A case study of the impact of integrated project governances on PPP project performance

Under the new normal state, the PPP project will play a more and more important role in the social and economic development of China. To improve the performance of PPP project management, it is necessary to implement integrated project governances. Firstly, according to the index system of two kinds of PPP projects governances (Contract Governance and Relationship Governance) and PPP project management performance determined by theoretical analysis, the DDX project is selected as the analysis object. After identifying the case, this paper explains the basic information and preliminary work of the case. Then, the three contents of contract governance, relationship governance and project performance are analyzed comprehensively. Case studies show that all of these two governance modes have positive effects on project management performance. However, due to the lack of information in the case, the validity of the conclusion also needs to be verified again.     

递阶双因素模型估计信用组合一致性风险

当信用组合内资产个数较少时，基于Gordy提出的粒度调节方法计算的组合风险量度VaR将严重被低估，从而高估一致性风险量度预期短缺ES。本文利用Taylor展开式改进粒度调节方法，提高估计ES的准确性；并且假设行业因素是宏观经济因素的线性函数，由此保证了组合不变性的条件，从而扩展单因素模型为递阶双因素模型，提高相关性估计准确性，解决了单因素模型高估经济资本的问题。模拟结果显示递阶双因素模型的优越性，特别是组合内资产规模较小时，改进的效果更明显。     

徘徊在圣母和夏娃之间——论《拉格泰姆时代》中的女性形象和两性关系模式

对E．L．多克托罗《拉格泰姆时代》的文学评价大多集中在小说的叙述策略与历史重构、新历史主义、后现代主义艺术技巧、文本的历史性及其变形意向和电影手法上,小说中的女性被仅仅当作了背景和陪衬。笔者在对文本细读的基础上,运用理安·艾斯勒的两性关系模式——统治关系模式和伙伴关系模式——及女性主义相关理论诠释和解读了小说中的女性形象和两性关系。     

组合仓单质押贷款质押率研究

物流金融是一项创新型的物流增值服务,仓单质押是其中一种重要的融资模式。本文采用copula函数对组合质押商品的价格变动进行描述,通过分析质押过程得出商品价格变动导致的银行潜在损失。沿用Morton信用风险结构型模型的方法,构造了借款企业违约概率函数,进而得出银行信用风险损失函数,最后建立银行仓单质押业务成本函数,通过求解非线性规划确定质押率这一关键指标。
