Pastoral Risk Management In Southern Ethiopia: Observations From Pilot Projects Based On Participatory Community Assessments, D. Layne Coppock, Solomon Desta, Seyoum Tezera, Rancis K. Lelo

Environment and Society Faculty Publications

The Borana pastoral system has come under increasing pressure as human populations grow and per capita availability of resources declines. Livestock exhibit large, periodic die-offs that threaten wealth accumulation and food security. Several types of interventions may improve risk management here. For example, there may be opportunity for some pastoralists to diversify their livelihoods. Here we report on a community-based process involving pilot projects begun since 2000. We have embraced Participatory Rural Appraisal (PRA) and Action Research (AR) as tools for investigation and empowerment of local people. Full PRAs were conducted for semi-settled communities, located near towns, to identify priority …

Analysis Of Phytoplankton Nutrient Limitation In Farmington Bay And The Great Salt Lake, Wayne A. Wurtsbaugh, Amy M. Marcarelli

Watershed Sciences Faculty Publications

The Great Salt Lake is bordered to the south and east by a growing metropolitan area that contributes high nutrients to Farmington Bay. This large bay is eutrophic, and there is concern that continued increases in effluents from the Salt Lake City area could extend to impact the much larger, and currently less productive, Gilbert Bay. This study focused on determining how nutrient supplies might limit, and therefore control, algal populations in Farmington Bay and Gilbert Bay at different salinities. We tested both short and long-term responses of algal growth using laboratory nutrient addition bioassays in the summer and fall …

Diabetes Stepping Up To The Plate: An Education Curriculum Focused On Food Portioning Skills, D. Pauline Williams, Heidi Leblanc, Nedra K. Christensen

Nutrition, Dietetics, and Food Sciences Faculty Publications

The Diabetes Stepping up to the Plate program was developed to determine the effectiveness of food portion based diabetes education. One hundred fifty-one individuals enrolled in the diabetes series. Food portion knowledge and skills tests, height, weight, and waist-to-hip ratio (WHR) were measured pre- and post-program. Data was analyzed through paired t-tests and correlations. Evaluation showed a decrease in HbA1C, waist/hip circumference, WHR, and BMI, and an improvement in food portion knowledge and skills. Seventy-five participants completed pre- and post-data collection parameters, although more participants completed all classes in the series. Extension can play a role in successful diabetes education.

The Evaluation Of A Pulmonary Graphical Display In The Medical Intensive Care Unit: A Feasibility Study, S. Blake Wachter, Dwayne Westenskow

Utah Space Grant Consortium

How a new graphical monitor such as the pulmonary display will be integrated and accepted by the users is an important step when introducing new information and technology in the ICU. We developed a pulmonary display that depicts pulmonary information for an intubated, mechanically ventilated patient. This study observed caregivers attending ICU patients in the presence of the pulmonary display. Attendings observed the pulmonary display an average of 3 times per visit whereas nurses glanced at it at least once per visit. The pulmonary display showed distinct patterns demonstrating the changing underlying pulmonary physiology. Based on analysis of questionnaires, the …

Annual Manure Removal Methods For Manure Storage Facilities, John Harrison

All Archived Publications

A well-designed manure storage facility must also be well managed to prevent environmental concerns from developing. Probably the single most important requirement in operating and maintaining a manure storage facility is to ensure that the facility does not overflow or discharge. Discharges from manure storage facilities may violate local, state, or federal regulations, result in large fines or penalties, and at the very least, represent a potential environmental hazard. Manure removal from storage according to the storage period selected is the most critical activity in preventing discharge. Many discharge problems have occurred because producers were unable to manage the activities …

Antimicrobial Activities Of Lipodepsipeptide Syringopeptins, Mekki F. Bensaci

Biology

Many strains of the plant bacterium Pseudomonas syringae produce two major classes of cyclic lipodepsipeptides, the syringomycins and the syringopeptins. Four groups of small cyclic lipodepsipeptides are well known: the syringomycins, syringostatins, syringotoxins, and pseudomycins. They all have antimicrobial activities and tend to be more active against yeasts than against bacteria. The syringopeptins are lesser-known. The best-studied syringopeptins are SP22 and SP25. They possess antibacterial and antifungal activities, but their mechanisms of action and antimicrobial spectra are less studied. Saccharomyces cerevisiae sphingolipid and sterol biosynthetic mutants were used to investigate the mechanism of action of syringopeptins against fungi. Similarly to …

Assessment Of Calcium, Milk, And Non-Milk Beverage Intake Of Multiethnic Youth Aged 10 To 18 Years, J. Keith Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Achieving and maintaining maximal peak bone mass is critical to the prevention of osteoporosis. Adequate calcium intake during youth is a major aspect of proper bone mass development. Because of the importance of calcium, a food frequency questionnaire (FFQ) that estimates calcium intake of 10- to 18-year-old Asian, Hispanic, and white youth living in the western United States was developed. This new FFQ was shown to accurately and reliably estimate calcium intake of these youth. Accuracy among Hispanics, however, was low and requires further evaluation. A second study examined intake of calcium, milk, and non-milk beverages of Hispanic and non-Hispanic …

Practicum Students' Beliefs About Developmentally Appropriate Practice For Infants And Toddlers, Kaelin Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined practicum students' beliefs and experiences about developmentally appropriate practice (DAP) prior to a practicum experience and following it. Another goal was to examine differences between the practicum students' majors and their pre- and posttest DAP beliefs and experiences scores. Finally, this investigation sought to determine the differences between practicum students' DAP beliefs and experiences and the amount of time they spent in a practicum setting.

