Bilateral Gynandromorphy In A White-Ruffed Manakin (Corapipo Altera), Jeffrey M. Dacosta, Garth M. Spellman, John Klicka

Ornithology Program (HRC)

We report bilateral gynandromorphy in a White-ruffed Manakin (Corapipo altera) collected near Santa Fé, Panamá in 2004. The specimen had an oviduct and ovary on the left side and a single testis on the right. The plumage was phenotypically female on the right side and male on the left. The weight and genetic affinity of the specimen were characteristically female. Both Z and W chromosomes were detected in genetic samples from multiple tissue types and toe pads from both feet. This report is a novel record of gynandromorphy in a suboscine passerine.

Using Distance Sampling To Estimate Densities Of White-Tailed Deer In South-Central Minnesota, Michelle A. Larue, Clayton K. Nielsen, Marrett D. Grund

The Prairie Naturalist

Distance sampling is a method of estimating population abundance and density used by wildlife biologists for several species because of its advantages relative to other techniques. However, few wildlife biologists have used distance sampling to estimate abundance of white-tailed deer (Odocoileus virginianus). We describe a distance sampling technique used to estimate prehunt and post-hunt population densities of deer in Watonwan County, Minnesota. Estimates of white-tailed deer density were compared between distance sampling versus population modeling, and costs for distance sampling versus aerial surveys were determined. We drove 2,704 km during 24 spotlight surveys conducted from 21 October to …

Occurrences Of Small Mammal Species In A Mixedgrass Prairie In Northwestern North Dakota,, Robert K. Murphy, Richard A. Sweitzer, John D. Albertson

The Prairie Naturalist

Documentation is limited for many species of vertebrates in the northern Great Plains, particularly northwestern North Dakota (Bailey 1926, Hall 1981). Here we report relative abundances of small « 450 g) species of mammals that were captured incidental to surveys of amphibians and reptiles at Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota from 1985 to 1987 and 1999 to 2000. Our records include a modest range extension for one species. We also comment on relationships of small mammals on the refuge to vegetation changes associated with fire and grazing disturbances.

The Social Construction Of Sarbanes-Oxley, Donald C. Langevoort

Michigan Law Review

Part I will take a close look at the legitimacy of SOX by examining the two plausible stories of SOX's origins and considering the early post-SOX evidence on its costs and benefits. There is no clear-cut answer to the question of how much SOX benefits investors; both positive and critical positions are plausible. Costs have been far greater than expected, but more from SOX's implementation than from the legislative text. Before turning to how and why implementation has occurred that way-which to me is the central question of interpretation-Part II considers whether there is an alternative interpretation of SOX that …

Research, Narrative And Fiction: Conference Story, Jonathan Wyatt

The Qualitative Report

The purpose of this article is to contribute to the discussion concerning the value and validity of fiction, and arts-based approaches more broadly, as research. I offer this contribution through a narrative: Conference Story. The narrative involves its characters, in an Oxford pub, debating the merits and otherwise of Peter Clough’s (2002) book, Narratives and Fictions in Educational Research. The form, fictional narrative, performs and personifies this discussion. The article considers Clough’s purposes in undertaking and presenting his research in this form, the philosophical position(s) that underpin(s) it, the extent to which his narratives are indeed research, and how such …

Assessment Of Labview And Multisim In The Delivery Of Electronics Laboratory Content, Julio Garcia, Patricia Backer

Faculty Publications

The goal of this study, funded by the National Science Foundation, was to adapt the work of other researchers to improve the delivery of electronics lecture and laboratory content in the Electronics & Computer Technology (ECT) area. From the extensive research on ethnic and gender differences in learning styles, the evidence suggests that ethnic minorities and women work best when the material is organized so that students work in teams and have a high level of hands-on experimentation and problem-solving. We developed our materials to maximize these aspects since in our institution the “minority” constitutes the majority of our student …

Barriers To Flow: The Effects Of Experimental Cage Structures On Water Velocities In High-Energy Subtidal And Intertidal Environments, Luke P. Miller, Brian Gaylord

Faculty Publications, Biological Sciences

For decades, marine ecologists have used cages as biological enclosure or exclosure devices to manipulate movement, growth, and survival of organisms. The ability to control the densities of focal organisms makes these structures a powerful tool. However, cages can often produce artifacts that influence the outcome of experiments. Although a subset of these artifacts have been examined previously, the effects of cages on water motion have not been adequately addressed from a quantitative standpoint, especially in high-flow environments. We targeted this data gap by explicitly measuring the fractional degree of velocity reduction inside a variety of experimental cage structures across …

