Ever since the 1970s when Chinese American writers thrived from a marginal position and integrated into the mainstream of American literature, the study on Chinese American Literature has received more and more attention from the academic circles. However, the research on this newly emerging subject in the field of translation studies has not been treated with equal attention. This thesis attempts to propose a possible strategy to translate Chinese American works, based on the theory of "functional equivalence", taking the comparison of the 2 Chinese versions of TAN's The Joy Luck Club as an example. 展开更多

Amy Tan is a renowned Chinese American writer who has won prestigious awards and also received various criticism from home and abroad. Her first novel The Joy Luck Club has won her several prestigious literary awards. However, the limitation of Orientalism is also manifested in the novel, which leads to much criticism. It is believed that the novel is popular because the binary distinction between the East and the West satisfies the ideological needs of the white-dominated society. This thesis is trying to interpret The Joy Luck Club from the perspective of Orientalism. 展开更多

The study of accelerator-driven subcritical reactor systems(ADSs) has been an important research topic in the field of nuclear energy for years. The main code applied in ADS research is MCNPX, which was developed by Los Alamos National Laboratory. We studied the application of the open-source Monte Carlo codes FLUKA and OpenMC to a coupled ADS calculation. The FLUKA code was used to simulate the reaction of highenergy protons with the nucleus of the target material in the ADS, which produces spallation neutrons. Information on the spallation neutrons, such as their energy, position,direction, and weight, can be recorded by a user-defined routine called FLUSCW provided by FLUKA. Then, the information was stored in an external neutron source file in HDF5 format by using a conversion code, as required by the OpenMC calculation. Finally, the fixed-source calculation function of OpenMC was applied to simulate the transport of spallation neutrons and obtain the distribution of the neutron flux in the core region. In the coupled calculation, the high-energy cross-section library JENDL4.0/HE in ACE format produced by NJOY2016 was applied in the OpenMC transport simulation. The OECD–ADS benchmark problem was calculated, and the results were compared with those obtained using MCNPX. It was found that the flux calculations performed by FLUKA–OpenMC and MCNPX were in agreement, so the coupling calculation method for ADS is reasonable and feasible. 展开更多

Objective:An acute shortage of nurses exists all over the world.Part of this shortage appears to be due to nurses’low job satisfaction,low retention,and high turnover.Happiness at work is identified as a contributing factor that determines the shortage of nurses across the world.This paper critically appraised the existing scientific articles that assessed the individual and organizational predictors of happiness among nurses.Methods:The systematic review was conducted from August 2010 to August 2020 using Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines.Scientific articles were searched in the electronic databases(Scopus,Medline,CINAHL,Psych INFO,and Pubmed Central)on the predictors of happiness among nurses.Results:A total of 13 articles were selected following the literature search and a thematic analysis was done.This review provides updated evidence on the predictors of nurses’happiness.Job-related predictors were identified as organizational predictors;and personal,psychological,family,social,and spiritual predictors were reported to be the individual predictors.Conclusions:As both individual and organizational predictors determine the happiness of nurses,the authors recommend the need for future interventional studies to increase the nurses’happiness,their mental health,and health-related quality of life. 展开更多
