It has been informed by research carried out in 2022–2023 by the University of Plymouth and Southern Horizons (UK) Ltd following a mass shooting in Keyham, a small neighbourhood in the city of Plymouth, UK. The research was an independent evaluation of the community policing, community safety initiatives, and victim support services that were put in place in the area in the months after the incident.The College of Policing (2017) defines a major incident as “an event or …

Effect Of Biological Variation In Hba1c And Blood Glucose On The Diagnosis Of Prediabetes, James M. Hempe, Shengping Yang, Daniel S. Hsia

School of Medicine Faculty Publications

Introduction: People with a low or high haemoglobin glycation index (HGI) have lower or higher HbA1c than other people with the same FPG. This study compared the prevalence of prediabetes based on FPG, 2hOGTT and HbA1c in people with low, moderate or high HGI. Methods: Prediabetes was diagnosed based on ADA cutpoints in 10,488 NHANES participants without self-reported diabetes. HGI was calculated as the difference between a participant's observed HbA1c and a predicted HbA1c where predicted HbA1c = 0.024 FPG + 3.1. Participants were divided into low (HGI < −0.15%), moderate (HGI −0.15% to +0.15%) and high (HGI > +0.15%) HGI subgroups. Results: The prevalence of prediabetes was 42.4% based on …

The Role Of Central Amygdala Astrocytes In Ethanol Dependence, Todd Nentwig

MUSC Theses and Dissertations

Dependence is a hallmark of alcohol use disorder characterized by excessive alcohol intake and negative withdrawal symptoms. The central nucleus of the amygdala (CeA) is a key brain structure necessary for synaptic and behavioral consequences of ethanol dependence. Accumulating evidence suggests that astrocytes regulate synaptic transmission and behavior, however, a lack a basic understanding of the role of astrocytes in ethanol dependence. Therefore, the following experiments examined the effects of chronic intermittent ethanol (CIE) exposure on astrocyte-neuron interactions in the CeA. Astrocytes, the synaptic marker, synaptojanin1 (SJ1), and astrocytic GABA transporter, GAT3, were immunolabeled and analyzed using super-resolution confocal microscopy …

Examining The “Medicare Effect” On Distant-Stage Cancer Diagnoses By Site, Gender, And Rurality, Jason Semprini

Public Health

Background: Compared to cancers detected early, distant stage cancers are associated with lower survival, diminished quality of life, and higher costs. Evidence suggests that greater access to comprehensive health insurance (i.e., Medicare) improved early detection. Yet, few studies have evaluated the effect of Medicare coverage across cancers or factors influencing healthcare use.

Methods: This study analyzed 35 years of population-based cancer registry data from the Surveillance Epidemiology and End Results program for eight common cancers: Oral, Digestive, Respiratory, Skin, Genital, Urinary, Endocrine, and Breast. Leveraging the subjective threshold determining Medicare’s eligibility at age 65, Medicare’s effect on the probability of …

On The Economics Of The Transition To A Circular Economy, Ahmed Chennak, Konstantinos Giannakas, Tala Awada

Department of Agricultural Economics: Faculty Publications

Humanity is facing complex challenges posed by population growth, climate change, and the need to increase food, feed, fiber, and bioenergy production while confronting the scarcity of natural resources. The transition to a circular economy, characterized by reduced resource use and waste, is being increasingly recognized in academic, business, and policy making circles as essential to meeting these challenges, with the emphasis being on the development of methods and processes that enable and facilitate the transition from a linear to a circular economy. This paper argues the need for an increased emphasis on the economics of the circular economy and …

Exploring The Relationships Between Mammalian Functional Trait Distributions And Regional Biomes, With Application To Miocene Paleoecology, Devra Hock-Reid

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Paleoecology relies on understanding relationships between modern animals and their environment. Animals are adapted to niches in their environments, and those physical adaptations, or functional traits, are utilized as proxies to interpret aspects of paleo-ecosystems. Much is known about individual functional traits in extant mammals and their relationship to the environment. Less is known about how multiple functional traits across a community can be utilized for paleoecological interpretations. I develop models utilizing traits in mammalian communities at the biome level. For Chapter 1, I build a model for North American regional biomes using mammalian trait frequencies. I quantify changes in …

Scalable Production Of Peptides For Enhanced Struvite Formation Via Expression On The Surface Of Genetically Engineered Microbes, Jacob D. Hostert, Quincy A. Spitzer, Paola Giammattei, Julie N. Renner

Faculty Scholarship

A promising method for recycling phosphate from wastewater is through precipitation of struvite (MgNH4PO4·6H2O), a slow-release fertilizer. Peptides have been shown to increase the yield of struvite formation, but producing peptides via solid phase synthesis is cost prohibitive. This work investigates the effects of peptide-expressing bacteria on struvite precipitation to provide a sustainable and cost-efficient means to enhance struvite precipitation. A peptide known for increased struvite yield was expressed on a membrane protein in Escherichia coli(E. coli), and then 5 mL precipitation reactions were performed in 50 mL culture tubes for at least 15 min. The yield of struvite crystals …

