Tectonic evolution of a Paleozoic thrust fault influences the hydrogeology of a fractured rock aquifer,northeastern Appalachian foreland

In polyorogenic regions, the superposition of structures during a protracted tectonic history produces complex fractured bedrock aquifers. Thrust‐faulted regions, in particular, have complicated permeability patterns that affect groundwater flow paths, quantity, and quality. In the Appalachian foreland of northwestern Vermont, numerous bedrock wells that are spatially related to the Paleozoic Hinesburg thrust have elevated naturally occurring radioactivity and/or low yields. The association of groundwater quality and quantity issues with this thrust was a unique opportunity to investigate its structural and hydrogeologic framework. The Hinesburg thrust juxtaposed metamorphic rocks of the hanging wall with sedimentary rocks of the footwall during the Ordovician. It was then deformed by two orthogonal Devonian fold sets and was fractured during the Cretaceous. Median well yields in the hanging wall aquifer are significantly lower than those of the footwall aquifer, consistent with the respective permeability contrast between metamorphic and carbonate rocks. For wells drilled through the Hinesburg thrust, those completed closest (vertically) to the thrust have the highest median yields, whereas others completed farther below have yields in the footwall range. The geochemical signature of the hanging wall and footwall aquifers correlates with their whole‐rock geochemistry. The hanging wall aquifer is enriched in alpha radiation, Na+K‐Cl, Ba, and Sr, whereas the footwall aquifer is enriched in Ca‐Mg‐HCO₃ and alkalinity. Wells that penetrated the Hinesburg thrust generally have hanging wall geochemical signatures. A simple hydrogeologic model for the permeability evolution of the Hinesburg thrust involves the ductile emplacement of a low‐K hanging wall onto a high‐K footwall, with subsequent modification by fractures.     

Tony Abbott and Abortion: Miscalculating the Strength of the Religious Right

In the context of analyses of the rise of the religious right, this article examines the passage and outcomes of the ‘abortion debate’ from 2004 to 2006. It analyses the reasons for the then Health Minister Tony Abbott's pursuit of the issue, and his strategies to place abortion on the public agenda, through his encouragement of church lobbies and conservative allies in parliament. Although it is commonly argued that the influence of right-wing Christian lobbyists is growing, this exploration of the abortion debate indicates that this influence is limited, and that it was misunderstood and overstated at the time by politicians like Abbott, and by many political commentators.     

Eric Voegelin as a Teacher's Teacher

ABSTRACT

Eric Voegelin was never interested in forming a school—his quest for truth was so Socratic that the last thing he wanted was people simply commenting on his own work. At the same time, his approach to the key texts of Western experience—and in his later years, of Eastern and archaic Neolithic and Paleolithic—blazed the way for his readers to get out there into that wide field of the human quest for transcendence and expand on his work in their own way. What this essay attempts, however sketchily, is to record his impact on my own teaching, with five samples of Voegelin-inspired courses I've developed. I begin with headlines from a philosophical effort at articulating an Irish Neolithic experience at Newgrange (3200 BC)—elsewhere, and following Voegelin, I've pushed that work back through Lascaux to Chauvet (32,000 BC). Then a brief mention of a Voegelinian reading of the beautiful Hindu Bhagavad Gita, followed by interpretations of Dostoevsky and Solzhenitsyn, and finally, a critique of Richard Dawkins' God Delusion. While, over the years, my classes also expanded on The World of the Polis and Plato and Aristotle, what Voegelin always seemed to demand was for us to engage in what he calls ‘the quest of the quest,' rather than simply repeat him. That's why I see him as the teacher's teacher: he wanted you, as a philosophy lecturer, to get on with your own search, and to awaken in your students what he called ‘the Question as a constant structure in the experience of reality.’     

Beyond Mainstream Approaches to Political Participation: A Response to Aaron Martin

Aaron Martin's (2012) recent article is the first to use survey data to compare the political participation of young people with that of older age groups in Australia. As such, it adds to our empirical knowledge of political participation, particularly by emphasising the changing focus of young people's engagement. Yet, like most mainstream, and especially quantitative, political participation researchers, Martin does not engage adequately with the growing, more critical literature). This response raises some of the issues emphasised in this literature, relating them directly to Martin's contribution. It has four sections: firstly, a brief consideration of Martin's main conclusions; secondly, a discussion of putative reasons for the change in forms of participation; thirdly, a consideration of broader forms of political participation; and finally, a consideration of the relationship between identity and political participation, which is at the core of most broader discussions of the latter.

