Trait emotional intelligence concerns our perceptions of our emotional abilities, that is, how good we believe we are in terms of understanding, regulating, and expressing emotions in order to adapt to our environment and maintain well-being. In this article, we present succinct summaries of selected findings from research on the location of trait EI in personality factor space, the biological underpinnings of the construct, indicative applications in the areas of clinical, health, social, educational, organizational, and developmental psychology, and trait EI (...) training. Findings to date suggest that individual differences in trait EI are a consistent predictor of human behavior across the life span. (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.

This paper consists of a series of reflections of external sensitive knowledge: what does it mean to know a color, a sound, etc. Three different views are compared Zubiri, Leonardo Polo and Aquinas.

En este trabajo se define formamente el concepto de representacion en química utilizando homomorfismos desde estructuras algebraicas, que llamamos sistemas de tipo C, en otras estructuras especiales de símbolos muy relacionados con los que son habituales en la qímica experimental. Para la definicion de los sistemas de tipo C se ha seleccionado un conjunto minimo de relaciones y funciones, que son necesarias para expresar proposiciones significativas en química. Tambien se define un lenguaje formal de primer orden adecuado a los sistemas (...) de tipo C, que llamamos L. EI resultado principal que se demuestra es que toda representación que verifica las mismas sentencias de L que un sistema de tipo C, es necesariamente isomorfo a él. Se concluye por lo tanto que puede existir un problema linguístico subyacente en la aplicacion que de la mecaníca cuántica se hace en la química teórica.The concept of representation in chemistry bas been formallv defined by means of homomorphisms from algebraical structures, which we call type-C systems, to some special sets of symbols which can be related to the symbols ordinarily used in experimental chemistry. A minimum number of relations and functions, which would suffice to express significant propositions in chemistry, have been chosen to define type-C systems. A first order formal language L adequate to type-C systems has been defined. It has been shown that each representation that verifies the same sentences of L as a type-C system is necessarily isomorphic to it. It is concluded that a systematic study of the representation problem in chemistry is in order because a deep language problem underlies the application of quantum mechanies to chemical problems.

La primera propuesta ética de corte aristotélico unía la racionalidad práctica con la búsqueda de un bien supremo que constituye la felicidad del hombre, realidades éticas fundamentales que iluminan la experiencia moral más básica. La racionalidad ética moderna, por un influjo neoestoico, ha volcado una sospecha respecto de esta propuesta por considerarla inadecuada para responder a una ética universal con la dificultad añadida de determinar la felicidad del hombre, por lo que ha centrado toda la visión ética en la relación (...) ley-conciencia. La revisión de la perspectiva cristiana testimoniada por San Agustín, San Máximo el Confesor y Santo Tomás de Aquino responde a estas preguntas por la emergencia de la referencia cristológica como universal concreto de la experiencia cristiana manifestado en el Amor de Cristo.

Solo el atrevimiento característico de la sabiduría nos impulsa a tomar el camino más complejo de pensar en el amor, pues nos hace conscientes del error de querer construir lo principal de la existencia en un sentimiento blando como la arena, incapaz de resistir cualquier contradicción de importancia.

Es una elección trascendental que, como el Papa Benedicto XVI ha señalado con fuerza, tiene una repercusión social de máximo relieve. (shrink)

As opposed to Descartes, and in accordance with authors such as Nietzsche, Darwin or Chomsky, Pinker sustains that language is just another instinct of human nature. But he differs himself from Chomsky by affirming that language is also the result of the mechanism of natural selection. Recent discoveries seem to strengthen Pinker’s thesis, in as far as it has been possible to establish a link between the FOXP2 gene and language. Philosophy should take good note of these results, as they (...) fully affect the status of lógos: from now on, it is possible, without needing to resort to any type of transcendence, to consider language as constitutive of human singularity regarding other species and, at the same times, as just another avatar in the evolution of the natural world.

