What did peasants discuss at party meetings? Were they mobilized by ethnic politics or indifferent to them altogether? The end of the First World War brought about universal male suffrage in much of Europe, and with it the process of mass politics began. The concept of national indifference is important in understanding interwar politics, because this period is often studied teleologically with attention focused on extremism and nationalism as the primary mobilizing issue

Agrarian movements have been under-researched, and when Agrarians have been studied, it has been through the prism of elite politics. This comparative paper seeks to redress this omission by looking at grassroots rural politics. The interwar countryside was marked by profound political, economic and social transformation but also in terms of what Robert Paxton has described as the ‘triple crisis of the countryside’ – worsening economic conditions, the declining status of the countryside and inadequate political representation. The paper will explore how reform and crisis impacted how agrarian politics functioned at a local level by asymmetrically comparing cases from Romania, Poland and Ireland, with the final case helping to contextualize Eastern Europe within the wider European experience This paper argues that the rural population was mobilized, but primarily in the context of local issues rather than national ethno-political questions. Local party organization was, to paraphrase James C Scott, the site ‘of an exchange of small arms fire’ in rural class conflict, as questions regarding the control of public space, generational conflict and power within the village mobilized peasants. Thus, I argue that it was the underlying socio-economic issues that mobilized the rural population, not nationalism. The dynamics of these conflicts were shaped by local economic, political and social power dynamics, and by using indifference as a concept, we can look more deeply at interwar politics from a grassroots perspective and develop a more nuanced understanding of local, national and European politics.  相似文献

In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation.  相似文献

In the context of global warming, changes in extreme weather and climate events are expected, particularly those associated with changes in temperature and precipitation regimes and those that will affect coastal areas. The main objectives of this study were to establish the number of extreme events that have occurred in northeastern New Brunswick, Canada in recent history, and to determine whether their occurrence has increased. By using archived regional newspapers and data from three meteorological stations in a national network, the frequency of extreme events in the study area was established for the time period 1950–2012. Of the 282 extreme weather events recorded in the newspaper archives, 70% were also identified in the meteorological time series analysis. The discrepancy might be explained by the synergistic effect of co‐occurring non‐extreme events, and increased vulnerability over time, resulting from more people and infrastructure being located in coastal hazard zones. The Mann Kendall and Pettitt statistical tests were used to identify trends and the presence of break points in the weather data time series. Results indicate a statistically significant increase in average temperatures and in the number of extreme events, such as extreme hot days, as well as an increase in total annual and extreme precipitation. A significant decrease in the number of frost‐free days and extreme cold days was also found, in addition to a decline in the number of dry days.  相似文献

This paper presents a methodological tool of statistical correction to assess the capacities of different Roman amphorae, whereby ceramic values are transformed into amounts of transported product. Based on scaled drawings of 1281 Roman amphorae, individual vessels’ capacities have been calculated by applying a CAD software to the inner profiles. Each vessel has been classified according to amphora types and the mean for each type has been calculated to produce a coefficient called Average Capacity (AC). The estimated capacities are highly reliable and show narrow confidence intervals. Therefore, they can be applied immediately as a correction factor in studies of quantification of amphorae aimed at characterizing trading dynamics. As such, we expect that future statistical studies of amphorae will include this statistical coefficient to produce more precise and reliable analysis of assemblages and, consequently, more accurate research on the Roman economy.  相似文献

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.  相似文献

Este ensayo reporta sobre investigaciones entre un grupo de ni?os escolares brasile?os que fueron entrevistados para ver como ellos consideraban la arqueología, como su conocimiento del pasado afecta su comprensión del presente, y como su experiencia del presente les informa su vista del pasado.
Résumé Ce papier présente des recherches menées parmi un groupe d'écoliers brésiliens afin de savoir comment ils voient l'archéologie, comment leur connaissance du passé affecte leur compréhension du présent et comment leur expérience du présent renseigne leurs vues du passé.


[T]he miracle that we would hope for from the bottom of our hearts, the school as a preserved universe, island of purity—in which all disparities and social struggles would come to a stop, this miracle does not exist: the school is part of the world. (Snyders 1977:18)  相似文献

La conmemoración anual de la llegada de Colón a América como se experimenta en Argentina proporciona un foco para la definición de preguntas acerca de la comprensión de la arqueología como conocimiento. Para los grupos Indígenas es el aniversario del último día de la independencia de las poblaciones aborígenes. Los arqueólogos deben cuestionarse su posición cuando estudian el mundo y los objetos indígenas. Las interpretaciones de los “pioneros” arqueólogos argentinos son discutidas junto con el concepto de “la ruptura metafísica” sobre la que la arqueología construye su objeto, esa ruptura entre el mundo indígena subjetive y el mundo del conocimiento arqueológico. En el siglo XXI quedan preguntas pendientes acerca de la arqueología que, si es vista como una práctica descolonizadora, debe implicar su propio proceso de descolonización. Proporciona la Arqueología de Un Mundo el contexto para continuar esta tarea descolonizadora?
Résumé La commémoration annuelle de l'arrivé de Christophe Colomb en Amérique, comme c'est le cas en Argentine, donne l'occasion de se concentrer sur des questions de définition concernant la compréhension de l'archéologie comme source de connaissance. Pour les groupes autochtones, cette journée est la dernière de leur indépendance. Les archéologues devraient se demander comment ils se positionnent quand ils étudient le monde et les objets autochtones. Les interprétations des “pionniers” argentins de l'archéologie sont discutées en lien avec le concept de “d'écart métaphysique” sur lequel l'archéologie construit son objet: cet espace entre la réalité du monde des autochtones et des archéologues qui revendiquent la connaissance à travers la méthode scientifique. Au 21ième siècle, il y a encore des questions à demander concernant l'archéologie, qui même si elle est per?ue comme une pratique décolonisatrice, doit inclure le processus de décolonisation d'elle-même. One World Archaeology procure une contexte pour continuer cette tache de décolonisation?

During the 1970s, excavations were conducted in Alta Gracia, Córdoba, Argentina, in a compound that once was a seventeenth and eighteenth-century Jesuit Convent and is presently a museum. During the excavation, an amazing amount of historic material never studied before was discovered inside a sealed privy. After studying the material, we were able to identify the objects as once belonging to Santiago de Liniers, a man who successfully resisted and expelled British invaders from Buenos Aires. As a result, he was appointed Viceroy, though eventually he was shot in 1810 for confronting the Independence movement. Our hypothesis is that these objects were thrown into the privy as a gesture of contempt associated with his capture and execution.  相似文献
