Recent excavations in Ciemna Cave in the Pr?dnik valley near Ojców, southern Poland have brought to light new stratigraphic and techno-typological evidence concerning Late Middle Palaeolithic groups and their cultural affinities. In 2007, excavations began in the hitherto-unexplored main chamber of Ciemna Cave, with the goal of clarifying the results of previous work in other parts of the cave. During excavation the rocky floor of the cave was reached. About 1000 stone artifacts have been collected to date. Three cultural traditions have been documented: Mousterian, Taubachian, and Micoquian. Within the Micoquian tradition, three cultural levels were observed, which enriches the previous understanding of occupational phases at the site. These findings permit revision of the traditional terms “Pr?dnik industry” and “Pr?dnik technique.”  相似文献

Imperial charters issued to the cities of Italy in the eleventh and early twelfth century have been studied extensively for their presentation of social groups and the interaction of these groups with the imperial court. However, these studies have generally overlooked the role of these documents as political rhetoric. This paper argues that the terms and phrasing used to describe the people of Mantua in the imperial charters of the eleventh century were chosen for their political and ideological power, not for their ability to indicate a concrete social group.  相似文献

This article argues that the most severe crisis of masculinity among British and Dominion soldiers in the First World War did not take place on the Western Front. Instead, British and Dominion soldiers serving on the war's sideshows in Macedonia, Mesopotamia and Palestine believed most acutely that their manliness was in question. Unlike soldiers on the Western Front, they were not battling the main German Army, they were not fighting to liberate occupied France and Belgium, and their war was not to preserve the rights of small nations and the inviolability of international law. This article explores how military masculinity played out much differently on the war's peripheral fronts in two ways. First, it suggests that where a soldier fought mattered more to military masculinity than a soldier's method of enlistment or any other variable. British and Dominion soldiers were fully aware that the home front only considered France and Flanders as the real war, and they actively argued against this misconception to loved ones and in their memoirs. Second, this article demonstrates an additional crisis of masculinity on the war's peripheral fronts: the lack, or more often effacement, of non‐white colonial (Eastern Mediterranean and Arab) women. Not only was British and Dominion military masculinity under assault on the war's peripheral fronts, heteronormative sexual relations were also being transformed in a world where few, if any, racially acceptable women were available.  相似文献

This article draws on the perspectives of students and organizers involved in recent iterations of the Model Arctic Council (MAC), an experiential learning simulation designed to expand students’ knowledge and understanding of the Arctic and its governance. While much of the discourse related to simulations such as the MAC emphasizes its pedagogical and networking benefits, this article leverages participant-based ethnography to argue that the MAC also affects multi-track diplomatic outcomes in addition to serving as a site for diplomatic engagement. Applying an interpretive approach driven by the onset of practice-tracing in international relations, we demonstrate that the MAC both produces and constitutes diplomacy. Such a reimagination elevates the diplomacy of non-state actors and exposes false binaries between state diplomacy and non-state diplomacy.  相似文献

The spatial dimension is a key paradigm in price determination, as attested by recent studies in the literature that highlighted the differential in market behavior between spatial and non‐spatial pricing settings. In this paper, we develop a model of spatial pricing for multi‐market heterogeneously distributed resources, with an application to the Swedish forestry sector. The focus of the model is to estimate the impact of spatial interaction on the demand for resources in terms of resource allocation, competition, and pricing. In its core, the pricing mechanism relies on a supply–demand framework. Using disaggregated data at the gridcell level for forest feedstock supply and harvesting costs in Sweden, we construct regional supply curves for each gridcell assuming a maximum transportation distance to delimit the potential market. Demand nodes are exogenously determined and are adjusted using a distance‐decay model to assess demand pressure across locations. We apply the model empirically to assess the impact on forest feedstock prices of a 20 TWh increase in biofuel production.  相似文献
