Este artículo presenta un enfoque de la creatividad de la acción que, sin renunciar a los logros alcanzados por diversas tradiciones sociológicas, apuesta por la imaginación como clave filosófica complementaria para continuar su desarrollo. Se diagnostica primero el lugar restringido que la creatividad ha tenido en la sociología de la acción; se ofrece después una precisión de “creatividad”, a partir de la noción de “contingencia”; ulteriormente se propone un esquema general para situar la imaginación en distintos niveles de la acción; (...) y, finalmente, se muestran tres caminos de desarrollo posible, según se haga de la imaginación un fenómeno de la conciencia, del lenguaje o de la psique.

ObjectiveCOVID-19 caused a complete stop in non-professional sports. The use of face masks for team sports is not a widely used measure in non-professional sports. The study aimed to evaluate the perception about using the mask and the adaptation difficulties related to training and competition in team sports following the FISICOVID-DXTGALEGO protocol.MethodsSeven hundred eighty-seven handball players from the Galician Handball Federation were followed during their return to participation after months of confinement through an electronic questionnaire of perception and experience on (...) the use of a mask.ResultsThere is an excellent adaptation to the mask in training and competition with medium and high correlations. The 86,41% of players reported an adaptation to the mask in 3 weeks with a three times a week training frequency. The negative opinion on the mask was drastically reduced after use. The 80,44% of players considered the use of a mask as an essential measure to resume competitions.ConclusionsIt is very feasible to adapt to training and compete with a mask in a short period. The use of a mask following these protocols changed previous opinions on the disadvantages of the mask during training and competition. (shrink)

In this article we present symmetric diffusion networks, a family of networks that instantiate the principles of continuous, stochastic, adaptive and interactive propagation of information. Using methods of Markovion diffusion theory, we formalize the activation dynamics of these networks and then show that they can be trained to reproduce entire multivariate probability distributions on their outputs using the contrastive Hebbion learning rule (CHL). We show that CHL performs gradient descent on an error function that captures differences between desired and obtained (...) continuous multivariate probability distributions. This allows the learning algorithm to go beyond expected values of output units and to approximate complete probability distributions on continuous multivariate activation spaces. We argue that learning continuous distributions is an important task underlying a variety of real‐life situations that were beyond the scope of previous connectionist networks. Deterministic networks, like back propagation, cannot learn this task because they are limited to learning average values of independent output units. Previous stochastic connectionist networks could learn probability distributions but they were limited to discrete variables. Simulations show that symmetric diffusion networks can be trained with the CHL rule to approximate discrete and continuous probability distributions of various types. (shrink)

Here, we report on a quasi-experimental study to explore the applicability and perceived benefits of the CRAFT program, which is based on mindfulness, yoga, positive psychology, and emotional intelligence, to improve higher education student musicians’ health and well-being during the lockdown. A subset of student musicians at a Higher Conservatory of Music in Spain followed the CRAFT program during the academic year 2019/2020, 1 h per week as part of their curriculum. Students enrolled in CRAFT-based elective subjects formed the CRAFT (...) program group, while other students represented the control group. The onset of the national lockdown elicited by the COVID-19 pandemic occurred halfway through the program, which was subsequently delivered in an online format. We administered an online survey to explore the effect that the exposure to the CRAFT program had in terms of how participants dealt with various health and well-being concerns arising from the COVID-19 lockdown. There was a significantly higher proportion of proactive participants in the CRAFT program group, 92%, than in the control group, 58%, in terms of implementing practices to improve their health and well-being during the lockdown. Additionally, significantly more participants acknowledged perceived benefits from their practices in the CRAFT program group, 78%, than in the control group, 52%. Among proactive participants, yoga/meditation was the most implemented in the CRAFT program group, followed by exercise, and other yoga/meditation practices, whereas in the control group, exercise and Alexander technique-based practices were the most applied. In the CRAFT program group, the highest rate of perceived benefits was from yoga/meditation CRAFT-based practices, 51%, followed by exercise, 32%, and other yoga/meditation practices, 27%, whereas in the control group, benefits were reported by 29% of exercising participants and 16% for those having practiced the Alexander technique. A similar pattern was observed when excluding participants with previous yoga/meditation experience. This study revealed how participants can independently apply learned skills from the CRAFT program in response to a naturally occurring life event of unprecedented global impact, suggesting that previous exposure to mindfulness and yoga is likely to have a beneficial effect on how young adults react towards exceptionally stressful conditions.

