e-Government awareness among the techno-disadvantaged in the United States
This exploratory research focuses on awareness among techno-disadvantaged citizens in the United States. Specifically, we address whether awareness is associated with visitation and whether there are differences between those who are aware and those who are not aware. Following up on on a theory-based community initiative designed to improve computer literacy and access to information and communication technologies (ICT) for members of an underserved public housing community, a survey was undertaken. The results indicate that awareness is associated with visitation. Differences in demographic characterisitics, perceived ease of use (PEOU), and perceived access barriers between those who are aware of e-government websites, and those who are not, were found. While nearly half of the respondents are neither aware of nor have visited e-government websites, a slight majority is partaking of e-government services. We identify directions for future research and conclude by emphasizing the value of a theory-based community initiative to improve computer literacy, provide access to ICT, and advance e-government inclusion
Galactic extinction and Abell clusters
In this paper, we present the results of comparing the angular distribution
of Abell clusters with Galactic HI measurements. For most subsamples of
clusters considered, their positions on the sky appear to be anti-correlated
with respect to the distribution of HI column densities. The statistical
significance of these observed anti-correlations is a function of both richness
and distance class, with the more distant and/or richest systems having the
highest significance (~3 sigma). The lower richness, nearby clusters appear to
be randomly distributed compared to the observed Galactic HI column density.Comment: 5 pages, uuencoded compressed postscript file. Figures included.

A Comparison of Continuously Controlled and Controlled K-theory
We define an unreduced version of the e-controlled lower -theoretic groups
of Ranicki and Yamasaki, and Quinn. We show that the reduced versions of our
groups coincide (in the inverse limit and its first derived, ) with
those of Ranicki and Yamasaki. We also relate the controlled groups to the
continuously controlled groups of Anderson and Munkholm, and to the Quinn
homology groups of Quinn
Protecting Menardâs Quixote: A Return to the Strict Originality Standard in Copyright Law
Copyright protection extends to âoriginalâ works. The adjective âoriginalâ here means a work that originated with its purported author, and is not meant to impute any novelty requirement to copyright law. However, case law and literature offer up several odd examples where two individuals have independently created identical works of art. The theory underlying copyright law requires that, because each work originated independently from separate authors, each work be independently copyrightable. Applying this strict, objective standard of originality to the transformative arts, we begin to see new possibilities for grounding copyrights in parodies and satires. Under current law, parodies escape infringement of their target works through the âfair useâ exception to copyright law, while satires frequently do not. However, this essay argues that, under a strict interpretation of the originality standard, parodies and satires alike can be considered independently created works of art that are not derivative of (and hence not infringing) their target works. This essay suggests the application of a new standard of ascertainably different meanings when determining whether one work infringes upon a similar work
Are the Earth and the Moon compositionally alike? Inferences on lunar composition and implications for lunar origin and evolution from geophysical modeling
The main objective of the present study is to discuss in detail the results obtained from an inversion of the Apollo lunar seismic data set, lunar mass, and moment of inertia. We inverted directly for lunar chemical composition and temperature using the model system CaO-FeO-MgO-Al2O3-SiO2. Using Gibbs free energy minimization, stable
mineral phases at the temperatures and pressures of interest, their modes and physical properties are calculated. We determine the compositional range of the oxide elements, thermal state, Mg#, mineralogy and physical structure of the lunar interior, as well as constraining core size and density. The results indicate a lunar mantle mineralogy that is dominated by olivine and orthopyroxene ( 80 vol%), with the remainder being composed of clinopyroxene and an aluminous phase (plagioclase, spinel, and garnet present in the depth ranges 0â150 km, 150â200 km, and >200 km, respectively). This model is broadly
consistent with constraints on mantle mineralogy derived from the experimental and
observational study of the phase lationships and trace element compositions of lunar
mare basalts and picritic glasses. In particular, by melting a typical model mantle
composition using the pMELTS algorithm, we found that a range of batch melts generated
from these models have features in common with low Ti mare basalts and picritic glasses. Our results also indicate a bulk lunar composition and Mg# different to that of the Earthâs upper mantle, represented by the pyrolite composition. This difference is reflected in a lower bulk lunar Mg# ( 0.83). Results also indicate a small iron-like core with a radius around 340 km.The Carlsberg Foundation, NER
