Periocular Mesenchyme Heterogeneity During Morphogenesis Of The Vertebrate Ocular Anterior Segment, Kristyn L. Van Der Meulen

Theses and Dissertations--Biology

The vertebrate eye is a complex organ, responsible for the primary sense with which we interact with our environment: vision. Development of the eye is a tightly regulated process, controlled by a vast network of genes. This process begins with eye morphogenesis, when the eye structure is formed through a series of morphogenetic movements and culminates in the creation of the optic cup, lens, and presumptive optic stalk. Next, retinal differentiation creates the critical cell layers of the retina needed to process light waves that enter the eye, including rod and cone photoreceptors, interneurons, and support cells. Failure in either …

It was found that the Tamarack bog presented as a mosaic bog with features of a fen as well. The …

Protocadherin-17 Expression And Function In Vertebrate Brain: A Literature Review, Mathea Mcguire

Williams Honors College, Honors Research Projects

For this project, I will be doing a systematic review on protocadherin-17 function in vertebrate brain development and function in the last 10 years. Protocadherins are members of cadherin superfamily. Cadherins are calcium-dependent cell adhesion molecules that are implicated to play crucial roles in the information and maintenance of tissues and organs in vertebrate animals. This review will summarize major findings regarding protocadherin-17 expression and function in major model organisms such as zebrafish and mice, as well as results from human studies. It is hoped that this work will be a valuable source for background knowledge of protocadherin-17 function in …

Analysis Of Circadian Rhythm Irregularities On The Health Of Shift Workers, Sahil Rajan

Williams Honors College, Honors Research Projects

Circadian rhythms involve the natural 24 wake-sleep cycle that governs proper maintenance of biological sleep schedules. Circadian rhythm disruption has been associated with health issues such as diabetes, obesity, and mental health disorders such as bipolar and sleep disorders. In this study, a survey method was utilized in order to analyze specific population demographics to determine whether working day or night shifts predisposed individuals to health issues due to disruptions in their circadian rhythms. This study was also carried out to observe popular coping strategies among night shift workers. Of all the variables tested comparing the difference between day and …

A Field Study Of Mimulus Alatus And Its Visitors, Joshua Stefan, Nathan Stefan

Williams Honors College, Honors Research Projects

The purpose of this field study was to determine the flower characteristics of Mimulus alatus and observe the behaviors of visitors to the plant. Members of M. alatus were observed in their natural habitat to ascertain the flowering period for the plants and the lifespan of a single bloom; nectar and pollen levels were also periodically measured. Behavioral patterns of visitors to the flowers were recorded and the species identified. Statistical analysis was performed to deduce the relationships between time of day and nectar and pollen levels, as well as visitor behavior. The blooming period occurred from early July to …

Determining Environmental Changes Using Time Lapse Photography, Emily Lemasters

Williams Honors College, Honors Research Projects

This paper aims to use photographs throughout several years to observe, examine, and make conclusions on changes occurring at different areas of the Bath Nature Preserve. Throughout the years 2013-2021, photographs have been captured at roughly the same angle at multiple locations in the preserve. These photographs will be placed into a time lapse video and examined to physically see how the environment is changing. Changes to the environment could be natural or as a result of outside factors. By examining these changes, it can be determined if alterations need to be made to help the environment thrive. Two specific …

Economic Success In The United States, Jason Render Jr.

In particular, I investigate the impact of inherent privilege and the impact which socioeconomic upbringing has on the economic success of an individual within American society. This investigation into economic success and the impact of inherent privilege will examine both poor and affluent U.S. citizen populations to find common factors present within both groups. The research will then examine how these factors impact an individual’s overall economic success as a result of the barriers which are inherent based on an …

Identifying Molecular Pathways Underlying Noise-Induced Tinnitus, Mckenzie Rice

Williams Honors College, Honors Research Projects

Tinnitus is a serious neurological condition effecting 10-15% of adults, and can lead to other symptoms such as difficulty concentrating and sleeping, anxiety, and depression. Currently there are no FDA approved drugs to prevent or treat tinnitus, mainly due to a lack of understanding of its cellular and molecular pathways. T- and L- type calcium channels have been implicated in the modulation of tinnitus, as well as the dysfunction of gamma-aminobutyric acid (GABA) neurons. This study used the sound-based avoidance detection (SBAD) method in order to detect tinnitus and determine whether pharmacological treatments had an effect in mediating tinnitus. T-type …

