Quantitative Case Study

<p>Achieving a near-native speaker’s pronunciation is so essential for EFL learners. However, many factors contribute to the challenges faced by EFL learners, mainly due to the difference in the sound system of English Language and that of their first language. For this reason, Arab learners of English Language may mispronounce some English sounds. This paper analyzed one of the few problematic sounds to the Arab Yemeni EFL learners - the pronunciation of the English voiceless postalveolar affricate /ʧ/. The study which has a quantitative case study design uses four Yemeni EFL postgraduate students as its participants. The participants’ pronunciations of /tʃ/ sound in the initial, middle and final word-positions were analyzed using Praat phonetic software. The findings of the study showed that Yemeni EFL learners have difficulties in producing the /tʃ/ sound, especially in the initial and final positions, and deaffrication of /tʃ/  occurred in the  pronunciation of the four participants. The current study is expected to be of value, particularly for EFL learners, teachers, as well as material writers.</p><p> </p>

Declining Attendance

The movie substitutes such as home cinema, video on demand (VOD), and plasma televisions leaded to a declining attendance of patrons to movie theatres, which urged the invention of IMAX theatre to call movie lovers back to cinemas. Many cinemas plan to renovate their regular digital theatre auditoriums into IMAX theatre auditoriums, but there lack of study for built environmental variations between regular and IMAX theatres. Through the combination of a questionnaire survey and a case study on a leading cinema company in Malaysia, the Tanjong Golden Village Cinemas (TGV), this paper aims to identify the structural and architectural differences between regular digital theatre auditorium and IMAX theatre auditorium in the perspectives of acoustic and visual experiences. The most significant factor influencing the satisfaction of visualization in IMAX is “immersive of picture” followed by “sharpness of colour” and “feels as part of the picture”. The most significant indicators for audio experience in IMAX is “direction of object”, which enable an audience to trace the direction and position of an object on the screen without looking at it. The built environmental variations between regular and IMAX theatres in terms of screen, camera and projection methods, seating, architectural layout, wall design, and sound system arrangement were thoroughly compared in the case study.
