It is possible that voluntary studies on the effects of divorce fail to capture the perspectives of offspring who may be deterred from volunteering by their negative experiences of the divorce of their parents. This issue of non-response bias would cause researchers to gather unrepresentative samples that ultimately create an unrepresentative picture on the effects of divorce. The problem of non-response bias may also be a possible explanation for why research shows that small differences in psychological problems exist between children of divorce and children from intact families. This study sought to identify if non-response bias compromises the external validity of a sample of college students of divorce. To answer this question we conducted this study through the use of the introductory psychology pre screening study that is administered every semester to introductory psychology students at Arizona State University. We surveyed undergraduate introductory psychology students, all of whom completed a required prescreen survey for research credit. The students who indicated they were from divorced families, or whose parents were “never married and not still together”, were invited to participate in a follow up study to “to understand young adults’ perspectives on their parents’ divorce”. The students who responded to our invitation were compared to the students who did not volunteer in terms of their prescreen data. Volunteers did not differ from non-volunteers on seven out of the ten dependent measures. Volunteers differed from non-volunteers in terms of their closeness to their fathers, in terms of the parents conflict they experienced during the two years before and the two years after their parents permanently separated. Volunteers were more likely to be closer to their fathers and more likely to have experienced more parent conflict than non-volunteers. We are unaware of any studies on the subject of divorce that have had a similar opportunity to address the issue of non-response bias and its effects on the external validity of a college sample of divorce. This study should be replicated to determine the reliability of the results.

Description
As structural engineers in practice continue to improve their methods and advance their analysis and design techniques through the use of new technology, how should structural engineering education programs evolve as well to match the increasing complexity of the industry? This thesis serves to analyze the many differing opinions and techniques on modernizing structural engineering education programs through a literature review on the content put out by active structural engineering education reform committees, articles and publications by well-known educators and practitioners, and a series of interviews conducted with key individuals specifically for this project. According to the opinions analyzed in this paper, structural engineering education should be a 5-year program that ends with a master’s degree, so that students obtain enough necessary knowledge to begin their positions as structural engineers. Firms would rather continue the education of new-hires themselves after this time than to wait and pay more for students to finish longer graduate-type programs. Computer programs should be implemented further into education programs, and would be most productive not as a replacement to hand-calculation methods, but as a supplement. Students should be tasked with writing codes, so that they are required to implement these calculations into computer programs themselves, and use classical methods to verify their answers. In this way, engineering programs will be creating critical thinkers who can adapt to any new structural analysis and design programs, and not just be training students on current programs that will become obsolete with time. It is the responsibility of educators to educate current staff on how to implement these coding methods seamlessly into education as a supplement to hand calculation methods. Students will be able to learn what is behind commercial coding software, develop their hand-calculation skills through code verification, and focus more on the ever-important modeling and interpretation phases of problem solving. Practitioners will have the responsibility of not expecting students to graduate with knowledge of specific software programs, but instead recruiting students who showcase critical thinking skills and understand the backbone of these programs. They will continue the education of recent graduates themselves, providing them with real-world experience that they cannot receive in school while training them to use company-specific analysis and design software.

Description
Oxic beds containing basic oxygen furnace slag were evaluated as potential post-treatment method for sulfate reducing bioreactor (SRB) treatment of acid rock drainage. SRB effluent was pumped into BOF slag/sand leach beds, also known as oxic slag beds (OSBs), at various flow rates. OSB influent versus effluent concentrations of dissolved metals (specifically magnesium and manganese) and water quality parameters (pH, dissolved oxygen concentration, and conductivity) were compared. The OSBs increased the pH of the SRB effluents from 6.2–6.7 to 7.5–8.3. Dissolved oxygen concentration increased from 2-4 mg L^(-1) to approximately 8 mg L^(-1). Conductivity remained similar, with some effluent values being less than influent. Manganese concentration was observed to be reduced through OSB post-treatment by an average of 8.2% reduction and a maximum of 23 % reduction. Magnesium was not reduced during OSB post-treatment. Other metal concentrations changes were analyzed. Recommendations the design of OSBs for future studies were made, and a proposed design was configured.

