Stand Conditions Immediately Following A Restoration Harvest In An Old-Growth Pine-Hardwood Remnant, Don C. Bragg

Journal of the Arkansas Academy of Science

Portions of the Levi Wilcoxon Demonstration Forest (LWDF), a privately owned parcel of old growth pine and hardwoods in Ashley County, Arkansas, were recently treated to restore conditions similar to some historic accounts of the virgin forest. Following a hardwood-only cut, a post-harvest inventory showed that the number of tree species in the sample area declined from 24 in 2006 (the most recent pre-harvest inventory) to 12 in 2009. Loblolly (Pinus taeda L.) and shortleaf (Pinus echinata Mill.) pine now comprise 59.2% of the remaining live trees, up from 16.2% in 2006. Between 2006 and 2009, basal area dropped from …

Effectiveness Of Weight Control Through Weight Watch Programs, V. A. Black, P. Boumtje

Journal of the Arkansas Academy of Science

Linear probability estimation and survey data are employed to quantify the influence of the lifestyles of individuals on the change in their body mass index (BMI). The analysis also explores the effects of demographic characteristics (age, gender, and ethnicity) in weight management. Results suggest evidence of association between changes in lifestyle and changes in the BMI of individuals.

Distribution Of The Southeastern Shrew (Sorex Longirostris Longirostris) In Arkansas, G. A. Mikel, Gary A. Heidt, David W. Clark

Journal of the Arkansas Academy of Science

The southeastern shrew (Sorex longirostris longirostris) is considered uncommon and, due to a lack of knowledge, a Species of Greatest Conservation Need in Arkansas. Also, eastern Arkansas may represent a gap in the species’ distribution. Therefore, we evaluated persistence at previous capture sites, surveyed additional counties, quantified microhabitat at our capture locations, and compiled occurrences. Since Sealander and Heidt’s (1990) Arkansas Mammals detailed its occurrence, additional captures by Huston and Nelson (1994), Showen (2006), and this study document new counties (Pope and Searcy) and a new ecoregion (Arkansas Valley). Number of specimens in Arkansas has increased to 17 in 11 …

Detection Of Inositol Polyphosphates By Polyacrylamide Gel Electrophoresis (Page) Under Apoptotic Conditions In Cultured Sw480 Cells, M. K. Zafar, R. Mohsin, S. Hassen, R. Agarwal, H. Mumtaz, N. Ali

Journal of the Arkansas Academy of Science

Inositol phosphates are naturally occurring compounds that regulate diverse cellular processes including apoptosis. Apoptosis is a mechanism by which cells undergo natural death to maintain cellular homeostasis. It causes cell death in areas during a state that is harmful to the body. It also regulates cellular development. Previous work has shown that exogenously administered, as well as endogenously manipulated inositol phosphates bring about apoptotic changes. It has been demonstrated that cellular levels of inositol phosphates, particularly higher inositol phosphates such as inositol hexakis-phosphate (IP6) and diphosphoinositol pentakis-phosphate (IP7) levels increase during apoptotic conditions. In this study, we have attempted to …

Seasonal Activity Of The Ozark Highlands Leech, Macrobdella Diplotertia, (Annelida: Hirudinea) In North-Central Arkansas, M. Connior, Stanley E. Trauth

Journal of the Arkansas Academy of Science

The Ozark Highlands Leech, Macrobdella diplotertia, occurs intermittently throughout Arkansas, Kansas, and Missouri. Limited natural history of this species is known. Herein, we report a new county occurrence for this leech from a cattle pond in southern Marion County, Arkansas. We also report on the seasonal activity and novel hosts of this species. We surveyed the inhabited pond monthly to determine activity and collected natural history data on this species. This study indicated that this species appears to be most active in spring, summer, and early fall, but inactive during the winter. We also documented five new anuran hosts for …

Cohabiting, Family And Community Stressors, Selection, And Juvenile Delinquency, Christopher A. Kierkus, Brian R. Johnson, John D. Hewitt

Peer Reviewed Publications

Prior research has established that children from traditional, two-parent nuclear families experience a lower risk of delinquency than children raised in alternative family structures. However, many studies have ignored the effect of parental cohabiting on delinquent development. A growing body of research suggests that cohabiting (even among biological parents) may be harmful to children. This study tests the hypothesis that cohabiting is associated with four different types of delinquent behavior. It examines two theoretical models, a family stress model and a community stress/selection model, as possible explanations of ‘‘the cohabiting effect.’’ The analysis reveals that cohabiting is generally associated with …

