From Uncertainty To Strategic Failure: U.S. Military Interventions And The Complexity Of Nation-Building In Afghanistan, Goddy Uwa Osimen, Oluwamurewa Newo

Journal of Strategic Security

The American occupation of Afghanistan from 2001-2021 is widely regarded as a strategic failure, particularly after the Taliban took over the government in 2021. This work seeks to observe the strategic flaws of the 20-year occupation from the perspective of nation-building within the state. Using the theoretical lens of strategic culture and borrowing from Huntington’s discourse on the clash of civilizations, this article notes that nation-building failure in Afghanistan can be attributed to the ideological differences between the West and the Middle East. Using a descriptive qualitative approach and secondary sources such as books and peer-reviewed articles, the study employs …

Reliance On Local Contractors And Messy Withdrawals: Lessons From Afghanistan, Guido Rossi

Journal of Strategic Security

The U.S. withdrawal from Afghanistan in 2021 highlighted both American unpreparedness for evacuating large numbers of foreign civilians as well over-reliance on local contractors that made the evacuation a task of much greater proportions. As a result, the United States were forced to renege on its promises of protection to many Afghan collaborators who were left behind exposed to Taliban retribution. However, the U.S. could not only have handled the evacuation and resettlement operation of Afghan civilians much more effectively through better contingency planning, interagency communication, and coordination, but it could also have prevented massive reliance on local contractors through …

Learning From Afghanistan: The Futility Of Occupation In Nation-Building, Jithin Raveendran

Journal of Strategic Security

This article explores the challenges and failures of nation-building under occupation Amidst an active warfare, using Afghanistan as a critical case study. Over two decades, the US-led intervention sought to establish stability and democracy but ultimately faltered due to misaligned strategies and systemic flaws. Efforts to impose Western governance structures clashed with Afghanistan’s deeply rooted tribal and cultural norms, fueling resistance and eroding legitimacy. The article identifies key shortcomings, including the neglect of local agency, cultural insensitivity, over-reliance on military solutions, and the perpetuation of dependency and corruption. It argues that nation-building by occupying forces is inherently flawed without prioritizing …

Our Knowledge Of The Taliban As Guide For Us Policy, Marvin G. Weinbaum

Journal of Strategic Security

Many explanations have been offered for why after two decades of insurgency the US military mission in Afghanistan failed. Some of our judgments about what went wrong can be useful in helping us shape future US policy toward a Taliban-ruled Afghanistan. Even more valuable, we have the benefit of several years of observing the Taliban exercising the responsibilities of governing to guide us in engaging the regime and furthering our security and strategic objectives with Afghanistan and its region. This article identifies seven broad conclusions about the Taliban that should be instructive: Among these are the Taliban’s resistance to transactional …

Beyond The Gray Ghost: John S. Mosby And The Power Of Legend, Kevin R. Youngberg

USF Tampa Graduate Theses and Dissertations

Civil War generals are among the most celebrated figures of their time. In the post-Civil war era, many of these officers retreated to farms, and businesses and disappeared into obscurity. This was not the case with Colonel John Singleton Mosby, who quickly transformed into a figure whose legacy from the Civil war gave him a unique place in the American imagination as the legendary Gray Ghost of the Shenandoah Valley of Virginia. He lived until 1916, a remarkable fifty years filling those decades with a host of accomplishments in public service both at home and abroad. His legacy is complex, …

An Fgfr-P53 Developmental Signaling Axis Drives Salivary Cancer Progression, Julia M. R. Billington

USF Tampa Graduate Theses and Dissertations

Mucoepidermoid carcinoma (MEC) is the most frequently occurring salivary gland malignancy.Here, we investigated transcriptomic profiles of human fetal and adult salivary glands and MEC tumors to assess programs involved in MEC progression. Molecular and genetic analyses revealed that MEC tumors and fetal salivary glands share proliferative and developmental gene expression profiles that implicate an FGFR-p53 signaling axis in salivary MEC progression. Based on these findings, we developed a genetically engineered mouse model of advanced MEC via targeted expression of the CRTC1-MAML2 oncogene in salivary ductal cells. Specifically, CRTC1- MAML2 expression combined with p53 dysregulation in salivary ducts rewires FGF signaling …

An Exploratory Analysis Of Automated Deception Detection For Mental Health Applications, Sayde Leya King

USF Tampa Graduate Theses and Dissertations

Deception in mental health settings can undermine therapeutic relationships, compromise treatment efficacy, and impact patient outcomes. Yet, research shows that mental health clinicians often perform no better than chance at detecting deceptive behavior in therapy. Automated deception detection, leveraging artificial intelligence (AI) and multimodal behavioral cues—such as eye gaze, body gestures, and facial expressions—offers a promising alternative. However, most existing research focuses on high-stakes legal contexts, limiting its applicability to mental health settings.

