The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the primary (...) characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

Sus postulados constituyen un imprescindible legado para formar en los estudiantes universitarios valores éticos que los conviertan en mejores seres, humanos y profesionales. En su recorrido desde México hacia Guatemala, el Apóstol pretende resaltar la figura del negro de raza pura que allí vivía. Estas consideraciones se ofrecen a partir del texto Livingstone. El artículo tiene como objetivo develar algunas (...) ideas que permitan un desarrollo político-ideológico, ético y estético integral donde se destaque el conocimiento y respeto por la historia, la autoctonía de los pueblos americanos y la cultura patrias. ABSTRACT The work addresses a facet within Martian humanism that reflects its considerations in its struggle for the lands of America. Its postulates constitute an essential legacy to form in university students ethical values ​​that turn them into better beings, human beings and professionals. On his journey from Mexico to Guatemala, the Apostle pretends to highlight the figure of the black of pure race that lived there. These considerations are offered from the Livingstone text. The article aims to reveal some ideas that allow a political-ideological, ethical and integral aesthetic development where knowledge and respect for history, the autochthony of the American people and the patriotic culture are highlighted.

El resultado investigativo se centra en una de las prioridades de la línea del polo científico territorial y nacional: la necesidad de rescatar el papel de la intelectualidad cubana durante la República. Se analiza el papel de la cultura y la cubanía en la cosmovisión filosófica de Juan Marinello. El método empleado presupone un análisis dialéctico de la realidad, sustentado en una perspectiva crítica que permite interpretar y enriquecer la concepción sobre los hechos y procesos históricos. Desde una visión holística (...) del pensamiento filosófico cubano se revela la complejidad de un fenómeno multifactorial, la cubanía, como construcción cultural, a partir de la articulación de la concepción martiana y marxista de la cultura y los valores, lo que constituye un acierto del quehacer teórico - práctico marinelliano. El conocimiento de esta perspectiva enriquece los estudios sobre la obra de este intelectual y contribuye a dilucidar el devenir ideo-artístico y cultural cubano. The result of the research focuses on one of the priorities of the territorial and national scientific pole line: the need to recover the role of Cuban intellectuals during the Republic. The role of culture and Cubanism in Juan Marinello's philosophical world view is analyzed. The method used presupposes a dialectical analysis of reality, based on a critical perspective which allows to interpret and enrich the understanding of events and historical processes. From a holistic point of view of the Cuban philosophical thinking, Cubanism, a complex multifactorial phenomenon, is revealed as a cultural construction, starting from the articulation of Marti's and Marx's conception of culture and values, which is a good result of Marinello's theoretical-practical work. The knowledge of this perspective enriches the studies on the work of this intellectual and contributes to the clarification of the Cuban ideo-artistic and cultural evolution. (shrink)

Los métodos productivos de enseñanza preparan a los estudiantes para resolver problemas semejantes a los que se enfrentarán en el ejercicio laboral. Este trabajo tiene como objetivo fundamentar la pertinencia de la utilización del caso clínico como herramienta didáctica para la enseñanza en las ciencias básicas biomédicas, mediante un sistema de tareas para abordar los contenidos del tema Fisiología de la sangre de la asignatura Sangre y Sistema Inmune de la carrera de medicina. El caso clínico permite la vinculación de (...) las ciencias básicas biomédicas con las ciencias clínicas. Su utilización contribuye a la aproximación del estudiante de las ciencias básicas al estudio de estas durante su formación médica. El aprendizaje se logra a lo largo del proceso de resolución del mismo, se estimula la incorporación de conceptos necesarios para resolver el problema y se aprende un método para abordar situaciones en la práctica. Se elaboró un sistema de tareas y preguntas derivadas del problema profesional síndrome anémico. El problema docente se basó en un artículo médico que expone un caso de lesiones por empalamiento que produjo un gran sangramiento en un individuo. Se elaboraron preguntas problémicas relacionadas con la fisiología de la sangre y el tratamiento que recibió el paciente con eritropoyetina, factores de la coagulación y soluciones cristaloides en sustitución de la sangre. Se incluyó una pregunta que aborda un conflicto ético para sistematizar los conocimientos adquiridos en la asignatura Sociedad y Salud II. Productive teaching methods train students to solve problems similar to those they will face in their work life. The objective of the paper is to argue pertinence in the use of the clinical case as a didactic tool in biomedical basic sciences teaching by means of a task system that deals with the contents of the Blood Physiology subject in the Blood and Immune System subject matter of the medicine degree. Clinical cases enable the link between biomedical basic sciences and clinical sciences. Their use contributes to basic sciences students' approach to the study of the latter during their medical training. Learning is achieved through its solving process; the introduction of necessary problem-solving concepts is encouraged and a method to deal with in-practice situations is learned. A task and questions system derived from the anemic syndrome professional problem was made. The teaching problem was based on a medical article which presents a case of an individual who suffered impaling injuries which caused a great bleeding. Problem questions related to blood physiology and to the erythropoietin-based treatment the patient received, coagulation factors and crystalloid fluids used as blood substitutes, were prepared. It was included a question that deals with an ethical conflict in order to systematize the knowledge acquired in the Society and Health II subject matter. (shrink)

