Graphic and metric information about the site and its environment and about the different structures and artefacts located are indispensable for the optimal management of an archaeological excavation. A Geographic Information System (GIS) proves useful in managing and analysing information and data obtained from different sources. Two techniques of data capture, Terrestrial Laser Scanning (TLS) and close range photogrammetry, are used to generate accurate and high-resolution 3D models of a cave, the silos and a combustion structure at the Can Sadurní site (Begues, NE Spain). This site is especially noteworthy on account of its complete stratigraphy of the Catalonian Holocene. The capture and processing of the photogrammetric and TLS data used to generate 3D models are discussed in detail. These models cannot be obtained by classic archaeological techniques since the record is made layer by layer, approximately one decimetre apart, with the result that the information between the layers is lost. Our findings highlight the potential of these techniques for obtaining accurate and photorealistic models that facilitate a complete analysis of the available information at an archaeological site. 相似文献

This essay argues that the individual nature of the sketch of manners (cuadros de costumbres) imagined, in the midst of post-war politicisation of the popular classes, a dismantling of alliances of class and race to privilege a single possible image of community: the nation. By reconstructing the discourses – in particular of José María Vergara y Vergara and Ramón Páez – that facilitated the production of the llanero type in Venezuela and the Indian (indio) type in Colombia, this essay posits the sketcher as embodying a ‘patrician mindset’. As a product of it, the sketchers project their own personal histories onto their representations of the people and, in so doing, erases the frontier histories of these populations. By confounding the history of the nation with their own histories, Vergara y Vergara and Páez equated ‘patria’ with patrimony, producing peaceful populations as ‘pueblo’ (national people). Paradoxically, these idyllic portraits of the ‘pueblo’ belie an all but peaceful principle of authority that these post-independence patricians used to legitimise themselves. 相似文献

In this paper we try to throw some light on the Knightian distinction between risk anduncertainty attending to a number of previous contributions to philosophy and economics. On the economists' side, we propose to read Knight's distinction in the light of the distribution controversy that took place in theQuarterly Journal of Economics at the end of the xixth century. On the philosophers' side, the pair risk/uncertainty can be analysed in view of Knight's epistemological sources, as opposing a sort ofprobabilistic positivism to anagnostic variety of positivism. His philosophical commitments can be of use in explaining why Frank Knight closes down the distribution controversy, proposing instead a reconstruction of economics as a rational choice science. 相似文献

COMPLEMENTARITY BETWEEN LOCAL KNOWLEDGE AND INTERNATIONALIZATION IN REGIONAL TECHNOLOGICAL PROGRESS*
Enrique Lpez‐Bazo Francisco Requena Guadalupe Serrano 《Journal of regional science》2006,46(5):901-929
ABSTRACT Trade, foreign direct investment, and inter‐regional R&D spillovers facilitate competition, the spread of knowledge, and the adoption of more advanced technologies, which in turn hastens total factor productivity (TFP) growth. The spread of these efficiency gains from internationalization requires a sufficient local knowledge to enable them to be adapted to the domestic productive environment. Thus, higher local knowledge and internationalization will lead to TFP growth, and the greater the complementarity between variables the higher the TFP growth. We test the complementarity hypothesis using Spanish regional data over the period 1980–1995 in which both regional local knowledge and internationalization experienced a notable increase. 相似文献

This article focuses on how educational institutions are crucial sites for understanding how racial capitalism and anti-Black violence are reproduced. Centring Chapel Hill, home of the University of North Carolina (UNC), and its neighbouring town of Carrboro as a university town built by racial capitalist and anti-Black practices, I analyse how the university functions as a social reproductive force that structures the town and its local public education system. Building on my ethnographic research, Black studies literature, and Black geographic thought, I argue that the university partakes in the political, economic, and ideological restructuring of a community that enables hierarchical differences to be produced in schools in terms of how success is rooted with liberal notions of the individual and proximity to whiteness. Paying attention to these relationships challenges us to think about the need for the total eradication of oppression in all forms to truly have liberated educational spaces. 相似文献

ABSTRACTNever before have the layout, the text format, and support been as important as they are today. Studies reflecting on the relationship between the meaning of the literary text and its form have rapidly increased. This kind of study has focused mostly on the history of the reading process and the history of the book as well as on the possibilities of new technologies in the literary field. However, none of these approaches has reached the point of creating a comprehensive methodology for the analysis of the relationship between the message and its channel. This work is intended to propose a methodology of analysis based on some concepts such as peritexts (Genette) and visuo-graphic zone (Cárdenas). 相似文献

Behind the conjunctural growth of popular economies in Brazilian cities lies a set of entangled disputes over urban density with important political consequences. While popular economic agents are repressed by local governments, informal work hired through digital platforms grows exponentially and engenders new precarious forms of assembling labour relations in, and extracting value from, global South cities. The contrasts and indirect relations between digital platforms and popular economic agents are important in understanding the growth of platforms, which hinges on accessing low-wage workers whose attempts to make an independent living are otherwise prohibited. This dynamic has resulted in the political mobilisation of popular economy agents and their alliances with urban social movements. Through this paper, I examine how their networking and particular disputes for a right to the city hold potential for the emergence of other economies. 相似文献
