Este estudo tem como objetivo analisar a gestão de uma incubadora de Empresas, o Programa de Incubação de Empresas de Base Tecnológica (PIEBT). Partindo de uma abordagem qualitativa e quantitativa, buscou-se retratar o processo gerencial da mais antiga Incubadora de empresas amazônica, identificando seu contexto e o nível de adequação de suas práticas ao mais novo modelo de gestão de incubadoras, o Centro de Referência para Apoio a Novos Empreendimentos (CERNE). Para isso, foi discorrido sobre a incubação de empresas, discutindo conceitos de gestão e alguns aspectos da teoria institucional. Os resultados permitiram verificar que a gestão tem foco central no processo de incubação e na captação de recursos e seu nível de adequação ao CERNE encontra-se, predominantemente, em estágio inicial, mas, que, até por pressões de seu campo organizacional, a implementação do modelo é uma meta a ser alcançada. Concluiu-se também que a gestão do PIEBT é circundada por pressões que tendem ao isomorfismo.

O câncer colorretal é um grave problema de saúde pública na região norte, sendo a 3a neoplasia mais frequente entre os homens e a 2a entre as mulheres. Cerca de 10% destes tumores são hereditários e a polipose adenomatosa familial está entre as principais causas destes. Mutações no gene APC são responsáveis pelo desenvolvimento de tumores nestes pacientes e estão presentes desde a fase mais precoce na carcinogênese, além disso, existe uma relação entre o tipo de mutação e apresentação clínica da doença. Até o presente momento não existe uma publicação com o perfil de mutação do gene APC na região norte do país. Este trabalho tem como objetivo principal, identificar o perfil de mutações no gene APC em famílias do estado do Pará. Um total de 15 pacientes foi analisado provenientes de cinco famílias, todos atendidos no UNACON do HUJBB. Foi realizado a extração de DNA do sangue periférico e realizado um sequenciamento direto em um membro de cada família, obtendo desta forma um screening molecular e os demais membros da família foram genotipados pela técnica ARMS. A análise estatística foi realizada pelos softwares que acompanham o próprio produto. Neste estudo foram encontrados mutações nos 15 membros estudados (provenientes das 5 famílias), 40% das quais eram do tipo frameshift, 35% silenciadoras e 20% nonsense. Sendo que 60% de todas as mutações ocorreram na região MCR. Entre as três mutações mais frequentes na literatura, neste estudo foram encontradas duas: códon 1309 (em 40% dos indivíduos) e no códon 1061 (em 10% dos indivíduos). Estes números foram bem diferentes dos encontrados na literatura, reforçando o papel da miscigenação na frequência das mutações. A mutação c.3956delC foi a única encontrada em todas as famílias analisadas, o que pode comportar-se como um forte biomarcador desta síndrome. A avaliação clínica dos pacientes confirmou a correlação genótipo/fenótipo, sendo um fator determinante para o direcionamento clínico e aconselhamento genético. A plataforma confeccionada para análise de mutações pela técnica ARMS será de grande utilidade, já que conseguiu detectar mutações no 15 indivíduos estudados a um custo bem inferior que o sequenciamento direto por PCR.

Leprosy in children is correlated with community-level factors, including the recent presence of disease and active foci of transmission in the community. We performed clinical and serological examinations of 1,592 randomly selected school children (SC) in a cross-sectional study of eight hyperendemic municipalities in the Brazilian Amazon Region. Sixty-three (4%) SC, with a mean age of 13.3 years (standard deviation = 2.6), were diagnosed with leprosy and 777 (48.8%) were seropositive for anti-phenolic glycolipid-I (PGL-I). Additionally, we evaluated 256 house-hold contacts (HHCs) of the students diagnosed with leprosy; 24 (9.4%) HHC were also diagnosed with leprosy and 107 (41.8%) were seropositive. The seroprevalence of anti-PGL-I was significantly higher amongst girls, students from urban areas and students from public schools (p < 0.0001). Forty-five (71.4%) new cases detected amongst SC were classified as paucibacillary and 59 (93.6%) patients did not demonstrate any degree of physical disability at diagnosis. The results of this study suggest that there is a high rate of undiagnosed leprosy and subclinical infection amongst children in the Amazon Region. The advantages of school surveys in hyperendemic areas include identifying leprosy patients at an early stage when they show no physical disabilities, preventing the spread of the infection in the community and breaking the chain of transmission.

