On Farmer’s Willingness to Small Forest Tenure Mortgage Loans —A Case Study on Yibin of Sichuan
Xin Cai,Weizhong Zeng
International Journal of Business and Management , 2011, DOI: 10.5539/ijbm.v6n3p272
Abstract: Based on the survey data of 364 peasant households in Yibin, Sichuan, this paper analyzes the farmer’s willingness to small forest tenure mortgage loans. The result indicates a high willingness up to 74.2%, i.e. the farmers are willing to invest forest tenure mortgage loans into forestry and agricultural production. The influential factors on farmer’s willingness to small forest tenure mortgage loans include age, education, forest area, the main source of family income, perception on the policies of forest tenure mortgage loans, social services of forestry, financial institutions, etc. We propose the policy advocacy of forest tenure mortgage loans be enhanced, mortgage loans of different period be designed for different purposes, and discount policy on small mortgage loans be issued.
Impact of household endowments on response capacity of farming households to natural disasters
Haixia Zhang,Tianhui Zhuang,Weizhong Zeng
International Journal of Disaster Risk Science , 2012, DOI: 10.1007/s13753-012-0022-2
Abstract: This article investigates the impact of household endowments on household’s ability to cope with natural disaster risks and the determining factors of disaster coping capacity. We present results of a research based on household survey. The data were analyzed with an ordered Probit model regression. The project surveyed 923 rural households in 2009 and 2010 in 39 national-level poverty-stricken counties of Sichuan, Yunnan, and Guizhou Provinces and Chongqing Municipality. This research determined that the economic strength of households is the most important factor affecting their disaster coping capacity. The ability of farming households to cope with disasters is also significantly impacted by family members’ experiences and their economic context at the village level. Ethnic minority areas in southwestern China are the poorest in the country and are often the main disaster-affected areas. Since household endowments significantly affect the ability of farming households to cope with disasters, integration of disaster risk management and poverty reduction is a viable way of enhancing coping capacity of farming households to natural disasters.
The Willingness to Pay for the Ecological Compensation of Min River Basin -- Based on the Survey of Chengdu 282 Households

Environment and Pollution , 2012, DOI: 10.5539/ep.v1n2p14
Abstract: The mechanism of ecological compensation is considered as an effective way to solve the problems of the upstream and downstream river basins. This paper uses the Contingent Valuation Method (CVM) to investigate people’s awareness of Min river basin's ecological compensation, and analyze the willingness to pay for the environmental improvement. Studies have shown that residents of Chengdu have a certain degree of eco-environmental awareness and willingness to pay, but the cognitive level of ecological protection isn't enough, and show a "government dependency" feature. 67.73 % of the surveyed residents were willing to pay for the restoration of the ecological environment of Min river, and the average maximum willingness to pay was 63.47 Yuan / (person·year).

Weikang Zhang,Weizhong Zeng,Xinhong Fu,Jimin Pan
Journal of Management and Sustainability , 2011, DOI: 10.5539/jms.v1n1p124
Abstract: The tragedy of the commons of river describes the plight of continuous exhaustion of the river resources. Its essence is because resources are excessive used. It takes the river pollution as an example in this paper, under the traditional hypothesis of classical economics, to analyze the reasons for the formation of tragedy of the commons of the rivers briefly, which is caused by repeated pollution actions among the inhabitants and the institution is important to solve it resultantly, in the view of game theory. Then, on the basis of New Institutional Economics (NIE), the discussion separately from microscopic, intermediate and macroscopic perspectives explores and answers what the institutions should be for tragedy of the commons of the rivers. Next is the case analysis of Jinhua River. It comes to the conclusions: the government could exploit planning mechanism and price mechanism generally, providing proper river property rights arrangement, to reduce various transaction costs and establish the river compensation system.
Developing Human Capital Capabilities of Top Management Team for CoPS Innovation  [PDF]
Yuhui GE, Weizhong YANG
Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.23027
Abstract: Top management team (TMT) play key roles in many industries and firms. Human resources is continuously developed and considered to be a competitive advantage. Traditional research on TMT has, however, paid scant attention to the human capital capabilities of TMT needed for firms. Furthermore, traditional work on TMT of firms pays limited attention to its specific traits in complex products and systems (CoPS) innovation. In the present paper, we explore the development of human capabilities of TMT observed in CoPS innovation firms. We developed a model for analysis the human capital capabilities of TMT for CoPS Innovation, and suggested that a dynamic interplay between the development of human capital capabilities of TMT and the changing CoPS innovation environment, and human capital capabilities of TMT for CoPS innovation could be developed through team learning. And we formulated an empirical research framework for the analysis of factors affecting the human capital capabilities of TMT for CoPS innovation. Four key factors were identified and extracted by using factor analysis, and these resulting factors were related to the performance of CoPS innovation by using a multiple regression analysis method. The proposed framework identified four blocks of human capital capabilities of TMT for CoPS innovation, namely technology innovation management, risk management, organization management and relationship network management. The paper argues that TMT for CoPS innovation firms are only able to effectively harness and develop their human capital capabilities by team learning and integrating these four building blocks within the team.

