Characteristics Of 4-H Participants And Their Psychosocial Development, Lauralee Lyons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Volunteerism is an important component in the 4-H program. It was initially used as a method to help agents reach the many youth interested in participating in 4-H. Community service has since become a required component for every club project. Research shows that volunteering can impact youth in many different ways. Other research shows that 4-H youth are more likely to contribute or do some type of community service.

The present study uses the Modified Extended Version of the Object Measure of Ego Identity Status (EOMEIS), the Cognitive Autonomy and Self-Evaluation (CASE) inventory, and an instrument specifically designed to study …

Jack London: Landscape, Love, And Place, Kristin Yoshiko Ladd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Jack London: Landscape, Love, and Place, American Studies theories and methods formed the prime basis for analysis of London's biography, historical context, and literary significance. Particularly, the ideas of agrarianism, the Turner Thesis moment, Western literature, American masculinity, Victorian ideals, and sustainable farm practices in America were used to understand London's motivations for writing and creating his farm, his influence on American literature, and his texts' abilities to open avenues between literature and place-based education. Key concepts that influenced how London's works could be incorporated into and applied to didactic theory included David Sobel's seminal works in place-based education. …

White-Tailed Deer (Odocoileus Virginianus) Positively Affect The Growth Of Mature Northern Red Oak (Quercus Rubra) Trees., R W. Lucas, R Salguero-Gomez, D B. Cobb, Bonnie G. Waring, F Anderson, W J. Mcshea, B B. Casper

Biology Faculty Publications

Understanding and predicting the effects of deer (Cervidae) on forest ecosystems present significant challenges in ecosystem ecology. Deer herbivory can cause large changes in the biomass and species composition of forest understory plant communities, including early life-cycle trees (i.e., seedlings and saplings). Such changes can impact juvenile to adult transitions and the future age structure and species composition of mature forests. Changes to understory vegetation also impact flow of energy and nutrients in forest ecosystems. Studies examining the influence of deer on mature trees, however, are rare and rely on extrapolating effects from early life cycle stages of trees. We …

Older Adolescents’ Self-Determined Motivations To Disclose Their Hiv Status, Ann Gillard, Mark F. Roark

Kinesiology and Health Science Faculty Publications

Disclosure of HIV status is an important topic for youth living with HIV/AIDS, yet theoretical frameworks for understanding HIV disclosure motivations have been poorly applied. Self-determination theory (SDT) proposes that people are at optimal functioning when they are engaging in activities that are interesting and enlivening. This study utilized SDT to understand young adults’ motivations to disclose their HIV status. Interviews and observations were conducted with nine youth aged 17–19 and two adult staff. Results indicate that SDT is useful for understanding types of motivation (i.e., amotivation, controlled, and autonomous motivation) to disclose. Amotivation was the most common type of …

Effect Of Lactose Monolaurate And High Intensity Ultrasound On Crystallization Behavior Of Anydrous Milk Fat, Ashwini Wagh, M. K. Walsh, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

Crystallization behavior of anhydrous milk fat (AMF) was studied with the addition of 0.025 and 0.05 % lactose monolaurate (LML). The crystallization behavior was studied at low (ΔT = 3 °C) and high supercooling (ΔT = 6 °C). Polarized light microscopy and laser turbidimetry indicated a delay in crystallization on addition of 0.025 % and 0.05 % LML or Tween 20 to AMF. High intensity ultrasound (HIU) was applied to AMF samples with 0.05 % LML and lower supercooling (T c = 31 °C; ΔT = 3 °C). HIU application in AMF and AMF + 0.05 % LML induced crystallization …

Physical Properties Of Pectin Aqueous Solutions Containing Sunflower Wax, Erica R. Baümler, Amalia A. Carelli, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

The aim of this study is to investigate the physical properties of aqueous solutions of pectin (PA) containing sunflower wax (SFW), which are used as a basis for producing edible films. The stability and the rheological and microstructural characteristics of SFW/PA mixtures were evaluated. SFW/PA mixtures formed oil-in-water emulsions that were milky and opaque in appearance and were stable towards phase separation. Polarized micrographs revealed the presence of wax crystals, whose size decreased as pectin concentration increased. The rheological behavior of the aqueous solutions of pectin containing different amounts of SFW were best described by the generalized power law model …

Preventing Deer Damage To Your Trees And Shrubs, Megan Schwender, Michael R. Kuhns

All Current Publications

Deer/human conflicts have increased due to growing deer populations, limited resources and suburban development in deer habitat. In winter, deer often browse in residential landscapes. This can be reduced by selecting unpalatable plants, protecting woody plants with burlap or trunk protectors, and using deer repellent. In extreme cases, deer can be completely excluded with a fence.

