What keeps young adults in permanent poverty? A comparative analysis using ECHP
2009
Abstract Previous studies suggest that there are strong differences in the rates of youth poverty across European countries. Rather surprisingly, it is found to be high in Scandinavian countries, and relatively speaking, lower in Mediterranean and Anglo-Saxon countries. This somewhat unexpected finding prompts the question whether the incidence of poverty is an appropriate measure of youth disadvantage. Instead of considering poverty rates we consider the length of recorded poverty spells, taking into account explicitly the temporal sequencing of the episodes of poverty. Using the European Community Household Panel, individuals are classified into different groups of poverty permanence, eac…
Bayesian joint ordinal and survival modeling for breast cancer risk assessment
2016
We propose a joint model to analyze the structure and intensity of the association between longitudinal measurements of an ordinal marker and time to a relevant event. The longitudinal process is defined in terms of a proportional-odds cumulative logit model. Time-to-event is modeled through a left-truncated proportionalhazards model, which incorporates information of the longitudinal marker as well as baseline covariates. Both longitudinal and survival processes are connected by means of a common vector of random effects. General inferences are discussed under the Bayesian approach and include the posterior distribution of the probabilities associated to each longitudinal category and the …
The Role of the Integrated Public Transport Network for Reducing the Congestion in the City of Palermo
2019
The railway link of Palermo is part of the Palermo – Trapani railway line and it is located in the urban site of Palermo. Works funded by the European Union have been started in 2008 for developing a metropolitan service through the improvement of the infrastructure and of the transport service characteristics. The aim of the paper is the analysis of the capacity of the railway infrastructure in terms of frequency and integration with the public transport service of Palermo. Using the Origin-Destination matrix of the Urban Transport Plan of Palermo, the competition between the private car mode and the public transport mode has been simulated, taking into account the improving of the railway…
How strategic needs influence alliance formation and their governance modes: An empirical study in the Italian biopharmaceutical industry
2011
Firms enter strategic alliances for various reasons, and the motives behind formation of these alliances are one of main research subjects in the management field. The large literature on the issue has highlighted how alliances answer to a strategic need for collaboration that is the need to improve competitive strength through collaboration agreements. However, the study here addresses the strategic need perspective to alliances under a more specific point of view. We question what kind of competitive strengths firms aim at acquiring through inter-firm relationships. By reviewing of the most relevant literature on the issue we assume that alliances respond to three principal strategic need…
Fiscal consolidation and financial reforms
2015
We use data for a panel of 17 countries over the period 1980-2005 to investigate the impact of fiscal consolidation on the likelihood of financial reforms. We show that fiscal adjustments do not boost the implementation of financial reforms. However, tax-driven fiscal consolidation programs raise the likelihood of banking sector reforms. Moreover, we find that: (i) an increase in the degree of trade openness makes countries less likely to implement financial reforms; (ii) an increase in the interest rate spreads accelerates the path of financial reforms, especially, external capital account reforms; and (iii) an improvement in the quality of political institutions strongly enhances the prob…

LA "SOFFERENZA FORMATIVA": UN'ANALISI PER COORTE DI IMMATRICOLATI
2007
La riforma universitaria entrata in vigore nell’a.a. 2001/02 ha portato sostanziali cambiamenti nel sistema accademico. Tra questi, l’introduzione dei crediti formativi ha avuto l’obiettivo di riformulare il criterio di valutazione della performance dello studente con l’auspicio, anche, della riduzione dei tempi impiegati per conseguire il titolo. Dopo circa sei anni ci si comincia ad interrogare sull’impatto che tale riforma ha avuto e a valutarne l’efficacia. Gli aspetti da dover tenere in considerazione sono molteplici e il presente lavoro ha voluto focalizzare l’attenzione sulla performance universitaria degli studenti e le sue determinanti. Prendendo in considerazione la coorte di imma…
Poverty Permanence Among European Youth
2008
Previous studies suggest that Scandinavian countries are the ones with the highest rates of youth poverty in Europe. This somewhat unexpected finding prompts the question whether the incidence of poverty is an appropriate measure of youth disadvantage. Instead of considering poverty rates we define here youth disadvantage in terms of the number of periods an individual is recorded to be below the poverty line. Using the European Community Household Panel, individuals are classified into different groups of poverty permanence, each reflecting severity of social disadvantage. Based on these categories we implement a generalized ordinal logit model to assess the various factors associated with…
