The Diets Of Larval And Juvenile Pallid Sturgeon And Shovelnose Sturgeon (Scaphirhynchus Spp.) In The Lower Mississippi River, Audrey Harrison

All Theses

Although North American sturgeon have been the focus of extensive research in the last several decades, more research is essential to ensure their conservation. The free-flowing Lower Mississippi River (LMR) is occupied by two sympatric sturgeon, pallid [ Scaphirhynchus albus (Forbes & Richardson)] and shovelnose sturgeon [Scaphirhynchus platorynchus (Rafinesque)]. These species are considered 'endangered' and 'threatened,' respectively. Recent studies have documented the life history of adult sturgeon in the Mississippi River, but studies focusing on young-of-year and juveniles are limited because young fish are difficult to collect and identifications are problematic. Spawning sites in the LMR are unknown and though …

City Food: Re-Imagining Urban Food Access Through Holistic, Multilayered Typologies Of Urban Agriculture Systems, Tiffany Managad

Effect Of Enzymatic Treatments On The Physiochemical Properties Of Different Corn Starches, Curtis Robert Luckett

Graduate Theses and Dissertations

Amylose readily reassociates to form films and crystalline structures that are resistant to digestion by amylolytic enzymes and known as resistant starch type III (RS3). This study investigated the RS3 formation and cereal coating properties from enzyme-modified corn starches with varying amylose contents, including Hylon VII (70% amylose), Hylon V (50% amylose), and common corn (25% amylose). For RS3 formation, corn starches were first gelatinized and then hydrolyzed using β-amylase to varying degrees. The resultant hydrolyzed starch was debranched with isoamylase and then exposed to 3 times of temperature cycling at 135/133/133°C for 30 min and 95°C for 24 hr …

A Typology Of Preadolescent Sexual Abusers Based On The Emerging Personality Patterns In The Millon Preadolescent Clinical Inventory, Sam Wallace

Graduate Theses and Dissertations

The purpose of this study was to develop a personality-based typology of preadolescents with sexual behavior problems based the Emerging Personality Patterns in the Millon Preadolescent Clinical Inventory (M-PACI, Millon et al., 2005). Grounding a typology in a theory driven personality system may offer clarity and specificity in understanding preadolescents with sexual behavior problems in a manner that has not yet been explored. A personality and theory driven typology could provide a more comprehensive framework for assessing and treating children who sexually abuse than any of the current taxonomic models.

The study used an ex post facto design with test …

Master's Theses or Doctor of Nursing Practice

Eutrophication is a major inland water problem that is researched by many environmentalists and hydrologists. A eutrophic inland water body can cause many negative water problems, such as taste and odor, biotoxin, and low dissolved oxygen. Many previous studies were effective based on using remote sensing to evaluate water body trophic state. In this study, the Cheney Reservoir is selected as an object to test the performance of using remote sensing, specifically the Landsat Thematic Mapper sensor, to evaluate the trophic state of a reservoir. Based on Landsat TM imagery, the chlorophyll a concentration is estimated to be used to …

Promoting Healthy Body Image In College Men: An Evaluation Of A Psychoeducation Program, Justin Henderson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Current psychological research indicates that men are increasingly dissatisfied with their bodies (e.g., McCabe & Ricciardelli 2004; Olivardia, Pope, Borowiecki, & Cohane, 2004). The consequences of body image concerns range from mild discontent (e.g., body dissatisfaction) to the more pathological (e.g., muscle dysmorphic disorder, steroid use, and eating disorders). College-age men are at particular risk of body image disturbances. Drawing from body image research and theory, a one session prevention intervention was designed for college men to address this growing concern. The prevention intervention was intended to serve as a preliminary step into men’s body image prevention programming. The intervention …

Validation Of Thermal Processing To Control Salmonella Spp. And Clostridium Perfringens During Prime Rib Preparation From Intact And Non-Intact Meat, Maria A. Calle

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Beef prime rib is a delicacy cooked at low temperatures for long period and extended hot holding prior to consumption. Due to the potential survival and outgrowth of foodborne pathogens, this process may pose a public health risk. Considering an increase in the availability of non-intact beef, the microbial safety of the preparation of prime rib from intact and mechanically tenderized beef was evaluated.

