Abstract:Men established in traditional (mechanical engineering, n = 100) and nontraditional (elementary school counseling, n = 100) careers were compared on their career compromise choices (sex type vs. prestige), adherence to masculinity ideology, gender role conflict, and job satisfaction. Men established in traditional (mechanical engineering, n = 100) and nontraditional (elementary school counseling, n = 100) careers were compared on their career compromise choices (sex type vs. prestige), adherence to masculinity ideology, gender role conflict, and job satisfaction. The engineers tended to choose sex type over prestige; the school counselors indicated a clear preference for prestige. The engineers reported more traditional gender role attitudes. The gender role variables had little predictive value for the career compromise choices.

Magnetic resonance (MR) imaging has been used in the temporomandibular joint (TMJ) primarily to define the disk position. This report examines altered morphology and signal intensity characteristics of the TMJ disk as they relate to the severity of internal derangement. Two hundred sixteen joints in 133 patients with a history of such derangement. were imaged with MR. Disk position, signal intensity, morphology, and the presence of osteoarthritis were determined for each joint. The normal disk was not anteriorly displaced and had a normal "bow-tie" shape. A grade 1 disk was anteriorly displaced and had a normal shape; a grade 2 disk was anteriorly displaced and had an abnormal shape. Forty (19%) joints were considered normal; none of these exhibited osteoarthritis. One hundred thirty-nine (64%) joints were grade 1; osteoarthritis was found in 17%. Thirty-seven (17%) were grade 2; osteoarthritis was found in 95%. All forty normal joints had high or intermediate signal intensity in the disk. Osteoarthritic joints had a higher percentage of disks with diminished intensity (P less than .0001). Severe or untreated osteoarthritis is known to be a complication of TMJ internal derangements; hence this grading system seems to correlate with the severity of internal derangement.

The purpose of this study was to evaluate the effectiveness of a creative-comprehensive approach (CCA) when compared with a performance approach (PA) on the acquisition of basic music concepts and skills by general college students. In the CCA, students were directly involved in the process of creating original music by assuming the roles of composer, performer, and analytic listener. Students in the PA were engaged in the performance and aural analysis of preselected folk and traditional music. A pretest-posttest design involving intact groups was used as the method of research. The resulting effects of the two instructional modes on three dependent variables revealed no difference in achievement on aural discrimination competence from pretest to post-test in the sampled groups. There was, however, evidence suggesting that the CCA was superior to the PA in developing students' self-confidence in dealing with basic music concepts and skills. Additional data indicated a slight, but not significant, difference in performance achievement between the two groups in favor of the CCA.

S1188th Meeting: Acoustical Society of America S11 epithelium of the cochlea. The results of this exposure can be divided into two groups. One group had a small 10--30-dB TTS which recovered completely by 30 days. The cochlea had no unusual hair-cell losses. The second group of chinchillas demonstrated as much as a 90-dB TTS across a broad range of frequencies which resolved to a 40--50-dB PTS. The cochleas of these animals had nearly total losses of outer hair cells throughout the entire cochlea, with scattered small losses of inner hair cells. The traumatic potential of this longterm exposure is in contrast with the relatively innocuous effects of exposure to the same impulses for one hour. 3:15 F6.