Este artículo estudia, desde un punto de vista analítico, la teoría de la percepción que AndrésBello presenta en su Filosofía del Entendimiento. El objetivo central consiste en elucidar cuáles sonlos elementos que componen y estructuran el proceso de la percepción. En este sentido, se procedemediante el análisis de los capítulos y los apéndices relacionados con los temas de la percepción, quecorresponden con la primera parte denominada, “Psicolojía mental”. De conformidad con lo anterior,se analizan las nociones de alma o espíritu, conciencia, (...) sensación, intuición, referencia o juicio, eimpresión. Metodológicamente, se recurre a las estrategias y recursos que para el trabajo filosóficoprovee el análisis del lenguaje. Finalmente, se concluye que la teoría de la percepción en Andrés Bello,involucra la colaboración de una serie de subprocesos como la intuición, la sensación y la referencia ojuicio, además de reclamar como indispensable la unidad e indivisibilidad del alma o el “yo”.

El presente ensayo plantea la posibilidad de considerar nuevamente al diseño editorial como una actividad artística. Este campo no pudo escapar al fenómeno de la sociedad del espectáculo que hoy envuelve a casi toda actividad humana. Ello indiscutiblemente afecta la manera en que se valora esta actividad actualmente, vista las más de las veces como un simple aditamento utilitario con más fines comerciales que artísticos. A pesar de ello no deja de ser loable una revaloración de la disciplina que la (...) considere como una producción también transutilitaria, un fenómeno a la vez estético y extraestético y una actividad que, a través de su propia praxis, construye al ser histórico...

La reivindicación del sentimiento moral en el pensamiento materialista de M. Horkheimer adquiere nueva relevancia en el actual debate sobre los fundamentos y la motivación de la acción moral. Pero esa relevancia se malograría si fuera interpretada en un sentido contrario a su genuina intención. Ella no está, en efecto, en abrir la puerta a un irracionalismo romántico ni en proponer un retorno a una fundamentación premoderna, metafísica o teológica, de la moral, anticipándose a buena parte del actual pensamiento neoconservador. (...) Su originalidad y relevancia radican más bien en que el planteamiento materialista de Horkheimer incita a una decidida superación de las morales idealistas, formales y abstractamente universales, es decir particulares, hacia una moral postidealista de la compasión y la justicia universal.

This text considers the results of the western powers’ recognition of Kososvo’s independence from three perspectives: firstly, the possible consequences (of which what is happening in Georgia already gives us some proof) of this independence proclaimed and recognised outside the provisions of international law, and which can be considered a precedent in other territories with similar problems; secondly, it proposes, following Hegel, a rational conception of the state, far removed from ideas of ethnicity based on race, language, and so on, (...) in which nationalism finds its inspiration. Finally, it analyses and criticises from the Hegelian perspective, as updated by the reasoning of authors such as Habermas, the foundations of nationalism, especially its mistaken defence of the pre-eminence of collective over individual rights.

In this, paper we report some of the first news about the arrival of books and pamphlet to Cuba during the XVI and XVII centuries. The press was introduced at the beginning of the XVIII century, but its production was short until La Habana was taken by the English in 1762. Since its origins, the Spanish crown thought that everything in relation to the printing world should be under control. Therefore, this crown delayed the press implantation. decreed a lot of (...) restrictive laws and banned the arrival of a large number of printed works to the New World.

Среди выдающихся латиноамериканских философов, которые так или иначе занимаются аксиологическими nроблемами, находится месиканец Эдуардo Гарсия Майнез. По мнению Майнеза, каnитальные проблемы аксиологии могут быть сведены к четырем: а) проблема существования ценности; б) nроблема оценочного nознания; в) проблема реализации ценности; д) проблема свободы выбора личностью ценности. В данной работе анализируется в основном те идеи этого автора, которые касаются nервой из этих больших nроблем - вопроса о существовании ценностей. Entre los más destacados filósofos mexicanos que trabajan la problemática axiológica se encuentra el (...) mexicano Eduardo García Maynez. En opinión de Maynez los problemas capitales de la axiología son cuatro: a) el problema de la existencia del valor; b) el problema del conocimiento valorativo; c) el problema de la realización del valor; d) el problema de la libertad del hombre en la elección del valor. En este trabajo se analiza, en los fundamental, las ideas de este autor referidas al primero de estos grandes problemas: el tema de la existencia de los valores. (shrink)

