Temporal And Spatial Impacts Of Water Control Structures On The Benthic Infaunal Community Of A Tidally Restricted Wetland In Elkhorn Slough, Ca, Christine Marie Mann

Master's Theses

North Azevedo Pond in Elkhorn Slough, CA is a partially tidally restricted wetland that underwent an experimental ponding manipulation which increased inundation and tidal mixing within the system. This wetland has two spatially significant infaunal microsystems, south and north. Benthic cores taken before and after the manipulation showed that both the south and north infaunal communities remained dominated by the same major taxa, respectively. Both systems, however, experienced species shifts following the ponding manipulation. In the South, the non-native bivalve, Gemma gemma, declined from an average of 19,103 to 385 individuals (m2)-1 whereas the native clam, Nutricola tantilla, increased from …

Latino Representation On Primetime Television In English And Spanish Media: A Framing Analysis, Gabriela Arellano

Master's Theses

The purpose of this study was to provide updated data on the Latino portrayals on primetime English and Spanish-language television. Three major contributions of this study are baseline data on the percentage of white actors as well as all racial and ethnic minorities on English-language television, the portrayal of Latinos on both English and Spanish-language television, and the development of five frames that measure the representation of Latino characters. The results of this framing study showed that only 7.4% of the characters in primetime TV on ABC and CBS were Latino. Although the Latino representation in primetime American television was …

The Relationship Between Perceptions And Actual Use Of Workplace Flexibility And Employee Engagement, Katherine Baer

Master's Theses

Previous research has identified both perceptions of the availability of flexible work arrangements and use of these arrangements as a predictor of engagement (Richman, Civian, Shannon, Hill, & Brennan, 2008; Ten Brummelhuis, Bakker, Hetland, & Keulemans, 2012). However, no studies have looked at the incremental effect use of flexible work arrangements have on engagement, above and beyond actual use. Very few studies have looked at how gender moderates the relationship between perceptions of flexible work arrangements and use of flexible work arrangements and engagement. The purpose of this study was to examine and compare the relationships between perceptions and actual …

Convolutional Neural Network Acceleration On Gpu By Exploiting Data Reuse, Sindhuja Gopalakrishnan Elango

Master's Theses

Graphical processing units (GPUs) achieve high throughput with hundreds of cores for concurrent execution and a large register file for storing the context of thousands of threads. Deep learning algorithms have recently gained popularity for their capability for solving complex problems without programmer intervention. Deep learning algorithms operate with a massive amount of input data that causes high memory access overhead. In the convolutional layer of the deep learning network, there exists a unique pattern of data access and reuse, which is not effectively utilized by the GPU architecture. These abundant redundant memory accesses lead to a significant power and …

The Moderating Effect Of Gender And Tenure On The Relationship Between Perceived Supervisor Support And Organizational Commitment, Megan Evelyn Little

Master's Theses

The purpose of this study was to explore the extent to which the demographic variables of gender and tenure influence the strength and direction of the relationship between perceived supervisor support and organizational commitment. Responses to a 2014 organization-wide employee opinion survey from 383 employees within a computer software company were analyzed using hierarchical multiple regression. In support of previous research, results from this study lay credence to the finding that perceived supervisor support has a positive, significant relationship with organizational commitment such that individuals who felt supported by their supervisors were more likely to report higher levels of organizational …

In Colbert We Trust: Teenagers And Comedic Persuasion, Peter G. Kistler

Master's Theses

In this study, high school students were exposed to either a comedy or conventional television news editorial segment, and each video’s persuasive effect was compared with the other. The sample consisted of 271 high school students from Valley Christian High School in San Jose, CA, a majority of whom were juniors and seniors. Students were separated into sample groups; one group viewed a Colbert Report editorial and guest interview focused on the concept of net neutrality, while the other group viewed an All In with Chris Hayes editorial and guest interview focused on the same subject. Both sample groups were …

The Moderating Role Of Transformational Leadership And Perceived Organizational Support In The Relationship Between Openness To Experience And Creativity, Monica Luu

Master's Theses

Although openness to experience has been found to be a consistent and important determinant of creativity, organizations have been interested in ways in which they could alter the environment in order to increase creativity. Woodman, Sawyer, and Griffin (1993) argue that organizational creativity is a function of the interaction between an individual’s personality and environment. Using Woodman’s theory, the present study was conducted to test whether two organizational factors, transformational leadership and perceived organizational support (POS), would moderate the relationship between openness to experience and creativity. Data were collected from 114 fulltime and parttime employees from various organizations through use …