Abstract: Influenza A virus NS1 protein is an important regulatory factor with multiple functions and contributes greatly to viral pathogenesis. In the present study, transcription-activating potential of NS1 from different influenza A virus subtypes was examined in yeast two-hybrid system. The bait vectors containing different NS1 genes, along with an empty prey vector, were transformed into yeast AH109(for growth assay on QDO plate and α-galactosidase assay), and Y187(for β-galactosidase assay). AH109 transformants with NS1 gene from H1N1, H5N1, and H9N2 viruses grew vigorously on the QDO plate and secreted high level of α-galactosidase. Also, Y187 bearing the above NS1 genes exhibited enhanced β-galactosidase activity. Nevertheless, H3N2-NS1-transformed AH109 and Y187 yeasts did not grow on QDO plate and secrete β-galactosidase, respectively. These findings denote the remarkable variation in NS1 proteins from different influenza A virus subtypes on the transcription-stimulating capability in yeast.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0078003
Abstract: Purpose To examine the prevalence of refractive errors in children aged 3–6 years in China. Methods Children were recruited for a trial of a home-based amblyopia screening kit in Guangzhou preschools, during which cycloplegic refractions were measured in both eyes of 2480 children. Cycloplegic refraction (from 3 to 4 drops of 1% cyclopentolate to ensure abolition of the light reflex) was measured by both autorefraction and retinoscopy. Refractive errors were defined as followed: myopia (at least ?0.50 D in the worse eye), hyperopia (at least +2.00 D in the worse eye) and astigmatism (at least 1.50 D in the worse eye). Different definitions, as specified in the text, were also used to facilitate comparison with other studies. Results The mean spherical equivalent refractive error was at least +1.22 D for all ages and both genders. The prevalence of myopia for any definition at any age was at most 2.5%, and lower in most cases. In contrast, the prevalence of hyperopia was generally over 20%, and declined slightly with age. The prevalence of astigmatism was between 6% and 11%. There was very little change in refractive error with age over this age range. Conclusions Previous reports of less hyperopic mean spherical equivalent refractive error, and more myopia and less hyperopia in children of this age may be due to problems with achieving adequate cycloplegia in children with dark irises. Using up to 4 drops of 1% cyclopentolate may be necessary to accurately measure refractive error in paediatric studies of such children. Our results suggest that children from all ethnic groups may follow a similar pattern of early refractive development, with little myopia and a hyperopic mean spherical equivalent over +1.00 D up to the age of 5–6 yearsin most conditions.

Science China Life Sciences , 2012, DOI: 10.1007/s11427-012-4335-6
Abstract: Non-structural protein 1 (NS1) of the influenza virus plays a crucial role in modulating the host immune response and facilitating virus replication. The formation of a homodimer or an oligomer is necessary for NS1 to exert its function efficiently. In the present study, the NS1 protein from the A/Shantou/602/06(H3N2) virus (herein abbreviated as NS32) was found to interact with NS1 from A/Shantou/169/06(H1N1), A/Chicken/Guangdong/1/05(H5N1) and A/Quail/Hong Kong/G1/97(H9N2) (abbreviated as NS11, NS51 and NS92, respectively) viruses, although NS32 shares 17.4%–20.9% sequence diversity with NS11, NS51 and NS92. This indicates that the heterologous interactions between NS1 proteins from different influenza A virus subtypes/ strains may be a common event during co-infection.
