Enigma of Exam-oriented Education in China:A comparison on Sino-U.S.Educational Concepts in Higher Education

College English teaching in China has long been criticized for its orientation to examination that consequently brings about negative learning attitude and ineffective learning achievement.Chinese educationists have brought forward several ap proaches to solve this problem but little has been changed due to the cultural influences.This paper analyzes the roots of examoriented education system in China in perspective of culture by comparing the Sino-U.S.cultural elements in depth in tradition al culture,learning and teaching motivation,teacher-student relationship and learners'engagement in class.This paper finally poses two suggestions on how to change the current situation gradually:(1) Focus on the washback of evaluation system on edu cational concepts.(2) Transform the product-evaluation to process-evaluation gradually by standardizing the current evaluation approaches,especially the standards of process-evaluation.

The Comparison and Contrast of Skopostheorie and Baker's Equivalence Translation Approach

Equivalence can be said to be the central issue in translation although its different approaches have caused heated controversy.However,as early as the 1970s,the Skopostheorie emerged in Germany,and it seemed to challenge the equivalence theories.Although Nida and some linguistics raised some negative problems of this theory,it still rapidly became famous around the world,This article will mainly compare and analyse Skopostheorie and Baker's translation equivalence approach.First,it will give a simple overview of these two approaches.Second,it will discuss the relevant strengths and weaknesses of these two approaches in relation to their usage.Finally,it will discuss combining these two approaches in the same translation.

Photodynamic therapy vs radiofrequency ablation for Barrett's dysplasia: Efficacy,safety and cost-comparison

AIM:To compare effectiveness,safety,and cost of photodynamic therapy(PDT)and radiofrequency ablation(RFA)in treatment of Barrett’s dysplasia(BD).METHODS:Consecutive case series of patients undergoing either PDT or RFA treatment at single center by a single investigator were compared.Thirty-three patients with high-grade dysplasia(HGD)had treatment with porfimer sodium photosensitzer and 630 nm laser(130 J/cm),with maximum of 3 treatment sessions.Fifty-three patients with BD(47 with low-grade dysplasia-LGD,6 with HGD)had step-wise circumferential and focal ablation using the HALO system with maximum of 4 treatment sessions.Both groups received proton pump inhibitors twice daily.Endoscopic biopsies were acquired at 2 and 12 mo after enrollment,with 4-quadrant biopsies every 1 cm of the original BE extent.A complete histological resolution response of BD(CR-D)was defined as all biopsies at the last endoscopy session negative for BD.Fisher’s exact test was used to assess differences between the two study groups for primary outcomes.For all outcomes,a two-sided P value of less than 0.05 was considered to indicate statistical significance.RESULTS:Thirty(91%)PDT patients and 39(74%)RFA were men(P=0.05).The mean age was 70.7±12.2 and 65.4±12.7(P=0.10)year and mean length of BE was 5.4±3.2 cm and 5.7±3.2 cm(P=0.53)for PDT and RFA patients,respectively.The CR-D was(18/33)54.5%with PDT vs(47/53)88.7%with RFA(P=0.001).One patient with PDT had an esophageal perforation and was managed with non-surgical measures and no perforation was seen with RFA.PDT was five times more costly than RFA at our institution.The two groups were not randomized and had different BD grading are the limitations of the study.CONCLUSION:In our experience,RFA had higher rate of CR-D without any serious adverse events and was less costly than PDT for endoscopic treatment of BD.