The question of whether the entrepreneur is born or made, forces us to respond that the entrepreneurial culture clearly breaks with the myth that entrepreneurs are born. Currently, it is considered that entrepreneurial skills can be acquired like any other discipline and that is why it should be taught. Their teaching and learning are key to the well-being of the teacher and to the positive achievement of the students. The entrepreneurial culture is an educational objective of developed societies and has (...) its origin in the business culture. There are two current models, American and European. The one that develops in the Extremadura region, based on the European model, tries to create a vital state in the participating students that enhances competences such as creativity, personal initiative or self-confidence, elements that try to generate a true motivation to undertake. The motivated, accomplished and positive teacher contributes to that achievement and achieving it favors the well-being of teachers. It’s a round trip. It is a “do ut des.” In our research, we evaluated four entrepreneurial culture programs in the classroom: “Junioremprende,” “Teenemprende,” “Experemprende,” and “Youthemprende.” The teachers involved in the programs are 356, and the valid questionnaires are 154. The students enrolled in the programs are 4800, and the questionnaires valid 1198. In the questionnaire, one of the key questions is “general teacher satisfaction,” with 17 common questions for all the programs. An essential question posed is: “I am satisfied with the achievements obtained by my students to participate in the program” The results of our research, according to a seven-point Likert scale, gives a very high degree of teachers’ satisfaction. Their satisfaction was centered on the perception of their teachings are conducive to the achievement of his students. The degree of teacher satisfaction for each of the programs and significantly means differences were found with Junior program resulted the more satisfied for teachers. For students, participation in the programs resulted in high development of entrepreneurial competencies. Similarly to teachers results, Junior program was found more significant in developing students’ entrepreneurial competencies indicating that entrepreneurial education is very appropriate for children. Findings of this study suggest that entrepreneurial education should be encouraged for students at every stage of education. (shrink)

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

Smart grids are designed to revolutionize the energy sector by creating a smarter, more efficient and reliable power supply network. The rise of smart grids is a response to the need for a more comprehensive and sophisticated energy system that caters to the needs of homes and businesses. Key features of smart grids include the integration of renewable energy sources, decentralized generation and advanced distribution networks. At the heart of smart grids is a sophisticated metering system, consisting of intelligent electronic (...) devices that measure energy consumption and enable two-way communication between the utility company and the consumer. The information exchanged via these devices is critical, as it includes sensitive data such as energy consumption patterns and billing information. With the rise of the Internet of Things (IoT) and Industry 4.0, the security of this information is of utmost importance. This paper delves into the security challenges faced by advanced metering infrastructure (AMI) and highlights the crucial role played by cryptography in ensuring the secure exchange of sensitive information. Cryptographic protocols such as encryption, authentication and digital signatures are essential components of a secure smart grid infrastructure. These protocols work together to ensure the confidentiality, integrity and authenticity of the information exchanged between the utility company and the consumer. (shrink)

Nowadays, batteries play an important role in a lot of different applications like energy storage, electro-mobility, consumer electronic and so on. All the battery types have a common factor that is their complexity, independently of its nature. Usually, the batteries have an electrochemical nature. Several different test are accomplished to check the batteries performance, and commonly, it is predictable how they work depending of their technology. The present research describes the hybrid intelligent system created to accomplish fault detection over a (...) Lithium Iron Phosphate—LiFePO4 power cell type, commonly used in electro-mobility applications. The approach is based on the cell temperatures behaviour for voltage and current specific values. Taken into account the operating range of a real system based on a LiFePO4 cell, a large set of points of operation have been used to achieve the dataset. The different behaviour zones have been obtained by clustering as a first step. Then, different regression techniques have been used over each cluster. Polynomial regression, artificial neural networks and support vector regression were the combined techniques to develop the hybrid intelligent model proposed. The intelligent system gives very good results over the operating range, detecting all the faults tested during the validation. (shrink)

