ABSTRACTThis paper examines how Canadian political science portrays Atlantic Canada, along with some of the consequences of persistent misrepresentations. I first explore traditional portrayals of Atlantic Canada as well as arguments challenging those conceptions, demonstrating that it is no longer appropriate to treat Atlantic Canada as primarily defined by either economic processes or common political culture. I then survey the Canadian Journal of Political Science, Canadian Public Administration and Canadian Public Policy to determine the extent to which discussions of Atlantic Canada still, (a) emphasize economic phenomena, and (b) assume a common Atlantic political culture. I find that, while political scientists are now less likely to study the region in terms of economic phenomena, they still perpetuate outdated depictions of Atlantic political culture. This tendency results in a certain degree of methodological imprecision and reinforces problematic assumptions about Atlantic political life. 相似文献

Significant political and economic developments among the Chumash of southern California were catalyzed in part by the emergence of an intensive, specialist-driven shell-bead industry during the second millennium CE on the Santa Barbara Channel Islands. The production of millions of beads depended in turn on the availability of lithic microdrills of standardized form and materials. Channel Islanders quarried a particular stone type, a blocky Monterey Formation chert, from multiple outcrops situated close to the eastern shores of Santa Cruz Island. Rich archaeological assemblages document the lithic and shell byproducts of these intertwined production systems, each of which endured for several centuries (CE 1150–1819). Islanders invariably chose Island chert for making microdrills: hundreds of thousands of specimens recorded to date are of this material. Furthermore, nearly every microlith in all of Chumash territory (post CE 1150) was produced on the islands; the large populations on the mainland did not participate in microlith making or bead making after CE 1150–1200. We argue that this pattern had its roots not only in the patchiness of key resources and shifting regional social relationships, but also in the physical properties of available raw materials. Here we experimentally assess the properties of Santa Cruz Island chert alongside three important mainland raw materials—Grimes Canyon fused shale, Coso obsidian, and Vandenberg chert—that potentially could have been tapped to make microliths. We test the proposition that Island chert outperforms other lithic materials in drilling efficiency and drill use life. Our experimental results from 108 drilling trials reveal sharp distinctions in performance characteristics across the four materials. We infer that the process by which Islanders became the more-or-less exclusive manufacturers of shell-bead currency in southern California was facilitated by both the efficacy and physical properties of the Island cherts and the propitious locations of the outcrops. 相似文献

Proterosuchid archosaur remains from the Early Triassic Bulgo Sandstone of Long Reef,New South Wales
Benjamin P. Kear 《Alcheringa: An Australasian Journal of Paleontology》2013,37(4):331-337
Two associated anterior dorsal vertebrae of a primitive archosaur are described from the Early Triassic (Dienerian–Spathian) Bulgo Sandstone at Long Reef, New South Wales, Australia. Character states including anteroposteriorly elongate centra, dorsal neural spines with height greater than length, the possible presence of intercentra, double-headed rib articulations and well-developed apical tables on the neural spines suggest affinity with proterosuchid archosauriforms and permit some comparisons with previously described Australian taxa. The Bulgo Sandstone vertebrae represent the first record of archosaurian body fossils from the Sydney Basin and are one of only a handful of occurrences thus far documented from the Triassic of Australia. 相似文献

The isolated scapula of a chelonioid sea turtle is described from the Upper Cretaceous (upper Maastrichtian) Miria Formation of the Giralia Ranges in Western Australia. Character states including the wide angle of divergence between the scapular processes (possibly reaching 140°), projection of the glenoid on a constricted scapular neck, and highly vascular glenoid articular surfaces suggest affinity with dermochelyoids—the most diverse and geographically widespread clade of Mesozoic chelonioids. The Miria Formation chelonioid scapula constitutes the first definitive record of a Late Cretaceous sea turtle from Australia and is one of the few occurrences thus far documented from Upper Cretaceous–Paleogene deposits in the Southern Hemisphere. 相似文献

Pterosaur remains are very rare in Australasia and especially in Upper Cretaceous strata. Thus, the discovery of a jaw fragment from the Cenomanian–Coniacian Molecap Greensand near Gingin in Western Australia represents an important new stratigraphical occurrence for the region. Although the teeth are not preserved, the presence of labio-lingually compressed alveoli that are anterolaterally oriented, variable in shape/size (inferring heterodonty) and very widely spaced is reminiscent of ornithocheirids—a geographically cosmopolitan clade of predominantly Early Cretaceous pterodactyloids. If correct, this identification could extend the known range of Ornithocheiridae through to the Late Cretaceous in the Southern Hemisphere. 相似文献

China’s economic reforms have exacerbated the problems of over‐grazing and desertification in the country’s pastoral areas. In order to deal with rangeland degradation, the Chinese government has resorted to nationalization, or semi‐privatization. Since the implementation of rangeland policy has proved very difficult, however, experiments with alternative rangeland tenure systems merit our attention. In Ningxia, in northwest China, local attempts have been undertaken to establish communal range management systems with the village as the basic unit of use and control. Some of these management regimes are under severe stress, due to large‐scale digging for medicinal herbs in the grasslands. This digging has resulted in serious conflicts between Han and Hui Muslim Chinese, during which several farmers have been killed. It is against this backdrop that this article explores the institutional dynamics of range management in two different villages. 相似文献

Two macropodoid endocranial casts from the early Miocene of the Riversleigh World Heritage Area, northwestern Queensland are described. The larger is associated with a fragmentary cranium and is attributable to the balbarine kangaroo Balbaroo. The smaller more complete specimen was found as an isolated endocast and cannot be confidently identified beyond superfamily level. The external neurocranial morphology of both specimens closely resembles that of plesiomorphic macropodoids and indicates a basal ‘macropodid-grade’ level of complexity. Development of the visual region of the neocortex suggests that crepuscular-nocturnal habits might have been present in early Miocene kangaroos. 相似文献
