Racism Detection In Tweets, Ndjeuha Gihane

All Graduate Projects

Since the advent of social networks in 1997, businesses and people’s lives have changed in a good way. From promoting companies to reaching out to friends and family, social networking has become a major element in our lives. X is a very popular platform that is used by many people, including celebrities and politicians, to communicate with their audience. Like other platforms, X is not spared by the racism contained in the tweets. We should be able to catch those racist comments on any social media and block the accounts of those responsible for them. To do so, we have …

Computing The Roots Of Twisting Sheaves Over The Projective Line Arising From Monodromy Representations, Diego Yepez

Wayne State University Dissertations

Given a monodromy representation of the projective line minus a finite number of points, one can extend the resulting vector bundle with connection map canonically to a vector bundle with logarithmic connection map over all of the projective line. Now, since vector bundles split as twisting sheaves over the projective line, the focus of this work regards knowing the exact decomposition.

An Ex-Vivo Investigation Of The Effect Of Skin Conditioning With Formulation Vehicles On The Dermal Disposition Of Diphenhydramine Perfused Directly Into The Dermis, Nasim Rezvani Haghighi Shirazi

Selected Full-Text Dissertations 2020-

It is well known that the composition/excipients of a topical dermatological drug product (TDDP) affect the permeation of an active pharmaceutical ingredient (API) through the skin. While it is generally accepted that the vehicle mostly modulates the release of the API from the product, little is known whether the vehicle might also influence the kinetics of the API within the skin itself. In one attempt to answer this question, we developed an ex-vivo model using pig ear and a retrodialysis/microdialysis technique to deliver the API directly into dermis and measure the API dermal pharmacokinetics (dPK). We compared the dPK of …

From Teacher Attrition To Teacher Retention: The Role Of School Principals, Karen Balmer

All Electronic Theses and Dissertations

This quantitative study explored the role of school principals as an intervention to the teacher shortage crisis in the United States. The shortage of teachers is not a new topic in public policy and research; however, the strategies set forth in prior literature have not yielded substantive change to this stubborn problem. Using data from the 2020–2021 National Teacher and Principal Survey, this study analyzed the relationship between the perceptions of early career teachers (within the first 5 years of teaching) about behaviors of their school principals and these teachers’ intentions to remain in the teaching profession. Specifically, this study …

Teachers’ Attrition: Relationship Between Principals’ Communication And Teachers’ Job Satisfaction, Jason Robert Menth

All Electronic Theses and Dissertations

This study investigated the relationship between teachers’ job satisfaction and teachers’ satisfaction with their salary, the number of years teaching, and the principals’ communication about the kind of school they want. Teacher attrition in the K–12 public school system is a well-documented problem citing many motives and causes. The recruitment of educators and retention of teachers in public schools has vastly decreased, creating a significant teacher shortage problem. Resulting complications are fewer applicants for open positions, applicants without the desired licensure, added stress on current teachers to fulfill duties, decreasing student academic progress, and dissatisfied teachers. This quantitative study used …

Organizational Factors And Teachers' Burnout And Attrition, Tony Alberts

All Electronic Theses and Dissertations

This study investigates factors influencing teacher retention and attrition, emphasizing the roles of demographic characteristics, salary, salary satisfaction, burnout, and working conditions. Utilizing data from the 2020–2021 National Teacher and Principal Survey (NTPS), which included approximately 76,000 teachers across 9,000 public schools, the research applies logistic regression to identify significant relationships between these variables. The findings reveal that salary satisfaction, irrespective of actual salary levels, significantly enhances teacher retention. High job satisfaction and support from administrators and parents further contribute to lower attrition rates, while overwhelming job demands and insufficient support are closely associated with burnout and increased departures. Drawing …

On-Site Estimation Of Total Sugars In Flavored Milk Using A Glucometer, Erwin Oliver V. Fundador, Karyn Thea E. Rivera, Kriza Faye A. Calumba, Noreen Grace V. Fundador

ASEAN Journal on Science and Technology for Development

Sugar has been linked to obesity and chronic diseases. Unfortunately some "healthy products," such as flavored milk, contain high sugar. In the Philippines, such an issue is made worse by local brands not putting nutritional labels on their products. Thus, a cheap, home-based method to measure total sugars should be beneficial. In this paper, we have shown that after incubation with invertase and lactase, a glucometer can be used to measure total sugars in flavored milk on-site. All experiments except the weighing of invertase and lactose were done in a home setting for actual proof of concept. The total sugar …

