Description
This research paper aims to analyze the intricacies of the Elementary and Secondary Education Act (ESEA) as well as its reauthorizations, primarily No Child Left Behind (NCLB) with a brief look at the Every Student Succeeds Act (ESSA). Most attention will be placed on Title I of each piece of legislation. Accompanying the analysis will be insight and data examining the varied levels of success for each piece of legislation aimed at minimizing the achievement gap. The data will highlight graduation rates, test scores, dropout rates, adult literacy rates, school enrollment, etc. The research paper will analyze these items on a national scale, then it will direct its attention to Arizona schools. Charter schools will not be analyzed within the scope of this research paper. In exploring these details in terms of a specific state since ESEA's inception, the research paper hopes to better examine the effects of ESEA and perhaps suggest parallels to states nationwide. Since there are so many diverse factors in determining student and school success, it would be unwise to make concrete claims about these figures and whether they prove ESEA was a success or failure. However, the purpose of providing this data is to suggest possible relationships between these federal initiatives and student success. Furthermore, as a prior student and current teacher at a Title I school in Arizona, the author acknowledges that there is potential for bias and the perspective provided in this research paper may differ from that of the reader.

Description
Flora Thew Elementary School is a Title I elementary school in the Tempe Elementary School District. The student body is predominantly Hispanic with an additional large portion of African American students, all coming from low-income backgrounds. The purpose of this project was to investigate the efficacy of American education in these groups of students as well as a personal analysis of the organization, Arizona Mentor Society, that serves to promote student success. The investigation found that while the American education system already fails these students in many ways, the elementary school itself propagates this failure in a faculty body that is unfamiliar with the culture of their student body. Solutions to this problem would include the diversification of the teacher workforce, more strict but inclusive training of educators, and changes in the assessment of these students.

Description
According to the National Center for Education Statistics, Title I \u2014 also known as "Improving the Academic Achievement of the Disadvantaged," is a "[federal] program [that] provides financial assistance through state educational agencies (SEAs) to local educational agencies (LEAs) and public schools with high numbers or percentages of poor children to help ensure that all children meet challenging state academic content and student academic achievement standards," (NCES, 2016.) Title I has existed since the Elementary and Secondary Education Act (ESEA) of 1965, and continues to be reauthorized; most recently, Title I was included in the Every Student Succeeds Act (ESSA) of 2015, (Education Week, 2015). Although Title I's structure has remained much the same over the years, the education market has not, which impacts Title I's future. For example, the number of public and state-accredited schools benefiting from Title I is growing, mainly because of concerns about an increasing number of at-risk youth struggling to meet state and federal academic standards every year. In order to support this growing need, the Title I budget increases year-to-year (U.S. Department of Education, 2004). Furthermore, the Title I program is often criticized based on its effectiveness in assisting LEAs to elevate at-risk youth to meet U.S. academic standards. Because of Title I's sheer size, being the largest federal fund to K-12 education, one can critique Title I's effectiveness in a few ways. For example, school choice institutions, experimental programs, and policies often challenge Title I's formula structure. School choice essentially encourages a parent and/or child to choose the academic institution they wish to affiliate with (Sunderman, 2014). That said, some school choice entities critique the distribution of Title I, because youth that benefit from certain Title I services usually attend poor and/or underperforming schools \u2014 which often lack resources and K-12, Title I Education: School Choice Institutions, Experimental Programs, and Policies 5 educational opportunities - hence school choice seeks to shift the distribution of Title I funds away from poor schools and more towards the individual student to decide their school of choice, (Sunderman, 2014). This thesis reviews the research on Title I's structure, affiliated school choice institutions, experimental programs, and polices; the validity of the underlying assumptions of the school choice critique of Title I; in addition, a school choice policy idea is proposed by the author, which is a more feasible alternative to the ineffective Title I Portability proposal.

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.

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
Zero-Valent Metals (ZVM) are highly reactive materials and have been proved to be effective in contaminant reduction in soils and groundwater remediation. In fact, zero-Valent Iron (ZVI) has proven to be very effective in removing, particularly chlorinated organics, heavy metals, and odorous sulfides. Addition of ZVI has also been proved in enhancing the methane gas generation in anaerobic digestion of activated sludge. However, no studies have been conducted regarding the effect of ZVM stimulation to Municipal Solid Waste (MSW) degradation. Therefore, a collaborative study was developed to manipulate microbial activity in the landfill bioreactors to favor methane production by adding ZVMs. This study focuses on evaluating the effects of added ZVM on the leachate generated from replicated lab scale landfill bioreactors. The specific objective was to investigate the effects of ZVMs addition on the organic and inorganic pollutants in leachate. The hypothesis here evaluated was that adding ZVM including ZVI and Zero Valent Manganese (ZVMn) will enhance the removal rates of the organic pollutants present in the leachate, likely by a putative higher rate of microbial metabolism. Test with six (4.23 gallons) bioreactors assembled with MSW collected from the Salt River Landfill and Southwest Regional Landfill showed that under 5 grams /liter of ZVI and 0.625 grams/liter of ZVMn additions, no significant difference was observed in the pH and temperature data of the leachate generated from these reactors. The conductivity data suggested the steady rise across all reactors over the period of time. The removal efficiency of sCOD was highest (27.112 mg/lit/day) for the reactors added with ZVMn at the end of 150 days for bottom layer, however the removal rate was highest (16.955 mg/lit/day) for ZVI after the end of 150 days of the middle layer. Similar trends in the results was observed in TC analysis. HPLC study indicated the dominance of the concentration of heptanoate and isovalerate were leachate generated from the bottom layer across all reactors. Heptanoate continued to dominate in the ZVMn added leachate even after middle layer injection. IC analysis concluded the chloride was dominant in the leachate generated from all the reactors and there was a steady increase in the chloride content over the period of time. Along with chloride, fluoride, bromide, nitrate, nitrite, phosphate and sulfate were also detected in considerable concentrations. In the summary, the addition of the zero valent metals has proved to be efficient in removal of the organics present in the leachate.
