Desempenho profissional do psicólogo escolar: relação entre conhecimento da amplitude de suas funções e limites institucionais

Este estudo foi elaborado em função da necessidade de sistematização das múltiplas questões levantadas em torno da eficácia da Psicologia Escolar que, de certa forma, esvaziam e comprometem sua vital importância no contexto Educacional brasileiro. Para um maior aprofundamento na análise das questões referentes à atuação do Psicólogo Escolar, utilizou-se enfoque epistemológico referente à construção do "real", através dos "possíveis" e dos "necessários" em Educação. Foi realizada uma investigação de campo com trinta e três Psicólogos Escolares de escolas particulares com o objetivo de analisar suas funções, a fim de diagnosticar as limitações das mesmas e suas possíveis causas, bem como a amplitude de suas propostas de atuação. Foram levantadas hipóteses para uma melhor compreensão dos motivos que levariam o Psicólogo Escolar a desempenhar suas funções numa tendência mais institucional dentro do contexto educativo ou mais clínica. Os resultados revelam que 67% dos Psicólogos Escolares conhecem a amplitude de suas funções e procuram assumí-las plenamente apesar dos limites que a Instituição oferece, estando sua atuação, mais ligada aos aspectos institucionais. Foi, igualmente, feita uma análise dos motivos que levam os Diretores de escolas a contratar um Psicólogo Escolar, sendo utilizada uma amostra de trinta e quatro escolas, que possuem ou não Psicólogos Escolares. A partir desses resultados pode-se afirmar que quanto mais o Psicólogo Escolar conhecer e assumir a amplitude de suas funções, mais facilmente poderá romper com os limites e dificuldades da própria Instituição, uma vez que, através da análise das possibilidades e necessidades do contexto institucional, terá condições para viabilizar a construção de um "real" educativo. Na medida em que o Psicólogo Escolar assumir sua identidade profissional, abrirá novas perspectivas de trabalho e espaços dentro da própria instituição escolar.

Amplitude e restrições ao acesso de Pronaf Investimento no Rio Grande do Sul : um estudo de três operações de financiamento envolvendo cooperativas de crédito rural, cooperativas de produção agropecuária e o Banco Regional de Desenvolvimento do Extremo Sul

Passados dez anos da sua criação, é inconteste a relevância do Pronaf como fonte de recursos para o financiamento e para o fornecimento de liquidez para os agricultores familiares. Mas persistem dificuldades de acesso, particularmente ao Pronaf Investimento, justamente a modalidade que permite que estes agricultores realizem investimentos na sua estrutura produtiva, decisivos para a sua reprodução social. Com o objetivo de contribuir com o debate acerca do financiamento do desenvolvimento rural, este trabalho analisou o processo de intermediação financeira do Pronaf Investimento realizado através do Sistema BNDES, envolvendo o BRDE, cooperativas de crédito rural como instituições financeiras repassadoras e cooperativas de produção agropecuária como avalistas das operações de financiamento dos agricultores. Foi procedida uma avaliação do desempenho do Pronaf e, em seguida, relatadas as restrições ao acesso de Pronaf Investimento causadas pela insuficiência de limites operacionais por parte das cooperativas de crédito rural e sua relação com as regras do Sistema Financeiro Nacional derivadas do Acordo de Capital da Basiléia. Por fim, foram relatadas três operações de financiamento envolvendo cooperativas de crédito rural, cooperativas de produção agropecuária e o BRDE. As hipóteses inicialmente aventadas foram confirmadas. Os dirigentes das cooperativas de crédito rural apontaram a insuficiência de limites operacionais por parte das suas respectivas cooperativas como a mais significativa restrição ao acesso de Pronaf Investimento e as operações analisadas permitiram a superação destes limites, assim como a elevação do montante disponível de recursos de R$ 1,205 milhão de reais para R$ 4,855 milhões de reais. Portanto, pode-se afirmar que é possível superar a principal restrição ao acesso de Pronaf Investimento onde atuam cooperativas de crédito rural, qual seja, o limite operacional estabelecido pelas regras derivadas do Acordo de Capital da Basiléia, e que esta superação propicia um aumento do repasse de Pronaf Investimento, fator decisivo para o financiamento da agricultura familiar.

