International Journal of Online Engineering (iJOE) , 2013, DOI: 10.3991/ijoe.v9is2.2603
Abstract: An assessment framework is made to evaluate the performance factors of marine industries from the perspective of eco-economics by means of the AHP and the Delphi methods. Results are as follows: Performance assessment index of marine industries is decided by ecological performance, economic performance and social performance with ecological index taking priority over economic index; the efficiency of economy output and value-creating are preferred in the pursuit of low energy-consuming and less polluting marine industries; and in the near future, marine industries will make the greatest contribution to employment.
How Does Growth Follow Differential Convergence Patterns? A Study of the Chinese Regions and Sectors  [PDF]
Yanqing Jiang
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.48090
Abstract: This paper focuses on examining differential convergence patterns in productivity growth in China. Our empirical analysis shows that the Chinese provinces exhibit absolute divergence and then absolute convergence respectively during 1990-2000 and 2000-2010. In addition, absolute convergence is present during 1985-1995 and 2000-2010 in the primary sector and during 1995-2010 in the secondary sector. Our regressions also show that either for the overall regional economy, or for any individual sector, growth in labor productivity exhibits strong convergence. Besides the convergence trends, we also find that the secondary and tertiary sectors have grown significantly faster than the primary sector.
Spatial Distribution of Foreign Direct Investment and Productivity Growth in Less Developed Regions of China  [PDF]
Yanqing Jiang
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.411070
Abstract: This study examines how the spatial distribution of foreign direct investment (FDI) affects productivity growth in less developed regions of China. A systematic theoretical framework is set up concerning the potential effects of FDI capital via different channels. Following the theoretical framework, this study presents empirical evidence showing that FDI spillovers from the developed regions play a crucial role in enhancing productivity growth in the less developed regions. Empirical results also show that local FDI spillovers in less developed regions promote local productivity growth. In addition, FDI spillovers from less developed regions are not shown to have a significant effect on productivity growth in other less developed regions.
Second Language Vocabulary Learning in Multimedia Context

Sun Yanqing,Dong Qi,

心理科学进展 , 2003,
Abstract: Learning in context is an important approach of second language vocabulary learning. Compared with text-based context, multimedia context is more authentic, vivid and attractive because of the integration of information in audio, video, graphic, animation, as well as verbal format. The present paper discussed the concept of contextualized learning, the characteristics in learning L2 vocabulary in multimedia context and the related factors. The problems for future studies were also proposed.
Preparation and Characterization of Strong Polar Macro Porous Resin
Xin Qi,Yanqing Li,Denghu Chang,Jianhui Zhang
International Journal of Chemistry , 2011, DOI: 10.5539/ijc.v3n2p210
Abstract: The macro porous adsorption resin produced in this experiment mainly uses dipole dichloride etc. as the material, a certain proportion of mixed solution composed of pyridine and 1, 4-dioxane as the composite oxidant. Then adding a certain proportion of mixed solution composed of cyclopean and paraffin in the homogeneous solution of cellulose as the photogenic agent. As a result, these materials will polymerize, and generate the resin. Among these materials, the cellulose is polymeric monomer, dipole dichloride is cross linker, and they crosslink and polymerize each other, forming the porous skeletal structure of the macro porous adsorption resin, which is a kind of cross linked polymer consisting of ion exchange group. For the synthetic macro porous resin, using Fourier infrared spectrometer for pressed characterization, and scanning electron microscope (SEM) for resin pore-forming characterization, the result shows that the new macro porous resin has been synthesized. This paper taking ruin as adsorb ate explores the adsorption property of the synthetic macro porous resin to glycoside material, including property of equilibrium adsorption, static adsorption and adsorption. Meanwhile the influence of different solvents on the resin adsorption property is testified. After a general comparison, we have found that the resin has the strongest adsorption property in ethanol solvent, while for adsorption, the best effect is reached when using water as the elegant. What's more, the adsorption data shows that the adsorption of ruin on the very resin conforms to the Freundlich isothermal adsorption equation.
