Enlightenment of the Critical Period Hypothesis for the Early English Education

Whether children should learn English as early as possible has been a controversial topic, and one of the focal point is the credibility of the critical period hypothesis.Does critical period hypothesis really exist?How does child's age factor influence English acquisition?Analyzing the problems existing in the early English education based on the critical period hypothesis theory, secondly, investigating child's characteristics and psychological characteristics based on a case study.The research results show that learning English is not the sooner the better; the emphasis is how to ensure the quality.We should Specify children's English education market, and providence environment of language acquisition, attach great importance to the interest, and give full play to children in different stages of learning advantage.Parents and society should correctly treat the early English education, reduce misunderstanding and promote the healthy development of children's English education.

On the Feasibility of Early-age English learning

Children's English learning in China attracts more and more people's attention and is on the tendency of starting at an early age. Under the trend of "learning English from childhood", the author has explored the Critical Period Hypothesis and discussed the younger learners' disadvantages and older learners' advantages when learning English. and concludes that early-age English learning is not feasible.

Early warning of coal dynamic disaster by precursor of AE and EMR"quiet period"

Efcient and accurate monitoring and early warning of coal dynamic disaster and other disasters can provide guarantee for the efcient operation of mine transportation system.However,the traditional threshold early warning method often fails to warning some accidents.To address above issues,a new early warning method was proposed based on"quiet period"phenomenon of AE and EMR during fracture.It is found that,a"quiet period"of AE and EMR was present before the load reaches the peak stress,which could be used as one of the precursors to warn the imminent failure of coal and rock specimens.MS and AE signals increased abnormally followed by the phenomenon of"quiet period"before the occurrence of coal dynamic disaster on site,and the decrease of MS events in the"quiet period"is about 57%–88%compared with that in previous abnormal increase stage.During the damage evolution of coal and rock,"quiet period"phenomenon usually occurred at 85%–90%of the peak stress,where the slope of damage parameter curve is almost zero.The"quiet period"of the AE-EMR signals and the low change rate of damage parameter before failure provide a theoretical foundation for the coal dynamic disaster warning based on the"quiet period"precursor found in MS-AE-EMR monitoring system.These fndings will help reduce the number of under-reported events and improve early warning accuracy.

Origin of Qipao Fashion in Early Republic Period

The goal of this research is to analyze and discuss the origin of Qipao as women's fashionable wear in the early Republic Period (1911-1949).The origin of Qipao fashion will be discussed in three aspects:1) discussion of the original time,place and consumer group of Qipao fashion;2) analysis of initial style and wear combination of Qipao,3) deduction of the origin of the name Qipao.Besides,the analysis will also be given about Qipao's aesthetic characters,its production,consumption guarantee as well as its social backgrounds.The research will be made on the basis of the principles and methods of history,social psychology of clothing and design,and will use many materials especially historical writings and publications to give a more detailed discussion.Here are some tentative conclusions. Firstly, Qipao as a kind of one-piece dress was not inherited directly from the robe of Banner Style. It was a new fashion in the 1920s, which combined the elements of long vest called Qipao Majia, Wenming Xin Zhuang and the Western dress. Secondly, the Shanghai female students were the pioneering group wearing Qipao in 1925. Thirdly, the gradual acceptance of Qipao was mainly due to its aesthetic characters, production, consumption as well as social backgrounds at that time. And it was the kind of daily wear of many Chinese women after 1927. Fourthly, since Qipao represents the special clothing which integrated Chinese traditional style and the Western fashion in the early Republic Period, Qipao is advised to be taken as a special term to take the place of the previous ones like Mandarin Dress, Chipau and Cheongsam and so on.

An unusual homing behavior found in the Sichuan Partridge during the early brooding period

In this study,we report an unusual homing behavior of the Sichuan Partridge(Arborophila rufipectus)at the Laojunshan National Nature Reserve,Sichuan Province,China.Hen Sichuan Partridges led the chicks back to the nests where they hatched in the evening and roosted there over night.This behavior lasted 6.7±4.3 nights(range=1–15;n=13)after the chicks hatched.At this stage,the hens became very vigilant to predators and human disturbance.If disturbed,they often abandoned the nests immediately and no longer returned thereafter.The ambient temperature at night during the early brooding period of Sichuan Partridge at our study site was^12.4°C.Our findings suggest that hen Sichuan Partridges may make trade-offs between nest predation risks versus the thermoregulatory needs of their young.

