The introduction of Western science in order to change physical and operational aspects of Shanghai’s Huangpu River had been debated by Qing and Western officials since almost the beginning of its history as a Treaty Port. At stake in those debates was the perception of the river’s proper use: as a natural barrier for military defense, or as a conduit for global trade. After the Western powers unified to militarily suppress the Boxer Uprising in 1900, they attained their long-awaited goal of the right to transform the river for global trade as part of Article 11 of the Boxer Protocol: the Junpuju (or Huangpu Conservancy Board) was created and authorized by the central government to make the Huangpu River navigable for shipping vessels. Although the Junpuju continued the ethos of earlier extra-bureaucratic organizations established during the Self-Strengthening Movement, after 1901 the organization bore the authority of the central government. During the era of the New Policies, Qing officials were intent on revising the original terms of river conservancy so that they would be more favorable to Chinese sovereignty. At the same time, imperialist rivalries among the Western powers ruptured the apparent unity of the earlier alliance during the suppression of the Boxer Uprising. Before long, Western corruption in the Huangpu River dredging was brought to the attention of Qing officials, who deftly used it to recover Qing control over certain parts of the body of the river.  相似文献

从《气候变化框架公约》进展看当前国际环境关系   总被引:1,自引:0,他引:1  
自1992年联合国环境与发展大会缔结了为气候变化问题上的全球合作提供法律框架的《气候变化框架公约》以来,国际上已经历六次缔约方大会。虽然1997年其第三次缔约方会议签订了具有削减温室气体排放数量和时间限制具体目标的《京都议定书》,取得了该领域的一个关键性进展,但最近在荷兰海牙召开的旨在就《京都协定书》的目标与措施达成具体协议的第六次缔约方会议却以失败而告终。纵观国际社会在《气候变化框架公约》问题上的后续行动进展,可以充分看出当前的国际环境关系具有环境问题政治化、环境关系复杂化、环境合作艰难化以及环境斗争激烈化的特点。这使中国今后在环境与发展的问题上将面临更加严峻的挑战,为此必须尽早采取有效对策。  相似文献

This paper outlines the first methodology for recording dental enamel hypoplasia in the high‐crowned dentition of modern and archaeological caprine teeth. The method has been developed and trialed on five caprine populations from Orkney (UK); two modern populations (Shetland and North Ronaldsay breeds) and three Neolithic assemblages from the archaeological sites of Knap of Howar, Skara Brae and Holm of Papa Westray. Problems associated with differential tooth wear, as well as the presence of coronal cementum, are discussed, and recommendations are given on the identification and recording of hypoplastic dental defects in caprines.

The column members of steel moment frames undergo high axial forces as well as inelastic rotations during a severe seismic event. The boundaries of these simultaneous structural demands on the columns of special moment frames have been investigated in this research. Based on the results of this investigation, dual cyclic loading protocols have been developed that represent both axial force and lateral deformation demands. Contrary to other loading scenarios that have been implemented in previous studies on steel columns, the loading protocols developed in this study include simultaneous axial and lateral loading cycles with varying amplitudes. The level of axial forces and story drifts tolerated by the columns of some typical Special Moment Frames (SMFs) has been investigated through performing nonlinear dynamic analyses. These frames have been selected with several configurations and different number of stories. The results of the nonlinear dynamic analyses have been processed to assess cumulative and instantaneous seismic demands on the columns of the chosen typical frames. Subsequently, dual cyclic loading protocols have been developed such that exerting these loading protocols on individual steel columns can result in structural effects close to the general seismic demands assessed in this study. Two separate dual loading protocols have been introduced for Design Earthquake (DE) and Maximum Considered Earthquake (MCE) seismic intensity levels.  相似文献

Abstract: This paper explores how a relatively successful global environmental treaty, the Montreal Protocol on Substances that Deplete the Ozone Layer, is currently undermined by US protectionism. At the “global scale” of environmental governance, powerful nation‐states like the US prolong their domination of certain economic sectors with the assistance of neoliberal discourse. Using empirical data gathered while attending Montreal Protocol meetings from 2003 to 2006, I show how US policy undermines the Montreal Protocol's mandate to phase out methyl bromide (MeBr). At the global scale of environmental governance the US uses a discourse of technical and economic infeasibility because, in the current neoliberal milieu, it cannot make a simply protectionist argument. The discourse, in other words, is protectionism by another name. While much of the literature in critical geography on neoliberalism has focused on de‐regulation versus re‐regulation, this paper illustrates how science, protectionism, and neoliberalism can become articulated uneasily and in sometimes unexpected ways.  相似文献

Abstract: This article traces the creation of a market for carbon sequestration by trees under the Kyoto Protocol on climate change, describing the problems encountered by UN negotiators as they attempted to abstract, isolate, quantify and commodify a process akin to breathing, which takes place naturally everywhere, anyway. It starts with an overview of the history of the negotiations that defined the commodity and the rules to govern its trade, creating the scarcity conditions for the market to work. It then goes over the key problems encountered and how they were solved. The analysis draws attention to time and risk as critical elements in reproducing uneven development, and suggests that this new market can be understood as an instance of capital involution—that is, an instance where a narrow pattern persistently repeated leads to ever increasing complexity but, instead of evolving into something new, it generates further entrapment.  相似文献

Abstract

This paper argues that the development of the Ecosystem Services framework, which has recently emerged as an internationally recognized framework for valuing ‘the ‘natural capital’ of ecosystems, presents a number of opportunities for heritage management and the archaeological record, arguing that the inclusion of archaeological and palaeoenvironmental ‘value’ within this framework presents an opportunity to incorporate heritage alongside a range of other critical ‘services’. It presents a short case study focusing on the problems facing the preservation of peatland archaeological sites and deposits in situ alongside developments within peatland conservation and restoration initiatives partly driven by the ability of healthy, functioning peatlands to sequester carbon and hence mitigate climate change. It is argued that this drive towards peatland re-wetting may bring both positive benefits and opportunities for heritage management but also presents a number of practical issues, which now require active engagement from the archaeological community.  相似文献
