Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub- Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue is whether SSA can meet this vast increase in cereal demand without greater reliance on cereal imports or major expansion of agricultural area and associated biodiversity loss and greenhouse gas emissions. Recent studies indicate that the global increase …

Crop, Tillage, And Landscape Effects On Near-Surface Soil Quality Indices In Indiana, W. Ashley Hammac, Diane E. Stott, Douglas Karlen, Cynthia A. Cambardella

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

Soil quality is a critical link between land management and water quality. We aimed to assess soil quality within the Cedar Creek Watershed, a pothole- dominated subwatershed within the St. Joseph River watershed that drains into the Western Lake Erie Basin in northeastern Indiana. The Soil Management Assessment Framework (SMAF) with 10 soil quality indicators was used to assess inherent and dynamic soil and environmental characteristics across crop rotations, tillage practices, and landscape positions. Surface physical, chemical, and nutrient component indices were high, averaging 90, 93, and 98% of the optimum, respectively. Surface biology had the lowest component score, averaging …


Heroism Research: A Review Of Theories, Methods, Challenges, And Trends, Zeno E. Franco, Scott T. Allison, Elaine L. Kinsella, Ari Kohen, Matt Langdon, Philip G. Zimbardo Dec 2016

Heroism Research: A Review Of Theories, Methods, Challenges, And Trends, Zeno E. Franco, Scott T. Allison, Elaine L. Kinsella, Ari Kohen, Matt Langdon, Philip G. Zimbardo

Department of Political Science: Faculty Publications

Heroism as an expression of self-actualization and a pinnacle social state is of fundamental interest to humanistic psychology and the field more broadly. This review places the growing discussion on heroic action in a humanistic perspective, as heroism aligns with ethical self-actualization in its highest form, personal meaning making, and social good, and can also involve profound existential costs. This review is organized in four major sections: First, the historical and philosophical underpinnings of heroism are examined, moving from ancient Greco-Roman perspectives, to more modern interpretations of Continental philosophy, and to Freud and Le Bon. Second, the article summarizes in …


Seven Characteristics Of A Good Decision, Jay Parsons Dec 2016

Seven Characteristics Of A Good Decision, Jay Parsons

Cornhusker Economics

People make thousands of decisions every day. These decisions shape lives and determine futures, some of them in very significant ways. However, some argue that the ability to make good quality decisions is contrary to human nature (Spetzler, et al.). Stress, time constraints, and uncertainty can amplify this situation and lead to mistakes that are difficult to overcome.

In a recent survey by the Department of Agricultural Economics at the University of Nebraska and the Nebraska Department of Agriculture, it was revealed that 54% of Nebraska agricultural producers are currently experiencing a great amount of financial stress. In stressful times, …

The aim of this study was to evaluate the performance of a powered ankle foot orthosis compared with unpowered orthoses in a stroke patient.

[Subjects and Methods] A single stroke subject participated in this study. The subject was fitted with three types of ankle foot orthosis (powered, posterior leg spring, and carbon ankle foot orthoses). He was asked to walk with and without the three types …


Solar, Why Not?, Emily Hergenrader Dec 2016

Solar, Why Not?, Emily Hergenrader

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Imagine yourself standing outside for an hour wearing a black shirt on a 90-degree day. Now touch your shirt. Notice how warm it is? This warming is due to the sun’s energy. According to Daniel Nocera, a member of the Division of Chemistry at the Massachusetts Institute of Technology, that same heat from one hour of sun exposure is more energy than all of the energy consumed by humans in an entire year.

Energy is one of the hottest topics debated in our world today. Human existence on Earth depends on energy usage and the availability of its consumption. Due …


Independent Energy, Ian Hall Dec 2016

Independent Energy, Ian Hall

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the world of energy, an elite selection of the world’s most influential leaders dictates the development of the world. The correlation between petroleum production and global influence is hard to ignore. The world needs energy to move and those with the energy control the movement. Saudi Arabia, Russia, and the US combine to contribute over a third of world oil production. OPEC countries however, dominate the vast energy markets around the world. Well inundated with regional conflict and hostile relations, OPEC countries remain volatile and on top of global energy production.

