Seeing The World Anew: Creative Arts In The Honors Curriculum, Sara Sanders Oct 2001

Seeing The World Anew: Creative Arts In The Honors Curriculum, Sara Sanders

Journal of the National Collegiate Honors Council Online Archive

In the sixteen-year history of the Honors Program at Coastal Carolina University, some three hundred students have completed the program. We have graduated only two fine arts majors, and we currently have a student who is double majoring in art and marine science. Most of our students are science majors. In order to be invited into the honors program, students have to be excellent in verbal and analytical skills, but research on multiple intelligences (Gardner, Multiple) has shown us that those are only two of many ways to make sense of the world. Honors students are usually skilled learners in …


Jesters Freed From Their Jack-In-The-Boxes: Or Springing Creativity Loose From Traditionally Entrenched Honors Students, Leslie Donovan Oct 2001

Jesters Freed From Their Jack-In-The-Boxes: Or Springing Creativity Loose From Traditionally Entrenched Honors Students, Leslie Donovan

Journal of the National Collegiate Honors Council Online Archive

Many people in our society manage adequately all their lives without ever flexing a creative muscle. Yet, most of us involved in Honors education expect and want more for our students. We know that those who resist using creativity in their lives and work will be unlikely to push beyond the traditional boundaries of scholastic analysis. Further, we reason that, by operating beyond such boundaries, our students may someday find a cure for cancer, recognize signs marking sentient life on other planets, or move people to leave hatred of differences behind. We realize that such dreams are possible only if …

Review Of Alien Species In North America And Hawaii: Impacts On Natural Ecosystems By George W. Cox, Roger Sheley Oct 2001

Review Of Alien Species In North America And Hawaii: Impacts On Natural Ecosystems By George W. Cox, Roger Sheley

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This enthusiastic conservationist chronicles the arrival and expansion of many keystone non-indigenous species into North America and Hawaii. A wealth of knowledge is pulled together to provide an overview of the impacts of invasive plants and animals on regional ecosystems. Alien Species should be required reading for natural resource managers.

The author provides regional, biotic, theoretical, and policy perspectives on invasive species and discusses key invasive plants and animals and their known impacts within ten regions. This is the most extensive and documented part of the volume and provides powerful testimony regarding the magnitude of the problem.

Influence Of Habitat On Distribution And Abundance Of The Eastern Woodrat In Kansas, Jon P. Beckmann, Glennis A. Kaufman, Donald W. Kaufman Oct 2001

Influence Of Habitat On Distribution And Abundance Of The Eastern Woodrat In Kansas, Jon P. Beckmann, Glennis A. Kaufman, Donald W. Kaufman

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Anthropogenic modification of native woodlands and grasslands in the Great Plains has altered the abundance and distribution of many species of mammals. To study habitat effects on the eastern woodrat (Neotoma floridana), we surveyed nests of the eastern woodrat in woodlands, grasslands, and croplands along 77 km of secondary roads in three counties in north-central Kansas. All nests were located in woodlands ( < 2 %of habitat), although grasslands and croplands constituted 36% and 62% of habitat surveyed, respectively. In our survey, nests were associated positively with shelterbelts (3.6 nests per 100 m of road edge) but not with shrub patches (1.1 nests per 100 m of road edge) or riparian woodlands (0.3 nests per 100 m of road edge). Consequently, we specifically censused nests in an additional 12 riparian woodlands and 12 shelterbelts. Nests of eastern woodrats were less dense in riparian woodlands (9.4 nests/ha) than in shelterbelts (55.5 nests/ha). Density of woodrat nests decreased as width of a wooded area increased. Further, nests per 100 m of length of woodland did not increase as the width of woodland increased. These patterns suggest that woodland edge, not woodland interior, is the primary factor in abundance of eastern woodrats in this region. Although the eastern woodrat has previously been considered a woodland species, our results suggest that this assessment is incorrect. Our observations demonstrate that anthropogenic modification of the Great Plains, in the form of planted shelterbelts and expanded riparian woodland, likely has increased the distribution and abundance of eastern woodrats, compared to the mid-1800s.


