The semantical structures called T×W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, ℒO, which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator ⋄. However, these structures are also suitable for interpreting an extended language, ℒSO, containing a further possibility operator ⋄s which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history ‘simultaneity’ operator. In the present paper we provide (...) an infinite set of axioms in ℒSO, which is shown to be strongly complete forT ×W-validity. Von Kutschera (1997) contains a finite axiomatization of T×W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions. (shrink)

Il presente lavoro può essere letto come un manuale di metodologia lessicografica nella documentazione linguistica nell'opera di Tommaso d'Aquino e come saggio ermeneutico sul concetto tommasiano di comunicazione come sistematica riflessione metafisica sull'atto di comunicare.

In the context of a wider investigation into Christianity as dialogue with non-Christians, and following up on a study of the approach of Thomas Aquinas through «demonstrative or probable reasons», the present study examines the approach of Francis of Assisi, who went off to preach to the Sultan and ordered his friars to give witness to the Gospel without resorting to discussions or conflicts, and that of Bonaventure, who, like Paul in the First Letter to the Corinthians, insisted on the (...) power of the signs of God and of his Word.

L'A. présente un ouvrage écrit par le Père Roberto Busa et paru récemment : Richerche lessicologiche. Il s'agit d'un travail lexicologique sur le vocabulaire employé par saint Thomas d'Aquin pour élaborer son système ontologique. L'A. dénombre et décrit les nouvelles acquisitions linguistico-ontologiques que ce travail a permis dans le champ du thomisme. Elles sont au nombre de trois : l'hétérogénéité sémantique des mots, la segmentation morphothématique des lemmes, les terminaisons latines.

The modern concept of 'dialogue' among persons and groups of different religions or 'world-views' is the fruit of interaction between Christian tradition and the technique of dialogue in Greek philosophy. Dialogue in general requires a classification of those in dialogue , a prototype and an archetype of mediation , a teleotype or final objective , a procedural type , and a representation of spacial logic . This article examines especially the Thomistic approach, through demonstrative and probable reasons.

In this thesis I defend and pursue that line about the foundations of probability theory which has come to be known as "the logicist view about probability", and, in particular, the shape which it took in Carnap's Inductive Logic. ;Most philosophers who now deal with probability theory claim that Carnap's program of Inductive Logic has failed. The main aim of my thesis is to show that this judgment is based on a fundamental misunderstanding about the nature and the aim of (...) inductive logic. To that end, I follow, in chapter 1, the events in the history of probability, logic and mathematics which led to choosing certain requirements as the requirements which any theory about the foundations of probability must fulfill in order to be acceptable. ;In chapter 2 I explain how Carnap's inductive logic fulfills those requirements and how the method it uses to give foundations to probability theory can also be used to solve another major problem about probability, namely, the problem of statistical inference. ;Chapter 3 shows how the ideas explained in chapter 2 were developed, formally, by Carnap, and how Carnap's program can be continued in a particular case, that of reasoning by analogy. ;Finally, in chapter 4, I attempt to show that subjectivism about probability theory, the rival theory to Carnap's logicism, does not succeed in meeting the most basic requirement for the acceptability of any theory about the foundations of probability.

On the historiographic plane, the confrontation between the texts of Bonaventure and of Thomas Aquinas regarding the structure of human knowledge, reveals common features and divergent ones. Both are, moreover, «scholastics» in the elaboration of the sources, in so far as they do not select only some data of tradition , but seek through various paths to assume and to synthetise coherently the whole tradition known to them. Bonaventure has followed the path of extrapollation of the single data from their (...) original context and of their insertion into a schema altogether traditional as to the content, but altogether new as for the structure. Thomas, on the contrary, has chosen the way of composition of the data through the concordance and the hierarchy of the schema, giving clearly the epistemological primacy to the Aristotelian system, but without showing himself ever fully satisfied with the schemata obtained. In articulating philosophy and theology Thomas et Bonaventure share the paradigm of the «double in parallel», bringing it perhaps to the extreme rigour, though with different nuances: Thomas by showing the natural basis of the supernatural perfection, and Bonaventure by showing the necessity and the natural impossibility of such perfectioning.

