A relação entre confiança interpessoal e compartilhamento de conhecimento tácito

Empresas de negócios, que são constantemente pressionados por inovação, têm na criação de conhecimento organizacional a base para a estratégia de sobrevivência. Muito desse conhecimento acumulado é tácito, encarnado em indivíduos e incorporado pela organização, e que é de difícil articulação. A necessária justificativa de um novo conhecimento torna a sua criação um processo muito frágil. Indivíduos podem sentir-se ameaçados em compartilhar insights, intuição, novas ideias, know-how, habilidades específicas, diante de devastadores mecanismos de controle social como ridículo, difamação e opróbrio, ou pela possibilidade de mau uso de um conhecimento útil e valioso. Por outro lado, com a criança logo ao nascer, e derivado do narcisismo primário, emerge a confiança básica que acompanha o indivíduo ao longo de sua existência, e que, portanto, pode levá-lo a compartilhar seus achados. Esta pesquisa, um ensaio teórico, explorou a relação entre a confiança e compartilhamento de conhecimento tácito nas organizações. Com abordagem multidisciplinar, aderente ao pensamento complexo, incorporou referenciais teóricos advindos de trabalhos de neo-schumpeterianos (Teoria Evolucionária), da sociologia e da psicologia. O percurso metodológico contemplou a busca de artigos em base de dados, leitura de resumos de artigos, busca de autores consagrados na literatura, consulta de autores referenciados nos artigos, leitura e análise de trabalhos selecionados. Mediante análise de conteúdo, que busca identificar o que está sendo dito a respeito do tema, foram criadas as seguintes categorias de análise: inovação, poder, teoria de criação de conhecimento organizacional e confiança humana. Cada uma dessas categorias compôs um capítulo desta dissertação. Embora a escassez de pesquisas empíricas relacionadas ao tema, a análise de conteúdo dos artigos examinados permitiram concluir que a confiança interpessoal mantém relação de poder simétrico entre indivíduos e assim é capaz de acessar o conhecimento tácito enraizado na mente de indivíduos. Dessa forma, com a pesquisa aqui apresentada, espera-se ter contribuído para a literatura e práticas organizacionais relacionadas à gestão de conhecimento. Por fim, foram relatadas limitações no trabalho e sugestões para futuras pesquisas.

Adoção de governo eletrônico no Brasil: a perspectiva do usuário do Programa Nota Fiscal Paulista

A intensa utilização da tecnologia da informação (TI) por todos os setores disseminou-se também na Administração Pública. A utilização da TI aliada à internet como ferramenta de gestão pública é denominada governo eletrônico e tem como objetivos qualificar melhor a prestação dos serviços e possibilitar aos cidadãos uma participação mais efetiva no processo político. O presente estudo buscou investigar o contexto do governo eletrônico no Brasil e apresenta um modelo de adoção baseado numa iniciativa de informatização de mecanismos de controle fiscal do Estado de São Paulo. O objetivo geral da tese foi estudar quais são os elementos que influenciam a utilização do governo eletrônico no Brasil, por meio de um estudo no programa Nota Fiscal Paulista (NFP). A metodologia envolveu técnicas do método qualitativo, pelo uso de opiniões de especialistas, associadas a procedimentos do método quantitativo, por meio de um survey aplicado em 715 usuários da NFP. A análise utilizou modelagem por equações estruturais. Os resultados contribuem para as pesquisas em TI, apresentando um modelo que reforça e amplia os estudos anteriores sobre adoção tecnológica e os estudos de governo eletrônico, acrescentando um modelo em um novo contexto ainda pouco explorado. No caso da NFP, os fatores testados e que influenciam no processo de adoção são: Benefício Percebido, Facilidade de Uso Percebida, Influências Sociais, Segurança Percebida, Confiança e Hábito. Em termos práticos, a pesquisa auxilia na compreensão da participação e do envolvimento dos cidadãos na fase atual de desenvolvimento de governo eletrônico no Brasil. Com melhor esclarecimento da influência dessa tecnologia na vida pessoal e profissional dos usuários, é possível elevar a qualidade da prestação dos serviços para atender às demandas da sociedade. Isto posto, auxilia também na implantação mais rápida do programa em outros contextos administrativos para o governo eletrônico, gerando informações úteis para os principais pontos a se considerar para ampliar a adesão dos cidadãos e ter mais chance de sucesso na implantação.

