Community Development In The Time Of Covid-19, Daniela Mattos

Cornhusker Economics

The global pandemic has driven the whole country into an unprecedented crisis. As the months passed and the death toll climbed, the pandemic did some-thing else: it unveiled deep inequities within the country. Those getting sick and dying were disproportionately low-income racial and ethnographic minorities, most of them essential workers. According to the lat-est data from the Center for Disease Control and Prevention, the virus has overly affected Black people and Latinos (https://www.cdc.gov/coronavirus/2019-ncov/covid-data/covidview/index.html). Communities of color are also over represented among essential workers who are generally unable to work from home and more likely to come into contact with the …

The Role Of Myopic Loss Aversion In Pre-Harvest Grain Marketing, Iyore Eronmwon

Department of Agricultural Economics: Dissertations, Theses, and Student Research

In this study, we investigate the role of myopic loss aversion (MLA) risk preferences on pre-harvest grain marketing decisions using a laboratory experiment. Prospect theory parameters were estimated to measure MLA. We estimated a power function for utility and obtained power estimates indicating linear utility for gains and concave utility for losses. We obtained a loss aversion parameter estimate that suggests the presence of loss aversion. We found evidence of probability weighting for both gains and losses. We classified individuals into three categories based on their MLA status. They are no NMLA, MLA, and high loss aversion (HLA). We observed …

Assumptions (Mistakes) That Parents Make With Estate Plans, Allan Vyhnalek

Cornhusker Economics

The main goal of many parents when writing their estate plan is for their children to continue to be a family. With this goal in mind, parents make many assumptions to “keep the peace” when planning their estate. If the family has a key fight then family activities, like holiday gatherings, no longer happen. Let’s look at these assumptions and make some observations about each. The overall goal is to think through our actions with the intent that the family stays together.

Without an estate plan, the assets are divided ac-cording to the laws of the state of Nebraska. That …

The Concept Of Natureculture Document: A Conceptual Exploration Of Seeds, Embodied Information, And Unconventional Records, Marc Kosciejew

Journal of Contemporary Archival Studies

Seedbanks, or so-called archival arks of the apocalypse, are addressing accelerating anthropocentric alterations to the environment by collecting, storing, and preserving seeds. These are specialized archival repositories that approach, frame, and use seeds as documents for agricultural and scientific research, classification and preservation work, and various other archival and administrative purposes. Seedbanks indeed are archives of unconventional records.

This article introduces the concept of natureculture document as a framing device in which to help analyze the documentary status of objects that are not necessarily or usually considered as documents or having documentary characteristics. This concept, coupled with its interdisciplinary theoretical …

Uncertainties Abound In Nebraska Livestock Market Forecasts, Elliott James Dennis

Extension Farm and Ranch Management News

About one of the only things certain about forecasts this year has been the great deal of uncertainty. Numerous “novel” situations have confronted the industry making it difficult to estimate price magnitudes rather than just price direction. Clustered plant closures, government quarantine restrictions, and increasing at home phone consumption are just a few of the major issues the beef industry has had to tackle in the last six to eight months. Some things have returned to “normal” such as packing plant capacity and food service demand. Others are still in ongoing recovery.

Who knows what “normal” or “standard operating procedure” …

Winning In Weight-Loss: The Interaction Of Conscientiousness And Perceived Autonomy, Jason M. Curtis, Marc Lochbaum

Journal for Sports Neuroscience

ABSTRACT

Background

Understanding determinants for weight-loss is a national priority. Obesity is an epidemic with serious health consequences. Most of today’s obesity and overweight problems are being attributed to poor diets and not enough physical activity. These problems show no signs of slowing down with the behaviors of most Americans. The phenomenon of “The Biggest Loser” (different variants of weight-loss programs that consist of group exercise participation and nutrition therapy to elicit weight-loss, and hopefully behavior change) has spawned many variants in commercial health clubs. This prospectus study examined the direct and interactive or moderated effects of known determinants of …

Comparing Profitability And Management Factors Across Operation Type: Independent Vs. Contract Growing, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replacing commercial fertilizer expense as the primary reasons for adding a hog barn.

Homicide And Drug Trafficking In Impoverished Communities In Brazil, Elenice De Souza Oliveira, Braulio Figueiredo Alves Da Silva, Flavio Luiz Sapori, Gabriela Gomes Cardoso

Department of Justice Studies Faculty Scholarship and Creative Works

Many studies demonstrate that homicides are heavily concentrated in impoverished neighborhoods, but not all socially disadvantaged neighborhoods are hotbeds of violence. Conducted in Belo Horizonte, Brazil, this study hypothesizes that the association between high rates of homicide and impoverished areas is influenced by the emergence of a specific type of street drug-dealing common to favelas (slums). The study applies econometric techniques to police data on homicides and drug arrests from 2008 to 2011, as well as 2010 Census data, to test its hypothesis. The findings provide insight into the development of crime prevention policies in areas of high social vulnerability.

