Program Coordinators’ Experiences With Introducing Parent-Focused Health Lessons To A Child-Centered Micronutrient Supplementation Program: An Exploration Of Recent Programmatic Changes In Liahona Children’S Foundation, Shannon Barham

Undergraduate Honors Theses

This paper utilizes survey responses from local coordinators of LCF, an international micronutrient supplementation humanitarian organization, to provide insight into the challenges and personal rewards of providing nutrition education to parents of malnourished children. LCF is based in Utah and operates in 19 countries throughout the world. LCF recently introduced a series of health lessons geared toward parents of malnourished children. A survey was sent to LCF workers in 12 countries in order to gather feedback about the health lessons. Qualitative survey responses are explored, and potential suggestions for future changes to the health lessons are proposed. Additionally, data gathered …

Department of Food Science and Technology: Faculty Publications

Toll-like receptors (TLRs) play a crucial role in innate immunity and provide a first line of host defense against invading pathogens. Of the identified human TLRs, TLR10 remains an orphan receptor whose ligands and functions are poorly understood. In the present study, we sought to evaluate the level of TLR10 expression in breastmilk (BM) and explore its potential function in the context of HIV-1 infection. We evaluated HIV-1-infected (Nigerian: n = 40) and uninfected (Nigerian: n = 27; Canadian: n = 15) BM samples for TLR expression (i.e., TLR10, TLR2, and TLR1) and report here that HIV-1-infected BM from Nigerian …

Oral History Project (all interviews)

Shirli Self is an Idaho native who has worked in school nutrition both in Idaho and Oregon, in a unique position. The area where she currently works in Oregon is so rural and remote that Oregon pays for her students to finish high school in Idaho after they complete eighth grade in Oregon, because the nearest Idaho high school is much closer than the nearest Oregon high school. She has twenty-one years of school nutrition experience and is a one-woman show, having no employees and being responsible for feeding ninety-three K – 8 students every day.

The chemical profile and antioxidant capacity of Juniperus virginiana, J. excelsa, and J. sabina essential oil (EO) fractions as a function of time was the subject of this study. The hypothesis was that, capturing EO in sequential timeframes during hydrodistillation would generate fractions containing unique compositions and antioxidant capacity. In J. virginiana, the highest limonene (43%) was found in the 0–5 min oil fraction, with safrole (37%) being highest in the 10–20 and 20–40 min fractions, and elemol (34%) being highest in the 160–240 min fraction. In J. excelsa, α-pinene (34-36%) was the highest in the 0–5 min …

Reparation Ecologies: Regimes Of Repair In Populist Agroecology, Kirsten Valentine Cadieux, Stephen Carpenter, Alex Liebman, Renata Blumberg, Bhaskar Upadhyay

Department of Nutrition and Food Studies Scholarship and Creative Works

Amidst the backdrop of attention to populism in general, it is instructive to understand populism through social movements focused on food and agriculture. Agrarian populism is particularly salient in agrifood movements. Agroecology has been widely identified as a domain of populist claims on environmental and social governance surrounding agricultural–ecological and political–economic systems. As authoritarian populist leaders gain power throughout the world at a time of expanding economic globalization and contingent socioecological crises, contests over populism in agrifood regimes can highlight current dynamics relevant for formative evaluation of alternative political agroecology strategies and of populist environmental governance more broadly. Can populism …

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for …

The Effect Of Alcohol And Bitterness Levels On Brewing Yeast Viability, Nichole Elizabeth Bryant

Master's Theses

Two of the most popular beer styles within the craft brewing industry are India Pale Ales (IPA’s) and those with high alcohol by volume (ABV). Production of these styles requires high gravity fermentation and high amounts of bittering hops in order to reach the required values for ABV and International Bitterness units (IBU) respectively. The aim of this study was to determine the impact of high gravity fermentation and high IBU levels on yeast viability and repitching cycles.

An initial experiment on high gravity fermentations was done in order to assess the effects this variable had alone. Successive five day …

A Comparative Analysis Of The Fermentation Capabilities Of Various Bifidobacterium Strains, Ella Oney

Honors Program: Senior Projects (Public)

Bifidobacterium is a genus of anaerobic bacteria that are commonly found to inhabit the gastrointestinal tract of many members of the animal kingdom. These microorganisms are adapted to obtain their carbon from the breakdown of complex carbohydrates. Marmosets, a mammal whose gut microbiome is inhabited by high levels of Bifidobacteria, consume gum Arabic as a major part of their diet. The purpose of this experiment is to determine whether Bifidobacterium strains isolated from the guts of marmosets are able to degrade and ferment this complex carbohydrate or one of its main constituents, arabinose.
