The Cul-De-Sac Paradox: The Relationship Between Walkability, Playability, And Children’S Physical Activity, Lydia Reader

McKelvey School of Engineering Graduate Student Theses & Dissertations

Walkability and playability are two constructs on how the built environment can support physical activity, the former most relevant to adults and the latter designed with children in mind. There are concerns that walkability and playability are intrinsically in competition with one another, with urban forms supportive of physical activity for adults detrimental toward the physical activity of children and vice versa. This thesis explores this conflict using agent-based modeling as a tool for refining the theoretical constructs behind playability and children’s physical activity. We examine the state of the current evidence for the relationship between walkability and children’s physical …

Data-Driven Staging Of Neurodegenerative Pathology Related To Alzheimer’S Disease, Thomas Earnest

McKelvey School of Engineering Graduate Student Theses & Dissertations

Alzheimer’s Disease (AD), the most common cause of dementia, is a dual proteinopathy exhibiting deposits of extracellular amyloid-beta (Aβ) and intracellular tau in brain tissue. Models which describe the spatial and temporal trajectories of these pathologies have been invaluable for understanding AD and have the potential to support diagnosis, disease monitoring, and treatment development. Disease staging systems, which provide protocols for assessing individual disease severity based on their extent of brain pathology, have been crucial for explaining and diagnosing AD. However, these systems have been primarily informed by post-mortem histological assessments and are not directly applicable to disease assessment in …

Openness To Experience And Creative Capacity Among Active First Responders, William Reagan

Walden Dissertations and Doctoral Studies

Because emergency services demand adaptive, creative problem-solving within procedurally rigid cultures, this study examined whether Openness to Experience predicted creative capacity among active first responders and whether age or tenure moderated that relationship. A cross-sectional design used N = 117 first responders from eight agencies. Openness was measured with the Big Five Inventory-2 (percentile ranks); creativity was assessed with the Divergent Association Task (DAT; n = 116) and the Consensual Assessment Technique (CAT; n = 111). Covariates were age, tenure, rank, gender, and, for 46 participants at one agency, a dispatch-derived operational exposure score. In the full sample, Openness did …

Sbirt Staff Education To Registered Nurses In The Emergency Department, Rosemary Thuet

Walden Dissertations and Doctoral Studies

Summary The project hospitals have, on average, 2,400 emergency department (ED) visits a month. Although patients receive a social screening, there are no specific assessments to determine if the person is at risk for alcohol use disorder (AUD). The lack of screening is a missed opportunity to provide a Screening, Brief Intervention and Referral to Treatment (SBIRT) assessment of over 2,400 patients a month or 48,000 people annually. Although several screening tools could be used for an SBIRT assessment, the recommendation of ED nursing leadership is to implement the tool known as the CAGE Questionnaire (Cut down, Annoyed, Guilty, and …

Dissecting Tumor Evolution And Immune Composition In Prc2 Loss (H3k27me3 Loss) Vs Retained Mpnst, Kuangying Yang

Arts & Sciences Graduate Student Theses and Dissertations

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas that arise sporadically or in the setting of neurofibromatosis type 1 (NF1). Although benign plexiform neurofibromas (PNs) are common in NF1, only a subset undergo malignant transformation, and the molecular events that define high-risk progression remain incompletely understood. A major axis of biological heterogeneity in MPNST is loss of Polycomb Repressive Complex 2 (PRC2), commonly detected through loss of H3K27me3 and frequently mediated by alterations in SUZ12 or EED. This dissertation integrates three manuscript-based studies to define genomic resources, tumor-intrinsic vulnerabilities, and immune microenvironmental remodeling in NF1-associated peripheral nerve sheath tumors, …

Unpacking Treatment Effect Heterogeneity In A Large-Scale Dropout Prevention Experiment, Thomas Dee, Chloe R. Gibbs, Rebecca Margolit-Chan, Lillian Morrell, James X. Sullivan

Upjohn Institute Working Papers

Timely high school completion is a critical step in successful transitions to post-secondary schooling and the labor market. This randomized controlled trial, deployed in two urban, disadvantaged school districts, tests the effectiveness of a mature and comprehensive student-support program on an unusually large scale (n=2,528). While overall effects on graduation rates are small and statistically insignificant, exploratory analyses reveal notable variation by site and over time, mirroring heterogeneity in treatment timing and program implementation. These findings highlight the challenges of scaling interventions and raise concerns about generalizing results from small-scale, single-site evaluations.

