To understand the importance of coordination and collaboration for ROV teams, let us examine some of the typical tasks that ROV operators might be required to perform (Cooke & Shope, 2004; Gugerty, DeBoom, Walker, & Burns, 1999). To do so, we will use the members of a U.S. Air Force Predator crew as an example. The team consists of three members: an Air Vehicle Operator (AVO) who pilots the aircraft, a Payload Operator (PLO) who operates the surveillance equipment, and a Data Exploitation, Mission Planning, and Communications Operator (DEMPC) who is responsible for mission planning. In the course of a mission, the AVO is responsible for the take off and landing of the aircraft. Because they fly the aircraft from a remote location, AVOs are generally required to use visual input from a camera mounted on the nose of the aircraft to guide their flight. Once in the air, the PLO can operate cameras and sensors mounted on the belly of the plane to gather information. The DEMPC, who is in contact with the upper echelons of the organization, provides the AVO with the desired heading and the PLO with target coordinates.

In recent years, guides to hiking trails and wilderness areas have enjoyed an increase in popularity. Here, Douglas J. Ernest and Lewis B. Herman evaluate more than 100 such books.

Within the past 20 years hiking and backpacking have enjoyed rapid growth among Americans as favorite outdoor activities. From 1965 to 1977 the number of hikers almost tripled, from 9.9 million to 28.1 million, while national forest visitor days among hikers and mountaineers increased from 4 million in 1966 to 11 million in 1979. Accompanying this growth in interest has been a boom in books about the sport. These include both “how‐to‐do‐it” volumes and guides to specific geographical areas. Each year brings another spate of books, yet to this compiler's knowledge no bibliography of hiking guides to the Rocky Mountains, one of North America's premier outdoor regions, has yet been attempted. This bibliography is an effort to correct that situation.

Just‐in‐time (JIT) production methods were popularized by the excellent results achieved by Japanese industry. When it became evident during the 1970s that the Japanese were gaining markets previously dominated by Americans, there was considerable interest in learning how Japanese industry operates. Then, during the early 1980s, Toyota’s highly effective JIT production system had a particular appeal to Americans who were trying to understand Japanese production methods. While Taichi Ohno, creator of Toyota’s production system, credits Henry Ford as the originator, it is now known that Ernest Kanzler, one of Ford’s subordinates, played a major role in developing JIT production methods. This article reports Ford’s and Kanzler’s contributions and explores the possible influence that Frederick W. Taylor may have had on the development of this approach at the Ford Motor Company.

Ever since Robert Ezra Park and Ernest Burgess published their classic research on Chicago which described “how” residential neighborhoods follow a distinct ecological pattern, generations of urban practitioners and theoreticians have been arguing about “why” they are spatially distributed. This essay is designed to demonstrate the utility of Visual Sociology and the study of Vernacular Landscapes to document and analyze how the built environment reflects the changing cultural identities of neighborhood residents. It is strongly suggested that a visual approach can also help build a bridge between various theoretical and applied disciplines that focus on the form and function of the metropolis. While discussing some of these often-competing models, the text is illustrated by a selection of photographs taken in Brooklyn, New York whose neighborhoods over the past century have been a virtual Roman fountain of ethnic transitions. Although many of the oldest and newest residents of Brooklyn such as Chinese, Italians, Jews, and Poles would be familiar to Park and Burgess, others such as Bangladeshis, Egyptians, and Koreans would not. Ideas about Old and New cities from the “classical” to the “post-modern”; from Park and Burgess to Harvey and Lefebvre are also synthesized via the insights of J. B. Jackson.
