Interaction and imitation in a world of Quixotes and Sanchos

Producción CientíficaThis paper studies a two-population evolutionary game in a new setting in between a symmetric and an asymmetric evolutionary model. It distinguishes two types of agents: Sanchos, whose payoffs are defined by a prisoner’s dilemma game, and Quixotes, whose payoffs are defined by a snowdrift game. Considering an imitative revision protocol, a revising agent is paired with someone from his own population or the other population. When matched, they observe payoffs, but not identities. Thus, agents in one population interact and imitate agents from their own population and from the other population. In this setting we prove that a unique mixed-strategy asymptotically stable fixed point of the evolutionary dynamics exists. Taking as an example the compliance with social norms, and depending on the parameters, two type of equilibrium are possible, one with full compliance among Quixotes and partial compliance among Sanchos, or another with partial compliance among Quixotes and defection among Sanchos. In the former type, Sanchos comply above their Nash equilibrium (as they imitate compliant Quixotes). In the latter type, Quixotes comply below their Nash equilibrium (as they imitate defecting Sanchos)

Thionins

The general designation of thionins has been proposed for a family of homologous peptides that includes purothionins, which were first isolated from wheat seeds (Balls el #/., 1942) and their homologues from various taxa that have been named viscotoxins and crambins (see Garcia-Olmedo el al., 1989). The crystalline protein material obtained from lipid extracts of wheat endosperm was designated "purothionins" because of its high sulphur content (Balls el al., 1942). This material was found to have bactericidal and fungicidal properties (Stuart and Harris, 1942), to inhibit fermentation of wheat mashes (Balls and Harris, 1944), and to be toxic to laboratory animals (Coulson el al„ 1942). The toxic properties of mistletoes were ascribed to the viscumin lectin and to a mixture of small basic proteins, designated - "viscotoxins" (Samuelsson, 1974). In a study of the seeds of the Abyssinian cabbage {Crambe abyssinica)^ a high-sulphur crystalline protein was obtained from the aqueous acetone extracts and designated "crambin" (Van Ettcn e/<?/., 1965)

El Ritual de la muerte en Zalamea la Real en la segunda mitad del siglo XVIII

En la sociedad zalameña de la seguunda mitad del siglo XVIII, perfectamente jerarquizada, seguía manteniéndose el ritual funerario barroco, encontrándose diferencias tanto a nivel de grupos sociales como de sexo de los otorgantes. Las clases populares intentaron emular, en la medida de los posible, la ostentación de los grupos privilegiados, y fueron las mujeres las que lo perpetuaron de una manera más eficaz, ya que sobre ellas era mayor la influencia de los clérigos que residían en la villa, entre otras cosas.__________________________________In a society like Zalamea's, which was entirely hierarchical, during the second half of the XVIIIth century, the baroque ritual of funeral ceremonies was still maintained, so it is possible to find differences in terms of both social groups and sex. Lower classes would try to imitate, as far as possible, the ostentation of the privileged, and it was women that would accomplish the ritual more effectively, partly because they were more influenced by the high number el clergymen who lived in the village

Minimal formulation of the linear spatial analysis of capillary jets: Validity of the two-mode approach

A rigorous and complete formulation of the linear evolution of harmonically stimulated capillary jets should include infinitely many spatial modes to account for arbitrary exit conditions [J. Guerrero et al., J. Fluid Mech. 702, 354 (2012)]. However, it is not rare to find works in which only the downstream capillary dominant mode, the sole unstable one, is retained, with amplitude determined by the jet deformation at the exit. This procedure constitutes an oversimplification, unable to handle a flow rate perturbation without jet deformation at the exit (the most usual conditions). In spite of its decaying behavior, the other capillary mode (subdominant) must be included in what can be called a “minimal linear formulation.” Deformation and mean axial velocity amplitudes at the jet exit are the two relevant parameters to simultaneously find the amplitudes of both capillary modes. Only once these amplitudes are found, the calculation of the breakup length may be eventually simplified by disregarding the subdominant mode. Simple recipes are provided for predicting the breakup length, which are checked against our own numerical simulations. The agreement is better than in previous attempts in the literature. Besides, the limits of validity of the linear formulation are explored in terms of the exit velocity amplitude, the wave number, the Weber number, and the Ohnesorge number. Including the subdominant mode extends the range of amplitudes for which the linear model gives accurate predictions, the criterion for keeping this mode being that the breakup time must be shorter than a given formula. It has been generally assumed that the shortest intact length happens for the stimulation frequency with the highest growth rate. However, we show that this correlation is not strict because the amplitude of the dominant mode has a role in the breakup process and it depends on the stimulation frequency.Ministerio de Economía, Industria y Competitividad, Spain, under Contract No. FIS2014-25161Junta de Andalucía under Contract No. P11-FQM-791

