The Analysis of Management Model of China’s and America’s Online Newspaper

为了顺应网络经济发展的时代潮流，在二十一世纪掌握传媒市场的主动权，扩大社会影响力，赢得竞争优势，国内各大报纸都积极地陆续的创建了自己的网站，以期在与网络技术的结合中取得整合效应、实现双赢。然而，我国报纸网站虽然拥有丰富的新闻资源、良好的信誉、高美誉度的品牌和国家特殊政策等方面的传统优势，但和美国的报纸网站相比，无论在受众规模、盈利能力还是在社会影响力方面都存在很大差距，显然我国报纸网站的发展现状与它作为主流新闻媒体的地位很不协调。 在我国，报纸网站的发展与互联网的发展几乎同步，同时对报纸网站的科学研究也很早就展开。随着我国报纸网站的迅速发展，与之相关的研究也逐渐增多。纵观这些文献，讨论分析偏...With the rapid development internet technology and the online population, internet, the new medium, has become a part of our daily life. Because of its quick, timely, multimedia and global characteristics in information transmission, internet is drawing more and more audience who used to take the traditional media as their main channels for information. In order to survive in the competition with ...学位：文学硕士院系专业：新闻传播学院广告学系_传播学学号：1052006115026

简述研究缘由, 回顾相关研究文献.采用多解释变量的面板数据模型, 以2000一2014年福建省九地市数据为样本进行实证分析.实证结果发现： 财政支农支出、 涉农中央一号文件、 第二和第三产业产值对农民收入有显著正向影响.据此提出转变政府职能、 完善转移支付制度、 增加财政农林水投入、 重视财政绩效评价等建议.福建省社科基地重大项目（2014JDZ048

地方财政支出结构与城乡收入差距的实证研究——基于福建省九地市相关数据

文章利用2007-2015年福建九地市面板数据,采用了泰尔指数法和空间计量模型,分析研究了政府财政支出结构对城乡收入差距的影响。实证结果为:政府财政支出及财政支出结构在一定程度上对城乡间的收入差距产生影响;其中,一般公共服务支出和支农支出的增加会扩大城乡收入差距,科教文卫支出则有利于缩小城乡收入差距,而社会保障支出对城乡收入差距没有显著影响。最后,文章在实证分析结果的基础上对缩小城乡收入差距提出相关的政策建议。福建省社科基金重大项目福建省县域财政绩效评价与公共财政制度建设研究(项目批准号:2014JDZ048)

The Dual-channel Pricing Decision-making and Quality Information Disclosure under the Information Asymmetry

探讨了质量信息不对称下制造商与零售商联合披露、制造商披露以及零售商披露3种披露方式下的双渠道定价策略,得到不同披露方式下的质量信息披露条件。结果表明:3种披露方式下的质量信息披露阈值都与披露成本、交叉价格弹性、渠道的潜在需求量相关,且披露成本越大,质量披露的动机就越小。同时借助于数值分析发现,当产品质量较低或较高时,零售商披露方式最优;当产品质量中等时,制造商披露要相对优于零售商披露,但只有联合披露可以使双渠道供应链系统达到最优状态。Under the information a symmetry of product quality,this paper discusses three quality information disclosure strategies： joint disclosure between the manufacturer and retailer,manufacturer disclosure and retailer disclosure and the pricing strategy of the dual channel. And the conditions to disclose the product quality under different quality information disclosure strategies are analyzed. Our conclusions show that the quality disclosure threshold under three disclosure formats related to disclosure cost,potential demand and the cross price elasticity,and the higher disclosure cost,the less motivation to disclosure quality. Finally,by using the numerical analysis,the obtained results show that when the product quality is low or high,it is better to adopt retailer disclosure; when product quality is medium,manufacturer disclosure is relatively better than retailer disclosure,but joint disclosure can make dual channel supply chain system reach the optimal state.国家自然科学基金项目(71571151、71371159)

长泰砂仁的本草考证及其生药鉴别

目的对长泰砂仁的品种进行本草考证及其生药鉴别。方法从本草考证、基源鉴别、性状鉴别、显微鉴别和理化鉴别等几方面来确定长泰砂仁的品种问题。结果长泰砂仁与阳春砂仁具有同一性,即是同一物种。结论长泰砂仁与阳春砂仁的化学成分含量略有差异,但主要特征成分相似,均符合国家药典规定。福建省教育厅科技项目资助课题(JA12437); 漳州市科技计划项目资助课题(Z2011060

中国东南沿海港口外轮压舱水生物的调查

随机选取东南沿海港口的17艘外来船舶(含8条集装箱船和9条散货船)作为监测对象,进行压舱水浮游植物及动物的物种鉴定和丰度测定,并对监测数据进行统计学分析。检出分属于7个浮游植物门类和5个动物门类的309种外来压舱水生物(包括60种赤潮生物)。外轮压舱水生物的分布及生存状态与水样的水龄和盐度相关。船舶压舱水排放是大家熟知的外来水生生物入侵的主要媒介。本调查结果表明,中国东南沿海外来散货船的压舱水排放所具的潜在生物入侵风险比集装箱船更应受关注

[[alternative]]Application of Ase and Isotope Dilution GC-MS for the Determination of 35 PAHs in Soil Samples

[[abstract]]A new technique for sample preparation, accelerated solvent extraction (ASE), that combines elevated temperature and pressure with liquid solvent is utilized in this study to pretreat soil samples for PAH analysis, The effects of various operational parameters (i.e. temperature, pressure, solvent type, extraction time) on the performance of ASE were investigated.The research aims at the development of a new sample pretreatment .technique for 35 polynuclear aromatic hydrocarbons (PAHs) in soil samples with GC-FID and isotope dilution GC-MS. The analytes are extracted by acetonitrile at 130℃ and 1500 psi within 5 minutes of static extraction.The time for the entire extraction process is 20 minutes.Results demonstrated that the ASE extraction is selective for PAHs.Thus, a further clean-up procedure after ASE is not necessary.The procedure of the extraction is simple and fast.ASE in recovery compared with Soxhlet extraction is higher.The results from CRM 103-100 and QCS345 analyses further vrified the high precision and accuracy of the developed analytical scheme.The result from real samples demonstrated that the concentration of PAHs in soil is low.