Social Values In The Assessment Of Livestock Grazing In The Great Plains, R. K. Heitschmidt, J. D. Johnson, K. D. Klement Oct 2001

Social Values In The Assessment Of Livestock Grazing In The Great Plains, R. K. Heitschmidt, J. D. Johnson, K. D. Klement

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

We examined the sustainability of the livestock grazing industry in the Great Plains of North America relative to ecological processes, economic viability, and social acceptance. We conclude from the review that livestock grazing is an appropriate use of Great Plains grasslands and, when properly managed, ecologically sustainable. However, we also present evidence that the Great Plains grazing industry is not always economically sustainable or socially acceptable. We attribute this anomaly in large part to the consuming public's general lack of understanding and appreciation for the ecological linkages between current livestock grazing tactics and the evolutionary history of the Great Plains. …


Habitat Fragmentation Effects On Birds In Grasslands And Wetlands: A Critique Of Our Knowledge, Douglas Johnson Oct 2001

Habitat Fragmentation Effects On Birds In Grasslands And Wetlands: A Critique Of Our Knowledge, Douglas Johnson

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Habitat fragmentation exacerbates the problem of habitat loss for grassland and wetland birds. Remaining patches of grasslands and wetlands may be too small, too isolated, and too influenced by edge effects to maintain viable populations of some breeding birds. Knowledge of the effects of fragmentation on bird populations is critically important for decisions about reserve design, grassland and wetland management, and implementation of cropland set-aside programs that benefit wildlife. In my review of research that has been conducted on habitat fragmentation, I found at least five common problems in the methodology used. The results of many studies are compromised by …

Court Review: Volume 38, Issue 3 - Recent Civil Decisions Of The United States Supreme Court: The 2000-2001 Term, Charles H. Whitebread

Court Review: Journal of the American Judges Association

The Supreme Court’s role in the 2000 presidential election sparked intense national debate and will be the sole decision for which this term will be remembered. Although no other decisions rose to same level of political or popular significance, the Court confronted various civil-law topics of particular interest. Among them were issues concerning immigrant rights, interpretation of significant statutes such as the Americans with Disabilities Act, and important matters regarding the First Amendment and federalism.

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The 2000 Missouri River recreational use survey ran 1 April 2000 through 31 December 2000 and covered the Fort Randall Dam to Big Sioux River reach. Recreational user data was collected from postage paid post cards left on vehicles and through personal interviews. Pressure data was collected during a roving survey from ground counts of vehicles, boat trailers, recreational users. Aerial counts were made to compare angling and recreational boating data with ground count data. Recreational users spent an estimated 745,303 hours on the Missouri River survey reach during 2000. Fishing accounted for an estimated 458,749 hours, or 62% of …

Winter Severity And Wolf Predation On A Formerly Wolf-Free Elk Herd, L. David Mech, Douglas W. Smith, Kerry M. Murphy, Daniel R. Macnulty Oct 2001

Winter Severity And Wolf Predation On A Formerly Wolf-Free Elk Herd, L. David Mech, Douglas W. Smith, Kerry M. Murphy, Daniel R. Macnulty

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We studied wolf (Canis lupus) predation on elk (Cervus elaphus) in Yellowstone National Park from 17 March to 15 April 1997 (severe winter conditions) and from 2 to 31 March 1998 (mild winter conditions) 2-3 years after wolves were reintroduced to the park. Elk composed 91% of 117 kills. Data comparisons for 1997 versus 1998 were: hunting success rate, 26% versus 15%; kill rate, 17.1 kg/wolf/day versus 6.1; percent of kill consumed in first day, 7 versus 86; percent femur marrow fat of adult kills, 27 versus 70; calf:adult ratios of kills, 2:33 versus 17:23; sex …

