The Unexpected Influence Of Legacy Conspecific Density Dependence, Lukas J. Magee, Joseph A. Lamanna, Amy T. Wolf, Robert W. Howe, Yuanming Lu, Denis Valle, Daniel J. B. Smith, Robert Bagchi, David Bauman, Daniel J. Johnson

Biological Sciences Faculty Research and Publications

When plants die, neighbours escape competition. Living conspecifics could disproportionately benefit because they are freed from negative intraspecific processes; however, if the negative effects of past conspecific neighbours persist, other species might be advantaged, and diversity might be maintained through legacy effects. We examined legacy effects in a mapped forest by modelling the survival of 37,212 trees of 23 species using four neighbourhood properties: living conspecific, living heterospecific, legacy conspecific (dead conspecifics) and legacy heterospecific densities. Legacy conspecific effects proved nearly four times stronger than living conspecific effects; changes in annual survival associated with legacy conspecific density were 1.5% greater …

Modeling Blue Mondays: A Preclinical Evaluation Of 3,4-Methylenedioxymethamphetamine Binge Dosing On Responding Maintained By A Progressive Ratio Schedule Of Food Reinforcement In Male Sprague-Dawley Rats, Candace Brenda Johnson

Dissertations

3,4-Methylenedioxymethamphetamine (MDMA) has been abused recreationally in the rave scene for decades. As pharmacotherapy research has progressed to develop alternative medications to treat trauma-related psychiatric symptoms, MDMA has become a prime candidate for medication-assisted psychotherapy in the treatment of PTSD and will soon be FDA approved for medicinal use. Despite convincing evidence for favorable clinical outcomes, this substance has been known to contribute to acute depressive states following excessive use. The sharp decrease in mood and cognitive impairment following MDMA use is colloquially termed Blue Mondays. Measuring lack of motivation or more broadly anhedonia through withdrawal of acute and chronic …

Esg Factors In Municipal Securities Disclosures: Toward A Materiality Concept, Justin Marlowe

Northern Illinois University Law Review

State and local governments in the United States finance most of their infrastructure investment with debt instruments known as municipal bonds. The federal government does not directly regulate when or how municipal issuers access the municipal bond market, and only indirectly regulates the content of municipal borrowers’ disclosure to investors. A consequence of that unique regulatory structure is that municipal borrowers have wide discretion on whether to disclose falling property values, rising crime rates, and other long-term threats to their ability to repay investors. This is at odds with the ever-expanding information needs of investors who seek to align their …

Snpaimer: R Package For Evaluating Ancestry Informative Marker Contributions In Non-Model Population Diagnostics, Kim L. Vertacnik, Oksana V. Vernygora, Julian R. Dupuis

Entomology Faculty Publications

Motivation: Single nucleotide polymorphism (SNP) markers are increasingly popular for population genomics and inferring ancestry for individuals of unknown origin.

E6 Inhibtion-Mediated Combinatorial Therapy For Hpv+ Hnscc, Sonia Whang

Loma Linda University Electronic Theses, Dissertations & Projects

High-risk human papillomaviruses (HPV) are the causative agents of virtually all cases of cervical cancer and up to 80% of head and neck squamous cell carcinoma (HNSCC). Current treatment options include chemo- and radiotherapy, though the effectiveness of these therapies is limited by the viral oncoprotein E6, which disrupts apoptotic pathways by binding to and accelerating the degradation of molecules such as p53 and caspase- 8. Our hypothesis was that inhibiting E6 and rescuing the apoptotic mediators would increase the effectiveness of apoptotic agents. The aims of this study were to first, develop an HPV+ HNSCC xenograft model to test …

A Drug's Life: The Untapped Potential Of Secondary Pharmacology Studies In Drug Development, Christina Scott

The University of New Hampshire Law Review

The United States Food and Drug Administration has evolved over the past century to regulate new medicine and protect the public from harmful or ineffective drugs. Drug development and testing science have advanced rapidly alongside the FDA’s increased regulation, enabling pharmaceutical companies to assess a drug's potential adverse reactions by studying its reactivity with various proteins called "off-target receptors." Off-target proteins are often screened and reported in the Investigational New Drug Application as a percentage indicating the drug's binding strength to each protein, which suggests the strength of a particular adverse drug effect. Adverse drug effects often lead to unfavorable …

