A distribution curves comparison approach to analyze the university moving students performance
2018
Da qualche anno anche l’Italia sta assistendo a un flusso migratorio di studenti, che da un povero Sud si dirige verso un più ricco Nord. Se un tempo la migrazione avveniva nel momento di cercare lavoro, adesso questa è anticipata da studenti che ritengono di avere meggiore successo se conseguono il titolo al Nord. L’obiettivo di questo studio è verificare la sensazione empirica secondo la quale in realtà gli studenti che restano per iscriversi alla Laurea Magistrale hanno un percorso simile rispetto a quelli che si iscrivono a un percorso magistrale del Nord. Considerate diverse misure di performance, e svolto i confronti attraverso una nuova procedura di raffronto tra curve di distribuzio…
Le periferie palermitane: percorsi per rinnovare il passato e tutelare il futuro
2007
Le dinamiche strutturali cui sono soggette le città meridionali tendono a configurare spazi di vita svantaggiati dove la tradizionale dicotomia centro/periferia è data più che dalla distanza fisica da un centro da una, ben più profonda, distanza sociale. Si sta conducendo una sperimentazione didattica sul tema della riqualificazione delle periferie urbane di Palermo assumendo come campo di applicazione contesti locali che presentano caratteri morfologici e sociali abbastanza diversificati tali da offrire un quadro esaustivo delle diverse forme che la marginalità assume nel sistema urbano. La sperimentazione ha interessato le aree del fiume Oreto e i quartieri Zen, Borgo Nuovo e Malaspina, c…
Battery- and Petrol-Powered Chainsaws: An Investigation of Productivity in Conifer Thinning
2023
In recent years, battery technology has been greatly improved and some types of battery chainsaws are currently comparable with light-type petrol machines, suggesting their possible introduction into forest operations. In this context, the aim of this study was to test and compare the performance, in a Douglas-fir thinning, of two chainsaws similar in terms of weight and power, the Stihl MS 220 CB battery-powered saw and the Stihl MS 201 CM petrol-powered saw, measuring the working times and calculating the productivities. The results showed that, within a working day (about 6 h gross time), an average of 15 trees of 0.56 m3 was felled in each area. No statistically significant differences …
Improved pairwise comparison transitivity using strategically selected reduced information
2021
To judge the mutual relationship among elements, pairwise comparisons (PC) are widely used in decision modelling. PC is especially useful when the involved elements are intangible. Frequently, the number of elements to be compared may be very large. When dealing with n elements, the number of PCs is, under the reciprocity hypothesis, n(n − 1)/2. PCs are compiled in so-called pairwise comparison matrices (PCM). In the presence of missing entries due to uncertainty or lack of information, decision-making must be performed from the available incomplete information. Making all the comparisons in the complete case may be tedious, strenuous and time-consuming for the actors, may blur the body of …
Hyvinvoinnin teoriat hyvinvoinnin edistämisessä ja poliittisessa päätöksenteossa
2020
Well-being in theory, practice and political decision-making. The concept of well-being is vitally important from many perspectives. We all care about well-being at the personal level. The concept is very much used in politics, welfare services and in social policy. Indisputably, one of the very basic tasks of public administration is to promote the well-being of the citizens. However, there is a lot of conceptual confusion in both political and academic discussions on well-being. For instance, there is no consensus on how should it be understood theoretically or measured in practice. In this article, an interdisciplinary group of researchers brings clarity to urgent theoretical and concept…
Le istituzioni, la politica e la legislazione negli articoli de «La Croce di Savoia»
2008
The journal «La Croce di Savoia» has been considered for a long time a source of great interest in the historiography on Francesco Ferrara for the particular historical circumstances in which it was published and for the first-rank role economic ideas had among the contents of its articles. Public finance,commercial policy and custom duties reform are among its most recurring topics, together with a wider range of topics of discussion such as: the institutions, their organization and their functioning; the political action of States and of political parties; the legislation over the judicial organization and over local authorities. The essay focuses on the writings pointing out the economic…

Nadrzednym przesłaniem jest tutaj teza o uniwersalności języka matematyki. Autor zachęca czytelnika do zapoznania się z metodami taksonomicznymi wykazując ich zalety utylitarne.
Oscillation of Second-Order Neutral Differential Equations
2013
Author's version of an article in the journal: Funkcialaj Ekvacioj. Also available from the publisher at: http://www.math.kobe-u.ac.jp/~fe/ We study oscillatory behavior of a class of second-order neutral differential equations relating oscillation of these equations to existence of positive solutions to associated first-order functional differential inequalities. Our assumptions allow applications to differential equations with both delayed and advanced arguments, and not only. New theorems complement and improve a number of results reported in the literature. Two illustrative examples are provided.
