1300 Years Of Snowpack Change For The Sangre De Cristo Mountian Range, Michael Thornton

Master's Theses

New Mexico is heavily dependent on hydrologic inputs along high elevation sites where much of the cool-season precipitation accumulates as snowpack in the lower Southern Rocky Mountains. Snowpack runoff from the Sangre de Cristo (SDC) range provides critical headwater resources for the two major rivers that run through New Mexico and by extension the greater population. Yet, over the past four decades snowpack data from high and mid-elevation sites exhibit a linear trend of declining snowpack in conjunction with earlier seasonal melting. Due to the importance of these cool-season inputs for the region, a decline in montane runoff availability is …

Interplay Of Dgat1, Pdat1 And Dgat2 Enzymes In Plant Triacylglycerol Assembly, Anushobha Regmi

Master's Theses

Acyl-CoA:diacylglycerol acyltransferase (DGAT) catalyzes the transesterification of fatty acid from acyl-CoA to diacylglycerol (DAG) forming triacylglycerol (TAG, a.k.a oils and fats). Most plants have at least two unrelated DGAT genes, DGAT1 and DGAT2. Plants predominantly express only one during oil synthesis; the reason, however is not clear. A few studies have indicated that each enzyme prefers DAG and acyl-CoA substrates with different fatty acid compositions. Industrially desirable seed oil composition can be obtained through genetic engineering by replacing the endogenous enzyme with one that has different substrate selectivity. In Arabidopsis thaliana, DGAT1 and another unrelated enzyme PDAT1 are essential …

A Meat Paradox: Media's Role In Mitigating The Omnivore's Dilemma, Karyn Camille Lewis

Master's Theses

The purpose of this research is to identify and understand media’s role in meat consumption and a disassociation of meat and its animal of origin. This study questions consumer behavior based on media portrayals of meat products as well as how consumers perceive these portrayals, meat consumption patterns based on media and family influence, and the types and levels of satisfaction (ex: self-esteem or masculinity) consumers receive from meat products.

A quantitative research approach was proposed for this study. The primary research method was a survey among students, faculty and staff at The University of Southern Mississippi. A total of …

"There Was Something Grotesque": The Application And Limits Of Respectability In The Daughters Of Bilitis, Elizabeth Diane Greer

Master's Theses

Living in both the “deviant” and “normal” worlds, the leadership of The Daughters of Bilitis generally adhered to a respectable and assimilationist public persona as evidenced through political activities and the publication of their periodical The Ladder. Due to this juxtaposition, the largely middle-class, white membership exhibited socially conservative views in order to make long-term social change, leading to an inherent contradiction between maintaining their middle-class identity and public respectability. Seen from the organization’s founding in 1955 until its collapse in 1970, these contradictions and the focus on respectability politics adds to the existing scholarship on the DOB.

The …

Linkages Between Marsh Fragmentation, Prey Availability, And Blue Crab (Callinectes Sapidus) Abundance And Mortality, Lennah Shakeri

Master's Theses

Coastal marshes are important nursery habitats for many commercially important invertebrate species, yet these marshes are being lost worldwide at an unprecedented rate due to subsidence, erosion, climate change, and human activity. As marsh is lost, it creates the opportunity for submerged aquatic vegetation (SAV) colonization and establishment in newly created open water areas. Blue crabs, Callinectes sapidus, use both marsh edge and SAV habitat during the juvenile stages and support one of the largest fisheries in the Gulf of Mexico, worth over $70 million in 2015. This thesis studied the linkages between habitat type, SAV cover, benthic prey …

Behavioral Skills Training To Teach Correct Heading Skills To Youth Soccer Players, Laura Quintero

Master's Theses

Recently, concerns regarding sport-related concussions have increased within the research literature, the media, and popular culture. It is unknown to what degree purposefully striking the ball with one’s head (i.e. heading) contributes to concussions within youth soccer. There is currently limited research on an effective teaching method to improve heading technique. Due to the numerous applications of Behavioral Skills Training (BST) to teach a wide variety of behaviors, the purpose of the current study was to evaluate the effectiveness of BST to teach correct heading techniques to youth soccer players. A task analysis was produced to score each header. Results …

