A Tale Of Three Resources: The Influence Of Multiple Resources On Plant-Herbivore Interactions, Neha Mohan Babu

Dissertations - ALL

Although studies indicate that plant growth can be co-limited by multiple resources, particularly water, nitrogen (N), and phosphorus (P), the role of co-limiting resources in driving plant-herbivore interactions remains poorly understood. Evidence indicates that the resources that limit plant and herbivore growth may differ which likely influences trophic interactions. In this dissertation, I explored how multiple resource limitation of plants affects herbivore abundance, herbivore impact on plant biomass, and plant traits, using both theoretical and empirical methods. As none of the existing hypotheses account for the effects of multiple resource limitation, I developed a novel theoretical model to predict the …

The Poverty Of Simplicity: Austerity, Alienation, And Tiny Houses, Brian Richard Hennigan

Dissertations - ALL

Tiny houses – stand-alone, fully functional dwellings generally between 100 and 400 square-feet – are increasingly popular in the United States. The degradation of working class life wrought through neoliberal policy and then punctuated by the Great Recession propels this popularity. Next to traditional houses, tiny houses are significantly cheaper. Those among the middle stratum of the working class have sought out tiny houses as a means to ease their financial anxiety. Rather than merely a newer form of cheaper housing, an entire lifestyle movement has emerged around tiny houses. Anti-consumerism is the keystone to this lifestyle movement. For enthusiasts, …

Policy And Polity: Space, Boundaries, And Governance In Early Modern London, 1580-1640, Michael Britton

Dissertations - ALL

The kingdom's principal city for law, governance, trade, and consumption, early modern London experienced a period of rapid growth and sprawl from the mid-sixteenth century. This nurtured more dense and frequent mobility and produced a dynamic, kinetic city. For civic authorities, however, boundaries took on greater urgence. Drawing on theories and principles of border studies, this dissertation treats the city's boundaries as processes forged and transformed by engagement, by the interplay between popular activity, political programs, and perceptions of space and authority. Policy and Polity, Space, Boundaries, and Governance in Early Modern London, 1580-1640 examines bordering at London Bridge, the …

Not Appropriate For Children: A Look At The Composition Practices And Rhetorical Strategies Of Single Moms In Academia, Alexandria Margethe Hanson

Dissertations - ALL

This dissertation explores how single mothers in higher education across geographic locations, academic ranks, disciplines, and identities build support systems and draw on rhetorical strategies derived from their embodied knowledge to survive and navigate in academia. Single mother experiences are underrepresented in scholarship about parenting in higher education. This absence is evidenced in policies, systems, and structures that prioritize the needs of heteronormative family units. The lived experiences and material realities of single mothers reveal how their lives outside academia shape and are shaped by their lives within it, including scholarly activity, interactions with colleagues, and relationships with their children. …

Dissertations - ALL

Background: The clinical perfusionist is a member of the open-heart-surgery team and responsible for operating the life support equipment that replaces the function of the patient's heart and lungs and arrests and restarts the patient's heart in the course of a Cardiopulmonary Bypass (CPB) procedure. In the perfusionists scope of practice, the consequence of unskilled actions, inaccurate understanding or delayed decision making may result in significant patient morbidity or even death. Historically, perfusion students have learned and practiced their skills within a clinical preceptorship program in which an experienced clinician allows the novice student to operate the life support equipment …

Antimicrobial Susceptibility Of P. Aeruginosa Clinical Isolates, Tian Gao

Theses - ALL

Long-term infection caused by P. aeruginosa poses a major threat to personal and public health, and causes billions of dollars in medical expenses. To develop more effective controls, it is important to accurately evaluate antibiotic susceptibility of clinical isolates and understand how susceptibility changes during the course of infection. Conventional drug susceptibility tests using nutrient-rich media have been questioned regarding their relevance due to the difference between the model in vivo test conditions and the environment in the patients. Here, we report that 27 clinical strains of P. aeruginosa isolated from cystic fibrosis patients showed higher drug resistance in Artificial …

A Pilot Study Exploring The Relationship Between Urban Greenspace Accessibility And Mental Health Prevalence In The City Of San Diego In The Context Of Socioeconomic And Demographic Factors, Alexis Wilderman, Marcus Lam, Zhi-Yong Yin

Environmental and Ocean Sciences: Faculty Scholarship

The connection between urban greenspace and mental health is a robust but unsettled area of research in the public health and urban planning literatures. Inconsistent findings in prior studies are mostly due to differences in greenspace measurements and interrelations with socio-demographic factors. This study examines the relationships of mental health prevalence (MHP) with health prevention, socioeconomic and race-ethnicity factors, and proximity to greenspace at the census-tract level in the City of San Diego, California, using data from the CDC 500 Cities Project and US Census Bureau. We considered three greenspace proximity measures: distances to specified vegetation types, parks, and tree …

