El término estrés es una aportación de un médico húngaro llamado Has Selye (1907-1982). Su primera intuición sobre la existencia de este proceso psicológico se produjo mientras realizaba su rotatorio hospitalario al final de sus estudios de medicina. Observó que todos los pacientes, independientemente de la enfermedad que padecieran, presentaban unos síntomas comunes que denominó el síndrome de "simplemente estar enfermo", y que posteriormente en su tesis doctoral fue renombrado como "síndrome general de adaptación". Esto dio lugar a que el (...) resto de su vida lo dedicara al estudio y formalización del concepto de estrés. (shrink)

In this work, on the one hand, we examined the relationship between emotional intelligence (EI) and empathy and, on the other, the relationship between emotional intelligence and nonverbal sensitivity, through two independent studies. The first study analyzed the relationship between dimensions of emotional intelligence and aspects of empathy, in a sample of 856 participants who completed two measures of EI, the Trait Meta-Mood Scale (TMMS) and the Trait Emotional Intelligence Questionnaire (TEIQue), and a measure of empathy, The Interpersonal Reactivity Index (...) (IRI). The results showed a similar pattern of significant positive relations in all the EI domains with empathic Perspective-taking, and significant negative relationships with empathic Personal Distress, except for the EI domain of Attention, which had a positive relationship. Stepwise multiple regression analyses showed that the dimension that best predicted empathic Perspective-taking and Empathic Concern was the Emotionality Factor; whereas Attention best predicted empathic Fantasy; and the Self-Control Factor best predicted Personal Distress, although negatively. Gender emerged as a predictor of three empathic aspects, Fantasy, Empathic Concern, and Personal Distress, with women obtaining higher scores than men in all of them. Age was the only predictor of Fantasy, with a negative relationship. The second study involved 646 people who completed the same measures of EI as the participants of the first study and the Mini-Profile of Nonverbal Sensitivity (Mini-PONS). The results showed some significant relationships between EI dimensions and the channels and quadrants of the MiniPONS. Stepwise multiple regression analyses showed that very few EI dimensions predicted nonverbal sensitivity, with Attention obtaining the best result. Both gender and age emerged as predictors, some in unique cases, of channels, quadrants and of the total score of nonverbal sensitivity; age had a negative relationship, and women obtained higher scores than men.

A veces suceden cosas altamente traumáticas que cambian drásticamente nuestra vida, intuitivamente pensamos que ante tales circunstancias nos encontramos indefensos y que nuestra vida debe cambiar para peor, pero no necesariamente es así. Desde el siglo XIX en que surge el interés por el concepto de trauma, se entiende éste como una experiencia psicológicamente extrema, desbordante y desestabilizadora para cualquier persona. Las reacciones serían crisis de ansiedad, sintomatología depresiva e incluso cuadros de estrés postraumático.

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two (...) factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.

The aim of this study was to evaluate the neuromuscular response to an agility and repeated sprint ability test according to the level of competition in futsal players. A total of 33 players from two elite teams and one amateur team participated in the study. The participants completed an agility t-test, a 30 m-speed test, and a RSA test. A countermovement jump test and a tensiomyography test of the rectus femoris and biceps femoris of both legs were carried out before (...) and after the tests. RSA test revealed better sprint times in elite players compared to amateurs in the seven bouts, as well as in the 30 m sprint and in the agility test. In conclusion, elite players showed greater performance in the RSA test, in the 30 m tests and in the agility test compared to amateur players. The contractile properties were not a key factor in the RSA performance of the futsal players. (shrink)

Understanding how the chordate body plan originated and evolved is still controversial. The discovery by Spemann and Mangold in 1924 of the vertebrate organizer and its inductive properties in patterning the AP and DV axis was followed by a long gap until the 1960s when scientists started characterizing the molecular events responsible for such inductions. However, the evolutionary origin of the organizer itself remained obscure until very recently; did it appear together with the origin and radiation of vertebrates, or was (...) it a chordate affair? A recent study by Yu and collaborators,1 which analyses the expression of several organizer‐specific genes in amphioxus together with recent phylogenetic data that reversed the position of invertebrate extant chordates (e.g. urochordates and cephalochordates), indicates that the organizer probably appeared in early chordates. It likely had separate signalling centres generating BMP and Wnt signalling gradients along the DV and AP axis. The organizer was then lost in the urochordate lineage, most probably as an adaptation to a rapid and determinate development. BioEssays 29:619–624, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