Cloning and Homology Comparison of S Gene for Isolate TH-98 of Porcine Transmissible Gastroenteritis Virus

TH-98 isolate of transmissible gastroenteritis virus (TGEV) was propagated and harvested on swine testicle (ST) monolayer cell. Two pairs of primers were designed to amplify S gene by RT-PCR according to the published sequence of TGEV'S gene cDNA with Oligo version 4.1 and DNasis software. The products of PCR were named Sa and Sb, of 2.3 kb and 2.1 kb respectively. Sa was inserted in EcoR I and Kpn I sites after Sb was cloned in Kpn I and Pst I multiple cloning sites of the same pUC18 plasmid. The recombinant pUC-S plasmid was identified and analyzed by corresponding restriction endonuclease and nested PCR on the basis of the genetic sites of S gene and pUC18 plasmid, which was identified as S gene of TGEV. Recombinant pUC-S was sequenced and analyzed in comparison with the other strains. Gene sequence comparison indicated that TH-98 shared 99, 97, 98, 97 and 94% identities with Purdue-115(US), Miller(US), TO14(Japan), FS772(British), 96-1933(British), respectively, their deduced amino acid homology was 99, 97, 97, 96 and 93% correspondingly. In addition, the analysis report verified that pUC-S owned a complete open reading frame (ORF) including initiation codon, signal sequences, remaining sequences and termination codon as well. Therefore, the results affirmed that S gene of TGEV TH-98 was extremely conservative.

China's WTO Entry Helps Sino-US Ties

China applied for restoration of its status as the GATT founding member in1986. The country has made great endeavor in reducing customs duties, removing non-tariff barriers, enhancing protection of intellectual property rights andservice trades, launching reform of the foreign trade regime, eliminating trade bar-riers and improving environment for foreign investment. Over the past 14 years,China has taken part in 26 relevant multilateral meetings and hundreds of bilateralnegotiations.

Frugality and overspending:sources of Sino-U.S.economic imbalances

Savings rates are the biggest difference in the economic structures of China and the United States,the two most important countries in today’s global economy.China has the highest savings rate of any major country,while the United States,at the other end of the spectrum, has the lowest.This paper discusses the origin of this contrast and its far-reaching implications for two-way economic and trade ties.

New Sino-US Strategic Gambling and China’s Strategy

Since confidence is fading and anxiety is increasing in the US,America’s China policy has become more radical. In the short term, the US has the upper hand and China is in a relatively passive position. In the medium-and long-term, there will be more balance between them. This current strategic gambling between China and the US will be the major issue of international politics in the first half of the 21 st century and the most prominent external challenge China faces. China needs to make strategic adjustments but the gamble may be worthwhile in correcting imbalance in the international order and in the co-evolution of the two countries.

SINO-U.S.RELATIONS:AT A NEW CROSSROADS?

Report on the Translation of The Art of War——A Comparison with Giles’ Mistranslations

With the rapid development of globalization,the world is deepening the links in various areas,such as politics,trade and culture.Culture serves the spirit and soul of a nation.To promote the common prosperity of culture,the whole world should strengthen the communication and exchanges with each other.The translation of Chinese classics plays a key role in the cultural ex⁃changes.The Art of War,written by Sun Tzu in Spring and Autumn period,is the earliest work of military science extant in the world.It has expounded the military strategies from a deep insight and in a comprehensive way.The study of this book is still of great importance now since the strategies it offered can be used in various areas.The thesis is based on the first five chapters the writer has translated.Lionel Giles,M.A.’s version plays an important role in cross culture communication.However,there still ex⁃ist some mistranslations.The writer provided her understanding and offered her English version by comparison with Giles’in the hope of deepening her translation study as well as providing some reference to foreigners interested in this book and ones that are interested in translation study.

Faster than the Speed of Light Is a Quantum Phenomena

Classical Mechanics using Einstein’s theories of relativity places a limit on speed as the speed of light. Quantum Mechanics has no such limitation. To understand space accelerating faster than the speed of light and information being exchanged instantaneously between two entangled electrons separated by huge distances, one uses Planck’s length, Planck’s time, and Planck’s mass to indicate that space and time are discrete and therefore along with masses smaller than Planck’s mass are Quantum Mechanical in nature. Faster than the speed of light c = 3 × 108 m/s is a classical effect only in dimensions of space lower than our 3-D Universe, but it is a Quantum effect in all dimensions of space. Because space can oscillate sending out ripples from the source, it is the medium used for transporting light waves and gravity waves.
