Empirical Study on the Integration of Native Culture in English Language Teaching for Non-English Majors in China
Cui-ping Han
English Language and Literature Studies , 2012, DOI: 10.5539/ells.v2n2p116
Abstract: The study consists of surveys concerning Chinese culture in English language teaching, which reveal the insufficiency of the input of native culture, the insufficiency of the non-English majors’ ability to express Chinese culture in English and the students’ attitude toward such insufficiency. Based on the results and analysis, it explores reasons leading to this phenomenon, elaborates the necessity of integrating native culture, and offers some suggestions on English teaching practice. By advocating the integration of native culture in English language teaching for non-English majors, the study is to improve the understanding of cross-cultural communication in culture teaching, thus promoting the cultivation of students’ cross-cultural communication competence.

Abstract: For a better understanding of the air mass exchange processes between the surface and free atmosphere in the Himalayas, a Himalayan exchange between the surface and troposphere 2007 (HEST2007) campaign was carried out in the Rongbuk Valley, on the northern slope of Mt. Qomolangma, in June 2007. The wind, temperature and radiation conditions were measured during the campaign. Using these observation data, together with the NCEP/NCAR reanalysis data, the air mass exchange between the inside of the valley and the outside of the valley is quantitatively estimated, based on a closed-valley method. The air mass is strongly injected into the Rongbuk Valley in the afternoon, which dominates the diurnal cycle, by a strong downward along-valley wind, with a maximum downward transfer rate of 9.4 cm s 1. The total air volume flux injected into the valley was 2.6×1011 m3 d 1 in 24 hours in June 2007, which is 15 times the total volume of the valley. The air mass transfer into the valley also exhibited a clear daily variation during the HEST2007 campaign, which can be affected by the synoptic situations through the adjustment of local radiation conditions.

Abstract: In this paper, we relocated earthquakes occurred around Longtan reservoir from 2006 to 2007 by using hypoDD relocation method and waveform cross-correlation technique, analyzed its seismic activity. Relocation results by applying the waveform cross-correlation technique and hypoDD method demonstrates that the earthquake location quality are obviously enhanced. Analysis of the characteristics of seismicity around Longtan reservoir proved that there is a tight correlation between the seismic activity around Longtan reservoir and the process of reservoir recharge. Earthquakes clustered around Longtan reservoir region and performed different response corresponding to water level change respectively, indicating that there may exist local differences of lithological characteristic, penetrative condition, geological structure, as well as stress field condition around the Longtan reservoir.
Placebo Analgesia, Acupuncture and Sham Surgery
Tao Liu,Cui-ping Yu
Evidence-Based Complementary and Alternative Medicine , 2011, DOI: 10.1093/ecam/neq030
Abstract: Invasive procedures, such as surgery and acupuncture, are likely better than the others in terms of eliciting placebo analgesia. Understanding how invasive procedures can elicit enhanced placebo responses may provide new insights into mechanisms underlying placebo analgesia. In this essay, it is argued that sensory, cognitive and emotional factors are major determinants of the magnitude of placebo analgesia. Sham surgery and acupuncture are good examples of placebo interventions, which generate robust placebo responses through simultaneously manipulating such three factors.

Abstract: In the summers of 2006 and 2007, the atmospheric CO2 concentration and the wind speed in the Rongbuk Valley on the northern slope of Mt. Everest were measured by an ultrasonic anemometer with an Li-7500 CO2/H2O gas analyzer. The average CO2 concentration was 370.23±0.59 and 367.45±1.91 ppm in June of 2006 and 2007, respectively. The values are much lower than those at sites with similar latitudes and altitudes worldwide. The observed atmospheric CO2 concentration in Rongbuk Valley can be affected by the transportation of prevailing down-valley winds from the up-valley direction to the observation site. Our results suggest that the Mt. Everest region could be ideal for background atmospheric and environmental studies.

