Using multivariate techniques, several skulls of fossil large canids from sites in Belgium, Ukraine and Russia were examined to look for possible evidence of the presence of Palaeolithic dogs. Reference groups constituted of prehistoric dogs, and recent wolves and dogs. The fossil large canid from Goyet (Belgium), dated at c. 31,700 BP is clearly different from the recent wolves, resembling most closely the prehistoric dogs. Thus it is identified as a Palaeolithic dog, suggesting that dog domestication had already started during the Aurignacian. The Epigravettian Mezin 5490 (Ukraine) and Mezhirich (Ukraine) skulls are also identified as being Palaeolithic dogs. Selected Belgian specimens were analyzed for mtDNA and stable isotopes. All fossil samples yielded unique DNA sequences, indicating that the ancient Belgian large canids carried a substantial amount of genetic diversity. Furthermore, there is little evidence for phylogeographic structure in the Pleistocene large canids, as they do not form a homogenous genetic group. Although considerable variation occurs in the fossil canid isotope signatures between sites, the Belgian fossil large canids preyed in general on horse and large bovids.  相似文献

This article examines the evolution of the nuclear enterprises in Russia and Ukraine after the break-up of the USSR in 1991 to the present and contributes to better understanding of interrelation between large-scale technologies and politics. It compares how economic crises and recovery, political considerations, and nuclear imaginaries – visions of the role that nuclear power will play in conceptions of a national future – have determined the direction of nuclear energy policy. It explores institutional, legal, and other developments surrounding the 34 operating power reactors in Russia and 15 in Ukraine including promotion and regulation; operation; license life extension; decommissioning and spent fuel and waste handling. Russia and Ukraine are connected by history, Soviet reactor technology, and nuclear fuel and waste disposal agreements that shape and constrain the countries’ behavior, and leave great uncertainty for the future given the ongoing conflict between the two nations. Yet both nations hope for some grand nuclear ‘renaissance.’  相似文献

Tooth wear is a common phenomenon in archaeological material. It has been related to the abrasiveness of diet and to the tribological attrition of teeth of individuals. Numerous investigations have been carried out in north and middle American samples as well as African anthropological material. Not much is known about tooth wear in European cultures. Eleven skulls from Chervona Gusarovka, and 14 skulls from the Upper Saltov sites of the Khazar Kaganat region (8th–10th centuries AD) in eastern Ukraine, with different diets were examined. A total of 208 teeth were studied for tooth wear, caries prevalence and periodontal status. Abrasion grades were determined according to a standardised classification and statistically evaluated. Periodontal status was measured using the distance between the enamel‐cementum junction and alveolar crest and the gingival attachment level respectively. Tooth wear was significantly different (P < 0.01) between the two populations. A low caries prevalence of 4.2% in the Chervona Gusarovka population and 1.7% in the Upper Saltov population was found. Significantly more alveolar crest bone resorption on the lingual side was found in the premolars and anterior teeth of the Chervona Gusarovka population. No significant differences were found regarding gingival attachment levels and gingival recession. It is concluded that the content and mode of food preparation influenced tooth wear, as reflected by the prevalence of dental caries and periodontal diseases in these ancient populations.

ABSTRACT

Some states create geographical imaginaries that envision the homeland as coherent and good, and the spaces of Others as disordered, dangerous and therefore legitimate objects of violence. Such ‘violent cartographies’ serve not only to justify policy actions, but constitute bordering practices aiming to provide stability, integrity and continuity to the Self, sometimes referred to as ‘ontological security’. This article examines the role of creativity and artistic imagination in challenging dominant geopolitical narratives. It examines satire on the Russian-language internet, which played upon the Russian state’s geopolitical narrative about the war in Ukraine 2014–15. Three themes within this dominant narrative – (1) the imperialist idea of Russia as a modernising force, (2) the gendering of Ukraine as feminine and Europe as homosexual and (3) the idea that the current war was a re-enactment of Russia’s historical battle against fascism – all became the object of fun-making in satire. I argue that satire, by appropriating, repeating but slightly displacing official rhetoric in ways that make it appear ridiculous, may destabilise dominant narratives of ontological security and challenge their strive towards closure. Satire may expose the silences of dominant narratives and undermine the essentialism and binarism upon which they rely, opening up for estrangement and disidentification.  相似文献