Fragilidades dos mecanismos de controle das organizações sociais de saúde no município do Rio de Janeiro

Nosso problema de pesquisa neste trabalho é a avaliação do funcionamento dos principais mecanismos de controle das organizações sociais de saúde, no caso específico do Município do Rio de Janeiro. As reiteradas denúncias de irregularidades e ilegalidades pelo Tribunal de Contas do Município do Rio de Janeiro e pelo Ministério Público do Estado do Rio de Janeiro levantaram dúvidas acerca da adequação dos processos de monitoramento, fiscalização e controle dessas entidades. Disto decorre nosso objetivo central de pesquisa, que é identificar as fragilidades do novo modelo de gestão por organizações sociais de saúde, no caso da cidade do Rio de Janeiro. Para isso, foram analisados: o arcabouço jurídico-normativo do modelo local, a partir de análise comparativa da legislação municipal que regulamenta seu funcionamento (Lei 5.026/09) e sua contraparte federal (Lei 9.637/98); indicadores de saúde que mensurassem o desempenho das OSS; todas as inspeções realizadas pelo TCM-RJ até o fim de 2015; e o conjunto de recomendações enviado pelo MP-ERJ para a Prefeitura após deflagração da Operação Ilha Fiscal, que acarretou a desqualificação da OS BIOTECH e a prisão de seus dirigentes, acusados de desviar mais de R$48 milhões em recursos públicos. Ao final, constatouse que as fragilidades da legislação municipal e dos decretos executivos que regulamentam a atuação das OSS no MRJ não permitem o exercício efetivo do comando da parceria, em afronta, portanto, ao dispositivo constitucional que determina que a atuação de entidades privadas no âmbito do SUS pode se dar apenas de modo complementar. Ademais, verificou-se total inadequação da estrutura de controle pela Prefeitura, cuja principal consequência foi tornar o modelo de reforma gerencialista em um modelo que incentiva o comportamento patrimonialista no âmbito da saúde pública, uma vez que o controle de meios é absolutamente negligenciado.

Vigilância eletrônica no trabalho bancário: do controle consentido ao totalitarismo corporativo

This dissertation addresses the electronic surveillance theme in the banking context. The research that originated it, which was held in an organization called for the fiction name Banco Total, started from the following driving question: How do workers at a bank perceive electronic surveillance at their process of work? The research s main objective was to comprehend how workers perceive electronic surveillance at their process of work. The study adopted an interdisciplinary perspective, having Management as the original field, establishing a dialogue with others disciplines, like Philosophy and Sociology. About its methodology, it s a qualitative research that addressed its object in oral (interviews with live history elements) way. . Ten individuals were interviewed. The analytical process utilized the hermeneutical-dialectics technique.. From the analyses (hermeneutics) of the data, the following themes have emerged: (i) Acquiescence ; (ii) Monitoring; (iii) Time and Motion; (iv) Fear; (v) Interdiction; and (vi) Resistance . From the discussion (dialectic) of the results, this work presents three synthetic propositions that culminate in the following dimensions (i) control; (ii) acquiescence; (iii) corporative totalitarianism. It can be concluded that electronic surveillance is one mechanism of control emerged from the apply of technology at Total Bank; that information technology has been improving the control mechanisms of management theories; and that the imbrications between management and material technology control mechanisms at a context where there is acquiescence by workers contribute for the emergency of corporative totalitarianism components

Alterações no metabolismo de zinco relacionadas ao envelhecimento

Although many studies point to alterations in the organic concentrations of zinc in elderly patients, the mechanisms by which aging might cause changes in the metabolism of this nutrient remain unclear. Thus, we assessed the changes in plasma zinc, Zinc Binding Capacity to Plasma Protein (ZnBCPP) and Saturation Index (SI), comparing elderly individuals and young adults. The zinc analyses were performed by atomic absorption spectrophotometry. A statistically significant difference (p < 0.001) was found between the two groups, in relation to plasma zinc and SI, but the ZnBCPP did not differ between the younger and older subjects. In agreement with this result, it was shown in the young group that 76% (R2 = 0.760) of the ZnBCPP variations are explained by the variations in plasma zinc and SI. In the elderly group this measure decreased to 30.5% (R2 = 0.305). We conclude, therefore, that aging may be a factor associated to changes in control mechanisms and in zinc homeostasis, and could even alter ZnBCPP response patterns and other zinc-related indicators of nutritional status.

Entre desvios e normas: infração juvenil feminina na cidade de Natal - RN

This paper presents some reflections on the social world of young female transgression. The context corresponds to those ones that obey social and educational measures in The Padre João Maria Education Centre (CEDUC), in Natal- RN. This behavior, according to the Statute of Children and Young (ECA, 1990), is defined as "conduct described as crime or misdemeanor." Our goal is to discuss aspects of the contexts in which young women are interacting with the universe of total institutional control mechanisms. Through the socio-anthropological analysis of the ethnographic practice in field research, it was necessary to question the concept of misuse engaged in the practice of penalties awarded to young women in the context of private freedom. So was built a frame relating the representations of the relations of gender, generation, the practice of violence and crime from the look on CEDUC/ Padre João Maria Education Centre

