The Existential Challenges Of Cyberspace, Sean Cleary

Graduate Student Theses, Dissertations, & Professional Papers

Cyberspace is an emergent environment that has come to facilitate a growing range of human activity. Here, information is tightly woven, freed of unnecessary context and always within reach. This thesis explores the existential challenges that arise from increased engagement in this space and offers solutions informed by Henry Thoreau and Søren Kierkegaard. Section One offers an ontological account of cyberspace and describes its relationship to what I call the lifeworld. Section Two further examines the relationship drawn out in Section One, introduces the challenge of foreground saturation and appeals to Thoreau for solutions. Section Three introduces the concept of …

No Diving From Bridge, Lia R. Mendez

Graduate Student Theses, Dissertations, & Professional Papers

Lia Mendez grew up on the frontlines of America's breadbasket in the great Central Valley of California where Big Ag and Big Oil reign supreme. When Lia returns home after a long absence and joins local activists in her hometown's fight to reclaim its dying river from agribusiness, she discovers that the land holds secrets whose truths have been long hidden in plain sight. As Lia's love and concern deepen for the very place she promised herself she'd never wind up in, so, too, does her understanding deepen of the systems of oppression and extraction which rule her world. In …

A Novel Pathway For The Production Of Poly-N-Acetylglucosamine By Borreliaceae, Adam Matthew Drobish

Graduate Student Theses, Dissertations, & Professional Papers

Poly-N-acetylglucosamine (PNAG) is an extracellular polysaccharide consisting of β-1,6 N-acetylglucosamine monomers. PNAG is a key component of biofilms produced by diverse bacteria including Escherichia coli, Staphylococcus aureus, Yersinia pestis, Bacillus subtilis¸and many more. The structure of PNAG is highly conserved across the microbial world. Here, we demonstrate that PNAG is produced by two Borrelia species, Borrelia (Borreliella) burgdorferi and Borrelia hermsii. PNAG production in B. burgdorferi, the Lyme disease spirochete, depends on pngA (bb0620), a gene annotated to express a glycosyl hydrolase family 3 (GH3) enzyme, which is a novel pathway. Surprisingly, in B. burgdorferi, PNAG appears to be intracellular, …

The Effects Humidity & Temperature Has On Dna Contamination During Storage, Samantha Leigh Allison Ramey

Graduate Student Theses, Dissertations, & Professional Papers

Studies have been conducted on DNA cross-contamination throughout the criminal investigation process in order to evaluation the possibility that DNA from one sample could potentially influence the outcome of another. However, no published studies have examined the potential for contamination during the storage of genetic evidence after samples have been taken from crime scenes or suspects. This study is a continuation of a preliminary project, which examined storage drying time in relation to cross-contamination. The current study tested temperature and humidity for the potential of cross-contamination during storage prior to extraction. Prior to storage, 50 μl of male saliva was …

Studies in diet breadth modeling and patch choice have been and continue to be a hot topic of interest among practitioners of human behavioral ecology and the set of data available at Bridge River can certainly add to these debates and discussions that have been dominating anthropology in the past few decades. The faunal assemblage of Housepit 54’s 17 anthropogenic floors have provided researchers with a plethora of data that clearly indicates periods of resource depletion and partial to full site abandonment. Using Linear Programming and Diet Breadth Modelling I analyze the most represented species in the record and establish …

Brain Antigens Stimulate Proliferation Of T Lymphocytes With A Pathogenic Phenotype In Multiple Sclerosis Patients, Assaf Gottlieb, Hoai Phuong T Pham, John William Lindsey

Faculty, Staff and Student Publications

A method to stimulate T lymphocytes with a broad range of brain antigens would facilitate identification of the autoantigens for multiple sclerosis and enable definition of the pathogenic mechanisms important for multiple sclerosis. In a previous work, we found that the obvious approach of culturing leukocytes with homogenized brain tissue does not work because the brain homogenate suppresses antigen-specific lymphocyte proliferation. We now report a method that substantially reduces the suppressive activity. We used this non-suppressive brain homogenate to stimulate leukocytes from multiple sclerosis patients and controls. We also stimulated with common viruses for comparison. We measured proliferation, selected the …

