钢琴艺术指导教学中对交响因素的认识与演绎——以马勒《旅行者之歌》为例

自21世纪钢琴艺术指导进入中国后,虽然“名”得到了纠正,但在“实”上仍存在诸多问题,尤其是钢琴艺术指导教学中的现有教学内容并不能满足对于具有交响性的声乐作品进行完美演绎。通过对钢琴艺术指导视域下交响性与交响因素全新认识,提出对钢琴艺术指导者交响性思维的培养、音乐创作技法分析的重视、交响性音效的听觉训练,教授钢琴艺术指导专业学生从创作观念与技法中提炼交响因素、在演奏技法上放大交响因素特征、在人声配合下呈现交响性效果,最终实现对交响因素的完美演绎。

多视角的音乐文化传承 莫扎特钢琴协奏曲中“华彩乐段”的起源探究

文章从莫扎特的两部典型的钢琴协奏曲的“华彩乐段”同赫里斯齐安和埃曼纽尔的两部协奏曲进行比较分析，探索莫扎特钢琴协奏曲的起源问题，以便我们更好地理解莫扎特的钢琴协奏曲乃至18世纪的协奏曲的风格，从而让我们更好地多视角地传承音乐文化，使其得到更深远的发展。

Empirical Test of Determinants of Accepting Mobile Payment

From a global perspective, the develop ment of 3G services in China is quite different from other countries. The factors that influence users＇ adoption of mobile payment are worth ex ploring. This study employs the Technology Ac ceptance Model （TAM） to examine determinant factors affecting consumers＇ acceptance intentions of mobile payment. We adopt Hofstede＇s cultural dimensions as moderators to extend the TAM model for exploring the impact of uncertainty a voidance on mobile payment acceptance.

Traffic condition estimation with pre-selection space time model

A pre-selection space time model was proposed to estimate the traffic condition at poor-data-detector,especially non-detector locations.The space time model is better to integrate the spatial and temporal information comprehensibly.Firstly,the influencing factors of the "cause nodes" were studied,and then the pre-selection "cause nodes" procedure which utilizes the Pearson correlation coefficient to evaluate the relevancy of the traffic data was introduced.Finally,only the most relevant data were collected to compose the space time model.The experimental results with the actual data demonstrate that the model performs better than other three models.

Analysis of the mechanical property of mudstone/shale in paralic coal measures and its influence factors

The mechanical property of mudstone/shale in coal measures is a key factor of engineering mechanics that influences the development of shale gas. A rock mechanics test was performed in order to analyze the complete stress-strain mechanic characteristics and influence factors of mudstone/shale in paralic coal measures, from the Carboniferous-Permian periods in a coal field of Northern China. The relationship between the mechanical properties of mudstone/shale in coal measures, and its chemical component, water content are established, and their models are constructed. Research results show that mud- stone/shale has low mechanical strength, low elastic modulus and a high Poisson＇s ratio. The complete stress-strain curve has apparent elastoplastic deformation characteristics, and after reaching peak strength, it exhibits obvious strain softening characteristics. The uniaxial compressive strength of mudstone/shale and its elastic modulus increases exponentially with the increase of SiO2 content, and as the ignition loss increases, the uniaxial compressive strength and elastic modulus of mudstone/shale will decrease according to the law of power function. The compressive strength of mudstone/shale and its elastic modulus will decrease with the increase of water content in mudstone/shale.

Social Network Impacts on Stock Market： An Experimental View

In this paper, the authors present a method to construct a simulation experiment system which used to prove how social network affects the stock market. The authors construct a model considered of three main stock market effect factors： cognitive factors, social factors and economic factors. In the simulation system, free-scale social network is generated for information relations among investors in stock market. The authors simulate the organization information propaganda processes and generate stock related news. The generated news contains economy factors and sudden events. Stockholders cooperate with the related stockholders in their social network, and make stock exchange decision based on this news and their cognitive understanding of this news. Simulation results shows that the social network news propaganda effect stock prices. If social network in stock market have circles, the news affection will be amplified.

Relationship Between Outdoor and Indoor Ozone Pollution Concentration

This paper analyses the changing rule of indoor ozone concentration and its influencing factors.A formula of indoor-outdoor concentration ratio(I/O ratio) was deduced based on the indoor ozone mass-balance equation.The ozone I/O ratio in different kinds of buildings was studied.Results show that I/O ratio is much related to air-exchange rate,which is well compatible with the theoretical calculation results.

Analysis on Influence Factors and Reduction Ways of Automotive Safety Cost

The paper introduces automotive safety cost formula, which defines the concept of private costs, technology costs and social costs and analyzes the impact of economic externalities in individual purchase decisions on urban traffic safety in the private costs and discusses the concept of hard and soft technology and its function to improve vehicle safety. Take people, vehicles and the environment as the main line and points out the promoting role of the relevant state departments, policy, research institutions and transportation infrastructure in the social cost for the entire transportation system security. Finally, about the security of car crash in low speed on urban roads, the paper gives some recommendations as for private costs, technology costs and social costs factor.

Factors Influencing the Voluntary Disclosure of Vietnamese Listed Companies

This paper aims to investigate the factors affecting the extent of voluntary disclosure by examining the annual reports of 205 industrial and manufacturing companies listing on Ho Chi Minh Stock Exchange （HSX） and Hanoi Stock Exchange （HNX） for the year of 2012. Those factors include company size, profitability, leverage, state ownership, managerial ownership, and foreign ownership, board independence, role duality, and type of external auditors. Evidence from this study suggests two main findings： （1） Companies with high foreign ownership have a high level of voluntary disclosure; （2） The company size is an important factor related to the increased level of voluntary disclosure in annual reports of Vietnamese listed companies. However, no significant associations are found between profitability, leverage, state ownership, managerial ownership, board independence, role duality, and type of external auditors as hypothesized in this study.
