Diet Overlap And Competition Among Native And Non-Native Small-Bodied Fishes In The Colorado River, Grand Canyon, Arizona, Sarah Ellen Zahn Seegert

Master's Theses

Introductions of non-native fishes are threatening native fish communities in streams and rivers across the United States. The Colorado River especially has experienced numerous species invasions, and native fish populations throughout the basin are in decline. The native fish community in the Grand Canyon has been particularly affected, with half of the native fishes extirpated from the canyon. Many scientists blame interactions with non-native fishes for these declines. However, to date no one has conducted a thorough diet analysis of small-bodied fishes in the system to assess overlap between native and non-native fish diets. I analyzed the diets of native …

Functional And Phenotypical Analysis Of The Effects Of Aging On B Cells And Their Bone Marrow Microenvironment, Nicole May Ziegler

Master's Theses

Aging impacts multiple organ systems, and specifically causes the immune system to lose its ability to efficiently fight off infections. Regarding immunity, aging research predominantly focuses on the adaptive immune system. B cells, which mediate the humoral arm of the adaptive immune system, develop throughout life in the bone marrow where microenvironmental `niches' are important. The bone marrow does not exactly `atrophy' with age; however, studies comparing young and old mice demonstrate an age-related change in the bone marrow B cell subpopulations.

The overall goal was to determine if femoral and sternum bone marrow have different plasma cell composition and …

A Phonetic, Phonological, And Morphosyntactic Analysis Of The Mara Language, Michelle Arden

Master's Theses

Toward A Single-Consciousness: Challenging "Un-American-Ness" Of People Of Color, Bhawana Kamil

Master's Theses

Race is a major axis of social injustice in America. Social injustice is due to both maldistribution of material resources and opportunities and non-recognition or mis-recognition of people of color. One form of mis-recognition is the accusation that a person of color is not a real American, creating a conflict of identities (i.e., racial and American): a double-consciousness. This accusation has its origins in faulty ideas about race, identity, and race-group membership.

This paper presents a new model of identity that addresses these faulty ideas and provides a conceptual structure within which one can consistently maintain a single-consciousness while maintaining …

If I Could Choose: Internalized Homophobia Of The Queer Cinema Movement, James Joseph Flaherty

Master's Theses

This thesis offers a critical examination of essentialist and constructionist theories of queer identities, with emphasis on portrayals of internalized homophobia in film. The thesis examines three films released at the latter part of the first New Queer Cinema movement (1991 - 2000) - American Beauty (1999), Urbania (2000) and Velvet Goldmine (1998). Using criticisms of Queer as performativity, as theorized by Judith Butler, in addition to the works of Gregory M. Herek, Harry M. Benshoff, Jeffrey Weeks, and other theorists and academics, the thesis analyzes the use of characterization, mise-en-scene, and spatial and temporal relationships in these films as …

Who Am I?: The Reflexivity Of Self-Identity Through Tourism, Matthew Lee Milde

Master's Theses

This study has set forth to close gaps, explore innovative methods, and create a better understanding of "Who am I?", in tourism research. Few studies in tourism research focus on how experiences gained from traveling shape self-identity through personal biographies. Building on the work of seminal authors on self-identity, personal narrative, and tourism, this study explores the reflexivity of self-identity as represented in travel narratives. The lived experiences offered through narrative condition spontaneous instances of self-discovery allowing for the (re)creation of new self-identities.

Participants were selected through a snowball sample; in-depth interviews were held with fifteen (15) adults born and …

Two studies were conducted using a multi-method research approach in order to triangulate the results. Seven fatherless women were interviewed to arrive at a better understanding of how father absence informed their romantic relational experiences. Specifically, the topics of relationship roles, self-disclosure, expression, and self-silencing in romantic relationships were examined in the interviews. Participants reflected on what growing up fatherless meant to them and whether or not this had any influence on the role …

Visual Framing Of Patriotism And National Identity On The Covers Of Der Spiegel, Andrea Marie Pyka

Master's Theses

This thesis studied how Der Spiegel, a news magazine in Germany, visually framed images of German patriotism and national identity on its front covers between 1947 and 2009. This study specifically examined whether the covers showed an increase in symbols of patriotism and national identity following four major events in Germany. The events included: the building of the Berlin Wall, the reunification of Germany, the adoption of the Euro, and the 2006 World Cup. A framing analysis of the covers showed that there was an increase in symbols of national identity across each of these four events. However, based …

Improvement Of A Propagation Delay Model For Cmos Digital Logic Circuits, Rodger Lawrence Stamness

Master's Theses

Propagation delay models, for CMOS Digital Circuits, provide an initial design solution for Integrated Circuits. Resources, both monetary and manpower, constrain the design process, leading to the need for a more accurate entry point further along in the design cycle. By verifying an existing propagation delay method, and its resulting delay model, calibration for any given process technology can be achieved. Literature reviews and detailed analysis of each step in the model development allow for greater understanding of each contributing parameter, and ultimately, adjustments to the model calibration result in a more accurate analytical model. An existing model was verified …

Amount Of International News By Four World Newspapers: Pre And Post-9/11, Sidney Mitchell

