Patrona The Oxford dictionary online defines obstruction, as “a thing that impedes or prevents passage or progress; an obstacle or blockage.” Nick Salvato’s eponymous book, multilayered and thought-provoking, is an original study of five phenomena that while they ‘torment’ scholars and impede inquiry, for the author “they may, if properly directed, be conducive to critical work and valuable, more broad..

No full textThe paper is the Italian translation of the speech held in German language by Professor Karl Pestalozzi (University of Basel) at a seminar on literature in April 2004 (Catholic University of Milan, Faculty for Foreign Languages).
The analysis focuses on what the author considers the richest, most original and spontaneous version of Keller’s novel Der grüne Heinrich. Of this version the author highlights the description of two main perspectives, the outer and the inner one. In particular, he focuses on the contrast between the narrative, i.e. ‘auctorial’ self, who tells and judges events afterwards, and the self, who lives them from inside his experience.
Aim of the work is the analysis of some passages of Keller’s novel, which underline Heinrich’s profound literary knowledge. Heinrich’s reading of the German classic and romantic literature becomes the vehicle, through which he can understand and judge who he is and what he experiences: focusing on this central question of the novel, Heinrich’s experience of Lesen und Erleben, the reader is invited to reflect on his own knowledge and experience of literary works
Sulle orme di Dio. I grandi mistici di ieri e di oggi
No full textIl presente volume è la traduzione in lingua italiana del testo di P.J. Card. Cordes, "Spuren-Sicherung. Mystiker bezeugen Gott" (2012). Nell’orizzonte dell’era moderna e secolarizzata l’autore focalizza la sua attenzione su alcuni grandi testimoni del vivo incontro con la risposta all’inappagabile desiderio del trascendente, iscritto nel cuore dell’uomo. A partire da figure del periodo aureo della mistica tedesca, Meister Eckard, Ildegarda di Bingen, Matilde di Magdeburgo, Giovanni Taulero, Enrico Suso, l’autore propone un’antologia di testi, nei quali è particolarmente vivo il segno della presenza di Dio nell’uomo che Lo ricerca. Testimoni di tale presenza sono anche grandi personalità dei tempi più moderni, come Blaise Pascal con il suo "Memoriale" e Dante Alighieri con la "Divina Commedia". Decisivi per un approfondimento sono inoltre alcune opere di autori come Henri de Lubac, Léon Bloy, Hans Urs von Balthasar, Jörg Splett, Jean Mouroux. Non manca infine un confronto con figure di spicco considerate testimoni di un “cristianesimo non religioso” o “cristianesimo senza Dio”, tra cui in particolare Dietrich Bonhoeffer e Michel de Certeau. Caratteristica dell’intera ricerca è una personale riflessione sull’identità dell’uomo, letta ripercorrendo alcune fondamentali tappe del pensiero occidentale, al fine di suscitare la riflessione dei lettori dall’interno dell’era secolarizzataThe volume is the Italian translation of the German text of P.J. Card. Cordes, "Spuren-Sicherung. Mystiker bezeugen Gott" (2012). The theme of the book is the human search for God, which the author underlines from inside the modern secularized world. To do so he focuses his attention on some thinkers of the past: through their works he stresses their importance of being testimonies of a vivid encounter with God, that is with the answer to the infinite human desire for the transcendental. The author gives voice to some German mystics such as Hildegard von Bingen, Mechthild von Magdeburg, Meister Eckard, but also to other important thinkers like Blaise Pascal with his work "Memorial" or Dante Alighieri with his work "Divine Comedy". The aim of the analysis is twofold: on the one hand the author personally ponders on the identity of western society, analyzing the history of mankind from the point of view of his desire of God. On the other hand he challenges his readers to reflect on this innate desire with the help of the selected authors
Influence of the contact geometry on single-walled carbon nanotube/Si photodetector response
No full textA systematic study of the optical response of photodetectors based on carbon nanotube/Si heterojunctions is performed by measuring the responsivity, the detectivity and the time response of the devices with different contact configurations. The sensors are obtained by dry transferring single-walled carbon nanotube films on the surface of n-doped Si substrate provided with a multifinger contact geometry. The experimental data show a consistent improvement of the photodetector parameters with the increase of the number of fingers without affecting the carbon nanotube film thickness for increase its optical transmittance as in previous experiments. The role of the electrical resistance of the carbon nanotube film is discussed. The obtained results confirm the method and suggest new perspectives in the use of nanostructured materials as part of semiconducting optical devices
Increasing efficiency in single walled carbon nanotube/n-Si photodetectors by voltage doping
No full textSingle walled carbon nanotube (SWCNT) ultrathin films were deposited on n doped Si substrates provided with three electrodes for photoconductive measurements. Without illumination the devices show good rectifier properties and holes mobility in the range 105 cm/V.s which makes very promising for fast switching applications. Measuring the current voltage characteristics of the SWCNT film under illumination, an increase in the device performance is observed when a voltage VG is applied to the third electrode. In particular, increasing VG towards the breakdown region, an increase of more than 10 times is recorded in the photocurrent and in the external quantum efficiency with respect to the values measured at VG=0. The experimental data are interpreted considering a hole doping of the SWCNT film by the action of the third electrode voltage VG
Dalla traduzione all’auto-traduzione. Quali cambiamenti linguistici comporta la “divulgazione culturale”?
