Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

Faculty Scholarship

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.

At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic …

Sport And Society, Robert Washington, David Karen

Sociology Faculty Research and Scholarship

Despite its economic and cultural centrality, sport is a relatively neglected and undertheorized area of sociological research. In this review, we examine sports' articulation with stratification issues, especially race, class, and gender. In addition, we look at how the media and processes of globalization have affected sports.We suggest that sports and cultural sociologists need to attend more closely to how leisure products and practices are produced and distributed and how they intersect with educational, political, and cultural institutions. We propose the work of Bourdieu andthe new institutionalism to undergird future research.

The Impact Of Unmediated Document Delivery On Faculty Use Of Traditional Interlibrary Loan At Wichita State University, Kathy A. Downes, Ted Naylor

University of Nebraska-Lincoln Libraries: Faculty Publications

In these times of growing journal prices and shrinking budgets, alternative methods of information access are a necessity. Document delivery services have become an important alternative to providing information access beyond traditional interlibrary loan services. This article analyzes the effect the "unmediated" EbscoDoc document delivery service had on traditional interlibrary loan in a medium sized academic library. Access to the service was provided to faculty members at Wichita State University for a period of approximately two years. Use of the service varied from faculty members who ordered one article to the "super" users who ordered from 100 to 400 documents. …

Technology As The Representative Anecdote In Popular Discourses Of Health And Medicine, Lynn M. Harter, Phyllis Japp

Department of Communication Studies: Faculty Publications

Using a Burkean framework (1969), this article approaches medical dramas as cultural texts to be read for dominant meanings of health and health care. Burke’s representative anecdote illuminates the melding of science, technology, and healing in popular discourses of health, establishing technological intervention as the norm and marginalizing nontechnological (i.e., alternative) forms of health care. Popular entertainment reinforces this anecdote in narratives of healing as technological competence triumphing over nature.

Finding The Meanings Of College Drinking: An Analysis Of Fraternity Drinking Stories, Thomas Workman

Department of Communication Studies: Faculty Publications

College drinking has traditionally been studied from a public health perspective that attempts to quantify behavior as a means toward description, explanation, and intervention. This article offers a critical and cultural approach to understanding the meanings and functions of high-risk drinking and the ways in which those meanings are reproduced within the culture. Data were collected via an ethnographic study of fraternity members at a large midwestern university to explore the communication of excessive drinking norms. Viewed from various narrative and structural theories, the study examines collected drinking stories as a source for analyzing the construction of meanings surrounding drunkenness …

United States Army Corps of Engineers, Omaha District

The Endangered Species Act (ESA) requires that the Corps of Engineers (Corps), in coordination with the appropriate resources agency, will ensure that any action authorized, funded, or carried out is not likely to jeopardize the continued existence of any federally listed threatened or endangered species or result in the destruction or adverse modification of critical habitat. Formal consultation between the U.S. Fish and Wildlife Service (FWS) and the Corps under Section 7 of the ESA culminated with the "Biological Opinion on the Operation of the Missouri River Main Stem System, Operation and Maintenance of the Missouri River Bank Stabilization and …

Fungal Symbiosis From Mutualism To Parasitism: Who Controls The Outcome, Host Or Invader?, Regina S. Redman, David Dunigan, Rusty J. Rodriguez

Department of Plant Pathology: Faculty Publications

• Plant symbiotic fungi are generally thought to express a single lifestyle that might increase (mutualism), decrease (parasitism), or have no influence (commensalism) on host fitness. However, data are presented here demonstrating that plant pathogenic Colletotrichum species are able to asymptomatically colonize plants and express nonpathogenic lifestyles.

• Experiments were conducted in growth chambers and plant colonization was assessed by emergence of fungi from surface sterilized plant tissues. Expression of symbiotic lifestyles was assessed by monitoring the ability of fungi to confer disease resistance, drought tolerance and growth enhancement.

