Preliminary Analysis Of The Geriatric Intelligence Test, Adam W. Fominaya Jan 2012

Preliminary Analysis Of The Geriatric Intelligence Test, Adam W. Fominaya

ETD Archive

The Wechsler Abbreviated Scale of Intelligence was not designed specifically for older adults. Many potential confounding factors occur with greater frequency in the elderly population and these may make the WASI a less appropriate measure of general cognitive functioning. This preliminary study aimed to develop the Geriatric Intelligence Test (GIT). Items were piloted on older adults (>80) who also completed two WASI Subtests. Preliminary results show that multiple GIT subtests are strong predictors of WASI subtest scores and showed good internal consistency. Results will be used to develop a more parsimonious version of the test

Distributed Biogeography Based Optimization For Mobile Robots, Arpit Shah Jan 2012

Distributed Biogeography Based Optimization For Mobile Robots, Arpit Shah

ETD Archive

I present hardware testing of an evolutionary algorithm (EA) known as distributed biogeography based optimization (DBBO). DBBO is an extended version of biogeography based optimization (BBO). Typically, EAs require a central computer to control the evaluation of candidate solutions to some optimization problem, and to control the sharing of information between those candidate solutions. DBBO, however, does not require a centralized unit to control individuals. Individuals independently run the EA and find a solution to a given optimization problem. Both BBO and DBBO are based on the theory of biogeography, which describes how organisms are distributed geographically in nature. I …

Lazy User Theory And Interpersonal Communication Networks, James D. Hayes

ETD Archive

This research examines individual adoption and use of communication technologies through a communication perspective by utilizing concepts from the lazy user theory of solution selection. The user state (individual technology use characteristics) and peer communication are hypothesized to predict switching costs (communication device satisfaction) and laziness. A survey of 687 individuals consisting of college students, Facebook, and Reddit.com users collected data later subjected to exploratory factor analysis and multiple regression. Factor analysis revealed four aspects of user state portable tech-ers, onliners, workers, and relationshipers three types of peer communicators conversationalists, web-referencers, and peer superiors and one type of switching cost, …


Electrocardiogram Signal Quality Comparison Between A Dry Electrode And A Standard Wet Electrode Over A Period Of Extended Wear, Jamie Rae Schofield Jan 2012

Electrocardiogram Signal Quality Comparison Between A Dry Electrode And A Standard Wet Electrode Over A Period Of Extended Wear, Jamie Rae Schofield

ETD Archive

The use of a dry electrode (DE), which does not rely on electrolytic solution, may circumvent potential disadvantages of a wet electrode (WE). The accuracy of the electrocardiogram (ECG) signal, provided by the electrode, is vital. The purpose of the study was to investigate if differences in signal quality, reflected by the signal-to-noise ratio (SNR), existed between the standard gel 3MTM Red DotTM 2560 electrode (WE) and the Orbital Research Incorporated (ORI) dry electrode (DE) over a 96 hour period of continuous wear. Assessments were made within electrode types, comparing potential signal deterioration within the electrode over time, and also …


Boronic Acid Macroligands For Glycomics Applications, Poornima Pinnamaneni Jan 2012

Boronic Acid Macroligands For Glycomics Applications, Poornima Pinnamaneni

ETD Archive

Cell surface carbohydrates existing as glycoproteins and glycolipids represent the first information about the cell with the outside world and are closely involved in various biological processes such as cell communication, and the molecular recognition and cell targeting. However, the mechanisms of most of the processes at the molecular level are still unclear. It is therefore very important to develop specific carbohydrate-binding molecules for a fast, efficient, sensitive and accurate analysis of complex carbohydrates structures and functions, known as glycomics. In addition, certain carbohydrate-binding molecules can be used in medical applications such as biomarkers for diseases diagnosis and targeted drug …

Acoustic And Perceptual Analyses Of The Fundamental Frequencies Of African American And Caucasian Males And Females, Rose A. Vargo

ETD Archive

Normative data compiled by Hixon and Abbs (1980) continue to serve as guidelines for fundamental frequency (F0). These normative data were collected solely from Caucasian participants and may not accurately reflect norms for other ethnicities. According to published literature regarding pitch differences among racial groups, African Americans are believed to have a lower F0 than their Caucasian counterparts.This study investigated differences in F0 between African American and Caucasian young adults. Twenty adults between the ages of 18 and 30 were examined along three vocal parameters: sustained vowel phonation, a speaking task, and a reading task. Three experienced speech-language pathologists and …


Differences In Risk-Taking In A Trauma Exposed Population, Ruth Anna Viehoff Jan 2012

