An Evaluation Of The Effect Of Degradation On Irisplex Snps, Maria Gruber

Master's Theses

The information from short tandem repeats (STRs), the current standard forensic DNA typing technology, does not always result in identification. In these cases, there are other informative markers in DNA that can be used to help generate investigative leads, one of which is single nucleotide polymorphisms (SNPs). One of the uses of SNPs is for phenotype determination. Among the phenotypic characteristics that can be predicted is eye color. A commonly used tool for eye color prediction is the free, online statistical prediction model IrisPlex, which includes 6 SNPs known to control eye color.

While SNPs can be useful, they, like …

Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston

Master's Theses

In investigations, locating missing persons and clandestine remains are imperative. One way that first responder and police agencies can search for the remains is by using cadaver dogs as biological detectors. Cadaver dogs are typically used due to their olfactory sensitivity and ability to detect low concentrations of volatile organic compounds produced by biological remains. Cadaver dogs are typically chosen for their stamina, agility, and olfactory sensitivity. However, what is not taken into account often is the size of the animal and the expense of maintaining and training the animal. Cadaver dogs are typically large breeds that cannot fit in …

Introspective Accuracy For Social Cognition Across The Psychosis Spectrum: Influence Of Sleep Disturbance, Cassi Springfield

Master's Theses

People with schizophrenia-spectrum and bipolar disorders can have impairments in introspective accuracy (IA; ability to accurately estimate one’s own abilities). Research suggests that positive, negative, and depressive symptoms may be related to IA, but findings are mixed. Examining sleep disturbance as a determinant of IA may help explain these mixed findings. The current study aimed to explore the relationships between sleep disturbance, symptoms, and IA in participants across the psychosis spectrum. Participants completed diagnostic, symptom, and sleep disturbance assessments. Participants also completed social cognitive tasks, estimated their performance on the tasks (used to calculate IA), and indicated their confidence in …

Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis

Master's Theses

This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.

The third part involved applying the Diamond Dye solution by spraying it onto …

An Investigation Of Resistance Training Behavior, Non-Specific Psychological Distress, And Perceived Barriers To Resistance Training In Self-Identifying Female Undergraduate Students, Jody Sobel

Master's Theses

The prevalence and severity of depression symptoms amongst college students, specifically female identifying undergraduate students, is worrisome. There is a great deal of research that suggests a relationship between exercise, specifically resistance training (RT), and mental health. That said, current literature suggests that many female identifying students are not engaging due to perceived barriers. This, perhaps because of the plethora of barriers one can perceive. The purpose of this study was multifold 1) to examine the prevalence and severity of non-specific psychological distress; 2) to determine if there were differences between Kessler 6 Non-Specific Psychological Distress Scale (K6) categories (i.e., …

I’Ll Be Goldenrod And You’Ll Be Aster: The Case For Revolutionizing Western Methods Of Teaching Using Indigenous Ontologies, Joanna Logerfo

Master's Theses

An interesting facet of living as a human in the 21st century is contending with the end of the world. It’s been imagined in a thousand ways over the past twenty years. Will it be zombies? Aliens? An AI revolution? Or will it perhaps be something more mundane, more “down-to-Earth”? The floods, the droughts, the famines, and all the rest of the cataclysmic global events that occur every year have taken center stage in the world-ending debate, parading under a name as threatening and expansive as the Boogeyman: climate change. A recent article from NPR covered the United Nations’ 2022 …

Evaluation Of Raman Microspectroscopy And Hyperspectral Imaging As A Screening Tool To Determine Optimal Sampling Sites For Dna Recovery From Human Skeletal Remains, Kathleen M. Smith

Master's Theses

Numerous challenges exist with forensic genetic testing of human skeletal remains due to diagenesis patterns in bone microstructure, DNA degradation, and the presence of PCR inhibitors. Diagenesis is the microscopic breakdown of the bone matrix, which consists primarily of mineralized calcium hydroxyapatite and collagen. The process of diagenesis occurs in a heterogeneous, non-uniform manner along the diaphysis of a long bone, and determining the region with the most intact bone microstructure is not possible with the naked eye. Therefore, taking cuttings from the diaphysis for DNA testing is somewhat of a “blind” process, and decades of research and casework have …

