Older Adult Transportation In Rural Communities: Results Of An Agency Survey, James P. Wood, Jeffrey R. Brown, Megan Bond, Vitor Suguri

Journal of Public Transportation

The proportion of people over age 65 is higher in U.S. rural and small communities than in urban or suburban areas. When older adults who reside in these communities retire from driving, they may need to rely on alternative transportation options that exist in urban settings but that might not be provided, might be less accessible, or might be available in a different form in their communities. This paper uses a survey of service providers to identify the types of public transportation options available to older adults residing in these communities, as well as the strategies employed to finance, operate, …

Method Of Supplementing Cytokine, Chemokine And Growth Factors In Donor Human Milk, Maureen E. Groer, Terri Ashmeade

USF Patents

Donor milk has become a standard of care for feeding preterm infants, particularly those with gestational ages of 34 weeks or less, whose mothers are not lactating or not producing sufficient milk quantities. However, prior to distribution, donor milk is required to undergo pasteurization, typically using the Holder method, which is believed to destroy immune proteins in the milk and denature many other proteins. Donor milk has been found to contain concentrations of chemokines, cytokines, and growth factors, evidencing the value of donor milk over formula. In light of the findings, donor milk is supplemented with chemokines, cytokines, and growth …

Reengineering Of Mesh Thesauri For Term Selection To Optimize Literature Retrieval And Knowledge Reconstruction In Support Of Stem Cell Research, Yan Su, James E. Andrews, Hong Huang, Yue Wang, Liangliang Kong, Peter Cannon, Ping Xu

School of Information Faculty Publications

BACKGROUND: PubMed is a widely used database for scientists to find biomedical-related literature. Due to the complexity of the selected research subject and its interdisciplinary nature, as well as the exponential growth in the number of disparate pieces of biomedical literature, it is an overwhelming challenge for scientists to define the right search strategies and quickly locate all related information. Specialized subsets and groupings of controlled vocabularies, such as Medical Subject Headings (MeSH), can enhance information retrieval in specialized domains, such as stem cell research. There is a need to develop effective search strategies and convenient solutions for knowledge organization …

Smoking By Restrained Eaters Following A Food Prime In The Context Of An Alternative Distractor, Michelle Kovacs

USF Tampa Graduate Theses and Dissertations

Prior research found that female smokers with elevated dietary restraint (“high-restrainers”) smoked more after a disinhibiting food event (Kovacs, Correa, & Brandon, 2014). The current study aimed to determine if high-restrainers smoked merely to distract themselves from eating, or if the appetite/weight-control aspects of smoking played a role. Female smokers (N = 128) attended a laboratory session and were randomized to receive a milkshake prime (Prime condition) or not (No-Prime condition). All participants then received ad-lib access to tempting foods, cigarettes, and a computer tablet with internet access. Our main aims were to test the effect of the prime on …

Foraging Choices Of Vampire Bats In Diverse Landscapes: Potential Implications For Land‐Use Change And Disease Transmission, Daniel G. Streicker, Jacob E. Allgeier

KIP Articles

In Latin America, the common vampire bat Desmodus rotundus is the primary reservoir of rabies, a zoonotic virus that kills thousands of livestock annually and causes sporadic and lethal human rabies outbreaks. The proliferation of livestock provides an abundant food resource for this obligate blood‐feeding species that could alter its foraging behaviour and rabies transmission, but poor understanding of the dietary plasticity of vampire bats limits understanding of how livestock influences rabies risk. We analysed individual‐ and population‐level foraging behaviour by applying δ 13 C and δ 15 N stable isotope analysis to hair samples from 183 vampire bats captured …

An Exploration Of Adolescent Obesity Determinants, Anastasia King Smith

USF Tampa Graduate Theses and Dissertations

In 2010, approximately two-thirds of adults and one-fifth of the adolescent population in the United States were considered either overweight or obese, resulting in the United States having the highest per capita obesity rate among all OECD countries. A considerable body of literature regarding health behavior, health outcomes, and public policy exists on what the Centers for Disease Control and Prevention considers an obesity epidemic. In response to the growing problem of childhood obesity, the Child Nutrition and WIC Reauthorization Act of 2004 (CNRA), which required that schools participating in the National School Lunch Program and/or School Breakfast Program have …

