Leadership In Computer-Mediated Communication: Implications And Research Directions, Gerard George, Randall G. Sleeth

Research Collection Lee Kong Chian School Of Business

Despite the importance of interpersonal influence processes in computer-mediated communication (CMC) environments, the emergence and functioning of leaders in CMC settings remains unstudied. An initial model and propositions address the possible extension of selected leadership models beyond face-to-face (FTF) communications and into the non-face-to-face CMC environment. We (1) model relevant variables for CMC leadership, (2) briefly review the implications of selected leadership models regarding these CMC variables, and (3) extend leadership models into the CMC sphere.

Three-Body Effects In The Fragmentation Of D2 By Slow, Highly-Charged Xenon, Robert D. Dubois, I. Ali, C. L. Cocke, C. R. Feeler, Ronald E. Olson

Physics Faculty Research & Creative Works

Highly charged xenon ions were used for fragmentation of D₂ and the corresponding kinematic data. five-body classical trajectory Monte Carlo calculations were presented. Two types of three body effects were identified for strong collisions. Interactions between the undissociated molecules and the dipole fields of the projectiles were also found compatible with the fragmentation picture. Quadrupole-like and higher multipole interactions were the result of the differences between the dissociating fragments and the projectile fields.

Remembering North Claiborne: Community And Place In Downtown New Orleans, Daniel Robert Samuels

LSU New Orleans Theses and Dissertations

The construction of Interstate 10 on North Claiborne Avenue in the mid-1960s is seen by many in the historic downtown New Orleans neighborhoods of Treme and the Seventh Ward as a pivotal event in the life of their community. For many years, North Claiborne, with its broad, oak-lined median, had served as an anchor for the social, economic, and cultural life of this predominantly Creole and African American community.

The construction of Interstate 10 radically altered the physical character of North Claiborne. Many of the homes and businesses that lined the street were demolished to accommodate a series of access …

Estimating Budget Relationships With A Leontief Input-Output Model, Guenever L. R. Shariff

Theses and Dissertations

Forty years ago, the Office of the Secretary of Defense proposed using the Leontief input-output model to assess tradeoffs in the Department of Defense's (DoD) budget. We demonstrate that the Leontief input-output model can assess tradeoffs in the Air Force's budget. To increase one part of the Air Force's budget, we need to know the interrelationships between that budget area and the other areas. In this research, we look at different methods of how the functional areas might interact. We demonstrate our methodology on two data sets - DoD and the Air Force aggregate budget data. By looking at how …

Evaluation Of Maternal Serum Triple Screen As An Identifier Of Trisomy 21 Pregnancy, Jonnie Ann Lane

Graduate Theses, Dissertations, and Problem Reports (ETD)

Maternal serum triple screen is used to identify women less than 35 years of age who are at an increased risk of having a fetus with Down syndrome. The screen identifies 5% of women tested as being at an increased risk but only 2--3% of these women actually have a fetus with chromosome abnormalities, indicating a high false positive rate. Medical records for 900 cases referred for maternal serum triple screen and maternal age were reviewed. The percentages of abnormal karyotypes in the two populations were not significantly different from each other or the expected value. While 3% of all …

Synthesis And Characterization Of Metal Oxide Nanoparticles, Heidi Jo Magnone

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nanoparticles of CuO, Co3O4 and Mn5O 8 were prepared via sol-gel chemical routes. Thermal treatments of the gels were used to obtain particles of different sizes, as determined by the widths of the Bragg lines in x-ray diffraction. To prepare CuO nanoparticles, a Cu(OH)2 gel was first produced by reacting copper nitrate with sodium hydroxide, followed by annealing the gel at temperatures between 160°C to 1,000°C to produce particles in the 6 to 36 nm range. Nanoparticles of Co3O4 in the size range of 9 to 45 nm were prepared in an analogous manner by reacting cobalt nitrate and sodium …

Mapping Appalachia, Jennifer Hall Boggess

Graduate Theses, Dissertations, and Problem Reports (ETD)

The complexities of natural and human events that make up the history of a place also create components of its image. Images, even those that are meant to describe limited, specific information, often reveal more than that which they were designed to tell. The maps that have been used in conjunction with traditional notions of landscape painting suggest that there is no single way to understand a place. They also hint of something ineffable but true emerging from their forms. The history of movement of people and natural forces, the arriving and leaving of individuals and cultures change the landscape. …

Commercialism, Subsistence, And Competency On The Western Virginia Frontier, 1765--1800, John M. Boback

Graduate Theses, Dissertations, and Problem Reports (ETD)

Since the early nineteenth century, Americans have frequently associated the pioneers of the Appalachian Mountains with subsistence farming, economic independence, and a certain degree of hostility toward capitalism. This thesis disproves the myth of pioneer self-sufficiency by demonstrating how the men and women who settled in western Virginia during the final third of the eighteenth century used a variety of tactics in their struggle to achieve a competency. Although subsistence activities, such as hunting and farming, undoubtedly held an important place in the backcountry domestic economy, the settlers also interacted with the commercial market as both producers and consumers of …

