浅谈宏观经济学教学内容改革方案

现如今的宏观经济学教学内容普遍存在过度西化和偏重理论的不足,使培养应用型人才的实现加大了难度.中国改革开放的实践为宏观经济学教学内容改革提供了诸多方案,而教学手段、教学指导文件、科研、教学案例、教学体系等方面则是教学内容改革所必须包括的.     

以过程为导向的《标识设计课程》教学新模式探析

介绍了基于过程化教学的标识设计教学新模式：根据标识设计内容的难易程度，组织循序渐进的教学内容；根据标识设计中技术到思想的难度，对相应的教学知识点进行对接，设计阶梯式的训练课题；根据标识设计内容构成的实践性特点，强化实践教学环节，针对每一个课题设计不同的实践方法，实现课堂与实践之间跨度的融合与穿插。     

多气源掺混作为城市燃气过渡气源在实际中的应用

为了解决青岛市煤气供需不平衡的矛盾,为引进天然气作好前期准备,我公司将多种气源(焦炉煤气、焦炉烟道气、空气、全水煤气、半水煤气、液化石油气、石化厂净化干气)均匀掺混,掺混后的煤气热值控制在15 675～17000 kJ/m3(适合青岛市燃具),含氧量不大于4.0%.通过实际应用,多气源掺混供气,满足了供气需要,可以作为过渡气源满足城市燃气转换成天然气的需要.     

Two new proofs of Afriat’s theorem

Summary. We provide two new, simple proofs of Afriats celebrated theorem stating that a finite set of price-quantity observations is consistent with utility maximization if, and only if, the observations satisfy a variation of the Strong Axiom of Revealed Preference known as the Generalized Axiom of Revealed PreferenceReceived: 12 June 2003, Revised: 9 October 2003, JEL Classification Numbers: D11, C60.Correspondence to: A.

A Note on the Joint Distribution of α, β-Percentiles and Its Application to the Option Pricing

In this paper, using Laplace transform, we will calculate the joint density of twopercentiles of stock prices in the Black–Sholes model and make the price of exchange options of such twopercentiles.     

Estimating the term structures of corporate debt

This paper investigates the corporate bond market by estimating monthly interest rate term structures for investment grade credit classes using both S&P's and Moody's ratings. Term structures are modeled by a piecewise constant forward rate curve and estimated on noncallable coupon paying bonds issued by industrial firms. The iterative estimation algorithm minimizes the sum of squared errors between market prices and model prices while identifying and removing outliers from the sample. Although the forward rate model is successful at pricing corporate debt, additional factors are found to be significant at explaining the residual price error that remains after the forward rate model is fit to market prices. Six necessary no-arbitrage conditions are derived for the term structures of risky and risk-free debt. Occasionally, some of these no-arbitrage conditions are violated and a few violations are asymptotically statistically significant. Finally, trading strategies that capture mispricing in the corporate debt market and violations of no-arbitrage bounds are discussed.This paper was adapted from my dissertation, completed at Cornell University. An earlier version of this paper was titled The Term Structures of Corporate Debt. Thanks to participants at the Cornell University finance workshop, Warren Bailey, Peter Carr, Antoine Giannetti, and especially Robert Jarrow for their helpful comments.     

The Effectiveness of Brand- and Customer-Centric Content Strategies at Generating Shares, ‘Likes’, and Comments

Brands are constantly competing for user attention on Facebook and are trying to encourage fans to share, click ‘like’, and comment their posts. Yet, it remains unclear what content strategies are successful at encouraging those behaviors. Noting that the effectiveness of brand content strategies still remains an uncharted research area, this study adopts a discovery-oriented approach and employs workshops, quantitative content analysis, and episodic interviews, to link desired user responses (namely clicks share, ‘like’, and comment) to brand content strategies. This study reveals that customer-centric content strategies are the most effective at encouraging user responses. Managers can use provided recommendations to engage their customers by adopting content strategies that result in desired behavioral reactions.
