An Investigation Of Bidder Behaviour In Wic Infant Formula Rebate Auctions, Ashma Pandey

Electronic Theses and Dissertations

This research investigated the competitive bidding dynamics for infant formula rebate contracts within the Special Supplemental Nutrition Assistance Program for Women, Infants, and Children (WIC). I begin by focusing on the differences between winning and losing bids. The study employs multiple regression to predict rebate bids submitted by major manufacturers when they win a contract. I next conduct a paired t-test for each manufacturer – revealing statistically significant differences between predicted bids (based on the parameters from the winning model) and actual bids when a manufacturer did not win. This suggests that each manufacturer bids significantly lower rebates (higher net …

Refining The Inverse Lipschitz Constant For Injective Relu Networks, Cole Rausch

Electronic Theses and Dissertations

In this thesis, we study the Inverse Lipschitz Constant (ILC) of injective ReLU layers. We study the tightness of the ILC lower bound established in Puthawala et al. Our approach has three components. First, we find that the conditions for injectivity on lines yield a weaker condition than the general condition given in Puthawala et al. Second, we perform numerical experiments to judge the tightness of the existing ILC lower bound and find that bound is overly conservative. Third, we identify the source of the potential slack in the proof of the existing ILC bound, and perform further numerical experiments …

Reimagining Hunting Through Women's Decision Space, H. Nash Jackson

Electronic Theses and Dissertations

Approximately 14.4 million people hunt in the United States, yet only 3.1 million (22%) of these hunters are women. To enhance women’s participation, many state natural resource agencies aim to reduce barriers and create pathways for women to hunt. Previously, researchers surveyed women to understand and describe barriers to their full participation in hunting. However, this methodology often just quantifies the different barriers without describing the interconnectedness and how the complexity of barriers can impact women’s participation in hunting. This thesis instead took an inductive research approach with the goal of better understanding women’s perspectives when faced with complex barriers. …

Organizational Culture's Impact On Job Satisfaction: A Reconceptualization Of The Competing Values Framework, Isaac Thor Erickson

Electronic Theses and Dissertations

Academic job satisfaction has been decreasing in the U.S. which has profound negative impacts such as burnout and decreased well-being of employees. One way that job satisfaction can be increased is through understanding and changing organizational cultures through better communication. The Competing Values Framework (CVF; Quinn & Rohrbaugh, 1983; Belasen & Frank, 2010; Lund, 2003) has been used to understand how organizational cultures and their communicative norms relate to job satisfaction. However, the CVF relies on categorical measures sitting on two axes that are not orthogonal. As such, the study posits breaking these two axes into four dimensions of organizational …
