Adults (more than 18 years old) are likely to reproduce the habits that they acquired during childhood and adolescence (from 6 to 16 years old). For that reason, teachers and parents have the responsibility to promote an active and healthy lifestyle in children and adolescents. Even though every school subject should promote healthy activities, Physical Education (PE) is the most important subject to foster well-being habits associated to healthy lifestyle during sport practice and other kinds of active tasks. Indeed, there (...) are many factors that influence the acquisition of healthy habits that should be taken into account when programs and activities are implemented in both educational and extracurricular context. In this sense, psychological and social factors are of utmost importance to achieve optimal experiences for an active and healthy lifestyle. However, due to the myriad of studies analyzing different factors in different contexts, there could be confusion when programs and pedagogical strategies are applied in educational or extracurricular contexts. The objective of this investigation is to analyze the state of art of the psychosocial factors which influence the engagement in physical activities and sport practice. The keywords used in this review were mainly: ‘Self-Determination Theory’, ‘motivation’, ‘Psychological need satisfaction, ‘physical activity and sport engagement’, ‘Elementary Education’, ‘Secondary Education’, ‘Physical Education’. The articles were selected according to the following criteria: (a) peer-reviewed original research published in international journals indexed in JCR or SJR, (b) published in English or Spanish, (c) about psychosocial factors which influence the physical activity and sport engagement, (b) in educational or extracurricular context. Research articles selected were found through nine databases. It was observed that physical activities and sport practice engagement are closely related to psychological factors. In particularly, intrinsic motivation was able to determine the active participation in any activity, including physical activity and sport practice during the implementation of Small-Sided Games and other kinds of pedagogical strategies (e.g., Pedagogical Models). Motivation was also closely related to flow state. Finally, these variables should be considered in order to organize effective programs to promote an active and healthy lifestyle in Physical Education classes. (shrink)

This study analyses the performance and market timing of US socially responsible (SR) mutual funds in relation to business cycle regime shifts and different grouping criteria: Ethical strategy focus, SR attributes scores and Morningstar category. Different methodologies are applied and results highlight the importance of considering specific benchmarks related to the investment style in evaluating the SR fund performance. Our results show that, in aggregate, the abnormal performance of SR funds is negative and significant in expansion periods, but no significant (...) differences are found in recession periods. When specific benchmarks are considered, performance improves in recession periods, particularly for environmental funds, those with high SR attributes scores, and funds from the nine Morningstar style box categories. Market timing of SR funds takes positive values and is partially significant. Previous evidence of negative timing after a recent financial crisis vanishes when specific benchmarks are considered. For comparative purposes the performance of conventional US mutual funds is also analysed. There are no significant differences between the performance of SR and conventional mutual funds when a fair comparison is made within the same style categories. When all the SR funds are considered, they underperform conventional funds in expansion sub‐periods, but in recession sub‐periods they perform better, although the differences observed are not significant.

The aim of this paper is to prove how what is apparently a mistake made by Plutarch, wheter deliberate or not, in his reference to the arson attack of Caesar´s soldiers in Alexandria as the end of the famous Library, show us the common sense of the term “bibliotheke” from that time up to now. Coming to this conclusion has required a detailed analysis of the Library of Alexandria since its birth applying Aristotelian doctrine to its configuration not only as (...) an organized space for books but also as an imaginary reading room from which the helenistic world of relations is established. In a second approach, we focus the attention on the change occurred in this collection with the introduction of alphabetical order and, then, with the philological activity of Callimachus. As a result of his Pinakes, the platonic concept of daimon, “guide”, became the first characteristic o a philologist or librarian. Using the information ordered in the Pinakes anybody could be a librarian and find a library anywhere. The old megále bibliotheke of Alexandría remains only with the idea of the conservation of original papyrus. This is de reason of the enigmatic sentence of Plutarch announcing the end of this situation caused by the action of the fire. (shrink)

Suicide, as one of the leading causes of death for the adolescent population, both in Chile and globally, remains a complex and elusive phenomenon. This research studies the association between positive and negative affect in relation with suicidal ideation and suicidal attempt, given that affectivity is a fundamental basis on which people make evaluations on their satisfaction with life. First, it examines the reliability, structure, and validity of Watson’s positive and negative affect scale (PANAS) scale in a representative random sample (...) of Chilean high school students (N= 4,568). The scale evidences strong reliability coefficients and a confirmatory factor analysis, excluding one positive (excited) and one negative (nervous) item. The scale shows a satisfactory goodness of fit. Secondly, it investigates the association of PANAS positive and negative affect scores with suicidal ideation as well as reported attempt in adolescents, controlling for the potential effect of age and sex (N= 420 high school students). Low positive and high negative affect, but not sex and age, show a significant association with suicidal ideation. Suicidal ideation totally mediates the association of affect with suicide attempt, as expected. Results are discussed regarding prevention and it considers how positive and negative affect can be relevant as indicators for prevention and treatment using widely available technology. (shrink)