An Empirical Analysis of the Effects of Agricultural FDI on the International Competitiveness of Agricultural Products in China  [PDF]
Yanqing Jiang, Gaoyan Shi
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.511096
Abstract: Under the background of the reform and opening-up, as well as continuous economic growth and development, China’s attractiveness for foreign direct investment (FDI hereinafter) has shown an increasing trend year after year. However, FDI is distributed unevenly in the three broad industrial sectors. Through our investigation to the utilization of agricultural FDI, we find that the size and scale of FDI utilized in agriculture lagged far behind with manufacturing and service sectors and distributed unevenly across geographical regions. The “agriculture, rural areas and farmers” issue has always been one of the most important and difficult issues in the process of China’s economic reform. The main focus of this paper is on what impacts FDI has on the agricultural sector of the macroeconomy and how we should fully utilize FDI in order to alleviate trade deficit in agricultural products and enhance the international competitiveness of agricultural goods in China.
Th17: A New Participant in Gut Dysfunction in Mice Infected with Trichinella spiralis
Yu Fu,Wenfeng Wang,Jingjing Tong,Qi Pan,Yanqing Long,Wei Qian,Xiaohua Hou
Mediators of Inflammation , 2009, DOI: 10.1155/2009/517052
Abstract: Trichinella spiralis infection in rodents is a well-known model of intestinal inflammation associated with hypermotility. Our aim was to elucidate if Th17 cells were involved in the development of gastrointestinal hypermotility in this experimental model. Intestinal inflammation was observed by hematoxylin-eosin (HE) staining. Jejunal smooth muscle contractility was investigated in response to acetylcholine (Ach). The effects of IL-17 on jejunum smooth muscle contractility were explored. Flow cytometry was used to analyze the proportion of Th17 cells in jejunum. The levels of IL-17, IL-23, and TGF-1 in jejunum were measured by Western blot. Our results showed that the inflammation in jejunum was severe at 2 weeks postinfection (PI), which was not discernible at 8 weeks PI. Jejunal smooth muscle contractility was increased at 2 weeks PI and kept higher at 12 weeks PI. The proportion of Th17 cells and the expression of IL-17 were upregulated in jejunum at 2 weeks PI and normalized at 8 weeks PI. When jejunual smooth muscle strips were cultured with IL-17, contractions elicited by Ach were enhanced in a concentration-dependent manner. Our data suggest that Th17 cells are increased during acute infection with Trichinella spiralis and IL-17 may contribute to jejunal muscle contractility in mice.
A Cognitive Linguistic Approach to Classroom English Vocabulary Instruction for EFL Learners in Mainland China
Yanqing Chen
English Language Teaching , 2009, DOI: 10.5539/elt.v2n1p95
Abstract: Vocabulary learning and teaching has been one of the main issues in ESL/EFL learning and teaching research. EFL teachers in China, in particular, are grappling with the effective vocabulary teaching methods. This paper is doing part of this job in a different way. It discusses three principles based on Cognitive Linguistics (CL), namely the study of categorization, prototype, and metaphor, and implications of these principles in formal vocabulary instruction in a Chinese context of English learning in South-western mainland China.
A Semidiscrete Galerkin Scheme for Backward Stochastic Parabolic Differential Equations
Yanqing Wang
Mathematics , 2015,
Abstract: In this paper, we present a numerical scheme to solve the initial-boundary value problem for backward stochastic partial differential equations of parabolic type. Based on the Galerkin method, we approximate the original equation by a family of backward stochastic differential equations (BSDEs, for short), and then solve these BSDEs by the time discretization. Combining the truncation with respect to the spatial variable and the backward Euler method on time variable, we obtain the global $L^2$ error estimate.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102783
In modern educational fields, the quality education is put more weight, which aims to reduce the heavy homework burden of students and enhance the quality of students and the mass of education. Some theories, such as the constructivism learning theory and cognition education, are put forward and used fully. In the reform, the Dulangkou Middle School has created a unique teaching mode. The impact of the mode is very extensive, and it upsurges the thinking for subjectivity education and subjectivity learning strategies. The theses, at first, state some concepts, such as the subjectivity education and the subjectivity learning strategy, and survey and analyze the problems in the traditional English classroom teaching, and then analyze the teaching mode of Dulangkou. Through contrasting and analyzing the problems in the traditional English classroom teaching and creative methods of Dulangkou, some knowledge about the meaning of developing the subjectivity of students is put forward to further explore how to develop the subjectivity of students.
