Sorghum Flour Characterization And Evaluation In Gluten-Free Flour Tortilla, M. Winger, H. Khouryieh, F. Aramouni, T. Herald

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

Four sorghum hybrids (Fontanelle-625 [F-625]), Fontanelle-1000 [F-1,000], ATx631xRTx2907 [NE#20] and 5,040C) were characterized and evaluated for kernel characteristics, proximate analysis, flour characterization (particle size distributions, starch damage, amylose content and starch pasting properties) and end product in gluten-free tortilla. A commercial sorghum flour (TVM) was used as a control. Significant differences were found (P < 0.05) among hybrids for kernel and flour composition except total starch (P > 0.05). NE#20 had the largest particle diameter for both flour and starch. F-1000 had significantly higher starch damage compared with the other hybrids. Flours with smaller particle size and higher starch damage contributed to softer and more extensible tortilla. Amylose content ranged from 20.2 (NE#20) to …

Grazing Management, Season, And Drought Contributions To Near-Surface Soil Property Dynamics In Semiarid Rangeland, M. A. Liebig, S. L. Kronberg, J. R. Hendrickson, J. R. Gross

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

Grazing management effects on soil property dynamics are poorly understood. A study was conducted to assess effects of grazing management and season on soil property dynamics and greenhouse gas flux within semiarid rangeland. Grazing management treatments evaluated in the study included two permanent pastures differing in stocking rate (moderately and heavily grazed pastures) and a fertilized, heavily grazed crested wheatgrass (Agropyron desertorum [Fisch. ex. Link] Schult.) pasture near Mandan, North Dakota. Over a period of 3 yr, soil properties were measured in the spring, summer, and fall at 0–5 cm and 5–10 cm. Concurrent to soil-based measurements, fluxes of carbon …

Modeling Weather And Stocking Rate Effects On Forage And Steer Production In Northern Mixed-Grass Prairie, Q. X. Fang, A. A. Andales, J. D. Derner, L. R. Ahuja, L. Ma, P. N. S. Bartling, J. L. Reeves, Z. Qi

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

Stocking rate (SR) is the primary management factor that influences livestock gains, plant community changes and forage production, as well as economic returns for livestock producers. More effective stocking decision making by ranchers in the semi-arid northern mixed-grass prairie requires clearly understanding forage production and yearling steer weight gain (SWG) responses to SR and high weather variability. The objectives of this study were to: (1) test the Great Plains Framework for Agricultural Resource Management-Range (GPFARM-Range) model for predicting forage production and SWG under three experimental SR treatments and long-term weather conditions on semiarid northern mixed-grass prairie in southeast Wyoming, USA; …

The Use Of Electromagnetic Induction Techniques In Soils Studies, James A. Doolittle, Eric C. Brevik

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

Electromagnetic induction (EMI) has been used to characterize the spatial variability of soil properties since the late 1970s. Initially used to assess soil salinity, the use of EMI in soil studies has expanded to include:mapping soil types; characterizing soil water content and flow patterns; assessing variations in soil texture, compaction, organicmatter content, and pH; and determining the depth to subsurface horizons, stratigraphic layers or bedrock, among other uses. In all cases the soil property being investigatedmust influence soil apparent electrical conductivity (EC_a) either directly or indirectly for EMI techniques to be effective. An increasing number and diversity of …

Seasonal Weather Influences On Yearling Beef Steer Productionin C3-Dominated Northern Great Plains Rangeland, Justin L. Reeves, Justin D. Derner, Matt A. Sanderson, John R. Hendrickson, Scott L. Kronberg, Mark P. Petersen, Lance T. Vermeire

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

In the face of an increasingly variable climate, long-term cattle weight gain datasets are rare, yet invalu-able, for determining site-specific influences of seasonal weather patterns on cattle production. Here,we present a long-term (1936–2005) yearling Hereford steer dataset collected at the Northern GreatPlains Research Laboratory (NPGRL) near Mandan, ND, USA. Data were analyzed using weighted AICcmodel averaging to examine the effects of spring (April–June) and summer (July–September) temper-ature and precipitation, as well as prior growing season (prior April–September) and prior fall/winter(prior October–March) precipitation on cattle production (kg/ha) under light (37.4 ± 5.3 SD Animal UnitDays [AUD]/ha across all study years) and …

