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

El uso de las Tecnologías de la información y la comunicación ha permitido introducir mejoras en la forma como se desarrollan los procesos de enseñanza y aprendizaje, así como los procesos propios a la gestión y administración de las actividades académicas. Sin embargo, el índice de adopción de estas herramientas es reducido en cobertura y en profundidad. No obstante, para el uso de la herramienta Teams hay que detallar las ventajas y desventajas encontradas y finalizar con conclusiones en base a (...) las experiencias personales.

Burnout is characterized by emotional exhaustion and caused by exposure to excessive and prolonged stress related to job conditions. Moreover, burnout is highly prevalent among health care professionals. The aim of this study is, first, to examine the mediating role of social support over the effect of burnout in health care professionals and, second, to explore potential gender differences. A convenience sample of 1,035 health professionals from Ecuador, including 608 physicians and 427 nurses, was surveyed using the Maslach Burnout Inventory, (...) Social Support Survey, and General Health Questionnaire as measures of burnout, social support, and general health, respectively. Social support was found to mediate the negative effects of burnout on health regardless of gender. Differences across the three dimensions of burnout and health are further discussed, along with their implications for designing effective burnout interventions for health care professionals in Ecuador.

The dual career allows elite athletes to attain their maximum competitive and academic performance, but the COVID-19 pandemic hindered their development and changed their perception of the importance given to the sporting and educational environment. For this reason, the aim of the present study was to determine the differences in the motivations and perceived barriers, the importance given to academic qualifications, and the perception of the dual career from a multifactorial perspective, of elite athletes according to sex, type of sport (...) practiced, job performance, time of sports career, type of athlete, and type of scholarship received. A total of 100 student-athletes participated in the research study by completing the “Perceptions of dual career student-athletes” questionnaire. The results showed that athletes from individual modalities and those who did not receive any scholarships described more barriers. In addition, women studied more because they enjoyed it ; athletes from individual modalities studied to work later ; athletes who do not work perceived a greater influence between study and sports performance ; at the beginning and at the best stage of their sports career, a greater influence of academics on performance was perceived ; and athletes who considered themselves professionals, and athletes who did not receive any scholarships, reported that the conciliation between sports and academic life was difficult. The results obtained point to the importance of dual career scholarships for student-athletes, as well as the need for the programs implemented for these athletes to consider sex, sport modality or type of scholarship granted.

The idea of merit is at the core of intense contemporary debate related to social justice in general and meritocracy in particular. In this paper, I aim to differentiate the notion of merit from two other notions with which it is often mistakenly identified, namely the concepts of talent and achievement. Here, I define “merit” as the value of an action that 1) is imputable to a subject‘s free conduct, 2) implies some sort of effort, and 3) is oriented towards (...) a good. Merit so understood is a valuable phenomenon considered from various perspectives, and therefore the subject who has it deserves to be properly recognized. But, more importantly, this merit is valuable in a sense that is different from the value attached to talent and achievement. We should therefore try to recognize the three of them according to their specificity. I conclude by signaling some problems and limitations associated with the idea of merit that, on the one hand, contribute to the aforementioned confusion and, on the other hand, show that the principle of merit must not be absolutized to the detriment of other forms of value (including talent and achievement).

El objetivo del trabajo consiste en revisar dos versiones del argumento que concibe a la averiguación de la verdad como un factor que confi ere legitimidad al ejercicio de la función jurisdiccional penal: la de Ferrajoli y la de Laudan. Se sostiene que su estudio minucioso puede proporcionar bases racionales para decidir sobre la conveniencia de suscribir un garantismo extremo o uno de carácter más mesurado. Esta decisión cobra relevancia en el contexto de la discusión acerca de cuáles son las (...) características más apropiadas de los modelos teóricos del proceso penal. (shrink)

El artículo revisa las aportaciones más trascendentes que Jordi Ferrer ha hecho a la tradición racionalista de la prueba jurídica y evalúa críticamente el limitado papel que, desde su óptica, le corresponde desempeñar a la epistemología en la discusión general sobre los estándares de prueba apropiados para las distintas ramas del derecho. Más específicamente, se analiza la irrelevancia que Ferrer parece atribuir a dicha disciplina –o el silencio que debe guardar–, respecto del establecimiento del estándar de prueba deseable en materia (...) penal. Se concede que, en efecto, le corresponde al pueblo tomar la decisión de qué estándar implementar. No obstante, se sostiene, ello no impide que la epistemología incida en el proceso de formación de dicha decisión mediante la realización de observaciones, el ofrecimiento de argumentos y la propuesta de metodologías adecuadas, con miras a que aquella se tome en un contexto mejor informado y sea lo más racional posible. Se ilustra esta posición haciendo referencia al proyecto de epistemología jurídica de Larry Laudan. (shrink)