An Observational Study Of How Diet Affects The Presence Of Oral Microbiota In Bats, May 2016, Michelle Klausenstock

Monteverde Institute: Tropical Ecology and Conservation

Microbes in the oral cavity utilize exogenous nutrients taken in from their hosts to sustain themselves. As such, a more diverse diet will likely lead to a more diverse bacterial composition content. Oral swabs from bats of the species Dermanura tolteca and Myotis keaysi were taken in order to assess the diversity of the oral cavity between captive and wild individuals and between frugivorous and insectivorous species by culturing and comparing bacterial morpho species. The captive bats were found to have lower diversity of bacteria present than those in the wild and the frugivores were found to have a higher …

Ectomycota Associated With Arthropods From Bat Hibernacula In Eastern Canada, With Particular Reference To Pseudogymnoascus Destructans, Karen J. Vanderwolf, David Malloch, Donald F. Mcalpine

KIP Articles

The introduction of Pseudogymnoascus destructans (Pd) to North America, agent of white-nose syndrome in hibernating bats, has increased interest in fungi from underground habitats. While bats are assumed to be the main vector transmitting Pd cave-to-cave, the role of other fauna is unexplored. We documented the fungi associated with over-wintering arthropods in Pd-positive hibernacula, including sites where bats had been recently extirpated or near-extirpated, to determine if arthropods carried Pd, and to compare fungal assemblages on arthropods to bats. We isolated 87 fungal taxa in 64 genera from arthropods. Viable Pd was cultured from 15.3% of arthropods, most frequently from …

Method For Modulating Canonical Wnt Pathway Using Folate And Inositol, Kersti K. Linask

USF Patents

The canonical Wnt signaling pathway is implicated in wound healing. Administration of a composition having myo-inositol and folic acid upregulates fibronectin and provides the greatest protection in an additive/synergistic manner against adverse Wnt/.beta.-catenin-mediated effects on cell processes relating to cell differentiation, proliferation, and migration that relate to wound healing.

Exploring The Relationship Between Severity Of Illness And Human Milk Volume In Very Low Birth Weight And Extremely Low Birth Weight Infants Over Six Weeks, Shannon Leigh Morse

USF Tampa Graduate Theses and Dissertations

Very low birth weight and extremely low birth weight neonates have tremendous risk of mortality. This is a grave concern; however, survival alone is not the goal of neonatal intensive care. Survival, along with a reduction or elimination of life long morbidity is the aim of neonatal intensive care.

Human milk is known as the best nutrition for babies and a growing body of evidence supports that human milk is critical in helping these fragile neonates mitigate the overwhelming risks they face. Therefore, the purpose of this study was to examine the relationship between neonatal severity of illness and human …

Coral-Associated Bacterial Diversity Is Conserved Across Two Deep-Sea Anthothela Species, Stephanie N. Lawler, Christina A Kellogg, Scott C. France, Rachel W. Clostio, Sandra D. Brooke, Steve W. Ross

Marine Science Faculty Publications

Cold-water corals, similar to tropical corals, contain diverse and complex microbial assemblages. These bacteria provide essential biological functions within coral holobionts, facilitating increased nutrient utilization and production of antimicrobial compounds. To date, few cold-water octocoral species have been analyzed to explore the diversity and abundance of their microbial associates. For this study, 23 samples of the family Anthothelidae were collected from Norfolk (n = 12) and Baltimore Canyons (n = 11) from the western Atlantic in August 2012 and May 2013. Genetic testing found that these samples comprised two Anthothela species (Anthothela grandiflora and Anthothela sp.) and Alcyonium grandiflorum. DNA …

An Altered Sense Of Magnitude: Exploring How The Visual Presentation Of Time, Space, And Numbers Can Influence Consumer Judgments And Behaviors, Marisabel Romero

USF Tampa Graduate Theses and Dissertations

Consumers are constantly evaluating quantitative information, such as the prices of different products, the time spent on an activity, or the distance covered during one day. Substantial research in psychology has demonstrated that judgments of quantity in one dimension (e.g., numbers) influence subsequent judgments on another dimension (e.g., time). The present research contributes to a growing body of work by exploring how the shared representation of time, space, and numbers affects consumer perceptions and behaviors.

