#### 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? ...

#### Analysis of point-to-point packet delay in an operational network, Computer Networks

(Elesevier, 2007-09-12)

In this paper, we perform a detailed analysis of point-to-point packet delay in an operational tier-1 network. The point-to-point delay is the time experienced by a packet from an ingress to an egress point in an ISP, and ...

#### 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 ...

#### QoS and channel aware packet bundling for VoIP traffic in cellular networks

(IEEE, 2009-09-16)

We study the problem of multiple packet bundling to improve spectral efficiency in cellular networks. The packet size of real-time data, such as VoIP, is often very small. However, the use of time division multiplexing ...

#### Inequalities of correlation type for symmetric stable random vectors

(2011)

We point out a certain class of functions f and g for which random variables f(X1,...,Xm) and g(Xm+1,...,Xk) are non-negatively correlated for any symmetric jointly stable random variables Xi. We also show another result ...

#### Comparison of sums of independent identically distributed random variables

(2011)

Let Sk be the k-th partial sum of Banach space valued independent identically distributed random variables. In this paper, we compare the tail distribution of ∥Sk∥ with that of ∥Sj∥, and deduce some tail distribution maximal ...

#### Hahn's embedding theorem for orders and harmonic analysis on groups with ordered duals

(2011)

Let G be a locally compact abelian group whose dual group Γ contains a Haar measurable order P. Using the order P we define the conjugate function operator on Lp(G), 1 ≤ p < ∞, as was done by Helson. We will show how to ...

#### Orlicz-Lorentz Spaces

(2011)

The purpose of this article is to summerize some recent results of the author about Orlicz-Lorentz spaces - function spaces that provide a common generalization of Orlicz spaces and Lorentz spaces.

#### Some conjectures about integral means of ∂f and ∂¯f

(2011)

We discuss some conjectural inequalities concerning a problem from the calculus of variations, namely that rank 1 convex functions are quasi-convex. An affirmative answer would also give the best constants for the ...

#### 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 ...

#### 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 ...

#### 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 ...

#### On singular integral and martingale transforms

(2011)

Linear equivalences of norms of vector-valued singular integral operators and vector-valued martingale transforms are studied. In particular, it is shown that the UMD(p)-constant of a Banach space X equals the norm of the ...

#### Decoupling inequalities for the tail probabilities of multivariate u-statistics

(2011)

In this paper we present a decoupling inequality that shows that multivariate U-statistics can be studied as sums of (conditionally) independent random variables. This result has important implications in several areas of ...

#### Hierarchical Bayesian Approach to Boundary Value Problems with Stochastic Boundary Conditions

(American Meteorological Society, 2003)

Boundary value problems are ubiquitous in the atmospheric and ocean sciences. Typical settings include bounded, partially bounded, global and limited area domains, discretized for applications of numerical models of
the ...

#### Hierarchical Bayesian Models for Predicting The Spread of Ecological Processes

(Ecological Society of America, 2003)

There is increasing interest in predicting ecological processes. Methods to accomplish such predictions must account for uncertainties in observation, sampling,
models, and parameters. Statistical methods for spatio-temporal ...

#### The spectrum of the kinematic dynamo operator for an ideally conducting fluid

(2011)

The spectrum of the kinematic dynamo operator for an ideally conducting fluid and the spectrum of the corresponding group acting in
the space of continuous divergence free vector fields on a compact Riemannian manifold ...

#### Contraction and decoupling inequalities for multilinear forms and u-statistics

(2011)

We prove decoupling inequalities for random polynomials in independent random variables with coefficients in vector space. We use various means of comparison, including rearrangement invariant norms (e.g., Orlicz and Lorentz ...

#### Finite time blow up for a Navier-Stokes like equation

(2011)

We consider an equation similar to the Navier-Stokes equation. We show that there is initial data that exists in every Triebel-Lizorkin or Besov space (and hence in every Lebesgue and Sobolev space), such that after a ...
