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

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

El objetivo del trabajo es debatir los argumentos de la obra de Liat Levanon (2022), Evidence, respect, and truth. La primera parte presenta estos argumentos con un grado considerable de detalle; en la segunda, se hace un balance de su contribución a la teoría general de la prueba jurídica actual. En el balance se identifican sus aspectos positivos y negativos. Entre los primeros destaca que tener en cuenta el modelo de Levanon permite trazar mejor la distinción entre concepciones (subjetivistas y (...) racionalistas) de la prueba y entre versiones (no-doxásticas y doxásticas) del racionalismo probatorio; por lo tanto, también permite señalar los principales problemas de cada una y algunas sugerencias de solución. Su principal desventaja es que termina diluyendo la importancia de haber argumentado que el respeto a las partes requiere del mejor esfuerzo por eliminar el error. (shrink)

The first European settlements in the new world faced technical issues with the help of the XVI century scientific advances. Besides briefly exposing the scientific and technological situation, this paper explores, with the help of reverse engineering, two singular mechanical wits representative of the technological advances introduced in America to overcome different problems. Firstly, a pump, based on an alternative movement system through crankshafts and pistons used against the continuous flooding suffered in the Ciudad de México valley. Although flooding remained (...) a problem (it was solved in the XX century), hydraulic pumps were essential for continuous soil drainage. Secondly, a port crane for handling cannons, military devices, and construction materials during the Lima fortification in the XVII century. For both cases, reverse engineering, through engineering methods, Computer-Aided Design CAD programs, and additive manufacturing, provides virtual and/or tangible mockups that help to analyze and improve our knowledge about the dimensions, materials, and functions of used (and currently lost) mechanical systems during the American colonization.

This study examines the way that consent is reported for participation in school-based research involving children or young people aged from 5 to 16 years. Databases containing descriptions of research identified during systematic reviews were surveyed to determine to what extent consent is sought, and from whom, and to see whether reporting varied by study characteristics such as the age of participants, the country in which the research was carried out, research design and substantive area of study. Of a total (...) of 489 studies in school settings involving children or young people, less than a third (n=145:30%) reported seeking consent. Only one in seven (n=66:13%) sought consent from children or young people themselves. Consent was reported significantly more frequently in studies sourced from health promotion reviews, when compared to those sourced from education reviews. Codes of practice indicate that researchers should seek consent from research participants. This study demonstrates that these principles are often not reflected in practice. (shrink)

Resumen:Por un lado, el trabajo pretende mostrar de qué modo el “tono” de Arendt en sus trabajos académicos, tal y como lo señalara Scholem en una de sus misivas críticas a la autora, lejos de ser frívolo o burlón (como se apuntaba en esa crítica) produce una brecha perturbadora, por la cual los lectores y las lectoras de Hannah Arendt pueden desvelar hipocresías y actuar con una nueva responsabilidad. Por otro lado, el artículo señala diversos conceptos filosóficos, algunos ya sometidos (...) a investigación por Arendt, que en sí mismos presentan la fuerza de crear un mundo y unos seres humanos, con la energía teórica y real necesaria como para transformarlos: “pensar”, “actuar”, “amar”, son algunos de ellos. En este último sendero, utilizaremos la ayuda de sus discípulas, Fina Birulés y Marina Garcés.Palabras clave: Hannah Arendt; Tono; Filosofía moral; Responsabilidad; Compasión; Historia. (shrink)

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.

The endocannabinoid system is the target of the main psychoactive component of the plant Cannabis sativa, the Δ9‐tetrahydrocannabinol (THC). This system is composed by the cannabinoid receptors, the endogenous ligands, and the enzymes involved in their metabolic processes, which works both centrally and peripherally to regulate a plethora of physiological functions. This review aims at explaining how the site‐specific actions of the endocannabinoid system impact on memory and feeding behavior through the cannabinoid receptors 1 (CB1R). Centrally, CB1R is widely distributed (...) in many brain regions, different cell types (e.g. neuronal or glial cells) and intracellular compartments (e.g. mitochondria). Interestingly, cellular and molecular effects are differentially mediated by CB1R according to their cell‐type localization (e.g. glutamatergic or GABAergic neurons). Thus, understanding the cellular and subcellular function of CB1R will provide new insights and aid the design of new compounds in cannabinoid‐based medicine.Also watch the Video Abstract. (shrink)