Recombinant Expression And Potential Autocatalysis Of Aedes Aegypti Trypsin-Like Serine Proteases (Aaspii And Aaspiv), Diane Francine Eilerts

Master's Theses

Aedes aegypti mosquitoes can be found globally in tropical and subtropical urban areas and spread Zika, Dengue fever, yellow fever, and Chikungunya viruses. Current vector control methods are limited and nonspecific. The female Ae. aegypti mosquito uses blood meal proteins to obtain nutrients required for oogenesis; inhibition of the midgut trypsin-like serine proteases responsible for blood meal digestion may provide a novel method of vector control. Ae. aegypti blood meal digestion is complex and the role of uncharacterized serine proteases in blood digestion is unclear; specifically, a group of trypsin-like serine proteases (AaSPII–V) is expressed at constant levels before and …

Using Stable Isotope Analysis To Infer Breeding Latitude And Migratory Timing Of Juvenile Pacific-Slope Flycatchers (Empidonax Difficilis), Emily Bailey Moffitt

Master's Theses

Effective conservation of migratory species is hindered by a lack of knowledge of population links between breeding, wintering and stopover habitats. The Pacific-slope flycatcher (Empidonax difficilis) is one of the many Neotropical migratory songbirds whose populations are steadily declining throughout western North America. This research contributed to the assessment of connectivity in this species by inferring relative breeding origins and habitat selection of juvenile birds that migrate along the Pacific Flyway to the South San Francisco Bay Area in the fall. Feather data collected from July 20 to October 12, 2014 were analyzed for three stable isotopes (δ2H, δ13C, δ15N). …

Intelligent Threat-Aware Response System In Software-Defined Networks, Kunal Ketan Goswami

Master's Theses

Software-defined networks decouple the control plane from the data plane, enabling researchers to evaluate protocols and network configurations through the centralized point of control, the controller. They provide easy management and automation, scalability, and flexibility in the traditional computer network. In spite of these advantages, software-defined networks fall prey to various denial-of-service attacks specific to network protocols and applications despite their simplicity. There is a need to implement intelligence in the controller as a countermeasure for not only the various types of denial-of-service attacks but also the increasing sophistication involved in them. In this paper, an intelligent threat-aware response system …

A Taxonomic Revision Of Eastern North Pacific Softnose Skates (Arhynchobatidae: Bathyraja Ishiyama), James Desmond Stanley Knuckey

Master's Theses

Softnose skates (Rajiformes: Arhynchobatidae: Bathyraja Ishiyama) are the most diverse genus of skates, with 54 described species, and are readily distinguishable from their congeners by their relatively uncalcified and flexible rostral cartilages. Six species of Bathyraja are considered valid in the eastern North Pacific, including: deepsea skate, B. abyssicola, Aleutian skate, B. aleutica, sandpaper skate, B. kincaidii, fine-spined skate, B. microtrachys, Pacific white skate, B. spinosissima, and roughtail skate, B. trachura. As with other skate genera, the eastern North Pacific Bathyraja lacks a well-supported phylogeny, which leads to issues with setting catch limits and creating management plans. This study identifies …

Devil In A White Dress: Marie-Antoinette And The Fashioning Of A Scandal, Sarah Lorraine Goodman

Master's Theses

The portrait of Marie-Antoinette by Elisabeth Vigée-Lebrun, known as La Reine en gaulle, has been discussed widely in art history owing to the scandal it provoked when it was exhibited in the Paris Salon in August 1783. Analysis has focused primarily on socio-economic issues of late-ancien regime France as a means of understanding how a relatively benign portrait of the Queen of France could engender so much anger when displayed for public consumption, centering around the queen’s identity as a public figure in contrast to the private individual painted by Vigée-Lebrun. However, very little has been discussed about the clothing …

Structural Analysis Of Eocene Dike Swarms In And Near The Duncan Hill Pluton, North Cascades, Washington, Kathleen Bryant

Master's Theses

Voluminous Eocene dikes in the North Cascades are thought to provide insights into the regional strain field during postulated ridge–trench interaction in the Pacific Northwest. One understudied area with a large number of dikes is spatially associated with the elongate (NW-SE), ~46 Ma granodioritic Duncan Hill pluton. The ~80 km2 study area contains the shallow part of this pluton and the host schist of the Twentyfive Mile Creek unit and tonalite and migmatite of the Cretaceous Chelan Complex. Field observations and petrographic analyses indicate that the dikes in the study area can be sub-divided compositionally and texturally into three types: …

Biochemical And Enzymatic Studies Of The Midgut Serine Protease Aaspvii From The Aedes Aegypti Mosquito, James Thientoan Nguyen

