资源科学 , 2011,
Abstract: 鄂尔多斯遗鸥自然保护区属于典型的半干旱区高原内陆湖泊湿地,地下水是其重要水源之一。本文以遗鸥湿地所在的泊江海子流域为研究对象,系统分析了地层岩性、含水系统及富水性、地下水流场特征、地下水水化学特征等基础水文地质条件,并计算了地下水系统的水均衡。结果表明:泊江海子流域主要有松散岩类孔隙含水层和碎屑岩类孔隙裂隙含水层,松散岩类孔隙地下水严格受闭流盆地地形条件控制;碎屑岩类孔隙裂隙地下水主要受区域地形及水文系统控制;大气降水补给和侧向径流补给是泊江海子流域地下水的主要补给源,两者约占总补给量的85%,而潜水蒸发和人工开采是地下水的主要排泄方式,约占整个系统排泄量的89%,1996年-2005年,泊江海子流域地下水总的年均补给量为6358.9×104m3/a,总排泄量为7418.2×104m3/a,地下水均衡差为-1059.3×104m3/a;桃-阿海子接受的地下水补给量约为142.5×104m3/a,占桃-阿海子湖泊总补给量的22%,是桃-阿海子湖泊的一个重要的补给来源。
Regulation of Electroacupuncture on Gastric Myoelectrial Activities: Monitered by Electrogastrograms  [PDF]
Peng Cheng
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B018

It is reported that acupuncture on some acupoints can enhance the regularity of gastric myoelectrical activities, which can be observed from the electrogastrograms (EEGs). In this paper, the electroacupuncture (EA) treatments were performed on subjects with slight gastric disorders and the EEGs were monitored in the meanwhile. The EEGs features of baseline, during and after EA treatments were analyzed. The results show that the EA treatments do enhance the regularity of EEGs. And a highly possible pattern for EA to attain the enhancement is to regulate the pacemaker quantity and propagation of slow waves rather than regulating the amplitude of slow waves.

Volatility Forecasting and Volatility Risk Premium  [PDF]
Jingfei Cheng
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.31014

Volatility is an important variable in the financial market. We propose a model-free implied volatility method to measure the volatility and test the volatility risk premium. The model-free implied volatility does not depend on the option pricing model, and extracts information from all the option contracts. We provide empirical evidence from the S & P 500 index option that model-free implied volatility is more accurate to forecast the future volatility and the volatility risk premium does not exist.

Small and Medium Sized Entities Management’s Perspective on Principles-Based Accounting Standards on Lease Accounting  [PDF]
Jierong Cheng
Technology and Investment (TI) , 2015, DOI: 10.4236/ti.2015.61007
Abstract: Lease accounting is viewed as one of the top priorities for the International Financial Reporting Standards (IFRS) convergence. Small and medium sized entities are an important part of the economy, and this research investigates the management’s perspective on the adoption of principles-based IFRS about lease accounting. This researcher interviewed four managers from three different small and medium sized entities, and found the management to be more concerned about their long-term business success than the change of accounting standards. Only when the entities have a loan with the bank, then the management focuses on the lease classification. The interview also suggests that the managers and business owners in the small and medium sized entities have limited knowledge and skills in accounting reporting standards. These firms outsource their accounting needs to local accountants rather than having their own in-house departments. The other aspect of focus for management of these firms is tax consequence of IFRS adoption. The research suggests other regulatory agencies, i.e., Internal Revenue Service, should also be involved in enhancing financial statement transparency and usefulness after the adoption of accounting standards.

Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.815168
Abstract: The scientific career planning of undergraduates is an important measure to promote the employment of Chinese college students and alleviate the shortage of enterprises. It is also the key measure of the “supply side” reform of Chinese higher education. This paper analyzes the feasibility and mechanism of career planning for Chinese college students based on online recruitment information. Taking the human resources management major as an example, the content analysis method based on online recruitment information is used to study Chinese college students’ career development path, job quality requirements and career planning stage Determine, and use dynamic network recruitment information using rolling planning method to carry out college career planning.
The Interdependence between the Demand of Fashion Industry and the Function of Fashion Education  [PDF]
Shiyuan Cheng
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.84073
Abstract: When the cultural industry is booming, fashion industry and fashion education emerge as the times require, and they are also derived from each other. Through the research, it is found that their relationship is specific, and the fashion education extends from the traditional only to the education of the industry, the education of the market and the education of the consumers. The form of fashion education is still education, but the essence has evolved into the pursuit of fashion innovation and the indoctrination of fashion culture, which is required by the development of fashion industry. This pursuit and instillation is through the production, management, marketing, brand, design and propaganda of the fashion industry. The external performance of fashion education is to cultivate all kinds of professional talents in fashion industry, but it is rooted in the innovation and creative breakthrough of fashion industry and products, thus promoting the continuous development of fashion industry through the role of human resources in fashion industry, and finally reaching the goal of leading the fashion industry with the power of knowledge. Fashion industry is developing. Fashion education is also developing, and is more and more popular in front of fashion industry, leading the development of fashion industry.

The Impact of Economic Policy Uncertainty on the Efficiency of Corporate Working Capital Management—The Evidence from China  [PDF]
Xi Cheng
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.103054
Abstract: As China’s economic development has entered a new era, economic policy regulation has become more and more frequent. While the government transform and restructure the economic development pattern through policy regulation, the uncertainty brought by the policy also has a negative effect on the investment and operation of the private sector. However, working capital management, as an important part of enterprise operation, has received little attention. From the perspective of economic policy uncertainty, this paper uses a sample of the listed non-financial enterprises of Shanghai and Shenzhen stock markets from 2000 to 2010 to study the impact of uncertainty on the efficiency of enterprise working capital management. We found that uncertainty has a negative impact on the efficiency of working capital management.
An adaptive significance threshold criterion for massive multiple hypotheses testing
Cheng Cheng
Mathematics , 2006, DOI: 10.1214/074921706000000392
Abstract: This research deals with massive multiple hypothesis testing. First regarding multiple tests as an estimation problem under a proper population model, an error measurement called Erroneous Rejection Ratio (ERR) is introduced and related to the False Discovery Rate (FDR). ERR is an error measurement similar in spirit to FDR, and it greatly simplifies the analytical study of error properties of multiple test procedures. Next an improved estimator of the proportion of true null hypotheses and a data adaptive significance threshold criterion are developed. Some asymptotic error properties of the significant threshold criterion is established in terms of ERR under distributional assumptions widely satisfied in recent applications. A simulation study provides clear evidence that the proposed estimator of the proportion of true null hypotheses outperforms the existing estimators of this important parameter in massive multiple tests. Both analytical and simulation studies indicate that the proposed significance threshold criterion can provide a reasonable balance between the amounts of false positive and false negative errors, thereby complementing and extending the various FDR control procedures.
