Sustainable Development And Market Liberalism's Shotgun Wedding: Emissions Trading Under The Kyoto Protocol, David M. Driesen

Indiana Law Journal

This Article analyzes the international emissions trading regime at the heart of the world's effort to address global warming as a means of exploring broader international governance issues. The trading regime seeks to marry two models of global governance, market liberalism, which embraces markets as the model of global governance, and sustainable development, which seeks to change development patterns to protect future generations.

This Article explores a previously unacknowledged tension between market liberalism's goal of maximizing short-term cost effectiveness and sustainable development's goal of catalyzing technological change for the benefit of future generations.T his Article presents new data and theory …

Income Diversity Within Neighborhoods And Very Low-Income Families, George C. Galster, Jason C. Booza, Jackie M. Cutsinger

Sociology Faculty Research Publications

The past decades have witnessed increasing concern over the family ills engendered by neighborhoods inhabited overwhelmingly by families with limited resources. This study focuses on a different sort of residential context—neighborhoods with substantial income mixing—and the extent to which very low-income (VLI) families—those earning less than 50 percent of the area median income (AMI)—live in them. The study’s primary units of analysis are the 100 largest metropolitan areas in the United States, according to the 2000 Census, and the secondary units of analysis are census tracts. The study specifies six mutually exclusive income groups based on the ratios relative to …

Volume And Cost Implications Of Product Portfolio Complexity, Mark A. Jacobs

MIS/OM/DS Faculty Publications

Business leaders are concerned about the impacts of increasing levels of product portfolio complexity since many sense that complexity related costs such as order management, procurement, and inventory threaten to undermine operational efficiencies and consume profits. Even so, managers do not fully understand the extent and breadth of the impacts of product portfolio complexity. A more complete understanding of the operational effects of product portfolio complexity is lacking partially because researchers have not yet offered a robust theoretical perspective or studied it in a focused controlled way; until now. Herein, measures of product portfolio complexity are developed and related to …

What Does It Mean To Be A Christian?: The Views Of Joseph Smith And Soren Kierkegaard, David L. Paulsen

BYU Studies

The Danish philosopher Søren Kierkegaard (1813-1855) and the American prophet Joseph Smith (1804-1844) both radically critiqued nineteenth-century Christian culture. Though Søren often directed critiques specifically toward the State Church of Denmark, his ultimate target was Christianity as a whole, or simply "Christendom." Joseph's critique singled out no specific church; he also focused on Christianity as a whole. Notwithstanding important differences, Paulsen finds Søren's and Joseph's critiques of nineteenth-century Christendom mutually reinforcing and illuminating. The comparison of Smith's and Kierkegaard's views includes the following ideas: (1) the New Testament church no longer existed, (2) Christian theology had become defiled, (3) the …

Selling The Soul Of Science For A Pot Of Message: Evangelizing Atheism In The God Delusion, Steven C. Walker

BYU Studies

Bestseller lists for the past two years chart a swelling tide of interest in a long-standing backwater: atheism. Nothing so tame as old-fashioned agnostic doubt, the new wave floods readers with outspoken scientific atheism. Sam Harris’s The End of Faith (2004) was the earthquake that triggered a tsunami swollen by urgent tributaries from Daniel C. Dennett’s Breaking the Spell: Religion as a Natural Phenomenon (2006) and Marc D. Hauser’s Moral Minds (2006), swelled all the more by Harris’s reprise Letter to a Christian Nation (2006). That atheist tidal wave has yet to crest—Carl Sagan hectors us from the grave in …

Radial Velocities Of Giant Stars: An Investigation Of Line Profile Variations, S. Hekker, I. A. G. Snellen, C. Aerts, A. Quirrenbach, S. Reffert, D. S. Mitchell

Physics

Since 1999, a radial velocity survey of 179 red giant stars is ongoing at Lick Observatory with a one month cadence. At present~20—100 measurements have been collected per star with an accuracy of 5 to 8 ms^-1. Of the stars monitored, 145 (80%) show radial velocity (RV) variations at a level >20 ms^-1, of which 43 exhibit significant periodicities. Here, we investigate the mechanism causing the observed radial velocity variations. Firstly, we search for a correlation between the radial velocity amplitude and an intrinsic parameter of the star, in this case surface gravity (logg). …

The Relationship Between Crystal Structure And Nmr Relaxation In Molecular Solids With Tert-Butyl Groups, Arnold L. Rheingold, Antonio G. Dipasquale, Peter A. Beckmann

Physics Faculty Research and Scholarship

We correlate an X-ray determination of the molecular and crystal structures of 2-tert-butylanthracene and 2-tert-butylanthraquinone reported here with the previously reported dynamical nuclear magnetic resonance determination of the motions of the tert-butyl groups and their resident methyl groups in the solid state [P.A. Beckmann, K.S. Burbank, M.M.W. Lau, J.N. Ree, T.L. Weber, Chem. Phys. 290 (2003) 241].

