Developmental Expression Of Xenopus Myosin 1d And Identification Of A Myo1d Tail Homology That Overlaps Th1, Janine M. Leblanc-Straceski, Anna Sokac, William Bement, Pablo Sobrado, Laura Lemoine

Chemistry Faculty Research & Creative Works

Xenopus laevis myosin 1d (XlMyo1d) is a member of the myosin I class, subclass 4. Members of this class are single headed, bind calmodulin light chains and have lipid binding domains in their tails. The rat myo1d homologue has been implicated in endosome vesicle recycling in epithelial cells. Mutations in the Drosophila myosin 1d homologue cause situs inversus in the abdomen. The XlMyo1d cDNA has been cloned and the derived amino acid sequence is 80% identical to the rat and human homologues. Sequence comparison revealed a novel isoform-specific tail homology embedded in the Tail Homology 1 (TH1) domain characteristic of …

Optimal Interpolation Grids For Accurate Numerical Solutions Of Singular Ordinary Differential Equations, Michael Margitus

Theses

Researchers are interested in three types of error: experimental error, truncation error, and interpolation error. This thesis will study the last. Given a differential equation g"(x) = f(x) and a fixed number of interpolation grid points, an optimation problem is formulated to minimize the difference between f(x) and its interpolating function, thus reducing the error between the actual solution and the approximated solution of the ODE. Using the Nelder-Mead Simplex Method, the optimal distribution of grid points that will minimize the error between the solution g and its approximated solution will be found. This technique will then be applied to …

Evaluating The Effect Of Peer Feedback On The Quality Of Online Discourse, Timothy D. Wells

Theses

This study explores the effect on discussion quality of adding a feedback mechanism that presents users with an aggregate peer rating of the usefulness of the participant's contributions in online, asynchronous discussion. Participants in the study groups were able to specify the degree to which they thought any posted comment was useful to the discussion. Individuals were regularly presented with feedback (aggregated and anonymous) summarizing peers' assessment of the usefulness of their contribution, along with a summary of how the individuals rated their peers. Results indicate that continuous, anonymous, aggregated feedback had no effect on either the students' or the …

Monitoring Reading Fluency Progress With The Use Of Graphs, Emily Lewandowski

Theses

Curriculum-Based Measurement (CBM) is a scientifically based approach used to

collect progress monitoring data, and is often used to monitor reading development.

Graphing a student's reading data over time allows educators to view the student's rate of progress, goal, and interventions. This leads to timely changes to ineffective instructional programs, often resulting in more academic success for students. Graphs can be a communication tool for educators to share progress data with students, parents, and other staff. The current need for educators to monitor student progress has resulted in an increasing need of programs that can be used in the educational …

Basement Membrane Proteoglycans: Modulators Par Excellence Of Cancer Growth And Angiogenesis., Renato V. Iozzo, Jason J. Zoeller, Alexander Nyström

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Proteoglycans located in basement membranes, the nanostructures underling epithelial and endothelial layers, are unique in several respects. They are usually large, elongated molecules with a collage of domains that share structural and functional homology with numerous extracellular matrix proteins, growth factors and surface receptors. They mainly carry heparan sulfate side chains and these contribute not only to storing and preserving the biological activity of various heparan sulfate-binding cytokines and growth factors, but also in presenting them in a more "active configuration" to their cognate receptors. Abnormal expression or deregulated function of these proteoglycans affect cancer and angiogenesis, and are critical …

Strategic Idealizations Of Science To Oppose Environmental Regulation" A Case Study Of Five Tmdl Controversies, David S. Caudill, Donald E. Curley

Faculty Publications

Proponents of environmental regulation have catalogued various strategies used by takeholders to delay or weaken regulatory efforts, including (1) manufacturing or magnifying uncertainty; (2) demanding “sound science” (and thereby imposing unreasonable standards of evidence); and (3) data quality initiatives that permit deconstruction of credible studies by highlighting inevitable assumptions, funding sources, and areas for further research. Such strategies can be termed “idealizations” of science insofar as they rely on an unrealistic image of good science as somehow capable of avoiding tentative conclusions, institutional interests, consensual assumptions, and the need for further research.

