五四新文化运动和五四文学革命

五四爱国运动是在五四新文化运动的催生下爆发的,它同时又扩大深化了五四新文化运动。五四新文化运动是中国的文艺复兴,是一场对民族文化进行批判和创新的运动。五四文学革命则是五四新文化运动的主要内容,其基本精神是思想自由、个性解放,也就是人的解放。     

河南汉族群体D4Satt、D5Saat miniSTR基因座遗传多态性

在法医学实践中,严重降解或者微量的生物检材采用STR分型,结果常不理想,而miniSTR技术是有效的一种检测方法[1]。本文从人类基因组DNA序列中查找并对D4Satt、D5Saat2个miniSTR基因座进行分型检测,希望可在日常法医学鉴定中作为核心STR基因座的补充[2]。1材料与方法1.1样本和DNA的提取134例河南汉族健康无关个体枸橼酸钠抗凝血样取自郑州市中心血站。采用酚-氯仿法提取DNA。1.2引物设计从GeneBank上下载4、5号染色体DNA序列,用Tandem repeats finder软件在距常用STR基因座较远的区域(50Mb以外)查找重复单位为3bp,连续重复12次以上的STR基因座。用Primer3软件设计引物,使扩增片段在150bp以内。引物由上海生工生物工程技术服务公司合成(表1)。1.3 PCR扩增及产物检测PCR扩增体系总体积20μL,包括1ng模板DNA,10×Buffer(含Mg2+1.5mmol/L)2μL,10mmol/LdNTPs 0.4μL,100μmol/L正反向引物各0.1μL,Taq表1 2个MiniSTR基因座一般信息基因座引物序列(5′-3′)重复区结...     

生产力发展视角下的五四运动研究

从生产力发展视角来研究五四运动,主要从两个方面：一是从生产力发展的视角来探讨五四爱国运动发生、发展的起源;二是研究五四新文化运动对社会生产力发展所起的作用。生产力发展对于五四爱国运动的作用是显性的,当时生产力发展的落后状况是导致爱国运动爆发的经济根源,而五四爱国运动也在一定程度上促进了社会生产力的发展。     

The analytical profile of some 4-methylthioamphetamine (4-MTA) homologues

The 4-methylthioamphetamine (4-MTA) is a sulphur-containing amphetamine-type stimulant (ATS), which appeared on the illicit market in Europe at the end of 90s. For the purpose of this study, several N-alkyl homologues of 4-MTA, including 4-methylthiomethamphetamine (4-MTMA), 4-methylthioethylamphetamine (4-MTEA), 4-methylthiodimethamphetamine (4-MTDMA), 4-methylthiopropylamphetamine (4-MTPA) and 4-methylthiobutylamphetamine (4-MTBA) were synthesized. The homologues were characterized by means of gas chromatography/mass spectrometry (GC–MS), infrared (IR) spectroscopy and the magnetic resonance spectroscopy (¹H and ¹³C NMR). The gas chromatography and mass spectrometry properties of their acetyl, trifluoroacyl (TFA), pentafluoropropionyl (PFP) and heptafluorobutyryl (HFB) derivatives were also investigated and discussed.     

Funds sharing regulation in the context of the sharing economy: Understanding the logic of China's P2P lending regulation

“Sharing economy” is an umbrella term that encompasses a wide range of digital platform-based activities that includes P2P lending and other forms of internet-based lending. The core aim of the sharing economy is to leverage the utilization of idle capacity. P2P lending can not only be used to leverage small amounts of money on the lender's side, but also be used to promote financial democracy and inclusion both on the lender and borrower's sides. P2P lending regulation, therefore, should place an emphasis on the utilization of dead money and promotion of financial democracy. This article scrutinizes the regulation of P2P lending in China. The existing regulatory system for P2P lending in China is built upon rules and regulations that have been designed solely with traditional brokers in mind. The article contends that the rigid rules placed on lending platforms limited their ability to maintain their roles as brokers and, in turn, heavily endangered the commercial sustainability of P2P platforms, thereby harming the sharing economy's openness and inclusivity. Additionally, the article argues that the fact that there is no limit on the amount a lender can invest poses a threat to the notions of leveraging idle money and financial inclusivity. The closed-ended P2P lending regime in China would cause some chilling effects to financial innovation in the P2P lending industry, and in a wider sense, the rising FinTech sector. Regulators in China need to cope with these challenges in a flexible but pragmatic manner, and particularly make use of the benefits the sharing economy may bring to the Chinese economy more broadly.

A 26plex Autosomal STR Assay to Aid Human Identity Testing*†

Abstract: A short tandem repeat multiplex assay has been successfully developed with 25 autosomal loci plus the sex‐typing locus amelogenin for a total of 26 amplified products in a single reaction. Primers for the loci were designed so that all of the amplicons present were distributed from 65 base pairs (bp) to less than 400 bp within a five‐dye chemistry design with the fifth dye reserved for the sizing standard. A multiplex design strategy was developed to overcome challenges encountered in creating this assay. The limits of the multiplex were tested, resulting in the successful amplification of a wide range of genomic DNA sample concentrations from 2 ng to as low as 100 pg with 30 cycles of PCR. The 26plex has the potential to benefit the forensic community for reference sample testing and complex relationship evaluation.     

Drittschadensliquidation

Blo?e Schadensverlagerung auf einen Dritten soll den Sch?diger von seiner Ersatzpflicht nicht befreien. Daher kommt es, soweit der Ersatzanspruch nicht ohnedies durch Legalzession auf den Dritten übergeht, zur Drittschadensliquidation durch den unmittelbar Gesch?digten. Der Beitrag untersucht dies für verschiedene Fallgruppen und hebt die Bedeutung der Schadensverlagerung für die Bemessung des Umfangs des Schadenersatzanspruchs sowie zur Abgrenzung von Drittschadensliquidation und Vertrag mit Schutzwirkung zugunsten Dritter hervor.
