Mentoring Nurse Practitioners In A Hospital Setting, Rodica S. Pop

Nursing Dissertations - Archive

In 2009, the American Academy of Nurse Practitioners report identified more than 125, 000 Nurse Practitioners (NP) working in the United States. As the number of NPs increases and their role expands, questions about their work satisfaction and ability to learn and perform the role arise. Since NPs have to combine a nursing philosophy with a medical care model, it is often difficult to mediate the two approaches and fully understand the role. Mentoring has been successfully used to facilitate role transition and role understanding for nurses and physicians, but has been rarely studied in NPs. Although widely used in …

Earth & Environmental Sciences Theses - Archive

An early-Late Pleistocene stalagmite was recovered from Buckeye Creek Cave (37°58.57'N, 80°23.98'W), southeastern West Virginia, USA. The growth axis of stalagmite BCC-025 was sampled for δ18O, δ13C, and Sr/Ca of the calcite. A crude age model was developed using two Th-230 ages, from the top (~490 kyrBP) and bottom (~630 kyrBP) of the stalagmite. A more elaborate age model for stalagmite growth was developed using established marine isotope stage (MIS 13/14, 14/15, 15/16) boundaries. Overall, the MIS boundaries approximate the locations of major hiatuses along the axis of stalagmite growth. The proxy records developed from BCC-025 reveal less covariation and …

On The Existence Of Totally Reflexive Modules, Kristen Ann Beck Jan 2011

On The Existence Of Totally Reflexive Modules, Kristen Ann Beck

Mathematics Dissertations - Archive

In this manuscript, we investigate the existence of non-free totally reflexive modules over two classes of commutative local (Noetherian) rings.First, we demonstrate existence over a class of local rings which are defined by a Gorenstein homomorphism. Among the corollaries to this result, we recover a theorem of Avramov, Gasharov, and Peeva (1997) concerning the existence of non-free totally reflexive modules over local rings with embedded deformations. We also give a general construction for a class of local rings which satisfy the hypotheses of our theorem, and we show it is able to produce rings without embedded deformations.The second focus of …

Chemostratigraphy And Paleoenvironment Of The Smithwick Formation, Fort Worth Basin, San Saba County, Texas, Elisha Nichole Hughes Jan 2011

Chemostratigraphy And Paleoenvironment Of The Smithwick Formation, Fort Worth Basin, San Saba County, Texas, Elisha Nichole Hughes

Earth & Environmental Sciences Theses - Archive

The Early Pennsylvanian-Age Smithwick Formation was deposited in the tectonically active Fort Worth Basin in North Central Texas during a time of well-documented global climatic instability during the Late Paleozoic ice age. Geochemical and stable isotopic results from two cores recovered from the southwestern portion of the FWB provide paleoenvironmental insight into the conditions under which the Smithwick was deposited. Specifically, major element geochemistry and mineralogical results suggest a depositional setting grading from a carbonate-rich facies (Marble Falls and Big Saline) into a transgressive siliciclastic-dominated mudrock (Smithwick) that coarsens upward into a progradational mudrock and silt/sand sequence (Atoka and Strawn). …

Nursing Dissertations - Archive

Gestational diabetes mellitus (GDM) affects over 200,000 women in the United States each year placing them at a sevenfold risk of developing type 2 diabetes mellitus within a decade of delivery as compared to women without GDM. Diabetes has been projected to become more epidemic among women yet, a paucity of research has examined glucose screening trends beyond the postpartum period and longitudinal studies are few among those with a reproductive history of GDM. Suboptimal glucose screening and delayed diabetes detection can lead to an increased risk of cardiometabolic morbidity and mortality. Therefore, this study was designed to examine the …

Intra-Specific Variation Across A Small Temperature Difference In The Spider Rabidosa Rabida (Araneae: Lycosidae) From The Mountains In Arkansas, Ryan Joseph Stork

Biology Dissertations - Archive

Temperature affects all levels of biological organization and ultimately affects multiple aspects of ecological performance and fitness. Generalist arthropod predators are ectothermic and are strongly affected by temperature in ways that are not fully understood. Descriptions of thermal ecology of important generalist arthropod predators are, therefore, essential pieces of information for studying ecology in changing thermal environments. Rabidosa rabida is a wolf spider that inhabits much of the eastern United States and plays an important role as a generalist predator of large herbivorous arthropods. This study makes the first description of the thermal ecology of R. rabida. A description of …

Targeting Of Site-Specific Non-Ltr Retrotransposons: Role Of Amino-Terminal Domains, Haridha Shivram Jan 2011

Targeting Of Site-Specific Non-Ltr Retrotransposons: Role Of Amino-Terminal Domains, Haridha Shivram

