Cultural And Reproductive Success And The Causes Of War: A Yanomamö Perspective, Raymond B. Hames

Department of Anthropology: Faculty Publications

Inter-group competition including warfare is posited to be a key force in human evolution (Alexander, 1990; Choi & Bowles, 2007; Wrangham, 1999). Chagnon's research on the Yanomamö is seminal to understanding warfare in the types of societies characteristic of human evolutionary history. Chagnon's empirical analyses of the hypothesis that competition for status or cultural success is linked to reproduction (Irons, 1979) and warfare attracted considerable controversy. Potential causal factors include “blood revenge”, mate competition, resource shortages or inequality, and peace-making institutions (Boehm, 1984; Keeley's (1997); Meggitt, 1977; Wiessner and Pupu, 2012; Wrangham et al., 2006). Here we highlight Chagnon's contributions …

Working Trees Info: Can Innovative Land Access Strategies For Agroforestry Provide More Land Management Options?

Working Trees (USDA-NAC)

An agricultural lease is a private contract that grants someone (the farmer-tenant) a legal right to occupy and use the land of someone else (the landlord/landowner) for agricultural purposes. The long-term lease allows the farmer to secure long-term land tenure without requiring a lot of money upfront. Other long-term land access strategies include easements and licenses.

Long-term land access strategies are particularly key for farmers engaged in agroforestry ventures, as perennial woody crops inherently require extended time before becoming economically productive and can remain productive for a number of years.

What's The Problem Now?, Randall Bass

To Improve the Academy: A Journal of Educational Development

Revisiting an essay from 1999, this article explores the current conditions in higher education, and society more broadly, that help shape the roles for the scholarship of teaching and learning (SoTL) and educational development. By seeing the current “crises” of higher education not only as “problems” to be investigated but as a “wicked problem,” we might be able to elevate and complicate the role that inquiry into teaching and learning might play in institutional change and the expansion of higher education. The article argues for the necessity, even urgency, of seeing educational development as a lever for change, fully engaged …

(Cultural) Taxation Without Representation? How Educational Developer Can Broker Discourse On Black Faculty Lives In The #Blacklivesmatter Era, Richard J. Reddick, Beth E. Bukoski, Stella L. Smith

To Improve the Academy: A Journal of Educational Development

Predominantly White institutions (PWIs) in creative class cities offer contradictory experiences for Black faculty, who engage in invisible additional labor in response to racial aggressions, termed cultural taxation (CT). With an understanding that equity-minded faculty development is an essential space in which to respond to this reality, our study employed a phenomenological focus group design to investigate how Black faculty at a research-intensive PWI located in a creative class city buffeted by racial tensions navigated their service and community experiences. While finding their work meaningful, the participants shared experiences of the multifaceted nature of CT, their stress from teaching about …

To Improve the Academy: A Journal of Educational Development

This critical retrospective review describes the ideation, creation, and implementation of a faculty development fellows program at a regional comprehensive university. The authors share their perspectives as fellows regarding primary considerations for designing the program, including attention to the fellows selection process, required multilevel support, cultivation of communication and relationships, professional development of the fellows, development of unit programming, and lessons learned. Each section of the article concludes with critical questions institutions might consider when conceiving a faculty development fellows program.

A Global Perspective On Sustainable Intensification Research, Kenneth Cassman, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Despite general agreement that meeting food demand without further loss of natural ecosystems requires sustainable intensification, there is little dialogue about the research agenda needed to achieve it. To that end, we evaluate current trajectories towards sustainable intensification, review published research on the topic, identify missing links, and propose a prioritization framework to fill gaps. Although progress towards sustainable intensification is behind schedule, we are optimistic that current trends can get back on course assuming a well-prioritized and adequately funded research portfolio and appropriate policies and institutions to support it.

Investigating Microbiomes And Developing Direct-Fed Microbials To Improve Cattle Health, Alison C. Bartenslager

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

Over the last decade, global beef production has increased to meet the protein needs of the growing population. As a result, the intensification of beef cattle production systems has resulted in broad spectrum prophylactic use of antibiotics and growth promoting agents. With increased concern around antimicrobial resistance (AMR) and emergence of novel pathogenic strains of bacteria, it is critical to understand disease progression and associated changes in the microbiome to develop novel therapeutic alternatives to reduce antibiotic use and control disease. One such approach that is currently being investigated is the development of novel direct-fed microbial strains to outcompete pathogens …