Aldo Leopold’S Land Ethic And The Great Lakes: A Paradigm For Understanding The Morality Of Aquatic Invasive Species Management, M. Andrew Sanford, John Uglietta, Phd

Student Summer Scholars Manuscripts

Abstract: This essay explores what obligations we have to protect the Great lakes ecosystem from the threat of aquatic invasive species within the context of Aldo Leopold‟s seminal essay in environmental philosophy The Land Ethic. In this essay I argue that Leopold‟s land ethic provides a consistent and dynamic paradigm for how we perceive and protect the natural environment. The land ethic is summarized in what I call Leopold’s Edict which directs us to preserve the health and beauty of the natural environment. The land ethic implies that people interested in conservation must develop a firm understanding of what …

A Chemical Genetics Approach To Elucidate Mechanisms Of The Fission Yeast Polo Kinase In Cell Division, Jennifer Phelan, Dawn Clifford Hart

Student Summer Scholars Manuscripts

Cell division is a fundamental biological event that underlies the growth and development of all organisms. Because human and fission yeast (Schizosaccharomyces pombe) cells divide symmetrically through constriction of the actomyosin ring, fission yeast provides an ideal model system to reveal conserved cell cycle properties. In fission yeast, an evolutionarily conserved protein, Mid1, plays a critical role in organizing the early steps of contractile ring formation. Mid1 functions as a scaffold to bridge the cell cortex with the contractile ring. Cells lacking mid1 form off-centered, highly disorganized ring structures and exhibit severe cell division defects. Our previous research …

The Impact Of Web-Scale Discovery On The Use Of A Library Collection, Doug Way

Scholarly Papers and Articles

Grand Valley State University Libraries implemented Serials Solutions' web-scale discovery tool, Summon, during the fall of 2009. This case study explores whether Summon had an impact on the use of the library's resources during its first semester of implementation. An examination of usage statistics showed a dramatic decrease in the use of traditional abstracting and indexing databases and an equally dramatic increase in the use of full-text resources from full-text database and online journal collections. The author concludes that the increase in full-text use is linked to the implementation of a web-scale discovery tool.

Association Of Workplace Chronic And Acute Stressors With Employee Weight Status: Data From Worksites In Turmoil, Isabel Diana Fernandez, Haiyan Su, Paul C. Winters, Hua Liang

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

Objectives: To examine the independent and joint effects of psychosocial chronic and acute stressors with weight status and to report the intraclass correlation coefficient for body mass index (BMI). Methods: Baseline data on 2782 employees from a group-randomized weight gain prevention intervention were examined to investigate the effect of high job strain and job insecurity on BMI and on the odds of overweight/obesity including potential confounders and mediating variables. Data were analyzed using mixed models. Results: The mediating variables removed the effect of high job strain on weight (β = 0.68, P = 0.07; odds ratios = 1.34, confidence interval …

Don't Judge A Book By Its Cover: The Curious Case Of Wild Ginger Pollination, W. John Hayden

Biology Faculty Publications

What pollinates wild ginger? This seems like an easy question. The inconspicuous little flowers are held close to the forest floor, often completely hidden by a dense canopy of ginger leaves above. Flower color is rather drab, dominated by brown and maroon hues. Wind pollination seems completely unlikely and flowers pollinated by bees, butterflies, moths, or hummingbirds are always much more showy and accessible to these flying creatures. Flies, however, given their natural inclination to seek carrion as a food source for their babies (i.e. maggots), are often attracted to brown and maroon flowers. And because their actual quarry, animal …

Amino Acid Transport In Thermophiles: Characterization Of An Arginine-Binding Protein In Thermotoga Maritima, Matthew S. Luchansky, Bryan S. Der, Sabato D'Auria, Gabriella Pocsfalvi, Luisa Iozzion, Daniela Marasco, Jonathan D. Dattelbaum

Chemistry Faculty Publications

Members of the periplasmic binding protein superfamily are involved in the selective passage of ligands through bacterial cell membranes. The hyperthermophilic eubacterium Thermotoga maritima was found to encode a highly stable and specific periplasmic arginine-binding protein (TM0593). Following signal sequence removal and overexpression in Escherichia coli, TM0593 was purified by thermoprecipitation and affinity chromatography. The ultra-stable protein with a monomeric molecular weight of 27.7 kDa was found to exist as both a homodimer and homotrimer at appreciable concentrations even under strongly denaturing conditions, with an estimated transition temperature of 116 °C. Its multimeric structure may provide further evidence of …

