Diversidade cultural e democracia

Trata-se de reflectir sobre a livre convivência multicultural, em todas as suas formas, mesmo as socialmente mais intensas, num memso espaço públlico, onde o Estado laico garanta diversidade, igualdade e liberdade de ritos sociais no plano da sociedade civil. Esta é uma questão vital em tempos de globalização e de migração generalizada de pessoas, culturas e processos numa só sociedade de fenómenos intensos de miscigenação cultural, nos seus diversos patamares. Pode uma sociedade democrática garantir equilíbrios, igualdade e liberdade lá onde convivem visões de mundo e ritos sociais aparentemente contrastantes? De que modo? Com que instrumentos políticos é possível regular esta multiculturalidade? E nesta vasta multiculturalidade existirá um mesmo fio condutor que a remeta à unicidade fundamental da existência humana nos seus nexos vitais primordiais?

Museos y normalización política en la España postfranquista

Que España ha arrastrado un atraso secular respecto a los países de su entorno es un lugar común a la hora de caracterizar un desarrollo histórico singular. Que ese atraso se remonta, probablemente, al momento en que comienza el declive del imperio colonial español es una suposición a la que cabría hacer múltiples matizaciones. Que las consecuencias de ese atraso se vieron agravadas en el siglo XX, hasta el punto de suscitar la frase de Unamuno –en la que juegan a partes iguales el sarcasmo y la reivindicación de lo singular, teñido todo ello de un pesimismo muy del gusto tenebrista-, es algo que cualquier observador imparcial –o cualquiera que haya vivido un buen trecho de ese siglo XX- jamás pondría en duda. Máxime, quien conozca el impacto de la sublevación militar de 1936 que condujo, tras una cruenta guerra civil (1936-39), al triunfo del General Franco y a la instauración de una dictadura que habría de sobrevivir durante varias décadas.

A laicidade do estado brasileiro e os feriados nacionais

A laicidade do Estado brasileiro, presente desde a primeira Constituição republicana, sofreu variações em sua práxis ao longo da história. A relação entre Igreja e Estado nunca foi de total separação no Brasil e um dos fatores responsáveis por isso é a religiosidade popular, com um sincretismo pouco visto em outras nações do mundo. Diante disso e da tradição cristã católica, imiscuída no povo brasileiro desde os primórdios de sua colonização, fizeram com que feriados de cunho religioso permanecessem no calendário oficial do país, a despeito de ser um Estado laico. As razões que levaram a isso só podem ser compreendidas com uma análise da evolução do conceito de laicidade nos textos constitucionais do Brasil independente e da influência dos costumes no ordenamento jurídico pátrio.

Clave del relato histórico de Alfredo Pareja Diezcanseco: herencia colonial, Revolución liberal y mestizaje (Del Historiador y el Ensayista)

El autor analiza la perspectiva de Pareja sobre los problemas y logros del país hasta los años cincuenta, argumenta que es la de un republicano laico, socialista, modernizador y guayaquileño. Algunas valoraciones de Pareja se inscriben en el contexto de la inexistencia de un campo de saber historiográfico constituido en el Ecuador de esos años. Su perspectiva de la conquista tiene elementos de una visión hispanista del devenir histórico, que quiere reconciliarse con la búsqueda de una modernidad no alcanzada y afanosamente deseada. Respecto de la independencia, la libertad no se consagró en 1822, sino recién en 1895, con la Revolución liberal, que llevaría a la modernización del Estado, en ella jugaría un rol central el mestizo como actor colectivo. Finalmente, Pareja atribuye al mestizaje la posibilidad de incorporación del país a la dinámica civilizadora, de puesta al día con los valores de la democracia y el progreso.

