Comparative Analysis of Student Learning: Technical, Methodological and Result Assessing of PISA-OECD and INVALSI-Italian Systems .

PISA is the most extensive international survey promoted by the OECD in the field of education, which measures the skills of fifteen-year-old students from more than 80 participating countries every three years. INVALSI are written tests carried out every year by all Italian students in some key moments of the school cycle, to evaluate the levels of some fundamental skills in Italian, Mathematics and English. Our comparison is made up to 2018, the last year of the PISA-OECD survey, even if INVALSI was carried out for the last edition in 2022. Our analysis focuses attention on the common part of the reference populations, which are the 15-year-old students of the 2nd class of secondary schools of II degree, where both sources give a similar picture of the students

Chapter Exploring competitiveness and wellbeing in Italy by spatial principal component analysis

Well being is a multidimensional phenomenon, that cannot be measured by a single descriptive indicator and that, it should be represented by multiple dimensions. It requires, to be measured by combination of different dimensions that can be considered together as components of the phenomenon. This combination can be obtained by applying methodologies knows as Composite Indicators (CIs). CIs are largely used to have a comprehensive view on a phenomenon that cannot be captured by a single indicator. Principal Component Analysis (PCA) is one of the most popular multivariate statistical technique used for reducing data with many dimension, and often well being indicators are obtained using PCA. PCA is implicitly based on a reflective measurement model that it non suitable for all types of indicators. Mazziotta and Pareto (2013) in their paper discuss the use and misuse of PCA for measuring well-being. The classical PCA is not suitable for data collected on the territory because it does not take into account the spatial autocorrelation present in the data. The aim of this paper is to propose the use of Spatial Principal Component Analysis for measuring well being in the Italian Provinces

Indagine sui tossicodipendenti presso i servizi socioterapeutici in terra di Bari

Nella presente indagine, la fonte statistica è rappresentata dalle cartelle terapeutiche compilate dagli operatori socio-sanitari nel corso di colloqui (avvenuti nell’ultimo decennio) con 318 tossicodipendenti curati presso le comunità terapeutiche: Associazione Pugliese Rilancio (A.P.Ri.), Lorusso-Cipparoli, Centro Aiuto Psico-Sociale (CAPS); e con 331 fruitori del Ser.T. della Asl Ba/4 (campione casuale stratificato proporzionalmente all’utenza di tali strutture ricettive). Le informazioni messe a disposizione hanno consentito di ottenere, oltre quelle riguardanti la situazione familiare, notizie socio-demografiche, sui rapporti con l’istituzione scolastica, sulla situazione lavorativa, su quella penale, sul rapporto con le sostanze stupefacenti, e sui tempi di completamento del programma terapeutico

The Italian judicial offices productivity in almost 130 years of cognition civil procedures

In Italy, one of the hinge points on which the concept of State leans - the Justice - has slipped in a deep crisis more and more since remarkable difficulties in its internal reorganization are accompanied to the natural process of review in the civil society in evolution. The more evident external aspects of such crisis are translated in the slowness of the judicial mechanism, in the high cost of its antiquated procedures and in the difference of the sentences for degrees of judgment. To comfort or to contradict this or that thesis, also, sometimes statistic data are brought in contrast from each other, because of what they define is not well specified. Wanting to give clarity, it is first of all necessary to delimit this analysis to the procedure of cognition, essential unit of the civil trial activity, for an objective knowledge of the phenomenon from the quantitative point of view, to be able to supply stable terms of reference for a better interpretation of the facts and a more serious search of the causes and the effects, reaching a suitable territorial distribution of the enquirer personnel, judging or not. The analysis of some statistic indicators (i.e., the procedures duration, the index of disposal, the percentage variation of pending) derived by the data related to supervened, exhaustions and pending allows to estimate the productivity of the judicial offices in comparison to the justice demand. In the centennial oscillation of the civil procedures of cognition (and particularly of the relative quotients for 100.000 inhabitants), both in first degree and appeals, a growth is established, especially in the last twenty-thirty years, of supervened and exhausted procedures, and still more of those leaning that among the 1991/2000 decade and the average value of the last seven years go over the doubling. The average life of the civil procedures in every degree of judgment that on the contrary has gone growing since 1881 to today, even though with occasional lowering events. The civil procedures of cognition have reached by now the average duration of 3.000 days, and this means around eight years of waiting for the definitive sentence