The notion that patients’ medical decision-making capacity depends on risk considerations has some acceptance in the bioethical literature. However, it arouses some criticism since it seems to give rise to paternalistic attitudes. In addition, the idea of capacity assessment as a collaborative space in which aid is given to the patient is emphasized so that they can decide about their life. It does not seem ethically acceptable to pose the evaluation as a simple observer report. Capacity assessment can sometimes be (...) impossible or inconsequential. In short, capacity assessment is a procedure that, used wisely, can allow the patient to take charge of their life. Misused, it can be the gateway to unjustified paternalistic actions. (shrink)

El fenómeno migratorio en Chile ha presentado patrones cambiantes durante los últimos años. Focalizado especialmente en la migración proveniente desde Venezuela, el presente artículo tiene por objetivo comprender el proceso de búsqueda y asentamiento residencial de mujeres venezolanas en Chile. Para ello se realizaron entrevistas cualitativas en Valparaíso y Viña del Mar, a través de las cuales se recabaron las principales dificultades que ellas deben atravesar para acceder a la vivienda, que se transforman en imbricados procesos de racialización y feminización. (...) Sin embargo, también se evidenció la existencia de múltiples estrategias de agenciamiento desplegadas para la obtención de un lugar donde vivir y cuidar de sus familias. Así, y desde un enfoque interseccional que comprende los estudios urbanos, raciales y de género, se concluye que, si bien las mujeres venezolanas migrantes deben enfrentarse a contextos de discriminación y segregación en la búsqueda de vivienda, también establecen mecanismos colaborativos que permiten su acceso, tales como el allegamiento, la cohabitación, la gestión compartida y la creación de redes.

Se presenta una reflexión acerca de la importancia de la labor docente ante los cambios curriculares y las demandas educativas contemporáneas. El profesor debe ser capaz de encaminar sus esfuerzos en el proceso de aprendizaje de sus estudiantes, tomando como base sus propias experiencias y movilizándolas hacia el desarrollo de la consciencia colectiva, que haga frente a los desafíos actuales. Palabras clave: educación, docencia, educación centrada en el estudiante, aprendizaje signfiicativo.

The purpose of the following investigation is to understand how children from the old historic district El Refugio (or Barrio del Refugio) of the city of Puebla (Mexico) live in public spaces and what their days and nights look like. It is extremely important to understand the reasons for their appropriation of various places in the city because it allows one to explore the conditions in which they manifest autonomous attitudes. This article is therefore not only about customs and culture, (...) but also about everyday relationships with the environment. Children are also involved in the activities of the group Re Genera Espacio (RGE) and the team of Benemérita Universidad Autónoma de Puebla (BUAP) in the development of all kinds of educational, artistic, and social activities. Among the most important results obtained is the observation that safety conditions are created by children in independent groups which move to other neighbourhoods (“barrios”), such as San Antonio and Santa Anita. Children make the street their space because they have important knowledge of the area. (shrink)

