Carbon Capture And Sequestration: Identifying And Managing Risks, Alexandra B. Klass, Elizabeth J. Wilson Jan 2009

Carbon Capture And Sequestration: Identifying And Managing Risks, Alexandra B. Klass, Elizabeth J. Wilson

Articles

Carbon capture and geologic sequestration (CCS) technology promises to provide deep emissions cuts, particularly from coal power generation, but deploying CCS creates risks of its own. This article first considers the risks associated with CCS, which involves capturing CO{sub 2} emissions from industrial sources and power plants, transporting the CO{sub 2} by pipeline, and injecting it underground for permanent sequestration. The article then suggests ways in which these risks can be minimized and managed and considers more broadly when or if CCS should be deployed or whether its use should be limited or rejected in favor of other solutions.


Staying Alive: Public Interest Law In Contemporary Latin America, Stephen Meili Jan 2009

Staying Alive: Public Interest Law In Contemporary Latin America, Stephen Meili

Articles

This paper explores the current state of public interest lawyering in three Latin American countries: Argentina, Brazil and Chile. Based on a series of open-ended interviews with lawyers, judges and social movement activists, it compares public interest lawyering in these countries now with how it was practiced when the author interviewed some of the same individuals in the early to mid 1990s. Its analysis is set within the context of important geopolitical and socio-legal phenomena: the current global economic crisis and the judicialization of politics and constitutionalization of rights that has swept across the region over the past two decades. …


Child Protection -- What Ought To Be, Donald N. Duquette Jan 2009

Child Protection -- What Ought To Be, Donald N. Duquette

Articles

America's child protection system should not only protect our children, it should protect our liberty. Several recent cases, and perhaps others in your jurisdiction, highlight a general tension in America's child protection system between child protection and family integrity.

Building The Bottom Up From The Top Down, A. Michael Froomkin Jan 2009

Building The Bottom Up From The Top Down, A. Michael Froomkin

Articles

"Bottom up" governance. "Self-organization." These are among the most talismanic virtue-words of modern political discourse. Yet the reality is that in politics, "self-organization" is rare, being hard to initiate and even harder to sustain. As Oscar Wilde once complained about socialism, it "requires too many evenings." Governance as we tend to know it depends primarily on hierarchical institutions, or on close coordination within small groups. True partnerships, conversations among engaged equals, do not seem to scale. Indeed, whether one believes the fundamental problem to be something about the economics of group formation, the iron law of oligarchy, or something in …

Alternative Approach For Teaching Multibody Dynamics, George Sutherland Jan 2009

Alternative Approach For Teaching Multibody Dynamics, George Sutherland

Articles

The paper presents an alternative method, the Implicit Constraint Approach (ICA), for developing the equations of motion to describe a system of connected bodies typified by mechanisms and robotic devices. By its simplicity of description and implementation compared to conventional methods, the ICA engages students more in the physics (rather than the mathematics) of the system under study. The ICA enables the direct formation of all needed equations by using only the dynamic equilibrium conditions (in the Newton or Lagrange form). Unlike current approaches, no auxiliary algebraic constraint equations are required. Thus the descriptive equations are ordinary differential equation (ODEs) …


From Banners To Youtube: Using The Rear-View Mirror To Look At The Future Of Internet Advertising, Susan Barnes, Neil Hair Jan 2009

From Banners To Youtube: Using The Rear-View Mirror To Look At The Future Of Internet Advertising, Susan Barnes, Neil Hair

Articles

In twelve short years, Internet advertising has evolved from banners to experiential promotions. In the beginning advertisers viewed the Internet in similar ways as they considered traditional media (television, newspaper, magazines). The idea of using a new medium like an older one, was described by McLuhan's concept of the rear view mirror. This article describes the history of Internet advertising from 1994 to 2006 by looking back to understand the future direction of Internet advertising.

