Synthesis Of Stimuli-Responsive Programmable Polymers Through Ring-Opening–Metathesis Cross-Metathesis (Rom-Cm), Courtney S. Dziewior, Sharon M. S. Strickland, Ping Li, Ken D. Shimizu

Journal of the South Carolina Academy of Science

Stimuli-responsive polymers can change their physical and/or chemical properties in response to external stimuli. These polymers have found great success in a number of important areas including molecular gels and biomedical engineering, as well as success in applications such as targeted drug delivery and biosensors. We have been working toward the development of programmable polymers that remember the response after a stimulus is withdrawn. To this end, we set out to synthesize specific functional monomers. While different types of reactions could potentially result in the desired target monomer, we studied the ring-opening metathesis–cross-metathesis reaction (ROM-CM). Previous work of ours synthesized …

The Effect Of Combination Birth Control Pills On Heart Rate, Blood Pressure, Body Weight And Body Temperature, Scarlett E. Leigh, Marlee B. Marsh

Journal of the South Carolina Academy of Science

Birth control pills are the most popular method of birth control for women. In the United States of America, roughly 10.2 million women use some type of birth control pills. The two main types of birth control pills available to women are combination pills, which contain both estrogen and progestin, and progestin-only birth control pills that do not contain any estrogen. Numerous biological research studies have been performed studying the effects of combination birth control pills on blood pressure and body weight. However, few studies have examined blood pressure combined with both heart rate, body temperature, and body weight to …

The Double-Edged Sword Of Diagnosis: Medical Neoliberalism In Rape Crisis Center Counseling, Shannon M. Peters Aug 2019

The Double-Edged Sword Of Diagnosis: Medical Neoliberalism In Rape Crisis Center Counseling, Shannon M. Peters

Graduate Doctoral Dissertations

The prevalence of sexual violence in the United States is a critical issue and the aftermath of sexual assault can have profound effects on psychological well-being. Rape Crisis Centers play a vital role in supporting sexual violence survivors. The framework through which Rape Crisis Center clinicians understand the experiences of survivors has a substantial impact on the course of counseling, how survivors interpret their own experiences, and survivors’ psychological health. A neoliberal medicalized framework conceptualizes distress post-sexual assault as a disease or disorder and places the responsibility on an individual to ‘fix’ themselves, situating the problem within the person, rather …

Demographic Assessment Of The Triploid Parthenogenetic Lizard Aspidoscelis Neotesselatus At The Northern Edge Of Its Range, Lise M. Aubry, Douglas Eifler, Kaera Utsumi, Susannah S. French

Biology Faculty Publications

Aspidoscelis neotesselatus (Colorado Checkered Whiptail) is a hybrid-derived triploid parthenogenetic lizard with a natural range overlapping with six counties in southeastern Colorado, USA. It has also become established by anthropogenic causation in Grant County, Washington State, approximately 1,600 km northwest of its range in Colorado. Large parts of its natural range are within military reservations. Reduced genetic variation in all-female species makes them especially susceptible to environmental disturbances, such as military activities. At Fort Carson (FC), we estimated an abundance index via a catch-per-unit estimator, weekly survival using Cormack-Jolly-Seber models, and body condition and clutch size as indicators of population …

Global Eras And Language Diversity In Indonesia: Transdisciplinary Projects Towards Language Maintenance And Revitalization, James T. Collins Aug 2019

Global Eras And Language Diversity In Indonesia: Transdisciplinary Projects Towards Language Maintenance And Revitalization, James T. Collins

Paradigma: Jurnal Kajian Budaya

Indonesia is immensely proud of its hundreds of regional languages. This amazing diversity occurs because of the social impact in the three global eras: ancient migration from Asian continent, trading intensification and colonial oppression five hundred years ago, and demographical and communication change in the 21st century. However, now we are witnessing the number decrease of the languages in Indonesia. The resistance and preservation of the inherited languages, which are local languages, in the Indonesian archipelago (Nusantara) language network that is indeed complex must be considered as important components in the Indonesia’s national identity. Along with the accelerated loss of …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Several infectious diseases are threatening amphibian species worldwide and have resulted in massmortality events across the globe. An emerging group of viral pathogens (ranaviruses) are documented to cause die-offs in amphibian populations worldwide, including in several regions of the U.S. Unfortunately, large gaps remain in our understanding of the distribution of this systemic pathogen in the U.S., including within the state of Oklahoma. To address this gap in our understanding, we carried out surveys of this infectious pathogen across 14 sites in seven southeastern Oklahoma counties in spring 2015, screening 17 amphibian species from this region.

