My Whine, Your Wine

Description: Grapes hold the flavors of the lands where they grow, and when you make wine from them, those flavors of the land come through. Tasting wine from a place you've been can bring you back to that place with aromas and notes indicative of that place. A bottle of wine changes every day, and how it will taste depends on the moment you choose to release it from the glass walls. I have a vested interest in wine, because it is a living thing. I am compelled to make wine because its characteristics are l… more

Boosting for Learning From Imbalanced, Multiclass Data Sets

Description: In many real-world applications, it is common to have uneven number of examples among multiple classes. The data imbalance, however, usually complicates the learning process, especially for the minority classes, and results in deteriorated performance. Boosting methods were proposed to handle the imbalance problem. These methods need elongated training time and require diversity among the classifiers of the ensemble to achieve improved performance. Additionally, extending the boosting method to… more

“No Paper Cowboys”: Stories

Description: Equilibrium is paramount in the crafting of a story, and for every writer this sense of balance is different. The writer must manage a balance of showing and telling, of denotation and connotation, and forever strive to find the perfect word in both the denotative and connotative sense, so that the reader and writer can meeting in a living story—both in the ink on the page and the remaining white space.

Expertise Revisited: Reflecting on the Intersection of Science and Democracy in the Case of Fracking

Description: This dissertation aims to explain the conditions under which expertise can undermine democratic decision making. I argue that the root of the conflict between expertise and democracy lies in what I call insufficiently “representative” expertise – that is forms of scientific research that are not relevant to the policy questions at hand and that fail to make visible their hidden values dimensions. I claim that the scholarly literature on the problem of expertise fails to recognize and address th… more

Relationships Among Self-esteem, Psychological and Cognitive Flexibility, and Psychological Symptomatology

Description: Previous findings on the relationship between self-esteem and psychological outcomes are inconsistent. Therefore it appears that self-esteem, while related to crucial variables, does not provide a clear, direct, and comprehensive prediction of psychological symptoms. Thus, it was hypothesized that the relationship between self-esteem and symptomatology would be moderated by broader measures of how one interacts with emotional and cognitive stimuli.The purpose of this study was to examine the in… more

The Limits of Arbitrage and Stock Mispricing: Evidence from Decomposing the Market to Book Ratio

Description: The purpose of this paper is to investigate the effect of the "limits of arbitrage" on securities mispricing. Specifically, I investigate the effect of the availability of substitutes and financial constraints on stock mispricing. In addition, this study investigates the difference in the limits of arbitrage, in the sense that it will lead to lower mispricing for these stocks, relative to non-S&P 500 stocks. I also examine if the lower mispricing can be attributed to their lower limits of arbit… more
