From South to North? Mobility of Southern Italian Students at the Transition from the First to the Second Level University Degree

2018

In the last decades, the Italian University System has encountered several structural reforms aimed at making it more internationally competitive. Among them, the introduction of the University financial autonomy has triggered an “internal” competition among Universities to attract students from the entire country. Students’ enrollment at the first level has decreased significantly especially after the economic crisis of 2008, while the students’ migration from the South to the Central and Northern regions of the country has increased. These phenomena have created further inequalities within the country and a cultural and socio-economic loss for the South that does not appear to slow down. …

Photobleaching and Recovery Kinetics of a Palette of Carbon Nanodots Probed by In Situ Optical Spectroscopy

2022

Carbon dots (CDs) are a family of fluorescent nanoparticles displaying a wide range of interesting properties, which make them attractive for potential applications in different fields like bioimaging, photocatalysis, and many others. However, despite many years of dedicated studies, wide variations exist in the literature concerning the reported photostability of CDs, and even the photoluminescence mechanism is still unclear. Furthermore, an increasing number of recent studies have highlighted the photobleaching (PB) of CDs under intense UV or visible light beams. PB phenomena need to be fully addressed to optimize practical uses of CDs and can also provide information on the fundamental m…

Measurement of the top quark charge in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

2013

A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb[superscript −1] of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined to be 0.64 ± 0.02 (stat.) ± 0.08 (syst.) from the charges of the top quark decay products in single lepton t[¯ over t] candidate events. This excludes models that propose a heavy quark of electric charge −4/3, instead of the Standard Model top quark, with a significance of more than 8σ.

La competittività di una destinazione turistica

2013

Measuring destination competitiveness and identifying its determinants are strategic goals for pol-icy makers and tourism stakeholders. In order to do so, the availability of valid and reliable moni-toring tools is requested. In this context quantitative measurement tools, such as composite indi-cators, able to account for complexity and providing easily interpretable measures, represent a useful option. Nowadays composite indicators are commonly used for these aims but some criticism is suggested on how this happens. In this paper we provide some definitions of destination competitiveness and focus on related measurement approaches. In particular, supply-side competitiveness is distinguish…

The measurement of seasonality for tourism evaluation

2017

Seasonal variations in tourism demand represent one of the most challenging topics in tourism research. After highlighting the main pitfalls which characterize the majority of currently used indices for seasonal amplitude, the present work propose the implementation of a recently discusses a recently proposed index for the measurement of seasonality in tourism, based on the transportation problem approach. An adequate measurement of seasonality is a pre-requisite for the evaluation of the effectiveness of tourism policies aimed at reducing tourism demand imbalance.

Analysing tourist mobility: current issues and future challenges

2013

Tourism statistics are generally based on data collected only at one point of the travel, which, depending on the perspective of interest, can be the originating region or the destination one. Indeed, many tourism trips imply the visit to more than a single destination, since tourists move to visit several attraction to several destination or within the same destination. The analysis of tourist mobility presents several issues which are related both to the collection of information on multidestination trip behaviour and to the analysis of complex information such as the ones related with tourist itineraries. The present work aims at reviewing the main issues related with the analysis of tou…
