This paper investigates a conjecture of Lowell regarding the number of neighbors on maps divided into regions. Lowell speculated that border regions have on average three neighbors and that nonborder regions have on average six neighbors. This paper investigates the conjecture and, for a large category of maps, an exact relationship is obtained. Exceptions to this large category are considered, and a further exact relationship is obtained. The results of this paper may find applications not only for geographic maps, but also for models involving planar networks. 相似文献

The great Swedish warship Vasa capsized and sank in Stockholm harbour on her maiden voyage in 1628. The ship was raised from the seabed in 1961 and skeletal remains were recovered from at least 25 individuals, with teeth and jaws from 17 of them. The skeletal material was odontologically examined, including dental radiographs. Teeth lost both ante‐mortem and post‐mortem were recorded and variations in tooth anatomy noted. Acquired changes were recorded including enamel hypoplasia, attrition, dental caries and periodontal recession. Age estimations based on a separate odontological study, osteological changes and tooth attrition had been made in 1989. Ages were estimated additionally by three non‐destructive dental methods based on (a) the length of the apical translucent zone, (b) selected measurements both on intact teeth and from ratios on dental radiographs and (c) ratios of the length and width measurements on dental radiographs from selected teeth. Several sources of post‐mortem changes had been observed, among them vivianite in 33 teeth from four individuals. The results of the dental examination showed that few teeth had been lost ante‐mortem, there was a low caries rate and little loss of periodontal attachments. With few exceptions, there is fairly good agreement between the different methods of estimating age. Age estimates based on dental attrition were, however, significantly different from the other dental methods and age estimates calculated from apical translucency ought to be regarded with scepticism due to post‐mortem changes. The chronological ages of the victims will never be known, but age estimates based on all the age‐markers available will probably reach a fairly close approximation.

ABSTRACTChina’s engagement within the South Pacific has increased dramatically in recent years mainly through significant increases in development assistance. Development assistance is provided to address humanitarian needs but to also secure national interests of the donor. This paper examines the extent and nature of Australia’s and China’s influence in Vanuatu from the perspectives of the Ni-Vanuatu people using new data. China is perceived as having the most influence in the country despite Australia’s development assistance being viewed far more positively. Support for infrastructure is the most important factor contributing to a positive image for both countries. Perceptions of land grabbing are the main factor contributing to negative images. Regional differences in perceptions of Australia and China across Vanuatu also exist. 相似文献

The idea of forging a linkage between global trade and labour standards has a long history and has been the subject of fierce debate. In a global political economy that incites ‘competition for jobs’, the idea cannot escape controversy. Crucially, it has failed to win significant support from trade unionists in the global South. Drawing on viewpoints voiced by workers’ rights activists in South Africa and Brazil, this article presents four propositions on the features and functions that a labour–trade linkage would have to possess if it is to serve workers’ interests, and explores whether and how these may be accommodated by the ILO and WTO regimes. It is argued that a linkage requiring a new single WTO undertaking is out of the question; a linkage would only make sense if it superimposes ILO rule onto the WTO, not the opposite; a linkage should be premised on positive trade measures; and, finally, it should serve the interests of presently unprotected and unorganized workers. Overall, the main challenge of such a linkage would be to achieve the necessary reform within the ILO. 相似文献
