In preference aggregation a set of individuals express preferences over a set of alternatives, and these preferences have to be aggregated into a collective preference. When preferences are represented as orders, aggregation procedures are called social welfare functions. Classical results in social choice theory state that it is impossible to aggregate the preferences of a set of individuals under different natural sets of axiomatic conditions. We define a first-order language for social welfare functions and we give a complete axiomatisation for (...) this class, without having the number of individuals or alternatives specified in the language. We are able to express classical axiomatic requirements in our first-order language, giving formal axioms for three classical theorems of preference aggregation by Arrow, by Sen, and by Kirman and Sondermann. We explore to what extent such theorems can be formally derived from our axiomatisations, obtaining positive results for Sen’s Theorem and the Kirman-Sondermann Theorem. For the case of Arrow’s Theorem, which does not apply in the case of infinite societies, we have to resort to fixing the number of individuals with an additional axiom. In the long run, we hope that our approach to formalisation can serve as the basis for a fully automated proof of classical and new theorems in social choice theory. (shrink)

School inclusion embodies an educational philosophy aimed at ensuring that each and every student, regardless of individual characteristics, abilities, personal circumstances, or social conditions, is fully engaged and actively involved in the educational experience. This approach emphasizes diversity as a value and promotes the acceptance and appreciation of individual differences within the school environment. Despite the desirability of inclusive education systems being enshrined in many international and national Declarations and regulations, practical approaches still often lean towards school “integration”, understood as (...) a paradigm of “assimilation”, which involves adapting disabled students to a school structure primarily designed for typical students. This article underscores the essential functions of assessing inclusion policies within individual educational institutions and, more broadly, evaluating mechanisms within the larger educational system to achieve continuous improvement in the real inclusion of all students, dedicating an in-depth analysis to the Italian context. The effective and adequate assessment in this field is challenging and methodological reflection is absolutely indispensable to define shared frameworks for evaluation policies. Building upon the recent OECD framework proposal (2023), this work suggests expanding the set of indicators to provide a more comprehensive and in-depth evaluation of school inclusion policies.

A collection of essays discusses current issues, including spirituality, war, disenchantment, traditions, fascism, and customs, and draws from past experiences that have had a profound impact on the world today.

A collection of essays discusses such topics as the nature of perception, the semiotic links between cognition and language, and iconism, with imaginative fables featuring animal heroes to illustrate the main points.

An erudite and witty collection of Umberto Eco's essays on mass culture from the 1960s through the 1980s, including major pieces which have not been translated into English before. The discussion is framed by opposing characterizations of current intellectuals as apocalyptic and opposed to all mass culture, or as integrated intellectuals, so much a part of mass culture as to be unaware of serving it. Organized in four main parts, "Mass Culture: Apocalypse Postponed," "Mass Media and the Limits of (...) Communication," "The Rise and Fall of Counter-Cultures," and "In Search of Italian Genius," Eco looks at a variety of topics and cultural productions, including the world of Charlie Brown, distinctions between highbrow and lowbrow, the future of literacy, Chinese comic strips, whether countercultures exist, Fellini's Ginger and Fred, and the Italian genius industry.

The world’s press may have lost interest in the ongoing enquiry into the deep‐rooted corruption in Italian business. But what exactly was going on, and what can be done to improve matters? The writers of this authoritative study are Faculty members of the prestigious Italian Business School, SDA Bocconi, Via F. Bocconi 8, 8‐20136 Milano, where Umberto Lago lectures in Strategy and Roberto Castoldi in Accounting. They both lecture on the Business Policy course at Bocconi University.

As the only book-length treatment of Aquinas's aesthetics available in English, this volume should interest philosophers, medievalists, historians, critics, and ...

