A Quantitative Examination Of The Relationship Between Servant Leadership And Age On Organizational Commitment In Faith-Based Organizations, Frank Deno

Doctoral Dissertations and Projects

Servant leadership has grown slowly over the past four decades as an organizational style of leadership. Servant leadership is an excellent style for developing followers into their full potential, as it focuses first on the individual, while simultaneously developing capacity to achieve organizational goals. The workforce is constantly circulating, with older workers retiring and younger workers coming into the workforce. There are many factors influencing workers’ commitment to their organization, age is one of these factors and perception of leadership is another. Younger workers have different needs and different motivations than older workers. Faith-based organizations are a smaller segment of …

Nutrient Contamination From Non-Point Sources: Dissolved Phosphate In Surface And Subsurface Waters At Eku Meadowbrook Farm, Madison County, Kentucky, Hunter R. Evans, Reid E. Buskirk, Walter S. Borowski, Jonathan M. Malzone

EKU Faculty and Staff Scholarship

Farms are non-point sources for nutrient contaminants that drain into watersheds and contribute to eutrophication and other environmental problems. Eastern Kentucky University’s Meadowbrook Farm raises both crops and livestock, causing dissolved phosphorus in the form of orthophosphate (PO₄^3-) from fertilizer and animal manure to enter surface and subsurface waters, eventually flowing into Muddy Creek, a tributary of the Kentucky River.

We sampled surface water, springs, and water from French drains that emanate from the farm, and also sampled Muddy Creek waters from May through August 2016. Typically, 1 to 2 days after sampling, we colorimetrically measured dissolved …

Evaluating Long-Term Direct And Correlated Selection Response In White Plymouth Rock Chickens Selected For High Or Low 8-Week Body Weight, Sylvia J. Harrison

Department of Animal Science: Dissertations, Theses, and Student Research

The increasing demand for poultry meat has led animal breeders to engage in artificial selection of chickens as a way to increase the productivity of poultry. Long-term experiments have been designed to measure rates of genetic response to a trait under selection, and correlated traits, as well as gauge possible selection limits.

Two studies were conducted to evaluate response to selection for body weight (BW) in chickens. The chickens were selected for high or low BW at 8 weeks of age. Those that met the criterion were selected as parents for the subsequent generation. In the first study the population …

40Ar/39Ar Ages, Compositions, And Likely Source Of The Eocene Fallout Tuffs In The Duchesne River Formation, Northeastern Utah, Michael Seth Jensen

Theses and Dissertations

Thin fallout tuffs in the Duchesne River Formation in the Uinta Basin, Utah are evidence that volcanism was active in northern Nevada and Utah in the late Eocene. The Uinta Basin is a sedimentary basin that formed during the Laramide orogeny. Ponded lakes of various salinity filled and emptied and during the late Eocene the northern rim was dominated by a wetland/floodplain depositional setting. Most of the tuffs have rhyolitic mineral assemblages including quartz, biotite, sanidine, and allanite. Rhyolitic glass shards were also found in one of the ash beds. Biotite compositions have Fe/(Fe+Mg) ratios typical of calc-alkaline igneous rocks …

Usability Of A Smartphone Application To Support The Prevention And Early Intervention Of Anxiety In Youth, Ryan D. Stoll, Armando A. Pina, Kevin Gary, Ashish Amresh

Publications

Anxiety disorders are among the most common psychiatric problems in youth, fail to spontaneously remit, and place some youth at risk for additional behavioral and emotional difficulties. Efforts to target anxiety have resulted in evidence-based interventions but the resulting prevention effects are relatively small, often weakening over time. Mobile health (mHealth) tools could be of use to strengthen the effects of anxiety prevention efforts. Although a large number of mHealth apps have been developed, few have been evaluated in terms of usability prior to clinical effectiveness testing. Because usability is one of the main barriers to mHealth usage and adoption, …

Framing Genetically-Modified Foods Communication In China: A Content Analysis Of News Coverage Of People’S Daily And Southern Metropolis, Linqi Lu

USF Tampa Graduate Theses and Dissertations

Grounded in framing theory, this thesis presents a qualitative content analysis of newspaper coverage of genetically modified foods by two Chinese newspapers- People’s Daily and Southern Metropolis, in 2000-2017. The political, economic, public opinion and legal implications involved have made the reports of genetically modified (GM) foods present different framing, themes, and positions between People’s Daily and Southern Metropolis. This study aims to examine the various frames used in the coverage of GM foods in two major Chinese newspapers that operate within different media frameworks.

