This study examined the extent to which samples of professionals working in industry are interested in unionization and some of the factors that are associated with this interest. "Business" professionals (» = 26) and "science" professionals (« = 38) indicated in a survey questionnaire how they felt about the necessity for collective bargaining. They also completed selected sections of the Management Styles Survey to report how they felt about their jobs, the fairness of people, their supervisors' style, and their organizations. Although the professionals as a whole were close to the midpoint in felt need for collective bargaining, science professionals felt much more need than did business professionals (r = .57). Additional covariance was associated with disbelief in the fairness of people, an authoritarian rather than a consultative boss, job insecurity, and perceived lack of trust in the organization.

A recent investigation by P. H-S. Jen et al. [J. Acoust. Soc. Am. 57, S42 (A) (1975)] has shown that during acoustic stimulation the cricothyroid musclc (CTM) responds in echolocating bats. Previous studies have shown that the rat emits ultrasonic cries which can be used to echolocate. Our study attempts to determine the existence of the acoustic CTM response in this species. Electromyography of the CTM was obtained in ten rats. Rats were stimulated with pure tones between 5 and 60 kHz. During acoustic stimulation the rate of the action potential response was obtained using varying intensities and frequencies. Interspike interval histograms were also obtained during spontaneous activity from the CTM. Latencies from the CTM response were found to be within the range of 8 to 30 msec. Data are presented which support the acoustic CTM response in the rat.

Survey data from a sample of 58 U.S. and six Canadian medical schools were used to describe the current network of medical schools and their affiliates. Results showed that each medical school in the study averaged over 11 affiliates. The largest percentages of affiliates reported were in the categories of "community" hospitals (that is, the nongovernmental, not-for-profit hospitals), Veterans Administration hospitals, and city hospitals. Characteristics of the medical schools, such as class size, ownership, year established, and the presence of a university hospital, were not related to either the number or the kind of affiliates. However, the sizes of the affiliated institutions were associated with the year the medical school was established, the presence of a university hospital, and the class size of the medical school.

The acquisition of pure tone and speech audiometric data from a remote location would be especially useful in schools, industrial applications, military usage, physicians' practices, and hospital-medical-center environments. Data transmission using standard ASCII encoding (with RS-232c interface) provide an efficient means of controlling the acoustic parameters in audiometric testing. Essentially, in a digitally controlled audiometer, the devices receive and transmit control commands at a 300 baud rate readily compatible with available computer hardward interfaces. Unique design concepts including simultaneous use of the acoustic coupler modes for speech and data transmission are discussed. Using FSK coding techniques the ordinary telephone system may be employed to remotely relate audiological diagnostic information between two locations.