An Empirical Study Of Css Code Smells In Web Frameworks, Tobias Paul Bleisch

Master's Theses

Cascading Style Sheets (CSS) has become essential to front-end web development for the specification of style. But despite its simple syntax and the theoretical advantages attained through the separation of style from content and behavior, CSS authoring today is regarded as a complex task. As a result, developers are increasingly turning to CSS preprocessor languages and web frameworks to aid in development. However, previous studies show that even highly popular websites which are known to be developed with web frameworks contain CSS code smells such as duplicated rules and hard-coded values. Such code smells have the potential to cause adverse …

The Impacts Of Sex And Myogenic Cell Transplantation On Collateral Capillary Arteriogenesis, Padon Mary Sivesind

Master's Theses

Current treatments for peripheral arterial occlusive disease (PAOD) have limited success, so there is a need to develop more effective treatments. Because patients with native collaterals have a better prognosis, promoting collateral arteriogenesis is a potential PAOD treatment. Additionally, female PAOD patients have a worse response to treatment and a worse prognosis compared to males, which could be due to impaired collateralization. Cell transplantation is a potential treatment option to promote collateral arteriogenesis. Bone marrow derived stem cells are the main cell type that has been investigated, but they have had limited clinical success. Delivering a stem cell type native …

Mobile Security Education With Android Labs, Siavash Rezaie

Master's Theses

The recent consumer explosion of smartphones and tablets has led to the proliferation of sensitive data stored on mobile devices and the cloud. In 2015, it was reported that 16.2% of files uploaded to file sharing services contain sensitive data (Skyhigh Networks). With users having so much personal data on their devices and the cloud, security becomes an imperative subject. Unfortunately, security is often overlooked or implemented improperly in many commercial devices. Knowledge of security fundamentals is essential to ensure users maintain their privacy and security.

The work in this thesis designs and implements five labs for a potential undergraduate …

Characterization Of Botrytis Cinerea Resistance To Fungicides In California Strawberry Production, Scott D. Cosseboom

Master's Theses

Gray mold of strawberry, caused by Botrytis cinerea, is a very destructive pre- and post-harvest fruit rot. Outside of California, fungicide resistance in B. cinerea has been reported to every site-specific chemical class labeled for use against gray mold. One objective of this study was to characterize the resistance of 888 isolates of B. cinerea from California strawberry fields to ten active ingredients. Isolates were collected from the same planting block in 47 fields during the early-season (0 to 8 fungicide applications) and late-season (16 to 26 fungicide applications) of 2016. Sensitivity of each isolate was determined using the …

Predicting The Vote Using Legislative Speech, Aditya Budhwar

Master's Theses

As most dedicated observers of voting bodies like the U.S. Supreme Court can attest, it is possible to guess vote outcomes based on statements made during deliberations or questioning by the voting members. In most forms of representative democracy, citizens can actively petition or lobby their representatives, and that often means understanding their intentions to vote for or against an issue of interest. In some U.S. state legislators, professional lobby groups and dedicated press members are highly informed and engaged, but the process is basically closed to ordinary citizens because they do not have enough background and familiarity with the …

Showing Programmers That They Already Know How To Write Well, Alanna Buss

Master's Theses

Being able to communicate effectively through writing is an important skill for computer scientists and software engineers. In addition to being able to write code, programmers need to write clearly and concisely for everything from comments in their code to documentation. Despite writing being essential to their future careers, many programming students from Cal Poly find writing to be unimportant and many of them believe that they are not capable of writing good papers. How can Cal Poly help these students?