Heat Stress-Induced Deficits In Growth, Metabolic Efficiency, And Cardiovascular Function Coincided With Chronic Systemic Inflammation And Hypercatecholaminemia In Ractopamine-Supplemented Feedlot Lambs: Atypical Cyclicity At Puberty In Beef Cows Is Associated With Early Deficits In Muscling, Metabolic Indicators, And Myoblast Function In Offspring But Does Not Impact Feedlot Performance, Rebecca M. Swanson

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

Our 1^st study evaluated the effects of b-adrenergic agonist (ractopamine) supplementation on growth, health, and wellbeing in heat-stressed feedlot wethers. Chronic heat stress impaired growth, metabolism, and wellbeing even when the impact of reduced feed intake was eliminated by pair-feeding. We observed systemic inflammation and hypercatecholaminemia that were likely mediators of these deficits. Moreover, ractopamine did not diminish any wellbeing indicators and improved muscle growth without worsening the effects of heat stress.

Our 2^nd study assessed the effects of pubertal cyclicity (weaning to 1^st breeding) in cows on myoblast-mediated muscle growth, metabolism, and growth efficiency of their …

Stunting And Infectious Disease In Ethiopian And Zambian Children, Alyssa Arndt

NUTR/GLST 498b: Global Research Experiences in Nutrition and Health

PURPOSE: To evaluate whether children who are malnourished/stunted are more likely to have experienced infectious disease.

METHODS: 6th and 7th students (n=546) were interviewed about health history and assessed using anthropometry.

RESULTS: Children who are short for their age also have higher rates of stunting. Malaria is the most experienced infectious disease.

CONCLUSIONS: Given that malaria was the most common infectious disease experience listed among middle school children, and that those who have experienced disease are more likely to be stunted, increased malaria prevention methods may improve the long-term health of Ethiopian and Zambian schoolchildren.

Occurrence And Persistence Of Antibiotics Administered To Cattle In A Newly Established Feedlot, Brittany Trejo

Department of Environmental Engineering: Theses and Other Student Research

The common practice of using therapeutic antibiotics in livestock farming is a worldwide phenomenon. Over the last decade, there has been a growing concern of antibiotics entering the environment via animal manure. Similar studies have focused on the occurrence and biological effects of antibiotics in land-applied animal feedlots; however, limited research has been conducted on the occurrence and persistence of antibiotics in animal feedlots. A study was conducted to investigate the occurrence and persistence of four injected antibiotics (ceftiofur enrofloxacin, florfenicol, and tulathromycin) and two continuously fed antibiotics (monensin and tylosin) in feedlot sediment, runoff, and sediment runoff. For antibiotics …

Federal Land-Use Policy And Resettlement In The Great Plains: An Experiment In Community Development During The New Deal Years, 1933–1941, Theresa Glanz

Department of Geography: Dissertations, Theses, and Student Research

In 1933, the United States federal government authorized the National Industrial Recovery Act to help the country recover from the Great Depression. Section 208, Title II of the National Industrial Recovery Act authorized the creation of subsistence homesteads to aid in the recovery of destitute rural families and the urban unemployed. Between 1933 and 1941, the United States federal government authorized the construction of 207 rural and urban resettlement communities to house impoverished farm families and unemployed urban workers. The projects were located throughout the United States, including in the territories of Hawaii, Alaska, Puerto Rico, and the U.S. Virgin …

The Impact Of Nicotine Accumulation Exposure On Lithobates Catebeianus Larvae Mortality, Luke Micek

UCARE: Research Products

Cigarette butts are the most littered item in the world and contain over 4,000 chemicals, including the organic compound nicotine (Slaughter et al. 2011). Billions of cigarette butts are littered each year which may wash into bodies of water, impacting the local wildlife. To determine how introduced chemicals impact the environment, it is important to study its effects on indicator species. Amphibians, such as Lithobates catebeianus, act as indicator species due to their extreme sensitivity to chemical changes in its environment. The purpose of this research project was to obtain data to help determine the impact nicotine accumulation has …

Mitochondria As A Potential Antifungal Target For Isocyanide Compounds, Nancy Nguyen, Virendra Tiwari, Medhanjali Dasgupta, David Berkowitz, Mark A. Wilson, Wayne R. Riekhof

UCARE: Research Products

The discovery of antibiotics and antifungals greatly impacted medicine and human health, allowing the effective treatment of infections that were previously deadly. However, due to routine and sometimes excessive usage of these compounds, the development of antimicrobial resistance has created a need for new antibiotic and antifungal compounds. Isocyanide compounds have been shown to have antibacterial, antifungal, and anti-cancer properties, but very little is known about their biochemical effects. Our research aims to understand the mechanism of action of isocyanide compounds. We have conducted a genetic screen of a Saccharomyces gene-deletion (“knockout”) collection on media containing an easily synthesized model …

