The aim of this article is to shed light on the eighteenth-century Italian reflection on luxury and consumption in a comparative perspective, clarifying, on the one hand, the complex significance that it assumed and, on the other, the specificity of the Italian context, marked by the immense political value of the debate on the subject. In particular this objective will be pursued through the analysis of specific cases among the many offered by the Italian context and through different research strands. These are: the debate on the evaluation of luxury; the transition from the notion of luxury to that of consumption; and the discussion on luxury and consumption in the revolutionary context. This article intends to outline the particular contribution made by Italian thought, which conveyed a multifaceted discourse of social reform, critique and understanding built on more even foundations, and at the same time to clarify what contribution can be made to current historiography by the study of this theme within eighteenth-century Italy.  相似文献

High-resolution multi-archive studies have been promoted to reveal abrupt discontinuities that would express rapid social reactions (days to decades) to sudden exceptional geogenic phenomena (climatic, volcanic, tectonic, geomorphic, or cosmic). We expose here how we have adopted this approach for examining the causal linkages between a series of cultural discontinuities encountered through the cultural deposits of Da’de (Syria) and cosmic airbursts. Cosmic events, known to be rare, erratic, and unpredictable, are traced by exceptional debris that formed from aerosols when violently compressed during entry through the earth atmosphere of hypervelocity cosmic collider. They consist of singular organo-mineral materials in the form of volatile-rich hydrocarbon fuel with resistant metal-rich carbonaceous composites and colorful polymers. The archaeological sequence comprises Da’de phases 0 to III that represent a nearly continuous accumulation for 1,000 years during the Pre-pottery Neolithic period (ca. 9,900–8,900 years bp) and two short-term occupation phases during the pre-Halaf (Da’de IV) and early Bronze Age periods (Da’de V). Study of the exceptional debris in virgin soils and occupation deposits at Da’de has allowed to distinguish an intact debris assemblage that pulverized at the ground following an airburst (type 1 natural singular signal) with the ones that have been processed by humans (type 2 anthropic singular signal). Type 1 singular organo-mineral materials were found intact at the contact of the virgin soil with the earliest Pre-pottery Neolithic A (PPNA) occupation layers (Da’de phase 0, area [SB]), at the top part of the virgin soil with the PPNA occupation layers (Da’de phase Ia, area [B]) and just under the lower slabs of the EB III/IV burials (Da’de phase V, area [SB]). This has allowed to establish a strict contemporaneity between cosmic airbursts and remarkable historical events: initial settlement at phase 0, establishment of the magnificent communal building at phase 1, EBIII/IV cemetery after a long period of abandonment. Evidence for the collection of the singular materials (type 2) and meticulous processing of the related hydrocarbon fuel in occupation floors, earthen construction, coloring materials, and objects have been traced from the initial settlement (phase 0) through the successive cultural periods. This correlation has revealed a long-lasting transmission of the value of memorial natural resources which were only available from time to time in the surroundings. The close timing between changes in the use of the singular organo-mineral materials (preparation techniques, types of by-products) and cultural phases has enabled us to identify social discontinuities which correlate to distinctive geogenic events and search of the related exceptional resources. Based on the long-term record from Da’de, cosmic airbursts are suggested to be considered as a new class of dual-discontinuous signal of historical dimension, which have led to sudden (days to months) geogenic shifts in the availability of singular fuel resources and, simultaneously, to rapid cultural responses in their exploitation and use, depending on reactivity of local landscapes to the induced changes at short time scales (decades).  相似文献

This paper explores the issue of colonial borders through a case study of the intra-imperial boundary between Tunisia and Algeria, two territories under French rule between 1881 and the first decade of the twentieth century. The aim here is to understand what was at stake when it came to separating two territories holding different legal status but both administered by the French: Algeria which had officially become a French colony in 1830 and Tunisia which was given Protectorate status in 1880. The paper considers some of the many disputes over the border that took place both in the field and in colonial administrative offices. It also raises the question of the scope of colonial rule by exploring the way the border was never fully determined and was constantly redrawn by the inhabitants of the border regions themselves, who were presented first as tribes, and later, as either Algerian or Tunisian by the French civil and military administrations, and by the political authorities in Algiers, Tunis or Paris. As they all had their own interests in the matter, disputes were common but were also sometimes resolved in unexpected ways. Finally, the paper raises a further issue concerning the question of national identity in the context of the definition of national territories, which reveals the full ambiguity of the concept of identity in the colonial situation.  相似文献

Abstract

Recent decades have seen the rising of a vital, multifaceted politics in Canada, focused on the future relations between Aboriginal peoples and the Canadian state. While there are many debates about specific arrangements, there is consensus that the negotiated establishment of Aboriginal self-government constitutes a major piece of unfinished business for the Canadian federation. This essay seeks to contribute more structure and focus to contemporary debates by examining four different models of Aboriginal government: “mini-municipalities,” a third order of government institutions, the public government federal option, and nation-to-nation relations. Each form has different implications for the relationship between Aboriginal and Canadian political communities, and each has different implications for the institutions and practices of Canadian federalism. We argue that further concurrency of powers and greater asymmetries in intergovernmental relations are likely to be notable features of the Canadian federation, and that no single model or pathway is likely to emerge as the dominant one in the near and medium term.  相似文献

The majority of the neolithic pottery from Dhar Tichitt and Oualata bears abundant plant impressions on its surface. The present study involves direct examination of these impressions and comparsion with a control series in the laboratory. The criteria for differentiation between impressions made by wild and cultivatedPennisetum are clearly defined. In the pottery from Oued Chebbi (Dhar Oualata), the existence of many many impressions of pearl millet (Pennisetum), including both wild and cultivated strains, is confirmed. It is concluded that the area around Dhar Tichitt and Oualata belongs to a non-centre zone of origin (Harlan 1975) and that,ca 3000 bp, its inhabitants knew how to use cultivated strains in an area where wild strains were also found in some abundance.
Résumé La céramique néolithique des dhars Tichitt et Oualata présente une abondance d'empreintes végétales en surface. La présente étude—basée sur la lecture directe des empreintes sur la céramique—s'appuye sur une série de référence fabriquée en laboratoire. Les critères de différenciation, dans le genrePennisetum, des empreintes de formes sauvages et de formes cultivées sont clairement précisées. L'existence, dans les céramiques de Oued Chebbi, de nombreuses empreintes de mil du genrePennisetum et, parmi celles-ci, de formes cultivées, est affirmée. Les différentes analyses d'empreintes permettent de penser que le secteure des dhars Tichitt et Oualata appartient à la zone d'origine non-centre définie par J. Harlan (1975) et qu'aux alentours de 3000 ans bp, ses habitants savaient exploiter des formes cultivées dans un cadre où les populations de forme sauvage avaient une certaine abondance.
