Photo-Induced Charge Movement (Picm) Sensors: Using Bathocuproine To Detect Mgcl2, Fecl2, Cucl2, And Cucl, Svetlana Shkolyar

All Volumes (2001-2008)

PICM research deals with the development of sensor arrays for determining the presence and concentration of specific analytes (chemical to be sensed) in solution. The studies described here are preliminary investigations using one analyte per sensor to develop a database of information (i.e. photo-voltages at specified concentrations, selectivity, and other patters that could follow from the experimental data). The purpose of using one sensor at a time to test one analyte at a time is to develop the database and thus the knowledge to produce successful sensor arrays or even a small, portable sensor in the future. The goal of …

Therapeutic Heat: Effects Of Superficial And Deep Heating Modalities On Hamstring Flexibility, Nicole Lee Lounsberry

All Volumes (2001-2008)

Poor muscle flexibility has often been associated with injury. Therapeutic heating modalities are frequently used to increase the extensibility of the muscle. The purpose of this study was to compare immediate changes in hamstring flexibility following the application of superficial (moist heat pack) and deep (1 MHz ultrasound) heating modalities. Twenty-four college aged subjects met the inclusion criteria and volunteered for this study. Subjects reported to the Athletic Training Lab and received either the ultrasound or moist heat pack treatment. Hamstring flexibility was measured pre and post treatment using an active knee extension test with an inclinometer. An average of …

Adaptive Management: Background For Stakeholders In The Missouri River Recovery Program, Heida Diefenderfer, Craig Fleming

United States Army Corps of Engineers, Omaha District

Since adaptive ecosystem management was described, the need for such a process has been widely recognized by restoration ecologists and managers. In the United States, for example, the National Research Council (NRC) has recommended that ecological restoration projects be designed and executed according to the principles of adaptive planning and management. The NRC report highlights the fact that inflexible restoration goals and plans are unlikely to succeed given that knowledge of natural and social systems is imperfect. As the restoration ecologist John Cairns, Jr., stated: “whatever restoration measures we take, the outcome is highly uncertain.” The reliable existence …

Missouri River Recovery Program: Shallow Water Habitat Program

United States Army Corps of Engineers, Omaha District

Historically, the Missouri River was a shallow, shifting river well known for muddy waters and rapidly changing channel conditions. The dynamic river provided a wide range of depth, velocity and sediment conditions. Within this environment, the amount of shallow water habitat was quite prevalent, with estimated amounts of more than 100 acres per mile. Shallow water habitat is an aquatic area less than five feet deep where the river flows slowly – less than two feet per second.

Over the years, the U.S. Army Corps of Engineers has been charged by Congress to remove snags, protect banks, construct navigation channels …

A Survey Of Registered Dietitians' Perceptions Of Constructivist And Behaviorist Instructional Approaches And Delivery Methods In Accredited Dietetics Programs, Martha A. Smith

Master's Theses and Doctoral Dissertations

This purpose of this research study was to test learning theories and models of teaching (constructivist vs. behaviorist) used in dietetic education programs. Additionally, the focus of accreditation for dietetics education is the quality and integrity of a program regardless of its instructional delivery method. Therefore, this study examined the variations between on-line and on-campus delivery methods.

Research questions that guided this study included:

1) To what extent do educators use constructivist or behaviorist theoretical approaches during instructional delivery?

2) What are the differences in learning between on-line education and oncampus delivery methods?

3) As far as constructivist and behaviorist …

Food For Thought: An Examination Of The Relationship Between Binge Eating And Psychological Variables In A Diverse College-Student Population, Valentina Ivezaj

Master's Theses and Doctoral Dissertations

Binge eating is associated with a host of adverse outcomes, but little is known about sex and racial differences among those who binge eat. The present study examined sex and racial group differences in binge eating within a college-student population. It was hypothesized that White women would endorse higher rates of binge eating than the other groups, and that predictors of binge eating would differ across groups. Participants completed a web-based survey assessing depression, anxiety, body image, weight history, physical activity, smoking, and body mass index. Findings highlight sex and racial differences in the predictors of binge eating, with depression …

Self-Care And Burnout Among Professional Clinical Therapists, Laurie Diane Roach

The purpose of this study was to determine the extent to which self-care helps to prevent and/or to protect against burnout among professional clinical therapists. The research for this study was conducted to look at the importance of incorporating self-care into social workers' daily routines and the effects that doing so could have on the prevention of or protection against burnout.

