    D7.1. Criteria for evaluation of resources, technology and integration.

    Get PDF
    This deliverable defines how evaluation is carried out at each integration cycle in the PANACEA project. As PANACEA aims at producing large scale resources, evaluation becomes a critical and challenging issue. Critical because it is important to assess the quality of the results that should be delivered to users. Challenging because we prospect rather new areas, and through a technical platform: some new methodologies will have to be explored or old ones to be adapted

    Modelling of ductile fracture in single point incremental forming using a modified GTN model

    Understanding the deformation and failure mechanisms in single point incremental forming (SPIF) is of great importance for achieving improved formability. Furthermore, there will be added benefits for more in depth evaluation of the effect of localised deformation to the fracture mechanism in SPIF. Although extensive research has been carried out in recent years, questions still remain on the shear and particularly its effect to the formability in SPIF processes. In this work, a modified Gurson–Tvergaard-Needleman (GTN) damage model was developed with the consideration of shear to predict ductile fracture in the SPIF process due to void nucleation and coalescence with results compared with original GTN model in SPIF. A combined approach of experimental testing and SPIF processing was used to validate finite element results of the shear modified Gurson–Tvergaard-Needleman damage model. The results showed that the shear modified GTN model improved the modelling accuracy of fracture over the original GTN model under shear loading conditions. Furthermore, the shear plays a role under meridional tensile stress to accelerate fracture propagation in SPIF processes

    Semantic distance predicts metaphoricity and creativity judgments in synesthetic metaphors

    This paper discusses a way of operationalizing metaphoricity quantitatively using a numerical measure of the semantic distance between two domains. We demonstrate the construct validity of this measure with respect to metaphoricity and creativity judgments in the domain of English synesthetic metaphors – expressions such as sweet melody and loud color that involve combinations of terms from conceptually distinct sensory modalities. In a pre-registered study, we find that a continuous measure of sensory modality difference predicts metaphoricity and creativity judgments. While our results use synesthetic metaphors as a test case, it is possible to extend the application of our measure of semantic distance to other metaphorical expressions. In addition to demonstrating the utility of this measure, this work also demonstrates the utility of rating data in the domain of metaphor research

    From Spanish <estar + gerund> to Italian <stare + gerund>. When teaching to unlearn is needed

    The Spanish periphrasis is formally similar to Italian but has a wider range of aspectual values (it can express durativity, in addition to progressivity) and is compatible with more tenses (perfectives, in addition to imperfectives). As an effect of transfer, L1Spanish learners of Italian often use to express durativity and combine it with perfective tenses, thus producing incorrect utterances like *Sono stato studiando. In this paper we report an acquisitional study which reveals that input exposure, intensity of L2 use, and non-focused instruction may not be sufficient to pre-empt the transfer and unlearn the erroneous uses of the periphrasis. Based on this result, we propose that a focused teaching intervention is needed. A small-scale pedagogical study based on a Cognitive Linguistics inspired teaching approach gives encouraging results. Die spanische Periphrase ist strukturell ähnlich wie die italienische Periphrase , bietet aber eine größere Bandbreite an Aspektfunktionen (sie kann neben Progressivität auch Dauer ausdrücken) und ist mit mehreren Zeitformen (zusätzlich zu imperfek-tiven auch perfektiven Zeitformen) kombinierbar. In diesem Artikel berichten wir über eine Fremd-spracherwerbstudie, die zeigt, dass die Input-Exposition, die Anwendungsintensität der L2 ohne die Anwendung von noticing Strategien möglicherweise nicht ausreichen, um der negative Transfer zu verhindern und die fehlerhafte Anwendung der Periphrase zu verlernen. Auf Basis dieses Ergebnisses wird eine Intervention vorgeschlagen, die auf den Einsatz von noticing Strategien setzt. Eine aus einem kleinem Sampling basierten didaktische Studie, die auf einen von der kognitiven Linguistik inspirierten Lehransatz gründet, liefert bereits vielversprechende Ergebnisse

    The Structure of Thoughts

    Get PDF
    In this paper I examine one well-known attempt to justify the claim that thoughts are intrinsically structured, Evans’s justification of the Generality Constraint. I compare this with a rival account, proposed by Peaocke. I end by suggesting that a naïve, Aristotelian realist has no difficulty at all in providing a justification of the Generality Constraint, which is therefore a view that deserves serious consideration

    Anti-Conceptualism and the Objects of Knowledge and Belief

    Get PDF
    Michael Ayers’s Knowing and Seeing: Groundwork for a New Empiricism is a rich and detailed development of two ideas. The first is that perception presents reality to us directly in a perspicuous way. We thus acquire primary knowledge of the world: “knowledge gained by being evidently, self-consciously, in direct cognitive contact with the object of the knowledge.” (Ayers 2019, 63) The second idea is that concepts are not needed in perception. In this article, the author examines Ayers’s view. The author proceeds as follows: In the first section, he identifies the target of Ayers’s attacks, conceptualism. He then describes why many philosophers have felt this conceptualist view to be attractive. In the next section, he discusses Ayers’s criticisms of conceptualism in an attempt to disentangle these criticisms from the statement of his positive view, which the author discusses in the following section. He ends by describing some problems for Ayers’s positive position that are, so he argues, the result of his vehement opposition to conceptualism
