Exploring The Stem Career Identity Development Of Black Women Across Their Lifespan, Veronica Hurd Jan 2025

Exploring The Stem Career Identity Development Of Black Women Across Their Lifespan, Veronica Hurd

Theses and Dissertations

Although STEM is the fastest-growing career sector, Black women are grossly underrepresented as they account for 2.5% of the workforce. Research highlights that this underrepresentation is due to racialized structures in K-12, postsecondary, and career settings that restrict Black girls’ and women’s STEM opportunities. While macrosystems such as hegemonic ideologies, attitudes, and social conditions shape Black girls’ and women’s opportunities in STEM, they continue to persist and achieve their career goals. To explore these barriers and Black women’s persistence in this industry, this study draws from the autobiographical memories of 10 Black women in the field or formerly in the …


Multitask Learning For Named Entity Recognition And Relationship Extraction, Adrienne D. Hembrick Jan 2025

Multitask Learning For Named Entity Recognition And Relationship Extraction, Adrienne D. Hembrick

Theses and Dissertations

Information Extraction (IE) is a fundamental task in Natural Language Processing (NLP), involving the identification of structured information from unstructured text. Two core components of IE—Named Entity Recognition (NER) and Relation Extraction (RE)—are widely used to extract key concepts and the relationships between them across various domains. However, the sequential dependency of RE on the output of NER makes it vulnerable to error propagation: inaccuracies in entity recognition can negatively affect downstream relation extraction.

To mitigate this issue, Multitask Learning (MTL) has been proposed as an approach that jointly models NER and RE, aiming to improve overall performance and reduce …

No significant year effects emerged for the other themes. Two-way MANOVAs indicated that gender, first-generation status, and major did not significantly predict engagement, nor did they interact with year. In contrast, classification emerged as the most consistent predictor, with upper-division …


Using A Dimension Reduction Approach To Parse Heterogeneity In Dietary Restriction, Amanda Makara Jan 2025

Using A Dimension Reduction Approach To Parse Heterogeneity In Dietary Restriction, Amanda Makara

Theses and Dissertations

Dietary restriction, the problematic reduction of caloric or macronutrient intake, is a critical eating behavior occurring transdiagnostically across eating disorders and subclinical disordered eating. The definition of dietary restriction is highly heterogeneous, and restriction is often conflated with other distinct constructs, such as dietary restraint. The current practices related to the definition and measurement of dietary restriction have notable flaws, negatively impacting the ability to identify and establish risk, diagnosis, and treatment of eating disorders. There is also limited evidence that commonly-used dietary restriction measures can validly predict food choice and objective intake. These issues raise questions about whether dietary …