Titanium Dioxide Nanoparticles Binding To Human Blood Plasma Proteins, Morgan Miller

Williams Honors College, Honors Research Projects

Titanium Dioxide (TiO₂, titania) nanoparticles are widely studied in cosmetology, food administration, and medical fields. This is due to the nanoparticles’ suitable properties, specific combination of strength and high corrosion resistance. With the increasing attention to these particles, there is concern with potential health complications. Some of the complications involved with titania nanoparticles include blood clots and immune reactions (Sit et al., 2019). In this study, we continue the study conducted in the Sahai research group (J. Chen. MS thesis, 2020), on the binding of titania nanoparticles with blood plasma proteins, focusing on potential effects of shape only. …

Ecological Repentance, Emmanuel Salem

Williams Honors College, Honors Research Projects

In an age ripe with discovery and analysis regarding anthropogenic pollution and the resultant climate change, a causal ideological explanation is naturally sought. This paper seeks to delve deep into the Christian religion and its relationship to the current climate crisis, as well as discuss whether or not predictions and speculative assertions professed in the famous essay by Lynn White, Historical Roots of our Ecological Crisis, hold up when surveyed with a more critical and thorough evaluative lens. This conversation is undertaken under three core considerations: biblical cosmology, what has happened in the world of Christian bioethics since White’s time, …

Climate-Induced Human Displacement And Conservation Lands, Jessica Owley

Articles

As climate change leads to both internal displacement and mass migrations, we need not only new places for people to live but also new locations for infrastructure projects and other public needs. Some of the most attractive areas for these new land uses are currently unoccupied land, including land set aside for conservation. Numerous laws restrict the availability and possible uses of public conservation land. Individual agreements and property restrictions encumber private conservation land, varying in the ease with which the restrictions can be modified. For example, privately protected areas in the United States are often encumbered with perpetual conservation …

A ten-question survey was developed based on Social Ecological Theory (U.S. Department of Health and Human Services, 2005), and was administered to 31 clinicians. A key informant interview was conducted using theoretical sampling (LoBiondo-Wood & Haber, 2018) of emergent themes. Three major barriers emerged from …

Meta Rules For Ordinary Meaning, Anita S. Krishnakumar

Faculty Publications

(Excerpt)

“Ordinary meaning” is a notoriously undefined concept in statutory interpretation theory. Courts and scholars sometimes describe ordinary meaning as the meaning that a “reasonable reader” would ascribe to the statutory language at issue, but it remains unclear how judges and lawyers should go about identifying such meaning. Over the past few decades, as textualism has come to dominate statutory interpretation, courts increasingly have employed dictionary definitions as (purportedly) neutral, and sometimes dispositive, evidence of ordinary meaning. And in the past few years especially, some judges and scholars have advocated using corpus linguistics — patterns of usage across various English …

From Academic Freedom To Cancel Culture: Silencing Black Women In The Legal Academy, Renee Nicole Allen

Faculty Publications

In 1988, Black women law professors formed the Northeast Corridor Collective of Black Women Law Professors, a network of Black women in the legal academy. They supported one another’s scholarship, shared personal experiences of systemic gendered racism, and helped one another navigate the law school white space. A few years later, their stories were transformed into articles that appeared in a symposium edition of the Berkeley Women’s Law Journal. Since then, Black women and women of color have published articles and books about their experiences with presumed incompetence, outsider status, and silence. The story of Black women in the legal …

Fluid Dynamics: Representations Of Water In Music, James E. Evans

Theses and Dissertations--Music

Water has remained a subject of all kinds of musical works since at least the middle ages. These musical works lack the concrete representational capacity of paintings, photographs, and films, relying instead on more abstract metaphorical constructs to convey water imagery. Current scholarship on water music typically centers on Romantic and Impressionist works and does not examine the process of signification by which musical signs portray water. The principal goal of this study is to determine how musical devices convey specific aspects of bodies of water and how such devices interact and contribute to musical depictions of streams, rivers, lakes, …

Perspectives On Cultivating A Positive Collegiate Clarinet Studio Environment: A Survey Of Students And Professors, Katherine Nichole Breeden

Theses and Dissertations--Music

Data was analyzed from a survey of collegiate clarinet students and professors concerning student and faculty preferences and perceptions concerning the cultivation of a positive collegiate clarinet studio environment. Over two hundred respondents indicated preferences for the structure of individual lessons and studio class.

