    从20世纪90年代至今,中国卫浴行业经历了近30年的发展,已经成为全球最 大的卫浴产品生产和销售国,卫浴洁具占世界总销售额的30%,卫浴配件约占世界 总销售额的35%,但由于本土企业以及外来品牌之间的激烈竞争,国内的卫浴企业 大多在中低端市场上竞争,利润微薄。从出口来看,国内卫浴企业主要面临三个方 面的挑战:一是出口目标市场发生转变,欧美国家需求下降,但新型国家需求旺盛; 二是卫浴竞争的策略发生了变化,卫浴企业已走出粗放型的经营模式,开始向创新 和品牌路线转变;三是客户需求发生了质的转变,客户趋向购买绿色、智能且融合 化的卫浴产品。在这种形势下,我国卫浴企业应加快企业调整,自我完...From the 1990s till now, China's bathroom industry has experienced around 30 years of development.

    网上银行业务在我国各商业银行已经展开,但是国内法律法规及金融规章并未对这一新业务进行系统规制。网上银行业务由于其本身所具有的高技术性、无纸性、瞬时性等特点,使其所涉法律问题甚为丰富而复杂。与网上银行业务有关的法律问题对传统的法制和理念提出了挑战。本文关注网上银行的发展,尤其是网上银行业务有关的法律问题。本文共三部分,即前言、正文和结论。其中正文又分四章。第一章介绍网上银行的定义和网上银行业务及其特点。第二章分析网上银行业务所蕴藏的风险种类及其特征。第三章为完善我国网上银行业务有关立法的思考。主要是论述了完善我国网上银行业务有关法律制度的必要性和紧迫性,从网上银行业务有关立法的基本原则和网上银行...The internet bank operation has been outspread in our country’s commercial banks. But the domestic laws, rules and financial regulations haven’t stipulated and restrict the operation systematically. The internet bank operation has the characteristics of high technicality, none-paper, instantaneousness, which makes its legal problems rather abundant and complicated.

    Idealized Self-Presentation and Gender Stereotypes of Dating Website’s Users——Illustrated By the Case of Jiayuan.com

    Get PDF
    近年,专门提供婚恋交友服务的婚恋网站成为许多现代青年男女婚恋交友的重要平台。婚恋网站为用户提供了一个向潜在婚恋伴侣呈现自我的舞台。戈夫曼的自我呈现理论指出,人们总是倾向于向他人展示一个理想化的自我形象。这种倾向在婚恋交友中表现尤为突出。 在自我呈现的过程中,用户需要考虑:在他人眼中,怎样的自我形象才是有吸引力的。这种形象往往符合社会所公认的男性或女性应具备的性别特征,比如要具备怎样的性别气质,承担怎样的社会角色等。因此,用户要呈现怎样的自我形象,要在哪些方面进行理想化的呈现,与其社会性别观念有着千丝万缕的关系。 本文以世纪佳缘网站为例,通过分析用户在其个人页面所呈现的自我形象及其理想化的表...In recent years, online dating sites which are specialized in online dating service become good choice for many modern young men and women. Dating website provides users with a stage to present themselves to potential spouse. The self-presentation theory of Goffman points out that people always tend to present an idealized image of themselves to others. This tendency is especially outstanding in o...学位:文学硕士院系专业:新闻传播学院_传播学学号:3192012115280

    诗人许浑生卒年新说及晚唐两许浑考辨

    Get PDF
    诗人许浑的生卒年有生于贞元四年卒于咸通二年或稍后的新说。但这种新说的根据尚需认真考辨。张祜诗中的"五十我无闻"句中之"我"乃自指,"五十"非指许浑的年龄,不能以此推出许浑的生年;而顾陶的《唐诗类选后序》作于大中十年而非约咸通三年前后,故不能以此文撰于咸通三年前后论断许浑、杜牧等人的卒年;考订《新唐书.宣宗纪》,认为其中刘皋被杀于大中十二年三月的时间记载有误,故不能据此而论定许浑卒于大中十二年三月之后;《吴越备史》中的侍御史、卫尉卿许浑,并非诗人许浑;晚唐有两许浑,不能将侍御史许浑的事迹作为考证诗人许浑卒年的考证依据

    许浑卒于“咸通二年或稍后”说辨误——兼答罗时进君

    Get PDF
    张祜之卒约在大中十三年(859),如至咸通十一年(870)才十二年虚,到咸通十三年才十四年虚,均远不能称“未二十年“。此即可证《后序》非“咸通三年前后“撰,反之可证张祜大中八年卒可信。张祜既卒于大中八年、杜牧大中六年底卒,二人去世均在大中十年前,而《后序》谓包括两人在内诸人之卒至《后序》撰时“才二、三年“,则《后序》大中十年作又再得确证。《唐诗类选后序》若撰于大中十年,则诗人许浑与侍御史许浑并非一人。如此,罗时进君的诗人许浑“咸通二年或稍后“卒的观点不能成立

