O tema desta dissertação é a Avaliação Institucional da Educação Básica. Para tal, faz-se a análise do processo de avaliação, com ênfase no instrumento utilizado pelas Escolas Adventistas de nível básico do estado de São Paulo, considerando que a educação adventista se tornou uma parte consistente dentro da estrutura da Igreja Adventista do Sétimo Dia. Procurou-se, neste trabalho, como objetivo geral, compreender como se configura a prática da avaliação institucional das escolas da Rede Adventista de Educação. O método da investigação incluiu análise bibliográfica dos principais teóricos da área de políticas públicas e do sistema privado bem como da avaliação institucional, seguido de exame documental do instrumento utilizado no processo de avaliação institucional. O estudo resgata a contextualização histórica do desenvolvimento da escola privada, destacando aspectos relevantes de sua relação com o Estado. Também apresenta brevemente a história da Igreja Adventista do Sétimo Dia (IASD) nos Estados Unidos (EUA) e no Brasil, de modo a situar o surgimento do sistema educacional adventista, bem como a sua filosofia de ensino, buscando conhecer as origens desse grupo religioso que há mais de um século atua no cenário educacional brasileiro. Em seguida, aborda aspectos da Avaliação Institucional. Finalmente, apresenta-se uma síntese do processo e uma descrição analítica do instrumento de avaliação institucional das escolas de nível básico da Educação Adventista. Na conclusão do trabalho, não se encontraram indícios de que o conceito adventista de avaliação educacional seja diferente do das abordagens tradicionais. Entretanto, na concepção adventista de avaliação, existe mais fortemente a preocupação de se manter um processo de avaliação contínuo e sistemático.

A potent, orally active growth hormone (GH) secretagogue L-163,191 belonging to a recently synthesized structural class has been characterized. L-163,191 releases GH from rat pituitary cells in culture with EC50 = 1.3 +/- 0.09 nM and is mechanistically indistinguishable from the GH-releasing peptide GHRP-6 and the prototypical nonpeptide GH secretagogue L-692,429 but clearly distinguishable from the natural GH secretagogue, GH-releasing hormone. L-163,191 elevates GH in dogs after oral doses as low as 0.125 mg/kg and was shown to be specific in its release of GH without significant effect on plasma levels of aldosterone, luteinizing hormone, thyroxine, and prolactin after oral administration of 1 mg/kg. Only modest increases in cortisol were observed. Based on these properties, L-163,191 has been selected for clinical studies.

The work in this sub-project of ESOP focuses on the advective and convective transforma-tion of water masses in the Greenland Sea and its neighbouring areas. It includes observational work on the sub-mesoscale and analysis of hydrographic data up to the gyre-scale. Observations of active convective plumes were made with a towed chain equipped with up to 80 CTD sensors, giving a horizontal and vertical resolution of the hydrographic fields of a few metres. The observed scales of the penetrative convective plumes compare well with those given by theory. On the mesoscale the structure of homogeneous eddies formed as a result of deep convection was observed and the associated mixing and renewal of the intermediate layers quantified. The relative importance and efficiency of thermal and haline penetrative convection in relation to the surface boundary conditions (heat and salt fluxes and ice cover) and the ambient stratification are studied using the multi year time series of hydro-graphic data in the central Greenland Sea. The modification of the water column of the Greenland Sea gyre through advection from and mixing with water at its rim is assessed on longer time scales. The relative contributions are quantified using modern water mass analysis methods based on inverse techniques. Likewise the convective renewal and the spreading of the Arctic Intermediate Water from its formation area is quantified. The aim is to budget the heat and salt content of the water column, in particular of the low salinity surface layer, and to relate its seasonal and interannual variability to the lateral fluxes and the fluxes at the air-sea-ice interface. This will allow to estimate residence times for the different layers of the Greenland Sea gyre, a quantity important for the description of the Polar Ocean carbon cycle.

During Ocean Drilling Program Leg 191, ~100 m of mid-Cretaceous igneous crust was cored at Site 1179 (41.08°N, 159.96°E), located within magnetic Anomaly M8 on the abyssal plain of the northwest Pacific Ocean near Shatsky Rise. Paleomagnetic data from this section are significant because they can constrain the mid-Cretaceous Pacific plate paleolatitude and paleomagnetic pole, both of which can be used to infer tectonic drift and other geodynamic processes. In this study, we analyzed the paleomagnetism of 122 samples from 40 flows in the Site 1179 basalt section. Comparison of inclination data among flows implies 13 independent measurements of the paleomagnetic field. Assuming a reversed magnetic polarity because of the site location within Anomaly M8, the data give a mean paleocolatitude of 88.1° ± 6.8° (corresponding to a paleolatitude of 1.9°N). The paleocolatitude is consistent with other mid-Cretaceous Pacific paleomagnetic data that indicate ~39° northward drift of the western Pacific plate since mid-Cretaceous time. Comparison of observed between-flow colatitude variance with that expected from secular variation data suggests that secular variation may not have been completely averaged with the 13 independent groups sampled at Site 1179. Colatitude scatter in the section is markedly less in the deepest 33 m of the hole, indicating a shift from rapidly erupted flows in the bottom ~33 m of the section to more slowly emplaced flows above.

The sensitivity of the tropics to climate change, particularly the amplitude of glacial-to-interglacial changes in sea surface temperature (SST), is one of the great controversies in paleoclimatology. Here we reassess faunal estimates of ice age SSTs, focusing on the problem of no-analog planktonic foraminiferal assemblages in the equatorial oceans that confounds both classical transfer function and modern analog methods. A new calibration strategy developed here, which uses past variability of species to define robust faunal assemblages, solves the no-analog problem and reveals ice age cooling of 5° to 6°C in the equatorial current systems of the Atlantic and eastern Pacific Oceans. Classical transfer functions underestimated temperature changes in some areas of the tropical oceans because core-top assemblages misrepresented the ice age faunal assemblages. Our finding is consistent with some geochemical estimates and model predictions of greater ice age cooling in the tropics than was inferred by Climate: Long-Range Investigation, Mapping, and Prediction (CLIMAP) [1981] and thus may help to resolve a long-standing controversy. Our new foraminiferal transfer function suggests that such cooling was limited to the equatorial current systems, however, and supports CLIMAP's inference of stability of the subtropical gyre centers.