Description
Terrestrial crude oil spills compromise a soil’s ability to provide ecosystem services by inhibiting plant life and threatening groundwater integrity. Ozone gas, a powerful oxidant, shows promise to aid in soil recovery by degrading petroleum hydrocarbons into more bioavailable and biodegradable chemicals. However, previous research has shown that ozone can change the soil pH and create harmful organic compounds.
The research objective was to determine the short-term ecological toxicity of ozonation byproducts on seed germination of three distinct plant types (radish, lettuce, and grass) compared to untreated and uncontaminated soils. We hypothesize that the reduction of heavy hydrocarbon contamination in soil by ozone application will provide more suitable habitat for the germinating seeds. The effect of ozone treatment on seed germination and seedling quality was measured using ASTM standards for early seedling growth in conjunction with a gradient of potting soil amendments. Ozonation parameters were measured using established methods and include total petroleum hydrocarbons (TPH), dissolved organic carbon (DOC), and pH.
This study demonstrated the TPH levels fall up to 22% with ozonation, suggesting TPH removal is related to the amount of ozone delivered as opposed to the type of crude oil present. The DOC values increase comparably across crude oil types as the ozonation dose increases (from a background level of 0.25 g to 6.2 g/kg dry soil at the highest ozone level), suggesting that DOC production is directly related to the amount of ozone, not crude oil type. While ozonation reduced the mass of heavy hydrocarbons in the soil, it increased the amount of ozonation byproducts in the soil. For the three types of seeds used in the study, these changes in concentrations of TPH and DOC affected the species differently; however, no seed type showed improved germination after ozone treatment. Thus, ozone treatment by itself had a negative impact on germination potential.
Future research should focus on the effects of post-ozonation, long-term bioremediation on eco-toxicity. By helping define the eco-toxicity of ozonation techniques, this research can improve upon previously established ozone techniques for petroleum remediation and provide economic and environmental benefits when used for soil treatment.

Description
Volunteering can lead to many positive outcomes on individuals in terms of social, psychological, and professional development. This study sought to understand the process and mindset of volunteers and how their experience affects attitudes towards environment. The purpose of this study is to analyze the attitude change of volunteers toward the environment, culture, and community after volunteering at a community of a background different than theirs. In this study, the volunteer setting is in Shonto, a Native American community in the Navajo Nation, Arizona. This study utilized a qualitative research approach. A total of 12 participants were interviewed in this study. All participants were members of Engineers Without Borders (EWB) at Arizona State University and have traveled to Shonto. Questions were asked to participants about their experiences with EWB and their volunteering experiences in Shonto. The main findings were categorized into four themes: 1) motivations; 2) preconceived perceptions and exposure; 3) collaboration and connection; and 4) commonality and reflection. The findings can be described as a process that participants go through in their entire volunteering experience. The first two themes occur before individuals volunteer and the last two themes occur after. First, individuals develop certain motivations to volunteer. Then, the preconceived perceptions of individuals were analyzed, and it was presumed that these perceptions were a result of their upbringing and exposure, or lack thereof, to the community they volunteer at. The last two themes occur after the individuals have volunteered. Individuals are able to collaborate and form a connection with the community, which influences their awareness and their ability to reflect on their experiences. These last two themes are important because they indicate the change of perceptions that volunteers perceive. These findings connect the motivations that volunteers have all the way to their attitude changes after volunteering. Further, findings demonstrate that the preconceived perceptions are influenced by an individual’s upbringing or exposure, but these misconceptions are changed after volunteering experience, which supports contact theory. Through these findings the study contributes to the existing literature on voluntourism. This study is applicable to organizations and tour operators who offer volunteer tourism programs and work with communities of different backgrounds. It can provide individuals an insight to other volunteering experiences.

Description
Family influences are known predictors of adolescent health and well-being trajectories, yet little research has investigated how adolescents’ orientation to family may be associated with their physiological stress responses. Influenced by the strength-based approach to culture, this study evaluated 418 Hispanic adolescents' familism values and perceived life stress in family, school, and peer domains to investigate prospective associations with hypothalamic-pituitary-adrenal axis stress responses to the Group Public Speaking Task for Adolescents (GPST-A). Prior growth-mixture modeling on this sample revealed a five-class solution of cortisol responding to the GPST-A that was used here as the dependent variable: one class showed a more pronounced pattern of reactivity, potentially indicative of hyper-responsivity to the stress task; two classes showed evidence of a low to moderate cortisol response, potentially indicative of an adaptive physiological response to the challenge; and two classes showed patterns of non-responsivity, potentially indicative of hypo-responsivity. Results demonstrate that the role of familism is nuanced in the context of stressors, potentially offering both promotive and risk-amplifying effects for the physiological stress response system. This study offered several novel findings in the relation between cultural factors, salient stressors of adolescence, and HPA activity.