Personalized Medicine: The Use Of Biomarkers And Molecularly Targeted Therapies For Patient Care And Cancer Intervention, Wafa Asad, Emily Schmitt Lavin

Mako: NSU Undergraduate Student Journal

Personalized medicine and targeted therapy have been emerging fields of study for the remediation and inhibition of cancer. Personalized medicine in the treatment of cancer involves using genetic, immune, and proteomic profiling to provide therapeutic options as well as prognostic background for every patient and their tumor’s genetic mutations. Targeted therapies allow researchers and medical personnel alike to determine the appropriate treatment for a patient based on the molecular basis and mechanistic actions of a cancerous tumor. The overall significance of this study was to express how these treatments use biomarkers to pinpoint the location, and severity of the cancer, …

Financial Health Of Grain Operations After Adding A Hog Barn, Elliott James Dennis

Extension Farm and Ranch Management News

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replace commercial fertilizer expense as the primary reasons for adding a hog barn.

While there is industry demand to increase hog contract growing, these agreements can possess significant benefits and risks to producers. This is the second of a four part series which will discuss some financial and legal implications of adding a hog barn to an …

Determinants Of Gluten-Free Diet Adoption Among Individuals Without Celiac Disease Or Non-Celiac Gluten Sensitivity, Kristina Arslain, Christopher Gustafson, Pratiksha Baishya, Devin Rose

Department of Agricultural Economics: Faculty Publications

Objectives: Gluten free (GF) foods are typically less nutritious and more expensive than their gluten-containing variants, yet people without a diagnosed gluten sensitivity continue to adopt this diet. There is a lack of research about what factors drive people without Celiac disease or non-Celiac gluten sensitivity to follow the GF diet. Methods: A nationally representative sample of 2982 US residents without a diagnosed gluten sensitivity were surveyed about their attitudes, perceptions, and experiences with the GF diet. Logistic regression was used to compare respondents who were currently avoiding or had avoided gluten previously (GF consumer) to respondents who had never …

Multi-Peril Crop Insurance Basics, Matthew Stockton, Duran Rudnick, Chuck Burr

Cornhusker Economics

The Federal crop insurance corporation (FCIC) https://www.rma.usda.gov/Federal-Crop-Insurance-Corporation and https://www.everycrsreport.com/reports/R45193.html offers three types and eight levels of taxpayer subsidized multi-peril crop insurance (MPCI) policies, sold for four different unit types. The unit types are designed to define the nature of the farm area being insured. There are four types of insurable units, optional, basic, enterprise and whole farm. Each of these units has differences in costs per acre and is likely to create variations in indemnities. For example, a highly localized severe hail storm on a single field covered using basic units would likely have an indemnity, versus not likely to …

Evidence For Height And Immune Function Trade-Offs Among Preadolescents In A High Pathogen Population, Angela R. Garcia, Aaron Blackwell, Benjamin C. Trumble, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven

ESI Publications

Background

In an energy-limited environment, caloric investments in one characteristic should trade-off with investments in other characteristics. In high pathogen ecologies, biasing energy allocation towards immune function over growth would be predicted, given strong selective pressures against early-life mortality.

Methodology

In the present study, we use flow cytometry to examine trade-offs between adaptive immune function (T cell subsets, B cells), innate immune function (natural killer cells), adaptive to innate ratio and height-for-age z scores (HAZ) among young children (N = 344; aged 2 months–8 years) in the Bolivian Amazon, using maternal BMI and child weight-for-height z scores (WHZ) as …

Advising Physiology Students: Perceptions From The Programs, Anne R. Crecelius, Patrick L. Crosswhite

Health and Sport Science Faculty Publications

Academic advising outcomes can be linked to both student success and retention. Yet relatively little is known specifically related to advising in physiology programs. Pro- fessional organizations dedicated to academic advising in general, and more specifically advising future health professional students exist, yet, whether current physiology programs utilize these resources remains unknown, as does a number of other demographic informa- tion about advising in physiology programs. Here we present data gathered from a sample of physiology educators to inform what current advising practices of physiology students are. Forty-five re- spondents from a variety of institutions and programs provided information on …

United States National Park Service: Publications

Executive Summary

Since Agate Springs Ranch was founded by James H. Cook in 1887, exquisite examples of transitional Miocene mammalian fauna have been found along this stretch of the Niobrara River valley. Collectively these paleontological discoveries, along with the existing archeological and historical Native American collection, were the basis for establishing Agate Fossil Beds National Monument (AGFO) as a unit of the National Park System (NPS). The fossil remains from the Harrison and Anderson Ranch formations span a short, but important, time period within the Miocene Epoch. AGFO has provided science with an intimate look into North American mammalian evolution …

Health and Sport Science Faculty Publications

Undergraduate degree programs named “Physiology” have existed for over 50 yr. The number of programs and enrolled students have been growing since ~2005 (5, 9). There are many thousands of students currently enrolled in physiology pro- grams across the United States and indeed across the world. Despite the long history and current popularity of the physiol- ogy major, there is no coordinated plan articulated for the design, administration, or assessment of degree programs in physiology at the undergraduate level.