Is Visual Selective Attention In Deaf Individuals Enhanced Or Deficient? The Case Of Useful Field Of View, Matthew Dye, Peter Hauser, Daphne Bavelier Jan 2009

Is Visual Selective Attention In Deaf Individuals Enhanced Or Deficient? The Case Of Useful Field Of View, Matthew Dye, Peter Hauser, Daphne Bavelier

Articles

Background: Early deafness leads to enhanced attention in the visual periphery. Yet, whether this enhancement confers advantages in everyday life remains unknown, as deaf individuals have. been shown to be more distracted by irrelevant information in the periphery than their hearing peers. Here, we ~how that, in a complex attentional task, a performance advantage results for deaf individuals. Methodology/Principal Findings: We employed the Useful Field of View (UFOV) which requires central target identification concurrent with peripheral target localization in the presence of distraetors - a divided, selective attention task. First, the comparison of deaf and hearing adults with or without …

On The Approximability Of Dodgson And Young Elections, Ioannis Caragiannis, Jason Covey, Michal Feldman, Christopher Homan, Christos Kaklamanis, Nikos Karanikolas, Ariel D. Procaccia, Jeffrey S. Rosenschein

Articles

The voting rules proposed by Dodgson and Young are both designed to nd the alternative closest to being a Condorcet winner, according to two di erent notions of proximity; the score of a given alternative is known to be hard to compute under either rule. In this paper, we put forward two algorithms for ap- proximating the Dodgson score: an LP-based randomized rounding algorithm and a deterministic greedy algorithm, both of which yield an O(logm) approximation ratio, where m is the number of alternatives; we observe that this result is asymptotically optimal, and further prove that our greedy algorithm is …


An Improvement To Mathon’S Cyclotomic Ramsey Colorings, Xiaodong Xu, Stanislaw Radziszowski Jan 2009

An Improvement To Mathon’S Cyclotomic Ramsey Colorings, Xiaodong Xu, Stanislaw Radziszowski

Articles

In this note we show how to extend Mathon’s cyclotomic colorings of the edges of some complete graphs without increasing the maximum order of monochromatic complete subgraphs. This improves the well known lower bound construction for multicolor Ramsey numbers, in particular we obtain R3(7) ≥ 3214.


Identifying Layout Classes For Mathematical Symbols Using Layout Context, Ling Ouyang, Richard Zanibbi Jan 2009

Identifying Layout Classes For Mathematical Symbols Using Layout Context, Ling Ouyang, Richard Zanibbi

Articles

We describe a symbol classification technique for identifying the expected locations of neighboring symbols in mathematical expressions. We use the seven symbol layout classes of the DRACULAE math notation parser (Zanibbi, Blostein, and Cordy, 2002) to represent expected locations for neighboring symbols: Ascender, Descender, Centered, Open Bracket, Non-Script, Variable Range (e.g. integrals) and Square Root. A new feature based on shape contexts (Belongie et al., 2002) named layout context is used to describe the arrangement of neighboring symbol bounding boxes relative to a reference symbol, and the nearest neighbor rule is used for classification. 1917 mathematical symbols from the University …


Counting Triangles In Some Ramsey Graphs, Andrew Lin, John Mackey Jan 2009

Counting Triangles In Some Ramsey Graphs, Andrew Lin, John Mackey

Articles

We extend Goodman’s result on the cardinality of monochromatic triangles in a 2-colored complete graph to the case of bounding the number of triangles in the first color. We apply it to derive the upper bounds on some non-diagonal Ramsey numbers. In particular we show that R(K4 − e,K8) <= 45.