Accessibility To Vaping Products, Vaping, And Use Of Cigarettes Among Adolescents, Sherri Adeosun

Walden Dissertations and Doctoral Studies

There has been a continuous increase in the use of e-cigarettes among adolescents. The growth threatens to nullify the years of successfully reducing cigarette smoking among this age demographic. Additionally, the increase has been a concern for public healthcare workers due to the limited research on the effects of long-term use of e-cigarettes on adolescents. I investigated the possible side effects of exposure to e-cigarette advertisements and the use of e-cigarettes. Additionally, the study reviewed the relationship between the age e-cigarette use was initiated and the subsequent use of cigarettes. The conceptual framework was based on the multi-theory model and …

Small Tech, High Touch: A Permutation, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

In an earlier paper published in a neutrosophic math journal (IJNS), we discussed a new approach to technology, which may be called as ‘opti-realism’ or ‘pess-optimism’ as alternative to utopianism based on technocracy, which may lead the world into global techno-totalitarianism. In this article, we submit a new approach to Nature and technology, which is more modest and humble, rather than a techno-utopianism version of reality that most futurists argue for. Our proposed approach resembles more to Myer-Briggs 16 types of personality, including IJNS, IFNS etc. In our scheme, there are 8 characters of approach toward technology which can lead …

Artists As Assets: Labor And Capital In The Unity Asset Store, D'An Knowles Ball

English Faculty Publications

The Unity Asset Store sells amateur designers and artists a promise of being able to participate in an idealized, rationalized vision of how the game design industry operates. However, the Unity Asset Store depends on marketing the content created by amateur artists in ways that require the artists to essentially package their work as labor and to mask their role as artists. This essay views labor and capital in the Unity Asset Store through a Marxist lens, informed by Kline, Dyer-Witheford, and de Peuter's (2003) model of technological, cultural, and marketing forces as "three circuits of interactivity" in the mediatized …

The Acute Physiological Response Of Polar Bears To Helicopter Capture, John P. Whiteman, Henry J. Harlow, George M. Durner, Eric V. Regehr, Steven C. Amstrup, Anthony M. Pagano, Merav Ben-David

Biological Sciences Faculty Publications

Many wildlife species are live captured, sampled, and released; for polar bears (Ursus maritimus) capture often requires chemical immobilization via helicopter darting. Polar bears reduce their activity for approximately 4 days after capture, likely reflecting stress recovery. To better understand this stress, we quantified polar bear activity (via collar‐mounted accelerometers) and body temperature (via loggers in the body core [T_abd] and periphery [T_per]) during 2–6 months of natural behavior, and during helicopter recapture and immobilization. Recapture induced bouts of peak activity higher than those that occurred during natural behavior for 2 of 5 bears, …

All-Inclusive Coral Reef Restoration: How The Tourism Sector Can Boost Restoration Efforts In The Caribbean, Macarena Blanco-Pimentel, Nicolas R. Evensen, Camilo Cortés-Useche, Johanna Calle-Triviño, Daniel J. Barshis, Victor Galván, Erika Harms, Megan K. Morikawa

Biological Sciences Faculty Publications

Following a strong decline in the health of Caribbean coral reefs in the 1970s, disease outbreaks, overfishing, and warming events have continued to push these reefs towards a point of no return. As such, researchers and stakeholders have turned their attention to restoration practices to overcome coral recovery bottlenecks on Caribbean reefs. However, successful restoration faces many challenges, including economical and logistical feasibility, long-term stability, and biological and ecological factors yet to fully understand. The tourism sector has the potential to enhance and scale restoration efforts in the Caribbean, beyond simple financial contributions. Its strengths include long-term presence in several …

