Cognitive Training Refines Connectivity Of The Aging Human Brain To Improve Performance, Christine R. Denning Jan 2013

Cognitive Training Refines Connectivity Of The Aging Human Brain To Improve Performance, Christine R. Denning

All ETDs from UAB

Cognitive deficits that occur as a function of age are highly variable within a sample of older adults of similar age. Training paradigms are available that can reverse cognitive declines that occur with age and improve behavioral performance. However, the benefits of training are also highly variable. The goal of this study was to use func-tional connectivity analyses on functional MRI data to help identify the source of this variability and to determine if cognitive training could alter network structure in the ag-ing human brain. Resting-state functional connectivity data was acquired to investigate several neural networks in forty-one older adults. …

Modulation Of Intrinsic Activity In Sensory Cortex Facilitates Task Performance, Aburahman Elkhetali Jan 2013

Modulation Of Intrinsic Activity In Sensory Cortex Facilitates Task Performance, Aburahman Elkhetali

All ETDs from UAB

Due to the changing demands of the environment and our behavioral intentions the brain has to adapt in order to produce task appropriate responses. Part of the challenge is the large amount of sensory information received by the brain. Depending on individu-al goals, the brain must select and react to task appropriate stimuli while ignoring other irrelevant sensory input. Since behavioral intentions are dynamic, this requires the re-sponses within the brain to also be dynamic. Cognitive control, exerted by higher centers on sensory cortex allow for selection of task relevant stimuli. In this study we find that intrinsic, non-stimulus driven …

Adap1 And Arf6 Mediate Regulated Secretory Trafficing In Neurosecretory Cells And Neurons, Sharday Ewell Jan 2013

Adap1 And Arf6 Mediate Regulated Secretory Trafficing In Neurosecretory Cells And Neurons, Sharday Ewell

All ETDs from UAB

ADP ribosylation factor 6 (Arf6) is a member of the Arf family of small GTPases known to function in vesicular membrane trafficking and cytoskeletal organization. Arf6 cycles between its GTP and GDP bound states, facilitated by GTP exchange factors (GEFs) and GTPase activating proteins (GAPs), respectively. In my dissertation studies I have investigated the neuronal functions of Arf6 and ADAP1, an Arf6 GAP and candidate PI 3-kinase target required for dendritic differentiation in developing neurons. I demonstrated that in neurosecretory PC12 cells and neurons, ADAP1 and Arf6 colocalize with regulated secretory granules (SGs) that traffic chromogranin B and brain-derived neurotrophic …

Photothermal Desorption Of Toluene From Single Walled Carbon Nanotube And Activated Carbon Sorbents, Evan Lee Floyd Jan 2013

Photothermal Desorption Of Toluene From Single Walled Carbon Nanotube And Activated Carbon Sorbents, Evan Lee Floyd

All ETDs from UAB

Millions of workers are occupationally exposed to volatile organic compounds (VOC) annually, requiring exposure assessments through air sampling. Reducing time to knowledge while maintaining adequate sensitivity and affordability is a constant struggle. Sorbent sampling is the preferred technique for VOC exposure assessments. Chemical desorption of sorbents is the most common desorption technique, but sensitivity is limited due to the small injection fraction. Thermal desorption has excellent sensitivity, but provides only one analysis per sample and is cost prohibitive. The goal of this dissertation was to develop a desorption technique that bridges the sensitivity gap between chemical desorption (0.1%) and thermal …

Host Genetic Factors Associated With Cervical Human Papillomavirus Clearance, Staci Lynn Sudenga Jan 2013

Host Genetic Factors Associated With Cervical Human Papillomavirus Clearance, Staci Lynn Sudenga

All ETDs from UAB

This dissertation research focuses on how variants in various host genes are associated with clearance of HPV in three longitudinal cohorts from the United States. I first examined the definition of the intermediate phenotype to cervical cancer, HPV persistence and then I incorporated this phenotype in all my three aims by examining variations in xenobiotic metabolism genes in HIV-1 negative and immune-related genes in HIV-1 positive females and how these contribute to HPV infection outcomes. Several significant variants were associated with HPV clearance for the three aims. For the first aim, in ALTS assessing functional variants within xenobiotic metabolism genes …

Lightweight Data Location Services For Exascale Storage Systems, Zhiwei Sun Jan 2013

