Online Multiobjective Optimization, Kristen Joyce

All Dissertations

Online optimization (OO) is an iterative process of decision making under uncertainty. At every step, a decision is made before the outcome of this decision is known. For the online optimization model, the objective function is unknown at the time the decision is being made. It is very likely that the taken decision is not optimal, so the decision maker incurs a loss, called regret, in every iteration. The goal of the online optimization algorithm is to compute a decision at every step so that the overall regret cost is minimized. In particular, the average regret produced by an ideal …

While contemporary playground design often struggles to balance structure with creativity, …

Flipping The Script?: The Development And Validation Of A Qualitative Framework For Identifying Key Cognitive And Attitudinal Components Of Conflict-Based Problem Representations, Kyle Christenson

All Dissertations

When people work together, disagreements are inevitable. How someone understands a given conflict, specifically whether they see it as a shared problem or not, can shape how they respond and whether they look to resolve it collaboratively. Researchers have studied many aspects of conflict, like what causes it and the strategies people use to manage it. But we know much less about how people think about conflict in the first place and how those thoughts affect efforts to manage conflict. This research developed a tool to study how people describe conflicts in writing. It identifies key ideas and attitudes that …

Ecomorphological Diversification Of Tooth Complexity In The Oral Jaws Of Marine Teleostean Fishes, Keiffer L. Williams

All Dissertations

Teeth are essential biological tools that function as a direct interface between predator and prey, thus providing essential insights into the evolutionary history and ecological diversity of vertebrates. Historically, studies on vertebrate dentitions have been qualitative and focused on mammals. More recently, quantitative methods have been developed that can reliably measure tooth surface complexity. These methods have been applied across both mammals and saurian reptiles to test for correlations with diet, leading to the conclusion that herbivorous species generally possess higher overall tooth complexity than any other dietary group. Surprisingly, the relationship between tooth complexity and diet in the most …

From Cities To Ranches: Assessing Public Support For Jaguar (Panthera Onca) Conservation And Livestock Predation In Colombia, Luz Angelica Solano

All Dissertations

Jaguars are among the most emblematic large carnivores worldwide. Nonetheless, the species has declined by 25% in less than 25 years and their range has been reduced by 55%, approximately, primarily due to habitat loss from increasing agricultural development, retaliatory killings from human-jaguar conflict, and overhunting of their natural prey. Given the anthropogenic nature of these threats, developing effective coexistence strategies and public support for jaguar conservation are increasingly urgent for the continued persistence of this species. I conducted a scoping review to assess trends and gaps in the existing peer-reviewed literature, grey literature, and news articles related to human-jaguar …

Interactions Of Biorational And Synthetic Dmi Fungicides For Control Of Fruit Diseases, Johanna Wesche
