The Expansion of English-medium Instruction in the Nordic Countries.Can Top-Down University Language Polices Encourage Bottom-up Disciplinary Literac…
2015
Recently, in the wake of the Bologna Declaration and similar internationalinitiatives, there has been a rapid increase in the number of university courses and programmestaught through the medium of English. Surveys have consistently shown theNordic countries to be at the forefront of this trend towards English-medium instruction(EMI). In this paper, we discuss the introduction of EMI in four Nordic countries (Denmark,Finland, Norway and Sweden). We present the educational setting and the EMIdebate in each of these countries and summarize relevant research findings. We then makesome tentative suggestions for the introduction of EMI in higher education in othercountries. In particular, we are…
Swarming : An Investigation Practice Supporting a Bottom-up Ecological Transition
2022
Dans cet article, nous rendons compte des pratiques d’essaimage d’initiatives locales de transition portées par des collectifs citoyens et associatifs en région Bourgogne Franche-Comté. L’essaimage, défini comme une façon d’enquêter pour agir, caractérise un « activisme environnemental du faire » qui se structure de manière réticulaire et translocale. Ces multiples initiatives qui font des gestes du quotidien un levier de transformation écologique s’activent avec ou sans les institutions territoriales. Celles-ci, indépendamment de l’écho qu’elles renvoient à ces expérimentations, sont interpellées dans leur manière de concevoir l’action publique sous contrainte écologique forte.
Does Top-Down Feedback Modulate the Encoding of Orthographic Representations During Visual-Word Recognition?
2016
Abstract. In masked priming lexical decision experiments, there is a matched-case identity advantage for nonwords, but not for words (e.g., ERTAR-ERTAR < ertar-ERTAR; ALTAR-ALTAR = altar-ALTAR). This dissociation has been interpreted in terms of feedback from higher levels of processing during orthographic encoding. Here, we examined whether a matched-case identity advantage also occurs for words when top-down feedback is minimized. We employed a task that taps prelexical orthographic processes: the masked prime same-different task. For “same” trials, results showed faster response times for targets when preceded by a briefly presented matched-case identity prime than when preceded by …
Bottom-up realization and electrical characterization of a graphene-based device.
2016
We propose a bottom-up procedure to fabricate an easy-to-engineer graphene-based device, consisting of a microstrip-like circuit where few-layer graphene nanoplatelets are used to contact two copper electrodes. The graphene nanoplatelets are obtained by the microwave irradiation of intercalated graphite, i.e., an environmentally friendly, fast and low-cost procedure. The contact is created by a bottom-up process, driven by the application of a DC electrical field in the gap between the electrodes, yielding the formation of a graphene carpet. The electrical resistance of the device has been measured as a function of the gap length and device temperature. The possible use of this device as a …
Rajallinen työmuisti S2-oppijoiden puheenymmärtämisvaikeuksien selittäjänä
2019
Tässä artikkelissa käsittelen työmuistin rajallisuuden ja aikuisten suomenoppijoiden puheenymmärtämisvaikeuksien yhteyttä tarkastelemalla oppijoiden kuuntelutehtäväsuorituksia ja niitä seuraavia stimulated recall -haastatteluja. Lisäksi selvitän, millaisilla muistitoiminnoilla oppijat kompensoivat työmuistin rajallisuutta ja helpottavat ymmärtämistä. Tutkimukseen osallistui 12 arabiankielistä alkeis- ja perustason aikuista suomenoppijaa, ja aineisto koostuu oppijoiden kuuntelutehtäväsuoritusten ja stimulated recall -haastattelujen videotallenteista. Työmuistin rajallisuuden vaikutus ymmärtämisvaikeuksissa tuli esiin erityisesti silloin, kun yhteen sanaan tai ilmaukseen keskittyminen aiheutt…
Bottom-up construction of dynamic density functional theories for inhomogeneous polymer systems from microscopic simulations
2020
We propose and compare different strategies to construct dynamic density functional theories (DDFTs) for inhomogeneous polymer systems close to equilibrium from microscopic simulation trajectories. We focus on the systematic construction of the mobility coefficient, $\Lambda(r,r')$, which relates the thermodynamic driving force on monomers at position $r'$ to the motion of monomers at position $r$. A first approach based on the Green-Kubo formalism turns out to be impractical because of a severe plateau problem. Instead, we propose to extract the mobility coefficient from an effective characteristic relaxation time of the single chain dynamic structure factor. To test our approach, we study…
Microfluidics and Macromolecules: Top-Down Analytics and Bottom-Up Engineering of Soft Matter at Small Scales
2016
Microfluidics is the art of creating and manipulating small portions of fluids. A typical variant of this art is fluid transport within small channels, either in form of laminar co-flow of miscible streams or in form of segmented-flow dripping and jetting of immiscible streams. Either method provides means to expose components of interest to defined local conditions such as spatially controlled concentration profiles that could not be established without the microfluidic auxiliaries. This ability renders microfluidics uniquely useful as both a method for advanced analytics and synthesis. This article sheds a spotlight on the use and utility of this method in macromolecular chemistry and phy…
Register affects language comprehension: ERP evidence from article omission in newspaper headlines
2011
Abstract Language processing involving syntax-discourse interface operations has been claimed to be particularly resource-consuming. In production, this additional complexity is claimed to be the source of article omission in the speech of young children and certain language-impaired speakers. In comprehension, article omission in some “special registers” (e.g., newspaper headlines) has been attributed to the trade-off between spending more processing resources and increasing processing speed. We investigated the comprehension of noun phrases (NPs) with and without articles (e.g., (a) policeman arrests (a) monk) when readers were or were not aware of reading headlines by recording electroph…
Oltre il dilemma monismo/dualismo: l’ontologia non riduzionista della coscienza nel naturalismo biologico di John Searle
2006
La relazione mira a testare la fecondità del modello naturalista ed antiriduzionista dell’ontologia della coscienza elaborato da John Searle alla luce della sua capacità di superare l’apparentemente inevitabile dilemma monismo/dualismo. La posizione searleana rivela la propria attendibilità nella sua capacità di superare le aporie concettuali alle quali sembrerebbero esporsi alcune tra le più avanzate proposte teoriche contemporanee sull’ontologia della coscienza, con riferimento in particolare alle proposte elaborate da Dennett e Chalmers in chiave rispettivamente eliminativista e dualista. Si analizza inoltre la proposta searleana in ordine alla sua capacità di proporre una soluzione conv…
