Studies Of Damage Tolerance In Automated Fiber Placement Based Heterogeneous Meso-Architectured Carbon/ Epoxy Composite Laminates., Karan Kodagali

Theses and Dissertations

Traditional unidirectional (UD) carbon fiber-reinforced polymer matrix composites manufactured via automated fiber placement (AFP) are widely used in aerospace structures. While heterogeneous at the micro-scale, these materials are homogeneous at the meso-scale (ply-scale). The major limitation is its limited toughness, poor damage tolerance/impact resistance capability and the inability to sufficiently redistribute stresses, resulting in strength-toughness tradeoffs, making them susceptible to impact damage. From previous studies, there is an understanding that fiber architecture has a first order effect on the damage tolerance. Introducing new discontinuous/heterogeneous meso-scale architectures, through an optimal merger of material and structure, can result in unprecedented property improvements …

Quantification Of The Internalization Of A Commercially Available Silver Nanoparticle To The Bacterium Escherichia Coli, Samantha Mcneal Case

Theses and Dissertations

Nanoparticles (NPs), materials with dimensions ranging from 1 to 100 nanometers, are widely used in various consumer products, with silver nanoparticles (AgNPs) being the most prominent. Exposure to AgNPs occurs through multiple sources, including food packaging, supplements, and disinfectants, owing to their antimicrobial properties. Prior research has identified adverse health effects, such as cytotoxicity, toxicity, and Ag bioaccumulation resulting from AgNP exposure to bacteria in biological systems and the environment. However, most studies employ pristine, highly concentrated NPs, which may not accurately represent realistic exposure scenarios at environmentally relevant concentrations. This project investigates the fate and internalization of AgNPs, found …

The Genetic Associations Of Circadian Rhythm And Sleep Disorder Traits With Risk Of Monoclonal Gammopathy Of Undetermined Significance And Multiple Myeloma, Brittany Crawford

Theses and Dissertations

Background: Circadian rhythm disruption and sleep have been widely studied for their roles in immunity and cancer development. Evidence for an association of circadian rhythm and sleep traits with multiple myeloma (MM) risk is inconclusive. No studies have investigated these traits in relation to monoclonal gammopathy of undetermined significance (MGUS). Given that MGUS precedes almost all MM cases, investigating sleep and circadian rhythm in relation to both MM and MGUS is necessary. The purpose of this dissertation was to explore the genetic influences of circadian rhythm and sleep traits on the risk of MGUS and MM. Methods: Data were leveraged …

Firearm Contagion: A New Look At History, Rachel Martin, Michael R. Ulrich

Faculty Scholarship

Gun violence is widely considered a serious public health problem in the United States, but less understood is what this means, if anything, for evolving Second Amendment doctrine. In New York Pistol & Rifle Association, Inc. v. Bruen, the Supreme Court held that laws infringing Second Amendment rights can only be sustained if the government can point to sufficient historical analogues. Yet, what qualifies as sufficiently similar, a suitable number of jurisdictions, or the most important historical eras all remain unclear. Under Bruen, lower courts across the country have struck down gun laws at an alarming pace, while …

Contact Zones, Discursive Spaces: The Case Of The Silliman University National Writers Workshop, Alana Leilani C. Narciso

Akda: The Asian Journal of Literature, Culture, Performance

The Silliman University National Writers Workshop’s (SUNWW) historical circumstance has been implicated in the Cold War. As such it is accused of perpetuating colonial ideas on language and literary production. Its use of New Criticism is said to be detrimental to nation-building as this critical pedagogy is seen to be ahistorical and apolitical. This paper investigates the Workshop space and critiques the actual workshop discussions in the years 2019 and 2021. The explorations reveal that the Workshop is a discursive space, a “contact zone” where its participants are always engaged in the act of negotiating ideas about craft, literature and …

An Unusual Presentation Of Pigmented Purpuric Lichenoid Dermatitis, Christine De Antonis, Jordan T. Hyde, Jason B. Lee, Sylvia Hsu

Department of Dermatology and Cutaneous Biology Faculty Papers

Pigmented purpuric lichenoid dermatitis (PPLD) is a rare subtype of pigmented purpuric dermatosis, which classically presents with a mixture of lichenoid papules and patches on the bilateral lower extremities. Herein, we describe an unusual case of a 47-year-old man with PPLD who presented with 1-3mm discrete papules without the presence of larger patches. The diagnosis of PPLD should be considered for patients presenting with bilateral symmetric discrete papules on the legs.