Differences In Risk-Taking In A Trauma Exposed Population, Ruth Anna Viehoff

ETD Archive

Previous studies have shown that depression and posttraumatic stress disorder (PTSD) are associated with a variety of risk-taking behaviors. However fewer studies have examined how comorbidity between the two disorders can differentially affect risk-taking. This study examined the relationship between depression, PTSD, past risk-taking, and perceived benefits of risk to further determine how comorbidity affects risk behaviors. It was expected that individuals who displayed symptoms of depression and PTSD would report more past risk-taking and associate greater benefits with taking risks. Depression symptoms were found to significantly predict past drug use. This suggests that comorbid individuals who report more depressive …


Positive Pollutions And Cultural Toxins, John Blair Gamber Jan 2012

Positive Pollutions And Cultural Toxins, John Blair Gamber

University of Nebraska Press: Sample Books and Chapters

In this innovative study, Positive Pollutions and Cultural Toxins, John Blair Gamber examines urbanity and the results of urban living—traffic, garbage, sewage, waste, and pollution—arguing for a new recognition of all forms of human detritus as part of the natural world and thus for a broadening of our understanding of environmental literature. While much of the discourse surrounding the United States’ idealistic and nostalgic views of itself privileges “clean” living (primarily in rural, small-town, and suburban settings), representations of rurality and urbanity by Chicanas/Chicanos, African Americans, Asian Americans, and Native Americans, on the other hand, complicate such generalization. Gamber …


Almost Somewhere, Suzanne Roberts Jan 2012

Almost Somewhere, Suzanne Roberts

University of Nebraska Press: Sample Books and Chapters

Day One, and already she was lying in her journal. It was 1993, Suzanne Roberts had just finished college, and when her friend suggested they hike California’s John Muir Trail, the adventure sounded like the perfect distraction from a difficult home life and thoughts about the future. But she never imagined that the twenty-eight-day hike would change her life. Part memoir, part nature writing, part travelogue, Almost Somewhere is Roberts’s account of that hike.

John Muir had written of the Sierra Nevada as a “vast range of light,” and this was exactly what Roberts was looking for. But traveling with …

Inheritance Of Humeral Spotting In The Croaking Gourami (Osphronemidae: Trichopsis Vittatus), Jack Frankel, Lisa Alder-Golden, Andre Porter Jan 2012

Inheritance Of Humeral Spotting In The Croaking Gourami (Osphronemidae: Trichopsis Vittatus), Jack Frankel, Lisa Alder-Golden, Andre Porter

Department of Biology Faculty Publications

The croaking gourami (Trichopsis vittatus) exhibits two phenotypes associated with humeral spotting. Fish possess a prominent, dark humeral patch or spot located behind the operculum or lack this spotting pattern. Segregation patterns observed from the progenies of eleven different crosses support the hypothesis that the inheritance of humeral spotting in T. vittatus is controlled by the action of a single autosomal locus, with complete dominance of the allele controlling the spotted phenotype.

Effectiveness Of Three Decontamination Treatments Against Influenza Virus Applied To Filtering Facepiece Respirators, Michael B. Lore, Brian K. Heimbuch, Teanne L. Brown, Joseph D. Wander, Steven H. Hinrichs

United States Air Force: Publications

Filtering facepiece respirators (FFRs) are recommended for use as precautions against airborne pathogenic microorganisms; however, during pandemics demand for FFRs may far exceed availability. Reuse of FFRs following decontamination has been proposed but few reported studies have addressed the feasibility. Concerns regarding biocidal efficacy, respirator performance post decontamination, decontamination cost, and user safety have impeded adoption of reuse measures. This study examined the effectiveness of three energetic decontamination methods [ultraviolet germicidal irradiation (UVGI), microwave-generated steam, and moist heat] on two National Institute for Occupational Safety and Health-certified N95 FFRs (3M models 1860s and 1870) contaminated with H5N1. An aerosol settling …

Culture Ontogeny: Lifespan Development Of Religion And The Ethics Of Spiritual Counselling, Glen Milstein, Amy Manierre Jan 2012

Culture Ontogeny: Lifespan Development Of Religion And The Ethics Of Spiritual Counselling, Glen Milstein, Amy Manierre

Publications and Research

The counsellor has an ethical obligation to treat the whole person. Humans are cultural beings and the foundation of most cultures is religion. Religion and culture are received from our early relation~ ships and modified through later relationships across the lifespan. The paper introduces the term "culture ontogeny" to emphasize that this is a biological process wherein abstract ideas of culture and religion become material in the developing neurophysiology of each brain. A framework and methods are offered to examine the changing roles of religion in clients' emotional self~ structure, inclusive of those who describe themselves as spiritual, not religious. …


Estimating Climate Trends: Application To United States Plant Hardiness Zones, Nir Krakauer Jan 2012

Estimating Climate Trends: Application To United States Plant Hardiness Zones, Nir Krakauer

