The purpose of this study was to determine if specific tasks performed by workers increase concentrations of ammonia and particulate matter exposure.

Methods: An exploratory, descriptive design was used to determine if swine confinement workers have increased ammonia and particulate matter exposure when performing assigned tasks in breeding and gestation barns. A convenience sample of 8 workers volunteered from among all breeding and gestation workers (n=24). Data collection occurred in the morning at each of the 8 farms …

A Qualitative Case Study Of Natural Storytelling Strategies Used At The Nantahala School., Nancy J. Reeder

Electronic Theses and Dissertations

This qualitative case study identifies what 8 teachers naturally do with storytelling at a K-12 school in western North Carolina. Through observations, interviews, field notes, document reviews, and artifact reviews, I used the constant comparison analysis method to discover themes from their formal and informal storytelling strategies. From these themes, I created a framework of 7 suggestions to enhance storytelling awareness. They are: sharing personal stories, developing voice control and body expression, connecting story to school culture, modeling well-developed stories with beginnings, middles, and ends, introducing stories with a pause, expressing the word "imagine" often during instruction, and finally, making …

Teachers' And Students' Perceptions About The Roles Of School Resource Officers In Maintaining School Safety., Sarah Rippetoe

Electronic Theses and Dissertations

According to the National Association of School Resource Officers (2009), every state in the nation employs school resource officers. The trend, which began in 1991, was initially funded by federal monies. Since that time, school resource officers have remained in schools, gaining popularity as a proactive strategy in fighting against school violence. The purpose of the study was to examine students' and teachers' perceptions regarding school resource officers' performance related to the 3 dimensions of their responsibilities: maintaining a safe environment, enforcing the law, and teaching. Data were gathered from 104 teachers and 272 students from a middle school and …

Genetic Structure Of Yonahlossee Salamander Populations., Joshua Andrew Rudd

Electronic Theses and Dissertations

Plethodon yonahlossee is the largest eastern Plethodontid salamander. It has been classified as a species of greatest conservation need by the Tennessee Wildlife Resources Agency (TWRA). Found only in mountainous areas along the borders of Tennessee, North Carolina, and Virginia, populations of the yonahlossee are considered to be rare and local throughout their range. Genetic differentiation among populations of any species is usually attributable to long-standing, extrinsic barriers to gene flow. Because of their disjunct population structure and some observed morphological variation, genetic differentiation among yonahlossee populations is expected. A genetic structure study of yonahlossee was conducted to identify any …

Vitis Seeds (Vitaceae) From The Late Neogene Gray Fossil Site, Northeastern Tennessee, Usa., Fade Gong

Electronic Theses and Dissertations

This study focuses on the morphometric and systematic studies of fossil vitaceous seeds recently recovered from the Gray Fossil Site (7-4.5 Ma, latest Miocene-earliest Pliocene) northeastern Tennessee. Morphologically, all fossil seeds correspond to the extant subgenus Vitis (genus Vitis) of the Vitaceae based on the smooth dorsal surface with a centrally positioned chalaza connected with a conspicuous chalaza-apex groove and short linear ventral infolds that are slightly diverged apically. A multivariate analysis based on 11 measured characters from 76 complete seeds identified three types of seeds, each representing a distinct morphotaxon. Based on comparison with modern and fossil vitaceous …

Reproductive Success Of American Kestrels (Falco Sparverius) Nesting In Boxes Along An Interstate In Northeastern Tennessee., Jennifer Robertson Powers

Electronic Theses and Dissertations

Nest box programs provide supplemental nest sites for American Kestrels, Falco sparverius. When the availability of nest sites is a limiting factor, the addition of nest boxes can increase local breeding populations. These programs also facilitate the collection of data on breeding kestrels.

This study focuses on an American Kestrel (Falco sparverius) nest box trail along Interstate 26 in northeastern Tennessee during the breeding seasons of 1998, 1999, 2000, 2003, 2004, 2006, and 2009.

