生猪疫病对猪肉贸易的影响及对中国的启示——来自台湾的口蹄疫案例

用台湾爆发口蹄疫的案例实证演绎了生猪传染性疫病对猪肉贸易的重大影响。研究认为:疫病预防和控制以及国际认可、国家兽医体制的控制能力以及生猪适度规模饲养是猪肉贸易健康发展的关键因素,因此,作为养猪大国的中国,必须吸取国际经验,完善生猪疫病预防和控制,促进猪肉贸易发展。

The State, Institutional Transition and the Creation of New Urban Poverty in China

Since the 1990s, the introduction of a market economy and the process of rapid urbanization have been accompanied by a new urban poverty related to lay‐offs and unemployment as well as by large‐scale rural–urban migration, which is different from the traditional urban poverty of the ‘Three Nos’ (no relatives or dependants, no working capacity and no source of income). This article focuses on new urban poverty in China under market transition and discusses the causes of poverty creation. Instead of considering Chinese new urban poverty only as a result of market mechanisms, it argues that the state as the manipulator of institutions and policies does matter in the creation of new urban poverty, and that the cleavages between the old and new institutions further intensify it. Specifically, the following aspects of the creation of new urban poverty are examined in detail: the adjustment of industrial policy, the reform of state‐owned enterprises, evolution of the household registration system, and the transformation of the welfare state.

Rainfall interception by Santa Monica's municipal urban forest

Effects of urban forests on rainfall interception and runoff reduction have been conceptualized, but not well quantified. In this study rainfall interception by street and park trees in Santa Monica, California is simulated. A mass and energy balance rainfall interception model is used to simulate rainfall interception processes (e.g., gross precipitation, free throughfall, canopy drip, stemflow, and evaporation). Annual rainfall interception by the 29,299 street and park trees was 193,168 m³ (6.6 m³/tree), or 1.6% of total precipitation. The annual value of avoided stormwater treatment and flood control costs associated with reduced runoff was $110,890 ($3.60/tree). Interception rate varied with tree species and sizes. Rainfall interception ranged from 15.3% (0.8 m³/tree) for a small Jacaranda mimosifolia (3.5 cm diameter at breast height) to 66.5% (20.8 m³/tree) for a mature Tristania conferta (38.1 cm). In a 25-year storm, interception by all street and park trees was 12,139.5 m³ (0.4%), each tree yielding $0.60 (0.4 m³/tree) in avoided flood control costs. Rainfall interception varied seasonally, averaging 14.8% during a 21.7 mm winter storm and 79.5% during a 20.3 mm summer storm for a large, deciduous Platanus acerifolia tree. Effects of differences in temporal precipitation patterns, tree population traits, and pruning practices on interception in Santa Monica, Modesto, and Sacramento, California are described.     

资产证券化基本法律问题之探讨

资产证券化是 2 0世纪最重大的金融创新之一 ,它在中国的推行是必然的。但目前我国的资产证券化刚起步 ,实践经验贫乏和稀缺 ,有关理论也很模糊且存在颇多分歧 ,导致了建立资产证券化法律制度的工作因没有明确的指导原则和标准而滞后。本文暂不讨论资产证券化涉及的具体法律问题 ,而是在分析资产证券化的资产和证券的特点和范围之后 ,概括出资产证券化的法律内涵 ,在此基础上抽象出资产证券化法的价值 ,以期使资产证券化的基本法律问题引起更多思考
