Rabies In Virginia, 1989-2003: With Particular Attention To Animals, Geographic Distribution, And Virus Variant, William Andrew Holzgrefe Jan 2004

Rabies In Virginia, 1989-2003: With Particular Attention To Animals, Geographic Distribution, And Virus Variant, William Andrew Holzgrefe

Theses and Dissertations

Objectives: The description of the raccoon rabies epizootic in Virginia over fifteen years (1989-2003). Methods: Using simple statistical methods and a geographic information system (GIS)-based approach, and fifteen years worth of animal surveillance data, the progress of this epizootic has been charted in terms of the geographic spread of the disease, the major animal species affected by the disease and its spread, and the exposure and risk to humans and livestock animals presented by the expansion of the geographic range. Results: The resulting descriptive study illustrates the eastward expansion of the epizootic, the mushrooming of the disease in the northern …

Dis-Patch: Practice As. . . Practice And Research, Jonathan Mustard, Chrissie Parrott Jan 2004

Dis-Patch: Practice As. . . Practice And Research, Jonathan Mustard, Chrissie Parrott

Creative Connections Symposium @ BEAP2004 September 4, 2004

Dis-Patch is the title of a dance work that was partly the outcome of research into ways in which movement in space might successfully correlate to the parameters of sound. The process of making the work in workshops, rehearsals and performance both altered our view of, and added to the background research. It became evident in this process that certain outcomes, whilst alien to musically conventional ears, were nevertheless valid and interesting sonic translations of the choreography. The performance demonstrated how issues within and between disciplines can be re-problematised through the creative and innovative use of technology. It is our …

Phillip Adams, Nanette Hassall

Creative Connections Symposium @ BEAP2004 September 4, 2004

This paper explores the importance of narrative in Phillip Adams’ work. Despite the fact that he is seen by the critics as a member of the ‘post moderns’ in dance in Australia there are significant ways in which we see him depart from the traditional understandings of those terms in order to develop a more idiosyncratic and personal style.

Special Forum On The Philosophy Of Teaching Education As Communication: The Pragmatist Tradition, Chad Edwards, Gregory J. Shepherd Jan 2004

Special Forum On The Philosophy Of Teaching Education As Communication: The Pragmatist Tradition, Chad Edwards, Gregory J. Shepherd

Basic Communication Course Annual

We take the basic course in communication to be a site where associated living is experienced, and where individuals practice the democratic art of referencing and articulating their own behaviors and beliefs to those of others. This democratic practice is associated living is, as American pragmatist and educational philosopher John Dewey insisted, communication itself -- "conjoint communicated experience." In this essay, we provide an overview of this pragmatist educational metaphysic and discuss a few consequences of metaphysical beliefs about education.

Distribution Of Legumes Along Gradients Of Slope And Soil Electrical Conductivity In Pastures, John A. Guretzky, Kenneth J. Moore, C. Lee Burras, E. Charles Brummer Jan 2004

Distribution Of Legumes Along Gradients Of Slope And Soil Electrical Conductivity In Pastures, John A. Guretzky, Kenneth J. Moore, C. Lee Burras, E. Charles Brummer

Department of Agronomy and Horticulture: Faculty Publications

Legumes establish and persist on backslope landscape positions but fail on summits and toeslopes in southeastern Iowa pastures, suggesting that these pastures be managed site specifically. Visual delineation of landscape positions, however, can be difficult, and char- acterization of spatial variability through soil sampling is expensive. Creation of digital elevation models (DEM) and apparent soil electrical conductivity (ECa) mapping are inexpensive alternatives to de- scribing field conditions. Our objective was to examine the relationships of DEM-derived slope, soil ECa, and legume distribution in pastures.We examined these relationships across four 1.4-ha pastures. Each pasture was divided into …

Mobility, Sedentism, And Intensification: Organizational Responses To Environmental And Social Change Among The San Of Southern Africa, Robert K. Hitchcock Jan 2004

Mobility, Sedentism, And Intensification: Organizational Responses To Environmental And Social Change Among The San Of Southern Africa, Robert K. Hitchcock

Department of Anthropology: Faculty Publications

HUNTER-GATHERER ADAPTATIONS included mobility strategies that were geared toward mapping people on to both resources and other people. There are factors that condition the ways in which people position themselves on the landscape and move over it. Mobility strategies are organizational responses to the structural properties of the natural and social environments (Binford 1980, 2001). The logistical component of a settlement system, in which task-specific groups range out from residential locations for purposes of obtaining food, raw materials, or information, is related to the organization of production of a society as well as to the distribution of critical resources in …

