BACKGROUND This paper describes a pilot survey of faculty involved in medical education. The questionnaire focuses on their understanding of IRB policies at their institution, specifically in relation to the use of student assessment and curriculum evaluation information for scholarship. METHODS An anonymous survey was distributed to medical educators in a variety of venues. Two brief scenari...

One of the main shortcomings of traditional methods for combining theories is the complexity of guessing the arrangement of variables shared by the individual theories. This paper presents a reformulation of the Nelson-Oppen method that takes into account explicit equality propagation and can ignore pairs of shared variables that the theories do not care about. We show the correctness of the ne...

In many domains, we are interested in analyzing the structure of the underlying distribution, e.g., whether one variable is a direct parent of the other. Bayesian model-selection attempts to find the MAP model and use its structure to answer these questions. However, when the amount of available data is modest, there might be many models that have non-negligible posterior. Thus, we want compute...

This paper describes a simple example of an institution that can maintain narrow bid ask spreads even in a market for a security where an uninformed specialist frequently trades with investors who have private information about the security’s value.

Given a graph G = (V,E) with strictly positive integer weights ωi on the vertices i ∈ V , a k-interval coloring of G is a function I that assigns an interval I(i) ⊆ {1, · · · , k} of ωi consecutive integers (called colors) to each vertex i ∈ V . If two adjacent vertices x and y have common colors, i.e. I(i)∩ I(j) 6= ∅ for an edge [i, j] in G, then the edge [i, j] is said conflicting. A k-interv...
