During the first half of the twentieth century, despatches about the coldest corner of the British Empire were circulated to three, sometimes four, of its southern neighbours under the British crown: Australia, New Zealand, South Africa and the Falklands. Of these four, South Africa seemed the least interested in Antarctica, despite the keen interest of some influential individuals and a strategy of bringing Antarctica into the imperial fold through British dominions that were proximate to Antarctica. In this context, we ask how South Africa viewed itself in relation to the Antarctic to the south and the British metropole to the north. We discuss the key activities that connected South Africa to Antarctica—whaling and weather forecasting. Moreover, we consider some of the enterprising plans for a South African National Antarctic expedition, and what these plans reveal of South Africa's perception of itself as a southern country. This article interlinks with a growing scholarship that is critical of treating Antarctic history as politically and culturally isolated, including showing how the relatively simple natural and political ecology of the Antarctic can throw into relief multiple national and international concerns. 相似文献

Gordillo, S., 2013. Muricid boreholes in Pleistocene acorn barnacles from the Beagle Channel: trophic interactions during the Last Interglacial in southern South America. Alcheringa 37, 1–8. ISSN 0311-5518.Acorn barnacles with boreholes were recovered from a Pleistocene marine deposit on Navarino Island, on the southern coast of the Beagle Channel. Balanomorph shells were identified as Balanus laevis (Bruguière, 1789), and a few bear small round holes located generally on the middle or apical part of the parietal plates, thus suggesting that they represent the work of small muricid predators. If so, this study is the first record of drilling predation on fossil barnacles reported in southern South America.[Sandra Gordillo [sgordillo@cicterra-conicet.gov.ar], Centro de Investigaciones en Ciencias de la Tierra, Consejo Nacional de Investigaciones Científicas y Técnicas (CICTERRA, CONICET-UNC); Centro de Investigaciones Paleobiológicas (CIPAL), Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba.

The Viking Age was an important watershed in European history, characterized by the centralization of authority, the adoption of Christian ideology, the growth of market trade, the intensification of production and the development of urbanism. Together, these phenomena mark the beginning of Scandinavian state formation. However, the dates at which each occurred - and the unequal rates at which different state attributes were adopted in 'cores' and 'peripheries' - remain to be fully explored and explained. These issues can be illuminated by world-systems theory and brought into focus by studying the date at which key aspects of the Viking Age were adopted in a Scandinavian periphery - the Norse Earldom of Orkney and Caithness, northern Scotland. The present study questions not only why peripheries change, but why they do not change, or change more slowly than neighbouring cores. 相似文献

Rescue excavations in Prohear, southeast Cambodia, recently saved the last untouched graves of one of the richest prehistoric sites in Southeast Asia. Many Iron Age burials dating from the 2nd century BC to the 1st century AD contained gold and silver ornaments so far unknown from archaeological contexts together with indications for the presence of an immigrated elite. A first selection of 59 objects were analysed by LA-ICP-MS to obtain detailed information about the composition, as well as minor and trace elements. The majority of the ornaments consist of electrum and auriferous silver with low copper concentrations, and two main groups indicating different alluvial gold sources can be distinguished by different concentrations of Pt, Ir, Bi and different Pd/Pt ratios, one group being related to rich burials with non-local features. The SEM and EDX analyses of four objects revealed two different gilding techniques observed for the first time in Southeast Asian artefacts: foil-fusion gilding, related to special Ag–Au–(Cu)–Sn alloys containing up to 4% tin, and depletion gilding. 相似文献

Hiram Bingham Jr, Protestant missionary, landed at Abaiang in the Gilbert Islands in November 1857. He came not only with a distinct missionary policy but also with an inner vision based on his ideals and his own personal interpretation of the Protestant Christian message. Bingham envisaged a loving community which was made up of both ruler and the ruled, including men and women, young and old. For their part, Gilbertese on Abaiang did not share Bingham's view of God or the cosmos. They had their own spirits (Anti) and lived in a world punctuated by wars. Given their limited contact with Europeans, most Islanders on Abaiang and Tarawa saw little relevance in the particular type of Christianity that Bingham espoused and attempted to convey to them. Yet despite this dissonance, two war chiefs (uea) began a communication. This communication was meaningful to their side but was not shared by the other. Bingham was perceived in a way he would not have wanted and he, in turn, misinterpreted the entire situation in Abaiang and nearby Tarawa. The result was that the missionaries became embroiled in the wars and failed to usher in a reign of peace and benevolence. 相似文献

We develop material to determine whether or not an arbitrary number is Löschian; the procedure embodied in the theorems achieves the desired result more swiftly than do previous solutions to this problem. The correspondence between a partition of the central place lattice and a quadratic form permits the rapid determination of the lattice coordinates of an arbitrary Löschian number and of the exact shape of a single fractal generator used to form an entire central place hierarchy associated with an arbitrary Löschian number. Central place hierarchies may be generated geometrically using a single shape applied initially to a hexagon and subsequently, scaled appropriately, to resultant polygons. Fractional dimensions of arbitrary central place hierarchies, measuring their “space-filling” characteristics, follow naturally from this general procedure. 相似文献

The literature contains many definitions of the rural-urban fringe, but it is difficult to find consensus on how many zones it contains, or how they can be mapped. It is argued in this paper that transitions within the fringe and at its borders are continuous rather than abrupt. In a study area adjoining London, Ontario, cluster analysis is used, and it leads to the identification of three norms. Membership probabilities are then mapped on the basis of each areal unit's resemblance to these norms through discriminant analysis.
Dans la litterature, il y a beaucoup de definitions de la fringe péri-urbaine, mais on discute le numéro de zones dans la fringe et la méthode de sa cartographie. On raisonne ici que les transitions dans la fringe et sur ses bords sont continues plutôt qu'abruptes. Dans cette étude des environs de London, Ontario, on emploie de 'cluster analysis' qui donne l'identification de trois groupes normatifs. On en fait une carte des probabilités d'adhésion sur la base du correspondance de chaque unité aréale à ces groupes normatifs par l'analyse discriminatoire. 相似文献
