Although chain quick-service restaurants are required by law to post calorie information on menus and menu boards, the efficacy of menu …

Pickering Stabilization Of Oil-Water Interfaces By Heated B-Lactoglobulin/Pectin Particles, Laura Kathryn Zimmerer

Open Access Theses

The use of natural biopolymer particles as Pickering stabilizers for oil-in-water emulsions was investigated. B-lactoglobulin microgels and B-lactoglobulin/pectin complexes were created by heating appropriate biopolymer solutions at pH 5.8 and 4.75, respectively. Resultant particles exhibited spherical morphology with diameters of 100-300 nm and possessed significant negative surface charge. Particles were first homogenized with 1% corn oil at 0.05%, 0.1% or 0.25% (wt/ wt) particle concentrations. All emulsions appeared stable over seven days with only a thin, creamed ring forming after several hours. Corn oil emulsions were most stable with 0.25% heated complexes, with volume-weighted mean droplet diameter remaining around 480 …

Effects Of Selected Pesticides On Calico Scale And Its Natural Enemies, Carlos Roberto Quesada Machigua

Open Access Theses

Calico scale (Eulecanium cerasorum) is an exotic pest of shade and ornamental trees. It feeds on phloem sap, reduces tree vigor and can ultimately kill trees. We observed effects of four foliar applied (bifenthrin, pyriproxyfen, chlorantraniliprole and cyantraniliprole) and two soil applied pesticides (dinotefuran, imidacloprid) on calico scales and their natural enemies on infested thornless honeylocust trees (Gleditsia triacanthos inermis) over three years. Bifenthrin, dinotefuran and cyantraniliprole provided the largest reductions in scale populations when they were applied to egg laying females on branches early in the season. In contrast, bifenthrin and pyriproxyfen provided the most …

Nutrient Recovery From Anaerobically-Digested Dairy Manure By Struvite Formation And Its Effect On Gas Releases, Zhong Qiao

Open Access Theses

Manure management practices such as anaerobic digestion and lagoon storage have become important issues for large dairy farms partially due to water quality and air quality concerns caused by excess nitrogen and phosphorus. Prior research efforts have proven that struvite formation is an effective method for nutrients recovery from both municipal and agricultural wastewaters. However, little is known about nutrient recovery through struvite formation from anaerobically-digested dairy manure effluents.The effects of struvite precipitation on the releases of gases such as NH3, H2S, and CO2 are also unclear.

In this thesis, both bench-scale tests and pilot-scale storage tests were conducted to …

Omega-3 Fatty Acid Supplementation In The Management Of Chronic Lower Airway Inflammatory Conditions In Horses, Nora Nogradi

The purpose of this study was to evaluate the clinical efficacy of an omega-3 PUFA containing equine feed supplement (Aleira^TM) in horses with chronic lower airway disease. The study consisted of two separate experiments. First, a pilot study was …

Community As Client: Defining Social Design As A Means Of Designing For Good, Ryan Kough Gibboney

Open Access Theses

Approaching the design field today is a significant quantity of societal needs that have potential to be resolved through systematic design initiatives. There is increasing curiosity around the designer's role and responsibility within society; a belief that designers have the power to make social change happen in their own communities. Many neighborhoods with driven community members and professional designers are working together to turn to design as problem solving, as social activism on a local scale. But how do we make this sustainable?

To create a systematic change, designers must rethink the processes in which they view the problems and …

A Guide To Seasonal Migration: Increasing Snowbirds' Longevity, Stephanie Haselkamp, Jenny Styles

Occupational Therapy Capstones

With the demographic shift of the aging population within the United States, and the push for preventative healthcare measures, occupational therapy (OT) practitioners need to adjust the way they are delivering their services to best meet this growing population's needs. Falls prevention is a method for occupational therapists to get involved in preventative care. The need for preventing falls is further supported by the concept of aging-in-place. Aging-in-place is popular amongst the older population, as older adults often wish to remain in their homes and natural contexts for as long as possible. Homes can come in many different forms; and …

Exclusive Breastfeeding Practices Of Mothers In Duakor, A Traditional Migrant Community In Cape Coast, Ghana, Solomon Sika-Bright, Georgina Yaa Oduro

