    Contextualization: no passing fad

    Get PDF
    Originally prepared for an international conference on the churches and China attended by Chinese patriotic Christians, this paper focuses on the processes of indigenization and contextualization. Asian discussions of these processes are related to two Canadian illustrations: the development of indigenous structures by the Lutheran church in America-Canada Section; and the struggle of Canada\u27s northern natives to preserve their past and to shape their future in the face of a proposed pipeline across their land. Asian and feminist conclusions are affirmed: contextualization is the way towards, rather than a threat to, catholicity, universality and transcendence

    Projected technological requirements for remote sensing of terrain variables

    Get PDF
    Contributions of remote sensing to hydrogeomorphology and terrain analysis are reviewed in order to identify characteristics that should receive support in system and sensor configuration planning. Fluvial morphological studies, peak discharge modeling, and hydrogeomorphic floodplain mapping using large scale (1:12,000) to small scale (1:750,000) orbital photography are discussed as well as quantitative assessment of terrain variables for specific applications

    An Observed Entanglement of Lagenorhynchus obliquidens in the High Seas Driftnet Area in the North Pacific

    Get PDF
    In August, 1991, an entanglement event was observed in the High Seas Driftnet area in the North Pacific. This description of an entanglement of Lagenorhynchus obliquidens is the first such documented report of dolphins entangling while bowriding. One of the entangled dolphins was rescued from the driftnet

    Non-linear Plasma Wake Growth of Electron Holes

    Full text link
    An object's wake in a plasma with small Debye length that drifts \emph{across} the magnetic field is subject to electrostatic electron instabilities. Such situations include, for example, the moon in the solar wind wake and probes in magnetized laboratory plasmas. The instability drive mechanism can equivalently be considered drift down the potential-energy gradient or drift up the density-gradient. The gradients arise because the plasma wake has a region of depressed density and electrostatic potential into which ions are attracted along the field. The non-linear consequences of the instability are analysed in this paper. At physical ratios of electron to ion mass, neither linear nor quasilinear treatment can explain the observation of large-amplitude perturbations that disrupt the ion streams well before they become ion-ion unstable. We show here, however, that electron holes, once formed, continue to grow, driven by the drift mechanism, and if they remain in the wake may reach a maximum non-linearly stable size, beyond which their uncontrolled growth disrupts the ions. The hole growth calculations provide a quantitative prediction of hole profile and size evolution. Hole growth appears to explain the observations of recent particle-in-cell simulations
