The damaging effects of toxic stress can disrupt the normal course of brain, immune, and metabolic development, placing children at increased risk for mental and physical health problems that can last into adulthood. Counselors are uniquely qualified to help prevent and treat early childhood toxic stress. Yet, gaps between counseling theory, research, and …

“The War Will Be Over Sometime”: Female Authorship, Time, Trauma, And Healing In H.D.’S Wartime Works, Loren Samons

Electronic Theses and Dissertations

As a tripartite collection of poems, at first glance H.D.'s Trilogy appears vastly different from her semi-autobiographical novel, Bid Me to Live, but the two are not as removed from each other as their formats and publication timelines might indicate. In fact, their connectedness is much less discreet than many scholars have suggested. In addition to being thematically similar in terms of their considerations of time and gender, Bid Me to Live and Trilogy could be viewed as works in conversation with each other, reflecting the development of the female authorial voice along a timeline of war-related trauma progression and …

Novel Formulation Strategies For Oral And Ocular Drug Delivery, Samir Senapati

Electronic Theses and Dissertations

Nanoformulations such as nanoemulsions (NE), solid lipid nanoparticles (SLN), and nanostructured lipid carriers (NLCs) are colloidal particulate systems in the submicron size range and act as carriers of drug molecules. Their size varies from 10 to 1,000 nm (1). The capacity of these nanoparticles to permeate through many anatomical barriers, the prolonged release of their contents, and their stability on the nanometer scale have widely contributed to their efficacy in drug delivery. Owing to the advantages of nanoformulations, they were further explored in our studies to target different diseases like Dry eye disease (DED), glaucoma, and malaria.

The Effect Of Mandated Disclosure On Liquidity Among Not-For-Profit Organizations, Erin Johnson

Electronic Theses and Dissertations

This study examines whether mandated disclosure under Accounting Standards Update (ASU) 2016-14 affects not-for-profit (NFP) liquidity. ASU 2016-14 requires NFPs to disclose information that enhances financial statement users’ ability to assess an organization’s liquidity. Using panel data from fiscal years 2014 through 2019, I compare liquidity before and after the mandated disclosure for the top 100 revenue generating NFPs in 2019. I find that NFPs manage operating reserves, i.e., unrestricted liquid net assets, more closely to NFP sector guidelines after the disclosure mandate. Specifically, I find that NFPs with operating reserves above the recommended range prior to the disclosure mandate …