Monitoring Runoff From Cattle-Grazed Pastures For A Phosphorus Loss Quantification Tool, Peter A. Vadas, Dennis L. Busch, J. Mark Powell, Geoff E. Brink

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

Nitrogen (N) and phosphorus (P) loss from agriculture persists as a water quality impairment issue. For dairy farms, nutrients can be lost from cropland, pastures, barnyards, and outdoor cattle lots. We monitored N and P loss in runoff from dairy and beef grazed pastures for two years in southwest Wisconsin, USA and tested the accuracy of the Annual P Loss Estimator (APLE) model to predict runoff P from pastures using study and literature data. About 3–10% of annual precipitation became runoff from the pastures, and sediment loss was very low due to well-established vegetation. Measured annual nutrient loss in runoff …

Exploring Integrated Crop–Livestock Systems In Different Ecoregions Ofthe United States, R. Mark Sulc, Alan J. Franzluebbers

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

Large-scale, energy-intensive, specialized production systems have dominated agricultural production inthe United States for the past half-century. Although highly productive and economically successful, thereis increasing concern with unintended negative environmental impacts of current agricultural systems.Production systems integrating crops and livestock have potential for providing additional ecosystem ser-vices from agriculture by capturing positive ecological interactions and avoiding negative environmentaloutcomes, while sustaining profitability. A diversity of ecologically sound integrated crop-livestock sys-tems have been and can be employed in different ecoregions: sod-based crop rotations, grazing covercrops in cash-crop rotations, crop residue grazing, sod intercropping, dual-purpose cereal crops, and agro-forestry/silvopasture. Improved technologies in conservation tillage, …

Larval Mortality And Development For Rotation-Resistant And Rotation-Susceptible Populations Of Western Corn Rootworm On Bt Corn, N A. Tinsley, J L. Spencer, R E. Estes, J. R. Prasifka, P M. Schrader, B. W. French, M E. Gray

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

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is one of the most economically important insect pests threatening the production of corn, Zea mays (L.), in the United States. Throughout its history, this insect has displayed considerable adaptability by overcoming a variety of pest management tactics, including the cultural practice of annual crop rotation. Since first reported in Illinois in the late 1980s, populations of the rotation-resistant western corn rootworm have spread over a wide area of the eastern Corn Belt. Currently, little information is available concerning the interaction of rotation resistance with the use of genetically modified corn expressing …

From Crisis Pregnancy Centers To Teenbreaks.Com: Anti-Abortion Activism's Use Of Cloaked Websites, Jessie Daniels

Publications and Research

Anti-abortion activists are making use of a deceptive form of propaganda online through cloaked websites that conceal authorship in order to deliberately disguise their political agenda. This deceptive form of online activism is predated and exists alongside another through the use of brick-and-mortar “Crisis Pregnancy Centers.” Anti-abortion, or “pro-life,” activists have long used storefront outposts designated “Crisis Pregnancy Centers” that masquerade as providers of reproductive health services to deceive women who are pregnant into scheduling appointments with them instead of with abortion providers. Once at the “Crisis Pregnancy Centers,” activists then try to convince women seeking an abortion not to …

Aboriginal Food Security In Northern Canada: An Assessment Of The State Of Knowledge, Harriet Kuhnlein, Fikret Berkes, Laurie Hing Man Chan, Treena Wasonti:Io Delormier, Asbjørn Eide, Chris Furgal, Murray Humphries, Henry Huntington, Constance Macintosh, Ian Mauro, David Natcher, Barry Prentice, Chantelle Richmond, Cecilia Rocha, Kue Young

Reports & Public Policy Documents

As the world’s population increases, as global markets become more interconnected, and as the effects of climate change become clearer, the issue of food insecurity is gaining traction at local, national, and international levels. The recent global economic crisis and increased food prices have drawn attention to the urgent situation of the world’s 870 million chronically undernourished people who face the number one worldwide risk to health: hunger and malnutrition. Although about 75% of the world’s undernourished people live in low-income, rural regions of developing countries, hunger is also an issue in Canada. In 2011, 1.6 million Canadian households, or …

Pinning Motherhood: The Construction Of Mothering Identities On Pinterest, Kate Griffin

