Education Inequity: A Comparative Analysis Of Johannesburg And Chicago City Schools, Melissa Marie Johnson

Honors Program Theses

Variances in the quality of education between schools in the same metropolitan areas have been noted around the world, and researchers have speculated on several causes. In order to study the specific impacts of funding gaps, lower numbers and qualifications of teachers, and lack of resources for students learning English, the cities of Johannesburg and Chicago were compared and contrasted. Both cities contained areas with very high quality schools and isolated neighborhoods where schools generally had fewer resources and lower test scores. This research shows that the problems in both cities mirror one another to an extent. Schools systems in …

Predicting Genome Terminus Sequences Of Bacillus Cereus-Group Bacteriophage Using Next Generation Sequencing Data, Cheng-Han Chung, Michael H. Walter, Luobin Yang, Shu-Chuan (Grace) Chen, Vern Winston, Michael A. Thomas

Faculty Work

Background: Most tailed bacteriophages (phages) feature linear dsDNA genomes. Characterizing novel phages requires an understanding of complete genome sequences, including the definition of genome physical ends.

Result: We sequenced 48 Bacillus cereus phage isolates and analyzed Next-generation sequencing (NGS) data to resolve the genome configuration of these novel phages. Most assembled contigs featured reads that mapped to both contig ends and formed circularized contigs. Independent assemblies of 31 nearly identical I48-like Bacillus phage isolates allowed us to observe that the assembly programs tended to produce random cleavage on circularized contigs. However, currently available assemblers were not capable of …

Formation Of Titan Aerosol From Co And Ch4, Tate Christensen

Honors Program Theses

In 1952 Stanley Miller and Harold Urey conducted an experiment that would simulate the conditions of early earth (Miller, 1953). The purpose was to observe the chemical origins of life, and the conclusion supported an earlier theory that such conditions favor the synthesis of more complex organic compounds from simpler inorganic molecules. The research conducted in Dr. Sebree’s lab is an extension of these early findings. It is believed that early Earth was composed mostly of nitrogen, carbon monoxide, carbon dioxide and methane as opposed to our atmosphere of nitrogen and oxygen today.

Saturn’s largest moon, Titan, has qualities relatively …

Magnetic Behavior Of Bulk And Nanostructured Mnxtas2, Lucas Paul Beving

Honors Program Theses

At its base, material science research aims to categorize specific materials by their various attributes, such as structure, integrity, electronic properties, magnetic properties, and others. By categorizing materials in this way, it becomes easier to generalize the application of a specific material to those within a broader category. The interest in materials that exhibit useful characteristics at small scales derives directly from the technology industry’s need for smaller and smaller devices. Two-dimensional materials are of great interest for this reason.

Two-dimensional materials are comprised of many single layers, or planes, stacked together to create a crystal. Each layer may be …

Secondary Mathematics Educators And Coaches' Role In Providing Motivation, Reggie Schulte

Honors Program Theses

The compatibility between learning goals for students and mastery-oriented athletes makes sense based on my experience in both fields. I have often heard from coaches that it is important to “embrace the process” or “trust the process.” This same idea can be applied to a mathematics secondary classroom by praising effort and embracing the struggle that comes along with having a conceptual understanding of mathematics. As a future educator and coach, it is exciting, and to be honest somewhat scary, to know that I can a great effect on what my students believe they are able to achieve. After conducting …

Realizing Edgar: Eliminating Information Asymmetries Through Artificial Intelligence Analysis Of Sec Filings, Ryan H. Giarusso

Honors Program Theses

The U.S. Securities and Exchange Commission (SEC) maintains a publicly-accessible database of all required filings of all publicly traded companies. Known as EDGAR (Electronic Data Gathering, Analysis, and Retrieval), this database contains documents ranging from annual reports of major companies to personal disclosures of senior managers. However, the common user and particularly the retail investor are overwhelmed by the deluge of information, not empowered. EDGAR as it currently functions entrenches the information asymmetry between these retail investors and the large financial institutions with which they often trade. With substantial research staffs and budgets coupled to an industry standard of “playing …

An Experimental Study Of Non-Metallic Inclusions Precipitation And Its Effect On Impact Toughness Variations In Low Alloy Steel Subjected To Complex Deoxidation, Pavel Bizyukov

Dissertations and Theses @ UNI

A low level of non-metallic inclusions in steel is the key requirement in the concept of clean steel. Although the concept has received its name quite recently, it has been implemented at the large-scale steel mills for more than 40 years. Production of clean steel became possible due active development and adoption of the post-melting treatment of molten metal in the teeming ladle. Ladle metallurgy, an umbrella term for various methods of treatment, includes operations that cannot be performed during primary metallurgical processes such as melting in an electric arc, basic oxygen, or air induction furnace. Initially, the most common …

Properties Of Left-Separated Spaces And Their Unions, Eric Scheidecker

Dissertations and Theses @ UNI

Left-separated spaces are topological spaces which can be well ordered such that every initial segment is closed. In this paper, we examine what topological properties imply left-separation, and under what circumstances left-separation is preserved by unions. We also introduce several known theorems regarding elementary submodels as they are one of the primary tools that we use. We prove that for a topological space X;

1. If X has a point-countable base, then X is left-separated if and only if X has closed intersection with any elementary submodel M such that X ∈ M.

2. If every elementary submodel …

A Qualitative Comparison Of General Chemistry And Advanced Placement Chemistry Students' Misconceptions Regarding Solution Chemistry, Megan J. Vandersee

Dissertations and Theses @ UNI

This study focused on identifying misconceptions which high school AP and collegiate general chemistry students hold with regards to solution chemistry topics and comparing the misconceptions held by each student group. Previous research has found that misconceptions can greatly impact students’ understanding of material and have a negative impact on student learning. However, not all solution chemistry topics had been explored in previous research. In addition, it has been suggested that collegiate students have reached a higher level of cognitive development as they are older and more advanced in their studies. If this is the case, one could assume that …
