What Is English As A Lingua Franca?

What Is incline As A natural language Franca?Over the last few decades, with global spread and wont of face, any(prenominal) searchers direct shown an increased interest in side of meat as a Lingua Franca. The issue of pixy has eventually be rise an important focus of research in applied Linguistics. McKay (2003) emphasizes that local context and learners contracts should play an important role in the teaching of face. Kirkpatrick (2007) claims that we, as side of meat verbiage instructors, should reconsider which prototype of side of meat should be adopted for the language classroom in countries where English is utilise mainly for international communication.This paper seeks to the following things. Firstly, the paper go forth explore what is meant by English as a Lingua Franca ( extremely low frequency) and followed by the watchword the importance of relevant issues, such as choosing the right teaching moulding, cross-cultural intelligibility and strategies, t rying on and open-minded attitudes towards varied English varieties. Secondly, with respect to Chinese context, the creator will discuss the choice of appropriate teaching exercises. As an English language teacher in chinaware, the author claims that the choosing of teaching models should be base on the local context and learners needs. Finally, the author will discuss the development of chinaware English in Chinese context.2. What is English as a Lingua Franca?2.1 The Spread of EnglishNowadays, at that place is no doubt that English is an international Language. It is widely utilise as a communication medium in the fields of politics, economicals, culture, technology etc. Crystal (2003) points out that the number of non- aboriginal speakers (NNSs) of English is far to a greater extent than inherent speakers (NSs) and claims that approximately only unrivaled of every four users of English in the k forthwithledge base is an English native speaker.2.2 World EnglishesWith the spread of English in the world, there be now many varieties. Jenkins (2004) refers to these as world Englishes. In other words, English no longer has one single base of authority, prestige and normativity (Mesthrie Bhatt, 2008).The three circles model proposed by Kachru (1992) has been very influential and gives us a dandy actualiseing of the spread of English and world Englishes. These three circles, based on geography and history, ac bonkledge the Inner flock, the Outer Circle and the Expanding Circle. The Inner Circle comprises the countries in which mint speak English as a native language (erythema nodosum leprosum), known as Norm-providing, such as USA, UK, Australia, Canada and New Zealand. The Outer Circle includes the countries where English is spoken as a second Language (ESL), most of which used to be the colonies of UK, US, and regarded as Norm- ontogeny. Jenkins (2009) points out that one of the main characteristics of the Outer Circle countries is that the v ariations of English in ESL have become institutionalised and ar developing their own standards. The Expanding Circle gist EFL countries, such as mainland china, Japan, Korea and Thailand, known as norm-dependent. The main reason for defining the Expanding Circle is that English has no official status and can be seen as dependent on the norms of the inner circle countries (Jenkins, 2009).2.3 English as a Lingua FrancaHowever, language is always developing and changing. With the spread of English, Kachrus three circles model (Kachru, 1992 )is criticized by virtually scholars (Jenkins, 2005 Seidhofer, 2004) because it pays more attention to the interaction betwixt native and non native speaker, and has not recognized that one of the most important functions of world-wide English today is to yield a lingua franca amongst all three circles. In particular, the interaction takes place within the Expanding Circle (Mollin, 2006). Therefore the term ELF is proposed beneath this acc ompanimentIn the first place, it was widely accepted that ELF does not include native speakers. House (1999) defines ELF interactions between members of two or more different linguacultures in English, for none of whom English is the mother tongue. In other words, from Houses point of view, ELF meat English is spoken by speakers whose first language is not English. Jenkins, however, claims that the term English as a Lingua Franca (ELF) refers to the English that is used as a contact language among speakers who come from different first language and cultural footing (Jenkins, 2005). In other words, despite the fact that native speakers be not like non-native speakers which represent a large percentage of the heart and soul of the worlds ELF users, they are still included in ELF, But their interactions are not collected in Jenkins ELF data, and when they take part in ELF interactions, they do not represent a linguistics reference point (Jenkins, 2007).ELF is characterized by the f ollowing (1) ELF is used in different contexts in which speakers have different L1 and cultural background, provided they need it as a tool to achieve their communication goal. During this communication process, they need to be open-minded, tolerate and book each other (Politeness, schema theory and so on). (2) ELF is different from EFL which the main purpose is to communicate with native speakers and the interaction needs to adhere to ENL