Prioritisation of alternatives with analytical hierarchy process plus response latency and web surveys

2014

This paper introduces a new method that combines the well-known analytical hierarchy process (AHP) with a response latency metric. The response latency is the time taken by respondents to make choices over pairwise comparisons. The analytical calculation of relative importance weights of the alternatives is made by using a response latency model previously validated in several case studies. This combination aims to overcome some drawbacks of the traditional AHP related to the use of a rating scale (the so-called Saaty scale), and it is a natural way to involve response latency in established decisionmaking methods. This new method can be profitably adopted in web surveys where it is easy to…

A distributional approach for measuring wage discrimination and occupational discrimination separately

2011

Numerous statistical methodologies regarding the study of discrimination are based on the well-known Blinder-Oaxaca (1973) decomposition. This divides the wage differential between men and women into one part, which can be explained by differences in individual characteristics, and another part, which is interpreted as discrimination. This decomposition ignores any distributional issues in evaluating discrimination, thus permitting, undesirably, compensation between positively and negatively discriminated women. Jenkins (1994) has criticized this aspect, instead preferring a distributional approach. Del Ri­o et al. (2010), using a distributional approach, which hinges on the deprivational a…

SEDENTARINESS AND EDUCATION CONTRIBUTE SIGNIFICANTLY TO SOCIOECONOMIC INEQUALITIES IN NON-COMMUNICABLE DISEASES

2018

In Europe, the main non-communicable diseases (NCDs), including diabetes, cardiovascular diseases, cancer, chronic respiratory diseases and mental disorders, all together account for an estimated 86% of the deaths and 77% of the disease burden. Of the six WHO regions, Europe is the most affected by NCDs [1]. The detection and control of physiological and behavioral risk factors (BRFs) remain the essential preventive strategy to counteract not only the average population’s exposure to the main NCDs, but also socioeconomic inequalities, which are related to chronic diseases. The scope of this work is to investigate socioeconomic inequalities among the European elderly in NCDs and BRFs for NCD…

Measuring sustainable economic development through a multidimensional Gini index

2016

This paper analyses the evolution of sustainable economic development inequality in Italy as regards the efforts made by each administrative Region, as a response to the main EU policies issued by the environmental and energy sector. For this purpose a multidimensional generalization of the Gini index has been performed, taking into account two different dimensions (energy and environment), in a time frame of six years (2008-2013). The multidimensional Gini results confirm the positive effect recorded by certain EU policies in determining a reduction in the inequality levels among the Italian Regions. A counterfactual analysis further underlined the relevant role played by the energetic dim…

A new bipartite matching approach for record linkage: the case of two big Italian databases

2022

In recent years, university student mobility in Italy has worsened the north-south economic divide. Therefore, studying this phenomenon and its determinants is necessary to provide helpful information to support socio-economic policies. Thus, this paper aims at integrating two big databases about university students in Italy: the first one is provided by the Ministry of University and Research, concerning the university careers of student cohorts; the second one is provided by the AlmaLaurea consortium, concerning the university experiences of graduates and their success in the labour market. Both databases contain socio-demographic information that complements each other. The proposed meth…

Distance Measures for Portfolio Selection

2017

The classical Markowitz approach to the portfolio selection problem (PSP) consists of selecting the portfolio that minimises the return variance for a given level of expected return. By solving the problem for different values of this expected return we obtain the Pareto efficient frontier, which is composed of non-dominated portfolios. The final user has to discriminate amongst these points by resorting to an external criterion in order to decide which portfolio to invest in. We propose to define an external portfolio that corresponds to a desired criterion, and to assess its distance from the Markowitz frontier in market allowing for short-sellings or not. We show that this distance is ab…

Compendio di sociologia

2019

Pur conservando la struttura dei principali manuali di sociologia generale, dei quali sono forniti alcuni riferimenti in bibliografia, questo compendio tratta in forma più sintetica i concetti basilari della disciplina. Tale scelta si rende funzionale a raggiungere i risultati che si concretizzeranno in una immediata conoscenza dei fondamentali riferimenti sul piano teorico che riguardano le principali dinamiche sociali. Per queste ragioni, l'attenzione è orientata in modo specifico alla trattazione dei gruppi sociali, delle istituzioni, delle variabili intervenienti negli scenari del mutamento sociale e, in generale, dei diversi fenomeni che costituiscono gli ambiti di interesse primario p…