The linguafranca, or Mediterranean pidgin, was spoken by sailors and merchants that sailed the Mediterranean Sea during centuries. This pidgin borrowed terms from languages such as: Castilian and Catalan, French and Provencal (Occitanian language), Italian, Genovese, and Venetian. Moreover, words of Arabic and Neogreek origins were added to al1 this common mass. So, this lingua is a great interesting resource to deal with the study of the Spanish naval histoy in the Mediterranean Sea from 12" to 13" century, when its (...) usage started to vanish. From 16" century on, it started to be spoken in America. This common language, between Romance language nations, only uses the infinitive verb for al1 tenses and modes of verb's conjugation. Nowadays, there are terms that still remain in sailors' language such as wind names: leveche, jaloque, maestral or mistral, tramontana; meteorological phenomena names: bórea or boria; and nomenclature for typical crafts: paramola, escálamo, car, batallol, laud or llaüt, latino.

El presente artículo es el resultado de un proceso de investigación originado en la Maestría en Publicidad de la UTL, en la línea de Semiótica Publicitaria, dirigida por el profesor Vladimir Sánchez, quien en su seminario, ha venido construyendo un equipo de trabajo con los maestrantes en torno a la aplicabilidad de algunos de los postulados de la pragmática de Charles Sanders Peirce al campo publicitario. Los maestrantes Jairo Sojo y Juan José Arango, adelantaron algunas hipótesis sobre (...) el trabajo del profesor Sánchez, y, gracias a ello, se propuso a la UJTL y a la Universidad Santo Tomás, un proyecto interinstitucional de investigación titulado “Semiótica, planeación y estrategia publicitaria y de diseño. Proyecciones del Pragmatismo a la comunicación contemporánea”. En el marco de la investigación anteriormente mencionada, surge el artículo que aquí se presenta, como un primer planteamiento de las hipótesis de investigación que dan origen a dicho proceso y que pueden esbozarse en tres grandes aspectos. El primero, unas consideraciones generales sobre el pragmatismo desde una perspectiva publicitaria con énfais en la regla de cualificación planteada por Peirce en 1903. El segundo, la propuesta de un modelo de análisis de piezas publicitarias desde la operacionilización de la regla de cualificación. El tercero una modelación para la planeación de estrategias publicitarias a través de la regla de cualificación aplicada al cruce de los interpretantes ontológicos y los interpretantes modales.

La profesión de carpintero de ribera, sus técnicas, las herramientas utilizadas, los productos finales: los barcos, así como los conocimientos necesarios para su fabricación forman parte del patrimonio cultural marítimo universal. La construcción en madera es un oficio milenario que está en peligro de desaparición, y con ella uno de los elementos identitarios más importantes de las regiones costeras europeas. La escasa historiografía académica sobre los carpinteros de ribera como protagonistas es el principal motivo de este trabajo, que se adentra (...) en sus raíces, dando a conocer algunos de los aspectos más relevantes que definen e identifican la importancia del tema, como las principales actividades desarrolladas, su contextualización histórica, las técnicas, herramientas y la lengua franca marinera que compartían. Por ello, el fin último es proporcionar una fuente de referencia a quiénes apuesten, tanto de manera teórica como práctica, por la recuperación y la conservación de esta profesión ancestral sobre la que apenas existe información e investigación. Se concluye que la recuperación y gestión de este patrimonio, con vinculaciones amplias con otras actividades relacionadas, puede abrir perspectivas de consolidación patrimonial y económica en espacios marítimos poco desarrollados, ya que puede servir para sentar las bases de un futuro turismo cultural en el que estas técnicas sean protagonistas y sirvan para potenciar la identidad marítima en las regiones litorales.

This paper presents an overview of my work in philosophy from my first book on Friedrich Schiller and the political sublime to my most recent project on listening to traumatic forms of violence. Starting with a reflection on the autobiographical character of philosophy, I propose to take up the question of an aesthetic dimension of philosophical critique, where aesthetics is understood as an always already embodied perspective on the world, on truth, and on philosophical activity, as well as an always (...) already political realm, where the distribution of sense pre-determines our approach and articulation of experience. Departing from aesthetics understood and deployed as critique, the paper moves on to ask about the specific frameworks of sense or grammars that determine in advance the conditions of audibility in the realms of memory-building and history-making—particularly in those contexts where historical, political, and institutional forms of violence produce silencing and erasure. Putting in dialogue the latter with decolonial studies, I (re)interpret “traumatic violence” as a colonizing form of violence, understanding that one of its central aspects is that it is not only an assault on life but on the conditions of production of sense that make life legible as such. In this context, my project on grammars of listening seeks to carefully unpack these complex intersections while also explaining why I believe that a radical form of listening is an essential subversive/imaginative strategy against traumatic/colonial violence.

