Back To The Drawing Board: Revisiting The Supreme Court's Stance On Partisan Gerrymandering, Robert Colton

Fordham Law Review

In the United States, state legislatures have drawn voting districts to achieve desired election results for hundreds of years. Dating back to the James Madison presidency, various legislatures and iterations of the U.S. Supreme Court have wrestled with the legal and constitutional issues that stem from the practice known as “gerrymandering.” While courts and legislatures have, at times, been successful in eliminating some of the more sinister uses of the tactic, such as racially motivated district-line drawing, gerrymandering inspired by partisan motives remains. Continual improvements in technology coupled with an increasingly divided political culture mean that partisan gerrymandering is at …

Physics & Astronomy Faculty Publications

The Advanced LIGO and Advanced Virgo observatories recently discovered gravitational waves from a binary neutron star inspiral. A short gamma-ray burst (GRB) that followed the merger of this binary was also recorded by the Fermi Gamma-ray Burst Monitor (Fermi-GBM), and the Anti-Coincidence Shield for the Spectrometer for the International Gamma-Ray Astrophysics Laboratory (INTEGRAL), indicating particle acceleration by the source. The precise location of the event was determined by optical detections of emission following the merger. We searched for high-energy neutrinos from the merger in the GeV-EeV energy range using the Antares, IceCube, and Pierre Auger Observatories. No neutrinos directionally coincident …

Ph Effect On The Formation Of Thm And Haa Disinfection Byproducts And Potential Control Strategies For Food Processing, Yen-Con Hung, Brian W. Waters, Veerachandra K. Yemmireddy, Ching-Hua Huang

School of Earth, Environmental, & Marine Sciences Faculty Publications

Chlorine-based sanitizers have seen wide spread use in food sanitation. The reaction of chlorine species with organic matter is a concern for two reasons. Available chlorine can be “used up” by organic compounds resulting in a lower amount of chlorine available for disinfection. Another concern is that some forms of chlorine can react with some organic compounds to form toxic halogenated disinfection byproducts (DBPs). Many studies have been conducted to evaluate the role of hypochlorous acid (HOCl) and hypochlorite ion (OCl−) in the production of DBPs with a particular interest in the production of trihalomethanes (THMs) and haloacetic acids (HAAs). …

The molecules were considered in their neutral and anionic forms to account for the change in pH depending on the medium of the drug-receptor interactions. Conclusion: The new developed approach, …

Mechanistic Studies Of The Iron And Molybdenum Nitrogenases, Derek Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As a basic building block in many biological molecules the element nitrogen (N) is essential for life. Dinitrogen (N2) is abundant in Earth’s atmosphere, but this form is biologically unavailable. To be biologically available N2 must undergo an energy demanding reduction reaction to the fixed form, ammonia (NH3). The industrial Haber-Bosch process, which accounts for approximately 50% of the worlds fixed nitrogen, uses energy from fossil fuels to achieve high pressures and temperatures to facilitate the reaction. The energy used by Haber-Bosch accounts for approximately 2% of the world’s annual supply. The remainder of fixed nitrogen is produced biologically by …

Ethics And Bias In Machine Learning: A Technical Study Of What Makes Us “Good”, Ashley Nicole Shadowen

Student Theses

The topic of machine ethics is growing in recognition and energy, but bias in machine learning algorithms outpaces it to date. Bias is a complicated term with good and bad connotations in the field of algorithmic prediction making. Especially in circumstances with legal and ethical consequences, we must study the results of these machines to ensure fairness. This paper attempts to address ethics at the algorithmic level of autonomous machines. There is no one solution to solving machine bias, it depends on the context of the given system and the most reasonable way to avoid biased decisions while maintaining the …

Study Of Self-Similarity In Brain Data, Jennifer Holst

Student Theses

In the area of computer science, past research has found that the concept of self-similarity is present in local and Internet-based network traffic. This study considers the possibility that data traveling through the neuronal network in the human brain is also self-similar. By analyzing publicly available raw EEG data and estimating its Hurst parameter, we find indications that brain data traffic may in fact be self-similar.

Analysis Of Safety Impacts Of Access Management Alternatives Using The Surrogate Safety Assessment Model, Kyung Min Kim

Theses and Dissertations

In a traditional safety impact analysis, it is necessary to have crash data on existing roadway conditions in the field and a few years must pass before accumulating reliable crash data. This is a time-consuming approach and there remains uncertainty in the crash data due to the random nature of crash occurrences. The Surrogate Safety Assessment Model (SSAM) was developed for resolving these issues. With SSAM, a conflict analysis is performed in a simulated environment. A planned improvement alternative under study is modeled and no physical installation of the alternative is needed. Hence, the method using a simulation software along …

An Investigation Of Elementary Teachers<'> Self-Efficacy For And Beliefs About The Importance Of Engineering Education, Khristen Lee Massic

