Ethnic segregation in a metropolitan area of Italy: the case of Palermo
No full textLa 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 dell’indice di Duncan e di avere una performance migliore anche in termini di errore standardEthnic 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 metropolitan area of Palermo. We use individual data for all the population residing in the city at 31 December 2011, organised by ethnicity and neighbourhood ("quartiere"). Firstly, we describe the residential segregation of foreigners and, among other measures, we apply the Duncan and Duncan dissimilarity index. Then, we apply a recent methodological approach, which allows reducing the bias of the Duncan’s index and performs better than previous bias reduction techniques, in terms of both mean bias and MS
Time pattern of remittance behaviours in Italy
No full textThis paper intends to figure out why immigrants remit, what characteristicsthey have and, in particular, which of these individual characteristics influence (and inwhat sense) their propensity to remit. In particular, it intends to verify the existence of a"time effect" during the migration process. The time effect suppose that the propensityand the intensity of remittances becomes less consistent as far as the immigrantintegrates into the host country and the ties with the country of origin become lessintense. In practice, according to this hypothesis, the evolution of the migration plantowards stabilization in the new country, rather than to return home, would lead themigrant to invest more (humanly and economically) in the host country, while reducinghis emotional and economic commitment to the family left in the country of origin. Weuse the 2009 IT-Silc survey "Reddito e condizioni di vita delle famiglie con stranieri"carried on around 6,000 households having at least one foreigner component. Thissurvey provides many details on foreigner's characteristics, remittances attitudes andreturn plans, and allows us also to consider the composition of the family both in placeof origin and of destination
Residential segregation of foreigners: An analysis of the Italian city of Palermo
Full text linkEthnic 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 and performs better than previous bias reduction techniques, in terms of both mean bias and mean square error
Remittance behaviours of foreigners in Italy
No full textThis article investigates the determinants of remittance behaviours among foreigners in Italyand intends to gain a better understanding of the temporal pattern of remittances. The analysisis based on data from the 2009 “Italian Statistics on Income and Living Conditions of House-holds with Foreigners”. The decisions on whether to remit and how much to remit are sepa-rately yet simultaneously estimated using a zero-inflated beta regression model. The findingsreveal that remittances are driven by a mix of altruistic and self-interest motives that may per-sist for many years. Many covariates included in the model have a different effect on thepropensity to remit and on the relative amount of remittances. We find some evidence that theaverage propensity to remit follows an M-shaped trajectory over time. However, the modelspecification including only time and time squared proves that the inverted-U shape trajectory,well-established in the literature, still remains a better choice in terms of parsimoniousness andflexibility. Among those who remit, time since migration does not have any significant effecton the normalized amount remitted
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