An Evaluation Of Economic Efficiencies Of Two Beef Systems From Calving To Harvest, Rosemary V. Anderson, Richard J. Rasby, Dick Clark, Terry J. Klopfenstein, Casey Macken Jan 2004

An Evaluation Of Economic Efficiencies Of Two Beef Systems From Calving To Harvest, Rosemary V. Anderson, Richard J. Rasby, Dick Clark, Terry J. Klopfenstein, Casey Macken

Nebraska Beef Cattle Reports

Spring-calving, crossbred cows were used in a three-year experiment to determine the economic efficiencies of two different beef systems. Cows were either wintered on pasture (Control System) or on cornstalks (Treatment System). Control System steers were transported to a feedlot, fed a finishing diet and slaughtered. Treatment System steers were wintered on cornstalks, grazed pasture, fed a finishing diet and slaughtered. The Treatment System had lower weaning and slaughter breakeven, lower cost per weaned calf and greater profit potential when finished steers were sold on a live basis. Profitability was similar when finished steers were sold on a grid basis.

Carcass Traits And Palatability Attributes Of Herdmates Finished As Calves Or Yearling Steers, Perry S. Brewer, Chris R. Calkins, Richard J. Rasby, Terry J. Klopfenstein, Rosemary V. Anderson Jan 2004

Carcass Traits And Palatability Attributes Of Herdmates Finished As Calves Or Yearling Steers, Perry S. Brewer, Chris R. Calkins, Richard J. Rasby, Terry J. Klopfenstein, Rosemary V. Anderson

Nebraska Beef Cattle Reports

A two-year study compared steers from the same herd finished as calves or yearlings at a fat thickness endpoint of 0.5 in. Yearlings yielded heavier carcasses with larger ribeye areas, lower marbling scores and lower quality grades. Calves produced more tender steaks measured by shear force and a consumer taste panel. The probability of a tough steak (based on shear force) from calf-fed steers was 1.9 and 0.02% for 7 and 21 days of aging, respectively, while the risk for yearlings was 29.2 and 4.0%, respectively. Calf-fed steers produced more tender steaks and, after 21 days of aging, steaks from …

Basis Variability On The Feeder Cattle Contract Versus The Failed Stocker Contract, Dillon Feuz, Sebastian Perversi, Wendy Umberger Jan 2004

Basis Variability On The Feeder Cattle Contract Versus The Failed Stocker Contract, Dillon Feuz, Sebastian Perversi, Wendy Umberger

Nebraska Beef Cattle Reports

Basis variability was compared in 10 markets for 550 and 750 pound steers using the Chicago Mercantile Exchange (CME) stocker and feeder indexes as a proxy for futures prices. Basis variability for 550 pound steers was significantly greater than basis variability for 750 pound steers. As market volume decreased and as volume variability increased, basis variability also increased. The failed CME stocker contract never attracted enough volume to remain a viable contract. One possible explanation for this contract failure is the basis risk associated with it was large enough to discourage producers from using the contract to hedge calves.

Effect Of Conjugated Linoleic Acid On Cell Death In Adipose Tissue, Kim M. Hargrave, Brett J. Meyer, Jess L. Miner Jan 2004

Effect Of Conjugated Linoleic Acid On Cell Death In Adipose Tissue, Kim M. Hargrave, Brett J. Meyer, Jess L. Miner

Nebraska Beef Cattle Reports

Mice fed conjugated linoleic acid (CLA) lose body fat. This loss of body fat is accompanied by an increases in DNA fragmentation, indicative of apoptosis or programmed cell death. Adipose apoptosis was observed in mice fed the trans-10, cis-12 isomer or a mixture of isomers but not the cis-9,trans-11 isomer. The trans-10,cis-12 isomer also induced DNA fragmentation in preadipocytes in vitro, but not mature adipocytes. The cis-9,trans-11 CLA isomer, the predominant isomer in ruminant-derived products, was reported to induce apoptosis of cancer cells. Determining the mechanism of action of CLA will improve our understanding of body fat regulation.

