基于SVAR模型对商品价格波动和居民消费关系的讨论
Discussion Based on the SVAR Model of Commodity Price Volatility and Consumer Relations
 [PDF]


E-Commerce Letters (ECL) , 2012, DOI: 10.12677/ECL.2012.13005
Abstract:

本文运用结构向量自回归(SVAR)模型,深入分析了2000年到2012年月度商品零售价格指数与居民消费价格指数二者之间的关系,进行了相应的单位根检验,在VAR模型的基础上做出SVAR模型,由此获得了该模型中两变量长期稳定的关系,分析得出,二者受自身前期影响较大,且上期商品零售价格对于居民消费价格有明显的正相关影响(影响系数为0.44)。并在此基础上建立了脉冲响应函数,继而做出了(SVAR)模型的脉冲响应函数分析。

This paper tries to analyse the relationship between the retail price index and consumer price index with the structural vector auto regression (SVAR) model when it was 2000 to 2012 monthly. With the VAR model we have the unit root test, in which we get the long-term stable relationship between two variables in the model analysis. With their own pre-impact, the retail price has a significantly positive effect on the consumer price (which affects coefficient of 0.44). On this basis, with the establishment of the impulse response function we make (SVAR) model impulse response function analysis.

 

微博用户对剩男剩女的社会态度研究——基于微博文本情感倾向分析

 [PDF]

,
Advances in Social Sciences (ASS) , 2015, DOI: 10.12677/ASS.2015.42016
Abstract:
本研究探讨了网络用户对剩男剩女的社会态度。采用微博文本情感倾向分析的方法对1000条新浪原创微博进行态度研究。采用微博文本情感倾向分析的方法对1000条新浪原创微博进行态度研究,其结果显示微博用户对剩男剩女群体持负向态度。另对标签为剩男剩女的60名新浪微博用户近期发表的900条原创微博进行情感倾向性分析,发现剩男剩女群体的微博呈中性态度,且剩男和剩女的微博关注话题存在明显性别差异。本研究结果对于社会正确理性看待逐渐增多的剩男剩女具有一定的启示意义,对剩男剩女在择偶问题上树立正确择偶观具有引导作用。
This study investigated the Internet users’ social attitude towards leftover males and females. Re-lated to the topic of leftover males and females, 1000 original micro-blog messages selected from Sina Weibo were used to identify the emotional tendencies of these messages. The results showed that the micro-blog users held negative attitude towards leftover males and females. In addition, the emotional tendencies of the 900 original micro-blog messages that were recently published from 60 Sina Weibo users who were marked by leftover males or females were analyzed as well. The results showed that the emotional tendencies of these messages were neutral. Besides, there were dramatically differences on the topics focused by leftover males and females. The research not only induces a rational social attitude towards leftover males and females, but also plays a guiding role for them in setting up the correct conception on choosing spouse.

GUI抽象描述模型研究
,
计算机科学 , 2005,
Abstract: 图形用户界面(GUI)是各种计算机应用的一个重要组成部分。但是越来越多的缟程语言和GUI工具包使得开发跨平台的GUI也变得越来越繁琐。同时,日趋庞大和复杂的数据,也迫使开发者在维护GUI相关数据方面付出更多的努力。本文从分析MVC设计模式入手,力图从更高的层次上对GUI及其相关数据的描述模型进行归纳和抽象,提出并形式化描述了一种GUI抽象描述模型,基于该模型的GUI数据建模算法和绑定模型。最后简单介绍了该描述模型基于XML的实现语言——GUI XML。

中毒性心肌炎引发的恶性心律失常
Malignant Arrhythmia Caused by Toxic Myocarditis

Asian Case Reports in Vascular Medicine (ACRVM) , 2016, DOI: 10.12677/ACRVM.2016.41001
Abstract:

临床上,中毒性心肌炎引发恶性心律失常的病例少有报道。我们汇报一位中年患者吸入污染毒物后出现恶性心律失常的病例。特别是患者在短时间内出现的心电图动态变化令人迷惑,值得探究。我们也提出在类似情况下积极处理的建议。

In clinic, there are few cases of malignant arrhythmia caused by toxic myocarditis. We report a case of malignant arrhythmia following a middle-aged patient who was contaminated with toxic pollution. In particular, the change of electrocardiogram of the patient in short duration is confusing. It is worth exploring. Suggestions for active treatment in similar cases are also presented.

