This paper presents the design, simulation, and experimental verification of the fractional-order multiscroll Lü chaotic system. We base them on op-amp-based approximations of fractional-order integrators and saturated series of nonlinear functions. The integrators are first-order active realizations tuned to reduce the inaccuracy of the frequency response. By an exponential curve fitting, we got a convenient design equation for realizing fractional-order integrators of orders from 0.1 to 0.95. The results include simulations in SPICE of the mathematical description and the electronic implementation (...) and experimental measurements that confirm them. Monte Carlo and sensitivity tests revealed a robust realization. Contrary to its passive counterparts, the suggested realizations significantly reduce design and implementation efforts by favoring resistors and capacitors with commercial values and reducing hardware requirements.

Este trabajo parte del concepto de "instancia abridora de mundo" como uno de los conceptos más elaborados de la reflexión filosófica, desde el predominio del ente, pasando por la conciencia, hasta llegar a un modo singular de experiencia que encuentra su apoyo en la "finitud" y en la "desposesión". Los puntos esenciales del artículo son el análisis del frágil itinerario de la subjetividad, el estudio del Da-sein, como límite de la ontología substancialista, y la experiencia de la negatividad como forma (...) apropiada para alumbrar la manifestación del ser. En este sentido, se pone de relieve la contraposición existente entre ella y la experiencia del "tú", que se propone en Gadamer, y en la teoría de la acción comunicativa de J. Habermas. (shrink)

Kv10.1 is a voltage‐gated potassium channel relevant for tumor biology, but the underlying mechanism is still unclear. We propose that Kv10.1 plays a role coordinating primary cilium disassembly with cell cycle progression through localized changes of membrane potential at the ciliary base. Most non‐dividing cells display a primary cilium, an antenna‐like structure important for cell physiology. The cilium is disassembled when the cell divides, which requires an increase of Ca2+ concentration and a redistribution of phospholipids in its basal region, both (...) of which would be facilitated by local hyperpolarization. Cells lacking Kv10.1 show impaired ciliary disassembly and delayed entrance into mitosis. Kv10.1 is predominantly expressed during G2/M, a critical period for ciliary resorption, and localizes to the ciliary base and vesicles associated with the centrosome. This could explain the influence of Kv10.1 in cell proliferation, as well as phenotypic features of patients carrying gain of function mutations in the gene. (shrink)

El presente artículo se basa en una investigación llevada a cabo por profesores de la Universidad Pablo de Olavide de Sevilla, adscritos al Grupo de Investigación de Trabajo Social y Políticas Sociales (Plan Andaluz de Investigación, Desarrollo e Innovación -Ciencias Sociales, Económicas y Jurídicas (PAIDI, SEJ-452), a lo largo de dos años y dentro del marco de colaboración con la Fundación Mercasevilla. El objeto de dicha investigación ha sido el análisis de la sociabilidad de las personas mayores en el medio (...) urbano desde la sociabilidad a la dependencia. El estudio pone de manifiesto las diferencias existentes en el uso de los espacios según la edad de la población, los déficits que esos espacios muestran, y su relación con la situación de dependencia de las personas mayores. En relación a los datos obtenidos, se plantean conclusiones y orientaciones que pueden resultar de interés a técnicos, investigadores, planificadores del territorio y para aquellos que pueden decidir acerca de políticas que modifiquen el espacio urbano. El equipo de investigación establece una relación directa entre la integración social del colectivo de mayores, con el grado de participación en la sociedad en la que se encuentran, y por tanto, con el uso y acceso a los distintos espacios de sociabilidad, que es en definitiva donde ejercen esta participación social.

