Teaching Differential Equations With Graphics And Without Linear Algebra, Nishu Lal, Christopher Towse

CODEE Journal

We present our approach to teaching the Method of Eigenvectors to solve linear systems of ODEs without assuming a prerequisite course in Linear Algebra. Rather we depend heavily on a graphical approach to systems in two dimensions to motivate the eigenvalue equation.

Developmental Regulation Of Phase-I Drug Metabolizing Genes In Mouse Liver, Lai Peng

Doctoral Dissertations

Liver is a critical organ for drug metabolism and is the primary site for the expression of Phase-I drug metabolizing enzymes, which mainly catalyze the oxidation, reduction, and hydrolysis of xenobiotics. However, in the fetus, the major function of liver is hematopoiesis. From infants to adults, dramatic changes occur in liver functions and the Phase-I gene expression, which can markedly affect the metabolism of drugs in newborns and children. Characterization of the expression profiles and regulatory mechanisms of liver development and Phase-I genes is needed for more rational drug therapy of pediatric patients. An animal model is indispensable for studying …

The Library Right There In My Hand: Determining User Needs For Mobile Services At A Medium-Sized Regional University, Paula Barnett-Ellis, Charlcie Pettway Vann

The Southeastern Librarian

While there have been a number of articles written about the need to provide mobile services for users, most have focused on large institutions. The authors, both librarians, wanted to find out how patrons of Houston Cole Library at Jacksonville State University (JSU), a small regional university, are using mobile devices and what mobile services they want or expect from the library. The possibility of finding the answers to these and other questions initiated the authors’ interest in surveying JSU students about their mobile device use. They invited 9,166 students and 1,053 employees to participate in the Mobile Devices Use …

Simulation Of Light Propagation In Skin And Subcutaneous Blood Vessels, Robert Polski, Ricardo Huancaya, Hyun J. Kwon

Posters, Presentations, and Papers

The VeinViewer, produced by the Luminetx Corporation, projects an image of subcutaneous veins onto the surface of the skin by using the discovery that near infrared (NIR) light passes through and transmits back out of the skin issue except at the blood vessels as a result of the presence of hemoglobin¹. We aim to improve the function of the VeinViewer by using computational models to interpret changes in properties of the subject,such as skin pigmentation, and settings on the device, such as light frequency. We also look to decrease error, as a result of the geometry of veins …

Borreliabase: A Phylogeny-Centered Browser Of Borrelia Genomes, Lia Di, Pedro E. Pagan, Daniel Packer, Che L. Martin, Saymon Akther, Girish Ramrattan, Emmanuel F. Mongodin, Claire M. Fraser, Steven E. Schutzer, Benjamin J. Luft, Sherwood R. Casjens, Wei-Gang Qiu

Publications and Research

Background The bacterial genus Borrelia (phylum Spirochaetes) consists of two groups of pathogens represented respectively by B. burgdorferi, the agent of Lyme borreliosis, and B. hermsii, the agent of tick-borne relapsing fever. The number of publicly available Borrelia genomic sequences is growing rapidly with the discovery and sequencing of Borrelia strains worldwide. There is however a lack of dedicated online databases to facilitate comparative analyses of Borrelia genomes. Description We have developed BorreliaBase, an online database for comparative browsing of Borrelia genomes. The database is currently populated with sequences from 35 genomes of eight Lyme-borreliosis (LB) group Borrelia species and …

Foresighting Needs For Secure Societies “2035” – The Focus Roadmap And Its Implications For The Science And Practice Of Politics In Civil Security, Alexander Siedschlag, Andrea Jerković

Publications

There is more than the societal dimension of security: the societal creation of security. There are no effective technological solutions without acceptance and public participation. Security Research should consider significant social, cultural, ethical, legal, and political aspects of security from the very beginning, that is, not only in the implementation perspective and in terms of public acceptance and ascribed legitimacy. Civil security is thus becoming an own sub-field of public policy analysis, addressing societal security from a governance perspective. While “security governance” as such is not a new concept, it so far has mainly been applied to international security and …

Growing Up Beside You: A Relational Sociology Of Early Childhood, Nr Gabriel

Plymouth Institute of Education

This article will begin by outlining influential attempts by historians and sociologists to develop a more adequate theoretical understanding of past and contemporary childhoods, focusing on the major problems that stem from the pivotal role that ‘developmentalism’ plays in their arguments. I will argue that sociologists can overcome some of their deepest fears about the role of developmental psychology by developing a relational approach that integrates the biological and social aspects of children’s development. In the development of a relational sociology of early childhood we need to make important connections with closely related disciplines, but at the same time draw …

