People implicitly associate positive ideas with their dominant side of space and negative ideas with their non-dominant side. Right-handers tend to associate “good” with “right” and “bad” with “left,” but left-handers associate “bad” with “right” and “good” with “left.” Whereas right-handers' implicit associations align with idioms in language and culture that link “good” with “right,” left-handers' implicit associations go against them. Can cultural conventions modulate the body-specific association between valence and left-right space? Here, we compared people from Spanish and Moroccan (...) cultures, which differ in the strength of taboos against the use of the left hand, and therefore in their preference for the right. Results showed stronger explicit associations between space and valence in Moroccan participants than in Spaniards, but they did not show any increased tendency for right-handed Moroccans to associate “good” with “right” implicitly. Despite differences in cultural conventions between Spaniards and Moroccans, we find no evidence for a cross-cultural difference in the implicit association between space and valence, which appears to depend on patterns of bodily experience.

La diversidad cultural en la sociedad y en las aulas es una realidad patente que hay que tener en cuenta y no obviar. La investigación en el campo de las actitudes desarrolladas por parte de los agentes educativos se hace inexorablemente pertinente y necesaria para la construcción de una sociedad futura libre de conflictos innecesarios. En este estudio se han analizado las actitudes familiares mediante entrevista semiestructurada. Se realizó un análisis cualitativo y cuantitativo, obteniendo el perfil sobre pensamiento en torno (...) a la diversidad cultural de progenitores e hijos. El grado de concordancia de dichas actitudes queda reflejado en el análisis de los resultados, apreciando desconocimiento de grupos culturalmente diversos, ventajas de enriquecimiento personal, convicción sobre la necesidad de integrar tanto a los estudiantes como a sus familias, preparación del profesorado y fomento de unas relaciones óptimas entre alumnos, docentes y familias. No obstante, existen divergencias en la función de la escuela con relación a las conductas, creencias, tradiciones y dificultades, y a la formación de los docentes para superarlas y para el tratamiento de la diversidad.

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)

Durante el estudio se encontraron aspectos teóricos que permiten entender la evolución del concepto, acceder a modelos, evaluar la repercusión del fenónemo y constatar instrumentos para su evaluación, así como obtener sugerencias para controlarlo. Se concluye que el estrés puede ser percibido como positivo (...) o negativo según el manejo que hace cada individuo y su estilo de afrontarlo, es una manifestación relacionada con el proceso salud enfermedad en el que, para algunos, contribuye al crecimiento personal y en otros, a su malestar o enfermedad. ABSTRACT With a qualitative approach and descriptive scope, the present article takes as an objective to synthesize aspects of materials published in diverse sources related to the stress for which uses the method of bibliographical review. During the study there were theoretical aspects that allow understanding the evolution of the concept, gaining access to models, evaluating the aftereffect of the phenomenon and state instruments for their evaluation, as well as obtaining suggestions to control it. It was concluded that the stress can be perceived as positive or negative according to the handling that there does every individual and its style of confronting it, a declaration related to the process is a health illness in the one that, for some, contributes to the personal growth and in others, to its discomfort or illness.

La Alhambra, antiguo monumento islámico levantado entre los siglos xiii y xv en la ciudad andaluza de Granada para albergar a la corte real nazarí, ha sido privilegiado objeto de reflexión desde finales del siglo xviii para los orientalistas. Este artículo propone una lectura poscolonial y posmoderna consecuente de la Alhambra con el fin de superar precisamente el horizonte orientalista fijado de manera estereotípica sobre todo por los viajeros románticos. Para ello introduce al lector en qué significa el discurso poscolonial, (...) y cómo la obra del arabista británico Robert Irwin, responde a esa lógica posmoderna. Se finaliza criticando la posición de éste por inconsecuentemente poscolonial al sostenerse en una jerarquía lingüística, donde la lengua inglesa tiene un lugar privilegiado, al haberse abandonado las fuentes del conocimiento locales simplemente por no expresarse en los circuitos académicos anglosajones. L’Alhambra, ancien monument islamique édifié du xiiie au xve siècle dans la ville andalouse de Grenade pour héberger la cour royale nasride, a été un objet privilégié de réflexion pour les orientalistes dès la fin du xviiie siècle. Cet article propose une lecture postcoloniale et postmoderne radicale de l’Alhambra afin de dépasser précisément l’horizon orientaliste fixé de manière stéréotypée, en particulier par les voyageurs romantiques. Pour ce faire, il introduit le lecteur dans le processus de signification du discours postcolonial, et montre comment l’œuvre de l’arabisant britannique Robert Irwin répond à cette logique postmoderne. Il critique en conclusion la position de celui-ci, montrant l’inconséquence de ses positions postcoloniales qui négligent les sources locales de connaissance, simplement parce qu’elles ne s’expriment pas à l’intérieur des cercles académiques anglo-saxons.

