Miten viittomakielen korpusta luodaan ja mihin sitä tarvitaan? Viittomakielten korpukset ja niiden tehtävät
2020
Artikkeli käsittelee suomalaisen ja suomenruotsalaisen viittomakielen korpusten luontia CFINSL-projektissa (Corpus project of Finland’s sign languages, Suomen viittomakielten korpusprojekti). Viittomakielillä ei ole kirjoitettua muotoa, joten korpusten laatiminen vaatii erilaista lähestymistä kuin korpusten luonti sellaisille puhutuille kielille, joilla on kirjoitettu muoto. Artikkelissa kuvataan ne menetelmät, joilla Jyväskylän yliopiston viittomakielen keskuksessa on koottu aineistoa suomalaisen ja suomenruotsalaisen viittomakielen korpukseen. Lisäksi kuvataan korpusaineiston teknistä käsittelyä, annotointia, metatietojen keruuta ja käsittelyä sekä aineiston säilytystä ja tutkijoiden käyt…
Volume strain, strain type and flow path in a narrow shear zone
1998
This study explores the state of finite strain and changes in the mean kinematic vorticity number, grain size, whole-rock chemistry and mineralogy across an upper amphibolite-facies shear zone in a metadiorite, northern Malawi, east-central Africa. P–T conditions during shear-zone formation and deformation were approximately 700–750 °C and 5–7 kbar and are slightly less than P–T conditions for the regional peak of metamorphism. The major rock-forming minerals, plagioclase, hornblende, biotite, and quartz, were deformed by crystal-plastic processes accompanied by, except for hornblende, dynamic recrystallization. The modal abundance of all four major rock-forming minerals shows no systematic…
Molecular Selectivity of CH 4 –C 2 H 6 Mixed Hydrates: A GCMC Study
2021
International audience; In this paper, we report the first grand canonical Monte Carlo simulation study aiming at characterizing the competitive trapping of CH4 and C2H6 molecules into clathrate hydrates under temperature conditions typical of those encountered at the surface of Titan. Various compositions of the fluid in contact with the clathrate phase have been considered in the simulations, including pure methane, pure ethane, and mixed fluids made of various methane/ethane ratios. The trapping isotherms obtained from the simulations clearly show that ethane molecules can be enclathrated at lower pressures than methane molecules. In addition, they provide evidence that the methane molec…
Numerical Simulations of a Flux Rope Ejection
2015
Coronal mass ejections (CMEs) are the most violent phenomena observed on the Sun. One of the most successful models to explain CMEs is the flux rope ejection model, where a magnetic flux rope is expelled from the solar corona after a long phase along which the flux rope stays in equilibrium while magnetic energy is being accumulated. However, still many questions are outstanding on the detailed mechanism of the ejection and observations continuously provide new data to interpret and put in the context. Currently, extreme ultraviolet (EUV) images from the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamic Observatory (SDO) are providing new insights into the early phase of CME evo…
The First Contact between the West and China: Sinology´s Origin
2019
In this study the first contact between Western and Asia culture, specifically with China, is reviewed. It begins with a reference to the Roman Empire mentioning the most relevant reference works for a more in-depth study. Next, it focuses on the diaspora of Nestorian Christianity towards the East and specifically its location in Chinese territory, considering also the main reference works and following a historical and lineal story. Then, the trips of Benjamín de Tudela, although they did not go beyond Mesopotamia and the Persian Gulf, served to verify the existence of Jewish communities in the Far East. In that frame of reference, the context of the Silk Road would explain its dedication …
A Brief Study of German Sinology Origins and the Dissemination of Daoism
2018
The dissemination of Daoism in the West is a process that, although it begins late and slow, will lead to the great interest that this way of thinking has finally awakened, not only in the academic field, but also in some popular media. In order to clarify the history of the Western study of Chinese doctrine, the present article reviews the contribution of what we call the German sinology until the mid-twentieth century to focus the contribution of the Germanic works. With the recognition that the first works in German language on the Daoism are due to the Austrian sinologist and Japanese scholar August Pfitzmaier, we review the history of sinology in Germany highlighting authors and summar…
Variables d'ajustament psicològic en una mostra d'adolescents amb mesures de protecció
2016
espanolEl presente trabajo tiene como objetivo determinar la salud psicologica de los adolescentes del sistema de proteccion, segun diferentes variables psicologicas, como autoconcepto, resiliencia, bienestar psicologico y capacidades y dificultades, en funcion del genero y de la toma o no de medidas de proteccion. Y, ademas, conocer las relaciones entre bienestar y las variables de ajuste, y determinar la capacidad predictiva de estas sobre el bienestar. La muestra esta formada por 44 adolescentes del sistema de proteccion y 48 adolescentes sin medidas de proteccion. Los resultados apuntan que los adolescentes con medidas de proteccion presentan una menor resiliencia, un peor bienestar psi…
StalAge – An algorithm designed for construction of speleothem age models
2011
Abstract Here we present a new algorithm ( StalAge ), which is designed to construct speleothem age models. The algorithm uses U-series ages and their corresponding age uncertainty for modelling and also includes stratigraphic information in order to further constrain and improve the age model. StalAge is applicable to problematic datasets that include outliers, age inversions, hiatuses and large changes in growth rate. Manual selection of potentially inaccurate ages prior to application is not required. StalAge can be applied by the general, non-expert user and has no adjustable free parameters. This offers the highest degree of reproducibility and comparability of speleothem records from …
Se professionnaliser dans un dispositif de formation spécialisée
2013
Les nouvelles modalités de scolarisation des élèves handicapés interrogent les enseignants dans l’exercice de leur métier, en particulier ceux qui sont confrontés aux inscrits dans les troubles importants des fonctions cognitives. Les dispositifs de formation et d’accompagnement aident à identifier les compétences constitutives d’une nouvelle identité professionnelle enseignante et contribuent à initier et à enrichir ce processus de transformation identitaire. L’analyse des regards portés par les enseignants inscrits en formation spécialisée par alternance permet de mieux cerner les conditions requises afin que les leviers de transformation des postures et des pratiques professionnelles se …
Qualification d’investissement et compétence en arbitrage international relatif aux investissements : la théorie du contrôle séparé devant le CIRDI
2014
La compétence d’un arbitre chargé d’appliquer le droit international des investissements exige l’existence préalable d’un investissement étranger. La présente étude analyse les difficultés du contrôle de l’existence de l’investissement devant le Centre international pour le règlement des différends relatifs aux investissements (CIRDI) et propose des moyens pour les surmonter. L’importance de la Convention de Washington du 18 mars 1965 explique l’attention particulière portée au CIRDI. En tenant compte des diverses approches proposées par la doctrine et la jurisprudence et de leurs fondements, la démarche suggérée par l’auteur est basée sur la dissociation des sources conventionnelles à l’or…
