We investigate whether age profiles of ethnobiological knowledge development are consistent with predictions derived from life history theory about the timing of productivity and reproduction. Life history models predict complementary knowledge profiles developing across the lifespan for women and men as they experience changes in embodied capital and the needs of dependent offspring. We evaluate these predictions using an ethnobiological knowledge assessment tool developed for an off-grid pastoralist population known as Choyeros, from Baja California Sur, Mexico. Our results indicate that (...) while individuals acquire knowledge of most dangerous items and edible resources by early adulthood, knowledge of plants and animals relevant to the age and sex divided labor domains and ecologies (e.g., women’s house gardens, men’s herding activities in the wilderness) continues to develop into middle adulthood but to different degrees and at different rates for men and women. As the demands of offspring on parents accumulate with age, reproductive-aged adults continue to develop their knowledge to meet their children’s needs. After controlling for vision, our analysis indicates that many post-reproductive adults show the greatest ethnobiological knowledge. These findings extend our understanding of the evolved human life history by illustrating how changes in embodied capital and the needs of dependent offspring predict the development of men’s and women’s ethnobiological knowledge across the lifespan.

This study investigates priming in an implicit Word Stem Completion (WSC) task. A total of 305 participants performed a WSC task in two phases (study and test). The test phase included 63 unique-solution stems and 63 multiple-solution stems. After confirming the presence of priming (mean = 0.22), analysis revealed that it was stronger in the case of multiple-solution stems, indicating that the stems were not a homogeneous group of stimuli. Thus, further analyses were performed only for the data of the (...) unique-solution stems. The correlations between priming and a set of conceptual (familiarity, frequency of use, number of meanings) and non-conceptual (letters/blanks ratio and difficulty of completed) variables showed significant relationships between two conceptual variables (familiarity and frequency) and priming. Difficulty was also significantly correlated with priming. The most familiar and frequent words were those that produced a greater magnitude of priming. At the same time, the most difficult stems were those generating more priming. A regression analysis showed that the difficulty of completing a stem was the strongest predictor of priming. When difficulty was the dependent variable in the regression analysis, the significant variables in the regression were familiarity and letters-blanks ratio. Finally, a comparison was made between these results and those obtained in a previous study of WFC by Soler et al. (2009) in which the same words and procedure were employed. A comparison of results from these two sets of data suggested that the only relevant difference between the two tasks was the influence of the variable letters-blanks ratio. This perceptual variable had a significant correlation with priming only in the WFC task. These results highlight the importance of controlling the characteristics (conceptual and non-conceptual) of stimuli used in WFC and WSC tasks when exploring the nature of priming. (shrink)

En los primeros años del siglo XIV se planteó la polémica entre los franciscanos “espirituales” y el papa Juan XXII. El emperador alemán Luis de Baviera intervino en la confrontación a favor de los franciscanos y en contra del Papa. En la novela El nombre de la Rosa de Umberto Eco, se escenifica el conflicto entre el Franciscano Guillermo, que representa a Guillermo de Ockham y el inquisidor dominico Bernardo de Guí. En sus páginas se cita la filosofía de (...) Aristóteles, Tomás de Aquino Buenaventura de Bagnoregio, Marsilio de Padua y el propio Guillermo de Ockham. La filosofía política y el conocimiento científico de la época: Alberto Magno y Roger Bacon entre otros completan el panorama del citado siglo XIV. Todo ello demuestra una labor educativa incuestionable del libro de Umberto Eco. (shrink)

El presente trabajo muestra un posible e inmediato ejemplo precursor del Patio de los Leones de la Alhambra de Granada. El monasterio de Santa Clara de Tordesillas fue un importante palacio construido por el rey de Castilla Pedro I en la década de los cincuenta del siglo xiv. En su interior existía un patio con pabellones adelantados de su eje principal. Al poco tiempo, Muhammad V, amigo del rey castellano, erigió después de 1362 el Palacio y el Patio de Los (...) Leones de la Alhambra. Mientras que en Tordesillas se dispuso una alberca en su centro, en Granada se optó por la solución del patio de crucero. La fórmula de los pabellones desplegada en el palacio de Pedro I tuvo que tomarse de los lavabos monumentales de los monasterios cistercienses cercanos. Gracias a las buenas relaciones existentes entre los dos monarcas, la solución pudo ser llevada de Tordesillas a Granada por artistas que estuvieran trabajando para los dos reinos. (shrink)

ABSTRACT In this article we analyze the attempt that young Simone Weil made for thinking time and change, and for deciphering the participation that the world and the mind may have in its configuration. To achieve this, we set out to elucidate two concepts that we believe synthesize her approach: the first one is astonishment, understood both in its quality of incessant intuition that reveals the human impotence to understand the present, and in its quality as a mediating instance between (...) ignorance and approximate human science of the phenomenal field. The second concept we analyze is that of directed time, significant of the first Weilian philosophy in that it reveals the subjugation of man to the present, the only tangible time. This determination allows us to understand the meaning of the past as an abolished existence, and the future as a virtual nucleus of possibilities towards which the human being prepares his action and work thanks to his faculty to devise projects. Finally, we try to show the problematic tension that young Weil discerned between the law of the immediacy of the world, and the law of time that imposes intermediate steps to the realization of all human activity.

