Are They Ready To Make The Switch? Results Of The Wsu Libraries Survey On Electronic And Print Collections, Cathy Moore-Jansen, Judith A. Wolfe

University of Nebraska-Lincoln Libraries: Presentations

A recent survey of Wichita State University faculty, staff, and students by the WSU Libraries shows the university community far from consensus on the issue of print versus electronic journals and other resources. The survey, made available to the entire campus via the Web, provides an in-depth look at the importance of materials in different formats, how print and electronic journals are located and used, the interest in alternative delivery methods, and the level of support for canceling subscriptions or buying fewer books to maintain or add electronic access. The responses from 381 users have been analyzed using statistical software …

Weast Nile Virus Serosurveillance In Iowa White-Tailed Deer (1999-2003), Julian Santatella, Robert Mclean, Jeffrey S. Hall, James S. Gill, Richard A. Bowen, Harlo H. Hadow, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

Sera from white-tailed deer (Odocoileus virginianus) were collected in Iowa during the winter months (1999-2003), 2 years before and after West Nile virus (WNV) was first reported in Iowa (2001), and were analyzed for antibodies to WNV. Samples from 1999 to 2001 were antibody negalive by blocking enzyme-linikedI immunosorbent assay (bELISA) and plaque reduction neutralization test (PRNT₉₀). Prevalence derived from bELISA (2002, 12.7%; 2003. 11.2%) and WNV PRNT₉₀ (2002,7.9%; 2003, 8.5%) assays were similar. All sanlples were negative for antibodies against St. Louis encephalitis virus as determined by PRNT₉₀. Antibodies to flaviviruses were …

Finite Element Analysis Of Covered Microstents, Linxia Gu, Swadeshmukul Santra, Robert A. Mericle, Ashok V. Kumar

Department of Mechanical and Materials Engineering: Faculty Publications

Currently available neuroendovascular devices are inadequate for effective treatment of many wide-necked or fusiform intracranial aneurysms and intracranial carotid-cavernous fistulae (CCF). Placing a covered microstent across the intracranial aneurysm neck and CCF rent could restore normal vessel morphology by preventing blood flow into the aneurysm lumen or CCF rent. To fabricate covered microstents, our research group has developed highly flexible ultra thin (~150 μm) silicone coverings and elastomerically captured them onto commercially available metal stents without stitching. Preliminary in vivo studies were conducted by placing these covered microstents in the common carotid artery of rabbits. The feasibility of using covered …

Religiosity And Prosocial Behaviours In Adolescence: The Mediating Role Of Prosocial Values, Sam A. Hardy, Gustavo Carlo

Department of Psychology: Faculty Publications

This study examined the hypothesis that religiosity would be differentially related to six types of adolescent prosocial behavior, and that these relations would be mediated by the prosocial value of kindness. Self-report data were collected from 142 high school students (63 per cent female; 91 per cent White; M age = 16.8, S =.80). Religiosity was a significant positive predictor of kindness, as well as compliant, anonymous and altruistic prosocial behavior, but not public, dire and emotional prosocial behavior. Associations between religiosity and both compliant and altruistic prosocial behaviors were mediated by kindness. Direct and indirect paths were found between …

Nitrogen Use Efficiency – State Of The Art, Achim R. Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Nitrogenous fertilizers have contributed much to the remarkable increase in food production that has occurred during the past 50 years (Smil, 2001). Globally, however, N fertilizers also account for 33% of the total annual creation of Nr or 63% of all anthropogenic sources of reactive nitrogen (Nr) (Table 1). Reactive nitrogen is defined as all biologically, photochemically, and/or radiatively active forms of N -- a diverse pool of nitrogenous compounds that includes organic compounds (e.g. urea, amines, proteins, amides), mineral N forms, such as NO₃^- and NH₄⁺ as well as gases that are chemically active in …

Substrate-Mediated Gene Delivery For Assessment Of Signal Transduction Pathways In Cancer Cells, Angela K. Pannier, Zain Bengali, Eric A. Ariazi, V. Craig Jordan, Lonnie D Shea

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Gene delivery has the potential to be used in diagnostic applications, specifically to investigate cellular signal transduction pathways responsible for disease. Analysis of multiple pathways or genes in a parallel format can be achieved using a transfected cell array, a high throughput approach to correlate gene expression with functional cell responses, based on gene delivery from a substrate that supports cell adhesion. Substrate-mediated gene delivery functions by self-assembling DNA with nonviral vectors, resulting in positively charged complexes that can interact with a biomaterial or substrate. Cells cultured on the substrate are exposed to elevated DNA concentrations within the local microenvironment, …

