Horticulture Faculty Publications and Presentations

Introduction Excessive nitrate accumulation in leafy vegetables poses health risks and indicates inefficient nitrogen use in conventional agriculture. While nitrogen metabolism has been extensively studied, the molecular mechanisms linking nutrient deprivation to nitrate reduction in vegetables remain unclear. Methods In this study, we investigated these mechanisms in lettuce (Lactuca sativa var. ramosa Hort.) by analyzing nitrate content and gene expression in leaves and roots under nutrient deprivation. Results After five days of treatment, nitrate content decreased by 57.49% in leaves and 50.77% in roots. Transcriptome sequencing identified 323 and 3,494 differentially expressed genes (DEGs) in leaves and roots, respectively, with …

Ccaat/Enhancer-Binding Proteins Α And Β Regulate Ovulation And Gene Expression Via Dose- And Stage-Dependent Mechanisms, Hanxue Zhang, Rainer B Lanz, Jimmy Dhillon, Paul D Soloway, Bo Shui, Yi Athena Ren

Faculty, Staff and Students Publications

The preovulatory luteinizing hormone (LH) surge orchestrates complex cellular and molecular events leading to ovulation. CCAAT/enhancer-binding proteins α and β (C/EBPα/β) are transcription factors acutely induced by the LH surge and crucial for ovulation and granulosa cell luteinization. However, biological processes (BPs) and their regulatory mechanisms downstream of C/EBPα/β in the preovulatory ovary are not completely understood. To address this knowledge gap, we generated Cebpa/bfl/fl;Pgr-Cre mutants and compared them with Cebpa/bfl/fl;Cyp19a1-Cre mutant female mice: Cebpa/bfl/fl;Cyp19a1-Cre mutants have undetectable levels of C/EBPα/β throughout the preovulatory stages and do not ovulate, aligning with previous reports; and Cebpa/bfl/fl;Pgr-Cre mutants present gradual depletion of …

Approach To The Patient: From Endocrinopathy To The Diagnosis Of A Histiocytic Disorder, Polyzois Makras, Dana Erickson, Caroline J Davidge-Pitts, Eli L Diamond, Carl E Allen, Kenneth L Mcclain, Jithma P Abeykoon, Ronald S Go, Krishmita Siwakoti, Houman Sotoudeh, Aishwarya Ravindran, Lucinda M Gruber, Gaurav Goyal

Endocrinopathies are frequently the initial presentation of histiocytic neoplasms, which are rare hematologic disorders affecting multiple organ systems. Langerhans cell histiocytosis and Erdheim-Chester disease are 2 such disorders known to infiltrate the hypothalamus and/or pituitary gland, leading to arginine vasopressin deficiency (AVP-D) and anterior pituitary dysfunction (APD) in 20% to 30% of cases, often as the first manifestation. Conversely, histiocytic disorders account for a notable proportion (10-15%) of all pituitary stalk lesions. The diagnosis of histiocytoses is often delayed in such cases due to the nonspecific presentation of endocrinopathies and pituitary involvement. Consequently, endocrinologists are at the frontline and uniquely …

Development And Evaluation Of A Simple Human Body Link Model Considering The Degrees-Of-Freedom Of Shoulders, Mizuki Takeda, Yuki Saito, Kaiji Sato

Progress in Scale Modeling, an International Journal

Modeling of the human body is widely utilized in the field of human–robot interaction, warranting the development of a simple model to measure and recognize the human body movements. To this end, a two-dimensional (2D) human body link model in the sagittal plane has been used to represent the human body with rotating joints and links connecting these joints. The joint positions can be determined by using the coordinates of a limited number of points on the links and estimated using a few sensor outputs when the links are of constant length. However, models with constant link lengths may result …

In The Shadow Of Sovereignty: A Dark Examination Of Hobbes, Sovereign Power, And Genocide, Sidney Dombrovskis

Undergraduate Theses and Capstone Projects

This thesis explores the genocides in Rwanda and Cambodia through the framework of Thomas Hobbes’s political philosophy, focusing on his concepts of the state of nature and absolute sovereignty as articulated in Leviathan. The hypothesis asserts that Hobbes’s state of nature is not merely a hypothetical construct but a tangible reality that can be observed in the actions and failures of authoritarian regimes, such as those of the Hutu government in Rwanda and the Khmer Rouge in Cambodia. These governments, both authoritarian and endowed with seemingly absolute power, paradoxically failed to embody the Leviathan that Hobbes envisioned as the ultimate …

Co-Parenting With The Land In Amazonian Ecuador: Speech, Breath, And Personhood Among The Napo, Runa, Kate R. Nielsen

