Description
This dissertation sought to understand how leaders in a public-private strategic alliance collaboratively address complex community problems. The study responded to the gap in academic research of leadership and public relations in alliances to solve complex social issues, as well as the scant scholarly attention to alliance leaders' communications with stakeholders. Its findings corresponded to framing theory, stakeholder theory, SWOT (strengths/weaknesses/opportunities/threats) theory, complexity theory, and the subtopic of complex leadership -- all through the lens of public relations. This investigation culminated in the introduction of the C.A.L.L. to Action Model of Community Engagement, which demonstrates the confluence of factors that were integral to the alliance's success in eliminating chronic homelessness among veterans in Maricopa County, Arizona -- Communication, Alliance, Leadership, and Leverage. This qualitative case study used the method of elite or in-depth interviews and grounded theory to investigate the factors present in a community engagement that achieved its purpose. It served as a foundation for future inquiry and contributions to the base of knowledge, including 1) additional qualitative case studies of homeless alliances in other communities or of other social issues addressed by a similar public-private alliance; 2) quantitative methods, such as a survey of the participants in this alliance to provide triangulation of the results and establish a platform for generalization of the results to a larger population.

Description
In the delivery of a public service, meeting the needs of its users through cocreation has generated considerable research. Service users are encouraged to engage with public services through dialogue, sustained interaction, and equal partnership, wherein the role of the user changes from passive to active. As the relationship between service provider and service user evolves, researchers have sought to explain how resources, time, accessibility, and bandwidth may affect such relationships, specifically concerning the economically disadvantaged. While many researchers have focused on the logistical barriers that inhibit cocreation among the economically disadvantaged presented by such factors as cost and transportation, limited research has examined the relationship between the service provider and economically disadvantaged service user. Combining previous research, this study examines what economically disadvantaged service users actually do when they cocreate value with a public service by conducting 12 in-depth interviews with participants of SNAP-Ed, nutrition education for persons eligible for government assistance. The study's findings suggest that cocreation exists through relational characteristics of collaboration, isolation, acceptance, connection, and guidance that help in the development and maintenance of relationships, and that a relationship between service provider and user could be further typified by equality. This finding suggests that equality is an independent construct not necessary in the process of cocreation--a departure from previous research--but rather a way to approach the service provider/user relationship. This study is intended as a step toward examining cocreation through the development of organization-public relationships.

Description
This research compares shifts in a SuperSpec titanium nitride (TiN) kinetic inductance detector's (KID's) resonant frequency with accepted models for other KIDs. SuperSpec, which is being developed at the University of Colorado Boulder, is an on-chip spectrometer designed with a multiplexed readout with multiple KIDs that is set up for a broadband transmission of these measurements. It is useful for detecting radiation in the mm and sub mm wavelengths which is significant since absorption and reemission of photons by dust causes radiation from distant objects to reach us in infrared and far-infrared bands. In preparation for testing, our team installed stages designed previously by Paul Abers and his group into our cryostat and designed and installed other parts necessary for the cryostat to be able to test devices on the 250 mK stage. This work included the design and construction of additional parts, a new setup for the wiring in the cryostat, the assembly, testing, and installation of several stainless steel coaxial cables for the measurements through the devices, and other cryogenic and low pressure considerations. The SuperSpec KID was successfully tested on this 250 mK stage thus confirming that the new setup is functional. Our results are in agreement with existing models which suggest that the breaking of cooper pairs in the detector's superconductor which occurs in response to temperature, optical load, and readout power will decrease the resonant frequencies. A negative linear relationship in our results appears, as expected, since the parameters are varied only slightly so that a linear approximation is appropriate. We compared the rate at which the resonant frequency responded to temperature and found it to be close to the expected value.

Description
Supernovae are vital to supplying necessary elements to forming bodies in our solar systems. This project studies the creation of a subset of these necessary elements, called short-lived radionuclides (SLRs). SLRs are isotopes with relatively short half-lives and can serve as heat sources for forming planetary bodies, and their traces can be used to date stellar events. Computational models of asymmetric supernovae provide opportunities to study the effect of explosion geometry on the SLR yields. We are most interested in the production of \iso{Al}{26}, \iso{Fe}{60}, and \iso{Ca}{41}, whose decayed products are found in our own solar system. To study the effect of explosion asymmetries in supernovae, we use TYCHO stellar evolution code, SNSHP smooth particle hydrodynamics code for 3D explosion simulations, Burn code for nucleosythesis post-processing, and Python code written to analyze the output of the post-processing code.

