“一国两制”下新闻理论与实践的政治经济基础探析

本文在阐述“一国两制“政治构想的基础上,运用马克思主义唯物史观并引入安东尼奥·葛兰西的“领导权“和卡尔·波兰尼关于自由市场经济的思想,从而尝试提出“一国两制“下新闻理论与实践的政治经济基础:即大陆地区坚持马克思主义新闻观的新闻传播体制可以与港澳台地区以私有制为主体的新闻传播体制在“一国两制“的政治制度内并行不悖,与此同时,两岸四地的传媒推动经济发展的意义重大,一方面运用新闻报道、节目合作等形式以内容不断推进交流,另一方面传媒本身所具有的不同性质和程度的经济功能使其成为经济交流的内容主体之一。国家社会科学基金重点项目《“一国两制”下的新闻理论与实践研究》(项目批号:08AXW001)的成果之

Sources，Distributions and Fluxes of Organochlorine Pesticides in Jiulong River-Estuary-Sea System

有机氯农药（organochlrinepesticides，OCPs）虽然从20世纪70年代起就陆续被禁止生产和使用，但由于使用量大，在环境中降解缓慢、滞留时间长，使得OCPs仍然是环境中检出率最高的一类POPs。水作为一种重要的环境介质，在OCPs的环境迁移和转化中起着重要的作用。目前国内外对水环境中OCPs的研究主要侧重于OCPs在水环境某一区域介质（水、沉积物、生物体）中的分布，对于系统地研究水体中OCPs从流域－河口－近海的迁移转化还是较少，此外对中国一些大江大河的OCPs入海通量的研究也较少。本文以九龙江为例，研究了九龙江流域－河口－近海水体中OCPs的相态分布特征和季节变化特征，解...Production and use of organochlrine pesticides (OCPs) have been banned in most countries since the early 1970s. Because of their used largely, persistence and semi-volatility, OCPs are still the most widly spread POPs in the environment. As an important transport medium, water bodies play an important role in the fate and occurrence of OCPs in the environment. To date, studies of OCPs in the water...学位：理学硕士院系专业：海洋与环境学院环境科学与工程系_环境科学学号：2262006115234

Research On Real Estate Private Equity Financing-A Case Study Of JJ Group

近年来，我国房地产行业的发展优势越来越明显，已然成为我国的支柱产业。作为一个资金密集型产业，其发展自然离不开强大的资金支持，这就涉及到融资环节。房地产行业中主要用到的融资渠道包括工程垫款、房屋预售、银行贷款、民间借贷、企业IPO、企业债、企业中长期票据等。目前房地产融资难的问题越来越突出，国家的宏观调控已经无法发挥该有的作用，房地产的融资环节是否顺畅将直接影响到行业的可持续发展、各个企业的命运走向、居民住房需求的满足乃至国民经济的健康稳定发展。 与此同时，大量的民间借贷涌入使得房地产行业借贷链条变得异常脆弱，如何更好地引导民间资金，避免由于资金借贷纠纷引发的社会问题，显得尤为重要。私募股权基...In recent years, China's real estate industry development advantages more and more obvious, has become a pillar industry in China. As a capital-intensive industry, and its development is inseparable from the natural strong financial support, which involves financing aspects.

电视新闻收视率:质量为王——美国地方电视新闻质量危机调查报告

美国的地方电视新闻已经走到了十字路口。观众正在放弃传统媒体,更多地转向了因特网。正如10年前,有线电视的出现导致电视新闻网失去了大量的观众一样。然而电视工业对此所做出的反应却使它走上了一条致命的错误之路。一项针对美国地方电视台新闻的研究揭示出这样一种情况:现在地方电视台新闻节目的经营方

The Application of Polyimide(PI) in the Manufacture Process of RF MEMS Capacitive Shunt Switch

聚酰亚胺树脂(PI)因其良好的平面化特性、在氧气中易灰化、不完全固化易溶解于碱性显影液、在CHF3等离子气氛中有较强的抗蚀性等性质,在电容RFMEMS开关的制作过程中,应用它作为刻蚀保护层和牺牲层,不但可以使工艺过程得到简化,而且可以对开关的介质层尺寸、牺牲层厚度等图形参数起到很好的控制作用.As a kind of polymer material, polyimide(PI) holds a favorable complanation property and is easy to become ash in the oxygen.PI also can resist ion etching produced by the CHF_3 plasma body and be easy to dissolve in alkali developer solution when it is not solidified completely.Basised on the properties mentioned above,PI can be used in the manufacture process of RF MEMS Capacitive Shunt Switch to achieve a precisely control on the size of dielectric layer,the thickness of sacrificial layer and some other graph parameters

Distributions of dissolved organochlorine pesticides and polychlorinated biphenyls in China coastal waters

分析调查了中国部分海域海水中溶解态有机氯农药(OCPS,25种)和多氯联苯(PCbS,6种)的残留分布特征。结果表明,所有采样点都不同程度地受到了OCPS和PCbS的污染,其中福建省福州平潭和莆田湄洲岛的OCPS污染较为严重,浓度分别达到1752.59和796.19 ng/l;而辽宁省的大连老虎滩OCPS污染较轻,浓度为53.63 ng/l。各采样点海域海水中HCHS污染程度一般高于ddTS,HCHS主要以早期残留为主;根据ddT/ddTS的比值推测,在福州平潭、莆田湄洲岛和珠海淇澳岛水体显示有新的ddT输入。在各海域水体中溶解态PCbS的浓度为33.55--474.92 ng/l,均超过了美国环保局规定的海水浓度限值。因此目前我国沿海海域水体中持久性有机污染物有机氯农药和多氯联苯污染仍不能忽视。The concentrations of organochlorine pesticides(OCPs,25) and polychlorinated biphenyls(PCBs,6) in seawater collected from China coast were investigated.The results showed that concentrations of OCPs ranged from 53.63 to 1752.59 ng/L in seawater,and the highest value was in Pingtan(Fuzhou) while the lowest value was in Laohutan(Dalian,Liaoling province).At all of sampling sites,the concentrations of DDTs and HCHs were lower than the limits of national seawater quality standards(class 1),and the concentration of HCHs was higher than that of DDTs.The ratios of DDT/DDTs showed new DDT into Pingtan(Fuzhou),Meizhoudao(Putian) and Qi'aodao(Zhuhai,Guangdong Province),whereas the isomers characteristics for HCHs showed the residues at all sampling sites.The concentrations of dissolved PCBs ranged from 33.55 to 474.92 ng/L in seawater,which were higher than the limit of EPA seawater quality standard.However,the occurrence of OCPs and PCBs in seawater along China coast should be concerned.国家自然科学基金(40476048;20777060);厦门大学新世纪优秀人才计划基
