The rapid expansion of non‐ferrous metallurgy in the late Middle Ages (14th–15th centuries) enhanced ore demand, which was supported by mining intensification. Metallurgical workshops developed various supply strategies based on geological, political and economic constraints. This is particularly true for the Pyrenean multi‐metals workshop of Castel‐Minier (Ariège, France), where recent excavations unearthed an exceptional corpus of non‐ferrous ores. A specific analytical methodology combining micro‐Raman spectroscopy and environmental scanning electron microscopy with energy dispersive X‐ray (ESEM‐EDX) was set up to study these artefacts. This composite methodology permitted the fast characterization of both mineral and gangue as well as a discussion of their economic potential. Ores identified were compared with ancient mines in neighbouring mining districts in order to sketch a geography of the mineral resources available to medieval metallurgists. Moreover, a chrono‐stratigraphic study of ore distribution in Castel‐Minier revealed the supply strategies, technological choices as well as spatializing of copper and lead metallurgies. 相似文献

Fractals, as a mathematical concept, made their way into many scientific fields, but have also inspired artistic creations, in particular the plastic arts. The art exhibition «Fractal Time» gives us the opportunity to analyze the link between «art under fractalism» and mathematics. Metamorphoses of the concept, as it goes further its original field, provide us information on the relation between its initial theoretical ground and its additional esthetical meaning. We propose to distinguish, according to a criterion of theorical but non esthetical distance, three ways of derivation for «fractalism»: technical derivation, esthetical actualization and ideological actualization. *** DIRECT SUPPORT *** A01KB003 00010 相似文献

Can age, period and cohort effects help explain support for Quebec sovereignty? Previous work on this question has focused mostly on the effects of age and cohort. We contribute to this debate by adding a period perspective. As such, our study is the first to investigate the impact of age, cohort and period effects in a single study of opinion towards sovereignty in Quebec. We take advantage of an original dataset that includes survey data collected between 1985 and 2012. We use these data to examine the impact of age, birth year and survey year on support for this constitutional option among francophone Quebeckers. Our results are in line with previous work: we show that younger Quebeckers are more likely to support sovereignty, and that some cohorts – namely, respondents born between 1945 and 1959 – are also more likely to favour this option. Perhaps more surprisingly, we find that specific events are comparatively the most important factor to explain fluctuations in Quebeckers' attitudes towards sovereignty. 相似文献

New TFP estimates drawn from the neglected census of 1831 for Lower Canada are used to test the controversial (but still dominant) traditional “poor French farmers” explanation for a prolonged economic crisis. The new evidence shows that French-speaking areas were equally as productive as English-speaking areas, something that upturns the established consensus and reinforces the minority viewpoint that culture had little to do with the crisis. Using a broad range of controls, the researchers find that this conclusion is robust and that other variables such as settlement recency, environment, and economic structure were much more significant determinants of TFP. These results warrant the abandonment of the cultural explanation and a shift toward other explanatory channels. 相似文献

The construction of historical frame of reference based on the distinction between and articulation of phenomenological and chronological times. As it relativises the notion of simultaneity and inverts its relation to causality, the special theory of relativity can induce analogous modes of reflection on the themes of “contemporaneity” in the history of art (Panofsky) and in epistemology (Bachelard). This “relativist” method, often misunderstood, sheds light on both historical and presentist methods. 相似文献

Eruvim: Talmudic places in a postmodern world 总被引:1,自引:0,他引:1
Peter Vincent & Barney Warf 《Transactions (Institute of British Geographers : 1965)》2002,27(1):30-51
Lodged in the heart of Western urban space, eruvim are religious enclaves important to Orthodox Jewish culture. Eruvim enable acceptable behaviours on the Sabbath as defined by Talmudic theological dogma. Work, and the carrying of all objects associated with work, is prohibited in public spaces on the Sabbath by the Talmud, yet within the boundaries of the eruv, many such restrictions are relaxed, facilitating social interaction and community cohesion. This paper examines the religious and spatial dimensions of eruvim, including the obsessive detail paid to the demarcation of their boundaries, which serve as metaphorical walls and doorways. It also explicates the local politics through which private space is effectively extended into public space. Conceptually, the paper situates the topic within broader concerns about diasporic Jewish identity, which is threatened by assimilationism, slow demographic growth and secularization. It invokes recent theories concerning the spatialization of consciousness and subjectivity, noting the recent growth of eruvim as part of the global surge in ethnic identity that has emerged as a backlash to postmodern capitalism. 相似文献
