Vieraalla kielellä tapahtuvan sisäisen viestinnän vaikutukset organisaation tietovarantoon postmodernin tietokäsityksen viitekehyksessä

Tutkimus pohtii tiedon ja kielitaidon välistä suhdetta kansainvälisen organisaation sisäisessä viestinnässä. Työssä keskitytään erityisesti virallisen kielen vaihtamisen vaikutuksiin organisatorisentiedon laatuun ja määrään. Aihepiiriä lähestytään käsiteanalyyttisin keinoin. Työn on kvalitatiivinen ja siinä on käytetty kirjallista materiaalia, jonka kanssa tutkijalla ei ole ollut vuorovaikutuksessa. Tutkimustulokset osoittavat että on todennäköiseksi, jopa lähes varmaa, että organisaation virallisen kielen vaihtuminen muuttaa organisaation viestintärakennetta. En seurauksena kommunikaatiosuhteet eivät perustu enää osaamiseen tai viralliseen asemaan organisaatiossa. Uudet viestintäverkostot muodostuvat kielitaidon varaan jolloin väistämättä sivutetaan henkilöitä joilla olisi tietämystä, mutta ei kielitaitoa jakaa sitä organisaatiolle. Kansainvälistyminen tuo mukanaan laajemman potentiaalisentietovarannon, joka on mahdollista saada palvelemaan organisaatiota. Näiden kahden vastakkaisen seikan kokonaisvaikutus organisaation tietovarannolle kaipaa lisätutkimusta.

Els «criteris de visibilització de les dones» en català: límits sintacticosemàntics i discursius

L'objectiu d'aquest article és analitzar els principals criteris que les guies d'estil recomanen per visibilitzar les dones ¿o per fer un ús no sexista del llenguatge¿ des de dos punts de vista: el sintacticosemàntic i el discursiu. Des del punt de vista sintacticosemàntic, s'estudien bàsicament els fenòmens relacionats amb la coordinació, la concordança i la repetició o elisió d'elements (per exemple, especificadors del nom), i la manera com les diferents opcions afecten el significat oracional. Des del punt de vista discursiu, s'analitzen els fenòmens relacionats amb la coreferència; és a dir, la relació entre les diferents maneres d'expressar un mateix referent per mitjà d'elements nominals al llarg del text, i l'efecte que provoquen en el text en conjunt. Amb aquest objectiu, l'estudi analitza des d'un punt de vista qualitatiu les dades proporcionades per un corpus de textos procedents de tres àmbits (polític, administratiu i educatiu) en què s'apliquen sovint aquesta mena de criteris. Paraules clau: català, llenguatge no sexista, visibilització lingüística de les dones, sintaxi, cohesió, coreferència, llenguatge androcèntric, estil. The goal of this article is to analyse the main criteria recommended by style guides aimed at making women more visible or, in other words, to make a non-sexist use of language. I will concentrate on two main aspects: the syntactic-semantic and the discursive. From a syntactic-semantic point of view, the main elements being studied are those related to coordination, agreement and repetition or omission of elements (for instance, noun specifiers), and also the way the different options chosen affect the meaning of the sentence. From a discursive and stylistic point of view, the elements analysed are those related to coreference, that is, the relationship between the different ways of expressing a same referent through different elements in the text, and the effect they produce in the text as a whole. Having this as the main goal, the study analyses from a qualitative point of view the data from a corpus in three different areas (politics, administration and education), which often apply this kind of criteria. Keywords: Catalan, non-sexist language, female linguistic visibility, syntax, cohesion, co-reference, androcentric language, style

Les croyances des enseignants et leurs pratiques relativement à l’évaluation de l’oral : étude de cas de deux enseignants de français de 3e secondaire