Alfredo Pareja Diezcanseco y su sentido de la historia (Del Historiador y el Ensayista)

El autor revisa las indagaciones de Alfredo Pareja sobre la historia y la identidad, las cuales responden a una idea de nación mestiza. En la narrativa de Pareja, resalta un afán mesiánico, es laica, secular, y condicionada por una manera de pensar, organizar y narrar la Historia: desde las ideas liberales del siglo XIX y algunas consideraciones del socialismo. El énfasis en lo auténtico y lo propio conduce a rechazar, sin mayores consideraciones, lo «moderno» y lo extranjero. Así, en La hoguera bárbara presenta la cuestión religiosa solo desde la perspectiva oficial y laica, dando poco espacio a aquella de la Iglesia, o a la de dos obispos extranjeros, ambos «rebeldes»: Schumacher y Masiá. En cuanto a la visión de la historia en Pareja, sostiene que en La hoguera .. "" como en el Compendio para segunda enseñanza, se revelaría un sentido de ella al estilo de un BiJdungsroman a nivel de nación, conducido por las mencionadas ideas del liberalismo decimonónico y de algunas aspiraciones socialistas.

La «destrucción creadora» en dos cuentos de Juan Carlos Onetti (Crítica)

Si bien con la Edad Moderna el lenguaje dejó de ser un instrumento sagrado, desde fines del siglo XIX e inicios del XX se revela el carácter arbitrario del signo lingüístico, reafirmando el carácter secular de la palabra. La autora plantea que Juan Carlos Onetti reflexiona en su obra sobre el carácter y las funciones del lenguaje en el texto, desacralizándolo, alejándose de las pretensiones totalizadoras de la crítica. En los dos cuentos de Onetti («El posible Baldi» y «Luna llena») los personajes escriben. En el primero, Baldi remarca el carácter arbitrario de toda ficción (esta vez, de una ficción sobre sí mismo): destruye la tentación de convertirse en un héroe, al presentarse como un proxéneta y traficante, busca provocar el asco en una literata romántica, que ha sido seducida por la palabra, sin conseguirlo. El personaje del segundo cuento, Carmencita, siente que ha fracasado como escritora, y que su cuerpo envejecido la somete al riesgo del ridículo. A diferencia de Baldi, no se atreve a reír de esta posibilidad ni del asco, muere atrapada en una ficción que no deja de ser romántica. Se reflexiona sobre la finalidad del lenguaje en la «realidad» y en las ficciones que crean estos seres de ficción.

La espiritualidad mundana en Cuenca a inicios del siglo XVIII. El caso de Martina Catalina de Barzallo (Estudios)

El ensayo examina el proceso judicial de una monja en Cuenca, a inicios del siglo XVIII, que buscaba regresar a la ""vida mundana"" y anular su profesión y hábito. Este caso permite mostrar la mentalidad barroca, acercarse a la construcción cultural del cuerpo y a la situación de las mujeres. A partir de los fragmentos disponibles del juicio, el artículo sugiere que Martina Catalina de Barzallo reivindicó el retomo a la vida mundana y el rechazo a las prácticas coercitivas propias de la vida monástica.

Estéticas de frontera en el contexto colombiano

En esta tesis se investiga cómo son posibles las estéticas decoloniales en el contexto colombiano. El argumento central sustenta que estas estéticas parten de una doble operación en que se revela la acción de la colonialidad estética, en el mismo momento en que prácticas decoloniales irrumpen desde la aiesthesis colonizada, esto es, desde la frontera ontológica construida por la colonialidad del poder. En este propósito se hizo necesario indagar cómo surge la estética moderna/colonial como una dimensión constitutiva de la modernidad/colonialidad, primero como teo-estética en los siglos XVI-XVII y luego como egoestética secular en la segunda modernidad (a partir del siglo XVIII); la segunda se denomina simplemente ‘estética’ y su particular objeto de estudio será el arte. Nuestro objetivo, sin embargo, no es hacer una historia de las ideas estéticas, sino visibilizar un conjunto de prácticas artísticas en su contexto, dentro y fuera del denominado campo del arte en Colombia: tres obras del artista José Alejandro Restrepo, la práctica de las estatuas vivas urbanas o estatuismo, y el cine documental de Marta Rodríguez. A partir de ese conjunto de prácticas y en diálogo colaborativo con sus agentes, se visibilizan las estéticas decoloniales, adquiriendo distintas formas, de acuerdo con las circunstancias particulares de originación y aparición. Esas estéticas, con sus maneras de sentir, pensar y hacer el mundo de otro modo, convergen con su heterogeneidad en el horizonte amplio de la decolonialidad transmoderna e intercultural, en sus dimensiones epistémica, política, ética, estética, del cuerpo y de la naturaleza. Las estéticas decoloniales son parte de una opción que reconoce la validez de otras opciones como la re-occidentalización, la des-occidentalización o la reconfiguración de la izquierda. Con esta tesis, estructurada en cuatro capítulos, pretendemos realizar un aporte, en la reflexión filosófica y teórica, al fortalecimiento del campo epistémico, ético y político de la decolonialidad. Lo hacemos con el intento de desjerarquizar la teoría estética hegemónica, buscando poner en diálogo horizontal, y en un mismo plano de validez, una diversidad de prácticas creativas en que se puede ver tanto la marca de la colonialidad como la tensión propia de un desprendimiento de la misma, si bien es cierto con intensidades diferentes y desde lugares distintos.

