In an era of rapid geographical data acquisition, interpretations of remote sensing products are an integral part of many undergraduate geography degree schemes but there are fewer opportunities for collection and processing of primary remote sensing data. Unmanned Aerial Vehicles (UAVs) provide a relatively inexpensive opportunity to introduce the principles and practice of airborne remote sensing into field courses, enabling students to learn about image acquisition, data processing and interpretation of derived products. Two case studies illustrate how a low-cost “DJI Phantom Vision+” UAV can be used by students to acquire images that can be processed using Structure-from-Motion photogrammetry software. Results from a student questionnaire and analysis of assessed student reports showed that using UAVs enhanced student engagement and equipped them with data processing skills. The derivation of bespoke orthophotos and Digital Elevation Models has the potential to provide students with opportunities to gain insight into various remote sensing data quality issues, although additional training is required to maximize this potential. Recognition of the successes and limitations of this teaching intervention provides scope for improving future UAV exercises. UAVs are enabling both a reconstruction of how we measure the Earth’s surface and a reconstruction of how students do fieldwork.  相似文献

The study of diaspora policies in political science, international relations, and political geography has moved away from conceiving diasporas as bounded entities to conceptualizing diasporas as a process to be made. One body of literature maps different strategies employed to bond diasporas to their country of origin, while another body of literature pays specific attention to diasporic identities and the ways such identities are reproduced and constructed abroad. This article seeks to bring these two literatures together by focusing on homeland tourism as a diasporization strategy, i.e. the construction, reproduction, and transmission of diasporic identity. Through the case of Taglit-Birthright – a free educational trip to Israel offered to young Jewish adults – the article identifies the specific mechanisms and micro-practices used in order to transform Israeli territory into a Jewish homeland, reproduce the narrative of dispersion, and demarcate group boundaries. Incorporating insights from theories of territorialization and based on the program's educational platform and existing ethnographies of Taglit-Birthright, this article unpacks the notion of the homeland and demonstrates how the homeland itself – as an embodied, affective, and symbolic site – is strategically used in order to cultivate diasporic attachments.  相似文献

At the turn of the twentieth century, the Brazilian Amazon was experiencing a moment of heightened exploration, mapping, border creation, and contestation. This article examines the production of the French explorateur and geographer Octavie Coudreau through analysis of the natural history/travel narrative, Voyage au Trombetas (1899), and her subsequent narrative Voyage au Cuminá (1901). Octavie Coudreau initially went to Amazonia to travel with her husband, Henri Coudreau, already a renowned explorer of the French and Brazilian Amazon. After Henri Coudreau’s death on their first voyage, Octavie Coudreau continued working under contract for the Brazilian state and published natural history narratives after each of her four exploratory and mapping missions. These travel narratives include suggestions for increased colonization along with observation of local populaces, supported by a multitude of maps and photographs. Using feminist approaches to the historiography of travel, empire, and geographical work, I look at the female European explorer’s view of imperialism during this significant period in Amazonian history and development. I examine the unfixing of gender identity as it relates to movement within a liminal space. I think of this as the in-between place in which Octavie finds herself – as a grieving widow, thrust into a position of power abroad, while still dealing with the limitations of her gender during this time period, and the space of the Amazon itself, a region in flux where multiple races and imperial powers interact in a contact zone.  相似文献

Recent feminist geographic scholarship insists we rethink domestic violence as ‘intimate war’. Using this concept I analyze narratives of violence and resistance articulated by U.S.-resettled South Sudanese women and collected in the wake of a fatal incidence of domestic violence in 2005. One of a spate of intimate partner murders that shook the community at this time, this tragic event spurred debates about shifting gender norms, the stresses and opportunities of life in the diaspora, and the irradicable legacies of war. Bringing Pain and Staeheli's ‘intimacy-geopolitics’ to bear on this particularly violent, momentary and publicized aggression, I situate it within a more complex, quotidian, and dynamic terrain of power. In line with feminist political geography, this analysis complicates scalar distinctions of body, home and nation-state, demonstrating the common foundations of ‘private’, domestic and ‘public’, state-sanctioned violences. Inspired by Katz’s countertopographical approach, I extend our understanding of intimate war by contouring moments of violence and resistance in a diasporic context, over the lifecourse of refugee women, and across their sites of flight, displacement and resettlement. Tracing the mobilities of intimate war in this way productively reveals the spatial and temporal, as well as scalar, folds that may form part of its foundation.  相似文献

Ivan Jablonka seeks something other than a mere combination of history, social science, and literature. He would like history, itself understood as a social science, to be a literature of the real world. He is also interested in literature informed not only by the results but, more important, by the forms of reasoning and inquiry of history and related social sciences (notably anthropology and sociology). Jablonka's own positioning within the Annales seems obvious, notably in his stress on cognition, problem‐oriented research, and the status of history as a social science. But the attention and research devoted in the work of scholars in and around the Annales to the relations among history, literature, and fiction have not been pronounced, and in this context Jablonka inflects the understanding of history in relatively underdeveloped directions. Despite possible disagreements one may have over specific issues, Jablonka's thought‐provoking book raises very important questions, opens many significant avenues of inquiry, and seeks a desirable interaction between historical and literary approaches.  相似文献

Brutalism is an architectural form that is experiencing somewhat of a revival of late. This revival focuses almost purely on its aesthetics, but there is an ethical dimension to Brutalism that often gets overlooked in these narratives. This paper therefore reanalyses the original concepts and ethics of brutalist architecture with a reaffirmation of the original triumvirate of brutalist ethics as articulated by Raynar Banham as monumentality, structural honesty and materials “as found”. The paper then articulates these through the literature on architectural affect to argue that brutalist ethics are continually “enacted” via a relational monumentality that brings the building and its inhabitants together in the practice of inhabitation. Using the case study of Robin Hood Gardens in London, the paper posits that a “brutalist politics” comes into light that can help catalyse a broader critique of contemporary neoliberalism.  相似文献

Abstract:

This paper is concerned with the cultural politics of agency, and explores the relationship between cultural form, migrant experience and social change. It traces the emergence of a range of literary forms in south China and how these new cultural forms provide hitherto unavailable space to contest the state- and market-driven narratives, which tend to link dagongmei’s (rural migrant women’s) sexuality with inexperience and vulnerability on the one hand, and criminality, immorality and incivility on the other. The paper suggests that these newly emerging cultural forms present alternative perspectives on the practical circumstances, moral rationalities and emotional consequences that condition and shape migrant women’s sexual experience, and for this reason, they constitute important points of intervention.  相似文献

Majority World working children's voices have attained some prominence in debates over their well-being. Many have defended their right to work, challenging Minority World understandings of children's ‘best’ interests. Yet employers' voices remain sidelined, raising questions over the extent to which the discursive and material spaces of children's work have been decolonised. A postcolonial perspective on children's work challenges suggestions that Majority World adults (and societies) need western guidance on how children ought to be raised. It also creates opportunities to look beyond western discourses of economic exploitation, to the potential for more-than-economic relationships between working children and their employers.  相似文献
