DIRETOR DE ESCOLA: GERENTE OU EDUCADOR? POSSIBILIDADES E LIMITAÇÕES DO DESENVOLVIMENTO DA FUNÇÃO PEDAGÓGICA EM UMA ESCOLA PÚBLICA ESTADUAL PAULISTA

Há tempo, as dificuldades enfrentadas pelos diretores de escola da rede pública estadual de São Paulo constituem motivo de inquietação e impotência, pois estes têm seu trabalho engessado pela rotina burocrático-administrativa, a qual dificulta o desempenho das atividades pedagógicas. Este trabalho centra-se no estudo das possibilidades e limites no desenvolvimento da função pedagógica do Diretor de Escola, aliás, Gerente ou Educador? Nesta pesquisa utiliza-se dos documentos da Unidade Escolar, desde sua fundação em 1985 até 2007, para se entender o desenvolvimento da função de diretor de escola, neste duplo aspecto burocráticoadministrativo e pedagógico. Desta forma, foram abordadas as seguintes questões: quais são as solicitações e exigências da Secretaria de Estado da Educação de São Paulo (SEE-SP) e dos órgãos a ela subordinados em relação às atividades desenvolvidas cotidianamente pelo diretor de escola? Quais as incumbências objetivas que o diretor de escola tem que responder para a SEE-SP? A partir disso, quais são as possibilidades e os limites do diretor para desenvolver a função pedagógica no ambiente escolar? A hipótese aventada é que, o diretor de escola não consegue centrar-se no desenvolvimento das atividades pedagógicas em face do atendimento às exigências burocrático-administrativas da SEE-SP e dos órgãos a ela subordinados, os quais condicionam sua atividade profissional. Pretende-se com este estudo contribuir para o debate acerca da prática da gestão escolar e da reflexão da função e do papel do diretor de escola no processo de transformação econômico-político-social. A apresentação desta pesquisa está estruturada em três capítulos. As considerações finais apontam que o diretor de escola, devido ao grande número de solicitações e exigências de tarefas burocrático-administrativas, emanadas do poder central e de seus órgãos subordinados, vê comprometido o desempenho das funções pedagógicas.(AU)

Compilation of respiration rate data for marine pelagic organisms

The metabolic rate of organisms may either be viewed as a basic property from which other vital rates and many ecological patterns emerge and that follows a universal allometric mass scaling law; or it may be considered a property of the organism that emerges as a result of the organism's adaptation to the environment, with consequently less universal mass scaling properties. Data on body mass, maximum ingestion and clearance rates, respiration rates and maximum growth rates of animals living in the ocean epipelagic were compiled from the literature, mainly from original papers but also from previous compilations by other authors. Data were read from tables or digitized from graphs. Only measurements made on individuals of know size, or groups of individuals of similar and known size were included. We show that clearance and respiration rates have life-form-dependent allometries that have similar scaling but different elevations, such that the mass-specific rates converge on a rather narrow size-independent range. In contrast, ingestion and growth rates follow a near-universal taxa-independent ~3/4 mass scaling power law. We argue that the declining mass-specific clearance rates with size within taxa is related to the inherent decrease in feeding efficiency of any particular feeding mode. The transitions between feeding mode and simultaneous transitions in clearance and respiration rates may then represent adaptations to the food environment and be the result of the optimization of tradeoffs that allow sufficient feeding and growth rates to balance mortality.

Comparison of radiobiological effects induced by ultra-high and standard dose rate of x-rays on a radio-resistant cell line

Radiotherapy (RT) has recently evolved with the emergence of heavy ion radiations or new fractionation schemes of photon therapy, which modify the dose rate of treatment delivery. The aim of the present study was then to evaluate the in vitro influence of a ultra-high dose rate comparing them with standard dose rate. In this regard, a radioresistant SK-MEL-28 cell line were irradiated with x-ray in order to have a total dose of 2 and 4 Gy, at two different dose rate. The ultra-high dose rate is a specific property of the dense plasma focus (DPF) device, which has pulsed operation and thus gives short and highly energetic pulses of multiple types of rays and particles, in this case, we focused our study on the influence of X-rays. While a low dose rate is obtained with conventional X-ray tube. In this study it results that a ultra-high dose rate enhances radiosensitivity of melanoma cells while reducing the adhesion, proliferation and migration ability of cells.

Data collection of Calanus finmarchicus reproduction life history traits in the North Atlantic Ocean

Observations of egg production rates (EPR) for female Calanus finmarchicus were compared from different regions of the North Atlantic. The regions were diverse in size and sampling frequency, ranging from a fixed time series station in the Lower St Lawrence Estuary, off Rimouski, where nearly 200 experiments were carried out between May and December from 1994 to 2006, to a large-scale survey in the Northern Norwegian Sea, where about 50 experiments were carried out between April and June from 2002 to 2004. For this analysis the stations were grouped mostly along geographic lines, with only limited attention being paid to oceanographic features. There is some overlap between regions, however, where stations were sometimes kept together when they were sampled on the same cruise. As well some stations other than off Rimouski were occupied more than once during different years and/or in different seasons.
