Effects Of Input Modality On Capturing Notes, Chaya Bijani

Master's Theses

The features of the smartphone make it an indispensible commodity of Western urban lifestyles. However, the most common problems of using a mobile device for work-related activities are limited screen space and poor input techniques. People in the workforce whose daily job entails being in a mobile environment generally prefer to carry light, mobile devices along with a pen and a notepad. The purpose of this study was to investigate optimal input modality for taking notes. The three modes of input evaluated were spoken notes, typing on the phone, and writing by hand using a pen and paper. The variables …

Seeing Success: Biographies Of Low-Income Students, Julia M. Morrice

Master's Theses

The purpose of this narrative ethnographic study was to explore the success stories and lived experiences of six low-income students, utilizing an asset-based approach and attention to cultural wealth. Low-income students are less likely to attend college, and those that do are less likely to complete a degree. There is presently a lack of asset-based research that explores the successes of low-income students. A semi-structured interview protocol yielded biographical narratives of low-income students, which included discussions about identity and provided insight into the cultural wealth possessed by low-income students. In an effort to better understand the use of visual methodologies …

Chasing Rx: A Spatial Ethnography Of The Crossfit Gym, Matt Crockett

Master's Theses

CrossFit is a group fitness program that incorporates a variety of weightlifting and gymnastic movements performed at high intensities. Although there is growing research on CrossFit’s physiological and behavioral outcomes, few studies have qualitatively examined the program’s psychological and sociological characteristics. Drawing from Henning Eichberg’s (1998) work on spatial geography, this five-month ethnographic study examined the space and place of two San Francisco Bay Area CrossFit gyms as an introduction to a broader discussion on CrossFit subculture and evolving discourses about the body, health, and fitness. Specifically, three major themes about the CrossFit space emerged from the participant-observation data, including: …

Tales Of Archaeological Places: Visualizing Mayan Pre-Colonial Settlement Patterns, Angela Ivanov

Master's Theses

In order to visualize ancient Mayan settlement patterns and demography through time, data derived from 26 published archaeological sites were collected and plotted onto three discrete map media. These data were subdivided into six time periods ranging from Pre-Classic to Post-Classic, and were simulated for each map medium. Specific attention was given during the selection of geographical locations, natural landscape features, map annotation, layers and coordinates. Tabulated information were site names, coordinates, site founding dates, site decline/abandonment dates, and estimated population. Combined with existing country base map layers downloaded from online geographical sources and time series animation (an animated map), …

Structure, Construction, And Geochemistry Of The Cretaceous Seven-Fingered-Jack Intrusive Complex In The Klone Peak Area, North Cascades, Washington, Kelly N. Dustin

Master's Theses

The highly elongate Seven-Fingered-Jack intrusive complex (SFJIC) of the North Cascades, Washington provides an excellent opportunity to study the construction, geochemistry, and structure of a well-exposed mid-crustal pluton. The interior ~92 Ma Main Body tonalite has markedly heterogeneous and mafic domains that may represent interactions between multiple batches of melt. The ~78 Ma marginal Kelly Mountain suite includes a mafic complex containing abundant hornblendite, diorites of variable heterogeneity, and tonalite. Field mapping and structural, petrographic, and geochemical analyses are interpreted to indicate that this intrusive complex was built incrementally by many batches of melt. The dominantly NW-striking and NE-dipping magmatic …

Efficient Message Propagation In Dense Linear Ad-Hoc Networks, Shiva Moballegh

Master's Theses

In this thesis, the dynamics of the cooperative broadcast in high density 1-dimensional (1D) networks is studied using multiple levels of relays. The benefits of the cooperative broadcast in terms of transmission range and power efficiency are evaluated by approximating the network as a continuum of nodes. Two transmission protocols are studied, the single-shot transmission and the continuous source transmission. In the single-shot transmission, the source node transmits a single message, whereas in the continuous source transmission, it transmits independent messages periodically adding signal interference into the picture. For each case, the analytical expressions for successful broadcasting are presented as …

