Oxygen isotopes in shell carbonate samples from the marine rocky‐shore intertidal gastropod Monodonta turbinata (Born) are investigated in both modern analogue specimens and in archaeological specimens from the Grotta dell’Uzzo (Sicily). Variations in shell edge values of δ18O in living specimens collected monthly over two years are closely correlated with monthly seawater temperatures measured at the time of collection, showing that the species can be used for palaeoseasonality studies. Analyses of shell edge δ18O values in archaeological specimens, from Mesolithic through to early Neolithic phases at the Grotta dell’Uzzo, enabled the inference of various seasons of collection of shellfish and how such seasonality varies between the different phases of occupation. Interesting similarities and differences exist between the seasons of marine shellfish exploitation and the seasons inferred from the vertebrate zooarchaeological assemblages. A major inference drawn from the analyses and discussion is that the exploitation of all marine resources (fish and shellfish) increased in the later Mesolithic and early Neolithic periods.  相似文献

Nietzsche is generally regarded as a severe critic of historical method and scholarship; this view has influenced much of contemporary discussions about the role and nature of historical scholarship. In this article I argue that this view is seriously mistaken (to a large degree because of the somewhat misleading nature of Vom Nutzen und Nachtheil der Historie für das Leben). I do so by examining what he actually says about understanding history and historical method, as well as his relation to the founders of modern German historiography (Wolf, Niebuhr, Ranke, and Mommsen). I show, contrary to most expectations, that Nietzsche knew these historians well and that he fundamentally affirmed their view of historical method. What he primarily objected to among his contemporaries was that historical scholarship was often regarded as a goal in itself, rather than as a means, and consequently that history was placed above philosophy. In fact, a historical approach was essential for Nietzsche's whole understanding of philosophy, and his own philosophical project.  相似文献

Sir Stafford Northcote has gone down in history as a man who fell short of the ultimate achievement of being prime minister largely because of personal weakness, and lack of political virility and drive. The picture painted by Northcote's political enemies – most notably the Fourth Party – has been accepted uncritically. Yet, political motives lay behind the actions of these supporters, and their harsh black and white portrait is not illustrative of the complexity of the situation in which Northcote found himself. Although individual characteristics undoubtedly played a part in his final political failure, underlying dynamics and structural transformations in politics and political life were more significant. It was more than simply the misfortune in succeeding the exceptionally charismatic Disraeli as leader. Northcote was faced with unparalleled disruption in parliament from Irish Nationalist MPs; the starkly polarised debate on the eastern question left him detached as a moderate. His temperament was better suited to constructive government rather than to opposition. However, following general election defeat in 1880, Northcote was denied this opportunity. Equally, his position in the lower House denied him the capacity to define a clear political critique of the Liberal government. Northcote's leadership of the party reflected the changing nature of British politics as radicals, tories, Irish Nationalists and Unionists increasingly contested the consensual style more appropriate to the political world of Palmerston and the 14th earl of Derby.  相似文献

The Supreme Court's 5–4 decision in the Passenger Cases (1849) overturned two Northern states' taxes on poor foreign immigrants. The Court's eight opinions disputed whether destitute transatlantic immigrants arriving in U.S. ports were legally and constitutionally “persons” like fugitive slaves fleeing the South, free African Americans residing in the U.S.‐Canadian borderlands, and black seamen working on ships entering Southern ports. The eight opinions issued in the case, as Charles Warren noted, raised fundamental constitutional questions concerning whether U.S. congressional or state authority was exclusive or concurrent over persons moving in interstate and international business, reflecting wider sectional struggles fostering the Civil War. 1 More recently, Mary Bilder and others examined connections among indentured contract labor, race‐based American slavery, and the Court's antebellum Commerce Clause decisions to establish that foreign immigrants were commercial objects subject to regulation through the Constitution's Commerce Clause. 2 Southerners and Northern pro‐slavery supporters argued, however, that fugitive slaves and free blacks crossing interstate and international borders were “persons” who could be regulated or altogether excluded under state police powers. 3  相似文献

Remote dryland regions are characterised by sparse populations and socially marginalised voices which pose particular challenges to natural resource management. This paper considers the issue of how to achieve community engagement in regions with these characteristics. In doing so, the paper contributes to an expanding international research agenda focusing on the distinct characteristics of arid and semi‐arid regions under the heading of ‘dryland syndrome’. The paper draws on government liaison officer and local community perspectives of successful engagement in the case‐study region of Lake Eyre Basin, Australia. The results demonstrate that widely recognised characteristics of successful engagement are required but insufficient for genuine engagement in remote dryland regions. In addition to building trust through community ownership, being inclusive, effective communication, and adequate resources, genuine community engagement in drylands also requires respecting the extreme conditions and extraordinary variability of these areas. Residents of dryland regions seek genuine engagement yet engage opportunistically when seasons are conducive and when tangible outcomes are visible.  相似文献

Using information collected in a questionnaire survey, this study investigates the factors influencing the housing tenure of Ghanaian immigrants in Toronto. The study finds that Ghanaian immigrants have a low home-ownership rate compared to the Canadian-born population and other immigrant groups. This is partly attributable to the recency of their migration, their relatively low incomes, and their small household sizes. Analysis also shows that social and personal factors, notably the initial motives of the immigrants, their back-home ties, their desire for home ownership back home, and their intention to return there permanently, are critical in shaping their decisions with respect to home ownership in Canada.
Dans cette étude, nous examinons, à l'aide d'un sondage, les facteurs portant sur les modes de logement des immigrants ghanéens à Toronto. Nous démontrons que les Ghanéens sont propriétaires de leurs logements moins souvent que ne le sont les personnes nées au Canada ou les membres d'autres groupes d'immigrants. Le sondage révèle que la taille inférieure des ménages, les faibles revenus, et les dates d'immigration récentes des immigrants ghanéens sont parmi les causes principales de ce phénomène. L'analyse démontre aussi que des éléments sociaux ou personnels, tels les raisons initiales de l'immigration, les liaisons avec le lieu d'origine, le désir d'être propriétaire dans le lieu d'origine et l'intention ou non des immigrants de retourner au Ghana, sont d'une importance fondamentale lorsque les immigrants ghanéens prennent une décision à l'égard de l'achat d'un logement.  相似文献