Depuis quelques années, plusieurs didacticiens du français se penchent sur l’enseignement et l’évaluation de l’oral, mais peu d’informations sont encore disponibles concernant les pratiques effectives des enseignants à cet égard. Notre recherche vise à décrire les croyances de deux enseignants de français au secondaire et leurs pratiques au sujet de l’évaluation de l’oral, plus particulièrement de l’oral dans une situation d’interaction entre pairs. Une entrevue dirigée a permis d’avoir accès à leurs croyances et à leurs pratiques déclarées, alors que le think-aloud a été employé pour observer leur pratique d’évaluation, à l’étape du jugement, d’une situation d’interaction entre pairs. Nos résultats montrent que, du point de vue de leurs croyances, les enseignants ont tous deux des préoccupations concernant les tâches et les instruments d’évaluation, et que leurs pratiques d’évaluation déclarées sont assez semblables en ce qui a trait aux tâches retenues, à leur fréquence et à l’intention poursuivie. Du côté de leurs pratiques d’évaluation observées à l’étape du jugement, nous exposons de façon détaillée les gestes d’enseignants en situation authentique, en identifiant les principaux processus cognitifs et métacognitifs impliqués dans cette tâche complexe. Des divergences entre les deux enseignants ont été observées relativement à leurs croyances, pratiques déclarées et pratiques observées durant le jugement. Tout d’abord, les critères retenus pour l’évaluation (pratique déclarée) ne tiennent pas toujours compte de ce qu’ils croient important d’enseigner en classe (croyance). De plus, malgré une pratique déclarée positive concernant l’autoévaluation, ces enseignants n’y ont peu ou pas eu recours durant leur jugement. Enfin, les gestes de l’un, durant le jugement, tendaient vers la posture d’instructeur-contrôleur, alors que ceux de l’autre s’inscrivaient davantage dans la posture de conseiller-didacticien. De façon générale, nous constatons que les pratiques de ces enseignants sont plus influencées par les situations rencontrées en tant qu’élèves et les traditions d’enseignement de la discipline que par le programme en vigueur.

Studies on a syntax based approach for translation between structurally different languages and the development of a prototype for Malayalam to English translation

This thesis summarizes the results on the studies on a syntax based approach for translation between Malayalam, one of Dravidian languages and English and also on the development of the major modules in building a prototype machine translation system from Malayalam to English. The development of the system is a pioneering effort in Malayalam language unattempted by previous researchers. The computational models chosen for the system is first of its kind for Malayalam language. An in depth study has been carried out in the design of the computational models and data structures needed for different modules: morphological analyzer , a parser, a syntactic structure transfer module and target language sentence generator required for the prototype system. The generation of list of part of speech tags, chunk tags and the hierarchical dependencies among the chunks required for the translation process also has been done. In the development process, the major goals are: (a) accuracy of translation (b) speed and (c) space. Accuracy-wise, smart tools for handling transfer grammar and translation standards including equivalent words, expressions, phrases and styles in the target language are to be developed. The grammar should be optimized with a view to obtaining a single correct parse and hence a single translated output. Speed-wise, innovative use of corpus analysis, efficient parsing algorithm, design of efficient Data Structure and run-time frequency-based rearrangement of the grammar which substantially reduces the parsing and generation time are required. The space requirement also has to be minimised

Foco oracional y polaridad: en torno a una asimetría entre el español y el catalán

En aquest estudi s’examina la perifèria esquerra del català antic en comparació amb la del castellà antic, i es descriuen les diferències més rellevants

Ordre de mots i estructura informativa a la llengua de Francesc Eiximenis

En aquest estudi s’examina la llengua d’alguns textos de Francesc Eiximenis (concretament, el ‘Dotzè del Crestià’ i les cartes autògrafes publicades per Martí 2002) per tal d’aprofundir en la distribució de l’estructura informativa i el consegüent ordre de mots que utilitza l’autor. L’objectiu d’aquesta comunicació és aprofundir en els casos d’ avantposició del català antic que correspon a una estructura de focalització feble (no contrastiva)

