Communication & Theatre Arts Theses

This thesis examines the communication challenges faced by migrants and their impact on acculturation using a new approach. The study analyzed autobiographical memories of immigrants’ communication to explore both positive and negative experiences over time. The study extends previous intercultural communication research by using the Life-Line Interview Method (LIM) (Assink & Schroots, 2010) to collect autobiographical narratives from twelve participants about their communication journeys. The findings reveal consistencies with past intercultural communication research insofar as uncertainty and identity problems were pervasive, but also positively extends past research arguing that supportive environments, characterized by culturally responsive educators and peer networks, play …

Investigating Gender Differences In Intimate Partner Violence Using Gendered General Strain Theory, Stephanie Victoria Dragon

Sociology & Criminal Justice Theses & Dissertations

Intimate partner violence (IPV) is a public health concern impacting communities and criminal justice systems. Nationwide IPV prevention and reduction policies were emphasized in the media during the aftermath of COVID-19 specifically regarding the identification of IPV offending behaviors through law enforcement screening tools. Research on IPV offending has clearly established a link in offenders exerting methods of power and control to harm an intimate partner through verbal abuse, coercion, sexual violence, and physical violence. Further, research also identified significant disproportional experiences of lethality in female victims at the hands of an intimate partner. However, criminological theories outside of control-based …

Additionally, PSA tests often yield false positives or negatives, and biopsies carry significant side-effects and discomforts. Therefore, there is a pressing need for novel, non-invasive diagnostic approaches. MicroRNAs (miRNAs) have emerged as promising biomarkers for prostate cancer due to their dysregulation in malignant cells …

Compulsory Sterilisation And Reproductive Injustice In India: The Global Impact Of The American Eugenics Movement, Marina Cortez

Institute for the Humanities Theses

On 8 November 2014, Dr RK Gupta performed eighty-three tubal ligations at a makeshift clinic in Bilaspur, India — thirteen of which resulted in death. The women, most of whom belonged to the Dalit or “untouchable” caste, were recruited by family planning agencies, lured in by cash incentives or other gifts in exchange for sterilisation. Sadly, however, the Bilaspur tragedy does not exist in isolation — but rather belongs to an extensive history of government-sponsored abuse, the majority of which has been directly led by white, Western powers. Funded by the New York-based Population Council, India was one of the …

School Librarians Transferring What They Learned In Their Preparation Programs To Practice: Three Case Studies, Carl Adrian Harvey Ii

STEMPS Theses & Dissertations

ALA/AASL/CAEP standards are used to determine what preservice school librarians in nationally recognized programs are taught in their preparation programs. School librarian preparation programs follow standards to ensure their graduates are prepared and ready for their positions. The standards provide consistency in how school librarians are prepared across the country as preparation programs must provide data to demonstrate how their students have met those standards for national recognition. However, once the students complete the program and move on to their positions in K-12 schools, what happens? Do students transfer what they have learned in their preparation programs? What challenges or …

Low Dissolved Oxygen Operation Enhances Biological Phosphorus Removal In Wastewater Treatment, Haley Morgan

Civil & Environmental Engineering Theses & Dissertations

Biological phosphorus (bio-P) removal occurs when bacteria are exposed to anaerobic/aerobic conditions that stimulate polyphosphate-accumulating organisms (PAOs) to uptake phosphorus. In most treatment plants, dissolved oxygen (DO) concentrations in the aeration tanks are commonly at or above 2.0 mg O₂/L, which is often referred to as the most optimal aeration condition for bio-P. If bio-P can happen efficiently at lower DO (< 0.3 mg O₂/L), then the energy demand of aeration can be decreased appreciably. This research was conducted in a biological nutrient removal (BNR) pilot plant to assess the performance of bio-P at progressively lower DO operation. This …

A Formal Simulation Model For Discrete Rate Simulation, Thomas J. Tracey

Electrical & Computer Engineering Theses & Dissertations

Simulation is an essential tool for virtualizing systems by creating a representative model of real or hypothetical systems and observing how they change over time. Two predominant simulation paradigms include Discrete Event Simulation (DES) and Continuous Simulation, which both have their strengths and weaknesses. DES does not handle continuous state variables, while continuous simulation handles continuous state variables but encounters errors where these variables have discrete changes in their behavior. This difficulty between the two predominant simulation paradigms prompted the creation of a new simulation paradigm to cover this gap: Discrete Rate Simulation (DRS). DRS as a simulation paradigm focuses …

Beyond The Institution Of Motherhood: Shifting The Paradigm, Gabrielle Wilson

Graduate Research Conference (GSIS)

This paper explores declining birth rates as a global act of resistance and reclamation by women and birthing individuals against hyper-masculinized institutions, using South Korea's 4B movement as a case study. The 4B movement, which rejects marriage, childbirth, romance, and heterosexual relationships, represents a paradigm shift challenging entrenched gender norms, state control, and systemic inequities. It exemplifies a global phenomenon as similar movements gain traction in the U.S., Japan, and beyond, amidst rising conservatism and declining fertility rates. Framing this analysis with intersectionality, Feminist IR theory, and Kuhn’s paradigm shift model, the paper argues that this resistance signifies a transformative …

Modeling The Impact Of Nato Policy Actions On Taliban Disinformation Campaigns With Lotka-Volterra Models, Timothy Tarter, Bella Santos

Graduate Research Conference (GSIS)

In this paper, we use an adaptation of the Lotka-Volterra Predator-Prey framework (via Affilit Et. Al.) to model the relationship between Taliban disinformation campaigns and NATO’s attempts to counter them. We find that aggression is a significantly preferred strategy over stagnation; this result should prompt decisionmakers to take strong stances against disinformation campaigns while maintaining a healthy defense against retribution. This leads us to propose the NATO Afghan Youth for Change program, which provides scholarships to individuals throughout the Afghan diaspora to become NATO influencers - a role which will both advance their personal goals and mitigate the spread of …

Embedding And Enabling Multi-Domain Combat Capabilities With Partners And Allies: A Joint Concept Proposal, Nathan Colvin, Aljoša Kaučevič, Randall Mercer

Graduate Research Conference (GSIS)

Future military operations will rely upon a coalition partnership’s ability to conduct regional and global operations across all domains. Currently the US has the most robust multi-domain skill sets of any existing military force, but the US cannot be solely responsible for operations around the globe. To do so would be geopolitically and economically infeasible. An answer may be to build cohesive coalition force units capable of combining localized capabilities and specialized US global competencies. The ability to respond to any type of threat through the synergy of coalition strengths will act to deter regional threats throughout the cooperation, competition, …
