Rhetorical Counterinsurgency: The Fbi And The American Indian Movement, Casey Ryan Kelly

Department of Communication Studies: Faculty Publications

In 2007, Federal Bureau of Investigation agents Joseph H. and John M. Trimbach published a tell-all book to expose the crimes of American Indian Movement (AIM) and dispel contemporary myths about Bureau conspiracies against Indian activists. The book provides an insiders’ account of the agents’ participation in the investigation of AIM and attempts to correct what they characterize as popular revisionist history accusing the FBI of gross injustices against Indian Country. The agents argue that as far as AIM is concerned, in the halls of academia, “There is a market for blurring the historical lines between fact and fiction” (2007, …

Extraction And Characterization Of Starch From Alkaline Cooked Corn Masa, Wajira Srinanda Ratnayake, Andrew B. Wassinger, David S. Jackson

Department of Food Science and Technology: Faculty Publications

Starch granules undergo structural and morphological changes during food processing unit operations as they interact with other food ingredients. This study was conducted to isolate and characterize starch granules from corn masa. A proteolytic enzyme, thermolysin, was effective in separating and isolating starch granules from endosperm proteins present in masa. The efficiency of starch extraction using thermolysin was 74% (w/w), and subsequent analyses showed that the isolated granules were free of contaminants. Starch samples were characterized using light microscopy, SEM, DSC, and XRD. Starch granules isolated from masa had undergone internal structural changes and some granules (≈40%) lost birefringence during …

Corroborative Study On Maize Quality, Dry-Milling And Wet-Milling Properties Of Selected Maize Hybrids, Kyung-Min Lee, Timothy J. Herrman, Lloyd Rooney, David S. Jackson, Jane Lingenfelser, Kent D. Rausch, John Mckinney, Chris Iiams, Linda Byrum, Charles R. Hurburgh Jr., Lawrence A. Johnson, Steven R. Fox

Department of Food Science and Technology: Faculty Publications

A corroborative study was conducted on the maize quality properties of test weight, pycnometer density, tangential abrasive dehulling device (TADD), time-to-grind on the Stenvert hardness tester (SHT), 100-kernel weight, kernel size distribution, and proximate composition as well as maize dry- and wet-millability by six participating laboratories. Suggested operating procedures were given to compare their measurements and provide the variance structure within and between laboratories and hybrids. Partial correlation coefficient among maize quality properties varied among laboratories. The repeatability and reproducibility precision values were acceptably low for the physical quality tests, except for TADD and SHT time-to-grind measurements. The yields of …

Deck-Mounted Steel Post Barrier System, John D. Reid, Ronald K. Faller, Jason A. Hascall

Department of Mechanical and Materials Engineering: Faculty Publications

An existing mountable safety barrier system, previously crash tested successfully on a wood bridge deck, was evaluated for use on a fiber reinforced plastic (FRP) bridge deck. In an attempt to avoid expensive full-scale crash testing, components of the existing system were evaluated using worst case conditions on two dynamic bogie crash tests and a series of computer simulations using nonlinear finite-element analysis. Simulation results closely approximated the physical results, with both displaying similar deformation, damage, and force levels. Both testing and simulation demonstrated that the barrier should function sufficiently if used on the FRP deck system. Further, the development …

Possible Use Of Foresight, Understanding, And Planning By Wolves Hunting Muskoxen, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

On Ellesmere Island in 2006, arctic wolves (Canis lupus arctos) were observed making a two-pronged approach to a herd of muskoxen (Ovibos moschatus) and, on another occasion, ambushing muskoxen. Both observations seemed to provide evidence that the wolves were using foresight, understanding, and planning. Although the possible use of insight and purposiveness has been documented in captive wolves, the present report is one of the few to document the possibility that freeranging wolves use these other three mental processes.

