Capital Mobility and Current Account Imbalance: Nonlinear Threshold Vector Autoregression Approach

In this study, we utilize the growth rate of gross domestic product as the threshold variable to construct two nonlinear threshold vector autoregression models to re-examine the findings in Yan (2007 Yan, Ho-Don. 2007. Does Capital Mobility Finance or Cause a Current Account Imbalance?. Quarterly Review of Economics and Finance, 47(1): 1–25. [Crossref] , [Google Scholar]:23) that “current account imbalance causes capital mobility in developed countries; capital mobility causes current account imbalance in emerging countries.” The nonlinear causality test shows that the findings of Yan (2007 Yan, Ho-Don. 2007. Does Capital Mobility Finance or Cause a Current Account Imbalance?. Quarterly Review of Economics and Finance, 47(1): 1–25. [Crossref] , [Google Scholar]) can exist only in certain regimes and the primary factor that affects the causality between current account and financial account (and its components of foreign direct investment, portfolio investment, and other investment) is the asymmetry caused by the business cycle.     

中美知识产权"刑事门槛"争端的法律问题

In April 2007, the United States filed an application with the DSB of WTO with respect to the issue of criminal law protection mechanism of intellectual property rights in China, which was the first dispute accepted by the DSB arising out of the issue of criminal law protection mechanism of intellectual property rights. The core of the dispute of the case is how to interpret the “commercial scale” under Article 61 of the TRIPS Agreement as the “criminal threshold”. It can be seen from the practice of the interpretation of the DSB that while each WTO member is entitled to interpret the term “commercial scale”, the boundary of interpretation is subject to Article 61 of the TRIPS Agreement. It is unnecessary for China to lower her “criminal threshold”, since China’s criminal law protection in intellectual property policy is in compliance with the TRIPS Agreement. In fact, the United States should change from lowering the criminal threshold to how to strengthen the criminal crackdown on piracy under the circumstance of lowering the price of genuine works when imposing pressure on China in the protection of intellectual property rights. He Xiaoyong, Ph.D, is presently a professor in the Faculty of International Law in the University of East China University of Political Science and Law. He studied as a visiting scholar at the University of San Francisco (2001). He was awarded a Chevening Scholarship in 2002 sponsored by British Council and Shanghai Outstanding Teacher Award in 2004. He has released more than 80 academic articles on WTO issues and international financial law, and his monographs include Legal Aspects on Supervision under Financial Globalization (2002), International Trade Dispute Settlement and China’s Perspective: Under the WTO framework (2006) and new issues under the WTO (2008).     

同频音掩蔽试验及其在法医学鉴定中应用的研究

目的应用同频音掩蔽试验观察不同个体最小对侧掩蔽级(MCML)与主观纯音听阈之间的关系,进而通过MCML判定被试者主观真实听阈。方法30例受试者(60耳)分别进行纯音测听,首先测出双耳的纯音听阈,然后应用同频音掩蔽试验测试各个频率的MCML。结果当被掩蔽耳的声强处于阈值时,掩蔽耳的MCML与主观纯音听阈差值在0～30dBHL之间,其中差值在10dBHL以内的占82.4%,在15dBHL以内的占97.1%;当被掩蔽耳的声强处于阈上10dBHL时,掩蔽耳的MCML与主观听阈间差值在0～35dBHL之间,其中差值在25dBHL以内的占90.5%,在30dBHL以内的占98.1%。结论利用同频音掩蔽试验可以准确地判定各个频率被掩蔽耳的真实主观听阈。特别是对于语音范围内听力状况的法医学评定更具有特殊的意义。     

应用ABR法评定外伤性耳聋

本文通过对40例外伤性耳聋的症状、病变和听力检查,重点讨论了鼓膜损伤所致的听力障碍,其损伤程度不超过50dB,给法医学鉴定中耳损伤程度提供了客观数据。进一步验证了ABR检查在判定听力损失的意义,对夸大、伪聋的识别优于其它听力检查。从临床耳聋程度分类法就《人体重伤鉴定标准(试行)》中,关于听力损伤的重伤标准进行了探讨。     

