Evaluating the Public's Reaction to Simulated Alerts on Mobile Phones in France: Scale Effects, and Challenges

2022

International audience; In case of sudden and extreme life-threatening situation, the most efficient system fulfils the requirement of mobile phone emergency alerting information services. But how much information and what type of content must be used in a textual message, and how adapt this alert to a large audience and diversified contexts? This paper proposes to address this challenge, 1) by presenting results obtained in France during simulated "alerting days", with sampling revealing the perception and understanding of SMS and CB by a non-specialized audience (161 respondents), and 2) by comparing findings obtained in different contexts (students and teaching staff in a university, cri…

Sur l’importance des disques et du recording dans la musique populaire et la techno

2005

International audience; Depuis qu'Edison a inventé le phonographe un nouveau mode de stockage de la musique est venu s'ajouter au corps des individus et à la notation : les disques. Cela signifie, qu'en plus d'aller à la musique (jouer d'un instrument ou assister à un évènement musical), la musique vient à nous. C'est donc par l'intermédiaire des enregistrements que, dans une très grande mesure, nous découvrons, aimons, apprenons et transmettons la musique. Autrement dit, ce que l'on appelait jadis, et assez improprement, la culture orale, a trouvé son médium, un objet léger et bourré d'informations précieuses qui circule et s'échange facilement.

Extending existential feeling through sensory substitution

2023

AbstractIn current philosophy of mind, there is lively debate over whether emotions, moods, and other affects can extend to comprise elements beyond one’s organismic boundaries. At the same time, there has been growing interest in the nature and significance of so-called existential feelings, which, as the term suggests, are feelings of one’s overall being in the world. In this article, I bring these two strands of investigation together to ask: can the material underpinnings of existential feelings extend beyond one’s skull and skin? To begin, I introduce and adopt a componential-systemic view of extended affectivity. In doing so, I specify the vehicle externalist criteria for extension em…

Teacher and student teacher views of agency in feedback

2022

The present study compares the feedback themes that groups of teachers (n = 5) and student teachers (n = 15) discussed in a professional development programme concerning teachers’ classroom interaction and formative assessment, and the agents they assigned the feedback to. The results of the thematic analysis show little variation with the conversation themes between the groups, but they did show more with the appointed agents of feedback themes. The teachers assigned feedback themes to the teacher and the students, as student teachers assigned them to the teacher and the learning environment. By referring to feedback as the shared responsibility of the teacher and students, the teachers de…

Diseño y validación de un dispositivo para la cuantificación de la lordosis lumbar basado en sensores inerciales

2017

El dolor de espalda sigue siendo un problema importante en la actualidad y, la lumbalgia es una de sus consecuencias más directas y habituales. Se puede decir que es un preocupante problema a nivel mundial y no se conocen estrategias de tratamiento que realmente sean eficaces. Es la enfermedad reumática más atendida en centros de salud y clínicas y tiene como resultado un considerable gasto financiero, de mano de obra y de costes sociales. Se ha visto que, si bien numerosas patologías se han asociado al dolor lumbar, a menudo es difícil establecer una causa clara o un factor para determinar el origen de ese dolor en la persona. La mayoría de lumbalgias atendidas se etiquetan como "no especí…

Monitoring the effects of therapeutic interventions in depression through self-assessments

2021

The treatment of major psychiatric disorders is an arduous and thorny path for the patients concerned, characterized by polypharmacy, massive adverse side effects, modest prospects of success, and constantly declining response rates. The more important is the early detection of psychiatric disorders prior to the development of clinically relevant symptoms, so that people can benefit from early interventions. A well-proven approach to monitoring mental health relies on voice analysis. This method has been successfully used with psychiatric patients to ‘objectively’ document the progress of improvement or the onset of relapse. The studies with psychiatric patients over 2-4 weeks demonstrated …

Global linear feedback control for the generalized Lorenz system

2006

Abstract In this paper we show how the chaotic behavior of the Chen system can be controlled via feedback technique. We design both a nonlinear feedback controller and a linear one which globally regulate the closed-loop system states to a given point. We finally show that our approach works also for the whole family of the generalized Lorenz system.

Nonlinear Feedback Control and Stability Analysis of a Proof-of-Work Blockchain

2017

In this paper a novel feedback controller and stability analysis of a blockchain implementation is developed by using a control engineering perspective. The controller output equals the difficulty adjustment in the mining process while the feedback variable is the average block time over a certain time period. The computational power (hash rate) of the miners is considered a disturbance in the model. The developed controller is tested against a simulation model with constant disturbance, step and ramp responses as well as with a high-frequency sinusoidal disturbance. Stability and a fast response is demonstrated in all these cases with a controller which adjusts it's output at every new blo…
