ABSTRACT: Data from a small forested catchment were used to model peak stream flow as a function of basic hydrologic variables associated with 112 rain storms. Rainfall depth and initial stream flow rate accounted for 87.1 percent of peak flow variability. Forty expressions of rainfall intensity (describing both the temporal sequence of intensity for 20 equal storm intervals, and maximum intensity for 20 separate interval lengths) were used in an attempt to improve the predictability of basic models. None of the intensity parameters improved predictability by as much as 2 percent, apparently because the most intense rainfall bursts generally occurred near the beginning of storm periods. Mean rainfall intensity for entire storms was generally as effective as any of the shorter interval intensities, and its use helped to linearize the relationship between peak flow and rainfall depth and duration. 相似文献

Bridging international relations and disaster studies: the case of disaster–conflict scholarship 下载免费PDF全文
Simon Hollis PhD 《Disasters》2018,42(1):19-40
International relations and disaster studies have much to gain by thinking critically about their respective theoretical and epistemological assumptions. Yet, few studies to date have sought to assess the potential value of linking these two disciplines. This paper begins to address this shortfall by examining the relationship between disasters and conflict as a research sphere that intersects international relations and disaster studies. Through an analysis of whether or not disasters contribute to intra‐national and international conflict, this paper not only provides a review of the state of the art, but also serves to invite scholars to reflect on related concepts from other fields to strengthen their own approaches to the study of disasters in an international setting. An evaluation of the conceptual and theoretical contributions of each subject area provides useful heuristics for the development of disaster–conflict scholarship and encourages alternative modes of knowledge production through interdisciplinarity. 相似文献

环境监管不同于环境管理。环境监管强调的是监督和管理的结合,二者不可偏废。而相应的对环境监管法律关系的理解也不能仅仅局限于管理的角度。要厘清我国环境监管法律关系,就要从主体、主体的权利与义务和客体等构成要素入手深入剖析,进而对我国环境监管立法完善进行有益的拓展。 相似文献

The thesis in this article is that both women's work and its invisibility are essential to development, and at two levels: to the economy of rural households and to the wider development process. For rural households, the case of Pakistan suggests that the veils that conceal women's work shield a portion of household production from the risks and extractions inherent in their involvement with development. This shielded production depends on off-farm natural resources of which the use is also veiled. For States and other development interests, the author suggests that women's work constitutes a subsidy which is intentionally invisible. The subsidy of women's labour is linked to a forest-to-farm subsidy. Women's invisible work, in other words, is not invisible because it is not seen, but because the process of economic development—for both rural households and States and other development actors—requires that it be hidden. 相似文献

The growing assumption thattransnational corporations (TNCs) will apply``best practice' and ``international standards'in their operations in developing countries hasseldom been checked against close observationof corporate behavior. In this article, Ipresent a case study, based on field research,of one voluntary initiative to useinternational standards and best practice forenvironmental protection in the AmazonRainforest, by a US-based oil company,Occidental Petroleum (Oxy) in Ecuador. The moststriking finding is that the company refuses todisclose the precise standards that apply toits operations. This, and the refusal todisclose other important environmentalinformation, make it impossible to verifyindependently Oxy's claims of environmentalexcellence, or assess the effectiveness of theinitiative. At the same time, Oxy uses theinvocation of international standards to wrapitself in a veneer of corporate responsibility;reassure government officials and localresidents; cultivate confusion about standardsand practices that apply to the operations;deflect meaningful oversight and transparency;and arbitrarily legitimize norms that have beendefined by special interests. In short,international standards offer great promise forneeded environmental improvements; but can alsobe used to impede, rather than advance,corporate responsibility and the development ofeffective environmental law at the nationallevel. These findings suggest that for theapplication of international standards to bemeaningful, the international community needsto move beyond statements of principle anddevelop mechanisms that can be used toevaluate, verify, and monitor independentlyenvironmental claims by TNCs. 相似文献

Tackling China’s grave environmental problems increasingly turns on questions of sub-national interjurisdictional relations. What are the conditions under which neighbouring localities cooperate in stewardship of the natural environment? What factors give rise to interjurisdictional conflict such as pollution spillovers? Through a combination of empirical and theoretical reflections, a research agenda to better understand these issues is outlined. First, China’s recent innovative approaches to the promotion of interjurisdictional cooperation are examined. An in-depth case study of interjurisdictional ecological protection ‘redline’ zones underscores the difficulties of inculcating environmental neighbourliness between local governments. Yet, a precise diagnosis of the problem remains elusive because too little is known about the underlying drivers of interjurisdictional relations in China. An analytical framework that draws insight from contemporary China studies and comparative environmental governance scholarship is offered for the study of interjurisdictional environmental relations in China. 相似文献

In the current media landscape, organizations often communicate about science directly with publics through online channels rather than relying on journalist gatekeepers. Online platforms present organizations with the opportunity to participate in two-way communication in order to increase engagement with science. The present study examined how the National Oceanic and Atmospheric Administration (NOAA) utilizes social media to interact with publics. Results suggest that NOAA does not fully utilize the dialogic potential of social media, which could enhance both the public’s science literacy and trust in science regarding climate change specifically. This study informs how public relations theory may complement science communication theory and practice as deficit model-thinking transitions to contemporary approaches for public engagement with science. 相似文献

矿业环境相邻关系的界定是相应环境产权私人化的途径。由矿业环境相邻权与矿业成员环境权双向对接组成的环境相邻关系,通过法律来约束矿山企业的环境相邻权和激励相邻对方的成员环境权而共同保护矿业环境。矿山企业一方给相邻对方合理施加容忍义务,相邻对方应当容忍非实质性的或当地通行的影响。成员环境权的保护,是基于物权而行使消除危险、排除妨害和恢复原状的请求权,基于债权而行使侵害赔偿请求权。 相似文献

Governance of environmental risk: new approaches to managing stakeholder involvement 总被引:1,自引:0,他引:1
Disputes concerning industrial legacies such as the disposal of toxic wastes illustrate changing pressures on corporations and governments. Business and governments are now confronted with managing the expectations of a society increasingly aware of the social and environmental impacts and risks associated with economic development and demanding more equitable distribution and democratic management of such risks. The closed managerialist decision-making of the powerful bureaucracies and corporations of the industrial era is informed by traditional management theory which cannot provide a framework for the adequate governance of these risks. Recent socio-political theories have conceptualised some key themes that must be addressed in a more fitting approach to governance. We identify more recent management and governance theory which addresses these themes and develop a process-based approach to governance of environmental disputes that allows for the evolving nature of stakeholder relations in a highly complex multiple stakeholder arena. 相似文献