The emergent Coronavirus Disease 2019 caused by the Severe Acute Respiratory Syndrome Coronavirus 2 could produce a maternal immune activation via the inflammatory response during gestation that may impair fetal neurodevelopment and lead to postnatal and adulthood mental illness and behavioral dysfunctions. However, so far, limited evidence exists regarding long-term physiological, immunological, and neurodevelopmental modifications produced by the SARS-CoV-2 in the human maternal-fetal binomial and, particularly, in the offspring. Relevant findings derived from epidemiological and preclinical models show that a MIA (...) is indeed linked to an increased risk of neurodevelopmental disorders in the offspring. We hypothesize that a gestational infection triggered by SARS-CoV-2 increases the risks leading to neurodevelopmental disorders of the newborn, which can affect childhood and the long-term quality of life. In particular, disruption of either the maternal or the fetal cholinergic anti-inflammatory pathway could cause or exacerbate the severity of COVID-19 in the maternal-fetal binomial. From a translational perspective, in this paper, we discuss the possible manifestation of a MIA by SARS-CoV-2 and the subsequent neurodevelopmental disorders considering the role of the fetal-maternal cytokine cross-talk and the CAP. Specifically, we highlight the urgent need of preclinical studies as well as multicenter and international databanks of maternal-fetal psychophysiological data obtained pre-, during, and post-infection by SARS-CoV-2 from pregnant women and their offspring.

La "yesería" constituye uno de los elementos decorativos más característicos de nuestra arquitectura medieval. La imagen que hoy tenemos de La Alhambra, de la Sinagoga del Tránsito, y de tantos otros palacios y conventos, se debe a ese barato elemento constructivo que logró crear la misma apariencia de lujo de las telas o el marfil. Como hemos podido estudiar en nuestro artículo del número anterior (Al-Qantara, XX, 275-297), en el palacio de Ruy López Dávalos de Toledo se conserva uno (...) de los conjuntos más fascinantes del siglo XIV, el cual nos ha llevado a preparar estas páginas sobre la técnica de la yesería medieval.

Corned stucco represents one of the most characteristic elements of Spanish medieval architecture. The image that we have of the Alhambra, of Samuel Halevi's synagoge —el Tránsito— and of countless other palaces and monasteries is due to this cheap construction material which could imitate the luxurious quality of silk textiles and ivories. In our previous article {Al-Qantara, XX, 275-97), we showed that Ruy López Dávalos de Toledo's palace conserves an important group of carved stuccos. In this paper, we discuss (...) its technique of fabrication. (shrink)

In Mexico, the Productive Organization Program for Indigenous Women (POPMI) seeks the empowerment of productive capacities in indigenous women. Our study analyzes POPMI outreach, focusing our attention on women beneficiaries who present a high degree of social exclusion and multidimensional poverty in the State of Veracruz.

Under an observational, transversal, and descriptive design, the study analyze the degree of adjustment of the perceptions of fear of failure as a mediating variable of the estimated relationship between sporting commitment and the appearance of burnout in young handball players in a competitive context. The sample included a total of 479 youth category handball players selected to compete in the Spanish Regional Championships. The age range was 16 −17 years old. With regard to the years of experience variable, 85.4% (...) stated that they have more than 5 years of experience at the federated handball player level. The Spanish version of Performance Failure Appraisal Inventory, Inventory Athletes Burnout Revised, and Sport Commitment Questionnaire were used to assess fear of failure. The correlation patterns evidence that commitment is negative and significantly associated with emotional exhaustion, depersonalization, and fear of failure and positively associated with reduced sense of personal accomplishment. In the standardized direct effect, negative and significant effects were observed between commitment and fear of failure, fear of failure with emotional exhaustion and depersonalization, and on the contrary, a negative and significant effect was observed between fear of failure and reduced sense of personal accomplishment. The evaluated athletes reflect a positive psychological disposition, show pride in having been selected by their territorial teams and reflect a high desire to show their sporting qualities. Despite the emergence of cognitive-emotional processes associated with fear of failure, this has been observed to protect the sense of self-fulfillment through sport effort, although it also has impacts on further emotional exhaustion and loss of value of sport effort.

