This article states that research in skill acquisitionand executionhas underestimated the relevance of some features of attention. We present and theoretically discuss two essential features of attention that have been systematically overlooked in the research of skill acquisitionandexecution. First, attention alters the appearance of the perceived stimuli in an essential way; and second, attention plays a fundamental role in action, being crucial for solving the so called ’many-many problem’, that is to say, the problem of generating a coherent behavior byselecting (...) between many inputs and many potential outputs. We discuss the importance of these features for skill acquisition in sport. We also suggest empirical ways to assess the precise impact of taking them into consideration and at the same time we propose important implications for training derived from the ideas discussed in the paper.

The large number of sensors and actuators that make up the Internet of Things obliges these systems to use diverse technologies and protocols. This means that IoT networks are more heterogeneous than traditional networks. This gives rise to new challenges in cybersecurity to protect these systems and devices which are characterized by being connected continuously to the Internet. Intrusion detection systems are used to protect IoT systems from the various anomalies and attacks at the network level. Intrusion Detection Systems can (...) be improved through machine learning techniques. Our work focuses on creating classification models that can feed an IDS using a dataset containing frames under attacks of an IoT system that uses the MQTT protocol. We have addressed two types of method for classifying the attacks, ensemble methods and deep learning models, more specifically recurrent networks with very satisfactory results. (shrink)

El objetivo es conocer las circunstancias y tratamiento judicial de asesinatos por violencia de género. Se plantea el diagnóstico forense de muerte, se exponen resultados de la investigación realizada por Genovés et al. en 2018 sobre150 casos de muerte por violencia de género en Andalucía, se plantea un posible patrón de conducta basado en la teoría de los pensamientos obsesivos y rumia silenciosa. Los resultados muestran una violencia anunciada, sin trastornos mentales graves, los asesinatos se mantienen constantes en el tiempo, (...) la violencia empleada suele ser excesiva en comparación con otras muertes, el instrumento más usado es arma blanca, el agresor no se esconde, no suele arrepentirse, la calificación ha sido de asesinato en un 79%, concurriendo alevosía en un 91% de los casos, la indefensión de la víctima es buscada y utilizada por el agresor, el domicilio familiar es el lugar donde más asesinatos se producen. Se aprecia una evolución positiva en la aplicación del derecho. Es necesaria la perspectiva de género en la Justicia. (shrink)

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.

Aunque debería parecer evidente, la necesaria relación entre Universidad y verdad se ve con frecuencia obscurecida por las tendencias relativistas y por la primacía de lo práctico y lo útil propias de nuestra época. Sobre este trasfondo y para redescubrir y calibrar la importancia de la verdad como misión esencial de la Universidad, el artículo intenta describir en primer lugar la situación cultural presente en relación con la verdad; indaga, en un segundo momento, en un sentido de verdad que se (...) enmarca en el orden del amor —y no sólo del pensamiento—; y finalmente justifica por qué la Universidad sólo puede ser tal en la medida en que se dedica a buscar, encontrar y comunicar la verdad en una tensión y con un ímpetu que tienen que darse precisamente en el orden del amor.

Psychological flexibility is a key concept of acceptation and commitment therapy. This factor has been linked with psychological wellbeing and associated factors, such as quality of life, in cancer patients. These and other positive results of acceptation and commitment therapy in cancer patients found in previous research could be enhanced by using mhealth tools. A three-arm randomized superiority clinical trial, with a pre-post-follow-up repeated measures intergroup design with a 1:1:1 allocation ratio is proposed. A hundred and twenty cancer patients will (...) be randomly assigned to one of the following interventions: face-to-face ACT + mobile application, face-to-face ACT, and Waitlist control group. The primary expected outcome is to observe significant improvements in psychological flexibility acceptance and action questionnaire- II in the face-to-face ACT + app group, after comparing baseline and post-treatment scores, and the scores will remain stable in the two assessment points, 3 and 6 months after the intervention. Secondary expected outcomes are significant increasing scores in quality of life and post-traumatic-growth, and significant decreasing scores in anxiety and depression, insomnia and fatigue at the same assessment points. Also, it is expected that the scores of this group will be higher than the scores of the face-to-face ACT group and the waitlist control group. This study aims to assess the efficacy of a combined intervention for psychological flexibility and associated symptoms in cancer patients. The results of this protocol may help to consider the use of acceptation and commitment therapy and mhealth applications in cancer settings as a valid therapeutic choice.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT05126823].

