No. of bitstreams: 1 Francisco Bianchi.pdf: 1658151 bytes, checksum: 0b1376dad8e2f37c261e6edead4044a2 (MD5) Previous issue date: 2008-05-29 / The present study proposes a model for conceptual and theoretical access to information and knowledge, with an emphasis on ownership and access to the tacit knowledge in organizations productive. The architecture of the model is based on the metaphor of the road maps that guide the individual to the sources of information and knowledge, previously mapped in the organization. In terms of technology, the model takes into account the strong support of information and communications technologies (ICTs), particularly those related to the recovery and presentation of information on environment network Intranet, making it comprehensive and easily accessible not only by specialists, but mostly by individuals with little or neither ability to use computers. Although the strong point of the proposed model is the present stage of ICTs, its main focus isn t the technology but the people who will interact with the model and take advantage of its features. Faced applicable, it is recognized the importance of motivation, both for individuals seeking information to satisfy their needs cognitive, as for the information of professionals responsible for the processes of management of information and knowledge in organizations, as critical factor for success of the proposed model. For theoretical validate of the model proposed in this study, looking up in the Information Science, Administration and Computer Science, important concepts on the management of information and knowledge, business organization and information technologies. This work is concluded presenting a theoretical and conceptual model for access to information and knowledge, supported by technology Intranet network. / O presente estudo prop?e um modelo conceitual e te?rico para acesso ? informa??o e conhecimento, com ?nfase na apropria??o e acesso ao conhecimento t?cito, em organiza??es produtivas. A arquitetura do modelo esta baseada na met?fora dos mapas rodovi?rios, que guiar? o indiv?duo at? as fontes de informa??o e conhecimento, previamente mapeadas na organiza??o. Em termos de tecnologias, o modelo leva em considera??o o forte apoio das tecnologias de informa??o e comunica??o (TICs), principalmente aquelas relacionadas com a recupera??o e apresenta??o da informa??o, em ambiente de rede Intranet, tornando-o abrangente e de f?cil acesso n?o somente por especialistas, mas principalmente por indiv?duos com pouca ou nenhuma habilidade de uso de computadores. Embora o ponto forte do modelo proposto seja o est?gio atual das TICs, seu foco principal n?o s?o as tecnologias, mas as pessoas que ir?o interagir com o modelo e se beneficiar das suas funcionalidades. Diante disso, reconhece-se a import?ncia da motiva??o, tanto dos indiv?duos que buscam informa??es para satisfazer suas necessidades cognitivas, quanto dos profissionais da informa??o respons?veis pelos processos de gest?o da informa??o e do conhecimento nas organiza??es, como sendo fator cr?tico de sucesso do modelo proposto. Para fundamenta??o te?rica do modelo proposto neste trabalho, buscam-se nas Ci?ncias da Informa??o, Administra??o e Computa??o, os conceitos importantes sobre gest?o da informa??o e do conhecimento, organiza??o empresarial e tecnologias da informa??o. Conclui-se este trabalho apresentando um modelo te?rico e conceitual para acesso ? informa??o e conhecimento, apoiado por tecnologias de rede Intranet.

No. of bitstreams: 1 Rodrigo Aquino de Carvalho.pdf: 1679875 bytes, checksum: fa32bdb2c592532c696f6356ca40494e (MD5) Previous issue date: 2009-02-27 / The Web became the main vehicle of the information storage and dissemination, but the information in this environment must be organized by efficient manner. The research objective was identify perspectives in the Semantic Web to the Information Science, through the literature mapping of basic proposals of this technology and of its development and through the analysis of the theses and dissertations about the subject presented to the Graduate Programs of Information Science in Brazil. Dialectical method with exploratory and descriptive approach and bibliographical technical procedures allied with bibliometrics and content analysis were applied. The following movements and relations were studied: - the origin of the Web to the actual status of the Semantic Web (qualitative change); - the actual Web and the Semantic Web (movement, qualitative change); - Information Science (through the literature review) and Semantic Web (relations); and Information Science (in theses and dissertations of the Brazil) and Semantic Web (relations). The movement of the current Web to the Semantic Web was significant, with objectives dedicated to make possible complex inferences about machines. Leaving the simplicity of the architecture of the current Web, the Semantic Web grew little, it didn't have significant qualitative movement. With relationship to Information Science, your architecture sustains a relationship. The field of Information Science, in what concerns to the literature of retrieval and representation of the information and representation of the knowledge presents resources that can collaborate for the development of the Semantic Web (as thesaurus, metadata etc.). Other point that favours that approach is the interdisciplinary relationship of the field with the