A Symbolic Model Of Proof Acquisition In Act-R, Beckett Morris, Kerstin Haring

DU Undergraduate Research Journal Archive

Learning to construct mathematical proofs—formal arguments demonstrating the truth of a mathematical statement using logical deductions and previously established facts—is one of the most challenging skills in STEM education. This research aims to build the foundations for a symbolic cognitive model, using the ACT-R cognitive architecture and implementing in Python with the pyactr package, to explore how different proof strategies can be thought through with only symbols and rules. The model observes simple proofs, and its abilities are assessed based on its generalization capabilities, efficiency, and error patterns. By developing and analyzing such a model, this research provides new insights …

Impact Of Eating Disorder Type On General Population Perceptions Of Stigma And Likelihood Of Comorbidity, Gabri Notov, Grace Schroeder, Kaz Skelton, Kevin Summers, Sarah Huff

DU Undergraduate Research Journal Archive

Eating disorders carry a significant risk of mortality, necessitating further research. Previous work has examined how stigma influences treatment seeking in other mental health conditions, creating a potential area for improving disordered eating outcomes. Additionally, prior meta-analyses have discovered high comorbidity of other mental health diagnoses with disordered eating. Some work has attempted to examine the perception of comorbid mental health problems alongside eating disorders, but this construct has not been studied in depth within general populations. To date, no work has simultaneously examined stigmatization and knowledge of common mental health problems with disordered eating in this population. This study …

Investigating The Moderating Roles Of Adolescent Peer Relationship Difficulties And Prosocial Behavior On The Relationship Between Triangulation And Adolescent Emotional Symptoms During Parental Divorce, Taylor Kalei Demotta

Clinical Psychology Dissertations

The divorce process is a stressful, transitional period that is widely experienced by families in the United States. This process incites a variety of stressors and deleterious family dynamics that impact children and adolescents. The divorce literature has identified parental conflict as a significant contributor to youth outcomes following divorce. Therefore, researchers have aimed to investigate the specific dynamics occurring during interparental discord that may influence youth. Triangulation, or the involvement of children in parental disagreements, has been found to mediate the relationship between parental conflict and adolescents’ internalizing symptoms. Adolescents may be particularly vulnerable to triangulation due to increases …

Behind The Bar: Empathy Burnout's Impact On Lawyers' Job Competency, Eva L. Newkirk

Honors Projects

It is well established within psychological literature how burnout develops among human service professionals including nurses, therapists, police officers, and first responders. Despite facing the same kinds of risks for burnout development by helping professions, especially trauma and stressful client relationships, the development and consequences empathy burnout have been under-researched in lawyers. This project aims to explore existing literature around burnout and empathy as related to job competency in legal professionals and develop a survey that explores empathy as a potential indirect mediating variable from burnout to employee engagement. The article additionally discusses the pathway from second-hand trauma to empathy …

The Worker Voice Gap: How Much Say Do Workers Want—And How Much Do They Actually Experience?, Alexander Hertel-Fernandez, Thomas A. Kochan

Upjohn Institute Policy Papers

•The worker voice gap—the difference between the influence that workers want and what they experience—is very large. Nearly three-quarters of American workers want more voice at work than they currently have in three key areas: 1) compensation, 2) working conditions, and3) use of new technologies at work.

• The voice deficit is largest for compensation, but majorities of workers also express voice gaps over working conditions and the use of new technologies in their workplaces.

•Although voice gaps are relatively widespread, women tend to report larger voice gaps than men, and younger and middle-aged workers tend to report larger gaps …

Internalized Homophobia As An Influence On Participation In Hiv Prevention Among Young Men Who Have Sex With Men (Ymsm), Kasey I. Brazee

Honors Scholar Theses

Stigma is a known barrier to accessing preventative services for human immunodeficiency virus (HIV), however, the types of stigmas involved in this relationship remain not well defined. Homophobia, or negative attitudes directed towards homosexuality, is a particularly important type of stigma considering the disproportionate effect of HIV on men who have sex with men (MSM). Young MSM (YMSM) are especially impacted, making them a key population in the context of HIV prevention research.  Internalized homophobia, which refers to homophobia that one directs towards themselves, is under researched regarding its role in participating in HIV prevention. In this study, we aimed …

