Trader Joe's Case Study, Madisson Magee

Honors Program: Senior Projects (Public)

My senior project is focused around analyzing Trader Joe’s business model and writing a case study focusing on the management strategies of the company. I wanted to know what made them so successful and recognizable as brand in the grocery store industry. My case study is based off of a Harvard Business School published case. Not only did I want to understand their success, but also what factors impact them and what issues they face in maintaining a successful business model. To do this, I analyzed many aspects of their company, where they stand against competitors and internal and external …

Determinants Of Discretionary Agricultural Policy Adoption: The Case Of The Livestock Friendly County Program In Nebraska, Cicely Batie

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

This study analyzes the voluntary approach to agriculture promotion programs through the lens of the Nebraska Livestock Friendly County (LFC) Program. In 2003, the Nebraska Department of Agriculture (NDA) launched the LFC program to bolster the livestock sector in participating counties. The program is unique because of its voluntary nature and targeted agricultural promotion efforts. The NDA designates counties as “Livestock Friendly,” and assists them in streamlining approval processes for livestock feeding operations. This thesis examines why a program like LFC is necessary, the patterns of its adoption across Nebraska, and finally, its impact on the livestock sector of participating …

Changes In Whole Blood Parameters In Beef Heifers May Contribute To Delayed Pubertal Attainment, Jessica A. Keane

Department of Animal Science: Dissertations, Theses, and Student Research

Pubertal development in beef heifers is a transient period that has many contributing factors. Previously in our lab, progesterone (P4) concentrations collected from heifers at weaning (Oct) to breeding (May) were used to identify four distinct pubertal groups: Typical, Early, Start-Stop, and Non-Cycling. There is limited research on heifers and the impacts of whole blood cell populations, particularly WBCs, during pubertal development; however, girls with differing puberty onset displayed altered concentrations of hematocrit, white blood cells (WBC), and hemoglobin concentrations. Thus, our hypothesis was that heifer pubertal groups with delayed or precocious puberty may have increased white blood cells or …

The Importance Of Nutrition And Preventing Malnutrition In Older Adults: A Literature Review And Informational Booklet, Sophie Johnson

Honors Program: Senior Projects (Public)

Over years of studying nutrition science and gerontology, there was very little information in classes that combined these two important topics. Older adults are often classified as those above the age of 65 years old. There is a growing number of older adults in the United States, which increases the need for information on how nutrition and aging are interlaced. As humans age, multiple factors can impact nutrition. Nutrition involves consuming the proper amount of nutrients to maintain body function. There are physiological, physical, socioeconomic and medication factors that can all influence nutrition status. It is important to be aware …

Unprecedented Migratory Bird Die-Off: A Citizen-Based Analysis On The Spatiotemporal Patterns Of Mass Mortality Events In The Western United States, Di Yang, Anni Yang, Jue Yang, Rongting Xu, Han Qiu

United States Department of Agriculture Wildlife Services: Staff Publications

Extensive, severe wildfires, and wildfire-induced smoke occurred across the western and central United States since August 2020. Wildfires resulting in the loss of habitats and emission of particulate matter and volatile organic compounds pose serious threatens to wildlife and human populations, especially for avian species, the respiratory system of which are sensitive to air pollutions. At the same time, the extreme weather (e.g., snowstorms) in late summer may also impact bird migration by cutting off their food supply and promoting their migration before they were physiologically ready. In this study, we investigated the environmental drivers of massive bird die-offs by …

Transcending Adversity: Trauma-Informed Educational Development, Mays Imad

To Improve the Academy: A Journal of Educational Development

The purpose of this article is to reflect on the pertinence and utility of using a trauma-informed lens in educational development. A trauma-informed approach is a framework grounded in an understanding of and responsiveness to the impact of trauma. After I describe the primary source of traumatic stress many faculty members are experiencing, I offer trauma-informed suggestions for how educational developers can help mitigate the effects of that stress. Importantly, in order to do this work of supporting faculty effectively and sustainably, it is critical that educational developers continue to attend to their own well-being. The overarching theme of this …

The Use Of Egyptian Blue In Funerary Paintings From Roman Egypt, Margaret Sather

School of Art, Art History, and Design: Theses and Student Creative Work

This paper explores the use of the synthesized pigment Egyptian blue in the encaustic and tempera funerary portraits of Graeco-Roman ruled Egypt in the 1st-3rd centuries CE. Recent developments in non-destructive imaging analysis technology have aided research institutions and museums in detecting the presence of this pigment. New questions have arisen based on these findings of Egyptian blue in the depiction of flesh and hair of these subjects, particularly because blue is so rarely used as a standalone pigment in works of this category. These analyses have challenged assumptions that Egyptian blue was a rare and valuable pigment during the …

