    This paper is directed toward helping achieve a better understanding of traditional law ways among Alaska's Athabascan Indians and of the present state of the administration of law in the "bush"-village Alaska. An outgrowth of the 1970 Bush Justice Conference sponsored by the Alaska Judicial Council, the paper's primary purpose is to help facilitate establishment of more appropriate delivery and administration of legal services for ethnically distinct populations of Alaska.Introduction / Traditional Athabascan Culture / Social Organization and Leadership / Values and Their Relationship to Law Ways / Athabascan Law Ways — The Philosophical Basis / The Pragmatic Structure and Operation of Athabascan Law Ways / Major Offenses and Their Resolution (Adultery, Theft, Murder) / Summary of Athabascan Law Ways / Law Ways and Culture Change / Past and Present Law Ways: Some Disjunctions / Reference

    Northern Eskimo Law Ways and Their Relationship to Contemporary Problems of "Bush Justice": Some Preliminary Observations on Structure and Function

    This paper describes the how the basic values, personality, and culture of Northern (Inupiat) Eskimos contribute to attitudes toward conflict and their society’s capacity to resolve conflict. The paper analyzes the influence of Anglo-American agents of change on that capacity and, especially, the legal system and procedures that developed in the post-contact use of the village council to resolve disputes. It discusses the formal intervention of state law through the magisterial system and its interaction with Eskimo law ways that the village council encouraged. A comparison of village councils and magistrate courts points out the apparent success of the councils due to their unique fit with Eskimo values and expectations. Finally, shortcomings of .the current magistrate system are analyzed with recommendations for policy adaptations.Introduction / The Genesis of Eskimo Law Ways in Aboriginal Conflict Resolution / Aboriginal Eskimo Conflict Resolution: An Overview / American Intervention and Eskimo Law Ways / The Village Council / The Contemporary Period: The Magistrate System / Implications for Bush Justice / Conclusion / Bibliograph

    Head-mounted spatial instruments II: Synthetic reality or impossible dream

    Get PDF
    A spatial instrument is defined as a spatial display which has been either geometrically or symbolically enhanced to enable a user to accomplish a particular task. Research conducted over the past several years on 3-D spatial instruments has shown that perspective displays, even when viewed from the correct viewpoint, are subject to systematic viewer biases. These biases interfere with correct spatial judgements of the presented pictorial information. The design of spatial instruments may not only require the introduction of compensatory distortions to remove the naturally occurring biases but also may significantly benefit from the introduction of artificial distortions which enhance performance. However, these image manipulations can cause a loss of visual-vestibular coordination and induce motion sickness. Consequently, the design of head-mounted spatial instruments will require an understanding of the tolerable limits of visual-vestibular discord

    A synthetic environment for visualization and planning of orbital maneuvers

    Get PDF
    An interactive proximity operations planning system, which allows on-site planning of fuel-efficient, multi-burn maneuvers in a potential multi-space-craft environment has been developed and tested. This display system most directly assists planning by providing visual feedback in a synthetic virtual space that aids visualization of trajectories and their constraints. Its most significant features include (1) an 'inverse dynamics' algorithm that removes control nonlinearities facing the operator and (2) a stack-oriented action-editor that reduces the order of control and creates, through a 'geometric spreadsheet,' the illusion of an inertially stable environment. This synthetic environment provides the user with control of relevant static and dynamic properties of way-points during small orbital changes allowing independent solutions to otherwise coupled problems of orbital maneuvering

    Interactive orbital proximity operations planning system

    An interactive, graphical proximity operations planning system was developed which allows on-site design of efficient, complex, multiburn maneuvers in the dynamic multispacecraft environment about the space station. Maneuvering takes place in, as well as out of, the orbital plane. The difficulty in planning such missions results from the unusual and counterintuitive character of relative orbital motion trajectories and complex operational constraints, which are both time varying and highly dependent on the mission scenario. This difficulty is greatly overcome by visualizing the relative trajectories and the relative constraints in an easily interpretable, graphical format, which provides the operator with immediate feedback on design actions. The display shows a perspective bird's-eye view of the space station and co-orbiting spacecraft on the background of the station's orbital plane. The operator has control over two modes of operation: (1) a viewing system mode, which enables him or her to explore the spatial situation about the space station and thus choose and frame in on areas of interest; and (2) a trajectory design mode, which allows the interactive editing of a series of way-points and maneuvering burns to obtain a trajectory which complies with all operational constraints. Through a graphical interactive process, the operator will continue to modify the trajectory design until all operational constraints are met. The effectiveness of this display format in complex trajectory design is presently being evaluated in an ongoing experimental program

    Exocentric direction judgements in computer-generated displays and actual scenes

    One of the most remarkable perceptual properties of common experience is that the perceived shapes of known objects are constant despite movements about them which transform their projections on the retina. This perceptual ability is one aspect of shape constancy (Thouless, 1931; Metzger, 1953; Borresen and Lichte, 1962). It requires that the viewer be able to sense and discount his or her relative position and orientation with respect to a viewed object. This discounting of relative position may be derived directly from the ranging information provided from stereopsis, from motion parallax, from vestibularly sensed rotation and translation, or from corollary information associated with voluntary movement. It is argued that: (1) errors in exocentric judgements of the azimuth of a target generated on an electronic perspective display are not viewpoint-independent, but are influenced by the specific geometry of their perspective projection; (2) elimination of binocular conflict by replacing electronic displays with actual scenes eliminates a previously reported equidistance tendency in azimuth error, but the viewpoint dependence remains; (3) the pattern of exocentrically judged azimuth error in real scenes viewed with a viewing direction depressed 22 deg and rotated + or - 22 deg with respect to a reference direction could not be explained by overestimation of the depression angle, i.e., a slant overestimation
