Notopleural Mutations Enhance Defects In Imaginal Disc Epithelial Morphogenesis And Macrochete Elongation Associated With Mutations In The Stubble-Stubbloid Locus, Robert Ruggiero Jan 2006

Notopleural Mutations Enhance Defects In Imaginal Disc Epithelial Morphogenesis And Macrochete Elongation Associated With Mutations In The Stubble-Stubbloid Locus, Robert Ruggiero

Electronic Theses and Dissertations

The Stubble-stubbloid locus encodes a transmembrane serine protease (Stubble) necessary for the proper formation of sensory bristles, and the morphogenesis of leg and wing epithelia. Genetic and cell biological analysis indicate a role for Stubble in actin cytoskeletal dynamics and cell shape changes in developing epithelia and bristles. Previously reported genetic interactions between Stubble and the Rho1 signaling pathway suggest Stubble influences actin cytoskeleton dynamics in developing imaginal discs through interactions with the Rho1 pathway. This work will discuss a genetic screen conducted to further investigate the role of Stubble in bristle and imaginal disc morphogenesis. From 50,000 EMS-mutagenized chromosomes …

Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler Jan 2006

Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler

Electronic Theses and Dissertations

Meta-analysis of 23 between-group direct observation studies of children with ADHD and typically developing peers indicates significant deficiencies in children with ADHD's ability to pay attention in classroom settings. Comparison with 59 single case design studies of children with ADHD suggests generalizability of between-group comparisons. Weighted regression analysis determined that several methodological differences – sample characteristics, diagnostic procedures, and observational coding schema – have significant effects on observed levels of attentive behavior in the classroom. Best case estimation indicates that after accounting for these factors, children with ADHD are on-task approximately 65% of the time compared to 85% for their …

Simplified Low Copy Number Dna Analysis By Post Pcr Purification, Pamela Smith Jan 2006

Simplified Low Copy Number Dna Analysis By Post Pcr Purification, Pamela Smith

Electronic Theses and Dissertations

Frequently evidentiary items contain an insufficient quantity of DNA to obtain complete or even partial DNA profiles using standard forensic gentotyping techniques. Here, various methods of post PCR purification were evaluated for their effects on the sensitivity of fluophore-based allelic detection. A method of post PCR purification is described which increases the sensitivity of standard 28 cycle PCR such that low copy number DNA templates (<100 pg DNA) can be analyzed. Full profiles were consistently obtained with as little as 20 pg template DNA without increased cycle number. In mock case type samples with dermal ridge fingerprints, genetic profiles were obtained by amplification with 28 cycles followed by post-PCR purification whereas no profiles were obtained without purification of the PCR product. Allele drop-out, increased stutter, and contamination (allele drop-in) typical of LCN analysis were observed. A single incident of contamination was observed in a reagent blank (not duplicated upon re-amplification) however, no contamination was observed in negative amplification controls.

Noise Characerization For Proposed Ucf Phyiscal Science Building Sites., Jorge Martinez Jan 2006

Noise Characerization For Proposed Ucf Phyiscal Science Building Sites., Jorge Martinez

Electronic Theses and Dissertations

Today's Advance Technology Facilities require low noise levels and increased noise monitoring. Ambient noise can interfere with the accuracy and precision of experiments and manufacturing processes. Therefore preconstruction site surveys are needed to develop strategies for mitigating noise. Vibration and low frequency electromagnetic fields are particularly detrimental for sensitive instruments, and they are also difficult to mitigate. However a large part of these costs can be avoided or minimized if a quiet building site is selected in the first place. Accelerometers and gauss meters combined with a computer for acquisition and analysis provide a low cost method of evaluating noise …

The Impact Of Mental Transformation Training Across Levels Of Automation On Spatial Awareness In Human-Robot Interaction, Sherri Rehfeld Jan 2006

The Impact Of Mental Transformation Training Across Levels Of Automation On Spatial Awareness In Human-Robot Interaction, Sherri Rehfeld

