Yong Yang
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.83042
Abstract: From the intermediate demand perspective of the industry, agriculture and services, this paper analyzes the problems on the development of producer services in China and gives some related causes. To accelerate the development of producer services in an even better fashion, we think the following measures should be taken: developing the high-end manufacturing and promoting the interaction between manufacturing and producer services; attaching equal importance to imported technology and independent innovation; improving the promotion and training for agricultural technology and optimizing agriculture production structure; developing the modern service industry; enhancing the supplying quality of producer services.
Volume of Derivative Trading, Enterprise Value, and the Return on Assets  [PDF]

Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.48055

We study how the volume of derivatives trading is associated with the return on assets (ROA), as well as the enterprise value proxied by abnormal return (AR), before and after the US Financial Crisis. Results suggest that before the crisis, the volume of over-the-counter trading, which tends to be less strictly regulated and thus can be more flexibly applied, is positively associated with AR and ROA, while exchange trading is not. After the financial crisis, exchange trading, which is more heavily regulated and thus has lower credit risks, is positively associated with AR and ROA. This implies that the kinds of derivatives products having a positive or negative effect on the enterprise value of financial institutions may vary according to each period of the economy. Therefore, in full consideration of the above, it is recommended that more appropriate alternatives to the regulations and inspections should be provided for derivatives products and trading methods of financial institutions.

Knowledge Sharing, Organizational Learning and Service Innovation in Tourism  [PDF]
Yong Rao, Manni Yang, Yuexuan Yang
Journal of Service Science and Management (JSSM) , 2018, DOI: 10.4236/jssm.2018.115035
Abstract: Knowledge sharing is a key factor that influences the organizational learning, service innovation and competitive advantage of tourism enterprises. Despite the fruitful research achievements in knowledge sharing since the 1990s, there is no appropriate framework to effectively summarize existing research literature due to the complexity of the tourism knowledge system. This article, based on the research path of knowledge sharing, summarizes the knowledge sharing research literature in tourism industry according to the framework of “organizational learning - service innovation - competitive advantage”, and analyzes the research results of the relationship between knowledge sharing and organizational learning, knowledge sharing and service innovation as well as knowledge sharing and competitive advantage. On this basis, this article further analyzes the role and function of knowledge sharing in the closed loop of “organizational learning - service innovation - competitive advantage”, with the aim of providing reference for knowledge sharing research in tourism.
Image segmentation based on fuzzy clustering with neighborhood information
Yong Yang
Optica Applicata , 2009,
Abstract: In this paper, an improved fuzzy c-means (IFCM) clustering algorithm for image segmentation is presented. The originality of this algorithm is based on the fact that the conventional FCM-based algorithm considers no spatial context information, which makes it sensitive to noise. The new algorithm is formulated by incorporating the spatial neighborhood information into the original FCM algorithm by a priori probability and initialized by a histogram based FCM algorithm. The probability in the algorithm that indicates the spatial influence of the neighboring pixels on the centre pixel plays a key role in this algorithm and can be automatically decided in the implementation of the algorithm by the fuzzy membership. To quantitatively evaluate and prove the performance of the proposed method, series of experiments and comparisons with many derivates of FCM algorithms are given in the paper. Experimental results show that the proposed method is effective and robust to noise.
Multiresolution Image Fusion Based on Wavelet Transform By Using a Novel Technique for Selection Coefficients
Yong Yang
Journal of Multimedia , 2011, DOI: 10.4304/jmm.6.1.91-98
Abstract: Today, image fusion as one kind of information integrated technology has played an important role in many fields. This paper presents a novel wavelet based technique for image fusion, which is developed by taking into account the physical meaning of the wavelet coefficients. The images to be fused are firstly decomposed into high frequency and low frequency bands by wavelet transform. Then, by considering the physical meaning of the coefficients, a new selection strategy that treats the coefficients in different ways is proposed. This strategy selects the coefficients of high frequency bands with a variance based scheme, while selects the coefficients of low frequency band with an edge based scheme. Finally, the fused image is constructed by an inverse wavelet transform performing on the combined coefficients from all frequency bands. The proposed method is validated and compared with some existing fusion methods. Experimental results can clearly indicate the superiority of the proposed method through visual inspection and objective fusion performance measurements.
Blocks of small defect

Mathematics , 2012,
Abstract: Let $G$ be a finite solvable group, let $p$ be a prime such that $p \geq 5$ and $O_p(G)=1$, and we denote $|G|_p=p^n$, then $G$ contains a block of defect less than or equal to $\lfloor \frac {3n} 5 \rfloor$. Let $G$ be a finite solvable group and let $p^a$ be the largest power of $p$ dividing $\chi(1)$ for an irreducible character $\chi$ of $G$, we show that $|G:\bF(G)|_p \leq p^{3a}$ for $p \geq 5$.

Mathematics , 2015,
Abstract: Let $p$ be a prime such that $p \geq 5$. Let $G$ be a finite $p$-solvable group and let $p^a$ be the largest power of $p$ dividing $\chi(1)$ for an irreducible character $\chi$ of $G$, we show that $|G:F(G)|_p \leq p^{5.5a}$. Let $G$ be a finite $p$-solvable group with trivial maximal normal solvable subgroup and we denote $|G|_p=p^n$, then $G$ contains a block of defect less than or equal to $\lfloor \frac {2n} {3} \rfloor$.

Mathematics , 2014,
Abstract: Let $G$ be a permutation group of degree $n$ and let $s(G)$ denote the number of set-orbits of $G$. We determine $\inf(\frac {\log_2 s(G)} n)$ over all groups $G$ that satisfy certain restrictions on composition factors (i.e. $Alt(k), k > 4$ cannot be obtained as a quotient of a subgroup of $G$).

A Study of Changes in Risk Appetite in the Stock Market and the Housing Market before and after the Global Financial Crisis in 2008 Using the vKOSPI  [PDF]
Jin Yong Yang, Sang-Heon Lee
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.411077
Abstract: This study analyzes the empirical relationship between the vKOSPI, which is the Korean VIX (implied volatility index), and the housing market (rent1-to-house price ratio) based on monthly data from January 2003 to November 2012. The data were divided into two parts before and after the global financial crisis in 2008 and were analyzed by using the Vector Autoregressive (VAR) Model. The research results show that the influence of vKOSPI on the housing market changes from symmetric to asymmetric since the global financial crisis in 2008. Before the global crisis in 2008, the influence of the vKOSPI on the house price index and rent index is almost the same, so the influence on the rent-to-house price ratio is not statistically significant. However, since the global crisis in 2008, the influence of the vKOSPI on the two prices has changed asymmetrically and the influence on the rent-to-house price ratio was statistically significant. Second, the influence of the vKOSPI fluctuation on house sale prices and rent is shown differently according to the rise/fall of the vKOSPI. In the event of the vKOSPI rising, house prices would fall greatly. On the other hand, in the event of the vKOSPI falling, the rise in housing prices is relatively small. This means that while the boosted sentiment of investors in the stock market is not transferred to the housing sales market, the aggravated sentiment of investors affects the housing sales market easily. In conclusion, the uncertainty has been represented in the vKOSPI and the preference for risky assets has an asymmetrical influence on the market dependent upon the kind of market. We suspect that this is caused by complex factors including shrinking expectations for future house prices.
