Focusing on politics of culture in early socialist era, this article explores struggles for imposing particular visions of “folk” during the revolutionary zeal characterizing the post-1948 period's development in the discipline of Czechoslovak ethnography. It examines the self-proclaimed turn from previous ethnographic traditions, accused of bourgeois nationalism, to socialist orientation towards studying “true folk”. By tracing struggles around the re-conceptualization of constitutive criteria and boundaries defining the essential object of ethnographic inquiry, the socialist ethnographers readjusted to the changes by focusing on more “progressive” traditions and shifted towards the “working-class” seen as possessing revolutionary spirit and the true authentic essence of the nation. The article argues that the new ethnographic wave ultimately re-inscribed the essentialist categories they virtually combatted by embedding them within the same structural framework rooted in the national order of things.  相似文献

This article assesses the contemporary dynamics of transnationalism in Canada–US relations as the interaction of three key factors: market-driven or “bottom-up” economic integration, sectoral differentiation embedded in transgovernmental relations, and societal (or cultural) transnationalism. It also notes the disruptive and potentially transformative effects of transnational and transgovernmental forces beyond North America which are becoming increasingly central to the calculations of policymakers and major interest groups in both countries. It concludes that transnationalism is a multidimensional phenomenon that appears more likely to facilitate mutual accommodation between the US and its North American neighbors embedded within broader national and international policy streams than to build a broad North American consensus on policy harmonization for the foreseeable future.  相似文献

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

Wainman, C.C., Hannaford, C., Mantle, D. & McCabe, P.J., April.2018. Utilizing U–Pb CA-TIMS dating to calibrate the Middle to Late Jurassic spore-pollen zonation of the Surat Basin, Australia to the geological time-scale. Alcheringa XX, xx-xx.

Spore-pollen palynostratigraphy is commonly used to subdivide and correlate Jurassic continental successions in eastern Australia and thus aid the construction of geological models for the petroleum and coal industries. However, the current spore-pollen framework has only been tenuously calibrated to the geological time-scale. Age determinations are reliant on indirect correlations of ammonite and dinoflagellate assemblages from New Zealand, the North West Shelf of Australia and Southeast Asia to the standard European stages. New uranium-lead chemical abrasion thermal ionization mass spectrometry (U–Pb CA-TIMS) dates from 19 tuff beds in the Middle–Upper Jurassic Injune Creek Group of the Surat Basin enables regional spore-pollen palynostratigraphic zones to be precisely dated for the first time. These results show the base of the APJ4.2 and APJ4.3 subzones are similar in age to previous estimates (Middle Jurassic, Bathonian) from indirect palynostratigraphic correlation. However, the base of the APJ5 Zone and the APJ6.1 Subzone may be somewhat younger than previously estimated, possibly by as much as 2.5 and 4.2 Myrs, respectively. The continued utilization of U–Pb CA-TIMS dates will further refine the absolute ages of these zones, improve the inter- and intra-basinal correlation of Middle–Upper Jurassic strata in eastern Australian basins and greatly enhance intercontinental correlations.

Ferrari, M., El-Hedeny, M., Zakhera, M., El-Sabbagh, A. & Al Farraj, S., May 2018. Middle?Upper Jurassic marine gastropods from central Saudi Arabia. Alcheringa.