Ecuador

Ecuador’s total population numbers some 15,682,792 inhabitants, and includes 14 nationalities accounting for around 1,100,000 people, all joined together in a series of local, regional and national organisations. 60.3% of the Andean Kichwa live in six provinces in the Central-North Mountains; 24.1% live in the Amazon region and belong to ten nationalities; 7.3% live in the Southern Mountains; and the remaining 8.3% live in the Coastal region and the Galapagos Islands. 78.5% still live in rural areas and 21.5% in urban areas. The current Constitution of the Republic recognises the country as a “…constitutional state of law and social justice, democratic, sovereign, independent, unitary, intercultural, multinational and secular���. Over the last five years, the country has undergone a series of political and institutional reforms. At the same time, however, enforcing and guaranteeing the collective rights recognised in the Constitution has become a challenge to the process, and a permanent point of disagreement between the government, headed by the economist Rafael Correa, and the indigenous social organisations. The government’s economic action has been largely marked by an opening up of the extractive industries - oil, copper and gold - to foreign investment, either of Chinese or Belarussian origin, or from other Latin American countries such as Brazil, Chile or Argentina. This has resulted in risk to and impacts on the territorial and cultural integrity of various indigenous peoples, and an uncertainty created around the true validity of the broad collective rights enshrined in the Constitution.

Historical reconstruction of the Atlantic Meridional Overturning Circulation from the ECMWF operational ocean reanalysis

A reconstruction of the Atlantic Meridional Overturning Circulation (MOC) for the period 1959–2006 has been derived from the ECMWF operational ocean reanalysis. The reconstruction shows a wide range of time-variability, including a downward trend. At 26N, both the MOC intensity and changes in its vertical structure are in good agreement with previous estimates based on trans-Atlantic surveys. At 50N, the MOC and strength of the subpolar gyre are correlated at interannual time scales, but show opposite secular trends. Heat transport variability is highly correlated with the MOC but shows a smaller trend due to the warming of the upper ocean, which partially compensates for the weakening of the circulation. Results from sensitivity experiments show that although the time-varying upper boundary forcing provides useful MOC information, the sequential assimilation of ocean data further improves the MOC estimation by increasing both the mean and the time variability.

Evaluating the efficacy of planktonic foraminifer calcite and 18O data for sea surface temperature reconstruction for the Late Miocene

