A Critical Discourse Analysis of Barack Obama’s Speeches
Junling Wang
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.3.254-261
Abstract: The Critical Discourse Analysis is often applied to analyze political discourse including the public speech, in which the speaker wins favorite response from the audience. This paper, based on Critical Discourse Analysis theory and Systematic Functional Linguistics, analyzes Barack Obama’s presidential speeches mainly from the point of transitivity and modality, in which we can learn the language how to serve the ideology and power. Moreover, we can have a better understanding of the political purpose of these speeches.

Shouzheng WANG, Junling LI
- , 2016, DOI: : 10.3779/j.issn.1009-3419.2016.10.09
Abstract: In recent years, squamous non-small cell lung cancer (NSCLC) didn’t progress much in chemotherapy or target therapy. However, immunotherapy has made breakthroughs in treating squamous NSCLC. Immunotherapy includes two main broad classes of immune checkpoint inhibitors and therapeutic vaccines. Immune checkpoint inhibitors, including anti cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) and anti programmed death receptor 1 (PD-1) antibodies, have been tested in the phase II/III clinical trials and have demonstrated promising outcomes. Immunotherapy will become an important treatment for squamous NSCLC.

Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.711068
Abstract: We focused on the need for the phosphorus removal in water plant process. As for surface water plant, the enhancement of phosphorus removal in purification process can raise the biological stability of effluent potable water. This study conducted the effect of two water treatment processes for phosphorus removal, including the PAC + AAL (the treatment process using poly aluminum chloride and activated aluminum oxide) and PFS + AAL (the treatment process using poly ferric sulfate and activated aluminum oxide). The aim is to use the adsorption capacity of activated aluminum oxide to increase the removal of phosphorus in filtration process. The result showed that the two processes both can remove the phosphorus concentration to reach below 10 μg/L, and the PAC + AAL is the better process.
Adsorption Capacity for Phosphorus Comparison among Activated Alumina, Silica Sand and Anthracite Coal  [PDF]
Junling WANG, Yajun ZHANG, Cuimin FENG, Junqi LI, Guibai LI
Journal of Water Resource and Protection (JWARP) , 2009, DOI: 10.4236/jwarp.2009.14031
Abstract: Experimental researches on adsorptive capacity of activated alumina, silica sand and anthracite coal for phosphorus were conducted. Results showed that performances of three filter media were all in line with Langmuir isotherm, and activated alumina adsorptive performance was much better than silica sand and an-thracite coal for phosphorus removal. The adsorptive capacity of activated alumina, silica sand and anthracite coal for phosphorus was 3333μg/g, 49μg/g and 100μg/g respectively. Activated alumina displayed adsorp-tive function well for phosphorus, because its inner porosity, specific surface area and surface isoelectric pH value were all higher than those of other two filter media. While activated alumina was used as filter material in water treatment process, phosphorus would be removed strongly because of adsorptive characteristic of activated alumina.

Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.610085
Abstract:

That phosphorus has been removed more from water in purification process can result in higher grade of biological stability of the effluent tap water, especially for the water plant when using surface water source. This study conducted the experiments of phosphorus removal by three coagulants including aluminum chloride, aluminum sulfate and poly aluminum chloride. The results indicated that the poly aluminum chloride is the preferred one that could remove phosphorus up to 80%, followed by aluminum chloride and aluminum sulfate. The lowest proportion of aluminum quality to phosphorus quality is 63 as using poly aluminum chloride, followed by aluminum chloride and aluminum sulfate. It is suggested that the poly aluminum chloride should be the best option to remove phosphorus in water plant.

Spin polarized parametric pumping
Wu Junling,Baigeng Wang,Jian Wang
Physics , 2002,
Abstract: We have developed a general theory for a parametric pump consisting of a nonmagnetic system with two ferromagnetic leads whose magnetic moments orient at an angle $\theta$ with respect to each other. In this theory, the leads can maintain at different chemical potential. As a result, the current is driven due to both the external bias and the pumping potentials. When both $\theta$ and external bias are zero, our theory recovers the known theory. In particular, two cases are considered: (a). in the adiabatic regime, we have derived the pumped current for arbitrary pumping amplitude and external bias. (b). at finite frequency, the system is away from equilibrium, we have derived the pumped current up to quadratic order in pumping amplitude. Numerical results show interesting spin valve effects for pumped current.

