Para que serve a pesquisa em educação?

Constatada uma crescente insatisfação, por parte de gestores da escola pública diante das pesquisas desenvolvidas na universidade, o artigo analisa as relações entre a pesquisa e as práticas educativas, procurando mostrar as diversas influências cruzadas existentes. Com base nos escritos de Charlot, Rayou, Dubet, Tardif e Zourhlal, o texto examina as diferentes formas como os atores sociais incorporam e reinterpretam resultados de pesquisa em suas concepções sobre a educação e, também, como a produção acadêmica é marcada por disputas que se originam na dinâmica social mais ampla. Um comentário crítico específico é feito sobre o movimento em favor de "práticas e políticas baseadas em evidências", tendência que tem prosperado nos meios educacionais de fala inglesa, defendendo um modelo experimental de pesquisa que, baseado em amostras aleatórias, é considerado como o único que poderia oferecer resultados confiáveis para subsidiar políticas públicas de educação. O artigo sugere, em lugar da pergunta "para que serve?", uma indagação a respeito de como circulam conhecimentos e opiniões entre os dois campos. Conclui enfatizando o fato de que a pesquisa é uma atividade humana como as outras, pois a universidade e os centros de pesquisa não estão fora da sociedade. Nesse sentido, o artigo aponta para a potencialidade de um diálogo aberto entre os dois modos de conhecer e agir, aquele da investigação e da reflexão crítica e aquele da ação política e profissional.

08006-003 East Okoboji Beach Final Report

East Okoboji Beach was platted on April 20, 1961 and includes over 90.4 acres with 489 lots. The East Okoboji Beach project includes a complete storm water discharge system, which includes low impact development and reconstruction of the roadways in East Okoboji Beach. The East Okoboji Beach Project is an enormous project that is the first Dickinson County project to retrofit LID practices, lake-friendly storm-water drainage systems and roadway reconstruction throughout an existing sub- division. This cooperative project between DNR, Dickinson County, and EOB landowners includes engineering retention ponds, rain gardens, bio-swales and other LID practices to reduce nutrient and sediment pollutants flowing directly into East Okoboji. The nature of the problem stems back to that original plat where small lots were platted and developed without planning for storm water discharge. There was no consideration of the effects of filling in and developing over the many wetland areas existing in EOB. The scope of the problem covers the entire 90.4 acres in East Okoboji Beach, the DNR owned land and the farmed land to the east. The nature of the problem stems from storm water runoff flowing throughout the watershed and into East Okoboji Beach where it flows down self-made paths and then into East Lake Okoboji. That storm water runoff dumps nutrient and sediment pollutions directly into East Lake Okoboji. The expected result of this project is a new roadway and drainage system constructed with engineering that is intended to protect East Lake Okoboji and the land and homes in East Okoboji Beach. The benefit will be the improvement in the waters and the reduction of the siltation in the East Lake Okoboji.

Vanishing Clams on an iberian beach: local consequences and global implication of accelerating loss of shells to tourism

Multi-decadal increase in shell removal by tourists, a process that may accelerate degradation of natural habitats, was quantified via two series of monthly surveys, conducted thirty years apart (1978-1981 and 2008-2010) in one small embayment on the Mediterranean coast of Spain. Over the last three decades, the local tourist arrivals have increased almost three-fold (2.74), while the area has remained unaffected by urban encroachment and commercial fisheries. Concomitantly, abundance of mollusk shells along the shoreline decreased almost three-fold (2.62) and displayed a tight inverse correlation with tourist arrivals. A four-fold increase in tourist arrivals observed globally over the last 30 years has likely induced a comparable worldwide acceleration in shell removal from marine shorelines and exerted multiple negative (but currently unquantifiable) habitat changes that may include increased beach erosion, changes in carbon and calcium cycles, and decline in diversity and abundance of organisms dependent on shell availability.

Under the Stones, the beach. Vínculos generacionales y pulsiones subversivas en el cine a través de los Rolling Stones

Este trabajo busca investigar el fenómeno de lo generacional en el cine a través de su relación con la música. Para ello, utiliza como punto de partida la filmografía de los Rolling Stones y aplica elconcepto de aura de Walter Benjamin. Así, explora las tensiones generacionales entre jóvenes y adultos, que se reflejan en los ámbitos del creador, la audiencia y la industria como tensiones entre invención y comercialización, entre libertad y represión o entre rebeldía y conservadurismo. De ese modo, procura identificar en la puesta en escena la capacidad contracultural del cine que apela a lo juvenil y oponerla a los simulacros oportunistas que utiliza el sistema de la industria cultural.