Plant-Frugivore Interactions Across The Caribbean Islands: Modularity, Invader Complexes And The Importance Of Generalist Species, Maximilian G.R. Vollstädt, Mauro Galetti, Christopher N. Kaiser-Bunbury, Benno I. Simmons, Fernando Gonçalves, Alcides L. Morales-Pérez, Luis Navarro, Fabio L. Tarazona-Tubens, Spencer Schubert, Tomas Carlo, Jackeline Salazar, Michel Faife-Cabrera, Allan Strong, Hannah Madden, Adam Mitchell, Bo Dalsgaard

Biological Sciences Faculty Publications

Aim: Mutualistic interactions between plants and animals are fundamental for the maintenance of natural communities and the ecosystem services they provide. However, particularly in human‐dominated island ecosystems, introduced species may alter mutualistic interactions. Based on an extensive dataset of plant–frugivore interactions, we mapped and analysed a meta‐network across the Caribbean archipelago. Specifically, we searched for subcommunity structure (modularity) and identified the types of species facilitating the integration of introduced species in the Caribbean meta‐network.

Location: Caribbean archipelago (Lucayan archipelago, Greater Antilles, Lesser Antilles).

Methods: We reviewed published scientific literature, unpublished theses and other nonpeer‐reviewed sources to compile an extensive dataset …

Investigating Public Support For Biosecurity Measures To Mitigate Pathogen Transmission Through The Herpetological Trade, Elizabeth F. Pienaar, Diane J. Episcopio-Sturgeon, Zachary T. Steele

Biological Sciences Faculty Publications

The expanding global trade in herpetofauna has contributed to new infectious disease dynamics and pathways that allow for the rapid spread of pathogens geographically. Improved biosecurity is needed to mitigate adverse biodiversity, economic and human health impacts associated with pathogen transmission through the herpetological trade. However, general lack of knowledge of the pathogen transmission risks associated with the global trade in herpetofauna and public opposition to biosecurity measures are critical obstacles to successfully preventing pathogen transmission. In 2019 we administered a survey to 2,007 members of the public in the United States of America to ascertain their support for interventions …

‘It All Comes From Me’: Bahu Begam And The Making Of The Awadh Nawabi, Circa 1765–1815, Nicholas J. Abbott

History Faculty Publications

This article examines the durable, yet largely overlooked, claims of Bahu Begam (1727–1815) to dynastic wealth and authority in the Awadh nawabi (1722–1856), a North Indian Mughal ‘successor state’ and an important client of the East India Company. Chief consort (khass mahal) to Nawab Shuja-ud-Daula (r. 1754–75) and mother to his successor Nawab Asaf-ud-Daula (r. 1775–97), Bahu Begam played a well-documented role in the regime’s tumultuous politics, particularly during Warren Hastings’s tenure as the Company’s governor-general (1773–85) and his later parliamentary impeachment. But despite her prominent political influence, little attention has been paid to the substance of her …

Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase

Honors Program: Senior Projects (Public)

Physical and chemical soil degradation is becoming a major challenge for agricultural productivity in Rwanda, which is the most important part of the country’s economy. The wide spreading soil degradation in Rwanda is mainly a result of naturally poor soils coupled with unsustainable soil management leading to, for example, accelerated soil erosion, acidification, nutrient loss, compaction, and to decreasing yields. Biochar, as an end product of pyrolysis of biomass in the absence of oxygen, has been proposed as a soil amendment in remediation strategies because of its positive effects on soil productivity relevant parameters such as soil pH, structure, nutrient …

Literature reviews were conducted on history of cannabis, …

Arundinella Stenostachya (Arundinella, Poaceae), A Reevaluated New Species From Se Asia, Liqiong Jiang, Zhenwen Liu, Ende Liu, Atchara Teerawatananon, Yuehua Wang, Hua Peng

Turkish Journal of Botany

Arundinella stenostachya, a new species, is described and illustrated. It is morphologically similar to A. decempedalis and A. bengalensis, but differs from the former species by the length of panicle branches, type of trichome on nodes and pedicels length, and from the latter in height and diameter of culms, the length and width of leaf blades, pedicels length, and the length of panicles and branches. The new species has been mistakenly identified as A. decempedalis and A. bengalensis. Molecular analyses based on ITS sequences also support A. stenostachya as a distinct species.