Poppers Maculopathy Due To Alkyl Nitriteinfused Candle: A Case Report, Tori Sayers, Murtaza K. Adam

School of Medicine Publications

Recreational inhalation of alkyl nitrites (“poppers”) is associated with a characteristic toxic maculopathy presumably due to ischemic changes in the central macula. Alkyl nitrite candles are available for purchase online and do not appear to be regulated. We report a unique retrospective case of vision loss following second-hand inhalation of vapor from a “poppers” candle in which a 29-year-old Hispanic male with no previous medical history presented with acute bilateral vision loss after attending a party at a nightclub. The patient denied sungazing, exposure to lasers, and a family history of inherited retinal disease. History was significant for use of …

Racial Trauma And Posttraumatic Growth: Implications For Counselors, Margaret M. Poandl, Nowoola Awopetu, Paul C. Harris Dr.

Journal of Counselor Preparation and Supervision

Racial trauma is ubiquitous among Black, Indigenous, and People of Color (BIPOC) and people who belong to other marginalized groups. It is likely that counselors will work with individuals who have experienced racial trauma. Aligned with the counseling profession’s values, counselors can take a strengths-based approach that incorporates facilitation of a historical trauma posttraumatic growth (HT-PTG) framework. This paper presents evidence-informed practices that can foster growth on individual and collective levels. A case example is provided that integrates individual- and collective-level interventions bidirectionally, along with implications for counselor training pedagogically, through supervision, and continuing education. Counselors can identify, encourage, and …

The Safe Fishbowl Model: Psychological Safety By Design In Counseling Skills Training, Mike Mariska

Journal of Counselor Preparation and Supervision

Skills training in counselor education can be constrained by performance anxiety, which may reduce participation, limit deliberate practice repetitions, and shift demonstrations to the instructor. This applied-practice manuscript introduces the SAFE (Structured Avatar and Feedback Experience) Fishbowl model, a simulation architecture designed to address performance anxiety while scaling participation. SAFE Fishbowl integrates rotating counselor roles, a real-time coaching loop, structured observation grounded in experiential learning theory, and purposeful debriefing. An implementation example for group counseling leadership skills is provided, along with adaptation guidance across multiple skill domains and delivery modalities. Descriptive course-evaluation feedback illustrates feasibility and perceived usefulness. Implications include …

A Mixed Methods Analysis Of Cacrep Accreditation Standards: Implications For The 2024 Cacrep Academic Quality Standards, David Moran

Journal of Counselor Preparation and Supervision

This embedded mixed methods study examined the frequency of CACREP standards cited as ‘not met’ by the CACREP Board of Directors and explored counselor educators’ experiences with program evaluation. Frequency analysis revealed that Section 4 standards were disproportionately cited, yet applied consistently across diverse institutional types and delivery formats. Qualitative interviews with 16 counselor educators identified four themes: The Paradox of Agency, Faculty Workload Challenges, Performative Compliance vs. Authentic Improvement, and Faculty Experience with Program Evaluation. Findings suggest that while accreditation decisions are unbiased, the evaluation process imposes substantial strain on faculty resources. These results have …

Integrating Consensual Non-Monogamy In Counselor Education: Practical Guidelines And A Pilot Descriptive Study, Yun-Zhuo (Zoey) Liu, Lena Salpietro

Journal of Counselor Preparation and Supervision

Consensual non-monogamy (CNM) is a prevalent and diverse relationship structure, yet mononormative assumptions persist in counselor training and practice, contributing to stigma and inadequate care. Research indicates that counselors’ CNM-specific knowledge and attitudes are critical to positive therapeutic outcomes (Schechinger et al., 2018), highlighting the need for clear guidance. In response, this paper presents Guidelines for Incorporating CNM in Counseling Curricula. Three domains are grounded in multicultural and social justice principles: foundational knowledge and terminology, challenging bias and promoting self-reflection, and application informed by attachment theory. Additionally, findings from a survey of counselor educators (N = 54) are presented. Results …

U.S. Service Member To Counseling Student, Nicole Marie Arcuri Sanders, Kellie Forziat-Pytel