Brazilian Camming: The Monetization Of Intimacy In Online Sex Work, Fernanda Veiverberg

Master's Theses

This thesis addresses a form of online feminized labor in Brazil, which employs digital technology to relieve the urges for intimacy and monetary insecurity. Camming is a genre of online sex work, in which cam models sell their body image and attention online through computer-mediated interactions. It constitutes a profitable activity that employs body performance without physical contact between model and client, typical in most categories of sex work such as prostitution, and where the clients are not mere spectators as within the pornography industry because camming requires authenticity and communication. For that, I explored three conceptual spheres that combined …

Gender Differences In Personality Dysfunction And Aggression In A Sample Of At-Risk Youth, Chloe O'Dell

Master's Theses

Youth with antisocial and borderline traits in adolescence have been found more likely to commit violence and experience negative outcomes later in life. There is evidence for gender differences in the manifestations of dysfunctional personality features (antisocial and borderline traits) and functions of aggression, but little research has sought to assess unique gender differences that may help unravel the sequelae of personality dysfunction in youth. Accordingly, this exploratory study examines gender differences in associations between antisocial features, borderline features, and proactive and reactive functions of aggression in a sample of at-risk youth. Four hundred and sixty-four adolescents (M_age = …

The Relations Between Rumination, Thought Control, And Suicidal Thinking, Morgan Buerke

Master's Theses

Despite the far-reaching impact of suicide on our communities, we need more research to understand how suicidal thoughts develop, and what leads to their maintenance. As suggested by the depression distress-amplification model (Capron et al., 2013), emotion-regulation strategies such as rumination may cause or worsen suicidal ideation by amplifying the distress associated with negative thoughts. In addition, ruminative thoughts are often described as difficult to control, which may lead people to think about suicide as an escape from these uncontrollable thoughts. The current study examined the relationship between certain forms of rumination (i.e., brooding, reflection, anger rumination, and suicidal rumination) …

The Implications Of Sexual Assault Awareness On Sexual Overperception Bias, Zach Buckner

Master's Theses

Heterogeneity has recently emerged in research investigating men’s overperceptions of women’s sexual receptivity, namely that such overperceptions are less robust than previously considered. Various social movements (e.g., #MeToo) could be a modern-day contextual factor that has reduced men’s tendency toward overperception. In this study, participants viewed hypothetical information regarding sexual assault perpetration committed by men or women (or control information) before rating opposite-sex targets on perceived sexual interest in them and reporting individual differences in just and dangerous world. The results indicate that individuals who hold stronger beliefs in an unjust world are more sensitive to perceived threats from potential …

I Was Looking For God: A Study Of Wehrmacht Personnel And Their Personal Relationships With Religion, Christopher Bishop

Master's Theses

The Wehrmacht was Germany’s fighting force in the field during World War II. Its brutality and discriminatory practices rivaled that of the Nazi paramilitary and police units dispatched alongside them in newly conquered areas during this conflict. Coming from a society that was not at all unfamiliar with Christianity, some within the Wehrmacht related to Christianity in some form and attempted to use it to either justify actions or make sense of the world around them.

