Among the numerous fields of the social intervention, this paper focus on the measures facilitating the integration of the foreigner minors. The intercultural education is the favourite approach as it represents the natural “landing” of a multi-ethnic society aiming to set off the cultural differences on the base of a symbiotic and empathic exchange. What is, in particular, the effectiveness of the intervention measures centred on the linguistic factor? We intend to answer this question analysing the typology of the courses, the instruments, the financial and human resources employed in a context of recent installation of immigrants (and their descendants): Apulia Region in Southern Italy.

Cette étude vise à analyser les migrants qui arrivent sur la côte Nord de la Méditerranée, dans notre cas, en Italie. Nous considérerons de plus près un segment spécifique de la mobilité internationale, c’est à dire le triangle migratoire Tunisie - Libye - Italie en nous intéressant à la variété et la réelle efficacité des moyens mis en place pour contrecarrer le phénomène tout en essayant de saisir les principales caractéristiques démographiques des immigrants illégaux.

Main aims of this study are the demonstration of the effectiveness of a non-weighted indicator of mortality: the total mortality rate and its calculation for the Italian population using the data contained in the cohort life tables calculated for Italy for the cohorts 1872-1917. The construction of a non-weighted (synthetic) indicator of mortality has not been matter of detailed discussion in the scientific literature and, as a matter of fact, there’s only a very limited number of publications on this subject (Sardon, 1993 and 1998; Termote, 1998). We would like to focus on this indicator for its interesting features. First, it is additive in the sense that the application of a non-weighted sum procedure allows the local decomposition of the index. Moreover, non-weighted indicators are sensitive to the level of disaggregation by age, unlike the weighted ones. Being, above all, a theoretical study, the main result of the present work is to demonstrate that the total mortality rate has a key advantage over similar indicators based on a weighted sum, because in space/temporal comparison, it can neutralize the bias resulting from dynamic factors, like age−specific lifestyles resulting in different mortality rates which, as emphasized in the literature, change over time and space. The adoption of this procedures can neutralize the homogenization effect, a central feature of all weighted sum procedures.
