Machine Learning For Asphaltene Polarizability: Evaluating Molecular Descriptors, Arun K. Sharma, Owen Mcmillan, Selsela Arsala, Supreet Gandhok, Rylend Young

Biology, Agriculture and Chemistry Faculty Publications and Presentations

Asphaltenes are complex polycyclic organic molecules in crude oil that readily aggregate and precipitate under varying thermodynamic conditions. Their structural heterogeneity influences key physicochemical properties, including solubility, stability, and reactivity. Molecular polarizability, a crucial property governing intermolecular interactions and electronic behavior, remains challenging to predict due to this structural diversity. This study employs machine learning models to predict isotropic polarizability using two sets of molecular descriptors: WHIM and GETAWAY. A dataset of 255 asphaltene structures was analyzed using stratified sampling, generating 10 independent training (80 %) and testing (20 %) splits.

A Design Based, Mixed Method Study On Evaluating Traditional Grading Practices And The Implications For Mastery Learning And Educational Equity In A Midwestern School District, Christina Kirchner

Dissertations

“Grades are an essential currency of our schools. Schools, colleges and employers use grades to determine many important, and in some cases, life-altering decisions-college admission, financial aid and scholarships, athletic eligibility, promotion, retention, awards, and supports” (Feldman, 2018, p. 3). Grading is not addressed in teacher preparation programs, or within professional development during teachers’ careers; teachers have chosen their own way to grade guided by their own personal experiences, uninformed of research or best practice. Using a human centric, design-based approach, the researcher identified multiple discrepancies with grading practices among the K-12 school organization. Within the discrepancies, other issues were …

Reimagining School Leadership: Latinx Administrators Leveraging Community Cultural Wealth To Support Latinx Student Success: A Qualitative Study In East San Jose Grounded In Counter-Storytelling, Critical Race Theory, And Latino Critical Theory, Alexis Corona Pimentel

Social Justice in Educational Leadership EdD Dissertations

This qualitative study examines how Latina administrators in East San Jose leverage their Community Cultural Wealth (Yosso, 2005) to support Latinx student success in K-12 education. Although Latinx students comprise the largest racial/ethnic group in California public schools (California Department of Education, 2021), Latinx leaders remain significantly underrepresented in educational leadership. Guided by Critical Race Theory (Delgado & Stefancic, 2017), Latino Critical Race Theory (LatCrit) (Solórzano & Bernal, 2001), and Yosso’s (2005) framework of Community Cultural Wealth, this study centers the counter-stories of three Latina administrators to explore how their cultural identities, lived experiences, and relational practices inform leadership.