Since its origin, the city of Puebla has had representative elements in its public spaces that have survived for a long time, they are ornamental and utilitarian objects which are landmarks of the city. Street furniture is a benchmark of identity too. All elements have legends, they are references that have given identity to streets and avenues. Natural elements also refer to a city’s identity, like trees. But the natural element that defined origin, trace and growth of the city is (...) one of the least visible. In the sixties, the San Francisco River was piped, as a sign of the new modernity, and today it is a boulevard where thousands of cars pass. Thus, bridges and other types of elements that the population still remember, mainly the elderly, have been forgotten. In recent years, some initiatives have emerged to rescue the historical memory of daily life and the revaluation of repre­sentative objects of the city center, such as the Casa Analco Community Museum project, coordinated by the Faculty of Architecture of BUAP in collaboration with residents of the Analco neighborhood. This article discusses both the monuments, their relics, elements of nature that shape the city's identity, as well as the gradual loss of these symbols. (shrink)

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Background: Respecting dignity is having a profound effect on the clinical relationship and the care framework for terminally ill patients in palliative care units, hospices and their own homes, with particular consequences for the emergency department. However, dignity is a vague and multifaceted concept that is difficult to measure. Objective: The aim of this study is to define the attributes of dignity in end-of-life care in the emergency department, based on the opinions of physicians and nurses. Research design: A hermeneutic (...) phenomenological approach utilising Gadamer's philosophical underpinnings guided the study. Participants and research context: This research was conducted in Spain in 2013–2014. Participants included 10 physicians and 16 nurses with experience working in the emergency department. Two focus groups and 12 in-depth interviews were carried out. Ethical considerations: The study was approved by the Research Centre Ethical Committee (Andalusian Health Service, Spain). Findings: The results point to the person's inherent value, socio-environmental conditions and conscious actions/attitudes as attributes of dignity when caring for a dying patient in the emergency department. Discussion: Dying with dignity is a basic objective in end-of-life care and is an ambiguous but relevant concept for physicians and nurses. In line with our theoretical framework, our results highlight care environment, professional actions and socio-family context as attributes of dignity. Conclusion: Quality care in the emergency department includes paying attention to the dignity of people in the process of death. The dignity in the care of a dying person in the emergency department is defined by acknowledging the inherent value in each person, socio-environmental conditions and social and individual acceptance of death. Addressing these questions has significant repercussions for health professionals, especially nurses. (shrink)

Resumen: Este trabajo presenta un estudio empírico sobre la direccionalidad en la traducción de los adverbios de grado chinos. Se ha adoptado una metodología cuantitativa basada en corpus y se ha realizado un estudio cualitativo para analizar las diferencias entre las traducciones directas e inversas de los adverbios de grado en un corpus paralelo construido para este estudio. El resultado muestra que los traductores hispanos prefieren utilizar el método de equivalencia, mientras que los chinos tienden a usar el método de (...) omisión; asimismo, las traducciones inversas presentan un debilitamiento de grado mucho más relevante que las directas. De acuerdo con los hallazgos, se ha establecido que la subjetividad del traductor y las características de los adverbios de grado chinos, como el límite difuso entre las categorías y la degeneración semántica, son los principales factores de divergencias entre las traducciones directas e inversas. Este trabajo completa los estudios sobre la direccionalidad traductológica y la traducción de los adverbios de grado. Abstract: This paper presents an empirical study of the directionality of the translation of Chinese adverbs of degree. We adopt the corpus-based quantitative methodology and the qualitative method to analyze the differences between direct and inverse translations of adverbs of degree in a self-built parallel corpus. The result shows that the Spanish translators prefer to use the equivalence method, while the Chinese tend to use the omission method. Moreover, the inverse translations present a much more prominent weakening of the degree than the direct ones. We find that the subjectivity of the translator and the characteristics of Chinese adverbs of degree, such as the blurred border between different degrees and semantic degeneracy, are the main factors of the discrepancy between direct and inverse translations. This work complements the studies on translation directionality and the translation of adverbs of degree. (shrink)