A total of 95 students completing a practicum in the Adele and Dale Young Child Development Laboratory in the infant (Group I) or the 2-year-old classroom (Group 2) participated in the study. …

Role Of Iron In The Mechanism Of Asbestos-Induced Apoptosis In Human Lung And Pleural Target Cells, Aleksander Baldys

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Occupational exposure to asbestos has been associated with increased incidence of pulmonary interstitial fibrosis, mesothelioma of the pleura, and bronchogenic carcinoma. Although the mechanism by which asbestos causes cancer remains unknown, iron associated with asbestos is thought to play a role in the pathogenic effects of fibers.

The aim of this research was to examine and compare the asbestos-induced signaling phenomena in relevant human lung and pleural target cells, and to determine the role of iron from asbestos fibers in these events. Exposure of human airway epithelial (A549) cells, human pleural mesothelial (MET5A) cells, and normal human small airway epithelial …

Amazonian Women: A Multi-Voiced Narrative On Surviving Breast Cancer, Melissa Bowles

Undergraduate Honors Capstone Projects

When my mother was diagnosed with breast cancer in May of 2003, I immediately turned to journal writing and to reading to try and make sense of what was happening in my family. I searched websites for causes of breast cancer and ways to prevent it, I read literary women's memoirs, and I wrote a great deal about the way that I was feeling: scared, guilty, angry, broken. As a reader and a writer I needed to somehow intellectualize all of the things I was feeling. This writing project is a product of that initial response and of my subsequent …

The Skull Valley Goshute And Nuclear Waste: Rhetorical Analysis Of Claims-Making Of Opponents And Proponents, Jesse T. Weiss

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the greatest challenges to modem society is the management and disposal of hazardous by-products that have accompanied the industrial advances of the twentieth century. One of the most difficult by-products to deal with has been radioactive waste. Previous research has shown that due to the real and perceived risks associated with this type of waste, the burden of storing said waste has fallen on minority communities, including Native American groups. This research examines the proposed temporary nuclear waste storage facility to be located on the Skull Valley Indian Reservation in Utah. Using an ethnographic case study approach, this …

Multiple Mentors And Family Involvement In Mentoring At-Risk Youth, Christine W. Woodbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined whether higher family involvement plus additional mentoring relationships had a greater positive effect than a one-on-one relationship with a mentor and low family involvement. The study demonstrated, in this sample, that having two mentors does not have a greater impact on academic motivation, social competency, family unity, self-esteem, and deviance than having one mentor. It was also shown, in this sample, that higher family involvement does not have a greater impact on academic motivation, social competency, family unity, self-esteem, and deviance than lower family involvement. Although additional studies are needed to fully understand the impacts of mentoring …

The Effects Of Mortgage Debt On Assets And Total Resources Among Near-Retirement Households, Lance Palmer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the long-term relation between household leverage through the use of mortgages, and changes in household wealth using the theoretical framework of the life cycle income hypothesis. The results of this study are relevant to current positions regarding household leverage via mortgages. This study used the 1992 through 2002 waves of the Health and Retirement Study. The characteristics of leveraged and unleveraged households were compared in 1992 and 2002 as were changes during that period. The relation between household leverage and changes in assets and total resources over the period was modeled using …

Adult Attachment Styles And Their Correlation With Marital Adjustment And Divorce, Cheryl Jones

Undergraduate Honors Capstone Projects

The theory of attachment is a fairly recent approach to studying the relationship between romantic partners. Attachment theory was originally studied to explain the needs and behaviors between infants and their primary caregivers. The attachment style that infants have with their primary caregiver characterizes them throughout their entire lives. Three different styles of attachment have been described: secure, avoidant, and ambivalent. Secure individuals find it easy to get close to others. Avoidant individuals are nervous when people get too close. Ambivalent individuals want to get very close to others and are fearful of abandonment.

