La atención es uno de los fenómenos psicológicos más presentes en la obra orteguiana y, a la vez, uno de los más desatendidos por la crítica. Habitualmente el fenómeno ha quedado eclipsado por ideas tradicionalmente más nodales como la de “perspectiva”, sin embargo, no podemos ignorar que ideas como esta hallan su fundamento precisamente sobre el fenómeno de la atención, lo que le otorga una importancia a considerar. En el presente libro, mediante una revisión crítica de los textos orteguianos, se (...) despliega y reúne un conjunto de argumentos con los que defender la centralidad de la atención en el pensamiento orteguiano ofreciendo, con ella, uno de los elementos cardinales en la estructuración sistemática de su obra, pues, como veremos, es en la atención donde el autor halla el fundamento para edi car su método perspectivista y, a su vez, donde descansa cierta posibilidad de cristalizar su doctrina raciovitalista.

El mito platónico de Prometeo, con el robo del fuego a los dioses, simboliza el despegue del más apasionante reto de la Humanidad, la aventura del conocimiento. Dédalo con sus ingenios persiguió en vano la estela; y el rapto de Europa por Zeus, no en su vertiente ortodoxa, sino tal como lo representa Bayros, clausura un periplo en pos del bienestar que hoy se muestra tan esperanzador como amenazante. Cuando estamos a punto de realizar el imperativo de Francis Bacon dominando (...) el mundo natural, éste se resiste y rebela dejando al descubierto la fragilidad de la criatura humana. Piqueras como contrapunto esporádico es un testigo del pasado, un aldabonazo en la conciencia. El imperativo tecnológico resume este momento de inflexión en el que nos hallamos: un punto ¿de no retorno?, ante el que la conciencia moral zozobra y que puede marcar el sino de la humanidad doliente. Hasta aquí nos ha traído el apogeo de lo racional, hasta la crisis que todo lo impregna. Si esto es un cuento de Calleja, no acertamos a vislumbrar la moraleja. (shrink)

A partir de la aparentemente contradictoria expresión “nostalgia de futuro”, en el presente artículo nos adentramos en el análisis del complejo entramado de tensiones temporales que subyacen a la experiencia humana, en concreto bajo la coloración del tono nostálgico. Trataremos de analizar las relaciones de interdependencia que guardan los distintos horizontes temporales, tanto en la experiencia nostálgica como en la experiencia originaria a la que esta refiere y que es materia de evocación. En tal contexto, pondremos especial énfasis en el (...) papel de las expectativas, y en su influencia en la “futura” emergencia del temple nostálgico, un papel que, aun cuando actúan de manera preconsciente, resulta esencial para comprender la sensación de pérdida de familiaridad que siente quien ve incumplidas tales pretensiones.

Nostalgia refers to that painful experience due to the impossibility of recovering a past whose memory provokes a feeling of comforting happiness and which, nevertheless, inevitably attracts us. This leads us to a reiterated tendency to remember in search of that space of familiarity, of sense, which we know is lost, although we trust that it’s still redeemable. In this article we will analyze this possibility of reencounter that, in its expression, enables a potential recognition of oneself, that is, an (...) opportunity to reaffirm the past-present continuity that reinforces the unfolding of a life project today, looking at the future.

Attention is an essential phenome-non to understand the scope of the perspectival methodology in Ortega; therefore, it’s a useful tool to go further in the study of the applicability of ratiovitalism. At the same time, for it is easy tracking in the Ortega’s work, it’s a good knoll to investigate the sources which influenced Ortega in the establishment and, therefore, to explore the shaping of his meth-odology. Our study, based on an analysis of the phenomenon of attention in Ortega's work, (...) guides us to find, in the phenomenolog-ical studies of perception, the core of such influence, thereby accentuating the role of phenomenology in the establishment of Ortega's thought.

Many times we have discussed about the appropriateness of situating to Vygotski in the Olympus of psychology. Even today, 80 years later, his theories continue creating as many supporters, defenders of his originality, as effusive critics who accuse the methodological shortcomings of his work. In our view, one of the shortcomings that have accused more his work is the lack of a solid theoretical foundation that endows meaning with the available host of data and results. Therefore, the objective of this (...) article is to show a feasible solution that would be to approach, sometimes encounter with certain phenomenological propositions, for that matter, from the phenomenological studies of perception and its attention to the weight of cultural predicates, where the language is the main element and, at the same time, the meeting point with Vygotski which will help strengthen the foundations of its proposal.