My first dissertation essay explores how the organization of time on a spatial plane affects temporal judgments, product evaluations, and intertemporal discounting (i.e., time-space interaction). …

Spiritual Frameworks In Pediatric Palliative Care: Understanding Parental Decision-Making, Lindy Grief Davidson

USF Tampa Graduate Theses and Dissertations

Parents of seriously ill children are charged with making complicated medical decisions, and many of those decisions are made during their children’s hospitalizations. As medical staff seek to support parents, it is important for them to understand what resources parents are drawing upon for decision-making. This project explored parental decision-making by examining the following research questions: RQ1: What resources do parents draw upon to make medical decisions for their seriously ill children? RQ2: How do parents enact their spiritual or religious frameworks in clinical settings when faced with medical decisions for their seriously ill children? Methods of research included ethnographic …

Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Ceramic Proppant, Humairat H. Rahman

USF Tampa Graduate Theses and Dissertations

Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. Male workers (n = 100) from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected …

The Change In Nutritional Status In Traumatic Brain Injury Patients: A Retrospective Descriptive A Retrospective Descriptive Study, Dina A. Masha'al

USF Tampa Graduate Theses and Dissertations

There is a high prevalence in malnutrition among traumatic brain injury (TBI) due to the hypermetabolism and hypercatabolism which develop post injury. Traumatic brain injury patients are different, even among themselves, in their energy requirements and response to nutritional therapy. This implies that there are other factors that affect the energy intake of these patients and enhance the incidence of malnutrition.

This dissertation study examines the nutritional status of TBI patients upon admission to the intensive care unit (ICU) and during their hospital stay to describe baseline status, detect changes in nutritional status over 7 days, and identify the factors …

Costumbres, Creencias, Y “Lo Normal”: A Biocultural Study On Changing Prenatal Dietary Practices In A Rural Tourism Community In Costa Rica, Allison Rachel Cantor

USF Tampa Graduate Theses and Dissertations

This study explores the relationship between tourism, the nutrition transition, and prenatal dietary practices in the Monteverde Zone, Costa Rica. This rural tourism community, located in the central highlands of Costa Rica, has seen rapid growth and development since the tourism boom in the early 1990s, leading to changes in the local food system and increased food insecurity. This investigation added to this work by identifying the ways that prenatal dietary practices have shifted over time in the context of increased tourism and the concomitant nutrition transition, and by describing the relationship between food insecurity and nutritional status among pregnant …

Planning For Climate Change: The Need For Mechanistic Systems-Based Approaches To Study Climate Change Impacts On Diarrheal Diseases, Jonathan E. Mellor, Karen Levy, Julie Zimmerman, Mark Elliott, Jamie Bartram, Elizabeth Carlton, Thomas Clasen, Rebecca Dilingham, Joseph Eisenberg, Richard Guerrant, Daniele Lantagne, James Mihelcic, Kara Nelson

Civil and Environmental Engineering Faculty Publications

Increased precipitation and temperature variability as well as extreme events related to climate change are predicted to affect the availability and quality of water globally. Already heavily burdened with diarrheal diseases due to poor access to water, sanitation and hygiene facilities, communities throughout the developing world lack the adaptive capacity to sufficiently respond to the additional adversity caused by climate change. Studies suggest that diarrhea rates are positively correlated with increased temperature, and show a complex relationship with precipitation. Although climate change will likely increase rates of diarrheal diseases on average, there is a poor mechanistic understanding of the underlying …

