政府公共政策制定的模式和机制

政府从本质意义上讲是一个公共服务与管理机构,制定政府公共政策需要按照"吸纳--化-产出"的模式进行,同时,需要相应的运行机制作保证.     

东北亚地区投资环境与投资趋向

进入新世纪以来,东北亚的投资环境发生了较大变化:在政治环境方面,朝鲜半岛局势缓和、中俄两国签署了《中俄睦邻友好合作条约》;该地区经贸关系发展迅速;东北亚日趋成为亚洲的投资重点。     

挫败“两个法国“的阴谋——二次大战期间法美关系回顾和剖析

第二次世界大战期间,美国长期和卖国投敌的维希政府维持暧昧关系,并极力排斥戴高乐,力图在法国,尤其是在法国的抵抗运动中制造分裂,推行"两个法国"的政策.戴高乐对此进行坚决反击,团结一切爱国力量,充分利用美英矛盾,争取苏联的支持,挫败了美国政府制造"两个法国"的阴谋,维护了法国的独立和主权,具有历史意义和现实意义.     

行政属性的历史流变

行政属性是流变的,而非固定如一.原始社会的行政属"前行政"阶段;古代社会和近代资本主义社会的行政,属政治行政阶段;现当代的行政则属政治与管理行政阶段;根据其流变的趋势,未来社会的行政可能属单纯的管理行政.本文还对行政流变的原因作进一步探讨.

Characterization of deletions in the DYS385 flanking region and null alleles associated with AZFc microdeletions in Koreans

Eight DYS385 allele size discrepancies and six DYS448 null types were detected among 708 Korean men when results of three in-house multiplex short tandem repeat (STR) systems were compared. The systems included both ordinary and reduced size amplicons. Sequence analysis revealed deletion mutations at two sites upstream of the DYS385 core repeats and deletion of the entire DYS448 locus. At DYS385, allele size differences were one or two repeats and were dependent on the primer set used for polymerase chain reaction (PCR) amplification. Location of the primer target sequence in a flanking region of the STR, distal or proximal to the deletion, determined allele size. Two widely used commercial kits amplify DYS385 so as to include the mutable sites. Arrangement analysis of sequence tagged sites demonstrated that the deletion patterns at DYS448 (and DYS464) were associated with arrangements of the azoospermia factor c gene (AZFc). The DYS448 deletion appears relatively frequent in Asians.     

Application of photoluminescent CdS/PAMAM nanocomposites in fingerprint detection

Uniform and well-dispersed photoluminescent semiconductor CdS (cadmium sulfide) QDs (quantum dots) were in situ prepared inside Generation 4.0-NH(2) PAMAM (polyamidoamine) dendrimers in methanol, methanol and water mixed solutions of volume ratio 1:9, respectively. The prepared solutions containing photoluminescent semiconductor CdS QDs were utilized for detection of cyanoacrylate ester fumed fingerprints on tinfoil. The results show that fumed latent fingerprints treated with prepared CdS/PAMAM nanocomposites in methanol, 1:9 methanol:water mixed solutions emit pale yellow-green and orange luminescence respectively under ultraviolet excitation of 365 nm from an UV LED. Fumed fingerprints were successfully detected with good resolving rate and the mechanism was studied in detail.

DNA polymorphism detection of Papaver somniferum L using fluorescent amplified fragment length polymorphism

OBJECTIVE: To detect DNA polymorphism of Papaver somniferum L using fluorescent Amplified Fragment Length Polymorphism. METHODS: Genomic DNA was isolated using the AxyPrep DNA Kit, double-digested by two restrictional endonucleases (Eco RI and Mse I) and ligated to oligonucleotide adapters. After Pre-amplification and selective amplification, the DNA fragments were separated by capillary electrophoresis using the CEQ8000 DNA Fragment Analyzer. RESULTS: More than 20 fragments of highly polymorphic products were obtained by 8 pairs of primer from 64 selective amplifying primer pairs. CONCLUSION: The fluorescent AFLP technique can be used to detect the DNA polymorphism of Papaver somniferum.