BackgroundMonitoring recovery–stress balance in sport is becoming more relevant to prevent training maladaptation and reach the optimal performance for each athlete. The use of questionnaires that identify the athlete’s recovery–stress state have much acceptance in sports due to reliability and useful, furthermore for its low cost. Identifying possible differences between sport modalities and sex is important to determine specific needs and possible intervention ways to keep a recovery–stress balance. The aim was to analyze the differences in the recovery–stress state and (...) mood states by sex and sport type during the competitive phase in young Mexican athletes. As a secondary objective, the psychometric properties of the Mexican version of the Recovery–Stress Questionnaire for Athletes were analyzed.MethodsA cross-sectional study was carried on with 461 athletes, 17.95 years old, from six sports disciplines. The RESTQ-Sport and Profile of Mood States were applied in a single moment. Differences by sex and sports modality were analyzed. RESTQ-Sport’s confirmatory factor analysis was performed after the stress and recovery theoretical structure of two stress and two recovery dimensions, and last, the concurrent validation with the POMS was carried on.ResultsSignificant differences by sex were found in the General Recovery and Sport Stress dimensions of the RESTQ-Sport as well as Vigor factor of the POMS, being higher for men; furthermore, both the Sport Recovery dimension of RESTQ-Sport and Cholera and the Fatigue and Depression factors from POMS also had differences by sport type, showing a less recovery and high stress for individual sport athletes. Goodness-of-fit indexes of the model for the RESTQ-Sport were acceptable. Pearson’s correlation between questionnaires was moderate.ConclusionThe recovery–stress state shows differences in the function of sex and sport modality. More special attention is suggested for women and individual sport athletes. The higher punctuation for men compared with women in sport stress dimension did not negatively affect the recovery–stress balance for male athletes. Finally, the Mexican context adaptation of the RESTQ-Sport provides a psychometric instrument suitable to assess the recovery–stress balance in Mexican athletes. (shrink)

El texto presenta los fundamentos filosóficos con los cuales configurar una filosofía latinoamericana que apuntale un proyecto de filosofía de la educación desde la educación popular. Esto se hace a partir del examen de la reflexión filosófica de Leopoldo Zea y Amado Osorio. Para ello, se desarrolla en torno a la presunta existencia de una filosofía latinoamericana, pensamiento filosófico latinoamericano, un presunto acuerdo sobre filosofía, una filosofía de la educación en América Latina y una filosofía de la educación como baluarte (...) de una educación filosófica en América Latina. El texto concluye, además, que una filosofía latinoamericana no tiene por qué tener como condición su ruptura con el pensar del hombre genérico; solo se trata de reconocer sus problemas vitales para aportar claridad reflexiva y actuar sobre ellos con respuestas, incluso, inspiradoras para otros pueblos.

Business ethics is one of the most significant demands made by institutional and individual investors, who usually require the participation of the board of directors in the planning and implementation of ethical behaviour in corporations. This is done by drawing up an ethics code and then monitoring its fulfilment. This study has a dual objective: first, to analyse the role played by the composition of the board of directors, and by that we mean its independence and the diversity of its (...) members, on the implementation and scope of an EC, and, second, to detect whether the corporate governance system moderates the level of involvement of the board in ethical issues. The findings obtained from a data panel sample made up of 760 listed companies from 12 countries for the years 2003–2009 show that the largest companies with large-sized and diverse boards implement the most developed ECs. Nevertheless, the extent of involvement of the independent directors is conditioned by the level of shareholder orientation characteristic of the system of CG in the corporation’s country of origin.

The present study aims to apply a program based on Hellison’s Teaching Personal and Social Responsibility Model (TPSR), traditionally used in Physical Education, to other educational subjects and examine the assessment of the teachers who carried it out during the 2018-2019 school year. The program was applied over eight months of one academic year and during at least 60% of the weekly class hours. Initially, 586 students participated, 429 being experimental subjects with 30 teachers, of whom 16 participated in the (...) interviews carried out, all of them being Secondary Education teachers. We used qualitative methodology through content analysis carried out with ATLAS.ti 7.1.3. The instruments used to collect information were semi-structured recorded group interviews. The conclusion is that the Personal and Social Responsibility Model can be applied to all subjects in the curriculum and is adaptable to any content and type of student body. As a basis for future research, we suggest the application of the model by all teachers involved in the same school year and the participation of students’ families. (shrink)

The relationship between social and financial performance (CSP – FP) has been a main objective in the literature on business management, as it would provide an economic justification for the social investment insofar as it contributes to the creation of value. This relationship has been empirically tested by several authors though without using a theoretical model that sustains this relationship. The aim of this article is to propose a theoretical model of the process of the creation of value from the (...) reputation generated by companies, integrating the factors that have been shown to be more relevant in this process from previous research, in such a way that hypotheses are put forward regarding the existence of this relationship and the factors that determine it. Finally, an empirical test is performed using the 100 most prestigious companies operating in Spain during 2004. (shrink)

