A Measure of Media Bias
(Department of Economics, 2005)
In this paper we estimate ADA (Americans for Democratic Action) scores for major media outlets such as the New York Times, USA Today, Fox News' Special Report, and all three network television news shows. Our estimates ...
Organizational Structure and the Diversification Discount: Evidence from Commercial Banking
(Blackwell, 2008)
This paper provides evidence on organizational structure, geographic diversification, and performance at bank holding companies (BHCs). First, we show that a BHC's member banks benefit from access to the parent organization's ...
Can Entrepreneurship Be Taught?
(2006-02)
Is entrepreneurship an innate ability or an acquired skill? Can entrepreneurial acumen be achieved and enhanced through education and training, or are certain people �born� to be entrepreneurs or to act entrepreneurially? ...
Disseminated chlorellosis in a dog
(American College of Veterinary Pathologists, 2009)
An adult dog with ataxia and a lingual mass, previously diagnosed as protothecosis, was euthanized. At the postmortem examination, the lingual mass, regions of the lungs and hilar lymph nodes, liver, mesenteric and sublumbar ...
Electrochemical properties of carbon nanoparticles entrapped in silica matrix
(Electrochemical Society, 2008)
Carbon-based electrode materials have been widely used for many years for electrochemical charge storage, energy generation, and catalysis. We have developed an electrode material with high specific capacitance by entrapping ...
Adaptive Random Sampling for Traffic Volume Measurement
(Springer Science, 2007-02)
Traffic measurement and monitoring are an important component of network management and traffic engineering. With high-speed Internet backbone links, efficient and effective packet sampling techniques for traffic measurement ...
On the average value of divisor sums in arithmetic progressions
(2005)
We consider very short sums of the divisor function in arithmetic progressions prime to a fixed modulus and show that "on average" these sums are close to the expected value. We also give applications of our result to sums ...
A Kernel-Based Spectral Model for Non-Gaussian Spatio-Temporal Processes
(Statistical Modelling, 2002)
Spatio-temporal processes can often be written as hierarchical state-space processes. In situations with complicated dynamics such as wave propagation, it is difficult to parameterize state transition functions for ...
Multiresolution Models for Nonstationary Spatial Covariance Functions
(Statistical Modelling, 2002)
Many geophysical and environmental problems depend on estimating a spatial process that has nonstationary structure. A nonstationary model is proposed based on the spatial field being a linear combination of a multiresolution ...
Efficient Statistical Mapping of Avian Count Data
(Environmental and Ecological Statistics, 2005)
We develop a spatial modeling framework for count data that is efficient to implement in high-dimensional prediction problems. We consider spectral parameterizations for the spatially varying mean of the Poisson model. The ...
Predicting the Spatial Distribution of Ground Flora on Large Domains Using a Hierarchical Bayesian Model
(Landscape Ecology, 2003)
Accomodation of important sources of uncertainty in ecological models is essential to realistically predicting ecological processes. The purpose of this project is to develop a robust methodology for modeling natural ...
New examples of noncommutative Λ(p) sets
(2003)
In this paper, we introduce a certain combinatorial property Z*(k), which is defined for every integer k ≥ 2, and show that every set E ⊂ Z with the property Z*(k) is necessarily a noncommutative Λ (2k) set. In
particular, ...
Almost All Palindromes Are Composite
(2004)
We study the distribution of palindromic numbers (with respect to a fixed base g ≥ 2) over certain congruence classes, and we derive a nontrivial upper bound for the number of prime palindromes n ≤ x as x → ∞. Our results ...
Irrationality of Power Series for Various Number Theoretic Functions
(2005)
We study formal power series whose coefficients are taken to be a variety of number theoretic functions, such as the Euler, Möbius and divisor functions. We show that these power series are irrational over ℤ [X], and we ...
On the Value Set of n! Modulo a Prime
(2005)
We show that for infinitely many prime numbers p there are at least log log p/ log log log p distinct residue classes modulo p that are not congruent to n! for any integer n.
Values of the Euler Function in Various Sequences
(2005)
Let φ (n) and λ(n) denote the Euler and Carmichael functions, respectively. In this paper, we investigate the equation φ (n)r = λ(n)s, where r ≥ s ≥ 1 are fixed positive integers. We also study those positive integers n, ...
Whittaker-Fourier Coefficients of Metaplectic Eisenstein Series
(2003)
It is shown that the Fourier-Whittaker coefficients of Eisenstein series on the n-fold cover of GL(n) are L-functions, improving prior results of T. Suzuki.
Short Kloosterman Sums for Polynomials over Finite Fields
(2003)
We extend to the setting of polynomials over a finite field certain estimates for short Kloosterman sums originally due to Karatsuba.
Our estimates are then used to establish some uniformity of distribution results in the ...
Character Sums over Integers with Restricted g-ary Digits
(2002)
We establish upper bounds for multiplicative character sums and exponential sums over sets of integers that are described by various
properties of their digits in a fixed base g ≥ 2. Our main tools are the Weil and ...
Matrix inequalities with applications to the theory of iterated kernels
(2003)
For an m × n matrix A with nonnegative real entries, Atkinson, Moran and Watterson proved the inequality s(A)3 ≤ mns(AAtA), where At is the transpose of A, and s(·) is the sum of the entries. We extend this result to finite ...
