Antarctica was the last continent to be discovered in the early nineteenth century. In order to become acquainted with the process of incorporation of Antarctica to the scope of the capitalist system we have focused on particularity: i.e., specific economic and technological and ideological aspects of everyday life in sealer camps spread along the coastline of the South Shetland Islands. Archaeological research in Byers Peninsula–Livingston Island provides an approach to the mechanisms implemented to organize the first resource exploitation in these lands.  相似文献

We argue in this paper that Levantine rock art in the Spanish Mediterranean basin allows us to ‘map’ the economic landscape of its makers. Rock art would be the ‘monumental’ side of a dual process of landscape construction: on the one hand, rock art is the first ‘cultural’ action on the landscape beginning in the Early Neolithic; on the other hand, the first evidence of active modification of the Mediterranean vegetation comes from this period. But this evidence as well as other kinds of archaeological remains are still relatively scarce in the uplands; rock art is therefore the most complete type of evidence we can use to support an early use of the Mediterranean upland environment. We use statistical and geographical analysis, together with archaeological, ethnohistorical, and ethnographic sources and pollen data, in order to support the idea of early use and exploitation of the Mediterranean uplands since the Neolithic, and into contemporary times.  相似文献

Este artículo contribuye a destacar el capital simbólico que encarnó en la Colonia la vida de Catalina de San Juan, natural del reino del Gran Mogol e hija espiritual de la Compañía de Jesús. Si bien la autora profundiza en la figura hagiográfica de la beata y aclara algunos errores esbozados por la crítica, su aporte principal radica en las Actas de Cabildo de Puebla del siglo XVII. Estos documentos son prueba fehaciente de la concertada participación de las autoridades civiles en lo que se esperaba fuera el proceso testimonial para una pronta causa de beatificación. Aunque la Santa Sede no la canonizara, Catalina de San Juan fue proclamada santa por un pueblo que vio en ella los Prodigios de la Omnipotencia, glosados teatralmente por la pluma de sus confesores. La luz que muchos atestiguaron ver al final de sus días ilumina por siempre la historia novohispana con el misterio de su leyenda.  相似文献

In 1842, the Parisian editor Louis-Antoine Pagnerre published the Dictionnaire politique. This large volume was the manifesto of the French Republicans in opposition to the conservative governments of King Louis-Philippe under the July Monarchy. One of the most original aspects of the Dictionnaire resides in the attempt to link the doctrine of republicanism to political economy. It is the purpose of this paper to analyse the republican political economy presented in Pagnerre's dictionary. First, we detail the historical context in which it appeared, stressing on Pagnerre's biography and on the composition of the group of young republicans who wrote the main economic entries of the book. Second, we focus on the economic ideas about the political regulation of industrial phenomena and the solutions these Republicans imagined to solve the social question. Third, we conclude by attempting to summarize the main characteristics of this republican political economy and to appreciate its originality.  相似文献

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.  相似文献

The aim of this work was to detect imprints on soil properties from former Islamic land use (9th to 11th century) using a multi-method, soil-chemical approach. Four soil profiles (with buried horizons) found in the vicinities of former Islamic settlements in Sicily were analysed for phosphorus (total, organic and inorganic), nitrogen (total, NO3 and NH4+), carbon compounds (δ13C, lipids, polycyclic aromatic hydrocarbons (PAH) and functional groups), physical and chemical C-fractions and the state of soil weathering. Two soil profiles contained ceramic sherds from the Islamic period. Inorganic nitrogen forms, phosphorous and the PAH content indicated strong impacts from traditional agriculture and/or burning. Radiocarbon dating of soil organic carbon (SOC) fractions from buried horizons showed that distinct changes must have occurred during the Islamic epoch. The isotopic composition of SOC indicated that land use was probably different in earlier times. C4 plant cultivation was expected but surprisingly lipid analyses did not confirm this. A high amount of aliphates and low C/N ratio indicated a good, long-term SOC stabilisation under the native conditions combined with Islamic land use. The irrigation of the soils probably increased the production of weakly-crystalline Fe forms that helped to stabilise SOC.  相似文献

Regional policies seek to enable regions to increase their competitiveness and development, and as such one priority objective of activities financed by Structural Funds is higher employment, higher productivity and economic activity. How efficiently the regions apply the funds is a fundamental issue for the development and continuity of regional policies. We, therefore, consider that determining the efficiency of European regional policies is an issue of high importance, and this is the main aim of this study. We have considered it appropriate to use the available information to apply a mathematical technique known as data envelopment analysis, which allows us to calculate the technical efficiency and inefficiency of the Structural Funds applied in the Objective 1 regions for the period 2000–2006. Furthermore, we wish to determine if the regions have been more efficient in increasing their levels of employment or in increasing productivity. Our study applies this methodology along with other methods such as regression analysis, profit analysis and factorial analysis to determine the variation in the rate of unemployment and productivity in these European Regions. The study reveals that only eight regions are efficient, although none of them is in all the models run.  相似文献

Recent scholarship on vertical geographies has lead to a critical reexamination of the relationship between space and power. In this paper, I develop a vertical geographies approach in an unexplored context and with a less tested method: that of cave explorers and scientists in the field in Venezuela, from an ethnographic perspective. Ethnographic analysis of exploration in practice, viewed in relation to a multi-dimensional environment and the social dynamics, bodies, and technologies involved in traversing it, illustrates the ways vertical geographies are constructed and experienced. For the Venezuelan Speleological Society, a group dedicated to cave exploration and science since 1967, examining these geographies highlights culturally specific ways the tension between sports and science in speleology play out and how new members are socialized in the field. Specifically, attention to verticality highlights the role that age, masculinist heroics, and other embodied dimensions play in the construction of speleological geographies. More broadly, an ethnographic focus on exploration, with humans probing the earth's sinuous contours, guards against thinking of verticality abstractly—doing so risks simplifying and even misrepresenting multi-dimensional and processual engagements among humans, their technologies, and the environment.  相似文献