Research on the Influence of Early Experience on the Growth Rate of Science and Engineering Graduate Supervisors

This research is based on three northeastern double first-class polytechnic universities.A total of 1628 science and engineering graduate supervisors?resumes were referred to from an official website by the random sampling method,of which only 500 supervisors were included in consideration of complete information,key events,and time in terms of the educational background(undergraduate school,graduate school,doctoral school,number of masters,number for Dr.),early work background(number of postdocs,number of overseas visits,numbers of research work),and the growth rate(period from graduation to associate professor title).The higher education background and early work background were defined as early experience,and the database of these 500 science and engineering graduate supervisors with complete resume information from three double first-class universities in northeastern China was established.In this study,the growth rate of the growth period was divided into two at the critical period:the growth rate of the graduate supervisor to associate professors.Through stepwise multiple regression analysis,it was found that higher education background(undergraduate schools,graduate schools,doctoral schools,as well as the number of master's and doctorate degrees)as well as early work background(number of postdoctoral work,research work,and overseas visits)have a significant impact on the growth rate of graduate supervisors to associate professors.

Geometric investigation of entrance proportions of houses from the Qajar to the beginning of the early Pahlavi in Dezful City(1789—1979)

Due to the importance of the historical context of Dezful City,investigating historic buildings is necessary.But unfortunately,a large part of it is being destroyed.For this reason,it is essential to discover the guidelines and logic behind the architectural design of these buildings to help their reconstruction or restoration.Regrettably,there is no logical information about the components of this context and the reconstructions are usually done according to taste and based on architecture tested or personal preference.Therefore,it is necessary to find a logic behind these critical components that support the whole plan or parts of it in a particular style.The purpose of this research is to discover and find the logic behind the design of this building in the historical context of Dezful.Finding geometrical proportions can significantly help to reconstruct buildings better and more accurately.For this purpose,30 historical houses of Dezful were randomly selected,and their input information was drawn in 2D form in AutoCAD.Then,the length,width,and height proportions were measured,and the obtained ratios were compared with the golden proportions and dynamic rectangles.This paper studies entrance based on ratios of√2,√3,√4,√4,√1.25 andφ(the golden section).The results show that golden proportions and proportions derived from dynamic rectangles are present in the wording of all cases.Moreover,the range of ratios in the plan is from 1.34 to 2,and the content of changes in the section is from 1.22 to 2.The results can help architects,and particularly building owners,to reconstruct based on existing logic by discovering the proportions of the entrances of the houses.It is possible to administer a part of the damaged tissue and estimate its dimensions and sizes because the proportions’completeness can help revive half-destroyed historical buildings.

Paleoclimate Changes during the Early Oligocene in the Hoh Xil Region, Northern Tibetan Plateau

Sedimentological, cyclic-stratigraphic, paleomagnetic, and clay-mineralogical studies on the early Oligocene Yaxicuo Group in the Hoh Xil Basin, the largest Cenozoic sedimentary basin in the hinterland of the Tibetan Plateau, provide abundant information of paleoclimate changes. A 350-m thick section in the middle-lower Yaxicuo Group was analyzed to reveal the climatic history that occurred in the Hoh Xil region during the early Oligocene interval 31.30-30.35 Ma, dated with the paleomagnetic chronostratigraphy. The results indicate that arid and cold climate dominated the Hoh Xil region during the early Oligocene in general, being related to the global cooling and drying events that occurred in the earliest Oligocene. Within this period, relatively warm and wet climate accompanied by strong tectonic activity occurred in the 31.05-30.75 Ma interval; while arid and cold climate and relatively inactive tectonics occurred in the 31.30-31.05 and 30.75-30.35 Ma intervals. Furthermore, spectral analyses of high-temporal resolution paleoclimatic records show orbital periods including eccentricity, obliquity, and precession. It is concluded that paleoclimate changes during the early Oligocene in the Hoh Xil region were forced by both tectonic activity and orbital periods.

