The Effects Of Various Modes Of Feedback On Preferred Ipod Listening Levels, Justine A. Mcdermott

Dissertations, 2014-2019

The current study was conducted in an effort to promote safe listening habits of personal media player device users. Devices such as the iPod are known to have high output capacities well within the range of potentially hazardous sound levels, thus there is a concern that personal listening may pose a risk to hearing. Intuitive and real-time feedback representing the risk of hearing damage based on selected Preferred Listening Levels (PLLs) was provided to subjects they listened to an iPod. Objective: To provide listeners with tools to judge ‘what is too loud’ (and potentially damaging to hearing) so that they …

Cycling Time Trial Performance Is Not Enhanced By Either Whey Protein Or L-Alanine Intake During Prolonged Exercise, Adam B. Schroer

Masters Theses, 2010-2019

Previous studies have reported that adding protein (PRO) to a carbohydrate (CHO) solution can enhance endurance performance. This ergogenic effect may be a function of additional calories from supplemental protein/amino acids, but this thesis has not been directly examined. Additionally, L-alanine (ALA) is readily oxidized when provided during exercise; the impact that this has on metabolism and prolonged endurance performance is unknown. The purpose of this investigation was to assess performance and various cardiovascular and metabolic outcomes during prolonged cycling, to independently gauge the efficacy of whey PRO hydrolysate and ALA supplementation. Eight trained male and female cyclists (age: 22.3±2.0 …

Effects Of Carbohydrate + Protein Co-Ingestion During And Following Exercise On Cardiovascular Adaptations And Exercise Tolerance During Intensified Cycle Training, Justin Faller

Masters Theses, 2010-2019

Introduction: This study investigated the effects of carbohydrate and protein (CHO+Pro) supplementation during intensified training on cardiovascular adaptations and cycling performance. Methods: Five cyclists (VO2peak = 62.6 ± 10.7 ml/kg/min) performed two 27-day training protocols while receiving either CHO or CHO+Pro supplements. The exercise protocols consisted of 7 days of normal training (NT), 10 days of intensified cycle training (ICT; 100% increase in average training duration versus NT), and 10 days of reduced volume training (RVT; reduction in training duration to 60% of NT). Performance was assessed by a 30-km time trial following 120 min of constant-load cycling and VO2peak …

System Dynamics Modeling Study Of The Possibility Of Endemic Measles In The State Of Virginia, Ivan W. Gowe

Masters Theses, 2010-2019

After an effective vaccine was widely available, measles incidence fell by 98%. Immunization programs and surveillance systems in the United States (US) are so successful there has been no endemic spread since 2000. The threat from measles lies in its high infectivity, an asymptomatic infectious state that lasts an average of four days and the decreasing popularity of vaccination. The lack of first-hand experience with the infection (due to immunization) has caused some to wonder if the vaccine is necessary. Herd immunity threshold is a measure of the fraction of immune individuals present in a population to keep disease reproduction …

Metabolic Engineering Of Flavonoid Biosynthesis In Scutellaria Lateriflora Hairy Roots By Ectopic Expression Of The Atmyb12 Transcription Factor, Tianhong Yang

Student Theses and Dissertations

American skullcap (Scutellaria lateriflora), a perennial herb native to America, is rich in specialized metabolites that have shown various biological activities. In particular, the flavonoids wogonin, baicalein and baicalin have proven anticancer properties in vitro. However, the regulatory mechanisms and biosynthetic steps leading to these specialized metabolites have not been elucidated. To address this issue, hairy root cultures of S. lateriflora expressing the flavonoid-specific transcription factor AtMYB12 from Arabidopsis thaliana were developed using Agrobacterium rhizogenes ATCC 15834 containing a binary vector harboring the AtMYB12 cDNA under the control of the SuperP:TEV expression system. In this study, three AtMYB12 transgenic hairy …

Partial Incubation, Hatching Asynchrony, And Sibling Aggression In The Red-Shouldered Hawk (Buteo Lineatus), Sara Johnson Miller

