Feed Management Practices To Reduce Manure Phosphorus Excretion In Dairy Cattle, E. Kebreab, A. V. Hansen, B. Leytem Jan 2013

Feed Management Practices To Reduce Manure Phosphorus Excretion In Dairy Cattle, E. Kebreab, A. V. Hansen, B. Leytem

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Phosphorus (P) is an essential mineral that needs to be supplied in sufficient quantities for maintenance and growth and milk production in dairy cattle. However, over 60% of the P consumed can be excreted in faeces with a potential to cause environmental pollution. Concern over higher levels of P in intensively managed livestock systems has led to legislation such as the Water Framework Directive in the European Union. In this manuscript, several methods of reducing P pollution are discussed. A major source of environmental P pollution has been overfeeding P mainly due to addition of ‘safety margin’ over the animal’s …

Climate Change Reduces The Net Sink Of Ch4 And N2O In A Semiarid Grassland, Feike A. Dijkstra, Jack A. Morgan, Ronald F. Follett, Daniel R. Lecain Jan 2013

Climate Change Reduces The Net Sink Of Ch4 And N2O In A Semiarid Grassland, Feike A. Dijkstra, Jack A. Morgan, Ronald F. Follett, Daniel R. Lecain

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Atmospheric concentrations of methane (CH4) and nitrous oxide (N2O) have increased over the last 150 years because of human activity. Soils are important sources and sinks of both potent greenhouse gases where their production and consumption are largely regulated by biological processes. Climate change could alter these processes thereby affecting both rate and direction of their exchange with the atmosphere. We examined how a rise in atmospheric CO2 and temperature affected CH4 and N2O fluxes in a well-drained upland soil (volumetric water content ranging between 6% and 23%) in a semiarid grassland …

When Tigers Bare Teeth: A Qualitative Study Of University Patent Enforcement, Jacob H. Rooksby Jan 2013

When Tigers Bare Teeth: A Qualitative Study Of University Patent Enforcement, Jacob H. Rooksby

Law Faculty Publications

The pursuit of patents is a key avenue of economic development and revenue generation for American research universities, and one with significant policy implications for higher education. In a time of shifting funding models for higher education, the $1.8 billion dollars American universities generated in revenues in 2011 from licensing their patents makes patenting an attractive candidate for further university attention and resource investment. Spurred in part by the Bayh-Dole Act of 1980, research universities across the country have created vast institutional  apparatuses—typically centered in technology transfer offices (“TTOs”)—to help move ideas invented in the laboratory and classroom into commercial …

The Virtues Of Thinking Small, Corinna Barrett Lain Jan 2013

The Virtues Of Thinking Small, Corinna Barrett Lain

Law Faculty Publications

Professor Lain argues that, in efforts to determine how close American states are to abolishing the death penalty, scholars should "think small," examining the ground level issues that affect its imposition. Among the issues she explores are exonerations of defendants, the legality and obtainability of lethal injection drugs, and the high costs of seeking and imposing capital punishment.

Race And Racism In Internet Studies: A Review And Critique, Jessie Daniels Jan 2013

Race And Racism In Internet Studies: A Review And Critique, Jessie Daniels

Publications and Research

Race and racism persist online in ways that are both new and unique to the Internet, alongside vestiges of centuries-old forms that reverberate significantly both offline and on. As we mark 15 years into the field of Internet studies, it becomes necessary to assess what the extant research tells us about race and racism. This paper provides an analysis of the literature on race and racism in Internet studies in the broad areas of (1) race and the structure of the Internet, (2) race and racism matters in what we do online, and (3) race, social control and Internet law. …

Using Design Experiments To Conduct Research On Mathematics Professional Development, Paola Sztajn, Holt Wilson, Cyndi Edgington, M Myers, Lara Dick Jan 2013

Using Design Experiments To Conduct Research On Mathematics Professional Development, Paola Sztajn, Holt Wilson, Cyndi Edgington, M Myers, Lara Dick

Faculty Journal Articles

In this paper, we propose that the emerging transformation of mathematics professional development from a practice-based to a research field would benefit from stronger connections to research on learning. In particular, we contend that design experiments represent a premier emerging methodology to study learning, and we argue that a better understanding of teacher learning through the use of design experiments in mathematics professional development can lead to improvement of mathematics professional development as both an area of practice and a field of research.

