Let T be a second-order arithmetical theory, Λ a well-order, λ < Λ and X ⊆ ℕ. We use $[\lambda |X]_T^{\rm{\Lambda }}\varphi$ as a formalization of “φ is provable from T and an oracle for the set X, using ω-rules of nesting depth at most λ”.For a set of formulas Γ, define predicative oracle reflection for T over Γ ) to be the schema that asserts that, if X ⊆ ℕ, Λ is a well-order and φ ∈ Γ, then$$\forall \,\lambda (...) < {\rm{\Lambda }}\,.$$In particular, define predicative oracle consistency ) as Pred–O–RFN{0=1}.Our main result is as follows. Let ATR0 be the second-order theory of Arithmetical Transfinite Recursion, ${\rm{RCA}}_0^{\rm{*}}$ be Weakened Recursive Comprehension and ACA be Arithmetical Comprehension with Full Induction. Then,$${\rm{ATR}}_0 \equiv {\rm{RCA}}_0^{\rm{*}} + {\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - RFN}}\,_{{\bf{\Pi }}_2^1 } \left.$$We may even replace ${\rm{RCA}}_0^{\rm{*}}$ by the weaker ECA0, the second-order analogue of Elementary Arithmetic.Thus we characterize ATR0, a theory often considered to embody Predicative Reductionism, in terms of strong reflection and consistency principles.

In a society where mobility, globalization and contact with people from other cultures have become its basic descriptors, the enhancement of plurilingualism and intercultural understanding seem to be of the utmost concern. From a Positive Psychology Perspective, agency is the human capacity to affect other people positively or negatively through their actions. This agentic vision can be related to mediation, a concept rooted in the socio-cultural learning theory where social interaction is considered a fundamental cornerstone in the development of cognition. (...) Social interactions in the language learning setting may be facilitated through musical activities due to its social bonding effect. This paper tries to offer insights on how a musical-mediated experience in language learning may develop students’ interpersonal and collaborative competences to become active members of a more inclusive society. Mediation, considered as a paradigm shift in the foreign language classroom and the different out-of-class language learning possibilities, could also provide an environment where learners maximize their emotional intelligence. Our paper focuses on this paradigm shift spearheaded by the CEFR Companion Volume and the considerable repercussions it is bound to have for foreign language didactics, as cooperative tasks become central to foreign language learning. We hypothesize that mediated language learning experiences imply a socioemotional change in learners, focusing on the others, on their needs and interests, by trying to help them understand texts, concepts or facilitating communication with their peers. An intervention with a musical-mediated language learning experience was designed and implemented in the classroom. A self assessment scale with mediation descriptors and the socioemotional expertise scale (SEE) were administered. Results show that students become more mindful of their strengths, of their capacity for collaborating and team working. This leads to more awareness of their mediation skills. Students’ mediation skills correlate significantly with their socio-emotional skills, more concretely with their expressivity. The implementation of a musical-mediated experience also promoted tolerance and enhanced learners’ intrinsic motivation for language learning at the same time as they acknowledged their diversity.

By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a consequence, we obtain (...) results on the quantifier complexity, finite axiomatizability and relative strength of schemes for Δn+1-formulas. (shrink)

A well known theorem proved by J. Paris and H. Friedman states that BΣn +1 is a Πn +2-conservative extension of IΣn . In this paper, as a continuation of our previous work on collection schemes for Δn +1-formulas , we study a general version of this theorem and characterize theories T such that T + BΣn +1 is a Πn +2-conservative extension of T . We prove that this conservativeness property is equivalent to a model-theoretic property relating Πn-envelopes and (...) Πn-indicators for T . The analysis of Σn +1-collection we develop here is also applied to Σn +1-induction using Parsons' conservativeness theorem instead of Friedman-Paris' theorem.As a corollary, our work provides new model-theoretic proofs of two theorems of R. Kaye, J. Paris and C. Dimitracopoulos : BΣn +1 and IΣn +1 are Σn +3-conservative extensions of their parameter free versions, BΣ–n +1 and IΣ–n +1. (shrink)