Differential Expression Of Genes Involved In The Chronic Response To Intracortical Microelectrodes, Sydney S. Song, Lindsey N. Druschel, E. Ricky Chan, Jeffrey R. Capadona

Faculty Scholarship

Brain-Machine Interface systems (BMIs) are clinically valuable devices that can provide functional restoration for patients with spinal cord injury or improved integration for patients requiring prostheses. Intracortical microelectrodes can record neuronal action potentials at a resolution necessary for precisely controlling BMIs. However, intracortical microelectrodes have a demonstrated history of progressive decline in the recording performance with time, inhibiting their usefulness. One major contributor to decreased performance is the neuroinflammatory response to the implanted microelectrodes. The neuroinflammatory response can lead to neurodegeneration and the formation of a glial scar at the implant site. Historically, histological imaging of relatively few known cellular …

Analyzing The Continuum Of Control And Freedom In Intimate Relationships: A Grounded Theory, Daniel Smedley

Theses and Dissertations

Although research identifying and addressing extreme forms of control exists, all relationships experience some amount of control and some amount of the opposite of control, which is freedom. Large gaps in prevalence estimates and varied definitions of control suggest a need to better define the spectrum of control from mild to extreme forms, including looking at non-physically violent forms of coercive control. The purpose of this study was to expand knowledge of control in intimate relationships by examining the continuum of mild and extreme experiences of both control and freedom. Using constructivist grounded theory methods, the two categories of control …

Within-Store Fast Food Marketing: The Association Between Food Swamps And Unhealthy Advertisement, Curtis Jalen Antrum, Molly E. Waring, Juliana Cohen, Kristen Cooksey Stowers

Health Sciences Faculty Publications

Previous studies have linked food consumption outside the home and fast food to poor diet quality and living within a food swamp to an increased likelihood of obesity. A growing amount of research has linked food marketing to food choice. Still, limited information is available on how this dynamic may work within fast food establishments and if the marketing strategies used may vary by neighborhood food swamp status. Utilizing the Environment Assessment (EAT) Tool, we examined the within-store marketing environment of fast food restaurants to understand the factors potentially influencing food choice. A cross-sectional study design surveyed fast food outlets …

Securely Ever After: Attachment,Trust, And Commitment In Married Adult Adoptees, Jill P. Burgon

Theses and Dissertations

Past research suggests that adoptees face a higher risk of insecure attachment and encounter more challenges related to trust and commitment in their romantic relationships compared to nonadopted individuals. This study examines the association between adoption status and marital security among newly married couples, with a focus on the potential moderating role of gender. Using data from a representative sample of newly married couples in the United States (n = 2,110), the relationship between adoption status and multiple measures of marital security were measured using OLS regression. Findings indicate that, during the early stages of marriage, adult adoptees exhibited comparable …

Practicing Mathematics Teachers' Perspectives Of Public Records In Their Classrooms, Sini Nicole White Graff

Theses and Dissertations

While media displays exist in every mathematics classroom, these displays may have been taken for granted by teachers and researchers in terms of their potential use and impact on learning. This study looks at how three practicing mathematics teachers with differing teaching styles and experience levels view and use these media displays in their classrooms. This research shows how the relationship between a teachers' perceptions of media displays for showing mathematics are closely tied to their own beliefs regarding teaching and learning. Findings for this study can provide researchers with a starting place to see how teachers perceive and talk …

Exfoliation And Spray Deposition Of Graphene Nanoplatelets In Ethyl Acetate And Acetone: Implications For Additive Manufacturing Of Low-Cost Electrodes And Heat Sinks, Muhammed Ramazan Oduncu, Zhifan Ke, Bingyuan Zhao, Zhongxia Shang, Robin Simpson, Haiyan Wang, Alexander Wei

Department of Chemistry Faculty Publications

Nonaqueous dispersions of graphene nanoplatelets (GrNPs) can be used to prepare thin films and coatings free of surfactants, but typically involve polar organic solvents with high boiling points and low exposure limits. Here, we describe the mechanochemical exfoliation and dispersion of GrNPs in volatile aprotic solvents such as ethyl acetate (EtOAc) and acetone, which rank favorably in green solvent selection guides. GrNPs in powder form were exfoliated with a solvent on a horizontal ball mill for 48 h and then sonicated at moderate power to produce suspensions in excess of 300 μg/mL with minimum loss of dispersion stability over 7 …

Rift-Induced Disruption Of Cratonic Keels Drives Kimberlite Volcanism, Thomas M. Gernon, Stephen M. Jones, Sascha Brune, Thea K. Hincks, Martin Palmer, John C. Schumacher, Rebecca M. Primiceri, Matthew Field, William L. Griffin, Suzanne Y. O'Reilly, Derek Keir, Christopher J. Spencer, Andrew S. Merdith, Anne Glerum

