Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) (...) logic programs. It turns out that none of the existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle. (shrink)

Normative systems have been advocated as an effective tool to regulate interaction in multi-agent systems. The use of deontic operators and the ability to represent defeasible information are known to be two fundamental ingredients to represent and reason about normative systems. In this paper, after introducing a framework that combines standard deontic logic and non-monotonic logic programming, deontic logic programs (DLP), we tackle the fundamental problem of equivalence between normative systems using a deontic extension of David Pearce’s Equilibrium Logic and (...) its monotonic basis, the logic of Here-and-There. We also show how deontic logic programs can be used to represent and reason about normative systems, and establish a strong connection with input-output logic. (shrink)

This book presents the refereed proceedings of the Sixth European Workshop on Logics in Artificial Intelligence, JELIA '96, held in Evora, Portugal in September/October 1996. The 25 revised full papers included together with three invited papers were selected from 57 submissions. Many relevant aspects of AI logics are addressed. The papers are organized in sections on automated reasoning, modal logics, applications, nonmonotonic reasoning, default logics, logic programming, temporal and spatial logics, and belief revision and paraconsistency.

Esa rareza que llamamos conciencia, lo más misterioso que hay en el universo, procedería de darse en ella la conjunción de dos cosas totalmente distintas: por un lado, el acto de referirse a algo y ese algo a lo cual se refiere. A esta forma de relación es a lo que tradicionalmente se ha denominado “intencionalidad” de la conciencia.

Looking to understand religiosity as a social factor, contributory of constructions of meaning and omnipresent in diverse historical and cultural universes, this article focuses on the ritualistic dimension of religiosity. Adopting as a research problem the religious pilgrimages, take particular note of the shrines as symbolic markers towards the supernatural. This work has a double aim: to carry out a review and critical analysis of the religious pilgrimages and to study the specificity of the pilgrimages to the Shrine of Fatima, (...) located in Portugal. After a brief mention of the dialectic dissidence-coexistence of ancient religious practices in secularized societies, the concepts of worship, rites and sacrifices are revisited. There follows a more in-depth analysis of the theme of pilgrimages to shrines, from the concept and historical review to the particularity of pilgrimages to the Shrine of Fatima, the latter viewed as a geo-symbol of religious tourism in Portugal. The results of a survey of 784 pilgrims to the Shrine of Fátima are presented, focusing on the beliefs, experiences, perceptions, purposes and expectations regarding the pilgrimage, as well as the nature of the requests addressed to the Lady of Fatima and promises fulfilled. Throughout the article the pilgrim character is emphasized, not neglecting the analysis of the active, voluntary and sacrificial behavioral implication as legitimating the benefits already granted or to be granted.

The concepts of “good” and “bad” are associated with right and left space. Individuals tend to associate good things with the side of their dominant hand, where they experience greater motor fluency, and bad things with their nondominant side. This mapping has been shown to be flexible: Changing the relative fluency of the hands, or even observing a change in someone else's motor fluency, results in a reversal of the conceptual mapping, such that good things become associated with the side (...) of the nondominant hand. Yet, based on prior studies, it is unclear whether space–valence associations were determined by the experience of fluent versus disfluent actions, or by the mere expectation of fluency. Here, we tested the role of expected fluency by removing motor execution and perceptual feedback altogether. Participants were asked to imagine themselves performing a psychomotor task with one of their hands impaired, after which their implicit space–valence mapping was measured. After imagining that their right hand was impaired, right-handed participants showed the “good is left” association typical of left-handers. Motor imagery can change people's implicit associations between space and emotional valence. Although asymmetric motor experience may be necessary to establish body-specific associations between space and valence initially, neither motoric nor perceptual experience is needed to change these associations subsequently. The mere expectation of fluent versus disfluenct actions can drive fluency-based effects on people's implicit spatialization of “good” and “bad.” These results suggest a reconsideration of the mechanisms and boundary conditions of fluency effects.

La formación adecuada de profesionistas presenta un reto educativo a nivel mundial, este reto es de carácter multifactorial, que se ha abordado desde diferentes disciplinas. La pandemia sanitaria obligó al cierre de universidades mostrando claramente múltiples deficiencias en la implementación de sistemas tecnológicos híbridos que hicieran continua la formación universitaria. En este contexto, se desarrolla una propuesta integral que abarque las necesidades para solventar una educación híbrida. Para formular el modelo se realizó una revisión de la literatura para identificar los (...) factores críticos de éxito en la educación hibrida con recursos tecnológicos. Se caracterizó cómo funciona una institución de educación superior de forma general y se identificaron las plataformas digitales educativas y se obtuvo una primera aproximación del modelo para hacer pruebas de implementación.

Inicialmente, o texto indaga sobre o significado do exercício do filósofo social; pretende também localizar as origens do debate moderno sobre ‘subjetividade’ no pensamento filosófico e social. As idéias norteadoras de Kant, se situam na confluência e na disjunção entre razão (conhecimento) e subjetividade (moral). A partir dessa referência, o debate entre alguns pensadores considerados como pós-modernos (Badiou e Zizek), por um lado, e por outro Castoriadis que recusa esta nomenclatura, vão derivando idéias novas sobre ‘sujeito’ e ‘verdade’. Esse debate (...) não é sem conseqüências para a teoria sociológica que assume para si o desafio de introduzir a categoria de ‘sujeito’ em seus cânones (Touraine). As reflexões de Stengers servem também para questionar e aproximar as práticas da produção do conhecimento e dos discursos científicos. Finalmente, restam desafios para se pensar teorias e práticas sócio-ambientais à luz desses conceitos apresentados ao longo do texto. (shrink)

Trata-se, no presente artigo, de analisar as mudanças que historicamente tem ocorrido no EU e as rupturas na apreensâo da realidade. As atuais transformaçoes da realidade teriam levado a um asvaziamento do ser? Ou ainda, a realidade nâo teria mais nada a ver com o sujeito? Como apreender essas transformaçoes? Esta investigaçâo faz-se valer da leitura de Gramsci, por meio da qual a unidade entre se e o pensar aparece como uma possibilidade de superaçao da metafísica do sujeito à elaboraçâo (...) de uma ontología concreta.

