Exactly solvable relativistic model with the anomalous interaction
2010
A special class of Dirac-Pauli equations with time-like vector potentials of an external field is investigated. An exactly solvable relativistic model describing the anomalous interaction of a neutral Dirac fermion with a cylindrically symmetric external electromagnetic field is presented. The related external field is a superposition of the electric field generated by a charged infinite filament and the magnetic field generated by a straight line current. In the nonrelativistic approximation the considered model is reduced to the integrable Pron'ko-Stroganov model.
"Hei mitä tää ny tarkottaa?" : experiences of intercultural communication and linguistic shock while using English abroad
2016
Globalisaation ja kansainvälistymisen myötä korkeakouluopiskelijoiden kansainvälinen liikkuvuus on lisääntynyt huomattavasti. Ulkomailla oleskelu on tarjonnut monille hyvinkin positiivisia kokemuksia, mutta uudessa kulttuurissa eri kielellä toimiminen voi aiheuttaa myös yllättäviä ongelmatilanteita. Tutkimuksen teoriataustan aloittaa katsaus kansainväliseen opiskelijaliikkuvuuteen, jonka jälkeen esitellään muutamia tärkeimpiä kulttuurienvälisen viestinnän teorioita. Kulttuurienvälinen viestintäkompetenssi on myös olennainen tässä tutkimuksessa, joten myös siitä keskustellaan. Kielishokki ilmiönä esitellään aluksi sekä kulttuurisesta että kielellisestä näkökulmasta, jonka jälkeen tarkastella…

Superdiversity perspective and the sociolinguistics of social media
2018
This chapter shows how the superdiversity perspective suggested in recent critical sociolinguistics provides the study of social media discourse and communication with a useful approach to conceptualizing and empirically investigating complex and multiple axes of diversity and difference in social media practices. It discusses recent work in sociolinguistics of social media, highlighting how social media practices illustrate many of the aspects of contemporary social life and communication that are considered symptomatic of superdiversity. It shows how research in this field has moved from viewing superdiversity as a quality or quantity characterizing specific places, spaces, groups and net…
Dal Virgilio russo al Tolstoj rosso, e ritorno: Epopea, nazione e senso del tempo nella teoria letteraria sovietica.
2006
Nella teoria letteraria sovietica sono continui gli appelli alla creazione di un epos: negli anni Venti, però, la richiesta è di una nuova forma epica, mentre a stalinismo affermato si intende che il modello sia il "Romanzo epico" sul modello tolstoiano. Questo cambio di accento può essere collegato con il passaggio ideologico dall'internazionalismo rivoluzionario al nazionalismo granderusso.
Researching Adolescents’ Linguistic Repertoires in Multilingual Areas : Case Studies from South Tyrol and Finland
2023
In this chapter we present and compare two research experiences in the domain of linguistic repertoires (LRs) applied to the field of education. Our aim is to elucidate how we used different combinations of methods for data generation in the trilingual (German, Italian and Ladin) Italian province of South Tyrol and the bilingual (Finnish and Swedish) coastal regions of Finland in order to map the LRs of young multilingual participants aged 10 to 19. We investigated different aspects of their LRs (representations, use and trajectories) with multiple methods, ranging from more traditional sociolinguistic surveys such as questionnaires and inter views to multimodal and task-based methods such …
Search for ultrarelativistic magnetic monopoles with the Pierre Auger Observatory
2016
We present a search for ultra-relativistic magnetic monopoles with the Pierre Auger Observatory. Such particles, possibly a relic of phase transitions in the early universe, would deposit a large amount of energy along their path through the atmosphere, comparable to that of ultrahigh-energy cosmic rays (UHECRs). The air shower profile of a magnetic monopole can be effectively distinguished by the fluorescence detector from that of standard UHECRs. No candidate was found in the data collected between 2004 and 2012, with an expected background of less than 0.1 event from UHECRs. The corresponding 90% confidence level (C.L.) upper limits on the flux of ultra-relativistic magnetic monopoles ra…
Stability of hydrodynamical relativistic planar jets
2004
The effects of relativistic dynamics and thermodynamics in the development of Kelvin-Helmholtz instabilities in planar, relativistic jets along the early phases (namely linear and saturation phases) of evolution has been studied by a combination of linear stability analysis and high-resolution numerical simulations for the most unstable first reflection modes in the temporal approach. Three different values of the jet Lorentz factor (5, 10 and 20) and a few different values of specific internal energy of the jet matter (from 0.08 to $60.0 c^2$) have been considered. Figures illustrating the evolution of the perturbations are also shown.
L'ingegner Zamjatin e la rivolta della fantasia
2012
Evgenii Zamiatin worked as an engineer while pursuing his literary career; in the eyes of his contemporaries, this was one relevant trait of his image. His masterpiece, the novel “We”, however, depicts a deeply pessimistic picture of an over-rational future society. This depiction contains, moreover, a number of attributes that can be traced back to Zamiatin's satirical picture of England in his novella “The Islanders”. Was this meant to be a warning against the dangers of technology, or against the developments of the bolshevik westernizing ideology? Was this engineer an enemy of rational thinking? The language of mathematics plays a relevant role in the novel's figural system; maybe, part…