Resumen La cuestión del tiempo es uno de los principales objetos de estudio que ocuparon a Simone Weil. En efecto, está intensamente presente en su obra desde sus primeros textos hasta sus últimos escritos. La razón es de peso: para esta autora es a través del tiempo que accedemos a la realidad y a toda posibilidad de sentido en sta. Ahora bien, nuestra intención es mostrar que si bien es cierto que la concepción del tiempo de S. Weil, en sus (...) años de madurez, se erige desde una perspectiva espiritualista, mística y religiosa, en su primera época la filósofa se instala en una ontológica fuertemente influenciada por Kant, que la lleva a restringir lo temporal al marco de la experiencia posible, en el sentido que le da el pensador alemán.The question of time is one of the most important subjects in Simone Weil’s philosophy. Indeed, time’s issue is intensively present in her works from her earlier texts until her last writings. This can be explained by the fact that, for this author, it is through time that we can access to reality and find any sense into the latter. That being said, our goal is to show that, if certainly it can be affirmed that S. Weil’s conception of time in her maturity years is constructed from a spiritual, mystic and religious perspective, at the opposite, in her first period, the philosopher settles her views through an ontology strong influenced by Kant, which conducts her to limited temporal matters into the frame of possible experience, according to the definition of this expression given by the German thinker.

Resumen: En este trabajo estudiamos la génesis de la concepción de la percepción de Simone Weil. Apoyándonos en algunos textos clave de juventud de la autora, hacemos el seguimiento al manejo que le da la filósofa a la figura mitológica de Proteo y a las nociones de tiempo y espacio. Así, nuestra intención es evidenciar la aparición de los principales fundamentos teóricos que estructurarán la fenomenología weiliana de los años de madurez.2 En este sentido, intentamos demostrar en particular que si (...) bien el proceso perceptivo weiliano de los años de juventud está determinantemente influenciado por la fenomenología kantiana, aparece ya un aporte original en lo que atañe a la relación de la conciencia del sujeto y los datos espaciotemporales que se le revelan al aprehender el objeto.: In this work we study the genesis of Simone Weil's conception of perception. We discuss her use of the notions of time, space, and the mythological figure of Proteus, analyzing some of the author's key early texts. Our goal is to then make clear the appearance of the main important theoretical bases that organize Weil's phenomenology in her mature years. In this way, we try to demonstrate that although the perceptive process as conceived by the young Weil is strongly influenced by Kantian phenomenology, it already appears as an original contribution with regard to the relation between the consciousness of the subject and the spatiotemporal data revealed in the apprehension of the object.

The ‘participatory turn’ in science and technology governance has resulted in the growth of initiatives designed to engage lay people in consultation and decision-making on controversial matters. Almost from the start there has been both enthusiasm and serious critique of these exercises, from scholars and activists. The gaps and challenges are well known. In this paper we indicate the limitations of deliberative mechanisms as regards how they cope with familiar forms of people’s engagement with a given matter. We examine how (...) this phenomenon unfolded at the Barcelona Citizen Conference on the Digitalization of Society; a participatory exercise inspired by the model of consensus conferences that took place in 2014 in Barcelona. Our perspective on the topic is inspired by Sociology of Engagements. Focusing on how participants and organizers deal with individual anecdotes, worries and testimonies reported during the conference, the analysis shows how these formats are ignored, externalized, banned and re-formed during deliberations. This phenomenon is seen as supporting a civic-liberal regime of engagement. (shrink)

In the present paper we study the framework of additive utility theory, obtaining new results derived from a concurrence of algebraic and topological techniques. Such techniques lean on the concept of a connected topological totally ordered semigroup. We achieve a general result concerning the existence of continuous and additive utility functions on completely preordered sets endowed with a binary operation ``+'', not necessarily being commutative or associative. In the final part of the paper we get some applications to expected utility (...) theory, and a representation theorem for a class of complete preorders on a quite general family of real mixture spaces.