Modernitat i canvi de llengua. El pas del castellà al català a l'obra de Pere Gimferrer (aspectes crítics, teòrics i lexicomètrics)

L’objecte d’aquesta tesi es l’estudi del canvi de llengua que es produeix en l’obra poètica de Pere Gimferrer. Per arribar-hi haurem d’activar un itinerari complex – crític, teòric i metodològic -. La problemàtica que presentem intenta resoldre una qüestió central: tractar d’elucidar si aquest canvi de llengua – del castellà al català, i més tard, del català al castellà – implica necessàriament un canvi d’estil, o si, en canvi, l’estil de poeta resta estable tot i haver canviat la llengua d’escriptura. Si la recerca està orientada a trobar una possible resposta a aquesta qüestió, nosaltres ens proposem com a punt de partida l’anàlisi de les conseqüències que comporta l’escriure en diferents llengües a la modernitat. Per aquesta raó, en la tesi es desenvolupen teòricament les nocions de “frontera”, “extraterritorialitat”, o “llengua estrangera” que ens seran útils per a portar a terme la nostra anàlisi. A la darrera part, a través de la lexicometria, presentem un apropament exhaustiu a les particularitats lèxiques i sintagmàtiques de l’obra de Pere Gimferrer. Finalment, proposem una resposta a la problemàtica proposada.

Statistical downscaling of river flows

An extensive statistical ‘downscaling’ study is done to relate large-scale climate information from a general circulation model (GCM) to local-scale river flows in SW France for 51 gauging stations ranging from nival (snow-dominated) to pluvial (rainfall-dominated) river-systems. This study helps to select the appropriate statistical method at a given spatial and temporal scale to downscale hydrology for future climate change impact assessment of hydrological resources. The four proposed statistical downscaling models use large-scale predictors (derived from climate model outputs or reanalysis data) that characterize precipitation and evaporation processes in the hydrological cycle to estimate summary flow statistics. The four statistical models used are generalized linear (GLM) and additive (GAM) models, aggregated boosted trees (ABT) and multi-layer perceptron neural networks (ANN). These four models were each applied at two different spatial scales, namely at that of a single flow-gauging station (local downscaling) and that of a group of flow-gauging stations having the same hydrological behaviour (regional downscaling). For each statistical model and each spatial resolution, three temporal resolutions were considered, namely the daily mean flows, the summary statistics of fortnightly flows and a daily ‘integrated approach’. The results show that flow sensitivity to atmospheric factors is significantly different between nival and pluvial hydrological systems which are mainly influenced, respectively, by shortwave solar radiations and atmospheric temperature. The non-linear models (i.e. GAM, ABT and ANN) performed better than the linear GLM when simulating fortnightly flow percentiles. The aggregated boosted trees method showed higher and less variable R2 values to downscale the hydrological variability in both nival and pluvial regimes. Based on GCM cnrm-cm3 and scenarios A2 and A1B, future relative changes of fortnightly median flows were projected based on the regional downscaling approach. The results suggest a global decrease of flow in both pluvial and nival regimes, especially in spring, summer and autumn, whatever the considered scenario. The discussion considers the performance of each statistical method for downscaling flow at different spatial and temporal scales as well as the relationship between atmospheric processes and flow variability.

Changing Standards? Children's awareness and knowledge of features of written standard English at ages 10-11

This paper reports the findings of a small-scale research project, which investigated the levels of awareness and knowledge of written standard English of 10- and 11-year-old children in two English primary schools over a six-year period, coinciding with the implementation in the schools of the National Literacy Strategy (NLS). A questionnaire was used to provide quantitative and qualitative data relating to: features of writing which were recognised as standard or non-standard; children's understanding of technical terminology; variations between boys' and girls' performance; and the impact of the NLS over time. The findings reveal variations in levels of recognition of different non-standard features, differences between girls' and boys' recognition, possible examples of language change, but no evidence of a positive impact of the NLS. The implications of these findings are discussed both in terms of changes in educational standards and changes to standard English.