Resumen: En la historia de la recepción de Samuel Beckett en los países de habla no inglesa, la primera traducción de Comment c’est al castellano, realizada por José Emilio Pacheco en 1966, aparece como un hito aislado y deslumbrante. Esta traducción a partir del texto original en francés, hecha por el poeta mexicano cuando tenía 27 años, no tuvo una repercusión notable en su momento, a pesar de la audacia de la empresa y de la brillantez de la traducción. Sin (...) embargo, a raíz de la trayectoria de Pacheco como crítico, traductor y poeta de primera magnitud, se considera necesario hacer una evaluación en profundidad de este texto único. El objetivo de este artículo es el de analizar la versión de Pacheco del texto beckettiano por medio de un acercamiento al contexto histórico y a los elementos propios de su bagaje cultural que el poeta aporta a la elaboración de su traducción. Se trata, en definitiva, de explicar cómo se lee a Beckett en español por medio de Pacheco.: The first translation into Spanish of Samuel Beckett’s Comment c’est, by José Emilio Pacheco, Cómo es, stands out as a dazzling and unprecedented landmark in the history of the reception of the Irish author in non-English-speaking countries. In his translation the 27-year-old Mexican poet took the French original version as his main source but, despite its daring quality and the brilliance of the text rendered into Spanish, it had little impact in the cultural atmosphere of its day. In light of Pacheco’s standing in the world of letters as a first-rank critic, translator and poet, it is deemed necessary a reassessment of this unique text. The aim of this article is to analyze Pacheco’s translation of Samuel Beckett’s novel; for this purpose, the historical context and the personal elements that the poet incorporated from his personal background into his version of Comment c’est will be studied in detail. All in all, the final objective of this research is to explain how Beckett is read in Spanish through Pacheco’s version. (shrink)

Background:The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students.Objectives:To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain.Research design:A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat room platform. A thematic, inductive (...) analysis was performed of the information gathered.Participants and research context:Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic.Ethical considerations:The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos.Results:Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions.Conclusions:These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)

The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness. Therefore, it is necessary to measure and monitoring the levels of PA in childhood and adolescence, since it may be useful to describe their current health status and the association with physical fitness, as well as to reveal putative consequences in the future. Within the educational field, it has been shown (...) that physical education (PE) classes are a favorable context for the creation of healthy physical-sports habits and self-determined motivation could be a key for explaining the level of PA practice. For this reason, the purpose of this research was to study the mediating role of integrated regulation (IR) on the relationship between PA and physical fitness in children and adolescents. A total of 325 students between 11 and 14 years old participated in the study. The level of PA was estimated through the specific Physical Activity Questionnaire for Children (PAQ-C), while motivation and IR were measured by using the Perceived Locus of Causality scale (PLOC-2). In addition, physical fitness was measured through the Eurofit fitness battery of tests, composed of three body composition measures and seven tests of different physical capacities. The physical fitness score showed no differences when genders were compared. After regression analysis, the resulti... (shrink)

A first impression matters, in particular when encounters are brief as in most doctor-patient interactions. In this study, we investigate how physicians’ body postures impact patients’ first impressions of them and extend previous research by exploring posture effects on the perception of all roles of a physician – not just single aspects such as scholarly expertise or empathy. In an online survey, 167 participants ranked photographs of 4 physicians in 4 postures. The results show that male physicians were rated more (...) positively when assuming open rather than closed postures with respect to all professional physician roles. Female physicians in open postures were rated similarly positive for items related to medical competence, but they tended to be rated less favorably with respect to social skills. These findings extend what is known about the effects of physicians’ body postures on the first impressions patients form to judge physicians’ medical versus social competencies. We discuss practical implications and the need for more research on interaction effects of body postures and physician gender on first impressions. (shrink)

