Predicting Single-Leg Eccentric Hamstrings Strength In Aging Athletes Using Diagnostic Ultrasound- And Survey-Derived Parameters, Lee J. Hinkle

Theses and Dissertations

Introduction: Eccentric hamstring strength declines with age and contributes to mobility limitations. Although Nordbord testing quantifies eccentric strength, few studies have examined it in older adults, and none have predicted strength performance on this test using ultrasound or survey- based measures. Methods: We recruited 122 senior athletes (60 female) at the 2024 Huntsman World Senior Games. Ultrasound-derived cross-sectional area (CSA), echogenicity, and subcutaneous fat thickness, along with demographic and activity data, were used to predict single-leg peak force using Bayesian regression. Models were sex-stratified, and predictors were selected using leave-one-out cross-validation (LOO IC). Results: In males, CSA, age, leg side, …

The Exaggerated Blood Pressure Response To Activities Of Daily Living And Exercise Is Dependent Upon The Fitness Of People With Hypertension, Joseph D. Larsen

Theses and Dissertations

Purpose: Determine if the previously reported exaggerated systolic blood pressure response to daily activity and moderate exercise amongst hypertensive adults could be accounted for by differences in fitness. Methods: 30 normotensives adults (15 low fitness control (LFC) and 15 high fitness control (HFC)) and 15 unmedicated adults with ambulatory hypertension (HTN) participated in this study. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Lactate Threshold (LT) and estimated ����̇O2max were determined for each participant. A week later, blood pressure was measured while participants completed 5-minute bouts of treadmill exercise at fixed absolute intensities (2.5 mph 0% and 12% grade) and …

A More Perfect Peace: Can The Russia-Ukraine War End Justly?, Nathaniel B. Davis, Marlon A. Thomas

The US Army War College Quarterly: Parameters

This article argues that thinking creatively about war termination, both philosophically and politically, utilizing jus post bellum principles and counterintuitive political trade-offs, reveals an opportunity to achieve a sustainable peace that approximates justice. The article surveys how war aims among belligerents have changed, indicating that further change is possible, particularly at the point of war termination. Next, the article examines jus post bellum principles and their application to the Russia-Ukraine War. Finally, the article contends that Ukraine relinquishing Crimea and the Donbas in exchange for NATO membership might be the key to achieving a durable peace that addresses long-term security.

Characterization Of Ultra-High-Speed Friction Stir Welds Made In Thin Sheet Aa6061-T4 Material, Todd Grant Lainhart

Theses and Dissertations

Friction stir lap welding (FSLW) of thin aluminum sheets in industry and in research has faced challenges in weld quality that limit welding speeds. Interfacial defects such as hooking and thinning are common defects that appear at the interface of FSLW, and researchers and process operators have traditionally reduced process parameters such as feed rate and spindle rotation to fully eliminate the defects. While such measures are successful in creating fully consolidated FSLW, feed rates for FSLW have stagnated around 1 mpm with the fastest feed rates recorded at 3 mpm, making it difficult for manufacturers to implement FSLW in …

China’S Role In A Future Korean War, Jake Rinaldi

The US Army War College Quarterly: Parameters

This article argues that China’s intervention in a Korean conflict will hinge more on North Korea’s ability to hold territory than on bilateral ties. Rather than treat Chinese intervention as a yes-or-no proposition, this study models three scenarios—full intervention, sustained support, and limited support—based on North Korean resilience. Using Chinese-language sources and scenario-based analysis, it assesses how each model would shape key functional areas such as ISR, cyber, materiel, and force posture. The findings offer US defense planners a framework for anticipating variable People’s Liberation Army involvement in a future Korea contingency.

