Growth And Characterization Of Zno For The Front Contact Of Cu(In,Ga)Se2, Rita Bhatt

USF Tampa Graduate Theses and Dissertations

ZnO window layers for CIGS solar cells are grown with a DC sputtering technique instead of a conventional RF sputtering technique. Transparent window layers and buffer layers are sputtered from the Zn target in the presence of Oxygen. The window layer is doped with Aluminum in order to achieve high electrical conductivity and thermal stability. The effect of different sputtering parameters on the electrical and optical properties of the films is elaborately studied. Sets of annealing experiments are also performed. Combinations of different deposition parameters are examined to design the optimum fabrication conditions. We are able to deposit 85% transparent, …

Evaluation And Treatment Of Tinnitus, Renee Lokenberg

USF Tampa Graduate Theses and Dissertations

Tinnitus is defined as an auditory stimulus that is unrelated to external stimulation. There are many theories as to what causes tinnitus, therefore, there are many treatment options for tinnitus. This paper attempts to increase the audiologist's knowledge of the etiology, as well as, the most appropriate treatment for tinnitus.

There are two types of tinnitus, objective and subjective. Subjective tinnitus is more common, although it is more difficult to treat than objective tinnitus. There are many theories as to what causes tinnitus. Several disorders that have tinnitus as a symptom, such as, Meniere's disease, acoustic neuroma, and dysfunction of …

Survey Of Auditory Brainstem Response Referral Criteria, Shannon N. Felder

USF Tampa Graduate Theses and Dissertations

The primary objective of the project was to survey recognized “experts” in the field of neurodiagnostic audiology and practicing audiologists regarding their referral criteria and referral patterns for administering an auditory brainstem response test (ABR). For purposes of this study, “expert” was defined as any recognized audiologist with at least two or more publications and/or seminars in the field of auditory evoked potentials. Responses of experts and practicing audiologists were compared and contrasted to establish: a) if there was a standard referral pattern; b) what, if any, were the apparent critical components of referral patterns; and, c) whether or not …

Difference In Hearing Screening Failure Rates As A Function Of Ethnicity In Well Newborns Screened At Tampa General Hospital, Sybil N. Prewitt

USF Tampa Graduate Theses and Dissertations

The difference in otoacoustic emission (OAE) hearing screening failure rates as a function of ethnic category was investigated in a population of newborns at Tampa General Hospital, Tampa, Florida. Clinical observation led to a concern that due to a higher incidence of outer and middle ear dysfunction in Hispanic newborns and children, screening could result in disparate failure rates, with a larger number of these infants requiring further testing. This result would warrant changes in current protocols, as well as screener training,and parent counseling practices.

Between January and July of 2000, 1407 newborns were tested utilizing distortion product otoacoustic emission …

Incidence Of Unilateral, High Frequency, Sensorineural Hearing Loss In Shunt Treated Hydrocephalic Children Ipsilateral To Shunt Placement, Susan E. Spirakis

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate further the characteristics of hearing loss in ventriculoperitoneal (VP) shunted hydrocephalus. Twelve (VP) shunt treated hydrocephalus children participated in this study. The etiology of the hydrocephalus was either intraventricular hemorrhage or spina bifida. A recent neurological examination reported the shunt to be patent in each child. Audiometric examination included pure tone air conduction thresholds, tympanometry, contralateral and ipsilateral acoustic reflex thresholds and distortion product otoacoustic emissions (DPOAEʹs). A unilateral, high frequency, sensorineural hearing loss was found in the ear ipsilateral to shunt placement in 10 (83%) of the 12 shunt treated hydrocephalic …

The Role Of Audiology Technicians In The Va System, John Terry Berardino

USF Tampa Graduate Theses and Dissertations

Eligibility reform in the VA and the resulting increased caseloads have brought about unacceptable wait times for new audiology appointments. Mandates to decrease wait times without increased resources have brought new demands on audiology clinics. One proposed solution is the addition of audiology technicians to VA audiology clinic practice.

The first purpose of this study was to survey the attitudes of VA audiologists and service chiefs regarding the use of technicians. The second purpose was to ask the survey respondents to assign as generally appropriate or inappropriate, job duties which might be accomplished by an audiology technician. Following a pre-survey …

Women, Environment And Development: Sub-Saharan Africa And Latin America, Evaline Tiondi

USF Tampa Graduate Theses and Dissertations

Issues related to women, environment and development constitute a major global concern today. Women's roles as agents of change in the environment has increasingly become the focus of both research and policy concerns. Environmental resource management is directly linked to development, and this makes it crucial to examine the activities of women more closely. Women's role in the management of natural resources assumes a multidimensional nature. Unfortunately, the central and crucial role that women play is often both overlooked and unappreciated, rendering them invisible and greatly diminishing their contribution as both producers and active agents in sustainable development. One of …

Use Of The Client Oriented Scale Of Improvement As A Clinical Outcome Measure In The Veterans Affairs National Hearing Aid Program, Robert F. Zelski

USF Tampa Graduate Theses and Dissertations

In the present health care environment, there is an increased demand for audiologists to measure the outcomes of hearing aid intervention. In addition to the more traditional objective outcome measures, many subjective outcome measures have been developed in the last 20 years. Two such subjective outcome measures are the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Hearing Handicap Inventory for the Elderly (HHIE). These instruments consist of a series of pre-selected questions that may or may not be applicable to an individual. An alternative to the pre-selected question format is an open format design that allows the person …