linguacultural norms. (3) Linguistically, ELF involves innovations, performativity and creativity that differ from ENL (Seidlhofer, 2011). When Speakers negotiate meaning with each other in English, they may change the ENL norms. For example Use of tertiary person singular zero. She/he go to school. More details please see the appendix one (Jenkins, 2009).Obviously, the term ELF well represents English as it is used today. In addition, the ownership of English does not only belong to native-speakers, it belongs to all who communicate with each other in English (Nelson, 2011). With the global use of English, Cross-cultural Intelligibility, accepted communication strategies are needed in ELF interaction, such as accommodation and code switching, the cognisance of noticing the circumstantial communication context. The discussion will be explored in the next session.3. ELF and relevant issues for the classroom3.1 The teaching modelsSeidlhofer (2006) points out that, with global use of English, a problem is raised to shoot the teaching model what English should be taught in a specific context? What norms of English should be adopted? People make different choices based on their needs and context of learning English. Three models are proposed by Kirkpatrick (2007 184-197) exonormative native speaker model, endonormative nativised model, and a lingua Franca approach. Most people in Expanding Circle Countries would like to choose the exonormative native speaker model, because most of them learn the standard British and Americ an English and their respective standard accents, RP(Received Pronunciation) and GA (General American),despite the fact that they know learning English is not only to communicate with native-speakers(Jenkins, 2009). But in fact, the term standard English deals with grammar and vocabulary (dialect) but does not include orthoepy (accent) (Trudgill Hannah, 1982). Shepherd (2000) claims that which model is chosen depending on the learners needs and should use the learner-centred approach. In the meantime, it is very challenging for speakers who are in expanding circle countries to achieve native-like English. On the contrast, it will not motivate the learners and makes them lose confidence in learning it (Seidlhofer, 2011).3.2 Cross-cultural intelligibility and strategiesAs English continues to grow as a lingua Franca, there are a lot of variations of English. How should we achieve the cross-cultural communication? Smith (1976) pointes out the view below 1) There is no need for learne rs to internalize the culture norms of native speakers of the language 2) the ownership of an international language becomes denationalized and 3) the primary goal of learning language is to make learners to communicate their ideas and culture to others. For example, generally speaking, Nelson points out that (2011) we will draw who people are, where he or she comes from by his or her lexical choice or accent forwards we communicate with other person from different background with us. However English is currently used as a Lingua Franca, the goal of communication is to make each other understood.International Intelligibility is getting more and more important and become a concern in recent days, especially sagacity each other in multiple contexts (Nelson, 2011). Therefore developing the students listening and comprehensibility and speaking skills are very crucial in order to understand people and make other people understood who come from different backgrounds with different acce nts. Since the purpose of learning Language is to achieve communication, so how to get the meaning of language through different pronunciation or accents when people speak English is proper a main issue in ELF. Learning linguistic features and knowing different cultures might be helpful to understand different variations. Therefore understanding your speaker linguistically and culturally will lead to successful communicate in a super diversity context, In short, Knowing how, when, and why to say what to whom.Furthermore, in order to achieve the international intelligibility and sound communication, raising the awareness of the strategies of lingua franca communication is becoming more and more important in the interaction. Promoting multi- competence among native and non-native language users (Cook, 2007), the accommodation theory, the schema theory, the speech act theory, cultural information, cross-cultural negotiation and strategies, language technology, cultural awareness and s o on3.3 ELF attitude and identitiesNow English is becoming a Lingua Franca, hence the norms of native speakers countries are not only one standard, in the meantime, non-native speaker countries have got the ownership of English. So not only non-native speakers need to accept the native-speaker norms, they have got their own particular norms. At the same time, Jenkins (2007, 2009) claims that native speakers should accept non-native speakers norms .Because in the current situation the expanding circle is potentially rather different from typical situations in which powerful NS groups impose their linguistic norms on little powerful, often minority, NNS groups. In particular, many groups of English speakers in parts of Europe, Latin America, and East Asia (especially China) are both economically powerful and numerically large, and this may in conclusion prove to be decisive in the