This study details the methodological process for creating a tool for the identification of COVID-19 potential contagion situations in sports and physical education before, during, and after practice and competition. It is a tool that implies an educational and methodological process with all the agents of the sports system. This tool identifies the large number of interactions occurring through sports action and everything that surrounds it in training, competition, and organization. The aim is to prepare contingency protocols based on an (...) exhaustive analysis, risk detection, and proposal of contingency measures trying to reduce the residual risk to a minimum. In the second part, the results of the implementation of this tool in the sports system of Galicia (Spain) are shown. The technicians have changed their perceptions about the coronavirus transmission in sports. They highlight the problem for returning to sports participation for athletes under 18 years in the pandemic context. (shrink)

During the last decade, Network Science has become one of the most active fields in applied physics and mathematics, since it allows the analysis of a diversity of social, biological and technological systems [24]. From the diversity of applications of Network Science, in this Opinion paper we are concerned about its potential to analyse one of the most extended group sports, Football (soccer in U.S. terminology) [29], since it allows addressing different aspects of the team organization and performance not captured (...) by classical analyses based on the performance of individual players. The reason behind relies on the complex nature of the game, which, paraphrasing the foundational paradigm of complexity sciences “can not be analysed by looking at its components (i.e., players) individually but, on the contrary, considering the system as a whole” or, in the classical words of after-match interviews “it’s not just me, it’s the team”. The recent ability of obtaining datasets of all events occurring during a match, including the position of the players and the interactions between them has opened the door to new kind of studies where it is possible to analyse and quantify the behaviour of a team as a whole, together with the role of a single player [17]. Under this framework, the organization of a team can be considered as the result of the interaction between its players, creating a network based on passes. In this way, we can create passing networks, which are directed (i.e.,... (shrink)

This study attempts to analyse the relationship between two key psychological variables associated with performance in sports - Self-Determined Motivation and Competitive Anxiety - through Bayesian Networks analysis. We analysed 674 university students/athletes from 44 universities that competed at the University Games in México, with an average age of 21 years (SD = 2.07) and with a mean of 8.61 years’ (SD = 5.15) experience in sports. Methods: Regarding the data analysis, first a CHAID algorithm was carried out to determine (...) the dependence links between variables, and then a Bayesian networks was developed. The validation of the BN revealed AUC values ranging from 0.5 to 0.92. Subsequently, various instantiations were performed with hypothetical values applied to the “bottom” variables. Results showed two probability trees that have extrinsic motivation and amotivation at the top, while the anxiety/activation due to worries about performance was at the bottom of the probabilities. The instantiations carried out support the existence of these probabilistic relationships, demonstrating their scarce influence on anxiety about competition generated by the intrinsic motivation, and the complex probabilistic effect of introjected and identified regulation regarding the appearance of anxiety due to worry about performance.

The aim of the present study was to assess the impact of past traumatic war experiences on preadolescents in the Gaza Strip, which could be useful for psychological intervention with current and future child victims. Participants were 521 preadolescents from United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) schools, aged 11 and 13 years old. Sections I to IV from Iraqi Version-Arabic of Harvard Trauma Questionnaire was used to assess trauma experiences and Post-Traumatic Stress (...) Disorder (PTSD). The results show that the preadolescents in the Gaza Strip witnessed the destruction of their homes and the murder of family members and friends. A quarter of the individuals assessed either suffered torture or witnessed others undergoing it, including sexual assaults. Almost half of them experienced a lack of food and clean water. The traumatic and torture experiences seriously affected preadolescents’ mental health as 26.29% met criteria for the diagnosis of PTSD. The data analysis revealed two PTSD modalities, with the severity of impact depending on whether social implications were involved. Further research is required to check whether these two modalities fit to PTSD and complex PTSD. Understanding the effects of past wars on preadolescents in Gaza and distinguishing between different PTSD types could enhance comprehension of the impacts of current attacks on child victims. It can also aid in determining the type of intervention needed to minimize the impact on the mental health of Palestinian youth, enhancing their resilience through psychological and social support.

