The Impact Of A Division I Volleyball Season On Jumping Performance, Joshua R. Pascal

College of Graduate Studies: Theses & Dissertations

Previous research has been conducted on different performance metrics in collegiate athletes in various sports, including volleyball. These metrics include strength, speed, power output, and jump height. However, little research has examined changes in seasonal jumping performance in volleyball athletes on a weekly basis. Purpose: To examine how Division I Volleyball jumping performance is affected by a competitive season. Methods: 11 female volleyball athletes from one NCAA Division I institution wore VERT sensors during practices for the entire 15-week competitive season. The athletes also completed countermovement Jump Mat testing on the first practice of the week, with the exception of …

Predator-Based Selection And The Impact Of Edge Sympatry On Components Of Coralsnake Mimicry, Lauren E. Wilson

College of Graduate Studies: Theses & Dissertations

Studying warning coloration and mimicry is an effective way to understand predator-driven selection and phenotypic diversity. The presence (sympatry) or absence (allopatry) of a toxic model plays a role in shaping mimetic phenotypes. However, the impact of edge sympatry and allopatry on predation of mimetic phenotypes is not well understood. We studied coralsnake mimicry to test how edge sympatry and allopatry affect predation on mimetic phenotypes. Specifically, we tested 1) if overall attack rates varied with edge sympatry of coralsnakes 2) which color patterns conferred a fitness advantage 3) which specific mimetic signal components are important in driving predatory attacks …

Scaling And Ecological Relationships In The Visual Ecology Of Sharks, Brianna Hall

College of Graduate Studies: Theses & Dissertations

Adaptations of visual systems, such as acuity, sensitivity, and eye size can be used to infer the relative importance of vision to an organism. The high metabolic cost of visual system development and maintenance suggests that large relative eye size (as it relates to body length) may have a significant ecological or evolutionary role. Elasmobranchs are morphologically diverse and inhabit a wide range of marine and freshwater niches. As energetic and ecological demands shift over time, several species occupy different predatory niches across their lifetime, yielding a large array of visual habitats. Additionally, eye size changes with body length allometrically, …

Physiological Response Of Elasmobrachs During Propofol Immersion, Matthew Levendosky

College of Graduate Studies: Theses & Dissertations

Sensory experiments require anesthesia so the animal is immobilized, however fish anesthetics have shown to depress sensory responses. Newer anesthetics may offer similar anesthetic relief, but differ in means of action so sensory responses may be unaffected. Propofol has been used intravenously on small elasmobranchs but may provide prolonged effects if used as an immersion anesthetic. Objectives of this study were 1. Determine appropriate concentration of anesthetic to minimize induction and recovery for animals anesthetized at a surgical plane of anesthesia and 2. Measure physiological response of the pupil to light stimuli during anesthetic immersion. To address these objectives, I …

The Relationship Between Servant Leadership And Teacher Retention And Student Achievement, David Earl Murphy

College of Graduate Studies: Theses & Dissertations

This non-experimental quantitative study aimed to determine if servant leadership influenced teacher retention or student achievement and if teacher retention influenced student achievement. This study’s respondents were 145 middle and high school teachers within a contiguous rural region of the Southeastern United States. Survey responses were received and analyzed during the late summer of 2020. Three research questions guided this study: Does servant leadership [high, low] influence teacher retention intention; What is the effect of servant leadership [high, low] on student achievement by categorical population groups as identified by the GaDOE; and lastly, What is the effect of teacher retention …

Attitude Formation And Malleability In Response To Visual Cues And Counterattitudinal Information, Tyler W. Mueller

College of Graduate Studies: Theses & Dissertations

BACKGROUND: The purpose of this research is to investigate how individuals form attitudes based on the appearance of another person and how malleable those attitudes are when the individual is presented with new information about the other person. The predicted effect from this study was that participants would form attitudes about another person's agreeableness based on visual information and that when presented counterattitudinal information would be more likely to change attitudes than information that matches their initial attitude. It was also expected that negative first impressions would be harder to change. METHOD: Participants (N = 109) were presented one …

A Phenomenological Exploration Of Principals' Influence On Teacher Attrition, Kellie E. Gebhardt

College of Graduate Studies: Theses & Dissertations

ABSTRACT

Classroom teachers' decisions to leave the profession negatively affect the educational experience of the students, burden the remaining teachers, and drain school districts of funds that should go to students but instead are spent on recruiting and training. This phenomenological study examined the experiences of former classroom teachers to determine the role their school principals may have played in their decisions to leave the profession. Ten former elementary school teachers from South Carolina participated in the study. The researcher collected data using interviews; a semi-structured interview protocol was created from current literature and designed to align with the research …