Megaherbivores And Cattle Alter Edge Effects Around Ecosystem Hotspots In An African Savanna, Lauren M. Porensky, Solveig Franziska Bucher, Kari E. Veblen, Anna C. Treydte, Truman P. Young

Wildland Resources Faculty Publications

Wild mammalian herbivores and cattle are fundamental drivers of African savanna ecosystems and have strong impacts on woody vegetation. However, few experimental studies have investigated the separate and combined influences of different large herbivores on spatial vegetation patterning. In East Africa, temporary cattle corrals (bomas) develop after abandonment into productive, treeless 'glades' that attract both domestic and wild herbivores. Edges of glades exhibit unusually high densities of large trees. We used a long-term, broad-scale manipulative experiment to test whether megaherbivores (elephants and giraffes), wild meso-herbivores (15–1000kg), or cattle caused shifts in woody plant abundances in glate edges. We also examined …

Canopy Reflectance Estimation Of Wheat Nitrogen Content For Grain Protein Management, Dennis L. Wright, V. Philip Rasmussen, R. Douglas Ramsey, Doran J. Baker, Jason W. Ellsworth

Wildland Resources Faculty Publications

The objective of this study is to evaluate remote sensing as a tool for measuring wheat nitrogen (N) content and then demonstrate how that information may be used by crop managers to improve grain protein content. Remote sensing data from aerial and satellite platforms were collected and compared with flag leaf N concentrations. Flag leaf N was significantly correlated with reflectance (r² = 0.52-0.80) during 2002 and 2003. A mid-season application of N increased grain protein in every treatment, but most significantly in the N-stressed treatments. Using remote sensing as a tool, wheat growers can estimate N stress …

Lactate Threshold: Land Versus Water Treadmill Running, Ron T. Garner

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

Aquatic treadmill running has become increasingly popular for rehabilitation and training purposes due to decreased joint impact on the lower extremities, which is beneficial for special populations such as the injured, elderly, arthritic, and obese (Greene et al., 2009; Hall, Grant, Blake, Taylor, & Garbutt, 2004). Accordingly, researchers have compared key differences such as heart rate (HR), oxygen consumption (VO2), respiratory exchange ratio (RER), stride frequency, and rating of perceived exertion (RPE) between land and water running at maximal and submaximal efforts (Brubaker, Ozemek, Gonzalez, Wiley, & Collins, 2011; Rife, Myrer, Feland, Hunter, & Fellingham, 2010; Rutledge, Silvers, Browder, & …

Factors Affecting The Oxidative Stability Of Foods-Interesterified Soybean Oil With High Intensity Ultrasound Treatment And Trona Mineral In Packaged Fresh Meats, Jiwon Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Oxidation leads to rancid flavors or odors in oils and meat and causes discoloration in muscle foods. There is a great concern about economic loss when oxidation is not effectively controlled. Novel processing and storage methods such as ultrasound, interesterification, or gas emitter sachet in meat packaging have been studied to provide desirable quality properties of oils and meat products. However, there are not enough studies to explain their effect on oxidative stability. Better understanding of new techniques is required to manage the oxidative stability and even other quality properties.

High intensity ultrasound is an effective method to improve physical …

Peach Fruit Quality Analysis In Relation To Organic And Conventional Cultivation Techniques, Varun Chandra Koneru

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The USA is the third major world producer of peaches but consumption has decreased over the last two decades. Consumers have cited mealy texture, fruit browning and lack of sweetness as some undesirable characteristics in peaches, which may be related to the decline. The focus of this study was to evaluate the effect of farm management practices on fruit quality. Physical parameters (color, firmness and size), volatiles and metabolite data was collected.
Sensory evaluation indicated transitional organic peaches were liked the best and organically grown peaches were least liked. All the treatments were significantly different from each other and consumers …

The Micronutrient Profile Of The Typical American Diet Enhances Colorectal Carcinogenesis, Stephany Del Carmen Perez Monsanto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The typical Western dietary pattern is characterized by the consumption of energy-dense, nutrient-poor foods and has been linked to increased risk of colorectal cancer (CRC). Our research group previously developed the total Western diet (TWD) that emulates typical human dietary intakes of macro- (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) on an energy density basis for rodents. In the present study, we sought to determine the impact of TWD on biomarkers of metabolic syndrome and obesity in comparison to a commercial 45% fat diet used for models of diet-induced obesity (DIO diet) and the standard basal AIN93G diet, …

Physiological Response Of Kentucky Bluegrass Under Salinity Stress, Lijun Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salinity is a significant stress for plants world-wide. In agriculture, salts reduce germination, overall growth, yield, and sometimes death in crop plants. Salinity similarly affects turfgrass in our urban landscapes. Kentucky bluegrass (Poa pratensis L.) is the most widely used cool-season grass in the northern part of the United States, including the cool-arid West, but generally is a salt sensitive species. The overall objectives of this study were to study the physiological responses of Kentucky bluegrass to salt stress and to evaluate the genetic similarity among the cultivars used in the research.

Fatty Acid Induced Insulin Resistance In The Brain, Hyoung Il Oh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The prevalence of obesity is rapidly increasing; it is now one of the most serious public health problems worldwide. Obesity is thought to reflect the interaction between genetics and modern life style. In particular, high fat diets (HFD) are considered as a major contributing factor to the development of obesity and type 2 diabetes as well as other metabolic disorders such as cardiovascular disease, Alzheimer’s disease and some types of cancer. Recently, it has been suggested that insulin actions in the brain are important in the regulation of energy homeostasis and peripheral metabolism.