The aims of the present study were to analyse people’s natural ability to discriminate between true and false statements provided by people with intellectual disability (IQTRUE = 62.00, SD = 10.07; IQFALSE = 58.41, SD = 8.42), and the differentiating characteristics of such people’s statements using criteria-based content analysis (CBCA). Thirty-three people assessed 16 true statements and 13 false statements using their normal abilities. Two other evaluators trained in CBCA evaluated the same statements. The natural evaluators differentiated between true and (...) false statements with somewhat above-chance accuracy, even though error rate was high (38.19%). That lay participants could not effectively discriminate between false and true statements demonstrates that such assessments cannot be considered useful in a forensic context. The CBCA technique did discriminate at a better level than intuitive judgements. However, of the 19 criteria, only one significantly discriminated. More procedures specifically adapted to the abilities of people with intellectual disabilities are thus required. The presence of structured production, quantity of details, characteristics details and unexpected complications increased the probability that a statement would be considered true by non-expert evaluators. The classification made by the non-expert evaluators was independent of the participants’ IQ. A big data analysis is performed in search for better classification quality. (shrink)

Assessing physical fitness has emerged as a proxy of the health status of children and adolescents and therefore as relevant from a public health point of view. DAFIS is a project included in Plan Galicia Saudable of the regional government of Galicia. DAFIS consists of an on-line software devoted to record the results of a standard physical fitness protocol carried out as a part of the physical education curriculum. The aims of this study were: to obtain normative values of physical (...) fitness of the Galician school population evaluated in the DAFIS project, and to identify a reduced number of components and tests able to capture a significant amount of the variability in the physical fitness of children and adolescents. From an initial sample of 27784 records, 15287 cases were considered after filtering. Generalized Additive Models for Location, Scale and Shape were used for obtaining percentile curves and tables for each sex. Furthermore, a principal components analysis was performed, selecting the number of components by applying the Kaiser’s rule and selecting a subset of variables considering the correlation between each variable and the components. Percentile curves and normative values are reported for each test and sex. Physical fitness was better in boys than in girls throughout age groups, except for flexibility that was consistently higher in girls. Two main components were detected throughout age groups: the first one representing body composition and partially cardiorespiratory fitness and the second one muscular fitness. For boys and girls, waist to height ratio had the highest correlations with the first component in four out of six age groups. The highest correlation with the second component, was most frequently observed for the handgrip test both in boys and girls. This study provides evidence about the utility of school community actions like DAFIS aimed to track the health-related fitness of children and adolescents. The results suggest that fat mass distribution and muscular performance concentrate a high proportion physical fitness variance. (shrink)

This book examines influential conceptions of sport and then analyses the interplay of challenging borderline cases with the standard definitions of sport. It is meant to inspire more thought and debate on just what sport is, how it relates to other activities and human endeavors, and what we can learn about ourselves by studying sport.

Este artigo começa com uma apresentação breve do pensamento de Levinas sobre o sujeito visto a partir duma relação abstracta pré-original, como subjectividade imediatamente para-o-outro, an-arquicamente separada, rejeitando, assim, qualquer ideia de comunidade baseada numa totalidade. Na segunda parte, pela explanação dos temas do "Terceiro" e da "Justiça", faz-se a transição da subjectividade incomparável para a condição do sujeito como membro da sociedade, procurando deduzir, depois, algumas consequê'ncias para a concepção e prática da sociedade e da politica, traços dum pensamento (...) do social implícito nas análises de Levinas, mas não sistematicamente tratado por ele. /// Ce travail commence par une présentation de la pensée de Levinas sur le sujet, envisagé, sur la base d'une relation abstracte pré-originelle, comme subjectivité immédiatement pour l'autre, an-archiquement séparée, rejetant ainsi toute idée de communauté basée sur la totalité. Dans la seconde partie, par l'explication des themes du "Tiers" et de la "Justice" s'opere la transition de la subjectivité incomparable vers la condition du sujet comme membre de la société; on cherche ensuite à tirer quelques conséquences pour la conception et la pratique de la société et de la politique, c'est-à-dire, les traits d'une pensée du social implicite dans les analyses de Levinas, bien que non systematiquement développée chez lui. /// Accordint to Levinas, Husserl's thought exemplifies de paradigm of the philosophical tradition's tendence to conceive the conscience as intentional, active, and theoretical; the conscience determines the object that it encounters before it by giving the object a sense. For Levinas, on the contrary, the "I" that encounters the "Other" is essentially passive, for the "I" is in a relation of subordination to the "Other" and receives his sense from this very relation. But, in spite this opposition to Husserl's position, Levinas considers himself a follower of the spirit and letter of phenomenology. (shrink)

