Este ensayo ilustra relaciones entre educación, comunicación y complejidad. Se vinculan para complejizar lo que parece sencillo: la comunicación educativa. Su finalidad es mostrar tensiones al comunicar. Enlaza educar y comunicar apoyándose en propuestas de la teoría de la complejidad: códigos, incertidumbre y relatividad. La postura metodológica reúne métodos: fenomenológico-descriptivo, hermenéutico-explicativo, pedagógico-prescriptivo; no los explicita. Primero, describe la tendencia de circunscribir el trabajo universitario al aprendizaje estudiantil; se ilustra para contrastarla con ciencias de la educación adicionales a la psicología. Luego (...) se narra la complejidad de la comunicación docente al humanizar: educar, socializar y jugar. Después se muestra la importancia de justipreciar la comunicación educativa compleja. Complejidad enmarcada en la crisis del paradigma actual. Ulteriormente, ese paradigma se detalla con el recurso de los códigos ideológico, cultural, particular, individual, pedagógico y disciplinar. Se concluye reconociendo la urgencia de humildad, soberbia y eros docente para humanizar(se), conforme a una comunicación educativa compleja. (shrink)

We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...) to the problem of outcomes in quantum measurement by providing a sharp criterion for defining when an event has taken place. We analyze in detail in examples two situations in which in principle one could recover information about quantum coherence: a) “revivals” of coherence in the interaction of a system with the measurement apparatus and the environment and b) the measurement of global observables of the system plus apparatus plus environment. We show in the examples that the fundamental limitations due to gravity and quantum mechanics in measurement prevent both revivals from occurring and the measurement of global observables. It can therefore be argued that the emerging picture provides a complete resolution to the measurement problem in quantum mechanics. (shrink)

We make a first attempt to axiomatically formulate the Montevideo interpretation of quantum mechanics. In this interpretation environmental decoherence is supplemented with loss of coherence due to the use of realistic clocks to measure time to solve the measurement problem. The resulting formulation is framed entirely in terms of quantum objects without having to invoke the existence of measurable classical quantities like the time in ordinary quantum mechanics. The formulation eliminates any privileged role to the measurement process giving an objective (...) definition of when an event occurs in a system. (shrink)

It is well-known that adding to a lattice the usual relative meet complement is not conservative, in the sense that distributivity is implied. In this paper we consider a weak relative meet complement that does not have the mentioned effect. We mostly study the mentioned operation from an algebraic point of view. However, we also provide a Hilbert-style axiomatization for its corresponding assertional logic.

There is growing worldwide concern that the rampant spread of digital fake news via new media technologies is detrimentally impacting Democratic elections. However, the actual influence of this recent Internet phenomenon on electoral decisions has not been directly examined. Accordingly, this study tested the effects of attention to DFN on readers’ Presidential candidate preferences via an experimental web-survey administered to a cross-sectional American sample. Results showed no main effect of exposure to DFN on participants’ candidate evaluations or vote choice. However, (...) the perceived believability of DFN about the Democratic candidate negatively mediated evaluations of that candidate—especially amongst far-right ideologues. These results suggest that DFN may at worst reinforce the partisan dispositions of mostly politically conservative Internet users, but does not cause or induce conversions in these dispositions. Overall, this study contributes novel experimental evidence, indicating that the potential electoral impact of DFN, although concerning, is strongly conditional on a reciprocal interaction between message receptibility and a pre-existing right-wing ideological orientation. The said impact is, therefore, likely narrow in scope. (shrink)

Disconcerting findings from nascent sociological research suggest that Western youth are developing subjectivities that reflect neoliberal discursive formations of self-interest, competitiveness, and materialism. However, propositions about: (1) the cognitive-affective mechanisms that explain how youth acquire and reproduce neoliberal ideology, or (2) the dispositions and behaviours that typify a neoliberal subject, remain vague. Therefore, this article provides a novel conceptualization of these two psychosocial facets that can help advance understandings and investigations of the emerging modes and societal consequences of neoliberal subjectification, (...) Specifically, it reviews major theoretical tenets from the respective literatures on neurocognitive development, social cognition, neoliberalism, and neoliberal hegemony. It then synthesizes these tenets within a modified habitus formulation to sketch a testable cognitive-sociological model to explain and explore some of the distinct dispositional values, attitudes, and practices that youth raised in societies with institutionally and culturally prevalent neoliberal norms and discourses potentially may develop and enact.