Comparing A Mixed Model Approach To Traditional Stability Estimators For Mapping Genotype By Environment Interactions And Yield Stability In Soybean [Glycine Max (L.) Merr.], Mary M. Happ, George L. Graef, Haichuan Wang, Reka Howard, Luis Posadas, David L. Hyten

Department of Agronomy and Horticulture: Faculty Publications

Identifying genetic loci associated with yield stability has helped plant breeders and geneticists begin to understand the role and influence of genotype by environment (GxE) interactions in soybean [Glycine max (L.) Merr.] productivity, as well as other crops. Quantifying a genotype’s range of performance across testing locations has been developed over decades with dozens of methodologies available. This includes directly modeling GxE interactions as part of an overall model for yield, as well as methods which generate overall yield “stability” values from multi-environment trial data. Correspondence between these methods as it pertains to the outcomes of genome wide association studies …

Monitoring And Trends Of Antimicrobial Use In Livestock Production, Elliott James Dennis

Cornhusker Economics

There has been growing consumer and human medical profession concern about the use of “Shared Use/Medically Important” antimicrobials in food-animal production. The concern partially stems from the concern that livestock and poultry fed antimicrobials can develop resistant bacteria which can then be passed on to humans primarily via consumed meat and poultry products. To curtail this real or hypothetical consumer concern, major restaurants, food service companies, food processors, and supermarkets have pledged to reduce or eliminate meat and poultry that were raised with a non-negative quantity of antimicrobials. For example, Wendy’s© pledged that 50% of procured beef would come from …

Association Between Clinical Respiratory Signs, Lung Lesions Detected By Thoracic Ultrasonography And Growth Performance In Pre‐Weaned Dairy Calves, Inmaculada Cuevas-Gomez, Mark Mcgee, Jose Maria Sanchez, Edward O'Riordan, Nicky Byrne, Tara Mcdaneld, Bernadette Earley

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Background: Bovine respiratory disease (BRD) is the main cause of mortality among 1-to-5 month old calves in Ireland, accounting for approximately one-third of deaths. Despite widespread use of clinical respiratory signs for diagnosing BRD, lung lesions are detected, using thoracic ultrasonography (TUS) or following post-mortem, in calves showing no clinical signs. This highlights the limitation of clinical respiratory signs as a method of detecting sub-clinical BRD. Using 53 purchased artificially-reared male dairy calves, the objectives of this study were to: (i) characterise the BRD incidence detected by clinical respiratory signs and/or TUS, (ii) investigate the association between clinical respiratory signs …

Seasonal Variation In The Effects Of Urban Environmental Factors On Land Surface Temperature In A Winter City, Wen Wu, Lidong Li, Chunlin Li

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

Environmental factors such as urban landscape patterns, local climate, topography, and socioeconomic conditions have significant impacts on land surface temperature (LST), especially through the urban heat island effect. At present, in-depth studies on the mechanisms determining LST in different seasons in winter cities are lacking. In this study, we used structural equation modeling for 12 environmental factors to characterize how these factors affect the temporal and spatial heterogeneity of the LST in the winter city of Shenyang, China. We found that the most critical factors affecting LST varied with season. Specifically, the distances from the nearest water body and nearest …

Training Tests, Megan Paul

Umbrella Summaries

What are training tests?

For this purpose, training tests include any form of knowledge assessment intended to gauge learning from training. Tests can be of varying lengths, formats (e.g., true/false, multiple choice, short answer), or labels (e.g., quiz, learning checks). The important feature is that they require learners to practice retrieving training-related information from memory. Thus, the focus here is on knowledge and understanding, versus skill acquisition.

Why are training tests valuable?

Training tests are valuable because the act of taking a test improves subsequent learning outcomes. More specifically, people who take a test perform better on later assessments of …

Dataset Search In Biodiversity Research: Do Metadata In Data Repositories Reflect Scholarly Information Needs?, Felicitas Löffler, Valentin Wesp, Brigitta König-Ries, Friederike Klan

Copyright, Fair Use, Scholarly Communication, etc.

