The effects of grazing history, soil properties and stand structure on the communities of saprotrophic fungi in wood-pastures
2022
Wood-pastures are threatened anthropogenic biotopes that provide habitat for an extensive group of species. Here we studied the effect of management, grazing intensity, time since abandonment, historical land-use intensity, soil properties and stand conditions on communities of saprotrophic fungi in wood-pastures in Central Finland. We found that the proportion of broadleaved trees and soil pH are the major drivers in the communities of saprotrophic fungi in these boreal wood-pastures. In addition, tree species richness, soil moisture, historical land-use intensity and time since abandonment affected the communities of saprotrophic fungi. Current management or grazing intensity did not have…
Setting Individual Goals for Pupils with Profound Intellectual and Multiple Disabilities : Engaging in the Activity Area-Based Curriculum Making
2021
The activity area-based curriculum model (AACM) is used in the Finnish basic education to support pupils—most of whom have profound intellectual and multiple disabilities (PIMD)—who could benefit more from skills that advance independent life coping. Existing studies have concentrated mainly on the Individual Education Plan (IEP) goal-setting process for pupils with milder disabilities than PIMD and have consistently demonstrated significant barriers in the process. This study explores the collaborative IEP goal-setting process for pupils with the AACM. Sixty-five Finnish special education teachers using the AACM participated in the study. Semi-structured interviews were analysed with thema…

High precision numerical approach for Davey–Stewartson II type equations for Schwartz class initial data
2020
We present an efficient high-precision numerical approach for Davey–Stewartson (DS) II type equa- tions, treating initial data from the Schwartz class of smooth, rapidly decreasing functions. As with previous approaches, the presented code uses discrete Fourier transforms for the spatial dependence and Driscoll’s composite Runge–Kutta method for the time dependence. Since DS equations are non-local, nonlinear Schrödinger equations with a singular symbol for the non-locality, standard Fourier methods in practice only reach accuracy of the order of 10−6or less for typical examples. This was previously demonstrated for the defocusing integrable case by comparison with a numerical approach for …
The pblm package: semiparametric regression for bivariate categorical responses in R
2014
We present an R package to fit semiparametric regression models for two categorical responses. It works for both nominal and ordered responses and several types of logits can be specified. Proportional, non-proportional and partial proportional odds models can be fitted, with marginal and association parameters estimated in a parametric or semiparametric way, via penalized maximum likelihood estimation. An application to show the potential of the package is carried out on a data set of Italian university students.
Gaussian processes retrieval of crop traits in Google Earth Engine based on Sentinel-2 top-of-atmosphere data.
2022
The unprecedented availability of optical satellite data in cloud-based computing platforms, such as Google Earth Engine (GEE), opens new possibilities to develop crop trait retrieval models from the local to the planetary scale. Hybrid retrieval models are of interest to run in these platforms as they combine the advantages of physically-based radiative transfer models (RTM) with the flexibility of machine learning regression algorithms. Previous research with GEE primarily relied on processing bottom-of-atmosphere (BOA) reflectance data, which requires atmospheric correction. In the present study, we implemented hybrid models directly into GEE for processing Sentinel-2 (S2) Level-1C (L1C)…
« L’homme-à-fourchette ». La construction du convive-modèle à la table de Buckingham Palace
2021
“Every meal is a lesson learned”. The Victorian saying warns of the risk of punishment that every guest constantly incurs. These sanctions often relate to the way in which one approaches, one selects, one handles the cutlery on the table. Indeed, the construction of the ideal guest, of his way of being with others and of behaving in relation to food, often and above all involves being a "model user" of table service. We will analyze this aspect from the images and speeches posted on the Windsors' Twitter account, the official websites of the Royal Family and the manners manuals they sponsor. Each of these supports manifests an aspect of the subjectivity of the ideal guest as a model-user of…

Effets du bruit marin sur le changement des poissons sparidés juvéniles entre les espèces et les stades de développement
2023
International audience; Marine noise is an emerging pollutant inducing a variety of negative impacts on many animal taxa, including fish. Fish population persistence and dynamics rely on the supply of early life stages, which are often very sensitive to disturbance. Impacts of marine noise pollution (MNP) on juvenile fish have rarely been investigated in temperate regions. This is particularly true for the Mediterranean Sea, which is considered as an MNP hotspot due to intensive maritime traffic. In this study, we investigate the relationship between MNP related to boat traffic and (i) assemblage structure and (ii) the density of juvenile fishes (post-settlers at different stages) belonging…