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

In einem Brief an Christiaan Huygens aus dem Jahre 1679 schlägt Leibniz eine neue von der Cartesischen Algebra verschiedene Characteristica geometrica vor. Dieser Entwurf wurde von einigen Wissenschaftshistorikern als ein Vorläufer der Analysis situs oder Topologie betrachtet. Im Jahre 1846 erhielt Graßmann einen Preis, der ausgesetzt worden war für die Konstruktion eines geometrischen Kalküls, der dem Leibnizschen ähnlich sein sollte. Im folgenden kritisierte ich die heute gemeinhin vertretene Auffassung, die Geometnsche Analyse von Graßmann sei die legitime mathematische Weiterentwicklung der geometrischen (...) Konzeptionen von Leibniz. Zunächst breite ich einige wenig bekannte historische Fakten bezüglich Leibniz und Graßmann aus und dann gehe ich dazu über, Kritik an Graßmanns Lektüre des Leibnizschen Textes zu üben. Die Frage nach dem wissenschaftlichen Wert der Gedanken, die Leibniz Huygens gegenüber äußert, möchte ich jedoch bis zur bald zu erwartenden Publikation zahlreicher Leibniz-Texte zu diesem Thema offen lassen.

According to its quietist readings, skepticism can be dissolved by demonstrating that the notion of ‘absolute objectivity’ is confused. The dissolution of this confusion is supposed to lead us to acquiesce in our finite and plain everyday life without being bothered anymore about the supposed need for objective knowledge. In contrast, I want to propose a transformative reading of skepticism according to which the philosophical practice of skepticism can be ‘epistemically transformative’. To this end, I will transpose L.A. Paul's notion (...) of ‘epistemically transformative experience’ from decision theory to the realm of philosophical practice and argue that the modern skeptical problem of an external standpoint can evoke transformative experiences that lead to a new, albeit non-propositional, insight into the finitude of the human condition.

"Le philosophe chilien Javier Agüero Águila a consacré ses recherches à la psychanalyse, à la philosophie française contemporaine - avec une attention toute particulière à la pensée de Jacques Derrida -, à la « philosophie politique » : la violence, la démocratie et les droits de l'homme, l'hospitalité, la communauté et l'extranéité, la marginalité mais encore l'héritage, la mémoire, l'oubli, le pardon, etc. C'est autour du pardon que ce livre s'organise, engageant un débat sur le processus chilien de transition (...) et de démocratisation mis en oeuvre après la dictature militaire de Pinochet" (4ème de couv.).

Scepticism and negative theology are best understood not as theoretical positions, but rather as forms of philosophical practice that performatively undermine our knowledge claims or our seeming understanding of God. In particular, I am arguing that both scepticism and negative theology invoke the failure of the attempt to understand the absolute, be it God or the notion of absolute objectivity. However, with reference to L. A. Paul’s notion of epistemically transformative experience, I am arguing that we still understand something about (...) the absolute through the experience of failing to think it. This, of course, is a non-propositional form of understanding, and I am arguing that there is something about the finitude of the human condition that can only be understood through a transformative philosophical experience with respect to the absolute.