Journal of Global Initiatives: Policy, Pedagogy, Perspective

Ensuring child health and well-being is critical in Ghana’s development. Central to initia-tives for ensuring child health is the World Health Organization’s (WHO) recommended exclusive breastfeeding, which is increasingly being promoted in Ghana. As the name connotes, the practice requires that babies from age zero to six months are breastfed. This practice is however interpreted and practiced differently in line with the traditional mode of feeding babies in most communities in Ghana. This paper presents the findings of a study that examined how mothers breastfeed their babies in the first six months at Dua-kor, a traditional migrant community in Cape …

Rural Women's Role In The Socio-Economic Growth And Well-Being Of Ghana: A Case Study Of Women Operating Within The Informal Sector, Raphael Avornyo

Journal of Global Initiatives: Policy, Pedagogy, Perspective

This paper examines women’s contributions to Ghana’s economic growth and well-being. Data for the study were collected using interviews and focus group discussions (FGDs) with women operating in the informal sector of the Twifo-Hemang-Lower Denkyira District. The main findings of the study showed that even though women con-tribute to socio-economic growth and well-being, most of them do not have adequate ac-cess to the resources needed to expand their impact. The paper recommends policies aimed at addressing women’s issues regarding the socio-economic system, so that they can create wealth and improve well-being for themselves, their children, and society at large.

The Effect Of Health Expenditure And Other Determinants On Health Outcomes, Yi Liu

Theses and Dissertations

A major question in determining health policy is to what extent the additional health care expenditure yields benefits in the form of improved health outcomes. However, establishing relationships between them is very complex, because there are numerous factors besides health expenditure that could contribute to health outcomes, and some data especially individual level nutrition and exercise data, are nearly impossible to gather. Another difficulty involves which indicator we should choose to measure health outcomes.

This study examines life expectancy, all-cause age adjusted mortality rates and infant mortality as the "output" of the health care system, and health expenditure, various life-style, …

The Impact Of Continuous Prenatal And Early Postpartum Maternal Vitamin D Supplementation On The Vitamin D Status Of Exclusively Breastfed Infants, Doria K. Thiele

Theses and Dissertations

In the United States, at least 50% of breastfeeding mothers are vitamin D deficient, increasing risk for vitamin D deficiency in exclusively breastfed infants. A gap in knowledge exists regarding best practices in maternal vitamin D supplementation during pregnancy and lactation that will yield adequate infant vitamin D levels. The objective of this study was to identify the combined effect of maternal prenatal and postnatal vitamin D supplementation on vitamin D transfer to exclusively breastfed infants. Additionally, due to the immune modulating effects of vitamin D, maternal pro- and anti-inflammatory cytokines were measured across pregnancy and the postpartum. A double-blind, …

The decrease in productivity caused by fescue toxicosis has been estimated to cost the United States livestock industry more than $1 billion per year due to reduced growth and diminished reproductive efficiency. This goal of the research presented in this dissertation is to enhance the knowledge base concerning the underlying physiological changes that occur during fescue toxicosis that lead to reduced intake and weight gain in cattle.

As one of the factors associated with fescue toxicosis is a reduction in feed intake, achieving a consistent and adequate intake of toxins can be a complication. Results from experiment 1demonstrate that ruminal …

Evaluation Of The Effects Of Vitamin K On Growth Performance And Bone Health In Swine, James S. Monegue

Theses and Dissertations--Animal and Food Sciences

The role of vitamin K in the blood clotting cascade has been well documented. Vitamin K has recently been implicated in improving bone health. The current studies were conducted to determine the effects of vitamin K in diets with and without mycotoxin contaminated corn on growth performance, bone characteristics, and related blood metabolites in pigs from weaning to market. Menadione sodium bisulfite complex (MSBC, 33% vitamin K) was chosen as the source of supplemental vitamin K because it is the most common form fed to swine. Vitamin K was tested at 0, 0.5, and 2.0 ppm in a corn-soybean meal …

Exploring Linkages Between Consumer Food Co-Operatives And Domestic Fair Trade In The United States, Leslie Duram