In contrast to most Western countries, routine offer of prenatal screening is considered problematic in the Netherlands. The main argument against offering it to every pregnant woman is that women would be brought into a moral dilemma when deciding whether to use screening or not. This paper explores whether the active offer of a prenatal screening test indeed confronts women with a moral dilemma. A qualitative study was developed, based on a randomised controlled trial that aimed to assess the decision-making (...) process of women when confronted with a test offer. A sample of 59 women was interviewed about the different factors balanced in decision-making. Participants felt themselves caught between a need for knowledge and their unwillingness to take on responsibility. Conflict was reported between wishes, preferences and ethical views regarding parenthood; however, women did not seem to be caught in a choice between two or more ethical principles. Participants balanced the interests of the family against that of the fetus in line with their values and their personal circumstances. Therefore, we conclude that they are not so much faced with an ethical dilemma as conflicting interests. We propose that caregivers should provide the opportunity for the woman to discuss her wishes and doubts to facilitate her decision. This approach would help women to assess the meaning of testing within their parental duties towards their unborn child and their current offspring. (shrink)

In this paper, the structure of a southeastern Spanish population was studied for the first time with respect to its inbreeding patterns and its relationship with demographic and geographic factors. Data on consanguineous marriages from 1900 to 1969 were taken from ecclesiastic dispensations. Our results confirm that the patterns and trends of inbreeding in the study area are consistent with those previously observed in most non-Cantabrian Spanish populations. The rate of consanguineous marriages was apparently stable between 1900 and 1935 and (...) then sharply decreased since 1940, which coincides with industrialization in Spain. A marked departure from Hardy-Weinberg expectations in the ratio of first cousin to second cousin marriages in the study population was observed. The high levels of endogamy and its significant steadiness throughout the twentieth century is noteworthy. Accordingly, our results show that exogamous marriages were not only poorly represented but also that this reduced mobility suggests that the choice of a mate was preferentially local. We found higher mobility in M22 with respect to M33 cousin mating. The relationships between population size and consanguinity rates and inbreeding fit power-law distributions. A significant positive correlation was observed between inbreeding and elevation. Many Spanish populations have experienced a prolonged and considerable isolation across generations, which has led to high proportions of historical and local endogamy that is associated, in general, with high \ values. Thus, assessing genomic inbreeding using runs of homozygosity in current Spanish populations could be an additional pertinent strategy for obtaining a more refined perspective regarding the population history inferred from the extent and frequency of ROH regions.

The interdisciplinary spring school “Language, music, and cognition: Organizing events in time” was held from February 26 to March 2, 2018 at the Institute of Musicology of the University of Cologne. Language, speech, and music as events in time were explored from different perspectives including evolutionary biology, social cognition, developmental psychology, cognitive neuroscience of speech, language, and communication, as well as computational and biological approaches to language and music. There were 10 lectures, 4 workshops, and 1 student poster session. Overall, (...) the spring school investigated language and music as neurocognitive systems and focused on a mechanistic approach exploring the neural substrates underlying musical, linguistic, social, and emotional processes and behaviors. In particular, researchers approached questions concerning cognitive processes, computational procedures, and neural mechanisms underlying the temporal organization of language and music, mainly from two perspectives: one was concerned with syntax or structural representations of language and music as neurocognitive systems (i.e., an intrapersonal perspective), while the other emphasized social interaction and emotions in their communicative function (i.e., an interpersonal perspective). The spring school not only acted as a platform for knowledge transfer and exchange but also generated a number of important research questions as challenges for future investigations. (shrink)

Motivation in schizophrenia has been a key research aim for several decades. Motivation is a very complex process underlying negative symptoms that has been assessed and identified using very different instruments and terminologies. This study provides a comprehensive overview of the growing literature production and highlights an extensive set of variables to better understand the study of motivation. Electronic databases were searched in order to compile relevant studies of motivation in individuals with schizophrenia. The initial search identified 3,248 potentially interesting (...) records, and of these, 161 articles published between 1956 and 2017 were finally included. Information such as year of publication, journal, country, and number of authors was codified. Variables related to sample characteristics, methodological aspects, and motivational terms were also extracted. The results revealed a significant growth trend in literature production, especially since the 2000s, with reward as the main term studied. In addition, questionnaires were identified as the preferred instrument to assess motivation in patients with schizophrenia. Other aspects such as country of publication, authors, journals of publication, and co-citation network analysis were also examined. The discussion offers recommendations for future research.