A modo de preámbulo, consideramos importante mencionar que el presente ensayo pretende entrelazar los conceptos mirada y seducción desde distintas ópticas. Se plantean someramente algunas ideas desde la filosofía hasta el psicoanálisis. Se inicia con una “mirada” a las construcciones literarias de creadores de gran importancia, tales como Jean Braudrillard y Georges Bataille, en quienes se estudia la idea del ojo perverso, de la mirada y el deseo, subjetividad que nos atrapa. Se ambiciona articular con teorizaciones psicoanalíticas de lo inconsciente, (...) abundando en investigaciones freudianas y de otros teóricos del psicoanálisis para analizar e interpretar sus “seductoras” aportaciones.By way of preamble, we consider important to mention that this essay intends to link the concepts of look and seduction from different angles. Some ideas are raised from philosophy to psychoanalysis. The article starts with a “look” to the creators of literary constructions of great importance such as Jean Braudrillard and Georges Bataille, in order to study the idea of the evil eye, the gaze and desire, the subjectivity that catch us. The article aspires to articulate psychoanalytic theories of the unconscious, abounding in Freudian investigations and other theorists of psychoanalysis to analyze and interpret “seductive” contributions.

There is no consensus in the literature about the nature of terrorism. The authors’ main claim is that this is ultimately the result of the coexistence of two senses of the term, the action and the actor sense, which are not fully congruent. Rather than trying to advocate a specific conceptualization, the authors provide in this article a map of the different ways in which scholars talk about terrorism. They identify first the set of terrorist actions and the set of (...) terrorist actors. Terrorist tactics are a variety of the power to hurt, based on the lack of military power. Terrorist groups are underground ones with no territorial control. When the two criteria meet, the core of terrorism exists: coercive violence perpetrated by underground groups. The ambiguity that surrounds terrorism is caused by two other possibilities: actors with some measure of territorial control adopting coercive tactics and underground actors adopting military tactics. Although it is not possible to remove this ambiguity in empirical research, scholars can at least identify it and analyze it. The authors illustrate the two senses of terrorism and their interaction by using the most comprehensive dataset on terrorist incidents, the Global Terrorism Database. (shrink)

As a result of recent corporate scandals, several rules have focused on the role played by Boards of Directors on the planning and monitoring of corporate codes of ethics. In theory, outside directors are in a better position than insiders to protect and further the interests of all stakeholders because of their experience and their sense of moral and legal obligations. Female directors also tend to be more sensitive to ethics according to several past studies which explain this affirmation by (...) early gender socialization, the fact that women are thought to place a greater emphasis on harmonious relations and the fact that men and women use different ethical frameworks in their judgments. The goal of this paper is to determine the influence of these characteristics of the Board in terms of promoting and hindering the creation of a code of ethics. Our findings show that a greater number of female directors does not necessarily lead to more ethical companies. Moreover, within Europe as a continent, board ownership leads to an entrenchment of upper-level management, generating a divergence between the ethical interests of owners and managers. In light of this situation, the presence of independent directors is necessary to reduce such conflicts. (shrink)

This study adopts moral reasoning strategies to investigate why consumers support companies involved in ethical transgressions. Drawing on several cases of real multinationals publicly involved in tax avoidance practices, it aims to demonstrate that moral rationalization and moral decoupling depend not only on how consumers perceive the magnitude of the transgression, but also on their individual differences, such as political ideology and brand identification. A quantitative study with a sample of 3989 consumers of five different focal brands was employed to (...) test a set of hypotheses. Findings reveal that moral decoupling directly explains purchase intentions. However, rationalization only explains behavioral intentions if it leads to a reduction in the perceived immorality of the action. Furthermore, the study reveals significant differences across personal values. Left-leaning individuals tend to rationalize less and decouple more when they perceive that the magnitude of the transgression as egregious. Interestingly, consumers who are highly identified with the brand are less affected by the transgression and tend to be more supportive toward the brand by engaging in rationalization mechanisms.

