Paretian Intergenerational Discounting, David A. Weisbach, Dexter Samida Jan 2007

Paretian Intergenerational Discounting, David A. Weisbach, Dexter Samida

Articles

This paper argues that discounting costs and benefits of projects for the opportunity costs of capital Pareto dominates decision criteria that do not discount. It considers and rejects several objections to the Pareto dominance argument, including the problem of making compensating transfers for the costs and benefits of projects and whether taking opportunity costs into account is different than discounting. It also argues that discounting future costs and benefits of projects does not undervalue future generations.

On Wal-Mart: Doing Good By Doing Nothing, Richard A. Epstein Jan 2007

On Wal-Mart: Doing Good By Doing Nothing, Richard A. Epstein

Articles

The major success of Wal-Mart has brought forth an unprecedented amount of criticism of the firm and its business practices. In this Article I subject Wal-Mart's critics to the same scrutiny that they bring to the firm itself, and conclude that virtually all of their charges are overblown and misdirected. In emphasizing the supposed dislocations that Wal-Mart's has had on the settled expectations of certain communities, the critics fail to take into account the positive benefits that the firm supplies its customers in the form of quality goods at low prices and the positive spillovers they provide by revitalizing poor …

On The Most Wanted Folkman Graph, Stanislaw Radziszowski, Xu Xiaodong Jan 2007

On The Most Wanted Folkman Graph, Stanislaw Radziszowski, Xu Xiaodong

Articles

We discuss a branch of Ramsey theory concerning edge Folkman numbers. Fe(3; 3; 4) involves the smallest parameters for which the problem is open, posing the question \What is the smallest order N of a K4-free graph, for which any 2-coloring of its edges must contain at least one monochromatic triangle?" This is equivalent to finding the order N of the smallest K4-free graph which is not a union of two triangle-free graphs. It is known that 16 is less than or equal to N (an easy bound), and it is known through a probabilistic proof by Spencer that N …


Silver Doped Titanium Dioxide Nanomaterials For Enhanced Visible Light Photocatalysis, Michael Seery, Reena George, Suresh Pillai, Patrick Floris Jan 2007

Silver Doped Titanium Dioxide Nanomaterials For Enhanced Visible Light Photocatalysis, Michael Seery, Reena George, Suresh Pillai, Patrick Floris

Articles

This paper presents a systematic study on two different preparation methods for titanium dioxide with silver. The silver can be incorporated by irradiating the reaction mixture during preparation to reduce silver ion to silver metal or by direct calcination of the sol–gel material to decompose silver nitrate to silver. Of the two methods, we found the latter produces a more effective photocatalytic material (6–50% improvement in catalytic efficiency), which is attributed to the fact that the silver is homogeneously dispersed throughout the material. The efficiency of the materials were examined using a Q-Sun solar simulator (visible light) and in Dublin …


Graph Reconstruction Numbers, Mcmullen Brian, Stanislaw Radziszowski Jan 2007

Graph Reconstruction Numbers, Mcmullen Brian, Stanislaw Radziszowski

Articles

Proposed in 1942, the Graph Reconstruction Conjecture posits that every simple, finite, undirected graph with three or more vertices can be reconstructed up to isomorphism to the original graph, given the multiset of subgraphs produced by deleting each vertex along with its incident edges. Related to this Reconstruction Conjecture, existential reconstruction numbers, 9rn(G), concern the minimum number of vertex-deleted subgraphs required to identify a graph up to isomorphism. We discuss the resulting data from calculating reconstruction numbers for all simple, undirected graphs with up to ten vertices. From this data, we establish the reasons behind all high existential reconstruction numbers …


Due Process Traditionalism, Cass R. Sunstein Jan 2007

Due Process Traditionalism, Cass R. Sunstein

Articles

In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and …

Punitive Damages And Valuing Harm, Alexandra B. Klass Jan 2007

Punitive Damages And Valuing Harm, Alexandra B. Klass

Articles

In 2003, the Supreme Court created a presumption that only single-digit ratios of punitive damages to compensatory damages would satisfy substantive due process limits. The exception to this presumption is when the defendant's misconduct results in only a small amount of compensatory damages or when harm is difficult to value. This Article proposes that while lower courts have properly departed from single-digit ratios where the compensatory damage are small, they have had more difficulty doing so when harm is difficult to value. As a result, lower courts are mechanically applying a single-digit ratio in cases where the Court's current framework …


Creating Failures In The Market For Tax Planning, Phillip A. Curry, Claire Hill, Francesco Parisi Jan 2007

