Thema: Lateinamerika – ein Sub-Kontinent scheint im Windschatten der Weltpolitik zu stehen. Doch südlich des Rio Grande steht die Zeit nicht still – ganz im Gegenteil! Hier sind Prozesse im Gange, die oft einmalig, manchmal auch wegweisend sind, jedoch stets zum Nachdenken anregen. Die sehr verschiedenen Rollen, die das Militär in den politischen Systemen dieser Länder gespielt hat und heute spielt, wird von lateinamerikanischen und deutschen Autoren diskutiert. Dabei geht es um regionale Sicherheit im 21. Jahrhundert, aber auch um differenzierte Blicke in die Geschichte. Statistiken bieten einen guten Überblick über das Militärische, und Buchbesprechungen zum Politischen runden den Schwerpunkt dieses Winterheftes ab. Streitplatz: Rot-Grün ist beendet, Bilanz wird gezogen. Dies nicht nur bei den Finanzen, sondern auch in der Außenpolitik. Wie fällt diese im Kapitel „Ostpolitik“ aus? Die Antworten werden sicherlich kontrovers sein. Schwarz-Rot hat begonnen. Auch für die neue Regierung wird das Verhältnis zu den östlichen Nachbarn zur einer Herausforderung, gleich ob zu Prag, Warschau, Kiew oder Moskau. Wie diese Beziehungen gestaltet werden sollen, ist auch umstritten. Jochen Franzke bilanziert kritisch die Ostpolitik der letzten Jahre und plädiert für einen konzeptionellen Wechsel. Welt- Trends startet mit diesem Beitrag eine neue Debatte zur deutschen Außenpolitik.

Die 1880er Jahre waren der Beginn einer massiven europäischen Einwanderung nach Argentinien. In dieser Arbeit werden kulturelle, politische, wirtschaftliche und demographische Veränderungen für das Land untersucht und welche Auswirkungen diese auf das Selbstverständnis der argentinischen Intellektuellen und die argentinische Kultur hatten. Die leitende Frage wird sein, wie eine kulturelle und nationale Identität in Zeiten der massiven Einwanderungswellen im Untersuchungszeitraum entstehen konnte. Dabei wird die politisch-historische Entwicklung, d.h. die Konstitution einer nationalen Identität, erörtert: Ist Argentinien mit der Unabhängigkeit im Jahre 1810 tatsächlich wirtschaftlich und politisch eigenständig geworden ist? Durch Balibars Nationenbegriff wird verifiziert werden, dass sich das Land erst im Untersuchungszeitraum zu einer Nation wandelte, das jedoch eine fragile Identität besaß. Zum anderen werden anhand des Assmannschen Konzeptes des Kulturellen Gedächtnisses die Erinnerungskultur und die Ausbildung eines kulturellen Gedächtnisses der argentinischen Intellektuellen erörtert. Ein einheitliches Bewusstsein für nationale und kulturelle Werte war nicht existent. Dies spiegelte sich in der Literatur, in der Kunst und im Theater im Untersuchungszeitraum wider. Im Laufe der massiven Einwanderungsströme entstand eine neue Gesellschaft, nichtsdestotrotz wurden kulturelle Neuerungen der Einwanderer kaum in die kulturelle Identität integriert. Nicht nur die eigene Kultur wurde verklärt gesehen, sondern auch die europäische Kultur überformt und selektiert, dessen Abbild in die argentinische Kultur integriert wurde. Durch diese Arbeit sollen Erkenntnisse aus historischer Sicht gewonnen werden, die bis heute Argentinien und den gesamten südamerikanischen Kontinent prägen: die Frage nach der Identität, die in Zeiten massiver Immigration verstärkt gestellt wurde. / In Argentina the 1880s mark the beginning of a huge flow of European immigrants to the country. This article deals with the cultural, political, economic and demographic changes and which consequences these had for the identity of Argentinian intellectuals and for Argentinian culture. The article also focuses on answering the prevalent question of how a cultural and national identity could develope in times of massive immigration during this era. The author attempts at examining the political development within its historic context, which gives key clues about the constitution of a national identity: Did Agentina really become self-sufficient politically and economically with its independence in 1810? Balibar's definition of nations confirms that the country of Argentina only developed into a nation during the examined time period of the 1880s, although with a yet fragile identity. The concept of Assmann helps to identify the collective memory and cultural identity of Argentinian intellectuals. Prior to the migration flow examined in this article, a homogeneous consciousness of national and cultural values did not exist. Literature, art and theatre during the examined era all reflected the lack thereof. During the migration flow a new society developed, in which, nevertheless, new cultural values of the immigrants were barely absorbed. Not only did one view Argentinian values in an idealized way, but one also saw selected parts of European culture as ideals, which were integrated into Argentinian culture as they were understood. The findings drawn from a historic context in this article will provide valuable information about questions of identity that, especially during migration flows, continue to be of interest in Argentina and the whole South American continent until today.

