Comparaison de différents plans de sondage et construction de bandes de confiance pour l'estimation de la moyenne de données fonctionnelles : une ill…
2012
Accepté pour publication dans Survey Methodology/Techniques d'Enquêtes.; Lorsque les variables étudiées sont fonctionnelles et que les capacités de stockage sont limitées ou que les coûts de transmission sont élevés, les sondages, qui permettent de sélectionner une partie des observations de la population, sont des alternatives intéressantes aux techniques de compression du signal. Notre étude est motivée, dans ce contexte fonctionnel, par l'estimation de la courbe de charge électrique moyenne sur une période d'une semaine. Nous comparons différentes stratégies d'estimation permettant de prendre en compte une information auxiliaire telle que la consommation totale de la période précédente. …
Geostatistical computing of acoustic maps in the presence of barriers
2009
Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.
Aplicaciones publicitarias para móvil: conocimiento, actitudes, motivos de uso y valoración por parte de los adolescentes españoles
2012
La publicidad móvil ha ido captando la atención de los anunciantes en los últimos años convirtiéndose en un sector emergente de la actividad publicitaria actual. Fruto de este interés, y del propio dinamismo del sector, los anunciantes han ido experimentando con numerosas estrategias y herramientas, desde los SMS y MMS hasta el bluetooth o los códigos QR, con el objetivo de ser más eficaces a la hora de desarrollar sus comunicaciones de marketing. Las aplicaciones publicitarias para móviles son la penúltima de las herramientas que el medio pone a disposición de los anunciantes. El exponencial crecimiento en el uso de aplicaciones para móviles por parte de los usuarios parece augurar un buen…
A holistic perspective on the theoretical foundations for ICT4D research
2018
While many theories have guided research Information and Communication Technologies for Development (ICT4D), we are yet to construct a clear and coherent narrative that would help us answer the question of how ICT fosters development in underdeveloped communities. In this paper, we argue that one of the main reasons for this is that our holistic understanding of ICT4D is seldom grounded in theories to understand the core areas that define the field, namely, ICT, Development, and, ‘4’ which are the transformative processes that link the two. Through a brief literature review, we list theories that have informed ICT4D research in each of these areas. We present examples of theories, namely, C…
Determining the effects of Eugenol on the bond strength of resin-based restorative materials to dentin : a meta-analysis of the literature
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/2076-3417/10/3/1070/htm Este artículo pertenece al número especial " Permanent and long-term biodegradable biomaterials". The aim of this study was to determine whether the residual presence of eugenol in coronal dentin may compromise the bond strength of resin-based restorative materials. A search was performed on MEDLINE/Pubmed, Scopus, and by hand search for relevant papers. No restriction was applied for language and publication date. The studies selected for analysis tested specimens with reduced size (micro-shear bond strength ( SBS) and micro-tensile bond strength ( TBS)) of adhesive systems and resin-bas…
Teoría de la educación : educación y cultura en la sociedad de la información
2008
La educación para la igualdad requiere de la implicación de todas y cada una de las agencias que participan de este proceso. En este trabajo hemos querido conocer en qué medida los videojuegos más vendidos y utilizados por la población infantil y juvenil transmiten contenidos que contribuyen a su educación para la igualdad o, por el contrario, la dificultan. Para ello hemos analizado el contenido de los diez videojuegos más jugados por menores y adolescente, atendiendo a los valores y disvalores que transmiten, centrando nuestra atención en la representación de modelos de mujer y roles de género. Por último, hemos tratado de establecer una serie de conclusiones y orientaciones pedagógicas, …
Identifiability problem for recovering the mortality rate in an age-structured population dynamics model
2014
In this article is studied the identifiability of the age-dependent mortality rate of the Von Foerster–Mc Kendrick model, from the observation of a given age group of the population. In the case where there is no renewal for the population, translated by an additional homogeneous boundary condition to the Von Foerster equation, we give a necessary and sufficient condition on the initial density that ensures the mortality rate identifiability. In the inhomogeneous case, modelled by a non-local boundary condition, we make explicit a sufficient condition for the identifiability property, and give a condition for which the identifiability problem is ill-posed. We illustrate this latter case wit…
Ambient Air Pollution Increases the Risk of Cerebrovascular and Neuropsychiatric Disorders through Induction of Inflammation and Oxidative Stress
2020
Exposure to ambient air pollution is a well-established determinant of health and disease. The Lancet Commission on pollution and health concludes that air pollution is the leading environmental cause of global disease and premature death. Indeed, there is a growing body of evidence that links air pollution not only to adverse cardiorespiratory effects but also to increased risk of cerebrovascular and neuropsychiatric disorders. Despite being a relatively new area of investigation, overall, there is mounting recent evidence showing that exposure to multiple air pollutants, in particular to fine particles, may affect the central nervous system (CNS) and brain health, thereby contributing to …
Airlines Customer Segmentation in the Hyper-Competition Era
2019
As the airline industry reaches its maturity, so do the passengers who are looking for more sophistication in terms of the products and services they buy or expect. Offering a large array of services to customers with different expectations who await customization along their journey has become more challenging for airlines all over the world. Coping with changes in a volatile environment means that airlines need to redefine their customer segmentation, evolving from a social-demographic to a more complicated behavioral approach which encompasses the whole traveling experience and the way airlines deliver at every touching point.
The Route Development Strategies of Romanian Airports: A Key Challenge in Modern Aviation
2018
Airport route development can be defined as a complex process carried out by airports, encouraging airlines to launch new routes or increase frequencies on already served destinations. The deregulated aviation environment helped airports to find new and innovative ways to compete directly with each other for a limited airline capacity, engaging with airlines and proving the airport route development strategy and airline needs meet at a certain point. The future prosperity of the communities the airports serve, depends on the efforts of the route development team and their focused aviation marketing strategy. A huge responsibility to attract what is best for the community as well as a good c…
