Research into the family of the Counts Swéerts-Sporck raised doubts regarding their biographical data, particularly concerning a child who died in 1817, later identified as Philipp Swéerts-Sporck, and his siblings Joseph and Barbara. These were alleged to include a pair of dizygotic twins, but DNA could not be used to clarify their relationships. Carbon and nitrogen isotopes were therefore measured in their first permanent molars, whereas Philipp's biological age was estimated based on his skeleton. Philipp died at an older age than the written sources claim; an isotopic similarity was found between Joseph and Barbara, but Philipp differed.  相似文献

City districts are often classified as ‘rich’ or ‘poor,’ a phenomenon that occurs within cities all over the world. While income inequality, wealth inequality, and other kinds of social inequality are frequently tracked, there is a surprising lack of research concentrating on how social inequality manifests as differences between parts of cities, especially outside of the U.S. That is mostly due to insufficient available data. In this paper, we propose a methodology for measuring the relative inequality between city districts by using the average prices of residential properties in various parts of the city, and assessing their relative difference. This approach has several advantages, as property listings are often readily available even in cities where income data is not. This methodology has potential for measuring developments in inequality in a much wider range of cities. As a proof of concept, we apply this methodology to property prices in Prague during the period 2003–2012 to identify a trend of either growing or decreasing inequality among individual parts of the city. We have found that during this period the disparity has grown only 5.97%, which means the overall growth of disparity between the city districts was negligible.  相似文献

The leprosy known today primarily from tropical areas was a relatively common disease in European Middle Ages. This article describes two skeletons bearing palaeopathological indications of leprosy from a cemetery at ?atec in North-West Bohemia (Czech Republic). The archaeological context clearly shows that these individuals were buried prior to the second decade of the 12th century, and most probably in the second half of 11th century. This rules out the possibility that these individuals might have contracted the disease in connection with the Crusades, in which a Bohemian contingent under Prince Vladislav II participated from 1141 to 1142. Molecular genetic methods were applied to detect specific DNA fragments of the causative agent of leprosy, Mycobacterium leprae. The nasal concha of one individual yielded DNA that could be directly sequenced after isolation and amplification. The vertebral body of the second individual, on the other hand, did not provide DNA of sufficient quality for direct sequencing and only weak amplification was detectable. The morphological and genetic analyses both indicate that leprosy existed prior to the Crusades in medieval Bohemia, albeit that its prevalence was probably not as great as in northern or western Europe.  相似文献

The objective of this paper is to assess the relationship between the cereals cultivated in the Late Bronze and Early Iron Ages (ca. 1250–400 BC) within the area of the present-day Czech Republic, and their environmental settings. The various charred caryopses of cereal species represented in the archaeobotanical assemblages from 35 archaeological sites differ, especially in the proportion of wheat and barley. The cereal assemblages were compared regarding site altitude, weather conditions, soils and soil productivity. The most important environmental variable influencing the choice of a particular crop seemed to be altitude which is correlated with other variables such as the length of growing season, mean annual temperature, soil quality etc. Although the ecological requirements of cereals cultivated in the Late Bronze and Early Iron Ages are not known, they presumably thrived under similar conditions to present-day species/varieties, and the strategy of past crop husbandry was based on similar principles as today, e.g. flexible adaptation to local environmental conditions, in an effort to achieve optimal yields and reduce the danger of crop failure.  相似文献

This paper uses firm‐level data to examine how supply chain networks affected the recovery of firms from the Great East Japan Earthquake. Extensive supply chains can negatively affect recovery through higher vulnerability to network disruption and positively through support from trading partners, easier search for new partners, and general benefits of agglomeration. Our results indicate that networks with firms outside of the impacted area contributed to the earlier resumption of production, whereas networks within the region contributed to sales recovery in the medium term. The results suggest that the positive effects of supply chains typically exceed the negative effects.  相似文献

There are several hundred recorded Early Upper Palaeolithic sites in Moravia, most of which are surface sites. The majority were exposed by agricultural plowing and subsequently discovered by pedestrian surveys whereas most of the stratified sites were found accidentally. Numerous unsystematic attempts in the past to find stratified remnants of sites disturbed by plowing have been unsuccessful. Here we present a methodology for locating stratified Early Upper Palaeolithic cultural contexts based on distribution of surface scatters. This involves pedestrian surveys guided by background research. All Palaeolithic artifacts were recorded using a handheld GPS with particular attention to calcium carbonate crust on artifact surfaces, which can be indicators of nearby stratified deposits. Exploratory test pits were then excavated followed by systematic excavations if the potential for stratified cultural deposits was deemed high.

Using this technique, we have discovered 11 new stratified Early Upper Palaeolithic sites.  相似文献

Among the avowed social policies of the Soviet Union are modernization and industrialization, which may be combined under the label of Sovietization, and the spread of Russian language and culture within the USSR, which may be termed Russianization. But there is also a third process at work in which non-Russians lose their ethnic identity in favor of identification with Russian culture. This process, which may be called "Russification," can be measured by the number of non-Russians who declare Russian to be their first language in the census. The authors use correlation analysis and principal components analysis to identify the factors that promote or hinder the Russification process.  相似文献

European Union (EU) funds flowing into budgets of public sector organizations of its member states should be additional to their nationally funded expenditures. To investigate this additionality principle systematically, we develop a new empirical method. Our main hypothesis is that some of the EU-funded projects are crowding out national public expenditures. Not being able to reject the hypothesis would be consistent with violating the additionality principle. To test the hypothesis, we examine how EU funding translates into actual spending of relatively comparable municipalities of the Czech Republic. We innovatively match the municipal authorities’ budgetary data on EU-funded expenditure projects with their other, nationally funded, expenditures. We find no systemic crowding out of national public expenditures by EU funds at the level of operational programmes in the Czech municipalities’ data, which is consistent with no evidence of violating the additionality principle. Nonetheless, going down to the municipal level enables us to show how the results can pinpoint individual cases of EU fund’s potential mismanagement in Czech municipalities. Overall, we provide the first evaluation of the additionality principle at the level of individual recipients of EU funds and in doing so we develop a methodological approach potentially applicable to other fund recipients.  相似文献