Biology Theses - Archive

Restriction-like endonuclease (RLE) bearing non-LTR retrotransposons are site-specificelements that integrate into the genome through target primed reverse transcription (TPRT). RLE-bearing elements have been used as a model system for investigating non-LTR retrotransposon integration. R2 elements target a specific site in the 28S rDNA gene. We previously demonstrated that the two major sub-classes of R2 (R2-A and R2-D) target the R2 insertion site in an opposing manner with regard to the pairing of known DNA binding domains and bound sequences―indicating that the A- and D-clades represent independently derived modes of targeting that site. Elements have been discovered that group phylogenetically with …

Regular Algebras Related To Regular Graded Skew Clifford Algebras Of Low Global Dimension, Manizheh Nafari Jan 2011

Regular Algebras Related To Regular Graded Skew Clifford Algebras Of Low Global Dimension, Manizheh Nafari

Mathematics Dissertations - Archive

M. Artin, W. Schelter, J. Tate, and M. Van den Bergh introduced the notion of non-commutative regular algebras, and classified regular algebras of global dimension 3 on degree-one generators by using geometry (i.e., point schemes) in the late 1980s. Recently, T. Cassidy and M. Vancliff generalized the notion of a graded Clifford algebra and called it a graded skew Clifford algebra.In this thesis, we prove that all classes of quadratic regular algebras of global dimension 3 contain graded skew Clifford algebras or Ore extensions of graded skew Clifford algebras of global dimension 2. We also prove that some regular algebras …

Morphology Of The Lower Missouri River: The Processes Involving Development Of Highly Sinuous Gooseneck Loop Cutoffs Exposed In The Surficial Deposits Of The River Floodplain, Daniel Earl Carlin Jan 2011

Morphology Of The Lower Missouri River: The Processes Involving Development Of Highly Sinuous Gooseneck Loop Cutoffs Exposed In The Surficial Deposits Of The River Floodplain, Daniel Earl Carlin

Earth & Environmental Sciences Theses - Archive

Mapping the surficial deposits of the Missouri River from Sioux City, Iowa to Mondamin, Iowa brought to light a prominent set of landforms exposed in the floodplain and which are also easily visible via aerial photography. The landforms are segments of highly sinuous channel fills that exhibit the characteristic of turning up-dip against the natural southern gradient of the river valley. These prominent channel scars, of which there are only five exposed in the study area, take on a recognizable “gooseneck” shape. The allostratigraphy for the reach of the Missouri River floodplain from Sioux City to Mondamin was mapped during …

Reducing Lead Bioavalability In Soil By Adding Apatite Ii, Dhary Saad Alkandary Jan 2011

Reducing Lead Bioavalability In Soil By Adding Apatite Ii, Dhary Saad Alkandary

Earth & Environmental Sciences Theses - Archive

This study was an examination of phosphate-induced immobilization of lead (Pb) in soils through addition of apatite II (fish bone material). The sources of Pb minerals in the soils examined in this in situ remediation study included anglesite (PbSO4), litharge (PbO), and cerrusite (PbCO3). Phosphate-induced Pb immobilization occurs when Pb ions are exchanged with calcium ions to form insoluble lead-phosphate (pyromorphite (Pb5(PO4)3Cl). Commercially available A- horizon soil was spiked with ten different Pb paints that contained different forms of Pb (e.g. PbO, PbCO3, PbSO4) and then sieved through a <250 micron mesh. Two and three replicates were prepared for each Pb paint sample type for apatite and no apatite additions, respectively. A series of large syringe tubes were filled separately with each of the spiked test soils to create a series of soil columns. In all, a set to sixty seven soil columns amended nominally with 5% w/w of apatite, and 2% Pb paint were tested. The change in potential bioavailability of lead in each soil column was evaluated after each column was eluted with Milli-Q water for one year. Soil samples were taken from each column at times zero, six, and twelve months. An in vitro bioaccessibility assessment of each soil column sample was accomplished using a simulated gastric fluid (SGF) digestion to determine the amount of Pb that could potentially be released into solution in the acid conditions in the human stomach. The assay involved using a SGF solution of 100 mL of Milli-Q water, 3 grams of glycine, and hydrochloric acid (HCl) in sufficient quantity to adjust the pH to a value 2.5. To this solution was added 0.5 gram or 1 gram of soil collected at each of the selected time points. Each SGF and soil suspension was tumbled for one hour at 37 °C in a modified Toxicity Characteristic Leaching Procedure (TCLP) system. A Scanning Electron Microscopy (SEM) spectrometer with a Back-Scattered Electron (BSE) detector and an Energy Dispersive X-ray Spectrometer (EDS) was used to obtain photomicrographs of soil samples and to determine the chemical nature of constituent Pb-bearing particles at time zero and at twelve months. A hand-held X-ray florescence (XRF) detector was used to determine the total Pb concentrations in soil samples at time zero. The study found that there was a general reduction in the amount of bioaccessible Pb in the soils at twelve months compared to time zero. This was supported by the identification of Pb-phosphate particle phases in the soils samples at twelve months. The effectiveness of using apatite II to remediate Pb-paint contaminated soil, through the immobilization of Pb through the formation of the sparingly soluble Pb-phosphate mineral pyromorphite (Pb5(PO4)3Cl) appears to be justified.