<p>The tropics are a significant source of heat and moisture export, which drive global circulation patterns, thus it is vital to systematically understand the land, ocean and sedimentological interactions within the tropics. The Brazilian continental margin is an ideal region to characterize the tropics due to its unique local oceanography and proximity to the atmospheric engine that is the Amazon Basin. A combination of: 1) terrestrial organics and hydrology; 2) oceanographic temperature, isotopic composition, and salinity and 3) early diagenesis and geochemistry of sedimentary interstitial water and methane hydrate, provide a detailed understanding of the primary constituents that influence the South American tropics.</p><p>Sedimentological, organic and paleoceanographic reconstructions of the Amazon Basin, Brazilian Nordeste, and western equatorial Atlantic have been undertaken on two sediment cores located on the Brazilian continental slope representing 30 and 110 ka, respectively. High-resolution XRF analyses of Fe, Ti, K and Ca are used to define the sedimentological history of the Amazon Basin and northern Nordeste. Here we present elemental ratios of Ti/Ca and Fe/K, in addition to magnetic susceptibility, to determine variability in Amazon Basin and Nordeste hydrology. Bulk organic proxies d13C and d15N of sedimentary organic carbon are used to define the organic history of the Amazon Basin. Peaks in Ti/Ca and Fe/K ratios largely correlate in both the Amazon Basin and in the Nordeste Record. These excursions correlate with commonly modeled global slowdown of the Atlantic meridional overturning circulation (AMOC) during increased northern hemisphere glaciation. Differences in the Fe/K and Ti/Ca records suggest periods of increased chemical weathering independent of precipitation driven sediment discharge in the Brazilian Nordeste. Bulk organic geochemistry indicates the vegetative history of the Amazon Basin has been relatively stable during the late Quaternary.</p><p>High-­resolution stable oxygen isotopic analysis and Mg/Ca paleothermometry undertaken on the near-­surface-dwelling planktic foraminiferal species Globierinoides ruber provide a picture of paleoceanographic forcings in the western equatorial Atlantic. The Nordeste core exhibits a rapid warming of ~3.5ºC between the last glacial maximum and the early Holocene. Furthermore, in almost all cases during the last glacial stage, there was a 0.5 to 2ºC warming of the western equatorial Atlantic during the periods of high Ti/Ca ratios that correlate with slowdown of AMOC. Thus, as observed in some previous studies, the western equatorial Atlantic was warm and the adjacent southern tropical continent was wet coincident with increased glaciation in the high latitude northern hemisphere.</p><p>Interstitial pore waters were analyzed from the Amazon Fan and Brazilian continental slope to determine early diagenesis, methane hydrate potential and its geographic variability. Interstitial waters were measured for total Mg, Ca, SO4, alkalinity, Cl, and d18O, combined with seismic bottom simulating reflectors (BSRs) to investigate early diagenesis. Interpolated maps of sulfate reduction, sedimentation rate and maximum alkalinity were produced to examine geographic variability in early diagenesis and methane hydrates. Inorganic precipitation of calcium and magnesium, likely via dolomite and siderite, correlates with a decrease in alkalinity through inorganic carbonate precipitation and methanogenesis, but alternatively increases through redox pathways, specifically sulfate reduction.</p><p>Through multiple lines of evidence it is likely that there is extensive methane hydrate occurrence on the Amazon continental shelf. A combination of: 1) A rapid linear decline in sulfate at an unusually shallow depth; 2) Uncommonly high sedimentation rates and terrestrial organic carbon input; 3) Significant variability in what should be conservative chloride concentrations; 4) Large variability in interstitial oxygen isotopes; 5) Widespread occurrence of BSRs provide substantial support for the presence of methane hydrates. Sulfate reduction rates are lowest along the main Amazon channel, with highest values distal of the main channel. Sedimentation rates are relatively low on the continental shelf and surrounding the main channel and highest toward the distal end of the main channel. Sulfate reduction rates provide key insights to the potential geographic variability of methanogenesis and methane hydrate formation. Given the tremendous influx of sediment from the Amazon River, this region is prone to massive sediment failures, subsequent release of methane hydrates, as well as significant potential for natural gas hydrates.</p> / Dissertation