It is necessary to reconsider P. M. S. Hacker’s assessment of Kant and Wittgenstein’s philosophical affinities and the question concerning Wittgenstein’s alleged use of “transcendental arguments”. First, Alfred Norman’s reading of the Tractatus Logico-Philosophicus as a thought experiment receives revision to develop a view of the Critique of Pure Reason as a large-scale thought experiment that shares important logical features with the Tractatus. Then the question is addressed whether the middle Wittgenstein and the pre-critical Kant employed any thought experiments that (...) could be equally characterised as “transcendental arguments”. A rational reconstruction of both thinkers’ arguments is carried out in the light of the contemporary literature on thought experimenting. The novelty and relevance of this approach is the emphasis laid upon a largely neglected affinity between Kant and Wittgenstein, namely the systematic use of thought experiments in their epistemological pursuits. The conclusions are: i) Wittgenstein’s and Kant’s magna opera can be seen as philosophical thought experiments that attempt to try out the limits of language and the limits of possible experience respectively; ii) Both philosophers developed arguments that can be designated as transcendental if only from a methodological standpoint; and iii) some key arguments put forward by the middle Wittgenstein in the determination of the structure of visual space could be characterised better as thought experiments than transcendental arguments.

Philosophy of logic is a fundamental part of philosophical study, and one which is increasingly recognized as being immensely important in relation to many issues in metaphysics, metametaphysics, epistemology, philosophy of mathematics, and philosophy of language. This textbook provides a comprehensive and accessible introduction to topics including the objectivity of logical inference rules and its relevance in discussions of epistemological relativism, the revived interest in logical pluralism, the question of logic's metaphysical neutrality, and the demarcation between logic and mathematics. Chapters (...) in the book cover the state of the art in contemporary philosophy of logic, and allow students to understand the philosophical relevance of these debates without having to contend with complex technical arguments. This will be a major new resource for students working on logic, as well as for readers seeking a better understanding of philosophy of logic in its wider context. (shrink)

The majority of antimicrobials that are produced are administered to animals, particularly food animals. While the overall impact of antimicrobial use in animals on antimicrobial resistance in humans and the environment is unclear, it undeniably has a role. Yet, some degree of antimicrobial use in animals is necessary for animal health and welfare purposes. Balancing the benefits and risks of antimicrobial use in animals is challenging because of the complexity of the problem and limitations in available data. However, a range (...) of measures can be implemented to reduce, refine and optimize antimicrobial use in animals, with a goal of minimizing the impact on human and environmental health while maintaining necessary therapeutic use in animals. A pandemic instrument can provide the necessary foundation for the whole-of-society and whole-of government One Health approach that is required to strengthen surveillance, communication, collaboration, and action.

Se exponen precisiones en torno al concepto de cultura científica sobre la base de numerosos referentes actuales y a partir de las diferencias en su tratamiento, en el que generalmente se asume como categoría que es vinculada a las grandes masas y que, por su oficio, deben portar los individuos que se relacionan directa o indirectamente con la construcción del conocimiento científico y los resultados o salidas derivados de estos. También se propone el concepto de cultura científico investigativa que parte (...) de una intencionalidad como regularidad del pensamiento científico en el modo de actuación del sujeto consciente y desarrollador de esa categoría esencial, núcleo de capacidades transformadoras que median el pensamiento científico y la toma de decisiones en función de las demandas sociales. On the basis of current references about of scientific culture concept, the authors detailed the differences in the treatment in which it is generally assumed as a category that is linked to the masses and which, due to their profession, must have the individuals that are directly or indirectly related to the construction of scientific knowledge and the results or outputs derived from them. In addition, the concept of scientific research culture is proposed, from intentionality as a regularity of scientific thinking in the action mode of the conscious individual and developer of that essential category, a nucleus of transformative capacities that mediate scientific thinking and decision making in function of social demands.

