Discrimination Of Duration Differences Of Typically Developing Children And Children With Suspected Childhood Apraxia Of Speech, Susan B. Ingram Dec 2014

Discrimination Of Duration Differences Of Typically Developing Children And Children With Suspected Childhood Apraxia Of Speech, Susan B. Ingram

Dissertations, 2014-2019

The speech sound disorder, childhood apraxia of speech (CAS), has perplexed clinicians and researchers for many years. The perplexity has stemmed, in part, from questions about identifying characteristics that distinguish it from other childhood speech disorders. Given the reported vowel duration deficits cited in the speech production of children with sCAS, the research for this population is deficient in assessing the ability of these children to discriminate vowel duration differences. The present study represents an initial attempt to address duration discrimination in a systematized experimental design for a group of school-age TD children (n = 21) and a smaller group …


Comparison: Perception And Knowledge Of Protein Consumption In Female Athletes For Post Weight Lifting Recovery, Samantha Jane Lofton Dec 2014

Comparison: Perception And Knowledge Of Protein Consumption In Female Athletes For Post Weight Lifting Recovery, Samantha Jane Lofton

Senior Honors Projects, 2010-2019

A study was conducted on James Madison University’s campus to assess the knowledge, beliefs, perceptions and habits of protein consumption post resistance training in female student athletes. Sixty-two female athletes who regularly partake in resistance training filled out a recovery-cue questionnaire containing 10 statements/questions on the subject of protein consumption. The data was analyzed using IBM SPSS, Version 21.0 and Microsoft Office Excel. Eight percent of respondents stated they are aware of how much protein they should be consuming post workout, and 21% feel what they consume post workout is an adequate amount of protein for muscle recovery. Forty-six percent …


Profile Of The Unfolded Protein Response In C. Elegans Depleted Of The Translational Chaperone, Nac., Caylin S. Murray Dec 2014

Profile Of The Unfolded Protein Response In C. Elegans Depleted Of The Translational Chaperone, Nac., Caylin S. Murray

Masters Theses, 2010-2019

The function of a protein is a direct consequence of its final structure, which is achieved by protein-folding processes that generate a tertiary state through the juxtaposition of locally formed secondary structures. Because all cells need functional proteins to survive, each contains robust and redundant mechanisms that regulate the folding of newly forming proteins, and the refolding of misfolded proteins that are often generated during stress. Essential to these mechanisms, chaperones are proteins that aid in protein folding of nascent and misfolding protein without being incorporated in the final structure. One chaperone complex, the nascent polypeptide-associated complex (NAC), aids in …


Colloidal And Biological Properties Of Triscationic Amphiphiles With One Or Two Tails, John N. Marafino Dec 2014

Colloidal And Biological Properties Of Triscationic Amphiphiles With One Or Two Tails, John N. Marafino

Masters Theses, 2010-2019

The decline in the development of novel antimicrobials, combined with the misusage and over prescription of antibiotics, has contributed to the increasing prevalence of antimicrobial-resistant infections. Thus development of effective novel disinfectants could reduce the transmission of pathogens and decrease the risk of infection by antibiotic resistant organisms. The antimicrobial activity of amphiphiles, compounds with hydrophobic and hydrophilic regions, was first reported in 1935, and has influenced the synthesis of amphiphiles with variations in structure. In this study, three series of amphiphiles were synthesized by two subsequent Menshutkin reactions. Each amphiphile contains one or two hydrocarbon tails ranging from 8 …


A Study Into The Diagnosis Of Obesity In Infants Less Than Two Years Old In The State Of Virginia, Lindsay Ann Bruno Dec 2014

A Study Into The Diagnosis Of Obesity In Infants Less Than Two Years Old In The State Of Virginia, Lindsay Ann Bruno

Senior Honors Projects, 2010-2019

In 2007, the CDC reported approximately 12.5 million children and adolescents in the U.S. were obese. Among 24-month old clinically obese children, only 23% were diagnosed as obese. The most concerning is the prevalence of obesity in 6-month olds; 16% of 6-month old infants in the U.S. are obese, of which only 14% are diagnosed as being obese. Previous research concentrates on the factors that influence infant obesity, but does not address the prevalence of diagnosing obesity in children, particularly those under two years of age. The purpose of this project was to pioneer a survey exploring the prevalence of …

Effects Of Running Sprint Interval Training Versus Traditional Endurance Exercise On Metabolic Indices In Sedentary, Overweight And Obese Women, Jennifer Lynn Espinoza May 2014

Effects Of Running Sprint Interval Training Versus Traditional Endurance Exercise On Metabolic Indices In Sedentary, Overweight And Obese Women, Jennifer Lynn Espinoza