La “percepción” es uno de los elementos imprescindibles para la comprensión del pensamiento orteguiano: es la vía por la que nuestra consciencia se abre a lo circundante, fundamento de toda perspectiva y, en consecuencia, elemento fundamental para el autor. A su vez, es uno de los elementos que convierte al pensador madrileño en uno de los estudiosos más originales en este campo. El presente artículo pretende mostrar cómo, para Ortega, ya desde sus inicios, su filosofía de la percepción –de matriz (...) perspectivista–, al fundamentarse en la mundaneidad del individuo y apoyar su percepción cognoscitiva sobre el fenómeno de la atención, incluye o muda, de un modo nada forzado, a una filosofía de la cultura, pues cuando Ortega habla de percepción, lo hace siempre en tanto percepción con predicados culturales. Fue Ortega uno de los primeros en advertir lo ineludible de dicha cualidad. (shrink)

For over a decade neuroscience has uncovered that appropriate decision-making in daily life decisions results from a strong interplay between cognition and covert biases produced by emotional processes. This interplay is particularly important in social contexts: lesions in the pathways supporting these processes provoke serious impairments on social behavior. One important mechanism in social contexts is empathy, fundamental for appropriate social behavior. This paper presents arguments supporting this connection between cognition and emotion, in individual as well as in social contexts. (...) The central claim of this paper is that biologically inspired cognitive architectures ought to include these mechanisms. A taxonomy of computational models addressing emotions is presented, together with a brief survey of the research published in this area. The Prisoner Dilemma game is used as a case study exposing the trade-off between individual rationality and cooperative behavior. Experiments using a simple implementation of empathy and emotion expression, employing an Iterated Prisoner Dilemma setup, illustrate the emergence of a cooperative behavior mutually beneficial for both players.

This paper compares pair and Mob programming in university courses from students' perceptions of technical and human aspects. Wilcoxon signed rank tests were performed. Results indicated that students preferred pair programming in technical aspects and in a global evaluation they completed.

In 1966, a team made up of Brazilian and foreign scientists spent a week carefully recording the body temperature and other clinical signs and symptoms of 110 Tiriyó Indigenous people in their communities along the Brazil-Suriname border. Led by the Yale University virologist and immunologist Francis Black, the researchers faced an "epidemic" with a special profile, distinct from those most common in Indigenous populations, which usually resulted in widespread illness, the collapse of subsistence activities, hunger, and as a rule, elevated (...) mortality.Rather, what was happening with the Tiriyó was a planned event, controlled and carefully...

In this paper we prove the equivalence between the Gentzen system G LJ*\c , obtained by deleting the contraction rule from the sequent calculus LJ* (which is a redundant version of LJ), the deductive system IPC*\c and the equational system associated with the variety RL of residuated lattices. This means that the variety RL is the equivalent algebraic semantics for both systems G LJ*\c in the sense of [18] and [4], respectively. The equivalence between G LJ*\c and IPC*\c is a (...) strengthening of a result obtained by H. Ono and Y. Komori [14, Corollary 2.8.1] and the equivalence between G LJ*\c and the equational system associated with the variety RL of residuated lattices is a strengthening of a result obtained by P.M. Idziak [13, Theorem 1].An axiomatization of the restriction of IPC*\c to the formulas whose main connective is the implication connective is obtained by using an interpretation of G LJ*\c in IPC*\c.

The Entrepreneurial University plays a central role in entrepreneurial ecosystems and actively influences the development of entrepreneurial human capital, which is a critical asset for many economies. There is thus a requirement for the identification and strengthening of entrepreneurial competences, but no previous studies have included any analysis of these competences in the university context using an approach based on profiles. The present study fills this gap by investigating the existence of different entrepreneurial profiles among students, based on their competences. (...) It also defines key competences that are critical for differentiating between these profiles and improving entrepreneurial competence levels more generally. To meet these objectives, a field research campaign was developed. Data on 1104 students from various degrees and faculties were collected and analyzed using a quantitative methodological approach. The results reveal the existence of four entrepreneurial competence profiles, namelylow profile,top profile,social profile, andgrit profile. Among as many as 12 possible entrepreneurial competences, the most prominent can explain to a large extent the entrepreneurial profiles of students; these are networking and professional social skills, community engagement, perseverance of effort, and consistency of interest. The results provide evidence of the importance of social capital andgrit. In addition to their contribution to the theory in this area and the development of the Entrepreneurial University paradigm, the results are also useful for the design of training strategies aimed at strengthening the levels of competence of students, thereby providing universities with tools to foster the creation of entrepreneurial human capital.

The aim of the present research was to test whether involvement in a 14-days training program in the performing arts could reduce implicit biases. We asked healthy participants to complete an Implicit Association Test to assess biased attitudes to physical illness in two separate sessions, before and after the training program. Two separate control groups matched by age, gender and educational level completed the two IAT sessions, separated by same number of days, without being involved in the training program. Results (...) showed that participants who were involved in the training program reduced their implicit bias toward illness measured through IAT in the second session. This reduction in IAT measures was not observed in the control samples, despite the two IAT measures being matched in temporal delay with the experimental group. These findings suggest that an interventional program based on the performing arts could be effective in reducing levels of implicit biases among the general population. (shrink)

In this paper we obtain a finite Hilbert-style axiomatization of the implicationless fragment of the intuitionistic propositional calculus. As a consequence we obtain finite axiomatizations of all structural closure operators on the algebra of {–}-formulas containing this fragment.