Lightweight Data Location Services For Exascale Storage Systems, Zhiwei Sun

All ETDs from UAB

In order to satisfy the storage demands of Exascale computing by 2018 (a stated goal of the US government and the HPC research community), a number of Exascale storage systems have begun to be designed and explored to facilitate application checkpointing and parallel file storage. Nondeterministic storage systems (which weaken the assumptions of Terascale and Petascale predecessors) can provide useful capabilities that are difficult to implement in today's parallel file systems, such as high-performance writes, dynamic load-balancing, enriched flexibility of moving data and creating replicas, and potentially other features. However, locating data and reading data back from nondeterministic storage systems …

Influence Of Implant Angulation On The Fracture Resistance Of Zirconia Abutments, Shreedevi Thulasidas Jan 2013

Influence Of Implant Angulation On The Fracture Resistance Of Zirconia Abutments, Shreedevi Thulasidas

All ETDs from UAB

Zirconia-based implant abutments are widely used in prosthetic dentistry. Custom made abutments are utilized to correct for non-ideal implant positions and can successfully accommodate the morphologic requirements of the overlying crown. It was hypothesized that there will be difference in fracture strength and fracture mode of artificially aged zirconia implant abutments supported by implants at varying angulation, when load is applied to failure on overlying zirconia crowns. The implant-abutment-crown assemblies were subjected to steam autoclaving to induce some degree of phase transformation from tetragonal to weaker monoclinic form and to thermo-cycling to artificially age the samples. The effects of loading …

Role Of Kca3.1, A Calcium-Activated Potassium Channel, In Cell Migration In The Adult Brain, Kathryn L. Turner Jan 2013

Role Of Kca3.1, A Calcium-Activated Potassium Channel, In Cell Migration In The Adult Brain, Kathryn L. Turner

All ETDs from UAB

A limited amount of migration occurs in the adult brain, including migration of neuroblasts during adult neurogenesis and pathological migration of primary brain tumors. Ion channels are commonly utilized during migration to allow shape and volume changes required for cell movement, and we specifically examine the role of KCa3.1 in the adult brain. These channels are well-suited to facilitate movement because they respond to common migration signals, i.e. intracellular Ca2+ changes, and efflux K+, allowing the outflow of water and cell volume regulation. Our findings suggest that KCa3.1 is highly expressed in migratory cells, adult neuroblasts and glioma cells, but …

Amatory Conventions, Luxury Trade, And The Culture Of Excess In The Rape Of The Lock, Roxana, And Gulliver's Travels, David Glennon Vinson Jan 2013

Amatory Conventions, Luxury Trade, And The Culture Of Excess In The Rape Of The Lock, Roxana, And Gulliver's Travels, David Glennon Vinson

All ETDs from UAB

This thesis expands scholarship in the study of amatory fiction by introducing three male canonical authors--Pope, Defoe, and Swift--into a body of criticism typically focused on female non-canonical authors. The authors' awareness and engagement of the amatory template calls for a reconsideration of the profound role in which the amatory genre plays in the novel tradition. I examine how amatory tropes are used in The Rape of the Lock, Roxana, and Gulliver's Travels to satirize sexual politics in the domestic sphere, but I also extend amatory studies by positioning the authors' satire in the public setting of a changing Britain. …

Electric Field Standing Wave Effects In Ft-Ir Transflection Spectra Of Biological Tissue Sections: Simulated Models Of Experimental Variability, Tomasz P. Wrobel, Barbara Wajnchold, Hugh Byrne, Malgorzata Baranska Jan 2013

Electric Field Standing Wave Effects In Ft-Ir Transflection Spectra Of Biological Tissue Sections: Simulated Models Of Experimental Variability, Tomasz P. Wrobel, Barbara Wajnchold, Hugh Byrne, Malgorzata Baranska

Articles

The so-called electric field standing wave effect (EFSW) has recently been demonstrated to significantly distort FT-IR spectra acquired in a transflection mode, both experimentally and in simulated models, bringing into question the appropriateness of the technique for sample characterization, particularly in the field of spectroscopy of biological materials. The predicted effects are most notable in the regime where the sample thickness is comparable to the source wavelength. In this work, the model is extended to sample thicknesses more representative of biological tissue sections and to include typical experimental factors which are demonstrated to reduce the predicted effects. These include integration …

‘An Isle Full Of Noises’: The Perception & Influence Of Sound In Shakespeare’S The Tempest, Paul A. Di Salvo Jan 2013

