The Effects of Multiple‐Exposure Textual Enhancement on Child L2 Learners’ Development in Derivational Morphology: A Multi‐Site Study
2021
Use of contrastive syllabic information in L1-L2map for Spanish pronunciation teaching
2018
En la adquisición del sistema fónico de una segunda lengua (L2) al aprendiz no le basta con familiarizarse con los nuevos sonidos nuevos de la L2, sino que debe interiorizar las pautas distribucionales de los segmentos y las restricciones silábicas propias de la L2. El objetivo de este trabajo es, por un lado, reflexionar sobre los factores lingüísticos y contrastivos que pueden influir en la adquisición de las restricciones silábicas del español como lengua extranjera y, por otro lado, presentar las nuevas funciones de la base de datos multilingüe L1-L2map que permiten, precisamente, realizar análisis contrastivos de la estructura silábica de una lengua nativa (L1) y una L2. A lo largo del…
Digging up the frequency of phrasal verbs in English for the Police: the case of up
2016
The present study focuses on the frequency of phrasal verbs with the particle up in the context of crime and police investigative work. This research emerges from the need to enlarge McCarthy and O’Dell’s (2004) scope from purely criminal behavior to police investigative actions. To do so, we relied on a corpus of 504,124 running words made up of spoken dialogues extracted from the script of the American TV series Castle shown on ABC since 2009. Based on Rudzka-Ostyn’s (2003) cognitive motivations for the particle up, we have identified five different meaning extensions for our phrasal verbs. Drawing from these findings, we have designed pedagogical activities for those L2 learners that stu…
Geometric rough paths on infinite dimensional spaces
2022
Similar to ordinary differential equations, rough paths and rough differential equations can be formulated in a Banach space setting. For $\alpha\in (1/3,1/2)$, we give criteria for when we can approximate Banach space-valued weakly geometric $\alpha$-rough paths by signatures of curves of bounded variation, given some tuning of the H\"older parameter. We show that these criteria are satisfied for weakly geometric rough paths on Hilbert spaces. As an application, we obtain Wong-Zakai type result for function space valued martingales using the notion of (unbounded) rough drivers.
Rough McKean-Vlasov dynamics for robust ensemble Kalman filtering
2021
Motivated by the challenge of incorporating data into misspecified and multiscale dynamical models, we study a McKean-Vlasov equation that contains the data stream as a common driving rough path. This setting allows us to prove well-posedness as well as continuity with respect to the driver in an appropriate rough-path topology. The latter property is key in our subsequent development of a robust data assimilation methodology: We establish propagation of chaos for the associated interacting particle system, which in turn is suggestive of a numerical scheme that can be viewed as an extension of the ensemble Kalman filter to a rough-path framework. Finally, we discuss a data-driven method bas…
Evaluación del componente gramatical en el enfoque comunicativo por tareas en la enseñanza de Español como Lengua Extranjera
2014
Entre una de las últimas tendencias en la enseñanza de lenguas encontramos el enfoque comunicativo, en él se pretende que el alumnado adquiera nuevos conocimientos de una lengua extranjera (L2) utilizando principalmente la comunicación (tanto oral como escrita). Nosotros vamos a estudiar el enfoque comunicativo mediante tareas, es decir, aquél en el que se plantea una tarea final, al término de la unidad didáctica. Las actividades que se proponen a lo largo de la unidad están dirigidas a facilitar al estudiantado la resolución de dicha tarea final, por lo tanto son tareas posibilitadoras. TEMA Resulta problemático trabajar la gramática dentro de la enseñanza de E/LE, ya que según el método …
L’acquisizione delle categorie morfologiche in apprendenti adulti analfabeti o bassamente scolarizzati: un’indagine sperimentale.
2016
L’incremento dei flussi immigratori verso l’Europa ha da qualche anno riportato alla ribalta il tema dell’analfabetismo. Molte realtà (tra queste, alcune universitarie) impegnate nella didattica dell’italiano a stranieri sono chiamate a raccogliere la sfida posta dalla presenza di apprendenti adulti analfabeti (in lingua madre) o bassamente scolarizzati. L’alfabetizzazione di apprendenti scarsamente scolarizzati costituisce un nuovo campo d’intervento didattico, che ha alle spalle un orizzonte teorico piuttosto consistente (cfr. LESLLA). La ricerca acquisizionale suggerisce non solo che le abilità orali e di scrittura si condizionano vicendevolmente (per esempio, le capacità astrattive conn…
The development of L2 Italian morphosyntax in adult learners with limited literacy
2020
Low literacy and schooling rates are a significant factor among adults in the recent migration towards Europe, including Italy. However, in Italy linguistic research has paid very little attention to the relationship between newcomers’ language learning processes and (low) schooling and literacy. This lack of attention to the role of home language(s) literacy – and, more in general, to the sociolinguistic variables characterising the condition of migration – is problematic at a theoretical level. As it assumes the role of literacy as the main research question, the investigation on the acquisition of morphosyntax by adult learners with limited literacy, which is described in the volume, rep…
Hormone therapy is associated with better body composition and adipokine/glucose profiles
2012
Objective: The aim of this study was to evaluate the possibility of preventing the metabolic health consequences of postmenopausal hypogonadism with the use of long-term hormone therapy (HT). Methods: We used a monozygotic co-twin control design including 10 twin pairs (aged 56-62 y) discordant for HT (duration of HT, 2-10 y). In addition, 14 premenopausal women (aged 29-35 y) who did not use HT were studied to evaluate the differences in metabolic health between the premenopausal and postmenopausal states. Body composition was determined, and waist-to-hip ratio was used as an estimate for fat distribution. Serum sex steroids, sex hormone-binding globulin, and serum lipid and glucose profil…
CD40 activation in human pancreatic islets and ductal cells.
2008
Aims/hypothesis: CD40 expression on non-haematopoietic cells is linked to inflammation. We previously reported that CD40 is expressed on isolated human and non-human primate islets and its activation results in secretion of IL-8, macrophage inflammatory protein 1-beta (MIP-1β) and monocyte chemoattractant protein-1 (MCP-1) through nuclear factor-κB and extracellularly regulated kinases 1/2 pathways. The objective of this study was to identify the pattern of gene expression, and to study viability and functionality affected by CD40-CD40 ligand (CD40L) interaction in human islets. Furthermore, we have studied the CD40-mediated cytokine/chemokine profile in pancreatic ductal cells, as they are…