fight for the recognition of ELF, in turn, it may affect the ELF identity landscape in ways that are at present only dimly discernible (Jenkins, 2009 Seidlhofer, 2011).Widdowson (1993 385) claims that it is a matter of considerable pride and satisfaction for native speakers of English that their language is the international means of communication. However, it is very hard for native or even non-native speakers to accept the worlds Lingua Franca which has its own lexicogrammar and accent characterises and should have its own right to develop its own Lingua Franca forms. For instance China English, Japan English. Even these features did not cause intelligibility problems and can achieve the goal of communication (Jenkins, 2004). For more details, please see the appendance one.Identity is becoming an interesting issue in English language use nowadays. Recent literature (B. Kachru and Nelson.2001 De Kadt, 2004) point out that the use of English plays an important role in showing groups and individuals identities. Because non-native speakers use English with their own characters show the ir own identities. Especially people use English to communicate with people who came from different background, For example, the interaction between a Chinese English and Korea English speaker, and they may be identified by each others pronunciation and accent. In most of cases, English language teachers and learners craving native-like English identity in Expanding Countries, Especially for non-native English teachers. In their mind, native-like English accents are helpful for them achieve the success in the career development.4. Rethinking ELF in ChinaKirkpatrick (2006) points out that context should be considered before making the decision to choose the teaching model, and the context includes learners needs and the relative possibility of adopting nativized model. Next, the role of English based on Chinese context and learners needs are discussed in more detail, then the teaching model in China is described, and the development of China English is explored.English in China Nowa daysWith the spread of English, English is seen as extremely important and strongly promoted in China. The motivation for learning English for Chinese learners are discussed in more details based on Chinese context, and the uses of English in China is always changing over time.With economic reform and open door policy of China in 1979, and the motivation of learning English is to acquisition Western knowledge (Kachru, 1992 165) and international understanding. English is a compulsory subject in primary, secondary and universities in China, they need to pass the examinations. Students in secondary need to pass the National Examination to access to university, students in the majority of Universities need to pass CET band 4 to get the degree. Some students who want to study abroad need to pass IELTS and TOEFL. Here, the role of English is as a medium to access to science, technology, political, business, culture information around the world.However, nowadays more and more teachers and learners notice that learning English is to international communication. Especially, since China entered WTO in 2001 and held 2008 Olympic Games, these make China get involved in globalization. For example, many companies in USA and some European countries found that they can cut the cost and make more profit if they send their jobs in China, it is well known as outsourcing. People in China who want to work in these companies need to have a last proficiency of English. In addition, with the development of China, more and more people study abroad, travel and immigrate around the world, and they are uncovered to English with different accents. They not only need to communicate with people in the inner Circle countries.America and UK, but as well need to interact with people in some Outer Circle and the Expanding Circle(Singapore, India, Malaysia, Japan and Korea).Finally, with China emerging as an economic superpower, Chinese government found that China not only needs to learn the knowledge from the world, but also need to let the world know about China, Confucius Institutes have founded all over the world since 2004, which provide opportunities for people to know Chinese Language and culture. For mandarin Chinese teachers, they need to translate Chinese Language and culture into English. However, sometimes it is very hard to find the word in English vocabulary to express Chinese language and culture. Therefore, direct translations from Chinese into English take place(Kirkpatrick,2007), such as taichi, kung fu, fengshui, adjure rice bowl, one country, two systems, open-door policy.4.2 Teaching models in ChinaAs mentioned earlier, Kirkpatrick (2007) points out that there are three potential models which can be used in outer and expanding circle countries, and they are an exonormative native speaker model, endonormative nativised model and a lingua franca approach. China is one of such expanding countries, and the exonormative native speaker model has been ac cepted and promoted as the standard pedagogic model for English language teaching in China. However, there are still a lot of changes during the gunpoint of development of English in China. In the outgoing, only native-speaker varieties and norms are used and other varieties of English are ignored in China. British English is regarded