The study intends to investigate the relationship between work stress and job insecurity, as well as technological changes and job insecurity, with job satisfaction acting as a mediator. The study was conducted among Pakistani retail industry employees using survey questionnaires distributed online and in stores. The sample was composed of 262 retail workers from the FMCG and shopping mall industries. The responses were screened using the statistical software tool SPSS, and hypotheses were examined through SMART-PLS. The findings show that work (...) stress has a strong relationship with job insecurity; additionally, the relationship appears to be statistically significant. This demonstrates that many technological changes cause high levels of job insecurity because employees fear that they will be unable to cope with the changing environment. Furthermore, the mediating mechanism of job satisfaction was found to be significant, as employees with lower levels of satisfaction reported higher levels of insecurity, aiding in the narrowing of the gap in this section of the study. The study also has practical implications because the results show that the retail industry needs to act quickly to make sure workers do not worry about losing their jobs, especially now that COVID-19 is spreading like wildfire.

Background: Mental fatigue can impact physical demands and tactical behavior in sport-related contexts. Small-sided games are often used to develop a specific sport-related context. However, the effects of mental fatigue on physical demands and tactical behaviors during soccer SSGs have not been aggregated for systematical assessment.Objective: This systematic review was conducted to compare the effects of mental fatigue vs. control conditions in terms of the total running distance and tactical behavior of soccer players during SSGs.Methods: The data sources utilized were (...) PubMed, PsycINFO, Scielo, Scopus, SPORTDiscus, and Web of Science. The study eligibility criteria were established based on PICOS: Population: healthy youth and young adult men soccer players with regular training practice and belonging to teams with regular competitions; Intervention: exposed to mental fatigue-induced protocols only before SSGs; Comparator: control conditions before SSGs; Outcomes: physical demands and tactical behavior ; Study design: counterbalanced cross-over design; and only full-text and original articles written in English.Results: The database search initially identified 111 titles. From those, six articles were eligible for the systematic review and meta-analysis. Results showed no significant effect of fatigue on total running distance and tactical behavior.Conclusions: A non-significant effect of mental fatigue on total running distance and tactical behaviors performed by soccer players during SSGs was found in this systematic review.

In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the hypothesis of conceptual (...) structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

Platón y Kant plantean un modelo “constitucional” del alma, en el que la razón y el apetito o la pasión tienen diferentes roles estructurales y funcionales en la generación de la motivación, en contraposición al común “modelo combativo,” en el que son mostrados como fuentes de motivación independientes que luchan por el control. Desde el punto de vista del modelo constitucional, podemos explicar qué hace que una acción sea diferente de un evento. Lo que hace que una acción sea (...) atribuible a una persona y, por lo tanto, lo que la hace una acción, es que surge desde la constitución de la persona y, por lo tanto, desde la persona como un todo, y no desde una fuerza que actúa sobre o en ella. Esto, a su vez, implica una explicación de lo que hace buena a una acción: lo que hace que una acción sea buena es que se delibere sobre ella y se la elija de una manera que unifique a la persona en un sistema constitucional. A través de la acción deliberativa nos constituimos como agentes unificados. La justicia platónica y el imperativo categórico de Kant se muestran como estándares normativos para la acción porque son principios de autoconstitución. (shrink)

RATIONALE AND AIMS: Total hip and knee replacements, usually, have long waiting lists. There are several prioritization tools for these kind of patients. A new tool should undergo a standardized validation process. The aim of the present study was to validate a new prioritization tool for primary hip and knee replacements. METHODS: We carried out a prospective study. Consecutive patients placed on the waiting list were eligible for the study. Patients included were mailed a questionnaire which included, among other questions, (...) the seven items of the priority tool and the Western Ontario and McMasters Universities Arthritis Index (WOMAC) specific questionnaire. The priority tool gives a score from 0 to 100 points, and three categories (urgent, preferent and ordinary). We studied the content and construct validity. We used Student's t-test or one-way analysis of variance. Correlational analysis was used to evaluate convergent and discriminate validity. RESULTS: The sample consisted of 838 patients (62.3% were female), with mean age of 70.2 years (SD 8.4). A total of 55.5% patients underwent knee replacement. Given that the tool was elaborated by patients and orthopaedic surgeons, it shows a good content validity. The priority score was statistically different (P < 0.001) among the three urgency categories created. The scores of the three WOMAC dimensions showed differences (P < 0.001) by the three urgency categories created. The correlations between the priority score and WOMAC dimensions were 0.79 (function), 0.69 (pain) and 0.51 (stiffness). The correlations between WOMAC items and items from priority tool were greater (0.47-0.69) between items measuring similar constructs than those measuring different constructs (0.27-0.49). These data are similar in both joints. CONCLUSIONS: Results support the validity of the prioritization tool to be used with patients waiting for hip or knee replacement. (shrink)

The main objective of the article is to understand the notion of power in Foucault as an action on action in a relationship of forces. In principle, the power of sovereignty and biopower in classical times are investigated. Where it is perceived that the former has negative and repressive connotations, while this one has positive and productive connotations of facts, happenings. Then, an analysis of Foucault's power is analyzed, where it is possible to verify that there is no construction of (...) a Theory of Power in Foucault, but only an ascending analysis of power, thus departing from specificity for general aspects. Finally, we will analyze the power relationship, seen as an action over action, in this action-reaction movement, there is its need, its becoming, its truth, which is the exercise of power, functioning. Thus, from the molecular to the complex composition, from the invisible to the visible, from the body to the population, power is understood, that is, power relations in the Foucaultian web.

