The Effect Of Home Health Interventions On Hospital Readmission Rates In Patients With Congestive Heart Failure, Lindsay Reavis May 2018

The Effect Of Home Health Interventions On Hospital Readmission Rates In Patients With Congestive Heart Failure, Lindsay Reavis

Doctor of Nursing Practice Projects

Heart failure is a common diagnosis that affects millions of people worldwide. Unfortunately, heart failure is associated with a high risk of 30-day hospital readmission rates. Home health nurses have the potential to bridge the gap between discharge and hospital readmission by providing up-to-date patient education on a one-to-one basis. Research indicates home health nurses lack knowledge of the disease process, nurse management of the disease, and treatment. This project focused on an educational session about the pathophysiology of heart failure, fluid/weight monitoring, diet, medications, and exercise with a pre- and post-tests evaluating home health nurses understanding of heart failure. …

Establishing Defoliation Thresholds In Peanut (Arachis Hypogaea (L.)) In Mississippi, Chadwick Cameron Abbott

Theses and Dissertations

Foliage feeding insects like fall armyworm (FAW) [Spodoptera frugiperda (J. E. Smith)], granulate cutworm (GCW) [Feltia subterranean (F.)], velvetbean caterpillar (VBC) [Anticarsia gemmatalis (Hübner)] and corn earworm (CEW) [Helicoverpa zea (Boddie)] in peanut (Arachis hypogaea (L.)) and their effects on canopy defoliation and the resultant yield loss is outdated and essentially non-existent in Mississippi. With the expansion of peanuts throughout the state since 2012, growers struggle to manage foliageeeding pests in peanut. The lack of current information regarding insect pressure and economic injury levels is troublesome; especially with newer, high yielding, disease resistant cultivars. Research was required to understand how …


Culture Techniques And Evaluation Of Snail Consumption By Black Buffalo Ictiobus Niger, Emmet Liam Guy May 2018

Culture Techniques And Evaluation Of Snail Consumption By Black Buffalo Ictiobus Niger, Emmet Liam Guy

Theses and Dissertations

Black Buffalo Ictiobus niger are a catostomid species native to the Mississippi River Basin with declining populations. Aquaculture is a common component of recovery plans, however little information is published on catostomid culture methods. This study developed culture techniques for Black Buffalo including tank acclimation, induced spawning, larval rearing, and protein requirements. Fish needed a lengthy acclimation (> 2 months) to reduce signs of stress. After, an induced-spawning protocol was described with gonadotropin-releasing hormone analogue. Swim-up fry did not readily consume zooplankton at first feeding but began selecting for cladocerans one week after stocked in a rearing pond. The juvenile …

A Feel For The Whole: Considering State-Specific Quality Measures For Medicare's Value-Based Programs In The Context Of Social Risk Factors And Population Health, Kimberly K. Roberts

Theses and Dissertations

Healthcare-associated infections (HAIs) are used as a measure for federal value-based payment programs. Using data for 2015, the Centers for Disease Control and Prevention (CDC) developed newer risk adjustment models to calculate the standardized infection ratio (SIR) for various infections occurring in hospitals. New national baselines were set to compare performance among medical facilities and states. Despite adjustments for various facility-level factors that contribute to HAI risk, there are ongoing concerns that SIR calculations do not adequately account for non-hospital risk factors that have been linked to clinical outcomes. This explanatory study evaluates state-level data using simple linear regression to …


A New Perspective On Giving-Up Density Experiments And The Landscape Of Fear, Jordan D. Mcmahon May 2018

A New Perspective On Giving-Up Density Experiments And The Landscape Of Fear, Jordan D. Mcmahon

Theses and Dissertations

Non-consumptive effects that predators have on prey are important to ecosystems. The perceived risk of predation can alter feeding behavior. Giving-up density (GUD) experiments have been a foundational method to evaluate perceived predation risk, but rely on the assumption that food preferences are absolute. However, nutritional preferences are context dependent and can change with risk. In my first chapter, I used spiders and grasshoppers to test the hypothesis that covariance in nutritional preferences and risk may confound the interpretation of GUD experiments. My results demonstrate that predation risk and nutritional preferences covary and can confound interpretation of GUD experiments. In …