The origin of chordates and the consequent genesis of vertebrates were major events in natural history. The amphioxus (lancelet) is now recognised as the closest extant relative to the stem chordate and is the only living invertebrate that retains a vertebrate‐like development and body plan through its lifespan, despite more than 500 million years of independent evolution from the stem vertebrate. The inspiring data coming from its recently sequenced genome confirms that amphioxus has a prototypical chordate genome with respect to (...) gene content and structure, and even chromosomal organisation. Pushed by joint efforts of amphioxus researchers, amphioxus is now entering a new era, namely its maturation as a laboratory model, through the availability of a large amount of molecular data and the advent of experimental manipulation of the embryo. These two facts may well serve to illuminate the hidden secrets of the genetic changes that generated, among other vertebrates, ourselves. (shrink)

This paper shows an analysis of some found solutions for the famous aporia of the race between Achilles and the Tortoise. As an introduction, we present the mechanical solution, to establish that it is not in the field of matters of fact where you can resolve a purely rational problem like the one raised by Zeno of Elea. And so, the main part of the article is dedicated to the mathematical solutions, which face the problem under the point of view (...) of the single, mathematical reason. There are two mathematical solutions for Zeno’s paradox. First, we attend to that which we denominate “classical” (because it is the most habitually used by mathematicians), which is based on the calculus of addiction of terms of a geometrical series in progressive decrease. The second considered solution is the one that was proposed by Russell, based upon the theory of the transfinite numbers. The analysis we have made gets us to discover that no one of those solutions can save itself from falling into logical contradictions, therefore it seems that Zeno’s problem is an authentic aporia, which, after so much time, continues challenging human intelligence. As the article’s conclusion, we suggest that the cause of the impossibility of solving Zeno’s problem is the very notion of mathematical continuum, because this notion infringes the logic of facts.

This paper analyzes the concept of alterity in the thought of Emmanuel Levinas and its importance to make a critic of the ethical ones of dialogical inspiration. As opposed to the conception of the intersubjective relations founded on in a previous community, the alterity concept shows the necessity to think the sense to us of the ethics from the other.

Este trabajo quiere responder a la demanda de quienes buscan una introducción breve pero significativa a las reflexiones de Joseph Ratzinger sobre la identidad histórica de Europa. Se trata de un estudio que, desde la perspectiva del teólogo alemán, realiza un somero itinerario por la historia político-espiritual de Europa, subrayando la cesura que constituyó el siglo XX, y que finaliza con algunas propuestas para construir una Europa con futuro. Entre éstas no conviene olvidar la luz que proviene de los extraños (...) destellos de revelación, sugiriendo un futuro ensayo de teología de la historia. (shrink)

Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in children and adolescents. People who have this disorder are characterized by presenting difficulties in the processes of sustained attention, being very active, and having poor control of their impulses. Despite the high prevalence of this disorder and the existence of various tests used for its diagnosis, few data are available regarding the usefulness and diagnostic validity of these tools. Given the difficulties that these subjects present in executive functions, (...) the aim of this study was to evaluate whether the Neuropsychological Assessment of Executive Functions battery for Children allows to establish specific profiles of executive performance for people with attention-deficit hyperactivity disorder. The sample was made up of 197 participants of both sexes, aged between 6 and 12 years age. A nonexperimental design was followed, using a comparative descriptive study method. The results indicated that the scales of phonological fluency, color path, rings, and interference are the most associated with the diagnosis of ADHD, providing data on inhibition, mental flexibility, sustained and selective attention, planning, verbal fluency, and working memory, among others. The practical implication of these results is in line with providing support in the clinical diagnosis that is carried out in children’s mental health units. In addition, the ENFEN tool can be valued as a suitable psychometric instrument in the psychoeducational field, helping professionals in a school environment to be more aware of the areas of cognitive development in which a student diagnosed with ADHD will have more difficulties and, in doing so, providing more adjusted and effective psychopedagogical measures when it comes to supporting students in their adaptation to the school environment.

