I Can Be Silent And Be Saying A Lot: Teachers' Racial Literacy In A Southern Elementary School, Kimberly J. Howard Jan 2013

I Can Be Silent And Be Saying A Lot: Teachers' Racial Literacy In A Southern Elementary School, Kimberly J. Howard

Theses and Dissertations

In order to better understand how teachers make sense of race in schools today, this ethnographic study explores the following research question: How do teachers in this school make sense of race, and how does the spatiality of the school inform this process? The study was conducted over a 14-month period in a southern elementary school and is presented as a poetic, narrative, and thematic analysis of the connections between the geographic location of this particular school and the teachers' practices, pedagogies, and conversations about race both inside their classrooms and in other school spaces. This study demonstrates how teachers' …

Only From Montana: A Family's Experience Eating Locally, Emily Joan Wendler Jan 2013

Only From Montana: A Family's Experience Eating Locally, Emily Joan Wendler

Graduate Student Theses, Dissertations, & Professional Papers

This is a 30-minute radio documentary on one family’s experience eating all locally grown food, for two weeks in September of 2012, and two weeks during January 2013. For the project we considered locally grown food as food grown and processed in Montana. If the food was grown here, then left to be processed in another state, it did not count as local. The participants were a family of three from Missoula, Montana—a Mom, Dad, and their 2-year-old son. The point of the project was to answer the question: What is it like for a family, who normally does not …

Veterinary Specialty Certification: Analyzing The Value Of Certification Through The American Board Of Veterinary Practitioners, Jeff Allen

MPA/MPP/MPFM Capstone Projects

When it comes to professional certification a number of potential benefits can be cited by the organizations that offer them. Self-improvement, recognition by peers, public benefit and enhanced career opportunities are just a few of the frequently mentioned values associated with certification programs. This study was conducted to identify the primary benefits of certification for the American Board of Veterinary Practitioners (ABVP) by recording and analyzing the perceived value of ABVP certification within the veterinary community. An online survey was developed to collect data from ABVP certified and non-certified veterinarians, relying heavily on the Perceived Value of Certification Tool (PVCT). …

Salamander Hox Clusters Contain Repetitive Dna And Expanded Non-Coding Regions: A Typical Hox Structure For Non-Mammalian Tetrapod Vertebrates?, Stephen Randal Voss, Srikrishna Putta, John A. Walker, Jeremiah J. Smith, Nobuyasu Maki, Panagiotis A. Tsonis

Biology Faculty Publications

Hox genes encode transcription factors that regulate embryonic and post-embryonic developmental processes. The expression of Hox genes is regulated in part by the tight, spatial arrangement of conserved coding and non-coding sequences. The potential for evolutionary changes in Hox cluster structure is thought to be low among vertebrates; however, recent studies of a few non-mammalian taxa suggest greater variation than originally thought. Using next generation sequencing of large genomic fragments (>100 kb) from the red spotted newt (Notophthalamus viridescens), we found that the arrangement of Hox cluster genes was conserved relative to orthologous regions from other vertebrates, but the …

Peptides Inhibiting Angiotensin I-Converting Enzyme Derived From Edible Mushrooms / Lau Ching Ching, Ching Ching Lau

Student Works (2010-2019)

Hypertension is one of the major health problems worldwide. Bioactive peptides that inhibit angiotensin I-converting enzyme (ACE) in the blood pressure regulation system (renin-angiotensin system) can contribute to the prevention and treatment of hypertension. Mushroom species studied are high in protein content, which makes them potentially a good source of antihypertensive peptides. Among the nine edible mushrooms evaluated, protein extracts from Pleurotus cystidiosus (E1Pc and E5Pc) and Agaricus bisporus (E1Ab and E3Ab) exhibited high levels of ACE inhibitory activity. The protein extracts were fractionated by reverse-phase high performance liquid chromatography (RPHPLC) into six fractions each. Fraction 3 from E5Pc (E5PcF3) …

Student Works (2010-2019)

The extensive use of commercial activated carbon as an adsorbent for the purification of industrial effluent is not economically feasible due its high operational cost. Therefore, this research has been undertaken to explore the potential of certain agro based residues to produce suitable adsorbent for scavenging divalent cations of lead (Pb), copper (Cu) and manganese (Mn) from waste water to meet specific industrial requirements. In this regard, powdered activated carbons (PAC) were produced from cellulosic precursors namely kenaf core (KC) and kenaf fiber (KF) and granular activated carbon (GAC) from mangostene fruit shell (MFS) by physio-chemical activation.

Student Works (2010-2019)

Methane (CH4) is an important greenhouse gas with a global warming potential 25 times higher than carbon dioxide (CO2). Landfill is a one of the major contributor to global CH4 emission and is estimated to be 500-800 Mt CO2 eq/year. Previous studies have shown that microbial oxidation of CH4 in landfill cover soil can be enhanced using substrates that are rich in organic matter, such as compost. Methanotrophs are group of bacteria that utilize CH4 as its sole carbon and energy source. Therefore this study is aimed to characterize the physiochemical properties of biocover material,while identifying the potential methanotrophic bacteria …

Toxoplasmosis is a disease caused by a single-celled protozoan parasite known as Toxoplasma gondii. It infects approximately one-third of the world’s population. The definitive hosts of this obligate intercellular parasite are feline family members; but it is widespread in human and many warm-blooded animals, particularly farm animals. The disease causes critical symptoms in infants, pregnant women, and fetuses and there is still an urgent need new more effective therapeutic, diagnostic and bioimaging compounds as well as affordable production methods amenable to upscaling. A plant-based recombinant antibody against Toxoplasma antigen may offer a potential approach in developing strategies to produce such …
