Using Questioning To Facilitate Discussion Of Science Teaching Problems In Teacher Professional Development, Meilan Zhang, Mary Lundeberg, Tom J. Mcconnell, Matthew J. Koehler, Jan Eberhardt

Interdisciplinary Journal of Problem-Based Learning

Previous research has shown that questioning is a key strategy that facilitators use to promote discussion in Problem-Based Learning (PBL). Yet, there is a lack of detailed understanding on what questions facilitators ask and how those questions affect discussion. In this study we examined different types of questions that experienced facilitators asked to promote discussion of teaching problems in professional development for science teachers. We videotaped six PBL sessions facilitated by three pairs of experienced facilitators. Data analysis showed that facilitators asked a set of questions to initiate and advance PBL discourse, including questions to solicit ideas, to reframe ideas, …

The Effects Of Seasonality And Land Use On Microbe Populations In Three Ecological Areas, Rachel E. Hutchins

McNair Scholars Research Journal

The Huron River watershed is comprised of three primary land uses: agricultural, natural, and urban. Land usage affects the biological and chemical conditions within the watershed, therefore affecting water quality. Recent studies have provided evidence that water quality can be assessed by examining the composition of the microbial communities found in biofilms. In this study we analyzed and compared samples collected from a natural site and urban site over the course of three seasons; fall (August), winter (December), and spring (April). Microbial diversity was determined by isolating, amplifying, and genotyping the 16S rRNA gene. The results show that microbial community …

Incomplete Spring Turnover In Small Deep Lakes In Se Michigan, Lisa Denys

McNair Scholars Research Journal

While temperate lakes are commonly thought to turnover twice annually, in the fall and the spring, there are several factors that can reduce the probability of turnover. Whether or not a lake turns over has important implications for nutrient dynamics and food webs. In this study, we investigated several small deep lakes in SE Michigan to determine whether spring turnover had occurred. One factor affected by lake turnover is the distribution of oxygen in the lake. Lakes receive oxygen from the atmosphere at their surface and from small plant-like organisms called phytoplankton within the body of the lake. Photosynthesizing phytoplankton …

The Sensitivity In Methods Of Measuring Conditioned Flavor Aversions And Conditioned Flavor Preferences, Jacinda T. Bunting-Dady

McNair Scholars Research Journal

This project investigated a multiple measurement procedure to assess conditioned flavor aversions (CFA) and conditioned flavor preferences (CFP) in male albino rats. Volume consumed is currently the most common and often the sole method used. Most studies employ group designs, whereas this study used a single-subject design to compare behavior patters and responses between individual rats. Response measurements include: total licks, lick rate, lick patterns, volume (ml) consumed, volume (ml) per lick. Strong CFA showed consistent decreases in total licks, lick rate, total volume, ad volume per lick. CFP was evident, although not consistent, in total licks, lick rate, total …

The Synergistic Effects Of Probiotic Microorganisms On The Microbial Production Of Butyrate In Vitro, Khadija A. Abbas

McNair Scholars Research Journal

Butyrate producing microbiota perform a number of activities important in supporting the normal function of the human gastrointestinal tract. The goal of this study was to determine the synergistic effects of lactate- and butyrate-producing bacteria on butyrate production in vitro co-culture. PCR was used to detect the genes butyrate kinase and butyryl-CoA transferase that contribute to butyrate production, in a panel of representative gut microbiota. Preliminary data suggested that two Clostridium sp. (ASF 500 and ASF 502) and one Eubacterium sp. (ASF492) possessed at least one of these genes for butyrate production. Co-culture experiments mixing a lactate-producer with a butyrate-producer …

Practitioners' Views Of Effective Treatment Options For Childhood Trauma, Mary Sue Storie

