Social Innovation Toward a Meaningful Everyday Life for Nursing Home Residents: An Ethnographic Study
2021
Background: The literature shows that innovation, which includes culture change, may be important to create a meaningful everyday life for nursing home residents. However, there is a gap in how social innovation practices may contribute to this. The theoretical discourse for the study is person-centered care.Aim: The main aim was to explore phenomena within social innovation that can contribute to improving nursing home residents’ everyday lives.Design and Method: This study uses an ethnographic design with observations and interviews in two nursing homes in Southern Norway.Findings: The main theme was that social innovation within working practices in nursing homes includes phenomena that …
L’engagement des chercheurs dans la vulgarisation scientifique
2012
International audience; Quelle attitude ont les chercheurs vis-à-vis de la vulgarisation scientifique ? Voilà une question que tout médiateur scientifique est amené à se poser. Elle intéresse aussi les gouvernements et les grandes institutions scientifiques qui incitent les chercheurs à communiquer auprès du grand public et cherchent des solutions pour améliorer cette communication.Nous avons recherché des études et des enquêtes qui, depuis 1992, auraient proposé des diagnostics sur l’attitude, l’intérêt et surtout l’engagement des chercheurs dans cette pratique de vulgarisation. Notre propos s’articulera autour d’une étude clé, publiée en 2007 par Ellen Poliakoff et Thomas L Webb qui s’int…
Approximation of pore space with ellipsoids: a comparison of a geometrical method with a statistical one.
2018
International audience; We work with tomographic images of pore space in soil. The images have large dimensions and so in order to speed-up biological simulations (as drainage or diffusion process in soil), we want to describe the pore space with a number of geometrical primitives significantly smaller than the number of voxels in pore space. In this paper, we use the curve skeleton of a volume to segment it into some regions. We describe the method to compute the curve skeleton and to segment it with a simple segment approximation. We approximate each obtained region with an ellipsoid. The set of final ellipsoids represents the geometry of pore space and will be used in future simulations.…
Towards sustainable mobility : Transformative scenarios for 2034
2022
Highlights • Increasing the share of walking and cycling is one of the building blocks of sustainable mobility transformation. • We organised an online Delphi survey for 30 walking and cycling experts during the first wave of COVID-19 pandemic. • Disaggregative Delphi analysis is elaborated based on the systemic restructuring of qualitative data. • Transport experts’ views of the future are described in the form of five walking and cycling scenarios up to 2034. • The results can be used for strategic transport planning and policy, and for identifying instruments for walking and cycling promotion in urban areas. Increasing the share of walking and cycling is one of the building blocks of sus…
Daily rhythms of young children in the 24/7 economy : A comparison of children in day care and day and night care
2017
The study explored temporal variation in children’s moods and compared children in regular day care with those in day and night care in Finland. To examine variation in children’s experiences, a mobile diary was used. The participants comprised 32 young children and their parents and day care personnel. Adults evaluated children’s moods three times daily over 1 week. A clear weekday–weekend rhythm was found among children in day care, who displayed more negative moods, due to frequent hurried mornings. Children in day and night care had more irregular mood rhythms. Boys were evaluated as displaying more negative moods than girls. peerReviewed
Estimating QCD uncertainties in Monte Carlo event generators for gamma-ray dark matter searches
2018
Motivated by the recent galactic center gamma-ray excess identified in the Fermi-LAT data, we perform a detailed study of QCD fragmentation uncertainties in the modeling of the energy spectra of gamma-rays from Dark-Matter (DM) annihilation. When Dark-Matter particles annihilate to coloured final states, either directly or via decays such as $W^{(*)}\to q\bar{q}'$, photons are produced from a complex sequence of shower, hadronisation and hadron decays. In phenomenological studies, their energy spectra are typically computed using Monte Carlo event generators. These results have however intrinsic uncertainties due to the specific model used and the choice of model parameters, which are diffi…
Computational Techniques for the Analysis of Small Signals in High-Statistics Neutrino Oscillation Experiments
2020
The current and upcoming generation of Very Large Volume Neutrino Telescopes – collecting unprecedented quantities of neutrino events – can be used to explore subtle effects in oscillation physics, such as (but not restricted to) the neutrino mass ordering. The sensitivity of an experiment to these effects can be estimated from Monte Carlo simulations. With the high number of events that will be collected, there is a trade-off between the computational expense of running such simulations and the inherent statistical uncertainty in the determined values. In such a scenario, it becomes impractical to produce and use adequately-sized sets of simulated events with traditional methods, such as M…
Measurement of θ13 in Double Chooz using neutron captures on hydrogen with novel background rejection techniques
2016
The Double Chooz collaboration presents a measurement of the neutrino mixing angle θ[subscript 13] using reactor [bar over ν[subscript e]] observed via the inverse beta decay reaction in which the neutron is captured on hydrogen. This measurement is based on 462.72 live days data, approximately twice as much data as in the previous such analysis, collected with a detector positioned at an average distance of 1050 m from two reactor cores. Several novel techniques have been developed to achieve significant reductions of the backgrounds and systematic uncertainties. Accidental coincidences, the dominant background in this analysis, are suppressed by more than an order of magnitude with respec…

Intrinsic backgrounds from Rn and Kr in the XENON100 experiment
2018
In this paper, we describe the XENON100 data analyses used to assess the target-intrinsic background sources radon ([InlineMediaObject not available: see fulltext.]), thoron ([InlineMediaObject not available: see fulltext.]) and krypton ([InlineMediaObject not available: see fulltext.]). We detail the event selections of high-energy alpha particles and decay-specific delayed coincidences. We derive distributions of the individual radionuclides inside the detector and quantify their abundances during the main three science runs of the experiment over a period of ∼4years, from January 2010 to January 2014. We compare our results to external measurements of radon emanation and krypton concentr…
