A Sabbatical View Of Educational Technology, Margaret E. Curran

Journal of Catholic Education

Catholic schools throughout the country are actively engaged in the process of integrating technology into their schools. A wide range of programs exists, and those programs are at various stages of development. The author visited a sample of schools that have a strong technology emphasis and identifies key elements within those programs. A review of those elements can be helpful in creating new programs.

A Comparative Analysis Of Spectral Band Selection Techniques, Julia Laurenzano

Theses

The ability to determine optimal spectral band sets for the exploitation of multispectral and hyperspectral imagery is of great concern due to data transfer, storage, and computational constraints. This study compares the performance of three band selection techniques across a range of scenarios and image exploitation algorithms. Thresholded Divergence, a technique based on Gaussian Maximum Likelihood classification, Forward Sequential Band Selection, an iterative method based on target identification algorithms, and Spectral Basis Functions, a method independent of end-exploitation, were selected for evaluation. Each of these band selection techniques was applied to two M7 multispectral images and two HYDICE hyperspectral images. …

Three Theories Of Development: A Comparison Of Dewey, Kohlberg, And Noddings' Models Of Moral Growth, Mark J. Connerty

Critical and Creative Thinking Capstones Collection

This paper will compare the moral theories developed by John Dewey, Lawrence Kohlberg, and Nel Noddings to discern places of agreement and areas of dispute. The paper will also examine the most consequential ethical formulations of the three thinkers. For Dewey it is his conception of conscientiousness. For Kohlberg it is the idea of justice. Lastly, for Noddings it is the virtue of empathy found in the caring response. These conceptions are the foundations of their moral ideas. They color their thoughts on such related topics as the objective versus subjective nature of morality, the role of the rational and …

Broadband Optical Observations Of Bl Lacertae During The 1997 Outburst, Terry D. Oswalt, Daniel Marshall, Tim Robishaw

Aerospace, Physics, and Space Science Faculty Publications

We present BVRI observations of BL Lacertae during its recent outburst. These observations, made during a 3 month period, cover a significant portion of the optical flare. The reduced data are displayed as light curves and broadband spectra. Changes in the spectral index are analyzed, and the results are compared with previous BL Lac observations. We find that the variations are simultaneous in the optical bands, but the higher frequency bands show a higher amplitude of variability. The spectral index is variable during the active period, and there is marginal evidence that the spectrum flattens as the source gets brighter.

Dynamically Maintained Steady-State Pressure Gradients, D. P. Sheehan

Physics and Biophysics: Faculty Scholarship

In a sealed blackbody cavity with gas, pressure gradients commonly take three forms: (a) statistical fluctuations, (b) transients associated with the system relaxing toward equilibrium, and (c)equilibrium pressure gradients associated with potential gradients (such as with gravity). In this paper, it is shown that in the low-density (collisionless) regime, a fourth type of pressure gradient may arise, this due to steady-state differential thermal desorption of surface species from chemically active surfaces. This gas phase is inherently nonequilibrium in character. Numerical simulations using realistic physical parameters support the possibility of this gas phase and indicate that these novel pressure gradients might …

Four Paradoxes Involving The Second Law Of Thermodynamics, D. P. Sheehan

Physics and Biophysics: Faculty Scholarship

Recently four independent paradoxes have been proposed which appear to challenge the second law of thermodynamics [1-8]. These paradoxes are briefly reviewed. It is shown that each paradox results from a synergism of two broken symmetries - one geometric, one thermodynamic

Nanostructured Ndfeb Films Processed By Rapid Thermal Annealing, M. Yu, Yi Liu, Sy_Hwang Liou, David J. Sellmyer

