This paper studies the relevance and nature of shifts in relative prices at the regional level in Spain. Deviations in relative prices tend to be small (at most half a point of inflation annually) but persistent. They are determined by features intrinsic to deep economic integration, in particular, wage mechanisms operating at the national level. This is in stark contrast to evidence at the international level. Therefore, while acknowledging that divergent price evolutions are possible in the European Monetary Union, their nature will be different from those observed among Spanish regions. 相似文献

This paper studies the relation between coalition structures in policy processes and policy change. While different factors such as policy images, learning processes, external events, or venue shopping are important to explain policy change, coalition structures within policy processes are often neglected. However, policy change happens as a result of negotiations and coordination among coalitions within policy processes. The paper analyzes how conflict, collaboration, and power relations among coalitions of actors influence policy change in an institutional context of a consensus democracy. Empirically, I rely on a Qualitative Comparative Analysis to conduct a cross‐sector comparison of the 11 most important policy processes in Switzerland between 2001 and 2006. Coalition structures with low conflict and strong collaboration among coalitions as well as structures with dominant coalitions and weak collaboration both facilitate major policy change. Competing coalitions that are separated by strong conflict but still collaborate strongly produce policy outputs that are close to the status quo. 相似文献

Vultures are ubiquitous taphonomic agents in most biomes. However, taphonomic studies of vultures are scarce and very little
is known of the damage they cause to bone surfaces when consuming carcasses. This study presents the results of a taphonomic
analysis of bones modified by griffon vultures. Although some marks created by these agents are diagnostically unique, others
are extremely similar to modifications caused by other biostratinomic processes. This renders interpretations of marks on
bones very problematic when these modifications are considered in isolation rather than at the assemblage and contextual levels. 相似文献

Identifying tools by means of morphological attributes are widely used in lithic studies to categorize retouched artifacts from different archaeological periods. This procedure has facilitated the exchange of information between separate researchers and has improved the comparison of different assemblages. In these classifications, denticulates and notched tools have been regularly interpreted as analogues and chronologically unvaried in different and vast territories. Based on the definitions developed by Bordes, the denticulate category has become a catchall for any kind of tool bearing concavities. In this paper a new quantitative approach to the classification of denticulates and notched tools is proposed. The new methodology is based on measuring the length of notches and their distribution on the perimeter of the blank. Analyzing the lithic series of the Abric Romaní rock-shelter (Spain) and Grotta Maggiore di San Bernardino (Italy) led to the identification of 11 redundant forms: eight denticulates and three notched tools. Moreover, the application of Kuhn’s Geometric Index of Unifacial Reduction brought local manufacturing trends to light, calling into question the presumed geographical uniformity of these categories of artifacts. 相似文献

Abstract: Tracing the commodity chain of broccoli from Nashville, Tennessee supermarkets to Maya farmers in highland Guatemala, this paper examines relations of desire and political economic power. We argue that the global broccoli trade is shot through with desires—desires of Western consumers to eat healthy foods as well as desires for Maya farmers to get ahead economically. Such desires simultaneously subvert and sustain the hegemonic constellations that anchor crucial nodes in the international broccoli trade. 相似文献

As deportations from the United States rose to unprecedented levels, a nationwide immigration enforcement program Secure Communities helped identify deportable noncitizens under arrest in county jails. Examining county‐level variation in deportation activity between 2008 and 2013, this paper contributes to immigration policy research by examining how county officials in some locations facilitated exceptionally restrictive deportation outcomes while others exercised the discretion to turn noncitizens over for deportation sparingly. Consistent with a hypothesized “tiered influence” relationship, but contrary to a “racial threat” hypothesis, Hispanic concentration predicts the highest levels of exercised discretion where Hispanic concentration is neither too small nor too large. Noncitizens under arrest seem to have benefited from above‐average Hispanic concentrations, except in counties where Hispanics exceed about 40 percent of the population. 相似文献

This article discusses the application of new technologies, software coding and computer analysis in the social sciences and humanities, mainly in the field of economic history. In the last two decades, the use of new computer technologies among historians to develop theories and solve questions has fostered a vibrant historiographical debate. However, these new digital tools have largely been used as an end in themselves, rather than as a means to develop hypotheses and answer questions. This has prevented researchers from fully exploiting such technologies in their field. In this article, I discuss how I designed a new multi-relational database using the “Access” package and SQL language to test the “industrious revolution” hypothesis and present the “vicarious consumption” theory as an alternative model for analyzing the eighteenth-century circulation of Chinese goods in the Western Mediterranean region. It presents the cross-referencing method I used to analyze the historical information I collected, mainly from probate inventories and trade records. This method makes it possible to navigate through the data in a way that goes beyond the traditional use of “excel” tables. 相似文献