The Next National Defense Strategy: Mission-Based Force Planning, Frank G. Hoffman

The US Army War College Quarterly: Parameters

The Pentagon needs to embrace a new methodology called mission-based planning to size and shape the defense enterprise properly. This article critiques several proposals for reestablishing the long-standing two major theater war construct in the face of ongoing shifts in the strategic environment, including the nation’s $36 trillion debt and prospects of annual interest payments beyond $1 trillion. It presents a mission priority alternative focused on strategic prioritization based on the authors’ four decades of experience in strategy/force planning at the service, the department, and the Office of the Secretary of Defense levels. Strategic-level service planners and students of Joint …

Computational Advances For Single-Cell Proteomics, Hannah Boekweg

Theses and Dissertations

The overarching goal of biologists is to characterize biological systems. When the workings of a system are understood, they can be fixed, broken, preserved, mimicked, and even replicated. The field of proteomics seeks to characterize systems through the lens of proteins. Proteins are referred to as the 'workhorse' of the cell to illustrate that they perform most functional tasks within the cell. These tasks are highly varied, including enzymatic activity, structural support, transport, storage, cell signaling, gene regulation, immune response, and more. Proteomics has been instrumental in new biological discoveries by characterizing the functional state of cells. A new area …

Tomato Seedling Performance In Five Commercial Organic Growing Media With And Without Supplemental Fertilizer, Elizabeth Maynard, Wenjing Guan, Petrus Langenhoven, Lori A. Hoagland

Department of Horticulture & Landscape Architecture Faculty Publications

Commercially available growing media permitted for use in certified organic production differ substantially in quantity and availability of essential macronutrients. Nutrient availability from fertilizers applied during production will depend on chemical, biological, and physical characteristics of both media and fertilizers; therefore, best practices for fertilizing seedlings are likely to differ. This study evaluated tomato (Solanum lycopersicum L.) emergence, seedling growth, and posttransplant performance when grown in five organic growing media with and without supplemental fertilizer during transplant production in three diverse locations. A 5N–0.88P–3.32K–3Ca (5–2–4) dry fertilizer was tested in all media, and a liquid 3N–0.88P–2.49K (3–2–3) fertilizer was …

Mohs, Robert M. Hoffman, Surinder K. Batra, Michael Bouvet

Journal Articles: Biochemistry & Molecular Biology

BACKGROUND/OBJECTIVES: Pancreatic cancer is the fourth leading cause of deaths related to cancer. It is a highly aggressive malignancy and often metastasizes quickly to other parts of the body and organs. The most effective cure is surgical resection, which also is limited by tumor identification and clear tumor margin visualization. Previously, we used MUC4 antibodies labeled with IRDye800CW (anti-MUC4-IR800) to target primary human pancreatic cancer in orthotopic cell line mouse models.

METHODS: In the present study, we established a pancreatic cancer liver metastasis mouse model by implanting a tumor fragment in the liver and a peritoneal carcinomatosis mouse model by …

Ways Of Living And Knowing, Reem El Hassan Mohamed

Theses and Dissertations

After decades of sedentarization, the Muzeina tribe in South Sinai now has new generations born into sedentary lifestyles, never experiencing nomadism like their ancestors once did. This shift has impacted their knowledge system, traditionally shaped by interactions and kinship with nature. Exposure to social media is influencing younger generations' ways of living, raising the older generations’ concerns about their Bedouin identity. Despite being one of the largest tribes in South Sinai, the Muzeina are rarely represented in literature.

This ethnography explores the impact of sedentarization and contextual developments on the Muzeina's knowledge system, inherited from their ancestors. Muzeina’s relationship, and …

Finding Meaning In Loss: The Role Of Attachment Styles, Coping Strategies, And Resilience, Salma Seyam

Theses and Dissertations

Grief is a deeply personal yet universal experience impacted by personal, social, and cultural factors. The present study examines how attachment styles, coping mechanisms, and resilience impact both grief intensity and the ability to find meaning after a loss, within an Egyptian sample. While previous studies have explored the experience of grief, few have looked at these factors within a Middle Eastern cultural context. A total of 140 bereaved Egyptians who experienced the loss of a loved one within the past three years completed standardized measures assessing grief intensity (Prolonged Grief Disorder-Revised; PG-13-R), coping strategies (Brief COPE), meaning-making (Grief and …

Exploring The Role Of Religious Media In Shaping Public Perceptions Towards Climate Change In Egypt, Hebatullah Ashour Abdel Fatah Ibrahim Ashour

Theses and Dissertations

Climate change poses significant threats globally, with particular vulnerability noted in developing nations like Egypt. While effective communication is crucial for societal engagement, the role of influential actors like religious media within specific cultural contexts remains under-explored. This thesis investigates the role and communication practices of religious media (Islamic and Coptic Christian) concerning climate change in Egypt, a country where religious institutions command significant public trust and influence. Existing literature highlights gaps in understanding how these specific media outlets navigate and frame climate change discourse.

