Integrating Working At Home With Information Systems Management, Computerized Conferencing & Communications Center, Joseph C. Schuh

Computerized Conferencing and Communications Center Reports

The history of computerization has its origin in the automation of manual processes - searching out the segments that could be put on a computer. The intended result was that the entire job would be done faster and cheaper. Thus, current computer-based information systems tend to make more efficient use of computers than people. The management function, on the other hand, often seems to focus on competitive skills and salesmanship rather than on the ability to attract and hold talented people. But, such impersonal factors that have driven management practices are changing. There has been a complete reversal in the …

Programming Language Requirements For Human Communication Structures Or Computer Conferencing, Computerized Conferencing & Communications Center, Peter Gordon Anderson

Computerized Conferencing and Communications Center Reports

Our overall goal is to be able, simply and quickly, to construct computer conferencing systems for new requirements, applications, and even experimental ideas or fantasies. One way to view this requirement is as the creation of a highly parameterized conferencing system itself. Our view, however, is that of a programming language; i.e., an integrated notational system for the specification of communication structures and the associated actions or computation to be taken by the computer system hosting the structure.

A communication structure consists of a group of people (and storage devices) each endowed with some characteristics, and some means of person-to-person …
