Regulación del sistema educativo y desigualdades de aprendizaje en el Uruguay

En este artículo se muestra cómo determinados aspectos del sistema uruguayo de educación secundaria pública inciden en rendimientos desiguales de los alumnos. Al utilizar la edición 2006 del Programa Internacional de Evaluación de Estudiantes (pisa) (ocde, 2006a) resaltan tres aspectos clave de las instituciones reguladoras de la educación secundaria que contribuyen a reproducir las desigualdades iniciales, inhibiendo el papel igualador que orienta al sistema educativo. En primer lugar, el mecanismo de asignación de docentes produce un doble efecto de alta rotación de profesores jóvenes en establecimientos de enseñanza de contextos socioculturales desfavorables, así como un anquilosamiento de aquellos docentes más experimentados en establecimientos de contextos favorables. En segundo lugar, el sistema de distribución de alumnos basado en el radio escolar reproduce tel proceso de segregación residencial existente. Finalmente, con el sistema centralizado de provisión de materiales educativos y tecnológicos no se logra cubrir las necesidades de los establecimientos.

Education system institutions and educational inequalities in Uruguay

This article shows how certain aspects at the secondary level of Uruguay’s public school system produce inequalities in student achievement. The 2006 edition of the Programme for International Student Assessment (pisa) (oecd, 2006a) points to three key aspects of the institutions that regulate secondary education that play a part in reproducing inequalities of origin, hindering the equalizing role that guides the education system. First, the teacher assignment mechanism has the dual effect of sending a revolving door of young and inexperienced teachers to schools in unfavourable sociocultural contexts as well as concentrating teachers with more experience in schools in favourable contexts. Second, the geography-based system for assigning students to schools reproduces the residential segregation process. Lastly, the centralized system for supplying educational and technological materials is inadequate to the needs of the schools.

“Lérias, letras, alegres ou tristes” do conto: oralidade e amor em Guimarães Rosa

O estudo da novela "Uma estória de amor", de Guimarães Rosa (1908-1967), que pretendemos desenvolver na realização desta Dissertação de Mestrado, traz como principal mote a recepção crítica e a interpretação das cantigas, narrativas e estórias cantadas e contadas durante a "Festa de Manuelzão" (espécie de subtítulo de "Uma estória de amor"). Desse modo, nosso trabalho terá sua metodologia desenvolvida com fundamento na Estética da Recepção, formulada por Hans Robert Jauss (1921-1997), porém, não se trata de amparar a feitura dessa Dissertação, única e exclusivamente, nos métodos estético-recepcionais, mas, de amparados pelos estudos hermenêuticos, sobretudo os formulados por Jauss, constituir um cenário possível para a obra de Guimarães Rosa, considerando suas várias interpretações e sua importância para a afirmação do caráter vanguardista atribuído ao seu legado, em especial à "Uma estória de amor". Durante a realização da festa que marcará a inauguração da fazenda, os muito contadores e cantadores chegam à Samarra (propriedade de Federico Freire, patrão de Manuelzão) com a missão de contar narrativas e cantigas que conduzirão o velho vaqueiro a um raro momento de parada dos seus afazeres na fazenda, levando-o a fazer parte da celebração de sua festa. Com vista a realizar o objetivo proposto nesta Dissertação, sua divisão estrutura-se na construção de três capítulos, sendo cada um, subdividido em duas partes. Tal divisão há de servir ao alcance das questões, conclusões e possibilidades interpretativas sobre "Uma estória de amor". Assim é que, já no primeiro capítulo do texto, explorar-se-á a recepção crítica de "Uma estória de amor", bem como seu caráter vanguardista, tomando como exemplo a Literatura oral, que torna a novela de Guimarães Rosa objeto mais do que suficiente aos estudos propostos por Jauss. No segundo capítulo, dissertar-se-á sobre o amor, segundo a discussão empreendida por Derrida acerca do phármakon, teorizado em A farmácia de Platão (1991), como recorrência, ao mesmo tempo, desencadeadora de um veneno e de um poder curativo, que atribuem, ao protagonista da novela em questão, o papel do ouvinte ainda capaz de se emocionar e surpreender-se com a simples audição de relatos, aparentemente tão ingênuos sobre estórias adquiridas e perpassadas ao longo dos anos pela oralidade. No capítulo final, intenta-se realizar uma análise de alguns cantos, e, especificamente, de três narrativas condicionadas em "Uma estória de amor", dialogando com leituras mais recentes da obra (Sandra Vasconcelos, em Puras Misturas [1997], por exemplo), para demonstrar a importância do relato transmitido pelas várias gerações que procedem à narrativa original, as quais, indiferente às mudanças de rumo constantes nesses possíveis textos, muitas vezes, parecem discordar do original.