as standard English in the beginning with the economic development of America, American English dominated in the ELT of China, mixed with a little British English in the last two decades, with the economic development of China, more and more foreigners from different countries in the world go to China to do business, study and travelling, and some Chinese people are exposed to different varieties of English and they found it hard to communicate with foreigners with different accents. This raises their awareness of the importance of other varieties of English. Therefore, nowadays, other varieties of English are taken into account in English curriculum . Including Canada English, China English, India English, Nigeria English, Japan English, and so on. English teaching materials have reflected these changes and tend to incorporate the principle of English as a Lingua Franca in terms of cultural knowledge. In the English teaching materials, not only the culture of native speaking-English countries is introduced, but also the culture from the inner and expending counties is presented inside.Kirkpatrick (2006) points out the advantages of adopting the exonormative native speaker model in the Outer and Expending Circle countries. Firstly, this model has been codified in the lexicon and grammar books Secondly, this model is regards as standard varieties of English thirdly, this model has got power. Fourthly, this model has got historical authority (ibid 72). The above reasons also can explain why the learners in China want to learn American and British English, and why they regard American and British English as Standard English. Howev er, with the global development of English, other varieties of English have already started to be drawn attention in the field of ELT in China.Kirkpatrick and Xu(2002) points out that the reason for learning English should be clarified before choosing the right English teaching model, if learning English is to communicate with native speakers, then the exonormative native speaker model will serve a good role, however, in fact, In China, the purpose of learning English is not only to communicate well with native speakers, but also communicate with non-native speakers, and the number of non-native speakers has already exceeded the number of native speakers, in the meantime, the number of non-native speakers are still growing at the fast speed. Therefore, they argue and suggest that the development of China English with Chinese characteristics may be an inevitable result (ibid 277).4.3 China EnglishThe concept of China English has been attracting growing attention from scholars over th e past 20 eld (Du and Jiang, 2001 Kirkpatrick and Xu, 2002 Hu, 2004 Bolton, 2003,). This concept is different from the older terms Chinese English and Chinglish, because Chinese English and Chinglish are ungrammatical or nonsensical English and are not standard variety. Chinese English refers to a variety of English used by Chinese learners and bears feeling of L1 interference (Kirkpatrick and Xu, 2002).while Chinglish refers to the combination of English and Chinese in ones reprobate. China English was first defined by Ge in 1980 (Du and Jiang, 2001), and it is described as it is understood as a standard variety and used by Chinese People in China, and it has Chinese characteristics in lexis, sentence structure and discourse and reflects Chinese culture norms (Li, 1993Du and Jiang, 2001).Undoubtedly, English is a lingua Franca now and English should be learnt with the culture of the target language to a certain extent in order to learn English language. In the meantime, in the C hinese context, China English should be developed to make it part of the main English. For example, during the period of learning Mandarin Chinese, many students are interested in Chinese culture, i.e. Acupuncture and moxibustion treatment, traditional wedding, traditional Chinese musical instruments, the ancient Chinese works, Chinese food etc. But it is hard to find English words to describe these special things with respect to Chinese knowledge and culture. This is a big problem and challenge for Chinese people to communicate with foreigners in English. The emergence of China English contributes to the development and enrichment of English and spread the Chinese culture around the world, so it is necessary to develop China English with Chinese characteristics in lexis, sentence structure and discourse and become one part of the worlds Lingua Franca. and China English needed to be codified to appear in dictionaries and reference books, of course, there is a long way to go before C hina English become one standard variety, this not only needs official support, but also needs to change peoples attitudes towards China English, and further research needs to be done to investigate China English with respect to phonology, lexis, discourse and culture. Kachru (1992) emphasizes that full-grown the rights to develop the variety of norms would not lead to a lack of intelligibility among varieties of English.5. ConclusionIn this paper, this author has discussed the understanding of ELF from narrow and wide view. Secondly, this paper has explored the implications of ELF for classroom issues Choosing the teaching model should be based on students context and needs In order to achieve the Cross-cultural Intelligibility, we should raise the students