Forest cover has importance within the context of the water balance of a particular site and may alter the mechanism of entry of water and nutrients to the soil surface. The aim of this study was to quantify the net precipitation, interception, addition of nutrients in throughfall and stem flow in a forest in different stages of regeneration of Mata Atlantica: early-stage secondary forest (ESSF), intermediary stage secondary forest (ISSF) and advanced stage secondary forest (AESF). The study was conducted in Pinheiral, Rio de Janeiro state. The data collection was performed during the period of April 2009 to March 2010. The values of incident precipitation, effective precipitation and interception were similar among the three stages evaluated. The AESF area showed higher values of Mg and P in the addition of nutrients from throughfall compared with other areas assessed. The pH of the precipitation incident did not differ among areas, but was higher than the pH of rainfall. The three areas evaluated showed no difference in the addition of nutrients to flow through the trunk. The AESF area showed a trend of higher levels of addition of nutrients from throughfall precipitation and runoff from stemflow.

Learning to read and write at an early stage is the process of transferring the sound form of the spoken language for the graphical form of writing, a process, a time that in our system of alphabetical called writing, the letters are graphical representations in the level of phoneme. So that this representation occurs, it is necessary that the individual already can of some form perceive and manipulate the different sonorous segments of the word. This capacity of perception directed to the segments of the word calls Phonological Awareness. Thus, it was established had for objective to verify the pertaining to school performance of 1ª to 4ª series with and without of learning in Tests of Phonological Awareness. Fourth children with age average of 9 years and 3 months without learning disabilities had been submitted to the Protocol of Phonological Awareness (CIELO, 2002) using of this instrument had participated of this study 80 pertaining to school of both only the phonological tasks. The data received from quantiqualitative approach whose results were extracted inferences. The statistically significant results occurred in the tasks of Realism Face Detection, Syllables, Detecting Phonemes, Phonemic Synthesis and Reversal Phonemic. Based on the results we observed that children without learning difficulties performed better on all tasks mentioned above

This paper analyzes unconventional segmentation of word found in texts of the sixth grade of Elementary School. Through quantitative and qualitative analysis, we describe the prosodic characteristics that may be motivated the hyper and hippossegmentation of words found in 27,4% of 606 investigated texts. We identified a tendency toward a more text with hippossegmentation than hypersegmentation, characteristic similar to what is reported about children’s text. Taking into account the theoretical framework of Prosodic Phonology, we argue about the relevance of prosodic word and clitic group in the description of the regularities observed in data of unconventional segmentation of word. We note that (i) in cases of hipposegmentation, it predominates the hollow of a clitic followed by a phonological word, (ii) in cases of hypersegmentation, it predominates a segmentation of a prosodic word into a clitic group. We present evidences to be the spelling of clitic elements a challenge to students analyzed. By investigating in the grammatical class that owned the clitics spelled unconventionally, we verified that they are prepositions (“em, de, com”) and pronouns (“me, lhe, lo”), a characteristic that particularize these data in relation to data from students in the early stage of language acquisition.

Attention is a phenomenon that allows the selection of relevant stimuli in order to prioritize them and improve their processing. This modulation could occur in any step of the process: in an early stage or in a late stage, more precisely, in a perceptive or motor stage. However, even with a rich literature about attention in time, there are still some divergences about how this modulation occurs. A hypothesis about it says that temporal attention would only be able to prepare the motor system to respond. The perceptual modulation would only occur when the temporal expectation is in combination with another expectation of a property with neuronal receptive field. In this situation, the receptive field's pre-activation is the explanation of how temporal attention would be capable to modulate perceptual process. The crucial objective was to test this hypothesis. In other words, it was to verify if the feature expectation of a stimulus (Gabor orientation) and its temporal expectancy interferes in perception quality. Two experiments were made: the first one tested the voluntary temporal expectation, and the second one tested the automatic temporal expectation. Our data shows that both Feature-based Attention and Temporal Attention improve the process of perception. Temporal expectation effects just occur in situations of competitive environment. Hypothesis verification was not conclusive, because of methodological problems