Factors Associated With Hiv Testing In Liberia: Findings From The 2013 Demographic Health Survey, Miatta M.E. Dennis

College of Graduate Studies: Theses & Dissertations

Human immunodeficiency virus (HIV) is among the world’s most serious challenges. The African region is severely affected with nearly one in 25 adults being HIV infected –accounting for over two-thirds of HIV infected people worldwide. In 2013, approximately three in four men and half of women aged 15-49 had never been HIV tested. In 2018, over 7,000 Liberians were HIV positive. Increasing HIV testing rates is the primary step to reducing HIV infection rates. This study examines factors associated with HIV testing behavior among Liberians using the Knowledge Attitude Behavior (KAB) model as a conceptual framework. The 2013 Liberia Demographic …

Association Rules Patterns Discovery From Mixed Data, Welendawa Acharige Charith A. Elson

College of Graduate Studies: Theses & Dissertations

Finding Association Rules has been a popular unsupervised learning technique for dis covering interesting patterns in commercial data for well over two decades. The method seeks groups of data attributes and their values where their probability density of these attributesattherespectivevaluesismaximized. Therearecurrentlywell-establishedmeth ods for tackling this problem for data with categorical (discrete) attributes. However, for the cases of data with continuous variables, the techniques are largely focusing on cate gorizing continuous variables into intervals of interest and then relying on the categorical data methods to address the problem. We address the problem of finding association rules patterns in mixed data by …

Assessing Hotel Employee Knowledge On Risk Factors And Risk Management Procedures For Microbial Contamination Of Hotel Water Distribution Systems, Brandon Leftwich

College of Graduate Studies: Theses & Dissertations

Background: Compromised hotel water supply lines by neglect or by physical and structural damage can lead to exposure of harmful pathogens to guests and staff. To reduce the risk of having contaminated water in a hotel plumbing system, some facilities may incorporate a water safety plan (WSP). WSPs are not mandatory for hotels in many US states, including the state of Georgia. As such, many hotel personnel are uninformed of WSPs and the precautions to take if their hotel water system is compromised. The purpose of this study was to identify hotel personnel’s knowledge and practices of WSPs through a …

Can Farmers And Bats Co-Exist? Farmer Attitudes, Knowledge, And Experiences With Bats In Belize, Hannah G. Shapiro, Adam S. Willcox, Mallory Tate, Emma V. Willcox

Human–Wildlife Interactions

Bats (Chiroptera) are often viewed negatively by the public. Negative public perceptions of bats may hinder efforts to conserve declining populations. In Belize, the presence of vampire bats (Desmodus rotundus and Diphylla ecaudata) exacerbates the potential for conflicts with humans because of the increased rabies transmission risks. To mitigate these risks, the Belize government provides farmers with assistance to trap and remove vampire bats. In June 2018, we surveyed farmers (n = 44) in and adjacent to the Vaca Forest Reserve in Belize to learn more about their attitudes, knowledge, and experiences with bats. This information may …

Talking Trash In The Big Apple: Mitigating Bird Strikes Near The North Shore Marine Transfer Station, Stephan J. Beffre, Brian E. Washburn

Human–Wildlife Interactions

Anthropogenic activities that concentrate wildlife near airports increases the risk of wildlife–aircraft collisions. Placing waste management facilities, natural areas, golf courses, and other landscape features near airports have the potential to attract wildlife hazardous to aviation. We conducted a 3-year study (March 2013–February 2016) to determine if the implementation of a Wildlife Hazard Mitigation Program (WHMP) would influence the bird use of a waste transfer station located near LaGuardia Airport, New York City, New York, USA. We conducted wildlife surveys during 3 phases: (1) no mitigation program and no waste transfer station, (2) active mitigation and no waste transfer station, …

Using Environmental Dna To Detect Estuarine Crocodiles, A Cryptic-Ambush Predator Of Humans, Alea Rose, Yusuke Fukuda, Hamish A. Campbell

