Prolonged stability of the southern tableland of NSW, developed on early Tertiary Monaro basalt, is evident from weak landscape dissection and numerous small lakes. However, poorly developed soils and weathered zones are inconsistent with prolonged Cainozoic weathering or formation under climates substantially different to the present. Thin Holocene sediments are also at variance with the sizes of the lake basins. Low depositional landforms, termed ‘lake shadows’, occur on the eastern perimeters of most lakes, and comprise clay pellets blown from basin floors during dry phases. Deflation, dominantly during Quaternary glacial periods, and reactivated today, is responsible for the thin soils and sediment cover. The lake basins are partly solutional and partly deflational features. The modern soil cover reflects the modern climate.  相似文献

Colonial societies revolved around nuclear families. Though they often seemed natural, universal and inevitable, colonial nuclear families were in fact produced through a series of laws and customs that regulated sex and marriage. These legal, social and cultural practices conspired to make the family an adaptable and formidable social institution, both a pillar and a beneficiary of colonization. Hegemonic but not universal, family members were privileged over other members of colonial societies, who not only survived on the margins and in the shadows of colonialism, but also played crucial roles in resettlement societies.  相似文献

Starting from an econometric model of local employment growth, applied to Canada (1971–2001), residuals—relative to model predictions—are analyzed over time and over space, in turn allowing us to draw a distinction between general explanatory variables and factors of a more local, cyclical or accidental nature. The model's explanatory power grows over time, founded on variables such as urban size, market access and industrial structure, allowing us to conclude that local employment growth in Canada follows an increasingly geographically predictable pattern. However, an examination of the residuals reveals more localized processes. Growth volatility is most manifest in Alberta and British Columbia, home to the most erratic local economies. Emerging patterns are visible in the last period, most notably the underperformance of Northern Ontario and of non‐metropolitan communities between Windsor and Québec City, lying along the Great Lakes and the Saint Lawrence. The over‐performance—compared to model predictions — of small and mid‐sized towns in south‐eastern Québec can, on the other hand, be interpreted as a sign of truly local social processes, generally associated with a particularly dynamic local entrepreneurial class.  相似文献

Terrorist attacks on the United States, Spain and the United Kingdom have underlined the differing responses of Europe and the United States to the 'new terrorism'. This article analyses these responses through the prism of historically determined strategic cultures. For the last four years the United States has directed the full resources of a 'national security' approach towards this threat and has emphasized unilateralism. Europe, based on its own past experience of terrorism, has adopted a regulatory approach pursued through multilateralism. These divergences in transatlantic approaches, with potentially major implications for the future of the relationship, have appeared to be mitigated by a revised American strategy of counterterrorism that has emerged during 2005. However, this article contends that while strategic doctrines may change, the more immutable nature of strategic culture will make convergence difficult. This problem will be compounded by the fact that neither Europe nor America have yet addressed the deeper connections between terrorism and the process of globalization.  相似文献

In my replies to the perceptive and cogent observations and questions about my book offered by Warren Breckman, Robert Clewis, and Espen Hammer, I emphasize the thought that we must learn to live with standing tensions between settled institutions and improvisatory courses of action. In reply to Breckman, I suggest that Münchhausen's Trilemma is best regarded as a practical problem that should be addressed in different ways in different contexts rather than as an epistemological puzzle to be solved, and I embrace his rejection of methodological individualism. Although our evolved biology sets some limits and some possibilities, our practical lives are also relatively autonomous from biological determination. In reply to Robert Clewis, I emphasize that Kant has a picture of divine noumenal causation, dimly discernible in history and operating principally through human beings as agents, and I suggest, with Kant, that we may well be unable to explain in any satisfactory way the nature of this noumenal causation. In reply to Espen Hammer's worries about whether a dialogue between Kant and Benjamin is really possible without doing violence to one side or the other, I stress that I am not myself trying to develop a single consistent theory of the meaning of history. Instead, I am “working through” my own perplexity at the constitutive tensions that shape human life, including my own, and trying to see those tensions more clearly.  相似文献