Phenology-Assisted Classification Of C3 And C4 Grasses In The U.S. Great Plains And Their Climate Dependency With Modis Time Series, Cuizhen Wang, E. Raymond Hunt Jr., Li Zhang, Huadong Guo Jan 2013

Phenology-Assisted Classification Of C3 And C4 Grasses In The U.S. Great Plains And Their Climate Dependency With Modis Time Series, Cuizhen Wang, E. Raymond Hunt Jr., Li Zhang, Huadong Guo

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Grassland ecosystems in the North America are primarily composed of C3 and C4 plant functional types (PFTs) that have different responses to the changing climate. Knowledge of their spatial distributions and temporal var- iations helps us better understand the ecological functions and climate dependencies of grasslands. This study used the 500-m MODIS surface reflectance products (MOD09A1) from 2000 to 2009 to extract NDVI time series of C3 and C4 grass PFTs in different floristic regions (tallgrass, shortgrass, and mixed-grass prairies.) A set of phe- nology metrics, including Start of Season, End of Season, Season Length, Peak NDVI, Peak Date, and …

Rats Acquire Stronger Preference For Flavors Consumed Towards The End Of A High-Fat Meal, Kevin P. Myers Jan 2013

Rats Acquire Stronger Preference For Flavors Consumed Towards The End Of A High-Fat Meal, Kevin P. Myers

Faculty Journal Articles

Rats learn to prefer flavors associated with postingestive effects of nutrients. The physiological signals underlying this postingestive reward are unknown. We have previously shown that rats readily learn to prefer a flavor that was consumed early in a multi-flavored meal when glucose is infused intragastrically (IG), suggesting rapid postingestive reward onset. The present experiments investigate the timing of postingestive fat reward, by providing distinctive flavors in the first and second halves of meals accompanied by IG fat infusion. Learning stronger preference for the earlier or later flavor would indicate when the rewarding postingestive effects are sensed. Rats consumed sweetened, calorically-dilute …

Common Parietal Activation In Musical Mental Transformations Across Pitch And Time, Nicholas E.V. Foster, Andrea R. Halpern, Robert J. Zatorre Jan 2013

Common Parietal Activation In Musical Mental Transformations Across Pitch And Time, Nicholas E.V. Foster, Andrea R. Halpern, Robert J. Zatorre

Faculty Journal Articles

We previously observed that mental manipulation of the pitch level or temporal organization of melodies results in functional activation in the human intraparietal sulcus (IPS), a region also associated with visuospatial transformation and numerical calculation. Two outstanding questions about these musical transformations are whether pitch and time depend on separate or common processing in IPS, and whether IPS recruitment in melodic tasks varies depending upon the degree of transformation required (as it does in mental rotation). In the present study we sought to answer these questions by applying functional magnetic resonance imaging while musicians performed closely matched mental transposition (pitch …

Structure And Thermodynamics Of H3o+(H2o)8 Clusters: A Combined Molecular Dynamics And Quantum Mechanics Approach, Berhane Temelso, Thorsten Koddermann, Karl K. Kirschner, Katurah L. Klein, George C. Shields Jan 2013

Structure And Thermodynamics Of H3o+(H2o)8 Clusters: A Combined Molecular Dynamics And Quantum Mechanics Approach, Berhane Temelso, Thorsten Koddermann, Karl K. Kirschner, Katurah L. Klein, George C. Shields

Faculty Journal Articles

We have studied the structure and stability of (H3O+)(H2O)8 clusters using a combination of molecular dynamics sampling and high-level ab initio calculations. 20 distinct oxygen frameworks are found within 2 kcal/mol of the electronic or standard Gibbs free energy minimum. The impact of quantum zero-point vibrational corrections on the relative stability of these isomers is quite significant. The box-like isomers are favored in terms of electronic energy, but with the inclusion of zero-point vibrational corrections and entropic effects tree-like isomers are favored at higher temperatures. Under conditions from 0 to 298.15 K, the …

Capuchin Monkeys Exercise Self-Control By Choosing Token Exchange Over An Immediate Reward, Peter G. Judge, Jennifer L. Essler Jan 2013

Capuchin Monkeys Exercise Self-Control By Choosing Token Exchange Over An Immediate Reward, Peter G. Judge, Jennifer L. Essler

Faculty Journal Articles

Self-control is a prerequisite for complex cognitive processes such as cooperation and planning. As such, comparative studies of self-control may help elucidate the evolutionary origin of these capacities. A variety of methods have been developed to test for self-control in non-human primates that include some variation of foregoing an immediate reward in order to gain a more favorable reward. We used a token exchange paradigm to test for self-control in capuchin monkeys (Cebus apella). Animals were trained that particular tokens could be exchanged for food items worth different values. To test for self-control, a monkey was provided with …

Secondary Collisions Revisited: Real-World Crash Data And Relationship To Crash Test Criteria, Randall C. Gowat, Douglas J. Gabauer Jan 2013

Secondary Collisions Revisited: Real-World Crash Data And Relationship To Crash Test Criteria, Randall C. Gowat, Douglas J. Gabauer

Faculty Journal Articles

Objectives: Previous research conducted in the late 1980s suggested that vehicle impacts following an initial barrier collision increase severe occupant injury risk. Now over 25years old, the data are no longer representative of the currently installed barriers or the present US vehicle fleet. The purpose of this study is to provide a present-day assessment of secondary collisions and to determine if current full-scale barrier crash testing criteria provide an indication of secondary collision risk for real-world barrier crashes. Methods: To characterize secondary collisions, 1,363 (596,331 weighted) real-world barrier midsection impacts selected from 13years (1997-2009) of in-depth crash data available through …

