Taxing Buybacks, Gregg Polsky, Daniel J. Hemel

Scholarly Works

A recent rise in the volume of corporate share repurchases has prompted calls for changes to the rules governing stock buybacks. These calls for reform are animated by concerns that buybacks enrich corporate executives at the expense of productive investment. This emerging antibuyback movement includes prominent politicians as well as academics and Republicans as well as Democrats. The primary focus of buyback critics has been on securities-law changes to deter repurchases, with only passing mention of potential tax-law solutions. This Article critically examines the policy arguments against buybacks and arrives at a mixed verdict. On the one hand, claims that …

Enabling Machine Learning On The Edge Using Sram Conserving Efficient Neural Networks Execution Approach, Bharath Sudharsan, Pankesh Patel, John G. Breslin, Muhammad Intizar Ali

Publications

Edge analytics refers to the application of data analytics and Machine Learning (ML) algorithms on IoT devices. The concept of edge analytics is gaining popularity due to its ability to perform AI-based analytics at the device level, enabling autonomous decision-making, without depending on the cloud. However, the majority of Internet of Things (IoT) devices are embedded systems with a low-cost microcontroller unit (MCU) or a small CPU as its brain, which often are incapable of handling complex ML algorithms.

In this paper, we propose an approach for the ecient execution of already deeply compressed, large neural networks (NNs) on tiny …

Semantics Of The Black-Box: Can Knowledge Graphs Help Make Deep Learning Systems More Interpretable And Explainable?, Manas Gaur, Keyur Faldu, Amit Sheth

Publications

The recent series of innovations in deep learning (DL) have shown enormous potential to impact individuals and society, both positively and negatively. The DL models utilizing massive computing power and enormous datasets have significantly outperformed prior historical benchmarks on increasingly difficult, well-defined research tasks across technology domains such as computer vision, natural language processing, signal processing, and human-computer interactions. However, the Black-Box nature of DL models and their over-reliance on massive amounts of data condensed into labels and dense representations poses challenges for interpretability and explainability of the system. Furthermore, DLs have not yet been proven in their ability to …

On The Road To Translanguaging In A Dual Language Classroom: Teaching Math And Science In Mandarin And English, Xiaodi Zhou

Bilingual and Literacy Studies Faculty Publications

This article examines the evolving instructional practice of one Chinese dual language instructor in the US as she employs a translanguaging-inspired approach in her math and science Mandarin medium classes. Contrary to the school language allocation policy requiring 90% Mandarin in her Chinese classes, she encourages the utilization of English as well as Mandarin in her instruction. This offers comprehensible input to learners, also making possible greater student participation. Findings from observations and interviews reveal how a focus on meaning-making in instruction resulted in the gradual evolution of bilingual language use and effective communication of content by students and the …

Self-Efficacy And Self-Regulation As Predictors Of Academic Motivation Among Undergraduate Students In The United States, Fatimah Aljuaid

Dissertations

Problem

Some undergraduate students demonstrate lack of academic motivation which negatively affects engagement and perseverance in higher education (Busse & Walter, 2017; Rizkallah & Seitz, 2017; Dresel & Grassinger, 2013). Amotivated students are more likely to drop out of school and disengage from learning activities or underachieve (Wang & Pomerantz, 2009). Although the lack of academic motivation is correlated with deficiency in self-regulation and self-efficacy, relatively little studies have been conducted to examine the impact of these factors on academic motivation particularly in the U.S. This study constructed a hypothesized model to investigate the role of self-regulation and self-efficacy in …

The school had not followed the previous 10-year trend of technology implementation in the classroom, in spite of conclusive research on its advantages. This study was conducted to determine to what extent teaching methodology and the use of technology could affect academic performance in the areas of spelling, vocabulary, and reading comprehension. Research on the implementation of software and the use of tablets (iPad Minis) in the classroom has been scarce and contradictory in the …

An Exploratory Study Of Mathematics Anxiety In Caribbean Preservice Teachers, Franka Atwell-Chin Hong

