be proposed. Furthermore, the profound insights into the area of investigation, combined with the interesting aspects, linked to the case-study-bank, allowed the researcher to develop additional correlated propositions. Managers of credit cooperatives as well as of other banks can profit from this study. Understanding the basic rules may enhance the possibility of transfetring the results and consequently to discover thus far unexplored potentials and new ideas for navigating through the current challenging situation. crisis rather well. This study, therefore, aims at identifying, analysing and describing competencies of a credit cooperative, that may potentially contribute to ´solve the problems´, banks are continuously faced with. The complexity and difficulty of identifying competencies necessitates the application of an interpretive paradigm to this study, which enables the researcher, as well as managers of CCs and banks to ´dig deeper into´ and better understand the area of investigation and thus identify, analyse and describe competencies. An extensive literature research, including the elucidation of specific aspects, was conducted and subsequently, a concept developed that facilitated the structuring of the data gained from the empirical study. This empirical study builds on a comprehensive case study, which involved an especially interesting credit cooperative in Germany. The concept, developed from the theoretical research derived from the literature, was applied to the collected data. The applied research technique resulting from the interpretive paradigm supports the significance of the results, as it allows to a step-by-step and thus better understanding of the ´rules of the game´ prevalent in the case-study bank.
As competências de organizações são de importância vital para elas porque representam o motor de competitividade da organização. A ´resource-based theory´(teoria fundamentado aos recursos) como a teoria subjacente e a ´competencebased-view´ (visão fundamentado aos competências) em particular, destacam o atributo de solução do problema de competências.Isto é especialmente relevante para os bancos, que enfrentam desafios ligados aos desenvolvimentos tecnológicos. Atualmente, os bancos estão enfrentando dificuldades consideráveis devido à crise financeira e econômica.As cooperativas de crédito, por outro lado, têm tido êxito em manipular os desafios impostos pelos desenvolvimentos tecnológicos e também parecem estar lidando com a crise atual muito bem.Este estudo, portanto, pretende identificar, analisar e descrever as competências de uma cooperativa de crédito, que pode potencialmente contribuir para ´resolver os problemas´, que os bancos continuamente enfrentam. A complexidade e dificuldade de identificar as competências, exige a aplicação de um paradigma interpretativo para este estudo, que capacita o pesquisador, assim como os gestores das cooperativas de crédito e dos bancos, a ´cavar mais fundo´ e melhor compreender a área de investigação e assim identificar, analisar e descrever competências.Uma extensa pesquisa de literatura, incluindo a elucidação de aspectos específicos,foi conduzida e subseqüentemente, um conceito foi desenvolvido que facilitou a estrutura dos dados obtidos no estudo empírico.Este estudo empírico baseia-se num estudo de caso abrangente, que envolveu uma cooperativa de crédito especialmente interessante na Alemanha. O conceito,desenvolvido da pesquisa teórica derivada da literatura, foi aplicado aos dados coletados. A técnica aplicada de pesquisa resulta do paradigma interpretativo apóia a importância dos resultados, assim como permite um passo a passo e assim um melhor entendimento das ´regras do jogo´ predominante no banco estudado.Finalmente, os resultados de cada passo e compreensão das competências identificadas, inclusive o assim chamado ´poder de ativação´, são apresentados.Devido à intensidade desta pesquisa, uma estrutura valiosa para identificar, analisar e descrever as competências das cooperativas de crédito pode ser proposta. Além do mais, as introspecções profundas na área de investigação, combinadas aos aspectos interessantes, ligado ao estudo de caso do banco, permitiu que o pesquisador desenvolvesse propostas correlacionadas adicionais. Gestores de cooperativas de crédito assim como de outros bancos podem se beneficiar deste estudo. A compreensão das regras básicas pode aumentar a possibilidade de transferência de resultados e, portanto, descobrir possíveis até aqui inexplorados e novas idéias para lidar com a situação de desafios atual.

Texto completo da fonteResumo:
Interval uncertainty affects our decision making activities on a daily basis making the data structure of intervals of real numbers more and more popular in theoretical models and related software applications. Natural questions for people or businesses that face interval uncertainty in their data when dealing with cooperation are how to form the coalitions and how to distribute the collective gains or costs. The theory of cooperative interval games is a suitable tool for answering these questions. In this thesis, the classical theory of cooperative games is extended to cooperative interval games. First, basic notions and facts from classical cooperative game theory and interval calculus are given. Then, the model of cooperative interval games is introduced and basic definitions are given. Solution concepts of selection-type and interval-type for cooperative interval games are intensively studied. Further, special classes of cooperative interval games like convex interval games and big boss interval games are introduced and various characterizations are given. Some economic and Operations Research situations such as airport, bankruptcy and sequencing with interval data and related interval games have been also studied. Finally, some algorithmic aspects related with the interval Shapley value and the interval core are considered.

