Hydrocarbon Ions In The Ionosphere Of Titan, Jane L. Fox, Roger V. Yelle

Physics Faculty Publications

We have constructed a new model of the ionosphere of Titan that includes 67 species and 626 reactions. Although N₂⁺ is the major ion produced over most of the ionosphere, the ionization flows to ions whose parent neutrals have lower ionization potentials and to ions formed from species with large proton affinities. In contrast to other models, which have predicted that HCNH⁺ should be the major ion, our calculations suggest that the major ions at and below the ion peak are hydrocarbon ions, and H, C, and N-containing ions. Our predicted peak electron density for a solar …

Large Deviations And The Distribution Of Price Changes, Laurent Calvet, Adlai Fisher, Benoit Mandelbrot

Cowles Foundation Discussion Papers

The Multifractal Model of Asset Returns (“MMAR,” see Mandelbrot, Fisher, and Calvet, 1997) proposes a class of multifractal processes for the modelling of financial returns. In that paper, multifractal processes are defined by a scaling law for moments of the processes’ increments over finite time intervals. In the present paper, we discuss the local behavior of multifractal processes. We employ local Hölder exponents, a fundamental concept in real analysis that describes the local scaling properties of a realized path at any point in time. In contrast with the standard models of continuous time finance, multifractal processes contain a multiplicity of …

Multifractality Of Deutschemark/Us Dollar Exchange Rates, Adlai Fisher, Laurent Calvet, Benoit Mandelbrot

Cowles Foundation Discussion Papers

This paper presents the first empirical investigation of the Multifractal Model of Asset Returns (“MMAR”). The MMAR, developed in Mandelbrot, Fisher, and Calvet (1997), is an alternative to ARCH-type representations for modelling temporal heterogeneity in financial returns. Typically, researchers introduce temporal heterogeneity through time-varying conditional second moments in a discrete time framework. Multifractality introduces a new source of heterogeneity through time-varying local regularity in the price path. The concept of local Hölder exponent describes local regularity. Multifractal processes bridge the gap between locally Gaussian (Itô) diffusions and jump-diffusions by allowing a multiplicity of Hölder exponents. This paper investigates multifractality in …

New Learning Paradigms For Catholic Education, Angela Ann Zukowski

Journal of Catholic Education

A paradigm shift is needed in Catholic education for the 21st century. The new paradigm needs to communicate that the purpose of Catholic education is not to transfer knowledge but to create environments and experiences that bring students to discover for themselves, to make students members of communities of learners that make discoveries and solve problems. The New Frontiers for Catholic Schools project supports educators in making technology a vital part of the future of Catholic education.

Ion Acceleration And Anomalous Transport In The Near Wake Of A Plasma Limiter, D. P. Sheehan, J. Bowles, R. Mcwilliams

Physics and Biophysics: Faculty Scholarship

Ion acceleration and anomalous transport were studied experimentally in the near wake region of an electrically floating disk limiter immersed in two different types of collisionless, supersonically flowing, magnetized plasmas: the first initially quiescent, the second initially turbulent. Ion densities and velocity distributions were obtained using a nonperturbing laser induced fluorescence diagnostic. Large-amplitude, low-frequency turbulence was observed at the obstacle edge and in the wake. Rapid ion and electron configuration space transport and ion velocity space transport were observed. Configuration space and velocity space transport were similar for both quiescent and turbulent plasma-obstacle systems, suggesting that plasma-obstacle effects outweigh the …

Effect Of Bmp Implementation On Storm Flow Quality Of Two Northwestern Arkansas Streams, Dwayne R. Edwards, Tommy C. Daniel, H. Don Scott, Phillip A. Moore Jr., John F. Murdoch, Paul F. Vendrell

Biosystems and Agricultural Engineering Faculty Publications

The effectiveness of management practices in improving quality of runoff from agricultural land areas has been reported based primarily on results from plot- and field-scale studies. There is limited information available on watershed scales, particularly when the dominant agricultural land use is pasture. The objective of this study was to determine whether a program of Best Management Practice (BMP) implementation in the Lincoln Lake watershed of northwestern Arkansas was effective in reducing storm stream flow concentrations and mass transport of nitrate nitrogen (NO₃-N), ammonia nitrogen (NH₃-N), total Kjeldahl nitrogen (TKN), ortho-phosphorus (PO₄-P), total phosphorus …

Magnetic And Structural Properties Of Sm2Fe10Co7/MXCY Thin Films, I.A. Al-Omari, N. J. Cunningham, David J. Sellmyer

David Sellmyer Publications

The structural and magnetic properties of Sm₂Fe₁₀Co₇/M_xC_y (M=A1 and Si; x≥0 and y≥0) multilayer films with Ta underlayers and overlayers before and after annealing at 700 °C for 5-12 min have been fabricated and studied. Structural studies show evidence of layer diffusion upon annealing. X-ray diffraction shows that the samples after annealing consist of a soft phase, α -Fe, and a hard phase with the 2-17-type structure. The samples studied have in-plane anisotropy with single hysteresis loops indicating that the two phases are strongly exchange coupled. After annealing, the coercivity of …

A Comparison Of Movements And Burrow Usage Between Indigenous And Relocated Gopher Tortoises (Gopherus Polyphemus) In A Fall Line Sandhills Community, Dorinda Morpeth

Theses and Dissertations

The movements and burrow use of twenty (ten relocated and ten indigenous to the relocation site) adult gopher tortoises {Gopherus polyphemus) were followed during the late spring, summer and early autumn in Talbot County, Georgia. The objectives of this study were to determine whether relocated gopher tortoises developed fidelity to a relocation site, and whether indigenous tortoises reacted adversely to relocated tortoises released in their proximity. Ten tortoises in the right-of-way of a highway construction project were captured, fitted with transmitters, and relocated to a 336 hectare tract of land, 3.2 km east of Geneva, Talbot, County, Georgia. Concurrently, ten …