The city of Puebla was put on the UNESCO list of Cultural Heritage of Humanity in 1987; its history dates back to the sixteenth century allowing for the preservation of various important buildings, such as churches with baroque and neoclassical facades, buildings from the period known as Novo Hispanics, when some of its historic neighbourhoods were founded, including the Barrio el Refugio, hereinafter referred to as BR, where indigenous people employed in the lime manufacture used to live. Since those times, (...) however, the neighbourhood has become a place with bad reputation, “a den of thieves”. The traditional, religious commemoration, the “Fiesta Patronal de la Virgen del Refugio,” is the most important celebration in the neighbourhood. In the Church of La Virgen del Refugio, built in the seventeenth century after an inhabitant painted a mural with the image of the virgin, the “mañanitas” are sung with the Mariachi. During the patronal feast, the “El Refugio Cultural Festival” is held with more than a hundred artists taking part and creating about a thousand murals according to the organiser’s estimation. This happens in the city where a project “Puebla Ciudad Mural” was started, as an initiative of the “Colectivo Tomate,” which sought to regenerate the neighbourhood through art, in alliance with the government and private companies. However, these policies are more tourist oriented rather than benefit the neighbourhood. For this reason, the graffiti movement “Festival Cultural el Refugio” is becoming a meeting point for urban artists from Mexico and Puebla, accustomed to taking up public or private space, as they demand space where they can live and express themselves. For ten years the festival has realised more than one thousand pieces of urban art, including Wild Style graffiti, bombs, stickers, stencil, and murals. All this is done under the patronage of the artists themselves, as three hundred of them come from all over the country to take part in every edition of the festival that does not receive any government support or other form of sponsorship.

IntroductionRheumatologists are the primary healthcare professionals responsible for patients with rheumatic diseases and should acquire medical ethical competencies, such as the informed consent process (ICP). The objective clinical structured examination is a valuable tool for assessing clinical competencies. We report the performance of 90 rheumatologist trainees participating in a station designed to evaluate the ICP during the 2018 and 2019 national accreditations.MethodsThe station was validated and represented a medical encounter in which the rheumatologist informed a patient with systemic lupus erythematosus (...) with clinically active nephritis about renal biopsy. A trained patient–actor and an evaluator were instructed to assess ICP skills (with a focus on kidney biopsy benefits, how the biopsy is done and potential complications) in obtaining formal informed consent, delivering bad news and overall communication with patients. The evaluator used a tailored checklist and form.ResultsCandidate performance varied with ICP content and was superior for potential benefit information (achieved by 98.9% of the candidates) but significantly reduced for potential complications (37.8%) and biopsy description (42.2%). Only 17.8% of the candidates mentioned the legal perspective of ICP. Death (as a potential complication) was omitted by the majority of the candidates (93.3%); after the patient–actor challenged candidates, only 57.1% of them gave a clear and positive answer. Evaluators frequently rated candidate communications skills as superior (≥80%), but ≥1 negative aspect was identified in 69% of the candidates.ConclusionsEthical competencies are mandatory for professional rheumatologists. It seems necessary to include an ethics competency framework in the curriculum throughout the rheumatology residency. (shrink)

Objectives To develop and test two educational programmes (interactive and passive) aimed at improving family doctors' (FD) prescribing practices and patient's knowledge and use of non-opioid analgesics (NOA).Methods The educational programmes were conducted in two family medicine clinics by using a three-stage approach: baseline evaluation, design, and implementation of educational activities, and post-programme evaluation. An interactive educational programme (IEP) was compared with a passive educational programme (PEP); both were participated by FDs and patients. The IEP for FDs comprised of workshops, (...) discussion groups, in-service training and guidelines, while for patients the IEP consisted of an interactive session with a video, leaflets and a discussion. The PEP consisted in delivering the guidelines to the FDs and the leaflets to patients. The effect of the programmes on the FDs was measured through the appropriateness of prescriptions and analysed using the differences-in-differences estimator (D-in-D), and on patients through changes in self-medication and in their knowledge about the proper use and adverse events by analysing the inter- and intra-group differences before and after the programmes.Results The IEP obtained better results to improve appropriate FDs prescription of NOA than PEP (D-in-D = 15%). Regarding the patients, the PEP group reached higher reduction of self-medication than the IEP group (13.4% vs. 9.1%); the knowledge of proper NOA use increased by 8.5% in both groups, whereas knowledge of NOA-related adverse events was better in the IEP (39.6%) than in the PEP group (9.2%).Conclusions The IEP was better to improve the doctors' abilities to prescribe NOAs, and both programmes improved patients' knowledge.

The current times call for reforms in educational processes. The Covid-19 pandemic had an unforeseen impact on the educational system in all countries. This need for change requires new pedagogies and new methods for teaching and learning. Understanding the need for change is essential for the formulation of adaptive proposals, as well as for the generation of training activities to complement the teaching curriculum. New educational practices lead to a vision of educational quality, with new approaches that allow the continuous (...) integration of knowledge and permanent interaction with the student. This paper presents an analysis of the new teaching methodologies in times of confinement due to the pandemic caused by Covid-19.

