This paper analyses “A Message to America,” the 2014 ISIS video that presents the beheading of American photojournalist James Foley. This short film served as a model for the more than 200 graphically violent videos posted online by the terrorist group before the fall of the caliphate in 2019. The main objective of this research is to question the truth-value of violent ISIS videos and to advocate a critical approach to them. To this end, four key issues need to be (...) explored: the quality of the videos; their status as art, documentary, or propaganda; their target audiences; and the purpose of the message being conveyed to each of those audiences. To deconstruct the mechanisms employed by the constructed fallacy of this video and critically expose its literal and metaphorical meaning, we use textual analysis, the methodological tool developed in Greimasian semiotics. The results reveal a carefully planned text with a clearly recognizable narrative structure (crime and punishment). This video is a propaganda documentary that makes use of the tools of fiction to stage a real event: Foley dies, but his death is not shown on camera; it is only staged. Targeting two different audiences, an implicit Muslim viewer, and an explicit Western viewer, the text can be interpreted as a crossing of gazes between East and West. (shrink)

Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)
