Making use of analytical, chemical and mineralogical methods, this paper focuses on the analysis of inclusions in order to address the question of the provenance of prehistoric artefacts excavated in Gura Cheii-Râ?nov Cave (Romania). The study represents the first discovery of bitumen on lithic tools belonging to the Upper and Middle Palaeolithic in Europe. The material was identified through several analytical procedures, such as Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray fluorescence (EDXRF), inductively coupled plasma atomic emission spectroscopy (ICP-AES), and X-ray diffraction (XRD).  相似文献

ABSTRACT On a sample of U.S. urbanized areas in 2000, we test theoretical hypotheses of the effect of land‐use controls on the spatial size of urban areas. We find that minimum lot‐size zoning and maximum FAR restrictions expand the urban area, while maximum lot‐size zoning, urban growth boundaries, minimum square footage limits, maximum building permit restrictions, minimum person per room controls, and impact fees contract the urban area. All of these findings are consistent with theoretical predictions although the effect of urban growth boundaries and minimum square footage limits are not statistically significant.  相似文献

Nous commençons, ce semestre, une série d'entretiens avec des historiens qui représentent dans leurs pays des références intellectuelles incontestables mais qui sont encore peu connus des jeunes historiens étrangers. Nous voudrions réfléchir avec eux sur les méthodes qu'ils utilisent ou, comme ici avec M. Aleks Buda, sur leurs parcours parce qu'ils sont représentatifs d'un milieu scientifique national, d'un type de discours sur l'Histoire, d'une génération de savants.  相似文献

Dento‐alveolar pathologies: caries, ante mortem tooth loss, abscesses, calculus, alveolar resorption and tooth wear were analysed in two composite skeletal series from Croatia's eastern Adriatic coast (Dalmatia). The first consists of 103 skeletons from seven Late Antique (3rd–6th century AD) sites, the second of 151 skeletons from three Early Medieval (7th–11th centuries AD) sites. As recent bioarhaeological studies (Šlaus, 2008 ) showed a significant increase of disease loads and trauma frequencies in Dalmatia during the Early Medieval period, the aim of this study was to investigate whether dental health was equally adversely affected by the Late Antique/Early Medieval transition. The results of our analyses show that the frequencies of carious lesions, ante mortem tooth loss, abscesses and alveolar resorption increased significantly during the Early Medieval period, as did the degree of heavy occlusal wear on posterior teeth. These data suggest a change in alimentary habits, with a significantly higher dependence on carbohydrates and a greater reliance on hard, fibrous foods requiring vigorous mastication in the Early Medieval diet. The combination of higher calculus and lower caries rates in the Late Antique series similarly suggests more protein in the Late Antique diet and is, therefore, also consistent with the hypothesised change in alimentary habits. In general (the two exceptions are male caries and female alveolar resorption frequencies) lesion frequencies increased uniformly in both sexes suggesting that the deterioration of dental health during the Early Medieval period equally affected males and females. Cumulatively, the collected data suggest that the political, social, economic and religious changes that characterised the Late Antique/Early Medieval transition in Dalmatia resulted in a clear discontinuity, not only from the cultural, but also from the biological point of view with an evident deterioration of oral health during the Early Medieval period.

In this paper, possible functions of the gesture of indicating, either with hands or postures, or with looks or facial expressions, portrayed on the figures found in the history painting of the XVIIth century are studied. Two examples from the paintings of Le Brun and Poussin are analyzed in detail to show how these gestures are signifying elements of the story represented through the dispositio of its figures as well as operative parts of a representational apparatus historically and esthetically defined. The gesture of indicating, intended to articulate and regulate the viewer's reception of the painting, is supposed to constrain how he adheres to the religious, social or political values — that is the ideological background of the scene represented in the painting.  相似文献

This article seeks to understand why community forestry enterprises in the Mayan rainforest of Mexico are losing ground, while middlemen and manufacturers are regaining control over forestry resources. It focuses on the case of the Ejido San Felipe Oriente where an NGO codesigned a commercialization platform with the objective of bringing together local cooperatives to negotiate in the market from a position of strength. The project was hampered by an internal rupture in the ejido; in investigating this rupture, the authors use the concept of institutional bricolage to understand local power struggles, and the theory of gradual change to search for historical causal mechanisms. They find that the proximate causes of the rupture were family rivalries, suspicions of embezzlement, unfair exclusions, and the disruption of customary practices regarding the distribution of monetary benefits. However, historical continuities lay beneath the power struggle: ejidos in the Yucatan Peninsula have used their function as intermediaries to subordinate local interests rather than promote endogenous development. The authors advocate for an institutional design process that takes account of the unconscious and taken-for-granted meanings that influence institutional adaptation; they encourage development practitioners promoting community forestry enterprises in the Mayan rainforest of Mexico to address historical continuities in local institutions as a focal target of development interventions.  相似文献

In this article, we construct new, simple, and nonparametric tests for spatial independence using symbolic analysis. An important aspect is that the tests are free of a priori assumptions about the functional form of dependence, making them especially suitable in situations where the dependence is nonlinear. We define the concept of a similarity relation, which is used to keep track of similarity between neighboring observations. This similarity count is used to construct new statistical tests based on both random permutation simulations and derived asymptotic distributions. We include a Monte Carlo study to better illustrate the properties and the behavior of the new tests under several synthetically generated processes. Apart from being competitive compared with other nonparametric and parametric tests, results underline the outstanding power of the new tests for nonlinear‐dependent spatial processes.  相似文献