Verb retrieval in fluent aphasia: a clinical study

Background: Problems with lexical retrieval are common across all types of aphasia but certain word classes are thought to be more vulnerable in some aphasia types. Traditionally, verb retrieval problems have been considered characteristic of non-fluent aphasias but there is growing evidence that verb retrieval problems are also found in fluent aphasia. As verbs are retrieved from the mental lexicon with syntactic as well as phonological and semantic information, it is speculated that an improvement in verb retrieval should enhance communicative abilities in this population as in others. We report on an investigation into the effectiveness of verb treatment for three individuals with fluent aphasia. Methods & Procedures: Multiple pre-treatment baselines were established over 3 months in order to monitor language change before treatment. The three participants then received twice-weekly verb treatment over approximately 4 months. All pre-treatment assessments were administered immediately after treatment and 3 months post-treatment. Outcome & Results: Scores fluctuated in the pre-treatment period. Following treatment, there was a significant improvement in verb retrieval for two of the three participants on the treated items. The increase in scores for the third participant was statistically nonsignificant but post-treatment scores moved from below the normal range to within the normal range. All participants were significantly quicker in the verb retrieval task following treatment. There was an increase in well-formed sentences in the sentence construction test and in some samples of connected speech. Conclusions: Repeated systematic treatment can produce a significant improvement in verb retrieval of practised items and generalise to unpractised items for some participants. An increase in well-formed sentences is seen for some speakers. The theoretical and clinical implications of the results are discussed.

The impact of stratospheric ozone recovery on the Southern Hemisphere westerly jet

In the past several decades, the tropospheric westerly winds in the Southern Hemisphere have been observed to accelerate on the poleward side of the surface wind maximum. This has been attributed to the combined anthropogenic effects of increasing greenhouse gases and decreasing stratospheric ozone and is predicted to continue by the Intergovernmental Panel on Climate Change/Fourth Assessment Report (IPCC/AR4) models. In this paper, the predictions of the Chemistry-Climate Model Validation (CCMVal) models are examined: Unlike the AR4 models, the CCMVal models have a fully interactive stratospheric chemistry. Owing to the expected disappearance of the ozone hole in the first half of the 21st century, the CCMVal models predict that the tropospheric westerlies in Southern Hemisphere summer will be decelerated, on the poleward side, in contrast with the prediction of most IPCC/AR4 models.

Mechanisms linking volcanic aerosols to the Atlantic meridional overturning circulation

This study examines the sensitivity of the climate system to volcanic aerosol forcing in the third climate configuration of the Met Office Unified Model (HadCM3). The main test case was based on the 1880s when there were several volcanic eruptions, the well-known Krakatau being the largest. These eruptions increased atmospheric aerosol concentrations and induced a period of global cooling surface temperatures. In this study, an ensemble of HadCM3 has been integrated with the standard set of radiative forcings and aerosols from the Intergovernmental Panel on Climate Change Fourth Assessment Report simulations, from 1860 to present. A second ensemble removes the volcanic aerosols from 1880 to 1899. The all-forcings ensemble shows an attributable 1.2-Sv (1 Sv ≡ 106 m3 s−1) increase in the Atlantic meridional overturning circulation (AMOC) at 45°N—with a 0.04-PW increase in meridional heat transport at 40°N and increased northern Atlantic SSTs—starting around 1894, approximately 11 years after the first eruption, and lasting a further 10 years at least. The mechanisms responsible are traced to the Arctic, with suppression of the global water cycle (high-latitude precipitation), which leads to an increase in upper-level Arctic and Greenland Sea salinities. This then leads to increased convection in the Greenland–Iceland–Norwegian (GIN) Seas, enhanced Denmark Strait overflows, and AMOC changes with density anomalies traceable southward along the western Atlantic boundary. The authors investigate whether a similar response to the Pinatubo eruption in 1991 could still be ongoing, but do not find strong evidence.
