Optimal Marketing Date Of Steers Depends On Marketing Strategy, James C. Macdonald, Cody J. Schneider, Kelsey M. Rolfe Rolfe, Stephen D. Kachman, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Seven research trials conducted over five years at the University of Nebraska–Lincoln were summarized to determine how animal performance changes through the finishing period on a live and carcass weight basis. Live weight, carcass weight, carcass ADG, and carcass feed efficiency all changed quadratically throughout the feeding period; live ADG and live feed efficiency declined linearly. During times of negative profit margins, optimal profitability for steers marketed on a live-basis occurred by selling early, whereas optimal profitability was achieved by feeding steers marketed on a carcass-basis longer.

The Effects Of Diet And Cooler Aging On Specific Flavor Notes In Beef, Kimberly A. Varnold, Chris R. Calkins, Rhonda K. Miller Miller, Galen E. Erickson

Nebraska Beef Cattle Reports

Crossbred steers (n = 64) were grazed on warm- or cool-season grass-dominated pastures, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Finishing on corn increased desirable flavor notes and decreasedundesirable flavor notes in both L. dorsi and B. femoris steaks. In addition, grazing on warm-season grasses increased the prevalence of undesirable flavors but was often dissipated by the addition WDGS supplementation. Longer aging periods tended to increase the prevalence of undesirable flavors, especially in B. femoris steaks. It is recommended producers provide WDGS supplementation, …

Water Resources And The Historic Wells Of Barbuda: Tradition, Heritage And Hope For A Sustainable Future, Rebecca Boger, Sophia Perdikaris, Amy E. Potter, John Mussington, Reginald Murphy, Louise Thomas, Calvin Gore, Dwight Finch

Department of Anthropology: Faculty Publications

The island of Barbuda has a relatively unique history, land tenure and geography. Unlike its Caribbean counterparts, the island is not suited to large-scale agriculture due to its arid climate and relatively thin soils. Instead, the enslaved and eventually free people of Barbuda developed a complex herding ecology centered on common land ownership. As a result, carefully designed historic wells are strategically located around the island. With the challenges brought about by climate change, an interdisciplinary, international team led by the Barbuda Research Complex is investigating the state of existing water and food resources and examining how the availability and …

Eye Of The Needle: Cold Stress, Clothing, And Sewing Technology During The Younger Dryas Cold Event In North America, Alan J. Osborn

Department of Anthropology: Faculty Publications

This paper examines the possible underlying systemic context(s) for spurred flake gravers and eyed bone needles recovered from Paleoindian sites in North America. The idea that spurred flake gravers and eyed bone needles were closely associated is not new. Archaeologists in both Eurasia and North America have also proposed that eyed bone and ivory needles were used for manufacturing tailored skin clothing. It is suggested here that spurred flake gravers and eyed bone needles may, in fact, be the material correlates of critical non-subsistence related work carried out by women to meet the challenges of very severe winters and cold …

Cyanobacteria Harmful Algal Blooms In South Louisiana Estuaries : A Synthesis Of Field Research, Management Implications, And Outreach, Emily Anne Smith

LSU Doctoral Dissertations

Estuaries are biologically productive and important habitats for several fisheries. However, human intervention has separated many estuaries from their needed freshwater source and the commonly used solution is to use diversions to regulate the flow. This episodic increase in nutrients into estuaries has sometimes led to the formation of freshwater cyanobacteria HABs (CyanoHABs). The goal of this dissertation was to look at a field research study of phytoplankton bloom dynamics; management implications for cyanobacteria entering estuaries; and an outreach effort in relation to residents knowledge about cyanobacteria and algae. The first study compared the phytoplankton bloom dynamics, specifically CyanoHABs, in …

Adult Offender Recidivism Rates: How Effective Is Pre-Release And Vocational Education Programing And What Demographic Factors Contribute To An Offenders Return To Prison, James K. Bueche, Jr.

