This paper analyses the use of the concept of territorial cohesion in policy documents produced by the European Union. It is an idea celebrated in community documents, such as cohesion reports, the Territorial Agenda of the European Union and the Green Paper on Territorial Cohesion; after more than a decade of political debate, the concept is about to gain a legitimate institutional role, after being included in the Lisbon Treaty, and is among the competences that the EU shares with other member states. At first, territorial cohesion seems to oppose the logics of neo-liberalism by reinscribing welfare problems and policies in spatial terms. However, using the analytical framework of cultural critics, and intending cohesion to be a discourse carried on by a community of European scholars and policymakers, the research will discuss the conceptual relationship between competitiveness and territorial cohesion in European policies and narratives.  相似文献

Cione, A.L. & Gouiric-Cavalli, S., June 2012. Metaceratodus kaopen comb. nov. and M. wichmanni comb. nov., two Late Cretaceous South American species of an austral lungfish genus (Dipnoi). Alcheringa 36, 203–216. ISSN 0311-5518.

Metaceratodus wollastoni, an Australian species, was reported from Upper Cretaceous beds of Patagonia in 1997. Later, three new species (Ceratodus wichmanni, Ptychoceratodus kaopen and Ptychoceratodus cionei), based on scarce material, were described from the same region. Two of these species were later referred to Ferganoceratodus. After examining much more abundant and better-preserved material, we conclude that neither the occurrence of Metaceratodus wollastoni nor those of Ptychoceratodus and Ferganoceratodus in the Cretaceous of South America are supported. We consider that C. wichmanni and P. cionei are synonyms and we reassign the three putative species to Metaceratodus under two new combinations: M. kaopen comb. nov. and M. wichmanni comb. nov. Both differ from the other species of the genus in having pits over most of the occlusal surface and a different occlusal profile of the tooth plate, and most have four ridges in the lower and upper tooth plates. Metaceratodus wichmanni differs from M. kaopen in oclussal profile, inner angle, and symphysis development among other features. Metaceratodus kaopen is known from the upper Santonian–lower Campanian Anacleto Formation of Río Negro province and M. wichmanni from upper Campanian–lower Maastrichtian units of Chubut, Río Negro, Neuquén and Mendoza provinces, Argentina. The occurrence of Metaceratodus in southern South America corroborates a close biogeographical relationship with Australia in the latest Cretaceous.

Indigenous mapping is a powerful political tool for long-marginalized populations to create visibility and establish land claims. In the case of Argentina, a country that was built on a denial of the presence of Indigenous peoples in the national territory, the emergence of these maps stemming from participatory processes coincided with the recognition of these communities' territorial rights in 1994. However, this mapping of Indigenous territories freezes extremely dynamic and complex socio-spatial realities just as it inflects their representations. In this paper, I reassess the weight and the role that Indigenous cartographic representations play in the evolution of these populations' spatial capital. Paradoxically, they give rise to more contradictions than they clarify. These paradoxes demonstrate the varied relationships different generations maintain with their territory, just as they concern its structure and its cartographic form. Therefore, based on the case of the Wichí of the Argentinian Chaco, this paper contributes to the understanding of contemporary issues of indigeneity by adopting a critical approach to Indigenous cartography. Whereas in Argentina cartographic knowledge is undergoing a process of decolonization, this does not apply to the legal system or to society as a whole.  相似文献

The first lungfish tooth plate from the Las Flores Formation, Chubut, southern Argentina, is described. This is the youngest ceratodontid known from the continent. In Africa, ceratodonts disappeared in the Eocene. Afterwards, they are only known from Australia until their extinction during the Pleistocene. The Las Flores tooth plate also represents the southernmost lungfish known since the Coniacian (early Late Cretaceous).  相似文献

This paper incorporates an experimental approach to the study of violence patterns in Northeastern Patagonia (Argentina) during the late Holocene. The underlying hypothesis considers a close association between socio-ecologic alterations during the Medieval Climatic Anomaly (MCA) (ca. 1150-600 years BP; Stine, 1994, 2000) and a probable increase in conflict levels. In order to test this hypothesis, human skulls (n = 986) were analyzed for bone lesions, discriminating late bone lesions, such as those produced by metal tools. The experimental approach used swine (Sus scrofa domestica) skulls, as proxies for human skulls, and incorporated original sabers. From this discriminating analysis, it can be inferred that no significant increase in violence signs were recorded until the first stages of Hispanic-indigenous contact (first half of 17th century). These findings emphasize the need for a revision of the implications of the dynamics of human populations in Northeastern Patagonia during the late Holocene.  相似文献
