Doctor of Philosophy / Department of Apparel, Textiles, and Interior Design / Melody L. A. LeHew / The relationship between knowledge, attitudes and behavior has been a subject of interest for researchers for several decades in various fields of study. However, an inconsistency has been found from one study to another with literature showing inconclusive and inconsistent results regarding the relationship between knowledge, attitudes and behavior in general and purchase of eco-conscious apparel in particular. Literature also found perceived characteristics of innovation (PCI) to significantly influencing innovation adoption. However, research investigating the influence of eco-conscious apparel knowledge (EAK) and eco-conscious apparel attitudes (EAA) on intention to purchase eco-conscious apparel (IPEA) that includes PCI has not been conducted in any previously published studies. Therefore, the purpose of this study was to investigate the influential relationship between EAK-EAA-IPEA to understand if including PCI strengthens the inconsistent link between knowledge, attitudes and behavior as well as enhances the predictability of IPEA. The model of stages in the innovation-decision process developed by Roger’s (1983) in the diffusion of innovation theory was used as a theoretical framework for developing the model of innovation-decision process for eco-conscious apparel. Specifically, the three product characteristics used in this current study were based on the PCI (i.e., complexity, compatibility and relative advantage) explained by Rogers (1983) in his model. Two objectives were developed and tested using six research questions and pertinent hypotheses. The research relied on quantitative analysis of responses from 592 respondents to an online survey with eco-conscious knowledge, attitude and behavior questions pertaining eco-conscious apparel products. Hierarchical regression analysis, t-test and correlation analysis reveal that, inclusion of PCI significantly strengthened relationship between EAK-EAA-IPEA and also enhanced the predictability of IPEA; the ability to predict IPEA as well as strength of the link between EAK-EAA-IPEA was greater when more information was provided about eco-conscious apparel than less information; respondents have limited EAK; EAK was not a good predictor of IPEA; EAA was found to significantly predict IPEA; highly innovative respondents perceive eco-conscious apparel less complex and highly compatible and are more likely to purchase eco-conscious apparel; all three PCI were found to significantly predict IPEA; demographic variables were found to be related to only certain variables in this study.

Master of Science / Family Studies and Human Services / Karen S. Myers-Bowman / Single parenting has become a part of American society, yet it seems that through stereotyping and shaming these parents are looked down upon. Often times, single parents do not have the same resources as two parent homes, but single parents can still be effective and raise well-rounded children. This is a qualitative study that sought to provide a different perspective of single never-married parents by interviewing their young adult children. This study focused on the experiences of the young adult children and used Family Stress Theory to help understand and capture specific moments in their lives.

Master of Science / Department of Grain Science and Industry / Jon Faubion / Whole wheat flour has become a popular ingredient in baked goods. Consumers are seeking the added benefits of consuming healthy phytochemicals and bioactive compounds. As the demand for wholemeal flour increases it is important to understand the factors contributing to changes in whole wheat flour breadmaking quality as a function of both wheat and flour age. In wholemeal flour, the lipid composition appears to be a factor causing variable baking quality. Changes that occur in both freshly harvested wheat and milled flour can cause variations in baking quality. Bakers’ attempts to adjust formulations and processes are often unsuccessful. The objective of this study was to determine the effects of aging both new crop wheat and freshly milled flour at 2 different temperatures on baking quality and glycolipid composition. This study aged freshly harvested Overley hard red winter wheat at RT (23˚C) and FZ (-26˚C) for 8, 50, and 91 days before milling. Whole wheat flour baking and lipid extraction studies were performed incrementally over 31 days of flour storage after each milling. Glycolipid structure and amounts were measured using automated electrospray ionization-tandem mass spectrometry. The glycolipids analyzed in this study were DGDG (digalactosyldiglycerol), MGDG (monogalactosylmonoglycerol), MGMG (monogalactosylmonoglycerol), and DGMG (digalactosylmonoglycerol). Both the wheat and flour stored at -26˚C produced larger mean loaf volumes than did the 23˚C treatment for all 3 wheat ages. The FZ and RT DGDG:MGDG ratios were similar over both wheat and flour age so changes to the glycolipid fraction did not appear to be the cause of the significant difference between volumes of bread baked from samples stored at RT and FZ. There was limited change in mean volume over flour age except for an increase at the FZ 91 day point. The DGDG:MGDG ratios were generally unchanged over flour age. Loaf volumes were the same over wheat age except for an unexpected drop during the 50 day wheat study. The corresponding DGDG:MGDG ratios did not show any significant differences over wheat age. The FZ storage temperature might be inhibiting some biochemical change not affecting the glycolipids, leading to higher volumes than the RT storage treatment.

Doctor of Philosophy / Family Studies and Human Services / Duane W. Crawford Jr / Farrell J. Webb / This investigation sought to examine the role of acculturation and generational theory and influenced social and cultural practices among Saudi Arabian students who were currently residing in the United States. Theoretically, it sought to answers questions that help determine how Americanization—the adaptation and acculturation of a visiting culture to absorb and incorporate the host culture into their lives, customs, and social practices, and in this case savings behavior. A comprehensive model was developed to test the idea that living in America can and does have an influence on social and cultural practices. What was of interest in this study was whether or not these same influences could have an impact on particular cultural practices, in this case how people felt about, reacted to, and addressed the concept of savings—the stockpiling of funds for future needs. Information was gathered from a sample of over 500 Saudi Arabian students living in the United States. The model as structured was tested using SEM analytic techniques in an effort to fully explore and expose the nuanced and subtle differences among the respondents. The concept of savings behavior being influenced by Americanization as originally discussed was not substantiated by the model even though some of the indicators were within expected parameters (χ² = 217.241, p < .001; CFI = 0.839, TLI = 0.732, RMSEA = 0.034). Despite the general problems the overall model revealed that at least 17% of what was termed as savings behavior could be explained by the model. The study still retained its value because it has made inroads into an area that has not yet been explored. Future investigations should take care to find better ways to incorporate some of the cultural elements of savings behavior directly into the instrument based on the perspective of their test populations rather than assume value in and use instruments tested and normed with US samples.
