© 2016 Elsevier LtdJumping spiders are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level. Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds by freezing—a common (...) anti-predatory behavior characteristic of an acoustic startle response. Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones —recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. Thus, these spiders appear able to detect airborne sound at distances in the acoustic far-field region, beyond the near-field range often thought to bound acoustic perception in arthropods that lack tympanic ears [2]. Furthermore, direct mechanical stimulation of hairs on the patella of the foreleg was sufficient to generate responses in neural units that also responded to airborne acoustic stimuli—evidence that these hairs likely play a role in the detection of acoustic cues. We suggest that these auditory responses enable the detection of predators and facilitate an acoustic startle response. Video. (shrink)

El cordobés Damián de Castro, gran exponente de la platería rococó española en la centuria dieciochesca, realizó junto a otros artífices diferentes piezas para el cardenal Delgado y Venegas, arzobispo hispalense entre 1776 y 1781. Hoy muchas de estas piezas las podemos contemplar en las vitrinas de nuestro museo catedralicio, sin embargo la existencia en su tiempo de diferentes piezas similares produjo cierta confusión en su posterior identificación. En este nuevo trabajo intentaremos desentrañar las dudas sobre dos de las más (...) vistosas piezas del tesoro de nuestro templo mayor: las dos bandejas de plata sobredorada que, ejecutadas en un exuberante y depurado rococó, deslumbran al visitante con sus fúlgidos destellos y atrevido diseño.

This study seeks to examine the impact of alumni connections between the evaluators and evaluatees on the results of peer review ratings for the Korean national R&D project and selection success rate. Specifically, this study analyzed the evaluation results of 8,402 research proposal entries submitted between 2007 and 2011 for the “general researchers support project,” all in the Natural Science and Engineering areas and sponsored by the National Research Foundation of Korea. Each proposal entry was evaluated by three evaluators, and (...) approximately 39 percent of the proposals had at least one evaluator from the same university. The results of this study showed that evaluators have a tendency to give relatively high scores to research proposals submitted by the alumni of the same universities as their alma mater. Also, when an evaluator from the same university as an evaluatee was included in the evaluator group, the results of this study showed that the percentage of entry submissions was higher compared to the contrary. Such results show that in the process of peer review–based research proposal evaluations for national R&D projects, alumni connections have significant influence on evaluation results in South Korea.

We review evidence for Macphail’s (1982, 1985, 1987) Null Hypothesis, that nonhumans animals do not differ either qualitatively or quantitatively in their cognitive capacities. Our review supports the Null Hypothesis in so much as there are no qualitative differences among nonhuman vertebrate animals, and any observed differences along the qualitative dimension can be attributed to failures to account for contextual variables. We argue species do differ quantitatively, however, and that the main difference in “intelligence” among animals lies in the degree (...) to which one must account for contextual variables. (shrink)

ABSTRACT In this paper we study consequence relations on the set of many sided sequents over a propositional language. We deal with the consequence relations axiomatized by the sequent calculi defined in [2] and associated with arbitrary finite algebras. These consequence relations are examples of what we call Gentzen systems. We define a semantics for these systems and prove a Strong Completeness Theorem, which is an extension of the Completeness Theorem for provable sequents stated in [2]. For the special case (...) of the finite linear MV-algebras, the Strong Completeness Theorem was proved in [10], as a consequence of McNaughton's Theorem. The main tool to prove this result for arbitrary algebras is the deduction-detachment theorem for Gentzen systems. (shrink)

Aunque es concebida como una asignatura eminentemente práctica, frecuentemente el especialista de música en Educación Primaria apoya su docencia en un libro de texto sobre el que sustenta gran parte de los contenidos musicales que ofrece al grupo. En ellos, pueden observarse una gran cantidad de ejercicios rítmicos, melódicos, audiciones, explicaciones teóricas y actividades para instrumentos o movimiento sobre los que articula su propia metodología. Entre ellos cabe destacar el uso que los libros de texto musicales hacen de las canciones (...) infantiles de procedencia histórica, folclórica o didácticas, empleadas para trabajar con diversos procedimientos. Ahora bien, ¿cuál es el papel de la identidad femenina dentro de esas canciones? ¿según su contenido textual, qué rol ocupa la mujer? ¿es apropiado para presentarlo en una sociedad dónde debe primar la igualdad de género? La presente propuesta analiza los estereotipos femeninos contenidos en las canciones infantiles de los libros de música de tres de las principales editoriales españolas: SM, Santillana y Anaya. A partir del estudio se podrán obtener conclusiones sobre el planteamiento y transmisión del modelo femenino que actualmente se está implantando en la escuela. (shrink)

