We study the manner in which learning shapes behavior towards risk when individuals are not assumed to know, or to have beliefs about, probability distributions. In any period, the behavior change induced by learning is assumed to depend on the action chosen and the payoff obtained. We characterize learning processes that, in expected value, increase the(More)
MRP1 transporter correlates positively with glioma malignancy and the Multiple Drug Resistance (MDR) phenotype in Glioblastoma Multiforme (GBM). Evidence shows that the MRP1 transporter is controlled by the adenosine signalling axis. The aim of this study was to identify the role of adenosine on the MDR phenotype in Glioblastoma Stem-like Cells (GSCs), the(More)
The most aggressive type of brain tumor is glioblastoma multiforme, which to date remains incurable. Thuja occidentalis is used in homeopathy for the treatment of cancer, however, its mechanism of action remains unknown. We set out to study the effects of thujone fractions of Thuja on glioblastoma using in vitro and in vivo models. We found that the α/(More)
Altered nucleoside levels may be linked to pathogenic signaling through adenosine receptors. We hypothesized that adenosine dysregulation contributes to fibrosis in diabetic kidney disease. Our findings indicate that high glucose levels and experimental diabetes decreased uptake activity through the equilibrative nucleoside transporter 1 (ENT1) in proximal(More)
We provide a general framework to study stochastic sequences related to individual learning in economics, learning automata in computer sciences, social learning in marketing, and other applications. More precisely, we study the asymptotic properties of a class of stochastic sequences that take values in [0, 1] and satisfy a property called " bounded(More)
Ecosystem management is a conservation strategy, but there is not a standard protocol for implementation. In theory, ecosystem management will utilize the best available science to sustain social-ecological systems in the landscape by maximizing multiple ecosystem services expected from the stakeholders’ of those systems. Llancahue is a watershed (1,270 ha)(More)
Decision makers are often described as seeking higher expected payo¤s and avoiding higher variance in payo¤s. We provide some necessary and some su¢ cient conditions for learning rules, that assume the agent has little prior and feedback information about the environment , to re ‡ect such preferences. We adopt the framework of Börgers, Morales and Sarin(More)
We study strategic communication in some variations of the sender-receiver game where an uninformed receiver chooses an object on recommendations from many informed senders whose incentives are unknown to the receiver. In a game where some senders always truthfully report object's quality and some are biased senders who communicate strategically, we find(More)