Surface Display Of Recombinant Proteins On Bacillus Thuringiensis Spores, Cheng Du, Wing C. Chan, Timothy W. Mckeithan, Kenneth W. Nickerson

Papers in Microbiology

The insecticidal protoxin from Bacillus thuringiensis has been shown to be a major component of the spore coat. We have developed a novel surface display system using B. thuringiensis spores in which the N-terminal portion of the protoxin is replaced with a heterologous protein. The expression vector with a sporulationspecific promoter was successfully used to display green fluorescent protein and a single-chain antibody (scFv) gene that encodes anti-4-ethoxymethylene-2-phenyl-2-oxazolin-5-one (anti-phOx) antibody. The spores that carry the anti-phOx antibody can bind to phOx specifically.

Glycoprotein Gp130 Of Dictyostelium Discoideum Influences Macropinocytosis And Adhesion, Catherine P. Chia, Sujatha Gomathinayagam, Robert J. Schmaltz, Laura K. Smoyer

Department of Biochemistry: Faculty Publications

Glycoprotein gp130, found on the plasma membrane of Dictyostelium discoideum amoebae, was postulated previously to play a role in phagocytosis. The gene for gp130 was cloned and when translated, yielded a 768 amino acid preproprotein of 85.3 kDa. It had nearly 40% similarity to the 138 kDa family of glycoproteins implicated in sexual cell fusion during macrocyst formation in D. discoideum. The difference between the calculated size and observed Mr of 130 kDa on protein gels likely was due to N-glycosylation that was confirmed by lectin blots. Consistent with its surface-exposure, an antibody raised against recombinant protein stained …

Biologically Active Fluorescent Farnesol Analogs, Roman Shchepin, Razvan Dumitru, Kenneth W. Nickerson, Miranda Lund, Patrick Dussault

Patrick Dussault Publications

We describe ten polyene analogs of farnesol, typified by 3,7,11-trimethyl-2,4,6,8,10-dodecapentenaldehyde oxime, which preserve the length, cross-section, and approximate hydrophobicity of farnesol. Four of the ten display strong quorum- sensing activity in the human pathogen Candida albicans, with IC₅₀ values for inhibition of germ-tube formation as low as 10 μM. The polyenes display absorption maxima between 320 and 380 nm, with the extinction coefficients for the oximes approaching 100,000. All but two of the analogs are fluorescent, with excitation maxima varying over the range of 320–370 nm. Oxime anti-4, which can undergo fluorescence excitation at wavelengths beyond 400 …

The Ecology And Evolution Of Patience In Two New World Monkeys, Jeffrey R. Stevens, Elizabeth V. Hallinan, Marc D. Hauser

Department of Psychology: Faculty Publications

Decision making often involves choosing between small, short-term rewards and large, long-term rewards. All animals, humans included, discount future rewards—the present value of delayed rewards is viewed as less than the value of immediate rewards. Despite its ubiquity, there exists considerable but unexplained variation between species in their capacity to wait for rewards—that is, to exert patience or self-control. Using two closely related primates—common marmosets (Callithrix jacchus) and cotton-top tamarins (Saguinus oedipus)— we uncover a variable that may explain differences in how species discount future rewards. Both species faced a self-control paradigm in which individuals chose …

Establishing Native Grasses In A Big Sagebrush–Dominated Site: An Intermediate Restoration Step, Elisabeth Huber-Sannwald, David A. Pyke

United States Geological Survey: Staff Publications

Many semiarid rangelands in the Great Basin, U.S.A., are shifting dominance to woody species as a consequence of land degradation including intense livestock grazing and fire suppression. Whereas past rehabilitation efforts in Big sagebrush (Artemisia tridentata) steppes removed the shrub and added introduced forage grasses to successfully shift communities from shrublands to grasslands, current consensus is that native species should be included in restoration projects and that retention of some woody plants is desirable. We examined the potential for interseeding grasses into dense shrub communities as a precursor to thinning shrubs and releasing grasses from shrub interference. We …

Urotrema Shirleyae N. Sp. (Trematoda: Digenea: Urotrematidae) In Norops Oxylophus And N. Cupreus (Squamata: Iguania: Polychrotidae) From The Área De Conservación Guanacaste, Costa Rica, David Zamparo, Daniel R. Brooks, Vasyl Tkach

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of Urotrema inhabits Norops oxylophus and Norops cupreus from the Área de Conservación Guanacaste, Costa Rica. The new species is most similar to Urotrema scabridum but differs by having a relatively longer esophagus, at least 10% of the total body length versus 4-8% in U. scabridum; an oral sucker width:ventral sucker width ratio less than 1:1 (averaging 1:0.76) versus 1:1 or greater; an oral sucker width:pharyngeal width ratio less than 1:0.5 (averaging 1:0.42) versus greater than 1:0.5; and by having many transversely oriented posttesticular uterine loops versus a few vertically oriented posttesticular uterine loops.