During the years 2000-2002, the Republic of Argentina experienced one of the most, if not the most, devastating social/political/economic crisis ever seen. President Fernando de la Rua, elected in 1999, was forced to resign on December 20th, 2001, after several months of protests, public demonstrations, and a colossal economic recession. During the crisis, the media played a vital role, they told people not only what issues to think about but also what to think about them. This study analyzed the newspapers role during the crisis using the Agenda-Setting Theory as the research foundation.

A dietary reconstruction was performed in order to understand changing prehistoric subsistence patterns in the Central Andean geographical area of the Argentine Cuyo that includes the provinces of San Juan and Mendoza. Archaeologically, the Cuyo is also known as a boundary between Andean agriculturalists and the foragers of Patagonia. One hypothesis being tested is whether this area was one of the last South American cultural groups to convert to maize cultivation, probably around 2000 BP. The process of stable isotope analysis is used to reconstruct the diets of individuals, as it reveals the relative proportions of C3 and C4 plants and the contribution of aquatic resources to otherwise terrestrial diets, as well as variations in trophic level of the foods consumed. In this study the bones, teeth, hair, and flesh from 45 individuals were tested to address specifically total and protein diets, as well as seasonal variation and changes between childhood and adulthood. This process, when used in combination with previous analyses, such as midden or faunal analysis, allows researchers to evaluate the results of those previous studies, and thus compose a more thorough reconstruction of the lifestyles of a prehistoric culture. Information garnered from this study indicates that the times of dietary transition were variable, with seasonal patterns becoming more stable over long periods. Furthermore, some members of the study population demonstrate the existence of nutritional stress indicators, such as dental caries, that can be viewed in relation to the dietary shifts that may have been a cultural adaptation to the environment of the Cuyo. Overall, this study shows the early adoption of maize agriculture in central western Argentina and recommends future studies that analyze the relationships between agriculture, diet, and nutrition in the New World.

This study is an investigation of late prehistoric irrigation agriculture in North Coastal Peru. There has been much debate over the significance of irrigated agriculture to the development of indigenous civilization on the North Coast of Peru. Yet, in spite of the many references to prehistoric North Coast irrigation, only recently is information regarding the technology and functioning of the prehistoric systems becoming available. Little, however, is yet known about the extent of the prehistoric irrigation systems preserved on the North Coast. It is the intent of this study to present a summary of our present knowledge regarding these aspects of North Coast irrigation agriculture, to suggest methods and avenues for continued research, and to propose several specific hypotheses with regard to late prehistoric agricultural technology and environmental exploitation. / text
