Exploring The Intersection Of Creative Practice Development And Second Language Acquisition In Adult Artists Professionally Connected To Seattle, Megan E. Deangelo

Master's Theses

Artists’ voices are disproportionately being excluded from international discourse because current English language education does not adequately serve this population of learners. This study was conducted as a catalyst for inquiry into the most effective ways artists acquire English so as to inform the development of curricula and programs to address their language learning needs. This study’s theoretical framework is created by Long’s (1981) interaction hypothesis and Skehan’s (1996) theory of task-based learning. The author proposes that artists’ English language learning experiences would be more fruitful if they were patterned after the interactions to which they are accustomed in their …

Combating Hiv/Aids In Marginalized Communities: Papua And West Papua Provinces, Indonesia, Bani Cheema

Master's Theses

My study focuses on foreign aid and local initiatives for HIV/AIDS prevention in eastern Indonesia using the provinces of Papua and West Papua as a case study. The two provinces are home to indigenous tribal groups that are socioeconomically marginalized and most affected by the epidemic. My research investigates behavior change communication as a principal strategy undertaken by multiple organizations for HIV/AIDS prevention in this region. I take a qualitative approach by examining the effectiveness of this strategy in local communities and by revealing social and cultural barriers that impede success. Obstacles that negatively impact prevention efforts include structural violence, …

Beyond The Economic: The Freedoms, Capabilities, And Social Capital Of Latin American Women Entrepreneurs In San Francisco, Melia M. Vilain

Master's Theses

In light of the scholarly debate surrounding the goals and mixed effects of development programs, particularly in recent years in relation to microfinance, this study investigates the effects of economic development programs on Latin American women entrepreneurs in San Francisco’s Mission District. It demonstrates that microfinance, when combined with education, can provide important non-economic benefits that contribute to increased freedoms and capabilities for immigrant women entrepreneurs. Drawing on qualitative interviews with ten business owners, as well as a review of the existing literature surrounding development, immigration, and gender, this research argues that owning a business in the US can produce …

Examining The Role Of Dax-1 In Regulation Of Cell Proliferation In Human Breast Cells, Amy E. Scandurra

Master's Theses

DAX-1 is a member of the Nuclear Hormone Receptor superfamily and acts as a transcriptional repressor. DAX-1 plays an important role in the development of adrenal and gonadal tissues. In addition to its role in normal cell development and differentiation, DAX-1 appears to have some influence on the progression of cancer. This work aims to examine the role of DAX-1 in regulation of proliferation in breast cancer. In our study, we have expressed DAX-1 in a DAX-1 deficient breast cancer cell line as well as knocked down DAX-1 expression in normal DAX-1 positive breast cells.

Migration, Global Middle Class, And Professional Development: How Chinese Graduate Students In The U.S. Re-Establish A Sense Of Selfhood, Sylvia Shi Pu

Master's Theses

Transnational migration inevitably leads to destabilization of identity. Groups with different characteristics adopt varied strategies to restabilize a sense of selfhood. Elite global migrants, well-equipped with economic, cultural, and educational capital, tend to embrace a cosmopolitan lifestyle in the new location (Favell 2008). In contrast, migrant workers with limited human capital depend on their national peers for useful information and resources in order to make smooth transition across borders (Brown 2011). However, the case of the elite Chinese student migrants fits into neither of the trajectories. In regaining a sense of personhood, those global middle-class migrants end up in a …

Relative Expression Of Germination Genes Sleb, Gerac, And Gpr In Heat Treated Bacillus Licheniformis And Bacillus Subtilis, Valerie Paige Arechiga

Master's Theses

Endospore-forming bacteria of the genus Bacillus are of significant importance to the food industry. Species from this genus exhibit the ability to form metabolically dormant endospores characterized by resistance to heat, UV, and chemical treatment. Spores have undetectable metabolic activity and remain impervious to the harsh conditions of their environment, but they can detect environmental cues signaling favorable growth conditions and begin the process of germination. Once germination and outgrowth are complete, the fully viable cell is capable of reproducing and forming colonies. The resistance of these endospores has been a topic of decades of research, particularly because of their …

A Case Study On The Apple Hill Grower's Association: An Agritourism Area In Camino, Ca, Christine J. Delfino

The Effect Of Artery Bifurcation Angles On Fluid Flow And Wall Shear Stress In The Middle Cerebral Artery, Zachary Ramey Jones