Analysis of contagion from the constant conditional correlation model with Markov regime switching

Over the last decades, the analysis of the transmissions of international nancial events has become the subject of many academic studies focused on multivariate volatility models volatility. The goal of this study is to evaluate the nancial contagion between stock market returns. The econometric approach employed was originally presented by Pelletier (2006), named Regime Switching Dynamic Correlation (RSDC). This methodology involves the combination of Constant Conditional Correlation Model (CCC) proposed by Bollerslev (1990) with Markov Regime Switching Model suggested by Hamilton and Susmel (1994). A modi cation was made in the original RSDC model, the introduction of the GJR-GARCH model formulated in Glosten, Jagannathan e Runkle (1993), on the equation of the conditional univariate variances to allow asymmetric e ects in volatility be captured. The database was built with the series of daily closing stock market indices in the United States (SP500), United Kingdom (FTSE100), Brazil (IBOVESPA) and South Korea (KOSPI) for the period from 02/01/2003 to 09/20/2012. Throughout the work the methodology was compared with others most widespread in the literature, and the model RSDC with two regimes was de ned as the most appropriate for the selected sample. The set of results provide evidence for the existence of nancial contagion between markets of the four countries considering the de nition of nancial contagion from the World Bank called very restrictive. Such a conclusion should be evaluated carefully considering the wide diversity of de nitions of contagion in the literature.

A natureza das práticas de governança corporativa no Brasil

Este estudo traça a evolução das práticas de governança corporativa das empresas brasileiras entre os anos de 2010 e 2014 e investiga elementos operacionais e mercadológicos que precedem as decisões das empresas em adotarem melhores ou piores práticas. Para isso, foram levantados dados de fontes primárias que deram origem ao Índice de Qualidade de Governança Corporativa (IQGC), composto por quatro sub elementos: Estrutura do Conselho de Administração; Procedimentos do Conselho de Administração; Direito dos Acionistas Minoritários e; Transparência. Os resultados evidenciam uma constante evolução nas práticas de governança corporativa das empresas ao longo do tempo. Há evidências de que as companhias reconhecem os benefícios de adotarem boas práticas, uma vez que se observa uma evolução de maior amplitude entre as empresas dos segmentos Novo Mercado, Nível 2 e Bovespa Mais. Neste período a maior evolução acontece nas práticas relativas a Estrutura e Procedimentos do Conselho. Entre os elementos operacionais e mercadológicos, destaca-se que empresas mais lucrativas procuram adotar melhores práticas de governança e melhores práticas relacionadas a Transparência nas suas informações. Empresas listadas nos segmentos Nível 1 e Tradicional, onde há maior tangibilidade de suas operações, apresentam melhores práticas relacionadas a Estrutura e Procedimentos do Conselho. Um maior risco das ações leva estas empresas a adotarem melhores práticas relacionadas aos Direitos dos Acionistas Minoritários.

Estudos analíticos dos grafoelementos do eletroencefalograma em sono: fusos do sono, ondas agudas do vértex e o gradiente de freqüência e amplitude, como indicadores de comprometimento neurológico na criança

