Nutrition and Education in an Urbanizing Nation
Child malnutrition is a growing public health issue in Nepal, particularly in urban areas. Not eating enough, or not eating enough of healthy foods, can have life-long implications on development and cognitive ability. Because of its relevance to development within the country, many donor organizations and non-governmental organizations are working to promote child nutrition education programs. The purpose of this research is to investigate the implementation and structure of urban child nutrition educational programs involving treatment and prevention in Kathmandu, Nepal. Through qualitative interviews and field observations with three primary organizations, this research analyzes the patterns and disconnects between various efforts being made to design and implement educational curriculums
Large Eddy Simulation of the Pulsating, Non-Reacting Flow in Combustion Chambers
In the present work a numerical investigation of the pulsating, non-reacting flow in a combustion chamber, and a coupled system of burner plenum and combustion chamber is presented. The results are compared with an analytical model and experimental data. The numerical simulations provide the damping ratio, an important input, for the analytical model, which was developed to predict the stability limits of technical combustion systems
Becoming IELTS Examiners: Demystifying Native-Speakerism in the Area of English Language Testing
The field of English language teaching (ELT) has long been a fertile soil for native-speakerism where the native English teachers (NESTs) enjoy the privilege to be crowned as the ideal teachers of the language. Â Such belief is ingrained in all aspects of ELT including English language testing such as in International English language Testing System (IELTS), where the presence of non-native English examiners is extremely rare. Departing from this phenomenon, this study, conducted as a narrative case study, embarked to counter such claim by looking into the professional credentials and experiences of three non-native English teachers (NNESTs) who, against all odds, become official IELTS examiners in Indonesia. The data of the study were gathered through interviews and analyzed using thematic analysis. The findings show that the participants develop native-like level of fluency as the result of their investment in developing English skills through engaging in English mediated communication, interactions and learning in private English language institutions (PELIs). Moreover, their success is also attributed to their international teaching certificates which opened doors for them to compete with NESTs. Thus, this study seeks to inspire NNESTs to continuously develop their teaching credentials and to boost their confidence as legitimate teachers of English.Pengajaran bahasa Inggris telah lama menjadi lahan subur bagi ideology native-speakerism; penutur asli Bahasa Inggris menikmati hak istimewa sebagai guru bahasa Inggris yang ideal. Keyakinan tersebut telah mendarah daging dalam semua aspek ELT termasuk tes bahasa Inggris seperti di International English Language Testing System (IELTS), di mana kehadiran penguji bahasa Inggris yang bukan penutur asli Bahasa Inggris masih sangat jarang ditemui. Karena fenomena tersebut, penelitian ini, dilakukan sebagai studi kasus naratif, bermaksud untuk mempertanyakan klaim tersebut dengan melihat kredensial profesional dan pengalaman tiga guru bahasa Inggris bukan penutur asli yang, dengan segala perjuangannya dalam melawan segala rintangan, untuk menjadi penguji IELTS resmi di Indonesia. Data penelitian dikumpulkan melalui wawancara dan dianalisisa menggunakan analisis tematik. Temuan menunjukkan bahwa para peserta penelitian mengembangkan tingkat kefasihan seperti penutur asli sebagai hasil dari investasi mereka dalam mengembangkan keterampilan bahasa Inggris melalui penggunaan Bahasa Inggris dalam komunikasi, interaksi social dan pembelajaran di lembaga bahasa Inggris. Selain itu, keberhasilan mereka juga tidak terlepas dari sertifikat pengajaran internasional yang mereka dapatkan yang telah memberikan kesempatan bagi mereka untuk bersaing dengan NEST. Oleh karena itu, penelitian ini bertujuan untuk menginspirasi NNEST untuk terus mengembangkan kredensial mengajar mereka dan meningkatkan kepercayaan diri mereka sebagai guru bahasa Inggris yang sah
