El presente artículo trata de enmarcar la economía social y solidaria en el seno del actual debate producto de la crisis económica vigente, haciendo especial hincapié en las cuestiones relacionadas con los bienes comunes y la gestión democrática. La crisis presente ha puesto de manifiesto la necesidad de proponer modelos socio-económicos alternativos que aúnen democracia, compromiso social y sostenibilidad del medio ambiente. La economía social y solidaria, sin ser un programa homogéneo, está contribuyendo a proponer respuestas a algunos de los (...) problemas actuales en materia de desempleo e integración social, revalorizando en los procesos económicos, no sólo los intercambios mercantiles, sino también los intereses sociales y los recursos naturales.This article aims to enlighten the importance ofsolidary and social economy in the present discussion, whose importance has increased as a result of the current economic crisis, making a special emphasis on subjects such as commons goods and democratic management. The crisis has brought up the need for alternative socio-economical management models which must combine democracy, social commitment and environmental sustainability. Solidary and social economy, without being a homogeneous program, are proposing answers to some of the present problems related to unemployment and social integration, contributing to increase the value of economic processes, not only in commercial exchanges, but also the social interest and natural resources.

RESUMENMoviéndose por caminos siempre complejos, la obra de Georges Bataille perdura como una de las más originales del pensamiento francés del siglo XX, donde su influencia ha sido inmensa. El presente artículo quiere mostrar el importante rol que jugarán en su obra las nociones de lo sagrado y de experiencia interior. Dicha experiencia, elemento central para entender su concepción de la religión, representará para Bataille la puesta en tela de juicio de todo lo conocido, pero también la íntima comunicación, ajena (...) al discurso racional, que se establece entre el mundo profano y el mundo sagrado.PALABRAS CLAVESAGRADO, EXPERIENCIA INTERIOR, COMUNICACIÓN, SACRIFICIO, MUERTE.ABSTRACTThe work of Georges Bataille, moving through complex paths, remains as one of the most original works of the twentieth-century French thought, where his influence has been immense. This article aims to show the important role that the notions of sacred and inner experience will play in his work. This experience, the central element for understanding his conception of religion, will represent to Bataille the putting into question all the known, but also the intimate communication, foreign to rational discourse, which is set between the profane and the sacred world.

In this paper we prove that the free algebras in a subvariety equation image of the variety equation image of semi-Heyting algebras are directly decomposable if and only if equation image satisfies the Stone identity.

All paradoxes of self-reference seem to share some structural features. Russell in 1908 and especially Priest nowadays have advanced structural descriptions that successfully identify necessary conditions for having a paradox of this kind. I examine in this paper Priest’s description of these paradoxes, the Inclosure Scheme (IS), and consider in what sense it may help us understand and solve the problems they pose. However, I also consider the limitations of this kind of structural descriptions and give arguments against Priest’s use (...) of IS in favour of dialetheism. IS fails to identify sufficient conditions for having a paradox of self-reference. That means that, even if we identified a problem common to any reasoning satisfying IS, that problem would not explain why some of those reasonings are paradoxical and some others are not. Therefore IS cannot justify by itself the claim that some particular theory offers the best solution to the paradoxes of self-reference. We still need to consider aspects concerning the content and context of occurrence of every paradox. (shrink)

La teoría moderna de la literatura surgió del encuentro, no siempre pacífico, entre la filosofía, la estética y la literatura bajo la influencia dominante de los programas idealistas y románticos. En el período que va desde la publicación del tratado de Schiller Sobre poesía ingenua y sentimental (1795) hasta la aparición de El nacimiento de la tragedia (1872) de Nietzsche, los conceptos poetológicos tradicionales fueron reelaborados en términos especulativos, sustancialistas y trascendentales. A través de una lectura comparada de textos filosóficos (...) y literarios, este libros propone una interpretación de conjunto en la que la teoría moderna de la literatura se caracteriza por una conciencia crítica cuyo ideal de transparencia reflexiva no cesa de conducir a diversas “formas de lo informe”.

