    背景:乙型肝炎病毒(HepatitisBvirus,HBV)感染可以引起肝脏损害,并可以持续慢性感染,HBV长期慢性感染会造成肝硬化、原发性肝癌等失代偿性终末期肝病,从而导致死亡,是我国乃至全球最重要的公共卫生问题之一。西藏自治区地处我国西北部,早期研究认为其属于HBV高流行地区,但目前对该地区HBV流行病学以及分子特征研究较少。为了解西藏自治区慢性乙型肝炎等重要传染病的流行情况和HBV的分子流行病学现状及特征,本研究于2012年通过血清流行病学调查,研究西藏林芝地区全年龄人群慢性乙型性肝炎等重要传染病尤其是HBV感染的流行现状和影响因素,评价该地区慢乙肝防治效果,并为其进一步制定预防和控制慢...Hepatitis B virus (HBV) infection is one of the most important public health problems in our country and even worldwide.

    论生态经济价值观的推进

    Abstract in Chinese: 传统的经济学大多建立在自然资源可无限开发利用的前提上,忽略了生态成本这一关键因素。只有摒弃以浪费资源为代价的传统经济生产方式,将生态增长视为新的社会发展衡量标准,才有可能形成稳定状态持续发展的经济。这种发展模式的转变与其说是经济变革,不如说是观念革新。新观念的关键在于如何将投资重点从对“物”的投资转向对“人”的现实的投资,其内在要求在经济、伦理、生态三个方面具体体现为知识投资、人的现实的再造以及整体的观念。Abstract in English: Most of the traditional economics based on the premise that the development and utilization of natural resources is unlimited, which neglects the environment and ecology cost. Only abandoning the traditional economic production mode at the expense of wasting resources and treating the eco growing as main measurable standard, can Steady-state Economy become possible. This kind of development model transformation is not so much economic change, as concept innovation. Which means that what matters is investment in man, not in things. The intrinsic requirements are knowledge investment, the reality of reengineering and the idea of the overall in three aspects of economic, ethical and ecological. [pp. 119-120

    住房公积金是职工的长期住房储金,其资金管理运作必须满足长效发展和稳健经营。相比商业性银行已经比较成熟的流动性风险管理实践经验,住房公积金行业仅仅20多年的发展,在面临日益严峻的流动性风险问题时,各地中心在实际工作中缺少全面且系统性的流动性风险管理经验,这就给公积金制度的长期平稳运行带来了巨大的考验。 本文以浙江省杭州市为例,首先回顾了杭州市近10年面临的流动性风险的各个阶段,分析其流动性风险的特点及影响,根据对流动性风险进行应对的详细措施与方案的整理,进而提出了缺失流动性风险的指导建议、风险预警能力不足、缺乏部门间配合、缺少标准化的措施等等风险管理中存在的问题。本文为解决上述这些疑难,以国内...The housing accumulation fund is a long-term housing savings, the capital management must meet the long-term development and prudent management.

    如今,海洋重金属污染已是最严峻的环境问题之一,会对海洋生态系统乃至人类造成巨大的危害,其中汞和镉是最有代表性的重金属,两者即使在低剂量下也会对海洋生物产生较高的毒性效应,而且会在生物体内累积并在食物链传递过程中有生物放大现象,最终威胁人类健康和生命安全。海洋桡足类日本虎斑猛水蚤(Tigriopusjaponicus),因其广泛的地理分布、相对短的世代周期、高的繁殖力、易于区分的雌雄形态及在海洋环境中重要的生态位等,已成为海洋生态毒理学研究的重要模式生物。因此本论文选取日本虎斑猛水蚤作为受试生物,研究长期多个世代暴露和恢复下汞或镉在该桡足类体内的累积状况及其对该动物6个重要生活参数(如存活率、无...By now, marine metal pollution has been one of the most serious environmental problems, and it potentially causes a great threat to marine ecosystem and even humans.

    Residents' Marginal Propensity to Consume and Fiscal Policy

    过去三十年的时间,中国的经济发展实现了快速腾飞,伴随着经济的持续快速发展,居民的生活和收入水平也相应地快速提高。但是我国的居民消费率(即居民消费占GDP的比重)却呈现出不断下降的趋势。尽管在一定程度上,赶超型经济体在经济高速增长阶段会表现出居民消费率下滑的现象,然而,目前中国的居民消费率下降之持久以及消费率之低已经超出了赶超型经济体在起飞阶段下降的合理范围。因此,促进居民消费,提高我国的宏观消费率,将对稳定经济发展、优化经济结构有重要且积极的意义。 从逻辑上分析,决定居民消费水平的不外乎两个因素,一是消费能力,另一个是消费意愿(边际消费倾向),且两者均会受到政府财政政策的影响。边际消费倾向不...Along with China's rapid economic development, the residents’ income level increases rapidly, but household consumption-output rate (the proportion of household consumption to GDP) presents a declining trend for a long time.