Performance Assessment Practice As Professional Learning, Vanessa Svihla, Tim Kubik, Tori Stevens-Shauger Aug 2019

Performance Assessment Practice As Professional Learning, Vanessa Svihla, Tim Kubik, Tori Stevens-Shauger

Interdisciplinary Journal of Problem-Based Learning

While performance assessment (PA) is well aligned to project-based learning (PjBL), teachers find it challenging to design and implement PA that is faithful to the authentic context of their projects and viewed externally as rigorous. In contrast to standardizing PA tasks — thereby diminishing authenticity — we formed a research-practice partnership (Coburn, Penuel, & Geil, 2013) that developed and used a “shell” to guide teachers in planning, implementing, and engaging in rigorous dialogues that evaluate and elevate PA practice across four PjBL schools. Drawing from analysis of artifacts and audio-recorded professional development sessions, we highlight how the effort to standardize …

Theorizing About The Self In Panpsychism And The Extended Mind Using The Dao De Jing (道德經) And Zhuangzi (莊子), Ryan Lemasters Aug 2019

Theorizing About The Self In Panpsychism And The Extended Mind Using The Dao De Jing (道德經) And Zhuangzi (莊子), Ryan Lemasters

The Hilltop Review

In this paper, I begin by briefly showing how the problem of self has been understood and approached historically in Western philosophy. I follow this by focusing on some of the recent literature in the philosophy of mind that suggests that the self is extended, meaning it is not solely located within the boundaries of the brain (Clark and Chalmers 1998). It will be evident that this is in conflict with the traditional Western understanding of the self. Since it seems to be the case that there are strong arguments for endorsing the view that the self is extended (to …

Characterization And Optogenetic Manipulation Of The Affective Itch Circuit In Mouse Models Of Itch, Kristen Marie Sanders Aug 2019

Characterization And Optogenetic Manipulation Of The Affective Itch Circuit In Mouse Models Of Itch, Kristen Marie Sanders

Open Access Dissertations

Itch consists of both sensory and affective components. For chronic itch patients, the affective component of itch affects both quality of life (leading to psychological comorbidities) and disease prognosis (by promoting scratching of itchy skin). We found that acute and chronic itch stimuli induced anxiety-like behavior and increased activity (c-Fos expression) in the amygdala in adult male C57BL/6 mice. Itch stimuli also increased activity in projection areas to the amygdala, suggesting that these regions form a circuit for affective itch processing. Selective optogenetic activation of histamine-responsive amygdala neurons in adult male and female Fos:CreERT2;R26Ai14 mice using the …

Engineered nanoparticles are incorporated into numerous emerging technologies because of their unique physical and chemical properties. Many of these properties facilitate novel interactions, including both intentional and accidental effects on biological systems. Silver-containing particles are widely used as antimicrobial agents and recent evidence indicates that bacteria rapidly become resistant to these nanoparticles. Much less studied is the chronic exposure of bacteria to particles that were not designed to interact with microorganisms. For example, previous work has demonstrated that the lithium intercalated battery cathode nanosheet, nickel manganese cobalt oxide (NMC), is cytotoxic and causes a significant delay in growth of Shewanella …

Enzymatic Biofuel Cells In A Sandwich Geometry With Compressed Carbon Nanotubes/Enzyme Electrodes & Hybrid Patch Applications, Biao Leng Aug 2019

Enzymatic Biofuel Cells In A Sandwich Geometry With Compressed Carbon Nanotubes/Enzyme Electrodes & Hybrid Patch Applications, Biao Leng

Dissertations

Enzymatic biofuel cells (EBFCs) convert the chemical energy of biofuels, such as glucose and methanol, into electrical energy by employing enzymes as catalysts. In contrast to conventional fuel cells, EBFCs have a simple membrane-free fuel cell design due to the high catalytic specificity of the enzymes, but the power densities obtained are lower. Although the primary goal of research on EBFCs has been to develop a sustainable power source that can be directly implanted in the human body to power bio-devices, other applications such as the use of a flexible film or fuel cell patch as a wearable power source …

Mapping The Emotional Experience Of Travel To Understand Cycle-Transit User Behavior, Mahbubur Meenar, Bradley Flamm, Kevin Keenan