Student Theses and Dissertations

I used video monitoring to quantify egg-laying intervals, partial incubation, hatching asynchrony, feeding rates, sibling aggression, and causes of mortality or nest failure in a suburban population of Red-shouldered Hawks (Buteo lineatus). The egg-laying interval and parents' partial incubation behavior during egg-laying resulted in a significant correlation between the sum of incubation time during egg-laying and the hatching span (r2 = 0.83, p <0.0001). Hatch rank was the most significant predictor for both the amount of food consumed and the number of aggressive acts displayed by a nestling. First-hatched senior nestlings received significantly more food and were significantly more aggressive than junior nestlings. Broods of three displayed significantly more aggression than broods of two, and aggression decreased significantly from week two to three. There was no significant relationship between the total amount of food consumed and the total amount of aggression in each nest, which rejects the food amount hypothesis.

The Effects Of Caffeine And Rapid Eye Movement (Rem) Sleep Deprivation On Free Operant Responding Under A Vi 30-S Schedule Of Reinforcement, Curtis Allen Bradley

Masters Theses, 2010-2019

Past research has shown that the effects of 96 hr of Rapid Eye Movement Sleep Deprivation (REMSD) on positively reinforced behavior is dependent upon the schedule of reinforcement maintaining the behavior. One one hand, lean schedules of reinforcement after REMSD maintained low rates of behavior. On the other hand, rich schedules of reinforcement after REMSD maintained behavior at baseline levels. Other research has shown that the use of stimulants reversed the effects of REMSD on operant tasks. The current study investigated the effects of caffeine on rats’ lever pressing after 96-hr REMSD. During baseline, doses of vehicle were administered 15 …

Supporting The Well Being Of University Student Survivors Of Cancer, Janice Lewis

Educational Specialist, 2009-2019

Young adult survivors of cancer present a unique set of needs and developmental factors to consider when working to support their well being (physical, mental, emotional, and social health). The experiences of these individuals can vary in many ways. This variety might include variables such as: age of diagnosis, type of cancer, type of treatment, resources available, family support, etc. The intent of this project is to examine and review the needs of young adult university student cancer survivors and address important considerations for professionals working to support their well being. Interviews with cancer survivors and a supportive professional were …

Fda And The Rise Of The Empowered Consumer, Lewis Grossman

Scholarly Articles in Law Reviews & Journals

This Article traces the still-evolving view of consumers of FDA-regulated products as capable, rational, and rights-bearing decision makers. It also examines the corresponding diminution of FDA’s role as a paternalistic gatekeeper collaborating with medical and scientific experts to prevent products and manufacturer-provided information from reaching the public. Compared with their 1960s counterparts, today’s consumers of food and drugs have far greater freedom to make unmediated choices among a wider variety of products, guided by a relative deluge of labeling and advertising information. Moreover, food and drug regulation, once the exclusive domain of bureaucrats and experts, has become a focus of …

Labor Issues During The Construction Of The Panama Canal, Paul C. Diebold

Young Historians Conference

The Panama Canal represented America’s first great achievement on the international stage. But in its triumph, the United States showed itself willing to pursue success on the backs of the laborers—most of them black—without whom the canal could not have become a reality. This paper focuses on these men—men who braved dangerous conditions and the institutionalized segregation of the Canal Zone despite America’s reluctance to confront the issue of racism over a group of non-citizen, non-white laborers hundreds of miles removed from any American city or shore.

Microbial Evaluation Of The Calamus Heated Gutta-Percha Delivery System, Christopher Smart Dds

Theses and Dissertations

If gutta-percha cartridges are contaminated with bacteria prior to obturation then contamination of the root canal system may result. Successful treatment not only depends on bacterial elimination but also depends on prevention of recontamination. This study was motivated by the observation that endodontists frequently use single use gutta-percha cartridges on multiple patients. The goal of this study was to determine if cross contamination occurred when a single gutta-percha cartridge in the Calamus™ Flow System was used on multiple patients. An effective recovery method was established during a pilot study using Enterococcus faecalis as a sample bacterium. Microbial recovery was obtained …

Phosphorylation Of Cdk9 At Ser175 Enhances Hiv Transcription And Is A Marker Of Activated P-Tefb In Cd4+ T Lymphocytes, Uri R. Mbonye, Giridharan Gokulrangan, Manish Datt, Curtis Dobrowolski, Maxwell Cooper, Mark R. Chance, Jonathan Karn

