The Activist Wpa: Changing Stories About Writing And Writers, Linda Adler-Kassner

All USU Press Publications

One wonders if there is any academic field that doesn't suffer from the way it is portrayed by the media, by politicians, by pundits and other publics. How well scholars in a discipline articulate their own definition can influence not only issues of image but the very success of the discipline in serving students and its other constituencies. The Activist WPA is an effort to address this range of issues for the field of English composition in the aftermath of No Child Left Behind and the Spellings Commission. Drawing on recent developments in framing theory and the resurgent traditions of …

The Ecology Of Fear: Colonization And Oviposition In Aquatic Systems [Poster], Leeanna Pletcher, Johanna Kraus, James R. Vonesh

Biology Presentations

Introduction

Amphibians and aquatic invertebrates have complex life histories that link aquatic and terrestrial food webs. It has been suggested that amphibian reproduction is an important source of carbon to some aquatic systems. Movement of organisms across the aquatic-terrestrial habitat boundary can represent important subsidies to the receiving habitat. Subsidies are organisms, nutrients, or detritus that cross habitat boundaries and are consumed, and these allochthonous inputs can affect food web structure. Predators can alter subsidies by consuming organisms that would otherwise move across habitat boundaries. Predator induced shifts in habitat selection are a well known non-lethal effect in aquatic systems. …

Mitochondria In Energy-Limited States: Mechanisms That Blunt The Signaling Of Cell Death, Steven C. Hand, Michael A. Menze

Faculty Research & Creative Activity

Cellular conditions experienced during energy-limited states – elevated calcium, shifts in cellular adenylate status, compromised mitochondrial membrane potential – are precisely those that trigger, at least in mammals, the mitochondrion to initiate opening of the permeability transition pore, to assemble additional protein release channels, and to release pro-apoptotic factors. These proapototic factors in turn activate initiator and executer caspases. How is activation of mitochondria-based pathways for the signaling of apoptotic and necrotic cell death avoided under conditions of hypoxia, anoxia, diapause, estivation and anhydrobiosis? Functional trade-offs in environmental tolerance may have occurred in parallel with the evolution of diversified pathways …

Clapper Rails As Indicators Of Mercury And Pcb Bioavailability In A Georgia Saltmarsh System, James C. Cumbee Jr., Karen F. Gaines, Gary L. Mills, N. Garvin, Warren L. Stephens Jr., James N. Novak, I. L. Brisbin Jr.

Faculty Research & Creative Activity

Clapper rails (Rallus longirostris) were used as an indicator species of estuarine marsh habitat quality because of their strong site fidelity and predictable diet consisting of mostly benthic organisms. Mercury (Hg) and the polychlorinated biphenyl (PCB) Aroclor 1268 concentrations were determined for sediments, crabs, as well as clapper rail adults and chicks collected from salt marshes associated with the LCP Superfund site in Brunswick, Georgia. Home ranges were established for adult rails, and sediment and crab samples were taken from each individual’s range. The study was designed to minimize the spatial variability associated with trophic transfer studies by choosing an …

Exposure And Exposure Modeling, Karen F. Gaines, T. E. Chow, S. A. Dyer

Faculty Research & Creative Activity

Exposure to contaminants in the environment is quantified through the ecological risk assessment (ERA) process which provides a framework for the development and implementation of environmental management decisions. The ERA uses available toxicological and ecological information to estimate the probability of occurrence for a specified undesired ecological event or endpoint. The level for these endpoints depends on the objectives and the constraints imposed upon the risk assessment process; therefore, multiple endpoints at different scales may be necessary. ERAs Ecotoxicology | Exposure and Exposure Assessment 1527Author's personal copy often rely on the link between these undesired endpoints to a threshold of …

Environmental Conditions Affect Sperm Competition Risk In Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Carissa A. Schoenick, Patrick C. Enstrom

Faculty Research & Creative Activity

Males of many species guard their mates to prevent rivals from usurping paternity of the potential offspring. Environmental conditions, such as temperature, may affect a male’s ability to guard a female effectively and consequently the amount of sperm competition that occurs. We tested whether temperature and light affected mating behavior in laboratory experiments on the Japanese beetle, Popillia japonica Newman, a species in which males guard females for minutes to many hours after mating. When tested in groups, under conditions of high temperature and high light, males guarded females for shorter periods of time and males and females both mated …

Spatial And Temporal Expression Profiling Of Cell-Wall Invertase Genes During Early Development In Hybrid Poplar, Thomas Canam, Sarah Mak, Shawn Mansfield