Anthropology ETDs

This paper explores the processes of personhood in lowland Amazonia and specifically, Kichwa-speaking communities in Ecuador. In lowland Amazonia, personhood is developed through a multitude of social processes in contrast to the Western perception of birth as the defining moment of personhood. As noted in the current literature, an infants' personhood emerges through their relationships with family and community This thesis investigates whether a similar process exists among Kichwa speakers. While Kichwa infants undergo processes akin to their lowland Amazonian neighbors, such as body manipulation and food taboos, shared breath, often through speech, is vital to the ebbs and flows …

How Art Therapy And Emdr Help Asylum Seekers And Refugees Move Towards Healing Trauma: A Literature Review, Anna Mogilevsky

Expressive Therapies Capstone Theses

In the past ten years, there has been a significant rise in the number of asylum seekers and refugee populations worldwide (UNHCR, 2022). Displaced individuals are extremely vulnerable to mental illness because of the compounded trauma experienced in their countries of origin with the stress of immigration, asylum seeking, culture shock, and language barriers. PTSD is affecting 500 million individuals globally, and refugees are especially susceptible to having these symptoms (Farrell, 2020). Art therapy and EMDR are identified as the most promising modalities for treating such trauma.

This literature review examines the various ways EMDR and art therapy have been …

Implementation Of A Nurse Practitioner-Led Video Telehealth Program To Improve Triage For Pediatric Patients In An Ambulatory Intestinal Rehabilitation Center, Elizabeth Castle

Doctor of Nursing Practice Scholarly Projects

Background: Children with short bowel syndrome are medically complex, requiring specialized management and coordinated care to address acute triage issues between scheduled visits. Their risk for rapid decompensation and distance from specialty centers often necessitates telephone-based triage—a typically non-reimbursable method. At a leading Northeastern U.S. children’s hospital, the Intestinal Rehabilitation (IR) center manages high-risk telephone triage of these patients’ concerns using experienced nurse practitioners. The inability to directly visualize patients during telephone encounters, however, limits clinical assessment and decision-making, presenting challenges to efficient and safe care delivery. A systematic literature review indicated that telehealth can enhance parental confidence, improve clinician …

Seeing Through The Incense Smoke: Understanding The Meanings Of Ancestral Rites In Vietnam For The Sake Of A Pastoral Approach In Christian Mission, J.P. Cima

Doctor of Philosophy Dissertation

Cima, J.P. “Seeing Through the Incense Smoke: Understanding the Meanings of Ancestral Rites in Vietnam for the Sake of a Pastoral Approach in Christian Mission.” Ph.D. diss., Concordia Seminary, 2025. 285 pp.

The veneration of ancestors at family altars has long been a defining feature of everyday Vietnamese life that poses a critical missiological problem for Christian mission in Vietnam. May Christians participate in ancestral veneration rituals? Current and historical responses to this question, among Protestants and Catholics alike, have not been uniform. Moreover, many responses have been based on assumed or oversimplified understandings of the rites’ meaning which recent …

Changing The Narrative: A Meta-Analysis Of Narrative Therapy And It's Changes Since Inception, Elijah J. Shriner

Honors Projects

This meta-analysis examines the effectiveness of narrative therapy across 43 studies involving diverse populations and mental health conditions. Studies included randomized controlled trials, quasi-experimental designs, and case studies, with outcome measures primarily focused on depressive symptoms, interpersonal functioning, and psychological distress. Effect sizes were calculated using Hedges’ g to account for small sample bias. Overall, narrative therapy demonstrated moderate to large positive effects on symptom reduction and client well-being, though variability in study design and reporting limited the precision of some estimates. Findings support narrative therapy as a promising intervention across clinical contexts, while highlighting the need for more rigorous, …

Quest For Purpose In Education: An Autoethnographic Study Of A Chinese Student’S Cross- Cultural Journey Through Logotherapy And Culturally Relevant Leadership, Bingsheng Chen

Teacher Education, Educational Leadership & Policy ETDs

This autoethnography examines a Chinese student's search for meaning while transitioning between Chinese and U.S. academic systems, shaped by the interplay of cultural values, societal pressures, and personal agency. Guided by Viktor Frankl’s logotherapy and Culturally Relevant Leadership (CRL), the study uses reflexive narrative analysis to explore how this personal quest for purpose intersected with institutional structures and cultural contexts (e.g., St. John's College, University of New Mexico). Illuminating profound challenges—including cultural shock, systemic inequities, and the emotional toll of adaptation—the research reveals a transformative journey of navigating dissonance, reframing adversity, embracing a dual cultural identity, and ultimately finding meaning …

Leading Through Crisis: San Diego County Schools' Response To The Social Emotional Needs Of All Students, Johana Bielma

