Gene Expression Of Components Of The Insulin/Insulin-Like Signaling Pathway In Response To Heat Stress In The Garter Snake, Thamnophis Elegans, Tonia S. Schwartz, Anne M. Bronikowski

Journal of the Iowa Academy of Science: JIAS

The insulin/insulin-like signaling (IIS) pathway is an evolutionary conserved molecular signaling pathway that regulates growth, reproduction, stress resistance, and longevity in response to nutrition and external stress. While the constituents of this pathway and their functions are relatively well understood in laboratory model animals, they have not been explored in many other organisms, with notable exceptions in the fisheries literature. We tested for the gene expression of four key components of this pathway in the garter snake (Thamnophis elegans) liver, and determine how the transcription of these components responds to heat stress. We found that the two insulin-like …

Synchronous Rotation In The Eclipsing Binary 68 Herculis Inferred From Doppler Shifts In Its Spectrum And Light Curve Modeling, Kenneth W. Mclaughlin, Janak Panthi

Journal of the Iowa Academy of Science: JIAS

Our differential photometry of the eclipsing binary 68 Herculis through V- and R-filters shows periodic minima consistent with a previously established period. As a function of its orbital motion, we report spectra over a limited wavelength range encompassing H-alpha 656.3 nm and helium 667.8 nm lines. Doppler shifts of both stars were resolved in H-alpha, while only the more massive star rendered the helium line with Doppler shifts that agree with the radial velocity we derive for it from the H-alpha profile. Sinusoidal curve-fits to the orbital dependence of the radial velocities imply circular orbits for both components, with amplitudes …

Improved Functional Prediction Of Hypothetical Proteins From Listeria Monocytogenes 08-5578, Michael J. Lagier, Brittany Bowman, Kelsey Brend, Katherine Hobbs, Michael Foggia, Mark Mcdaniel

Journal of the Iowa Academy of Science: JIAS

Listeria monocytogenes is a foodborne human pathogen responsible for listerosis. The genomes of several L. monocytogenes strains have been recently sequenced. The genome of L. monocytogenes 08-5578, which was in part responsible for a significant listerosis outbreak in 2008, contains an unexpectedly high percentage of protein-encoding genes (1,927 out of 3,161; 60.96%) autonomously annotated as hypothetical proteins. The aim of this study was to test whether a manual annotation strategy could be used to assign more meaningful functional names to the hypothetical proteins of 08-5578. A holistic, manual gene annotation strategy that utilized sequence homology, cellular localization predictions, structure-based evidence, …

The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris

Journal of the Iowa Academy of Science: JIAS

Although more than 85% of Iowa (USA) was covered by tallgrass prairie at the time of settlement by Europeans in the early 19th century, less than 0.1% remains. The Richard W. Pohl State Preserve at Ames (IA) High School, surrounded on three sides by structures, roads, and other development, protects 4 ha of tallgrass prairie. The preserve, commonly referred to as Ames High Prairie (AHP), was grazed but never plowed under private ownership until its acquisition by the Ames School District in 1959.

Although considered for development as a parking lot or football field in the 1960s, the residents of …

The Impact Of Digital Organization On Retention In College Algebra, Mary Benac Staniger

Dissertations and Theses @ UNI

This study examined the impact of digital organization for developmental mathematics students using technologically mediated tools in Beginning Algebra to increase retention for successful completion of College Algebra. The focus of the digital organization was student improvement in study skills and academic self-confidence throughout Beginning Algebra. These are two non-academic factors literature suggests are related to college students’ retention and performance. Study skills were measured by how students felt they could assess a mathematics problem, organize a solution and successfully complete assignments. Academic self-confidence was measured by student belief of the ability to perform well in mathematics. Mixed methods were …

Investigating The Effectiveness Of A Professional Development Program For Secondary Physics Teachers, Meghan Reynolds

Dissertations and Theses @ UNI

National studies have exposed a shortage of highly-qualified high school physics teachers, with over 25% of physics teaching vacancies in Iowa being very difficult to fill or unable to be filled. In an effort to improve the nation’s education system, there have been broad changes in the framework of what constitutes high-quality teaching which supports a trend away from traditional, lecture-based teaching methods and towards interactive, student-centered methods. This study analyzed the impact of a professional development program that aimed to prepare more high-quality high school physics teachers by building physics content knowledge through the use of reformed teaching techniques …

Culturally Relevant Pedagogy: Secondary Mathematics In An Urban Classroom, Julia Glissmann North

Honors Program Theses

Research and test scores have shown that African-American, Latino, Native American, and other minority students are underachieving in secondary mathematics. This is concerning not only to school personnel – who are under pressure to have students perform well on standardized tests – but also to the future of the country. When teachers adopt a culturally relevant pedagogy, diverse students will have a better opportunity to learn and retain mathematical content. When academic content is taught in a culturally relevant way, students are able to retain the information, improve their performance in school, and become more informed participants in society. Through …

A New Plant Record For Iowa: Lactuca Hirsuta (Asteraceae), Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

A new record of a native vascular plant, Lactuca hirsuta Muhlenberg ex Nuttall var. sanguinea (Bigelow) Fernald, is reported for Iowa. A specimen was collected in 1983 by the author during a study of the Swaledale railroad prairie in Cerro Gordo County, north central Iowa (Eddy 1988). The plant was inexplicably excluded in the species catalogue when a Swaledale railroad flora was published in 1988; thus, this “new” Iowa record in 2013 was collected 30 years prior. The voucher specimen was “re-discovered” by Dr. Neil A. Harriman at the University of Wisconsin-Oshkosh (OSH), and its identification verified.

Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek

Journal of the Iowa Academy of Science: JIAS

The Soil Management Assessment Framework (SMAF) was developed to help quantify soil quality/health effects of tillage, crop rotation, and other soil management practices. Our objective was to determine if the SMAF could detect soil health differences after growing a single winter triticale (X Triticosecale Wittmack) crop. Soil samples were collected from 0 to 7.5- and 7.5 to 15- cm depth increments during the 2003 – 2004 and 2004 – 2005 growing seasons near Ames and Lewis, IA, and analyzed for several potential soil quality indicators. The SMAF analysis showed higher soil quality ratings for surface than subsurface samples. It also …

This project also aligns with goals of the Iowa Mathematics and Science Education Partnership by helping …

Investigating Blended Learning In The High School Science Classroom, Holly Cassandra Hinkhouse

Dissertations and Theses @ UNI

Blended learning combines the best practices of online learning with face-to-face learning and some research has shown it to have positive benefits for students at the postsecondary level. However, few studies have reported the use of blended learning in the high school setting. This study used quantitative methods to measure student attitudes and learning of science content in both a treatment and control group consisting of 9th grade Physical Science classes. Students in the treatment group experienced one semester of blended learning by using online science modules to supplement their in-class learning while the control group continued to have only …