The data indicated it is essential that the professor adapt their teaching to individual students during lesson instruction. Goals should be recorded, a verbal agreement alone is insufficient. Contact information for all studio colleagues should be available, and the professor should be accessible should the need arise. Large ensemble concert attendance should be encouraged, and recital …

Unshackling Plea Bargaining From Racial Bias, Elayne E. Greenberg

Faculty Publications

“History, despite its wrenching pain, cannot be unlived, [but] if faced with courage, need not be lived again.”

Dr. Maya Angelou

When an African American male defendant tries to plea bargain an equitable justice outcome, he finds that the deep-rooted racial bias that casts African American men as dangerous, criminal and animalistic, compromises his justice rights. Plea bargaining has become the preferred process used to secure convictions for upwards of 97 percent of cases because of its efficiency. This efficiency, however, comes at a cost. The structure and process of plea bargaining makes it more likely that the historical racial …

Ant Fauna (Hymenoptera: Formicidae) Of Central Anatolian Region Of Turkey, Kadri̇ Kiran, Celal Karaman

Turkish Journal of Zoology

The Central Anatolian part of Turkey was investigated with the aim of determining its Formicidae fauna. Specimens were collected by hand sampling and pitfall traps in 24 habitats in 383 different localities in Central Anatolia Region during 2001-2016. As a result, 137 species belonging to 34 genera were determined. Messor incorruptus Kuznetsov-Ugamsky, 1929 and Ponera testacea Emery, 1895 are new records for Turkish ant fauna.

Turkish Journal of Zoology

Capoeta kosswigi was described from Lake Van basin, Turkey, being close to C. damascina and C. umbla. It is distinguished from them by a pointed snout and a small horseshoe-shaped mouth, and differing from C. damascina by having smaller scales, and from the C. umbla by processing larger scales. In this study, we tested the suggested synonymy hypothesis of C. kosswigi and C. damascina by comparing the morphometric and meristic data. The results revealed that all morphometric and meristic characters of C. kosswigi overlap with those of C. damascina. In line with previous molecular studies that COI, cytb and 16S …

Selenium Removal And Pollution Swapping Potentials Of Passive Anaerobic Bioreactors Receiving Coal Slurry Impoundment Wastes, Md Anik Mahmud

Theses and Dissertations--Plant and Soil Sciences

Worldwide, selenium is a major contaminant of concern for coal and metal ore mining industries. In coal mining regions of the eastern USA, for example, billions of liters of wastewaters with elevated Se oxyanion concentrations (primarily SeO₄^2- and SeO₃^2-) are generated during coal washing which is often stored in > 700 man-made impoundments built into remote mountain valleys. Because impoundments are unlined systems, they tend to leak contents into nearby streams, which has detrimental effects on sensitive biota, particularly fish. The primary goal of this project was to evaluate the capacity of passive anaerobic bioreactors (PAB) …

Efficacy And Mechanism Of Acs811 In Tomato Immune Responses, Layne Ellen Harris

Theses and Dissertations--Plant and Soil Sciences

Biologicals are increasingly becoming an important part of sustainable integrated pest management in agricultural crop production and encompass a wide variety of products with varying degrees of efficacy and available research data. As biologicals become more integrated into commercial production systems, it is critical to rigorously evaluate biological product efficacy and mode(s) of action in crops. The better that biologicals are understood in terms of effective application, integration into commercial programs, and their specific mechanisms in crop growth and protection, then the greater the opportunity for increasing yields and food security.

