Investigation of the Electrophoretic Mobility of the Actinides Th, U, Np, Pu, and Am in Different Oxidation States.

2019

The electrophoretic mobilities (μe) of the actinides Th and U-Am in different oxidation states (prepared in 1 M HCl and 1 M HClO4) have been determined by capillary electrophoresis (CE)-inductively coupled plasma mass spectrometry (ICPMS) using 1 M acetic acid as the background electrolyte, which has proven to provide an excellent setup for trace analysis at environmentally relevant concentrations (1 × 10-9 M). The values are independent of the respective acid solution. The μe of the Pu oxidation states +III to +VI have been measured. They agree with both the available literature data and the redox-stable analogues (Eu(III), Th(IV), Np(V), U(VI)) that have also been investigated. The trend …

Separated Children’s Migration in the Mediterranean Sea. An Ethnohistorical Perspective

2016

In the imaginary of Italian people, the Island of Lampedusa (Italy) has always been considered a paradise destination for summer holidays. The beauty of this small island at the heart of the Mediterranean Sea, far from big harbors and cities, with its rich biodiversity and unspoilt nature, has made it a national and international tourist attraction. However, in recent years its name become associated with scenes of tragic, desperate journeys made by people of different origins trying to reach Europe from North African coasts. This shift exists not only in Italian people’s perception, but also all over the world, as the news related to Lampedusa and other Italian areas affected by this pheno…

Modes de représentation des trajectoires quotidiennes des habitants

2007

Representing the daily trajectories of individuals Current research on inhabitants' daily mobilities has confirmed that individual mobility strategies are based on activity programmes. In France, the Household Travel Survey (HTS) is one of the principal sources of information about individual travel behaviour. Despite some drawbacks, they are rich sources of spatio-temporal data, as well as providing information on individual and household characteristics. However, for daily mobilities to be analysed, the raw data need to be reorganized. This study is based on the Grenoble-area Household Travel Survey, carried out in 2002. We propose to explore the HTS data through examples of individual mo…

Corpi d’acqua. Memorie odeporiche di minori migranti in una prospettiva etnostorica

2019

The essay presents some results of an ethnographic survey conducted in Palermo (Sicily) in a host community for unaccompanied foreign minors, focusing on the collective imaginary of the sea that a group of migrant minors from South Africa in-corporated during their travels. It highlights, from an ethno-historical perspective, the oral narratives and life stories collected during the symbolic-liminal passage through the Mediterranean sea. The re-elaboration of time and space in the boat correlates to the “bodies of water” as a possible contribution to the prospective discourse on trau-ma, exclusion, survival of separated children.

Theoretical approaches for geometric optimization of urban forms : towards a fractal development of the city

2017

This thesis aims to establish a urban structure that optimizes inhabitant's preferences. In other words, we want to find out which city shape answers the best the residents' aspirations, according to their consumption preferences for urban and green amenities. By considering a theoretical field of study and by characterizing the population by a Cobb-Douglas behavioral pattern, we will build step by step a city, assuming successive arrivais of new individuals, in order to find out which geometric shape gives the most suitable answer. The final goal of this thesis is there to suggest a city with a fractal shape as an appro- priate answer to the resident's expectations. We will show that this …

Diversity of Lactobacillus species in deep carious lesions of primary molars

2010

AIM: This was to determine the prevalence of Lactobacilli (LB) species in different stages of caries progression and are considered as secondary invaders of existing carious lesions and specialists for caries progression. METHODS: Carious dentine samples were collected from 70 primary molars (M) during step-wise (S1, S2: n = 35 M) or one-step (O1: n = 35 M) caries treatment and after 11 months of temporary restorations (S3, O2). LB were identified by selected physiological and biochemical characteristics, ratio of lactic acid isomers, electrophoretic mobilities of lactic acid dehydrogenases, and shotgun mass mapping by MALDI mass spectrometry. RESULTS: LB were isolated from 46% of soft dent…

Chi ha bisogno della mobilità? Per una critica situata del new mobilities paradigm

2021

Nei vent’anni trascorsi dalla pubblicazione di “Sociology Beyond Societies” di John Urry (2000), il testo che ha anticipato e ispirato il successivo mobility turn nelle scienze sociali, si è assistito a un proliferare di discorsi sulla mobilità che hanno travalicato dipartimenti, riviste e discipline portando al centro della scena migrazioni, flussi turistici, viaggi virtuali, trasporti di merci e persone. Obiettivo di questo contributo è di indagare criticamente i processi e le condizioni di produzione del mobility turn e di rileggerne contenuti, attori e metodologie all’interno dell’operazione strategica che l’ha sostenuto. In particolare, muovendo da una delle domande fondative della geo…

Facets of Women’s Migration

2014

This volume collects papers presented during the sixth edition of the Summer School “Migration, Human Rights and Democracy”, organized by the University of Palermo (Italy) in September 2012, which focuses on specific topics concerning migrations and motilities questions in contemporary world, gathering many scholars, activists, NGO’s members and researchers interested in discussing these issues. The women’s migration here represents the main topic, which has been examined bringing into dialogue a variety of theoretical perspectives, within an interdisciplinary context which includes not only sociology, anthropology, psychology and political geography, but also linguistics and literature.

Mobilities and the network of personal technologies: Refining the understanding of mobility structure

2017

Our ambition here is to refine the various typologies that compose the mobility structure. We aim to complement the work done by Urry and investigate the role played in the structure of mobility by what we call the “network of personal technologies”. Our new model consists of four different levels: macro-mobilities, micro-mobilities, media mobility and disembodied mobilities. By “macro-mobilities,” we refer to the actions which imply consistent physical displacement, such as travels, tours and commuting. By “micro-mobilities,” we mean small-scale displacements, including bodily movements and emotions. With moving media, we refer both to the new mobility provided by the smartphone to the tra…