Effects Of Trapping And Subsequent Short-Term Confinement Stress On Plasma Corticosterone In The Brown Treesnake (Boiga Irregularis) On Guam, Tom Mathies, Todd A. Felix, Valentine A. Lance Oct 2001

Effects Of Trapping And Subsequent Short-Term Confinement Stress On Plasma Corticosterone In The Brown Treesnake (Boiga Irregularis) On Guam, Tom Mathies, Todd A. Felix, Valentine A. Lance

United States Department of Agriculture Wildlife Services: Staff Publications

The effects of capture in a live trap and subsequent handling stress on plasma concentrations of corticosterone and other sex steroids were examined in wild male and female brown treesnakes (Boiga irregularis), an introduced species on Guam that has been implicated in the extirpation or decline of many of that island's vertebrate species. Males and females that spent 1 night in a trap had plasma levels of corticosterone about four and two times higher, respectively, than those of the respective free-ranging controls. Mean plasma levels of corticosterone of snakes that had spent 3 nights in a trap were …

Porcine Zona Pellucida Immunocontraception: Long-Term Health Effects On White-Tailed Deer, Lowell A. Miller, Ken Crane, Stan Gaddis, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

As part of a 9-year study on the contraceptive effects of Porcine Zona Pellucida (PZP) on white-tailed deer (Odocoileus virginianus), we analyzed serum chemistry panels during the first 4 years. This included the first 2 years when does were being actively immunized, and 2 years post-immunization. The chemistry panel was designed to detect pathologies that might result from the immunization of the deer. Blood chemistry results did not suggest any pathological changes resulting from the immunization. Seasonal differences in serum cholesterol were similar in both the control and PZP-treated groups. Seasonal changes in the mean body weights of …


Decline Of The Red-Winged Blackbird Population In Ohio Correlated To Changes In Agriculture (1965-1996), Bradley F. Blackwell, Richard A. Dolbeer Oct 2001

Decline Of The Red-Winged Blackbird Population In Ohio Correlated To Changes In Agriculture (1965-1996), Bradley F. Blackwell, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Based on North American Breeding Bird Survey (BBS) data since 1966, Ohio has traditionally hosted 1 of the highest breeding season densities of red-winged blackbirds (Agelaius phoeniceus) of any U.S. state or Canadian province. However, from 1966 through 1996, breeding populations of red-winged blackbirds in Ohio showed a marked decline (x̅ % change/yr in birds per route = -3.9), with breeding population indices decreasing by over 53%. Because the red-winged blackbird successfully adapted to habitats created by agricultural expansion over the last century and became a recognized pest of crops such as corn (Zea mays), …


The Bovine Herpesvirus 1 Immediate-Early Protein (Bicp0) Associates With Histone Deacetylase 1 To Activate Transcription, Yange Zhang, Clinton J. Jones Oct 2001

The Bovine Herpesvirus 1 Immediate-Early Protein (Bicp0) Associates With Histone Deacetylase 1 To Activate Transcription, Yange Zhang, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Infected-cell protein 0 encoded by bovine herpesvirus 1 (BHV-1) (bICP0) is necessary for efficient productive infection, in large part, because it activates all 3 classes of BHV-1 genes (U. V. Wirth, C. Fraefel, B. Vogt, C. Vlcek, V. Paces, and M. Schwyzer, J. Virol. 66:2763–2772, 1992). Although bICP0 is believed to be a functional homologue of herpes simplex virus type 1-encoded ICP0, the only well-conserved domain between the proteins is a zinc ring finger located near the amino terminus of both proteins. Our previous studies demonstrated that bICP0 is toxic to transfected cells but does not appear to directly induce …


Physid Snails As Sentinels Of Freshwater Nematomorphs, Ben Hanelt, L. E. Grother, John J. Janovy Jr. Oct 2001

