Communication in social insects and how it is shaped by individual experience
2019
Communication is the foundation of all social systems, and learning is perhaps the most important cognitive tool. But how do these two critical faculties interact? With social insects being some of the best learners of the invertebrate world, and indisputably the most communicative, we examine the role of learning and experience in social insect communication. Learning plays a major role for both senders and receivers. A sender's experience can modulate what information is available for communication, whether communication is effective and whether individuals are motivated to communicate. Signalling about a resource is often modulated relative to the value of that resource and relative to t…
COVID–19. Effect of Moral Messages to Persuade the Population to Stay at Home in Spain, Chile, and Colombia
2021
1.362 / 5.000 Resultados de traducción Analizar si el contenido de tres mensajes morales (deontológico, utilitarismo ético, virtud ética) y un mensaje de control afectan diferencialmente la probabilidad de realizar cuatro comportamientos: lavarse las manos, participar en reuniones públicas, quedarse en casa/evitar el contacto social y reenviar el mensaje para informar a más personas. En nuestro estudio, el emisor del mensaje es un profesor universitario. Estas variables se miden en términos de sus intenciones de comportamiento y las intenciones de comportamiento de los demás (creencias sobre el comportamiento de los demás). Ensayo controlado aleatorizado. Nuestro estudio incluye el análisis…
Pragmatic languages with universal grammars
2012
Abstract This paper constructs the equilibrium for a specific code that can be seen as a “universal grammar” in a class of common interest Sender–Receiver games where players communicate through a noisy channel. We propose a Senderʼs signaling strategy which does not depend on either the game payoffs or the initial probability distribution. The Receiverʼs strategy partitions the set of possible sequences into subsets, with a single action assignment to each of them. The Senderʼs signaling strategy is a Nash equilibrium, i.e. when the Receiver responds best to the Senderʼs strategy, the Sender has no incentive to deviate. An example shows that a tie-breaking decoding is crucial for the block…
An asynchronous covert channel using spam
2012
AbstractCurrent Internet e-mail facilities are built onto the foundation of standard rules and protocols, which usually allow a considerable amount of “freedom” to their designers. Each of these standards has been defined based on a number of vendor specific implementations, in order to provide common inter-working procedures for cross-vendor communication. Thus, a lot of optional and redundant information is being exchanged during e-mail sessions, which is available to implement versatile covert channel mechanisms.This work exploits this possibility by presenting a simple but effective steganographic scheme that can be used to deploy robust secret communication through spam e-mails. This s…
Mirando la esfera de las horas: literatura, tiempo y antifascismo en el Bienio Negro
2019
This text attempts to be an invitation to think about a temporal experience that claims to be historically thought in order to articulate the resistance against fascism. First of all, I will introduce the discussion of the definition of the republican project, by studying the implications of the term it applied to itself: revolution. With this, I will introduce Ehrenburg’s view of the tensions of the time as a temporary pathology. Later, I will outline the antifascist political culture through the magazines Linea and Nueva Cultura. Then, I will approach Historia de un dia (Sender et al., 1935) and explain the link between the representations of time and the people. Afterwards, I will procee…
Entre la gramática y el discurso: reformuladores alemanes en proceso de fijación
2015
This paper aims, on the one hand, to critically revise the notion of reformulation from the perspective of the Operator-Scopus-Theory and its understanding of discourse based on the interpretative capacity of the recipient and the sender’s attempt to adjust his linguistic production to the expectations of this recipient in order to attain a specific end. On the other hand, we will analyse three reformulation markers which have been scarcely dealt with in the specialised bibliography, since they can render evidence on the defining features of the category and on the transition of these markers (still uncompleted in many of them) towards their full conversion into invariable particles with ty…
Vacuum Suppression in Gain-tuned Continuous-Variable Quantum Teleportation of a Single Photon by Conditioning on Sender
2014
We experimentally demonstrate bolstering the strength of gain-tuned continuous variable quantum teleportation of a single photon by conditioning on the sender's measurement results to eliminate excess vacuum contamination in the output.
No place for negative emotions? The effects of message valence, communication channel, and social distance on users’ willingness to respond to SNS st…
2017
Abstract The present study contributes to the investigation of communicative norms and social support in Social Network Sites (SNSs). We suggest that a positivity bias restricts the availability of social support users receive from others via public responses to negative status updates. Moderated mediation analyses of the data of an online experiment ( N = 870, M age = 25.16 years, 64% female) show that users are less willing to comment on negative status updates than on positive ones. In contrast, users are more willing to respond to negative status updates with private messages. These effects are moderated by the strength of the relationship between sender and receiver of the status upd…
Letters in Arabic sent from the Nasrid Court. A diplomatic analysis
2018
El trabajo aplica las técnicas de la ciencia Diplomática a la correspondencia enviada desde la corte nazarí de Granada a monarcas y señores de los reinos de Aragón y Castilla. Por razones de coherencia y espacio, se centra únicamente en las misivas redactadas en árabe. El objetivo es establecer sus caracteres extrínsecos (tamaño y color del papel, tipo de letra, características del sello, presencia o no deʽalāma) e intrínsecos (manera de dirigirse al destinatario, manera de presentarse, saludos, tipo de datación tópica y crónica), comprobar si con el paso del tiempo hubo evolución en las fórmulas y si se refleja en éstas la categoría social de remitente y destinatario. Las fuentes empleadas…
El componente pragmático en los diccionarios: Implicaciones para la Lexicografía
2015
Dictionaries are a list of words, simple or complex, that are treated as entries (lexical items). It is usual to assert several components: the lemma or headword, named after its most neutral form, followed by an indication of the main inflections of its category: genre and number if they are names, syntactic class if they are verbs. Sometimes, indications of it are made in other aspects: etymology, pronunciation, marks of placement, area of use, register, frequency of use, etc.Among all the group, it is pointed out an area that grows daily, painstakingly, in lexicographic works: the pragmatic component. Most of the words are referential (names, verbs, adverbs), but others correspond to lan…
