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. …

Pulmonary Lymphangioleiomyomatosis, Hilal B. Shawki, Shakir M. Muhammed, Amal N. Reda, Thair S. Abdulla, Delaram M. Ardalan

Saudi Medical Journal

A 38-year-old Iraqi female, presented with one-year history of exertional dyspnea and exercise intolerance, without systemic or constitutional symptoms. Clinical examination revealed bilateral basal crackles with signs suggestive of left side pleural effusion, chest x-ray showed left sided pleural effusion, and diffuse bilateral basal pulmonary shadowing. Her biochemical analysis, hematological tests, electrocardiogram and echocardiography were normal, aspiration of the fluid revealed a chylothorax, the radiological shadowing was proved by computed tomography scan of the chest to be diffuse cystic lesions involving mostly the lower lobes. Open lung biopsy showed dilated lymphatic vessels with surrounding inflammatory cells and smooth muscle fibers …

Placenta Percreta With Bladder Invasion. A Plea For Multidisciplinary Approach, Fahmy M.I. Shawish, Fayez T. Hammad, Essa M. Kazim

Saudi Medical Journal

Placenta previa percreta with the urinary bladder invasion is a rare but potentially lethal condition. It has an increasing clinical significance due to its association with previous cesarean sections and uterine curettage. Herein, we report on a patient with placenta percreta and bladder invasion, who presented with hematuria and in whom delivery was delayed to almost full term highlighting the potential catastrophic results and the need for a multidisciplinary approach with the need to involve surgeons who are familiar with vascular and urologic surgery. We also present an elegant MRI of placenta percreta invading the urinary bladder, which shows that …

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 …

Personal, Interpersonal, And Political Temperaments, John Alford, John R. Hibbing

Department of Political Science: Faculty Publications

Are political liberals generous? Are political conservatives conscientious? Are generous people personally agreeable? Research in behavioral genetics and elsewhere increasingly indicates a biological basis for the manner in which people behave in personal, interpersonal, and political situations, but this biological basis does not mean behavior in these three very different contexts is correlated. In this article, using an original data set obtained from nearly three hundred subjects, the authors are able to test for the degree to which personal, interpersonal, and political temperaments are related. As expected, the overall correlations are quite low. Standard personality traits do not predict political …

The Biology Of Political Behavior: An Introduction, John R. Hibbing, Kevin B. Smith

Department of Political Science: Faculty Publications

A broad cross-section of the social sciences is increasingly turning to biology and evolutionary theory to help explain human behavior. Political science is a notable exception to this trend, even though there are sound conceptual reasons for expecting biological processes to play an important role in explaining political behavior. While agreeing with the conceptual arguments, the authors believe original empirical research is the most persuasive means of convincing political science to incorporate biology in explanations of political behavior. Techniques developed in neuroscience, behavioral genetics, agent-based simulation, experimental economics, and other fields offer exciting research opportunities to explore questions of central …

Regional Advocacy Networks And The Protocol On The Rights Of Women In Africa, Melinda Adams, Alice J. Kang

Department of Political Science: Faculty Publications

While there has been a significant amount of research on transnational feminist activism at the global level, many feminist transnational advocacy networks are mobilizing within world regions. The lack of attention to the regional level has created a considerable imbalance in research on transnational activism. This article's first objective is to define regional advocacy networks (RANs) as a collection of individuals and organizations from the same world region working together toward a common goal. The article's second objective is to explore the conditions under which RANs are influential. We investigate conditions for RAN success through a case study of an …

The Role Of Drinking Motives In Social Anxiety And Alcohol Use, Lindsay S. Ham, Michel Bonin, Debra A. Hope

Department of Psychology: Faculty Publications

Although social anxiety and problem drinking commonly co-occur, the relationship between social anxiety and drinking among college students is not well understood. The current study examined the relationship between drinking motives, or reasons for drinking, and social anxiety in 239 volunteers. Contrary to hypotheses, high (n = 83), moderate (n = 90), and low (n = 66) social anxiety groups did not differ in endorsement of coping and conformity drinking motives. Further, social anxiety was negatively related to weekly alcohol use and unrelated to alcohol-related problems. Post hoc hierarchical multiple regression analyses conducted for each social anxiety …

Factors Influencing Ground-Water Recharge In The Eastern United States, Bernard T. Nolan, Richard W. Healy, Patrick E. Taber, Kimberlie Perkins, Kerie J. Hitt, David M. Wolock

United States Geological Survey: Staff Publications

Ground-water recharge estimates for selected locations in the eastern half of the United States were obtained by Darcian and chloride-tracer methods and compared using statistical analyses. Recharge estimates derived from unsaturated-zone (R_UZC) and saturated-zone (R_SZC) chloride mass balance methods are less variable (interquartile ranges or IQRs are 9.5 and 16.1 cm/yr, respectively) and more strongly correlated with climatic, hydrologic, land use, and sediment variables than Darcian estimates (IQR = 22.8 cm/yr). The unit-gradient Darcian estimates are a nonlinear function of moisture content and also reflect the uncertainty of pedotransfer functions used to estimate hydraulic parameters. Significance …

New Insights Into Marine Migration And Winter Habitat Of Gulf Sturgeon, Randy E. Edwards, Frank M. Parauka, Kenneth J. Sulak

