Wetland Mitigation Banking In Tennessee: An Assessment Of Three Banks Performance, Matthew David Skilling

Masters Theses and Doctoral Dissertations

Each year, the nation as a whole loses nearly 58,000 acres of wetlands. The national goal of both the EPA and the Army Corps of Engineers is to achieve no net loss of wetlands. Wetlands law allows for mitigation of wetland impacts with the implied assumption that the mitigation will adequately compensate for the wetland loss. Mitigation banks are becoming a popular mitigation option. Mitigation banks, due to their large size and ample mitigation ratios, make a significant contribution to the national goal of no net loss. This study evaluates three mitigation banks currently operating in Tennessee. The evaluation is …

An Analysis Of The Academic Success Achieved By Five Freshman Cohorts Through A Community College Developmental Education Program., Nancy K. Gray-Barnett

Electronic Theses and Dissertations

The challenge of underprepared students' entering America's colleges and universities is not new. Because of their "open door" policies, community colleges are more likely to enroll students who are not college prepared. This retrospective study focused on the performance of students who had completed required developmental education courses compared to the performance of students without developmental requirements. The study examined developmental education success measures for five cohorts of first-time degree-seeking freshmen each tracked for a six-year period enrolled at Walters State Community College located in Tennessee.

The success measures compared included grade point averages earned in college-level mathematics and English …

Principal Selection And The Stories Superintendents Tell., Linda L. Baker

Electronic Theses and Dissertations

In addition to licensure and certification, there are particular qualities and personal characteristics superintendents look for when hiring a principal. With fewer principal applicants and increased projected needs for principals, it was important to explore the superintendent's reasoning when hiring a principal.

A qualitative research method employing elite interviews was used to explore the criteria that superintendents employ in their process of selecting a principal. When talking about the hiring of principals, superintendents invariably began with the selection process. Teachers, community members, parents, former employers, and college professors gave input in formal or informal ways. Superintendents looked for experience both …

Predicting Risk To Biodiversity As A Function Of Aquifer Pressure In Gab Mound Springs, A. J. Tyre, Brigitte Tenhumberg, H.P. Possingham

School of Biological Sciences: Faculty Publications

Plants and aquatic invertebrates endemic to mound springs of the Great Artesian Basin (GAB) of Australia are of national biodiversity significance. Springs occur in groups, and current survey data suggest that local extinction and recolonisation within a group does occur naturally. Mound spring fauna are therefore good examples of true metapopulations, and any study of the environmental impacts on these systems must take this into account. Use of GAB water leads to drawdown of the pressure in the aquifer. This can potentially impact mound spring flora and fauna in two ways. First, as pressure decreases, so does flow from spring …

Direct Imaging Of Human Swi/Snf-Remodeled Mono- And Polynucleosomes By Atomic Force Microscopy Employing Carbon Nanotube Tips, Gavin R. Schnitzler, Chin Li Cheung, Jason H. Hafner, Andrew J. Saurin, Robert E. Kingston, Charles M. Lieber

Barry Chin Li Cheung Publications

Chromatin-remodeling complexes alter chromatin structure to facilitate, or in some cases repress, gene expression. Recent studies have suggested two potential pathways by which such regulation might occur. In the first, the remodeling complex repositions nucleosomes along DNA to open or occlude regulatory sites. In the second, the remodeling complex creates an altered dimeric form of the nucleosome that has altered accessibility to transcription factors. The extent of translational repositioning, the structure of the remodeled dimer, and the presence of dimers on remodeled polynucleosomes have been difficult to gauge by biochemical assays. To address these questions, ultrahigh-resolution carbon nanotube tip atomic …

Characterization Of Organo-Tin And Organo-Mercury Compounds With Electrospray Mass Spectrometry, Kan Zhu

Masters Theses

Metal-containing compounds are often found as pollutants in the environment. Obtaining speciation information about these compounds is important to understanding toxieity and bioaccumulation. Electrospray Mass Spectrometry (ESMS) is a technique that has the potential to provide rapid and direct speciation information of solution phase metal compounds. The ionization behavior of chemical species is related to their electron affinities. The higher the electron affinity, the easier it will be reduced during the ionization process. Additionally, solvent with different polarity and surface tension will also affect the ionization and reduction products. Organo-tin compounds with more alkyl groups will be ionized more efficiently, …

Pan, Ppn And Mpan Measurements And The Quantitative Relationship Of Pan And Mpan In Biogenic Hydrocarbon Conditions, Chen Wangchun