While considerable scholarship exists on the Nazi Party’s relationship to Christianity as a convenient propaganda tool for both soldier and civilian alike, the historiography …

Parental Autonomy Support And Children’S Stem Engagement During An At-Home Tinkering Activity, Bianca Martins Aldrich

Master's Theses

Parents play an important role guiding children’s learning of science, technology, engineering, and mathematics (STEM) in informal educational contexts. In this project, we considered the ways in which parents use autonomy supportive or controlling language to encourage or discourage children's independence in problem solving, as well as their feedback to children’s ideas and behaviors. We looked at the association between autonomy support and children’s behavioral, STEM, story, and emotional engagement during an at-home tinkering and storytelling activity. Parents and their 4- to 10- year old children were observed at home via Zoom. We coded parents’ and children’s behaviors using a …

Decolonizing A Settler Colonial State: How Canada And The United States Have Approached Investigations Into Indigenous Boarding And Residential Schools, Holly Jacobs

Master's Theses

Indigenous boarding and residential schools were in use for over 100 years in both Canada and the United States. Grown from numerous policies aimed at assimilation, dispossession, and genocide of the Indigenous peoples of North America, these residential schools had a particular aim: to wipe away all cultural and familial ties of every individual and to replace them with beliefs and values of white settlers. Though the schools are no longer in operation, their legacy of erasure and pain continues to affect survivors, their descendants, and Indigenous communities across both nations. This thesis looks at what the federal governments of …

Physical Activity, Self-Determination, And Self-Conscious Emotions In Adolescents And Young Adults With And Without Autism Symptomatology, Dakota Morales

Master's Theses

Previous literature suggests that autistic individuals engage in physical activity less frequently compared to typically developing peers (Bandini et al., 2013; Jones et al., 2017). This is noteworthy because exercise interventions for autistic individuals have found that engaging in physical activity can improve motor, social, and behavioral skills (Anderson-Hanley et al., 2011; Duffy et al., 2017; Nicholson et al., 2011; Oriel et al., 2011). Thus, the present study seeks to understand what factors may promote physical activity engagement, such as self-determination motivation regulations and body-related self-conscious emotions, in adolescents and young adults with and without autism symptomatology. Participants included 51 …

Building Strength Versus Getting Lean: An Analysis Of The Gendered Nature Of Fitness In Crossfit, Barre, And Personal Training, Margaret M. Jones

Master's Theses

Like many industries in contemporary society, the fitness sector is heavily gendered, andthus needs to be examined as a sector that both creates and reinforces gendered bodies. Building on previous single-method studies, I utilized a multi-methods approach of ethnography and interviews to analyze organizational and individual experiences with gender and fitness. Using West and Zimmerman’s concept of “doing gender,” I analyzed fitness organizations as a setting where gender and inequality are actively reproduced. By analyzing three fitness organizations with different gendered audiences (a barre studio, a CrossFit gym, and a personal training facility) I looked at how gender and fitness …

Changing Vaccine Hesitant Attitudes Of Parents Using Moral Persuasion, Max Vitro

Master's Theses

In the fight against Covid-19, overt, science-based messaging is not enough to persuade everyone to get vaccinated no matter how encouraging the data. Recent studies on attitudes toward vaccines and other health-promoting measures have provided clues as to why so many are still opposed, suggesting many who were resistant had reasons that were rooted along moral grounds. This process of moralization occurs when a belief becomes a moral matter of ‘right and wrong’ rather than a means to an end. Because moral beliefs are more entrenched, they’ve proven much more difficult to change. There is one approach that could increase …

The Mediating Role Of Perceived Organizational Support On The Relationship Between Wellness Programs And Job Satisfaction, Andy Tran

Master's Theses

The purpose of the current study was to examine the mediating role of perceived organizational support (POS) on the relationship between wellness programs (participations and availability) and job satisfaction. A total of 83 employees participated in the study, which utilized online survey distribution. Results showed that POS fully mediated the relationship between both participation and availability of wellness programs and job satisfaction. In other words, employees who participated in a wellness program felt more supported by their organization, leading to greater job satisfaction. In addition, the results suggested that when organizations offered more wellness programs, employees were more likely to …

Habitat Value Of Stormwater Retention Basins For Avian Species In The South San Francisco Bay, Maya D. Briones

