Identifying Daily Oil Market Shocks: Evidence From The Hormuz Crisis, Davide Valenti Dr., Chiara Casoli, Matteo Manera, Luca Pedini

Fondazione Eni Enrico Mattei Working Papers

This paper develops a daily Bayesian structural VAR model of the global crude oil market that decomposes the real price of oil into three fundamental drivers: shocks to global real economic activity, shocks to oil price expectations and shocks to physical oil supply. We combine a daily sign-restriction identification strategy with a posterior filtering step based on monthly physical oil market data, which sharpens the economic interpretation of the estimated daily shocks. We apply the model to provide a real-time interpretation of the main drivers behind the 2026 Strait of Hormuz crisis, one of the largest and most abrupt oil …

Ionophore-Based Plga Nanosensor For Selective Ion Detection And Imaging, Zhiyu Tang

Electronic Theses and Dissertations 2020 - Present

Accurate detection of electrolyte ions is essential for biological research, disease diagnosis, and the investigation of cellular function. In this study, we developed ionophore-based PLGA nanosensors for the optical detection of biologically important ions. The nanosensors were prepared by encapsulating ionophores, chromoionophore III, and ion exchangers within PLGA nanoparticles. The resulting nanosensors showed uniform morphology, good colloidal stability, and concentration-dependent optical responses toward Na⁺, K⁺, and Ca²⁺ over the range of 10⁻⁶ to 10⁻¹ M. Reversible fluorescence responses under repeated ion concentration changes confirmed the stability and robustness of the sensors. The nanosensors also demonstrated reliable analytical performance for K⁺ …

Load Balancing Algorithms For Cloud Computing Systems, Mark Rakesh Christian

Electronic Theses and Dissertations 2020 - Present

Cloud computing depends on load balancing to allocate user requests among virtual machines (VMs), affecting response time, utilization, and scalability. Round Robin, Equally Spread Current Execution, and standard Throttled scheduling are widely used; however, standard Throttled selects among eligible VMs using an implementation-dependent order with no explicit preference. This thesis proposes the Weighted Throttled Load Balancing (WTLB) algorithm, which introduces an explicit, deterministic selection priority among eligible VMs, implemented by modifying the Throttled scheduler within CloudAnalyst.

Evaluated under an identical six-region, multi-data-center configuration against Round Robin, ESCE, and standard Throttled, WTLB preserves the aggregate response-time, processing-time, and cost profile of …

Using Temporal Genomic Data To Uncover Patterns Of Genetic Diversity And Signatures Of Selection For Management Of A Threatened Minnow Species, Erika A. Dunn

Biology ETDs

The Little Colorado River (LCR) spinedace persists only in three isolated watersheds within the LCR Basin in Arizona. This imperiled minnow faces ongoing pressure from habitat alteration, climatic shifts, and invasive non-native predators. Over the past two decades, managers have translocated spinedace within watersheds to increase abundance and expand habitat occupancy. We sequenced a reference genome and analyzed single nucleotide polymorphisms (SNPs) from 475 individuals over their geographic range. DNA samples were obtained from a previous study in the mid-1990s and compared with samples from 2024 and 2025, allowing us to track genetic diversity, effective population size, population structure, and …

Finding Fish Families: Movement And Demography Of Loach Minnow (Tiaroga Cobitis) Inferred From Gt-Seq-Enabled Kinship Analysis, Patrick C. Baca

Biology ETDs

River fragmentation poses major threats to freshwater biodiversity by reducing connectivity and limiting persistence of imperiled desert fishes. Connectivity in streams is impaired by anthropogenic changes, including road crossings, prompting the installation of engineered fish passage structures at low-water road crossings and raising questions about the dispersal of aquatic species across these structures. This thesis investigates the movement of the threatened Loach Minnow (Tiaroga cobitis) by applying a close-kin mark-recapture (CKMR) framework in a restored stream (including a fish passage) and a stream without rehabilitation efforts. We developed and optimized a GT-seq panel for relatedness analysis and used it to …

Speech and Hearing Sciences ETDs

ABSTRACT

This dissertation examined aided AAC interventions for individuals with multiple disabilities, including visual impairment, across three original studies. Chapter 2, a meta-analysis, found limited rigorous research for this population while showing that individuals at early symbolic stages with diverse visual profiles can successfully engage with AAC when appropriate adaptations are provided. The pilot study in Chapter 3 indicated that caregivers and graduate student clinicians can learn and implement naturalistic AAC techniques and VI accommodations with high fidelity through structured coaching. The mixed methods study in Chapter 4 introduced the ImPAACT-VI program, showing strong outcomes in educator performance, students’ symbolic …

Recovery Through Connection: The Role Of Positive Social Interactions In Early Alcohol And Opioid Recovery Outcomes, Hannah Avery Carlon

