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)

Introduction: Connectedness to nature is a concept that reflects the emotional relationship between the self and the natural environment, based on the theory of biophilia, the innate predisposition to the natural environment. However, the biophobic component has largely been ignored, despite, given its adaptive functional role, being an essential part of the construct. If there is a phylogenetic component underlying nature connectedness, biophilic and/or biophobic, there should be evidence of this record from early childhood. The main aim of this study (...) is therefore to describe the emotional attributions identified in five-year-olds. Methodology: Two studies were conducted. In the first, 94 children expressed their concept of nature and made basic emotional attributions to a set of 60 images of natural and urban environments, using a software designed for the study. In the second, 39 children repeated the procedure and provided explanations for their responses. Results: The main results show that, in general, children use both positive and negative emotions, which may be related to a three-dimensional model of emotional attributions to nature. The most widely attributed emotion is happiness, for the images of both natural and built environments. However, fear is the second most common attribution. The role of happiness could be explained by a feeling of security and familiarity that the habitat of the built environment contributes to, while the importance of fear in nature could show an adaptive response of the fear of wild nature in children. This interpretation could be confirmed when analyzing specifically the emotional attributions to the natural environment, classifying the images according to biological and ecosystemic criteria. Thus, for example, more emotional attributions are explained by the "pleasantness" attributed to primary producers and landscapes (e.g. flora), versus attributions of "harm" to the images of secondary and tertiary consumers (e.g. hunters). Conclusions: These results provide evidence in favor of a didactic procedure to study emotional attributions to images of nature in preschool children. They suggest the incorporation of biophobia as an important adaptive factor in connectedness to nature and a tripartite emotional hypothesis based on the valences of the attributed emotions.

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of each referee (...) during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

El presente libro constituye una interesante propuesta para enfrentar el estudio del pasado de una manera distinta a la historiografía tradicional, a la cual se la ha criticado muchas veces por su escritura compleja y por la escasa empatía que las investigaciones generan con el lector que no es especialista en este tipo de conocimientos. Es por esto que, y al igual que lo realizado en XIX Historias del siglo diecinueve chileno, los autores del texto presentan una serie de artículos (...) en los que.. (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)

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)

El objetivo del presente documento es analizar las ideas de espacio y tiempo en Hume y mostrar la peculiaridad de dichas ideas, puesto que no provienen de la experiencia y, por el contrario, son necesarias para ella. Para ello analizaré los argumentos que presentó Hume al abordar dichas ideas, con el fin de iluminar y proporcionar una comprensión diferente a la tradicional lectura que se hace de las nociones de espacio y tiempo de Hume, la cual está inmersa por la (...) postura newtoniana del espacio y el tiempo. Sin embargo, esta tarea no se puede realizar de manera aislada a las investigaciones de su tiempo sobre estas nociones, ni tampoco aislarla del sistema del que hace parte, es decir el sistema epistemológico humeano. Así, el primer paso será abordar a grandes rasgos las principales posturas de la época sobre este tema y, en segundo lugar, abordaré el problema en torno a las ideas de espacio y tiempo en Hume, que dividiré en dos partes: la lectura fuerte que se hace sobre estos temas; es decir, la lectura tradicional y la lectura débil que es la que propone Kemp Smith y es sobre la que sustentaré mi tesis: las ideas de espacio y tiempo en Hume son a priori.

This article has as main objective, to present the problems on Hume’s version about believes and its interpretation. This has been of great importance not only on Humean philosophy, but also in the subsequent philosophical thinking due to the fact that his proposal is about the impossibility of reasoning on the matters of facts. Hence, the belief would supply the emptiness of reasoning, and it would fundament and be the motor of our actions in the absence of reasoning. The main (...) objective is to show belief not as a lived idea, as Hume presents it, but as a propositional attitude that moves us towards action. Therefore, belief can be understood as two different but closely related ways: as a propositional fact (we accept what we believe as true) and as a disposition to act. (shrink)

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)

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.

Analisa essa leitura e oferece, a partir do próprio Foucault, uma interpretação alternativa, que aponta para algumas imprecisões cometidas por Rorty, em sua interpretação. Conclui com um comentário sobre a conversação proposta.

You think you're human. But what does that mean? How can humanity be defined? Felipe Fernandez-Armesto takes us on an enlightening and provocative journey through the history of humankind to reveal the challenges to our most fundamental belief - that we are, and have always been, human. Fernandez-Armesto investigates advances in artificial intelligence and genetics, and asks what these mean for the future of human values, human rights, and the defence of human dignity. The book illustrates how our concept (...) of humankind has changed over time and how our current understanding of this has been shaken by new challenges from science and philosophy. (shrink)

ObjectiveThis study aimed to analyze the influence and measurement of the relationship and interaction between the elderly lifestyles after the appearance of the SARS-CoV-2 variant and the factors analyzed comprised life satisfaction levels, social relationships, and daily-life activities.MethodsThe study population was ≥ 65 in Castile-La Mancha. The research design was quantitative and arose from primary data collected via an ad hoc survey carried out through the Computer Assisted Telephone Interview system by randomly stratified sampling. The sample size was made up (...) of 1,065 cases, and the participants were selected through a random sampling stratified by gender quotas, age, province, and habitat size.ResultsThe results obtained revealed two main lifestyles, from which a notable behavioral change in personal relationships led to infer toward alternative lifestyles.ConclusionNotwithstanding the variation in lifestyles of the elderly after the pandemic, certain relationships remained unaltered. Thus, from the analyzed variables, relatives and friends relationships were scarcely influenced by the supervened incident. (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.

Negar el libre albedrío implica que el ser humano no es libre por naturaleza, sino que puede llegar a serlo mediante un uso adecuado de su inteligencia; libertad que solo la consiguen los “sabios”. Por eso, cuando Spinoza entiende la democracia como la forma de gobierno que mejor defiende la libertad, esto vale para los “sabios”, pero no para el vulgo, que solo mediante el miedo y la esperanza es conducido a obrar según los dictados de la razón. ¿No será (...) esta indeseable consecuencia la que le impidió terminar su Tratado Político, precisamente cuando se aprestaba a estudiar la democracia?

En este artículo se estudia el papel jugado por diferentes órdenes religiosas con vistas a la instalación de alguna de sus comunidades en el antiguo cenobio agustino de Nuestra Señora de Regla sito en la localidad gaditana de Chipiona en el marco del proceso de restauración de las órdenes religiosas vivido en España tras la supresión de las mismas, sobre todo con la llegada al trono español del rey Alfonso XII en 1875, proceso que se vio complicado por la instalación (...) en nuestro país de las comunidades religiosas expulsadas de Francia a partir de 1880. Se analiza especialmente el papel desempeñado por los franciscanos misioneros españoles y los monjes benedictinos franceses de las abadías de Solesmes y Ligugé. (shrink)