Laurance Lake Temperature Model, Chris Berger, Scott A. Wells, Robert Leslie Annear

Civil and Environmental Engineering Faculty Publications and Presentations

Laurance Lake is a reservoir located in Hood River County, Oregon (Figure 1). It is located at the base on Mt. Hood in Oregon (see Figure 2 and Figure 3), discharges into the Middle Fork of the Hood River. The reservoir was constructed in 1968 for irrigation storage and has a capacity 3564 acre- feet at full pool. Since the river vio lates temperature standards, this study has been designed to construct a hydrodynamic and temperature model of Laurance reservoir in order to assess strategies for improving temperatures in the Middle Fork River.

The objectives of the study are then …

Democracy And Delinquency: An International Comparison Of Youth Violence Associated With Alternative Lifestyles, Beliefs, And Practices, Gordon A. Crews, Angela West Crews

Criminal Justice Faculty Publications

This presentation discusses youth crime and violence within the context of evolving democracy. The focus is to compare Turkish juvenile crime to that experienced in the United States and the United Kingdom (e.g., extent, characteristics, causes, solutions, etc.). During the mid-to late 1990s, Turkey’s juvenile crime rate skyrocketed, although rates have decreased in recent years. Increases seen during the 1990’s may be a natural by-product of Turkey's historical efforts to become and maintain a democratic society, and part of the price Turkey has to pay to join the European Union. Juvenile crime (and other social problems, such as suicide) may …

A Cartilage Growth Mixture Model For Infinitesimal Strains: Solutions Of Boundary-Value Problems Related To In Vitro Growth Experiments, Stephen M. Klisch, Robert L. Sah, Anne Hoger

Mechanical Engineering

A cartilage growth mixture (CGM) model is linearized for infinitesimal elastic and growth strains. Parametric studies for equilibrium and nonequilibrium boundary-value problems representing the in vitro growth of cylindrical cartilage constructs are solved. The results show that the CGM model is capable of describing the main biomechanical features of cartilage growth. The solutions to the equilibrium problems reveal that tissue composition, constituent pre-stresses, and geometry depend on collagen remodeling activity, growth symmetry, and differential growth. Also, nonhomogeneous growth leads to nonhomogeneous tissue composition and constituent pre-stresses. The solution to the nonequilibrium problem reveals that the tissue is nearly in equilibrium …

Characterization Of A Rotary Flat Tail As A Spoiler And Parametric Analysis Of Improving Directional Stability In A Portable Uav, Troy A. Leveron

Theses and Dissertations

The United States Air Force Research Lab, Munitions Directorate, Flight Vehicles, Integration Branch (AFRL/MNAV), has developed a flexible wing micro air vehicle (MAV) to be used with special tactics groups. In keeping with the requirement that this MAV be compact, previous research developed a rotatable tail mechanism which resulted in tail movement similar to that of a bird's tail. In this study the design of this tail was modified to produce a more storable vehicle. The redesign also allowed the tail to deflect upward to large angles, enabling the tail to be used as a spoiler. The aerodynamic effects of …

Evolutionary Psychology: The Emperor’S New Paradigm, David J. Buller

Faculty Articles, Papers, and Other Scholarship

For some evolutionary psychology is merely a field of inquiry, but for others it is a robust paradigm involving specific theories about the nature and evolution of the human mind. Proponents of this paradigm claim to have made several important discoveries regarding the evolved architecture of the mind. Highly publicized discoveries include a cheater-detection module, a psychological sex difference in jealousy, and motivational mechanisms underlying parental love and its lapses, which purportedly result in child maltreatment. In this article, I argue that the empirical evidence for these ‘discoveries’ is inconclusive, at best. I suggest that, as the reigning paradigm in …

Bioenergetics And Time-Motion Analysis Of Competitive Basketball, Kenji Narazaki

Student Work

Basketball has been considered to require players to employ extensive amount of energy throughout games. However, research findings regarding bioenergetic traits and demands of actual basketball performance has been considerably limited. The purpose of this study was to describe and assess bioenergetic traits of actual basketball performance in collegiate female and male players by measuring oxygen consumption (V02), heart rate (HR), blood lactate concentration (BLC), as well as rating of perceived exertion (RPE), and performing a time-motion analysis in team scrimmages. Six female and six male collegiate basketball players (20,0 ±1.2 and 20.8 ± 0.9 years old, respectively) were asked …