"The Lover's Confession": A Translation Of John Gower's "Confessio Amantis", Brian Gastle, Catherine Carter, Andrew Galloway

TEAMS Varia

John Gower’s Confessio Amantis (The Lover’s Confession) is one of the most important English works of the fourteenth century, influencing authors from Chaucer to Shakespeare. Within its frame of the lovesick lover’s confession are well over a hundred stories, mainly derived from classical mythology, the Bible, and history which exemplify the Middle Ages serve as moral lessons (exempla) for personal and political behavior. Echoing the octosyllabic line of the original, this is the first complete modern English translation of the entire (33,000-line) poem, including its Latin verses and glosses.

"I’M Not Teaching Them Per Se": Designing And Delivering Asynchronous Undergraduate Online Stem Courses, Regina L. Garza Mitchell, Whitney Decamp, Brian Horvitz, Megan Grunert Kowalske, Cherrelle Singleton

Instruments for Measuring Online Teaching Practices

Although online courses have been a part of academia for nearly 30 years, they are still perceived as “different” than face-to-face instruction. Through in-depth interviews with four instructors, we explored how STEM faculty approach teaching asynchronous online undergraduate STEM courses. The faculty interviewed for this study viewed online courses as “not regular class[es]” and teaching those classes as “not teaching per se.” Each of the instructors had assumptions about what a classroom was and about good instruction, but even for instructors who taught online for multiple years, those assumptions remained grounded in the face-to-face environment. There is a need for …

Developing An Observation Protocol For Online Stem Courses, Brian Horvitz, Whitney Decamp, Regina L. Garza Mitchell, Megan Grunert Kowalske, Cherrelle Singleton

Instruments for Measuring Online Teaching Practices

The use of online instruction for undergraduate STEM courses is growing rapidly. While researchers and practitioners have access to validated instruments for studying the practice of teaching in face-to-face classrooms, analogous tools do not yet exist for online instruction. These tools are needed for quality design and control purposes. To meet this need, this project developed an observational protocol that can be used to collect non-evaluative data for the description, study, and improvement of online, undergraduate STEM courses. The development of this instrument used a sequential exploratory mixed methods approach to the research, design, pilot-testing, refinement and implementation of the …

To Burn Or Not To Burn: Governance Of Wildfires In Australia, Sarah Clement, Ahjond Garmestani, Jo Ann Beckwith, Pele J. Cannon

School of Natural Resources: Faculty Publications

Globally, wildfires are increasing in extent, frequency, and severity. Although global climate change is a major driver and large-scale governance interventions are essential, focusing on governance at smaller scales is of great importance for fostering resilience to wildfires. Inherent tensions in managing wildfire risk are evident at such scales, as objectives and mandates may conflict, and tradeoffs and impacts vary across ecosystems and communities. Our study feeds into debates about how to manage wildfire risk to life and property in a way that does not undermine biodiversity and amenity values in social-ecological systems. Here, we describe a case study where …

Geologists As Colonial Scouts: The Rogers Expedition To Otavi And Tsumeb, Namibia, 1892–1895, Selby Hearth

Geology Faculty Research and Scholarship

From 1892 to 1895, the South West Africa Company (SWACO) expedition led by geologist Matthew Rogers conducted the first geologic mapping in Namibia’s Otavi Mountains, including the now world-famous Tsumeb Mine. This paper uses archival documents from the Rogers expedition to trace his geologic contributions and to illustrate important themes in the relationships between 19th century colonial geologists, Western colonizing governments, Indigenous communities, resource extraction, and corporations. To carry out his mapping, Rogers performed a continuous balancing act between British and German colonial powers and local African leaders. The local leaders and communities he interacted with variously resisted his incursions, …

Cataloguing Minerals, Part One: Historical Cataloguing Practices And The Logics Of Colonialism, Selby Hearth, Carrie Robbins, Marianne Weldon, Aha Anderson, Rosa Bieber-Stanley, April Chernila, Helen Christ, Hannah Cosgrove, Morgan Hanson-Rosenberg, Carly Hill, Maya Hofstetter, Emily Lazo, Izzie Ludlow, Samantha Lyster, Rachel Myers, Jasper Nash, Georgia Reed, Julia Saint- Amour

