    根据融资融券交易制度发展的内在要求和资本市场稳步发展创新的客观需要,我国适时适势推出了转融通业务。转融通业务的推出不仅进一步深化和完善了我国融资融券交易制度,也为融资融券的集中监控创造了条件,但其双重杠杆效应也可能会从整体上加剧我国股票市场的波动。 本文通过采用Hsiaoetal.(2012)提出的基于面板数据的政策效应评估方法,从样本个股的微观视角研究了转融通业务对我国股票市场波动率影响的宏观议题。本文首先通过设立实验组和对照组,利用对照组样本个股波动率来拟合构造实验组样本个股的反事实波动率,并对比分析实验组样本个股真实波动率与由对照组构造的反事实波动率之间的差异,发现转融通业务的推出有效...According to the actual needs of the inherent requirement of the margin trading system`s development and the steady development of the Chinese capital market`s innovation, China timely and suitable potentially launched the refinancing business.

    细胞的生长、分化、分裂等生命过程都需要能量。能量应激反应是细胞维持自身能量稳态,保证胞内生理生化反应正常进行的极其重要的机制之一。mTOR信号通路通过调控蛋白翻译、细胞生长、自吞噬等方式参与调节细胞的能量应激反应。p38信号通路是熟为人知的应激反应调节通路。但是人们对p38信号通路是否在能量应激反应中起作用仍不了解。我们的研究表明p38beta-PRAK激酶级联通路参与调节mTOR所介导的能量应激反应。p38beta或PRAK基因缺失都可以阻断mTOR所介导能量应激反应。另一方面,能量应激刺激物可以激活p38beta-PRAK信号通路。这些结果表明了p38beta-PRAK是mTOR所介导的能...Energy is one of the essentials for cellular growth, differentiation and division.

    On the Development and Guarantee of the Right to Defense in Sentencing in China——Based on Provisions of American Law

    作为大陆法系国家,我国在刑事诉讼中一直以来都存在着重定罪、轻量刑的弊端。在刑事诉讼的侦查、起诉和审判阶段,传统以来重视的都是被告人罪与非罪、此罪与彼罪的问题,而与被告人切身利益相关的量刑问题常被忽视。随着观念的发展和法治的进步,近年来最高人民法院开始推行并不断强化量刑规范化改革。2010年10月1日“两高三部”的《关于规范量刑程序若干问题的意见(试行)》开始实施,该意见规定了量刑程序与定罪程序的相对独立。在实践当中,目前公诉机关的量刑建议权已初具规模,但是作为辩方的量刑辩护权不管在理论或实践中都还仍被忽视。量刑辩护权的这种现状,令刑事诉讼在量刑环节的控、辩双方两造对立局面无法形成。所以为保护被...As a Civil Law country, China has been focusing on convicting but contempt sentencing in criminal procedure.