Masters Theses

Simultaneous measurements of PAN, PPN and MPAN were made during the SOS 1999 Nashville campaign at Dickson site. The PANs data at this site were rich and complex. PAN and MP AN showed obvious diurnal change but PPN did not during this period. PAN and ozone have a clear positive relationship. Due to the special location of the site, winds from different directions bring anthropogenic hydrocarbons (AHCs) or biogenic hydrocarbons (BHCs) to the site. The data showed that the influence of AHCs and BHCs on PANs compounds varied on different days. Average values of PAN/PPN and PAN/MPAN from MLR may …

The Economic Analysis Of Evidence Law: Common Sense On Stilts, Richard O. Lempert

Articles

There was a time when the empire of Law was not overrun by economists. The economists had their own fiefdoms to be sure-there was the Duchy of Antitrust and the Kingdom of Regulatory Law-but the economists lived in peace within these borders, welcoming many unlike themselves into their midst, only gently proselytizing their students in the first few classes of a term, and swearing fealty to the law. It is true that a few marauders from beyond the borders saw the wealth of the empire and sought to colonize it, but even the most daring, Archbishop Coase and Duke Gary …

Solid Waste Management In Oil And Gas Pipelines Application To Asab Field, Abdulqader M Alkamali

Theses

Managing solid waste, and any other wastes in general, is an environmental need, an economical choice and a legal requirement. Preserving the environment while lowering the cost becomes a necessity when liabilities are of concern.

Solid wastes generated from oil and gas industrial activities are very diverse in their characteristics, large in their amounts and many of which are hazardous in nature. Thus, the need to manage these wastes is an obvious mandate. Oil and gas industrial activities include exploration, drilling, production, processing, refining, manufacturing and exporting. Associated with these activities, other supporting services; such as, maintenance, civil, transportation, storage, …

Neuropsychological Functioning And Family Environment Of Children With Attention-Defecit/Hyperactivity Disorder And Comorbid Oppositional Defiant Disorder/Conduct Disorder, M. Catherine Yeager

Theses and Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is hypothesized to be a disorder of executive functioning; however, results of studies comparing ADHD with control children using executive functioning measures are inconsistent, with some studies showing group differences while others do not. One limitation of these studies has been the failure to control for frequently occurring comorbid psychiatric conditions, such as Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD), in the ADHD groups. Previous studies have demonstrated that children with ADHD and comorbid CD or severe ODD perform significantly better on tests of cognitive/executive functioning when compared to children with ADHD only. Based on these …

Large Nondipole Effects In The Angular Distributions Of K-Shell Photoelectrons From Molecular Nitrogen, Oliver Hemmers, H. Wang, P. Focke, I. A. Sellin, Dennis W. Lindle, J. C. Arce, J. A. Sheehy, P. W. Langhoff

Environmental Studies Faculty Publications

Measurements of angular distributions of K-shell electrons photoejected from molecular nitrogen are reported which reveal large deviations at relatively low photon energies ( ħω≤500eV) from emission patterns anticipated from the dipole approximation to interactions between radiation and matter. A concomitant theoretical analysis incorporating the effects of electromagnetic retardation attributes the observed large nondipole behaviors in N₂ to bond-length-dependent terms in the E1⊗(E2,M1) photoelectron emission amplitudes which are indicative of a potentially universal nondipole behavior in molecular photoionization.

Vanderbilt Law School Faculty Publications

This paper documents and explains the amazing growth of the largest firms in law, accounting, and investment banking. Scholars to date have used various supply-side theories to explain the growth, and have generally examined only one industry at a time. We give the first demand-side explanation of firm growth, and show how the explanation is similar for firms in all "project" industries. We show that law plays an important role in determining industry structure. Among the areas we cover are the growth of Multi-Disciplinary Practice firms. We argue that the issues surrounding MDPs can best be understood by looking more …

The Qualitative Report

This study is an assessment of observational learning commonly known as social learning theory of a group of 55 African American students who are participants in a mentoring program known as PROJECT 2000. From first through sixth grades male role models, who were largely African American, were in the classroom as teacher assistants. At the time of the study all student participants were in fifth grade. An interview was conducted featuring a short open-ended questionnaire. Students in PROJECT 2000 had an opportunity to express their feelings about the male role models that worked with them in their classroom. These interviews …

The Impact Of Dismissal Of Non-Tenured Teachers On Principals In Tennessee., David W. Messer

Electronic Theses and Dissertations

The purpose of this study was to examine the issues that principals face in making the decision or recommendation to bring about the involuntary separation of non-tenured teachers. I was concerned with identifying the emotions, feelings, conflicts, and misgivings that principals experience during this process. Related concerns were identified. They included the issues of principals using professionally ethical ways to encourage or coach teachers to resign prior to dismissal, dealing with "lame duck" teachers between notification and the end of the school year, and writing positive letters of recommendation for teachers they have decided not to renew. These questions were …

