Pairs of k-step reachability and m-step observability matrices
No full textLet V and W be matrices of size n x pk and qm x n, respectively.
A necessary and sufficient condition is given for the existence of a triple (A,B,C) such that V is a k-step reachability matrix of (A,B) and W an m-step observability matrix of (A,C)

Applying General Impostors Method to the Ferrante Case
No full textElena Ferrante is the nome de plume of an anonymous writer who is highly successful on the international stage and whose success far exceeds that of other products of Italian contemporary literature. In this study we approach Ferrante’s authorship investigation as a verification problem since we cannot be sure whether the real author behind Ferrante’s pseudonym is among the candidates we have considered in previous studies. For this reason, we applied the General Impostors’ (GI) method using the Cosine Delta distance in both a corpus of 150 novels written by 40 authors (39 candidates and Elena Ferrante) and a non-literary corpus of 113 texts signed by 14 different entities (12 authors, a collective author and Elena Ferrante). In the literary corpus Starnone emerged as the most likely author of Ferrante’s novels. Results were quite different in the second case: Starnone was not the only possible author since in many non-literary texts Raja, Martone as well as the E/O publishing house staff and publishers seem to have authorial contributions. The GI method not only confirmed previous results but also improved our knowledge on this case since it provides a measure of the attribution strength

Education, Aspirations and Life Satisfaction
No full textThe idea that expanding work and consumption opportunities always increases people’s wellbeing is well established in economics but finds no support in psychology. Instead, there is evidence in both economics and psychology that people’s life satisfaction depends on how experienced utility compares with expectations of life satisfaction or decision utility. In this paper I suggest that expanding work and consumption opportunities is a good thing for decision utility but may not be so for experienced utility. On this premise, I argue that people may overrate their socioeconomic prospects relative to real life chances and I discuss how systematic frustration over unfulfilled expectations can be connected to people’s educational achievement. I test the model’s predictions on Italian data and find preliminary support for the idea that education and access to stimulating environments may have a perverse impact on life satisfaction. I also find evidence that the latter effect is mediated by factors such as gender and age. Indeed, the model seeks to go beyond the Italian case and provide more general insights into how age/life satisfaction relationships can be modelled and explained.education, opportunities, aspirations, life satisfaction, regret
Order reduction of discrete-time algebraic Riccati equations with singular closed loop matrix
No full textWe study the general discrete-time algebraic Riccati equation and deal with the case where the closed loop matrix corresponding to an arbitrary solution is singular. In this case the extended symplectic pencil associated with the DARE has 0 as a characteristic root and the corresponding spectral deflating subspace gives rise to a subspace where all solutions of the DARE coincide. This allows for a reduction of the original DARE to an equation of smaller size
Profiling Elena Ferrante: a Look Beyond Novels
No full textElena Ferrante represents rather a peculiar editorial and journalistic phenomenon: Today, she enjoys a wide international audience, though, on the other hand, there is surprisingly little scientific literature that discusses her works. Since Elena Ferrante is a pseudonym for an anonymous writer, some investigators have already dealt with the pursuit of her real identity and, at the moment, the main suspects that emerged are Domenico Starnone, Marcella Marmo and Anita Raja. Corpora collected in order to analyze Elena Ferrante's works and compare them with the works of other authors are usually composed of novels, however Marcella Marmo and Anita Raja are not novelists and their works are not ascribed to genres comparable with novels. One of Elena Ferrante's books, La Frantumaglia, is useful to collect corpora of texts of different genres (letters, essays, interviews, etc.) and they might include texts by authors that have never been taken into consideration in research studies based on novelists. Nevertheless, these texts raise specific questions that concern their exploitability in traditional authorship attribution procedures due to their limited size. This study aims at working on a corpus of texts other than novels by means of a machine learning approach, in the frame of methods for authorship attribution and profiling
Roth's similarity theorem and rank minimization in the presence of nonderogatory or semisimple eigenvalues
No full textRoth's similarity theorem on the consistency of Sylvester's matrix equation AX − XA = C can be extended to a theorem on rank minimization if the common eigenvalues of A and B are nonderogatory or semisimple