Various research studies suggest that attachment …

Identifying And Conceptualizing The Learning Styles Of Youth Referred To The Juvenile Court System, Linda Hall Smith

Undergraduate Honors Capstone Projects

Increasingly youth are being referred to the Juvenile Court for a variety of crimes, including those involving sexually offensive behavior. In the Fall of 2003 the Honorable Judge Gordon Low, of the First District Court in Cache County, State of Utah, requested that a program be developed that would address concerns with regard to the increased frequency of sexually offensive complaints being filed in both the Juvenile, as well as the District Court. His desire was that this program be designed, using an educational format, for youth in Middle and High Schools. Further, it was his intent that it serves …

Women In International Development Theory, Policy And Progress, Melina Tew

Undergraduate Honors Capstone Projects

The Platform for Action of the Fourth World Conference on Women (1995) states: "Equality between women and men is a matter of human rights and a condition for social justice and is also a necessary and fundamental prerequisite for equality, development and peace." As this statement suggests, women are indispensable to any program in the developing world desiring sustainable, effective development. Despite efforts to thwart gender inequality, more women than men still live below the poverty line, and there is a global gender gap in levels of education and access to resources. In response to these conditions, the UN Population …

Undergraduate Honors Capstone Projects

After thorough discussions with my senior academic advisor, Dr. Grange, and the Honors advising department, I decided to conduct my honors senior project on a topic that involved both my educational training and my professional activities. The project addresses the issue that most students outside the college of business do not understand investments. For the past 3 years I have been employed as an intern with Northwestern Mutual Financial Network. In this capacity I have had opportunities to meet with a wide variety of students looking for financial and investment advice. I observed that there was a general lack of …

Unwritten Law: Resilient Management In Latin American Artisanal Fisheries, Brandon Chapman

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Latin American small-scale fishery production is crucial to local communities that count on fish as a key source of protein in daily consumption and for supplying the increasing demand for exported high-value species in the first world. Many small-scale fishing communities have exhibited various forms of informal institutions that serve to manage rights to the fishery, a common-pool resource (CPR). An emerging theme in the CPR management literature is that there are certain types of institutions that exist in successful informal management contexts. Seven case studies from small-scale fishing communities in Latin America are analyzed in order to determine if …

The Robustness Of Factor Analyses When The Data Does Not Conform To Standard Parametric Requirements, Haisong Peng

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Objective: To access the robustness of factor analyses when the data does not conform to standard parametric requirements.

Methods: Data were simulated in package R. Maximum likelihood was used to fit and assess the factor models. Chi-square statistics were obtained to test hypotheses about the correct number of factors in simulated settings where the true number of factors was known. The number of true factors varied between 1 and 3; the number of observed variables was either 6 (for 1 factor) or 3 per factor for 2 or more factors.

Results: With standard normal factor populations, and normal errors added …

Influence Of Sodium Chloride, Calcium, Moisture, And Ph On The Structure And Functionality Of Nonfat Directly Acidified Mozzarella Cheese, Brian M. Paulson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiment A explored the influence of sodium on direct acid, nonfat Mozzarella cheese. Cheeses with differing salt levels were obtained by varying dry salt applications (none, 0.5%, and 1.0% NaCl w/w) and hot brine stretching (0%, 5%, and 10% NaCl wt/v). Salt application and salt content influenced cheese moisture, meltability, expressible serum, micro- and ultra-structure, and color. Moisture was highest when cheese was salted before stretching (P = 0.03). Melt was lowest in cheeses that were unsalted (P = 0.05). Cheeses stretched in salt brine had < 1% of the amount of expressible serum found in unsalted cheese (P < 0.0001). Unsalted cheeses had a more open structure with pockets of serum distributed throughout the protein matrix giving it an opaque, white appearance. Salted cheeses had a more homogeneous protein matrix lacking light scattering surfaces, resulting in a translucent cheese. Neither salt concentration nor method of salting affected the calcium content of the cheeses (P > 0.05).

Experiment B explored the influence of calcium, moisture, and …

Prevention Of Pigment Deterioration And Lipid Oxidation In Ground Beef And Pork, Preetha Jayasingh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fresh beef was modified-atmosphere packaged in carbon monoxide or oxygen to prolong red surface color. After comparison of several packaging method using carbon monoxide, steaks pretreated with 5% carbon monoxide for 24 hours and then vacuum packaged had the best combination of color and microbial stability (5 weeks), with the least potential for carbon monoxide inhalation.

In the evaluation of ground beef in high-oxygen, modified-atmosphere-packaging, thiobarbituric-acid numbers increased over time, and the flavor was disliked slightly after 6 or 10 days of storage at 2° Celsius.

The antioxidant effect of milk-mineral was tested in raw and cooked ground pork stored …

Rapid Detection Of Salmonella Without Enrichment, Emily J. Harrington

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salmonella is one of the leading foodborne pathogens causing illness today. Because of this, Salmonella rapid detection methods are under immense study for use in food. The traditional method, using the Food and Drug Administration- approved Bacterial Analytical Manual procedure, takes 4-6 days for Salmonella detection in food. Other rapid methods still take at least 16 h for detection due to their enrichment steps.

The hypothesis of this study was that the use of immobilized antibodies coupled with polymerase chain reaction (PCR) can be used for the rapid capture and detection of Salmonella spp. in food without the need for …