The paper highlights the importance of cultivating several trans-cultural human values, and controlling many such dis-values in order to stem the qualitative rot in corporate management. Rights-without-duties refers to an untenable state of affairs. If this is not recognized the free market model may itself be aban doned. According to the author, hierarchical need models of motivation, or contingency theories of leader ship have only temporary superficial effect. Instead, the fundamental psychological principles of the Gita and the Isha Upanishad are (...) deeper and foolproof. The author strongly argues for management with ethics, science with human values, and technology with a conscience. Enlightened managers must acquire wisdom, he concludes. (shrink)

El objetivo de este trabajo es analizar las diversas manifestaciones de transgresión que tienen su origen en los últimos años de la década de los 70 y en los 80 en España, y su reflejo en los estereotipos de género. Desde las actitudes libertarias, pasando por la superwoman como modelo de mujer emancipada, hasta los nuevos modelos de maternidad intensiva que comienzan a introducirse a finales de los ochenta, la transgresión se ha manifestado de diversas formas durante este periodo en (...) el que las españolas a duras penas lograron superar el modelo tradicional impuesto por el franquismo. En este contexto, la transgresión se manifestó como un fenómeno superficial, inherente al momento sociopolítico y vaciada de un contenido reivindicativo. (shrink)

Las antiguas zonas mineras e industriales, muchas de ellas ya abandonadas tras una prolongada actividad extractiva y productiva, albergan frecuentemente buenas experiencias de recuperación del patrimonio asociado y sus paisajes. Impulsados inicialmente los proyectos desde las administraciones públicas, sobre todo de ámbito municipal, con participación activa de las empresas propietarias y la comunidad local, hoy son un extraordinario referente de puesta en valor de un legado muy peculiar que ofrece amplias posibilidades de reutilización bajo la perspectiva irrenunciable del desarrollo sostenible.

La guerra no es una actividad necesariamente sangrienta, pero sí necesariamente política. Esta, en tanto que actividad del espíritu y sentimiento, anida en las mentes de quienes toman parte en ella. En el mundo del siglo XXI el incremento de relaciones e intereses compartidos hace difícil que las guerras puedan ser totales; lo que existe es una zona gris en la que se plasma la rivalidad de los diferentes actores en planos concretos. Narrativas e imágenes son fundamentales como herramientas de (...) persuasión política. En este sentido también son elementos del _Soft Power_, entre ellas la Historia, que puede ser instrumentada como la mejor de las narrativas. Estas permiten controlar la agenda informativa y, a su vez, la realidad, así como crear los sobreentendidos que sirven a las Relaciones Internacionales y ayudan a la implementación de las políticas. El dominio cultural y, sobre todo, la cinematografía son elementos claves en tal propósito, porque no importan los hechos tanto como su percepción, su memoria y recuerdo. (shrink)

El despido intempestivo ha sido uno de los causales con mayor incidencia en el tema laboral, debido que el patrono no establece condiciones claras de la desvinculación, por lo que, se vulnera los derechos de los trabajadores. Elaborar un documento de análisis jurídico crítico que evidencie como la incidencia del despido intempestivo vulnera los derechos laborales Constitucionales en el Ecuador. El artículo fue una revisión sistemática con un diseño transversal. Para la busqueda de información se utilizó las principales platafomas digitalez (...) con evidencia científica en el campo jurídico, además de establecer criterios de inclusión y exclusión para obtener la información con mayor relevancia al estudio. De acuerdo con los casos analizados se evidenció que los despidos intempestivos se los realiza sin una justificación clara, que motive la desvinculación del trabajador vulnerando su derecho a tener una estabilidad laboral, un trabajo digno. A pesar de que la Constitución y las leyes laborales establecen claras protecciones para los trabajadores, la realidad demuestró que estas normativas no siempre se aplican de manera efectiva, lo que no solo socava el derecho a la estabilidad laboral y un trabajo digno, sino que también limita el acceso a la justicia, afectando el bienestar tanto económico como psicoemocional de los dependientes, destacando la necesidad urgente de fortalecer los mecanismos de protección laboral, garantizando la aplicación rigurosa de las leyes existentes en Ecuador.

