Abstract

The English botanist and gardener John Tradescant the Elder's diary from a voyage to northern Russia in 1618 has lately attracted attention as a potential source on early Russian sea mammal hunting on the Svalbard archipelago. This article examines the usefulness of Tradescant's diary in this respect, but comes to a negative conclusion.  相似文献

岩体开裂是危害花山岩画最严重的病害,会对岩画造成毁灭性的破坏。为制定有效的灌浆加固措施,在对岩体开裂成因及影响因素分析和现场调查的基础上,做了统计分析。结果表明:1)岩画区共有418处开裂病害,开裂岩体以风化开裂体为主,占69%,且构造开裂体的厚度大于风化开裂体;2)构造开裂体的钙质、钙质与泥质共同充填比例为78%,高于风化开裂体的52%;3)构造裂隙和风化裂隙的张开度均以小于6mm为主,可知当张开度大于6mm时,开裂体将发生剥离掉块;4)风化开裂体的危险性I级、Ⅱ级所占的比例为57%和22%,小于构造开裂体的64%和27%,但风化开裂体多发育于岩画存在部位,易出现开裂和掉块,破坏更大;5)构造开裂体的厚度较大、裂隙连通性好、危险等级高,而风化开裂体厚度较薄、裂隙贯通性差、危险等级较高。本研究结果可为开裂岩画岩体灌浆加固及后期修复提供理论依据。  相似文献

In Canada, research has found few differences in levels of political participation between Francophones and Anglophones despite traditional differences in resources leading to participation. This study argues that it is when gender is considered alongside language that differences emerge. Differences in conditions between Francophone and Anglophone women may mean that the explanations for the gender gaps differ. Findings show that Francophone women in Québec have lower levels of political participation than Anglophone women and men across Canada. These gender gaps are small but significant. Differences in resources and involvement in voluntary associations help account for Québec Francophone women’s lower participation. Additionally, these results indicate that the different political context and the different political influence of the women’s movement in Québec matter in determining explanations for gender gaps in political participation.  相似文献

The Danish Atomic Energy Commission (AEK) was created in 1955 with the remit to promote ‘the peaceful exploitation of atomic energy for the benefit of society.’ Between 1956 and 1963 the AEK, which had been preceded by a number of early private nuclear initiatives, established an ambitious atomic energy research facility at Risø, some 40 kilometers west of Copenhagen. For most of this period the AEK was chaired by the celebrated physicist Niels Bohr. In spite of strong support from relevant actors in Danish society and Risø’s management, Denmark never built commercial nuclear power stations. Today Risø has undergone a complete metamorphosis from atomic energy research facility to a national laboratory, doing research and development on a broad range of alternative energy sources. Using concepts and approaches like national innovation systems and technological nationalism, the present paper will explore why and how this remarkable development took place.  相似文献

The ecological tolerances of Neandertals, their ability to subsist in the dense forests of full interglacials, and their capacity to colonize northern latitudes are the subject of ongoing debate. The site of Hollerup (northern Denmark) lies at the northern extreme of the Neandertal range. Dated by various techniques to the Eemian interglacial (MIS 5e), this site has yielded the remains of several purportedly butchered fallow deer (Dama dama). Taphonomic reanalysis of the remains from Hollerup and a handful of other Eemian-aged fallow deer skeletons cast doubt on the interpretation that they were humanly modified. We place this revised conclusion into the wider context of human settlement of southern Scandinavia during the Eemian. Other claims of Neandertal presence in the region rest on candidate Middle Paleolithic artifacts, all of which derive from surface contexts. With the fallow deer material removed as a secure indicator of Neandertal settlement of Denmark during the last interglacial, this lithic material must be viewed with renewed skepticism. While ecological and/or topographic factors may have played an important role in preventing Neandertals from penetrating into peninsular Scandinavia, we caution that geological, taphonomic, research-historical, and demographic factors may have significantly distorted our picture of their occupation in this region.  相似文献

Following the 2005 terrorist attacks on London it emerged that two of the terrorists charged with the failed 21st July bombings had arrived in the UK as child asylum seekers from East Africa. In the ensuing debate the bombers were represented as children that turned to hate. In this discussion paper we draw on empirical work conducted in Sheffield, UK to explore the identities, affiliations and practices of Somali asylum seeker children, aged 11–18.1 1This ongoing research is being funded by the ESRC Identities and Social Action Programme (Award No: RES-148-025-0028) View all notes Specifically, we argue that the actions of the two bombers need to be framed within a broader understanding of the complex processes of social identification that take place as young people negotiate what it means to be a child in the context of different ‘age’, gender and racialised expectations and against a backdrop of discrimination and social exclusion in different relational geographical spaces. We begin by outlining the context of UK immigration policy, before reflecting on dominant constructions of both childhood and asylum seekers. We then discuss how these may shape young refugee and asylum seekers' own narratives of the self and the role that their mobility and specific sites of identity formation may play in this process. In doing so, we contribute to children's geographies by addressing a group – refugee and asylum seekers – that has been neglected within the sub-discipline.  相似文献

Although public participation has become an integrated part of planning practice, experience and documents literature still document difficulties in implementing participatory planning processes that provide arenas where citizens can truly influence planning. Based on a combination of institutional theory and action research methodology, this paper focuses on the institutional boundaries to introducing participatory practices by exploring openings and closures to the adoption of participatory planning processes by the Danish energy transmission system operator (TSO). Public participation in the Danish energy sector is characterized by complex institutional arrangements. The study shows how institutional boundaries are perceived by planners and how openings and closures can be identified and developed in an action research approach. The study reveals that citizen involvement has the potential to influence existing power structures but is highly challenged by an instrumentialised and sector-divided planning.  相似文献