Due to the characteristics unique to ionic liquids (ILs), they are found in a plethora of applications from simple liquid-liquid extractions to a proposed liquid medium for a lunar telescope. These applications require a thorough knowledge of the physical and chemical properties of ionic liquids and the knowledge to tune the structure to obtain the desired properties. In my dissertation I have described the systematical design and synthesis of a large number of dicationic, trigonal tricationic and linear tricationic ionic liquids. Their physicochemical properties are characterized and the structural variations attributing to the properties such as melting point, thermal stability, …

Trabecular Bone Variation In Mid And Upper Craniofacial Regions Of Four Anthropoids, Leslie Claire Pryor Smith Jan 2011

Trabecular Bone Variation In Mid And Upper Craniofacial Regions Of Four Anthropoids, Leslie Claire Pryor Smith

Sociology & Anthropology Theses - Archive

Some posit that robust supraorbital tori seen in fossil hominin species are an adaptation to hard object feeding, while others believe that supraorbital morphology is overdesigned for mastication in robust species. Strain gage analysis of primate craniofacial regions finds that strain is much lower in the supraorbital region relative to the zygomatic region, however, the mechanisms behind bone adaptation to loads is not fully understood. While variations in cortical bone material properties in a few primate species have been determined, no one has explored the variation in cranial trabecular bone. This study used microcomputed tomography to assess the variation in …

Investigating Juvenile Supervisory Officers' Attitudes At A Texas Juvenile Detention Center, Justin Michael Patrick Regan Jan 2011

Investigating Juvenile Supervisory Officers' Attitudes At A Texas Juvenile Detention Center, Justin Michael Patrick Regan

Sociology & Anthropology Theses - Archive

Punitive and rehabilitative ideologies have traditionally competed to influence correctional policy. The growing emphasis on prisoner rights however, has subtly transformed the mindset of the carceral institution. Juvenile detention officers, the frontline negotiators of these changes in the juvenile justice system, have been the focus of little ethnographical research concerning their ideological orientation or the pressures that shape that outlook. While sociological and criminal justice studies have quantitatively identified a number of individual and organizational factors that affect officers' attitudes, these studies give scant attention to the actual impact of those views on rehabilitative efforts. This paper extends the carceral …

American Sign Language Verb Categories In Constructed Action, K. Larry Rogers Jan 2011

American Sign Language Verb Categories In Constructed Action, K. Larry Rogers

Linguistics & TESOL Dissertations - Archive

The American Sign Language construction commonly known as "role-shift" superficially resembles mimic forms, however unlike mime, role-shift is a type of depicting construction in ASL discourse (Roy 1989). The signer may use eye gaze, head shift, facial expression, stylistic variation, and use of signing space to convey information (Lee 1997). While this construction may involve a level of gesture, it is linguistic in nature (Padden 1990). "Role-shift may be used to recreate the action in a narrative, thus the term: constructed action” (Metzger 1995). This aspect to depict action is the particular focus of this study. Participants were videotaped telling …

A Biochemical Approach To Determine The Target Site Recognition Mechanism Of The R2 Retrotransposable Elements, Blaine K. Thompson

Biology Theses - Archive

Non-LTR Retrotransposons (NLRs) are selfish mobile genetic elements which parasitize the genomes of many organisms including humans. These elements transpose through an RNA intermediate and integrate directly into their genomic site using reverse transcription, a process called Target Primed Reverse Transcription (TPRT). Members of this family of transposons are abundant in the genomes of many eukaryotes including mammals, reptiles, fish, and insects. Several NLR family members such as R2 and NeSL-1 avoid causing deleterious mutations by specifically targeting repetitive genomic loci such as the 28S ribosomal DNA gene and the Spliced leader-1 exon respectively. This literature review focuses on the …

Place-Names, Conquest, And Empire: Spanish And Amerindian Conceptions Of Place In The New World, Gene Rhea Tucker

History Dissertations - Archive

This research corrects the one-sided historiography of toponyms in the New World, which focus only on the European imposition of place-names, viewed by many postmodernist scholars as a way to oppress and suppress the native Indians. Instead this transatlantic dissertation recognizes that the Spanish brought patterns of place-naming created in the Old World over to the New World. The naming of the New World was not a unilateral Spanish undertaking. The Spanish did create new toponyms in the Americas. They described the land, honored their Catholic faith and their nobility, and they transferred Old World place-names to the New World--but …