Hunting, Food Subsidies, And Mesopredator Release: The Dynamics Of Crop-Raiding Baboons In A Managed Landscape, Rachel A. Taylor, Sadie J. Ryan, Justin S. Brashares, Leah R. Johnson

Integrative Biology Faculty and Staff Publications

The establishment of protected areas or parks has become an important tool for wildlife conservation. However, frequent occurrences of human-wildlife conflict at the edges of these parks can undermine their conservation goals. Many African protected areas have experienced concurrent declines of apex predators alongside increases in both baboon abundance and the density of humans living near the park boundary. Baboons then take excursions outside of the park to raid crops for food, conflicting with the human population. We model the interactions of mesopredators (baboons), apex predators, and shared prey in the park to analyze how four components affect the proportion …

Mechanistic Binding Insights For 1-Deoxy-D-Xylulose-5-Phosphatesynthase, The Enzyme Catalyzing The First Reaction Of Isoprenoid Biosynthesis In The Malaria-Causing Protists, Plasmodium Falciparum And Plasmodium Vivax, Matthew R. Battistini, Christopher Shoji, Sumit Handa, Leonid Breydo, David J. Merkler

Chemistry Faculty Publications

We have successfully truncated and recombinantly-expressed 1-deoxy-D-xylulose-5-phosphate synthase (DXS) from both Plasmodium vivax and Plasmodium falciparum. We elucidated the order of substrate binding for both of these ThDP-dependent enzymes using steady-state kinetic analyses, dead-end inhibition, and intrinsic tryptophan fluorescence titrations. Both enzymes adhere to a random sequential mechanism with respect to binding of both substrates: pyruvate and D-glyceraldehyde-3-phosphate. These findings are in contrast to other ThDP-dependent enzymes, which exhibit classical ordered and/or ping-pong kinetic mechanisms. A better understanding of the kinetic mechanism for these two Plasmodial enzymes could aid in the development of novel DXS-specific inhibitors that might prove useful …

Sizing An Anaerobic Digester In A Rural Developing World Community: Does Household Fuel Demand Match Greenhouse Gas Production?, Ronald Keelan Greenwade

USF Tampa Graduate Theses and Dissertations

Anaerobic digestion is the process by which organic carbon is converted into biogas in the form of carbon dioxide (CO₂) and methane (CH₄). Both of these products are greenhouse gases that contribute to global warming. Therefore if anaerobic reactors are improperly maintained and biogas is leaked or intentionally released into the atmosphere because biogas production exceeds household demand, these reactors may become generators of greenhouse gas emissions instead of sustainable energy producers. The objective of this research was to develop a framework to assess if the demand for biogas by a rural adopter of an anaerobic …

Adoption Of The Sawyer Water Filter In Peru, Stephanie D. Paredes

USF Tampa Graduate Theses and Dissertations

In Peru, lack of water, sanitation, and hygiene (WASH) results in 6,600 deaths per year that represents approximately 3.9% of total deaths. Three thousand and nine hundred of these deaths were due to diarrheal diseases (Prüss-Üstün et al., 2008). Systematic reviews suggest that interventions to improve microbial quality of drinking water are successful in reducing diarrheal diseases (Fewtrell et al., 2005; Clasen et al., 2007; Fry et al., 2013). Interventions for household water treatment and safe storage to ensure safe drinking water reduce diarrhea by 31-52% (WHO/UNICEF, 2013).

Does Physical Fitness Predict The Reading Achievement Of Fifth-Grade Students? The Interaction With Gender, Courtney Lynn

USF Tampa Graduate Theses and Dissertations

States across the nation are facing pressure to meet standards for high stakes testing which is resulting in a decrease in the amount of time allotted to physical education (Ennis, 2006). Although the U.S. Department of Health and Human Services (2008) recommends children engage in 60 minutes or more of physical activity a day, on average, children only receive 30 minutes per day of aerobic exercise (Epstein et al., 2001). Despite this decrease in physical activity, research has shown that physical activity is associated with academic achievement (Ardoy et al., 2013). In addition, physical activity is positively related to physical …
