The prepositional calculiC n , 1 n introduced by N.C.A. da Costa constitute special kinds of paraconsistent logics. A question which remained open for some time concerned whether it was possible to obtain a Lindenbaum''s algebra forC n . C. Mortensen settled the problem, proving that no equivalence relation forC n . determines a non-trivial quotient algebra.The concept of da Costa algebra, which reflects most of the logical properties ofC n , as well as the concept of paraconsistent closure system, (...) are introduced in this paper.

We investigate the pair-splitting number $\germ{s}_{pair}$ which is a variation of splitting number, pair-reaping number $\germ{r}_{pair}$ which is a variation of reaping number and cardinal invariants of ideals on ω. We also study cardinal invariants of F σ ideals and their upper bounds and lower bounds. As an application, we answer a question of S. Solecki by showing that the ideal of finitely chromatic graphs is not locally Katětov-minimal among ideals not satisfying Fatou's lemma.

We address some phenomena about the interaction between lower semicontinuous submeasures on $${\mathbb {N}}$$ N and $$F_{\sigma }$$ F σ ideals. We analyze the pathology degree of a submeasure and present a method to construct pathological $$F_{\sigma }$$ F σ ideals. We give a partial answers to the question of whether every nonpathological tall $$F_{\sigma }$$ F σ ideal is Katětov above the random ideal or at least has a Borel selector. Finally, we show a representation of nonpathological $$F_{\sigma }$$ (...) F σ ideals using sequences in Banach spaces. (shrink)

La violencia en México, específicamente en algunos estados de la República mexicana en donde la población se enfrenta a situaciones de peligro, tiene como una de tantas consecuencias la ausencia de personal médico que se desempeñe como profesional y proporcione servicios de salud en estas zonas rurales. En este sentido, es de considerar que la asignación de recursos humanos en salud es fundamental para el funcionamiento de un sistema eficiente y observar las causas por las que médicos que desde el (...) servicio social hasta el desempeño de su especialidad no consideran trabajar en lugares en donde se sienten vulnerables. En este proceso, es importante visibilizar los cuestionamientos éticos que pueden surgir por lo que este trabajo pretende dar importancia al tema de la exposición de circunstancias, hechos y cifras dentro de esta problemática y plantear las cuestiones normativas pertinentes dentro de este contexto.

El Espacio Europeo de Educación Superior (EEES) establece que el aprendizaje debe estar centrado en el estudiante. Partiendo de este enunciado, el artículo explica cómo la gamificación puede ser una técnica pedagógica que propicie el ansiado cambio en la docencia universitaria hacia donde marca el EEES. Este trabajo presenta el diseño de una metodología de gamificación sencilla y fácil de implementar en un Grado de Ingeniería utilizando Kahoot! como herramienta y su evolución a lo largo de tres cursos académicos. Los (...) resultados indican que los alumnos ven más atractiva la asignatura, aumenta el seguimiento y mejoran sus resultados académicos. (shrink)

While there is abundant research on innovations, we know little about why and when the commercialization of highly contested innovations, such as genetically modified (GM) crops, is approved by governments. In this paper, we argue that governments' decision to approve the commercialization of GM crops is influenced by heuristics based on the decisions of other governments with which they have greater trade, the gap between country performance and aspiration, and governments' prior decisions on GM crops field trials. We further propose (...) that the effect of these heuristics weakens when the government operates in countries with higher governance quality. Using data on approval of GM crop commercialization between 1991 and 2016, we found support for these arguments and suggest the joint effects of heuristics based on the decisions of trade partners and governance quality on governments' approval of GM crop commercialization.

The COVID-19 pandemic and restrictions imposed to stop its advance have affected the entire population. Children living with difficulties or in vulnerable situations prior to the pandemic might have suffered an even greater impact. This present study examines the psychological impact of quarantine on children and adolescents exposed to intimate partner violence against their mothers. Participants were 185 mothers who reported 269 children, as well as 108 children who self-reported. An emotional and behavioral checklist was administered to both mothers and (...) children throughout confinement. Results show mothers observed changes in their children’s psychological state. Children, in turn, reported an increase in different variables. Mothers reported a higher percentage of overall increase for both general and severe symptoms than their children. Differences were found by sex and age. Future research with similar population groups is necessary to establish the support and intervention children require in similar contexts, as well as to clarify possible causes of differences found by age and sex.

Las obras históricas escritas en la época de la Reforma y el Segundo Imperio Mexicano, así como su discusión en la prensa, son importantes para la construcción del Estado mexicano moderno. Se analiza la recepción que tuvo en los periódicos un corpus de obras históricas representativas escritas por liberales y conservadores, publicadas entre 1856 y 1874.

The Zapatista Indigenous Movement from Chiapas, Mexico is an example of the anthropological dynamics between the visible and the invisible in Western culture and the possible revolution of perceiving reality as such since they had to cover their faces with masks in their rebel anti-system movement in order to be considered as having the same dignity as other human beings: they performed a revolutionary act that changed the symbolic order of the visible by the public exhibition of their colonial submission. (...) The mask gave them a face, disrupting the order of the visible with uncanny faces. In this article, a nondual model is proposed to capture the inessential ground of the given composed of endless perspectives in continuous transformation by the generation of ontological novelty: an open cognitive horizon of symbolically empty points of view irreducible to one perspective. For Krishnamurti, the revolutionary act is to see without an image in order to phenomenologically attend to things as they are beyond the known and the unknown such as Stilinovi? and Malevich pursued the dissolution of symbolic representations through art for the transformation of human reality.

