Exploring Autistic Children’S Play Cycles Using The Play Cycle Observation Method (Pcom), Eleanor C. Mugford, Pete King

International Journal of Playwork Practice

The Play Cycle Observation Method (PCOM) enables researchers to observe and record the process of play based on the theory of the Play Cycle. While the PCOM has been used with both video footage and in real-time observation of neurotypical children, it has not previously been applied with neurodivergent children. This study involved ten one-hour naturalistic PCOM observations with nine autistic children during play sessions. The results demonstrated variability in play processes, with several styles of play behaviour observed, including differences in how play was initiated, sustained, and terminated. The findings both corroborate and challenge strands of the existing literature …

Problematic Social Media Use’S Association With Social Anxiety And Neural Responsiveness To Reward From Social Media Feedback, Kaylee Mercer

All NMU Master's Theses

Social media has become increasingly relevant, especially among young adults. Those with social anxiety are more at risk for problematic social media use. Social media increases activity in the brain's reward centers. A common measure of the neural correlates of reward is the event-related potential, reward positivity (RewP) in EEG. Heightened RewP is associated with greater social anxiety. Problematic social media use is also associated with greater social anxiety. The neural correlates of reward elicited from social media use have yet to be adequately explored. The current research used continuous high-density electroencephalography to measure reward sensitivity when viewing positive or …

Improving Cannabis Sativa's Phytoremediation Capabilities Of Forever Chemicals Through Microbial Inoculations, Tyler S. Jolin

All NMU Master's Theses

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that pose ecological and human health risks due to their resistance to degradation and potential for bioaccumulation. Phytoremediation has emerged as a potential strategy for mitigating PFAS contamination, and plant-microbe interactions may influence contaminant uptake and transport within plant systems. These studies investigated microbial inoculation methods and examined whether Bacillus subtilis could influence the uptake and distribution of perfluorooctane sulfonate (PFOS) in hydroponically grown hemp (Cannabis sativa L.). Plant height and stem diameter growth rates and biomass accumulation were compared across treatments with and without PFOS exposure and microbial inoculation. PFOS …

Deep Learning Based Approaches For Low Cost Defense Detection, Adele J. Noel-Rickert

All NMU Master's Theses

Pulmonary fibrosis is a progressive interstitial lung disease characterized by the accumulation of fibrotic tissue within the lungs, leading to impaired respiratory function and reduced quality of life. Early detection is important for disease management; however, accurate diagnosis often relies on high-resolution computed tomography (CT), which may not be accessible in all clinical settings. Chest radiography provides a lower-cost and widely available imaging modality, but interpretation of chest X-rays for fibrotic disease can be challenging due to subtle radiographic patterns and overlapping anatomical structures. This thesis investigates the use of multimodal deep learning techniques to assist in pul- monary fibrosis …

Tough Love Or Just Tough?: The Effect Of Juvenile Military Bootcamps On Adolescent Externalizing Behaviors, Paris Labadie

Honors Theses

Externalizing behaviors, which are mental health problems manifested as outward behavior, have negative impacts on the environment and relationships (Liu, 2004). They include traits such as impulsivity, aggression, and substance use. Externalizing behaviors are more common in justice-involved youth compared to those who were not involved. Interventions for justice-involved youth, such as military boot camps, offer an alternative to incarceration and provide rehabilitation opportunities and routine. Theoretical research suggests military boot camps are problematic, citing the ineffectiveness of “scared straight” tactics. To date, there are few studies examining changes because of completing boot camps. There are also no studies examining …

Detection And Quantification Of Allergen Cross-Contact In Shared Frying Oil Using Targeted Mass Spectrometry, Francisca Asigri

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Cow’s milk and egg allergies are prevalent IgE-mediated food allergies that pose significant public health concerns worldwide. Although strict avoidance remains the primary management strategy, unintended exposure can still occur through allergen cross-contact, particularly in commercial and industrial food operations that utilize shared frying oils. The objective of this study was to identify and quantify allergen transfer in shared frying oil and assess the robustness of existing targeted mass spectrometry methods (LC-MS/MS) for detecting milk and egg proteins in heated oil matrices.

