University of South Florida (USF) M3 Publishing

OVERVIEW

The technology and the rise of Web 2.0. enabled the meteoric rise of peer-to-peer (P2P) platforms facilitating transactions and consequential establishment of the sharing economy concept. This accelerated technological change has led to new dynamics in cities and tourist destinations such as over-tourism with the so-called arise of the sharing economy significantly fueling it. The main purpose of our chapter is to systematically review this dual aspect of technological impacts on tourism. On the one hand, we review the technological aspects that underpin the development of the sharing economy and consequential over-tourism in destinations. On the other hand, we …

Scorched Border Litigation, Briana Beltran, Beth Lyon, Nan Schivone

Cornell Law Faculty Publications

Each year, employers bring hundreds of thousands of temporary foreign workers into the United States only to return them to their communities of origin when their visas end. During their short months working in the United States—whether in agricultural fields, hotels, traveling carnivals, or private homes—many of these workers experience violations of their rights: wages are stolen, injuries are ignored, and those who complain are punished on the spot or sent home.

Temporary foreign workers who choose to file a lawsuit to vindicate their rights typically do so once they are no longer in the United States, often litigating from …

Gratitude, Elizabeth Reimer

Master's Theses or Doctor of Nursing Practice

Gratitude is a concept that has impacted my life in an enormous way. Along with being a key element in this exhibition, it blends in well with me as a person and my personal life. I am extremely blessed to have the heritage that I do from both sides of my family. Gerdy’s Community Market was built on that same family concept. The gratitude celebrated after a harvest with family and community is the foundation that Gerdy’s was built on. I wanted each of the pieces I designed to support that same foundation and highlight the culture surrounding my family’s …

Ecological Controls On The Campanian Distribution Of Hesperornis (Aves: Hesperornithiformes) In The Western Interior Seaway, Blake Chapman

Master's Theses or Doctor of Nursing Practice

The epicontinental Western Interior Seaway (WIS) of Late Cretaceous North America provided a unique marine habitat for cephalopods, fish, marine reptiles, and the foot-propelled diving seabird Hesperornis. While several predator-prey relationships among Hesperornis or other hesperornithiforms and other WIS animals have been hypothesized based on gut contents, bite marks, and coprolites/colonites, ecological relationships have not been quantitatively tested. Paleontological species distribution modeling (SDM) studies have focused on extinct non-marine taxa and marine invertebrates, with only two marine vertebrate studies of extant taxa. Here, two SDM methods were used to test the influence of vertebrate faunas, sedimentary rock type, paleogeography, …

Faculty Publications

This review is a comprehensive summary of treatment options for pregnant patients with less common bacterial, fungal, and viral infections. It offers guidance to clinicians based on the most recently published evidence-based research and expert recommendations. A search of MEDLINE (inception to March 2021) and the CDC website was performed. Liposomal amphotericin B is the preferred therapy for cryptococcosis, histoplasmosis, oesophageal candidiasis, and coccidioidomycosis, especially during the first trimester due to teratogenic concerns with azole antifungals. For oral candidiasis, clotrimazole troches or miconazole mucoadhesive buccal tablets are recommended. A β-lactam antimicrobial is preferred over doxycycline for various manifestations of Lyme …

Multi-Label Classification On Locally-Linear Data: Application To Chemical Toxicity Prediction, Xiu Huan Yap

Browse all Theses and Dissertations

Computational models may assist in identification and prioritization of large chemical libraries. Recent experimental and data curation efforts, such as from the Tox21 consortium, have contributed towards toxicological datasets of increasing numbers of chemicals and toxicity endpoints, creating a golden opportunity for the exploration of multi-label learning and deep learning approaches in this thesis. Multi-label classification (MLC) methods may improve model predictivity by accounting for label dependence. However, current measures of label dependence, such as correlation coefficient, are inappropriate for datasets with extreme class imbalance, often seen in toxicological datasets. In this thesis, we propose a novel label dependence measure …

Developing A Nomological Network To Incorporate Learned Helplessness Into Industrial-Organizational Psychology, Nicholas Kovacs

