Organic fertilizers have the capacity to alter the nitrogen isotopic composition of plants. Camelid dung and seabird guano are two potentially important fertilizers in the agricultural systems of western South America, particularly Peru and Chile. This paper presents isotopic data (δ13C and δ15N) from field grown plants (maize, Zea mays) fertilized with the following four treatments: CO (control, no fertilizer applied), AS (ammonium sulfate, a chemical fertilizer), DU (camelid dung), and SG (seabird guano). Plants were grown in experimental plots in the Virú Valley, northern Peru. Plants fertilized with the chemical fertilizer presented very similar isotopic compositions compared to the control. Conversely, the camelid dung fertilized plants were characterized by higher δ15N values compared to the control plants (by 1.8 to 4.2‰ depending on the plant part). The seabird guano fertilized plants were greatly enriched in 15N in comparison to the control plants (by 11.3 to 20.0‰). The results of this study have important implications for the reconstruction of human diet using isotopic data derived from bone collagen and related tissues, particularly in the prehispanic Andes, but also in Europe and North America during the 19th century, when Peruvian seabird guano was used extensively. Specifically, the interpretation of the relative contributions of plant and animal protein to the diet on the basis of bulk isotopic compositions of bone collagen (or similar tissues) may be confounded by camelid dung fertilization if the carbon isotopic compositions of the two sources are similar. Likewise, the interpretation of the relative contributions of maize and marine protein may be confounded by seabird guano fertilization. 相似文献

White socio-spatial epistemology 总被引:1,自引:0,他引:1
Recent work by geographers concerned with the enduring presence of racism has called for an interrogation of the privileges and contingencies of whiteness. Central to this project of denaturalizing White Identity has been the disclosure of its co-constitution with a host of social practices. Building on the work of critical theorists in the humanities and social sciences concerned with masculinist and post-colonial epistemologies, this paper outlines a socio-spatial epistemology of whiteness. Whiteness's central tenets are an essentialist and non-relational construction of space and identity that underwrite its claims to be realized independent of an Other. Spatially, this refusal manifests itself in the deployment of discursive categories associated with scales, boundaries and extensivity in ways that reify space into discrete, unrelated parcels. We discuss some of the implications of this non-relational construction of space and identity in the context of residential segregation and spatial mobility. The paper concludes by noting that historically and geographically specific forms of whiteness have drawn upon a common socio-spatial framing and that further study in this field will benefit anti-racist activism by disclosing the workings of racialization in numerous human geographic contexts. 相似文献

Although artists must usually be self‐reliant when managing their business, an artist’s education typically concentrates on artistic skills rather than managerial knowledge. This paper analyses the current curricula of 154 art institutions (public and private), focussing on the so‐called DACH countries (Austria, Germany and Switzerland). The results show a deficit in the implementation of economic and, especially, business‐related topics in the education of artists at art universities and institutions. A glimpse at Anglo‐American countries shows that, unlike in Europe, art schools are more open‐minded about implementing economic content into their curricula. 相似文献

The twelfth-century poet Nizāmī Ganjavī has produced his version of the adventures of Alexander as a unique composition mingling known Persian historiography and Qur'anic legends with unusual non-Islamic, especially Greek, elements in order to create his Iskandar-nāma (containing two parts, the Sharaf-nāma and the Iqbāl-nāma) as a synthesis of eastern and western cultures. A first point is the examination of the reasons behind the importance given to wine and drunkenness within the narrative. The poet has stressed this further by heading each chapter with a call to the sāqī. The essay examines the appositeness of the invocations with the episodes in the narrative, it analyses examples of wine imagery (containing references to medicine, to the mirror and to religion) and questions the relation between authorial persona, narrator and characters, examining in particular the famous teetotaler claim in one of the introductory chapters of the first part of the Iskandar-nāma. 相似文献
