Ectopic paragonimiasis from 400-year-old female mummy of Korea

Of the parasite eggs discovered in ancient samples from Korean archaeological sites, Paragonimus spp. are of particular importance in that they are regarded as one of the most insidious trematode infection sources. Although their infection prevalence decreased rapidly in the early 20th century, archaeoparasitological studies on the species are still required, as historical knowledge of paragonimiasis remains far from comprehensive. Fortunately, we recently were given a chance to examine a medieval Korean mummy in a good state of preservation. Using morphological techniques, we discovered evidence of ectopic paragonimiasis in the sample from the 17th-century female. When the ITS 2 gene was extracted, amplified and sequenced from Paragonimus eggs, it showed 100% homology to the sequences of modern Paragonimus westermani reported from Korea and Japan, forming a cluster distinct from South Asian P. westermani. Our report is the first-ever analysis of ancient Paragonimus DNA from any archaeological field in the world. The ectopic paragonimiasis diagnosis made in this study, especially involving the liver sample, also is the first of its kind in archaeoparasitology.     

HISTORY,INSTITUTIONS, AND CITIES: A VIEW FROM THE AMERICAS*

ABSTRACT Every nation, formally or informally, defines and establishes the lines of political and fiscal authority among its national, regional, and local governments. Historically, centralized governments tend to restrict the power and autonomy of provincial and local governments. In this paper, we exploit the quasi‐experimental distribution of political institutions in the Americas caused by variation in European colonial experience to examine the impact of institutions on urban and local development, specifically on the degree of urban primacy, the size distribution of cities, the number and density of local government units, and the fragmentation of metropolitan areas. We argue that centralization of political power at the national level, as experienced in many countries in Latin America, contributes to urban primacy and a size distribution of cities favoring large cities. Additionally, even in more politically decentralized countries such as Canada and the U.S., variance in political centralization at the provincial (state) level over local governments led to significant divergences in urban primacy, the distribution of city sizes, as well as the form, number, and density of local governments. While we cannot rule out the importance of other factors, our findings suggest that political centralization affects spatial economic development.     

Class,Citizenship and Regeneration: Glasgow and the Commonwealth Games 2014

Abstract: Through a focus on “consumer‐citizenship” this paper foregrounds the class practices inherent in urban regeneration. Using Glasgow's 2014 Commonwealth Games (CWGs) as an illustrative example of regeneration, it seeks to highlight the market‐led processes that underpin state interventions. The paper demonstrates how these processes are implemented to transform “problem people, and problem places” ( Damer 1989 , From Moorepark to “Wine Alley”) into sites of “active” consumption and “responsible” citizenship. Yet, access to this “consumer citizenship” is stratified. In doing so, we synthesise conceptual insights from the Marxist‐influenced gentrification literature and the Foucauldian‐inspired housing renewal literature. We forward this to initiate further academic debate and empirical enquiry on the specific issue of mega sporting events.     

The Limits of Bonhoefferian Responsibility: On Jean Bethke Elshtain's (Mis)Use of Bonhoeffer

ABSTRACT

Jean Elshtain claims that her defense of torture draws from the Christian tradition. To defend this claim, she makes direct appeal to Dietrich Bonhoeffer. Her defense of torture has taken on greater political significance today. This article will refute Elshtain's claim to Bonhoeffer. To do so, this article will first point to Bonhoeffer's explicit rejection of torture in Ethics, then argue that Bonhoeffer's rejection of torture draws from themes initiated in Creation and Fall. Placing Bonhoeffer in conversation with David Decosimo will show that Bonhoeffer holds a distinction between relation-ending and relation-perverting acts. Responsible actors may be called to perform the former class of actions, like tyrannicide, in extraordinary situations. However, the latter class of actions, like torture or rape, constitutes a limit to responsible action that we find no evidence Bonhoeffer is willing to cross. Elshtain, and others who wish to provide “Christian” defenses of torture, must look elsewhere.     

CHANGES IN THE NATURE OF URBAN SPATIAL STRUCTURE IN THE UNITED STATES, 1890–2000*

ABSTRACT This paper documents the long‐run trends in the average densities and density gradients of urban areas in the United States. The data show that between 1890 and 2000 the average densities of cities and metropolitan areas rose and fell but that the density gradients of urban areas generally declined monotonically over time. While it is beyond the scope of this paper to estimate the causes of these changes, this paper argues that a complete understanding of the changes in the nature of US urban spatial structures is likely to go beyond the standard explanations based on the monocentric city model such as decreases in transportation costs and increases in household incomes.     

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.     

Rice,Ethnicity, and the Collation of Archaeobotanical Data for Prehistoric Korea

Nationalism and archaeology are universally and almost unavoidably intertwined. The multilevel influence of nationalism not only delimits the legitimate interpretations of archaeological data but also determines the retrieval, analysis and dissemination of data. This point is illustrated in the present study with a historical overview of archaeobotanical data collation at four prehistoric sites, two in North Korea and two in South Korea, that were excavated between 1957 and 1981. The paper examines the persistent and increasing archaeological interest since the early 1970s in the search for rice, a crop that constitutes an integral part of the Korean ethnic identity. The remains of rice have tended to receive more scholarly attention, be subject to extended discussion, and be more widely publicized, compared to the relatively neglected research on the remains of other “miscellaneous” crops. This demonstrates that botanical remains from archaeological sites, often presented as an outcome of scientific scrutiny, are a social product and that greater attention needs to be paid to local archaeological concerns before the data are compared internationally or across different research traditions.     

Mössbauer Spectroscopic and Chromaticity Analysis on the Colourative Mechanism of Ancient Goryeo Celadon from GangJin and Buan

In ancient Goryeo celadon excavated from the kiln sites in the GangJin and Buan areas, the effect of the chemical composition and ionic state of Fe on the colour was evaluated by Mössbauer spectroscopy and chromaticity analysis. According to chromaticity analysis, the L* value (brightness) of the glaze was shown to be affected more by TiO₂ and MnO than by Fe₂O₃, and the body was affected more by Fe₂O₃ than by TiO₂. The a* value was found to be affected by Fe₂O₃ and TiO₂ in the glaze, whereas there was hardly any change in the body according to the composition. As for the b* value, changes due to the composition were shown to be smaller than those for the L* and a* values. According to the Mössbauer spectroscopy results, as the quantities of TiO₂ and Fe₂O₃ are increased, Fe²⁺/Fe³⁺ decreases; while the changes in Fe²⁺/Fe³⁺ with MnO and P₂O₅ are negligible. As the quantity of Fe²⁺/Fe³⁺ increases, the a* and b* values decrease, which results in the change of colour from red–yellow to blue–green. The characteristic green colour can be attributed to increased L* (brightness) and decreased a* and b* values (blue–green shift) due to the reduced Fe ion, which is mainly determined by the TiO₂ and Fe₂O₃ contents.
