Influence Of Varying Intensities Of Natural Area On-Site Interpretation On Attitudes And Knowledge, Michael Hughes Jan 2004

Influence Of Varying Intensities Of Natural Area On-Site Interpretation On Attitudes And Knowledge, Michael Hughes

Theses

Using interpretation as a means of influencing attitudes and knowledge is a core component of natural area management practice. However, this aspect of on-site interpretation is rarely assessed when evaluating natural area management success. This thesis examined the immediate influence of different intensities of on-site interpretation on attitudes and knowledge of visitors to natural areas. Measuring the immediate (short term) influence of a site experience enables clearer links to be made between survey responses and interpretation used at a specific site, something long term surveys are less able to achieve. Two sites from Western Australia (the Tree Top Walk and …

Optical Wave Propagation Through Non-Kolmogorov Atmospheric Turbulence, Paul Anthony Liptack Jan 2004

Optical Wave Propagation Through Non-Kolmogorov Atmospheric Turbulence, Paul Anthony Liptack

Retrospective Theses and Dissertations

The effect of atmospheric turbulence on an optical wave can seriously degrade the reliability of an optical communication link. One atmospheric effect is scintillation, which is caused by index of refraction fluctuations. Several observations of atmospheric turbulence statistics suggest a modest change in the power law behavior of Kolmogorov' s power spectral density model. The corresponding index of refraction fluctuations are assumed to have spatial power spectra that obey power laws that deviate somewhat from the classical - 11/3 power law. The purpose of this study is to develop analytical models for scintillation and other wave propagation statistics based on …

Is The Implicit Association Test A Valid And Valuable Measure Of Implicit Consumer Social Cognition?, Frederic F. Brunel, Brian C. Tietje, Anthony G. Greenwald Jan 2004

Is The Implicit Association Test A Valid And Valuable Measure Of Implicit Consumer Social Cognition?, Frederic F. Brunel, Brian C. Tietje, Anthony G. Greenwald

Marketing

This article discusses the need for more satisfactory implicit measures in consumer psychology and assesses the theoretical foundations, validity, and value of the Implicit Association Test (IAT) as a measure of implicit consumer social cognition. Study 1 demonstrates the IAT’s sensitivity to explicit individual differences in brand attitudes, ownership, and usage frequency, and shows their correlations with IAT-based measures of implicit brand attitudes and brand relationship strength. In Study 2, the contrast between explicit and implicit measures of attitude toward the ad for sportswear advertisements portraying African American (Black) and European American (White) athlete–spokespersons revealed different patterns of responses to …

The Barry Bonds Baseball Case - An Empirical Approach - Is Fleeting Possession Five Tenths Of The Ball?, Peter Adomeit Jan 2004

The Barry Bonds Baseball Case - An Empirical Approach - Is Fleeting Possession Five Tenths Of The Ball?, Peter Adomeit

Faculty Scholarship

Mr. Barry Bonds hit his record seventy-third home run on October 7, 2001. Mr. Alex Popov was smart enough to be in the standing room only area at San Francisco's Pacific Bell Park behind the right field bleachers known as the Arcade, where Mr. Bonds had hit many of his home runs. Mr. Popov was lucky enough to be located almost precisely where the ball was hit, needing only to take one step back. He also had brought a softball glove to the park, as well as a small earbud radio on which he could listen to the play-by-play of …

Labor Market Size And Unemployment Duration: A Theoretical Note, Peter V. Schaeffer, Tesfa Gebremedhin Jan 2004

Labor Market Size And Unemployment Duration: A Theoretical Note, Peter V. Schaeffer, Tesfa Gebremedhin

Regional Research Institute Working Papers

When job prospects are uncertain, labor market size matters even when labor and jobs, respectively, are homogenous. The expected unemployment duration and its standard deviation may then differ systematically with labor market size.

Loop Quantum Gravity And The Cyclic Universe, Martin Bojowald, Roy Maartens, Parampreet Singh Jan 2004

Loop Quantum Gravity And The Cyclic Universe, Martin Bojowald, Roy Maartens, Parampreet Singh

Faculty Publications

Loop quantum gravity introduces strong nonperturbative modifications to the dynamical equations in the semiclassical regime, which are responsible for various novel effects, including resolution of the classical singularity in a Friedman universe. Here we investigate the modifications for the case of a cyclic universe potential, assuming that we can apply the four-dimensional loop quantum formalism within the effective four-dimensional theory of the cyclic scenario. We find that loop quantum effects can dramatically alter the near-collision dynamics of the cyclic scenario. In the kinetic-dominated collapse era, the scalar field is effectively frozen by loop quantum friction, so that the branes approach …

Inflationary Cosmology And Quantization Ambiguities In Semiclassical Loop Quantum Gravity, Martin Bojowald, James E. Lidsey, David J. Mulryne, Parampreet Singh, Reza Tavakol Jan 2004

Inflationary Cosmology And Quantization Ambiguities In Semiclassical Loop Quantum Gravity, Martin Bojowald, James E. Lidsey, David J. Mulryne, Parampreet Singh, Reza Tavakol

Faculty Publications

In loop quantum gravity, modifications to the geometrical density cause a self-interacting scalar field to accelerate away from a minimum of its potential. In principle, this mechanism can generate the conditions that subsequently lead to slow-roll inflation. The consequences for this mechanism of various quantization ambiguities arising within loop quantum cosmology are considered. For the case of a quadratic potential, it is found that some quantization procedures are more likely to generate a phase of slow-roll inflation. In general, however, loop quantum cosmology is robust to ambiguities in the quantization and extends the range of initial conditions for inflation. © …

Excluding Any Graph As A Minor Allows A Low Tree-Width 2-Coloring, Matt Devos, Guoli Ding, Bogdan Oporowski, Daniel P. Sanders, Bruce Reed, Paul Seymour, Dirk Vertigan

Faculty Publications

This article proves the conjecture of Thomas that, for every graph G, there is an integer k such that every graph with no minor isomorphic to G has a 2-coloring of either its vertices or its edges where each color induces a graph of tree-width at most k. Some generalizations are also proved. © 2003 Elsevier Inc. All rights reserved.