Transport Mechanism Of Human Glutamate Transporter Eaat3, Xiaoyu Wang

Open Access Dissertations

Excitatory amino acid transporters (EAATs) remove glutamate from synapses in a reuptake process driven by the Na+ gradient to prevent glutamate concentrations from reaching neurotoxic levels. Malfunction of this reuptake mechanism is implicated in stroke. However, methods to treat glutamate transporter malfunction are limited due to the lack of knowledge of the detailed transport mechanism of these transporters under physiological and pathological conditions. To date no crystal structure of human glutamate transporter is available. All crystal structures of glutamate transporter are from the archaeal glutamate transporter homologue Gltph. Inspection of the available Gltph crystal structures in different states gave rise …

Syndrome Specific And Non-Syndrome Specific Predictors Of Developmental Change In Higher Functioning Children With Autism, Kim E. Ono

Open Access Dissertations

There is a wide range of variability in symptoms and comorbid behaviors among individuals with Autism Spectrum Disorder (ASD). Variability is seen both between individuals at a given point in time and in patterns of change within individuals over time. The goals of the current study were to examine (1) initial levels and rates of change in social reciprocity and internalizing and externalizing behavior problems, and (2) the effects of initial temperament, verbal IQ, and symptom severity on mean initial levels and rates of change in social reciprocity and comorbid internalizing and externalizing behaviors. The sample consisted of higher functioning …

Disturbance Relicts In A Rapidly Changing World: The Rapa Nui (Easter Island) Factor, J. Judson Wynne, Ernest C. Bernard, Francis G. Howarth

KIP Articles

Caves are considered buffered environments in terms of their ability to sustain near-constant microclimatic conditions. However, cave entrance environments are expected to respond rapidly to changing conditions on the surface. Our study documents an assemblage of endemic arthropods that have persisted in Rapa Nui caves, despite a catastrophic ecological shift, overgrazing, and surface ecosystems dominated by invasive species. We discovered eight previously unknown endemic species now restricted to caves—a large contribution to the island’s natural history, given its severely depauperate native fauna. Two additional species, identified from a small number of South Pacific islands, probably arrived with early Polynesian colonizers. …

A Model Of Grammatical Category Acquisition In The Spanish Language Using Adaptation And Selection, Camille Lorraine Judd

Theses and Dissertations

Most typically developing children have achieved a knowledge of the grammatical categories of the words in their native language by school age. To model this achievement, researchers have developed a variety of explicit, testable models or algorithms which have had partial but promising success in extracting the grammatical word categories from the transcriptions of caregiver input to children. Additional insight into children's learning of the grammatical categories of words might be obtained from an application of evolutionary computing algorithms, which simulate principles of evolutionary biology such as variation, adaptive change, self-regulation, and inheritance. Thus far, however, this approach has only …

Synthesis Of [1,2,4]-Triazines As Kinase Inhibitors And Of Novel Fluorine Capture Reagents For Pet Probes, Fenger Zhou

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor, which plays a pivotal part in the development of the central nervous system. Aberrant expression of full-length ALK occurs in neuroblastoma and chromosomal translocation or inversion of the ALK gene can generate novel fusion-ALK proteins that possess constitutive kinase activity and contribute to oncogenic processes. One of the well-studied fusion proteins is nucleophosmin (NPM-ALK), which draws a lot of attention for medicinal chemists to design small molecules as kinase inhibitors for this target. In this dissertation, [1, 2, 4]-Dihydrotriazine dimers as competitors of the lead compound NVP-TAE684 targeting NPM-ALK have …

Metabolomics Analysis Identifies Intestinal Microbiota-Derived Biomarkers Of Colonization Resistance In Clindamycin-Treated Mice, Robin L.P. Jump, Myreen Tomas, Abhishek Deshpande, Curtis J. Donskey

Faculty Scholarship

Background: The intestinal microbiota protect the host against enteric pathogens through a defense mechanism termed colonization resistance. Antibiotics excreted into the intestinal tract may disrupt colonization resistance and alter normal metabolic functions of the microbiota. We used a mouse model to test the hypothesis that alterations in levels of bacterial metabolites in fecal specimens could provide useful biomarkers indicating disrupted or intact colonization resistance after antibiotic treatment. Methods: To assess in vivo colonization resistance, mice were challenged with oral vancomycin-resistant Enterococcus or Clostridium difficile spores at varying time points after treatment with the lincosamide antibiotic clindamycin. For concurrent groups of …

Are Gopher Tortosies (Gopherus Polyphemus Daudin) Comapatible With Cows?, Thomas William Hentges

