In this paper I compare two different the models of two-dimensional belief change, namely ‘revision by comparison’ (Fermé and Rott, Artificial Intelligence 157, 2004) and ‘bounded revision’ (Rott, in Hommage à Wlodek, Uppsala 2007). These revision operations are two-dimensional in the sense that they take as arguments pairs consisting of an input sentence and a reference sentence. Two-dimension...

We present a decision-theoretically motivated notion of contraction which, we claim, encodes the principles of minimal change and entrenchment. Contraction is seen as an operation whose goal is to minimize loses of informational value. The operation is also compatible with the principle that in contracting A one should preserve the sentences better entrenched than A (when the belief set contain...

Fermé and Rott (‘Revision by Comparison’, Artificial Intelligence 157, 2004) introduced a binary operation of ‘revision by comparison’ and pointed out that this method of changing epistemic states has both characteristics of belief contraction (with respect to the ‘reference sentence’) and characteristics of belief revision (with respect to the ‘input sentence’). Using revision by comparison as...

A dominant concern in rational choice theory is rationalizability of choice functions. Rationalizability demands that a choice function can be represented by a preference relation according to which the choice function selects for each decision problem those alternatives which are most preferred (or undominated by other alternatives). A less demanding notion demands that a choice function can b...

This unprecedented research endeavors to investigate the relationship between dark personality traits (i.e., narcissism, Machiavellianism, and psychopathy) and corruption intention through the mediation of anxiety.  Based on the resource conservation theory, it is hypothesized that those higher in dark personality traits are more inclined to corrupt when they feel anxious. Having collected data...

In this paper, we propose a scheme of rate control for continuous UDP ow with moderate fairness. First, per-packet Relative One-way Trip Time (ROTT) of a UDP stream at a receiver on the Internet is investigated extensively, and it is found that spikes with successive plots, which we call spike-trains, often appear on a time-ROTT graph. Also, congestion-related losses are found to be strongly co...