The Impact Of Mnar Attrition On Estimation Of Latent Growth Curve Models With Binary Observed Variables, Jason T. Newsom, Brian T. Keller, Mallory R. Kroeck, Nicholas A. Smith

Psychology Faculty Publications and Presentations

A Monte Carlo simulation was used to evaluate the performance of latent growth curve (LGC) modelswith binary observed variables when the attrition pattern was missing not at random (MNAR) for fivetime points. Parameter and standard error biases for three estimation methods were compared:weighted least squares with mean and variance adjustment (WLSMV), categorical robust marginal max-imum likelihood (categorical MLR), and Bayes. The results indicated that robust diagonal weightedleast squares paired with multiple imputation (MI) performed best when values were missing at ran-dom. When data were missing not at random, Bayesian estimates performed best.

Women Self-Help Groups As Drivers Of Community Development In Rural Kenya, James Kariuki, Bhoke Chacha

Journal of Global Awareness

Self-Help Groups (SHGs) are informal grassroots associations of people who have similar objectives and concerns working cooperatively and collectively to meet their needs and improve their living conditions. SHGs are known to contribute towards the development and welfare of their members. This paper examines the role of SHGs in community development in Kenya with a focus on selected women groups in Migori and Makueni Counties. The study adopted a mixed research approach that provided both qualitative and quantitative data, and it was anchored on two interrelated theories of community development: empowerment theory and social capital theory. The researchers interviewed 80 …

Lessons Learned In Providing Infant And Early Childhood Mental Health Consultation During The Covid-19 Pandemic, Rashele Wade

Journal of Global Awareness

Access to quality childcare is a protective factor from lifelong issues such as school failure, school drop-out, and incarceration. Conversely, preschool suspension and expulsion are significant risk factors. Evidence-based interventions, such as Infant and Early Childhood Mental Health Consultation, aim to reduce and eliminate the incidence of preschool suspensions and expulsions. The COVID-19 pandemic disrupted access to quality childcare for many children across the country and globally. This study utilized a qualitative action research approach and generic qualitative inquiry to examine the research question, “How can we improve Infant and Early Childhood Mental Health Consultation through lessons learned during the …

Journal of Global Awareness

Cancer cases have been on the increase globally, and this has led to economic burden on the affected households. One way of reducing the cost of care is through home-based care by informal palliative caregivers who include family members, friends, and other people assigned by the family members to take care of the patient. The objectives of this study were to assess the status of the mental wellbeing of palliative caregivers of cancer patients; to examine the relationship between the ability of the patient to cope with cancer diagnosis and the mental wellbeing of the caregiver; and to investigate the …

Navigating Burnout: The Role Of Workplace Support For Social Work Clinicians, Melanie Fulton

Journal of Global Awareness

The shortage of mental health workers is a growing concern in the United States, and social workers a substantial portion of employees who work with individuals with mental health concerns. This shortage stresses the importance of studying factors that impact burnout for mental health clinicians, particularly social work clinicians. While burnout among social workers in some settings have been documented in the literature, less research has focused on independently licensed clinical social workers in private practice. This study had participants complete a survey to examine the relationship between workplace support, burnout, and professional fulfillment among this population (N = 57). …

Heroism As Emotional Integration: A Process Model Of Emotion-Driven Heroic Action, Scott T. Allison

Heroism Science

Heroism is often framed as the expression of prosocial motivation fueled by positive emotions such as empathy, compassion, and moral elevation. This perspective, however, overlooks the complex emotional dynamics that characterize high‑risk, morally consequential action. This article advances a process model of heroism as emotional integration, involving the dynamic coordination of multiple and often competing emotions—including fear, anger, compassion, and moral concern—under conditions of uncertainty and threat. Drawing on research in heroism studies, positive psychology, and affective science, the model distinguishes heroism from ordinary helping by emphasizing emotional conflict, regulatory processes, and identity‑based commitment. It further differentiates rapid, intuitive …

Clustering And Switching As A Scoring System In Indonesian Three Word Fluency Tests, Heni Gerda Pesau, Gilles Van Luijtelaar