Master's Theses

Shorebird populations are declining worldwide due to habitat fragmentation, degradation, and loss. A potential, understudied set of resources that might be used to benefit waterfowl, especially breeding shorebirds, are artificial wetlands such as stormwater retention basins. This study evaluated the habitat value of stormwater retention basins in the San Francisco Bay Area by measuring species abundance, richness, and behavior. Seston, or biota and other suspended material, was collected and tested for mercury contents. Additionally, the habitat features within each basin were recorded and tracked for changes over a year. The stormwater retention basins supported a higher diversity of bird species …

No Kidding: The Moderating Role Of Childcare Responsibility On The Relationship Between Perceived Work-Life Balance Policy Culture And Job Outcomes, Ziwei Gao

Master's Theses

The societal assumption that everyone will or should have children at some point is deeply ingrained in many cultures. This often results in a lack of recognition and understanding of the experiences of childfree individuals, particularly within professional settings. Therefore, the present study aimed to examine the moderating effect of childcare responsibility on the relationship between perceived work-life balance policy culture and job outcomes. A sample of 161 participants completed an online survey measuring perceived work-life balance policy culture, job satisfaction, organizational commitment, and turnover intentions. Results showed that employees with high levels of perceived work-life balance policy culture reported …

Motivated Reasoning In Technology Workers, Kory Feath

Master's Theses

The goal of this study is to investigate cognitive predictors for motivated reasoning, the process in which evidence evaluation is influenced by prior beliefs, in technology workers. Two hundred and twenty-one technology workers were recruited using Prolific and word-of-mouth to evaluate the conflicting evidence of social media causing digital harm. Past research has found that many individual cognitive styles do not predict motivated reasoning, but by using structural equations modeling to investigate the latent variable analytical/reflective thinking styles, I predicted that more active thinking styles will reduce motivated reasoning and be mediated by prior belief strength. A structural equations model …

Educational Attainment And Employment Status Of Medical Cannabis Users In The Bay Area Of California, Kristi M. Sadler

Master's Theses

This research assesses whether participants’ responses align with the literature concerning cannabis use on educational attainment and employment outcomes. Mainly, cannabis use in adolescence is associated with lower educational attainment, and cannabis use in general may lead to poor employment outcomes, as described in the literature. Participants were medical cannabis dispensary patients with a California medical cannabis card residing in 11 counties in or near the San Francisco Bay Area. Data were collected via an internet survey from October to December 2017 via 32 medical cannabis dispensaries. Medical cannabis users reported having bachelor’s degrees at double the current national average. …

Manifestations Of Communicative Resilience In Experiences Of Serial Arguments Among Adult Children Of Harmful Parental Alcohol Use, Brooklyn Willis

Master's Theses

This thesis investigated the ways in which adult children of harmful parental alcohol use manifest resilience through the lens of the Communication Theory of Resilience (CTR). The CTR presents five communication processes by which resilience, which is the ability to overcome hardship, is demonstrated. Serial arguments, the repeated and unresolved conflicts that occur between romantic partners, were utilized as the context to study resilience. Interviews were conducted to learn about perceptions of serial argument resolvability and the ways and frequencies in which resilience manifested. A pre-interview survey gathered information pertaining to relationship satisfaction and perceptions of resilience. A thematic analysis …

Distribution And Habitat Use By Western Burrowing Owls (Athene Cunicularia Hypugaea) In Alameda, Contra Costa And San Joaquin Counties, California, Jacqueline Taylor

Master's Theses

Grasslands are regularly altered for development, agriculture, and animal farming which leads to habitat destruction and fragmentation and, ultimately, a loss of wildlife species. Though degraded, grassland ecosystems – including native and non-native species - dominate the landscape in the region of the San Francisco Bay Area east of the Bay. The western burrowing owl (Athene cuncularia hypugaea) is a native grassland species of California. The breeding burrowing owl population in the San Francisco Bay Area is resident, but burrowing owls from other parts of the range migrate into the region for the winter. The breeding owl populations in the …

An Exploration Of The Low Prevalence Effect During Phising Detection, Sherry J. Wei