Browse all Theses and Dissertations

Employees are facing personal traumas, higher stress, and work pressures that are likely to result in both short- and long-term impacts. To mitigate these negative impacts, organizations should focus on applying research related to employees’ responses to trauma and stress. Learned helplessness, which is well-established within clinical psychology and less established within the industrial-organizational literature, occurs as a direct response to perceived control over trauma and could thus relate to the ability to overcome trauma. In relation to control-related constructs, industrial-organizational researchers have focused on resilience, hardiness, and work locus of control (LOC). However, each of these constructs account for …

The Effect Of Endogenous Ligands Of The Aryl Hydrocarbon Receptor On Antibody Expression In A Human B-Cell Model, Valerie Benedict

Browse all Theses and Dissertations

Small changes in antibody expression have broad impacts on human health and disease. An environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induces profound immune suppression in animal models in an aryl hydrocarbon receptor (AhR)-mediated fashion. In a human Burkitt's lymphoma cell line (CL-01), TCDD inhibited IgG secretion and differentially impacted Ig heavy chain expression. In addition to TCDD, the AhR has several endogenous, dietary, and bacterial ligands such as 6-formylindolo[3,2-b]carbazole (FICZ) and indole, which are present within the human body at varied concentrations (0.30 mM- 6.64 mM). Both FICZ (100 nM) and indole (100 µM) significantly reduced IgG secretion. Overall antibody secretion is …

Rap1a Overlaps The Age/Rage Signaling Cascade In Type 2 Diabetes Mellitus, Stephanie Burr

Electronic Theses and Dissertations

Diabetic individuals have an increased risk for developing cardiovascular disease due to stiffening of the left ventricle, which is thought to occur, in part, by increased AGE/RAGE signaling. Advanced glycation end products (AGEs) accumulate within the body over time, and under hyperglycemic conditions, the formation and accumulation of AGEs is accelerated. AGEs exert their effect by binding to their receptor (RAGE) and can induce myofibroblast differentiation, oxidative stress, cell-extracellular matrix contraction, and cell migration. Previous findings from our lab have demonstrated that preventing the production of Rap1a, a Ras-like GTPase signaling protein, in cardiac fibroblasts will decrease type 2 diabetes …

Subcutaneous Delivery Of Albumin, Vy Nguyen

Electronic Theses and Dissertations

An increasing number of protein drugs are used in the clinic to treat a broad range of diseases. However, because of their large molecular sizes and high hydrophilicity, protein drugs are not orally bioavailable, which commonly require intravenous, intramuscular or subcutaneous injection. Thermosensitive polymers have been widely investigated as in situ depots for sustained drug release delivered through subcutaneous route.Albumin is the most abundant proteins in bloodstream. It has long half-life (19 days in human) and plays important roles such as acting as carrier for fatty acids, amino acids, waste products and medical compounds. Albumin has been studied for decades …

Effects Of Nonnative Phonotactic Constraints On The Perception Of Nasal-Initial Consonant Clusters, Msafiri Otonya

Electronic Theses and Dissertations

This study examines the effects of non-native phonotactic constraints on the perception of nasal-initial consonant clusters (NICC), specifically whether native English speakers can perceive NICC as accurately as native Swahili speakers. The ABX task was conducted over Zoom to test L1 English speakers (N=12) and L1 Swahili speakers (N=12). Stimuli with four conditions were used: 1) The stimuli had one of the three nasal sounds (/m/, /n/, and /?/) in word-initial consonant clusters; 2) The stimuli had NICC composed of a nasal sound followed by either a voiced or voiceless consonant; 3) The consonant clusters were composed of sounds that …

This Garden: Oysters And Place Along Florida's Forgotten Coast, Annemarie Anderson

Electronic Theses and Dissertations

THIS GARDEN is an audiovisual installation that tells the story of oyster farmers and place in Spring Creek, Florida. I use the oral history interviews and documentary photography I made there to explore aquaculturists’ deep relationship with the surrounding environment. To these farmers, the bay is a garden. They work within those often-unpredictable waters to cultivate new life. This accompanying thesis builds a chronological narrative of oyster aquaculture industry along Florida’s Forgotten Coast. It connects Florida’s burgeoning aquaculture industry to the long history of human involvement along the Gulf Coast in commercial fishing and wild harvest oyster operations. Lastly, I …

Structured To Fail: Lessons From The Trump Administration's Faulty Pandemic Planning And Response, Alejandro E. Camacho, Robert L. Glicksman

GW Law Faculty Publications & Other Works

The Trump Administration’s response to the COVID-19 pandemic is a stark reminder that poorly designed government can be a matter of life and death. This article explains how the Administration’s careless and delayed response to the crisis was made immeasurably worse by its confused and confusing reallocation of authority to perform or supervise tasks essential to reducing the virus’s ravages.