In the first study, lethality of the prime rib (from intact and non-intact, blade tenderized beef) cooking process to Salmonella spp. was evaluated. Boneless beef rib eye was surface inoculated with a five-strain cocktail of Salmonella …

Modeling Of The Efficacy And Effectiveness Of Escherichia Coli O157:H7 Pre-Harvest Interventions, Amanda R. Vogstad

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Shiga toxin-producing Escherichia coli O157:H7 (STEC O157) is one of the leading causes of hemolytic uremic syndrome in humans. Reducing the prevalence of STEC O157 in live cattle may reduce ground beef prevalence and subsequent human illness. Type III secreted protein vaccines (TTSP) reduce fecal shedding of STEC O157 in cattle. However, pre-harvest vaccines have yet to be adopted by the beef industry. The objectives of this thesis were to 1) conduct a meta-analysis to test factors effecting efficacy of a 3-dose regimen TTSP vaccine product, and 2) use stochastic simulation to model the usefulness of preharvest control measures. In …

Stocking Density Affects Trampling And Use Of Vegetation On Nebraska Sandhills Meadow, Jordan R. Johnson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Ultrahigh stocking density (113,000 kg·ha^-1 to as high as 1 million kg·ha^-1 of beef) or mob grazing has been suggested to build soil, increase forage production and plant diversity, and improve grazing distribution compared to less intensive grazing systems. Experimental evidence does not completely support such conclusions. The overall focus of this research is based on the approach of building soil by optimizing above ground plant growth coming in contact with soil surface by trampling 60% of above ground plant growth. The objective of the study was to compare the effect of mob grazing and simple rotational grazing …

Rankl And Osteoprotegerin Levels In Response To Orthodontic Forces, Katherine Ann Hart D.D.S.

Theses and Dissertations (ETD)

Orthodontic tooth movement is mediated by interactions between PDL cells and those of the alveolus. One protein—the receptor activator nuclear factor kappa B ligand (RANKL)—is critical for osteoclastogenesis, and osteoprotegerin (OPG) is a decoy ligand that competitively inhibits RANKL. A higher RANKL/OPG ratio is associated with areas of bone resorption, while a lower ratio occurs in areas of bone deposition and homeostasis. There have been almost no clinical studies of RANKL and OPG expression in human subjects undergoing orthodontic tooth movement. The purpose of this study was to quantify changes in the levels of RANKL and of OPG expression in …

A Secular Increase In The Tempos Of Tooth Formation: 1980-2010, Kevan Michael O'Neill

Theses and Dissertations (ETD)

Introduction: Improved environments in the U.S. have resulted in taller, larger, and heavier children and adults compared to past generations. Studies of other skeletal-dental dimensions have shown increases across generations, and our perception is that teeth now are forming faster. The purpose of this study is to test for a secular trend towards faster tempos of tooth mineralization in a sample of U.S. white adolescents over the past quarter century (1980-85 to 2005-10).

Materials: Two cohorts of 200 children each were identified, each with an age range of 10-to- 15 years, one group from 1980-85 and the more recent group …

Inequality As A Determinant Of Growth In A Panel Of High Income Countries, Joshua Mcguire

HIM 1990-2015

This paper empirically examines the effect of income inequality on economic growth in a sample of 69 high income economies. It uses an improved inequality dataset developed by the World Institute for Development Economics Research and panel estimation techniques in an ordinary least squares regression. The results provide robust empirical evidence that rising levels of income inequality have adverse effects on growth in high income countries and indicate that, on average, a one standard deviation increase in income inequality will decrease growth by 67.91%. Results from the regression also suggest increases in human capital and international openness, decreases in the …

Health Care Providers' Perspectives On Male Involvement In Their Sexual And Reproductive Health Care Needs, Lilian Milanes

HIM 1990-2015

Young men are at the greatest risk of contracting sexually transmitted infections (STIs) within the U.S. male populations, yet are the least likely to make a sexual and reproductive health (SRH) care visit. Clinical approaches in these areas that include the outreach to and the involvement of male partners of female patients can prove particularly useful in expanding SRH care to men and can also improve health outcomes for women who have sex with men. In this study I examined UCF's healthcare provider's approaches to educate and involve men (between the ages of 18 and 30) and male partners of …