The percentage of female entrepreneurs is far below the level of males, although it has increased over the past several years. Based on the theory of planned behavior, the purpose of this article is to specify a model in which the relationship among entrepreneurial potential, gender and entrepreneurial intention are explored, by analyzing how perceived behavioral control (PBC) and perceived entrepreneurial skills, as exogenous variables, affect expression of intention for business, and how these are mediated by their entrepreneurial motivations and (...) risk taking propensity. Control variables where also included in this model, such as necessity-driven motives for business, in order to observe whether these are an influential factor. An implementation of Structural Equation Modeling (SEM) was used to analyze data collected from 677 students. Variables within the model were compared by gender using t-Test, and all multivariate analysis were done by each one separately as well in order to better gauge their perceptions. Results showed that mean differences between males and females are not abundant, and come only from intentions, PBC and subjective norm, which are higher in males; and motives for business higher in females. Multivariate analysis shows gender differences at the mediation level and that necessity-driven motives are an influencing factor, more so in males, and it hampers the significance of subjective norm. Finally, the theoretical and practical implications of the results within the framework of entrepreneurship in Spain and future alternatives to improve the entrepreneurial potential are discussed.

This paper examines and analyzes five definitions of ‘existential risk.’ It tentatively adopts a pluralistic approach according to which the definition that scholars employ should depend upon the particular context of use. More specifically, the notion that existential risks are ‘risks of human extinction or civilizational collapse’ is best when communicating with the public, whereas equating existential risks with a ‘significant loss of expected value’ may be the most effective definition for establishing existential risk studies as a legitimate field of (...) scientific and philosophical inquiry. In making these arguments, the present paper hopes to provide a modicum of clarity to foundational issues relating to the central concept of arguably the most important discussion of our times.

No two individuals with the autism diagnosis are ever the same—yet many practitioners and parents can recognize signs of ASD very rapidly with the naked eye. What, then, is this phenotype of autism that shows itself across such distinct clinical presentations and heterogeneous developments? The “signs” seem notoriously slippery and resistant to the behavioral threshold categories that make up current assessment tools. Part of the problem is that cognitive and behavioral “abilities” typically are theorized as high-level disembodied and modular functions—that (...) are assessed discretely (impaired, normal, enhanced) to define a spectral syndrome. Even as biology reminds us that organic developing bodies are not made up of independent switches, we remain often seduced by the simplicity of mechanistic and cognitive models. Developmental disorders such as autism have accordingly been theorized as due to different modular dysfunctions—typically of cortical origin, i.e., failures of “theory of mind” (Baron-Cohen et al., 1985), of the “mirror neuron system” (Ramachandran and Oberman, 2006), of “weak central coherence” (Happe and Frith, 2006) or of the balance of “empathizing” and “systemizing” (Baron-Cohen, 2009), just to list a few. -/- The broad array of autonomic (Ming et al., 2005; Cheshire, 2012) and sensorimotor (Damasio and Maurer, 1978; Maurer and Damasio, 1982; Donnellan and Leary, 1995; Leary and Hill, 1996; Donnellan and Leary, 2012; Donnellan et al., 2012) differences experienced and reported by people with autism have by such theories typically been sidelined as “co-morbidities,” possibly sharing genetic causes, but rendered as incidental and decisively behaviorally irrelevant symptoms—surely disconnected from cognition. But what if the development of cortically based mental processes and autonomous control relies on the complexities and proper function of the peripheral nervous systems? Through such an “embodied” lens the heterogeneous symptoms of autism invites new interpretations. We propose here that many behavioral-level findings can be re-defined as downstream effects of how developing nervous systems attempt to cope and adapt to the challenges of having various noisy, unpredictable, and unreliable peripheral inputs.

This paper offers a renewed construction grammar analysis of linguistic constructions in a diachronic perspective. The present theory, termedAgentive Cognitive Construction Grammar(AgCCxG), is informed byactive inference(AIF), a process theory for the comprehension of intelligent agency. AgCCxG defends the idea that language bear traces of non-linguistic, bodily-acquired information that reflects sémiotico-biological processes of energy exchange and conservation. One of the major claims of the paper is that embodied cognition has evolved to facilitate ontogenic mental alignment among humans. This is demonstrated by (...) the results of a corpus study in which the patterns of association between verbs, the particle UP and argument structure in Old and Middle English have been studied. The conclusion is that, similar to biological systems, the linguistic sign system displays patterns of equilibrium and non-equilibrium. In other words, while in Old English usage near equilibrium was reached through the use of a conservative set of constructional semiotic templates (attachment patterns), associated with motor modalities, Middle English displays high rates of randomness resulting in a less stable, yet distinct, system of constructional attachment.