The Effect Of Self-Construal And Relationship On Psychological Motivations Of Dispute Resolution, Jared Syed Noetzel, Abigail Herzfeld, Ashley Votruba

UCARE: Research Products

Culture acts as a lens that can influence many aspects of an individual’s life, such as their health perceptions, cognition, and even their preferred style of conflict resolution. We predict that an individual’s self-construal and the relationship to the conflicting party affects their psychological motivations for choosing a conflict style. Previous research suggests that the aforementioned goals can drive dispute resolution preferences. We hypothesized that participants with high interdependent self-construal would rate goals of animosity reduction and relationship restoration higher than participants low in interdependent self-constural, while participants with high independent self-construal would rate the goal of process control higher …

Assembly And Identification Of Novel Viruses In The Aquatic Invertebrate Daphnia Magna, Freddy L. Gonzalez, Reilly O. Cooper, Clayton E. Cressler

UCARE: Research Products

Microbiome studies have been critical to understanding host health and life history. Many studies primarily focus on understanding the impacts of bacteria on the host, while fewer examine the impacts of viruses on host fitness or the interaction between viruses and bacteria within a host. Here, we utilized shotgun sequencing to identify whether viruses were present in the model organism Daphnia magna. VIBRANT, a bioinformatic tool that utilizes hybrid machine learning and protein similarity to identify lytic genomes and other novel viruses, was used on sequencing data from four samples of adult and juvenile Daphnia. We found a …

Nanoparticle Treatment To Counter Reactive Oxygen Species After Traumatic Brain Injury, Brandon Mcdonald, Forrest Kievit

UCARE: Research Products

Traumatic brain injury (TBI) is defined as damage to the brain, resulting from an external mechanical force, such as an impact to the head (Kievit et. al, 2016).There are several examples that could result in a potential TBI; such as falling with contact to the head, car accidents and even physical activities including football, wrestling, and boxing. Because of the several different scenarios that an individual could impact their head, TBI’s have become an all too common aspect of everyday life. TBI is currently the leading cause of death and disability in children and adults under the age of 45, …

Rural Drug Addiction Research Center, Paige Debrie

UCARE: Research Products

Our objective over the course of the summer and the school year was to help develop a new branch of the REACH Lab called Rural Drug Addiction Research center. This branch consisted mainly with the usage of drugs across the midwest. It wasn't until 2018 that the drug crisis hit the midwest increasing by 48% bringing attention to rural drug use. We were here to help translate those findings into something the more general public would understand as well as help with spreading awareness to the community.

Using Electrocoagulation To Remove Perfluoroalkyl And Polyfluoroalkyl Substances (Pfas) From Contaminated Water, Amy Yanagida

UCARE: Research Products

Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) are a family of manmade chemicals that are used to improve the quality of several commercial products by making them resistant to heat, oil, stains, grease and water. Unfortunately, the chemical properties that make PFAS useful from an industrial perspective also make them mobile and recalcitrant once released into the environment. We used electrocoagulation to run a direct current through contaminated water to generate a zinc floc to precipiate PFAS out of water.

Racial–Ethnic Disparities In Prediabetes And Diabetes Among Us Adults, Carly Selleck, Jennifer R. Mcatee, Weiwen Chai

UCARE: Research Products

Type-2 diabetes is a chronic metabolic disease affecting more than3 4 million Americans or 10.5% of the population [1]. While almost 90% of people are not aware of their prediabetes status, around 88 million adults are considered to be prediabetic [2]. Without any prevention methods, 70% of prediabetes cases will eventually develop into diabetes[3]. While the development of type-2 diabetes is multifactorial, lifestyle factors such as diet and physical activity as well as socioeconomic (SES) factors such as poverty and education can be main contributors [4]. This study aimed to assess racial-ethnic differences in SES, lifestyle factors and prevalence of …

Media Use And Depression In College Students, Vanessa Woosley

UCARE: Research Products

College offers new experiences but with that new obstacles as well. Research also shows that there has been a growing need for mental health services on college campuses. 96.5% of American households have a television and 98% of college students are on the internet which is higher than non-students. In this paper, I looked at whether or not there was a direct relationship between media consumption (old and new) and depressive symptoms (distress and general health). In addition, I examined possible mediating variables of self-esteem, life satisfaction and stress. Correlation testing and ordinary least-squares regression with multiple models were used. …
