Global Englishes language teaching:Bottom-up curriculum implementation

In today's globalised world, the needs of English language learners have changed, particularly those learning to use the English language as a lingua franca. Growing research showcasing the global use of English as a lingua franca (ELF), the creativity of ELF users, and the diverse ways in which they negotiate successful communication in multilingual encounters has numerous implications for the field of TESOL. This article reports on a study with preservice and in‐service TESOL practitioners taking a Global Englishes for Language Teaching (GELT) option course in a 1‐year Master's in TESOL programme at a Russell Group university in the United Kingdom. The study explores attitudes towards GELT but also towards the proposals for, and barriers to, curriculum innovation as well as factors influencing such attitudes. Interviews (n = 21) and questionnaires (n = 47) revealed that attitudes remain norm bound, yet the study revealed a positive orientation towards GELT and provided insights into the feasibility of GELT‐related curriculum innovation and teacher education syllabus design. The study calls for more research with preservice and in‐service TESOL practitioners at different stages of the innovation process to ensure successful and sustainable GELT curricular innovation

Reliability of SleepStrip as a screening test in obstructive sleep apnea patients

Obstructive sleep apnea syndrome (OSAS) is a common sleep disorder and related to multiple conditions that cause mortality in adults. In the present study, reliability of SleepStrip, a disposable screening device for detection of OSAS, is tested. In this prospective, nonrandomized double-blinded single cohort study at an academic health center, the performance of the SleepStrip in detecting respiratory events and establishing an SleepStrip score (Sscore) in domestic use were compared to the apnea-hypopnea index (AHI) obtained by the standard polysomnography (PSG) recordings in the sleep laboratory. Forty-one patients who have the PSG results participated the study and wore the SleepStrips at home. Test efficiency rate was 75% and there was a positive correlation between PSG-AHI scores and Sscores (r = 0.71, p 30 levels. The SleepStrip has 100% specificity and positive predictive values, but it also has low negative predictive and sensitivity values. The SleepStrip is not a reliable screening test in differential diagnosis among simple snorers, mild, moderate and severe OSAS patients. However, high Sscores highly indicate the presence of moderate-severe OSAS. We can safely send these patients to split-night PSG and continuous, automatic, bi-level positive airway pressure (CPAP/BPAP/APAP) titration at the same night. The SleepStrip may increase the effective use of the sleep laboratories