This article examines the role of the Spanish Atomic Forum as the representative of the nuclear sector in the public arena during the golden years of the nuclear power industry from the 1960s to 1970s. It focuses on the public image concerns of the Spanish nuclear lobby and the subsequent information campaigns launched during the late 1970s to counteract demonstrations by the growing and heterogeneous anti-nuclear movement. The role of advocacy of nuclear energy by the Atomic Forum was similar to (...) that in other countries, but the situation in Spain had some distinguishing features. Anti-nuclear protest in Spain peaked in 1978 paralleling the debates of a new National Energy Plan in Congress, whose first draft had envisaged a massive nuclearization of the country. We show how the approval of the Plan in July 1979, with a significant reduction in the nuclear energy component, was influenced by the anti-nuclear protest movements in Spain. Despite the efforts of the Spanish Atomic Forum to counter its message, the anti-nuclear movement was strengthened by reactions to the Three Mile Island accident in March 1979. (shrink)

Hearing loss has been identified as a major modifiable risk factors for dementia. Adult candidates for cochlear implantation represent a population at risk of hearing loss-associated cognitive decline. This study investigated the effect of demographics, habits, and medical and psychological risk factors on cognition within such a cohort. Data from 34 consecutive adults with post-lingual deafness scheduled for CI were analyzed. Pure tone audiometry and Speech Discrimination Score were recorded. The Repeatable Battery for Assessment of Neuropsychological Status for Hearing impaired (...) individuals was used to measure cognition. Demographics, habits, and medical factors were evaluated. Depression was measured using the Hospital Anxiety and Depression Scale, and social inhibition with the Type D questionnaire. All participants suffered from severe to profound hearing loss. The mean RBANS-H total score was 83 ± 16. Participants reported a mean of years of formal education of 12 ± 5 years. The prevalence of habits and medical risk factors was: physical inactivity, body mass index >30, traumatic brain injury, hypertension, heavy alcohol consumption, smoking, and diabetes. Regarding psychological factors, the mean scores of social inhibition and depression were 10 ± 6 and 6 ± 5, respectively. The number of years of education was significantly correlated with the RBANS-H total score, and with the domains “Immediate memory”, “Visuospatial/constructional”, and “Attention”. The mean RBANS-H total score in participants who had university studies or higher level was 97 ± 9, with the remaining participants reporting a mean score of 75 ± 15. Men performed better in the “Visuospatial/constructional”. Physical inactivity was associated with lower scores in the “Delayed memory” ; hypertension correlated with lower RBANS-H total scores and “Attention”. Depression and social inhibition were negatively correlated with RBANS-H total score and with the “Immediate memory,” “Visuospatial/constructional,” and “Attention”. In adults with late-onset deafness scheduled to CI, educational level has a significant effect. Additionally, sex, physical inactivity, hypertension, and psychological traits of social inhibition and depression may also influence cognitive status. Long-term studies with more participants would enable us better understand the effects different risk factors on cognitive status. (shrink)

In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric (...) analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future. (shrink)

This article seeks to provide a reflection based on philosophy and sociology around the occupation, if any, of the humanities. According to the hermeneutics of founding texts on the question “What is man?” and on various perspectives on it, a reflection is configured that aims to sustain what, in the author's view, corresponds to be the basic and determining occupation of the humanities. For this, five sections will be developed in which an introduction to some basic ideas about the humanities, (...) foundations of a philosophical anthropology, what is man from the study of sociology, what is man from the study of biology and neurosciences, and the humanities as a whole are exposed. The article aims to contribute to the understanding that cultivating the humanities and developing them requires an intention to make them a conceptual and unfinished representation of the world, not a piece of ductile clay in the image and likeness of those who see in them the stage of praxis by excellence. It is mainly concluded that the relevance, the very nature of the humanities, lies in broadening the spectrum of questions about what is man, before attempting to provide complete answers, so that, at the very moment in which the crucial question “What is man?” is found a finished answer and it becomes law, not only is a resolved question left, but also a meaningless life.

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

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)

The assessment of learning in the ethical domain is one of the most complex aspects to attend in the educational context. In recent years, character education has contributed greatly to different social disciplines, such as education or nursing. However, the development of this approach has run up against several obstacles and limitations, as there is little evidence regarding its long-term effectiveness or its evaluation. This essay aims to identify some of the main difficulties to assess learning in the ethical domain, (...) as obstacles and possible constraints to Aristotelian-based character education. Methodology is analytical and of a philosophical-educational nature, based on which an argumentative analysis is constructed from the bibliographical review of the contributions of classical and contemporary authors. Results show the existence of four major problems and ten associated subproblems, both of an external nature linked to the contextual factors of assessment, and of an internal nature that affect the essence of the process itself, which highlight the difficulty of carrying out assessments of an ethical kind. Far from proposing a pessimistic position, we argue a realistic vision that allows educators at different educational levels to be aware of the limits and critical points of evaluation in the ethical domain.

