Description
An increasing number of military veterans are enrolling in college, primarily due to the Post-9/11 GI Bill, which provides educational benefits to veterans who served on active duty since September 11, 2001. With rigorous training, active combat situations, and exposure to unexpected situations, the veteran population is at a higher risk for traumatic brain injury (TBI), Post Traumatic Stress Disorder (PTSD), and depression. All of these conditions are associated with cognitive consequences, including attention deficits, working memory problems, and episodic memory impairments. Some conditions, particularly mild TBI, are not diagnosed or treated until long after the injury when the person realizes they have cognitive difficulties. Even mild cognitive problems can hinder learning in an academic setting, but there is little data on the frequency and severity of cognitive deficits in veteran college students. The current study examines self-reported cognitive symptoms in veteran students compared to civilian students and how those symptoms relate to service-related conditions. A better understanding of the pattern of self-reported symptoms will help researchers and clinicians determine the veterans who are at higher risk for cognitive and academic difficulties.

Description
As the United States' military presences in Afghanistan and Iraq are being minimized, an increasing number of veterans are transitioning from the military to pursue higher education opportunities. Due to the military's organizational characteristics, socialization procedures, and performance requirements, this population of students likely faces unique barriers to success in traditional models of higher education. The increase of this unique population necessitates research to evaluate their educationally related social and relational needs so that institutions of higher education will be better able to assist in achieving their academic goals. The student-teacher relationship is a key predictor in students' academic success (Yoon, J. S., 2002). Using survey research, this project examines veteran students' perceptions of their relationships with instructors, characteristics of the organization, communication apprehension with professors and peers, and perceived self-esteem. With the assistance of the Pat Tillman Veterans Center at Arizona State University, approximately 3800 veteran students, in both undergraduate and graduate programs, were invited to participate in the research. The study identified significant relationships between a veteran-student's length of time since separating from military service, their feelings of success as a student, self-esteem, and apprehension of communication with professors. There was also a significant relationships on length of military service, self-esteem, and apprehension of communication with professors.

Description
Through oral history and interviewing Veterans, I explored what military service looks like, and how diverse different service member's experiences are. I conducted comprehensive interviews with four Veterans: three Marines and an Army Medic. Each interview covered basic questions centered on enlistment, service/deployment, and the transition back into civilian life. After the interviews, I wrote interview summaries to provide a written account of the Veteran's experience. I also created a video compilation of the four veterans and their responses to certain questions. The objective of my project was to make the Veterans' experiences accessible to people without a military background.

Description
The purpose of this essay is to determine how the narratives of veterans who served in combat roles during the Vietnam War have affected how historians have written about the war. First, this project will briefly cover the history of the general public’s view of the war and it’s veterans, looking at how feelings towards Vietnam War veterans have shifted over the past fifty years. Next, this project will analyze two books about the Vietnam War that focus primarily on the veteran experience, rather than on the internal politics of the United States and Vietnam or on the successes or failures of battle, and determine the extent to which these books contribute to public understanding of the war. This essay will then determine the role memory plays in crafting these narratives and how historians have an obligation to include or at least consider the complex perspectives of veterans and their families when they write on topics as controversial as warfare.

Description
An increasing number of veterans are transitioning from military service to college. Critical to academic success is the process of decision-making, which previous research has found to be influenced by a variety of factors including anxiety and working memory (WM). Many service-related conditions often influence anxiety and WM, and given the high prevalence of these conditions among veterans, the present study aimed to analyze the effects of working memory and anxiety on decision-making behavior in U.S. Military Veterans. Participants completed a large test battery including tasks assessing WM skills (Symmetry Span Task), anxiety (Beck Anxiety Inventory), and decision-making (Iowa Gambling Task). The study results indicated that WM and anxiety both play roles in decision-making performance in young military veterans. High anxiety is related to increased avoidance of adverse outcomes in decision-making for U.S. Military Veterans, while lower working memory span is associated with greater risk-taking behavior. This study provides both functional and clinical implications into areas of possible intervention that need to be assessed in military veterans, as well as modifications to these assessments that need to be made in order to appropriately measure decision-making behavior. Future work will be done in order to more effectively analyze the adverse impacts of service-related conditions and the ways in which intervention can be implemented in order to minimize these effects.

This thesis looks at a short-term solution to the truck driver shortage: transitioning U.S. military veterans into truck driver roles. Due to the adoption of self-driving trucks, the shortage is projected to end in 2022; however, freight companies may not be able to keep up with growing freight volumes until then. In the meantime, providing commercial driver's license (CDL) training on military bases has the potential to alleviate the shortage and veteran unemployment. A number of journal articles were read and interviews were conducted to determine the practicality of this solution. This thesis includes those findings and a number of considerations that should be made before implementing it.

