ABSTRACT. The problem of locating a point that is as far as possible from arcs and nodes of a network is investigated. Each arc or node may have a different multiplicative factor (weight) for its distance. A graphical solution approach, as well as a computational algorithm, is presented.  相似文献

Abstract. Four states have disappeared as a result of the collapse of communism and many others have come into being. I want to look at the reason why these states have disappeared, what this says about the nature of state-sustaining ideologies and what the disappearance tells us about the relationship between statehood and nationhood. I will also look at the effectiveness of communism as a state-sustaining ideology. The four are, obviously, the Soviet Union, Yugoslavia, Czechoslovakia and East Germany. In each case, the survival of the state was linked to communism and the end of communism brought their continued existence into jeopardy. I shall not be looking at the Soviet Union in detail. Broadly, the construction of political identities can come about in two ways – by ethnicity or by the state. Each gives rise to a different set of loyalties, creates its own panoply of rituals etc. When the two coincide, the mythical nation-state can be said to be in being, but this hardly exists in reality (Iceland may be the sole exception in Europe).  相似文献

There is no doubt that medical semiotics are having a revival at the moment. Different aspects of yesterday's and today's interest in semiotics and in the historical interpretation of signs of disease in the context of theory and history of medicine can be illuminated: their deciphering as the history of the sign in medicine by historic science, their overestimation by philosophy during the Age of Enlightenment, their reduction to a phenomenology of medicine and natural science during the first half of the 19th century and their transformation to medical diagnostics since the middle of the 19th century and recently even their functionalization as methodical instrument within the history of science. The following will show the change in meaning of medical semiotics. Modern development and especially the transition to medicine, based on natural science, will be emphasized.  相似文献

Land has become the source of new end more complex disputes in Papua New Guinea in recent years. Economic opportunities associated with government programs and multinational corporations have altered land values in rural districts. This paper examines how in the context of such shifting attitudes toward land, competing groups in an Eastern Highlands district use both law and violence in their confrontations. One component of the legal strategies pursued includes the elaboration of clan stories to legitimize claims before the courts. Yet, while rural elites and their families may desire the support of the law in their economic pursuits, the realities of intergroup violence set limits on the likely success of this approach.  相似文献
