A Library Of Low Molecular Weight Fluorescent Probes For The Detection Of Cu(Ii) And Fe(Iii) Ions, Ashley Johnson

Dissertations

This dissertation reports the synthesis and photophysical properties of a family of rhodamine dyes (compounds 3.9-3.13 and 4.6). The rhodamine dyes are prepared in two steps, and fully characterized by ESI-MS (Low and High resolution), X-Ray crystallography, NMR spectroscopy, and FT-IR spectroscopy. The coordination environment of the low molecular weight fluorescent probes (LMFPs) was systematically changed to investigate the thermodynamic behavior between the LMFPs and an array of metal ions (Cu²⁺, Fe²⁺, and Hg²⁺ ions) in protic and aprotic solvent systems. Upon coordinating to metal ions, the π-conjugation of the LMFPs changed, resulting in …

Diversity And Inclusion: Examining The Lived Experiences Of Lgbtq Students At Historically Black Colleges And Universities (Hbcus) In The Bible Belt, Steven Jones

Dissertations

Throughout the twentieth century, the Gay Rights Movement has gained momentum as LGBTQ (Lesbian, Gay, Bisexual, Transgender, Queer) individuals have fought for civil equality and social acceptance. However, Historically Black Colleges and Universities (HBCUs) have been slow to adapt, implement, and effect change that improves the quality of education for LGBTQ students. Strong religious beliefs derived from the church; especially in the South, may be the connection to understanding why homosexuality isn’t vastly accepted or celebrated in the Black Community and at HBCUs; particularly, in the Bible Belt.

Thus, this phenomenological qualitative study, guided by the theory of care framework, …

Editing The Double Bass Concerto Of Antonio Scontrino, Roberto Pineda

Dissertations

Antonio Scontrino (1850-1922) was an important Italian Romantic composer, virtuoso double bassist, and respected pedagogue who is relatively unknown outside of the Italian musical community. His compositional output is prolific and includes string quartets, operas, symphonies, concerti, solo pieces, songs, and religious works. Indeed, Scontrino was a compelling composer who deserves more attention from the international musical community. In addition to his compositional expertise, he was an artful double bass performer whose works for the instrument, while distinctly idiomatic, are compositions of high quality.

This dissertation provides a description of the composer’s life and the events that transpired around Scontrino …

A qualitative research methodology was employed to investigated the insight of CTE teachers’ attitudes toward the professional developments that they had attended. This study also investigated whether training was appropriate to teachers’ learning needs in high school districts in MS. The population for this study included seven high school career and technical teachers in five …

Practical Adhesion Measurements In Organic Coatings; Advancing Understanding And Mechanical Methods Development, Diana Gottschalk

Dissertations

“Adhesion” can be considered either a mechanical or chemical phenomenon. The mechanical interpretation describes the difficulty of separating surfaces and is useful for quantifying performance within applications that depend on bulk and interfacial properties. Chemical adhesion describes interfacial resistance to chemical attack and does not depend on bulk properties. Predicting chemical failure through mechanical measurement is confounded by the influence of bulk properties. However, the prospect is attractive because of the robust tolerance for sample geometries, allowing experiments to resemble an end-use system. The present work's primary goal was to elevate mechanical methods to provide a detailed interfacial characterization of …

Eelgrass (Zostera Marina) Populatin Delcine In Morro Bay, Ca: A Meta-Analysis Of Herbicide Application In San Luis Obispo County And Morro Bay Watershed, Tyler Sinnott

Master of Science in Environmental Sciences and Management Projects

The endemic eelgrass (Zostera marina) community of Morro Bay Estuary, located on the central coast of California, has experienced an estimated decline of 95% in occupied area (reduction of 344 acres to 20 acres) from 2008 to 2017 for reasons that are not yet definitively clear. One possible driver of degradation, that has yet to be investigated is the role of herbicides from agricultural fields in the watershed that feeds into the estuary. Thus, the primary research goal of this project was to better understand temporal and spatial trends of herbicide use within the context of San Luis Obispo (SLO) …

