Avaliação escolar no ensino superior de letras: entre o discurso e a prática

O objeto desta pesquisa é a avaliação da aprendizagem, tendo como foco central a análise dos discursos e práticas dos professores de Cursos de Licenciatura de Letras. Este estudo foi desenvolvido com docentes de duas instituições de ensino superior do interior do estado da Paraíba, localizado no nordeste brasileiro. O objetivo geral deste estudo é: analisar as semelhanças, diferenças e contradições resultantes da comparação entre os discursos e o que se pratica na avaliação da aprendizagem dos professores de Letras do Ensino Superior de uma instituição de ensino superior particular de Patos/PB e os de uma pública de Catolé do Rocha/PB. Esta foi uma pesquisa qualitativa com uma amostra de cinco docentes de cada estabelecimento de ensino superior, somando-se dez ao todo. Foram feitas entrevistas com perguntas abertas e fechadas, cujas respostas tiveram uma análise de conteúdo, e o resultado desta foi confrontado com os dados da observação das práticas de sala de aula dos professores da amostra. Constatou-se que há casos de professores que têm discursos diferentes da sua prática de avaliação da aprendizagem. Há também problemas de interação entre docentes e discentes em relação à avaliação da aprendizagem que aumentam o índice de reprovação do alunado, o que poderia ser evitado. No entanto, de modo geral há um compromisso com a qualidade de ensino dos docentes entrevistados. Os autores e teóricos que inspiraram esta pesquisa foram: Wachowicz (2000), Castanho (2000), Berbel (2001), Sacristán e Gómez (1998), Hoffman (1996 e 2003), Luckesi (1994), Vasconcelos (2000) e Villas Boas (2000), entre outros.

De la fidelidad a la revolución: el proceso de la independencia de la antigua provincia de Guayaquil, 1809-1820 (Estudios)

Este articulo analiza las transformaciones políticas e ideológicas que tuvieron lugar en Guayaquil entre 1809 y 1820, período en el que la ciudad transitó de un marcado fidelismo hacia la autonomía e independencia. Se estudian las disputas entre los grupos de poder local y las reacciones del cabildo a las sucesivas coyunturas peninsulares y regionales. El ensayo muestra la relación entre las tensiones sociales internas y la dinámica, hasta ahora desconocida, de las diferentes elecciones ocurridas entre 1809 y 1813, as¡ como el impacto local de la vigencia y posterior supresión de la constitución gatidatana. El estudio concluye con una reconsideración de la independencia guayaquileña de 1820.

Latinoamericanismo, Barroco de Indias y colonialidad del poder: reflexiones sobre políticas de exclusión (Debates)

Este ensayo examina los debates y las relecturas a propósito del llamado Barroco de Indias que se han originado en el ámbito de los estudios latinoamericanos en las últimas décadas. Se enfoca en los estudios sobre el escritor peruano Juan Espinosa Medrano C1629?-1688, llamado el ""Lunarejo"", y problematiza los postulados que claman ver en el barroco y en sus representantes literarios, los primeros procesos de definición de una identidad y modernidad ""americana"" propias. El autor considera que estas lecturas, a pesar de que buscan responder a interpretaciones colonialistas, rearticulan un proyecto latinoamericanista que excluye las conflictivas relaciones étnico-culturales entre indígenas y no indígenas, así como también refuerza lo que Aníbal Quijano y Walter Mignolo llaman la colonialidad del poder.

Patrimonialismo, conflicto y poder en la reconstrucción de Riobamba, 1797-1822 (Estudios)

Estudio que analiza los conflictos entre las élites de la ciudad de Riobamba y los centros administrativos coloniales de Quito y Santa Fe de Bogotá, a propósito de la reconstrucción de la ciudad luego del terremoto de 1797. La catástrofe puso en evidencia las prácticas políticas y los intereses económicos de la élite criolla riobambeña y del Cabildo de la ciudad. Adicionalmente, se examina la relación de los grupos de poder con la plebe y los indígenas. Estudia además, las divergencias entre los poderes locales y la administración central con respecto al sitio en que se edificaría la nueva ciudad.

Imaginarios urbanos sobre el terremoto de Armenia – Quindío: una visión desde los ciudadanos

Este trabajo recoge el resultado de un proceso investigativo que da cuenta de los imaginarios urbanos generados en los ciudadanos a raíz del terremoto de Armenia, Quindío, en el año 1999. La investigación centra su atención en las formas mediante las cuales se reconfiguraron las estructuras sociales y culturales de los ciudadanos, cómo esto transformó el curso de la ciudad y trazó nuevas territorialidades, hasta el punto de convertir el hecho en un referente que permitió pensar la ciudad a partir de un antes y un después del sismo.

Zinc sorption in selected soils

The adsorption of nutrient elements is one of the most important solid- and liquid-phase interactions determining the retention and release of applied plant nutrients and the efficiency of fertilization. The study showed that the soils with high cation exchange capacity (CEC), CaCO3 , organic matter contents, and heavy texture adsorbed more zinc (Zn). The alkaline soils from Pakistan adsorbed more Zn than English acidic soils. Langmuir and Freundlich isotherm fit was excellent, and r(2) values for the Langmuir isotherm were highly significant (r(2) =0.84 to 0.99). The Langmuir b values, representing the adsorptive capacity of a soil, increased as the texture fineness increased in the soil, with increases in the concentration of adsorptive material (such as organic matter and CaCO3) and with increases in CEC and pH. The alkaline soils from Pakistan had higher bonding energy constant and higher log Kf values than the acidic English soils. Sequential extraction of Zn in these soils showed that most of the Zn was held in CaCO3 pool in the alkaline soils, whereas in acidic soils adsorbed Zn was in exchangeable form.