Behavioral interventions have shown promising neuroprotective effects, but the cascade of molecular, brain and behavioral changes involved in these benefits remains poorly understood. Projecte Moviment is a 12-week multi-domain, single-blind, proof-of-concept randomized controlled trial examining the cognitive effect and underlying mechanisms of an aerobic exercise, computerized cognitive training and a combined groups compared to a waitlist control group. Adherence was > 80% for 82/109 participants recruited. In this study we report intervention-related changes in plasma biomarkers and structural-MRI and how they (...) related to changes in physical activity and individual variables and their potential role as mediators in the cognitive changes. Our results show that although there were no significant changes in molecular biomarker concentrations in any intervention group, changes in ICAM-1 and SDF1-α were negatively associated with changes in physical activity outcomes in AE and COMB groups. Brain volume changes were found in the CCT showing a significant increase in precuneus volume. Sex moderated the brain volume change in the AE and COMB groups, suggesting that men may benefit more than women. Changes in molecular biomarkers and brain volumes did not significantly mediate the cognitive-related benefits found previously for any group. This study shows crucial initial molecular and brain volume changes related to lifestyle interventions at early stages and highlights the value of examining activity parameters, individual difference characteristics and using a multi-level analysis approach to address these questions.

Background: The field of voice and speech analysis has become increasingly popular over the last 10 years, and articles on its use in detecting neurodegenerative diseases have proliferated. Many studies have identified characteristic speech features that can be used to draw an accurate distinction between healthy aging among older people and those with mild cognitive impairment and Alzheimer's disease. Speech analysis has been singled out as a cost-effective and reliable method for detecting the presence of both conditions. In this research, (...) a systematic review was conducted to determine these features and their diagnostic accuracy.Methods: Peer-reviewed literature was located across multiple databases, involving studies that apply new procedures of automatic speech analysis to collect behavioral evidence of linguistic impairments along with their diagnostic accuracy on Alzheimer's disease and mild cognitive impairment. The risk of bias was assessed by using JBI and QUADAS-2 checklists.Results: Thirty-five papers met the inclusion criteria; of these, 11 were descriptive studies that either identified voice features or explored their cognitive correlates, and the rest were diagnostic studies. Overall, the studies were of good quality and presented solid evidence of the usefulness of this technique. The distinctive acoustic and rhythmic features found are gathered. Most studies record a diagnostic accuracy over 88% for Alzheimer's and 80% for mild cognitive impairment.Conclusion: Automatic speech analysis is a promising tool for diagnosing mild cognitive impairment and Alzheimer's disease. The reported features seem to be indicators of the cognitive changes in older people. The specific features and the cognitive changes involved could be the subject of further research. (shrink)

Impaired emotional capacity in antisocial populations is a well-known reality. Taking the dimensional approach to the study of emotion, emotions are perceived as a disposition to action; they emerge from arousal of the appetitive or aversive system, and result in subjective, behavioral, and physiological responses that are modulated by the dimensions of valence, arousal, and dominance. This study uses the International Affective Picture System (IAPS) to study the interaction between the type of picture presented (pleasant, neutral, or unpleasant) and group (...) (adolescents under custody in juvenile justice centers, adolescents under non-custodial measures, and secondary school students) in the emotional assessment of these dimensions. The interaction between the study variables was statistically significant. Statistically significant differences were found between the three types of pictures presented, in the ratings of unpleasant pictures between the custody group and the group of secondary students in regular schooling in valence, and in the ratings of unpleasant, neutral, and pleasant pictures in arousal, between the custody group and all groups. Discriminant analyses of each affective dimension indicate that the unpleasant pictures with violent and/or aggressive content tend to be in the functions that most differentiate the antisocial groups.