U.S. Environmental Policy And Politics (2000 - 2007), Emily Gornell

Honors Independent Research Papers

In the millennium, it has become increasingly apparent that a defining issue of this century will be environmental sustainability and development. With the volume of evidence and concern for global climate change over the past few decades, citizens must begin to understand that environmental policy and politics are central to any efforts that will decrease the impact and risk of this catastrophic scenario. Throughout the past seven years, the United States environmental policy has been guided by the Bush Administrations ideology. This research intends to cite the actions the Bush administration has and has not taken regarding the environment and …

Physiological Responding In A Two-Dimensional Social Interaction Simulation, Sean Brannon

Loma Linda University Electronic Theses, Dissertations & Projects

Although there were no observed effects, several suggestions were made to inform researchers in designing a study of fluid interaction. With the increasing usage of computers in the conduct of research, there is ample evidence to suggest that some emotional or physiological responses may be reliably measured using two-dimensional computer simulations.

It was predicted in accordance with the previous aggression literature that when the participant was in the role of aggressor that autonomic nervous system (ANS) responses would decrease as a function of concentration or cognitive load. It was also predicted that when the participant was in the role of …

A Qualitative Study Of Inpatient Rehabilitation Client Perceptions Of The Semi-Fixed Environment, Liane Hewitt

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose. Literature supports the importance of the environment on promoting or compromising health. However, little is known about how the semi-fixed environment affects client perceptions and recovery from a debilitating condition. The purpose of this study was to investigate beliefs about control within the semi-fixed environment and client perceptions of the rehabilitation process.

Design and Method. This study utilized a basic qualitative research design with 10 rehabilitation clients whose average inpatient length of stay was 14 days. Data were collected in two phases. Phase I included two inpatient visits involving semi-structured interviews on the rehabilitation process and …

Importance Of The Ebp (Endocarditis- And Biofilm-Associated Pilus) Locus In The Pathogenesis Of Enterococcus Faecalis Ascending Urinary Tract Infection, Kavindra V Singh, Sreedhar R Nallapareddy, Barbara E Murray

Faculty, Staff and Student Publications

BACKGROUND: We recently demonstrated that the ubiquitous Enterococcus faecalis ebp (endocarditis- and biofilm-associated pilus) operon is important for biofilm formation and experimental endocarditis. Here, we assess its role in murine urinary tract infection (UTI) by use of wild-type E. faecalis OG1RF and its nonpiliated, ebpA allelic replacement mutant (TX5475).

METHODS: OG1RF and TX5475 were administered transurethrally either at an ~1 : 1 ratio (competition assay) or individually (monoinfection). Kidney pairs and urinary bladders were cultured 48 h after infection. These strains were also tested in a peritonitis model.

RESULTS: No differences were observed in the peritonitis model. In mixed UTIs, …

Acquisition Of A Natural Resistance Gene Renders A Clinical Strain Of Methicillin-Resistant Staphylococcus Aureus Resistant To The Synthetic Antibiotic Linezolid, Seok-Ming Toh, Liqun Xiong, Cesar A Arias, Maria V Villegas, Karen Lolans, John Quinn, Alexander S Mankin

Faculty, Staff and Student Publications

Linezolid, which targets the ribosome, is a new synthetic antibiotic that is used for treatment of infections caused by Gram-positive pathogens. Clinical resistance to linezolid, so far, has been developing only slowly and has involved exclusively target site mutations. We have discovered that linezolid resistance in a methicillin-resistant Staphylococcus aureus hospital strain from Colombia is determined by the presence of the cfr gene whose product, Cfr methyltransferase, modifies adenosine at position 2503 in 23S rRNA in the large ribosomal subunit. The molecular model of the linezolid-ribosome complex reveals localization of A2503 within the drug binding site. The natural function of …

Quantitative Diffusion Tensor Imaging Detects Dopaminergic Neuronal Degeneration In A Murine Model Of Parkinson's Disease, Michael D Boska, Khader M Hasan, Danette Kibuule, Rebecca Banerjee, Erin Mcintyre, Jay A Nelson, Theresa Hahn, Howard E Gendelman, R Lee Mosley

Faculty, Staff and Student Publications

Early diagnosis of Parkinson's disease (PD) is required to improve therapeutic responses. Indeed, a clinical diagnosis of resting tremor, rigidity, movement and postural deficiencies usually reflect >50% loss of the nigrostriatal system in disease. In a step to address this, quantitative diffusion tensor magnetic resonance imaging (DTI) was used to assess nigrostriatal degeneration in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxication model of dopaminergic nigral degeneration. We now demonstrate increased average diffusion (p

Time-Kill And Synergism Studies Of Ceftobiprole Against Enterococcus Faecalis, Including Beta-Lactamase-Producing And Vancomycin-Resistant Isolates, Cesar A Arias, Kavindra V Singh, Diana Panesso, Barbara E Murray