论公共视阈下的思想政治工作

文章从“公共视阈”这一新的视角来考察思想政治工作,提出思想政治工作本质上是一种公共行为;生活世界是思想政治工作的唯一源泉;互为主体是思想政治工作的核心特征;对话是实现思想政治工作的重要途径。     

对完善我国《个人所得税法》的思考

随着中国社会经济的发展,个人所得税在调节个人收入,维护社会公平方面的重要意义将更加凸显.我国现行的《个人所得税法》存在的主要问题有:税制模式不能体现纳税人税负的公平合理;个人所得税的征收范围窄,不利于发挥税收的调节作用;费用扣除标准的设定不合理;税率设定复杂显失公平;税收征管缺乏力度;全社会依法纳税的意识依然淡薄,纳税义务人故意隐瞒收入.其改进方案包括:选择合理的税制模式;拓宽个人所得税的征税范围,减少减免税项目;调整费用扣除标准;税率调整;加强税收源头控制,防止税款流失;加大对偷漏个人所得税行为的查处、打击力度,维护法律的严肃性.通过有针对性的改革,进一步修改、完善适合我国社会主义市场经济发展需求的科学的《个人所得税法》.     

芪归糖痛宁颗粒对大鼠糖尿病周围神经病变的影响

目的 观察芪归糖痛宁颗粒对大鼠糖尿病周围神经病变(diabetic peripheral neuropathy, DPN)的疗效，并探讨其作用机制。方法 以链脲佐菌素(streptozotocin, STZ)一次性腹腔注射复制DPN大鼠模型。于模型复制第3天起，各治疗组分别灌胃给予相应的受试药物，正常组和模型组灌胃给予等容量溶媒，疗程8周。实验结束后，测定大鼠热痛阈值、血液流变学指标、血清神经生长因子(nerve growth factor, NGF)、髓磷脂碱性蛋白(myelin basic protein, MBP)的含量，同时取固定部位坐骨神经，用苏木精 伊红染色观察坐骨神经组织病理学变化。结果 与模型组比较，芪归糖痛宁颗粒组能明显改善DPN大鼠坐骨神经病理组织学损伤程度，同时降低大鼠热痛阈（P＜0.05），降低大鼠全血黏度低切、中切、高切，血浆黏度，红细胞聚集指数及MBP含量（P＜0.05，或P＜0.01），升高血清NGF含量（P<0.05）。结论 芪归糖痛宁颗粒对大鼠DPN具有一定的治疗作用。     

芪归糖痛宁颗粒调节炎性因子预防糖尿病周围神经病变的机制研究

目的 通过观察芪归糖痛宁颗粒预防性给药对相关炎性因子的影响，探究其改善糖尿病周围神经病变(diabetic peripheral neuropathy，DPN)的机制。方法 将120只SD大鼠分为正常组，模型组，芪归糖痛宁颗粒高、中、低剂量组和甲钴胺组，采用链脲佐菌素腹腔注射联合高脂饲料喂养法复制糖尿病大鼠模型，预防性给予相应药物8周，以运动神经传导速度（motor nerve conduction velocity，MNCV）和摆尾温度阈值评价DPN的改善情况，采用酶联免疫吸附法测定大鼠血清基质金属蛋白酶-1 (matrix metalloproteinase 1,MMP-1)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、白细胞介素-1（interleukin 1，IL-1）、单核细胞趋化蛋白-1（monocyte chemotactic protein 1,MCP-1)含量。结果 与正常组比较，模型组大鼠摆尾温度阈值显著升高（P<0.05），MNCV显著下降（P<0.05），血清MMP-1、TNF-α、IL-1和MCP-1均显著升高（P<0.05）。芪归糖痛宁颗粒对DPN大鼠的MNCV、摆尾温度阈值及血清MMP-1、TNF-α、IL-1和MCP-1的效应具有明显的剂量依赖性（P<0.05），不同剂量对不同指标的效应呈现不同的量效关系；不同剂量芪归糖痛宁颗粒与甲钴胺对DPN大鼠的MNCV、摆尾温度阈值及血清MMP-1、TNF-α和IL-1的效应相比较，差异均具有统计学意义（P<0.05）。结论 芪归糖痛宁颗粒能预防DPN，其机制与调控复杂的炎性因子网络有关，其效应具有明显的剂量依赖性。