This paper describes a pedagogy to help students improve their writing skills. It is based heavily on the belief …

Nanoscale Mapping Of In-Situ Micro Electro Mechanical Systems With Atomic Force Microscopy, Manuel Rivas

Master's Theses

Micro-electro-mechanical-systems (MEMS) are increasingly at our fingertips. To understand and thereby improve their performance, especially given their ever-decreasing sizes, it is crucial to measure their functionality in-situ. Atomic Force Microscopy (AFM) is well suited for such studies, allowing nanoscale lateral and vertical resolution of static displacements, as well as mapping of the dynamic response of these physically actuating microsystems. In this work, the vibration of a tuning fork based viscosity sensor is mapped and compared to model experiments in air, liquid, and a curing collagen gel. The switching response of a MEMS switch with nanosecond time-scale activation is also monitored …

Characterizing The Roles Of Staphylococcus Aureus Secreted Factors In Virulence And Modulation Of Innate Immune Cell Activity, Cameron Harvey

Master's Theses

Staphylococcus aureus is a prominent human pathogen that is responsible for a massive burden on healthcare. This thesis takes two approaches to characterize how S. aureus secreted factors subvert the innate immune response. First, characterization of the integral membrane protease 1984 showed that it regulates secretion of a putative lytic transglycosylase, IsaA, which is implicated in virulence. My results suggest IsaA and 1984 are capable of modulating immune responses that result in enhanced heart colonization in vivo. In addition, recent studies have uncovered TLR-independent pathways that induce inflammatory responses after S. aureus insult. Therefore, I hypothesized the bacterium secretes factors …

Consistency Of Health Behaviors And Relations To Bmi In First Year College Students, Laura Nicholson

Master's Theses

Existing research suggests that individuals with erratic schedules (e.g., shift workers) may be at greater risk for weight gain. This may be due, in part, to the inconsistent timing of health behaviors, such as sleep. Little is known, however about the relevance of the consistent timing of health behaviors among other populations, including college students who are risk for weight gain. The current study examined the consistency of three health behaviors (i.e. sleep, eating occurrences, and physical activity) and relations with body weight among first year college students at a large Midwestern university. Daily diary methods were used to collect …

It's About Time: Length Of Incarceration, Gang Membership, And Recidivism Among Illinois Prison Releasees, Henry Douglas Otto

Master's Theses

This study explored the effect of time spent incarcerated on recidivism among a sample of individuals released from IDOC facilities from 2011 to 2014 (N = 72,716). Gang members were compared to non-gang members in order to evaluate the potentially heterogeneous nature of the effect of length of stay on recidivism within the competing frameworks of deterrence theory and social learning theory. The samples were further split into separate analyses based on the current felony class, and length of stay was operationalized as incarceration in months and split into quartiles based on the distribution of each felony class sample. The …

Analysis Of Fiber Network Architecture In Blood Vessels And Blood Clots, Dustin Michael Nguyen

Master's Theses

Fibrous networks, including collagen and fibrin, provide strength and support, and are critical for maintaining homeostasis. In this study, we have developed algorithms to define the structural properties of collagen and fibrin networks from microscopic images of these networks in abdominal aortic aneurysms (AAA) and blood clots, respectively. AAA is a biomechanical disease characterized by significant changes in the structure and strength of the arterial wall due to differential changes in the composition of fibrillar collagen in adventitial and medial layers. Using bright-field and polarized microscopic images of histological sections of mouse aorta stained with Picrosirius red (PSR) stain, we …

Separation Events In Modern Greek, Vasiliki Lydia Rounti

Master's Theses

The semantic domain of separation events has been studied for a number of languages. In this thesis, a study on how Modern Greek expresses separation events and how semantically distinct they are from other languages is presented. This is the first study on the semantic features of separation events for Modern Greek. Furthermore, it is the only study so far on separation events for which data have been gathered from a large number of native speakers. Thus, this thesis not only offers a great insight on the language’s semantic structures, but it also presents more concrete observations and conclusions compared …

Examining Outcomes And Mechanisms Of The Honest, Open, Proud Intervention In College Students With Mental Illness, Carol Hundert

Master's Theses

Emerging adulthood is a developmental stage involving many changes and transitions (Arnett, 2004). The instability during this time can cause significant distress, making this a period of increased vulnerability for the development of mental illness (Kessler et al., 2007). The rise in the incidence of mental illness on college campuses has caused an increased demand for mental health services (Kadison & Digeronimo, 2004). Unfortunately, college students face many barriers to treatment, including self-stigma (Eisenberg, et al. 2009). Honest, Open, Proud for college students (HOP-C) is a peer-led group-based intervention designed to reduce self- stigma in college students living with mental …

