High Fidelity – No Evidence for Extra-Pair Paternity in Siberian Jays (Perisoreus infaustus)

Extra-pair paternity (EPP) in birds is related to a number of ecological and social factors. For example, it has been found to be positively related with breeding density, negatively with the amount of paternal care and especially high rates have been observed in group-living species. Siberian jays (Perisoreous infaustus) breed at low densities and have extended parental care, which leads to th...

It is seldom possible to plausibly define and observe a pool of potential entrants to a market. This study overcomes that limitation by taking advantage of an opportunity to reasonably define the potential entrants into MTBE production, a rapidly growing environmental product from the mid-1980’s to mid-1990’s. Potential entrants are identified as those firms having access to specific assets tha...

Jay Cummings: Research Statement

My research has touched many areas of combinatorics, including enumerative, algebraic, spectral, extremal and probabilistic. The projects below include finding the stationary distribution of a random coloring procedure, pursuing new directions in the math of juggling, working with undergraduates on Ramsey theory, and studying a pair of topics from spectral graph theory. I have mentored undergra...