No full textThrough the supplied theoretical background and translating examples, the paper aims to highlight the inevitable necessity of an interdisciplinary approach in the translation process. It aims to show that Translation Studies, like most scientific branches, cannot stand in isolation of the substantial findings of other disciplines. Linguistics and pragmatics, which have been predominant for many years, should therefore be regarded in close connection with other disciplines like for example human sciences. At a theoretical level, the paper starts from the ontological valence of language and the common identity of human beings (e.g. Augustine of Hippo 1841, 1841a). As a common root between languages and cultures, the common identity alludes to wider scientific research fields for the interpretation of foreign texts (e.g. H.G. Gadamer 1993, 1960/1990). It suggests the need to observe the translating experience, reasoning forward from the strict empirical and phenomenological points of view, in order to extend the perspective to further reflections on language and on the cultural function of linguistic signs by involving human studies. At a pragmatic level, examples of interlingual translations – by writers who are both authors and translators of the original text – are given in order to focus on the potentialities of each language and on the linguistic and cultural opportunities translators have in their encounter with the alien other. The starting point is a question posed by Umberto Eco (1996) – “What happens if the translator of a text is the author himself?”. Three translations of this kind are analyzed in the paper. The first two are English speeches written and translated into German by writer and artist Wolfgang Hildesheimer (1916-1991). The third one is the Italian translation by the Irish novelist and poet James Joyce (1882-1941) of Anna Livia Plurabelle, the eighth chapter of his novel Finnegans Wake. In contrast to the Joycean constructive approach to translation, the paper also shows the “interpreting and translating effort” undertaken by Hildesheimer of the first 56 lines of the text Anna Livia Plurabelle (Hildesheimer 1991a). The comparison between Joyce’s fulfilled self-translation and Hildesheimer’s “paraphrase” aims to highlight the linguistic and cultural challenges enclosed in both traditional and self-translations. Through a series of examples, the paper aims to evaluate the arduous and challenging experience described on the one hand by Hildesheimer’s idea of “untranslatability”, of the “impossibility” to reformulate a text as it originally was, and on the other hand by Joyce’s need to re-invent and re-create corresponding expressions, showing the many linguistic and cultural potentialities that a language has
Analisi linguistico-retorica di Joseph Ratzinger: "Das Gleichnis vom barmherzigen Samariter"
No full textL’esegesi operata da J. Ratzinger della “parabola del buon Samaritano” (Lc 10, 25-37) nel testo Jesus von Nazareth (Herder Verlag 2007) offre una lettura personale del brano evangelico che evidenzia la profondità e l’intensità di un vero e proprio cammino interiore. Tale cammino è espresso attraverso passaggi linguistico-retorici degni di nota, grazie ai quali l’immedesimazione personale si articola in un progressivo mescolarsi di voci e prospettive (ich, wir, wir alle, jeder). I tre livelli introspettivi in cui esso si articola sono lo specchio stilistico di una immersione dell’autore nell’iniziale punto di vista del narratore (l’evangelista Luca), nella successiva prospettiva del protagonista della parabola (il Samaritano) e infine nella più completa prospettiva del Dio fattosi prossimo in Gesú. In tale cammino il lettore è chiamato a coinvolgersi in prima persona. Gli artifici retorici, con i quali Ratzinger legge la risposta di Gesù contenuta nella parabola del Samaritano, aiutano a cogliere le sfumature semantiche racchiuse nel racconto, le quali svelano l’intento dell’atto informativo (la verità dell’insegnamento in esso racchiusa): divenire atto performativo volto a sfidare ogni lettore in una libera risposta personale.Ratzinger’s exegesis on “the parable of the good Samaritan” (Lk 10,25-37) in his work Jesus von Nazareth (Herder Verlag 2007) offers a personal reading of the evangelic passage, which highlights the depth and the intensity of a downright interior development. This development is expressed through noteworthy linguistic and rhetorical elements, which lead the reader to follow the author in his narration, developed in a graduated melding of voices and points of view (I, we, we all, everyone). The three evolving introspective levels are the stylistic mirror of the progressive author’s immersion into the text: first, the narrator’s starting point of view (Luke the Evangelist); second, the perspective of the parable’s protagonist (the Samaritan); finally, the holistic point of view of God made flesh and become neighbor in the person of Jesus. The reader is invited to personally involve himself in this interior developmental path. All rhetorical devices, with which Ratzinger reads Jesus’ answer contained in the parable, help the reader understand the semantic nuances of the evangelic passage. They reveal the aim of the “informative” act (the truth contained in it) to become “performative”, in order to challenge every reader in his free personal answer
Bi2Se3/n-Si Schottky Junctions for Near-Infrared Photodetectors
No full textBi2Se3 thin films with different thicknesses are deposited on prepatterned n-Si substrates by the vapor–solid deposition method, demonstrating photodetector performances in the visible and near-infrared range up to the telecommunication wavelength 1550 nm and showing response times as low as 126 ns. The current voltage characteristics measured in the temperature range 77–300 K indicate the formation of Schottky junctions at the interface between the two materials. The nature of the junctions is discussed considering the effect of disorder at the interface induced by the Bi2Se3 film granularity. The temperature dependence of the ideality factors and the Schottky barrier heights is consistent with a thermionic field effect mechanism governing the electron motion through the interface, which is responsible for the fast response of the photodetectors
