Non-locality of the phenomenon of consciousness according to Roger Penrose
Roger Penrose is known for his proposals, in collaboration with Stuart Hameroff, for quantum action in the brain. These proposals, which are still recent, have a prior, less known basis, which will be studied in the following work. First, the paper situates the framework from which a mathematical physicist like Penrose proposes to speak about consciousness. Then it shows how he understands the possible relationships between computation and consciousness and what criticism from other authors he endorses, to conclude by explaining how he understands this relationship between consciousness and computation. Then, it focuses on the concept of non-locality so essential to his understanding of consciousness. With some examples, such as impossible objects or aperiodic tiling, the study addresses the concept of non-locality as Penrose understands it, and then shows how far he intends to arrive with that concept of non-locality. At all times the approach will be more philosophical than physical
On bayesian robustness: an asymptotic approach
This paper presents a new asymptotic approach to study the robustness of Bayesian inference to changes on the prior distribution. We study the robustness of the posterior density score function when the uncertainty about the prior distribution has been restated as a problem of uncertainty about the model parametrization. Classical robustness tools, such as the influence function and the maximum bias function, are defined for uniparametric models and calculated for the location case. Possible extensions to other models are also briefly discussed
Dreams in Evagrius Ponticus' Life and teaching
There are few late antiquity authors who pay more attention than Evagrius todreams. For him, visions and dreams are not a way to prophesy the future or tokeep in contact with the dead. They are basically a way to know oneself and thestate of ones own spiritual life. After contextualizing the theories on dreams in themost significant authors of that period, I discuss the place that visions and dreamsoccupied in the Evagrian corpus, describing their mechanisms as a complex operationbetween passions, memory and the influence of demons.Fil: Peretó Rivas, Rubén Angel.