Building Partnerships With Indigenous Communities, Andrea Plamondon

Dissertations

Non-indigenous researchers embark on research with indigenous communities with good intentions but can unintentionally continue to oppress. While existing research shows building partnerships with indigenous communities, requires researchers to work “with” not “for” communities and walk side-by-side, and to do so with reciprocity, respect, relevance, responsibility and reverence, this research study identified an iterative model to learn, follow, and emerge research relationships through ongoing connections and outlined the mindsets to consider and assess often. Ten non-indigenous researchers from the US and Canada shared their stories about building relationships with indigenous communities. Through their stories of successes and challenges, strengths and …

Addressing The Importance Of Recruitment And Retention Of Black And Latinx Teachers: Strategies Designed To Diversify The Teacher Pipeline, Shavon Pittman

Dissertations

The United States student demographic has shifted significantly, with minorities, particularly Black and Latinx students, now constituting almost half. However, the diversity of the teaching profession, historically led by White females, lags behind, with Black and Latinx teachers comprising less than 30%. This lack of representation poses challenges for students without culturally similar educators. My research explores the impact of teacher diversity on Black and Latinx students' success, revealing positive outcomes. Yet, attracting and retaining minority teachers faces obstacles, including feelings of isolation and financial concerns. Recommendations include educational pathways, scholarships, mentoring programs, salary incentives, and professional learning communities to …

Dissertations

Without academic resources and accommodations, neurodivergent students with mild to moderate Learning Disabilities (LD) may be unable to navigate the academic challenges and rigor associated with college success. I used a mixed-methods research design to collect data from various stakeholders to determine the supports neurodivergent students with LD need to be successful in college. My findings indicated students need accommodations for their learning differences, access to assistive technology, access to counseling or mental health services, and access to specialized support personnel to be successful. I recommended a policy to ensure neurodivergent students and their caregivers are aware of post-secondary institutions …

Consciousness And Physicalism, Brian Mcgowan

Dissertations, Theses, and Capstone Projects

Physicalism is a philosophy of mind which attempts to explain consciousness as resulting from physical causes. The lack of a complete and consistent mathematical theory to explain physical causation has led other philosophers of mind to propose that consciousness is a nonphysical essence, property, or substance. However, the idea that physics can be defined atomically and/or deterministically leads to explanatory problems for consciousness, as well as for the dualisms which explain consciousness under these assumptions. This thesis advances a position called “continuous physicalism” which takes all material to result from deformations in the physical medium of space, and any changes …

Toward Otherworlding The Teaching-Learning Of Psychology With Community College Students, Francisco Medina

Dissertations, Theses, and Capstone Projects

This dissertation reimagines a different relationality to teaching-learning psychology in the community college classroom through a series of three separate articles. Each article draws on quasi-ethnographic, autoethnographic, and group discussions elements to wonder about the types of theoretical, methodological, and pedagogical dimensions that might make psychology courses more attuned and accountable to younger generations and the end of the world as we know it. The first article explores the metaphysical inseparability, interdependence, and co-constitution of teaching-learning, theory-making, and collective world-making in the psychology community college classroom as an invitation to the end of psychology as we know it. I argue …

Language Play And Racial Dysphemism In The Marrakchi Language Space, Spencer Fausel

Dissertations, Theses, and Capstone Projects

This study seeks to divulge the meaning and popular usage of two phonetically similar yet reportedly distinct dysphemisms spoken and understood in the Marrakchi dialect of Moroccan Arabic (Darija). Darija speakers across the North African lingua-space use the term "qlawi" to denote testicles. In Morocco, speakers utter "qlawi" to express negation or pejorative notions of being, the term commonly wielded to disparage or vituperate a frustrating person or object—drawing connections to the subaltern, the lowly, the destitute, the stupid, the possessionless, and potentially to the racialized (non)object. The word itself can stand as a syntactic substitute for “nothing” in certain …