Master's Theses

Saccular aneurysms are the abnormal plastic deformation of veins and arteries that can lead to lethal thrombus genesis or internal hemorrhaging. Medication and surgery greatly reduce the mortality rates, but treatment is limited by predicting who will develop aneurysms. A common location for saccular aneurysm genesis is at the main middle cerebral artery (MCA) bifurcation. The main MCA bifurcation is comprised of the M1 MCA segment, parent artery, and two M2 segments, daughter arteries. Studies have found that the lateral angle (LA) ratio of the MCA bifurcation is correlated with aneurysm formation. The LA ratio is defined as the angle …

A Novel Dual Modeling Method For Characterizing Human Nerve Fiber Activation, Frank Daniel Sugden

Master's Theses

Presented in this work is the investigation and successful illustration of a coupled model of the human nerve fiber. SPICE netlist code was utilized to describe the electrical properties of the human nervous membrane in tandem with COMSOL Multiphysics, a finite element analysis software tool. The initial research concentrated on the utilization of the Hodgkin-Huxley electrical circuit representation of the nerve fiber membrane. Further development of the project identified the need for a linear circuit model that more closely resembled the McNeal linearization model augmented by the work of Szlavik which better facilitated the coupling of both SPICE and COMSOL …

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Protective Effects Of Milk Phospholipids Against Uv-Induced Dna Damage In Human Skin Cells, Lan-Anh Nguyen

Master's Theses

Skin cancer is the most common type of cancer in the US. The American Academy of Dermatology estimated that more than 3.5 million new cases of skin cancer are diagnosed in the US each year and 1 in 5 Americans will likely to develop skin cancer in their life time. Most cases of skin cancer are caused by exposure to ultraviolet (UV) radiation from the sun. Some of the most common sunscreen ingredients are unstable and can form harmful radicals upon exposure to UV radiation. There is a strong clinical need for a more stable and effective sunscreen ingredient such …

A single use pharmaceutical mixer was analyzed for performance with various system configurations using Computational Fluid Dynamics. The analysis was conducted across a range of oscillation frequencies and liquid fill levels within a fully sealed mixing tank to determine the rate of fluid homogenization, liquid shear, velocity profiles and force application utilizing a single and dual mixer flat plate head configuration. These characteristics are useful for predicting the expected mixing time of a fluid and how much fluid shear is acting on protein cultures that are intended to be grown in the mixing vessel. General trends show that larger fill …

Growth Media And Lipid Determination Comparison Of High Rate Algae Ponds, Eric Alexander Nicolai

Master's Theses

Growth Media and Lipid Determination Comparison

of High Rate Algae Ponds

Eric Alexander Nicolai

The feasibility of algal biofuel production relies on the use of a non-potable water source. Municipal wastewater is nutrient-rich and a cost effective option as a growth media in algae ponds. However, this resource may be too valuable for algal biomass production, as reclaimed wastewater is needed for surface irrigation and groundwater recharge. This thesis compares the performance of 4.2 m² high rate algal raceway ponds (HRAPs) to 33 m² HRAPs grown on primary settled wastewater during a media recycling study and a growth …

You're A Good Man, Charlie Brown: An Analysis Of Compassion, Friendship, And Overcoming Obstacles, Jessamyn L. Miller

Master's Theses

Since the late 1960s many things have changed. With the inception of the Internet, much of the world has gone viral––including newspapers. Children rarely find the same joy their parents found in a nostalgic printed Sunday morning comic strip. In addition, societal tragedies have increased with almost daily occurrences highlighted on the news. With an influx of recent tragedies too close to home, this thesis examines arts advocacy facts, anti-bulling campaigns, and the themes of friendship, compassion, and overcoming obstacles within a production of Clark M. Gesner’s musical You’re a Good Man, Charlie Brown [Revised]. Charles M. Schulz’s classic characters …

The Abc's Of Being A Fan: An Operant Analysis Of Sports Consumption Behavior, Sean Pradhan

Master's Theses

In the last 30 years, behavioral psychologists have begun to systematically apply the principles of operant theory to the analysis of consumer behavior. Two behavioral approaches that have been successfully employed in consumer behavior analysis are the Behavioral Perspective Model (BPM; Foxall, 1990) and the Behavioral Ecology of Consumption (BEC; Rajala & Hantula, 2000). However, neither of these models has been used to analyze sports consumption behavior. One purpose of the present study was to integrate consumer behavior models with other theoretical approaches to the investigation of sports consumption behavior. A second purpose was to examine the effects of three …

Intentional Weight Loss Among Healthy Women: Behavior Patterns And Psychological Concerns, Kelsea Marie Ryan

