Australia has had a long connection with, and significant national interests in, the Southern Ocean and Antarctica. The Australian Antarctic Territory comprises 42 per cent of Antarctica's landmass. Australia is not only a claimant state and original signatory to the Antarctic Treaty but has played a significant role in the development of what is termed the Antarctic Treaty System (ATS). This article aims to provide an overview of Australia's key policy interests and government policy goals towards Antarctica, including its commitment to the ATS. In examining key policy objectives we note that despite continuity and development of these objectives, significant changes and challenges have arisen in the period 1984–2006. It is these challenges that will help frame Australia's Antarctic agenda over the next 20 years and beyond.  相似文献

Art History?     
This article is presented in two parts. In part I, I call into question the viability of a currently received opinion about the foundations of the subject called “Art History,” primarily by challenging assumptions that are implicit in conventional uses of the terms “art” and “work of art.” It is widely supposed that works of art are items of a kind, that this kind is the bearer of the name “art,” and that it has a history. In part II, I propose to correct this error by using the word “art” in a presently unconventional—although not unprecedented—way. The proposal relies upon a concept of cultural evolution running intellectually parallel to a Darwinian account of genetic evolution. The thesis has strong metaphysically realist implications, relating cultural evolution to what can be said and done and can properly be seen to have a history only in a universe to which real regularities are attributed. The recommended use of the term “art” is secured upon an estimate of the role of memetic innovation as radically pervasive, embracing all thought and action. “Art,” understood in the suggested way, becomes the name of a category, which has no history as kinds have histories.  相似文献

A popular approach to examining the effects of public policy has been to rely on a spatial data sample of border counties as in Holmes (1998)—border counties from a sample of states that are used in conjunction with least‐squares estimation techniques in an attempt to isolate the policy impact while controlling for spatial dependence that often arises from latent or unobserved variables. This technique is in the spirit of control‐group methodologies from the laboratory sciences. This paper contrasts border‐county estimation results from Holmes' (1998) approach and those from a related methodology set forth in Holcombe and Lacombe (2003), with estimates from a spatial autoregressive model explicitly accounting for within‐state and between‐state public policy effects. As an illustration, the paper examines the effects of Aid to Families with Dependent Children (AFDC) and Food Stamp payments on female‐headed households and female labor force participation using the three different methods.  相似文献

The rational system of medicine distinct from magical or religious practices originated with Hippocrates. This revolutionary change established diseases with natural causes and treatments. Epilepsy with its prominent physical and psychic features was regarded in ancient times with superstitious awe and given the name "Sacred Disease." Hippocratic authors distanced themselves from the prevailing supernatural views but were careful not to oppose the traditional medicine especially the cults of Asklepios. This analysis of the practices of Hippocratic and Temple medicine in relation to epilepsy reveals some clear differences and also some overlapping features.  相似文献