Desire Lines: An Annotated Screenplay, Alexandra Tydings

Dissertations, Theses, and Capstone Projects

This thesis explores under theorized questions of power, sexuality, and gender on the film set by analyzing the role of the Intimacy Coordinator (IC), a recent arrival in that space. A film set has its own culture, built from conventions, rituals, and hierarchies. The work of the IC occurs at the nexus of some of the most entrenched and invisible of these dynamics, including gender roles, bodily autonomy, and the power to consent. The author, having worked professionally as an actress, a director, and most recently an Intimacy Coordinator in film and television, now turns to feminist and queer theory, …

When Critics Are Artists: Ekphrasis In Erotic Art Criticism, Joanna A. Ligon

Dissertations, Theses, and Capstone Projects

In “Against Interpretation,” Susan Sontag argues for an erotics of art in art criticism in place of hermeneutics. In this thesis, I examine erotics of art, a focus on form and experiencing art instead of exclusively on content, in practice. Drawing on other essays by Sontag, specifically the essay “Godard” in comparison with the filmmaker Jean-Luc Godard’s own filmic criticism in Breathless, criticism according to an erotics of art becomes a new artwork itself. Subsequently, I present a definition of erotic through Anne Carson and Roland Barthes and juxtapose the term with Hans-Georg Gadamer’s hermeneutics. The comparison ultimately undoes …

From “Total Destruction” To “Total Dictatorship”: The Influence Of Ernst Jünger’S Visionary Fascism, Nick Schiff

Dissertations, Theses, and Capstone Projects

This paper seeks to answer one central question: How can the life and work of Ernst Jünger help illuminate the development of fascist ideas, culture, politics, and power across Europe from 1920-1945? The components of that question are: what were the core elements of Jünger’s aesthetics, morality, and politics? How did he synthesize these elements to create his influential vision of German fascism? What were Jünger’s interactions and exchanges with other European fascists, as well as influential Nazis including Carl Schmitt, Joseph Goebbels, and Adolph Hitler himself? How did Jünger’s new Fascist politics and aesthetics affect them? I argue that …

Recognizing Elder Abuse In Mongolia: Experiences Of Family Physicians, Ariunsanaa Bagaajav

Dissertations, Theses, and Capstone Projects

Elder abuse is a globally recognized social problem with serious consequences. The most recent meta-analysis estimates the prevalence of elder abuse at 17%. Studies conducted in Asian countries suggest prevalence rates higher than the global average. Social stressors including alcoholism, unemployment, and poverty related to economic transitions, many of which apply in Mongolia, are associated with elder abuse. International studies have found that health care providers play critical roles in detecting cases of elder abuse. Due to universal access to primary care in Mongolia, family physicians are uniquely positioned to interact with potential victims of elder abuse. However, the extent …

Chipping The Blue Wall: The Effect Of Dogs On Police Officer Receptivity To An Employee Assistance Program, Kenneth M. Quick

Dissertations, Theses, and Capstone Projects

There is substantial evidence that demonstrates the negative impact of stress on police officer mental health is increasing due in large part to perceived societal shifts in support for the police and trends in criminal justice reform efforts. While employee assistance programs (EAP) are the dominant mechanism for police agencies to address officer mental health, officers are reluctant to use them due to a combination of mental health stigma and organizational distrust. This dissertation studied police officer perceptions of an employee assistance program (EAP) and the effect of exposure to professionally trained dogs during an outreach session on indicators of …

Extractivism And The Defense Of Life And Territories: An Account Of Latin American Environmental Thought, Pedro Monque

Dissertations, Theses, and Capstone Projects

We are living today through an environmental crisis of planetary proportions. Recent decades have seen the proliferation of distinct environmentalisms around the world. In Latin America, a unique environmental vocabulary is being born out of resistance to northern framings of the environmental crisis whose proposed solutions often deepen environmental injustice vis-à-vis the global south.In this dissertation, I provide an account of the key themes in this lively but undertheorized tradition that I call Latin American environmental thought.

The conceptual core of Latin American environmental thought, I argue, are the concepts of extractivism, the defense of life and territories, and alternatives. …