This paper explores the concept of a social evaluation functional in the case of an arbitrary set of alternatives. In the first part, a characterization of projective social evaluations functionals is shown whenever the common restricted domain is the set of all bounded utility functions equipped with the supremum norm topology. The result makes a crucial use, among others, of a continuity axiom. In the second part, a comparison meaningful property is introduced for a social evaluation functional which allows us (...) for obtaining a more general result with no continuity requirements. Finally, an impossibility theorem, which is reminiscent of that is obtained by Chichilnisky in (Q J Econ 97:337–352, 1982) but without using topological conditions, is offered. (shrink)

Metallothioneins (MTs) are ubiquitous proteins with the capacity to bind heavy metal ions (mainly Cd, Zn or Cu), and they have been found in animals, plants, eukaryotic and prokaryotic micro‐organisms. We have carried out a comparative analysis of ciliate MTs (Tetrahymena species) to well‐known MTs from other organisms, discussing their exclusive features, such as the presence of aromatic amino acid residues and almost exclusive cysteine clusters (CCC) present in cadmium‐binding metallothioneins (CdMTs), higher heavy metal‐MT stoichiometry values, and a strictly conserved (...) modular–submodular structure. Based on this last feature and an extensive gene duplication, we propose a possible model for the evolutionary history of T. thermophila MTs. We also suggest possible functions for these MTs from consideration of their differential gene expressions and discuss the potential use of these proteins and/or their gene promoters for designing molecular or whole‐cell biosensors for a fast detection of heavy metals in diverse polluted ecosystems.

El problema mente-cerebro tiene importantes repercusiones antropológicas. El autor enfoca el problema desde las claves de la antropología cristiana: el valor absoluto del hombre (imago dei"), la libertad y supervivencia postmortem, que en el cristianismo es de la resurrección. Repasa las soluciones a la relación mente-cerebro incompatibles con el cristianismo, y expone el modo de entenderlo en este ultimo. La mente, entendida de manera no dualista, sino como principio estructurante del cuerpo, posibilita una comprensión del ser humano en sintonía con (...) las convicciones practicas de neustro (la idea de dignidad humana), que las soluciones cientistas en boga no tienen mas remedio que impugnar.

The counterfactual thinking cannot be only developed in early childhood, but it also could be a requirement for the causal reasoning. In this research a replica of German was made using counterfactual stories with Latin American kids between three and four years, demonstrating the possible main role counterfactual reasoning, by using computer animations. This was a different approach to the most recent made by Nyhout and Ganea. Nonetheless, the participants of the study evidenced counterfactual reasoning to the relevant choice and (...) the negative consequence conditions shown on the stories that represented the choices made by a starting role. Although some of the results were not totally conclusive under the analyzed conditions. Lastly, some possible not controlled effects are discussed from stories shown to the children, that could have motivated the counterfactual thinking. (shrink)

The aim of our experiment was to analyse the effect of the emotional valence (positive, negative, or neutral) on true and false recognition, matching the arousal, frequency, concreteness, and associative strength of the study and recognition words. Fifty younger adults and 46 healthy older adults performed three study tasks (with words of different valence: positive, negative, neutral) and their corresponding recognition tests. Two weeks later, they performed the three recognition tests again. The results show that words with a negative valence (...) produced less true recognition and less false recognition than words with a positive or neutral valence, in both younger and older adults, on the immediate recognition test. This pattern of results was also found in the younger adults on the delayed recognition test, whereas in the older participants, these differences disappeared. Thus, when arousal is controlled, both younger and older adults tend to recognise negative information worse than positive or neutral information, but they also commit fewer errors. Results would suggest that the greater arousal commonly associated with negative stimuli, rather than their own valence, could explain some of the contradictory results found in the literature.

Flexibility is a desired characteristic that people must have to adjust to inevitable processes of economic, cultural, and political globalization. Engineering education reform is often used as a justification for changes in curricula, delivery modes, and problem solving that should lead to curriculum integration, modular pedagogies, and systemic reform. Some educators have incorporated the concept in their programs and courses in a variety of ways whereas others have resisted changes to this day. Yet a detailed analysis of the meanings of (...) flexibility, its origins and different forms, along with its challenges and opportunities for engineering education, remains to be done. This article surveys the historical origins of flexibility, identifies different forms of flexibility in engineering education, outlines existing challenges to flexibility-drive educational reform, and provides alternative views to the existing interpretation of flexibility in engineering education.

