Providing the user with good user experience is complex and involves multiple factors. One of the factors that can impact the user experience is animation. Animation can be tricky to get right and needs to be understood by designers. Animations that are too fast might not accomplish anything and having them too slow could slow the user down causing them to get frustrated. This study explores the subject of animation and its speed by trying to answer the following questions – 1) Do people notice whether an animation is present 2) Does animation affect the enjoyment of a transition? and …

Female college veterans face a host of struggles both personally and academically. Research that focuses primarily on female veterans’ wellness needs as they transition into civilian life is limited and this population is woefully understudied in comparison to male veterans. The purpose of this study was to describe and explore some of the wellness needs of female college veterans making the transition from military service to college/civilian life. Twelve hundred and thirty female veterans from a University Veterans Center were sent a recruitment email where 125 successfully completed a life satisfaction (Frisch, 1994), physical activity (Craig et al., 2003), resilience …

Hydrogel polymers have been the subject of many studies, due to their fascinating ability to alternate between being hydrophilic and hydrophobic, upon the application of appropriate stimuli. In particular, thermo-responsive hydrogels such as N-Isopropylacrylamide (NIPAM), which possess a unique lower critical solution temperature (LCST) of 32°C, have been leveraged for membrane-based processes such as using NIPAM as a draw agent for forward osmosis (FO) desalination. The low LCST temperature of NIPAM ensures that fresh water can be recovered, at a modest energy cost as compared to other thermally based desalination processes which require water recovery at higher temperatures. This work …

Facial Expressions Recognition using the Convolution Neural Network has been actively researched upon in the last decade due to its high number of applications in the human-computer interaction domain. As Convolution Neural Networks have the exceptional ability to learn, they outperform the methods using handcrafted features. Though the state-of-the-art models achieve high accuracy on the lab-controlled images, they still struggle for the wild expressions. Wild expressions are captured in a real-world setting and have natural expressions. Wild databases have many challenges such as occlusion, variations in lighting conditions and head poses. In this work, I address these challenges and propose …

This thesis examines the jazz jam session’s function in the constitution of jazz scenes as well as the identities of the musicians who participate in them. By employing ritual and performance studies theories of liminality, I demonstrate ways in which jazz musicians, jam sessions, and other social structures are mobilized and transformed during their social and musical interactions. I interview three prominent members of the jazz scene in the greater Phoenix area, and incorporate my experience as a professional jazz musician in the same scene, to conduct a contextually and socially embedded analysis in order to draw broader conclusions about …

Video conferencing applications, such as Skype, have long been used in classroom settings. Although musicians have been conducting online lessons for years, and institutions such as the Berklee School of Music and the Manhattan School of Music offer online music classes, scholarly research concerning online video conferencing music lessons is limited. Most studies of video conferencing lessons are based on subjective answers, making it difficult to yield conclusive results. As such, the only basis to evaluate the efficacy of video conferencing lessons are those from opinions. This study offers quantitative research on online video conferencing lessons. Between September and December …

With global environmental systems under increasing Anthropogenic influence, conservationists and environmental managers are under immense pressure to protect and recover the world’s imperiled species and ecosystems. This effort is often motivated by a sense of moral responsibility, either to nature itself, or to the end of promoting human wellbeing over the long run. In other words, it is the purview of environmental ethics, a branch of applied philosophy that emerged in the 1970s and that for decades has been devoted to understanding and defending an attitude of respect for nature, usually for its own sake. Yet from the very start, …

Climate change impacts are evident throughout the world, particularly in the low lying coastal areas. The multidimensional nature and cross-scale impacts of climate change require a concerted effort from different organizations operating at multiple levels of governance. The efficiency and effectiveness of the adaptation actions of these organizations rely on the problem framings, network structure, and power dynamics of the organizations and the challenges they encounter. Nevertheless, knowledge on how organizations within multi-level governance arrangements frame vulnerability, how the adaptation governance structure shapes their roles, how power dynamics affect the governance process, and how barriers emerge in adaptation governance as …

How does a university create a culture of affinity where students seek and maintain life-long connections to the institution? The purpose of this action research study was to examine how affinity increased or developed for undergraduate students at the Arizona State University Polytechnic campus through meaningful student-centric activities. Three theoretical frameworks guided the study including the work of Baumeister and Leary, Kuh, and Ajzen. In this mixed method study, quantitative data about affinity, attitude, toward Arizona State University was collected using pre- and post-intervention surveys and qualitative data were gathered through individual semi-structured interviews at the conclusion of the study. …

ABSTRACT The Wesley Bolin Memorial Plaza is located across the street from the state capitol building in Phoenix, Arizona. Here, pieces of Arizona’s history are commemorated through monuments and memorials. Monuments and memorials reflect how people have conceived their collective identity, especially when those choices are made in public spaces. The markers in the Wesley Bolin Plaza reflect the changing identity of Arizonans, both locally and in connection to national identity. Over time, they have become crucial to shaping the landscape and the historical memory of the city, state, or country. Of note, the memorials on the Arizona State Capitol …

