River meander behaviour and instability: a framework for analysis

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.     

An event of geographical ethics in spaces of affect

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.     

The fractal geometry of ancient Maya settlement

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.     

Dynamic optimization of horticulture among the Muscogee Creek Indians of the southeastern United States

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.

From 'industrial districts' to 'knowledge clusters': a model of knowledge dissemination and competitive advantage in industrial agglomerations

This paper integrates knowledge-based theories of the firm withgeograph-ical studies of industrial agglomeration to producea model that helps explain the competitive advantages enjoyedby proximate firms located in geographical clusters. We proposea hierarchy of specialized knowledge stocks at both firm andcluster levels and suggest that the comparative advantage conferredby knowledge resources at each level is protected, in part,by asymmetries in knowledge flows from level to level. The paperargues that codified component knowledge is more easily spreadthan firm-specific architectural knowledge. Nevertheless, overtime, agglomerations may develop a cluster-specific form ofarchitectural knowledge that facilitates the rapid disseminationof knowledge throughout the cluster by increasing the learningcapacity of proximate firms and thereby conferring cluster-specificcompetitive advantages.     

The tyranny of gendered spaces – reflections from beyond the gender dichotomy

This article argues critically that the consequences of a binary system of gender norms is experienced as a kind of gender tyranny both for those who transgress gender in their daily lives, but also for those whose lives are lived within such constraints. Feminist geographers and urban theorists have argued that space is gendered and that gendering has profound consequences for women. This article extends this analysis and shows how rigid categorizations of gender fail to include the intersexed and transgendered populations, a small and highly marginalized segment of the wider population. This article uses autoethnographic methods to illustrate the ways that those who transgress gender norms experience a tyranny of gender that shapes nearly every aspect of their public and private lives. The nature of these consequences is explored using citations from the transgender and queer literature as well as the lived experience of this tyranny by the author in a continuum of public to private spaces, including: parking lots, public restrooms, shopping malls, the workplace and the home.     

海归的适应策略研究：学院派的案例分析

文章在对部分海归”学院派”深入访谈和个案分析的基础上,运用布迪厄“文化资本理论”、“习性”和“场域”的分析工具,解析了海归“学院派”归国后的不同心态和不同适应策略的选择。得出结论,“文化资本”本身并不足以成为个体适应策略选择的决定因素,“习性”和“场域”概念也是影响个体适应策略选择的因素之一;深层文化认同的非同一性、生活表象与意识深层的非和谐性等复杂的文化意识构成他们独特的行为表象。这些行为表象是其长期海外生活学习所形成的个人“习性”的体现。透过这些表象了解他们的“习性”及其产生的原因,是深入了解他们归国后所选择适应策略的基础。     

中国村镇主体空间行为博弈及对策分析

我国进入快速城市化发展时期以来,在城市化和工业化的推动下,各类村镇主体的空间行为能力逐步增强,在其追求自身利益最大化的过程中,往往出现不理性的空间行为,在农村地区引发出诸多的空间问题。本文以各类村镇主体(农村居民、企业、农村基层自治组织、地方政府)的空间行为为研究对象,运用博弈理论深入分析各类不良空间行为产生的根源,有针对性地提出相关公共政策建议,以期改变其博弈规则,从而有效引导和规范各类村镇主体的空间行为,优化村镇空间。     

身体视角下的旅游体验——基于徒步游记与访谈的扎根理论分析

身体理论的发展为旅游体验本质的探究提供了新的可能,国内外的研究开始关注人的某些感官体验,但作为一个整体的身体还极少得到审视。在梳理相关文献的基础上,采用身体地理学视角,对收集的徒步旅行游记和访谈进行扎根理论分析,提炼出24个范畴、7个主范畴和1个核心范畴,据此建立旅游体验本质模型。结果表明,徒步旅游体验本质上是一种具身化生成实践,即旅游者通过具体身体的参与,与旅游情境深度融合,寻求个体完善与成长的对象性活动。具体包括身体意识的唤醒、身心的浸入、与他人和自然的共在以及个体的生成等四种体验类型。这些体验主要通过旅游者由身体痛苦到精神快乐的逆向选择、具有仪式象征意义的行为表演和面向自我的反思性观照三种典型路径达到。在此过程中,作为整体的身体解除了规训和压制,展现出生动鲜活的样貌,迈向持续的生成之域。
