La industria del cómic en España: radiografía de ¿un mito o una realidad?
2011
In spite of the importance of figures referred to published titles, or number of copies printed, which help to set publishing strategies and to really know the comic situation in Spain, there are no liable data. We are giving in this article, some enlightening data along with some explanations related to the evolution of the market from 2001 to 2009. The different titles are grouped considering the place they come from (Europe, Asia, United States…), along with their format (album, book, magazine, comic-book…). Using all this information, we can deduce evolution lines, tendencies, futures perspectives in an industry that, despite its precariousness, is facing an increasing number of copies …
Iterated Conditionals, Trivalent Logics, and Conditional Random Quantities
2022
We consider some notions of iterated conditionals by checking the validity of some desirable basic logical and probabilistic properties, which are valid for simple conditionals. We consider de Finetti’s notion of conditional as a three-valued object and as a conditional random quantity in the betting framework. We recall the notions of conjunction and disjunction among conditionals in selected trivalent logics. Then, we analyze the two notions of iterated conditional introduced by Calabrese and de Finetti, respectively. We show that the compound probability theorem and other basic properties are not preserved by these objects, by also computing some probability propagation rules. Then, for …
On compound and iterated conditionals
2021
We illustrate the notions of compound and iterated conditionals introduced, in recent papers, as suitable conditional random quantities, in the framework of coherence. We motivate our definitions by examining some concrete examples. Our logical operations among conditional events satisfy the basic probabilistic properties valid for unconditional events. We show that some, intuitively acceptable, compound sentences on conditionals can be analyzed in a rigorous way in terms of suitable iterated conditionals. We discuss the Import-Export principle, which is not valid in our approach, by also examining the inference from a material conditional to the associated conditional event. Then, we illus…
