The traditional ludomotor activities (LA) are recognized by UNESCO as an intangible piece of cultural heritage. The ethnomotricity analyzes LA in its sociocultural context, taking into account the proprieties of rules or motor conditions (internal logic) and the link with local culture (external logic). The aim of this research was to identify and reveal the distinctive ethnomotor features of LA in order to understand the adaptations that occurred in the social scenario of the Spanish Civil War (1936–1939) in Lleida. The (...) corpus of the research was constituted by 101 LA which were collected from the analysis of 20 semi-structured interviews. An “ad hoc” tool was designed and agreed upon by expert observers. It was comprised of a total of 27 ethnomotor variables related to LA. The experts achieved high reliability [Cohen’s kappa coefficient (κ) and Spearman’s correlation coefficient = 1] when the classification of LA was carried out on two different occasions. Descriptive statistics, cross-tabulations (Pearson’s chi-squared) effect sizes, and two-step clusters were performed by external and internal logic variables. The presence or absence of motor interaction (X2= 9.029;df= 1;p< 0.003;ES= 0.298) was enlightening when comparing LA with and without a war connotation. On the other hand, the hierarchy of variables rested primarily on IL-Domain (Psycho-Coop-Oppo-Coop/Oppo) (PI = 1). Among other singularities, while two-step cluster analysis revealed a corresponding ethnomotor silhouette with cluster 1, with the warlike connotation (n= 48; 96.0%), its homologous structure was expressed (Cluster 2) in the absence of the warlike character (n= 26; 50%).

UNESCO in the 2030 agenda for sustainable development establishes respect for the environment and sustainability education as key elements for the challenges of society in the coming years. In the educational context, physical education can have a vital role in sustainability education, through Traditional Sporting Games. The aim of this research was to study from an ethnomotor perspective the different characteristics of two different groups of TSG in the Canary Islands, Spain. The corpus of this investigation was made up of (...) 513 TSG, identified by two analysis techniques and collected in a database. The categories corresponding to the variables of the internal logic of the game were the type of motor interaction, related to space, relationships with time, and relationships with objects. The study also examined the variables of external logic or sociocultural conditions such as the protagonists, playing areas, and game moments. The data analysis was carried out using descriptive and inferential statistics: cross-tables, effect sizes, classification trees, and the identification of frequency areas. Of the total number of playful activities identified, most were physical activities. These activities were Quasi-games without rules and TSG as well as activities with Objects and without material. This research confirms that the TSG in the Canary Islands is a mirror of traditional culture and, from a pedagogical approach, shows great potential for material and social sustainability. (shrink)

The aim of this study is to analyze investor behavior towards socially responsible mutual funds. The analysis is based on an experimental study where a sample of individuals takes investment decisions under different parameters of information about the investment alternatives and expected returns. In the experiment, each participant decides how to distribute an investment budget between two funds, returns on which are uncertain and change over time. Two treatments are conducted, each providing a different degree of information on the socially (...) responsible (SR) character of one of the two investment alternatives. The results obtained suggest that although individuals’ criteria for investment are essentially guided by returns and diversification, participants invest significantly more in a fund when they are explicitly informed about its SR nature. In particular, participants who declare being concerned about SR actually invest significantly more in the SR alternative. Furthermore, the level of SR faithfulness among a small group of investors is such that they invest the main share of their budget in the SR fund, even when the return differential is highly unfavorable. Providing clear information about the SR characteristics of an investment is crucial to help investors express their preferences. (shrink)

With advances in medical science, the concept of agency has received increasing attention in biomedical ethics. However, most of the ethical discussion around definitions of agency has focused either on patients suffering from mental disorders or on patients receiving cutting-edge medical treatments in developed countries. Very little of the discussion around concepts of agency has focused on the situation of patients suffering from common diseases that affect populations worldwide. Therefore, the most widely-used definitions of agency may be not appropriate to (...) analyse common diseases among large populations. The branch of social sciences known as development studies draw on their own definitions of the term agency that may provide a more applicable and accurate way of referring to common and general cases than the definitions currently used in bioethics. Moreover, the psychological Self-Determination Theory may improve the usefulness of these definitions in common situations. This article explains the characteristics and the shortcomings of current bioethical definitions of agency when they are applied to common medical conditions worldwide. A new, value-based concept of agency, informed by development studies, is proposed as more accurate and useful for biomedical ethics. (shrink)

