Normal gastroesophageal motilty is important to live a comfortable and healthy life. Motility disorders result in impaired transport of ingested food which can lead to extreme discomfort and severe damage to the walls of the esophagus. Significant work has been done to study gastroesophageal motility using advanced diagnostic tools such...
The shoulder is the most mobile joint in the human body, allowing for the execution of complex and athletic tasks. Unfortunately, such expansive mobility comes at a cost. The shoulder is prone to instability, or painful symptoms associated with increased humeral head translation, and dislocation. To prevent dislocations and maintain...
This thesis considers identification, estimation, and inference in nonparametric settings. Special attention is given to identification with instrumental variables of small support, and in time series via the ergodic assumption. Chapter 1 considers a nonparametric instrumental regression model in which the regressor and instrument are discretely distributed. Here, we strengthen...
In this dissertation, we study and prove formulas of Hodge ideals for three types of isolated hypersurface singularities, including quasihomogeneous singularities, Newton non-degenerate singularities and analytically irreducible plane curve singularities.
For quasihomogeneous singularities, we provide
a formula of Hodge ideals of $D=\alpha Z$ which is a Q-divisor.
A direct consequence...
The electric grid is changing rapidly with a proliferation of new technologies being integrated. There is a need to analyze the growth in technologies to help move towards a carbon-free electricity sector such as renewable generation and large scale battery installations. This is occurring at the same time as the...
This dissertation is a cultural history of state-sponsored film in India and Iran. I focus on the 1960s-1980s, a period during which both countries enacted sweeping development agendas, which included industrialization, the expansion of higher education, and social reforms. I engage in a comparative analysis of each state’s pedagogies of...
Motivated by real-world problems in various fields, mechanism design governs the design of protocols for strategic agents and has applications both in computer science and economics. Due to the revelation principle – a seminal observation in mechanism design, a vast number of studies in mechanism design focus on revelation mechanisms...
Depression is a challenging mental illness that requires individuals to manage their moods and emotions over time. While past mental health literature describes how individuals seek and share support on social media and within online communities, the ways that offline and one-on-one supportive interactions unfold is less clear. To address...
This dissertation consists of three essays that deal with problems of information acquisition and aggregation and the incentives to acquire such information. The first of the essays is titled The Timing of Complementary Innovations and studies the problem of an agent that acquires information about the viability of a project...
This dissertation comprises three essays in distinct areas of economic theory. The first chapter is co-authored with Gregorio Curello. We identify a new and pervasive dynamic agency problem: that of incentivising the prompt disclosure of productive information. To study it, we introduce a model in which a technological breakthrough occurs...
