The Effect Of Surface Treatment On Nickel Leaching From Nitinol, Daniel Lawrence Leobrera Madamba

Master's Theses

Nitinol is widely used as a biomaterial for implantable medical devices but can be susceptible to nickel leaching. Our research was aimed at determining nickel leaching from surface treated Nitinol samples, treated as follows: mechanical polishing (untreated), oxidation, and nitriding+oxidation (5 different nitriding temperatures). Five specimens from each category were immersed in 40 mL PBS solution and incubated at 37°C over 91 days. Nickel concentration readings were taken at regular intervals. After 91 days, the average nickel concentration in the PBS solution was (a) 0.223 mg/L, SD 0.017, untreated, (b) 7.68 mg/L, SD 6.405, 1000°C nitriding+oxidation, and (c) 3.914 mg/L, …

Designing Affordances On Embedded Interfaces, Gabriela Madalina Istan

Master's Theses

The purpose of this study was to examine the effects of a user interface on users' performance during an online shopping checkout task. Two interfaces were developed using the principles of Rasmussen's SRK model: a high-affordance and a

low-affordance interface. Seventy undergraduate and graduate students performed a simulated online shopping task with the two interfaces. It was hypothesized that the high-affordance interface would require less time and fewer clicks to conduct the shopping task when compared to a low-affordance interface. In addition, it was predicted that participants would prefer the high-affordance interface. The findings revealed participants spent more time on …

Effects Of White Space On Consumer Perceptions Of Value In E-Commerce, Sin Lee Loh

Master's Theses

As e-commerce becomes an increasingly large industry, questions remain about how the isolated effects of design elements on websites influence consumer perceptions and purchasing behavior. This study used a quantitative approach to measuring the effect of a ubiquitous element of design, white space, on the perception of the monetary value of individual items. White space is a key component of design and website usability, yet it has been shown to be related to the perception of luxury. Little is known about the direct relationship between manipulation of white space and the outcomes on consumer perceptions of value in an e-commerce …

The Effects Of Indoor Climbing Route Rating Manipulation On Participant Climbing Self-Efficacy, Phillip James Sandlin

Master's Theses

This quantitative study utilized a classical experiment design to explore the

effects of manipulation of indoor climbing route ratings on the climbing self-efficacy of 90 indoor rock climbers. Controversy surrounding the accuracy of the assigned ratings of indoor climbing routes is commonplace at indoor climbing facilities. For indoor rock climbers to accurately assess their abilities, set appropriate goals, and monitor their progress, they must be able to choose climbs that accurately represent their desired level of challenge. Statistical analysis of the data did not support a relationship between manipulation of climbing route ratings and any changes in participant climbing self-efficacy. …

An Ecological Assessment Of Insect Diversity At Organic Central Coast Vegetable Farms On Two Spatial Scales, Emily Musgrave

Master's Theses

Modern industrial agriculture is the principal cause of anthropogenic land use changes for terrestrial ecosystems. Approximately 40% of the planet's land surface, or half of the habitable area, is now composed of agricultural landscapes. The simplification and industrialization of agriculture are the biggest drivers of global biodiversity loss, especially on Californian's Central Coast. Diversified organic agriculture, however, may offer some refuge for non-crop species. In this study we analyzed insect and plant biodiversity on and adjacent to organic vegetable farms on the Central Coast of California at two spatial scales, the landscape-scale and a smaller within-farm scale. At the landscape-scale, …

Mastermind-Like 1-Dependent Notch Target Gene Activation Requires A Sequence-Paired Site And A Tata Box, Cassandra Agbayani Ramos

Master's Theses

Notch signaling plays an important role in mammalian cellular proliferation, apoptosis, and differentiation. To activate target genes, the Notch intracellular domain (NICD) forms a complex with CBF1 and Mastermind-like protein (MAM). The Notch activation complex binds to a response element containing the consensus sequence RTGRGAR (R= purine) on target gene promoters. The promoter of one well characterized target gene, Hes1, contains four Notch response elements (NREs). Site-directed mutagenesis and reporter gene assays were used to examine the activation of Hes1 by mutating individual and combinations of NREs. Results indicated that NREs 2 and 4 are important for Hes1 activity, confirming …

In light of these studies, the history of Gezer is inspected.