Resiliency, Bajo Que Costó? How Young Undocumented Mexicans Navigate Trauma And Survival, Julia Mendes

Master's Theses

Under the Trump administration, Deferred Action for Childhood Arrivals (DACA) has become a "hot topic" in political discourse and in the media. Amidst this discourse, however, the stories of DACA recipients whose lives are drastically affected by this political drama are often overlooked. Furthermore, a problematic narrative has emerged labeling the "dreamers" as "good immigrants" who need to be saved at the expense of their families, relatives, and other undocumented immigrants who do not fit into the "dreamer" category. Another problematic aspect of current research is celebrating this aspect of "resiliency" that undocumented youth portray and ignoring the consequences this …

Never Silent: Evolution Of Black Women's Anti-Rape Organizing, 1965 - 1985, Keisa Rochelle Reynolds

Master's Theses

Black women experience multiple oppressions due to their gender and their race, and those oppressions are expounded when other social identities, such as class and sexual orientation, are considered. There have been many instances in history of social movements in which black women have fought against the many issues they face. For the purpose of this project, I am looking specifically at 1965 - 1985 to examine the ways in which black women organized against white supremacy and sexual violence. The two forms of oppression would have led black women activists into different organizations for black liberation and women's liberation-- …

A Sociofunctional Approach To Understanding Transphobia, Linas Mitchell

Master's Theses

Despite widespread evidence of anti-transgender prejudice and discrimination, research has yet to determine the nature of prejudice against transgender people. This study used the sociofunctional threat approach (Cottrell & Neuberg, 2005) to examine threat perceptions (contamination threats, obstacle threats, physical safety threats, and threats to reciprocity relations) and emotional reactions (disgust, anger, fear, pity) to transgender (transgender women, transgender men, and nonbinary people) and cisgender (cisgender women, cisgender men, and bisexual people) targets. Results from an online survey suggest that transgender targets evoke higher threat perceptions and negative emotions than cisgender targets; additionally, this tended to be the case for …

Queer People Navigating Experiences With Health Care Providers And Contraception, Dana Lavergne

Master's Theses

Contemporary views of contraception have intrinsically linked birth control to heterosexual sex and pregnancy prevention. As such, contraception is culturally understood to be exclusively for heterosexual women. Despite this, the little work that has been done on queer people1 and contraception use demonstrates they are also accessing birth control (Chrisler, Gorman, Manion, Murgo, Adams-Clark, Newton and McGrath 2015). This schism between the cultural understanding of contraception as a manifestation of heterosexual womanhood and the everyday use of contraception by both queer and heterosexual people takes root in the medical system. Based in heteronormative ideologies, the medical system fails to take …

Immunobiology Of Adenovirus-Vector Vaccines For Mrsa, Emily Orvis

Master's Theses

Staphylococcus aureus is a gram-positive, extracellular bacterium that has emerged as an

important human pathogen. This bacterium is a leading cause of skin and soft tissue infections

(SSTIs) in humans, often leading to invasive and life-threatening infections. Treatment of S.

aureus infections is becoming more complicated due to the rise of methicillin-resistant S. aureus

(MRSA) strains, which are becoming increasingly resistant to a number of antibiotics. In the

United States, invasive MRSA infections result in more deaths annually than any other infectious

agent.

Despite a dire need, there is currently no vaccine against S. aureus infections. The failure

of past …

Union Busted: Understanding The Relationship Between Democrats, Republicans, And Teachers’ Unions, Roman Motley

Master's Theses

There is an almost symbiotic relationship between the Democratic Party and labor unions. Labor unions emerged as the largest donors and staunchest organizers for Democrats. This is all especially true for teachers’ unions. The American Federation of Teachers and the National Education Association represent the largest organizational donors to the Democratic Party. Democrats on the national stage compete fiercely for these two organization’s endorsement. So, if teachers’ unions represent such an important donor and organizing base for Democrats how can we explain Democratic politics on education? Race to the Top was highly unpopular with unions and supported by Democrats. Liberal …