Norms have been widely enacted in human and agent societies to regulate individuals’ actions. However, although legislators may have ethics in mind when establishing norms, moral values are only sometimes explicitly considered. This paper advances the state of the art by providing a method for selecting the norms to enact within a society that best aligns with the moral values of such a society. Our approach to aligning norms and values is grounded in the ethics literature. Specifically, from the literature’s (...) study of the relations between norms, actions, and values, we formally define how actions and values relate through the so-called value judgment function and how norms and values relate through the so-called norm promotion function. We show that both functions provide the means to compute value alignment for a set of norms. Moreover, we detail how to cast our decision-making problem as an optimisation problem: finding the norms that maximise value alignment. We also show how to solve our problem using off-the-shelf optimisation tools. Finally, we illustrate our approach with a specific case study on the European Value Study. (shrink)

Este trabajo surge a partir de la investigación general de las técnicas hidropónicas teniendo en cuenta sus ventajas y desventajas para de esta forma poder encontrar aquel factor determinante a través de una comparación de técnicas hidropónicas que permitan clasificarlas y escoger la mejor opción que genere menos impacto ambiental negativo y demuestre ser más productivo en los entornos urbanos. Adicionalmente, un factor determinante en las ciudades es su espacio limitado por lo que la mejor opción también deberá incluir un (...) óptimo manejo del espacio que permita a casi cualquier individuo poder aplicarlos desde su entorno sin recurrir a excesivas modificaciones. Como principal resultado se escogió a la Hidroponía recirculante como método predominante por los excelentes resultados que se obtienen con relación a los demás, adicionalmente, este puede ser fácilmente aplicado en los ambientes urbanos por su versatilidad y buen manejo de recursos.

RESUMEN Partiendo de la discusión del concepto de carne, en este trabajo analizo la común estructura ontológica/biopolítica que comparten los animales humanos y no humanos. Para ello me sirvo de los feminismos materiales y utilizo los hallazgos teóricos del feminismo animalista. También examino la noción de "encierro" en tanto concepto biopolítico que produce un nuevo tipo de ser vivo. Todo ello para, en último lugar, articular un sentido positivo del concepto de encarnación que permita construir comunidad animal. ABSTRACT In this (...) article, I analyze the common ontological/biopolitical structure shared by human and non-human animals, starting out from the discussion of the concept of flesh. To that effect, I resort to material feminisms and to the theoretical findings of animal rights feminism. I also examine the notion of "enclosure" as a biopolitical concept that produces a new kind of living being. All of this serves to formulate a positive sense of the concept of incarnation that allows for the construction of a animal community. (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)

La publicación del trabajo doctoral de Carlos Arturo López sacude desde la raíz el relato convencional de lo que ha sido la filosofía en Colombia. En un regreso “a los textos mismos” publicados entre 1892 y 1910, atendiendo a los criterios de escritura válidos en ese momento y lugar, López propone describir las condiciones históricas de un “relieve específico de la escritura filosófica” (38).

RESUMEN La concepción de la persona se ha trasladado a una discusión sobre la teoría republicana de la autodeterminación política. Hito fundamental es lo "político", introducido por J. Rawls para definir una región artificial, no metafísica, de la organización de la vida humana en sociedad. Es un concepto normativo para definir ciudadanía que incluye una concepción moral del hombre. Se sostiene que, en la articulación de este concepto y sus nociones asociadas de autonomía plena y razonabilidad de los agentes, el (...) constructivismo político recoge la concepción del hombre como sujeto de sentidos, tema central del comunitarismo. ABSTRACT The conception of person has shifted to the discussion on the republican theory of political self-determination. A fundamental milestone was the concept of the "political", introduced by J. Rawls to define an artificial, non-metaphysical region of organization of human life in society. It is a normative concept to define citizenship, which includes a moral conception of human beings- The article claims that, in the articulation of this concept and its associated notions of full autonomy and rationality of agents, political constructivism takes up the conception of human being as a subject of meanings, which is central to communitarianism.