The site is chronologically divided into three periods, the Bronze Age, the Early Iron Age, and the Late Iron Age. Using both historical and archaeological sources, the occupational history of Gezer is outlined, highlighting ethnically …

Restoring Native Plants Following Invasive Malephora Crocea (Coppery Iceplant, Aizoaceae) Eradication On Anacapa Island, Nathan William Hale

Master's Theses

To avoid unintended complications of invasive species eradication, it is important to understand the potential implications of the techniques used in species eradication efforts. This study aimed to compare how different methods of removing Malephora crocea affect the survivorship of planted seedlings of native perennial plants on Anacapa Island. Employing a randomized complete block design in an M. crocea stand, three removal treatments were tested: 1) hand-pull; 2) spray with herbicide and leave skeletons; and 3) spray and then remove skeletons after 2.5 months. In each treatment, seedlings of three species (Leptosyne gigantea, Frankenia salina, and Grindelia …

Big Shot, Annie Joy Heath

Master's Theses

There are many forms of child abuse. Some forms leave visible scars, and other forms leave invisible ones. Both forms, and especially a combination of the two, change the behaviors as well as the decision making of the person who has been abused, whether a child or an adult. And while an adult may choose not to have the abuser in her life, a child rarely has that choice. The child usually loves her parents unconditionally and cannot comprehend why she is being mistreated. As a teenager and then an adult, she often times looks for the same type of …

This Could Be A Game!": Defining Gamification For The Classroom, Darcy Elaine Osheim

Master's Theses

Instructors find a gap between what they experienced in school in the mid-to-late 20th century and the experiences of students entering college in 2012/13. In the United States, the influx of almost universal access to technology has marked this generation in a way the previous generations must work to understand, and gamification is a strategy used in areas like marketing to gain participation from this age group. Gamification is a strategy that employs game mechanics, techniques, and theory in areas that traditionally are not set up to function like a game. The purpose of this study was to define gamification …

Experiences Of Coping With Injury In Division I Athletes From Low-To-Middle Socioeconomic Status Backgrounds, Matthew Philip Bejar

Master's Theses

Injuries inevitably occur in any sport at any level. The integrated sport injury model is one of the most extensive frameworks to address the psychological responses to athletic injury. While this model posits that socioeconomic status (SES) influences how an athlete cognitively, emotionally, and behaviorally responds to an injury, no research has substantiated this claim. Low SES individuals experience an exceptional amount of stress, which may complicate how they cope with a negative event. The coping strategies employed by an athlete can have major implications on rehabilitation adherence, recovery time, and psychosocial well-being. The purpose of this study was to …

The purpose of the study was to predict individual intentions to leave science, technology, engineering, and mathematics (STEM) field jobs. Psychological predictors were gender, the need to belong, self-esteem, perceived personal discrimination, and perceived group discrimination. We used the Amazon Mechanical Turk to recruit participants and Survey Monkey to conduct an online survey. Participants were 174 men and women who worked or studied in STEM fields. Two-step hierarchical linear regression analyses were performed to analyze the data. As a result, we found that all predictors mentioned above accounted for the variance in the intention to leave a job. Self-esteem and …

Fostering Affective Commitment And Work Engagement Through Mentoring, Luis Portillo

Master's Theses

Past research on mentoring has focused primarily on the benefits that protégées and mentors derive from their mentoring relationships. However, little research has been devoted to revealing the ways in which mentoring can benefit organizations. To address this void, a sample of 124 protégées was used to investigate the relationships between satisfaction with a mentor, affective commitment (AC), and work engagement. Perceived organizational support (POS) was hypothesized as the mediator of the aforementioned relationships. Further, in order to identify the factors contributing to satisfaction with the mentor, this study examined the relationship between satisfaction with the mentor and mentorship type …

Internalized Oppression: Latino Narratives On Educational Experience, Carolina Avalos

Master's Theses

A qualitative study investigated the lived experiences and impact of internalized oppression within educational contexts. Six Latino-identified people--ages 22-38--who are current or former college students were interviewed about their early and adult educational experiences. A constant comparative methodology was used to identify commonalities found in participant narratives. Interview transcripts and field notes were analyzed to organize data into themes. Emergent themes included: (a) identity formation, (b) experience of racial micro-aggression in school, and (c) the value of acquiring an occupation being valued higher, in the household, than educational attainment. Findings provided insight into participant experiences with internalized oppression and educational …

Intra-Annual Changes In Population Parameters As Indicators Of Humpback Whale (Megaptera Novaeangliae) Migratory Behavior, Casey Clark

Master's Theses

Many techniques used to study animal migrations rely on observations of specific animals, which provide valuable information about individuals studied but do not capture population variability. By examining changes in population parameters, researchers may gain a better understanding of migratory behaviors. In this study, intra-annual changes in population parameters were used to study migratory behaviors of humpback whales off central California in 2011/2012. Data were compared with a historic dataset from 2004/2005. Parameters measured included sex ratio, pregnancy rate, mitochondrial DNA haplotype frequencies and mean δ13C and δ15N values. Weighted moving averages of the sex ratio were moderately effective at …

The Effectiveness Of Experiential Environmental Education: O'Neill Sea Odyssey Program Case Study, Lauren Elizabeth Hanneman

Master's Theses

Environmental education programs aim to develop participant awareness, sensitivity, and understanding of their affective relationship to the natural environment through conceptual knowledge and personal experiences. Previous findings have suggested that participation in environmental education programs leads to short-term positive increases in environmental knowledge, pro-environmental attitudes, and intentions to act in environmentally responsible behaviors; however, few studies have included long-term, follow-up assessment. This research provided an analysis of the effectiveness of the O'Neill Sea Odyssey (OSO) education program in fostering a long-term awareness of personal responsibility about ocean pollution among student participants.