A Narrative inquiry into private English language institution non-NES teachers’ identities in Indonesia:Journeys of becoming English teachers
Akusztikai célú anyagok dinamikai tulajdonságainak kutatása = Dynamic properties of materials for sound insulation in buildings
A tĂ©ma közĂ©ppontjában az akusztikai cĂ©lĂş anyagok dinamikai tulajdonságának, illetve viselkedĂ©sĂ©nek kutatása állt. A munkának alapvetĹ‘en három cĂ©lja volt. Az egyik cĂ©l az volt, hogy Ăşj ismereteket szerezzĂĽnk az akusztikai cĂ©lĂş viszkoelasztikus anyagok dinamikai tulajdonságainak frekvenciafĂĽggĂ©sĂ©rĹ‘l, kĂĽlönös tekintettel a nagyfrekvenciás tartományra. Ennek eredmĂ©nyekĂ©nt arra az Ăşj megállapĂtásra jutottunk, hogy a viszkoelasztikus anyagok komplex rugalmassági modulusa nagyfrekvencián nem korlátos növekedĂ©st is mutathat. Igazoltuk, hogy ez a nagyfrekvenciás viselkedĂ©s összhangban van az általános Ă©rvĂ©nyű Kramers-Krönig diszperziĂłs összefĂĽggĂ©sekkel. A kutatás másik cĂ©ljának megfelelĹ‘en kidolgoztunk egy Ăşj anyagmodellt, amely elsĹ‘sorban a kis vesztesĂ©gű anyagok esetĂ©ben alkalmas a dinamikai tulajdonságok frekvenciafĂĽggĂ©sĂ©nek matematikai leĂrására. A kutatás harmadik cĂ©lja a viszkoelasztikus anyagok komplex Poisson száma vesztesĂ©gi rĂ©sze - az Ăş.n. Poisson vesztesĂ©gi tĂ©nyezĹ‘ Ă©rtĂ©kĂ©nek a meghatározása volt. Ennek során igazoltuk, hogy a Poisson vesztesĂ©gi tĂ©nyezĹ‘ az anyag energiaelnyelĹ‘ kĂ©pessĂ©gĂ©n kĂvĂĽl a dinamikai Poisson számtĂłl is fĂĽgg. Ăšj elmĂ©leti összefĂĽggĂ©seket dolgoztunk ki, amelyek lehetĹ‘vĂ© teszik a Poisson vesztesĂ©gi tĂ©nyezĹ‘ meghatározását a nyĂrási vesztesĂ©gi tĂ©nyezĹ‘ Ă©s a dinamikai Poisson szám ismeretĂ©ben. Az összefĂĽggĂ©sek Ă©rvĂ©nyessĂ©gĂ©t kĂsĂ©rleti adatokkal is igazoltuk. Kutatási eredmĂ©nyeinket a szakma rangos, nemzetközi folyĂłirataiban, illetve fĂłrumain közöltĂĽk. | The dynamic elastic and damping properties of solid materials used for sound and vibration control were in focus of this research work. The research project basically had three aims. The first aim was to investigate the frequency dependences of dynamic properties of viscoelastic materials with special respect to the high frequency range. As a result of investigations it has been found that the complex modulus of elasticity of viscoelastic materials may exhibit unbounded increase at high frequencies. It has been proved that the unbounded high frequency behaviour is in agreement with the Kramers-Kronig dispersion relations. The second aim of the project was to search for material models to describe mathematically the dynamic behaviour of materials used for acoustical purposes. A new model has been developed which is able to describe the dynamic behaviour of solid materials experienced over a certain frequency range. The third research aim was to determine the Poisson's loss factor of solid viscoelastic materials. It has been proved that the magnitude of the Poisson?s loss factor is proportional to the damping in viscoelastic material, moreover it is dependent on the dynamic Poisson?s ratio too. New theoretical relationships have been found which enable one to determine the Poisson?s loss factor from knowledge of the shear loss factor and the dynamic Poisson's ratio. The theoretical results have been verified with experimental data