Psychology ETDs

Recovery from substance use disorder (SUD) is influenced by both positive emotional functioning and social connectedness. However, empirical research has yet to examine how these two protective factors interact to influence recovery. The present study aimed to address this gap by exploring positivity resonance, or the shared experience of positive emotions, in the first year of recovery. In Aim 1, we examined change trajectories of positivity resonance and recovery capital over the first year of recovery among adults with alcohol use disorder (AUD; n=470) and opioid use disorder (OUD; n=61), the associations between these change trajectories (1a), and …

Understanding The Long-Run Effect Of Historical Redlining Practices, Yujian Lu

Geography ETDs

Historical redlining practices initiated by Home Owners’ Loan Corporation (HOLC) in the 1930s have produced enduring persistent socioeconomic and environmental disparities in U.S. cities. This dissertation examines their long-term impacts on social vulnerability, urban flood risk, along with public discourse about redlining practices. Results indicate that neighborhoods with HOLC grade A (greenlined) exhibit the lowest overall social vulnerability, while those graded D (redlined) face the highest across U.S. cities. In Chicago, associations between redlining practices and flood risk disparities are stronger than in Los Angeles, reflecting place-specific characteristics among environmental, socioeconomic, and demographic factors shaping flood risk disparities in long …

How Forest Structure And Climate Influence Snowpack For Water Resources In The Southwestern United States, Lindsey L. Rotche

Geography ETDs

Climate change, declining snowpack, and increasing wildfire risk have profound impacts on water availability in the southwestern United States. Because the southwestern United States is a global hotspot for freshwater vulnerability, and snowpack provides much of the region’s freshwater, understanding how climate and forest structure influence snowpack dynamics is increasingly important. In this dissertation I aim to better understand and communicate these dynamics through empirical data collection and the development of a simple vegetation driven temperature-index snow model: SNOW-17(VEG). I then implement the model at a watershed scale using remotely sensed imagery to create vegetation zones and climate simulations to …

Reading The Martian Surface: Impact Crater Distributions And Geochemical Signatures In Gale Crater As Recorded By The Curiosity Rover, Megan E. Hoffman

Earth and Planetary Sciences ETDs

The Curiosity rover has been exploring Gale crater, a large impact basin near the Mars equator since 2012. This mission has greatly improved our ability to explore the surface of Mars with a suite of geologic tools and cameras and has revealed that Mars likely once resembled present-day Earth. In this dissertation, I utilize measurements and data taken by Curiosity to analyze the distribution and preservation of small impact craters at meter scales, I quantify the formation characteristics of a small impact crater cluster, and I examine the presence of barium in a geologic unit with high-Si to constrain sediment …

Mitigating Cancer Therapy-Related Cognitive Impairment By Targeted Activation Of Undruggable Phosphatase., Zhimeng Yao, Yuhua Meng, Huanyi Li, Yinhui Jiang, Xiaona Lin, Mengyuan Hu, Qing Liu, Xiaofu Qiu, Hongzheng Ren, Yunlong Pan, Bin Pan, Zexiong Guo, Shuyao Zhang, Dianzheng Zhang, Li Yang, Shegan Gao, Weijing Deng, Jianfan Chen, Hao Zhang

PCOM Scholarly Works

Cancer therapy-related cognitive impairment (CTRCI) is a debilitating neurotoxic condition adversely impacting cancer patients during and post-cancer treatments. The cancer treatments linked to CTRCI include chemotherapy, hormone therapy, targeted therapy, and immunotherapy. Despite CTRCI severely affecting the psychological and social, cognitive functions, and the overall quality of life of cancer survivors, no effective medications are available currently. Our prior studies have indicated hippocampal tyrosine phosphatase protein tyrosine phosphatase receptor type O (PTPRO) as a putative target for CTRCI. However, phosphatase is historically considered undruggable, and delivering drugs across the blood-brain barrier (BBB) is challenging. Here, we developed a novel delivery …

Under Pressure: Negative Urgency And Disordered Eating In The Context Of Parental Differential Support, Hamide Gozu, Jenna K. Rieder

College of Humanities and Sciences Faculty Papers

Disordered eating behaviors are prevalent in emerging adulthood and may be shaped by family dynamics. This study examined associations among maternal and paternal differential support, weight-shape concerns, and binge eating and compensatory behaviors in emerging adulthood, while testing the moderating role of negative urgency. Participants were 517 emerging adults from across the United States (ages 18-29; M = 22.60, SD = 3.81; 76% female). Participants reported on parental differential support, weight-shape concerns, eating behaviors, and negative urgency. Using moderated-mediation analyses, we found that weight-shape concerns mediated associations between differential support and eating behaviors. Unequal maternal support and paternal favoritism showed …

Understanding The Mechanisms Behind Increased Load Transfer In Bmi-Flcnt Composites Using Molecular Dynamics, Swapnil S. Bamane, Prathamesh P. Deshpande, Aowabin Rahman, Ashley D. Spear, Gregory Odegard