Computational Science, with the Artificial Intelligence and with the Linguistics (Terminology). But it exists the need that the knowledge on the generated knowledge Information Science on the Semantic Web surpasses the limits of the proper field. / A Web se tornou o principal ve?culo de armazenamento e dissemina??o da informa??o, mas h? a necessidade de que a informa??o nesse ambiente seja tratada de forma eficiente. O objetivo da pesquisa ? buscar perspectivas na Web Sem?ntica para a Ci?ncia da Informa??o, atrav?s do mapeamento na literatura das propostas b?sicas dessa tecnologia e do desenvolvimento j? alcan?ado e tamb?m da an?lise das teses e disserta??es sobre o tema apresentado aos Programas de P?sgradua??o em Ci?ncia da Informa??o no Brasil. O m?todo utilizado foi o dial?tico, com abordagem explorat?ria e descritiva, o procedimento t?cnico foi o bibliogr?fico e as t?cnicas para a estrutura??o dos dados foram a bibliometria e a an?lise de conte?do. Foram estudados os seguintes movimentos e rela??es: - do surgimento da Web at? o estado atual da Web Sem?ntica (mudan?a qualitativa); - Web atual e Web Sem?ntica (movimento, mudan?a qualitativa); - Ci?ncia da Informa??o (atrav?s da revis?o de literatura) e Web sem?ntica (rela??es); e - Ci?ncia da Informa??o (em teses e disserta??es do Brasil) e Web Sem?ntica (rela??es). O movimento da Web atual ? Web Sem?ntica foi significativo, com objetivos voltados a possibilitar infer?ncias complexas por parte das m?quinas, mas deixando a simplicidade da arquitetura da Web atual, a Web Sem?ntica se desenvolveu pouco, n?o teve movimento qualitativo significativo. Quanto ? CI, sua arquitetura sustenta uma rela??o. A literatura da CI, no que diz respeito ? recupera??o e representa??o da informa??o e representa??o do conhecimento, possui recursos que podem colaborar para o desenvolvimento da Web Sem?ntica (como os tesauros, os metadados etc,). Outro ponto que favorece essa aproxima??o ? a rela??o interdisciplinar da ?rea com a Ci?ncia da Computa??o, com a Intelig?ncia Artificial e com a Ling??stica (Terminologia). Mas existe a necessidade de que o conhecimento gerado na CI, sobre a Web Sem?ntica ultrapasse os limites da pr?pria ?rea.

The present study encompasses the new ERP configuration, dedicated to support companies in its front end operations and value chain integration, so called ERPII model, and investigates the relationship with the Dynamic Capabilities during the post-implementation phase. In order to ac-complish this objectives, a conceptual Framework is developed, to articulate the construct variables with the level of market turbulence. Furthermore, a quantitative field research is executed, based on a survey, and the research results are interpreted under the Framework perspective, where the results are validated through statistical tests such as Spearman correlation, Mann-Withney and Kruskal-Wallis, in order to obtain an explicative analysis of the Dynamic Capabilities role in the sustenance of ERPII. The results, evidenced Dynamic Capabilities in all presuppositions articulated by the Framework, with positive impacts in reconfiguration of routines responsible for ERPII sustenance and its organizational performance contribution. In this sense, the major effects were identified in sensing and seizing of market opportunities focused on evolving ERPII, management initiatives to encourage tacit and explicit learning processes, coordination of ERPII quality and performance metrics, and level of uncertain of business market related to ERPII context. / Os anos de 1990 apresentaram um crescimento na ado????o dos sistemas de gest??o empresarial (ERPs) pelas organiza????es, e o tema foi estudado em um grande n??me-ro de publica????es acad??micas, que apontaram o mesmo como um impulsionador da obten????o da vantagem competitiva e desempenho empresarial. A presente disserta-????o aborda a configura????o contempor??nea dos sistemas ERPs, dedicada a suportar as empresas em suas opera????es de linha de frente e integra????o com a cadeia de valor, dentro do modelo conceitual chamado ERPII, e analisa suas rela????es com as Capacidades Din??micas em sua fase de p??s-implementa????o. Para tanto, um Fra-mework conceitual ?? proposto, com o objetivo de articular as vari??veis relativas aos constructos, agregando-as a indicadores concernentes ao n??vel de incerteza do am-biente. Em continuidade, o trabalho apresenta uma pesquisa de campo, executada por meio de um instrumento de pesquisa de natureza quantitativa. Por fim, sob a ??ti-ca do Framework desenvolvido, os resultados da pesquisa s??o validados estatisti-camente por meio de testes de correla????o de Spearman, Mann-Withney e Kruskal-Wallis, visando obter uma an??lise explicativa do papel das Capacidades Din??micas na sustenta????o do ERPII. Como resultados, observou-se a presen??a das Capacida-des Din??micas em todos os pressupostos articulados por meio do Framework, com impacto positivo na reconfigura????o de rotinas respons??veis pela sustenta????o do ERPII e consequente contribui????o para o desempenho organizacional. Nesse senti-do, os fatores que exerceram maior influ??ncia foram os relacionados a mecanismos de prospec????o e tratamento de oportunidades e atualiza????es do ERPII, seguidos por a????es gerenciais de incentivo ?? aprendizagem t??cita e expl??cita, coordena????o de in-dicadores de qualidade e desempenho, e n??vel de dinamicidade do mercado de ne-g??cios no contexto do ERPII.