awareness of effective communication strategies as long as non-native speakers features such as lexicogrammar and pronunciation do not cause Intelligibility problems and can achieve the goal of communication, we should be open- minded and accommodate each other (Cogo Dewey, 2006 Dewey, 2007). More importantly, some people would like to keep their own identity when communicating with each other in English. Finally, this author focused on the discussion of teaching model in China based on Chinese context, and then the author discussed China English and advocated China should develop China English along with learning native-speaking culture and this may be next big trend on teaching English in China.Nanoparticles Applications and Impact on scienceNanoparticles Applications and Impact on ScienceNanoparticles (NPs) functionalised with cores composed of inorganic and organic materials like noble element, magnetic metals, their alloys and oxides, and semiconductors are ehaustively studied and have colossal potential for application in various areas. The spectrum of applications are endless and embraces nano-biomedicine, nanoprobes for diagnostics to treatment of diseases, nanobots for early detection of neoplas tic cell, nano medicine delivery systems, Nanosuspension, SPION, nanolithography for nanoelectronics industry, electro chemic sensing supported by gold nanoparticles impregnated halloysite nanotube composites and latent fingerprint detection for forensic investigations are to call a few. The effects of nanoparticles ought to be foreseeable and temperlable, and bear the specified result with minimum cytotoxicity. These criteria are met by the careful craft of the core shell, allowing stabilization, specific targeting and recognition of biochemical species. This review is focused on the synthetic thinking and functionalisation of a wide range of nanoparticles for various applications.Keywords nanoparticles, SPION, nanobots, halloysite, nanodrug delivery system forensic investigators, nanoelectronics.1.INTRODUCTIONThe incredible accomplishments created within the discipline of material science and nanotechnologies over the past decade have had a significant encounter on the biolog ic, material, and, chemical sciences. Recent developments in the life sciences rely profoundly on the supply of current state of the art experimental tools and devices that modify and manipulates biomolecules and avail the study of complex biological processes at the molecular and cellular levels. Significant progress created inside the synthesis of fluorescent semiconductor Nanocrystals (NCs), further brought up as quantum dots (QDs), aboard an extra robust understanding of their nonlinear photo physical properties and then the event of biocompatible rise up chemistries for their solubilization, have provided new imaging probes with monumental potential for scientists in the biological domain 1-3. The distinctive optical properties of these semiconductor Nanocrystals make them exceptional fluorescent biological markers.The leptons in QDs are confined in all three dimensions, resulting in a powerful size dependency of optical behavior like absorption, contagion and, consequently , emissive energies 4. The radiative recombination of the charge carriers that ends in fluorescence emission once the lepton falls into the valence band is greatly inflated by quantum confinement, compared with their bulk semiconductor 5-8. Thus, by reducing the dimensions of certain semiconductors to a couple of nanometers, new fluorescent probes may be obtained entirely different from their bulk counterpart. Additionally, by varying the nanometric size a greater control over the fluorescent properties of these probes like their emission wavelength can also be achieved to utilise its complete spectral potential 1.Nanoparticles are constructs that possess distinctive physical and chemical properties associated to their size domain of 1100 nm or a minimum of one dimension need to fall in the government of 1-100 nm. NPs consist of a spread of materials as metallic nanoparticles of noble metals of Gold / Aurum (Au) 9, Silver/ argentous (Ag) 10,11, atomic number 46 (Pd) 12, atomic numb er 78 (Pt) 13,magnetic compounds (viz. Co 14, Fe3O4 15,16, FePt 12, CoFe2O4 17, CoPt 18), semiconductors (viz. CdS 19, CdSe 20, InGaAsP 21, GaAs 22, GaAsP 23, ZnS 24, TiO2 25, Lead Sulphide (PbS) 26, Indium Phosphide (InP) 26, Silicon (Si) 27), core shell (viz. CdS/CdSe 28, CdSe/ZnS 29, CdS/ZnS 30, CdSe/AgS 31, HgS/CdS 32, PbS/CdS 33, 34, CdS/HgS 35, ZnS/CdSe 36, ZnSe/CdSe 37) and different nanocomposites nanomaterials (viz. Co/WC and Fe/TiC). Therefore, as for the NPs to be useful in biomedicine, they need to satisfy certain criteria. For in-vitro applications like fluorescent staining of proteins and TEM imaging, NPs ought to trounce the traditional agents whereas having minimal toxicity. In-vivo, NPs got to be compelled to avoid non-specific interactions with plasma proteins (opsonisation) and either evade or allow uptake by the reticulo endothelial System (RES) hoping on the applying, to attain their meant target efficiently. They need to in addition maintain homogeneity and sta bility under physiological conditions, ideally within a good spectrum of pH. NPs carrying a payload, like drug molecules or de-oxyribonucleic acid (DNA) for cistron treatment ought to avoid premature release, at the