Recommender systems (RSs) have become essential tools that provide personalized recommendations to their users. These systems may consider user, item provider, and system requirements simultaneously. With the inclusion of possibly clashing considerations, there is a growing focus on solving multiple-objective recommender system (MORS) problems as efficiently as possible. The constrained...
We establish the criterion for chaos in three-planet systems, for systems similar to those discovered by the Kepler spacecraft. Our main results are as follows: (i) The simplest criterion, which is based on overlapping mean motion resonances (MMRs), only agrees with numerical simulations at a very crude level. (ii) Much...
A great deal of work has been done in recent years to construct algebraic invariants ofLegendrian knots, and their higher-dimensional analogues. Here we employ the diagram-
matic calculus developed in [3], in order to develop an iterative method for computing the
so-called vexillary functions of a class of Legendrian surfaces....
Autism spectrum disorder (ASD) and intellectual disability (ID) are two of the most highly prevalent neurodevelopmental disorders (NDDs), each affecting roughly 2% of the population. Despite the need for therapies, few exist due to a myriad of challenges, such as the complex underlying genetic etiology and historic inaccessibility of neural...
The production and spread of digital news involves a wide range of actors: journalists and the organizations that employ them, social media platforms, audiences, and myriad commentators, citizen journalists, bloggers, and other actors who contribute to the news ecosystem without inhabiting an official role. These actors interact in flexible, often...
This dissertation presents an affect-centered approach to the analysis and interpretation of the experience of music and its attendant meaning in selected works of literature and cinema. Music’s interpretative mutability often charges it with meaning, though in infinite gradations of singularity rather than any universal sense. Rather than undertake a...
Vertebrate brains evolved to facilitate a diverse array of behaviors and internal cognitive processes. Theories of neural function have proposed that neural computation is organized within populations or ensembles of neurons. Here, we identify ensembles of neurons in the striatum, the main input nucleus of the basal ganglia, in which...
This dissertation studies three markets with regulated prices. I focus on how these regulations shape the behavior of firms along non-price dimensions. Chapter 1 studies the effects of community rating regulations in the US individual health insurance exchange market. In this market, the Affordable Care Act established community rating areas...
The dissertation project considers the generative possibilities to envision Black subjectivity that emerges from a sustained consideration of different forms of difficult racial and sexual intimacies. The artists whose work is engaged throughout the project, Leasho Johnson, Ajamu X, and NIC Kay recognize that to be Black is to always...
Chapter 1. Caste, Bureaucracy, and the Limits to Political Affirmative Action. The aim of political affirmative action policies is to ensure that disadvantaged groups are represented in their governments and, in turn, that laws preferred by this group are more likely to be instituted. Often, however, they have not been...
