The application of fair value valuation model in account receivable factoring
应收账款本质上属于企业的金融资产,其流动性的高低一直是提高企业资产质量,提升企业盈利变现能力的关键。在解决金融资产的流动性问题,加快金融工具创新的过程中,开展无追索权应收账款保理业务以实现金融资产的转移、变现,成为企业改善现金流,优化资产结构的有效途径。 公允价值在金融资产转移定价中有着非常突出的作用。对于金融资产而言,公允价值是最相关的计量属性,特别是对于衍生金融产品工具而言更是唯一相关的计量属性。虽然我国会计准则引入了公允价值计量的使用,但在实务操作中对于公允价值的确定及估值方法却缺乏可操作性,因此金融资产的公允价值难以科学、有效地确定。本论文通过采用公允价值估值模型确定应收账款保理业务...Accounts receivable, as an enterprise's financial assets, their liquidity level is the key to improve enterprises’ assets quality and profit cashability. In solving the liquidity of financial assets, to speed up the process of financial tool innovation, by developing nonrecourse accounts receivable factoring realize the transfer of financial assets, cash, become the enterprise to improve cash flow...学位:会计硕士院系专业:管理学院_会计学学号:X201115705
Research on the Marketing Strategy for S Steel Trading Company
钢铁产业是国民经济重要的基础产业,是一个国家生存及发展的重要物质保障。受2008年全球金融危机的影响,中国钢铁产业虽然产量逐年上升,而市场需求却严重萎缩,产能严重过剩,钢材价格大幅度下跌,行业经济效益明显下滑,加上一些钢贸企业恶意融资,引发行业信用危机,导致运转资金匮乏,整个钢铁行业的发展受到了前所未有的挑战。作为一家私营的钢贸企业,S公司如何进行营销策略的创新,如何铸造具有竞争力的发展路径迎难而上,这成为公司管理层亟需解决的问题。 基于此,本文采用文献研究法和案例研究法,为S公司营销策略的创新提出建议和启示。首先,本文回顾了4R营销理论、闭环供应链等有关理论知识,为本文主体部分的研究奠定理...Steel industry is an important foundation for national economy; it is the material guarantee for the development of the country, also represents the country’s economy level and comprehensive national power.

Research on the Impact of Paternalistic Leadership on Individual Accountability ——Moderated by Task Complexity
个体当责由于其对组织有效运行的重要性得到了理论界和实务界的广泛关注。已有的个体当责研究主要是在西方情境下的,且主要关注了个体当责及其影响结果,如个体当责对工作绩效、工作满意度、组织公民行为等的影响,而对个体当责的前置因素的探讨则相对较少。在已有的研究中,有学者提出观众可能是影响个体当责的关键因素。家长式领导植根于中华文化,对员工的行为和态度均产生重要影响。因此,探讨家长式领导作为对个体当责的前置因素研究具有重要意义。 本文首先采用文献研究法对个体当责研究的发展历程以及影响因素进行了梳理,然后引入家长式领导和工作复杂性分别作为个体当责的影响因素和调节因素,并建立理论假设和研究模型。之后,利用预...Individual accountability has attracted practitioners and scholars’ attention since its great impact on organizations. The existing researches about individual accountability are under western country and major of them are about the consequences, including job performance, job satisfaction and OCB and so on. However, the influencing factors of individual accountability have remained unclear. Previ...学位:管理学硕士院系专业:管理学院_企业管理学号:1762013115128
A Research on Performance Management Optimization in EDFA Career Partner System Strategic transition period
在经济全球化的当今世界,由于互联网以及与之相伴随的通信技术的高速发展,技术和产品方面的差异已经不再是一种关键性的竞争优势,获得竞争对手的技术及产品特征变得相对容易,通过新技术或新产品已经很难占得一段时期的竞争优势。真正能够提供核心竞争优势的关键资源,已逐步转变为由“人”所提供而形成的“人力资本”,只有人才能给企业带来可持续的竞争优势。而绩效管理体系,则是能够将人的才能和动力转化为一种企业战略优势的各种关键工具的组合。 在国内经济市场,由大型跨国企业引领的迅速变化的经营运作模式,对小微企业不断带来冲击与考验,不断变幻的政策波动及市场局势,使小微企业不能不艰难抉择、稳步求生。尤其笔者任职人事行政...Abstract In today's world of economic globalization, due to the rapid development of the Internet and associated with communication technology, product technology and the difference is no longer a key competitive advantage, become relatively easy access to the competition of technology and product characteristics of, by new technology or a new product has been very difficult to account for the co...学位:工商管理硕士院系专业:管理学院_工商管理硕士(工商管理硕士)学号:1792012115059

A preliminary study on mechanisms of fission yeast Dnt1 participating in accurate chromosome segregation and efficient G2/M transition
在裂殖酵母中,Dnt1主要定位在核仁里,在有丝分裂后期还定位在纺锤体上。本实验室之前的研究发现,Dnt1对于纺锤体检验点的沉默是必需的;另外Dnt1通过下调Wee1蛋白水平调控细胞G2/M转换以及胞质分裂。 本研究通过对染色体分离情况的精确观察,我们发现Dnt1与Monopolin蛋白(Pcs1/Mde4)、AuroraB激酶Ark1分别通过不同途径防止姊妹染色体的merotelicorientation,在染色体准确分离过程中起着重要作用。利用nda3-KM311cdc13-GFPark1-as3纺锤体检验点沉默筛选系统,我们进一步确认Dnt1与SAC的关键组分Bub3在不同的通路上调控检...In the fission yeast Schizosaccharomyces pombe, Dnt1 mainly localizes in the nucleolus, and it also appear on the spindle at anaphase. Our previous studies found that Dnt1 positively regulates G2/M transition and cytokinesis by down-regulating protein levels of Wee1 kinase, Dnt1 is also required for the spindle checkpoint silencing. In this study, by observing chromosome segregation defects duri...学位:理学硕士院系专业:生命科学学院_细胞生物学学号:2162013115252

Adhesive behavior of two-dimensional power-law graded materials
In this paper, we investigate the adhesive contact between a rigid cylinder of radius R and a graded elastic half-space with a Young's modulus varying with depth according to a power-law, E = E-0(y/c(0))(k) (0 < k < 1), while the Poisson's ratio v remains constant. The results show that, for a given value of ratio R/C-0, a critical value of k exists at which the pull-off force attains a maximum; for a fixed value of k, the larger the ratio R/c(0), the larger the pull-off force is. For Gibson materials (i.e., k = 1 and v = 0.5), closed-form analytical solutions can be obtained for the critical contact half-width at pull-off and pull-off force. We further discuss the perfect stick case with both externally normal and tangential loads