Television is currently in a changing state. There is no longer a singular broadcast format for series to follow. Streaming websites such as Netflix, Hulu, and Amazon Prime now release series in their entirety; this is known as a full-season release (FSR). Viewers are now able to act independently and determine the pace they wish to watch a new FSR series. This not only affects how fans engage in social television discussions on social media, but also changes the previously proposed viewer engagement model. Whereas previous research suggests that fans follow a static linear engagement model consisting of pre-communication, parallel communication, and post communication phases, fans are now able to move freely through viewer engagement phases. This creates a new type of engagement model: The Atomized Engagement Model. As fans move freely through the atomized engagement phases, they choose social media platforms to engage in fandom discussion. Research suggests that although there are distinct types of posts that occur in relation to social television discussions, the platforms used have a direct effect on the content and length of the post.

Description
We hypothesized that recurrent exposure to a temporal discounting task would habitize participants, so that they become insensitive to framing effects. Temporal discounting is a behavioral trend which describes how people discount the value of a reward dependent on the time until receipt. Participants completed a temporal discounting task weekly for five weeks, to promote formation of a habitual decision strategy. Concomitant with this, we expected that people would shift their decision process from a deliberate, goal-oriented approach that is sensitive to changes in reward outcomes and environmental context, to a simplified, automatic approach that minimizes cognitive effort. We expected that this shift in decision strategy would be evident in a reduced influence of contextual effects on choice outcomes. We tested this hypothesis by leveraging two framing effects \u2014 the date/delay effect and the decimal effect. Consistent with our hypothesis, we find that the date/delay effect is significant on week 1, shows significant changes in week 1 to week 5, and is no longer significant on week 5. The results for the decimal effects were not significant. We discuss these results with respect to the cognitive processes that underlie temporal discounting and self-control.

Description
A problem of interest in theoretical physics is the issue of the evaporation of black holes via Hawking radiation subject to a fixed background. We approach this problem by considering an electromagnetic analogue, where we have substituted Hawking radiation with the Schwinger effect. We treat the case of massless QED in 1+1 dimensions with the path integral approach to quantum field theory, and discuss the resulting Feynman diagrams from our analysis. The results from this thesis may be useful to find a version of the Schwinger effect that can be solved exactly and perturbatively, as this version may provide insights to the gravitational problem of Hawking radiation.

Description
Observations of four times ionized iron and nickel (Fe V & Ni V) in the G191-B2B white dwarf spectrum have been used to test for variations in the fine structure constant, α, in the presence of strong gravitational fields. The laboratory wavelengths for these ions were thought to be the cause of inconsistent conclusions regarding the
variation of α as observed through the white dwarf spectrum. This thesis presents 129 revised Fe V wavelengths (1200 Å to 1600 Å) and 161 revised Ni V wavelengths (1200 Å to 1400 Å) with uncertainties of approximately 3 mÅ. A systematic calibration error
is identified in the previous Ni V wavelengths and is corrected in this work. The evaluation of the fine structure variation is significantly improved with the results
found in this thesis.

Description
In fan fiction, fans utilize different elements in an original work and incorporate them into their fanfics; elements such as the characters and setting of an original work are frequently used in fan fiction. A different element is investigated: time travel. The physics behind time travel is not yet understood, so authors have to create their own time travel physics in their works to account for this lack of understanding. Therefore, for fan authors to incorporate time travel into their fanfic, they must study the time travel physics in the original work the same way that characters from an original work are studied. Three original works and three fanfics are examined: the television show My Little Pony: Friendship is Magic and its fanfic "The Fall and Rise of the Alicorn", the Harry Potter book series and its fanfic "Back to the Time of the Unknown", and the webcomic Homestuck and its fanfic "Like a Bug on a Windshield".

Description
The influence of mix design on the structural properties of FAU-type (faujasite) zeolite was studied. Samples were synthesized in a forced convection oven using various proportions of coal fly ash, sodium hydroxide (NaOH), and sodium chloride (NaCl). Three faujasite varieties, labeled X, P and S, were prepared for each mix design. Samples were characterized using Fourier transform infrared (FT-IR) spectroscopy and thermo-gravimetric analysis (TGA). Mercury intrusion porosimetry (MIP) was used to obtain porosity information on the samples. Mechanical strength testing was performed on solid blocks of the zeolite samples prepared in a mold. It was found that the S variety in mix design (iv) had the most desirable balance of porosity and strength for engineering applications.
