Description
With the projected population growth, the need to produce higher agricultural yield to meet projected demand is hindered by water scarcity. Out of many the approaches that could be implemented to meet the water gap, intensification of agriculture through adoption of advanced agricultural irrigation techniques is the focus for this research. Current high water consumption by agricultural sector in Arizona is due to historical dominance in the state economy and established water rights. Efficiency gained in agricultural water use in Arizona has the most potential to reduce the overall water consumption. This research studies the agricultural sector and water management of several counties in Arizona (Maricopa, Pinal, and Yuma). Several research approaches are employed: modeling of agricultural technology adoption using replicator dynamics, interview with water managers and farmers, and Arizona water management law and history review. Using systems thinking, the components of the local farming environment are documented through socio-ecological system/robustness lenses. The replicator dynamics model is employed to evaluate possible conditions in which water efficient agricultural irrigation systems proliferate. The evaluation of conditions that promote the shift towards advanced irrigation technology is conducted through a combination of literature review, interview data, and model analysis. Systematic shift from the currently dominant flood irrigation toward a more water efficient irrigation technologies could be attributed to the followings: the increase in advanced irrigation technology yield efficiency; the reduction of advanced irrigation technology implementation and maintenance cost; the change in growing higher value crop; and the change in growing/harvesting time where there is less competition from other states. Insights learned will further the knowledge useful for this arid state's agricultural policy decision making that will both adhere to the water management goals and meet the projected food production and demand gap.

Description
Previous research has indicated that certain breeds of dogs stay longer in shelters than others; however exactly how breed perception and identification influences potential adopters' decisions remains unclear. Current dog breed identification practices in animal shelters are often based upon information supplied by the relinquishing owner, or staff determination based on the dog's phenotype. However discrepancies have been found between breed identification as typically assessed by welfare agencies and the outcome of DNA analysis. In Study 1, the perceived behavioral and adoptability characteristics of a pit-bull-type dog were compared with those of a Labrador Retriever and Border Collie. How the addition of a human handler influenced those perceptions was also assessed. In Study 2, lengths of stay and perceived attractiveness of dogs that were labeled as pit bull breeds to dogs that were phenotypically similar but were labeled as another breed at an animal shelter were compared. The latter dogs were called "lookalikes." In Study 3, perceived attractiveness in video recordings of pit-bull-type dogs and lookalikes with and without breed labels were compared. Lastly, data from an animal shelter that ceased applying breed labeling on kennels was analyzed, and lengths of stay and outcomes for all dog breeds, including pit bulls, before and after the change in labeling practice were compared. In total, these findings suggest that breed labeling influences potential adopters' perceptions and decision-making. Given the inherent complexity of breed assignment based on morphology coupled with negative breed perceptions, removing breed labels is a relatively low-cost strategy that will likely improve outcomes for dogs in animal shelters.

Description
Each year, nearly three million dogs will enter one of over 13,000 animal shelters in the United States. The purpose of this dissertation is to better understand how breed identity and dog welfare in the shelter, in addition to post-adoption and fostering interventions out of the shelter, can contribute to the betterment of dog lives. In Chapter 2, I conducted the largest sampling of shelter dogs’ breed identities to-date to determine their breed heritage and compare shelter breed assignment by staff as determined by visual appearance to that of genetic testing. In Chapter 4, I examined the efficacy of a post-adoption intervention intended to reduce returns by encouraging physical activity between adopters and their dogs. In Chapter 6, I examined the effects of brief stays in a foster home on the urinary cortisol: creatinine ratios of dogs awaiting adoption compared to ratios collected before or after their stays; and in Chapter 7, I characterized the relationships between multiple physiological, health, and cognitive measures and the in-kennel behavior of shelter dogs.
Four suggestions from the findings of this dissertation that will likely better the lives of dogs living in animal shelters are: 1) Shelter dog breed heritage is complex and visually identifying multiple breeds in a mixed breed dog is difficult at best. Shelters should instead focus on communicating the morphology and behavior of the dogs in their care to best support adopters. 2) While encouraging walking did not influence owner behavior, adopters who reported higher obligation and self-efficacy in dog walking were more active with their dogs. Thus, post-adoption interventions that can effectively target owner perceptions of obligation and self-efficacy may be more successful in changing behavior. 3) Temporary fostering is an impactful intervention that reduces stress for dogs awaiting adoption; however addressing stressors present at shelters that are likely contributing to higher stress responding is also needed. 4) It is possible to predict the internal stress responding of shelter dogs by observing their overt, in-kennel behavior, and this study is a first step in assessing and improving the welfare of dogs living in animal shelters.

Description
Purpose: The purpose of this study was to identify the experiences of mothers who had adopted children from Pleven, Bulgaria, with an added focus on their experiences of interactions with healthcare personnel. Design: An interpretive phenomenological study method was used to interview 5 mothers of children who had been adopted from Bulgaria. The interviews were transcribed and analyzed for thematic material. Findings: All except for one of the children had underlying physical congenital problems and all of the children were found to be severely damaged by institutional neglect. All of the mothers had other biological children. The themes that emerged included logistical challenges, priority of family relationships, emotional impact, and amazing improvement. The mothers identified two key aspects of their interactions with medical personnel: listening and respect from healthcare individuals and the importance of taking their child's unique history and situation into account. Conclusions: For mothers who had adopted children from Pleven, Bulgaria, life was not simple. These mothers found life following their adoptions both difficult and rewarding. These mothers desired that others listen to their stories in order to help improve healthcare interactions that they face daily, to encourage others to adopt children from the institution in Pleven, and to stop the abuses occurring at the institution.

Description
International adoption is always changing, influenced by global politics and social norms. This thesis looks specifically at Russian and Eastern European adoption and reasons why parents choose these countries from which to adopt. I then interviewed eight people who had either adopted or been adopted from this region to examine the idea of "culture-keeping" and what factors influence a parent's decision to encourage culture-keeping or not.

Description
This memoir is organized into three parts, each based on a geographic location where I have lived that has contributed to my self-growth the most. The first part, South Korea, analyzes the history of South Korea, as well as its relationship of international adoptions with the United States through my personal adoption story. The second part is focused on the sixteen years I spent growing up in Utah. From my early years in school, sports, part-time jobs, graduating from high school and my life as a member of the Church of Jesus Christ of Latter-Day Saints, this section will showcase the difficulties of growing up in a town where I never fit in. The third and final part deals with the past three years of living in Arizona and attending college.
Even though writing this memoir is incredibly personal to myself, that does not discourage others from gaining something from reading this. I am not the first Asian American, ex-Mormon, college student or adopted individual who writes about their life and I most certainly will not be the last. If anyone is somewhat interested in any of the topics I am going to be writing about, then they can read this memoir and learn something. If not, then they can at least enjoy the stories and hopefully something I went through will put a smile on their face.

Description
As science has progressed, sleep deficiency has been discovered to be associated with declines in both mental and physical health, and similarly, sleep deficiency has been noted as a public safety concern with 20 percent of motor vehicle crashes linked to driving while drowsy. The National Sleep Foundation has identified that 62 percent of Americans do nothing to address their sleep deficiency, and with a society that normalizes coping mechanisms such as napping and caffeine consumption, it is easy to see why nothing has been done to resolve this issue. Nevertheless, with sleep technology falling in the hands of more and more Americans this thesis aims to explore how these technologies are being adopted and how the introduction of sleep-oriented features for established products may lead to more sleep conscious consumers.