Creating Failures In The Market For Tax Planning, Phillip A. Curry, Claire Hill, Francesco Parisi

Articles

In this paper we consider the role of governments in designing their policy for tax planning strategies. We consider two distinct types of social costs: the cost associated with lost tax revenue, and the cost that arises from taxpayers' search for new methods to reduce their tax burden. Inevitably, reducing one of these costs comes at the expense of increasing the other; the government faces a tradeoff. By recognizing these costs and the tradeoff the government faces, we can better understand current tax policy. Moreover, a wider recognition of the tradeoff described above, and a systematic consideration of how to …


An Analysis Of The Determinants Of Mis Faculty Salary Offers, Thomas Tribunella, M. Pamela Neely, Clyde Eiríkur Hull Jan 2007

An Analysis Of The Determinants Of Mis Faculty Salary Offers, Thomas Tribunella, M. Pamela Neely, Clyde Eiríkur Hull

Articles

Much research has been published related to compensation in academic fields such as finance, accounting and economics; however, little attention has been paid to Management Information Systems (MIS). Conspicuously absent from the literature are in-depth studies of faculty compensation and its relationship to research productivity for MIS faculty. This study examines compensation, rank, and publication data collected from the Association for Information Systems (AIS) 2003-2004, 2004-2005, 2005-2006 MIS Salary Surveys. MIS faculty who were newly employed or changed positions filled out the online survey at the AIS Web site on a self-selected productivity and institutional teaching load are reported as …


A Burkean Perspective On Patent Eligibility, Thomas F. Cotter Jan 2007

A Burkean Perspective On Patent Eligibility, Thomas F. Cotter

Articles

Developments in patent law over the past generation, as exemplified by the Patent Board of Appeals and Interferences' recent decision in Ex parte Lundgren, have all but done away with several venerable principles relating to patent eligibility - among them rules that all patentable inventions must pertain to the technological arts, that they may not read on mental steps, and that patentable processes must effect a physical transformation - in favor of an approach that asks only whether an invention has practical utility and is predictable in its effects. As a result, patentable subject matter now includes both the technological …


Reissner–Nordstrom Expansion, Emil Prodanov, Rossen Ivanov, Vesselin Gueorguiev Jan 2007

Reissner–Nordstrom Expansion, Emil Prodanov, Rossen Ivanov, Vesselin Gueorguiev

Articles

We propose a classical mechanism for the cosmic expansion during the radiation-dominated era, assuming the Universe as a two-component gas. The first component is the ultra-relativistic “standard” fraction described by an equation of state of an ideal quantum gas of massless particles. The second component consist of superheavy charged particles and their interaction with the “standard” fraction drives the expansion. This interaction is described by the Reissner–Nordstr¨om metric purely geometrically — the superheavy charged particles are modeled as zero-dimensional naked singularities which exhibit gravitational repulsion. The radius of a repulsive sphere, surrounding a naked singularity of charge Q, is inversely …


On Cosmall Abelian Groups, Brendan Goldsmith, O. Kolman Jan 2007

On Cosmall Abelian Groups, Brendan Goldsmith, O. Kolman

Articles

It is a well-known homological fact that every Abelian groupGhas the property that Hom(G,−)com-mutes with direct products. Here we investigate the ‘dual’ property: an Abelian groupGis said to be cosmallif Hom(−,G)commutes with direct products. We show that cosmall groups are cotorsion-free and that nogroup of cardinality less than a strongly compact cardinal can be cosmall. In particular, if there is a properclass of strongly compact cardinals, then there are no cosmall group

In particular, if there is a proper class of strongly compact cardinals, then there are no cosmall groups.


Hamiltonian Formulation, Nonintegrability And Local Bifurcations For The Ostrovsky Equation, S. Roy Choudhury, Rossen Ivanov, Yue Liu Jan 2007

Hamiltonian Formulation, Nonintegrability And Local Bifurcations For The Ostrovsky Equation, S. Roy Choudhury, Rossen Ivanov, Yue Liu

Articles

The Ostrovsky equation is a model for gravity waves propagating down a channel under the influence of Coriolis force. This equation is a modification of the famous Korteweg-de Vries equation and is also Hamiltonian. However the Ostrovsky equation is not integrable and in this contribution we prove its nonintegrability. We also study local bifurcations of its solitary waves.

Water Waves And Integrability, Rossen Ivanov Jan 2007

Water Waves And Integrability, Rossen Ivanov

Articles

The Euler’s equations describe the motion of inviscid fluid. In the case of shallow water, when a perturbative asymtotic expansion of the Euler’s equations is taken (to a certain order of smallness of the scale parameters), relations to certain integrable equations emerge. Some recent results concerning the use of integrable equation in modeling the motion of shallow water waves are reviewed in this contribution.


