We consider cheap talk by a biased expert comparing multiple issues, e.g., discussion of different spending proposals by an industry lobbyist, evaluation of different stocks by a sell-side analyst, or analysis of different topics by a biased newspaper. When the expert’s motives are sufficiently transparent, we find that cheap talk is credible and influential even when the expert strongly favors...

In this paper, we introduce a notion of epistemic equivalence between hierarchies of conditional beliefs and hierarchies of lexicographic beliefs, thus extending the standard equivalence results of Halpern (2010) and Brandenburger et al. (2007) to an interactive setting, and we show that there is a Borel surjective function, mapping each conditional belief hierarchy to its epistemically equival...

We study the problem of elicitation of subjective beliefs of an agent when the beliefs are ambiguous (the set of beliefs is a non-singleton set) and the agent’s preference exhibits ambiguity aversion; in particular, as represented by α-maxmin preferences. We construct a direct revelation mechanism such that truthful reporting of beliefs is the agent’s unique best response. The mechanism uses kn...

This paper examines the nature of partisan preferences on a range of issue scales. It compares preferences in a period of strong ideological focus, in the late eighties and early nineties, with preferences in 2000 and 2001 – a period of weak ideological focus. Where partisan preferences were formerly polarised, they are now more consensual. I argue that once positional issues now resemble valen...

If students are demotivated, confused and look tired in class, one solution is to use new teaching styles in your class to overcome such problems. This is because learners learn in different ways such as hearing, seeing, taking notes, imagining and visualizing, among many others. The paper reports firstly, the impact of teaching and learning style preferences and their match or mismatch on lear...

This paper provides information about the standards that govern accessibility of learning objects, presents an example of an accessible learning object and shows the procedure to operate the Moodle learning platform which has been adapted by the authors to the preferences and needs of the students. The way to operate the Moodle adapted platform takes place in three phases. In the first phase, t...

This paper presents a machine-learning approach to modeling human behavior in one-shot games. It provides a framework for representing and reasoning about the social factors that affect people’s play. The model predicts how a human player is likely to react to different actions of another player, and these predictions are used to determine the best possible strategy for that player. Data collec...

Product and content personalization is now ubiquitous in e-commerce. There is typically too little available transactional data for this task. As such, companies today seek to use a variety of information on the interactions between a product and a customer to drive personalization decisions. We formalize this problem as one of recovering a large-scale matrix, with side information in the form ...

E-learning usability is a goal of the user centred e-learning design. Its achievement depends on the determination of the requirements and preferences of the users of an e-learning system or environment (learner, teacher and administrator of an educational process). This paper presents an approach to estimation of learner’s preferences that have to influence the teaching process in the creation...

Personality and individual differences are effective parameters in human activities such as learning. Since the learning style of each learner is different, we must fit learning to the different needs of learners. In this paper, an innovative learning approach is proposed by considering the learner’s preferences. Using the Myers-Briggs Type Indicator’s (MBTI) tools, a framework for adaptive tea...
