High-Grade Mylonites
2009
High-grade mylonites are formed at temperatures above 650 °C. They are relatively uncommon, probably because their conservation is problematic. Most mylonites formed under these conditions would tend to fully recrystallise which destroys and masks the mylonitic structure. Mylonitic features are only preserved if grain growth is somehow inhibited in the rock, e.g. by its polymineralic nature.
Con Biglietto di andata. raccontare l'emigrazione verso Stati Uniti e Argentina
2020
Tra i paesi che hanno conosciuto, e tutt’ora conoscono, flussi migratori di grande portata, l’esempio italiano è quasi unico per intensità, durata e varietà dei luoghi di destinazione, soprattutto nel periodo compreso tra gli ultimi quattro decenni dell’Ottocento e gli anni Settanta del Novecento, quando il fenomeno ha toccato il suo apice. Fra le molte destinazioni, gli Stati Uniti e l’Argentina, sono stati tra le mete preferite dagli italiani. Si è trattato di una storia sociale, di una storia di sofferenze ma anche della storia della navigazione, dell’economica, così come di quella culturale, tout court, per le forti influenze che gli italiani hanno esercitato, oltreatlantico, sull’archi…
Les déterminants de la mobilité régionale des bacheliers entrant à l'université
2007
This paper aims at understanding the regional mobility of new entrants to university. The regional mobility is marginal. But, the impact of social and academic characteristics shows that self selection processes exist. The combine effects of fields and regions impacts highlight the role of availability of university program on student choice.

Report WS6: Immigration and new inhabitants in the Gateway Cities
2012
It is in the last years that the planning discipline has fully recognized immigration issues as decisive for their role both in the urban studies and in the policy design. Nowadays, in Italy and Europe, the shifting social composition of the cities asks the planner for new cognitive instruments and new strategies for the interventions on urban systems. The present report resumes the results of the workshop “Immigration and new inhabitants in the gateway cities” which took place inside the IX Biennial of Towns and Town Planners of Europe, held in Genoa in September 2011. In the two days of debate, a number of Italian and European examples has been presented: the report underlines three issue…
Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system
2015
Published version of an article from the journal: Marine Ecology Progress Series. Also available from Inter Research. Http://dx.doi.org/10.3354/meps11103 Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and habitat transitions. During March 2012 to June 2013, we used acoustic tags and moored receivers to monitor the behaviour of Atlantic herring Clupea harengus L. (N = 47) throughout a range of habitats on the Skagerrak coast in southern Norway. Five of the tagged herring entered a former lake transformed into an artificial …
Migrācijas ietekme uz starptautisko biznesu, Latvijas darba tirgus
2018
Patreizējās demogrāfiskās izmaiņas Latvijā raisa vēlmi tās analizēt un izpētīt. Pašlaik Latvijas darba tirgus ir salīdzinoši sliktā formā, demogrāfiskā sarukuma, kurš pēdējā laikā pārņēmis Latviju, dēļ. Darba mērķis ir izpētīt un saprast vai Latvijas darba tirgum ir nepieciešama migrācija, lai normalizētu situāciju tajā un aizpildīttu tukšumu, kas radies demogrāfiskā sarukuma dēļ, un vai patlaban redzama migrācijas ietekme uz demogrāfiju, algām bezdarba līmeni, uzņēmumiem un Latvijas darba tirgu kopumā. Ņemot vērā patreizējās problēmas Latvijas darba tirgū, migrācija varētu būt adekvāts īslaicīgs problēmas risinājums, un šis darbs pierāda, ka migrācijas efekts būtu pieņemams. No otras puses…
Investigation of diffusion and electromigration of hydrogen in palladium and PdAg alloy
1999
Abstract Diffusion and electromigration of hydrogen in PdH 0.1 , Pd 77 Ag 23 H 0.1 and Pd 50 Ag 50 H 0.1 alloy were measured by means of resistivity method. It is known that hydrogen migrates towards the cathode within the temperature range of 300–473 K in the PdH 0.1 and Pd 77 Ag 23 H 0.1 system. In Pd 50 Ag 50 H 0.1 , hydrogen migrates towards the cathode below 400 K, but towards the anode at higher temperatures. Its effective valency increases together with temperature. At the same time it satisfies the linear dependence on inverse specific resistance ρ : Z eff = Z i +( k / ρ ). The constants Z i and k have the following values: (1.05±0.01) and −(3.81±0.04)×10 −8 Ω m for hydrogen in PdH …
Patterns of Transnational Urban Drift to Latvia
2021
This chapter extends the previous knowledge on the effects of migrants’ transnational lifestyle by studying residential patterns and life preferences of Latvian return migrants and arriving foreigners. We aim to explore the geographies and narratives from interviews with migrants who had shifted to more dynamic and prosperous urban/suburban locations. The contribution sends forward the interplay between immigration and return migration experiences by questioning: (1) What are the migratory flows’ geographical contexts? (2) How do they overlap and illuminate the process of ‘urban drift’? (3) How do the ‘urban drifters’ value their current life preferences and migratory experiences? Using sec…
Recognising forced migrants in transnational social work
2018
PurposeNation states’ neoliberal policies do not regard asylum seekers and undocumented migrants as deserving of a good life. Social work in welfare states is highly connected to the policies of nation states. There is a need to address theories in social work that have a transnational focus at the local level. Axel Honneth’s recognition theory enables an approach to forced migration from the direction of personal relations and personhood itself. The core idea is that if people cannot gain recognition, this causes harm to their self-realisation. The purpose of this paper is discuss how the recognition theory overcomes a national focus in social work.Design/methodology/approachThis paper is …
