Three essays on corporate finance by Zou, Kunru

“…Taken together, our findings imply that debt covenants, which are designed to alleviate creditor-shareholder conflicts, may have unintended consequences of exacerbating the conflicts between creditors and other stakeholders. …”

Characterizing the Life Cycle of Online News StoriesUsing Social Media Reactions by Castillo, Carlos, El-Haddad, Mohammed, Pfeffer, Jürgen, Stempeck, Matt

“…We show that we can use this hybrid observation method to characterize distinct classes of articles. We also find that social media reactions can help predict future visitation patterns early and accurately.We validate our methods using qualitative analysis as well as quantitative analysis on data from a large inter-national news network, for a set of articles generating more than 3,000,000 visits and 200,000 social media re-actions. …”

The (lack of) distortionary effects of proxy-means tests: Results from a nationwide experiment in Indonesia by Banerjee, Abhijit, Hanna, Rema, Olken, Benjamin A., Sumarto, Sudarno

“…In a separate survey six months later, households in treated provinces report fewer televisions, though the effect dissipates thereafter. We find no change in actual television sales, or reported or actual SIM card ownership, suggesting that consumption distortions are likely small.…”

Representation theoretic interpretation and interpolation properties of inhomogeneous spin q-Whittaker polynomials by Korotkikh, Sergei

“…Moreover, we are able to characterize spin q-Whittaker polynomials in terms of vanishing at certain points, and we find interpolation analogues of q-Whittaker and elementary symmetric polynomials.…”

Landau-Zener transitions in a superconducting flux qubit by Johansson, J., Amin, M. H. S., Berkley, A. J., Bunyk, P., Choi, V., Harris, R., Johnson, M. W., Lanting, T. M., Lloyd, Seth, Rose, G.

“…The method used isolates a single qubit, tunes its tunneling amplitude Δ into the limit where Δ is much less than both the temperature T and the decoherence-induced energy level broadening, and forces it to undergo a Landau-Zener transition. We find that the behavior of the qubit agrees to a high degree of accuracy with theoretical predictions for Landau-Zener transition probabilities for a double-well quantum system coupled to a nonMarkovian 1 / f…”

Towards natural and realistic E7 GUTs in F-theory by Li, Shing Yan, Taylor, Washington

“…Three generations of Standard Model matter are realized in many of these vacua. We further find that many other Standard Model-like features are naturally compatible with these constructions. …”

Data artivism and feminicide by Suárez Val, Helena, D'Ignazio, Catherine, Acosta Romero, Jimena, Teng, Melissa Q, Fumega, Silvana

“…Our aim is to inspire the fields of critical data and data visualization studies to engage more deeply with art and find common language with artists, activists and advocacy groups (particularly those in Latin America), who are going beyond conventional visualization to reveal a range of alternative ways to mobilize data.…”

The impact of human capital and housing supply on urban growth by Büchler, Simon C, Niu, Dongxiao, Thompson, Anne K, Zheng, Siqi

“…To causally estimate this effect, we use a rich urban-level data set, choose our controls using the post-double-selection methodology, and instrument human capital with the per capita number of historical educational institutions. We find that human capital positively impacts urban population, house price and wage growth. …”

Contractor Learning and Home Energy Efficiency in Heat Pump Installations by Ontiveros, Johnattan H.

“…This work examines the role of learning on the cost and size of heat pump installations throughout the Massachusetts Clean Energy Center (MassCEC) rebate program. We find that as contractors gain experience, heating systems are downsized at the cost of less hours of displaced fossil-fuel based heating. …”

The Effect of Social Information on Reliance and Efficacy in AI-assisted Prediction by Alsobay, Mohammed

“…Through a pre-registered randomized human-subject experiment, I study the effect of two forms of social information-direct conversations and summarized peer decisions----on users' reliance and effectiveness in leveraging algorithmic advice across a series of decision-making tasks, and how t he availability of local model explanations and performance feedback moderates this effect. I find t hat, on average, neither form of social information affects t rust directly, yet they both moderate t he extent to which feedback and model explanations influence trust in the algorithm. …”

Explorations in two dimensional strongly correlated quantum matter: from exactly solvable models to conformal bootstrap by Jones, Robert A.

“…In the first project, we set out to answer: is it possible to find a lattice model in the Ising universality class that realizes the Kramers Wannier symmetry in such a way that it squares to 1, rather than a lattice translation as in the usual Ising model? …”

Natural Language Control for for Visually Interactive Decision Support Tools in Supply Chain Management by Guter, Willem J.

“…Various large language models are then evaluated for usability, functionality, and accuracy. We find that a state of the art commercial model is able to practically fulfill the role of a natural language interface, but that open-source large language models are not currently capable of functioning in this way.…”

Orthogonal vs. uncorrelated least squares discriminant analysis for feature extraction by Nie, Feiping, Xiang, Shiming, Liu, Yun, Hou, Chenping, Zhang, Changshui

“…To obtain great discriminative power between classes, all the data points in each class are expected to be regressed to a single vector, and the basic task is to find a transformation matrix such that the squared regression error is minimized. …”

Autonomous quality monitoring for complex manufacturing process by Lee, Wen Siong

“…This research investigates the possibilities of using different types of incremental learning algorithms and deep neural networks to monitor the quality of products produced from the complex manufacturing process through binary and multi-class classification to identify defects quickly. To find out which algorithm or neural network has the best result, I compared the performance of 4 different algorithms and 3 different neural networks using a set of time-series data collected as a result of the production of a transparent mold from the Molding machine. …”