Games, Robots, And Robot Games: Complementary Contexts For Introductory Computing Education, Dianna Xu, Doug Blank, Deepak Kumar

Computer Science Faculty Research and Scholarship

Using games to teach introductory computing courses provides another context with which to exploring the possible attraction, retention, and education of a new generation of computer science (CS) students. At Bryn Mawr College, we have been actively exploring these contexts and have identified four that have great promise for use in teaching introductory computing courses: visualization, multimedia, robotics, and, most recently, games. We are currently using and analysing robots and have some preliminary results. We believe that much of what we have learned in using robots in the classroom can be applied to the other contexts, especially gaming. In addition, …

A basic problem in contact topology is to determine whether two Legendrian knots or links are equivalent. In this dissertation, we will study the equivalence and non-equivalence of Legendrian links that are topologically torus links.

A Faculty Workshop On Student Assessment, Iris M. Totten, Kirsten Nicolaysen, Sheryl Hodge, Mary S. Hubbard

Geosciences Faculty Publications

A faculty workshop was conducted that showcased assessment activities that could be incorporated into undergraduate and graduate geology courses. Fourteen different types of student assessment were presented. Workshop participants were asked to respond to questions about their familiarity and use of each type before and immediately following the workshop. In addition, they were asked to indicate how likely they would be to incorporate each type of assessment in their student grading practices in the future. Results suggest relatively high familiarity and use of the more traditional types of assessments (e.g., instructor- and commercially-produced pencil and paper exams, group projects, and …

Strike-Slip Fault Terminations At Seismogenic Depths: The Structure And Kinematics Of The Glacier Lakes Fault, Sierra Nevada United States, J. D. Kirkpatrick, Z. K. Shipton, James P. Evans, S. Micklethwaite, S. J. Lim, Peter R. Mckillop

Geosciences Faculty Publications

[1] Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth. The 8.2 km long Glacier Lakes fault (GLF) in the Sierra Nevada is a left-lateral strike-slip fault with a maximum observed displacement of 125 m. Within the fault, pseudotachylytes crosscut cataclasites, showing that displacement on the GLF was accommodated at least partly by seismic slip. The western termination of the GLF is defined by a gradual decrease in the displacement on the main fault, accompanied by a 1.4 km wide zone of secondary …

Development Of Neuro-Fuzzy Models To Account For Temporal And Spatial Variations In A Lumped Rainfall-Runoff Model, Ahmed Nasr, Michael Bruen

Articles

For many good and practical reasons, lumped rainfall-runoff models are widely used to represent a catchment‟s response to rainfall. However, they have some acknowledged limitation, some of which are addressed here using a neuro-fuzzy model to combine, in an optimal way, a number of lumped-sub-models. For instance, to address temporal variation, one of the sub-models in the combination may perform well under flood conditions and another under drier conditions and the neuro- fuzzy system would combine their outputs for each time-step in a manner depending on the prevailing conditions. Similarly to address spatial variation, one of the sub-models may perform …

Integrating Engineering Ethics And Research Skills In A First Year Programme, Eddie Conlon

Conference papers

A first year module which introduces students to the social dimension of engineering is described. The key teaching tool is the use of group projects to develop students’ learning skills. The importance of addressing the motivation for engineering students studying non-technical modules is emphasised. Data used to evaluate the module is presented. It is shown that the nature of the project undertaken affects the attainment of learning outcomes. The conclusion focuses on some shortcomings of the module and highlights the importance of appropriately structuring the learning environment to facilitate self-directed learning by early year students.

