Analysis of heat wave effects on health by using generalized additive model and bootstrap-based model selection

Summary.  It is known that high summer temperature may lead to worsening health conditions among fragile individuals within exposed populations. It is also argued that multiday patterns of high temperature—heat waves—may have relevant effects on health. We discuss the possible measures of intensities of heat waves to be included in a generalized additive model explaining the number of hospital admissions that occurred during summer months in Milan. The issue of variable selection is central to the analysis: a computational method is discussed which may help in assessing the robustness of the model selection method. Eventually, we obtain evidence supporting the relevance of heat waves in driving adverse health episodes.     

Migration,Religion, and Residential Segregation at the Urban Level: The Case of Muslim Migrants in Rome and Milan

This article investigates residential segregation at the intraurban level of migrants in two Italian cities, Rome and Milan, considering religion as a point of reference in light of its pivotal role in terms of identity references for many migrants. The article focuses in particular on Muslim migrants—due to both the magnitude of their presence and complex issues related to their settlement in Italian cities. The analysis shows a low level of intraurban residential segregation of Muslim migrants in both cities, with some relevant differences related to national subgroups (e.g., a higher concentration for people coming from Bangladesh and Pakistan), so that religion seems not yet to be a main driver of residential choice for Muslim migrants. In light of both the low level of segregation of Muslim migrants and some features of Italian urban policies on migration and religion, we argue that residential concentration can currently play a beneficial role in terms of the insertion of migrants in Italian cities and fulfillment of some of their needs (e.g., availability of minority places of worship).     

Emigration and Immigration in Italy: Recent Trends

ABSTRACT: During the eighties Italy has evolved into being a receiver of immigration. However, the existence of large Italian communities abroad, and the persistence of exit migratory flows (although amply compensated by re-entry flows) show that the connotation of Italy as a country of emigration still persists. This paper points out the differing composition of present immigration flows to Italy compared to those of Italian migratory flows towards the more industrially advanced European countries over the past decades. The labour forces that constitute these present day immigration flows often possess medium to high educational qualifications, and are more frequently absorbed into the tertiary and agricultural markets, rather than the industrial sector. These immigrants rarely have regular, unionized occupations, and satisfy a demand for precarious, unstable labour which is in expansion in Italy, as in other countries. Furthermore, these immigration flows are directed not only towards those regions with high employment rates, but also to those with high unemployment rates. Thus, the implications are that the character of present day emigration can only be clearly understood by taking into account the highly segmented aspect of the labour market.
