The possibility to interpret expected and nonexpected utility theories in purely probabilistic terms has been recently investigated. Such interpretation proposes as guideline for the Decision Maker the comparison of random variables through their probability to outperform a stochastic benchmark. We apply this type of analysis to the model of Becker and Sarin, showing that their utility functional may be seen as the probability that an opportune random variable, depending on the one to be evaluated, does not outperform a non-random benchmark. (...) Further, the consequent choice criterion is equivalent to a sort of probability of ruin. Possible interpretations and financial examples are discussed. (shrink)

In recent years, the contribution of various disciplines and professionals (i.e. from marketing, computer science, psychology and pedagogy) to museum management has encouraged the development of a new conception of museology. Specifically, psychology has affected the overall conception of museum and the visitors towards a more holistic vision of the museum experience as a complexity of memory, personal drives, group identity, meaning-making process, as well as leisure preferences. In this regard, psychological research contributes to advance the scientific knowledge about psychological (...) and social phenomena related to the visitor experience, as well as to design innovative technologies and future tourism services. The present contribution discusses the Socio-Cultural Activity Theory as a theoretical framework to conceptualize the museum visit as an activity mediated by the technology, and to better identify the factors shaping the interaction between the visitors and the technologies. To do so, a case study is presented: a qualitative research performed at the Ara Pacis Museum in Rome (Italy) to analyze the visitor experience of a tour that integrates augmented and virtual reality. Information derived from applying Activity Theory on visitors’ experience highlight the value of technology as mediating tool between the museum mission and the visitor experience, considering the interaction between visitors’ characteristics, museum environmental dimensions and technology’s features.
