Louder and Stronger? The Role of Signaling and Receptivity in Democratic Breakdowns and Their Impact Upon Neighboring Regimes

Description: The purpose of this thesis is to establish what specific forces influence whether or not a democratic setback within one nation will diffuse to peripheral states. Past studies devoted to this topic have largely suggested that diffusion essentially functions like a contagious disease, where the likelihood of "infection" is primarily based upon the level of interaction between states. This thesis however proposes that the interaction of the signal generated from a democratic state's collapse an… more

Observing and Attending in a Delayed Matching-to-Sample Preparation in Pigeons

Description: Pigeons worked in a titrating delay match-to-sample (TDMTS) procedure in which selecting the correct comparison stimulus increased the delay between sample offset and comparison-array onset and incorrect comparison selections decreased that delay. Prior research in our lab has shown that the stable adjusted value of the retention interval is a curvilinear function of the observing response requirement. The current study examined the effect of the distribution and predictability of observing re… more

Effects of Fixed- and Variable-Ratio Token Exchange Schedules on Performance with Children with Autism

Description: The research literature with nonhumans supports findings that token economies are a common component of training programs. The literature suggests that the schedule by which exchange opportunities become available determines the organization of behavioral performances in token economies to a great extent. This study sought to systematically document whether the dynamics observed in basic laboratory procedures will also be observed in a child diagnosed with autism spectrum disorders and wheth… more

Errors in skin temperature measurements.

Description: Numerical simulation is used to investigate the accuracy of a direct-contact device for measuring skin-surface temperature. A variation of thermal conductivity of the foam has greater effect on the error rather than a variation of the blood perfusion rate. For a thermal conductivity of zero, an error of 1.5 oC in temperature was identified. For foam pad conductivities of 0.03 and 0.06 W/m-oC, the errors are 0.5 and 0.15 oC. For the transient study, with k=0 W/m-oC, it takes 4,900 seconds fo… more

Extermination Warfare? The Conduct of the Second Marine Division at Saipan

Description: Historians John W. Dower, Craig Cameron, and Ronald Takaki argue that the Pacific War was a war of extermination fueled by race hate. Therefore, the clash between the military forces of the Japanese Empire and United States of America yielded a "kill or be killed" environment across the battlefields of the Pacific. This work examines the conduct of the Second Marine Division during its campaign of conquest against the Japanese held island of Saipan from June 15, 1944-July 9, 1944. It is base… more
