A study of fairness judgments in China, Switzerland and Canada
Yue Gao
Judgment and Decision Making , 2009,
Abstract: This study compares judgments of the fairness of economic actions among survey populations in Switzerland, and both student and non-student groups in the People's Republic of China, with the earlier Kahneman, Knetsch and Thaler (1986a) surveys of Canadians. The findings suggest that fairness concerns matter among all of these groups, and the general patterns of what was and was not considered to be fair were similar. However, there were also some significant differences with the influence of fairness being weaker in the two Chinese samples than in the groups from the Western countries, with the influence being weakest in the Chinese student population for the wage related topics. On the whole, almost no significant gender differences were found in any of the new surveys.
Board Gender Diversity, Earnings Quality and Stock Price Informativeness  [PDF]

American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.82018
Abstract: Further recognition of women’s social value and the gradual improvement of women’s economic status have made the proportion of female independent directors on board rise year by year, which has received high attention from academia. Using data of A-share listed companies in Shanghai and Shenzhen stock markets form 2000-2014 in China, this paper investigates the relation among gender diversity, earnings quality and stock price informativeness. As a result, the larger the proportion of female independent directors is, the more firm-specific information the stock price contains. In the meantime, earnings quality of listed companies significantly impact on stock price informativeness, which means that stock prices of companies with higher earnings quality contain more firm-specific information while having other factors controlled. Further studies show that the relation between board gender diversity and stock price informativeness is not simply direct; board gender diversity could raise the stock price informativeness through enhancing earnings quality.
Reproducing Kernel Space Method for the Solution of Linear Fredholm Integro-Differential Equations and Analysis of Stability
Xueqin Lv,Yue Gao
Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/971593
Abstract: We present a numerical method to solve the linear Fredholm integro-differential equation in reproducing kernel space. A simple algorithm is given to obtain the approximate solutions of the equation. Through the comparison of approximate and true solution, we can find that the method can effectively solve the linear Fredholm integro-differential equation. At the same time the numerical solution of the equation is stable.
Algebroid Solutions of Second Order Complex Differential Equations
Lingyun Gao,Yue Wang
Abstract and Applied Analysis , 2014, DOI: 10.1155/2014/123049
Abstract: Using value distribution theory and maximum modulus principle, the problem of the algebroid solutions of second order algebraic differential equation is investigated. Examples show that our results are sharp. 1. Introduction and Main Results We use the standard notations and results of the Nevanlinna theory of meromorphic or algebroid functions; see, for example, [1, 2]. In this paper we suppose that second order algebraic differential equation (3) admit at least one nonconstant -valued algebroid solution in the complex plane. We denote by a subset of for which and by a positive constant, where denotes the linear measure of . or does not always mean the same one when they appear in the following. Let ?? be entire functions without common zeroes such that . We put Some authors had investigated the problem of the existence of algebroid solutions of complex differential equations, and they obtained many results ([2–10], etc.).

If , then where , is a positive constant. Proof. We first prove that the poles of are contained in the zeroes of . Suppose that is a pole of of order and is not
Anisotropic magnetotransport of superconducting and normal state in an electron-doped Nd_{1.85}Ce_{0.15}CuO_{4-δ} single crystal

Physics , 2011, DOI: 10.1016/j.physc.2010.06.014
Abstract: The anisotropic properties of an optimally doped Nd_{1.85}Ce_{0.15}CuO_{4-\delta} single crystal have been studied both below and above the critical temperature Tc via the resistivity measurement in magnetic field H up to 12 T. By scaling the conductivity fluctuation around the superconducting transition, the upper critical field H_{c2}(T) has been determined for field parallel to the c-axis or to the basal ab-plane. The anisotropy factor \gamma={H_c2||ab}/{H_c2||c} is estimated to be about 8. In the normal state (50=
Stability of Brans-Dicke thin shell wormholes
Xiaojun Yue,Sijie Gao
Physics , 2011, DOI: 10.1016/j.physleta.2011.04.055
Abstract: Recently, a class of spherically symmetric thin-shell wormholes in Brans-Dicke gravity have been introduced. Such wormholes can be supported by matter satisfying the weak energy condition (WEC). In this paper, we first obtain all the exact solutions satisfying the WEC. Then we show these solutions can be stable for certain parameters. A general requirement for stability is that $\beta^2>1$, which may imply that the speed of sound exceeds the speed of light.

Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.53005
Abstract: Many studies focus on rodent community pattern and changing at present in the world, but most of them are conducted in small plots. Few studies investigated the rodent community classification and diversity in semi-desert and desert areas at regional scale, although some researchers started to study the change of animal community patterns on a large scale. We investigated rodent communities in desert, non-irrigated farming land and desert steppe of Inner Mongolia, covering an area of 380,000 km2 from May to August in 1988-1993 and in 1998-2003, respectively, in order to reveal the changing characteristics of zonal rodent communities. The community classification and diversity of rodents were analyzed in research areas. The results suggested that the communities could be classified in 9 zonal types. Spermophilus dauricus, Cricetulus longicaudatus and Eutamias sibiricus were dominant species in Community I; Phodopus roborovskii, Cricetulus barabansis and Cricetulus longicaudatus were dominant in Community II; Meriones unguiculatus, Phodopus roborovskii and Cricetulus longicaudatus
First-Principles Studies on the Structural Transition of ZnO Nanowires at High Pressure
Zhanjun Gao,Yousong Gu,Yue Zhang
Journal of Nanomaterials , 2010, DOI: 10.1155/2010/462032
Abstract: The structural transition of ZnO nanowires at high pressures from wurtzite to rocksalt structure has been studied by first-principles density functional calculations using the SIESTA code. The size effect was studied by calculating a series of nanowires with different diameters, and the doping effect was studied by ion substitution. It is found that the critical pressure of structural transition for nanowires is lower than that of the bulk, and it decreases as the diameter of the nanowire decreases. It is also found that Mn doping can reduce the transition pressure. The size effect and doping effect are discussed in terms of the chemical bonding and energies of the nanowires.
Discovery of phosphatized gastrula fossils from the Doushantuo Formation, Weng’an, Guizhou Province, China
Yin Chongyu,Yue Zhao,Gao Linzhi
Chinese Science Bulletin , 2001, DOI: 10.1007/BF02900658
Abstract: Globular fossils from Doushantuo phosphorites at the Weng’an area are for the first time identified as a gastrulation stage of phosphatized embryos. They are got from the fossiliferous remains after acetic acid maceration. The fossils are found together with formerly reported animal resting eggs and embryos of the earlier cleavage stage. The oblate-shaped fossils with the same size as those reported embryos and invaginate at the middle part into the embryos, show the characteristics of the late blastula to the early gastrula stage of the embryo development. This discovery convinces the existence of animal embryos at Doushantuo age and offers new facts for the studying of the affinity of related fossils, which are still controversial at present.
SPONTANEOUS EMISSION OF A DRIVEN FOUR-LEVEL DOPPLER BROADENED SYSTEM

Yuan Shi,Gao Jin-yue,

中国物理 B , 2000,
Abstract: We have studied the steady spontaneous emission spectrum of a four-level Doppler-broadened system driven by three coherent fields. It is found that the fluorescence spectrum is composed of nine contributions. The spectral components have quite different widths and peak heights compared with the case of the standard driven two-level or three-level resonance fluorescence. We provide numerical results in support of our arguments for arbitrary values of the atomic and field parameters.
