    民族音乐学传播到国内后,田野调查成为研究民族音乐的一种重要方法,在此基础上出现了一批以田野调查法为指导的个案研究。从时空观上讲,无论长短,每个事物都有着自己的历史,个案事象也不例外,特别是一些具有文化遗存特征的事象更是如此。因此,个案历史研究也顺理成章的进入人们的视野。 本个案力图用民族音乐学的方法和写作形式从“区域”历史角度对洛阳十万乐进行审视。文章通过查阅相关文献先是论述了洛阳十万乐生存的社会语境并解析了洛阳十万乐的民间传说;然后对洛阳十万乐编制、音乐曲谱、传承方式、音乐曲牌以及音乐本体进行分析,试图考证洛阳十万乐是一种源自于唐代、与佛教音乐交融后在宋代流入民间、音乐主体内容多为明清时...Field work has been an important method of studying folk music when eth-muiscolgy spreaded to China.There are a lot of case studies based on Field work.From the time and space aspect, each thing has its own history regardless of their length, so dose the events based on case, especially for those who has the characteristic of culture succession. So the case study method is more and more popular. ...学位:文学硕士院系专业:艺术教育学院音乐系_音乐学学号:1872007115259

    利用唐鱼雌激素受体基因片段构建重组酵母,用以筛选环境雌激素类化学物质.实验先将唐鱼雌激素受体TErα基因片段插入载体PgAdT7中构建表达质粒P gAdT7/TErα,同时将雌激素效应元件(ErE)片段插入PMP206载体中构建报告质粒PMP206/ErE-lAC z;然后把表达质粒和报告质粒共转化到酵母AH109中,经筛选成功构建了由唐鱼雌激素受体调控的表达lAC z基因的重组酵母AHPTErα/ErE.结果表明,所构建的重组酵母AHPTErα/ErE在不同浓度17β-雌二醇(E2)的诱导下,β-半乳糖苷酶的活性呈现出明显的剂量-效应关系,其EC50为(0.521±0.700)nMOl·l-1.与dMSO对照组相比,重组酵母在17β-雌二醇诱导下有明显的β-半乳糖苷酶活性增强的现象.在不同浓度17α-乙炔基雌二醇(EE2)、壬基酚(nP)及其混合物、双酚A(bPA)、17β-雌二醇(E2)(阳性对照)的诱导下,重组酵母均呈现出剂量-效应关系,且灵敏度大小为E2>EE2>nP>bPA.结果表明,本研究成功构建了重组基因酵母测评系统,初步判定该重组酵母可应用于环境雌激素的筛选.Yeast with recombinant estrogen receptor fragment of Tanichthys albonubes( terα) was used to screen the environmental estrogen-like compounds.terα and estrogen responsive element( ere) were cloned into pGADT7 and pMP206 respectively to obtain receptor( pGADT7 / terα) and reporter( p MP206 / ERE-Lac Z) constructs.The recombinant yeast AHpTERα / ERE was obtained by co-transformation of the receptor and reporter constructs,in which the expression of lac Z is regulated by the activity of terα.The assay sensitivity was evaluated by different concentrations of 17β-estradiol( E2) treatment.The results showed that the activity of beta-galactosidase induced by E2 was dose-dependent,and was significantly higher than that of DMSO control.The EC50 of E2 was( 0.521 ± 0.700) nmol·L- 1.The assay system is also sensitive to other estrogen compounds like 17α-ethynylestradiol( EE2),Bisphenol A( BPA) and nonylphenol( NP) technical mixtures dose-dependently,and the sensitivity of different chemicals ranked as E2> EE2> NP > BPA.The results showed that recombinant yeast assay system for environmental estrogens could be applied to screen the estrogens-like compounds in the environment.广东省科技计划项目(No.20120401)~