Investigating Nectar Rhythms In Squash (Cucurbita Pepo): Effects On Honey Bee (Apis Mellifera) Foraging Behavior., Samuel David Boyd

Electronic Theses and Dissertations

Experiments were performed to investigate the influence of water availability on the diel patterns of nectar secretion (volume, concentration, sugar production) in male squash flowers as well as to discover what physical component of nectar honey bees use to trigger their time-memory. Squash plants were grown in the greenhouse and in the field under both constant and variable watering regimes. Throughout anthesis, nectar volume and sugar concentration were recorded. In the field, the temporal distribution of arrivals to squash was observed with and without blossoms present. In the greenhouse and in the field, squash flowers exhibit a consistent diel pattern …

The Influence Of Garden Size And Floral Cover On Pollen Deposition In Urban Community Gardens, Peter A. Werrell, Gail A. Langellotto, Shannon U. Morath, Kevin C. Matteson

Cities and the Environment (CATE)

Many cucurbits, such as cucumbers, squashes and pumpkins, depend on pollinating bees in order to set fruit. However, fruit yield and progeny vigor in these plants generally decreases as heterospecific pollen deposition increases. We studied how the spatial area dedicated to cucumbers (Cucumis sativis), versus other flowering plants, influenced the deposition of conspecific and heterospecific pollen on cucumber plants in New York City community gardens. We also examined the effect of garden size on conspecific and heterospecific pollen deposition on cucumber plants. Female flowers were collected from potted cucumber plants that had been experimentally placed into the gardens, specifically for …

Equipping Children And Pre–Teens To Read And Study Their Bibles, David R. Seal

Christian Perspectives in Education

There is a shortage of material which teaches children and pre–teens how to read and study the Bible. It is important for educators to help them become good Bible readers and interpreters. This paper presents five crucial steps that are important to instruct children and pre–teens in the skills necessary to work out the appropriate meaning and application of the Biblical text. Because children and adolescents learn by “doing,” this article suggests core activities to help them understand and develop Bible interpretation skills.

Community Gardens As Contexts For Science, Stewardship,And Civic Action Learning, Marianne E. Krasny, Keith G. Tidball

Cities and the Environment (CATE)

Community gardens are heterogeneous environments that integrate environmental restoration, community activism, social interactions, cultural expression, and food security. As such, they provide a context for learning that addresses multiple societal goals, including a populace that is scientifically literate, practices environmental stewardship, and participates in civic life. Several theories are useful in describing the learning that occurs in community gardens, including those focusing on learning as acquisition of content by individuals, learning as interaction with other individuals and the environment and as increasingly skilled levels of participation in a community of practice, and social learning among groups of stakeholders leading to …

Bumble Bee Abundance In New York City Community Gardens: Implications For Urban Agriculture, Kevin C. Matteson, Gail A. Langellotto

Cities and the Environment (CATE)

A variety of crops are grown in New York City community gardens. Although the production of many crops benefits from pollination by bees, little is known about bee abundance in urban community gardens or which crops are specifically dependent on bee pollination. In 2005, we compiled a list of crop plants grown within 19 community gardens in New York City and classified these plants according to their dependence on bee pollination. In addition, using mark-recapture methods, we estimated the abundance of a potentially important pollinator within New York City urban gardens, the common eastern bumble bee (Bombus impatiens). …

Manipulating Embryonic Neural Precursor Cells For Therapeutic Transplantation Into A Rat Model Of Neuropathic Pain, Orion Furmanski

Open Access Dissertations

Persons with spinal cord injury (SCI) suffer life-long consequences including paralysis, loss of involuntary bodily functions, and chronic pain. A subset of SCI patients develop neuropathic pain (NP), a chronic condition resulting from damage to the spinal cord. Hyperexcitability of spinal cord sensory neurons near damaged tissue is believed to underlie SCI-related NP. Although many therapies have been employed clinically to combat SCI-NP, few give satisfactory long-term relief. Transplantation of cells that release GABA, a molecule that inhibits neuronal activity, is being explored as an alternative to current SCI-NP therapies. My experiments made progress toward preclinical modeling of GABA cell …

A Multi-Model Approach To Predicting Pathogen Indicator Bacteria Loading In Tmdl Analyses, Donna-May G. Sakura-Lemessy

Open Access Dissertations

This dissertation utilizes data from four sub-watersheds in the Little River Experimental Watershed, GA to develop models to improve forecast predictions related to the management of surface-water pollution due to non-point source runoff. Non-point source pollution is the primary cause of US surface-water quality impairment and a main transport mechanism for pathogens and other pollutants into receiving surface water bodies (US EPA 2008). In response to pollution reduction and watershed remediation mandates under the Federal Clean Water Act (1972)-particularly the Total Maximum Daily Load (TMDL) program-the role of water quality modeling in effectively rehabilitating impaired waters has taken on greater …