A total of 68 gastropod specimens are reported from the Middle?Upper Jurassic sedimentary successions exposed at central Saudi Arabia. The studied material comes from the Tuwaiq Mountain and Hanifa formations at the Khashm al Qaddiyah, Dirab, Jabal al Abakkayn and Maáshabah sections. Thirteen species are identified, described and illustrated. Among them, a new Aporrhais species (A. sauditica sp. nov.) is introduced. In addition, two further possible new Pseudomelania species from the same strata are mentioned. Other members of the assemblage include Kosmomphalus? sp. aff. K. reticulatus Fischer, Bourguetia? sp. aff. B. saemanni (Oppel), Bourguetia? sp., Ampullospira sp., Globularia? sp. cf. G. bajociana Fischer, Purpuroidea sp. aff. P. glabra Morris and Lycett, Purpuroidea sp., Cossmannea sp. aff. C. desvoidyi (d’Orbigny), Cryptoplocus sp. aff. C. depressus (Voltz) and Actaeonina? sp. Stratigraphically, seven species of this gastropod assemblage were only reported from the Middle Jurassic, whereas the other six ones are extending from the Middle to the Upper Jurassic of the studied succession. As compared with their gastropod content, the Khashm al Qaddiyah represents the richest section (33 out of 68 specimens, 48.5%), whereas the Maáshabah section showed an impoverished gastropod assemblage (only three specimens, 4.4%). The species reported here show paleobiogeographical affinities with coeval gastropod assemblages from India, east Africa, Middle East (Israel, the Sinai of Egypt) and western Tethys. The identified species confirm three depositional settings: open shelf lagoon, shoal/fore-shoal and open marine environments. The lower degree of fragmentation, poor sorting and scarcity of abrasion indicate a parautochthonous faunal assemblage.

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

Disc-like galls are reported on the Triassic corystosperm leaf Dicroidium hughesii (Feistmantel) Lele from the Parsora Formation of South Rewa Gondwana Basin, central India. Although there have been numerous reports of arthropod–plant interactions from Permian and Lower Cretaceous successions, this is the first unequivocal report of arthropod–plant interactions from the Triassic succession of Peninsular India. The new record adds to global evidence that arthropod herbivory and gall formation, in particular, had rediversified by the Late Triassic in the wake of the end-Permian mass extinction.  相似文献

This article analyzes a situation when the war was actually over and society began to recover. The government faced a severe challenge after the war. These serious problems will be analyzed in the light of the Great Northern War (1700–1721). The plans of the central government to stabilize society will be analyzed, as will the different kinds of planning activities undertaken by the authorities. The critical nature of the situation led the government to concentrate solely on short‐term planning. The government had no proper strategies; there were just a couple of exceptions to this rule. Firstly, the problems in Finland were repeatedly concrete and tangible. This made them both easy to address and essential to redress. Conditions in Finland became an issue of the first order. Even here decisions were dictated to a great extent by short‐term goals. Another strategy was connected with notion of the ‘primacy of the economy’. The government tried to deal with the problems by granting tax exemptions and reliefs, or correspondingly by cut‐backs in areas other than those that had been devastated. The machinery of government was not able to create anything new after the war, but its supervision of existing activities was excellent. This was important with respect to the allocation and use of the meagre resources.  相似文献

The aim of this article is to analyse the role played by Scandinavian politicians and experts working for the League of Nations in resolving conflicts to which Poland was a party and how this activity was assessed by Polish diplomats and politicians. Scandinavian involvement in decision-making processes related to Polish interests was mainly studied on the basis of diplomatic documents as well as Polish and Swedish press articles. The analysis focuses on several key issues. The first relates to the background to the involvement of Swedish politicians and experts in the procedures employed to resolve the PolishLithuanian conflict over Vilnius. Another concerns the attitude of the Scandinavian states towards electing Poland as a member of the League Council between 1923 and 1935, with special emphasis on the Swedish veto of 1926. Finally, the involvement of Scandinavian experts in resolving conflicts between Poland and the city of Danzig is discussed. In this case, the most important figure was Helmer Rosting, who held the position of the League of Nations High Commissioner in the Free City of Danzig between 1932 and 1934. The conclusions emphasize that Poles were generally dissatisfied with the work of the Scandinavians, accusing them of being biased towards the Germans and Lithuanians. Moreover, the Polish party involved believed that, when making their judgments and decisions, Scandinavian officials only followed the letter of the law and did not pay sufficient regard to the political context.  相似文献