Innumerable studies have focused been reported on the sleep spindles (SS), Sharp Vertex Waves (SVW) and REM, NREM Sleep as indicators interpreting EEG patterns in children. However, Frequency and Amplitud Gradient (FAG) is rarely cited sleep parameter in children,that occurs during NREM Sleep. It was first described by Slater and Torres, in 1979, but has not been routinely evaluated in EEG reports. The aim of this study was to assess the absence of SS, SVW and FAG, as an indication of neurological compromise in children. The sample consisted of 1014 EEGs of children referred to the Clinical Neurophysiology Laboratory, Hospital Universitário de Brasília (HUB), from January 1997 to March 2003, with ages ranging from 3 months to 12 years old, obtained in spontaneous sleep or induced by choral hydrate. The study was transversal and analytical, in which, visual analysis of EEG traces was perfumed individually and independently by two electroencephalographers without prior knowledge of the EEG study or neurological findings. After EEG selection, the investigators analyzed the medical reports in order to define and correlate neurological pattern was classified according to the presence or absence of neurological compromise, as Normal Neurological Pattern (NNP), and Altered Neurological Pattern (ANP) respectively. From the visual analysis of the EEG(s), it was possible to characterize 6 parameters: 1- FAG present (64,1%); 2- FAG absent (35,9%); 3 - normal SS (87,9%); 4 - altered SS s (12,1%); 5 - normal SVW s (95,7%); 6 - altered SVW s (4,3%). The prevalence of well-formed FAG is found in the 3 months to 5 years age group in the children with NNF. FAG was totally absent from the age of 10 years. When comparing the three sleep graphielements, it was observed that SVW and SS were predominant in children with NNF. However, FAG absent was more prevalent in the ANF than in altered SS an SVW. The statistical analysis showed that there is a strong association of FAG absent, with isolated alteration, in ANF patients, in that the prevalence ratio was 6,60. The association becomes stronger when FAG absent + altered SS(s) is considered (RP= 6,68). Chi-square test, corrected by Yates technique, showed a highly significant relation for FAG ρ= 0,00000001, for error X of 5%, or else the 95% confidence interval (ρ<0,05). Thus, the FAG absent were more expressive in ANF patient than altered SS(s) and SVW(s). The association becomes stronger in order to establish a prognostic relation, when the FAG is combined with the SS. The results os this study allow us to affirm that the FAG, when absent at ages ranging from 3 months to 5 years , is an indication of neurological compromise. FAG is an age-dependent EEG parameter and incorporated systematically, in the interpretation criteria of the EEG of children s sleep, not only in the maturational point of view, but also neurological disturbances with encephalic compromise

Fertility life table of Trichogramma pretiosum and Trichogramma acacioi (Hymenoptera : Trichogrammatidae) on Sitotroga cerealella (Lepidoptera : Gelechiidae) eggs at different constant temperatures

Fertility life tables were developed for both Trichogramma pretiosum and Trichogramma acacioi reared on Sitotroga cerealella eggs as an alternative host at five different temperatures. The egg parasitoids were first collected from Nipteria panacea eggs, a lepidopterous pest of avocado. Egg parasitoid females were individualized in small glass vials along with 40 eggs of the host during 24 h for parasitization. For evaluation of the parasitism capacity, a similar procedure was adopted, but cardboards with eggs were replaced every day. The net reproductive rate (Ro), intrinsic rate of increase (rm), finite rate of increase (lambda), and mean generation time (T) were estimated. Temperature affected all parameters for both Trichogramma species. The highest fecundity for both species was observed at 25degreesC. Extreme temperatures such as 15degreesC or 35degreesC negatively affect the development rate of both species.

Um sistema para estimação da vazão de gás de poços produzindo por Plunger Lift para vaso separador de teste em plataformas de petróleo