Electronic Theses and Dissertations

This research examines the new social media site, Pinterest, to uncover the processes through which mothers construct self- and public-identities. Despite being valued at over $3.8 billion dollars (Perez 2013), having an impressive user retention rate (Moore 2014), and having a highly gendered user base (Tekobbe 2013), Pinterest has been the site of limited sociological inquiry. Seventeen semi-structured qualitative interviews on mothering and Pinterest use were conducted with central Florida mothers who have a Pinterest account and at least one child between 6 months and 10 years old. Through analysis based in a grounded theory approach, three central themes emerged …

Long-Term Activity Of Biohybrid Coatings Of Atrazine-Degrading Bacteria Pseudomonas Sp. Adp, Angela K. Pannier, T. Lehrer, M. Vogel, U. Soltmann, H. Bottcher, S. Tarre, M. Green, J. Raff, K. Pollmann

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The atrazine-degrading bacterial strain Pseudomonas sp. ADP was immobilized by the sol–gel process within thin silica layers coated onto water-retaining carrier materials (expanded clay pellets and scoria). The performance of the obtained biohybrid material has been investigated concerning long-term activity under non-growth conditions. Experiments were run in phosphate buffer containing atrazine (20 mg l^-1) as the sole source of carbon and nitrogen. Even after one year of consecutive batch tests, P. ADP immobilized onto expanded clay pellets showed a high atrazine degradation activity. In the course of long-term batch experiments, the average amount of removed atrazine was about …

The Impact Of Social Constructivism On Erp Systems Security: A Critical Social Review, Kennedy Njenga

Australian Information Security Management Conference

Little is understood about the effects of social constructivism that shapes conflicting concerns regarding Enterprise Resource Planning (ERP) security and usability during implementation. This work looks at social constructivism as produced and reproduced by stakeholders in the ERP systems implementation phase. Social constructivism is characterised by the embedded trade-off for usability, espoused by end-user and security, espoused by developers. Social constructivism was conceptualised qualitatively from a selected case study. Critical Social Theory (CST) was used as the theoretical lens. Stakeholders concerned with ERP security aspects in the implementation phase were interviewed and data transcribed and interpreted. Hermeneutical interpretation was applied …

Winged Seed Songs: 32 Poems In Musical Forms & Musical Moods, Glen Phillips

ECU Books

Winged Seed Songs is a special selection of my poetry written over the last forty years or so. These poems were inspired in the main by listening to some of the world’s greatest musical works often performed in our remarkable Perth Concert Hall. I have always felt somewhat chastened by the poet’s achievements compared to those of the composer. The immediacy and universality of music’s appeal and its power to instantly induce very physical responses must make the poet envy this art form. I continue to crave the power to induce audience or reader responses as immediate and strong as …

Dance In The Museum, Claire Bishop

Publications and Research

This paper argues that the art world’s current fascination for dance follows on from a previous high point of interaction in the late 1960s and 1970s, and before that, a moment in the late 1930s and early 1940s. It traces these first, second and third waves of dance in the museum at three institutions: the Tate in London, and the Museum of Modern Art and the Whitney Museum of American Art in New York. Three institutional histories are sketched, drawing out the differences between their approaches. The conclusion presents the four most pressing possibilities/problems of presenting dance in the museum: …

Montana Cannabis Industry Association v. State of Montana and the Constitutionality of Medical Marijuana

The Forgotten Law Of Lobbying, Zephyr Teachout

Faculty Scholarship

For most of American history, until the 1950s, courts treated paid lobbying as a civic wrong, not a protected First Amendment right. Lobbying was presumptively against public policy, and lobbying contracts were not enforced. Paid lobbying threatened the integrity of individuals, legislators, lobbyists, and the integrity of society as a whole. Some states had laws criminalizing lobbying; Georgia had an anti-lobbying provision in its Constitution. Inasmuch as there was a personal right to either petition the government, or share views with officers of the government, this right was not something one could sell -- it was not, in the term …

Technology Use In Agriculture, Rebecca J. Vogt, Charlotte Narjes, Anne Byers, Connie Hancock

Cornhusker Economics

In September 2013, the Nebraska Broadband Initiative partnered with the Strategic Networks Group (SNG) to conduct an email survey of Nebraska businesses on their use of broadband technologies. Responses from over 800 Nebraska businesses show that broadband is being widely used and is benefitting businesses across the state. The complete report can be found online at http://broadband.nebraska.gov/. Seventy of those businesses self-reported being in the agriculture/forestry/fishing industry. This paper will take a closer look at the responses from this industry sector.