Amino Acid Transport In Thermophiles: Characterization Of An Arginine-Binding Protein In Thermotoga Maritima. 2. Molecular Organization And Structural Stability, Andrea Scirè, Anna Marabotti, Maria Staiano, Luisa Iozzion, Matthew S. Luchansky, Bryan S. Der, Jonathan D. Dattelbaum, Fabio Tanfani, Sabato D'Auria

Chemistry Faculty Publications

ABC transport systems provide selective passage of metabolites across cell membranes and typically require the presence of a soluble binding protein with high specificity to a specific ligand. In addition to their primary role in nutrient gathering, the binding proteins associated with bacterial transport systems have been studied for their potential to serve as design scaffolds for the development of fluorescent protein biosensors. In this work, we used Fourier transform infrared spectroscopy and molecular dynamics simulations to investigate the physicochemical properties of a hyperthermophilic binding protein from Thermotoga maritima. We demonstrated preferential binding for the polar amino acid arginine …

Tuning Σ-Holes: Charge Redistribution In The Heavy (Group 14) Analogues Of Simple And Mixed Halomethanes Can Impose Strong Propensities For Halogen Bonding, Kelling J. Donald, Bernard K. Wittmaack, Chad Crigger

Chemistry Faculty Publications

Halogen bonding between halide sites (in substituted organic molecules or inorganic halides) and Lewis bases is a rapidly progressing area of exploration. Investigations of this phenomenon have improved our understanding of weak intermolecular interactions and suggested new possibilities in supramolecular chemistry and crystal engineering. The capacity for halogen bonding is investigated at the MP2(full) level of theory for 100 compounds, including all 80 MH₄-_nX_n systems (M = C, Si, Ge, Sn, and Pb; X = F, Cl, Br, and I). The charge redistribution in these molecules and the (in)stability of the σ-hole at X as …

Spheroid Detection In 2d Images Using Circular Hough Transform, Priyanka Chaudhary

University of Kentucky Master's Theses

Three-dimensional endothelial cell sprouting assay (3D-ECSA) exhibits differentiation of endothelial cells into sprouting structures inside a 3D matrix of collagen I. It is a screening tool to study endothelial cell behavior and identification of angiogenesis inhibitors. The shape and size of an EC spheroid (aggregation of ~ 750 cells) is important with respect to its growth performance in presence of angiogenic stimulators. Apparently, tubules formed on malformed spheroids lack homogeneity in terms of density and length. This requires segregation of well formed spheroids from malformed ones to obtain better performance metrics. We aim to develop and validate an automated imaging …

Genetic Diversity, Structure, And Recolonization Patterns Of Kentucky Black Bears, John Tyler Hast

University of Kentucky Master's Theses

After nearly a century of absence, the black bear (Ursus americanus) reappeared in Kentucky during the late 20th century and has since increased in number. Recolonization of bears in the southeastern portion of the state was thought to have been caused by emigration of bears from adjacent states into the Commonwealth, while in the south-central area, bears originated, or natural recolonization may have been supplemented by the translocation of 14 individuals into the Big South Fork National River Recreation Area. To investigate the recolonization patterns of bears in Kentucky, I used 20 microsatellite loci to determine the genetic …

Upper Triassic Corals And Carbonate Reef Facies From The Martin Bridge And Hurwal Formations, Wallowa Terrane (Oregon), Megan Ruth Rosenblatt

Graduate Student Theses, Dissertations, & Professional Papers

The diversity and abundance of Late Triassic scleractinian corals and carbonate microfacies were analyzed from the Wallowa terrane (southern Wallowa Mountains, Oregon) in order to determine regional and distant paleogeographic relationships during the Late Triassic time. Systematic identification of coral species and depositional environments between two formations in the Wallowa terrane (Summit Point Member of the Martin Bridge Formation and Excelsior Gulch of the Hurwal Formation) and one locality in the adjacent Olds Ferry terrane (Willow Spring of the “Upper” Huntington Formation) were used to analyze similarities between the Tethys realm (Northern Calcareous Alps) and the terranes of the North …

Mr. Monk And The Emotion-Reason Dilemma, E. Deidre Pribram Ph.D.

Communications: Faculty Publications

Adrian Monk (Tony Shalhoub) belongs to a tradition of brilliant but personally flawed detectives. Like others in this tradition, including his television colleague, Dr. Gregory House (Hugh Laurie), Monk’s genius resides in his exceptional, even excessive, rationality. Both Monk and House embody near-perfect detection or diagnostic skills. And, in both cases, the cause of their damaged personalities is excessive emotionality, represented by their respective emotional disorders. In their internal dynamics, emotion is almost always the ‘problem,’ and both shows suggest that troubled emotionality is the price Monk and House must pay for their intense brilliance.