Grounded theory, a research method born out of the social sciences field, offers a flexible technique that allows simultaneous data collection and processing. Researchers using this method immerse themselves in an area of study, focusing their observations on the data and taking into consideration not only their own interpretations, but also those of the other subjects involved, in order to strengthen their understanding of the social phenomena under examination. This text briefly describes the concept of grounded theory and uses concrete (...) examples to illustrate how data are analysed from the standpoint of the stereotype as an object of study. La teoría fundamentada, nacida al interior de las ciencias sociales, es un método de investigación que posee una técnica flexible y que realiza simultáneamente la recolección y el procesamiento de los datos. En este método, el investigador se encuentra inmerso en el campo de estudio y sus observaciones se abocan al dato, considerando tanto su interpretación como la de los otros sujetos implicados, con la finalidad de fortalecer la comprensión del fenómeno social investigado. En este texto se describe brevemente la teoría fundamentada y cómo se analizan los datos mediante ejemplos concretos, que se presentan a partir del estereotipo como objeto de estudio. (shrink)

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)

It is sometimes claimed that we perceive people’s mental states in their expressive features. This paper clarifies the claim by contrasting two possible readings, depending on whether expression is conceived relationally or non-relationally. A crucial difference between both readings is that only a non-relational conception of expression ensures direct access to other minds. The paper offers an argument for a non-relational conception of expression, and therefore for the view that we directly perceive people’s mental states in their expressive features.

Histamine is a multifunctional biogenic amine with relevant roles in intercellular communication, inflammatory processes and highly prevalent pathologies. Histamine biosynthesis depends on a single decarboxylation step, carried out by a PLP-dependent histidine decarboxylase activity (EC 4.1.1.22), an enzyme that still remains to be fully characterized. Nevertheless, during the last few years, important advances have been made in this field, including the generation and validation of the first three-dimensional model of the enzyme, which allows us to revisit previous results and conclusions. (...) This essay provides a comprehensive review of the current knowledge of the structural and functional characteristics of mammalian histidine decarboxylase.

The study of corporate social responsibility has been the object of much research in recent decades, although there is a need to continue investigating its benefits as a marketing tool. In the current work we adopt a multi-dimensional perspective of social responsibility, and we carry out market research to determine the perceptions of users of mobile telephone services about economic, legal, ethical and social aspects of their operating companies. With these data we determine the structure and components of the concept (...) of social responsibility. Subsequently, this is related with the overall evaluation of the service and loyalty by means of a model of structural equations, in order to determine the influence of corporate social responsibility on these concepts, and hence its benefits as a commercial tool.

Resumen El presente estudio investiga la opción cristiana por la virginidad en el pensamiento de Clemente de Alejandría. En nuestro autor no se encuentra una doctrina organizada sobre la virginidad cristiana, sin embargo, resulta sorprendente que si se estudian estos comentarios aislados de forma conjunta, se puede descubrir de forma clara y certera el pensamiento del maestro de Alejandría sobre la virginidad dentro del cristianismo. En este estudio, las citas textuales de las obras de Clemente de Alejandría servirán de referencia (...) y nos guiarán en el desarrollo de su visión sobre la virginidad cristiana.The present study investigates the Christian option for virginity in the thought of Clement of Alexandria.

Clemente de Alejandría fundó la filosofía cristiana demostrando que fe y filosofía son verdaderamente complementarias. Nacido a mediados del siglo II, inauguró la convergencia y alianza entre el cristianismo y la cultura griega. Sus obras poseen un valor inestimable dentro de la literatura eclesiástica y de la filosofía cristiana de los primeros siglos de la Iglesia. El presente estudio aborda desde la antropología filosófica el pensamiento de Clemente de Alejandría sobre el matrimonio cristiano. Es cierto que el matrimonio no constituye (...) uno de los temas centrales en las obras del autor cristiano, no obstante, dedicó gran parte del tercer libro de los Stromata a refutar doctrinas heréticas surgidas en torno al matrimonio. Este trabajo presenta una reflexión de tipo filosófico sobre los textos que se encuentran en las obras de Clemente de Alejandría en las que fundamenta su visión sobre el matrimonio. La finalidad, características, dignidad del matrimonio así como las segundas nupcias son algunas de las cuestiones que se tratan en este estudio desde la antropología filosófica. (shrink)