Abstract: Data cube pre-computation is an important concept for supporting OLAP (Online Analytical Processing) and has been studied extensively. It is often not feasible to compute a complete data cube due to the huge storage requirement. Recently proposed quotient cube addressed this issue through a partitioning method that groups cube cells into equivalence partitions. Such an approach not only is useful for distributive aggregate functions such as SUM but also can be applied to the maintenance of holistic aggregate functions like MEDIAN which will require the storage of a set of tuples for each equivalence class. Unfortunately, as changes are made to the data sources, maintaining the quotient cube is non-trivial since the partitioning of the cube cells must also be updated. In this paper, the authors design incremental algorithms to update a quotient cube efficiently for both SUM and MEDIAN aggregate functions. For the aggregate function SUM, concepts are borrowed from the principle of Galois Lattice to develop CPU-efficient algorithms to update a quotient cube. For the aggregate function MEDIAN, the concept of a pseudo class is introduced to further reduce the size of the quotient cube. Goupled with a novel sliding window technique, an efficient algorithm is developed for maintaining a MEDIAN quotient cube that takes up reasonably small storage space. Performance study shows that the proposed algorithms are efficient and scalable over large databases.

Abstract: 本文首先阐明汶川MS8.0级地震发生在由区域布格重力异常和地震震中分布所确定的武都—松潘—茂汶—汶川—泸定地震带上.汶川地震所在地段是地震前兆和中小地震(M≤7.0)的空白区,震前出现明显的孕震空区,MS8.0级地震发生在空区周围区域中小地震活动峰值之后的减少段里.地震的破裂超出孕震空区范围,空区内、外余震活动呈现出不同的衰减特征,依此将余震活动分为WS和NE两个区段.地震破裂过程、4级以上余震矩张量及震区应力场反演和余震应力降的测定结果表明,两个区域的位错、余震机制解和应力降及最大主应力的方〖JP2〗向等明显有别.根据这些特征和地震应力触发的研究,推测NE段地震的发生可能是〖JP〗由WS段主破裂的发生所触发.

Abstract: Rabies remains a serious problem in China with three epidemics since 1949 and the country in the midst of the third epidemic. Significantly, the control of each outbreak has been followed by a rapid reemergence of the disease. In 2005, the government implemented a rabies national surveillance program that included the collection and screening of almost 8,000 samples. In this work, we analyzed a Chinese dataset comprising 320 glycoprotein sequences covering 23 provinces and eight species, spanning the second and third epidemics. Specifically, we investigated whether the three epidemics are associated with a single reemerging lineage or a different lineage was responsible for each epidemic. Consistent with previous results, phylogenetic analysis identified six lineages, China I to VI. Analysis of the geographical composition of these lineages revealed they are consistent with human case data and reflect the gradual emergence of China I in the third epidemic. Initially, China I was restricted to south China and China II was dominant. However, as the epidemic began to spread into new areas, China I began to emerge, whereas China II remained confined to south China. By the latter part of the surveillance period, almost all isolates were China I and contributions from the remaining lineages were minimal. The prevalence of China II in the early stages of the third epidemic and its established presence in wildlife suggests that it too replaced a previously dominant lineage during the second epidemic. This lineage replacement may be a consequence of control programs that were dominated by dog culling efforts as the primary control method in the first two epidemics. This had the effect of reducing dominant strains to levels comparable with other localized background stains. Our results indicate the importance of effective control strategies for long term control of the disease.
A Molecular Phylogeny of Hemiptera Inferred from Mitochondrial Genome Sequences
Nan Song,Ai-Ping Liang,Cui-Ping Bu
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0048778
Abstract: Classically, Hemiptera is comprised of two suborders: Homoptera and Heteroptera. Homoptera includes Cicadomorpha, Fulgoromorpha and Sternorrhyncha. However, according to previous molecular phylogenetic studies based on 18S rDNA, Fulgoromorpha has a closer relationship to Heteroptera than to other hemipterans, leaving Homoptera as paraphyletic. Therefore, the position of Fulgoromorpha is important for studying phylogenetic structure of Hemiptera. We inferred the evolutionary affiliations of twenty-five superfamilies of Hemiptera using mitochondrial protein-coding genes and rRNAs. We sequenced three mitogenomes, from Pyrops candelaria, Lycorma delicatula and Ricania marginalis, representing two additional families in Fulgoromorpha. Pyrops and Lycorma are representatives of an additional major family Fulgoridae in Fulgoromorpha, whereas Ricania is a second representative of the highly derived clade Ricaniidae. The organization and size of these mitogenomes are similar to those of the sequenced fulgoroid species. Our consensus phylogeny of Hemiptera largely supported the relationships (((Fulgoromorpha,Sternorrhyncha),Cicadom?orpha),Heteroptera),and thus supported the classic phylogeny of Hemiptera. Selection of optimal evolutionary models (exclusion and inclusion of two rRNA genes or of third codon positions of protein-coding genes) demonstrated that rapidly evolving and saturated sites should be removed from the analyses.
