This article explores the strategic use of literary form in the Mexican writings of José Zorrilla. The article focuses on México y los mexicanos (1856), a letter Zorrilla wrote to his fellow Spanish Romantic playwright, Ángel de Saavedra, the Duke of Rivas. Zorrilla’s México y los mexicanos is a rare piece of epistolary writing in Spanish Romanticism as well as one of the first literary histories of Mexico. Often overlooked in the letter, however, is Zorrilla’s economic critique of the precarious condition of artists in both Mexico and Spain. A conservative moderado, Zorrilla could not air his concerns publicly without the threat of retribution from his fellow conservative colleagues in Spain. Zorrilla thus used the epistolary form, the article argues, in order to surreptitiously introduce the economic plight of artists into mainstream Spanish as well as Mexican political discourse. Read in this context, Zorrilla’s letter makes visible the fundamental role a transatlantic Romantic vision of labour played in shaping nineteenth-century political discourse in both the Iberian Peninsula and Latin America.  相似文献

This paper describes environmental systems games developed for energy and water resource use designed to be adaptable from high school to undergraduate use. Two of the games are computer simulations with adjustable levels of difficulty that can be done in a computer lab or as a homework assignment. The third is a peer-to-peer roleplayer game designed for an immersive in-class simulation. For the energy and the peer-to-peer water games, we describe (1) the overall strategy or story line adopted, (2) the manner in which the game is played by students in a classroom setting, (3) the use of scientific literature in conceptualizing and parameterizing the game, and (4) possible game extensions. Preliminary data from use at the undergraduate level shows that the games are very well-received by students and, consistent with other research on quasi-experimental simulations, likely enhance learning outcomes.  相似文献

This article analyses European ‘youth riots’ as a social phenomenon after World War II. It also uses a specific riot – the 1948 Stockholm Easter Riots – in order to discuss the limits and potential of some theoretical assumptions underlying the field of historical contentious politics studies, primarily ‘contentious politics’ and ‘claims’. Using police reports and newspapers, the article shows that the riots were part of a European repertoire of post-war ‘youth riots’, but that they also bear similarities to an older popular repertoire of contention in Sweden. However, the riots do not really fit into the concept of ‘contentious politics’, as this concept is built on ‘claim-making’ as a key aspect and the participants did not make explicit claims. This leads to the conclusion that other theoretical tools, inspired by the concept of ‘moral economy’, are better suited for understanding the motivations of the rioters, whose actions are interpreted as a way of defending a perceived moral right of access to the urban public space.  相似文献

This article presents the life stories of six indigenous women from the Amazonian region, who coordinate local women processes through indigenous organizations and networks. Since the political and legal visibility of violence against indigenous women in Colombia is weak and limited, we aim to analyze their experiences from an intersectional perspective. For this purpose, we employed multiple methodologies, including body mapping and social cartography. Thus, by reconstructing their experiences and attempts to make visible violence against them, we could perceive some of its multiple modalities, which are quickly captured by the great category.  相似文献

As there is little research on the link between territories and interorganisational networks, this paper examines how the nature of a territory influences the characteristics of innovation networks. It compares the innovation network forms of two types of territories (high-altitude and medium-altitude mountain resorts) regarding four characteristics of networks widely debated in the literature: the nature of the relationships between members, the mode of regulation used, the architecture, and the geographical proximity of members. This research makes a significant contribution to both the spatial development and innovation management literature: indeed, our results show that according to the nature of the territory, innovation networks differ in terms of partners, geographical proximity, and regulation mode. However, the nature of the territory does not seem to influence the architecture of the innovation network since those networks need a hub organization that orchestrates the partners’ actions. These results, by providing a better understanding of the characteristics of innovation networks, help tourist territories to better attract customers.  相似文献

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.  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

It is important to determine the geological sources of Palaeolithic ambers in the south of Europe in order to understand the mobility and interchanges of prehistoric societies. Fourier transform infrared (FTIR) spectroscopy analysis carried out on Upper Palaeolithic ambers from La Garma A cave (Cantabria, Northern Spain) allowed us to identify their source area. Their diagnostic features were found to be similar to the amber obtained in the Lower Cretaceous outcrops close to this archaeological site, and to differ clearly from Baltic amber, which has been generally suggested as the amber found in European prehistoric sites. These results show that the origin of the Gravettian amber found in La Garma A is local and, consequently, a hypothetical contact route is not required to be able to account for the presence of this material in the Iberian Palaeolithic context studied here. For the first time it has been demonstrated that the provenance of an archaeological amber in the Iberian Peninsula is local, with both geographical and spectroscopical evidences. Our study also concludes that the archaeological amber of La Garma A possibly belongs to an araucariacean resin that originated from the coniferous forests which grew in the northeast portion of the Iberian Plate c.110-million years ago.  相似文献