The energy industry has become extremely productive, fueling …


A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham Dec 2016

A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lets say you knew someone who would buy a whole pizza when they were a little bit hungry, left their sink running when they weren’t using it, maxed out their A/C in their house when they were on vacation, and always kept their stove on just in case they wanted to cook something.

You would probably see this as horribly wasteful, and a terrible drain of money. But every time we pay our power bill, our prices assume we share these wasteful habits. The rate that we pay per kilowatt hour assumes customers are eating the whole pizza, even though …


Trump Is Right, Except For A “Small” Detail, Lucas Palamim Dec 2016

Trump Is Right, Except For A “Small” Detail, Lucas Palamim

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

It is known that the elected President of the United States, Donald Trump, does not believe that human activities are causing climate change. Also, it is known that he wants to “Make America great again” by supporting the industries in the country and by investing in fossil fuel and coal energy.

Trump is a supporter of the pipelines being constructed and is against the monitoring role of the Environmental Protection Agency. The Clean Power Plan, considered President Obama’s top climate achievement, is not supported by Trump and other Republicans. It is seen as a heavy-handed rule that increases energy prices …


Fracking Chill, Nick Nardone Dec 2016

Fracking Chill, Nick Nardone

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Hydraulic Fracturing or commonly known as fracking has caused a big boom in the oil and gas industry making it easier for us to extract oil and gas from the ground, but has serious side effects that as they cause harm to us and our environment. We should slow or stop fracking at once if we want a clean and healthy environment to live in.

Fracking has become widely popular in the last decade and has brought us benefits on the oil and gas side and with little lack of information and support it has been difficult to put restrictions …


Les To Increase Fixed Price, Nathan Blazek Dec 2016

Les To Increase Fixed Price, Nathan Blazek

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lincoln Electric System (LES) plans to increase the fixed amount customers pay each month and decrease the rate it charges for each kWh used.

This shift is claimed to be revenue neutral for LES. But for customers, it means they’ll save less money by turning off lights and buying more efficient appliances.

This policy is a sly and deliberate stab at ongoing conservation efforts. The decreased kilowatt pricing will give customers the perception that it is relatively unnecessary to decrease electricity usage if they are already paying a high price to initially have it. This new policy will even further …


Is Nebraska Really “The Good Life”?, Sarah Porath Dec 2016

Is Nebraska Really “The Good Life”?, Sarah Porath

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

For anyone who has ever lived in Nebraska, you know the state is filled with people who resist change. Nebraska is “The Good Life.” Any adjustments or modifications that could disrupt the lifestyle are not welcomed. The people who are elected into office clearly reflect this type of mindset.

It is time for Nebraska to get outside of their comfort zone. We need to move from the good life to the great, healthy, and progressive life by developing a state-wide Energy Efficiency Resource Standard or Goal.

20 states have Mandated Statewide Energy Efficiency Resource Standards and 8 states have Goals …


Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood Dec 2016

Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The state of Nebraska and more specifically the Nebraska Public Power District has so far shown a surprising reluctance to incorporate clean or renewable sources of power into its portfolio. The state’s reluctance is exemplified in their support for legal challenges to the Clean Power Plan put forth by the Obama Administration. NPPD in particular has decided to stick with coal as its primary fuel source and has even discouraged the construction of natural gas facilities in the state. The power utilities in this state need to develop a modern, clean energy system to avoid being left behind.

On one …


Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal Dec 2016

Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Renewable sources will be the future of energy production for the United States. Clean sources of energy like wind and solar have been the topic of conversation for quite some time, and now they’re starting to show their ability to compete economically with fossil fuels.

