Turkish Journal of Chemistry

Novel coumarin–triazole–coumarin dyads were synthesized and characterized, and their α-glycosidase inhibitory activities were evaluated spectrophotometrically. Compound 4e exhibited the most pronounced inhibitory effect, with an IC50 value of 38.98 ± 0.77 μM. The IC50 values for 4d and 4a were 93.55 ± 1.70 μM and 95.04 ± 3.55 μM, respectively. The Lineweaver–Burk plot showed that 4e inhibited α-glycosidase in a mixed type. In addition, the Ki value obtained from the Dixon plot was 19.95 ± 0.15 μM for α-glycosidase.

Optimizing Crime Response Time Using Predictive Analytics Models, Mohammad Hassan Bin Yaqoob

Theses

Timely and efficient emergency response is essential for public safety, particularly in high- risk urban environments. However, existing dispatch systems often rely on reactive decision- making, leading to delays and inefficient resource allocation. This thesis explores how artificial intelligence (AI) and data modeling can enhance police response times through predictive analytics. A systematic review of 17 peer-reviewed studies identified key predictors such as dispatch behavior, crime history, temporal characteristics, and geographic location. Using real-world emergency response and crime data, predictive models were developed and evaluated through algorithms including XGBoost, Linear Support Vector Machine (LSVM), Generalized Linear Model (GLM), and Neural …

Automatic Guitar Transcription Of Polyphonic Music, Ritwik Patil

Master's Theses

Transcribing guitar music automatically is a complex task due to polyphonic overlap, tuning variations, and diverse playing techniques. Current transcription systems focus on identifying note pitches and timing while ignoring performance techniques that describe how the notes are played, treating guitar recordings as generic polyphonic audio and producing MIDI-like outputs that lose important information about articulation and style. To address these challenges, we propose an end-to-end transformer model for automatic guitar transcription. The system uses a T5-based encoder-decoder architecture that processes the Constant-Q Transform (CQT) of stereo audio input. The stereo representation helps separate individual guitar parts within a mix …

The system integrates Copernicus Atmosphere Monitoring Service (CAMS) forecasts, high-resolution meteorological fields, and ground-based air quality observations within a machine learning framework. Three models with varying training periods were systematically evaluated using cross-validation and independent validation with 2024 Aerosol Robotic Network (AERONET) data. The optimal model, trained on 2015–2023 data, achieved …

Absolute Extraction: Utilizing Rural Critical Criminology To Examine Appalachia’S Toxic Dependence On Extractive Industries, Andrew Kennedy

The Mid-Southern Journal of Criminal Justice

Brought forth by common rhetoric, Appalachia is often viewed as the closest space to that of an empyrean domain. Separated from the sleepless city, its allure rests in its created identity of a quiet, green escape from the city, which offers serenity on all fronts. Although Appalachia can fulfill this profile, such an ascension ignores the burning yellow grass below. The purpose of this paper is to examine the history of the destruction of Appalachia through the lens of extractive industries and the region’s designation as a sacrifice zone. Through the application of rural critical criminology, this paper holds that …

The Controlled Substances Act: A Menagerie Of Arbitrary Regulation And Failure Of Purpose, Dylan Andrus

The Mid-Southern Journal of Criminal Justice

The Controlled Substances Act (CSA) is the primary regulatory and criminal legislation surrounding drugs in the United States. Passed in the 1970s, the CSA established the drug classification scheduling system we use today. Despite being over 50 years old today, the CSA has not achieved its goal of eliminating or even significantly reducing drug use and offenses. This paper conducts an analysis of the CSA's legislative intent versus its actual results through reviews of measures such as incarceration rates, inconsistent regulation, and disproportionate racial effects to argue that the Controlled Substances Act has failed in its mission while causing significant …

Bridging The Gap Between Substance Use Treatment Barriers In Rural Areas, Dakota Baker

The Mid-Southern Journal of Criminal Justice

The purpose of this paper is to examine the continued concern about substance abuse/misuse and limited access to treatment in rural areas. Rural areas lack the adequate treatment needed to combat substance use disorder (SUD), mainly due to the lack of sufficient providers trained to identify, treat, and support those dealing with SUD. Additional barriers such as the high cost of treatment, stigma surrounding substance use disorders, geographical barriers, and the criminalization of substance abuse are other barriers that will be discussed in this paper (Griffin & Botvin, 2010; Hargons et al., 2023; Khazaee-Pool et al., 2024; National Center for …

Humane education (HE) encompasses multiple concepts, including animal ethics, ecological environment, and social justice. The problem prompting this study was that individuals who have graduated from a higher education HE program face challenges in successfully integrating HE into their K–12 classrooms. Grounded by Weil's solutionary approach to HE, the purpose of this basic qualitative study was to explore the teaching experiences of individuals who graduated from a higher education HE program and successfully integrated HE into their classrooms. Participants were purposefully sampled from a small population of educators who completed a U.S. degree or certificate program in HE and successfully …