The mortality rate of patients affected with oral squamous cell carcinoma has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes (...) in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnostic delay ranging from 45 days to approximately 6 months. Patients’ fears and, to a lesser degree, the concerns of dentists, were found to be still poorly investigated. On the basis of the authors’ professional experience, the development of oral lesions of unknown origin may generate different behaviors in the decision-making processes by patients and clinicians, and fear may play a key role in the distinct steps of this process. It is crucial to increase awareness and inform patients about the onset of OSCC, and contemporaneously encourage experimental studies on patients’ fear and professional behaviors with respect to communication regarding OSCC.

The idea of a probabilistic logic of inductive inference based on some form of the principle of indifference has always retained a powerful appeal. However, up to now all modifications of the principle failed. In this paper, a new formulation of such a principle is provided that avoids generating paradoxes and inconsistencies. Because of these results, the thesis that probabilities cannot be logical quantities, determined in an objective way through some form of the principle of indifference, is no longer supportable. (...) Later, the paper investigates some implications of the new principle of indifference. To conclude, a re-examination of the foundations of the so-called objective Bayesian inference is called for. (shrink)

En este trabajo realizo un examen crítico del reciente libro de Silvana Gabriela Di Camillo sobre la crítica de Aristóteles a la teoría platónica de las Ideas. El libro de Di Camillo es un trabajo muy serio cuya lectura recomiendo ampliamente. Sin embargo, considero que cuatro de las principales tesis que la autora defiende tienen varias dificultades y mi objetivo aquí es presentar argumentos detallados en contra de ellas: la interpretación de la distinción entre argumentos más y menos rigurosos del (...) tratado Sobre las Ideas; la tesis de que la separación es el blanco esencial de las críticas aristotélicas a las Ideas; la interpretación de las opciones que Platón tiene para responder al argumento del tercer hombre, y la tesis de que la separación de las Ideas debe entenderse como homonimia. In this paper I examine Silvana Gabriela Di Camillo's recent book on Aristotle's criticisms of Plato's theory of Ideas. Di Camillo's book is a very serious work that I highly recommend. Nevertheless, I consider that four of the main theses that the author defends face several difficulties and my aim here is to offer detailed arguments against them: the interpretation of the distinction between more and less accurate arguments of the treatise On Ideas; the thesis that separation is the essential target of Aristotle's criticisms against Plato's Ideas; the interpretation of the options available to Plato to reply to the third man argument; and the thesis that the separation of Ideas should be understood as homonymy.

Populist representation is the process by which a body or set of bodies become the signifier of a powerful act of political transgression of the social order. We call this specific type of representative linkage ‘synecdochal representation’. In it, the leader’s body performs three key functions: it mirrors certain popular traits that are characterized as ‘low’, it displays marks of exceptionality, and it appropriates symbols of institutional power. These tasks are performed through particular ways of acting, dressing, talking, eating, and (...) the like, in public. Social media has become a key locus for bodily self-presentation because it is used to create the appearance of intimacy and spontaneity through the distribution of ‘candid’ pictures and videos. This paper will analyze how the self-presentation of populist and non-populist leaders are established through Twitter, what images they choose to disseminate, and how they are re-signified by the audience. To do so, we will focus on the two Latin American politicians: Cristina Fernández (with a populist style) and Mauricio Macri (with a technocratic one). (shrink)

Habermas ha elaborado una teoría jurídica a partir de su filosofía de acción comunicativa. Sin alejarse de los fundamentos tradicionales que sustentan al Estado democrático de derecho, ha innovado una posición de legitimación al derecho y a su ejercicio, incluso ofrece nuevas herramientas conceptuales para la función judicial, como es el caso de lo que podría llamarse la adecuación que sustituye a la conocida propuesta de la ponderación de los derechos. El presente artículo pretende servir de guía para adentrase en (...) el territorio de su propuesta. (shrink)