Even as renewable sources of energy begin to show their gusto, they are still a part of a relatively new industry and new industries always need a little help getting off the ground. There are some forms of aid being provided for renewable sources of energy, like the production tax credit or PTCs, where the …


The Great Plains: America’S Carbon Vault, William Davidson Dec 2016

The Great Plains: America’S Carbon Vault, William Davidson

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

As a nation we are starting a race against climate change, a competitor who has had a very long head start and only plans on picking up the pace. The Clean Power Plan has laid a blueprint to lower carbon emissions from fossil fuel burning power plants nationwide, a crucial step in recovering from decades of pollution. Meeting these goals will take years and greenhouse gasses will continue to accumulate throughout the process. Efforts beyond the scope of this plan must also be made in order to prevent emissions from sources not specifically addressed, namely sources of carbon that cannot …


The Clean Power Plan And How It Will Change History, Abbie Andersen Dec 2016

The Clean Power Plan And How It Will Change History, Abbie Andersen

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In a country where 30% of the population still believes that man made climate change is a myth, president Obama has made a daring effort to help fix the damage our country has already inflicted on our planet. By creating The Clean Power Plan (CPP) we’ve taken a step in the right direction as a country. The action that we take to limit our emissions within the next 10 years will likely determine the course of the rest of our existence.

In our current situation humanity has no choice other than to act, and act quickly. We have passed the …


Why We Should Keep Worrying About The Atomic Bomb, Eric Davis Dec 2016

Why We Should Keep Worrying About The Atomic Bomb, Eric Davis

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

“… the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it highly threatening to humanity—so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight, two minutes closer to catastrophe than in 2014…Meanwhile, as they slow the pace of disarmament, the nuclear weapon states have given other strong indications that they are committed to retaining nuclear weapons for the indefinite future” - Bulletin of the Atomic Scientists (2015).

Calculating The Methan-Matics Of Our Future, Victoria Salinas Dec 2016

Calculating The Methan-Matics Of Our Future, Victoria Salinas

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the first two decades after its release, methane, a green house gas, is 84 times more potent than carbon dioxide. Historically, atmospheric concentrations of methane remained fairly stable at around 750 ppb, significantly less than today’s levels of 1,800 ppb. Unfortunately, agricultural activity accounts for about one-fifth of total global greenhouse gas emissions, while the current production of ruminants contributes nearly 80% of these emissions due to their large populations, body size and appetites, and the anaerobic microbial fermentation that occurs during digestion. Because of methane’s severe impact on the climate, methane emissions, specifically due to the production of …


Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe Dec 2016

Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

To a ten year old boy on a tedious trip across the country side, few views are more fascinating than a wind farm. Massive turbines spin slowly as if to emphasize their preposterous size and magnificence. In an era where increasing global attention is brought to climate change, renewable energy is carving its way into the minds of billions. This once free roadside attraction is now something that in the near future, we must pay and patronize, and this is where my literature begins, how willing are we to pay for renewable energy? Are you willing to pay to give …


Nebraska Monthly Economic Indicators: December 16, 2016, Eric Thompson Dec 2016

Nebraska Monthly Economic Indicators: December 16, 2016, Eric Thompson

Leading Economic Indicator Reports

Leading Economic Indicator – Nebraska (LEI-N) 1 fell by 0.32% during November of 2016. The decline in the LEI-N, which predicts economic activity six months in the future, suggests that economic growth will be modest in Nebraska during the first half of 2017. Four of six components of the LEI-N were negative during November. Airline passenger counts and manufacturing hours both declined during the month. There also was another increase in the value of the U.S. dollar during November, a negative for export-oriented businesses in Nebraska. Initial claims for unemployment insurance rose during the month. Two components of the indicator …


Teaching Place: Heritage, Home And Community, The Heart Of Education, Judy Kay Lorenzen Dec 2016

Teaching Place: Heritage, Home And Community, The Heart Of Education, Judy Kay Lorenzen

Department of English: Dissertations, Theses, and Student Research

This dissertation examines the implementation of a Place-conscious pedagogy as a means to teach heritage and sense of place. This pedagogy is framed upon the premise that trying to understand our heritage and place—ourselves—are crucial elements in our ability to live well as individuals who are connected school/community members, who help our schools/communities thrive, becoming Place-conscious citizens. I argue that in teaching in such a culturally diverse community, tensions rise as immigration has become a main focus. Our school/community has experienced many ethnic groups with vast social differences for which Place-conscious education offers practical solutions. These students have a great …


Motility And Adhesion Through Type Iv Pili In Gram-Positive Bacteria, Kurt H. Piepenbrink, Eric J. Sundberg Dec 2016

Motility And Adhesion Through Type Iv Pili In Gram-Positive Bacteria, Kurt H. Piepenbrink, Eric J. Sundberg

