Uttalet i läroböcker i svenska som andraspråk från begriplighetsperspektiv
2020
I denna artikel studerar jag hur uttal presenteras i finska gymnasieläroböcker (n=10) i svenska som andra språk. Syftet är att undersöka vilka uttalsdrag som tas upp i läroböckerna och relationen mellan dessa drag och begriplighet. Metoden som jag använder är kvalitativ innehållsanalys. Prosodiska drag har ansetts ha en stor betydelse för begriplighet. Vad det gäller svenska är speciellt satsrytm viktig. Analysen visar dock att uppmärksamheten oftast fästs vid enskilda segment (språkljud) och ord. Uttalet av hela satser övas också men regler eller anvisningar om produktionen av prosodiska drag presenteras bristfälligt. Att ange explicita råd och att göra inläraren medveten har i tidigare un…
La rigidité du cadre constitutionnel espagnol en ce qui concerne la répartition territoriale du pouvoir et le processus catalan de «déconnexion»
2016
Le processus démocratique que les institutions catalanes ont commencé avec l'intention de "déconnecter" de la réalité constitutionnelle et juridique espagnole, visant la création d'une République catalane, garde le cap après les élections régionales qui ont eu lieu en septembre 2015. Le renforcement du mouvement indépendantiste en Catalogne, au point d'être devenu presque majoritaire, ne peut être expliqué que par un défaut de fonctionnement du modèle constitutionnel espagnol de répartition territoriale du pouvoir. Ce modèle, créé par la Constitution espagnole de 1978, est le produit d'une conception rigide de la question « nationale » et de l'unité de l'Espagne. Après 2006, les événements …
Conseqüències psicològiques i socials del fenomen del desnonament: un estudi qualitatiu
2016
espanolEl desahucio plantea problemas en la salud fisica y mental de los individuos, ademas de aumentar las desigualdades sociales. El objetivo de este estudio es ayudar a los profesionales que intervienen en esta problematica social, explorando su percepcion en relacion con este tema. Se ha llevado a cabo un estudio cualitativo, exploratorio y descriptivo. Se han desarrollado 1 Focus Group y 9 entrevistas en profundidad a profesionales «claves», regidores y politicos de Servicios de la administracion publica, tecnicos y/o trabajadores sociales y mediadores de conflictos sociales. El desalojo se percibe como un proceso de duelo, con un impacto emocional severo que afecta a la salud de la pe…
Stress sensitivity of stylolite morphology
2009
International audience; Stylolites are rough surfaces that form by localized stress-induced dissolution. Using a set of limestone rock samples collected at different depths from a vertical section in Cirque de Navacelles (France), we study the influence of the lithostatic stress on the stylolites morphology on the basis of a recent morphogenesis model. We measured the roughness of a series of bedding-parallel stylolites and show that their morphology exhibits a scaling invariance with two self-affine scaling regimes separated by a crossover-length (L) at the millimeter scale consistent with previous studies. The importance of the present contribution is to estimate the stylolite formation s…
Predicted gamma-ray image of SN 1006 due to inverse Compton emission
2009
We propose a method to synthesize the inverse Compton (IC) gamma-ray image of a supernova remnant starting from the radio (or hard X-ray) map and using results of the spatially resolved X-ray spectral analysis. The method is successfully applied to SN 1006. We found that synthesized IC gamma-ray images of SN 1006 show morphology in nice agreement with that reported by the H.E.S.S. collaboration. The good correlation found between the observed very-high energy gamma-ray and X-ray/radio appearance can be considered as an evidence that the gamma-ray emission of SN 1006 observed by H.E.S.S. is leptonic in origin, though the hadronic origin may not be excluded.
Investigating the Structure of Vela X
2018
Vela X is the prototypical example of a pulsar wind nebula whose morphology and detailed structure have been affected by the interaction with the reverse shock of its host supernova remnant. The resulting complex of filamentary structure and mixed-in ejecta embedded in a nebula that is offset from the pulsar provides the best example we have of this middle-age state that characterizes a significant fraction of composite SNRs, and perhaps all of the large-diameter PWNe seen as TeV sources. Here we report on an XMM-Newton Large Project study of Vela X, supplemented by additional Chandra observations. Through broad spectral modeling as well as detailed spectral investigations of discrete emiss…
Emulation of Sun-Induced Fluorescence from Radiance Data Recorded by the HyPlant Airborne Imaging Spectrometer
2021
The retrieval of sun-induced fluorescence (SIF) from hyperspectral radiance data grew to maturity with research activities around the FLuorescence EXplorer satellite mission FLEX, yet full-spectrum estimation methods such as the spectral fitting method (SFM) are computationally expensive. To bypass this computational load, this work aims to approximate the SFM-based SIF retrieval by means of statistical learning, i.e., emulation. While emulators emerged as fast surrogate models of simulators, the accuracy-speedup trade-offs are still to be analyzed when the emulation concept is applied to experimental data. We evaluated the possibility of approximating the SFM-like SIF output directly based…
Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions
2020
Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.
Chimpanzees surviving in a fragmented high‐altitude forest landscape of the Congolese Albertine Rift
2021
This paper documents a community of eastern chimpanzees (Pan troglodytes schweinfurthii Giglioli, 1872) inhabiting three relict forest fragments situated on the Lake Albert escarpment, down the Ituri highlands, of eastern Democratic Republic of the Congo (DRC). The area explored had a combined forested surface of ±18.15 km2 in 2017, shrinking by 1.2% per year between 2010 and 2015. Between 2015 and 2017, we found 160 chimpanzee nests along 37.6 km of pilot walks, some up to 2,000 m altitude. Another 123 nests logged along 6.7 km transects led to an estimate of chimpanzee density of 4.62 weaned individuals per square kilometer of forest habitat. Camera‐trap images and direct observations rev…
Les responsables de résidences très sociales : des professionnels tiraillés entre différents cadres d’appréhension de la réalité
2022
Cet article porte sur les responsables de résidences très sociales, entendons des responsables de structures locatives destinées à des individus et familles très modestes qui ne sont pas intégrés dans le logement social « traditionnel ». Le propos souligne les tensions relatives au métier en dégageant plus précisément divers formats et cadres d’appréhension de la réalité dans lesquels les agents de terrain ici concernés sont engagés d’une façon ou d’une autre. Ce faisant, il s’agit d’identifier diverses formes de contrôle (gestionnaire, discrétionnaire, sécuritaire...) qui ponctuent les journées de professionnels à la fois proches et éloignés aussi bien de « leurs » résidents que de leur in…