Retail Prices And Beef Demand, Kathleen Brooks, Matthew C. Stockton

Cornhusker Economics

Retail beef prices have continued to rise over the last several years (Figure 1, next page). They hit a record high in February 2014, with choice-beef prices selling for an average of $5.57 per pound, 7.6 percent more than a year ago. Average all-fresh beef sold for $5.28 per pound, more than 7.5 percent over the previous year. Compared to February 2010, choice beef prices have risen by 33.2 percent and all-fresh beef by 34.7 percent. Beef prices have nearly doubled since the year 2000. “Why are we seeing record high prices?” and “How have these prices been impacted by …

Does Environmental Regulation Hinder Hog Production Expansion? The Answer Is More Complicated Than The Question, Azzeddine Azzam, Karina A. Schoengold, Gibson Nene

Cornhusker Economics

Federal regulation governing management and dis-posal of the millions of tons of hog manure pro-duced every year is derived from the Clean Water Act (CWA). Enacted in 1972, the CWA amended the 1948 Federal Water Pollution Control Act to shift regulatory oversight from states to the federal government by requiring the former to adopt a federally-mandated National Pollutant Discharge Elimination System permit. Administered by the Environmental Protection Agency (EPA), the program empowers the agency to issue permits to facilities applying for permission to discharge and to do so within the agency's Effluent Limitations Guidelines and Standards. Discharge permits may also …

Liberalizing The Philippine Mining Industry: A Cge Approach Into Analyzing Its Sectoral Impacts On The Economy, Jesus Carlos Exequiel D. Castillo, Krista Danielle S. Yu

DLSU Business & Economics Review

The mining industry in the Philippines was once a promising venture that could contribute to the growth of output in the economy. Numerous legislations in support of mining in the Philippines that were passed through the years have proven ineffective in spurring development in the industry. Despite the spotted history of mining in the Philippines, the rising prices of precious metals in the world would seem that mining as a venue for output is as lustrous as ever. Due to the economic downturn in the mid 2000s, the markets turned their attention back to heavy investments in metals, causing most …

Household Food Insecurity And Obesity Risk In An Urban Slum In Brazil, Krysta Peterson

Public Health Theses

Background: The prevalence of obesity is growing among the poor. Household food insecurity (HFI) may partly explain this trend as individuals experiencing it may cope by consuming low-cost high calorie meals with little nutritive value. This study aimed to estimate the prevalence of HFI, identify its risk factors, and assess the relationship with obesity among adults in an urban slum community in Salvador, Brazil.

Design: This cross-sectional study interviewed participants at home to assess socioeconomic status, demographics, HFI (measured by the Brazilian Food Insecurity Scale (EBIA)), and health. Anthropometric measurements (height, weight, waist circumference) of each respondent were taken to …

Soil-Transmitted Nematode Infections Among School-Age Children In Rakai District, Uganda, Jensen Dalton Reckhow

Public Health Theses

One billion people are currently infected with at least one soil-transmitted nematode (STN), and over 161,600 school-aged children in sub-Saharan Africa live in areas where the prevalence exceeds 20%. STN infections cause malnutrition and cognitive deficits that limit productivity and may contribute to endemic poverty. Despite this significant and recognized disease burden, research on these diseases remains piecemeal; the majority of scientific understanding of these conditions is derived from a handful of small studies. Data regarding prevalence, intensity, and effectiveness of treatment of STN infections in Rakai District, Uganda is particularly limited, and the Ministry of Health has discontinued surveillance …

Genome-Wide Association Study Identifies Novel Ethnic-Specific Associations With Body Mass Index, Yasmmyn D. Salinas

Public Health Theses

Background. Obesity affects over one-third of the US population, and is a risk factor for various chronic conditions, including type 2 diabetes, heart disease, and stroke. The disease results from a combination of behavioral and environmental risk factors and genetic predisposition. To date, over 50 genetic polymorphisms have been associated with increased body mass index (BMI), but these associations explain only a small percentage of the heritable risk of obesity. Moreover, the majority of these associations have been identified in populations of European ancestry. We sought to identify novel associations with BMI and to evaluate their generalizability across ethnic groups, …