Virus Control Aboard A Commuter Bus, Hamid Rahai, Jeremy Bonifacio

Mineta Transportation Institute

A major health concern for public transit users is exposure to viruses from other passengers. This numerical study examines virus containment aboard a public bus with changes to the bus ventilation system. The virus was modeled as a 2.5 µm round solid particle released from the mouth of the infectious passenger at a rate of 21 particles per second at a mouth velocity of 0.278 m/sec. The air delivery to the cabin was two linear ceiling slots spanning the length of the bus delivering 59.38 m3/min (2,097 CFM) of air at a mean velocity of 1 m/sec. Two different axial …

Physics & Astronomy Faculty Publications

The increasing resistance of bacteria to antibiotic agents is a main global public health problem. The use of nanoparticles is one of the promising ways to overcome microbial resistance to antimicrobial agents. Metal nanoparticles are increasingly used to target bacterial strains. Advances in nanotechnology, in particular the ability to synthesize nanoparticles of specific size and shape, are likely to lead to the development of new antibacterial agents. The antibacterial activities of nanoparticles are largely influenced by their sizes and large surface area/mass ratio. The antibacterial mechanisms of nanoparticles are poorly understood, but the currently accepted mechanisms include oxidative stress induction, …

This randomized controlled trial tested the Vermont Family Based Approach (VFBA) in primary care pediatrics. The VFBA is a model of healthcare delivery that shifts the focus from the individual to the family, emphasizes emotional and behavioral health, and uses evidence-based health promotion/prevention along with the treatment of emotional and behavioral problems. Participants were 81 families of 3–15-year-olds. For children, the VFBA was associated with greater reductions than the Control condition on the Child Behavior Checklist Emotionally Reactive, Withdrawn, Sleep Problems, Aggressive Behavior and Total Problems scales. For parents, the VFBA was associated with greater reductions than the Control condition …

When Planetary Cosmopolitanism Meets The Buddhist Ethic: Recycling, Karma And Popular Ecology In Singapore, Siew Ying Shee, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

By thinking with and through Buddhist cosmology, this paper explores the emergence of an ethical sensibility—what we call planetary cosmopolitanism—that is based on not just a spatially expanded ethic of care to ecological worlds, but also a temporally extended sense of justice to the future Earth. This transtemporal sense of ethical becoming reflects how the possibility of future ‘rebirth’ and accountability for past actions can motivate new ecological consciousness in the present. We forge these ideas through an empirical focus on popular Buddhist ecological practices in Singapore, where green recovery visions have primarily been driven by a secular and technocratic …

Why Do Farmers’ Cooperatives Fail In A Market Economy? Rediscovering Chayanov With The Chinese Experience, Zhanping Hu, Qian Forrest Zhang, John A. Donaldson

Research Collection School of Social Sciences

In The Theory of Peasant Cooperatives, Chayanov develops the theories of differential optima and vertical integration, which stress the vulnerability of peasant farming in capitalist markets, and argues that cooperatives can support smallholders only if they operate as ‘a cooperative movement’, are buttressed by a strong ‘cooperative culture’, and achieve ‘vertical integration’. Based on extensive fieldwork in China, we identify six major obstacles that explain the failure of most cooperatives. Chayanov’s arguments caution us to not only the vital importance of cooperatives to the resilience of peasant farming, but also the apparently insurmountable obstacles that cooperatives face in market economies.

Social Anhedonia, Communication And Marital Satisfaction In Newlywed Couples, Kenneth Tan, Amber M. Jarnecke, Susan C. South

Research Collection School of Social Sciences

Objective: Social anhedonia is associated with disinterest in social interactions and poor relationship functioning, yet little is known about the specific mechanisms underlying associations between social anhedonia and romantic relationship behaviors and satisfaction. We examined the links between social anhedonia, perceptions of conflict communication patterns, and marital satisfaction. Method: The current research examined the role of social anhedonia on marital quality and functioning longitudinally across a year in a sample of 100 newlywed couples using an actor-partner interdependence framework. Results: Social anhedonia was negatively associated with own and partner's marital satisfaction. It was also negatively associated with constructive communication and …

Cross-Group Differences In Age, Period, And Cohort Effects: A Bounding Approach To The Gender Wage Gap, Ohjae Gowen, Ethan Fosse, Christopher Winship

