Faculty Should Consider Peer Review As A Means Of Improving Students' Scientific Reasoning Skill, Briana Eileen Timmerman, Denise Strickland

Faculty Publications

The following article provides highlights of a larger body of work on the impact of peer review on undergraduate biology students’ scientific reasoning, scientific writing and attitudes. Results suggest that undergraduates, even freshman can be effective peer reviewers and that peer review improves scientific writing, content knowledge, and scientific reasoning skills. Students report peer review to be a beneficial experience both within the course and in terms of helping them to develop as aspiring scientists. Science faculty are therefore encouraged to consider incorporating peer review as a regular part of instruction.

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Catalase-peroxidase (KatG) is essential in Mycobacterium tuberculosis for oxidative stress management and activation of the antitubercular pro-drug isoniazid. The role of a unique distal side adduct found in KatG enzymes, involving linked side chains of residues Met255, Tyr229, and Trp107 (MYW), in the unusual catalase activity of KatG is addressed here and in our companion paper (Suarez, J., Ranguelova, K., Jarzecki, A. A., Manzerova, J., Krymov, V., Zhao, X., Yu, S., Metlitsky, L., Gerfen, G. J., and Magliozzo, R. S. (2009) J. Biol. Chem. 284, in press). The KatG[W107F] mutant exhibited severely reduced catalase activity yet normal peroxidase activity, and …

Fremont Site Distribution In The Upper Escalante River Drainage, Deborah C. Harris

Theses and Dissertations

A Fremont site distribution model for the Grand Staircase-Escalante National Monument during the period A.D. 500—1050/1100 posits that the Fremont subsistence strategy (seasonal mobility with dependence on both agriculture and hunting/foraging) is reflected by a site pattern of low-investment, seasonal or short-term habitation sites and isolated storage facilities at "lowland" elevations, and high-investment, long-term residence sites at "upland" elevations (McFadden 1998, 2000). This research assesses the model to evaluate its general precision, looking particularly at its success in modeling site locations for long-term residential versus seasonal/short-term habitation sites. A database including more than 400 Fremont sites was created to evaluate …

Compact Trench Based Bend And Splitter Devices For Silicon-On-Insulator Rib Waveguides, Yusheng Qian

Theses and Dissertations

Bends and splitters are typically the fundamental limiting waveguide components in reducing the size of planar lightwave circuits (PLCs) based on waveguides that have a low core/clad refractive index contrast, such as silicon-on-insulator (SOI) rib waveguides. This dissertation presents a solution to this problem in the form of trench-based bends (TBBs) and trench-based splitters (TBSs). Emphasis is placed on experimental demonstration of these components and their integration into practical devices exhibiting significant size reduction. First, a compact and low loss silicon-on-insulator rib waveguide 90◦ TBB is demonstrated based on an etched vertical interface and total internal reflection (TIR) realized by …

Ring-Substituted 4-Hydroxy-1h-Quinolin-2-Ones: Preparation And Biological Activity, Aidan Coffey, Et. Al.

Department of Biological Sciences Publications

In the study, a series of twelve ring-substituted 4-hydroxy-1H-quinolin-2-one derivatives were prepared. The procedures for synthesis of the compounds are presented. The compounds were analyzed using RP-HPLC to determine lipophilicity and tested for their photosynthesis-inhibiting activity using spinach (Spinacia oleracea L.) chloroplasts. All the synthesized compounds were also evaluated for antifungal activity using in vitro screening with eight fungal strains. For all the compounds, the relationships between the lipophilicity and the chemical structure of the studied compounds are discussed, as well as their structure-activity relationships (SAR).

