广东城市公用事业发展实证分析

改革开放以来,广东城市公用事业各项规模指标都有了很大程度的提高。多数行业都经历了前十年的飞速发展和后十年的低速发展。但与其他省市相比,各项城市公用事业发展具有不平衡性。城市供水、园林环卫和市政设施发展较好,城市燃气和公共交通则相对落后。从区域结构来看,广东的城市公用事业发展也不均衡。     

Developmental validation of the Microreader™ Y Prime Plus ID System: An advanced Y-STR 38-plex system for forensic applications

Y-STR is widely used in sexual assaults and familial searches of suspects. Here, we reported a novel 38-plex STR genotyping system designed for forensic applications. Microreader? Y Prime Plus ID System (YPP) amplifies 38 loci in one reaction, including 29 loci from commonly used Yfiler® Plus PCR Amplification Kit & PowerPlex® Y23 System (DYS393, DYS570, DYS19, DYS392, DYS549, Y GATA H4, DYS460, DYS458, DYS481, DYS635, DYS448, DYS533, DYS449, DYS456, DYS389I, DYS390, DYS389Ⅱ, DYS438, DYS391, DYS439, DYS437, DYS385a/b, DYS643, DYS518, DYS576, DYF387S1a/b, and DYS627), 6 commonly used loci for the Y-STR database (DYS444, DYS447, DYS596, DYF404a/b, DYS527a/b, DYS557) and one Y-indel specific for the Chinese population. YPP is designed for different types of samples, such as blood card and swabs. In this work, YPP was validated following SWGDAM guidelines (2016) and guidelines from Ministry of Public Security of the People’s Republic of China, including PCR-based, sensitivity, accuracy and precision, mixture, stability and inhibitor, and species specificity. The results indicate that the Microreader? Y Prime Plus ID System is a powerful identification kit designed for forensic databases.     

近十年来我国学界杜威思想研究述评

自1994年到2004年间我国学者在对杜威思想的研究中,撰写了大量有关杜威的教育及哲学思想的文章,其中技术哲学、传播哲学、社会哲学三个视角是近几年我国学者选取的新的切入点.从总体数量上看,我国学者有关杜威思想的文章大致呈递增趋势.这是因为,杜威对主客体的一致性的强调,同中国古代的天人合一的思维模式比较接近;杜威对行动的重要性的强调,比较接近于中国哲学注重实践的传统;杜威对民主的论述,顺应我国当今建立和谐社会的时代潮流;杜威强调的语言哲学观以及他对自然科学和人文价值的关系的格外重视,也是导致其思想复兴的主要原因;同时,美国实用主义的复兴为杜威思想在我国重新成为热点提供了契机.但我国杜威思想的研究中还存在一定问题:某些领域的研究没有进展和突破,有关杜威思想的学术译著的出版工作仍处于落后状态.因此建议:在基本理论研究方面,要深入原有的有关杜威思想问题的研究,同时,不断拓展新课题的研究,出版更多能够充分反应最新研究成果的学术论文和专著;对于杜威的著述和相关文献资料而言,可从加强杜威原著的翻译和介绍、以及加强其他人物评价杜威思想著作的翻译和介绍两个层面开展工作.     

You Can't Fix What You Don't Measure: How ALICE Can Help Rebuild the Middle Class

Seventy percent of Americans identify as middle class, but one in three middle‐income households do not earn enough to support their family at the most basic level, and four in five do not earn enough to afford a sustainable budget. This incongruity explains the increasing frustration of many workers. Yet official government measures do not capture this reality, and as a result, policy makers continue to create economic policies that perpetuate the structural mismatch between wages and costs. This Viewpoint essay addresses these shortcomings. After reviewing alternatives to the federal poverty level, it argues that the most realistic and accurate floor to the middle class is the ALICE (Asset Limited, Income Constrained, Employed) Household Survival Budget. The essay then turns to policies that help realign wages and cost of living and presents initiatives that are being implemented in states across the country. Four policy areas would enable more workers to support their families and fulfill the promise of being middle class in America: meaningful work with stable and sufficient wages, upskilling and digital retooling, fiscal cushion for periods of financial instability, and affordable credit.

论新《消费者权益保护法》规定的欺诈行为之认定

《中华人民共和国消费者权益保护法》(以下简称《消法》)自从1994年1月1日生效以来,就与人们的生活密切相关。本次修订因为规定了对经营者的惩罚性赔偿,所以备受人们瞩目。对于如何认定经营者的欺诈行为,消费者、经营者、欺诈三个词在此条中起着关键的作用,大量的争议也聚集在此三个关键词上。如果将其概念、范围用法律明确下来,那么此条解释和适用上的矛盾将会被很好的解决。     

The August 1924 raid on Stolpce,Poland, and the evolution of Soviet active intelligence

In August 1924, a Soviet-sponsored raid on the Polish town of Stolpce to free two imprisoned communist activists went badly wrong. Though the ruling Politburo had not authorized this raid, the public embarrassment and diplomatic consequences led the Soviet government to overhaul its program of ‘active intelligence’, halting peacetime attacks on neighboring states in favor of quieter preparations for wartime sabotage and diversion under the authority of the Red Army's Intelligence Directorate. At the same time, the Politburo organized stay-behind groups in Soviet border regions to prepare for the possibility of enemy occupation.
