Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton

Theses - ALL

Accruing evidence suggests a significant relationship between sleep disturbances and disordered eating. Early adolescence is a period of heightened vulnerability for sleep disturbances and disordered eating. However, the longitudinal relationship between sleep disturbance and disordered eating remains unclear in early adolescent samples. The current study aims to examine if sleep disturbance longitudinally predicts disordered eating in early adolescents three years later, how the odds of having clinically significant disordered eating change per each unit increase in sleep disturbance, and if emotion dysregulation mediates these relationships. It is hypothesized that baseline sleep disturbance will predict greater disordered eating at follow-up, and …

Novel Origin Of Sperm Heteromorphism In The Drosophilidae, Karan Bhatt

Theses - ALL

Sperm heteromorphism, the production of two or more discrete sperm types or morphs within a single testis, occurs in diverse taxa. This phenomenon is believed to represent a division of labor by male gametes, with only one morph (the "eusperm") participating in fertilization and the other morph(s) specialized to perform some other (typically unknown) function within the female reproductive tract. One of the most intensively investigated systems is the Drosophila obscura species group, for which sperm heteromorphism evolved once in the common ancestor to the group, with all examined descendent species exhibiting sperm length heteromorphism. The absence of additional sperm …

Exploring The Role Of Astrocyte System Xc– In Excitatory/Inhibitory Balance, Samantha Olivia Sutton

Theses - ALL

Astrocytes play a central role in maintaining excitatory/inhibitory (E/I) balance in the central nervous system by supporting intracellular glutathione (GSH) synthesis and regulating extracellular glutamate. System xc– (Sxc–), an obligate cystine/glutamate antiporter encoded by SLC7a11, couples the import of L-cystine with the export of L-glutamate. It is highly expressed throughout the cortex, hippocampus, striatum, and cerebellum, where its activity provides cystine—the rate-limiting substrate for cysteine-dependent GSH production—and contributes to ambient glutamatergic tone. Although global loss of Sxc– alters seizure threshold and redox homeostasis, whether these effects arise specifically from the loss of astrocytic Sxc– has remained unresolved. This thesis examined …

Virtually Present In The Vastness: Vr’S Pathway To Awe And Appreciation, David Paul Peters

Dissertations - ALL

This dissertation explores how spatial presence in Virtual Reality (VR) creates awe and appreciation through the role of perceived vastness. 92 participants played a custom-built VR game (VR Nature Photographer) in three environments designed to be low, medium, and high in vastness. A repeated-measures design measured spatial presence, vastness, awe, and appreciation across conditions. Results showed higher vastness increased all four outcomes, with awe and vastness having the largest effect sizes and presence and appreciation medium sized. Mediation analyses showed perceived vastness fully mediated the effect of spatial presence on awe in all vastness conditions and partially mediated its effect …

Extensive Superficial Dermatomycosis Caused By Cladophialophora Sp., A Deep Mycosis Pathogen: A Case Report, Nikko Vanda Limantara, Agnes Sri Siswati, Flandiana Yogianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Background: Superficial dermatomycosis, predominantly caused by dermatophytes, affects approximately 20–25% of the global population. However, non-dermatophytic fungi, such as Cladophialophora species (sp.), can also cause similar cutaneous infections. Although less common, these organisms are particularly concerning in immunocompromised individuals.

Case Illustration: A 66-year-old immunocompromised male presented with widespread pruritic and erythematous patches, initially misdiagnosed as tinea corporis. Despite receiving standard antifungal therapy, his condition persisted. Further investigation through fungal culture identified Cladophialophora sp., which was resistant to common antifungal agents such as fluconazole, itraconazole, and ketoconazole. However, the fungus was sensitive to terbinafine, which has …

How Narrative Storytelling On Social Media Develops Relationships Between Authors And Readers, Madelyn Woodson

Theses - ALL

With the rise of social media being used to sell products and connect communities, it is important to understand how creators are developing relationships with viewers. A specific community where this is evident is BookTok, where readers and authors can connect over shared interests. Understanding how, in this case, relationships are built between readers and authors can be broken down by looking at elements of trust, satisfaction, and commitment which stem from the Organization Public Relationship (OPR) theory developed by Hon and Grunig (1999). Research has shown that personalization and storytelling when creating content and communicating with publics develops a …

Immigration And Public Support For Social Policy: Accounting For The Gender Composition Of Immigrant Populations, Achim Edelmann, Friedolin Merhout, Amie Bostic

Sociology Faculty Publications

With increasing global mobility, scholars have debated whether immigration undermines welfare states. So far, no conclusive evidence of a consistent association between immigration and social policy support has emerged. This might be due to treating immigrants as a monolithic mass. To begin addressing this, the authors account for the gender composition of immigrant populations. Drawing on research on attitudes toward immigration, immigration policy, and gendered tropes of immigrants, the authors develop two hypotheses detailing how the share of women among immigrants moderates that population’s impact on individuals’ social policy support. Testing these hypotheses on International Social Survey Programme and United …

Impact Of Dividend Policy On Share Price Volatility: Evidence From Sri Lanka, Maleesha Piumini Panangala, Neluka Devpura, Ravindra Lokupitiya

Bulletin of Monetary Economics and Banking

This paper investigates how dividend policy affects share price volatility among companies on the Colombo Stock Exchange from 2012 to 2020, including the COVID-19 period. Using a fixed effects model that explains 70% variability, we find both dividend per share and payout ratio significantly reduce share price volatility. Results remain robust even after excluding 2020 data. We identify several policy implications including how our results are useful for policy makers in understanding financial market instability and how investors can factor information in forecasting market prices.

The Impact Of Increasing News Intensity And Number Of Investors On The Relationship Between News Sentiment And Price Movement In The Developing Country: Indonesian Evidence, Zaäfri Ananto Husodo, Muhamad Nagib Alatas

Bulletin of Monetary Economics and Banking

This study examines how news intensity and investor numbers affect the link between news sentiment and equity price movements in Indonesia, using the LQ45 Index. Applying methods such as correlation analysis, CAPM, VAR, Granger causality tests, and rolling correlations, we find that higher news intensity and investor participation strengthen the connection between news sentiment and stock returns while also increasing volatility. The findings suggest that incorporating news sentiment analysis can improve market stability and investment decisions in developing economies.