La escritura académica es esencial en la formación universitaria, pero también representa un desafío, ya que los niveles de escritura no siempre son óptimos. Esta investigación describe las percepciones de los estudiantes sobre la escritura académica. Se empleó un enfoque descriptivo no experimental de tipo transversal, aplicando el Cuestionario de Percepción sobre Alfabetización Académica a 295 estudiantes en tres programas universitarios: Educación, Literatura y Lingüística, y Psicología. Los resultados reflejan una apreciación positiva de su competencia comunicativa, considerando que los conocimientos (...) adquiridos han mejorado su proceso de escritura y la identificación de diversos géneros. Al mismo tiempo, reconocen la necesidad de profundizar en las estrategias de escritura. (shrink)

Health has an important role in the achievement of a good quality of life. Many public policies intended to enhance individual and population health. Amartya Sen’s Capability Approach (CA) offers a framework to assess well-being, as well as interventions seeking to increase it. There are, however, important practical challenges that must be faced before applying CA to concrete situations, such as health. One of these challenges is defining whether it is functioning or a capability that is the feature to be (...) assessed. Moreover, some aspects of freedom that are relevant for CA are frequently neglected, such as agency. These aspects must be considered when performing a health assessment using the CA as a framework. A health assessment using the CA as a framework should include indicators based on the achieved dimension (health functioning), resources and conversion factors (health capability), and freedom to achieve (agency).

Our object in this paper is to study the antecedents, contents, implications, and impact of a not well-known or appreciated paper by EHRENFEST in 1911 on the essential nature of the different quantum hypotheses in radiation theory. After a careful analysis of EHRENFEST’s notebooks, correspondence, and publications, we conclude that the essential points of EHRENFEST’s paper were not perceived to a large extent, and hence that its implications were not considered thoroughly. Specifically, we show that EHRENFEST contributed significantly to the (...) clarifications of the differences between PLANCK’s and EINSTEIN’s respective quantum hypotheses, as well as to those of the concepts ‘‘discontinuity,’’ ‘‘quantization,’’ and ‘‘corpuscularity.’’.

‘Reasoning’ can be considered a general concept that, upon speaking, is the ‘enraonar’, a Catalan word that should not be mistaken with ‘explain’ nor with ‘discuss’ which imply more detail, and cover different situations. This article is presented as an essay on the ancient ideal of ‘enraonar’. To that end, it is explained in what sense ‘enraonar’ and reason are one of the most complex phenomena thought has to deal with. Here it is argued that these natural phenomena require a (...) systematic and ‘scientific’ study, and that withoutthis knowledge computer science cannot simulate people’s every-day ‘enraonar’.

I discuss in detail the contents of the adiabatic hypothesis, formulated by Ehrenfest in 1916. I focus especially on the paper he published in 1916 and 1917 in three different journals. I briefly review its precedents and thoroughly analyze its reception until 1918, including Burgers’s developments and Bohr’s assimilation of them into his own theory. I show that until 1918 the adiabatic hypothesis did not play an important role in the development of quantum theory.

It is not possible to talk about bioethics without recognizing the plurality inherent in it. In this sense, the notion of person is important due to its multiplicity of possible interpretations depending on its cultural context. This fact is highlighted in the case of organ transplantation in Japan. While there are many critiques against this procedure from scholars in various fields, those that deal with the problem of brain death are especially problematic. This is because the definition of person that (...) is invoked in such debates does not seem to coincide with how the notion of person has been understood in the Japanese tradition. Hence, investigating the Japanese concept of ningen could be helpful in not only partially clarifying some of the attitudes that exist in Japan towards the notion of brain death, but also to illustrate the need to recognize the plurality of views in modern bioethics.