Physid Snails As Sentinels Of Freshwater Nematomorphs, Ben Hanelt, L. E. Grother, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Freshwater nematomorphs, or gordiids, are parasitic as larvae, but free-living in aquatic environments as adults. Studies based on the collection of adults have reported gordiids to be widespread, but discontinuous in distribution. However, a relatively short adult life span and unknown life history make the detection of adults difficult. An alternative approach to investigate gordiid distribution is to use cysts. Of all paratenic hosts, snails were chosen because they lacked internal defense reactions to the cysts and become easily infected. Here, it is reported that the occurrence of gordiids on the basis of the cyst stage is much more common …

Epimerite-Host Epithelium Relationships Among Eugregarines Parasitizing The Damselflies Enallagma Civile And Ischnura Verticalis, Tamara J. Percival Cook, John J. Janovy Jr., Richard E. Clopton

John J. Janovy, Jr. Publications

The host-parasite interface between two species of damselflies and four species of eugregarines was examined at the ultrastructural level. Nubenocephalus nebraskensis organisms attached to the host midgut epithelium by means of a sucker-like protomerite; the space between the epicytic folds and host epithelium was filled with electron-dense material interpreted to be adhesive in nature. Actinocephalus carrilynnae organisms attached by means of the epimerite, which had no epicytic folds, and by the fluted stalk with characteristic epicytic folds; host cell and parasite membranes appeared fused at some places on the epimerite. Hoplorhynchus acanthatholius organisms attached by means of an ovoid epimerite …


Essays On Ecological Classics: Discovering An Effect Of Insect Floral Herbivory On Plant Population Density And Distribution In A "Green World", Svata M. Louda Oct 2001

Essays On Ecological Classics: Discovering An Effect Of Insect Floral Herbivory On Plant Population Density And Distribution In A "Green World", Svata M. Louda

Svata M. Louda Publications

Could insect herbivory be a significant factor influencing the population density of some native plants? I first asked this question in 1971, and this led me to the research that was acknowledged by the 1982 Mercer Award. The question occurred to me in the context of studying the controversy over trophic structure dynamics (Hairston et al. 1960, Murdoch 1966, Ehrlich and Birch 1967, Slobodkin et al. 1967). At the time, herbivory was not considered an important factor affecting either the abundance or the distribution of plant populations.

In my experiments (1973-1978), I compared seed production and subsequent seedling and juvenile …


Energetics And Cooperativity In Three-Center Hydrogen Bonding Interactions. Ii. Intramolecular Hydrogen Bonding Systems, Ruben D. Parra, Bing Gong, Xiao Cheng Zeng Oct 2001

Energetics And Cooperativity In Three-Center Hydrogen Bonding Interactions. Ii. Intramolecular Hydrogen Bonding Systems, Ruben D. Parra, Bing Gong, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

High level ab initio calculations have been carried out on a number of intramolecular two- and three-center H-bonding structures containing the amide motif, NHC=O. These structures serve as model systems for probing the stability of intramolecular three-center H bonds of the type A1HA2. Particular attention is given to cooperative effects in the three-center H-bonding structures. A systematic assessment of cooperativity for intramolecular H-bonding systems is presented.

Phylogenetic systematic analysis of the genera of the Pronocephalidae including Buckarootrema and Notopronocephalus, …


Diversity And Productivity In A Long-Term Grassland Experiment, David Tilman, Peter B. Reich, Johannes Knops, David A. Wedin, Troy Mielke, Clarence Lehman Oct 2001

Diversity And Productivity In A Long-Term Grassland Experiment, David Tilman, Peter B. Reich, Johannes Knops, David A. Wedin, Troy Mielke, Clarence Lehman

School of Biological Sciences: Faculty Publications

Plant diversity and niche complementarity had progressively stronger effects on ecosystem functioning during a 7-year experiment, with 16-species plots attaining 2.7 times greater biomass than monocultures. Diversity effects were neither transients nor explained solely by a few productive or unviable species. Rather, many higher-diversity plots outperformed the best monoculture. These results help resolve debate over biodiversity and ecosystem functioning, show effects at higher than expected diversity levels, and demonstrate, for these ecosystems, that even the best-chosen monocultures cannot achieve greater productivity or carbon stores than higher-diversity sites.

