Unusual High-Frequency Mechanical Properties Of Polymer-Grafted Nanoparticle Melts, Mayank Jhalaria, Yu Chang, Yucheng Huang, Brian C. Benicewicz, Sanat K. Kumar, George Fytas

Faculty Publications

Brillouin light spectroscopy is used to measure the elastic moduli of spherical polymer-grafted nanoparticle (GNP) melts as a function of chain length at fixed grafting density (0.47  chains/nm²) and nanoparticle radius (8 nm). While the moduli follow a rule of mixtures (Wood’s law) for long chains, they display enhanced elasticity and anomalous dissipation for graft chains <1⁢0⁢0  kDa. GNP melts with long polymers at high 𝜎 have a dry zone near the GNP core, surrounded by a region where the grafts can interpenetrate with chain fragments from adjacent GNPs. We propose that the departures from Wood’s law for short chains are due to the effectively larger silica volume fraction in the region where sound propagates—this is caused by the short, interpenetrated chain fragments being pushed out of the way. We thus conclude that transport mechanisms (of gas, ions, sound, thermal phonons) in GNP melts are radically different if interpenetrated chain segments can be “pushed out of the way” or not. This provides a facile new means for manipulating the properties of these materials.

Sexual Relationships During Covid-19, Katherine Hahn-Boisvert

Honors Capstones

During the early parts of COVID-19, no one knew what to expect. In a world where it was suddenly unacceptable to shake hands or give a hug, how did sexually intimate couples navigate being sexually intimate? In this study, sexual self-disclosures, relationship satisfaction, and sexual communication satisfaction were measured during the COVID-19 pandemic. The costs and rewards of COVID-19 related self-disclosures was also measured to see what people thought was the costliest and how it would impact a sexually intimate relationship. Data was collected using an online survey which had 15 participants. The results indicated that COVID-19 had a negative …

Defund The Police: Snappy Slogan Or A Viable Solution? A Case Study Of Savannah, Georgia, Michayla F. Knox

Honors College Theses

The notion of defunding the police remains a hot-button political topic since the protests of Summer 2020. The forefront of the debate concerns how defunding the police will impact crime rates. Still, the topic has scarcely been investigated empirically. This thesis provides an early examination into the relationship between "defunding the police", reallocating funding, and crime rates in Savannah, Ga. Several experiments are performed to answer three research questions that involve comparing and manipulating the budget provided for policing and the budgets for neighborhood vitality and poverty reduction. The findings show that Savannah allocates significantly more money to the policing …

Student Perceptions Of Gendered Racial Microagressions, Ayanna Brewton

Honors College Theses

The impact of stereotypes, prejudice, and discrimination is a widespread issue in society that has become more visible to people with privilege and has been more widely studied by social scientists and mental health professionals. More recently, the impact of gendered racial microaggressions has been investigated. Gendered racial microaggressions are defined as indirect and everyday slights and insults based on the intersection of racism and sexism (Gadson & Lewis, 2021). Research shows that gendered racial microaggressions toward multiple minority status individuals has a negative impact on their mental wellbeing (Mekawi & Todd, 2018). However, there is a gap in the …

Effects Of Water Quality On Oyster Health On Georgia Coast, Laurel Henderson

Honors College Theses

ABSTRACT

Oysters are an economically and ecologically important shellfish species found along most coastlines. Along the Georgia coastline, oysters form extensive reefs, and are economically important as a food source. In addition, oysters perform a vital role in maintaining water quality due to their high filtration capacity in coastal waters. Oyster reefs form solid, 3-D substrate that prevent coastline erosion and provide structure for numerous other coastal species to grow, including many commercially and recreationally important species. Water quality factors, such as temperature and salinity, can influence oyster density, condition, and growth, and ultimately affect the services the reefs provide …

Humanising Health And Social Care Support For People With Intellectual And Developmental Disabilities: Protocol For A Scoping Review, Madison Milne-Ives, Rohit Shankar, Dan Goodley, Kirsten Lamb, Richard Laugharne, Tracey Harding, Edward Meinert

Peninsula Medical School

Background Health care is shifting toward a more person-centered model; however, people with intellectual and developmental disabilities can still experience difficulties in accessing equitable health care. Given these difficulties, it is important to consider how humanizing principles, such as empathy and respect, can be best incorporated into health and social care practices for people with intellectual and developmental disabilities to ensure that they are receiving equitable treatment and support. Objective The purpose of our scoping review is to provide an overview of the current research landscape and knowledge gaps regarding the development and implementation of interventions based on humanizing principles …

Are You Paid For Your Hard Red Winter Wheat Quality? Yes, But Indirectly, Shane Roberts, Kathleen Brooks, Lia Nogueira, Cory Walters

Cornhusker Economics

Hard red winter wheat (HRWW) is the largest wheat class grown in the United States, with approximately 660 million bushels produced in 2020, representing about 36% of total U.S. wheat production (USDA ERS 2021). The world market is an important destination for U.S. HRWW. In 2020, exports of U.S. HRWW represented 52% of U.S. production and total U.S. wheat exports represented 13% of total world exports (USDA ERS 2021). U.S. HRWW differs from other wheat classes based on physical characteristics such as color, kernel hardness and planting season as well as consistency in producing end uses such as pan and …