Description
Currently conventional Subtitle D landfills are the primary means of disposing of our waste in the United States. While this method of waste disposal aims at protecting the environment, it does so through the use of liners and caps that effectively freeze the breakdown of waste. Because this method can keep landfills active, and thus a potential groundwater threat for over a hundred years, I take an in depth look at the ability of bioreactor landfills to quickly stabilize waste. In the thesis I detail the current state of bioreactor landfill technologies, assessing the pros and cons of anaerobic and aerobic bioreactor technologies. Finally, with an industrial perspective, I conclude that moving on to bioreactor landfills as an alternative isn't as simple as it may first appear, and that it is a contextually specific solution that must be further refined before replacing current landfills.

Description
The following is a review of the literature on Equine Assisted Psychotherapy (EAP) as a potential treatment for US service members with Post-Traumatic Stress Disorder(PTSD). EAP is a relatively new and undeclared psychotherapeutic technique that presents limitless opportunities for holistic growth in patients who have Post-Traumatic Stress Disorder (PTSD) who have not achieved an improvement in their quality of life as a result of other conventional treatments. Due to its heterogenous nature, PTSD directly dismantles the brain’s reward circuitry pathway, altering the individual’s capacity for emotional resolution. For US veterans suffering from PTSD who have not received palpable improvements through traditional talk therapies, EAP is a treatment for emotional vulnerability and communal reintegration when used in conjunction with techniques of attachment theory and cognitive-behavioral theory. Previous studies show an uptick in interpersonal trust and an alleviation of maladaptive defensive mechanisms set in place by the individual to protect the psyche. Research is indicative of an alleviation in overall symptomatology with an emphasis in the rehearsal of therapeutic strategies within interpersonal relationships to rehabilitate social engagement and cognition. Due to the lack of foundational acceptance of EAP thus far as a treatment for PTSD, it is challenging to ascertain a marginalized understanding of the holistic effects of EAP on PTSD as a stand alone psychotherapeutic treatment.

Description
The thesis looks into the sacrifices of first responders and veterans and how the differences between these people of service are transcended by said sacrifices, allowing them to better empathize and understand what one another had gone through. The thesis also looks at this understanding of sacrifices among people of service, and how such an understanding can be used by the public to better understand issues that affect veterans and first responders after and during their service.

Characterization and Manipulation of Microbiomes From Arid Landfills for Improved Methane Production
Description
Environmentally harmful byproducts from solid waste’s decomposition, including methane (CH4) emissions, are managed through standardized landfill engineering and gas-capture mechanisms. Yet only a limited number of studies have analyzed the development and composition of Bacteria and Archaea involved in CH4 production from landfills. The objectives of this research were to compare microbiomes and bioactivity from CH4-producing communities in contrasting spatial areas of arid landfills and to tests a new technology to biostimulate CH4 production (methanogenesis) from solid waste under dynamic environmental conditions controlled in the laboratory. My hypothesis was that the diversity and abundance of methanogenic Archaea in municipal solid waste (MSW), or its leachate, play an important role on CH4 production partially attributed to the group’s wide hydrogen (H2) consumption capabilities. I tested this hypothesis by conducting complementary field observations and laboratory experiments. I describe niches of methanogenic Archaea in MSW leachate across defined areas within a single landfill, while demonstrating functional H2-dependent activity. To alleviate limited H2 bioavailability encountered in-situ, I present biostimulant feasibility and proof-of-concepts studies through the amendment of zero valent metals (ZVMs). My results demonstrate that older-aged MSW was minimally biostimulated for greater CH4 production relative to a control when exposed to iron (Fe0) or manganese (Mn0), due to highly discernable traits of soluble carbon, nitrogen, and unidentified fluorophores found in water extracts between young and old aged, starting MSW. Acetate and inhibitory H2 partial pressures accumulated in microcosms containing old-aged MSW. In a final experiment, repeated amendments of ZVMs to MSW in a 600 day mesocosm experiment mediated significantly higher CH4 concentrations and yields during the first of three ZVM injections. Fe0 and Mn0 experimental treatments at mesocosm-scale also highlighted accelerated development of seemingly important, but elusive Archaea including Methanobacteriaceae, a methane-producing family that is found in diverse environments. Also, prokaryotic classes including Candidatus Bathyarchaeota, an uncultured group commonly found in carbon-rich ecosystems, and Clostridia; All three taxa I identified as highly predictive in the time-dependent progression of MSW decomposition. Altogether, my experiments demonstrate the importance of H2 bioavailability on CH4 production and the consistent development of Methanobacteriaceae in productive MSW microbiomes.