Abstract“The Book of Secrets in the Results of Ideas”, usually called “The Book of Secrets” is a codex containing drawings and descriptions of thirty-one artifacts attributed to the engineer Alī Ibn Khalaf al-Murādī, who lived in Andalusia in southern Spain at the beginning of the 11th century. This manuscript is one of the first written testimonies that describe medieval mechanisms with complex precision. The aim of this work is to reconstruct and study from a historical and technological point of view (...) two of the ancient artifacts contained in the “Book of Secrets”, the “Fortress Demolisher” and the “Magic Well”. The “Fortress Demolisher” is a war machine designed to demolish the upper part of the walls or towers and consists of a battering ram mounted on a platform that can be raised several meters above the ground using a scissor mechanism. The “Magic Well” is a mechanism with several pulleys whose purpose is to raise water several meters from the bottom of a well by collecting a small portion of rope. To reconstruct the two artifacts, a digital model and a detailed study of the geometry and operation of the mechanisms, were first carried out. 3D printing, using the Fused Deposition Modelling technology, made the physical reproduction. The digitization and physical reproduction by 3D printing of the mechanisms represent an update of the traditional ways of transmitting knowledge. The use of these new technologies makes the knowledge more accessible, understandable and attractive. (shrink)

Este artículo defiende la relevancia de la filosofía en el estudio contemporáneo de conceptos. Con el desarrollo de la ciencia cognitiva, la teorización naturalista e interdisciplinaria acerca de los conceptos ha cobrado impulso. En este contexto, se ha argumentado recientemente que las teorías filosóficas de conceptos no son acerca del tipo de cosas que interesan a los psicólogos, descartando así la pertinencia científica de la contribución filosófica mencionada. Presentamos y discutimos dos casos que sugieren lo contrario, como un intento de (...) reivindicar el papel crucial que tiene la filosofía en el desarrollo de teorías empíricas de conceptos.

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

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

La sociedad del conocimiento y la introducción en los procesos de enseñanza-aprendizaje de las tecnologías de la información y la comunicación, están exigiendo de quienes nos dedicamos a la educación en el ámbito universitario, la utilización de nuevas estrategias didácticas y la reinvención de algunas antiguas o no tan nuevas. Se trata de dar respuesta a la demanda social de “aprender de otra manera” para mejorar la inserción de los nuevos egresados en su ámbito profesional. Esta nueva forma de aprender (...) debe tener en consideración las exigencias de los nuevos contextos de enseñanza-aprendizaje, donde el protagonismo de los estudiantes es un elemento esencial y la relación de lo aprendido con sus posibilidades de aplicación en el contexto profesional es el otro. Casualmente el modelo de formación basado en competencias desde el enfoque socioformativo coincide en ambos protagonismos y el portafolio como estrategia didáctica que puede utilizarse en este modelo puede ayudar a dotar de protagonismo al que aprende haciéndole tomar conciencia de que el aprendizaje no se produce de manera automática sino a través de una serie de pasos y etapas que a la vez que se van consiguiendo nos permiten reflexionar el proceso. Una vez llevado a cabo este proceso de reflexión general, puede aplicarse en el ámbito médico para iniciar al estudiante a tomar conciencia de su semejanza con el diagnóstico clínico.

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

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

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

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

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

Objective: To present a narrative review of the history of bioethics in Latin America and of scientific output in this interdisciplinary field. Methods: This was a mixed-methods study. Results: A total of 1458 records were retrieved, of which 1167 met the inclusion criteria. According to the Web of Science classification, the predominant topics of study were medical ethics, social sciences and medicine, and environmental and public health topics. Four themes of bioethics output in the Latin American literature have emerged: issues (...) involving the beginning and end of life, ethics in human research, patient–provider relationships, and ethics training for health professionals. Conclusion: Although bioethics is a growing interdisciplinary field in Latin America, its academic impact is still very low, and programmes are highly concentrated in large urban centres in a few countries. Challenges includes the regional and international impact of local scientific output. (shrink)
