ENVIRONMENTAL FEATURES INFLUENCE COMPLEX BEHAVIOR IN SMALL GROUPS OF ANIMALS
Simple environmental features can shape complex behavior. Identifying key aspects of the environment (e.g., temperature, structure, toxins) that lead to widespread consequences is of central importance in a changing world. The primary objective of my dissertation is to investigate how relatively …

The complex behavior of poly(dte) carbonate and its blend properties
… material identified temperature regions where complex thermal events were occurring. From the experiments it was determined that at certain temperatures poly(DTE) carbonate dipoles spontaneously rearranges while an electric field is across the polymer. Multiple thermal regions were identified …

Cloning and Characterization of the Vasopressin-Oxytocin Neuropeptide Signaling System in the Vocal Control System of the Zebra Finch (Taeniopygia guttata)
… have long demonstrated their influence on social behaviors in mammals. Comparative analyses of these neuropeptides and in-depth analyses in non-mammalian species may reveal the specific mechanistic roles these hormones play in social behavioral functioning. The acquisition of complex behavioral …

Modeling collective dynamics of social systems: Incorporating various social mechanisms into agent-based models
<p>I present three original papers demonstrating complex behavior arising from collective dynamics in agent-based models (ABM) focusing on evolutionary and cognitive mechanisms. The first report demonstrates the coupled emergence of cooperation and selfish punishment behavior in groups of …

Time-Setting Generalization Assessment of Mentally Retarded Adults' Acquired Self-Control in the Preparation of Complex Meals After Withdrawal of Training Components and Trainers
… of mentally retarded individuals' acquired complex behavior. Specifically, the ability of three moderately mentally retarded adults to prepare complex meals in their own apartments, during and after a partial-sequential withdrawal of training components and trainers, was examined. First, …

Evaluation of uncertainty in dynamic, reduced-order power system models
… and the desire to analyze increasingly complex behavior in power systems, simulation techniques are gaining importance and prevalence. However, while simulations of large, interconnected power systems are feasible, they remain time-consuming. Additionally, the models and parameters used …

Effects of Concurrent Fixed Interval-fixed Ratio Schedules of Reinforcement on Human Responding.
… changes in the value of one schedule affected behavior reinforced on another schedule. Second, switching from one pattern to the other functioned as an operant unit, showing stability during schedule maintenance conditions and sensitivity to extinction. These effects are discussed in the …

Odorant Responses and Courtship Behaviors Influenced by at4 Neurons in Drosophila
… pheromones function as triggers to elicit complex behavior programs, such as courtship and mating. In most species, the neurons tuned to pheromones are localized in a specific subset of olfactory sensilla located on the antenna called trichoid sensilla. In Drosophila there are two classes …

Convex modeling with priors
As the study of complex interconnected networks becomes widespread across disciplines, modeling the large-scale behavior of these systems becomes both increasingly important and increasingly difficult. In particular, it is of tantamount importance to utilize available prior information about the …

Foraging in a Complex World: From Individual Flight Performance to Collective Behavior in Bumblebees (Bombus Impatiens)
Foraging is a crucial and remarkably complex behavior that is key to survival. For social insects such as bumblebees, successful foraging depends on a combination of individual traits (e.g. physiological and biomechanical performance of individual workers) and collective behavioral strategies for …