Universities increasingly play an important role in entrepreneurship, which has contributed to gender equality in the business world. The aim of this study is to establish a causal model of entrepreneurial intentions and explore it by gender, based on the dimensions of the Theory of Planned Behavior, and how these are mediated by the individuals’ resilience and psychological well-being. The previous work experience was considered as one of the control variables, in order to analyze whether this influence the entrepreneurial intention. (...) With a convenience sample of 644 Portuguese students, Structural Equation Modeling was used. For a better understanding, multivariate analyses were performed and each one was individually reported, and for appropriate comparisons by gender, the t-student test was used. The comparison of means, between genders, showed that there are differences only between perceived behavioral control, subjective norm, and entrepreneurial intention, with women scoring the highest values, and psychological well-being, with men scoring the higher. A serial mediation path was performed, and psychological resilience was found to mediate a significant effect between perceived behavioral control and intention in females, but not in males. It also mediates a significant effect between attitude and intention in females, but not in males. These results show that attitude is a determining factor for females to become entrepreneurs. Finally, after discussing the results, theoretical and practical contributions are analyzed, with regard to the field of entrepreneurship in Portugal, and alternatives are pointed out for a more entrepreneurial future, reinforcing the role of higher education institutions.

The purpose of this essay is to tackle the concerns brought up by Schopenhauer in his aesthetics and demonstrate a necessary relationship between human activity and the work of art, as well as how the latter might reframe and "rescue" man from his suffering condition, at least for some time. In this regard, we will start with his examination of the concept of the Idea, which was inspired by Plato's mold as a depiction of the Essence – or the Will (...) -, and how the knowledge through art is the only way to attain it. From now on, poetry, particularly in tragic forms, represents the greatest degree of knowledge, being capable of lifting man to the "Idea of humanity," as he refers to it, for reflecting more clearly the impetus of the Will, the foundation of the world. In this way, we will explore the tragic poem of T.S Eliot, The Hollow Men, through a Schopenhauerian lens to determine how he achieves the concept of humanity, in a symbiotic relationship between ethics and aesthetics, philosophy and poetry; the knowledge of mankind to take care of the self.

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.

La gestación por sustitución, llamada también subrogación de útero o alquiler de vientres, es una práctica que suscita múltiples problemas éticos relacionados con los límites morales del mercado, la idea del cuerpo humano como objeto de contrato o los conflictos entre libertad negativa y positiva. Además, la repercusión de las ideologías políticas y del feminismo en el debate es notable: por un lado, las izquierdas critican la mercantilización de la capacidad reproductiva, pues genera injusticias y grandes desigualdades; por otro, el (...) feminismo se opone a que las mujeres sean tratadas como medios para cumplir fines, y considera que la subrogación de útero conduce a la negación de las libertades conquistadas. El autor de este libro denuncia que el mercado reproductivo de corte neoliberal, nutriéndose del deseo de tener hijos y escudándose en la defensa de la libre elección, fomenta prácticas que perjudican a las mujeres gestantes, en clara desventaja económica y social, para satisfacer los intereses procreativos de las clases privilegiadas. Y en su crítica rescata conceptos clave de la izquierda emancipadora para abordar el debate en términos de derechos básicos y justicia social. (shrink)

En el contexto de los riesgos generados por la creciente aplicación de las neurotecnologías en el cerebro humano, se destaca la aparición de un nuevo derecho conocido como la libertad cognitiva, que se constituye como la libertad de las personas a tomar sus propias decisiones sin la interferencia de las neurotecnologías en su cerebro. El surgir de este nuevo derecho ha traído consigo profundas reflexiones éticas y jurídicas. En ese marco, desde un enfoque de derechos humanos, existen diversos argumentos que (...) reconocen, o no, la factibilidad de reconocer a este nuevo derecho en la categoría de un derecho humano y/o fundamental.