Abstract

The increasing amount of publicly available research data provides the opportunity to link and integrate data in order to create and prove novel hypotheses, to repeat experiments or to compare recent data to data collected at a different time or place. However, recent studies have shown that retrieving relevant data for data reuse is a time-consuming task in daily research practice. In this study, we explore what hampers dataset retrieval in biodiversity research, a field that produces a large amount of heterogeneous data. In particular, we focus on scholarly search interests and metadata, the primary source of data in …

Full Spectrum Space Deterrence: From Laws To Technology, Joshua Carlson

Honors Program: Senior Projects (Public)

Conflict in space is becoming an ever-real possibility, with the potential of rendering the space completely useless for future generations. Current talks are centered around limiting or preventing any weapons deployed to space, but this is not the most effective way of dealing with the issue. The focus should shift to agreeing on how nations should act responsibly in space together instead of preventing nations from acting at all. The best way of accomplishing this goal is by improving satellite design, creating agreed upon and understood rules of engagement, fostering widespread cooperation between nations, and choosing not to be the …

Exploring Viirs Continuity With Modis In An Expedited Capability For Monitoring Drought-Related Vegetation Conditions, Trenton D. Benedict, Jesslyn F. Brown, Stephen P. Boyte, Daniel M. Howard, Brian A. Fuchs, Brian D. Wardlow, Tsegaye Tadesse, Kirk A. Evenson

National Drought Mitigation Center: Faculty Publications

Vegetation has been effectively monitored using remote sensing time-series vegetation index (VI) data for several decades. Drought monitoring has been a common application with algorithms tuned to capturing anomalous temporal and spatial vegetation patterns. Drought stress models, such as the Vegetation Drought Response Index (VegDRI), often use VIs like the Normalized Difference Vegetation Index (NDVI). The EROS expedited Moderate Resolution Imaging Spectrora-diometer (eMODIS)-based, 7-day NDVI composites are integral to the VegDRI. As MODIS satellite platforms (Terra and Aqua) approach mission end, the Visible Infrared Imaging Radiometer Suite (VIIRS) presents an alternate NDVI source, with daily collection, similar band passes, and …

Discussion Of “Is Group Testing Ready For Prime-Time In Disease Identification?” By Haber, Malinovsky, And Albert, Statistics In Medicine, 2021, Brad J. Biggerstaff

United States Public Health Resources

I congratulate the authors on an interesting, instructive, and timely paper. Certainly, including the testing for SARS-CoV-2 example in a paper on a topic—group testing—of wide interest during the current COVID-19 pandemic emphasizes the relevance of the topic in public health and diagnostic medicine generally. But the thoughtful inclusion of the remaining examples—HIV, HPV, and cancer biomarker detection—illustrates that the issues considered are important even in less urgent times. In this note of discussion I will comment on two particular aspects in the paper that I found particularly informative, and then I will comment on two other, related areas that …

Mental Model-Based Repeated Multifaceted (Mrm) Intervention Design: A Conceptual Framework For Improving Preventive Health Behaviors And Outcomes, Mazbahul G. Ahamad, Fahian Tanin

Department of Agronomy and Horticulture: Faculty Publications

Objective: Field interventions employed to improve preventive health behaviors and outcomes generally use well established approaches; however, recent studies have reported that health education and promotional interventions have little to no impact on health behaviors, especially in low- and middle-income countries. We aimed to develop a conceptual framework to improve intervention designs that would internalize these concerns and limitations.

Results: We identified three major experimental design- and implementation-related concerns associated with mental models, including the balance between the treatment and control groups, the treatment group’s willingness to adopt suggested behaviors, and the type, length, frequency, intensity, and sequence of treatments. …

Honors Program: Senior Projects (Public)

In recent times the prevalence of the Spanish language in the United States has been on a steady incline, and the language barrier created between patients and providers is only growing. Studies display a direct relationship between communication barriers formed by insufficient interpretation methods and negative patient outcomes due to a lack of understanding. This study will evaluate of the effects of Spanish-English interpretation in the United States health system as well as review the significance of direct patient-provider communication and how to improve these methods. Research methods will involve the use of other accredited academic literature and studies, as …

Exploring Factors In Choosing Stem Majors And Careers: Improving Science Education Through The Lens Of Self-Determination Theory, Lauren Mott

Honors Program: Senior Projects (Public)

Several barriers currently exist for students who could be successful in science/STEM careers but have not had the support they needed throughout their science/STEM education. This study of the literature applies Self-Determination Theory (SDT) to existing research to identify steps educators can take to remove these unnecessary barriers for their students. SDT defines competence, relatedness, and autonomy as three innate psychological needs that must be met for well-being. An exploratory review of the literature was conducted, and findings were organized using SDT. The results showed that competence, relatedness, and autonomy were all key factors in students’ self-determination of science/STEM careers. …