The Effects Of Diet, Population, And Water Temperature On The Stress Response Of Angled Largemouth Bass Micropterus Salmoides, Colin P. Dinken

Theses and Dissertations

Angling practices subject Largemouth Bass Micropterus salmoides to multiple stressors, causing homeostatic physiological disturbances. The combined effects of ambient and live well temperature on stress responses from exercise have not been thoroughly examined. Large numbers of fish required for stress experiments can be produced by intensive culture, but hatchery fish may differ physiologically from wild fish due to dietary carbohydrates. Therefore, the effects of diet, population, and temperature on stress response and health were examined. Stress responses were similar among fish fed formulated and live diets and liver health improved within 4-6 weeks. Although cortisol responses of hatchery and wild …


The Effects Of Supplemental Progesterone Via A Cidr Insert On Pregnancy Rates In Dairy Heifer Recipients Of Ivp Embryos, Melissa Steichen May 2018

The Effects Of Supplemental Progesterone Via A Cidr Insert On Pregnancy Rates In Dairy Heifer Recipients Of Ivp Embryos, Melissa Steichen

Theses and Dissertations

In previous research, progesterone has been supplemented using various techniques, at differing time points during peri-insemination in cattle, with conflicting results. Little research has been conducted on the effects of intravaginal delivery of supplemental progesterone following transfer of embryos produced in vitro, and no research was found to investigate this method exclusively in the period post-transfer. Pregnancy rates following the transfer of embryos produced in vitro are considered less than ideal, especially if these embryos have been cryopreserved. Embryos produced in vitro are less equipped to handle the freezing process due to alternative ultrastructural differences, and display lesser developmental potential …

The Importance Of Carbohydrate Timing During High-Intensity Training While Consuming A Low Carbohydrate Diet, Benjamin Michael Krings

Theses and Dissertations

The effects of low carbohydrate (CHO), high fat (LCHF) diets on adaptations to high-intensity exercise have recently gained interest. Consuming a LCHF may potentially decrease the ability to use CHO during exercise and impair high-intensity exercise adaptations. Therefore, the purpose of this investigation was to examine the importance of CHO timing while consuming a LCHF diet and completing a high-intensity exercise program. Eighteen resistance trained males were randomized into two treatment groups. Both groups completed 6 weeks of a high-intensity exercise training program with the first 2 weeks serving as familiarization to resistance training (RT) 3 days per week and …


Nutrients Influence Diet Selection In Herbivores, Jacob Lee Dykes May 2018

Nutrients Influence Diet Selection In Herbivores, Jacob Lee Dykes

Theses and Dissertations

Natural selection should favor selective foraging in deer to choose among nutrients in plant communities to meet their physiological requirements. I designed a two-tier cafeteria-style experiment where I measured plant nutritional quality and white-tailed deer (Odocoileus virginianus) use on 1) 15 species of herbaceous plants, and 2) 2 species of plants of manipulated nutrient concentrations. I tested the hypotheses: 1) deer use across plants would be influenced by plant nutrients, and 2) soil nutrients would influence plant selection by deer. My analyses indicated deer selected plants of low neutral detergent fiber and sulfur concentrations. However, deer selected for crude protein. …

Spatiotemporal Dynamics Of Multi-Scale Habitat Selection In An Invasive Generalist, Kelsey Elizabeth Paolini May 2018

Spatiotemporal Dynamics Of Multi-Scale Habitat Selection In An Invasive Generalist, Kelsey Elizabeth Paolini

Theses and Dissertations

Spatiotemporal dynamics of resource availability can produce markedly different patterns of landscape utilization which necessitates studying habitat selection across biologically relevant extents. Feral pigs (Sus scrofa) are a prolifically expanding, generalist species and researchers have yet to understand fundamental drivers of space use in agricultural landscapes within the United States. To study multi-scale habitat selection patterns, I deployed 13 GPS collars on feral pigs within the Mississippi Alluvial Valley. I estimated resource selection using mixed-effects models to determine how feral pigs responded to changes in forage availability and incorporated those results with autocorrelated kernel density home range estimates. My results …

Morphological Comparison Of Fourth-Instar Larvae From Various Populations Of Wyeomyia Smithii, Kendra D. Moore

Honors College Theses

Populations of pitcher plant mosquitoes, Wyeomyia smithii, have exhibited recent shifts in blood-feeding behavior, likely in response to changes in climate and food availability. A comparison of various morphological structures in fourth-instar larvae was conducted to investigate the hypothesis that geographic and temporal dietary differences are reflected in changes in organismal size.


