    在欧盟成员国内,离婚的实体法规则与冲突法规则均有诸多差异,面对欧洲一体化的进程,各国对离婚的不同规定阻碍了欧盟内部人员的自由流动。欧盟理事会于2010年12月20日通过了《关于在离婚和司法别居法律适用领域贯彻加强型合作的理事会(欧盟)第1259/2010号条例》,该条例统一了欧盟离婚事项的法律选择规则,在加强离婚法律适用确定性、预见性和灵活性的同时给欧盟内人员的流动提供了便利。特别是该条例在离婚的法律适用上引入了意思自治原则,反映了意思自治原则向涉外离婚法律适用领域扩展的趋势。欧盟在离婚领域统一法律选择规则的举措可以给其他国家涉外离婚法律适用立法提供借鉴。我国于2010年10月28日通过了《中...Within the European Union, as to the substantive and conflict of law rules in divorce matters, there are many differences between member states. Facing with the process of European integration, different rules of divorce hinder the free movement of persons within the Union.

    我国国民经济和社会发展“十二五”规划指出,要把扩大消费需求作为扩大内需的战略重点。作为拉动经济增长的重要力量,居民消费在经济发展过程中未起到显著作用,很大程度上是缘于社会保障制度的不完善,因此,研究社会保障支出与居民消费的关系,具有重要的理论意义和现实意义。由于我国社会保障支出以地方政府为主,本文选取在海峡西岸经济区中居核心地位的福建省为研究对象,这对推进福建省经济发展和海西建设都有一定的现实意义。 本文通过对福建省财政社会保障水平现状进行定性分析,分别介绍福建省财政社会保障支出的特点、水平和弹性,经过数据分析发现福建省社会保障存在社会保障覆盖面窄、支出水平较低、城乡差距大、政府职责不明确和...The Twelfth Five-year Plan of the China argues that the expanding consumer spending is the strategic points of the expansion of domestic demand.

    建立完善的城镇住房保障制度,是对市场机制的必要补充,也是国家社会政策与社会保障制度的重要组成部分。近年来,深圳由于过于依赖市场配置,忽视住房保障制度建设,产生了住房供应的结构性失衡,在土地资源短缺、人口压力以及人居环境迫切需要改善等多方面因素共同影响下,住宅房价大幅上涨,中低收入人群相对高昂房价显示出较低的支付能力,难以直接通过市场解决住房问题。2006年,深圳市政府结合地区实际情况,构建了对中低收入人群以经济适用住房、公共租赁住房和廉租住房等作为保障方式的住房保障体系,完善了住房保障制度,加大建设力度,并将于“十一五”期间提供14万套保障性住房解决低收入家庭住房困难问题。由于新的住房保障制度...To establish an adequate housing guarantee system is the necessary suppliment to the market economy, and an important component of the state social policy and social security system.

    1960年代后期,蒋介石在台湾发起声势浩大的"中华文化复兴运动",旨在宣扬三民主义并自命为中华文化的道统传承者。为了促进中华文化的复兴,发展三民主义建设,以教育为本,极力倡导青少年学习中华传统文化,以望其成为复兴中华的斗士,为"光复"大陆冲锋陷阵。时任国民党中央评议委员的萧瑜远在乌拉圭,他提出"第三代国民教育"的说法,将当时的台湾小学生视为第三代国民,主张重视第三代国民教育。本文根据这一说法,对中华文化复兴运动初期的台湾国民教育进行梳理

    采用粉末微电极技术改善电流型酶电极的输出性能(英文)

    Get PDF
    由于酶反应的特异性,酶电极在检测生物底物的工作中得到了较广泛的应用.然而电流型酶电极有以下的缺点,包括响应电流低,活性组份流失造成的电极使用寿命下降以及响应电流的非线性等.本文根据粉末酶电极模型进行了动力学分析,得出在两种极端情况下粉末酶电极的电流响应动力学公式,以及由响应电流估算表观米氏常数的方法.采用了两种粉末酶电极(C-PU-GOD和C-AQ-DBFc-GOD)对理论分析进行了验证.实验结果与理论推导较好地吻合,均表明采用粉末微电极技术可显著地提高酶电极的响应电流和扩展酶电极响应的线性范围作者联系地址:武汉大学化学系电化学研究