After exploring the rationale for and impact of prior federal reorganizations responding to public health crises, the article shows how a combination of unnecessary and unhelpful overlapping authority and a thoughtless mix of centralized and decentralized authority contributed to the …

The Radical Uncertainty Of Free Exercise Principles: A Comment On Fulton V. City Of Philadelphia, Ira C. Lupu, Robert W. Tuttle

GW Law Faculty Publications & Other Works

This paper addresses the decision in Fulton v. City of Philadelphia (June 17, 2021), in which a unanimous Supreme Court upheld a claim under the First Amendment’s Free Exercise Clause by Catholic Social Services (CSS) against the City. CSS had objected on religious grounds to screening same-sex married couples as prospective foster parents, despite a provision in its contract with the City that prohibited such discrimination. Every Justice voted to uphold the Free Exercise Claim. Only three Justices, however, supported the overruling of the Court’s highly controversial decision in Employment Division v. Smith (1990), which insulated religion-neutral, generally applicable policies …

In Search Of The Presumption Of Regularity, Aram A. Gavoor, Steven Platt

GW Law Faculty Publications & Other Works

The presumption of regularity is an imprecise quasi-deference principle that federal courts apply in varying ways to presume federal officers and employees lawfully and consistently discharge their official duties. The presumption gained national significance during the Trump Administration in several key cases in which it was implicated, but never described by the Supreme Court. While the literature and judicial opinions have invoked the presumption, there has been sparse scholarly accounting for its contours, value, and legitimacy. This Article is the first to trace the contemporary domain of the presumption and its applications from its pre-Founding Era source and normatively-recognized 1926 …

The George Washington University has been redressing this problem through a research initiative focused on such buy-and-hold stock …

Prevalence And Exacerbation Of Asthma Within Two Counties In Eastern Kentucky, Rachid Souleye

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background: Central Appalachia residents have one of the highest rates of serious respiratory diseases in the nation. Appalachian Kentuckians are 50% more likely to be diagnosed with adult asthma compared to the overall U.S. population. Yet, few epidemiologic studies have assessed risk factors for respiratory disease in this population. Using a community-based approach, the investigators of the Mountain Air Project (MAP), one of the largest adult cohorts from two disadvantaged communities in Central Kentucky, collected data to estimate the prevalence of asthma and assess various socioeconomic and environmental risk factors to determine their effect on asthma.

Methods: A cross-sectional epidemiologic …

Rabies In Kentucky From 1989-2020: A Case For Surveillance, Sarah Jane Robbins

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The Kentucky rabies reporting system includes data from five laboratories and provides an account of suspected rabies reports since 1989. Over 35,000 suspected cases are used to estimate rabies incidence temporally and spatially. Recommendations to the current rabies reporting methodologies are presented through proposed innovations of a standard, electronic reporting form. Given the multiple sources of data, the reporting system lacks standardization and comprehensive information about suspected rabies events, resulting in limited epidemiological capabilities; and data issues that prevent its use as a surveillance system. These issues are a limiting factor in rabies elimination; but a driving factor in over-testing, …

Comparison Of Differential Effects Of Interpolated And Intermittent Reinforcement On Extinction Resistance: A Simulated Study, Cara D. Baxter

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Schedules of reinforcement explain when a reinforcer may be delivered. Among the different schedules exists continuous (CRF), intermittent (INT), and extinction (EXT). When employing a CRF, reinforcement is delivered following every occurrence of the target response. An INT schedule includes varying the delivery of reinforcement. While both of these schedules include the delivery of reinforcement, EXT means that reinforcement is no longer delivered for the target response (Lee & Belfiore, 1997). Studies have shown that behaviors may be less resistant to extinction if moved from an INT schedule to a CRF schedule than if EXT followed the INT schedule alone. …