State Biotechnology Oversight: The Juncture Of Technology, Law, And Public Policy, Christine C. Vito Ph.D. May 2018

State Biotechnology Oversight: The Juncture Of Technology, Law, And Public Policy, Christine C. Vito Ph.D.

Maine Law Review

In a 1980 landmark decision, the Supreme Court of the United States ruled that genetically engineered lifeforms such as bacteria were patentable. The significance of this decision to the emerging biotechnology industry—an industry predicated on intellectual property rights—was incalculable. The characteristically research-intensive, capital-intensive biotechnology industry now had the economic incentive to push the technology of genetic engineering to previously unimagined extremes. The genetic engineering and recombinant DNA applications pursued by the biotechnology industry over the past ten years have engendered a spectrum of perplexing inquiries concerning ethical and moral values; agricultural, ecological and environmental matters; global competitiveness and economic priorities; …

Effects Of Vitamin D Supplementation, Keith R. Anacker, Adarsh K. Gupta

Rowan-Virtua Research Day

Vitamin D (1,25-dihydroxycholecalciferol) is known to be a fat soluble vitamin. We hypothesized that losing weight would thus cause an increase in serum vitamin D levels. To investigate this, a retrospective chart review was performed in which data including sex, age, race, serum Vitamin D levels, body weight and more, of 200 Rowan SOM Family Medicine patients for up to 6 doctor’s office visits each were collected. These data were then analyzed using Microsoft Excel and IBM SPSS. We found while there was a significant positive correlation between weight loss and serum Vitamin D levels, there was not a significant …

Cyanobacteria Reduce Quagga Mussel (Dreissena Rostriformis Bugensis) Spawning And Fertilization Success, Anna G. Boegehold, Nicholas S. Johnson, Jeffrey L. Ram, Donna R. Kashian May 2018

Cyanobacteria Reduce Quagga Mussel (Dreissena Rostriformis Bugensis) Spawning And Fertilization Success, Anna G. Boegehold, Nicholas S. Johnson, Jeffrey L. Ram, Donna R. Kashian

Environmental Science and Geology Faculty Research Publications

Quagga mussels (Dreissena rostriformis bugensis) are highly fecund broadcast spawners invasive to freshwaters of North America and western Europe. We hypothesized that environmental cues from phytoplankton can trigger gamete release in quagga mussels. Nutritious algae may stimulate dreissenid spawning, but less palatable food, such as bloom-forming cyanobacteria, could be a hindrance. The objective of our study was to test whether exposure to cyanobacteria can inhibit quagga mussel spawning and fertilization. We assessed spawning in the presence of serotonin, a known spawning inducer, where adult quagga mussels placed in individual vials were exposed to 13 cyanobacteria cultures and purified algal toxin …


Can Your P2o5 Be Commercially Exploited?, Ewan Wingate, Michael E. Kelahan, M. Robert Kelahan May 2018

Can Your P2o5 Be Commercially Exploited?, Ewan Wingate, Michael E. Kelahan, M. Robert Kelahan

Beneficiation of Phosphates VIII

World reserves of high-grade, high-quality phosphate rock are steadily decreasing. As a result, lower quality rock is being increasingly evaluated to determine its potential for commercial exploitation. It is well known that the chemical and mineralogical composition of phosphate rock varies widely from deposit to deposit, and therefore, the conditions for processing different phosphate rock types also varies.

Unfortunately, most early stage phosphate feasibility studies tend to focus on the P2O5 content and neglect the other chemical constituents or impurities in the rock. It is the remainder of the chemical constituents that often define the quality of …