En 2006, sur l’île Ellesmere, des loups arctiques (Canis lupus arctos) ont été observés en …

Radical Change Accidentally: The Emergence And Amplification Of Small Change, Donde Ashmos Plowman, Lakami T. Baker, Tammy E. Beck, Mukta Kulkarni, Stephanie Thomas Solansky, Deandra Villarreal Travis

Department of Management: Faculty Publications

A decision to offer breakfast to homeless people led to radical change in a church and its environment. Existing theories of change do not fully explain observations from our qualitative study; however, complexity theory constructs suggest how and why such change emerged. We offer four key findings. First, the radical change was unintended, emergent, and slow. Second, destabilizing conditions helped small changes to emerge and become radical. Third, subsequent actions amplified an initial small change and, though not intended to do so, promoted radical change. Finally, the dynamic interaction of amplifying actions, contextual conditions, and small changes led to continuous …

Expression Analysis Of Rice Defense-Related Genes In Turfgrass In Response To Magnaporthe Grisea, Young-Ki Jo, Guo-Liang Wang, Michael J. Boehm

Department of Plant Pathology: Faculty Publications

Magnaporthe grisea (anamorph = Pyricularia grisea) causes blast on rice (Oryza sativa) and gray leaf spot on turfgrass. Gray leaf spot is a serious disease on St. Augustinegrass (Stenotaphrum secundatum), perennial ryegrass (Lolium perenne), and tall fescue (Festuca arundinacea). Virulence assays performed in this study revealed that M. grisea collected from rice could also cause disease on St. Augustinegrass and tall fescue. One rice isolate, Che86061, caused similar disease reactions on susceptible cultivars of rice and St. Augustinegrass and an incompatible interaction on resistant cultivars of both species. To explore whether …

The Ripple Effect: Biofuels, Food Security, And The Environment, Rosamond L. Naylor, Adam Liska, Marshall B. Burke, Walter P. Falcon, Joanne C. Gaskell, Scott D. Rozelle, Kenneth G. Cassman

Department of Agronomy and Horticulture: Faculty Publications

The integration of the agricultural and energy sectors caused by rapid growth in the biofuels market signals a new era in food policy and sustainable development. For the first time in decades, agricultural commodity markets could experience a sustained increase in prices, breaking the long-term price decline that has benefited food consumers worldwide. Whether this transition occurs—and how it will affect global hunger and poverty—remain to be seen. Will food markets begin to track the volatile energy market in terms of price and availability? Will changes in agricultural commodity markets benefit net food producers and raise farm incomes in poor …

Cell Wall Proteome In The Maize Primary Root Elongation Zone. Ii. Region-Specific Changes In Water Soluble And Lightly Ionically Bound Proteins Under Water Deficit1[W][Oa], Jinming Zhu, Sophie Alvarez, Ellen L. Marsh, Mary E. Lenoble, In-Jeong Cho, Mayandi Sivaguru, Sixue Chen, Henry T. Nguyen, Yajun Wu, Daniel P. Schachtman, Robert E. Sharp

Department of Agronomy and Horticulture: Faculty Publications

Previous work on the adaptation of maize (Zea mays) primary roots to water deficit showed that cell elongation is maintained preferentially toward the apex, and that this response involves modification of cell wall extension properties. To gain a comprehensive understanding of how cell wall protein (CWP) composition changes in association with the differential growth responses to water deficit in different regions of the elongation zone, a proteomics approach was used to examine water soluble and loosely ionically bound CWPs. The results revealed major and predominantly region-specific changes in protein profiles between well-watered and water-stressed roots. In total, 152 …

Map Location Of The Rpp1 Locus That Confers Resistance To Soybean Rust In Soybean, D. L. Hyten, G. L. Hartman, R. L. Nelson, R. D. Frederick, V. C. Concibido, J. M. Narvel, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean rust (SBR), caused by Phakopsora pachyrhizi, was first discovered in North America in 2004 and has the potential to become a major soybean [Glycine max (L.) Merr.] disease in the USA. Currently, four SBR resistance genes have been identifi ed but not mapped on the soybean genetic linkage map. One of these resistance genes is the Rpp1 gene, which is present in the soybean accession PI 200492. The availability of molecular markers associated with Rpp1 will permit marker-assisted selection and expedite the incorporation of this gene into U.S. cultivars. We compared simple sequence repeat (SSR) markers between …