Human–Wildlife Interactions

Negative human–wildlife interactions can be better managed by early detection of the wildlife species involved. However, many animals that pose a threat to humans are highly cryptic, and detecting their presence before the interaction occurs can be challenging. We describe a method whereby the presence of the estuarine crocodile (Crocodylus porosus), a cryptic and potentially dangerous predator of humans, was detected using traces of DNA shed into the water, known as environmental DNA (eDNA). The estuarine crocodile is present in waterways throughout southeast Asia and Oceania and has been responsible for >1,000 attacks upon humans in the past …

Use Of Roadside Deer Removal To Reduce Deer–Vehicle Collisions, John C. Kilgo, John I. Blake, Tracy E. Grazia, Andy Horcher, Michael Larsen, Thomas Mims, Stanley J. Zarnoch

Human–Wildlife Interactions

Identification of management tools to reduce the incidence of deer–vehicle collisions (DVCs) is important to improve motorist safety. Sharpshooting to reduce white-tailed deer (Odocoileus virginianus; deer) along roads has proven successful in urban situations but has not been evaluated in undeveloped areas. We used a before-after-control-impact (BACI) design to evaluate the use of sharpshooting to reduce DVCs along roads on the uninhabited U.S. Department of Energy’s Savannah River Site, South Carolina, USA, during 2011–2017. We removed 242 deer from 4 treatment roads during 2015 and 2016, with 2-year removal rates per road averaging 5.0 deer/km of road (range …

After Decades Of Suburban Deer Research And Management In The Eastern United States: Where Do We Go From Here?, Paul D. Curtis

Human–Wildlife Interactions

State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges as they try to meet the desires of diverse stakeholder groups. Although deer management programs in urban areas differ somewhat in every state, effective management …

Population Increases Of Large Birds In North America Pose Challenges For Aviation Safety, Richard A. Dolbeer

Human–Wildlife Interactions

There is a strong correlation between bird mass and the likelihood of aircraft damage during a bird–aircraft collision. Thus, the U.S. Federal Aviation Administration (FAA) has established airworthiness standards related to bird mass for engines, airframes, and windshields. Most standards use large (1.8 kg) and medium (1.1 kg) birds as benchmarks (the empennage and certain large turbofan engines use a 3.6-kg bird). There are 20 large (≥1.8 kg) and 16 medium (1.1–1.7 kg) bird species in North America with ≥20 strikes reported for civil aircraft (FAA National Wildlife Strike Database), 1990 to 2018. I analyzed the population changes of these …

Serum Chemistry Values In Wild Black Vultures In Mississippi, Usa, Fred L. Cunningham, Sherman W. Jack, Amanda R. Deese, Eric R. Wengert, Kyle Van Why, Carla L. Huston, Scott Lemmons, Richard B. Minnis

Human–Wildlife Interactions

Vultures (Cathartidae and Accipitridae) play an important role in ecosystem balance by rapidly disposing animal carcasses and thus preventing the potential spread of pathogens. Blood chemistry values provide a means of assessing the health of wildlife and wild animal populations; however, there are significant differences in chemistries among species and when comparing captive and free-living New and Old World vultures. In 2007, we collected blood serum from 30 female and 14 male wild, healthy black vultures (Coragyps atratus) live-trapped by the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services from a power substation in …

Using Bioenergetics And Radar-Derived Bird Abundance To Assess The Impact Of A Blackbird Roost On Seasonal Sunflower Damage, Bonne A. Clark, Page E. Klug, Phillip M. Stepanian, Jeffrey F. Kelly

Human–Wildlife Interactions

Methods aimed at reducing avian damage to agricultural crops are routinely implemented in situations where efficacy can be assessed by quantifying blackbird (Icteridae) abundance relative to environmental variables and extrapolating to ensuing crop damage. Concomitantly, Weather Surveillance Radar (WSR) data may have potential to enhance crop damage mitigation through improved monitoring of nuisance wildlife populations. We used WSR to derive daily abundance estimates of blackbirds at a fall roost in North Dakota, USA from 2012 to 2019. We integrated these estimates with previously developed bioenergetics-economic models to estimate local sunflower (Helianthus annuus) damage. The greatest losses usually occurred …

Viewing Bornean Human–Elephant Conflicts Through An Environmental Justice Lens, Elena C. Rubino, Christopher Serenari, Nurzhafarina Othman, Marc Ancrenaz, Fauzie Sarjono, Eddie Ahmad