Publications

Consumer Food Co-operatives (co-ops) have provided consumers an alternative to corporate supermarkets and big-box stores since the 1960s. Producers seeking broader marketing opportunities often turn to co-ops. This study examines how, within Alternative Food Networks (AFNs), co-ops play a role in the emergence of the Domestic Fair Trade movement in the US. The Domestic Fair Trade (DFT) movement is based on the idea that family farms and small- to mid-sized farms in the global north are facing many of the same pressures as producers in the global south. The Domestic Fair Trade Association (DFTA) in the United States is the …

Ambient Air Pollutant Pm10 And The Risk Of Preterm Birth In Lanzhou, China, Nan Zhao

Public Health Theses

ABSTRACT

Background: Early studies have inconsistently linked ambient air pollutant PM₁₀ exposure during pregnancy to the risk of preterm birth. However, majority of early studies were based on registry data which could result in misclassification of exposure due to the lack of detailed home and work addresses, as well as failed to collect information on potential confounders. China has the world's most polluted cities and suffers the second largest burden of preterm births. Very few studies, however, have been conducted in China to investigate the association between PM₁₀ exposure and preterm birth. Building upon a birth cohort study …

Evaluation Of Effectiveness Of Classroom-Based Nutrition Intervention On Changes In Eating Behavior In African American Parents/Caregivers And Their Children., Nesrine Akil

Wayne State University Theses

Although obesity rate has increased steadily over the past 20 years in the US, a 2006 report showed that the obesity rate is expected to continue to rise, with 13.9% of children between the ages of 2 to 5 years are considered overweight. However, 26.2% were considered at risk of becoming overweight. The parents/caregivers are the key players for developing their children's healthy or unhealthy eating habits since they are the specific determinants of food selection, serving structured meals and being the role models to their children by eating the same food offered themselves. This reflects the parents' significant roles …

Globalization And The Privatization Of Welfare Administration In Indiana, Alfred C. Aman

Indiana Journal of Global Legal Studies

This article explores the relationship of globalization to domestic law in the context of privatized welfare services in Indiana. It examines the ways that privatization can affect vulnerable populations such as welfare recipients by, in effect, partially dis-embedding the market from the state. It applies Karl Polanyi's conception of a double movement to illustrate how the political process can, in effect, re-embed the market in the state. Utilizing Indiana's recent experiences with welfare administration privatization, this article shows that re-embedding is not a simple question of reversing decisions already taken, but rather a complex sequencing of political and legal engagements. …

Techniques To Quantify The Size Of Protein Colloids In Amyloid Fiber Formation, Jonathan R. Anson, Chia-Hung Lu, Lingwen Cui, Xiaojing Yang, Shaohua Xu

Biomedical Engineering and Sciences Faculty Publications

A new method for the analysis of protein colloidal diameter has been developed using three existing protein concentration quantification techniques, absorption at 280 nm, colloidal gold assay, and DC protein assay. Protein colloids are formed in the process of aggregation and are thought to be intermediates in protein self-assembly and formation of amyloid fiber. Deposition of the protein fibers in tissues leads to numerous human diseases including Alzheimer’s. Lysozyme was incubated at pH 2.0, 55°C, an environment conducive to amyloid fiber formation. The protein colloids present in the supernatant of the samples after centrifugation were studied over a time course …

Turkish Journal of Botany

The physiological responses to nitrate stress of 2 transgenic tobacco lines containing the cucumber mitogen-activated protein kinase (CsNMAPK) gene were investigated. Seed germination rates of the transgenic tobacco lines were higher than that of the wild type (WT) tobacco under 150 mM nitrate treatment. The transgenic seedlings had higher root fresh weight (FW) and dry weight (DW) than the WT plants after 98 mM and 182 mM nitrate treatment. The malondialdehyde (MDA) content, electrolytic leakage (EL), and H_{2}O_2 content were higher in the WT than they were in the transgenic plants after 7-day nitrate stress treatment. The antioxidant enzyme (superoxide …

Developing A Durable Right To Health Care, Erin C. Fuse Brown

Faculty Publications By Year

The Patient Protection and Affordable Care Act’s (ACA) signature accomplishment was the creation of a statutory right to health care for the uninsured. This is a momentous change in policy, addressing one of the most vexing social issues of our time and affecting millions of people and billions of dollars of the U.S. economy. This ambition and the degree of societal and political debate leading up to the Act’s passage suggests that it is a “superstatute,” a rare breed of statute that can, among other things, create rights and institutions more typically thought to be the province of constitutional undertaking. …
