Every day, we communicate through computers on projects ranging from a group lunch order to booking a flight to learning critical medical information. And every day, we also miscommunicate through computers: We don’t pick up on an intentionally humorous response, or we miss the criticality of a request. This is...
The speed of the storage device has long lagged behind the computation speed of processors.As a result, the I/O performance of storage systems in a supercomputer fails to keep up with its computational power.
This gap continues to widen in modern supercomputers.
On future exascale supercomputers, this issue can worsen...
As machines take over the work of producing, organizing, and curating culture, it becomes increasingly important to examine the influence of algorithms in public memory work, through which the past is selectively and subjectively reconstructed to make meaning in the present. Accordingly, this dissertation intervenes at the intersection of public...
Many computing technologies are primarily useful because of the existence of some set of data created by people, intentionally in some cases and unintentionally in others. For instance, technologies like search engines, recommender systems, classifiers, and language models are all dependent on digital records of things people have said, done,...
Since the mid-20th century, urbanization has altered the physical landscape and brought social, economic and lifestyle changes to populations worldwide. In the Global South, this has dramatically affected environmental conditions of settlements, communities, and households, with both positive and negative consequences for population health. The objective of this dissertation is...
Tumor-initiating cells with reprogramming plasticity are thought to be essential for cancer development and metastatic regeneration in many cancers; however, the molecular mechanisms are not fully understood. We have previously identified that CD44, a breast tumor-initiating cell marker, drives mammosphere self-renewal and multicellular aggregation of circulating tumor cell (CTC) clusters,...
Given the enormous diversity that exists in our society today, the need intensifies for educators to create a transformative environment that fosters productive encounters with the differences that emerge in a diverse society. Nonetheless, limited attention has been devoted to generating a systematic understanding of how students engage with and...
Phonotactic patterns are generalizations that govern the order of consonants and vowels, within words and syllables. Certain second-order phonotactic patterns—those that relate multiple sounds within a syllable, such as “if the vowel is [ɪ], then [s] can only appear at the end of the syllable”—require a period of sleep-based consolidation...
Making the Coast Pacific is an environmental history of violence against places, plants, and people. Mexico's Pacific Coast region was a key site for oilseed agriculture and industrialization, which resulted in environmental violence and injustice. Since the region with Mexico's largest population of afro-descendants, Costa Chica, was also Mexico's leading...
In this dissertation, I conducted 2 studies that resulted in 3 manuscripts. This dissertation consists of 6 chapters that include the 3 manuscripts. The overarching research question is How does context affect the work of quality improvement (QI) practitioners? To answer this larger research question, which is central to the...