Proactive Public Libraries For Community Resilience And Ecological Sustainability, Alex Crowley

Student Theses

Public libraries are key institutions for dealing with crises in communities. In the midst of a devastating global pandemic and a continual wave of social uprisings, it is necessary for library workers to more seriously reckon with the need for drastic changes in the ways that public libraries respond to and operate within these conditions. It is unclear to what extent libraries have adopted significant changes recommended by organizations and professionals in the field to become resilient and ecologically sustainable. These changes include the abandonment of neutrality discourse, a democratic restructuring of workplaces, and the relocalization of library programs and …

Improved Bathymetry Leads To >4000 New Seamount Predictions In The Global Ocean – But Beware Of Phantom Seamounts!, C Yesson, Tb Letessier, A Nimmo-Smith, P Hosegood, As Brierley, M Hardouin, R Proud

School of Biological and Marine Sciences

Seamounts are important marine habitats that are hotspots of species diversity. Relatively shallow peaks, increased productivity and offshore locations make seamounts vulnerable to human impact and difficult to protect. Present estimates of seamount numbers vary from anywhere between 10,000 to more than 60,000. Seamount locations can be estimated by extracting large, cone-like features from bathymetry grids (based on criteria of size and shape). These predicted seamounts are a useful reference for marine researchers and can help direct exploratory surveys. However, these predictions are dependent on the quality of the surveys underpinning the bathymetry. Historically, quality has been patchy, but is …

Bactericidal Effects And Stability Of Ll-37 And Cama In The Presence Of Human Lung Epithelial Cells, Regina Geitani, Carole Ayoub Moubareck, Floriane Costes, Léa Marti, Gabrielle Dupuis, Dolla Karam Sarkis, Lhousseine Touqui

All Works

Cationic antimicrobial peptides (CAMPs) are important actors in host innate immunity and represent a promising alternative to combat antibiotic resistance. Here, the bactericidal activity of two CAMPs (LL-37, and CAMA) was evaluated against Pseudomonas aeruginosa (PA) in the presence of IB3-1 cells, a cell line derived from patients with cystic fibrosis. The two CAMPs exerted different effects on PA survival depending on the timing of their administration. We observed a greater bactericidal effect when IB3-1 cells were pretreated with sub-minimum bactericidal concentrations (Sub-MBCs) of the CAMPs prior to infection. These findings suggest that CAMPs induce the production of factors by …

Sexual Dysfunction In Schizophrenia: A Narrative Review Of The Mechanisms And Clinical Considerations, Amber N. Edinoff, Catherine A. Nix, Juliana M. Fort, Jeanna Kimble, Ryan Guedry, George Thomas, Elyse M. Cornett, Adam Kaye, Alan D. Kaye

Pacific Faculty Work

Psychiatric disorders, in general, have a high prevalence of sexual problems, whether from the psychopathology of the disorder itself, pre-existing or co-morbid sexual disorder or from side effects of the treatment for mental disorders. Many patients report an already existing sexual dysfunction at the onset of diagnosis. The risk association for developing sexual dysfunction in patients with schizophrenia includes antipsychotic use and resulting hyperprolactinemia, age, gender, and disease severity. Medication side effects lead to nonadherence, and relapses lead to structural changes in the brain, treatment resistance, and worsening of symptoms. Findings in certain studies propose serum prolactin and thyroid-stimulating hormone …

Protecting The University As A Physical Place In The Age Of Postdigitization, Ryan M. Allen, Peter Mclaren

Education Faculty Articles and Research

Covid-19 forced higher education sectors across the world to digitize the entire university experience online. There are now calls for universities to continue chasing continued and further digitization, often from for-profit businesses and those in Silicon Valley who have been promising to disrupt the sector for decades. We argue that the pandemic has illustrated how crucial universities are to their local communities, and efforts should be made to emphasize their physical place and space. The destruction of American cities in favor of auto-centric suburbs provides a parallel for the possible future of higher education. The Cult of Efficiency mindset and …

First-Generation College Student Baccalaureate Attainment: Investigation Of A Psychological Model Of College Student Retention, Timothy Wasserman

Dissertations - ALL

This dissertation examined predictors of retention and graduation for first-generation (FG), first-year students at a selective, private, residential university in the northeastern United States. The theoretical framework was Bean and Eaton's (2000, 2001/2002) Psychological Model of College Student Retention. The purpose of the study was to test the Bean and Eaton model and ascertain how students' entry characteristics, experiences, psychological outcomes, attitudes, and intent to return impacted retention and graduation outcomes. Previous research shows that FG students face challenges in persisting (Cataldi et al., 2018; Choy, 2001; Ishitani, 2016); yet it is through graduating from a prestigious four-year institution that …

