Avant les gaz lacrymogènes. Les liaisons dangereuses du maintien de l'ordre, de la police politique et de la police judiciaire en France durant la Tr…
2008
L’objet de cet article est de montrer que le maintien de l’ordre ne se reduit pas au seul moment de la confrontation entre des fauteurs de troubles et la force publique. La police judiciaire et le renseignement administratif s’enchevetrent dans cette activite qui designe plus le cadre global de l’action des policiers avant la Premiere Guerre mondiale qu’un registre specialise et autonome. Or, la collision de la police judiciaire et de la police politique durant les episodes de maintien de l’ordre produit un effet inattendu en amenant les gendarmes et les policiers a transgresser les reglements presidant a leur activite.
Conceptualizing engagement in the mobile context
2016
This conceptual study answers how engagement is defined and conceptualized in the mobile service/technology context. A systematic literature review was conducted in the fields of business and human-computer interactions to achieve this objective. The 22 studies included in the final analysis are classified into two categories that distinguish the main perspectives of mobile engagement. This study demonstrates that prior research has either conceptualized mobile engagement as a behavioral activity (i.e., using or interacting with mobile service/technology) or has perceived it holistically as customer engagement that occurs in a mobile environment. Based on the analysis, it is proposed that c…
CREAPP K6-12: Tool to evaluate the creative potential of app oriented to the design of personal digital storytelling
2018
An instrument is presented that allows primary school teachers to evaluate the potentiality to develop creativity that have playful online app K6-12 focused on the development of digital storytelling (DST), so they can select those that can be used in the classroom for that purpose. The instrument validated consists of 48 indicators associated with the six dimensions of the creativity: flexibility, originality, fluency, problem solving, elaboration of products and co-edition and dissemination. It was designed based on the opinions of experts in creativity and Information and Communication Technologies of the didactic field, theory of education and methodology; also with the assessments and…
More firms, more competition? The case of the fourth operator in France's mobile phone market
2010
Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…
Sistemas de respuesta inmediata en el aula: una experiencia de evaluación formativa en educación física.
2017
Resumen: La necesidad de mejorar los procesos de evaluación es una prioridad para el profesorado y las instituciones educativas. Pese a ello, implementar la evaluación formativa y democrática de calidad en disciplinas como educación física, resulta difícil por las barreras existentes: la ratio alumnado-profesorado por curso y por clase, el escaso tiempo de acción didáctica o por la dificultad de obtener información sobre los tres dominios de aprendizaje disciplinares psicomotor, cognitivo y socio-afectivo (Díaz, 2015; Krause, O'Neil, & Dauenhauer 2017). Las TIC, especialmente el Mobile learning, ofrecen un inédito escenario de posibilidades para mejorar la evaluación del alumnado, del profe…
Practical procedure for verification of compliance of digital mobile radio base stations to limitations of exposure of the general public to electrom…
2002
In the last few years, society has witnessed the installation of an ever increasing number of radio base stations as a necessity for handling new capabilities and services to the large number of users. This rapid development of wireless networks, however, has induced a marked mistrustful attitude in people, who fear possible biological effects of electromagnetic emissions from mobile communications base stations. While there are guidelines on the limitation of human exposure to electromagnetic fields (emf ), there is no harmonised standard measurement procedure to evaluate compliance with the limits on exposure in the vicinity of a base station. The measurement procedure has to be practical…
A novel pressure regulation system based on Banki hydro turbine for energy recovery under in-range and out-range discharge conditions
2021
Abstract Efficiency improvement of water distribution networks needs to be in place to guarantee a long life period under suitable operating conditions. Excessive pressure is among the well-known issues encountered in water distribution networks which can cause strength damages to the piping system. In order to overcome this drawback and to reach a suitable water pressure delivery, the present work suggests a novel pressure regulation system. This regulation system is consisting of a Banki turbine equipped with a mobile flap as a control device. The suggested pressure regulation system was experimentally and numerically investigated under in-range i.e. like actual water distribution network…
UMTS radio networks
2006
Publisher Summary This chapter reviews the contributions to the UMTS radio network planning, with the optimization being provided from COST 273 and the real-time tuning, which is related to RRM. The results on UTRAN performance evaluation by the means of simulation tools are also discussed. The UMTS planning includes processes like: the propagation and traffic models, the aspects of parameter planning, and the automatic planning algorithms. An accurate ray-tracing model integrated in a UMTS-capable planning tool allows the radio network planner to reach optimal numbers for the BS deployment and configuration while meeting the service level requirements. Ray tracing can identify the problem …
Unraveling the Complexity of Tourist Experience with NFC Technology and Mobile Wallets
2014
By considering the tourist experience as a complex dynamic system, in this paper we depict the traveler as a kybernetes (κυβeρνήτης is the ancient Greek word for ‘sea captain’, ‘steersman’, or ‘governor’) in search of powerful tools to help him or her to obtain directions in the mare magnum of complexity, overcoming the fear of action and taking decisions. We focus our attention on the key role of Near Field Communication technology and mobile wallet as ‘attenuators of complexity’ in the travel and tourism industry.
Assistive robotic walker parameter identification for estimation of human thrust without force sensors
2017
In this paper we propose a parameter identification procedure for the wheel-motor dynamic of a robotic walker, i.e. a commercial trolley for elderly people endowed with cognitive, sensing and guidance capabilities. The objective of the wheel-motor dynamic model is to generate a suitable time reference to be used in an estimation algorithm. The ultimate goal of the estimation algorithm is to retrieve the thrust, i.e. torque and force, that the older adult user of the robotic walker applies to the platform. These quantities are of paramount importance in order to adopt intelligent and comfortable walker guidance algorithms. The novelty of this approach is the avoidance of additional costly se…