The Public Domain: Enclosing The Commons Of The Mind, James Boyle

A repository of copyright educational resources for higher education

Used in many intro to copyright law classes, this enlightening book describes what author James Boyle “calls the range wars of the information age today’s heated battles over intellectual property. Boyle argues that just as every informed citizen needs to know at least something about the environment or civil rights, every citizen should also understand intellectual property law. Why? Because intellectual property rights mark out the ground rules of the information society, and today’s policies are unbalanced, unsupported by evidence, and often detrimental to cultural access, free speech, digital creativity, and scientific innovation.”

Metapopulation Dynamics Override Local Limits On Long‐Term Parasite Persistence, Karthik Ram, Evan L. Preisser, Daniel S. Gruner, Donald R. Strong

Biological Sciences Faculty Publications

A simple null model, particularly germane to small and vulnerable organisms such as parasites, is that local conditions set a stage upon which larger‐scale dynamics play out. Soil moisture strongly influences survival of entomopathogenic nematodes (EPN), which in turn drive trophic cascades by protecting vegetation from root‐feeding herbivores. In this study, we examine the mechanisms responsible for patchy occurrence of an entomopathogenic nematode, Heterorhabditis marelatus, in a California coastal prairie. One hypothesis proposes that biotic factors such as competition and natural enemies could regulate occurrence of EPN populations. We found that fungi and other enemies of EPN, although locally potent, …

From Individuals To Ecosystem Function: Toward An Integration Of Evolutionary And Ecosystem Ecology, Oswald J. Schmitz, Jonathan H. Garbowski, Barbara L. Peckarsky, Evan L. Preisser, Geoffrey C. Trussell, James R. Vonesh

Biological Sciences Faculty Publications

An important goal in ecology is developing general theory on how the species composition of ecosystems is related to ecosystem properties and functions. Progress on this front is limited partly because of the need to identify mechanisms controlling functions that are common to a wide range of ecosystem types. We propose that one general mechanism, rooted in the evolutionary ecology of all species, is adaptive foraging behavior in response to predation risk. To support our claim, we present two kinds of empirical evidence from plant‐based and detritus‐based food chains of terrestrial and aquatic ecosystems. The first kind comes from experiments …

A Bac-Based Integrated Linkage Map Of The Silkworm Bombyx Mori, Kimiko Yamamoto, Junko Nohata, Keiko Kadono-Okuda, Junko Narukawa, Motoe Sasanuma, Shun-Ichi Sasanuma, Hiroshi Minami, Michihiko Shimomura, Yoshitaka Suetsugu, Yutaka Banno, Kazutoyo Osoegawa, Pieter J. De Jong, Marian R. Goldsmith, Kazuei Mita

Biological Sciences Faculty Publications

Background: In 2004, draft sequences of the model lepidopteran Bombyx mori were reported using whole-genome shotgun sequencing. Because of relatively shallow genome coverage, the silkworm genome remains fragmented, hampering annotation and comparative genome studies. For a more complete genome analysis, we developed extended scaffolds combining physical maps with improved genetic maps.

Results: We mapped 1,755 single nucleotide polymorphism (SNP) markers from bacterial artificial chromosome (BAC) end sequences onto 28 linkage groups using a recombining male backcross population, yielding an average inter-SNP distance of 0.81 cM (about 270 kilobases). We constructed 6,221 contigs by fingerprinting clones from three BAC libraries digested …

Different Requirements Of The Swi/Snf Complex For Robust Nucleosome Displacement At Promoters Of Heat Shock Factor And Msn2- And Msn4-Regulated Heat Shock Genes, Tamara Y. Erkina, P. A. Tschetter, Alexander M. Erkine

Scholarship and Professional Work – COPHS

The stress response in yeast cells is regulated by at least two classes of transcription activators—HSF and Msn2/4, which differentially affect promoter chromatin remodeling. We demonstrate that the deletion of SNF2, an ATPase activity-containing subunit of the chromatin remodeling SWI/SNF complex, eliminates histone displacement, RNA polymerase II recruitment, and heat shock factor (HSF) binding at the HSP12 promoter while delaying these processes at the HSP82 and SSA4 promoters. Out of the three promoters, the double deletion of MSN2 and MSN4 eliminates both chromatin remodeling and HSF binding only at the HSP12 promoter, suggesting that Msn2/4 activators are primary determinants of …

Guilmette, Raymond Niaura, Richard Bryant, Steven Bruce, Leanne M. Williams, Clark C. Richard, Ronald A. Cohen, Evian Gordon

