This article examines how the practice of learning geography, and the arenas in which knowledge-making takes place, can be usefully positioned within changing histories of the discipline. It contends that networks of action – understood through the intersection of social sites, subjects and sources – present a conceptual framework and narrative focus for the re-consideration of specific episodes from geography's past. The interventions made here are informed and illustrated by a 'small story' about the doing of geography. Based on different personal accounts, the story revives a series of events, encounters, dialogues and images dating back to the winter of 1951 at Glenmore Lodge, Scotland. This educational institution in the Cairngorm mountains offered children from urban areas the opportunity to learn field studies and the skills of 'outdoor citizenship'. Initially, the focus falls on Margaret Jack, a 14-year-old field-course participant. Her learning experiences are traced through personal letters, a diary and a field journal dating from that time, and her recent recollections of this event. Margaret's account dovetails with the story of her field studies instructor, Robin Murray. Robin's role is traced through his learning experiences as a geography undergraduate at Aberdeen University, and the recent recollections of Catriona Murray, his wife.  相似文献

River meander behaviour and instability: a framework for analysis   总被引:2,自引:0,他引:2  
Recent empirical and theoretical work on river meanders suggests that instability is inherent. Within this context, an occurrence of multiple cut-offs could be interpreted as a clustering associated with self-organized criticality. Types of meander behaviour ranging from stable to chaotic are examined as trajectories or attractors within the phase space of rate of meander movement and bend curvature and change to the system is explored as shift from one attractor to another. It is suggested that this new approach provides insights into meander dynamics and provides a basis to identify the conditions, limits and constraints under which different behaviour occurs. Basic controls of energy and resistance underlie planform behaviour, but need to be refined in relation to the morphology and stability of channel courses.  相似文献

This paper explores the spatialities constructed through resistances to globalization. It focuses on the Inter-Continental Caravan, an ambitious project which united activists from the Indian New Farmers Movements with West European green activists in contesting neo-liberal institutions and biotechnology. The paper argues that these political activities constructed distinctive 'maps of grievance'. This term is used to suggest that the construction of grievances has both a distinctive spatiality and is constitutive of political identities. The paper argues that the different maps of grievances generated through the project were both a condition of possibility for these transnational alliances and exerted pressure on the formation of solidarities. It concludes by arguing that the location of counter-globalization politics at the intersection of different routes of resistance can be integral to the formation of alternative political imaginaries.  相似文献

This paper contributes to a rethinking of the ethical sensibilities of geographical research in the context of an emerging interest amongst geographers in non-representational registers of thinking and moving. Rather than undermining geographical engagements with questions of the ethical, the paper argues that this emerging interest in questions of the non-representational actually extends the range and repertoire of empirical contexts and conceptual vehicles within and with which such an engagement can take place. The paper argues that attending to and through the relation between affect and ethics is particularly important to this effort. The importance of affect in this regard is illustrated through a series of examples drawn from an 18-month participatory encounter with a specific therapeutic practice, Dance Movement Therapy. Drawing upon such examples, the paper offers some lines of ethical potential that might provide orientation to further geographical research. In doing this, the paper concentrates in particular on the necessity of cultivating a fidelity to the affective event of geographical ethics as much as remaining faithful to the subject or object of an ethical code.  相似文献

This paper provides a comprehensive analysis of the pattern of hospital utilization (rather than provision) in England prior to the establishment of the NHS, showing the extent to which the probability of obtaining hospital treatment was a function of residence. Access to hospital care depended on the vigour of voluntarism and the political priorities of local governments. The pattern of voluntary hospital utilization is shown to have been markedly unequal, but the effect of municipal provision was to reduce disparities in access to services. The paper demonstrates variations in hospital utilization and discusses contemporary assessments of the situation. This work contributes to debates about the efficacy of non-profit forms of welfare delivery; it provides a novel British study to complement American work in this field. It also raises questions about the contemporary vogue for partnerships in health care delivery between the public and private sectors, arguing that such proposals rest on an optimistic view of history.  相似文献

Ancient Maya settlement patterns exhibit fractal geometry both within communities and across regions. Fractals are self-similar sets of fractional dimension. In this paper, we show how Maya settlement patterns are logically and statistically self-similar. We demonstrate how to measure the fractal dimensions (or Hausdorff–Besicovitch dimensions) of several data sets. We describe nonlinear dynamical processes, such as chaotic and self-organized critical systems, that generate fractal patterns. As an illustration, we show that the fractal dimensions calculated for some Maya settlement patterns are similar to those produced by warfare, supporting recent claims that warfare is a significant factor in Maya settlement patterning.  相似文献

This paper reviews archaeological applications of optimization theory applied to resource use. A model of agricultural corn production is derived for a single Muscogee Creek Indian town (CA 1725–1825) which was situated in the southeastern United States. The corn productivity model is based on soil depletion, soil variation, known locations of horticultural fields, population size, and nutritional requirements. The corn productivity model shows that corn production varied significantly between 1725 and 1825. The residents of the town shifted their horticultural gardens in order to maintain a nutritional minimum. The model was compared to the marginal value theorem and expectations derived from risk minimization models. Residents of Cussetuh abandoned their horticultural fields well before the instantaneous long-term average rate of production for the habitat. The model shows that the residents of Cussetuh were risk minimizers and were not maximizing the long term average rate of corn yield in their gardens.  相似文献

避暑山庄初建时间及相关史事考   总被引:2,自引:0,他引:2  
避暑山庄初称热河行宫。其始建时间在清代官修史籍中无载,私家笔记和现代学者其说不一,似无从定论。本文在参阅史籍和清宫遗档的基础上,认为热河行宫肇建于康熙四十二年七月二十三日(1703年9月4日),并对其始建时期的相关史事作出考定。  相似文献

西周至南北自制玻璃概述   总被引:2,自引:0,他引:2  
我国玻璃起步较晚,大体始于西周初或先周(殷末),主要是蓝色、浅蓝色或绿色玻璃珠管,与玉、玛瑙配合制成“杂佩”。其时玻璃的主要成分为二氧化硅,并含有少量铅、钡,故称为铅钡玻璃,与西方钠钙玻璃不同而独树一帜。春秋战国时期,西方蜻蜓眼玻璃珠输入我国,从此,以仿羊脂白玉美若明月的“隋侯珠”为代表的自制玻璃与外来玻璃并存。西方(大月氏)吹制玻璃术于汉魏传入我国之后,也出现了自制的空心玻璃器皿。  相似文献

在绘画创作中,李流芳的山水画在晚明画坛颇具代表性,其山水画在空间处理上已呈平面化趋势,树木山石的画法也具有某种符号化的特征,这种为追求形式之美而舍弃写实的描绘与明末形式主义画家有共同之处。  相似文献