Faculty, Staff and Student Publications

Ceftobiprole (BAL9141) is an investigational cephalosporin with broad in vitro activity against gram-positive cocci, including enterococci. Ceftobiprole MICs were determined for 93 isolates of Enterococcus faecalis (including 16 beta-lactamase [Bla] producers and 17 vancomycin-resistant isolates) by an agar dilution method following the Clinical and Laboratory Standards Institute recommendations. Ceftobiprole MICs were also determined with a high inoculum concentration (10(7) CFU/ml) for a subset of five Bla producers belonging to different previously characterized clones by a broth dilution method. Time-kill and synergism studies (with either streptomycin or gentamicin) were performed with two beta-lactamase-producing isolates (TX0630 and TX5070) and two vancomycin-resistant isolates …

Inhibition Of Enterococcus Faecium Adherence To Collagen By Antibodies Against High-Affinity Binding Subdomains Of Acm, Sreedhar R Nallapareddy, Jouko Sillanpää, Vannakambadi K Ganesh, Magnus Höök, Barbara E Murray

Faculty, Staff and Student Publications

Strains of Enterococcus faecium express a cell wall-anchored protein, Acm, which mediates adherence to collagen. Here, we (i) identify the minimal and high-affinity binding subsegments of Acm and (ii) show that anti-Acm immunoglobulin Gs (IgGs) purified against these subsegments reduced E. faecium TX2535 strain collagen adherence up to 73 and 50%, respectively, significantly more than the total IgGs against the full-length Acm A domain (28%) (P < 0.0001). Blocking Acm adherence with functional subsegment-specific antibodies raises the possibility of their use as therapeutic or prophylactic agents.

An Experimental Investigation Of Parallel Multimedia Streams Over Ieee 802.11e Wlan Networks Using Txop, Nicola Cranley, Tanmoy Debnath, Mark Davis

Conference papers

In this paper we perform an experimental investigation of the IEEE 802.11 TXOP facility to enhance the transmission of parallel multimedia streaming sessions through efficient bandwidth reservation and explicitly consider both the audio and video streams. The delay constraints associated with the audio and video streams that comprise a multimedia session pose the greatest challenge since real-time multimedia is particularly sensitive to delay as the packets require a strict bounded end-to-end delay. We show how the TXOPlimit parameter can be efficiently dimensioned to reduce the tranmission delay for the video frames. Due to tis frame-based nature, video applications are considered …

Festival Publicity Helped Change Fishing Policy., Jm Hall-Spencer

School of Biological and Marine Sciences

In the late 1990s, I saw chunks of coral reef being trawled up off the UK at a time when the fishing industry was moving into deeper waters along the European Continental Shelf edge. As a trained marine biologist I was flabbergasted, since the text books said that coral reefs were restricted to warm tropical waters. It turned out that corals were amongst the first life forms discovered during pioneering deep-sea surveys off southwest Ireland in 1869. In fact, at least as many coral species are described from the deep sea as from shallow waters and large, reef-forming corals have …

Intelligence Through Interaction: Towards A Unified Theory For Learning, Ah-Hwee Tan, Gail A. Carpenter, Stephen Grossberg

Research Collection School Of Computing and Information Systems

Machine learning, a cornerstone of intelligent systems, has typically been studied in the context of specific tasks, including clustering (unsupervised learning), classification (supervised learning), and control (reinforcement learning). This paper presents a learning architecture within which a universal adaptation mechanism unifies a rich set of traditionally distinct learning paradigms, including learning by matching, learning by association, learning by instruction, and learning by reinforcement. In accordance with the notion of embodied intelligence, such a learning theory provides a computational account of how an autonomous agent may acquire the knowledge of its environment in a real-time, incremental, and continuous manner. Through a …

Plant Growth-Promoting Rhizobacteria Do Not Pose Any Deleterious Effect On Cowpea And Detectable Amounts Of Ethylene Are Produced, Olubukola O. Babalola, Abiodun I. Sanni, George D. Odhiambo, Baldwyn Torto

All Peer-Reviewed Publications

The use of trap crops such as cowpea could reduce the effects of the root parasitic weed, Striga hermonthica and its subsequent constraints on the growth of cereals. Certain bacteria could augment the trap crop stimulatory effect. We studied the effect of three bacteria introduced to the rhizosphere of three cowpea varieties at planting. Number of days to cowpea flowering was noted and at harvest, data were collected on pod characteristics and biomass. Means of data subjected to ANOVA were compared using Tukey's Studentized Range Test. We analysed bacterial headspace volatiles for ethylene by gas chromatography and gas chromatography-mass spectrometry. …