Journal of Counselor Preparation and Supervision

This qualitative descriptive study examines the absence of military career pathways for licensed mental health counselors (MHCs) and the impact of this structural limitation on service members' career transitions. Findings indicate that both combat and non-combat veterans pursued mental health counseling due to personal service-related mental health experiences and dissatisfaction with available care while in service. Despite these challenges, many participants expressed a strong desire to continue serving their country as professional counselors. Over half of the participants reported separating from the military because no occupational role existed for licensed MHCs. At the same time, most indicated they would have …

The Expert Myth: Impostor Phenomenon And Research Identity In Counselor Education, Kristi B. Cannon, Kelly Coker, Trent Hepting, Lidian Ramirez-Fiol, Robyn T. Simmons

Journal of Counselor Preparation and Supervision

Imposter Phenomenon (IP) affects counselor educators across career stages, yet it is often conceptualized as an individual deficiency rather than a systemically reinforced experience. This article frames IP in counselor education through the lens of the Expert Myth—a systemic pattern within academic culture that reinforces the expectation that faculty must consistently present as fully knowledgeable, productive, and self-assured to be regarded as credible. We examine how institutional cultures, publish-or-perish pressures, and inadequate mentorship structures create and reinforce imposter feelings, particularly among marginalized faculty and those navigating researcher identity development. Drawing on existing literature, we propose that meaningful intervention requires systemic …

Modernizing Career Counseling In Counselor Education: A Conceptual Exploration, Yuhyun Park, Se Hoon Kim, Rasheed Adeyemo, Sarah Ebner, Mallory Redmond, Breeana Donayre, Carly Steves

Journal of Counselor Preparation and Supervision

Career development is often confined to a single course despite its relevance across counseling practice. This conceptual article reframes it as an integrative foundation for counselor preparation, supervision, and professional identity. It examines connections among work, mental health, education, disability, relationships, and social context across counseling specializations. The article also considers doctoral training and the ethical use of artificial intelligence in career-related practice. Recommendations address curriculum design, supervision, and future research on integrated career preparation.

The Lived Experiences Of Queer And Trans Counselor Educators In Cacrep Programs, Erin Pitts, Kathleen Brown-Rice, Maribeth F. Jorgensen

Journal of Counselor Preparation and Supervision

Queer and trans professionals historically experience discrimination, persecution, and oppression in the workplace. While counselor education has ethical and accreditation standards requiring multicultural inclusion and competence, there is limited research that explores the experiences of queer and trans counselor educators in the workplace. We used an interpretive phenomenological approach to explore the experiences of queer and trans faculty working in CACREP programs. Four participants completed semi-structured interviews, resulting in four themes: 1) career journey, 2) visibility matters, 3) if not us then who, and 4) work in progress. Implications for counselor education programs are offered related to identifying and addressing …

Developing Grief-Informed Counselors: A Reflexive Thematic Analysis Of Counselors-In-Training’S Learning Experiences, Katherine Atkins, Sonya Lorelle, Jennifer Slawson

Journal of Counselor Preparation and Supervision

Grief remains underrepresented in counselor education despite its relevance across the lifespan and its inclusion in the 2024 Council for Accreditation of Counseling and Related Educational Programs (CACREP) standards. This qualitative study explored how counselors-in-training (CITs) conceptualized grief and their developing professional role following participation in a structured grief education series. Eleven master’s-level CITs engaged in didactic instruction, experiential grief interventions, and reflective focus groups. Using reflexive thematic analysis, four interrelated themes were constructed that addressed grief conceptualization, counselor role development, integration of the personal self, and educational supports for grief competence. Findings reflected shifts toward relational, culturally responsive, and …

Political Interest And News Media Literacy Among University Students: Case Of The U.S.-Vietnam Comprehensive Strategic Partnership (2023), Nhat Anh Nguyen, Ngoc Thuy Duong Le

Journal of Media Literacy Education Pre-Prints

In today’s complex media environment, the ability to critically evaluate news plays an essential role in shaping political interest, especially among youth. Although media literacy has been extensively investigated in relation to civic outcomes, the particular link between news media literacy (NML) and political interest is still little known. This paper investigates this link among Vietnamese university students by means of the U.S.-Vietnam Comprehensive Strategic Partnership as a prominent foreign policy instance. Drawing on Potter’s (2004) cognitive model and Maksl et al.'s (2015) NML scale, this study primarily employs a quantitative approach using survey data (N = 410), complemented by …
