Mayanist archaeology has long been concerned with creating and evaluating explanatory models for the locations of ancient sites relative to one another and to the physical geography of the Maya world. This study combines epigraphic data and spatial analyses to explore motivations for settlement location and to interrogate territorial strategies in Late Classic (a.d. 600–830) kingdoms in the southern Maya Mountains, around the modern towns of Dolores and Poptún, Guatemala. Least-cost path analyses were used to model natural travel corridors and their relationship with site location was assessed. In conjunction, viewshed analyses were applied to evaluate the importance of visual connections to likely travel routes. The results are considered in the context of the socio-politics and economics of the region, and raise questions about the character of and interconnections between travel, exchange, settlement location, and mechanisms for reinforcing territorial claims in the Late Classic Southern Maya Mountains. 相似文献

James Arthur Prescott was a prominent soil scientist whose career responded to an increasingly complex, recognisably Australian web of interpenetrating spatial scales, served to promote revolutionary global advances in his chosen field, and in the process negotiated the blurred boundaries between ‘pure’ and ‘applied’ research. Encounters with this instructive life suggest that, while resolutions of pivotal anxieties might turn on ineluctably personal qualities, they also reflect a dynamic interplay between international, imperial, national and state contexts. Prescott's innovative contributions to soil science, fruits of a tenaciously consolidated career, influenced resource appraisal and environmental management across a prodigious continental expanse. A sustained focus on local and regional development brought him into contact with a wide range of contemporaries, including pioneering geographers, and culminated in his election to a Fellowship of the Royal Society. 相似文献

Few previous studies of socio‐spatial isolation have explored both its spatial and temporal dimensions. This study proposes and implemented four visual methods for analysing socio‐spatial isolation using graphic representation of people's social networks and activity patterns in space and time: 3D space‐time paths, time windows, 3D activity density surfaces, and ring‐based visualisation of social networks. These visualisations utilise both activity‐travel data and social network information. The data used were collected through a specially designed activity‐travel diary survey with a sample of Koreans in the Columbus metropolitan area in Ohio (USA). The results show that these visualisations can considerably enhance our understanding of the relationships between people's activities in space‐time and their social interactions. Combining social network analysis with activity pattern analysis can lead to a better understanding of socio‐spatial isolation. 相似文献

GIS Methods in Time-Geographic Research: Geocomputation and Geovisualization of Human Activity Patterns 总被引:12,自引:0,他引:12

Over the past 40 years or so, human activities and movements in space‐time have attracted considerable research interest in geography. One of the earliest analytical perspectives for the analysis of human activity patterns and movements in space‐time is time geography. Despite the usefulness of time geography in many areas of geographical research, there are very few studies that actually implemented its constructs as analytical methods up to the mid‐1990s. With increasing availability of geo‐referenced individual‐level data and improvement in the geo‐computational capabilities of Geographical Information Systems (GIS), it is now more feasible than ever before to operationalize and implement time‐geographic constructs. This paper discusses recent applications of GIS‐based geo‐computation and three‐dimensional (3‐D) geo‐visualization methods in time‐geographic research. The usefulness of these methods is illustrated through examples drawn from the author's recent studies. The paper attempts to show that GIS provides an effective environment for implementing time‐geographic constructs and for the future development of operational methods in time‐geographic research. 相似文献

ABSTRACTThis is a review of the 6th Postgraduate Conflict Archaeology conference held in Glasgow in October of 2019. It summarizes the presentations and keynotes delivered at the two-day conference, and reflects on the benefit of postgraduate and ECR specific conferences, the gender disparity within the field of conflict archaeology, and the importance of a supportive network of colleagues. 相似文献

Work intensification is a characteristic of the current neoliberal trend in academia. Postgraduates and Early Career Researchers (PhD candidates and ECRs) in geography are no strangers to this development but are rarely the focus of publications or dialogue on the (gendered) outcomes of the academy’s neoliberal agenda. Encouraged by the recent emotional turn in the social sciences and humanities, this article seeks to unveil some of the everyday particulars of life in academia for PhD candidates and ECRs under the tide of financial cuts and increased competition for funding. We explore the question: “Who can – and indeed wants to – play this game?” As three early and one mid-career academic women in four different institutions in the Global North, we make use of reflexivity, autobiographical writing, and reflection, to analyze increasingly stressful and demanding working conditions. Through the depiction of our lived experiences, we contend that the push for ever increasing outputs attends most of our time and represents a distinctly different form of scholarship than has been traditionally considered as the pathway into academia, not seldom jeopardizing well-being of young academics, one that needs to be interrogated by geographers. 相似文献

ABSTRACT Attention to history is widely seen as a necessary corrective to the synchronic perspective of ethnography, especially as this has come to inform research in Melanesia. In fact, anthropologists turn to the study of history not only to understand ‘change’ and ‘the past’ but to delineate the ‘history’ of the people studied. However, history as a concept and discipline has a unique place in western knowledge conventions, an outcome of the distinctive ways of gauging and relating past, present and future. Historical analysis can augment ethnography but not necessarily portray the history of the people concerned, as they may have no history, as such. The article suggests that historicity is a more appropriate notion with which to register the significant ways in which the social past is entangled in what people are and do and in their future potentialities. This argument is made with reference to the Fuyuge people of highland Papua and their involvement in engineered trail and road building during the colonial and post‐colonial period and their simultaneous interest in the performance of their gab ritual. These events exemplify different kinds of power and associated historicity. Through scrutiny of each it is shown that the form of Fuyuge (Melanesian) historicity parallels that of their sociality and its distinct temporality. The events that actors perform produce not so much history, as the recurrent evocation of past actions and the foreshadowing of future ones. 相似文献