Regulation Of Cellular Protein Phosphatase-1 (Pp1) By Phosphorylation Of The Cpi-17 Family, C-Kinase-Activated Pp1 Inhibitors., Masumi Eto

Department of Molecular Physiology and Biophysics Faculty Papers

The regulatory circuit controlling cellular protein phosphatase-1 (PP1), an abundant group of Ser/Thr phosphatases, involves phosphorylation of PP1-specific inhibitor proteins. Malfunctions of these inhibitor proteins have been linked to a variety of diseases, including cardiovascular disease and cancer. Upon phosphorylation at Thr(38), the 17-kDa PP1 inhibitor protein, CPI-17, selectively inhibits a specific form of PP1, myosin light chain phosphatase, which transduces multiple kinase signals into the phosphorylation of myosin II and other proteins. Here, the mechanisms underlying PP1 inhibition and the kinase/PP1 cross-talk mediated by CPI-17 and its related proteins, PHI, KEPI, and GBPI, are discussed.

Copyright For A Social Species, Robert E. Suggs

Faculty Scholarship

Arguments about the proper scope of copyright protection focus on the economic consequences of varying degrees of protection. Most analysts view copyright as an economic phenomenon, and the size and health of our copyright industries measure the success of copyright policies. The constitutional text granting Congress the copyright power and the nature of special interest lobbying naturally create this economic focus; but this is a serious mistake. An exclusively economic focus makes no more sense than measuring the nutritional merits of our food supply from the size and profitability of the fast food industry.

The expressive culture that copyright protects …

Can Green Roofs Provide Habitat For Urban Bees (Hymenoptera: Apidae)?, Sheila R. Colla, Erin Willis, Laurence Packer

Cities and the Environment (CATE)

Increasing urbanization of many regions of the world has resulted in the decline of suitable habitat for wild flora and fauna. Green roofs have been suggested as a potential avenue to provide patches of good-quality habitat in highly developed regions. In this study, we surveyed green roofs in Toronto, Ontario, Canada for bee diversity and abundance to determine their potential as quality habitats in an urban area for these important pollinators. By comparing various biodiversity measures between green roofs and ground-level sites, we show that green roofs provide habitat to many bee species. Implications for pollinator conservation and urban agricultural …

April (Tnfsf13) In Th1, Th2 And Th17 Responses, Yanping Xiao

Open Access Dissertations

The T cell function of a proliferation inducing ligand (APRIL or TNFSF13) remains unclear. By comparing APRIL-/- mice with wild type (WT) mice, we have investigated the roles of APRIL in Th1, Th2 and Th17 responses. With regard to APRIL in Th1 responses, cultured APRIL-/- CD4+ T cells showed increased IFN-gamma production under non-polarizing, but not under Th1 polarizing, conditions. No difference in antigen-specific IgG2a levels existed between APRIL-/- and WT mice immunized with ovalbumin (OVA) and complete Freund's adjuvant (CFA) which induces Th1 polarization. Our data indicate that APRIL represses Th1 responses only under non-polarizing conditions. As for APRIL …

Biology Of Amacrine Cells And Retinal Ganglion Cells In The Developing Retina, Noelia J. Kunzevitzky

Open Access Dissertations

How do neighboring neurons differ? How are they similar? How do they relate to each other? Retinal ganglion cells (RGCs) and amacrine cells are born during the same developmental window, from the same population of progenitor cells, and some amacrine cells even migrate to the same retinal layer where RGCs reside, the ganglion cell layer. Amacrine cells are presynaptic to RGCs, whose axons subsequently project through the optic nerve and carry visual information to the brain. Although the cell biology of RGCs has been studied in some detail, relatively little is known about the cell and molecular biology of amacrine …

Soothability And Growth In Preterm Neonates, Holly Johanna Diesel

Dissertations

This proposal seeks to understand the relationship between soothability, weight gain and length of hospital stay in premature infants when the infants receive a simple, non-invasive treatment to help them cope with the noxious environment of the special care nursery. Thousands of premature infants are born every year in the United States, and the numbers are increasing. Prematurity is the leading cause of mortality in infants. Despite numerous technological and medical advances in treatment and care, premature infants still have difficulty adapting to life outside the uterus as a result of immature nervous systems and significant differences in the pre …
