Anthropology Faculty Publications and Presentations

Dental microwear texture analysis (DMTA) has proven to be a valuable tool for separating bioarchaeological samples by subsistence practice, preferred diet, food-processing technology, and cooking method. In this study, we compared samples of individuals from two South Indian sites-an Iron Age site (Adichchanallur, similar to 4010 BP, n = 27) and an Early Historical site (Keeladi, similar to 2600 BP, n = 31). Both samples represent farming communities that likely had broadly similar diets dominated by cultivated rice and mung beans, wild nuts and pulses, and both domesticated cattle and wild game. Moreover, the archaeological evidence indicates that both communities …

Khaled Hosseini’S Judgment In The Kite Runner Towards Pashtun And Hazara Identities, Bilal Waziri, Dawod Mangal, Kamaldeen Kamal

Journal of Research Initiatives

This book review offers a compelling examination of Khaled Hosseini's portrayal of Pashtun and Hazara identities in his acclaimed novel, *The Kite Runner*. Through a literary-ethnographic lens, the research delves into how narrative techniques can construct, amplify, or distort ethnic representations, particularly within the tumultuous backdrop of Afghanistan. The novel is scrutinized for its stark depiction of Pashtuns as oppressors and Hazaras as perennial victims, which risks perpetuating a simplistic and problematic singular narrative. Employing a library-based qualitative approach, this paper thoughtfully interprets textual evidence within the rich sociocultural and historical landscape of Afghanistan. The findings reveal that while the …

Appearance Over Function - The Impact Of Long-Term Oral Contraceptive Use On Brain Development, Breast Tissue Composition, And Future Lactation Outcomes, Fiona M. Wang

Dissertations

This integrative review examines the long-term effects of combined oral contraceptive (COC) use beginning in puberty on brain development, breast tissue composition, and future breastfeeding outcomes. Puberty is a critical developmental stage during which hormonal changes significantly impact the neurological and reproductive systems. The introduction of synthetic estrogen and progestin through COC use during this time may disrupt natural hormonal pathways, potentially altering neuroendocrine signaling and breast tissue maturation. Such changes may have lasting consequences, including impaired milk production, a weakened milk ejection reflex, disrupted maternal-infant bonding, and reduced overall breastfeeding success. The review synthesizes findings from endocrinology, neuroscience, and …

Effect Of Short-Chain Polymer Binders On The Mechanical And Electrochemical Performance Of Silicon Anodes, Fei Sun, L. Zurita-Garcia, Dean R. Wheeler

Faculty Publications

Polymer binders are crucial components in providing both mechanical support and chemical stability to the structure of porous Li-ion electrodes. Particularly in silicon anodes, the active material undergoes substantial volume expansion of up to 275%. Due to the mechanical constraint of the current collector, these silicon materials tend to expand in the normal direction while exhibiting substantial particle rearrangement and plastic deformation. Conventional rigid binders such as polyacrylic acid (PAA) and polyimide (PI), while providing satisfactory initial capacity, do not eliminate diminished long-term performance. Our research attempts to develop binder formulations that can accommodate sufficient flexibility for the substantial volume …

Feed Prices, Substitution Patterns, And Technical Efficiency In Feedlot Cattle, Andrew E. Anderson, James L. Mitchell, Jamie R. Luke

Agricultural Economics and Agribusiness Faculty Publications and Presentations

The cattle feeding industry is sandwiched between relatively volatile commodity markets, and efficiency is critical. Changing prices for feedstuffs may cause substitution and output effects, in turn impacting technical efficiency. Using Kansas feedlot data, we estimate the effects of feed prices on cattle performance, focusing on the feed conversion ratio, average daily gain, and days on feed. Results show that several feed prices do indeed impact technical efficiency. These results have implications for management adapting to changing feed prices. Further, there are policy implications for programs that may impact commodity prices.

