Interactions between saints and animals have been the focus of modern scholarship, yet an important aspect has been neglected, namely that of the saint as healer of animals, when a third party has requested help on behalf of the animal. This article therefore examines, through examples drawn from saints' Vitae and other sources, the types of animals for which saintly intervention was sought, the ailments from which they suffered, and the form which their cure took, in order to understand why medieval people turned to the saints when their animals were ill. An examination of this relationship between saint and animal will not only elucidate the role of saint as thaumaturge, but will also shed light on the veterinary aspect of animal welfare. 相似文献

Hydrothermal water–(pyroclastic) rock interactions were examined using flow-through experiments to deduce the effect of mass transport phenomena on the reaction process. A series of experiments were conducted over the temperature range 75–250°C, with a constant temperature for each experiment, and at saturated vapour pressure, to estimate the apparent rate constants as a function of temperature.
Based on the chemistry of analysed solutions, the water–rock interaction in the experiments was controlled by diffusion from the reaction surface and by the existence of a surface layer at the rock–fluid interface, which regulated the chemical reaction rate. The reaction progress depended to a high degree on flow velocity and temperature conditions, with element abundances in the fluid significantly affected by these factors. Mass transport coefficients for diffusion from the rock surface to the bulk solution have been estimated. Ca is selectively depleted under lower temperature conditions ( T < 150°C), whereas Na is greatly depleted under higher temperature conditions ( T > 150°C), and K reaction rates are increased when flow velocity increases. Using these conditions, specific alkali and alkali earth cations were selectively leached from mineral surfaces. The 'surface layer' comprised a 0.5–1.8 mm boundary film on the solution side (the thickness of this layer has no dependence on chemical character) and a reaction layer. The reaction layer was composed of a Si, Al-rich cation-leached layer, whose thickness was dependent on temperature, flow velocity and reaction length. The reaction layer varied in thickness from about 10−4 to 10−7 mm under high temperature/low fluid velocity and low temperature/high fluid velocity conditions, respectively. 相似文献

Abstract: While the critical literature has focused on the geography of oil production, the politics of "outrageous" gasoline prices in the United States provide a fertile path toward understanding the wider geography of petro-capitalism. Despite the deepening contradictions of US oil consumption, "pain at the pump" discourse projects a political sense of entitlement to low priced gasoline. I use a value-theoretical perspective to examine this politics as not only about the quantitative spectrum of price, but also the historical sedimentation of qualitative use-values inscribed in the commodity gasoline. Gasoline is analyzed both as a use-value among many within the postwar value of labor power and as a singular use-value fueling broader imaginaries of a national "American way of life." While use-value still represents an open site of cultural and political struggle infused within value itself, the case of gasoline illustrates how use-values are not automatically mobilized toward politically savory ends. 相似文献

Despite the existence of research conducted by geographers eschewing or professing religious faith, the influence of researchers and their methods have yet to receive critical attention within the study of religion. The experience of three geographers working on a three-year research project suggests that it is vital to reflect upon the inter-subjective relationships and methodologies used to reconstruct the religious past. How do different subject positions influence our selections from historical records? We also consider whether the spatialities of putatively 'religious' archives, whether formally or informally constituted, make a difference to the construction of historiographical knowledge. In attempting to answer these questions, the paper argues that developing an awareness of different types of positionality, vis-à-vis religious faith and practice, combined with reflexivity, vis-à-vis methodology, can enrich the interpretative reconstruction of the religious past. 相似文献

Of scales, networks and assemblages: the League of Nations apparatus and the scalar sovereignty of the Government of India 总被引:1,自引:0,他引:1

Whilst greatly valuing recent critiques of the vertical imaginary and reified ontology of scale theory, and of the unfettered flows of network theory, this paper argues against a human geography without scale. Rather, four propositions from the theoretical literature are used to provide a tool-kit to analyse the practical negotiation of scalar politics, namely that: scales should be considered as effects, not frames or structures, of practice; networks must be considered in all their complexity and heterogeneity; networks can be interpreted as assemblages, the more re-territorialising and re-scaling of which can be analysed as apparatuses; and that state apparatuses work to create the impression that scales are ahistorical, hierarchical and possess exclusive relationships. These propositions are used to explore a period of history when the scalar constitution of the world was under intense debate. The interwar era saw the imperial scale clash with that of the international, both as ideological worldviews, and as a series of interacting institutions. The assemblages of internationalism and imperialism were embodied by apparatuses such as the League of Nations and the colonial Government of India respectively. Attempts by the League to encourage the abolition of tolerated brothels in an attempt to reduce the trafficking of women and children led to intense debates between the 1920s and 1930s over what constituted the legitimate domains of the international and the 'domestic'. These explicitly scalar debates were the product of League networks that threatened the scalar sovereignty of the Raj, most directly through the travelling Commission of Enquiry into Traffic in Women and Children in the East in 1931. 相似文献

Archaeological surface finds are difficult to date. There are several useful methods, but each requires special circumstances and has one drawback or another. On the west coast of South Africa marine shell are abundant on surface sites but they are rarely dated because they are perceived to be in disturbed context and in questionable association with artefacts. This paper attempts to rectify this misconception and shows that, although far from perfect, a large suite of surface dates can shed as much light as excavated data. On the Vredenburg Peninsula they help refute the hypothesis that two economically and culturally distinct populations shared this pre-colonial landscape since 2000 BP. 相似文献

The reconstruction of Palaeolithic subsistence and settlement systems at the Middle Palaeolithic site of Payre (France) is undertaken through the application of dental wear analyses combined to zooarchaeological, technological, and ecological indicators. Three archaeological levels were investigated. Level D, dated to MIS 5, could correspond to an occupation during the cold season. In levels G and F, dated to MIS 8-7, animals were probably hunted during a warmer season. According to dental wear analyses, it is likely that level F has actually recorded a succession of short occupations, contrary to what is observed in the levels G and D. Those differences in the duration of site occupation are discussed in the light of previous sedimentological, zooarchaeological, and technological studies. 相似文献

The representation of history continues to evolve in the domain of museum exhibitions. This evolution is informed in part by the creation of new display methods—many of which depart from the traditional conventions used to achieve the "museum effect"—in part by an increased attention to the museum-visitor relationship. In this context the ethical force of bearing witness, at times a crucial aspect of the museum experience, has emerged as a particularly compelling issue. In seeking to represent and address atrocity, injustice, and the abrogation of human rights, museums have the potential to become "sites of conscience" and to encourage "historical consciousness." Through a series of three exhibitions devoted to slavery, the New-York Historical Society demonstrated how such sites can be constructed and how objects can be deployed to represent extreme or "limit cases." In this review/essay I investigate and interrogate these exhibitions, looking closely at the use of objects as a source of "indirect testimony" (Marc Bloch) and at the "dialogical situation" (Paul Ricoeur) that might arise in an encounter among objects, exhibit narratives, and visitors. Thinking in terms of point of view, I look at the variety of rhetorical platforms from which objects speak in these exhibitions; thinking in terms of syntax, I look at the effects of ordering and of the radical juxtaposition of objects; thinking in terms of irony, I look at the provocations of double-voiced narratives and at how objects are used to support those historical sentences. 相似文献
