Luxury Of Entertainment: Positioning Live Events As Third Places, Kelsie T. Martin
Luxury Of Entertainment: Positioning Live Events As Third Places, Kelsie T. Martin
Honors College Theses
This study examines the shift of live entertainment into a luxury commodity and its implications for social accessibility and cultural participation. Rising ticket prices, dynamic pricing models, and industry consolidation restrict access to concerts and festivals to higher-income audiences, as seen through companies such as Live Nation. This increasing trend in the entertainment industry contradicts the original purpose of live entertainment and music events as a shared cultural experience.
By incorporating Ray Oldenburg’s theory of “third places,” this research explores how live events can function as inclusive social spaces that foster community, belonging, and social connection. Using an applied case …

Developing A Method For Controlled Substance Analysis Using Lcms For Future Dart Ms Applications, Carol N. Muñiz Silva
Honors Theses
Liquid chromatography–mass spectrometry (LC-MS) is an analytical technique used to separate and identify compounds and is widely applied in forensic toxicology and controlled substance analysis due to its strong capabilities in detection, identification, and quantification. In this experiment, a method for analyzing acetaminophen was developed using mobile phases of 0.1% formic acid in water and 0.1% formic acid in methanol. Method development focused on adjusting elution time, mobile-phase gradient, and injection volume. The optimized method produced reliable analysis of acetaminophen across 100–7500 ng/mL. Quantitative and qualitative data were collected through chromatograms and mass spectra of the prepared solutions. Although a …
The Paradox Of Ambition:Global South Leadership And Brazil's Stalled Rise To Global Power, Valentinna De Melo Ferrarini
The Paradox Of Ambition:Global South Leadership And Brazil's Stalled Rise To Global Power, Valentinna De Melo Ferrarini
Honors Theses
Brazil possesses the material resources, territorial size, and regional influence typically associated with global powers, yet remains excluded from recognition as one. This thesis examines how Brazil's leadership of the Global South has shaped and at times constrained its ambition to become more than a middle power. Using Wang and Chen's comprehensive national power measurements, it tracks Brazil's dramatic trajectory: a 72% increase in national power between 2005 and 2010, followed by a 43% decline by 2020. To explain this reversal, the thesis develops a delta framework identifying six key impediments: regional leadership failure, recognition deficit, military limitations, political instability, …

Re-Imagining The Rimac River: Designing With Mythology, Ecology, And Community, Rodrigo Carbajal
Re-Imagining The Rimac River: Designing With Mythology, Ecology, And Community, Rodrigo Carbajal
Bachelor of Architecture Theses - 5th Year
The Rímac River sustains Lima, yet the city has treated it more like an edge condition than a living system. Its water moves through the metropolis as a source of life, but its presence is buried behind concrete walls, traffic corridors, pollution, and fragmented access. Over time, the river has been reduced to a controlled channel, stripped of the cultural and spatial relationships that once connected it to everyday life. This thesis begins with that contradiction: the Rímac remains vital to Lima’s survival, but has been pushed out of the city’s public imagination. This project argues that the river’s current …
Architecture Of Sobriety: Redesigning Rehabilitation Centers Beyond The Institutional Framework, Coraima Perez-Portillo
Architecture Of Sobriety: Redesigning Rehabilitation Centers Beyond The Institutional Framework, Coraima Perez-Portillo
Bachelor of Architecture Theses - 5th Year
What if alcohol relapse is not only a weakness of will, but a failure of the environment? Addiction recovery is often understood as a clinical process, yet sustained sobriety depends equally on the reorganization of daily habits. Research on alcohol use disorders demonstrates that addictive behaviors are reinforced through spatial triggers and embodied routine. Post-detox recovery is particularly fragile: the body is sober, but the triggers that sustained addiction remain. The question is not only how to treat addiction, but how to design the spaces in which people learn to live without it.
This thesis investigates how architecture can combat …
Addressing The Abandoned Typology Of Mills, Terra M. Castresana
Addressing The Abandoned Typology Of Mills, Terra M. Castresana
Bachelor of Architecture Theses - 5th Year
As anthropologists have shown, rivers are foundational to the creation of human settlement, and many cities design their urban fabric to interact with their respective rivers. Despite the scale of the Chattahoochee River, however, a typical visitor of Atlanta might not see the river as it is covered with highways and other infrastructures. Since the inception of colonial Atlanta as a railroad town in the nineteenth century, the urban design deviated from having the rivers be central to the city’s evolution as scholarship shows. Despite this structural arrangement, there was still an existing relationship with its rivers when waterways, most …
Synthergy: Social Deduction And Deception In Llm-Powered Agents, Lauren Campbell, Andrew Forney
Synthergy: Social Deduction And Deception In Llm-Powered Agents, Lauren Campbell, Andrew Forney
Honors Thesis
Synthergy is an online social deduction game designed to enable comparative analysis of how large language model-powered agents engage in social deduction and deception under conditions of asymmetric information. Inspired by social deduction games such as Town of Salem, Throne of Lies, and Mafia, the game consists of two factions, Harmony and Discord, to which agents are secretly assigned. Agents must infer others’ affiliations through dialogue, in-game abilities, and voting behavior. To evaluate agent behavior, we conducted 100 simulated games across six agent types: a random baseline agent (RandomSynth), an LLM-based agent (Synth), a chain-of-thought agent (CoT Synth), a Bayesian …
Adaptive Two-Derivative Runge–Kutta–Nyström Method With Trigonometric Fitting Approach, Nur Nabila Huda, Khai Chien Lee, Nurul Huda Abdul Aziz
Adaptive Two-Derivative Runge–Kutta–Nyström Method With Trigonometric Fitting Approach, Nur Nabila Huda, Khai Chien Lee, Nurul Huda Abdul Aziz
Turkish Journal of Mathematics
A fifth-order trigonometrically-fitted explicit two-derivative Runge–Kutta–Nyström method with an adaptive step size strategy, denoted as ATFRKN5, is proposed for efficiently solving second-order ordinary differential equations of the form u″(x) = f(x, u(x)) that exhibit oscillatory behavior. The order conditions of the method are derived using Taylor series expansion, enabling the construction of two-derivative Runge–Kutta–Nyström schemes up to orders four and five. Trigonometric fitting is applied by incorporating the basis functions eiλx and e−iλx, λ ∈ ℝ, allowing the method to adapt naturally to problems with dominant frequencies. …
On Sequences Arising From The Action Of Modular Group, Tuncay Köroğlu, Bahadir Özgür Güler
On Sequences Arising From The Action Of Modular Group, Tuncay Köroğlu, Bahadir Özgür Güler
Turkish Journal of Mathematics
This paper examines the sequences produced by the natural action of specific elements of the modular group on extended rational numbers. The polynomial sequences Pr(c) and Qr(c) are derived from the orbit of the point at infinity under a specific modular transformation. These sequences satisfy linear recurrence relations, which are analyzed using generating functions. The polynomials encode k-Fibonacci numbers, and studying their behavior modulo a fixed integer m reveals notable arithmetic and combinatorial properties. We also explore the connection between these modular actions and Farey graphs, illustrating the hyperbolic transformations as nested geodesic paths in the upper half-plane.

