Polisemia di nòmos e l'esordio di Hipp. de genitura
2016
Far from being, as has been said, “the bizarrest beginning of all the Hippocratic writings (...) deserving of therapy”, this paper aims to show that the opening words of the Hippocratic writing “On Generation” (νόμοϲ μὲν πάντα κρατύνει), in itself echoing a famous Pindaric motto, seem to be used first of all in order to evoke a cultural, intellectual and scientific world, in which the nòmos has become one of the most important keywords of the time. From this point of view, the Pindaric quotation seems to be played out on the wide semantic range of nòmos as well as on the ambiguous meaning of the verb κρατύνω, which in this embryological context denote specifically the consolidation and hard…
Roland Barthes. El sentido de la moda
2021
Roland Barthes devoted much of his intellectual interest to the phenomenon of fashion. Long before his famous Système de la Mode, he wrote numerous essays on the subject, mainly of a methodological nature, both to elaborate a coherent historiography of dress and to establish a semiology of dress itself, distinguishing –with Saussure– between costume (langue) and clothing (parole). Indeed, if dress is a heteroclite whole, like language for Saussure, the semiologist’s task is to reconstruct its functioning as a system of signs, not only in the dress described by the magazines (as he does in Système), but also in the dress actually worn. A set of essays, in short, of extreme importance for any…
Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.
2020
As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…
Seminaarin kahdeksan Augustaa : Isa Aspin tilapäisrunous ja nimipäivien vieton yleistyminen Suomessa
2019
Suomessa luterilainen nimipäivien viettämisen tapa, joka oli omaksuttu säätyläispiireihin Ruotsista, alkoi levitä kaikkialle maahan 1800-luvun viimeisinä vuosikymmeninä. Nimipäiviin liittyi monenlaisia juhlaperinteitä, joita noudatettiin esimerkiksi Jyväskylän seminaarin kaltaisessa oppilaitoksessa, mistä ne kulkeutuivat edelleen opiskelijoiden mukana eri puolille Suomea. Nuori seminaarilainen lsa Asp oli jo ennen opintojensa alkamista kirjoittanut paljon nimipäivä- ja muita merkkipäivärunoja. Onnittelurunous oli tärkeä osa hänen arjen kirjallista vuorovaikutustaan lähipiirinsä kanssa ja samalla keino tuoda julkisuuteen runojaan nuorena naisrunoilijana, jonka tekstejä ei ollut vielä juurika…
Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective
2017
The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…
Momentum-space structure of surface states in a topological semimetal with a nexus point of Dirac lines
2016
Three-dimensional topological semimetals come in different variants, either containing Weyl points or Dirac lines. Here we describe a more complicated momentum-space topological defect where several separate Dirac lines connect with each other, forming a momentum-space equivalent of the real-space nexus considered before for helium-3. Close to the nexus the Dirac lines exhibit a transition from type I to type II lines. We consider a general model of stacked honeycomb lattices with the symmetry of Bernal (AB) stacked graphite and show that the structural mirror symmetries in such systems protect the presence of the Dirac lines, and also naturally lead to the formation of the nexus. By the bu…
Place Names along the Júcar/Xúquer River in the Land of València
2012
Tras abandonar la Mancha el Júcar entra en el País Valenciano y a partir de su confluencia con el Cabriel, discurre primero encajado entre gargantas y luego sobre el llano aluvial de la Ribera, donde se le llama Xúquer. A ambos lados del río encontramos una toponimia –muchas veces poco transparente– que deriva de las características físicas de este río, de la protección ante sus avenidas, o de la vigilancia de los pasos o los caminos que lo atraviesan. Así pues, no sólo se trata de hidrónimos, sino también de odónimos, orónimos y toponimia de carácter defensivo. La metodología que hemos seguido parte del Nomenclàtor Toponímic de la Comunitat Valenciana, que cuenta con más de 100.000 topónim…
Geometrical-mechanical artefacts mediating tangent meaning: the Tangentograph
2012
This work deals with the didactical use of geometrical-mechanical artefacts to acquire tangent concept in vygotskian perspective. We adopt Rabardel’s theory on instru-mental approach to distinguish artefacts and instruments specially to evince the history-to-education ontogenesis-phylogenesis process. From this point of view we trace a historical-epistemological pathway for the tangent up to set an ad hoc didactical counterpart. Specifically in this paper we deepen the kinematical properties of the tangent (introducing the XVII century so called tractional motion) designing a laboratorial didactic pathway for 12th grade students with the use of a particular geometrical-mechanical artefact f…
La traduction des métaphores: le cas de Kassandra de Christa Wolf
2012
This paper analyzes, in a comparative way, the conceptual metaphors (Lakoff and Johnson, 1998) used in the German text «Kassandra» of Christa Wolf and in its Italian translation. The metaphors’ translation is important for two reasons. First it shows the socio-cultural aspects that turn around the source language and the target language. On the other hand, it can investigate the role of the language and the linguistic choices. This paper will analyze the metaphors’ translations using a mixed approach, both cognitive linguistics and semiotics but it also focuses on the translation theories. The analysis of metaphors allows us to understand better the comprehension of communicative intentiona…
Badania historyczno-systemowe procesów w wielkich społeczno-terytorialnych systemach: metody modelowania semantycznego w sektorze transportu
2017
Artykuł prezentuje metody modelowania semantycznego procesów zachodzących w sektorze transportu państw członkowskich UE i analizę historyczno-systemową grupy systemów terytorialno-społecznych (STS)w porównywaniu z innymi systemami. Za podstawę przyjęto semantykę opartą na taksonomii transportu kolejowego. Badano zmiany infrastruktury i pracy przewozowej na tle procesów wytwarzania PKB. Analizą objęto retrospektywnie okresy 30-, 20- i 15-letnie. Modelowanie identyfikuje zmiany fazowe w STS, obiektywizuje oceny wpływu czynników geopolitycznych na rozwój i trendy przed- i pokryzysowe.
