Frequent patterns are an important class of regularities that exist in a database. Although there exists no universally acceptable best measure to assess the interestingness of a pattern, relative support is emerging as a popular measure to discover frequent patterns involving both frequent and rare items. An Apriori-like algorithm known as Relative Support Apriori (RSA) has been discussed in t...

We identify in this paper two conditions that characterize the domain of single-peaked preferences on the line in the following sense: a preference profile satisfies these two properties if and only if there exists a linear order L over the set of alternatives such that these preferences are single-peaked with respect L. The first property states that for any subset of alternatives the set of a...

The additivity number of a topological property (relative to a given space) is the minimal number of subspaces with this property whose union does not have the property. The most well-known case is where this number is greater than א0, i.e. the property is σ-additive. We give a rather complete survey of the known results about the additivity numbers of a variety of topological covering properti...

In the 1960s many American cities experienced violent, race-related civil disturbances. This article examines census data from 1950 to 1980 to measure the riots’ impact on the value of central-city residential property, and especially on black-owned property. Both OLS and IV estimates indicate that the riots depressed the median value of black-owned property between 1960 and 1970, with little o...