‘An Isle Full Of Noises’: The Perception & Influence Of Sound In Shakespeare’S The Tempest, Paul A. Di Salvo

Student Publications

Since the play’s authorship in 1610, actor-managers and directors alike have struggled over staging the opening scene of William Shakespeare’s The Tempest. The physical presence of the ship, the sounds and lighting effects of thunder and lightning, the dialogue of the actors, and the use of music have varied from the early 17th century to the present in an effort to appeal to the audience. The presentation of these elements, especially sound cues and music, prepares audiences to understand the dynamics of Prospero’s powers and transformation as a character. Depending on how sound and stage technologies were implemented …

She's A Brick House: August Wilson And The Stereotypes Of Black Womanhood, Amelia Tatum Grabowski Jan 2013

She's A Brick House: August Wilson And The Stereotypes Of Black Womanhood, Amelia Tatum Grabowski

Student Publications

In his Century Cycle of plays, August Wilson tells ten distinct stories of families in or linked to the Hill District, an African American community in Pittsburgh; one play taking place in each decade of the twentieth century. Through these plays, Wilson's audience sees the Hill District and America evolve, while prejudice, oppression, and poverty remain constant. Many scholars argue that sexism provides a fourth common factor, asserting that Wilson portrays the female characters in the male-fantasized, stereotypical roles of the Mammy or the Jezebel figure, rather as realistic, empowered, and complex women. However, close examination of the women with …

The Flow Of The Social: Developing A Constructal Systemic Approach To The Study Of Health Inequalities, William A. Anderson Jan 2013

The Flow Of The Social: Developing A Constructal Systemic Approach To The Study Of Health Inequalities, William A. Anderson

All ETDs from UAB

Society is a dynamic, living system. People, groups, institutions, and cultures are intricately interconnected. Changes in one area of society create changes in other areas. Causes and results may be closely linked or separated by time and space. Sociologists readily acknowledge this dynamic reality. However, our mainstream theories and methods often fail to account for it. Even after decades of research into social inequalities in health, medical sociology still seems far away from being able to offer any definitive ideas about why such inequalities exist and persist despite efforts to alleviate them. Medical sociology (and sociology in general) is centered …

Texas Annual Survey: Securities Regulation, George Lee Flint Jr Jan 2013

Texas Annual Survey: Securities Regulation, George Lee Flint Jr

Faculty Articles

The Fifth Circuit’s determination of a passive investor’s equity interest in a limited liability company as “securities” brings this class of investors under the protection of the Texas Securities Act (“TSA”). The TSA recognizes vicarious liability theories of aiding and abetting liability and control person liability, which hold secondary parties accountable for their actions. During the Survey period, several cases found secondary parties with positions of control or who met the elements of common law fraud culpable. In Fernea v. Merrill Lynch Pierce Fenner & Smith, Inc., the court found that a business could be liable for an employee’s actions …

Opportunistic Trademarking Of Slogans: It’S No Clown Issue, Bro, Lee B. Burgunder

Cardozo Arts & Entertainment Law Journal

In June 2012, Bryce Harper, the Rookie of the Year ballplayer for the Washington Nationals, responded to a reporter's inquiry with the statement, "That's a clown question, bro." The humorous retort was aired widely in the media, and gained such popularity that even Senate Majority Leader Harry Reid used it at a press conference. The day after Harper made the statement, he filed an intent-to-use trademark application for the slogan on t-shirts, hats and other types of products typically used by owners to express their personalities (herein called "billboard products"), and the United States Patent and Trademark Office ("PTO") quickly …

The Effect Of Surface Indications On The Tensile Properties Of Cast Steel, Jeff Hamby Jan 2013

The Effect Of Surface Indications On The Tensile Properties Of Cast Steel, Jeff Hamby

All ETDs from UAB

The objective of this thesis was to study the effect of surface indications on the tensile properties of cast steel. Four cast steel grades were selected for evaluation; these grades include three carbon and low alloy steels (110/80, 165/135, and Eglin) and one high alloy steel (CF8M). Using these steels, tensile specimens were produced, inspected via MT/PT, categorized by surface indications (as-cast or machined), and tested. Bars with natural surface indications were tensile tested and the properties recorded. The presence of a 1/16 inch, 1/8 inch, or 1/4 inch flat-bottomed hole drilled through half the thickness mimicked a similar nonlinear …
