A Study on the Security Challenges of 21st-Century Maritime Silk Road

“海上丝绸之路”是古代中国与沿线国家开展贸易和文化交往的海上通道，推进了世界文明的繁荣发展，是联系沿线国家的桥梁。2013年10月3日，习近平主席访问印尼期间，提出愿与东盟国家加强海洋合作，发展好海洋合作伙伴关系，共同建设“21世纪海上丝绸之路”（以下简称“新海丝”）的重大倡议，引起了国内外的关注。中国旨在借用古代“丝绸之路”这一历史符号，秉持和平合作、开放包容、互学互鉴、互利共赢的理念，全方位推进务实合作，加强沿线国家之间的互联互通，主动发展与沿线国家的经济合作伙伴关系和人文交流，从而打造共同打造政治互信、经济融合、文化包容的利益共同体、命运共同体和责任共同体。 新海丝以海上突破统领东稳、...As the maritime route of trade and cultural exchanges ,Maritime Silk Road promoted the progress of human civilization,and contributed greatly to the prosperity and development of the countries along the Maritime Silk Road.When Chinese President Xi Jinping visited Indonesia in October 3 of 2013, he raised the initiative of jointly building the the 21st-Century Maritime Silk Road , which have attra...学位：法学硕士院系专业：南洋研究院_国际关系学号：2552013115227

pH-Responsive Dendritic Polyrotaxane drug-polymer conjugates forming nanoparticles as efficient drug delivery system for cancer therapy

本文研究了具有超支化结构的聚轮烷-阿霉素药物载体的制备及其抗肿瘤作用。通过一系列的化学反应及环糊精与PEG的主客体自组装过程方法成功制备了pH敏感的阿霉素药物偶联载体,实验结果表明该制备方法具有分子量可控,分子量分布窄,载药量固定等优点,且合成的药物载体生物相容性较好。通过动态光散射(DLS)及透射电镜(TEM)发现,该药物载体可以在水溶液中进一步自组装形成粒径在100 nm左右的均一纳米粒子。体外释放研究表明,由于药物阿霉素是通过酸敏感的腙键与聚轮烷相连,药物阿霉素在pH=6及pH=5的释放情况下明显快于人体血液生理pH=7.4的释放情况,达到了刺激响应性释放的目的。体外研究表明,该药物偶联..

GABPA inhibits invasion and metastasis of Hepatocellular Carcinoma

肝细胞癌（Hepatocellularcarcinoma，HCC）已经成为危害人类健康的重要杀手，其发病率在全球病例数中位于第五，而导致的死亡率居于第三位。肝癌以高转移、高复发、愈后差、死亡率高为特点，但目前对其高转移、高复发的分子机制研究的还不很清楚。最近研究表明GABPA的异常表达与肝癌的发生发展相关，但其生物学功能、临床病理意义及相关的分子机制仍不清楚。 在本课题中，我们用RT-PCR、WB的方法分别检测了临床肝细胞癌病人组织中GABPA的mRNA和蛋白表达情况，分析GABPA与临床病理及预后的关系。接着我们构建了GABPA的过表达、敲低稳转细胞系，采用transwell、划痕等方法探...Hepatocellular carcinoma (HCC), one of the most important killers of human health, is the fifth in the incidence of the number of cases in the global number of malignant tumors and the third of resulting mortality rate of tumor-related death. Liver cancer is characterized by high metastatic, high recurrence, poor prognosis, and high mortality. However, the molecular mechanism of high metastatic a...学位：理学硕士院系专业：医学院_微生物学学号：2452014115348

CEO Overconfidence and Corporate Investment：A Study on IPO Over-funding of Chinese SME and GEM Board Listed Companies

传统财务学理论认为，管理者基于股东价值最大化的目标进行财务决策，造成财务决策差异的原因在于公司、行业、市场等特征的不同。现代财务学研究还进一步注意到，信息不对称、代理问题及制度环境也会对财务决策产生影响。然而，尽管这些因素十分重要，但仍然并未能解释财务决策的全部差异，它们都难以清晰解释同一公司不同时期的财务政策所具有的粘性以及具有类似特征的公司在财务决策上表现出来的显著差异。另一方面，管理实践和研究证据发现，管理者个人对公司决策具有十分关键的影响。因此，管理者个人特质被引入财务学研究，并于近年来不断拓展，成为学术界关注的一个重要课题。 在管理者个人特质与公司财务决策之间关系的研究中，管理者的...Over the past decades, the overconfidence has been discussed and studied in depth by academics. The studies essentially fall into two directions: the one takes the perspective of behavioral finance, which suggests that overconfidence is a kind of psychological bias, and that the overconfident would seem too optimistic in estimation of individual abilities, access to information and future developm...学位：管理学硕士院系专业：管理学院_财务学学号：3212012115057