The Russian military interventions in Ukraine, which have led to the annexation of the Crimean peninsula and to the entrenchment of separatist enclaves in Donetsk and Luhansk provinces, directly challenge the post‐Cold War European state system. Russia has consistently denied any wrongdoing or illegal military involvement and has presented its policies as a reaction to the repression of ethnic Russians and Russian speakers. This article argues that it is important to examine and contest unfounded Russian legal and political claims used by Moscow to justify its interventions. The article proceeds to assess in detail three different explanations of the Russian operations in Ukraine: geopolitical competition and structural power (including the strategic benefits of seizing Crimea); identity and ideational factors; and the search for domestic political consolidation in Russia. These have all played a role, although the role of identity appears the least convincing in explaining the timing and scope of Russian encroachments on Ukrainian territorial integrity and the disruption of Ukrainian statehood.  相似文献

Living humans are unique among the animal kingdom with respect to their ability to externalize mental representations outside the brain through a variety of media and in a recursive or creative manner (i.e., generating a potentially infinite array of combinations). Earlier humans evolved two specialized organs—the hand and the vocal tract—as primary instruments for externalizing artificial or semantic representations. These organs and the externalized representations may have co-evolved with the Homo brain. The archaeological record yields examples of simple representations by 1.6 mya. More complex, hierarchical, and recursive forms are evident by roughly 0.25 mya. Complex and highly recursive representations in a wide range of media (including representations of representations in the form of visual art) emerge after 0.1 mya among anatomically modern humans.  相似文献

Multiple groups have interests that intersect within the field of deep submergence (beyond the 50 meter range of SCUBA) archaeology. These groups?? differing priorities present challenges for interdisciplinary collaboration, particularly as there are no established guidelines for best practices in such scenarios. Associating the term ??archaeology?? with projects directed at underwater cultural heritage that are guided by archaeologists poses a real risk to that heritage. Recognizing that the relevant professional organizations, local laws, and conventions currently have little ability to protect pieces of cultural heritage across disciplines and international boundaries, the authors propose institution-specific mechanisms, called Archaeology Review Boards, guided by local and international laws and conventions concerning cultural heritage, as the best means to provide oversight for academically centered archaeological activities at the local level.  相似文献

Demographic change has recently re-emerged as a key explanation for socio-cultural changes documented in the prehistoric archaeological record. While the majority of studies of Pleistocene demography have been conducted by geneticists, the archaeological records of the Palaeolithic should not be ignored as a source of data on past population trends. This paper forms both a comprehensive synthesis and the first critical review of current archaeological research into Palaeolithic demography. Within prevailing archaeological frameworks of dual inheritance theory and human behavioural ecology, I review the ways in which demographic change has been used as an explanatory concept within Palaeolithic archaeology. I identify and discuss three main research areas which have benefitted from a demographic approach to socio-cultural change: (1) technological stasis in the Lower Palaeolithic, (2) the Neanderthal-Homo sapiens transition in Europe and (3) the emergence of behavioural modernity. I then address the ways in which palaeodemographic methods have been applied to Palaeolithic datasets, considering both general methodological concerns and the challenges specific to this time period. Finally, I discuss the ability of ethnographic analogy to aid research into Palaeolithic demography.  相似文献

This paper discusses the history and trending of archaeological education in South Africa, a set of frameworks wherein primary and secondary level students instrumentalize archaeology to investigate and debate their pasts. Archaeological education has existed thus far as a conversation among archaeologists and a footnote in the national curriculum. I present the first cohesive treatment of these projects. I examine attendant conflicts and obstacles, drawn partly from my involvement in two South African projects but illustrating issues that I believe have global resonance. I submit that archaeological education entails engagements that hold serious ramifications for archaeological ethics, practice, and epistemology.  相似文献
