Recent contributions provide researchers with a useful toolbox to estimate counterfactual distributions of scalar random variables. These techniques have been widely applied in the literature. Typically, the dependent variable of interest has been a scalar and little consideration has been given to spatial factors. In this paper we propose a simple method to construct the counterfactual distribution of the location of a variable across space. We apply the spatial counterfactual technique to assess how much changes in individual characteristics of Hispanics in the Washington DC area account for changes in the distribution of their residential location choices. 相似文献

This is an overview of the range of gardens, garden plants and garden work in early medieval Spain and Portugal, and of the kinds of relevant source material available. There were different kinds of garden, from the architectural gardens of Andalusī rulers and officials to peasant plots in the countryside. Fine gardens were closely associated with an elite and were southern rather than northern. Productive gardens could be found all over the peninsula; vegetables were clearly grown in them, with the emphasis on pulses, but they constituted a small proportion of produce. Fruits were exceptionally important as a source of vitamins, sugar and mineral salts. 相似文献

In her recent book, Virtus Romana, Catalina Balmaceda provides a fascinating analysis of the concept of virtus in Roman historiography. Although virtus, which translates as courage or more generally as virtue, meant different things to different Roman historians, Balmaceda shows that disagreement was never about whether historians should provide readers with examples of virtue. Historians' differences of opinion focused rather on where such models were to be found and what they should look like. This review essay summarizes Balmaceda's main arguments, raises a question about historians' own virtus, and draws some implications from the book for the study of scholarly personae. Did the persona of the historian as a public moralist, such as is known from nineteenth‐century Europe, originate in ancient Rome? 相似文献

This study explores the feasibility of using strontium isotope (87Sr/86Sr) analyses of enamel from domestic dogs (Canis familiaris) to investigate networks of exchange in the prehistoric Circum‐Caribbean. Dog teeth were obtained from burial and domestic contexts from two prehistoric sites (Anse à la Gourde and Morel) on Grande‐Terre, Guadeloupe (Lesser Antilles). Strontium isotope results were compared with local biosphere 87Sr/86Sr data at the scale of the site, island and archipelago. The isotope results indicate both local and nonlocal origins with three dogs (30%) identified as nonlocal (one from Anse à la Gourde and two from Morel). The variance in 87Sr/86Sr ratios of the nonlocal dog teeth is consistent with diverse multiple origins external to the island of Grande‐Terre but consistent with origins from other islands of the Lesser Antilles. The diverse origins of the nonlocal dog samples indicate that the prehistoric circulation of dogs occurred at multiple scales from regional to long distance. Significantly, the 87Sr/86Sr ratios of some of the dog teeth are comparable with values of nonlocal humans at Anse à la Gourde determined in previous studies. It is possible that these comparable 87Sr/86Sr ratios result from similar natal origins, for example if individuals were migrating to Guadeloupe with dogs. The results of this study contribute to an ongoing regional investigation of the economic, social and political roles of animals and animal remains and the multiscalar networks of prehistoric mobility and exchange in the Circum‐Caribbean region.