Research Collection School of Social Sciences

For decades, researchers have sought to understand the separate contributions of age, period, and cohort (APC) on a wide range of outcomes. However, a major challenge in these efforts is the linear dependence among the three time scales. Previous methods have been plagued by either arbitrary assumptions or extreme sensitivity to small variations in model specification. In this article, we present an alternative method that achieves partial identification by leveraging additional information about subpopulations (or strata) such as race, gender, and social class. Our first goal is to introduce the cross-strata linearized APC (CSL-APC) model, a re-parameterization of the traditional …

Broodmother: What The Lack Of Bathroom Breaks Reveals About Dehumanizing Teachers, Jonathan Michael Coker

Educational Leadership

This chapter asks, “What is it like to be a public school teacher in a school that doesn't allow for adequate bathroom breaks?” Using van Manen's interpretive phenomenological methodology, the authors analyzed interviews from nine participants to create an empathetic portrayal of teachers who have inadequate bathroom breaks. These experiences were then distilled into a series of insights through the concept of “broodmothering.” These broodmothers deny their own physical and mental needs in the interest of supervising children, and show a profession burdened by increasing parentification and dehumanization of teachers. After connecting this phenomenon to larger issues in the profession, …

Review Of Toxocariasis At A Children's Hospital Prompting Need For Public Health Interventions, Mary B Fortini, Timothy A Erickson, Lauren M Leining, Karina M Robinson, Megan N Carey, Sarah J Smith, Brendan Sullivan, Alisa R Nelson, Sarah M Gunter, Jill E Weatherhead

Faculty, Staff and Students Publications

BACKGROUND: Toxocariasis, caused the by dog and cat roundworm, is one of the most common zoonotic helminth infections in the United States and can lead to severe lifelong morbidity in children. Although historical seroprevalence studies have identified a high frequency of toxocariasis regionally in the United States, there are few studies linking epidemiology and clinical disease in children. The study objective was to examine the contemporary epidemiology of pediatric toxocariasis within an endemic US region.

METHODS: We conducted an epidemiologic study analyzing children diagnosed with toxocariasis presenting to a tertiary pediatric hospital in Texas from 2010 to 2021. We examined …

Civilian Oversight Of Police Through The Lens Of Polarities Of Democracy, Joseph A. Mcmillan, Jacqueline D. Smith, William J. Benet

Journal of Sustainable Social Impact

Following the murder of George Floyd, the U.S. Congress called upon the National Organization for Black Law Enforcement Executives (NOBLE) to play a role in the reimagining of policing in America, including a transformation of policing from a warrior to a guardian mentality. In turn, NOBLE partnered with the Institute for Polarities of Democracy (the Institute) to conduct an analysis of the 21st Century Policing Report (the Report), which focused on addressing a myriad of issues that challenged the relationship between the police and communities. The Report determined there were six “pillars” necessary for effective policing in America, including (1) …

If You Build It, They Will Come: Coastal Amenities Facilitate Human Engagement In Marine Protected Areas, Christopher M. Free, Joshua G. Smith, Cori J. Lopazanski, Julien Brun, Tessa B. Francis, Jacob G. Eurich, Joachim Claudet, Jenifer E. Dugan, David A. Gill, Scott L. Hamilton, Kristin Kaschner, David Mouillot, Shelby L. Ziegler, Jennifer E. Caselle, Kerry J. Nickols

Faculty Research, Scholarly, and Creative Activity

Calls for using marine protected areas (MPAs) to achieve goals for nature and people are increasing globally. While the conservation and fisheries impacts of MPAs have been comparatively well-studied, impacts on other dimensions of human use have received less attention. Understanding how humans engage with MPAs and identifying traits of MPAs that promote engagement is critical to designing MPA networks that achieve multiple goals effectively, equitably and with minimal environmental impact. In this paper, we characterize human engagement in California's MPA network, the world's largest MPA network scientifically designed to function as a coherent network (124 MPAs spanning 16% of …

Functional Characterization Of The Human And Murine Schlafen Family Group Iii, Carlos A. Valenzuela

Open Access Theses & Dissertations

The Schlafen (SLFN) family of proteins are known for being encoded by interferon stimulated genes. The family is divided into three groups (I, II, III), for which the largest in size belong to the subgroup III. In humans, group III has the most members (SLFN5, SLFN11, SLFN13 and SLFN14); there is no member of group I and only one member of group II (SLFN12). All human SLFNs belonging to group III have been reported to impair viral protein expression or infection across a variety of viruses. The antiviral function is mediated in SLFN11 and SLFN13 by their tRNase activity, and …

