Substrate-Dependent Signaling Success In The Wolf Spider, Schizocosa Retrorsa, Eileen Hebets, Damian O. Elias, Andrew C. Mason, Gary L. Miller, Gail E. Stratton

Eileen Hebets Publications

Signals used in communication are often hypothesized to be optimally designed for their signaling environment. Here, we explore the importance of signaling substrate on seismic signal efficacy and reproductive behavior in the wolf spider, Schizocosa retrorsa: a species found on multiple signaling substrates (pine litter and/or red clay or sand). In this multimodal signaling species, simultaneous with conspicuous visual displays, males produce percussive seismic signals via an impulse mechanism which tends to excite a substrate evenly across a wide band of frequencies. We first quantified the transmission characteristics of this broadband percussive signal by playing recorded signals back across three …

Evaluating The Relationship Among Clinical Measures Of Working Memory, Benjamin L. Giesbrecht

Faculty Publications - Doctor of Psychology (PsyD) Program

Working memory is a construct that has received considerable attention and undergone significant theoretical evolution in the past 35 years. Nevertheless, agreement upon a definition of the concept has not occurred. Contributing to this disagreement are the many ways the concept is operationalized, as is evidenced across various standardized tests that purport to measure working memory. The present study examined this relationship among the working memory component of popular cognitive tests, including the Wechsler Adult Intelligence Scale Third Edition, Wechsler Memory Scale -Third Edition, Stanford-Binet Intelligence Scale - Fifth Edition, and the Wide Range Assessment of Memory and Learning - …

Abortion, Persuasion, And Emotion: Implications Of Social Science Research On Emotions For Reading Casey, Jeremy A. Blumenthal

Washington Law Review

Although abortion jurisprudence under Planned Parenthood of Southeastern Pennsylvania v. Casey condones State efforts to persuade a woman to forego an abortion in favor of childbirth, the opinion’s “truthful and not misleading” language can be read more broadly than it traditionally has. Specifically, even a truthful message may mislead when it inappropriately takes advantage of emotional influence to bias an individual’s decision away from the decision that would be made in a non-emotional, fully informed state. Drawing on empirical research in the social sciences, I suggest that the sort of emotional information that many states now provide in their “informed …

Effects Of Neonatal Handling On Play Behavior And Fear Towards A Predator Odor In Juvenile Rats, Stephen M. Siviy

Psychology Faculty Publications

The effects of brief daily separation, also known as "handling," during the first 2 weeks of life on play behavior and fearfulness toward a predatory odor were assessed in juvenile rats. Handled rats were more playful than nonhandled control rats, and while handling had no effect on the direct response of these rats toward a predatory odor, handled rats did not exhibit a conditioned suppression of play when tested later in the same context where they had been exposed to the predatory odor. Handled rats were still wary of the environment in that they continued to show a heightened level …

Historic Genetic Structuring And Paraphyly Within The Great-Tailed Grackle, Jeffrey M. Dacosta, Walter Wehtje, John Klicka

Ornithology Program (HRC)

The Great-tailed Grackle (Quiscalus mexicanus) and Boat-tailed Grackle (Q. major) are sister species that have expanded their ranges during historical times. This expansion has created an area of sympatry between these species in Texas and Louisiana, and between distinctive Great-tailed Grackle subspecies in the southwestern United States and northern Mexico. We investigated the evolutionary histories of both species using mitochondrial DNA sequence data and modern phylogenetic methods. Our results reveal genetic structure within Great-tailed, but not Boat-tailed Grackles. Great-tailed Grackles are separated into two clades, but range expansion in the north has led to secondary contact …

In Vivo Yy1 Knockdown Effects On Genomic Imprinting, Joomyeong Kim, Jeong Do Kim

Faculty Publications

The YY1 transcription factor is predicted to control several imprinted domains, including the Peg3, Gnas and Xist/Tsix regions. To test this possibility, we have used RNA interference strategies to generate transgenic mouse lines that express reduced levels of the cellular YY1 protein. As predicted, lowering YY1 levels resulted in global expression changes in these three imprinted domains. In neonatal brains, most imprinted genes of the Peg3 domain were up-regulated. In the Gnas domain, Nespas was down-regulated, whereas three other imprinted transcripts were up-regulated, including Nesp, Gnasxl and Exon1A. In the Xist/Tsix domain, no obvious change was detected in the expression …

Interactions Between Bacterial Carbon Monoxide And Hydrogen Consumption And Plant Development On Recent Volcanic Deposits, Gary M. King, Carolyn F. Weber

Faculty Publications

Patterns of microbial colonization and interactions between microbial processes and vascular plants on volcanic deposits have received little attention. Previous reports have shown that atmospheric CO and hydrogen contribute significantly to microbial metabolism on Kilauea volcano (Hawaii) deposits with varied ages and successional development. Relationships between CO oxidation and plant communities were not clear, however, since deposit age and vegetation status covaried. To determine plant-microbe interactions in deposits of uniform ages, CO and hydrogen dynamics have been assayed for unvegetated tephra on a 1959 deposit at Puu Puai (PP-bare), at the edge of tree islands within the PP deposit (PP-edge) …