Antenna Radiation Element Designs For 5g Applications, Zhijun Gui

Electrical Engineering Undergraduate Honors Theses

This thesis introduced the advantage of the fifth-generation network and gave examples to the three major classes of applications categorized by International Telecommunication Union-Radiocommunication Sector. In this work, a patch antenna and a board-band bow-tie antenna with microelectromechanical switch design were modified to meet 5G communication purposes. The revised patch antenna produced a minimum S11 of -57.92dB, a resonant frequency at the 28GHz, and bandwidth of 4.55GHz. The modified design meets the requirements for wireless communication purposes. During the duplication process of the board-band bow-tie antenna design, multiple discrepancies were found, and the proposed results were not able to achieve. …

Puerto Rico’S Electric Power System: An Analysis Of Contemporary Failures And The Opportunity To Rebuild A More Resilient Grid, Including The Development Of A Utility-Scale Solar Farm On The Island Municipality Of Culebra, Federico Sotomayor

Sustainability and Social Justice

Puerto Rico’s grid was decimated in 2017 after experiencing back-to-back hurricanes – Maria and Irma. Although the hurricanes caused tremendous damage and hardship to the island, it also created the right circumstances for the local energy landscape to transition toward a more resilient and sustainable model. Through an analysis of recent challenges by the local electric utility PREPA, and subsequent fallout from the hurricanes, we see that they now hold a unique opportunity to redeem themselves by taking advantage of catalyzed resources to rebuild a better system. One region that could greatly benefit from an improved and reimagined grid are …

Students Who Took The Class Help Studenrs Who Are Taking It: What Is The Best Arrangement?, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

The more help students get, the better. It is therefore reasonable to ask students who took the class to help students who are currently taking this class. This arrangement also help the helpers: it is known that the best way to learn the material is to teach it. An important question is: how to pair the students to get the maximal effect? In this paper, we show that, under reasonable conditions, the best effect is when we match the best performing "older" student with the worst performing "younger" one, the second best with the second worst, etc.

Just-In-Time Teaching Adds Motivation But Is Less Efficient, Vladik Kreinovich, Olga Kosheleva, Christian Servin

Departmental Technical Reports (CS)

For each major, in addition to directly major-related topics, students also need to learn auxiliary topics –- e.g., math topics –- which are needed to understand more direct major-related ones. To learn these auxiliary topics, students are required to take some prerequisite math class. The problem is that when the students take these classes, they do not fully understand how these classes are related to their major. As a result, they often lack motivations, do not study well, and this hinders their performance in the follow-up major-related classes. One way to enhance the students' motivation is to use just-in-time teaching, …

So How Were The Tents Of Israel Placed? A Bible-Inspired Geometric Problem, Julio Urenda, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In one of the Biblical stories, prophet Balaam blesses the tents of Israel for being good. But what can be so good about the tents? A traditional Rabbinical interpretation is that the placement of the tents provided full privacy: from each entrance, one could not see what is happening at any other entrance. This motivates a natural geometric question: how exactly were these tents placed? In this paper, we provide an answer to this question.

Building Postsecondary Pathways For Latinx Students In Computing: Lessons From Hispanic-Serving Institutions, Anne-Marie Núñez, David S. Knight, Sanga Kim

Departmental Technical Reports (CS)

While the COVID-19 pandemic has transformed the use of technology in education and the workforce, a shortage of computer scientists continues, and computing remains one of the least diverse STEM disciplines. Efforts to diversify the computing industry often focus on the most selective postsecondary institutions, which are predominantly White. We highlight the role of Hispanic-Serving Institutions (HSI) in gradating large numbers of STEM graduates of color, particularly Latinx students. HSIs are uniquely positioned to leverage asset-based approaches that value students’ cultural background. We describe the practices educators use in the Computing Alliance for Hispanic-Serving Institutions, a network of 40 HSIs …

Why Physical Processes Are Smooth Or Almost Smooth: A Possible Physical Explanation Based On Intuitive Ideas Behind Energy Conservation, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

While there are some non-smooth (and even discontinuous) processes in nature, most processes are smooth or almost smooth. This smoothness help estimate physical quantities, but a natural question is: why are physical processes smooth or almost smooth? Are there any fundamental reasons for this ubiquitous smoothness? In this paper, we provide a possible physical explanation for emirical smoothness: namely, we show that smoothness naturally follows from intuitive ideas behind energy conservation.

Need For Shift-Invariant Fractional Differentiation Explains The Appearance Of Complex Numbers In Physics, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Complex numbers are ubiquitous in physics, they lead to a natural description of different physical processes and to efficient algorithms for solving the corresponding problems. But why this seemingly counterintuitive mathematical construction is so natural here? In this paper, we provide a possible explanation of this phenomenon: namely, we show that complex numbers appear if take into account that some physical system are described by derivatives of fractional order and that a physically meaningful analysis of such derivatives naturally leads to complex numbers.

