This paper analyses two critiques of the jurisprudential basis of settler colonialism in Australia published in the early Victorian periodical press. Review articles in the North British Review and Fraser's Magazine in the 1840s deployed claims of legal sophistry to dispute the fiction that Australian colonies were settled, rather than conquered, and that the country was a terra nullius. By examining the politics and rhetoric of each article, the significance of legal ideology for both literature promoting colonization and humanitarian critiques of colonial policy is assessed. Through a combination of discourse analysis and intellectual history, the North British Review article is read as fusing Scottish Enlightenment concepts of social evolution with the rhetoric of sensibility to defend the existence of Indigenous rights to land and to argue for the degenerative implications of colonial social practices. Similarly, the Fraser's Magazine article offers an epitome of the place of law in colonial policy-making by invoking utilitarian and pragmatic approaches to law to rationalize doctrines of sovereignty and jurisdiction, minimizing legal protections for Aborigines while maximizing the legal powers of colonists. By tracing the use of jurisprudential rhetoric in reviews published in two leading metropolitan journals, the paper offers evidence that the literary sphere contributed to the emergent culture of colonial legality.  相似文献

Lithium (Li) concentrations of produced water from unconventional (horizontally drilled and hydraulically fractured shale) and conventional gas wells in Devonian reservoirs in the Appalachian Plateau region of western Pennsylvania range from 0.6 to 17 mmol kg?1, and Li isotope ratios, expressed as in δ7Li, range from +8.2 to +15‰. Li concentrations are as high as 40 mmol kg?1 in produced waters from Plio‐Pleistocene through Jurassic‐aged reservoirs in the Gulf Coast Sedimentary Basin analyzed for this study, and δ7Li values range from about +4.2 to +16.6‰. Because of charge‐balance constraints and rock buffering, Li concentrations in saline waters from sedimentary basins throughout the world (including this study) are generally positively correlated with chloride (Cl), the dominant anion in these fluids. Li concentrations also vary with depth, although the extent of depth dependence differs among sedimentary basins. In general, Li concentrations are higher than expected from seawater or evaporation of seawater and therefore require water–mineral reactions that remove lithium from the minerals. Li isotope ratios in these produced waters vary inversely with temperature. However, calculations of temperature‐dependent fractionation of δ7Li between average shale δ7Li (?0.7‰) and water result in δ7Liwater that is more positive than that of most produced waters. This suggests that aqueous δ7Li may reflect transport of water from depth and/or reaction with rocks having δ7Li lighter than average shale.  相似文献

This paper describes Phase 1 of the project ‘Archaeological Applications of the Joint Irish Bathymetric Survey (JIBS) Data’, analysing bathymetric and backscatter data derived from multibeam surveys off the north coast of Ireland. In particular, the usability of the data for shipwreck detection, identification and site characterization is explored. In Phase 1, the data was screened for anomalous sea‐bed features, which were subsequently described, catalogued and categorized according to their archaeological potential and cross‐referenced against existing records. A planned second phase of this project will examine each anomaly in greater detail together with the local and regional hydrodynamic conditions. © 2010 The Authors  相似文献

Revisiting the theoretical roots of the key concepts of “embeddedness” and “networks” that underpin many recent regional innovation polices, this paper strives to achieve a more systematic understanding of the overall network structure of geographic agglomerations, which helps to form a more convincing model of regional development based on learning. This also helps to establish an analytical framework with indicators to assess the overall network structure in regional innovation policies. Employing the framework, the examination of cluster policy in the West Midlands highlights its weakness in addressing the overall cluster network structure and the contingent factors influencing the structure. The analysis suggests that there may be similar weaknesses in other regional innovation policies and the theories underpinning them as they share a common weakness in addressing the structural characteristics of overall networks.  相似文献