Charles S. Peirce (1839-1914) made relevant contributions to deductive logic, but he was primarily interested in the logic of science, and more especially in what he called 'abduction' (as opposed to deduction and induction), which is the process whereby hypotheses are generated in order to explain the surprising facts. Indeed, Peirce considered abduction to be at the heart not only of scientific research, but of all ordinary human activities. Nevertheless, in spite of Peirce's work and writings in the field of (...) methodology of research, scarce attention has been paid to the logic of discovery over the last hundred years, despite an impressive development not only of scientific research but also of logic. -/- Having this in mind, the exposition is divided into five parts: 1) a brief presentation of Peirce, focusing on his work as a professional scientist; 2) an exposition of the classification of inferences by the young Peirce: deduction, induction and hypothesis; 3) a sketch of the notion of abduction in the mature Peirce; 4) an exposition of the logic of surprise; and finally, by way of conclusion, 5) a discussion of this peculiar ability of guessing understood as a rational instinct. -/- .

Modern societies increasingly show more egalitarian attitudes related to sexism and gender equality. However, there is still an important gender gap in wages and professions as well as in expectations surrounding male and female characteristics. Developmental studies carried out from an ecological perspective confirm that these influences come from the closest environments (mainly family and school) but also from more distant systems such as media or cultural values. As children are socialized in these norms and values, they increasingly internalize those (...) schemes and use them to judge others, to choose friends and playmates, and to construct expectations of them. On this basis, the aim of this study was to examine the degree of gender bias internalization in a group of Spanish children. Two tasks were applied to a group of 149 public school boys and girls (aged 4–9 years). Results showed that, already from an early age, the participants had internalized traditional gender roles, especially when asked to assign masculine attributes. Moreover, group differences were found given that boys seemed to be more aware of expectations surrounding masculinity and girls assigned the attributes associated with femininity to women more often than boys. Furthermore, a developmental pattern similar to one obtained in previous studies was observed. Younger children already apply gender roles as part of their increasing acquisition of knowledge in the social field, but there is a big increase in the strength of this bias as they grow older. Psychological and educational implications of these findings are discussed, especially considering that the male gender role seems to be more rigid and less malleable. In this regard, developmental and environmental studies should be considered when designing early intervention programs to reduce sexism and to promote equity in schools and families. As research has already shown what type of environments affect children’s acquisition of traditional gender roles, society must make an effort to promote more egalitarian environments that will serve as protective factors in their future psychological, social and professional development.

The dual stream model of the human and non-human primate visual systems remains Leslie Ungerleider's (1946-2020) most indelible contribution to visual neuroscience. In this model, a dorsal "where" stream specialized for visuospatial representation extends through occipitoparietal cortex, whereas a ventral "what" stream specialized for representing object qualities extends through occipitotemporal cortex. Over time, this model underwent a number of revisions and expansions. In one of her last scientific contributions, Leslie proposed a third visual stream specialized for representing dynamic signals related (...) to social perception. This alteration invites the question: What is a visual stream, and how are different visual streams individuated? In this article, we first consider and reject a simple answer to this question based on a common idealizing visualization of the model, which conflicts with the complexities of the visual system that the model was intended to capture. Next, we propose a taxonomic answer that takes inspiration from the philosophy of science and Leslie's body of work, which distinguishes between neural mechanisms, pathways, and streams. In this taxonomy, visual streams are superordinate to pathways and mechanisms and provide individuation conditions for determining whether collections of cortical connections delineate different visual streams. Given this characterization, we suggest that the proposed third visual stream does not yet meet these conditions, although the tripartite model still suggests important revisions to how we think about the organization of the human and non-human primate visual systems.