The Circadian Clock—A Molecular Tool For Survival In Cyanobacteria, Pyonghwa Kim, Manpreet Kaur, Hye-In Jang, Yongick Kim

Chemistry Faculty Research

Cyanobacteria are photosynthetic organisms that are known to be responsible for oxygenating Earth’s early atmosphere. Having evolved to ensure optimal survival in the periodic light/dark cycle on this planet, their genetic codes are packed with various tools, including a sophisticated biological timekeeping system. Among the cyanobacteria is Synechococcus elongatus PCC 7942, the simplest clock-harboring organism with a powerful genetic tool that enabled the identification of its intricate timekeeping mechanism. The three central oscillator proteins—KaiA, KaiB, and KaiC—drive the 24 h cyclic gene expression rhythm of cyanobacteria, and the “ticking” of the oscillator can be reconstituted inside a test tube just …

Hategan: Adversarial Generative-Based Data Augmentation For Hate Speech Detection, Rui Cao, Roy Ka-Wei Lee

SCIS Student Publications

Academia and industry have developed machine learning and natural language processing models to detect online hate speech automatically. However, most of these existing methods adopt a supervised approach that heavily depends on labeled datasets for training. This results in the methods’ poor detection performance of the hate speech class as the training datasets are highly imbalanced. In this paper, we propose HateGAN, a deep generative reinforcement learning model, which addresses the challenge of imbalance class by augmenting the dataset with hateful tweets. We conduct extensive experiments to augment two commonly-used hate speech detection datasets with the HateGAN generated tweets. Our …

National Park Interpretation And Place-Based Education: An Integrative Literature Review, Steph N. Dean

Publications

Background: Both national park (NP) interpretation and place-based education (PBE) approach learning by applying the unique attributes of a place to facilitate meaning-making experiences within learners. Despite the similarities between these two place-centered pedagogies, there is a limited amount of collaboration between NP interpretative services and school systems engaged with PBE. Purpose: Within this integrative review, my purpose is to fully consider both NP interpretation and PBE to present a comprehensive understanding of the two types of pedagogies. Methodology/Approach: Following an integrative review methodology, I use three different databases to access relevant empirical and theoretical articles. I evaluate and analyze …

Approximating Special Social Influence Maximization Problems, Jie Wu, Ning Wang

College of Science & Mathematics Departmental Research

Social Influence Maximization Problems (SIMPs) deal with selecting k seeds in a given Online Social Network (OSN) to maximize the number of eventually-influenced users. This is done by using these seeds based on a given set of influence probabilities among neighbors in the OSN. Although the SIMP has been proved to be NP-hard, it has both submodular (with a natural diminishing-return) and monotone (with an increasing influenced users through propagation) that make the problem suitable for approximation solutions. However, several special SIMPs cannot be modeled as submodular or monotone functions. In this paper, we look at several conditions under which …

Using The Chi-Square Test To Analyze Voter Behavior, Bailey Fadden

Mathematics Senior Showcase 2020

Economics And Game Theory, Jeremiah Patrick Prenn

Mathematics Senior Showcase 2020

Game theory is one of the major fields of mathematics. Game theory is the study of how games, their players, and players’ strategies are defined, and how the games might play out. The outcomes of games are ultimately based on decisions, much like in the science of economics. Economics analyzes how scarce resources are to be allocated to suit unlimited needs. Every decision has an economic cost, and every decision has a utility value (utility being a quantitative measure of usefulness). Economics and game theory go hand in hand: Both analyze the effects of decisions and the rules imposed on …

Gender Pay Discrimination & The Equal Pay Act: Legal Research & Methods, Emily Sullivan

Law Student Works

More than 50 years since the Equal Pay Act (1963) was passed, the subject of wage inequality between the sexes remains a critical topic for women, members of Congress, advocacy groups, business and legal communities. Within the last decade, the legal community has seen a wave of litigation alleging discrimination across a wide variety of industries, including within the legal field itself. Wage discrimination has negative consequences for women, communities, and employers—discrimination in the workplace is inefficient and resulting litigation is costly.

In this Pathfinder guide, you will find a brief background on the Equal Pay Act as it pertains …