Measuring Tsunami Exposure And Pedestrian Evacuation Potential For The City Of Alameda, California, Evacuation Playbook Phases, Jeffrey Peters

Master's Theses

A maximum tsunami inundation zone modeled by the California Geological Survey (CGS) is currently the basis for all tsunami evacuations in California, although CGS is developing Evacuation Playbooks of specific event-based evacuation phases. This report estimates population exposure for the Alameda, CA, Evacuation Playbook Phases since past U.S. Geological scientific reports estimated a large difference in numbers of Alameda residents in the maximum inundation zone when compared to an event-based inundation zone. A pedestrian evacuation analysis using an anisotropic, path distance model was also conducted to understand the time it would take for populations to reach high ground by foot. …

A Comparison Of Alternative Interface Designs For Planning Software, Rachna Tiwary

Master's Theses

This study investigated the impact of varying the interface design of a software planning tool in a specific domain of the Attitude Determination and Control Operator (ADCO, where ADCO refers to a group or an individual was studied). This study extended a prior study that compared two entirely different interfaces of a software planning tool, LEGACY and NEW, and by which it was found that the NEW interface better matched the underlying domain structure and resulted in improved performance. The current study looked into the impact of varying the levels of presentation of the elements of a plan on user …

Pace, Academic Progress, And The Antecedents Of Student Motivation, Aaron Randall Hiatt

Master's Theses

The research examined the impact of the pace requirement of the 2010 program integrity legislation at a single graduate institution to gauge its potential for fulfilling the legislation’s stated purpose of increased likelihood of student success. The study determined that there have been changes in registration behavior (particularly in course drop behavior that reduces the number of credits calculated as attempted each semester) since the case institution introduced the pace requirement in Fall 2011. An increase in course completion efficiency was also found. The doctoral candidacy qualifying phase was singled out for a more refined examination, which was loosely tracked …

Multivariate Remote Process Sensing For Online Quality Control Of Injection Molding, Xinyao Tang

Master's Theses

A new wireless multivariate sensor (MVS) is designed, prototyped, structurally embedded into a mold structure to provide in situ feedback of four process states within mold cavity: melt temperature, melt pressure, melt velocity and melt viscosity, which closely correlate to the quality of manufactured products through the constitutive viscoelastic behavior of the polymer being processed. The developed MVS enables the improved observability of injection molding and provides a new process instrumentation and control methodology that sets up, assures, and optimizes the quality of injected products. Relationship between the key in-process states and quality characteristics (e.g., thickness and width of the …

The Effects Of Robot-Child Interactions On Interpersonal And Intrapersonal Coordination, Kinga Palatinus

Master's Theses

Coordination is crucial throughout development, from motor development and language acquisition to children’s play and other social interactions. Based on the links between motor and social behavior, proper coordination should help children connect socially with others. Being part of a larger study investigating the effects of a multisystem intervention tool for children with ASD, this work examined the effect of robot-child interaction on interpersonal and intrapersonal coordination in typically developing children. 5-year-olds and 7 year-olds participated in a four-week training protocol, where children had to copy the movements of a small humanoid robot. Measures of cross recurrence quantification analysis revealed …

Sequential Logic Circuits Using Spatial Wavefunction Switched (Sws) Fets, Neeraja Jagadeesan

Master's Theses

In this thesis, sequential logic circuits have been implemented using spatial wavefunction-switched field-effect transistor (SWSFET). The spatial wavefunction-switched field-effect transistor (SWSFET) is one of the promising quantum well devices that transfers electrons from one quantum well channel to the other channel based on the applied gate voltage. This eliminates the use of more transistors as we have coupled channels in the same device operating at different threshold voltages. This feature can be exploited in many digital integrated circuits thus reducing the count of transistors which translates to less die area. The simulations of basic sequential circuits like SR latch, D …

The Final Whistle: An In-Depth Analysis Of How Elite Transfer Student-Athletes Adapt To Life After Intercollegiate Sport, Julianne Hubbard