Fertility Restoration Of The Sorghum A3 Male-Sterile Cytoplasm Through A Sporophytic Mechanism Derived From Sudangrass, Hoang V. Tang, Jeffrey F. Pedersen, Christine D. Chase, Daryl R. Pring

Department of Agronomy and Horticulture: Faculty Publications

Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations. We describe characteristics of a fertility restoration system derived from sudangrass, in which male-sterile individuals were observed at high frequency in backcross and F2-F3 segregating populations. Segregation analyses were consistent with a sporophytic restoration system involving two complementary genes. Pollen iodine staining in fertile …

Subsurface Characterization Using Textural Features Extracted From Gpr Data, R. S. Freeland, Lameck O. Odhiambo

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Subsurface conditions can be non-intrusively mapped by observing and grouping patterns of similarity within ground-penetrating radar (GPR) profiles. We have observed that the intricate and often visually indiscernible textural variability found within a complex GPR image possesses important parameters that help delineate regions of similar subsurface characteristics. In this study, we therefore examined the feasibility of using textural features extracted from GPR data to automate subsurface characterization. The textural features were matched to a “fingerprint” database of previous subsurface classifications of GPR textural features and the corresponding physical probings of subsurface conditions. Four textural features (energy, contrast, entropy, and homogeneity) …

Identification Of Functional Subclasses In The Dj-1 Superfamily Proteins, Ying Wei, Dagmar Ringe, Mark A. Wilson, Mary Jo Ondrechen

Department of Biochemistry: Faculty Publications

Genomics has posed the challenge of determination of protein function from sequence and/or 3-D structure. Functional assignment from sequence relationships can be misleading, and structural similarity does not necessarily imply functional similarity. Proteins in the DJ-1 family, many of which are of unknown function, are examples of proteins with both sequence and fold similarity that span multiple functional classes. THEMATICS (theoretical microscopic titration curves), an electrostatics-based computational approach to functional site prediction, is used to sort proteins in the DJ-1 family into different functional classes. Active site residues are predicted for the eight distinct DJ-1 proteins with available 3-D structures. …

Habitat Area Affects Arthropd Communities Directly And Indirectly Through Top Predators, Örjan Östman, Nicholas W. Griffin, Jared L. Strasburg, Jennifer A. Brisson, Alan R. Templeton, Tiffany M. Knight, Jonathan M. Chase

School of Biological Sciences: Faculty Publications

Both habitat area and predators are known to affect the diversity and composition of species that live in a locality. In addition, habitat area can influence the presence of predators, indirectly affecting the diversity of prey. Thus, habitat area may influence species diversity directly and indirectly through the presence of top predators. Here we examine the effects of habitat area and predators on the species richness and composition of a foliage living arthropod community in a fragmented complex of glades (small grassland patches within a forested matrix) in the Ozark Plateau, Missouri. We find that a top predator, the eastern …

Molecular Phylogenetics Of The Phyllostomid Bat Genus Micronycteris With Descriptions Of Two New Subgenera, Calvin A. Porter, Steven R. Hoofer, Chrissy A. Cline, Federico G. Hoffmann, Robert J. Baker

School of Biological Sciences: Faculty Publications

We analyzed DNA sequence variation in the cytochrome-b gene and intron 7 of the nuclear fibrinogen, B beta polypeptide gene for 45 specimens of the bat genus Micronycteris, including all currently recognized species except M. sanborni. Phylogenetic analyses of both data sets supported 4 primary lineages within Micronycteris, which we recognize as subgenera: Leuconycteris new subgenus (M. brosseti), Micronycteris Gray (M. megalotis, M. microtis, M. matses, and M. giovanniae), Schizonycteris new subgenus (M. minuta, M. schimdtorum, and M. sanborni), and Xenoctenes Miller (M. hirsuta). …

