Based on the theories of the diamond model, resource endowment, and the value chain, this research establishes a hierarchical model of evaluation indicators of the coal industry′s international competitiveness from both macro and micro perspectives.The whole evaluation system consists of two second-order indicators, eleven third-order indicators, and thirty-one fourth-order indicators.The indicators at the macro level cover the following five aspects related to the coal industry:the production technology level of the industry, the resource factor, the market factor, the industry′s size, and auxiliary industries.The indicators at the micro level compose the follow-ing six aspects related to a coal company:the production technology level of a company, the operational perform-ance, the ability of marketing, the ability of R&D and innovation, the resource endowment, and the degree of internationalization.By the AHP method, this research constructs comparision matrices of evaluation indicators, calculates the vector weights of all the indicators, and checks the consistency of each expert′s evaluation judge-ment.In addition, this research analyzes the characteristics and natures of the evaluation indicators.
Human behavior is both a result of human development in a certain social environment and a reflection of his psychological state.With text analysis and Maslow′s Hierarchy of Needs and Theory of Motivation,this paper explores Prospero′s psychological motivations and needs in his series of acts in The Tempest.From Prospero′s psychological motivations,we can generalize the basic psychological needs of a general man when he understands the universe,the society and himself in different conditions.Human′s action is restricted by his psychological state and cognitive development;His action will improve his cognitive development,which is a periodical and spiral development process.
In Hemingway′s works the indispensable is the deep imprint of his life.A Moveable Feast records Hemingway′s youthful days spent in Paris,his multiple beginnings in life,his perseverance,aggression and progress as well as his abjection and success.This novel is flooded with Hemingway′s nostalgia and affection for Paris which can be easily and keenly observed.The Sun Also Rises is a semi-autobiographic novel,the theme of which is imbued with the base color of Paris life,with the prototypes of heroes and heroines being the writer′s acquaintances in Paris,the scene being Paris scene the writer used to live in,while the plots and the writer′s personal experiences are intertextual.These two works intrinsically and extrinsically reflect Hemingway′s predestined affection for Paris.To do comprehensive research on Hemingway′s works,it′s advisable to carry out research in combination with Hemingway′s life experiences.
Using the method of content analysis,we analyze 2730 research papers in four psychological journals from 1985 to 2014.The results show that students are the main objects and the main research topics include cognitive development,learning psychology,social development,personality traits,em-ployment and occupation.Experimental method and measurement method in the study of psychology holds an absolute advantage.The results also show that there are some differences among different times and different journals.
A transmitted information analysis on distinctive phonetic features was carried out in the current study,based on the data collected from an experiment of Chinese listeners′perception of English consonants in noise conditions.The results showed that the transmitted information on features such as place,manner,voicing and sibilant were all different between Chinese English learners and native English listeners,indicating different strategies of using these features in perceptual tasks in noise between the two listener groups.The native language influence on Chinese learners′English consonant perception was also discussed,and this paper suggests that,to improve Chinese learners′perceptual performance in adverse conditions,more explicit instructions on the key distinctive features between English phoneme categories should be given during the teaching process.
The Great Beauty of the whole cosmos consists in simplicity,which is regarded as the concentrated expression of Wang Bi's naturalism inclination.The naturalism of Wang Bi's metaphysics inherits and develops the thought ofbeauty exists in nature,which is put forward by Lao Zi and Zhuang zi.This new naturalism is based on the proposition ofnoumenon based on nothingness,and it affects Wei-Jin aesthetics widely from three aspects:the beauty of personality,the beauty of nature,the beauty of arts.
The Holy Bible is not only a classical work that rules the spiritual world of the West,but al-so suffices to be both a literary work of high aesthetic properties and a philosophical work that reflects the thought patterns and value orientations of Westerners.For centuries,the Bible has been exerting influences,tangibly or intangibly,upon the literature,language and daily lives of the people in the West.In the current context of globalization in politics,economy and culture,it is also of great signif-icance to acquire a good knowledge of the Bible so as to promote international communication.Moreo-ver,a careful exploration into the stylistic features and translation principles of the Bible might con-tribute to the birth of high quality Chinese Bibles,which,as a result,will definitely help to bridge the people of different faiths within our country and also better Chinese people′s understanding of the Western world,ensuring the success of the Sino Western dialogues.
Transliteration has been discussed from semiotics,referents and cultures.An idea has been presented that transliteration can only be taken as an alternative remedy to deal with the asymmetrical denominating words,and in application of transliteration method,the changes of intra-lingual semi-otic system and the differences in inter-lingual semiotics should be concerned,the referent function be highlighted,and national culture be maintained and showed.Therefore,the principles,strategies and methods of transliteration should be flexibly applied to achieve the effective communication and cultural exchange.
The thermodynamics analysis is made of mass and heat transfer processes in the LiCl liquid dehumidi -fier .According to the dehumidifier structure and the flow patterns of liquid and air , the heat and mass exchange physical and mathematical model of the dehumidifier is set up .The effect of the air and liquid inlet parameters on the related indices is calculated through MATLAB simulation .The influence of dehumidifier′s entrance pa-rameter influence on the evaluation indices is obtained .Simulation shows that desiccant liquid inlet concentra-tion, temperature, mass flow rate and inlet air mass flow rate have a significant influence on the performance of dehumidifier;the relationship between moisture resistance and dehumidification performance of liquid desiccant system is also verified , providing a reference for further research .
At present the utilitarianism and positioning confusion in running of journals dries up contri-butions and deteriorates the quality of the university journals.The external environmental factors in-clude reverse tool effect and utilization of digital network technology ,the utilitarian academic evalua-tion system and value orientation of the system while the main internal factors are:authors lack the rigorous academic spirit,editors fail to keep pace with the times in their comprehensive qualities and roles conversion,review experts are not strict and university journals have few readers with little feed-back information.To resolve the quality dilemma of university journals and promote their quality ,we should strengthen the subject security and the coordinated development of the four groups,promote the adjustment of its own,optimize the survival environment and improve material,institutional and spiritual environment.
Under the cloud manufacturing environment,cloud services be influenced by many uncer-tainties when they combine with each other dynamically.Under the uncertain environment,service composition with a better flexibility can execute users′tasks much better.In order to get the evalua-tion results of flexibility of the cloud service composition,we need a valid evaluation method of flexi-bility of the cloud service composition.Based on the analysis of multi-flexibility of the cloud service composition,an evaluation method covering many types of attributes of flexibility of the cloud service composition is suggested,which provides decision theories and tools for related companies to construct and use the cloud manufacturing platform.
This paper redefines the acquisition criterion and divides DCs into 14 sub-structures accord-ing to the previous study of Xiqiang Xiao(2009).Based on more than 700,000 words corpus of written materials by CFL learners of Thailand,Vietnam and Laos,it points out that the process of acquisition sequence of DCs turns out to be a general shape.The three patterns of DCs are U shape,non-linear and marked,which are “V+ simple DC + location object”,“V+ location objects + lai/qu”and “V+ simple DC (extended meaning)”,and the sentence pattern “V+simple DCs(extending meaning)+non-location objects”which has high utilization is un-marked,the acquisition of unmarked sentence tends to be stable and overused.L1 can still be an important factor for our understanding of the per-ception of grammatical items,which affects its acquisition order and learning speed.Based on the cor-pus of interlanguage and language composition,the true typological characteristics of Chinese DCs are likely to be found.