Geology Faculty Research and Scholarship

Mineral wealth has motivated and funded extractive empires, often at the expense of local communities, workers, natural environments, and public health. Yet those connections are not recorded in traditional mineral catalogues, which divorce specimens from context. This article examines the roots of those omissions and situates mineral cataloguing in the larger body of literature on knowledge organization systems and their relation to power. We examine how colonial ideologies of land and people become entrenched in mineral cataloguing practices, and how this reinforces the ways that contemporary geologists think about their work. We argue that revising mineral cataloguing practices is a …

Crowdsourcing Surveillance, Chaz Arnett

Faculty Scholarship

In Unreasonable: Black Lives, Police Power, and the Fourth Amendment, Devon W. Carbado illuminates how both the spectacular and quotidian forms of racialized terror, brutality, and surveillance—characteristic of enslavement—have shaped the construction of our constitutional order. He argues that the combined social normalization and legal naturalization of racial hierarchy paved the way for the development of slave patrols and other early iterations of policing where incredible acts of violence against Black bodies were made ordinary and essential. He explains how this legacy continues today with Fourth Amendment jurisprudence not simply failing to protect rights but rather licensing police violence …

A free-to-play approach, indicated by a significant hot spot, is adopted by developers focusing on post-purchase revenues through DLC, aesthetic purchases, and in-game transactions. This sailing strategy includes community-centric developers aiming to distribute their games for player engagement rather than profit.

The project illustrates the effectiveness of advanced modeling techniques in handling complex datasets, with significant predictive accuracy reflected by a reduced MSE from 0.3472 to 0.1397. …

Does Path Matter?: A Quantitative Study Examining Mathematics Course-Taking Patterns And Degree Or Transfer Attainment, Jacqueline Kraus

Dissertations of Practice

DOES PATH MATTER: A QUANTITATIVE STUDY EXAMINING MATHEMATICS COURSE-TAKING PATTERNS AND DEGREE OR TRANSFER ATTAINMENT

Abstract

This quantitative study, guided by Bean and Metzner’s (1985) student attrition model, examined whether mathematics course-taking pattern is associated with a students’ chances of attaining degree or transfer at a community college. Six years of student data from a midwestern community college was used. Descriptive statistics of student course-taking patterns highlighted that more full-time and college level students enrolled in mathematics immediately while part-time and developmental level students delayed their enrollment in mathematics coursework. Contradicting assumptions at the midwestern community college under study, it …

A Quantitative Study On The Relationship Between Corequisite Support Courses And College Algebra Success, Kathleen Almy

Dissertations of Practice

Corequisite support courses have been used as an intervention in higher education to improve gateway college math course completion and reduce the time necessary to do so. While a substantial amount of research on the effectiveness of corequisite support exists, it has largely focused on non-STEM courses. This study was designed to further investigate the effectiveness of corequisite support courses but in the context of STEM courses like College Algebra. Specifically, the study explored the role of taking a corequisite version of College Algebra, with and without the consideration of a student’s initial placement, on both the probability of passing …

Female Biology, Jennifer Dever

All USF Faculty Authored Books

Over twenty years ago I developed a course for the upper- level biology major at the University of San Francisco called

Female Biology. This was from what I perceived as a gap in the undergraduate biology curriculum- students were not learning about the evolutionary aspects of being female and studying the specific health-related issues unique to women. The information in the most widely used general biology textbooks written from a male perspective, focuses on research gained from male models by work conducted in male-led laboratories. There still exists a problem with a lack of adequate representation of women in biomedical …

Chemical Strategies For Tailoring Properties Of Nanomaterials Produced By Pulsed Laser Interaction In Liquid Environments, Katharine M. Tibbetts

Chemistry Publications

Interactions of intense ultrashort laser pulses with liquid media and at solid-liquid interfaces produce plasmas with high densities of reactive chemical species that promote the formation of nanomaterials. This work discusses the current understanding of laser-induced chemical reactions in aqueous medium involving hydrated electrons and hydroxyl radicals, and the effects of chemical additives on these reactions. Two chemical strategies are presented for controlling the composition of the laser-induced plasma and nanomaterial properties. First, adding chemical scavengers of hydroxyl radicals will be shown to inhibit metal oxidation, enabling the synthesis of ligand-free Ag and Au-Ag alloy nanoparticles by reduction of Au …
