Reports on two pilot studies conducted in the United Kingdom, one at a university library and one at a public library, that investigated the use of electronic books. Both studies raised concerns regarding the usability of the products and conclude that improvements are needed in terms of portability, readability, and navigability. (LRW)

Global positioning system (GPS) has many uses. They include navigation, location finding, vehicle tracking, surveying, autonomous control of highway construction equipment, scientific activities, asset location and entertainment. The GPS is a constellation of 24 satellites located in a 10,000-mile radius orbit in a way that allows for at least six…

In the early 1990s, numerous academic libraries adopted the web as a communication tool with users. The literature on academic library websites includes research on both design and navigation. Early studies typically focused on design characteristics, since websites initially merely provided information on the services and collections available in…

To date, LIS studies of workplace information practices have primarily focused on occupations that require a university education, and, consequently, little is known about the information practices of blue-collar workers. This study uses a qualitative case study approach to examine the workplace information practices of a blue-collar worker--a…

Purpose: The purpose of this paper is to propose that the measurement of salivary amylase activity is an effective index to evaluate the stress of a ship navigator for safe navigation training and education. Design/methodology/approach: Evaluation comes from the simulator and actual on-board experiments. The subjects are real captains who have…

There is a general sense today that constructivist teaching is not up to the task of preparing students for high-stakes exams. In this article, the authors describe a highly effective constructivist approach used to teach students in a learning situation that takes the meaning of "high stakes" to another level. They talk about teachers of "cane…

This guide was created to accompany workshops on learning to use electronic networks. It is less than a complete introduction to networks, but is a good tool for those learning to use them. An introduction defines networks, discusses the most important of them, and provides other useful concepts. Understanding and using electronic mail are…

Orienteering is land navigation through unknown countryside with map and compass. This article describes an orienteering program in the Action Education Curriculum, State University of New York, College at Purchase. (KM)

This is the fifth in a series on shortened versions of the Avionics Fundamentals and Aviation Electronics Technician R (Radar) Courses. The first four studies indicated that the initial revisions of the courses led to substantial savings in training time, but that the graduates from the revised courses were slightly inferior to graduates from the…

Scientists often use the "slingshot effect" (also called the "gravity assist") of the gravitational field of a planet to increase or decrease the velocity of a spacecraft. Examples of this effect, puzzling aspects, a qualitative explanation, details of necessary calculations, a thermodynamic analogy, and other topics are discussed. (JN)

Effective navigation is becoming more and more critical to the success of electronic commerce (E-commerce). It remains a challenge for educational technologists and Web designers to develop Web systems that can help customers find products or services without experiencing disorientation problems and cognitive overload. Many E-commerce Web sites…

Discusses navigation in instructional hypertext programs and describes two preliminary studies that investigated concrete versus abstract representations for backward navigation. Topics include representation and hypermedia sign systems; and consistency in the forms designers use for navigation buttons. (LRW)

Tracks the development of sonar from a submarine detecting device to a seabed plotting device. Describes applications of the technology in fishing and oceanography. (MDH)

Sixth graders at Kamehameha Elementary School ascended a high mountain peak, successfully orienting themselves for over 5 miles using topographical maps and compasses and the knowledge, skills, and attitudes acquired at school. The article describes the program, noting the knowledge and tools students used to accomplish their goal. (SM)
