The business model innovation of Shanghai Roche

创新，这是一个屡见不鲜的词，如产品创新、服务创新、制度创新。对于一个企业来说，最重要、最本质的创新是什么呢？2005年经济学人智库发起的调查中，54%的首席执行官认为，到2010年，商务模式的创新将是比产品和服务创新更重要的创新。 中国改革开放30年以来，经济环境发生了翻天覆地的巨变，中国制药企业的平台环境也因此发生了改变。制药公司竞争的顶板环境随着大量外资制药企业的进入已经不同从前，情况不容乐观。罗氏进入中国十六年来，公司的业务快速增长，规模迅猛扩张，上海罗氏制药公司内部的环境同时发生了急剧的变化。罗氏主要的客户环境更是发生了巨大的改变。所有的一切都迫使上海罗氏必须重新审视公司的发展战略以...Innovation is a popular word today, such as product innovation, service innovation, system innovation.

350-450nm范围的氧离子激发光谱的实验测量

在2×1.7串列加速器上,利用装有CCD的Spectrapro-500i光谱单色仪的测量装置,采用束-箔方法,在2 MeV束能下研究350-450 nm波长范围的离化态氧原子光谱。本文报道在350-450 nm范围已确定的182条光谱线,这些谱线大都属于O II到O IV原子的n、1能级间的跃迁的弱谱线。实验结果与现有的一些理论一致。实验发现,有28条谱线在以前的文献中没有报道

Ecological Research on Tintinnids in Tieshan Harbour,Guangxi

通过采集广西铁山港海域2010年春夏季8个站点16个样品,依据壳体形态特征对样品中砂壳纤毛虫进行了分类鉴定,对春夏季节砂壳纤毛虫的种类组成、种类的季节分布、丰度、优势种、多样性指数、均匀度指数等进行了生态学描述,并对砂壳纤毛虫群落结构与环境理化因子之间的关系进行了研究。结果表明:该海域共鉴定出砂壳纤毛虫6属15种,其中以拟铃虫属和薄铃虫属为主;春季各站点砂壳纤毛虫的平均丰度值为4 385.6Ind/M3,优势种有简单薄铃虫、诺氏薄铃虫、巴拿马网纹虫,夏季各站点砂壳纤毛虫平均丰度值为13 967.3Ind/M3,优势种有根状拟铃虫、坚果拟铃虫、简单薄铃虫、诺氏薄铃虫、妥肯丁拟铃虫;砂壳纤毛虫种类数、丰度、多样性指数和均匀度指数等均呈现夏季高于春季的总体态势,其中春季丰度呈现斑块分布,而夏季丰度则呈现出由近岸向远岸逐渐递减的趋势;聚类分析和多维尺度分析将16个站点的砂壳纤毛虫群落分为两组,春季组和夏季组,各自具有明显的季节特征;冗余分析显示,夏季溶解性有机碳、温度和总氮是影响该海域砂壳纤毛虫群落组成的主要环境理化因子,与种群数量有显著的正相关关系,而春季群落结构则受氨氮、碱度和溶解氧的影响较大。This paper investigates tintinnids in water samples taken from Tieshan Harbour sea area in Guangxi in spring and summer of 2010.Totally 15species are found,in which genera Tintinnopsis and Leprotintinnus are in dominance.In April,the average abundance of tintinnids is 4 385.6ind/m3 and the dominant species are Leprotintinnus simplex,Leprotintinnus nordqvist and Favella panamensis.In August,the average abundance of tintinnids is 13 967.3ind/m3 and the dominant species are Tintinnopsis radix,Tintinnopsis nucula,Leprotintinnus simplex, Leprotintinnus nordqvisti and Tintinnopsis tocantinensis.In this investigation,the species number,abundance,diversity and evenness in summer are higher than those in spring.The abundance distributes in patches in spring,and is higher in coastal water than in offshore water in summer.In the cluster and multidimensional scaling analysis, tintinnids community from 16stations is divided into two groups,spring group and summer group with seasonal characters respectively.Redundancy analysis reveals that DOC,temperature and TN are the main factors influencing tintinnids community composition in Tieshan Harbour sea area with great positive correlation in summer.In spring, however,ammonia nitrogen,alkalinity and dissolved oxygen have great influence on the community composition.国家自然科学基金项目(41276133、J1210050); 海湾公益项目(201005012); 海洋局专项项目(530-03-02-02-03); 厦门大学基础创新科研基金项目(中央高校基本科研业务费专项资金项目)(CXB2011020

Effects of winter mowing on community diversity and functional trait plasticity of Phragmites australis in the Yellow River Delta

Winter mowing is a common strategy for Phragmites australis management,with the effects of which on community structure and growth varying in different areas.We set two winter mowing treatments,mowing + litter removal (MN) and mowing + no litter removal (MY),to explore the effects on community diversity,community traits,individual traits and the plasticity of individual functional traits of P.australis in the Yellow River Delta,aiming to provide advice for P.australis management in this area.The results showed that winter mowing did not affect community diversity but significantly reduced plant height,stem diameter,leaf length,leaf width,leaf area,single leaf mass,total leaf mass,and total mass.Under mowing treatment,P.australis showed a trend of dwarfing but an increasing trend of abundance,resulting in stable biomass,indicating that the change of community traits may be a trade-off between individual traits and community density.Under the MN treatment,the plasticity index of individual functional traits of P.australis was higher than that under MY treatment,with relatively lower density and biomass.Considering the elimination of fire risk and the rejuvenation of P.australis,aboveground portion mowing and removal is a better management method
