MODELLI, TESTI, PROCESSI: UNO STUDIO COGNITIVO DELLE METAFORE DELESSICALIZZATE E D’INVENZIONE

2014

La tesi di ricerca è basata sulle metafore delessicalizzate e d’invenzione riscontrate all’interno del romanzo di lingua tedesca «Kassandra» scritto nel 1983 dalla scrittrice Christa Wolf e all’interno del racconto di lingua tedesca «Minotaurus: eine Ballade» scritto nel 1985 Friedrich Dürrenmatt. Si vogliono analizzare i processi cognitivi che stanno alla base della creazione dei due tipi di metafore. Per farlo si è scelto di utilizzare tre teorie della linguistica cognitiva: la teoria della metafora concettuale (Lakoff e Johnson, 1980 e 1999); la teoria dell’integrazione concettuale (Turner e Fauconnier, 2002) e la teoria dell’analogia (Monneret, 2004). L’analisi ci permette di comprender…

PeerLA - Assistant for Individual Learning Goals and Self-Regulation Competency Improvement in Online Learning Scenarios

2016

While online learning is already a part of university education and didactics, not all students have the necessary self-regulation competency to really learn on their own efficiently and effectively. In classroom a teacher can take over a moderating part, set intermediate goals and give feedback to one's progress, but participants of online learning courses (e.g. in blended scenarios or Massive Open Online Courses (MOOCs)) face a higher demand of self-regulation competency. This paper presents a course and content independent assistant, PeerLA, which assists in improving self-regulation competency. PeerLA allows setting of long-term goals, breakdown into intermediate goals and keeps track o…

Blended learning: communication, locations and work-life practices

2011

The article discusses blended learning and how various delivery formats affect the way learning is situated in work-life practices. The authors approached this issue through an empirical study of an in-service training programme for middle-level managers in a number of case organisations. The programme used a combination of e-learning, textbooks and face-to-face seminars. The conclusion reached is that a purposeful blend of delivery modes and technology systems can situate learning outside the daily work location and at the same time facilitate the creation of communities of practice embedded in daily work experience. It is further argued that inflexibility can be a necessary for creation o…

Miscibility and properties of linear poly(l-lactide)/branched poly(l-lactide) copolyester blends

2006

Abstract Polymer blends consisting of linear poly( l -lactide) (PLLA) and different proportions of dendritic PLLA-based copolyesters ( hb -PLLA) characterized by different degrees of branching (DB) were obtained in melt. The solid-state properties of poly( l -lactide)s and their blends were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), atomic force microscopy (AFM) and stress–strain measurements. DSC and DMA methods proved miscibility of PLLA/ hb -PLLA blends for the studied composition range. AFM indicated that no phase separation occurs in PLLA/ hb -PLLA blends and that PLLA and hb -PLLA cocrystallize in one single lamellae type. The mechanica…

Designing biochar properties through the blending of biomass feedstock with metals: Impact on oxyanions adsorption behavior

2018

Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify biochar physico-chemical properties and its behavior as adsorbent. Six different compounds were used for metal-blending: AlCl3, Cu(OH)2, FeSO4, KCl, MgCl2 and Mg(OH)2. Pyrolysis experiments were performed at 400 and 700 °C and the characterization of biochar properties included: elemental composition, thermal stability, surface area and pore size distribution, Zeta potential, redox potential, chemical structure (with nuclear magnetic resonance) and adsorption behavior of arsenate, phosphate and nitrate. Metalblending strongly affected biochars' surface charge and redox potential. Moreover, it incre…

Towards a Blended Learning Model for Teaching and Learning Computer Programming: A Case Study

2008

Blended learning is becoming an attractive model in higher education as new innovative information technologies are becoming increasingly available. However, just blending face-to-face learning with information technologies cannot provide effective teaching and efficient solutions for learning. To be successful, blended learning must rely on solid learning theory and pedagogical strategies. In addition, there is a need for a design-based research approach to explore blending learning through successive cycles of experimentations, where the shortcomings of each cycle are identified, redesigned, and reevaluated. This paper reports on a study conducted on a blended learn- ing model in Java pro…

What is meant by hybridity? An investigation of hybridity and related terms in genre studies

2014

AbstractThis article is an investigation and a discussion of hybridity and related terms as used in linguistic studies of genre. The theoretical points that are made are illustrated with data from empirical research done by others and with the authors’ own data. The focus is on written texts but hybridity in spoken interaction is also discussed. The article defines the notion of genre and discusses (proto)typicality in relation to genre and hybridity. Recontextualization is also discussed. This is followed by a discussion of terms that have been used to talk about the processes of hybridity, firstly, as used in research that has mainly been done on spoken interaction. The focus then turns t…

Sex-pairing pheromones and reproductive isolation in three sympatric Cornitermes species (Isoptera, Termitidae, Syntermitinae)

2011

International audience; The species-specificity of pairing has been studied in three sympatric Neotropical termites: Cornitermes bequaerti, Cornitermes cumulans and Cornitermes silvestrii (Termitidae, Syntermitinae). Bioassays showed that sex attraction was highly species-specific between C. bequaerti and C cumulans but not between C. cumulans and C. silvestrii. The sex-pairing pheromone of the three species is secreted by the tergal glands of female alates. It consists of a common compound (3Z,6Z,8E)-dodeca-3,6,8-trien-1-ol. In C. bequaerti, this polyunsaturated alcohol is the only compound of the sex-pairing pheromone, whereas it is associated with the oxygenated sesquiterpene (E)-nerolid…
