Distance from diasporas and immigrants’ location choice: evidence from Italy
No full textDiasporas play a fundamental role in explaining the location choice of new immigrants. We investigate the spatial dimension of diaspora externalities focusing on immigrants in Italian local labour market areas (LLMAs). We show that the net pull effect of diasporas spills over an estimated average distance of 82 km. We find evidence of negative spatial spillovers at greater geographical distances, suggesting a competition effect from neighbouring diasporas. Ethnic-specific labour markets and ethnic consumption externalities are important channels through which the distance–decay effects of diasporas take place. We also find that the spatial effects of diasporas are highly heterogeneous across gender and origin countries
Population change and international and internal migration in Italy, 2002-2017: Ravenstein revisited
Full text linkIn 1885, Ravenstein formulated his “laws” of migration, based on the experience of the British Isles. In a further 1889 paper, he extended his analysis as a tour d’horizon of migration and population changes in other nations, including Italy. Even if social and economic processes including globalisation and rising mobility have changed the world since then, Ravenstein’s “laws” remain a point of reference today. Harnessing theoretical and methodological advances made since the 19th century, this paper describes and seeks to explain the role of international and internal migration in regional population change in Italy from 2002-2017. This paper pro-vides the first geographically detailed migration analysis for the country’s 611 Local Labour Market Areas (LLMAs), using register-based migration and population data. Our contribution focuses on several of Ravenstein’s “laws” relating to gender (differ-ences between men and women), natives and non-natives (differences between the Italian and the foreign population), distance migrated from origin to destination, and the role of the economy in shaping push and pull factors of migration. The results show that international migration is more prominent among men than women. In the case of internal moves, the rates of migration among men and women are simi-lar, and internal migration is more prominent among the foreign than the native Italian population. Overall, international migration gains contribute substantially more to population change than internal migration gains and losses do. In Italy, the effects of persistent economic imbalances and of distance on migration patterns are not in line with Ravenstein’s hypotheses: not all areas with high unemployment show an effect of dispersion, nor does distance always act as a deterrent to migration. The geographically detailed analysis presented here illustrates the temporal and spatial coexistence of diverse international and internal migration processes depending on local characteristics, as well as the importance of the economic or administrative centres as the driving force behind national patterns. Our results show that, even 130 years after their formulation, Ravenstein’s migration “laws” (more accurately called “hypotheses” today) are still a valuable starting point in assessing and understanding migration processes and their role in regional population change
Migration Responses to Earthquakes. Evidence from Italy
No full textIn this paper, we analyze the migration responses to natural disasters by focusing on the three most devastating earthquakes in Italy in recent decades: L'Aquila 2009, Emilia Romagna 2012, and Central Italy 2016. Using municipality-level data for 2002-2019 and adopting a new difference-in-difference approach with multiple periods and multiple groups, we evaluate the causal effect of these events on internal and international inbound and outbound migration of both Italian and foreign citizens. The results suggest that, despite the massive destruction, there is no evidence that these earthquakes significantly impacted the migration of Italian citizens. We only found evidence of the effect of the earthquake in L'Aquila on the short-distance migration of foreign citizens
Migration Responses to Earthquakes: Evidence from Italy
Full text linkIn this paper, we analyze the migration responses to natural disasters by focusing
on the three most devastating earthquakes in Italy in recent decades: L’Aquila 2009,
Emilia Romagna 2012, and Central Italy 2016. Using municipality-level data for 2002–

The effect of internal migration on regional growth in Italy. A dynamic spatial panel data analysis
No full textis study assesses the effect of internal migration on regional growth in Italy at the NUTS-3 level over
the period 2002-2019. e composition of the internal migration flows of the working-age population in
Italy during the sample period appears substantially heterogeneous in nationality and labor skills. e
analysis considers this heterogeneity, estimating various specifications of the dynamic spatial model and
controlling for the endogeneity of migration variables through a control function approach. e evidence
suggests that the internal migration of Italian citizens has a positive direct and spillover impact on regional
growth, slowing down the convergence process. On the contrary, there is no evidence of a significant effect
of internal migration of foreign citizens. Taking the skill composition of internal movements of Italian
citizens into account, the adverse impact on convergence is magnified, thus corroborating the skill-selective
hypothesis. Finally, the diverging impact of internal migration increases with the distance of migration
flow

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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