Metallogenic Mechanism and Tectonic Setting of Tungsten Mineralization in the Yangbishan Deposit in Northeastern China

The Yangbishan iron-tungsten deposit in the Shuangyashan area of Heilongjiang Province is located in the center of the Jiamusi Massif in northeastern China. The rare earth element and trace element compositions of the scheelite show that it formed in a reducing environment and inherited the rare earth element features of the ore-forming fluid. The geochemical characteristics of the gneissic granite associated with the tungsten mineralization show that the magma formed in this reducing environment and originated from the partial melting of metamorphosed shale that contained organic carbon and was enriched with tungsten. In addition, in situ Hf isotopic analysis of zircons from the gneissic granite indicates that they probably originated from the partial melting of a predominantly Paleo-Mesoproterozoic crustal source. According to LA-ICP-MS zircon dating, the Yangbishan ore- related gneissic granite has an Early Paleozoic crystallization age of 520.6 ＋ 2.8 Ma. This study, together with previous data, indicates that the massifs of northeastern China, including Erguna, Xing＇an, Songliao, Jiamusi, and Khanka massifs, belonged to an orogenic belt that existed along the southern margin of the Siberian Craton during the late Pan-African period. The significant continental movements of this orogeny resulted in widespread magmatic activity in northeastern China from 530 Ma to 470 Ma under a tectonic setting that transitioned from compressional syn-collision to extensional post- collision.

CHINESE LADY'S DAILY WEAR IN LATE QING DYNASTY AND EARLY REPUBLIC PERIOD

The goal of this research is to describe and analyze women’s wear in the late Qing Dynasty andearly Republic Period(late 19th c.—early 20th c.),with an emphasis on the daily informal orsemi-formal wear,though some formal or ceremonial costumes such as wedding dress will also beincluded.This study will use Chinese costumes and textiles from many museums to fill in theblanks left by previous research and to give a more detailed and accurate description.It will alsouse historical documents to find the original names of these items and to illustrate a general conceptof their usage on different occasions.The different categories of women’s wear will be described in the following order:①robes orcoats;②jackets;③waistcoats or vests;④skirts;⑤pants and leggings;⑥shoes and socks;⑦headdresses;and⑧others.Of every category,the textiles,decoration,cut,form,style,colourand motif will be discussed.The way in which these items were combined will also be discussed.The comparison between women’s wear and men’s wear,women’s and children’s informal andformal dress will be given.Here are some tentative conclusions.First,the Manchu and Han style coexisted and mixedwith each other and were worn by both Manchu and Han women.Second,the basic silhouettesand cuts were relatively stable and conventional,while the decorations and details(openings,fasten-ings,pleats,vents,collars and hemlines)were different.The former represented accepted socialstandards while the latter could be a matter of personal taste.Third,women’s wear in that periodwere highly stylized,miscellaneous,elaborate,detailed,multicolored and multi-thematic.

A Typical Production and Elimination Process of Particles in Beijing during Early 2008 Olympic Games

[Objective] The aim was to discuss he produce and elimination rules of particles in Beijing during early 2008 Olympic Games. [Method] Based on the analysis of particulate matter online observation data and meteorological data during the corresponding period in Chinese environmental science college, Hysplit Back trace model and Numerical weather prediction graphs, and combined with the different analytical methods on meteorological flow fields, a typical process of particles in Beijing during early 2008 Olympic Games was studied. [Result] The results indicated that during the ascent stage of PM2.5 concentration, the PM showed gradually aging phenomena; the process controlled by large scale synoptic system mainly. And the weak wind and the high humidity were not in favor of dispersion; the prolonged southerly air mass to bring the pollutant of Hebei, Taijin and Shandong to Beijing; mixing height and temperature curve took the importance role to the pollution. [Conclusion] The study provided theoretical basis for the discussion on factors influencing the production and elimination of particles in the air pollution process.

Social Classes and Cultural Connotations of Yangzhou Home Gardens during the Late Qing Dynasty and the Republic of China

During the late Qing Dynasty and the early period of the Republic of China(1870-1930),the social classes in Yangzhou were basically dominated by officials,businessmen,and scholars.In the building number,scale,and functional evolution of their home gardens,these three classes were different,reflecting abundant connotation of characteristic of the time and regional culture,revealing the inheritance path of Yangzhou culture,as well as the richness and diversity of home gardens in Yangzhou during the late Qing Dynasty and the early period of the Republic of China.