ABSTRACT The objective of this study was to determine the accuracy of a brief informed consent quiz to detect consent comprehension in individuals with cognitive impairment and to explore the degree to which cognitive domains and recent substance use, independently, predict comprehension. We performed a secondary analysis of two cross-sectional studies in individuals with substance use disorders. The ICQ total score was used as the index test and the Montreal Cognitive Assessment as reference standard in receiver operating characteristic curves. Two (...) independent multiple binary logistic regression models were performed using cognitive domains and days of recent substance use as predictors of ICQ outcome. We analyzed data from 215 and 251 participants, respectively. The ICQ showed moderate accuracy for major cognitive impairment and lower accuracy for mild impairment. Optimal cutoff score was set at 10 points or less for detecting comprehension difficulty. Lower scores in Short-Term Memory, Attention, Language, and Orientation increased the probability of failing the ICQ. A procedure including both the ICQ and cognitive screening measure could improve the accuracy of consent comprehension assessments. (shrink)

We study whether the probabilistic postulate could be derived from basic principles. Through the analysis of the Strong Law of Large Numbers and its formulation in quantum mechanics, we show, contrary to the claim of the many-worlds interpretation defenders and the arguments of some other authors, the impossibility of obtaining the probabilistic postulate by means of the frequency analysis of an ensemble of infinite copies of a single system. It is shown, though, how the standard form of the probability as (...) the square of the scalar product follows from Gleason's theorem. (shrink)

More and more studies and research have found a positive relationship between the participation of young people in altruistic activities and helping others, but it is interesting to discover a relationship of that personal and vocational satisfaction in the preparation and training in a profession as important to society as teaching. For students who begin university studies related to teaching, their psychological well-being and motivation towards this activity are very relevant aspects to consider. The access to and attainment of a (...) University Degree with a great vocational character, such as that of Pre-School Teacher or Primary Education Teacher, can benefit the students who will be in charge. These future educational professionals will have adequate motivation and maintain a psychological well-being that, in short, will favour their personal balance and will impact their future students. This research aims to analyse the degree of psychological well-being and its relationship with the motivation towards starting the teaching career. A sample of 233 students and students aged between 17 or 19 years of age who are beginning university studies at the School of Education of Ciudad Real was selected. All participants are enrolled in the first year of the Degree in Pre-school and Primary Education. The relationship between the psychological well-being of the students and their motivation towards attaining a professional teaching career was analysed. Other variables such as age or sex were also taken into account. A quantitative study was carried out and the Ryff Psychological Welfare Scale and the Intrinsic Motivation Questionnaire (IMI) were used. Once the results were analysed, it was observed that there is a positive correlation between the perception of psychological well-being that the participants have and their motivation towards the beginning of university studies, whose professional focus is mainly direct teaching with the students of the early stages of Pre-school and Primary Education. There are also some significant differences, considering the age and sex of the participants. The vocational character of university preparation for the teaching profession may determine that students who begin their Degree studies have an important motivation towards the performance of their professional future.

Student performance and its evaluation remain a serious challenge for education systems. Frequently, the recording and processing of students’ scores in a specific curriculum have several flaws for various reasons. In this context, the absence of data from some of the student scores undermines the efficiency of any future analysis carried out in order to reach conclusions. When this is the case, missing data imputation algorithms are needed. These algorithms are capable of substituting, with a high level of accuracy, the (...) missing data for predicted values. This research presents the hybridization of an algorithm previously proposed by the authors called adaptive assignation algorithm, with a well-known technique called multivariate imputation by chained equations. The results show how the suggested methodology outperforms both algorithms. (shrink)

ABSTRACTThe social content of affective stimuli has been proposed as having an influence on cognitive processing and behaviour. This research was aimed, therefore, at studying whether automatic exogenous attention demanded by affective pictures was related to their social value. We hypothesised that affective social pictures would capture attention to a greater extent than non-social affective stimuli. For this purpose, we recorded event-related potentials in a sample of 24 participants engaged in a digit categorisation task. Distracters were affective pictures varying in (...) social content, in addition to affective valence and arousal, which appeared in the background during the task. Our data revealed that pictures depicting high social content captured greater automatic attention than other pictures, as reflected by the greater amplitude and shorter latency of anterior P2, and anterior and posterior N2 components of the ERPs. In addition, social content also provoked greater allocation of processing resour... (shrink)
