In the great civilisations of the past, shapeshifting promised a restoration of order in turbulent times in return for the deference of loyal subjects. It was a strategy of the powerful to maintain advantage and could also be used to bind opponents to an undesired form. This study finds its resonance in the contemporary shapeshifting that is the supposed transition from the fossil fuel economy. With reference to the fusion of oil, grain and sugar companies in Brazil's ethanol sector, it explores how amidst economic, environmental and political insecurity these “old villains” of the carbon economy have fused and emerged as the “new heroes” of the green economy. Accounts of dissenting rural subjects, however, unveil the mythical nature of avowed social gains from this shapeshifting. Amidst rural conflict and a successive weakening of regulation, it becomes evident how their petrification, in a metaphorical and increasingly literal sense is required.  相似文献

This paper explores regional (département or NUTS3) income inequality in France between 1860 and 1954. To this end we first document the existing evidence, evaluate the estimation methods and findings, assess the suitability of each approach and address potential concerns. We then present our own subnational estimates of per-capita income, derived following Geary and Stark. Overall, we find that indirect estimation (or top-down) methods provide somewhat differing results, thereby calling into question the validity of some of these approaches. Our estimates, meanwhile, appear to fit reasonably well with direct estimations (or bottom-up) of value-added and income and provide evidence in support of a decline in regional inequality over the period of study.  相似文献

The emergence of anti-democratic movements is a central puzzle to social science. We study a novel and rich historical dataset covering Swedish municipalities during the interwar years and find a strong link between the presence of a military garrison and the emergence of fascist parties. We interpret these results as suggesting that fascist mobilization in Sweden was driven by discontent with the process of disarmament brought about by democratization. In contrast, poor economic conditions, as captured both by levels of and changes in the local poverty rate and tax base, do not explain the strong link between the fascists and military garrisons. We relate these results to influential theories of democratization.  相似文献

This work analyses the main Spanish legislative and urban planning instruments, highlighting some of the most important structural problems of the current Spanish urban realities. The survey on legislation runs from the first Land Use Act of 1956 to the decentralization of the administration and the culmination of the transfer processes to the respective Spanish regions. Later, we study the complete well-structured hierarchy of urban planning instruments in use at present. Finally, we analyse how these and other factors have an influence on the capacity to control housing prices and on a lack of sustainability characterized by the excessive urbanizing use of the land.  相似文献

This article analyses the evolution of Community expenditure, on the basis of the data given in the budget and in the EDF, from the origin of the process in 1957 until the year 2002, the last definitive figures. The technique of principal component factor analysis has been applied to these variables. The basic objective of this study is to detect the interrelationships among the policies of the Union and to effect a classification of them, in order to detect the priorities of the European project and to estimate the dimension of the impact of its policies during the period.  相似文献

The Qhapaq-Ñan Project promotes the integration of shared cultural values among six countries: Argentina, Chile, Bolivia, Peru, Ecuador and Colombia. These countries are collaborating to nominate the Main Andean Road or “Qhapaq-Ñan” for inclusion on UNESCO’s World Heritage List. Although the participants envision local and Indian communities as the true beneficiaries of the project, and the archaeological effort is already under way, communities associated with the road have not been involved. (At the very moment we are editing this article (March 2007) Argentina is holding the first meeting about a project that is already five years old, with some of the Indian communities of the territories where the project will be carried out. The participation, however, was far below what we expected.). Following the guidelines of the World Archaeological Congress and the current emphasis of many heritage professionals on community participation, we strongly advise that these dynamics must be changed and that the program must be developed jointly with affected communities from the beginning of the project and not in subsequent steps, or (even worse) once the project already taken shape.  相似文献

This paper records a conversation that took place on Thursday 23rd November 2006 at the Museo del Hombre de Antofagasta de la Sierra (Museum of Man of Antofagasta de la Sierra), Catamarca, Argentina. The conversation involved different research groups co-investigating, each formed by a student of archaeology and a member of the personnel of the museum and/or other areas of the culture of the municipality of Antofagasta de la Sierra. Each presented the state of his/her enquiry into a particular object in the museum collection. The task was to tie stories to objects: stories by the elders of the town, the people who had discovered the item, the personnel of the museum and the texts written by archaeologists. This paper focuses on the conversation with Ernestina Mamaní, about a stone slab by Antofagasta elder, Don Anacleto Cháves, which she and Laura Roda had chosen to research.
Résumé Cet article rapporte une conversation qui a eu lieu le jeudi 23 novembre 2006 au Museo del Hombre de Antofagasta de la Sierra (Musée de l'homme d'Antofagasta de la Sierra), Catamarca, Argentine. La conversation mettait en scène différents groupes de recherche travaillant conjointement, chacun constitué d’un étudiant en archéologie, d’un membre du personnel du musée et/ou d'autres secteurs du service de la Culture de la municipalité d'Antofagasta de la Sierra. Chacun a présenté l'état de ses recherches autour d’un objet particulier des collections de musée. Il s’agissait d’accoler des récits aux objets: histoires rapportées par les anciens du village, les personnes ayant découvert l'objet, le personnel du musée et les rapports écrits par les archéologues. Cet article relate particulièrement la conversation avec Ernestina Mamaní, au sujet d'une dalle de pierre faite par un ancien d'Antofagasta, Don Anacleto Cháves, qu’elle même et Laura Roda avaient choisie pour leur recherche.

La consigna era anudar historias a cada objeto, historias ofrecidas por los ancianos del pueblo, los descubridores de la pieza, el personal del museo y los textos escritos por arqueólogos. Esta ponencia se focaliza en la conversación con Ernestina Mamaní, sobre una laja encontrada por un vecino de Antofagasta, Don Anacleto Cháves, que ella y Laura Roda habían elegido para investigar.