Typically, existentialist analyses of “America” have been limited to North America (more specifically, the United States). I argue that developing an adequate framework for existentially analyzing America requires a turn to Mexican existentialism. In Emilio Uranga’s and Jorge Portilla’s writings, we discover new conceptual tools for understanding Americanness as such. These thinkers help us imagine an account of American being that does not restrict itself to the United States by using the concepts of existentialism to describe the crises their neighbors (...) to the north as well as they themselves face. American existence has been historically characterized by a convergence (oftentimes clash) of disparate races, ethnicities, languages, cultures, religions, and identities. As history unfolded, this convergence led to various existential crises across the Americas. Whereas the US American way of life is marred by a blustering, naïve, and purposeless misuse of freedom that disregards the other, the existential crisis the Mexican lives is characterized by “accidentality” and “zozobra.” Despite these important differences, all existentialists, and the Mexican existentialists of the Hyperion Group especially, remind us that there is a common way to overcome the various existential crises plaguing the Americas, and that is to exercise freedom in a purposeful, communally conscious manner.

Resumen El objetivo principal de este artículo es analizar el comportamiento de cinco periódicos españoles que trataron ampliamente un acto de habla proferido por el rey de España Juan Carlos I el día 19 de abril de 2012. Se trata de una petición de disculpas al pueblo español por la participación en un safari africano: “Lo siento mucho. Me he equivocado y no volverá a ocurrir”. La importante crítica social hizo que la figura del monarca fuera cuestionada en (...) amplios sectores de la vida pública española. El hecho, excepcional por la naturaleza de quien lo protagonizó, adquirió por ello una gran relevancia mediática. Los periódicos contemplados para este estudio colaboraron en la restauración de la imagen real, una vez que fueron mayoritariamente aceptadas las disculpas. Se propone, por todo ello, el concepto de cortesía ideológica como un mecanismo estratégico fomentado a través del lenguaje periodístico. (shrink)

Resumen Los mensajes de Navidad del rey Juan Carlos I constituyen una de las pocas ocasiones en las que el jefe del Estado español se dirige a los españoles a través de la televisión. El objetivo principal de este artículo es analizar estos textos emitidos por el monarca en el período de su reinado. Estamos ante unos mensajes que los pronuncia el representante de la institución de la Corona, pero que no tienen el correspondiente refrendo legal. Son costumbres (...) y tradiciones aceptadas por todos. El estudio se lleva a cabo desde la perspectiva del análisis del discurso y desde la semiótica de la comunicación, para poner de relieve cómo el texto es utilizado con fines ideológicos para consolidar la imagen de la Monarquía, a la vez que la estructura del Estado. Las figuras del ethos y de la auctoritas reales se ponen de relieve cuando se quiere afianzar la imagen del monarca y de la institución que encarna. Los mensajes siguen el modelo de la oratoria clásica y se utilizan como medio para comentar, persuadir y arbitrar un marco de convivencia en España en la que el rey juega un papel de moderador entre el Estado y la ciudadanía.

In this article, I argue that, contrary to scholarly consensus, Antonio Caso draws inspiration from important principles and ideas from Kant’s philosophy in his critique of positivism. I first examine the prima facie textual reasons why someone might believe that Caso and Kant are philosophical enemies. To contradict this notion, I proceed by noting and developing three core ideas that the two share in common. First, Caso and Kant are both ardent critics of dogmatic philosophizing. Second, both Caso and Kant (...) carve out special room for intuition in their respective accounts of cognition, resisting the idea that the understanding has a more prominent role in the formation of knowledge. Third, Kant’s doctrine of aesthetic judgment paves the way for Caso’s de-intellectualized aesthetics. In the end, we see that Kant and Caso are closer to being philosophical friends than enemies.

Frecuentemente se ha interpretado la filosofía política de Julien Freund como una lectura decisionista y polemocéntrica de lo político de fuertes ecos schmittianos. Sin entrar en sus raíces intelectuales, pretendo justificar el sentido que asume en su obra la adhesión a la tradición realista, distanciándose sin embargo de una interpretación tanto cratológica como nihilista de la política que tendiera a reducir los asuntos públicos al solo dominio estratégico de los medios. Entiendo, al contrario, que el realismo de Freund coincide con (...) su perspectiva “mesocrática” o, si se prefiere, “liberal” en un sentido “árquico”, no minarquista o neutralizador. Esto exige un cambio de enfoque en el estudio de su obra que evite fundamentalmente dos extremos: la reducción de lo político a la sola dialéctica del mando y la obediencia, a costa de la integración de todos sus factores, y la sobrevaloración del problema de los medios respecto de los fines.