Abstract: Performance management is a durative intercommunication process, and psychological contract is unwritten concealed contract between organization and employee, which is a sort of subjective understanding and apperception. Through deep analysis of the effect of performance communication on performance management and psychological contract, this article puts forward the psychological contract violation communication model based on performance communication on the base of the psychological contract violation development model, and makes performance communication exert double functions that enhance the performance of organization and amend psychological contract among organizational members.
Utility-Based Node Cooperation Mechanism in Wireless Sensor Networks  [PDF]
Xiaohui Lin, Junling Zhang, Can Hu, Yide Huang, Bin Chen, Ning Xie, Hui Wang
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2013, DOI: 10.4236/ijcns.2013.65026
Abstract:

In wireless sensor networks, due to the energy and resource constraints, nodes may be unwilling to forward packets for their neighbors. This can render severe deteriorations in the network performance and malfunctions of the system. To tackle such selfish behaviors and enhance the cooperation among sensors, based on reputation and energy consumption of each node, we present a utility function to punish the malicious nodes and encourage cooperation among nodes. Specifically, we firstly give a mixed strategy Nash equilibrium solution for the two nodes. Then we extend the model to multi-nodes scenario. With the unity function, each sensors reputation is evaluated according to its degree of cooperation. The extensive simulation results have shown the effectiveness of the mechanism, in that the cooperative behaviors are encouraged, which can ensure the normal functioning of the network system.

Yaling Liu, Pengfei Zhang, Ru Zhang, Meiling Song, Fengbo Liu, Wenquan Wang, Junling Hou
Advances in Bioscience and Biotechnology (ABB) , 2016, DOI: 10.4236/abb.2016.710037
Abstract: Radix Astragali has been an important traditional Chinese herbal medicine for over 2000 years. It is derived from two plant species, namely, Astragalus mongholicus [Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao] and Astragalus membranaceus [Astragalus membranaceus (Fisch.) Bge.] (Leguminosae ), according to the Pharmacopoeia of the People’s Republic of China. In this study, the genetic diversity and genetic relationships of Radix Astragali in China were analyzed by Inter-Simple Sequence Repeat (ISSR) markers. A total of 25 highly polymorphic ISSR primers were selected to amplify 95 Radix Astragali samples. Among 273 DNA bands amplified, 213 are polymorphic (percentage of polymorphic bands: 78%). The average value of the amplified bands was 10.9 for each primer, and the number varied from 4 to 20. The genetic diversity of the 95 Radix Astragali samples was analyzed by using POPGENE 1.32 software. The Nei’s genetic diversity index (h) and Shannon’s information index (I ) were 0.3590 and 0.5308, respectively, which indicated the abundant genetic diversity of Radix Astragali . The level of genetic diversity in A. membranaceus (h: 0.3109, I : 0.4657) was slightly lower than that in A. mongholicus (h: 0.3364, I : 0.4969). Considering the average genetic similarity coefficient by NTSYS analysis to cluster the A. membranaceus of nine habitats and A. mongholicus of five habitats, Radix Astragali samples were clustered into two groups according to place of origin. This clustering is different from traditional clustering, which divides groups according to species. Results obtained from this study will provide a theoretical basis for the molecular study on germplasm resources of Radix Astragali .

BMC Public Health , 2013, DOI: 10.1186/1471-2458-13-100
Abstract: We tested the Information--Motivation--Behavioral Skills (IMB) model in a sample of Chinese adults with Type 2 diabetes.A cross-sectional study of 222 Chinese adults with type 2 diabetes was conducted in a primary care center. We collected information on demographics, provider-patient communication (knowledge), social support (motivation), self-efficacy (behavioral skills), and diabetes self-care (behavior). The values of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were also obtained. Measured variable path analyses were used to the IMB framework.Provider-patient communication (beta = 0.12, p = .037), and social support (beta = 0.19, p = .007) and self-efficacy (beta = 0.41, p < .001) were independent, direct predictors of diabetes self-care behavior. Diabetes self-care behaviors had a direct effect on TC/HDL-C (beta = -0.31, p < .001) and LDL-C/HDL-C (beta = -0.30, p < .001).Consistent with the IMB model, having better provider-patient communication, having social support, and having higher self-efficacy was associated with performing diabetes self-care behaviors; and these behaviors were directly linked to lipid control. The findings indicate that diabetes education programs should including strategies enhancing patients' knowledge, motivation and behavioral skills to effect behavior change.
