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 …

Taliban 1.0 And 2.0 In Afghanistan: Same Policies, Persistent Vision, Sharif Hozoori

Journal of Strategic Security

The Taliban emerged as a movement in 1994, toppled the government of the Mujahideen, and ruled Afghanistan from 1996 to 2001. They finally recaptured power in 2021 after the US withdrawal from the region. This paper refers to the first Taliban rule as Taliban 1.0 and their second as Taliban 2.0. Taliban 1.0 imposed draconian laws and regulations on women and minorities while harboring regional and international terrorist organizations. Later, the Taliban 2.0 followed its predecessor in policies regarding women, minorities, and sheltering terrorist organizations. Considering this background, this paper addresses whether Taliban 1.0 and 2.0 maintain the same policies …

Afghanistan: Taliban’S Second Chance And Red Strategy, Oleg Golishnikov

Journal of Strategic Security

An objective evaluation of Afghanistan’s political and socioeconomic situation since the Taliban’s takeover in August 2021 is crucial for understanding and addressing security issues at the national, regional, and global levels. Unlike most studies, this article provides new insights, offering a balanced assessment of the situation in Afghanistan and developing recommendations on dealing with the Taliban regime. By employing qualitative methods and a rational theory framework, this article argues that Afghanistan under Taliban rule is experiencing a mix of positive and negative trends. Major positive trends include the relative peace in Afghanistan, the Taliban’s real power and control over the …

Phosphorus: From The Origins Of Life To The Origin Of An Industry, Joshua Abbatiello

USF Tampa Graduate Theses and Dissertations

The element phosphorus is a key biogenic element that is often the limiting reagent for life. Phosphorus is quickly bound by metal divalent cations making it virtually insoluble and inert in water (forming the phosphate mineral apatite). Due to this, it becomes imperative to understand alternative pathways to increase biogenically available phosphorus in environments. To that end, this dissertation involved examining olivine as an alternative source of phosphorus to apatite, analyzing a novel grain of iron silicide found via lightning reduction in a fulgurite, and finally sought to understand the impact of phosphate mining through phosphogypsum stacks. Olivine is a …

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 …

The Political Philosophy Of Habitude: Conservatism Analytically Explained, Kyle S. Hodge

USF Tampa Graduate Theses and Dissertations

Conservatism is both undertheorized and poorly understood in philosophical political theory; all extant theories have proven deficient. They either conflate what is contingently associated with conservatism with its essence, draw mistaken generalizations from apparently conservative behavior, or else are explanatorily incomplete.

To avoid these deficiencies, I develop a rigorous, theory-neutral groundwork for evaluating theories of conservatism. This groundwork utilizes both traditional methods of analytic philosophy and, for the first time in the field, historiometry. Philosophical analysis determines the formal requirements of a successful explanation while empirical, historiometric data determines the most salient conservative exemplars whom any such theory must explain. …

The Synthesis Of A Photo-Affinity Probe Library For The Fatty Acid Amide Proteome And The Endocannabinoid System Within, Robert E. Feeney Iii

USF Tampa Graduate Theses and Dissertations

Fatty acid amides are a large family of endogenous metabolites with significant biological activity, including that of the endocannabinoid system. Currently little is known about how this system of tightly regulated compounds works within humans. This work lays the foundation to explore the structure-activity relationship driving the selectivity of ligand-protein interactions involved with fatty acid amides. A library of activity-based proteomic profiling probes for fatty acid amides has been synthesized to this end. Additionally, progress towards phytocannabinoid probes has been made as well.

Corrosion Mitigation And Monitoring Of Bridge Tendons And Failure Forecasting Of Wastewater Force Mains, Stanley Chike Agbakansi

USF Tampa Graduate Theses and Dissertations

Corrosion remains a significant threat to civil infrastructure, resulting in costly repairsand potential structural failures. This dissertation addresses three critical aspects of corrosion: mitigation and monitoring of post-tensioned bridge tendons, and failure forecasting of wastewater force mains due to internal corrosion.

