A transição do século XX para o século XXI trouxe consigo uma série de mudanças, em especial às organizações, que vivenciaram evoluções de ordem tecnológica impactantes em sua estrutura administrativa e econômica. As agências de publicidade, apesar de terem um enfoque voltado ao aspecto criativo, não deixam de ser organizações, e assim como as demais também vivenciam este ciclo de mudanças, que aparenta ser ininterrupto. A importância do planejamento estratégico e financeiro e do atendimento integrado aos clientes proporcionou às agências novas perspectivas de funcionamento, e nelas enquadram-se as fusões/aquisições. Agências internacionais optaram por participar do mercado publicitário brasileiro através de fusões/aquisições; estas ocorreram com agências de bastante expressão no mercado internacional, mas também com agências menos conhecidas, mas que demonstraram a realização de bons trabalhos no setor. Através deste estudo realizou-se uma análise a respeito do mercado de fusões e aquisições de agências de publicidade, em especial, sob a perspectiva financeira. Através da base de dados lançada no Software SPSS foi aplicado o Teste T. Constatou-se que as agências de publicidade no Brasil entre 1999 a 2009 não apresentaram diferenças de média em relação ao faturamento, independente de terem passado ou não pelo processo de fusão/aquisição. Este crescimento pouco representativo demonstra que as fusões/aquisições tendem a ocorrer por diversos motivos e não se restringem exclusivamente ao aspecto financeiro, a perspectiva de bom atendimento ao cliente, visando o planejamento estratégico no âmbito publicitário, tende a ser um deles.

The Acquisition Food Program (Programa de Aquisição de Alimentos – PAA) is one of the governmental public politics proposed, in the year of 2003, that has the focus in the family-run farm in Brazil. This Program has as objectives: commercialize the familyrun farm products, bought by the government agencies; to encourage production, and promoting actions that improve quality food of people facing starving risk. This Program has been working, to some extent, as complement to the Program of family-run farm Enhancement (PRONAF). The present study has as its focus to analyse the social territorials changes observed in the state of Rio Grande do Norte, as a result of the PAA implementation. In this sense, it was promoted a discussion between territory and rules. I this work, public politics are understood as rules. This procedure was important in order to understand how the rules have influenced territorial changes, creating new social and territorial relations. In the research process was used scientific and institutional texts on the subject. It was applied a quiz with 97 PAA’s supplying farmers, and interviews were done with the Program managers in Federal (MDA), State (CONAB and EMATER) and municipal (local office of EMATER and Departments of Agriculture) levels. Social public politics were also analyzed with the aim of understand the context where PAA is situated in relation with the public politics directed to familyrun farm as a whole since 1980, within new Brazilian democratization process. With the information collected in the field, plus the secondary data, maps, charts, tables and cartograms were made. With all of this, a socio-economical profile of the family-run farm in the Rio Grande do Norte was traced, as well as the included in this research. Before this picture, we concluded that PAA indeed represents a forward in public politics directed to family-run farm. However, in spite of the importance of the Program for the family-run farmers to come of age, but in order to the rural and family-run farm reality in the Rio Grande do Norte come to present meaningful changes much still remain to be done.

In the oil prospection research seismic data are usually irregular and sparsely sampled along the spatial coordinates due to obstacles in placement of geophones. Fourier methods provide a way to make the regularization of seismic data which are efficient if the input data is sampled on a regular grid. However, when these methods are applied to a set of irregularly sampled data, the orthogonality among the Fourier components is broken and the energy of a Fourier component may "leak" to other components, a phenomenon called "spectral leakage". The objective of this research is to study the spectral representation of irregularly sampled data method. In particular, it will be presented the basic structure of representation of the NDFT (nonuniform discrete Fourier transform), study their properties and demonstrate its potential in the processing of the seismic signal. In this way we study the FFT (fast Fourier transform) and the NFFT (nonuniform fast Fourier transform) which rapidly calculate the DFT (discrete Fourier transform) and NDFT. We compare the recovery of the signal using the FFT, DFT and NFFT. We approach the interpolation of seismic trace using the ALFT (antileakage Fourier transform) to overcome the problem of spectral leakage caused by uneven sampling. Applications to synthetic and real data showed that ALFT method works well on complex geology seismic data and suffers little with irregular spatial sampling of the data and edge effects, in addition it is robust and stable with noisy data. However, it is not as efficient as the FFT and its reconstruction is not as good in the case of irregular filling with large holes in the acquisition.

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies.

In this work, a platform to the conditioning, digitizing, visualization and recording of the EMG signals was developed. After the acquisition, the analysis can be done by signal processing techniques. The platform consists of two modules witch acquire electromyography (EMG) signals by surface electrodes, limit the interest frequency band, filter the power grid interference and digitalize the signals by the analogue-to- digital converter of the modules microcontroller. Thereby, the data are sent to the computer by the USB interface by the HID specification, displayed in real-time in graphical form and stored in files. As processing resources was implemented the operations of signal absolute value, the determination of effective value (RMS), Fourier analysis, digital filter (IIR) and the adaptive filter. Platform initial tests were performed with signal of lower and upper limbs with the aim to compare the EMG signal laterality. The open platform is intended to educational activities and academic research, allowing the addition of other processing methods that the researcher want to evaluate or other required analysis.