Abordamos aquí unos aspectos, posiblemente los menos conocidos, de la dilatada vida de Fray Diego de Deza, como son los orígenes de su linaje en la gallega Terra de Deza y el afincamiento durante la segunda mitad del siglo XIV de la que fue la rama familiar de Toro, su ciudad natal. No perteneciendo a la hidalguía de mayor abolengo y riqueza de los linajes allí establecidos, sus méritos personales le labraron un futuro prometedor, primero por la cátedra docente que (...) ocupó en Salamanca y sus altas dotes como maestro y, además, por la confianza que los Reyes Católicos depositaron en él al nombrarlo preceptor del malogrado príncipe heredero don Juan, lo que le hizo emprender una envidiable carrera tanto eclesiástica como por sus servicios a la Corona. Nuestro objetivo aquí no ha sido otro que vislumbrar sus relaciones parentales y sociales, obviando su brillante cursus honorum en ese doble rol de servicio al altar y al trono. (shrink)

Mi objetivo en este texto es obtener ciertos rendimientos que sirvan para desarrollar una comprensión de la necesidad práctica dentro de la filosofía moral de Kant por medio de una discusión, principalmente, con la interpretación de Scarano. En esta última se busca establecer algún tipo de identidad entre necesidad práctica y necesidad teórica, con lo cual se reduce la primera a una forma puramente lógica, descuidando así el carácter propiamente práctico que también la constituye. Mi propuesta alternativa tiene como clave (...) la mención a la voluntad divina en la explicación por parte de Kant sobre qué significa que la ley moral sea válida para todo ente racional. Esta mención nos permite comprender, al menos en principio, que la necesidad práctica es aquella con la cual actuaría una voluntad divina de acuerdo con la ley moral. En nuestro caso, como además de la razón tenemos la inclinación como fundamento de determinación de la acción, no necesariamente actuamos de acuerdo con la ley moral, pero debemos hacerlo, de modo que la ley moral es constrictiva para nosotros.

The study of sleep and wakefulness can inform debates about the nature of consciousness. We argue that sleep and wakefulness fall along a multidimensional continuum and that inconsistencies and paradoxes with the accounts put forth by Merker et al. and Tononi can be understood in terms of a pervasive false dichotomy between these two states.

We overview the main historical and technological elements characterising the rise, the fall and the recent renaissance of the cognitive approaches to Artificial Intelligence and provide some insights and suggestions about the future directions and challenges that, in our opinion, this discipline needs to face in the next years.

La indagación del segundo Heidegger acerca del ser encuentra su maduración en la doctrina del Ereignis, un nuevo concepto «post-metafísico», según Vattimo, con el que el filósofo alemán trata de responder a la pregunta de qué es el ser una vez ha mostrado, en su primera etapa intelectual, la esencial diferenciación ontológica. El ser no es un ente, ni aquello fijo e inmutable que fundamenta lo ente. Ni de él puede decirse que es; el ser «se da». Y se da (...) al hombre en un acto de donación recíproca en la totalidad del acontecer histórico. Vattimo parte de esta idea para concluir que el ser es evento que orbita en la constelación del Ge-Stell, el destino de la época actual en cuanto forma de desocultar el ser, de desvelar la verdad, y convierte a Heidegger en precursor de la postmodernidad y de su pensiero debole.

La filosofía de los pensadores "presocráticos" ha sido abordada frecuentemente desde una perspectiva ontológica o cosmológica. El presente trabajo propone situar las consideraciones ontológicas o cosmológicas de estos pensadores en un marco más amplio, determinado por lo que el autor llama la "lógica de las retribuciones". Esta perspectiva más abarcadora tiene la ventaja de poder integrar en la exposición de las primeras filosofías de Grecia algunos textos frecuentemente desatendidos, por considerarlos puros elementos mitológicos o literarios. Desde este punto de vista (...) se abren nuevas vías para entender las relaciones entre filosofía y religión, al tiempo que se muestran las intenciones prácticas de la filosofía en sus mismos orígenes.