Factors Influencing Mare Milk And Foal Gastrointestinal Health, Morgan Brewer Pyles

Theses and Dissertations--Animal and Food Sciences

Foals are born lacking a functional microbial community in their gastrointestinal tract (GIT). However, these microbes quickly colonize after birth. Factors influencing the process of microbial colonization and health of the foal’s gastrointestinal tract, such as milk yield and composition, are not well understood. Milk contains non-lactose carbohydrates termed “oligosaccharides”, which serve as prebiotics in human neonates and may serve a similar function in foals. Three animal studies were conducted to evaluate factors influencing mare milk and digestive health in the foal. In experiment 1, bacteria were enumerated and identified in foal feces and the utilization of different carbohydrates by …

The Effect Of Endophyte-Infected Tall Fescue Seed Consumption On Gut And Satiety Hormones Related To Intake Regulation In Holstein Steers, Mindy Elizabeth King

Theses and Dissertations--Animal and Food Sciences

Cattle consuming endophyte-infected tall fescue (E+) typically experience a syndrome termed fescue toxicosis which is thought to be caused by ergot alkaloids produced by the endophyte. The most abundant alkaloid, and considered the most likely cause of the syndrome, is ergovaline (ERV). During fescue toxicosis, a decrease in ADG is observed which is likely due to the decrease in DMI commonly observed in animals consuming E+ compared to animals consuming non-endophyte-infected tall fescue (E-). However, the cause of the decrease in intake is not well elucidated. Many physiological responses control feed intake including, but not limited to, physical, neural, metabolic, …

Isolation Box Test (Ibt) And Dairy Calf Personality Traits Relationship With Performance Through Weaning, Megan Marie Woodrum Setser

Theses and Dissertations--Animal and Food Sciences

Personality tests are utilized to characterize individual differences in personality traits across species. Currently, there is no objective personality test that can be implemented on-farm to measure personality in dairy calves. Measuring personality of youngstock in the dairy industry may allow producers to utilize information on individual differences for management decisions and limit the investment in unfit individuals. The isolation box test is a personality test that has potential to be adapted and utilized for dairy calves. The main objective of this thesis is to develop, validate, and utilize an isolation box test for use on-farm in dairy calves. More …

The Relationship Between Insomnia, Sleep Continuity Disturbance, Sleep-Related Daytime Dysfunction, Problem Endorsement, And Aging In A Community-Based Sample, Julia T. Boyle

PCOM Psychology Dissertations

Although older adults experience greater difficulty initiating sleep, maintaining sleep, or waking up earlier than intended, they are less likely to report that they perceive this to be a problem. The discordance between sleep disorder symptoms and the reported perception that they are troubling is unusually prevalent among older adults. This may be problematic, in that individuals who do not perceive their sleep continuity disturbances (SCDs; difficulty falling asleep, staying asleep, or waking up earlier than intended) to be problems are less likely to seek treatment. Untreated SCD has been shown to be a risk factor for the development or …

The Role And Implications Of Executive Functions During The Transition To Middle School, Susan Niznik

PCOM Psychology Dissertations

The current study analyzed the relationship between executive functions and academic performance in middle school. In particular, this study analyzed the relationship between BRIEF Index and Scale scores that were compiled on a group (N = 54) of seventh graders by two seventh-grade ELA teachers and the students’ final grades in ELA, Math, Science, and Social Studies. The results showed statistically significant correlations between most of the BRIEF Indexes and Scales and the final grades, with the Metacognitive Scales showing the highest correlations. In contrast, the results showed much higher incongruence index values than expected, given the high correlations that …

Hate Speech On Social Media: Content Moderation In Context, Richard A. Wilson, Molly Land

Faculty Articles and Papers

For all practical purposes, the policy of social media companies to suppress hate speech on their platforms means that the longstanding debate in the United States about whether to limit hate speech in the public square has been resolved in favor of vigorous regulation. Nonetheless, revisiting these debates provides insights essential for developing more empirically-based and narrowly tailored policies regarding online hate.

First, a central issue in the hate speech debate is the extent to which hate speech contributes to violence. Those in favor of more robust regulation claim a connection to violence, while others dismiss these arguments as tenuous. …