El cálculo proposicional se basa proposiciones que son tautologías, antilogías y de tipo contingente, construidas con las operaciones de disyunción, conjunción, y negación, así como con el llamado condicional material para trasladar los enunciados condicionales. Con todo ello se obtiene una estructura de álgebra de Boole, que permite equiparar el cálculo proposicional al cálculo algebraico booleano. En parte, la simplificación conceptual que se obtiene resulta de ser el orden parcial del álgebra equivalente a la afirmación del condicional material. Además, con (...) tal metodología cabe ver qué partes del cálculo proposicional clásico pueden trasladarse, aun con limitaciones, a estructuras más débiles y, a la vez, más generales, como son los ortoretículos no booleanos o las álgebras de De Morgan.El cálculo proposicional trata con la deducción. Por ello, el artículo lo desarrolla a partir de un operador de consecuencias en el sentido de Tarski. Ampliado el modelo deductivo, es fácil ver otras consecuencias que las usualmente consideradas en los textos elementales; en particular, se analizan cuatro esquemas de razonamiento deductivo típicos y, entre ellos, se presta especial atención a los usuales Modus Ponens y Modus Tollens. En el caso de las estructuras algebraicas de conjuntos ‘borrosos’, ninguna es de álgebra de Boole ni siquiera de orto-retículo y sólo cabe trabajar, en algunos casos, con álgebras de De Morgan-Kleene. Por lo tanto el cálculo proposicional ‘fuzzy’ debe construirse de acuerdo con la estructura algebraica que corresponda en cada caso y una vez elegida como representación del condicional una función que verifique el Modus Ponens.

We analyze the evolution of EHRENFEST's thought since he proved the necessity of quanta in 1911 until the formulation of his adiabatic hypothesis in 1914. We argue that his research contributed significantly to the solution of critical problems in quantum physics and led to a rigorous definition of the range of validity of BOLTZMANN's principle.

El objetivo de este trabajo es reconsiderar el punto de vista defendido por los pensadores que se pueden adscribir al famoso ‘Círculo de Viena’ sobre el significado y, especialmente, sobre los enunciados asignificativos. Para ello, procedemos usando la típica forma científica, heredera de la tradición del Círculo, de medir empíricamente los conceptos adquiridos. Además, proporcionamos algunas notas históricas, así como algunas reflexiones sobre el pensamiento de Karl Menger sobre la carencia de una geometría adecuada para el micromundo.

En este trabajo repaso la concepción del cuerpo de Nietzsche y de Butler, intentando mostrar cómo cada una nos ayuda a superar un error de la modernidad. Nietzsche nos permite recuperar el cuerpo y contrarrestar el dualismo cartesiano, que lo valora tan poco, convirtiéndolo en una mera máquina. La obra de Judith Butler, por otro lado, especialmente Precarious Life y Frames of War, nos sirve para hacer frente al individualismo, al poner sobre la mesa la socialidad del cuerpo, el modo (...) en que nuestro cuerpo habla de los otros y está expuesto a los otros.

Ofrecemos un estudio introductorio del papel que tuvo el concepto de partícula en los artículos fundacionales de la mecánica cuántica. Nos centramos en el período 1925-1927, lo que incluye el análisis de los primeros trabajos de Heisenberg, Born, Jordan, Schrödinger y Dirac, y también las primeras formulaciones de la complementaridad de Bohr. Nuestro objetivo es discutir hasta qué punto se puso en duda entre los creadores de la nueva teoría, justo en el momento de su creación y cuando aún no (...) existía una interpretación consensuada ni establecida, el concepto de partícula. Posteriores desarrollos, como la teoría cuántica de campos, pusieron la vigencia de ese concepto bajo sospecha. Mostramos que un análisis historiográfico articulado mediante este concepto permite caracterizar la relación que los distintos autores de la mecánica cuántica mantuvieron con la visualización de los procesos atómicos. En algunos casos, como el de Heisenberg, su evolución es especialmente significativa. Asimismo, también citaremos algunos fragmentos donde los autores considerados reclaman para sí el legado de la antigua teoría cuántica, tratando de legitimar sus propios desarrollos a partir de su coherencia con los primeros descubrimientos de los Planck, Einstein o De Broglie. De prácticamente todos ellos hemos encontrado textos en este sentido. (shrink)

This paper provides an interpretation, based on the social systems theory of German sociologist Niklas Luhmann, of the recent paradigmatic shift of mental health care from an asylum-based model to a community-oriented network of services. The observed shift is described as the development of psychiatry as a function system of modern society and whose operative goal has moved from the medical and social management of a lower and marginalized group to the specialized medical and psychological care of the whole population. (...) From this theoretical viewpoint, the wider deployment of the modern social order as a functionally differentiated system may be considered to be a consistent driving force for this process; it has made asylum psychiatry overly incompatible with prevailing social values (particularly with the normative and regulative principle of inclusion of all individuals in the different functional spheres of society and with the common patterns of participation in modern function systems) and has, in turn, required the availability of psychiatric care for a growing number of individuals. After presenting this account, some major challenges for the future of mental health care provision, such as the overburdening of services or the overt exclusion of a significant group of potential users, are identified and briefly discussed.

