In this contribution, we use the connection between stable polynomials and orthogonal polynomials on the real line to construct sequences of Hurwitz polynomials that are robustly stable in terms of several uncertain parameters. These sequences are constructed by using properties of orthogonal polynomials, such as the well-known three-term recurrence relation, as well as by considering linear combinations of two orthogonal polynomials with consecutive degree. Some examples are presented.

Structured argumentation systems, and their implementation, represent an important research subject in the area of Knowledge Representation and Reasoning. Structured argumentation advances over abstract argumentation frameworks by providing the internal construction of the arguments that are usually defined by a set of (strict and defeasible) rules. By considering the structure of arguments, it becomes possible to analyze reasons for and against a conclusion, and the warrant status of such a claim in the context of a knowledge base represents the main (...) output of a dialectical process. Computing such statuses is a costly process, and any update to the knowledge base could potentially have a huge impact if done naively. In this work, we investigate the case of updates consisting of both additions and removals of pieces of knowledge in the Defeasible Logic Programming (DeLP) framework, first analyzing the complexity of the problem and then identifying conditions under which we can avoid unnecessary computations—central to this is the development of structures (e.g. graphs) to keep track of which results can potentially be affected by a given update. We introduce a technique for the incremental computation of the warrant statuses of conclusions in DeLP knowledge bases that evolve due to the application of (sets of) updates. We present the results of a thorough experimental evaluation showing that our incremental approach yields significantly faster running times in practice, as well as overall fewer recomputations, even in the case of sets of updates performed simultaneously.

Relying on some auxiliary assumptions, usually considered mild, Bell’s theorem proves that no local theory can reproduce all the predictions of quantum mechanics. In this work, we introduce a fully local, superdeterministic model that by explicitly violating ‘settings independence’—one of these auxiliary assumptions, requiring statistical independence between measurement settings and systems to be measured—is able to reproduce all the predictions of quantum mechanics. Moreover, we show that contrary to widespread expectations, our model can break settings independence without an initial state (...) that is too complex to handle, without visibly losing all explanatory power, and without outright nullifying all of experimental science. Still, we argue that our model is unnecessarily complicated and does not offer true advantages over its non-local competitors. We conclude that while our model does not appear to be a viable contender to its non-local counterparts, it provides the ideal framework to advance the debate over violations of statistical independence via the superdeterministic route.

Neoclassical economics assumes that individuals have stable and context-independent preferences, and uses preference satisfaction as a normative criterion. By calling this assumption into question, behavioural findings cause fundamental problems for normative economics. A common response to these problems is to treat deviations from conventional rational choice theory as mistakes, and to try to reconstruct the preferences that individuals would have acted on, had they reasoned correctly. We argue that this preference purification approach implicitly uses a dualistic model of the human (...) being, in which an inner rational agent is trapped in an outer psychological shell. This model is psychologically and philosophically problematic. (shrink)

El siguiente texto se circunscribe en el ámbito de la filosofía de la religión; tiene como objeto central analizar la alienación del hombre dentro del fenómeno religioso (particularmente en las religiones monoteístas) y cómo esta origina intolerancia social en las sociedad contemporáneas entre hombres que no comparten las mismas creencias; esta postura ha causado momentos de violencia extrema a lo largo de la historia humana y otra tanta en la actualidad como el conflicto en el Medio Oriente – Judíos y (...) Musulmanes. Para tal empresa tomaremos como referencia la crítica a la religión expuesta por el pensador alemán del siglo XIX Ludwig Feuerbach en su obra principal: La esencia del cristianismo (Das Wesen des Christentums), complementándolo con otros críticos religiosos (Voltaire, Kirsch, Freud, etc.). Por último, expondremos el ateísmo humanista de Feuerbach como alternativa para la superación de la intolerancia social. (shrink)

This note replies to a comment by Daniel Hausman on our paper ‘Preference purification and the inner rational agent: a critique of the conventional wisdom of behavioural welfare economics’. We clarify our characterisation of behavioural welfare economics and acknowledge that Hausman does fully endorse this approach. However, we argue that Hausman’s response to our critique, like behavioural welfare economics itself, implicitly uses a model of an inner rational agent.

A central debate in the current philosophical literature on temporal experience is over the following question: do temporal experiences themselves have a temporal structure that mirrors their temporal contents? Extensionalists argue that experiences do have a temporal structure that mirrors their temporal contents. Atomists insist that experiences don’t have a temporal structure that mirrors their contents. In this paper, I argue that this debate is misguided. Both atomism and extensionalism, considered as general theories of temporal experience, are false, since temporal (...) experience is not a single undifferentiated phenomena as both theories require. I argue for this conclusion in two steps. First, I show that introspection cannot settle the debate. Second, I argue that the neuroscientific evidence is best read as revealing a host of mechanisms involved in temporal perception - some admitting of an extensionalist interpretation while others admitting only of an atomistic interpretation. As a result, neither side of the debate wins. (shrink)

We argue that animals are not cognitively stuck in time. Evidence pertaining to multisensory temporal order perception strongly suggests that animals can represent at least some temporal relations of perceived events.

