The Intelligibility of English in Global Contexts: Concepts, Methods, Findings and Implications
Jagdish Kaur 서울대학교 외국어교육연구소 2018 외국어교육연구 Vol.22 No.-
Intelligibility is considered key to successful and effective human communication. The intelligibility of the English used by its non-native speakers is the subject of much research enquiry, and as English continues to strengthen its foothold in international settings as the global lingua franca, the issue of mutual intelligibility has never been of greater importance. The paper begins by examining “intelligibility” as conceptualized by scholars in the fields of World Englishes (WE) and English as a lingua franca (ELF). While WE scholars approach the subject by investigating the international intelligibility of the new varieties of English, particularly to other non-native speakers of the language, ELF researchers seek to uncover how speakers negotiate and co-construct intelligibility in interaction, and the kinds of accommodation strategies employed in the process. Although the underlying assumptions and the methodologies associated with the 2 fields are not always congruent, the findings contribute towards developing a clearer picture of the subject of intelligibility in global communication. The paper ends by considering the pedagogical implications of the findings of intelligibility studies in WE and ELF.

Performance improvements of organic solar cell using dual cathode buffer layers
Sheenam Sachdeva,Jagdish Kaur,Kriti Sharma,S.K. Tripathi 한국물리학회 2018 Current Applied Physics Vol.18 No.12
The present study deals with the effect of dual cathode buffer layer (CBL) on the performance of bilayer of 4,4′- cyclohexylidenebis[N,N-bis(4-methylphenyl)benzenamine] (TAPC) and fullerene (C70)-based organic solar cell (OSC) with low donor concentration. OSC devices with CBLs have been fabricated using thermal vapor deposition technique. We report the use of lithium fluoride (LiF) and molybdenum trioxide (MoO3) as CBLs. The insertion of LiF between C70 and aluminium (Al) electrode enhances the power conversion efficiency (PCE) of device from 1.89% to 2.47% but quenching of photogenerated excitons is observed at interface of C70 and LiF layers. Incorporation of MoO3 between LiF and Al electrode further enhances PCE of device to 3.51%. This has also improved the material quality and device properties, by preventing the formation of gap states and diminishing exciton quenching.

Background: Nasopharyngeal carcinoma (NPC) is endemic in Southern Chinese and Southeast Asian populations. Geographical and ethnic clustering of the cancer is due to genetic, environmental, and lifestyle risk factors. This case-control study aimed to identify or confirm both genetic and non-genetic risk factors for NPC in one of the endemic countries, Malaysia. Materials and Methods: A panel of 768 single-nucleotide polymorphisms (SNPs) previously associated with various cancers and known non-genetic risk factors for NPC were selected and analyzed for their associations with NPC in a case-control study. Results: Statistical analysis identified 40 SNPs associated with NPC risk in our population, including 5 documented previously by genome-wide association studies (GWAS) and other case-control studies; the associations of the remaining 35 SNPs with NPC were novel. In addition, consistent with previous studies, exposure to occupational hazards, overconsumption of salt-cured foods, red meat, as well as low intake of fruits and vegetables were also associated with NPC risk. Conclusions: In short, this study confirmed and/or identified genetic, environmental and dietary risk factors associated with NPC susceptibility in a Southeast Asian population.