Alkaline Iron(Iii) Reduction By A Novel Alkaliphilic, Halotolerant, Bacillus Sp. Isolated From Salt Flat Sediments Of Soap Lake, Jarrod Pollock, Karrie A. Weber, Joe Lack, Laurie A. Achenbach, Melanie R. Mormile, John D. Coates

School of Biological Sciences: Faculty Publications

A halotolerant, alkaliphilic dissimilatory Fe(III)-reducing bacterium, strain SFB, was isolated from salt flat sediments collected from Soap Lake, WA. 16S ribosomal ribonucleic acid gene sequence analysis identified strain SFB as a novel Bacillus sp. most similar to Bacillus agaradhaerens (96.7% similarity). Strain SFB, a fermentative, facultative anaerobe, fermented various hexoses including glucose and fructose. The fructose fermentation products were lactate, acetate, and formate. Under fructose-fermenting conditions in a medium amended with Fe(III), Fe(II) accumulated concomitant with a stoichiometric decrease in lactate and an increase in acetate and CO₂. Strain SFB was also capable of respiratory Fe(III) reduction with …

Flagellar Motility And Structure In The Hyperthermoacidophilic Archaeon Sulfolobus Solfataricus, Zalán Szabó, Musa Sani, Maarten Groeneveld, Benham Zolghadr, James Schelert, Sonja-Verena Albers, Paul H. Blum, Egbert J. Boekema, Arnold J.M. Driessen

School of Biological Sciences: Faculty Publications

Flagellation in archaea is widespread and is involved in swimming motility. Here, we demonstrate that the

structural flagellin gene from the crenarchaeaon Sulfolobus solfataricus is highly expressed in stationary-phasegrown

cells and under unfavorable nutritional conditions. A mutant in a flagellar auxiliary gene, flaJ, was

found to be nonmotile. Electron microscopic imaging of the flagellum indicates that the filaments are composed

of right-handed helices.

Spatiotemporal Variations In Growing Season Exchanges Of Co2, H2o, And Sensible Heat In Agricultural Fields Of The Southern Great Plains, Marc L. Fischer, Dave P. Billesbach, Joseph A. Berry, William J. Riley, Margaret S. Torn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Climate, vegetation cover, and management create finescale heterogeneity in unirrigated agricultural regions, with important but not well quantified consequences for spatial and temporal variations in surface CO2, water, and heat fluxes. Eddy covariance fluxes were measured in seven agricultural fields—comprising winter wheat, pasture, and sorghum—in the U.S. Southern Great Plains (SGP) during the 2001–03 growing seasons. Land cover was the dominant source of variation in surface fluxes, with 50%–100% differences between fields planted in winter–spring versus fields planted in summer. Interannual variation was driven mainly by precipitation, which varied more than twofold between years. Peak aboveground biomass and growing season …

Bk Virus Infection In A Renal Transplant Saudi Child, Mohamed Maghrabi, Dalia Marwan, Abimbola O. Osoba

Saudi Medical Journal

BK human polyomavirus BKV causes an asymptomatic primary infection in children, but later, establishes latency mainly in the urinary tract. Virus-host interactions influencing persistence and pathogenicity are not well-understood. We present here a 12-year-old Saudi boy, who had renal transplant in Egypt. Seven months later, he was admitted to our Pediatric Nephrology Unit as a case of renal impairment. He developed BKV infection, diagnosed and successfully managed in our hospital. This case demonstrates the expanding clinical importance of BKV in a post renal transplant patient. This virus can be detected in transitional cells in the urine decoy cells using cytology. …

A multiple- case study of Taiwanese and Chinese electronics industries is presented to demonstrate how and why different firms apply different technology strategies in alliances and supply chain formations. Due to intense global competition, technological integration, and product life-cycle time compression, Taiwanese and Chinese high-technology firms are suggested to formulate and implement a coherent technology strategy to enhance their global competitiveness. By applying an integrated framework based on major theoretical perspectives studying the formulation and implementation of …

