Economy And 'New Economy' In The United States And Germany, Phillip J. Bryson

Faculty Publications

The expression "New Economy" is used inconsistently. This Article review the driving forces of the US boom of the 1990s, examining the changes introduced in the period and before, focusing on the IT sector and new technologies. The "New Economy" is not just the new sectors, but changes in the overall economy emanating from them. These changes will not evaporate in an economic slowdown. Comparisons of the USA with Germany and Europe illustrate that the "New Economy" will also continue to develop there on the foundations already laid.

Study Of The Effective Transverse Momentum Of Partons In The Proton Using Prompt Photons In Photoproduction At Hera, S. Chekanov, M. Derrick, D. Krakauer, S. Magill, B. Musgrave, A. Pellegrino, J.

The photoproduction of prompt photons, together with an accompanying jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 38.6 pb-1. A study of the effective transverse momentum, (kT), of partons in the proton, as modelled within the framework of the PYTHIA Monte Carlo, gives a value of (kT) = 1.69 ± 0.18 -0.20+0.18 GeV for the γp centre-of-mass energy range 134 < W < 251 GeV. This result is in agreement with the previously observed trend in hadron-hadron scattering for (kT) to rise with interaction energy. © 2001 Elsevier Science B.V.

Parenting Stress In Families With Children With Disabilities, Timothy B. Smith, Matthew N. I. Oliver, Mark S. Innocenti

Faculty Publications

Parenting stress is an important variable to consider in families with children with disabilities. This study evaluated 880 such families, using measures of child and family functioning. Results suggest that factors such as income, time available for interaction with the child, and social support predict parenting stress much better than do aspects of child functioning.

The Uniform Health-Care Decisions Act And Its Progress In The States, David M. English

Faculty Publications

Over the past decade, planning for health care decision making through the making of an advance directive has become a routine part of personal counseling. Public interest in the subject has been fueled by well-publicized cases such as Cruzan v. Director, Missouri Department of Health, 497 U.S. 261 (1990). In response to this interest, most states authorize their citizens to make at least one form of advance directive: all states statutorily authorize powers of attorney for health care, and all but Massachusetts, Michigan and New York authorize living wills. State legislation has been a mixed blessing. Although intended to facilitate …

Interpolating Implicit Surfaces From Scattered Surface Data Using Compactly Supported Radial Basis Functions, Bryan S. Morse, David T. Chen, Penny Rheingans, Kalpathi Subramanian, Terry S. Yoo

Faculty Publications

We describe algebraic methods for creating implicit surfaces using linear combinations of radial basis interpolants to form complex models from scattered surface points. Shapes with arbitrary topology are easily represented without the usual interpolation or aliasing errors arising from discrete sampling. These methods were first applied to implicit surfaces by Savchenko, et al. and later developed independently by Turk and O'Brien as a means of performing shape interpolation. Earlier approaches were limited as a modeling mechanism because of the order of the computational complexity involved. We explore and extend these implicit interpolating methods to make them suitable for systems of …

Most of the studies appeared during the six-month period preceding the compilation of the bibliography (June through December, 2000,for the present bibliography), but some studies that appeared earlier are occasionally included. The listing is selective; we make no attempt to include all research and research-related articles that appeared in the period under review. Comments on the bibliography and suggestions about items for inclusion may be directed to the bibliography editors. We encourage you to send your suggestions to …

Image Reconstruction Using Data-Dependent Triangulation, Thomas W. Sederberg, Xiaohua Yu, Bryan S. Morse

Faculty Publications

Image reconstruction based on data-dependent triangulation with new cost functions and optimization can create higher quality images than traditional bilinear or bicubic spline reconstruction. The article presents a novel method for image reconstruction using a piecewise linear intensity surface whose elements don't generally align with the coordinate axes. This method is based on the technique of data-dependent triangulation (DDT) that N. Dyn et al. (1990) introduced and has proven capable of producing more pleasing reconstructions than axis-aligned methods.