Single Block Attacks And Statistical Tests On Cubehash, Alan Kaminsky, Benjamin Bloom Jan 2009

Single Block Attacks And Statistical Tests On Cubehash, Alan Kaminsky, Benjamin Bloom

Articles

This paper describes a second preimage attack on the CubeHash cryptographic one-way hash function. The attack finds a second preimage in less time than brute force search for these CubeHash variants: CubeHash $r$/$b$-224 for $b > 100$; CubeHash$r$/$b$-256 for $b > 96$; CubeHash$r$/$b$-384 for $b > 80$; and CubeHash$r$/$b$-512 for $b > 64$. However, the attack does not break the CubeHash variants recommended for SHA-3. The attack requires minimal memory and can be performed in a massively parallel fashion. This paper also describes several statistical randomness tests on CubeHash. The tests were unable to disprove the hypothesis that CubeHash behaves as a random mapping. …


A Precautionary Tale: Separating The Infant From The Fetus, Lawrence Torcello Dec 2008

A Precautionary Tale: Separating The Infant From The Fetus, Lawrence Torcello

Articles

This article confronts growing conservative opposition to abortion based on the slippery slope claim that abortion is morally equivalent to infanticide. By examining the relationship between moral skepticism and precautionary ethics the article promotes completely the permissive position on abortion from conception to birth while consistently rejecting the possibility that such a position entails permissive implications for infanticide. The article introduces and traces the implicit relationship between moral skepticism, the precautionary principle and political liberalism.


Regular Second Order Perturbations Of Binary Black Holes: The Extreme Mass Ratio Regime, Carlos O. Lousto, Hiroyuki Nakano Dec 2008

Regular Second Order Perturbations Of Binary Black Holes: The Extreme Mass Ratio Regime, Carlos O. Lousto, Hiroyuki Nakano

Articles

In order to derive the precise gravitational waveforms for extreme mass ratio inspirals (EMRI), we develop a formulation for the second order metric perturbations produced by a point particle moving in the Schwarzschild spacetime. The second order waveforms satisfy a wave equation with an effective source build up from products of the first order perturbations and its derivatives. We have explicitly regularized this source at the horizon and at spatial infinity. We show that the effective source does not contain squares of the Dirac’s delta and that perturbations are regular at the particle location. We introduce an asymptotically flat gauge …


The Consequences Of Technostress For End Users In Organizations: Conceptual Development And Empirical Validation, T. Ragu-Nathan, Monideepa Tarafdar, Bhanu Ragu-Nathan Dec 2008

The Consequences Of Technostress For End Users In Organizations: Conceptual Development And Empirical Validation, T. Ragu-Nathan, Monideepa Tarafdar, Bhanu Ragu-Nathan

Articles

The research reported in this paper studies the phenomenon of technostress, that is, stress experienced by end users of Information and Communication Technologies (ICTs), and examines its influence on their job satisfaction, commitment to the organization, and intention to stay. Drawing from the Transaction-Based Model of stress and prior research on the effects of ICTs on end users, we first conceptually build a nomological net for technostress to understand the influence of technostress on three variables relating to end users of ICTs: job satisfaction, and organizational and continuance commitment. Because there are no prior instruments to measure constructs related to …


A 60 Ghz Wireless Network For Enabling Uncompressed Video Communication, Harkirat Singh, Jisung Oh, Changyeul Kweon, Xiangping Qin, Huai-Rong Shao, Chiu Ngo Dec 2008

A 60 Ghz Wireless Network For Enabling Uncompressed Video Communication, Harkirat Singh, Jisung Oh, Changyeul Kweon, Xiangping Qin, Huai-Rong Shao, Chiu Ngo

Articles

Uncompressed high-definition video streaming over wireless personal area networks is a challenging problem because of the high data rate requirement and channel variations. With the advances in RF technology and the huge bandwidth available worldwide in the 57–66 GHz millimeter-wave unlicensed spectrum, mmWave WPANs that can support multigigabit transmission are being developed. However, compared to low-frequency signals (2.4 or 5 GHz), mmWave signals are more fragile; indeed, the propagation losses are significantly higher. In this article we present an mmWave system for supporting uncompressed HD video up to 3 Gb/s. The system includes various efficient error protection and concealment schemes …