Desenvolvimento de um ressoador retangular de fenda com múltiplas camadas de substrato e com utilização de material PBG para sistema de comunicação sem fio

In the globalized world modern telecommunications have assumed key role within the company, causing a large increase in demand for the wireless technology of communication, which has been happening in recent years have greatly increased the number of applications using this technology. Due to this demand, new materials are developed to enable new control mechanisms and propagation of electromagnetic waves. The research to develop new technologies for wireless communication presents a multidisciplinary study that covers from the new geometries for passive antennas, active up to the development of materials for devices that improve the performance at the frequency range of operation. Recently, planar antennas have attracted interest due to their characteristics and advantages when compared with other types of antennas. In the area of mobile communications the need for antennas of this type has become increasingly used, due to intensive development, which needs to operate in multifrequency antennas and broadband. The microstrip antennas have narrow bandwidth due to the dielectric losses generated by irradiation. Another limitation is the degradation of the radiation pattern due to the generation of surface waves in the substrate. Some techniques have been developed to minimize this limitation of bandwidth, such as the study of type materials PBG - Photonic Band Gap, to form the dielectric material. This work has as main objective the development project of a slot resonator with multiple layers and use the type PBG substrate, which carried out the optimization from the numerical analysis and then designed the device initially proposed for the band electromagnetic spectrum between 3-9 GHz, which basically includes the band S to X. Was used as the dielectric material RT/Duroid 5870 and RT/Duroid 6010.LM where both are laminated ceramic-filled PTFE dielectric constants 2.33 and 10.2, respectively. Through an experimental investigation was conducted an analysis of the simulated versus measured by observing the behavior of the radiation characteristics from the height variation of the dielectric multilayer substrates. We also used the LTT method resonators structures rectangular slot with multiple layers of material photonic PBG in order to obtain the resonance frequency and the entire theory involving the electromagnetic parameters of the structure under consideration. xviii The analysis developed in this work was performed using the method LTT - Transverse Transmission Line, in the field of Fourier transform that uses a component propagating in the y direction (transverse to the real direction of propagation z), thus treating the general equations of the fields electric and magnetic and function. The PBG theory is applied to obtain the relative permittivity of the polarizations for the sep photonic composite substrates material. The results are obtained with the commercial software Ansoft HFSS, used for accurate analysis of the electromagnetic behavior of the planar device under study through the Finite Element Method (FEM). Numerical computational results are presented in graphical form in two and three dimensions, playing in the parameters of return loss, frequency of radiation and radiation diagram, radiation efficiency and surface current for the device under study, and have as substrates, photonic materials and had been simulated in an appropriate computational tool. With respect to the planar device design study are presented in the simulated and measured results that show good agreement with measurements made. These results are mainly in the identification of resonance modes and determining the characteristics of the designed device, such as resonant frequency, return loss and radiation pattern

A gestão do Sistema Único de Assistência Social em Currais Novos (RN)

The present paper analyses the social assistance management in small cities, starting from the reality of Currais Novos City. Its main objective is to analyse the management of this politic in the context of the Nacional Sistem of Social Assistance (SUAS) through the management instruments materialized in the city: Social Assistance Plan, Budget, Management Report, Information Management, Monitorizing and Evaluation. It reveals a discrepancy between the instruments purpose and their concretude, and it identifies the main challenges in order to make them real, revealing the contradictions of such politic, through which the advances relate with the retrocesses. It remarks, in this context, the debate about Public Management and some aspects of the trajetory of the Social Assistance management in the brazilian context and the configurations of (SUAS) and of the politics in Currais Novos city. Such path allows us to identify the feebleness in the city ways to adopt the (SUAS) criteria, which is much more effective in burocratic aspects than in the change of the Social Assistance conception and in the effective incorporation of the (SUAS) principles and guidelines. Thus, problems are identified in what concerns to the important aspects for its effectivation, with the human resources, financing and social control mechanisms. It makes possible to reafirm the importance of the analysed management instruments for the effectivation of one participative and democratic management, as well as the urgency of its materialization as one of the important ellements for this politic to happen as a right and to make a stop to the unconformities between the (SUAS) determinations and its materialization

Imbalance of IL-2, IFN-gamma and IL-10 secretion in the immunosuppression associated with human paracoccidioidomycosis

Patients with paracoccidioidomycosis (PCM) display a certain degree of immunecompromise characterized by lymphocyte hyporesponsiveness to the main Paracoccidioides brasiliensis antigen (gp43). To determine whether cytokines are involved in this state, we evaluated the secretion of IL-2, IL-10 and IFN-gamma by peripheral blood mononuclear cells (PBMC) from patients with the acute (AF) and chronic (CF) forms of PCM and from healthy, P. brasiliensis-sensitized subjects. gp43-stimulated PBMC from healthy subjects produced substantial amounts of IL-2, IFN-gamma and IL-10, whereas PBMC from AF and CF patients produced low levels of IL-2 and IFN-gamma but substantial amounts of IL-10, Phytohaemagglutinin-induced cytokine secretion was comparable among AF and CF patients and healthy subjects, suggesting integrity of non-specific cellular immune mechanisms in PCM. gp43-pulsed adherent cells, but not non-adherent cells, mere the main source of IL-10, Moreover, IL-2 and IFN-gamma secretion correlated inversely with the amount of specific antibodies produced by patients and healthy subjects. Our results suggest that the imbalance in cytokine production of patients with PCM plays a role in the gp43-hyporesponsiveness and the marked (non-protective) antibody production of these patients.