A Solid-State Phase Camera For Advanced Gravitational Wave Detectors, Erik Muniz

Dissertations - ALL

I present a novel way of wavefront sensing using a commercially available, continuouswavetime-of- ight camera with QVGA-resolution. This CMOS phase camera is capable of sensing externally modulated light sources with frequencies up to 100 MHz. The high-spatial-resolution of the sensor, combined with our integrated control electronics, allows the camera to image power modulation index as low as -62 dBc/second/pixel. The phase camera is applicable to problems where alignment and mode-mismatch sensing is needed and suited for diagnostic and control applications in gravitationalwave detectors. Specically, I explore the use of the phase camera in sensing the beat signals due to thermal …

The Effects Of Cannabidiol And Analgesic Expectancies On Experimental Pain Reactivity In Healthy Adults: A Balanced Placebo Design Trial, Martin De Vita

Dissertations - ALL

Experimental pain trials have been unable to determine whether cannabinoid analgesia is attributable to intoxication, analgesic expectancies, and/or pharmacological action. One approach to resolving this issue involves testing the effects of analgesic expectancies and cannabidiol (CBD), a non-psychoactive cannabinoid, on human pain reactivity using a balanced placebo design. Despite its frequent use for pain relief, no experimental research has tested the analgesic effects of CBD in humans. Using a within-subjects 2 x 2 balanced placebo factorial design, we experimentally tested the effects of CBD and expectancies for receiving CBD on pain reactivity (i.e., pain threshold, tolerance, intensity, unpleasantness, conditioned pain …

"We, As Parents, Do Have A Voice": Learning From Community-Based Programs Effectively Engaging Parents In Urban Communities, Elizabeth Gil, Ashley Johnson

GSE Faculty Publications

Utilizing Yosso’s community cultural wealth framework as a theoretical lens, we sought to examine how nontraditional, community-based family engagement programs impacted adult family members’ thoughts and actions about engagement with their children's schools. The study drew primarily from the interviews, observations, and document analysis of two nontraditional family engagement programs in urban communities. Findings indicate that program approaches built upon and extended families’ social and navigational capitals. Educational leaders can more meaningfully engage urban families by learning from and incorporating practices implemented by the programs we examine and discuss in this article.

Developing An Air Pollutant Emissions Database For Global Economic Analysis, Maksym Chepeliev

Department of Agricultural Economics Faculty Publications

According to the Global Burden of Disease study (Cohen et al., 2017), in 2015 ambient air pollutant emissions caused 4.2 million deaths and a loss of 103.1 million disability-adjusted life-years, making it the fifth-ranked global risk factor. In terms of the welfare costs of mortality and illnesses associated with outdoor air pollutant emissions, global estimates for 2015 range between $2.7-3.2 trillion (Coady et al., 2015; OECD, 2016). Still, while greenhouse gas emissions are usually well represented in many global economic databases and models, air pollutant emission accounts in most cases are not included. In particular, this is the case for …

Positive Leadership Theory For Online Dissertation Mentoring, Lee Stadtlander

Journal of Educational Research and Practice

A number of theoretical models have been suggested for how to mentor doctoral students. However, they tend to rely on hierarchical and authoritarian relationships between the faculty and students. Such models tend to create dependency and fear of the faculty, resulting in a reluctance in coming to the mentor for guidance. Such models do not tend to work well with online adult doctoral students with jobs and families. This paper proposes a model of positive leadership for online doctoral mentors, where mentors are accessible and create an environment where success is assumed and social support is provided by both the …

Review Of: Kleinsasser, Ian. 2019. Blessings And Burdens: 100 Years Of Hutterites In Manitoba., Martin Lutz

Journal of Amish and Plain Anabaptist Studies

Ian Kleinsasser’s short book on Hutterites in Manitoba deserves attention. It is based on three lectures given at the inaugural Jacob D. Maendel Lectures in 2019. This lecture series was established in honor of Jacob Maendel (1911-1972) in the context of the centennial preparation of permanent Hutterite settlement in Canada. The three lectures were held in Portage la Prairie, and as the book’s introduction points out, were attended by representatives of both Schmiedeleut I and II groups. Jacob D. Maendel was a prominent Schmiedeleut leader of his generation and a driving force in advancing Hutterite education. His initiative led to …

Agricultural Support For The Old Colony Mennonites Of Belize: A Collaborative Effort Between North American Old Order Mennonites And A Cornell Extension Educator, Judson Reid

Journal of Amish and Plain Anabaptist Studies

The Old Colony Mennonites of Belize practice a conservative form of Anabaptism where technology, dress and lifestyle choices are informed by church standards. Members live in a spatially contiguous Colony, which creates land pressure over time as population increases. The development of new Colonies is necessary for the Mennonites to participate in agricultural livelihoods. The Indian Creek Colony of Belize has experienced agricultural and economic hardships since its inception in the 1989 due to land costs, crop failures and debt structure. Old Order Mennonites of North America developed an outreach effort to assist with on-farm production of vegetable crops to …
