Seafarer Nainoa Thompson proved Western scientists wrong when they claimed his Pacific Island ancestors lacked the navigational skills to make their 2,500 mile trans-Pacific voyages, guided only by the stars and the sea. In the same way, schools must model different, more affiliative ways of gaining and imparting knowledge. (MLH)

Presents a proposed information environment (PROPIE) for enhanced interaction and value-adding of electronic documents that allows users multiple ways to query intuitively and navigate information in an electronic document. Highlights include user interface technologies; visualization and interactive techniques; query and browsing processes; and…

Do humans integrate experience on specific routes into metric survey knowledge of the environment, or do they depend on a simpler strategy of landmark navigation? The authors tested this question using a novel shortcut paradigm during walking in a virtual environment. The authors find that participants could not take successful shortcuts in a…

When navigating by path integration, knowledge of one's position becomes increasingly uncertain as one walks from a known location. This uncertainty decreases if one perceives a known landmark location nearby. We hypothesized that remembering landmarks might serve a similar purpose for path integration as directly perceiving them. If this is true,…

The need to support users of the Internet with the selection of information is becoming more important. Learners in complex, self-organising Learning Networks have similar problems and need guidance to find and select most suitable learning activities, in order to attain their lifelong learning goals in the most efficient way. Several research…

Describes the preparations to observe the transit of Venus in 1761, the event that opened channels of scientific communication between Europe and America. (LS)

This document contains a U.S. Navy Rate Training Manual and Nonresident Career Course which form a self-study package to teach the theoretical knowledge and mental skills needed by the Opticalman Third Class and Opticalman Second Class. (Opticalmen maintain, repair, and overhaul telescopic alidades, azimuth and bearing circles, binoculars,…

This instructor's manual is designed to serve as a guide for a one-year course for training fishermen on board training vessels of 100 to 200 gross tons. Fourteen chapters are included to deal with the subjects and problems most frequently faced by skippers and other instructors on training vessels. Chapter titles are (1) The Training Vessel, (2)…

THE MATERIAL IN THIS COURSE IN MARINE NAVIGATION AND SMALL CRAFT OPERATION ON INLAND AND INTERNATIONAL WATERS WAS DEVELOPED BY AN INDIVIDUAL AUTHOR FOR USE IN TRADE SCHOOL PREPARATORY AND EXTENSION CLASSES FOR MALE ADULTS WHO PLAN TO OPERATE BOATS. THE OBJECTIVE IS TO PREPARE THE SMALL BOAT OPERATOR FOR HIS OWN CONTINUATION IN THE STUDY OF…

This manual provides information on all phases of air navigation for navigators and student navigators in training. It develops the art of navigation from the simplest concepts to the most advanced procedures and techniques. The text contains explanations on how to measure, map, and chart the earth; how to use basic instruments to obtain…

In the design of visual simulation equipment for training systems, one key decision is the nature of the image storage medium to be used. One consideration in this complex issue is the adequacy of the depth cues which can be derived from imagery based on two- rather than three-dimensional sources. Although motion parallax is a relatively minor…

Numerous radio stations across the nation perform nonbroadcast services in areas ranging from aviation, forestry protection, and telephone maintenance to amateur and citizen radio. These services can be grouped in four general categories: (1) safety, (2) industry, (3) land transportation, and (4) miscellaneous purposes. This bulletin briefly…

Explains how to approach the school administration when soliciting funds for the skydiving club in the school. (GA)

Presents a bibliography of books for upper elementary students. The books deal with aspects of space in the seventies, changing concepts of the universe, and how today's science and technology are trying to answer the questions these concepts raise. (Author/GA)

Describes a simulated experiment in which a ship's position is determined by the Doppler principle. The formulas derived for the real satellite system are given. (CC)