Science Communication Through Cool Critters: An Informal Learning Experience For Youth, Jamila L. Bajelan, Mary J. Harner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There are numerous ways to communicate science and assess the effectiveness of that communication. One approach focuses on increasing awareness, enjoyment, interest, opinion, and/or understanding of science. For this study, we created an informal learning experience for youth to communicate the science of animals in Nebraska. We developed Cool Critters, a weeklong summer camp for elementary school-aged students, to increase participants' enjoyment, interest, and opinion of Nebraska animals. In 2023, Cool Critters was led in three educational settings in central Nebraska and reached sixty-six participants. Surveys were used to determine the camp's success in effective science communication and whether …

The Communal Lyric: Poetry In Devotional And Oppressed Communities, Michael N. Yacoub

Theses and Dissertations

This thesis investigates the interaction between lyric and community; it asks what a communal lyric is, how it functions, and to what ends. In Chapter One, I compare Jonathan Culler’s performative model of lyric with the theory of Takhyīl as expounded by Arab philosopher-critics al-Farabi, Ibn Sina, and al-Qartajanni to argue that a communal lyric is a form of audience-oriented public discourse distinguished by formal features that prompt the poem’s (re-)iteration and establish an interpersonal relationship with the audience in order to influence them and make shareable value claims about the world. In Chapters Two and Three I provide close-reading …

“Redefining The Fortress” Migrant Experiences, Adaptation And Connection Within Serbian Borderlands, Nicholas J. Leone

Theses and Dissertations

Abstract This thesis seeks to examine migrant experiences due to Serbia's geopolitical significance along the so-called Balkan route, and how this is specifically exemplified in the northern autonomous region of Vojvodina. Serbia’s position outside the external border of the European Union has caused it to be a strategic transit point for migrants en route to desired destinations, typically within Western and Northern Europe. However, the European Union’s externalization policies in partnership with Serbian authorities have played an extensive role in migration mobility patterns and humanitarian conditions for migrants traversing within the Serbian borderlands, specifically along the border with Hungary. The …

Theses and Dissertations

This research explores the protection of Syrian unaccompanied and separated children (UASC) in Egypt who have fled the Syrian conflict and reflects on the role of formal protection providers and informal networks of solidarity. In hopes of pushing back against the over- essentialization of UASC as vulnerable children, this research unravels the lived experiences of seven aged-out Syrian UASCs who have been living in Egypt for a few years, which reveals their authentic and original crafting of spheres of protection. This thesis aims to contribute to a more extensive and more accurate understanding of the lives and needs of Syrian …

The Cellular Mechanisms Of Alzheimer's Disease Protection By The Pilra G78r Variant, Wenhan Cheng

Theses and Dissertations

Microglial dysfunction is increasingly linked to Alzheimer’s Disease (AD). Immune receptors like TREM2 and CD33 play opposing roles in microglial activity. TREM2 activation triggers immunoreceptor tyrosine-based activation motif (ITAM) signaling to promote microglial activities, including amyloid-β clearance, but variants in TREM2 such as R47H that impair its function increase AD risk. In contrast, CD33 is an inhibitory receptor that contains an immunoreceptor tyrosine-based inhibitory motif (ITIM) which transmits signals that suppress microglial function. An AD-protective variant in CD33 alters CD33 activity, potentially enhancing TREM2 function. PILRA is another inhibitory immune receptor expressed by microglia that contains an ITIM. A naturally …

Strategic Narratives To Counter Global Threats, Jerry E. Landrum, Chase Metcalf, Michael M. Posey

The US Army War College Quarterly: Parameters

This article argues that the current National Security Strategy lacks the necessary coherence and fidelity to mobilize collective action against the emerging Russia-China axis. It merges multiple theoretical concepts to assert that the “rules-based order” theme is insufficient for mobilizing public support. Using textual analysis of the strategy compared with publicly available polling to determine levels of popular resonance, the authors find that the “rules-based order emphasis” does not resonate. This study’s conclusions will assist practitioners as they develop an updated National Security Strategy in the new presidential administration.

