The early sedimentological and ecological developmental stages of a late Vistulian lake in the ?abieniec swamp near ?ód? (central Poland) were analysed by radiometric dating, changes in the frequency of specimens and species composition of Cladocera and multivariate statistical analysis (DCA). The longevity of the lake resulted in a fairly complete sedimentary record from approximately 22 ka to 11 ka cal BP. Species composition and the variability in the frequency of Cladocera specimens has made it possible to distinguish eleven zones of their development, which are well correlated with radiocarbon data. The results were compared to those from other sites of north and central Europe. The initial Cladocera development comprises the richest and oldest late Vistulian Cladocera record in Europe. These cladoceran assemblages show that a deep, oligotrophic, moderately cold-water lake was present at the beginning. It appears that the cladoceran development was mainly due to climate change, but also to changes in locally prevailing conditions in the water body. The high frequency of cladocerans, as well as the presence of cladoceran taxa preferring warmer water, was noted before approximately 16 ka BP. The biota suggests that the Oldest Dryas cooling was not severe and fairly variable in terms of humidity and temperature. The changes in Cladocera composition give evidence of what is described as the Intra-Bølling Cold Oscillation. It is also concluded that the Bølling is represented by two phases in the ?abieniec lake sediments.  相似文献

The aim of the paper is to provide an overview of the development of Czech innovation policy which started to get its shape in the first years of the 21st century. The article traces its origins to a number of interlinked factors—the introduction of European regional policy in the Czech Republic, the increased inflow of foreign direct investment into R&D-intensive sectors and also the devolution of power to Czech regions that were established in 2001 and gave a new, regional dimension to research and innovation policy. It pays particular attention to the process through which the regionally-based innovation policy advocated by the European Union (EU) has been translated and adapted in the context of a new EU member state. As an illustration of the efforts at the regional level to make a better use of the potential of R&D and innovation in the regional development, a case study of a regional innovation strategy of the City of Prague is analysed. The City of Prague was selected for a critical analysis of an innovation system and innovation policy due to the fact that it is a region with significant but until now not fully exploited innovation potential and, in addition, its first innovation strategy has been recently adopted. The innovation strategy is closely scrutinized and the process of its elaboration is critically examined within the European and especially national context. The authors demonstrate that there is a lot of conceptual ambiguity and confusion associated with the process of transferring the experiences of Western European regions to the Czech Republic. The authors believe that at least some of their observations and analysis of weaknesses of the process through which the regional innovation strategy (RIS) has been carried out will have relevance for other Czech regions and even for other regions in the new EU member states.  相似文献

Abstract

This essay discusses two interrelated questions about historical change: in what sense did early modern industries differ from their medieval predecessors; and which elements explain the diverging historical dynamics of European proto-industrial regions? Also considered is the issue of how and why some regions succeeded in selling their products in growing markets, while others apparently failed. This essay also assesses four aspects which have influenced regional success or failure, and which at the same time differentiated seventeenth- and eighteenth-century production and consumption from the late medieval world: the new role of the state, the world economy, rural consumption, and the challenge of fashion. It examines the main changes occurring in these fields between roughly 1650 and 1800, distinguishing between different phases of development for different regions and arguing that some of the success or the failure of a region, and thus their developmental capacities, lay in the interaction with these four fields. Textile industries serve as case studies, with a focus on the Southern Netherlands and comparisons from France, the Dutch Republic, Germany and England.  相似文献

This article explores how the early medieval past was used to justify Germanic political and cultural hegemony across East Central Europe during the first half of the 20th century. It highlights the ways in which medieval historians and archaeologists contributed to, and were influenced by, the program of ??Ostforschung?? (Eastern Research). A close reading of the work of two prominent German archaeologists during the interwar and National Socialist periods suggests that their conception of the early medieval eastern Alps was not only influenced by national chauvinism, but also reveals striking parallels with Western imperial ideologies typical of overseas colonial contexts.  相似文献

Administrative regions do not necessarily correspond to areas that are homogenous in terms of innovation intensity. Although this has been recognized in the literature, quantitative evidence that explicitly considers this problem is rare. Using spatial exploratory analysis on detailed regional data derived from a census of R&D performers in the Czech Republic, we identify local spatial clusters of R&D activities and assess the extent of their (mis)match with administrative borders. Overall, the results support the arguments for regionalization of innovation policy. However, the existing policy units do not appear well suited for this purpose. On one hand, there is a need for policy coordination between multiple administrative regions. On the other hand, however, there are diverse patterns within them. Similar problems are likely to haunt the regionalization process in many other countries, which is alarming, as the regional accent of innovation policies becomes ever more vehement over time.  相似文献

