Age Reassignment Using Luminescence Dating For The Mammoth Site, Black Hills, South Dakota, Usa, Shannon A. Mahan, Jim I. Mead, P.R. Hanson, Emma T. Krolczyk, Christopher N. Jass

School of Natural Resources: Faculty Publications

The Mammoth Site (MS) at Hot Springs, South Dakota, provides a unique opportunity to reconstruct paleoenvironmental conditions on the Northern Great Plains of the United States. Previous radiocarbon analyses of mammoth bone apatite suggested the MS sinkhole was deposited ∼42–23 cal ka BP. However, two U-series ages and one thermoluminescence (TL) age ranged between 150 and 101 ka, suggesting the bones were considerably older. We analyzed six samples from the bone bed using infrared-stimulated luminescence (IRSL) on feldspars, because the quartz luminescence was saturated; the ages ranged from approximately 232 to 160 ka, showing better agreement with previous U-series and …

Stemless Arthroplasty For Avascular Necrosis Of The Humerus: Implant Survival And Outcomes, Alyssa R. Henriquez, Damon V. Briggs, Eoghan T. Hurley, Samuel Lorentz, Christopher S. Klifto, Michael A. Moverman, Oke Anakwenze

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Avascular necrosis (AVN) of the humeral head often affects younger patients and may lead to progressive pain and functional deficits. While stemmed hemiarthroplasty and total shoulder arthroplasty (TSA) are established treatments for advanced-stage AVN, stemless arthroplasty offers potential advantages including bone preservation and facilitation of future revision. However, the impact of bone necrosis on stemless humerus fixation is yet to be elucidated. Therefore, the purpose of this study was to evaluate the outcomes of stemless hemiarthroplasty and TSA in treating humeral head AVN and, further, to determine if stemless humeral fixation is appropriate in this population.

Identifying The Brain Circuits Involved In Religious Obsessive-Compulsive Disorder, Kiana Bunnell

Theses and Dissertations

Obsessive-compulsive disorder (OCD) is an often-debilitating psychiatric disorder involving a pattern of obsessive thoughts and compensatory compulsions. Symptoms tend to be chronic, leading to substantial emotional burden and significant impairment across multiple domains of daily functioning. Previous research has identified some consistency in the brain regions implicated in OCD. In particular, cortico-striato-thalamo-cortical (CSTC) circuitry has been linked to behavioral features commonly observed in OCD. Moreover, some studies suggest that distinct patterns of brain activation and functional connectivity may be associated with different OCD symptom dimensions, though findings have not been consistent. One symptom dimension of OCD (scrupulosity) is characterized by …

Is “No Change” Really No Change?: A Qualitative Analysis Of Clients With “No Change” On Routine Outcome Monitoring Who Report Improving In Therapy, Audrey Louise Stewart Parker

Theses and Dissertations

Routine outcome monitoring (ROM), the practice of tracking client progress in therapy by administering regular questionnaires to assess functioning, has demonstrated a significant positive effect on psychotherapy outcomes, especially for clients are who not improving as expected. However, some researchers argue the symptom-based measures and outcome classification criteria commonly used in ROM may not represent a complete picture of client change. A recent body of mixed-methods research has investigated these ROM-determined outcome categories to gain insight into client experiences and whether the category and client perception of therapy outcome align. In this investigation, researchers have found significant variety within outcome …

An Interprofessional Organization Change Process To Reduce Catheter-Associated Urinary Tract Infections, Bolatito Owolabi

Walden Dissertations and Doctoral Studies

This organization change process initiative addressed a critical safety practice gap regarding catheter-associated urinary tract infection (CAUTI) prevention in a 450-bed acute care facility. This gap was recognized based on evidence that the facility’s CAUTI Standardized Infection Ratio (SIR) was above the national benchmark—and daily necessity assessment compliance of only approximately 50%. This gap was attributed to an organizational interprofessional culture, which hindered timely device removal. Prolonged catheter dwell times increase patient morbidity, extend hospital stays, and expose the organization to severe financial penalties. The project aimed to safely reduce device dwell times by structurally empowering bedside nurses. I used …

Effective Strategies To Implement Energy-Efficient Practices In Enterprise Cloud Data Centers: A Qualitative Pragmatic Inquiry, Joshua Tremayne Campbell

Walden Dissertations and Doctoral Studies

Cloud computing has increased electricity use in data centers, leading to higher costs and a larger carbon footprint. Information Technology (IT) leaders need to address this, as such inefficiencies will increase operational costs, undermine sustainability commitments, and leave companies unprepared for future regulatory pressures. Energy-efficient technologies can reduce data center energy consumption by 40-60%, yet few studies examine the qualitative processes behind IT leaders' practices. The specific IT problem is that some IT leaders lack effective strategies to implement energy-efficient practices in enterprise cloud data centers. Grounded in the technology-organization-environment (TOE) framework, the purpose of this qualitative pragmatic inquiry was …
