In technological approaches to prehistoric industries, there is currently a renewed interest in the transformation of osseous materials. This approach requires the construction of a technical reference base of manufacturing stigmata, as well as of the procedures and methods used to produce tool blanks.One of the better known processes for the production of blanks in the Upper Palaeolithic is extraction by a double longitudinal groove, observed only in the Gravettian. Aurignacian artefacts indicate that during this period blanks were obtained through a procedure of longitudinal fracturing (splitting) or diffuse percussion fracturing. The manner of implementing these procedures is, however, still poorly known.In order to better characterise this stage in the manufacturing of blanks for antler points, we conducted an experimental study. Based on a thorough analysis of the Spanish archaeological materials, we tested the procedure of fracturing by indirect percussion on deer antler. The results provide new criteria for the identification of blanks and their manufacturing processes. They also emphasize the possibility of predetermining the size of the blank and, consequently, the size of future projectile point.  相似文献

The creative class thesis put forward by Florida [(2002a) The Rise of the Creative Class and How it's transforming Work, Leisure, Community and Everyday Life (New York: Basic Books)] has in recent years been subject to vivid debate and criticism. This article applies the creative class thesis onto a Nordic context in order to examine whether Florida's theory proves fruitful in a context different from the US. Based on qualitative data, the paper analyses the role of people climate and business climate for the location of the creative class and firms in three different kinds of regions in four Nordic countries. The analyses demonstrate that the people climate tends to be of secondary importance to the business climate in explaining the location of the Nordic creative class. This should be seen as a result of the urban hierarchy within the Nordic countries as well as a strong welfare policy, which ensures an equal distribution of public provision and supports dual career households. Together, these factors diminish the role of people climate for location choices. The study also finds that the notion of people climate has different meanings in various places, and what attracts or repels the creative class depends on the life phases of the members of the creative class. The study raises concerns about the potential for applying the creative class approach beyond large city regions, which limits its usability in regional planning.  相似文献

Geography and the medical‐health sciences have long histories of engaging the humanities. The last decade has seen for both disciplines a significant growth in theoretical frameworks, pedagogic strategies, and research methods that draw upon visual and literary arts, critical self‐reflection, creative tools and expressions, and even direct engagement or partnership with artists, curators, authors, theatre‐practitioners, and other professionals in the arts. Both geographers and medical‐health professionals, then, are increasingly (re)making and understanding various worlds through the humanities. In this paper we explore the histories of humanities in both geography and the medical‐health sciences, especially medicine: we argue the two disciplines have much to learn from each other's engagement and work with the humanities. Focusing on the increasing use of narrative and storytelling in both disciplines, we argue that deployment of humanities‐based frameworks and impulses must not be taken up without careful and critical analytical reflection. Finally, we ground our theoretical explorations with empirical examples from recent community‐based work about the risks and benefits of storytelling and visual arts when looking at the health geographies of Indigenous and settler peoples in Northern British Columbia.

De manière impromptue : vers une démarche critique sur les méthodes de mise en récit et les méthodologies en géographie et en sciences médicales et de la santé

L'intérêt pour les sciences humaines par la géographie et les sciences médicales et de la santé s'inscrit dans une longue tradition. Au cours de la dernière décennie, les deux disciplines ont connu une importante croissance de cadres théoriques, de stratégies pédagogiques et de méthodes de recherche qui font appel aux arts visuels et à la littérature, à l'autoréflexion critique, à des outils et modes d'expression novateurs, voire même à une participation directe ou à des partenariats avec des artistes, conservateurs, auteurs, praticiens de l'art dramatique et d'autres professionnels du domaine des arts. Autant les géographes que les professionnels de la médecine et de la santé contribuent de plus en plus à (re)constituer et comprendre divers mondes à travers les sciences humaines. Cet article brosse un tableau historique des sciences humaines tant en géographie qu'en sciences médicales et de la santé, en particulier la médecine : nous soutenons que les deux disciplines ont beaucoup à apprendre l'une de l'autre sur l'intérêt que chacune porte aux sciences humaines. En mettant l'accent sur le recours grandissant par les deux disciplines à la narration et à la mise en récit, nous faisons valoir l'idée que le déploiement des cadres et des impulsions fondés sur les sciences humaines ne peut pas être envisagé sans mener au préalable une réflexion analytique minutieuse et critique. Enfin, nous fondons cette étude du champ théorique sur des exemples empiriques tirés de travaux réalisés à l'échelle communautaire sur les risques et les avantages de la mise en récit et des arts visuels quand on se penche sur les aspects géographiques de la santé des peuples autochtones et colonisateurs dans le nord de la Colombie‐Britannique.  相似文献

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

Visible homelessness in the Northwest Territories, Canada is often described as a recent phenomenon by policy makers and the popular media alike. Indeed, since the late 1990s, homeless shelters in Yellowknife and Inuvik report a steady increase in demand for beds and other support for homeless people. Homelessness in these two communities disproportionately affects Aboriginal northerners, however little is known about their individual pathways to homelessness. Moreover, homelessness in the Northwest Territories is often portrayed as an issue confined to larger “urbanizing” regional centres, yet many homeless Aboriginal northerners have originated from small, rural settlement communities. Despite this, little concern has been paid to how factors at the small community level intersect with more visible forms of homelessness in larger, urban centres, not to mention how these intersections shape a territorial geography of homelessness. In this article, I aim to uncover and explore the often hidden factors at the northern rural settlement level that ultimately contribute to more visible forms of homelessness in northern urban centres. I suggest that uneven and fragmented social, institutional, and economic geographies result in a unique landscape of vulnerability to homelessness in the Northwest Territories. This geography emerges through the production of particular dynamics between rural settlement communities and northern urban centres. In particular, four main factors represent these rural‐urban dynamics: 1) the attractions of opportunity in northern urban centres; 2) rural settlement‐urban institutional flows; 3) chronic housing need in the settlements; and, 4) disintegrating social relationships in the settlements. I explore the particular ways in which these factors influence rural‐urban migration among the homeless population and what roles this mobility plays in individual pathways to homelessness.  相似文献

A growing number of geographers seek to communicate their research to audiences beyond the academy. Community‐based and participatory action research models have been developed, in part, with this goal in mind. Yet despite many promising developments in the way research is conducted and disseminated, researchers continue to seek methods to better reflect the “culture and context” of the communities with whom they work. During my doctoral research on homelessness in the Northwest Territories, I encountered a significant disconnect between the emotive, personal narratives of homelessness that I was collecting and more conventional approaches to research dissemination. In search of a method of dissemination to engage more meaningfully with research collaborators as well as the broader public, I turned to my creative writing work. In this article, I draw from “The komatik lesson” to discuss my first effort at research storytelling. I suggest that research storytelling is particularly well suited to community‐based participatory research, as we explore methods to present findings in ways that are more culturally appropriate to the communities in which the research takes place. This is especially so in collaborative research with Indigenous communities, where storytelling and knowledge sharing are often one and the same. However, I also discuss the ways in which combining my creative writing interests with my doctoral research has been an uneasy fit, forcing me to question how to tell a good story while giving due diligence to the role that academic research has played in its development. Drawing on the outcomes and challenges I encountered, I offer an understanding of what research storytelling is, and how it might be used to advance community‐based participatory research with Indigenous communities.  相似文献
