Mobilizar: Capturing User Behavior with Mobile Digital Diaries

In this paper we present Mobilizar, a web-based mobile tool that facilitates the implementation and data collection of self-reported user behavior. Mobilizar was designed with both the researcher and the participant in mind. It provides investigators with a way to setup a new diary study in a matter of minutes and to electronically collect diary data from participants by using internet-enabled mobile devices. These devices promise to alleviate the burden of carrying a paper-and-pencil diary by instead using the participant’s own device. It also gives participants the flexibility to report their behavior in different ways such as making text, voice, or picture entries that fit their current situational constraints. In this paper, we describe the user interface design of Mobilizar and how it may be used to conduct diary studies with mobile devices

Efectos del ejercicio en la fisiología ocular

Toda actividad física extrema implica variaciones de los parámetros fisiológicos del deportista. Este artículo hace un repaso de los cambios sistémicos que se producen en el organismo durante la práctica deportiva y que, desde un punto de vista racional, podrían influir en el funcionamiento del sistema visual como son los cambios en el sistema cardiovascular, respiratorio, o neuro-endocrino. Posteriormente, y basándose en una revisión bibliográfica, realiza un análisis de la influencia directa de la práctica de actividad física sobre el sistema visual, tanto en las habilidades visuales (agudeza visual o acomodación, por ejemplo), como en parámetros anatómicos y fisiológicos como el ángulo irido-corneal, los diámetros pupilares, la presión intraocular, el flujo coroidal, la perfusión ocular o el diámetro de los vasos sanguíneos oculares. El artículo finaliza apuntando algunas líneas de investigación de interés dentro del ámbito de la fisiología ocular durante la práctica de actividad física, y algunas sugerencias para los investigadores que trabajen en el área de la visión deportiva

Efectes de l’exercici en la fisiologia ocular

Tota activitat física extrema implica variacions dels paràmetres fisiològics de l’esportista. Aquest article fa un repàs dels canvis sistèmics que es produeixen en l’organisme durant la pràctica esportiva i que, des d’un punt de vista racional, podrien influir en el funcionament del sistema visual, com ara els canvis en el sistema cardiovascular, respiratori, o neuroendocrí. Posteriorment, i prenent com a base una revisió bibliogràfica, realitza una anàlisi de la influència directa de la practica d’activitat física sobre el sistema visual, tant en les habilitats visuals (agudesa visual o acomodació, per exemple), com en paràmetres anatòmics i fisiològics, com ara l’angle iridocorneal, els diàmetres pupil·lars, la pressió intraocular, el flux coroïdal, la perfusió ocular o el diàmetre dels vasos sanguinis oculars. L’article finalitza esbossant algunes línies d’investigació d’interès dintre de l’àmbit de la fisiologia ocular durant la pràctica d’activitat física, i alguns suggeriments per als investigadors que treballin en l’àrea de la visió esportiva

Trilepton Signal for Supersymmetry at the Fermilab Tevatron Revisited

Within a wide class of models, the LEP2 lower limit of 95 GeV on the chargino mass implies gluinos are heavier than $\sim$300 GeV. In this case electroweak \tw_1\twb_1 and \tw_1\tz_2 production are the dominant SUSY processes at the Tevatron, and the extensively examined isolated trilepton signal from \tw_1\tz_2 production assumes an even greater importance. We update our previous calculations of the SUSY reach of luminosity upgrades of the Fermilab Tevatron in this channel incorporating ({\it i}) decay matrix elements in the computation of the momenta of leptons from chargino and neutralino decays, ({\it ii}) the trilepton background from $W^*Z^*$ and $W^*\gamma^*$ production which, though neglected in previous analyses, turns out to be the dominant background, and finally, ({\it iii}) modified sets of cuts designed to reduce these new backgrounds and increase the range of model parameters for which the signal is observable. We show our improved projections for the reach for SUSY of both the Fermilab Main Injector and the proposed TeV33 upgrade. We also present opposite sign same flavor dilepton invariant mass distributions as well as the $p_T$ distributions of leptons in SUSY trilepton events, and comment upon how the inclusion of decay matrix elements impacts upon the Tevatron reach, as well as upon the extraction of neutralino masses.Comment: final version to coincide with published manuscrip

Health and heating in the city of Temuco (Chile). Monetary savings of replacing biomass with PV system in the residential sector

The paper conducts a comprehensive analysis of replacing residential use of wood burning stoves for heating with photovoltaic systems for the generation of electricity using storage batteries (PV + storage systems). The research focuses on the city of Temuco (Southern Chile) as a case study, since this city has a high use of firewood for heating (80% of households) and also because this city has been declared by authorities as an area saturated with suspended particles. The total cost corresponds to the acquisition of systems. The reduction of monetary value of the impact of polluting emissions, resulting from the combustion of firewood, on health and traffic accidents is calculated. The interactive tool GDB Compare has been used to calculate the impact of pollution on health both in terms of attributable deaths and disability-adjusted life years. The monetary value of the impact on health has been calculated using two alternative approaches: the value of statistical life and the human capital approach. To identify firewood use requirements, heating degree–days has been used for temperatures ≤15 °C and ≤18 °C. The emissions avoided calculations have been refined, including emissions associated with the manufacture and transport of systems through the life cycle analysis. For all scenarios, the main results show that the savings outweigh the costs