Electronic Theses and Dissertations

One of the problems affecting robot operators' spatial awareness involves their ability to infer a robot's location based on the views from on-board cameras and other electro-optic systems. To understand the vehicle's location, operators typically need to translate images from a vehicle's camera into some other coordinates, such as a location on a map. This translation requires operators to relate the view by mentally rotating it along a number of axes, a task that is both attention-demanding and workload-intensive, and one that is likely affected by individual differences in operator spatial abilities. Because building and maintaining spatial awareness is attention-demanding …

Every Cloud Has A Silver Lining: Positive Effects Of Deviant Coworkers, Gergana Markova Jan 2006

Every Cloud Has A Silver Lining: Positive Effects Of Deviant Coworkers, Gergana Markova

Electronic Theses and Dissertations

The purpose of this study was to recognize and explore the reactions of employees to a deviant coworker. Specifically, I focused on the potential positive effects for employees who are in the presence of a coworker perceived as deviant, dysfunctional, or negative. Consistent with a labeling perspective on deviance, I argued that an employee may become a deviant as a result of social construction, fostered either by observed norm violations or the perceived dissimilarity of this person. Drawing on diverse theories from social psychology and sociology, I hypothesized that in the presence of a deviant coworker, other employees may have …

Exploring Transient Identities: Deconstructing Depictions Of Gender And Imperial Ideology In The Oriental Travel Narratives Of Englishwomen, 1831-1915, Carrieanne Deloach

Electronic Theses and Dissertations

Englishwomen who traveled to the "Orient" in the Victorian era constructed an identity that was British in its bravery, middle-class in its refinement, feminine in appearance and speech and Christian in its intolerance of Oriental heathenism. Studying Victorian female travel narratives that described journeys to the Orient provides an excellent opportunity to reexamine the diaphanous nature of the boundaries of the public/private sphere dichotomy; the relationship between travel, overt nationalism, and gendered constructions of identity, the link between geographic location and self-definition; the power dynamics inherent in information gathering, organization and production. Englishwomen projected gendered identities in their writings, which …

Health Attitudes, Knowledge And Literacy Of Primary Caregivers With Elementary School Children, Susan Stuib Jan 2006

Health Attitudes, Knowledge And Literacy Of Primary Caregivers With Elementary School Children, Susan Stuib

Electronic Theses and Dissertations

Previous research has indicated that physical activity and healthy eating in elementary school children are the exception rather than the norm. Increased attention to the rising rates of childhood obesity, coupled with the recognition that changes in the school environment are critical to reducing this trend, has intensified the need to adopt better practices in school nutrition, physical activity and physical education. Apart from being physically active, children need to learn fundamental motor skills and develop health related physical fitness (cardiovascular endurance, muscular strength and endurance, flexibility, and body composition). Primary caregivers play an important part in developing and teaching …

Identification Of System Design Features That Affect Sickness In Virtual Environments, Julie Drexler Jan 2006

Identification Of System Design Features That Affect Sickness In Virtual Environments, Julie Drexler

Electronic Theses and Dissertations

The terms "simulator" and "VR" are typically used to refer to specific types of virtual environments (VEs) which differ in the technology used to display the simulated environment. While simulators and VR devices may offer advantages such as low cost training, numerous studies on the effects to humans of exposure to different VEs indicate that motion sickness-like symptoms are often produced during or after exposure to the simulated environment. These deleterious side effects have the potential to limit the utilization of VE systems if they jeopardize the health and/or safety of the user and create liability issues for the manufacturer. …

Analysis Of Aircraft Arrival Delay And Airport On-Time Performance, Yuqiong Bai

Electronic Theses and Dissertations

While existing grid environments cater to specific needs of a particular user community, we need to go beyond them and consider general-purpose large-scale distributed systems consisting of large collections of heterogeneous computers and communication systems shared by a large user population with very diverse requirements. Coordination, matchmaking, and resource allocation are among the essential functions of large-scale distributed systems. Although deterministic approaches for coordination, matchmaking, and resource allocation have been well studied, they are not suitable for large-scale distributed systems due to the large-scale, the autonomy, and the dynamics of the systems. We have to seek for nondeterministic solutions for …