Psychology Faculty Works

Background: Previous studies have examined the impact of early life stress (ELS) on the gross morphometry of brain regions, including the corpus callosum. However, studies have not examined the relationship between ELS and the microstructural integrity of the brain. Methods: In the present study we evaluated this relationship in healthy non-clinical participants using diffusion tensor imaging (DTI) and self-reported history of ELS. Results: Regression analyses revealed significant reductions in fractional anisotropy (FA) within the genu of the corpus callosum among those exposed to the greatest number of early life stressors, suggesting reduced microstructural integrity associated with increased ELS. These effects …

Thermal Roots Of Correlation-Based Complexity, Philip Fraundorf

Physics Faculty Works

Bayesian maxent lets one integrate thermal physics and information theory points of view in the quantitative study of complex systems. Since net surprisal (a free energy analog for measuring “departures from expected”) allows one to place second law constraints on mutual information (a multimoment measure of correlations), it makes a quantitative case for the role of reversible thermalization in the natural history of invention, and suggests multiscale strategies to monitor standing crop as well. It prompts one to track evolved complexity starting from live astrophysically observed processes, rather than only from evidence of past events. Various gradients and boundaries that …

Morphology Of The Inner And Peripheral Ear Of The Loricariid Catfish Pterygoplichthys Gibbiceps K., Brian David Rogers

Mahurin Honors College Capstone Experience/Thesis Projects

The morphology of the peripheral and inner ear structures was studied in the loricariid catfish Pterygoplichthys gibbiceps. Specimens (n=6) were preserved in fixative (4% paraformaldehyde, 2% glutaraldehyde in 0.1M phosphate buffer) and dissected for examination of the gross morphology (using light microscopy) and ultrastructure of the auditory sensory epithelia (using scanning electron microscopy). One additional specimen was cleaned in a dermestid beetle colony in order to examine the osteology of the skull. The swim bladder of P. gibbiceps is divided along the midline of the fish into two reduced but equal lobes residing in two laterally oriented bony encapsulations. Immediately …

Synthesis Of Phenoxides With Pendant Amines And Catalytic Intramolecular Hydroaminations, Kenneth Awasung

Undergraduate Review

One core focus of my research project, (my 2007 summer research) is to make structural analogs of substituted phenols to support the titanium catalysis of organic compounds. The synthesis and study of these and related ligands, (pyrrolyls, aldimines, salens, and other nitrogen/oxygen heterocycles) is a major field of organometallic chemistry. Bulky phenols and their analogs serve as highly effective ligands to support catalysis due to their sterics and electronics. I have been designing and have begun synthesizing phenol analogs using a series of aldol condensations and michael additions and other organic chemistry methodology to generate new substituted phenols. Our method …

Cross-Disciplinary Collaboration And Learning, Deana D. Pennington

All UNF Research

Complex environmental problem solving depends on cross-disciplinary collaboration among scientists. Collaborative research must be preceded by an exploratory phase of collective thinking that creates shared conceptual frameworks. Collective thinking, in a cross-disciplinary setting, depends on the facility with which collaborators are able to learn and understand each others’ perspectives. This paper applies three perspectives on learning to the problem of enabling cross-disciplinary collaboration: Maslow’s hierarchy of needs, constructivism, and organizational learning. Application of learning frameworks to collaboration provides insights regarding receptive environments for collaboration, and processes that facilitate cross-disciplinary interactions. These environments and interactions need time to develop and require …

Scrabble: An Autoethnography About Adoption, Karen V. Lee

Iowa Journal of Communication

The following autoethnography reflects the author's emotional turmoil when her daughter asks about her birthmother. The moment causes her to reflect on the adoption process and how she lives simultaneously in a culture of love and culture of loss. She copes with the reality that her daughter might want to meet her birthmother one day. As an adoptive mother, she uses the language of adoption, feminism, and postmodernism to share her story. At a deeper level, she realizes that adoption will remain an unresolved issue. In the end, writing the autoethnography becomes transformative as the author gains a heightened awareness …

Plant Phenology And Distribution In Relation To Recent Climate Change, Robert I. Bertin

Biology Department Faculty Scholarship

This paper summarizes a broad range of studies that have examined influences of recent climate change on plant phenology or distribution. Spring events such as leafing and flowering have typically advanced, some by several weeks, with median advances of 4-5 d per degree Celsius. Autumn events, such as leaf coloring or leaf fall, have usually become delayed, though with more variability than spring events. Changes in summer events have been mixed. Phenological changes have varied geographically, as have recent temperature changes. Most studies of at least several decades duration show the initiation of rapid changes in the 1970s or 1980s, …