Resting Autonomic Activity, Emotional Reactivity, And Executive Function In Preschool-Age Children Who Stutter, Dana J. Meyerson

Theses - ALL

Purpose: This study investigated whether preschool-aged children who stutter (CWS) differ from children who do not stutter (CWNS) in autonomic physiological reactivity and regulation during a phrase-repetition task paired with affective image-viewing conditions. Additionally, the study investigated whether individual differences in executive function skills, specifically inhibitory control, predicted variability in physiological responses across participants. Methods: Forty-three preschool-aged children (18 CWS, 25 CWNS) completed three laboratory visits that involved collection of electrocardiogram (ECG) recordings at rest and during a phrase-repetition task paired with visual stimuli of either neutral (fixation cross) or negative (IAPS) emotional valence. Inhibitory control was assessed using the …

Intersectionality, Epistemic Injustice, And Silencing: The Operationalization And Reification Of Intersectionality In Academic Research And Institutional Practices, Emery Lockwood

Theses - ALL

Intersectionality is a powerful analytic tool that can be used to better understand the role that oppression plays in society and how it shapes the way people affected by multiple systems of oppression interact with society. Recently, the unit of analysis for intersectionality has started to shift from intersecting systems of oppression to overlapping identities, which has changed intersectionality from being a tool used to analyze systemic oppression to individual’s experiences. This work explores the implications this shift has on academic research and the practice of several disciplines. Using a lens of epistemic injustice through theories of hermeneutical bastardization (Drury, …

Longitudinal Association Between Sleep Disturbance And Disordered Eating In Adolescents: The Mediating Role Of Emotion Dysregulation, Antonia Louise Hamilton

Theses - ALL

Accruing evidence suggests a significant relationship between sleep disturbances and disordered eating. Early adolescence is a period of heightened vulnerability for sleep disturbances and disordered eating. However, the longitudinal relationship between sleep disturbance and disordered eating remains unclear in early adolescent samples. The current study aims to examine if sleep disturbance longitudinally predicts disordered eating in early adolescents three years later, how the odds of having clinically significant disordered eating change per each unit increase in sleep disturbance, and if emotion dysregulation mediates these relationships. It is hypothesized that baseline sleep disturbance will predict greater disordered eating at follow-up, and …

Exploring The Role Of Astrocyte System Xc– In Excitatory/Inhibitory Balance, Samantha Olivia Sutton

Theses - ALL

Astrocytes play a central role in maintaining excitatory/inhibitory (E/I) balance in the central nervous system by supporting intracellular glutathione (GSH) synthesis and regulating extracellular glutamate. System xc– (Sxc–), an obligate cystine/glutamate antiporter encoded by SLC7a11, couples the import of L-cystine with the export of L-glutamate. It is highly expressed throughout the cortex, hippocampus, striatum, and cerebellum, where its activity provides cystine—the rate-limiting substrate for cysteine-dependent GSH production—and contributes to ambient glutamatergic tone. Although global loss of Sxc– alters seizure threshold and redox homeostasis, whether these effects arise specifically from the loss of astrocytic Sxc– has remained unresolved. This thesis examined …

Investigating The "Tend-And-Befriend" Stress Response As A Risk Factor For Sexual Victimization Among College Women, Emily Kathleen Presutti

Theses - ALL

Sexual victimization of college women is a significant public health concern on U.S. college campuses. Traditional research on the human stress response has focused on the "fight-or-flight" model, which may not adequately capture female-typical responses in stress-inducing situations. Using a mixed-methods design, we sought to determine whether the "tend-and-befriend" stress response serves as a potential correlate of sexual victimization among college women and examine whether it contributes additional variance beyond established correlates of sexual victimization such as alcohol use, history of sexual victimization, and involvement in campus party culture. The study was conducted in two phases. In Phase I, 128 …

Operational Context's Impact On Cockpit Behavior: Case Studies In Aviation, Nick Mehrdad Loghmani

Dissertations - ALL

This thesis examines instances where pilots in a tightly regulated environment, the modern airline cockpit, exhibit diverging responses when presented with identical information. Despite explicit standardization of procedures, instrumentation, and Crew Resource Management, observable patterns of operational divergence persist. The study adopts distributed cognition (Hutchins, 1995) as the primary lens and analyzes the crew–procedures–artifacts system using cockpit transcripts and flight data. Operational context is the evolving set of roles, procedures, cognitive artifacts (including automation), constraints, and environmental conditions, while the operational configuration denotes its time-indexed instantiation at moment t. Within this frame, the thesis documents when cues do—and do not—propagate …