Effects Of Gender And Gender Role On Cardiovascular Reactivity And Anger Experience During An Interpersonal Interaction, Andria Leigh Black

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined gender and gender role differences in cardiovascular reactivity and anger experience during an interpersonal interaction. Ninety-six participants interacted in dyads (traditional masculine men with traditional feminine women, and androgynous men with androgynous women). Agency (degree of challenge; High versus Low) and Communion (degree of agreement; Agree versus Disagree) were manipulated. Heart rate (HR) and systolic and diastolic blood pressure (SBP and DBP) were assessed. Participants completed questionnaires assessing state and trait anger, and angry thoughts. Traditional women exhibited higher HR during speaking and listening intervals than other groups. Higher levels of state anger were reported for individuals …

Effects Of Pain And Fear Stimulus Intensity Levels On Pain Responding In Chronic Pain Patients, John Thomas Sorrell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fear has been found to increase and decrease pain responding in various contexts, and the effects of fear and pain stimulus intensity levels on pain responding have not been examined. Forty chronic pain patients were exposed to an algometer pressure pain device which stimulated different fingers; there were two levels of pressure pain (i.e., high and low). Also, there were two levels of induced fear (i.e., high and low). Significant main effects of pain stimulus intensity level were found on threshold pain time, tolerance pain time, and self-reports of fear and pain. Also, a significant main effect of gender was …

Solitary Waves And Supersonic Reaction Front In Metastable Solids, Hendrik J. Viljoen, Lee L. Lauderback, D. Sornette

Hendrik J. Viljoen Publications

Motivated by an increasing number of remarkable experimental observations on the role of pressure and shear stress in solid reactions, explosions and detonations, we present a simple toy model that embodies nonlinear elasticity and dispersion as well as chemical or phase transformation. This generalization of the Toda Lattice provides an effective model for the description of the organization during an abrupt transformation in a solid. One of the challenges is to capture both the equilibrium degrees of freedom as well as to quantify the possible role of out-of-equilibrium perturbations. In the Toda Lattice, we verify that the particle velocities converge …

The Unfounded Fear Of Regulation S: Empirical Evidence On Offshore Securities Offerings , Stephen J. Choi

Duke Law Journal

Regulation S provides U. S. issuers with an exemption from the registration requirements of the Securities Act of 1933 to the extent that securities are offered and sold solely outside the United States. Through resales back into the United States, however, U. S. investors may become exposed to unregistered securities initially distributed abroad through Regulation S. This Article identifies two distinct risks from an offshore securities offering. First, issuers may conduct an offering under Regulation S as a means to sell securities indirectly into the United States through resales in situations where the U. S. secondary market overvalues the issuer's …

Role Of ΣB In Adaptation Of Listeria Monocytogenes To Growth At Low Temperature, Lynne A. Becker, Stefanie N. Evans, Robert W. Hutkins, Andrew K. Benson

Department of Food Science and Technology: Faculty Publications

The activity of σ^B in Listeria monocytogenes is stimulated by high osmolarity and is necessary for efficient uptake of osmoprotectants. Here we demonstrate that, during cold shock, σ^B contributes to adaptation in a growth phase-dependent manner and is necessary for efficient accumulation of betaine and carnitine as cryoprotectants.

Surface Segregation And Restructuring Of Colossal-Magnetoresistant Manganese Perovskites La0.65Sr0.35Mno3, Hani Dulli, Peter A. Dowben, Sy-Hwang Liou, E. Ward Plummer

Department of Physics and Astronomy: Faculty Publications

We have investigated the surface chemical composition of crystalline films of La_0.65Sr_0.35MnO₃ by angle-resolved x-ray photoelectron spectroscopy. The surface composition was found to be significantly different from that of the bulk because of an appreciable Sr segregation. Furthermore, our study suggests that this Sr segregation has caused a major restructuring of the surface region characterized by the formation of a Ruddlesden-Popper phase (La,Sr)_n+1Mn_nO_3n+1 with n = 1. Segregation and restructuring in the surface region should be common in these doped perovskites and will have a profound impact on the electronic …

Assessment Of Small Mammal Populations In Two Southeastern Forests Of Big Ridge In Chattanooga, Tn, Melissa R. Dickinson

Masters Theses and Doctoral Dissertations

Field research was conducted to test for effects of urbanization on small mammal abundance and diversity. Preliminary studies were preformed to test sampling techniques and acquire a sample size estimate for the primary study. Sampling sites were chosen in old growth and mixed hardwood forest areas. Six day sampling periods consisted of differing densities and setups of Sherman and pitfall traps within 0.16-ha plots. Data was not statistically analyzed due to minimal sample sizes. Comparable 1.28-ha mixed hardwood forest study sites were chosen in the Big Ridge area of Chattanooga, Tennessee for the primary study. One site had protected status, …