First, the research investigates the effectiveness of corrosion inhibitors (CIs) applied via pressure injection (impregnation) in post-tensioned tendons. The protective mechanisms and long-term performance of various inhibitors were evaluated to identify the most effective formulations. Among the tested inhibitors, MCI-2020 — a water-based, migratory, mixed-type corrosion inhibitor — demonstrated the most promising results, showing excellent corrosion protection while preserving …

The "N" Framework: A Teacher Knowledge Framework For Numeracy Across The Curriculum, Kathy O'Sullivan, Niamh O'Meara, Merrilyn Goos, Paul Conway

Numeracy

Governments and policymakers around the world are encouraging teachers to teach numeracy across the curriculum. This paper proposes a theoretical framework for the knowledge required to teach numeracy across multiple disciplines. The concept of teacher knowledge is complex and consists of many different facets of knowledge. This paper proposes a framework that integrates theories from existing models of general and subject specific teacher knowledge, along with a model of numeracy. The authors developed the "N" framework, an integrated framework of numeracy knowledge, subject specific knowledge, and pedagogical content knowledge. Each element is essential for teaching numeracy across the curriculum in …

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 …

Digital Resistance And The Political Economy Of Authoritarian Decline And Economic Liberalization In Ethiopia, Anaol Dalle

USF Tampa Graduate Theses and Dissertations

This dissertation aims to examine the impact increased consumption of digital technologies, like social media and the internet, has on the stability and autonomy of low-capacity authoritarian countries. By using Ethiopia (2015-2021) as a case study, the dissertation argues that the sudden adoption and proliferation of digital platforms serves as an exogenous shock that pushes the state into a critical juncture that unravels institutional equilibria and transforms domestic incentive structures and institutions. This creates a power vacuum, which triggers a period of intense, and often violent, competition between elite groups, significantly destabilizing the state. In the absence of a cohesive …

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 approach used involves gamifying matrix training, an empirically supported method for teaching word combinations and promoting the generalization of language skills. Across three studies, the development of an instructional game is described and evaluated with two populations, typically developing children and children who are minimally verbal. First, it introduces a gamified application of matrix training that provides training in an interactive digital environment. Second, a proof-of-concept was obtained via a multiple baseline across participants with typically …

Changes In Immune-Regulated Gene Methylation Over Time In Women Who Do And Do Not Develop Breast Cancer, Kyle Laney

USF Tampa Graduate Theses and Dissertations

Breast cancer survivors face elevated risks of chronic inflammatory conditions and immunedysfunction compared to the general population. These elevated health risks in survivors are well-documented but mechanistically poorly understood. This study aimed to characterize longitudinal changes in DNA methylation patterns of immune-regulatory genes in women who developed breast cancer compared to cancer-free controls. We conducted an EWAS using Sister Study cohort data, analyzing longitudinal changes in DNA methylation by comparing the difference in beta values between pre- and post-diagnosis time points in breast cancer cases versus changes over the same period in cancer-free controls. The analysis included 414 participants: 189 …

Isotopic Fingerprints Of The Coastal Margins: Tracing Dissolved Iron Sources From Land To Sea, Hannah R. Hunt

USF Tampa Graduate Theses and Dissertations

Dissolved iron (dFe) is an essential micronutrient for sustaining life in the surface ocean. Nearly four decades of research dedicated to understanding sources, cycling and biogeochemical modifications of Fe sources in the global oceans has generated a significant body of research supporting the idea that the concentration of Fe in the surface ocean exerts significant controls on primary production and carbon uptake in the surface ocean. Creation of the GEOTRACES program greatly increased the spatial and temporal resolution of high-quality trace element and trace element isotope data revealing new insights into the global Fe cycle, especially through the use of …

Applications Of Contracting Self-Similar Groups To Cryptography And Scale Groups, Arsalan Akram Malik

USF Tampa Graduate Theses and Dissertations

Given their peculiar properties, self-similar groups are of great interest both from applications and theoretical standpoints. In this work we study the scope of their applications in post-quantum cryptography and in constructing scale groups via lifting maps.

We propose self-similar contracting groups as a platform for cryptographic schemes based on simultaneous conjugacy search problem (SCSP). This class of groups admits fast polynomial-time algorithms for the word problem and element multiplication that can be used for effective encryption and decryption of messages. It contains extraordinary examples like the Grigorchuk group, which is known to be non-linear, thus making some of existing …

Healthy Bodies, Moral Minds, And Rural Ideals: Contextualizing Interwar British Childhood And Citizenship Through Children's Country Holidays Fund Vacations, Paula J. Pack

USF Tampa Graduate Theses and Dissertations

This dissertation uses the Children’s Country Holidays Fund (CCHF) as a critical lens to examine how philanthropy, childhood, class, public health, and rural nostalgia intersected within the broader context of citizen formation in interwar Britain. Founded in 1884 to provide country holidays for poor London schoolchildren, the CCHF evolved from a philanthropic response to Victorian slum life into an informal arm of welfare governance by the end of the interwar period. Through its country holidays, the Fund became an active participant in shaping ideals of health, morality, and civic responsibility in a period marked by heightened concern over national vitality …

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 …
