Valodas elementu lietojuma variācijas Anglijas un Skotijas dienas laikrakstu tekstos
2019
Laikraksti ir pastāvējuši jau gadsimtiem ilgi un vēsturiski tie ir attīstījuši dažādus veidus, kas attiecināmi uz laikrakstu izmēru, mērķauditoriju, aprakstītajiem notikumiem; tomēr visiem laikrakstiem ir noteikti struktūras un satura pamatprincipi, pēc kuriem tie vadās, lai saglabātu rakstīta teksta tipiskās pazīmes visā pasaulē. Šī darba mērķis ir izpētīt valodas lietojuma variācijas dienas laikrakstu tekstos, kas parādītu, kā atšķiras tematiski atbilstošās nodaļas un valodas reģistra variācijas dažādu tipu laikrakstos dažādos publicēšanas apgabalos. Metodes: Trīs britu un skotu laikraksti ar plašāko lasītāju publiku tika izvēlēti, lai tajos noteiktu leksisko blīvumu un dažādību divās tem…
Effects of agricultural drainage systems on sediment connectivity in a small Mediterranean lowland catchment
2018
Traditional drainage systems combining man-made channels and subsurface tile drains have been used since Roman times to control water excess in Mediterranean lowland regions, favouring adequate soil water regime for agriculture purposes. However, mechanization of agriculture, abandonment or land use changes lead to a progressive deterioration of these drains in the last decades. The effects of these structures on hydrological and sediment dynamics have been previously analyzed in a small Mediterranean lowland catchment (Can Revull, Mallorca, Spain, 1.4 km2) by establishing an integrated sediment budget with a multi-technique approach. Moreover, the recent advances in morphometric techniques…
Modelo de cabalgamiento profundo para el Alto Atlas (Marruecos). Implicaciones sísmicas en la zona de colisión entre Eurasia y Africa
2007
Previous crustal models of the High Atlas suppose the existence of a mid-crustal detachment where all the surface thrusts merged and below which the lower crust was continuous. However, both seismic refraction data and gravity modeling detected a jump in crustal thickness between the High Atlas and the northern plains. Here we show that this rapid and vertical jump in the depth of Moho discontinuity suggests that a thrust fault may penetrate the lower crust and offset the Moho (deep-rooted “thick skinned” model). The distribution of Neogene and Quaternary volcanisms along and at the northern part of the High Atlas lineament can be related to the beginning of a partial continental subduction…
A Linear Programming Method for Bounding Plastic Deformations
1988
A method for providing upper and lower bounds to plastic deformations is presented, which has the feature of being applicable both below and above the structure shakedown limit. The bounds provided are expressed in terms of some fictitious plastic strains obeying relaxed yielding laws, whose evaluation is made by means of a suitable LP-based algorithm.
Subglacial bedforms of the Zemgale Ice Lobe, south-eastern Baltic
2015
Abstract Presented in this paper are the results of the mapping of ∼6600 subglacial bedforms of the Zemgale Ice Lobe (ZIL), their composition and internal structure in the south-eastern Baltic region. Topographic maps at scale 1:10,000 were mainly used to map bedforms in Latvia, while a digital elevation model with cell size of 5 m was used for North Central Lithuania. The ZIL operated during the deglaciation of the Late Weichselian Scandinavian Ice Sheet (SIS), at least in the Middle Lithuanian and North Lithuanian glacial phases, and created a subglacial landform assemblage consisting of glacial lineations such as drumlins, mega-flutings, Mega Scale Glacial Lineations (MSGLs) and transver…
Constraints on ontology changing complexation processes: Evidence from event-related brain potentials
2010
This paper investigates complex anaphoric reference (i.e., when an anaphor refers to a propositionally structured referent). Complex anaphors (e.g., this process, this event) differ in their ontological feature setup, and the ontological type assigned to a referent can change due to the lexical meaning of the complex anaphor. Previous research has proposed that such changes have to comply with an ontological ‘abstractness constraint’ restricting the direction of ontological change. We present an event-related potential study that provides evidence that violations of the abstractness constraint result in processing costs. The data reveal that violating this constraint by shifting the referen…
Modeling Listeners’ Emotional Response to Music
2012
An overview of the computational prediction of emotional responses to music is presented. Communication of emotions by music has received a great deal of attention during the last years and a large number of empirical studies have described the role of individual features (tempo, mode, articulation, timbre) in predicting the emotions suggested or invoked by the music. However, unlike the present work, relatively few studies have attempted to model continua of expressed emotions using a variety of musical features from audio-based representations in a correlation design. The construction of the computational model is divided into four separate phases, with a different focus for evaluation. T…
El aprendizaje de los rasgos fonopragmáticos del enfado en español como lengua extranjera
2020
espanolIdentificar la expresion de enfado en una lengua extranjera y reproducirla con adecuacion y precision son destrezas cuya relevancia y falta de propuestas satisfactorias han sido senaladas por las investigaciones sobre la ensenanza de emociones (Dewaele, 2010; Toya & Kodis, 1996). Este trabajo combina la identificacion de carencias en la didactica de la entonacion emocional con el analisis de muestras espontaneas de enfado como base de unas pautas didacticas para introducir la ensenanza contextualizada de la expresion de enfado en espanol. A traves de muestras de un corpus coloquial, se identifican los rasgos caracteristicos de la expresion de enfado en espanol. Una seleccion de rasgo…
Semantic Models and Translating
1994
Abstract: This paper examines the relevance of three semantic models for translation. Structural semantics, more specifically semantic feature analysis, has given rise to the maxim that we should translate "bundles of semantic features". Prototype semantics suggests that word-meanings have cores and fuzzy edges which are influenced by culture. For translation this means that we do not necessarily translate bundles of features but have to decide whether to focus on the core or the fuzzy edges of the meaning of a particular word. Scenes-and-frames semantics suggests that word meaning is influenced by context and the situation we are in. Word-meaning is thus not static but dynamic, and it is t…
Les eines computacionals i el disseny de corpus orals: un diàleg vigent
2020
The design of an oral corpus and the processes of registering, codifying and treating the materials in order to build a useful resource for linguistic analysis prompt numerous decisions regarding theory and methodology. This article is focused on those stages of corpus construction which are more clearly conditioned by the computational processing necessary to make it functional. In order to adequately match the initial expectations and the real possibilities of using the tool, each feature we intend to codify must be measured against the workload and the means required to do so. Therefore, it is essential to take into account the available possibilities of processing and exploitation as th…