Although several professional societies have invested in under- graduate physiology education in various ways, none has under- taken the task of …

A Glance At The Mirror: Ensemble Perception Of Symmetry, Gene Jerskey

Dissertations, Theses, and Capstone Projects

A growing body of research has demonstrated the ability of subjects to extract representative statistics from visual ensembles, images of similar but distinct groups of objects, without conscious effort or attention focused on individual members of the ensemble. When presented with ensembles, subjects have been able to accurately report the mean, range, and even distribution of various features in the ensemble. Research into ensemble perception, as it has become known, has divided mainly into studies of either low-level features, such as orientation, motion, and color, which are processed in early visual areas, at least for individual objects, or high-level features, …

Analysis Of Newspaper Coverage Of Psilocybin From January 1, 1989 To December 31, 2019, Dax Oliver

Dissertations, Theses, and Capstone Projects

Psilocybin is a chemical compound that has received a lot of attention from medical researchers in recent years. However, this research is not merely a medical issue but a social and political one as well. In the 1960s, psilocybin and other psychedelic compounds were widely ingested outside of clinical settings. This alarmed some of the American public, resulting in severe legal restrictions on psilocybin use and research.

Today, many psilocybin advocates hope that it will avoid the negative public sentiment of the 1960s. To help gauge public sentiment about other psychoactive compounds, some studies have examined newspaper coverage, but there …

Neurodevelopmental Mechanisms Of Adverse Trauma Outcomes In Emerging Adulthood, Olena Kleshchova

Dissertations, Theses, and Capstone Projects

Background: Exposure to traumatic stress and adversity during the formative years of development can have adverse effects on mental health, neuroendocrine stress system function, and the brain, that persist into adulthood. One candidate mechanism that might confer vulnerability to enduring adverse outcomes of early life trauma is disruption of normal brain maturation. As the brain matures, functional interactions among brain regions change until the functional brain architecture (i.e., the functional connectome) reaches a mature state in adulthood. Given that different neural circuits have distinct developmental trajectories and sensitive periods, traumatic stress at a given point in development might have …

Sex/Gender Differences In Serial Position Profiles In Patients With Mild Cognitive Impairment And Healthy Controls, Emnet Z. Gammada

Dissertations, Theses, and Capstone Projects

Introduction: Alzheimer’s disease disproportionately affects more women, but paradoxically, men have a higher incidence of Mild Cognitive Impairment (MCI). Researchers have suggested that women’s verbal memory advantage across the lifespan reflects better premorbid skills, which then require more neurodegeneration to manifest early clinical impairment. To date, measurement of sex differences in verbal memory have used total list scores. We proposed that a granular examination of serial position effects (SPE) in list-learning can refine the source of sex/gender differences.

Methods: A cross-sectional analysis of participants with Mild Cognitive Impairment (MCI) and Healthy Controls (HC) was examined from the Alzheimer’s Disease Neuroimaging …

Integrating Affect Perception Tasks From The New York Emotion Battery Into A Comprehensive Measure Of Neuropsychological Change Across The Lifespan, Melinda A. Cornwell

Dissertations, Theses, and Capstone Projects

Background: The ability to perceive others’ emotions is a vital skill for social competency, impacting the success of personal and professional relationships (Brinton & Fujiki, 2011; Cassidy et al., 1992; Côté & Miners, 2006). According to Socioemotional Selectivity Theory (SST; Carstensen, 1991), human motivation develops to become more discerning in choosing milieus that yield the most gratifying return on the investment of personal resources (e.g., time, attention, and effort), perhaps explaining why some research findings indicate that older adults may demonstrate an affect perception (AP) bias described as a positivity effect (Reed et al., 2014). Moreover, AP predicts cognitive and …

The Temporal Dynamics Of Ensemble Perception, Michael L. Epstein

Dissertations, Theses, and Capstone Projects

The striking disparity between the subjective richness of experience and the considerable limitations of perceptual processing has emerged as an essential, enduring question in both vision science and philosophy of mind. A potential solution to this issue is ensemble perception: the ability for the visual system to compute the statistical summaries of object groups, effectively compressing an otherwise overwhelming amount of information. Previous work has supported that ensemble statistics can be perceived quickly and accurately for a wide range of object features. This has motivated models of ensemble perception as an early process in vision, providing an initial sense of …

Structural And Functional Brain Markers Of Trauma-Related Symptoms, Glenn Blessington

Dissertations, Theses, and Capstone Projects

The neurocircuitry model of posttraumatic stress disorder suggests an association between trauma-related symptoms and abnormalities in the structure and function of limbic and prefrontal brain regions. Evidence also suggests that these structural and functional abnormalities are related. We tested the relation between whole brain white matter integrity, resting-state functional connectivity of a fronto-limbic network, and trauma-related symptoms in 22 trauma-exposed women. We hypothesized that components of whole brain white matter would correlate with components of resting connectivity within a fronto-limbic network. We used parallel independent component analysis (pICA) to test the associations between whole brain fractional anisotropy (FA) maps and …