What Western academic literature described as ethnic or cultural Tibet in fact implies something composite and processually constructed: Tibet then often appears as a typical example for explanations of collective identity (and ethnicity). Such approaches increasingly are applied in present-day anthropology and historical studies, highlighting the historical conditions and the politically, socially and ideationally constructed features of identity. In Tibet, identity-building was strongly related to the spread of Buddhism. The new religion was introduced in the time of the Tibetan Empire (seventh to ninth century), but it was only its later spread (from the eleventh century) that led to the effective, all-embracing establishment of Buddhism in the Highlands. It was interlinked with regionally different forms of political manifestations—the founding of Buddhist kingdoms at the periphery and the emergence of monastic hegemonies in the central regions. These developments correlated with processes of conversion, which in its narrative model is described as an act of conquest, taming and civilizing the physical universe and which in theory actually never ends. Apart from considering current anthropological discussions of the phenomenon of religious conversion, this paper will include a comparative view of the history of Christianization in early medieval Europe (especially in Western Europe—the Frankish kingdom and the barbarian zones North of the Rhine and the Danube, fifth to tenth century). Inter alia this also raises questions about the initial social forces and interests promoting the new religion's adoption, and to what extent formal similarities with the Tibetan case are ascertainable in Europe.  相似文献

Vertebrate remains from two stratified sites, the Quebrada Jaguay site (QJ-280) and the Ring Site, reveal details about economic strategies practiced between 13,145 and 7500 cal yr BP on the southern coast of Perú. The near absence of terrestrial resources, a broad continuity in economic activities focused on marine resources, and flexibility within the overall strategy, are among the most interesting aspects of these data. Although they reflect economic and social decisions driven, in part, by fluctuations in environmental conditions, they demonstrate that people were sophisticated strategists actively responding to dynamic environmental conditions.  相似文献

In the context of the forceful dispute over national identity in Moldova, the Communist government of 2001–2009 aimed to articulate a project of “Moldovan identity” which was raised to the level of a state ideology. In the spirit of Soviet propaganda, this project was implemented through public holidays and celebrations. The following analysis examines two case studies—the Wine Festival and the Independence Cup—by discerning the performative practices designed as part of the nation-building project in Moldova between 2005 and 2009. Organized at the official level, but with the strong assistance of mass media, these public events were intended to win the support and attention of Moldovan society by employing rituals and performances similar to those of the Soviet period. The paper addresses the characteristics and mechanisms of these performative practices, and considers why this nation-building project did not achieve its goals, but instead caused tension and disputes. One of the main aims is to understand how the Communist government sought to redefine “the Moldovan nation”.  相似文献

High-gradient streams are localities with the most dynamic activity of geomorphological processes in medium-high mountains. This study of the frequency of floods and debris flows in a selected high-gradient stream in the Moravskoslezské Beskydy Mts was based on a dendrogeomorphic approach. It makes use of the most accurate methods applied in the dating of historic geomorphological processes. Individual events were reconstructed on the basis of the dating of various growth disturbances displayed in 99 samples taken from 56 predominantly broad-leaved trees.  相似文献

Gallerano's paper examines the reasons why Italian historians have paid little attention to the political events that followed the liberation of the Italian Mezzogiorno and the brief life of the government established under the auspices of the monarchy during the period of what was termed the Kingdom of the South. He argues that this neglect derives in part from the brevity of the period of civil government in the south, but mainly from the fact that historians have been attracted above all by the history of the Resistance which has led them to consider events in the south to be of secondary importance. Gallerano argues that such a view is quite unjustified and shows how some historians ‐ from Chabod in the early 1950s ‐ have understood that events in the south bore very directly on the broader transition from Fascism to the Republic. Challenging Renzo De Felice's recent claims that Italy's defeat on 8 September 1943 marked the beginning of a crisis of national identity, Gallerano argues that the circumstances that obtained in the months that followed made the south an exceptionally rich terrain for exploring the very contradictory feelings and expectations that were aroused in Italy by the experience of military defeat and political reconstruction.  相似文献

