High-resolution CRT displays are subject togeometric distortion: lines that are straight in the internal coordinates of the graphics software and hardware are curved when projected onto a plane in the observer’s line of sight. As the available resolution of CRT screens increases, it becomes more difficult to measure and correct for this distortion. We present a simple, highly accurate method for determining the mapping between internal coordinates and the viewing plane. It requires that an observer, using a calibration program, adjust triples of displayed points until they are collinear. A metal straightedge placed between the observer and the screen aids in this judgment. We describe the calibration of an IBM Enhanced Graphics Display in high-resolution mode (350 × 640 pixels), and illustrate how to use the estimated mapping to choose internal coordinates to draw undistorted figures that are accurate to within 0.5 pixel. The method can be used to assess or to correct the accuracy of visual displays. The method is relevant to experiments in spatial vision, spatial perception, perception of dot patterns, and any application in which geometrically accurate stimuli are required. 相似文献

In our rapidly changing environment, both profit and non-profit organizations confront an increasing demand for technological,
economic, and social innovation. In response to this demand, organizations are taking on the role of “change agents” by transforming
existing practices into innovative action. Libraries, as centers that accumulate and disperse knowledge, can support these
organizations in their “change agent” roles. This paper delineates the way public libraries can help organizations meet the
increasing need for external information associated with innovation. Policy issues concerned with efficient information transfer
to user organizationss are specified, and two concrete examples of information transfer systems are described. In order to
best utilize existing knowledge,personal-professional assistance in selecting potentially innovative,impersonal written materials is recommended.

This study examined the usefulness of an 8-week applied problem-solving training program. Specifically, the study examined (a) whether problem-solving training that emphasised self-management principles would be useful, (b) if the effects of training would persist over time, (c) whether an individual difference variable (problem-solving appraisal) would affect training outcomes, and (d) whether the cognitive responses of the subjects during the course of training were related to their problem-solving appraisal or the change process. Results indicated that problem solving training was effective at enhancing students’ problem-solving appraisal, and that the self-report changes were maintained at a 1 year follow-up. In particular, training seemed most useful for students who initially appraised their problem solving very negatively. Finally, the results suggested that the process-oriented cognitive responses were related to students' initial problem-solving self-appraisal as well as the impact of training. Implications of the results are discussed in terms of counselling interventions, problem solving training, the interpersonal influence process, and future research. 相似文献

Philosophical issues related to theoretical and methodological developments in counseling are addressed, especially related to epistemology (theory of knowledge) and ontology (theory of reality). Social systems theory is described as an epistemologically and ontologically significant challenger to psychological theory, which has traditionally predominated as a foundation for counseling approaches. Recent developments from cognitive biology are used to demonstrate how systems theory may be metatheoretical to the psychological point of view, accounting for all that psychological theory can account for, and more. 相似文献

Counseling training programs have failed to differentiate between and among behavioral, cognitive, and unconsciousness dimesnsions. This omission has resulted in confusion and competition in many counseling curricula in that valuable programs are competing for space rather than being integrated systematically. This article proposes a multilevel model of intentionality which integrates the several aspects of the counselor-client relationship. In turn, this integration of behavioral, cognitive, and unconscious dimensions will have important applications in counselor daily practice. 相似文献

A computer-controlled system that detects spontaneous activity (locomotion and rearing) and diurnal activity rhythms in small animals is described. Automatic recording of subtotals during test periods provides data about habituation (nonassociative learning). The system is relatively inexpensive to construct. Fabricated from highly reliable circuit components, it provides replicable measures that enable comparisons between different experimental treatments to be made using parametric statistics. 相似文献