Velocity Field Measurements Of The California Sea Lion Propulsive Stroke Using Bubble Piv, Gino Perrotta, Frank E. Fish, Danielle S. Adams, Ariel M. Leahy, Abigal M. Downs, Megan C. Leftwich

Biology Faculty Publications

California sea lions are among the most agile of swimming mammals. Most marine mammals swim with their hind appendages-flippers or flukes, depending on the species-whereas sea lions use their foreflippers for propulsion and maneuvering. The sea lion's propulsive stroke generates thrust by forming a jet between the flippers and the body and by dragging a starting vortex along the suction side of the flipper. Prior experiments using robotic flippers have shown these mechanisms to be possible, but no flow measurements around live sea lions previously existed with which to compare. In this study, the flow structures around swimming sea lions …

Limited Court Access V. Poor And Indigent, Chinyere Anunobi

Honors Undergraduate Theses

In criminal cases, poor individuals must qualify as legally indigent to receive legal representation. In civil cases, poor and indigent individuals must find their own resources to support themselves since the government does not guarantee counsel. Without counsel, poor and indigent individuals are forced to find legal representation for these cases on their own, which can be difficult considering the expenses of fees and fines. Cognitive processes, including bias and stereotypes, create a barrier in advocacy because they cloud judgement of decision-makers, which can diminish the voice of this vulnerable community. Barriers like these create an invisible wall where limited …

Methods For Characterization Of Cl-001 Derived Exosomes As A Stimulating Agent For Nk Cells For Immunotherapy, Ilana Gomez Diaz

Honors Undergraduate Theses

The immune system is a complex set of cells in the body that work to prevent disease or infection by recognizing and eliminating foreign material or unhealthy cells. One essential type of immune cell that is part of the innate immune response are Natural Killer (NK) cells. These cytotoxic effector lymphocytes can detect certain unhealthy cells, such as cancer cells, that normal B and T cells would miss. For example, many tumor cells have evolved to bypass immune system surveillance by not expressing major histocompatibility complex class I molecules (MHC class I), on their surface, reducing recognition by cytotoxic T …

The Effect Of Young Blood Anti-Aging Treatment On Protein Markers Of Age And Huntington Disease, Sujena H. Koilpillai

Honors Undergraduate Theses

Huntington disease (HD) is a neurodegenerative disorder caused by expansion of a polyglutamine tract within the huntingtin (HTT) protein, forming mutant HTT (mtHTT). HD patients suffer from psychiatric, behavioral, cognitive, and motor abnormalities, with death typically occurring 15-20 years after symptom onset. Currently, there are no treatments able to slow disease progression or delay onset. HD is a disease of aging. Despite the mtHTT protein being produced throughout life, symptoms do not typically appear until adulthood. Furthermore, many cellular effects of normal aging are also seen in HD, including altered intercellular communication and loss of proteostasis. Recently, our lab found …

Regulation Of The Protease Activity For The Mitochondrial Omi/Htra2, Simon Larson

Honors Undergraduate Theses

Human High Temperature requirement A2 (HtrA2) also known as Omi, is a serine protease located in the mitochondria with an important function in both cell survival and death. My results show the proteolytic activity of Omi/HtrA2 varies under different conditions. I characterized the optimal condition for Omi/HtrA2 protease activity using an in vitro assay system. Additionally, I identified a new allosteric regulation of Omi/HtrA2 through interaction with a specific substrate, the MUL1 protein. MUL1 is a multifunctional E3 ubiquitin ligase anchored in the outer mitochondrial membrane with domains both inside mitochondria and in the cytoplasm. The data shown here strongly …