United States Geological Survey: Staff Publications

Migrations and movements of Gulf sturgeon Acipenser oxyrinchus desotoi were determined using satellite pop-up archival transmitting (PAT) tags and acoustic telemetry. Adult Gulf sturgeon from four rivers in northwestern Florida were caught with gill nets and were tagged with PAT and acoustic tags in the fall of 2001 and 2002. PAT tags were programmed to release in early February 2002 and 2003 to provide information about location of late-winter marine habitats. However, only 5 of 25 provided meaningful location information. Three of the PAT-tagged fish were relocated acoustically near the PAT tag pop-up locations, one of which was in Choctawhatchee …

The topic to be investigated in this thesis is the impact of the United States Environmental Protection Agency (U.S. EPA) Colleges and Universities Sector Program on three universities located in New York State. The parameters to be analyzed are the changes in the way environmental issues have been approached using tools and incentives provided by the EPA Colleges and Universities Sector Program, drivers that motivate the colleges to achieve environmental management through compliance with environmental laws and regulations, and obstacles that stand in the way of compliance. This research is based primarily on a survey conducted in three universities participating …

Does The Observer Have An Effect?: An Analysis Of The Use Of The Dialogue Metaphor In Canada's Courts, Richard Haigh, Michael Sobkin

Osgoode Hall Law Journal

In "Charter Dialogue Revisited-Or 'Much Ado About Metaphors,"' it is noted that the original idea behind the dialogue metaphor was simply to describe Canada's constitutional structure. Despite this, the metaphor has been criticized for having normative content and influencing courts and legislatures. In this commentary, the authors analyze all Supreme Court of Canada and lower court uses of the dialogue metaphor and conclude that, with some exceptions, the courts have employed the metaphor properly, i.e., descriptively. Since, however, the metaphor can be misapplied-used other than to describe or explain the relationship between the courts and legislatures in Canada-the authors recommend …

Atmospheric Mercury Over The Ne Pacific During Spring 2002: Gradients, Residence Time, Upper Troposphere Lower Stratosphere Loss, And Long‐Range Transport, L. F. Radke, H. R. Friedli, Brian G. Heikes

Graduate School of Oceanography Faculty Publications

Gaseous elemental mercury (GEM) was measured over the North Pacific and coastal California, Oregon and Washington in spring 2002 during the Intercontinental Transport and Chemical Transformation Experiment–2002 (ITCT2K2). Observations were made from the NOAA WP3 on 11 flights which spanned an altitude range of 0–8 km and latitudes between 35 and 55°N. GEM was determined using a Tekran 2537A mercury instrument modified for airborne use to collect and analyze samples every 2.5 min under variable ambient temperature and pressure conditions. GEM concentrations were in general at the low end of previous measurements made over continents and in fresh continental outflow …

Validation Of Aura Microwave Limb Sounder Ozone By Ozonesonde And Lidar Measurements, Y. B. Jiang, J. Merrill, Et Al

Graduate School of Oceanography Faculty Publications

We present validation studies of MLS version 2.2 upper tropospheric and stratospheric ozone profiles using ozonesonde and lidar data as well as climatological data. Ozone measurements from over 60 ozonesonde stations worldwide and three lidar stations are compared with coincident MLS data. The MLS ozone stratospheric data between 150 and 3 hPa agree well with ozonesonde measurements, within 8% for the global average. MLS values at 215 hPa are biased high compared to ozonesondes by ∼20% at middle to high latitude, although there is a lot of variability in this altitude region. Comparisons between MLS and ground‐based lidar measurements from …

Periodically Collapsing Bubbles In The Asian Emerging Stock Markets, Ako Doffou

WCBT Faculty Publications

This paper investigates empirically the existence of periodically collapsing bubbles in the Asian emerging stock markets using the Enders-Siklos (2001) momentum threshold autoregressive model. As explained in Bohl (2003), this non-linear time series technique can be used to analyze bubble driven run-ups in stock prices followed by a crash in a non- cointegration framework with asymmetric adjustment. This technique offers a more potent insight in the stock prices behavior than can possibly be obtained using conventional non-cointegration tests. The empirical findings for ten Asian emerging stock markets from 1993 to 2005 refute the bubble hypothesis.

Is Support For Top Managers' Dynamic Capabilities, Environmental Dynamism, And Firm Performance: An Empirical Investigation, Michael J. Zhang

WCBT Faculty Publications

Despite a continual interest in developing information systems (IS) to support the work of top managers, assessing the impact of IS support for top managers and their capabilities on the bottom-line performance of firms has received little attention in existing literature. Drawing upon the resource based view of competitive advantage, this paper argues that firms that provide IS support for their top managers’ dynamic capabilities may enjoy competitive advantage and superior firm performance. The performance impact of IS support for two key dynamic capabilities of top managers (fast response and mental model building) under different (dynamic vs. stable) external environments …

Monetary And Fiscal Policy In Poland During The Eu Accession, Lucjan Orlowski

WCBT Faculty Publications

The main objective of this chapter is to review the fiscal and monetary policies of Poland for EU accession and to extract their guiding precepts. Only the most essential aspects of fiscal and monetary convergence are examined, with some attention to institutional convergence. An in-depth analysis of institutional convergence falls beyond the boundaries of this study, as its main focus is on the systemic foundations of macroeconomic stabilization policies during the economic transition and in the course of preparations for EU accession. The chapter also examines policy options for the post-accession macroeconomic policy strategy which will focus on preparations for …
