A common, yet diicult, task for people is planning satisfactory driving routes. Automatic systems for driving directions exist, but one of their major diiculties is the range of individual diierence regarding what constitutes a good route and a bad route. We introduce an adaptive user interface for route planning that uses relative feedback to model individual route preferences. Our experiments...

Ambient Intelligent (AmI) environments are supposed to act proactively anticipating the user’s needs and preferences, therefore the capability of an AmI system to learn those elements out of daily life behaviour of those using the environment is very valuable. In this paper we present a system that discovers patterns related to user’s actions and improves them through user feedback. The core of...

Using incentives to shape behavior requires that people understand the choice-outcome mapping and don’t use preferences or heuristics imported from other domains. We study an observable risk-return tradeoff for which risk preferences are normatively prescribed by a minimal assumption. The choice is whether to shoot a 2-pointer or a 3-pointer in professional (NBA) basketball. When losing, teams ...

We derive necessary and sufficient conditions in order for binary voting choices over a finite number of pairs of alternatives to be consistent with voter preferences that admit concave utility representations. These conditions imply simple testable restrictions on the location of voters’ ideal points, and can be used to predict individual voting behavior. On the other hand, if the location of ...

People’s choices can be predicted given information about their preferences. Learning people’s preferences is the inverse problem of inferring preferences from choices. Given the apparent relationship between choice prediction and preference learning, it is natural to ask whether the two are mutually consistent. Given weak assumptions, we show that no single, consistent model of the relationshi...

This paper studies differences in inequality perceptions, distributional norms, and redistributive preferences between East and West Germany. As expected, there are substantial differences with respect to all three of these measures. Surprisingly, however, differences in distributional norms are much smaller than differences with respect to inequality perceptions or redistributive preferences. ...

In allocating goods with no use of monetary transfers, random allocation mechanisms can be designed in order to elicit information on preference intensities. I study the nontransfer allocation of two ex-ante identical objects under Bayesian incentive compatibility, with symmetric agents and independent private valuations. I …nd the ex-ante utilitarian-optimal mechanism, in which the probability...

background & aim: healthcare areas, especially fertility care (commonly accompanied with high emotions, as well as long-term and recurring treatment periods) could exclusively benefit from patient-centered care (pcc). despite evident advantages of pcc, this approach has not been practiced as a routine procedure in current clinical environments yet, even in western developed countries. therefore...

BACKGROUND Non-specific chronic low back pain (NSCLBP) has become a significant problem due to high healthcare utilization, rising costs of care and perceived limitations of effectiveness of many current treatments. Systematic reviews have repeatedly concluded that, on average across participants, exercise for NSCLBP appears effective in decreasing pain and improving function. Not all people wi...
