Predicting Telecommunication Customer Attrition Using The Hopfeld Neural Network Model., Benedict Kongyir, Emil Agbemade, Kelvin Njuki

Data Science and Data Mining

Customer churn prediction has become one of the crucial steps for customer retention. Telecommunication companies rely on loyal customers to make their proft. It is often very easy for customers to switch from one service provider to the other. To prevent or reduce the rate of customer attrition, there needs to be a model that can identify customers who are at risk of churning in the future in advance. Previous literature has shown that predictive models are efective in predicting customer churn. In this work, four tentative machine-learning models are built using data obtained from Kaggle on telecommunication customer attrition …

Survey data from 172 FGGCS’s was analyzed using bivariate correlational and regression analyses to answer four primary research questions: (1) Is there a statistically significant correlation between FGGCS’s level of imposter syndrome and academic resilience, (2) Is there a statistically significant correlation between FGGCS’s level of imposter syndrome and perceived wellness, (3) Are FGGCS’s level of academic resilience …

Comparative Analysis Of Metric And Non-Metric Ancestry Estimation Methods Of Maya Individuals, Griffon G. Binkowski, Channing Cook

High Impact Practices Student Showcase Spring 2024

Ancestry estimation finds its place in many fields of anthropology, including biological anthropology, osteoarchaeology, and paleopathology. A biological profile creates a framework for identity; with ancestry, it can aid researchers in determining the population group an individual is most genetically affiliated with. The heritability of dental traits makes teeth useful in estimating affinity. Ancestry estimation statistical programs using dentition, however, were originally developed upon limited and well- preserved databases, so archaeological Indigenous individuals are often grouped incorrectly as East Asian due to shared genetic traits. By using RStudio for anthropological statistical analysis, we aim to test the preservation bias and …

Terminological (In)Justice: Terminology And Reality In A Coordinated Community Response To Intimate Partner Violence, Julio Montanez Ma, Amy Donley Phd

Institute for Social and Behavioral Science (ISBS)

Definitions and terminologies are paramount for operationalizing the community-wide effort against intimate partner violence (IPV). However, definitions and terms that do not reflect reality are of little use. This is particularly true in IPV coordinated community responses that attempt to harmonize data collection and legal apparatuses at the federal, state, and local levels. Using qualitative (e.g., focus group and interview data from survivors, interviews with system actors) and quantitative data (e.g., Uniform Crime Reports) from a year-long study in a large southeastern county, the current study aims to answer the following research question: Do IPV-related terms (in data collection and …

Shifting Educational Paradigms: An Analysis Of Evolving Student Expectations Within A Reformed Physical Chemistry Curriculum, Kevin E. Morales

Undergraduate Scholarship and Creative Works

Students often hold negative expectations when enrolling in rigorous undergraduate courses. PhysicalChemistry is a challenging upper-level course for Chemistry majors; the course has a reputation as a demandingcourse that leads to students building negative expectations. This worsened when ambiguity existed in an instructor’s pedagogy. Not addressing those initial expectations of the students abates their motivation, which does not put them in the best place to learn, leading to poor academic performance. The course syllabus is often the first interaction a student has with the course; it can be a critical tool in (re)setting students' initial expectations and allows the instructor …

The Influence Of Foster Parent Characteristics On The Relational Permanence Of Foster Youth, Yogita Venkata

Honors Undergraduate Theses

Research suggests that lack of permanency is associated with an increased risk of aggression, mental instability, and delinquent behavior in children (Leve et al., 2012). A crucial component of permanency involves establishing stable connections, including relational permanence with peers and adults, which are believed to enhance the well-being of foster youth (Wekerle et al., 2009). Further, the literature suggests a relationship between a parent’s adverse traumatic experiences, their attachments to their own parents, and their ability to regulate their foster child’s relational permanence to supportive adults and peers. Foster parents who have experienced trauma are often insecurely attached to their …

From The Slime And Mud: Rumination As Fuel For Artistic Process, Olivia Van Natta

Graduate Thesis and Dissertation 2023-2024

This thesis examines my work to harness ruminative thinking as a driving force for my art practice. With a combination of drawing and painting in watercolor pencil, I activate and engage with rumination through the act of sublimation as defined in clinical psychology. Repetition of process and hand-rendered detail serve as outward channels for my obsessive cyclical thoughts. Based on my experience living with the physical effects of a hyperactive mind, I depict botanical life symbolically in an effort to communicate impressions of the bodily sensations associated with rumination, such as palpable tension, anxiety, or dread. In my research, I …

Prohibition In Sanford: Local Lives Questioning A National Narrative Presented Through Data, Discourse Analysis And Digital Mapping, Lindsey K. Yeazell

Graduate Thesis and Dissertation 2023-2024

Historiographical claims from state, regional, and national studies are tested through data sampling of Sanford Municipal Court Records; close readings of more than 200 Sanford Herald articles; and an oral history with a local museum curator based on family tradition.

This is an evidence-driven thesis. A thirty-percent sampling of 23,000 Sanford Municipal Court Records covering the Prohibition era (1920-1933) enables detailed analysis of alcohol-related arrest and enforcement patterns based on race, gender, …

Development Of An Objective Battery For Ptsd, Kathryn O'Dell

Graduate Thesis and Dissertation 2023-2024

Posttraumatic Stress Disorder (PTSD) is marked by avoidance, arousal, re-experiencing, and negative mood and cognition. To date, these symptoms are assessed using self-report measures (e.g., the PCL-5) and clinician administered assessments (e.g., the CAPS-5). While these are the present gold-standard assessments for PTSD, they still are prone to bias on behalf of both the administrator and the patient. Presently, there is evidence that individuals with PTSD perform differently than individuals without PTSD on certain cognitive tasks that measure attention bias and avoidance behaviors. As such, creating a battery of these tasks may be a viable route for objectively measuring PTSD. …