Results of the content analysis illustrated that significant differences existed in the newspapers in …

Thermodynamic And Kinetic Aspects Of Hen Egg White Lysozyme Amyloid Assembly, Tatiana Miti

USF Tampa Graduate Theses and Dissertations

Deposition of protein fibers with a characteristic cross-β sheet structure is the molecular marker associated with human disorders ranging from Alzheimer's disease to type II diabetes and spongiform encephalopathy. Given the large number of non-disease related proteins and peptides that have been shown to form amyloid fibrils in vitro, it has been suggested that amyloid fibril formation represents a generic protein phase transition. In the last two decades it has become clear that the same protein/peptide can assemble into distinct morphologically and structurally amyloid aggregates depending on the solution conditions. Moreover, recent studies have shown that the early stage, oligomeric …

Housing Environment Affects Baseline Anxiety In Zebrafish, Bhavana Movva, Jacob W. Guerrant, Maxwell J. Jentsch, Allison Ogren, Julie L. Mustard, Norbert W. Seidler

Student Publications

Neuroscience researchers that wish to address compelling questions in psychopharmacology would benefit from the use of zebrafish, which have a behavioral repertoire that is rich and complex and that reflects many fundamental processes in humans, such as those that evoke anxiety. Zebrafish behavior is easily quantified in diverse test environments, but it is important to consider the conditions used to house the fish, prior to the behavioral testing, when designing experiments. Studies show that fish housed at high densities exhibit elevated cortisol levels as compared with fish housed at lower densities. The literature is less clear about the behavioral consequences …

South, Olga Igoucheva

Department of Dermatology and Cutaneous Biology Faculty Papers

Hereditary epidermolysis bullosa (EB) is associated with skin blistering and the development of chronic nonhealing wounds. Although clinical studies have shown that cell-based therapies improve wound healing, the recruitment of therapeutic cells to blistering skin and to more advanced skin lesions remains a challenge. Here, we analyzed cytokines and chemokines in blister fluids of patients affected by dystrophic, junctional, and simplex EB. Our analysis revealed high levels of CXCR1, CXCR2, CCR2, and CCR4 ligands, particularly dominant in dystrophic and junctional EB. In vitro migration assays demonstrated the preferential recruitment of CCR4⁺ lymphocytes and CXCR1⁺, CXCR2⁺, …

Temporal Understanding Of Human Mobility: A Multi-Time Scale Analysis, Tongtong Liu, Zheng Yang, Yi Zhao, Chenshu Wu, Zimu Zhou, Yunhao Liu

Research Collection School Of Computing and Information Systems

The recent availability of digital traces generated by cellphone calls has significantly increased the scientific understanding of human mobility. Until now, however, based on low time resolution measurements, previous works have ignored to study human mobility under various time scales due to sparse and irregular calls, particularly in the era of mobile Internet. In this paper, we introduced Mobile Flow Records, flow-level data access records of online activity of smartphone users, to explore human mobility. Mobile Flow Records collect high-resolution information of large populations. By exploiting this kind of data, we show the models and statistics of human mobility at …

Smith, Anuraj H. Shankar, Lee S-F Wu, Said Aboud, Seth Adu Afarwuah, Hasmot Ali, Rina Agustina, Shams Arifeen, Per Ashorn, Arjumand Rizvi

Department of Paediatrics and Child Health

Background: Micronutrient deficiencies are common among women in low-income and middle-income countries. Data from randomised trials suggest that maternal multiple micronutrient supplementation decreases the risk of low birthweight and potentially improves other infant health outcomes. However, heterogeneity across studies suggests influence from effect modifiers. We aimed to identify individual-level modifiers of the effect of multiple micronutrient supplements on stillbirth, birth outcomes, and infant mortality in low-income and middle-income countries.
Methods: This two-stage meta-analysis of individual patient included data from 17 randomised controlled trials done in 14 low-income and middle-income countries, which compared multiple micronutrient supplements containing iron-folic acid versus iron-folic …

Human Trafficking And Pornography: Using The Trafficking Victims Protection Act To Prosecute Trafficking For The Production Of Internet Pornography, Allison J. Luzwick

Northwestern University Law Review

The Trafficking Victims Protection Act of 2000 (TVPA) was passed to “combat trafficking in persons, a contemporary manifestation of slavery whose victims are predominantly women and children, to ensure just and effective punishment of traffickers, and to protect their victims.”1 Since the passing of the Act, federal courts have construed the statute broadly to achieve this stated purpose. One way in which the TVPA has been underutilized, however, is in prosecuting pornography cases. Pornography enjoys wide latitude under the law, protected by a vast net of First Amendment protections. While these protections may preserve freedom of speech, they do nothing …

Spatially Varying Density Dependence Drives A Shifting Mosaic Of Survival In A Recovering Apex Predator (Canis Lupus), Shawn O'Neil, Joseph K. Bump, Dean E. Beyer

Michigan Tech Publications, Part 1

Understanding landscape patterns in mortality risk is crucial for promoting recovery of threatened and endangered species. Humans affect mortality risk in large carnivores such as wolves (Canis lupus), but spatiotemporally varying density dependence can significantly influence the landscape of survival. This potentially occurs when density varies spatially and risk is unevenly distributed. We quantified spatiotemporal sources of variation in survival rates of gray wolves (C. lupus) during a 21-year period of population recovery in the Upper Peninsula of Michigan, USA. We focused on mapping risk across time using Cox Proportional Hazards (CPH) models with time-dependent covariates, thus exploring a shifting …