Cellular Uptake And Lysosomal Delivery Of Galactocerebrosidase Tagged With The Hiv Tat Protein Transduction Domain, Xian Yang Zhang, Annie Dinh, James Cronin, Su Chen Li, Jakob Reiser

Faculty Publications

A number of studies have shown that a short peptide, the protein transduction domain (PTD) derived from the HIV-1 Tat protein (Tat-PTD) improved cellular uptake in vitro and distribution in vivo of recombinant proteins bearing such PTDs when administered systemically. To investigate the effects of Tat-PTD addition on the subcellular localization of the lysosomal enzyme galactocerebrosidase (GALC, EC 3.2.2.46) and with a view towards designing improved therapeutic strategies for Krabbe disease (globoid cell leukodystrophy), mouse GALC was tagged C-terminally with the Tat-PTD. Compared with unmodified GALC, GALC bearing a Tat-PTD, a myc epitope and 6 consecutive His residues [GALC-TMH (Tat-PTD, …

"What Are We Missing?" Usability’S Indexical Ground, Alan Zemel, Timothy Koschmann, Curtis Lebaron, Paul Feltovich

Publications

In this paper, we describe how usability provides the indexical ground upon which design work in a surgery is achieved. Indexical and deictic referential practices are used 1) to constitute participation frameworks and work sites in an instructional surgery and 2) to encode and manage participants’ differential access to the relevancies and background knowledge required for the achievement of a successful surgical outcome. As a site for both learning and work, the operating room afforded us the opportunity to examine how usability, which is a critical design consideration, can be used as a resource for learning in interaction. In our …

Nebraska Gap Analysis Project, G. M. Henebry, M. R. Vaitkus, James W. Merchant

United States Geological Survey: Publications

The Nebraska Gap Analysis Project (NE-GAP) began in 1996 to assess the distribution and conservation status of biodiversity in the State under existing land ownership and management regimes. Our objectives were to (1) map land cover linked to dominant vegetation types; (2) map predicted distribution of terrestrial vertebrates; (3) document the representation of natural vegetation communities and animal species in areas managed for the long-term maintenance of biodiversity; and (4) make all information available to resource managers and land stewards in a readily accessible format.

Bifidobacteria In Feces And Environmental Waters, Regina Lamendella, Jorge W. Santo Domingo, Catherine Kelty, Daniel B. Oerther

United States Environmental Protection Agency: Publications

Bifidobacteria have been recommended as potential indicators of human fecal pollution in surface waters even though very little is known about their presence in nonhuman fecal sources. The objective of this research was to shed light on the occurrence and molecular diversity of this fecal indicator group in different animals and environmental waters. Genus- and species-specific 16S rRNA gene PCR assays were used to study the presence of bifidobacteria among 269 fecal DNA extracts from 32 different animals. Twelve samples from three wastewater treatment plants and 34 water samples from two fecally impacted watersheds were also tested. The species-specific assays …

The author speaks to the rising female population numbers, the types of crimes and behaviors that lead to their incarceration, the characteristics of female offenders, the impact their incarceration has on their families and children, and how gender responsive programming is pivotal to their effective and successful reentry into society.

Depression In Parkinson's Disease: Health Risks, Etiology, And Treatment Options, Pasquale G. Frisina, Joan C. Borod, Nancy S. Foldi, Harriet R. Tenenbaum

Publications and Research

Depression is found in about 30%-40% of all patients with Parkinson's disease (PD), but only a small percentage (about 20%) receive treatment. As a consequence, many PD patients suffer with reduced health-related quality of life. To address quality of life in depressed PD patients, we reviewed the literature on the health correlates of depression in PD (eg, cognitive function), etiology of depression in PD, and treatment options (ie, antidepressants, electroconvulsive therapy, and psychotherapy). The current review is unique in its focus on psychosocial aspects, as well as neuropathological factors, of depression in PD. Overall, we conclude that neurochemical (eg, serotonin) …

Hydrodynamics Of Self-Propelled Hard Rods, Aparna Baskaran, M. Cristina Marchetti

Physics - All Scholarship

Motivated by recent simulations and by experiments on aggregation of gliding bacteria, we study a model of the collective dynamics of self-propelled hard rods on a substrate in two dimensions. The rods have finite size, interact via excluded volume and their dynamics is overdamped by the interaction with the substrate. Starting from a microscopic model with non-thermal noise sources, a continuum description of the system is derived. The hydrodynamic equations are then used to characterize the possible steady states of the systems and their stability as a function of the particles packing fraction and the speed of self propulsion.

Leg Sympathetic Response To Noxious Skin Stimuli Is Similar In High And Low Level Human Spinal Cord Injury, M. Kevin Garrison, Alexander V. Ng, Brian D. Schmit

Biomedical Engineering Faculty Research and Publications

Objective

To determine if sympathetically mediated vasoconstriction in the lower extremities is injury level dependent. Although sympathetic responses have been measured in the limbs of people with high and low level SCI using blood flow measurements, including Doppler ultrasound and venous plethysmography, a direct comparison between injury levels has not been made.

Methods

Volunteers with chronic SCI were grouped according to injury level. Above T6: high level (HL, n = 7), and T6 and below: low level (LL, n = 6). All subjects had complete motor and sensory loss. Leg arterial flows were recorded by venous occlusion plethysmography, and continuous …