Dissertations

The COVID-19 pandemic led to unprecedented school closures, forcing administrators to take decisive action to radically change the educational system. The imperative to switch to remote learning transformed the dynamics of teaching and learning, leading to both immediate and long-term academic and social emotional consequences for all stakeholders. When schools reopened, administrators faced the challenge of reintegrating students into in-person learning while addressing the pandemic’s lasting effects on academics, mental health, and school safety. While academic regression was evident, the extent of students’ emotional struggles was less anticipated. Many students exhibited increased irritability and mental health issues such as depression …

Chains Of Equity: How Nationwide Injunctions Are Unconstitutional, Irfan Mohamed

Themis: Research Journal of Justice Studies and Forensic Science

Since the early judicial beginnings in the English Courts of Chancery, the principles of equity have guided judicial remedies for centuries. Modern American courts inherited these principles through reception statutes passed by newly independent states, which adopted English common law, including the concept of equity as a means of providing narrowly tailored remedies to resolve specific injuries. This paper examines the historical foundations of equity and argues that nationwide injunctions, which extend beyond the immediate litigants to affect the general public, are inconsistent with these principles and, therefore, unconstitutional. A historical and doctrinal analysis of the English Court of Chancery, …

Evaluating The Effectiveness Of Chatgpt In Solving Math Problems Across Varying Levels Of Difficulty And Its Implications On Education, Emma Nicol

Undergraduate Theses and Capstone Projects

This project aims to make the literature on LLMs, like ChatGPT, more accessible, while also evaluating its effectiveness in solving math problems of varying difficulty. In order to achieve this, I generated and ranked math problems based on their difficulty and the analysis/steps required to complete them correctly. From there, these problems were inputted into ChatGPT to be solved, and patterns of error were documented in order to see what steps or sections of these problems were conducted incorrectly. Additionally, analysis of this information allowed me to determine the benefits of ChatGPT and what areas still need improvement, in terms …

Everyday Nonverbal Communication: A Comparative Study Of South And East Asian And The Mid-Atlantic United States Cultures, Jamila Jones

How We Show Up Matters: Transformative Adult Social Emotional Learning To Build Equity-Centered Schools, Samantha L. Rummage-Massey

Dissertations

Transformative Social Emotional Learning (tSEL) expands traditional SEL by integrating equity and social justice to cultivate student development and as a framework for educator growth and systemic change in education (Jagers et al., 2019). Unlike traditional SEL, which primarily targets students, tSEL emphasizes educators’ role in disrupting inequitable practices, making it a powerful tool for reimagining schools as justice-oriented spaces. This qualitative case study explores how tSEL professional development influences educators’ sense of identity, agency, and belonging, along with their reflections on systemic inequities and application of Critical Pedagogy (Freire, 1970) in personal and professional contexts. Data collection included semi-structured …

Understanding And Engaging In Equity Work: A Phenomenological Action Research Study Of Community College Esol Instructors, Emily E. Packer

Dissertations

Community colleges (CCs) are regarded as accessible and affordable pathways to higher education and financial mobility, offering significant potential to promote educational equity (Fink et al., 2023). These institutions enroll the largest number of English for Speakers of Other Languages (ESOL) students in adult education; however, CC ESOL students face lower rates of degree completion and transfer compared to their non-ESOL peers (David & Kanno, 2021; Fink et al., 2023; Raufman et al., 2019). While research has examined factors contributing to low CC ESOL student persistence and interventions to improve overall CC student outcomes, research on specific efforts to support …

Culturally Affirming Independent School Board Governance: Centering The Experiences Of Independent School Board Members Of Color, Christopher S. Dennis Phd

Dissertations

As schools become more diverse, K–12 independent school boards benefit from diversity (Jernigan et al., 2010; Tolbert Smith, 2022). This study examined the narratives of independent school board members of color (BMOC) across the United States’ racialized history of education (Anderson, 1988; Omi & Winant, 2014). The study used a survey (n = 23) and interviews (n = 9) based on Helms’s (1996) racial identity theory and Booth-Bell et al.’s (2021) board governance theory. This multiple case study examined survey responses of BMOC from 17 schools governed by the National Association of Independent Schools (NAIS). Nine respondents were …

Exploring A Holistic Conceptualization Of Destructive Leadership: Perspectives From The Lived Experiences Of Latino Law Enforcement Command Staff Officers, Carmelin Rivera