Research on acoustic characteristics and acoustical culture for large yellow croaker

大黄鱼是我国特有的优质、高值经济鱼类，是目前中国网箱养殖的主要鱼类之一。近年来，随着海洋运输、港口建设、水下爆破工程作业等日益频繁，浅海网箱养殖环境日益恶化，大黄鱼养殖出现死亡率高、生长缓慢、成熟个体小型化、抗逆性差的种质退化现象，严重制约了大黄鱼养殖业的健康发展。本课题拟从鱼类声学角度出发，深入分析大黄鱼的声学特性，探索在开放海域中开展大黄鱼声学驯养的方法，有效改善大黄鱼种群质量，为大黄鱼养殖提供一种更加健康、高效和安全的生产模式。 研究主要内容： 1、采用水下光学、声学相结合的监测手段，应用短时傅立叶变换、连续小波变换等时频联合分析的信号处理方法提取大黄鱼发声信号参数，研究不同成长阶段...Large yellow croaker is a kind of high-quality, high-value fish, and is one of the major cage-cultured fish in China. In recent years, with the rapid development of the marine transportation, port construction and underwater engineering, the cage-cultured environment in shallow sea is increasing deterioration. As a result, The genetical characterization decline of cage-cultured large yellow croake...学位：博士后院系专业：海洋与环境学院环境科学与工程系_环境科学学号：201017005

Comparison of the determination of TP and TN using national seawater method and surface water method

应用国家的海水分析方法(流动注射分析法)和地表水分析方法测定珠江口不同盐度的海水样品中的总磷和总氮,分别进行精密度试验和准确度试验,并对两种国标方法进行比较。实验结果表明,两种方法无显著性差异。流动注射法适用于任何盐度海水中总磷和总氮的测定,且方法具有检出限低、环保、高效等优点。The concentrations of total phosphorus( TP) and nitrogen( TN) in different salinity samples in Pearl River estuary were determined by using national seawater analytical method and surface water analytical method,respectively. The accuracy and precision of the two methods were investigated,and the concentrations of TN and TP in different salinity were compared by using the two methods. The experimental results indicated that the two methods showed no significant difference. But the seawater analytical method by using flow injection( FI) showed lower detection limit,more environment friendly and higher efficiency than that of the surface water analytical method.国家海洋局环保司2011年度《珠江口海洋环境质量综合评价方法》(DOMEP(MEA)-03-01);; 国家自然科学基金青年基金(41406093);; 广东省教育厅科技创新项目(2013KJCX0103);; 广东省科技计划项目(2013B090600033

Study on Acoustic Scattering Characteristics of Fish and Monitor System for Bred Fish in Offshore Fish Cage

深水网箱养殖因其抗风浪、耐海流能力强、养殖容量大、高产高效、环保等优点成为目前国内外海洋水产养殖业可持续发展的必然趋势。然而，与传统网箱养殖比较，深水网箱养殖由于网箱所处水域深、鱼群活动空间大，肉眼不容易观察到网箱内鱼群的活动及网衣安全状态，一旦发生逃鱼，经济损失巨大。因此，如何对网衣安全、网箱内鱼群生长情况、鱼群量变化进行日常监测，当发现网衣破损、鱼群逃逸等异常状况时及时报警是深水网箱养殖推广过程中急需解决的一项关键技术。本文针对深水网箱养殖中急需解决的鱼群安全问题，开展了鱼类声学散射特性和鱼群量估计算法研究，设计并实现了一套深水网箱鱼群状态远程、实时声学监测系统。 论文主要内容： 1、...For its advantages of strong resistance to wind waves and tidal current, large breeding capacity, high efficiency and environmental protection, fish culturing in offshore fish cage becomes the developing trend of sustainable marine aquaculture industry at home and abroad.

从先师到德育家 : 《教育世界》时期罗振玉的孔子观及日本影响

Late Qing Dynasty, with the end of traditional feudal education and imperial examination system, western-style education reform had become an inevitable trend, and the status of Confucius, the former sacred tutor, inevitably declined. As a pioneer of education reform, Luo Zhenyu had to rethink Confucius' position in culture and education. By learning from Japanese educational experience and research works, Luo completed the transformation of Confucius from a traditional "Xian Shi" to a modern moral educator. He combined the "expert" Confucius with the "sage" Confucius, so that Confucius not only retained the traditional respect, but also obtained the modern identity to adapt to the trend.内田慶市教授古稀記念号departmental bulletin pape