Alternative splicing (AS) is a widespread mechanism with an important role in increasing transcriptome and proteome diversity by generating multiple different products from the same gene. Evolutionary studies of AS have focused primarily on the conservation of alternatively spliced sequences or of the AS pattern of those sequences itself. Less is known about the evolution of the regulation of AS, but several studies, working from different perspectives, have recently made significant progress. Here, we categorize the different levels of AS evolution, (...) and summarize the studies on evolution of AS regulation, which point to a high level of evolutionary conservation of the regulation of AS events conserved between related species. This suggests that the quantitative regulation of AS is an intrinsic part of AS function. We discuss the potential role of changes in developmental regulation of AS as an additional layer in complex gene regulatory networks and in the emergence of genetic novelties. (shrink)

La obtención de alimentos sanos y seguros requiere de técnicas de conservación inocuas para el consumidor y para el me­dio ambiente, entre las que se destaca la bioconservación. A su ca­tálogo de compuestos naturales o microorganismos, utilizados de forma habitual, la bioconservación ha incorporado recientemente los bacteriófagos y las proteínas fágicas con actividad lítica. La utilización de fagos y endolisinas en el biocontrol ofrece importantes ventajas frente a otros sistemas de conserva­ción tradicionales. Entre dichas ventajas destacan su inocuidad, especificidad y (...) versatilidad. Por otra parte, la acuciante necesidad de reducir el uso de antibióticos en la cadena alimentaria ha impul­sado la investigación basada en estos antimicrobianos con el fin de aplicarlos en producción primaria. Sin embargo, y a pesar de la gran eficacia ya demostrada en múltiples sectores, la falta de legislación de la Unión Europea sobre el uso de bacteriófa­gos junto con la necesidad de ser aceptados por los consumidores, son factores que están afectando negativamente a su implantación como bioconservantes. En este contexto, este artículo recoge los últimos resultados relacionados con este tipo de antimicrobianos en la industria agro-alimentaria, y resume los puntos clave para entender las posibilidades reales de su aplicación ante los nuevos requisitos asociados con una producción sostenible tanto desde una perspectiva económica como ambiental.

The generation of the pitch control signal in a wind turbine (WT) is not straightforward due to the nonlinear dynamics of the system and the coupling of its internal variables; in addition, they are subjected to the uncertainty that comes from the random nature of the wind. Fuzzy logic has proved useful in applications with changing system parameters or where uncertainty is relevant as in this one, but the tuning of the fuzzy logic controller (FLC) parameters is neither straightforward nor (...) an easy task. On the other hand, reinforcement learning (RL) allows systems to automatically learn, and this capability can be exploited to tune the FLC. In this work, a WT pitch control architecture that uses RL to tune the membership functions and scale the output of a fuzzy controller is proposed. The RL strategy calculates the fuzzy controller gains in order to reduce the output power error of the WT according to the wind speed. Different reward mechanisms based on the output power error have been considered. Simulation results with different wind profiles show that this architecture performs better (123.7 W) in terms of power errors than an FLC without RL (133.2 W) or a simpler PID (208.8 W). Even more, it provides a smooth response and outperforms other hybrid controllers such as RL-PID and radial basis function neural network control. (shrink)

