Thirteen burials located on Jackson Street in Youngstown, NY, USA were recovered from a construction site and excavated in 1997. Based on the artifact assemblage, it was suggested that the cemetery was used sometime between the late 1700s and 1840. No historical records existed, and initial assessment of the skeletal remains was not able to determine any cultural affiliation. We carried out osteological and genetic investigations in order to gain insight into ancestral affiliation and kinship of the unknown individuals from the burials. Due to poor preservation of the remains, dental traits and limited osteological observations were available for only a few individuals. We performed DNA extraction and sequenced the mitochondrial DNA (mtDNA) control region following standard ancient DNA procedures. Our results suggest that ten individuals have evidence of biological affiliation with Native Americans, and in particular, four individuals have maternal Native American ancestry. One male individual was determined to be of European ancestry, from both the mtDNA and osteological results. This burial may reflect admixture as a result of frequent contact between Native Americans and Europeans during the eighteenth and nineteenth centuries and attempts by missionaries to convert Native Americans to Christianity. Our study demonstrates the usefulness of a multifaceted approach through archaeological, osteological, and genetic analysis that provides valuable perspectives in understanding the individuals buried at the Jackson Street Burials. 相似文献

ABSTRACTChallenging the widespread assumption that “political theology” as a discipline began with Carl Schmitt in the 20th century, this essay explores the biblical theme of God’s preferential option for the poor and oppressed first articulated as a modern political theology by Latin American theologians, but organically and independently manifest in US black liberation theology, and First World feminist theologies. At the heart of this movement is a commitment to speak truth to power at the risk of personal loss and even martyrdom. 相似文献

Current research in the Mixteca region of Mexico has revealed that Formative communities were as populous as in other Mesoamerican regions. Evidence of emerging social complexity is associated with the use of and access to luxury items of foreign style and/or manufacture. Research efforts draw from indigenous models to interpret data and investigate urbanism. Regional and environmental approaches, household studies, and ethnohistory are integrated to study ethnic diversity and the complex history of human occupation. The politics associated with cultural resource management and community archaeology in the Mixteca also are discussed. 相似文献

Liang Bua is a limestone cave on the island of Flores, Indonesia. Palaeontological and archaeological excavations at this site have unearthed one of the best insular records of fossil bats to date. The assemblage is numerically dominated by the horseshoe bat species Rhinolophus euryotis, followed by the leafnosed bat Hipposideros diadema. In addition to these species, remains of Rhinolophus simplex, Hipposideros sp. cf. H. sumbae, Murina sp. aff. M. florium, Taphozous sp., Kerivoula sp. and Miniopterus sp. have also been recovered. Two taxa found in Liang Bua, Rhinolophus euryotis and Miniopterus sp., are not apparent in the modern bat fauna of Flores. Some specimens, found during the more recent excavations, are known from specific depths. Two age-groups are represented. The stratigraphically oldest is 74–61 ka and includes Murina sp. aff. M. florium and Rhinolophus euryotis. Conversely, the younger, Holocene, assemblage is much more diverse. Despite the relatively small amount of microbat material collected thus far, it displays a higher diversity than the rodents from the site. This is presumably related to the better dispersal ability of bats relative to other, non-volant mammals. 相似文献

Abstract. This paper models externalities of production across regional economies. Under the assumption that knowledge diffuses without political or administrative barriers, we derive externalities that affect the steady state and the process of growth of each economy. The empirical counterpart of the reduced form equation summarizing the process of growth allows us to test for the presence of regional spillovers and to measure their magnitude. Our results for a sample of European regions show that spillovers are far from negligible, are robust to the consideration of variables within each region, and may cause nondecreasing returns at the spatial aggregate level. The paper also relates previous empirical evidence on spatial dependence in growth studies to the externalities modeled here. 相似文献

A new method called the Baseline Stiffness Method (BSM), used to locate and quantify damage in buildings without baseline modal parameters (undamaged state), is presented. In order to determine this reference state, the BSM uses modal parameters from the damaged state of the building and the lateral stiffness matrix of the first story without damage. Afterwards, by means of an iterative process using singular value decomposition, location and severity of damage are obtained by comparing information about the damaged and non damaged states. Numerical and experimental examples are presented and discussed showing the advantages of the application of the proposed BSM. 相似文献

Peering through the lens of illegal charcoal production in the forested areas of Virunga National Park in eastern Democratic Republic of the Congo, this paper makes a case for disaggregating the notion of “the state” to better capture “the political” in contemporary political forests. It argues that to identify the fluctuating importance of different dimensions of “stateness”, it is crucial to acknowledge the polymorphous socio-spatial relations that produce political forests. Thus, we draw on the notions of territory, place, scale and network (TPSN) to examine how “stateness” in Virunga has transformed under the particularisation, transnationalisation, and regionalisation of authority. This approach allows us to show how these processes do not only stem from neoliberalisation, but are also driven by, inter alia, regional warfare and non-state militarisation. The resulting complexity of the regulatory landscape turns Virunga into a space marked by a plurality of partly overlapping and partly conflicting political forests. 相似文献

We analyze the firm-level labor productivity growth returns of social capital—defined as a synthetic measure of “generalized trust,” “active participation,” and “social norms”—using a large sample of manufacturing firms in France, Germany, Italy, Portugal, and Spain. We find that firms' labor productivity growth is higher in areas with a better social capital endowment. The positive returns of social capital are, nevertheless, unevenly distributed across firms, with smaller, less productive, less capital-endowed, and low-tech firms benefitting the most from operating in strong social capital ecosystems. 相似文献

GOVERNMENT QUALITY AND THE ECONOMIC RETURNS OF TRANSPORT INFRASTRUCTURE INVESTMENT IN EUROPEAN REGIONS 下载免费PDF全文
Riccardo Crescenzi Marco Di Cataldo Andrés Rodríguez‐Pose 《Journal of regional science》2016,56(4):555-582
Transport infrastructure investment is a cornerstone of growth‐promoting strategies. However, the link between infrastructure investment and economic performance remains unclear. This may be a consequence of overlooking the role of government institutions. This paper assesses the connection between regional quality of government and the returns of different types of road infrastructure in the regions of the European Union. The results unveil the influence of regional quality of government on the economic returns of transport infrastructure. In weak institutional contexts, investment in motorways—the preferred option by governments—yields significantly lower returns than the more humble secondary road. Government institutions also affect the returns of transport maintenance investment. 相似文献
