Sheff V. O'Neill: The Consequences Of Educational Table-Scraps For Poor Urban Minority Schools, Alicia L. Mioli

Fordham Urban Law Journal

This Note explores the debate between colorblindness and race consciousness while arguing that the multidistrict integration remedy called for by Sheff v. O'Neill does not directly address the true injury faced by minority students: inferior education. It examines the facts and background on the Sheff decision as well as other Connecticut cases involving school funding. Colorblind and race conscious theory is outlined as well as how each theory interacts with education. The Note concludes by explaining how integrationalists are missing the solution to the educational problems faced by minority students and how the true solution to them are not backward-looking, …

A Mathematical Model For Spatially Varying Extracellular Matrix, J. C. Dallon, J. A. Sherratt

Faculty Publications

Orientation of extracellular matrix fibers in the skin is a key ingredient of tissue appearance and function, and differences in fiber alignment are one of the main distinctions between scar tissue and normal skin. In this paper, the authors develop a mathematical model for alignment of collagen fibers and the fibroblast cells that remodel them; the model extends previous work in which spatial variation was excluded. Numerical simulations of the model are presented, which show spatial variations in alignment over long transients, but with spatially uniform behavior in the long term. This is investigated further via asymptotic analysis, using the …

Neutron Scattering From Aerosols: Intraparticle Structure Factor, Guinier Analysis Of Particle Speed, And Crossed Beam Kinematics, Gerald Wilemski

Physics Faculty Research & Creative Works

A theoretical formalism for neutron scattering from systems of particles is applied to liquid nanodroplet aerosols. A term arising from intraparticle, intermolecular correlations is identified. The kinematical theory of two body scattering is recast into a form convenient for interpreting the results of experiments with crossed beams of neutrons and aerosol particles. Based on a theoretical analysis of the scattered intensity in the Guinier region, a method for determining the particle velocity directly from the experimental data is outlined. The method is not restricted by assumptions about particle shape, composition, uniformity, or size distribution.

A Qualitative Evaluation Of Teaming, Problem -Solving, And Technology -Utilization Skills Of Students In The Integrated First-Year Curriculum In Science, Engineering, And Mathematics, Jean Kathryn Sando

All-Inclusive List of Electronic Theses and Dissertations

In 1993, Rose-Hulman Institute of Technology became a member of the Foundation Coalition, one of six EngineeringEducation Coalitions sponsored by grants from the National Science Foundation. Experimental curricula were created, including the Integrated First Year Curriculum in Science, Engineering, and Mathematics (IFYCSEM) and the Sophomore Engineering Program (SEC). In this study, students who completed one or more of the Foundation Coalition curricula were placed in four-member teams and comparatively evaluated using qualitative research techniques for their abilities to work in teams, to solve complex, open-ended problems and to utilize technology. This study evaluated the outcomes for the students at Rose-Hulman …

Silver(I) Complexation Of (Poly)Aromatic Ligands. Structural Criteria For Depth Penetration Into Cis-Stilbenoid Cavities, Sergey V. Lindeman, Rajendra Rathore, Jay K. Kochi

Chemistry Faculty Research and Publications

Silver(I) complexes with aromatic donors are thoroughly analyzed (with aid of the Cambridge Crystallographic Database) to identify the basic structural factors inherent to the bonding of an arene ligand. Most strikingly, the distance parameter d (which simply measures the normal separation of Ag from the mean aromatic plane) is singularly invariant at d = 2.41 ± 0.05 Å for all silver/arene complexes, independent of the hapticity (η¹ or η²), hybridization, or multiple coordination. As such, a systematic series of stilbenoid ligands has been successfully designed to precisely modulate the penetration of silver(I) into the ligand cleft, and …

Novel (Heteromolecular) Π-Complexes Of Aromatic Cation Radicals. Isolation And Structural Characterization, P. Le Maguères, Sergey V. Lindeman, Jay K. Kochi

Chemistry Faculty Research and Publications

Extensive (electron) delocalization in the novel heteromolecular π-complex of the hindered naphthalene cation radical (OMN^+•) with naphthalene (NAP) accompanies the pronounced charge-transfer absorption band at ∼1100 nm in the near-IR. X-ray crystallography establishes the viability of the unusual “club sandwich” structure despite the repulsive electrostatic forces inherent to the dicationic unit.

The Impact Of The Ohio Lottery On Public Primary And Secondary Schools In Montgomery County, Delores Davis

Masters Culminating Experiences (1993-2011)

In 1974, voters in the state of Ohio approved the institution of a lottery as a means to raise funds for their public primary and secondary schools. According to the legislative history of the Ohio Lottery, the purpose for the lottery is to provide a means for relatively poor school districts to enhance their own local tax base such that more public school funds could be produced locally to meet the special needs of their primary and secondary schools. Lottery operations have been conducted in most school districts for more than a quarter of a century. For a number of …

Imprecise Answers In Distributed Environments: Estimation Of Information Loss For Multi-Ontology Based Query Processing, Eduardo Mena, Vipul Kashyap, Arantza Illarramendi, Amit P. Sheth