• Several pathogenic Colletotrichum species expressed either mutualistic or commensal lifestyles …

The Aspergillus Nidulans Snt Genes Are Required For The Regulation Of Septum Formation And Cell Cycle Checkpoints, Peter R. Kraus, Steven D. Harris

Department of Plant Pathology: Faculty Publications

In Aspergillus nidulans, germinating conidia undergo multiple rounds of nuclear division before forming a septum. Previous genetic results suggest that the ability to separate nuclear division and septum formation depends upon a threshold level of activity of the cyclin-dependent kinase NIMXcdk1. Mutations in nimX and nimT, the gene encoding the NIMXcdk1-activating phosphatase, have revealed that Tyr-15 phosphorylation is important for determining the timing of the formation of the first septum. Here, we describe a screen for suppressors of nimT23 (snt), designed to identify additional components of the pathway regulating septum formation. We show that a subset …

Occurrence Of Cyanazine Compounds In Groundwater: Degradates More Prevalent Than The Parent Compound, Dana Kolpin, E. Michael Thurman, S. Michael Linhart

United States Geological Survey: Staff Publications

A recently developed analytical method using liquid chromatography/mass spectrometry was used to investigate the occurrence of cyanazine and its degradates cyanazine acid (CAC), cyanazine amide (CAM), deethylcyanazine (DEC), and deethylcyanazine acid (DCAC) in groundwater. This research represents some of the earliest data on the occurrence of cyanazine degradates in groundwater. Although cyanazine was infrequently detected in the 64 wells across Iowa sampled in 1999, cyanazine degradates were commonly found during this study. The most frequently detected cyanazine compound was DCAC (32.8%) followed by CAC (29.7%), CAM (17.2%), DEC (3.1%), and cyanazine (3.1%). The frequency of detection for cyanazine or one …

United States Department of Agriculture Wildlife Services: Staff Publications

The Brucella abortus vaccine strain RB51 (SRB51) is being considered for use in the management of brucellosis in wild bison (Bison bison) and elk (Cervus elaphus) populations in the Greater Yellowstone Area (USA). Evaluation of the vaccine’s safety in non-target species was considered necessary prior to field use. Between June 1998 and December 1999, ground squirrels (Spermophilus richardsonii, n=21), deer mice (Peromyscus maniculatus, n=14), prairie voles (Microtus ochrogaster, n=21), and ravens (Corvus corax, n=13) were orally inoculated with SRB51 or physiologic saline. Oral and …

Serological Responses Of Coyotes To Two Commercial Rabies Vaccines, Frederick F. Knowlton, Marianna Roetto, Deborah Briggs

United States Department of Agriculture Wildlife Services: Staff Publications

Between August 1993 and September 1994 we documented serological responses of coyotes (Canis latrans) vaccinated with two commercial rabies vaccines licensed for use in domestic dogs. Serologic responses were documented by testing for rabies virus neutralizing antibodies with the rapid fluorescent focus inhibition test (RFFIT) at 30, 90, 180, 270, and 365 days post-vaccination. All coyotes vaccinated with Imrab 3^® (Rhone-Merieux, Inc.), and 75% of those vaccinated with Dura-Rab 3^® (Immunovet, Inc.) seroconverted, as evidenced by the presence of antirabies antibody titers ≥1:5 in one or more of the five post-vaccination samples. The percent of coyotes …

Application Of Fuzzy Logic In Automated Cow Status Monitoring, R. M. De Mol, Wayne Woldt

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Sensors that measure yield, temperature, electrical conductivity of milk, and animal activity can be used for automated cow status monitoring. The occurrence of false-positive alerts, generated by a detection model, creates problems in practice. We used fuzzy logic to classify mastitis and estrus alerts; our objective was to reduce the number of false-positive alerts and not to change the level of detected cases of mastitis and estrus. Inputs for the fuzzy logic model were alerts from the detection model and additional information, such as the reproductive status. The output was a classification, true or false, of each alert. Only alerts …

The Wasp-Like Protein Scar Regulates Macropinocytosis, Phagocytosis And Endosomal Membrane Flow In Dictyostelium, David J. Seastone, Ed Harris, Lesly A. Temesvari, James E. Bear, Charles L. Saxe, James Cardelli