The Enduring Lessons Of Vietnam: Implications For Us Strategy And Policy, Martin G. Clemis

The US Army War College Quarterly: Parameters

This article argues that the Vietnam War is a useful case study for assessing an enduring flaw in America’s approach to war. The United States suffered defeat in Vietnam because it privileged military strength and the pursuit of victory on the battlefield over other elements of national power. As in Vietnam, the wars America will likely face in the future will blend conventional and unconventional methods and use a carefully calibrated mixture of military and non-military means. The United States must situate its demonstrated strengths in conventional war fighting within a holistic framework or face similar strategic outcomes.

What The Russia-Ukraine Conflict Tells Us About Educational Resilience, Jason Jabbari

The US Army War College Quarterly: Parameters

Education, which can operate as a source of vulnerability or resiliency across multiple domains before, during, and after armed conflicts, is often only examined within a single domain, limiting the use and effectiveness of civil-affairs operations. This article outlines a novel conceptual framework of the primary mechanisms across seven unique domains by which education can serve as a key area of resiliency or vulnerability. A case study of Russia’s invasion of Ukraine illustrates how vulnerabilities can manifest in the seven domains and what military planners can do to build resiliency. The article concludes with a discussion of the costs, benefits, …

Self-Assessment In Educational Makerspaces: Exploring Self-Regulated Learning As A Formative Assessment Tool, Sarah Margalus

Theses and Dissertations from DePaul University

This study explores the role of self-assessment in makerspaces, examining how students engage in metacognitive reflection and self-regulation within these creative environments. Although self-assessment is the most popular assessment strategy in educational makerspaces, little research has been done on how to best support teachers and students in their attempts at self-assessment. Self-regulated learning was chosen as a theoretical framework since it is well-researched in educational psychology, leads to positive learning outcomes, and is one example of self-assessment. This study employed a qualitative approach, using concept content analysis to evaluate the presence of self-regulated learning phases in blogs written as part …

Crispr-Dcas9 Genomic Engineering For Boosting The Therapeutic Potential Of Extracellular Vesicles, Iker Martinez Zalbidea

Theses

Degenerative disc disease is a major contributor to low back pain, characterized by inflammation of the intervertebral disc (IVD), degradation of the extracellular matrix, loss of hydration, and cell death. Current therapies fail to address these underlying mechanisms, underscoring the need for regenerative strategies. Mesenchymal stem cells (MSCs) exhibit immunomodulatory and regenerative potential, but their efficacy is hampered by the harsh microenvironment of the degenerated IVD. Acellular MSC-derived extracellular vesicles (EVs) have shown therapeutic potential and offer a promising alternative for IVD regeneration. Here, we explore CRISPR-dCas9 mediated activation of TSG6 and STEAP3 to boost the therapeutic potency and biogenesis …

Examining The Impact Of Single-Case Design Graph Characteristics On Decision-Making For School-Based Professionals Within An Mtss Context, Jessica L. Andrews

USF Tampa Graduate Theses and Dissertations

Research investigating the display of single-case design (SCD) data has demonstrated that graphing characteristics can influence visual analysis and rater interpretations regarding the effect of an intervention. Data-based decision making within school settings, particularly within the framework of Multi-Tiered Systems of Support (MTSS), commonly includes the use of SCD’s to support this process. Despite the push for adherence to a standard assembly for linear graphs, there is no requirement as to how these graphs should be constructed. MTSS team members are often required to make decisions about whether an intervention should be continued (or not), and thus it is important …
