My Team Drinks: An Analysis Of Alcohol Consumption Norms Among Adolescent Athletes, Laura Beth Jones

Master's Theses

Alcohol use among adolescents results in a greater risk of lifetime alcohol abuse and dependence. Some research suggests that perceived peer norms about drinking are the strongest predicting factor of alcohol–related behaviors (ARBs) among adolescents. Previous research on whether sports participation is related to adolescent alcohol consumption has resulted in mixed findings. For this study, perceived norms were further delineated between descriptive and injunctive norms. The goal of this research was to determine whether there were differences between sport types (team vs. individual) in alcohol consumption patterns and whether sport type moderated the predictive strength of perceived norms on alcohol …

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 …

Use Of Stair Prompts To Encourage Physical Activity, Nima Chhay

Master's Theses

Stair prompts can encourage stair use in both public and private settings and thereby increase overall physical activity. Stair visibility in multilevel buildings increases stair use. For this study, an intervention using a modified New York City Department of Health and Mental Hygiene stair prompt was implemented to encourage stair use in an academic setting. The modification included a time management theme, chosen because individuals in this setting may find taking the stairs to be faster than taking the elevator. To evaluate the effectiveness of the modified stair prompt, two buildings--one with hidden stairs and one with visible stairs--were selected …

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 …

Performance And Gta Training: Understanding An Adaptation Of Boal's Forum Theatre For New Teachers, Tiffany Harbrecht

Master's Theses

The Communication Studies Department at San José State University adapts Boal's Forum Theatre to provide its graduate teaching associates (GTAs) a space for cooperatively re-imagining their way through challenges and concerns they may (or do) face during teaching. This research fills a gap in our disciplinary understanding of how new teachers experience forum theatre and the substantive differences and difficulties that arise when implementing it in trainings that are not focused on challenging oppression. Chiefly, participants risk conflating forum theatre with role-play and losing Boal's theory; while fusing its ideas this way might appear as a way to problem-pose with …

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

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 …

Propriety Of Self-Disclosure On Facebook: An Examination Of Its Impact On Credibility, Katherine Colleen Ireland

Master's Theses

This experimental study examined the effects of the propriety of computer-mediated teacher self-disclosure on perceptions of teacher credibility and how that relationship is moderated by ethnicity. Participants were assigned to one of four conditions: White Appropriate, Latina Appropriate, White Inappropriate, and Latina Inappropriate. Participants answered questions about the instructor's perceived credibility. Results suggest that teachers who engaged in appropriate self-disclosure were rated higher on teacher credibility than those with inappropriate Facebook® profiles. There was no main effect for ethnicity. Implications for classroom pedagogy, technology use, and areas for future research are discussed.

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 …

Analysis And Application Of Transmission Line Conductors, Orin Laney

Master's Theses

Skin effect is usually a concern reserved for radio frequency design and for high current conductors used in utility power distribution. Proximity effect between adjacent conductors has traditionally been a concern for the design of magnetic windings and other applications involving wire bundles. The rise in the ubiquity of high speed bit streams and other signals of very wide bandwidth has broadened the range of applicable contexts and increased the need to account for such effects. This

is especially true for transmission lines used to interconnect critical signal paths in applications ranging from microelectronic devices to the signal integrity of …

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 …

Use Of Dna Sequences To Identify Forensically Important Fly Species In The Coastal Region Of Central California (Santa Clara County), Angela T. Nakano

Master's Theses

Forensic entomology has gained prominence in recent years, as improvements in DNA technology and molecular methods have allowed insect and other arthropod evidence to become increasingly useful in criminal and civil investigations. However, comprehensive faunal inventories are still needed, including cataloguing local DNA sequences for forensically significant Diptera. This multi-year fly-trapping study was built upon and expanded a previous survey of these flies in Santa Clara County, including the addition of genetic barcoding data from collected species of flies.

Flies from the families Calliphoridae, Sarcophagidae, and Muscidae were trapped in meat-baited traps set in a variety of locations throughout the …

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.

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. …

Novel Systematic Phase Noise Reduction Techniques For Phase Interpolator Clock And Data Recovery, Yu Feng

Master's Theses

This work focused on high-speed source-synchronous clock and multi-channel data receivers for inter-chip communications. Designs of inter-chip communication are becoming increasingly difficult with the rise in clock rates and the reduction in voltage supplies. Data transmissions at rates of gigabits per second require a fast and accurate clock and data recovery system on the front end of receivers.

Many designs allow for source-synchronous clocking architectures, but this work focused on a dual-loop with a phase-locked loop for frequency tracking and phase integrators for tracking each individual data lane. Limitations with the phase interpolator architecture cause systematic jitter, reducing the data …

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 …

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 …

Funding Sources Of Impactful And Transformative Research, Barrett Anderson

Master's Theses

Understanding how the most important scientific articles have been funded can help inform and improve future funding decisions. Importance is here defined as science that, in the metaphor of the tree of knowledge, plays a structurally significant role (e.g., creates new branches of knowledge or transforms existing ones). The structural significance of articles is broken down into two submeasures: citation count and "generativity" (a novel measure defined as being highly cited and also leading to a comparatively large number of other highly cited articles). Generativity is an attempt to provide a quantitative operationalization that should correlate with transformativeness, a concept …

Evaluating Hypotheses That Explain Non-Continuous Responses To Syllable Periods ("Skipping") During Phonotaxis By Female Acheta Domesticus, Tori Joy Steely

Master's Theses

One way to classify female cricket phonotactic response is as "non-skipping" or "skipping." "Skipping" is defined as crickets that respond to a non-continuous range of calling songs. This investigation evaluates the temporal aspects of typical phonotactic protocols and attempts to determine if "skipping" is due to a filtering mechanism or if "skipping" is an artifact of testing protocol. Rather than a notch filter or testing parameters inhibiting a phonotactic response to a syllable period within the range of a band pass filter, I hypothesize that "skipping" occurs as a result of the probabilistic nature of phonotaxis.
