New bird fossils from the Santa Cruz Formation (lower–middle Miocene), Santa Cruz Province, Patagonia, Argentina, are described. They represent an indeterminate species of the extinct anhingid Macranhinga and a new genus and species of basal Anatidae Ankonetta larriestrai. The record of the giant darter Macranhinga constitutes the southernmost record for the family, and expands the known stratigraphic range of the genus, previously restricted to the upper Miocene. Based on an analysis of the fossil anhingid record from South America, we hypothesize that giant darters disappeared from South America in the early Pliocene due to climatic deterioration, regression of marine and freshwater environments, the arrival of placental carnivorous mammals, and also probably by competition with phalacrocoracid cormorants. The new anatid Ankonetta is based on an incomplete but informative tarsometatarsus, with superficial similarities to extant Dendrocygna. A brief overview of several fossil ducks from the Patagonian Cenozoic concludes that most pre-Pliocene examples belong to non-anatine taxa, indicating that plesiomorphic ducks were the dominant anseriforms in those times, a pattern also evident on other continents.  相似文献

Squamata are known from South America since the Cretaceous, but their fossil record has an occurrence gap between the late Eocene and early Miocene. Fossils recovered from the Sarmiento Formation (Deseadan South American Land Mammal Age, late Oligocene) at Cabeza Blanca (45°S) partially fill this interval. The squamates recovered from Cabeza Blanca include both lizards (an indeterminate Iguanidae and a probable Iguaninae) and snakes (Madtsoiidae). If these taxonomic assignments are correct, the presence of an Iguaninae at such a latitude is unexpected because these lizards are presently absent from Argentine territory. The madtsoiid, here referred to Madtsoia, would extend the Cenozoic record of this genus back to around 16?Ma. The squamate fauna from Cabeza Blanca is compatible with warm and humid environments inferred for the Patagonian Deseadan.  相似文献

Over the past 20 years, the theoretical frameworks of population mobility studies have undergone profound changes. The redefinition of the term diaspora, the rise of transnational analysis, the formulation of the embodied experiences of migration, the increasing interest in migrants' attachment to places, gendered expectations and transcultural processes have coalesced to enrich knowledge. This article explores the culturally mediated experiences of migration and the individual change processes among the members of the Japanese community that from the 1960s onwards settled in the city of Las Palmas de Gran Canaria (Spain), a meeting point for East and West in the Mid-Atlantic. In spite of its small size, this community displays some characteristics that afford new conceptual insights into cultural in-betweenness. Our aim is to contribute to the burgeoning literature on migrants' sense and ways of being and belonging and on their experience of return, within the analytical framework of diaspora and transnationalism. This article makes use of an interpretative approach, and contrasts relevant local news items and biographical interviews with Japanese residents with the narrative texts of three returnees. This contrapuntal focus reveals their ambivalent sense of belonging ‘here and there’, their in-betweenness or their lives in aidagara.  相似文献

Current debates in radical urban studies and comparative urbanism focus in part on the denunciation of universalisation in urban theories as an expression of Eurocentrism. Decolonial and postcolonial scholars risk rejecting general theorising in the name of particularism, difference, and the fragmentary character of the world and reducing every urban policy transmission to the result of colonial relations. On the contrary, it would be more productive for radical scholars to pay attention to common pathways and universalist aspirations of anti-capitalist urban struggles. This paper traces the connections between three experiences of self-managed habitat production, developed by grassroots movements in Latin America and Europe. The comparative case study enables discussion of universalising aspirations of struggles against capitalist urban development. The paper concludes that collective and solidarity-based self-construction is a universal form of production of space, common to any culture at some point and to some extent, and that the self-managed production of habitat is a potentially universal paradigm for current anti-capitalist urban struggles.  相似文献

Cultural policy research exists in many contexts, asks many different kinds of questions and adopts a wide repertoire of research methodologies from a raft of academic discourses. This article investigates the research questions and approaches being undertaken by those working in this field. In order to achieve this, the article draws upon readings of contemporary publications in the field and on the authors’ experiences of building a research capacity in the area of cultural policy in a British – and, more particularly, a post‐devolution Scottish – university. The article traces the emergence of an academic discipline in the field, and seeks to advance this by reviewing a tripartite research agenda investigating: the history and historiography of cultural policy; the principles and strategies of cultural policy; and, the relationships between cultural policy and cultural theory/cultural studies.  相似文献

This article focuses on the idea that intervention in the labour market through the suspension of labour rights and freedoms, fear and a fall in purchasing power all played a key role in achieving political and economic objectives in the regimes of Mussolini, Hitler and Stalin. However, in each of these cases, the success of this policy was not as had been expected. These European experiences were essential for the configuration of the labour framework in the Franco dictatorship. The iron-fisted control of the labour market came to Spain through legal texts and institutions that were in many cases a blatant copy of those applied in Italy and Germany. In spite of the ideological distance between them, we can also find some common traits with Stalin's labour policies. The results obtained were even worse for Spain, and the negative effects on the economy were more serious, due to the greater longevity of the Spanish dictatorship.  相似文献

This article analyzes the mechanisms through which metropolitan governance is established in Montreal's aeronautics sector, one of the most important and innovative industries in the region. The article also examines the role of lead firms, socio‐economic actors, and public agencies from a territorial point of view. It is established that on the one hand the existence of a small number of prime producers at the local level facilitates productive linkages among businesses through subcontracting, and on the other hand, the intensive participation of intermediate socio‐economic agencies and organizations ensures a metropolitan anchoring of the sector and creates a strong territorial identity among the players.  相似文献

Several decades after the discovery of the spectacular Nahal Mishmar Hoard (a collection of cast metal goods, some quite ornate, found in a cave high in the cliffs of the Judean Desert) many important questions about Chalcolithic metallurgy in the southern Levant remain unanswered. What is the origin of the materials used? Where were the final goods produced and what were the dynamics of production? In fact, new questions have also arisen as recent discoveries force us to reconsider previous interpretations of Chalcolithic metallurgy and the societies within which it evolved. Such will be the focus of this paper.  相似文献

This article provides a comprehensive assessment of the effects of social protection interventions on material and subjective elements of well‐being. Drawing on a longitudinal survey located in two relatively deprived parts of Brazil, it assesses the effects of pensions and other cash transfers on the well‐being of older people and their households. This analysis is located within a dynamic economic and public policy context. The article finds that pension benefits significantly increase per capita income and that this is strongly associated with overall levels of satisfaction with household well‐being. Levels of reported subjective well‐being do not fall as respondents age, and the survey finds high levels of optimism about future well‐being. The positive effects of pension benefits were supported by upgraded health services and by more specific policies such as access to credit on favourable terms. Overall, the authors conclude that a combination of economic growth and effective public policies significantly boosted the well‐being of most households in their survey, and that Brazil can be taken as a model of good practice for other middle‐income countries.  相似文献

ABSTRACT This paper delves into the factors, which determine the attractiveness of regions in Europe for migrants. Contrary to the literature on the United States, which has increasingly focused on the role of amenities, existing research in Europe tends to highlight the predominance of economic conditions as the main drivers of migration. Differentiating between economic, sociodemographic and amenity‐related territorial features, we examine the appeal of various regional characteristics for migrants by analyzing net migration data for 133 European regions between 1990 and 2006. Our results show that, in addition to economic, human capital‐related and demographic aspects, network effects and—in contrast to existing literature—different types of regional amenities exert an important influence on the relative attractiveness of sub‐national territories across the European Union. Our findings therefore indicate that locational choices in Europe may be much more similar to place‐based preferences in the United States than originally thought.  相似文献
