Ethnic segregation in a metropolitan area of Italy: the case of Palermo
2015
La segregazione residenziale etnica in Italia è una questione emergente, che sarà fondamentale nella definizione e attuazione di politiche urbanistiche e sociali. Questo articolo si focalizza sull’analisi del fenomeno nel comune di Palermo. Utilizziamo i dati della popolazione residente in città nel 2011 in tutti i quartieri suddivisa per etnia. Facciamo dapprima ricorso a tecniche di analisi spaziale tradizionale al fine di descrivere la segregazione residenziale degli stranieri e, tra le altre misure, calcoliamo l'indice di dissimilarità di Duncan e Duncan. Successivamente, applichiamo un approccio metodologico recentemente proposto in letteratura che consente di correggere la distorsione…
Structural Parameters under Partial Least Squares and Covariance-Based Structural Equation Modeling : A Comment on Yuan and Deng (2021)
2023
In their article, Yuan and Deng argue that a structural parameter under partial least squares structural equation modeling (PLS-SEM) is zero if and only if the same structural parameter is zero under covariance-based structural equation modeling (CB-SEM). Yuan and Deng then conclude that statistical tests on individual structural parameters assessing the null hypothesis of no effect can achieve the same purpose in CB-SEM and PLS-SEM. Our response to their article highlights that the relationship they find between PLS-SEM and CB-SEM structural parameters is not universally valid, and that consequently, tests on individual parameters in CB-SEM and PLS-SEM generally do not fulfill the same pur…
Residential segregation of foreigners: an analysis of the Italian city of Palermo
2015
Ethnic residential segregation in Italy is an emerging key question, which will be crucial in the definition and implementation of both urbanistic and social policies. This paper focuses on this phenomenon in the Italian city of Palermo. We use individual data for all the population residing in the city at 31 December 2011, organized by ethnicity and district. Firstly, we describe the spatial distribution and the residential segregation of foreigners in the city, applying many different segregation measures. Among the others, we also apply the Duncan and Duncan dissimilarity index. Finally, we apply a recent methodological approach, which allows reducing the bias of the Duncan’s index…