Child Psychopathology, Parental Problem Perception, And Help-Seeking Behaviors, Jessica Curley Hankinson

USF Tampa Graduate Theses and Dissertations

Service underutilization is a major problem facing children with emotional and behavioral problems. In addition, parents are often the ones most responsible for seeking help for their children. However, many children do not receive adequate help because parents do not perceive a problem or do not recognize that a child is in need. The present study examined parental thresholds for problem perception and subsequent help-seeking decisions based on children's behaviors presented in a vignette. It was hypothesized that the type of child behavior, child and parent gender, and other parental characteristics would be associated with different thresholds for problem perception …

Evaluation Of An Innovative Technology For Treatment Of Water Contaminated With Perchlorate And Organic Compunds, Maureen A. Downen

Theses and Dissertations

Drinking water sources contaminated with both perchlorate and organic compounds have frequently been found in the U.S. Tailored granular activated carbon (T-GAC) is an innovative technology that is being evaluated to determine if it can more cost effectively remove perchlorate than conventional technologies. A question that has been raised is whether T-GAC can economically treat perchlorate-contaminated water that also has organic co-contaminants present. During a field study, trichloroethylene, an organic compound, and perchlorate were successfully removed by adsorption using a T-GAC/GAC system. These results motivated development of a model that could be applied to predict the cost and performance of …

Designing Renewable Energy Systems Via Systems Engineering Approaches, Lealon L. Martin

Amgen Seminar Series in Chemical Engineering

Increasing domestic and international demands for vital resources provide an impetus to develop novel energy-efficient technologies. This is a timely opportunity given some of the uncertainty over the availability and cost of fossil fuels in a period of growing energy demand in the U.S. and the rest of the world. This opportunity is also timely because of the growing concerns that several critical factors are driving climate change and generating the uncertainty of a sustainable future. However, we are entering this period of uncertainty with a vast storehouse of scientific discoveries and engineering innovations that give us reason to hope …

French Laïcité And The Popularity Of The Pacs, Ashley Gaylene Trupp Mattson

Theses and Dissertations

Civil unions are currently a divisive issues in the United States. Religion has historically influenced these debates. The French version of civil union, the Pacte Civil de Solidarité (Pacs,) was created in 1999 after seven years of debate. Many have written about the Pacs in the last decade. However, few have explored the direct correlations with France's relationship with Catholicism, her dominant religion that is doctrinally opposed to any sexual relationships outside of marriage. Laïcité has influenced a steady decrease in religiosity among French Catholics. This thesis explores the impact of this religious decline on the creation and surprising popularity …

Resampling And Editing Of Mischarged Trna Prior To Translation Elongation, Jiqiang Ling, Byung Ran So, Srujana S. Yadavalli, Hervé Roy, Shinichiro Shoji, Kurt Fredrick, Karin Musier-Forsyth, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Faithful translation of the genetic code depends on the GTPase EF-Tu delivering correctly charged aminoacyl-tRNAs to the ribosome for pairing with cognate codons. The accurate coupling of cognate amino acids and tRNAs by the aminoacyl-tRNA synthetases is achieved through a combination of substrate specificity and product editing. Once released by aminoacyl-tRNA synthetases, both cognate and near-cognate aminoacyl-tRNAs were considered to be committed to ribosomal protein synthesis through their association with EF-Tu. Here we show instead that aminoacyl-tRNAs in ternary complex with EF-Tu•GTP can readily dissociate and rebind to aminoacyl-tRNA synthetases. For mischarged species, this allows resampling by the product editing …

A Comparison Of Mathematical Discourse In Online And Face-To-Face Environments, Shawn D. Broderick

Theses and Dissertations

Many studies have been done on the impact of online mathematics courses. Most studies concluded that there is no significant difference in student success between online and face-to-face courses. However, most studies compared "traditional" online and face-to-face courses. Mathematics educators are advocating a shift from traditional courses to student-centered courses where students argue and defend the mathematics under the guidance of the teacher. Now, the differences in online and face-to-face student-centered mathematical courses merit a more in-depth investigation. This study characterized student mathematical discourse in online and face-to-face Calculus lab sections based off of a framework derived from an NCTM …

Alternating Links And Subdivision Rules, Brian Craig Rushton

Theses and Dissertations

The study of geometric group theory has suggested several theorems related to subdivision tilings that have a natural hyperbolic structure. However, few examples exist. We construct subdivision tilings for the complement of every nonsingular, prime alternating link and all torus links, and explore some of their properties and applications. Several examples are exhibited with color coding of tiles.
