Exploring The Synthesis, Characterization, And Aggregation Properties Of Perylene Diimide Derivatives, Erica Salinas

Honors Theses

Once widely used for its vivid presence in an array of industrial dyes, perylene-3, 4, 9, 10-tetracarboxylic dianhydride (PTCDA) is a known precursor for perylene diimides (PDIs). These compounds are an alternative for sustainable energy within organic solar cells (OSCs) and for improving organic light emitting diodes (OLEDs). PDIs are a great candidate for organic semiconductor applications because of their overall flexibility and low manufacturing cost as an organic photovoltaic. Its extended π-conjugation results in a planar structure promoting strong π- π intermolecular stacking, giving aggregated PDIs high electron mobility, allowing a flow of electrons to move through these stacked …

Nutritional Knowledge Of Collegiate Track Athletes, Haleigh Risner

Honors Theses

There are rising concerns on whether collegiate athletes are being diligent with their nutritional practices. With an increase in RED-S (Relative Energy Deficiency in sports) cases in athletes, their knowledge about their nutritional needs comes into question. Nutrition has a significant impact on athletic performance and the development in an athlete’s specialty. To assess the current knowledge of athletes, the track athletes of East Texas A&M University were asked to participate in a nutritional assessment to determine their knowledge of nutrition in regard to their sport. It was hypothesized that the majority of athletes surveyed would not possess adequate knowledge …

Enhancing E-Learning Recommendation Systems Using Latent Dirichlet Allocation (Lda), Zanbaq Hikmet Thanon, Javad Salimi Sartakhti

Mesopotamian Journal of Big Data

Although the wide range of instructional materials, might overcome students and limit their capability to learn effectively, platform of education become important for providing personalized learning. Traditional recommendation systems (RS) try to resolve this issue; yet, they fail in understanding learning content semantically. This restriction makes it more difficult for them to deliver accurate, useful, and clear recommendations. The aim of this study is to enhance E-learning RS using topic modeling, specially the Latent Dirichlet Allocation (LDA) method, to discover latent structures within educational content. The ``20 Newsgroups'' dataset that containing over 20,000 items across 20 categories used to evaluate …

When Flood Warnings Fail: Psychological Predictors Of Information Clarity And Evacuation Intention, Katsuya Tanaka, Tadashi Kito, Kohji Tanaka

Center for Public Service Publications and Reports

Flood warnings are often assumed—particularly within traditional average-effect models—to prompt uniform behavioral responses, yet real-world evidence suggests that message effectiveness varies widely across the population. This study empirically identifies and explains such heterogeneity using a factorial survey experiment (n = 1671) conducted among residents in flood-prone regions of Japan. We estimate finite mixture beta regression models to disentangle the distinct behavioral patterns underlying information clarity and evacuation intention. Results reveal two psychological segments: a Responsive majority, whose decisions are shaped by concrete and credible warning attributes (e.g., specific breach point, forecast basis, large-font display), and a Non-Responsive minority, who remain …

Angkringan Names In Semarang: A Linguistic Landscape Study, Nurul Maghfiroh, Suhandano Suhandano, Aprillia Firmonasari

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

The article reveals the linguistic landscape study of angkringan names in Semarang City. It covers language preference, language inference, and language preservation on signages. Researchers collected 140 pictures of angkringan signages from 10 sub-districts of Semarang. Observation and interviews are also conducted to obtain comprehensive linguistic landscape data. Qualitative analysis indicates that there are two naming patterns: monolingual and bilingual. The monolingual analysis identifies that the most preferred language code is Javanese, followed by Indonesian, English, and Sanskrit. Meanwhile, in the bilingual pattern, the dominant language combination used is Indonesian-Javanese, followed by Javanese-English, Javanese-Indonesian, Javanese-Dutch, Sanskrit-English, and Sundanese-English. Meanwhile, angkringan …

