Global Divergence in Growth Regressions

2013

This paper extends the standard growth regression model by adding an assumption that a country follows the global technology frontier either fully or partially. This additional assumption changes significantly the growth regression model and its results in three main ways. First, it shows that although a country converges to its long-run growth path, this path can diverge from the countries at the global frontier. We measure the degree of divergence for each country and find that most indeed diverge from the frontier. Second, we estimate growth dynamics without controlling for additional variables. Third, our new method enables us to disentangle the effects of the explanatory variables on t…

A Multi-Objective Design Approach for the c Chart Considering Taguchi Loss Function

2014

The present paper proposes a multi-objective design approach for the c chart, considering in the optimization process of the chart parameters both the statistical and the economic objectives. In particular, the minimization of the hourly total quality related costs is the considered objective to carry out the economic goal, whereas the statistical objective is reached by the minimization the out-of-control average run length of the chart. A mixed integer non-linear constrained mathematical model is formulated to solve the treated multi-objective optimization problem, whereas the Pareto optimal frontier is described by the «-constraint method. In order to show the employment of the proposed …

Nei Luoghi del design. Azioni e interazioni

2008

Il testo raccoglie alcune riflessioni sulla definizione “Luogo” in relazione alla definizione di “Design” ambiguamente identificato con il termine “Industriale” quale connotazione imprescindibile della sua natura disciplinare. È nelle relazioni complesse tra i due termini: Luoghi e Design che si dispiegano i tre paragrafi del volume, veri filtri di lettura o “luoghi metaforici” per leggere la complessità in cui si trova ad operare oggi il design nel suo significato più ampio di progetto: Il primo filtro, che si avvale della coppia concettuale “astratto / concreto”, individua luoghi di relazioni tra strategie progettuali proprie della disciplina del design (sia legati ad artefatti comunicati…

Manufacturing export performance and public capital: an analysis by country technology position

2021

The objective of this paper is to examine the relationship between public capital and manufacturing export performance. It also aims at investigating whether this relationship depends on the proximity of a country's technology frontier. To achieve this, we adopted a methodology that estimates the elasticities of public capital as a non-rival factor in a model that considers factor intensity as a mechanism of industrial development. We use an interaction model with panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that in countries far from the technology frontier, public capital accumulation is an element of industrial development as opposed to co…

Principi e metodi di intervento sociale nelle catastrofi: il contributo di Lena Dominelli

2016

Il servizio sociale in Italia si sta aprendo all’esperienza e alla riflessione per la costruzione di sapere professionale specifico nell’ambito dell’intervento in emergenza. In altre realtà nazionali ed internazionali, la consapevolezza del ruolo del servizio sociale nelle emergenze è già acquisita da tempo e questa competenza fa parte della formazione ordinaria o comunque di percorsi di specializzazione consolidati. Anche in Italia sta maturando questo cambiamento, pur se in modo ancora diseguale, secondo le specificità territoriali e la messa in rete ancora a macchia di leopardo delle iniziative. In questo impegno di costruzione di sapere, può offrire elementi ulteriori di riflessione il …

Lampedusa 2016: per un dialogo tra generazioni

2016

Primo feedback su un progetto di mediazione comunitaria in corso a Lampedusa, dedicato alle relazioni giovani adulti in un'isola duramente provata dall'esperienza degli sbarchi, ma ancora di più dalla massiccia presenza di operatori dell'accoglienza e della sicurezza, la cui presenza ha alterato l'equilibrio comunitario. L’idea guida del progetto suppone che sia possibile attivare percorsi di gestione condivisa delle tensioni esistenti tra le componenti della generazione degli educatori (genitori, insegnanti, catechisti, specialisti impegnati in progetti per gli adolescenti), attraverso cui attivare la loro collaborazione sull’obiettivo comune di ritessere le relazioni tra le generazioni su…

Smart Cities and Eu growth strategy: a Comparison among European Cities

2015

The level of interest in smart cities has been growing during these last years. The academic literature (Holland, 2008; Caragliu et al., 2009, Nijkamp et al., 2011 and Lombardi et al., 2012) has identified a number of factors that characterise a city as smart, such as economic development, business-friendly, environmental sustainability, social innovation, information and knowledge process, and human and social capital. Thus, the smartness concept is strictly linked to urban efficiency in a multifaceted way as well as to citizens’ wellbeing through the use of appropriate technologies. Instead, from a “political perspective” smartness is mainly related to the ability of using ICT (Informatio…

Labor market matching with application to Finnish data

2014

This thesis studies labor market matching and takes use of a matching function, which describes the technology how unemployed job seekers and vacant jobs search, meet and form new employment relationships. The goal of the study is twofold: First is to provide a comprehensive critical review of previous literature covering both micro models as well as empirical applications. Major limitations in empirical studies are imperfect measures of variables as well as inability to account for all relevant factors making results methodology-sensitive. The second contribution is to estimate a matching function for Finland using annual data from 2006-2012 and thus giving the most recent knowledge on the…

Production and Efficiency in 21 Industrialized Countries from 1966 to 2007 to Analyse the Italy’s Decline: Application of a Stochastic Frontier Model…

2008

This paper uses a stochastic frontier production model to estimate the technical efficiency of 21 nations among the more industrialized countries in the world for the wide period from 1966 to 2007. A Cobb-Douglas with labour and capital as inputs, GDP as output and efficiency with exponential distribution appears to work good from a statistical point of view. This model is used to estimate in a bayesian approach the efficiency score of these 21 countries. The bayesian way, applied via Gibbs sampling, is here useful to avoid problems about the small number of observations. So, each efficiency score is obtained as mean of 10,000 draws. The results underline a general and progressive efficienc…
