ELT TEACHERS’ ROLE WITHIN E-LEARNING AND COMMUNICATIVE TEACHING FROM STUDENTS’ PERCEPTIONS  [PDF]
Xie Jie, Zhang Genlin
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.37b040
Abstract: The present thesis aims to empirically determine the effects of technology, specifically the integration of e-learning within English language teaching, on students’ perception of teachers’ role. Participants were divided into experimental (e-learning) E-group and controlled (traditional) T-group. SPSS was used to analyze the data collected. The results show that, in both groups, students’ perceptions of the teachers’ role remain positive form the beginning of the term to the end. Such findings reveal that the role of ELT teachers within e-learning is analogous to an interactive teacher of the earlier conventions, a multifaceted one with strategy-oriented tasks ranging from Facilitation, Advising, Conducting experiments, Engineering activities, to Supporting divergent learning styles, pathways and creative productions (FACES). However, in the aspects of giving advice, offering educational and technological support and engineering various activities, e-learning group of students holds more positive attitude than the traditional group.

Review of Chinese and Foreign Management Accounting Research—Based on Management Accounting Research Topics and Research Methods  [PDF]
Jie Xie
Open Journal of Social Sciences (JSS) , 2019, DOI: 10.4236/jss.2019.712009
Abstract: This paper takes 71 management accounting documents published in the 2015-2017 mainstream journals as a sample, systematically combs, summarizes and reviews the management accounting research topics and research methods. We find that the subject of management accounting research is increasingly diversified, with performance evaluation and measurement, compensation and incentive research being the most popular. There are obvious differences in research methods at home and abroad. Among them, domestic research mainly focuses on data-based empirical analysis and normative research, while foreign literature research methods prefer experimental research methods. I hope that the comparative analysis of the article can provide reference for the research and development of domestic management accounting.
Comparative sequence analysis reveals an intricate network among REST, CREB and miRNA in mediating neuronal gene expression
Jie Wu, Xiaohui Xie
Genome Biology , 2006, DOI: 10.1186/gb-2006-7-9-r85
Abstract: Using comparative sequence analysis, here we report the identification of 895 sites (NRSE) as the putative targets of REST. A set of the identified NRSE sites is present in the vicinity of the miRNA genes that are specifically expressed in brain-related tissues, suggesting the transcriptional regulation of these miRNAs by REST. We have further identified target genes of these miRNAs, and discovered that REST and its cofactor complex are targets of multiple brain-related miRNAs including miR-124a, miR-9 and miR-132. Given the role of both REST and miRNA as repressors, these findings point to a double-negative feedback loop between REST and the miRNAs in stabilizing and maintaining neuronal gene expression. Additionally, we find that the brain-related miRNA genes are highly enriched with evolutionarily conserved cAMP response elements (CRE) in their regulatory regions, implicating the role of CREB in the positive regulation of these miRNAs.The expression of neuronal genes and neuronal identity are controlled by multiple factors, including transcriptional regulation through REST and post-transcriptional modification by several brain-related miRNAs. We demonstrate that these different levels of regulation are coordinated through extensive feedbacks, and propose a network among REST, CREB proteins and the brain-related miRNAs as a robust program for mediating neuronal gene expression.Regulation of gene expression is critical for nervous system development and function. The nervous system relies on a complex network of signaling molecules and regulators to orchestrate a robust gene expression program that leads to the orderly acquisition and maintenance of neuronal identity. Identifying these regulators and their target genes is essential for understanding the regulation of neuronal genes and elucidating the role of these regulators in neural development and function.The transcriptional repressor REST (RE1 silencing transcription factor, also called neuron-restrictive sil
A Burning Experiment Study of an Integral Medical Waste Incinerator  [PDF]
Rong Xie, Jidong Lu, Jie Li, Jiaqiang Yin
Energy and Power Engineering (EPE) , 2010, DOI: 10.4236/epe.2010.23026
Abstract: Mass burning of the medical waste is becoming attractive in China because Chinese government has banned landfilling of medical waste. Many advantages can be found in this method, such as reduction in waste volume, destruction of pathogens and transformation of waste into the form of ash. However, the medical waste with high moisture in China is not suitable to be treated in the present direct mass burning incinerators. In this paper, a novel integral incinerator is developed with combining a feeder, a rotary grate, a primary combustion chamber (PCC) and a “coaxial” secondary combustion chamber (SCC) into a unique unit. Its capability is 10 ton/day. As the air excess level in the PCC was only 40% stoichiometric ratio, the PCC acted as a gasifier. The 1.0 excess air ratios in the SCC preserved the purpose of full combustion of flue gas. Temperature and pollutants concentration in the SCC were measured to understand the combustion behavior of volatile organics. Emission concentrations of pollutants before stack were also tested and compared with the China National Incineration Emission Standard.
Amino terminus mutant OmpA from an isolated antibiotic resistant Escherichia coli still possess resistance to environmental stresses  [PDF]
Zhiping Zhao, Xin Nie, Zaixin Li, Zhi Zhang, Jie Ding, Wanru Xie
Advances in Biological Chemistry (ABC) , 2013, DOI: 10.4236/abc.2013.31014
Abstract:

Antibiotic resistant Escherichia coli strains are becoming more common recently. OmpA is a very important antigen protein of E. coli, which consists of two separate domains, N-terminal and C-terminal domain. The N-terminal domain contains eight β- barrel regions that plays important roles in the multifaceted functions of OmpA. In the present study, we cloned a mutant OmpA gene from a multi-antibiotic resistant E. coli strain. Sequence analysis indicated that the N-terminal DNA sequence of the mutant OmpA shared 81.05% homology with the modeled OmpA from E. coli K12 and the N-terminal amino acid sequence of the mutant OmpA was 81.22% identical to that of the E. coli K12 OmpA. Moreover, several amino acids located in the β-barrel region were mutated. The mutant OmpA was expressed in BL21 suggested by SDS-PAGE. Resistance to environmental stress assay indicated that the N-terminus mutant OmpA still possessed excellent activities in pH, temperature and osmotic pressure resistance. Our pre- sent study may supply insights into better and deeper understand the relationships between OmpA N-terminal regions and its functions in environmental stress conditions and the mechanisms on antibiotic resistance of E. coli.

Jie Guo,Xin Liu,Qiang Xie
Chinese Science Bulletin , 2013, DOI: 10.1007/s11434-012-5355-0
Abstract: In this paper, ENVISAT ASAR data and the Estuary, Coastal and Ocean Model was used to analyze and compare characteristics of the Bohai Sea oil spill. The oil slicks have spread from the point of the oil spill to the east and north-western Bohai Sea. We make a comparison between the changes caused by the oil spill on the chlorophyll concentration and the sea surface temperature using MODIS data, which can be used to analyze the effect of the oil spill on the Bohai Sea ecosystem. We found that the Bohai Sea oil spill caused abnormal chlorophyll concentration distributions and red tide nearby area of oil spill.
Analysis of Volatile Compounds and Identification of Characteristic Aroma Components of Toona sinensis (A. Juss.) Roem. Using GC-MS and GC-O  [PDF]
Changjin Liu, Jie Zhang, Zhongkai Zhou, Zetian Hua, Hongying Wan, Yanhui Xie, Zhiwei Wang, Li Deng
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.43041
Abstract:

In this study, volatile compounds present in Toona sinensis (A. Juss.) Roem (TS) were investigated and their characteristic aromatic components were identified using Headspace Solid-phase Microextraction (HS-SPME) followed by Gas Chromatography-Mass Spectrometry (GC-MS) and Gas Chromatography-Olfactometry (GC-O). The optimum conditions for extracting the volatiles from TS were achieved with the experimental parameters including the use of a 65 μm polydimethylsiloxane/divinyl benzene (PDMS/DVB) fibre, an extraction temperature of 40 and an extraction time of 30 min. Under these conditions, 56 volatile compounds were separated and 53 were identified by GC-MS. Among them, 21 sulfide compounds (42.146%) and 27 terpenes55.984%) were found to be the major components. The sample was analyzed by GC-O and 26 elutes were sniffed and their sensory descriptions evaluated by an odor panelists. Analysis of the data indicated, two compounds cis and trans isomers of 2-Mercapto-3,4-dimethyl-2,3-dihydrothiophene were major contributors to the characteristic aroma of TS.

Yang Wang, Jie Xu, Limin Jia, Jianyuan Guo, Ping Liang, Bo Wang, Jinxin Xie
Journal of Intelligent Learning Systems and Applications (JILSA) , 2013, DOI: 10.4236/jilsa.2013.54030
Abstract:

With the increase of Beijing urban rail transport network, the structure of the road network is becoming more complex, and passengers have more travel options. Together with the complex paths and different timetables, taking the last train is becoming much more difficult and unsuccessful. To avoid losses, we propose feasible suggestions to the last train with reasonable selling tickets system.

The Role of Pharmacists in Perioperative Antibiotic Application in a Hospital of Traditional Chinese Medicine (TCM)  [PDF]
Ruifang Xie, Zhicheng Li, Lingqi Zhu, Yun Zhang, Jie Shen, Xin Zhou
Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.53030
Abstract:

Objective: To determine adherence to Chinese guidelines for perioperative antibiotic use in our hospital of TCM and discuss the role of pharmacists on antibiotic management. Methods: 2844 operative cases between May 2011 and December 2011 in our hospital were investigated by pharmacists and relative data were collected, including demographic data, type of surgery, wound classification (clean and clean contaminated) and parameters of antibiotic application (antibiotic choice, route, dose, time of first dose, time of operative re-dosing and duration of prophylaxis). The rationality of antibiotic administration in these cases was respectively evaluated based on Chinese guidelines for perioperative antibiotic use. Results: After intervention of pharmacists, perioperative antibiotic application in our hospital was obviously improved from May to December of 2011: the rates of antibiotic application in operative cases and antibiotic prophylaxis in clean operation were both decreased. However, there was no significant improvement for the rate of rationality. In detail, TCM surgery was well compliant with the guidelines: the rate of antibiotic application was less than 30%, regimen of antibiotic prophylaxis and therapy was reasonable; in the breast ward, antibiotic application was improved after pharmacists intervention: the rate of antibiotic prophylaxis in clean operation significantly decreased from 100% to 30%; however, in the anorectal ward, some troubles were resolved while other new problems came out; in other ward such as general surgery and orthopedics, old problems still existed. Conclusions: Protocol violations were frequent to perioperative antibiotic application in our hospital due to considerable over prescription. Intervention was effective but not enough. Further educational strategies are essential for reducing costs and antibiotic resistance rates.