Sy-Hwang Liou Publications

Nanostructured NdFeB films were prepared by magnetron sputtering followed by rapid thermal annealing at a ramp rate of 200 °C/s. Isotropically oriented Nd₂Fe₁₄B crystallites were formed in the films and coercivities up to 20 kOe and remanence ratios up to 0.8 were obtained. Transmission electron microscopy analysis shows that the majority phase of the magnetic layer in the high coercivity films consists of Nd₂Fe₁₄B nanocrystallites with an average size of about 50 nm. These nanocrystallites are believed to be single-domain particles, which are responsible for the high coercivities. MFM measurements show that …

Japanese Economic Exploitation Of Central Pacific Seabird Populations, 1898–1915, Dirk H. R Spennemann

Pacific Studies

At the turn of the century, Japanese feather and plumage hunters visited most of the isolated, uninhabited atolls of the central Pacific Ocean. The seabird populations of these atolls were decimated to supply exotic feathers for the millinery market to meet an increasing demand created by the European fashion industry. Drawing on scattered archival records, this article reviews the history and dimensions of the feather trade in the Central Pacific and describes the responses of the affected nations.

Image Processing Based On A Fuzzy Logic Edge Detection Algorithm, Jamshid Khazaai

Masters Theses

One of the major problems in image processing is that of efficient edge detection. This is because the automated determination of an edge requires a subjective interpretation of just what the image author intended to be an edge. By training an edge determination algorithm to be sensitive to edges in a consistent manner, efficiency can be improved. This is the central idea of this thesis in which I define edge occurrences for the intensity (monochrome) images using fuzzy sets.

Edge characteristic functions are proposed for detecting edge pixels within a desired block of an (intensity and binary) image based on …

The Implementation Of Group Mentoring Between At-Risk Teenage African American Males And Successful Adult African American Men, Cornell Mathis

Masters Theses

Little research has been done to examine the implementation of group mentoring. This study of group mentoring involving at-risk teenage African American males and successful adult African American men will provide insight into group mentoring as demonstrated through interpersonal communications.

An investigation of the composite reduction provides the foundation for establishing the following definition of the group mentoring experience. The mentees are drawn to the mentors by mutual respect developed through the use of a special language. Availability leads to bonding between the mentees and mentors. The relationships are fostered by the authenticity of both individuals while producing social enlightenment …

Analysis Of Hydric Pine Flatwood Ephemeral Pool Macroinvertebrate And Crustacean Assemblages Along A Temporal And Spatial Gradient From A Hypothesized Colonial Source, Henry Leon Griffith

Theses and Dissertations

A survey of the macroinvertebrate and crustacean assemblages in hydric pine flatwood wetlands during fill and drawdown periods was conducted from September to November 1998, in Lee County, Florida. Physical and chemical information, relationships between community composition and physical and chemical conditions were analyzed and a monitoring plan for detecting impacts of declining water supply in hydric pine flatwood communities was proposed. In addition, possible sources of colonists and patterns of community assemblage were investigated. Twelve ephemeral pools and three associated intermittently exposed cypress heads were sampled monthly, over three months, using 1 D-ring benthic sweep, 2 Hester-Dendy multiple plate …

Gps Measurements Across The Northern Caribbean Plate Boundary Zone: Impact Of Postseismic Relaxation Following Historic Earthquakes, Fred F. Pollitz, Timothy H. Dixon

School of Geosciences Faculty and Staff Publications

GPS measurements in the northern Caribbean suggest that the rate of Caribbean plate motion relative to North America is about 10 mm/yr faster than predicted by global plate motion model NUVEL-1A. Several of the key sites used in the GPS study are located in the Dominican Republic, near the rupture zones of large earthquakes in 1946 and in the previous two centuries. Postseismic relaxation of the crust and upper mantle is a possible explanation for the plate velocity discrepancy. We explore a range of fault mechanisms and crustal and mantle rheology to place an upper bound on postseismic relaxation effects. …

Estimate Of Bottom And Surface Stress During A Spring-Neap Tide Cycle By Dynamical Assimilation Of Tide Gauge Observatons In The Chesapeake Bay, Y. H. Spitz, J. M. Klinck