Karl Marx (1818-1883) was trained as a philosopher and steeped in the thought of Hegel and German idealism, but turned away from philosophy in his mid-twenties towards politics, economics and history. It is for his these subjects Marx is best known and in which his work and ideas shaped the very nature of the nineteenth and twentieth centuries. However, Marx's engagement with philosophy runs through most of his work, especially in his philosophy of history and in moral and political philosophy. (...) In this outstanding introduction to Marx's philosophy Jaime Edwards and Brian Leiter begin with an overview of Marx's life and intellectual development, before examining and assessing the following important topics: Marx's theory of history: Hegel, dialectics, teleology, materialism functionalism and the causal explanation of historical change economics, history and the transition from communism to capitalism ideology, morality and religion human nature, alienation and the good life for human beings Marx's legacy and influence, including Western Marxism and the Frankfurt School. The addition of chapter summaries, annotated further reading and a glossary of technical terms make this an indispensable introduction to Marx's philosophy. It will also be useful to those in related disciplines such as politics, sociology, history and economics. (shrink)

The present article analyzes and compares the idea of divine revelation to justify religious beliefs from the viewpoints of Paul Moser and Mulla Sadra. Moser suggests a kind of moral transformation experience that includes direct cognition and internal experience of self-revelation and God’s unselfish love while he considers mere theoretical reason to be inefficient and emphasizes God’s authority and His attributes and goals as well as the axis of divine revelation. Knowledge-by-presence and direct experience of God in Mulla Sadra’s philosophy (...) which is the only way to access true recognition of God is close to divine revelation. The present article shows that, considering the relationship between love and salvation, and knowledge-by-presence and the practical intellect, in Sadrian belief in God, Moser’s approach is close to Mulla Sadra’s even though the method of argumentation of these two philosophers in representing this type of cognition is not completely the same. Considering the commonalities and differences between Moser and Mulla Sadra in justifying belief in God, it seems possible to revise Moser’s approach with a Sadrian reading with a combination of innate nature arguments and self-knowledge.

Este trabajo tiene como objetivo básico analizar las relaciones entre la arqueología, disciplina que se institucionaliza en Japón durante el período Meiji (1868-1912), y el conjunto de relatos definido como “mitología japonesa”. Como se discute en este artículo, la arqueología japonesa estableció desde sus orígenes dos espacios discursivos, uno creado exclusivamente a partir del conocimiento arqueológico, y otro, de carácter mito-histórico, que se apoyaba en las crónicas compiladas por el poder político durante la Antigüedad. Los estudios mitológicos en un sentido (...) estricto surgen en Japón a principios del siglo XX, una época en la que el nuevo Estado Meiji ya había incorporado el relato mítico a la enseñanza de la historia japonesa. Ante el uso político de esta narrativa, la comunidad arqueológica nipona no constituirá un ente monolítico, variando sus reacciones entre el revisionismo, un ferviente colaboracionismo, y el silencio.

This article investigates the presence of Amazonian imagery in Statius' Achilleid. It begins by uncovering intertexts to Aeneid 1 in the arrival of Ulysses and Diomedes on Scyros ( Ach. 1.726–58), which create a layer of erotic tension that is vital for the interpretation of the ensuing simile comparing Achilles, Deidamia, and Lycomedes' daughters with Amazons ( Ach. 1.758–60). A comprehensive analysis of the simile allows a re-examination of Statius' echoes to the portrayals of Hippolyte and Theseus in Thebaid 12, (...) and draws attention to previously unnoticed parallels with Virgil's Aeneid. The final section of the article examines the broader context of the Amazon simile, eliciting intertextual points of contact with Ovid's Metamorphoses 7 and Valerius Flaccus' Argonautica 5, emphasising in particular the importance of the underlying recruitment theme. Statius' deployment of Amazonian imagery in the Achilleid is seen to be intrinsically tied to the poem's gender fluidity, and the poet's innovative narrative technique. (shrink)