A partir de los conceptos de carácter, virtud y amistad propuestos por la ética de la ficción de Wayne Booth, realizamos un análisis comparativo entre los efectos éticos provocados por el territorio y la música en las novelas Península, Península de Hernán Lara Zavala y en El llamado de los tunk’ules de Marisol Ceh Moo. Sugerimos que, a pesar de estar ante dos novelas que comparten el mismo contexto geo-histórico, los efectos éticos causados por el territorio y la música, bajo (...) la idea de Yucatán, guardan diferencias que ameritan llevar a cabo una co- ducción para dilucidar el tipo de compañía literaria que nos ofrecen.

While we perceive events in our environment through multiple sensory systems, we nevertheless perceive all of these events as occupying a single unified timeline. Time, as we perceive it, is unified. I argue that existing accounts of the perceived unity of time fail. Instead, the perceived unity of time must be constructed by integrating our initially fragmented timekeeping capacities. However, existing accounts of multimodal integration do not tell us how this might occur. Something new is needed. I finish the paper (...) by articulating the hurdles that must be overcome to provide an account of the perceived unity of time. (shrink)

It’s often claimed in the philosophical and scientific literature on temporal representation that there is no such thing as a genuine sensory system for time. In this paper, I argue for the opposite—many animals, including all mammals, possess a genuine sensory system for time based in the circadian system. In arguing for this conclusion, I develop a semantics and meta-semantics for explaining how the endogenous rhythms of the circadian system provide organisms with a direct information link to the temporal structure (...) of their environment. In doing so, I highlight the role of sensory systems in an information processing architecture. (shrink)

Memories often come with a feeling of pastness. The events we remember strike us as having occurred in our past. What accounts for this feeling of pastness? In his recent book, Memory: A self-referential account, Jordi Fernández argues that the feeling of pastness cannot be grounded in an explicit representation of the pastness of the remembered event. Instead, he argues that the feeling of pastness is grounded in the self-referential causal content of memory. In this paper, I argue that this (...) account falls short. The representation of causal origin does not by itself ground a feeling of pastness. Instead, I argue that we can salvage the temporal localization account of the feeling of pastness by describing a form of egocentric temporal representation that avoids Fernández’s criticisms.

Various writers have attempted to use the sender-receiver formalism to account for the representational capacities of biological systems. This paper has two goals. First, I argue that the sender-receiver approach to representation cannot be complete. The mammalian circadian system represents the time of day, yet it does not control circadian behaviours by producing signals with time of day content. Informative signalling need not be the basis of our most basic representational capacities. Second, I argue that representational capacities are primarily about (...) control, and only when specific conditions obtain does this control require informative signalling. (shrink)

En la actual campaña electoral uruguaya de 2019, se perfila un cuadro de descontentos generalizados que desborda claramente los estándares tradicionales de la política del país. Muchos de estos descontentos se articulan con diversos factores que los autores han venido destacando en trabajos anteriores, como señales de una mutación gradual pero efectiva de la política uruguaya. En continuidad con ese abordaje de investigación, en el artículo se indagará acerca de las posibilidades efectivas de que esta mutación política adquiera proporciones realmente (...) significativas en las actuales circunstancias, con la posibilidad de confirmación de "cisnes negros" que parecen atisbarse en la campaña electoral en curso. Para ello, luego de algunos discernimientos teóricos y metodológicos, se trabajará el itinerario de distintos indicadores de opinión pública a nivel nacional durante el período 1995-2017, vinculados con el objeto de estudio planteado. A partir de esos insumos, se realizarán algunas breves consideraciones de proyección analítica. (shrink)

Chile’s recent history has gone through a hybrid conjuncture between what has been called the “social outbreak” on October 18, 2019, and the declaration of health emergency by COVID-19 promulgated on March 18, 2020. In such a context, this article describes and interprets two presidential speeches that announce the States of Exception based on conjunctural enemies’ rise. This social problem is investigated from Critical Discourse Studies and Systemic Functional Linguistics, particularly the appraisal system, together with the categories of legitimation proposed (...) by van Leeuwen. This research is positioned from a qualitative perspective and takes as a corpus of analysis the two speeches declaring a State of Exception by President Piñera in 2019 and 2020, respectively. These speeches are available to the public at https://prensa.presidencia.cl/. The results show that an enemy is constructed in both cases by contrasting the actions taken or not, which present negative appreciation valuations in the case of COVID-19 and negative integrity judgments in the case of the social outbreak. In both cases, key social actors emerge that are firmly legitimized within the State of Exception framework, which in turn is based on the categories of authority and moral legitimation. In conclusion, the enemy’s construction is identified in both cases with modification of the actors that interact through a problem, an action, and an agent that solves the problem constructed.