＂Trades＂ and ＂Social Membership＂ into the Context of Feudal Friulian Society during Late Middle Ages （13th Century- 1511）

It is a very hard job for historians to keep themselves neutrals in from of the events they find during their studies. It is also difficult to notice the correlations among the different times of the history without falling in anachronistic mistakes. In fact, it is well-known that a historian must be wise and rational when he finds those correlations, because every society has its own characteristics, structures, and mentality. This brief essay focuses on the social structures in a north eastern italic region, which is called Friuli, between the 12th and 16th centuries. In the above mentioned centuries, it is possible to notice an evolution from a feudal ecclesiastical principality, ruled by prince-patriarchs, ecclesiastical institutions and nobility, to a more fluid and dynamic constitution formed by new classes which rose up in times of urban and economic development. But this development struggles to delete the old system, which persisted until the end of 18th century with the arrival of Napoleon. The transition from the Patriarch＇s power to Venice＇s dominion seems to have created two main consequences： by one hand a more bureaucratic and modem structure of the State, by the other hand a consolidation of the old connections between patrons and clients, consequence of the ＂modem＂ feudal system that consolidated its roots in the Late Middle Ages centuries.

档案文献所呈现的清前期在台湾地区设立土司之议

康熙二十二年(1683年)至乾隆九年(1744年),清朝统一台湾地区后的六十余年间,闽台官员先后五次提出仿照施行于西南民族地区的土司制度,在台湾地区“番族社会”设立土司,其中康熙朝两次,雍正朝两次,乾隆朝一次。前三次均为“私议”,第四次为南澳镇总兵许良彬的奏请,虽直达“天听”,但均未纳入清政府决策程序加以讨论。乾隆九年,福建布政使高山奏请在台湾地区“熟番”中设立土司,则经过户部议准、乾隆帝允行,再到闽浙总督马尔泰等提出反对并获乾隆帝支持的反复,前后历时近一年,最终被否决,相关讨论由此画上句号,此后再无人提及在台设立土司之事。本文拟通过档案文献厘清这一历史过程,并从雍正朝西南边疆实施大规模改土归流后土司制度的发展变化,结合同时期川西北“番族社会”设立“流职土司”情形,审视高山奏议所具有的积极意义和特殊历史价值。

新中国初期海南黎族苗族地区提高农业生产力措施研究

海南全岛解放后,党和政府根据黎族苗族地区经济社会文化实际,制定了一系列以经济-文化为主的政策措施,促进了海南黎族苗族地区由初期农耕社会-狩猎采集社会向农耕社会的转化,使得其农业生产力水平迅速提高、基础设施迅速改进、教育文化水平迅速提升、人民生活水平显著改善,迅速地拉近了与其他地区经济社会发展水平的距离,并为今后进一步发展奠定了基础。实践证明,这些政策措施,既符合农业社会的发展规律,又充分联系了黎族苗族地区的实际,因而在当时取得了良好的政策效益,其亦给当今推动海南黎族苗族地区的发展提供了很好的借鉴。

麦积山早期洞窟年代与“大凉州石窟”

以第74、78窟为代表的麦积山早期洞窟年代上限可以到十六国晚期,下限在北魏洛阳时代之前。这些早期洞窟与河西石窟连为一体,可统称为“大凉州石窟”,其来源近为新疆,远则中亚乃至印度。“大凉州石窟”并无鲜明统一特征,而以各地各具特色为主,其形成背景在于各地对东来佛教艺术的自由吸收和发挥,这与十六国时期的历史特性相符。与以往认识不同,本文认为麦积山早期洞窟影响了云冈石窟。包括麦积山早期洞窟在内的“大凉州石窟”曾影响到云冈,但不限于云冈,这个认识对于理解东部地区石窟具有重要的意义。

从儒家经典到课本选文:清末民初读经科向国文科的转化与融入

民国初年读经被取消后又被反复提倡,但清末的读经科部分转化、融入了国文科并影响了国文科的发展:国文科课程目标中的“德”由读经科转入,教材中部分课文是对读经科中的整本儒家经典的节选,教学中的诵读法也来自读经科。转化的发生及其成功,主要原因是:读经科改变了形式,顺应了现代教育(国文)的变化,教育目的由培养臣民转为培养公民,教育形式由私塾中的单个点拨到学堂中的班级授课,国文教材形态由专书变为选文,考试文体由八股变为古文。