En primer lugar, expondremos el trasfondo común que comparten las propuestas multiculturalistas y las intercultralistas, esto es, el particular énfasis que ponen en la necesidad de reconocimiento para la conformación de la personalidad y en las patologías que se derivan de la falta de reconocimiento. En segundo lugar, veremos algunos de los problemas que suscitan los planteamientos multiculturalistas: minorías dentro de las minorías, esencialismo y ausencia de cohesión social. En este punto también expondremos algunas de las propuestas del interculturalismo para (...) superar estos obstáculos. Por último, propondremos la noción de patriotismo constitucional como fórmula para la cohesión social, puesto que éste, al requerir una adhesión de tipo cívico, puede ser abrazado desde cualquier forma de vida particular, además de contemplar el importante papel de la sociedad civil a la hora de dar forma a sus principios a través del Derecho.In the first place, we will deal with the common background that multiculturalism and interclturalism share: the emphasis that they put in the necesity of recognition in the conformation of the personality and in the pathologies derived from the absence of recognition. In the second place, we will explore some of the problems that multiculturalism entails: minorities within minorities, essentialism and lack of social cohesion. At this point, we will explain some of the solutions that interculturalism has proposed for these problems. To conclude, we will propose the notion of constitutional patriotism as a means for achieving social cohesion. Constitutional patriotism demands some sort of civic engagement, so it can be supported from every particular cultural form of life. Besides, this proposal takes into account the important role of civic society when it comes to shape its principles through Law. (shrink)

This experimental paper proposes a shared exploration of the crease as a tactile, existential, and artistic phenomenon. It takes Roland Barthes’ definition of his left-handedness as “a tenuous and persistent crease” as a basis. Hence, this phenomenon is a minor but stubborn mark on the self, a superficial matter. In order to portray an intimate and personal approach to the subject, this paper is written in first person. This “I”, though, is plural, a result of a collaboration. As part of (...) the methodology developed to create this polyphonic voice, the paper is structured in a non-linear fashion. After each section, the reader can choose how to proceed. The imposed choices reveal the materiality of the text - they establish points of friction and awareness for a reader; and weave different discursive lines and surfaces. The aim is to allow the format to contribute to the definition of the crease, beyond images and excerpts in the content. (shrink)

RESUMEN: En este artículo se presenta la evaluación eudaimonista como una articulación entre el agente y los objetos del mundo. Sostendremos que, gracias a esta noción, la teoría de las emociones de Nussbaum es adecuada para dar cuenta de la función adaptativa de las emociones, por lo que las teorías no cognitivas no resultarían superiores en este aspecto. Esta noción serviría, asimismo, para no dejar de lado los aspectos cognitivos de la emoción. Veremos cómo las ideas de Nussbaum se basan (...) en las de las teorías evaluativas provenientes de la psicología, para después desplegar su propuesta en detalle. En la exposición, también trataremos otras cuestiones, entre ellas, la racionalidad de las emociones, la relación entre éstas y el florecimiento humano, o la vinculación de las mismas con nuestra condición vulnerable. ABSTRACT: This article presents eudaimonistic evaluation as an articulation between the agent and the objects of the world. We will argue that, thanks to this notion, Nussbaum's theory of emotions is appropriate to accounting for the adaptive function of emotions. This notion is useful for shedding light on the cognitive aspects of emotion. We will see how Nussbaum's ideas are based on evaluative theories from psychology, and we will explain in detail her proposals. In our explanation, we will deal with other questions such as the rationality of emotions, the relationship between emotions and human flourishing, and the link between emotions and our vulnerable nature.