Texto completo da fonteResumo:
In this thesis project, we consider the cooperative control of multi-agent systems under limited communication between the individual agents. In particular, quantized values of the relatives states between neighboring agents are used as the control parameters for each agent. As an introductory part, the theoretical framework for the distributed consensus problem under perfect communication is reviewed with the focus on the system stability and convergence. We start from the common problem setup that single integrator agents with a static tree communication topology, where the stability constraints and convergence guaranty are derived for dierent quantization models: uniform, logarithmic and dynamic. Then the conclusions are extended to switching tree topologies, tree topologies with disconnected time intervals and nally general undirected graphs. The control performance like onvergence rate and the area of convergence set are compared between systems with and without quantization eects, and also among the systems with dierent quantizers. Furthermore, similar techniques are applied to other system dynamics with quantized control inputs. We investigate additional constraints on the stability of the corresponding discrete time system due to the presence of quantization eects. Explicit upper bounds on the sampling time that guarantee convergence are derived. As expected, the sampling frequency has to be increased accordingly under dierent quantization models. The multi-agent system composed of second-order agents under general undirected communication graphs is also taken into account with quite dierent analytical tools. Finally we switch to an alternative model that takes the relative quantized states as control parameters instead. Distinctive convergence properties are found between these two models and detailed comparisons are made. Throughout this report, all results obtained are supported by numerical simulations.

Texto completo da fonteResumo:
In this thesis we develop dynamic cooperative investment schemes in discrete and continuous time. Instead of investing individually, several agents may invest joint capital into a commonly agreed trading strategy, and then split the uncertain outcome of the investment according to the pre-agreed scheme, based on their individual risk-reward preferences. As a result of cooperation, each investor is able to get a share, which cannot be replicated with the available market instruments, and because of this, cooperative investment is usually strictly profitable for all participants, when compared with an optimal individual strategy. We describe cooperative investment strategies which are Pareto optimal, and then propose a method to choose the most ‘fair’ Pareto optimal strategy based on equilibrium theory. In some cases, uniqueness and stability for the equilibrium are justified. We study a cooperative investment problem, for investors with different risk preferences, coming from expected utility theory, mean-variance theory, mean-deviation theory, prospect theory, etc. The developed strategies are time-consistent; that is the group of investors have no reasons to change their mind in the middle of the investment process. This is ensured by either using a dynamic programming approach, by applying the utility model based on the compound independence axiom. For numerical experiments, we use a scenario generation algorithm and stochastic programming model for generating appropriate scenario tree components of the S&P 100 index. The algorithm uses historical data simulation as well as a GARCH model.

In the last few years, there have been a lot of interests in wireless ad-hoc networks as they have remarkable commercial and military applications. Such wireless networks have the benefit of avoiding a wired infrastructure. However, signal fading is a severe problem for wireless communications particularly for the multi-hop transmissions in the ad-hoc networks. Cooperative communication has been proposed as an effective way to improve the quality of wireless links. The key idea is to have multiple wireless devices at different locations cooperatively share their antenna resources and aid each other’s transmission. In this thesis, we develop effective algorithms for cooperative wireless ad-hoc networks, and the performance of cooperative communication is measured based on various criteria, such as cooperative region, power ratio and end-to-end performance. For example, the proposed interference subtraction and supplementary cooperation algorithms can significantly improve network throughput of a multi-hop routing. Comprehensive simulations are carried out for all the proposed algorithms and performance analysis, providing quantitative evidence and comparison over other schemes. In our view, the new cooperative communication algorithms proposed in this research enable wireless ad-hoc networks to improve radio unreliability and meet future application requirements of high-speed and high-quality services with high energy efficiency. The acquired new insights on the network performance of the proposed algorithms can also provide precise guidelines for efficient designs of practical and reliable communications systems. Hence these results will potentially have a broad impact across a range of related areas, including wireless communications, network protocols, radio transceiver design and information theory.

