Concurrent Algorithms in Transactional Data Structures
(2017-07-14)Software transactional memory (STM) simplifies the challenging, yet increasingly critical task of parallel programming. Using STM allows programmers to reason about concurrent operations in terms of transactions—groups of ... -
Conducting Social Network and Social Norm Research in Low-Resource Settings: Food Insecurity, Depression, and HIV Testing in Rural Uganda
(2015-05-18)This dissertation examines the role of social networks and social norms in health outcomes and behaviors among low-and middle-income countries (LMICs), with a particular focus on Uganda. Paper 1 presents a systematic review ... -
Confessional Fictions: Penance in Medieval Romance c.1150-1450
(2020-09-11)This study explores medieval romance in relation to religious changes from the twelfth to fifteenth centuries. While the genre has been viewed as secular literature in tension with spiritual instruction, authors such as ... -
A Configurable Terasample-per-second Imaging System for Optical SETI
(2013-10-08)A new instrument for conducting astronomical searches for nanosecond-scale optical pulses has been designed, built, and is now operating at Oak Ridge Observatory in Harvard, MA. The Advanced All-sky Camera, based on the ... -
Confirmed Tranquility: The Stoic Impulse in Transatlantic Romanticism
(2014-06-06)Spontaneous feeling has been a cornerstone of Romantic aesthetics since Wordsworth wrote his Preface to Lyrical Ballads. This dissertation unsettles the link between Romantic poetry and the overflow of emotion by arguing ... -
Conformal Bootstrap in Two Dimensions
(2016-05-18)In this dissertation, we study bootstrap constraints on conformal field theories in two dimensions. The first half concerns two-dimensional (4,4) superconformal field theories of central charge c=6, corresponding to ... -
Conjuring the Masses: The Figure of the Crowd in Modern Chinese Literature and Visual Culture
(2012-10-22)This dissertation argues that the figure of the crowd in literature and visual culture constitutes a crucial component in the emergence and construction of the cultural, political, and historical values of modern China. ... -
Connecting Both Sides of the “Admission Desk”: Contextual Data from High School Counselors and Factors Influencing Its Quality
(2023-05-08)In recent years, selective colleges have embraced the use of contextual data in their holistic assessments of undergraduate applicants. Background data about students’ school and home environments can enable admission ... -
The Connection between Microphysical Morphology and Atmospheric Particle Phase Transitions
(2013-02-11)The phase of atmospheric particles can influence heterogeneous chemistry, cloud formation, and radiative forcing. Sulfate particles ranging from sulfuric acid to ammonium sulfate are the largest contributor arising from ... -
Connectivity and computations in higher-order olfactory neurons in Drosophila
(2014-06-06)Understanding how odors are encoded in the brain is of fundamental importance to neurobiology. The first two stages of olfactory information processing have been relatively well studied in both vertebrates and invertebrates. ... -
Consequences of Caspase Inhibition in Differentiating Myoblasts
(2017-09-07)The apoptotic caspases are proteases that mediate the process of programmed cell death. Canonically, their activation is a point of no return; however, the disruption of myoblast differentiation resulting from caspase ... -
Consequences of Government Provision and Regulation of Health Insurance
(2012-11-07)The first two chapters of this dissertation concern the effect of public catastrophic insurance programs. In the first chapter, I show how these programs, which only protect against large health shocks, induce advantageous ... -
Conserved Genetic Modules Controlling Lateral Organ Development: Polycomb Repressive Complex 2 and ASYMMETRIC LEAVES1 Homologs in the Lower Eudicot Aquilegia (Columbine).
(2013-09-18)Development in multicellular organisms relies on establishing and maintaining gene expression profiles that give cells identity. Transcription factors establish gene expression profiles by integrating positional, temporal, ... -
Constituents at the Gate: European Political Parties and the Representation of Migration-Background Communities
(2015-01-15)This dissertation looks at migrant-background voters in Germany and the Netherlands to explain variations in descriptive representation in these two countries, and to find mechanisms which may explain the broad variations ... -
Constrained Bayesian Optimization and Applications
(2015-05-17)Bayesian optimization is an approach for globally optimizing black-box functions that are expensive to evaluate, non-convex, and possibly noisy. Recently, Bayesian optimization has been used with great effectiveness for ... -
Constrained Portfolios and Asset Prices
(2022-05-11)In this Thesis, I focus on analyzing constrained investors' trading behavior and its asset pricing implications. In the first Chapter, we focus on analyzing the effect of investors' expectations on market dynamics. ... -
Constraining Subduction Zone Processes Through Local, Regional, and Global Chemical Systematics
(2015-04-08)Subduction zones recycle material from Earth’s surface into the mantle, and are an important means of continent building. The subduction system serves as a stamp, imprinting the distinct chemical characteristics of our ... -
Constraining the Evolution of Galaxies over the Interaction Sequence with Multiwavelength Observations and Simulations
(2013-10-18)Interactions are crucial for galaxy formation and profoundly affect their evolution. However, our understanding of the impact of interactions on star formation and activity of the central supermassive black hole remains ... -
Constraints on Electromagnetic Parity Violation in the Cosmic Microwave Background using BICEP3
(2023-12-11)Conservation of parity in the electromagnetic (EM) force is a generally accepted assumption for the Standard Model of physics. This need not be true, however, and a number of frameworks have been invented which predict ... -
Constraints on Global Carbon Cycling, Basin Formation, and Early Animal Evolution During the Neoproterozoic and Early Cambrian
(2015-09-25)Within this dissertation, I document different time intervals during the Neoproterozoic through the early Cambrian (1000 – 525 Ma), one of the most dynamic and non-uniformitarian intervals in the history of the Earth. This ...
