Living the City Dream

When she obtained her master's degree this year, Zhu Yanyan decided to leave Beijing after residing in the capital for six years and go back to her hometown in Chengdu, Sichuan Province, to settle down. Compared with Beijing or Shanghai, the cost of living in Chengdu is lower, making life less stressful—but no less convenient, Zhu explained.     

From Passive Actor to Active Leader

The closing ceremony of the Fourth China International Import Expo (CIIE) took place in Shanghai on November 10. As the world's first dedicated import exhibition at the national level, the CIIE serves as an important platform for international purchasing, investment promotion, cultural exchanges and cooperation. The Fourth CIIE coincided with the 20th anniversary of China's accession to the World Trade Organization (WTO). The past two decades have seen China's economic aggregate jump from about 10 trillion yuan ($1.54 trillion) in 2001, to more than 100 trillion yuan ($15.4 trillion) in 2020, while its total foreign trade leapt to $4.6 trillion from $500 billion during the same period.     

侨资与福建农村经济高质量发展的互动关系研究

基于华侨华人具备投资福建农村的三大优势,在侨资受内资和纯外资双重压力及福建农村的有限资源约束背景下,侨资与福建农村经济高质量发展之间存在动态影响.在构建福建农村经济高质量发展指标体系的基础上,测算了福建农村经济高质量发展指数,并运用EG检验、脉冲响应、方差分解等方法,实证结果发现,短期内侨资对福建农村高质量发展的贡献较大;长期来看,福建农村经济发展对侨资的吸引力逐渐增强,甚至超过侨资对福建农村经济发展的作用,福建农村高质量发展对侨资的推动作用时限更长.主要原因在于短期内侨资的逐利性发挥了重要作用;从长期来看,福建农村高质量发展仍能有效促进资本的集聚,吸引不同类型的资本投资,促使农村产业结构得到优化.     

Evaluating the forensic informativeness of mtDNA haplogroup H sub-typing on a Eurasian scale

The impact of phylogeographic information on mtDNA forensics has been limited to the quality control of published sequences and databases. In this work we use the information already available on Eurasian mtDNA phylogeography to guide the choice of coding-region SNPs for haplogroup H. This sub-typing is particularly important in forensics since, even when sequencing both HVRI and HVRII, the discriminating power is low in some Eurasian populations. We show that a small set (eight) of coding-region SNPs resolves a substantial proportion of the identical haplotypes, as defined by control-region variation alone. Moreover, this SNP set, while substantially increasing the discriminating efficiency in most Eurasian populations by roughly equal amounts, discloses population-specific profiles.     

A motion detection-based framework for improving image quality of CCTV security systems

Closed-circuit television (CCTV) security systems have been widely used in banks, convenience stores, and other facilities. They are useful to deter crime and depict criminal activity. However, CCTV cameras that provide an overview of a monitored region can be useful for criminal investigation but sometimes can also be used for object identification (e.g., vehicle numbers, persons, etc.). In this paper, we propose a framework for improving the image quality of CCTV security systems. This framework is based upon motion detection technology. There are two cameras in the framework: one camera (camera A) is fixed focus with a zoom lens for moving-object detection, and the other one (camera B) is variable focus with an auto-zoom lens to capture higher resolution images of the objects of interest. When camera A detects a moving object in the monitored area, camera B, driven by an auto-zoom focus control algorithm, will take a higher resolution image of the object of interest. Experimental results show that the proposed framework can improve the likelihood that images obtained from stationary unattended CCTV cameras are sufficient to enable law enforcement officials to identify suspects and other objects of interest.     

关于当代中国社会矛盾的几点认识

当代中国社会基本矛盾的具体表现形式是效率与公平、"市场"与"计划"的矛盾。矛盾的产生是不可避免的,因此对待矛盾的正确态度不是试图一劳永逸地消除它们,而是在具体的历史情境中不断地解决它们。解决矛盾需要有正确的方式,正确方式的选择取决于对当代中国社会矛盾特点的把握,效率、公平、市场、计划分别来看, 都是社会发展追求的目标,联系在一起却相互矛盾,这就是当代中国社会矛盾的基本特点。对这样的矛盾,正确的解决方式不是一方克服"吃掉"另一方或矛盾双方"同归于尽",而是"矛盾双方并存"或"矛盾双方在相互博弈过程中融合成一个新事物"。这种方式在当代社会生活中的对象化形式即是民主和法治。     

执政能力建设的基础工程——用发展着的马克思主义理论武装全党

马克思主义理论对提高党的执政能力具有多方面的意义.党的十六届四中全会<决定>对加强马克思主义理论的学习、研究和宣传,出了总题目,提出了新要求.必须用发展着的马克思主义理论武装全党,着力解决世界观、方法论、历史观、经济学诸方面的问题,特别是抓好中央决定进行的"马克思主义理论研究和建设工程",编出有鲜明创新性和充分说服力的理论教材.目前的理论教育中存在着不钻研马克思主义基本原理和不结合工作实际特别是思想实际的倾向,需要在新的条件下重提"改造我们的学习".
