四川省宣汉县樊哙镇滑坡的基本特征及形成机制分析 总被引:1,自引:0,他引:1
2009年7月16日21时30分,宣汉县樊哙镇古凤村大风滩发生了严重的滑坡灾害,其滑坡方量约50×104m3,最大滑移距离达40m,约10×104m3滑体物质进入河床,将约80m宽的河道堵塞过半(约40m)。滑坡造成民房垮塌和相关设施的毁坏,经济损失巨大。在对滑坡区的地质条件、降水特征等综合分析的基础上,本文根据滑坡形成的过程探讨了滑坡发育特征及形成机制。分析表明,该滑坡是暴雨造成前河河水水位上涨冲刷滑坡前缘所致,超强降雨起到了冲刷、顶托、楔裂、促动的作用。既存在有利于滑坡形成的地质地貌条件,又有不合理的人为活动的因素。深入研究樊哙镇古风村滑坡的形成条件和成灾机理,对该区地质灾害的预防与治理提供一定的技术支持,进而对我国西南地区存在与大风滩滑坡类似的临河型滑坡的灾害隐患点的减灾防灾工作也具有一定的借鉴意义。 相似文献

针对K39+715堆积型中型土质滑坡,简要描述了边坡的变形及其对公路路基及桥梁的影响,并从滑坡区的现场地质环境、地形地貌、水文地质特征、区域地质构造及人类活动等相关方面对边坡变形进行了分析,滑坡现处于蠕动挤压变形阶段,强降雨对边坡变形起加速及触发作用。基于传递系数法对边坡在自重;自重+地下水;自重+暴雨+地下水;自重+地震+地下水四种工况的稳定性进行了计算,确定了在不同工况下的安全系数,并提出了滑坡处治建议。结果表明:滑坡目前处于极限稳定状态,随着时间的推移和雨季来临,滑坡会进一步发展扩大和滑移。 相似文献

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field. 相似文献

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support. 相似文献

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research. 相似文献

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders. 相似文献

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion. 相似文献

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context. 相似文献

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates. 相似文献

This paper focuses on the fashion industry, one characterised by issues such as dramatic shifts in the scale and power of
major retail buyers in the market, the advent of retailer own brands, and the nature of sourcing and supply chain decisions,
issues that are increasingly global in nature. The aim of this research is to explore the nature of relationships between
UK high street multiple fashion retailers and their contracted suppliers, many of whom are entrepreneurial firms by most definitions
of the term. Four core themes emerge from the literature and provide a framework for the research, namely, power, process,
partnership, and people. The research approach was qualitative, and conducted over a period of twelve months. The paper ends
with an agenda for future research. 相似文献
