Jürgen Habermas i Michel Foucault : dues concepcions de racionalitat

Aquest treball vol mostrar que el debat de la raó il·lustrada, ja sigui des d'una posició de relativa defensa (com la que pren l'alemany Jürgen Habermas) o des d'una posició més crítica (personalitzada en aquest cas pel filòsof francès Michel Foucault), encara avui, al començament del segle XXI, determina plenament el debat sobre la racionalitat humana en general. El treball s'emmarca dins l'àmbit de la filosofia contemporània, més concretament dins la problemàtica filosòfica entorn de la raó que es va plantejar amb l'adveniment de la Modernitat, després amb l'anomenada Postmodernitat i actualment amb el corrent del Pensament Únic.

El cuerpo-especie y la nuda vida. Un estudio comparativo entre Michel Foucault y Giorgio Agamben

Michel Foucault hace pública por primera vez su tesis sobre el biopoder en 1975 y muere en 1984 con tan sólo cincuenta y ocho años, razón por la cual podemos considerar que sus ideas quizá hubieran podido desarrollarse más de haber vivido más tiempo.

Symbolic meaning of local identity – A case study on Barcelona place brand representation

The core objective of this research process was to design an operational tool for place brand analysis. By modelling the emotional significance and the deeper-lying symbols associated to a specific place identity I expected to create a semiotic tool that could be applied, mutatis mutandis, on other similar place brands. As a field case study to develop the instrument, my choice of the research arena was Barcelona city, the capital of Catalonia Autonomous Community, Spain. Barcelona brand identity was approached in the line of the Chicago Urban Anthropology School. The research methods were designed according to the prescriptions of the urban anthropology, namely qualitative methods: in-depth interviews and discourse analysis. The final research outcome was a model summarizing a range of specific emotional values that support a place brand to position in the collective mindset and to assume a positively valued status and identity in the world order.

Athermal character of structural phase transitions

The significance of thermal fluctuations in nucleation in structural first-order phase transitions has been examined. The prototypical case of martensitic transitions has been experimentally investigated by means of acoustic emission techniques. We propose a model based on the mean first-passage time to account for the experimental observations. Our study provides a unified framework to establish the conditions for isothermal and athermal transitions to be observed.

Algunas reflexiones críticas sobre la lectura de Michel Foucault del Erótico (Amatorius) de Plutarco

El objetivo de este artículo es reflexionar sobre la lectura de M. Foucault del Erótico de Plutarco en su Histoire de la sexualité, poniendo especial énfasis en el hecho de que, en contra de lo que afirma el pensador francés, el centro del debate no es, en opinión del autor, el tema del verdadero placer, el obtenido por el erastés de su erómenos o el obtenido por el marido de su mujer, sino la necesidad de atribuir también eros y amistad (éros kaì philia) al amor matrimonial.

Algunes reflexions crítiques al voltant de la lectura de Michel Foucault de L'Eròtic (Amatorius) de Plutarc

L'objectiu d'aquest article és fer una reflexió crítica de la lectura de M. Fouccault de l'Eròtic de Plutarc en la seva Histoire de la sexualité, posant especial èmfasi en el fet que, en contra del que afirma el pensador francès, el centre del debat no és, en opinió de l'autor, el tema del veritable plaer, l'obtingut per l'erastés del seu erómenos o l'obtingut pel marit de la muller, sinó la necessitat d'atribuir també éros i amistat (éros kaì philia) a l'amor matrimonial.

Some critical reflections on Michel Foucault's reading of Plutarch's Eroticus (Amatorius)

This aim of this article is to reflect on Michel Foucault's reading of Plutarch's Eroticus in his Histoire de la sexualité, putting emphasis on the fact that, against what it is affirmed by the French thinker, the real debate is not, in the author's opinion, about true pleasure, that obtained by the erastés from his erómenos or that obtained by husbands from their wives, but the need to assign also love and friendship (éros kaì philia) to the conjugal love.

Local character of magnetic coupling in ionic solids

Magnetic interactions in ionic solids are studied using parameter-free methods designed to provide accurate energy differences associated with quantum states defining the Heisenberg constant J. For a series of ionic solids including KNiF3, K2NiF4, KCuF3, K2CuF4, and high- Tc parent compound La2CuO4, the J experimental value is quantitatively reproduced. This result has fundamental implications because J values have been calculated from a finite cluster model whereas experiments refer to infinite solids. The present study permits us to firmly establish that in these wide-gap insulators, J is determined from strongly local electronic interactions involving two magnetic centers only thus providing an ab initio support to commonly used model Hamiltonians.

