2nd Place Research Paper: Shaping The Ape: Storytelling, Cultural Reflection, And Boundary Negotiation In Human-Ape Zoo Encounters, Abigail Bond Halling

Kevin and Tam Ross Undergraduate Research Prize

The typical Western zoo functions as a unique environment in which animals are frequently positioned as subjects of education and entertainment through the medium of storytelling. In this sense, the zoological institution can also be read as an extension of popular Western constructions surrounding nonhuman animals, particularly those who are symbolically charged characters in our collective imaginary– the great apes. Given the morphological, behavioral, and psychological similarities between humans and other great apes (chimpanzees, gorillas, and orangutans), nonhuman great ape enclosures at the Western zoo become spaces where humans are most radically confronted with navigating the boundaries of the “human-animal …

“Care Work” In Facilitative Mediation: Interactional Techniques For Emotional Support In The Context Of Conflict Resolution, Angela Garcia

Natural & Applied Sciences Faculty Publications

This paper investigates how facilitative mediators use “care work” techniques when participants display emotional or relational concerns during the session. Conversation analysis is used to analyze a pre-existing dataset of video-recorded small claims and divorce mediation sessions. Techniques the mediators used to do care work include reflection, topic refocusing, complimenting, role modeling, and coaching. The analysis shows how the trajectory of the talk in the mediation session is impacted by care work. The results are discussed in terms of their implications for the mediator’s role and the effectiveness of the interaction for the conflict resolution process in mediation.

The Role Of Artificial Intelligence In Reducing Internet Crimes Against Children, Malyssa Shaw

Student Scholar Symposium Abstracts and Posters

When generative artificial intelligence (AI) first surfaced and broke into the public sphere, my immediate concern was in its development, implementation, and harmful applications. I was not surprised when deepfake technology rapidly advanced alongside these new developments and impacted women and children worldwide. Disproportionately, they have been made victims of intimate media forgery as early as the 1990s, with an unprecedented uptick in recent years as a direct result of these developments. In response, I wrote "Deepfake, Real Harm: Protecting Children in the Age of AI", analyzing data specifically regarding child sexual abuse material (CSAM) created with artificial intelligence while …

Introduction To Sociology: Deviance And Crime, Dr. Marcia Morrison Ph.D.

Open Educational Resources

Abstract

This paper explores the multifaceted concepts of deviance and crime by synthesizing major theoretical perspectives and contemporary research findings. Beginning with the fluid and culturally contingent nature of deviance, the discussion highlights how social norms, historical context, and power structures define what is considered deviant behavior. It examines the influence of economic elites on moral and legal standards, drawing on Marxist analyses, and considers the impact of societal labeling on personal identity through Lemert’s labeling theory.

The paper then delves into biological foundations of criminality, reviewing Lombroso’s atavism theory and modern research on genetic predispositions, including twin, adoption, and …

Grief As Slip: (How Little I Show) An Exploration In Clay, When Words Are Not Enough, Michelle A. Smith

Masters Theses, 2020-current

Grief as Slip (how little I show) implies that even as we acknowledge our mortality and the fleeting nature of life, we still only reveal a fraction of our true selves or our deeper realities. The ceramic artwork in this exhibition carries and conveys a journey through the present and remembered emotions of the artists’ personal narrative. By juxtaposing the tactile nature of clay with the ethereal quality of human experience, Smith contemplates the profound interplay between material transformation and emotional resilience. The exhibition’s intent is to translate the essence of complex emotional states into abstracted forms so they can …

Psychological Treatment Behind The Walls:Insights From The Inside, Rogelio Serrano

Psychology Division Scholarship

Repeated eras of mass incarceration, criminalization of marginalized communities, and substance use policies have created a revolving door of justice involved populations. The ever-increasing prison population has repeatedly become the largest contingency of mental health clientele for an overburdened mental health system. Those who work with formerly incarcerated individuals in the community often don’t know the unique set of challenges faced by practitioners within the system. Increased understanding and coordination of care can offer opportunities for sustained recovery and reduced levels of recidivism. In this presentation participants will learn about the unique insights on mental health treatment that can be …

Love In The Time Of Dating Apps: Exploring Latino Young Adults’ Experiences Constructing Online Identity, Partner Preferences, And Plans For Happily Ever After, Dakota Z. Ross-Cabrera