Master's Theses

Phishing attacks are attempts to obtain individual credentials or other private information through deception, usually in email format. As the Internet becomes increasingly intertwined with everyday lives, such attacks are on the rise, threatening individuals and businesses alike. Existing anti-phishing training measures fail to address possible prevalence effects on detection performance: in tasks where targets appear rarely, participants have heightened miss rates. This low prevalence effect could be present in phishing detection because phishing emails are observed much less frequently than legitimate emails. Emerging research has reported observing heightened miss rates as a function of phishing email rarity. This study …

Thinking Styles, Conspiracist Belief, And The Mediating Role Of The Dunning-Kruger Effect In Modeling Belief Change, Lucas C. Cusano

Master's Theses

Why can a person believe something for which there is no evidence and yet also fail to believe something for which there is overwhelming evidence? This study develops a structural model of belief change using the latent constructs of thinking styles and conspiracist belief while accounting for the Dunning-Kruger effect (i.e., overconfidence in one’s knowledge the less one knows about a topic) as a mediator. A combined two-hundred and twenty-six participants from both Amazon’s Mechanical Turk and the introductory psychology SONA subject pool were given two knowledge measures on topics of genetic modification and vaccination before and after reading refutational …

Examining The Role Of Echo-Chambers Within Online Incel Communities Using Sentiment Analysis And Group Based Trajectory Modeling, Francesca Florine Fanucchi

Master's Theses

Technological advancements within the last decade have created new opportunities for social movements to meet and communicate online with like-minded individuals. Under this notion, these online communities generate an echo-chamber of information, to which certain individuals only surround themselves with people sharing similar values and opinions. As a result, online platforms (e.g., forums, blogs, websites) form as safe spaces for members to express their views seen as unacceptable offline. Research examining the role of echo-chambers in facilitating extremist rhetoric within online incel communities is limited, despite real-world acts of violence perpetrated by self-proclaimed incels. Therefore, the objective of this thesis …

Crawling The Dark Web: Structural Attributes Of Child Sexual Abuse Websites On The Dark Web, Enrique Guerra

Master's Theses

Inherent encryption and anonymity of the Dark Web has facilitated its use for a variety of illegal activities, including the dissemination of child sexual abuse material (CSAM). Detection of CSAM has increasingly turned to automated tools; however, these tools’ reliance on databases of known CSAM limit their flexibility and ability to identify previously unknown CSAM. Currently, it is unknown whether the lack of countermeasures used by CSAM disseminators on the Surface Web translates to the Dark Web. Therefore, this thesis examines the structural and naming patterns of websites hosting CSAM on the Dark Web, to identify new, complimentary, detection methods. …

Linking Social Dynamics To Private Land Management: A Study Of Prescribed Burn Associations In Northern California, Spencer R. Klinefelter

Master's Theses

Prescribed fire is one way to improve the adaptive capacity of communities in the wildland urban interface in terms of managing wildfire risk and meeting socio-ecological goals. In California, Prescribed Burn Associations (PBAs) are a way of organizing private landowners with the goal of engaging in more widespread and frequent prescribed fires. This research uses semi-structured interviews with private landowners, along with key informants from public agencies such as CalFire and Regional Parks, to explore PBA development and functioning in northern coastal California. Sonoma and Marin counties were chosen as the primary study sites as they are represented by the …

Factors Impacting Indirect Potable Reuse Implementation In Orange County And Santa Clara County, Sarah E. Knott

Master's Theses

California is facing a water crisis that is impacting many of the state’s water sources such as groundwater basins, the Sacramento-San Joaquin Delta, and the Colorado River Basin. Therefore, it is important to conserve water using water reuse technologies such as indirect potable reuse (IPR) that can reduce the severity of intense, long-term water scarcity and serve as a drought-proof water supply. Developing more IPR projects throughout California could mitigate the state’s water issues, however, implementing IPR has been a challenge for many California water agencies. Most of the research on challenges to IPR implementation discusses public opposition as the …
