Työkulttuurien jännitteitä koulutusyhteisöissä
2019
Tarkastelemme artikkelissa jännitteitä koulutusyhteisöjen työkulttuureissa. Lähestymme aihetta opettajankoulutuksen kehittämiseen orientoituneesta koulutusmallista valmistuneiden opettajien kokemusten avulla. Tutkimuksen empiirisenä aineistona on 13 puolistrukturoitua yksilöhaastattelua, jotka kerättiin koulutusmalliin osallistuneilta opettajilta. Teoriasidonnaisessa sisällönanalyysissa keskityttiin yhteisön työkulttuuriin etsien myös sen vaikeammin havaittavia elementtejä, Scheinin (2017) sanoin perusolettamuksia.
 Tarkastelemme, miten yhteisöllisen ja kriittistä ammatillisuutta tukevan koulutusmallin anti on koettu ja miten sen vaikutukset ovat näyttäytyneet työelämässä. Tutkimuksemm…
Alianzas antiembalse y luchas hidroepistemológicas. Los retos de la gestión colectiva del agua en el Río Grande, Málaga, España
2018
En este artículo analizamos las luchas epistemológicas y retos que ha tenido el movimiento social en la subcuenca del río Grande frente a los diversos proyectos modernizadores que intentan transferir el agua rural hacia la ciudad de Málaga. El primero asociado a la construcción de un gran embalse y el segundo con la modernización de los sistemas de riego tradicionales. Concluimos que el reto está en desenmascarar el régimen de verdad que respalda los proyectos de modernidad hidráulica, reivindicar los derechos de uso y control colectivos del agua y así generar procesos de apropiación comunitaria para la defensa del río como un bien socio-ambiental, económico-cultural y político-epistemológi…
On Line Validation Exercise (OLIVE): A Web Based Service for the Validation of Medium Resolution Land Products. Application to FAPAR Products
2014
International audience; The OLIVE (On Line Interactive Validation Exercise) platform is dedicated to the validation of global biophysical products such as LAI (Leaf Area Index) and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation). It was developed under the framework of the CEOS (Committee on Earth Observation Satellites) Land Product Validation (LPV) sub-group. OLIVE has three main objectives: (i) to provide a consistent and centralized information on the definition of the biophysical variables, as well as a description of the main available products and their performances (ii) to provide transparency and traceability by an online validation procedure compliant with the CEO…
Designing a graphics processing unit accelerated petaflop capable lattice Boltzmann solver: Read aligned data layouts and asynchronous communication
2016
The lattice Boltzmann method is a well-established numerical approach for complex fluid flow simulations. Recently, general-purpose graphics processing units (GPUs) have become available as high-performance computing resources at large scale. We report on designing and implementing a lattice Boltzmann solver for multi-GPU systems that achieves 1.79 PFLOPS performance on 16,384 GPUs. To achieve this performance, we introduce a GPU compatible version of the so-called bundle data layout and eliminate the halo sites in order to improve data access alignment. Furthermore, we make use of the possibility to overlap data transfer between the host central processing unit and the device GPU with com…
Hölder regularity for the gradient of the inhomogeneous parabolic normalized p-Laplacian
2018
In this paper, we study an evolution equation involving the normalized [Formula: see text]-Laplacian and a bounded continuous source term. The normalized [Formula: see text]-Laplacian is in non-divergence form and arises for example from stochastic tug-of-war games with noise. We prove local [Formula: see text] regularity for the spatial gradient of the viscosity solutions. The proof is based on an improvement of flatness and proceeds by iteration.
Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
Remarks on regularity for p-Laplacian type equations in non-divergence form
2018
We study a singular or degenerate equation in non-divergence form modeled by the $p$-Laplacian, $$-|Du|^\gamma\left(\Delta u+(p-2)\Delta_\infty^N u\right)=f\ \ \ \ \text{in}\ \ \ \Omega.$$ We investigate local $C^{1,\alpha}$ regularity of viscosity solutions in the full range $\gamma>-1$ and $p>1$, and provide local $W^{2,2}$ estimates in the restricted cases where $p$ is close to 2 and $\gamma$ is close to 0.
Fractional Hardy inequalities and visibility of the boundary
2013
We prove fractional order Hardy inequalities on open sets under a combined fatness and visibility condition on the boundary. We demonstrate by counterexamples that fatness conditions alone are not sufficient for such Hardy inequalities to hold. In addition, we give a short exposition of various fatness conditions related to our main result, and apply fractional Hardy inequalities in connection to the boundedness of extension operators for fractional Sobolev spaces.
Recovery of mobility function and life-space mobility after ischemic stroke: the MOBITEC-Stroke study protocol
2020
Abstract Background Stroke is a major cause of disability and stroke incidence increases with age. Stroke frequently results in permanent limitations of mobility, and, consequently, the need for the help of others in activities of daily living. In order to optimize rehabilitative efforts and their functional outcomes, detailed knowledge of the functional recovery process, regarding mobility, is needed. Objectives of the MOBITEC-Stroke study are: 1.) To characterize mobility, including lower extremity physical function (LEPF) and life space (the geospatial extent of all of a person’s movements), and changes in mobility within the first year after stroke. 2.) To identify and characterize subg…