Beliefs Of Science Teachers Toward The Teaching Of Science/Technological/Social Issues: Are We Addressing National Standards?, Jon E. Pedersen, Samuel Totten Oct 2001

Beliefs Of Science Teachers Toward The Teaching Of Science/Technological/Social Issues: Are We Addressing National Standards?, Jon E. Pedersen, Samuel Totten

Department of Teaching, Learning, and Teacher Education: Faculty Publications

As science educators, we must view the changing nature of society brought on by technology and the global nature of society as an impetus to reexamine the nature of science instruction. We have been bestowed with the responsibility to educate students on a variety of topics that less than two decades ago did not exist. Many of these social issues are controversial in nature and are directly linked to the local, regional, national, and global communities in which we exist. However, including these social issues in the extant curriculum of science has, at best, been limited. This is true even …


Correlation Between Histone Lysine Methylation And Developmental Changes At The Chicken Β-Globin Locus, Michael D. Litt, Melanie A. Simpson, Miklos Gaszner, D. David Allis, Gary Felsenfeld Sep 2001

Correlation Between Histone Lysine Methylation And Developmental Changes At The Chicken Β-Globin Locus, Michael D. Litt, Melanie A. Simpson, Miklos Gaszner, D. David Allis, Gary Felsenfeld

Department of Biochemistry: Faculty Publications

Methylation of histones at specific residues plays an important role in transcriptional regulation. Chromatin immunoprecipitation of dimethylated lysine 9 on histone H3 across 53 kilobases of the chicken β-globin locus during erythropoiesis shows an almost complete anticorrelation between regions of elevated lysine 9 methylation and acetylation. Lysine 9 is methylated most over constitutive condensed chromatin and developmentally inactive globin genes. In contrast, lysine 4 methylation of histone H3 correlates with H3 acetylation. These results lead us to propose a mechanism by which the insulator in the β-globin locus can protect the globin genes from being silenced by adjacent condensed chromatin.


In Vitro Enzymatic Chlorophyll Catabolism In Wheat Elicited By Cereal Aphid Feeding, Xinzhi Ni, Sharron S. Quisenberry, John P. Markwell, Tiffany Heng-Moss, Leon G. Higley, Frederick P. Baxendale, Gautam Sarath, Robert Klucas Sep 2001

In Vitro Enzymatic Chlorophyll Catabolism In Wheat Elicited By Cereal Aphid Feeding, Xinzhi Ni, Sharron S. Quisenberry, John P. Markwell, Tiffany Heng-Moss, Leon G. Higley, Frederick P. Baxendale, Gautam Sarath, Robert Klucas

Department of Entomology: Faculty Publications

Chlorophyll degradation is a complex phenomenon that often accompanies insect feeding damage to plants. Loss of chlorophyll can be initiated by several reactions, including oxidative bleaching, chlorophyllase activity, and Mg-dechelatase activity. Extracts from the Russian wheat aphid [Diuraphis noxia (Mordvilko)], the bird cherry-oat aphid [Rhopalosiphum padi (L.)], and aphid-infested and uninfested wheat plants were assayed in vitro for activities involved in chlorophyll degradation. Although the initial infestation was the same (10 apterous adults) for both aphid species, D. noxia weight was significantly higher than R. padi after feeding for 12 days. Consequently, D. noxia feeding caused greater fresh …

Abstract Chief Academic Officer (CAO) is the most common position title before assuming the presidency of a college or university. Results from a national survey are used to develop a profile of the CAO in each respective Carnegie institutional classification. The typical CAO in four-year institutions is Caucasian, male, 54 years old, and married. He holds a doctoral degree, most likely in humanities or social sciences, and has held the CAO position for 5 or fewer years. Most often, the CAO served as a Dean or Associate Dean in the previous position. All CAOs have classroom experience, but 3% have …