Master's Theses

Since elite intercollegiate student-athletes often elect to transfer institutions for reasons of athletic dissatisfaction, it was hypothesized that members of this population have strong, exclusive athletic identities, making the transition out of sport extremely troublesome. The following research study utilized a mixed-methods approach to examine the athletic retirement experiences of elite transfer intercollegiate student-athletes. Nine former NCAA Division I women’s soccer players provided quantitative and qualitative information regarding athletic identity, transferring, and retirement from elite sport. Using the Athletic Identity Measurement Scale (AIMS) developed by Brewer et al. (1993), ‘at-risk’ individuals likely to have experienced negative transitions from sport were …

Refugee Resettlement And Family Reunification In Canada, Yohannes Kenningd Woonssi Sawassi Ys Sawassi

Master's Theses

This thesis addresses the plight of Sub-Saharan Africans who are now Canadians and are trying to settle in a new country in order to reunite with their family members. However, rather than assisting with process of resettlement, current Canadian policy has the opposite effect. It appears to create a route by which people can sponsor their loved ones, but in reality the nature of the process is arduous and filled with time delays, regulatory and processing issues and other kinds of difficulties. Consequently, what therefore appears as a hopeful situation ends up creating despair. This situation is particularly hard for …

Into The Red: A Look Into The Reasons Why Refugees Decide To Flee, Settle Or Migrate To And From Morocco, Fadeelah E. Holivay

Master's Theses

This research paper explores some of the main reasons why refugees and asylum seekers, particularly from sub-Saharan African countries, embark on a journey and decide to settle, flee or migrate to and from Morocco. Because of this phenomenon, Morocco has seen a 96% increase of refugees migrating to the borders of Morocco each year for the past three years. Many say that this astonishing increase of migrants choosing Morocco is due to such factors as: wars breaking out regionally across central African and Middle Eastern countries causing them to flee; Morocco being a culturaly diverse francophone country whose laws and …

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, …

Exhibition, Featuring, Catherine Duggan

Master's Theses

Exhibition, Featuring is a collection of poems inspired by art, life, and history intertwined with the very center of humanness, convergence of heart and brain. The poems assembled here attempt to recreate the sensation of memory and remembering, and at times, trying to forget. Concerned with language and the ways in which we communicate with others, the lines weave in and out of conversation, evoking daily interac­tions and thoughts carried within us, continuous as breathing. The collection is divided into five parts, each establishing a variance of the whole—all parts a harmony. The reader will discover formal poetry, poems evoking …

A Comparison Between High-Risk And Low-Risk Children With Autism Spectrum Disorder, Kathryn Bradbury

Master's Theses

Due to the elevated recurrence rates in high-risk younger siblings of children with ASD, the population is frequently used to examine early ASD symptomatology. However, the representative nature of this population compared to the general population of children with ASD is unknown. Previous research also suggests that parents of children with ASD raise concerns about the development of subsequent children earlier than first-time parents or parents of typically developing children. Whether an actual discrepancy exists in the attainment of milestones in these populations has not yet been assessed. The current study proposes to compare high- and low-risk children with ASD …

Parenting Stress In Parents Of Young Children With Autism Spectrum Disorders: The Role Of Child Characteristics And Social Support, Lauren D. Haisley

Master's Theses

The current study drew on the Double ABCX model of stress to explore the relationship between parenting stress in parents of children with an autism spectrum disorder (ASD) and factors contributing to heightened levels of stress. Specifically child characteristics, pile-up demands, external resources and parent perception were examined in cross-sectional samples of parents of children 2 (Time 1), 4 (Time 2) and 8 (Time 3) years of age. Additionally a comparison sample of parents of 2 year olds with a developmental delay (DD), and two longitudinal subsamples (2-4 and 4-8) were utilized. Prior to the child’s diagnosis (Time 1), parenting …

Recruitment Patterns Of The Fouling Community On Eelgrass In Long Island Sound, Diana Lancaster

Master's Theses

The seagrass Zostera marina (eelgrass) is typically found in shallow protected areas of portions of eastern Long Island Sound (LIS). Although the species and its associated ecosystem have been well studied in many places, work in LIS has been limited. A field study was conducted to assess the fouling communities associated with eelgrass beds around Pine Island, in eastern LIS. Samples were collected from four sites between July and October, 2011. A total of 15 species of fouling organisms were found on eelgrass leaves throughout the study period. Recruitment patterns varied spatially and temporally. Differences in the composition of fouling …