LSU Doctoral Dissertations

The primary purpose of this study was to determine if the Louisiana Department of Public Safety and Corrections’ 100 hour pre-release program and vocational education had a significant impact on offender recidivism. Additionally, a model of predicating offender recidivism using demographic data was another aspect of the study. Offenders in the study were 404 offenders who completed the pre-release program, 404 offenders who completed vocational education and 808 offenders who composed the control group. All offenders were released from prison in the year of 2010, and if they returned to prison between their release and December 31, 2013, they were …

Heidegger, Metaphor, And The Essence Of Language, Joel Meservy

LSU Master's Theses

In this thesis, I address the question of Heidegger’s rejection of metaphor, alleging most of the commentary on this rejection has failed to confront its substance. In particular, I focus on two different interpretations, one given by Paul Ricoeur and the other by Jacques Derrida. Both of these accounts place Heidegger’s rejection in a model of language structured by the sign relation; however, I contend Heidegger rejects metaphor precisely in order to overcome this model of language. Heidegger's few references to metaphor occur within attempts to rethink the very nature of our being-in-the-world and our relationship to language; that is, …

Species Composition And Spatial Ecology Of Amazonian Understory Mixed-Species Flocks In A Fragmented Landscape, Karl Mokross

LSU Doctoral Dissertations

With the ongoing advance of the agricultural frontier in the Amazon basin, it is inevitable that heterogeneous landscapes will play a key role in conservation. These landscapes are mostly composed of patchworks of small forest fragments, secondary forests and roads. Conservation, however must take species interactions into consideration as they play a pivotal part the maintenance of several biological processes in the tropics. One of the most conspicuous interspecific interactions are seen in mixed-species flocks of birds, which in the Amazon, represent one of the best organized systems of bird aggregations. In this research, I assess how flock spatial behavior …

The Effect Of Modifying The Higher-Order Structure Of Plant High-Affinity Phosphate Transporters, Elena Batista Fontenot

LSU Doctoral Dissertations

Phosphorus is an essential nutrient taken up by plants in the form of phosphate and is a component of key molecules, such as ATP, DNA, and RNA, and is one of the most frequently limiting macronutrients for plant growth. More than 80 % of phosphorus found in soil exists as non-inorganic forms and is unavailable for plant uptake, demonstrating the importance for genes induced to cope with phosphate starvation, including high-affinity phosphate transporters (Phts). Phts are membrane-localized transporters involved in the transport of phosphate and arsenate and have a high capacity for transporting phosphate in areas where phosphate concentrations are …

Between Nihilism And Transcendence : Albert Camus' Dialogue With Nietzsche And Dostoevsky, Sean Derek Illing

LSU Doctoral Dissertations

This dissertation examines the impact of Fyodor Dostoevsky and Friedrich Nietzsche on the development of Albert Camus’ political philosophy. The innovation of the present study is in the attempt to offer a substantive examination of Camus’ dialogue with Nietzsche and Dostoevsky. To the extent that connections between these writers have been discussed, it has been in the general context of modern thought or it has focused on overlapping literary themes. This project emphasizes the political dimensions of these connections. In addition to re-interpreting Camus’ political thought, the aim is to clarify Camus’ struggle with transcendence and to bring renewed attention …

Suburban Sustainability: Favorable, Forgotten, Or Fantasy?, Tessia Melvin, Tessia G. Melvin

School of Business Student Theses and Dissertations

In the decades after World War II, the United States became a prosperous nation and world superpower. Reinventing itself through the development of suburbs, many communities were created by suburbs. Years later, criticized for suburban sprawl and aging communities, suburban communities today are faced with the dilemma of what changes to make in order to create sustainable suburban communities.

Most of the literature on sustainability and its success comes from the private sector. Much available literature provides sustainable indicators and concepts on corporate sustainability. As a result, many public administrators are faced with a reality that changes need to occur …

Suspense, Structure, And Point Of View: Building Surprise In Fiction, Lydia R. Klismith

Departmental Honors Projects

Suspense, Structure, and Point of View: Building Surprise in Fiction is focused on what elements authors can use to create surprise. Surprise relies primarily on suspense in order to function. Broadly, structure and point of view are the two categories of tools an author will rely on to create suspense and build surprise. Examining various texts, this paper outlines many possible routs an author can take to support the surprise of his or her text. In my creative component I rely on the alternating point of view chapters in order to create suspense and eventually surprise. Malachi and Eve observe …

Finding The Witch’S Mark: Female Participation In The Judicial System During The Hopkins Trials 1645-47, Shannon M. Lundquist