Na sociedade moderna, constata-se que os indivíduos multilingues compreendem e falam várias línguas e que essa proficiência tem despertado, ao longo de várias décadas, a curiosidade de numerosos especialistas no assunto (neurolinguistas, psicolinguistas). Sobre este assunto, Dijkstra (2003:11) preconiza que os falantes multilingues devem ter armazenado um vasto número de palavras no seu léxico mental no qual parece ser difícil recuperar uma palavra. Neste contexto, o presente trabalho, que se enquadra no Mestrado em Português Língua Não Materna, oferece uma revisão da literatura sobre o conhecimento neurolinguístico e psicolinguístico da aquisição multilingue do léxico em sujeitos bi / multilingues ; tendo como ponto nevrálgico o controlo inibitório e o acesso lexical. No decorrer desta pesquisa, a qual pôde contar com a participação de trinta e três informantes falantes de português europeu (3 monolingues, 3 bilingues, 5 trilingues e 22 multilingues), procurou-se averiguar se os informantes bi / multilingues seriam mais rápidos e precisos do que os monolingues, aquando da realização de tarefas trilingues de nomeação oral de imagens e de decisão lexical. A investigação realizada fornece dados para uma reflexão sobre o modo como falantes com estas particularidades acedem ao (s) seu (s) reportório (s) linguístico (s), bem como sobre a forma como exercem o controlo inibitório sobre o seu vasto campo linguístico.

Os fluxos migratórios das últimas décadas têm contribuído para que as comunidades de falantes de português se estabeleçam um pouco por todo o mundo, nomeadamente, nos países escandinavos. Um desses países de acolhimento, a Finlândia, tem desenvolvido esforços para a integração dos imigrantes que aí se estabelecem, designadamente, através da promoção de políticas de língua, que visam o ensino da língua de herança aos alunos em idade escolar. Tem sido neste contexto que as pequenas comunidades lusófonas, a viverem no país, têm podido facultar aos filhos, imigrantes de primeira e segunda gerações, acesso ao ensino formal da sua língua de herança, o português. Os sujeitos da nossa amostra fazem parte de uma dessas pequenas comunidades e residem em Tampere, na Finlândia, onde frequentam escolas cuja língua de ensino é o finlandês. O presente trabalho pretende, por um lado, dar conta da realidade sociocultural daqueles alunos de Português Língua Não-Materna, e, por outro, visa refletir sobre a aquisição/ aprendizagem da competência pragmática por parte destes sujeitos, falantes de herança, através da realização que fazem de atos ilocutórios diretivos – de pedido e de ordem –, bem como, sobre o grau de formalização das expressões de delicadeza que fazem. Por conseguinte, elaborámos uma Ficha Sociolinguística para recolha de dados referentes ao contexto familiar, sociocultural e linguístico dos alunos. Posteriormente, elaborámos e aplicámos um teste linguístico, de Tarefas de Elicitação do Discurso, com vista à recolha de dados para a construção de um corpus linguístico que nos permitisse desenvolver o presente estudo. A aplicação do teste linguístico e consequente tratamento dos dados recolhidos revelaram que as escolhas pragmáticas dos sujeitos são condicionadas pelo contexto sociocultural e linguístico em que estão imersos. Constatámos, igualmente, que a generalidade dos alunos recorre a duas estratégias de mitigação do discurso, pelo uso de duas expressões de delicadeza: a fórmula «se faz favor»/«por favor» e o verbo modal «poder».

Retratar a caminhada ao longo do estágio de natureza profissional “gravidez, trabalho de parto e pós-parto” de forma crítica e fundamentada, é o pressuposto basilar do relatório de estágio do 2º Ciclo de Estudos conducente ao grau de mestre em enfermagem de saúde materna e obstétrica. O pensamento crítico – reflexivo é o elemento chave para o progresso e aperfeiçoamento profissional da enfermagem, sendo utilizado para transmitir todo o processo de desenvolvimento ao longo desta experiência formativa. Neste contexto, as competências específicas do Enfermeiro Especialista em Enfermagem de Saúde Materna e Obstétrica, criadas pela Ordem dos Enfermeiros, foram analisadas e verificadas recorrendo à prática baseada em evidências, ao mesmo tempo que foram contextualizados e mobilizados os conhecimentos adquiridos. Na área da saúde, o acompanhamento atualizado dos resultados de pesquisa, tornou-se uma prática inadiável, visto que é fundamental a adoção de medidas que minimizem as discrepâncias entre os avanços científicos e a prática assistencial. A prática baseada em evidências é a utilização da melhor evidência científica e contribui na tomada de decisão clínica, neste cenário emerge o método da revisão integrativa da literatura que tem a finalidade de reunir e sintetizar os resultados de pesquisas, de maneira sistemática e ordenada, contribuindo para o aprofundamento do conhecimento do tema investigado. Neste trabalho investigamos se os Enfermeiros Especialistas em Enfermagem de Saúde Materna e Obstétrica promovem estratégias de empowerment na preparação para o parto. Esta problemática surgiu da necessidade de compreender a importância do empowerment, e, se trabalhado nas aulas de preparação para o parto, em que medida poderia alterar os resultados, perceções/vivências da mulher durante o trabalho de parto e parto. VI Os dados encontrados, ainda que não estejam bem explorados, confirmam a relevância do conceito de empowerment no contexto da obstetrícia, fazem-nos refletir sobre a diversidade de práticas assistenciais, nos métodos de preparação para o parto e na necessidade de uma uniformização dos cuidados. Apostar na investigação do empowerment surge como essencial para expandir o conhecimento sobre a atuação do Enfermeiro Especialista em Enfermagem de Saúde Materna e Obstétrica e ganhos em saúde consequentes.