Faculty Scholarship

The HIV transactivator protein, Tat, enhances HIV transcription by recruiting P-TEFb from the inactive 7SK snRNP complex and directing it to proviral elongation complexes. To test the hypothesis that T-cell receptor (TCR) signaling induces critical post-translational modifications leading to enhanced interactions between P-TEFb and Tat, we employed affinity purification-tandem mass spectrometry to analyze P-TEFb. TCR or phorbal ester (PMA) signaling strongly induced phosphorylation of the CDK9 kinase at Ser175. Molecular modeling studies based on the Tat/P-TEFb X-ray structure suggested that pSer175 strengthens the intermolecular interactions between CDK9 and Tat. Mutations in Ser175 confirm that this residue could mediate critical interactions …

Reducing The Stigma Of Mental Illness Among Medical Students, Victoria Lawn, Matthew Jaffa, Catherine Babbitt-Cook, Burton Mark, Jane Dumsha, Marcus G. Bell, Denah M. Appelt

Research Day

Background: The American Osteopathic Association House of Delegates Resolution 205 recommends “increased awareness of depression amongst U.S. medical students” due to the increasing body of research describing the rise of depression, burn-out and suicide ideation among medical students. There is consequently a need to understand mental health issues as a component of professional development.

Hypothesis: A student-led symposium addressing mental and emotional health topics relevant to medical students will reduce the stigma associated with mental illness. Materials and

Methods: A 2-hour student-run “Patient Perspective” session was held during the second year neuroscience block in the PCOM DO program. One week …

Economic Evidence On The Effects Of The Indian Gaming Regulatory Act On Indians And Non-Indians, Katherine Spilde Ph.D., Jonathan B. Taylor

UNLV Gaming Research & Review Journal

When Congress passed the Indian Gaming Regulatory Act (IGRA) in 1988, some tribal leaders perceived the state compacting provision required for casino-style gaming on tribal lands as an erosion of tribal sovereignty that could undermine their early economic development successes and disrupt a precariously successful federal-tribal relationship with regard to tribal self-determination.

In hindsight, however, the substantial growth and myriad positive impacts of the first twenty years of tribal gaming under IGRA reveal the ways that the federal regulatory framework laid out in the law resolved numerous legal dilemmas that had plagued tribal gaming expansion. It is now clear that …

Providing More—And Better—Food By 2050, John W. Finley

Agricultural Research Magazine

The world in 2050 is predicted to have 9 billion people, who will differ in almost every way but one: They will all need to eat on a daily basis.

Their nutritional needs will be similar, too. Nutrition means eating, eating means food, and food means agriculture. Many people speak of the increased food needed for 9 billion, but in reality, the increased need is for nutrition. Thus, the world of 2050 will force a melding of two disciplines that have diverged in recent years—agriculture and nutrition.

We need to change our focus. We need sustainable nutrition as much as …

With the aid of high-tech tools, Agricultural Research Service and collaborating scientists are closing in on the genes in rice that regulate the uptake and storage of important minerals—a pursuit that could bolster the nutritional value of this cereal grain crop as a staple food for roughly half the world’s population.

Ultimately, the team envisions biofortifying rice using traditional plant breeding methods to develop new varieties whose kernels (grain) boast exceptionally high concentrations of essential minerals, including zinc, iron, and calcium.

Rice is a mainstay of the human diet for good reason. It is a rich source of energy, free …

Getting Hooked On Farmed Salmon: A Good Source Of Omega-3s, Susan Raatz, Matthew Picklo, William Wolters, Rosalie Marion Bliss

Agricultural Research Magazine

Nearly 85 percent of seafood enjoyed by U.S. consumers is imported, and almost half of that is farm raised through a process called “aquaculture,” according to the National Aquaculture Association, based in Pine Bluff, Arkansas. In 2011, the United States imported $16.6 billion of seafood and exported $5.4 billion, a difference of $11.2 billion.

As the world’s population grows and demand for seafood increases, many seafood species are overfished or fully exploited. That means the world’s oceans cannot turn out more fish than are currently being produced. As the ceiling is being reached on seafood availability from the wild, U.S. …
