Although many clustering procedures aim to construct an optimal partition of objects or, sometimes, of variables, there are other methods, called block clustering methods, which consider simultaneously the two sets and organize the data into homogeneous blocks. This kind of methods has practical importance in a wide of variety of applications such as text and market basket data analysis. Typica...

Phil Dowe begins Physical Causation by outlining his metaphilosophical stance, distinguishing between the task of analysing our concept of causation, and the task of offering an “empirical analysis” of “what causation in fact is in the actual world” (p.3). Dowe’s energies are to be devoted to the latter task, although he regards the former as also legitimate. Thus he is not restricted by what w...

2A possible drawback of the ordinary correlation coefficient ρ for two real random variables X and Y is that zero correlation does not imply independence. In this paper we introduce a new correlation coefficient ρ∗ which assumes values between zero and one, equalling zero iff the two variables are independent and equalling one iff the two variables are linearly related. The coefficients ρ∗ and ...

We construct a family of balanced signature pseudo-Riemannian manifolds, which arise as hypersurfaces in flat space, that are curvature homogeneous, that are modeled on a symmetric space, and that are not locally homogeneous.

Sustainable development is perceived as a socioeconomic system focused on meeting human needs while making long-term progress, with the end goal of ensuring well-being and improving quality life.