Michigan Tech Publications

Crewed deep-space exploration is a future milestone for the aerospace industry. Such aerospace missions demand ultrastrong, lightweight structural materials to minimize the payload mass. Polymer matrix composites (PMCs) with carbon-based reinforcements, such as carbon fiber, graphene, and carbon nanotubes (CNTs), are of primary interest as structural materials for these applications. Although PMCs are lightweight and strong, their mechanical performance is limited to the weak interface region. The interface region can be strengthened by chemical functionalization of the reinforcement materials and covalent cross-linking of the matrix and the reinforcement. Molecular dynamics (MD) offers a platform for computationally investigating the effects of …

Improving Outpatient Provider Preparedness Through Simulation-Based Training: A Quality Improvement Project, Kristina Weyer

DNP Projects

Introduction:
Simulation-based training is an effective educational strategy, particularly for high-acuity, low-frequency events such as patient decompensation in outpatient settings. However, there is a gap in both literature and practice regarding provider participation in simulation, as competing clinical demands often limit engagement. Local organizational leaders identified limited opportunities for outpatient providers to practice management of acute decompensating patients. The purpose of this project was to evaluate provider competence and confidence in managing a decompensating patient in the outpatient setting and to assess perceptions of the value of time spent in simulation.

Methods:
This quality improvement project evaluated providers who participated …

Targeted Nursing Bootcamps For Critical Access Hospital Nurses: A Program Evaluation., Nicholas Popp

DNP Projects

Background: Registered Nurses employed in critical access hospital settings are required to care for patients across the lifespan with varying levels of acuity. The registered nurse (RN) must be competent in providing medical, surgical, pediatric, obstetric, and intensive care-level services. However, the additional training they receive to care for their patients may be minimal or nonexistent, leading them to seek employment at other facilities due to safety concerns. Leadership within the organization believed that implementing targeted monthly nursing skills boot camps could increase nurses’ competence, confidence, and retention in critical access hospital settings.

Aims: This program evaluation project aimed to …

Genocide In Gaza? Social Media Discussions Of Violence In Israel And Gaza, Timothy Williams, Andreas Dafnos

Genocide Studies and Prevention: An International Journal

This article conducts social network and topic analyses of German-language posts on X that discuss genocide and terrorism in Israel and Gaza in the first six months after the October 7 attacks and compares these to broader English-language discourses on the platform. The comparison reveals subtle differences in how Israeli violence and governance and Palestinians are discussed and who is seen as complicit in supporting violence. Markedly, German-language posts discuss what constitutes antisemitism more and employ a more restrained language towards Israel as a state and its political actors than English-language posts. We tie these findings back to the idiosyncrasies …

Genocidal Criminology: My Testimony, Yarin Eski

Genocide Studies and Prevention: An International Journal

This article is a testimony on the entanglement of my personal biography, responsibility, and lived experience of genocide denial and, subsequently, developing criminologies of genocide and its denial, based on my formative experiences, ranging from encountering Armenian genocide denial as a student, to dealing with institutional constraints and careerism, to my academic activism, raising awareness about the Gaza genocide, to, finally, prospecting genocide and ecocide in outer space: astrocide. These experiences configure a genealogy of what I term genocidal criminology that unpacks and criticizes criminological knowledge, institutions, and practices that produce genocide (denial), both epistemically and structurally. Essentially, I argue …

Evaluating Preoperative Education Modalities For Orthopedic Surgery Patients, Hannah Johnson

DNP Projects

Effective preoperative education is essential as total joint arthroplasty (TJA) procedures shift to outpatient care, yet traditional education methods may not be meeting patients’ diverse learning styles. This Doctor of Nursing Practice (DNP) project aimed to evaluate the impact of multimodal preoperative education (in-person, virtual, hybrid video modules, or a combination) on patient-reported anxiety and discharge readiness, as well as length of stay (LOS), surgical site infections (SSIs), and 30-day readmissions. The in-person portion could not be implemented due to staffing constraints. The pre-post evaluation was conducted with a sample of 273 patients undergoing elective hip and knee arthroplasty (pre …

Bridging The Gap: Empowering Primary Care Providers With Nonpharmalogical Strategies For Adhd Management, Grace Sawyer

DNP Projects

Attention-deficit/hyperactivity disorder (ADHD) affects many adults and children and is commonly managed with pharmaceutical drugs. Although evidence supports the use of nonpharmacological, many providers may not know or have the confidence to use these modalities to incorporate these into practice. This educational gap could contribute to an overreliance on medication when there are other options available for comprehensive ADHD care.  This quality improvement pretest-posttest design aimed to bridge the gap in provider knowledge and confidence regarding evidence-based nonpharmacological ADHD management at two college health clinics.  The intervention consisted of four pre-recorded modules delivered over four weeks that focused on exercise, …