In this paper we investigated how justifications for price increases are associated with risky decision making and emotional responses. Across two studies with paired lottery choices and sequential decisions, we found that participants presented with a justification for price increases based on increasing demand decided to invest in a comparatively riskier asset more often than participants presented with a justification for price increases based on increasing tax or those presented with no justification at all. We also found that participants presented (...) with justifications for price increases based on increasing demand also reported more arousal displayed higher galvanic skin response than people in the other two justification conditions. Together, these studies provide evidence that the sole increasing demand underlying a price increase of a risky asset can influence the decision to buy it and suggests that emotional activation is involved in such a decision process.

Prosocial behavior and its effects have been analyzed in times of crisis and natural disasters, although never before in the face of such exceptional circumstances as those created by the COVID-19 pandemic. This research analyzes the role of PsB on satisfaction with life in Colombia, considering the negative emotional impact of events that began in February 2020. We conduct an exploratory analysis using a sample of Colombia’s general population with an average age of 44.66 years. Using the Classification Tree technique, (...) we find that engaging in one or more PsBs enhances SWL and decreases the impact of negative emotions such as pessimism, indecisiveness, and irritability that have emerged during the COVID-19 pandemic. These findings are significant because they confirm the importance of life satisfaction as a personal resource for coping with complex situations and provide evidence of the benefits of PsB on one’s wellbeing.

The initial stage for the discussion is the distinction between bona fide and fiat objects drawn by Barry Smith and collaborators in the context of formal ontology. This paper aims at both producing a rationale for introducing a hitherto unrecognized kind of object—here called ‘Interactive Fiat Objects’ (IFOs)—into the ontology of objects, and casting light on the relationship between embodied cognition and interactive ontology with the aid of the concepts of affordance and ad hoc category. I conclude that IFOs are (...) similar to fiat objects, affordances and ad hoc categories in a number of ways, yet they differ from these in important respects. Interaction is key to understanding the existence and peculiarities of IFOs. By adopting an embodied perspective on cognition, we can enrich our ontological typologies and highlight relevant features of our physical and symbolic environment that are otherwise overlooked. This should improve our understanding of object ontology and persuade us to include IFOs in our metaphysical inventories. (shrink)

A new proof style adequate for modal logics is defined from the polynomial ring calculus. The new semantics not only expresses truth conditions of modal formulas by means of polynomials, but also permits to perform deductions through polynomial handling. This paper also investigates relationships among the PRC here defined, the algebraic semantics for modal logics, equational logics, the Dijkstra???Scholten equational-proof style, and rewriting systems. The method proposed is throughly exemplified for S 5, and can be easily extended to other modal (...) logics. (shrink)

We prove that if GCH holds and τ = 〈κα : α < η 〉 is a sequence of infinite cardinals such that κα ≥ |η | for each α < η, then there is a cardinal-preserving partial order that forces the existence of a scattered Boolean space whose cardinal sequence is τ.

RESUMENLa teoría representacional de la mente, basada en el concepto de representación, ha sido muy criticada, especialmente por recientes enfoques en la ciencia cognitiva, provenientes de la Biología y la Inteligencia Artificial. En este trabajo me centro especialmente en el punto de vista de Francisco Varela, quien sugiere la exclusión del término representación en la explicación de los sistemas cognitivos. Muestro que ello no es necesario, y que hay razones para hablar de representaciones en la relación que tenemos con el (...) mundo en términos de conocimiento, por tanto, el antirrepresentacionalismo de Varela es inadecuado. En ese sentido me parece más afortunada la apreciación que hacen de la ciencia cognitiva y la filosofía de la mente Andy Clark y Pascual Martínez-Freire, y ésta es la postura que defenderé en contra de Varela.PALABRAS CLAVEMENTE, REPRESENTACIÓN, COGNITIVISMO, CONDUCTA, SISTEMAABSTRACTThe representational theory of the mind, based on the concept of representation, has been very criticized, specially by recent approaches to cognitive science, originated from Biology and Artificial Intelligence.

Overview The evolution of multicellularity raises questions regarding genomic and developmental commonalities and discordances, selective advantages and disadvantages, physical determinants of development, and the origins of morphological novelties. It also represents a change in the definition of individuality, because a new organism emerges from interactions among single cells. This volume considers these and other questions, with contributions that explore the origins and consequences of the evolution of multicellularity, addressing a range of topics, organisms, and experimental protocols. Each section focuses on (...) selected topics or particular lineages that present a significant insight or challenge. The contributors consider the fossil record of the paleontological circumstances in which animal multicellularity evolved; cooptation, recurrent patterns, modularity, and plausible pathways for multicellular evolution in plants; theoretical approaches to the amoebozoa and fungi (cellular slime molds having long provided a robust model system for exploring the evolution of multicellularity), plants, and animals; genomic toolkits of metazoan multicellularity; and philosophical aspects of the meaning of individuality in light of multicellular evolution.