same time should precisely deliver the load to the desired site. To accomplish these phenomenon Surface Chemistry of the NPs should be well known and modified accordingly for specific interactions with biological moieties of interest.Nanoparticles-based drug delivery system provides many blessings, like enhancing targeted drug delivery, resulting in drug-therapeutic efficiency, reduction in dosage quantity, and pharmacological characteristics. Moreover, nanoparticles to boot improve the solubility of sparingly soluble drugs,dramatically alter pharmacokinetics mechanism, enhances drug half-life by reducing immunogenicity, increases specificity towards the target cell or tissue (therefore reducing facet effects),improve bioavailability, diminishing drug metabolism, provid ing controllable release of therapeutic compounds and in addition the delivery of two or more drugs at an equivalent time for combination medical maintenance 38,39.In the field of qualitative analysis, UV, FTIR-ATR 5 shows a stimulating spectral improvement in peaks of sample analytes rendering a quicker analysis even from a trace evidences. DC magnetron sputtering of nanoparticles on noble metals like Gold and Silver on samples of forensic evidences viz blood, semen, spittle and latent fingerprints shows an enhanced and improved spectrum under invisible light, FTIR-ATR and UV/VIS spectrum measurement devices. The spectral improvement is a result of Quantum confinement effect 40 of nanoparticles.This article is split into three sections of Pharmaceutical applications, Engineering and Technology and additionally the foremost expected field of forensic investigation. The article in addition presents current and futuristic market potential for Nanomedicine and numerous different nano electronic devices and its impetus impact on humanity.2. Pharmaceutical Applications of nanoparticlesThe potential application of nanoparticles is in the field of Nanomedicine. Nanomedicine as the name indicates is the branch of nanotechnology that deals with medical application of engineered nanotechnology. Though, the definition of nanotechnology and Nanomedicine continues to be an open tough field, contention and brain storming among academicians and industrialists we might wish to advocate wide accepted definitions by variety of the reputed regulatory authorities, research institutes and government agencies across the world.United States nutriment and Drug Administration (USFDA) outline nanotechnology asTechnology which allows scientists to create, explores, envision, and manipulate materials scaled in nanometers (10-9 m). Such engineered materials can have an entirely different set of properties (physical, chemical and biological) that dissent from those of their larger count erparts 41.National Institute of health in its National Institutes of Health Roadmap for Medical research in Nanomedicine programme defines Nanomedicine asAn offshoot of nanotechnology, which refers to passing specific medical interventions at the molecular scale for curing disease or repairing damaged tissues, such as bone, muscle, or nerve 42.European Science Foundations (ESF) Forward Look Nanomedicine program has given comprehensive definition of Nanomedicine asNanomedicine uses a set of nano-sized tools for the diagnosing, preventing and treating of disease and to gain insight and in-depth understanding of some of the complex underlying patho-physiology of disease. The ultimate goal is to improve the quality-of-life 43.Since last two decades Nanotechnology has evolved as the most promising engineering technology in impudent drug delivery systems and in diagnostic techniques. The very fact may be determined by the number of promising Nanomedicine candidates approved by complet ely different regulatory authorities across the world for these applications. The Nanomedicine here represents umbrella term that covers the molecules at a lower place the scale of one guanine nm in at least one dimension and has potential applications among the subsequent fieldsAdvanced and targeted drug deliveryReal time imaging and diagnosisRegenerative drugs.2.1Nanoparticles for site dependent and targeted Drug DeliveryThe size confluence of nanoparticles with proteins is the major reason that nanoparticles are widely used in therapeutic applications 63. Their huge surface area provides a binding site for displaying surface functional groups like ligand. Moreover, they possess a speedy absorption and unleash behavior provided by high skills of their diffusion and surface modification. Nanoparticles in its synthesized form are rarely used in biomedical application on account of its inherent properties viz cytotoxicity and high surface charge. Their high toxicity destroys healthy cells and enormous surface charge renders them highly unstable prohibiting its medical application. Therefore, the particle size and surface characteristics of nanoparticles are in general tailored or controlled to suite user needs and medical interests. Some distinguished examples of surface modification of nanoparticles are covalent binding between surface and functional molecules or polymers, electrochemical sensors added gold NPs and halloysite nanocomposites 44 and layer-by-layer (L-b-L) self assembly. Whereas organic, inorganic or organic/inorganic hybrid materials are used for the fabrication of nanoparticles, polymeric nanoparticles have in