Effective Bandwidth For Traffic Engineering, Mark J. Clement, Rob Kunz, Seth Nielson, Quinn O. Snell

Faculty Publications

In today’s Internet, demand is increasing for guarantees of speed and efficiency. Current routers are very limited in the type and quantity of observed data they can provide, making it difficult for providers to maximize utilization without the risk of degraded throughput. This research uses statistical data currents provided by router vendors to estimate the impact of changes in network configuration on the probability of link overflow. This allows service providers to calculate in advance, the effect of grooming on a network, eliminating the conservative trial-and-error approach normally used. These predictions are made using Large Deviation Theory, which focuses on …

Charge Effects On Gravitational Wave Detectors, R. F. O'Connell

Faculty Publications

We show that the mean-square displacement of a charged oscillator due to the zero point oscillations of the radiation field is unique in the sense that it is very sensitive to the value of the bare mass of the charge. Thus, a controlled experiment using gravitational wave detectors could lead to a determination of the electron bare mass and shed some light on quantum electrodynamic theory. We also speculate that the irregular signals of non-gravitational origin often observed in gravitational wave bar detectors could be caused by stray charges and that such charges could also adversely affect LIGO and other …

What Determines The Emission Peak Energy Of The Blue Luminescence In Highly Mg-Doped P-Gan?, John S. Colton, P. Y. Yu

Faculty Publications

We report a study of the 2.8 eV blue luminescence (BL) in heaviliy Mg-doped p-GaN via resonant excitation with a tunable blue dye laser. The dependence of the BL on the excitation photon energy (Eex) is unlike that of the yellow luminescence found in n-type GaN. An Urbach-type band tail, with Urbach parameter of 33 meV is observed in the vicinity of the BL energy. We propose that the peak energy of the BL marks the transition from localized states to delocalized states within this band tail.

On The Meromorphic Extension Of The Spherical Functions On Noncompactly Causal Symmetric Spaces, G. Ólafsson, A. Pasquale

Faculty Publications

We determine integral formulas for the meromorphic extension in the λ-parameter of the spherical functions φλ on a noncompactly causal symmetric space. The main tool is Bernstein's theorem on the meromorphic extension of complex powers of polynomials. The regularity properties of φλ are deduced. In particular, the possible λ-poles of φλ are located among the translates of the zeros of the Bernstein polynomial. The translation parameter depends only on the structure of the symmetric space. The expression of the Bernstein polynomial is conjectured. The relation between the Bernstein polynomial and the product formula of the cΩ-function is analyzed. The conjecture …

Seasonal Variation Of The North Atlantic Current, Max I. Yaremchuk, Dmitri A. Nechaev, Keith R. Thompson

Faculty Publications

The seasonal circulation of the upper 1000 m of the North Atlantic between 40 degrees -55 degreesN and 20 degrees -40 degreesW is calculated using the traditional dynamic method and a circulation model with a density field that evolves with the flow. The model is of finite difference form and is based on dynamics that describe the nonlinear evolution of the ocean at low Rossby number. The model is controlled by initial and boundary conditions that include air-sea buoyancy and momentum fluxes. The model is run in two ways: with controls specified directly from observations and with controls inferred by …

Blowup In A Mass-Conserving Convection-Diffusion Equation With Superquadratic Nonlinearity, Todd L. Fisher, Christopher P. Grant

Faculty Publications

A nonlinear convection-diffusion equation with boundary conditions that conserve the spatial integral of the solution is considered. Previous results on nite-time blowup of solutions and on decay of solutions to the corresponding Cauchy problem were based on the assumption that the nonlinearity obeyed a power law. In this paper, it is shown that assumptions on the growth rate of the nonlinearity, which take the form of weak superquadraticity and strong superlinearity criteria, are suffcient to imply that a large class of nonnegative solutions blow up in nite time.