La experiencia filosófica de Pablo Posada Varela queda lejos de ser un currículo de filósofo académico. Cuando el verdadero filósofo escribe está movido siempre por motivaciones éticas, para fortalecer el sentido que se busca. Un sentido en contacto permanente con su φρενός, una «inteligencia frenética» al margen de los espasmos del cogito cartesiano y su posterior narcosis. Tampoco ese sentido tiene que ver con la búsqueda de la verdad de su perpetuum mobile. En Pablo Posada Varela hay una verdadera topología (...) del sentido, ideas del sentido fuera del sentido.

El propósito de esta entrada es hacer notar la inquietud de Marc Richir en sus Méditations phénoménologiques (1992: 61), de que una estética fenomenológica era más necesaria que nunca aun moviéndonos en cualquier horizonte, imposible de hecho, como a veces pueda serlo el lenguaje en busca del sentido; pero esta entrada se enmarca en una parrhesía de lenguaje más bien débil centrada en lo antiguo donde el arte, (tomando como referencia o inicio (ὑπάρχω) las tragedias griegas en el plano de (...) la mímesis, en correspondencia con la Einfühlung, identificación fenomenológica, la identidad de la obra en las tragedias), tanto si imita sólo con lenguaje (arte de la sofística), como si se habla de la verdadera creación, la tragedia, sobrepasa las etiquetas de cualquier logos en permanente lucha: trágico, intencional, pasional o trascendental; no encontramos ninguna mitología semántica que lo identifique en una cerca intencional, por su pérdida espontánea, o lo recupere en un sentido estético incoativo, en una fase (φάσις), o forma que dejará ver o no según le dé la luz; Platón no lo llega a cazar en el Sofista (al arte de la sofística), porque transgrede cualquier conducta, desde dentro y desde fuera, es decir, tanto si es un disimulo pasional del poeta (catarsis antigua), como si lo consideramos desde el marco de Aristóteles en el cierre artístico clásico de la tragedia (symmetría) en la experiencia generada en el espectador como un fenómeno estético insuficiente (catarsis trágica).

With the advent of the cloud computing model allowing a shared access to massive computing facilities, a surging demand emerges for the protection of the intellectual property tied to the programs executed on these uncontrolled systems. If novel paradigm as confidential computing aims at protecting the data manipulated during the execution, obfuscating techniques (in particular at the source code level) remain a popular solution to conceal the purpose of a program or its logic without altering its functionality, thus preventing reverse-engineering (...) on the program even with the help of computing resources. The many advantages of code obfuscation, together with its low cost, makes it a popular technique. This paper proposes a novel methodology for source code obfuscation that can be used together with other traditional obfuscation techniques, making the code more robust against reverse engineering attacks. Three program complexity metrics are used to define three different single-objective combinatorial optimization versions of the problem, which are solved and analysed. Additionally, three multi-objective problems are defined, those considering each of the selected metrics together with the program execution time, in order to avoid strong obfuscations penalizing the performance. The goal of the defined problems is to find sequences of LLVM optimizations that lead to highly obfuscated versions of the original code. These transformations are applied to the back-end pseudo-assembly code (i.e., LLVM Intermediate Representation), thus avoiding any further optimizations by the compiler. Classical genetic algorithms (GAs) are used to solve the studied problems, namely a basic cellular GA for the single-objective problems and the popular NSGA-II for the multi-objective ones. The promising results show the potential of the proposed technique. (shrink)

Los escritos de Jürgen Habermas han despertado en España un interés notable y sostenido en el tiempo. Han ejercido una fuerte influencia intelectual no solo en los círculos académicos, sino también en amplios sectores de la esfera pública, algo sorprendente teniendo en cuenta su complejidad y su carácter más bien técnico. En sus textos los lectores españoles han encontrado elementos que sintonizan constructivamente con los cambios acaecidos en su propia sociedad y en el mundo. Como argumento de autoridad o como (...) referencia a rebatir, Habermas se ha hecho habitual en la filosofía y en la teoría social pensada y escrita en español. En este artículo se tratará de presentar los diversos contextos que posibilitaron la acogida de sus ideas, así como los principales actores que con sus trabajos y reflexiones han protagonizado la propagación de su pensamiento.

The purpose of this article is making a critical revision of the field of communication –understood as a field of research and reflection– and the way its existence has been tried to be legitimated since the postwar period. Our stance holds that, even though it is possible to find relatively linear and continuous narratives to understand communication, what is regarded here is reaching comprehension of the fragmentation and language games brought together in it. Besides, the core problem does not rely (...) on the consolidation of a linear and scientific epistemological narrative, but on the manner discourse is articulated, giving place to such narratives turning around their political charges and not the supposed scientific value attributed to them.
