Amplification and sequencing of Trichuris trichiura ancient DNA extracted from archaeological sediments

Despite high prevalence of Trichuris trichiura infection, PCR-based analysis on T. trichiura from archaeological samples has not been established so far. In the present study, we sought to perform PCR-based amplification of T. trichiura aDNA using the sediments from medieval tomb of Korea. The presence of Trichuris eggs were first detected by microscopic observation; then confirmed by PCR-based aDNA analysis. Obtained sequence showed 100% homology to that of the small subunit ribosomal RNA (SSUrRNA) gene of T. trichiura but distinct from that of other Trichuris species. PCR-based aDNA analysis in this study can serve as effective method to confirm the presence of T. trichiura eggs in the soils or coprolites collected from archaeological sites.     

Mad cow militancy: Neoliberal hegemony and social resistance in South Korea

Massive protests shook South Korea through the summer of 2008. This political eruption which exhibited many novel and unexpected elements cannot be explained by pointing to basic political conditions in South Korea (strong labor unions, democratization, and so forth). Neither does the putative reason for them – to protest the new President’s decision to reopen South Korea’s beef market to the U.S. – adequately explain the social dynamics at play. In this paper, we examine the political geography of the ‘candlelight protests’ (as they came to be known), focusing in particular on their novel aspects: the subjectivities of the protesters, fierce ideological struggles, and differentiated geography. We argue that the deepening of neoliberal restructuring by the new conservative regime formed the underlying causes of these intense conflicts. In other words, the new protests should be seen as a response to the reinforced contradictions engendered by neoliberalization and a new alignment of social groups against the prevailing hegemonic conditions in South Korea. In this view, the huge demonstrations revealed vulnerabilities in conservative hegemony but failed to produce a different hegemony. To advance these claims, we examine three aspects of the protests: first, the neoliberal policies of the new conservative regime; second, the intense ideological conflicts around the media; and finally, the spatial materialization of the protests.     

The corporeal,the social and space/place: exploring intersections from a midwifery perspective in New Zealand

This article explores the interrelations between the corporeal, the social and the spatial as they operate to shape the discursive and material realities of childbirth in the obstetric hospital setting. It draws on interviews conducted with midwives throughout New Zealand and embodies key insights derived from the work of Michel Foucault and Elizabeth Grosz. The obstetric hospital is theorised as a product of particular socio-political relations that privilege biomedical constructions of the body and childbirth. Midwives, however, proffer an alternative construction of childbirth and the space/place it is enacted. It is one that requires a woman to actively engage with a variety of birth spaces and take up a range of subject positions that enable her to be a more active agent in the process of parturition. The limited and limiting spatial and discursive arrangements of the obstetric hospital, it is argued, shape the behaviour, subjectivity and corporeality of the maternal body confined within it and therefore the practises of midwives. Unfortunately, and as this article demonstrates, the opportunity to take up such an alternative is limited in the obstetric hospital despite some recent cosmetic attempts to render it more welcoming.     

Testing for Regional Differences in Means: Distinguishing Inherent from Spurious Spatial Autocorrelation by Restricted Randomization

Tests for differences among regional means are typically carried out by analysis of variance (ANOVA). When such data are spatially autocorrelated (SA), the assumptions of ANOVA are not met, giving rise to excessive type I error rates. Two spatially adjusted ANOVA methods, Griffith's and COCOPAN, have been proposed to overcome this problem. In this study we show, by means of extensive simulations, the magnitude of the error rates introduced by SA induced in isolation-by-distance models typical of those used in population genetics. For data suspected of exhibiting such SA, we propose a strategy for distinguishing between inherent SA, generated within the data by a contagious process, and spurious SA, introduced by regional differences in means. The approach adopted is that of restricted randomization of distance matrices. We also furnish error rates and power estimates for both Griffith's method and COCOPAN. In addition to the simulated data, the methods are applied to an actual example from plant population biology.     

Industry Characteristics Linked to Establishment Concentrations in Nonmetropolitan Areas

In this paper we investigate industry characteristics associated with the clustering of establishments in three-digit SIC manufacturing industries in nonmetropolitan areas. The dispersion parameter k of the negative binomial distribution is selected as the measure of industry spatial concentration. Associations between industry characteristics and spatial concentration are investigated using OLS regression analysis. Our findings indicate that the spatial clustering of establishments is positively related to industry average establishment size, reliance on natural resource inputs, labor intensity, cost shares of professional and technical employees, and cost shares of low-skilled workers. Agglomeration is negatively related to multiplant structure, employment in precision production, and reliance on local product and input markets.     

New insights into Mao’s initial strategic consideration towards the Korean War intervention

The argument that the US army’s crossing of the 38th parallel compelled China’s intervention has been widely accepted in the West. However, as the US manoeuvre posed a major threat to the political and ideological foundations of the CCP regime in the early period of the Korean War, Mao Zedong wanted to send troops to assist North Korean’s quick victory. However, this was not realised because of Stalin’s negative position. Mao’s stance shows that his overriding criteria for intervention was not whether US forces would cross the 38th parallel, but whether their dispatch helped to solidify the CCP regime and if the preconditions for victory existed.     

Performing Rootedness in the Negev/Naqab: Possibilities and Perils of Competitive Planting

Through ethnographic and historical analysis of the Negev region of Israel, this article examines competitive planting as a common tool in land conflicts. In a context of disputed land ownership, some Bedouin Arab residents plant crops in defiance of government policy. Government enforcers of land‐use regulations destroy many of these crops and engage in counterinsurgent tree‐planting. I suggest that planting is such a potent tactic because it draws on “environmental idioms” of agricultural labor, the rootedness of trees, and a fundamental Jewish‐Arab opposition that have been central to the development of both Israeli and Palestinian nationalisms. For Bedouin Arabs, whose relationship to both nationalisms has long been contested, the multivalent symbolism of planting makes it a particularly promising tactic for asserting land claims. Further, I contend that these plantings demonstrate both the power of environmental idioms to structure land claims along ethnic lines and the creative potential of participants to challenge dominant environmental discourses by adding new connotations.
