功能文体学与大学英语教学     

王璐 《阜阳师范学院学报(社会科学版)》2008,(2):141-143

在大学英语教学当中,教师们往往会更多地关注词汇和语言点的教学。但是这种模式往往脱离了语境,不利于学生对于整个语篇的把握,不利于培养学生的综合语言运用能力。本文通过对《新编大学英语》第一册第四单元的课文"Fresh Start"的功能文体分析指出,功能文体分析可以更好地解释和解读课文,也有利于提高学生的语言理解能力和鉴赏能力。  相似文献   

“三个代表”：马克思主义建党学的创新     

聂资鲁 《淮阴师范学院学报(哲学社会科学版)》2001,23(4):421-425

江泽民关于“三个代表”的理论,即源于马克思主义、又是对马克思主义建党学说的发展。“三个代表”理论的贡献体现了鲜明的时代性、创新性和前瞻性。作为从现实生活中汲取营养的理论之树,“三个代表”是指导新世纪中国现代化进程中党的建设的战略性纲领。  相似文献

Improving students' pronunciation through accent reduction software     

Gölge Sefero&#;lu 《British journal of educational technology : journal of the Council for Educational Technology》2005,36(2):303-316

This study aimed to find out whether integrating accent reduction software in advanced English language classes at the university level would result in improvements in students’ pronunciation at the segmental and sup‐rasegmental levels. The study made use of a quasi‐experimental research design. Two classes at the Department of Foreign Language Education at Middle East Technical University in Turkey participated in the study. Whilst one class (the control group) followed traditional instruction, the other class (experimental group) followed instruction which integrated use of accent reduction software in a multimedia language laboratory. Based on the results of the study, it is suggested that especially in English as a Foreign Language (EFL) settings where natural target language input is scarce, technology has a lot to offer, and EFL learners may be provided with exposure and practice/interaction opportunities in the target language through specifically designed software programs.  相似文献   

“绿色条款”在实践中的新发展与绿色贸易壁垒——从WTO争端解决实践看GATT第20条     

高晓露 《信阳师范学院学报(哲学社会科学版)》2003,23(4):46-49

在WTO争端解决实践中,GATT第20条“绿色条款”的适用范围有了许多新发展：可适用于基于产品生产工艺、生产方法而采取的措施;可适用于为保护生物资源而采取的措施;也可适用于与保护可用竭自然资源这个合法目标之间有实际联系的措施。“绿色条款”在实践中的新发展极易被新贸易保护主义滥用,从而为绿色贸易壁垒提供合法的“多边外衣”。  相似文献   

The effect of extremely high glucose concentrations on 21 routine chemistry and thyroid Abbott assays: interference study

Introduction

Extremely high glucose concentrations have been shown to interfere with creatinine assays especially with Jaffe method in peritoneal dialysate. Because diabetes is the fastest growing chronic disease in the world, laboratories study with varying glucose concentrations. We investigated whether different levels of glucose spiked in serum interfere with 21 routine chemistry and thyroid assays at glucose concentrations between 17-51 mmol/L.

Materials and methods

Baseline (group I) serum pool with glucose concentration of 5.55 (5.44-5.61) mmol/L was prepared from patient sera. Spiking with 20% dextrose solution, sample groups were obtained with glucose concentrations: 17.09, 34.52, and 50.95 mmol/L (group II, III, IV, respectively). Total of 21 biochemistry analytes and thyroid tests were studied on Abbott c8000 and i2000sr with commercial reagents. Bias from baseline value was checked statistically and clinically.

Results

Creatinine increased significantly by 8.74%, 31.66%, 55.31% at groups II, III, IV, respectively with P values of < 0.001. At the median glucose concentration of 50.95 mmol/L, calcium, albumin, chloride and FT4 biased significantly clinically (-0.85%, 1.63%, 0.65%, 7.4% with P values 0.138, 0.214, 0.004, < 0.001, respectively). Remaining assays were free of interference.

Conclusion

Among the numerous biochemical parameters studied, only a few parameters are affected by dramatically increased glucose concentration. The creatinine measurements obtained in human sera with the Jaffe alkaline method at high glucose concentrations should be interpreted with caution. Other tests that were affected with extremely high glucose concentrations were calcium, albumin, chloride and FT4, hence results should be taken into consideration in patients with poor diabetic control.Key words: assay interference, glucose interference, preanalytical phase, creatinine, Jaffe kinetic assay, thyroid function tests  相似文献   

A stochastic multi-parameters divergence method for online auto-tuning of fractional order PID controllers     

Celaleddin Yeroğlu  Abdullah Ateş 《Journal of The Franklin Institute》2014

This paper presents a stochastic multi-parameters divergence method for online parameter optimization of fractional-order proportional–integral–derivative (PID) controllers. The method is used for auto-tuning without the need for exact mathematical plant model and it is applicable to diverse plant transfer functions. The proposed controller tuning algorithm is capable of adaptively responding to parameter fluctuations and model uncertainties in real systems. Adaptation skill enhances controller performance for real-time applications. Simulations and experimental observations are carried on a prototype helicopter model to confirm the performance improvements obtained by the online auto-tuning of fractional-order PID structure in laboratory conditions.  相似文献