Departmental Honors Projects

Between the years of 1645 and 1647 in East Anglia, a series of witch trials known as the Hopkins Trials took place. In all, 250 witches were accused and 100 hanged. The ability to convict a person of the crime of witchcraft relied heavily on evidence which was hard to come by given the nature of the crime of witchcraft. Tangible proof of an intangible crime was needed; this came in the form of witch’s marks. To the learned population, marks were a symbol of the witch’s covenant with the devil. To the lay person, they were called ‘teats’ and …

Freedom Of The Press In Cuba From 2002-2013: Voices Of Post-Revolutionary Exiled Cuban Journalists, Writers And Dissidents In The U.S., Karen E. Anaya

Departmental Honors Projects

The role of media in any society is determined by the level of press freedom in that society. Freedom of the press can be best seen in the relationship between the government and mass media institutions. Since the end of the Cuban Revolution in 1959, the Cuban regime has been criticized by organizations all over the world for allegedly limiting press freedom in the island. Despite the wide controversy, little is known about the state of freedom of the press in Cuban media in the last few years. This study set out to investigate the level of press freedom enjoyed …

Influence Of Aedes Aegypti Saliva On The Vertebrate Host Response To Dengue Virus, Michael Kevin Mccracken

LSU Doctoral Dissertations

Dengue virus (DENV) is maintained in a primarily anthroponotic cycle between humans and the mosquito, Aedes aegypti. Investigations into DENV infection of the vertebrate host generally do not account for the contribution of vector saliva, an inherent part of the mosquito-borne viral inoculum. Feeding by mosquitoes on vertebrate hosts is initiated by probing, which results in physical damage to the skin and vasculature, and the simultaneous introduction of DENV and saliva into the skin. Saliva contains many individual proteins with the potential to modulate host hemostasis and immune responses, thereby facilitating blood feeding and virus transmission. As exogenous antigens, both …

Application Of Choice-Based Conjoint Analysis To Determine Consumers' Preferences And Willingness To Pay For Grass Fed Beef In The United States, Franklin Fernando Vaca Moran

LSU Doctoral Dissertations

U.S. consumption of beef has declined during the last three decades. Consumer preferences have shifted toward products that are considered healthy, environmentally friendly and obtained through sustainable production methods. Because of the characteristics of grass-fed beef production, consumers are becoming more interested in grass-fed beef products than conventional beef products. A choice-based experiment was used to assess consumer’s preferences for grass-fed beef. A national online survey was conducted in May 2012 and the information from 4000 respondents was collected from the entire U.S. The respondents were divided in two groups of similar size: grass-fed beef eaters, comprised by the respondents …

Adaptive Divergence And Speciation Across Depth In A Caribbean Candelabrum Coral, Carlos Andrés Prada Montoya

LSU Doctoral Dissertations

Since Darwin, biologists wonder how organisms cope with environmental variation, why there are so many species, and how species form. In my dissertation, I explore how species of long-lived, clonal reef organisms originate across depth gradients. In Chapter 2, I evaluate the strength of depth to isolate populations by comparing the genes and morphologies of pairs of depth-segregated populations of the candelabrum coral Eunicea flexuosa across the Caribbean. Eunicea flexuosa is a long-lived clonal cnidarian that associates with an alga of the genus Symbiodinium. Genetic analysis revealed two depth-segregated lineages, each genetically well-mixed across the Caribbean. Survivorship data, combined with …

The Effects Of Using Morphophonic Faces As A Method For Teaching Sight Words To Low-Performing Kindergartners, Ashley Alexandra Brown

LSU Master's Theses

Five kindergarten subjects who had no known disabilities, but were identified as low beginning readers received intervention using both Plain Word Cards (PWC) and pictured word cards, termed MorphoPhonic Faces (MPF). A group of eight words were presented as printed word cards and a comparable group of eight words were presented as MPF. Results revealed that MPF did not hold an advantage for learning and retaining sight words compared to the plain print words. Improvements in sight word training corresponded in time with improved skills underlying the alphabetic principle, including phonological awareness skills and letter-sound learning, as well as emerging …