Of Manatees, Mangroves, And The Mississippi River: Is There An Estuarine Signature For The Gulf Of Mexico?, R. Eugene Turner

Faculty Publications

Important parameters of estuarine variability include morphology, flushing times, nutrient loading rates, and wetland: water ratios. This variability both reflects and disguises underlying relationships between the physics and biology of estuaries, which this comparative analysis seeks to reveal, using the Gulf of Mexico (GOM) estuaries as a starting point. A question used to focus this analysis is: are the GOM estuaries unique? The GOM receives the Mississippi River, a uniquely large, world-class river, which dominates the freshwater and nutrient inflows to the GOM continental shelf, whose margins include 35 major estuarine systems. These GOM estuaries have 28% and 41% of …

Sr3Znpto6 And Sr3Cdpto6, Mark D. Smith, Hans Conrad Zur Loye

Faculty Publications

The flux synthesis of single crystals of the isostructural compounds tristrontium zinc platinum hexaoxide, Sr₃ZnPtO₆, and tristrontium cadmium platinum hexaoxide, Sr₃CdPtO₆, is reported. The compounds adopt the pseudo-one-dimensional rhombohedral K₄CdCl₆ structure type, and feature chains of face-shared distorted ZnO₆ or CdO₆ trigonal prisms and PtO₆ octahedra, surrounded by columns of Sr²⁺ ions. All transition metals are located on the threefold axis of symmetry, while the Sr²⁺ cations lie on twofold axes.

Formula: Sr₃ZnPtO₆ and Sr₃CdPtO₆

Social Influence On Paranormal Beliefs, Barry N. Markovsky, Shane R. Thye

Faculty Publications

In spite of strong public expressions of skepticism from the scientific community, polls show that more than nine out of ten American adults profess belief in paranormal phenomena. Some scientists view this as a social problem, directing much blame (but little research) at a variety of sources including lack of critical thinking skills, fads, need for transcendent experiences, failure of the educational system, and cultural cycles. Social impact theory provides an alternative focus: it views paranormal beliefs as a natural consequence of social influence processes in interpersonal settings. In this study, subjects in a laboratory experiment were informed that some …

Court Administration As A Tool For Judicial Reform, Christie S. Warren

Faculty Publications

This paper focuses on court administration as a component of judicial branch reform in the United States and other countries.

Over the past fifty years, state and federal court systems in the United States have undergone a process of significant change. At the beginning of the twentieth century, courts were largely dependent upon the executive branch of government for administrative support and were for the most part externally dominated, disorganized, and poorly managed. By the end of the century, they had undergone a process of administrative innovation and improvement that changed the way they were managed. In other countries, judicial …

Anomalous Nmr Spin-Lattice Relaxation In Srb6 And Ca1-Xlaxb6, J. L. Gavilano, Sh Mushkolaj, D. Rau, H. R. Ott, A. Bianchi, D. P. Young, Z. Fisk

Faculty Publications

We report the results of 11B nuclear magnetic resonance (NMR) measurements of SrB6 and Ca0.995La0.005B6 below room temperature. Although the electrical resistivities of these two materials differ substantially, their 11B-NMR responses exhibit some strikingly common features. Both materials exhibit ferromagnetic order, but their 11B-NMR spectra reveal very small hyperfine fields at the boron sites. The spin-lattice relaxation T-11 varies considerably with external field but changes with temperature only below a few K. We discuss these unusual results by considering various different scenarios for the electronic structure of these materials. © 2001 The American Physical Society.

The Field Equation From Newton's Law Of Motion And The Absence Of Magnetic Monopole, Parampreet Singh, Naresh Dadhich

Faculty Publications

By requiring the linear differential operator in Newton's law of motion to be self adjoint, we obtain the field equation for the linear theory, which is the classical electrodynamics. In the process, we are also led to a fundamental universal chiral relation between electric and magnetic monopoles which implies that the two are related. Thus there could just exist only one kind of charge which is conventionally called electric.

A Note On Doubles Of Groups, Nadia Benakli, Oliver T. Dasbach, Yair Glasner, Brian Mangum

Faculty Publications

Recently, Rips produced an example of a double of two free groups which has unsolvable generalized word problem. In this paper, we show that Rips's example fits into a large class of doubles of groups, each member of which contains F2×F2 and therefore has unsolvable generalized word problem and is incoherent. © 2001 Elsevier Science B.V.