Master's Theses

Although there is an extensive literature on women who are overweight, obese, or suffer from eating disorders, less is known about women who are at a healthy weight yet who are attempting to lose weight. To learn more about the psychological characteristics and behavioral patterns of such women, this study analyzed data from the American College Health Association's National College Health Assessment (ACHA-NCHA-II). We compared these women with two groups of women: (a) those who are at a healthy weight but who are not attempting to lose weight and (b) overweight women who are attempting to lose weight. We employed …

Exploring The Glucocorticoid Actions Of 1Α-Hydroxycorticosterone (1Α-Oh-B) In The Elasmobranch Fishes, Faith Nichole Lambert

Master's Theses

The corticosteroid 1α-hydroxycorticosterone (1α-OH-B) is unique to the elasmobranch fishes. It is thought that 1α-OH-B acts as both the primary glucocorticoid (GC) and mineralocorticoid (MC) in these fishes, a dual role analogous to that of cortisol in the teleost fishes. The MC characteristics of 1α-OH-B are well supported, but data supporting its GC functions are lacking. In this study, the putative GC actions of 1α-OH-B were examined. The first experiment characterized the physiological stress response of the Atlantic stingray (Dasyatis sabina) to air exposure, with particular regards to the roles of corticosteroids and metabolic fuels. Results demonstrate that …

The Drosophila T-Box Transcription Factor Midline Functions Within The Insulin/Akt And C-Jun-N-Terminal Kinase Signaling Pathways To Regulate Interomatidial Bristle Formation And Cell Survival, Qichuan Chen

Master's Theses

From a genetic and allelic modifier screen, we report that the Drosophila melanogaster T-box transcription factor midline (mid), a homolog to the human TBX20 gene, interacts with dFOXO within the insulin receptor (InR) and the c-Jun-N-terminal kinase (JNK) signaling pathways to regulate interommatidial bristle (IOB) formation. Previous studies have identified mid’s role in cell fate specification of sensory organ precursor cells in conjunction with the Notch-Delta signaling pathway (Das et al., 2013). The Notch, InR, and JNK signaling pathways regulate dFOXO activity under conditions of stress. Thus, we determined the effects of oxidative stress and metabolic stress by …

Participatory Democracy In The Chinese Cyber World: Case Studies From Weibo, Duyi Li

Master's Theses

This thesis discusses features of citizen communication on Weibo, the Chinese social media platform, and its relationship to participatory democracy in China. Weibo is a complex social space due to the interplay of different forces and social actors. On the one hand, Weibo provides the space for bottom-up political participation: it expands the horizontal discursive space where plural discourses coexist and interact; provides a social sphere where counter-discourses are created; a space where the culture of resistance is formed; and serves as an alternative source for information. On the other hand, the vertical political control of the state, and the …

Lynn Hershman Leeson's Roberta Breitmore And The Art Of Becoming A Woman, Maayan Glaser-Koren

Master's Theses

Throughout the emergence of second-wave feminism in the 1970s, social and political activism inspired female artists to create powerful artworks that critiqued institutional discrimination and supported women's reproductive rights and workplace equality. Feminist artists raised the public's awareness of women's issues by making women the subject of their artwork. In California especially, these creators turned to performance art, often taking their creations to the streets.

This thesis focuses on Lynn Hershman Leeson's performance, Roberta Breitmore (1974-1978), and examines how, through the steps of the performance, the piece's fictitious title character became a living resident of San Francisco. It will explore …

The Effect Of Cyclophilin A On Vaccinia Virus Replication In Vitro, Kathryn Korhonen

Master's Theses

The host protein cyclophilin A (CypA) has been shown to be necessary for viral replication of several viruses, including human immunodeficiency virus and hepatitis C virus. Previous research done in the Geary laboratory, in collaboration with Pacific Northwest National Laboratory, reported that cyclophilin A remains highly associated with vaccinia virus virions even after successive rounds of purification. The goal of this research is to further investigate how cyclophilin A affects vaccinia virus replication in vitro using primary tissues harvested from CypA (-/-) knockout mice to determine the difference in viral growth kinetics. Results showed different viral growth kinetics in …

The Influence Of Workaholism On Work-Life Issues Through Boundary Management: Moderating Effects Of Telecommuting, Anna K. Young

Master's Theses

There are many personality and contextual variables that can contribute to negative home-domain functioning. The current study examined the effect of two specific variables, workaholism and telecommuting, on work-life issues. A moderated mediation model was tested, in which boundary flexibility mediated the relationship between workaholism and telecommuting and work-to-family conflict and family disengagement. Additionally, telecommuting was tested as a moderator of the indirect effect of workaholism on work-life issues through boundary flexibility willingness. I recruited 494 full-time, salaried, working adults through Amazon’s Mechanical Turk. Though there were many significant direct effects, the data only suggested partial support for the indirect …