McNair Scholars Research Journal

In today's society the number of children who experience childhood trauma is increasing significantly. As a result of this increase, the number of people seeking treatment is also on the rise. For this study, data were collected using both qualitative interviews (N=10) and an online quantitative survey (N=32). Practitioners' views of effectiveness ranged from both more traditional treatments to emerging alternative treatments. Recent knowledge from brain research shows trauma impacts both the left and right side of the brain. Many practitioners noted effective treatment needs to be comprehensive. This is supported by literature recommending modalities that work with the effect …

Does Rac Gtpase Play A Role In Epha4 Signaling In Xenopus Embroys?, Ashley Durand

McNair Scholars Research Journal

In embryonic development, many cells migrate in order to correctly form new structures. One way that guidance of this migration occurs is via a repulsion mechanism involving the Eph family of receptors. Signaling through these receptors activates the repulsive mechanism that limits which tissues can interact with each other. The repulsion mechanism is not well understood, but involves the reorganization of the actin cytoskeleton and a loss of cell-cell adhesion. Activation of the EphA4 signaling pathway in Xenopus laevis embryos has been shown to cause the repulsion mechanism. the Rho family of GTPases consisting of Cdc42, Rho, and Rac, has …

Report On Information Literacy And The Mic: Teaching Higher Education Students Critical Research Skills Using Hip Hop Lyricism, Dara Walker

McNair Scholars Research Journal

Many professors expect undergraduate students to have basic research skills. However, they soon lear that their students are unable to find, sort, and analyze information for research papers and projects. To help students attain these skills, university librarians develop course-related information literacy (IL) sessions for both undergraduate and graduate classes. In this study, I explored the differences and similarities in the objectives, teaching aides, ad final assignments of information literacy instruction which uses the thematic content in conscious hip hop lyricism to reinforce skills learned as compared to other methods. Understanding the differences and similarities may encourage librarians to make …

Development And Verification Of An Analytical Algorithm To Predict Absorbed Dose Distributions In Ocular Proton Therapy Using Monte Carlo Simulations, Nicholas C. Koch, Wayne D. Newhauser

Faculty Publications

Proton beam radiotherapy is an effective and non-invasive treatment for uveal melanoma. Recent research efforts have focused on improving the dosimetric accuracy of treatment planning and overcoming the present limitation of relative analytical dose calculations. Monte Carlo algorithms have been shown to accurately predict dose per monitor unit (D/MU) values, but this has yet to be shown for analytical algorithms dedicated to ocular proton therapy, which are typically less computationally expensive than Monte Carlo algorithms. The objective of this study was to determine if an analytical method could predict absolute dose distributions and D/MU values for a variety of treatment …

A Duplicate Gene Rooting Of Seed Plants And The Phylogenetic Position Of Flowering Plants, Sarah Mathews, Mark D. Clements, Mark A. Beilstein

Faculty Publications

Flowering plants represent the most significant branch in the tree of land plants, with respect to the number of extant species, their impact on the shaping of modern ecosystems and their economic importance. However, unlike so many persistent phylogenetic problems that have yielded to insights from DNA sequence data, the mystery surrounding the origin of angiosperms has deepened with the advent and advance of molecular systematics. Strong statistical support for competing hypotheses and recent novel trees from molecular data suggest that the accuracy of current molecular trees requires further testing. Analyses of phytochrome amino acids using a duplicate gene-rooting approach …

Organization, Structure, And Assembly Of Alpha-Carboxysomes Determined By Electron Cryotomography Of Intact Cells, Cristina V. Iancu, Dylan M. Morris, Zhicheng Dou, Sabine Heinhorst, Gordon C. Cannon, Grant J. Jensen

Faculty Publications

Carboxysomes are polyhedral inclusion bodies that play a key role in autotrophic metabolism in many bacteria. Using electron cryotomography, we examined carboxysomes in their native states within intact cells of three chemolithoautotrophic bacteria. We found that carboxysomes generally cluster into distinct groups within the cytoplasm, often in the immediate vicinity of polyphosphate granules, and a regular lattice of density frequently connects granules to nearby carboxysomes. Small granular bodies were also seen within carboxysomes. These observations suggest a functional relationship between carboxysomes and polyphosphate granules. Carboxysomes exhibited greater size, shape, and compositional variability in cells than in purified preparations. Finally, we …