Relating Climate Change To The Nesting Phenology And Nest Environment Of Marine Turtles, Monette Schwoerer Jan 2013

Relating Climate Change To The Nesting Phenology And Nest Environment Of Marine Turtles, Monette Schwoerer

Electronic Theses and Dissertations

Ectotherms (including marine turtles) being especially sensitive to climate, are at risk to the accelerated rate of human-driven climate change. This study addresses two concerns associated with marine turtles and climate change – the relationship between the timing of marine turtle nesting and sea surface temperature; and the concern over the feminization of marine turtle populations due to rising sand temperatures. Previous studies of loggerhead sea turtles (Caretta caretta) and green sea turtles (Chelonia mydas) have documented the relationship between sea surface temperatures and nesting phenology. Earlier nesting behaviors in both species have been associated with warmer sea surface temperatures. …

Twentieth Century Maya Worldview, Mackenzie See Jan 2013

Twentieth Century Maya Worldview, Mackenzie See

Electronic Theses and Dissertations

Maya Folktales offer insight into how twentieth century Maya worldview is a hybrid of indigenous Maya and European beliefs. Analysis was conducted on twenty-eight Maya folktales from the highlands of Guatemala found in folklore anthologies. Stories like The Spirits of the Dead in folklore anthologies can reveal new perspectives on how the Maya feel about rituals spaces, the fabric that separates the land of the dead from the land of the living, and the importance of showing respect to the dead in one’s community. Other stories, show the connection the Maya feel with their heritage and the connection they feel …

Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali Jan 2013

Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali

Electronic Theses and Dissertations

Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …

Which Way To The Jook Joint?: Historical Archaeology Of A Polk County, Florida Turpentine Camp, Deborah Ziel Jan 2013

Which Way To The Jook Joint?: Historical Archaeology Of A Polk County, Florida Turpentine Camp, Deborah Ziel

Electronic Theses and Dissertations

The extraction and distillation of pine sap for the naval stores industry reached its apex of production in the early decades of the twentieth century. Post-emancipation, the industry employed African American labor in the long leaf pine forests of the southeastern United States under a system of debt peonage that replaced the master-slave dynamic with a similar circumscriptive construct. Laborers rented company housing and were paid in scrip, a monetary system that limited their purchase of the basic goods of subsistence to the company commissary at inflated prices, resulting in an endless cycle of debt. Despite the oppressive circumstances of …

Socratic Metaphysics, William J. Prior Jan 2013

Socratic Metaphysics, William J. Prior

Philosophy

Did Socrates have a metaphysics? The question is complex. We might begin by asking, what is a metaphysics? We might also ask, who we mean by Socrates? Let me deal with these questions in order. Metaphysics is concerned with what lies at the foundation of things, the principles underlying reality. ln this essay, that will mean primarily an ontology, a theory of 'what there is'. Now one point on which the authors discussed in this article agree, a 'point of departure' that anchors their various views about Socratic metaphysics, is that Plato had a metaphysics: as Gregory Vlastos puts it, …

Efficient Extraction Method To Collect Sugar From Sweet Sorghum, Fei Jia, Jeerwan Chawhuaymak, Mark R. Riley, Werner Zimmt, Kimberly L. Ogden Jan 2013

Efficient Extraction Method To Collect Sugar From Sweet Sorghum, Fei Jia, Jeerwan Chawhuaymak, Mark R. Riley, Werner Zimmt, Kimberly L. Ogden

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: Sweet sorghum is a domesticated grass containing a sugar-rich juice that can be readily utilized for ethanol production. Most of the sugar is stored inside the cells of the stalk tissue and can be difficult to release, a necessary step before conventional fermentation. While this crop holds much promise as an arid land sugar source for biofuel production, a number of challenges must be overcome. One lies in the inherent labile nature of the sugars in the stalks leading to a short usable storage time. Also, collection of sugars from the sweet sorghum stalks is usually accomplished by …

Meme World Syndrome: A Critical Discourse Analysis Of The First World Problems And Third World Success Internet Memes, Robert Chandler Jan 2013

Meme World Syndrome: A Critical Discourse Analysis Of The First World Problems And Third World Success Internet Memes, Robert Chandler

Electronic Theses and Dissertations

This thesis applies the theory and method of Critical Discourse Analysis (CDA) to examine the ideological components of the First World Problems (FWP) and Third World Success (TWS) Internet memes. Drawing on analytical concepts from CDA and related perspectives, such as multimodal discourse analysis and social semiotics, the paper analyzes the visual and textual elements of a sample of the FWP and TWS memes. The paper argues that the text and images featured in the memes are ideologically salient and discursively construct oppositional binaries between “us” and “them” in terms of wealth disparity.