Faculty Research & Creative Activity

Cell-wall invertase genes are spatially and temporally regulated in several plant species, including Daucus carota L., Lycopersicon esculentum L. and Solanum tuberosum L. However, few studies of cell-wall invertase genes of trees have been conducted, despite the importance of trees as a source of lignocellulosic biopolymers.We identified three putative cell-wall invertase genes in hybrid poplar (Populus alba L. × grandidentata Michx.) that showed higher homology to each other than to cell-wall invertases of other dicotyledonous species, with two of the genes (Pa×gINV2 and Pa×gINV3) appearing as a genomic tandem repeat. These genes are more similar to each other than to …

Vegetative Anatomy Of Calypsoeae (Orchidaceae), William Stern, Barbara Carlsward

Faculty Research & Creative Activity

Calypsoeae represent a small tribe of anatomically little-known orchids with a wide distribution in the Western Hemisphere. Leaves are present in all genera, except Corallorhiza and Wullschlaegelia both of which are subterranean taxa. Stomata are abaxial (ad- and abaxial in Aplectrum) and tetracytic (anomocytic in Calypso). Fiber bundles are absent in leaves of all taxa examined except Govenia tingens. Stegmata are present in leaves of only Cremastra and Govenia. Roots are velamentous, except in filiform roots of Wullschlaegelia. Vegetative anatomy supports a relationship between Wullschlaegelia and Corallorhiza but does not support the grouping of winter-leaved Aplectrum and Tipularia nor proposed …

Old Acetogens, New Light, Steven Daniel, Harold Drake, Anita Gößner

Faculty Research & Creative Activity

Acetogens utilize the acetyl-CoA Wood-Ljungdahl pathway as a terminal electron-accepting, energy-conserving, CO2-fixing process. The decades of research to resolve the enzymology of this pathway (1) preceded studies demonstrating that acetogens not only harbor a novel CO2-fixing pathway, but are also ecologically important, and (2) overshadowed the novel microbiological discoveries of acetogens and acetogenesis. The first acetogen to be isolated, Clostridium aceticum, was reported by Klaas Tammo Wieringa in 1936, but was subsequently lost. The second acetogen to be isolated, Clostridium thermoaceticum, was isolated by Francis Ephraim Fontaine and co-workers in 1942. C. thermoaceticum became the most extensively studied acetogen and …

Simulating The Effects Of Wetland Loss And Inter-Annual Variability On The Fitness Of Migratory Bird Species, Jill Deppe, James Smith

Faculty Research & Creative Activity

Long-distance migratory shorebirds require wetland stopover sites where they can forage and deposit sufficient fat to complete their migration and, in the spring, reproduce. Conservation biologists are concerned that continental-scale reductions in wetland availability and quality due to human disturbance, climate change, and natural drought events are negatively impacting these species by eliminating critical stopovers along migratory flyways. We describe an individual-based migration model driven by remotely sensed land surface data, climate data assimilation models, and biological field data to examine the impact of changing environmental conditions on migration routes, temporal patterns, and fitness. We used an evolutionary programming approach …

Delegation Success And Policy Failure: Collective Delegation And The Search For Iraqi Weapons Of Mass Destruction, Michael J. Tierney

Law and Contemporary Problems

Tierney argues that international delegation can have important consequences, even for powerful states. In particular, he contends that the US delegation of inspection authority to United Nations weapons inspectors and to the International Atomic Energy Association after the Gulf War of 1990-91 entailed significant sovereignty costs by affecting the timing and costliness of the subsequent 2003 US invasion of Iraq. Among other things, he notes that the inspectors' independent behavior made it much more difficult for the US to assemble the type of multilateral coalition that would share the costs as it had in the earlier Gulf War. Tierney also …

The Annotation Of Traditional Irish Dance Music Using Matt2 And Tansey, Bryan Duggan, Brendan O'Shea, Mikel Gainza, Padraig Cunningham

Conference papers

Current estimates put the canon of traditional Irish dance tunes at least 7,000 compositions. Given this diversity, a common problem faced by musicians and ethnomusicologists is identifying tunes from recordings. This is evident even in the number of commercial recordings whose title is gan aimn (without name). This work attempts to solve this problem by developing a Content Based Music Information Retrieval (CBMIR) System adapted to the characteristics of traditional Irish music. A system is presented called MATT2 (Machine Annotation of Traditional Tunes) whose primary goal is to annotate recordings of traditional Irish dance music with useful meta-data including tune …

Ward, Chesca Choi, Jean-Leonard Kagabo, Michael Sauer, Tara Kuipers, Timothy Hotchkiss Timothy Hotchkiss, Nate Banner, Renee A. Chellson, Theresa Ohaeri, Langston Gant, Leah Vanderhill

