Purpose. People who use augmentative and alternative communication (AAC) vary widely in their skills and communication needs. Interventions have been developed to meet different needs, but have met with varied success. Attempts to discover why interventions succeed or fail are hindered by the lack of detailed description of the research participants and the environments in which they communicate. This paper reviews the information commonly given about AAC research participants and presents guidelines for the description of people who use AAC, their conversation partners and their communicative environments. Method. Electronic databases were searched for AAC intervention research reports published between 1990 and 2004. Data on research participants and their communication environments were extracted from reviewed papers. Information given in published papers and variables known to affect communication were presented to an expert group. A modified Nominal Group technique was used to decide what information should be reported in AAC intervention research. Results. Guidelines for participant description that link with the World Health Organization International Classification of Functioning, Disability and Health were developed from the results of the nominal group. Conclusions. Detailed information is needed to demonstrate efficacy of AAC interventions. Guidelines for participant description are presented and discussion of their utility is now needed.

This article focuses on the cases of chronic motion sickness. Numerous investigators have studied the general problem of motion sickness. Many of these workers have, for obvious reasons, recently directed their efforts toward obtaining an understanding and control of seasickness. On this latter question certain writers have estimated that approximately 40 per cent of a given population would, if at sea, develop seasickness. The procedure utilized was as follows. During the routine neuro-psychiatric and psychological interview each naval recruit, in consecutive order, was queried about any history of motion sickness. This questioning was continued until 100 cases of chronic motion sickness had been clearly identified. All cases showing isolated instances of illness when in motion were excluded from consideration. Thus only those yielding evidence of frequent and relatively severe illness when in some type or types of conveyance are included in this study. In practically all of these 100 cases vomiting and other gastro-intestinal symptoms accompanied the traditional picture of general malaise

This article presents information on a study on a state's contribution to American men of science. This study, based upon a questionnaire mailed to the 24,278 members of the 1922-23 "Who's Who in America," revealed that the majority of these notables of the 1920-30 decade were fathered by minority elements in the nation's population. In fact, seventy percent were fathered by less than seven and a half percent of the nation's men. This report is based upon the contributions of the state of Illinois to the 1927 edition of the Biographical Directory. The method used has been essentially survey in nature. The survey indicates that of the 13,500 men and women scientists included in the volume the state of Illinois has in some way contributed approximately 10 percent of the biographies. The data indicate that 625 men and women scientists were employed within the state in 1927. A total of 557 students received their degrees from institutions within the state. This group comprises approximately four percent of the 13,500 biographies in the 1927 edition.
