Talking about something real: the concept of truth in multimodal non-fiction books for young people

2016

AbstractWithin social semiotics we discuss how different semiotic resources alone or in multimodal texts are used to communicate truth. This is one of the parts of the multimodal theory that are least developed and discussed. The discussion on truth within social semiotics is mainly focused on the relationship between a corresponding type of truth that is common in natural science and a more everyday perception of truth. This can give an incomplete and stereotypical image of how truth is portrayed. This essay attempts to nuance the picture by suggesting that our theoretical conceptions of how we portray truth visually can be nuanced and developed by combining the theory of multimodality wit…

Il filosofo non è il suo doppio: la scivolosa somiglianza tra filosofia e sofistica

2021

Heristics and rhetoric can therefore constitute a dangerous drift of the dialogical method; and despite some apparent similarities between the dialectical and the eristic method, what will always differentiate the philosopher from the erist is a radically different ethical horizon. If the philosopher is genuinely a friend of knowledge, wisdom and justice, and therefore every action of his is aimed at good, it will not be too difficult a task, as instead believes Deleuze, to think that his talks always transform the dispute into new acquisitions for knowledge

Valoración aristotélico-argumentativa del caso Iguala, a propósito de la Comisión por la Verdad y la Justicia

2022

En la presente investigación se analiza la fundamentación de la sentencia de amparo en revisión 203/2017 del Caso Iguala, en su resolución de conformar una comisión investigadora de la verdad y la justicia, para esclarecer y resolver el caso de los 43 desaparecidos. Desde la teoría aristotélica de la argumentación se busca estudiar la sentencia y decantar sus resultados lógico-argumentales a partir de dicho modelo hermenéutico. Finalmente, se evaluará su racionalidad de acuerdo con el paradigma tríadico: analítico-dialéctico-retórico que compone la lógica de Aristóteles, para ver si los argumentos presentados se justifican y convencen en sí mismos.                       

On Formalizing Logical Modalities

2021

This paper is in the scope of the philosophy of modal logic; more precisely, it concerns the semantics of modal logic, when the modal elements are interpreted as logical modalities. Most authors have thought that the logic for logical modality—that is, the one to be used to formalize the notion of logical truth (and other related notions)—is to be found among logical systems in which modalities are allowed to be iterated. This has raised the problem of the adequacy, to that formalization purpose, of some modal schemes, such as S4 and S5 . It has been argued that the acceptance of S5 leads to non-normal modal systems, in which the uniform substitution rule fails. The thesis supported in this…

Logics and operators

2003

Two connectives are of special interest in metalogical investigations — the connective of implication which is important due to its connections to the notion of inference, and the connective of equivalence. The latter connective expresses, in the material sense, the fact that two sentences have the same logical value while in the strict sense it expresses the fact that two sentences are interderivable on the basis of a given logic. The process of identification of equivalent sentences relative to theories of a logic C defines a class of abstract algebras. The members of the class are called Lindenbaum-Tarski algebras of the logic C. One may abstract from the origin of these algebras and exa…

This is my truth, tell me yours: some aspects of action research quality in the light of truth theories

2001

Abstract In this article the authors introduce some aspects of various truth theories in the context of action research. The traditional ways of determining quality are based on the correspondence theory of truth, which, in their view, conflicts with the basic assumptions of action research. The pragmatic theory of truth seems to be clearly represented in the world of action research. In their opinion, other theories of truth can be productively applied as well. In addition to the classical theories of truth – the correspondence theory, the coherence theory and the pragmatistic view on truth – they discuss the truth as ‘aletheia’ (a Heideggerian view on truth), as Habermasian consensus and …

Truthmaker Theory without Truthmakers

2013

Truthmaking without truthmakers (TWT, for short) is the thesis that although every true proposition is made true by reality, there need not be particular entities (like facts, states of affairs, or tropes) that make these propositions true. The first substantial part of this paper (section 2) is devoted to developing a particular version of TWT and at the same time defending TWT in general from arguments against it that have been advanced by orthodox truthmaker theorists. In the second part of the paper (section 3) I argue that talk about truthmakers within the theory can be understood as metaphoric and as conveying valuable information about something other than the supposed truthmakers: a…

Solid-Phase Synthesis of Peptide Libraries Combining α-Amino Acids with Inorganic and Organic Chromophores

2009

The synthesis of two series of peptidic chains composed of bis(terpyridine)ruthenium(II) acceptor units and organic chromophores (coumarin, naphthalene, anthracene, fluorene) by stepwise solid-phase peptide synthesis (SPPS) techniques is described. The first series of dyads comprises directly amide linked chromophores, while the second one possesses a glycine spacer between the two chromophores. All dyads were studied by UV/Vis and NMR spectroscopy, steady-state luminescence, luminescence decay and electrochemistry, as well as by DFT calculations. The results of these studies indicate weak electronic coupling of the chromophores in the ground state. Absorption spectra of all dyads are domin…

Structural characterization of a-plane Zn1−xCdxO (0 < x <0.085) thin films grown by metal-organic vapor phase epitaxy.

2006

Zn1−xCdxO(11math0) films have been grown on (01math2) sapphire (r–plane) substrates by metal-organic vapor phase epitaxy. A 800-nm-thick ZnO buffer, deposited prior to the alloy growth, helps to prevent the formation of pure CdO. A maximum uniform Cd incorporation of 8.5 at. % has been determined by Rutherford backscattering spectrometry. Higher Cd contents lead to the coexistence of Zn1−xCdxO alloys of different compositions within the same film. The near band-edge photoluminescence emission shifts gradually to lower energies as Cd is incorporated and reaches 2.93 eV for the highest Cd concentration (8.5 at. %). The lattice deformation, due to Cd incorporation, has been described using a n…