Master's Theses

The Aedes aegpyti mosquito is an efficient biological vector of four known neglected tropical arboviruses: the yellow fever, dengue, chikungunya, and Zika viruses. Since the female mosquito can acquire multiple blood meals to complete the gonotrophic cycle, she can potentially infect multiple hosts. With the reemergence of these viruses, especially due to global warming, it is crucial to slow the spread of the mosquito and the blood-borne diseases she transmits. The Ae. aegypti mosquito relies heavily on midgut serine proteases that digest blood meal proteins to provide nutrients required for the egg laying process. The focus of this work is …

Network Traffic Anomaly-Detection Framework Using Gpus, Meera Ramesh

Master's Theses

Network security has been very crucial for the software industry. Deep packet inspection (DPI) is one of the widely used approaches in enforcing network security. Due to the high volume of network traffic, it is challenging to achieve high performance for DPI in real time. In this thesis, a new DPI framework is presented that accelerates packet header checking and payload inspection on graphics processing units (GPUs). Various optimizations were applied to GPU-version packet inspection, such as thread-level and block-level packet assignment, warp divergence elimination, and memory transfer optimization using pinned memory and shared memory. The performance of the pattern-matching …

Affective And Cognitive Effects Of Awe In Predicting Hopelessness And Brooding Rumination, Eldita Tarani

Master's Theses

This study investigated the effects of awe, as a positive emotion, in ameliorating

depressive symptoms such as hopelessness and rumination. Previous research indicates that awe is unique compared to other positive emotions in that is elicited by information rich-stimuli that facilitate shifts in cognition as one attempts to accommodate this new information to their current frame of reference. In addition, awe was found incite a self- diminishing effect that contrast the inflated significance one places on the self, during negative self-referential thinking (e.g. hopelessness). We hypothesized that exposure to an awe stimuli (video) would prompt subjects to feel less hopeless …

Academic Barriers For Migrant Middle School Students In Salinas, California, Alexa Terhorst

Master's Theses

The educational barriers facing migrant students are examined in this research based on the experiences of teachers and Mexican migrant middle school students in Salinas, California. Through the research, I ask if academic barriers for migrant students differ from obstacles of their peers and if so, what are those differences? The barriers to migrant students’ education were explored through a literature review, examining themes of parental involvement, teacher–student relationships, student self-esteem, and the use of educational programs. Through snowball sampling, semi-structured interviews, and surveys, data were collected from four teachers and 18 migrant students to understand how these themes manifested …

Remains Of The 19th Century: Deep Storage Of Hydraulic Mining Sediment Along The Lower Yuba River, California, Tyler Kou Nakamura

Master's Theses

Since the onset of hydraulic mining in the Sierra Nevada in 1852, the environmental damage caused by displacement and storage of hydraulic mining sediment (HMS) has been a significant problem in downstream environments. Large volumes of mercury-laden HMS from the Yuba River watershed were deposited within the river corridor between the present site of Englebright Dam and the city of Marysville, CA, creating the anthropogenic Yuba Fan. However, there are outstanding uncertainties about how much HMS is still contained within this fan. To quantify the deep storage of HMS, I collected sediment from borings and outcrops along the lower Yuba …

A Feminist Focus Group Analysis Of Women's Experiences In Postpartum Yoga Classes With Babies Present, Ky Carnell Russell

Master's Theses

Women in the postpartum period face a number of physical and emotional challenges that research results indicate could be alleviated through exercise. Unfortunately, many new mothers are unable to participate in regular exercise due to a variety of personal and societally constructed obstacles. There is a growing trend to incorporate babies into yoga classes in an effort to increase the accessibility of postpartum exercise. There has been limited research conducted regarding the effectiveness of this emerging trend, and none have examined the feelings of participants engaged in mother and baby yoga classes. To address this gap in the literature, the …

Conservative Endodontic Access – Cone Beam Computed Tomography (Cbct)-Guided Preparation And Its Impact On Endodontic Referrals, Jeremiah M. Granados

Master's Theses

Conservative endodontic access (CEA) results in minimal access in comparison to traditional endodontic access (TEA) which is defined as straight-line access. Our survey suggested that while 81% of general dentists would prefer to restore a tooth that received a CEA preparation, only 33% considered it a determining factor for their endodontic referrals (100 out of 129 responded: Response rate 77.52%). To test our hypothesis that CBCT images aid endodontists in CEA preparation, 45 extracted molars were accessed by one endodontic resident using techniques of TEA (Group A), CEA (Group B) or CEA with preoperative CBCT images provided (Group C)(n=15 per …