Water Transport And The Distribution Of Aquaporin-1 In Pulmonary Air Spaces, Richard M. Effros, C. Darin, Elizabeth R. Jacobs, R. A. Rogers, Gary S. Krenz, E. E. Schneeberger

Biomedical Engineering Faculty Research and Publications

Recent evidence suggests that water transport between the pulmonary vasculature and air spaces can be inhibited by HgCl₂, an agent that inhibits water channels (aquaporin-1 and -5) of cell membranes. In the present study of isolated rat lungs, clearances of labeled (³HOH) and unlabeled water were compared after instillation of hypotonic or hypertonic solutions into the air spaces or injection of a hypotonic bolus into the pulmonary artery. The clearance of ³HOH between the air spaces and perfusate after intratracheal instillation and from the vasculature to the tissues after pulmonary arterial injections was invariably greater …

Theory And Generation X, Gary S. Marshall

Public Administration Faculty Publications

This special issues section of JPAE provides an opportunity to address the experience of the new generation of MPA students who are often labeled the X Generation. The term Generation X was coined by Coupland (1991); "X" in this case refers to the mathematical symbol for indeterminacy or the unknown. The argument implicit in the moniker is that, while all previous generations had some point of reference that provided them with a social anchor, the current generation does not have such an anchor through which to interpret their social experience. As a result, they are often depicted as "slackers" with …

Is Chapter 11 Too Favorable To Debtors? Evidence From Abroad, Theodore Eisenberg, Stefan Sundgren

Cornell Law Faculty Publications

Chapter 11 is widely believed to be among the industrialized world's most debtor-oriented reorganization laws. Critics assert that Chapter 11 is too easily available and that it allows debtors too much control by, inter alia, not requiring appointment of a trustee. One criticism of Chapter 11, low returns to unsecured creditors, resonates with an important theme of this Symposium, the Bebchuk-Fried proposal to reduce secured creditor priority in insolvency proceedings. The Chapter 11 criticisms and the Bebchuk-Fried proposal raise the question whether less easy access to Chapter 11, reduced debtor control, diminished secured creditor priority, or other changes could reduce …

Reorientations Of Flexible Spacecraft Using Momentum Exchange Devices, Kevin A. Ford

Theses and Dissertations

We study rest-to-rest reorientations of flexible spacecraft using momentum exchange devices. A new and concise form of the equations of motion for a rigid body containing a cluster of gimbaled momentum wheels is developed using the Euler-Newton approach. Special restrictions of the gimbaled momentum wheel equations yield equations of motion for the momentum wheel cluster and the control moment gyroscope cluster. A mathematical model of a free spacecraft with Euler-Bernoulli appendages is developed. Using the assumed modes method, a complete set of equations is developed which describes the dynamics of a spacecraft with flexible appendages and gimbaled momentum wheels. Special …

Measurement Issues In Poverty, A. Englama, A. Bamidele

Economic and Financial Review

The paper defines poverty as certain disabilities such as the inability to participate with dignity in society. It also demonstrates that in measuring poverty, emphasis should not be mainly on income or consumption, hut that cognizance should be taken of social, economic and basic infrastructures as well as environmental factors. The paper farther mentions some inherent problems in measuring poverty such as conceptual and data problems. Once these problems are overcome, a simple head count could provide an insight into poverty measurement. J11e depth and severity of poverty can be determined by the P-Index which captures the number of the …

First Graders Solving Problems, Mary H. Burke

Critical and Creative Thinking Capstones Collection

First graders become good problem solvers when given the opportunity to practice problem solving skills. It is necessary for such practice to take place in a risk-free environment that treats errors as valuable learning experiences rather than something to always avoid. This thesis integrates academic subject matter, school life interactions, and out of school experiences into the first graders' development of critical thinking skills and strategies necessary for them to become good problem solvers. The thesis explains in several different academic subject areas the implementation of critical and creative thinking pedagogy essential for the development of a sound foundation for …

On The Product Of Two Generalized Derivations, Mohamed Barraa, Steen Pedersen

Mathematics and Statistics Faculty Publications

Two elements A and B in a ring R determine a generalized derivation delta_A,B on R by setting δ_A,B(X) = AX - XA for any X in R. We characterize when the product δ_C,Dδ_A,B is a generalized derivation in the cases when the ring R is the algebra of all bounded operators on a Banach space epsilon, and when R is a C*-algebra U. We use the se characterizations to compute the commutant of the range of δ_A,B.

Arguing that guidelines for identifying carcinogens now lack a philosophically rigorous framework, the authors present an alternative that draws clear attention to the process of reasoning towards judgments of carcinogenicity.

On The Suprema Distribution Of Gaussian Processes With Stationary Increment And Drift, Jinwoo Choe, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In this report we study the suprema distribution of a class of Gaussian processes having stationary increments and negative drift using key results from ~Txtrerne Value Theory. We focus on deriving an asymptotic upper bound to the tail of the suprema distribution of such processes. Our bound is valid for both discrete- and continuous-time processes. VVe discuss the importance of the bound, its applicability to queueing problems, and show numerical examples to illustrate its performance.

Irrational Expectations, Lynn A. Stout

Cornell Law Faculty Publications

Rational expectations models have become a staple of economic theory and the basis for a Nobel Prize. This article argues that rational expectations analysis suffers from potentially fatal flaws that seriously undermine its value in understanding many market phenomena. Using the example of financial markets, the article illustrates how the rational expectations approach has worked to obscure, rather than to illuminate, our understanding of speculation and speculative markets. This misguidance raises problems for law and policy.