Highly Doped Thin-Channel Gan-Metal-Semiconductor Field-Effect Transistors, R. Gaska, M. S. Shur, X. Hu, J. W. Yang, A. Tarakji, Grigory Simin, A. Khan, J. Deng, T. Werner, S. Rumyantsev, N. Pala

Faculty Publications

We report on the influence of the channel doping on dc, high frequency, and noise performance of GaN metal–semiconductor field-effect transistors (MESFETs) grown on sapphire substrates. The devices with the channel thicknesses from 50 to 70 nm and doping levels up to 1.5×10¹⁸ cm⁻³ were investigated. An increase in the channel doping results in the improved dc characteristics, higher cutoff, and maximum oscillation frequencies, and reduced low frequency and microwave noise. The obtained results demonstrate that the dc and microwave performance characteristics of short-channel GaN MESFETs may be comparable to those for conventional AlGaN/GaN heterostructure FETs.

Assessment Of Contemporary Arctic River Runoff Based On Observational Discharge Records, Richard B. Lammers, Alexander I. Shiklomanov, Charles J. Vorosmarty, Balazs M. Fekete, Bruce J. Peterson

Faculty Publications

We describe the contemporary hydrography of the pan‐Arctic land area draining into the Arctic Ocean, northern Bering Sea, and Hudson Bay on the basis of observational records of river discharge and computed runoff. The Regional Arctic Hydrographic Network data set, R‐ArcticNET, is presented, which is based on 3754 recording stations drawn from Russian, Canadian, European, and U.S. archives. R‐ArcticNET represents the single largest data compendium of observed discharge in the Arctic. Approximately 73% of the nonglaciated area of the pan‐Arctic is monitored by at least one river discharge gage giving a mean gage density of 168 gages per 106 km2. …

Image Reconstruction And Enhanced Resolution Imaging From Irregular Samples, David G. Long, David S. Early

Faculty Publications

While high resolution, regularly gridded observations are generally preferred in remote sensing, actual observations are often not evenly sampled and have lower-than-desired resolution. Hence, there is an interest in resolution enhancement and image reconstruction. This paper discusses a general theory and techniques for image reconstruction and creating enhanced resolution images from irregularly sampled data. Using irregular sampling theory, we consider how the frequency content in aperture function-attenuated sidelobes can be recovered from oversampled data using reconstruction techniques, thus taking advantage of the high frequency content of measurements made with nonideal aperture filters. We show that with minor modification, the algebraic …

Language Acquisition In Children With Autism, Tina Taylor

Faculty Publications

By definition, children with autism have deficits in communication. Often, when parents notice that something is "different" about their child, it is that he does not acquire language at the same rate as his peers, that the child uses what language he has in an idiosyncratic fashion (e.g., repeating phrases from videos, using pronouns incorrectly), or that the child appears to understand only that language which might be reinforcing to him (e.g., not responding to "Look at Mommy," but responding to "Do you want a cookie?)" When these "red flags" are apparent, parents should beware of misguided advice such as …

Lexical Failure And Gesture In Second Language Development, Gale Stam

Faculty Publications

Second language acquisition can be defined as the acquisition of another language after the age of three or four (Klein, 1986). It involves the learning and mastery of the morphology, syntax, phonology, and lexicon of the new language. The process by which learners acquire a second language is complex, gradual, nonlinear, and dynamic (Larsen- Freeman, 1991). Depending on their stage of second language development, learners may have difficulty retrieving words, or they may not know words at all and exhibit lexical failure.

Butterworth and Hadar (1989, 1997) have proposed that iconic gestures arise when speakers have a lexical retrieval problem …

Opening The Front Door: Designing A Usable Library Web Site, Andrew Keck

Faculty Publications

The library website is a significant access point to a library’s collections, resources, and services. A website can and should provide information about the library in a way that can be efficiently navigated and used by all library patrons. The usability of a library website can be improved through changes in organization and design informed by the experiences of real users. User expectations should be primary in determining the content, purpose, organization, and design of the site.