    福建省高校新闻传播本科教育的发展现状、问题及对策研究

    Get PDF
    就业形势的严峻性、经济全球化和以社交媒体为代表的新媒体的迅猛发展,对新闻传播专业人才提出了新的要求。如何适应当前传媒业乃至整个社会的人才需要,成为了新闻传播学教育者必须思考的议题。本文选择了福建省三所学院作为研究个案,通过对行政管理者、教师和学生的深度访谈,考量福建省高校新闻传播本科教育的发展现状、问题及对策。调研发现,三所学院的本科生培养兼顾专业特点和地方特色,形成了新闻传播本科教育的“福建模式“;当前,这一模式面临诸多挑战;三所学院或着眼局部调整,或酝酿整体改革,后者仍处于探索阶段,但有望为福建省乃至全国的新闻传播院系应对当前挑战提供全新视角。福建省教育科学“十二五”规划一般项目“福建省高校新闻传播学本科教育的创新性发展研究”的成

    对韭开花前1 d到开花后2 d的发育胚囊中CA2+分布特征进行研究,结果显示:在开花前1 d游离核胚囊形成细胞,CA2+主要分布在极核周围的细胞质小液泡中,与中央细胞的大液泡形成有关;在开花当天,卵细胞大液泡体中CA2+增多,与其大液泡形成有关;开花后1 d,卵细胞大液泡中钙沉淀颗粒减少,助细胞珠孔段的CA2+增多,合点端较少,呈极性分布;开花后2 d,卵细胞大液泡和中央细胞大液泡珠孔部位CA2+再次明显增加。助细胞珠孔端丝状器中CA2+也增加,一个助细胞退化,呈现接受花粉管状态。韭发育胚囊中CA2+分布特征显示其参与调控胚囊细胞的分化,揭示雌配子体中CA2+分布的时空特征是深入研究胚囊细胞分化的基础。Characteristic of Ca2+ distribution in developing female gametophyte of Allium tuberosum was studied from 1 d before anthesis to 2 d a fter anthesis.At 1 d before anthesis, the nuclear embryo sac differentiates gametophyte cells.Calcium precipitates of young embryo sac were few and mainly located in the small vacuoles surrounding polar nuclei, suggesting Ca2+ relating with the formation of the large vacuole of central cell.At anthesis, the precipitates in large vacuole of egg increased, also suggesting Ca2+ relating with formation of the large vacuole of egg cell.At 1 d after anthesis, the precipitates in egg cell decreased and increased in synergid cells, in which the precipitates displayed polarity distribution: more in the micropyle end of the cell than in the chalazal end.At 2 d after anthesis, the precipitates in the large vacuole of egg and the micropyle part of central cell appeared again.The precipitates in filiform apparatus of both synergids also increased.One synergid cell degenerated, which prepared to accept pollen tube.The characteristic of calcium distribution in developing embryo sac of A.tuberosum suggests that Ca2+ may regulate cell differentiation of embryo sac.Exploring the spatial-temporal feature of Ca2+distribution in developing embryo sac is a base of further study of cell differentiation of embryo sac.国家自然科学基金(31170289); 公益性行业(农业)科研专项课题(200903016

    目的利用响应面法对潜在的Tnf-α抑制剂桥南霉素固态发酵培养基进行优化。方法用HPlC做检测方法,以桥南霉素的洗脱峰面积为指标,先通过PlACkETT-burMAn(P-b)实验筛选出影响固态发酵产量的主要因素,进而进行单因素优化实验和响应面中心组合设计实验,确定主要影响因素的最佳浓度,得到最优的固体发酵培养基组成。结果优化后的发酵培养基组成:土豆400g/l、葡萄糖35g/l、蛋白胨10.5g/l、(nH4)2SO4 0.6g/l。按此配方固态发酵10l,对得到的粗提物进行HPlC检测,桥南霉素的实际产量为4.3Mg/l,与模型的理论值基本相符,较优化前的产量1.5Mg/l提高了186.7%。结论响应面方法是一种有效的培养基优化方法,经此优化方法桥南霉素的产量得到了较大的提高。Objective The solid fermentation culture conditions of compound qiaonanmycin were optimized via response surface methodology.Methods Based on quantitative detection method of qiaonanmycin by HPLC, the key fermentation factors were determined via P-B test, then their optimized concentrations were confirmed through response face method.Results The optimum solid fermentation culture medium compositions of qiaonanmycin were: potato 400g/L, dextrose 35g/L, peptone 10.5g/L, and(NH4)2SO4 0.6g/L.Under this condition, the yield of qiaonanmycin was 4.3mg/L, resulting in a 186.7% increase comparing with original production yield, and the optimized yield was consistent well with theoretical value predicted by response face method.Conclusion The optimized solid fermentation culture conditions were reliable and repeatable, it was warranted for large-scale fermentation process.中央高校基本业务费(No.2010121092); 厦门市科技计划项目(No.3502Z20123010