Dissertations, Theses, and Capstone Projects

This dissertation examines how Latino young adults navigate dating apps; construct their dating app profiles, select partners and develop preferences, and conceptualize their futures. While earlier dating app research explores these themes with quantitative data or with non-Latino samples, the qualitative experiences of Latino young adults have been broadly excluded. Latinos are a large portion of the dating app market, and their relationships, outcomes, and future family formation are integral to understand. Drawing on 60 qualitative interviews with Latino young adult dating app users, I find that app users encounter five stages of dating app usage including constructing and often …

Principal Agency 50 Years After The Lau Decision: Building And Sustaining Bilingual Education Programs For Asian Languages, Kevin M. Wong, Zhongfeng Tian

Education Division Scholarship

This study examined how three champion principals of Asian language dual language bilingual education (DLBE) programs—Cantonese, Korean, and Mandarin—in California have navigated the oscillating language-in-education policies after the Lau decision. We explored principals' various roles through a lens of agency in a social justice leadership framework, specifically considering the opportunities and challenges for agentive leadership from three different phases: foregrounding and engaging, planning and implementing, and evaluating and sustaining. Findings demonstrate that the success of DLBE programs goes beyond the overarching language policies that supposedly enable bilingual education; rather it hinges on the bottom-up commitment, collaboration and resilience of principals, …

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

Early Childhood Language Gains, Kindergarten Readiness, And Grade 3 Reading Achievement, Jessica A.R. Logan, Shayne B. Piasta, Kelly M. Purtell, Robert Nichols, Rachel E. Schachter

Department of Child, Youth, and Family Studies: Faculty Publications

In this preregistered study, we used latent change score models to address two research aims: (1) whether preschool-aged children's language gains, over a year of early childhood education, were associated with later performance on state-mandated, literacy-focused kindergarten readiness and Grade 3 reading achievement assessments, and (2) whether gains in language, a more complex skill, predicted these outcomes after controlling for more basic emergent literacy skills. There were 724 participating children (mean = 57 months; 51% male; 76% White, 12% Black, 6% multiple races, and 5% Hispanic or Latino). We found that language gains significantly predicted kindergarten readiness when estimated in …

Psychology Faculty Articles and Research

Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg’s 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across …

Patterns Of Classroom Organization In Classrooms Where Children Exhibit Higher And Lower Language Gains, Laura Cutler, Rachel E. Schachter, Clariebelle Gabas, Shayne B. Piasta, Kelly M. Purtell, Nathan P. Helsabeck

Department of Child, Youth, and Family Studies: Faculty Publications

Previous research suggests that the ways in which early childhood classrooms are organized may facilitate children’s language learning. However, different measures of classroom organization often yield inconsistent findings regarding child outcomes. In this study, we investigated multiple aspects of classroom organization across two time points in classrooms where children made varying language gains. Using a purposeful sample of 60 early childhood classrooms, 30 in which children made higher language gains and 30 in which children made lower language gains, we explored the organization of the physical classroom literacy environment, classroom management, classroom time, and classroom activities. Research Findings: Results indicated …

Historical Trauma: Literary And Testimonial Responses To Hiroshima, Mariam Ghonim

Theses and Dissertations

The concept of trauma is controversial in literature. While one may be able to come up with ways to describe trauma in fiction, representing historical trauma is a hard task for writers. Some argue that trauma can not be described through those who did not experience it, while others claim that, provided some elements are added, one can represent trauma to the reader. This thesis focuses on twentieth-century historical traumas related to a nuclear catastrophe and explores the different literary and testimonial responses to the catastrophic man-made event of Hiroshima (1945). In this thesis, Kathleen Burkinshaw’s historical fiction The Last …

Coparenting Support In The Context Of Difficult Children: Mother And Father Differences, Victoria J. Johnson, Dongho Choi, Lorey A. Wheeler, Patty X. Kuo

Department of Child, Youth, and Family Studies: Faculty Publications

While parenting children with difficult behaviors can intensify stress within the entire family system, families may lean on other familial relationships to mitigate that stress. The coparenting relationship is known to play a key role within the family system for child outcomes and familial interactions, but it is not clear whether it eases the stress and challenge of raising a difficult child, nor how that plays out differently for mothers versus fathers. Ninety-six couples (89.7% married) parenting young children (Mean age = 3.22 years) were included in this study. Using cross-sectional and aggregated daily response data, actor–partner interdependence models were …
