The aim of this paper is to extend the range of current analytical procedures that archaeologists use to understand movement. In particular, how a landscape becomes ordered by simply defining a destination. More specifically, this study proposes the derivation of a focal mobility network, i.e. the network of most likely paths towards a given destination, and explores several of its applications within a landscape archaeology framework. The suggested extensions are based on existing standard procedures within most GIS. A series of synthetic control surfaces and an archaeological study focused around Iron Age hillforts in Galicia (NW Spain) are used as case studies to illustrate different analytical possibilities. 相似文献

When in 1945 the Czechoslovak authorities confiscated the estate of the Princes von und zu Liechtenstein, the two countries became involved in a dispute which had not been resolved until recently, at least on a diplomatic level. For several decades, the 1948 Communist coup d'état in Czechoslovakia dashed the hopes of the Liechtenstein family for a restitution of their confiscated assets. However, officials responsible internally admitted that the property confiscation had been questionable in the case of the Liechtenstein family. The court had not confirmed the confiscation until after the Communist coup. However, the Liechtenstein family did not renounce their claims, and after the collapse of the Communist regime in 1989 they brought them up again. 相似文献

Barnacles of the species Pollicipes pollicipes are crustaceans that nowadays live on wave-beaten rocky substrates in the intertidal and low-shore zones on the coasts of Atlantic Europe and North Africa. At the present time, the exploitation of this species is profitable, especially in northern Spain where this sea-food is highly valued, as well as expensive. However, the gathering of this resource, which is carried out manually by the percebeiros or “goose barnacle fishers” entails great risks. 相似文献

This article addresses the role of geographical proximity for knowledge and innovation collaboration patterns in the Czech Republic and assesses the factors which determine the spatial distribution of innovation co-operation. The article uses alternative sources of empirical data to map collaboration patterns of innovating companies, research institutes and universities and to find basic regularities. By this, the article aims to fill in the gap in current research focused rather on most advanced regions by adding new knowledge from a transformation, post-communist economy. Also, it aims to shed light on the issue of the role of proximity between actors involved in collaboration in the sphere of knowledge and innovation creation which still remains rather elusive. The findings indicate that even though co-location and intra-regional knowledge and innovation collaboration exist, it cannot be regarded as a decisive characteristic. Geographical proximity is not a crucial condition in knowledge and innovation collaboration as all actors are involved to an important degree in international linkages. Yet, the role of the specific institutional context and factors at micro-level influence the innovation co-operation pattern. 相似文献

In East-Central Europe (ECE), the evolution of feminist geographies began after the end of state socialism. Aiming to identify individual and shared characteristics, this study outlines the development of gender/feminist geography in East-Central European countries. Providing a brief historical overview, the first part of the article substantiates the arguments that i) the evolution of feminist geography in ECE is linked to the post-socialist transition; although the fall of state socialism has removed the political, social and ideological obstacles that prevented its gaining ground, this approach is still considered to be relatively new; and ii) today, development is hindered mainly by conservative mainstream geography, which seems slower in transforming itself than in some related disciplines which have ‘embraced’ gender studies. The topics, methods and theories of feminist geography that have developed in ECE is significantly influenced by the resistance that advocates of feminist geography have to contend with from representatives of mainstream post-socialist geographies. The second part of the article presents the major characteristics of gender/feminist geography in Europe's post-socialist region, while providing an outline of the various methods used in an attempt to earn positive recognition for gender studies. The concluding section maps some lessons to be learnt on the relationship between the production of feminist geographical knowledge and post-socialism. 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

Aspects of 2nd- to 5th-century ce Roman production technology and knowledge transfer in southern Austria (known as Noricum) were examined. With no evidence for workshops identified in the study area, 44 grey ware bowls from two sites at Aguntum and Lavant were studied macroscopically, and combined with optical microscopy, X-ray powder diffraction, prompt gamma activation, neutron activation and scanning electron microscopy, in order to understand whether one (large) workshop supplied these bowls, or whether the bowls were produced by several (small) workshops nearby. Combined with information from the geological background, the results were used to tentatively indicate the production location. The results indicate that the grey ware bowls from Aguntum and Lavant were produced by local workshops nearby. The bowls were manufactured with similar clay sources, tempered with crushed calcite-marble rocks from the Tauern Window, their surface smoothed and burnished, and fired between 800 and 850°C in a reducing atmosphere of an open fire. This is taken to suggest that Roman potters, who were located at Aguntum and Lavant, shared strategies of raw materials selection, paste preparation, finishing and firing, and transferred technological knowledge through time. 相似文献
