El arbitraje en el procedimiento administrativo de registro de marcas en Brasil
2015
La investigación se propone realizar un estudio del arbitraje aplicado en el procedimiento administrativo del registro de marcas en Brasil. Frente a la aceptación del arbitraje en Brasil en el ámbito privado, la propuesta de la investigación consiste en ampliar su uso en áreas especiales, tales como el derecho de marcas, aún en el marco del procedimiento administrativo de registro. En este contexto, se plantea la cuestión de fondo o sea, el problema que deseamos investigar: ¿que es nuestro problema de investigación, es decir, ¿Es que se puede (o como se podría ) aplicar el arbitraje en el procedimiento administrativo del registro de marcas en Brasil? Para responder al problema de la investi…
Évaluer les trajectoires scolaires à l'aune de la "méritocratie" ou "les trajectoires scolaires les plus longues sont-elles toujours le fait des meil…
1992
International audience; Cet article présente une synthèse des travaux empiriques réalisés de 1985 à 1992 autour des inégalités sociales de trajectoires scolaires. Loin de constituer le reflet fidèle d'inégalités de résultats scolaires, les différenciations de cursus incorporent pour une part non négligeable des inégalités dans le "choix" des familles. En outre, c'est toute la carrière de l'élève qui apparait affectée par le contexte où prend place sa scolarité, non sans incidence en termes d'inégalités sociales. Ceci interroge sur le fonctionnement de l'école, notamment au niveau collège où se génèrent la plus grande part des inégalités, mais aussi sur les possibilités de réforme d'une inst…
EmPeCemos: un programa multicomponente para la prevención indicada de los problemas de conducta y el abuso de drogas
2009
En la última década, un amplio número de investigaciones ha permitido constatar la existencia de trayectorias de desarrollo desadaptativas, asociadas a problemas de conducta de inicio temprano. Estas trayectorias, en las que se implica una compleja cadena de factores familiares, escolares y socioemocionales, dan lugar a desajustes comportamentales crónicos y severos, de difícil tratamiento, incluyendo comportamientos antisociales y abuso de drogas. Por ello, la investigación en prevención subraya la necesidad de una intervención temprana que, actuando sobre los individuos en alto riesgo y su entorno, permita detener el avance hacia patrones severos de desadaptación. En esta línea, se desarr…
The relationship of symptom dimensions with premorbid adjustment and cognitive characteristics at first episode psychosis: Findings from the EU-GEI s…
2021
Premorbid functioning and cognitive measures may reflect gradients of developmental impairment across diagnostic categories in psychosis. In this study, we sought to examine the associations of current cognition and premorbid adjustment with symptom dimensions in a large first episode psychosis (FEP) sample. We used data from the international EU-GEI study. Bifactor modelling of the Operational Criteria in Studies of Psychotic Illness (OPCRIT) ratings provided general and specific symptom dimension scores. Premorbid Adjustment Scale estimated premorbid social (PSF) and academic adjustment (PAF), and WAIS-brief version measured IQ. A MANCOVA model examined the relationship between symptom di…
A diversity of patterns: 10-year trajectories of men and women diagnosed with psychosis for the first time. A time-geographic approach
2020
People with severe mental illness face a different interventional landscape compared to some decades ago, when mental hospitals were dominant, in Sweden as well as in the rest of the Western world. The aim of the research reported in this article was to follow men and women diagnosed with psychosis for the first time over a 10-year period, and to explore what interventions they experienced. The interventions, here defined as "spheres", were either community-based or institutional. A third sphere represents no interventions. Based on data from registers and using a time-geographic approach, the individuals were visualised as 10-year trajectories where their transitions between the different …
A Novel Non-Stationary Channel Model Utilizing Brownian Random Paths
2014
This paper proposes a non-stationary channel model in which real-time dynamics of the mobile station (MS) are taken into account. We utilize Brownian motion (BM) processes to model targeted and non-targeted dynamics of the MS. The proposed trajectory model consists of both drift and random components to capture both targeted and non-targeted motions of the MS. The Brownian trajectory model is then employed to provide a non-stationary channel model, in which the scattering effects of the propagation area are modelled by a non-centred one-ring geometric scattering model. The starting point of the motion is a fixed point in the propagation environment, whereas its terminating point is a random…
Trajectory robust control of autonomous quadcopters based on model decoupling and disturbance estimation
2021
In this article, a systematic procedure is given for determining a robust motion control law for autonomous quadcopters, starting from an input–output linearizable model. In particular, the suggested technique can be considered as a robust feedback linearization (FL), where the nonlinear state-feedback terms, which contain the aerodynamic forces and moments and other unknown disturbances, are estimated online by means of extended state observers. Therefore, the control system is made robust against unmodelled dynamics and endogenous as well as exogenous disturbances. The desired closed-loop dynamics is obtained by means of pole assignment. To have a feasible control action, that is, the fo…
ROS/Gazebo-Based Simulation of Quadcopter Aircrafts
2018
The main purpose of this work is to present a tutorial description on how to design and develop an observer, which is capable of estimating the position and the orientation of a drone commanded by a controller, whose shape and structure are unknown. Starting from Newton's and Euler's laws, a mathematical model describing the dynamics of a quadcopter has first been obtained. By linearizing this model it is possible to implement a Luenberger observer and validate it with simulations in a Linux environment, thanks to the use of the Ardupilot controller and the Gazebo simulator. Finally, starting from the results obtained from the simulation, it is possible to evaluate the error made in the est…
Identification of patterns og change on mongitudinal data, illustrated by two exemples : study of hospital pathways in the management of cancer. Cons…
2014
Context In healthcare domain, data mining for knowledge discovery represent a growing issue. Questions about the organisation of healthcare system and the study of the relation between treatment and quality of life (QoL) perceived could be addressed that way. The evolution of technologies provides us with efficient data mining tools and statistical packages containing advanced methods available for non-experts. We illustrate this approach through two issues: 1 / What organisation of healthcare system for cancer diseases management? 2 / Exploring in patients suffering from metastatic cancer, the relationship between health-related QoL perceived and treatment received as part of a clinical tr…
La crise inscrit-elle les jeunes en France dans une dynamique de gagnants-perdants ?
2016
International audience; L'entrée des jeunes dans la vie active est particulièrement sensible aux aléas conjoncturels. L'objet de cette communication est d'appréhender les conséquences de la crise financière de 2008 sur les premières années de vie active des jeunes en mobilisant la théorie de la segmentation du marché du travail formulée par Doeringer et Piore (1971). Dans le sens de cette théorie, les emplois précaires ou instables seraient davantage l'apanage des jeunes en début de vie professionnelle. Mais qu'en est-il en temps de crise ? S'agit-il d'un point de passage plus ou moins inévitable pour toutes et tous, ou l'emploi précaire demeure-t-il pour une main-d'oeuvre captive tels les …
