Well-preserved bomb craters in the forests of central Normandy, NW France, constitute archaeological legacies of combat inland from the D-Day beachheads that greatly extend the inventory of Second World War conflict landscapes in northwest Europe. Field survey and analysis of German and Allied documents demonstrates that bombscapes in the Forêt domaniale des Andaines and Forêt domaniale d'Ecouves reflect US Ninth Army Air Force attacks on a German fuel depot and radar installation, respectively, during June-August, 1944. One hundred and thirty-six craters are mapped, described and linked to specific air raids, bomb types and, for one raid on the 13th June, six specific participating aircraft and aircrews. These landscapes echo the impact of widespread tactical bombing against targets close to civilian population centers, and in some cases employing civilian and PoW labor. They are therefore well-placed to contribute to wider heritage narratives around the non-combatant experience of aerial warfare in WWII. 相似文献
If the overall expansion of the farming system was determined by the Neolithic Demographic Transition (NDT), i.e. by demographic pressure, what determined the rate of expansion? What is the link between the rate of expansion, the farming system and demographic density? In a first approach, the issue of the different rates of expansion of the farming system on the map is addressed in terms of 21 geo-ecological, climatic and cultural factors and forager populations, via an ordinary least square regression technique (OLS). In a second approach, the variability of the rate of expansion is analyzed in terms of specific patterns identified for the ceramic culture areas, via a cluster analysis. The expansion rate is negatively correlated with the intensification of the agricultural system, as well as with demographic density. Expansion is slow in ecosystems with an intensive farming system with relatively high demographic density, and vice-versa. 相似文献

The growing interest in causal inference in recent years has led to new causal inference methodologies and their applications across disciplines and research domains. Yet, studies on spatial causal inference are still rare. Causal inference on spatial processes is faced with additional challenges, such as spatial dependency, spatial heterogeneity, and spatial effects. These challenges can lead to spurious results and subsequently, incorrect interpretations of the outcomes of causal analyses. Recognizing the growing importance of causal inference in the spatial domain, we conduct a systematic literature review on spatial causal inference based on a formal concept mapping. To identify how to assess and control for the adverse effects of spatial influences, we assess publications relevant to spatial causal inference based on criteria relating to application discipline, methods used, and techniques applied for managing issues related to spatial processes. We thus present a snapshot of state of the art in spatial causal inference and identify methodological gaps, weaknesses and challenges of current spatial inference studies, along with opportunities for future research. 相似文献
This paper examines cooperation patterns of firms in the German low-technology region of Lower Bavaria. Particular emphasis is placed on the interplay among the spatial scale of cooperation, the form of cooperation and the type of innovation. Generic results show that overall, firms with a spatially more diverse set of cooperation linkages have a higher likelihood of innovating. However, the innovation outcomes differ depending on the spatial scale of cooperation. While cooperation with regional partners positively correlates with low-threshold innovations, cooperation with spatially distant partners positively correlates with product innovations. Surprisingly, it is application-oriented cooperation that channels the relation in both cases. The findings support the view that innovation of firms in low-technology regions is driven by ‘development’ rather than ‘research’. It also suggests that innovation-driven growth may even be possible in regions with limited values on the traditional innovation-supporting factors. 相似文献
ABSTRACT All previous theory and research have led to the expectation that the density of service establishments will be proportional to the 2/3 power of the density of the population served by them. Study of the distribution of over 400 nongovernmental establishments refutes this expectation for such cases. A previous derivation from time minimization theory is reformulated to encompass these new findings. 相似文献