One of the objectives in the field of artificial intelligence for some decades has been the development of artificial agents capable of coexisting in harmony with people and other systems. The computing research community has made efforts to design artificial agents capable of doing tasks the way people do, tasks requiring cognitive mechanisms such as planning, decision-making, and learning. The application domains of such software agents are evident nowadays. Humans are experiencing the inclusion of artificial agents in their environment as (...) unmanned vehicles, intelligent houses, and humanoid robots capable of caring for people. In this context, research in the field of machine ethics has become more than a hot topic. Machine ethics focuses on developing ethical mechanisms for artificial agents to be capable of engaging in moral behavior. However, there are still crucial challenges in the development of truly Artificial Moral Agents. This paper aims to show the current status of Artificial Moral Agents by analyzing models proposed over the past two decades. As a result of this review, a taxonomy to classify Artificial Moral Agents according to the strategies and criteria used to deal with ethical problems is proposed. The presented review aims to illustrate (1) the complexity of designing and developing ethical mechanisms for this type of agent, and (2) that there is a long way to go (from a technological perspective) before this type of artificial agent can replace human judgment in difficult, surprising or ambiguous moral situations.

Delivery riders became frontline workers who assisted everyone in getting their daily supplies. They transported them to their destinations when the pandemic started, and everyone had to stay home to stop the COVID-19 virus from spreading. Thus, this study explores the experiences, challenges, and coping mechanisms of 15 Female Delivery Riders in Bulacan, Philippines. The study employed Heideggerian Phenomenology and Interpretative Phenomenological Analysis (IPA). Further, the following themes arise: (1) The Realist, (2) The Accommodated, (3) The Vulnerable, and (4) The (...) Determined. These themes highlighted the experiences and challenges faced by the participants. Moreover, it is highly suggested that female employees should be given preferential assistance given their physical capabilities and role in the family. Thus, local government units should provide an alternative source of income that will allow them to have quality time with their family, especially their children. (shrink)

In spoken interactions, interlocutors carefully plan and time their utterances, minimising gaps and overlaps between consecutive turns. Cross-linguistic comparison has indicated that spoken languages vary only minimally in terms of turn-timing, and language acquisition research has shown pre-linguistic vocal turn-taking in the first half year of life. These observations suggest that the turn-taking system may provide a fundamental basis for our linguistic capacities. The question remains however to what extent our capacity for rapid turn-taking is determined by modality constraints. The (...) avoidance of overlapping turns could be motivated by the difficulty of hearing and speaking at the same time. If so, turn-taking in sign might show greater toleration for overlap. Alternatively, signed conversations may show a similar distribution of turn-timing as spoken languages, thus avoiding both gaps and overlaps. To address this question we look at turn-timing in question-answer sequences in spontaneous conversations of Sign Language of the Netherlands. The findings indicate that although there is considerable overlap in two or more signers' articulators in conversation, when proper allowance is made for onset preparation, post-utterance retraction and the intentional holding of signs for response, turn-taking latencies in sign look remarkably like those reported for spoken language. This is consistent with the possibility that, at least with regard to responses to questions, speakers and signers follow similar time courses in planning and producing their utterances in on-going conversation. This suggests that turn-taking systems may well be a shared cognitive infrastructure underlying all modern human languages, both spoken and signed. (shrink)

We examined the question of how “salient others” influence economic decisions. We proposed that moral motives actively shape economic decisions in social situations. In an experiment, we varied the decision situation and the moral motive. As hypothesized, moral motives influenced decision behavior only in social situations but not in non-social situations. In addition, we showed that in anonymous social one-shot situations, individuals are susceptible to situational moral motive framing. In contrast, situational cues were ineffective if a moral motive was already (...) established in the relationship between interacting partners. The results showed that moral motives matter in economic decision-making and that people infer information about morally “appropriate” behavior in anonymous social interactions from moral cues provided by the situation. The presented research offers a psychological explanation for why individuals make different decisions in economic decision situations depending on the social situation. (shrink)

