Feed Comparison For Dietary Standardization Of The Sea Urchin Lytechinus Variegatus And Assessment Of Parental Dietary Copper Toxicity By Fertilization And Embryological Tests, Heath W. Garris

All ETDs from UAB

Toxicity tests monitoring the effects of anthropogenic substances on marine systems are considered an important part of environmental management. Sea urchin fertilization and embryological toxicity tests are successful in producing a graded response to toxicants, but standards for controlling the quality of parental urchins have not been developed. In Chapter 1, experimental populations of Lytechinus variegatus were fed either organic romaine lettuce and organic carrots, or a feed formulated for sea urchins for 13 weeks. Growth demographics were assessed and F1 progeny were compared for sensitivity to the toxicants copper sulfate, 1,3,5-trinitrobenzene, and sodium dodecyl sulfate by acute embryonic and …

A Descriptive Overview Of The Jefferson County Mental Health Court, Crystal Rena Null

All ETDs from UAB

Mental health courts have been established to help meet the treatment needs of the mentally ill offender. If mentally ill offenders commit crimes because of their mental illness, then “by treating [them], society may benefit through reduced recidivism and improvements in social outcomes” (Mears, 2004, 258). This study focuses on the Jefferson County Mental Health Court and its participants. It addresses two main research questions: 1) Who participants in the Jefferson County Mental Health Court; and 2) What factors exist to help predict who successfully completes the Jefferson County Mental Health Court? Unlike the majority of other mental health courts, …

A Rhetoric Of Resolution: The Limits Of Competition, Michael Schandorf Jan 2008

A Rhetoric Of Resolution: The Limits Of Competition, Michael Schandorf

All ETDs from UAB

The idea of competition underlies most all Western cultural practices making conflict inevitable, but understanding the world in terms of constant, perpetual competition limits the development of lasting, adaptive, and constructive solutions to human problems and conflicts. While competition serves the vital functions of quality control and the identification of best practices, the function of “Competition” as a god term betrays a misunderstanding of both the value and process of competition as an instrument, and demonstrates how human conceptualization, mediated by language, can direct the development and acquisition of knowledge into narrow channels and exclude ways of understanding that are …

A Simple Plan, A Simple Faith: Chaplain And Local Congregant Strategies For Sharing Faith In The Prison Context, Jessica P. Shoemaker Jan 2008

A Simple Plan, A Simple Faith: Chaplain And Local Congregant Strategies For Sharing Faith In The Prison Context, Jessica P. Shoemaker

All ETDs from UAB

As the prison population in the United States continues to expand, so too has the use of faith-based prison programs as tools for correctional treatment. Using in-depth interviews with thirty current prison chaplains and local religious congregants in Mississippi, I explore the strategies and techniques used by prison ministry workers in their work with inmates. Two overarching themes emerged from the narratives of prison ministry work. The first is that the ministry workers were careful to avoid setting or focusing on numeric goals for religious conversions before interacting with the inmates. They reported that this approach was based on their …

Traffic Responsive Signal Systems To Address Rain-Related Congestion, Suman Reddy Surabhi Jan 2008

Traffic Responsive Signal Systems To Address Rain-Related Congestion, Suman Reddy Surabhi

All ETDs from UAB

Rainy conditions typically have an impact on the behavior of drivers and in turn can affect traffic flow characteristics in transportation networks. As a result, signal timing plans developed for dry conditions may be unsuitable or sub-optimal during periods of rain, and changes in such plans may be desirable to account for changes in environmental conditions. Current technology in the field of traffic signal control and communications make it possible to change the signal controller settings remotely, a capability that offers opportunities for signal timing adjustments during rain conditions. This study explores the feasibility and benefits of implementing alternative signal-timing …

Regulation Of Tau Functions By Posttranslational Modifications Of Tau And Histone Deacetylase 6, Huiping Ding Jan 2008

Regulation Of Tau Functions By Posttranslational Modifications Of Tau And Histone Deacetylase 6, Huiping Ding