Vacuolar SNARE Protein Transmembrane Domains Serve as Nonspecific Membrane Anchors with Unequal Roles in Lipid Mixing.

Membrane fusion is induced by SNARE complexes that are anchored in both fusion partners. SNAREs zipper up from the N to C terminus bringing the two membranes into close apposition. Their transmembrane domains (TMDs) might be mere anchoring devices, deforming bilayers by mechanical force. Structural studies suggested that TMDs might also perturb lipid structure by undergoing conformational transitions or by zipping up into the bilayer. Here, we tested this latter hypothesis, which predicts that the activity of SNAREs should depend on the primary sequence of their TMDs. We replaced the TMDs of all vacuolar SNAREs (Nyv1, Vam3, and Vti1) by a lipid anchor, by a TMD from a protein unrelated to the membrane fusion machinery, or by artificial leucine-valine sequences. Individual exchange of the native SNARE TMDs against an unrelated transmembrane anchor or an artificial leucine-valine sequence yielded normal fusion activities. Fusion activity was also preserved upon pairwise exchange of the TMDs against unrelated peptides, which eliminates the possibility for specific TMD-TMD interactions. Thus, a specific primary sequence or zippering beyond the SNARE domains is not a prerequisite for fusion. Lipid-anchored Vti1 was fully active, and lipid-anchored Nyv1 permitted the reaction to proceed up to hemifusion, and lipid-anchored Vam3 interfered already before hemifusion. The unequal contribution of proteinaceous TMDs on Vam3 and Nyv1 suggests that Q- and R-SNAREs might make different contributions to the hemifusion intermediate and the opening of the fusion pore. Furthermore, our data support the view that SNARE TMDs serve as nonspecific membrane anchors in vacuole fusion.

Multitude libre/Multitude serve. Pour une lecture du Traité politique de Spinoza

Cette étude se donne pour objet de dégager la visée poursuivie par Spinoza dans son Traité politique et d'en extraire l'enseignement politique. Après avoir brièvement reconstruit la théorie spinoziste du droit naturel et l'advenue nécessaire d'un corps politique, elle s'attache, en se basant principalement sur une lecture des chapitres 6 à 11, à déterminer les conditions de la position d'une multitude libre plutôt que serve. On montre que ces conditions se résument dans le principe d'un renforcement circulaire de la puissance du souverain et de celle de la multitude et que la possibilité de son instauration repose sur une juste compréhension de la dynamique passionnelle ; et qu'à défaut, s'installe un régime de servitude marqué par le clivage des gouvernants et de la multitude. On conclut par un regard sur le présent à la lumière de la leçon de ce traité.

Modeling temporal variations of Gracilaria Greville and Hypnea J.V. Lamouroux (Rhodophyta) assemblages on a midlittoral reef platform at Piedade Beach, Pernambuco State, Brazil

The diversity of algal banks composed of species out the genera Gracilaria Greville and Hypnea J.V. Lamouroux have been impacted by commercial exploitation and coastal eutrophication. The present study sought to construct dynamic models based on algal physiology to simulate seasonal variations in the biomasses of Gracilaria and Hypnea an intertidal reef at Piedade Beach in Jaboatão dos Guararapes, Pernambuco State, Brazil. Five 20 × 20 cm plots in a reef pool on a midlittoral reef platform were randomly sampled during April, June, August, October, and December/2009 and in January and March/2010. Water temperature, pH, irradiance, oxygen and salinity levels as well as the concentrations of ammonia, nitrate and phosphate were measured at the sampling site. Forcing functions were employed in the model to represent abiotic factors, and algal decay was simulated with a dispersal function. Algal growth was modeled using a logistic function and was found to be sensitive to temperature and salinity. Maximum absorption rates of ammonia and phosphate were higher in Hypnea than in Gracilaria, indicating that the former takes up nutrients more efficiently at higher concentrations. Gracilaria biomass peaked at approximately 120 g (dry weight m-2) in March/2010 and was significantly lower in August/2009; Hypnea biomasses, on the other hand, did not show any significant variations among the different months, indicating that resource competition may influence the productivity of these algae.