A structural time series approach to modelling multiple and resurgent meat scares in Italy

This paper exploits a structural time series approach to model the time pattern of multiple and resurgent food scares and their direct and cross-product impacts on consumer response. A structural time series Almost Ideal Demand System (STS-AIDS) is embedded in a vector error correction framework to allow for dynamic effects (VEC-STS-AIDS). Italian aggregate household data on meat demand is used to assess the time-varying impact of a resurgent BSE crisis (1996 and 2000) and the 1999 Dioxin crisis. The VEC-STS-AIDS model monitors the short-run impacts and performs satisfactorily in terms of residuals diagnostics, overcoming the major problems encountered by the customary vector error correction approach.

Incorporating climate change into water resources planning in England and Wales

Public water supplies in England and Wales are provided by around 25 private-sector companies, regulated by an economic regulator (Ofwat) and and environmental regulator (Environment Agency). As part of the regulatory process, companies are required periodically to review their investment needs to maintain safe and secure supplies, and this involves an assessment of the future balance between water supply and demand. The water industry and regulators have developed an agreed set of procedures for this assessment. Climate change has been incorporated into these procedures since the late 1990s, although has been included increasingly seriously over time and it has been an effective legal requirement to consider climate change since the 2003 Water Act. In the most recent assessment in 2009, companies were required explicitly to plan for a defined amount of climate change, taking into account climate change uncertainty. A “medium” climate change scenario was defined, together with “wet” and “dry” extremes, based on scenarios developed from a number of climate models. The water industry and its regulators are now gearing up to exploit the new UKCP09 probabilistic climate change projections – but these pose significant practical and conceptual challenges. This paper outlines how the procedures for incorporating climate change information into water resources planning have evolved, and explores the issues currently facing the industry in adapting to climate change.

Targeted observations of a polar low in the Norwegian sea

A developing polar low is targeted with dropsonde observations to improve the forecast of its landfall. Accurately forecasting a polar low's strength and location remains a challenge; polar lows form over the ocean in poorly observed regions, therefore initial condition errors may contribute significantly to forecast error. The targeted polar low formed in the Norwegian Sea on 3 March 2008, during the Norwegian IPY-THORPEX field campaign. Two flights, six hours apart, released dense networks of dropsondes into a sensitive region covering the polar low and Arctic front to its west. The impact of the targeted observations is assessed using the limited-area Met Office Unified Model and three-dimensional variational (3D-Var) data assimilation scheme. Forecasts were verified using ECMWF analysis data, which show good agreement with both dropsonde data from a flight through the mature polar low, and 10 m QuikSCAT winds. The impact of the targeted data moved southwards with the polar low as it developed and then hit the Norwegian coast after 24 hours. The results show that the forecast of the polar low is sensitive to the initial conditions; targeted observations from the first flight did not improve the forecast, but those from the second flight clearly improved the forecast polar low position and intensity. However, caution should be applied to attributing the forecast improvement to the assimilation of the targeted observations from a single case-study, especially in this case as the forecast improvement is moderate relative to the spread from an operational ensemble forecast

Benefits from safer animal food products: preliminary results from a contingent valuation study of Italian households

The social cost of food scares has been the object of substantial applied research worldwide. In Italy, meat and dairy products are often the vectors of food-borne pathogens, and this is well known by the public. Most cases of food contamination and poisoning find their causes in the way food is handled after, rather than before purchase. However, a large fraction is still caused by mishandling at the industrial stage. With this in mind, we set out to estimate Italian households’ willingness to pay (WTP) for a reduction in the risk of meat and dairy food contamination using contingent valuation. The survey design incorporated features specifically conceived to overcome difficulties faced in previous survey research, especially with respect to individualized food expenditures and risk communication. In order to achieve this objective a CAPI (computer-assisted personal interview) survey was devised to tackle two major issues which emerged in previous contingent valuation studies. The first issue is connected to the way of communicating risk to consumers in order to allow them to make optimal choices and the second one to the results deriving from these studies. In fact, estimates from contingent valuation regarding food safety are given just for single products and so marketers may find it hard to extrapolate them to the aggregate. Our results show that in Italy there are segments of consumers who would benefit from higher standards of food safety for farm animal products.

Satellite Rainfall Estimates Over South America - Possible Applicability to the Water Management of Large Watersheds1

This work analyzes high-resolution precipitation data from satellite-derived rainfall estimates over South America, especially over the Amazon Basin. The goal is to examine whether satellite-derived precipitation estimates can be used in hydrology and in the management of larger watersheds of South America. High spatial-temporal resolution precipitation estimates obtained with the CMORPH method serve this purpose while providing an additional hydrometeorological perspective on the convective regime over South America and its predictability. CMORPH rainfall estimates at 8-km spatial resolution for 2003 and 2004 were compared with available rain gauge measurements at daily, monthly, and yearly accumulation time scales. The results show the correlation between satellite-derived and gauge-measured precipitation increases with accumulation period from daily to monthly, especially during the rainy season. Time-longitude diagrams of CMORPH hourly rainfall show the genesis, strength, longevity, and phase speed of convective systems. Hourly rainfall analyses indicate that convection over the Amazon region is often more organized than previously thought, thus inferring that basin scale predictions of rainfall for hydrological and water management purposes have the potential to become more skillful. Flow estimates based on CMORPH and the rain gauge network are compared to long-term observed average flow. The results suggest this satellite-based rainfall estimation technique has considerable utility. Other statistics for monthly accumulations also suggest CMORPH can be an important source of rainfall information at smaller spatial scales where in situ observations are lacking.