Heated oil spikes were developed by incorporating non-fat dry milk (NFDM) and whole egg powder (WEP) into oil …

Workplace Identity Disclosure: A Systematic Review And Psychometric Meta-Analysis Of Measurement And Correlates, Daniel Ryan Charles

Theses and Dissertations from DePaul University

Workplace identity disclosure (WID) is a central process through which employees manage concealable stigmatized identities at work, yet the empirical literature is fragmented by inconsistent construct labels, varied measures, and uneven coverage across identity domains. This dissertation conducted a systematic review and psychometric meta-analysis of quantitative studies examining WID and related constructs. WID was defined as an umbrella construct encompassing disclosure-related behaviors through which employees make a concealable stigmatized identity known, more visible, or less hidden at work. The final review included 37 reports and 38 independent samples. Corrected bivariate associations were estimated for construct pairs represented by at least …

Continuum Observations Of Water Maser Sites, Aman Khan

Theses and Dissertations from DePaul University

Stars form in cores deep within cold (10 K) clouds of hydrogen gas. As material is accreted onto the central object inside these cores (the protostar), powerful outflows that channel mass away from the protostar are also launched. The launching mechanism for these outflows is still not fully understood. This thesis presents observations of the 22 GHz continuum emission from two star-forming regions, NGC 7129 FIRS2 and IC 1396-n. The immediate aim of these observations is to find where this continuum emission is coming from, particularly if it is free-free emission from a jet or outflow, and the long term …

“Affirming Minds, Lives, And Bodies”: Secondary English Teachers’ Perceptions Of Critical And Humanizing Antiracist Pedagogy In Urban Schools, Jennifer Leigh Ankerberg

Theses and Dissertations from DePaul University

This qualitative study explores how White secondary English teachers perceive and enact antiracist approaches when teaching a prescribed, canon-based curriculum to students of color. Drawing on in-depth, semi-structured interviews with four teachers in a large Midwestern urban district, the study finds that the participants, aligned with their district’s stated philosophies and experiencing significant instructional autonomy, leveraged professional and contextual knowledge to adapt and supplement mandated curriculum. Guided by critical pedagogy and critical literacy frameworks, the analysis reveals how teachers’ values, beliefs, and dispositions grounded an assemblage of embodied antiracist, critical, and humanizing pedagogies. The participants’ curricular and instructional choices reflected …

Socio-Informed Policing: Applying Bourdieu To Mandatory Police Reform Training, Neil T. Shelton El

Theses and Dissertations from DePaul University

Contemporary U.S. police reform policies rely on officer training as a primary mechanism to address issues of law enforcement legitimacy and accountability. Yet, despite legitimacy-based curricula such as procedural justice, research indicates that this training struggles to produce durable changes in police practice. This qualitative study used a phenomenological approach to examine officers’ perceptions of mandated reform-oriented training. Drawing on Bourdieu’s theory of practice, the study conceptualized police training as a sociological process shaped by habitus, forms of capital, and the policing field. Data were collected from six officers in a large urban police department to examine how they internalize, …

The Relationship Between Culturally Based Mentoring And Academic Persistence In African-American And Latino Male Community College Students, Corey M. Williams

Theses and Dissertations from DePaul University

Men of color, particularly African American and Latino males, continue to experience disproportionately low rates of persistence and degree completion in community colleges. While prior research has often focused on individual deficits, less attention has been given to the institutional conditions and relational supports that shape student success. This study examines how culturally grounded mentoring influences persistence, student involvement, and overall student success among men of color in a community college context. Grounded in Tinto’s theory of student persistence and Astin’s theory of student involvement, this qualitative phenomenological study explores the lived experiences of participants engaged in a structured mentoring …

University Oral Hygiene Behaviors Compared To The National Population, Noura Naami, Jordan Monteiro, Trisha Jois

Undergraduate Student Symposium

Maintaining optimal oral health is essential for preventing dental caries, periodontal disease, and systemic complications. However, the combined effects of brushing, flossing, and mouthwash, which are common oral practices, remain incompletely understood. While each practice has been studied individually, there is limited data existing that evaluates how different brands and the frequency of use interact to influence the oral environment. In this study, we use a cohort of 40 university aged individuals to examine oral hygiene behaviors compared to the general U.S. population. In regard to flossing, national data suggests that this behavior is the least consistently utilized method of …

The Effects Of Gender Crime Congruency On Jurors' Decisions And Confidence, Elizabeth Avila

Undergraduate Student Symposium

A basic principle of the U.S. court system is that every individual has the right to a fair and unbiased trial. While this is the ideal, it is not always reality. Jurors come in with their own beliefs and attitudes before the trial starts. These preconceived beliefs can jeopardize the integrity of the trial. An example of these beliefs is gender stereotypes. Gender stereotypes can influence a juror's attitude towards a defendant, to either have a more negative or positive view on whether the defendant's gender matched the nature of their crime. This is called gender crime congruency. In this …
