The recent re‐analysis of the Maglemosian faunal assemblages from Mullerup and Lundby Mose (Sjælland) has led to the discovery of new hunting injuries in the Danish Early Mesolithic. In total, including the two cases already published, two examples come from the Lundby Mose site, and seven from Mullerup, including embedded flint fragments and perforations. Such new data emphasise the need for meticulous re‐analysis of bone assemblages, relying on experimental work on projectile impacts, in order to increase the number of such discoveries. The link with weapons and hunting techniques and the question of the frequency of projectile impacts during the Danish Mesolithic are discussed, as well as their significance in terms of mobility of human groups, particularly in the case of healed wounds.

This study aims to reconstruct the Holocene fluvial history of the Tremithos river, south central Cyprus and examine linkages to regional and local archaeological records. Three stratigraphic profiles (Sp1, Sp2 and Sp3) located in the lower valley have been investigated using sedimentology and magnetic parameters. The 14C dating of 10 samples reveals mid-Holocene ages for Sp1 and Sp2, while the upper most part of Sp3 can be attributed to the early to mid-Holocene. Two main phases of vertical accretion have been recognised: the first, recorded in the lower most part of Sp3, could not be dated but might relate to the late Glacial period. It is not associated with any archaeological artefacts. The second, recorded in all profiles, dating from ca. 5000 to ca. cal 2800 BC, spans the Late Neolithic Sotira (cal 4800/4000 BC) and Late Chalcolithic (cal 2900–2500 BC) cultures. The sediments of Sp1 and Sp2 are up to 8–10 m thick and mainly composed of fine material. However, an intercalated phase of coarse sediment has been identified at the beginning of the third millennium BC, indicating a sudden change in river dynamics, potentially associated with the 5.2 ka rapid climate change regional event. Typical mid-Chalcolithic (ca. cal 3300–3050 BC) ceramics found in a palaeosol in Sp2 indicate for the first time human occupation of the Tremithos river terraces. Two other palaeosols have also been recognised in Sp3 and radiocarbon dated to ca. cal 5600–4100 BC and ca. cal 2900–2600 BC, respectively. These results make it possible to propose a palaeogeographic reconstruction of the Holocene evolution in the Tremithos valley and to make a preliminary assessment of the relative roles of tectonics, climate and anthropogenic forcing. 相似文献

This article has been written in response to Pigozzi and Bagchi-Sen's (1995) work on the impact which affiliates of foreign manufacturing firms make upon employment in the US economy. It will be argued that their analysis is incomplete because of inadequacies in their conceptual framework. In order to assess the impact of multinational subsidiaries it is necessary to use a framework which includes a more extensive range of modes of entry and subsidiary types. It is also necessary to consider, more extensively, the indirect employment effects brought about by the linkages which are created by the foreign-owned subsidiary as well as the dynamic effects which influence the competitive environment including the capabilities of indigenous firms. 相似文献

High-Impact Educational Practices (HEPs) are a set of specific teaching and learning approaches proven effective in university education. This paper focuses on the benefits derived from utilizing three particular HEPs (inquiry-based collaborative activities, undergraduate research, and experiential learning) while teaching a snow and ice field course titled “Silverton Field Experience.” Student evaluations and instructor feedback reinforce the notion that HEPs encourage deep learning. Deep learning is manifest through increased enthusiasm and participation as well as learning in ways that are meaningful, creative, and stimulating. In terms of pedagogy in geography, these HEPs also create an expanded sense of place and a new way to encourage spatial thinking. The HEPs outlined here are replicable in different geography sub-disciplines and among different settings in higher education and prove exciting to an audience of pedagogic researchers and teacher-practitioners in geographical education. 相似文献

China’s new Eurasian ambitions: the environmental risks of the Silk Road Economic Belt 总被引：3，自引：0，他引：3

China is moving ahead with the Silk Road Economic Belt, an ambitious infrastructure development agenda with the distinct promise of regional and sub-regional economic development. However, the initiative will create new environmental risks across the entire Eurasian continent, especially in countries with predominately poor records of environmental governance, including the former Soviet republics and Russia. Concurrently, on the domestic front, the Chinese Government has launched a new policy paradigm, “ecological civilization,” to dramatically improve environmental regulations, reduce pollution, and transform industries by adopting new green technologies and higher environmental standards. But does China’s intention to go through a “green shift” domestically resonate with these new transborder infrastructure development mega-projects? This paper will attempt to answer this question by juxtaposing China’s new domestic policy paradigm with environmental standards currently proposed in its global outreach projects focusing on China-northern Eurasia and China-Russia, including trade exchanges in natural resources. 相似文献