Investigating The Offsets Between The Clumped Isotope Signatures Of Various Species Of Benthic Foraminifera, Ceara Hogan Yourell

Master's Theses and Capstones

For much of the last half century, the primary tool for reconstructing ancient ocean temperatures was the oxygen isotope paleothermometer. However, this method is fundamentally limited by its reliance on assumptions about the δ¹⁸O value of seawater, which introduces uncertainty into paleotemperature estimates. The clumped isotope paleothermometer (Δ47) offers a promising alternative by directly measuring the stochastic "clumping" of heavy isotopes (¹³C and ¹⁸O) within the carbonate lattice—a process governed solely by temperature and independent of seawater isotopic composition (Ghosh et al., 2006; Eiler, 2007). While Δ47 paleothermometry has been applied successfully in diverse contexts, including reconstructing extinct animal body …

Consumption Of Negative Media Content Mediates The Association Between Levels Of Trauma Exposure And Insomnia Severity In Hispanic Young Adults, Michiyo Hirai, Laura L. Vernon

Psychological Science Faculty Publications

Research has shown that individuals who have experienced traumatic events are at greater risk of developing severe insomnia than those without trauma. Further, according to the stress sensitization hypothesis, victims of multiple traumas, compared to those who have experienced a single trauma, are particularly vulnerable to severe insomnia. One potential mechanism underlying the association between trauma experiences and insomnia is media exposure. Although avoidance behaviors are symptoms of posttraumatic stress, victims of traumas also demonstrate attentional bias toward threats and difficulty disengaging attention from threats. These cognitive tendencies may result in heightened vigilance to negative media content, particularly trauma-related content, …

Faculty, Staff and Students Publications

Chagas disease, caused by the protozoan Trypanosoma cruzi, is a significant challenge for canine health, with limited diagnostic tools. This study assessed the performance of a novel Tc-24 recombinant antigen ELISA compared to three commercial diagnostic tests on 70 serum samples from kennel dogs in Texas. The Tc-24 ELISA demonstrated high sensitivity (87.5%) and specificity (91.2%) compared to Indirect Fluorescent Antibody (IFA) testing, with significant differences in Tc-24 optical density (OD) between positives and negatives (0.607 vs. 0.089, p < 0.001). When compared to Chagas Stat-Pak (SP), Tc-24 ELISA showed sensitivity and specificity values of 82.1% and 86.7%, respectively (p < 0.001). For Chagas Detect Plus (IB), the assay achieved a sensitivity of 80.0% and specificity of 93.1% (p < 0.001). Spearman correlation analysis revealed significant associations between Tc-24 OD and SP (r = 1.0, p = 0.0167), IB (r = 0.9, p = 0.0833) and IFA (r = 0.6273, p = 0.044). Elevated immunochromatographic values in commercial kits (SP or IB) correlated with Tc-24 OD (1.17 vs. 0.039, p < 0.001), achieving 100% sensitivity and 95.8% specificity based on positive results from commercial kits. These findings suggest that Tc-24 ELISA is a reliable and accurate serological tool for diagnosing T. cruzi infection in dogs, with the potential to enhance diagnostic capabilities in veterinary medicine.

Acute Loss Of Tactile Input Leads To General Compensatory Changes In Eye-Hand Coordination During Object Manipulation, Kevin Ung, John F Magnotti, Brandon Kim, Jeffrey M Yau, Per F Nordmark

Faculty, Staff and Students Publications

Current models of motor control emphasize the critical role of sensory feedback, as demonstrated by movement coordination deficits following sensory impairment. When both vision and touch are available for object-oriented manual behaviors, they serve distinct roles; vision guides the execution of planned movements, while touch provides more direct feedback on hand-object interactions. The impact of losing somatosensory feedback on eye-hand coordination during dexterous object manipulation tasks has not been thoroughly studied. Conceivably, vision is recruited to compensate for the feedback lost when touch is abolished based on the dexterity demands of the behavior. To investigate this, we tested healthy participants …