Theses and Dissertations

In order for the United States to regain its global standing in science and engineering, educational and governmental organizations have started to re-emphasize science, technology, engineering, and math content in k-12 classrooms.While some preliminary research has been conducted on student and teacher perceptions related to engineering, there has been little research conducted related to teachers beliefs about the importance of engineering content in their classrooms and relatively few studies have investigated elementary teachers teaching engineering self-efficacy. Current studies have investigated the impact of professional development on teachers teaching engineering self-efficacy but these studies were conducted with limited sample sizes, for …

Foxes At The Henhouse: Occupational Licensing Boards Up Close, Rebecca Haw Allensworth

Vanderbilt Law School Faculty Publications

The dark side of occupational licensing-its tendency to raise prices to consumers with dubious effects on service quality, its enormous payout to licensees, and its ability to shut many willing workers out of the workforce-has begun to receive significant attention. But little has been said about the legal institutions that create and administer this web of professional entry and practice rules. State-level licensing boards regulate nearly one-third of American workers, yet, until now, there has been no systematic attempt to understand who serves on these boards and how they operate. This Article undertakes an ambitious and comprehensive study of all …

The Production Function Of The Regulatory State, J.B. Ruhl, Jonathan R. Nash, James Salzman

Vanderbilt Law School Faculty Publications

How much will our budget be cut be this year? This question has loomed ominously over regulatory agencies for over three decades. After the 2016 presidential election, it now stands front and center in federal policy, with the Trump administration pledging over $50 billion in cuts. Yet very little is known about the fundamental relationship between regulatory agencies budgets and the social welfare outcomes they are charged to produce. Indeed, the question is scarcely studied in scholarship from law, economics, or political science. This article lays the groundwork for a new field of theoretical and empirical research, using what we …

Thinking Before You Act: A Constructive Logic Approach To Crafting Performance-For- Development Narrative, Angela Duggins

Electronic Theses and Dissertations

The intent of this thesis was to test the feasibility of constructing performance-for-development narrative using a constructive logic approach. I created an equation which expressed the sum of non-human-elements as the sum of a narrative with each element serving as a variable. I used a review of persuasion literature to provide insight into the selection and manipulation of each variable. I provided my family as a hypothetical example and used my knowledge of their preferences and communication styles in conjunction with the literature and the equation to craft a narrative which might increase pro-school attitudes in other families like my …

Localization Of Generalized Frames In Hilbert Spaces: Asymptotic Behavior Of Concentration And Toeplitz Operators, Sampling And Interpolation, And Density Results, Aarón Ernesto Ramírez Flores

All Dissertations

Suppose H is a separable and complex Hilbert space with a generalized frame (also known as continuous frame) indexed over a metric measure space X. We study the main properties of generalized frames and the operators defined by them, such as concentration operators and Toeplitz operators. Imposing certain localization conditions to the generalized frame, we describe the asymptotic behavior of concentration and Toeplitz operators, and derive important results about the distribution of their eigenvalues. Furthermore, working with multiple generalized frames in H intertwined by a localization conditions, we obtain very general density results. Many examples and applications are shown, among …

Flow Assessment Using Optical Coherence Microscopy Based Particle Image Velocimetry, Siyu Ma

All Dissertations

Congenital heart diseases (CHDs) are the most common forms of congenital malformation in newborns. Among all types of CHDs, a large portion is contributed by malformation of endocardial cushion malformation during early heart development. Although the etiology of endocardial cushion malformation is unclear, it is a result of interactions between genetic and environmental factors has been confirmed. There is hypothesis indicating that malformation of endocardial cushion is caused by altered shear stress conditions where in cushion forming area the shear stress is supposed to be high compare with other area in congenital heart. However it is difficult to justify due …

Using App Inventor To Explore Low-Achieving Students' Understanding Of Fractions, Lorraine Ann Jacques

All Dissertations

A student's understanding of fraction magnitude impacts his/her understanding of algebra (e.g., Booth & Newton, 2012; Siegler et al., 2012), which then influences his/her likelihood of graduating high school (Orihuela, 2006) or succeeding in higher education (Adelman & United States., 2006; Trusty & Niles, 2004). Literature suggests that students gain this understanding when they create and work with various representations of fractions (e.g., Ainsworth, Bibby, & Wood, 2002; Panaoura et al., 2009; Siegler, Fazio, Bailey, & Zhou, 2013), which can occur when students engage in constructivist activities such as developing games (Kafai, 1996, Apr). This study examines an intervention where …

Microwave Photonics For Distributed Sensing, Liwei Hua

All Dissertations

In the past few years, microwave-photonics technologies have been investigated for optical fiber sensing. By introducing microwave modulation into the optical system, the optical detection is synchronized with the microwave modulation frequency. As a result, the system has a high SNR and thus an improved detection limit. In addition, the phase of the microwave-modulated light can be obtained and Fourier transformed to find the time-of-arrival information for distributed sensing. Recently, an incoherent optical-carrier-based microwave interferometry (OCMI) technique has been demonstrated for fully distributed sensing with high spatial resolution and large measurement range. Since the modal interference has little influence on …