Compositional and structural characterisation was carried out on Early Medieval (5th–7th century) fragments of glass goblets excavated from the archaeological sites of Monte Barro, Brescia and Monselice (northern Italy) with the aim of identifying raw materials, glass-working techniques, and surface weathering characteristics. Optical analyses and X-ray spectrometry were used for bulk, and X-ray photoelectron spectroscopy and scanning and transmission electron microscopy for surfaces. The samples of each area were produced using siliceous–lime sands, with natron as flux. The differences observed in chemical composition allow to subdivide the samples from Monte Barro and Brescia from those of Monselice, the latter generally show higher silicon, calcium and aluminium and lower sodium contents than the others. By plotting reduced base glass compositions in soda–lime silica phase diagrams, melting temperatures varying from 900 °C for Monte Barro and Brescia samples to 1000 °C and more for those from Monselice were estimated. Differing Fe2O3, Sb2O5and MnO2contents are related to the different colours of the samples, Monselice samples being blue–green and Monte Barro and Brescia samples green and yellow–green. The chemical differences may be interpreted as related to different provenance and/or glass-working techniques. Surfaces are depleted in alkaline and alkaline-earth elements due to weathering process. Alteration lamellae show a nanostructure, similar to that of opal.  相似文献

The research was conducted in selected 80- to 110-year-old spruce stands in the south-eastern part of the Českomoravská Upland at altitudes from 350 m a.s.l. to 465 m a.s.l. The regional standard tree-ring chronology shows very low increments for years 1974, 1976 and 1992. After 1992, there is a sharp rise in increments with a climax in 1997. Afterwards, increments gradually decrease, reaching minima in 2003 and 2008. The years with low increments were also confirmed by the analysis of negative pointer years when over 80% of the analysed trees responded by a sharp decrease in increment, mainly in years 1976 and 1992. We can usually find values of monthly precipitation or monthly temperature average which can explain or help explain these falls in the radial growth. The correlations of diameter increments with average monthly precipitation gain only positive statistically significant values, namely for the months of May, June, July and August of the particular year. The correlations of diameter increments with average monthly temperatures gain only negative statistically significant values, namely for the months of June, July and September of the previous year and January and August of the particular year. In the examined area there is a significant negative correlation between average temperatures and monthly precipitation in July, August and September. The results of the habitual diagnostics show that with respect to the climatic conditions the health condition of the monitored stands is relatively good. On average, the defoliation does not exceed the values ascertained in different territories of the Czech Republic.  相似文献

Dietary behavior in the context of the formation of state structure, Christianization, and significant urbanization was studied, using the Great Moravian Empire (ninth–tenth century AD, Czech Republic) as a representative example. We also analyzed the impact of the disruption of social structure at the beginning of the tenth century and subsequent recovery of society during the eleventh century. Carbon and nitrogen isotopic values were measured in 189 adults (both sexes) and 74 animals representing different socioeconomic contexts (power centers/hinterlands) and chronology (Great Moravian/Late Hillfort period). Statistically significant differences in animal protein consumption were observed between centers and hinterlands. For centers, significant relationship was found between nitrogen isotopic values and socioeconomic status in males but not for females. Diachronic diet changes were observed, with the eleventh century diet characterized by higher millet consumption in both sexes and lower consumption of animal protein in males. These results confirm that Great Moravia represented a highly stratified society socioeconomically. Social status appears to determine the consumption of animal protein much more in males than in females. The diet of females also proved to be more uniform in the diachronic frame. The diachronic change in dietary behavior suggests that through the apparent recovery in the eleventh century, Moravian society did not reach its original level of welfare at least in terms of the quality of diet.  相似文献

Archaeological finds of a ritual character from Hostivice–Litovice are classed as Eneolithic cattle burials (depositions). One pit from the Funnel Beaker Period (Baalberge group; ca. 3800–3500 BC) contained a subadult bovine skeleton, whose skull bore loose horns (scurs) while still alive. This type of horn, which is movable or possibly hanging, is known from recent breeds and is caused by a special combination of alleles on two locuses and its phenotypic expression is sexually specific. However, this can also be simply a pathological state (teratology, atrophy, dysplasia or fractures), possibly caused by deliberate deformative manipulation on the horns. Such manipulations are known from recent breeding as well as from the prehistory. Both possible causations of this unique find from Hostivice–Litovice and related finds of hornlessness are discussed.  相似文献
