This paper describes the administration procedures of the European Regional Development Fund (ERDF) for Objective 2 in Catalonia. The paper shows also that the flow of an average of 100 million ECU per year from this Fund from 1989–1993, despite having a relatively slight impact on the Catalan GDP, has contributed to solving some of the bottlenecks in the Catalan economy.  相似文献

This article presents a Bayesian method based on spatial filtering to estimate hedonic models for dwelling prices with geographically varying coefficients. A Bayesian Adaptive Sampling algorithm for variable selection is used, which makes it possible to select the most appropriate filters for each hedonic coefficient. This approach explores the model space more systematically and takes into account the uncertainty associated with model estimation and selection processes. The methodology is illustrated with an application for the real estate market in the Spanish city of Zaragoza and with simulated data. In addition, an exhaustive comparison study with a set of alternatives strategies used in the literature is carried out. Our results show that the proposed Bayesian procedures are competitive in terms of prediction; more accurate results are obtained in the estimation of the regression coefficients of the model, and the multicollinearity problems associated with the estimation of the regression coefficients are solved.  相似文献

The period comprising the end of the Early Neolithic and the Middle Neolithic, dated broadly within the fifth millennium cal BC, corresponds to an interval that remains largely unknown in the extreme north-western tip of Africa. This situation contrasts with that of the Early Neolithic, a period characterised by the earliest evidence of the diffusion of a productive economy, cultivated plants and domestic animals. The paucity of data for these later phases can be explained in part by the lack of secure contexts and sequences based on radiocarbon datings of short-lived samples. The current study presents the results of the excavations of El-Khil Caves B and C that yield materials allowing re-evaluation of the chronology of a type of ceramic known as Ashakar ware. The study also identifies two traditions in the northern Moroccan Middle Neolithic. The first is heir to the so-called Impressa Mediterranean ware and rooted in the Cardial Neolithic, while the second is characterised by roulette cord impressions, red slip and tunnel lugs and probably rooted in the region of the Sahara, and has no technological precedents in the study area.  相似文献

Tourism is often understood and experienced as an exclusive activity. In supporting the concept of inclusive tourism, this volume seeks to counter that tendency by seeking out ways in which those who are typically marginalized by, or excluded from tourism can be brought into the industry in ways that directly benefit them, or that they can gain more control over tourism. This introduction to the special issue first presents a conceptual article that defines the concept of inclusive tourism and discusses seven different elements, which may constitute lines of inquiry in investigations of tourism's inclusiveness. It then presents five empirical articles that illustrate some of the ways in which an inclusive tourism approach might inform discussion of the potentials and limitations for tourism to generate wider social and economic benefits. The examples provided are from a wide range of geographical contexts, from Cambodia to Australia, Sweden, Turkey and Spain. Inclusive tourism is offered here as both an analytical concept and an aspirational ideal. We do not ever envisage minimum standards for inclusive tourism. We rather hope that there will be a restless quest to find ways to include new actors and new places in tourism on terms that are equitable and sustainable.  相似文献

Microscopy, mass spectrometry and X-ray diffraction methods were used to analyse 415 samples of natural and archaeological flint from Sierra de Atapuerca (Burgos, Spain) in order to define the different types from Neogene and Cretaceous formations in the study area, infer their genetic context and ascertain the supply sources used by hunter-gatherers who exploited this area in the Upper Pleistocene. A statistical classification model was also designed using linear discriminatory analysis and support vector machines which permitted the differentiation of the flint on an age basis.  相似文献

This article is an interpretation of historical narratives written by nineteenth–century German and French historians (among them Johann Gustav Droysen and Jules Michelet) about the French Revolution and the biographies of notable queens. Central to this historical narrative are Marie–Antoinette of France, Louise, queen of Prussia, and Elizabeth, empress of Austria. The text is concerned with the process of transforming the executed queen of ancien régime France into the image of the nineteenth–century bourgeois ideal of women and monarchy. Thus the essay is also about the creation of myths and about male bourgeois and middle–class fantasies.  相似文献