Authoritative school climate is a relevant and novel construct that improves the academic performance and social-emotional development of students. This study aimed to evaluate the psychometric properties of reliability and validity of the Authoritative School Climate Survey (ASCS) in a sample of Chilean adolescents. A cross-sectional study was carried out, in which 808 students from 12 schools in Chile participated (55.1% men and 44.9% women), with a mean age of 15.94 (SD= 1.32). The results obtained through exploratory and confirmatory factor (...) analyzes ratified the hypothesized structure of two correlated factors. As expected, evidence of criterion validity showed significant relationships between the measures of authoritative school climate and attitude toward institutional authority. This study provides evidence regarding the psychometric quality of the scale to assess authoritative school climate, allowing its use in the Chilean context. (shrink)

La creatividad y la paz están íntimamente relacionadas, incluso en su dimensión histórica. El cambio de concepción de la paz observado por Galtung lleva a una comparación con la evolución de la noción de creatividad. Además de las mencionadas similitudes, ambos conceptos están en concomitancia en tanto en cuanto la creatividad es necesaria como herramienta para la transformación de conflictos de forma pacífica. El nexo que se propone para unir ambos conceptos es la educación, encardinada dentro de un constructo que (...) llamamos triángulo abstractivo. (shrink)

El Foro Global de Bioética en Investigación (GFBR por sus siglas en inglés) se reunió el 3 y 4 de noviembre en Buenos Aires, Argentina, con el objetivo de discutir la ética de la investigación con mujeres embarazadas. El GFBR es una plataforma mundial que congrega a actores clave con el objetivo de promover la investigación realizada de manera ética, fortalecer la ética de la investigación en salud, particularmente en países de ingresos bajos y medios, y promover colaboración entre países (...) del norte y del sur.a Los participantes en el GFBR provenientes de Latinoamérica incluyeron a eticistas, investigadores, miembros de comités de ética y representantes de autoridades sanitarias provenientes de Argentina, Brasil, Chile, Colombia, Ecuador, El Salvador, Guatemala, Honduras, Panamá, Perú, Nicaragua y la República Dominicana. Una legítima preocupación por la protección de las mujeres embarazadas y sus embriones o fetos ha llevado a la mayoría de los países de la Región de las Américas a limitar la realización de estudios con mujeres embarazadas exclusivamente a aquellos estudios específicos sobre el embarazo, y a requerir la exclusión sistemática de las mujeres embarazadas o de las mujeres que quedan embarazadas en el curso del estudio. Ciertamente, a lo largo de la historia de la ética de la investigación, se ha creído erróneamente que proteger a una población es sinónimo de excluirla de los estudios. Se sabe ahora que proceder así implica exponer a riesgos mucho mayores a la población que se busca proteger. El embarazo implica cambios fisiológicos sustantivos e impacta profundamente la manera como el cuerpo metaboliza los medicamentos. Sin embargo, por evitar hacer investigación con mujeres embarazadas, no se ha producido la evidencia científica necesaria para tomar decisiones sobre tratamientos e intervenciones preventivas con dosis eficaces y seguras para ellas y sus embriones o fetos. A manera de ilustración, en el 2001 había en los Estados Unidos apenas más de una docena de medicamentos aprobados para uso en el embarazo (1) y en el 2011 la Food and Drug Administration (FDA) aprobó por primera vez en 15 años un medicamento para su uso en el embarazo (2). Como consecuencia de no haber producido la evidencia necesaria, se pone en riesgo la salud de las mujeres embarazadas cada vez que se les da atención médica. Las mujeres embarazadas se enferman y las mujeres enfermas se embarazan, y no se sabe si los medicamentos que se les da son eficaces o siquiera seguros para ellas y sus embriones o fetos. (shrink)

Simão José da Luz Soriano (1802-1891) é principalmente conhecido pelos livros que escreveu sobre a guerra civil de 1828-1834 e a implantação do liberalismo em Portugal. As reflexões po­líticas realizadas em 1858 e em 1860 revelam-nos uma outra faceta da sua obra: a crítica apai­xonada dos erros do regime constitucional. Contudo, as suas observações só podem ser enten­didas se forem relacionadas com o liberalismo moderado da segunda metade do século XIX. O presente artigo pretende fazer a análise da relação entre (...) o estudo da realidade política e o pen­samento do autor. (shrink)

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Resumen de la tesis doctoral La consistencia del yo en el pensamiento de Ortega y Gasset, presentada en la Universidad Autónoma de Madrid, el 28 de noviembre de 1991, por José La.saga Medina, bajo la dirección de D. Julio Bayón Cerdán.

The notion of intersemiosis suggests the game relationships between the multiple interacting signifying spheres of culture, but the term can also be fitly applied to the study of certain extraordinary artistic texts. This study makes use of one such book, Julio Cortazar's Around the Day in Eighty Worlds, to show how the sui generis interplay of the book's semantic spheres simultaneously models and renews the complex cultural processes of the production of meaning. This often reprinted and hard-tocategorize book that for (...) years has remained at the outskirts of Latin American culture is also an ideal example to explore the dynamics between the center and periphery of culture as well as the writer's role in the creative renewal of cultural repertoires. By drawing a bridge over the apparent gap between the semiotics of culture and the semiotics of the artistic text, the present study attempts to approximate the critical-creative spirit of the late great theoretician Yurij Lutman.
