Arithmetic And Algebra Word Problems: Preservice Teachers' Content Knowledge, Attitudes, And Appreciation Of Students' Strategies, Marc D. Michael
Graduate Theses, Dissertations, and Problem Reports (ETD)
The arithmetic and algebraic word problem-solving skills, strategy preferences, and attitudes of preservice elementary and secondary teachers were investigated using a mixed methodology. Teachers' appreciations of student solutions were also examined. Prospective elementary teachers demonstrated flexible problem-solving behaviors while their secondary counterparts tended to prefer algebraic strategies exclusively. In general, the prospective teachers did not demonstrate a greater appreciation for those types of strategies that were typical to their level of training. When communicating the characteristics of an effective strategy, preservice teachers were concerned with organization and clarity rather than the mathematical relevance or appropriateness of the strategy itself. The …

Role Of The Host Cell In The Type Iii Translocation Of Pseudomonas Aeruginosa Exoenzyme S, Elizabeth A. Rucks
Role Of The Host Cell In The Type Iii Translocation Of Pseudomonas Aeruginosa Exoenzyme S, Elizabeth A. Rucks
Graduate Theses, Dissertations, and Problem Reports (ETD)
Exoenzyme S (ExoS) is a bifunctional toxin that is directly translocated into eukaryotic cells by the Pseudomonas aeruginosa (Pa) type III secretory (T3S) process. The N-terminal region of ExoS includes a GTPase activating protein (GAP) activity and the C-terminal region includes an ADP-ribosyltransferase (ADPRT) activity. The T3S-translocation (T3S-T) of ExoS allows the bacteria to directly manipulate host cell function, thereby contributing the virulence of Pa. A cell culture model of infection was developed to study the effects of ExoS on cell function, which differentiates the effects of ExoS expression from other bacterial effects. Previous studies found that ExoS inactivates cell …

Determination Of Rx Expression In The Adult Mouse Retina And Delineation Of The Rx Mediated Gene Regulation, Supriya A. Shah
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Retinal homeobox gene, Rx, is expressed in the anterior neural plate and the optic vesicle shows Rx expression throughout development. Rx is required for the proliferation of retinal progenitor cells during eye development.;Our expression studies of the Rx gene in the adult mouse retina show Rx expression in the Photoreceptor and inner nuclear layer of the adult neural retina and ciliarybody. The cotransfection assays indicate that Rx supports the transcription of neural retinal markers, as well as the RPE-markers. Therefore we characterize Rx as a proliferation marker for the entire optic vesicle region.;To determine the mechanism of Rx-mediated regulation …

Graduate Theses, Dissertations, and Problem Reports (ETD)
This study examines relationships between quality of life (QoL) and clinical outcomes, specifically A1C, in Type 2 diabetes patients. Type 2 diabetes patients at the outpatient clinics of a university hospital completed the SF-12 and the Audit of Diabetes Dependent Quality of Life (ADDQoL), and this was merged with a retrospective collection of his/her clinical and utilization data, including A1C. Usable response rate was 44.3% (n = 385). Mean A1C of respondents was 7.2 (+1.4), mean diabetes duration was 10.2 (+9.1), and 62.1% were obese. Only ADDQoL scores showed significant correlation with A1C (r = -0.19, p < 0.000). Hierarchical regression models were used to explain the effect of A1C on QoL controlling for demographics and clinical variables. A1C was not a significant predictor in any regression model, although univariate analyses indicated significantly lower ADDQoL and SF-12 PCS in the group with A1C > 7.0. Obesity was …
Dynamic Learning With Neural Networks And Support Vector Machines, Liang Tian
Dynamic Learning With Neural Networks And Support Vector Machines, Liang Tian
Graduate Theses, Dissertations, and Problem Reports (ETD)
Neural network approach has proven to be a universal approximator for nonlinear continuous functions with an arbitrary accuracy. It has been found to be very successful for various learning and prediction tasks. However, supervised learning using neural networks has some limitations because of the black box nature of their solutions, experimental network parameter selection, danger of overfitting, and convergence to local minima instead of global minima. In certain applications, the fixed neural network structures do not address the effect on the performance of prediction as the number of available data increases. Three new approaches are proposed with respect to these …
The Relation Of Psychopathic Characteristics And Malingering Of Ptsd, Elizabeth Ann Tyner
The Relation Of Psychopathic Characteristics And Malingering Of Ptsd, Elizabeth Ann Tyner
Graduate Theses, Dissertations, and Problem Reports (ETD)
Clinical lore suggests that psychopaths should be successful malingers, yet empirical evidence is inconclusive. To further investigate the relation of psychopathy and malingering, 56 undergraduate males were classified into three groups based on responses to one trauma screener (Posttraumatic Stress Diagnostic Scale; PDS, Foa, Cashman, Jaycox & Perry, 1997) and one psychopathy screener (Psychopathic Personality Inventory: Short Form; PPI: SF, Lilienfeld & Andrews, 1996). This multimodal simulation study examined the ability of participants high and low in psychopathic characteristics to successfully malinger PTSD.

Functional Analysis Of Atrpd3b, A Rpd3-Type Histone Deacetylase, In Arabidopsis, Lin Zhang
Graduate Theses, Dissertations, and Problem Reports (ETD)
Histone acetylation is modulated through the action of histone acetyltransferases and deacetylases, which play key roles in the regulation of eukaryotic gene expression. The RPD3 group of histone deacetylases constitutes the first class of histone deacetylases (HDACs) in eukaryotes.;In yeast and mammalian cells, it was found that RPD3 histone deacetylases are involved in the ageing and development. In contrast much less is known about the function of RPD3s in plant. Here I studied AtRPD3B, a RPD3-type histone deacetylase in Arabidopsis thaliana, to define its role in plant development and signal transduction pathways. Using the AtRPD3B: GUS transgenic Arabidopsis plants, I …

The Effects Of Explanatory Style On Bowling Performance., Paula M. Parker
The Effects Of Explanatory Style On Bowling Performance., Paula M. Parker
Graduate Theses, Dissertations, and Problem Reports (ETD)
As positive psychology gains more attention in psychology, sport psychology consultants will likely increase the study of this branch of psychological research. Foster, Hinkelman, and Watson (2003) suggested that an area of importance for sport psychology researchers is the development of a program to teach athletes how to be more optimistic in their explanatory style (ES). Some sport related research has shown that an optimistic explanatory style better equips individuals to bounce back from failure (e.g., Martin-Krumm et al.; Seligman et al., 1990), while other research has shown that a pessimistic style may be more beneficial to sport performance (e.g., …

Heating Ventilation And Air Conditioning Systems Condition Assessment Methodology, Anand Chandrashekaran
Graduate Theses, Dissertations, and Problem Reports (ETD)
Facilities (equipment) renewal is assigned low priority due to insufficient budgets in universities, colleges, hospitals, and industries. Insufficient funds lead to postponement of major repairs and replacements of facilities. This lack of investments combined with deterioration of facilities increases the maintenance problem. When funds become available, replacement and repair maintenance projects are carried out, at the cost of the critical ones, due to lack of information on facilities conditions and deficiencies. Thereby developing a facilities condition assessment methodology with a prioritization technique will help in utilizing the available resources effectively. This assessment identifies the physical condition and maintenance deficiencies of …