Food for Health: Publications

Type IV pili are hair-like bacterial surface appendages that play a role in diverse processes such as cellular adhesion, colonization, twitching motility, biofilm formation, and horizontal gene transfer. These extracellular fibers are composed exclusively or primarily of many copies of one or more pilin proteins, tightly packed in a helix so that the highly hydrophobic amino-terminus of the pilin is buried in the pilus core. Type IV pili have been characterized extensively in Gram-negative bacteria, and recent advances in high-throughput genomic sequencing have revealed that they are also widespread in Gram-positive bacteria. Here, we review the current state of knowledge …


Changes In Male Hunting Returns, Raymond B. Hames Dec 2016

Changes In Male Hunting Returns, Raymond B. Hames

Department of Anthropology: Faculty Publications

Research on changes in male hunting among hunter-gatherers addresses two important issues in early human evolution: the nature of the family and trade-offs in mating and parenting effort as well as the development of embodied capital. In the hunter-gatherer literature, there is a debate about the function of male hunting that has implications for understanding the role males play in the evolution of the pair bond. The traditional model argues that male hunting and other economic activities are forms of male provisioning or parenting effort designed to enhance a man’s fitness through his wife’s reproduction and the survivorship of their …


Who Is Trading In The Futures Markets And Why It Matters – Part 1, Fabio Mattos Dec 2016

Who Is Trading In The Futures Markets And Why It Matters – Part 1, Fabio Mattos

Cornhusker Economics

When futures markets were created in the U.S. in the mid-1800’s, market participants were mostly farmers and grain buyers looking for a tool to reduce uncertainty in their business operations. Futures contracts can be used to establish today a price for a commodity that will be delivered in the future (hedging), hence helping reduce price risk for commodity buyers and sellers. In addition, market participants can use futures prices as a reference for what the price of the commodity is expected to be in the future, thus futures markets can also be used as a price discovery tool.

Groundwater-Flow Model Of The Northern High Plains Aquifer In Colorado, Kansas, Nebraska, South Dakota, And Wyoming, Steven M. Peterson, Amanda T. Flynn, Jonathan (Jp) Traylor Dec 2016

Groundwater-Flow Model Of The Northern High Plains Aquifer In Colorado, Kansas, Nebraska, South Dakota, And Wyoming, Steven M. Peterson, Amanda T. Flynn, Jonathan (Jp) Traylor

United States Geological Survey: Water Reports and Publications

The High Plains aquifer is a nationally important water resource underlying about 175,000 square miles in parts of eight states: Colorado, Kansas, Oklahoma, Nebraska, New Mexico, South Dakota, Texas, and Wyoming. Droughts across much of the Northern High Plains from 2001 to 2007 have combined with recent (2004) legislative mandates to elevate concerns regarding future availability of groundwater and the need for additional information to support science-based water-resource management. To address these needs, the United States Geological Survey (USGS) began the High Plains Groundwater Availability Study to provide a tool for water-resource managers and other stakeholders to assess the status …


Defining Dimensions In Schizotypy: Factor Structure Replication And External Validation Of The Schizotypal Personality Questionnaire – Brief Revised Updated (Spq-Bru)., Elaina Montague Dec 2016

Defining Dimensions In Schizotypy: Factor Structure Replication And External Validation Of The Schizotypal Personality Questionnaire – Brief Revised Updated (Spq-Bru)., Elaina Montague

Department of Psychology: Dissertations, Theses, and Student Research

Background: Schizotypy is a construct that captures quantitative dimensions of the psychosis continuum from clinical to non-clinical expressions. The purpose of this study was to determine the factor structure and criterion validity of a newly revised self-report measure, the Schizotypal Personality Questionnaire–Brief Revised Updated (SPQ-BRU; Davidson, Hoffman, & Spaulding, 2016) for predicting later cognitive-perceptual experiences in college undergraduates.

Method: The data analytic sample was comprised of 2,474 undergraduate students (female = 71.9%) attending a university in the Midwest. First, we aimed to identify a model of best fit by comparing latent measurement models of schizotypy using confirmatory factor analysis (CFA). …
