Application of Correspondence Analysis in the Assessment of Mine Tailings Dam Breakage Risk in the Mediterranean Region

A new statistical approach for preliminary risk evaluation of breakage in tailings dam is presented and illustrated by a case study regarding the Mediterranean region. The objective of the proposed method is to establish an empirical scale of risk, from which guidelines for prioritizing the collection of further specific information can be derived. The method relies on a historical database containing, in essence, two sets of qualitative data: the first set concerns the variables that are observable before the disaster (e.g., type and size of the dam, its location, and state of activity), and the second refers to the consequences of the disaster (e.g., failure type, sludge characteristics, fatalities categorization, and downstream range of damage). Based on a modified form of correspondence analysis, where the second set of attributes are projected as "supplementary variables" onto the axes provided by the eigenvalue decomposition of the matrix referring to the first set, a "qualitative regression" is performed, relating the variables to be predicted (contained in the second set) with the "predictors" (the observable variables). On the grounds of the previously derived relationship, the risk of breakage in a new case can be evaluated, given observable variables. The method was applied in a case study regarding a set of 13 test sites where the ranking of risk obtained was validated by expert knowledge. Once validated, the procedure was included in the final output of the e-EcoRisk UE project (A Regional Enterprise Network Decision-Support System for Environmental Risk and Disaster Management of Large-Scale Industrial Spills), allowing for a dynamic historical database updating and providing a prompt rough risk evaluation for a new case. The aim of this section of the global project is to provide a quantified context where failure cases occurred in the past for supporting analogue reasoning in preventing similar situations.     

Stochastic hydrology: An introduction to wet statistics for dry statisticians

The paper is intended to give non-initiates some idea of the nature of stochastic hydrology. After a brief historical review it concentrates on three recent examples of stochastic modelling procedures that have aroused interest among hydrologists, namely the Hurst Effect, Short-Term Runoff Models, and Stochastic Reservoir Theory.     

魏晋南朝时期的堰埭建设

堰埭建设在水利建设史上被长期忽视。其肇始于先秦,发展于魏晋南朝,在农业水利和军事防御两个方面均体现出独特的功能。一般而言,堰多用于农田灌溉、排洪抗涝、军事斗争等方面;埭则兼用于内河水道航运方面,形成此期重要的人工水道,并因此成为政府埭税的重要依托。堰埭建设对古代政治、经济及社会发展产生了深刻的、综合性的影响。     

The dilemmas of pro-development actors: viewing state–ethnic minority relations and intra-ethnic dynamics through contentious development projects

Studies of ethnic minority peoples in Asia have long focussed on the relations between ethnic minority communities and the modern state and on the role of development in shaping these relations. This paper is concerned with how ethnic minorities respond to the state-led development. While there are numerous studies focussing on the collective agency of ethnic minorities opposing development projects, few studies consider the agency of pro-development actors. Pro-development actors are usually dismissed as co-opted, manipulated, inauthentic, or elite-driven, yet they can offer crucial insights into understanding state–ethnic minority relations and particularly intra-ethnic minority relations. This paper concentrates on pro-dam actors from the Lepcha minority in the Indian state of Sikkim to make four interlinked arguments. First, examining pro-development actors breaks the homogenous view of state–ethnic minority relations and shifts the focus to intra-ethnic relationships. Second, collective agency of ethnic minorities is not fixed in a particular relationship with the state nor does it have a particular position on development. Third, the long-term experience of development is vital in understanding how ethnic minorities manoeuvre and alter their position on contentious projects. Lastly, analysis of pro-development actors creates major dilemmas for researchers which are not easily overcome.

20世纪30年代中国小说理论之变迁

茅盾在20年代末提出了突出时代性的“新写实主义”。相应地,他对鲁迅小说的评价也发生了变化,由此,他的文学观与后期创造社所提倡的普罗文学观就趋同了。其时,写实倾向大大地压过了表现自我的倾向,第一人称的写法遭到了批评。文学界展开了对于浪漫谛克及庸俗现实主义的批判,现实主义本身也发生了深刻的嬗变。在这股更新了形态的现实主义潮流中,又有着以茅盾为代表的重视艺术表现和以阳翰笙为代表的注目于转换立场与克服旧意识的两种不同倾向。鲁迅则以一种面向新时代的态度,并且以他深刻的经验,指出了当时小说创作的正确途径,解决了作家与所写题材的关系问题。
