What makes a book political? This essay takes up this question through analysis of a small network of grassroots publishing projects. In doing so, I suggest that the materiality and mobility of a book can be just as, if not more, significant than its content when considering its political character. Specifically, I examine the interconnected trajectories of a cluster of books published since 2010 that participate in conversations about migration, work, and popular politics in Argentina and Bolivia. By zooming in on two very distinct contexts of book culture (Buenos Aires and La Paz) and especially the connections and tensions that emerge between them, I seek to account for some of the heterogeneous contemporary formations of what Ángel Rama called the ‘lettered city’ in Latin America. As I focus on grassroots publishing projects, I shift my attention away from the usual spaces of book culture, allowing other marginal circuits of production, circulation, and consumption to appear. Combining ethnographic narrative with textual analysis, this essay develops the double concept of political articulation (as expression and connection) to offer a transdisciplinary exploration of how movement is shaping the print book – materially and politically – in Latin America today.  相似文献

Distance‐based methods are applied in various fields of research. In this paper, a new relative distance‐based method, the W function, is introduced. This method contributes to the assessment of spatial patterns of economic activities using the stochastic Monte Carlo simulation, and supplements the typology of distance‐based methods recently drawn up by Marcon and Puech. The capability of the W function is compared with results from the Kd and the recently defined m function methods, which are widely used for monitoring the spatial distribution of economic activities by considering several theoretical and empirical examples. The W function appears to provide more precise estimations of the density of economic activities compared to the m and Kd functions, particularly in cases of complex patterns such as double clustered distribution. It also appears to provide a more accurate evaluation of dispersion.  相似文献

This paper looks at the St Kitts and Nevis Mummies' plays as published in Folklore by Roger Abrahams (1968). It demonstrates that the texts were originally taken from a play published by the Victorian children's author Mrs J.H. Ewing. This play appeared in several editions, most notably in two series issued by the Society for Promoting Christian Knowledge. Mrs Ewing's text was itself compiled from three northern English chapbook texts and a version from Silverton, Devon. The relative contribution of these texts to Mrs Ewing's play, and the way she put them together, are both explored.  相似文献

Two Early Devonian gastropod genera, Garraspira gen. nov. and Anoriostoma from the GarraLimestone, with sinistrally heterostrophic shells, share several shell features and are placed in the new tribe Anoriostomatini within the subfamily Agnesiinae. In contrast to the other members of the latter subfamily these genera represent a lineage in which the apertural slit was lost during evolution. This fact supports the opinion that the presence or absence of the apertural slit does not necessarily have significance for high-level taxonomy. Morphology of the gerontic whorl in Anoriostoma sinistra and Garraspira imtsitata suggests their limited mobility during the last ontogenetic stage.  相似文献

Southeastern Central Europe is quite rich in finds of progressive Neandertals from Middle Paleolithic contexts and early modern humans associated with evolved Upper Paleolithic (Aurignacian and Pavlovian). There are no human fossils that can be related to the transitional Middle-Upper Paleolithic units (the Bohunician and the Szeletian); thus, from anthropology we know only that the transitional period began with Neandertals and ended with modern humans. The archaeological record is more complex. The Jankovichian industries of Hungary differ from the mostly non-Levallois Middle Paleolithic of Central Europe in the presence of some Levallois; they seem to be technologically related to the Levallois-Leptolithic Bohunician industries of Moravia, dated to 43,000–38,000 B.P., which are the first transitional Upper Paleolithic unit. The appearance of the Szeletian before 42,000 B.P. in Hungary and at about 39,000 in Moravia represents a technological variation of the transition, although retaining marked local Middle Paleolithic elements. The date of the appearance of the typical Aurignacian, the first culture clearly related to modern humans, is unclear, but it certainly developed after 36,000 B.P. and has several dates between 35,000 and 30,000 B.P.  相似文献

This paper aims at the comprehension of feasible development trajectories conceptualized within the new path-development model in the case of two less developed regions in Central Europe (CE). The main new element of this paper comprises the examination of the perception of key barriers and mechanisms hindering particular evolutionary trajectories by regional stakeholders and their comparison with those conceptualized in the literature. Although conceptual characteristics of prevailing path types in different regional innovation systems do exist, empirical verification from less developed regions such as those in CE is insufficient. On the basis of interviews with regional stakeholders, a typology of barriers for pathways conceptualized to date was elaborated from a CE perspective. Our study showed that the feasibility of a more radical path is hindered by a wide range of barriers operating at different levels. The elaborated typology of barriers for various path-development trajectories outlined the main hindrances constraining key regional actors, linkages and institutions. Given the general weakness of the overall RIS, path-extension and path-modernization trajectories are bound to be the most realistic options for this type of less developed regions. Our study revealed existing regional dynamics as built predominately upon incremental changes within rooted but prospective industrial branches.  相似文献

Ginalski-type E5 button spurs made from a Cu alloy are a characteristic attribute of the Middle Roman period in barbarian Europe. The find of part of a mould made of non-ferrous metal at the Luleč site in the district of Vyškov, Czech Republic, provided key evidence for explaining the issue of their production. The discovery of this unique artefact showed that based on current knowledge, the spurs made from a Cu alloy were also produced in the Middle Danube region and not only in Northeast Europe as had previously been thought.  相似文献
