Fragments of charcoal are present in floodplain alluvium of the San and Strwi?? rivers in the Polish part of the Bieszczady Mountains, Polish East Carpathians. They occur as single clasts or in lenses in the basal part of fine-grained alluvium, together with unburnt wood debris, or in the middle part of the vertical sequence of the floodplain alluvium. 14 samples of charcoal from the upper courses of the San (ca. 50 km) and the Strwi?? (ca. 10 km) were dated with radiocarbon. The obtained dates fall mainly in the 15th through 19th century interval; only one sample is markedly older (9th–10th century). Taxonomic composition of the charcoal source wood was also studied and compared with that of coeval forests. Correlation of the charcoal age with the history of economic development of the studied region indicates that charcoal is of anthropogenic origin: older charcoal from intense slash-and-burn deforestation, while younger charcoal was produced by local industries. 相似文献

The purpose of this article is to explain and discuss the essential operational characteristics of the technology of power
(sensu Foucault) perpetrated on the internal frontiers with the Indians in nineteenth-century Argentina. The conquest and
colonization of the Pampas took shape in the establishment of military camp structures placed to create a defensive cordon,
known as “the Indian frontier line.” These constructions were fortlets defended by gaucho cavalry squadrons (know as Blandengues
during the Spanish period, and then Guardias Nacionales after Argentinean Independence). This process is known in Argentinean
historiography as “the conquest of the desert.” This particular technology of power existed in this historical context and
operated at every social level, impacting strongly on the lower classes that inhabited the incorrectly named “desert.” Its
implementation in the military field enabled the existence of an array of micro-powers that surrounded the gaucho, called
vago y malentretenido—“a vagrant and lingerer”—and their women's lives. The army as institution was the locus of various forms
of coercion and old forms of punishment (such as the stakes, whipping, and public executions) most of which affected peasants,
nonresidents, itinerant workers, and the rural youth. This schema was adopted in different areas: in the enrolment and discipline
of the gaucho soldiers, in life in the fortlet-prisons, and in the ritualism of power. The alternative chosen by soldiers
to evade this technology of power and the fortlet-panopticons was escape through desertion. The utility of those observations
is demonstrated, because an important part of the area of research of historical archaeology that has developed with the greatest
impetus in Argentina has taken fortlets as its subject of study. 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

A small iron gun recovered from the wreck of the Caroline warship Swan has been identified as a drake, a lightweight tapered-chamber design dating from the 1620s. It is the only known cast-iron example of such a piece made by John Browne, gunfounder to Charles I, who was the leading figure in its development and manufacture in England. The gun was found together with an associated carriage, port-lid, and case shot appropriate to its calibre.

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that
contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some
of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are
semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls.
Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the
Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This
designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures,
we analyze a group of 4 that were excavated to use to review the written documents. 相似文献

The questions addressed in this paper are: (i) does wage inequalityincrease with local population size, and if so, (ii) what arepossible factors behind this increase? In a cross-section analysisof Swedish local labour markets using unique full populationdata, the article shows that urban scale, i.e. size of localpopulation, has significant positive effects on wage inequality.Testing for potential explanations, labour market diversification,human capital, migration, age structure and employment are shownto be significantly associated with inequality. Given theseeffects, the article raises the question of how to understandand incorporate scale effects into models of long-term changein wage inequality. 相似文献

In the context of education in England, an argument is put forward that Geography, as it is conceptualised in the National Curriculum, does not connect to either primary school pupils or their teachers. Reasons for this are explored and a proposal is made for a new paradigm for primary geography: ethnogeography. This proposal parallels work on ethnomathematics, which provides a political agenda to the study of maths and itself draws from Paulo Freire's politicization and consciousness raising through adult literacy. This pattern is applied to learning in geographical education. Drawing on the findings of a recent research project, a case is argued for ethnogeography and the implications for primary Initial Teacher Education courses, learners and the curriculum in primary schools and are considered. 相似文献
