A number of trends in recent immigration to Canada are discussed: the scale of contemporary movement; the transformation of national origins over the past generation; the diversity of entry classes and the lack of any singular immigrant condition; the remarkable contraction of immigrant destinations to a few large cities; the contribution of immigration to population growth and housing demand in these metropolitan areas; and the distinctive geography of the various entry classes, with higher-status arrivals disproportionately located in Vancouver. The remainder of the paper considers and rejects two common myths in the discussion of immigration: first, the myth of an immigrant underclass, and second, the myth of an immigrant overclass. Using research from Vancouver associated with the Metropolis Project, the first myth is challenged from an analysis of Census data that emphasizes the social context of immigrant life and upward mobility; the second myth is shaken by a qualitative methodology that reveals the unexpectedly fragile experience of a number of business immigrants. Certaines tendances relatives à l'immigration récente au Canada sont examinées: l'envergure des déplacements actuels, les changements dans l'origine nationale des immigrants au cours de la dernière génération, la diversité des catégories d'immigrants admis et, par conséquent, l'absence d'une seule condition pour tous, le fait que les immigrants choisissent essentiellement de s'établir dans quelques grandes villes, la croissance de la population et la demande en logement attribuables aux immigrants dans ces régions métropolitaines, et les choix géographiques distincts des immigrants selon leur catégorie à l'admission, comme c'est le cas de Vancouver, qui accueille un nombre disproportionné d'arrivants de statut élevé. Dans le reste de l'article, les résultats d'études effectuées dans le cadre du Projet Métropole permettent d'examiner puis de réfuter deux mythes communément associés à l'immigration au Canada: l'existence d'un sous-prolétariat et celle d'une classe dominante d'immigrants urbains. D'abord, l'existence d'un sous-prolétariat est rejetée suite à l'analyse de données tirées du recensement concernant le contexte social entourant les immigrants et la mobilité sociale ascendante de la plupart des nouveaux arrivants. Ensuite, une méthode qualitative met en lumière une découverte surprenante: la fragilité de l'expérience de la prétendue classe dominante – les immigrants qui travaillent dans le monde des affaires.  相似文献

Animal bone assemblages from four historical sites in eastern Massachusetts are analysed in a comparative framework to interpret aspects of urban food systems. Characteristics of the urban environment and the nature of food supply and exchange systems are interpreted from taxonomic representation, body part representation, butchery patterns, and age and seasonal slaughtering patterns. These analyses show that specialized husbandry to supply urban markets was limited during the seventeenth and eighteenth centuries, and that many aspects of urban food distribution systems followed traditional rural patterns. A model that explores the relation between patterning of bone collections and characteristics of urban areas is applicable to other studies of urban assemblages. © 1997 by John Wiley & Sons, Ltd.  相似文献

This article treats three themes: how Labour planned and fought the 1929 election, to whom it appealed and the results. It draws upon the MacDonald Papers, National Executive Committee minutes, the Daily Herald, London News, Labour sources in book form, electoral materials and secondary sources. It discusses the party's tactics and strategy for progress, funding and influences on its campaign. Such influences included the 1927 Trade Union Act, the Cheltenham agreement (1927) with the Co-operative Party and the appearance of the Liberal counter-cyclical economics proposals. The article argues that Labour's perceived base was wider than expected. Women and the rural classes, including farmers, were emphasized as target groups. Labour thought the key to a majority lay in the countryside. An investigation of the results from 1929 seems to imply this was not strictly the case, but there was a number of such constituencies which Labour was close to gaining. The Liberal revival helped Labour in the rural areas. Central planning was a light touch in 1929. It did, however, involve setting the framework for the campaign and making policy on all of the matters referred to above.  相似文献

NATO's nuclear deterrence posture has since the late 1950s involved risk‐and responsibility‐sharing arrangements based on the presence of US nuclear weapons in Europe. Since 1991 gravity bombs, deliverable by US and allied dual‐capable aircraft, have been the only type of US nuclear weapons left in Europe. Although many other factors are involved in the alliance's deterrence posture and in US extended deterrence—including intercontinental forces, missile defences, non‐nuclear capabilities and declaratory policy—recent discussions in the United States about NATO nuclear deterrence have focused on the future of the remaining US nuclear weapons in Europe. The traditional view has supported long‐standing US and NATO policy in holding that the risk‐ and responsibility‐sharing arrangements based on US nuclear weapons in Europe contribute to deterrence and war prevention; provide assurance to the allies of the genuineness of US commitments; and make the extended deterrence responsibility more acceptable to the United States. From this perspective, no further cuts in the US nuclear weapons presence in Europe should be made without an agreement with Russia providing for reductions that address the US—Russian numerical disparity in non‐strategic nuclear forces, with reciprocal transparency and verification measures. In contrast, four schools of thought call for withdrawing the remaining US nuclear weapons in Europe without any negotiated Russian reciprocity: some military officers who consider the weapons and associated arrangements unnecessary for deterrence; proponents of ambitious arms control measures who accept extended deterrence policies but view the US weapons in Europe as an obstacle to progress in disarmament; nuclear disarmament champions who reject extended nuclear deterrence policies and who wish to eliminate all nuclear arms promptly; and selective engagement campaigners who want the United States to abandon extended nuclear deterrence commitments to allies on the grounds that they could lead to US involvement in a nuclear war.  相似文献

Mediterranean history, and the history of other closed seas, is seen here as the experience of those who traversed the sea and arrived as decentered aliens on the other side. Mainly these have been men, with merchants generally as pioneers who introduced the goods, ideas, and religion of one region to another. From antiquity onwards, port cities such as Carthage, Alexandria, Smyrna, and Livorno acted as links among the three continents facing the Mediterranean, and visitors from other lands were sometimes free to roam, sometimes ghettoized.  相似文献

Abstract

The map of Tenochtitlan published along with a Latin version of Hernán Cortés's letters (Nuremberg, 1524) was the first picture Europeans had of the Culhua‐Mexica city, the capital of the Aztec empire. The source of this woodcut map is unknown, and the author argues here that it was based on an indigenous map of the city. Once published in Europe, the city map and its companion map of the Gulf Coast, while certainly documentary, also assumed a symbolic function in supporting Cortés's (and thereby Spain's) just conquest of the Amerindian empire.  相似文献

Cantrill, D. J., & Drinnan, A. N., 1994:03:28. Late Triassic megaspores from the Amery Group, Prince Charles Mountains, East Antarctica. Alcheringa 18, 71–78. ISSN 0311-5518.

Megaspores referable to the genera Cabochonicus Batten & Ferguson 1987 and Minerisporites Potonié 1956 are a common component of the palaeoflora recovered from the Jetty Member within the Flagstone Bench Formation of the Amery Group. The known ranges of these two genera, in conjunction with the macrofloral remains, suggest a Late Triassic age. Two new species, Cabochonicus sinuosus and Minerisporites triangulatus, are described. Scanning electron microscopic examination of the spores indicates that standard palynological treatment of megaspores can result in sculptural degradation, possibly leading to incorrect generic assignment.  相似文献