The Accidental Experts: A Demonstration Of The Existence, Utility, And Emergence Of Implicitly Learned Tacit Knowledge In Assistive-Augmentative Technology Users., Douglas Eugene Masini

Electronic Theses and Dissertations

I investigated the presence, utility, and emergence of tacit knowledge in 9 study participants who used assistive-augmentative technology. I conducted phenomenologic interviews, audio-taping, and transcribed the interview with the written consent of the participants. Sixteen highly trained experts critiqued the final product of the interviews and answered a 25-question survey instrument. Non-parametric statistical processes were chosen to conduct inferential hypotheses testing. Wilcoxon - Mann Whitney U tests and Kruskal - Wallis One-Way ANOVA (alpha level of 0.05) were used for questions 1-10, and a 2 x R (R = 3 or 4) contingency table and Fisher's Exact Chi-Square were used …

Language, Vagueness, And Social Communication, Colin B. Grant

CLCWeb: Comparative Literature and Culture

In his paper, "Language, Vagueness, and Social Communication," Colin B. Grant adopts an interdisciplinary approach to an interrelated complex of language, communication, and society. Grant operates with a modified concept of vagueness as a pragmatic property and attempts to establish a link between pragmatic vagueness and contingency in communication. This communicative contingency takes the form of improbabilities (entropy). Grant observes that the challenge lies in modelling communication as porous networks which nonetheless enable society to function. In this sense, contingency in communication must not be confused with arbitrariness just as cognitive closure cannot be confused with solipsism. This line of …

Pulmonary Arterial Morphometry From Microfocal X-Ray Computed Tomography, Kelly L. Karau, Robert C. Molthen, Anita H. Dhyani, Steven Thomas Haworth, Christopher C. Hanger, David L. Roerig, Roger H. Johnson, Christopher A. Dawson

Biomedical Engineering Faculty Research and Publications

The objective of this study was to develop an X-ray computed tomographic method for pulmonary arterial morphometry. The lungs were removed from a rat, and the pulmonary arterial tree was filled with perfluorooctyl bromide to enhance X-ray absorbance. At each of four pulmonary arterial pressures (30, 21, 12, and 5.4 mmHg), the lungs were rotated within the cone of the X-ray beam that was projected from a microfocal X-ray source onto an image intensifier, and 360 images were obtained at 1° increments. The three-dimensional image volumes were reconstructed with isotropic resolution with the use of a cone beam reconstruction algorithm. …

A New System Of Parallel Isolated Nonthermal Filaments Near The Galactic Center: Evidence For A Local Magnetic Field Gradient, Ted N. La Rosa, Joseph W. Lazio, Nasir E. Kassim

Faculty Articles

We report the discovery of a system of isolated nonthermal filaments approximately 0fdg5 northwest (75 pc in projection) of Sgr A. Unlike other isolated nonthermal filaments which show subfilamentation, braiding of subfilaments, and flaring at their ends, these filaments are simple linear structures and more closely resemble the parallel bundled filaments in the Galactic center radio arc. However, the most unusual feature of these filaments is that the 20/90 cm spectral index uniformly decreases as a function of length, in contrast to all other nonthermal filaments in the Galactic center. This spectral gradient may not be due to simple particle …

Seafloor Characterization From Spatial Variation Of Multibeam Backscatter Vs. Grazing Angle, Tianhang Hou, Lloyd C. Huff, Yuri Rzhanov, Larry A. Mayer

Center for Coastal and Ocean Mapping

Backscatter vs. grazing angle, which can be extracted from multibeam backscatter data, depend on characteristics of the multibeam system and the angular responses of backscatter that are characteristic of different seafloor properties, such as sediment hardness and roughness. Changes in backscatter vs. grazing angle that are contributed by the multibeam system normally remain fixed over both space and time. Therefore, they can readily be determined and removed from backscatter data. The variation of backscatter vs. grazing angle due to the properties of sediments will vary from location to location, as sediment type changes. The sediment component of variability can be …

The Suitability Of Reclaimed Agricultural Lands Along The Lower Colorado River For Native Riparian Habitat Restoration, Patti Aaron

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to determine the suitability of agricultural lands for use in native riparian restoration efforts under development for the Lower Colorado River Multi-Species Conservation Program. Assuming these fields are productive for crops, would they be productive for cottonwood-willow restoration? There are two aspects to consider: (1) the edaphic conditions required for three major LCR agricultural crops; alfalfa, cotton, and wheat, and (2) whether those conditions are consistent with the conditions required for the restoration of native LCR riparian habitat, primarily Fremont cottonwood (Populus fremontii) and Goodding willow (Salix gooddingii). Using the case study research approach …
