    Hip Hop Hermeneutics: How the Culture Influences Preachers

    Get PDF
    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 Alaska Department of Natural Resources Planning and Research Sectio

    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

    Get PDF
    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

    Full text link
    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

    Get PDF
    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