Slow Flow Between Concentric Cones, O. Hall, C. P. Hills, A. D. Gilbert Jan 2007

Slow Flow Between Concentric Cones, O. Hall, C. P. Hills, A. D. Gilbert

Articles

This paper considers the low-Reynolds-number flow of an incompressible fluid contained in the gap between two coaxial cones with coincident apices and bounded by a spherical lid. The two cones and the lid are allowed to rotate independently about their common axis, generating a swirling motion. The swirl induces a secondary, meridional circulation through inertial effects. For specific configurations complex eigenmodes representing an infinite sequence of eddies, analogous to those found in two-dimensional corner flows and some three-dimensional geometries, form a component of this secondary circulation. When the cones rotate these eigenmodes, arising from the geometry, compete with the forced …


Krylov Subspaces From Bilinear Representations Of Nonlinear Systems, Marissa Condon, Rossen Ivanov Jan 2007

Krylov Subspaces From Bilinear Representations Of Nonlinear Systems, Marissa Condon, Rossen Ivanov

Articles

For efficient simulation of state-of-the-art dynamical systems as arise in all aspects of engineering, the development of reduced-order models is of paramount importance. While linear reduction techniques have received considerable study, increasingly nonlinear model reduction is becoming a significant field of interest. From a circuits and systems viewpoint, systems involving micromachined devices or systems involving mixed technologies necessitate the development of reduced-order nonlinear models. From a control systems viewpoint, the design of controllers for nonlinear systems is greatly facilitated by nonlinear model reduction strategies. To this end, the paper proposes two novel model-reduction strategies for nonlinear systems. The first involves …


Generalised Fourier Transform For The Camassa-Holm Hierarchy, Adrian Constantin, Vladimir Gerdjikov, Rossen Ivanov Jan 2007

Generalised Fourier Transform For The Camassa-Holm Hierarchy, Adrian Constantin, Vladimir Gerdjikov, Rossen Ivanov

Articles

The squared eigenfunctions of the spectral problem associated to the Camassa-Holm equation represent a complete basis of functions, which helps to describe the Inverse Scattering Transform for the Camassa-Holm hierarchy as a Generalised Fourier transform. The main result of this work is the derivation of the completeness relation for the squared solutions of the Camassa-Holm spectral problem. We show that all the fundamental properties of the Camassa-Holm equation such as the integrals of motion, the description of the equations of the whole hierarchy and their Hamiltonian structures can be naturally expressed making use of the completeness relation and the recursion …


Spectroscopic Characterisation Of Novel Polycyclic Aromatic Polymers, Luke O'Neill, Patrick Lynch, Mary Mcnamara, Hugh Byrne Jan 2007

Spectroscopic Characterisation Of Novel Polycyclic Aromatic Polymers, Luke O'Neill, Patrick Lynch, Mary Mcnamara, Hugh Byrne

Articles

A series of novel polyphenylenevinylene (PPV) derivative polymers were studied by absorption and photoluminescence spectroscopies. The effect of the sequential introduction of polycyclic aromatic ring substituents into the delocalized backbone was examined with relation to hypsochromatic and bathochromatic shifting. While the replacement of the phenyl units by naphthyl units results in a substantial hypsochromic shift of both the absorption and emission spectra, their subsequent substitution by anthryl units results in a bathochromic shift. The system is modeled according to, and is found to be consistent with, a previous study of donor-acceptor polyenes of varying length. The electronic structure of the …


Vibrational Characterisation And Fluorescence Optimisation Of Polycyclic Polymers, Luke O'Neill, Patrick Lynch, Mary Mcnamara, Hugh Byrne Jan 2007

Vibrational Characterisation And Fluorescence Optimisation Of Polycyclic Polymers, Luke O'Neill, Patrick Lynch, Mary Mcnamara, Hugh Byrne

Articles

A systematic series of polycyclic novel polymers was studied by Raman spectroscopy. The effect of the sequential introduction of polycyclic aromatic ring substituents into the delocalized backbone was examined in relation to the variation of the relative ring breathing and stretching as well as the vinyl stretch frequencies. Replacement of the phenyl units by higher order acene moieties such as naphthyl and anthryl results in a shift of the characteristic stretching frequencies, and analysis of the vinyl stretch leads to the confirmation that higher order acene substitution into the delocalized backbone substantially weakens the vinyl bond. Semiquantitative integrated Raman analysis …