Articles

During the course of a day human skin is exposed to solar UV radiation that fluctuates in fluence rate within the UVA (290-315 nm) and UVB (315-400 nm) spectrum. Variables affecting the fluence rate reaching skin cells include differences in UVA and UVB penetrating ability, presence or absence of sunscreens, atmospheric conditions, and season and geographical location where the exposure occurs. Our study determined the effect of UVA fluence rate in solar-simulated (SSR) and tanning-bed radiation (TBR) on four indicators of oxidative stress---protein oxidation, glutathione, heme oxygenase-1, and reactive oxygen species--in human dermal fibroblasts after receiving equivalent UVA and UVB …

Experimental And Numerical Investigation Of Wire Waveguides For Therapeutic Ultrasound Angioplasty, Declan Noone (Thesis)

Other resources

Therapeutic ultrasound angioplasty is an emerging minimally invasive cardiovascular procedure for disrupting atherosclerotic lesions using small diameter wire waveguides. The lesions are damaged through a combination of direct ablation, pressure waves, cavitation and acoustic streaming caused by distal-tip displacements at ultrasonic frequencies. Numerical and experimental methods are used to investigate the outputs of the wire waveguides during ultrasonic activation. A commercially available generator and acoustic horn are used in combination with Nickel-Titanium (NiTi) wire waveguides in this study. A laser sensor is used to measure the frequency and amplitude output of the distal tip of the wire waveguide, and this …

Evaluation Of In Vitro Virulence Characteristics Of The Genus Pandoraea In Lung Epithelial Cells, Emma M. Caraher, Jonathan Collins, Jonathan Collins,, Gillian Herbert, Philip G. Murphy Philip G. Murphy, Charles G. Gallagher, Mary J. Crowe, Máire Callaghan, Siobhan Mcclean

Articles

Pandoraea species are emerging opportunistic pathogens capable of causing chronic lung infections in cystic fibrosis patients. This study examined the interactions of 17 Pandoraea isolates from the five identified species (Pandoraea apista, Pandoraea norimbergensis, Pandoraea pulmonicula, Pandoraea sputorum and Pandoraea pnomenusa) plus two Pandoraea genomospecies isolates with lung epithelial cells and their ability to form biofilms in vitro. Only three isolates showed an ability to invade A549 lung epithelial cells, and only one isolate was able to form biofilms. In contrast, all isolates triggered a pronounced pro-inflammatory response, with elevation of both interleukin (IL)-6 (two- to 19-fold) and IL-8 (10- …

Scale-Dependent Habitat Use By Fall Migratory Birds: Vegetation Architecture, Floristics, And Geographic Consistency, Jill L. Deppe, John T. Rotenberry

Faculty Research & Creative Activity

Animal habitat selection is a central focus of ecology and conservation biology. Understanding habitat associations in migratory animals is particularly complicated because individuals have variable habitat requirements during the annual cycle, across their geographic range, along migratory routes, and at multiple spatial scales. We studied habitat associations of 16 fall Nearctic–Neotropical migratory land birds at two spatial scales at a stopover site along the northern Yucatan coast to examine scale-dependent habitat use, identify proximate cues shaping birds' distributions, and evaluate similarities in habitat use between our tropical stopover site and temperate sites. We addressed scale-dependent habitat associations in two ways, …

Eloquent Witness: Nibley On Himself, Others, And The Temple, Hugh Nibley

Maxwell Institute Publications

One of the stunning aspects of Dr. Hugh Nibley's genius was his persistent sense of wonder. That trait induced him to range widely through very disparate subjects of study- all covered in volume 17 of The Collected Works of Hugh Nibley on Himself, Others, and the Temple. In this compilation of materials, most of which have been published previously outside the Collected Works volumes, Nibley explores the ancient Egyptians, the temple, the life sciences, world literature, ancient Judaism, and Joseph Smith and the Restoration. The contents of this volume illustrate the breadth of his interest through autobiographical sketches, interviews, book …

The high stocking density, stress, unhygienic conditions, lack of sunlight, and breeding practices typical of industrial poultry and egg production systems may facilitate the emergence and spread of diseases, including highly pathogenic avian influenza viruses with public health implications such as H5N1.

An Hsus Report: Food Safety Concerns With The Slaughter Of Downed Cattle, The Humane Society Of The United States

Impact of Animal Agriculture

Nonambulatory cattle may be at higher risk of harboring foodborne pathogens such as E. coli O157:H7, Salmonella, and, very rarely, the infectious agent that causes bovine spongiform encephalopathy, colloquially known as “mad cow disease.” The exclusion of nonambulatory cattle from slaughter for human consumption may strengthen the safety of the food supply and is a prudent measure already in place throughout the European Union.