Optimal Resource Management In The Presence Of A Deleterious Alien Species: A Stochastic Model For An Orchard, Amitrajeet A. Batabyal, Peter Nijkamp Dec 2008

Optimal Resource Management In The Presence Of A Deleterious Alien Species: A Stochastic Model For An Orchard, Amitrajeet A. Batabyal, Peter Nijkamp

Articles

Various plants and resources such as orchards are vulnerable to the detrimental effects of successful invasions by alien animal or plant species. To outline an appropriate policy response, we first use renewal theory to construct a stochastic model of optimal orchard management in the presence of a deleterious alien species. Next, we derive the orchard manager’s long run expected cost (LREC) of orchard management per unit time. Finally, we show that when confronted with a successful biological invasion, the optimal number of trees that need to be removed and replanted in order to keep the orchard under study sustainable in …


Reviewing Digital Scholarship: The Need For Discipline-Based Peer Review, Jeanne Glaubitz Cross Dec 2008

Reviewing Digital Scholarship: The Need For Discipline-Based Peer Review, Jeanne Glaubitz Cross

Articles

Digital scholarship connects scholarly research to students and the public in nontraditional ways. Authors present research in a digital form, which may include links to primary source material and teaching guides. In this format, design and accessibility are important, and unfortunately, those quick to dismiss all digital work as teaching or outreach can overlook the research element. The confusion over what digital scholarship is and how to evaluate it raises questions that can affect promotion and tenure decisions in academic institutions. This paper will examine issues surrounding the availability of peer review for digital scholarship, especially in the field of …


The Pluralistic Universe Of Law Towards A Neo-Classical Legal Pragmatism, Susan Haack Dec 2008

The Pluralistic Universe Of Law Towards A Neo-Classical Legal Pragmatism, Susan Haack

Articles

After a brief sketch of the history of philosophical pragmatism generally, and of legal pragmatism specifically (section 1), this paper develops a new, neo-classical legal pragmatism: a theory of law drawing in part on Holmes, but also on ideas from the classical pragmatist tradition in philosophy. Main themes are the "pluralistic universe" of law (section 2); the evolution of legal systems (section 3); the place of logic in the law (section 4); and the relation of law and morality (section 5).


High Accuracy Imaging Polarimetry With Nicmos, Daniel Batcheldor, G. Schneider, D.C. Hines, G. D. Schmidt, David J. Axon, Andew Robinson, W. Sparks, C. Tadhunter Nov 2008

High Accuracy Imaging Polarimetry With Nicmos, Daniel Batcheldor, G. Schneider, D.C. Hines, G. D. Schmidt, David J. Axon, Andew Robinson, W. Sparks, C. Tadhunter

Articles

The ability of NICMOS to perform high accuracy polarimetry is currently hampered by an uncalibrated residual instrumental polarization at a level of 1.2−1.5%. To better quantify and characterize this residual we obtained observations of three polarimetric standard stars at three separate space-craft roll angles. Combined with archival data, these observations were used to characterize the residual instrumental polarization to enable NICMOS to reach its full polarimetric potential. Using these data, we calculate values of the parallel transmission coefficients that reproduce the ground-based results for the polarimetric standards. The uncertainties associated with the parallel transmission coefficients, a result of the photometric …


Critical Junctures? Privatization Policy In Brazil And Argentina At The Start Of The Century, John Hogan Nov 2008

Critical Junctures? Privatization Policy In Brazil And Argentina At The Start Of The Century, John Hogan

Articles

This paper uses the critical junctures framework developed by Hogan and Doyle (2007) to determine if there were critical junctures in privatization policy in Brazil and Argentina at the start of the 21st century. The framework constitutes a rigorous approach to the identification of crisis, ideational change, and policy change. It is used to examine the economic disasters in Brazil in 1999 and Argentina in 2001. Previously, we would have had to wait decades before making such an assessment, as there were few tools with which to identify critical junctures, and these were usually only effective long after the event.
