不同于精英阶层获取知识的正式教育模式,以非正规群体为代表的社会基层群体更多依靠非正式教育渠道实现知识技能的学习。本文将广州电视塔周边的非正规旅游摄影经营者作为研究对象,在个体访谈和非参与式观察的基础上采用质性研究方法探究其知识技能学习与管理的过程。研究发现非正规旅游经营群体的知识学习表现出明显的集体行为特征,知识在群体组织网络中高度依靠关系导向实现流动共享,并且在群体内部形成了“核心-次核心-边缘”的等级体系,知识的流动又被作为维护等级权威的规训管理手段反作用于群体组织。此外,群体通过知识技能的标准化来增强集体的共享互惠效果,形成非正规旅游经营群体“自下而上”的群体学习与知识流动的有力保障。  相似文献

ABSTRACT

Reports of patrols through remote areas of Papua and New Guinea led by officers of the Australian administration have much to contribute to understandings of the work entailed in rendering both land and people legible to the colonial state. But these must be read with care. Using the text and maps produced by one patrol, led by John McGregor in 1968, we demonstrate how topographic maps, produced well after particular patrols were undertaken, may be used to both refine interpretations provided in such reports and reveal factors that shaped the knowledge patrol officers produced.  相似文献

This paper examines “moments of residents' awareness” and their ethics in three planning processes, each representing different relations between local and professional knowledge in the course of the three‐year regeneration project in Meonot Yam neighborhood, Bat Yam, Israel. This new terminology emphasizes how nuanced relations between various types of knowledge better explain the challenges faced by planners and residents in regeneration projects. These moments reflect residents' empowerment, challenging the binary view of professional/powerful versus local/ powerless knowledge that characterizes modernist thinking. The paper proposes that in such complicated processes it helps to analyze moments of power/knowledge transformation, from which one can learn that conflict and disagreement, and not only consensus, can lead to residents' empowerment.  相似文献

Theorizing within the umbrella of evolutionary economic geography (EEG) has improved the understanding of how inter‐firm relatedness conditions knowledge spillovers, and how this affects the long‐term evolution of regions. Still, there are shortcomings in this approach associated with a quantitative and generic methodology, a static notion of relatedness, and a weakly developed policy and institutional perspective. In particular, there is a need for a better understanding of the mechanisms through which relatedness is developed and how policy affects existing and emerging relatedness. Certain mechanisms for knowledge transfer have been suggested, such as labour mobility, firm diversification, spin‐offs and social networks. But do the same mechanisms apply to all industries and in all territories, or are there specific mechanisms of knowledge sourcing at work in different contexts? To shed light on these questions, the article reports on a comparative case study of two knowledge‐intensive industries (life science and publishing) located in the Oslo metropolitan region. Based on a case study, the article suggests that both industries source knowledge through similar types of channels. However, despite similarities in how knowledge is accessed and absorbed in this diverse urban context, knowledge sourcing also seems to be conditioned by industry‐specific dynamics, policies and institutions.  相似文献

为研究云冈石窟顶部土壤覆盖层的含水率变化情况,建设了土壤环境监测网收集云冈石窟土壤含水率实时监测数据,并分析其时空变化特征及影响因素。结果表明,平坦地形条件下云冈石窟顶部第四纪土壤覆盖层含水率时空变化特征明显:年变化具有周期性,垂向上随深度逐层降低(冬季除外)。春、夏季土壤含水率抬升、储水,秋、冬季下降、失水;在春、夏日土壤含水率呈白天上升、夜晚下降趋势,秋、冬日则呈白天下降、夜晚也下降趋势。土壤含水率时刻处于不停的运动变化之中,受温度、大气降水、微地形等众多因素影响,山体边坡浅层土壤可能为侧向饱和流的入渗通道。降雨对土壤含水率的影响深度与实际入渗深度不一致。云冈窟内顶板及岩壁上部、中部含水率主要受降雨渗透窟顶土壤层、沿岩体裂隙通道进入洞窟的渗漏水控制,而岩壁底部含水率更多受窟前不饱带和与地下毛细水的影响。多年的防水实践也证明云冈洞窟渗漏水主要来自于石窟顶部及附近区域。防渗排水始终是云冈洞窟渗漏水治理的主导思路,建议应根据窟顶土壤厚度、地形地貌和遗址分布等分区治理,充分发挥土壤的防渗作用,减少对土壤覆盖层的过度干预。防渗层材料在具有防渗作用的前提下,应具备一定的透气性,满足“洞窟—覆盖层—大气环境”之间的水汽循环。  相似文献

ABSTRACT

This article explores two ideas due to Alan Wilson: superconcepts and enabling disciplines. These ideas emerge from Wilson’s philosophy of knowledge and, in particular, from his thinking on interdisciplinarity. Both ideas are described, analysed and developed in the context of their wider importance in interdisciplinary undergraduate education and their implementation on the Arts and Sciences BASc at UCL. Some suggestions for future developments of these ideas at the proposed new university at the London Interdisciplinary School are offered.  相似文献

This article argues that understanding how people classify physical geographic features is necessary for identifying fundamental, cross‐cultural geographic concepts that are required for successful communication of geographic knowledge. Academic geographers have not given sufficient attention to systems of local geographic knowledge, even though promising theoretical frameworks exist, particularly in the field of ethnoecology. However, the research approach that has characterized ethnoecology is insufficient to develop ethnogeography as a field of inquiry, because ethnoecologists have overemphasized limited aspects of local knowledge systems, such as soils, which has often led researchers to incompletely sample local knowledge systems. Using ethnographic methods, this article analyses the content and structure of physical geographic knowledge in the Maninka language as spoken in southwestern Mali, and compares Maninka knowledge to that of other cultural groups. The results suggest that broad physical geographic concepts may be shared pan‐environmentally, but that most physical geographic knowledge is contained in culturally specific classifications embedded within a broad cross‐cultural framework. Academic geographers should expect only broad correspondence between their categories of physical geographic variation and those of people who classify biophysical features according to local knowledge systems. Finally, this article also shows that ethnoecological research will be advanced if geographic theories of place are given more prominence in ethnoecological studies.  相似文献

In this article I experiment with emotional and relational approaches to further understand the ways that masculine privilege operates in the academy. In doing so, I build on longstanding feminist geographical discussions of masculine knowledge. I argue that emotional and relational more-than-human approaches to examining knowledge offer valuable opportunities to explore the ways that masculine privilege operates through the discipline and lay bare normative Enlightenment (humanist, Cartesian, masculine, Eurocentric) constructions that shape current hegemonic knowledge systems.  相似文献

This article discusses Karsten Heuer’s 2006 book Being Caribou in light of debates in ecocriticism and border studies about how to define the local in the context of environmental problems of vast range and uncertain temporality. It explores how Heuer’s book about following the Porcupine Caribou herd’s migration engages in multiple forms of boundary crossing—between countries, between hemispheric locations, and between species—and shows how insights from Indigenous storytelling complicate the book’s appeal to environmentalist readers by asserting a prior, transnational Indigenous presence in the transboundary landscapes of present-day Alaska and the Yukon.  相似文献