Geology Faculty Publications and Presentations

Kimberlites are volatile-rich, occasionally diamond-bearing magmas that have erupted explosively at Earth’s surface in the geologic past^1,2,3. These enigmatic magmas, originating from depths exceeding 150 km in Earth’s mantle¹, occur in stable cratons and in pulses broadly synchronous with supercontinent cyclicity⁴. Whether their mobilization is driven by mantle plumes⁵ or by mechanical weakening of cratonic lithosphere^4,6 remains unclear. Here we show that most kimberlites spanning the past billion years erupted about 30 million years (Myr) after continental breakup, suggesting an association with rifting processes. Our dynamical …

Understanding Formation And Roles Of Niᴵᴵ Aryl Amido And Niiii Aryl Amido Intermediates In Ni-Catalyzed Electrochemical Aryl Amination Reactions, Jian Luo, Michael T. Davenport, Chad Callister, Shelley D. Minteer, Daniel H. Ess, T. Leo Liu

Chemistry Faculty Research & Creative Works

Ni-catalyzed electrochemical aryl amination (e-amination) is an attractive, emerging approach to building C-N bonds. Here, we report in-depth experimental and computational studies that examined the mechanism of Ni-catalyzed e-amination reactions. Key NiII-amine dibromide and NiII aryl amido intermediates were chemically synthesized and characterized. the combination of experiments and DFT calculations suggest (1) there is coordination of an amine to the NiII catalyst before the cathodic reduction and oxidative addition steps, (2) a stable NiII aryl amido intermediate is produced from the cathodic half-reaction, a critical step in controlling the selectivity between cross-coupling and undesired homo-coupling reaction pathways, (3) the diazabicycloundecene …

Targeted Muscle Reinnervation To Reduce Postoperative Pain In Patients Undergoing Hindquarter Resections, Mikaela H. Sullivan, Gavin L. Mills, Hiba Saifuddin, Elyse J. Brinkman, Brian T. Carlsen, Steven L. Moran, Matthew T. Houdek

School of Medicine Faculty Publications

Background/Aim: Pre-emptive targeted muscle reinnervation (TMR) at the time of amputation results in less phantom limb pain (PLP) compared with untreated amputee controls. There is limited literature describing the technique in patients undergoing hindquarter amputation despite up to 90% of these patients reporting PLP and 50% presenting with painful neuroma. The purpose of the current study was to describe the motor nerves accessible through a primary hind-quarter amputation to be used for TMR and review pain outcomes in clinical case correlates of patients with TMR. Patients and Methods: Six limbs were obtained from three fresh adult cadavers and proximal sensory …

Abaloparatide Maintains Normal Rat Blood Calcium Level In Part Via 1,25-Dihydroxyvitamin D/Osteocalcin Signaling Pathway, Yanmei Yang, Wei-Ju Louis Tseng, Bin Wang

Center for Translational Medicine Faculty Papers

The PTH-related peptide(1-34) analog, abaloparatide (ABL), is the second anabolic drug available for the treatment of osteoporosis. Previous research demonstrated that ABL had a potent anabolic effect but caused hypercalcemia at a significantly lower rate. However, the mechanism by which ABL maintains the stability of blood calcium levels remains poorly understood. Our in vivo data showed that ABL treatment (40 µg/kg/day for 7 days) significantly increased rat blood level of 1,25-dihydroxyvitamin D [1,25-(OH)2D] without raising the blood calcium value. ABL also significantly augmented the carboxylated osteocalcin (Gla-Ocn) in the blood and bone that is synthesized by osteoblasts, and increased noncarboxylated …

Morphological And Electrical Variance In Polysilicon Thin Film Transistors Crystallized By Flash Lamp Annealing, Glenn Packard

Theses

This work is a wide-reaching study of the factors that impact the in-situ crystallization of thin films of amorphous silicon into low-temperature polycrystalline silicon (LTPS) by flash lamp annealing (FLA) on glass substrates, which is used to develop thin film transistors (TFTs) with an eye towards display applications. The body of research surrounding FLA LTPS is thus advanced by identifying several challenges towards industrial integration and exploring solutions involving device configuration, novel methods of dopant introduction and activation, and novel TFT material systems. It is unlikely that FLA will ever produce LTPS superior to the laser-annealing techniques currently dominating the …

How Do Digital Advertising Auctions Impact Product Prices?, Alessandro Bonatti, Dirk Bergemann, Nicholas Wu

Cowles Foundation Discussion Papers

We ask how the advertising mechanisms of digital platforms impact product prices. We present a model that integrates three fundamental features of digital advertising markets: (i) advertisers can reach customers on and off-platform, (ii) additional data enhances the value of matching advertisers and consumers, and (iii) bidding follows auction-like mechanisms. We compare data-augmented auctions, which leverage the platform’s data advantage to improve match quality, with managed campaign mechanisms, where advertisers’ budgets are transformed into personalized matches and prices through auto-bidding algorithms. In data-augmented second-price auctions, advertisers increase off-platform product prices to boost their competitiveness on-platform. This leads to socially efficient …