POLITICS is a system of computer programs which simulates humans in comprehending and responding to world events from a given political or ideological perspective. The primary theoretical motivations were: (1) the implemention of a functional system which applies the knowledge structures of Schank and Abelson (1977) to the domain of simulating political belief systems; (2) the development of a tentative theory of intentional goal conflicts and counterplanning. Secondary goals of the POLITICS project include developing a representation for belief systems, investigating (...) cognitive processes such as goal‐directed inferencing, and the integration of several types of knowledge representations into a functional system.

The American novelist Walker Percy (1916-90) considered himself a "thief of Peirce", because he found in the views of C.S. Peirce, the founder of pragmatism, an alternative approach to prevailing reductionist theories in order to understand what we human beings are and what the peculiar nature of our linguistic activity is. -/- This paper describes, quoting widely from Percy, how abduction is the spontaneous activity of our reason by which we couple meanings and experience in our linguistic expressions. This coupling (...) of personal creativity and cultural tradition makes it possible to bridge the gaps between persons and cultures. (shrink)

International large-scale assessments, such as PISA, provide structured and static data. However, due to its extensive databases, several researchers place it as a reference in Big Data in Education. With the goal of exploring which factors at country, school and student level have a higher relevance in predicting student performance, this paper proposes an Educational Data Mining approach to detect and analyze factors linked to academic performance. To this end, we conducted a secondary data analysis and built decision trees (C4.5 (...) algorithm) to obtain a predictive model of school performance. Specifically, we selected as predictor variables a set of socioeconomic, process and outcome variables from PISA 2018 and other sources (World Bank, 2020). Since the unit of analysis were schools from all the countries included in PISA 2018 (n= 21,903), student and teacher predictor variables were imputed to the school database. Based on the available student performance scores in Reading, Math, and Science, we applied k-means clustering to obtain a categorized (three categories) target variable of global school performance. Results show the existence of two main branches in the decision tree, split according to the schools’ mean socioeconomic status (SES). While performance in high-SES schools is influenced by educational factors such as metacognitive strategies or achievement motivation, performance in low-SES schools is affected in greater measure by country-level socioeconomic indicators such as GDP, and individual educational indicators are relegated to a secondary level. Since these evidences are in line and delve into previous research, this work concludes by analyzing its potential contribution to support the decision making processes regarding educational policies.

This paper presents a new two-dimensional Multiple-Choice Model accounting for Omissions (MCMO). Based on Thissen and Steinberg multiple-choice models, the MCMO defines omitted responses as the result of the respondent not knowing the correct answer and deciding to omit rather than to guess given a latent propensity to omit. Firstly, using a Monte Carlo simulation, the accuracy of the parameters estimated from data with different sample sizes (500, 1,000, and 2,000 subjects), test lengths (20, 40, and 80 items) and percentages (...) of omissions (5, 10, and 15%) were investigated. Later, the appropriateness of the MCMO to the Trends in International Mathematics and Science Study (TIMSS) Advanced 2015 mathematics and physics multiple-choice items was analyzed and compared with the Holman and Glas' Between-item Multi-dimensional IRT model (B-MIRT) and with the three-parameter logistic (3PL) model with omissions treated as incorrect responses. The results of the simulation study showed a good recovery of scale and position parameters. Pseudo-guessing parameters ( d ) were less accurate, but this inaccuracy did not seem to have an important effect on the estimation of abilities. The precision of the propensity to omit strongly depended on the ability values (the higher the ability, the worse the estimate of the propensity to omit). In the empirical study, the empirical reliability for ability estimates was high in both physics and mathematics. As in the simulation study, the estimates of the propensity to omit were less reliable and their precision varied with ability. Regarding the absolute item fit, the MCMO fitted the data better than the other models. Also, the MCMO offered significant increments in convergent validity between scores from multiple-choice and constructed-response items, with an increase of around 0.02 to 0.04 in R 2 in comparison with the two other methods. Finally, the high correlation between the country means of the propensity to omit in mathematics and physics suggests that (1) the propensity to omit is somehow affected by the country of residence of the examinees, and (2) the propensity to omit is independent of the test contents.