Mexico's pandemic management and the absence of measures have been harshly criticized as being disproportionate. This paper examines whether the proportionality principle was properly applied to Mexico's COVID-19 response and outlines three reasons against such an endeavor, namely (i) the content of “proportionate measures” remained insufficiently well defined, (ii) there were yet fundamental rights conflicts to resolve, and (iii) the situation was moreover characterized by epistemic uncertainty.

Introduction: Congruence, understood as the agreement between the patient's preferred place of death and their actual place of death, is emerging as one of the main variables indicating the quality of end-of-life care. The aim of this research was to conduct a systematic literature review on levels and determinants of congruence in palliative patients over the period 2010–2021.Method: A systematic review of the literature in the databases of PubMed, Scopus, Web of Science, PsycINFO, CINAHL, Cuiden, the Cochrane Library, CSIC Indexes, (...) and IBECS. Information was extracted on research characteristics, congruence, and associated factors.Results: A total of 30 studies were identified, mainly of retrospective observational design. The congruence values varied substantially between the various studies, ranging from 21 to 100%. The main predictors of congruence include illness-related factors, individual factors, and environmental factors.Conclusion: This review, in comparison with previous studies, shows that treatment-related factors such as physical pain control, marital status, having a non-working relative, age, discussing preferred place of death with a healthcare professional, and caregiver's preference have been associated with higher levels of congruence. Depending on the study, other factors have been associated with either higher or lower congruence, such as the patient's diagnosis, gender, or place of residence. This information is useful for designing interventions aimed towards greater congruence at the end of life. (shrink)

Cherchant à refonder l’édifice euclidien, Leibniz a formulé une Caractéristique géométrique qui annonce les concepts géneraux de la théorie des ensembles. Dans ce cadre, il a pu en particulier formaliser sa conception du continu. L’intérêt du Pacidius Philalethi (1676) est de montrer qu’en choisissant la conception intensionnelle du continu -position qu’il ne dementira jamais- il sélectionne parmi les images duales celle dont se déduit le changement qualitatif, base d’une philosophie naturelle qui soutiendra encore la dynamique ultérieure. Une tâche se dessine (...) maintenant, soit déduire la nécessité d’un mouvement universei et infiniment varié à partir de ses conditions topologiques.We know that Leibniz intended to bring new foundations to the euclidean geometry and he has according to this view formulate a Characteristica geometrica which announces few general concepts of set theory. Parlicularly he tried to formalise his conception of continuity. Before the main interest of the Pacidius Philalethi (1676) is here: showing us that Leibniz when he chooses an intensional conception of continuity he chooses in the same time the dual image from which be can deduce the qualitative variation. We reckon again these conception at the grounds of his later philosophy of nature. But now we have to follow Leibniz demostrating how universal and infinite variations flow from its topological conditions. (shrink)

The objectives of the present study were to adapt a grief intervention program to family caregivers of patients with dementia, and assess its effectiveness in improving the symptoms of grief and other health-related variables. The intervention was based on Shear and Bloom's grief intervention program, with the necessary adaptations for use in the grieving process for a family member's illness. A total of 52 family caregivers of individuals with dementia participated. They were evaluated using a battery of self-report measures assessing (...) grief, overload, resilience, post-traumatic growth, experiential avoidance, health-related quality of life, and benefits of care. The results suggest that the program is effective in improving grief symptoms, caregiver burden, resilience, post-traumatic growth, and quality of life of family caregivers. It is necessary to create and implement interventions targeting caregivers' feelings and manifestations of ambiguous grief, because there is a lack of programs providing an efficient solution for the mental and physical health of caregivers, and because of the human and socioeconomic cost involved in neglecting this group.

O presente artigo tem por finalidade demonstrar que, apesar de não estar expresso no rol das cláusulas pétreas, o macroprincípio da fraternidade jurídica não é passível de ser suprimido do texto constitucional. Ainda que não esteja presente expressamente na parte dogmática da Constituição Federal de 1988, a fraternidade se apresenta de forma implícita em diversos dispositivos normativos fundamentais e expressamente no preâmbulo, trecho inaugural da Lei Fundamental. Desse modo, a pesquisa que ora se apresenta parte do seguinte questionamento: O princípio (...) jurídico da fraternidade pode ser considerado uma cláusula pétrea constitucional? Decisões judiciais recentes e estudos doutrinários contemporâneos no campo das ciências jurídicas evidenciam que, além de estar presente na parte introdutória da Constituição brasileira, também se encontra consubstanciada em diversos dispositivos fundamentais do corpo normativo constitucional. Pretende-se aqui identificar como o princípio da fraternidade jurídica se entrelaça com outros princípios fundamentais presentes no texto dogmático da Constituição da República. A metodologia aplicada a esta pesquisa é qualitativa e bibliográfica ao buscar fontes na doutrina jurídica relacionadas com a fraternidade e os direitos humanos fundamentais. (shrink)
