A Polyphasic Investigation Of Terrestrial Green Algal Diversity Of Biological Soil Crusts From The California Channel Islands, Emily Masluk

Masters Theses

Biological soil crusts (BSCs) in arid and semiarid environments support diverse microbial communities that contribute to soil stabilization, nutrient cycling, and ecosystem resilience. Among these organisms, terrestrial green algae are taxonomically challenging due to their simple morphology, phenotypic plasticity, and lack of diagnostic life history traits. This study investigated the diversity and taxonomy of green algae from BSCs collected on San Nicolas Island, San Clemente Island, and Santa Barbara Island using the polyphasic approach integrating morphology, phylogenetic analyses, molecular analyses, and ecological data. A total of 198 strains were isolated, of which 79 green algal strains underwent molecular analysis using …

An Ecology Of The Monstrous: How Readers Shape And Are Shaped By Monster Romance, Allison D. Rayburn

Master's Projects

This thesis is a Composition and Rhetoric study of the monster romance genre, a growing yet often misunderstood site of rhetorical activity.

Sketching Ot Theory: The Meaning Of Visual Notetaking To Learning Occupational Therapy Theory For Ot Students, Julia Henderson, Delainey Ebel, Ilona Jones, Katie Lee Bunting

Journal of Occupational Therapy Education

Visual notetaking is a creative learning strategy used in health professions education. This study defines it as any form of notes, recorded using physical or electronic means, that are not solely text-based, but incorporate some degree of color, symbolism, shapes, diagrams, and/or other visual imagery to represent concepts. While no previous studies have investigated visual notetaking in the context of occupational therapy education, occupational therapy’s prevalent use of visual representations to convey complex, relational, and holistic theoretical concepts suggests that visual notetaking may have potential as an inherently aligned and effective pedagogical approach for teaching occupational therapy theory. Our study …

(Wp 2026-01) Du Bois And Veblen's Concepts Of Relative Position: Common Ground Or Stratification Economics And Institutionalist Economics, John B. Davis

Economics Working Papers

W. E. B. Du Bois and Thorstein Veblen employed the concept of relative position. Du Bois' thinking reflects how for Stratification economics people's relative positions explain racial discrimination and segregation. Veblen reflects how for Institutionalist economics people's relative positions explain the role institutions have in the evolution of the economy. Racism in the US marginalized Du Bois' contributions, leaving a divide between his and Veblen's thinking and also between Stratification economics and Institutionalist economics. This has limited the perceived importance of the concept of relative position in economics, leaving it with the 'position-less' asocial individualism of Neoclassical-mainstream economics. This paper …

Machine Learning: Thematic Feature Grouping, And The Magnificent Seven: A Forecasting Analysis, Mirarmia Jalali, Mohammad Najand, Andrew Cohen

Finance Faculty Publications

This study examines the predictability of monthly excess returns for the “Magnificent Seven” U.S. technology firms using machine learning and economically motivated thematic feature grouping. Framed as a focused study of the most systemically consequential equity panel in modern markets—seven firms representing over 30% of the S&P 500—the analysis confronts a small-N, large-P environment where economically structured dimensionality reduction is essential. Using 154 firm-level characteristics categorized into 13 economic themes, we evaluate linear, penalized, tree-based, and neural network models in a small-N, large-P setting. Unrestricted models suffer substantial overfitting and fail to outperform the historical average benchmark out-of-sample. In contrast, …

International Evidence On The Relationship Between Financial Literacy And Corporate Cash Holdings, Kenneth Yung, Reza Kahibavil, Su Li, Arian Amidi

Finance Faculty Publications

This study is the first investigation of the relationship between corporate cash holdings and financial literacy (FL). We find that a one‐standard‐deviation increase in FL is associated with an 8%–27% reduction in corporate cash holdings, depending on the measure of FL used. Moreover, higher FL reduces the market value of excess cash, indicating that financially literate environments discourage value‐destroying cash accumulation. The results remain robust across alternative definitions of FL and cash holdings, estimation methods, and country subsamples. We further rule out the influence of endogeneity, refinancing risk, and variation in cash needs. Additional analyses identify agency costs as the …

How Operational And Disclosure Complexity Shapes The Conglomerate Discount, Feng Dong, John A. Doukas, Son Wilson, Rongyao Zhang

Finance Faculty Publications

This study examines how firm operational diversification and disclosure complexity jointly drive the conglomerate discount. We disentangle disclosure complexity, which is determined by managerially influenced financial transparency, from accounting complexity, which is a direct informational consequence of operational complexity. We find that operational diversification is consistently associated with significant conglomerate discounts, while disclosure complexity independently reduces firm value and amplifies the magnitude of the discount when diversification is high. These findings suggest that transparent disclosures can mitigate valuation costs, offering important implications for managers seeking effective communication, investors assessing complex firms, and policymakers aiming to enhance disclosure quality and market …

Ceo-Employee Pay Ratio Disclosure And Dividend Policy, Rajib Chowdhury, John A. Doukas

Finance Faculty Publications

We examine whether and how the magnitude of the CEO pay ratio affects dividend policy in the context of inequality-averse investors. Our results demonstrate a positive association between the two and remain robust to endogeneity concerns. We find that the CEO pay ratios positively affect dividends irrespective of whether CEO compensation contracts motivate risk-averse or risk-taking policy choices. This non-diverse effect on dividend policy across CEOs with different pay structures contradicts previous studies and highlights the wealth effect resulting from the SEC mandate. Further analyses reveal a negative effect of the pay ratio on cash holdings and investment inefficiency.

Efficacy Of Endophytic Fungi In The Management Of Spoladea Recurvalis (Lepidoptera: Crambidae) On Amaranth (Amaranthus Dubius), Druscilla Obonyo Nyamamba

All Master’s Theses

Amaranth is a Traditional African Vegetable (TAV) that in recent years has gained global popularity due to its exceptional nutritional, medicinal and economic attributes. However, its production is significantly limited by insect pest infestations, mainly lepidopteran defoliators. Spoladea recurvalis, commonly known as Hawaiian beet webworm has been reported as the major pest that feeds voraciously on the leaves leading to substantial yield losses of up to 100% under severe pest infestation. Chemical control remains a widely used method for the management of S. recurvalis. The use of fungal endophytes has emerged as a promising, sustainable and eco-friendly alternative to …