An Analysis Of The D Programming Language, Sumanth Yenduri, Louise Perkins, Md. Sarder

Journal of International Technology and Information Management

The C language and its derivatives have been some of the dominant higher-level languages used, and the maturity has stemmed several newer languages that, while still relatively young, possess the strength of decades of trials and experimentation with programming concepts. While C++ was a major step in the advancement from procedural to object-oriented programming (with a backbone of C), several problems existed that prompted the development of new languages. This paper focuses on one such language: D. D was designed as a potential successor to C++, supporting most features of C++’s class design and modifications intended to ease common program …

In addition, this paper illustrates examples of how the technology change and the technological convergence (Internet, computers, and mobile telephony) affected and activated the proliferation of these alliances. The entry of I-mode and Vodafone Live! in the Greek market caused an increase in the number of …

Improving Credit Card Operations With Data Mining Techniques, Malini Krishnamurthi

Journal of International Technology and Information Management

Consumer credit is ubiquitous and lending poses credit risk – the risk of economic loss due to the failure of a borrower to repay according to the terms of his or her contract with the lender. And so, managing credit risk entails estimating the potential ability of borrowers to repay their debts. Researchers have sought to identify factors that contribute to consumer risk, by using quantitative models. However, the presence of data mining techniques to identify credit risk cannot be ignored. There is a paucity of research to demonstrate the use of data mining techniques in this context, and such …

Fostering The Development Of Vocabulary Knowledge And Reading Comprehension Though Contextually-Based Multiple Meaning Vocabulary Instruction, J. Ron Nelson, Scott A. Stage

Department of Special Education and Communication Disorders: Faculty Publications

The primary purpose of this study was to assess the effects of contextually-based multiple meaning (i.e., words with multiple meanings) vocabulary instruction on the vocabulary knowledge and reading comprehension of students. Third and 5th grade students received either contextually-based multiple meaning vocabulary instruction embedded in the standard language arts instruction offered to all students over a three-month period or the standard language arts instruction alone (i.e., non-specific treatment). Students who received the contextually-based multiple meaning instruction generally showed statistically and educationally significant gains in their vocabulary knowledge and reading comprehension relative to students who did not. These gains were most …

Characterizations Of Pseudo-Codewords Of Ldpc Codes, Ralf Koetter, Wen-Cheng W. Li, Pascal O. Vontobel, Judy L. Walker

Department of Mathematics: Faculty Publications

An important property of high-performance, low complexity codes is the existence of highly efficient algorithms for their decoding. Many of the most efficient, recent graph-based algorithms, e.g. message passing algorithms and decoding based on linear programming, crucially depend on the efficient representation of a code in a graphical model. In order to understand the performance of these algorithms, we argue for the characterization of codes in terms of a so called fundamental cone in Euclidean space which is a function of a given parity check matrix of a code, rather than of the code itself. We give a number of …

Genetic Analysis Of A Novel Alaska Barley Yellow Dwarf Virus In The Family Luteoviridae, N.L. Robertson, Roy C. French

Department of Plant Pathology: Faculty Publications

A new plant virus belonging to the family Luteoviridae and isolated from diseased oat (Avena sativa L.) plants was discovered in Alaska in 2003. Even though plants with red/orange leaves were indicative of barley yellow dwarf disease, they were not reactive to specific antibodies corresponding to barley yellow dwarf virus (BYDV)-MAV, -PAV, -SGV, and cereal yellow dwarf virus-RPV from enzyme-linked immunosorbent assays (ELISA). An alternative RT-PCR assay that incorporated Shu-F/Yan-R primers for detection of BYDV-MAV, -PAS, -PAV, and SGV was effective in producing ~830-nt fragments that contained genomic sequences to the 3’-terminus of the polymerase gene (ORF 2), the …