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

In this paper we propose an approach to multi-source belief revision where the trust or credibility assigned to informant agents can be revised. In our proposal, the credibility of each informant represented as a strict partial order among informant agents, will be maintained in a repository called credibility base. Upon arrival of new information concerning the credibility of its peers, an agent will be capable of revising this strict partial order, changing the trust assigned to its peers accordingly. Our goal (...) is to formalize a set of change operators over the credibility base: expansion, contraction, prioritized, and non-prioritized revision. These operators will provide the capability of dynamically modifying the credibility of informants considering the reliability of the information. This dynamics will reflect a new perception of trust assigned to the informant, or extend the set of informants by admitting the addition of new informant agents. (shrink)

This study examines the way that consent is reported for participation in school-based research involving children or young people aged from 5 to 16 years. Databases containing descriptions of research identified during systematic reviews were surveyed to determine to what extent consent is sought, and from whom, and to see whether reporting varied by study characteristics such as the age of participants, the country in which the research was carried out, research design and substantive area of study. Of a total (...) of 489 studies in school settings involving children or young people, less than a third reported seeking consent. Only one in seven sought consent from children or young people themselves. Consent was reported significantly more frequently in studies sourced from health promotion reviews, when compared to those sourced from education reviews. Codes of practice indicate that researchers should seek consent from research participants. This study demonstrates that these principles are often not reflected in practice. (shrink)

Previous research addressing the association between leisure and happiness has given rise to the hypothesis that informal social activities might contribute more to happiness than solitary activities. In the current study, we tested how the two types of leisure—social and solitary—contribute to a person’s subjective sense of well-being. For the empirical estimate, we used four consecutive quarters of data collected from 533 people over the age of 16, from 13 Tsimane’ hunter-farmer villages in the Bolivian Amazon. Results suggest that only (...) social, not solitary, leisure has a positive and statistically significant association with subjective well-being. The association between solitary leisure and subjective well-being was negligible or negative. Future research should focus on emic definitions of social and solitary time, for solitary time might not always be equivalent to leisure and productive group activities might substitute for social leisure.

Argumentation represents a way of reasoning over a knowledge base containing possibly incomplete and/or inconsistent information, to obtain useful conclusions. As a reasoning mechanism, the way an argumentation reasoning engine reaches these conclusions resembles the cognitive process that humans follow to analyze their beliefs; thus, unlike other computationally reasoning systems, argumentation offers an intellectually friendly alternative to other defeasible reasoning systems. LogicProgrammingisacomputationalparadigmthathasproducedcompu- tationallyattractivesystemswithremarkablesuccessinmanyapplications. Merging ideas from both areas, Defeasible Logic Programming offers a computational reasoning system that uses an argumentation engine (...) to obtain answers from a knowledge base represented using a logic programming language extended with defeasible rules. This combination of ideas brings about a computationally effective system together with a human-like reasoning model facilitating its use in applications. (shrink)

As an alternative to linear and unidimensional perspectives focused mainly on either organic or psychological processes, the enactive approach to life and mind—a branch of 4-E cognitive theories—offers an integrative framework to study mental disorders that encompasses and articulates organic, sensorimotor, and intersubjective dimensions of embodiment. These three domains are deeply entangled in a non-trivial manner. A question remains on how this systemic and multi-dimensional approach may be applied to our understanding of mental disorders and symptomatic behavior. Drawing on Gilbert (...) Simondon’s philosophy of individuation, we provide some enactive conceptual tools to better understand the dynamic, interactive, and multi-dimensional nature of human bodies in mental disorders and psychopathological symptoms. One of such tools cursiva is sense-making, a key notion that captures the relational process of generating meaning by interacting with the sociomaterial environment. The article analyzes five aspects related to sense-making: temporality, adaptivity, the multiplicity of normativities it involves, the fundamental role of tension, and its participatory character. On this basis, we draw certain implications for our understanding of mental disorders and diverse symptoms, and suggest their interpretation in terms of difficulties to transform tensions and perform individuation processes, which result in a reduction of the field of potentialities for self-individuation and sense-making.