Influence Of Implant Regimen On Performance And Carcass Characteristics In Feedlot Steers, Heather L. Haugen, Galen E. Erickson, Court G. Campbell, Casey G. Macken Jan 2004

Influence Of Implant Regimen On Performance And Carcass Characteristics In Feedlot Steers, Heather L. Haugen, Galen E. Erickson, Court G. Campbell, Casey G. Macken

Nebraska Beef Cattle Reports

A feedlot experiment was conducted to evaluate initial and terminal implant combinations in finishing steers. Implant strategies including Synovex Choice increased average daily gain and rib eye area when compared to strategies including Revalor-IS. Steers implanted initially and terminally with Synovex Choice also had increased performance compared to steers implanted initially and terminally with Revalor-IS; however, performance was not different when comparing Synovex Choice verses Revelor-IS as an initial implant (Revalor-S terminal implant). Marbling was similar across implant strategies, indicating the observed increase in performance with Synovex Choice was achieved without negatively influencing carcass quality.

The Influence Of Corn Kernel Traits On Feedlot Cattle Performance, Stephanie L. Jaeger, Casey N. Macken, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian, David S. Jackson Jan 2004

The Influence Of Corn Kernel Traits On Feedlot Cattle Performance, Stephanie L. Jaeger, Casey N. Macken, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian, David S. Jackson

Nebraska Beef Cattle Reports

Seven commercially available corn hybrids representing a range within and among kernel traits were used in a finishing trial to evaluate effects of corn kernel traits on feedlot animal performance. Average daily gain, DMI, and hot carcass weight were similar among all corn hybrids. A significant difference in feed conversion of 8.4% from lowest to highest among hybrids was observed. Kernel traits correlated with feed conversion were 1,000 grain weight, stenvert time to grind, and stenvert proportion of soft to coarse particles. Efficiency of finishing cattle gain can be significantly improved by selection of corn hybrids with more desirable kernel …

Effect Of Distillers Grains Or Corn Supplementation Frequency On Forage Intake And Digestibility, Tim W. Loy, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson Jan 2004

Effect Of Distillers Grains Or Corn Supplementation Frequency On Forage Intake And Digestibility, Tim W. Loy, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Ten ruminally cannulated heifers received no supplement, dry distillers grains (DDG) daily, DDG on alternating days, dry rolled corn daily, or corn on alternating days. Hay intake was higher for non-supplemented than for supplemented heifers. No intake differences were observed between DDG and corn-supplemented heifers. Heifers supplemented daily had higher and more consistent intakes than those in alternate-day treatments, particularly within corn-supplemented heifers. Ruminal pH and hay fiber disappearance were greater in non-supplemented heifers. Corn-supplemented heifers had slower rates of fiber disappearance than DDG-supplemented. Alternate-day energy supplementation increased intake variability compared to daily supplementation.

Dried Distillers Grains As A Grazed Forage Supplement, James C. Macdonald, Terry J. Klopfenstein Jan 2004

Dried Distillers Grains As A Grazed Forage Supplement, James C. Macdonald, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Thirty heifers grazing smooth bromegrass were individually supplemented with 0, 1.0, 2.1, 3.1, or 4.2 lb per head per day (DM) dried distillers grains (DDG) for 84 days to determine effects of DDG supplementation on ADG and forage intake and to determine the value of DDG in grazing enterprises. Forage intake was estimated using the 1996 NRC model. Supplementation of DDG resulted in a linear increase in ADG and decreased estimated forage intake. DDG may be an attractive forage supplement due to increased revenue from additional ADG and savings from decreased forage intake.

Prediction Of Net Energy Adjuster For Feedlot Cattle When Using The 1996 Beef Cattle Nrc Model, Casey N. Macken, Rob J. Cooper, Terry J. Klopfenstein, Galen E. Erickson Jan 2004

Prediction Of Net Energy Adjuster For Feedlot Cattle When Using The 1996 Beef Cattle Nrc Model, Casey N. Macken, Rob J. Cooper, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Data from 277 treatment means in 15 previous beef cattle studies were used to develop equations to predict net energy adjusters throughout the feeding period to better predict gain with the National Research Council’s 1996 Nutrient Requirements of Beef Cattle model. Early in the feeding period the net energy adjuster reduces the energy to correct for overprediction of gain and late in the feeding period the net energy adjuster increases energy to correct for under prediction of gain. The average NE adjusters were 0.88 and 1.08 for the beginning and end of the feeding period.