This thesis deals with the studies on the Cooperative Teleoperation Systems. The literature on cooperative teleoperation did not take into account
control architectures composed of pairs of wave-based bilateral teleoperators operating in
a shared environment. In this work The author two cooperative

Ch. 2 introduces a description of the two control architectures proposed and presents some
simulation results where the cooperative teleoperation systems evolve in free space and in
contact with a stiff wall.
In the Ch. 3 some experimental results which confirm the positive results of the control

In Ch. 4 the problem of defining proper tools and procedures for an analysis, and possibly a comparison, of the performances of cooperative teleoperation systems is addressed.
In particular, a novel generalization of criteria adopted for classical (i.e. one master-one slave) teleoperators is presented and illustrated on the basis of the force-position and the
position-position cooperative control schemes proposed in Ch. 2, both from a transparency

O surgimento de associações e cooperativas de catadores de material reciclável se constitui importante iniciativa, vez que comportam tanto melhorias financeiras, como a minimização da vulnerabilidade dos catadores. Esta pesquisa teve por objetivo analisar a vivência do cooperativismo e o empoderamento do cooperado. A pesquisa foi conduzida junto a cooperativa Ambiente localizada na região da Estrutural, Brasília-DF. A correlação entre a vivência do cooperativismo e o empoderamento do cooperado foi analisada do ponto de vista teórico e metodológico, e para isso empregou-se a estratégia de pesquisa de cunho exploratória e descritiva, utilizando-se entrevista e observação participante como técnicas de coleta de dados. Os resultados evidenciaram a existência de processos de empoderamento nos diferentes níveis estudados porém com limites. Tais trabalhadores têm buscado reconhecimento social, através das tentativas de tornarem visíveis as atividades de triagem e reciclagem dos resíduos e de se firmarem enquanto uma categoria ocupacional específica, por intermédio de sua organização política, o que vem a contribuir para seu empoderamento, individual e coletivamente. Contudo, existem limites quanto ao empoderamento individual, vez que os catadores se beneficiam das garantias de uma cooperativa, porém com restrições, por não ocorrer o atendimento a determinados princípios cooperativistas.
The emergence of associations and cooperatives of recyclable waste collectors constitute an important initiative, since they involve both financial improvements and minimizing the vulnerability of waste pickers. This research aimed to analyze the experience of cooperativism and the empowerment of the cooperative. The research was conducted together with the Environment cooperative located in the region of Estrutural, Brasília-DF. The correlation between the experience of cooperativism and the empowerment of the cooperative was analyzed from a theoretical and methodological perspective. For this purpose, the exploratory and descriptive research strategy was used by, using interview and participant observation as techniques for collecting data. The results indicated the existence of empowerment processes in the different levels studied but with limits. Such workers have sought social recognition, through attempts to make visible the activities of sorting and recycling of waste and to establish themselves as a specific occupational category, through their political organization, which contributes to their empowerment, individually and collectively. However, there are limits to individual empowerment, since the collectors benefit from the guarantees of a cooperative, but with restrictions, due to non-compliance with certain cooperative principles.

Texto completo da fonteResumo:
Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. In addition to reducing complexity and costs, increasing redundancy, and facilitating more timely decisions; distributed resource sharing regimes can decouple the individual subsystems. Decoupled subsystems could be desirable both because competing operators can be business-wise separated and because it allows new technologies to be added (removed) in a modular fashion. However, distributed regimes can also lead to “selfish” wireless nodes who only try to maximize their own performance. The first part of this dissertation studies if selfish nodes can make efficient use of wireless resources, using multiaccess and network layers as examples. The related problems are formulated as noncooperative games between nodes. To maintain tractability nodes are confined to simple strategies that neither account for future payoffs nor allow for coordination. Yet, it is demonstrated that selfish nodes can achieve comparable performance to traditional protocols. These results should be interpreted as an argument in favor of distributed regimes. The second part of this dissertation evaluates the effects of multi-provider network architectures where users can roam freely across all networks. From a supply side perspective the benefits are improved path gain statistics and the fact that different networks may have non-overlapping busy hours. Several network configurations are analyzed and it is shown that cooperation between symmetric providers can yield significant capacity gains for both downlink and uplink; even if the providers have nearly collocated sites. When the providers have different site densities the gains from cooperation are reduced and the provider with a sparse network always gains more from cooperating. This suggests that initially, voluntary cooperation may be limited to some special cases. Lastly, the architecture is analyzed in a context where the providers compete for users on a per session basis by offering access at different prices. Although such architectures currently only exist in a few special cases, they could emerge in domestic markets where the costs to switch and search for new networks are low. Based on a game theoretic formulation it is shown that a competitive market for wireless access can be advantageous for both users and providers. The results presented suggest that the advantages of cooperation of competing providers occur in more than just a few cases.QC 20100812

