Spatial Structure Formation By The Post-Transcriptional Gene Regulator Rsme In Pseudomonas Fluorescens Pf0-1, Anton Evans

Electronic Theses and Dissertations

Microorganisms are often found in microbial communities we call biofilms. Organisms living in these crowded environments have significant evolutionary pressure to retain access to the resources necessary to sustain life. My research uses the bacterium Pseudomonas fluorescens Pf0-1 to study how organisms evolve strategies to solve this crowding problem as aging colonies repeatedly generate mutant patches. These mutants expand the reach of the colony resulting in decreased local density as they push themselves up to the resource rich surface. These spatial structures result from social interactions between the mutant and the parental cells mediated through extracellular secretions, resulting in the …

Maladjustment Among Victims Of Bullying, Jack Bryant

Electronic Theses and Dissertations

Bullying has garnered attention from educators, social scientists, and the public at large for nearly 50 years, but the dilemma persists. We have seen that bullying is a high-risk factor for psychological adjustment across the lifespan. The current study has surveyed college students to ascertain their perceptions of adjustment in adult life. The study has added to the existing literature in addressing the role of reduced perceived control in the maladjustment of bully victims. A novel contribution was made by comparing the strength of this potential mediator to another documented correlate of poor adjustment among bullying victims, thwarted belonging.

Choosing Sides: Military Behavior In Severely Polarized Democracies, Timothy W. Ford

Electronic Theses and Dissertations

Why does severe polarization result in military intervention in some cases but not others? I argue that the organizational culture unique to a particular military plays a critical role in influencing behavioral outcomes in severely polarized democracies. When faced with sovereign power disputes that arise as a result of severe polarization, military organizations are most likely to develop new strategies of action from the dominant practices, norms, and ideas of military leaders. Severe polarization presents a unique threat to civil-military relations and provides the type of unsettled social periods in which cultural ideologies express an observable influence on military behavior. …
