Description
Though problem-oriented policing and hot spot policing are both effective modern policing strategies, some critics have argued that the risk of crime displacement can outweigh the returns of hot spot policing, ultimately rendering it inefficacious. However, a growing body of evidence suggests that crime displacement is not only uncommon, but significantly rarer than diffusions of benefits. As diffusion is a desirable side effect of any policing strategy, it follows that police officers should use the phenomenon to their advantage. Using the data and methodologies of a number of hot spot policing studies—especially Koper’s (1995) research on temporal diffusion—this paper proposes a number of simple steps a police department can take to maximize their department’s effectiveness in high-crime areas.

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
This is a composition of information derived from the research conducted to produce each episode of Nefarious. As part of my final thesis project for my undergraduate degrees in criminal justice and forensic psychology, I created a podcast on the topic of true crime with an academic approach titled Nefarious. Each episode of Nefarious examines a particular case in relation to some academic theme learned throughout my educational career at Arizona State University. Episode one examines the life and crimes of Richard Ramirez and different criminological theories that could be used to explain his behavior. Episode two looks at the case of Brock Turner and Chanel Miller and focuses on the larger problem of rape culture in America and sexual assault on college campuses. In episode three the case of the Central Park Five is detailed in relation to false confessions and wrongful convictions within the legal system. Episode four is centered around Kyle Rittenhouse and the use of self-defense as a legal defense in the justice system as well as the political atmosphere surrounding this case. The fifth episode explores three cases of police brutality against racial minorities and the history of police in America. The final episode of Nefarious covers the life and crimes of Jeffrey Dahmer and analyzes such actions from a forensic psychology approach.

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.

Description
The importance of social work lies in the ability of individuals, families, and communities to thrive. It is important to note that social work encompasses a wide range of professions. However, this creative project will examine its different dimensions, specifically within the field of criminal justice. The purpose of this thesis project is to promote social work as a profession and explore its growing impact on the criminal justice system. As part of this effort, it is also intended to dispel the myth that social workers work exclusively in child protection agencies. Viewers will be introduced to exciting opportunities for meaningful change at the emerging intersection of social work and criminal justice, which is becoming increasingly prevalent in American society. This project will also highlight how negative media (news and documentaries like Gabriel Fernandez on Netflix) about social workers employed in the DCS system do not accurately portray current circumstances. This will be accomplished through a short video/documentary-style project that interviews social workers and social service workers employed in the criminal justice field. An interview will consist of questions designed to dispel myths about social workers and promote the diversity of the profession. The purpose of this is to provide an ‘on-the-ground’ perspective of real opportunities in the community, including descriptions of various occupations and the mission of agencies that employ at the cross-section of social work and criminal justice. This is done to enhance the viewers' perception of the field and give them the opportunity to experience real-life situations.