Cognitive diagnosis models (CDMs) allow classifying respondents into a set of discrete attribute profiles. The internal structure of the test is determined in a Q-matrix, whose correct specification is necessary to achieve an accurate attribute profile classification. Several empirical Q-matrix estimation and validation methods have been proposed with the aim of providing well-specified Q-matrices. However, these methods require the number of attributes to be set in advance. No systematic studies about CDMs dimensionality assessment have been conducted, which contrasts with the (...) vast existing literature for the factor analysis framework. To address this gap, the present study evaluates the performance of several dimensionality assessment methods from the factor analysis literature in determining the number of attributes in the context of CDMs. The explored methods were parallel analysis, minimum average partial, very simple structure, DETECT, empirical Kaiser criterion, exploratory graph analysis, and a machine learning factor forest model. Additionally, a model comparison approach was considered, which consists in comparing the model-fit of empirically estimated Q-matrices. The performance of these methods was assessed by means of a comprehensive simulation study that included different generating number of attributes, item qualities, sample sizes, ratios of the number of items to attribute, correlations among the attributes, attributes thresholds, and generating CDM. Results showed that parallel analysis (with Pearson correlations and mean eigenvalue criterion), factor forest model, and model comparison (with AIC) are suitable alternatives to determine the number of attributes in CDM applications, with an overall percentage of correct estimates above 76% of the conditions. The accuracy increased to 97% when these three methods agreed on the number of attributes. In short, the present study supports the use of three methods in assessing the dimensionality of CDMs. This will allow to test the assumption of correct dimensionality present in the Q-matrix estimation and validation methods, as well as to gather evidence of validity to support the use of the scores obtained with these models. The findings of this study are illustrated using real data from an intelligence test to provide guidelines for assessing the dimensionality of CDM data in applied settings. (shrink)

Resumen: Este artículo tiene como objetivo ofrecer al lector un análisis de las figuras antropomorfas conocidas como dogū, que fueron elaboradas durante el período Jōmon de la prehistoria japonesa. Para ello, en primer lugar, será necesario esclarecer sus orígenes y evolución a partir del conocimiento arqueológico acumulado hasta la actualidad, que pondrá de relieve un proceso gradual de complejización tipológica, desde formas primarías hasta un intento de trascender la representación del cuerpo humano. Al mismo tiempo, también se deberá prestar atención (...) a su diversidad sincrónica, marcada por diferentes tipos con una mayor o menor presencia en el marco espacial del archipiélago. Esta labor permitirá no sólo delimitar las diferentes etapas protagonizadas por estas figuras, sino también esclarecer su posible significado y uso. Ello nos conducirá finalmente a un replanteamiento sobre la propia existencia de los dogū como categoría arqueológica. (shrink)

In this article, I use Object Oriented Ontology’s (OOO) account of metaphor as a perspective on the topic of hypnosis and some related phenomena. This analysis shows the potential of OOO’s theory of aesthetics to be informative outside of the usual realm of aesthetics, while simultaneously highlighting some of its shortcomings. Understanding hypnosis from this aesthetic point of view can be illustrative of the ways in which our experience is more generally mediated by factors outside of our conscious awareness. In (...) particular, I will take advantage of this understanding to convey a message of caution regarding how we carry out psychological experiments and scientific research at large. At the same time, the connections drawn in this work highlight the central role played by social dimensions in aesthetic situations and should serve to highlight the need to bring forth such dimensions when thinking about aesthetics in OOO.