Uncoupling Of Inflammation And Insulin Resistance By Nf-Κb In Transgenic Mice Through Elevated Energy Expenditure, Tianyi Tang, Jin Zhang, Jun Yin, Jaroslaw Staszkiewicz, Barbara Gawronska-Kozak, Dae Young Jung, Hwi Jin Ko, Helena Ong, Jason K. Kim, Randy Mynatt, Roy J. Martin, Michael Keenan, Zhanguo Gao, Jianping Ye

Faculty Publications

To study the metabolic activity of NF-κB, we investigated phenotypes of two different mouse models with elevated NF-κB activities. The transcriptional activity of NF-κB is enhanced either by overexpression of NF-κB p65 (RelA) in aP2-p65 mice or inactivation of NF-κBp50 (NF-κB1) through gene knock-out. In these models, energy expenditure was elevated in day and night time without a change in locomotion. The mice were resistant to adulthood obesity and diet-induced obesity without reduction in food intake. The adipose tissue growth and adipogenesis were inhibited by the elevated NF-κB activity. Peroxisome proliferator-activator receptor γ expression was reduced by NF-κB at the …

Phenotypic Variance Predicts Symbiont Population Densities In Corals: A Modeling Approach, Robert Van Woesik, Kazuyo Shiroma, Semen Koksal

Ocean Engineering and Marine Sciences Faculty Publications

We test whether the phenotypic variance of symbionts (Symbiodinium) in corals is closely related with the capacity of corals to acclimatize to increasing seawater temperatures. Moreover, we assess whether more specialist symbionts will increase within coral hosts under ocean warming. The present study is only applicable to those corals that naturally have the capacity to support more than one type of Symbiodinium within the lifetime of a colony; for example, Montastraea annularis and Montastraea faveolata. Methodology/Principal Findings: The population dynamics of competing Symbiodinium symbiont populations were projected through time in coral hosts using a novel, discrete time optimal-resource model. Models …

Universal Features Of Post-Transcriptional Gene Regulation Are Critical For Plasmodium Zygote Development, Gr Mair, E Lasonder, Ls Garver, Bmd Franke-Fayard, Et Al

School of Biomedical Sciences

A universal feature of metazoan sexual development is the generation of oocyte P granules that withhold certain mRNA species from translation to provide coding potential for proteins during early post-fertilization development. Stabilisation of translationally quiescent mRNA pools in female Plasmodium gametocytes depends on the RNA helicase DOZI, but the molecular machinery involved in the silencing of transcripts in these protozoans is unknown. Using affinity purification coupled with mass-spectrometric analysis we identify a messenger ribonucleoprotein (mRNP) from Plasmodium berghei gametocytes defined by DOZI and the Sm-like factor CITH (homolog of worm CAR-I and fly Trailer Hitch). This mRNP includes 16 major …

Open Notebook Science Challenge Solubilities Of Organic Compounds In Organic Solvents, Andrew Lang, Jean-Claude Bradley, Cameron Neylon, Rajarshi Guha, Antony J. Williams, Bill Hooker, Brent Friesen

College of Science and Engineering Faculty Research and Scholarship

The Open Notebook Science Solubility Challenge Solubility is an important consideration for many chemistry applications. Synthetic chemists usually use a solvent to perform reactions and knowledge of the solubility of the starting materials or products can be very useful to pick an appropriate solvent. Analytical chemists can use solubility to design separation techniques and factor in dynamic range considerations. Physical chemists can create and evaluate their models of how molecules interact in the solubilization and precipitation processes. Solubility data can be obtained from a variety of online and offline sources. As with all chemical data, it can be a challenge …