All ETDs from UAB

Alzheimer’s disease (AD), the most common neurodegenerative disease, is pathologically characterized by senile plaques composed of amyloid β peptide and neurofibrillary tangles composed of hyperphosphorylated and aberrantly cleaved microtubule-associated protein tau. Numerous studies have demonstrated the critical importance of tau in AD pathogenesis; however, the mechanisms involved in the regulation of tau functions by posttranslational modifications of tau and by other cellular factors need to be further elucidated. The first part of my study focused on how posttranslational modifications of tau, specifically, site-specific phosphorylation and C-terminal cleavage, regulate its physiological function in associating with cytoskeleton, binding to and stabilizing microtubules …

High Field Functional Magnetic Resonance Imaging In The Awake, Behaving Primate: Cortical Networks Involved In Vergence Eye Movements, Matthew K. Ward Jan 2008

High Field Functional Magnetic Resonance Imaging In The Awake, Behaving Primate: Cortical Networks Involved In Vergence Eye Movements, Matthew K. Ward

All ETDs from UAB

Animals with eyes positioned towards the front of the head are capable of making saccadic and smooth pursuit eye movements to fixate an object at a given distance. These eye movements are conjugate (i.e. both eyes move the same amount in the same direction). To fixate objects at different distances, such animals are also capable of making vergence eye movements in which both eyes move the same amount in opposite directions i.e. disconjugately. While purely conjugate or vergence eye movements rarely occur in daily life, it is useful to study these types of eye movements separately due to the relative …

A Macro-Bend Fiber Based Wavelength Demodulation System For Optical Fiber Sensing Applications, Ginu Rajan Jan 2008

A Macro-Bend Fiber Based Wavelength Demodulation System For Optical Fiber Sensing Applications, Ginu Rajan

Doctoral

This thesis considers the design and development of a wide range all fiber interrogation system with a rapid measurement capability for extracting reliable measure and information from fiber Bragg grating sensors. Existing passive and active interrogation systems have certain limitations and do not satisfy all requirements. In this thesis a wavelength demodulation system is proposed, based on a macro-bend fiber filter employed in a ratiometric detection scheme. A theoretical model and analysis of an edge filter based ratiometric wavelength measurement (RWM) system is presented. A fiber edge filter is realized by carefully selecting an appropriate bend radius and number of …

Investigation Of The Electronic Properties Of Organic Systems Using Electroabsorption Spectroscopy, Garrett F. Farrell Jan 2008

Investigation Of The Electronic Properties Of Organic Systems Using Electroabsorption Spectroscopy, Garrett F. Farrell

Doctoral

The aim of this project is to investigate the effect of bulk structural modification on the electronic properties of fullerene systems as measured using electronic and Electroabsorption (EA) spectroscopy. The existence of a unique solid state feature in C60 is the first indication that the material’s electronic properties may be influenced by its crystalline environment and as such merits investigation. The nature and extent of these interactions in the solid state is still unclear, in particular whether the molecular electrons remain located on the individual molecules or whether they are delocalised across the solid. The extent of these interactions has …

Student -Teacher Relationships And Their Effect On Student Achievement At The Secondary Level, Cheryl Dix Modlin Jan 2008

Student -Teacher Relationships And Their Effect On Student Achievement At The Secondary Level, Cheryl Dix Modlin

Walden Dissertations and Doctoral Studies

Previous research has demonstrated that adolescent learning increases with a proactive type of student-teacher relationship. However, due to the lack of common expectations for a positive student-teacher relationship, a disconnection occurs for some students, who then may become disengaged at school and may not reach their full potential academically, socially, or developmentally. This mixed method sequential, exploratory design focused on a Midwestern secondary school of approximately 250 students. The disconnection between students and teachers was addressed by investigating positive student-teacher relationships; student achievement; and the connection between student-teacher relationships and achievement. Qualitative data were collected using focus groups of students …

Parental Payment Abuse Within The Supplemental Security Income Program, Darlean Taylor-King Jan 2008

Parental Payment Abuse Within The Supplemental Security Income Program, Darlean Taylor-King

Walden Dissertations and Doctoral Studies

Management of Social Security Administration (SSA) has been challenged by the phenomena of overpayments with its Supplemental Security Income (SSI) program. Oversight authorities of SSA had expressed concerns about the overpayment abuse caused by parents as representative payees for disabled minor children. It was important to address this problem because the amount of overpayments prior to 1998 had caused integrity issues for management of SSA and increased federal debt from SSI claimants. The purpose of this study was to examine how management of SSA and the SSI program had responded to the concerns of the oversight authorities. Theoretical foundations for …