This work intends to analyze the behavior of the gas flow of plunger lift wells producing to well testing separators in offshore production platforms to aim a technical procedure to estimate the gas flow during the slug production period. The motivation for this work appeared from the expectation of some wells equipped with plunger lift method by PETROBRAS in Ubarana sea field located at Rio Grande do Norte State coast where the produced fluids measurement is made in well testing separators at the platform. The oil artificial lift method called plunger lift is used when the available energy of the reservoir is not high enough to overcome all the necessary load losses to lift the oil from the bottom of the well to the surface continuously. This method consists, basically, in one free piston acting as a mechanical interface between the formation gas and the produced liquids, greatly increasing the well s lifting efficiency. A pneumatic control valve is mounted at the flow line to control the cycles. When this valve opens, the plunger starts to move from the bottom to the surface of the well lifting all the oil and gas that are above it until to reach the well test separator where the fluids are measured. The well test separator is used to measure all the volumes produced by the well during a certain period of time called production test. In most cases, the separators are designed to measure stabilized flow, in other words, reasonably constant flow by the use of level and pressure electronic controllers (PLC) and by assumption of a steady pressure inside the separator. With plunger lift wells the liquid and gas flow at the surface are cyclical and unstable what causes the appearance of slugs inside the separator, mainly in the gas phase, because introduce significant errors in the measurement system (e.g.: overrange error). The flow gas analysis proposed in this work is based on two mathematical models used together: i) a plunger lift well model proposed by Baruzzi [1] with later modifications made by Bolonhini [2] to built a plunger lift simulator; ii) a two-phase separator model (gas + liquid) based from a three-phase separator model (gas + oil + water) proposed by Nunes [3]. Based on the models above and with field data collected from the well test separator of PUB-02 platform (Ubarana sea field) it was possible to demonstrate that the output gas flow of the separator can be estimate, with a reasonable precision, from the control signal of the Pressure Control Valve (PCV). Several models of the System Identification Toolbox from MATLAB® were analyzed to evaluate which one better fit to the data collected from the field. For validation of the models, it was used the AIC criterion, as well as a variant of the cross validation criterion. The ARX model performance was the best one to fit to the data and, this way, we decided to evaluate a recursive algorithm (RARX) also with real time data. The results were quite promising that indicating the viability to estimate the output gas flow rate from a plunger lift well producing to a well test separator, with the built-in information of the control signal to the PCV

On determining spectral parameters, tracking jitter, and GPS positioning improvement by scintillation mitigation

A method of determining spectral parameters p (slope of the phase PSD) and T (phase PSD at 1 Hz) and hence tracking error variance in a GPS receiver PLL from just amplitude and phase scintillation indices and an estimated value of the Fresnel frequency has been previously presented. Here this method is validated using 50 Hz GPS phase and amplitude data from high latitude receivers in northern Norway and Svalbard. This has been done both using (1) a Fresnel frequency estimated using the amplitude PSD (in order to check the accuracy of the method) and (2) a constant assumed value of Fresnel frequency for the data set, convenient for the situation when contemporaneous phase PSDs are not available. Both of the spectral parameters (p, T) calculated using this method are in quite good agreement with those obtained by direct measurements of the phase spectrum as are tracking jitter variances determined for GPS receiver PLLs using these values. For the Svalbard data set, a significant difference in the scintillation level observed on the paths from different satellites received simultaneously was noted. Then, it is shown that the accuracy of relative GPS positioning can be improved by use of the tracking jitter variance in weighting the measurements from each satellite used in the positioning estimation. This has significant advantages for scintillation mitigation, particularly since the method can be accomplished utilizing only time domain measurements thus obviating the need for the phase PSDs in order to extract the spectral parameters required for tracking jitter determination.

Resonances and subharmonic bifurcations of large amplitude periodic orbits of planar polynomial vector fields

In this work are studied periodic perturbations, depending on two parameters, of planar polynomial vector fields having an annulus of large amplitude periodic orbits, which accumulate on a symmetric infinite heteroclinic cycle. Such periodic orbits and the heteroclinic trajectory can be seen only by the global consideration of the polynomial vector fields on the whole plane, and not by their restriction to any compact set. The global study involving infinity is performed via the Poincare Compactification. It is shown that, for certain types of periodic perturbations, one can seek, in a neighborhood of the origin in the parameter plane, curves C-(m) of subharmonic bifurcations, for which the periodically perturbed system has subharmonics of order m, for any integer m.