Feed Values For Annual Forages In Western Nebraska, Burton A. Weichenthal, David D. Baltensperger, Kenneth P. Vogel Jan 2004

Feed Values For Annual Forages In Western Nebraska, Burton A. Weichenthal, David D. Baltensperger, Kenneth P. Vogel

Nebraska Beef Cattle Reports

Forage quality testing was completed on annual forages grown during 1998 and/or 1999. Included were spring cereals, legumes and summer annuals like sorghum and millets. Using a single cut harvest system when the majority of summer annuals had produced seed heads, crude protein (CP) was generally more than 8% and total digestible nutrients (TDN) more than 63% of dry matter. Annual legumes had 12 to 18% CP and more than 63% TDN. Pearl and irrigated foxtail millets had higher crude protein levels than sorghum forages, but nitrate levels were also higher. Some mineral contents varied by location and associated management.

Loose Not The Floodgates, Benjamin J. Cooper Jan 2004

Loose Not The Floodgates, Benjamin J. Cooper

Cardozo Journal of Equal Rights & Social Justice

The article examines the implications of the Supreme Court's decision in Lawrence v. Texas, which struck down sodomy laws, arguing that while the ruling was necessary, it raises concerns about the broader regulation of sexual conduct outside marriage. The author contends that such laws, despite rare enforcement, serve societal functions, including protecting marriage and providing moral boundaries that deter harmful behavior, particularly among young people.

Lawrence V. Texas: When "Profound And Deep Convictions" Collide With Liberty Interests, Nancy J. Knauer Jan 2004

Lawrence V. Texas: When "Profound And Deep Convictions" Collide With Liberty Interests, Nancy J. Knauer

Cardozo Journal of Equal Rights & Social Justice

The article examines the Supreme Court's landmark decision in Lawrence v. Texas, which overturned Bowers v. Hardwick and invalidated a Texas sodomy law criminalizing same-sex intimacy. The author argues that Lawrence not only advanced individual liberty interests but also marked a significant shift in the legal and cultural recognition of homosexuality, moving beyond earlier frameworks that criminalized or marginalized gay individuals. The decision reflects broader societal changes in understanding same-sex relationships and challenges the use of moral disapproval as a basis for legal restrictions on consensual adult conduct.

The Missing Word In Lawrence V. Texas, Ruthann Robson Jan 2004

The Missing Word In Lawrence V. Texas, Ruthann Robson

Cardozo Journal of Equal Rights & Social Justice

The article critiques the Supreme Court's decision in Lawrence v. Texas for omitting a crucial acknowledgment: an apology for the harm caused by its previous ruling in Bowers v. Hardwick. While Lawrence overturned the unconstitutional sodomy law, the Court's opinion neglected to address the profound suffering and discrimination endured by LGBTQ+ individuals due to *Bowers*. The author argues that an apology is essential to acknowledge the pain inflicted and to provide closure for those affected.

A Prisoner's Right To Transsexual Therapies: A Look At Brooks V. Berg, Linda D. Chin Jan 2004

A Prisoner's Right To Transsexual Therapies: A Look At Brooks V. Berg, Linda D. Chin

Cardozo Journal of Equal Rights & Social Justice

The note examines the legal and ethical implications of providing medical treatment, particularly gender reassignment surgery (GRS), to transgender prisoners under the Eighth Amendment, which prohibits cruel and unusual punishment. It argues that while courts have recognized the necessity of addressing gender dysphoria, the financial and logistical challenges of providing such treatments raise concerns about equity and resource allocation. The ruling in Brooks v. Berg highlights the tension between constitutional rights and the practical limitations of prison systems in meeting these needs.

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier Jan 2004

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier

LSU Doctoral Dissertations

The late modern and postmodern theme of homecoming permeates the philosophy of Martin Heidegger, who grapples with the topic throughout the various phases of his lifelong meditation on Being. Heidegger continually gave thought to the relationship between Being and the place or site in which it becomes manifest, whether it is a system of references and manipulable entities (Being and Time), language (An Introduction to Metaphysics), or aesthetic works of art (“The Origin of the Work of Art”). Taking as its point of departure Heidegger’s persistent and dynamic search for home (Heimat), this study will examine the political implications of …

Investigations Into Dna Vaccination Against Channel Catfish Virus, Heather C. Harbottle Jan 2004

Investigations Into Dna Vaccination Against Channel Catfish Virus, Heather C. Harbottle

LSU Doctoral Dissertations

The leading viral killer of commercially produced channel catfish is Channel Catfish Virus (CCV). Studies conducted to evaluate DNA vaccination against CCV compared encoded gene, dose, multiple DNA vaccines, and immune response to vaccination. Genes were selected (ORFs 1 and 3 [immediate early genes], ORFs 6, 19, and 46 [membrane genes], and ORF59 [putative major envelope glycoprotein gene], cloned into a plasmid, and expressed in mammalian and fish cell culture to detect predicted molecular weight proteins. Plasmid vaccines were injected into fish muscle in doses of 50 μg, 25 μg, 5 μg, or 1 μg and efficacy was evaluated upon …