Previous studies have demonstrated that double phosphorylation of a protein can lead to bistability if some conditions are fulfilled. It was also shown that the signaling behavior of a covalent modification cycle can be quantitatively and, more importantly, qualitatively modified when this cycle is coupled to a signaling pathway as opposed to being isolated. This property was named retroactivity. These two results are studied together in this paper showing the existence of interesting phenomena—oscillations and bistability—in signaling cascades possessing at least (...) one stage with a double-phosphorylation cycle as in MAPK cascades.

We determined the prevalence of eating disorder symptoms among elite Spanish athletes from a broad range of sports and levels of competition and examined the associations between the presence of symptoms and perceived sport-specific weight pressures. We surveyed 646 elite athletes representing 33 sports from top-division teams and two elite athlete training centers in Catalonia. Based on the results of the Eating Attitudes Test-26 responses, 5.1% of athletes were at risk of EDs. The highest rates of ED symptoms were observed (...) in male endurance athletes and female esthetic athletes. Competition level was not a risk factor. The only gender differences in the presence of ED symptoms by competing level were observed in athletes competing at the national level. Female athletes with ED symptoms scored higher on the two subscales of the Spanish version of the Weight Pressures in Sport tool: coach and sport-specific pressures and pressures from teammates and due to uniform. Male athletes with ED symptoms scored higher on the pressures due to uniform subscale. Finally, symptomatic female but not male athletes competing at international and national levels also perceived greater sport-specific weight pressures. (shrink)

In this paper we study the relations between the fragment L of classical logic having just conjunction and disjunction and the variety D of distributive lattices, within the context of Algebraic Logic. We prove that these relations cannot be fully expressed either with the tools of Blok and Pigozzi's theory of algebraizable logics or with the use of reduced matrices for L. However, these relations can be naturally formulated when we introduce a new notion of model of a sequent calculus. (...) When applied to a certain natural calculus for L, the resulting models are equivalent to a class of abstract logics (in the sense of Brown and Suszko) which we call distributive. Among other results, we prove that D is exactly the class of the algebraic reducts of the reduced models of L, that there is an embedding of the theories of L into the theories of the equational consequence (in the sense of Blok and Pigozzi) relative to D, and that for any algebra A of type (2,2) there is an isomorphism between the D-congruences of A and the models of L over A. In the second part of this paper (which will be published separately) we will also apply some results to give proofs with a logical flavour for several new or well-known lattice-theoretical properties.

en las últimas décadas la bioética se ha vuelto un tema crucial para la Iglesia. La dinámica propia de la técnica, que se auto-propulsa y avanza con independencia de criterios éticos, amenaza de modo inminente la dignidad humana. En la actualidad ya existe la posibilidad de producir artificialmente seres humanos, incluso sin la mediación de gametos. Pero lo que no existe son los índices para reconocer cuándo una célula intervenida sigue siendo sólo una célula -eventualmente pluripotencial y por tanto con (...) grandes promesas terapéuticas; o cuando ya es una célula totipotencial, un cigoto, un organismo humano: una persona. Ciencia, filosofía y teología, como se mostrará en este artículo, se unen en la reflexión bioética para encontrar de modo urgente esas señales; puesto que la biotecnología sigue avanzando, y hay de tomar posición sobre sus descubrimientos. La Iglesia no puede callar frente a una posible producción artificial, instrumentalización y destrucción de personas; que aunque estén en su fase unicelular y hayan llegado al mundo como artefactos, siguen siempre siendo el reflejo del Rostro de Dios.

In this essay, some theoretical semiotic issues concerning immersive technologies are presented and discussed. In particular, the somatic and corporeal dimensions of the construction of the user-visual hybrid, the problematic of point of view and realism, and the narrativity inscribed in immersive technologies will be discussed. The objective is twofold: tracing the semiotic perspective on the real/virtual relationship and questioning certain rhetoric of immersivity that underlies precise ideologies circulating in the contemporary imagery.

The object of this paper is to make a study of four systems of modal logic (S4, S5, and their intuitionistic analogues IM4 and IM5) with the techniques of the theory of abstract logics set up by Suszko, Bloom, Brown, Verdú and others. The abstract concepts corresponding to such systems are defined as generalizations of the logics naturally associated to their algebraic models (topological Boolean or Heyting algebras, general or semisimple). By considering new suitably defined connectives and by distinguishing between (...) having the rule of necessitation only for theorems or as a full inference rule (which amounts to dealing with all filters or with open filters of the algebras) we are able to reduce the study of a modal (abstract) logic L to that of two nonmodal logics L - and L + associated with L. We find that L is "of IM4 type" if and only if L - and L + are both intuitionistic and have the same theorems, and logics of type S4, IM5 or S5 are obtained from those of type IM4 simply by making classical L -, L + or both. We compare this situation with that found in recent approaches to intuitionistic modal logic using birelational models or using higher-level sequent-systems. The treatment of modal systems with abstract logics is rather new, and in our way to it we find several general constructions and results which can also be applied to other modal systems weaker than those we study in detail.