CCPO Publications

Dynamical assimilation of surface elevation from tide gauges is investigated to estimate the bottom drag coefficient and surface stress as a first step in improving modeled tidal and wind-driven circulation in the Chesapeake Bay. A two-dimensional shallow water model and an adjoint variational method with a limited memory quasi-Newton optimization algorithm are used to achieve this goal. Assimilation of tide gauge observations from 10 permanent stations in the Bay and use of a two-dimensional model adequately estimate the bottom drag coefficient, wind stress, and surface elevation at the Bay mouth. Subsequent use of these estimates in the circulation model considerably …

Ranking And Explaining The Scholarly Impact Of Law Schools, Theodore Eisenberg, Martin T. Wells

Cornell Law Faculty Publications

This article measures 32 law schools' academic reputations by citations to their faculties' works. Yale, Chicago, Harvard, and Stanford rank alone at the top. Seven or eight schools compose the next group. We also explore the relation between scholarly impact and entry-level or lateral hire status, gender, minority status, subjects taught, and years in teaching. Lateral hires systematically outperform entry-level hires. We find no substantial evidence of male-female differences. We find some evidence of lower citations for minority females, but this difference is largely attributable to those in teaching fewer than 8 years. For faculty members in teaching more than …

Attempting To Legislate Attempted Environmental Crimes, Helen M. Maher

Pace Environmental Law Review

The Environmental Crimes and Enforcement Act of 1996 (ECEA) bill was recently proposed for consideration by Congress. The ECEA, if adopted, will have a pervasive effect on the entire spectrum of environmental statutes, reflecting a legislative effort to create more uniform enforcement and penalty provisions. Most importantly, the bill creates liability for any person who attempts to violate an environmental statute. This Comment analyzes the ECEA and focuses specifically on the attempt provision and its impact on the Clean Water Act. The underlying rationales and social purposes of common law approaches to environmental regulation will be compared with the proposed …

Parallel Linear Congruential Generators With Prime Moduli, Michael Mascagni

Faculty Publications

Linear congruential generators (LCGs) remain the most popular method of pseudorandom number generation on digital computers. Ease of implementation has favored implementing LCGs with power-of-two moduli. However, prime modulus LCGs are superior in quality to power-of-two modulus LCGs, and the use of a Mersenne prime minimizes the computational cost of generation. When implemented for parallel computation, quality becomes an even more compelling issue. We use a full-period exponential sum as the measure of stream independence and present a method for producing provably independent streams of LCGs in parallel by utilizing an explicit parameterization of all of the primitive elements module …

A Study Of The Knowledge Structure Of Expert, Intermediate, And Novice Subjects In The Domain Of Physics, Jennifer L. Discenna

Dissertations

The objective of this research was to investigate the knowledge structure in physics by describing the knowledge of experts, intermediates, and novices. A review of the literature on expertise, physics knowledge, and conceptual structure provided two competing representations of physics knowledge: one defined as a hierarchy of models arranged from general to specific models, the second defined by theories which link knowledge together.

In order to investigate the two representations described above, a reiterative categorization task was employed. This task resulted in a hierarchical sort with larger piles at the top of the hierarchy and smaller piles at the bottom …

Surface Models Of Finite Geometries, Ramon Manuel Figueroa-Centeno

Dissertations

The standard non-Euclidean geometries, hyperbolic geometry and elliptical geometry, both arise by negating the parallel postulate of Euclid. Both these geometries share with Euclidean geometries an infinitude of points and lines. But also possible are many finite geometries. Among these are the class of projective geometries PG(m,q) of projective dimension m (m > 2) and the k-configurations. These mathematical objects, although primarily geometric in nature, provide related structures of combinatorial interest: block designs. These have applications in scheduling problems and the design of experiments for statistical analysis. Recently, A. T. White has added a topological flavor to the study …