Una retórica de la publicidad: de la naturaleza inventiva a la verdad metafórica

The subject of rhetoric is all the realities. It impregnates not only the language, but also thought and action. Rhetoric and advertising are discourses and languages; and language is the home of being (Heidegger), through which we access to the knowledge of the object. The advertising message expressive power springs up largely from rhetorical devices as substitution. The elements of a substitution seem to require an account of similarity between them. Something must be replaced and the contribution must be something new. The metaphor is a figure of speech replacement for excellence and is based on the relationship of similarity and solidarity between the terms of the replacement to represent being. Advertising creates the concept and the concept refers to the subject of advertising, or to the products, services or brand. The concept invented the object in that regard has been created by powers from the rhetoric, and for that invention relies on the figures of classical rhetoric and resources to build the invention. The metaphor encourages its existence as a rhetorical device, in addition to replacement, its relationship to reality and the concept of metaphorical truth. Advertising makes the product easier to understand and more desirable. It creates the conditions for credibility to attach an identity to the original product, offers a new and attractive view. Advertising is the art of persuading selling.La materia de la retórica son todas las realidades. Impregna no sólo el lenguaje, sino también el pensamiento y la acción. La retórica como la publicidad son discursos y lenguajes, y el lenguaje es la casa del ser (Heidegger), a través del cual accedemos al conocimiento del objeto. La fuerza expresiva del mensaje publicitario se extrae en gran medida de procedimientos retóricos como la sustitución. Los elementos de la sustitución, lo sustituido y lo sustituyente, parecen exigir una relación de semejanza entre ellos. Algo debe de quedar del sustituido y algo debe ser aportación nueva. La metáfora es la figura retórica de sustitución por excelencia y se funda en la relación de semejanza y solidaridad entre los términos de la sustitución para representar así al ser. La publicidad crea el concepto y el concepto remite al objeto de la publicidad, o sea, a los productos, a los servicios, a la marca. El concepto inventa el objeto en cuanto que ha sido transido por las atribuciones desde el discurso retórico, y para esa invención recurre a la figuras de la retórica clásica como recursos para construir la invención. La metáfora motiva su existencia como recurso, además de en su naturaleza sustituyente, en su relación con la realidad y el concepto de verdad metafórica. La publicidad hace más inteligible el producto y más deseable. Crea las condiciones de verosimilitud y credibilidad concediendo una identidad original al producto, ofrece una perspectiva nueva y atractiva. La publicidad es el arte de vender persuadiendo

The Arabic Language and Moroccan Culture (LACM) Hispano-Moroccan learning program submitted to revision. Moroccan Arabic and Amazigh, native languages (L1)

Presentamos en este trabajo una reflexión sobre la necesidad de tener en cuenta la lengua nativa o materna del alumno en la escuela. Para ello, proponemos que el programa hispano-marroquí de enseñanza de la Lengua Árabe y Cultura Marroquí (LACM) revise sus objetivos e incluya como lengua de enseñanza el árabe marroquí o el amazige (L1), y no el árabe literal (L2). La enseñanza del español (L2) debe de llevarse a cabo en una situación de bilingüismo aditivo y desde unos principios de democracia y no desde la soberanía monolingüe de la L2, ya sea el español, ya el árabe literal. We present in this work a reflection about the need of taking into account the native or mother language of the student in the school. For this reason, we propose that the Hispano-Moroccan learning Program of Arabic Language and Moroccan Culture (LACM) reviews its objectives and includes the Moroccan Arabic or the Amazigh (L1) as language of learning instead of the Standard Arabic (L2). The learning of Spanish (L2) has to be done in a situation of additive bilingualism and founded on democratic principles and not from the monolingual sovereignty of the L2, either the Spanish or the Standard Arabic