Electronic Theses and Dissertations

Using four surveys, two created by this researcher, another created by Walizcek, Mattson, and Zajicek, and a fourth created by Herbach, the researcher compared the characteristics of community gardeners, their motivations for gardening, and the management practices of the inner-city Limerick Community Garden and the suburban Blackacre Community Garden in Jefferson County, Kentucky. 33 Blackacre gardeners, 16 Limerick gardeners, two garden managers, and two garden administrators participated in the study. The researcher hypothesized that the location of the garden could be influential in determining who the gardeners are and what their motivations for gardening are. The inner-city garden was expected …

Synthesis And Characterization Of Functionalized Zirconium Pendent Polyamic Acids And Polyimides Based On 3,4'-Oda And Odpa, Wei Wang

Theses

The objective of this thesis is to synthesize functionalized zirconium complex pendent polyamic acids and polyimides, then compare their characteristics, e.g. thermal properties, atomic oxygen resistance, and film properties (adhesion, flexibility, and solvent resistance). Towards this end, five different zirconium complexes were attached to the polyamic acid, which is based on 3,4'-oxydianiline (3,4'-0DA), 4,4'-oxydiphthalic anhydride (ODPA), and mellitic dianhydride (MADA), in the presence of dicyclohexylcarbodiimide (DCC). The resulting zirconium complex pendent polyamic acids and the parent polyamic acid were cast onto glass substrates, then thermally imidized by heating at 100C, 200C, and 300C for one hour each. The synthesized zirconium …

Ostensible Abductions, Real Anthropology, Timothy F. Mccauley

Masters Theses

A gap has developed in the research agenda of contemporary anthropology with regard to a phenomenon which has received notable attention from research professionals in other fields, such as history and psychiatry. What has been called the "alien abduction phenomenon" has had considerable impact, not only on those who sincerely believe these events are an everyday part of human experience (called "abductees") but also on the changing tapestry of American culture. Alien abduction accounts are closely related to the Unidentified Flying Object (UFO) phenomenon, a theme which has shaped American culture since the tum of the century. This thesis represents …

Factors Influencing Brook Trout (Salvelinus Fontinalis ) Abundance In Forested Headwater Streams With Emphasis On Fine Sediment, James Philip Hakala

Graduate Theses, Dissertations, and Problem Reports (ETD)

The influence and relative importance of fine sediment on wild brook trout (Salvelinus fontinalis) population size was assessed. Brook trout production in headwater streams was inversely proportional to substrate permeability in one of two years, suggesting substrate composition influenced production. Results suggest the critical fine sediment size for brook trout in this study, is between 0.063 mm and 1.0 mm. Further, fine sediment (<0.063 mm) should not exceed 0.6--1.0% of spawning substrate, or negative population effects may be incurred. Under normal flow conditions, fine sediment was a principal determinant of juvenile trout abundance relative to other physical and biological factors. Adult trout abundance was principally a function of stream discharge, and is potentially further influenced by fine sediment impacts on juvenile recruitment. Spatially restricted food resources, created by drought-induced low flows in year 2 of the study, are believed to have over-powered mechanisms influencing trout abundance under normal flows.

Diversity Of Ectomycorrhizal Fungi On Two Reclaimed Surface Mines Differing In Soil Properties, Betsy S. Kurnik

Graduate Theses, Dissertations, and Problem Reports (ETD)

I analyzed community structure of ectomycorrhizal fungi on white pine (Pinus strobus) on two reclaimed surface mines in eastern Ohio. One site was acidic and metal-stressed, the other was alkaline. Completely different community composition was found on the two sites by PCR/ITS/RFLP analyses of field collected mycorrhizae. However, Shannon-Wiener index values indicated that the two communities were equally diverse. A population of isolates of one species common to both sites was obtained from trap cultures planted with white pine. The identity of this species as Wilcoxina mikolae was established through DNA sequencing of the ITS region. The W. mikolae populations …

Removal Of Uranium From Aqueous Wastes Using Electrically Charged Carbon Nanofibers, Shannon Lee Stover

Graduate Theses, Dissertations, and Problem Reports (ETD)

The presence of aqueous uranium wastes is a problem in the United States and their treatment/disposal is desirable. Treatment methods have been developed but result in concentration opposed to conversion to a disposable form. This technique involves recovery of uranium as a solid, providing an advantage over other methods. The technique utilizes carbon nanofibers as electrodes which successfully electrosorb uranium ions. Fibers with varying surface characteristics were evaluated in the removal process and all were determined to be equally and extremely effective. Various experimental parameters were evaluated including applied potential, pH, and flow rate. The critical applied potential at which …