Single-cell analysis of human triple-negative breast cancer revealed heterogeneous macrophage populations with opposing phenotypes - proinflammatory and proresolution of inflammation. Paradoxically, both subsets accumulated in therapy-refractory residual tumors but showed inverse correlations across patients, suggesting mutually exclusive resistance mechanisms. Inflammatory macrophages localized preferentially to epithelial-like tumors, whereas proresolution macrophages were enriched in mesenchymal-like tumors. Mouse models faithfully recapitulated these patterns. After chemoimmunotherapy, mesenchymal-like tumors expanded proresolution macrophages through phagocytosis/efferocytosis, ω-3 fatty acid uptake, and resolvin production. Macrophage-secreted C1q emerged as a principal antagonist of T cell function by targeting mitochondria and inducing metabolic dysfunction. By contrast, epithelial-like tumors accumulated inflammatory …

The Road To Senior Leadership: Senior-Level Administrative Women Leaders In Division I Intercollegiate Athletic Departments, Susan E. Richard

Electronic Theses and Dissertations 2020 - Present

This qualitative narrative study examined the career pathways and lived leadership experiences of women serving in senior-level administrative roles within Division I intercollegiate athletics, a traditionally male-dominated industry. Guided by a crucible leadership framework, the study explored how formative experiences shaped participants’ leadership development, professional advancement, and persistence. Nine women who currently or previously served as senior-level administrative leaders participated in the study. Data were collected using an adapted version of Seidman’s three-interview series, supplemented by document analysis and a demographic survey to support triangulation. Interviews were organized into three phases to chronologically capture participants’ career trajectories.

The findings are …

High Germinability Can Facilitate Recovery Of Adelia Vaseyi (Euphorbiaceae), An Imperiled Tamaulipan Thornscrub Shrub, Saroj Dhakal, Bashira Chowdhury, Alejandro Fierro-Cabo

School of Earth, Environmental, & Marine Sciences Faculty Publications

While critical to maintaining dryland biodiversity and drought resilience, reforestation has been limited in subtropical dry forests because of knowledge gaps in seed biology that must be filled to upscale seedling production and ensure recovery of imperiled endemic plants. We characterized seed germination, dormancy, and storage needs for Adelia vaseyi, a threatened endemic shrub commonly included in planting mixes to restore Tamaulipan thornscrub, an imperiled subtropical forest spanning South Texas and Northeastern Mexico. We found A. vaseyi seeds have high germinability (82.0%) and a short mean germination time (3.04 ± 0.08 days). A delia vaseyi seed does not appear …

Synthesis Of Cu2znsns4 (Czts) Semiconductor Thin Film With Variation Of Sulfur Solution Concentration, Sri Sugiarti, Farhan Dandi Nugraga, Ahmad Sjahriza

Chimica et Natura Acta

The Cu2ZnSnS4 (CZTS) thin film is an alternative semiconductor material as a light absorbing layer in solar cells. The advantages of CZTS as a light absorbing layer are the availability of abundant materials in nature and high absorption coefficient values. The absorbent layer was prepared using the sol-gel and spin coating method on an indium tin oxide (ITO) glass substrate. Films were made with a sol-gel solution with varying concentrations of sulfur solution, namely with a concentration of 3M and 6M using a simple spin coating tool which was rotated for 30 seconds. The film formed was hardened at 550°C …

Brown Pelican (Pelecanus Occidentalis) Groundings On A Four-Lane Divided Highway In South Texas: A Comparative Study Using Citizen Science, Bradley Evan Beer, Kevin W. Ryer, Md. Saydur Rahman, John H. Young Jr., Richard J. Kline

School of Integrative Biological & Chemical Sciences Faculty Publications

The population of the once-endangered brown pelican (Pelecanus occidentalis) has increased over the past several decades and is now considered fully recovered. However, in south Texas, the combined effects of weather patterns, transportation infrastructure, and brown pelican biology have led to road mortalities on State Highway 48 (SH 48) at the Carl “Joe” Gayman Bridge. To mitigate these mortalities, the Texas Department of Transportation modified traffic barriers on SH 48. We aimed to examine the effect of the barrier change and determine which weather variables influence brown pelican groundings on SH 48. Citizen scientists monitored sections of SH …