Texto completo da fonteResumo:
In this thesis, a distributed extremum seeking and cooperative control algorithm is designed for mobile agents to disperse
themselves optimally in maintaining communication quality and maximizing their coverage. The networked mobile agents
locally form a virtual multiple-input multiple-output (MIMO) communication system, and they cooperatively communicate
among them by using the decode and forward cooperative communication technique. The outage probability is used
as the measure of communication quality, and it can be estimated real-time. A general performance index balancing outage
probability and spatial dispersion is chosen for the overall system. The extremum seeking control approach
is used to estimate and optimize the value of the performance index, and the cooperative formation control is applied to
move the mobile agents to achieve the optimal solution by using only the locally-available information. Through the
integration of cooperative communication and cooperative control, network connectivity and coverage of the mobile agents
are much improved when compared to either non-cooperative communication approaches or other existing control results.
Analytical analysis is carried out to demonstrate the performance and robustness of the proposal methodology, and
simulation is done to illustrate its effectiveness.M.S.E.E.

Texto completo da fonteResumo:
This dissertation presents a case study of collaborative research through design with Floracaching, a gamified mobile application for citizen science biodiversity data collection. One contribution of this study is the articulation of collaborative research through design (CRtD), an approach that blends cooperative design approaches with the research through design methodology (RtD). Collaborative research through design is thus defined as an iterative process of cooperative design, where the collaborative vision of an ideal state is embedded in a design. Applying collaborative research through design with Floracaching illustrates how a number of cooperative techniques—especially contextual inquiry, prototyping, and focus groups—may be applied in a research through design setting. Four suggestions for collaborative research through design (recruit from a range of relevant backgrounds; take flexibility as a goal; enable independence and agency; and, choose techniques that support agreement or consensus) are offered to help others who wish to experiment with this new approach. Applying collaborative research through design to Floracaching yielded a new prototype of the application, accompanied by design annotations in the form of framing constructs for designing to support mobile, place-based citizen science activities. The prototype and framing constructs, which may inform other designers of similar citizen science technologies, are a second contribution of this research.

Context. Video games are a big entertainment industry. Many video games let players play against or together. Some video games also make it possible for players to play against or together with computer controlled players, called bots. Artificial Intelligence (AI) is used to create bots. Objectives. This thesis aims to implement cooperative behaviors between two bots and determine if the behaviors lead to an increase in win ratio. This means that the bots should be able to cooperate in certain situations, such as when they are attacked or when they are attacking. Methods. The bots win ratio will be tested with a series of quantitative experiments where in each experiment two teaming bots with cooperative behavior will play against two teaming bots without any cooperative behavior. The data will be analyzed with a t-test to determine if the data are statistical significant. Results and Conclusions. The results show that cooperative behavior can increase performance of two teaming Real Time Strategy bots against a non-cooperative team with two bots. However, the performance could either be increased or decreased depending on the situation. In three cases there were an increase in performance and in one the performance was decreased. In three cases there was no difference in performance. This suggests that more research is needed for these cases.

Texto completo da fonteResumo:
The main purpose of this study was to identify the major obstacles to cooperation as perceived by school library media specialists in the state of Mississippi and to determine if members of the Coastal Mississippi Library Cooperative (CMLC) believe that there are fewer obstacles to cooperation than do non-members. The secondary purpose was to evaluate the CMLC to some extent to determine if success was achieved through organization when defined by the variables, planning, governance, funding, communication, administration, and evaluation. The population of the study was all of the librarians (academic, public, school, and special) in the six-county area which comprises the CMLC, and a random sample of public school librarians throughout the remainder of the state. All of the school librarians were sent a questionnaire that requested their responses to statements of barriers to cooperation. All of the librarians in the CMLC region were sent a questionnaire to obtain their perceptions of participation in the CMLC. Pour librarians, members of the CMLC, were Interviewed to obtain information on the organizational factors of the CMLC. Data received from school library media specialists were submitted to various statistical tests. The Chi-Square statistic was used on the demographic portion of the questionnaire, which revealed that four of the variables and the dependent variable, membership in the CMLC, were significantly different. A t-test performed on the barriers to cooperation section produced no significant differences between the member and non-member responses. The perceptions of participation in the CMLC data revealed that there were differences among the four library systems (academic, public, school, and special) involved, but most of the respondents considered the CMLC to be successful. Data from the interview also revealed that the CMLC was successful in its organization. Due to the overall low response to the survey, the stated hypotheses could not be accepted; however, many of the findings and implications should be useful in helping to eliminate several obstacles to cooperation in Mississippi.
