民法典时代的宅基地"三权分置"实现路径

宅基地"三权分置"改革旨在保障宅基地使用权身份属性的基础上,扩大分享宅基地权益主体的范围,从而使宅基地的资产功能得以彰显。社会主体盘活宅基地有两种方式:第一,直接盘活宅基地。第二,通过盘活农房,间接盘活宅基地。对宅基地的直接盘活,分为对宅基地使用权的直接流转、转化为集体经营性建设用地使用权的流转、分离出物权性子权利流转、分离出债权性子权利法定租赁权流转,但是相关方式因违反土地为农民集体所有的内在逻辑、会造成宅基地大量流失、与《民法典》之物权法定原则、房地一体原则相悖等原因无适用空间。而对宅基地使用权的间接盘活则大有可为:在农房之上设立《民法典》新规定之居住权和租赁权,从而达到对农房的物权化和债权化盘活,通过采取宅基地所有权、宅基地使用权和农房居住权及租赁权的分置路径来实现改革目标。     

四种调补方对反复心理应激大鼠下丘脑及海马氨基酸含量影响的比较

目的 :观察调肝方、健脾方、补肾方及人参总皂苷对反复心理应激大鼠下丘脑及海马氨基酸含量的影响。方法 :大鼠随机分为正常组、模型组、调肝组、健脾组、补肾组和人参总皂苷组。采用OPA高效液相色谱分析法检测下丘脑、海马氨基酸含量。结果 :人参总皂苷组下丘脑谷氨酸(Glu)明显下降 (P <0 .0 5 ) ,健脾组与人参总皂苷组下丘脑天冬氨酸 (Asp)水平均明显低于模型组和正常对照组 (P <0 .0 1)。模型组海马Glu明显下降 (P <0 .0 5 ) ,补肾组、健脾组和人参总皂苷组海马Glu和Asp均明显升高 (P <0 .0 1)。调肝组、健脾组和人参总皂苷组下丘脑γ 氨基丁酸(GABA)和牛磺氨酸 (Tau)均明显下降 (P <0 .0 5或P <0 .0 1) ,补肾组下丘脑GABA明显下降(P <0 .0 1) ,模型组海马Tau明显下降 (P <0 .0 5 ) ,健脾组、补肾组与人参总皂苷组海马GABA和Tau均明显升高 (P <0 .0 1)。结论 :调肝方药的中枢作用部位可能主要在下丘脑 ,其作用机制可能与下调氨基酸水平有关 ;而健脾、补肾方药及人参总皂苷的中枢作用部位可能与海马和下丘脑都有密切关系 ,作用机制则与上调氨基酸水平有关     

论我国环境管理体制立法存在的问题及其完善途径

我国现行的环境管理体制立法存在着立法体系不完善、立法内容存在交叉和矛盾、某些立法授权不符合科学管理的规律等问题。为此 ,我国应当加强对环境管理体制立法的研究 ,注意借鉴国外环境管理体制立法的经验 ,加快制定综合性的环境管理体制立法。应将各单行立法中关于环境管理体制的规定具体化 ,及时修订与实际不符的法律规定。在立法程序上 ,改变由管理部门起草立法的方式 ,遵循先立法后改制的原则。并且在立法中引入公众对环境管理机构的监督机制     

Methods Meet Policy: Transnational Monitoring of the Israel–Palestine Conflict

For the past 2 years, the Kansas Event Data System project has been using event data and other web-based sources to produce quarterly reports on the Israel–Palestine conflict for the swisspeace (Swiss Peace Foundation) FAST Project, which is sponsored by Swiss Agency for Development and Cooperation and a number of non-governmental organizations. This paper describes the indicators that we are monitoring, the process we have developed to generate the reports, and the supplemental sources we are using. We address the issue of the differences between newspaper and news wire reports with respect to "media fatigue" effects and also analyze some of the strengths and weaknesses of this approach to conflict monitoring.     

山楂的HPLC指纹图谱研究

目的:采用高效液相色谱法(high performance liquid chromatography,HPLC)建立山楂药材指纹图谱,以控制其质量.方法:以绿原酸为参照物,采用HPLC分析山楂内有效成分,并利用计算机相似性评价系统对指纹图谱进行相似度分析.色谱柱为Diamonsil-C18(250 mm×4.6 mm,5 μm),采用冰乙酸和乙腈组成的缓冲溶液梯度洗脱,流速0.8 ml/min;检测波长325 nm.结果:精密度和重复性试验中,相对峰面积大于10%的共有峰的RSD均小于5%,符合<中药注射剂色谱指纹图谱实验研究技术指南>相关要求.结论:本研究建立的方法简单,重复性良好,可作为控制山楂药材的内在质量的标准.     

O型口蹄疫病毒VP1基因和牛集落刺激因子基因的融合表达

将O型口蹄疫病毒VP1基因和牛集落刺激因子(GMCSF)成熟肽基因共同克隆到原核表达载体pGEX6P1中,转化RS21后经IPTG诱导,实现了重组融合蛋白BoGMCSF/VP1在大肠埃希氏菌RS21中的高效表达,表达产物经SDSPAGE和Westernblotting分析,重组的蛋白质分子质量约为66ku,与预期大小相符。表达蛋白占菌体总蛋白的30%,表达产物以包涵体形式存在;包涵体提取物经变性复性,用透析方法提纯,得到高纯度的表达蛋白。     

网络遗产的若干法律问题研究

信息技术的迅猛发展与网络空间的快速膨胀,使得大量网络虚拟财产散布在网络中。网络虚拟财产在用户逝去时,继承人是否有权继承的问题,这一点无论是在理论界还是实践中都存有很大争议。本文拟从网络遗产的法律属性进行分析得出网络遗产属于他物权,认识到当前网络遗产的继承困境进而提出相关措施进行保护。     

Is the Assessment of Dental Age by the Nolla Method Valid for Eastern Turkish Children?

The aim of this study was to investigate whether or not the Nolla method is appropriate for Turkish children for the determination of the dental age (DA). A group of 719 children between the ages of 6 and 18 years were included in the study. DAs from orthopantograms by the Nolla method were estimated. The results obtained were compared with chronologic age (CA). Paired t and the Wilcoxon tests were performed. Both genders were underestimated in dental maturity when compared with the reference samples in total (-0.3 years) (p<0.01). The differences in girls were statistically significant in total and in all groups except for 7-7.9. The differences in boys between the CAs and DAs were not statistically significant in total and in all groups except for 7-7.9 and 8-8.9. Although the accuracy of this method was suitable for boys, according to our findings, it was not suitable for girls.     

Nanoscience and technology publications and patents: a review of social science studies and search strategies

We undertake a comprehensive review of more than 120 social science studies on nanotechnology, 90% of which are based on the analyses of the nanotechnology publications and patents. We discussed four intellectual debates formed by these studies, namely whether nanotechnology is an interdisciplinary field, whether nanoscience and nanotechnology are closely interlinked, whether nanotechnology development is path dependent and who is winning the global nanorace. We also conduct a comparative analysis of bibliometric search strategies used in the literature to harvest the publications and patents, including lexical queries, evolutionary lexical queries, citation analysis, and the use of core journal sets to identify nanotechnology articles. Because most of the compared strategies, except the one using 10 core journals in the field, share a core set of keywords and thus harvest a common batch of publications, they produce very similar ranking tables of the top subject areas and journals and the most prolific countries and institutions. Moreover, the core journal strategy does not provide a robust delineation of an emerging field such as nanotechnology due to the fact that nanotechnology related articles are published in a wide range of journals. Also, the different criteria for selecting the core journals will affect the analytical results dramatically.