Dissertations

Recently, there has been an increased interest in destructive leadership or what is characterized as the dark side of leadership. There is, in fact, no consensus in the literature about the definition of destructive leadership, and this murkiness has led to two somewhat different approaches to understanding this phenomenon: 1) a leader-centric approach that emphasizes the bad behaviors and traits of so-called toxic leaders and 2) a much broader, holistic approach, often discussed as the toxic triangle (Padilla et al., 2007), that focuses on how destructive leadership is co-created by a toxic system of bad leaders and susceptible followers …

Liberatory Love: Exploring Educators’ Perspectives In Alternative Education, Kamala J. Mallipudi

Dissertations

Establishing an operational understanding of love is difficult. The struggle is magnified when attempting to create a shared vision of love across a group of educators. As Freire (1970/2005) and Darder (2011) affirmed, academic success is advanced when educators demonstrate love as part of their praxis. Continuation high schools represent a population of at-promise students who stand to gain much when their educators employ liberatory love practices. This study examined how educators’ perceptions about liberatory love are shifted or formed when they read, discuss, and reflect on the topic with their colleagues. This study drew on critical pedagogy and engaged …

Latinas In Higher Education: Paving & Weaving Wholeheartedly, Ariela M. Canizal

Dissertations

The deficit model in research has often framed Latinas in higher education through a lens of barriers and challenges, reinforcing stereotypes that depict them as unlikely to succeed in academic spaces. However, Latinas are actively resisting these narratives, weaving their resilience into their stories as they navigate the complexities of higher education, culture, and identity. This study examines how Latina students incorporate cultural background, familial support, and personal agency to thrive academically while challenging systemic obstacles and societal expectations. The research question that guided this study is: In what ways do undergraduate Latina students navigate identity as they experience leadership …

Post Racial Reckoning: Montessori Instructors' Perspectives On Teaching Through An Antibias Antiracist Lens, Jasmine E. Williams

Dissertations

Prior to the racial reckoning of 2020, Montessori teacher education programs (MTEPs) have only narrowly focused on social justice education (Aronson et al., 2020; Bartolomè, 2004; Cook, 2015; Cross, 2005; D’Cruz, 2022; King, 1991). Although MTEPs began to respond differently post-reckoning, support for implementing practices like antibias antiracist (ABAR) instruction was often absent. This study sought to understand how the racial reckoning and efforts to include an ABAR lens impacted the teaching practices of instructors in MTEPs. While ABAR-related studies exist in general teacher education (Blanchard et al., 2018; Madkins & Nazar, 2022; Martinez-Alba, Herrera, & Hersi, 2022), few focus …

Advancing Equity In Financial Aid For Black Students: A Document Analysis Study Of Student Equity Plans In California Community Colleges, Edwina Williams

Dissertations

This study examined how California Community Colleges (CCCs) constructed financial aid discourse in Student Equity Plans (SEPs) and assessed whether these strategies mitigated or perpetuated racial disparities for Black students. Previous scholarship identified racial inequities in financial aid systems and explored how equity planning documents addressed race; yet, the influence of institutional discourse on financial aid access remained underexamined. This study contributed to the literature by applying critical race hermeneutics (CRH) to examine how SEPs outlined financial aid strategies, with particular attention to the framing of work–study opportunities and the extent to which the SEP intended to employ race-conscious approaches. …

Challenging Dominant Mindset Ideologies: Transforming Teaching And Learning That Impact Latinx Students, Francisco Lopez

Dissertations

Teacher identity poses a central connection to social justice education as researchers call for studies to pay attention to the cultural identities of those teaching in our schools when practices like color blindness are a common practice amongst teachers that keeps racial and social power intact. Despite the overwhelming presence of White teachers nationwide, we must pay attention to the specific needs of Teachers of Color in our classrooms. The assumption is often made that teachers of Color already have the knowledge on how to enact culturally responsive pedagogy. This study investigates the relationship between Critical Race Theory (CRT) and …

Becoming A Beloved Community: A Restorative Reckoning For A Radical Conversion To Transform Discourse In Higher Education, Latasha Tomay Varlack-Butler

Dissertations

This dissertation critically examines the misappropriation of Restorative Justice Discourse (RJD) within three predominantly white institutions (PWIs), analyzing 59 institutional documents through Critical Discourse Analysis, Relational Critical Discourse Analysis, and Rhetorical Criticism (Fairclough, 1995; Vaandering, 2021; van Dijk, 2008). Tribal Colleges and Universities and South African institutions have emerged as exemplars of authentic RJD, countering co-optation within PWIs. The findings demonstrate that RJD as applied in PWIs is framed in ways that attenuate its transformative potential, perpetuating color-evasiveness (Bonilla-Silva, 2017) and obscuring the intersectional experiences of Black, Indigenous, and disabled communities (Crenshaw, 1991; Million, 2009).

Grounded in decolonial praxis (Smith, …
