Structural colors originate from the interaction between the incident light and a surface with periodic submicron structures. They enable the creation of a spectrum of nonfading colors, potentially replacing toxic metal oxides and conjugated organic pigments. However, significant challenges remain, including lack of contrast needed for the complete gamut of...
Algorithmically-driven social platforms present a challenge for self-presentation and identity management by obscuring audiences behind algorithmic mechanisms. Users are increasingly aware of this and actively adapting through folk theorization, but we do not know how users are coping with the constant change endemic to these platforms. We also do not...
In this thesis we study two problems, one in unsupervised learning - k-means clustering and the other in a supervised learning setting with the presence of adversarial perturbations. We do a beyond-worst case style analysis and show that in either case instances that are resilient to adversarial perturbations are also...
Hypnaesthesis argues for understanding somnambulism, nightmare, and insomnia as aesthetic categories in the gothic and dark romantic traditions of antebellum American literature that provide critical insights into the experiential costs of the exhortations to normative vigilance prevalent in the American Enlightenment. During this period unceasing vigilance became the watchword for...
“Open Tables: Restaurants and Reform in Progressive Chicago” considers restaurants as contentious spaces where larger debates about gender, class, race and ethnicity, public health, and the role of the state were carried out between the end of the Civil War and the ratification of the 18th Amendment. Using Chicago as...
Conceptually, we can divide this dissertation into Chapter 1 which is in the tradition of information economics and comparative statics, and Chapters 2 to 4 which had all its genesis in the same project concerning identifying the value of product differentiation to consumers with minimal assumptions, and is therefore related...
There is strong evidence for the benefits of teaching parents of toddlers with autism spectrum disorder (ASD) intervention strategies for facilitating language development. A strategy at the core of early parent-mediated interventions for ASD is responsiveness, defined as providing a child with a verbal response each time she communicates. Responsiveness...
This dissertation addresses three distinct topics in development economics. The first chapter assesses the role of entry and exit in the measurement of misallocation in India. In the last decade, misallocation of productive inputs across firms has been proposed as a primary driver of differences in aggregate productivity over time...
Western scientific norms (e.g., Bacon, 1623/2005) dictate that mechanistic explanations like “rain falls because clouds form water vapor” are preferable to teleological ones like “rain falls so that plants should grow. Do people have preferences that naturally align with this? The predominant interpretation of past research is that they do...
Commonsense inference is a critical capability of modern artificial intelligence (AI) systems. The machines need commonsense knowledge to perform tasks exactly like human being does. Learning commonsense inference from text has been a long standing challenge in the field of natural language processing due to reporting bias -- people do...
