The Development And Validation Of The Preference For Adherence To Theoretical Orientation Scale, Tiffinee S. Hamilton

Counseling & Human Services Theses & Dissertations

One of the most common criticisms of undergraduate and master's level graduate programs is that students lack the ability to define their view of human nature. One effective means of assisting students in their desire to identify their preference in orientation is the use of a validated psychometric instrument developed for mental health trainees. Thus, the purpose of this study is to develop and initially validate a new assessment tool, the Preference for Adherence to Theoretical Orientation Scale (PATOS). PATOS provides a theoretically grounded method for assessing a counselor's preference for a particular orientation(s) as well as adherence to a …

Factors That Influence Nonadherence Outpatient Medical Follow-Up By African Americans With Hiv/Aids At An Outpatient Infectious Disease Clinic, Cynthia Burrell Banks

Health Services Research Dissertations

Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) does not discriminate among different races, ethnicities or genders; however, African Americans carry a larger burden related to the HIV epidemic than others (CDC, 2010c; Cunningham, Sanchez, Heller & Sohler, 2007; Mugavero, et al., 2009). Persons living with HIV/AIDS (PLWHA) who do not adhere to their medical regimen, including failure to maintain contact with their health care provider for health care monitoring, tend to have poorer health outcomes from the disease as compared to HIV/AIDS patients who adhere to their medical regimen (Cunningham et al., 2006; Lima et al., 2009). African Americans represent …

The Influence Of Interlimb Differences On Anterior Cruciate Ligament Injury Risk Factors In Female Collegiate Soccer Athletes, Eric Kevin Greska

Human Movement Sciences & Special Education Theses & Dissertations

Female collegiate soccer athletes suffer anterior cruciate ligament (ACL) injuries at a rate of 0.31 per 1000 athlete-exposures, with 67% of injuries expected to be from a non-contact mechanism. As well, previous studies have demonstrated dissimilarity in non-contact ACL injuries relative to dominant and non-dominant legs; with the non-dominant leg being the involved side in 48-67% of reported incidents. The aim of this study was to examine lower extremity neuromechanics relative to leg dominance during an unanticipated sidestep cutting task, with differing states of fatigue and training.

Synergistic Effect Of Subnanosecond Pulsed Electric Fields And Temperature On The Viability Of Biological Cells, James Thomas Camp

Electrical & Computer Engineering Theses & Dissertations

Pulsed electric fields have been used to induce a biological response in cells, and at sufficient energy, can cause cell death. By reducing the pulse duration from presently used nanosecond to subnanosecond ranges, the electric field can be delivered to biological tissue non-invasively by the use of an antenna instead of electrodes, such as needles. Studies have previously been completed in which the aim was to determine the energy density (electric field strength, number of pulses) required to induce cell death with 800 ps pulses. Based on this data, it was concluded that for pulse durations of 200 ps, with …

Communication Disorders & Special Education Faculty Publications

Children with profound congenital hearing loss often do not have the same prelinguistic opportunities for social and verbal interaction as their peers with typical hearing [14]. Consequently, language and social skills may be challenging for this group, even after they are provided with amplification or a cochlear implant. This pilot study examined the effectiveness of using a parallel talk intervention to increase the language and interactional skills of three preschoolers with deafnesss. Results revealed that all participants increased verbal turn-taking and that two of the three increased initiated and responded vocal/verbal comments, and initiated and responded nonverbal responses during a …

Anthropogenic Climate Change And Allergic Diseases, James Blando, Leonard Bielory, Viann Nguyen, Rafael Diaz, Hueiwang Anna Jeng

Community & Environmental Health Faculty Publications

Climate change is expected to have an impact on various aspects of health, including mucosal areas involved in allergic inflammatory disorders that include asthma, allergic rhinitis, allergic conjunctivitis and anaphylaxis. The evidence that links climate change to the exacerbation and the development of allergic disease is increasing and appears to be linked to changes in pollen seasons (duration, onset and intensity) and changes in allergen content of plants and their pollen as it relates to increased sensitization, allergenicity and exacerbations of allergic airway disease. This has significant implications for air quality and for the global food supply.

Quality Of Life Of Families With Children Who Have Severe Developmental Disabilities: A Comparison Based On Child Residence, Joni Taylor Mcfelea, Sharon Raver

Communication Disorders & Special Education Faculty Publications

This study measured the quality of life of two groups of families with children who had severe developmental disabilities-families whose child lived at home and families whose child lived in a residential facility. Participants were 54 primary caregivers of children who had severe intellectual disabilities and who lacked the ability to both ambulate without assistance and communicate conversationally. Participants completed the "Family Quality of Life Scale" (Hoffman, Marquis, Poston, Summers, & Turnbull, 2006). Analyses revealed that both groups rated their family quality of life (FQOL) as exemplary. FQOL was higher in the family home group than in the residential facility …

In Vitro Antimicrobial Effect Of A Cold Plasma Jet Against Enterococcus Faecalis Biofilms, Chunqi Jiang, Christoph Schaudinn, David E. Jaramillo, Paul Webster, J. William Costerton

Bioelectrics Publications

The hypothesis that a cold plasma jet has the antimicrobial effect against Enterococcus faecalis biofilms was tested in vitro. 27 hydroxyapatite discs were incubated with E. faecalis for six days to form a monoculture biofilm on the disc surface. The prepared substrata were divided into three groups: the negative control, the positive control (5.25% NaOCl solution), and the plasma treatment group. Resultant colony-forming unit counts were associated with observations of bacterial cell morphology changes using scanning electron microscopy (SEM). Treatment of E. faecalis biofilm with the plasma and 5.25% NaOCl for 5min resulted in 93.1% and 90.0% kill (P < 0.0001), respectively. SEM detected that nearly no intact bacteria were discernible for the plasmaexposed HA disc surfaces. The demonstrated bactericidal effect of the plasma with direct surface contact may be due to the enhanced oxidation by the locally produced reactive plasma species.

Advancing Our Understanding Of The Inheritance And Transmission Of Pectus Excavatum, Lisa Horth, Michael W. Stacey, Virginia K. Proud, Kara Segna, Chelsea Rutherford, Donald Nuss, Robert E. Kelly

Bioelectrics Publications

Pectus excavatum is the most common congenital chest wall abnormality expressed in children, yet its inheritance is poorly understood. Here we present the first comprehensive assessment of the inheritance of this disorder. After evaluating 48 pedigrees and 56 clinical traits of probands and family members, we find strong evidence of autosomal recessive, genetic control for this disorder. Additionally there is likely more than one pectus disease-associated allele, as well as a relatively large number of disease allele carriers in the human population. Some clinical traits appear important and may serve as reliable indicators for predicting the likelihood of pectus excavatum …
