Preliminary Studies on Allelopathic Potentials of Spartina alterniflora on Mangrove plants

本文研究了不同质量浓度互花米草水浸液(SAAE)对白菜、黄瓜和萝卜种子萌发和幼苗生长的影响，系统评价其化感潜力；同时研究了不同质量浓度SAAE对桐花树、白骨壤和木榄幼苗生长的影响以及不同密度互花米草与秋茄混种对秋茄幼苗生长、光合特性、渗透调节物质和氧化抗氧化系统变化的规律。结果表明： 1.不同浓度SAAE对白菜、黄瓜和萝卜种子萌发的速度均有影响；除了部分低浓度SAAE对受体植物的苗高生长具有促进作用外，其余各浓度对受体植物苗高和根系的生长均产生抑制作用，且随着浓度的升高抑制作用增强；其中0.4g·ml-1地上部分水浸液和0.5g·ml-1地下部分水浸液对受体植物的苗高和根系的生长抑制作用最强...Abstract This paper evaluated systematically the potential of allelopathy for Spartina alterniflora by treating with different concentrations of S. alterniflora aqueous extracts (SAAE) on cabbage, cucumber, and radish.

Design and Implementation of Collaborative Office Management Platform of Wenshan Prefecture

企业在不断发展的过程，由于信息的流通性不强，企业各部门协作能力差，在加上企业的工程企业分为若干个子公司，更突出了消息闭塞，协作性差，办公效率不高，企业办事的审批效率差等因素，企业很大一部分业务需要人工来统计数据，在统计后的数据的基础上再进行制定经营策略，效率和失效性都很差，在如今的社会，更晚制定出经营策略意味损失更多的利益承担更大的风险。 针对上述问题以及文山州日常办公管理的实际情况，本文以电子政务信息的管理为背景，提出了一套给予B/S架构的文山州协同办公管理平台系统，并详细阐述了该系统的设计与实现。本系统以WindowsServer2003为网络操作系统，以C#作为开发语言，以SQLSer...During the development of enterprise, which human resource is quite reliable to collect the data due to bad communications and coordination between departments, and furthermore the engineering enterprise split into several subsidizes.

The Existing Problems and Countermeasures of Xiamen’s Unemployment Insurance

失业保险制度作为社会保险领域的五个项目之一，是指国家通过制定法律强制实行的，集中全社会的力量建立专项基金，对劳动年龄内非因个人原因而失去工作，导致暂时缺少生活来源的劳动者在特定时期内发放一定的物质资助并帮他实现再就业的一种社会保险制度。它对于稳定社会，促进经济的发展，发挥了非常重要的作用。但随着我国社会的发展和经济体制改革的步伐加快，现行的失业保险体制出现了一些问题，不能满足社会发展的需要。在这种形势下，不断地完善和健全失业保险制度，对于缓解一直在增强的就业现象来说，显得特别的重要和紧迫。 本文正是基于这个原因，在失业保险制度一般理论的框架下，通过文献的查阅、分析，学习和借鉴了国内外失业保险...Unemployment insurance system is one of the main items of social insurance. It is enforced by the national legislations, accumulated by the community and at the same time temporarily providing material help for those who belongs to workers group but lost their jobs because of other reasons and thus safeguarding their basic lives and finally realizing their re-employments. It has played a very im...学位：公共管理硕士院系专业：公共事务学院_公共管理硕士学号：X201113600

The Research on Insurance Capacity of Catastrophe Risks in China’s Property Insurance

