A comunicação interna numa organização pública

The present study compose an analysis on the process of internal communication at a public organization, built on the survey data originary of administrative conduct, observation on the cultural model of the organization and how the interdepartmental and interpersonal relations shows up. The research, exploratory descriptive kind, had theoretical basis on two knowledge areas Administrative Science and Social Communication and was developed at Instituto do Desenvolvimento Econômico e Meio Ambiente IDEMA, in Rio Grande do Norte. During data collection, were conducted spontaneous and semi structured interviews with directors and coordinators, besides the application of directed questionnaire to functionaries in two unites of the institution. Through the analysis and interpretation of the data, we came to the conclusion that the process of internal communication at a public organization fall in with same challenges of private organizations, but with peculiarities that attracts the scientific look specially, in concern of the attitude assumed by the administrators in the conduction of communication functions inside the organization, the profile of social actor and the communication channels used. Although the organizational communication represents more and more a strategic function, as an administration tool, the point that research gets to shows that in public organizations the communication refrains from administrative purpose and with the major objective of giving publicity to the institutional acts and actions

Testicular structure and spermatogenesis of Amazonian freshwater cururu stingray Potamotrygon cf. histrix

The cururu stingray Potamotrygon cf. histrix, a new and endemic Amazonian freshwater species, presents appropriate characteristics for fish keeping and is exploited from its natural environment. The present study identified the testicular structure and spermatogenesis of this species. Gonads from adult male specimens were dissected, fixed and processed for histological analysis. The testes were of testicular/epigonial type. The presence of germinal papillae was observed in the upper portion of organ with primordial germ cells and Sertoli cell precursors. The testis was lobular with zonal organization and cystic gametogenesis, with the occurrence of spermatoblasts. The Sertoli cells underwent morphological modifications over the course of gamete formation. The spermatozoids had long heads and were spiraled on their own axis. Information on the reproductive biology will serve as basis for studies on the reproduction and phylogeny of this peculiar group of cartilaginous fish.

Data information system to promote the organization data of collections - modeling considerations by the Unified Modelign Language (UML)

Pode-se afirmar que a evolução tecnológica (desenvolvimento de novos instrumentos de medição como, softwares, satélites e computadores, bem como, o barateamento das mídias de armazenamento) permite às Organizações produzirem e adquirirem grande quantidade de dados em curto espaço de tempo. Devido ao volume de dados, Organizações de pesquisa se tornam potencialmente vulneráveis aos impactos da explosão de informações. Uma solução adotada por algumas Organizações é a utilização de ferramentas de sistemas de informação para auxiliar na documentação, recuperação e análise dos dados. No âmbito científico, essas ferramentas são desenvolvidas para armazenar diferentes padrões de metadados (dados sobre dados). Durante o processo de desenvolvimento destas ferramentas, destaca-se a adoção de padrões como a Linguagem Unificada de Modelagem (UML, do Inglês Unified Modeling Language), cujos diagramas auxiliam na modelagem de diferentes aspectos do software. O objetivo deste estudo é apresentar uma ferramenta de sistemas de informação para auxiliar na documentação dos dados das Organizações por meio de metadados e destacar o processo de modelagem de software, por meio da UML. Será abordado o Padrão de Metadados Digitais Geoespaciais, amplamente utilizado na catalogação de dados por Organizações científicas de todo mundo, e os diagramas dinâmicos e estáticos da UML como casos de uso, sequências e classes. O desenvolvimento das ferramentas de sistemas de informação pode ser uma forma de promover a organização e a divulgação de dados científicos. No entanto, o processo de modelagem requer especial atenção para o desenvolvimento de interfaces que estimularão o uso das ferramentas de sistemas de informação.

A escola como lócus de formação docente: uma gestão bem-sucedida

O trabalho focaliza a escola como lócus de formação. Analisa o contexto de uma escola de sucesso da rede municipal de Campo Grande, Estado do Mato Grosso do Sul, descrevendo-o em suas características. Entre estas, destaca a gestão e o clima escolar. Para tanto, entrevista professores e gestores sobre a organização da escola, o estilo de gestão, bem como sobre os seus efeitos no trabalho do professor e no desempenho dos alunos. O exame das entrevistas permitiu construir algumas categorias que definem o ethos da instituição: o porte pequeno, o trabalho em equipe, as relações democráticas e o compromisso com os alunos. A análise destaca o profissionalismo da gestão e da sua visão prospectiva sobre a tarefa educativa, estimulando os professores a enfrentarem os desafios e compartilhando com eles as formas de superar as dificuldades. O estudo aponta a importância da rede de relações que se estabelece no contexto da escola como forma de socialização da profissão, construção da identidade docente e espaço de formação de professores a partir da prática.

Interaction of pathogenic fungi with host cells: Molecular and cellular approaches

This review provides an overview of several molecular and cellular approaches that are likely to supply insights into the host-fungus interaction. Fungi present intra- and/or extracellular host-parasite interfaces, the parasitism phenomenon being dependent on complementary surface molecules. The entry of the pathogen into the host cell is initiated by the fungus adhering to the cell surface, which generates an uptake signal that may induce its cytoplasmatic internalization. Furthermore, microbial pathogens use a variety of their surface molecules to bind to host extracellular matrix (ECM) components to establish an effective infection. on the other hand, integrins mediate the tight adhesion of cells to the ECM at sites referred to as focal adhesions and also play a role in cell signaling. The phosphorylation process is an important mechanism of cell signaling and regulation; it has been implicated recently in defense strategies against a variety of pathogens that alter host-signaling pathways in order to facilitate their invasion and survival within host cells. The study of signal transduction pathways in virulent fungi is especially important in view of their putative role in the regulation of pathogenicity. This review discusses fungal adherence, changes in cytoskeletal organization and signal transduction in relation to host-fungus interaction. (c) 2005 Federation of European Microbiological Societies.

Roots, leaves and scapes anatomy of species of Paepalanthus subgenus Platycaulon (Eriocaulaceae)

The anatomical features of roots, leaves and scapes of the subgenus Platycaulon, genus Paepalanthus (Eriocaulaceae) that grow in the Brasilian rupestrian fields of Serra do Cipo - MG - Brazil were studied. The following main anatomical features were found: epidermis cells of varied thicknesses, chlorenchyma with compact or spread organization and leaf margin shape in the leaves; the scapes with continuous or discontinuous endodermis, divided or undivided pericycle, vascular bundles absent in the cortex and in the pith. These anatomical characteristics of the leaves and scapes occur in different species and can be used to separate them into Divise or Conferti sections. It was possible to confirm the proposed taxonomy based only on the morphological characteristics. Other anatomical features such as: presence or absence of air in the cortex roots and hypodermis which originate water parenchyma reserves in the mesophyll, can be an adaptative response that plants towards produce the environmental factors in this ecosystem.