A survey administered to 261 students from the greater …

Assessing The San José State University Simultaneous Polydrug Use Questionnaire -- Online (Sjsu Spuq -- Online) A Pilot Study, Joseph P. Hennessee

Master's Theses

Alcohol use is one of the most prevalent forms of drug use among college students. Because of the near ubiquity of college drinking, additional research is needed to determine whether such alcohol use is related to any cognitive impairment. Furthermore, many of those who use alcohol consume one or more additional drugs simultaneously, and little research has assessed whether such simultaneous polydrug use (SPU) has a further effect on cognitive functioning. This study was developed to bridge these two gaps in the literature and aid in the development of the SJSU SPUQ - Online.

Local Adaptation Of Two Cryptic Species, Lasthenia Californica And Lasthenia Gracilis, To Distinct Regions Within A Serpentine Outcrop, Teri Barry

Master's Theses

Intraspecific variation providing tolerance to specific edaphic conditions may contribute to population differentiation, speciation, and species coexistence. This process is often examined using reciprocal transplant experiments of closely related species in contrasting edaphic conditions. The two cryptic species Lasthenia californica and L. gracilis occur on a serpentine outcrop in parapatry at Jasper Ridge Biological Preserve. I hypothesized that each species would demonstrate greater fitness in its home range. A reciprocal transplant experiment was conducted in the field to determine home site advantage. Seedlings from each species were planted in both home ranges and in the transition zone where both species …

Zazie De Louis Malle : Une Traduction Intersémiotique, Clara Elahe Varjavandi

Master's Theses

In his novel, Zazie dans le métro (1959), Raymond Queneau reinvents the French language while telling the story of a young girl, Zazie, visiting her uncle in Paris for the weekend. The absurdities of the world are examined through her eyes as well as the effort by French society to forget the atrocities of World War II.

Because of its intricate use of language, Queneau's masterpiece seemed impossible to adapt to film. Yet, already in 1960, Louis Malle took it upon himself to convert the renowned novel into a film.

This thesis approaches the film as an intersemiotic translation rather …

The Genetic Diversity And Population Structure Of The Dugongs (Dugong Dugon) Of Thailand, Jessie Barr Bushell

Master's Theses

The dugong (Dugong dugon) is indigenous to the coastal waters of the Indo–Pacific Ocean and is vulnerable to extinction throughout its range due primarily to anthropogenic effects. In Thailand the population of dugongs is approximately 250 animals and is found in fragmented habitats along the Thai coast. Genetic studies were implemented in this study to assess regional genetic composition and determine if there is variation in the D–loop sequences or microsatellites consistent with philopatry to regions, by males or females, or indicating dispersal. Utilizing D–loop sequences, 27 haplotypes were found that grouped into three haplogroups that were not …

Made Marian: Myth And Reality In The Redondo Beach Public Library, 1895-1924, Lisa Blank

Master's Theses

Librarians have been depicted in the literature as missionaries, apostles, and crusaders, militant maid Marians spreading the gospel of the library spirit. This thesis examines the historical depiction of the "typical" early librarian by posing two key questions. First, to what extent was the work of librarianship different or unique compared to that of other middle-class female occupations? And second, in what way was the librarian herself distinct from other middle-class women; that is, what defining characteristics or life events brought her to and kept her in librarianship?

Utilizing local newspapers, official reports, and census and vital statistics data, this …

Strain Measurement Validation Using 3d Photogrammetry Techniques, Tori Chinn

Master's Theses

This project was conducted to validate the measurement of static strain and dynamic frequency in an aluminum beam using 3D photogrammetry technology against analytic modeling and conventional strain measurements. A review of the 3D photogrammetry literature was conducted and a summary is presented here. Static load displacement and strain were compared between analytical calculations, photogrammetric data, strain gauges, experimental measurements, and an FEA model. First mode forced vibration was validated between analytical work, FEA, accelerometers, and photogrammetric measures. Results yielded positive and repeatable correlations between photogrammetric data and analytical computations with most reliable results for displacement.

Effectiveness Of Peer Mentoring In First-Year Program Classrooms, Katherine Casey

Master's Theses

First-year programs (FYPs) for college students offer extended orientation to campus resources and provide first-time freshmen with essential skills for academic success, and many believe that the effectiveness of FYPs increases with the presence of peer mentors. The present study measured the added effectiveness of peer mentoring in FYP classrooms with knowledge of campus resources as a dependent measure. Ninety one first-year students in nine sections of FYP classes participated in this quasi-experimental study. Seven of the classes had peer mentors (n = 70), and the two control classes (n = 21) did not have peer mentors in the classroom. …
