Codable robots, small electronic devices programmed with software or apps, have become popular toys for children to play with at home. During play, children learn about coding by programming their robot to move and behave however they choose. But given the novelty of coding, children may face impasses when coding...
By assessing infants’ movements, our research goal was to determine if particular movement characteristics are indicators for cerebral palsy (CP), a disorder caused by a brain injury to the fetus/infant that leads to impaired development of movement. Our research may contribute to developing an earlier diagnosis for CP, and therefore...
Examining fertility knowledge and identifying knowledge gaps in those who may need to delay childbearing is essential, especially for individuals who may be pursuing higher education. Educating these individuals is also critical as prior research has confirmed that fertility awareness may modify future reproductive choices and outcomes. The primary goals...
The revitalization of endangered languages is both deeply personal and political, as language subjugation is directly linked to intentional efforts by colonizing powers to suppress and eradicate indigenous culture and dismantle local collective identity. Many studies have been conducted on how to promote endangered languages, but few evaluate the effectiveness...
Stories and fantasy represent an important aspect of consumer life and comprise a huge marketing enterprise within consumer entertainment. Each year, upwards of $82 billion is spent on books, games, and other fantasy industries in the United States alone. Likewise, fantasy has important implications for consumers’ sense of identity. In...
In my dissertation I explore several applications of collective household models with limited commitment to study the behavior of singles and couples in the modern US marriage markets in presence of endogenous risk of divorce. In the first chapter, I show that the model is capable of rationalizing the patterns...
We prove the Rigidity Conjecture of Goette and Igusa, which states that, after rationalizing, there are no stable exotic smoothings of manifold bundles with closed even dimensional fibers. The key ingredients of the proof are fiberwise Poincaré–Hopf theorems generalizing earlier such results about the Becker–Gottlieb transfer. These theorems show how...
This dissertation is divided into three chapters. Chapter one studies changes in market concentration and productivity growth in the United States from the 1990s to the 2010s. Chapter two measures the impact of a banking crisis, the British Panic of 1825, on non-financial firms. Chapter three examines how women's employment...
Earth’s mantle has a two-layer structure comprising an upper and a lower mantle, separated by a global seismic discontinuity at 660 km depth. The mantle transition zone (MTZ), which extends from the seismic discontinuity at 410 km depth to the base of the upper mantle plays a crucial role in...
Miniaturized lasers are important for fundamental studies of light-matter interactions and applications in on-chip photonic integration. Plasmonic nanoparticle lattices supporting surface lattice resonances can provide optical feedback for directional lasing emission at room temperature. This thesis focuses on how the design of plasmon cavities can enable engineering of laser emission...
