This study of one echolalic boy with autism assessed the effects of interlocutor directiveness (high and low) and knowledge of the lexical items (known and unknown) on the frequency of occurrence of immediate verbal imitations (IVIs). The occurrence of IVIs produced in response to the condition in which unknown items were presented with a high directive style differed significantly (p < .05) from the occurrence of IVIs produced in response to the other conditions. This finding suggests that previous studies attributing increases in IVIs solely to either linguistic or social variables did not account for interaction effects. A visual display of the data indicated that the first presentation of a lexical item accounted for most of the increases in IVIs relative to subsequent presentations of the same item. This observation is in line with the interpretation of Leonard, Schwartz, Folger, Newhoff, & Wilcox, (1979), that normal children imitate the most "informative" items.

In this study, the effect of the word processor on third semester Spanish students at the University of Arizona was examined. The study was performed over two semesters, using a control and an experimental group each time. The communicative language approach for second language learning was implemented in a cooperative learning environment for both control and experimental groups. Control groups used paper and pencil to write their class essays and experimental groups used the word processor. The experimental groups outperformed the control groups. The semester variable by itself was also significant. However, there was no significant interaction between group and semester. Replication studies are needed to validate the results of this study.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / The Data Acquisition and Distribution System (DADS) transparently collects data from a ship's combat system and transfers that data by satellite to a shore site. The system was developed by the Naval Surface Warfare Center Port Hueneme Division (NSWC PHD). DADS supports surface ship data collection, display, distribution, and debrief capabilities. NSWC PHD personnel used equipment assets developed in-house and purchased data communications hardware and software to develop DADS. A satellite terminal was placed outside Building 1380, and analog telephone lines were installed, linking the Data Communications and Control Laboratory (DCCL) with the Satellite Earth Station in Santa Paula, CA. A shipboard DADS transparently taps a ship's Combat System and collects selected data files. The data is compressed and archived. After shore site personnel select the data required for analysis, DADS encrypts it, and transmits the data via satellite to the shore site for reconstruction and analysis. DADS is unattended. The portable shipboard system equipment and software is controlled from a shore site via the International Maritime Satellite (INMARSAT). The DCC supports transmission speeds of up to 9.6 kilobits/second when connected to a communication system with this capability.

International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / The Department of Defense, through a Tri-Service Program Office, is developing the Common Airborne Instrumentation System (CAIS) to promote standardization, commonality, and interoperability among aircraft test instrumentation systems. The advent of CAIS will change how the DoD test community conducts business. The CAIS program will allow aircraft test and evaluation facilities to utilize common airborne systems, ground support equipment, and technical knowledge for airborne instrumentation systems. The CAIS Program Office will conduct requirements analyses, manage system upgrades, and provide full life cycle support for this system. It is initiating several requirements contracts to provide direct ordering opportunities for DoD users to easily procure defined test instrumentation hardware. The program office will provide configuration management, inventory control, maintenance support, system integration, engineering support, and software management. In addition, it will continue to enhance the current system and develop new items to meet future requirements. Where existing equipment provides added benefit, this equipment may be added to the official CAIS family.