Dissertations

The Problem

Correlational studies suggest that gender, attitudes to mathematics, mathematics performance, the number of college mathematics courses taken, and mathematics teacher efficacy beliefs may be related to mathematics anxiety among preservice teachers (Boyd et al., 2014; Gresham, 2018; Jaggernauth & Jameson-Charles, 2015). Exploratory studies of mathematics anxiety and teacher self-efficacy among elementary teachers exist in Trinidad and Tobago (Jaggernauth 2012; Jaggernauth & Jameson-Charles, 2015). However, the differences in samples, and weakness in methodology, may make it challenging to generalize the results to the preservice teacher population. In addition, no studies have found which variable or combination of variables is …

Results may further inform and refine health professional education infrastructure changes to support faculty in pedagogical change as they prepare students with the …

Human Centeredness: The Foundation For Leadership-As-Practice In Complex Local/Regional Food Networks, Maryann Martinez

Antioch University Dissertations & Theses

Our local and regional food systems are predominately modeled on a failed capitalist market-based economy. In the absence of corporate accountability, and/or support on the federal policy level, local and regional leadership and self-organized networks are critical to the scaling across and evolution of a moral and equitable food system. Networked food systems leaders are developing the capacity to solve wicked problems, and spark change. Understanding the values and practices of local food systems leadership that initiate, influence, and support activities is essential to understanding how to foster conditions for local and regional food network growth. My dissertation research is …

Decolonizing Food Systems Research – The Case Of Household Agricultural Food Access In Bikotiba, Togo, Katryna Maria Kibler

Antioch University Dissertations & Theses

Indigenous West African farmers are among the most climate change threatened globally. Food insecurity is prevalent in West Africa because ecological, social, political, and economic instabilities, and globalization worsen climate pressures. In this study, I collaborated with the community of Bikotiba (bih-CO-ti-buh), Togo, to understand their household agricultural food access, one aspect of resilience to food insecurity. I adopted a feminist approach of reflexivity, radical vulnerability, and radical empathy, combined with decolonizing principles, to argue that there could be an ethical way for well-trained Western researchers to engage Indigenous communities, if negotiated carefully. Together, Indigenous Research Assistants and I developed …

Experience Of Gender Role Expectations And Negotiation In Second Generation Desi Couples, Deepa Patel

Antioch University Dissertations & Theses

Due to the lack of research on the Desi community, this qualitative study was the first of its kind to investigate the process of gender role expectation and negotiation style among second generation Desi couples. Previous research provided awareness of unequal treatment amongst the male and female genders within the patriarchal structure of the Desi community. However, this study provided a unique understanding on Desi couples’ perspective on gender dynamics. Six couples, ages 25- 35, who were married for at least 3 years and identified as second generation Desi were interviewed in order to gain a deeper understanding of gender …

Meta-Analysis Of Primary Producer Amino Acid Δ15N Values And Their Influence On Trophic Position Estimation, Matthew D. Ramirez, Alexi C. Besser, Seth D. Newsome, Kelton Mcmahon

Graduate School of Oceanography Faculty Publications

1. Compound-specific stable isotope analysis of individual amino acids (CSIA-AA) has emerged as a transformative approach to estimate consumer trophic positions (TP_CSIA) that are internally indexed to primary producer nitrogen isotope baselines. Central to accurate TP_CSIA estimation is an understanding of beta (β) values—the differences between trophic and source AA δ¹⁵N values in the primary producers at the base of a consumers’ food web. Growing evidence suggests higher taxonomic and tissue-specific β value variability than typically appreciated.
2. This meta-analysis fulfills a pressing need to comprehensively evaluate relevant sources of β value variability and its contribution to …

Higher Education's Immunity To Change: Understanding How Leaders Make Meaning Of Their Student Success Landscape, Brittany Motley

Antioch University Dissertations & Theses

Closing equity gaps in the higher education sector is a long-standing issue. This issue has become exacerbated with the impact of COVID-19 and racial injustices happening across America. Now more than ever it has become imperative to use participatory action research to understand how leaders make meaning of their student success landscape and use that meaning to influence their strategic action for equity. I engaged two student success stakeholders from one university as co-researchers to help identify a problem in practice as it relates to equity gaps in student success. We used a modified approach to immunity to change (ITC) …

Bound States And Energy Eigenvalues Of A Radial Screened Coulomb Potential, Eric Stachura, N. Hancock

Faculty Articles

We analyze bound states and other properties of solutions of a radial Schrödinger equation with a new screened Coulomb potential. In particular, we employ hypervirial relations to obtain eigen-energies for a Hydrogen atom with this potential. Additionally, we appeal to a sharp estimate for a modified Bessel function to estimate the ground state energy of such a system. Finally, when the angular quantum number ℓ ≠ 0, we obtain evidence for a critical screening parameter, above which bound states cease to exist.

