In 2007, Abdulla et al. introduced the concept of decisiveness, an interesting tool for lifting good properties finite Markov chains to denumerable ones. Later, this was extended more general stochastic transition systems (STSs), allowing design various verification algorithms large classes (infinite) STSs. We further improve understanding and utility decisiveness in two ways. First, we provide...

When rationality is bounded, a variety of factors may influence how far a choice is from optimal. We examine the willingness to search among alternatives. We find fixed individual differences in this temperament measure. People may be usefully typed according to how they obtain improved choices. More patient subjects obtain improvement by effectively using decision resources, performing better ...

We investigate implementation of social choice functions as mappings from states to lotteries under complete information. We assume that for every agent, any pair of distinct states induces distinct preferences. A social choice function is called Condorcet-decisive if it always enforces the Condorcet winner among its range. We introduce plurality mechanisms, where each agent makes a single anno...

We show that simple majority rule satisfies five standard and attractive axioms—the Pareto property, anonymity, neutrality, independence of irrelevant alternatives, and (generic) decisiveness—over a larger class of preference domains than (essentially) any other voting rule. Hence, in this sense, it is the most robust voting rule. This characterization of majority rule provides an alternative t...

INTRODUCTION AND PURPOSE Academic anxiety is an important educational problem that affects millions of students in colleges and schools over the world each year. Although a low level of anxiety can cause positive motivation for improvement of educational functioning, high levels of it can cause a disturbance in concentration, attention, storage of knowledge, recall and educational reduction. It...

We examined three parallel data sets with respect to qualities relevant to phylogenetic analysis of 20 exemplar monocotyledons and related dicotyledons. The three data sets represent restriction-site variation in the inverted repeat region of the chloroplast genome, and nucleotide sequence variation in the chloroplast-encoded gene rbcL and in the mitochondrion-encoded gene atpA, the latter of w...

We apply classical quartet techniques to the problem of phylogenetic decisiveness and find a value k such that all collections of at least k quartets are decisive. Moreover, we prove that this bound is optimal and give a lower-bound on the probability that a collection of quartets is decisive.