Human–Wildlife Interactions

Sabah, on the northeastern corner of Borneo, is concurrently Malaysia’s largest producer of oil palm (Elaeis guineensis) and home to the endangered Bornean elephants (Elephas maximus borneensis; elephants). Concomitantly, Sabah has been experiencing increasing and unsustainable human–elephant conflicts (HECs), which have not been thoroughly investigated from a human dimensions standpoint. To address this void, in March 2019, we conducted semi-structured interviews with 37 villagers located in the Sabah districts of Lahad Datu, Tawau, and Telupid to investigate villager cognitions regarding elephants, behaviors toward elephants, the formal and informal village institutions employed to mediate HECs, and the …

Enabling The Best Interests Factors, Adrián E. Alvarez

Faculty Publications

(Excerpt)

For over a century, state courts and other child welfare agencies in the United States have been applying the “best interests of the child standard” to all decision-making concerning children. The standard is also enshrined within the UN Convention on the Rights of the Child (CRC)—a treaty that every nation in the world has ratified except the United States. Notwithstanding its widespread adoption in family law, the standard is, with only a few exceptions, noticeably missing from American laws and policies pertaining to children in the immigration system.

There is a rich literature arguing that children should enjoy special …

Gig Workers As Essential Workers: How To Correct The Gig Economy Beyond The Covid-19 Pandemic, Miriam A. Cherry, Ana Santos Rutschman

Faculty Publications

(Excerpt)

During the early stages of the COVID-19 pandemic in 2020, estimates suggest that approximately forty percent of U.S. workers shifted to working remotely from home. But for many gig workers, who performed grocery shopping for Instacart, delivered food and restaurant meals for DoorDash, or who picked up and delivered packages for Shipt, they were working in person and busier than ever. In fact, many of these gig jobs were considered "essential work," and the rules of state lockdowns across the country classified gig workers as "essential workers."

The Right Family, Noa Ben-Asher, Margot J. Pollans

Faculty Publications

The family plays a starring role in American law. Families, the law tells us, are special. They merit many state and federal benefits, including tax deductions, testimonial privileges, untaxed inheritance, and parental presumptions. Over the course of the twentieth century, the Supreme Court expanded individual rights stemming from familial relationships. In this Article, we argue that the concept of family in American law matters just as much when it is ignored as when it is featured. We contrast policies in which the family is the key unit of analysis with others in which it is not. Looking at four seemingly …

Sentencing Disparities And The Dangerous Perpetuation Of Racial Bias, Jelani Jefferson Exum

Faculty Publications

This Article addresses the role that racial disparities— specifically sentencing disparities—play in perpetuating the racial bias that increases the daily danger of living as a Black American in the United States. As documented in the news and by sometimes humorous internet memes, White people have called the police many times to report Black people who were simply living as any other American. This trend highlights the manner in which the U.S. criminal justice system’s racial inequities feed into biased beliefs about Black criminality. This Article argues that instead of tackling implicit bias as a means to fight sentencing and other …

You Shall Not Pass! How The Dublin System Fueled Fortress Europe, Ashley B. Armstrong

Faculty Publications

This Article examines the recent proliferation of walls and fences in Europe, fueled by the Dublin Regulation’s failure to distribute responsibility for asylum seekers equitably among European states. Legal scholarship does not lack literature bemoaning the failures of the E.U.’s Dublin Regulation—which dictates, generally, that the country where an asylum seeker first enters the E.U. is responsible for processing his or her claim for protection. Yet scholarship on border walls and fences, and what induces European states to construct them, is not prominent in the literature. The critiques lodged against the Dublin Regulation have primarily focused on its futility and …

Backdoor Purposivism, Anita S. Krishnakumar

Faculty Publications

It has become standard among statutory interpretation commentators to declare that, “We are all textualists now.” The comment stems from the observation that in the modern, post-Scalia era, all of the Justices on the U.S. Supreme Court pay significant attention to statutory text when construing statutes and, relatedly, that legislative history use by the Court as a whole has declined since its heyday in the 1970s. The account of textualism’s triumph is so prevalent that some scholars have declared purposivism—or at least traditional purposivism—essentially defunct. Two prominent textualist scholars in particular have suggested that there is a “new purposivism” at …

The Power Of A Positive Tweet, Patricia G. Montana

Faculty Publications

(Excerpt)

I am not naively suggesting that all we need are more positive tweets to solve the inequity problems that still plague many law schools’ treatment and advancement of legal writing faculty. But I do wonder whether more positive tweets from administrators, tenured colleagues, and others can help (and more instantaneously) spread positive feelings, heal past harms, build relationships, forge new connections, and ultimately help create more opportunities for success.