Department of Biochemistry: Faculty Publications

Scar, a member of the WASp protein family, was discovered in Dictyostelium discoideum during a genetic screen for second-site mutations that suppressed a developmental defect. Disruption of the scar gene reduced the levels of cellular F-actin by 50%. To investigate the role of Scar in endocytosis, phagocytosis and endocytic membrane trafficking, processes that depend on actin polymerization, we have analyzed a Dictyostelium cell line that is genetically null for Scar. Rates of fluid phase macropinocytosis and phagocytosis are significantly reduced in the scar^- cell-line. In addition, exocytosis of fluid phase is delayed in these cells and movement of fluid …

Rab11-Like Gtpase Associates With And Regulates The Structure And Function Of The Contractile Vacuole System In Dictyostelium, Ed Harris, Kunito Yoshida, James Cardelli, John Bush

Department of Biochemistry: Faculty Publications

Screening of a cDNA library revealed the existence of a Dictyostelium cDNA encoding a protein 80% identical at the amino acid level to mammalian Rab11. Subcellular fractionation and immunofluorescence studies revealed that DdRab11 was exclusively associated with the ATPase proton pump-rich contractile vacuole membrane system, consisting of a reticular network and bladder-like vacuoles. Video microscopy of cells expressing GFP-DdRab11 revealed that this Rab was associated with contractile vacuolar bladders undergoing formation, fusion and expulsion of water. The association of DdRab11 with contractile vacuole membranes was disrupted when cells were exposed to either hypo-osmotic conditions or an inhibitor of the ATPase …

Selenoprotein Oxidoreductase With Specificity For Thioredoxin And Glutathione Systems, Qi-An Sun, Leo Kirnarsky, Simon Sherman, Vadim N. Gladyshev

Department of Biochemistry: Faculty Publications

Thioredoxin (Trx) and glutathione (GSH) systems are considered to be two major redox systems in animal cells. They are reduced by NADPH via Trx reductase (TR) or oxidized GSH (GSSG) reductase and further supply electrons for deoxyribonucleotide synthesis, antioxidant defense, and redox regulation of signal transduction, transcription, cell growth, and apoptosis. We cloned and characterized a pyridine nucleotide disulfide oxidoreductase, Trx and GSSG reductase (TGR), that exhibits specificity for both redox systems. This enzyme contains a selenocysteine residue encoded by the TGA codon. TGR can reduce Trx, GSSG, and a GSH-linked disulfide in in vitro assays. This unusual substrate specificity …

A New Lungworm In Muskoxen: An Exploration In Arctic Parasitology, Susan J. Kutz, Eric P. Hoberg, Lydden Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Ruminants are vital elements of the Holarctic ecosystem. Little is known, however, of the structure or biology of their parasite fauna, particularly in North America. Global warming, coupied with increasing human activity in the Arctic, requires enhanced intemational interdisciplinary efforts to better understand the many factors, including parasites, that influence the population health of caribou, reindeer, muskoxen and wild sheep. The discovery of an unusual new genus of protostrongylid lung nematode in muskoxen from the central Canadian Arctic is described, and the intricacies of the parasite's relationship with its muskoxen definitive hosts, its gastropod intermediate hosts and the arctic environment …

Are Saudi Arabian Hospitals Prepared For The Threat Of Biological Weapons?, Manuel W. Mah, Ziad A. Memish

Saudi Medical Journal

The use of biological weapons has been recorded repeatedly in history. Until recently, biological terrorism had been little discussed or written about. However, events over the past 12 to 18 months have made it clear that likely perpetrators already envisage every possible scenario. Nations and dissident groups exist that have both the motivation and access to utilize biological weapons. In April 1994, a Russian biological weapons expert presented the conclusions of the Russian experts as to the agents most likely to be used: smallpox, anthrax, and plague. Health care workers in the Kingdom of Saudi Arabia (physicians, nurses, and emergency …