Energetic and economic analysis of a Brazilian compact cogeneration system: Comparison between natural gas and biogas

Cogeneration may be defined as the simultaneous production of electric power and useful heat from the burning of a single fuel. This technique of combined heat and power production has been applied in both the industrial and tertiary sectors. It has been mainly used because of its overall efficiency, and the guarantee of electricity with a low level of environmental impact. The compact cogeneration systems using internal combustion engine as prime movers are thoroughly applied because of the good relationship among cost and benefit obtained in such devices. The cogeneration system of this study consists of an internal combustion engine using natural gas or biogas as fuel, combined with two heat exchangers and an absorption chiller utilising water-ammonia as working mixture. This work presents an energetic and economic comparison between natural gas and biogas as fuel used for the system proposed. The results are useful to identify the feasible applications for this system, such as residential sector in isolated areas, hotels, universities etc. (C) 2014 Elsevier Ltd. All rights reserved.

A intersemiose texto-história-cinema na minissérie ROMA da HBO

From August 2005 to March 2007, the two seasons (with 12 and 10 episodes respectively) of the award winning miniseries HBO‟s ROME were aired by the Home Box Office (HBO) channel. With screenplay signed by various writers and directors, the TV series was a coproduction of HBO (USA) and BBC (UK) with support from RAI (Italy), and the show was filmed in multiple locations, but mainly in Cinecittà Film Studios in Rome, very famous for having been headquarters also for Federico Fellini‟s movies. In the first season, the miniseries depicts the conquest of Gaul, made by the military genius of Gaius Julius Caesar, and the political trajectory that made him accumulate power to such an extent that this divided Roman citizens into two factions, one supporting and the other opposing him, the latter focused mainly on the historic figure of General Gnaeus Pompey Magnus. The second season shows the period of civil war following the assassination of Caesar, and the future rise to power of his nephew, adopted son and sole heir, Gaius Octavian Augustus, who was destined to overcome his rivals as well as their allies in the triumvirate that had been formed to pursue and punish Caesar‟s assassins. These facts are well known and usually crowd the mind and imagination of every minimally educated person. The HBO series broke new ground not only for the talent of its writers, directors and actors, not only for its visual effects and locations nor for the vibrancy and grandeur of historical scenes – after all, “historical movies” in general do the same – but it has done so also by the (re)construction of historical events from the perspective of a pair of protagonists of whom too little is known: the centurions Titus Pullo and Lucius Vorenus, who are the only low-rank soldiers mentioned by Caesar in his book Commentaries on the Gallic War (Commentarii de Bello Gallico V.44). Thus, the fictionalization of events also took into account several Roman civilization data which were scattered through historical sources and also those that belong to the modern knowledge of material culture, resulting in a TV series whose filmic aesthetics has rare beauty and creativity. From the survey of textual, historical and cultural data put together in this film, as well as the distance featuring the creative space in the dimension of the gap between them, this paper aims to highlight two pivotal moments of visual and narrative strategies of the show: the opening credits footage and the final scenes of the first season of HBO's Rome.

Exploring the virome of diseased horses

Metagenomics was used to characterize viral genomes in clinical specimens of horses with various organ-specific diseases of unknown aetiology. A novel parvovirus as well as a previously described hepacivirus closely related to human hepatitis C virus and equid herpesvirus 2 were identified in the cerebrospinal fluid of horses with neurological signs. Four co-infecting picobirnaviruses, including an unusual genome with fused RNA segments, and a divergent anellovirus were found in the plasma of two febrile horses. A novel cyclovirus genome was characterized from the nasal secretion of another febrile animal. Lastly, a small circular DNA genome with a Rep gene, from a virus we called kirkovirus, was identified in the liver and spleen of a horse with fatal idiopathic hepatopathy. This study expands the number of viruses found in horses, and characterizes their genomes to assist future epidemiological studies of their transmission and potential association with various equine diseases.

Poe tornado fellini: adaptação literária no cinema autoral

The purpose of this article is to assess Federico Fellini’s adaptation of an Edgar Allan Poe story for the screen. The film “Spirits of the Dead” is Fellini’s adaptation of Poe’s story “Never Bet the Devil your Head”, but it is very far from being a faithful rendering. The “infidelity” of the Italian film director to the American writer occurred in the context of the enormous prestige enjoyed by what was known as “authorism”, a phase which the film industry was going through at the end of the 1960s, whereby great value was placed on the aesthetic idiosyncrasies of individual film directors.

Electric consumption in SHSs in rural communities of brazil and Peru and recommendations for sizing

The lack of data records of electric power consumption of smallphotovoltaic home systems, independently of the method used for sizing them, drives to consider the demand as a constant. However, the existing data reveal the variability of the consumption due to the influences of some social, cultural and psychosocial aspects of the human groups. This paper presents records of consumption data obtainedfrom several solar home systems (SHSs) in Brazil and Peru, and it discusses about the Gamma distribution function that can express to a great extent the behaviour of the demand. By this analysis it was verified that `a lot of people consume little and few people consume a lot`. In that sense, a few recommendations for sizing procedures that can be useful in the implantation of extensive programmes of rural electrification by SHSs are presented.
