Show moreStudy objectives: Sleep state misperception is common in various sleep disorders, especially in chronic insomnia with a prevalence ranging between 9-50%. Most prior studies used nocturnal polysomnography (PSG) for the identification of sleep state misperception during nighttime. Our objective was to assess sleep state misperception during daytime in people with sleep disorders with excessive daytime sleepiness (EDS).Methods: In this prospective observational study, we assessed the occurrence of, and factors influencing sleep state misperception in consecutive patients undergoing a routine multiple sleep latency test (MSLT) in a tertiary sleep-wake centre included between 2014 and 2017. Mixed models were applied to assess the influence of patients' clinical data on sleep state perception.Results: People with narcolepsy type 1 (NT1, n = 33) and type 2 (NT2, n = 14), idiopathic hypersomnia (IH, n = 56), obstructive sleep apnea (OSA, n = 31) and insufficient sleep syndrome (ISS, n = 31) were included. The prevalence of both classical and reverse sleep state misperception did not differ between the sleep disorders (mean 25%, range 8-37%) after correction for sleep stage, sleep onset latency and age. Longer sleep onset latency and reaching only non-rapid eye movement (REM) sleep stage 1 were significant predictors for classical sleep state misperception.Conclusions: Sleep state misperception is common in people with NT1 and NT2, IH, OSA, and ISS. Classical sleep state misperception is more frequent in patients with longer sleep onset latencies who only reach non-REM sleep stage 1 during a nap. (C) 2020 Elsevier B.V. All rights reserved.

Show moreThree Christian films have become popular in the Commune of Cobly of today's Republic of Benin, notably the American "Jesus Film" (1979), the American-Ivorian film "La Solution" (1994) and the Beninese video film "Yatin: Lieu de souffrance" (2002). The discussion centres on how people receive and understand these films together with the digital video technology that facilitate their recent success. Christian films are so important in this part of Benin that the question needs to be raised whether Christianity is shifting from a religion of the book towards a religion of film. The theoretical starting point is semiotics, a theory that has been foundational not only for film, media and media reception studies, but more recently also for the study of materiality. This thesis' main theoretical contribution is a critique of semiotics, arguing that this theory, which has been foundational to Western science, is in fact too limiting. Semiotics, even in its Peircean orientation, cannot sufficiently explain how people in the Commune of Cobly understand shrines, film and media more generally, both through their material manifestations and interactively in terms of communication. Instead, a process called "presencing", which goes beyond semiotics, can explain better people's understanding of shrines and media. Show less
