Venice lagoon formed part of a network of inland waterways used for navigation in the northern Adriatic, an almost continuous system of lakes, river‐mouths and canals, at least partly pre‐Roman in origin. The fossae which cross the present lagoon are the continuation of a complex system of natural watercourses and artificial canals between Ravenna and Aquileia. Two Roman buildings discovered on the present San Felice canal could be interpreted as providing navigational assistance at points linking the sea and inland routes. © 2009 The Authors  相似文献

Two concentrations of animal bones, almost exclusively from small mammals and wild birds, were found within the destruction debris of a Roman bath complex in Sagalassos (SW Turkey). The overall species spectrum, skeletal element representation, fragmentation and preservation condition of the bones indicate that they represent the prey remains of a large nocturnal avian predator, more precisely the eagle owl (Bubo bubo). Differences in skeletal element representation and in prey species' spectrum show that the two bone clusters derive from pellets deposited near a nest site and a roost site, respectively. Radiocarbon dates obtained from the bones indicate that eagle owls lived in the collapsing bath complex during the second half of the 6th to the beginning of the 7th century AD, before the final abandonment of the town. The MNI of the prey animals found at the nest site, confronted with the daily dietary needs of a female eagle owl and its young, indicates repetitive use of the same place during several years.

Urban growth drivers in a Europe of sticky people and implicit boundaries   总被引:2,自引:0,他引:2  
We investigate urban GDP per capita growth across the EU12 usingdata for functionally defined cities—rather than administrativeregions. We test hypotheses on the role of human capital, EUintegration and fragmentation of urban government and explorespatial dependence and mechanisms of spatial interaction. Resultsare acceptable on standard econometric tests without measuresof spatial interaction but there is spatial dependence. If variablesreflecting spatial adjustment are included, they are statisticallysignificant and eliminate spatial dependence. Not only do theresults now provide consistent estimates of parameters, butthey also support relevant theoretical insights and show nationalborders are still significant barriers to economic adjustment.People in Europe are sticky so it is unreasonable to assumespatial disparities will disappear. Our findings also implythat cities in Europe form national rather than a single continentalsystem.  相似文献

From 1643, the catholic quarrel on grace sees the clash of three theological parties, that of the Jesuits, won oven to molinism, that of the dominicans, defenders of thomism, and that of the jansenists, partisans of a return to strict augustinism but equally concerned with defending themselves from accusations of heresy by putting forward their conformity with thomism. The present article attempts to follow the evolution of the different currents in the time of the crisis of 1655–1657 by utilizing the contemporary texts of Blaise Pascal as an observatory and by showing how the jansenists gradually liquidated the middle solution of a molinizing thomism.  相似文献

Pitch compounds are frequently identified inside archaeological ceramic vessels. As their presence might affect the permeation of oil or wine into the ceramic fabric, experiments were conducted in which the diffusion of lipids or polyphenols into pitched and non-pitched modern vessels was followed by chemical analysis. Results show that the polyphenols of wine can intrude into the ceramics even through a pitch layer. Consequently, the absence of polyphenols in archaeological sherds is not due to their inability to reach the ceramic matrix under the pitch layer. By contrast, a pitch layer is quite effective to avoid oil intrusion into the ceramic matrix. Thus, it seems logical that oil amphorae would have been coated with pitch at the inside prior to use. Experiments in which the pitched ceramic was simultaneously exposed to oil and wine, show that the wine makes the pitch more permeable for the lipid compounds. These experimental data are confronted with residue analysis results obtained on amphorae fragments excavated in Sagalassos, Turkey. Pitch and oil were frequently found together. Based on a polyphenol test, indications for wine storage could only be obtained for two vessels. Against this background, the possible uses of the Sagalassos amphorae are discussed, and the traditional association of pine pitch with wine storage in archaeological amphorae is critically assessed.  相似文献

Nowadays, cities formulate long-term strategies to address the challenges and opportunities they face. Numerous strategic plans or planning instruments are developed for this purpose. In this article, we would like to examine the role, impact and relevance of these types of plans in decision-making processes concerning urban development projects (UDPs) in the Flemish Region of Belgium. To what extent do strategic plans succeed in capturing and steering the complexity of spatial interventions in contemporary urban contexts? We argue that a complexity-acknowledging perspective provides a more realistic and adequate view here by seeing strategic plans as only one among many elements in the set of tangled inter- and intrastrategic processes which together determine UDPs. A comparative and qualitative case study was carried out in the city of Kortrijk. The decision-making of three UDPs was studied thoroughly. Interviewing key actors and analysing policy documents helped us to (re)construct the complex decision-making processes and to stipulate the meaning of all involved formal plans and planning tools.  相似文献

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, 14C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.  相似文献

The mastication of tough and hard foods combined with the extensive use of teeth as tools, have been considered possible antemortem causes in determining enamel microfractures of the tooth crown. This phenomenon, known as dental chipping, has been found in different fossil hominins and in several pre-historic and historic human populations who adopted different subsistence strategies. However, little is understood of the mechanism, function and the formation of dental chipping.  相似文献
