Hip Hop Hermeneutics: How the Culture Influences Preachers
Hip Hop Hermeneutics essay lays out findings of current research into how Hip Hop culture has been formational for African American preachers, and how that culture informs their preaching. There is a generation of preachers leading congregations today that have grown up with Hip Hop. Hip Hop culture has left an indelible mark upon them; just as the church has. How does the cultural influence of Hip Hop affect their preaching? Hip Hop hermeneutics is the response put forth by this article. This article traces the practice and theology of early African American preachers, the work of James Cone in Black Liberation theology, and Womanist theologians to demonstrate how Black theology has always included the Black experience as part of its theological norm. The article then posits that the next generation of Black theology must take into account that Hip Hop is also part of that Black experience, before going on to delineate a Hip Hop hermeneutic. A Hip Hop hermeneutic is a particular way of reading scripture that embraces the honest and raw fullness of the Black experience
North Slope Borough water study: a background for planning
The Planning and Research Section of Alaska Dept. of Natural
Resources initiated this pilot water study with the North Slope Borough
and the University of Alaska's Arctic Environmental Information and Data
Center and Institute of Water Resources. Traditional and present water
uses in the eight North Slope Borough villages are examined to assist in
evaluating and planning for present and future water use, treatment, and
disposal requirements.Prepared for

Stability analysis of perturbed plane Couette flow
Plane Couette flow perturbed by a spanwise oriented ribbon, similar to a
configuration investigated experimentally at the Centre d'Etudes de Saclay, is
investigated numerically using a spectral-element code. 2D steady states are
computed for the perturbed configuration; these differ from the unperturbed
flows mainly by a region of counter-circulation surrounding the ribbon. The 2D
steady flow loses stability to 3D eigenmodes at Re = 230, beta = 1.3 for rho =
0.086 and Re = 550, beta = 1.5 for rho = 0.043, where Re is the Reynolds
number, beta is the spanwise wavenumber and rho is the half-height of the
ribbon. For rho = 0.086, the bifurcation is determined to be subcritical by
calculating the cubic term in the normal form equation from the timeseries of a
single nonlinear simulation; steady 3D flows are found for Re as low as 200.
The critical eigenmode and nonlinear 3D states contain streamwise vortices
localized near the ribbon, whose streamwise extent increases with Re. All of
these results agree well with experimental observations
Crystal structure analysis of intermetallic compounds
Study concerns crystal structures and lattice parameters for a number of new intermetallic compounds. Crystal structure data have been collected on equiatomic compounds, formed between an element of the Sc, Ti, V, or Cr group and an element of the Co or Ni group. The data, obtained by conventional methods, are presented in an easily usable tabular form
Overdamped dynamics of a Brownian particle levitated in a Paul trap
We study the dynamics of the center of mass of a Brownian particle levitated
in a Paul trap. We focus on the overdamped regime in the context of
levitodynamics, comparing theory with our numerical simulations and
experimental data from a nanoparticle in a Paul trap. We provide an exact
analytical solution to the stochastic equation of motion, expressions for the
standard deviation of the motion, and thermalization times by using the WKB
method under two different limits. Finally, we prove the power spectral density
of the motion can be approximated by that of an Ornstein-Uhlenbeck process and
use the found expression to calibrate the motion of a trapped particle
Solid State Drives: A New Problem
This paper explores the characteristics of solid state drives (SSDs) with regard to the probability that an update to the data will require a page be relocated. Storage characteristics of SSDs are described and the problem of drive wear is explained. Probabilities are developed for increases and decreases in value at the byte level. The byte-level probabilities are then extended to the SSD storage page. The implications of those probabilities for drive wear are examined and extended to file design considerations. In addition, the wear implications of current practices are pointed out where appropriate. In the end, the issue of frequency of data update becomes a new consideration that must be taken into account in all phases of system design