This paper defends a Wittgenstein-inspired conception of the nature of mind and self-knowledge. Thus, it is claimed that the mind is to be conceived as expressive behaviour; and that knowledge of one’s own mind is not to be thought of as a matter of first-person access, i.e. a special sort of access available to oneself alone, but rather as a matter of ordinary access, similar to other people’s. It is also argued that this conception does not undermine the distinctness of (...) the first-person perspective, including the asymmetry with the third-person perspective, which should be construed semantically, rather than epistemically. As a result, an alternative to contemporary conceptions of mind and self-knowledge is provided. (shrink)

Resumen El autor distribuye este trabajo en los siguientes apartados: plantea la diferencia entre el concepto de desarrollo y de progreso, consciente de que después de estos cincuenta años, con la evolución tanto de la economía como de las ideologías, y después de una gran crisis social y financiera, es necesario distinguir conceptual-mente y en la praxis estos dos términos; situamos la reflexión en el horizonte de la agenda 2030. Desde esta perspectiva estudia la propuesta de PP sobre el desarrollo (...) y la evolución y dinamismo de este pensamiento a través de las encíclicas sociales posteriores hasta nuestros días dedicando un apartado especial a su relación con la ecología integral. Finalmente, a modo de conclusión, presenta los principios que fundamentan la gradualidad del desarrollo.The author distributes this work in the following sections: he points out the difference between the concept of development and progress, aware that after these fifty years, with the evolution of both economy and ideologies, and after a great social crisis and financial, it is necessary to distinguish conceptually and praxis these two terms; we place the reflection on the horizon of the 2030 agenda. From this perspective, he studies the proposal of Populorum progressio on the development and evolution and dynamism of this thought through the social encyclicals that have been up until now, devoting a special section to its relation with integral ecology. Finally, by way of conclusion, it presents the principles underlying the gradual development. (shrink)

This article takes as its starting-point that a viable account of concept acquisition must be ontogenetically sound, and analyses in detail two alternative accounts of concept acquisition, one conceptualist and the other non-conceptualist, concluding that the conceptualist account is to be preferred.

The aim of the present study was to determine statistical differences in a set of badminton competition matches in five different modalities with regard to competition level (Group Phase versus Eliminatory Phase). Data from 453 sets (125 in men’s singles; 108 sets in women’s singles; 77 sets in men’s doubles; 73 in women’s doubles and 70 in mixed doubles) from the RIO 2016 Olympics Games were recorded and classified in two groups of variables to analyse variables related to match (5) (...) and set (15). A descriptive analysis and univariate test (Mann Whitney U) for non-parametric data were conducted. The results show in men’s and women’s singles all the variables related to match were higher in the Elimination Phase than in the Group Phase (p<0.01). In Sets 1 and 3, the longest set duration, rally and average rally were found in the Elimination Phase than Group Stage (p<0.05). In women’s singles, these differences were also recorded in Set 2. For doubles, the results are more stable among groups. Men’s doubles had a longer duration of the match and set (set 1 and set 2) (p<0.01), and also scored highest for average rally strokes (set 1 and set 3) (p<0.05) and shuttles used in the Elimination Phase versus the Group Phase along the match (p<0.01). In women’s doubles, more shuttles were used in a match in the Elimination than in the Group Phase. Moreover, the same results are established for Set 2, including for average rally. Mixed doubles saw no match going to three sets. However, the greatest differences showed a longer rally and average rally being registered in the Elimination than in the Group Phase. In conclusion, the timing factors of the badminton singles and doubles games were different in the Elimination and Group Phases. This information may help players and coaches prepare and administer different types of workouts or, more specifically, competition schedules adapted to the characteristics of modern badminton.