Soils Of Regeneration: Exploring Conceptualizations Of The Natural World As A Context For An Ecologically-Sensitive Curriculum, Emily A. Demoor Jan 2004

Soils Of Regeneration: Exploring Conceptualizations Of The Natural World As A Context For An Ecologically-Sensitive Curriculum, Emily A. Demoor

LSU Doctoral Dissertations

David Orr (1994) asserts that the ecological crisis is a crisis of education. This study explores the relationship between the ecological crisis and education by examining the role that language plays in shaping perceptions of the natural world. Toward this end it analyzes narratives of science, literature and other disciplines that conceptualize the natural world as object and as subject. It evaluates how particular metaphors used in reference to the natural world enhance or impede ecological understanding and the cultivation of responsibility and stewardship and considers ways in which these conceptualizations might be used as a basis for new curriculum …

Activity-Based Anorexia: The Effects Of Resistant Starch, Holly M. Nguyen Jan 2004

Activity-Based Anorexia: The Effects Of Resistant Starch, Holly M. Nguyen

LSU Master's Theses

Anorexia nervosa is the third most common illness among adolescent females. Approximately one half the cases of anorexia nervosa have been suggested to be activity-induced. Various animal studies have been used to study human anorexia, particularly the activity-based anorexia model (ABA). The ABA paradigm consists of diet restriction and liberal access to activity, which ultimately results in a rapid decrease in both body weight and food intake paradoxical to the significant increase in activity. Because resistant starch (RS) has been shown to initiate a lower rise and a steady level of post-prandial blood glucose, it was hypothesized that a diet …

American Verismo?: Insights Into The Padrone, And Opera By George Whitefield Chadwick (13 November 1854 - 4 April 1931), Jon Steffen Truitt Jan 2004

American Verismo?: Insights Into The Padrone, And Opera By George Whitefield Chadwick (13 November 1854 - 4 April 1931), Jon Steffen Truitt

LSU Doctoral Dissertations

The contribution of George Whitefield Chadwick (13 November 1854 – 4 April 1931) to American music comes in many forms: composer, teacher, conductor, pianist and organist. A leading figure of the Second School of New England composers, Chadwick was also largely responsible for the effective reorganization of the New England Conservatory. He was arguably one of the most influential teachers in American music in the latter half of the nineteenth century and the beginning of the twentieth century. This study deals with Chadwick’s last opera intended for professional production, The Padrone. The opera, an American example of Italian verismo, is …

Freshwater And Nutrient Inputs To A Mississippi River Deltaic Estuary With River Re-Introduction, Emily Christina Grace Hyfield Jan 2004

Freshwater And Nutrient Inputs To A Mississippi River Deltaic Estuary With River Re-Introduction, Emily Christina Grace Hyfield

LSU Master's Theses

In this study, I quantified freshwater and nutrient inputs in the Breton Sound estuary which is receiving freshwater reintroduction in an effort to restore deteriorating wetlands. Almost all wetlands of the Mississippi deltaic plain are isolated from riverine input due to flood control levees along the Mississippi River. This has altered water and nutrient budgets and is a primary cause of the massive wetland loss in the delta. Maintenance of the delta depends on a healthy, functioning ecosystem which includes riverine input. The Breton Sound estuary is located southeast of New Orleans and until recently was hydrologically isolated from direct …

Developing Embryo Technologies For The Eland Antelope (Taurotragus Oryx), Gemechu G. Wirtu Jan 2004

Developing Embryo Technologies For The Eland Antelope (Taurotragus Oryx), Gemechu G. Wirtu

LSU Doctoral Dissertations

Assisted reproductive technologies developed in domestic cattle serve as a starting point in similar studies on nondomestic bovids. The common eland is a useful model species for studies on rare tragelaphine antelopes. In Chapter 3 of the present study, effects of components/attributes of protein-free embryo culture media on the in vitro development of in vitro-derived bovine embryos were evaluated. A 2 x 2 factorial study comparing effects of groups of amino acids (20aa or 11aa) in two base media (modified KSOM or BM-3) demonstrated that amino acids and base medium affected embryonic development. A subsequent 7 x 2 factorial experiment …