Publications and Research

The United States Department of Agriculture classifies plant hardiness zones based on mean annual minimum temperatures over some past period (currently 1976–2005). Since temperatures are changing, these values may benefit from updating. I outline a multistep methodology involving imputation of missing station values, geostatistical interpolation, and time series smoothing to update a climate variable’s expected value compared to a climatology period and apply it to estimating annual minimum temperature change over the coterminous United States. I show using hindcast experiments that trend estimation gives more accurate predictions of minimum temperatures 1-2 years in advance compared to the previous 30 years’ …

Weaver, L.D. Mccabe, G.P. Mccabe, R. Novotny, M.D. Van Loan, S. Going, V. Matkovic, C.J. Boushey, D.A. Savaiano

Department of Anthropology: Faculty Publications

Variation in structural geometry is present in adulthood, but when this variation arises and what influences this variation prior to adulthood remains poorly understood. Ethnicity is commonly the focus of research of skeletal integrity and appears to explain some of the variation in quantification of bone tissue. However, why ethnicity explains variation in skeletal integrity is unclear.
Methods
: Here we examine predictors of bone cross sectional area (CSA) and section modulus (Z), measured using dual-energy X-ray absorptiometry (DXA) and the Advanced Hip Analysis (AHA) program at the narrow neck of the femur in adolescent (9–14 years) girls (n …


Defining "Weapons Of Mass Destruction", W. Seth Carus Jan 2012

Defining "Weapons Of Mass Destruction", W. Seth Carus

WMD Occasional Papers

In January 2005, Secretary of Defense Donald Rumsfeld directed that U.S. Strategic Command become “the lead combatant commander for integrating and synchronizing DOD [Department of Defense] in combating WMD [weapons of mass destruction].” This assignment was in response to the White House’s December 2002 National Strategy to Combat Weapons of Mass Destruction.

The Secretary’s memorandum, however, raised a thorny definitional problem with clear bureaucratic implications: what are weapons of mass destruction? Unfortunately, that is not an easily answered question. There are numerous definitions of WMD with some official or semi-official standing (more than 40 are identified in this paper), although …


Out Of Florida: Mtdna Reveals Patterns Of Migration And Pleistocene Range Expansion Of The Green Anole Lizard (Anolis Carolinensis), Shane C. Campbell-Staton, Rachel M. Goodman, Niclas Backström, Scott V. Edwards, Jonathan B. Losos, Jason J. Kolbe Jan 2012

Out Of Florida: Mtdna Reveals Patterns Of Migration And Pleistocene Range Expansion Of The Green Anole Lizard (Anolis Carolinensis), Shane C. Campbell-Staton, Rachel M. Goodman, Niclas Backström, Scott V. Edwards, Jonathan B. Losos, Jason J. Kolbe

Biological Sciences Faculty Publications

Anolis carolinensis is an emerging model species and the sole member of its genus native to the United States. Considerable morphological and physiological variation has been described in the species, and the recent sequencing of its genome makes it an attractive system for studies of genome variation. To inform future studies of molecular and phenotypic variation within A. carolinensis, a rigorous account of intraspecific population structure and relatedness is needed. Here, we present the most extensive phylogeographic study of this species to date. Phylogenetic analyses of mitochondrial DNA sequence data support the previous hypothesis of a western Cuban origin …

Vegetation And Invertebrate Community Response To Eastern Hemlock Decline In Southern New England, Laura L. Ingwell, Mailea Miller-Pierce, R. Talbot Trotter Iii, Evan L. Preisser

Biological Sciences Faculty Publications

The introduction of Adelges tsugae (Hemlock Woolly Adelgid [HWA]) to the eastern United States has had a devastating impact on Tsuga canadensis (Eastern Hemlock). Although much research has been done to assess HWA impacts on ecosystem processes and vegetation structure, few researchers have examined community-level changes in highly infested forest stands. Here we assess the impact of Eastern Hemlock mortality on vegetation and invertebrate diversity and community structure by comparing low-impact (healthy) stands and stands heavily impacted by HWA. We sampled the vegetative and invertebrate diversity of 8 sites (4 low impact and 4 high impact) in the summer and …

Pharmacy Practice and Clinical Research Faculty Publications

Biofilm embedded bacterial pathogens such as Staphylococcus spp., Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii are difficult to eradicate and are major sources of bacterial infections. New drugs are needed to combat these pathogens. Hypericum is a plant genus that contains species known to have antimicrobial properties. However, the specific constituents responsible for the antimicrobial properties are not entirely known, nor have most compounds been tested as inhibitors of biofilm development. The investigation presented here tested seven secondary metabolites isolated from the species Hypericum densiflorum, Hypericum ellipticum, Hypericum prolificum, and Hypericum punctatum as inhibitors of …