There is a recent popular reconstruction of Wittgenstein's thinking about animal minds, according to which animals and humans share a set of expressive abilities, prior to, and independent of, the onset of linguistic-cum-conceptual abilities; a reconstruction that in turn entails a duality of expression and linguistic-cum-conceptual abilities, in adult humans. This paper contends that the reconstruction is implausible and at odds with Wittgenstein's thinking, regarding both the developing minds of children and the minds of non-linguistic animals. Instead, it argues that (...) Wittgenstein's thinking is shaped by an anthropological outlook, according to which linguistic abilities signal the existence of a distinctive human form of life, within which animals do not belong, but into which children are progressively introduced. As a result, there is neither a shared set of expressive abilities in animals, children and adult humans; nor a duality of expression and linguistic-cum-conceptual abilities in humans. (shrink)

Entrepreneurship has undoubted social value as it contributes to socio-economic development of the context where entrepreneurship takes place. When the entrepreneurial activity is undertaken among especially vulnerable groups in the labor market, the multiplying effect of this value is made explicit in society, in general, and in the collective of people with disabilities, in particular. The objective of this research study is to explore under which conditions this happens through the analysis not only of the relationship between the competencies that (...) PWDs attribute to themselves and their development of the entrepreneurial activity but also of that between entrepreneurship and certain conditions that potentially create value by increasing the autonomy among this collective. A quantitative methodology based on the analysis of the survey carried out on a sample of 224 entrepreneurs with physical, sensory, or organic disabilities throughout Spain has been used. According to the results, entrepreneurs with disabilities have a higher self-evaluation competency. Furthermore, significant results concerning the link between the form of autonomous cohabitation of this collective and entrepreneurship have been obtained. (shrink)

The objective of this paper is to discuss the nature of nonconceptual, as opposed to conceptual, states and their content, by exploring the suggestion that the distinction between the conceptual and the nonconceptual be mapped onto the distinction between the linguistic and the nonlinguistic. This approach gives special relevance to our intuitions about the cognitive relationship between small children and adults, especially regarding the acquisition of concepts, in the course of normal cognitive development. Assuming that there is a developmental challenge (...) to be met, the paper considers both the conceptualist and nonconceptualist strategies used to meet it; and concludes that conceptualism is a more satisfying option.

According to expressivism about avowals, the meaning of typical self-ascriptions of mental states is a matter of expressing an attitude, rather than describing a state of affairs. Traditionally, expressivism has been glossed as the view that, qua expressions, avowals are not truth-evaluable. Contemporary neoexpressivists like Finkelstein and Bar-On have argued that avowals are expressions, and truth-evaluable besides . In contrast, this paper provides a defence of the view that avowals are, qua expressions, truth-evaluable. This defence is based on an argument (...) from disagreement, to the effect that an adequate explanation of the existence of disagreement involving both cases of avowals and cases of nonlinguistic expression (like winces) supports a view according to which genuine (sincere, truthful) expression is what truth amounts to in avowals.

This paper claims that we have direct and complete perceptual access to other people’s emotions in their bodily and behavioural expression. The claim is understood, not by analogy with the perception of three-dimensional objects or physical processes, but as a form of Gestalt perception. In addition, talk of direct perceptual access to others’ emotions is shown not to entail a behaviourist view of mind; and talk of complete perceptual access is shown to include both the phenomenological character and the dispositional (...) nature of emotions.

José Luis Bermúdez ha defendido una explicación no-circular de la autoconciencia en virtud de contenidos no-conceptuales de primera persona, explicativa y ontogenéticamente básicos. En este artículo se argumenta que los contenidos no-conceptuales explicativamente básicos caen en el mito de lo Dado; mientras que los contenidos no-conceptuales ontogenéticamente básicos, aunque lo evitan, no constituyen la mejor explicación de la adquisición de capacidades cognitivas.

A central feature in contemporary discussions of selfknowledge concerns the epistemic status of mental selfascriptions, such as “I have toothache” or “I believe that p”. The overall project of such discussions is to provide an account of the special status of mental self-ascriptions vis-à-vis other knowledge-claims, including ascriptions of mental states to others. In this respect, two approaches have gained currency in contemporary philosophy. Some authors have focused on the notion of expression, stressing that self-ascriptions are expressions of one’s mental (...) life; whereas others have singled out the notion of transparency as crucial, since self-knowledge involves self-beliefs, and the latter are transparent to one’s available evidence. This critical notice explores one instance of each approach, in order to assess their prospects of success. It concludes that both approaches fail to articulate an account that satisfactorily accommodates the first-person component in the notion of self-knowledge. (shrink)