Makara Human Behavior Studies in Asia

The number of correctly produced words is the primary output variable n most verbal fluency tests. The examination of the number of clusters and cluster size achieves a more in-depth analyses of cognitive aspects and processes. We propose a scoring system for phonemic, semantic, and emotion word fluency tests in the Indonesian context. This study aimed to determine the underlying cognitive constructs of the participants, including the clustering and switching indices, using principal component analysis (PCA). A total of 150 participants were included, and the tests were administered online following a previously validated protocol. The three fluency tests loaded different …

Numb., Anna Rapson

Masters Theses

Social media platforms, from their conception, posed a break in the lived experience of the average human being’s day to day routines. Although access to information has always been shaped by portals into other lived realities—through photojournalism, print legacy media, news broadcasts both on radio and television—social media has posited a novel phenomenological architecture where borders between embodied reality and perception of lived experience are simultaneously blurred and reinforced. This morphed duality of consciousness positions the body and mind in tension, deconstructing pre-social media conceptions of the ontology of lived experience. In a digital world shaped by limitless input by …

Finding A Way Out Of The Filter Bubble: The Confusion Of A Heavy Social Media User, Longwen Miao

Masters Theses

This thesis studies how algorithmic recommendation systems reshape visual perception, aesthetic judgment, and the construction of selfhood within contemporary digital culture.

Everything begins with the experience of repeatedly encountering algorithmically recommended content on everyday digital platforms. On these platforms, images, sounds, and social interactions are continuously selected, repeated, and reorganized by predictive systems, forming an environment in which perception is constantly structured and adjusted.

From this observation, the research raises two central questions: how do algorithmic recommendation systems reshape visual perception, aesthetic judgment, and self-recognition, and how might these systems be intervened in or made perceptible through artistic practice? Within …

Always More To Explore: Play And Resilience In Community-Based Artmaking, Charlotte T. Faubert

Masters Theses

The following research investigates the ways in which material exploration in community-based artmaking spaces fosters learning through play and creative resilience. Using teacher-based action research, three visual arts workshops were designed, conducted, and reviewed in order to understand how community-based teaching strategies that center material exploration impact these two components of social emotional growth in elementary-aged art students. The conclusions drawn from this research indicate that material exploration, learning through play, and creative resilience are elements within community-based artmaking that form an ecosystem of learning, with all three phenomena feeding off of one another in a non-linear capacity. Additionally, it …

The Educational Gender Gap Explored Through The Lens Of Hegemonic Masculinity, Marcell V. Csikos

University Honors Theses

Women's college attendance skyrocketed with the passing of Title IX, and by the eighties, college campuses featured men and women at an even fifty-fifty split. Today, women make up over fifty-seven percent of college students. It is not a new phenomenon, studies and surveys have shown that women are doing better at school for decades, but they rarely tie men's underperformance to the concept of masculinity. The study of hegemonic masculinity is an overarching theory that looks at the values, rules, and dynamics that men have to follow in order to keep their social status. This literature review uses said …

Waterway: A Steam-Based Therapeutic Device System, Mingyuan Dong

Masters Theses

Across history and global cultures, water has played a central and often spiritual role in practices of care, from cleansing rituals to saunas and steam therapies. Yet, within contemporary product design, water is typically treated as a utility rather than as an experiential material capable of shaping perception, attention, and well-being. This thesis, Waterway, investigates how water, specifically in its steam state, can be designed as both a therapeutic medium and a ritualized experience that engages the body and mind.

Waterway proposes a steam-based wellness system that addresses physical pain and somatic discomfort while cultivating slower, more attentive interaction. Rather …

A Psycho-Spiritual Transformation In Covid-19 Crisis Narratives: A Comparative Study In Indonesia And Pakistan, Heru Prakosa, Nurlaela Widyarini, Johanes Seno Aditya Utama, Juan Carlos

Makara Human Behavior Studies in Asia

Although the COVID-19 pandemic ended as a global health emergency, its psychosocial legacy persists in many communities. This study examines how religion and spirituality support recovery in Indonesia and Pakistan by shaping crisis narratives. Faith-based language is treated as psychosocial data and interpreted through its functions in meaning-making, emotion regulation, social connection, value anchoring, and action commitment using Psycho-Spiritual Transformation (PST) as a guiding framework. Open-ended responses were collected from 274 participants via an online survey in July 2021 (Indonesia n = 236; Pakistan n = 38). Across both contexts, narratives typically moved from pressure and inner conflict toward spiritual …