We develop an algebraic study of W.S. Cooper’s three-valued propositional logic of ordinary discourse ( $$\mathcal{O}\mathcal{L}$$ O L ). This logic displays a number of unusual features: $$\mathcal{O}\mathcal{L}$$ O L is not weaker but incomparable with classical logic, it is connexive, paraconsistent and contradictory. As a non-structural logic, $$\mathcal{O}\mathcal{L}$$ O L cannot be algebraized by the standard methods. However, we show that $$\mathcal{O}\mathcal{L}$$ O L has an algebraizable structural companion, and determine its equivalent semantics, which turns out to be a (...) finitely-generated discriminator variety. We provide an equational and a twist presentation for this class of algebras, which allow us to compare it with other well-known algebras of non-classical logics. In this way we establish that $$\mathcal{O}\mathcal{L}$$ O L is definitionally equivalent to an expansion of the three-valued logic $${\mathcal {J}}3$$ J 3 of D’Ottaviano and da Costa, itself a schematic extension of paraconsistent Nelson logic.

Irrational debt decisions at the individual level may harm collective welfare. For this reason, regulators are committed to encourage information-based behaviours in order to enhance likelihood of appropriate indebtedness. We analyse, with a diff-in-diff estimator, the Italian case offered by the Legislative Decree that reformed the consumer credit market adopting European Directive 2008/48/ec, and that reinforced the mandatory information acquisition, jointly asked to lenders and borrowers, before granting/receiving consumer credit. By using micro-data on 60.000 consumer credit borrowers, in total, randomly (...) sampled from the most relevant Italian Credit Bureau, our findings support that, in the medium term, the new consumer credit regulation has improved borrowers’ repayment ability, enhancing the quality of credit distribution. Nevertheless, a simplistic ‘better information-better behaviour’ relationship cannot be assured. This success is likely due to conjunct adaptation of behaviours, with shared responsibilities experienced on both the demand and offer side of the consumer credit marketplace. (shrink)

La crisi dello strutturalismo e i confini della semiotica in un volume importante della produzione di Eco. Un libro che trova la sua continuazione ideale in 'Lector in fabula'.

In the course of the long debate on the nature and the classification of signs, from Boethius to Ockham, there are at least three lines of thought: the Stoic heritage, that influences Augustine, Abelard, Francis Bacon; the Aristotelian tradition, stemming from the commentaries on De Interpretatione; the discussion of the grammarians, from Priscian to the Modistae. Modern interpreters are frequently misled by the fact that the various authors regularly used the same terms. Such a homogeneous terminology, however, covers profound theoretical (...) differences. The aim of these essays is to show that the medieval theory of signs does not represent a unique body of semiotic notions: there are diverse and frequently alternative semiotic theories. This book thus represents an attempt to encourage further research on the still unrecognized variety of the semiotic approaches offered by the medieval philosophies of language. (shrink)

"Eco wittily and enchantingly develops themes often touched on in his previous works, but he delves deeper into their complex nature... this collection can be read with pleasure by those unversed in semiotic theory." —Times Literary Supplement.

One is the beloved author of The Name of the Rose, a celebrated scholar, philosopher, and self-declared secularist; the other is a preeminent clergyman and a respected expert on the New Testament. In this intellectually stimulating dialogue, often adversarial but always amicable, these two great men, who stand on opposite sides of the church door, discuss some of the most controversial issues of our day, including the apocalypse, abortion, women in the clergy, and ethics. As we voyage onward into the (...) new millennium, they frame a debate about matters that have already begun to rage, always aware of the gulf between belief and nonbelief that separates them, constantly probing and challenging, but also respectful of the other’s viewpoint. For believers and nonbelievers alike, the result is both edifying and illuminating. “Their correspondence,” writes Professor Harvey Cox in his introduction, “lifts the possibility of intelligent conversation on religion to a new level.”.

We look at extensions (i.e., stronger logics in the same language) of the Belnap–Dunn four-valued logic. We prove the existence of a countable chain of logics that extend the Belnap–Dunn and do not coincide with any of the known extensions (Kleene’s logics, Priest’s logic of paradox). We characterise the reduced algebraic models of these new logics and prove a completeness result for the first and last element of the chain stating that both logics are determined by a single finite logical (...) matrix. We show that the last logic of the chain is not finitely axiomatisable. (shrink)
