传统工艺产业规模演变及空间演化机理——以河南省禹州神垕镇钧瓷产业为例

传统工艺产业规模演变与空间演化机制探析是保护和传承的重要前提。以河南省禹州神垕镇钧瓷产业自唐代以来的发展历程为对象,引入路径依赖与蝴蝶效应理论,构建解释传统工艺产业规模演变的分析框架。研究结果表明:偶发事件所引致的蝴蝶效应比技术进步对其规模演进影响更大,进而形成的路径依赖多是非效率选择的,空间演变的主要动力是政策安排和技术进步。正式制度安排对其技术进步与集群形成有重要推动作用,但应注意其影响的两面性,减少对"地方性"特征的冲击。     

昆明市东川城区后山泥石流灾害修复措施

东川城区后山构造发育、地震频繁、山体失稳、地形高差悬殊和雨量集中且暴雨强度大等，是导致本区泥石流频繁而猛烈的根本原因。人类不合理的经济活动则对本区泥石流的发生发展起着重要的加剧、恶化作用。对东川城区后山泥石流的治理必须采用软件和硬件两大措施相结合的综合治理办法，并对治理过的泥石流沟加强管理力度。     

The murky waters of the second wave of neoliberalism: corporatization as a service delivery model in Cape Town

This article reviews how the process of corporatization transforms public sector management by adopting private sector principles. It argues that corporatization, as an institutional form emerging from a second wave of neoliberalism, threatens to undermine the democratic accountability of local authorities by virtue of restructuring the state in ways that are invisible to the public yet with highly negative outcomes for low-income communities. The article provides a case study on the water sector in Cape Town, South Africa by tracing the local authority's adoption of three cost-recovery policies and their impacts on low-income households over a five year period (1997-2001). Engineers are the key agents in the promotion of cost-recovery policies in the efforts to deliver services more `efficiently'. While these officials are highly skilled professionals in dealing with the technical side of the production process, they lack the social training necessary to deal with the politics of distribution. The prominence of the neoliberal agenda in urban management can be in part be attributed to the power of the technical over the political as engineers displace politicians in the deliberations over how to deliver services to poor areas of the city.     

滑坡稳定性三维数值模拟分析

滑坡作为地壳表层的三维地质体,应最大程度逼近实际边界条件评价其稳定状态,同时,由于滑坡不同部位结构构造存在差异,应用不同的稳定系数评价其不同部位的稳定状态。在滑坡稳定性分析方法研究现状对比分析的基础上,介绍一种简易实用而精确度又较高的滑坡稳定性三维数值模拟分析方法,正是为达到此目标的一种探索,分析结果与已有研究成果基本一致,证明这种分析方法具有一定的可信性和优越性。     

Mapping narratives of urban resilience in the global south

In the context of global environmental change much hope is placed in the ability of resilience thinking to help address environment-related risks. Numerous initiatives aim at incorporating resilience into urban planning practices. The purpose of this paper is to open up a conversation on urban resilience by unpacking how diverse science methods contribute to the production of different narratives of urban resilience mobilizing different experts and forms of evidence. A number of scholars have cautioned against uncritical approaches to resilience and asked what resilience means and for whom, also pointing out the normative dimension of the concept. Building on this emerging scholarship we use insights from science and technology studies (STS) and critical social sciences to look at the knowledge infrastructures and networks of actors involved in the development of resilience strategies. Drawing on fieldwork in Manila, Nairobi, and Cape Town, we map different narratives of urban resilience identifying the ways in which science serves to legitimate or alienate particular perspectives on what should be done. We discuss the multiple roles that science methods have for resilience planning. Whereas urban resilience is often portrayed as consensual, we show that a range of narratives, with diverse socio-material implications, exist at the city level. In this way we unearth the conflict that lies beneath an apparent consensus for resilience policy and outline future research directions for urban sustainability.     

豫西太平镇轻稀土矿床矿化特征及矿床成因

豫西太平镇稀土矿床是新发现的中型轻稀土矿床。3条稀土矿脉共圈定4个矿体。矿体平均厚度1.77 m,平均品位ω(∑REO)为2.23%,初步估算资源量达10万t。稀土矿体严格受北西向断裂构造控制,赋存于太平镇—板山坪背斜北翼的中元古代斜长花岗岩和二郎坪群中。∑LREO占83.23%~99.35%,∑HREO占16.77%~0.65%,CeO_2+La_2O_3+Nd_2O_3在总量中分配比为79.56%~94.15%。稀土矿物以氟碳铈矿为主,矿石中主要稀土矿物的REE配分属CeLaNd富LREE强选择配分型。矿石稀土轻稀土富集,重稀土亏损,轻重稀土分馏明显,LREO/HREO比值大,铕为弱的正异常,不明显铈异常,Eu/Sm平均值0.38;Th/U比值大,与岩浆成因的重晶石稀土元素分配模式类似,显示岩浆成因。燕山期断裂构造叠加在早古生代二郎坪群及张家庄岩体内,沿断裂充填形成的成矿时代不早于(108±1)Ma的脉型轻稀土矿床。矿床成因为壳幔混源、受断裂构造控制的石英脉-蚀变岩型。主要找矿标志:在断裂构造中充填物为石英脉及萤石化、重晶石化、黄铁矿化等蚀变岩,以及弱的Th放射性异常,较低的U含量。     

THE WOLVES AND LAMBS OF THE CREATIVE CITY: THE SUSTAINABILITY OF FILM AND TELEVISION PRODUCERS IN LONDON

ABSTRACT. The sustainability of creative producers‐businesses and individuals‐depends in part on the state of the urban environment, especially the one of the street. Relationships with the street differ among creative producers with different power positions and levels of embeddedness in street life. Thus an approach to the sustainability of the creative city needs to move beyond the simplistic ideals of “mixed use” and “vitality” to an understanding of the complexity and continuity inherent in the production of creative spaces with respect to the multiple transactions of both the strong and weak stakeholders involved‐the “wolves” and “lambs.” The example used in this article, which draws on evidence from interviews with producers, is the film and television industry in Camden Town, London, in relation to the “experience” economy.     

丽江古城客栈经营者社会责任缺失研究