Master's Theses

World newspapers, The New York Times, The London Times, The Australian, and The Toronto Star, have the power to enlighten countries and shape public opinion domestically and abroad. However, at times, newspapers tend to be biased and reflect ideologies or values, which tend to be slanted towards home cultures and personal politics. Consequently, the public often suffers because what it learns about the world may be distorted. As a result, newspapers have witnessed a steady decline in readership following the end of the Cold-War and continuing throughout post-9/11. Irrespectively, studies have reported “spikes“ in international news coverage following 9/11 that …

Ethnic Identity As A Moderator Of Ingroup Bias, Katherine Stokes-Guinan

Master's Theses

This thesis replicated and extended work by Perdue, Dovidio, Gurtman, and Tyler (1990) by priming 132 Asian, Hispanic, and White participants with ingroup and outgroup designators outside of conscious awareness before asking them to make judgments about positive and negative trait words. While bias patterns were similar for participants from all three ethnic groups, they were different among individuals with high and low scores on a measure of ethnic identity (the Multigroup Ethnic Identity Measure by Phinney, 1992). Specifically, participants with high ethnic identity scores demonstrated ingroup bias along ethnic lines, while participants with low ethnic identity scores did not. …

Does Nighttime Television Influence Attitudes Toward Drinking?, Mike Mchone

Master's Theses

Alcoholism is a problem in the United States. Television portrays individuals drinking alcohol. Is television influencing attitudes toward drinking? An experiment was performed with students from San Josè State University in the School of Journalism and Mass Communications to discover if television would indeed influence them to drink.

Two groups, both Mass Communication classes, participated in an initial survey, and then the test group class viewed a dramatized program in which the main character was depicted drinking glamorously. Both classes then took the same survey again. Results were analyzed via a t-test. Although there was a change in attitude regarding …

Numerical Simulation Of Capsule Dissolution In The Usp Apparatus Ii, Jasmine Han

Master's Theses

The capsule is the second most common type of drug dosage form, yet detailed research of capsule dissolution in the USP Apparatus II (a paddle dissolution apparatus that mimics the drug dissolution process in an in vivo environment) is not well reported. In this work, a mathematical model was developed that incorporates both the dissolution of the capsule shell and the slug within the capsule shell. Capsule shell dissolution was modeled with the assumption that the shell undergoes an erosion process only. The capsule slug dissolution model incorporated mass transfer principles, Markov chain theory, and the influence of hydrodynamics on …

Nutrient Removal By Algae Grown In Co2-Enriched Wastewater Over A Range Of Nitrogen-To-Phosphorus Ratios, Laura Michelle Fulton

Master's Theses

In conventional wastewater treatment, biological nutrient removal (BNR) depends on bacterial assimilation for phosphorus removal and nitrification+denitrification for nitrogen removal, with the resulting loss of the fixed nitrogen resource. Alternatively, treatment by microalgae allows for assimilative removal of both phosphorus (P) and nitrogen (N) thereby avoiding the oxygen demand of nitrification and preserving fixed N for fertilizer use. Paddle wheel mixed high-rate ponds have much higher algal productivity than typical oxidation ponds, but even high-rate ponds often cannot grow sufficient algae to completely assimilate the N and P in domestic wastewater. Algae growth in high-rate ponds is usually limited by …

The Effect Of Embryo Biopsy And Vitrification On The Development Potential Of Equine Embryos, Richard O. Gearhart

Master's Theses

This study investigated the development potential of equine embryos in vitro after biopsy and vitrification. Twenty embryos were obtained from Quarter Horse, Thoroughbred, and mix-breed light mares between three and ten years old. The twenty embryos were divided into a biopsy (n=10) and control group (n=10). The biopsy group underwent microaspiration biopsy using a micromanipulator to obtain a small tissue sample from the embryo. Both groups were then vitrified using a commercially available technique originally described by Carnevale (2006) at Colorado State \ University.

All 20 embryos were cultured in DMEM/Hams F-12 medium under oil at 37°C in 5% CO2 …

The Fundability And Marketability Of Green Buildings At Public Universities: Transcending The Funding Paradigm At Cal Poly, Eileen E. Joseph

Master's Theses

While in recent years Cal Poly has moved in the direction of sustainable building, my research indicates that where other CSU’s have succeeded, Cal Poly has been challenged in developing the type of green buildings that would truly make new construction projects more sustainable. The most commonly cited barriers are cost and lack of funding. The outcome however (as evidenced by other CSU’s) is not just driven by the state’s capital outlay process that has historically supported new construction on CSU campuses. It is determined by the priorities, perceptions and values that have influenced Cal Poly’s decision makers and driven …

The Effect Of All-Trans Retinoic Acid And Fatty Acids On Mcf-7 Breast Cancer Cell Progression, David A. Brown

Master's Theses

Vitamin A metabolites and retinoids may slow the progression of breast cancer and elicit anti-neoplastic properties similar to those of omega-3 fatty acids. Studies using animal models show a decrease in the incidence, growth and metastisis of mammary tumors in the presence of specific fatty acids. This effect is also seen with use of retinoids, specifically all-trans retinoic acid (AtRA). Thus, fatty acids may also alter retinoid homeostasis in mammary carcinoma cells (MCF-7s). The potential for inter/co dependency among fatty acids and retinoids is considerable, and here it has been hypothesized that a decrease in cancer progression will occur in …