Masters Theses, 2010-2019

Evidence suggests that sprint interval training (SIT) is a time efficient alternative for improving aerobic fitness or insulin sensitivity due to its reduced training volume and is of increasing interest since most sedentary individuals indicate lack of time as their number one barrier to being physically active. However, most SIT research uses cycling exercise performed with healthy active males, and limited research examines its effects on women or individuals at higher risk for inactivity related diseases, as well as different modes of exercise. PURPOSE: To evaluate the effects of running SIT (R-SIT) versus moderate intensity endurance training (MIET) on aerobic …


Effects Of Auditory And Visual Distracters On Acceptable Background Noise Level In Hearing-Impaired Listeners, Elizabeth A. Ripley May 2014

Effects Of Auditory And Visual Distracters On Acceptable Background Noise Level In Hearing-Impaired Listeners, Elizabeth A. Ripley

Dissertations, 2014-2019

Acceptable Noise Level (ANL), is an established procedure for determining the amount of background noise a listener is willing to accept while listening to speech. ANL is established by having the listener select most amount of background noise they are willing to accept while listening to a speech stimulus presented at their most comfortable listening level (MCL). While ANLs have been established as good predictors of hearing aid use, little is known on how hearing aid users accept background noise while engaged in cognitively demanding tasks. Previous research in normal hearing listeners has demonstrated that listeners will allow the most …


The Neural Representation And Behavioral Detection Of Frequency Modulation, Daniel Elliott Shearer May 2014

The Neural Representation And Behavioral Detection Of Frequency Modulation, Daniel Elliott Shearer

Dissertations, 2014-2019

Understanding a speech signal is reliant on the ability of the auditory system to accurately encode rapidly changing spectral and temporal cues over time. Evidence from behavioral studies in humans suggests that relatively poor temporal fine structure (TFS) encoding ability is correlated with poorer performance on speech understanding tasks in quiet and in noise. Electroencephalography, including measurement of the frequency-following response, has been used to assess the human central auditory nervous system’s ability to encode temporal patterns in steady-state and dynamic tonal stimuli and short syllables. To date, the FFR has been used to investigate the accuracy of phase-locked auditory …


Effects Of Eph/Ephrin Mutations On Pre Pulse Inhibition In Mice, Andrea Marie Liuzzo May 2014

Effects Of Eph/Ephrin Mutations On Pre Pulse Inhibition In Mice, Andrea Marie Liuzzo

Dissertations, 2014-2019

The acoustic startle response (ASR) is a reliable reflexive behavioral response in mammals elicited by an unexpected intense acoustic startle eliciting stimulus (SES). It is mediated by a sub-cortical pathway that includes the inferior colliculus (IC). The ASR amplitude can be measured with an accelerometer beneath the subject attached to the cage, and can be decreased in amplitude by presenting a less intense, non-startling stimulus 20-300 ms before the SES. This reflexive decrement in ASR is called pre pulse inhibition (PPI) and indicates that the relatively soft pre pulse was heard. Murine species have been used to study this response …


Community-Campus Partnership Effectiveness For Nursing Faculty Curricula In Rural Virginia, Adriana Myers Jan 2014

Community-Campus Partnership Effectiveness For Nursing Faculty Curricula In Rural Virginia, Adriana Myers

VA Engage Journal

Nursing schools state that faculty shortages caused by low faculty salaries are a primary reason for nursing shortages. In a Shenandoah University graduate survey, many nurses wanted to teach but could not leave their higher-paying clinical jobs. Shenandoah University’s Graduate Program in Winchester, VA received funding from the Virginia Health Workforce Development Authority to use rural community-campus partnerships to plan a nursing faculty residency program to increase the number of nursing faculty. The program’s planning partners were economic development, business, academic, and philanthropic organization leaders in seven rural planning districts. Community Based Participatory Research was used to assess the effectiveness …


Helping The Community From The Bottom Up: Distributing Diapers To The Williamsburg Community, Constance A. Hull, Caroline Kelsey Jan 2014

Helping The Community From The Bottom Up: Distributing Diapers To The Williamsburg Community, Constance A. Hull, Caroline Kelsey

VA Engage Journal

There is a great need for a sustainable supply of clean diapers for low-income residents of Williamsburg since this region is without a diaper bank. Being unable to afford diapers can have a myriad of negative consequences from being unable to send children to child care to increased health risks involved in leaving a baby in a soiled diaper. Our model of a diaper bank differs from most because we mail diapers directly to families, eliminating transportation needs. We hope to partner with community agencies and The College of William & Mary to expand our services and create a more …