A partir de reflexiones propuestas por Joseph Roth, Walter Benjamin, Sigfried Kracauer y Claudio Guillén, se presenta el concepto de “ciudad blanca” ligado a la frontera y la centralidad para concluir que la “ciudad blanca” es desfocalizada y periférica, invadida y rebelde, modelo (sueño o proyecto) e infierno (pesadilla o caos). El concepto se aplica al examen de cuatro ciu- dades “blancas” a propósito de secuencias significativas de cuatro films: Los olvidados (1950) de Luis Buñuel, Pizza, birra, faso (1998) de (...)

This article is devoted to give reasons against the naturalization of logic, in a sense which entails a revision of this science. The paper criticizes each historical important attempt to revise logical laws – intuitionism, quantum logic, alternative logics – and also it tries to argue that the explanation problem of quantum mechanics has nothing to do with a naturalization of logic.

One of the most remarkable implications of psychological medicine in the transition from the 18th to the 19th century was the advent of a new way of looking at the human being and new tools for analysing not only behaviour and individual experience, but also historical events, collective behavioural patterns or complex cultural achievements. Unsurprisingly, the deployment of this gaze could not advance without there being a series of disputes and controversies about its reach and the limits to its indiscriminate (...) application. Focusing on the figure of French alienist Alexandre Brierre de Boismont and on the controversial cases of hallucinations and suicide, this article addresses the conflicts generated by the use of certain emblematic concepts and categories present in French psychological medicine throughout the central decades of the 19th-century, as well as the essentially ambivalent relationship of the psychopathological point of view with the criticism of a culture that was made responsible, then, as now, for a great number of psychological disorders and illnesses.

Basadas en un modelo matemático muy simple del razonamiento de sentido común, se presentan algunas reflexiones acerca de lo que podría ser pensar y razonar sin especular. Es decir, si razonar sólo fuese deducir y abducir pero sin inducir.

A través de una serie de ejemplos matemáticos elementales se Ilega a proponer una definición bastante general de Indistinguibilidad, por medio de operadores con valores en semigrupos conmutativos ordenados. Tal definición se aplica a casos provenientes de diversos campos, muchos de los cuales exhiban la propiedad da rotura de las cadenas de objetos relacionados a causa de un cierto parecido.

En el estilo de unas páginas-vividas del periodo 1984-88, y desde lo que permite la memoria del autor, se relatan acontecimientos, algunas de las ideas que estuvieron detrás de ellos y anécdotas sucedidas en ese tiempo. La única intención del artículo es la de ofrecer unos recuerdos que, eventualmente, puedan ayudar a comprender mejor aquellos años.

It can be said that Formal Logic begun by studying an idealization of the statements ’if p, then q’, something coming from long ago in both Greek and Scholastic Philosophy. Nevertheless, only in the XX Century it arrived at a stage of formalization once in 1910 Russell introduced and identified the ’material conditional’ with the expresion ”not p or q”. In 1918, and from paradoxical conditionals like ”If the Moon is a cheese, it is a Lyon’s face”, Lewis critiziced the (...) material conditional and introduced the so-called ’strict conditional’ as the modal necessity of the material one. In 1934, Huntington proved that both material and strict implications are coincidental in the setting of Boolean algebras and, hence, that they only can be actually different in algebraic structures weaker than Boolean algebras. Boolean algebras have too much laws for supporting the difference of both conditionals. This paper is nothing else than an algebraic trial to find simple binary Boolean operations able to express Lewis’ strict implication, and contains a new and simpler proof than that of Huntington, made by identifying ’possible’ with ’non self-contradictory’. By the way, it is shown that this proof is only valid in Boolean algebras, but neither in proper De Morgan algebras, nor in proper Ortholattices, with which it still remains open where the two conditional relations are actually different.

This paper deals with the relation with Fuzzy Logic of some of the ideas of Karl Menger published between 1942 and 1966 and concerning what he called “Hazy Sets”, Probabilistic Relations and Statistical Metric Spaces. The author maintains the opinion that if Lofti A. Zadeh is actually the father of Fuzzy Logic, Menger not only was a forerunner of this field but that his ideas were and still are influential on it.