This contribution deals with the observation and evaluation of the issues of local economic development with a focus on the relatively new method of the local multiplier LM3. The main objective of this article is to evaluate the application possibilities of selected tools for the analysis of local economic development, in order to verify the effectiveness of the methodology of the local multiplier LM3 and to discuss the possibilities of its practical use. This LM3 method is perceived to be one of the convenient methods on how to capture certain components of local economic development. This indicator of the power of local economies is verified within field research in two case studies conducted in the ?umava region in Southwest Bohemia. The added value of this contribution is both methodological and practical. Currently, there exist only very few studies using the LM3 method in the Czech Republic and they do not offer satisfying evaluation of possible broader use of this method in the area of local development in the specific Czech regions. Having summarized two new case studies, this article contributes to the methodological discussion of the LM method and includes concrete practical recommendations for future research and also practical use. 相似文献

Urban social change and large-scale demolitions in the name of urban renewal often give rise to social conflicts. In this study, we investigate how resistances to this change emerge, coalesce and revolve, and how they use heritage to generate cumulative impact. The analyses of urban change and resistance in Gårda, a working-class neighbourhood of Gothenburg, Sweden, showed social conflicts to be instigated by their stigmatisation. Since the 1970s, Gårda has been called ‘out of place’ and marked for demolition. These demolitions were given legitimacy by the ‘housing quality standards’ that emerged in the 1930s as a means to reduce social inequalities. Over time these standards became an ‘intangible heritage’ employed in neoliberal urban policies. In response, five ‘Re-Gårda’ resistance strategies emerged to contest Gårda’s future. Resistance groups uncovered new values for Gårda, curating the vision with the slogan ‘have a coffee in Gårda’, and structuring the narrative ‘upgrade Gårda’. This challenged the dominant discourse ‘demolish’ or ‘conserve’ Gårda, and resulted in a government decision to protect Gårda as a ‘heritage site’. Investigating heritage and resistance in Gårda helped us reveal the potential of resistance in challenging the limits of authorised urban and heritage discourses, and in realising socially equal and just cities. 相似文献

History shows that wars can be enormously disruptive of economic activity, especially international trade, national income, and global economic welfare. This article analyzes the impact on the European regions the Russian invasion of Ukraine using the largest and most updated multiregional input-output model for Europe. Two shocks, trade and inflation, and four alternative scenarios are simulated. The scenarios are considered regarding the number of countries applying a trade embargo, the exemption of oil and gas, and the potential trade diversions with third countries such as China. We obtained a significant fall in GDP (−1.7%), 3.7 m lost jobs and 3% raise over the prewar inflation rate. For trade shock, large indirect effects are obtained, indicating the high relevance of the sectors and countries exposed to the war and the sanctions. The republics of the former Soviet Union, as well as the satellite countries of the former communism, face the harshest adverse impacts. This work shows the importance of breaking Russia's colonial economic ties to the countries in Eastern Europe. 相似文献

Multiple sequences of radiocarbon dates extracted from organic materials are increasingly being used to provide robust chronologies for landscape development, particularly the timing and correlation of significant climatic and ‘process’ events. Whilst the validity of using such frameworks in sedimentary environments such as lake basins and raised bogs has been the focus of much attention, such debates have not extended to fluvial systems. Using examples from three lowland, vertically accreting river valleys in East Anglia, UK, this paper assesses the robustness of their associated radiocarbon chronologies by assessing the contrasting age estimates that are obtained by dating different parts of the same organic sample (humic, humin and plant macrofossils) at a variety of stratigraphic levels. Overall, the humin and humic acid fraction results were statistically consistent, whilst the plant macrofossil remains were found to be of a slightly younger age. In these examples, it is argued that the younger ages appear to be the result of Phragmites (common reed) roots pushing plant macrossils through the sedimentary sequence or opening up voids for material to fall through, although studies in lacustrine and mire environments suggest alternative explanations may also be possible. Whichever explanation is preferred, this study demonstrates clearly that the complexity of valley floor stratigraphy and processes is such, that using single radiocarbon dates, whether AMS or bulk samples to reconstruct chronologies of ‘geomorphic system response’ may need to be refined and subjected to the same level of assessment that has been applied in other sedimentary systems. 相似文献