西南农牧区生存性碳排放特征与实例论证—以云南省兰坪县和香格里拉县为例

Abstract:
随着社会经济的发展,家庭生活用能是大气中温室气体CO2重要来源之一。通过介绍世界各国对大气中温室气体排放的历史累计及现状诠释家庭生存性碳排放的概念而且对家庭消费的碳排放进行计算和分析可以反映不同地区因社会经济发展水平不同,其碳排放的本质特征特别是我国是一个多民族的国家,南北方自然人文环境差别大本文以我国云南省的兰坪县和香格里拉县为例,结合实地考察和问卷调查,提出家庭生存碳排放评估的意义和指标体系,计算农牧区人均能源消耗碳排放量和食品消费碳排放量。研究结果表明:在能源方面,主要是以生物质燃料和电能,特别是对薪柴的使用高达98.76%;在食物方面,人均食物消费碳排放总量为76.52 kg,以粮食消费占主导,占食物总消费量的81.30%。该区农牧民人均食物消费碳排放只是美国的50.42%,加拿大的56.19%,日本的78.76%,属于基本生存线碳排放。
With the development of society and economy, household energy consumption is one of the important resources for CO2 emissions. Through the introduction of the world’s historical emissions and present situation to the atmosphere, this paper explained the concept of household survival carbon emission. And then calculating and analyzing the household consumption of carbon emissions, it could reflect the nature of its carbon emission, due to the difference of area social economic development level. Taking Lanping county and Shangri-la countyofYunnanprovince as examples,

Abstract: 设为Caratheodory函数。最近研究两点边值问题的解的存在性的工作很多,但都离不开如下三类关键性条件:Landesman-Lazer条件、符号条件及g对变量u的单调性假设。我们在不受这三类条件限制的前提下,得到一个存在性结果。
我国保证债务诉讼时效问题研究

中外法学 , 2011,
Abstract: 保证期间是保证债务所附加的一个否定的解除条件:就一般保证而言,债权人必须在保证期间内对债务人起诉或申请仲裁,并在相关执行程序结束后及时通知保证人,否则,保证债务消灭;就连带保证而言,债权人必须在保证期间内通知保证人主债务未受清偿,否则,保证债务消灭。债权人对保证人的保证债务请求权从主债务履行期届满时可行使,其诉讼时效,或者从主债务履行期届满时起算(依传统民法),或者从债权人要求保证人承担保证债务时起算(依《民法通则》)。保证期间和保证债务诉讼时效是两个平行的、互不相关的、互不影响的期间。先诉抗辩权的存在并不否认债权人对保证人的保证债务请求权。一般保证中,主债务诉讼时效中断,保证债务诉讼时效是否随之中断,应依诉讼时效起算点的不同设计而有别。连带保证中,主债务诉讼时效中断,保证债务诉讼时效不随之中断。主债务诉讼时效中止,保证债务诉讼时效不随之中止。
美国专利再审查制度评析

比较法研究 , 2014,
Abstract: 我国现行专利法在专利权无效判断问题上采取的是专利行政机关享有宣告专利权无效的权限,法院在侵权诉讼中不应就专利权的效力问题进行判断的做法。由于认识到这种绝对行政单轨制的种种问题,具有代表性的改革意见均体现出了崇尚美国专利权无效判断的司法主导制度的倾向。但是,自20世纪80年代起美国通过历次专利法修改,逐渐改变了原有司法主导的单轨制,加强了行政机关在专利权无效判断的权重。显然这一变化与我国学界对于美国专利权无效判断制度的理解大相径庭。特别是2011年美国专利法的修改又进一步确认了加强行政机关专利权无效判断再审查的趋势,值得深省。有必要从制度论上探寻上述发展趋势的来龙去脉,进而对建立与我国专利权有效性判断规范功能相适应的制度有所裨益。
