Multivariate Nonparametric Tests
2004
Multivariate nonparametric statistical tests of hypotheses are described for the one-sample location problem, the several-sample location problem and the problem of testing independence between pairs of vectors. These methods are based on affine-invariant spatial sign and spatial rank vectors. They provide affine-invariant multivariate generalizations of the univariate sign test, signed-rank test, Wilcoxon rank sum test, Kruskal–Wallis test, and the Kendall and Spearman correlation tests. While the emphasis is on tests of hypotheses, certain references to associated affine-equivariant estimators are included. Pitman asymptotic efficiencies demonstrate the excellent performance of these meth…
Flexible latent trait aggregation to analyze employability after the Ph.D. in Italy
2015
The analysis of satisfaction, employability and economic perspectives after the Ph.D. in Italy has not received adequate attention in the past, especially in terms of comparison among universities. To analyze these aspects, in this paper we consider data from the survey ‘Statistica in TEma di Laureati e LAvoro’ on doctors who achieved the title on 2007, 2008 and 2009 [CILEA, Laureati STELLA, indagine occupazionale post-dottorato, dottori di ricerca 2007–2008, Tech. Rep., CILEA, Segrate, 2010; CILEA,Laureati STELLA, indagine occupazionale post-dottorato, dottori di ricerca 2008–2009, Tech. Rep., CILEA, Segrate, 2011]. To deal with the complex, multidimensional nature of the concept, we propo…
Assessing local differences between the spatio-temporal second-order structure of two point patterns occurring on the same linear network
2021
Abstract We introduce Local Indicators of Spatio-Temporal Association (LISTA) functions on linear networks and use them to build a statistical test for local second-order structure. This allows to identify differences in the spatio-temporal clustering behaviour of two point patterns, a point pattern of interest and a background one, both occurring on the same linear network. We assess the performance of the testing procedure for local second-order structure through simulation studies under a variety of scenarios that also account for different generating point processes. We show that the proposed local test is able to correctly identify the spatio-temporal difference in the local second-ord…

A MULTISTAGE DECISION MODEL FOR THE OPTIMAL ISSUANCE OF SOVEREIGN DEBT UNDER ESA95
2014
The aim of this paper is to develop a stochastic programming model for the optimal composition of debt portfolios. Such a prob- lem has recently acquired a more and more major interest, being the indebtedness of many countries quite worrying. We propose a stochastic programming model where the decision maker desires to minimize a certain cost function while bounding the interest rate risk. Our analysis focus mainly on the cost function ESA95, which is a methodology developed by the European System of Accounts to gauge the cost of servicing the debt. The model is implemented under two financing strategies, one as- sumes the government cannot resort to budget surplus to pay interest expenses,…
Stochastic Control Problems
2003
The general theory of stochastic processes originated in the fundamental works of A. N. Kolmogorov and A. Ya. Khincin at the beginning of the 1930s. Kolmogorov, 1938 gave a systematic and rigorous construction of the theory of stochastic processes without aftereffects or, as it is customary to say nowadays, Markov processes. In a number of works, Khincin created the principles of the theory of so-called stationary processes.
The Strategic Scorecards: An Instrumentation of the Strategic Management Accounting. Exploration of a Concept, Instrumentation and Results from a Fre…
2003
I describe in this study a generic model of strategic management accounting instrumentation: the strategic scorecards. In order to build this generic model, I review in the existing literature the concepts of Strategic Control and Strategic Management Accounting (SMA). I present the characteristics of these concepts and analyse the reasons why they emerged. I show how the strategic scorecards are an instrumentation of the SMA in studying the most widely known and esteemed scorecards: the Balanced Scorecards (Kaplan & Norton, 1996) and Skandia's Navigator (Edvinsson & Malone, 1997). I then clarify the outlines for a generic model of strategic scorecard and disclose an "a priori" typology of …
Integrating Experiences: Palermo Mediterranean Gateway City. Identity and Innovation
2019
Metropolitan transformations of the Palermo as a Mediterranean city, guided by envisioning it as a ‘fluid’ gateway city, have been seen as an example for the planning of other such cities in Italy and Europe. The 2025 strategic vision for Palermo was inspired by three key components: (i) the relevance of Palermo as ‘hub territory’ in European level concerns in territorial and infrastructure development policies; (ii) the urban and regional experience with the concept ‘fluid city’ (envisioning the city as a portal and place of interaction and exchanges, not just in terms of goods and people); and (iii) new metropolitan vision produced by new regional and national legislation on metropolitan …
An Approximate Technique for Dynamic Elastic-Plastic Analysis
1994
The possibility of obtaining an approximate sufficiently reliable response for elasticplastic discretized structures subjected to dynamic load (kinematical and/or mechanical), with alow computational effort, has been considered. A suitable technique to this effect comes from the form of the dynamic influence matrix of imposed plastic strains on self-stresses, which is shaped by adding up a sparse time-dependent matrix and a block diagonal time-independent matrix (which is the sum of two block diagonal matrices). Several cases of practical interest have been studied, among these cases a special one where all the degrees-of-freedom are dynamic. The technique is compared to other approximate t…