阿隆·马丁（2012）在最近的文章中首先使用调查资料对澳大利亚年轻人和更年长者的政治参与做了比较。他的研究,特别是关于年轻人参与焦点的转移那部分,丰富了关于政治参与的实证知识。但与从事政治参与的主流尤其是定量研究的学者一样,马丁对于正在出现的、批判性的文献缺乏足够的关注。本文根据这些文献提出跟马丁研究相关的问题。本文包括四个部分：1）简要评述马丁的主要结论;2）讨论参与形式变化的推定原因;3）思考更为宽广的政治参与形式;4）思考身份与政治参与之间的关系,那是在更大范围内讨论政治参与的核心问题。     

US-China relations after 11 September: a long engagement or marriage of convenience?

This article traces the evolution of US–Sino relations in the period since the 11 September attacks on the World Trade Centre and the Pentagon. It argues that the resultant, largely unanticipated rapprochement that has occurred between Beijing and Washington is actually more robust than many analysts have thus far been prepared to acknowledge. While conflictual elements will remain a feature of this all-important bilateral relationship, the article contends that the current ‘honeymoon period’ in US–Sino relations is likely to persist for some time yet, largely because it is underwritten by a deeper combination of economic, political and strategic considerations. While recognising that it is both natural and necessary to contemplate the ‘worst of times’ that may still lie ahead in US–Sino relations, the article concludes that it is particularly important for Australian policymakers to acknowledge the potential for a prolongation of the post-11 September ‘honeymoon’ and to actively encourage this possibility as they contemplate alternative approaches to managing China's rise.     

Learning About Regionalism from Europe: ‘Economic Normalisation’ and Beyond

This paper critically analyses the European Union's regional policy framework and considers its implications for Australia's multi‐level governance system. The analysis is made with reference to the ‘new regionalist’ debates in Europe and North America that have asserted the importance of regional economic development in the context of globalisation. New regionalism's advocacy of ‘economic normalisation’ as a leading regional policy aim is critically evaluated against the EU policy experience. Conclusions about the adequacy of new regionalist claims are drawn for Australian policy debates.     

The Political Economy of Exile in the Great Dismal Swamp

The Great Dismal Swamp in North Carolina and Virginia has a history of profound significance to scholars and historians of North American diasporas. Between 1630 and 1865, thousands of maroons, enslaved canal company laborers, and disenfranchised Native Americans lived within this morass and formed communities that were connected through a dynamic swamp-wide political economy. The Great Dismal Swamp Landscape Study has been initiated to explore the archaeological landscapes of these Diasporans. This essay discusses several aspects of the theoretico-analytical research model that has guided this ongoing project. Also, included are brief explications on the methods and results of the first season of archaeological survey in the Great Dismal Swamp National Wildlife Refuge.     

Eliding the Esoteric: R. J. Campbell and Early Twentieth Century Protestant Discourse in Britain

R. J. Campbell was arguably the most renowned British religious figure of his generation, a prominent promoter of reform as a leader of non‐conforming Protestantism in Britain at the turn of the twentieth century. He is generally regarded as a promulgator of pre‐war optimism, a universalist who courted personal fame and who sparked an intra‐Protestant sectarian crisis when he initiated a new reformist movement, the “New Theology.” Most of the analysis, including Campbell's suspect retrospective memoir, treat this religious ferment as rooted in Protestant/Christian perturbation. This perspective does not allow for a wider consideration of the vibrant religious milieu of enquiry then in vogue which brought Campbell into contact with a variety of esoteric ideas and philosophies and their interlocutors. Absent this focus, important figures participating in that religious colloquy are marginalised. My article seeks to fill out the commonly accepted version of events. Material not previously examined is interrogated towards illuminating Campbell's wider interests. It postulates that Campbell was one of a number of contributors to a broad discussion on religious ideas and their relationship to Christianity, one of a number of figures shaped by, as much as shaping, the contemporary discursive environment.