Mecanismos de ação e controle da digestão de proteínas e peptídios em humanos

This review aims to report the major control mechanisms of protein and peptides digestion of special interest in human patients. Regarding protein assimilation its digestive process begins at the stomach with some not so indispensable actions comparatively to those of duodenal/jejunal lumen. However even the intestine processes are partially under gastric secretion control. Proteolytic enzyme activities are related to protein structure and amino acid constituents, tertiary and quartenary structures need HCl - denaturation prior to enzymatic hydrolysis. Thereafter the exopeptidases are guided by either NH 2 (aminopeptidases) or COOH (carboxypeptidases) terminals of the molecule while endopeptidases are oriented by the specific amino acids constituents of the peptide. Both dietary and luminal secreted proteins and polypeptides undergo to either limited or complete proteolysis resulting basic or neutral free-amino acids (40%) or dioctapeptides. The brush border peptidases continue to degrade oligopeptide to di-tripeptides and neutral free-amino acids. Some peptides are uptaked by the enterocytes whose cytosolic peptidases complete the hydrolysis. Hence the digestive products flowing in the portal vein are mainly free-amino acids from either luminal or cytosolic hydrolysis and some di-tripeptides intactly absorbed. Both mechanical and chemical processes of digestion are under neural (vagal), neuroendocrinal(acetilcholine),endocrinal(gastrin, secretin and cholecystokinin) or paracrinal (histamine) controls. The gastric phase (hydrochloric acid and pepsinogen secretions) is activated by gastrin, histamine and acetilcholine which respond to both dietary-amino acids (tryptophan and phenylalanine) and mechanic distention of stomach. The pancreatic secretion is stimulated by either cephalic or gastric phases and has influence on the intestinal phase of digestion. The intestinal types of cells S and I release secretin and cholecystokinin respectively in response of acid quimo (cells S) or amino acids and peptides (cells I) in the lumen. Secretin stimulates the releasing of water, bicarbonate and enteropeptidases whereas cholecystokinin acts on pancreatic enzymes.

A importância das informações aferentes podais para o controle postural

Introduction. The postural control involves a complex mechanism for connecting the afferent and efferent pathways and their integration into the central nervous system (CNS). Three systems are responsible to obtain outside information: visual, vestibular and sensory. Recent studies have shown that among such systems, the CNS shows a greater predilection for sensory information to postural control. Objective. Given this, the review proposes to discuss the feet sensory information importance and its reflection in postural control mechanisms. Method. For this reason, a literature search was carried out by PubMed and Bireme libraries, and papers of the last five years were selected. Specific books were also used. Discussion. Studies were separated into topics on sensory information integration to neuro-motor answer, postural feed-forward adjustments recruitment mechanisms; neuro-muscular coordination and synergy responses and the musculoskeletal tissues role. Conclusion. Despite has been found a large number of studies, the real mechanism that the CNS uses to filter, integrate and process the sensory information and select the appropriate motor response, be it for the movement or posture for the stabilization remains obscure.

Morphometry and expression of MyoD and Myogenin in white and red skeletal muscles of juvenile fish Colossoma macropomum (Cuvier 1818)

Colossoma macropomum, also known as tambaqui, is an economically important fish species, and interesting new studies have been published with the aim of improving the growth of this fish. In this work, we describe the morphometric characteristics, as well as the mRNA and protein expression levels of two myogenic regulatory factors (MRFs)-myod/MyoD and myogenin/Myogenin-in the white and red muscle types of tambaqui. A high proportion of white and red muscle fibers with large diameters suggest a hypertrophic growth process in the skeletal muscle during juvenile stages. Comparisons between muscle types showed that, in red muscle, myogenin transcript levels were significantly higher than those of myod. In contrast, MyoD protein levels were significantly higher than those of Myogenin in red muscle. These results suggest that in red and white muscles of juvenile tambaqui, independent post-transcriptional mechanisms for regulating MyoD and Myogenin expression may exist, which could be differentially activated during muscle growth. Furthermore, these data also suggest that specific control mechanisms may regulate distinct muscle phenotypes. © 2013 The Royal Swedish Academy of Sciences.