L’ocell s’ha tornat gàbia. Indagacions sobre la subjectivitat a partir de Michel Foucault i la psicoanàlisi freudiana

La pregunta originària d’aquest treball girava entorn de la subjectivitat. Concretament,entorn d’una subjectivitat desposseïda. El treball pretenia explorar el descobrimentd’una manca de pertinença respecte allò que un és, el reconeixement d’una estranyesainstal·lada en allò que un sent de més seu, de més protegit i resguardat; allò de méspropi, de més pur i genuí: allò que, des d’una soledat inpertorbada, constitueix allò mésseu del si mateix. Aquest treball pretenia estirar el fil d’una desconfiança radicalrespecte tot allò que un creu de més inherent a ell, d’un procés de des-identificaciórespecte la pròpia voluntat, el desig, el gust, el plaer; de l’experiència de descobrir quequant un més segueix el seu desig més s’aliena, que quan un més és ell mateix menys espertany, que quan un més s’allibera més segueix el mandat d’un remitent llunyà,anònim i desconegut; estirar el fil, en definitiva, de la vivència de sentir el propi «cor»com un cos estrany.

The Arcuated Lintel and the "Serlian Motif". Imperial Identity, Architectural and Symbolic Interactions in Ancient Rome

Essay on the origin, use and development of the arcuated lintel in ancient Rome and the configuration of the so– called ‘Serlian motif’. These architectural elements will be related to the architecture of prestige on its technical, functional, visual and symbolic sphere. Its depictions, in addition to buildings, can offer a rich repertory of images that speak about the relations between visual culture, religion and power. Furthermore, the analyzed motifs will become important elements of the Western cultural legacy for centuries. The analysis of these events will contribute to the comprehension of the role played by some resources of ancient Rome architecture of prestige and its success

The Impact of a Character Posture Model on the Communication of Affect in an Immersive Virtual Environment

This paper presents the quantitative and qualitative findings from an experiment designed to evaluate a developing model of affective postures for full-body virtual characters in immersive virtual environments (IVEs). Forty-nine participants were each requested to explore a virtual environment by asking two virtual characters for instructions. The participants used a CAVE-like system to explore the environment. Participant responses and their impression of the virtual characters were evaluated through a wide variety of both quantitative and qualitative methods. Combining a controlled experimental approach with various data-collection methods provided a number of advantages such as providing a reason to the quantitative results. The quantitative results indicate that posture plays an important role in the communication of affect by virtual characters. The qualitative findings indicated that participants attribute a variety of psychological states to the behavioral cues displayed by virtual characters. In addition, participants tended to interpret the social context portrayed by the virtual characters in a holistic manner. This suggests that one aspect of the virtual scene colors the perception of the whole social context portrayed by the virtual characters. We conclude by discussing the importance of designing holistically congruent virtual characters especially in immersive settings.

The Reality of Neandertal Symbolic Behavior at the Grotte du Renne, Arcy-sur-Cure, France

The question of whether symbolically mediated behavior is exclusive to modern humans or shared with anatomically archaic populations such as the Neandertals is hotly debated. At the Grotte du Renne, Arcy-sur-Cure, France, the Châtelperronian levels contain Neandertal remains and large numbers of personal ornaments, decorated bone tools and colorants, but it has been suggested that this association reflects intrusion of the symbolic artifacts from the overlying Protoaurignacian and/or of the Neandertal remains from the underlying Mousterian.

Characterization and quantification of polyradical character

The decomposition of 〈͈Ŝ²〉 into atomic and diatomic contributions (local spin analysis) is used to detect and quantify the polyradical character of molecular systems. A model triradical system is studied in detail, and the local spin analysis is used to distinguish several patterns of local spin distributions and spin-spin interactions that can be found for different electronic states. How close a real molecular system is to an ideal system of k perfectly localized spin centers is utilized to define a measure of its k-radical character. The spin properties and triradical character of the lowest-lying electronic states of a number of all σ, all π, and σ-π organic triradicals are discussed in detail. The local spin contributions exhibit good correlation with experimental triradical stabilization energies
