A common criticism of the minerals resource rent tax (MRRT) was that it would ‘kill the goose that laid the golden egg’ for the Australian economy. Mining companies, their industry associations, and the Liberal–National Coalition all argued the MRRT would reduce Australia's attractiveness for mining investment, and lead to ‘capital flight’ as resource firms shifted towards lower-taxing competitors. To evaluate this claim, it is necessary to compare Australia's resource policy regime – including, but not limited to, its taxation elements – against those of its principal competitors. This article undertakes such an evaluation by comparing Australian resource policies with those of nine of its major mineral and energy competitor countries. This survey reveals that Australia's comparatively high mining tax rates are partially offset by its ‘non-interventionist’ approach to resource policy, and that it has retained good rankings on international political risk surveys. There is some evidence of short-term market response to the mining tax, but there is little evidence of sustained capital flight occurring due to the MRRT. These data collectively suggest that the MRRT did not significantly undermine Australia's attractiveness for international mining investment, despite widespread perceptions to the contrary.  相似文献

Recent archaeological investigation at the Coconut Walk site on the Caribbean island of Nevis revealed dense 40 cm deep midden deposits that accumulated between cal AD 890–1440. Analysis of invertebrate faunal remains reveals an assemblage dominated by nerite snails. We measured the length and width of more than 2700 tessellated nerite (Nerita tessellata) shells to investigate evidence for changing mean size that might be indicative of intensifying human predation pressure or other cultural and natural processes. Contrary to similar archaeomalacological studies in which size decline is detected, we observed a statistically significant size increase for N. tessellata over time. This size increase is coupled with increasing levels of tessellated nerite exploitation at the Coconut Walk site. Results suggest that tessellated nerite use was sustainable over several centuries of site occupation. Our findings have important implications for investigations of anthropogenic impacts on prehistoric mollusc populations. In addition, the findings reported here provide important insight into human subsistence patterns during the Late Ceramic Age in the Caribbean and a framework for comparison with observations from other Pre-Columbian sites in the Caribbean.  相似文献

The relationship between medicine and the arts, literature in particular, has many aspects. One of the most obvious relations is the use of literature as a source for historical studies. Jean-Martin Charcot and his school often appear in French literature at the end of the 19th century. Several aspects will be highlighted in this study, including (1) the ideas about degenerative diseases in the work of Emile Zola, the main author of the naturalistic movement; (2) decadence and spiritism in two transitional novels by Joris Karl Huysmans, who, once supporter of the naturalistic movement, changed his ideas following observations of disease and cure that could not be explained in a scientific way. Charcots work on hysteria and hypnosis, as well as Brown-Séquards rejuvenation experiments with testicular extracts played an important role with this respect; (3) Charcots relationship with the Daudets, in particular his treatment of Alphonses tabes dorsalis and the ambivalent attitude of his son Léon Daudet towards Charcot; (4) the influence of the lectures at the Salptrire on the work of Guy de Maupassant, who attended the lessons in the mid-1880s. The reading of novels and biographies of these authors provides a part of the social context and the cultural atmosphere in Paris at the “fin-de-siècle” when Charcot and his school played an important role in medicine. Moreover, it shows the influence of medicine and science on society as recorded by writers.  相似文献

Eight prehistoric wells dug to a depth of ∼2 m below the modern ground surface were found in the alluvial sediments of McClellan Wash on Gila River Indian Community in southern Arizona. Charcoal from the sediments filling the wells yielded radiocarbon ages of ∼1000 B.C. The time in which wells were dug coincides with a period of general regional aridity and high ENSO activity in the American Southwest. Digging to access water may have occurred in response to period(s) of resource uncertainty, or as a logistical activity that engaged increasingly resource-tethered Late Archaic/Early Agricultural populations. These activities laid the foundation for agricultural practices that eventually became the dominant mode of subsistence in the low-lying areas of the Sonoran Desert.  相似文献

In this paper, we share our experiences in designing, offering and evaluating undergraduate assignments that used information technologies to help undergraduate students from different universities collaborate on resource and environmental management problems in Canada. We focus on conditions of collaborative learning and peer review, especially how our uses of information technology reduced or increased the challenges of creating the conditions necessary for collaboration. In particular, we consider our successes and setbacks regarding five challenges: (1) composing effective groups, (2) providing sufficient time, (3) encouraging individual accountability, (4) enhancing regional perspectives, and (5) incorporating peer review and reducing competitiveness.  相似文献

A new sensitivity to the significance of historical experience has developed since the 2007 financial crisis. There are three possible ways of drawing on the past: as a source of advice on policies, of patterns of past evolution, of multiple possibilities. The best way of thinking about history is as a way of testing conventional hypotheses – particularly when those hypotheses are being used to create market opportunities (by making for false confidence; but also by engendering exaggerated despair).  相似文献

Examination of growth-stage profiles of shells from nine Northwest Coast shell midden sites shows a majority of senile-stage shells at longer-term residential sites and a majority of mature-stage shells at shorter-term encampments. This pattern indicates less intensive harvest in the vicinity of residential sites, which is consistent with management and conservation of resources for anticipated future needs. Consideration of environmental and taphonomic factors does not account for the observed inter-site variability. Shellfish conservation in the vicinity of residential sites is evident for the period of the past 7000 years.  相似文献

In the Pacific region, the onset of modern El Niño/Southern Oscillation (ENSO) activity at approximately 5000 years ago may have played a significant role in the development of cultures in the Pacific basin. Within Australia, similar trends in population and resource use have been identified but largely ascribed to cultural changes. To test human responses to changing ENSO activity through the Holocene we analysed a comprehensive suite of 710 radiocarbon ages from archaeological sites in ENSO-sensitive Queensland. We observe a dramatic and sustained increase in landscape activity at inland sites from 4860 ± 15 years ago, statistically indistinguishable from the timing of the onset of modern ENSO activity. Subsequent changes in long-term activity directly impacted on human populations indicating that once established, ENSO maintained a continuous influence on disparate cultures throughout the Pacific basin.  相似文献

In the Pacific Northwest of North America, researchers routinely suggest changes in human use of animals explain hunter-gatherer organizational changes and development of cultural complexity. For example, most models developed to explain developing cultural complexity invoke salmon in some fashion. Yet until recently, fish remains were not carefully studied and more generally, zooarchaeological evidence has not been systematically used to test models of culture change. This study reviews the 10,000-year-old faunal record in the Pacific Northwest to test predictions drawn from models of resource intensification, resource depression and hunter-gatherer organizational strategies. The records from two subareas, the South-Central Northwest Coast (Puget Sound/Gulf of Georgia) and the Northern Columbia Plateau, are examined in detail, representing 63 archaeological sites. While minor changes in animal use are evident, the overall record is characterized by stability rather than change.  相似文献