Kno.e.sis Publications

The World Wide Web is fast becoming a ubiquitous computing environment. Prevalent keyword-based search techniques are scalable, but are incapable of accessing information based on concepts. We investigate the use of concepts from multiple, real-world pre-existing, domain ontologies to describe the underlying data content and support information access at a higher level of abstraction. It is not practical to have a single domain ontology to describe the vast amounts of data on the Web. In fact, we expect multiple ontologies to be used as different world views and present an approach to "browse" ontologies as a paradigm for information access. …

Optimization Techniques For Data Intensive Decision Flows, Richard Hull, Francois Llirbat, Bharat Kumar, Gang Zhou, Guozhu Dong, Jianwen Su

Kno.e.sis Publications

For an enterprise to take advantage of the opportunities afforded by electronic commerce it must be able to make decisions about business transactions in near-real-time. In the coming era of segment-of-one marketing, these decisions will be quite intricate, so that customer treatments can be highly personalized, reflecting customer preferences, the customer's history with the enterprise, and targeted business objectives. This paper describes a paradigm called “decision flows” for specifying a form of incremental decision-making that can combine diverse business factors in near-real-time.

This paper introduces and empirically analyzes a variety of optimization strategies for decision flows that are “data-intensive”, i.e. …

Geologic Factors Controlling Patterns Of Small‐Volume Basaltic Volcanism: Application To A Volcanic Hazards Assessment At Yucca Mountain, Nevada, Charles B. Connor, John A. Stamatakos, David A. Ferrill, Brittain E. Hill, Goodluck I. Ofoegbu, Michael Conway, Budhi Sagar, John Trapp

School of Geosciences Faculty and Staff Publications

The proposed high‐level radioactive waste repository at Yucca Mountain, Nevada, is located within an active volcanic field. Probabilistic volcanic hazard models for future eruptions through the proposed repository depend heavily on our understanding of the spatial controls on volcano distribution at a variety of scales. On regional scales, Pliocene‐Quaternary volcano clusters are located east of the Bare Mountain fault. Extension has resulted in large‐scale crustal density contrast across the fault, and vents are restricted to low‐density areas of the hanging wall. Finite element modeling indicates that this crustal density contrast can result in transient pressure changes of up to 7 …

Gps Geodetic Constraints On Caribbean-North America Plate Motion, Charles Demets, Pamela E. Jansma, Glen S. Mattioli, Timothy H. Dixon, Fred Farina, Roger Bilham, Eric Calais, Paul Mann

School of Geosciences Faculty and Staff Publications

We describe a model for Caribbean plate motion based on GPS velocities of four sites in the plate interior and two azimuths of the Swan Islands transform fault. The data are well fit by a single angular velocity, with average misfits approximately equal to the 1.5–3.0 mm yr⁻¹ velocity uncertainties. The new model predicts Caribbean-North America motion ∼65% faster than predicted by NUVEL-1A, averaging 18–20±3 mm yr⁻¹ (2σ) at various locations along the plate boundary. The data are best fit by a rotation pole that predicts obliquely convergent motion along the plate boundary east of Cuba, but are …

Neotectonics Of Puerto Rico And The Virgin Islands, Northeastern Caribbean, From Gps Geodesy, Pamela E. Jansma, Glen S. Mattioli, Alberto Lopez, Charles Demets, Timothy H. Dixon, Paul Mann, Eric Calais

School of Geosciences Faculty and Staff Publications

The boundary between the North American and Caribbean plates is characterized primarily by left-lateral motion along predominantly east-west striking faults. Seismicity and marine geophysical survey data are consistent with at least two, and possibly three, microplates in the diffuse boundary zone in the northeastern Caribbean: (1) the Gonave, (2) the Hispaniola, and (3) the Puerto Rico-northern Virgin Islands (PRVI). We discuss results from GPS geodetic measurements acquired since 1994 to test the microplate hypothesis, define PRVI translation and rotation within the boundary zone, and constrain PRVI neotectonics. GPS-derived velocities are analyzed with respect to both North American and Caribbean plate …

Magnetic Confinement, Magnetohydrodynamic Waves And Smooth Line Profiles In Active Galactic Nuclei, M. C. Bottorff, Gary J. Ferland

Physics and Astronomy Faculty Publications

In this paper, we show that if the broad-line region clouds are in approximate energy equipartition between the magnetic field and gravity, as hypothesized by Rees, there will be a significant effect on the shape and smoothness of broad emission-line profiles in active galactic nuclei. Linewidths of contributing clouds or flow elements are much wider than their thermal widths, because of the presence of non-dissipative magnetohydrodynamic waves and their collective contribution produce emission-line profiles broader and smoother than would be expected if a magnetic field were not present. As an illustration, a simple model of isotropically emitting clouds, normally distributed …

One Professor's Approach To Increasing Technology Use In Legal Education, Shelley Ross Saxer

Richmond Journal of Law & Technology

Legal educators must increase the use of technology in legal education today Although some legal educators may disagree vehemently with this statement, most have accepted the fact that technology has and will become an even greater part of the fabric of our learning institutions. Students in kindergarten spend some portion of their week in the computer lab. By the time kids reach their middle- and high-school years, many are well-versed in word processing programs, e-mail, and surfing the Internet. Elementary school teachers are trained and encouraged to use multi-media software, the Internet, and other technology in their classrooms because not …
