The paper and poster competitions provide valuable experience to graduate students in presenting research results. The contests are part of every North Central Meeting. The presentations consistently set high standards for presentations that we use to communicate the results of our research efforts. We acknowledge all the participants of the student contest. We also thank more than 40 contest judges for their time, effort and insight in ranking the presentations.
There were 53 papers and 29 posters in this year's NCWSS Graduate Contest. The awards consisted of a certificate and a check, $50 for second place and $100 for first place.