USF Tampa Graduate Theses and Dissertations

Many Gopher Tortoise populations are in steep decline throughout Florida, and various measures have been attempted to curb the trend. One such measure is to relocate tortoises to protected recipient sites on private lands. The majority of private lands in Florida are used for cattle, however, production and the effect of cattle production on tortoises is not known. Here, I tested six parameters of tortoise behavior by monitoring 1403 gopher tortoises released at the Barthle Brothers Ranch, Pasco County Florida, between August 2009 and December 2012. The parameters tested were (1) burrow density, (2) burrow spacing, (3) burrow relocation, (4) …

Evaluation And Modeling Of Internal Water Storage Zone Performance In Denitrifying Bioretention Systems, Thomas Joseph Lynn

USF Tampa Graduate Theses and Dissertations

Nitrate (NO3) loadings from stormwater runoff promote eutrophication in surface waters. Low Impact Development (LID) is a type of best management practice aimed at restoring the hydrologic function of watersheds and removing contaminants before they are discharged into ground and surface waters. Also known as rain gardens, a bioretention system is a LID technology that is capable of increasing infliltration, reducing runoff rates and removing pollutants. They can be planted with visually appealing vegetation, which plays a role in nutrient uptake. A modified bioretention system incorporates a submerged internal water storage zone (IWSZ) that includes an electron donor to support …

The Impact Of Fear Of Falling On Functional Independence Among Older Adults Receiving Home Health Services, Katherine A. Lawson, Eugenia Catalina Gonzalez

The Open Journal of Occupational Therapy

Background: Falls are the fifth leading cause of death for adults aged 65 years and older. Several intrinsic and extrinsic fall risk factors have been identified, butthere is less understanding of the impact of a fear of falling on falls. Seventy percent of recent fallers and 40% percent of non-fallers report a fear of falling. Therefore, the purpose of this study was to examine the correlation between a fear of falling and a history of falls, as well as the impact on the functional independence of community-dwelling older adults receiving home health services.

Methods: The participants completed the …

The constructs of resilience, the history of resilience theory, models of resilience, variables of resilience, career resilience, and organizational resilience will be examined and discussed as they relate to leadership development. The literature demonstrates that there is a direct relationship between the stress of the leader’s job and his or her ability to maintain resilience in the face of prolonged contact with adversity. This article discusses resilience theory as it relates to leadership development. The concept associated with resilience, which includes thriving and hardiness, …

Nk≠Hpc, P.D. Magnus

Philosophy Faculty Scholarship

The Homeostatic Property Cluster (HPC) account of natural kinds has become popular since it was proposed by Richard Boyd in the late 1980s. Although it is often taken to define natural kinds as such, it is easy enough to see that something's being a natural kind is neither necessary nor sufficient for its being an HPC. This paper argues that it is better not to understand HPCs as defining what it is to be a natural kind but instead as providing the ontological realization of (some) natural kinds.

Tooth Loss Strongly Associates With Malnutrition In Chronic Kidney Disease, Efthimia Effie Ioannidou, Helen Swede

UCHC Articles - Research

Background

In chronic kidney disease (CKD), inadequate nutritional intake, inflammation, and increased oxidative stress have been the major contributing factors in malnutrition pathogenesis. However, there is still a paucity of evidence assessing the magnitude of the effect of tooth loss on malnutrition in CKD populations. The authors hypothesize that among patients with CKD, tooth loss may affect nutritional status, using the National Health and Nutrition Examination Survey 1988 to 1994 (NHANES III).

Methods

Glomerular filtration rate (GFR) was estimated based on cystatin C levels using the relevant equation. Urinary albumin-to-creatinine ratio (albuminuria) was calculated in milligrams per gram with a …

Synthetic Lethality Induced By A Strong Drosophila Enhancer Of Expanded Polyglutamine Tract, Ping Zhang, Qiming Wang, Hannah Hughes, Gino Intrieri

Open Access Author Fund Awardees' Articles

Proteins containing an expanded polyglutamine tract are neurotoxins. The expanded polyglutamine proteins influence a variety of cellular functions. In Drosophila the GMR-Gal4/UAS expression system has been widely used in an eye-based model to study human neurodegenerative diseases. This system has facilitated the isolation and characterization of abundant Drosophilagenes that interact with the expanded polyglutamine proteins. We used the GMR-Gal4/UAS system to express three proteins containing an expanded polyglutamine tract, or an expanded polyglutamine tract alone. Doubling the dose of these proteins resulted in pupal lethality, indicating that these toxic proteins induced a sensitized condition that is prone to synthetic lethality. …