Volcanic Activity: Processing Of Observation And Remote Sensing Data (Vapor), Mark Wylie

Reports

The World Bank makes a very clear distinction between disasters and natural phenomena. Natural phenomena are events like volcanic eruptions. A disaster only occurs when the ability of the community to cope with natural phenomenon has been surpassed, causing widespread human, material, economic or environmental losses. By these definitions, volcanic eruptions do not have to lead to disasters. On November 13, 1985, the second most deadly eruption of the twentieth century occurred in Colombia. Within a few hours of the eruption of the Nevado del Ruiz volcano, 23,000 people were dead because no infrastructure existed to respond to such an …

Evaluation Of A Naive Model For Square Wave Voltammetry At A Microelectrode, Patrick Enright, John Cassidy, Tony Betts

Articles

A square wave voltammetric waveform ( SWV) was applied to an inlaid microdisk electrode in a solution of K4[Fe(CN)6]. A simple model relying on the assumption of steady state current throughout the scan was used to model the current potential behaviour. However, experimental peak current magnitudes were between 30% and 50% greater than those predicted by the model. The model predicts an increase of peak current and peak width at half height with pulse height Esw and no effect of the parameters frequency, f and step height, ΔEs. Experimental peak current magnitudes and peak current magnitudes predicted by the model …

Generation Of High-Repetition-Rate Pulses Utilizing Cascaded Single Mode Fiber And Semiconductor Optical Amplifier, Jianwei Wu, Hai-Bo Bao

Turkish Journal of Electrical Engineering and Computer Sciences

To generate high-repetition-rate optical pulses, a novel and simple device is demonstrated, in which the cascaded single mode fiber (SMF) with negative third order dispersion and semiconductor optical amplifier (SOA) are adopted. Numerical research results show that let an optical pulse with center wavelength in zero dispersion wavelength of optical fiber transit in SMF for generating an oscillation pulse. Subsequently, the followed SOA is provided for amplification. As a consequence, the high-repetition-rate optical pulses can be obtained.

A Study On The Reliability Of Polyester Insulators Blended With Borax, Aysel Ersoy, Yasi̇n Özcelep, Ayten Kuntman

Turkish Journal of Electrical Engineering and Computer Sciences

Tracking is the main factor which limits the safe working electric stress of insulation in power system applications. Polymer samples have been tested in laboratory conditions according to ASTM D2303 on accelerated inclined plane tracking test. In this paper, a model based on improved Weibull statistics is proposed for estimating the breakdown time of polymeric insulating materials with borax. The confidence intervals of the Weibull shape parameter and the Weibull scale parameter are determined for the borax concentration values using the Weibull 7++ program.

Relative Searching Using An Ordered Token List, Anthony Rosequist

Inquiry: The University of Arkansas Undergraduate Research Journal

Many organizations have large amounts of information, such as consumer data, that need to be processed. Traditional searching algorithms only attempt to find exact matches to particular queries. This is undesirable when data are missing, outdated, or inaccurate. Therefore, a new type of search must be developed to locate records that are considered "interesting" to the user. This research paper examines past attempts to solve this problem and explores a new method involving ordered token lists to achieve this goal. The algorithm was developed, implemented, tested, and optimized.

Luminescent Solar Concentrators: A Review Of Recent Results, Wilfrid G.J.H.M. Van Sark, Keith W.J. Barnham, Lenneke H. Slooff, Amanda J. Chatten, Andreas Buchtemann, Andreas Meyer, Sarah Mccormack, Rolf Koole, Daniel J. Farrell, Rahul Bose, Evert E. Bende, Antonius R. Burgers, Tristram Budel, Jana Quilitz, Manus Kennedy, Toby Meyer, C. De Mello Donega, Andries Meijerink

Articles

Luminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells. LSCs offer potentially lower cost per Wp. This paper reviews results mainly obtained within the framework of the Fullspectrum project. Two modeling approaches are presented, i.e., a thermodynamic and a ray-trace one, as well as experimental results, with a focus on LSC stability.

Application Of The Fractal Market Hypothesis For Modelling Macroeconomic Time Series, Jonathan Blackledge

Articles

This paper explores the conceptual background to financial time series analysis and financial signal processing in terms of the Efficient Market Hypothesis. By revisiting the principal conventional approaches to market analysis and the reasoning associated with them, we develop a Fractal Market Hypothesis that is based on the application of non-stationary fractional dynamics using an operator of the type
∂² / ∂x² − σ^q(t) * ∂ ^q(t)/ ∂t^q(t)

where σ⁻¹ is the fractional diffusivity and q is the Fourier dimension which, for the topology considered, (i.e. the one-dimensional case) is related to the Fractal …
