Metaphors and Emotions as Framing Strategies in Argumentation

The paper focuses on the role of both emotional and metaphorical processes in reasoning. The aim of the paper is to present an extension of the argumentative theory of reasoning proposed by Mercier and Sperber (2011). In order to advance an integrated model of the roles of metaphors and emotions in argumentation, the paper argues that it is possible to ascribe not only a negative role to emotions and metaphors, but also a positive one. Far from being just a source of fallacies in reasoning, indeed, both emotions and metaphors – considered as framing and reframing strategies – can play a constructive role in argumentation, by enhancing their creative power

Argomenti metaforici: come integrare persuasione e argomentazione

The persuasive power of metaphor is often seen in opposition to rational procedures in argumentation, which should guarantee deliberative democracy in the public sphere. Against this view, referable to the classic theory of argumentation, we adopt the argumentative theory of reasoning (MERCIER, SPERBER 2011) and present the results of an experimental study on the role of metaphors in a specific argumentative fallacy, the quaternio terminorum (ERVAS, LEDDA 2014; ERVAS, GOLA, LEDDA, SERGIOLI 2015). In light of the experimental evidence, we argue that (1) it is no longer possible to evaluate the role of metaphors in argumentation without distinguishing different kinds of metaphors (in the experimental study the distinction between dead and live metaphors is analysed); (2) it is possible to identify different argumentative styles (i.e. argumentative persuasion and reflective argumentation). Connecting different kinds of metaphors with different argumentative styles, we propose an interpretative framework able to integrate persuasion and argumentation

Argumentation as a Bridge Between Metaphor and Reasoning

UID/FIL/00183/2013 SFRH/BPD/115073/2016 WoS - record outside the portuguese subscription range.The aim of this chapter is to explore the relationship between metaphor and reasoning, by claiming that argumentation might act as a bridge between metaphor and reasoning. Firstly, the chapter introduces metaphor as a framing strategy through which some relevant properties of a (generally more concrete and known) source domain are selected to understand a (generally less concrete and known) target domain. The mapping of properties from the source to the target domain implicitly forces the interpreter to consider the target from a specific perspective. Secondly, the chapter presents metaphor as an implicit argument where some inferences can be drawn from the comparison between the source and the target domain. In particular, this chapter aims to understand whether and to what extent such an argument might be linked to analogical reasoning. The chapter argues that, in case of faulty analogy, this kind of argument might have the form of a quaternio terminorum, where metaphor is the middle term. Finally, the chapter presents the results of an experimental study, aiming to test the effect of the linguistic nature of the middle term on the detection of such faulty analogy. The chapter concludes that a wider context is needed to make sense of an analogical argument with novel metaphors, whilst in a narrow context, a lexicalised metaphor might be extended and the overall argument might be interpreted as metaphoric.authorsversionpublishe

Antiviral furanosesquiterpenes from Commiphora erythraea.

The crude methanolic extract obtained from C. erythraea resin was chromatographed on silica gel with solvent of increasing polarity. The extract and fractions were evaluated for cytotoxicity and antiviral activity [parainfluenza type 3 virus (PIV3)] by plaque forming units (PFU) reduction assay using HEp-2 cells (human larynx epidermoid carcinoma cell line). From the active fraction, five compounds were isolated and tested. Only two of these showed anti-PIV3 activity with a selectivity index (SI) of 66.6 and 17.5, respectively. Both the compounds are furanosesquiterpenoids

Object use affects motor planning in infant prehension

The purpose of this study was to investigate the factors underlying the ability to plan object-oriented grasping movements in the first two years of life. In particular, we were interested in evaluating the relationship between manual motor planning, object use and infant-parent interaction. In order to achieve this aim, grasping behaviors of nineteen healthy infants, aged nine to 25 months, were examined during naturalistic play sessions with a standard set of toys. Our main finding was that, regardless of age, infants perform a better manual planning when they use an object in a functional rather than non-functional way, suggesting that the planning of an action also depends on knowing the functional properties of an object. In addition, we found that the ability to use objects in a functional way was strongly affected by infant-parent interaction. Thus, level of object use and environmental role must be taken into account in order to understand the development of manual motor planning

Protective Activity of Broccoli Sprout Juice in a Human Intestinal Cell Model of Gut Inflammation

Benefits to health from a high consumption of fruits and vegetables are well established and have been attributed to bioactive secondary metabolites present in edible plants. However, the effects of specific health-related phytochemicals within a complex food matrix are difficult to assess. In an attempt to address this problem, we have used elicitation to improve the nutraceutical content of seedlings of Brassica oleracea grown under controlled conditions. Analysis, by LC-MS, of the glucosinolate, isothiocyanate and phenolic compound content of juices obtained from sprouts indicated that elicitation induces an enrichment of several phenolics, particularly of the anthocyanin fraction. To test the biological activity of basal and enriched juices we took advantage of a recently developed in vitro model of inflamed human intestinal epithelium. Both sprouts’ juices protected intestinal barrier integrity in Caco-2 cells exposed to tumor necrosis factor under marginal zinc deprivation, with the enriched juice showing higher protection. Multivariate regression analysis indicated that the extent of rescue from stress-induced epithelial dysfunction correlated with the composition in bioactive molecules of the juices and, in particular, with a group of phenolic compounds, including several anthocyanins, quercetin-3-Glc, cryptochlorogenic, neochlorogenic and cinnamic acids

Synergy between THESEUS and E-ELT

The Transient High Energy Sky and Early Universe Surveyor (THESEUS) is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-domain astrophysics. A fundamental contribution to achieve this goal will be provided by the powerful synergy between THESEUS and the extremely large ground-based telescopes which will operate in the next decade, like E-ELT. We discuss great improvements coming from this joint effort and describe some possible observing scenarios

GRB follow-up and science with THESEUS/IRT

The aim of the space mission concept THESEUS is to continue to collect and study the GRB events like Swift. It will allow us to study the early Universe. Moreover, it will offer us to study with unprecedented sensitivity GRB emission and to measure the redshift for the bursts with z>5. In this work, we investigate the advantages of a optical and near-infrared telescope mounted on the same satellite that is triggered by the GRB like THESEUS/IRT. Afterwards, we investigate the possible future developments in the GRB science, first for the prompt phase and the for afterglow phase. We find that more than half of the sources detected by THESEUS, and will never be visible from a a ground-based telescope. Moreover, only ∼50% of all observable sources are visible within one hour, i.e. <30% of all THESEUS transient sources. A higher number of observable sources can only be achieved with a network of telescopes. THESEUS will permit to detect the NIR prompt phase of the longest GRBs, increasing the number of events studied from gamma-rays to the near-infrared from a handful of events studied up to now to ≳10 GRBs per year
