Controllers' Perceptions of the Importance of Accounting Skills to Lodging Managers

Are managerial accounting skills important to all managers? Which of the common managerial accounting skills are the most important to the non- accounting manager? The authors report on their descriptive research gathered from controllers in the hospitality industry which provides guide- lines for managers in these areas.

Male and Female Hotel Controllers in the '90s

Female hotel controllers generally are expected to display the same managerial characteristics and are evaluated on the same criteria as male controllers, yet there is a significant difference in their base salaries. The authors explore some of the differences between male and female hotel controllers and make overall comparisons with previously-collected data.

Design and construction of a portable force-reflecting manual controller for teleoperation systems

A man-machine system called teleoperator system has been developed to work in hazardous environments such as nuclear reactor plants. Force reflection is a type of force feedback in which forces experienced by the remote manipulator are fed back to the manual controller. In a force-reflecting teleoperation system, the operator uses the manual controller to direct the remote manipulator and receives visual information from a video image and/or graphical animation on the computer screen. This thesis presents the design of a portable Force-Reflecting Manual Controller (FRMC) for the teleoperation of tasks such as hazardous material handling, waste cleanup, and space-related operations. The work consists of the design and construction of a prototype 1-Degree-of-Freedom (DOF) FRMC, the development of the Graphical User Interface (GUI), and system integration. Two control strategies - PID and fuzzy logic controllers are developed and experimentally tested. The system response of each is analyzed and evaluated. In addition, the concept of a telesensation system is introduced, and a variety of design alternatives of a 3-DOF FRMC are proposed for future development.