This study examines the efficacy of published δ18O data from the calcite of Late Miocene surface dwelling planktonic foraminifer shells, for sea surface temperature estimates for the pre-Quaternary. The data are from 33 Late Miocene (Messinian) marine sites from a modern latitudinal gradient of 64°N to 48°S. They give estimates of SSTs in the tropics/subtropics (to 30°N and S) that are mostly cooler than present. Possible causes of this temperature discrepancy are ecological factors (e.g. calcification of shells at levels below the ocean mixed layer), taphonomic effects (e.g. diagenesis or dissolution), inaccurate estimation of Late Miocene seawater oxygen isotope composition, or a real Late Miocene cool climate. The scale of apparent cooling in the tropics suggests that the SST signal of the foraminifer calcite has been reset, at least in part, by early diagenetic calcite with higher δ18O, formed in the foraminifer shells in cool sea bottom pore waters, probably coupled with the effects of calcite formed below the mixed layer during the life of the foraminifera. This hypothesis is supported by the markedly cooler SST estimates from low latitudes—in some cases more than 9 °C cooler than present—where the gradients of temperature and the δ18O composition of seawater between sea surface and sea bottom are most marked, and where ocean surface stratification is high. At higher latitudes, particularly N and S of 30°, the temperature signal is still cooler, though maximum temperature estimates overlap with modern SSTs N and S of 40°. Comparison of SST estimates for the Late Miocene from alkenone unsaturation analysis from the eastern tropical Atlantic at Ocean Drilling Program (ODP) Site 958—which suggest a warmer sea surface by 2–4 °C, with estimates from oxygen isotopes at Deep Sea Drilling Project (DSDP) Site 366 and ODP Site 959, indicating cooler than present SSTs, also suggest a significant impact on the δ18O signal. Nevertheless, much of the original SST variation is clearly preserved in the primary calcite formed in the mixed layer, and records secular and temporal oceanographic changes at the sea surface, such as movement of the Antarctic Polar Front in the Southern Ocean. Cooler SSTs in the tropics and sub-tropics are also consistent with the Late Miocene latitude reduction in the coral reef belt and with interrupted reef growth on the Queensland Plateau of eastern Australia, though it is not possible to quantify absolute SSTs with the existing oxygen isotope data. Reconstruction of an accurate global SST dataset for Neogene time-slices from the existing published DSDP/ODP isotope data, for use in general circulation models, may require a detailed re-assessment of taphonomy at many sites.

An eclectic morphostratigraphic model for the sedimentary response to Holocene sea-level rise in northwest Europe

The improved empirical understanding of silt facies in Holocene coastal sequences provided by such as diatom, foraminifera, ostracode and testate amoebae analysis, combined with insights from quantitative stratigraphic and hydraulic simulations, has led to an inclusive, integrated model for the palaeogeomorphology, stratigraphy, lithofacies and biofacies of northwest European Holocene coastal lowlands in relation to sea-level behaviour. The model covers two general circumstances and is empirically supported by a range of field studies in the Holocene deposits of a number of British estuaries, particularly, the Severn. Where deposition was continuous over periods of centuries to millennia, and sea level fluctuated about a rising trend, the succession consists of repeated cycles of silt and peat lithofacies and biofacies in which series of transgressive overlaps (submergence sequences) alternate with series of regressive overlaps (emergence sequences) in association with the waxing and waning of tidal creek networks. Environmental and sea-level change are closely coupled, and equilibrium and secular pattern is of the kind represented ideally by a closed limit cycle. In the second circumstance, characteristic of unstable wetland shores and generally affecting smaller areas, coastal erosion ensures that episodes of deposition in the high intertidal zone last no more than a few centuries. The typical response is a series of regressive overlaps (emergence sequence) in erosively based high mudflat and salt-marsh silts that record, commonly as annual banding, exceptionally high deposition rates and a state of strong disequilibrium. Environmental change, including creek development, and sea-level movement are uncoupled. Only if deposition proceeds for a sufficiently long period, so that marshes mature, are equilibrium and close coupling regained. (C) 2002 Elsevier Science B.V. All rights reserved.

Performance of the OPA/ARPEGE-T21 global ocean-atmosphere coupled model

The climatology of the OPA/ARPEGE-T21 coupled general circulation model (GCM) is presented. The atmosphere GCM has a T21 spectral truncation and the ocean GCM has a 2°×1.5° average resolution. A 50-year climatic simulation is performed using the OASIS coupler, without flux correction techniques. The mean state and seasonal cycle for the last 10 years of the experiment are described and compared to the corresponding uncoupled experiments and to climatology when available. The model reasonably simulates most of the basic features of the observed climate. Energy budgets and transports in the coupled system, of importance for climate studies, are assessed and prove to be within available estimates. After an adjustment phase of a few years, the model stabilizes around a mean state where the tropics are warm and resemble a permanent ENSO, the Southern Ocean warms and almost no sea-ice is left in the Southern Hemisphere. The atmospheric circulation becomes more zonal and symmetric with respect to the equator. Once those systematic errors are established, the model shows little secular drift, the small remaining trends being mainly associated to horizontal physics in the ocean GCM. The stability of the model is shown to be related to qualities already present in the uncoupled GCMs used, namely a balanced radiation budget at the top-of-the-atmosphere and a tight ocean thermocline.
