Psychology research on men studies, attractiveness, and partner preferences has evolved from the influence of sociobiological perspectives to the role of interactions in shaping election toward sexual–affective relationships and desire toward different kinds of masculinities. However, there is a scientific gap in how language and communicative acts among women influence the kind of partner they feel attracted to and in the reproduction of relationship double standards, like the myth of the “warrior’s rest” where female attractiveness to “bad boys” is encouraged (...) or supported. Some women imitate “the warrior” behavior of men by choosing dominant traditional masculinities (DTM) to have “fun” with and oppressed traditional masculinities (OTM) for “rest” after the “fun” with DTM—choosing an OTM for a stable relationship, but perhaps without passion, while also feeling attraction toward DTM, a response which perpetuates the chauvinist double standard that the feminist movement has condemned when men behave in this sexist way. Through conducting a qualitative study with communicative daily life stories, this article explores, on the one hand, how language and social interaction among women can lead to the reproduction of the DTM role by women and, on the other hand, also how new alternative masculinities (NAM) offer an alternative by explicitly rejecting, through the language of desire, to be the rest for the female warrior, the second fiddle to any woman. This has the potential to become a highly attractive alternative to DTM. Findings provide new knowledge through the analysis of communicative acts and masculinities evidencing the importance of language uses in the reproduction of the double standards in gender relations and to understand how and why these practices are maintained and which kind of language uses can contribute to preventing them. Implications for research and interventions on preventive socialization of gender violence are discussed. (shrink)

Introduction Hospital delirium is a frequent, serious, costly, and underrecognized acute disorder of attention and cognition. Therefore, the prevention of hospital delirium is not only desirable for patients, caregivers, healthcare professionals, and the health system itself, but also a moral duty. Objective To identify and synthetize the main ethical aspects that arise related to the prevention of hospital delirium in patients 65 years and older. Methods A scoping review was carried out in Embase, Medline, and Web of Science. Articles published (...) in English or Spanish analyzing any pharmacologic, non-pharmacologic, or multicomponent intervention for prevention of delirium in hospitalized patients aged 65 years and over were included. Results Twenty-seven studies were included. Based on the frequency of appearance and the relevance, our findings were organized into three main areas. The first one was related to the principle of nonmaleficence and collected findings about the iatrogenic causes of hospital delirium and the use of restraints systems. The second area analyzed the impact of delirium in patients, families, and healthcare professionals from a relational ethics perspective, and addressed the family presence as a factor to prevent delirium. Finally, the third area is related to the quality of care. Conclusion Prevention of delirium in hospitals is essential to avoid the discomfort and potential clinical complications of patients, as well as the suffering of their relatives, caregivers, and healthcare professionals. Policymakers and healthcare managers are encouraged to make the required efforts to prevent delirium in hospitalized older patients. (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

This paper, we propose a modal logic satisfying minimal requirements for reasoning about diagrams via collection of sets and relations between them, following Harel's proposal. We first give an axiomatics of such a theory and then provide its Kripke semantics. Then we extend previous works of ours in order to obtain a decision procedure based on tableaux for this logic. Beside soundness and completeness of our tableaux, we manage to define a strategy of rule application ensuring termination by extending the (...) usual loop test of modal logic S4 to whole sub-structures of the model being computed.

Trying to overcome Dugundji’s result on uncharacterisability of modal logics by finite logical matrices, Kearns and Ivlev proposed, independently, a characterisation of some modal systems by means of four-valued multivalued truth-functions , as an alternative to Kripke semantics. This constitutes an antecedent of the non-deterministic matrices introduced by Avron and Lev . In this paper we propose a reconstruction of Kearns’s and Ivlev’s results in a uniform way, obtaining an extension to another modal systems. The first part of the paper (...) is devoted to four-valued Nmatrices, including Kearns’s and Ivlev’s. Besides proving with full details Kearns’s results for T, S4 and S5, we also obtain a characterisation of the system B by four-valued Nmatrices with level valuations. Concerning Ivlev’s results, two new modal systems are introduced and char.. (shrink)

Dugundji proved in 1940 that most parts of standard modal systems cannot be characterized by a single finite deterministic matrix. In the eighties, Ivlev proposed a semantics of four-valued non-deterministic matrices (which he called quasi-matrices), in order to characterize a hierarchy of weak modal logics without the necessitation rule. In a previous paper, we extended some systems of Ivlev’s hierarchy, also proposing weaker six-valued systems in which the (T) axiom was replaced by the deontic (D) axiom. In this paper, we (...) propose even weaker systems, by eliminating both axioms, which are characterized by eight-valued non-deterministic matrices. In addition, we prove completeness for those new systems. It is natural to ask if a characterization by finite ordinary (deterministic) logical matrices would be possible for all those Ivlev-like systems. We will show that finite deterministic matrices do not characterize any of them. (shrink)

This book looks at the ways in which conditionals, an integral part of philosophy and logic, can be of practical use in computer programming. It analyzes the different types of conditionals, including their applications and potential problems. Other topics include defeasible logics, the Ramsey test, and a unified view of consequence relation and belief revision. Its implications will be of interest to researchers in logic, philosophy, and computer science, particularly artificial intelligence.

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation World Championships held in Kazan, Budapest, and Gwangju. The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results,1 including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers were (...) located primarily in the first or second positions of the freestyle relay. The most successful gender strategy for the 4 × 100 m freestyle and for the 4 × 100 m medley relays was the order male-male-female-female, although no statistical differences were found for the medley relays. In the 4 × 100 m freestyle, the second and third relay legs had a statistical effect on the total relay time, whereas in the 4 × 100 m medley, all four relay legs had a statistical effect on the final performance, the weight of the four strokes being different in heats with respect to the final round. Also, a later position of the first female swimmer or the consecutive position of two female swimmers in the team order significantly affected the relay performance in specific events. Mixed relay events appeared to present specific strategies in comparison to traditional male- or female-only relay lineups. (shrink)

Una aportación importante de Tocqueville a la sociología de la familia es haber mostrado la ligazón existente entre la estructura familiar y la organización social, así como su análisis de las dinámicas psico-políticas del emergente ideal de familia democrática. Sin embargo, el humanismo cívico de Tocqueville se estrella ante la “cuestión de la mujer”. Su defensa de la división sexual del trabajo como funcional para el sistema social o, en su terminología, para el orden moral, fuente y principio del orden (...) social, aprisiona a las mujeres entre los muros de sus hogares y les priva la posibilidad de convertirse en seres completos, es decir, les niega la ciudadanía. Así, el republicanismo tocquevilleano hay que leerlo en masculino: el poder está en manos de los varones y las mujeres son la total otredad, permanecen en la sombra de la democracia, junto a los “no blancos” y los pobres.

In this note, an error in the axiomatization of Ivlev’s modal system Sa+ which we inadvertedly reproduced in our paper “Finite non-deterministic semantics for some modal systems”, is fixed. Additionally, some axioms proposed in were slightly modified. All the technical results in which depend on the previous axiomatization were also fixed. Finally, the discussion about decidability of the level valuation semantics initiated in is taken up. The error in Ivlev’s axiomatization was originally pointed out by H. Omori and D. Skurt (...) in the paper “More modal semantics without possible worlds”, where an alternative solution was proposed. (shrink)

ABSTRACT We consider the question of the complete axiomatization of a relative modal logic with composition and intersection.

1. A. Heyting (1930) introduced an intermediate logic whose semantics is based on a pair of states (‘here’ and ‘there’). This logic was axiomatized by Hosoi (1966), using the sequence of intermedia...