This dissertation addresses this gap by pursuing three key research objectives using a mixed-methods approach. First, we investigate mental health clinicians’ perspectives on AI-assisted deception detection through …

Efficient Methods And Algorithms For Analyzing Stochastic Systems, Mohammad Ahmadi

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the challenges of stochastic analysis of safety-critical systems with biological components, where unexpected behavior can lead to catastrophic events. Two fundamental challenges hinder the analysis of such systems: their typically large or infinite state spaces, and the extreme rarity of error states of interest. While Monte Carlo simulation can analyze biochemical systems without storing the state space, accurately estimating rare event probabilities becomes computationally prohibitive. Conversely, probabilistic model checking excels at analyzing extremely low probability events but becomes impractical for systems with large or infinite state spaces due to memory constraints.This work proposes two main contributions to …

Physical Activity And Functional Mobility In Adults With Hearing Loss: A Series Of Embedded Studies Within A 6-Month Clinical Trial With Hearing Aids, Sarah L. Bochat

USF Tampa Graduate Theses and Dissertations

Adults with hearing loss engage in low levels of physical activity and demonstrate poor performance on measures of functional mobility. The impact of hearing rehabilitation on these outcomes is not fully understood. Previous investigations were largely quantitative and focused on older adults ≥ 65 years of age who may respond differently to hearing intervention than relatively younger adults. They also tended to focus on exercise rather than global engagement in physical activities and did not report hours of hearing aid use, an important indicator of intervention success. One purpose of this dissertation was to determine the feasibility of collecting accelerometry-assessed …

The Role Of Langmuir Circulation In Coastal Flows Driven By Wind, Waves And Tides, Thathsarani Dilini Herath Herath Mudiyanselage

USF Tampa Graduate Theses and Dissertations

Langmuir Circulation (LC) is a wind and wave-driven process and is a key driver of vertical mixing and transport in the ocean. In coastal shelf regions, LC can span the entire water column, linking surface and bottom boundary layers and amplifying turbulent mixing. However, the influence of LC on vertical mixing and cross-shelf transport in shallow, tidally forced coastal waters remains poorly understood. This dissertation addresses this knowledge gap by developing a novel modeling framework based on the Reynolds-Averaged Navier–Stokes (RANS) equations, offering a computationally efficient alternative to more resource-intensive Large Eddy Simulations (LES).

The proposed RANS-based approach is first …

Democracy, Expertise, And The Disinformation Problem, Richard Randall Frohock Iv

USF Tampa Graduate Theses and Dissertations

Experts are an essential part of our social epistemology. They grant us access to knowledge that would otherwise be inaccessible. Because of this, experts are also typically seen as invaluable political contributors. Without expert contributions, public policy risks being ill-informed and therefore incapable of addressing society’s needs. Recently, however, the extent to which expertise should inform public policy has come into question. Fueled largely by disinformation, there is a growing movement against traditional experts. Those within this movement argue that experts have overstepped their bounds and are working against the societies they are meant to be helping. Fearing that that …

Does Practice Make Perfect? Examining The Impact Of Text-Based Reminders On Adherence In The Helping Our Toddlers, Developing Our Children’S Skills Program, Lauren Patrusky

USF Tampa Graduate Theses and Dissertations

Disruptive behavior disorders (DBDs) are prevalent in approximately 17% of children ages birth to 5 years (CDC, 2023). DBDs can significantly impact a child’s learning, social-emotional wellbeing, and ability to develop and maintain healthy relationship (CDC, 2023). Behavioral parent training (BPT) has been proven effective in reducing disruptive behavior and improving parent-child relationships. However, many families do not fully engage in treatment, leading to poor outcomes for both the child and the family. Chacko (2016) describes BPT engagement as enrolling in treatment, attending weekly sessions, participating in group discussions or role plays in sessions, practicing skills between sessions, and completing …

