Does Nonbinding Commitment Promote Children’S Cooperation In A Social Dilemma?, Laurent Prétôt, Katherine Mcauliffe

Faculty Submissions

Communication is a powerful tool for promoting cooperation in adults and is considered one of the most important solutions to social dilemmas. One feature that makes communication particularly useful in cooperative contexts is that it allows people to advertise their intentions to partners. Some work suggests that adults cooperate more after making nonbinding commitments to cooperate (i.e., commitments they do not need to uphold) than when they are not allowed to communicate their intentions to their partners. However, we know little about whether nonbinding commitments play a similar role in children. We addressed this gap by testing 6- to 9-year-old …

An Exploratory Study Of Pulse Width And Delta Sigma Modulators, Logan B. Penrod

Master's Theses

This paper explores the noise shaping and noise producing qualities of Delta-Sigma Modulators (DSM) and Pulse-Width Modulators (PWM). DSM has long been dominant in the Delta Sigma Analog-to-Digital Converter (DSADC) as a noise-shaped quantizer and time discretizer, while PWM, with a similar self oscillating structure, has seen use in Class D Power Amplifiers, performing a similar function. It has been shown that the PWM in Class D Amplifiers outperforms the DSM [1], but could this advantage be used in DSADC use-cases? LTSpice simulation and printed circuit board implementation and test are used to present data on four variations of these …

Biological Siblings: Can You Trust Them With Your Mate?, Elisha Barron

Electronic Theses, Projects, and Dissertations

Recent studies suggest that genes may influence human mate preferences. What would this mean for same-sex siblings who share genes? Might they also share mate preferences and engage in mate poaching or would social norms and strong sibling bonds discourage such behaviors? We hypothesized that siblings would perceive their mate preferences to be more similar to their sibling’s than to an average person of their same gender. It was also hypothesized that the association between perceived sibling mate preferences and sibling mate poaching would be moderated by sibling closeness and sibling competition. Additionally, it was hypothesized that sibling mate competition …
