Immigrant Crime and Legal Status: Evidence from Repeated Amnesty Programs
Full text linkDo general amnesty programs lead to reductions in the crime rate among immigrants? We answer this question by exploiting cross-sectional and time variation in the number of immigrants legalized by the enactment of repeated amnesty programs between 1990 and 2005 in Italy. We address the potential endogeneity of the 'legalization treatment' by instrumenting the actual number of legalized immigrants with alternative predicted measures based on past amnesty applications patterns and residential choices of documented and undocumented immigrants. We find that, in the year following an amnesty, regions in which a higher share of immigrants obtained legal status experienced a greater decline in non-EU immigrant crime rates, relative to other regions. The effect is statistically significant but relatively small and not persistent. In further results, we fail to find any evidence of substitution in the criminal market from other population groups-namely, EU immigrants and Italian citizens-and we observe a small and not persistent reduction in total offenses

Cittadini senza diritti: abitare e lavorare a Milano da clandestini: Dati Naga 2000-2006
No full textLo scopo di questo rapporto è di presentare le principali caratteristiche socio-
demografiche dell'utenza Naga (Associazione Volontaria di Assistenza SocioSanitaria
e per i Diritti di Stranieri e Nomadi Onlus), che costituisce una delle più grandi banche dati sull'immigrazione irregolare. A tal fine analizzeremo i dati contenuti nelle cartelle
mediche del Naga per i pazienti che sono stati registrati tra il gennaio 2000 e il
dicembre 2006, soffermandoci sulla loro nazionalità, genere, situazione familiare,
anzianità migratoria, livello di istruzione, condizione lavorativa e situazione abitativa.
D'analisi emerge un quadro delle caratteristiche e delle condizioni dei migranti privi
di permesso di soggiorno del tutto diverso da quello spesso proposto nel dibattito
politico e mediatico italiano. Gli immigrati irregolari sono giovani giunti di recente in Italia, ma hanno livelli di istruzione e tassi di occupazione che eguagliano -se non
addirittura superano - quelli della popolazione residente in Italia. Le loro condizioni socioabitative, invece, sono assolutamente critiche e lontanissime dagli standard italiani
L’immigrazione irregolare in tempo di crisi
No full textIl lavoro utilizza tre diverse basi di microdati per quantificare l’effetto della recessione economica sugli immigrati irregolari e mettere a confronto i loro esiti occupazionali con quelli sperimentati nello stesso periodo dai nativi e dagli immigrati regolarmente soggiornanti in Italia. Questo è il primo studio a documentare un fortissimo peggioramento degli esiti lavorativi e della condizione abitativa durante la crisi economica iniziata nel 2008 fra gli immigrati privi di regolare permesso di soggiorno. In particolare, l’analisi dimostra che il calo della percentuale di occupati fra i lavoratori stranieri regolari è circa un terzo di quello degli immigrati irregolari. Inoltre, contrariamente a quanto osservato per la componente regolare dell’immigrazione, il calo dell’occupazione colpisce indistintamente entrambi i generi. La popolazione irregolare pare quindi caratterizzata da una particolare vulnerabilità sul mercato del lavoro, che si somma a quella che affligge la popolazione immigrata regolare.This paper analyses microdata from three different sources in order to quantify the impact of the economic recession on undocumented immigrants in Italy and to compare their labour market outcomes in recent years with the performance of native workers and documented immigrants. This study documents for the first time a dramatic deterioration of employment outcomes and housing conditions of undocumented immigrants during the economic crisis started in 2008. In particular, the reduction in the share of employed workers is about three times larger among immigrants lacking legal status than among legally resident immigrants. Differently from what observed for this latter group, among undocumented immigrants the fall in employment affects both genders in a similar way. If immigrant workers are generally more vulnerable in the labour market than natives, the lack of legal status is associated with even higher exposure to the detrimental effects of economic downturns
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