ACS811 is a microbial fermentation-based biological product from Alltech …

Leveraging Chemical And Computational Biology To Probe The Cellulose Synthase Complex, B. Kirtley Amos

Theses and Dissertations--Plant and Soil Sciences

Cellular expansion in plants is a complex process driven by the constraint of internal cellular turgor pressure by an expansible cell wall. The main structural element of the cell wall is cellulose. Cellulose is vital to plant fitness and the protein complex that creates it is an excellent target for small molecule inhibition to create herbicides. In the following thesis many small molecules (SMs) from a diverse library were screened in search of new cellulose biosynthesis inhibitors (CBI). Loss of cellular expansion was the primary phenotype used to search for putative CBIs. As such, this was approached in a forward …

Toward An Understanding Of Treatment Moderators Based On Etiological Models Of Disruptive Behavior Disorders, Tess E. Smith

Theses and Dissertations--Psychology

Extant research suggests negative outcomes associated with Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) can be avoided with early intervention, with the most efficacious being behavioral parent training. However, parent training suffers from limitations including high drop-out rates, adherence, and long-term maintenance. Yet, consistent predictors of differential outcomes among individuals have not been identified. Etiological work suggests traits may be an early marker of disruptive behaviors. The goal of the current study is to examine child traits as a moderator of treatment outcomes for ADHD and ODD, using an efficacious short parent training treatment, Brief Behavioral Intervention (BBI). Twenty-six …

The Interactive Effects Of Brain-Derived Neurotrophic Factor (Bdnf) Polymorphisms And Posttraumatic Stress Disorder On Neurocognitive Functioning In U.S. Military Veterans, Colton Shafer Rippey

Theses and Dissertations--Psychology

Posttraumatic Stress Disorder (PTSD) is associated with mild-to-moderate deficits in neurocognitive functioning. Single nucleotide polymorphisms (SNPs) in the brain-derived neurotrophic factor (BDNF) gene, namely, the Met allele, may also be associated with mild deficits in neurocognitive functioning. However, findings are inconsistent and may be sensitive to environmental epigenetic moderators such as psychopathology.

The current study analyzed data from European-American U.S. military veterans (n = 1,244) who participated in the 2011 National Health and Resilience in Veterans Study (NHRVS). Multivariate analyses of covariances were conducted to evaluate the unique and interactive effects of the Met allele and probable PTSD on …

The Utility Of The Unified Protocol In Treating Borderline Personality Disorder, Martina Fruhbauerova

Theses and Dissertations--Psychology

Borderline personality disorder (BPD) is characterized by maladaptive levels across three personality domains: Neuroticism, (low) Agreeableness, and (low) Conscientiousness. The Unified Protocol (UP) is a transdiagnostic treatment that targets neuroticism and has demonstrated promising effects with BPD. However, not all individuals with BPD respond to UP treatment. The aim of the current study was to explore the extent to which the UP is an efficacious treatment for BPD symptoms. This study represents a secondary analysis of a clinical trial in which the UP was the study treatment; data from the full sample and a subset of nine participants who likely …

Characterizing Galectin And Lysosomal Rupture's Role In Spreading Parkinson Disease Pathology, Kevin Burbidge

Dissertations

The misfolding and subsequent accumulation of alpha-synuclein (α-syn) is central to the pathogenesis of Parkinson's disease (PD). Several lines of evidence suggest pathological α-syn spread cell-to-cell via a "prion-like" mechanism. Furthermore, this pathological α-syn is capable of "seeding" further misfolding of non-pathological α-syn, converting them to the pathological form. While a vast body of both genetic and experimental evidence indicates that α-syn is critical to PD development, how α-syn induces progressive neuronal dysfunction and cell death remains unclear.Autophagy, conventional for macroautophagy, is the primary degradation pathway for α-syn aggregates. Autophagy also influences the unconventional secretion of both pathological and non-pathological …

Conifer Encroachment And Removal In A Northern California Oak Woodland: Influences On Ecosystem Physiology And Biodiversity, Gabriel S. Goff

Cal Poly Humboldt theses and projects

Oregon white oak (Quercus garryana) woodlands across their range are becoming increasingly threatened by encroaching Douglas-fir encroachment (Pseudotsuga menziesii) as a result of fire exclusion. Using water potential (Ψ), stomatal conductance (g_s), xylem water stable isotopes (dD), and three metrics of biodiversity, this study investigates the effects of conifer encroachment and removal at the ecosystem-scale. The study was set in an Oregon white oak woodland in northern California and compared three levels of encroachment before and after conifer removal. Findings indicate that heavily encroached stands have the least amount of water stress and gas …