Description
An existing house is outdated and in need of a renovation. The kitchen, living room, bar and dining room are currently all closed off from one another creating four separate spaces. The goal is to recreate the main floor into an open concept space, that is great for entertaining, and being with family and friends. This Thesis/Creative Project deals in the area of structural redesign, aesthetics, client relations and budget tracking. To do this effectively, Revit, AutoCAD, RISA 3D and Excel will all be used to complete various elements of the project. In order to open the space a structural analysis needs to be done to ensure the structural integrity of the home remains solid. If structural walls are being removed the forces being exerted on those walls will need to be redistributed. This will require a redesign of the structural members to ensure the forces are supported. Once the walls are down the area can be redesigned to ensure function and usability. Every inch of the space needs to be optimized to ensure the most efficient use of space. The storage will also need to be taken into consideration because there will be storage loss when removing walls. The space will need to look aesthetically pleasing and keep in theme with the country cabin feel of the home. The Client’s will be involved in every step of the process to ensure they are satisfied with the varying design. While redesigning the area there is a strict budget that was set by the Clients, and every step of the designing process needs to take into consideration the cost. Once the successful completion of the project is accomplished, the Clients, will have the ability to take the plans and complete the renovation on the house.

Description
This thesis is part of a larger research project, conducted by Elizabeth Stallings Young, which aims to improve understanding about the factors controlling the process of MIDP and the interaction between the biochemical reactions and the hydrological properties of soils treated with MIDP. Microbially Induced Desaturation and Precipitation (MIDP) is a bio-geotechnical process by which biogenic gas production and calcite mineral bio-cementation are induced in the pore space between the soil particles, which can mitigate earthquake induced liquefaction (Kavazanjian et al. 2015). In this process substrates are injected which stimulate indigenous nitrate reducing bacteria to produce nitrogen and carbon dioxide gas, while precipitating calcium carbonate minerals. The biogenic gas production has been shown to dampen pore pressure build up under dynamic loading conditions and significantly increase liquefaction resistance (Okamura and Soga 2006), while the precipitation of calcium carbonate minerals cements adjacent granular particles together. The objective of this thesis was to analyze the recorded pore pressure development as a result of biogenic gas formation and migration, over the entire two-dimensional flow field, by generating dynamic pressure contour plots, using MATLAB and ImageJ software. The experiment was run in a mesoscale tank that was approximately 114 cm tall, 114 cm wide and 5.25 cm thick. Substrate was flushed through the soil body and the denitrifying reaction occurred, producing gas and correspondingly, pressure. The pressure across the tank was recorded with pore pressure sensors and was loaded into a datalogger. This time sensitive data file was loaded into a MATLAB script, MIDPCountourGen.m, to create pressure contours for the tank. The results from this thesis include the creation of MIDPContourGen.m and a corresponding How-To Guide and pore pressure contours for the F60 tank. This thesis concluded that the MIDP reaction takes a relatively short amount of time and that the residual pressure in the tank after the water flush on day 17 offers a proof of effect of the MIDP reaction.

Description
School racial/ethnic diversity has been linked to positive developmental outcomes for youth in early adolescence (Graham, 2018). The purpose of this study was to examine whether school diversity and co-ethnic representation was associated with academic outcomes of children in middle childhood. Given mixed findings in previous research, this study explored whether the effects of school diversity and co-ethnic representation on academic achievement were moderated by the ethnicity of the individual in a sample of twins in middle childhood (N=485; Mage= 8 8.36 years, SD = .62). Parent-report, teacher-report, and objective ratings of academic outcomes were used. Results indicated that school diversity was positively and significantly associated with teacher reported achievement (b = .80, p < .05) across the full sample. Moderation analyses suggest that greater school diversity was associated with lower parent-reported and objective academic scores for European American youth, but higher teacher-reported and objective academic outcomes for ethnic minority youth. Results indicated that, across the full sample, co-ethnic representation was significantly and negatively associated with one measure of objective academic outcomes (b = -7.99, p < .05). Contrary to hypotheses, greater co-ethnic representation was associated with better teacher-reported and objective academic outcomes for European American youth, but lower objective academic outcomes for ethnic minority children. Findings demonstrate that the ethnic composition of schools are associated with academic outcomes of children in middle childhood, but findings vary by measurement of diversity (i.e., diversity index vs. co-ethnic representation and by the child’s own race/ethnicity.