School of Earth & Environment Departmental Research

People experience emotions during travel. Driving, riding a bicycle, taking transit, and walking all involve multiple mental processes, potentially leading to various ranges of emotions such as fear, anger, sorrow, joy, and anticipation. Understanding the link between emotions and transportation environments is critical to planning efforts aiming to bring about a more environmentally sustainable society. In this paper, we identified, geo-coded, analyzed, and visualized emotions experienced by cycle–transit users, or CTUs, who combine bicycling and public transit in a single trip. We addressed two research questions: (1) What types of emotions do CTUs experience, why, and where? (2) How can …

Singlet fission is known to improve solar energy utilization by circumventing the Shockley-Queisser limit. The two essential steps of singlet fission are the formation of a correlated triplet pair and its subsequent quantum decoherence. However, the mechanisms of the triplet pair formation and decoherence still remain elusive. Here we examined both essential steps in single crystalline hexacene and discovered remarkable anisotropy of the overall singlet fission rate along different crystal axes. Since the triplet pair formation emerges on the same timescale along both crystal axes, the quantum decoherence is likely responsible for the directional anisotropy. The distinct quantum decoherence rates …

A Review And Updated Classification Of Pollen Gathering Behavior In Bees (Hymenoptera, Apoidea), Zachary M. Portman, Michael C. Orr, Terry Griswold Aug 2019

A Review And Updated Classification Of Pollen Gathering Behavior In Bees (Hymenoptera, Apoidea), Zachary M. Portman, Michael C. Orr, Terry Griswold

All PIRU Publications

Pollen is the primary protein and nutrient source for bees and they employ many different behaviors to gather it. Numerous terms have been coined to describe pollen gathering behaviors, creating confusion as many are not clearly-defined or overlap with existing terms. There is a need for a clear yet flexible classification that enables accurate, succinct descriptions of pollen gathering behaviors to enable meaningful discussion and comparison. Here, we classify the different pollen gathering behaviors into two main classes: active and incidental pollen collection. Active pollen collection is subdivided into six behaviors: scraping with the extremities, buzzing, rubbing with the body …

Aimee Semple Mcpherson’S Pentecostalism, Darwinism, Eugenics, The Disenfranchised, And The Scopes Monkey Trial, Margaret English De Alminana

Selected Faculty Publications

This article posits that the cultural battle waged by Aimee Semple McPherson in concert with William Jennings Bryan over evolution and modernism was largely focused on a popular social theory linked to eugenics. On July 21, 1925, in the city of Dayton, Tennessee, a twentieth-century watershed event became a harbinger of the age: The State of Tennessee v. John Thomas Scopes, popularly known as the Scopes Monkey Trial. The public remembers the event as spotlighting the fundamentalist-modernist controversy with respect to the teaching of evolution in the public-school curriculum against the protests of fundamentalist Christians who advocated Creationism.

Visual Discrimination, Serial Reversal, And Extinction Learning In The, Price E. Dickson, Guy Mittleman

Faculty Research 2019

Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy and the most common neuromuscular disorder. In addition to neuromuscular consequences, some individuals with DMD experience global intellectual dysfunction and executive dysfunction of unknown mechanistic origin. The cognitive profile of the mdx mouse, the most commonly used mouse model of DMD, has been incompletely characterized and has never been assessed using the touchscreen operant conditioning paradigm. The touchscreen paradigm allows the use of protocols that are virtually identical to those used in human cognitive testing and may, therefore, provide the most translational paradigm for quantifying mouse cognitive function. …

Controls And Adaptive Management Of Nitrification In Agricultural Soils, Jeanette M. Norton, Yang Ouyang Aug 2019

Controls And Adaptive Management Of Nitrification In Agricultural Soils, Jeanette M. Norton, Yang Ouyang

Plants, Soils, and Climate Faculty Publications

Agriculture is responsible for over half of the input of reactive nitrogen (N) to terrestrial systems; however improving N availability remains the primary management technique to increase crop yields in most regions. In the majority of agricultural soils, ammonium is rapidly converted to nitrate by nitrification, which increases the mobility of N through the soil matrix, strongly influencing N retention in the system. Decreasing nitrification through management is desirable to decrease N losses and increase N fertilizer use efficiency. We review the controlling factors on the rate and extent of nitrification in agricultural soils from temperate regions including substrate supply, …