Ponto de partida do artigo é a consideração de que o problema da relação entre Filosofia e Espiritualidade, ainda que problemático, é filosoficamente pensável e pode ser historicamente reconstruído. Com efeito, o artigo mostra de que modo o problema foi objecto de uma sistematização paradoxal, ainda que coerente e exemplar, por parte de S. Boaventura, cuja reflexão, tematizando a espiritualidade minorítica, radica em S. Francisco de Assis, ainda que também através da mediação de Santo António de Lisboa. Segundo S. Boaventura, (...) Deus manifesta-se de forma natural no livro da natureza mediante o Verbo incriado, cognoscível mediante a razão natural na ciência natural, que é a Filosofia; e revela-se sobrenaturalmente no livro da Escritura mediante o Verbo incarnado, cognoscível mediante a razão iluminada pela fé na ciência sobrenatural, que é a Teologia; mas também se comunica pessoalmente e concretamente no coração dos crentes mediante o Verbo inspirado, ou seja, o Cristo feito presente pelo Espírito Santo na "vida espiritual", num processo ascético-místico, cujo primeiro estádio é, paradoxalmente, a própria Filosofia, aqui entendida como a busca da sabedoria através das virtudes cardeais. Por outro lado, o artigo mostra também como o próprio paradigma da reedificação interior através das virtudes parece estabelecer um vínculo entre S. Francisco de Assis e Santo António de Lisboa, bem como entre os dois e S. Boaventura, o qual, hipotiza o autor do artigo, não só leu alguma coisa dos Sermões de Santo António, como deles retirou elementos para as suas reflexões mais maduras. /// The starting point of this article is the consideration that the problem of the relation between Philosophy and Spirituality, even if problematic, can be philosophically thought and historically reconstructed. In effect, the article shows how this problem was object of a paradoxical systematization, coherent and exemplar, on the part of Saint Bonaventure, whose reflection, typical of the Franciscan spirituality, is rooted in Saint Francis of Assisi, even if also through the mediation of Saint Anthony of Lisbon. According to Saint Bonaventure, God reveals Godself naturally in the Book of nature by means of the uncreated Logos, knowable through natural reason in the natural science, which is Philosophy; and God reveals Godself supernaturally in the Book of Scripture by means of the incarnated Logos knowable by means of reason illuminated by faith in the supernatural science, which is Theology; but God also communicates Godself personally and concretely in the hearts of the believers by means of the inspired Logos, i.e., the Christ made present through the Holy Spirit in the "spiritual life", in an ascetic-mystical process, whose first stage is, paradoxically, Philosophy itself, here understood as the search for Wisdom through the cardinal virtues. On the other hand, the article also shows how the paradigm of the interior edification through the virtues seems to establish a link between Saint Francis of Assisi and Saint Anthony of Lisbon, as well as between the two and Saint Bonaventure, who, according to the article, not only has read something of Saint Anthony's Sermons, but also has taken something from them for his mature reflexions.

The semantical structures called T x W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, $[Unrepresented Character]_{o}$ , which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator ◇. However, these structures are also suitable for interpreting an extended language, $[Unrepresented Character]_{so}$ , containing a further possibility operator $\lozenge^{s}$ which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history 'simultaneity' operator. (...) In the present paper we provide an infinite set of axioms in $[Unrepresented Character]_{so}$ , which is shown to be strongly complete for T x W-validity. Von Kutschera (1997) contains a finite axiomatization of T x W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions. (shrink)

The λ-continuum of inductive methods was derived from an assumption, called λ-condition, which says that the probability of finding an individual having property $x_{j}$ depends only on the number of observed individuals having property $x_{j}$ and on the total number of observed individuals. So, according to that assumption, all individuals with properties which are different from $x_{j}$ have equal weight with respect to that probability and, in particular, it does not matter whether any individual was observed having some property similar (...) to $x_{j}$ (the most complete proof of this result is presented in Carnap, 1980). The problem thus remained open to find some general condition, weaker than the λ-condition, which would allow for the derivation of probability functions which might be sensitive to similarity. Carnap himself suggested a weakening of the λ-condition which might allow for similarity sensitive probability functions (Carnap, 1980, p. 45) but he did not find the family of probability functions derivable from that principle. The aim of this paper is to present the family of probability functions derivable from Carnap's suggestion and to show how it is derived. In Section 1 the general problem of analogy by similarity in inductive logic is presented, Section 2 outlines the notation and the conceptual background involved in the proof, Section 3 gives the proof, Section 4 discusses Carnap's principle and the result, Section 5 is a brief review of the solutions which have previously been proposed.