Faculty Articles

The increasingly popular microbiopsy is an appealing alternative to the more invasive Bergström biopsy given the challenges associated with harvesting skeletal muscle in older populations. Parameters of muscle fiber morphology and composition derived from the microbiopsy have not been compared between young and older adults. The purpose of this study was to examine muscle fiber morphology and composition in young (YM) and older (OM) males using the microbiopsy sampling technique. A secondary aim was to determine if specific strength is associated with serum levels of C-terminal agrin fragment [CAF; an indicator of neuromuscular junction (NMJ) degradation]. Thirty healthy, YM ( …

Effects Of Advance Refunding Municipal Bonds After The U.S. Tax Cuts And Jobs Act, Sarah Curry

Doctor of Business Administration Dissertations

The process when U.S. municipalities retire callable bonds early and refinance them with bonds of a lower coupon rate is called advance refunding. The advance refunding of debt is a widespread practice in municipal finance; however, the Tax Cuts and Jobs Act of 2017 removed the option to keep this debt tax-exempt and now requires municipalities to convert from tax-exempt to taxable. The purpose of this research was to evaluate the impact eliminating advance refunding of municipal debt into tax-exempt status has on the municipality’s advance refunding decision making process, specifically at the state level. Municipal governments are still …

International Law As Behavior: An Agenda, Harlan G. Cohen, Timothy Meyer

Scholarly Works

Over the past few decades, scholars in a variety of fields – economics, psychology, sociology, anthropology, and international relations, among others – have made enormous strides studying the behavioral roots of international law by exploring individual motivations, describing organizational cultures, and mapping communities of practice. Taken together, the work of these scholars presents a complex, nuanced understanding of how international law works. However, these projects are rarely considered together: often separated by academic enclosures and focused on different subfields within international law, communication among scholars using different methodologies is restricted. The goal of this book is to break down some …

On Quasilinear Elliptic Problems With Finite Or Infinite Potential Wells, Shibo Liu

Mathematics and System Engineering Faculty Publications

We consider quasilinear elliptic problems of the form - div (φ (| ∇ u |) ∇ u) + V (x) φ (| u |) u = f (u), u ∈ W 1, φ (R N), where φ and f satisfy suitable conditions. The positive potential V ∈ C (R N) exhibits a finite or infinite potential well in the sense that V (x) V\left(x) tends to its supremum V ∞ ≤ + ∞ as | x | → ∞. Nontrivial solutions are obtained by variational methods. When V ∞ = + ∞, a compact embedding from a suitable subspace of …

Efficient Algorithms For Identifying Loop Formation And Computing Θ Value For Solving Minimum Cost Flow Network Problems, Timothy Michael Chávez, Duc Thai Nguyen

Computational Modeling & Simulation Engineering Faculty Publications

While the minimum cost flow (MCF) problems have been well documented in many publications, due to its broad applications, little or no effort have been devoted to explaining the algorithms for identifying loop formation and computing the value needed to solve MCF network problems. This paper proposes efficient algorithms, and MATLAB computer implementation, for solving MCF problems. Several academic and real-life network problems have been solved to validate the proposed algorithms; the numerical results obtained by the developed MCF code have been compared and matched with the built-in MATLAB function Linprog() (Simplex algorithm) for further validation.

Identification Of New Pathways For Co Oxidation On Rh(111) & Spatial And Structural Control Of O-Induced Reconstruction Of Ag(111), Marie Turano

Dissertations

Understanding the fundamentals of oxygen surface structures under a variety of conditions is pivotal to determining reactivity of heterogeneous catalysis. Exposure of catalytically active metal surfaces to high oxygen coverages results in a myriad of surface structures. A further complication is the formation of subsurface oxygen (Osub) or oxygen present in the near subsurface region of the metal. It is known to form in transition metals yet the absorption of oxygen and resultant formation of Osub is not equivalent across all catalytically relevant metals. As a result, it is difficult to predict the stability and efficacy of the formation of …