Clinician Perspectives On Levels Of Evidence And Oversight For Deep Brain Stimulation For Treatment-Resistant Childhood Ocd, Michelle T Pham, Tiffany A Campbell, Natalie Dorfman, Laura Torgerson, Kristin Kostick-Quenet, Jennifer Blumenthal-Barby, Eric A Storch, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Approximately 10-20% of children with obsessive-compulsive disorder (OCD) have treatment-resistant presentations, and there is likely interest in developing interventions for this patient group, which may include deep brain stimulation (DBS). The World Society for Stereotactic and Functional Neurosurgery has argued that at least two successful randomized controlled trials should be available before DBS treatment for a psychiatric disorder is considered "established." The FDA approved DBS for adults with treatment-resistant OCD under a humanitarian device exemption (HDE) in 2009, which requires that a device be used to manage or treat a condition impacting 8,000 or fewer patients annually in the United …

Neural Complexity Eeg Biomarkers Of Rapid And Post-Rapid Ketamine Effects In Late-Life Treatment-Resistant Depression: A Randomized Control Trial, Nicholas Murphy, Amanda J F Tamman, Marijn Lijffijt, Dania Amarneh, Sidra Iqbal, Alan Swann, Lynnette A Averill, Brittany O'Brien, Sanjay J Mathew

Staff and Researcher Publications

Ketamine is an effective intervention for treatment-resistant depression (TRD), including late-in-life (LL-TRD). The proposed mechanism of antidepressant effects of ketamine is a glutamatergic surge, which can be measured by electroencephalogram (EEG) gamma oscillations. Yet, non-linear EEG biomarkers of ketamine effects such as neural complexity are needed to capture broader systemic effects, represent the level of organization of synaptic communication, and elucidate mechanisms of action for treatment responders. In a secondary analysis of a randomized control trial, we investigated two EEG neural complexity markers (Lempel-Ziv complexity [LZC] and multiscale entropy [MSE]) of rapid (baseline to 240 min) and post-rapid ketamine (24 …

Recent Insights Into The Pathogenesis And Therapeutic Targets Of Chronic Liver Diseases, Yankai Wen, Lichun Ma, Cynthia Ju

Faculty, Staff and Student Publications

Viral hepatitis, alcohol-associated liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) are the three major causes of chronic liver diseases, which account for approximately 2 million deaths per year worldwide. The current direct-acting antiviral drugs and vaccinations have effectively reduced and ameliorated viral hepatitis infection, but there are still no effective drug treatments for ALD, NAFLD and liver cancer due to the poor understanding of their pathogenesis. To better understand the pathogenesis, the fifth Chinese American Liver Society/Society of Chinese Bioscientists in America Hepatology Division Annual Symposium, which was held virtually on 21-22 October 2022, focused on the topics …

The Interaction Between Autophagy, Helicobacter Pylori, And Gut Microbiota In Gastric Carcinogenesis, Ali Nabavi-Rad, Abbas Yadegar, Amir Sadeghi, Hamid Asadzadeh Aghdaei, Mohammad Reza Zali, Daniel J Klionsky, Yoshio Yamaoka

Faculty, Staff and Students Publications

Chronic infection with Helicobacter pylori is the primary risk factor for the development of gastric cancer. Hindering our ability to comprehend the precise role of autophagy during H. pylori infection is the complexity of context-dependent autophagy signaling pathways. Recent and ongoing progress in understanding H. pylori virulence allows new frontiers of research for the crosstalk between autophagy and H. pylori. Novel approaches toward discovering autophagy signaling networks have further revealed their critical influence on the structure of gut microbiota and the metabolome. Here we intend to present a holistic view of the perplexing role of autophagy in H. pylori pathogenesis …

Inner Development Goals And The Meaning, Awareness And Purpose (Map) Model For Climate Coaching, J Rhodes, J Blakeley-Glover, A Miller, A Taylor, I Rochmankowski

School of Psychology

In the initial study, two focus groups (n=11) scrutinized the five domains within the Inner Development Goals (IDG) framework, examining the essential skills for tackling challenging goals. They collaboratively crafted a streamlined 29-item measure (IDG-A), incorporating a novel sixth domain: organizational belonging. The second study assessed the IDG-A among employees from four organizations (n=39), exploring correlations between the 29 items, six domains, and overall scores. Significantly, many items, nearly all domains, and all domains in relation to the composite score exhibited meaningful correlations, suggesting strong single conceptual alignment. The third study employed findings from the first, leveraging the conceptual congruence …