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 …

The Queer And The Bodily: Explorations Of Power In Women's Visionary Writing In The Book Of Margery Kempe 2014, Jayne Emerson Stacconi

Master's Theses

The provocative Book of Margery Kempe is a seminal text in the history of female authorship. Claiming to be the first written autobiography, The Book serves as a literary representation of womanhood during the late fourteenth to the fifteenth centuries when Margery was writing, and also speaks to circulating medieval discourses of religion, pilgrimage, and sexuality. Participating in medieval women’s visionary writing as a genre, Margery’s visionary power is a tool by which she is able to emancipate herself from the limiting roles of wife and mother. Additionally, by working within the conventions of visionary writing, Margery is able to …

The Effects Of Atomic Oxygen On The Outgassing Properties Of Spacecraft Materials, Eli Z. Gurnee

Master's Theses

The space environment contains many harsh characteristics that are harmful to spacecraft and threaten the success of space missions. Atomic oxygen (AO) and outgassing are among the chief concerns that spacecraft engineers must design for in order to ensure the safety of a spacecraft. AO is monatomic oxygen (O1) that is created when Ultraviolet (UV) radiation photochemically disassociates diatomic oxygen (O2) in space. AO is the dominant atmospheric constituent between 175 and 600 km, and is a great concern in low earth orbits. Orbital AO has an average impact energy of 4.5 ± 1 eV with orbiting spacecraft and is …

A Pareto-Frontier Analysis Of Performance Trends For Small Regional Coverage Leo Constellation Systems, Christopher Alan Hinds

Master's Theses

As satellites become smaller, cheaper, and quicker to manufacture, constellation systems will be an increasingly attractive means of meeting mission objectives. Optimizing satellite constellation geometries is therefore a topic of considerable interest. As constellation systems become more achievable, providing coverage to specific regions of the Earth will become more common place. Small countries or companies that are currently unable to afford large and expensive constellation systems will now, or in the near future, be able to afford their own constellation systems to meet their individual requirements for small coverage regions.

The focus of this thesis was to optimize constellation geometries …

Examining Ambiguities In The Automatic Packet Reporting System, Kenneth W. Finnegan

Master's Theses

The Automatic Packet Reporting System (APRS) is an amateur radio packet network that has evolved over the last several decades in tandem with, and then arguably beyond, the lifetime of other VHF/UHF amateur packet networks, to the point where it is one of very few packet networks left on the amateur VHF/UHF bands. This is proving to be problematic due to the loss of institutional knowledge as older amateur radio operators who designed and built APRS and other AX.25-based packet networks abandon the hobby or pass away. The purpose of this document is to collect and curate a sufficient body …

The lesson plans examined were from pre-service teachers who enrolled in a methods class, Contemporary Art in Society, at the University of Northern Colorado. The class provided methods and techniques to teachers for creating arts integrated lesson plans from contemporary artworks. The findings of this study showed evidence that the methods used in Contemporary Art in Society to instruct teachers how to use contemporary artworks within arts-integrated lesson plans provided …

Vascular Reactivity In Newly-Formed And Mature Arterialized Collateral Capillaries, Sara K. Hellstrom

Master's Theses

Peripheral arterial occlusive disease (PAOD) is a globally-prevalent cardiovascular disease in which atherosclerotic plaques narrow arterial lumen diameters and restrict blood flow to downstream tissues. The impact of these occlusions can be mitigated by collateral vessels that connect parallel arterial branches and act as natural bypasses to maintain perfusion. In animal models that lack collateral arterioles, capillaries that connect terminal arteriolar segments can arterialize and form functional collaterals following an ischemic event; however, in the early stages of development, vasodilation is impaired. We explored the mechanism of impaired vasodilation in arterialized collateral capillaries (ACCs) and pre-existing collaterals (PECs) by evaluating …