Il problema dell'induzione è tra i più dibattuti in filosofia della scienza. Il mio tentativo in questo scritto sarà di mostrare come un'indagine sull'induzione possa contribuire a chiarire i termini del dibattito intorno a relativismo, pluralismo culturale e democrazia.

This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

Nella filosofia vi sono dimensioni di tipo pubblico e politico e dimensioni che sono essenzialmente di carattere individuale. C'è qualcosa di simile a un confine tra questi due piani? È in qualche modo individuabile? Quali sono i limiti dell'influenza sociale sulla mente del singolo? Faccio riferimento in questo scritto alle opere di Piaget, Nietzsche, Foucault, Elias. I principali strumenti concettuali che utilizzo sono connessi con la funzione dell'esperienza e dell'induzione.

Introduction: Novel coronavirus is having a devastating psychological impact on patients, especially patients with cancer. This work aims to evaluate mood disorders of cancer patients undergoing radiation therapy during COVID-19 in comparison with cancer patients who underwent radiation therapy in 2019.Materials and Methods: We included all the patients undergoing radiation therapy at our department in two-time points and during the COVID-19 outbreak. All the patients were asked to fulfill a validated questionnaire, the Symptom Distress thermometer, and the Beck Depression Inventory (...) v.2. We took into account the COVID-19 outbreak and also sex, age, week of radiation treatment, and disease.Results: We included 458 patients, with a median age of 64 years. STAI-Y1 median score was 40, whereas the median score of SDT was five and BDI-2 median score was 11. STAI-Y1, SDT, and BDI-2 were significantly correlated with the COVID-19 outbreak, sex, week of treatment, and disease.Conclusions: The prevalence of mood disorders in patients undergoing radiation therapy is higher than expected and even higher during the COVID-19 outbreak. These measurements could be useful as a baseline to start medical humanities programs to decrease these scores. (shrink)

Tommaso si e confrontato spesso con il tema del fine dell'uomo: ampie sezioni delle sue opere vi sono espressamente dedicate e altre ne sono l'implicita trattazione. La presente ricerca vuole introdursi all'opera di Tommaso d'Aquino non tanto evocando gli spettri di polemiche solo posteriori sul soprannaturale, quanto invece gettando uno sguardo al tempo in cui e vissuto, il XIII secolo, ed ad un luogo caratteristico nel quale egli ha studiato e insegnato: l'universita di Parigi. Ne viene fuori una figura in (...) profonda osmosi con le tensioni spirituali della sua epoca e preoccupato di esprimere la perennita della fede. Alfonso Valsecchi, 1971, ha conseguito licenza e dottorato presso la Pontificia Universita Gregoriana. (shrink)

Research Ethics Committees have the responsibility to protect the participants involved in researches and to guarantee the ethical behavior of researchers. In some institutions, such committees also review scientific projects of non-pharmaceutical areas, Public Health and Health Economics. Within this framework, the article analyzes what it means to be part of a Research Ethics Committee in a hospital or university based on personal experience as a community representative. By means of the convenience sampling technique, implemented in four Colombian cities that (...) have GCP-certified committees by INVIMA –National Institute for the Control of Medications and Food–, and by means of content analysis, based on fixed and emergent categories; the experience, perception, participation, representation, and ethical aspects are described as well as the learning process and personal contributions. Findings prove that representatives interviewed have been benefited by learning clinic and epidemiological aspects without necessarily being “experts in the community”. However, they seem not to recognize clearly the population they represent, which might lead these communities to being affected by certain particular studies. The article suggests to work on the minimal common elements that a community representative should possess to appropriately protect participants. (shrink)