Multiplicative Renormalization And Generating Functions Ii, Nobuhiro Asai, Izumi Kubo, Hui Hsiung Kuo Jan 2004

Multiplicative Renormalization And Generating Functions Ii, Nobuhiro Asai, Izumi Kubo, Hui Hsiung Kuo

Faculty Publications

Let μ be a probability measure on the real line with finite moments of all orders. Suppose the linear span of polynomials is dense in L 2(μ). Then there exists a sequence {Pn} n=0∞ orthogonal polynomials with respect to μ such that Pn is a polynomial of degree n with leading coefficient 1 and the equality (x -αn)Pn(x) = Pn+1(x) + wnPn-1(x) holds, where αn and w n are Szegö-Jacobi parameters. In this paper we use the concepts of pre-generating function, multiplicative renormalization, and generating function to derive {Pn,αn,wn} from a given μ Two types of pre-generating functions are studied. …

Seiberg-Witten Vanishing Theorem For S1-Manifolds With Fixed Points, Scott Baldridge Jan 2004

Seiberg-Witten Vanishing Theorem For S1-Manifolds With Fixed Points, Scott Baldridge

Faculty Publications

We show that the Seiberg-Witten invariant is zero for all smooth 4-manifolds with b >1 that admit circle actions having at least one fixed point. We also show that all symplectic 4-manifolds that admit (possibly nonsymplectic) circle actions with fixed points are rational or ruled, and thus admit a symplectic circle action. +

Fork-Decompositions Of Matroids, Rhiannon Hall, James Oxley, Charles Semple, Geoff Whittle Jan 2004

Fork-Decompositions Of Matroids, Rhiannon Hall, James Oxley, Charles Semple, Geoff Whittle

Faculty Publications

One of the central problems in matroid theory is Rota's conjecture that, for all prime powers q, the class of GF(q)-representable matroids has a finite set of excluded minors. This conjecture has been settled for q ≤ 4 but remains open otherwise. Further progress towards this conjecture has been hindered by the fact that, for all q ≥ 5, there are 3-connected GF(q)-representable matroids having arbitrarily many inequivalent GF(q)-representations. This fact refutes a 1988 conjecture of Kahn that 3-connectivity would be strong enough to ensure an absolute bound on the number of such inequivalent representations. This paper introduces fork-connectivity, a …

A Short Proof Of Non-Gf(5)-Representability Of Matroids, Jim Geelen, James Oxley, Dirk Vertigan, Geoff Whittle Jan 2004

A Short Proof Of Non-Gf(5)-Representability Of Matroids, Jim Geelen, James Oxley, Dirk Vertigan, Geoff Whittle

Faculty Publications

Tutte proved that a matroid is binary if and only if it does not contain a U2,4-minor. This provides a short proof for non-GF(2)-representability in that we can verify that a given minor is isomorphic to U2,4 in just a few rank evaluations. Using excluded-minor characterizations, short proofs can also be given of non-representablity over GF(3) and over GF(4). For GF(5), it is not even known whether the set of excluded minors is finite. Nevertheless, we show here that if a matroid is not representable over GF(5), then this can be verified by a short proof. Here a "short proof" …

Homogeneous Multivariate Polynomials With The Half-Plane Property, Young Bin Choe, James G. Oxley, Alan D. Sokal, David G. Wagner Jan 2004

Homogeneous Multivariate Polynomials With The Half-Plane Property, Young Bin Choe, James G. Oxley, Alan D. Sokal, David G. Wagner

Faculty Publications

A polynomial P in n complex variables is said to have the "half-plane property" (or Hurwitz property) if it is nonvanishing whenever all the variables lie in the open right half-plane. Such polynomials arise in combinatorics, reliability theory, electrical circuit theory and statistical mechanics. A particularly important case is when the polynomial is homogeneous and multiaffine: then it is the (weighted) generating polynomial of an r-uniform set system. We prove that the support (set of nonzero coefficients) of a homogeneous multiaffine polynomial with the half-plane property is necessarily the set of bases of a matroid. Conversely, we ask: For which …

Bounded-From-Below Solutions Of The Hamilton-Jacobi Equation For Optimal Control Problems With Exit Times: Vanishing Lagrangians, Eikonal Equations, And Shape-From-Shading, Michael Malisoff Jan 2004

Bounded-From-Below Solutions Of The Hamilton-Jacobi Equation For Optimal Control Problems With Exit Times: Vanishing Lagrangians, Eikonal Equations, And Shape-From-Shading, Michael Malisoff

Faculty Publications

We study the Hamilton-Jacobi equation for undiscounted exit time control problems with general nonnegative Lagrangians using the dynamic programming approach. We prove theorems characterizing the value function as the unique bounded-from-below viscosity solution of the Hamilton-Jacobi equation that is null on the target. The result applies to problems with the property that all trajectories satisfying a certain integral condition must stay in a bounded set. We allow problems for which the Lagrangian is not uniformly bounded below by positive constants, in which the hypotheses of the known uniqueness results for Hamilton-Jacobi equations are not satisfied. We apply our theorems to …