Public Health Impacts Of The Clothing Industry, Schafer Flowerday

Department of Environmental Studies: Undergraduate Student Theses

The clothing industry is worth $1.5 trillion dollars and rapidly expanding (Statista, 2021). The industry is dominated by fast fashion, which accounts for clothing that is quickly and cheaply produced, based on ever-changing trends. 90% of textiles produced are made in low-income countries, predominantly in South Asia (Seigel, 2011). This systematic literature review looks into the impact this industry has on these vulnerable populations which are working and living in areas where clothing is produced. Environmental and Occupational health hazards and impacts were researched. Environmental impacts occur at each step of the process. Polyester is the most common textile, and …

Emergency Medicine Articles

Early in the coronavirus disease 2019 (COVID-19) pandemic, global governing bodies prioritized transmissibility-based precautions and hospital capacity as the foundation for delay of elective procedures. As elective surgical volumes increased, convalescent COVID-19 patients faced increased postoperative morbidity and mortality and clinicians had limited evidence for stratifying individual risk in this population. Clear evidence now demonstrates that those recovering from COVID-19 have increased postoperative morbidity and mortality. These data-in conjunction with the recent American Society of Anesthesiologists guidelines-offer the evidence necessary to expand the early pandemic guidelines and guide the surgeon's preoperative risk assessment. Here, we argue elective surgeries should still …

Factored Beliefs For Machine Agents In Decentralized Partially Observable Markov Decision Processes, Joshua A. Lapso, Gilbert L. Peterson

Faculty Publications

A shared mental model (SMM) is a foundational structure in high performing, task-oriented teams and aid humans in determining their teammate's goals and intentions. Higher levels of mental alignment between teammates can reduce the direct dialogue required for team success. For decision-making teams, a transactive memory system (TMS) offers team members a map of specialized knowledge, indicating source of knowledge and the source's credibility. SMM and TMS formulations aid human-agent team performance in their intended team types. However, neither improve team performance with a project team--one that requires both behavioral and knowledge integration. We present a hybrid cognitive model (HCM) …

B-Vitamins Influence The Consumption Of Macronutrients In Honey Bees, Walaa Ahmed Elsayeh, Chelsea N. Cook, Geraldine A. Wright

Biological Sciences Faculty Research and Publications

Insects require dietary sources of B-vitamins, but relatively little is known about whether they regulate B-vitamin intake in the same way they regulate other nutrients. Honey bees meet their B-vitamin requirements mainly from the pollen they collect. Employing the geometric framework for nutrition, we found that honey bees actively regulate their vitamin intake following Bertrand’s rule. We fed bees with a diet of essential amino acids (EAAs) and carbohydrate (C) to identify how the addition of B-vitamins affected the regulation of these macronutrients. In our experiments, honey bees preferred vitamins in concentrations comparable to those found in honey bee food …

Burnout In Pediatric Nephrology Fellows And Faculty: Lessons From The Sustainable Pediatric Nephrology Workforce Project (Superpower)., Susan M. Halbach, Kartik Pillutla, Patricia Seo-Mayer, Alan Schwartz, Darcy K. Weidemann, John D. Mahan

Manuscripts, Articles, Book Chapters and Other Papers

Physician well-being is an important contributor to both job satisfaction and patient outcomes. Rates of burnout among physicians vary by specialty, ranging from 35 to 70%. Among pediatric residents, longitudinal data demonstrates consistent rates of burnout around 50-60%, although little is known about burnout among pediatric subspecialty fellows. Specifically, the degree of burnout among pediatric nephrologists remains unknown, as does the impact faculty burnout may have on trainee burnout. We sought to evaluate prevalence and predictors of burnout among US pediatric nephrology fellows and faculty, and assess for interactions between groups. In this multi-center pilot survey of all United States …

I, Object, Shanee Gordon

Theses

I, Object is a 3D animated film which dives into the difference between intrinsic value and perceived value, both by an individual and by society, through an anthropomorphized world where household objects must do what they can to survive the onslaught of a depressed, do-it-yourself, divorcee. Following the mockumentary format, these objects are interviewed about the situation they find themselves in. The different personalities and dynamics between the characters brings a comedic element to an otherwise serious encounter. Opening with how the situation has progressed until the moment the filming crew arrived, the film jumps between characters but sticks to …

Comparison Of Clinical Outcomes Following Osteochondral Allograft Transplantation For Osteochondral Versus Chondral Defects In The Knee, John Reza Matthews, Joseph Brutico, Jeremy Heard, Kashyap Chauhan, Bradford Tucker, Kevin Freedman

Rothman Institute Papers

Purpose: Osteochondral allograft (OCA) transplantation is a restorative technique for addressing articular cartilage defects by transferring mature viable chondrocytes with subchondral bone into size-matched lesions. The purpose of this study was to compare differences in clinical and functional outcomes in patients treated with OCA for osteochondral defects compared with isolated chondral pathology.

Methods: A retrospective review identified patients who underwent OCA transplantation and grouped them into osteochondral or isolated chondral pathology. Demographic data, surgical history, lesion characteristics, complications, and rate of subsequent surgery were reviewed. The review included 86 patients (24 osteochondral, 62 chondral) with a mean follow-up of 5.4 …
