β1 integrin signaling promotes neuronal migration along vascular scaffolds in the post-stroke brain

2017

Cerebral ischemic stroke is a main cause of chronic disability. However, there is currently no effective treatment to promote recovery from stroke-induced neurological symptoms. Recent studies suggest that after stroke, immature neurons, referred to as neuroblasts, generated in a neurogenic niche, the ventricular-subventricular zone, migrate toward the injured area, where they differentiate into mature neurons. Interventions that increase the number of neuroblasts distributed at and around the lesion facilitate neuronal repair in rodent models for ischemic stroke, suggesting that promoting neuroblast migration in the post-stroke brain could improve efficient neuronal regeneration. To move t…

The routes of Southern Italy university students: an explorative analysis

2022

The neoclassical migration approach postulates that different conditions in labour markets among territories are the driving forces behind migration. On the other hand, exponents of the new economics of migration argue that the decision to move is not made at the individual level. Considering migration as the result of a decision taken within a social network helps to explain the so-called chain migration. In this paper, we pay attention to the migratory chain of university students. This work introduces a statistical technique to “classify” migratory chains of students living in Sicily, Sardinia or Apulia, and enrolled in some centre-north regions from 2008 to 2017.

Student mobility: A systemic approach to preferential patterns in higher education

2022

The thesis is a collection of three essays with a “fil rouge”, namely the study of Italian student mobility, 2008 to 2017, analyzed systemically. The main objective of the thesis is to develop statistical methods suitable to identifying preferential mobility patterns starting from the micro-data of a mobility network and applying these methods to reveal preferential patterns of mobility among Italian students with a particular focus on students from Sicily. To the best of our knowledge, this is the first time that chain migration, within the framework of a network analysis, has been applied to the study of Italian student mobility. In each of the three chapters, there are data analysis tool…

Student mobility in higher education: Sicilian outflow network and chain migrations

2019

The most important student mobility (SM) flow in Italy is from the Southern to the Central-Northern regions, a phenomenon that has been magnified by an increasing number of outgoing students from Sicily over the last decade. In this paper, we rely upon micro-data of university enrollment and students' personal records for three cohorts of freshmen, in order to investigate preferential patterns of SM from Sicily toward universities in other regions. Our main goal is to reveal the existence of chain migrations, where students from a particular geographical area move towards a particular destination to follow other students that have previously moved. The paper provides aspects that are innova…