The question remains, however, when does an argument …

Feature Selection Of Microarray Data Using Genetic Algorithms And Artificial Neural Networks, Paul Yacci

Theses

Microarrays, which allow for the measurement of thousands of gene expression levels in parallel, have created a wealth of data not previously available to biologists along with new computational challenges. Microarray studies are characterized by a low sample number and a large feature space with many features irrelevant to the problem being studied. This makes feature selection a necessary pre-processing step for many analyses, particularly classification. A Genetic Algorithm -Artificial Neural Network (ANN) wrapper approach is implemented to find the highest scoring set of features for an ANN classifier. Each generation relies on the performance of a set of features …

Communicating Spirituality, Dying And A “Good Death” At The End-Of-Life: The Role Of Hospice Interdisciplinary Team Members, Jillian A. Tullis Owen

USF Tampa Graduate Theses and Dissertations

Hospices use interdisciplinary teams to aid patients and families as they cope with the imminence of death while helping them achieve a death free of physical and spiritual pain, also known as a good death. This study investigated the communication between hospice team members and their patients regarding spirituality, dying, death and a good death. Through 300 hours of participant observation and interviews with hospice staff at one large not-for-profit hospice in the Southeastern United States this project shows that team members understand patient's spirituality through a religious frame potentially compromising spiritual care. Talk between patients and their care …

Imaging Of Glioma Tumor With Endogenous Fluorescence Tomography, Dax S. Kepshire, Summer L. Gibbs-Strauss, Julia A. O'Hara, Michael Hutchins, Niculae Mincu, Frederic Leblond, Mario Khayat, Hamid Dehghani, Subhadra Srinivasan, Brian W. Pogue

Dartmouth Scholarship

Tomographic imaging of a glioma tumor with endogenous fluorescence is demonstrated using a noncontact single-photon counting fan-beam acquisition system interfaced with microCT imaging. The fluorescence from protoporphyrin IX (PpIX) was found to be detectable, and allowed imaging of the tumor from within the cranium, even though the tumor presence was not visible in the microCT image. The combination of single-photon counting detection and normalized fluorescence to transmission detection at each channel allowed robust imaging of the signal. This demonstrated use of endogenous fluorescence stimulation from aminolevulinic acid (ALA) and provides the first in vivo demonstration of deep tissue tomographic imaging …

Endurance And Exercise Physiology In Urosaurus Ornatus: Sex And Morph Differences?, Elizabeth Christine Foulkes

All-Inclusive List of Electronic Theses and Dissertations

Locomotory performance has been the focus of many ecological and evolutionary studies, and lizards have been a model system. While several studies have demonstrated interspecific differences in performance, few have examined intraspeciflc variation in performance and the suites of underlying physiological traits in tree lizards ( Uro.,·aurns ornatus) a species with alternative reproductive tactics that show variation in spatial use patterns. To assess the functional ecology of movement behaviors of male morphs and or females, I examined variation in exertion, plasma metabolites, plasma steroid hormones, and muscle fiber types in ornate tree lizards ( Urosaurus ornalus). In my study population, …

Quantile Regression: An Education Policy Research Tool, Edward B. Reeves, Jesse Lowe

Journal of Rural Social Sciences

Ordinary least squares regression is often used in education policy research. Unfortunately, OLS regression coefficients may mislead. In OLS models, the coefficients express the conditional mean relations among the variables. Still, what if this estimate of central tendency in the conditional distribution fails to convey important information about the distribution? Quantile regression is a statistical technique that allows variation in the conditional distribution to be examined. Therefore, it can be used to check the validity and applicable range of OLS coefficients. Following the method of Koenker and Hallock (2001), we compare OLS and quantile regression results, examining variables related to …

Vaksin Dna: Vaksin Generasi Keempat, Maksum Radji

Majalah Ilmu Kefarmasian

Vaccines have been developed for a range of different infectious diseases. The complex-ity of microbial infections requires novel approaches to vaccine design. The first-generation of vaccines were live attenuated pathogens. Because of safety concerns, the second-generation of vaccines, chemically or physically inactivated pathogens were later developed. Purified or synthetic proteins represent a third generation, and recent advances in molecular biology and genetic engineering have led to the development of the fourth vaccine generation, which includes DNA and virus vector-based vaccines. This review discusses on the genetic elements and construction of DNA vaccines, comparison of DNA vaccines and conventional vaccines, the …

"To Come Of Age In A Dry Place": Infrastructures Of Irrigated Agriculture In The Mexico-U.S. Borderlands, Casey Walsh

Journal of Rural Social Sciences

In the Mexico-U.S. borderlands the social uses of water are changing as the focus of the economy shifts slowly from agriculture to industry and services. This article discusses the changes to the physical and social infrastructures erected during the first half of the twentieth century to support a regime of accumulation based in irrigated cotton. Infrastructure is proposed as a particularly useful concept for drawing connections between these social, economic, and cultural changes, and emphasizing their materiality. The article draws upon the Social Structures of Accumulation and Regulation School literatures to explain the dynamics revealed through historical and ethnographic research …
