We conducted experiments to compare the micromorphological signatures of modern burnt sedge and grass bedding to laminated layers of carbonized material and phytoliths in Middle Stone Age deposits at the shelter, Sibudu. The experiments were designed to clarify the formation processes associated with the laminated layers and to investigate whether these previously identified layers of bedding were deliberately burned or not. The results indicate that the laminated layers were most likely produced by human activity related to the construction, maintenance and burning of bedding. Furthermore, our experiments demonstrate that large volumes of vegetal material could have produced the relatively thin, archaeological deposits of burnt bedding. 相似文献

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

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

The Swiss Cantons had no greater admirer in the eighteenth-century than the French political thinker Gabriel Bonnot de Mably. The feeling was mutual, at least to some extent, since the Bernese Patriotic Society awarded its first prize in 1763 to Mably, for his dialogue Entretiens de Phocion. The prize then led to an exchange of letters, stretching across some two decades, with Daniel Fellenberg, founder of the Patriotic society—the most important block of Mably's correspondence to have survived. This essay considers the 1763 prize and the correspondence with Fellenberg for the light they cast both on Mably and on Bernese participation in the wider currents of eighteenth-century thought. 相似文献