Structural And Kinetic Investigations Of 15-Lipoxygenase-2, Matthew James Kobe

LSU Doctoral Dissertations

Evidence suggests that 15-lipoxygenase-2 (15-LOX-2) plays an important role in the progression of atherosclerosis. Due to the medical need to discover isoform specific inhibitors of 15-LOX-2, a novel human enzyme, our goal was to determine the 3-dimensional structure. Using bacterial expression, we were able to obtain a usable quantity of enzyme with a sufficient amount of the catalytic iron bound to the enzyme, however it was sensitive to cleavage by proteases. This led to a ratio of roughly 1:1 of cleaved and uncleaved protein after the final step of purification. Solving the crystal structure revealed the reason for the protease …

A Mixed Methods Investigation Of Post-Secondary Students' Long Bone Anatomy Knowledge Retention Through Constructivism And The Works Of Vesalius, Jennifer F. Tynes

LSU Doctoral Dissertations

Understanding human long bone anatomy is an important concept to master for post-secondary students that major in medical fields since skeletal structures assist in locating a pulse, conducting clinical procedures, and identifying injection sites. Skeletal anatomy is also used to name structures associated with other organ systems like veins, arteries, and nerves. This explanatory mixed methods study explores post-secondary students’ knowledge retention and perception of various constructivist activities that utilize historical approaches based on the works of Vesalius, the Father of Modern Anatomy to teach long bone anatomy. Three treatment groups and one controlled comparison group (n= 92) were provided …

Enhancement Of Gulf Killifish, Fundulus Grandis, Fitness And Reproduction, Joshua Thomas Patterson

LSU Doctoral Dissertations

Gulf killifish, Fundulus grandis, shows promise for commercial development as a marine baitfish species. Significant markets for F. grandis already exist throughout the Gulf Coast, with the vast majority of supply coming from wild-harvests, which can be hampered by seasonal availability and inconsistent fish health and size. The genus Fundulus also represents an important group of model vertebrates for biological study. A recent review paper described this genus as the premier teleost model for environmental biology. New information generated as a result of the work contained in this dissertation may be more broadly applicable to sister species of F. grandis, …

Residual Effect Of Herbicides Used In Pastures On Clover Establishment And Productivity, Angela Suzanne Laird

LSU Master's Theses

Field experiments in 2013 evaluated residual herbicide effects on ball (Trifolium nigrescens viv.) and white (Trifolium repens L.) clover. For the October planting, averaged across clovers, ground cover for 2,4-D plus aminopyralid and 2,4-D plus picloram averaged 4.4 and was less than for the nontreated (7.0). For the November and March plantings, ground cover for all herbicides was equivalent to the nontreated. Averaged across clover species and planting date, herbicide treatments except 2,4-D plus aminopyralid (4) resulted in ground cover 49/112 days after planting (DAP) equal to the non-treated (5.7). Lowest plant population 4 to 6 wk after Oct/Nov planting …

Three Essays On U.S. Meat Goat Production: Goal Structure, Selection Of Breeding Stock, And Meat Goat Marketing, Narayan Prasad Nyaupane

LSU Doctoral Dissertations

This study investigates three major areas of U.S. meat goat production – goal structure, selection of breeding stock, and marketing, by using survey data received from U.S. meat goat producers. Of 1,600 producers surveyed, 584 usable responses were obtained with an adjusted response rate of 43%. The fuzzy pair-wise comparison method was used to determine producer goal structure. The results showed that profit maximization and leisure-related goals were highly considered goals and controlling weeds/vegetation and increasing farm size were the least considered goals by U.S. meat goat producers. A choice-based conjoint study was conducted to identify producer preferences for meat …

A Contrast Of Hunter Characteristics And Attitudes Between Random And Convenience Samples In The 2010, 2012, And 2013 Surveys Of Louisiana Waterfowl Hunters, Lucien Jr. Paul Laborde

LSU Doctoral Dissertations

I surveyed random (mail and internet panel surveys) and convenience samples (web surveys) of Louisiana waterfowl hunters following the 2009-2010, 2011-2012, and 2012-2013 seasons. I hypothesized significant differences in effort, success, satisfaction and demographics, but no difference in attitudes, in responses between random and convenience survey methods. I mailed to stratified random samples of 2,500 in 2010, 6,400 in 2012, and 2,500 each for mail and on-line internet panel response in 2013. An identical web survey, hosted each year during the same time period, facilitated open-access response. I received 1,676 usable responses in 2010 (727 mail and 949 web), 2,382 …