Se problematiza la conexión entre la libertad práctica y trascendental en la Crítica de la razón pura. La intención es explicitar las dificultades que enfrenta Kant al relacionar estos sentidos de libertad dentro del marco de la filosofía crítica. Por lo general, los intérpretes entienden la relación entre estos dos sentidos de libertad como ontológica o como conceptual. Se quiere mostrar que ninguna de estas interpretaciones alcanza a superar los presuntos dogmatismos racionalista y empirista que, en conformidad con Kant, sustentan (...) las posturas del proponente de la Tesis y de la Antítesis, respectivamente. The article discusses the connection between practical and transcendental freedom in the Critique of Pure Reason, in order to reveal the difficulties faced by Kant when he relates these two meanings of freedom in the context of critical philosophy. Interpreters have generally understood the relation between these two meanings of freedom as ontological or conceptual. The objective of this article, however, is to show that neither of those interpretations manages to overcome the rationalist and empiricist dogmatism that, according to Kant, support the positions of the proponents of the Thesis and the Antithesis, respectively.

Este trabajo pretende analizar críticamente la interpretación llevada a cabo por Étienne Balibar en relación con las tres antinomias de la igualibertad descritas en su obra, así como con las definiciones balibarianas de «ciudadanía social», «Constitución material» y «co-ciudadanía». Para ello, se hará un recorrido por el pensamiento del filósofo a través de su obra La igualibertad. A continuación, se confrontarán algunas de sus tesis con el propósito de mostrar sus límites internos a través de la filosofía del derecho mediante (...) la obra de Luigi Ferrajoli. Para terminar, se propone la propuesta de constitucionalismo garantista de Ferrajoli como posible superación de las antinomias planteadas por Balibar acerca de la igualibertad. (shrink)

This book discusses how scientific and other types of cognition make use of models, abduction, and explanatory reasoning in order to produce important and innovative changes in theories and concepts. Gathering revised contributions presented at the international conference on Model-Based Reasoning, held on October 24–26 2018 in Seville, Spain, the book is divided into three main parts. The first focuses on models, reasoning, and representation. It highlights key theoretical concepts from an applied perspective, and addresses issues concerning information visualization, experimental (...) methods, and design. The second part goes a step further, examining abduction, problem solving, and reasoning. The respective papers assess different types of reasoning, and discuss various concepts of inference and creativity and their relationship with experimental data. In turn, the third part reports on a number of epistemological and technological issues. By analyzing possible contradictions in modern research and describing representative case studies, this part is intended to foster new discussions and stimulate new ideas. All in all, the book provides researchers and graduate students in the fields of applied philosophy, epistemology, cognitive science, and artificial intelligence alike with an authoritative snapshot of the latest theories and applications of model-based reasoning.

The purpose of our article is to contemplate, from an aesthetic-artistic vision, the principles of the Universal Declaration on Bioethics and Human Rights, adopted by UNESCO in 2005. As a result of a restful, attentive and calm look (contemplation), we believe that the development of a line of thought capable of proposing answers to the great questions posed by the current existential and historical paradigm shift requires an effort of transdisciplinary dialogue. On the one hand, reason, as a specific and (...) differential faculty of the human being, must overcome the limits of its reduction to mere empirical scientism and redefine itself as a reason with an open horizon. On the other hand, the creation of works of art and the aesthetic experience constitutes a way of understanding the complexity and multiplicity of reality. Based on two classic works of art: "The kidnapping of the Sabinas" (Da Cortona) and "Liberty leading the people" (Delacroix) we propose a bio-aesthetic experience on the two fundamental axes on which the principles of the Declaration of UNESCO navigate, which are the centrality of the person and of society. Knowing and deepening such principles, through bio-aesthetic contemplation, is shown as a valid educational instrument, which entails the art of stimulating the capacity to reverberate the beauty existing in the world when good is manifested in human behavior and recognizing the transforming power of art, which facilitates a pedagogical and comprehensive assimilation of the principles of the UNESCO Declaration.

In this work, we shall study structural abduction and how ways of searching for solutions to the corresponding abductive problems could be modeled. Specifically, we shall define modal semantic tableaux for normal modal systems and study its applications to structural abduction. This method even makes structural abduction clearer and, as it shall be seen, when a radical change of logic is epistemologically required, the corresponding tableau will have pertinent information to suggest it.