Parent–Child Reciprocity? Parental Aggression And Oppositional Defiant Symptoms In Girls, Olivia J. Derella

Master's Theses

Objective. Evidence suggests that parents’ verbal aggression, corporal punishment, and inter-partner conflict are linked to children’s heightened conduct problems and oppositional defiant disorder (ODD). While children mutually influence parenting, strength of bidirectional relationships among these specific behaviors have been inconsistent across gender; further investigation is warranted to understand links between parental aggression and girls’ ODD symptoms. The current study tests independent reciprocal effects between specific forms of parental aggression and girls’ ODD dimensions of oppositionality, antagonism, and irritability. Method. Annual data from the longitudinal Pittsburgh Girls Study were used to evaluate parental aggression and girls’ ODD symptoms in a …

An Examination Of Daily Dietary Intake And Swallow Function In An Older Adult Population, Lillian A. Barone

Master's Theses

This study aims to determine the relationship, if any, of daily dietary intake of adult individuals living independently in the community and swallow function/ dysfunction. It appears that individuals modify their diet as they age and the correlation between this awareness of diet modification and dysphagia is unclear. Using the Yale Swallow Protocol and a study specific questionnaire, this relationship was examined. The results indicate future research should focus on the bi-directional relationship between malnutrition and dysphagia in the aging, community dwelling population.

Perceptions Of Hate Crimes: The Importance Of Victim Characteristics, Megan O. Iacocca

Master's Theses

Hate crimes in the United States are a growing problem that communities and affected individuals are struggling to address. Little research has been conducted regarding victim and crime characteristics’ (specifically, the SES of victim and level of bias clearly present in the incident) effects on objective evaluation. This study contains three segments, each building off the last and incorporating additional manipulations to assess non-victim interpretation of possible hate crime events. Across all phases, participants were randomly presented with a fake news story depicting a possible hate crime, in which the victim’s socioeconomic status, race, character, and presence of a racial …

Measurement And Analysis Of The Physical And Climatic Distribution Environment For Air Package Shipment, David Guadagnini

Master's Theses

The modern air parcel distribution industry has significantly grown to become one of the most commonly employed methods to quickly transport goods throughout the world. Although it comes with many benefits, including higher speed, greater reliability, and tighter security, the multimodal transport system within it can expose packages to a wide variety of climatic and physical distribution hazards. In a single route of transportation, packages could be included in different types of small delivery vans, large commercial semi trucks, cargo dollies, feeder aircraft, and high altitude commercial jetliners. The varying hazard level presented during distribution could directly weaken the packaging …

Pink And Dude Chefs: Efficacy Of An Online Train-The-Trainer Mechanism And Student Program Outcomes, Jacqueline Chen

Master's Theses

Background: The rate of overweight and obesity among adolescents aged 12-19 years has quadrupled since 1980. Reducing obesity is a key public health priority, as obesity is associated with individual and population-level health and economic consequences. Afterschool-based obesity prevention programs that aim to develop nutrition and culinary self-efficacy have shown promise. However, the level of aptitude among program instructors is directly correlated with student success, suggesting the importance of effective train-the-trainer (TTT) mechanisms for implementing and scaling up these strategies.

Pink and Dude Chefs (PDC) is an afterschool nutrition education and culinary skills program for middle-school adolescents aged between 11-14 …

The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byproduct, Irene Jennifer Kaufman

Master's Theses

In addition to proving an excellent source of nutrients, eggs are used in the food, cosmetic, and biotechnology industries for their rheological and bioactive properties. Much of the potential for the added value is in individual components of the egg, rather than the whole egg. At low speed centrifugation, yolk separates into two distinct fractions—granules and plasma. It is becoming increasingly popular in the industry to remove the plasma fraction of the egg yolk to use for its livetins, particularly immunoglobulin Y, leaving behind a granule by-product (“yellow cake”). Previous research has shown potential added-value from the granule fraction, especially …

Mass Estimation Through Fusion Of Astrometric And Photometric Data Collection With Application To High Area-To-Mass Ratio Objects, Matthew Richardson

Master's Theses

This thesis work presents the formulation for a tool developed in MATLAB to determine the mass of a space object from the fusion of astrometric and photometric data. The application for such a tool is to better model the mass estimation method used for high area-to-mass ratio objects found in high altitude orbit regimes. Typically, the effect of solar radiation pressure is examined with angles observations to deduce area-to-mass ratio calculations for space objects since the area-to-mass ratio can greatly affect its orbital dynamics. On the other hand, photometric data is not sensitive to mass but is a function of …