Which Adolescents Benefit Most From Positive Psychology Interventions: Examining The Common Factors Of Therapeutic Change, Nicolette Bauermeister

USF Tampa Graduate Theses and Dissertations

The literature has found positive psychology interventions to be effective at improving the subjective well-being of youth (Tejada-Gallardo et al., 2020). Further research is needed to identify variables such as common factors of change that could be contributing to whether youth report improved outcomes after participating in a positive psychology intervention. This study examined common factors of therapeutic change as predictors for outcomes such as positive affect, negative affect, and life satisfaction, which are components of subjective well-being. This dissertation aimed to fill the gap in the literature regarding common factors of change as predictors of outcomes in school-based positive …

The Only Constant Is Change: The Role Of Genetic Diversification In Cancer And Beyond, Malgorzata Tyczynska Weh

USF Tampa Graduate Theses and Dissertations

Genetic diversification, the process by which genetic variation arises in a population, is fundamental to evolution by natural selection. Mutation, a central diversification process, fuels adaptation across species, including in cancer. Yet most new mutations are neutral or deleterious on cell fitness, raising the question of how mutation-driven adaptation persists. To explore this paradox, I developed a spatial agent-based model (ABM) in which population fitness emerges from individual cells acquiring mutations at varied rates and with diverse fitness effects. I evaluated model behavior across adaptive states, mutation rates, and distributions of fitness effects. The results show that high mutation rates …

Moreover, recent studies have demonstrated the effectiveness of BST for enhancing sports performance when training neurotypical children and adults. However, there is limited research on the effectiveness of BST for enhancing sports performance, and specifically dance performance, among individuals with autism spectrum disorder (ASD) and/or intellectual disabilities (ID). Dance is a recreational activity that can serve as a form of physical activity for children and adults. Salsa is a Latin style …

Utilization Of Bixin-Loaded Polycaprolactone Nanoparticles To Ameliorate E-Cigarette-Induced Damage To Human Bronchial Epithelial Cells, Sophia R. Claymore

USF Tampa Graduate Theses and Dissertations

Electronic cigarettes (e-cigs) have increased in popularity and usage over the last few decades. E-cigs are generally composed of a liquid containing nicotine flavoring chemicals, a battery, a vaporization chamber, and a coil that heats the liquid upon inhalation of the mouthpiece. E-cigs were initially introduced as a healthy alternative to cigarette smoking. However, recent research has demonstrated that e-cigs elicit comparable cytotoxic and dangerous effects to conventional cigarettes. Bixin has been introduced in recent research as a candidate for therapeutic applications due to its innate anticancer, antioxidative, and anti-inflammatory characteristics. Nanoparticles (NPs) have emerged over the past few decades …

An Application Of A Positive Psychology Intervention To Promote The Well-Being Of Children With Cancer, Jenna Barnes

USF Tampa Graduate Theses and Dissertations

The psychological impact of pediatric cancer and cancer treatment is not well understood. Although there is evidence to suggest that pediatric cancer may negatively impact youth’s mental health and psychological functioning, other research suggests that the mental health of children with cancer is similar to that of healthy peers. Traditional psychological interventions have been used to reduce symptoms of psychopathology among children with cancer. However, less is known about the subjective well-being of children with cancer and evidence-based, positive psychology interventions to promote the subjective well-being of this population. Thus, this study sought to address this gap in the literature …

Untangling The Threads Of Hope: A Qualitative Media Analysis Of Discourse Relating To Futures For Sickle Cell Disease, Amanda R. Malerba

USF Tampa Graduate Theses and Dissertations

Sickle cell disease (SCD) is the most common inherited blood disorder worldwide, with a disproportionate burden on people of African ancestry. Life with this illness is characterized by chronic physical pain, overlapping health conditions, and often early death. In the United States, the physical symptoms of the disease are frequently compounded by experiences of racial inequality and oppression embedded in the medical system that contribute to detrimental outcomes. Because of the complex biocultural web of factors contributing to the suffering of people with SCD, much of the anthropological scholarship surrounding this illness prioritizes deconstructing systems of power, oppression, and inequality. …