Background: The development of professional values in nursing is directly related to quality and ethical clinical practise and may also increase practitioner and patients’ satisfaction. Some factors, such as work setting or work experience, can influence the importance granted to the professional values of nursing. Objectives: To compare in primary care nurses and hospital care nurses the importance granted to professional values and to contrast this perception as a function of professional experience. Research design, participants and research context: Descriptive cross-sectional (...) study. Participants were 380 nursing professionals from the public health system (primary care and hospital care). Three dimensions were analysed: ethics, professional expertise and professional mastery. Data were collected from January to June 2015. Ethical considerations: We obtained permission from the Ethics Committee and participants’ informed consent. Findings: Hospital care professionals attached more importance to all the values analysed, regardless of their work experience. Ethical values, such as confidentiality and respect for the person, were considered to be very important in both systems. Values related to professional expertise obtained lower scores, especially in primary care. In general, professionals with more than 20 years’ experience granted less importance to the values. Conclusion: The professional setting influenced the importance assigned to professional nursing values, and clear differences were observed between primary and hospital care. The domain of ethics was considered the most important. It is necessary to reflect on the significance attributed to professional values, especially in more expert nursing staff. (shrink)

Se analiza el feminismo como una nueva concepción de la idea de hombre. El feminismo se presenta como un movimiento alternativo que pretende superar el sesgo antropocéntrico de la filosofía y la cultura Occidental. Para comprobar esta posición de partida, se analizada el feminismo desde dos variables, la idea de sujeto y las ideas de hombre de Max Scheler. Desde la primera perspectiva se aplica una matriz fenoménico-materialista para clasificar los distintos feminismos y analizar en qué casos podría construir un (...) sujeto universal. Desde la segunda se analiza y clasifica el feminismo como un proyecto posthumanista o transhumanista, incluido en la idea pesimista de hombre. (shrink)

Pocas veces ha habido mayor afinidad entre un filósofo y un científico. Este libro (de 191 páginas) descubre cómo Julián Marías conoció a Jérôme Lejeune en 1980, y ambos resultan muy afines: los dos afirman la unicidad (calidad de único) de cada persona, algo que durante la Edad Media se reservaba a muy pocos seres de este mundo: el Sol, la Luna o la Tierra, pero no se aplicaba a cada persona, considerada como miembro de una especie única porque se (...) creía que su principio de individuación era la materia señalada por la cantidad (estos huesos y esta carne, no agotados en cada individuo). Además, se consideraba que solo había persona cuarenta días después de la concepción en el caso del varón, y noventa en el caso de la mujer. El presente libro (que traduce por primera vez al español algunos textos en francés tanto de Lejeune como de Marías y que parte de la genética moderna descubierta por Lejeune, así como de la metafísica de Marías, la cual considera "mi vida" como la realidad radical) muestra cómo estos dos grandes humanistas supieron ir a contracorriente, usando la razón y la ciencia, para proteger al no nacido.

¿Es posible ser nacionalista y cristiano a la vez? ¿Hasta qué punto se han influido y se influyen de forma mutua nacionalismo y Cristianismo, especialmente en España? ¿Debe el Cristianismo orientar acerca del nacionalismo? ¿Acaso no tiene la competencia o los suficientes recursos para hacerlo? Las respuestas a esas preguntas suelen tratarse, en general, con bastante torpeza, sin el requerido conocimiento histórico; hay muchos intereses creados a los que no interesa la verdad. Los lectores de este libro (de 292 págs.)

Tanto Tomás de Aquino como Husserl coinciden, respecto a la teoría sobre la verdad, en pensar que (debido a la adecuación) el intelecto hace una copia exacta (absoluta) de una cosa siempre idéntica (igualmente absoluta), y que gracias a ello refutan el relativismo. Pero Julián Marías, entusiasta de la verdad, critica al absolutismo y al relativismo, y piensa que ambos están basados en la verdad como adecuación. La visión que sobre la verdad tiene Marías es consecuencia de su respeto a (...) la realidad, organizada en perspectiva: esta es de la realidad, no del hombre que la mira. Por ello ninguna verdad agota la realidad. Los partidarios de la adecuación suelen aplicar su esquema mental a los objetos irreales o ideales, suponiendo que la realidad como tal, caótica para ellos por la multitud de puntos de vista diferentes, está desorganizada y es fuente de relativismo.
