Biopolítica y gran relato nacional: presencia espectral del mundo aborigen en tres novelas de la selva (Estudios)

Escritas durante la primera mitad del siglo XX, Canaima, La vorágine, y Sangama son tres novelas de la selva en las cuales aparece una representación del mundo indígena del Amazonas o del Orinoco. Se ha repetido que se trataba de novelas progresistas, que encerraban una crítica del sistema social de la época, y más particularmente del genocidio acarreado por la explotación del caucho durante el “ciclo da borracha”. Sin embargo estas ficciones nos proporcionan un enfoque ambiguo de la realidad indígena. Una visión impregnada por las mismas concepciones del siglo XIX que favorecieron los excesos, maltratos y masacres que dichas novelas pretenden denunciar. Este ensayo se propone analizar la matriz científica de estas representaciones, insistiendo en el paradigma racialista decimónico, derivado de la teoría evolucionista y de la ideología del progreso. Los indios de las ficciones se desplazan como fantasmas en un universo mágico, embrujado, o infernal que carece de realidad. Este “flor” romántico es la proyección literaria de una estrategia biopolítica que se da en las sociedades de la época: la cuestión gira en torno a la construcción del pueblo nacional. Los “aparecidos” del espacio novelesco son un momento de unas estrategias discursivas más globales: se trata de construir una homegeneidad nacional a partir de una etnicidad ficticia que requiere el rechazo del “otro atrasado”. El espectro es la huella o el testigo de esta violencia fundadora.

La emergencia del intelectual en América Latina y el espacio público: el caso de Alfonso Reyes, 1927-1939 (Debates)

This article is a case study of the emergence of the intellectual in Spanish American: the trajectory of Alfonso Reyes. In Latin America modernity and the beginnings of the 20th Century contributed to circumstances and historical processes that permitted the 19th Century literates to progressively transform into intellectual: to be exact a ‘transitional intellectual’. This study looks at some of the dynamics that validated the intellectual as a new social actor during the period studied. The public visibility as it was never before, placed thinkers, and the use of means of communication of the time and the cultural elements like books and magazines, allowing that they be turned into public figures and to obtain some of their objectives.

The Mersey Basin: an historical assessment of water quality from an anecdotal perspective

The freshwaters of the Mersey Basin have been seriously polluted for over 200 years. Anecdotal evidence suggests that the water quality was relatively clean before the start of the Industrial Revolution. The development of the cotton and chemical industries increased the pollution load to rivers, and consequently a decline in biota supported by the water was observed. Industrial prosperity led to a rapid population increase and an increase in domestic effluent. Poor treatment of this waste meant that it was a significant pollutant. As industry intensified during the 19th century, the mix of pollutants grew more complex. Eventually, in the 1980s, the government acknowledged the problem and more effort was made to improve the water quality. Knowledge of social and economic history, as well as anecdotal evidence, has been used in this paper to extrapolate the changes in water quality that occurred. (C) 2003 Elsevier Science B.V.

Onset of recent rapid sea-level rise in the western Atlantic Ocean

A high-resolution record of sea-level change spanning the past 1000 years is derived from foraminiferal and chronological analyses of a 2m thick salt-marsh peat sequence at Chezzetcook, Nova Scotia, Canada. Former mean tide level positions are reconstructed with a precision of +/- 0.055 in using a transfer function derived from distributions of modern salt-marsh foraminifera. Our age model for the core section older than 300 years is based on 19 AMS C-14 ages and takes into account the individual probability distributions of calibrated radiocarbon ages. The past 300 years is dated by pollen and the isotopes Pb-206, Pb-207, Pb-210, Cs-137 and Am-241. Between AD 1000 and AD 1800, relative sea level rose at a mean rate of 17cm per century. Apparent pre-industrial rises of sea level dated at AD 1500-1550 and AD 1700-1800 cannot be clearly distinguished when radiocarbon age errors are taken into account. Furthermore, they may be an artefact of fluctuations in atmospheric C-14 production. In the 19th century sea level rose at a mean rate of 1.6mm/yr. Between AD 1900 and AD 1920, sea-level rise accelerated to the modern mean rate of 3.2mm/yr. This acceleration corresponds in time with global temperature rise and may therefore be associated with recent global warming. (c) 2005 Elsevier Ltd. All rights reserved.

Stable isotope evidence for 1500 years of human diet at the city of York, UK

We present here the results of a large-scale diachronic palaeodietary (carbon and nitrogen isotopic measurements of bone collagen) study of humans and animals from a single site, the city of York (U.K.) dating from the Roman period to the early 19th century The human sample comprises 313 burials from the cemeteries of Trentholme Drive and Blossom Street (Roman), Belle Vue House (Anglo-Saxon), Fishergate (High and Later Medieval), and All Saints, Pavement (Later and Post-Medieval). In addition, 145 samples of mammal, fish and bird bone from the sites of Tanner Row and Fishergate were analyzed. The isotope data suggest dietary variation between all archaeological periods, although the most significant change was the introduction of significant quantities of marine foods in the Medieval periods. These are first evident in the diet of a small group of individuals from the High Medieval cemetery at Fishergate, although they were consumed almost universally in the following periods. The human isotope values are also remarkable due to unusually elevated delta N-15 ratios that are not sufficiently explained by the comparably small enrichment in C-13 that accompanies them. We discuss the possible reasons behind this and the archaeological significance of the data set.