A Module Theoretic Approach To (B,C)-Invertibility, Tuğba Pakel, Burcu Üngör, Handan Köse, Sai̇t Halicioğlu, Abdullah Harmanci
Turkish Journal of Mathematics
In this paper, we introduce and investigate the concept of an (r, f)-inverse in the context of modules, drawing inspiration from the (b, c)-inverse, which is the analogous notion in ring theory. We demonstrate the uniqueness of (r, f)-inverses in modules whenever they exist. We provide some necessary and sufficient conditions for the existence of (r, f)-inverses in modules.

Proportion Of Nilpotent Subgroups In Finite Groups And Their Properties, João Victor Monteiros De Andrade, Leonardo Santos Da Cruz
Proportion Of Nilpotent Subgroups In Finite Groups And Their Properties, João Victor Monteiros De Andrade, Leonardo Santos Da Cruz
Turkish Journal of Mathematics
This work introduces and investigates the function J(G) = Nil(G) / L(G) , where Nil(G) denotes the number of nilpotent subgroups and L(G) the total number of subgroups of a finite group G. The function J(G), defined on the interval (0,1], represents the proportion of nilpotent subgroups relative to the total number of subgroups, including trivial ones. It serves as a tool for analyzing structural patterns in finite groups, particularly in nonnilpotent families such as supersolvable and dihedral groups. Analytical results reveal the distribution of J(G) values across products of dihedral groups, emphasizing its density over (0,1]. Additionally, a probabilistic …

Optimal Control Of An Inverse Two-Point Boundary Value Problem For A Pseudoparabolic Equation With Samarskii–Ionkin-Type Boundary Conditions, Khanlar R. Mamedov, Tursun K. Yuldashev, Zholdoshbek Zh. Shermamatov
Turkish Journal of Mathematics
This paper investigates an inverse optimal control problem for a pseudoparabolic equation governed by nonlinear control function in a two-point boundary condition. The differential equation is considered under Samarskii Ionkin-type boundary value conditions with respect to the spatial variable x. Necessary optimality conditions are derived, and the associated nonlinear functional equations are analyzed. Using the contraction mapping principle, the existence and uniqueness of the control function are established. Subsequently, the redefinition function and the state function are determined. The convergence of their respective Fourier series representations is rigorously proven.

Turkish Journal of Mathematics
This paper presents comparative results on the two-parameter weighted mixed estimator, which is a distinct class of estimator defined to address the problem of multicollinearity. The two-parameter weighted mixed estimator is a general estimator that includes the weighted mixed estimator, the weighted mixed Liu estimator, and the weighted mixed ridge estimator. Detailed comparisons among the mentioned estimators are carried out based on the matrix mean square error. Theoretical findings are supported by two numerical examples in addition to a Monte Carlo simulation study.