The success or failure of projects is not determined only by procedures, tasks, and technologies, but also by the project team and its effectiveness. In order to lead project teams towards successful outcomes, project managers must maintain high quality relationships in the workplace. When looking at employees’ relationships in the workplace, Social Exchange Theory introduces two types of exchanges: employee-organization and leader-member exchanges. While both types of exchanges focus exclusively on the employee’s longitudinal relationships, the interpersonal relationships among the team members are usually overlooked. This research presents the results of a quantitative study of the interpersonal relationships of 327 …

In most of the work using event-related potentials (ERPs), researchers presume the function of specific components based on the careful manipulation of experimental factors, but rarely report direct evidence supporting a relationship between the neural signal and other outcomes. Perhaps most troubling is the lack of evidence that ERPs correlate with related behavioral outcomes which should result, at least in part, from the neural processes that ERPs capture. One such example is the NoGo-N2 component, an ERP component elicited in Go/NoGo paradigms. There are two primary theories regarding the functional significance of this component in this context: that the signal …

Participation in competitive sports by athletes who are physically disabled has increased dramatically in recent decades. Given this growth in participation, sports for disabled athletes represents a worthy area of exploration. The purpose of this research is to further understand what motivates people and athletes with physical impairments to partake in adaptive recreation and sport. This study will explore motivations for participation in adaptive sport within theoretical lenses of Achievement Goal Theory (AGT), Self-Determination Theory (SDT) and the Five-Factor Model by Omar-Fauzee and colleagues (2010). In addition, this study examined the relationship between motives with sense of community and life …

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is the 10th leading cause of death, worldwide. The prevalence of drug-resistant clinical isolates and the paucity of newly-approved antituberculosis drugs impedes the successful eradication of Mtb. Bacteria commonly use two-component systems (TCS) to sense their environment and genetically modulate adaptive responses. The prrAB TCS is essential in Mtb, thus representing an auspicious drug target; however, the inability to generate an Mtb ΔprrAB mutant complicates investigating how this TCS contributes to pathogenesis. Mycobacterium smegmatis, a commonly used M. tuberculosis genetic surrogate was used here. This work shows that prrAB is not essential …

A driving force for studies of water, alcohols, and amides is the determination of the role of hydrogen bonding. Hydrogen bonds can break and reform, consequently creating supramolecular structures. Understanding the role supramolecular structures play in the dynamics of monohydroxyl alcohols is important to understanding hydrogen bonding in more complex systems such as proteins. Since many monohydroxyl alcohols are good glass formers, dielectric spectroscopy in the supercooled regime is used to gather information about the dynamics of these liquids. Application of high external fields will reversibly alter the polarization responses of the material from the linear response. This results in …

One of the major issues confronting education in Arizona and across the United States has been the consistent low performance of culturally and linguistically diverse (CLD) students in comparison to their peers as evidenced by the disparity of the achievement gap at every level in the educational pipeline. A contributing factor has been the lack of teacher preparation focused on teaching CLD students. Preparation focused on a culturally responsive curriculum about dispositions and pedagogical knowledge and skills as well as field experience placement with CLD students have been previously identified areas to consider when training preservice teachers (PSTs). Therefore, this …

Features of the built environment (BE) are related to a wide range of health factors, including leisure-time physical activity (PA) and active forms of transportation. For working adults, worksite neighborhood is likely an important BE to better understand the impact of various factors on PA patterns. Compared to home neighborhood walkability research, worksite walkability has received relatively less attention. The objective of this project was to identify if worksite walkability was significantly associated with PA behavior. Aims: to evaluate 1) the PA variation explained by work walkability, 2) the moderating effects of person-level characteristics to the relationship between PA and …

Basilisk lizards are often studied for their unique ability to run across the surface of water. Due to the complicated fluid dynamics of this process, the forces applied on the water’s surface cannot be measured using traditional methods. This thesis presents a novel technique of measuring the forces using a fluid dynamic force platform (FDFP), a light, rigid box immersed in water. This platform, along with a motion capture system, can be used to characterize the kinematics and dynamics of a basilisk lizard running on water. This could ultimately lead to robots that can run on water in a similar …

Social identities are fundamental to the way individuals and groups define themselves. Archaeological approaches to social identities in the Andes emphasize the importance of group identities such as ethnicity and community identity, but studies of gender and age identities are still uncommon. In this dissertation, I build on these earlier approaches to Andean social identities and consider community, gender, and age identities at the site of Chiribaya Alta using case studies. The coastal Ilo Chiribaya polity is associated with the Andean Late Intermediate Period in the lower Osmore drainage of southern Peru. Previous analyses indicate that Chiribaya sites in this …
