This article explores the implications of the Judeo-Christian tradition's influence on the United States for the foreign policy of an American Christian Democratic Party. If there were to be such a party in the United States, it would not have to create a new set of ideas and principles out of whole cloth. In fact, an articulation of an American Christian Democratic foreign policy would largely consist of an effort of resourcement, rediscovering and applying anew foundational principles at the core of the American experiment. This article develops this insight in two main foreign policy areas: national security and economic. 相似文献

Recent museological scholarship emphasises visitor participation and democratic access to cultural heritage as key to securing the ongoing relevance and future sustainability of museums. But do legacies of colonialist collecting practices and hierarchical conventions of representation in museums afford the possibility of genuine cultural democracy? This paper explores this question via detailed analysis of the Encounters exhibition, developed by the National Museum of Australia in partnership with the British Museum and promoted as an unprecedented partnership between the institutions and Indigenous Australian communities. Drawing on an extensive and emerging literature on museums, community engagement, participation and democracy, in tandem with analysis of public critiques and Indigenous responses to the exhibition, the paper suggests that the extent of Indigenous agency within the collaboration fell short of the articulated goals of the project. It concludes that the concept of maximal participation and release of agency to communities of interest may be difficult to achieve within existing museum frameworks. 相似文献

ABSTRACT We take advantage of an unusual natural experiment—a high‐quality 1920s subdivision split neatly in half by a central‐city/suburban boundary—to study the response over 30 years to the relative decline in the quality of central‐city services since the 1960s. As expected, a large sale price differential opens in the 1960s. Demographic characteristics are nevertheless similar across the boundary. Survey data indicate Tiebout sorting: the central city side attracts households who prefer alternatives to suburban public schools. Children attend parochial and public “magnet” schools. A neighborhood association supplements municipal services. Rigid service district boundaries inhibit closure of the house‐price differential. 相似文献

ABSTRACT We revisit the influential work of Borjas (1995) on the economic gain to the host population from immigration—“the immigration surplus.” We develop his analysis by using a general equilibrium endogenous growth model with endogenous capital and several sectors, including an R&D sector driving growth. Skilled immigration leads to a bigger R&D sector share resulting in higher long‐term growth. If skilled labor and physical capital are complements, this growth gain increases. Growth effects on the immigration surplus dominate the purely static effects of Borjas, but are not sufficient to eliminate the emergence of losers (skilled natives) within the host population. 相似文献

This article reflects on a politics of hope, silence and commonality through some extended conversations with members of the public during a demonstration which shut down an oil refinery in Nottingham. My reflections concern the concept of uncommon ground, where there are encounters between activists and their others. While conversations on uncommon ground highlight the entrenched nature of many social roles, possible connections open up by highlighting how they are always emotionally laden, relationally negotiated, hybrid, corporeal and contingent. Hence, the paper addresses the potentialities for extending dialogue on uncommon ground into common places. A key element relates to the need to transcend the role of the activist, to literally give up activism. This article builds upon normative, participatory and libertarian approaches in Geography which propose what could become possible by working with others towards mutual aid and self‐management. In essence, learning to walk with others helps us to counteract universalist solutions and instead assemble toolkits for developing contextualised and workable alternatives to life under capitalism. 相似文献

Using an original and unique database of state charter school laws that we have developed, we analyze how state policymakers have incorporated two key values into state charter school laws: flexibility and accountability. We supplement this database with other state‐level measures to answer two specific questions: What factors influence the degree of flexibility and accountability in state charter school laws? How does the content of state charter school laws, and the different values those laws embrace, affect the formation of charter schools in the United States? Overall, we show that state political and contextual factors help account for the degree of flexibility, but not accountability, in state charter school laws. Further, we show that the degree of flexibility, accountability, and political and contextual factors influence the number of charter schools that form in the states. 相似文献

Obsidian sourcing based on geochemistry is widely applied to reconstruct commerce patterns and dissemination of early hominid groups. Due to problems concerning potential intra-source variability or homogeneity of a geological source over large areas, parameters additional to this classical approach are desirable. Here we present the first 40Ar/39Ar investigation of Middle Stone Age (MSA) obsidian artifacts (i.e. debitage pieces) for this purpose, as well as of potential geological obsidian sources from Ethiopia. With the present pilot study we demonstrate that 40Ar/39Ar geochronology represents a reliable and powerful tool for archaeological provenance studies complementary to the geochemical approach and more recently applied techniques like fission track counting or Mössbauer spectroscopy. Two independent sets of debitage and potential source rock samples were dated by the 40Ar/39Ar method. Debitage pieces from the Kulkuletti excavation site and obsidian samples from the nearby obsidian outcrop Worja (central Ethiopia) exhibit basically identical age ranges as well as similar Ca/K and Cl/K ratios, supporting the debitage/source rock relationship previously inferred on geochemical grounds. A second small set of geochemically characterized debitage samples from the Porc Epic cave and potential source rocks from an obsidian outcrop at Kone (Eastern Ethiopia) however have different 40Ar/39Ar ages and Ca/K and Cl/K ratios. These results contradict the previous conclusion about a debitage/source rock relationship of the Porc Epic and Kone samples made on the basis of geochemistry [A. Negash, M.S. Shackley, Archaeometry 48 (2006) 1]. Additional sampling at the Kone outcrop as well as of other obsidian occurrences in the greater area is needed to unambiguously pinpoint the origin of these obsidian tools. 相似文献

The Greens at the 2004 Queensland State election almost trebled their primary vote from 2001, an increase suggesting the party has already filled the vacuum left by the declining Australian Democrats as the State's principal Left-of-Centre minor party. This article argues, first, that much of this growth in support can be attributed to the substantial interstate migration to the State's southeast, a pattern that has contributed to a partial transformation of Queensland's traditional political culture to one more disposed to Green support. Second, given that this growth is set to continue, it is argued that the Queensland Greens are yet to maximise their vote. This article analyses the 2004 Queensland State election results to determine the impact of Green preferences under the State's Optional Preferential Voting (OPV) system, and to locate where geographically, and among whom demographically, Green support was strongest. A rudimentary profile of the ‘typical’ Queensland Greens voter is also offered. 相似文献