An l-hemi-implicative semilattice is an algebra $$\mathbf {A} = $$ A= such that $$$$ is a semilattice with a greatest element 1 and satisfies: for every $$a,b,c\in A$$ a,b,c∈A, $$a\le b\rightarrow c$$ a≤b→c implies $$a\wedge b \le c$$ a∧b≤c and $$a\rightarrow a = 1$$ a→a=1. An l-hemi-implicative semilattice is commutative if if it satisfies that $$a\rightarrow b = b\rightarrow a$$ a→b=b→a for every $$a,b\in A$$ a,b∈A. It is shown that the class of l-hemi-implicative semilattices is a variety. These algebras provide (...) a general framework for the study of different algebras of interest in algebraic logic. In any l-hemi-implicative semilattice it is possible to define an derived operation by $$a \sim b := \wedge $$ a∼b:=∧. Endowing $$$$ with the binary operation $$\sim $$ ∼ the algebra $$$$ results an l-hemi-implicative semilattice, which also satisfies the identity $$a \sim b = b \sim a$$ a∼b=b∼a. In this article, we characterize the commutative l-hemi-implicative semilattices. We also provide many new examples of l-hemi-implicative semilattice on any semillatice with greatest element. Finally, we characterize congruences on the classes of l-hemi-implicative semilattices introduced earlier and we characterize the principal congruences of l-hemi-implicative semilattices. (shrink)

Researchers have iterated that the future of synthetic biology and biotechnology lies in novel consumer applications of crossing biology with engineering. However, if the new biology’s future is to be sustainable, early and serious efforts must be made towards social sustainability. Therefore, the crux of new applications of synthetic biology and biotechnology is public understanding and acceptance. The RASVaccine is a novel recombinant design not found in nature that re-engineers a common bacteria to produce a strong immune response in humans. (...) Synthesis of the RASVaccine has the potential to improve public health as an inexpensive, non-injectable product. But how can scientists move forward to create a dialogue of creating a ‘common sense’ of this new technology in order to promote social sustainability? This paper delves into public issues raised around these novel technologies and uses the RASVaccine as an example of meeting the public with a common sense of its possibilities and limitations.

The Coal Seam Gas extraction industry is developing rapidly within the Surat Basin in southern Queensland, Australia, with licenses already approved for tenements covering more than 24,000 km2. Much of this land is used for a broad range of agricultural purposes and the need for coexistence between the farm and gas industries has been the source of much conflict. Whilst much research has been undertaken into the environmental and economic impacts of CSG, little research has looked into the issues of (...) coexistence between farmers and the CSG industry in the shared space that is a farm business, a home and a resource extraction network. We conducted three workshops with farmers from across a broad region undergoing CSG development to explore farmers’ perceptions of some of the issues arising from large scale land use change. Workshops explored the importance of place identity and landscape aesthetics for farmers, farmers’ acceptance and coping with change, and possible benefits from off-farm income. We found that farmers believed that place identity was not well understood by CSG staff from non-rural backgrounds and that farmers struggled to explain some concerns because of the different way they interpreted their landscape. Furthermore, high staff turnover, and the extensive use of contractors also impacted on communications. These factors were the cause of much frustration and farmers felt that this has led to severe impacts on mental health and wellbeing. Farmers felt that a change in culture within the CSG companies will be required if engagement with farmers is to improve and that efforts to employ local people in these communications was helping this. The workshops also identified a range of issues perceived by farmers arising from increased traffic volumes, impacts to mental health and wellbeing, place identity and loss of water resources for farmers. Finally, it was suggested that scientists and agricultural industry groups will need to work closely with farmers to develop understanding of these emerging issues and to develop solutions that are timely and relevant.

This study analyzes the most important predictors of acceptance of social network sites in a sample of Chilean elder people. We employ a novelty procedure to explore this phenomenon. This procedure performs apriori segmentation based on gender and generation. It then applies the deep learning technique to identify the predictors by segments. The predictor variables were taken from the literature on the use of social network sites, and an empirical study was carried out by quota sampling with a sample size (...) of 395 older people. The results show different predictors of social network sites considering all the samples, baby boomer males and females, silent males and females. The high heterogeneity among older people is confirmed; this means that dealing with older adults as a uniform set of users of social network sites is a mistake. This study demonstrates that the four segments behave differently, and many diverse variables influence the acceptance of social network sites. (shrink)

L’article traite de la relation entre l’homme et la loi chez Spinoza. Une première partie porte sur la question de savoir si l’individu doit toujours observer les lois. Dans la seconde, sous la conduite du Traité politique, nous passons à une perspective collective et on analyse la pensée de Spinoza sur la puissance de la multitude face aux lois. À la fin, on tire quelques conclusions pour la vie d’aujourd’hui.