中国作为世界上自然灾害最为严重的国家之一，长期以来一直遭受着各类巨灾风险带来的巨大损失。自上世纪九十年代以来，中国因为巨灾造成的直接经济损失呈逐渐上升趋势。据民政部统计资料显示，近十年来，中国每年因自然灾害造成的直接经济损失都在千亿元以上，常年受灾人口达两亿多人次。 中国巨灾风险所造成的经济损失整体上呈上升趋势，这也与全球巨灾风险的经济损失一致。然而，中国的巨灾保险却远远落后于保险业相对成熟的国家和地区，同时也与中国的经济发展现状以及巨灾保险需求难以匹配。国际上巨灾保险对灾害损失的补偿达到百分之三十至百分之四十，但我国这一比例不到百分之一，其中汶川大地震时的保险赔付占比仅百分之零点二。如果建...China has suffered from enormous losses brought by all kinds of catastrophes for a long time. The direct economic loss caused by the catastrophe was gradually rising in China since the 1990s. Over the past decade, China's annual direct economic losses caused by natural disasters are more than a hundred of billions and more than two hundred million people were affected. Economic losses caused by c...学位：经济学硕士院系专业：经济学院_保险学学号：1562011115199

关于我国建立环境责任保险制度的再思考

近来全国范围内的空气污染、雾霾天气,使治理环境污染成为今年两会的热点话题,建立实质意义上的环境责任保险制度迫在眉睫。由于环境责任保险具有技术要求高、赔偿责任大等特点,以及我国相关的立法不完善、制度的缺失、保险公司分散自身风险渠道不足和国内保险公司的学习精神不足等问题,造成我国环境责任保险虽有试点推出,但自身却发展不够理想。本文通过分析环境责任保险在我国的发展现状及掣肘原因,结合国外的优势经验,进而探讨我国环境责任保险制度建立的可行性和必要性

A Novel hepcidin-like Antimicrobial Peptide Isolated from the Japanese Bass(Lateolabrax japonicus Cuvier et Valenciennes)

利用分子生物学技术,从我国海水养殖鲈鱼(Lateolabraxjaponicus)分离到一种hepcidin抗菌肽新基因,并在国际GenBank公布(accessionnumber为AY547281).初步研究结果表明,在我国鲈鱼分离到的hepcidin基因属于hep cidin抗菌肽基因家族的新成员.A novel hepcidin-like antimicrobial peptide gene was isolated from the liver RNA of the Japanese bass(Lateolabrax japonicus) following bacterial challenge. Sequencing analysis of the novel hepcidin-like antimicrobial peptide showed that it shared eight cysteines at conserved positions identical to the human hepcidins and the hybrid striped bass(Morone chrysops×M.saxatilis) hepcidin. Peptide sequence and the predicted gene organization of the preprohepcidin were similar to that reported from the hybrid striped bass and human. A predicted 88-residue hepcidin prepropeptide consists of three domains: a signal peptide(24 amino acids), a prodomain (43 amino acids),and a mature peptide(21 amino acids). In contrast to the human and bass hepcidins,there were around 8 and 5 amino acids different in the predicted mature peptide,respectively.The pioneer research indicated that the hepcidin from the Japanese bass was the homologue of the hybrid striped bass and human hepcidins, meaning that a new member of the hepcidin family was discovered.福建省重大科技项目 (2 0 0 3I0 0 5);; 厦门市高新技术项目 (3 50 2Z2 0 0 2 1 0 52

An Empirical Analysis of China Price Transmission Mechanism After 2008 Financial Crisis

本文采用扩展SOP模型的方法,分析金融危机发生以来我国rMPI、PPI、CgPI和CPI物价传导机制的特征。结果发现,生产环节的PPI对上游投入环节的rMPI和下游批发环节的CgPI传导不畅,生产厂商在价格传递链处于夹心地位;金融危机后,消费环节的CPI不能回馈传导上游的任何环节,居民的需求拉动能力和作用发挥不明显。The post-financial crisis price transmission mechanism between RMPI,PPI,CGPI,and CPI is investigated by using extended stage of processing model.The empirical evidence shows that,changes in RMPI transmit to PPI,not vice versa,and PPI response to the changes in CGPI.After the financial crisis,the changes in CPI do not feedback to any stage in the price chain,the consumer demand is not the key factor in driving prices.国家社会科学基金资助项目(09CJY013;11CJY098); 中央高校基本科研业务费专项资金资助项目(2014ZM0082;2014GD03
